Helen keller achieved success altough she is disabled
Helen Keller achieved success despite being disabled. She became blind and deaf at a young age after becoming sick. In 1887 she met her teacher Anne Sullivan who patiently taught her how to communicate by feeling things with her hands and speaking. Helen Keller went on to write many books and showed the world that blind people can accomplish great things. She passed away in 1968 but is still admired worldwide for overcoming her disabilities.
To evaluate antimicrobial activity of different soil bacteria
This document describes evaluating the antimicrobial activity of different soil bacteria isolated from five soil samples in Ludhiana, India. The soil samples were collected, diluted in water to make suspensions, and plated to isolate bacteria. Colonies showing clear zones of inhibition, where growth of other organisms was retarded, were observed. This inhibition was likely due to the production of substances like organic acids, toxins, or antibiotics by the bacteria. The goal was to determine which soil bacteria exhibited antimicrobial activity.
Research history of sex
Early understandings of human sexuality developed from observing animal behavior. Aristotle established a foundation for Western sexology by classifying reproduction. Plato believed the uterus caused hysteria in women. The 1600s saw advances in understanding female anatomy but misunderstandings remained. The microscope helped identify sperm and compare healthy and unhealthy men. Debates emerged around sexuality within marriage and views of women's sexuality. Early sex researchers studied a wide range of topics from sexual practices to homosexuality to female sexual response. Their work helped establish the modern field of sexology.
Nazism and rise of hitler(goel & company ludhiana)
Adolf Hitler rose to power in Germany in the early 1920s by joining and becoming a prominent member of the Deutsche Arbeiterpartei, later renamed the Nazi Party. The party was opposed to the democratic Weimar Republic and advocated for extreme nationalism, anti-Semitism, and Pan-Germanism. Hitler utilized public speaking and some violence to increase his influence within the party. In January 1933, Hindenburg appointed Hitler as chancellor of Germany in a coalition government, giving the Nazis increased political power. In March 1933, the Reichstag passed the Enabling Act, granting Hitler dictatorial powers and eliminating political opposition.

Adolf hitler(by chetan kumar goel ludhiana)
Hitler was born in 1889 in Austria and spent his youth in poverty. In 1919, he joined the German Workers' Party and renamed it the National Socialist Party, known as the Nazi Party. During the economic crisis, the Nazi Party gained popularity by promising to build a strong nation, undo the injustices of the Treaty of Versailles, and restore German dignity. Hitler suspended civil rights, sent opponents to concentration camps, and banned all political parties except the Nazi Party to establish total control over Germany. After Germany's defeat in World War II, Hitler committed suicide.

biodegradable polymers
1) Biodegradable polymers are polymers that break down into smaller molecules through mechanisms such as hydrolysis or enzymatic degradation. They include both synthetic polymers like polylactic acid, polyglycolic acid, and polycaprolactone, as well as natural polymers like collagen and albumin.
2) The degradation of biodegradable polymers can occur through either surface or bulk erosion and can be mediated by water, enzymes, or microorganisms. Common mechanisms include cleavage of crosslinks, transformation of side chains, or cleavage of the polymer backbone.
3) Biodegradable polymers find applications as drug delivery systems where they provide localized and sustained release of drugs as well as reduce dosing frequency
Fundamentals of polymer chemistry
Polymer:
A large molecule having high molecular mass formed by joining a repeating unit of smaller molecules (monomers) through a covalent bonding is called as polymer. Monomer is small individual repeating unit or molecules are called monomers. Monomer is basic unit of polymer. E.g. In polyethylene is an ethylene is monomer. Polymers usually contain more than five monomers, and some may contain hundreds or thousands of monomers in each chain. The process by which polymers are formed by linking monomers through chemical reaction called polymerization.
1. Physical Properties: The molecular weight of a polymer molecule is the product of the degree of polymerization and the molecular weight of the repeating unit. The polymer molecules are not identical but are a mixture of many species with different degrees of polymerization, that is, with different molecular weights. Therefore, in the case of polymers we talk about the average values of molecular weights.Polymerization reactions produce a distribution of molecular weights and shapes. Polymer molecular weight could be expressed as number average molecular weight, weight average molecular weight, and polydispersity.
The polymer chains being very large hence found in the two polymeric forms. Crystalline Polymers:
Lamellar crystalline form in which the chains fold and make lamellar structure arranged in the regular manner. Amorphous Polymers: Amorphous form in which the chains are in the irregular manner.A typical range of crystallinity can be defined as amorphous to highly crystalline. The polymers having simple structural chains as linear chains and slow cooling rate will result in good crystallinity as expected.
02. Thermal Properties:
a)Polymer Glass Transition temperature:
In the study of polymers and their applications, it is important to understand the concept of the glass transition temperature, Tg. As the temperature of a polymer drops below Tg, it behaves in an increasingly brittle manner. As the temperature rises above the Tg, the polymer becomes more rubberlike. Thus, knowledge of Tg is essential in the selection of materials for various applications. In general, values of Tg well below room temperature define the domain of elastomers and values above room temperature define rigid, structural polymers.
The objective of polymer synthesis is to efficiently assemble macromolecules with precisely controlled structures, so as to maximize their utility for a given application. Polymerization can occur via a variety of reaction mechanisms that vary in complexity due to the functional groups present in the reactants and their inherent steric effects.There are two major types of' polymerization methods used to convert small molecules (monomers) into polymers. These methods were originally referred to as addition or chain growthpolymerization and condensation or step growth polymerization. The coordination polymerizationis another variant of chain-growth polymerization.

The student cites an example of a company in India that has established a plant to produce diesel fuel from plastic waste.
IRJET - Fuel from Plastic Waste
This document summarizes a study on converting plastic waste into fuel through pyrolysis. Plastic production has increased pollution as most plastics are not biodegradable. Pyrolysis, the thermal decomposition of plastics at high temperatures, was used to break down plastic polymers into hydrocarbon fuels like petrol, kerosene and diesel. Low density polyethylene plastic waste was pyrolyzed in a reactor at 300°C. The resulting plastic fuel was filtered, purified and tested. Testing showed the plastic fuel had properties similar to diesel, including color, density, viscosity and calorific value. While plastic fuel production addresses waste and fuels, drawbacks include safety, odor and respiratory issues. The study concludes pyrolysis is an effective way to

Polymeric materials, commonly known as polymers, are composed of repeating structural units called monomers that are linked together to form large, complex molecules. These materials are widely used in modern society due to their versatility, ease of processing, and desirable properties. Polymers have applications across many industries, from packaging and textiles to electronics and medicine, because of their ability to be tailored for specific uses.
Fuel from plastic waste
This document discusses converting plastic waste into fuel. It aims to solve the twin problems of plastic pollution and the need for alternative fuel sources. Plastic waste would be converted into valuable fuel through processes like pyrolysis and gasification. These processes involve heating plastic in the absence of oxygen to produce liquid and gas fuels. Converting plastic waste to fuel is proposed as an environmentally friendly solution that generates profit while reducing plastic in landfills and the problems they cause.
APPLICATIONS OF PLA - POLY (LACTIC ACID) IN TISSUE ENGINEERING AND DELIVERY S...
Poly (lactic acid) is a thermoplastic derived from renewable resources and is at present, one of the most promising biodegradable and nontoxic biopolymers. In addition to its versatility and consequent large-scale production, PLA can be processed with a large number of techniques.
Due to its excellent mechanical properties and biocompatibility, this polymer is becoming largely applied in the biomedical field such as in tissue engineering for scaffolds and in delivery systems in the form of micro and nanoparticles. Furthermore, because it’s relatively cheap and an eco-friend, it has been considered as one of the solutions to lessen the dependence on petroleum-based plastics and solid waste problems.
In order to maximize the knowledge and development of this polymer, it is necessary to understand the material synthesis, proprieties, manufacturing processes, main applications, commercialization and its market state, which will be presented in this review.

This document discusses using water-soluble extracts (WSE) obtained from banana pseudo-stems as additives blended with polylactic acid (PLA) to improve its properties. WSE were characterized and blended with PLA using various techniques. Thermal and mechanical properties of PLA/WSE blends were investigated using different methods. Results showed that WSE acted as a plasticizer for PLA and positively impacted its crystallization, stiffness, and strain-hardening properties while having a detrimental effect on brittleness. These findings suggest the potential of using such agricultural by-products as sustainable additives for polymer applications.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems
9
Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
