In New YorkCity from 1971 to 1975, only 1.6 per cent of all police firearms discharges involved the class of people police have since come to call emo tionally disturbed persons (EDPs). Still, because po lice were comparatively unrestrained in those years, the number of such incidents was quite large: 46, or better than 9 per year.1 In theyears since then, police shootings have declined dramati...

Trigeminal neuralgia (TN) is a disabling pain condition that has classically been treated using either surgical or medical techniques. Several researchers have shown that stereotactically delivered radiation can be an effective tool in the amelioration of this condition. For these studies, the Gamma Knife was used to deliver the radiation treatment. The target location was designated as the pro...

The annual incidence of traumatic spinal cord injury worldwide is estimated to be 35 patients per million. Nonmissile penetrating spinal injuries most commonly occur in the thoracic region, and the majority has neurologic deficits on admission. The management of patients who lack neurologic deficits is controversial due to the risk of neurologic status alteration intraoperatively. However, fail...

Background & Aim: A herbarium is a collection of preserved plant specimens. Herbarium specimens form an important recorded of what plants grew where over time. Kerman province with area about 171993 km2 has a lat of difference vegetation because of climatic and topography variations. It has different elevation (above sea level) from 300 m in Shahdad to 4420 m in Hezar mountains. Mat...

BACKGROUND Endovascular therapy (ET) is infrequently used in the setting of acute penetrating intracranial trauma. METHODS We report a case where ET was used immediately prior to and following removal of an embedded intracranial knife, which was found to be disrupting the anterior cerebral artery. RESULTS The proximal vessel was coiled and angiographically occluded and then the knife was re...

Trochlear nerve schwannomas are extremely rare. We present a surgically excised case of trochlear nerve schwannoma followed by Gamma Knife (ELEKTA, Stockholm, Sweden) after histologic confirmation. A 52-year-old man presented with diplopia, gait disturbance, and sensory disturbance. Magnetic resonance imaging demonstrated a large cystic mass at ambient cistern on the right side. Subtotal excisi...

The presented work deals with an analysis of causes the very low service life new version hand woodworking planing knife, which has replaced original a knife. Based on performed experimental works, chemical analysis, macroscopic and microscopic observation, SEM, diffractometric Vickers hardness test it was concluded that cause for (practically nonexistent one) knife are significant features ove...

in order to reduce herbicide utilization, a 3-year field experiment was carried out with integration of mechanical and chemical weed control methods; in mechanical method, three types of blades (curred- bed knife, square- turn knife and sweep) were used. chemical control was done with chloridazon (wp 80%) and desmedipham (ec 15.7%) in two spraying sheme: once band sparying with 2 l h-1 & twice ...

The knife-edge technique for measurements of micrometer-sized beams is extended to two-dimensional imaging by tomographic reconstruction of multiangular knife-edge data. Two-dimensional intensity distributions at optical (633-nm) and soft-x-ray (13.5-nm) wavelengths at the focal region of a Schwarzschild objective are presented. The resolution is limited by the 200-nm step size used in the data...
