introduction: since discovery of high frequency waves, their biological effects have been in great attention. increased male fertility problems proposed their possible relation to use of microwaves. testes are of very active body tissues, which can be affected by these waves. age of exposure may also be an important factor. methods: this study was carried out to evaluated testosterone level in ...

Sterilization is a process that eliminates or kills all microbes, including transmissible agents present on a surface, contained in a fluid, medication or biological culture media (UCLA Department Epidemiology). Dry heat sterilization is one of the important methods of eliminating microbes, as it coagulates the proteins in an organism, causing oxidative free radical damage thus leading to cell ...

Present preliminary scientific trial was designed to investigate of microwave effects on Japanese quails as an animal model. Thirty six three days-old quail chicks were randomly divided into 3 experimental groups and received: A) un-treated tap water, B) tap water boiled by electrical heater and then cooled and C) tap water treated by microwave oven and then cooled. The whole experimental perio...

A bioaccessibility test with raw and cooked lamb meat samples was performed. The evaluated cooking devices were grill, microwave oven, air fryer, pressure cooker, electric oven. Physicochemical parameters the total mass fraction of Cu, Fe, K, Mg, P, Zn determined in by inductively coupled plasma optical emission spectrometry (ICP OES). trueness using certified reference materials, recoveries fr...

Background: Drying is the most common way to preserve quality of aromatic and medicinal plants. Chosen drying methods can affect on the essential oil content and composition of medicinal plants. Objective: This study aimed to assess the changes in essential oil constitutes of catnip aerial part under various drying methods. Methods: The experiment was performed as the randomized complete ...

In this work, the effects of preparation methods such as CE oven, microwave irradiation, and ultrasound on the morphology, particle size and crystallinity of MIL-53(Fe) are firstly investigated. Furthermore, the methods are utilized to prepare Pt NPs@MIL-53(Fe). As a result, well-defined Pt NPs@MIL-53(Fe) prepared by microwave irradiation exhibits uniformed morphology, hig...

Microwave is an effective means to deliver energy to food through polymeric package materials, offering potential for developing short-time in-package sterilization and pasteurization processes. The complex physics related to microwave propagation and microwave heating require special attention to the design of process systems and development of thermal processes in compliance with regulatory r...

the substances responsible for saffron’s characteristic quality are crocins, picrocrocin, and safranal. the drying process is critical to the saffron quality as measured by levels of secondary metabolites, crocin (color and anti-tumor properties), picrocrocin (taste), and safranal (aroma). four different dehydration methods were evaluated: iranian traditional method (room temperature); dehydrat...

The influence of microwave treatment on the surface roughness, hydrophobicity, and chemical composition of galena was studied. The pure galena specimens and purified galena concentrate were used in this work. A conventional multi-modal oven (with a frequency of 2.45 GHz and a maximum power of 900 W) was used to conduct the experiments. The results obtained from the atomic-force microscopy analy...
