The blood and bone marrow constitute the hematologic organ system. Unlike other organ systems, hematologic organs are distributed in space and provide for a variety of seemingly unrelated functions. The hematologic system has both cellular and fluid-phase elements. Cellular elements include erythrocytes, leukocytes, and platelets; fluid phase elements include coagulation factors, natural antith...
Nowadays, organ transplant is an inevitable necessity for patients in need who other medical treatments don’t work for them. Nevertheless, it has become one of the major challenges of societies to find transplantable organs in order to bring patients in need back to society and their families. The statistics points out that in the year 2017, despite the issuance of the four million organ donati...
Background: Organ transplant is considered the treatment of choice for patients with end-stage organ disorders. This process improves recipient’s longevity and quality of life. However, organ shortage for transplantation has remained an unresolved global issue. One of the primary sources of organ donation is brain-dead bodies. The most important factor that impedes the success of donation is la...
Organ donation is one of the most remarkable and dramatic therapeutic advances in medicine during the past 60 years. Expansion of Organ donation has been compelled many countries to legislate about this subject. In our country, Iran, because our acts are based on Islamic jurisprudence it is necessary to study about organ donation in view of jurisprudence. For example the 32th verses of Maedeh S...
In his paper ”Finite groups have many conjugacy classes” (J. London Math. Soc (2) 46 (1992), 239-249), L. Pyber proved the to date best general lower bounds for the number of conjugacy classes of a finite group in terms of the order of the group. In this paper we strengthen the main results in Pyber’s paper.
The dynamic impedance of a sphere oscillating in an elastic medium is considered. Oestreicher's [J. Acoust. Soc. Am. 23, 707-714 (1951)] formula for the impedance of a sphere bonded to the surrounding medium can be expressed in a relatively simple form in terms of three lumped impedances associated with the displaced mass and the longitudinal and transverse waves. If the surface of the sphere s...

It is unclear whether the perceptual segregation of a mistuned harmonic from a periodic complex tone depends specifically on harmonic relations between the other components. A procedure used previously for harmonic complexes [W. M. Hartmann et al., J. Acoust. Soc. Am. 88, 1712-1724 (1990)] was adapted and extended to regular inharmonic complexes. On each trial, subjects heard a 12-component com...
It has been proposed that young children may have a perceptual preference for transitional cues [Nittrouer, S. (2002). J. Acoust. Soc. Am. 112, 711-719]. According to this proposal, this preference can manifest itself either as heavier weighting of transitional cues by children than by adults, or as heavier weighting of transitional cues than of other, more static, cues by children. This study ...
