EXAMINATION OF NONSTERILE Preparation of Test Strains PRODUCTS: MICROBIAL Use standardized stable suspensions of test strains or prepare as stated below. Seed-lot culture maintenance techENUMERATION TESTS niques (seed-lot systems) are used so that the viable microorganisms used for inoculation are not more than five passages removed from the original master seed-lot. Grow each of the bacterial ...

Abstract. Let K be a field of characteristic 0 and let (K) denote the n-fold cartesian product of K∗, endowed with coordinatewise multiplication. Let Γ be a subgroup of (K) of finite rank. We consider equations (*) a1x1+ · · ·+anxn = 1 in x = (x1, . . . , xn) ∈ Γ, where a = (a1, . . . , an) ∈ (K). Two tuples a,b ∈ (K) are called Γ-equivalent if there is a u ∈ Γ such that b = u · a.

Statistical heterogeneity and small-study effects are 2 major issues affecting the validity of meta-analysis. In this article, we introduce the concept of a limit meta-analysis, which leads to shrunken, empirical Bayes estimates of study effects after allowing for small-study effects. This in turn leads to 3 model-based adjusted pooled treatment-effect estimators and associated confidence inter...

A stability-indicating micellar liquid chromatographic (MLC) method was developed and validated for the quantitative determination of timolol maleate (TM) in the presence of its degradation products resulting from accelerated degradation in a run time not more than 8 min. TM was subjected to stress conditions of hydrolysis (including alkaline, acidic and thermal hydrolysis) and oxidation. An is...

accurate estimation of reference evapotranspiration plays a key role in water resources management and irrigation scheduling. the fao penman-monteith (f-p-m) is a reference method for calculation of evapotranspiration that needs temperature, humidity, wind speed and solar radiation. in many stations, it is not an easy task to measure the whole weather variables. thus, in this situation, one mus...
