Opis:: W artykule opisano sposób pomiaru nowej cechy tekstyliów jaką jest rezystancja punktu styku i linii styku dwóch nitek elektroprzewodzących nazwana łącznie rezystancją przejścia. Cecha ta ma kluczowe znaczenie w systemach tekstronicznych łączących technologie włókiennicze z elektronicznymi i informatycznymi. Podano przykładowe wyniki pomiarów przeprowadzonych na unikatowych stanowiskach pomiarowych. Opisano też weryfikację hipotezy o wpływie długości linii styku na wartość rezystancji przejścia.
The paper describes a method for measuring the new feature of textiles, namely the resistance of a contact point and contact line of two electro conductive threads. It is known as a transition resistance. The feature is of special importance in case of textronic systems combining textile, electronic and informatic technologies. The scheme of electroconductive woven fabric and its electrical model is shown. In the structure the contact point resistance is dominant. The contact line resistance is characteristic for knitted structures. They are presented, too, and their electrical model is described. The analysis of the influence of a lap angle of two electro conductive threads on the contact line length was performed. There are also given some results of measurements taken on unique measuring stands. Verification of the hypothesis concerning the influence of the contact line length on the transition resistance value is described. The hypothesis says that when the contact line length increases the line resistance decreases in the lap angle range from 20° to 120°. For the angle value higher than 120° the phenomenon does not exist. The analysis of this phenomenon will be the subject of next investigations.

Opis:: The aim of our study was to evaluate the effectiveness of lurasidone augmentation of clozapine in treatment-resistant schizophrenia (SZ) in a retrospective chart review. From the medical records of 916 SZ patients, we identified 16 individuals treated with a combination of clozapine and lurasidone. The detailed clinical data are described separately for each patient. We compared the Clinical Global Impression—Severity (CGI-S) scores between three points of observation: before the treatment and one month and two months after its initiation. CGI Improvement (CGI-I) scores were used to evaluate the treatment response between the first and last points of observation. The vast majority of patients (14/16, 87.5%) responded to lurasidone augmentation of clozapine (CGI-I scores 1 or 2). Therapeutic effects were observable after 3–12 weeks of treatment (median 6 (4–6)). A reduction in CGI-S scores was observed after the first month of observation. There was an observable reduction in positive, depressive and anxiety symptoms, as well as an improvement in psychosocial functioning. Two patients discontinued treatment due to side effects. Our study suggests that lurasidone augmentation of clozapine may lead to improvements in a broad range of SZ symptom dimensions.

Opis:: Evolving threats to national security have resulted in the adoption of comprehensive (total) defence concepts by a number of small and medium states. Civil resistance constitutes a considerable part of such concepts, complementing military defence. The historical experience of Lithuania proved the value of nonviolent resistance between 1988 and 1991 for regaining independence, and defending it in January 1991. The aim of this article is to analyse the role of non-violent civil resistance in the national defence system, based on the experience of 13 January 1991 in Lithuania and develop further discussion about the concept of civil resistance. The methodological approach of the article is based on historical and theoretical analysis. This allows the experience of Lithuania to be assessed on the basis of Lithuanian National Security and Defence Strategy and scientific research. Lithuanian non-violent civil resistance in 1988–1991 was successful in terms of strategy, leadership, organisation, planning, non-violence priorities and the number of citizens involved. The leaders of the movement were able to mobilise people into a widespread movement based on their moral authority and value orientations, strongly appealing to different groups in society. Lithuania’s independence was achieved with minimal human sacrifice, preserving the country’s resources and infrastructure. This experience of non-violent civil resistance came to be used by modern state institutions to create strategic documents of the state. In the current situation, it is necessary to focus not only on the knowledge required for state defence and civil resistance, but also on its moral aspects such as values, ethical behaviour, civic and human maturity.

Opis:: Zinc is an essential element for all living organisms, but overexposure to this element can have strongly toxic effects. A pot experiment was carried out to evaluate the influence of different zinc concentrations (0, 100, 300, 600, 1200, 2400, 4800 mg Zn2+ kg-1 of soil) on the soil biological activity by analyzing changes in soil stability over time and by determining the resistance (RS) of microorganisms and soil enzyme activity. The influence of Zn2+ on the growth and development of oat and white mustard was evaluated. Overexposure to zinc inhibited the growth of soil microorganisms, the activity of soil enzymes, and the growth and development of plants. Excessive zinc doses cause lower microbial biodiversity and enzyme activity. Bacteria of the genus Azotobacter were most sensitive and spore-forming oligotrophic bacteria were least sensitive to excessive zinc doses. β-glucosidase was most resistant and arylsulfatase was least resistant to the analyzed element. The resistance of the tested microorganisms and enzymes decreased with an increase in zinc accumulation in the soil environment. White mustard was more sensitive to zinc contamination than oat and zinc doses of 2400 and 4800 mg Zn2+ kg-1 led to the death of white mustard plants. The results of this study indicate that soil contamination with zinc poses a threat for living organisms. In areas with a higher risk of zinc deposition, the content of this element in soils should be monitored more frequently than prescribed by environmental protection regulations.

Opis:: The article attempts to systematize the issue of resistance manifestations in the context of education. The analyses presented in the article are an introduction to designing a three-dimensional model of resistance, which enables to exam- ine acts of resistance from the angle of their three intertwined aspects: action, space and motivation. They are basic layers determining the analysis range of particular displays of resistance in education and society. These dimensions were developed based on the analysis of theoretical and empirical literature regarding the issue of resistance and on the author’s own research on this phenomenon.

Opis:: Introduction: Fibromyalgia (FM) is often comorbid with anxiety and depression. Serotonin and noradrenaline reuptake inhibitors (SNRIs) are used in the treatment of FM, depression, and anxiety, but they are ineffective in a substantial number of patients. Recently, it has been reported that FM is associated with impaired glucose metabolism. Objectives: The aim of the study was to explore the associations between insulin resistance, psychiatric comorbidities, and treatment response to SNRIs in patients with FM. Patients and methods: A total of 59 patients with FM and 30 healthy controls (HCs) were recruited. The study patients were classified as treatment-nonresponsive if the SNRI treatment resulted in a reduction in reported pain by less than 30%. All participants were examined by a physician and completed self-report questionnaires. Blood samples were drawn to assess fasting glucose and insulin levels and to calculate the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) values. Multivariable logistic regression models were constructed to analyze the associations between insulin resistance, psychiatric comorbidies, and the lack of response to treatment with SNRIs. Results: The SNRI nonresponders (FM [T–]) had higher body mass index (BMI), fasting insulin level, and HOMA-IR values than the responders (FM [T+]) and HCs. The FM [T+] patients did not significantly differ from HCs in terms of BMI, levels of fasting glucose and fasting insulin, and HOMA-IR values. Depression, anxiety, and personality disorders were significantly more prevalent in the FM [T–] than in the FM [T+] group. Insulin resistance, depression, anxiety, and personality disorders were identified as the predictors of nonresponse to SNRI treatment. The effect of BMI on the lack of response to SNRIs was fully mediated by insulin resistance. Conclusions: Increased values of certain clinical and metabolic parameters (BMI, fasting glucose, fasting insulin, HOMA-IR) as well as the presence of psychiatric comorbidities could affect the response to treatment with SNRIs in the patients with FM.

Opis:: Sintered ferrous components were coated with electrochemical chromium coatings modified with nanodiamond particles. The nanodiamond particles were produced by detonation synthesis with an average grain size 8 nm. The objective of this study was to determine the tribological properties and the corrosion resistance of sintered iron samples coated with an electrochemically deposited chromium layer modified with nanodiamond particles. The thickness of the obtained composite coatings was more than 25 μm. The microstructure and microhardness were determined by metallographic methods. The mechanical and chemical properties of the samples were compared to uncoated samples prepared from the same iron powder. The microhardness was 5 times higher, the wear resistance increased 6 times and the corrosion resistance in 0.1 M NaCl solution was 10 times higher.

Opis:: The results of tests on the brittle fracture and abrasive wear of conical picks sintered carbides taking into account the size of tungsten carbide grains and the content of cobalt are presented. The tests were carried out on the innovative laboratory stand for tribological tests using the method for determination of resistance to edge fracture and abrasive wear. Test results have shown that an increase in the size of tungsten carbide grains, and thus an increase in the cobalt content, reduces the wear resistance and increases the resistance to brittle fracture. The results of the tests of sintered carbides inserts in the aspect of their durability are presented.
