nanoclay/triphenyl phosphate hybrid system was employed to examine the fire retardancy and mechanical properties of pc/abs blends. each of the polymers and their blends are widely used in the automotive, electrical andelectronic industries. because most thermoplastics are easily combustible they need to be flame retarded to reduce the burning rate especially in the initial phase of a fire incid...

Fire can influence the stability of many natural habitats via changes in biological, chemical and physical properties of soil. The aim of the present study was to investigate the effects of fire on some chemical properties and nutrients availability in a rangeland soil. To perform this research, a fired area with a five-month history and a homogenized area close to it without fire were selected...

There is a large demand for fabrics that can survive high-temperature fires for an extended period of time, and protect the skin from burn injuries. Even though fire-resistant polymer fabrics are commercially available, many of these fabrics are expensive, decompose rapidly, and/or become very hot when exposed to high temperatures. We have developed a new class of fire-retarding materials by la...

Background & Objectives : It is not possible to live without using fire. However, fire could destruct human properties in a short time. One of the most important types of fire is intentional fire. This type of fire has become a great problem for insurance companies, fire departments, industries, government and business in the recent years. This study aimed to provide a framework for risk assess...

Forest fire is the major disturbance that can severely destruct genetic stocks and delays evolution of the forest to reach the climax stage. In this research, the effect of fire, vegetation and soil changes from 2002 to 2013 have studied. Following the steps of determining the scope of fire using GPS, preparing a homogeneous unit map in ArcMap software and implementing a systematic random-acces...

The operation of flood retarding areas does not attract much attention, although they are important components of flood control systems. Poor operation of such areas restricts not only the socio-economic development of the flood retarding area, but also limits scientific flood control options. As the second-largest flood retarding area in China, with more than 2000 km2 and 300 polders, the Hong...

Triphenyl phosphate (TPP) is a triester of phosphoric acid and phenol. It is commonly used as a fire-retarding agent and plasticizer for nitrocellulose and cellulose acetate. The present study was an attempt to evaluate the impact of biofield treatment on physicochemical and spectroscopic properties of TPP. The study was carried out in two groups i.e. control and treatment. The treatment group ...

Rebecca Turner Late Quaternary fire histories in the Eastern Mediterranean region from lake sedimentary micro-charcoals. The Eastern Mediterranean has a long history of human occupation, which spans the transition from hunter-gatherers to the establishment of early agro-pastoralist communities, coinciding with the Last Glacial: Interglacial transition. Over the same timeframe a delay in postgla...
