Technical aspects of composite arterial grafting with double skeleton-ized internal thoracic arteries. Bilateral skeleton-ised internal thoracic artery graftings in off-pump coronary artery bypass: early result of Y versus in situ grafts. results of coronary grafting using ultrasonically skeletonized internal thoracic arteries. We read with great interest the recent review from Dr. Ali and cowo...

A comparison of 14 currently applicable wood harvesting systems was assessed with respect to ergonomic point of view. For this purpose, the research method, based on the Hodges-Lehmann rule and the integrated work-severity rate of single machinery, was developed for ergonomic evaluation of cut-to-length, tree-length and full-tree harvesting systems. Altogether, about 130 different parameters of...

BACKGROUND Much research in the field of energy harvesting has sought to develop devices capable of generating electricity during daily activities with minimum user effort. No previous study has considered the metabolic cost of carrying the harvester when determining the energetic effects it has on the user. When considering device carrying costs, no energy harvester to date has demonstrated th...

Most ZigBee sensor networks to date make use of nodes with limited processing, communication, and energy capabilities. Energy consumption is of great importance in wireless sensor applications as their nodes are commonly battery-driven. Once ZigBee nodes are deployed outdoors, limited power may make a sensor network useless before its purpose is complete. At present, there are two strategies fo...

The common property meadows in the Swiss Alps have been managed by local self-organized governance systems since the Middle Ages, thus preventing their overuse. During the past century, socioeconomic developments, such as industrialization and rapid nonagricultural economic growth, have shifted employment opportunities from the agricultural sector towards the service sector. In the agricultural...

By 2030 South Africa (SA), a developing country, is predicted to be severely impacted by physical water scarcity. In order to avert a future water crisis, the country needs to find ways to reduce its reliance on conventional surface water schemes based on impoundments on rivers. Rainwater harvesting (RWH) is an alternative water resource. To date, the viability of domestic RWH within an urban s...

The high quality of Port wine is the result a sequence winemaking operations, such as harvesting, maceration, fermentation, extraction and aging. These stages require proper monitoring control, in order to consistently achieve desired properties. present work focuses on harvesting stage, where sugar content grapes plays key role one critical maturity parameters. Our approach makes use hyperspec...

Energy harvesting, which offers a never-ending energy supply, has emerged as a prominent technology to prolong the lifetime and reduce costs for the battery-powered wireless sensor networks. However, how to improve the energy efficiency while guaranteeing the quality of service (QoS) for energy harvesting based wireless sensor networks is still an open problem. In this paper, we develop statist...

Life is dependent on water. However, in terms of the potential effects, water scarcity quickly emerging as one most critical problems world. To access more fresh for drinking, sanitation, and irrigation, can be harvested from different forms earth. Atmospheric harvesting best alternative producing everyday life reducing global shortages. date, many modern technologies have been introduced this ...
