On Reducing Power Consumption of Transmitting Stations in 802.11 MIMO Networks

We propose an online algorithm for energy minimization of transmitting stations in IEEE 802.11 wireless local area networks (WLANs). Our algorithm configures radio frequency (RF) parameters such as the number of transmitting antennas based on the real-time traffic demand and channel measurements so that the power consumption of the device is reduced and the minimum data rate requirements of statio

Empost-net: Emerging paradigm of sustainable tourism - a network perspective

The EMPOST-NET project studied a new phenomenon: networking across different public and private sectors of society towards the most important goal of today – sustainable development. Sustainability networks are of special importance within the field of tourism, which is among the largest industries of today’s world, yet its environmental and socio-cultural impacts are often given too little attent

Esophageal Dysmotility is More Common Than Gastroparesis in Diabetes Mellitus and is Associated With Retinopathy.

Gastroparesis is a well-known complication of diabetes mellitus, both in symptomatic and asymptomatic patients. Esophageal dysmotility has also been described, but is not as well-characterized. The etiology and effect of these complications need to be clarified. The aim of the present study was to evaluate esophageal and gastric motility, complications, gastrointestinal symptoms, and plasma biomar

Criteria for the Research Institute for Fragrance Materials, Inc. (RIFM) safety evaluation process for fragrance ingredients.

The Research Institute for Fragrance Materials, Inc. (RIFM) has been engaged in the generation and evaluation of safety data for fragrance materials since its inception over 45 years ago. Over time, RIFM's approach to gathering data, estimating exposure and assessing safety has evolved as the tools for risk assessment evolved. This publication is designed to update the RIFM safety assessment proce

Sustainable vehicle fuels - do they exist?

Our aim with this report is to discuss vehicle fuels from a wide perspective of sustainability. Biofuels and electricity are analyzed and compared to fossil vehicle fuels. Our goal is to try to point out the circumstances under which vehicle fuels can be reasonably perceived as sustainable, and which systems we should develop and which we should avoid. The all-embracing conclusion of this study is

Laser Doppler perfusion imaging: New technique for determination of perfusion and reperfusion of splanchnic organs and tumor tissue

Background and Objective: Several investigations indicated that laser Doppler flowmetry on the liver surface reflects relative changes of the total liver blood flow. In this study, Laser Doppler Perfusion Imaging (LDI), monitoring the surface only, was used for measurements of tissue perfusion of normal and/or impaired liver, pancreas, spleen, stomach and intestine, and the blood flow of hepatic t
