Feeling more than usually like the proverbial plodding policeman, I received inspiration as the second large drop of water exploded on the aforementioned pate. Naiis, floor-boards, water-pipes, burst. Don't panic, do something, keep cool, ask wife, Where's wife? Shopping who knows where, for who knows how long. Alright, don't panic, any doctor can cope with emergencies. Turn the water off. Simple.

By using a tridentate N^C^N-coordinating ligand, the luminescence of a cyclometallated Pt(II) complex can be shifted into the blue region, without the problematic drop-off in quantum yield observed for bidentate analogues. The combination of blue-shifted monomer and excimer allows white-emitting OLEDs with high colour rendering index to be produced.

The current advanced technologies in hardware and software for positioning, such as embedded GPS receivers in mobile devices, have eased the acquisition of massive movement data. For example, personal locations can be obtained and registered in social media platforms only by a simple click on APPs installed on a smart phone. When driving with cars, their locations can also be acquired without a...

Members of the macrolide class of antibiotics inhibit peptide elongation on the ribosome by binding close to the peptidyltransferase center and blocking the peptide exit tunnel in the large ribosomal subunit. We have studied the modes of action of the macrolides josamycin, with a 16-membered lactone ring, and erythromycin, with a 14-membered lactone ring, in a cell-free mRNA translation system ...

In this paper, a supply chain network design problem is explained which contains environmental concerns in arcs and nodes of network. It is assumed that there are some routes such as road, rail and etc. in each pair of nodes. In this model decision variables are choosing facilities to open, environmental investment level in each facility and flow of products between nodes in each route. A multi...

To provide safety to users and not disturb traffic flow, autonomous vehicles in shared on-demand mobility services cannot stop everywhere; thus, pick-up drop-off (PUDO) spots must be dedicated or established for them. Our research objective is propose a method locate the PUDO vehicle-based as this topic has been barely studied. The number of required calculated, location chosen considering urba...

OBJECTIVE We previously proposed a simple tool consisting of five items to screen for risk of HIV infection in adolescents (10-19 years) in Zimbabwe. The objective of this study is to validate the performance of this screening tool in children aged 6-15 years attending primary healthcare facilities in Zimbabwe. METHODS Children who had not been previously tested for HIV underwent testing with...
