On Similarity of Pressure Head and Bubble Pressure Fractal Dimensions for Characterizing Permo-Carboniferous Shajara Formation, Saudi Arabia

Pressure head was gained from the distribution of pores to characterize the sandstones of the Shajara reservoirs of the permo-Carboniferous Shajara Formation. The attained values of pressure head were employed to calculate the pressure head fractal dimension. Based on field observations in addition to the acquired values of the pressure head fractal dimension, the sandstones of Shajara reservoirs were divided here into three units. The obtained units from base to top are: Lower Shajara Pressure Head Fractal Dimension Unit, Middle Shajara Pressure Head Fractal Dimension Unit and Upper Shajara Pressure Head Fractal Dimension Unit.

Efficacy of Purified Glutathione -S- Transferee in Providing Protection against Haemonchus Contortus Infection in Sheep

The efficacy of purified glutathione-s-transferase (GST) to protect sheep against haemonchosis was assessed. Fifteen lambs, 3.5-5month-old, were bisected into five groups (n=3). Two groups were vaccinated with 250μg of each prepared antigen (crude adult antigen (CAA), purified GST) in combination with mineral oil adjuvant at zero, 14th days of the experiment. The other three groups were kept as control groups; non-immunized infected, non-immunized non-infected and adjuvant control. One week after the last booster dose, the lambs in all groups except control negative were challenged with 400 L3/kg live weight orally. Protein characterization of each antigen was done by SDS-PAGE and immunoblting. The vaccine efficacy was estimated by the fecal egg count, where the vaccinated groups showed 58.90% and 79.38% reduction in eggs in CAA and GST respectively. Moreover, 31.45% and 92.10% reduction in abomasal worm count was reported in CAA and GST vaccinated lambs, respectively. The protection was found corresponsive to the sera antibody levels in the immunized groups. It was concluded that the GST had protective efficacy against H. contortus infection in lambs.

Potential of Producing Hydrogen Gas from Straw by Anaerobic Thermal Shocked Biological Sludge to Create Clean Energy

Hydrogen gas has been used widely in the industrial aspect, especially as clean energy. On one hand, it reduces the dependency on fossil fuels; on the other hand, it solves the environmental polluting issue and also reduces the greenhouse gases emitted to the environment. Producing hydrogen by chemical and physical methods require higher fee and investment. Producing hydrogen from renewable biomass, especially agricultural waste such as straws, can produce with low cost and decrease the amount of agricultural waste and pollutions. This article introduces the result of the beginning research to produce hydrogen gas from straw using biotechnology.

Prevalence of Mastitis and Associated risk factors in Jimma Town Dairy Farms, Western Ethiopia

Across sectional study of epidemiological risk factors and associated bacterial pathogens was conducted on 216 lactating dairy cows in jimma town from Oct. 2016 to April 2017 to determine the overall prevalence rate, associated bacterial pathogens and to assess effect of risk factors on prevalence of mastitis. Upon physical examination of udder and teats the prevalence of clinical mastitis was 2.3% at cow level and 0.96% at quarter level. Using the California mastitis test (CMT) for detection of sub clinical mastitis, the prevalence of sub clinical mastitis at cow level and quarter level was 60.65 and 38.4% respectively. The overall prevalence of mastitis was 62.96. Out of 323 (38.4%) CMT positive quarters with evidence of sub clinical mastitis, the quarter infection rate for the right rare quarter was highest (41.3%) followed by left rear (38.8%), right and left front (each 36.7%). Up on microbiological examination of milk samples for both clinical and subclinical quarters, out of a total of 331 cultured, 271(81.9%) yielded bacteria whereas 60(18.1%) yielded no bacteria. A total of 263 bacterial pathogens were isolated whereas 8 were mixed infections with more than two different colonies. The main bacterial pathogens isolated were coagulase negative staphylococci (CNS) (26.6 %), Staphylococcus aureus (24.7%), Escherichia coli (13.31%), Streptococcus species (9.13%), and Pseudomonas aeruginosa (8.8%). Other bacteria isolated with low isolation rate were micrococcus species (3.04%), Corynebacterium species (3.4%), Actinomyces pyogenes (3.8%), Bacillus species (3.42%) and other gram negative rods (3.8%). Host factors such as breed, age parity and lactation stage had significant effect on the prevalence of mastitis (p‹0.05). Managemental and environmental factors such as bedding, ventilation, frequency of barn cleaning, udder washing and use of communal towel had significant effect on the occurrence of mastitis (p‹0.05). Whereas milking practice, drainage had insignificant effect on the prevalence of mastitis (p›0.05).

Ordered Growth of Anodic Aluminum Oxide in Galvanostatic and Galvanostatic-Potentiostatic Modes

The results are presented of obtaining anodic aluminum oxide with an ordered pore arrangement by employing two anodizing modes - galvanostatic mode and combined (galvanostatic + potentiostatic) mode, at high values of the current density and voltage. Use has been made of an oxalate electrolyte and a complex electrolyte comprising oxalic acid and phosphoric acid. Scanning electron microscopy has been used to investigate the surface morphology of the barrier and porous layers and to determine pore sizes and inter-pore distance.

Anodizing for Design and Function

Two basic reactions occur during the anodizing of aluminum: 1) the aluminum is consumed and 2) an oxide grows. By accepting this statement as true, the anodizing process can be viewed as a corrosion process, and anodizing can be modeled using the Tafel Equation. Anodizing process parameters of electrolyte chemistry and concentration, temperature, aluminum substrate resistance and current density are presented as they relate to the Tafel Equation and how they impact the anodic aluminum oxide structure and properties. Understanding this relationship is consequent in making anodizing an engineering process, one that enables tuning the structure such that it yields distinct characteristics to fulfill design and application requirements.

Electronic-nose Applications in Forensic Science and for Analysis of Volatile Biomarkers in the Human Breath

The application of electronic-nose (E-nose) technologies in forensic science is a recent new development following a long history of progress in the development of diverse applications in the related biomedical and pharmaceutical fields. Data from forensic analyses must satisfy the needs and requirements of both the scientific and legal communities. The type of data collected from electronic-nose devices provides a means of identifying specific types of information about the chemical nature of evidentiary objects and samples under investigation using aroma signature profiles of complex gaseous mixtures containing volatile organic compounds (VOCs) released from manufactured products and parts of the human body. E-nose analyses also provide useful qualitative information about the physicochemical characteristics and metabolic conditions of human subjects without the need for time-consuming analyses to identify all chemical components in human-derived volatile mixtures.

The Effects of the Film Thickness and Roughness in the Anodization Process of Very Thin Aluminum Films

The anodization of aluminum foils having micrometer thickness is a common process and results in hexagonally self-ordered alumina membranes. However, anodic aluminum oxide (AAO) membranes fabricated from nanometer-thin films present new challenges to the anodization process, since aluminum films adheres poorly on supporting substrates and the smoothness of the film is highly related to the kind of substrate.

Synthesis of BaTiO3 Nanowires via Anodic Aluminum Oxide Template Method Assisted by Vacuum-and-Drop Loading

In this paper, we report on the synthesis of BaTiO3 nanowires via the anodic aluminum oxide template method. To fill in the precursors of BaTiO3 into anodic aluminum oxide templates, the vacuum and drop loading method developed in our previous study was used. Ba(CH3COO)2 (barium acetate) and C12H28O4Ti (tetraisopropyl orthotitanate) were used as Ba and Ti sources, respectively. Anodic aluminum oxide membranes with the through-hole diameter of ~200 nm were used as the template for BaTiO3 nanowires.
