anthropometry is the study of human body dimensions and proportions among different races. in work environments, poorly designed workstations and tools reduce productivity and can lead to fatigue and musculoskeletal injuries. this study aimed to determine the anthropometric characteristics of iranian workers in comparison to three other asian countries. this cross-sectional study evaluated 400 ...

PURPOSE The goal of the present study was to develop a poly (ethylene oxide) N10 (PEO N10) based melt-cast matrix system for efficient and prolonged delivery of hesperetin (HT), a promising bioflavonoid, to the posterior segment of the eye through the topical route. METHODS HT film was prepared by melt-cast method using PEO N10 and cut into 4mm×2mm segments, each weighing 8mg. This film was e...

Three techniques for measuring methotrexate show various cross reactivities with methotrexate-related compounds: "high-pressure" liquid chromatography, by principle, is virtually specific for methotrexate; the enzyme-inhibition assay quantitates methotrexate, methotrexate diglutamate, and methotrexate triglutamate equally well, but has a 10% cross reactivity with 4-amino-4-deoxy-N10-methylptero...

OBJECTIVE To determine the amplitude changes of vestibular evoked myogenic potentials (VEMPs) recorded simultaneously from the neck (cVEMPs) and eyes (oVEMPs) in response to 500 Hz, 2 ms air-conducted sound pips over a 30 dB range. METHODS Fifteen healthy volunteers (mean age 29, range 18-57 years old) and one patient with unilateral superior canal dehiscence (SCD) were studied. The stimulus ...

background: in most armies, clothes, equipment and weapons are designed according to the physical characteristics and anthropometric data of soldiers. objective: to study the anthropometric characteristics of iranian army force and their changes over recent years. methods: 12 635 iranian military personnel aged between 18 and 30 years with tenure of <10 years who were normally engaged in educat...

materials and methods in this descriptive and analytical study, we used a static and direct method. cluster sampling method was used to select the subjects. participants were 1600 randomly-selected iranian male (n = 568) and female (n = 1031) workers of five hospitals in bandar abbas. thirty seven static dimensions were measured in the individuals aged 20 - 60. for anthropometric measurement, t...

As the design of a workstation can have significant effects on user fatigue, safety and user performance, ensuring that the workstations used in any work systems are agreeable with the principles of anthropometrics have become so important. In this research, a library furniture set (table and chair for student) currently used at a Main Library, St.Maty’s Engineering College, has been evaluated....

In this paper, fabrication of silicon microchannels with integrated obstacles by using 25 wt.% tetramethylammonium hydroxide (TMAH) aqueous solution at the temperature 80?C is presented and analysed. We studied basic island patterns, which present union two symmetrical parallelograms sides along predetermined crystallographic directions &lt;n10&gt; (2&lt;n&lt;8) &lt;100&gt;. Acute angles were s...

UNLABELLED This study measured 21 anthropometric dimensions (ADs) of 94 Korean male helicopter pilots in their 20s to 40s and compared them with corresponding measurements of Korean male civilians and the US Army male personnel. The ADs and the sample size of the anthropometric survey were determined by a four-step process: (1) selection of ADs related to helicopter cockpit design, (2) evaluati...

PURPOSE To characterize the recording and analyze the results of the combined cervical and ocular vestibular evoked myogenic potential in individuals without hearing and vestibular complaints. METHODS In this study, 30 individuals without hearing complaints and hearing within normal limits were evaluated. Data were collected through the simultaneous recording of cervical and ocular vestibular...
