The sense of touch is represented by neural activity patterns evoked by mechanosensory input forces. The rodent whisker system is exceptional for studying the neurophysiology of touch in part because these forces can be precisely computed from video of whisker deformation. We evaluate the accuracy of a standard model of whisker bending, which assumes quasi-static dynamics and a linearly tapered...

Simulation of the milling process is a widespread method to improve productivity in the machining process. Several phenomena can be studied and controlled by this mean. All the simulation methods need parameters that characterize the interaction between the tool and the workpiece in order to evaluate the cutting forces. Many models were developed to link efforts to macroscopic parameters (depth...

researchers are of the belief that employee voice has favorable effects for both the employee and the organization. however, the effect of employee voice on creativity, and the process through which it influences creativity, has hitherto received little attention. this study aimed at investigating the relationship between perceived employee voice and creativity. employees of three premier dairy...

A mechanistic description of the generation of whisker movements is essential for understanding the control of whisking and vibrissal active touch. We explore how facial-motoneuron spikes are translated, via an intrinsic muscle, to whisker movements. This is achieved by constructing, simulating, and analyzing a computational, biomechanical model of the motor plant, and by measuring spiking to m...

the phenomenon of war has always caused redefining new scientific horizons and areas in societies, which next generations can use them too. because of threatening the entity of a nation, it causes implementing all mental, intellectual and practical strengths of a community, to be used. one of the most used knowledge's in the war, has been management. on the other hand, the dominant organiz...

the interaction between [pt(phen)(pyrr-dtc)]no3 (where phen = 1,10-phenanthroline and pyrr-dtc =pyrrolidinedithiocarbamat) with human serum albumin (hsa) was studied by fluorescence, uv–vis absorption, circular dichroism (cd) spectroscopy and molecular docking technique under like physiological condition in tris–hcl buffer solution at ph 7.4. uv-vis absorption spectroscopy indicates that the pro...

interaction of drugs with serum albumin, the most abundant protein in plasma, has a great significance in pharmaceutical sciences. it can affect the biological activity, toxicity, and pharmacokinetics of drugs and design of dosages. determination of the impact of chemical modifications of albumin and its structural changes upon interaction with drugs are very important when drugs bind with albu...

PLACE AND DURATION OF STUDY Fauji Foundation Hospital, Foundation University Medical College and Armed Forces Institute of Pathology, Rawalpindi, from January 2011 to June 2012. METHODOLOGY A total of 120 patients of megaloblastic anaemia we...

statement of problem: primary teeth discoloration can cause mentally and socially unpleasant effects in children. this can also be a sign of systemic disease. despite the importance of this subject, a comprehensive study has not been performed yet. purpose: the aim of this study was determining the frequency of different types of primary teeth discoloration. materials and methods: in this cross...

When two droplets with different surface tensions collide, the shape evolution of merging is asymmetric. Using experimental and numerical techniques, we reveal that this asymmetry caused by asymmetric capillary waves, which are result droplets. We show enhanced increasing tension difference, suppressed inertia colliding Furthermore, study waves in limit no inertia. not directly Marangoni forces...
