Research ArticleOpen accessEvery word in the titleAnalysis of the Cytogenetic Status, Genome Instability, and Adaptive Potential of the Kazakh Tobet DogOksana Cherednichenko, Anastassiya Pilyugina, Dinara Azizbekova et al.In recent years, interest in indigenous dog breeds has increased. The Tobet is a unique breed of Kazakh livestock guardian dogs adapted to nomadic pastoralism that developed over thousands of years across Central Asia and Turkestan. Currently, the Tobet breed faces critical endangerment. Its conservation and sustainable breeding require thorough analysis of hereditary characteristics, genome stability, and adaptive potential. In … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 4 · 19 Feb 2026 · 1,891 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGeometrical and Physical Effects on the Instability of a Fluid-Conveying PipeDahmane Mouloud, Samir Zahaf, Benkhettab Mohamed et al.The endeavor of this paper is to calculate frequencies and critical velocity of pipe carrying incompressible fluid are obtained using standard finite element method. Finite element beam type with two degrees of freedom per node was used. The natural frequencies of our system are calculated by using a program developed on MATLAB. The results are compared with those predicted by … …Current Research in Bioinformatics, Vol. 9, Issue 1 · 2 Nov 2020 · 11,324 accessesView PDFCite
Review ArticleOpen accessEvery word in the titlePolitical Instability and Firm Performance: A Microeconomic Evidence from Ivory CoastErnest Ouédraogo, Ibrahim Ouédraogo, Emmanuel LompoIn this paper, we investigate how political instability affects firms’ performance in Ivory Coast. Using data from the World Bank's 2016 survey of 361 firms in Ivory Coast, we perform a robust endogenous treatment model to assess causal the impact of political instability on firm productivity. The results indicate that political instability is statistically significant and negatively associated with firm … …American Journal of Economics and Business Administration, Vol. 12, Issue 1 · 23 Oct 2020 · 9,178 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCyclic Instability of Shape-Memory Alloys in Seismic Isolation SystemsFilipe Amarante dos Santos, Corneliu Cismasiu, Francisco Braz FernandesShape-memory alloys are being progressively introduced as kernel components in seismic retrofitting devices for civil engineering structures. In order to control the instability associated with the first mechanical cycles, a training procedure is usually implemented, which stabilizes the superelastic behavior of the alloy. This paper addresses the characterization of the cyclic behavior of an austenitic NiTi alloy with emphasis on … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 7 Jan 2018 · 6,854 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePOWER STABILITY MONITORING BASED ON VOLTAGE INSTABILITY PREDICTION APPROACH THROUGH WIDE AREA SYSTEMH. H. Goh, Q. S. Chua, S. W. Lee et al.Nowadays, power systems are being forced to operate closer to its security limit due to current economic growth and the difficulties to upgrade the existing grid infrastructure. With the sudden increment of power demand, voltage instability problem has become a main concern to the power system operator because voltage instability has led or crucially contributed to some major blackouts throughout … …American Journal of Applied Sciences, Vol. 11, Issue 5 · 10 Feb 2014 · 7,143 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Effects of Fatigue and Chronic Ankle Instability on Dynamic Postural ControlSeyed Hossein Hosseinimehr, Hassan Daneshmandi, Ali Asghar NorastehProblem statement: The proprioception information is a prerequisite for balance, body's navigation system and the movement coordinator. The aim of this study was to investigate the effects of fatigue and chronic ankle instability on dynamic postural control. Approach: Thirty physical education students (14 males, 16 females) in two groups (15 healthy age = 21.78±0.79 years, height = 168.3±5.6 cm and … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 8,870 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInteraction of Export Instability and Openness-Growth Nexus In East Asia and Pacific Countries (1990-2006)Zamanian Gholamreza, Pourshahabi Farshid, Shirazi AliProblem statement: Because of the importance of the relation between instability of economic variables and making decision for determinants, this is so considerable to find the interaction between instability and economic variables’ activity. Approach: One of the efficacious factors to have a positive trade balance is export that is a factor of GNP growth too. Moreover, openness is an important … …American Journal of Economics and Business Administration, Vol. 2, Issue 1 · 31 Mar 2010 · 7,846 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSociopolitical Instability and Capital Accumulation in Developing Countries: Cross Country pooled data EvidenceAbdul Haque, Selvarathinam Santhirasegaram, Muhammad YounisThis study shows that sociopolitical conflicts measured by peace building capacity in developing countries affect physical and human capital accumulation in selected 70 developing countries from all regions of the world during 2000-2004 by using econometric models. We conclude that sociopolitical instability negatively and significantly effect both physical and human capital accumulation in selected countries. Sociopolitical stability in developing countries … …Journal of Social Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 7,871 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSociopolitical Instability and Economic Growth Empirical Evidence from Sri LankaChangsheng Xu, Santhirasegaram Selvarathinam, Wen Xing LiSociopolitical instability severely affects economic growth in short and long run. This study analyzes that sociopolitical instability measured by proxy measure; annual growth rate of tourist arrivals in Sri Lanka during 1960-2005 adversely affects economic growth. Our empirical findings based on ordinary lease square econometric estimation, show that sociopolitical instability negatively and significantly affect economic growth. Reduction of economic growth … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 6,879 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNumerical Study of Static Instability of Pipe Conveying Incompressible Fluid under Different Boundary ConditionsDahmane Mouloud, Zahaf Samir, Sid Ahmed Slimane et al.In this article, the influences of uniform velocity profile, mass ratio, length and Winkler elastic foundation on the static instability of pipe conveying incompressible fluid are investigated. The Euler-Bernoulli beam theory is employed to derive partial differential equation of pipes carrying fluid. The results were carried out using ANSYS Workbench program, where the analysis is based on the numerical solution; … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 26 Nov 2020 · 6,577 accessesView PDFCite
