Wettability is a major factor in determining whether a material can be effectively and efficiently used as a component in greenhouse substrates. Poor wettability can lead to poor plant growth and development as well as water use inefficiency. This research was designed to test the wettability and hydration efficiency of both traditional and alternative components of substrates under different i...

water scarcity is a major factor for limiting crop growth and development in arid and semi-arid regions. in order to study the effects of varying timing and severity of water deficit on mung bean phenological traits, a field experiment was carried out during 2009 growing season at agricultural research institute of zabol university. the experiment was laid out in split plot by using a randomize...

in order to investigate the effect of seed rate on seed yield and yield components of three rapeseed varieties, a split- plot experiment was conducted in randomized complete block design with four replicates during 2008-2009 at baykola agricultural research station, neka, mazandaran province. in this experiment four seed rates (5, 7, 9 and 11 kg.ha-1) as main plots, three rapeseed cultivars (hy...

We propose and analyze an efficient way to enhance four-wave mixing (FWM) signals in a four-subband semiconductor quantum well via Fano-type interference. By using Schrödinger-Maxwell formalism, we derive explicitly analytical expressions for the input probe pulse and the generated FWM field in linear regime under the steady-state condition. With the aid of interference between two excited subb...

AIM To compare the effect of four different finishing systems and diamond paste on ceramic roughness with the objectives of evaluating the roughness of ceramic surface of prepared specimens after abrasion, finishing and polishing. MATERIALS & METHODS A total of 50 test specimens were fabricated in the form of discs of diameter 13mm and 0.6mm thickness. Test specimens were then randomly distri...

OBJECTIVES To evaluate the degree of cure (%DC) of four self-etching, self-adhesive resin cements, and one conventional resin cement, in their self- and dual-curing mode. METHODS The self-etching, self-adhesive resin cements studied were RelyX Unicem (3M ESPE AG), Maxcem (Kerr Corporation), Biscem (Bisco, Inc.) and Multilink Sprint (Ivoclar Vivadent AG) and the classic resin cement was Multil...
