Modeling and simulation of heat production in a local heating installation including a batch-fired straw boiler with a buffer tank.

The paper presents the problem of modeling and simulation of thermal energy generation in a batch-fired straw boiler combined with a buffer tank. The batch-fired straw boiler in concern have a combustion chamber and a water jacket. During the combustion process, the combustion chamber heats up and from it the water jacket.

Shortening the decade-long gap between adult and paediatric drug formulations: a new framework based on the HIV experience in low- and middle-income countries.

Introduction: Despite the coordinated efforts by several stakeholders to speed up access to HIV treatment for children, development of optimal paediatric formulations still lags 8 to 10 years behind that of adults, due mainly to lack of market incentives and technical complexities in manufacturing. The small and fragmented paediatric market also hinders launch and uptake of new formulations. Moreover, the problems affecting HIV similarly affect other disease areas where development and introduction of optimal paediatric formulations is even slower.

Cervical wet mount as a negative predictor for gonococci- and Chlamydia trachomatis-induced cervicitis in a gravid population.

Objective: The purpose of this study was to determine whether a wet mount preparation of endocervical secretions from obstetric patients can accurately rule out the presence of gonococci and Chlamydia trachomatis.

Study Design: Gravid patients were screened for gonococci and C trachomatis with a deoxyribonucleic acid probe and a wet mount preparation of endocervical secretions. The number of polymorphonuclear lymphocytes was counted and averaged per x400 high-power field.

Action of organophosphates on the electroretinogram of rainbow trout.

Electroretinograms (ERGs) were recorded in vitro from eyes of rainbow trout that had received intraperitoneal injections of either TOCP (triorthocresyl phosphate) or DEF (S, S, S-tributyl phosphorotrithioate). Data obtained after 24 h indicated that these organophosphates caused alterations in four of five ERG parameters in the case of TOCP and all five parameters in the DEF treated specimens. These data were compared with data obtained from experiments with eserine and carbachol and led to the conclusion that the effects of the organophosphates on the retina were independent of any cholinesterase inhibitor activity of the compounds.
