While wind farms have no inherent storage to supply power in calm conditions, this paper demonstrates that large tidal turbine farms in channels have short-term energy storage. This storage lies in the inertia of the oscillating flow and can be used to exceed the previously published upper limit for power production by currents in a tidal channel, while simultaneously maintaining stronger curre...

this study was conducted to reveal the impact of rural-urban migration on broiler production in the niger delta region of nigeria. data were collected from 795 household heads and farmers/managers/supervisors of 25 selected broiler farms in the study area. descriptive statistics and multiple regression analysis was utilized to analyze the data. able bodied young men constituted most of the rura...

Mechanized reasoning uses computers to verify proofs and to help discover new theorems. Computer scientists have applied mechanized reasoning to economic problems but – to date – this work has not yet been properly presented in economics journals. We introduce mechanized reasoning to economists in three ways. First, we introduce mechanized reasoning in general, describing both the techniques an...

seed loss at harvesting time is one of the factors reducing seed yield in at farms. this study was carried out within a research farm in karaj to evaluate and select a proper pinto bean line for mechanized harvesting at two moisture contents during harvesting and their effect on seed yield and yield loss among three lines of pinto bean. the experiment was split-plot based on randomized complete...

Global support for Conservation Agriculture (CA) as a pathway to Sustainable Intensification is strong. CA revolves around three principles: no-till (or minimal soil disturbance), soil cover, and crop rotation. The benefits arising from the ease of crop management, energy/cost/time savings, and soil and water conservation led to widespread adoption of CA, particularly on large farms in the Amer...

In recent years there has been a substantial increase in cystic echinococcosis in Kazakhstan. There are several factors that have contributed to this change in the epidemiology of the disease. The primary reason was the degradation of traditional nomadic system of livestock breeding and closing of large collective farms. Small private farms have started to keep stock year round in closer proxim...

in recent years, the debate over the environmental sustainability of agricultural productions is widely increased. in this context, environmental impacts of potato production by semi-mechanized method were studied in markazi province of iran. in this research, life cycle assessment approach was used to identify and reduce environmental impacts. the environmental impacts of potato production in ...

This study was aimed at assessing how efficient the small scale fishing units in Lagos State, Nigeria use the monetary inputs: costs of gear repairs, craft repairs, fuel, fishing losses, hired labor, and the residual costs of craft and gear. Between January and December, 113 mechanized and 43 non-mechanized fishing units in 21 purposively chosen coastal villages were surveyed bi-monthly through...

A human operator assembles components using his skill and judgement which is difficult to incorporate in a mechanized device. Though the mechanized system will offer higher speed and reliability, but its inherent inaccuracies will limit the success in assembling. Thus, it is essential that these inaccuracies are determined to establish its ‘Process capability’ , and also provide information for...
