a large number of single research studies on the effects of strategy-based instruction (sbi) in teaching english as a foreign or second language has been conducted so far. however, the lack of a comprehensive meta-analysis targeting the effectiveness of english language sbi is observed. moreover, the findings of experimental studies regarding the context of the english language, proficiency lev...
We studied the suitability of municipal solid waste compost (MSWC) application to submerged rice paddies in the perspective of metal pollution hazards associated with such materials. Experiments were conducted during the wet seasons of 1997, 1998 and 1999 on rice grown under submerged condition, at the Agriculture Experimental Farm, Calcutta University at Baruipur, West Bengal, India. The treat...
Let G be an edge-colored graph. A rainbow (heterochromatic, or multicolored) path of G is such a path in which no two edges have the same color. Let the color degree of a vertex v to be the number of different colors that are used on edges incident to v, and denote it by dc(v). In a previous paper, we showed that if dc(v) ≥ k (color degree condition) for every vertex v of G, then G has a rainbo...
Irrigation water deficit is an important factor that affect rice production in the world as well as Guilan province in Iran. Intermittent irrigation method can be applied to compensate for the water shortage in rice growing areas, however, it would affect other crop mangement practices such as fertilizer application and mangement. Therefore, this experiment was conducted to determine optimum fe...
Katoul is a new soybeam cultivar originated from a genotype named D.P.X.3589 imported from the United States of American in 1990. This genotype was examined together with other soybean genotypes and check cultivars in different preliminary and advanced yield traits in Gorgan and other research stations during 1999-2002. The mean seed yield of D.P.X.3589 in all these experiments was 3333 kgha-1 ...
The use of organic and biological fertilizers is important for achieving sustainable agriculture, reducing the application of chemical fertilizers and the production of healthy crops. A greenhouse experiment was carried out to study the effects of vermicompost, Nitragin, and nitrogen on some growth parameters of strawberry (Fragariaananassa Duch. cv. Aromas). Treatments were arranged in a facto...
line no. 4 was selected from local champ a rice of lord egan, based on pure line selection method, during 1992 to 1995. the mean yield of this line was 6342 and 6829 kgha-l in two regions of lord egan in 1996 to 1997. the yield of this line was 700-1500 kgha-l more than that of lord egan local rice. line 4 is more early maturing than the local rice with better marketability and quality. amylase...
In this paper, the performance of quadratic residue (QR) codes of lengths within 100 is given and analyzed when the hard decoding, soft decoding, and linear programming decoding algorithms are utilized. We develop a simple method to estimate the soft decoding performance, which avoids extensive simulations. Also, a simulation-based algorithm is proposed to obtain the maximum likelihood decoding...
