Alfvén waves dissipation is an extensively studied mechanism for the coronal heating problem. These waves can be generated by magnetic reconnection and propagated along the reconnected field lines. Here, we study the generation of Alfvén waves at the presence of both steady flow and sheared magnetic field in the longitudinally density stratified of solar spicules. The initial flow is assumed to...

introduction: iran's social security organization provides hospital services through direct treatment system (hospitals owned by the organization) and indirect treatment system (purchasing of hospital services and other health care services from other providers). the current research aims to assess technical performance and determine the relationship between activity size and efficiency level o...

Asurvey study was conducted to assess the knowledge/awareness level in IPM technology among farmers. Four villages were randomly selected from Sargodha district for data collection. Thirteen farmers from each village were selected randomly and sample size was 52 respondents. More than 92% of respondents have no advisory services either from public or private sector. The findings imply that resp...

In this work, performance data from a small-scale reverse osmosis (RO) plant based on seawater FilmTec spiral wound RO membranes for different periods of operation are presented and analyzed. A prototype RO set-up with a 2,200 L/d capacity was installed and operated at Urla Bay which was located in Izmir, Turkey. This study typically investigates RO performance in terms ...

The study examined the factors influencing farm record keeping among small scale poultry farmers in zone A axis of the Kogi ADP comprising of -Yagba- East, Yagba-West, Kabba-Bunnu, Ijumu, and Mopamuro Local Government Areas. Using a three stage random sampling technique, 120 poultry farmers spread across the 5 LGAs within the zone A of Kogi ADP in Kogi State were randomly selected. With the aid...

In this paper the rapidly varied unsteady flow caused by the failure of a dam in a rectangular dry bed horizontal channel has been studied both theoretically and experimentally. Experiments with dam-break flows in smooth and rough channel have been carried out. Comparisons have been made between measured depth hydrographs at different stations along the channel and analytical solution of Ritter...

In this study, the techno-economic analysis of lignocellulosic biomass conversion to electricity in a small scale power plant was conducted. The proposed process is based on the thermal pathway of electricity production from a carbon content feed. Woods, forest and agricultural residues were considered as the biomass feed, which are available extensively in Iran. Besides, the process benefits n...

Brasica napus L. is one of the most important crops in the world, but every year during mechanized harvesting with conventional combines large quantities of the seeds fall to the ground and thus result in a decrease in yield. Therefore, designing and manufacturing a head specific for harvesting this crop is a high priority. In this study, the head of a combine for harvesting fine-grained produc...

the aim of the paper is to survey factors productivity in small & medium scale manufactories located in toos industrial town. in order to achieve this purpose, production functions of different industrial groups are estimated on the base of cross-section data in 2005. then elasticity of factors production, average productivity, marginal productivity, labor intensive and capital intensive are de...
