BACKGROUND Retinal cotton-wool spots (CWSs) are an important manifestation of retinovascular disease in hypertension (HTN) and diabetes mellitus (DM). Conventional automated perimetry data have suggested relative scotomas in resolved CWSs; however, this has not been well delineated using microperimetry. This study evaluates the retinal sensitivity in documented resolved CWSs using microperimetr...

We characterized the perceptual, functional, and structural abnormalities associated with retinal ischemia during a cotton wool spot episode and its sequelae. The border of the visually salient field anomaly mirrored the quantitatively measured relative scotoma. Results of resolution perimetry and high resolution imaging indicated that there was a substantial loss of retinal ganglion cells with...

Air drag on yarn and package surfaces affects yarn tension, which in turn affects energy consumption and ends-down in ring spinning. This paper investigates the effects of yarn hairiness on air drag in ring spinning. Theoretical models of skin friction coefficient on the surface of rotating yarn packages were developed. The predicted results were verified with experimental data obtained from co...

Coronavirus disease 2019 (COVID-19) has been declared as worldwide pandemic. The most common symptoms are fever, fatigue, flu-like syndrome and accompanied by respiratory distress. About 10% of patients with COVID-19 in the acute phase show manifestations eye, especially retina. activity cell surface enzyme protein angiotensin-converting 2 (ACE2) is believed underlying clinical eye. This study ...

Yarn properties can be altered through blending fibres. According to the requirement different properties can be achieved by different blending ratios. Among the different blends cotton and polyester, cotton and wool, wool and acrylic, cotton and nylon, jute and acrylic, cotton and rayon etc are common. Flax and polyester has been a popular blend now-adays and depicts excellent properties than ...
