one of the main factors affecting on the technical and economic performance of farms and livestock is the ability or capacity management. main goal of farm management is achieving specific performance, profitability and productivity; there for measurement management and performance in livestock farms are necessary. considering the necessity of increasing production and quality in the dairy indu...

This paper combines quasi-Z-source into a typical five-level inverter, which includes two dc voltage sources, two quasi-Z-sources and five switching devices. In this structure, the output voltage amplitude is not limited to dc voltage source and it can be increased by quasi-Z-source. Besides, due to nature of Z-source families, this new structure is reliable and higher efficiency. Also, in this...

In this issue of Neuron, Newman et al. (2017) image calcium events at single synapses of unanesthetized Drosophila larvae. Synaptic plasticity and homeostatic regulation of synapses is established to be input specific. Furthermore, plasticity forms involve selective recruitment of previously active or silent synapses.

OBJECTIVE To investigate the resource efficiency and environmental impacts of producing one kilogram of edible protein from two plant- and three animal-protein sources. DESIGN Primary source data were collected and applied to commodity production statistics to calculate the indices required to compare the environmental impact of producing 1 kg of edible protein from kidney beans, almonds, egg...

Lignans constitute a group of phytochemicals, which are produced by oxidative dimerization of two phenylpropanoid units. Furfuran type lignans such as secoisolariciresinol, matairesinol, lariciresinol or pinoresinol are widely distributed in edible plants, and most of those dietary lignans are metabolized by the gut microflora to enterolactone and enterodiol, also known as enterolignans, tradit...
