In this research, the FSW Butt joint of commercial aluminum 1050 was investigated by using the 7075 aluminum alloy interlayer on the linear velocity of 30, 50 and 100 mm / min, and rotational speeds of 800 and 1200 rpm. A threaded cylindrical tool was used for joining of the 5 mm sheets. The OM, SEM, microhardness and tensile tests were done. The results shows that in sample with an interlayer ...
The soil coulterometer is an “on‐the‐go” electro‐mechanical system which collects impedance force data at multiple depths using an oscillating coulter. During the initial testing (summer 2006), only vertical soil impedance force data was collected using a pressure sensor. To improve the performance of the coulterometer, an extended octagonal ring transducer was integrated into the system to col...
the present study sought to investigate the impact of using mind-mapping technique instruction on female elementary efl learners reading comprehension; it also investigated their attitudes towards using mind-mapping technique as a tool to improve their reading comprehension. this study followed a quasi-experimental design with two intact groups as experimental, and control groups. the participa...
The Texas Parks and Wildlife Department’s strategic management plan for catfishes (Ictaluridae) called the development of alternative harvest regulations Blue Catfish Ictalurus furcatus Channel I. punctatus. Angler these species in most reservoirs has been regulated using a 305-mm minimum length limit (MLL) 25-fish aggregate daily bag (DBL) since 1995. Using existing creel data collected 2003–2...
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...

gross rainfall (gr) partitioning into throughfall (tf), stemflow (sf) and interception loss (i) was studied in a pure oriental beech (fagus orientalis lipsky) forest located in the central caspian region of northern iran. measurements were performed on a rainfall event basis in a 5625 m2 plot of the kheyrud forest research station of tehran university during 2008 and 2009 growing seasons. gr wa...
we estimated the rainfall interception loss (i), canopy storage capacity (s), the ratio of mean evaporation rate from the wet canopy () over the mean rainfall intensity () (mm h-1) (), and free throughfall coefficient (p) in a fraxinus rotundifolia mill. stand located in an afforested park land in a semiarid region of iran. for each storm event, i was calculated as the gross rainfall (gr) minus...
