In the political arena, it is almost always advantageous to frame an issue in economic terms when seeking support from a legislative body. This paper describes, measures, and provides illustrative examples for estimating the economic value of 12 benefits associated with urban parks. Seven of these constitute a template for measuring the economic value of an urban parks system that has been deve...

Metal-enclosed switchgear, which are widely used in the distribution of electrical energy, play an important role in power distribution networks. Their safe operation is directly related to the reliability of power system as well as the power quality on the consumer side. Partial discharge detection is an effective way to identify potential faults and can be utilized for insulation diagnosis of...

abstract some issues such as dehydration, local and chronological disproportion of rainfall, low productivity of water in agricultural sector, increasing demand for agricultural products due to increase in population participate with doughtiness are the most challenges of agricultural water. these factors caused water to be as one of the important and scarce inputs is agricultural products. the...

given the strategic remarkable rank of pistachio in non-oil exports, inputs’ management in its production is so important. as the scarcest input in agricultural sector, water is considered to be among the most important inputs of pistachio production.water inadequate supply and limate conditions increase water demand in pistachio growing areas. it is necessary to determine the real value or pri...

We calculate the lowest order cross–section for Dirac magnetic monopole production from photon fusion (γγ) in pp̄ collisions at √ s = 1.96 TeV, pp collisions at √ s = 14 TeV, and we compare γγ with Drell–Yan (DY) production. We find the total γγ cross–section is comparable with DY at √ s = 1.96 TeV and dominates DY by a factor > ∼ 50 at √ s = 14 TeV. We conclude that both the γγ and DY processes...

BACKGROUND The assessment of the economic burden of surgical disease is integral to determining allocation of resources for health globally. We estimate the economic gain realised over an 11-year period resulting from a vertical surgical programme addressing cleft lip (CL) and cleft palate (CP). METHODS The database from a large non-governmental organisation (Smile Train) over an 11-year peri...

this study investigated the effects of land size and two leased and private farming systems of machinery on economic efficiency and factors such as total production cost per hectare (ratio of total cost of agricultural inputs and operations to farm size), total income (ratio of product and byproduct value to farm size), yield (ratio of crop production to farm size) and degree of mechanization f...

Stylet-Oil was effective in reducing incidence of tobacco etch virus (TEV) (Genus: Potyvirus, Family: Potyviridae) in ‘Scotch Bonnet’ pepper (Capsicum chinense Jacquin) plots by about 24% and delaying its spread by 7 days. A backpack mist blower (low volume) was used to apply JMS Stylet-Oil at pressures of about 1000 kPa to pepper plants weekly, from transplant until the end of the crop. Seedli...
