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...

The majority of organisms can be grouped into those relying solely on photosynthesis (phototrophy) or those relying solely on the assimilation of organic substances (heterotrophy) to meet their requirements for energy and carbon. However, a special life history trait exists in which organisms combine both phototrophy and heterotrophy. Such "mixotrophy" is a widespread phenomenon in aquatic habi...

cated no differences (P > 0.10) between the corn rootworm protected corn and non-transgenic control corn for nitrogen intake (0.04 versus 0.04 lb/d), nitrogen digested (0.03 versus 0.03 lb/d), nitrogen retained (0.01 versus 0.01 lb/d), or nitrogen digestibility (77.30 versus 78.30%), respectively. The results of this experiment indicate that energy and nitrogen utilization are similar between d...

This study was designed to examine carbon utilization within scalable microalgae production systems. Neochloris oleoabundans was produced in replicated troughs containing BG11 nutrient formulation. Atmospheric CO(2) was supplemented with ∼5% CO(2) or with NaHCO(3), and the pH of troughs receiving NaHCO(3) was adjusted with HCl or H(3)PO(4). Peak biomass concentrations reached 950, 1140, or 850 ...

BACKGROUND A cost-sharing drug insurance plan has been implemented among people receiving social assistance who had previously free access to medications. OBJECTIVE To assess the impact of this drug plan on the use of three classes of medications: inhaled corticosteroids, neuroleptics and anticonvulsants. METHODS From the computerized drug databases of the Régie de l'assurance maladie du Qu...

This paper presents a new range query mechanism to query encrypted databases that reside at third-party, untrusted, servers. This paper is a continuation of work done by others [1]; our scheme seeks to improve the precision of querying encrypted data sets, increase the utilization of server side processing and reduce the computation and memory utilization on the client side. We compare our algo...

Forty primary clinical isolates and 50 stock cultures of corynebacteria and coryneform bacteria were tested with the Minitek system (BBL Microbiology Systems, Cockeysville, Md.). The Minitek correctly identified all of these organisms, including JK group isolates, within 12 to 18 h of incubation. The method does not require serum supplements for testing carbohydrate utilization by the bacteria....
