The shoot diameter and shoot length extension growth studied in 10 tree species occurring between 350 to 2500 m elevation in the Kumaun Himalaya. Effects of temperature on shoot growth were studied under natural conditions. Shoot length growth was significantly affected by the temperature during shoot elongation (p<0.01). The optimum temperature for elongation was ranged from 21 to 36°C across the altitudinal... Read more.

Investigating the response of rain-fed maize to fertility levels and weed management practices, a field trial was undertaken in 2012 and 2013 at Experimental Farm, D(K)ARS, SKUAST-Kashmir, (J&K). The experiment consisted of 3 fertility levels and 4 weed management practices. The results revealed that fertility levels F3 and F2 at par with one another recorded significant increase in cob length, number of cobs... Read more.

A chronic complication of diabetes mellitus (DM), diabetic neuropathy, causes neurodegeneration leading to the development of neuropathic pain and sensation loss, particularly in the hands and arms. The cervical enlargement of the spinal cord sends the nerve supply to the hands and arms. Moreover, astrocytes effectively provide structural and functional maintenance of neurons in the spinal cord. Nevertheless, there is... Read more.

Photoplethysmogram (PPG) and its second derivative of the photoplethysmogram (SDPTG) are simple and low cost optical techniques for detecting and tracking blood volume changes. The PPG waveform and its SDPTG have been used by many scholars to obtain valuable information about heart and cardiovascular system. Since PPG and SDPTG reflect blood volume changes, much work has been done on its application as a diagnostic tool... Read more.

This paper examines a consequence of spinodal curve condition on the Joule – Thomson inversion curves, for van der Waals real gas. To this end, we consider the differential form of Joule – Thomson coefficient, and concentrate on the parametrical algebraic equation of the corresponding family of curves in a P – V Cartesian frame of reference. The aim of this work is not the prediction of Joule... Read more.

The vegetation fraction over the Ethiopian highlands exhibits large seasonal and multi-annual variability in the period 1982 to 2014. Northern areas are more sensitive to rainfall due to the brevity of the wet season. Differences in the regional climate during periods of high and low vegetation are analyzed using composite fields of rainfall, wind, humidity, sea temperatures, salinity and currents; and correlations at...
