The correct estimate of individual thermal energy consumptions, and consequently, a fair heat cost allocation among the residents of apartment buildings with centralized heating systems, represents an important driving force towards energy saving, energy efficiency and the reduction of pollutant emissions. Nowadays, in those contexts where direct heat meters cannot be used because of the layout...

Eggs have a high nutritional value and are an important ingredient in many food products. Worldwide foodborne illnesses, such as salmonellosis linked to the consumption of eggs and raw egg products, are a major public health concern. This review focuses on previous studies that have investigated the procedures for the production of microbiologically safe eggs. Studies exploring pasteurization a...

in many reservoirs, after water flooding, a large volume of oil is still left behind. hot water injection is the most basic type of thermal recovery which increase recovery by improved sweep efficiency and thermal expansion of crude.in the present work, the effects of injection rate and the temperature of the injected water were surveyed by using core flooding apparatus. water flooding was perf...

ABSTRACT- In this study, texture profile analysis and a creep test were used to determine the textural quality attributes of fish protein isolates and conventional surimi. These isolates were made from raw materials obtained from filleting processes of Silver carp (Hypophthalmichthys molitrix) using acid and alkaline aided treatments. Texture profile analysis was performed in order to obtain ha...

Solar water heating system technology is described and the scale of the International solar water heater market is surveyed. New product developments for both direct solar water heating and solar boosted heat pump water heating are outlined. Procedures adopted by the International Standards Organisation for assessing solar water heater performance and quality are discussed.

background: acute low back pain is one of the most prevalent diseases which more than 90% of the adults experience at least once during lifetime. the present study was conducted to determine the efficacy of duration of hot water bag usageon pain relief in in the patients with acute low back pain. methods: this clinical trial study was conducted on 20- to 50-year-old patients referring orthopedi...

for over the past several decades, there has been a great concern about energy crisis and lackof non-renewable resources. residential buildings take more than 25% of the total energy consumption and morethan 75% of energy consumption in these buildings is for heating, cooling and hot sanitary water. on the other hand,traditional buildings of iran were designed according to ecological conditions...
