today, in the rangeland management science and determination of rangecapacity, accurate and true information about range production is crucial. in fact, rangeproduction is considered as a basis for range management. the aim of this study was tocompare different methods for the estimation of forage production with four samplingmethods in the rangelands of kurdistan province, iran. the sampling m...

plant biomass is an important factor for determining arid and semi-aridrangelands capacity. due to the lack of proper and annual sampling of rangelands, there areno suitable data to determine biomass, range condition and proper range managementoperations. plant biomass is one of the measurable attributes that can be assessed inrangeland studies. since the clip and weight method is destructive a...

background: management of intracranial aneurysms has made debates about the best treatment modality in recent years. the aim of this study was to compare the interventional outcomes between two groups of patients, one treated with endovascular coiling and the other treated with surgical clipping. methods: this prospective study included 48 patients with intracranial aneurysms who underwent endo...

The objective of this study was to determine the chronology of changes in blood pressure in renalhypertension induced by solid plexiglass clips in rats. Saw blades with the thickness of 0.21-0.22 mm wereused to make clips sized 4 × 2 × 2 mm from a piece of 2-mm thick plexiglass. Rats were subjected to shamoperation or left renal arterial clipping, and 1, 2, 3 and 4 weeks later blood pressure, a...

one method of treating ruptured anterior communicating aneurysms is presented. this permits early clipping through a bifrontal flap. key branches of the circle of willis are temporarily occluded by special removable clips before exposing and permanently clipping the aneurysm. this requires the use of hypothermia at 28'0. and other technical aids described. the risk of a fatal recurrent hemorrha...

General relativity is notoriously difficult to interpret. A "return to the mothers" is proposed to better understand the gothic-R theorem of the Schwarzschild metric of general relativity. It is shown that the new finding is already implicit in Einstein's equivalence principle of 1907 and hence in special relativity (with acceleration). The TeLeMaCh theorem, named onomatopoetically after Telema...
