Published: April 2019

The results of research on the electrochemical processing of acidic regeneration solutions containing heavy metals ions are presented. The use of a three-cell electrolyzer makes it possible to efficiently extract zinc, copper and nickel ions from muriatic solutions and to concentrate hydrochloric acid in the cell’s intermediate chamber. The paper studies the dependence of the current yield of heavy metals on the concentration of hydrochloric acid, the initial concentration of heavy metals in the cathode chamber, the duration of electrolysis and the concentration of hydrochloric acid in its concentrating zone. The yield of copper and zinc decreases with increasing of acidity in the initial solutions and in the intermediate chamber of the cell. The current yield of nickel is determined to be little depended on the initial concentration of hydrochloric acid. The results on the concentration of hydrochloric acid, depending on the duration of electrolysis, the initial concentration of acid and heavy metals in the catholyte are presented. Bibl. 9, Fig. 9.
REVIEW OF TECHNOLOGIES FOR REDUCING OF NITROGEN OXIDES EMISSIONS ON COAL-FIRED POWER PLANTS
Authors: Kolomiets O.M.
Published: April 2019

The paper discusses the technologies of reducing the concentration of nitrogen oxides in the exhaust flue gases during the combustion of coal in the boiler units of power plants that produce heat and electrical energy. According to the results of the analysis, the influence of the method of oxidizing gaseous nitrogen oxides on the efficiency of the treatment plant was revealed. It has been established that during the reconstruction of the gas cleaning system, the advantage is in the technology in which, at the first stage, a gaseous oxidizer is added to the gas flow to convert nitric oxide into heavier water-soluble compounds. At the second stage, an aqueous solution of alkali metal compounds or ammonia is injected into the gas mixture for chemical bonding of the products of oxidation reactions. Thus, this technology allows reducing the concentration of nitrogen oxides in flue gases by 90–95% and meeting the requirements of regulatory documents on emissions of pollutants into the environment.

CONDITIONS OF MINIMAL LOSS OF EXERGY IN NON-EQUILIBRIUM PROCESSES OF ACTUATING MEDIUMS HEAT EXCHANGE
Authors: Bondar V.P.
Published: April 2019

Heat exchange of actuating mediums in heat-exchanging apparatuses runs non-equilibrium (irreversibly), causing loss of operational part of heat. Two types of non-equilibrium process are distinguished: external and internal. External irreversibility is function of average temperature difference (irreversibility degree) and relation of incomplete recuperation on heat exchange boards of actuating mediums. Nature of internal non-equilibrium processes is related to friction work of actuating mediums that are practically impossible to be taken into account and described analytically. In this article, in order to define conditions of change of current temperature difference by exponential law, external and internal irreversibility are reviewed both mutual and separately. Change of current temperature difference by exponent is one of conditions of minimal numeric value of entropy production of system in non-equilibrium processes of actuating mediums heat exchange existence. Analysis, performed in article, along with example, are evidence that at all types of irreversible processes of actuating mediums heat-exchange, exist conditions of gaining the numeric value of minimum entropy production and exergy losses.

Authors: Bilousova N.A. , Herasymenko Yu.S. , Red’ko R.M. , Yatsishina N.Yu.
Published: April 2019

The processes of scale formation and corrosion on the surface of heat exchange using ultrasound with a frequency of 26.5 kHz of low power in the provisional and transient modes and without it were studied. The functional dependences of the build-up of the specific mass of the scale and the corrosion rate are established, depending on the ultrasonic irradiation regimes. The morphology and structure of the scaled layers formed by the scanning electron microscopy method are studied. It has been established that ultrasonic treatment of low intensity promotes the formation and maintenance of a phase microlayer with anticorrosion properties, which practically does not reduce the heat exhange between the metal surface and the coolant.

Published: April 2019

Objective: analysis and summary of the literature data and own studies on the possibility of using biomarkers of exposure and effect of organophosphorus compounds (OPCs), determination of immunological biomarkers of the effect under exposure to OPCs that cause delayed neurotoxicity (DN). Materials and Methods. Analytical methods were used in the work: collection of scientific information on the topic, analysis of data and scientific summary of the results. Re-assessment of the effect of OPCs causing DN was performed from the perspective of determination of the most informative immunological biomarkers of the effect of known neurotoxicants. Analysis of the study results of the effect of neurotoxic OPCs, triorthocresyl phosphate (TOCP), Afos on the immune system was performed using the most sensitive model — chicken breed Leghorn in isotoxic doses (500 mg/kg and 200 mg/kg, respectively) using common immunotoxicology methods. Results and Conclusions. The article analyses and concludes current literary data on the justified use of biomarkers of exposure and effect of OPCs that are widespread in the environmental objects and are one of the reasons of acute and chronic poisoning in the population. We’ve reviewed aspects of the necessity for implementation of scientifically justified approach to the development and assessment of biomarkers and creation of the unified diagnostic complex that includes biomarkers of exposure, specific and non-specific action, with wider diagnostic abilities compared with determination of isolated parameters that is the basis for diagnostics, efficient treatment and prediction of consequences of poisoning with OPCs. Based on the results of own studies, we proposed the use of some parameters as the immunological biomarkers of the effect of OPCs with DN: the level of finely dispersed circulating immune complexes in the blood serum and the level of anti-brain antibodies, the number and functional activity of blood neutrophils; the number of T-and B-lymphocytes and their functional activity; the number of NK-cells, T-helper cells, and T-suppressors.
Australian Gonococcal Surveillance Programme Annual Report, 2017
Authors: Lahra Monica M , Enriquez Rodney , George C. R. Robert
Published: April 2019

The Australian Gonococcal Surveillance Programme (AGSP) has continuously monitored antimicrobial resistance in clinical isolates of Neisseria gonorrhoeae from all states and territories since 1981. In 2017, there were 7,835 clinical isolates of gonococci from public and private sector sources tested for in vitro antimicrobial susceptibility by standardised methods. Current treatment recommendations for gonorrhoea for the majority of Australia, is a dual therapeutic strategy of ceftriaxone and azithromycin. Decreased susceptibility to ceftriaxone (Minimum Inhibitory Concentration or MIC value 0.06-0.125 mg/L) was found nationally in 1.06% of isolates, which is lower than that reported in the AGSP Annual Report 2016 (1.7%). The highest proportions were reported from Victoria and Western Australia (urban and rural) (2.1% and 1.4% respectively). Resistance to azithromycin (MIC value ≥1.0 mg/L) was found nationally in 9.3% of isolates, which is approximately double the proportion reported in 2016 (5.0%) and more than three times the proportion reported in 2015 (2.6%). The highest proportions were reported from Victoria (13.5%), South Australia (12.8%) and New South Wales (9.3%). High level resistance to azithromycin (MIC value ≥256 mg/L) was reported in 4 strains nationally in 2017, 2 from Victoria, one from New South Wales, and one from Queensland.
The proportion of strains resistant to penicillin in non-remote Australia ranged from 10.3% in non-remote Northern Territory to 44.1% in Tasmania. In remote Northern Territory, penicillin resistance rates remain low (2.5%). In remote Western Australia, penicillin resistance rates continue to increase (6.7%) compared to the previous years, however, there were relatively low numbers of strains available for isolate based testing (n=12). To address this and to monitor resistance and inform treatment guidelines, widespread molecular testing for penicillin resistance in Western Australia is in place, and these data are included in the AGSP.
The proportion of strains resistant to ciprofloxacin in non-remote Australia ranged from 17.2% in non-remote Northern Territory to 61% in Tasmania. Ciprofloxacin resistance rates remain comparatively low in remote Northern Territory (1.3%) and remote Western Australia (5.0%).

Authors: Yang Ying-Ying , Shulruf Boaz
Published: April 2019

Purpose: Lack of confidence in suturing/ligature skills due to insufficient practice and assessments is common among novice Chinese medical interns. This study aimed to improve the skill acquisition of medical interns through a new intervention program. Methods: In addition to regular clinical training, expert-led or expert-led plus artificial intelligence (AI) system tutoring courses were implemented during the first 2 weeks of the surgical block. Interns could voluntarily join the regular (no additional tutoring), expert-led tutoring, or expert-led+AI tutoring groups freely. In the regular group, interns (n=25) did not receive additional tutoring. The expert-led group received 3-hour expert-led tutoring and in-training formative assessments after 2 practice sessions. After a similar expert-led course, the expert-led+AI group (n=23) practiced and assessed their skills on an AI system. Through a comparison with the internal standard, the system automatically recorded and evaluated every intern’s suturing/ligature skills. In the expert-led+AI group, performance and confidence were compared between interns who participated in 1, 2, or 3 AI practice sessions.Results: The end-of-surgical block objective structured clinical examination (OSCE) performance and self-assessed confidence in suturing/ligature skills were highest in the expert-led+AI group. In comparison with the expert-led group, the expert-led+AI group showed similar performance in the in-training assessment and greater improvement in the end-of-surgical block OSCE. In the expert-led+AI group, the best performance and highest post-OSCE confidence were noted in those who engaged in 3 AI practice sessions.Conclusion: This pilot study demonstrated the potential value of incorporating an additional expert-led+AI system–assisted tutoring course into the regular surgical curriculum.
