Let X be an algebraic variety over the algebraically closed field K and Ξ ⊆ X(K) a set of K-rational points on X. We say that a subvariety Y ⊆ Xn of some Cartesian power of X is Ξ-special if Ξn ∩ Y (K) is Zariski dense in Y . We show under certain hypotheses on Ξ, for instance, that the class of Ξ-special varieties is closed under intersections, that when subvarieties of X vary in an algebraic ...

UNLABELLED The present study was based on the impact of the superdisintegrants incorporation mechanism on the immediate realese of the tablets final performances. The aim was the selection of the working method to obtain Ranitidine 150 mg tablets with the desiderate quality and in reproducible conditions. MATERIAL AND METHODS The effect of the incorporation mode of sodium starch glycolate on ...

When considering single-dose preparations, it is fundamental that the patient receives in his individual dose an amount of drug close to that claimed on the label. Since drug content and content uniformity of single-dose preparations depend on a number of processes associated with their manufacture, it is obviously unrealistic to expect every unit of product to possess exactly the same amount o...

Introduction: Non-uniformity test is essentially the only required daily QC procedure in nuclear medicine practice. Noise creates statistical variation or random error in a flood image. Non-uniformity on the other hand does not have statistical nature and may be regarded as systemic error. The present methods of non-uniformity calculation do not distinguish between these two types of erro...

I ncreasing production efficiency is becoming a major theme for producers in order to maintain or increase their economic return in an increasingly competitive global market. In the case of irrigated agriculture, producers must also address increasing public concern about water conservation, water quality, and environmental protection. Two irrigation management issues require attention in order...

PURPOSE Published clinical trials support the use of 0.2 to 0.4 percent nitroglycerin ointment for the treatment of an anal fissure, although no product is yet available in the United States. In 2004, 84,000 prescriptions were written for compounded nitroglycerin ointment. This study was designed to evaluate the quality of extemporaneously compounded nitroglycerin ointment. METHODS Prescripti...

We investigate computing models that are presented as families of finite computing devices with a uniformity condition on the entire family. Examples of such models include Boolean circuits, membrane systems, DNA computers, chemical reaction networks and tile assembly systems, and there are many others. However, in such models there are actually two distinct kinds of uniformity condition. The f...
