High-gain and low-profile antennas are required for high-speed wireless communication systems and mechanically-scanning automotive radars in the millimeter-wave band. Waveguide antenna is one of the most attractive planar antennas for such millimeter-wave systems because of its low loss and high efficiency characteristics in high frequency band. Travelling-wave excitation is more effective for ...

The present trial examined the possibility that diazepam (DZP, 1 mg/kg) induces hyperphagia by acting on the dopaminergic system. Quinpirole (QP), dopamine D-2 receptor agonist, was used for this purpose. Mice fasted for 24 hr were treated with QP 1 (QP-1) or 2 (QP-2) mg/kg 30 min prior to termination of the starvation. DZP was given to untreated mice and half of the QP-1 and QP-2 treated mice ...

This paper describes the performance analysis of different feeding technique for wireless microstrip patch antenna i.e for wi-max applications. In this paper four types of feeding techniques (Microstrip line feed, coaxial probe feed, proximity coupled feed and aperture coupled feed) are used. From the four feeding techniques, microstrip line and coaxial probe feeds are contacting scheme, in whi...

OBJECTIVE To compare the effect of different feeding frequencies on the speed of recovery from diarrhoea. METHODS A randomised, non-blinded trial provided 0.452 MJ/kg/day as either 6 or 12 feeds of cows' milk each day to 262 hospitalised male infants aged 3-12 months with acute diarrhoea. Stool frequency, stool weight, body weight, and diarrhoea complications were monitored until recovery or ...

BACKGROUND Insufficiencies in complementary feeding put infants and young children at increased risk of undernutrition. Till now, most Indian studies have looked at the individual level determinants of complementary feeding practices. We aimed to evaluate the association of frontline worker (FLW) provided nutritional counselling services, with change in community level indicators of complementa...

Feeding frequency (FF) remains an esoteric strategy in modern dairy production, because of multiple management factors affecting cow responses. The objective was to determine FF effects on eating, ruminating, and chewing behaviors of dairy cows in a non-competitive environment. Eight multiparous, early-lactation Holstein cows housed in individual box stalls received either once daily (1×) at 07...

conclusions herbal tea of fenugreek seed in comparison to the control group improves the signs of breast milk sufficiency. results before the intervention there was no significant difference between weight, height, head circumference, the number of wet diapers and frequency of defecation between the two groups (p > 0.05), yet the number of breast feeding times of the control group was more than...

A spider orb web is an extended phenotype; it modifies and interacts with the environment, influencing spider physiology. Orb webs are plastic, responding to variations in prey parameters. Studies attempting to understand how nutrients influence spider orb-web plasticity have been hampered by the inability to decouple prey nutrients from other, highly correlated, prey factors and the intrinsic ...

Background. Appropriate complementary feeding practice is essential for growth and development of children. This study aimed to assess dietary diversity and meal frequency practice of infants and young children in Ethiopia. Methods. Data collected in the Ethiopian Demographic and Health Survey (EDHS) from December 2010 to June 2011 were used for this study. Data collected were extracted, arrang...
