Research ArticleOpen accessIn the keywordsPerformance Assessment of Solar Chimneys: Part 2 – Impacts of Slenderness Value and Collector Slope on Power OutputErdem Cuce, Pinar Mert CuceIn the previous part, impacts of chimney height thus pressure difference on the power output of solar chimneys have been numerically evaluated. Within the scope of this research, slenderness and slope of collector are analysed in terms of their potential influence on average velocity of air at the chimney inlet. The analyses are based on a commercial and reliable CFD … …Energy Research Journal, Vol. 10, Issue 1 · 9 Jul 2019 · 6,851 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPerformance Assessment of Solar Chimneys: Part I – Impact of Chimney Height on Power OutputErdem Cuce, Pinar Mert CuceSolar chimney is a truly sustainable and green energy technology, which is a potential alternative to carbon-based energy economy. The working principle of solar chimneys is based on the buoyant nature of air to turn a turbine that produces electrical power. Solar chimneys are highly in the centre of interest among all solar energy applications since they enable both day … …Energy Research Journal, Vol. 10, Issue 1 · 29 Jun 2019 · 8,195 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimalization of the Swim-Up Method for Bali Bull Sperm: Effect of Incubation Time and Medium on Sperm KineticsAthhar Manabi Diansyah, Muhammad Yusuf, Rahmat et al.Bali bulls (Bos javanicus) are an essential part of Indonesia’s indigenous livestock, prized for their ability to thrive in challenging environments, their natural disease resistance, and their strong reproductive capabilities. The aim of this study was to refine the swim-up technique for preparing Bali cattle sperm. We evaluated the effects of two commonly used media Tyrode's Albumin Lactate Pyruvate (TALP) … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 4 · 9 Feb 2026 · 1,687 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn vitro Kinematics Semen Tolerance to Oxidative StressCyril Mpho PilaneInterpretation of semen kinematic parameters remain as a point of discussion in predicting semen quality following processes like cryopreservation. During cryopreservation, oxidative stress remains a challenge in promoting post-thaw semen quality. Comparison of livestock semen exposed to oxidative stress, in vitro, highlight various aspects of sperm cell movement, like kinematics, to predict their qualities. Sperm cell kinematics includes the measurement … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 13 Sep 2024 · 4,560 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Weathering Layer Characteristics over OPL-135 in the Western Part of the Niger Delta Basin, South-South, NigeriaOkechukwu Frank Adizua, Adekunle Oyemade Sofolabo, Olomu Ivory Obi-EgbediAn up-hole seismic refraction survey was carried out in OPL-135 in the Western part of the Niger Delta Basin, (SS) Nigeria. A total of thirty seven (37) up-hole locations in a (4.0×3.750) km grid configuration were drilled and logged over the prospect. The focal objective for the study was to assess the weathering layer characteristics over the prospect, specifically, to … …Current Research in Geoscience, Vol. 11, Issue 1 · 3 Feb 2021 · 11,449 accessesView PDFCite
Research ArticleOpen accessIn the abstractSeasonal Variations in Semen Parameters of Zulu Rams Preserved at 10°C for 72 H During Breeding and Non-Breeding SeasonJabulani Nkululeko Ngcobo, Khathutshelo Agree Nephawe, Ayanda Maqhashu, Tshimangadzo Lucky NedambaleThe study was conducted to evaluate the seasonal variations in semen parameters of Zulu rams preserved at 10°C for 72 h. The study site was the Agricultural Research Council (ARC) Irene, during the breeding season and the non-breeding season. Zulu rams (n = 6, age = 3 years and average weight = 35 kg ±2.29) were used in this study. … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 3 · 28 Aug 2020 · 7,302 accessesView PDFCite
Research ArticleOpen accessIn the abstractDOWNHOLE SEISMIC REFRACTION SURVEY OF WEATHERED LAYER CHARACTERISTICS IN ESCRAVOS, NIGERIAOchuko AnomohanranThe problem of datum correction in seismic surveys and the failures associated with civil engineering structures with specific reference to roads and buildings has been attributed to lack of understanding of the soil structure among others. This is why this survey on downhole seismic refraction was conducted from nine borehole locations in Escravos, Nigeria to determine the weathered layer characteristics … …American Journal of Applied Sciences, Vol. 11, Issue 3 · 30 Dec 2013 · 7,738 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Design of Blade for Small Horizontal-Axis Wind Turbine with Low Wind Speed OperationParamet Pathike, Thanad Katpradit, Pradit Terdtoon, Phrut SakulchangsatjataiIn Thailand, the average wind speed throughout the country is comparatively low for normally-available wind turbine. Designing of a new blade suitable for applications in the average wind speed of 3-7 m sec-1 is, thus, a main objective of this study. High torque has to be obtained properly to generate electricity. In order to design and evaluate performance, our mechanical … …Energy Research Journal, Vol. 4, Issue 1 · 26 Aug 2013 · 8,063 accessesView PDFCite
