BACKGROUND To identify adverse pulmonary health effects due to air pollution derived from a cement plant in Korea. The emphysema prevalence in residents around a cement plant was compared to that in the group who live far away from the plant by chest films (PA and lateral view) and high-resolution computed tomography (HRCT) lung images. METHODS From June to August in 2013 and from August to N...

Exposure to cement dust has been associated with deleterious health effects in humans. This study investigated whether residing near a cement factory increases the risk of irritations to the mucous membranes of the eyes and respiratory system. A cross sectional study was conducted in Freedom Compound, a community bordering a cement factory in Chilanga, Zambia and a control community, Bauleni, l...

There is substantial diversity in Achillea biebersteinii plants in Iran. It has considerable different biological activities including antibacterial, antifungal, antioxidant, insecticidal, herbicidal and wound healing. Research improvement for medicinal plants depends on the available genetic diversity. The assessment of genetic variability could increase the information for breeding programs. ...

Air pollution has assumed a mammoth proportion in recent times because of causation of health hazards and loss of economic productivity of crop plants. The present study was carried out to assess the impact of cement klin dust pollution on some selected legume crops viz. Arachis hypogaea, Vigna mungo, V. radiate, Dolichos lablab and Cajanus cajan which are grown around the cement industry. Effe...

Particle size soft sensing in cement mills will be largely helpful in maintaining desired cement fineness or Blaine. Despite the growing use of vertical roller mills (VRM) for clinker grinding, very few research work is available on VRM modeling. This article reports the design of three types of feed forward neural network models and least square support vector regression (LS-SVR) model of a VR...

The fate of mercury (Hg) in cement processing and products has drawn intense attention due to its contribution to the ambient emission inventory. Feeding Hg-loaded coal fly ash to the cement kiln introduces additional Hg into the kiln's baghouse filter dust (BFD), and the practice of replacing 5% of cement with the Hg-loaded BFD by cement plants has recently raised environmental and occupationa...

in study was conducted in two separate experiments in 2011-2013 in seeds and plant improvement institute. in the first experiment, status growth scion and resistance to spring late frost and content proline in 10 genotypes and cultivar almond, grafted on gf677 rootstock included touno, non pariel, shokofeh, sahand, mamayi, shahrood 12, a200, 1-25, 1-16 and 13-40 with 10 replication as a complet...

ED WHELESS Whittier, California The Commerce Refuse to Energy Facility (CREF) is a nominal 370 tpd mass fired facility located in Com­ merce, California. After extensive testing of the ash, over 4 years of plant operation, a treatment system was developed and pilot tested which utilizes Portland cement to control the leaching of heavy metals. This paper describes the design and operation of the...

BACKGROUND To identify adverse renal effects due to air pollution derived from a cement plant in Korea. Urinary n-acetyl-B-glucosaminidase (U-NAG) levels in residents living near a cement plant were compared to those in a group who lived farther away from the plant. METHODS From June to August 2013 and from August to November 2014, laboratory tests for U-NAG and heavy metal were conducted on ...
