BACKGROUND In October 2007, a cluster of patients experiencing a novel polyradiculoneuropathy was identified at a pork abattoir (Plant A). Patients worked in the primary carcass processing area (warm room); the majority processed severed heads (head-table). An investigation was initiated to determine risk factors for illness. METHODS AND RESULTS Symptoms of the reported patients were unlike p...

Clustering is a technique that can effectively reduce the energy consumption of sensor nodes. In self-organizing clustering strategies, sensors elect themselves to be cluster-heads independently. This cannot guarantee the even distribution of cluster-heads over the entire sensor-network field or even the election of an optimal percentage of cluster-heads. We proposed Two-Tier Clustering in [1] ...

OBJECTIVE To assess the anatomical variations of the pronator teres muscle (PTM) and its implication in the compression of the median nerve, which passes through the humeral and ulnar heads of the PTM. METHODS For the present study, 100 upper limbs from human cadavers from the anatomy laboratory were dissected. Forty-six specimens were male and four, female, whose aged ranged from 28 to 77 ye...

This study examines the influence of the position of prosodic heads (accented syllables) and prosodic edges (prosodic word and intonational phrase boundaries) on the timing of head movements. Gesture movements and prosodic events tend to be temporally aligned in the discourse, the most prominent part of gestures typically being aligned with prosodically prominent syllables in speech. However, l...

knowledge on animal requirement, available forage and its quality is fundamental for successful livestock and range management. since sheep is dominant grazing animal of rangelands in iran and there are over 27 sheep breeds and each breed has special body size, physiological condition and consequently different daily nutrition requirement, animal unit should be determinated for dominant breed o...

Introduction: During the last decades, simulation of radiation therapy treatment conditions in treatment room for studying with more details in comparison with treatment planning system (TPS) is taken into consideration. The most problem with starting these kind of researches is the geometry of Medical linacs and verification of the accelerators. Therefore, researchers tried to...

In Wireless Sensor Networks (WSN), the clustering protocol requires the nodes local information like energy level, distance between to BS and node density, link quality and load while estimating the cluster heads to handle network lifetime. In this study, we propose fuzzy based optimal clustering protocol for maximizing lifetime in WSN. Initially, several provisional cluster heads are elected i...

To address the clinical problems of joint stiffness, acetabular pain, and component wear, recent bipolar heads have been designed to achieve increased inner bearing range of motion. We tested four designs to determine if this compromises component integrity. Inner bearing ranges of motion were determined and the components then mechanically tested to determine inner bearing pull-out disassociat...

In the Minimalist Program (Chomsky, 1992) it is assumed that there are diierent types of projections (lexical and functional) and therefore diierent types of heads. This paper explains why functional heads are not treated as head-corners by the minimalist head-corner parser described here.
