heavily polluted wastewater from sanitary landfill presents the leachate characteristics that need special treatment and disposal. concentration of chemical oxygen demand (cod), ammonia nitrogen (nh3-n), heavy metal and other pollutant content are often larger than standard requirement after applying biological/physico-chemical treatment.thus, the combination of coagulationflocculation and chem...

Low temperature molten salts have variety of applications in organic synthesis, catalytic processing, batteries and electrode position due to their air and water stability. They have wide potential window for their applications in voltage and temperature and hence there is a possibility to deposit metals which could not be deposited from aqueous electrolytes. Our aim and scope of our research w...

The microstructure of alumina ceramics based on powders with a varying grain size has been investigated. Both commercial alumina powders and those fabricated by denitration of aluminum salts in high-frequency discharge plasma were used. It is shown that the variation of the sintering temperature and morphology of the initial powders of the particles leads to a change of the pore structure of ce...

The vaccination of pigs with inactivated antigen requires adjuvanted vaccines. In general, two kinds of adjuvant are used to enhance the immunogenic properties of an antigen: aluminium salts or oil-based formulas [1, 9]. Aluminium salts often fail to induce a long-term response or a cellular immune response [7]. Emulsified vaccines are frequently used in pigs as they induce a long-lasting immun...

The entity 'sick building syndrome' is poorly defined and comprises of a set of symptoms resulting from environmental exposure to a work or a living environment. The symptoms are mainly "allergic"-like and include nasal, eye, and mucous membrane irritation, dry skin as well as respiratory symptoms and general symptoms such as fatigue, lethargy, headaches and fever. The Autoimmune [Auto-inflamma...

Breast cancer incidence suggests a lifestyle cause. A lifestyle factor used near the breast is the application of antiperspirants/deodorants accompanied by axillary shaving. A previous study did not support a link with breast cancer. If these habits have a role in breast cancer development, women using antiperspirants/deodorants and shaving their underarms frequently would be expected to have a...

The design of three stormwater treatment facilities, aiming at implementing and demonstrating technologies that efficiently reduce diffuse urban pollutant loads onto receiving waters is presented. The designs aim at reducing not only particulates, but also dissolved pollutants and pollutants associated with colloids. Unit operations that are efficient in this respect are discussed. Different te...

Chitosan, a deacetylated derivative of chitin, is a biodegradable cationic polymer. Chitosan can be a potential substitute for aluminum salts and synthetic polyelectrolytes in water treatment because it can: (1) avoid the health effects from residual aluminum (III) and synthetic polymers; (2) produce biodegradable sludge; and (3) reuse the crab shell. Chitosan can be modified with various pretr...
