I started to read with great interest the case report entitled “Autologous adipose tissue-derived stem cells induce persistent bone-like tissue in osteonecrotic femoral heads” by Pak (1). However, the contents of the report were greatly disappointing. The most critical fault of this report is that the area in which the author observed magnetic resonance imaging (MRI) signal change after injecti...

PURPOSE Nasopharyngeal inflammatory pseudotumor (NIPT) is hard to differentiate from infiltrating nasopharyngeal carcinoma (NPC) on conventional magnetic resonance imaging (MRI). The purpose of this study is to determine whether discrepant lesion sizes estimated on T1- and fat-suppressed T2-weighted images can help distinguish between NIPT and NPC. METHODS We retrospectively reviewed MRI data...

Dengue Hemorrhagic Fever (DHF) is a tropical disease that always attacks densely populated urban communities. Some factors, such as environment, climate and mobility, have contributed to the spread of disease. The Aedes aegypti mosquito an agent dengue virus in humans, by inhibiting its life cycle it can reduce Therefore, necessary involve dynamics mosquito's model order obtain reliable risk ma...

The concept of low impact development LID is to apply decentralized on-site runoff source control to preserve the watershed hydrologic and ecological functions. An integrated layout using bioretention and vegetated landscape can decrease the developed runoff volume and peak flow. One of the key factors in urban hydrology is the imperviousness in the watershed. The conventional approach is to we...

Modelling approaches for relating discharge to the biology of Atlantic salmon, Salmo salar L., and brown trout, Salmo trutta L., growing in rivers are reviewed. Process-based and empirical models are set within a common framework of input of water flow and output of characteristics of fish, such as growth and survival, which relate directly to population dynamics. A continuum is envisaged incor...

Environmental indices (EI) are common communication tool used to describe the overall status of environmental systems (e.g. air, water, soil). Development of EI entails the use of mathematical operators to aggregate various non-commensurate input parameters in a logical manner. Ordered weighted averaging (OWA) operator is a general mean type operator that provides flexibility in the aggregation...

Recently, the Guaranteed Frame Rate (GFR) service category has been proposed to provide bandwidth guarantees with a simpler implementation than ABR in ATM networks. In this paper, we study the performance of TCP in LAN and WAN ATM networks supporting the GFR service category. We present simulations where each TCP connection is carried by one GFR VC with a minimum guaranteed bandwidth. We consid...

Decisions on irrigation water management are usually made at different levels, including farms, user associations (WUAs), and regional planning agencies. The latter generally have good access to information decision tools regarding resources management. However, these remain out of reach the final users, namely farmers. study, conducted in irrigated district Cherfech, north Tunisia, had main ob...
