It explains the main uses of each punctuation mark and provides examples of proper usage. Common mistakes involving certain punctuation marks are also highlighted.
The document provides guidance on proper punctuation usage. It discusses the full stop (period), comma, colon, and semicolon. For commas, it describes four uses: listing, joining, gapping, and bracketing. Listing commas are used like "and" in a list. Joining commas join two sentences when followed by "and", "or", "but", etc. Gapping commas show omitted repeated words. Bracketing commas set off weak interruptions. Colons introduce an explanation of the preceding statement. Semicolons join closely related sentences without a connecting word.
The document provides guidance on proper punctuation usage:
1. The full stop is used to end declarative sentences. Common errors include punctuating two complete statements with only a comma instead of a full stop.
2. Commas are used in lists, to join two sentences together using connecting words like "and", and to show omitted words. Bracketing commas set off weak interruptions.
3. Colons introduce an explanation of the preceding statement. Semicolons join closely related complete sentences without a connecting word.
The document provides information on various grammar topics including parts of speech, modifiers, tenses, and clauses. It discusses proper use of nouns as modifiers, adverbs, conjunctions, prepositions, verb tenses, mood, attributes, and relative clauses to improve clarity and effectiveness in writing.

Martinez 1 Quotation Integration Every time you.docxAASTHA76
This document provides guidance on properly integrating quotations into academic writing. It begins by stating that quotations must be signaled and explains the basic punctuation rules for introducing quotations, such as using commas with introductory phrases and colons with complete introductory sentences. The document then describes three main ways to integrate quotations: with a dependent clause and comma, with a colon and independent clause, or by making the quotation part of the writer's own sentence. It provides examples of each and notes that MLA style requires explaining quotations in the writer's own words while APA style does not. The document concludes by discussing how to avoid plagiarism when quoting and paraphrasing.
The semicolon has two main uses: to connect two independent clauses and to serve as a "super comma" when items in a list already contain commas. It can also be used in a few minor situations, such as introducing a list preceded by a connecting word or joining two sentences connected by a conjunction when the first sentence already contains commas. Mastering the two primary uses of connecting independent clauses and serving as a super comma will allow you to use semicolons correctly in most situations.

It discusses the purpose and use of various punctuation marks including periods, commas, colons, question marks, apostrophes, dashes, quotation marks, hyphens, and capitalization. Key points covered include using periods to end sentences and abbreviations, commas to separate elements in a list or introduce phrases, colons before lists, question marks with interrogative sentences, and capitalization of proper nouns and the first word of sentences.
This document discusses various statistical concepts including outliers, transforming data, normalizing data, weighting data, robustness, and homoscedasticity and heteroscedasticity. Outliers are values far from other data points and should be carefully examined before removing. Data can be transformed using logarithms, square roots, or other functions to better fit a normal distribution or equalize variances between groups. Normalizing data puts variables on comparable scales. Weighting data adjusts for under- or over-representation in samples. Robust tests are resistant to violations of assumptions. Homoscedasticity refers to equal variances between groups while heteroscedasticity refers to unequal variances.
The document provides an overview of correlation, regression, and other statistical methods. It defines correlation as measuring the association between two variables, while regression finds the best fitting line to predict a dependent variable from an independent variable. Simple linear regression uses one predictor variable, while multiple linear regression uses two or more. Logistic regression is used for nominal dependent variables. Nonlinear regression fits curved lines to nonlinear data. The document provides examples and guidelines for choosing the appropriate statistical test based on the type of variables.
This document provides an overview of various statistical tests for comparing variables, including t-tests, ANOVA, MANOVA, ANCOVA, and MANCOVA. It defines each test and provides examples of their proper usage. T-tests are used to compare two groups on a continuous variable, including paired and unpaired, parametric and non-parametric versions. ANOVA and MANOVA are used to compare three or more groups and two or more dependent variables, respectively. ANCOVA and MANCOVA control for covariates/confounding variables in one-way and two-way designs with single or multiple dependent variables. Examples and best practices are given for selecting and conducting each type of test.
This document discusses key concepts in applied statistics including hypothesis testing, p-values, types of errors, sensitivity and specificity. It provides examples and explanations of these topics using scenarios about testing if feeding chickens chocolate changes the gender ratio of offspring. Hypothesis testing involves defining the null and alternative hypotheses and using a statistical test to either reject or fail to reject the null hypothesis based on the p-value. Type I and type II errors in hypothesis testing are explained. Sensitivity and specificity in diagnostic tests are introduced using an example about detecting if a car is being stolen.
This document provides an introduction to applied statistics and various statistical concepts. It discusses the normal (Gaussian) distribution, standard deviation, standard error of the mean, and confidence intervals. Examples and explanations are provided for each concept. Hands-on examples for calculating these statistics in Excel, SPSS, and Prism are also presented. The document aims to explain key statistical terms and how they are applied in data analysis.

HMG-CoA reductase inhibitors, commonly known as statins, are the primary drugs used to treat dyslipidemia. They work by inhibiting cholesterol production in the liver, leading to increased clearance of LDL cholesterol from the bloodstream. Fibrates also effectively lower triglyceride levels by increasing fatty acid metabolism. Bile acid sequestrants function by binding bile acids in the gut, enhancing their excretion and increasing LDL receptor activity in the liver. Combination drug therapies that target multiple lipid abnormalities can provide improved treatment outcomes over single agents alone.
This document discusses various immunopharmacology drugs and their uses. It covers immunosuppressive antibodies including monoclonal antibodies used for transplantation, cancer, and autoimmune diseases. It also discusses immunosuppressive drugs classified as immunophilin ligands or cytotoxic agents that are used for transplantation and graft-versus-host disease. Common drugs discussed include cyclosporine, tacrolimus, sirolimus, mycophenolate, azathioprine, and cyclophosphamide.
The document provides guidance on rational prescription writing, including introducing the concept of "P-drugs" or personal first-choice drugs, outlining the steps in prescription writing, common abbreviations, and important instructions and information to provide to patients. It also discusses medication errors and how electronic prescribing can help reduce errors by suggesting alternative drugs. The overall goal is to teach students how to properly treat patients through skillful prescribing rather than just knowledge of drugs.
This document discusses the use of various drugs during pregnancy and lactation. It covers analgesics, antihypertensives, chemotherapeutics, central nervous system drugs, anticoagulants, endocrine drugs, antiemetics, antihistamines, and others. For each drug class or individual drug, it notes any potential risks to the fetus, such as teratogenicity, and recommendations for use during pregnancy and effects on the newborn. The overall message is that many drugs should be avoided during pregnancy if possible due to risks of harming fetal development, and careful consideration of risks and benefits is needed for drug treatment during this period.
This document discusses drug use during pregnancy and lactation. It covers principles of therapy during pregnancy and lactation, emphasizing using the lowest effective dose for shortest time. Physiologic and pharmacokinetic changes in pregnancy that affect drug distribution and metabolism are described. The fetal circulation is explained, as well as how drugs can affect the fetus. Drug categories in pregnancy from A to X are defined based on safety evidence. Common issues in pregnancy like anemia, constipation, and gestational diabetes are also covered.

It concludes with guidance on drug use during lactation, identifying drugs that are generally safe and those that require caution.
This document discusses methemoglobinemia, which is a condition caused by elevated levels of methemoglobin in the blood. Methemoglobin cannot carry oxygen, so symptoms range from cyanosis to death depending on levels. It may be congenital or acquired through medications, chemicals, and certain foods. Diagnosis involves blood tests showing abnormal hemoglobin color. Treatment focuses on reducing methemoglobin back to hemoglobin, primarily using methylene blue or ascorbic acid. The document also briefly covers cyanide poisoning, which causes tissue anoxia and can be fatal within minutes of inhalation.

Cómo hemos implementado semántica de "Exactly Once" en nuestra base de datos ...javier ramirez
Los sistemas distribuidos son difíciles. Los sistemas distribuidos de alto rendimiento, más. Latencias de red, mensajes sin confirmación de recibo, reinicios de servidores, fallos de hardware, bugs en el software, releases problemáticas, timeouts... hay un montón de motivos por los que es muy difícil saber si un mensaje que has enviado se ha recibido y procesado correctamente en destino. Así que para asegurar mandas el mensaje otra vez.. y otra... y cruzas los dedos para que el sistema del otro lado tenga tolerancia a los duplicados.
QuestDB es una base de datos open source diseñada para alto rendimiento. Nos queríamos asegurar de poder ofrecer garantías de "exactly once", deduplicando mensajes en tiempo de ingestión. En esta charla, te cuento cómo diseñamos e implementamos la palabra clave DEDUP en QuestDB, permitiendo deduplicar y además permitiendo Upserts en datos en tiempo real, añadiendo solo un 8% de tiempo de proceso, incluso en flujos con millones de inserciones por segundo.
Además, explicaré nuestra arquitectura de log de escrituras (WAL) paralelo y multithread. Por supuesto, todo esto te lo cuento con demos, para que veas cómo funciona en la práctica.

How We Added Replication to QuestDB - JonTheBeachjavier ramirez
Building a database that can beat industry benchmarks is hard work, and we had to use every trick in the book to keep as close to the hardware as possible. In doing so, we initially decided QuestDB would scale only vertically, on a single instance.
A few years later, data replication —for horizontally scaling reads and for high availability— became one of the most demanded features, especially for enterprise and cloud environments. So, we rolled up our sleeves and made it happen.
Today, QuestDB supports an unbounded number of geographically distributed read-replicas without slowing down reads on the primary node, which can ingest data at over 4 million rows per second.
In this talk, I will tell you about the technical decisions we made, and their trade offs. You'll learn how we had to revamp the whole ingestion layer, and how we actually made the primary faster than before when we added multi-threaded Write Ahead Logs to deal with data replication. I'll also discuss how we are leveraging object storage as a central part of the process. And of course, I'll show you a live demo of high-performance multi-region replication in action.

4. Avoid Adjectives to Describe Your Work
Don’t use adjectives to describe your work: striking
results, very significant coefficients.
If the work merits adjectives, the world will give
them to you.
Do not use double adjectives. Results are certainly
not “very novel”.
Do not contract verb forms: don’t, or can’t, use the
full form: do not, cannot.
5. Avoid Negatives
Avoid negatives (Negatives can be used for particular
emphasis, and for correcting misconceptions).
Avoid abbreviations.
Avoid overloading the text with references, it is better
to cite only the more recent papers.
Place sequences in order similarly, it is best to describe
procedures in the order that they take place.
6. Avoid Long Sentences and Paragraphs
Sentences should vary in lengths.
As a rule of thumb:
Sentences less than 20 words long are probably
fine.
Sentences 20 to 30 words long are probably
satisfactory.
Sentences 30 to 40 words long are suspect.
Sentences with over 40 words may need re-
writing.
7. Avoid Long Sentences and Paragraphs
Use short paragraphs.
Print out and revise/edit draft copies.
Think about global revisions; re-sequencing major
portions, and local revisions.
If it is difficult to explain something, try saying it and
write this down.
8. Avoid Clusters of Nouns
Do not use clusters of nouns and avoid
expressions like: “chemical healing suppression”
Say instead:
“Suppression of healing by chemicals”, or
“Suppression of chemical healing”.
Use prepositions to make your meaning clear.
9. Avoid Adjectival Clauses
Do not use Adjectival clauses:
Instead of writing: “an innovation based return on
investment culture”,
Say: “a culture of innovation based on return-on-
investment”.
Again, use prepositions to make your meaning
clear, even if this construction is longer.
10. Avoid Filler Verbs
Do not use filler verbs.
Do not write: “We conducted a study of group
compounds”
Say: “We studied group compounds”.
Examples of dummy-verbs to be avoided are “to
be present”, “to occur”, “to perform”, “to obtain”.
11. Avoid Imprecise Words
Do not use imprecise words like “quite”, “some”,
“considerable”, “a great deal”, .
Be as precise as possible when dealing with facts or
figures.
Avoid phrases such as: about a hundred years ago.
If estimation is necessary, use approximately rather
than about.
12. Avoid Nouns Instead of the Verbs
Do use nouns instead of the verbs from which
they are derived.
Avoid writing: “Recording of pulse rates was
made”;
Instead write: “Pulse rates were recorded”. Do use
nouns instead of the verbs
13. Avoid “That”!
Most good writers say that everything before the
“that” may be deleted!
“It should be noted that” is particularly obnoxious.
Just say what you want to say!
Search for “that” in the document to get rid of them.
14. Avoid “That”!
Do not begin sentences with constructions like
“Despite the fact that …”, “Notwithstanding the fact
that …”.
Compare these two versions:
Thus, although there were too few plots to show all
of the interactions which we sought, under the
conditions of the experiment, copper and zinc
acted additively.
Thus, copper and zinc acted additively under the
conditions of our experiment.

17. Avoid “Naked This”!
Clothe the naked “this”:
“This shows that markets really are irrational”
This what? What shows the markets are
irrational?
“This” should always have something following
it: “This regression shows that....” is fine.
Often there are three or more things in recent
memory of readers that “this” could point to.
18. Avoid Colloquial Vocabulary
Do not use colloquial vocabulary: kids, boss.
Instead use: children, manager.
Avoid these:
like for introducing examples;
use: such as or for instance.
Thing, nothing or something;
use: factor, issue or topic.
lots of;
use: a significant/considerable number.
19. Avoid Colloquial Vocabulary
Avoid the following:
little/big;
use: small/large.
‘get’ phrases such as: get better/worse;
Use improve and deteriorate.
good/bad are simplistic;
use: positive/negative (e.g. the changes had several
positive aspects).
20. Avoid Question Forms
Do not use question forms such as: Why did war
break out in 1914?
Instead, use: There were three reasons for the
outbreak of war.
Avoid numbering sections of your text, except in
reports and long essays.
Use conjunctions and signposting expressions to
introduce new sections (Turning to the question of
detecting cancer . . .).
21. Space
Use a space before and after numbers, and symbols
related to numbers:
a 6 h experiment.
a 37 ⁰C water (NOT “37⁰ C” , the angles are
exceptions, and “a 60⁰ angle” is correct).
a 6.2 mm pipe.
3 > 1 (not: 3>1)
4 < 6 (not: 4<6)
5 ± 8 (not: 5±8)
x = 3 (not: x=3)
Percent sign (%) is an exception: 25% (not: 25 %)
22. A or AN?
Pay attention to the “sound” not to dictation”
An hour (not: a hour)
An umbrella
A university
An MP3 player (NOT: a MP3 player)
An FDA approved drug (NOT: a FDA approved
drug)
23. The
In general, the is used with:
Superlatives (the fastest)
Time periods (the eighteenth century, the 1970s)
Unique things (the government, the world)
Specified things (the French Revolution)
Regular publications (the New Scientist)
Regions, rivers, seas, oceans, deserts (the south, the River Seine)
Very well-known people and things (the Spanish artist)
Institutions and bodies (the United Nations)
Bridges, highways, buildings, museums, galleries
Currencies (the euro), Positions (the middle)
24. The
“The” is NOT used with:
Things in general (bad results)
Names of countries (except for the UK, the USA and
a few others)
places named after people (Heathrow Airport)
Streets, weekdays, month names, mountains, parks,
lakes
25. The
“The” is NOT used with:
Abstract (uncountable) nouns eg:
Pollution is a problem. OK, general fact.
The pollution in my town is a problem. OK,
specific location
There is a pollution in my town. NOT OK,
uncountable noun.
Note the alternate forms:
Australia’s deserts are expanding.
The deserts of Australia are expanding.
27. Comma (,)
Comma use is partly a matter of individual style.
It is useful to think of commas as providing a brief
pause for readers.
A pair of commas may delimit the beginning and end
of a phrase.
Overuse can slow down the reader, but equally a lack
of commas can be confusing.
28. Comma (,)
Comma is used:
After introductory words:
However, more cases should be considered before
reaching a conclusion.
Around examples or comments:
Certain crops, for instance wheat, are susceptible
to diseases.
Nationalism, it is widely recognized, has a positive
and negative side.
29. Comma (,)
Comma is used:
In lists:
Tomatoes, beans, cabbages, and potatoes were all
genetically modified in turn.
Before conjunctions (and, but, for, or, nor, so,
yet):
Three hundred people were interviewed, but only
half the responses could be used.
36. And
Insert and before the last item in lists:
The main side effects were fever, anemia, and
seizure.
In compound sentences, “and” acts as equal
sign in mathematics (=), so the 2 sides should
be the same:
He drives fast and careless (wrong sentence!)
37. Connectors
The usual form of writing is:
First clause; connector, second clause (when
the connector is at the middle of the sentence)
. Connector, first clause (when the
connector is at the beginning of the sentence)
42. Connectors
Emotion (do not use in academic writing)
Fortunately/ Unfortunately
Interestingly
Justifiably
Surprisingly
43. Apostrophe (’)
Apostrophe shows contractions (not common in
academic English)
It is used with possessives:
The professor’s secretary (singular)
Students’ marks (plural words ending in ‘s’)
Women’s rights (for irregular plurals)
44. Semicolon (;)
Semicolons are used when a comma would be too
weak and a full stop too strong:
20 people were interviewed for the first study; 33
for the second.
Nobody questioned the results; they were quite
conclusive.
The semi-colon separates segments of a sentence that
are “further apart” in position, or meaning, but are
related.
45. Semicolon (;)
If the ideas were “closer together”, a comma is used.
Semicolons separate two clauses that may stand on
their own, but are too closely related for a colon or
full stop.
Semicolons are also used to divide up items in a list
when they have a complex structure, as in a multiple
citation:
(Maitland, 2006; Rosenor, 1997; New Scientist,
2006b; University of Michigan, 2000).
46. Colon (:)
To introduce explanations: The meeting was
postponed: the Dean was ill.
To start a list: Three aspects were identified:
financial, social and ethical.
To introduce a quotation: As he said: ‘You can
never be too rich or too thin.’
48. Hyphen (-)
Hyphens are used with compound nouns, and certain
structures:
A well-researched, thought-provoking book.
Her three-year-old daughter is learning to read.
Hyphens are used for compound modifiers before the
noun:
After-tax income
Risk-free rate
Two-day return
Three-digit code
Value-weighted index
49. Hyphen (-)
Hyphen is not used when part of the compound
modifier is an adverb ending in ‘ly’:
Previously acquired subsidiary
Equally weighted index
Publicly traded stock
Consider the difference:
Diameter of the dish is 35 mm. (“35 mm” is a noun)
Cells were grown in 35-mm dishes. (“35-mm” is an
adjective)
For concentrations hyphen is NOT used; eg: a 50 mg
(NOT: 50mg) buffer.
50. Hyphen (-)
Hyphenate two consecutive modifiers:
The Ca2+- and phospholipid-dependent enzyme PKC…
The epinephrine- and isoproterenol-induced responses
were…
The drug-sensitive and -insensitive cells were compared
for…
The suspended compound
first- and second-class fares
high- and low-pressure turbine
interest- or revenue-producing schemes
short- and long-term plans
two-, four- and six-meter widths
51. Full stop (.)
They are used with certain abbreviations, when they
are the first part of a word: govt./Jan./p. 397
But do not use full stops with acronyms such as:
BBC/UN/VIP
If the sentence is in question or exclamation form,
then it ends with a question mark or exclamation
mark.
The full stop is also used to terminate abbreviations
like etc., e.g., et al., but not with abbreviations for SI
units.
52. Where, In which
“Where” refers to a place. “In which” refers to a
model.
Wrong: “models where consumers can trust to,”
Correct: “models in which consumers can trust to,”
53. Introduce Examples
For instance, for example (with commas):
Some car manufacturers, for instance Kia, now offer
seven-year guarantees.
Such as, e.g. :
Many successful businessmen such as Bill Gates have
no formal qualifications.
Particularly, especially (to give a focus):
Certain Master’s courses, especially American ones,
take two years.
54. Introduce Examples
A case in point (for single examples):
A few diseases have been successfully eradicated. A
case in point is smallpox.
Some phrases are used when there is only one
‘example’, brackets may also be used for this
purpose.
This group consists of: in other words, namely, that is
(to say), i.e.
The organ which does not need insulin for using
glucose, namely brain….
55. Problems and Solutions
Three main difficulties have
arisen: a)…
The main challenge faced by
nurses is…
One of the concerns during
the attack is…
The new process created two
questions: …
The team faced six issues:
1)…
Our principal worry/dilemma
was…
The best remedy for this
may be…
Two answers have been
put forward: firstly…
Another suggestion is…
The second proposal
was finally accepted.
This was rectified/
solved by…
56. Comparison
Comparisons can be modified by the use of adverbs.
Adverbs such as: slightly, marginally, approximately,
considerably, significantly and substantially:
Example:
substantially larger than…,
slightly smaller than…,
significantly colder than….
57. Comparison
Similarity can be noted by the use of “as . . . as” or
“the same as”:
The prevalence of the disease in men is
approximately the same as the prevalence in
women.
Mortality rate in Iran, is as high as in Pakistan.
This form can be used for quantitative comparison:
Nucleolus is half as large as nucleus.
(also twice as large as . . ., ten times as fast as . . .)
58. Comparison
When using superlatives, take care to define the
group (e.g. ‘the longest cell’ has no meaning):
The longest cell in the muscle tissue/in the body.
the most/the least are followed by an adjective:
The most interesting example is. . .
the most/the fewest are used in relation to numbers:
The fewest stem cells differentiated (i.e. the lowest
number).
59. Cause and Effect
A writer may choose to emphasize either the
cause or the effect.
In both cases, either a verb or a conjunction can
be used to show the link.
62. Cause and Effect
Compare the following:
Because children were vaccinated, diseases
declined (because + verb)
Because of the vaccination, diseases declined
(because of + noun)
As/since children were vaccinated, diseases
declined (conjunction + verb)
Owing to/due to the vaccination, diseases declined
(conjunction + noun)
63. Cause and Effect
Conjunctions are commonly used with specific
situations, while verbs tend to be used in general.
Cases:
Printing money commonly leads to inflation (general)
Due to hot weather, demand for ice cream increased
(specific)
Note the position of the conjunctions in the
following:
The drug was arrhythmogenic, therefore / hence / so
/ consequently the patient die.
64. Passive Form
The passive should not be overused.
The passive is used when the writer wants to focus on
the result, not on the cause:
The supernatant was injected into cells.
Dr. Moosavi injected the supernatant into cells.
So the passive is used when the cause (a person or
thing) is less important or unknown.
65. Passive Form
The passive is also used in written work to provide a
more impersonal style:
The findings were evaluated. (not: ‘I evaluated the
findings’)
An adverb can be inserted in a passive form to add
information:
This process is commonly called ‘depolarization
blockade’.
66. Singular or Plural?
Nouns should agree with verbs, and pronouns with
nouns:
Those problems are unique
Uncountable nouns and irregular plurals usually have
no final ‘s’:
Most students receive free tuition.
The main export is tropical fruit.
67. Singular or Plural?
General statements normally use the plural:
State hospitals have lower fees.
Each/every are followed by singular noun and verb:
Every student gets financial support.
Two linked nouns should agree:
Both the similarities and differences are important.

75. Numbers
Both fractions (1⁄2) and decimals (0.975) may be
used.
There is no final ‘s’ on hundred / thousand / million
used with cardinal numbers:
Six million people live there.
But:
Thousands of people were killed.
Rates are expressed as percentages (e.g. the literacy
rate rose to 75%), but may also be per thousand (e.g.
the Austrian birth rate is 8.7).
76. Numbers
It is normal to write cardinal numbers as words
from one to ten and as digits above ten:
There were 12 metastases in the body, but only three
needed surgical removal.
If the actual number is not important, words such
as various, dozens or scores may be used instead:
The snowstorm closed 47 schools.
The snowstorm closed dozens of schools.
77. Numbers
Simplify as much as possible, compare the following
sentences:
The course fees rose from $1,200 to $2,500 from
2008 to 2010.
The course fees doubled in two years.
If appropriate, roughly / approximately (but not
about) can be added:
The course fees roughly doubled in two years.
78. Numbers
To avoid numerical precision in this sentence:
“52% of the images were classified”,
Do not say:
“the majority of the images were classified”
Say instead:
“Slightly over half the images were classified”.
