The document discusses COVID-19 (coronavirus), including what it is, where it originated from, how it affects the body, comparisons to the flu, whether it will be a slow or fast pandemic, current statistics, and how to flatten the curve. It explains that COVID-19 spreads via droplets from infected individuals and primarily targets the lungs, intestines, and spleen. While the immune system initially fights the virus, it can become overwhelmed, leading to potential death. Social distancing measures like hand washing, quarantines, and limiting gatherings are encouraged to slow the virus's spread and avoid overwhelming healthcare systems.

This document discusses COVID-19 (coronavirus). It describes the virus, how it originated in China in December 2019, and how it spreads and affects the body. Key symptoms of COVID-19 are listed and compared to influenza. Statistics on global cases and deaths are provided as of March 31, 2020. The importance of "flattening the curve" through social distancing, quarantines, hand washing, and other measures is explained to help slow the spread and prevent healthcare systems from being overwhelmed.
1) The document discusses seasonal flu vaccines that were available in October 2009 in Dallas and surrounding areas, as news reports indicated shortages. 2) Seasonal flu kills approximately 36,000 people and sends over 200,000 to the hospital each year in the US. 3) The most common flu symptoms are fever, sore throat, coughing, and body aches.
The document discusses infections that affect immunocompromised patients. It describes two main categories of immunodeficiency: defects in innate immunity and deficiencies in adaptive immunity. A wide range of opportunistic pathogens can cause infections in immunocompromised patients, including bacteria like Pseudomonas, fungi like Candida and Cryptococcus, viruses like EBV and adenovirus, and protozoa like Cryptosporidium. Certain infections are more common depending on the underlying cause of immunosuppression, such as Aspergillus infections in neutropenic patients or Pneumocystis pneumonia in AIDS patients.
This document discusses COVID-19 and the possibility of developing a vaccine. It defines COVID-19 as a disease caused by the SARS-CoV-2 coronavirus. It describes the structure and transmission of SARS-CoV-2, how COVID-19 cases are defined, symptoms, and current treatment options. The document also provides an overview of different types of vaccines and their mechanisms of action. It notes that while an effective vaccine is possible given immune responses to the virus, development faces challenges due to the coronavirus's ability to mutate rapidly.

There is no vaccine and treatment is supportive.
The document discusses several deadly diseases throughout history including:
- Polio, which spread through contaminated food/water and peaked in the US in 1952 before a vaccine was developed.
- Typhus, which spread in crowded cities from 1600-1800s and killed over 10 million during the Thirty Years War.
- AIDS, which has killed over 25 million since the 1980s and has no cure.
- Malaria, which has infected humans for nearly 4,000 years and still impacts sub-Saharan Africa.
- Cholera, which spreads through water/food and still causes outbreaks with 120,000 deaths annually.
The document summarizes information about coronaviruses, including the novel coronavirus that caused an outbreak in Wuhan, China in late 2019. It describes coronaviruses as enveloped, positive-sense RNA viruses that primarily infect the respiratory and gastrointestinal tract of mammals and birds. Six strains are known to infect humans, including SARS-CoV-2, the virus that causes COVID-19. As of early 2020, the outbreak has infected over 6000 people in China and spread to 18 other countries, with the majority of cases and deaths occurring in China. Treatment focuses on relieving symptoms, and precautions include handwashing and avoiding contact with infected individuals.
Coronaviruses are a large family of viruses that are known to cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS).
A novel coronavirus (COVID-19) was identified in 2019 in Wuhan, China. This is a new coronavirus that has not been previously identified in humans. im mentioned in this ppt about Coronavirus disease symptoms, transmission, mechanism, treatment, diagnosis etc.
Coronavirus disease (COVID-19) is caused by a newly discovered coronavirus called SARS-CoV-2. Common symptoms include fever, tiredness, and dry cough, with most patients recovering without special treatment. However, older individuals and those with pre-existing medical conditions are more vulnerable to severe illness. While bats were believed to be the original host, the exact origin of SARS-CoV-2 is still unclear. The initial epicenter was Wuhan, China, though person-to-person spread has led to a global situation with rising case numbers and death tolls that vary by age. Preventive measures center around social distancing, quarantines, and maintaining good hygiene.
This document provides information about COVID-19, including what it is, why it's called COVID-19, its symptoms, how it is transmitted, differences from a cold or flu, prevention and treatment. It begins by explaining that COVID-19 is a new coronavirus that emerged in Wuhan, China in late 2019 and is part of a large family of viruses that can cause illness in humans and animals. The document then discusses COVID-19's symptoms, how it is transmitted through coughs or touching contaminated surfaces, that current treatment involves self-isolation and medical care if symptoms are severe, and that prevention focuses on good hygiene.
Corona viruses are a group of related RNA viruses that cause diseases in mammals and birds.
In humans, these viruses cause respiratory tract infections that can range from mild to lethal.
Mild illnesses include some cases of the common cold (which is also caused by other viruses, predominantly rhinoviruses), while more lethal varieties can cause SARS, MERS, and COVID-19.
What is named COVID – 19 ?
The document discusses viral diseases and their treatment. It defines a viral infection as an illness caused by a virus entering the body. Symptoms of viral infections can affect any body system and include fever, chills, and flu-like symptoms. There are many types of viral diseases, including HIV/AIDS, herpes, influenza, measles, and Ebola. The diagnosis and treatment of viral diseases varies depending on the specific virus. Treatment may include symptomatic relief, supportive care, antiviral drugs that target different parts of the viral lifecycle, and hospitalization for severe cases.
The document discusses the Corona virus, its origins, symptoms, and differences between viral and bacterial infections. It originates from the coronavirus family and causes respiratory illness. Common symptoms include coughing, fever and inflammation. While bacteria can be treated with antibiotics, viruses cannot as they have the same cellular mechanism as human cells. The document also examines how the virus has spread globally and prevention methods different countries have implemented like travel restrictions, school/business closures and increased sanitation.

This document discusses SARS-CoV-2 and COVID-19. It defines coronaviruses and describes past outbreaks of SARS and MERS. It explains that SARS-CoV-2 was identified in Wuhan, China in December 2019 and has since caused a global pandemic. The document outlines SARS-CoV-2's structure, transmission, symptoms, diagnosis and treatment. It provides recommendations for prevention including hand washing, social distancing and correct mask usage.
Viral diseases are caused by viruses and include many common illnesses like the common cold, chickenpox, dengue fever, rabies, and encephalitis. Chickenpox is caused by the varicella zoster virus and causes an itchy rash. Dengue fever causes fever, headache, joint pains and a skin rash similar to measles. Rabies virus is transmitted through animal bites and causes neurological symptoms. Encephalitis is an inflammation of the brain that can be caused by viruses like herpes, polio, and measles infecting the brain.

The document summarizes information about COVID-19. It began in Wuhan, China in December 2019, when several cases of an unknown pneumonia were reported. Officials later identified it as a new coronavirus called SARS-CoV-2. It spreads mainly through respiratory droplets when an infected person coughs or sneezes. Common symptoms include fever, cough, and shortness of breath. While 80% of cases are mild, it can cause severe pneumonia and death in some cases, especially among the elderly and those with pre-existing conditions. China has faced over 82,000 cases but has recovered most patients, while the virus has since spread globally.
Coronavirus disease (COVID-19) is caused by a newly discovered coronavirus called SARS-CoV-2. It was first reported in Wuhan City, China in December 2019.

The Effects of Pandemic- Corona Virus on Whole World.pptxDanyDany88
Corona viruses can cause respiratory illnesses in humans and animals. COVID-19 is caused by the SARS-CoV-2 virus, which is believed to have originated in bats. It has caused a global pandemic with over 4.8 million deaths as of October 2021. Symptoms range from mild to severe and can include fever, cough, loss of taste/smell, and difficulty breathing. Prevention methods include vaccination, masks, distancing, handwashing, and isolation when sick. The pandemic has had widespread economic and social impacts, including increased poverty and food insecurity as well as short term improvements to air quality and reductions in pollution.
- The document discusses the Covid-19 pandemic, providing an overview of the virus and its spread worldwide. It notes that Covid-19 has infected over 3.7 million people globally, causing over 259,000 deaths.
- Symptoms of Covid-19 range from mild to severe and can include fever, cough, shortness of breath. Around 14% of cases progress to pneumonia and 5% are critical. The elderly and those with preexisting conditions are at higher risk.
- Covid-19 is diagnosed through PCR tests of nasal and throat swabs. Antibody tests can also detect if a person has been infected. The case fatality rate of Covid-19 is around 2.
The document discusses COVID-19, its origins, evolution, symptoms, transmission, prevention and mortality. It notes that COVID-19 originated in Wuhan, China in late 2019. It is caused by a coronavirus that is transmitted through respiratory droplets. Common symptoms include cough, fever and shortness of breath. Basic prevention measures include hand washing, social distancing and wearing face masks. Mortality rates vary by country and are highest among older individuals and those with underlying conditions. Vitamin D deficiency may also increase risk of severe outcomes.
Advanced age, having comorbidities, and vitamin D deficiency are three most important reasons for increased vulnerability to COVID-19 and also worsen complications and increase the risk of death.
Despite the vast amount of information available and lessons learned, many countries are still not fully utilizing these to manage secondary peaks of COVID-19 infection. Factors associated with worse COVID-19 prognosis include, older age, ethnicity, male sex, having comorbidities, obesity, diabetes, hypertension, and smoking; all these are associate with vitamin D deficiency. COVID-19 symptomatology varies from
mostly asymptomatic, to, up to 2% fatality. The latter is characterized by cytokine storm, an immune reaction, diffuse arterial thromboembolism, acute respiratory distress syndrome, pulmonary oedema,and death.

Abstract:
In the month of December, 2019 there was outbreak of pneumonia with unknown reason in Wuhan, China. Wuhan is the center of attention because of the respiratory disorder cause by a virus called Corona and also known as Novel COVID – 19. Validate the existence of this virus was also diagnosed in Wuhan. Then it start spreading all over the world due to the social gatherings. It ultimately take thousands of people towards death. Then after its huge destruction a final step of lockdown is taken up by the government of each country. The animal-to-human transmission was presumed as the main mechanism. It was concluded that the virus could also be transmitted from human-to-human, and symptomatic people are the most frequent source of COVID-19 spread. The virus-host interaction and the evolution of the epidemic, with specific reference to the times when the epidemic will reach its peak.
Introduction:
There is scanty knowledge on the actual pandemic potential of this new SARS-like virus. It might be speculated that SARS-CoV-2 epidemic is grossly underdiagnosed and that the infection is silently spreading across the globe. There are no comparable analogies to corona virus. This virus is not like any of the other epidemiological threats that have emerged in recent decades; it is less fatal but much more contagious.
Distribution of cases by the following:
· Time: The outbreak of 2019 novel coronavirus disease (COVID-19) was first reported on December 31, 2019.
· Place: the epidemiology of 2019 novel coronavirus disease (COVID-19) in a remote region of China, far from Wuhan, we analyzed the epidemiology of COVID-19 in Gansu Province
Explanation of the research topic (corona virus):
As the outbreak of coronavirus disease 2019 (COVID-19) is rapidly expanding in China and beyond, with the potential to become a world-wide pandemic, real-time analyses of epidemiological data are needed to increase situational awareness and inform interventions. The current most likely hypothesis is that an intermediary host animal has played a role in the transmission. Identifying the animal source of the 2019-nCoV would help to ensure that there will be no further future similar outbreaks with the same virus and will also help understanding the initial spread of the disease.
Numerator (cases of corona virus):
Deaths divided the total of deaths plus recoveries. In early days because of the exponential increase new cases significantly outpace recoveries. You’re dividing by new cases but the numerator hasn’t had a chance to catch up to the death toll yet to be associated with those cases. If you look at COVID 19 on Feb 17, you get the 2% number only if dividing by total cases. If you look vs recovered cases, it’s 13%.
The WHO’s fatality percentage, announced March 17, 2020, is based simply on the number of deaths g.

A Perspective Approach of Community Medicine in Corona Virus Disease COVID 19ijtsrd
Coronavirus disease COVID 19 is an infectious disease caused by the SARS CoV 2 coronavirus, which has spread rapidly across the world. The World Health Organization WHO proclaimed the COVID 19 outbreak a pandemic in March 2020. The pandemic has wreaked havoc on global health systems, as well as economic and social development. The rate of transmission is relatively high.As a result, regardless of vaccine history or previous infection, the CDC recommends that anyone with any signs or symptoms of COVID 19 be checked. Everyday Preventive Actions, as well as having the Covid 19 Vaccine when it is safe, will protect you and your loved ones.

This document discusses different types of polymers including natural, synthetic, and semi-synthetic polymers. It describes methods of polymerization such as step-growth, chain-growth, ring-opening, and coordination polymerization. Specific polymers are also mentioned including polyesters, polycarbonates, polyamides, polyurethane, nylon 6, polyethylene oxide, and polypropylene oxide. The document provides an overview of polymer chemistry concepts like molecular weight calculation, crystalline structures, glass transition and melt temperatures, and different polymerization reactions.
This document discusses the failures in addressing past epidemics like SARS and MERS that contributed to the spread of COVID-19. It argues that governments and industries prioritized other areas like cancer research and extending lifespan over researching epidemic diseases. This left few experienced researchers behind to confront new diseases rapidly. It also criticizes overpopulation, urbanization, and a reliance on experienced employees rather than training new graduates. The document warns that if we do not learn from past mistakes and find cures for animal-borne diseases, future pandemics may be even more severe.
This document discusses vitamin D, including what it is, how the body processes and activates it, its functions, sources, and requirements. Vitamin D is a fat-soluble vitamin synthesized in the skin upon exposure to sunlight and found in some foods. It is activated through two hydroxylation steps in the liver and kidneys. Vitamin D promotes calcium absorption and bone mineralization and supports immune function. While sunlight is the major source, many factors impact skin synthesis, so dietary sources and supplements are also important to meet daily requirements.
Naming compounds and Balancing chemical equations using oxidation numbersRania S Seoudi
1) The document discusses naming compounds and balancing chemical equations using oxidation numbers. It provides examples of naming metal and non-metal compounds as well as oxide compounds.
2) Methods for determining oxidation numbers from compound names and formulas are explained. Examples are given for nitrate compounds and working out formulas from compound names.
3) The document demonstrates balancing chemical equations using oxidation numbers, giving examples of copper (II) oxide reacting with ammonia and manganate (VII) ions reacting with iron (II) ions.
1) Calorimetry can be used to measure the enthalpy change of reactions by using either a constant pressure calorimeter or a bomb calorimeter.
2) The enthalpy change is calculated using the formula: ΔH=-mcΔT, where m is the mass of the calorimeter contents, c is the specific heat capacity, and ΔT is the temperature change.
3) For example, a student measured a 6.5°C temperature increase when mixing 50mL of 1M HCl and 50mL of 1M NaOH. Using the calorimetry equation, the enthalpy change for the neutralization reaction of 1 mole of HCl with NaOH
This document summarizes different types of enthalpy changes in chemical reactions. It defines exothermic reactions as releasing energy to the surroundings and endothermic reactions as absorbing energy from the surroundings. Enthalpy change is the energy exchange between a reaction and its surroundings at constant pressure. The document explains how to calculate enthalpy change and represents reaction pathways using enthalpy profile diagrams to show enthalpy changes for exothermic and endothermic reactions. It also defines standard enthalpy changes of combustion, neutralization, solution, and hydration of salts.

The debris of the ‘last major merger’ is dynamically youngSérgio Sacani
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.
Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...AbdullaAlAsif1
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
Nucleophilic Addition of carbonyl compounds.pptxSSR02
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.
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.
BREEDING METHODS FOR DISEASE RESISTANCE.pptxRASHMI M G
Plant breeding for disease resistance is a strategy to reduce crop losses caused by disease. Plants have an innate immune system that allows them to recognize pathogens and provide resistance. However, breeding for long-lasting resistance often involves combining multiple resistance genes

Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.
