The working parameters of the pneumatic sprayer, such as sprayer's attitude, airflow, and spraying amount, have an impact on evenness seed distribution during process vegetation restoration degraded grasslands . This article focuses 4BQD-40C sprayer analyzes forward speed, airflow velocity at inlet, frequency swinging nozzle quality. conclusion shows that: 1) equation trajectory was obtained, l...
Abstrac£: The possibiiity of determination of 6-phosphogluconate dehydrogenase (PGD) types from bloodstains made on filter paper was examined by starch gel electrophoresis. Addition of NADP to the gel and cathodal buffers yielded a rather better visualization of isoenzyme bands. The time limits of determination o£ PGD types were: at 40C 6 weeks, at room temperature 4 weeks, at 370C }ess than l ...
abstract the main purpose of this study was to investigate whether there was any significant difference between the speaking achievement of learners who were trained by means of consciousness raising of sociolinguistic skills and that of learners who were trained without the above mentioned task. the participants of this study consist of 60 intermediate level students participating languag...
critical thinking ability has an important role in education. accordingly, scholars around the world are searching for new ways for teaching and improving students critical thinking ability. in line with the studies in efl contexts supporting the positive relationship between critical thinking and writing performances, this study investigated the differential effects of halverson’s critical thi...
A study was conducted at Chanchra, Sadar Upazila, Jashore, Bangladesh during Rabi seasons of 2019-20 and 2020-21 to evaluate pre-harvest treatments inorganic nutrient sources on yield shelf life broccoli through Randomized Complete Block Design (RCBD) with three replications six which were; T1= soil test based 50% NPK blanket dose, T2=soil 75% T3= 100% T4=soil 125% T5=local farmers practice (N1...
This study was conducted at the farmer’s field of Jashore Sadar Upazila, Bangladesh during Rabi seasons 2020-2021 to evaluate pre-harvest foliar application effects mineral nutrients on yield, quality and shelf life broccoli. The experiment designed in Randomized Complete Block Design (RCBD), including three replications seven treatments for which were: T1=control, [email protected]%, [email protected]%), T4=...
This quick calculation implies that the only way to achieve the rated maximum power dissipation is to have a “perfect heatsink” or an “infinite heatsink.” The thermal impedance used in the calculation is from the junction to case only and assumes zero impedance into the ambient. This is practically impossible to achieve. Further, the ambient was assumed to be 25C (room temperature) which may no...
this study attempted to explore if teaching english collocations through two different modes of awareness-raising and input flooding has any possible differential effect on immediate retention as well as retention in a delayed assessment. it also compared the possible differential effect of teaching english collocations implicitly and explicitly on actively using the items in writing. m...
The temperature reaches around -40C to -60C in hilly and mountainous areas during winters which may lead to many probable natural hazards. Defence personnel as well as civilians are unaware of these hazards. Amongst all the natural hazards, Snow Avalanche is one of the major hazards which has the probability of occurrence in the above listed temperature range. The aim of this paper is to bring ...
