Flat-Plate Solar Collectors The Absorption of Solar Radiation A flat-plate solar collector usually has a non-selective or a selective black plate with one or two glass covers a few centimeters above the black plate‚ and a well insulated back. The length of the plate is typically about 2m. Edge effects are usually small. The transmittance () of a glass cover for solar radiation depends on the angle of incidence . Typical values for clear glass are given in Table 1. Table 1. Transmittance of a Glass

India is the leading milk producing country in the world with a production of about 110 million ton per annum. The leaders of milk procurement in India‚ Anand Co-operative society followed by Nestle often face a scarcity of milk supply to meet their national and global demands particularly in summers. The major reasons for the less supply during the summers were analyzed and the study coined a term known as “Heat Stress”. Heat Stress is correlated to both ambient temperature and humidity level

transferred to another section. Which are evaporation‚ radiation‚ convection and radiation ( Jeng‚ 1998 ). Evaporation is when liquid changes into a vapor at a temperature below the boiling point. Evaporation takes place at the surface of a liquid‚ where molecules with the highest kinetic energy are able to escape. When this happens the average kinetic energy of the liquids is lowered and its temperature decreases ( The American Heritage‚ 2015 ). Convection is the transfer of heat by the circulation of

The storm was nearly 400 miles wide‚ with the highest recorded wind gust at 104 mph. Overall damages were estimated in the $1.0 billion dollar range‚ and three deaths were attributed to the Category 3 storm. Copyright © 2005 by The McGraw-Hill

Nervous System The nervous system is the part of an animal’s body that coordinates the voluntary and involuntary actions of the animal and transmits signals between different parts of its body. In most types of animals it consists of two main parts‚ the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS contains the brain and spinal cord. The PNS consists mainly of nerves‚ which are long fibers that connect the CNS to every other part of the body. The PNS includes motor

PLEASE READ ALL NOTES AND COME PREPARED FOR CLASSES 1. Diet has always played a vital role in supporting health. As a result‚ improper nutrition can put us at risk of becoming malnourished. Define the term malnutrition. Malnutrition means an incorrect or unbalanced intake of nutrients e.g. obesity‚ kwashiorkor… ……any condition caused by excess or deficient food energy or nutrient intake or by an imbalance of nutrients. 2a.

THERMOREGULATION IN THE NEONATE By: Shubhada Ponkshe [pic] INTRODUCTION: Thermoregulation is a critical physiologic function that is closely related to the transition and survival of the infant. An understanding of transitional events and the physiologic adaptations that neonates must make is essential to helping the nurse provide an appropriate environment and help infants maintain thermal stability. Optimizing the thermal environment has proven significant for improving the
