Towards the electrochemical conversion of CO2 to formic acid at an applicative scale: technical and economic analysis of most promising routes

In the last decade, the electrochemical conversion of CO 2 to formic acid, FA, using Sn\u2010based cathodes, was widely investigated. In this work, the technical feasibility and economic viability of this process were evaluated considering the most promising electrochemical routes reported in the literature. Five case studies, based on the utilisation of GDE technologies or high CO 2 pressures, were analysed. The cost for producing FA by the electrochemical route was compared with that of the conventional chemical route. Several scenarios were envisioned finding the target figures of merit, the potential bottlenecks (including low FA concentration, GDE cost and high energy consumption) of each technology and the challenges that need to be faced. It was shown that the performances of these processes are not still adequate from an economic point of view and the improvements that should be achieved were identified. To be suitable for the commercialisation, the process should reach simultaneously high current density, faradaic efficiency and actual FA concentration as well as good stability with time and a limited cost of electrodes. In addition, it was shown that the utilisation of the excess electric energy generated from renewable sources could significantly reduce the costs of the process

My future thesis investigates the aspects of communication regarding waste management. I analyse the factors that may influence social consciousness in the long run and what communication tools opinion leaders can use to reach out to the various social platforms

Effect of Selenium on HLA-DR Expression of Thyrocytes

Autoimmune thyroid diseases (ATDs) represent the most frequent forms of the organ-specific autoimmune thyroid disorders that result from interaction between genetic and environmental factors. Selenium has been shown to exert a beneficial effect on the autoimmune thyroiditis. In spite of therapeutical effect of selenium on autoimmunity, the mechanism of its action has not been revealed. Objective. To determine whether selenium in vitro thyrocytes cultures are able to influence the HLA-DR molecule expression of human thyrocytes and production of free oxygen radicals. Method. Thyrocytes were prepared from human thyroid gland and cultured in vitro in the presence of interferon-γ and sodium selenite. The expression of HLA-DR molecules induced by interferon-γ in the presence of sodium selenite of various concentration was measured by fluorescence-activated cell sorter. Results. Selenium has a dose-dependent inhibitory effect on the expression of HLA-DR molecules of thyrocytes induced by interferon-γ. This effect of selenium was in the inverse correlation with antioxidative capacity. Conclusion. Beneficial effect of selenium on autoimmune mechanism is a complex mechanism in which the inhibitory effect on HLA-DR molecule expression and antioxidative capacity are involved into therapy of autoimmune thyroiditis

Népesedési világnap – Java EE esettanulmány: World Population Day – Java EE case study

In 1987 the United Nations declared July 11 to be World Population Day. The population of our planet reached 5 billion that day. On the worldometer.info website, regularly updated reports are available to the population globally, by region, by country. We start from a Java SE project and develop it into a Java EE project. In the process, we use an object-oriented approach, MVC architectural design pattern. The completed case study is a distributed Java project that displays population in specified regions from 1950 to the current year based on data collected from the web. The article describes the specification, the development/planning steps, the implementation and presents the result.

Culture and Climate of Safety in Organizations: Conceptualizations and Assessment

The concepts of safety culture and safety climate have received a great deal of attention from safety professionals and academic researchers as efficient non-technological means of reducing injuries and accidents within various industries. However, there is conceptual confusion regarding these constructs as there is a lack of single, unified theoretical and operational definitions for both of these constructs, which has led to a vast number of assessment tools with questionable validity and applicability. In this thesis, the author addressed some of these conceptual issues. The thesis reports two studies. In Study one, the author conducted a conceptual analysis of the two constructs, which included analysis of theoretical definitions of safety culture and safety climate, analysis of their operational definitions, and assessment of congruency between these types of definitions. Finally, a theoretical definition and an operational definition was developed and presented for each of these constructs. This conceptual analysis was complemented by the analysis of corresponding literature. In Study two, the researcher focused on developing and verifying a self-report measure for assessing safety climate in the College of Engineering. The developed theoretical and operational definitions for safety climate were used to develop the Saskatchewan Safety Climate Questionnaire. This questionnaire was administered to 267 students in the College of Engineering at a Canadian University. The developed Safety Climate Questionnaire demonstrated adequate psychometric properties and highlighted the link between safety climate and students’ experience with injuries and near misses on campus. The safety climate scores were found to be related to students’ discipline, previous work experience in industry, students’ experience with injuries and near misses, and witnessing injuries and near misses

A Basedow-Graves kór immunológiai és molekuláris genetikai vizsgálata = Immunological and molecular genetic investigation of Graves' disease

A szolubilis CD4 (sCD4) molekulák szintjét határozták meg a terhesség alatt és után azokban a nőkben, akik korábban post-partum thyreoiditsben (PPT-ben ) szenvedtek Kimutatták, hogy ha az anya dohányzott vagy fiú gyermeket szült, akkor a PPT recidivája gyakoribb és a sCD4 szint élettani csökkenésének elmaradása jó indikátora a betegség recidivájának. Prospektiv, randomizált vizsgálatot végeztek, amelyben összehason-lították a metimazol (MMI)+ placebo és a MMI+ pentoxifillin (Ptx) hatását a pajzsmirigybetegséghez társult orbitopathia (TAO) kialakulásában. Kimutatták, hogy a dohányzás növelte a TAO rizikóját. A Ptx kezelés jelentősen gátolta a TAO manifesztációját, ezért javasolt alkalmazása a dohányzási szokást abbahagyni nem képes betegeknek. A Basedow-Graves kór csak az emberben megfigyelt autoimmun betegség, amelynek kialakulásában felvetődött a TSH-receptornak (TSH-R-nak) az állatoktól eltérő genetikai polimorfizmusa. A szerzők ezért szekvenálták az ember és két majom törzs, a M. mulatta és a C. aetiops TSH-R génjét. Mindkét törzs génjei 764 aminosavat kódoltak, a szerkezeti homológia a két állat receptora között 99%-os, a C. aetiops , ill. a M mulatta és az ember között 97 és 96%-os volt. A receptor ektodoménjének C-terminális és intracelluláris szekvenciái mutatták a legnagyobb varianciát. Megállapították, hogy a TSH-R-nak a főemlősöktől eltérő struktúrája nem felelős a BG kór kizárólagosan az emberre vonatkozó manifesztációjáért. | The soluble CD4 and CD8 molecules during and after pregnancies in women who had been suffered from post-partum thyroiditis (PPT). The risk of relapse of thyroiditis was increased in patients with smoking habit or if their children were boys. It was concluded that the loss of physiological decrease in soluble CD4 concentration is an indicator of relapse of thyroiditis. Prospective, randomized study was made for comparing the influence of methimazole (MMI) + placebo and MMI + pentoxiphylline (Ptx) with respect to grades of thyroid associated orbitopathy.(TAO). Smoking by itself without genetic factors greatly increased the risk of orbitopathy. If the smoking habit was associated with genetic background, the manifestation of orbitopathy significantly increased. Ptx therapy had a beneficial preventive effect on manifestation of eye symptoms. To test human specificity of Graves? disease, we sequenced the TSHR gene of two monkey species M. mulatta and C. aethiops.. Both genes encoded a protein of 764 residues. This structure was 99% homologous between the two species while C.aethiops was 97 % and M mulatta 96% homologous to H. sapiens. The most variable sequences were those of the intracellular tail and the distal cysteine-rich C-terminus flanking region. of the ectodomain. There was not found specific region of TSH- receptor which migh be responsable of autoimmunity in human thyroid disease included Graves'disease
