Research ArticleOpen accessEvery word in the titleImpact of Long-Term use of Mobile Phones on the Prostate in Human usersMadyha Hassan Mahmoud, Nadia Youssef Morcos, Khadiga Salah Ibrahim et al.The current study investigated some possible effects of long-term use of mobile phones on the oxidative-antioxidants balance and its effect on the prostate. Twenty-eight eligible volunteers frequently use mobile phones and from the same socioeconomic status were enrolled in the study. They were examined according to the effect of time every two years for a follow-up period with four years. … …OnLine Journal of Biological Sciences, Vol. 20, Issue 4 · 24 Dec 2020 · 6,438 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Phenomenon of Nonzero Norm of Long-Term Changes in the Total Water Supply in River BasinsViktor V. Kovalenko, Ekaterina V. GaidukovaIn hydrology, the norm of changes in water supply is considered to be equal to zero, under long-term averaging. This assumption allows for calculating and mapping the long-term evaporation rates linked by the water balance with maps of precipitation and river runoff. The phenomenon of nonzero norm of change of the total water supply is provided using the effect of … …American Journal of Environmental Sciences, Vol. 11, Issue 2 · 27 May 2015 · 6,636 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCOMBINING LONG MEMORY AND NONLINEAR MODEL OUTPUTS FOR INFLATION FORECASTHeri Kuswanto, Irhamah, Laylia AfidahLong memory and nonlinearity have been proven as two models that are easily to be mistaken. In other words, nonlinearity is a strong candidate of spurious long memory by introducing a certain degree of fractional integration that lies in the region of long memory. Indeed, nonlinear process belongs to short memory with zero integration order. The idea of the forecast … …Journal of Mathematics and Statistics, Vol. 10, Issue 3 · 7 Jul 2014 · 6,984 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePower-Voltage Characteristics of Power System with the Long Transmission LinePrechanon KumkratugProblem statement: Power- Voltage curve provides very important information for voltage stability analysis. The exact long transmission line model consists of the resistance and the reactance. The resistance causes in the active line loss. It is not easy task to achieve the power-voltage curve characteristics of power system with the exact long line model. Approach: This study applies the concept … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 10 Aug 2012 · 8,679 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleThe Mathematical Model of Power System with Static Var Compensator in Long Transmission LinePrechanon KumkratugProblem statement: It is becoming increasingly important to fully utilize the existing transmission system assets due to environmental legislation, rights-of-way issues and costs of construction and deregulation policies that introduced in recent years. The Static Var Compensator (SVC) has been proposed for the better control power flow and dynamic performance. The exact long transmission line model consists of the resistance … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 15 Mar 2012 · 7,099 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImpact of Shrimp Farm Effluent on Water Quality in Coastal Areas of the World Heritage-Listed Ha Long BayThuyet D. Bui, Jim Luong-Van, Chris M. AustinProblem statement: Shrimp farming has rapidly developed in coastal areas of the World Heritage-listed Ha Long Bay since the last decade. Effluent discharged from shrimp farms with high levels of nutrient waste may cause eutrophication in receiving waterways. Therefore, assessing water quality at tidal creeks receiving shrimp farm effluent in coastal areas of Ha Long Bay supports environmental protection and … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 3 Mar 2012 · 11,289 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleAn Innovative Technique of Texture Classification and Comparison Based on Long Linear PatternsV. Vijaya Kumar, B. Eswara Reddy, U. S.N. Raju, K. Chandra SekharanThe present paper proposes a method of texture classification based on long linear patterns. Linear patterns of long size are bright features defined by morphological properties: linearity, connectivity, width and by a specific Gaussian-like profile whose curvature varies smoothly along the crest line. The most significant information of a texture often appears in the occurrence of grain components. That’s why … …Journal of Computer Science, Vol. 3, Issue 8 · 28 Aug 2007 · 6,726 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLong Cycles in Employment, Inflation and Real Unit Wage Costs, Qualitative Analysis and Quantitative AssessmentPeter Flaschel, Goeran Kauermann, Timo TeuberThis study provided some theoretical foundations for the empirical hypothesis. At first presented two simple prototype models of inflation, stagflation and disinflation. We concluded that there are cycles with a phase length much longer than the ordinary business cycle (in fact approximately five times as long as we saw in the empirical phase plots of the paper) which are not … …American Journal of Applied Sciences, Vol. 2, Issue 13 · 18 Dec 2005 · 8,592 accessesView PDFCite
