this study purported to compare and contrast the use of self-mention and evidentials as two mtadiscourse features in opinion columns of persian and english newspapers. the theoretical basis of this study is the idea that metadiscourse features vary across cultural boundaries. for this purpose, 150 persian and 150 english opinion columns were collected based on three factors of topic, audience a...
A field experiment was conducted inside a temperature gradient tunnel (TGT) at the ICAR-Indian Agricultural Research Institute, New Delhi during rabi 2014-15 to quantify impacts of elevated on thermal requirement, growth and yield wheat crop. Wheat crop subjected five treatments, i.e. +0ºC (representing ambient condition), +0.9ºC, +2.5ºC, +2.8ºC +3.5ºC.Temperature elevation 3.5°C increased accu...
identification of morphological, phenological and yield characteristics of genotypes is important in order to collect necessary information for available varieties and as a result selection of one or more specific traits. in this study, 73 kabuli chickpea genotypes from pulses seed bank of research center for plant sciences, ferdowsi university of mashhad, were planted in irrigated conditions a...
conservation tillage, a fast growing practice in iran, is considered as a means to achieve sustainability in agricultural systems. this study was carried out to determine the effect of tillage systems (no-tillage, minimum tillage and conventional tillage ) on yield and yield components of three irrigated wheat varieties. the field experiment was conducted at the experimental station of the univ...
This research was conducted at Atatürk University Plant Production and Research Centre Directorate during the 2017-18 2018-19 cropping years, adaptation of a total 60 barley varieties (34 alternative 26 winter varieties) examined in Erzurum dry agricultural conditions. According to average vegetative period varied between 244.8-255.6 days, grain-filling 27.0-32.3 plant height 83.8-117.8 cm, num...
Background: This study was conducted during the 2020/2021 cropping season at Setif Agricultural Experimental Station, it aims to assess efficiency of using numerical image analysis (NIA) in selection durum wheat genotypes semi-arid areas. Methods: The genetic materials used this consist 11 advanced lines and 4 which 3 are local landraces as control evaluate their performance, tested were sown a...
we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...
Drought stress is the most important environmental stress that affects many morphological, physiological and, especially, yield traits of arable crops. In this research, a cross between the cultivar Gaspard (dehydrated susceptible parent) and DN11 line (drought resistant parent) was performed. F1, F2, F3, BC1 and BC2 generations along with parents, were planted and compared in a randomized...
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...
This study examines the rules governing the transfer of spikes between the retina and the lateral geniculate nucleus (LGN) with the goal of determining whether the most informative retinal spikes preferentially drive LGN responses and what role spike timing plays in the process. By recording from monosynaptically connected pairs of retinal ganglion cells and LGN neurons in vivo in the cat, we s...
