The document concludes with activities to practice writing complementary RNA sequences and determining amino acid sequences from DNA codons.
Applications of electromagnetic spectrum.pptx
The document discusses applications of the electromagnetic spectrum and describes how radio waves are used in telecommunications. It aims to cite examples of how different regions of the EM spectrum are used practically, such as using radio waves for telecommunications, and to describe how radio waves are generated, transmitted and received by naming the parts of radio transmitters and receivers and their functions.
BOUNDARY.pptx
The document describes the three main types of plate boundaries: convergent boundaries, divergent boundaries, and transform boundaries. It states that convergent boundaries occur when tectonic plates move toward each other and collide, and can be oceanic-oceanic, oceanic-continental, or continental-continental. Divergent boundaries occur when plates move away from each other, forming constructive boundaries. Transform boundaries form when plates slide past each other, producing earthquakes.
A_Seaweed_Divided_0.ppt
This document discusses different types of seaweed (macroalgae) including red, green, and brown algae. It provides details on their classification, structure, where they are found, and their economic importance. It notes that seaweeds are not plants but are divided into three major groups based on pigmentation. While seaweeds provide numerous benefits like food and oxygen production, increased eutrophication and salinity changes in the Baltic Sea are allowing a less beneficial type of seaweed to spread, threatening the ecosystem.
2018_12_5_coralspost (1).pptx
Coastal ecosystems like coral reefs have high productivity and biodiversity due to dynamic spatial gradients in factors like salinity, temperature, light, and nutrients. Coral reefs specifically proliferate in warm, shallow, saline waters. Corals are colonial animals whose polyps secrete calcium carbonate to form hard structures over time. Corals have a symbiotic relationship with algae called zooxanthellae, which provide nutrients through photosynthesis. Corals reproduce both asexually through fragmentation and sexually through broadcast spawning or brooding.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
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 skillsThe debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

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.

Applied 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.

- 5. Biomolecules • Molecules are either inorganic compounds or organic compounds – Organic-has carbon – Inorganic-no carbon • Why is carbon so special? – It can form 4 bonds with other atoms. It loves to COVALENTLY BOND! – It can form single, double, and triple bonds.
- 6. Biomolecules • There are 4 types of biomolecules in our bodies – Carbohydrates – Lipids (fats) – Proteins – Nucleic acid (DNA) • These are large molecules (polymer) that are made up of smaller building blocks (monomers) • Polymers are made of monomers. • http://www.phschool.com/scie nce/biology_place/biocoach/bi oprop/monomers.html
- 7. Proteins • Elements: C, H, O, N, or S (sulfur) • Structure: look for N or S • What do they do – Hemoglobin in your blood that carries oxygen – Muscles, tendons, hair – Defend body from microorganisms – Control chemical reactions-enzymes – Carry out almost all of the body’s everyday functions • Building block-amino acids
- 8. Proteins • A protein’s shape is very important • You change the shape of a protein, you change the function or lose the function
- 9. Testing for proteins • You will use a biuret reagent • It will turn a blue violet color in the presence of a protein. • You will add each substance to a test tube and then add a few drops of biuret reagent.
- 10. Carbohydrates • Elements-C, H, O • Function: Main source of energy, gives plants tough structure • Examples: sugars and starches, glycogen, sucrose, glucose, cellulose • Shape-rings connected • Building Block- monosaccharide or simple sugars (glucose)
