1. The document discusses the conformations of decalin, a fused bicyclic hydrocarbon. Decalin can exist in two conformations - cis and trans.
2. The trans conformation is more stable than the cis conformation by 2.7 kcal/mol. This is because the cis conformation contains unfavorable nonbonded interactions and three gauche interactions between hydrogen atoms.

Reaction intermediates
Reaction intermediates such as carbocation, carbanion, free radicals, carbene, nitrene and ylides were discussed.
Asymmetric synthesis
Asymmetric synthesis is a chemical reaction that produces one stereoisomer in greater amounts than the other. It is achieved through the use of a chiral feature like a substrate, reagent, catalyst, or environment that favors the formation of one enantiomer over the other in the transition state. Some common approaches for asymmetric synthesis include using a chiral starting material from nature, attaching a chiral auxiliary, or employing a chiral reagent or catalyst. The separation and analysis of enantiomers can be challenging given their identical physical properties, requiring techniques like chiral chromatography or crystallization. Asymmetric synthesis has important applications in pharmaceuticals for producing drugs that are safer and more effective.

It can also undergo ring cleavage to form monosubstituted hydrazines.
organomagnesium-compounds.ppt
The document discusses organomagnesium halides (Grignard reagents). It describes how Grignard reagents are useful synthetic intermediates for carbon-carbon bond formation and are sources of nucleophilic carbanions.

It also discusses the mechanisms and applications of important Grignard reactions such as the Bouveault, Benary, Bodrous, Dzhemilev and Kulinkovich reactions.
Radical retrosynthesis
1) Radical retrosynthesis uses one-electron disconnections to simplify synthesis, avoiding protecting groups, functional group interconversions, and redox steps. This enables more direct and minimal syntheses.
2) Radical cross-coupling reactions allow forming C-C and C-X bonds through hydrogen atom transfer or coupling of radicals with redox-active esters, sulfones, or other species. This provides unique chemoselectivity advantages over polar pathways.
3) Case studies demonstrate strategic benefits of radical cross-coupling for synthesis ideality, efficiency, selectivity, and modularity by opening new retrosynthetic opportunities not accessible through two-electron analysis.

Asymmetric Synthesis - Christeena Shaji
This document discusses asymmetric synthesis, which produces unequal amounts of stereoisomers from achiral precursors. It can be enantioselective or diastereoselective. There are two types: partial asymmetric synthesis, which forms a new chiral center from an achiral precursor using a chiral substrate, auxiliary, reagent, or catalyst; and absolute asymmetric synthesis, which uses no chiral precursors but instead relies on physical chirality like circularly polarized light. Common approaches include using a chiral pool substrate, chiral auxiliary, chiral reagent, or chiral catalyst. The mechanisms and examples of various methods are explained in detail.

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

THEMATIC APPERCEPTION TEST(TAT) cognitive abilities, creativity, and critic...Abdul Wali Khan University Mardan,kP,Pakistan
hematic appreciation test is a psychological assessment tool used to measure an individual's appreciation and understanding of specific themes or topics. This test helps to evaluate an individual's ability to connect different ideas and concepts within a given theme, as well as their overall comprehension and interpretation skills. The results of the test can provide valuable insights into an individual's cognitive abilities, creativity, and critical thinking skillsApplied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
Equivariant neural networks and representation theory
Or: Beyond linear.
Abstract: Equivariant neural networks are neural networks that incorporate symmetries. The nonlinear activation functions in these networks result in interesting nonlinear equivariant maps between simple representations, and motivate the key player of this talk: piecewise linear representation theory.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
