Плазменное получение тепловой энергии из сульфатного лигнина
This article shows an overview and analysis of the literature on methods of using sludge lignin. This product obtained after treatment of pulp. As a result of calculating the optimum composition of water, organic materials with mechanical impurities from the adiabatic combustion temperature of about 1200 K were determined. Using the obtained results of experimental studies have been carried out in a plasma reactor of the catalytic reactor and has been optimized. The obtained results can be used to create industrial enterprises based on plasma catalytic reactors for waste sludge lignin for the purpose of obtaining heat

Relevance of genetic testing in the gene-targeted trial era: the Rostock Parkinsons disease study.
Estimates of the spectrum and frequency of pathogenic variants in Parkinsons disease (PD) in different populations are currently limited and biased. Furthermore, although therapeutic modification of several genetic targets has reached the clinical trial stage, a major obstacle in conducting these trials is that PD patients are largely unaware of their genetic status and, therefore, cannot be recruited. Expanding the number of investigated PD-related genes and including genes related to disorders with overlapping clinical features in large, well-phenotyped PD patient groups is a prerequisite for capturing the full variant spectrum underlying PD and for stratifying and prioritizing patients for gene-targeted clinical trials. The Rostock Parkinsons disease (ROPAD) study is an observational clinical study aiming to determine the frequency and spectrum of genetic variants contributing to PD in a large international cohort. We investigated variants in 50 genes with either an established relevance for PD or possible phenotypic overlap in a group of 12 580 PD patients from 16 countries [62.3% male; 92.0% White; 27.0% positive family history (FH+), median age at onset (AAO) 59 years] using a next-generation sequencing panel. Altogether, in 1864 (14.8%) ROPAD participants (58.1% male; 91.0% White, 35.5% FH+, median AAO 55 years), a PD-relevant genetic test (PDGT) was positive based on GBA1 risk variants (10.4%) or pathogenic/likely pathogenic variants in LRRK2 (2.9%), PRKN (0.9%), SNCA (0.2%) or PINK1 (0.1%) or a combination of two genetic findings in two genes (∼0.2%). Of note, the adjusted positive PDGT fraction, i.e. the fraction of positive PDGTs per country weighted by the fraction of the population of the world that they represent, was 14.5%. Positive PDGTs were identified in 19.9% of patients with an AAO ≤ 50 years, in 19.5% of patients with FH+ and in 26.9% with an AAO ≤ 50 years and FH+. In comparison to the idiopathic PD group (6846 patients with benign variants), the positive PDGT group had a significantly lower AAO (4 years, P = 9 × 10-34). The probability of a positive PDGT decreased by 3% with every additional AAO year (P = 1 × 10-35). Female patients were 22% more likely to have a positive PDGT (P = 3 × 10-4), and for individuals with FH+ this likelihood was 55% higher (P = 1 × 10-14). About 0.8% of the ROPAD participants had positive genetic testing findings in parkinsonism-, dystonia/dyskinesia- or dementia-related genes. In the emerging era of gene-targeted PD clinical trials, our finding that ∼15% of patients harbour potentially actionable genetic variants offers an important prospect to affected individuals and their families and underlines the need for genetic testing in PD patients. Thus, the insights from the ROPAD study allow for data-driven, differential genetic counselling across the spectrum of different AAOs and family histories and promote a possible policy change in the application of genetic testing as a routine part of patient evaluation and care in PD
Customer Satisfaction with Alpine Ski Areas: The Moderating Effects of Personal, Situational, and Product Factors
In highly competitive markets, customer satisfaction is a key driver of performance, making its measurement and management crucial. Most studies on customer satisfaction take an aggregate standpoint and do not consider segment-specific differences in attribute importance. In this article, the authors report on customer satisfaction with alpine ski resorts. They hypothesize that personal, situational, and product factors moderate the relationship between attribute performance and overall satisfaction. The results show that these factors indeed influence the attribute–performance–satisfaction relationship. Theoretical and managerial implications of these findings are discussed
Treatment of postinfectious olfactory disorders with minocycline: A double-blind, placebo-controlled study
Personality traits and knowledge sharing
In this paper, we describe an empirical study that relates three personality traits (agreeableness, conscientiousness and openness) to knowledge sharing. In the existing literature considerable attention has been paid to managerial influences on knowledge sharing, technological support through information and communication systems, or individual characteristics like motivation or the perception of conflict of interest or vulnerability. Instead we concentrate on the role that personal dispositions play in individual's knowledge sharing behavior. By means of structural equation modeling with PLS, we discover significant correlations between the personality traits and knowledge sharing within teams of an engineering company. Our results clearly contribute to the existing literature, as they offer empirical evidence of the impact of enduring individual characteristics on knowledge sharing.
