this study investigated how group formation method, namely student-selected vs. teacher-assigned, influences the results of the community model of teaching creative writing; i.e., group dynamics and group outcome (the quality of performance). the study adopted an experimental comparison group and microgenetic research design to observe the change process over a relatively short period of time. ...
Sarta longhorned beetle, Aeolesthes sarta, is one of the most destructive wood borer pests of fruit and shade trees in Iran. In this research, the reproductive parameters were studied under laboratory conditions. Fifteen pairs of newly developed adults (1-2 days after emergence from overwintering sites) were caged separately on 15 logs of Ulmus carpinifolia and fertility table was made using th...
Investigations on the biology of Phlebotomus papatasi were carried out under laboratory conditions at 28 +/- 2 degrees C and 80 +/- 1% RH. Fecundity of the female varied between 61 and 48 (mean 56.2 +/- 5.46) and the incubation period of eggs ranged from 7-9 (mean 7.81 +/- 0.61) days. The developmental duration of larvae and pupae varied from 24 to 31 (mean 28.57 +/- 2.71) and 9 to 11 (mean 10....
the development, survival, and reproduction of diamondback moth (dbm), plutella xylostella (l.), were studied in laboratory at 25±1°c, 65±5% rh and a 14l: 10d hours photoperiodism on five host plants of: cauliflower (brassica oleracea l. var. botrytis), two varieties of cabbage (b. oleracea l. var. capitata) namely ‘globe master’ and ‘scarlet ohara’, kohlrabi (b. oleracea l. var. gongylodes), a...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
the prey suitability for generalist predators is an important feature for efficient mass rearing and ipm. the green lacewing, chrysoperla carnea (stephens) is a polyphagous predator attacking several pests on various crops. this experiment was conducted under laboratory conditions at 25 ± 2 °c, 60 ± 5% r. h. and a photoperiod of 16l: 8d h. the effects of different prey species were investigated...
nowadays, technical terminology translation plays an important role in human life. specific groups of people all over the world refer to learn these terminologies in order to be familiar with a subject and improve their knowledge in that domain. on the other hand, saving the technical translation equivalent is a particularly salient challenge for technical translators. the present study was con...
