in order to perform each component of agricultural practices, its plan should be rationalized economically and technically. in a study for recognition patterns of energy inputs and outputs in saffron fields of southern khorasan, iran, during a five years exploitation period, two questionnaires were prepared, one for the first cultivation year, and another for crop management and harvest during ...

the aim of this study was to determine changes in the concentration of leptin and thyroid hormone in energyrestricted ewes and effect of leptin injection on thyroid hormone level. in the first experiment, 28 ewes were assigned to two groups(n=14). ewes were fed by a ration that provided 60% or 100% of maintenance energy requirements during 71 days. blood samples were collected and body weight(b...

We describe the importance of having low-energy (10-100 MeV) neutrino beams produced through the decay of boosted radioactive ions (“beta-beams”). We focus on the interest for neutrino-nucleus interaction studies and their impact for astrophysics, nuclear and particle physics. In particular, we discuss the relation to neutrinoless double-beta decay. Finally, we mention the status as far as the ...

Manufacturers have seen huge changes in the last 20 to 30 years. There are few aspects of business that have not been affected by information and technology, and the dynamics of product development, deployment, and customer relations have been forever changed. Thirty years ago consumers did not have the option to choose from hundreds of manufacturers and suppliers via the Internet; they had a v...

This article describes the state of knowledge of weak interactions in 1960, the conception and implementation of the first high-energy neutrino experiment, and the not altogether unexpected result that the muon neutrino is different from the electron neutrino.

Spherical time projection chambers (TPC), also known as spherical proportional counters, are employed in the search for rare phenomena, such light Dark Matter candidates. The TPC exhibits a number of essential features, making it promising candidate neutrinoless double beta decay (??0?). A tonne-scale experiment could cover region parameter space relevant inverted mass hierarchy with few years ...
