Note on preserving a standard suspension of live vibrios.
It is difficult to prevent changes in biological characters of vibrio strains during storage (Martin, 1964). Even freeze-drying may be unsatisfactory for two reasons. First, only about 5% of viable cells survive the process (Fry and Greaves, 1951) allowing chance for selection of variants. Secondly, the viable cell count of each suspension made from regenerated cultures has to be ascertained. T...
متن کاملthe effects of cognitive strategies- note making and underlining- on iranian efl learners’ reading comprehension
هدف از انجام این مطالعه ، بررسی اثرات استفاده از استراتژی های شناختی یعنی "نت برداری" و "زیر خط کردن" بر روی عملکرد درک مطلب زبان آموزان ایرانی می باشد. به این منظور، 60 زبان آموز دختر سال چهارم دبیرستان از طریق آزمون پیشرفت زبان انگلیسی (نلسون)، از یک جامعه آماری بزرگتر انتخاب شدند. سپس به صورت تصادفی به سه گروه که هر گروه شامل ?0 دانش آموز همسان بود، تقسیم شدند: دو گروه آزمایش(گروه "نت برداری...
15 صفحه اولOn Equivariant Algebraic Suspension
Equivariant versions of the Suspension Theorem L 1 ] for algebraic cycles on projective varieties are proved. Let G be a nite group, V a projective G-module, and X P C (V) an invariant subvariety. Consider the algebraic join = V 0 X = X#P C (V 0) of X with the regular representation V 0 = C G of G. The main result asserts that algebraic suspension induces a G-homotopy equivalence Z s (X) ?! Z s...

متن کاملA study on Isatis suspension trap efficiency; Advantages and disadvantages
Different types of sediment trap have been introduced so far to be used in erosion measuring stations, each with its own advantages and disadvantages in trapping aeolian particles. These traps have different collection and retention efficiency due to aerodynamic conditions. Some characteristics such as isokinetic feature of the trap, collection efficiency, time needed to download sediment, capa...
