in the present study, theoretical chemical reactivates photo isomerization in cis-retinal as a natural photo switch in vision. dft hybrid functional, b3lyp and, post-hf method, were the theoretical methods applied utilizing g09 software. 6-31g+ (d,p) basis set employed for structural optimizations, and single point computations performed using b3lyp/6-31g+(d,p). the isomers cis molecule retinal...

Conventional anthropometry of the adult has been limited largely to measurements that may be made with the anthropometer, the tape measure, and the calipers. The dimensions are linear, and they relate to the body surfaceheights of body landmarks, widths, circumferences, and spans between surface points. To be duplicable, the measurements must he made in the same manner on different individuals,...

Sao Paulo Med J 2003; 121(4):147-148. The use of anthropometric references for the evaluation of intrauterine growth has shown that children whose growth was restricted are more predisposed to metabolic disturbances during the neonatal period, alterations in somatic and neurocognitive development during infancy, increased morbidity and mortality in the first years of life and the appearance of ...

Background & Aims of the Study: Phenolic compounds have been extensively used in industries for applications such as petrochemical, oil refineries, papers, plastics, steel, pharmaceuticals, textiles, coal conversion, and so on. Specified amounts of Phenolic compounds are lost in the process of their manufacturing and utilization and often cause environmental pollution problems....

background: anthropometry is a branch of ergonomics that considers the measurement and description of the human body dimensions. accordingly, equipment, environments, and workstations should be designed using user-centered design processes. anthropometric dimensions differ considerably across gender, race, ethnicity and age, taking into account ergonomic and anthropometric principles. the aim o...

background: the goal of the present work was to determine frequencies of different finger patterns of a population in hamadan (one of the western cities of iran) in 1997. methods: in a cross-sectional study, the .prints of the first phalanx of both hands of 717 randomly selected hamadan students (i88 men, 529 women) have taken, by using standard method (stamp ink). the fingerprints were classif...

introduction: the human anthropometric characteristics are surveyed in anthropology. anthropology is used in archeology, rehabilitation and legal medicine. the purpose of this study was to determine femur which has a special place in the science of anthropometry. methods: to measure the femur, both direct and indirect methods was used. the direct method of measuring the 113 femur in dissection ...

In this work the performance of a wavelength division multiple access (WDMA) system with direct detection receiver is investigated. For this purpose, the probability of error in a WDMA network with OOK modulation considering crosstalk, ISI, photo detector noise and thermal noise is calculated and the effect of each on system performance is investigated. The system performance in presence of PIN...

Preedy (ed.), Handbook of Anthropometry: Physical Measures of Human Form in Health and Disease, DOI 10.1007/978-1-4419-1788-1_1, © Springer Science+Business Media, LLC 2012 Abstract Sample size estimation is a fundamental step when designing clinical trials and epidemiological studies for which the primary objective is the estimation or the comparison of parameters. One may be interested i...
