Cryopreservation and its application to aquaculture.pptxNarsingh Kashyap
What is Cryopreservation ?
Cryopreservation is a process where biological materials such as cells and tissues are preserved by cooling to very low temperatures, usually at -196°C (the temperature of liquid nitrogen), yet remain viable after later warming to temperatures above 0°C.
Cryopreservation in aquatic species goes back 65 years and began about the same time as similar research was performed in livestock (Blaxter 2011).
In India, NBFGR & CIFA are the primary organization carrying out fish sperm cryopreservation for long term gene banking (J. K. Jena 2012)
Fishes, amphibians, reptiles, and birds have paired pharyngeal ultimobranchial glands that secrete the hypocalcemic hormone calcitonin. The corpuscles of Stannius, unique glandular islets found only in the kidneys of bony fishes, secrete a peptide called hypocalcin.
Fertilized fish eggs are known as Fish seeds. In simple words, they are the baby fishes used for seeding new Ponds in fisheries. Fish seed transportation is a process by which transfer of fish seed from the hatchery or place of collection to the rearing ponds.
A knockout mouse is a mouse in which a specific gene has been inactivated or“knocked out” by replacing it or disrupting it with an artificial piece of DNA.
The loss of gene activity often causes changes in a mouse's phenotype and thus provides valuable information on the function of the gene.

Production and Market of High Fructose Corn Syrup (HFCS) in ChinaMarket_Publishers
China’s HFCS industry has seen a fast growth since 2006, especially after 2009. As the best substitute for
sucrose, HFCS benefits from the continuous price hike of it. The number of new producers is increasing,
and many producers have enlarged their capacity to chase the product's remarkable profit. In this report,
you can find out the latest production situation in China.
Since HFCS is a deep processing product of corn, many producers and downstream consumers are
worried about the government's policies to restrict corn deep processing industry, fearing they will push up
their production cost. In this report we introduce major policies, and analyze their influence on the industry.
Additionally, the latest consumption of HFCS in China is another focus in this report, and we also provide
forecast on it in the coming few years.
High Fructose Corn Syrup (HFCS) Process Plant ProjectAlfonso Figueroa
• Researched and wrote a paper on HFCS about how it is manufactured in processing facilities.
• Characterized how HFCS is manufactured via a flow diagram, gave a capital cost estimate of how much it costs to produce the sweetener, and evaluated a company that manufactures the sugar, American Crystal Sugar Company.

Rainbow Trout: Introduction and Importancemeemail377
Rainbow trout, Oncorhynchus mykiss, are colorful freshwater fish native to North America, renowned for their striking iridescent hues. Sporting a streamlined body and distinctive pink stripe along their sides, rainbow trout inhabit cold, clear streams and lakes. They are prized by anglers for their spirited fights and delicious flesh. Rainbow trout are opportunistic feeders, consuming insects, crustaceans, and small fish. They play crucial roles in freshwater ecosystems as both predators and prey, contributing to the balance of aquatic food webs.

Trends in the geometric size and rated power capacity of offshore wind turbines, the main components of an OWT system, encompassing a typical monopile foundation, the substructure, transition piece, the tower, rotor blades and nacelle (hub). Modern OWTs are installed with either pitch-regulated blades or variable rotational speed systems in order to allow optimisation of the power production over a wide range of prevailing wind speeds. The rotational speed of the main rotor shaft is typically between about 10 and 20 rp. Key electromechanical components of the wind turbine, including the gearbox and the generator (Roberts et al.,2007). The gearbox may cause efficiency losses for the wind turbine and is the particular source of the noise. Recent developments in the design of permanent magnet generators have made it possible to construct some types of wind turbines without the requirement for a gearbox. In this case, the rotor is mainly connected directly to a low-speed multi-pole generator that rotates at the same speed, termed the direct-drive unit. Removing the gearbox mainly removes one of the key components requiring more maintenance, and that is mainly prone to failure. This simplification of the mechanical part allows reductions in size and the mass of the nacelle (Gilling, 2009).
The source of energy captured by plants is the sun, which will be the constant source of energy for the next few billion years. The carbon released from the burning of biofuels is continually cycled rather than being released from the ancient fixed carbon sources, as is the case for fossil petroleum and natural gas. The problem is that the cost of the production of fuels from lignocellulose and plant oils is high and this nascent industry cannot compete with the oil prices. Current progress: For the past two decades, ethanol has been synthesized primarily from cornstarch and cane sugar. Fourteen billion gallons of ethanol were synthesized in the USA from cornstarch in 2014. Approximately 40% of the current USA corn crop is availed to produce ethanol and is not likely to expand anymore, because the remainder of the crop is being availed for animal feed and human food. Ethanol is produced from cane sugar in Brazil at a level of 7.2 billion gallons in the year 2014. The renewable energy source is the major terrain to be considered (Sreeremya, 2019).
Agroforestry has a high potential for simultaneously satisfying three important objectives viz., protecting and also stabilizing the ecosystems; producing a high level of output of economic goods; and improving the income and basic materials to the rural population. It has helped in the rehabilitation of the degraded lands on the one hand and has increased farm productivity on the other. At present, agroforestry meets almost half of the demand for fuelwood, 2/3 of the small timber, approx. 70-80 per cent wood for plywood, 60 per cent raw material for paper pulp and approx. 9-11 per cent of the green fodder requirement of livestock, besides meeting the subsistence needs of the households for food, fruit, fiber, medicine etc.
Human population genetics aims to study the population in terms of the genetic variation. This variation can be quantified by determining the gene frequencies of the alleles at segregating loci which mainly characterize one population and distinguish with another. Tasting ability to phenylthiocarbamide (PTC) by an individual is mainly considered as a useful and important tool to study the genetic diversity in the human populations. Taste and smell affects the food preferences and dietary habits, thereby directly influencing the eating behavior of an individual. As taste threshold aggrandizes with age, abnormality in taste function may contribute to the poor dietary intake in the elderly. Bitter taste perception is a conserved the chemical sense against the ingestion of naturally toxic substances in mammals. The experience of the bitterness occurs after certain chemicals contact taste receptors located in cells on the surface of the tongue.
Initial corrosion behavior of element copper in atmospheric environmentDr. sreeremya S
Copper and copper-based alloys encompassing brasses (Cu-Zn) and bronzes (Cu-Sn)are widely used in different industrial and the societal applications. They are common engineering materials in modern architecture and primarily availed for roofing and facade cladding due to their significance of visual appearance (important from an architectural perspective in terms of the design or during renovation of modern or ancient cultural building), ductility, malleability, the atmospheric corrosion resistance and long-term performance. When exposed to air, the copper forms a brownish-green or greenish blue corrosion layer, often denoted as the patina. Copper patina is commonly known as an aesthetically pleasing surface, and one reason for the extensive use of the copper metal and copper-based alloys in both the ancient and modern architecture. One of the most famous examples is the Statue of Liberty in the harbor of the New York, US.
Bronze alloys are the family of copper-based alloys traditionally alloyed with tin. Bronze alloys are of the exceptional historic interest and still finds wide applications.
These approaches encompass new synthesis and processes as well as new tools for instructing aspiring chemists how to do the chemistry in a more environmentally benign manner. The pros to industry as well as the environment are all a part of the positive impact that Green Chemistry is having in the chemistry community and in the society in general. It is important that chemists develop novel Green Chemistry options even on an incremental basis. While all the elements of the lifecycle of a new chemical or process may not be environmentally benign, it is nonetheless pivotal to improve those stages where improvements can be made. The next phase of assessment can then focus on the elements of the lifecycle that are still in need of the improvement. Even though a new Green Chemistry methodology does not solve at once every problem allied with the lifecycle of a particular chemical or process, the advances that it does make are nonetheless very key. Green Chemistry that mainly possesses the spirit of sustainable development was booming in the 1990s
Electron transfer activity of the photosystem II significantly decreased after the exposure of the Chlorella cells to all the six chemicals availed. Lipid peroxidation was slightly reduced by the antioxidant propyl gallate, not changed by indium nitrate and very potently simulated by diethanolamine, chloroquine, sodium monofluoroacetate and the bromobenzene. For five of the chemicals studied (not bromobenzene) there is the very good correlation between the cytotoxic effects in Chlorella cells measured by the algal growth inhibition test, and also the inhibition of photosystem II activity (Chapman et al., 1991). The results suggest that one very key effect of these chemicals in the Chlorella cells is the inhibition of photosynthetic metabolism by the blocking of the photosystem II functionality.
Corona virus was first identified as the cause of the common cold in 1960. In one study carried out in Canada in 2001, more than 510 patients presented with flu-like symptoms. Virological analyses showed that 3.7% of these cases were positive for the HCoV-NL63 strain by polymerase chain reaction (PCR). Until 2002, the corona virus was considered a relatively simple, nonfatal virus; however, an outbreak in 2002–2003 in the Guangdong province in China, which resulted in spread to many other countries, encompassing Thailand, Vietnam, Taiwan, Hong Kong Singapore, and the United States of America, causes severe acute respiratory syndrome (SARS) and high mortality rates in over 1000 -1100 patients.
In the modern times pollution has become the biggest menace for the survival of the biological species. There are different types of pollution e.g. air, water, soil, sound and mental pollution. Earth was the beautiful landscape but man has ruthlessly exploited for his greed specially, in the last century. With sporadic industrialization and random urbanization environmental pollution has become the serious problem. Over exploitation of open spaces, ever-increasing number of automobiles and the demographic pressure has further aggravated the problem. There are different ways and means to mitigate the urban environmental pollution. Plan-ting of trees and the shrubs for abatement of pollution and improvement of environment is a much effective way and well recognized throughout the world. Earlier, the purpose of planting trees in the urban areas was purely aesthetic (Sheldon et al., 1988a). The incessant increase of urban environmental pollution has necessitated to typically reconsider the whole approach of urban landscaping and its orientation in the order to achieve duel effect i.e. bio-aesthetics and mitigation of pollution.
Relation between haemorrhoids and constipationDr. sreeremya S
Patients frequently complain of bleeding with or without the defecation, a swelling, mild discomfort or irritation. Other symptoms may include soilage or the mucous discharge, pruritis, difficulties with the hygiene, and a sense of incomplete evacuation. Internal hemorrhoids are otherwise painless unless they are mainly thrombosed, prolapsed with edema, or strangulated. External hemorrhoids result in pain when the thrombosis occurs and bleeding if ulceration occurs from pressure necrosis. Skin tags may form from the prior acutely edematous or the thrombosed external haemorrhoids (Johanson et al., 1990
Given the rapid aggrandize, it has been postulated the environment has a key role in the causation of obesity. Factors such as the neighborhood-scale features (referred to as the built environment) have been mainly identified as influencing diet and physical activity (2). Of particular the importance to this framework are features of the food environment (FE), thus constituting barriers and opportunities to food sources of the varying nutritional quality and energy density (3). The FE is delineated as the physical presence of food that can mainly influence a person’s diet (4). Contributing to the FE is the proximity to food store locations such as mainly the restaurants (fast-food, full service, and bars and pubs) and the retail outlets (food markets/grocery stores and liquor stores). Fast- food establishments generally have foods of lower nutritional quality and higher caloric density than the home-prepared foods (3). Early studies have reported fast-food restaurants to be more common in the neighborhoods with a higher prevalence of obesity. However, more recent studies have been melanged,

Although 76-90% of the BMW is non-hazardous and harmless as any of the other municipal waste, the remaining 10-26% is hazardous to humans or animals and deleterious to environment. Inappropriate handling of the BMW may have serious public health consequences and the significant impact on the environment. Major hospitals contribute substantially to the quantum of generation of the BMW. Smaller hospitals, the nursing homes, clinics, the pathological laboratories and blood banks also have major contribution to BMW. The common methods adopted for the BMW disposal are incineration and land filling. However, these methods are mainly considered more expensive and less ecofriendly due to their main negative impact on the environment
Corona virus current scenario (theoretical outlook)Dr. sreeremya S
Corona virus(COVID-19) is RNA virus. Which has proved to be pandemic.It causes respiratory disease called Severe Acute Respiratory Syndrome(SARS). Currently it is a deadly disease which is killing hundreds of people day by day from late 2019 to till date. There is only few studies regarding the corona virus infection in animals. Studies are still progressing to find remedies like variolation, RNA silencing or boosting human interferon’s to decrease the affect of the disease.
INTRODUCTION
As people have seen, the giant industrial wind farms, small household wind turbines, and also everything in between are erecting all over the places. In 2012, the electricity capacity from the wind power in the total electric capacity is about 7.2% in EU, 2.0% in China, and 3.6% in US. Nevertheless, most people agree that wind energy should claim much greater share of the future energy supply. For eg:-, the United States is working on an ambitious target of 21% total electricity capacity by 2030. Indeed, wind energy is one of the fastest growing energy sources today and also in the foreseeable future. However, findings a suitable site to build the wind farm or simply set up the wind turbine is not always easy. The wind must be strong and must be consistent; the tower cannot obstruct the view; and the noise cannot disturb the local residence. Due to the fast growth of the population, it is aggrandizingly difficult to find a suitable place that is proper for a wind turbine yet will not interfere with the people’s everyday life (Srensen et al., 2002).
INTRODUCTION
A lot of basic concepts, technologies and pioneering solutions aiming on very high power densities were mainly developed within the last 20 years. Sometimes this is denoted as the mechatronic system integration or simply as mechatronics. Besides many of the technical aspects, the movings within the value chain represent the great challenge in this process. This is because traditionally defined between electronic device and the power module manufacturers, electronics assemblers, and the metalworking industry will blur or slowly disappear. However, the pressure to go this path increases. If one thinks, e.g., about the hybrid drive as an upgrade option for conventional passenger cars, one is directly faced with the lack of construction space as one of the main serious problems (Alkuhayli et al., 2012).
Pellagra may also occur as the result of a variety of (relatively rare) conditions affecting tryptophan metabolism and as a side-effect of the number of drugs that inhibit tryptophan metabolism. In alcoholics, it is unclear whether pellagra is the result of an impairment of tryptophan and the niacin metabolism directly attributable to alcohol, or whether it reflects general under nutrition among the people who obtain a considerable proportion on their energy needs from alcohol, and hence have the low intake of (nutrient rich) foods(Goldberger et al.,1922a).
SYMPTOMS
The major symptoms of pellagra are dermatitis, dementia, and diarrhea. This is because niacin deficiency is most noticeable in the body parts with high rates of cell turnover, such as the skin or gastrointestinal tract (Goldberger et al., 1923).
The growing interest in the environmental stress has been accompanied by a rapid accumulation of evidence indicating that the environment can elicit substantial stress in people living in urban environments. Furthermore, it is widely conceived that the natural environment can enhance human health. There have been several questionnaire studies and investigations on the psychological effects of forest environments. A previous study found an enhancement of the positive emotions among subjects who were shown pictures of natural environments. Moreover, other researches have also found that forest environments improve the psychological wellbeing of people
As the techniques that have enabled us to analyses and assess a biopsy become ever more sophisticated, we have realised the limitations of looking at the single snap-shot of the tumour. This single-biopsy bias was highlighted in which it was mainly demonstrated that a portion taken from different parts of a primary tumour and its metastases showed and proved extensive intertumoural and intratumoural evolution. This tumoural heterogeneity mainly highlights the difficulty of dictating a therapeutic course of action based on the single biopsy, as it is likely to underestimate the ramification of the genomic landscape of the tumour (Chomczynski et al., 2016).Having established that there is mainly considerable tumour heterogeneity, taking multiple biopsies from the patients‘ primary tumour and the metastases would seem to be the most obvious next step. There are so much difficulties in obtaining the tissue biopsy— including the discomfort suffered by the patient, the inherent clinical risks to the patient
Rivivna humilis berry extract as fungal sourceDr. sreeremya S
The introduction of the mankind had marked the continuous exploitation of the plants as organisms and their products for the pharmacological prospects and key features (Guha et al., 1999). In most of the agronomic domains around the globe, the conventional modes of the treatment are still in exercise and also in upcoming research (Srivastava et al., 2003).
These approaches most commonly exploit the various dynamics and much specific potential and applications of plant extracts (Bonde et al., 2007) . The distinctions of the first and foremost large-scale screening of the green plants evaluate and also assess the antimicrobial activity of 2,300 plants (Nautiyal et al., 1984).
Dyeing is an ancient and traditional art which predates written records. It was practised specifically during the Bronze Age in Europe (Sreeremya, 2016). Conventional dyeing techniques encompassed sticking plants to fabric or rubbing crushed pigments into cloth.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.

Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.

Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
