today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...
Investment casting is a versatile manufacturing process to produce high quality parts with high dimensional accuracy. The process begins with the manufacture of wax patterns. The dimensional accuracy of the model affects the quality of the finished part. The present study investigated the control and optimization of dimensional deviations in wax patterns. A mold for an H-shaped wax pattern was ...
Background: Waste of health care centers is particularly important due to their major role in spreading various diseases and environmental pollution. Consequently, considering function of non-hazardous waste devices in hospitals seems vital. This study is aimed to assess function of non-hazardous non-incineration devices of waste in Kerman educational hospitals and Sirjan hospitals Material...
The main aims of solid waste management are to protect the environment and human health; and, to conserve natural resources. However, increasing consumption, environmental issues and resource depletion threaten its sustainability. Solid waste management policies usually fail to reduce consumption, decrease environmental impacts, conserve raw materials and develop sustainable products. These pro...
The present study was performed to investigate the effects of using chicken abattoir waste powder instead of fish powder using dietary supplement (garlic powder) in the diet of Huso huso with an average initial weight of 50.66 ± 1.5 g, on the index. Growth, carcass composition and digestibility were examined in a completely randomized design with 8 treatments, each with 3 replications for 12 we...
Many agrofood industries produce huge amount of waste in a form of biomass as a byproduct. Irregular disposal of this waste can cause a serious harm to the environment. However, such waste has received much attention as a renewable energy source. Recently, protecting the environment through a safe disposal of waste has gained much attention in order to guarantee a sustainable environment and su...
use of raman spectroscopy to decrease time for identifying the species of candida growth in cultures
background: the objective of this study is to establish raman signatures from pure cultures of different candida species using raman spectroscopy (rs) and use these signatures for rapid identification of unknown candida species. methods: pure cultures of five candida species were evaluated using rs to build a limited signature library. ‘raman processing’ (rp) software was used for principal com...
Introduction: The presence of pathogenic microbial agents and pathogens in organic fertilizers causes health problems and disease transmission. The aim of this study was to evaluate the efficiency of vermicomposting process in improve the microbial quality of the compost produced. Materials and Methods: This experimental study was conducted as a pilot-scale one, in the laboratory of school of...
post-harvest management of potatoes is a major challenge in iran. approximately 30% of the harvest is lostafter a few months of storage. the chemical methods for long term storage are not adequate to controldeterioration and also produce undesirable side effects. to address this issue, a study on radiationpreservation of potatoes was carried out. agria potato bulbs were irradiated using beta be...
