In week ending 19 May, 4.9 million re...

The severe consequences and high mortality of COVID-19 prompted the development a wide range preventive vaccines. first vaccines to be tested were developed in China formulated as inactivated SARS-CoV-2 adsorbed on aluminium hydroxide. One quality indicators for is degree adsorption, which can used control content not only non-adsorbed antigen, but also specific antigen one dose vaccine. aim st...

the leishmania major parasite surface antigen-2 (psa-2) is a family of glycoinositol phospholipids anchored glycoprotoins expressed in both promastigotes and amastigotes. promastigote psa-2 comprises three polypeptides with approximate molecular weight of 96, 80 and 50 kda. amastigote express a distinct but closely psa-2 polypeptide with molecular weight of 50 kda. in this study fusion of sp2/0...

But these experiments [2] will not give us any information about the dependence or independence of the two factors, namely study habit and home environment. In such cases, we resort to Factorial ANOVA which not only helps us to study the effect of two or more factors but also gives information about their dependence or independence in the same experiment. There are many types of factorial desig...

In this paper, the Dai-Kou type conjugate gradient methods are developed to solve the optimality condition of an unconstrained optimization, they only utilize gradient information and have broader application scope. Under suitable conditions, the developed methods are globally convergent. Numerical tests and comparisons with the PRP+ conjugate gradient method only using gradient show that the m...

Analysis of variance (ANOVA) is a statistical method that is widely used in the psychosomatic literature to analyze the results of randomized trials, yet ANOVA does not provide an estimate for the difference between groups, the key variable of interest in a randomized trial. Although the use of ANOVA is frequently justified on the grounds that a trial incorporates more than two groups, the hypo...
