In an attempt to prepare the tris(selenoureato)gallium(III) complex [Ga(4-O2NC6H4C(O)NC(Se)NEt2)3] from the reaction of the nitro-substituted acylselenourea 4-O2NC6H4C(O)NHC(Se)NEt2 with [Ga(NO3)3] in EtOH we obtained a crystalline compound from a CH2Cl2 solution which was identified as the bis(selenoureato)gallium(III)chlorido complex [GaCl(4O2NC6H4C(O)NC(Se)NEt2)2] by single-crystal X-ray dif...

Failure was not an option. We had a very short time to make an important application perform very much better. Obviously we couldn’t do a complete rewrite. However, we were fortunate enough to have use of a full-sized server to test some tuning strategies. Thorough research into best practices around OS buffering and filesystem alternatives turned up some simple hypotheses to test. Once we set ...

Objectives: This article systematically reviews the state of the art of the ‘‘hot hand’’ research in sports. The belief that successive attempts of an individual player are positively related, as well as the behavior influenced by such a belief, will be investigated. Method: The analysis of experiments, simulations, and archival data from actual sport competitions are structured in a way that e...

An efficient solvent free reaction of 1-chloro-2-nitrobenzene with anilines to give N-substituted nitro anilines by nucleophilic aromatic substitution in good to excellent yields has been described. The effect of different salts on the reaction has also been studied.

Crabs are renowned for their cranky demeanor, but when one considers the extreme conditions under which they must survive, it becomes easier to sympathize with these crotchety crustaceans. One hardship that crabs must endure is changing temperature: a daily swing of 20°C is not unusual for the intertidal zone. Because crabs do not actively maintain a constant internal body temperature, environm...

Just how “hot” is the topic of conflict of interest in psychiatry? The answer was brought home to me dramatically this past May at the APA meeting in Toronto. During the meeting, I had the opportunity to chair a symposium titled “Pharmaceutical Industry Influence in Psychiatry.” My copresenters and I showed up well ahead of time to meet and prepare introductions. As we gazed out at the empty se...

The purpose of this study is to develop HOT (Higher Order Thinking) Lab–based practicum guide that improves pre-service physics teachers’ creative thinking skills. The research method used 3D-1I model (Define, Design, Develop and Implementation). The subjects of this study are 40 students of Physics Education Program UIN Sunan Gunung Djati Bandung. The results showed that the HOT Lab-based prac...

Ten imidazole derivatives were tested for mutagenicity in Salmonella typhimurium strains TA98 and TA100 both in the absence and presence of metabolic activation by the microsomal fraction S9 mix. In a general manner, derivatives tested exhibited a greater mutagenic activity in the TA100 strain comparing to the responses in TA 98. In the standard plate incorporation assay, 8 of these substances ...

In the present study, an appropriate synthetic route was adopted to produce the target synthesis of Juglone. In the first of these objectives, 5-nitro-1,4-naphthoquinone had been synthesized by direct nitration of 1,4-naphthoquinone in the presence of water and sulfuric acid. Then the intermediate synthesis of 5-amino-1,4-naphthoquinone was obtained by the reduction of nitro. Finally, Juglone w...
