external fluted feed rolls are commonly used in grain drills. the fluted feed roll meters a volume of seeds and does not singulate the seeds as do the precision planters; therefore, there will be inherent variation in the number of seeds delivered per unit of time. this research was conducted to investigate the effect of seed meter drive shaft and ground speeds and outlet positions in a grain d...

Brassica chinensis varieties are mostly consumed as vegetables. In order to assess utility of microsatellite markers for testing distinctness, uniformity and stability of B. chinensis varieties, we used nine polymorphic microsatellite marker loci (with a total of 131 alleles) to evaluate four open pollinated and four hybrid varieties of B. chinensis. Each variety was represented by 48 randomly ...

OBJECTIVE To split several tablet products relevant to the Veterans Affairs (VA) Maryland Healthcare System and assess whether the resulting half tablets provide equal doses. METHODS From a VA list of products that are required to be split, 7 products were evaluated, along with 5 other commonly split tablet products. A trained pharmacy student split tablets using a tablet splitter provided by...

The Comparison analysis of the Wald’s and Bayestype sequential methods for testing hypotheses is offered. The merits of the new sequential test are: universality which consists in optimality (with given criteria) and uniformity of decision-making regions for any number of hypotheses; simplicity, convenience and uniformity of the algorithms of their realization; reliability of the obtained resul...

Relative-rate tests have previously been developed to compare the substitution rates of two sequences or two groups of sequences. These tests usually assume that the process of nucleotide substitution is stationary and the same for all lineages, i.e., uniform. In this study, we conducted simulations to assess the performance of the relative-rate tests when the molecular-clock (MC) hypothesis is...

In view of the uneven artificial sowing, low sowing, as well as the fact that the existing seeders cannot meet the sowing requirements of Pteris vittata, this paper designed an automatic plug seeder by using the method of spraying and sowing after mixing spores and water. In order to obtain the optimum working parameters of the seeder, response surface method (RSM) was employed to desi...

Pour des données axiales, le test d’uniformité plus classique sur la sphère unité de Rp est Bingham (Ann. Statist. 2 (1974) 1201–1225). Dans cet article, nous étudions puissance ce dans scénarios asymptotiques grande dimension pour lesquels p=pn diverge vers l’infini avec taille d’échantillon n. Nous considérons une classe semiparamétrique contre-hypothèses incluant les distributions Watson et ...

We test the hypothesis that the temperature of the cosmicmicrowave background is consistent with a Gaussian random field defined on the celestial sphere, using the full sky debiased internal linear combination (DILC) map produced from the three-yearWMAP data. We test the phases for spherical harmonic modes with ‘ 10 (which should be the cleanest) for uniformity, randomness, and correlation with...

A simple, rapid, precise and economical high performance thin layer chromatographic method has been developed and validated for determination of rosiglitazone in its tablet dosage form using caffeine as an internal standard. It was performed on silica gel 60 GF(254) thin layer chromatographic plates as a stationary phase using mobile phase methanol:toluene:chloroform:triethylamine (1:8:0.5:0.5 ...
