Mumbai University

The University of Mumbai, informally known as Mumbai University (MU) (formerly known as University of Bombay) is a collegiate public state university located in Mumbai, Maharashtra. It offers bachelors, masters and Doctoral courses, as well as diplomas and certificates in many disciplines like the Arts, Commerce, Science, Medical and Engineering. The language of instruction for most courses is English.

The University of Mumbai was established in 1857. The university has two campuses across Mumbai (Kalina Campus and Fort Campus) and two outside Mumbai, one of them being Thane Sub Campus. The Fort campus carries out administrative work only. Several institutes in Mumbai previously affiliated to the university are now autonomous institutes or universities.

The University of Mumbai is one of the largest universities in the world  The university in 2013 had 711 affiliated colleges.  Ratan Tata is the appointed head of Mumbai University's advisory council. 
In accordance with "Wood's despatch", drafted by Sir Charles Wood in 1854, The University of Bombay was established in 1857 after presentation of a petition from the Bombay Association to the British colonial government in India. The University of Mumbai was modeled on similar universities in the United Kingdom, specifically the University of London.  :188

The first departments established were the Faculty of Arts at Elphinstone College in 1835 and the Faculty of Medicine at Grant Medical College in 1845. Both colleges existed before the university was founded and surrendered their degree-granting privileges to the university. The first degrees awarded in 1862 were Bachelor of Arts and Licentiate in Medicine. 
Initially, the Town Hall in Mumbai was used as the university's offices.

Cornelia Sorabji, who later studied law at Somerville College becoming Oxford's first female law student and India's first female advocate, was the university's first female graduate in 1888. 

Until 1904, the university only conducted examinations, awarded affiliations to colleges, developed curricula and produced guidelines for colleges developing curricula.  Teaching departments, research disciplines and post-graduate courses were introduced from 1904 and several additional departments were established. After India achieved independence in 1947, the functions and powers of the university were re-organised under The Bombay University Act of 1953  The name of the University was changed from University of Bombay to University of Mumbai in 1996. 

In 1949, student enrollment was 42,272 with 80 affiliated colleges. By 1975, these numbers had grown to 156,190 and 114 respectively

UAE

UAE

The United Arab Emirates (UAE; Arabic: الإمارات العربية المتحدة‎ al-ʾImārāt al-ʿArabīyyah al-Muttaḥidah), sometimes simply called the Emirates (Arabic: الإمارات‎ al-ʾImārāt), is a sovereign state in Western Asia at the northeast end of the Arabian Peninsula on the Persian Gulf, bordering Oman to the east and Saudi Arabia to the south and west, as well as sharing maritime borders with Qatar to the west and Iran to the north. The sovereign absolute monarchy is a federation of seven emirates consisting of Abu Dhabi (which serves as the capital), Ajman, Dubai, Fujairah, Ras Al Khaimah, Sharjah and Umm Al Quwain. Their boundaries are complex, with numerous enclaves within the various emirates.  Each emirate is governed by a ruler; together, they jointly form the Federal Supreme Council. One of the rulers serves as the President of the United Arab Emirates.  In 2013, the UAE's population was 9.2 million, of which 1.4 million are Emirati citizens and 7.8 million are expatriates. 

Human occupation of the present UAE has been traced back to the emergence of anatomically modern humans from Africa some 124,000 BCE through finds at the Faya-2 site in Mleiha, Sharjah. Burial sites dating back to the Neolithic Age and the Bronze Age include the oldest known such inland site at Jebel Buhais. Known as Magan to the Sumerians, the area was home to a prosperous Bronze Age trading culture during the Umm Al Nar period, which traded between the Indus Valley, Bahrain and Mesopotamia as well as Iran, Bactria and the Levant. The ensuing Wadi Suq period and three Iron Ages saw the emergence of nomadism as well as the development of water management and irrigation systems supporting human settlement in both the coast and interior. The Islamic age of the UAE dates back to the expulsion of the Sasanians and the subsequent Battle of Dibba. The UAE's long history of trade led to the emergence of Julfar, in the present-day emirate of Ras Al Khaimah, as a major regional trading and maritime hub in the area. The maritime dominance of the Persian Gulf by Emirati traders led to conflicts with European powers, including the Portuguese Empire and the British Empire.

Following decades of maritime conflict, the coastal emirates became known as the Trucial States with the signing of the General Maritime Treaty with the British in 1820 (ratified in 1853 and again in 1892), which established the Trucial States as a British Protectorate. This arrangement ended with independence and the establishment of the United Arab Emirates on 2 December 1971, immediately following the British withdrawal from its treaty obligations. Six emirates joined the UAE in 1971, the seventh, Ras Al Khaimah, joined the federation on 10 February 1972. 

Islam is the official religion and Arabic is the official language of the UAE. The UAE's oil reserves are the sixth-largest in the world while its natural gas reserves are the world's seventh-largest.  Sheikh Zayed, ruler of Abu Dhabi and the first President of the UAE, oversaw the development of the Emirates and steered oil revenues into healthcare, education and infrastructure. The UAE's economy is the most diversified in the Gulf Cooperation Council, while its most populous city of Dubai is an important global city and international aviation and maritime trade hub. Consequently, the country is much less reliant on oil and gas than in previous years and is economically focusing on tourism and business. The UAE government does not levy income tax although there is a system of corporate tax in place and Value Added Tax at 5% was established in 2018 

The UAE's rising international profile has led to it being recognised as a regional and a middle power.  It is a member of the United Nations, the Arab League, the Organisation of Islamic Cooperation, OPEC, the Non-Aligned Movement and the Gulf Cooperation Council.

The land of the Emirates has been inhabited for thousands of years. Stone tools recovered from Jebel Faya in the emirate of Sharjah reveal a settlement of people from Africa some 127,000 years ago and a stone tool used for butchering animals discovered at Jebel Barakah on the Arabian coast suggests an even older habitation from 130,000 years ago.  There is no proof of contact with the outside world at that stage, although in time lively trading links developed with civilisations in Mesopotamia, Iran and the Harappan culture of the Indus Valley. This contact persisted and became wide-ranging, probably motivated by the trade in copper from the Hajar Mountains, which commenced around 3,000 BCE.  Sumerian sources talk of the UAE as home to the 'Makkan' or Magan people. 

There are six major periods of human settlement with distinctive behaviours in the UAE before Islam, which include the Hafit period from 3,200-2,600 BCE; the Umm Al Nar culture spanned from 2,600-2,000 BCE, the Wadi Suq people dominated from 2,000–1,300 BCE. From 1,200 BC to the advent of Islam in Eastern Arabia, through three distinctive Iron Ages (Iron Age 1, 1,200–1,000 BC; Iron Age 2, 1,000–600 BC and Iron Age 3 600–300 BC) and the Mleiha period (300 BC onward), the area was variously occupied by Achaemenid and other forces and saw the construction of fortified settlements and extensive husbandry thanks to the development of the falaj irrigation system.

In ancient times, Al Hasa (today's Eastern Province of Saudi Arabia) was part of Al Bahreyn and adjoined Greater Oman (today's UAE and Oman). From the second century AD, there was a movement of tribes from Al Bahreyn towards the lower Gulf, together with a migration among the Azdite Qahtani (or Yamani) and Quda'ah tribal groups from south-west Arabia towards central Oman.

Tick

Tick

Ticks (Ixodida) are arachnids, typically 3 to 5 mm long, part of the superorder Parasitiformes. Along with mites, they constitute the subclass Acari. Ticks are external parasites, living by feeding on the blood of mammals, birds, and sometimes reptiles and amphibians. Ticks evolved by the Cretaceous period, the most common form of fossilisation being amber immersion. Ticks are widely distributed around the world, especially in warm, humid climates.

Almost all ticks belong to one of two major families, the Ixodidae or hard ticks, and the Argasidae or soft ticks. Adults have ovoid or pear-shaped bodies, which become engorged with blood when they feed, and eight legs. In addition to having a hard shield on their dorsal surfaces, hard ticks have a beak-like structure at the front containing the mouthparts, whereas soft ticks have their mouthparts on the underside of their bodies. Both families locate a potential host by odour or from changes in the environment.

Ticks have four stages to their lifecycle, namely egg, larva, nymph, and adult. Ixodid ticks have three hosts, taking at least a year to complete their lifecycle. Argasid ticks have up to seven nymphal stages (instars), each one requiring a blood meal. Because of their habit of ingesting blood, ticks are vectors of many diseases that affect humans and other animals.
Mites and nematodes feed on ticks, which are also a minor nutritional resource for birds. More importantly, they carry diseases as the primary hosts of pathogens such as spirochaetes, and without their agency, the organisms could not reach their secondary hosts. The diseases caused may debilitate their victims, and ticks may thus be assisting in controlling animal populations and preventing overgrazing. 

Certain infectious diseases of humans and other animals can be transmitted by ticks, with the species of tick involved tending to be those with a wide host range. Spread of disease in this way is enhanced by the extended time during which a tick remains attached, during which time the mobile host can be carried long distances, or in the case of bird hosts, across the sea. The infective agents can be present not only in the adult tick, but also in the eggs produced plentifully by the females. Many tick species have extended their ranges as a result of the movements of people, their pets, and livestock. With increasing participation in outdoor activities such as wilderness hikes, more people and their dogs may find themselves exposed to attack.

Tick-borne virus

Tick-borne virus

Tick-borne diseases, which afflict humans and other animals, are caused by infectious agents transmitted by tick bites. They are caused by infection with a variety of pathogens, including rickettsia and other types of bacteria, viruses, and protozoa. Because individual ticks can harbor more than one disease-causing agent, patients can be infected with more than one pathogen at the same time, compounding the difficulty in diagnosis and treatment. 16 tick-borne diseases of humans are known, of which four have been discovered since 2013.

As the incidence of tick-borne illnesses increases and the geographic areas in which they are found expand, health workers increasingly must be able to distinguish the diverse, and often overlapping, clinical presentations of these diseases. Several high-profile deaths have been caused by the tick–human transmission of disease, including the death of former Senator Kay Hagan in the United States in 2019 at the age of 66. 
In general, specific laboratory tests are not available to rapidly diagnose tick-borne diseases. Due to their seriousness, antibiotic treatment is often justified based on clinical presentation alone.
