abstract the present thesis seeks to critically read george orwell’s nineteen eighty-four and animal farm in the light of louis althusser’s thought and theory. the present thesis proceeds to examine and demonstrate althusser’s major concepts including ideological state apparatuses (isas), repressive state apparatuses (rsas), the structure, the subject, and ideological interpellation which r...
abstract recent studies suggest that prelistening activities play an important role in the development of listening comprehension (e.g. long 1990;chiang and dunkel 1992; schmidt-rinehart 1994; jensen and hansen 1995; robinson et al., 1995; buck, 1995; foster and skehan,1996; teng 1996; robinson, 2001; chang and read 2006). in line with previous studies and to shed light on a new aspect of sche...
Cancer disease has been on the increase recently in both developed and developing countries of the world resulting in 40 million deaths annually. Ethno-medicinal survey of indigenous herbal plants used in traditional medicine in the treatment of cancers was conducted in major communities in Bali, Gashaka and Sarduana Local Government Areas Taraba State Nigeria. Traditional medicine practitioner...
Gibberellins (GAs) are phytohormones that regulate a wide range of developmental processes in plants. Levels of active GAs are regulated by biosynthetic and catabolic enzymes like the GA 2-oxidases (GA2oxs). In tomato (Solanum lycopersicum L.) C19 GA2oxs are encoded by a small multigenic family of five members with some degree of redundancy. In order to investigate their roles in tomato, the si...
triamidefon is a triazole derivative, which have both fungicidal and plant growth regulator (pgr) properties, and also protect plants from several types of abiotic stresses. the influential mechanism of triamidefon on plants is not much studied. in this study effect of this compound on the drought stressed in tomato plants was investigated. the plants were subjected to 5 day interval drought st...
Background: Alkaloids are a group of nitrogenous compounds with potential effects on the physiological behavior of human and animals. Some of these compounds are considered important drugs in modern medicine, such as atropine and morphine. Plants are considered the most important source of alkaloids. Therefore, investigating the presence of alkaloids in different plants is very important. Usual...
chromosome counting was performed in nine populations of achillea tenuifolia lam and eight populations of a. bieberestinii afan (asteraceae) collected from hamedan and kermanshah provinces in the west of iran. chromosome numbers in both species varied from 2n=2x=18 to 2n=4x=36. some populations of both species showed (2n=4x=36) chromosome number that is the first report as polyploidy levels. an...
Soil salinity and water deficit are major problems for development of agricultural production. In this study, effects of growth promoting microorganisms (inoculation with Piriformospora indica and two isolates of Streptomyces sp.) on the leaf yield and absorption rate of some elements in leaves and roots of stevia plant was investigated under salinity conditions for two consecutive years (2016-...
In contrast to a single copy of Exo70 in yeast and mammals, the Arabidopsis genome contains 23 paralogues of Exo70 (AtExo70). Using AtExo70E2 and its GFP fusion as probes, we recently identified a novel double-membrane organelle termed exocyst-positive organelle (EXPO) that mediates an unconventional protein secretion in plant cells. Here we further demonstrate that AtExo70E2 is essential for e...
Most rewardless orchids engage in generalized food-deception, exhibiting floral traits typical of rewarding species and exploiting the instinctive foraging of pollinators. Generalized food-deceptive (GFD) orchids compete poorly with rewarding species for pollinator services, which may be overcome by flowering early in the growing season when relatively more pollinators are naive and fewer compe...
