in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
Good manufacturing practice (GMP) is applied to the manufacture of immunological veterinary medicinal products (IVMPs) in a number of regions around the world. Within the European Union (EU) there are well-established requirements for GMP in the manufacture of IVMPs. Maintaining GMP when producing IVMPs is important because there are particular risks associated with their manufacture. These ris...
دسته ای از ترکیبات شیمیائی که مخصوصا با گسترش زندگانی جدید (ماشینی)اهمیت فرآینده ای پیدامی کنند، افزودنیهای مختلف غذائی میباشند که در صنایع مربوطه بکار گرفته می شوند بکارگیری بخشی از این موا تحت عنوان طعم دهنده ها بمنظور تامین طعم و مزه طبیعی درفرآورده های صنعتی تقریبا اجتناب ناپذیر گشته و همگام با توسعه تولیدات روبه توسعه می رود. یک شناخت سیستماتیک و جامع از خواص و آثار اینگونه مواد طبیعتا مست...

Methods We undertoo...
This investigation provides an updated survey measuring the levels of N'-nitrosonornicotine (NNN) and water content of a select number of smokeless tobacco products sold in the United States in 2015. A total of 34 smokeless tobacco products were collected and analyzed for NNN and water content using LC-MS/MS and GC-TCD, respectively. Smokeless tobacco products were chosen to obtain a representa...
BACKGROUND Noncigarette tobacco products are increasingly popular among youth, especially cigarette smokers. Understanding multiple tobacco product use is necessary to assess the effects of tobacco products on population health. This study examines multiple tobacco product use and associated risk factors among US youth. METHODS Estimates of current use were calculated for cigarettes, cigars, ...
The results available so far suggest to us the following tentative conclusions. First, there are at least two agents extracted by aqueous barium hydroxide from commercial cigarette tobacco that are required simultaneously in order to exhibit tumor-promoting activity. One of the agents is soluble in 80% methanol and is probably soluble in 95% methanol. The other is insoluble in 80% methanol and ...
background: it is suggested that various forms of tobacco use have some effects on diverse sites of head and neck to develop cancer. material and methods: the study examines data for oral cancer in male subjects, collected from the population registered in cancer registry during the year 2007- 2008. all the data collected were entered into the spreadsheets. the statistical package for social sc...
