Masonry workers face some of the highest physical demands in the construction industry where large bags of masonry material weighing 42.7 kg are commonly handled by mason tenders who mix the mortar, distribute mortar and bricks/blocks, and erect/dismantle scaffolding throughout the day. The objective of this study was to determine the effectiveness of using half-weight bags (21.4 kg) on reducin...

Air bags, when used as a supplement to safety belts, effectively prevent deaths and serious injuries in frontal motor-vehicle crashes. Air bags are standard equipment in most new cars; federal safety standards require that all new passenger cars and light trucks be equipped with both driver- and passenger-side air bags by 1999. The safety of air bags is well documented, and air bags have saved ...

Recently the need for “digital evidence bags” – a common storage format for digital evidence – has been identified as a key requirement for enabling inter-organisational sharing of digital evidence, and interoperability between forensic analysis tools. Recent work has described an ontology based approach to correlation of event log based evidence, using semantic web technologies for describing ...

In many machine learning applications, labeling every instance of data is burdensome. Multiple Instance Learning (MIL), in which training data is provided in the form of labeled bags rather than labeled instances, is one approach for a more relaxed form of supervised learning. Though much progress has been made in analyzing MIL problems, existing work considers bags that have a finite number of...

We assessed the performance of hermetic triple layer Purdue Improved Crop Storage (PICS) bags for protecting Hibiscus sabdariffa grain against storage insects. The major storage pest in the grain was a bruchid, Spermophagus sp.. When we stored infested H. sabdariffa grain for six months in the woven polypropylene bags typically used by farmers, the Spermophagus population increased 33-fold over...

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...

BACKGROUND High-quality vacuum cleaners and vacuum cleaner bags are often recommended to allergic patients as a means of reducing indoor allergen exposure. A number of vacuum cleaners on the market today claim to capture 99.9% of particles 0.3 microm or larger entering the vacuum cleaner, and many vacuum cleaner bags are now being sold as microfiltration bags. OBJECTIVE The purpose of this st...

Bagging of female inflorescence following pollination has recently received growers attention. Although this process occurs early in the season but affects fruit quality, yield, and marketability. Date palm growers have used to use grocery paper bags for this bagging process. Since inflorescence bagging causes what is called the greenhouse effect, it was very important to investigate the effect...

Prescriptions for intravenous (i.v.) fluids in hospitals may not be closely adhered to. This study prospectively examined whether prescribed i.v. fluids are administered at the correct rate. During a four-week period, the i.v. infusion rates in patients requiring continuous i.v. fluids and cared for by a single medical team in a district hospital were studied. The periods over which i.v. crysta...
