Bituminous mixes are most commonly used all over the world in flexible pavement construction. It consists of asphalt or bitumen used as a binder and mineral aggregate which are mixed together, laid down in layers and then compacted. Under normal circumstances, conventional bituminous pavements if designed and executed properly perform quite satisfactorily but the performance of bituminous mixes is very poor under various situations. Today’s asphaltic concrete pavements are expected to perform better as they are experiencing increased volume of traffic, increased loads and increased variations in daily or seasonal temperature over what has been experienced in the past. In addition, the performance of bituminous pavements is found to be very poor in moisture induced situations. Considering this a lot of work has been done on use of additives in bituminous mixtures and as well as on modification of bitumen. Research has indicated that the addition of polymers to asphalt binders helps to increase the interfacial cohesiveness of the bond between the aggregate and the binder which can enhance many properties of the asphalt pavements to help meet these increased demands. However, the additive that is to be used for modification of mix or binder should satisfy both the strength requirements as well as economical aspects.

Flexural Behaviour of Steel Fibre Reinforced Geopolymer Concreteijtsrd
Concrete is the most used construction material from ancient days. It was expected that the production of cement would be increased from about from 1.5 billion tons in 1995 to 2.2 billion tons in 2020. But 2018 china using 2.37 billion tons individually. India is the second largest producer of cement in the world. Cement industry is expected to reach 550 – 600 million tons per annum at 2025. The cement production contributes nearly 8 of worlds global warming due to emission of greenhouse gases, such as CO2, to the atmosphere. Hence, it is essential to find a substitute material for cement. The technology geopolymer concrete found as alternative for this problem. In this present research, cement is replaced with Fly Ash and GGBS in different percentages with steel fibers. The studies show that the load carrying capacity of most of the gpc mix was in the most cases more than that of conventional ordinary Portland cement concrete mix. The fresh and hardened properties of geopolymer concrete were found with and without steel fiber. The mechanical characteristics of all the examined mixes are to be enhanced by the GGBS content, in both plain and steel fibre reinforced geopolymer concrete. A comparative analysis has been carried out for normal conventional concrete to that of the steel fibre reinforced geopolymer concrete under ambient curing in relation to compressive, split tensile, flexural strengths. As the fibre content generally increases compressive, split tensile and flexural strengths are proportionally increased. G. Jegatheeswaran | K.

Modifications of construction materials have an important bearing on the building sector. Several attempts have been therefore made in the building material industry to put to use waste material products, e.g., worn out tyres, into useful and cost effective items. Success in this regard will contribute to the reduction of waste material dumping problems by utilizing the waste materials as raw material for other products. The present proposal involves a comprehensive laboratory study for the newer application of this waste material in the preparation of fibrous concrete. The primary objective of investigation is to study the strength behavior i.e. compressive strength, impact resistance of rubberized concrete with rubber chips.

As concrete is the most abundant material used in the world, it contains aggregate content of around 60 to 70 %. Since aggregate are being used rapidly there has been a scarcity in the avaibility of these materials. This research investigates the effect of partially replacing aggregates by burnt brick bats and lateritic fines in concrete respectively for M25 grade concrete. The incorporation is done for 5%, 10% and 15% of burnt brick bats for coarse aggregate and by talking 15% of lateritic fines as constant for fine aggregate by conducting compressive strength test which gave the optimum value of 15% for natural sand. The compressive strength, split tensile strength and flexural strength was conducted. The results showed density of of the concrete incorporating brick and laterite was lower compared to conventional concrete, the concrete with 5% burnt brick and 15% lateritic soil showed increased strength for 7 days compared to normal concrete but when 28 days test was conducted the strength was similar to conventional concrete. The split tensile and flexural strength of replaced concrete was found to be lower than the nominal concrete.
Natural resources are vanishing universal while at the similar time the generated wastes from the industry are
growing substantially. The sustainable development for construction requires the use of nonconventional and
innovative materials, and recycling of demolished and waste materials so to compensate the lack of natural
resources and to find alternative ways of conserving the environment. So, this paper presents the consequences
of an experimental study carried out to evaluate the power-driven properties of concrete mixtures in which fine
aggregate (sand) was swapped with Copper Slag (CS) while coarse aggregates were swapped by used and
recycled concrete coarse aggregate (RCA) from demolished structure or building. Both the coarse and fine
aggregate were replaced with percentages 0% (for the control mixture), 10%, 20%, 30%, of Copper Slag by
weight ratio. Tests were performed for properties of new concrete and toughened Concrete simultaneously.
Slump test was conducted to regulate the workability of the several design concrete mix. Compressive strength
and split tensile strength were determined at 7, 28 days of curing completely.
The results show that workability shrinkages slightly with rise in Copper Slag ratio, however workability for
the illustrations were within the prearranged boundary for M25 concrete. Test results shown substantial
enhancement in the strength assets of simple concrete by the insertion of CS alone whereas a reverse tendency
in observed for growing proportion of RCA in the illustration. The result of this study work displayed that
Copper slag in addition recycled concrete aggregate can be efficiently used in physical concrete as a standby of
coarse aggregate and fine aggregate (sand) respectively.
Utilization of pond fly ash as a partial replacement in fine aggregate with u...eSAT Journals
Abstract Due to increase in the growth of industrial sectors the power requirement of the country is rapidly increasing. India depends on Thermal Power as its main source, thus increase in power requirement every year. Present scenario of our country shows 75 % of country’s total installed power generation is thermal of which coal-based generation is 90%. The coal reserves of the country are predominately of lower grades (average of 35% ash content), non cooking and as a result more than 110 million MT coal ash is being generated every year. Ash generation may likely reach to 170 million MT by 2012. Use of coal brings huge amount of ash every year. Lots of research has been carried out for effective utilization of fly ash in construction industries due to its fine particles and Pozzolonic properties. But little literature is available on pond ash utilization. Pond ash being coarser and less Pozzolonic than fly ash can be used as fine aggregates in concrete by partial replacement of sand. As per M60 Mix Design in this project we will replace the alccofine and fine fly ash partially with cement and pond fly ash as a replacement of fine aggregate. In mix G1, G2, G3 we will replace cement with alccofine 4% and fine fly ash 26% and pond fly ash varies 10%, 20%, and 30% as replacement of F.A. Similarly in mix G4,G5,G6 alccofine 6% and fine fly ash 24% and pond fly ash same as 10%,20%,30%. The Concrete specimens will tested at different age level for Mechanical Properties of concrete, namely, Cube Compressive Strength, Split Tensile Strength, Flexural Strength with other properties such as Compacting Factor, with respect to 7,28,56,90 Days strength. The main aim of our study as project is to get the economical and eco friendly High strength Concrete (HSC).

Natural resources are depleting worldwide while at the same time the generated wastes from the industry are increasing substantially. The sustainable development for construction involves the use of nonconventional and innovative materials, and recycling of waste materials in order to compensate the lack of natural resources and to find alternative ways conserving the environment. So, this paper presents the results of an experimental investigation carried out to evaluate the mechanical properties of concrete mixtures in which fine aggregate sand was replaced with Copper Slag CS while coarse aggregates was replaced by recycled concrete aggregate RCA from demolished structure. Both the fine and coarse aggregate were replaced with percentages 0 for the control mixture , 10 , 20 , 30 , of Copper Slag by weight. Tests were performed for properties of fresh concrete and hardened Concrete. Slump test was conducted to determine the workability of the various design concrete mix. Compressive strength and split tensile strength were determined at 7, 28 days of curing. The results indicate that workability decreases slightly with increase in Copper Slag percentage, though workability for the sample were within the prescribed limit for M25 concrete. Test results indicate significant improvement in the strength properties of plain concrete by the inclusion of CS alone while a reverse trend in observed for increasing percentage of RCA in the sample. The synergistic effect of CS and RCA on the designed sample concrete revealed that the percentage of CS is the more decisive factors than the percentage of RCA in deciding the performance of the concrete in terms of compressive and tensile strength. The outcomes of this research work showed that Copper slag and recycled concrete aggregate can be effectively used in structural concrete as a replacement of fine aggregate sand and coarse aggregate respectively. Futher, it substantiate towards sustainable construction approach because of its dual advantage of controlling menace of solid waste disposal along with its subsequent environmental pollution and increasing the cost efficiency and carbon efficiency of the product.

The aim of the investigation is to replace natural fine aggregatewith Air Cooled Blast Furnace Slag in OPC concrete. At present, nearly million tons of slag is being produced in the steel plants, in India. The generation of slag would be dual problem in disposal difficulty and environmental pollution. Some strategies should be used to utilize the slag effectively. Considering physical properties of metallurgical slags and a series of possibilities for their use in the field of civil constructions, this report demonstrates the possibilities of using air cooled blast furnace slag as partial replacement of sand in concrete. A total of five concrete mixes, containing 0%, 12.5%, 25%, 37.5% and 50% partial replacement of regular sand with air cooled blast furnace slag are investigated in the laboratory. These mixes were tested to determine axial compressive strength, split tensile strength, and flexural strength for 7days, 28days, 56days and 90days.

Bamboo, as a fast growing renewable material with a simple production process, is expected to be a sustainable alternative for more traditional structural materials, such as concrete, steel and timber. The diminishing wood resource and reduction in natural forests, particularly in the tropics, have focused world attention on the need to identify a substitute building material that should be renewable, environment friendly and widely available. The tensile strength of bamboo fiber can be comparable to that of steel, and the average fracture toughness of bamboo can be higher than that of aluminum alloy. Bamboo grows at rapid rates, it almost grows to its full size in a few months and finishes developing within five years. Bamboo is the world’s fastest growing woody plant. It grows approximately 7.5 to 40cm a day, with world record being 1.2m in 24 hours in Japan. Bamboo grows three times faster than most other species. Commercially important species of bamboo usually mature in four or five years in time.

Performance of lateritic concrete under environmental harsh conditioneSAT Journals
Abstract This is an investigation of weathering characteristics of Laterized concrete with laterite-fine aggregate ratio as a factor. It was done with a view of ascertaining the suitability of laterite as aggregate substitutes at 0, 10, 20, 30 and 40% of fine aggregate used in the construction industry. The weathering characteristics were examined by conditioning laterized concrete cubes to varying temperatures, chemical and alternate wetting and drying, which all represent the operating weather conditions (wet and dry seasons) in tropics, including Nigeria. The mix proportion used was 1:2:4, the curing age of the laterized concrete was based on 28days curing age, while the compressive strength of the treated laterized concrete cubes was determined. The result of this research showed that the compressive strength of laterized concrete with laterite-fine aggregate ratio variation decreases when subjected to alternate wetting and drying and increases when subjected to magnesium sulphate (Mg2SO4). It was also discovered that a laterized concrete with a laterite-fine aggregate ratio of 20% conditioned to a temperature range of 100oC attained optimum compressive strength of 12.90Nmm-2 Keywords: Laterized Concrete, Comprehensive strength, Weathering Characteristics

Natural resources are depleting worldwide while at the same time the generated wastes from the industry are increasing substantially. The sustainable development for construction involves the use of nonconventional and innovative materials, and recycling of waste materials in order to compensate the lack of natural resources and to find alternative ways conserving the environment. So, this paper presents the results of an experimental investigation carried out to evaluate the mechanical properties of concrete mixtures in which fine aggregate sand was replaced with Copper Slag. The fine aggregates sand was replaced with percentages 0 for the control mixture , 10 , 20 , 30 , 40 , 50 , 60 , 80 , and 100 of Copper Slag by weight. Tests were performed for properties of fresh concrete and Hardened Concrete. Compressive strength and Flexural strength were determined at 7, 28 and 56days. The results indicate that workability increases with increase in Copper Slag percentage. Test results indicate significant improvement in the strength properties of plain concrete by the inclusion of up to 80 Copper slag as replacement of fine aggregate sand , and can be effectively used in structural concrete. Also as percentage of Copper Slag increased the density of concrete increased. The workability of concrete increased with increase in percentage of copper slag. Toughness of copper slag is found to be more, which increases the compressive and flexural strength of concrete.

In order to prepare the bitumen mix, the most commonly fillers in the form of fractions, fine aggregates and coarse aggregates are primarily used. In some part of the country, it is not possible that the various size fractions of aggregates are available easily. Hence, these will be transported by covering large distance which indirectly enhances the cost of the project. To fulfill the power requirements, large numbers of thermal power plants around forty have been installed throughout the countries which are reported to produce ashes of around 125Million Ton per year. Such huge amount of coal ashes possesses the challenging problems for their disposal in the forms of health hazards, dangers to environment, etc. A proper care is to be required for its disposal for the safety of environment, wildlife as well as human life too. As a result, to minimize the impacts of these materials, this research study is required to use it in a productive way which will fulfill all the needs of the society.

Performance Evolution of Modified Bituminous Concrete Mix Using Waste Plasticijtsrd
Generally a bituminous mixture is a mixture of coarse aggregate, fine aggregate, filler and binder. A Hot Mix Asphalt is a bituminous mixture where all constituents are mixed, placed and compacted at high temperature. HMA can be Dense Graded mixes DGM known as Bituminous Concrete BC . Bituminous mix is generally used as a surface course and wearing course in flexible pavements since it is necessary that the wearing course must provide a smooth riding surface that is dense and at the same time take up wear and tear due to traffic. The development of transportation plays an important role in the development of nation. With flexible pavements being widely used in India, steps must be taken to increase the life of the bituminous pavements. Flexible pavements are often plagued with problems of cracking and rutting due to repeated traffic loads. Hence one needs to address these problems in order to improve the performance of flexible pavements.

As concrete is the most abundant material used in the world, it contains aggregate content of around 60 to 70 %. Since aggregate are being used rapidly there has been a scarcity in the avaibility of these materials. This research investigates the effect of partially replacing aggregates by burnt brick bats and lateritic fines in concrete respectively for M25 grade concrete. The incorporation is done for 5%, 10% and 15% of burnt brick bats for coarse aggregate and by talking 15% of lateritic fines as constant for fine aggregate by conducting compressive strength test which gave the optimum value of 15% for natural sand. The compressive strength, split tensile strength and flexural strength was conducted. The results showed density of of the concrete incorporating brick and laterite was lower compared to conventional concrete, the concrete with 5% burnt brick and 15% lateritic soil showed increased strength for 7 days compared to normal concrete but when 28 days test was conducted the strength was similar to conventional concrete. The split tensile and flexural strength of replaced concrete was found to be lower than the nominal concrete.
Natural resources are vanishing universal while at the similar time the generated wastes from the industry are
growing substantially. The sustainable development for construction requires the use of nonconventional and
innovative materials, and recycling of demolished and waste materials so to compensate the lack of natural
resources and to find alternative ways of conserving the environment. So, this paper presents the consequences
of an experimental study carried out to evaluate the power-driven properties of concrete mixtures in which fine
aggregate (sand) was swapped with Copper Slag (CS) while coarse aggregates were swapped by used and
recycled concrete coarse aggregate (RCA) from demolished structure or building. Both the coarse and fine
aggregate were replaced with percentages 0% (for the control mixture), 10%, 20%, 30%, of Copper Slag by
weight ratio. Tests were performed for properties of new concrete and toughened Concrete simultaneously.
Slump test was conducted to regulate the workability of the several design concrete mix. Compressive strength
and split tensile strength were determined at 7, 28 days of curing completely.
The results show that workability shrinkages slightly with rise in Copper Slag ratio, however workability for
the illustrations were within the prearranged boundary for M25 concrete. Test results shown substantial
enhancement in the strength assets of simple concrete by the insertion of CS alone whereas a reverse tendency
in observed for growing proportion of RCA in the illustration. The result of this study work displayed that
Copper slag in addition recycled concrete aggregate can be efficiently used in physical concrete as a standby of
coarse aggregate and fine aggregate (sand) respectively.

Abstract Due to increase in the growth of industrial sectors the power requirement of the country is rapidly increasing. India depends on Thermal Power as its main source, thus increase in power requirement every year. Present scenario of our country shows 75 % of country’s total installed power generation is thermal of which coal-based generation is 90%. The coal reserves of the country are predominately of lower grades (average of 35% ash content), non cooking and as a result more than 110 million MT coal ash is being generated every year. Ash generation may likely reach to 170 million MT by 2012. Use of coal brings huge amount of ash every year. Lots of research has been carried out for effective utilization of fly ash in construction industries due to its fine particles and Pozzolonic properties. But little literature is available on pond ash utilization. Pond ash being coarser and less Pozzolonic than fly ash can be used as fine aggregates in concrete by partial replacement of sand. As per M60 Mix Design in this project we will replace the alccofine and fine fly ash partially with cement and pond fly ash as a replacement of fine aggregate. In mix G1, G2, G3 we will replace cement with alccofine 4% and fine fly ash 26% and pond fly ash varies 10%, 20%, and 30% as replacement of F.A. Similarly in mix G4,G5,G6 alccofine 6% and fine fly ash 24% and pond fly ash same as 10%,20%,30%. The Concrete specimens will tested at different age level for Mechanical Properties of concrete, namely, Cube Compressive Strength, Split Tensile Strength, Flexural Strength with other properties such as Compacting Factor, with respect to 7,28,56,90 Days strength. The main aim of our study as project is to get the economical and eco friendly High strength Concrete (HSC).

So, this paper presents the results of an experimental investigation carried out to evaluate the mechanical properties of concrete mixtures in which fine aggregate sand was replaced with Copper Slag CS while coarse aggregates was replaced by recycled concrete aggregate RCA from demolished structure. Both the fine and coarse aggregate were replaced with percentages 0 for the control mixture , 10 , 20 , 30 , of Copper Slag by weight. Tests were performed for properties of fresh concrete and hardened Concrete. Slump test was conducted to determine the workability of the various design concrete mix. Compressive strength and split tensile strength were determined at 7, 28 days of curing. The results indicate that workability decreases slightly with increase in Copper Slag percentage, though workability for the sample were within the prescribed limit for M25 concrete. Test results indicate significant improvement in the strength properties of plain concrete by the inclusion of CS alone while a reverse trend in observed for increasing percentage of RCA in the sample. The synergistic effect of CS and RCA on the designed sample concrete revealed that the percentage of CS is the more decisive factors than the percentage of RCA in deciding the performance of the concrete in terms of compressive and tensile strength. The outcomes of this research work showed that Copper slag and recycled concrete aggregate can be effectively used in structural concrete as a replacement of fine aggregate sand and coarse aggregate respectively. Futher, it substantiate towards sustainable construction approach because of its dual advantage of controlling menace of solid waste disposal along with its subsequent environmental pollution and increasing the cost efficiency and carbon efficiency of the product.

Taking into account the environmental perspective as well, there is significant environmental damage as a result of the excessive usage of polythene in daily operations. The requirement of the hour is to use the leftover polythene for some advantageous purposes because polythene is not biodegradable.

An Experimental Study of Soil Stabilization with Cement and Polymerijtsrd
The aim of the study was to determine the value of Unconfined compressive strength and CBR values of Soil after stabilizing it with Cement and Polymer. Soil stabilization has been widely used as an alternative to substitute the lack of suitable material on site. The utilization of nontraditional compound stabilizers in soil improvement is developing every day. In this investigation a lab try was led to assess the impacts of waterborne polymer on unconfined pressure quality on sandy soil and CBR Test on clayey soil .The lab tests were performed including grain size of sandy soil, unit weight, and unconfined compressive quality test. The sand and different measures of polymer 2 , 3 , and 4 and concrete 20 , 30 , and 40 were blended in with every one of them into mixture utilizing hand blending in research center conditions. The examples were exposed to unconfined pressure tests to decide their quality following 7 days of restoring. The consequences of the tests showed that the waterborne polymer fundamentally improved the unconfined pressure quality of sandy soils which have weakness of liquefaction. Polymer altered the building properties of soil through physical holding. The amount of polymer required to modify the engineering properties was directly related to specific surface and soil particle coating thickness. Polymer amended soils displayed a reduced performance compared to cement amended soils.

Self compacting concrete for slip form pavingeSAT Journals
Abstract Slip form paving has been extensively used worldwide for construction of pavements. During the process of paving, concrete mix with a slump less than 50 mm is placed in front of a paver. Because of the low consistency of the mix, a great deal of vibration is needed to move entrapped air and compact the concrete. There is a need to overcome problem by designing a concrete that would not require vibration to compact the concrete mix, at the same time stability after extrusion and high flexural strength. Mix design based on the absolute volume concept was adopted to fabricate SFSCC. Volume of paste of 0.38 and water content of 200 kg/m3 was kept constant throughout the study. Cement content was varied from 360 to 425 kg/m3, 3 mixes of SCC with GGBS (SFSCC-S), 3 mixes of SCC with 2% of alccofine replaced by cement (SFSCC-SA) and 3 mixes of SCC with 2% of metakaolin replaced by cement (SFSCC-SM) is reported. The quantity of polypropylene fibers used in all the mixes was 900 gm/m3. Slump, spread, green strength and compaction factor were evaluated for all the 9 mixes. To simulate the practical construction process, a mini paver system was fabricated. The strength parameters compressive and flexural strength of concrete was evaluated at 7 days and 28 days. Keywords: Slip form paving, alccofine, SCC, GGBS, metakaolin, SFSCC, SP.

Standardization and Formulations of Calotropis ProceraYogeshIJTSRD
Plants growing in arid regions have elicited increased attention, because the hostile environment, in which these plants survive, forces them to develop chemical protective systems through adaptation which is rarely found in vegetation of other ecosystems. Furthermore, many of the plants grow in areas, where the dependence on traditional, plant based medicines over industrially produced pharmaceuticals persists to this day. The two plants, Calotopris Procera giant milkweed, also named C. Persica and Calotropis gigantea crown ower , have been used widely in traditional medicine in North Africa, the Middle East, and South and South East Asia. This has led to extensive research on the chemical constituents of the plants. Both plants are known to be sources of cardenolides, and newer research has yielded a number of interesting cancer active constituents. In addition, extracts of both plants have remarkable nematocidal, molluscidal and insecticidal activities. In many regions, the wood of Calotropis plants has been used as a building material and as a source of fuel. In addition, certain parts of the plants have been used as feed for livestock. In other regions, Calotropis plants are seen as invasive species that threaten local plant life and that due to their toxicity also pose a threat to grazing eld animals.

Review of the Diagnosis and Treatment of ParalysisYogeshIJTSRD
Paralysis is a complete loss of motor power in any muscle group. When paralysis affects all four extremities, it is called quadriplegia when it affects only the lower extremities, paraplegia and when it affects the extremities on one side of the body, hemiplegic. For this reason, the term paralysis is generally reserved for more focal, less stereotyped weakness, for instance, affecting all the muscles innervated by a peripheral nerve. Many different anatomical lesions and etiologies can cause paralysis and determine its treatment. Bikash Debsingha | Dr. Gourav Kr.

Automatic Query Expansion Using Word Embedding Based on Fuzzy Graph Connectiv...YogeshIJTSRD
The aim of information retrieval systems is to retrieve relevant information according to the query provided. The queries are often vague and uncertain. Thus, to improve the system, we propose an Automatic Query Expansion technique, to expand the query by adding new terms to the user s initial query so as to minimize query mismatch and thereby improving retrieval performance. Most of the existing techniques for expanding queries do not take into account the degree of semantic relationship among words. In this paper, the query is expanded by exploring terms which are semantically similar to the initial query terms as well as considering the degree of relationship, that is, “fuzzy membership- between them. The terms which seemed most relevant are used in expanded query and improve the information retrieval process. The experiments conducted on the queries set show that the proposed Automatic query expansion approach gave a higher precision, recall, and F measure then non fuzzy edge weights.

A New Proposal for Smartphone Based Drowsiness Detection and Warning System f...YogeshIJTSRD
This paper proposes a Smartphone based system for the detection of drowsiness in automotive drivers. The proposed system uses three stage drowsiness detection technique. The first stage uses the percentage of eyelid closure PERCLOS which is obtained by capturing images with the front camera of the Smartphone with a modified eye state classification method. The system uses near infrared lighting for illuminating the face of the driver during night driving. The second step uses the voiced to the unvoiced ratio VUR obtained from the speech data from the microphone, in the event PERCLOS crosses the threshold. The VUR is also compared with a threshold and if it is a value greater than that of the threshold, it moves on to the next verification stage. In the final verification stage, touch response is required within the stipulated time to declare whether the driver is drowsy or not and subsequently sound an alarm. To awake the driver, a vibrating mechanism is done and also the live GPS location is also sent to an emergency contact. We have studied eight other reference papers for the literature review. The system has three advantages over existing drowsiness detection systems. First, the three stage verification process makes the system more reliable. The second advantage is its implementation on an Android smart phone, which is readily available to most drivers or cab owners as compared to other general purpose embedded platforms. The third advantage is the use of SMS service to inform the control room as well as the passenger regarding the loss of attention of the driver.

Now a days with the rapid development of multimedia technologies, research on safety and security are becoming more important. Multimedia data are generated and transmitted through the communication channels and the wireless media. The efficiencies of encryption based on different existing algorithms are not up to the satisfactory limit. Hence researchers are trying to modify the existing algorithm or even develop new algorithms that help to increase security with a little encryption time. Here in this paper, we have furnished a new technology to modify the AES algorithm which gives more security with a little encryption time and which can be used to encrypt using 128 bit key. Theoretical analysis on the proposed algorithm with the existing reveals the novelty of our work. Here we have proposed a technique to randomize the key and hidden the key data into an encrypted digital image using the basics concept of cryptography and also using the concept of digital watermarking, the concept of key hide has also been encrypted. We have also proposed a new technique to reposition the pixels to break the correlation between them. So, the proposed scheme offers a more secure and cost effective mechanism for encryption. Next on the AES criteria list good performance. Widespread market adoption will require reasonably good performance on a variety of platforms, ranging from easy tocrack smart cards to the largest servers. Good algorithm performance includes speed for the encryption and decryption process as well as the key schedule.

The study sought to determine the extent to which the usage of social media in the marketing of agricultural products in South West Nigeria can enhance farmers turnover. It employed the survey research design to collect data with the help of a structured questionnaire to elicit information from respondents selected from six 6 south western states. Research data were analysed using structural equation modelling. The results showed that the use of social media WhatsApp and Facebook in marketing of agricultural products significantly enhances farmers turnover. The managerial implication is that use of Whatsapp and Facebook in the marketing of agricultural products for the enhancement of farmers’ turnover was found to have significant influence on the enhancement in farmers’ turnover from agricultural products. Policy makers in government should provide the enabling environment for the telecommunication companies to enhance their reach by installing their facilities across the length and breadth of the country so that the network coverage will be strong at all times so that the benefits of social media usage will not be constrained.

A mathematical equation which involves a function and its derivatives is called a differential equation. We consider a real life situation, from this form a mathematical model, solve that model using some mathematical concepts and take interpretation of solution. It is a well known and popular concept in mathematics because of its massive application in real world problems. Differential equations are one of the most important mathematical tools used in modeling problems in Physics, Biology, Economics, Chemistry, Engineering and medical Sciences. Differential equation can describe many situations viz exponential growth and de cay, the population growth of species, the change in investment return over time. We can solve differential equations using classical as well as numerical methods, In this paper we compare numerical methods of solving initial valued first order ordinary differential equations namely Euler method, Improved Euler method, Runge Kutta method and their accuracy level.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

VARIOUS LAYERS OF PAVEMENTS
The base-course of bituminous pavement consists of
aggregates with gradations in the form of rock
ballasts (stones), gravels and sand particles. These
should be perfectly bounded with each other through
the binding material and are primarily used as the
foundations over which the surface course or binders
are placed.
The binder course, consist of a mixture of bitumen
and aggregate is used in the form of an intermediate
course or layer. This layer lies in the middle of the
surface course and base course. This layer might also
be as the first layer of bitumen for the bituminous
resurfacing of two layers.
The asphaltic concrete or bituminous concrete is the
perfect aggregate mixture in which the grading of
aggregate is such that the highest size of the
aggregate should be 25 mm and minimum size in the
form of filler should be 0.075 mm. The quantity of
bitumen to be added should be such that the it should
help to create a proper bond between the aggregates
and the mix in compacted state should be non-porous,
impermeable and elastically stable.
PREVIOUS RESEARCHES ON
POLYETHYLENE
The IPC, Institute for Interconnecting and
Packaging Electronic Circuits published a testing
manual in 1995 to determine the various
characteristics of polyethylene. The elongation,
strength in tension and Young’s Modulus of
organic free films with the use of ASTM D 618,
ASTM D 882, ASTM D 1005 and ASTM D
2370.
The Thermo-Gravity analysis (TGA) technique
has been used to study the various properties of
polymers [Sichina et al. (2001)]. As per the study,
this technique determines the rate of change of
quantity and mass of a specimen with respect to
time or temperature in controlled conditions of
atmosphere. It measures the oxidative and thermal
stability of the individual materials and their
corresponding compositions. It is highly
beneficial for study and analysis of polymeric
materials which includes the thermo-sets, thermo-
plastics, fibres, composite films and coatings of
paints and elastomers.
PREVIOUS RESEARCHES ON
POLYETHYLENE
Bindu and Beena (2010) conducted a study that
deals with the use of waste plastic in the form of
stabilizer additive in stone mastic asphalt
designed mix. This designed mix was then
subjected to undergo testing for tensile and
compressive strength, tri-axial compression test,
Marshall Stability tests. It was concluded that
only 10% content of shredded plastic may results
into higher durability of the mix along with the
great performance.
As per the study carried out by Fernandes et al.
(2008) that includes the use of polymer based
modified asphalt in the form of elastomeric
compound namely “SBS (Styrene Butadiene
Styrene)”. It was later compared with the
characteristics of Modified binder after addition
of shale oil and aromatic oil which enhances the
compatibility of the mix. The time bound
properties of the mix the SBS PMBs were
analyzed in a dynamic shear rheometer (DSR). It
was concluded that the aromatic compounds and
shale oils consists of similar impacts over the
micro structure, stability and most importantlythe
visco-elastic nature of the polymer based
modified asphalt.
Gawande et al. (2012) analyzed the experimental
approach towards the overlay of bituminous
surface, placed on October, 1987 in Lwarence
County, Kentucky. The laboratory experiment
used the limestone, bottom ash and natural sand in
the form of fine aggregates. The conclusion made
by this study represents that around 50% higher
bituminous content is necessary for the mixture
due to its absorptive properties of bottom ash used
as aggregates. However, the increase in the
quantity of bituminous content would definitely
rise to the overall unit price of the material.
Moreover, if limestone and natural sand is used
with the bottom ash seems to improvise the basic
performance of the surface mixture along with its
characteristics of skid resistance.
A bi-annual demonstration project was started by
Prusty (2012) in which around 50% of aggregates
were replaced by their substitute as bottom ash in
the flexible pavement. This project included the
considerable experiments of expected
experimental influences along with the
performance of the pavements in laboratory and
fields both. The field performance of the roadways
had been monitored by using the remote sensing
in terms of resistance to strains, temperature
probes along with the on-site pavement analysis.
In 2003, the damage induced by the moisture to
the bituminous design mixes having bottom ash is
thoroughly studied and analyzed. Total 8
bituminous design mixes were produced having a
single kind of bitumen content, two types of
aggregates, bottom ash from three different
sources and lime as additive by the use of

principles mentioned in AASHTO T-283. The use
of lime improves the damage induced by the
moisture to the bituminous design mixes when
measured by the TSR. The value of TSR must be
above 80% for a good mix. Although, the use of
lime and bottom could not change the indirect
strength in tension, the mixes having stone chips
produced the higher amount of indirect strength in
tension when compared with that in dry condition
[Pareek et al. (2012)].
Another research study was conducted in which
the type of aggregate had impacts to determine the
nature of emulsion in terms of anionic or cationic.
The rate of reaction of aggregates completely
depends upon the proportion of negative charge
and its random distribution. E.g. the aggregates
constituted of higher silica content are found to be
acidic in nature and has evenly distribution of
negative charges on their surfaces. Even, these
charges are proved to be responsible for the strong
adhesive bonding between the cationic emulsions
and aggregates [Sabina et al. (2009)].
As per Reinke and Glidden (2002), the
performance evaluation of hot mix asphalt having
bottom ash as content was tested in the laboratory.
The scope of this study was to promote the use of
bottom ash in the form of aggregate in wearing
course, base course and sub-base course. This
study was inspired by three way objectives to
evaluate the design mix stability which includes
the determination mechanical properties of
bituminous mix having bottom ash content,
evaluation of stability of the mixes using Marshall
Test Method and evaluation of engineering
parameters of Marshall Cube in the form of
appearance and texture. The major conclusions
drawn from the study indicates that the specimen
having bottom ash is of extremelysuperior quality
in terms of strength, flow, hardness and stiffness.
As a result, the higher strength will be imparted to
the pavement and may able to resist the heavily
loaded traffic. The major limitation for the use of
bottom ash in the bituminous designed mixes is
the increase in the content of air voids that may
leads to the decrease in the density of the mixture.
The investigation for the practicability to use the
fly ash as the extender to asphalt is done by
Yousefi (2009). It also included determining the
impact of various parameters such as particles
size, etc on process of replacement. It was
concluded that it was highly reasonable to replace
the volume asphalt having medium flyash by40%
if used in dry climatic regions while 30% when
used in the moist climatic regions.
Moghaddam and Karim (2012) experimentally
analyzed the results of bottom ash on physical
characteristics of the bituminous pavement mix. It
was also considered to analyze the impacts of use
of bottom ash for the improvement of performance
parameters of the pavement distress. Total four
samples having variable content of bottom ash
was considered. At various temperature
conditions, the various properties like creep,
fatigue, resilient modulus and permanent
deformation are also considered. The performance
of the mix was ascertained by the use of VESYS
model. The conclusions represented in the favour
of bottom ash to be used as a filler to improve the
resistance to stripping and characteristics of
resilient modulus. The bottom ash had no impact
on rut depth and serviceability conditions but with
rise of temperature, surface cracks to the
pavements get increased.
CONCLUSION
The following conclusions are drawn from this study:
The aromatic compounds and shale oils consist of
similar impacts over the micro structure, stability
and most importantly the visco-elastic nature of
the polymer based modified asphalt.
The bottom ash has no impact on rut depth and
serviceability conditions but with rise of
temperature, surface cracks to the pavements get
increased.
It has been highly reasonable to replace the
volume asphalt having medium fly ash by 40% if
used in dry climatic regions while 30% when used
in the moist climatic regions.
