- Blood type O positive (O+) people have red blood cells that are not coated with antigens and their blood can be transfused to other O+ people as well as A+, B+, and AB+ people. However, O+ people can only receive blood from other O+ or O- donors.
- Blood type O negative (O-) people do not have antigens on their red blood cells and are considered "universal donors" as their blood can be transfused to people of any blood type. However, O- people can only receive blood from other O- donors.
- Only O- blood is considered a universal donor type as it can be given to anyone regardless of their blood type due to the absence of
A blood type (also called a blood group) is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs). These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system.
If a doctor talks about your blood type, usually he or she is referring to two things: your type in the ABO system and Rhesus (Rh) factor. Human blood type is determined by antigens on the red blood cells. An antigen is a structure on the cell surface that causes a human immune response reacts to if the structure is foreign to the person’s body. Consequently, blood type match is of crucial importance. The donor’s blood type is identified at the Blood Centre, and the patient’s blood type is determined before transfusion. Here is everything you need to know!

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
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.

A Strategic Approach: GenAI in EducationPeter Windle
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.

O positive (O+) or O negative (O-) blood group: what are the differences?
1. Blood group O positive
(O+) or O negative (O-):
What are the differences?
2. Summary
Blood group
O is well known to everyone. It's no coincidence that O-negative
(O-) people are called "universal donors." What does that mean?
What about O-positive (O+) people?Answers from Dr. Pascale
Richard, Medical Director of the French Blood Establishment
(EFS).
Cotton pads for periods in pakistan are made from natural cotton. Their cotton
is not organic. However, it is not bleached with chlorine, so it does
not contain any dioxins.The absorbent core is also made of natural
cotton and contains no cellulose.

4. As a reminder: Which blood groups are there?
Our blood is made up of 45 μl (red blood cells, white blood cells and
platelets) and 55% plasma (the liquid part of blood). However, the
antigens found on our blood groups vary from person to person, as do some
proteins that may or may not be present in plasma.
According to the ABO system, discovered in 1900 by the American
biologist and physician Karl Landsteiner, there are four basic blood
groups: blood group A, blood group B, blood group AB and blood
group O.By combining this system with the Rhesus system, which
determines the presence or absence of another antigen in the blood,
eight different blood groups are obtained:
5.
6. • I blood group O positive (O+). Blood group
O+ or O-: What are the differences? Who to donate blood to?
Blood Group Peculiarities Positive? Who can receive O+ blood?
The red blood cells of O+ people are not coated with an antigen on their surface.
Therefore, the blood of O+ people can be transfused into all positive blood groups (A+,
B+, AB+, O+).
O+ red blood cells can only be transfused to Rhesus positive individuals (A+, B+, AB+,
O+). Blood group O
contains anti-An and anti-B antibodies. As such, they can only obtain blood from O+
or O humans.Otherwise, their antibodies attack red blood cells of blood groups A, B,
and AB, this is called hemolysis.
7.
8. Peculiarities of blood group 0-negative? Who can receive O-Blood?
Like O+ people, O people do not have antigens on the surface of their red blood
cells. Your red blood cells can then be transfused into any blood group, regardless
of rh (A+, A-, B+, B-, AB+, AB-, O+, O-).
O-people, on the other hand, can only receive Rhesus negative blood (O-)
Which blood group is the universal donor?
Only O-negative (O-) individuals are considered “universal donors”. In other
words, you can donate anyone else's blood (A+, A-, B+, B-, AB+, AB-, O+, O-)
because their red blood cells don't contain the antigen.
O+ or O-: Which blood type is better?
9. Like O+ people, O- people have no antigens on the surface of their red blood cells
Their red blood cells can therefore be transfused to any blood group regardless of
rhesus (A+, A-, B+, B-, AB+, AB-, O+, O-).
In contrast, O- people can only receive rhesus negative (O-) O blood.
Which blood group is a universal donor?
Only people in the O negative (O-) group are considered "universal donors". In other
words, they can donate their blood from any other person (A+, A-, B+, B-, AB+, AB-, O+,
O-), because their red blood cells carry no antigen.
O+ or O-: which is the best blood group?
"There is no good or bad, no better or worse blood group, insists Dr. Richard. It is the
chance of genetics that does its work and there is no bad lottery”. Blood group O does
not have any particular advantages over blood groups A, B or AB.
