PURPOSE To compare fibroplasia and the resistance of the abdominal wall when polypropylene meshes and polypropylene/poliglecaprone are used. METHODS Seventy-seven male Wistar rats were divided into three groups: Control Group (for resistance); Group E (polypropylene mesh); and Group U (polypropylene/poliglecaprone mesh). The animals in Groups E and U had a standard muscular and aponeurotic de...

In the present work, emission of volatile organic compounds (VOCs) from plastic packaging materials and their migration to packaged product was investigated. Fresh-cut artichokes were chosen as a case study owing nutritional profile, including phenolic compounds, antioxidants, inulin fiber, high market demand. Artichokes cut into quarters, in active modified atmosphere (5% O 2 10% CO ) three di...

Transient electronics are becoming a hot topic due to the rapid development of bioelectronics, self-destructive devices and environmental sensors. This letter reports a novel scheme for triggering degradation of 250 μm-thick Mg target using acetic acid regarding transient electronics applications. The triggered transience has also been demonstrated using commercial vinegar. To achieve programma...

This present study was elucidated the cytological effects of maize due to ageing (storage) in different packaging material. This study revealed that the cytological anomalies in somatic cells of maize inbreds (CM-138 and CM-142) due to storage in jute and plastic bags. For the cytological impact of storage, inbreds were stored in jute and plastic bags for different periods i.e. 4, 8 and 12 mont...

Side air bags, a relatively new technology designed to protect the head and/or torso in side-impact collisions, are becoming increasingly common in automobiles. Their efficacy in preventing US driver deaths among cars struck on the near (driver's) side was examined using data from the Fatality Analysis Reporting System and the General Estimates System. Risk ratios for driver death per nearside ...

BACKGROUND Although self-inflating bags are widely used for manual hyperinflation, they do not allow ventilation parameters, such as pressure or volume, to be set. We studied the ventilation performance of neonatal and pediatric self-inflating bags. METHODS We asked 22 physiotherapists to manually hyperinflate 2 lung models (neonatal and pediatric), using self-inflating bags from 3 manufactur...

As a growing number of protein drug products are developed, formulation characterization is becoming important. An IgG product tested at concentrations from 0.0001 mg/mL - 0.1 for adsorption behavior to polymer surfaces polyvinyl chloride (PVC) and polypropylene (PP) upon dilution in normal saline (NS) using quartz crystal microbalance with dissipation (QCM-D). The studies mimicked antibody int...

Radon detectors are widely used for research and for monitoring indoor and outdoorradon. During some applications, detectors need to be enclosed in barrier bags which arecompletely transparent to radon. In other applications, radon detectors need to beenclosed in barrier bags that are opaque to radon. In certain applications, barrier bagsmay provide resistance to human manipulat...

plastics, one of the most abundant materials in the world today, are one of the main sources of pollution. people’s perception of using and disposing plastic bags is primordial as they tend to be a major part of household solid waste. this study aims to determine community’s perception of usage and disposal of plastic bags in eastern ethiopia. a quantitative cross-sectional study has been condu...
