Research ArticleOpen accessIn the keywordsReclamation of Irrigated Lands and Improvement of the Groundwater Regime Under Vertical Drainage OperationBalzhan Amanbayeva, Raushan Dzhaisambekova, Alexander Basmanov et al.The aim of the study was to identify patterns of seasonal groundwater-level fluctuations and assess the effectiveness of vertical drainage in regulating the reclamation regime of saline lands in Kazakhstan. The methods included monitoring-well observations, calculation of seasonal amplitudes, Student’s t-test, the Mann-Whitney U test, and Pearson correlation analysis. Before the growing season, groundwater occurred at a depth of 1.5-1.7 … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 23 Sep 2026 · 608 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalysis of Eco friendly Refrigerants Usage in Air-ConditionerC. Chinnaraj, R. Vijayan, P. GovindarajanProblem statement: There are two types of global warming contributions through refrigeration and air conditioning systems. The first one is the Direct Global Warming Potential (DGWP) due to the emission of refrigerants and their interaction with heat radiation. The second one is the Indirect Global Warming Potential (IDGWP) due to the emission of Carbon Dioxide (CO2) by consuming the energy … …American Journal of Environmental Sciences, Vol. 7, Issue 6 · 27 Dec 2011 · 8,462 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEfficacy of Feeding Earthworm Meal-Based Diet on Feed Intake, Weight Gain, and Apparent Digestibility Coefficient of Red Sokoto GoatMoshood Adewale Belewu et al.Feed which contributes about 70-80% of the cost of feeding is one of the major problems of livestock production. Feeding nutritious feed to animals is vital for the vigor and wellbeing of livestock and human being and the nutrient it contains assist animal to grow, develop and reproduce. Hence, this study examined the impact of Earthworm Meal (EWM)-based diets on … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 22 Mar 2025 · 4,498 accessesView PDFCite
Research ArticleOpen accessIn the keywordsStructural Dynamics of the Distribution Mechanism with Rocking Tappet with RollFlorian Ion T. Petrescu, John Kaiser Calautit, Dragan MarinkovicIn this study, the authors present a new method to dynamically synthesize a mechanism with rotary cam and rotated tappet with roll, used with priority at the distribution mechanisms from the heat engines with internal combustion. This type of distribution can improve the changes of gases and may decrease significantly the level of vibration, noises and emissions. As long as … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 28 Oct 2015 · 9,290 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Dynamic Model for GearsAversa Raffaella, Relly Victoria V. Petrescu, Antonio Apicella, Florian Ion T. PetrescuNearly all models studying the dynamic of gearing with parallel axes are based on classical mechanical models and known which are studying the spinning vibration of shafts gears and determine their own beats and strains of shafts spinning. These classical dynamic models are very useful, but they didn't take in consideration the dynamic events formed between the two teeth in … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 10 May 2017 · 7,644 accessesView PDFCite
