one method of seed placement into the soil as regards no-till system is the use of punch planting by which one can plant through a considerable depth of surface residue. the study was conducted using a 2?3 split-plot experimental design of three replications. the factors considered were two types of plantes (conventional planter vs. hinging pneumatic punch planter) and three levels of wheat res...

Comparison of two numbers in RNS systems is a challenging task. In this paper, a new algorithm to compare the magnitude of two RNS numbers, using a clustering method has been proposed. In the clustering process, each inputted number is assigned to a cluster. To compare the magnitude of two numbers, first the clusters of these numbers and their differences are obtained. Then by comparing these c...

satellite imagery was used as a rapid and spatially explicit method to delineate crop residue cover and to estimate the use and intensity of conservation tillage. the potential of multispectral high-spatial resolution of worldview-2 local data was evaluated using 11 satellite spectral indices and linear spectral unmixing analysis (lsua). experimental plots were examined; residue cover was measu...

background: pistachio is one of the main nutrients, not only as a strategic crop but also as a main type of nut, in iranians’ food cycle. the aim of this study was to measure the relative safety of iranian pistachio based on the standard pesticide’s residue limits, which should be monitored and assessed in the cultivation of pistachio in order to confirm its public health. methods: fifty sample...

honey is the oldest natural food produced by honeybee and comprises wide variety of valuable ingredients including carbohydrate, proteins, minerals, vitamins, organic acids, polyphenols and flavonoids that contribute to well-known therapeutic properties. this review provide available scientific information on different ways of honey adulteration and chemical contamination with the certain focus...

objective: the usage of pesticides has increased during the recent years. one the other hand, presence of harmful pesticides residue in rice and other food has caused a great concern among the consumers. therefore, it is important to develop some pragmatic procedures to increase the food safety along with the reduction in consumption of pesticide residues. methods: a gas chromatograph with elec...
