Sodium bicarbonate (Na+HCO3- ) is mildly alkaline and it reacts withacids: H+ + HCO3- =H2CO3 (carbonic acid) which is unstable inwater and breaks down into water & Carbon Dioxide : H2CO3(aq) --> H2O(l) + CO2 (g) . Inan open container at atmospheric pressure, the CO2 escapes, so thereaction is irreversible. Alka Seltzer must contain some mildacid in solid form, maybe acetylsalicylic acid (aspirin). When placed in water, the acid and bicarbonate react and fizz(CO2). Bicarbonate is useful in antacids for the same reason- stomach acid (HCl) reacts with the bicarbonate producing waterand carbon dioxide. The carbon dioxide leaves (burp!) andonly water remains where there once was a strong acid.

The water must be boiled to remove traces of dissolved carbon dioxid.pdf
The water must be boiled to remove traces of dissolved carbon dioxide (CO2).
CO2 dissolves in water to form carbonic acid (H2CO3):
CO2 + H2O => H2CO3
H2CO3 is a weak acid and partially ionizes to give H+ ions:
H2CO3 => H+ + HCO3-
HCO3- => H+ + CO32-
The H+ ions can decompose thiosulfate ions and reduce the concentration of sodium thiosulfate
according to the reaction:
2 S2O32- + H+ => HSO3- + S

Ergonomics
Definition : Ergonomics defines from two Greek words ergon means work and nomoi means a
natural laws, to create a word that means the science of work and a person’s relationship to that
work. It is a term thrown around by health professionals and marketing mavens with a cavalier
attitude. For some it has a very specific meaning.
The scientific discipline concerned with the understanding of interactions among humans and
other elements of a system, and the profession that applies theory, principles, data and methods
to design in order to optimize human well-being and overall system performance.It is the attempt
to make work better that ergonomics becomes so useful. And that is also where making things
comfortable and efficient comes into play.
Ergonomics is commonly thought of in terms of products. But it can be equally useful in the
design of services or processes.
Implementation
Developing and Implementing an Ergonomics Process and is written from the stand point of the
early stages of initiating a process. The procedure begins with someone identifying the need and
approaching management for support than the champion. Typically, the champion should gather
data to provide management with justification for the project. Some of these topics were
addressed in Section but are reiterated here to provide an overview of the entire strategy or plan
of implementing a process. Once management has agreed to support the project, a sponsor is
selected from upper management. The corporate office sponsor is responsible for writing a
project charter that recognizes the business need for implementing an ergonomics process . The
charter will provide written documentation of management’s commitment to the project, stating
that safety and health is as important as production. Management should identify the appropriate
cost account for the project and give an estimated budget for implementation. Management
should also choose or recruit the project manager early in these stages so he or she may
participate in the planning process. The champion may be assigned the position of project
manager or another candidate may be recruited to fill the position. Depending on the
organizational structure there may also be facility project managers. The charter should also
provide for the formation of a multi-functional ergonomics team. Depending on the size of the
company, there may be a committee at each facility. Management should provide documented
authority to the manager and should authorize time and money expenditures for the committee. It
is the responsibility of the project manager to assign and communicate responsibilities to the
project . The ergonomics initiative is typically part of the health and safety department or the
engineering department. In addition to the creation of the committee, management should outline
its position on ergonomics in other areas.
For example, ergonomics should be a consideration for all new product designs, tools, new

A gastric or stomach ulcer is regularly caused by an infection with .pdf
A gastric or stomach ulcer is regularly caused by an infection with bacterium Helicobacter pylori
(H. pylori) and long-term use of non-steroidal anti-inflammatory drugs (NSAIDs), such as
ibuprofen and aspirin.
1. To detect an ulcer, first take a consideration of pre-medical history and execute a physical
exam.
2. Laboratory tests for H. pylori :
Blood tests are normally inaccurate and should not be regularly used and the breath test is the
most accurate.
For the breath test, eat or drink something containing radioactive carbon. H. pylori break down
the material in the stomach. Later, blow into a bag, which is then sealed. If infected with H.
pylori, your breath sample will contain the radioactive carbon in the form of carbon dioxide.
Endoscopy was used to examine the upper digestive system. During endoscopy, passes a hollow
tube equipped with a lens of endoscope down to throat and into esophagus, stomach and small
intestine. This endoscope had revealed the ulcers in the stomach.
If detects an ulcer, small tissue samples may be removed for examination in a lab for biopsy test.
A biopsy also identify whether H. pylori is in the stomach lining.

dfifferent files, graphics, html from one place to another place through internet, so it is not
possible to send those information at a time. It will be divided in to some packets according to
their size which is taken along them will be transferred through packets to the routers and we can
take those informations to our gadjets or anything. It will change to different packets when they
pass through the different layers of network packets.
The packets are delivered from one place to another place by using differnt
protocols like Transfer control protocol and user datagram protocol. These two are responsible
for packet delivery through internet and this is how the information is passed from one work
station to another by using packets. without these it is very difficult to transfer.

1.salbutamol sulfate (Ventolin)- the molecular formula of salbutamo.pdf
1.salbutamol sulfate (Ventolin):- the molecular formula of salbutamol sulfate (Ventolin) is
(C13H21NO3)2 • H2SO4
o Mechanism of action:- It stimulates 2 adrenergic receptors. It has a bronchodilator effect. It
causes the activation of enzyme adenyl cyclase, adenyl cyclase enzyme form cyclic AMP
(adenosine-mono-phosphate) from ATP (adenosine-tri-phosphate). Bronchial smooth relaxes in
the prsence of high level of cyclic AMP by which airway resistance decreases by lowering
intracellular ionic calcium concentrations. Release of bronchoconstrictor mediators such as
histamine, leukotreine from the mast cells in the airway inhibited by the high level of cyclic
AMP.
o side effects/adverse effects :-Its side effects/adverse effects depends on its dosage and route of
administration. The most common side effects of salbutamol is found a fine tremor of skeletal
muscle of hands and nervousness. Palpitation, tachycardia, chest discomfort, headache, muscle
cramps, hypokalemia, difficulty in micturition and paradoxical bronchospasm also caused by
salbutamol.
o potential medication interactions:- It can be given as tablet, syrup, inhaler, nebulizer solution
and intramuscular or intravenous injectable form. The medication of oral salbutamol is 2 to 4 mg
three times a day in adult and 1 to 2 mg three times a day in children. As per the requirement the
One to two puffs (100 to 200 microgram) of salbutamol metered dose inhaler is inhaled. As
nebulizer solution 1 to 2 ml of salbutamol nebulizer solution should be diluted with normal
saline to final volume of 2-4 ml is inhaled from a nebulizer. In severe acute attack, 5 to 10 ml
(each ml contain 50 microgram) of salbutamol injection can be given by intramuscularly or
intravenously.
2.Advair Diskus:- It is a combination of a corticosteroid and a beta2-adrenergic bronchodilator.
Mechanism of action:- It contains both fluticasone propionate and salmeterol. They both have
seprate mechanism of action given below:-
For Fluticasone Propionate:- It has anti-inflammatory activity and it is a synthetic trifluorinated
corticosteroid .In vitro it exhibit a binding affinity for the human glucocorticoid receptor.
Asthma caused by inflammation, Corticosteroids acts on actions on multiple cell types like, mast
cells, etc.
For Salmeterol Xinafoate:- It is is a selective LABA.In vitro, it is 50 times more selective for
beta2-adrenoceptors than albuterol. They are predominant adrenergic receptors found in
bronchial smooth muscle. And in heart beta1-adrenoceptors are predominant, it is comprising
10% to 50% of the total beta-adrenoceptors. The beta2-adrenoceptor agonist drugs contains
salmeterol, stimulates the intracellular adenyl cyclase, adenyl cyclase enzyme form cyclic AMP
(adenosine-mono-phosphate) from ATP (adenosine-tri-phosphate). Higher level of c-AMP
causes relaxation of bronchial smooth muscle and release of mediators is inhibited by immediate
hypersensitivity from cells, especially from mast cells. salmeterol is a potent.

1) The first abstract suggest that predator / prey relationship outcome of P.fiesteria and
rhodomonas is determined by presence and absence of specific bacterium that is a alpha-
proteobacterium which have sequence similarity with roseobactor species present in toxic
dianoflagellete species. In the presence of this bacterial isolate consumption of rhodomonas is
increase that ultimately leads to the growth of Pfiesteria. Molecular analysis of ameboied stages
of toxic culture of clonal P. fiesteria species by verious research group suggested that P. fiesteria
species differe in response to fresh fish mucus, algal prey and inorganic nutrient enrichment
depending on funtional type or toxicity status. There are three functional type of P. fiesteria
ToxA, ToxB, NonIND depending upon their toxicity in the presence of fish, zoospore production
and attraction to fish excreta and mucus. So, this study suggest that Non IND strain should not
used for research about environment control on toxic strain of P fiesteria species.
Right environment condition (overencrichment of nutrient (N&P) - P. fiesteria exposed to large
number of finfish- increase toxin production- distroy fish epidermis- once fish dead- reduce its
toxin production- feeds on the fish either as zoospores or other forms
Whenenvironment condition change- finfish few or low in number - P.fiesteria become nontoxic
or dormant
P. fiesteria also effect people learning and reading capacity and couse other symptoms who are
very close to the contaminated water such as fishermen.
P. fiesteria growth is controlled by temperature and water quality.
3) Production of toxin, toxic activity and attraction to fresh fish tissue and excreta are the
responsed that activated by signal in variably toxic strains of P.fiesteria.
4) inorganic nutrient enrichment, presence of fresh fish and algal prey cause the development of
three strains
5) development of toxicity in Pfiesteria is caused by presence of fresh fish tissue and excreta and
its couse death of live fish. ToxA cause maximum killing have strong attraction to live fish
whereas Tox B has intermediate effect, and Non IND has negligible effect becouse have low
attraction to fresh fish and maximum zoospore production capacity.
2) THE symbiotic relationship of bacteria with Pfiesteria control its growth and consumption of
rhodomonas so to increase consumption of itself P.fiesteria adopt a colonization with bacteria.

Multiplicity refers to the number of signals in t.pdf
Multiplicity refers to the number of signals in the NMR spectrum that correspond to
a single proton. A proton can be \"split\" by neighboring protons. This means that the nuclear
spin of one proton causes the spin of another to resonate at different frequencies. In the simplest
case, a proton with one neighbor shows up as a doublet (two peaks) instead of one single line.
The multiplicity of a signal is simply the number of such lines that correspond to a single proton
(or a single set of equivalent protons).

The patient is susceptive to pneumococcal bacteremia while she was t.pdf
The patient is susceptive to pneumococcal bacteremia while she was taking amoxicillin from
starting. It is showing that patient has acquired an immunity against any bacteria; if the acquire
immunity is coming from mother. May be her mother was treated against bacterium
Corynebacterium diphtheriae for Diphtheria for that an immunity against the antibiotic penicillin
or erythromycin may be developed in the bacterium. That can be happened by high dose or break
of dose or long term dose. That resistivity for bacteria is retained in mother immune system;
through suggesting penicillin or erythromycin as an antigen for body. Such immunity then
carried through mother to her and now after some time even in normal doses the susceptibility
has developed for pneumococcus bacterium in Wanda.

SRP Signal recognition particle. The signal recognition particle (S.pdf
SRP: Signal recognition particle. The signal recognition particle (SRP) is an abundant, cytosolic,
universally conserved ribonucleoprotein (protein-RNA complex) that recognizes and targets
specific proteins to the endoplasmic reticulum in eukaryotes and the plasma membrane in
prokaryotes (Walter, 1981). So this is notan example of a gated channel or membrane pore. So
the option ( C ) is correct.

Some of the various financial position found in most hotels areRe.pdf
Some of the various financial position found in most hotels are:
Recording Revenue- In the hospitality industry, revenue recognition is fairly straightforward. For
both restaurants and hotels, revenue is earned when the meal or the hotel stay occurs. It is
important to note that reservations often include a deposit for the first night\'s stay. As this
deposit has not yet been earned, these deposits are not revenue yet. Payments received for
deposits are considered deferred revenue until they are earned.
Costs of Sales- Major costs in the hospitality industry include costs of food and labor. Food
costs, depending on the type of restaurant or resort, can be nearly half of a company\'s expenses.
Costs of sales should be recorded in line with revenue recognized. For example, if a company
serves 2,500 hamburgers in August that cost the company $4,000 and recognized $10,000 in
revenue in August, then the cost of the hamburgers should be recognized in August as well. This
entry would be recorded as a debit to cash and a credit to revenue for $10,000, as well as a debit
to cost of sales and a credit to inventory for $4,000. Food that was unprepared as of the end of
the month remains in inventory on the balance sheet.
Operating Expenses- Non-guest and patron costs of the company are reflected in the company\'s
operating expense accounts. When operating costs are incurred the company will make a debit to
operating expenses and a credit to cash or accounts payable, depending on whether the purchase
was made via cash or credit, respectively. Common operating expenses in the hospitality
industry are rent, insurance and non-client service salary expenses.
Capital Purchases- Serving meals or taking care of hotel guests usually requires a fair amount of
equipment. Industrial linen washers, stove tops, mixers and computers are all viewed as capital
expenditures. These items, which benefit more than one accounting period, are recorded with a
debit to fixed assets and a credit to cash at the time of purchase. Over the useful life of the
equipment the item is depreciated. Depreciation entries are made with a debit to depreciation
expense and a credit to accumulated depreciation. The accumulated depreciation and the fixed
asset account offset each other on the company\'s financial statements, so the equipments\' value
is always reported as cost less accumulated depreciation.
accounting division -the hotel division responsible for keeping track of the many business
transactions that occur in the hotel and managing the hotel\'s finances.
assets - resources available for use by a business, i.e, anything owned by the business that has
monetary value
average daily rate (ADR) - a key rooms department operating ration: rooms revenue divided by
number of rooms sold, Also called average room rate
balance sheet - a financial statement that provide information on the financial position of a hotel
by showing its assets, liabilities and equity on a given date
capture rate - T.

Ques-7Viruses contain DNA (deoxyribonucleic acid) or RNA (ribonuc.pdf
Ques-7:
Viruses contain DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) as their genetic
material, and they reproduce in the host cells. Bacteriophage is a type of virus that can infect
bacteria and inject its genome into the host, the bacteria then produces dozens of viral lineages.
Retrovirus such as HIV (human immune deficiency virus) reproduces in a different way, as they
contain reverse transcriptase enzyme. In this, a complementary DNA is transcribed from the
RNA genome, and it is called as DNA provirus.
The rate of evolution in RNA-based viruses (microcosm), like HIV-1 has million times higher
mutation rate when compared to that of DNA-based organisms (bacteria humans etc). It can
rapidly changes its genome components under biological conditions to acquire adaptations for
survival (resistance against drugs, immune components) in the biological host cell medium
compared to the DNA based organisms in which lower rate of evolutionary adaptations were
observed. This property of high genomic mutation rate in HIV-1 retrovirus is due to the
following mechanisms.
Viral genome transcribe via reverse transcription finally proved HIV-1 mRNA (after splicing)
with Rev 350 nucleotide sequences. These Rev produced once the viral mRNA transferred to the
cytoplasm from the nucleus for translation. Virulence is the factor of causing extensive damage
to the host cell and infecting new host cell in which pathogen is going to undergo extensive rate
of reproduction & phase variation along with genome modification to defend host immune
system. This is the main basis of evolution and an example ahs described below.
Several mutated viral lineages are produced due to the nucleotide integration into the host cells
& change their genome finally code for the enzymatic proteins such as reverse transcriptase,
ribonuclease, and integrase in order to promote severe multiplication of integrated host genome
with viral protein predominanlty result in several lineages (multiple capies of virions).
For example: Viral evolution mechanism with new genome & producetion of several viral
lineages
1. After viral particle entry, viral genome integrates into the host cell genome and replicate
followed by expression. Later the novel synthesized viral proteins are going to be transported to
specific sites for assembly into progeny virus thereby-----> more assembly/progeny
2. Even though viral assembly is going to takes place in the host cell plasma membrane, but a
variety of viral genomes initiate assembly in intracellular organelles or nucleus predominantly.
Thereby further particle/plaque forming units associate with exocytosis of the viral and host cell
integrated genome after lysis. Finally again mature viral lineages are going to target new cells.
Reverse transcriptase induced complementary DNA synthesis followed by mRNA synthesis for
viral protein -coding repoitre. This enzyme enables to produce more viral genome particle by
integrating into the host cell followed by vir.

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.

Sodium bicarbonate (Na+HCO3- ) is mildly alkaline.pdf
- 1. Sodium bicarbonate (Na+HCO3- ) is mildly alkaline and it reacts withacids: H+ + HCO3- =H2CO3 (carbonic acid) which is unstable inwater and breaks down into water & Carbon Dioxide : H2CO3(aq) --> H2O(l) + CO2 (g) . Inan open container at atmospheric pressure, the CO2 escapes, so thereaction is irreversible. Alka Seltzer must contain some mildacid in solid form, maybe acetylsalicylic acid (aspirin). When placed in water, the acid and bicarbonate react and fizz(CO2). Bicarbonate is useful in antacids for the same reason- stomach acid (HCl) reacts with the bicarbonate producing waterand carbon dioxide. The carbon dioxide leaves (burp!) andonly water remains where there once was a strong acid.
