UV-visible spectroscopy involves using light in the UV-visible spectral region to analyze chemical substances. It works on the principle of Beer-Lambert's law, where absorbance is directly proportional to concentration and path length. Different functional groups and conjugated systems can absorb light at characteristic wavelengths. The technique is used for quantitative and qualitative analysis of samples through measurement of absorption spectra. It provides information about electronic transitions and molecular structure of compounds.

Chromophores are groups responsible for light absorption, such as C=O, C=N. Auxochromes attached to chromophores alter the wavelength and intensity of absorption. There are four types of shifts in absorption that auxochromes can cause: 1) Bathochromic shift - Absorption shifts to longer wavelengths, such as from decreased solvent polarity or increased conjugation. 2) Hypsochromic shift - Absorption shifts to shorter wavelengths, such as from increased solvent polarity, removal of conjugation, or auxochrome substitution. 3) Hyperchromic shift - Absorption intensity increases, such as from alkyl substitution. 4) Hypochromic shift - Absor

UV/visible spectroscopy involves measuring the absorption of ultraviolet or visible light by molecules. It utilizes light in the wavelength range of 200-800 nm. The key components of a UV-visible spectrophotometer are a light source, wavelength selector such as a monochromator, sample holder, detector, and associated electronics. Common light sources include deuterium lamps, tungsten lamps, and mercury lamps. Samples are typically held in quartz or glass cuvettes. Detectors include phototubes and photodiodes. UV-visible spectroscopy can be used to analyze samples containing multiple components. Methods for multicomponent analysis include simultaneous equations using absorption data at two wavelengths, absorbance ratio methods

Infrared spectroscopyShabnamkhan113

��

Infrared spectroscopy involves the interaction of infrared radiation with matter. Molecules absorb specific frequencies that excite vibrational modes. The absorbed frequencies are characteristic of bonds and functional groups within a molecule. Fourier transform infrared spectroscopy (FTIR) has advantages over dispersive instruments as it allows simultaneous measurement of all frequencies using an interferometer. Applications in forensics include identification of materials like paint, fingerprints, and detection of document alterations or counterfeit substances.

Effect of solventDr. Mahendra GS

��

The document discusses how solvents and chromophores affect UV-visible spectroscopy. It states that the solvent exerts influence on the absorption spectrum, with the same drug showing different absorption maxima in different solvents. Common solvents used are water, methanol, ethanol, ether, and cyclohexane. The solvent should not absorb in the region studied and have minimum interaction with solute. Chromophores like conjugated systems, carbonyls, and metal complexes determine absorption. Factors like conjugation, auxochromes, and solvent polarity can shift absorption maxima.

UV-Visible spectroscopy involves absorption of ultraviolet or visible light by molecules. This absorption causes electrons to move to higher energy molecular orbitals. The Beer-Lambert law states that absorbance is directly proportional to concentration and path length. Deviations from Beer-Lambert law can occur at high concentrations due to interactions between molecules, or if non-monochromatic light is used. UV-Visible spectroscopy is used to study electronic transitions and structure of molecules.

Ultraviolet-visible (UV-Vis) spectrophotometry is a technique used to measure light absorbance across the ultraviolet and visible ranges of the electromagnetic spectrum. When incident light strikes matter it can either be absorbed, reflected, or transmitted. The absorbance of radiation in the UV-Vis range causes atomic excitation, which refers to the transition of molecules from a low-energy ground state to an excited state.

Deviations from Beers lawVrushali Tambe

��

This document discusses various deviations from Beer's Law that can occur when using UV-Vis spectroscopy. There are three main types of deviations: 1) True deviations due to high analyte concentrations that cause interactions between molecules and changes in optical properties. 2) Instrumental deviations caused by factors like use of polychromatic light, improper slit width, stray light, mismatched cells, and scanning speed. 3) Chemical deviations due to shifts in chemical equilibria with changing concentration, like for pH indicators. Nonlinearity can be minimized by optimizing factors like concentration, slit width, and wavelength range used.

Scientific Pig Farming Manual for Pig FarmersDr. Subhrajit Das

��

Pig farming, pork farming, pig production or hog farming is the raising and breeding of domestic pigs as livestock, and is a branch of animal husbandry. Pigs are farmed principally for food (e.g. pork: bacon, ham, gammon) and skins. Pigs are amenable to many different styles of farming: intensive commercial units, commercial free range enterprises, or extensive farming (being allowed to wander around a village, town or city, or tethered in a simple shelter or kept in a pen outside the owner's house). Historically, farm pigs were kept in small numbers and were closely associated with the residence of the owner, or in the same village or town.[1] They were valued as a source of meat and fat, and for their ability to convert inedible food into meat and manure, and were often fed household food waste when kept on a homestead.[2] Pigs have been farmed to dispose of municipal garbage on a large scale.[3] All these forms of pig farm are in use today, though intensive farms are by far the most popular, due to their potential to raise a large amount of pigs in a very cost-efficient manner.[4] In developed nations, commercial farms house thousands of pigs in climate-controlled buildings.[5] Pigs are a popular form of livestock, with more than one billion pigs butchered each year worldwide, 100 million in the United States. The majority of pigs are used for human food, but also supply skin, fat and other materials for use in clothing, ingredients for processed foods,[6] cosmetics,[7] and medical use.[8]Pig farming has gained importance today. Pigs have inherited capacity to acclimatize with varying climatic conditions. Pigs cannot withstand high temperature climate. Pigs are adjusted to varied rearing practices and consume different types of food (Omnivorous) to attain higher growth and meat production. Pigs will attain 60-70kg body weight in 6-8months period. Female pigs i.e., sows will come to heat at age of 8-9 months but avoid using male pigs (Boars) for breeding purpose until it attains one year of age. Adult sows when bred during right time after attaining maturity will farrow 8-12 piglets in 112-118 days of gestation period (i.e., about 4 months of gestation). Feedefficiencyis to gain one Kg live weightfor every 2.75-3kg feed consumed (FCR: 1:2.75). There are many advantageous in pig rearing. Pork is available at a cheaper price with nutritious and highly palatable tasty meat of higher quality animal protein. Pig bones are used for producing bone meal and also used for purification of sugar in sugar industry. The manure droppings and urine are good fertilizers which enhance the soil fertilityand improve grain production. Pig hairs (Bristles) are used for making brushes and ropes, hooves are used for shirt button making and preparation of gum. Hence, pigs are called as “multi utility domestic animals”. Farmers can take up piggery farming and reduce their debt burden and improve their profits and livelihood.

Beyond Point Masses. IV. Trans-Neptunian Object Altjira Is Likely a Hierarchi...Sérgio Sacani

��

Dynamically studying trans-Neptunian object (TNO) binaries allows us to measure masses and orbits. Most of the known objects appear to have only two components, except (47171) Lempo, which is the single known hierarchical triple system with three similar-mass components. Though hundreds of TNOs have been imaged with high-resolution telescopes, no other hierarchical triples (or trinaries) have been found among solar system small bodies, even though they are predicted in planetesimal formation models such as gravitational collapse after the streaming instability. By going beyond the point-mass assumption and modeling TNO orbits as non-Keplerian, we open a new window into the shapes and spins of the components, including the possible presence of unresolved “inner” binaries. Here we present evidence for a new hierarchical triple, (148780) Altjira (2001 UQ18), based on non-Keplerian dynamical modeling of the two observed components. We incorporate two recent Hubble Space Telescope observations, leading to a 17 yr observational baseline. We present a new open-source Bayesian pointspread function fitting code called nPSF that provides precise relative astrometry and uncertainties for single images. Our non-Keplerian analysis measures a statistically significant (∼2.5σ) nonspherical shape for Altjira. The measured J2 is best explained as an unresolved inner binary, and an example hierarchical triple model gives the best fit to the observed astrometry. Using an updated non-Keplerian ephemeris (which is significantly different from the Keplerian predictions), we show that the predicted mutual event season for Altjira has already begun, with several excellent opportunities for observations through ∼2030.

Unjustly Incriminating Bacteria: the Role of Bacteriophages in Bacterial Infe...christianagboeze2427

��

SUMMARY Based on human relationship with bacteria, virulence is one of the most important case to us. Some forms of virulence thought to arise only from the actions of bacteria are not actually caused by them but are indirectly influenced by another counterpart in the microbial mix of the ecosystem called bacteriophage; viruses that only infect prokaryotes such as bacteria but not eukaryotes. Bacteriophages preferably attack bacteria due to the lack of specific receptors for phages on eukaryotic cells which are found in bacteria e.g. peptide sequences and polysaccharide moieties in gram positive and gram negative bacteria, bacterial capsules, slime layers, flagella etc. They recognize and bind to bacteria using appropriate receptors, subsequently proceeding to inject their genome called prophage into their host. This review focuses on the most probable outcomes of phage-host interactions via the lytic and lysogenic cycles which are therapeutic effect and pathogenicity/resistance to antibiotics respectively. By lysogenic conversion or transfer of acquired genetic materials via transduction, phages can confer unusual traits such as virulence and antibiotics resistance. Important pathogenic bacteria that cause persistent and critical infections which have their pathogenicity engineered by phages include Pseudomonas aeruginosa, Salmonella enterica, Escherichia coli, Vibrio cholerae, Staphylococcus spp., and Clostridium spp. The prophages influence their virulence in a variety of ways which include: contribution to the production of phage-encoded toxins, modification of the bacterial envelope, mediation of bacterial infectivity, and control of bacterial cell regulation. The unwavering threat of antimicrobial resistance in global health, extreme difficulty involved in developing novel antibiotics, and the rate at which microorganisms develop resistance to newly introduced antimicrobials have sparked urgency and interest in research for effective methods to eradicate pathogenic bacteria and limit antibiotic resistance. As a result, interest in phage therapy has been reignited because of the high efficiency in detecting and killing pathogenic bacteria by phages.

��

How could modern LA research address data-related ethics issues in informal and situated professional learning? I will identify in this talk three relevant insights based on field studies around workplace LA interventions: Firstly, in informal and situated learning, data isn’t just about the learners. Secondly, the affordances of manual and automatic data tracking for learning are very different, with manual tracking allowing a high degree of learner control over data. Thirdly, learning is not necessarily a shared goal in workplaces. These can be translated into seeing a potential for systems endowed with sufficient natural-language-processing capability (now seemingly at our fingertips with LLMs), and socio-technical design and scenario-based data collection analysis as design and research methods.

Detection of ferrihydrite in Martian red dust records ancient cold and wet co...Sérgio Sacani

��

Iron oxide-hydroxide minerals in Martian dust provide crucial insights into Mars’ past climate and habitability. Previous studies attributed Mars’ red color to anhydrous hematite formed through recent weathering. Here, we show that poorly crystalline ferrihydrite (Fe5O8H · nH2O) is the dominant iron oxidebearing phase in Martian dust, based on combined analyses of orbital, in-situ, and laboratory visible near-infrared spectra. Spectroscopic analyses indicate that a hyperfine mixture of ferrihydrite, basalt and sulfate best matches Martian dust observations. Through laboratory experiments and kinetic calculations, we demonstrate that ferrihydrite remains stable under present-day Martian conditions, preserving its poorly crystalline structure. The persistence of ferrihydrite suggests it formed during a cold, wet period on early Mars under oxidative conditions, followed by a transition to the current hyper-arid environment. This finding challenges previous models of continuous dry oxidation and indicates that ancient Mars experienced aqueous alteration before transitioning to its current desert state.
