The present work aims to identify the major chemical groups and to evaluate the anti-radical activity of 12 recipes of medicinal plants used in the treatment of malaria among children, pregnant women and adults in two lake villages (Ganvi , Aguegues Daho) of southern Benin. All the recipes contain molecules able to trap the 2,2-diphenyl-1-picrylhydrazyl (DPPH) which is a free radical. This activity would be due to the phenolic compounds identified in the phytochemical screening and whose presence in these recipes has been confirmed by quantitative test performed in a spectrophotometer. Aqueous extract obtain by decoction of recipes 3, 1 and 4 (E3, E1, E4) of the child have the higher contents of total phenolics compounds and good anti-radical activity compared to other extracts. The aqueous extract obtain by decoction of the recipe 3 which has the strongest content of total polyphenols (668.16 mg EAG/g DM) was the most active for trapping DPPH with an IC50 of 0.095 mg/mL similar to those of butylated hydroxyanisole (0.090 mg/mL) and quercetin (0.100 mg/mL) that are reference antioxidants used in this study. These results justify the use of these traditional recipes.
A Comparison between Natural and Synthetic Food Flavoring Extracts Using Infr...IOSR Journals
Food is the basic necessity of life. One works hard and earns to satisfy our hunger .But at the end of the day, many of us are not sure of what we eat. We may be eating a dangerous flavors and dyes. Often, we invite diseases rather than good health. The purpose of this article is to detect the presence of food adulterants in some common foods and to create awareness about the artificial tests and dyes. A study of the IR spectra and the optical activitiy of two natural and artificial most common used flavor and colors (Vanilla and Strawberry) were detected.

Evaluation of fungicides and biological agents for the management of mango an...Agriculture Journal IJOEAR
Abstract— Mango is an important fruit crop in area and production in Gujarat also, where it is cultivated over an area of about 130.1 thousand hectares with annual production of 911.3 thousand tones with productivity of 7.01 tones/ha. Its plantation has become quite popular in the districts of Valsad, Junagadh, Navsari, Kutch, Surat, Amreli and Bhavnagar because of favourable agro-climate condition. Mango is affected by number of diseases at all the stages of its development right from plant in nursery to the fruit in storage or transit. Mango is prone to many fungal diseases like Anthracnose, Rhizopus rot, Stem end rot, Penicillum rot, Black mould rot, Mucor rot, Phyllosticta rot, Pestalotiopsis rot, Macrophoma rot and powdery mildew, leading to heavy loss in yield. Among these diseases, anthracnose is the major disease of mango as it occurs at all the growing parts including leaves, twigs, flowers, fruits except root and trunk throughout the year. Anthracnose caused by Glomerella cingulata (Stoneman) Spauld and H Schrenk (anamorph: Colletotrichum gloeosporioides (Penz.)) appear to be more severe causing devastation of mango fruits during grading, packing, transportation, storage and marketing (Pathak, 1980).

Modeling Truck Movements: A Comparison between the Quick Response Freight Man...inventionjournals
In recent years, with a growing realization of the important impacts of truck traffic on the economy as well as urban congestion and pollution levels, there is a keen interest in modeling truck movements with greater accuracy, robustness, and detail. This paper examines two different approaches for explicitly including truck trips into travel demand forecasting models. The approaches considered are (a) the truck modeling methodology published in the Quick Response Freight Manual (QRFM) and (b) an emerging truck tour-based approach. In this paper, the two approaches are demonstrated and compared using the Birmingham, AL region as a case study and statistical analyses are conducted to evaluate the level of accuracy of both approaches. The results demonstrate that the model using tour-based approach performs better than the one based on the QRFM approach with respect to model accuracy, when compared to field data from the study area. However, the tourbased approach requires a comprehensive data collection and processing effort, whereas the QRFM approach uses the publicly available data such as household and employment data. The decision on the best approach for adoption should be made on a case-by-case basis after considering the tradeoffs between accuracy and data availability and processing requirements. Overall, the findings from this study can be used to support the development of efficient freight truck modeling applications for the Birmingham region. Moreover, lessons learned from the Birmingham case study provide valuable insights that can guide freight modeling efforts of planning agencies in other medium sized communities in the future
Cleft lip and palate - The culprit gene- Identified yet? : A reviewinventionjournals
: Various genetic approaches, including genome-wide and candidate gene association studies as well as linkage analysis, have been undertaken to identify aetiologic factors, but results have often been inconclusive or contradictory. These results may support the presence of aetiologic heterogeneity among populations and the presence of multiple genes involved in the aetiology of CL/P. Despite these difficulties, several different genes have been implicated in harbouring genes that contribute to the aetiology of CL/P. Even though the environmental factors have been understood and can be avoided to stop the formation of this facial anomaly, the genetic pathways still show the whirlphool effect and need to be understood and refined in their expression so that the genes and their actions could be identified and the probably existing single gene or family could be identified and reparative measures to stop its expression could be learned.
Analysis of Cr and Cu in Soils around Selected Automobile Workshops of Kaduna...inventionjournals
In this research, speciation analysis of soil samples from selected automobile workshops of Kaduna Metropolis, Nigeria was carried out. A modified Tessier extraction procedure was employed for the analysis. The concentrations of Cr and Cu in the samples were determined using flame atomic absorption spectrometry (FAAS). The soil samples were digested and extracted using different digestion and extraction media. The results revealed that the concentrations of Cr and Cu in the soils varied from one automobile workshop to another. The result also showed that Cr concentration was minimal in the various extraction media and followed the trend; HNO₃ > MgCl₂ > EDTA > Oxalic acid. Similarly, Cu concentration was found to be highest in the oxide phase, followed by that bound to the exchangeable phase. The distribution followed the trend oxalic acid > MgCl₂ > HNO₃: H₂O₂
The main stake is to detect a defective component or likely to become it during manufacture or inservice inspections, while improving control productivity. In this context, we develop a simulation tool of EC fastened structures testing, integrated to the ANSYS platform, aimed at conceiving testing methods, optimizing and qualifying it. The finite element method has been chosen, it is suitable for this type of problem. Various configurations have been considered for the inspection of a target with a defect in different thicknesses. Due to the impossibility to detect a defect located at a distance much greater than the skin depth δ. Indeed, the eddy currents amplitude are less than 95% of the maximum amplitude beyond a depth greater than 3 δ. We are interested in the detection of defects located at depths higher to three times the skin depth.
Solving Poisson’s Equation Using Preconditioned Nine-Point Group SOR Iterativ...inventionjournals
A well-designed preconditioning of the partial differential equations problems reduces the number of iterations to reach convergence. Dramatic improvements are possible, but the difficulty is to construct the suitable preconditioner.The construction of a specific splitting-type preconditioner in block formulation for a class of group relaxation iterative methods derived from the finite difference approximations have been shown to improve the convergence rates of these methods. This paper is concerned with the application of suitable preconditioning techniques to the Nine-Point Group SOR (N-P SOR) iterative method for solving Poisson’s Equation. Preconditioning strategies which improve the rate of convergence of these iterative methods are investigated. The results reveal the improvements on the convergence rate and the efficiency of the proposed preconditioned Group iterative method.

Synthesis And Characterization of Novel Processable Poly (EtherAzomethine)S C...inventionjournals
The novel dialdehyde 1,1-bis[4-(4-benzaldehyde oxy) phenyl] cyclopentane (III) (BBPC) was synthesized starting from cyclopentanone and phenol to give 1, 1-Bis (4-hydroxy phenyl) cyclopentane (II); followed by reaction with p- fluorobenzaldehyde in N, N-dimethyl formamide (DMAc), containing anhydrous potassium carbonate. New series of poly (ether – azomethine)s were synthesized from (BBPC) with different diamines such as 4, 4’- diamino diphenyl ether (ODA),4,4’-diaminodiphenyl methane(MDA),4-aminophenyl sulfone(SDA), p-phenylene diamines, etc. in DMAc with 5 wt% LiCl by solution polycondensation technique. Inherent viscosities of these polymers were in the range 0.19 to 0.42 dL/g indicating formation of moderate molecular weights. These polymers exhibited good solubility in various polar aprotic solvents such as Nmethylpyrrolidone (NMP), N, N-dimethylacetamide (DMAc) and N,N-dimethyl formamide (DMF), etc. X-Ray diffraction pattern of polymers showed that introduction of cardo cyclopentylidene moiety containing ether linkage would disrupt the chain regularity and packing, leading to amorphous nature. Thermal analysis by TGA showed excellent thermal stability of polymers. The structure- property correlation among these polyazomethines were studied; in view of their potential applications as high performance polymers.

Evaluation of Hepatoprotective Activity and Oxidative Stress parameters of Al...gynomark
In spite of the tremendous advances made, no significant and safe
hepatoprotective agents are available in modern therapeutics.
Therefore, due importance has been given globally to develop plantbased
hepatoprotective drugs, effective against a variety of liver
disorders. The aim of the current study is to screen the alcoholic
extract of Artabotrys hexapetalus (L.f) Bhandari (AEAH) for
hepatoprotective activity in rats which were intoxicated by
paracetamol. This article describes phytochemical (qualitative),
hepatoprotective activity and oxidative stress parameters of the above
selected plant drugs by studying the serum enzyme levels like SGOT,
SGPT, ALP, ACP, Total Bilirubin, Direct Bilirubin, SOD, GSH,
Vitamin C and Catalase levels of the animals treated with hepato
toxicant paracetamol. The alcoholic extract of AEAH reversed the
hepatotoxicity induced by paracetamol in the rats, indicating their
hepato-protective action. The study was also supported by the
histopathological studies which reversed structural damage occurred
due to paracetamol. This study was further supported by the DNA
fragmentation studies which showed the absense of fragmentation of
DNA in AEAH treated groups, indicating the hepatoprotective activity
of Artabotrys hexapetalus (L.f) Bhandari. Hence it can be concluded
that the plant extract possesses a promising hepatoprotective and
antioxidant effect.

Effect of some organic acids on some fungal growth and their toxins productionijabjournal
The effect of eight organic acids (propionic, acetic, formic, lactic, tartaric, citric, oxalic and malic acids) as antifungal agents on the growth of four fungi (Aspergillus flavus, Penicillium purpurogenum, Rhizopus nigricans and Fusarium oxysporum) were studied. The high acidity appeared for oxalic acid being 0.14 at the high concentration (10%), while the lowest acidity recorded for propionic acid and acetic acid being 2.71 and 2.56 at the low concentration (5%). It was observed that, there was no relationship between the efficacy of organic acid and its final pH. Acetic acid (10%) has the highest inhibitory effect on A. flavus being 45.21%, but tartaric acid (5%) and citric acid (5%) gave the same lowest inhibition effect (0.42%).
The lowest value of mycelium dry weight (MDW) of P. purpurogenum was 5.92 g/l when acetic acid was
used (10%), but the highest value was 9.38 g/l when tartaric acid (5%) was used. Formic acid (10%) had a
strong effect on the inhibition growth of R. nigricans being 28.65%, similar to propionic acid (10%), acetic
acid (10%), lactic acid (10%), tartaric acid (10%) and citric acid (10%) being 26.57%, 26.38%, 26.19%,
23.53% and 24.48%, respectively. But malic acid (5%) and oxalic acid (5%) were having a week effect on
R. nigricans being 5.31% and 6.45%, respectively. Lactic acid (10%) has the highest inhibitory effect on F.
oxysporum being 34.45% and the lowest value was in the case of tartaric acid (5%) being 1.68%. Four
treatments were used to determine aflatoxin B1 production. The highest inhibition (50%) was observed by
R. nigricans in the presence of formic acid (10%). Acetic acid in 10% level inhibited the toxic secretion of
A. flavus and P. purpurogenum to become 25% and 40%, respectively. Lactic acid (10%) gave 35% inhibition of toxin production in the presence of F. oxysporum.

The ethanol, ethyl acetate, and hexane extracts of the freshwater clam (Corbicula fluminea) were studied for the total phenolics and total flavonoids. Total phenolics and total flavonoids of the extracts were evaluated using Folin-Ciocalteau and Aluminum chloride colorimetric methods respectively. The findings showed that the total phenolics of the ethanol extract (1.67±0.28mg GAE/g of dried sample) were substantially higher than the total phenolics obtained from the ethyl acetate (0.70±0.00mg GAE/g) and hexane extracts (0.56±0.23mg GAE/g). While the total flavonoids in the ethyl acetate extract displayed a slightly higher total flavonoid (43.84±0.92mg QE/g of dried sample) relative to ethanol (30.41±1.34mg QE/g of dried sample) and hexane extracts (20.28±0.00mg QE/g of dried sample). Using ethanol, the highest yield for extraction was obtained. Ethanol is the best solvent among the three – ethanol, ethyl acetate, and hexane in terms of extraction yield and total phenolics. In addition, it can be inferred that the presence of significant amounts of phenolics and flavonoids suggests that freshwater clam is a promising source of antioxidants that provides nourishing proteins and oxidative stress remedies

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Abstract: The present work aims to identify the major chemical groups and to evaluate the anti-radical activity
of 12 recipes of medicinal plants used in the treatment of malaria among children, pregnant women and adults
in two lake villages (Ganvi , Aguegues Daho) of southern Benin. All the recipes contain molecules able to trap
the 2,2-diphenyl-1-picrylhydrazyl (DPPH) which is a free radical. This activity would be due to the phenolic
compounds identified in the phytochemical screening and whose presence in these recipes has been confirmed
by quantitative test performed in a spectrophotometer. Aqueous extract obtain by decoction of recipes 3, 1 and 4
(E3, E1, E4) of the child have the higher contents of total phenolics compounds and good anti-radical activity
compared to other extracts. The aqueous extract obtain by decoction of the recipe 3 which has the strongest
content of total polyphenols (668.16 mg EAG/g DM) was the most active for trapping DPPH with an IC50 of
0.095 mg/mL similar to those of butylated hydroxyanisole (0.090 mg/mL) and quercetin (0.100 mg/mL) that are
reference antioxidants used in this study. These results justify the use of these traditional recipes.
Keywords: Malaria, plants, phenolic compound, DPPH
I. Introduction
Malaria is a parasitic disease due to presence and multiplication in the body of a protozoan of the genus
Plasmodium transmitted by the bite of a female mosquito, Anopheles, causing intermittent fevers that
determines a erythrocytopathy with hemolysis[1]
. The World Health Organization (WHO) estimates the
incidence of malaria at 198 million cases. Practically always due to Plasmodium falciparum the mortality is
584000 per year and the majority of cases occur in countries of sub-Saharan Africa where we note one child
death every minute [2]
. In Benin, malaria is the leading cause of hospitalization and death both in the general
population, at the level of pregnant women that child under five years [3]
.
One of the major reasons for the development of anaemia in malaria seems to be oxidative stress [4-6]
.
The immune system of the body is activated by infections, including malaria, thereby causing the release of
reactive oxygen species. In addition to this, the malaria parasite also stimulates certain cells to produce reactive
oxygen species thereby resulting in haemoglobin degradation[5,7]
. Indeed, depressed level of plasma antioxidants
has been shown in Plasmodium falciparum infected children and it has been suggested as a possible contributor
to the morbidity and mortality of malaria[8]
. Malaria accounts for around 20% of cases of illness treated in
traditional medicine[9]
. The use of plants to treat themselves in Africa is an integral part of the culture. It should
be recalled that over 80% of Africa's population is dependent on plants for primaries health needs[10,11]
, this
because of the ease of access and modest cost of these herbal medicines. Unfortunately, these drugs quite often
do not benefit from scientific control. So there is a permanent danger regarding the therapeutic doses of the one
part and lethal doses of the other part, from where the margin of safety problem.To contribute to the safety of
the Beninese population and those living in endemic areas malaria this work was initiated and aims to realize the
phytochemical screening of large chemical families and evaluate the anti-radical activity of 12 recipes of
medicinal plants used by the lakeside population of southern Benin (Ganvie, Aguegue Daho) to treat malaria a
view to pharmacological and toxicological studies to confirm or disprove the use made of the traditional
medicinal plants.
II. Material And Methodology
Plant Material
The plant material investigated in this study has been retained after an ethnobotanical survey conducted
throughout the South Benin lakeside population to make an inventory of anti-malarial plants for eventual
pharmacological and toxicological tests. It is composed of 47 plant species distributed into 12 recipes used to

treat malaria in children, pregnant women and adults at “Ganvie” (Atlantic) and “Aguegue Daho” (Oueme) in
Benin. After collection, the plant material has been identified in the National Herbarium of the Department of
Botany, Abomey-Calavi University. The samples were dried over laboratory temperature (25-30 °C) until their
stabilization and then reduced in powder with an electric grinder (Brand RETSCH, Type SM 100).
Methodology
Identification of secondary metabolites
The determination of metabolites was done by differential coloring reaction and/or precipitation of the
major families of chemical compounds contained in plants. So, sterols and terpenes have been identified by the
Liebermann-Burchard test[12]
. The characterization of the compounds belonging to the group of phenolics
compounds was made by the reaction with ferric chloride[13]
. Flavonoids identification was carried out by the
test of cyanidine[14]
. The compounds belonging to the group of tannins have been highlighted by the reaction of
Stiasny[15]
. The free or combined quinone compounds have been disclosed by the reaction of Borntraeger[13,16]
.
The saponosides research is based on foam test; degree of aqueous decoction dilution giving a persistent foam
after shaking[13,17]
. Alkaloids were identified by Mayer test and confirmed by Bouchardat test.
Determination of Phenolic Compounds
The quantification of the phenolic compounds focused on the filtrates hydroethanolic macerated
(water/ethanol: 30/70) and aqueous extract obtain by decoction (distilled water) of plant material subject of this
study. Method of aluminum trichloride (AlCl3) was used to quantify the total flavonoids[18,19]
; condensed tannins
were measured by the method to the sulfuric acid vanillin[20,21]
and the total polyphenols were measured by
Folin-Ciocalteu method[22,23]
.
Determination of the anti-radical activity
The anti-radical activity is determined by the trapping DPPH test. DPPH was dissolved in ethanol.
Different ranges of concentrations in the milligram of each extract were prepared. In dry tubes are introduced
200 µL of extract to analyze and 3800 µL of DPPH solution. After shaking, the tubes are placed in the dark
place for 1 hour, and then the absorbance of the mixture is measured at 517 nm in a spectrophotometer against
the blanc[24]
. The percentage of free radical scavenging DPPH is calculated using the formula:

All the recipes investigated are rich in metabolites such as reducing compounds, saponins and phenolic
compounds. We note the presence of saponins, reducing sugars, flavonoids and condensed tannins in all recipes.
Through against mucilages, quinones and anthraquinones are absent. All the children's recipes investigated as
well as recipes 1 and 4 of the pregnant woman; contain alkaloids, sterols and terpenes. The presence of
alkaloids, flavonoids, sterols and the terpenes recognized for their antiplasmodial property in recipes would
justify their use in the treatment of malaria in Benin [25]

The total phenolics compound contents of our extracts range from 668.16 to 168.54 mg/g. The aqueous
extract obtained by decoction of the recipe 1 of the child has the strongest content of total polyphenols, while
the lowest level was observed in the aqueous decoction of the recipe 2 of the child. The recipes 1 (aqueous
decoction: 668.16mg/g; hydroethanolic macerated: 398.34mg/g), 3 (aqueous decoction: 526.77mg/g;
hydroethanolic macerated: 460.52mg/g) and 4 (aqueous decoction: 479.24mg/g hydroethanolic macerated
377.10mg/g) of the child are the richest in total phenolics compounds. Among the recipes investigated of the
pregnant woman, the aqueous decoction of the recipe 1 (330.56mg/g) has the strongest content of phenolic
compounds, while the aqueous decoction of the recipe 3 of adult has the strongest content of this compound in
adult. Besides the recipes 2 of the child and 1 of adult, the aqueous extracts of our recipes are richer in total
polyphenols than hydroethanolics macerated. These results are consistent with those of Petko and al. [26]
which
show that the extraction rate increases with temperature as well as the team of Agbangnan[27]
which showed that
the increase in temperature has a positive effect on the extraction of phenolics compounds. In general, the
phenolic compound content of the dry extracts not only vary from one plant to another from the same family but
also a function of the solid-liquid extraction parameters: the temperature, the extraction solvent, the particle size
and solvent diffusion coefficient.

The evaluation of the anti-radical property of our extracts shows that the extracts possess constituents
which discolor the solution of DPPH. The antioxidant activity of each of the extracts on the free radical DPPH is
expressed in substrate concentration which inhibits by 50% the activity of DPPH (IC50). The antioxidant
capacity of an extract is considerable when its IC50 is low. From the results obtained and as shown in the figure
above, aqueous extract recipes 3 (0.090 mg/mL), 1 (0.150 mg/mL) and 4 (0.160 mg/mL) of the child have been
very effective with regard to trapping DPPH compared to other extracts and reference antioxidants (quercetin:
0.100 mg/mL; Butylated hydroxyanisole, BHA: 0.090 mg/mL) used in this study. By referring to the contents of
phenolic compounds of our extracts, we observe a correlation between their phenolic content and antioxidant
activity especially only three extracts which have the highest total polyphenol content showed best activity.
These observations corroborate those already made earlier by Chevalley in 2000[28]
; Djeridane et al., 2006[29]
and Wojdylo et al., 2007[30]
.
IV. Conclusion
This work was devoted to the identification of major chemical groups, dosing of phenolic compounds
followed by the evaluation of anti-radical activity of 12 recipes of plants used by the population of lacustrine
cities in southern Benin for the treatment of malaria. Aqueous extracts obtained by decoction of recipes 1, 3 and
4 of the child which are richer in phenolic compounds, also presented the most interesting anti-radical activity.
This work thus makes a significant contribution regarding of knowledge of phytochemical studied receipts and
thus enables a better understanding of the pharmacodynamic properties of extracts explaining their use in
traditional pharmacopoeia.
