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...
generally, fruit trees should produce sufficient yield annually through their economic life. fruit trees usually produce flowers over their ability of productivity. if all of the flowers are converted to fruit, the tree will be weak and poor smaller fruit will be produced and it may cause alternate bearing. thus some flowers must be removed by hand, mechanically or chemically. in this study, th...
In wild-type (WT) Columbia and Landsberg erecta ecotypes of Arabidopsis thaliana (L.) Heynh., trichomes are present on the adaxial surfaces of all rosette leaves but are absent from the abaxial surfaces of the first-formed leaves. We have determined that both long-day (LD) photoperiod and gibberellin (GA) stimulate trichome formation. WT plants grown in LD conditions produce the first abaxial t...
the aim of this study is to examine the difference between the introverts and extroverts in preferred advice-giving style. furthermore, it explores the difference between l1 (persian) and l2 (english) regarding the giving of advice for the extroverts and introverts separately. it investigates whether an extrovert or introvert gives advice in the same manner in his l1 (persian) and l2 (english) ...
in chapter 1, charactrizations of fragmentability, which are obtained by namioka (37), ribarska (45) and kenderov-moors (32), are given. also the connection between fragmentability and its variants and other topics in banach spaces such as analytic space, the radone-nikodym property, differentiability of convex functions, kadec renorming are discussed. in chapter 2, we use game characterization...
tulip is one of the most important flowers to precocity. treatment of tulip bulbs with gibberellic acid reduces the forcing period in the greenhouse resulting energy saving and reduces the tulip’s physiological disorders. this study carried out about three tulip cultivars includes ‘lacourtine’, ‘yokohama’ and ‘red favourite’. the results showed that gibberellic acid reduced significantly stem l...
ParC proteins. The results show that the use of 20 mg/L of Phe-Arg-β-naphthylamide decreased the MIC of nalidixic acid (from two to five serial twofold dilution steps) in all isolates tested, even in those with the nalidixic acid-susceptible phenotype. This high reduction in the MIC values was observed independent of the number of amino acid changes in GyrA and ParC. This effect was especially ...
Background and purpose: The presence of methanol in different types of drinks has caused problems and concerns. Therefore, developing a simple qualitative method to detect methanol in these products seems necessary. Ïn this study, a new easy low-risk sensitive and accurate method based on chromotropic acid (ÇÂ) has been suggested for the qualitative detection of methanol in various types of dri...
Extended Abstract Introduction and Objective: In order to overcome the contamination problems, as well as the usual method of increasing potato through micro tuber, micropropagation has been considered through tissue culture. The aim of this study was to evaluate the callus induction and embryogenesis in potato cultivars using leaf explants. Material and Methods: For this purpose, micropropa...
