A dynamic cutting force and vibration model of the microendmilling process that accounts for the dynamics of the microendmill, influences of the stable built-up-edge, and the effects of minimum chip thickness, elastic recovery, and the elastic-plastic nature in ploughing/rubbing has been developed. Experimental validation has been performed, and the model is shown to predict the cutting force a...
this study investigated (a) the learners’ existing reading strategy repertoire, (b) the effect of instruction in reading strategies on learners’ strategic performance, and (c) the effect of explicit instruction in top-down reading strategies on reading comprehension ability of intermediate learners. the study was conducted with 40 intermediate efl learners in two groups of experimental and cont...
Chlorophyll-a indicates the biomass of phytoplankton as the primary production. Chlorophyll-a changes indicate the situation of the ecosystem. The present study was conducted for monitoring it in the northern part of the Persian Gulf and Oman Gulf. For this purpose, CTD and NASA site information was used. Samplings were done from January-March 2018-2021. Mean southern waters chlorophyll-a in ...
abstract the following study, in the first place, attempted to examine the effect of less experienced teachers participation in experienced teachers classes on their own skills and teaching methodology, in the second place, attempted to find out the role of teachers training in students achievements. for this purpose, 21 efl teachers were selected according to available sampling in kish l...
Three separate aspects of cutting are investigated which complement other papers on the mechanics of separation processes presented at this interdisciplinary Theo Murphy meeting. They apply in all types of cutting whether blades are sharp or blunt, and whether the material being cut is 'hard, stiff and strong' or 'soft, compliant and weak'. The first topic discusses why it is easier to cut when...
The study of geotechnical index properties soils in Oworoshoki, Kosofe, Lagos State was conducted to characterize and classify the soil samples. Disturbed undisturbed were collected at different shallow depths (1m, 2m 3m) from area laboratory test conducted. includes natural moisture content, atterberg limits (liquid limit plastic limit), particle size distribution, specific gravity, unit weigh...
One of the disadvantages of conventional milling tools is to produce a large amount of heat in cutting zone and so making the tool warmer. As a result, the tool would be worn and its life time would be reduced. Therefore, in long time machining, it is essential to change inserts and tools, continiously. A milling tool with self rotary cutting inserts was designed and manufactured that enables i...
In this paper, we propose two iterative methods for finding a common solution of a finite family of equilibrium problems for pseudomonotone bifunctions. The first is a parallel hybrid extragradient-cutting algorithm which is extended from the previously known one for variational inequalities to equilibrium problems. The second is a new cyclic hybrid extragradient-cutting algorithm....
esl/efl books play a crucial role in shaping language learners worldview of gender roles in society. the present study investigated the status of sexism in two sets of efl textbooks, one developed by non-native iranian authors (ili series) and the other by native authors (top notch series). first, two books from each series was selected randomly. then, a quantitative analysis was carried out wi...
the present study was conducted with a view to know the productive and reproductive performance of jamunapari, black bengal and crossbred goats in chittagong district during the period of may to december 2012. the data on productive and reproductive traits were collected from 324 goats as a whole. in the present study, the birth weight of jamunapari goats was higher than other crosses. the adul...
