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...

AIM To probe into problems existing in gamma knife treatment of ophthalmic branch of primary trigeminal neuralgia (TN), and propose a safe and effective solution to the problem. METHODS Through sorting the literature reporting gamma knife treatment of refractory TN in recent years, this article analyzed the advantages and problems of gamma knife treatment of primary TN, and proposed reasonabl...

BACKGROUND Stereotactic radiosurgery (SRS) is a widely used therapy for brain metastases(BMs) in Non-small cell lung cancer(NSCLC). However, its role in symptomatic patients with EGFR mutation remains unclear. We have retrospectively reviewed the clinical data of patients with symptomatic BMs whom received SRS as a salvage approach and concurrent gifitinib therapy. METHODS Seven patients with...

Preservation of the remains and the inclusion of small amounts of other species (particularly the human bones) suggests that the bones were redeposited and probably represent fellmongers refuse. The low incidence of butchery marks implies that the horse bones are unlikely to be the remains of animals slaughtered for human consumption, the few knife and chop marks probably being associated with ...

Docking by knife or elastrator had no sustained effect on growth of lambs 0 to 8 wk postpartum. However, during the 2 wk period postdocking, growth of lambs was limited or depressed, regardless of whether lambs were docked by knife at 14, 28 or 42 d of age. Blood hematocrit and hemoglobin were decreased (P less than .01) 1 d after docking by knife and 14 d after docking by elastrator. Neither m...

This paper addresses the problem of motion Chaplygin sleigh, a rigid body moving with three points in contact horizontal plane. One them is equipped knife edge along which there no slipping. Special attention given to case where dry friction present at one support without edge. The equations are written, normal reactions calculated, and behavior phase curves neighborhood an equilibrium point, d...

The base sledge microtome presents a hazard to the operator due to the length of blade that is exposed. Manipulation of the carriage requires hand movements close to the knife edge and serious lacerations may result. A simple, effective guard has been devised, suitable for knives which have screw holes for handles at both ends. It consists of two perspex end-pieces (Fig. I), attached to the kni...

OBJECTIVE To describe cases of intra-orbital knife blade foreign body following stabs to the orbit, together with a novel technique for removal. METHODS Retrospective case series of 3 patients. RESULTS All 3 patients had knife blades embedded in the orbit as a result of assault. The blades assumed the same direction within the orbit with varying degrees of depth, one causing serious vascula...

The Gamma Knife Check software is an FDA approved second check system for dose calculations in Gamma Knife radiosurgery. The purpose of this study was to evaluate the accuracy and the stability of the commercial software package as a tool for independent dose verification. The Gamma Knife Check software version 8.4 was commissioned for a Leksell Gamma Knife Perfexion and a 4C unit at the Univer...

This paper proposes a cake-cutting protocol using cryptography when the cake is a heterogeneous good that is represented by an interval on a real line. Although the Dubins-Spanier moving-knife protocol with one knife achieves simple fairness and truthfulness, all players must execute the protocol synchronously. Thus, the protocol cannot be executed on asynchronous networks such as the Internet....
