AIM There are few complications associated with harvesting of full thickness coastal cartilage grafts i.e., pneumothorax (0.9%), contour deformities and prolonged post-operative pain. To address these issues, authors devised special scalpel to harvest split-thickness costal cartilage grafts. MATERIALS AND METHODS Standard inframammary incision was used for harvesting rib. Incision was made di...

Post-consumer waste is a small contributor to global greenhouse gas (GHG) emissions (<5%) with total emissions of approximately 1300 MtCO 2-eq in 2005. The largest source is landfill methane (CH 4), followed by wastewater CH 4 and nitrous oxide (N 2 O); in addition, minor emissions of carbon dioxide (CO 2) result from incineration of waste containing fossil carbon (C) (plastics; synthetic texti...

Introduction: Biomedical waste is any unwanted residual matter arising from the hospital and other health care settings. Biomedical waste management means a systematic way of disposing the health care waste. Lab Technicians involve in segregation, storage, transportation and disposal. Objective: To assess the knowledge and practice of biomedical waste management and to determine the effectivene...

This paper presents the design and implementation of a rectifier for piezoelectric energy harvesting based on the parallel-synchronized-switch harvesting-on-inductor (P-SSHI) technique, also known as bias flip circuit[1]. The circuit is implemented with 0.25 μm CMOS high voltage process with only 0.9648 mm chip area. Post-layout simulation of the circuit shows the circuit extracts 336% more pow...

Post-consumer carpet represents a high volume, high energy content waste stream. As a fuel for co-firing in cement kilns, waste carpet, like waste tires, has potential advantages. Technological challenges to be addressed include assessing potential emissions, in particular NO emissions (from nylon fiber carpets), and optimizing the carpet feed system. This paper addresses the former. Results of...

BACKGROUND Semitendinosus and gracilis muscles whose tendons are used in surgical reconstruction of the anterior cruciate ligament maintain their contractile ability, and a limited decrease of hamstring muscles force is observed postoperatively despite important changes. The goal was to quantify the influence of the myofascial structures on excursions and moment arms of knee muscles to attempt ...

background: monitoring of indicator and pathogenic microorganisms is essential for proper composting. the aim of this study was to evaluate the change in population of coliform bacteria and salmonella spp. in composting process of municipal wastes and after its application on soil. methods: the samples were taken from each raw waste pile, initial pile, and active phase pile, cooling phase pile ...

 Post larvae of wild and cultured spawners of the Indian white shrimp (Penaeus indicus, Milne Edwards, 1837) were reared to market size, in commercial ponds of shrimp farming site of Helleh, in Bushehr Province, during a six months period. Environmental factors, management process and the diet used to feed shrimps were almost similar for both treatments. Averages of the weight, length, specific...
