Research ArticleOpen accessIn the abstractInfluence of Orthodontic Movement by Bracketless Orthodontic Treatment on Stress Distribution: 3D Finite Element AnalysisGuaracy Lyra da Fonseca Junior, Ney Tavares Lima Neto, Evelyne Pedroza de Andrade et al.The Bracketless Orthodontic Treatment (BOT) is an alternative technique with the concept of installing an orthodontic appliance composed only of wires and composite resin with the aid of 3D technology. However, the biomechanical behavior of this therapeutic modality has yet to be elucidated in the scientific literature. Thus, the objective of this study was to evaluate the stress distribution in … …Current Research in Dentistry, Vol. 12, Issue 1 · 4 Jul 2021 · 11,617 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Some Environmental Stresses on Bio Indicators and Population Densities of Glomus mossae Fungi Associated with Wheat (Triticum aestivum L.) CropAli Jabbar Abdulsada, Sadeq J.H. Dwenee, Naeem Saeed Dheyab et al.Field experiment was conducted to determine the effect of soil salinity and Fusariume germanium on population of Glomus mossae Fungi within root of wheat as manifested by the fungal spore’s number, density infection and the percentage of infected root by Glomus mossae. The results didn’t show effect the environmental stresses on comparability reproductive for Glomus mossae fungi associated with wheat … …American Journal of Agricultural and Biological Sciences, Vol. 15, Issue 1 · 20 Mar 2020 · 7,124 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Magnesium on Photosynthetic Characteristics and Growth Effects of Sugarcane at Seedling StageChao Zheng, Yong-Xiang Huang, Ke-Xing LiuIn this study, the effects of different concentrations of magnesium on photosynthetic characteristics and growth of sugarcane cultivars Roc22 and YT00-236 at seedling stage were investigated by combined cultivation of sand culture with nutrient solution. The results showed that under the stress of low magnesium, the synthesis and photosynthesis of chlorophyll are blocked with significantly decreased biomass accumulation, increased root-shoot … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 1 · 15 Mar 2019 · 8,734 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Influence of Partial Substitution of Potassium by Sodium on the Growth Effect of SugarcaneChao Zheng, Yong-Xiang Huang, Jin Li et al.The effects of different potassium and sodium levels on the growth of Taisugar No. 22 (ROC22) were studied by potted nutrient solution-sand culture experiment in this paper. The results showed that under low potassium stress (0 mmol/L) supply, the proper application of sodium could significantly promote photosynthesis of sugarcane and dry matter accumulation, reduce root shoot ratio and promote shoot … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 12 Jun 2018 · 11,317 accessesView PDFCite
Research ArticleOpen accessIn the abstractMorpho-Physiological and Genetic Responses of Bali Local Rice Cultivars to Drought Stress at Seedling StageMade Pharmawati, Luh Putu WrasiatiRice is the main food source in many countries in the world. One of the major limiting factors for rice growth and productivity is drought stress. In Bali there are several local rice cultivars, two of them are ‘Mansur' and ‘Putih Cempaka'. The cultivar ‘IR 64' is one rice cultivar released by IRRI. The responses of those rice cultivars to … …OnLine Journal of Biological Sciences, Vol. 18, Issue 1 · 29 Mar 2018 · 7,647 accessesView PDFCite
Research ArticleOpen accessIn the abstractLead Phytotoxicity Induced Changes in Biochemical Markers in Germination and Seedlings in Durum Wheat Triticum durum Desf. Cv.Vitron and GtaSoraya Slimani, Mokhtar Boudelaa, Saddek Abdelmadjid et al.Among the heavy metals most commonly found on land, lead is a strongly represented pollutant in soil and sediments. It is easily absorbed and accumulated in different parts of plants. On the macroscopic scale, lead causes unfavorable effects on plants. First and in the event of excess, it may exert toxicity affecting several stages of germination development in leaf formation … …American Journal of Environmental Sciences, Vol. 13, Issue 4 · 6 Sep 2017 · 7,482 accessesView PDFCite
Case ReportOpen accessIn the abstractBending Stress and Deflection Analysis of Meshing Spur Gear Tooth during the Single Tooth Contact with Finite Element Method and Determination of the Bending StiffnessAntonios D. Tsolakis, Konstantinos G. Raptis, Maria D. MargaritouPurpose of this study is the study of loading and contact problems encountered at rotating machine elements and especially at tooth gears. Tooth gears are some of the most commonly used mechanical components for rotary motion and power transmission. This fact proves the necessity for improved reliability and enhanced service life, which requires precise and clear knowledge of the stress … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 3 Jun 2017 · 7,648 accessesView PDFCite
Research ArticleOpen accessIn the abstractCrop Yield Prediction in Niger Using Machine Learning TechniquesMahaman Lawali Inoussa Garba, Naroua Harouna, Chaibou Kadri et al.Agriculture is the most impactful sector on Niger's economic growth. Stresses related to climate change and the environment are leading to a continuous decline in crop yield. Accurate crop yield forecasting is of paramount importance for farmers, government, policy makers, and other stakeholders to make most appropriate decisions regarding resource allocation and food security. This study examines the power of … …Journal of Computer Science, Vol. 21, Issue 8 · 16 Sep 2025 · 5,799 accessesView PDFCite

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 · 9,527 accessesView PDFCite
