A water deficit during stage III of fruit growth was established with the aim of determining if it is possible to achieve an improvement in tree water status by summer pruning and fruit thinning. The experiment was set up as a randomized block split-plot design across trials (irrigation) where pruning was assigned to the main plot and fruit thinning to the sub-plots. The irrigation treatments w...

This paper presents how we improved the efficiency in rotary compressor. At first, we made effort to estimate the power losses in the compressor, to analyze the operating conditions of the bearing and to calculate the performance of the compressor. Next, the temperature in housing and pressure in cylinder were measured in real compressors in order to obtain the data on the internal conditions o...

Development of virgin and fallow lands in Kazakhstan has highlighted a number problems the economy republic. Introduction huge territories into land turnover extreme conditions required search creation irrigation system North-Kazakhstan region. Authors note that region, having difficult natural-climatic caused by sharply continental climate, there was deficit fresh artesian water. Therefore, on...

It is widely argued that farmers are unwilling to pay adequate fees for surface water irrigation to recover the costs associated with maintenance and improvement of delivery systems. In this paper, we use a discrete choice experiment to study farmer preferences for irrigation characteristics along two branch canals in Punjab Province in eastern Pakistan. We find that farmers are generally willi...

BACKGROUND The present study is designed to evaluate the clinical effects of pulsated subgingival irrigation with tetracycline and spiramycin. MATERIALS AND METHODS Ten patient diagnosed chronic periodontitis were included in the present study. Each patient is assigned to be irrigated with saline (placebo) (Group A), tetracycline HCl at 0.5% concentration (Group B), and 0.5% spiramycin (Group...
