Forensic Existence of Blood as a Dynamic Evidenceijtsrd
Blood is one of the chief form of biological fluid which is recovered at the location of crime. This review article focus on blood as a prime forensic evidence which is most commonly encountered on crime scenes. The font of insipiration for the same is the variable facts and the frequent occurrence of blood as an evidence on the crime scene. The article pronounces the complete details of blood, including its composition, cell types, relation of blood to scientific science, handling liquid blood stains , wet blood stains, dried blood stains, and the post mortum blood and preservation methods followed by a detailed analysis preliminary and confirmatory test . The analysis of blood can be categorised on the basis of its physical and chemical properties. The major aim of this study is to provide all the relevant facts related to blood collection, packaging and the entire examination.

Notes of Shape and Size of RBCs, Structure of RBCs, Life Cycle of RBCs, Funct...Vamsi kumar
Red Blood Cells (RBCs) possess unique attributes essential for their function in the circulatory system. Their distinctive biconcave shape maximizes surface area for efficient gas exchange. Structurally, mature RBCs lack a nucleus, making room for hemoglobin, a molecule vital for oxygen and carbon dioxide transport. These cells undergo a lifecycle that lasts about 120 days, originating from the bone marrow and eventually being removed by the spleen. Their primary role involves ferrying oxygen to body tissues and removing carbon dioxide. Additionally, changes in RBC size, shape, or hemoglobin content can signify various medical conditions, and there are specific disorders, like anemia or sickle cell disease, that directly impact RBCs.
This presentation contain the information of the components structure and function and of the blood like ( RBC , WBC(Classifications ), Platelets , plasma )and its also Composition & Function
1) Coagulation of blood
2) Disorders of blood
The cellular components of blood are erythrocytes (red blood cells, or RBCs), leukocytes (white blood cells, or WBCs), and thrombocytes (platelets). By volume, the RBCs constitute about 45% of whole blood, the plasma about 54.3%, and white blood cells about 0.7%. Platelets make up less than 1%.

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.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
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.

Transports essential nutrients and other related functions.
Regulates body temperature.
Takes part in the regulation of water balance in the body.
2. Name the formed elements in the blood.
Ans:
The formed elements in the blood are platelets, red blood cells and

The fluid portion of the blood is plasma.
4. How may blood plasma be separated from formed elements?
Ans:
5. How may clotting of the blood be prevented?
Ans:
The clotting of the blood can be prevented by using clot busters such as
anti-coagulants, removal of the clot or thrombectomy and catheter.
6. What is the difference between arterial blood and venos blood?
Ans:
7. What is the physiological importance of the blood?
Ans:
Blood has a high water content which is needed for maintaining blood
pressure, heat regulation and osmotic condition. It sometimes called as the river
of life in which the body is very much dependent just like the other important
parts.
2. Biochemistry: Blood 2013
8. How are red blood cells formed? Give the composition of the red blood cells.
Ans:
The red blood cells or the erythrocytes are formed in the bone marrow.
It is composed of 45% of the volume of the blood and is responsible for the
opacity of the color of it.

Ans:
10. What is leukemia? Leucopenia?
Ans:
Leukemia is an acute and chronic disease characterized by a gross
proliferation of leucocytes which crowd into the bone marrow, spleen, lymph
nodes and etc. It has an increase of WBC count. On the other hand,
Leucopenia is the abnormal reduction in WBC in the blood.
