A one-step synthesis of [1,6]naphthyridine-2(1H)-thione (3a), pyrano[3,4-b]pyridine-2(1H)- thione (3b), thiopyrano[3,4-b]pyridine-2(1H)-thione (3c) and 6-oxoquinoline-2(1H)-thione (3d) through the reaction of benzylidene-cyanothioacetamide (1) with cyclic ketones 2a−d is described. The reaction of 3a−d with organyl chlorides yielded the 2-alkylthio-3-cyanopyridines 4a−p which upon refluxing in ethanolic sodium ethoxide afforded the thieno[2,3-b]pyridine derivatives 5a−n. Some of the synthesized compounds were screened for the activity against bacteria and fungi.

Abstract Quaternary ammonium biocides are commonly used in cooling water systems to control organisms associated with microbiologically induced corrosion and microbial fouling.

Full text
Abstract:
An initial series of experiments was conducted in thin wall pipe [(0.125 to 0.188 in. (3.2 to 4.8 mm)] to investigate the effect of pressure and welding direction on the risk of burnthrough.� A second series of experiments was conducted to investigate the effect of other welding variables, including electrode angle, electrode polarity, and welding against the edge of a full-encirclement sleeve.� The third series of experiments concentrated on developing limits for welding onto in-service pipelines thinner than 0.125 in. (3.2 mm).�

Full text
Abstract:
This paper focuses on the performance of IDB projects between 1996 and 2011 disbursements. We present evidence on the evolution of disbursements with respect to the available funds and the evolution of disbursements with respect to the historic disbursement curve of IDB projects. We also identify the main factors driving disbursements. Our findings show that disbursements improved in the last 10 years; in particular, they improved after the organizational changes instituted after 2006. With respect to the factors driving disbursements, we find that: (i) Country is more important than sector in

Abstract:
When the technology and policy communities use terms associated with trustworthy AI, could they be talking past one another? This paper examines the use of trustworthy AI keywords and the potential for an “Inigo Montoya problem” in trustworthy AI, inspired by "The Princess Bride" movie quote: “You keep using that word. I do not think it means what you think it means.”
