The Position of Viruses in the Biological Spectrum
Viruses infect every type of cell, including bacteria, algae, fungi, protozoa, plants, and animals
Seawater can contain 10 million viruses per milliliter
For many years, the cause of viral infections was unknown:
Louis Pasteur hypothesized that rabies was caused by a “living thing” smaller than bacteria
He also proposed the term virus, which is Latin for “poison”

Discovery of Viruses
Ivanovski and Beijerinck showed that a disease in tobacco was caused by a virus.
Loeffler and Frosch discovered an animal virus that causes foot-and-mouth disease in cattle.
Filterable virus:
These early researchers found that when fluids from host organisms passed through porcelain filters designed to trap bacteria, the filtrate remained infectious.
This proved that an infection could be caused by a fluid containing agents smaller than bacteria.

The Viral Debate
Two sides of the debate:
Since viruses are unable to multiply independently from the host cell, they are not living things and should be called infectious molecules
Even though viruses do not exhibit most of the life processes of cells, they can direct them, and thus are certainly more than inert and lifeless molecules
Viruses are better described as active or inactive rather than alive or dead

“OUTBREAK OF CORONA VIRUS: A DETAILED REVIEW
: The COVID-19 pandemic is spreading across the globe at an alarming rate. Corona Virus is a large
family of positive-sense, single-stranded Ribo Nuclic Acid(RNA) viruses that belong to the Nidovirales order. It
was first started in Wuhan, Hubei Province, China and then subsequently spread to dozens of other countries
becoming a global pandemic. COVID-19 manifests with a wide clinical spectrum ranging from asymptomatic
patients to septic shock and multi organ dysfunction. The most common symptoms of patients include fever (98.
6%), fatigue (69.6%), dry cough, and diarrhea. The WHO recommends collecting samples from both the upper
and lower respiratory tracts. This can be achieved through expectorated sputum, broncho-alveolar lavage or
endotrachial aspirate, These samples are then assessed for viral RNA using polymerase chain reaction(PCR).
Patients with pre-existing co-morbidities have a higher case fatality rate. These co-morbidities include diabetes (7.
3%), respiratory disease(6.5%), cardiovascular disease(10.5%), hypertension(6%) and malignncy(5.6%). Patients
without co-morbidities have a lower case fatality rate(0.9%). Preventive measures must focus on optimizing
infection control protocols, self-isolation, and patient isolation during the provision of clinical care. No confirmed
medication or vaccine has been developed. Current treatment strategies are aimed at symptomatic care and
oxygen therapy. Chloroquine phosphate and lopinavir/ritonavir have been suggested. Other suggested anti-virals
include ribavirin and abidor. Usage of personal protective equipment, washing hands, sanitization, social distance
and general awareness can stop transmission of virus. Prophylactic vaccination is required for the future
prevention of COV-related epidemic or pandemic.

Solution
As per the rule i have answered your first question:
Reoviridae: Reoviridae are currently classified into nine genera. The genomes of these viruses
consist of 10 to 12 segments of dsRNA, each generally encoding one protein. The mature virions
are non-enveloped. Their capsids, formed by multiple proteins, have icosahedral symmetry and
are arranged generally in concentric layers. A distinguishing feature of the dsRNA viruses,
irrespective of their family association, is their ability to carry out transcription of the dsRNA
segments, under appropriate conditions, within the capsid. In all these viruses, the enzymes
required for endogenous transcription are thus part of the virion structure.
Orthoreoviruses: The orthoreoviruses (reoviruses) are the prototypic members of the virus
Reoviridae family and representative of the turreted members, which comprise about half the
genera. Like other members of the family, the reoviruses are non-enveloped and characterized by
concentric capsid shells that encapsidate a segmented dsRNA genome. In particular, reovirus has
eight structural proteins and ten segments of dsRNA. A series of uncoating steps and

Case study: A number of people, including children, became ill several days after eating the
same brand of a salami-type sausage. Rather than being cooked, the sausage was made by a
fermentation process. Symptoms included diarrhoea (often bloody), severe stomach cramps,
nausea and headache. Some of the children became irritable and listless, and were taken to
hospital. They were found to be suffering from haemolytic uremic syndrome (HUS). In spite of
kidney dialysis and other treatment, one of the children died a week later from a blood clot on
the brain. Some of the other children with HUS had only 50% normal kidney capacity and there
was a risk of long-term damage. Routine testing of samples from the children did not show up
any pathogens. However, specialized tests showed up a toxin similar to Shigella toxin.

CASE STUDY
The graduate admissions process at begins with an applicant creating an application on the
application website. If the applicant does not have a student ID, they must create a new account,
otherwise they can log in with their student ID. Applicants select the program they wish to apply
for, and their desired entry semester. Next, applicants need to provide personal information, and
answer three questions about why they wish to study the chosen program, what they hope to
achieve after completing the program and any special circumstances to be considered. Applicants
must provide the names and email addresses of two referees. Applicants can upload multiple
documents, such as their CV, confirmation of their undergraduate degree, English language
proficiency certificates, etc. When applicants submit an application, they must pay the
application fee by credit card. After payment and submission, the application system will
automatically send emails to the two referees with a link to a web page where the referees can
provide references about the applicant. When these references are entered, they are added to the
application. After an applicant submits an application, they are able to upload further documents
until the application is finally decided on by the School of Graduate Studies (SGS) enrolment
director later in the process (see below). After an application is submitted, the application system
creates and assigns a student ID to new applicants. the School of Graduate Studies (SGS) staff
performs an initial check to decide which academic department the application should be sent to,
and passes it to the graduate admission staff of that department. When the graduate admissions
staff of the academic department receives an application from SGS staff, they check for entry
semester and completeness of the application. If an applicant has selected an entry semester for
which no admission is offered, the graduate admission staff complete a form to recommend
rejection of the applicant with an offer of reconsideration to the next available semester. This
recommendation form is passed to the graduate officer (GO) of the academic department. If
admission is offered for the desired entry semester but the application is incomplete, nothing is
done while the graduate admission staff waits for further documents or references. The graduate
admission staff must regularly check the application for completeness, because neither the
application system nor SGS notifies the academic department when additional documents arrive
(either submitted by the applicant, or references entered by referees). If an application is still
incomplete by the application deadline, the graduate admission staff fills in a form to recommend
rejection of the applicant and send this recommendation to the graduate officer (GO) of the
academic department. The GO can either accept or reject the recommendation by the graduate
admission staff to reject an applicant. If the recommendat.
Case study Read the following case study and write your report about t.pdf
Case study Read the following case study and write your report about the project formotion
damage concepts in the field and state your final conclusion. Abstract The Ruba reservoir in the
Casanare region of Colombia is currently being appraised and developed. Cost effective
development of the reservoir will be dependent on applying optimum drilling and completion
practices. The purpose of this poster session is to provide a case study history for the approach
and evolution of the project as it pertains to attainine an improved understanding of fonnation
damage mechanisms. Introduction Background Ruba Field is located in the kithills, 150 miles
northeast of Africa. Light (>34* AP1) oil, gas and condensate in Ruba occur at drilling depths
which average 16000 ft . in an asymmetric hanging wall anticlinal trap 14 miles long and 3 miles
wide, formed during the Mioceneto-fiecent deformation. Top and lateral seals are provided by
marine mudstones of the Oligocene Carbonera Group, and support a hydrocarbon column of over
1600 ft . The region is tectonically stressed in the formations which overlay the Ruba reservoir.
Because of this, drilling conditions are ditficult with wellbore instability, mud losses, and stuck
pipe common. Geology and Mineralogy Over 50% of the reserves occur in Late Eocene Mirador
Fm sandstones, deposited in fluvial and shallow marine environments. Additional, deeper
reservoirs include fluvial and shallow marine Paleocene Barco Fm sandstones, and the shallow
marine Campanian Upper Guadalupe Sandstone Fm. Porosity in fuba is relatively low, and
averages 9% in the Mirador Fm . Good permeability is retained, however, because the reservoirs
are pure quartz-cemented quartz arenites, in which permeability-reducing authigenic clays and
carbonate cements are absent. Core and well test analysis indicate matrix permeability, not
fracture permeability, provides the high deliverability (> 12,000 BOPD) of Ruba wells.
Reservoir Fluids Ruba hydrocarbon phases exist in a near miscible, critical point state. Analysis
indicates very high liquids recoveries will be achieved using reinjection of produced gas. The
field will therefore be developed using reinjection of produced gas to maintain reservoir pressure
and vaporize residual liquids. The field contains significant volumes of hydrocarbon liquids and
large volumes of gas. Key Components of the Well Process Analyzed The study focuses on
evaluating the key phases within the well process that are known to influence mechanical skin
damage and corresponding well productivity. The phases analyzed include conceptual planning,
reservoir mud systems, wellbore constraints, mud losses, hardware constraints, perforating
parameters, kill pill designs, and completion brines. Drill Stem Testing Operations 16 drill stem
tests have been conducted for Ruba over the previous 2 years that are considered valid for
analyses and calculation of mechanical damage skin. The majority ( 7 out of 8 DSTs) of the data

CASE FILE Gas Gangrene A 77-year-old male resident of southern Colorad.pdf
CASE FILE Gas Gangrene A 77-year-old male resident of southern Colorado was brought to the
emergency room somewhat disoriented and with swelling and severe pain in his leg. The trlage
nurse observed that the patient's skin was discolored and blistering and had an unpleasant odor.
The patlent's history revealed that he had diabetes, which was poorly controlled with metformin
and had Injured his leg in a fall 2 months previously. An X ray revealed pockets of gas between
tissue layers in the lower leg. Blood and tissue samples were sent for culture. The patient was
moved to the ICU and treatment was immediately begun with plperacillin, moxifloxacin, and
vancomycin. The patient's family was counseled that depending on the results of the culture and
the progression of his disease, he might need amputation or treatment in a hyperbaric chamber.

Case History- Tracking a -Patchwork Quilt- Pathogen Nine-month-old Eva.pdf
Case History: Tracking a "Patchwork Quilt" Pathogen Nine-month-old Eva had 12 clinic visits
over a 7-month period because of a runny nose and/or ear infections. During each episode,
nasopharyngeal swabs were obtained for bacterial culture, and Streptococcus pneumoniae was
revealed. Although all the infections were resolved with antibiotics, scientists gained insight into
pathogen evolution by seeing how the isolates compared. Each isolate was first analyzed for
seven genes that can indicate strain variability-a process called multilocus sequence typing
(MLST). The lab found two MLST types, indicating that the patient was infected with two
different strains of S.pneumoniae. However, when the complete genomes of several of the
isolates were sequenced and compared, four different genotypic strains were identified-all of
which evolved as a result of 16 distinct recombination events between strains (Figure 9.21).
Curiously, the technicians noticed that some recombined sequences did not seem to come from
either of the two primary coinfecting strains. Instead, it appeared that this new DNA came from
uncultured and undetected strains of S . pneumoniae that had colonized Eva's throat at one time
or another. Horizontal gene transfers (transformations) between the undetected and detected
isolates appear to have produced, like a patchwork quilt, the new recombined strains of S .
pneumoniae. The genome sequence data clearly support the idea that S . pneumoniae evolution is
characterized by high rates of horizontal gene transfer and recombination. 2nd attempt Which of
the following statements best describes how multiple S. pneumoniae genotypes arose during
Eva's multiple infections? Choose one: A. S. pneumoniae acquired DNA from Eva's throat cells
that had lysed due to recurrent colonization. B. Competent S. pneumoniae took up DNA from
other S. pneumoniae cells that had died. C. It occurred by pilus-mediated contact and transfer of
genes between two individual living S . pneumoniae cells. D. Chromosomal genes were
transferred among S. pneumoniae by bacteriophage..

Operation Blue Star - Saka Neela Tara
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Embracing GenAI - A Strategic Imperative
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
