controlling is a very important function of every manager. controlling is based and closely related to planning or the first function of management. these two functions are so related to each other that may be viewed as the blades of a pair of scissors. the scissors can not work unless there are two blades. without plans, control is not possible. theoretically, the concept of concept of control...

background controlling parenchymal hemorrhage especially in liver parenchyma, despite the progress in surgical science, is still one of the challenges that surgeons face when trying to save patients’ lives. researchers in the field are challenging to introduce a more effective method. objectives the current study aimed to determine the haemostatic effect of alum [kal (so4)2] and compare it with...

results the hemostatic time of aluminum chloride 50%, 25%, 15%, 10% and 5% were 8.20 ± 0.919, 14.10 ± 1.37, 21.20 ± 1.31, 30.80 ± 1.68 and 42.00 ± 4.19 seconds, respectively. also, the mean hemostasis time in the control group (suture) was 84.00 ± 4.05 seconds. the hemostatic times of different concentrations of aluminum chloride were significantly less than that of the control group. there was...

We developed a simple preparation procedure for the protein encapsulated nanoparticle and used the nanoparticle for spatiotemporal activity control of various proteins. We succeeded in the local protein activation within cells by light using the nanoparticle.

Elastic ray theory is a high frequency asymptotic approximation of solution of elastodynamic equation, and is widely used in seismology. In this paper, the form invariance under a general spatial mapping and high frequency wave control have been examined by transformation method. It is showed that with the constraint of major and minor symmetry of the transformed elastic tensor, the eikonal equ...

The control of disturbances due to fuel quality variation is important development area in the grate combustion technology. Main challenges in the control of the grate combustion are inhomogeneous fuel, variation in fuel moisture content, non-uniform distribution of fuel on the grate area and high percentage of combustibles in ash. Information on events which occur in the furnace plays an impor...

An efficient method to tune the spatial coherence of a degenerate laser over a broad range with minimum variation in the total output power is presented. It is based on varying the diameter of a spatial filter inside the laser cavity. The number of lasing modes supported by the degenerate laser can be controlled from 1 to 320,000, with less than a 50% change in the total output power. We show t...
