Abstract: The aim of the study was to observe parasitic effect on lipase and glucose content in the tissue of artificially infested host pigeon with cestode parasites. Gastro-intestinal tract associated organs were extracted from the body cavity of dissected animal. Gizzard, liver, spleen, pancreas were separated and preserved. Thereafter, Lipase and glucose determination was carried out from these organs.

It was observed that parasitic infection decreased lipase in liver and spleen while increased in pancreas. Higher lipase content was measured in infected animal’s crop a lesser content was measured in gizzard. It was also observed that infection impaired glucose level in intestine and other organs as well. Parasitic infections enhanced the glucose level in intestine and crop, while decreased glucose level in spleen, pancreas and liver.

Keywords: Parasitic Infection effects, Glucose, Lipase, Pigeon Columba livia.

The Effect of Grain Size on Radon Exhalation Rate in Soil Samples of Dera Ismail Khan in Pakistan

Tabassum Nasir and Nisar Ahmad

http://dx.doi.org/10.6000/1927-5129.2012.08.02.29

Abstract: Radon concentration and its exhalation rate has been measured from twenty five soil samples collected from seven different locations of Dera Ismail Khan, in the north west of Pakistan. These samples were crushed after drying and passed through sieves with different sizes of pores to get three grain sizes, £0.595 mm, 0.595-2.00 mm and 2.00-4.00 mm of soil. CR-39 based NRPB (National Radiological Protection Board) radon dosimeters have been used to measure the radon concentration and exhalation rates. The maximum average value of radon exhalation rate has found to be: (3.57±0.38) Bq m-2 hr-1 in the samples having grain size 2.00-4.00 mm and the minimum as: (2.21±0.26) Bq m-2 hr-1, in the samples with grain size £ 0.0595 mm. This indicates that the radon exhalation rate increases with the grain size. The maximum average value of radon exhalation rate has been found in samples collected from river side where soil texture is silty clay loam. The obtained values of radon exhalation rate for all the samples are well below the world average value of 57.60 Bq m-2 hr-1.

Keywords: Radon concentration, Radon exhalation rate, grain size, soil texture.

http://dx.doi.org/10.6000/1927-5129.2012.08.02.38

Abstract: The effect of gamma radiation source (Cs137) on the aqueous solutions of the Sandalfix Golden Yellow CRL dye was determined in the range 0-1kGy. λmax of the dye was determined by UV/VIS spectrophotometer before the exposure of gamma radiations and was found to be 422 nm. Absorbance of the sample solutions was studied at λmax of the dye at pre and post irradiation. It was determined that the Absorbance of the sample solutions was decreased with increasing absorbed dose. The exposed dye solutions were found to be discolored due to the structural changes in the dye solutions and the discoloration of the dye was found linear with respect to absorbed dose.

Keywords: Sandalfix Golden Yellow CRL, dosimetry, Cs137 gamma source, radiolytic bleaching.

Radiolytic Reduction of Aqueous Solutions of a Commercial Reactive Dye in the Range 0-100KGY by CO60 Gamma Radiation Source

Taqmeem Hussain, Muhammad Shahbaz, Inam-ul-Haq and Hashim Farooq

http://dx.doi.org/10.6000/1927-5129.2012.08.02.04

Abstract: Gamma dosimetric behavior of the aqueous solutions of the Sandalfix Golden Yellow CRL (SGY-145) dye was studied. The sample solutions of two chemical natures i.e., Acidic and Alkaline; were irradiated by Co60 γ-sources in the range 0-100kGy. The “Control samples” were remained un-irradiated and also chemically neutral. The dosimetry was done in three phases i.e., Low, Intermediate and High, ranging from 100-1000Gy, 1-10kGy and 10-100kGy respectively. The found values of the “λmax” and the molar extinction coefficient “ε” of the dye were 467 nm and 3.4×103 mol-1cm-1 respectively. The absorbance (A) of the aqueous solutions was studied at the absorption band maxima (λmax). The behavior of “Alkaline and Acidic solutions” was checked with the help of curve fitting.

Keywords: Chemical dosimeters, Sandalfix Golden Yellow CRL dye, dosimetry, optical density (OD), radiolytic bleaching.

Some New Exact Solutions for Prescribed Vorticity Distribution of Couple Stress Fluids in the Presence of Unknown Body Force

Rana Khalid Naeem

http://dx.doi.org/10.6000/1927-5129.2012.08.02.39

Abstract: In the present paper, we indicate some new exact solutions of equations of motion for plane steady incompressible couple stress fluids flows in the presence of unknown body force for which vorticity distribution is defined by Eq. (12). All solutions involve arbitrary real constants and arbitrary real constants depending on the parameter è indicating that a large number of streamfunctions and expressions for body force can be constructed. Some streamfunctions ø are constructed for some values of parameters. The streamlines patterns of these streamfunctions are presented and discussed.

Keywords: Exact solutions, Couple stress fluid, Flows for prescribed vorticity distribution.

Abstract: Normal haematopoiesis, cellular components and M/E ratio in the bone marrow of the male adult ostriches (Struthio camelus) were studied. Bone marrow samples were collected from the proximal tibiotarsus bone of 10 healthy adult ostriches. The bone marrow smears were stained using the Giemsa stain. The results indicated that the development and formation of blood cells in the bone marrow of partridge were similar to other birds. The morphology of the cells was similar to chickens, ducks, quail, and black-head gull. The mean myeloid/erythroid (M/E) ratio was 1.02, the mean erythroid percentage was 47.38%, the mean myeloid percentage was 48.15%, the mean thrombocytic percentage was 3.52% and the mean percentage of all other cells percentage was 0.99%.

Keywords: Bone marrow, Haematopoietic cells morphology, M/E ratio, Ostrich.
