Plants are often subjected to periods of soil and atmospheric water deficit during their life cycle. The frequency of such phenomena is likely to increase in the future even outside today's arid/semi-arid regions. Plant responses to water scarcity are complex, involving deleterious and/or adaptive changes, and under field conditions these responses can be synergistically or antagonistically mod...

In learning and development, self-regulation can be described as the degree to which individuals are metacognitively, motivationally, and behaviourally proactive participants in their learning process (Zimmerman, 1989, 2006). We examined the relationship between self-regulation and performance level in elite (n=159) and nonelite (n=285) youth soccer players aged 11 to 17 years (mean age 14.5, s...

In the present study, several pre-polymerized coagulants of iron and aluminum were tested for their efficiency towards As(V) and As(III) removal from water sources. The results showed that the pre-polymerized coagulants of iron, such as poly-ferric sulfate and poly-ferric silicate chloride, were very efficient for As(V) removal. With regard to As(III) removal, among all examined coagulants, inc...

Public utility services matter. Around the world, access to clean water and sanitation facilities, effective telecommunications and Internet services and reliable energy and transport services are indispensible to individuals, societies and economies. Given their critical importance, the public utility industries have long been subject to government regulation. The pages that follow seek to des...

The oxidative cleavage of cis-epoxycarotenoids catalyzed by 9-cis-epoxycarotenoid dioxygenase (NCED) is considered to be the rate-limiting step in abscisic acid (ABA) biosynthesis. Here we demonstrate that the expression of AhNCED1 gene in peanut plants is significantly up-regulated by dehydration and high salinity. The AhNCED1 transcript and endogenous ABA both accumulate predominantly in leav...

Abstract Telescopic water intake structures play an important role in a management system. The article is devoted to the improvement of telescopic and development solution for regulating their operation. Different types intakes are analyzed, shortcomings identified. known reviewed, operating principles analyzed. It has been determined that design existing lacks device stopping operation water. ...
