In order to investigate the effect of different nutrient solutions on yield and potato minituber production under aeroponic and hydroponic culture, a split-plot experiment based on completely randomized design with three replications was carried out in 2015. The main factor was culture medium (aeroponic and hydroponic) and the sub-factors consisted of nutrient solution (control, Etazu, Etazu+ h...

Certain microorganisms in soil have phosphate solubilizing ability. Phosphorus has an important role in plant nutrition and N2 fixation in legumes. The interactive effect of three phosphate solubilizing bacteria (PSB) and Bradyrhizobium japonicum on yield and N, P, K uptake and nodulation of soybean root (Glycin max L. CV. Harcor) was studied under greenhouse conditions. In greenhouse experimen...

the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...

one of the most important number sequences in mathematics is fibonacci sequence. fibonacci sequence except for mathematics is applied to other branches of science such as physics and arts. in fact, between anesthetics and this sequence there exists a wonderful relation. fibonacci sequence has an importance characteristic which is the golden number. in this thesis, the golden number is observed ...

according to coates’s (2004, as cited in zhang, 2010) definition of "conversational dominance" (p.111), it refers to the phenomenon of a speaker dominating others in interaction. specifically, it means how a speaker makes use of certain strategies to get the floor and maintain the floor. thus, the amount of talk is the main measurement for the dominance of the conversation. whether a speaker do...
