Juniper Publishers - In Vitro Toxicology, Biodetection and Risk Assessment

Image
  Trends in Technical & Scientific Research Opinion Context Food may be assumed as a complex mixture of chemicals. Some are intrinsic components, including macro-and micronutrients, anti-nutrients and inherent toxicants, while others are extrinsic, either added or resulting from natural or industrial sources. In addition, process-related chemicals are formed during processing. To understand the health significance of food chemicals is complex. Many increase but others reduce nutritional value. Some may be associated with beneficial effects. A number have been shown to be harmful, producing toxicity. Therefore, chemicals must be managed to ensure that food is safe. Risk assessment, combining exposure and toxicological information, has been valuable to identify chemicals of concern on which management efforts should focus. Toxicological characterization is a resource-intensive and time-consuming process based on feeding experimental animals with high doses of t...

Juniper Publishers - The Development Tendency of Environmental Sustainability of Domestic Enterprises and Institutions

Image
  Trends in Technical & Scientific Research Opinion In the recent centuries, the increase in the global population has led to an increase in the aggregate demand for resources, their intensive use around the world. In an unprecedented and predatory way of using natural resources around the world in the course of the last centuries, has led to an accelerated depletion of their reserves, a significant degree of their degradation and, most importantly , it led to the introduction of new and exacerbation of existing global environmental problems, such as desertification, change (warming) of climate, the disappearance of rare species of flora and fauna, etc. The aggravation of the above problems all over the world, expressed in the lack of acceptable resources for use, in a strong decline in efficiency and productivity in the frequency of a natural and climatic nature, bearing huge losses, contributed to the emergence of environmental problems and improved living standar...

Juniper Publishers - Alternative Production Processes of Calcium Silicate Phases: A Review

Image
  Trends in Technical & Scientific Research Abstract Calcium silicates production by alternative methods to solid state reaction method has gained importance because of the possibility to obtain materials with higher performance and less energy consumption than the traditional process. Exploring the application of non-conventional methods for the production of cementitious materials is an interesting alternative to produce materials with high performance, as nanoparticles, which are expected to permit high reactivity of the phases. The alternative methods require more studies allowing to understand the individually and the combine effects of synthesis processes conditions over the particles properties. Keywords: Synthesis; Alternative methods; Calcium silicates; Clinker; Portland cement; Pure cement phases Considerations Global demand of cement is increasing year by year in a factor of 25; therefore, greenhouse gas emissions from this in...

Juniper Publishers - Bioluminescence: Chemical Study on Visible Light Emission from Fungal Mycelium and Fruiting Body

Image
  Trends in Technical & Scientific Research Abstract Although the visible light emission by living organisms is generally thought to be rare, in fact the bioluminescent phenomenon can be widely observed in nature, for examples insects, fishes, bacteria, and fungi. The phenomenon has intrigued scientific researchers over the years.The chemical mechanisms underlying bioluminescence differ between species. Some mechanisms, such as bioluminescence of firefly, jellyfish, bacteria, and dinoflagellate, have been elucidated and further more their principles have allowed the development of many novel technologies in agriculture, biology, ecology, and medicine. However, many other bioluminescence mechanisms yet remain to be understood. Further research of bioluminescence will lead discoveries of biological significance and novel possibility in science. Here I present studies on chemical mechanism underlying fungal bioluminescence, which are actively in progress. Keywords: B...
