Background and aim s : The correct assessment of volatile organic compounds is a main stage of their control's action plan. Needle trap device (NTD) as a novel technique with all advantages of microextraction methods, is an inexpensive and rapid technique for survey of air pollution agents. In this study the performance of this technique was investigated for sampling and analysis of organohal...
In this study, the performance of a solar greenhouse heating system equipped with a linear parabolic concentrator and a dual-purpose flat plate solar collector was investigated using the Artificial Neural Network (ANN) method. The heat required for the greenhouse at night hours was supplied by the heat stored in the storage tank by the solar system during the sunshine time and an auxiliary he...
Oysters are bivalve molluscs in the family Osteridae of the order Ostereoida and are found throughout the world. Quality of stored muscle of oyster, Crossostrea glomerata depends on the temperature and storage time. Investigation on factors responsible for spoilage of oyster meat in refrigerator (7±2°C); in term of biochemical indices, indicated that in 1-2 days the following changes will accur...
Background: Chicken fillets contain essential amino acids besides many minerals and vitamins, which are necessary for maintaining life and promoting growth. Moreover, it is low in calories and cholesterol; therefore, it can be used for feeding infants, young children, and some patients. Methods: Chicken fillets were initially coated by dipping in different concentrations of chitosan (1.0%, 1.5...
For the continuous production of electricity with solar heat power plants the storage of heat at a temperature level around 400 degrees C is essential. High temperature metal hydrides offer high heat storage capacities around this temperature. Based on Mg-compounds, these hydrides are in principle low-cost materials with excellent cycling stability. Relevant properties of these hydrides and the...
objective: the aim of this study was to evaluate the dimensional stability of casts made from an alginate impression material poured immediately and stored after specific periods. materials and methods: the common alginate used in iran (super; iralgin, golchai co., tehran, iran) was tested. a master model was mounted on a special device and used to obtain the impressions. these impressions were...
compressed biscuits (cbs) were developed using wheat flour, soy flour, sugar, oil and malt extract. combining of compression and dehydration technology were applied for production. packaging cbs using vacuum packaged, use of oxygen absorber (oa) and identical samples were aerobically packaged and stored at ambient and elevated (40°с) temperature for 12 weeks. the effect of different packaging a...
Background: Blackberry is a seasonal harvested fruit that is also very fragile and perishes quickly. A comparative study was conducted to find out influence of cold storage on physicochemical parameters of wild and cultivated blackberry over a period of 12 days. Methods: The plant materials were composed of the blackberry fruit, including a compound of cultivated blackberry (Rubus spp.), and w...
We observed the influences of low-temperature storage of the feline epididymis on the epididymal semen qualities before and after cryopreservation to identify the optimal duration for low-temperature storage of the epididymis. After excision, the feline epididymis was stored at 4 degrees C for 0-72 hr and then subjected to epididymal sperm collection. When sperm from the refrigerated cauda epid...
Physicochemical characteristics of potato (Solanum tuberosum L.) are very important for storage and processing qualities. The amount of reducing sugars (glucose and fructose) and organic acids at harvest, during and after storage is the most important factor. In this study, three potato cultivars (Moran, Marfona and Agria) were collected, dry cleaned and graded into three sizes. They were analy...
