The temperature profile of infectious laboratory waste being autoclaved was examined relative to the type of containers used in the process. A standardized waste load (1,750 +/- 4 g) placed in the container was evaluated by using a direct readout thermocouple. The sensor of the thermocouple was placed within an unused and outdated agar plate, centrally located about 5 cm from the bottom of the ...

The goal of this study is to assess the fresh and hardened properties self-compacting concrete (SCC) prepared using locally available materials. This research includes also impact polypropylene (PP), steel hybrid fibers on same properties. In addition, mechanical SCC specimens (with without fibers) at high temperatures, including as compressive, tensile, flexural strengths, will be determined. ...

Heterotrophic bacteria (11 genera, 14 species, 25 putative strains) were isolated from drinking water, identified either biochemically or by partial 16s rDNA gene sequencing and their adherence characteristics were determined by two methods: i. thermodynamic prediction of adhesion potential by measuring hydrophobicity (contact angle measurements) and ii. by measuring adherence to eight differen...

In many structural applications, concretes reinforced with short metal or synthetic fibers (fiber-reinforced concrete (FRC)) have a number of advantages over traditional steel rebars reinforcement, such as easier and more economical production, wear resistance, impact integrity, etc. the present study, several mixes were developed prismatic FRC specimens fabricated. Their behaviors studied usin...

The experimental study deals with Hybrid fibre reinforced concrete with the use of (Polypropylene and Recycled polyethylene terephthalate RPET). The M40 grade concrete used was designed by using IS10262-2009 code. The steel fibre and synthetic fibre were added at the volume fractions up to 0.5%. Test results showed that the fibres, when used in a hybrid form, could result in superior composite ...
