Antimicrobials, chemotherapeutics or antibiotics?
Antimicrobials are the broad classes of substances acting against microorganisms. As there is a need for stability and consistency within Science, this must also be applied to the business of defining the different categories of antimicrobials correctly. This is of special importance, since various compounds known for activities outside this field of interest are now also...

The Turkish real time kinematic GPS network (TUSAGA-Aktif) infrastructure
The concept of Real Time Kinematic (RTK) Network has become popular throughout the world since the beginning of 2000s. The RTK Network server collects satellite observations from the RTK Network, performs calculations and sends RTK corrections to the rover. Thus, these RTK Networks eliminates the need for post-processing GPS observations; instead the users in the field...

Low cost biosorbent banana peel (Musa sapientum) for the removal of heavy metals
The efficacy of the banana peel (Musa sapientum) biomass was tested for the removal of lead, copper, zinc and nickel metal ions using batch experiments in single and binary metal solution under controlled experimental conditions. It is found that metal sorption increases when the equilibrium metal concentration rises. At highest experimental solution concentration used (150...

Thermal comfort of multiple-skin facades in warm-climate offices
A multiple-skin facade is an envelope construction that consists of two transparent surfaces separated by a cavity. The extra skin can reduce both cooling demand in summer and heating demand in winter. Solar radiation entering through the outer skin on the south face of the building will heat the air in the cavity. Depending on whether there is a demand for heating or cooling,...

Box-Muller harmony search algorithm for optimal coordination of directional overcurrent relays in power system
Directional overcurrent relays are used to protect interconnected power systems and looped distribution systems. The problem is modeled as a constrained nonlinear optimization problem in which the decision variables are the devices that control the act of isolation of faulty lines from the system without disturbing the healthy lines. Time dial setting (TDS) and plug setting...
