In recent years, one in every eight Poles has been involved in a road traffic accident. In the aftermath, many are affected by symptoms described by psychologists and psychiatrists as posttraumatic stress disorder (PTSD). Psychologists study the mental wellbeing of people who have been involved in such accidents, and also provide therapies helping them resume their normal activities.

The studied collecting electrodes for electrostatic precipitators are cold-rolled formed. Here Sigma 750 open section was manufactured of DC01 steel grade. Length of the electrodes ranged from 8 to 13 meters, all were thin-walled of 1.5 mm. Tolerance of their manufacture is strictly set. A database of material properties, chemical composition, and a set of final tolerance of manufactured profiles has been collected. At first basic statistics for the data has been done. Finally statistical relation between the material composition and profile geometrical tolerance has been studied, next between the material mechanical properties and profile geometrical tolerance has been examined.

Detection of explosives vapors is an extremely difficult task. The sensitivity of currently constructed detectors is often insufficient. The paper presents a description of an explosive vapors concentrator that improves the detection limit of some explosives detectors. These detectors have been developed at the Institute of Optoelectronics. The concentrator is especially dedicated to operate with nitrogen oxide detectors. Preliminary measurements show that using the concentrator, the recorded amount of nitrogen dioxide released from a 0.5 ng sample of TNT increases by a factor of approx. 20. In the concentrator an induction heater is applied. Thanks to this and because of the miniaturization of the container with an adsorbing material (approx. 1 cm3), an extremely high rate of temperature growth is achieved (up to 500 °C within approx. 25 s). The concentration process is controlled by a microcontroller. Compact construction and battery power supply provide a possibility of using the concentrator as a portable device.

Psychoterapia jako praktyka kliniczna oparta na danych naukowych jest stosunkowo młodą dziedziną. Definiując psychoterapię, zarysujemy kontinuum – od zastosowania metod psychologicznych do poprawy dobrostanu, do psychoterapii jako metody leczenia zaburzeń psychicznych wspartej badaniami empirycznymi. Omawiamy rodzaje badań nad skutecznością, tworzenie zaleceń dla praktyki. Na przykładzie prowadzonych w Polsce badań nad psychoterapią i farmakoterapią PTSD wskażemy na ważne pytania współczesnej psychoterapii dotyczące interpretacji wyników badań, bezpieczeństwa pacjenta, personalizacji leczenia i dróg rozwoju, ale też miejsca w systemie opieki zdrowotnej.

W ostatnich latach co ósmy Polak był uczestnikiem różnego rodzaju wypadków drogowych. Dla wielu jest to doświadczenie wywołujące zaburzenia opisane przez psychologów i psychiatrów jako PTSD - pourazowe zaburzenie stresowe. Psychologowie nie tylko badają stan uczestników wypadków, lecz także stosują terapie umożliwiające im powrót do normalnego życia.

The paper deals with the problem of production material flow management. The proper way of logistic tasks management has an impact on the production process effectiveness and the cycle time, which is a very important factor in manufacturing. Reducing the production process cycle time results not only in the ability to provide more customers with orders but also in increasing the level of resources usage (machines, operators etc.). In order to reach the aim of improving production effectiveness, the simulation modeling was used. It is a computer method that supports a decision-making process and allows to perform experiments on production without interfering with the real process. The paper also includes a risk analysis performed to evaluate the imperfections of simulation modeling, based on the rules of fuzzy logic.

Atopic dermatitis (AD) is the most frequent allergic disease in dogs. AD can be treated using allergenspecific immunotherapy as well as symptomatic antipruritic treatment including the use of lokivetmab - caninized anti-interleukine-31 antibody.

The aim of the study was to evaluate the effectiveness of lokivetmab over 12 weeks of treatment. Studies have been carried out in 89 dogs. In all affected animals, the severity of lesions was assessed using the CADESI 04 and the pruritus was assessed using the VAS.

After the first dose of lokivetmab, both CADESI 04 and VAS statistical decreased by 4 weeks from 40.48 to 20.31, and from 7.42 to 2.48, respectively (p = 0.0000001) maintained significantly decresed values during the whole treatment period (CADESI 04 15.64, 15.07 after 8 and 12 weeks, respectively, PVAS 2.03, 1.95 after 8 and 12 weeks, respectively).

Lokivetmab leads to a significant reduction of CADESI 04 and pruritus, within four weeks and maximum effect is achived after the second dose.
