A thermosetting polymer, also known as a thermoset, is polymer material that irreversibly cures. The cure may be done through heat through a chemical reaction or irradiation such as electron beam processing. Thermoset materials are usually liquid or malleable prior to curing and designed to be molded into their final form, or used as adhesives. Others are solids like that of the molding compound used in semiconductors and integrated circuits (IC). Once hardened a thermoset resin cannot be reheated and melted back to a liquid form.

polymer science
Polymer science concerns large molecules called polymers that include rubbers, plastics, and fibers. Polymers are made of repeating molecular units and have high molecular weights. There are over 60,000 scientists working with polymers today to develop new materials with customized properties. Common polymers include polypropylene, polyethylene, and nylons. Polymers can be categorized based on their molecular structure as thermoplastics, thermosets, or elastomers, which determine how they respond to heat.
MSE Unit No-03.pptx
Polymers are large molecules composed of many repeating structural units called monomers. There are two main types of polymers - thermoplastics and thermosets. Thermoplastics soften when heated and harden when cooled, while thermosets harden permanently when heated. Common polymerization techniques include bulk, solution, suspension, and emulsion. Engineering polymers are used in automotive and consumer products due to their strength, low cost, and corrosion resistance.
Ceramics are inorganic compounds composed of metallic and non-metallic elements bonded ionically. Common ceramic structures include rock salt, cesium chloride, calcium fluoride, and perovskite. Key properties of ceramics include hardness, brittleness,

omparative historical research is a method of social science that e.pdf
omparative historical research is a method of social science that examines historical events in
order to create explanations that are valid beyond a particular time and place, either by direct
comparison to other historical events, theory building, or reference to the present
day.[1]Generally, it involves comparisons of social processes across times and places. It overlaps
with historical sociology. While the disciplines ofhistory and sociology have always been
connected, they have connected in different ways at different times (see \'Major researchers\'
below). This form of research may use any of several theoretical orientations. It is distinguished
by the types of questions it asks, not the theoretical framework it employs (see \'Illustrations\'
below)
Some commentators have identified three waves of historical comparative research.[2] The first
wave of historical comparative research concerned how societies came to be modern, i.e. based
on individual and rational action, with exact definitions varying widely. Some of the major
researchers in this mode were Alexis de Tocqueville,[3]Karl Marx,[4]Emile Durkheim,[5]Max
Weber,[6] and W.E.B. Du Bois.[7] The second wave reacted to a perceived ahistorical body of
theory and sought to show how social systems were not static, but developed over time.[8]
Notable authors of this wave include Barrington Moore, Jr.,[9]Theda Skocpol,[10]Charles
Tilly,[11]Michael Mann,[12] and Mark Gould.[13] Some have placed the Annales school and
Pierre Bourdieu in this general group, despite their stylistic differences.[14] The current wave of
historical comparative research sociology is often but not exclusively post-structural in its
theoretical orientation. Influential current authors include Julia Adams,[15] Anne Laura
Stoler,[16]Philip Gorski,[17] and James Mahoney.[18]
There are four major methods that researchers use to collect historical data. These are archival
data, secondary sources, running records, and recollections. The archival data, or primary
sources, are typically the resources that researchers rely most heavily on. Archival data includes
official documents and other items that would be found in archives, museums, etc. Secondary
sources are the works of other historians who have written history. Running records are ongoing
series of statistical or other sorts of data, such as census data, ship\'s registries, property deeds,
etc. Finally recollections include sources such as autobiographies, memoirs or diaries.[19]
There are four stages, as discussed by Schutt, to systematic qualitative comparative historical
studies: (1) develop the premise of the investigation, identifying events, concepts, etc., that may
explain the phenomena; (2) choose the case(s) (location- nation, region) to examine; (3) use what
Theda Skocpol has termed as \"interpretive historical sociology\" and examine the similarities
and the differences; and (4) based on the information gathered, propose a causal explanation for
the pheno.

Lewis Acid Base Reaction .pdf
Lewis acid-base reactions involve the sharing of electron pairs between reactants. A Lewis acid is an electron pair acceptor that has an empty orbital, while a Lewis base is an electron pair donor that has a lone pair of electrons. When a Lewis acid and base interact, the base donates an electron pair to form a new bond with the empty orbital on the acid.

fluorene is mobile phase and fluorenone is statio.pdf
fluorene is mobile phase and fluorenone is stationary phase because : Mostly,it
depends on the solvent you are using, but lets assume you use pentane as the solvent for fluorene
and diethyl ether as the solvent for fluorenone. Used in this order, fluorene should actaully move
slower down the column due to the the polarity of the alumina and the nonpolarity of the solvent
(pentane). Since fluorene is less polar so, remember the rule like dissolves like? Well, this kind
of applies to chromatography wherein rather than dissolve just replace it with moves with, so like
moves with like. That being said the pentane will \"carry\" the fluorene through the alumina
slower than the latter (which I will explain). Fluorenone is polar because of its C=O bond, that
being said the dielectric constant of diethyl ether is 4.3 which means it has intermediate polarity
(remember that pentane has a dielectric constant of 2.1 I think, so it is nonpolar). Since the
alumina, diethyl ether, and the fluorenone are all polar, the fluorenone will travel faster through
the alumina than would the fluorene, because there is no attraction between all these polar
compounds which will allow it to move faster, rather than a nonpolar and polar chemical having
an attration towards each other and thus moving more slowly.

d. 8 The bonding electrons are the electrons taki.pdf
The document discusses the bonding electrons in a carbon dioxide (CO2) molecule. Carbon is centered between two hydrogen atoms and one oxygen atom. Carbon shares two electrons with each hydrogen atom, for a total of four electrons shared with hydrogen. Carbon also shares four electrons with the oxygen atom. Therefore, the total number of bonding electrons is the four shared with hydrogen plus the four shared with oxygen, which is eight.

phylogenetic tree in different geographical locations elicit the human origins. The mitochondrial
DNA sequences of Neanderthals and modern humans were compared and analyzed. The
Hominins species were found to be 30000 year old and were compared with Neanderthal
specimens.
The relationships between these populations have drawn with the help of the age of specimens
plotted against the average genetic distance. The Hominins type sequences are very rare when
compared with the modern European samples. The prehistoric Europeans had shown constant
number of differences when compared to today’s Europeans and Neanderthals.
The Neanderthals have shown the genetic continuity in modern human’s genealogy. The
Neanderthals had shown clear discontinuity with the Hominins from upper Paleolithic period to
the similar ages. The Neanderthals and early anatomical modern humans were thought to be
regional populations of the same evolving species connected by gene flow and both the archaic
and modern humans contribute in different proportions to the present human gene pool.
The transition and demographic replacement separated the population as Neanderthals and
modern humans are considered just as one population observed at different times. The multi
regional models predict that at least some level of genetic continuity can be observed from
archaic Neanderthal forms to the contemporary Hominins forms and up to today’s Europeans.
The results have not matched with the view that the Neanderthal were genetically related with
the anatomically modern ancestors of current Europeans or contributed to the present day human
gene pool.

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.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

A thermosetting polymer, also known as a thermose.pdf
- 1. A thermosetting polymer, also known as a thermoset, is polymer material that irreversibly cures. The cure may be done through heat through a chemical reaction or irradiation such as electron beam processing. Thermoset materials are usually liquid or malleable prior to curing and designed to be molded into their final form, or used as adhesives. Others are solids like that of the molding compound used in semiconductors and integrated circuits (IC). Once hardened a thermoset resin cannot be reheated and melted back to a liquid form.
