Methods: Socio-demographic and clinical data of 484 patients with GI cancer collected during the years 1990-1991were available from Babol Cancer Registry. Patients were followed up for 15 ye...

The aim of the article is to examine the Academic Model United Nations (Model UN) as a context-based integrative educational technique in profession-oriented foreign language teaching (FLT); to point out the context-based integrative nature of profession-oriented language learning and highlight the importance of using product-based educational techniques in FLT for developing students’ future p...

habrobracon hebetor say (hymenoptera: braconidae) as an ectoparasitoid of larval stage of lepidopterous pests is widely used in biological control programs. in the present research, the effect of field recommended doses of imidacloprid, indoxacarb and deltamethrin were studied on life table parameters of h. hebetor in pupal stage treatment. one hundred, two-day-old pupae were treated with 1 mic...

demographic parameters of the pink stem borer, sesamia creticalederer (lepidoptera: noctuidae) were estimatedon its two main host plants, maize and sugarcane. the present studywas conducted under laboratory conditions at 27±1˚c, 50±10% relative humidity (rh %), and a photoperiod of 0:24 (l:d) hour for the larval stage and 16:8 (l:d) hour for the other life stages. the raw data were analyzed bas...

to provide reliable information concerning reproductive potential of hippodamia variegata goeze and its prey (aphis fabae), their related life tables were studied under controlled laboratory conditions (at 23?c). the unprocessed data of life tables were analyzed taking the euler-lotka as the basis model. standard error of population growth parameters was calculated using the jackknife re-sampli...

reproductive performance and life expectancy of the two-spotted spider mite (tssm), tetranychus urticae koch were determined on seven eggplant cultivars (isfahan, dezful, shend-abad, neishabour, bandar-abbas, jahrom and borazjan) at 25 ± 1°c, 60 ± 5% r.h. and a photoperiod of 16:8 (l:d) hours. the results revealed that the tssm gross hatch rate varied from 59% on bandar-abbas to 83% on dezful. ...

We introduce an algorithm to determine when a sorting operation, such as stack-sort or bubble-sort, outputs a given pattern. The algorithm provides a new proof of the description of West-2-stack-sortable permutations, that is permutations that are completely sorted when passed twice through a stack, in terms of patterns. We also solve the long-standing problem of describing West-3-stack-sortabl...

Abstract In 2013, UN-HABITAT provided the City Prosperity Index (CPI) to evaluate policies and guide urban decision-makers. Quality of life is one of the five dimensions of urban prosperity, which is one of the newest theories in the field of urban planning. The concept of urban quality of life has been invigorated in the wake of social welfare and social justice schools. In Iran, from the past...
