the application of a comprehensive model of communicative language ability (cla) to language teaching and testing has always been an imperative in l2 education since hymess proposal of communicative competence in the 1970s. recent l2 research has clearly underscored the importance of sufficient pragmatics representation as an essential component of cla in pedagogical and testing practices in l2...
this exploratory study aimed to investigate a possible relationship between learners’ beliefs about language learning and one of their personality traits; that is,locus of control (loc). both variables, beliefs and locus of control, are assumed to influence the language learning process. the internal control index (ici) and the beliefs about language learning inventory (balli) were administered...
the current thesis is composed in five chapters in the following fashion: chapter two encompasses the applied framework of the project in details; the methodology of carl gustav jung to explain the process of individuation, the major archetypes and their attributes and his techniques to assess the mind’s strata are all explained. moreover, the austrian psychoanalysts, heinz kohut’s models of a...
In arid areas, the rapid evaporation of water leads to severe shortage for plant growth. Superabsorbent polymers have prospect preventing because its excellent absorbency. However, insufficient in salt resistance, retention, and swelling rate limit application. Herein, we fabricated Hydroxyethyl cellulose-g-(Acrylic acid-co-2-Acrylamido-2-methyl-1-propane sulfonic acid)/laterite (HEC-g-P (AA-co...
Water scarcity is an important obstacle to the development and expansion of urban landscape in the arid and semi-arid regions of the world. Nowadays organic and artificial materials can be used to reducing water consumption without reducing the quality and quantity of urban landscape. In order to study of the effect of some mulch type on the reduce of irrigation interval on a popular seasonal p...

A simple two-steps polymerization method was used to prepare a polyacrylamide hydrogel with a full interpenetrating network structure based on the sorption and porous properties of polyacrylamide superabsorbent. In conditions of 10 g acrylamide monomer, 0.04 g crosslinker for the first polymerization and the second polymerization, respectively, and the swelling ratio of 9, the hydrogel possesse...
Drought conditions after sowing threaten the seedling establishment of all seeds, including cover crops. Cover crops are commonly broadcast and, thus, often susceptible to drought stress sowing. Our hypothesis was that seed coating with superabsorbent polymers (SAPs) would enhance germination in lab and stand field by increasing water availability single seeds. Red clover (Trifolium pratense L....
