Recognizing Tenured 4-H Adult Volunteers

Adult Volunteers

Five volunteers received intramuscular injections of 7 mg (approximately 500 mg) of cephanone, a new cephalosporin for parenteral use per kg. Peak serum concentrations averaged 36 jig/ml, about four times as high as with the same doses of cephalothin, twice as high as with cephaloridine, and slightly lower than with cefazolin. With a constant intravenous infusion of 100 mg/h, a steady-state ser...

The Selection of Tenured Astronomers in France

The organization of the recruitment of tenured astronomers and astrophysicists in France is presented and compared with the setup in other countries. The ages for getting tenure have increased from 27-28 in 1980 to 31 today. Foreign scientists constitute at least 11% of the recruits and the delay in their hiring is quantified. The large reliance on national tenure committees is justified, while...

Recognizing Bipolarizable and P 4-Simplicial Graphs

Hoàng and Reed defined the classes of Raspail (also known as Bipolarizable) and P4-simplicial graphs, both of which are perfectly orderable, and proved that they admit polynomial-time recognition algorithms [16]. In this paper, we consider the recognition problem on these classes of graphs and present algorithms that solve it in O(nm) time, where n and m are the numbers of vertices and of edges...

القای آپوپتوز در سلول‌های K562 تحت تأثیر یکی از مشتقات خانواده 4- آریل – 4 H کرومن

لوسمی میلوئیدی مزمن (Chronic Myelogenous Leukemia: CML) یکی از انواع شایع لوسمی‌ها است. برای درمان این بیماری ترکیبات مختلفی تاکنون برای القای تمایز و آپوپتوز ارائه شده است. ولی به دلیل مقاومت دارویی سلول‌های سرطانی این ترکیبات موثر نبوده اند. یکی از ترکیباتی که خواص ضد سرطانی قوی از خود نشان می‌دهد خانواده کرومن‌ها می‌باشند. در این مطالعه تاثیر یکی از مشتقات خانواده کرومن‌ها، از نظر سیتوتوکسیس...
