We investigate experimentally liquid (oil) droplets vibrating over a bath of the same liquid and relate the phenomenon to the well-known effect of the stabilization of an inverted pendulum on a vibrating foundation (a “Kapitza pendulum”). Small fast vibrations can be substituted by an effective “levitation” force. We further discuss this effective stabilizing “spring force”. Besides the inverte...

Fermentative bioethanol production from pyrolytic sugars was improved via aromatics removal by liquid-liquid extraction. As solvents, the ionic liquid (IL) trihexyltetradecylphosphonium dicyanamide (P666,14[N(CN)2]) and ethyl acetate (EA) were compared. Two pyrolytic sugar solutions were created from acid-leached and untreated pinewood, with levoglucosan contents (most abundant sugar) of 29.0% ...

OBJECTIVE The aim of this study was to determine if the association with adiposity varies by the type (added vs. naturally occurring) and form (liquid vs. solid) of dietary sugars consumed. METHODS Data from the 10-year National Heart, Lung, and Blood Institute (NHLBI) Growth and Health Study (n = 2,021 girls aged 9-10 years at baseline; n = 5,156 paired observations) were used. Using mixed l...

Consumption of liquid oral medicine by frequently ill children, significantly increases the risk of tooth demineralization. In this study a survey was conducted wherein the pediatricians, pharmacist and medical representatives of Bhopal city were enquired about the most commonly prescribed liquid oral medicines for children. The four categories of medicines reported were: antipyretics/analgesic...

while weeds in sugar beet farming reduce crop yield and quality, they also lead to higher labor and material losses. in recent years, in order to eliminate or reduce the damage caused by weeds in sugar beet farming, weed control has gained importance. to this end, various studies have been conducted on robotic weed control by detecting weeds using image processing algorithms and hoeing or spray...
