Research ArticleOpen accessEvery word in the titleEffect of Maturity Stage of Papaya Maradol on Physiological and Biochemical ParametersLaura E. Gayosso-García Sancho, Elhadi M. Yahia, Miguel Angel Martínez-Téllez, Gustavo Adolfo González-AguilarProblem statement: Nowadays, the worldwide increase in diseases has motivated consumers to increase the intake of fruits and vegetables, in response to various research reports indicating that fruits and vegetables can help prevent certain types of illnesses, due to their potentially high antioxidant properties. We evaluated the effect of the stage of ripeness of papaya fruit (Carica papaya L.) on … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 11,270 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInfluence 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 accessEvery word in the titleConstruction Stage Analysis for a New Mixed Structure Building in MilanMarco Zucca, Nicola Longarini, Federico de Socio, Iacopo MiglioriIn this study the Construction Stage Analysis (CSA) of a new mixed structure building is discussed in order to identify the best timing and execution activities scheduling. The building is part of a new university campus that will be realized close to the center of the city. The CSA is carried out by the implementation of two models: the finite … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 6 Mar 2018 · 9,132 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTwo-Stage Estimation in Inverse Problems using Combined Wavelet Thresholding and Penalized Maximum LikelihoodRobert G Aykroyd, Hassan AljohaniInverse problems occur in a wide range of practical scientific investigations where the variables of interest are only observed indirectly, such as magnetic and seismic imaging in geophysics, electrical tomography in industrial process monitoring, or PET scanning in medicine. Linear inverse problems can be thought of as highly multivariate regression problems with strong multicollinearity where the aim is to interpret … …Journal of Mathematics and Statistics, Vol. 13, Issue 3 · 29 Sep 2017 · 7,928 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Salt Stress on Ion Balance at Vegetative Stage in Rice (Oryza sativa L.)Kirill V. Azarin, Andrey V. Alabushev, Alexander V. Usatov et al.Rice (Oryza sativa L.) plants were subjected to NaCl stress within 35 days. The shoot dry weight, root dry weight, total survival percentage and contents of inorganic ions in dry samples of stressed plants were measured to identify the physiological adaptive mechanisms by which rice plants at vegetative stage tolerate salt stresses. Laboratory testing of the 10 rice cultivars showed … …OnLine Journal of Biological Sciences, Vol. 16, Issue 1 · 21 Mar 2016 · 7,472 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOn Nonlinear Age- and Stage-Structured Population ModelsArild WikanThe scope of this review article is to present and discuss various aspects of discrete nonlinear age- and stage-structured population models. We show that such models cover species which exhibit a wide range of different life histories and that one may use them in order to deduce fairly general ecological principles with respect to stability and dynamical outcomes. From a … …Journal of Mathematics and Statistics, Vol. 8, Issue 2 · 6 Jul 2012 · 7,057 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Graphical Based Method for a Class of One-Stage Bounded Variables and Single Constrained Linear Programming ProblemsSuwitchaporn Witchakul, Prapaisri Sudasna-na-Ayudthya, Peerayuth Charnsethikul, Kamlesh MathurAn efficient and effective special purpose method is proposed for solving a class of one-stage single constrained linear programming problems with a finite number of right hand side scenarios and bounded variables. We compare our proposed method with a general purpose method using CPLEX interactive optimizer. For various m and n, by using elapsed computational time as the criteria, our … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 6,922 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThermodynamic Investigation of Two-Stage Absorption Refrigeration System Connected by a CompressorL. Kairouani, E. Nehdi, R. B. IffaThe present work is to analyze a two-stage cycle based on the ammonia-water absorption system, with intermediate compression. The two generators of the system are heated by geothermal energy at low temperature. The study shows that this system makes it possible at lower generator temperature, under the limits permitted by the systems suggested up to now. For Tg = 335 … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 6,741 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Dietary Emamectin Benzoate at Recommended and Overdose Levels on the Pathophysiological Responses and Tolerability of Oreochromis niloticus at Fry StageJasmine Singha, Thangapalam Jawahar Abraham, Satyen Kumar Panda, Prasanna Kumar PatilEmamectin Benzoate (EB) has been recommended as a feed additive for the control of fish ectoparasites. This investigation examined the impact of dietary EB on physiological responses, antioxidant defence mechanisms, and histopathological changes in key organs, and on the kinetics of residue deposition and elimination in the muscle of Oreochromis niloticus fry. Fry were administered EB feeds at 50 µg … …American Journal of Pharmacology and Toxicology, Vol. 20, Issue 1 · 1 Jul 2026 · 1,486 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Metaheuristic-Optimized Feature Selection for Early-Stage Diabetes Prediction With SHAP-Guided Insight into Influential AttributesEsmay Azam Rochy, Jannatul Ferdaus, Uzzal Biswas et al.Diabetes is a metabolic disorder that causes elevated blood glucose. This long-term health condition can lead to cardiovascular diseases, stroke, kidney failure, visual impairment, neuropathy, and even death in critical cases. So, a Computer-Aided Diagnostic (CAD) system is necessary to diagnose diabetes automatically. A clinician can utilize a machine learning-based CAD system that automatically diagnoses many people. This paper will … …Journal of Computer Science, Vol. 22, Issue 2 · 24 Feb 2026 · 1,744 accessesView PDFCite
