Fundamentals determining activity and product selectivity in the oxidative coupling of methane over MnOx-M2WO4/SiO2 (M=Na, K, Rb, or Cs)

The present thesis contributes to a better understanding of one of the most promising catalysts for the oxidative coupling of methane (OCM) reaction, i.e., MnOx-Na2WO4/SiO2. Oxygen species involved in selective and unselective pathways were investigated using O2 and N2O as the oxidants. Spatially resolved and steady-state kinetic analyses combined with oxygen isotopic exchange tests were used to identify the activity-defining descriptor over M2WO4/SiO2 (M=Na, K, Rb, or Cs). The effects of alkali metal for both bi- and trimetallic compositions on activity and selectivity were establishedDiese Arbeit trägt zu einem besseren Verständnis eines der vielversprechendsten Katalysatoren für die oxidative Kopplung von Methan bei, nämlich MnOx-Na2WO4/SiO2. Unter Verwendung von O2 und N2O als Oxidationsmittel wurden Sauerstoffspezies untersucht, die an selektiven und unselektiven Wegen beteiligt sind. Der aktivitätsbestimmende Deskriptor über M2WO4/SiO2 (M=Na, K, Rb oder Cs) wurde identifiziert. Der Einfluss des Alkalimetalls auf Aktivität und Selektivität für bi- und trimetallische Zusammensetzungen wurden ermittelt

The Impact of the Efficiency of the Judicial System in Attracting Foreign Direct Investments in the Republic of North Macedonia

Foreign direct investment is one of the major factors for the development of national economies with positive implications for the growth of their gross domestic product, technology transfer, as well as increased competitiveness and improved performance of local companies. They generate investment capital, provide new employment, transfer expertise and skills to employees, and increase exports. In the Republic of North Macedonia a number of reform activities have been undertaken relating the protection of property rights, improvement of the efficiency in the functioning of the legislative, judicial and executive branches of government, which result with reduced business risks and motivates companies to make investment decisions. Current paper aimed at outlining the connection between the effectiveness of the judicial system and increasing the number of foreign direct investments in the Republic of North Macedonia

Structure of coenopopulations and phytocoenotic confinement of Paeonia tenuifolia L. in floristic complexes of Oka-Don lowland

Paeonia tenuifolia L. is a rare and protected plant of Saratov region classified as 2 (V) vulnerable species. It has been established that in Kalininsky district, Saratov region, this plant is characterized by narrow environmental amplitude and is exerted to anthropogenic impacts, the coenopopulations are isolated from each other. Existence of the species in communities of the meadow–steppe floristic complexes of Kalininsky district has confirmed that peony is heliophyte, xeromesophyte, eutrophic plant and calcicole. Photophily of P. tenuifoliais confirmed first of all by its high abundance and occurrence in open steppe communities. In both coenopopulations of P.tenuifolia, the indices of recovery have been higher than 1 (CP 1 Irec = 3.38, CP 2 Irec = 1.67), that is, the coenopopulations are relatively steady, numerous seeds are generated giving birth to viable individuals. The index of replacement showing the ratio of the density of regrowth to total mature fraction of the population has been higher in CP 1 (Irepl = 0.80) and lower in CP 2 (Irepl = 0.67). Moderate index of maturing evidence long-term existence of the species in the generative state

Hábitos de consumo e sustentabilidade

Trabalho de Conclusão de Curso (graduação)—Universidade de Brasília, Faculdade de Tecnologia, Departamento de Engenharia de Produção, 2020.Os modelos de produção e os hábitos de consumo da sociedade atual estão entre as principais causas para a contínua depredação do meio-ambiente. Baseado nisso, o presente estudo visa analisar os hábitos de consumo e sua relação com a sustentabilidade. Para tal, foi realizada uma pesquisa aplicada e quantitativa por meio de um questionário composto pela escala ECCB (Comportamento Ecologicamente Consciente do Consumidor), proposta por Roberts (1996). A pesquisa foi realizada com 402 consumidores e os dados foram analisados por meio da utilização do Coeficiente de Correlação de Spearman e do teste t de student (para medir o nível de significância dos coeficientes). Os resultados demonstram que a meditação mindfulness e o nível de escolaridade do indivíduo possuem uma correlação positiva e significativa com os hábitos de consumo sustentáveis, o que impõe a constatação de que a promoção de práticas de mindfulness, assim como investimentos para que os indivíduos aumentem seu nível de escolaridade são medidas que podem auxiliar no desenvolvimento de uma demanda mais sustentável.The production models and consumption habits of today's society are among the main causes for the continued depredation of the environment.

Respiratory Complications from Acute Corrosive Poisonings in Adults

Introduction: Acute corrosive poisonings are caused by ingestion of corrosive chemicals which are most commonly used as household agents. Intoxications with these kind of agents produce numerous and severe post-corrosive complications of the upper gastrointestinal tract. On the other hand, our experience showed that corrosive agents may also cause injuries of the respiratory system, which makes the treatment very hard and additionally complicates the severe clinical condition of the patient. Objective: The aim of the study is to show the incidence of respiratory complications in acute corrosive poisonings, the need of various clinical investigations and also the treatment and final outcome of these kind of poisoning. Methods: We retrospectively analyzed clinical records of 415 patients hospitalized and treated at the University clinic for toxicology and urgent internal medicine, in Skopje, Republic of Macedonia, in the period between 2007 and 2011. The protocol consisted of methods for analyzing the systemic complications, with an accent on the post-corrosive respiratory complications. Results: From the total number of patients even 98 (23.61%) exhibited systemic complications, from which 51 (52.04%) are respiratory complications. The majority of patients are female (n=40, 78.43%) and the most common complication is pneumonia (n=47). The youngest patient in this study was 14 and the oldest was 87 years old. Conclusion: Besides the gastrointestinal complications in the acute corrosive poisonings respiratory complications are also very often. They complicate the clinical state of patient and very often lead to fatal endings

Internal combustion engine sensor network analysis using graph modeling

In recent years there has been a rapid development in technologies for smart monitoring applied to many different areas (e.g. building automation, photovoltaic systems, etc.). An intelligent monitoring system employs multiple sensors distributed within a network to extract useful information for decision-making. The management and the analysis of the raw data derived from the sensor network includes a number of specific challenges still unresolved, related to the different communication standards, the heterogeneous structure and the huge volume of data. In this paper we propose to apply a method based on complex network theory, to evaluate the performance of an Internal Combustion Engine. Data are gathered from the OBD sensor subset and from the emission analyzer. The method provides for the graph modeling of the sensor network, where the nodes are represented by the sensors and the edge are evaluated with non-linear statistical correlation functions applied to the time series pairs. The resulting functional graph is then analyzed with the topological metrics of the network, to define characteristic proprieties representing useful indicator for the maintenance and diagnosis

Heroin dependents are insulin resistant

Background. Fasting insulin levels, HOMA-IR and HOMA-%B are precise methods for determining insulin resistance and can be used in assessing the insulin sensitivity in heroin dependents (HD). Heroin dependents are expected to be insulin resistant. To determine the heroin influence on insulin sensitivity in male heroin dependents compared to control healthy male (K). Materials. Fasting insulin levels (I), HOMA-IR, HOMA-%B, fasting glucose levels (gl) and C-peptide (C) were determined in both groups, group K with mean age (28.1±4.2 yr) and mean BMI (22.8±2.5 kg/m2), not different compared to group HD with mean age (27.9±5.4 yr) and BMI (22.3±3.1 kg/m2),which were HCV negative. Methods. I and C were determined with hemiluminiscentmethod on Immunology Analyzer Immulate2000, HOMA-IR was calculated [(FIxFgl)/22.5], as well as HOMA-%B [(20xFI)/(Fgl-3.5)]. Results. I values in HD group were 15.24±27.6 IU/L, significantly higher compared to K (4.58±3.23) (p0.05). HOMA-IR in HD (2.52±3.29) and HOMA-%B (111.56±58.14) were significantly higher compared to the correspondent values in K (1.02±0.8) (p<0.016) and (68.83±46.57) (p<0.05). I values correlated highly significantly positively with HOMA-IR, HOMA-%B and C-peptide (p<0.0001) in HD. Conclusions. HD were characterized with significantly higher I, HOMA-IR, HOMA-%B values, which correlated highly significantly between themselves, confirming insulin resistance in HD
