There are several forest operations involved in Eucalyptus timber harvesting. This study was carried out during brush-cutting; tree felling, bucking, delimbing, piling and manual extraction operations, with the following objectives: a) analyzing, ergonomically, two systems of brush-cutting: one manual and the other semi-mechanized, using two different machines; b) ergonomically evaluating three...

Borage herbs, wild herbs and is one year with significant economic value are highly regarded local market Due to the high economic value of borage any study to improve the quality of harvest and increase product seems necessary, Two Rahim Abad (GILAN) district in the province Eshkourat the highest level of production as the location of choice, and studies of the factors in determining the best ...

The objective of this study was to determine, via simulation, the premium required for dairy farmers supplying milk with a high concentration of unsaturated fatty acids (UFA) to a dairy processor to equal the operating profit ($/ha) of average farms, under New Zealand conditions. Fifty average farms (AVE farms) and fifty farms that fed an oilseed supplement to dairy cows (UFA farms) were simula...

It is appreciated that the marked increase in the prevalence of asthma over the past few decades reflects changes in environmental exposures and living conditions associated with modern lifestyles.1 Of particular interest is the documentation of a protective effect of exposures associated with traditional farming, the influence of which has waned with increased urbanization and the advent of me...

Novel mechanized silica nanoparticles incorporating a peptide-based molecular shuttle as a photo-responsive interlocked gatekeeper of nanocontainers are described including the uptake and delivery studies of a model cargo.

The self-complexation of mono-benzimidazole functionalized β-cyclodextrins was investigated. The unique molecular structure employed as supramolecular nanovalves were installed on the external surface of mesoporous silica to assemble mechanized silica nanoparticles, which showed pH-triggered release property.

Computer algebra systems (CASs) and automated theorem provers (ATPs) exhibit complementary abilities. CASs focus on ee-ciently solving domain-speciic problems. ATPs are designed to allow for the formalization and solution of wide classes of problems within some logical framework. Integrating CASs and ATPs allows for the solution of problems of a higher complexity than those confronted by each c...
