This paper deals with the Basic communication model and the types of fibers for the optical fiber communication system. Then the different technologies in optical fiber communication along with their features are discussed briefly. Some comparisons of optical signals with the traditional electrical signals are explained concisely. Finally the general system of optical fiber communication is bri...

Abstract As the Thirty Years’ War was greatest demographic crisis in Europe between Black Death and two World Wars, it is unsurprising that conflict created number of refugees continent’s history prior to twentieth century. However, limited scholarship on displaced persons 1618 1648 has been exclusively based micro-level eyewitness accounts, diaries, memoirs. This article broadens scope studies...

Glycosylated α-dystroglycan provides an essential link between extracellular matrix proteins, like laminin, and the cellular cytoskeleton via the dystrophin-glycoprotein complex. In secondary dystroglycanopathy muscular dystrophy, glycosylation abnormalities disrupt a complex O-mannose glycan necessary for muscle structural integrity and signaling. Fktn-deficient dystroglycanopathy mice develop...

Serial evaluation of diffusion tensor brain fiber tracking was performed in a 27-year-old female patient with diffuse axonal injury after a traffic accident. Although the result of brain fiber tracking was not necessarily parallel to her clinical symptoms, it may have predicted the neurologic prognosis.

The current study was conducted to survey the influences of addition of alfalfa meal (AM), rice bran (RB) and wood shaving (WS) in wheat-based diets [contain soluble non starch polysaccharides (NSP)] on performance carcass characteristic and serum lipids of broilers from 11 to 42 d of age. Seven hundreds 10-d-old male Ross 308 chicks were placed into 35 pens and allocated to seven wheat-soybean...

SUMMARY We report DTI and fiber tractography findings in a case of hypertrophic olivary degeneration. A 51-year-old man presented with an abnormal gait and visual difficulties. MR imaging showed enlargement of the right medullary olive and a vascular lesion in the right pontine tegmentum. Fiber tractography showed decreased volume of the right central tegmental tract, supporting a diagnosis of ...

We report a case of Parry-Romberg syndrome in a 32-year-old woman presenting with intermittent headache and mild sensory disturbance. MR imaging revealed minimal asymmetric atrophy of the right hemisphere with a few nonspecific white matter hyperintensities. Diffusion tensor imaging and fiber tractography, however, demonstrated clear fiber derangement, especially in the sensory tract of the rig...

The influence of caloric restriction (CR) initiated at 17 months of age was investigated on selected age-associated measures in skeletal muscle. Tissue from young (3-4 months) ad libitum-fed, old (30-32 months) restricted (35% and 50% CR, designated CR35 and CR50, respectively), and old ad libitum-fed rats (29 months) was studied. CR preserved fiber number and fiber type composition in the vast...

to study the fleece characteristics of native goats in sistan and balouchestan province, fiber sample was taken from 270 females between one to three years old from khash, saravan and iranshahr cities. the differences between age groups for all fleece parameters except fleece weight were not significant. the fleece weight of two and three years old goats were 263.4 (± 7.7) and 315 (± 7.8) gr, r...

Different paper grades have been used to evaluate the optical formation measurements for newsprint and SC paper. Formation of the SC papers has been measured both before and after supercalendering to see how it affects the optical measurements. The optical measurements have been compared to β-radiation measurements and the results showed that optical measurements give a fair estimation of the f...
