Research ArticleOpen accessIn the abstractStudy on the Suitable Irrigation Amount of Microporous Membrane Water-Fertilizer Integration of Tomato in Spring in Plastic GreenhouseXiao Huaijuan, Du Qingjie, Zhang Jiaxin et al.Water-saving irrigation is an important measure to alleviate the shortage of water resources in China. In this study, the growth, nutrient distribution, quality and yield of Tomato under different irrigation treatments are studied by using microporous membrane water-fertilizer integrated technology and the optimal irrigation water quantity under the condition of microporous membrane water-fertilizer integration was determined. The results show that … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 2 · 15 Jun 2020 · 7,403 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImpact of Chemical Coagulants for Oscillatoria sp. Removal from Raw Water on Chemical Coagulation ProcessSaowapak Thammasane, Thaniya KaosolGrowing Oscillatoria sp. in freshwater causes several poisoning episodes of domestic livestock animal and human. The chemical coagulation of raw water using chemical coagulants is very simple and requiring less investment cost on equipment. These experiments used alum and PACl (Polyaluminium chloride) with alum as chemical coagulants for Oscillatoria sp. removal. The Oscillatoria sp. was prepared from Molecular and Cell … …American Journal of Environmental Sciences, Vol. 14, Issue 6 · 14 Dec 2018 · 8,610 accessesView PDF Cite

Research ArticleOpen accessIn the abstractContributions to the Stirling Engine StudyFlorian Ion Tiberiu PetrescuIn the process of transforming thermal energy into mechanical work, among the known thermal machines, the Stirling engine is the one that can achieve the highest yield (theoretically up to the maximum yield of the Carnot cycle), although in practice it is reduced by the properties of gas and materials used such as friction coefficient, thermal conductivity, melting point, breaking … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 22 Nov 2018 · 10,172 accessesView PDF Cite

InvestigationOpen accessIn the abstractEvaluation of Black Currant Cultivars Resistance to Aphis grossulariae Kalt. and Effectiveness of Water Extracts of Artemisia Absinthium L. and Tanacetum Vulgare L. Against this PestNatalya Gennadievna Andrianova, Tatyana Vladimirovna Likhacheva, Tatyana Olegovna SirotinaThis study consisted in revealing the possibility of using two ecologically safe methods to control gooseberry aphid (Aphis grossulariae Kalt.) in black currant cultivars: selection aphid resistant cultivars and the use of plant water extracts of wormwood (Artemisia absinthium L.) and tansy (Tanacetum vulgare L.) in the arid zone of Central Kazakhstan for protection against aphid. The study of the … …OnLine Journal of Biological Sciences, Vol. 18, Issue 1 · 26 Mar 2018 · 7,391 accessesView PDF Cite

InvestigationOpen accessIn the abstractComparative Ameliorative Efficiency of Phosphogypsum and Elemental Sulfur in Semi-Terrestrial Soda and Sulfate Moderately Halophytic Solonetz of the Light Gray Earth SubzoneKanaibek Kubenkulov, Nurzhamal Khokhanbaeva, Askhat NaushabayevThe article presents the data from field tests on determination of the relative ameliorative efficiency of equivalent dosages of phosphogypsum and elemental sulfur on the alkaline saline semi-terrestrialsolonetz. Basing on the analysis data of soil water extract, higher ameliorative efficiency of elemental sulfur compared to phosphogypsum and fast amelioration of alkali-saline soils with the use of sulfur have been detected. … …OnLine Journal of Biological Sciences, Vol. 18, Issue 2 · 6 Feb 2018 · 7,421 accessesView PDF Cite

Research ArticleOpen accessIn the abstractModern Propulsions for Aerospace-Part IIRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.Speaking about a new engine ionic means to speak about a new aircraft. The paper presents in a short time the actual engines ion chambers (called the ion thrusters) and other new ionic motors proposed by the authors. The engine (ionic propulsion unit of ions, that accelerates the positive ions through a potential difference) is approximately ten times more efficient … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 1 · 25 Apr 2017 · 8,118 accessesView PDF Cite

EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,521 accessesView PDF Cite

Review ArticleOpen accessIn the abstractCorrelation of Biodiversity of Algal Genera with Special Reference to the Waste Water Effluents from IndustriesRitu Singh Rajput, Sonali Pandey, Seema BhadauriaPollution is the introduction of contaminants, which cause adverse change, into the natural environment and mainly from external inputs like sewage, waste from industries, oil spills and agricultural use of pesticides. Anthropogenic activity-reflected in the use of toxic metals and organic pollutants-has increased levels of soil contamination and damage to aquatic systems. Ecosystems maintain water quality and withstand pressure from … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 9 Dec 2016 · 8,608 accessesView PDF Cite

EditorialOpen accessIn the abstractProtecting crop species from biotic and abiotic constraints in the era of Global Change: are we ready for this challenge?Marco Landi, Giovanni BenelliReliable and affordable supply of food is of crucial importance to the progress and stability of human societies. During the last century, we have assisted to an extraordinary increase of crop yields, especially for the most widespread and consumed crop species, such as rice, wheat, corn and soybean. The Broadbalk experiment, one of the oldest continuous agronomic experiments in the … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 2 · 4 Jun 2016 · 8,399 accessesView PDF Cite
