in iran we already use laminate tubes only in cosmetics industry. laminate tube manufacturers via using the most modern technology of the world, faced with the laminate tube market being saturated in cosmetics industry for packaging the cosmetic creams and toothpaste. but considering the great food market and therefore laminate tube features such as beautiful packaging, ease of use for the fina...
objective: to assess and compare the nutritional status of children aged 5-14 years in arsenic exposed and non- exposed areas. materials and methods: it was a cross sectional study conducted on 600 children of age 5-14 years from arsenic exposed and non-exposed areas in bangladesh. designed questionnaire and check list were used for collection of data. to estimate bmi necessary anthropometric m...
دیواره آبی غشایی به عنوان سطح جاذب حرارت ، برای تولید بخار، در اکثر دیگهای بخار لوله- آب ، مورد استفاده قرار می گیرد. این دیواره، باید در شرایط مختلف بهره برداری، بسیار قابل اطمینان و ایمن باشد. در رساله حاضر، تغییرات درجه حرارت ، توزیع دما و نحوهء انتقال حرارت هدایتی، در داخل جدارهء دیواره آبی دیگهای بخار لوله-آب ، مورد بررسی قرار گرفته است . شناخت رفتار حرارتی فلز و انتخاب نوع آن و نیز آگاهی ...
Although the multiplication of bacteriophages (phages) has a substantial impact on the biosphere, comparatively little is known about how the external environment affects phage production. Here we report that sub-lethal concentrations of certain antibiotics can substantially stimulate the host bacterial cell’s production of some virulent phage. For example, a low dosage of cefotaxime, a cephalo...
In this paper, a forced circulation solar water heater system is simulated for different hot water consumption profiles using flat plate collectors as well as evacuated tube collectors. The profiles studied are the actual samples of hot water consumption profiles for different commercial centers and institutions. Dynamic simulation outputs of system thermal performance are used as economic anal...
The aim of the present study was to evaluate the levels of arsenic in tube-well water, food and residents' urines samples in Yatenga province, Burkina Faso. The prevalence of skin lesions was evaluated as well. The study was cross-sectional in design. It was conducted during April 2009. Permanent residents of 20 villages were included in the study. Water samples were collected from 31 tube-well...
The reliability of water in riverbank filtration application is hard to be determined since the source and what happen at below ground cannot see. These difficulties give effect for it important determination its quality quantity. Due that, this method was suggested used determine pumping well (PW) Lubok Buntar, Kedah. soil samples were taken from PW river type major ion (anion cations). result...
background: magnetized water has made many improvements in industry, agriculture and medicine. however its utilization in medicine still remains controversial. objective: in this study we aimed to investigate the effects of magnetized water on height of epithelial cells in pre-implantation stage endometrium and fallopian tube and number of corpus lutea in female mice. materials and methods: e...
the effect of γ-al2o3 nanoparticles on heat transfer rate, baffle spacing and pressure drop in the shell side of small shell and tube heat exchangers was investigated numerically under turbulent regime. γ-al2o3-water nanofluids and pure water were used in the shell side and the tube side of heat exchangers, respectively. since the properties of γ-al2o3-water nanofluids were variable, they were ...
