Small RNAs, such as microRNAs (miRNAs), regulate gene expression and play important roles in many plant processes. Although our knowledge of their biogenesis and mode of action has significantly progressed, we still have comparatively little information about their biological functions. In particular, knowledge about their spatio-temporal expression patterns rely on either indirect detection by...

ACGT cis-acting DNA sequence elements have been identified in a multitude of plant genes regulated by diverse environmental, physiological, and environmental cues. In vivo transient and transgenic plant expression studies have shown that these ACGT elements are necessary for maximal transcriptional activation. Plants possess a conserved family of DNA-binding proteins specific for these DNA sequ...

this study investigates the relationship between litter quality and aerial parts of plant on c, n, k, p and c/n ratio of soil in four rangeland species including agropyron intermedium, bromus tomentellus, eurotia ceratoides and kochia prostrata. after recognizing the sites of these species in hamand absard located in 65 km of northern tehran, at the end of growing season, samples of litter, aer...

The presented method allows achieving maximum overshoot and specified settling time of the closed-loop step response. It provides a simple way to control linear stable SISO systems even if the mathematical model is unknown. Tuning rule parameters are based on one suitably chosen point of the plant frequency response obtained by sine-wave signal with specified excitation frequency, and the requi...

high tibia osteotomy is a common procedure in orthopedic surgery. a precise overview on indications, patients selection, pre-operative planning, surgical technique, methods of fixation, and complications have been presented. this paper focused on the points that should be considered to achieve good long-term outcomes. high tibia osteotomy is a common procedure in orthopedic surgery. a precise o...

Plant diseases are considered one of the main factors influencing food production and minimize losses in production, it is essential that crop have fast detection recognition. The recent expansion deep learning methods has found its application plant disease detection, offering a robust tool with highly accurate results. In this context, work presents systematic review literature aims to identi...

The use of modeling and simulation has developed into a critical tool for the sustainable management wastewater, especially when it comes to replicating complex biochemical procedures required fertilizer effluent treatment, which calls significant amount wastewater-related data. biological improvement urea via GPS* was carried out in this work using methodical process. Using established analyti...

Two sample sets of low density polyethylene (LDPE) were investigated and differentiated via comprehensive analysis their microstructures with specific emphasis on branching.
