Gut contents of 500 freshly slaughtered small ruminants (300 goats and 200 sheep) were studied using floatation and sedimentation methods followed by direct microscopic examination aims to investigate the prevalence of gastrointestinal tract helminthes in small ruminants of district Kohat, Khyber Pakhtunkhwa Pakistan during March-November 2013. Overall, 45.6% samples were found positive for hel...

Dengue virus (DENV) is an important human pathogen causing millions of disease cases and thousands of deaths worldwide. Non-structural protein 4A (NS4A) is a vital component of the viral replication complex (RC) and plays a major role in the formation of host cell membrane-derived structures that provide a scaffold for replication. The N-terminal cytoplasmic region of NS4A(1-48) is known to pre...

This investigation was carried out to determine the prevalence of Eimeria infections and the diversity of Eimeria species in camels of Tabriz region. The prevalence of Eimeria spp. infection and the intensity of faecal oocysts were determined in 164 camels using floatation and sporulation techniques. Faeces of 34 camels (20.73%) were infected with four Eimeria species including E. bactriani (52...

One hundred and five (105) Camels were investigated at the Maiduguri abattoir, Nigeria using floatation and sedimentation techniques for helminth parasites and haematological indices with the microhaematocrit reader. Overall, prevalence of infection was 92.4% [(Coccidia (8.5%), Strongyloides (8.5%), Trichuris (11.4%), Ciliates (6.7%), Ascaris sp. (3.8%), Moniezia sp. (1.9%), Amphistome sp. (0.9...

Black yeast fungi play critical role in degradation of petroleum polluted soils. Little attention has been paid to the biodiversity of black yeast fungi in Iran. In this paper, diversity of black yeast fungi was studied in petroleum polluted soils in Tabriz and Urmia regions. Soil samples were collected from petroleum polluted areas in vicinity of oil storage tanks in Tabriz and Urmia cities (E...

A novel and sensitive floatation-spectrophotometric method is presented for determination of trace amounts of thorium in water samples. The method is based on the ion-associated formation between thorium, Eriochrome cyanine R and Brij-35 at pH = 4 media. The complex was floated in the interface of the aqueous phase and n-hexane by vigorous shaking. After removing the aqueous phase the floated p...

The nitrogen behavior of superalloy melt GH4169 during the vacuum induction melting (VIM) process was clarified by using different proportions returned materials including block-shaped material, chip-shaped and pure to produce a high–purity provide guidance for purification melt. For removal VIM process, denitrification rate in refining period reached 10 ppm per hour on average, which is signif...

The treatment of water from paint spray booths in automobile assembly plants typically involves applications of large quantity of chemicals as coagulants and flocculants. Suspended paint solids are brought to water surface in sludge pits after these chemicals are added. The suspended paint particles are then mechanically collected and removed as sludge for further treatment and disposal. There ...
