The aim of this study was to improve the strength black cotton soil for its suitability road subgrade construction using wastes from plastic bottles and glass waste powders. Currently, nondecomposable glasses have become threats human health environment. This used replace cement, since cost cement raised due energy raw material use as stabilizer in weak soil. powder (WGP) chips were mixed with ...

It is possible to elaborate adequate methodologies for collecting social wasps from the knowledge of their behavior. Thus, objective present study was compare attractiveness different sized PET bottles (plastic soda bottles) (by volume), types juice and variety attractive flavors in elaborating traps optimize method diverse works involving wasps. The work elaborated Botanical Garden Federal Uni...

Procedures have been designed to test specimen containers for leakage, using blood and aqueous fluorescein solution as indicators. They have been used in a trial evaluation of a number of commercially available containers intended for medical specimens. Glass bijou bottles, evacuated container systems, and several types of plastic container showed no significant leakage rate with either blood o...

Floating persistent debris, primarilymade fromplastic, disperses long distances from source areas and accumulates in oceanic gyres. However, biofouling can increase the density of debris items to the point where they sink. Buoyancy is related to item volume, whereas fouling is related to surface area, so small items (which have high surface area to volume ratios) should start to sink sooner tha...

This study reports the stability of extemporaneously prepared gabapentin oral suspensions prepared at 100 mg/mL from bulk drug and capsules in either Oral Mix or Oral Mix SF suspending vehicles. Suspensions were packaged in amber plastic bottles and amber plastic syringes at 25°C / 60%RH for up to 90 days. Throughout the study period, the following tests were performed to evaluate the stability...

Due to intensive utilization and extensive production, plastic waste is becoming a serious threat the environment human health. The situation even worse in countries such as United Arab Emirates (UAE), where single-use water bottles add load of pollution. main objective this survey was assess extent bottled by UAE residents their awareness environmental concerns arising from bottles. aim also e...

Conversion of urban wastes to utilizable sugars is very important as a vital step towards reduction environmental pollution. Consequently, this work was aimed at obtaining cellulase from the gut Oryctes rhinoceros larvae raffia palms in Itokin, Lagos State, Nigeria evaluate its degradability potential on different plant leaves and selected plastic bottles. Cellulase partially purified by combin...

The possibility of obtaining a filament for 3D printing from plastic bottles based on polyethylene terephthalate is investigated. A preliminary heat treatment the material proposed, which allows powder with minimal energy consumption dispersion. temperature regime processing an extrusion line single-screw extruder subsequent cooling melt before winding coils determined. Comparative strength tes...

Bisphenol A (BPA) is a chemical agent used in the production of epoxy resins and polycarbonate plastic products, including water bottles, and as a coating for dental sealants, food/beverage containers, and canned food linings. Exposure to BPA has been linked to such negative health effects as obesity and heart disease. Concerns for the effects of BPA are greatest on infants and young children d...

We evaluated the ability of UNICEF-designed pot-chlorinators to achieve recommended free residual chlorine (FRC) levels in well water in Bissau, Guinea-Bissau, during a cholera outbreak. Thirty wells were randomly selected from six neighbourhoods. Pot-chlorinators--perforated plastic bottles filled with gravel, sand and calcium hypochlorite granules--were placed in each well. FRC was measured b...
