background: gel polymers are considered as new dosimeters for determining radiotherapy dose distribution in three dimensions. objective: the ability of a new formulation of magic-f polymer gel was assessed by experimental measurement and monte carlo (mc) method for studying the effect of gold nanoparticles (gnps) in prostate dose distributions under the internal ir-192 and external 18mv radioth...
Localizing tactile stimuli on our body requires sensory information to be represented in multiple frames of reference along the sensory pathways. These reference frames include the representation of sensory information in skin coordinates, in which the spatial relationship of skin regions is maintained. The organization of the primary somatosensory cortex matches such somatotopic reference fram...
This article reconceptualizes residential care for older persons by introducing a framework developed from a rights-based principle of disability policies: the normalization principle. This principle is part of the social model and states that society should make available for people who have impairments living conditions that are as close as possible to those of "others." Using the framework o...
OBJECTIVE A general orientation along the cervical spine could be estimated by external landmarks, and it was useful, quick and less exposable to radiation, but, sometimes it gave reference confusion of target cervical level. The authors reviewed the corresponding between the neck external landmarks and cervical levels. METHODS Totally 1,031 cervical lateral radiographs of different patients ...
In this paper, a nonlinear model of the underactuated six degrees of freedom (6 DOF) quadrotor helicopter was derived based on the Newton-Euler formalism. A new nonlinear robust control strategy was proposed to solve the stabilizing and path following problems in presence of external disturbances and parametric uncertainties. The proposed control structure consist of a sliding mode control base...
BACKGROUND In a previous study PCR analysis of clinical samples from suspected cases of Buruli ulcer disease (BUD) from Togo and external quality assurance (EQA) for local microscopy were conducted at an external reference laboratory in Germany. The relatively poor performance of local microscopy as well as effort and time associated with shipment of PCR samples necessitated the implementation ...
the present research is representing a template for coordination between human resources strategies and organizational structure and its effect on organizational performance. three alignment (coordination) theories could be identified in management literature; logical pattern, natural pattern and strategic refrence point pattern. in this research after a review on the philosopphical and logical...
