Vacuum centrifuge/concentrators
A vacuum centrifuge concentrator uses centrifugal force and low pressure to evaporate liquids from samples and concentrate biomolecules like DNA, RNA, and proteins. By spinning samples in a vacuum chamber, it avoids heat buildup issues caused by air resistance in normal centrifuges. This allows for higher spin speeds with less energy. Vacuum centrifuges concentrate samples into dry pellets or wet residues for further analysis and are used in applications like proteomics, genomics, and drug development.

Separation techniques - introduction
Separation techniques are those techniques that can be used to separate two different states of matter such as liquids and solids.
Separation is an important asset to purify component of interest from a mixture.
separationtechniques-introduction-190810143855.pdf
Separation techniques are used to separate mixtures into individual components. Some common separation techniques include distillation, crystallization, chromatography, filtration, centrifugation, and magnetic separation. Distillation uses boiling point differences to separate liquid mixtures through heating and condensation. Crystallization separates dissolved solids from liquids by controlling temperature during solvent evaporation. Chromatography separates mixtures based on how components interact with stationary and mobile phases.
Isolation cell organelle by ankit
Isolation of organelles is accomplished by cell membrane lysis and density gradient centrifugation to separate organelles from contaminating cellular structures. Intact nuclei and organelles have distinctive sizes in mammalian cells, enabling them to be separated by this method.
Prvn ppt
Centrifugation is a process that uses centrifugal force to separate particles in a solution based on their density. It can be used to sediment particles, isolate cellular components like organelles, and separate molecules and complexes. Different types of centrifuges include low-speed, high-speed, and ultracentrifuges, which separate particles through differential centrifugation or density gradient centrifugation. Analytical centrifugation allows observation of fractionation processes and is used to study macromolecules. Centrifugation has various applications including concentration, separation, isolation of organelles, and separation of blood components or cream from milk.

This report details a field research study identifying viral diseases affecting barley crops in South Korea. RT-PCR tests showed that samples were infected with both Barley yellow dwarf virus-PAS and Hordeum vulgare alphaendornavirus. The high occurrence of viruses during the spring season was likely due to suitable climate conditions for the distribution of viral vectors like aphids. A new endornavirus, named Hordeum vulgare alphaendornavirus Buan, was also identified that was 98% identical to a previously reported endornavirus in Korea. The study helps better understand the impact and prevalence of these viruses in barley crops in the Buan region.

Native electrophoretic techniques ppt.pptx
This document discusses different electrophoresis techniques for analyzing protein-protein interactions, specifically blue-native electrophoresis (BNE), clear native electrophoresis (CNE), and high-resolution clear native electrophoresis (hrCNE). BNE uses Coomassie dye to impart a negative charge on proteins, allowing membrane proteins to migrate toward the anode. CNE uses milder conditions at neutral pH to isolate native membrane protein complexes. hrCNE uses anionic detergent micelles instead of dye. BNE provides the best resolution but CNE is milder and better preserves labile complexes. Two-dimensional native electrophoresis can further resolve complexes into individual components. Together these techniques allow isolation and characterization of both stable and transient

key word -Real time PCR.pptx
Real-time PCR, also known as quantitative real-time PCR, allows for both the amplification and simultaneous quantification of a targeted DNA molecule. It works by detecting the accumulation of a fluorescent signal during each cycle of the PCR reaction. Specifically, it relies on all the components of standard PCR as well as a fluorescent oligonucleotide probe containing reporter and quencher dyes - when the probe binds to the target DNA during amplification, the reporter dye produces a detectable fluorescent signal. This allows for the reaction to be continuously monitored in real time, providing both detection and quantification of the DNA target.
PCR and primer design techniques
The document discusses various techniques and applications of polymerase chain reaction (PCR). It describes the invention of PCR in 1982 and some key adaptations such as real-time PCR, which allows for quantitative analysis of DNA amplification in real time using fluorescent probes. Different types of PCR are also summarized, including reverse transcription PCR, nested PCR, multiplex PCR, and touchdown PCR. Components of real-time PCR and steps in the PCR process are outlined.

The study found that applying chitosan at concentrations of 1, 2, and 3 g/L and chlorocholine chloride at 5, 10, and 15 mg/L significantly increased average plant height, number of leaves, and leaf surface area compared to the control. A two-way ANOVA and Tukey's multiple comparisons test showed highly significant interactions between the factors and differences between the means of most treatment combinations. The column factor of chitosan and chlorocholine chloride treatment had the strongest effect on the results.
PhD; Qualification exam (mesele)2
This document summarizes seven strategies that plant viruses use to translate multiple proteins from a single mRNA, which is necessary because the host cell's translation system normally produces only one protein per mRNA. The strategies described are: 1) having a multipartite genome with multiple RNA segments, 2) producing proteins from a polyprotein via proteolytic cleavage, 3) using subgenomic RNAs, 4) read-through of stop codons to produce extended proteins, 5) leaky scanning of ribosomes, 6) internal initiation of translation, and 7) frameshifting during translation. Examples are provided for many plant viruses that employ each strategy, such as bromoviruses having multipartite genomes and potyviruses expressing via a poly

ANAMOLOUS SECONDARY GROWTH IN DICOT ROOTS.pptx
Abnormal or anomalous secondary growth in plants. It defines secondary growth as an increase in plant girth due to vascular cambium or cork cambium. Anomalous secondary growth does not follow the normal pattern of a single vascular cambium producing xylem internally and phloem externally.
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.
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.

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.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

Nucleophilic Addition of carbonyl compounds.pptx
Nucleophilic addition is the most important reaction of carbonyls. Not just aldehydes and ketones, but also carboxylic acid derivatives in general.
Carbonyls undergo addition reactions with a large range of nucleophiles.
Comparing the relative basicity of the nucleophile and the product is extremely helpful in determining how reversible the addition reaction is. Reactions with Grignards and hydrides are irreversible. Reactions with weak bases like halides and carboxylates generally don’t happen.
Electronic effects (inductive effects, electron donation) have a large impact on reactivity.
Large groups adjacent to the carbonyl will slow the rate of reaction.
Neutral nucleophiles can also add to carbonyls, although their additions are generally slower and more reversible. Acid catalysis is sometimes employed to increase the rate of addition.

The 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.
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.

- 2. CENTRIFUGATION Centrifuge is a device that used to separate various components of fluid. Achieved by spinning the fluid at high speed with in a container, thereby separating fluids of different densities. In biology the particles are usually cells, subcellular organelles, or large molecules. A laboratory centrifuge is a laboratory equipment Driven by motor spine liquid at high speed Separate substance of greater and lesser density
- 3. PRINCIPLE Rate of settling of a particle, or the rate of separation of two immiscible liquids, is increased many times by the application of a centrifugal field (force) many times that of gravity. Works using sedimentation principle, where centripetal acceleration causes denser substances and particle to move outward. Consists of rotor containing two, four, six, or many other numbered walls with in which the sample containing centrifuge tips may be placed.
- 4. BIOSEPARATIONS • Separating and purifying biological materials • Filtration and centrifugation • Chromatography and electrophoresis also common methods
- 5. SUPERNATANT AND A PELLET • Supernatant is the liquid at the top that are less dense are dispel the center • Pellet is particles stuck at the bottom of centrifuge tubes
