Studying gear power loss theoretically and determining the efficiency of a helical drive depend on many geometrical working parameters, such as rotation speed, tooth number, ratio, helix angle, torque, among others. In this paper, Plackett–Burman screening design Box–Behnken response-surface method are used to consider how above parameters influence efficiency, experimental models provided eval...

potassium chloride (kcl) is a highly water soluble substance which is usually used to prevent hypokalemia. oil in water disperse phase encapsulation method was used to prepare kcl loaded microcapsules using beeswax and carnauba wax as a hydrophobic matrix. the morphology and characteristics of kcl loaded microspheres were studied using scanning electron microscopy (sem), photon correlation spec...

This book offers a comprehensive description of the phonetic and phonological features of Sumi, a Tibeto-Burman language of Nagaland, North-east India. It represents the first in-depth investigation of the acoustic phonetics and phonology of tone in Sumi, and is one of the first extensive acoustic descriptions of a language of Nagaland. The book describes the segmental phonology, syllable struc...

Aspirated fricatives are typologically rare in world’s languages, occurring mostly in the Sino–Tibetan languages. However, they are hitherto unreported in the Tibeto–Burman languages spoken in North–East India. In this study we present data from Bodo, a Tibeto–Burman language spoken in Assam, India and argue that the Bodo voiceless alveolar fricative is an aspirated voiceless alveolar fricative...

Dammarane-type saponins (DTSs) exist in various medicinal plants, which are a class of active ingredients with effects on improving myocardial ischemia and immunomodulation. In this study, quantitative 1H NMR method total DTSs herbal medicines was developed based the analytical procedure lifecycle. first stage (analytical design), Ishikawa diagram failure mode criticality analysis were used to ...
