Opis:
Listening tests have been carried out to quantify the significance of binaural auralization over monaural auralization in accordance with the acoustic properties of the enclosure. To this end, acoustic rendering of three different rooms were generated based on synthesized monaural (two channels with the same audio material) and binaural room impulse responses. The auralizations were evaluated by means of subjective tests using headphones with non-individualized equalization. Parameters, such as localization, spatial impression and realism, were taken into consideration to determine the relevance of providing binaural information for the auralization of a given room. The analysis of the data has been conducted following a statistical approach based on ANOVA and Pearson correlation. The results indicate that spatial perception is strongly dependent on the acoustic characteristics of the rooms and on the listening condition of the audio material. Furthermore, as expected, advantages of binaural rendering in terms of source localization was also confirmed.

Opis:
In the paper apossibility of using ametrology micro computed tomography (CT) to assess quality of parts made by rapid prototyping technique was presented. Additive manufacturing techniques dramatically change the approach to manufacturing process. Not long ago they allowed solely for obtaining aspatial model of apart in order to visualize its features. Nowadays, it is possible to produce elements and assembly groups with properties that make it possible to replace many parts manufactured using traditional casting or injection techniques. Polymer components created by means of 3D printing can be generated one layer of material after another. In many cases inner spaces (sections) are not fully filled in (solid), they are rather replaced by aspecially selected structure. Thanks to this it is possible to save material and reduce weight. To control these structures and to inspect joints between particular layers using anon-destructive method it is necessary to use ametrology micro CT. In the paper an application of X-ray computed tomography and assessment of measurement uncertainty regarding elements manufactured with fused deposition modeling (FDM) method using ABS 3D printing on UP! printer was presented. Inspection of both: inner structure and outer shapes as well as joints between them was performed basing on computer aided design (CAD) model.
W pracy przedstawiono możliwość zastosowania pomiarowej tomografii komputerowej (CT) do oceny jakości elementów wykonanych techniką szybkiego prototypowania. Techniki wytwarzania addytywnego rewolucjonizują podejście do technik wytwarzania. Jeszcze niedawno pozwalały jedynie na uzyskanie przestrzennego modelu w celu jego wizualizacji. Obecnie możliwe jest uzyskanie gotowych elementów o właściwościach pozwalających na zastąpienie wielu wyrobów wykonywanych tradycyjnymi technikami odlewania lub wtryskiwania. Elementy polimerowe uzyskiwane za pomocą druku 3D wytwarzane są przez nakładanie kolejnych warstw materiału. W wielu wypadkach wewnętrzne przestrzenie (przekroje) elementu nie są całkowicie wypełnione, ale są zastępowane przez odpowiednio dobraną strukturę wewnętrzną. Pozwala to na oszczędność materiału i redukcję masy elementów. Kontrola jakości tych struktur, jak i połączeń pomiędzy poszczególnymi warstwami, jest możliwa w sposób nieniszczący jedynie za pomocą pomiarowej tomografii komputerowej. Metodę rentgenowskiej tomografii komputerowej zastosowano do oceny niepewności pomiaru elementów wykonanych z ABS techniką osadzania topionego materiału (FDM) z zastosowaniem drukarki UP! 3D. Dokonano badania i oceny na podstawie modelu projektowanego ze wspomaganiem komputerowym (CAD) z uwzględnieniem zarówno powierzchni zewnętrznych, jak i wewnętrznej struktury oraz połączeń pomiędzy poszczególnymi elementami.

Opis:
Fossil remains of reindeer (Rangifer tarandus) occurring outside their present range are an important indicator of formerly cold climatic conditions, but are easily confused with those of the red deer (Cervus elaphus). The locality of Kiputz IX has yielded one of the best-preserved Late Pleistocene reindeer populations of the southern Pyrenees, occurring in association with Bison priscus and the much more abundant Cervus elaphus. Fossil remains from this site are mostly complete and not affected by human intervention, thus creating the perfect conditions for reliable osteometric analyses. Here, we quantify diagnostic morphological features of the scapula and the humerus of Cervus elaphus and Rangifer tarandus to establish the potential of these bones to aid in interspecific discrimination. In the case of the scapula, the best species discriminator is the ratio of the minimum anteroposterior diameter of the scapular neck and the development of the articular process, while the breadth of the trochlea is the best discriminator in the case of the humerus.

Opis:
The article focuses on indicating a set of competencies required for production branches based on the data regarding the Podlaskie labour market. The data was collected using quantitative surveys (in the form of questionnaires). Then, the Authors used network analysis to visualise the collected data and indicate the most frequently indicated set of competencies. Based on the opinion of respondents, the most popular competencies were professional knowledge and technical skills. These two competencies were also the most popular combination. Communication, self-reliance, thoroughness/reliability, sharing knowledge and experience, and teamwork/ collaboration also proved to be important. The entire set of the competencies is strongly linked, with professional knowledge and technical skills forming the foundation. Knowledge of foreign languages has also been identified as significant as well as decision making, which was, however, less frequently connected with the above. Despite the dominance of the two competencies attributed to the professional group, this group of competencies was the least numerous. Based on the example of the Podlaskie Region, the study informs about the set of competencies sought by manufacturing companies. Also, the most important competencies typical for individual branches are noted. This collection of competencies can serve as a basis for further theoretical considerations in the field of competency identification aimed at the production industry. In some cases, competencies indicated for different industries coincide, while in others they are divergent. The set of competencies indicated by the respondents informs job seekers in the area of production as well as institutions such as Voivodship Labour Office in Bialystok, whose task, among others, is to appropriately orientate the development of future employees.

Road crashes remain an important public health issue. This study aimed to assess the perceived importance of four types of measures for reducing traffic crash rates. For this cross-sectional study, data were obtained from a national sample of 1,200 Spanish drivers responding to a telephone-assisted survey. The most valued types of road safety measures were those related to users’ training/education and infrastructural improvements. Further, individual perceptions were influenced by both demographic and trip-related factors. The results of this study support the idea that user features remain a relevant issue to consider when developing and implementing road safety measures.

Opis:
In semiarid regions, the main purpose of afforestation has been to provide a protective vegetative cover in order to prevent or reduce soil erosion. This paper shows the results of a study carried out in some areas afforested in the 1970s, in steep slopes and mostly in marls. Afforestation where performed using terraced with subsoiling, so the existing scrub vegetation was removed and Pinus halepensis was planted. The main conclusion is that human action developed in this semi-arid territory, perhaps because the technique applied was not the most suitable for afforestation, has led to the geomorphological activation of the slopes and the emergence and large development of gullies.

Opis:
The essential oil of a protected Spanish species, Thymus praecox ssp. penyalarensis, was firstly analyzed [Gas Chromatography-Mass Spectrometry (GC-MS)] from wild populations during the phenological stages of flowering and fruiting. In flowering, the yield was 1.2%, and the major components were identified as thymol (18.5%), p-cymene (14.6%), carvacrol (11.6%), and γ-terpinene (10.1%). In fruiting, the yield was 0.9% and the major components resulted to be p-cymene (19.0%), carvacrol (16.5%), and borneol (10.5%). An experimental cultivation of the taxa was made also in order to analyze its essential oil as well. The yield was 1.3%, and the main compounds were thymol (19.1%), p-cymene (17.0%), and γ-terpinene (12.3%). Finally, the composition of the essential oil of this plant is discussed in relation to chemotaxonomic and biogeographical aspects.

Opis:
There is a real need to use various efficient energy supply systems that are not aggressive towards the global environment. Hydrogen has been seen in different research papers presented in the literature as an essential fuel to generate energy in various energy storage systems. As it is well-known, it is possible to generate renewable electricity using electrolysis. The hydrogen produced can be sold as fuel for various systems, most notably its use in solid oxide fuel cells and a host of modern applications today. Current low-temperature fuel cells are ideal for hydrogen operation, but are not suitable for hydrogen mixtures. In this article, a mathematical analysis was carried out to generate electrical energy in a fuel cell, fed with synthesis gas from the residual biomass gasification process; the primary interest was the generation of electrical energy, solid oxide fuel cell (SOFC), which operate at the temperature of the gas at the outlet of the gasifier were analyzed. The practical efficiency obtained and the theoretical results of the SOFC operation were shown.

Murine melanoma B16F0 cells were transfected with SA:DPPC:DOPE (2:1:1 molar ratio) liposomes associated with a plasmid encoding murine IL-12. Stearylamine, a cationic lipid, showed a greater transfection efficiency compared to DOTAP-containing liposomes. The lipid:DNA ratio was 2:1 (w/w). Control groups were mock transfected or transfected with an empty plasmid (pNeo). pNeo or IL-12 transfected cells and controls were inoculated intradermically into the dorsal region of the foot or the lateral flank of C57BL6 mice. Results showed that IL-12 expression had a marked effect on in vivo growth of B16 melanoma tumors developed in both anatomic sites, significantly retarding their growth and prolonging host survival.
