The Exponential Diophantine Equation 2x + by = cz

Let b and c be fixed coprime odd positive integers with min{b, c} > 1. In this paper, a classification of all positive integer solutions (x, y, z) of the equation 2 (x) + b (y) = c (z) is given. Further, by an elementary approach, we prove that if c = b + 2, then the equation has only the positive integer solution (x, y, z) = (1,1, 1), except for (b, x, y, z) = (89,13,1, 2) and (2 (r) - 1, r + ...

I-6: Azoospermia Factor in Male Infertility

Background The human Y chromosome is essential for human sex determination and male germ cell development and maintenance. In 1996, Vogt et al. identified three recurrently deleted regions in Yq11 termed the azoospermia factor (AZF). The AZF region is subdivided into three non-overlapping sub-regions called AZFa, AZFb and AZFc and microdeletion in these regions is the most important etiology of...

I-6: Remodelling Uterine Spiral Arteries inPregnancy

Background: During the first trimester of pregnancy the uterine spiral arteries that supply blood to the placenta are remodelled, creating heavily dilated conduits lacking maternal vasomotor control. To effect permanent vasodilatation, the internal elastic lamina and medial elastic fibres must be degraded. Failure of remodelling is a key characteristic of the pathological placenta and is though...

Pt/cz Comprehensive European Migration Policy

Afterwards, the Hague Program also endorsed the idea of a common European migration policy based on the study of migratory phenomena, acknowledging the relevance of legal migration, integration of third country nationals, migratory flows management, inclusion of biometrical data and visa policies, the fight against illegal immigration, return and readmission policies and partnerships with third...
