Research NotesOpen accessIn the abstractA Study on Fabrication and Structural Characterization of PbS Thin FilmsMustika Wati, Kamsul AbrahaPbS thin films are fabricated from 99.9% PbS powder on glass substrates using the vacuum evaporation method. Some of the samples are then treated in an advanced process called annealing. Samples are annealed in temperatures of 80, 100, 120 and 150°C for two h. Characterization using an X-Ray Diffractometer (XRD) resulted in values of lattice constant of the films ranging … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 20 Nov 2017 · 7,847 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHistomorphochemical Studies on Accessory Glands of Iraqi Blackbuck (Caprus Hircus)Waleed J. A. Al-Kelaby, Wafaa Hadi Mousa AL-Hashem, Zahraa S. M. Al Kaabi et al.Thevarious species' male accessory genital glands vary and are intimately relatedto the pelvic urethra. These glands secrete nutritional substances, buffers,and mucous to increase volume, serve as lubricants, reduce the minor acidity ofvaginal contents and make the environment more hospitable to motile sperm. Thisstudy aims to study the histological and histochemical structure of the maleaccessory sex glands in caprine Iraqi breeds. … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 4 · 25 Nov 2022 · 5,382 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHighly-Efficient Advanced Thermoelectric Devices from Different Multilayer Thin FilmsSatilmis Budak, Zhigang Xiao, Barry Johnson et al.The efficiency of the thermoelectric materials and devices is shown by the dimensionless Figure of merit, ZT. ZT is calculated by multiplying the Seebeck coefficient with square of the electrical conductivity and absolute temperature and dividing it all by the thermal conductivity. Thermoelectric devices were prepared using different multilayered thin film structures in the order of SiO2/SiO2 + Ge/Ge/Sb + … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 27 Apr 2016 · 8,368 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDirect Shocks in Vibrationally Nonequilibrium Diatomic Gases at Various Distances from Critical Cross-Section of NozzleRydalevskaya Maria Alexandrovna, Voroshilova Yulia Nikolaevna, Uskov Vladimir NikolaevichThe high-temperature diatomic gas flows are considered in expanding nozzles under the conditions of a disturbance of the equilibrium distribution over vibrational levels of the molecules. The investigation of such flows is bound up with the problem of the inversion of the vibrational populations in the active mediums of molecular lasers. Under diverse values of the pressure overfall on coming … …American Journal of Applied Sciences, Vol. 11, Issue 11 · 7 Jan 2015 · 6,651 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAdvantages of Utilizing Geotextiles in Fixing Sandy Soils and Increasing Shear Strength in Water Conveyance TrenchesAlireza Mardookhpour, Leila OoshaksaraieWith the increasing demand in water supply and either for generation or for irrigation and human consumption, water conveyance structures must guarantee a maximum efficiency at the lowest construction and maintenance costs. Using thin geotextiles allow very low permeability and very high transmissivity. Conclusion/Recommendations: The system constructs a continues, low roughness on the entire section of canal. In this research … …Current Research in Geoscience, Vol. 2, Issue 1 · 23 Jan 2012 · 13,184 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStructure of Lamellae and Chloride Cell in the Gill of Alosa Caspio Caspio (Clupeidae, Teleostei)Z. Saadatfar, D. ShahsavaniAs a surface for respiratory gas diffusion, ion regulation and waste excretion, gill epithelium of Alosa Caspio Caspio has been investigated. Problem statement: Surely, morphological study of gill cells is the main route for giving the basic data which can be inductive for physiological and pathological investigations. Approach: Gills were removed from Alosa Caspio which is from euryhaline species and … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 6,881 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFeasibility of Using TIG Welding in Dissimilar Metals between Steel/Aluminum AlloyRattana Borrisutthekul, Pusit Mitsomwang, Sirirat Rattanachan, Yoshiharu MutohProblem statement: Currently, in order to suppress intermetallic reaction layer formation during dissimilar metals welding between steel/aluminum alloy, only laser beam welding as self-brazing technique has been applied. However, TIG welding process might be one of welding process candidate for joining dissimilar metals welding between steel/aluminum alloys due to its capability in joining thin section. In the present study, the … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 14,513 accessesView PDF Cite
