A pot experiment was conducted in a completely randomized design with five treatment and five replication, in each replication were 6 plants used. The study of zinc sulphate (ZnSO4) application (20 and 40 ppm) and Salicylic acid (SA) application (50 and 150 ppm) was compared to the control (distillated water) on growth and flowering Petunia hybrid. For each plant was used 10...

most theories in social sciences have aspects of causality, but understanding the causes of social phenomena is not possible through statistical correlation tests. to overcome this problem, fuzzy qualitative comparative analysis was developed to identify the cause of social phenomena. having qualitative roots, this method tests the necessary and sufficient causes for the emergence of a social p...

Objective. The etiology of active parenting remains almost entirely unexplored in political socialization. Applying ecological and dialectic perspectives, we propose a model of developmental provocation to capture contributions of youth to a politicization of parenting during campaigns. Methods. Parent-youth dyads in Arizona, Colorado, and Florida were interviewed across two election cycles. Ad...

The present study was investigated the effects of two elicitors methyl jasmonate (0, 125, 250 and 500 µM) and chitosan (0, 50, 150 and 250 mg L-1) on shoot and callus growth of Iranian Hypericum perforatumL. in vitro cultures in separate experiments. The experiment was done in the base of completely randomized design with five replications and five explants in each replication. Methyl jasmonate...

It is a piece of idle senthentality that truth, merely as truth, has any inherent power denied to error, or prevailing against the dungeon and the stake. Men are not more zealous for truth than they often are for error, and a sufficient application oflegal or even of social penalties will generally succeed in stopping the propagation of either. The real advantage which truth has, consists in th...

In Escherichia coli, an increase in the ATP bound form of the DnaA initiator protein results in hyperinitiation and inviability. Here, we show that such replication stress is tolerated during anaerobic growth. In hyperinitiating cells, a shift from anaerobic to aerobic growth resulted in appearance of fragmented chromosomes and a decrease in terminus concentration, leading to a dramatic increas...

this study was carried out to evaluate the effect of onion extract on growth performance, carcass characteristics and some blood metabolites in ross and cobb broiler chickens. one hundred sixty, 1-d-old broiler chickens (mean initial weight: 36.5 ± 1 g) of male sex (ross-308 and cobb) were randomly conducted as randomized complete design with 4 treatment and 4 replication. the experimental grou...

The accessory protein, Vpr, is a virion-associated protein that is required for HIV-1 replication in macrophages and regulates viral gene expression in T cells. Vpr causes arrest of cell cycle progression at G2/M, presumably through its effect on cyclin B1.Cdc2 activity. Here, we show that the ability of Vpr to activate HIV transcription correlates with its ability to induce G2/M growth arrest,...

A model which explains national-level house price appreciation through utility maximization by rational voters is developed and tested using a global sample of 40 democracies, in order to explain why some countries experienced house price bubbles in the past decade and others did not. In the model, a subsidy funded by a tax on all citizens can be provided to home buyers. The subsidy leads to an...
