Let k be a global field of positive characteristic, and let σ : X −→ Spec k be a smooth projective curve. We study the zero-dimensional cycle group V (X) = Ker(σ∗ : SK1(X) → K1(k)) and the one-dimensional cycle group W (X) = coker(σ∗ : K2(k) → H0 Zar(X,K2)), addressing the conjecture that V (X) is torsion and W (X) is finitely generated. The main idea is to use Abhyankar’s Theorem on resolution...

Zearalenone [6-(10-hydroxy-6-oxo-trans-1-undecenyl)-ß-resorcyclic acid lactone] is a mycotoxin produced as a secondary metabolite of various Fusarium fungi (see Figure 1). ZON is also known as RAL, F-2 toxin or ZAR. Zearalenone (ZON) has been detected in a variety of cereal products such as wheat, maize, barley, oats, rice and sorghum as well as beer that has been produced with contaminated gra...

ÖZET Sessiz otitis medya, ilerleyici otojenik bir hastalıktır. Bu subklinik enfeksiyöz hastalık timpanik zar normal olmasına rağmen mastoid kemik hücrelerini ve mukozalarını etkiler. Antibiyotik sonrası dönemde klasik mastoidit sıklığında ciddi bir düşüş mevcut olmakla birlikte, otitis medya için yetersiz veya etkisiz antibiyotik kullanımına bağlı gelişen sessiz mastoidit halen hayatı tehdit ed...

UNLABELLED BACKGROUND Although access to life-saving treatment for patients infected with HIV in South Africa has improved substantially since 2004, treating all eligible patients (universal access) remains elusive. As the prices of antiretroviral drugs have dropped over the past years, availability of human resources may now be the most important barrier to achieving universal access to HIV...
