The interrelated issues of capacity utilization (CU) and technical efficiency (TE) have received global importance as they relate to the problem of overcapitalization and overfishing. Given the limited research on these issues in the context of small-scale fisheries, this paper attempts to provide empirical estimates of TE and CU with particular focus on small-scale fisheries in Oman using Data Envelopment Analysis (DEA). The output variables included aggregated catch of three fish categories namely ...

Physical inactivity and ageing are widely recognized as risk factors for development of coronary artery disease. One of the characteristic changes that occurs in aged coronary artery is downregulation of their large-conductance voltage- and calcium-activated K(+) (BK(Ca)) channels. In this study, we investigated the effects of moderate exercise training (ET) on the activity of BK(Ca) channels in coronary arteries of aged rats. Old Fischer 344 rats (23-26 months old) were randomly assigned to sedentary ( ...

Studies related to ethnomedicines investigate the way people manage illness and diseases because of their cultural perspective. Fields like ecology, epidemiology, and medical history jointly contribute to the broad field of ethnomedical study. The knowledge gathered by traditional healers in the villages and tribal communities on natural medicines remains unfamiliar to the majority of scientists and the general population. The study of ethnomedicine principally involves the compilation of empirical ...

Non-tuberculous mycobacteria (NTM) are an unusual cause of osteomyelitis. Mycobacterium farcinogenes is an uncommon cause of human disease. We describe here the first case of M. farcinogenes osteomyelitis in a 49-year-old man who underwent left knee anterior cruciate ligament and medial meniscal repair which was complicated by recurrent septic arthritis and surgical site infection. As a consequence, he underwent multiple surgical debridements. Ultimately, left proximal tibial osteomyelitis was diagnosed ...

This paper investigates the extent, dynamics, and factors influencing technical efficiency (TE) and capacity utilisation (CU) in small-scale fisheries (SSF) using a two-stage data envelopment analysis (DEA) approach covering the period 2010–2012. A considerable extent of boat-level technical inefficiency, capacity underutilisation and scale inefficiency were evident. On average, TE and CU levels under the constant returns to scale (CRS) and variable returns to scale (VRS) models declined over time. The ...

The impact of chemical reactions on the double-diffusive convective motion in a non-Newtonian viscoelastic fluid (Kuvshiniski type) saturated porous layer is examined applying both linear and nonlinear stability techniques. The Darcy model that includes the Kuvshiniski type viscoelastic effect of viscoelastic fluid and the Boussinesq estimation is employed as the momentum equation. The conditions for the occurrence of the stationary and oscillatory style of convective motions are determined by applying ...

The growth in Internet has led to expansion of e-banking, forming online services, like financial services, account opening and facilities (Kolodinsky et al, 2004). Banks manage risks in some areas like: strategy, credit, market, liquidity etc. (Gorgisco, 2006). However, the growth of e-banking become vulnerable to the challenges it faces. All organisations conducting their business on-line have to focus on controlling the associated risks; e-banking is no exception. Malisuwan (2006) categories these ...

Aflaj forms a significant water resource system in the Sultanate of Oman of which 92% is used for irrigation purposes while the rest is used for domestic works. Continous human interventions in this system are causing adverse effects on the natural flowing water quality before it can reach the end users. This research work assesses the quality of the Aflaj water system in the Wilayat of Samail, Sultanate of Oman. Also, various physical, chemical and biological parameters have been evaluated. It ...

Ground and natural flow surface water are the dominant water resources in different parts of the Sultanate of Oman. The people of wilayat (town) Samail, Sultanate of Oman use both ground and surface water for their daily activities. Due to continuous exploitation of water resources and human activity, the quality of both ground and surface water getting deteriorated. In the present study, the ground and surface water quality were assessed by considering 32 water samples from wells and open channels ( ...

Delay Tolerant Network suffers from lack of resources and disconnected contact nature. In DTN, all possible methods are used to transmit data including the physical transportations means. Aircrafts in commercial routes have been proposed to carry data from ground users along their flying routes. Delivery probability is compared when using aircrafts, buses and ferries. Results show that aircrafts provide higher delivery probability which is up to 62% better compared with buses and ferries. Furthermore, ...

Ion channel remodeling is a dynamic process that occurs in response to various physiological and pathophysiological conditions including advanced age. One of the characteristic changes that occur in coronary arteries with ageing is down-regulation of calcium-activated potassium (KCa) channels. In this study, we investigated the effect of exercise training on age-induced down regulation of KCa channels in coronary vascular smooth muscle cells. Aged F344 (23–26 months old) rats underwent a progressive ...
