to study the effect of different weed control methods in tomato, an experiment was conducted as completely randomized block design with three replications at the research farm of university of tehran (karaj) in 2008. the treatments consisted of post emergence (at recommended rate) or pre emergence (reduced rate in combination with mulch) application of metribuzin, rimsulfuron and sulfosulfuron,...

We report on the high-pressure growth, structural characterization, and investigation of electronic properties single-crystalline LaFeAsO co-substituted by Sm P, in both its normal- superconducting states. Here, appearance superconductivity is attributed to inner chemical pressure induced smaller-size isovalent substituents. X-ray refinements show that partial substitution La As P parent compou...

Quantitative information about the response of seedling emergence totemperature for safflower (Carthamus tinctorius L.) is rare. The main objective ofthe present study was to develop a model for predicting days to emergence forsafflower as influenced by the temperature. In this regard, a field experiment with arange of sowing dates and four safflower cultivars were conducted to describe theresp...

Introduction: Response to tracheal tube during emergence of general anesthesia is a main concern. We aimed to compare the effect of Remifentanil and Lidocaine on response to tracheal tube during emergence of general anesthesia. Materials and Methods: In this randomized clinical trial, we enrolled 80 consecutive patients with American Society of Anesthesiology (ASA) physical status I–II, who und...
