Context paragraphs:
Hasibul Hossain: Mohammad Hasibul Hossain (Bengali: মোহাম্মদ হাসিবুল হোসেন ) (born June 3, 1977, Barlekha, Sylhet Division, Bangladesh), known as Hasibul Hossain, played five Tests (2000–01) and 32 one-day internationals (1995–2004) for Bangladesh.

Kervaire invariant: The Kervaire invariant is an invariant of a framed (4"k"+2)-dimensional manifold that measures whether the manifold could be surgically converted into a sphere.  This invariant evaluates to 0 if the manifold can be converted to a sphere, and 1 otherwise.  This invariant was named after Michel Kervaire who built on work of Cahit Arf.

Arf invariant of a knot: In the mathematical field of knot theory, the Arf invariant of a knot, named after Cahit Arf, is a knot invariant obtained from a quadratic form associated to a Seifert surface.  If "F" is a Seifert surface of a knot, then the homology group H("F", Z/2Z) has a quadratic form whose value is the number of full twists mod 2 in a neighborhood of an imbedded circle representing an element of the homology group.  The Arf invariant of this quadratic form is the Arf invariant of the knot.

Imam Hossain: Mohammad Imam Hossain (born January 5, 1984) is a Bangladeshi sport shooter.  Hossain represented Bangladesh at the 2008 Summer Olympics in Beijing, where he competed for the men's 10 m air rifle.  He placed forty-sixth out of fifty-one shooters in the qualifying rounds, with a score of 581 points.

Hasse–Arf theorem: In mathematics, specifically in local class field theory, the Hasse–Arf theorem is a result concerning jumps of the upper numbering filtration of the Galois group of a finite Galois extension.  A special case of it when the residue fields are finite was originally proved by Helmut Hasse, and the general result was proved by Cahit Arf.

Mohammad Al-Emlah: Mohammad Samir Yusuf Al-Emlah is a Jordanian football player, who currently plays as an attacking midfielder for Shabab Al-Ordon and Jordan U-23.

Rajshahi City Corporation: Rajshahi City Corporation (Bengali: রাজশাহী সিটি কর্পোরেশন - in short: RCC), established in 1976, is one of the major divisional city corporations of Bangladesh.  Before its establishment as city corporation, it was a municipal corporation.  Current mayor of RCC is Mohammad Mosaddek Hossain Bulbul preceded by A. H. M. Khairuzzaman Liton who was in power for 5 years (2008–2013).  Mohammad Mosaddek Hossain Bulbul was elected as Mayor defeated Liton Mayoral poll held on June 15, 2013.  Rajshahi City Corporation has 30 wards in which there are 30 elected ward councilors.  Basically, Rajshahi City Corporation is a formation under the local government administration of Bangladesh to regulate the city area of Rajshahi, which is under the Ministry of Local Government & Rural Development (LGRD).  Currently the minister of LGRD ministry is Sayed Ashraful Islam.  Generally under local government, an election is held to elect a mayor of Rajshahi City Corporation.  This election is held in every 5 years.

Cahit Arf: Cahit Arf (] ; 11 October 1910 – 26 December 1997) was a Turkish mathematician.  He is known for the Arf invariant of a quadratic form in characteristic 2 (applied in knot theory and surgery theory) in topology, the Hasse–Arf theorem in ramification theory, Arf semigroups, and Arf rings.

Death and adjustment hypotheses: Death and adjustment hypotheses (DAH) is a theory about death and dying that focuses on death anxiety (psychology) and adjustment to death.  It was presented by Mohammad Samir Hossain as an answer to the overwhelming anxiety and grief about death.  In an attempt to find the resolution to death anxiety, predominantly the existential one, DAH postulates two key themes.  Its first part postulates that death should not be considered the end of existence and the second part emphasizes that the belief in immortal pattern of human existence can only be adopted in a morally rich life with the attitude towards morality and materialism balanced mutually.

Mohammad Samir Hossain: Mohammad Samir Hossain (born 28 November 1976) is a Bangladeshi theorist and one of the few Muslim scientists in the field of Death anxiety (psychology) research.  He is the pioneering physician to introduce Scientific Thanatology and Spiritual Psychiatry in Bangladesh.  He is also an author of multiple theory books on Death adjustment.
