this experiment was conducted for three consecutive years from 2000 to 2002 to evaluate the effects of integrated weed management on weeds of alfalfa at the safi abad agricultural research farm of dezful. the experimental design was a randomized complete block with strip-split plot arrangement of treatments. herbicide treatment was as horizontal factor at five levels which in 2000, consisted of...
This study evaluated the surface of different types of fiber posts after cutting and investigated whether different cutting procedures can affect the integrity of the posts. Six types of fiber posts were selected for this study (Carbon Fiber Posts, Quartz Fiber Posts, Aesthetic Posts, Aesthetic Plus Posts, Translucent Posts, Dentatus, FRC Postec Posts). Fifteen posts of each type were studied. ...
Local people are always dependent on cutting down and pollarding of Zagros forests trees to provide their livelihoods needs such as house heating, cooking, supply of livestock forage and building materials. The stakeholders also have many conflicts in terms of forest utilization, which is the main cause of many irregularities in the forest management. The present study was conducted to investig...
We study the space complexity of the cutting planes proof system, in which the lines in a proof are integral linear inequalities. We measure the space used by a refutation as the number of linear inequalities that need to be kept on a blackboard while verifying it. We show that any unsatisfiable set of linear inequalities has a cutting planes refutation in space five. This is in contrast to the...
The obstruction of the superior vena cava (SVC) of acute onset nature following surgery is a rare and serious condition. The tight closure of the pericardium over the heart during surgical procedures may cause external compression on the SVC. Echocardiography and Computed tomography (CT) scan aids in the diagnosis. Cutting open the pericardial stitches relieves the condition.
The balanced grazing is a critical managing factor regarding to resource conservation and quantitative and qualitative increase of plants production at the rangeland ecosystems. In addition, understanding the effects of different grazing intensity on the dominant plants can be used as a valuable tool in order to resource management. The current study aimed to determine vulnerability and toleran...
The nesting problem is an irregular two-dimensional cutting problem where the shapes of the pieces to cut and the master surfaces are irregular in shape and different in size. In particular, we consider nesting problems where the master surface could contain defects. Some of them can be accepted (i.e., incorporated) in certain types of pieces, while other defected areas must be avoided. The pro...
Modeling of bevel gear cutting processes requires highly flexible data structures and algorithms. We compare OpenMP3.0 tasks with previously applied approaches like nesting parallel sections and stack based algorithms when parallelizing recursive procedures written in Fortran 95 working on binary tree structures.
