TL;DR: In this article, the influence of the ArF laser irradiation on the surface energy of poly(ethylene terephthalate) was investigated, and the surface chemical changes, occurring upon the irradiation, were monitored by X-ray photoelectron spectroscopy and the changes in the surface geometrical structure were investigated by atomic force microscopy.
Abstract: The influence of the ArF laser irradiation on the surface energy of poly(ethylene terephthalate) was investigated. An effort was also made to elucidate the physical and chemical phenomena affecting surface energy (SE). The surface chemical changes, occurring upon the irradiation, were monitored by X-ray photoelectron spectroscopy (XPS) and the changes in the surface geometrical structure were investigated by atomic force microscopy (AFM). The contact angle values obtained with test liquids of different polarity (water and diiodomethane) were measured while the surface energy was calculated by the Owens–Wendt method. The nature of the physico-chemical changes occurring in the poly(ethylene terephthalate) surface layer upon ArF laser irradiation depended mostly on the energy per unit area of the laser pulse and the number of the laser pulses. The polar and dispersive components of the surface energy increased as a result of increasing the number of the laser pulses of energy which were below that of the PET...

TL;DR: Investigating the relationships among physical demands of two friendly matches and three task training sessions combining in a different way found the training routines did not replicate the main set of high intensity efforts experienced in competitive conditions.
Abstract: The aim of this study was to investigate the relationships among physical demands of two friendly matches (FMs) and three task training sessions (TS1,2,3) combining in a different way: a Small-Sided Game (SSG), Mini-Goals (MG), a ball Circuit Training (CT) and a Large-Sided Game (LSG): SSG+MG+LSG (TS1), SSG+CT+LSG (TS2) and MG+CT+LSG (TS3). The TS and match demands in running intensities were monitored in fourteen professional soccer players (age = 23.2 ± 2.7 years, height = 178 ± 6 cm, body mass = 73.2 ± 6.9 kg, mean and SD, respectively) using 10-Hz global positioning system devices, and players' perception of exertion was recorded after each session or match using a visual analogue scale. A one-way repeated measures ANOVA with a Bonferroni correction coupled with magnitude-based inferences were used. A principal component (PC) analysis was conducted on all variables to account for covariance. Three PCs were retained, explaining 76% of the variance: Component 1 explained 46.9% with the associated variables: Total Distance (TD) and distance covered in ranges of speed from >2.2 to 5 m/s and maximal running speed (MRS); and component 3 explained 9.5% and was represented by TD 5, TD, deceleration rate, acceleration rate, maximal running speed, exertion index, work rest ratio, and self-reported exertion. Therefore, the training routines did not replicate the main set of high intensity efforts experienced in competitive conditions. Additionally, PC analysis could be applied in order to select the most representative training and competitive conditions.

TL;DR: In this article, the electronic properties of the interface between n-type Si and metallophthalocyanines (MPcs) have been investigated, and the effect of density of interface states (Nss) and series resistance (Rs) on I-V, C-V and G-V characterizations of the Al/MPc/n-Si/Al Schottky barrier devices were investigated as a function of frequencies in the frequency range of 42 Hz-5 MHz at different temperatures in the range of 210-473 K.

TL;DR: Research on the mite (Acari) succession was carried out within six dęciduous forest stands of various ages dominated by lime trees and the abundance of the Astigmata presented a general increasing tendency and was positively corr—lated with the age of the forest stands.
Abstract: FALEŃCZYK-KOZ]ROG K., KACZMAREK S., MARQUARDT T., MARCYSIAK K. 20|2. Contribution to succession of mite (Acari) communities in the soil of Tilio-Carpinetum TRACZ' 1962 in nońhern Poland. Acta zool. cracoy.' 55(2): 47-57. Abstract. Research on the mite (Acari) succession was carried out within six dęciduous forest stands of various ages dominated by lime trees (Tilia cordata MILL ). The general mite density was correlated with the age of each stand (r:0.596). Four orders of mites węre recorded the Cryptostigmata were dominant and their abundance initially decreased and then increased following the ageing of the forest stands. A similar tendency was recorded for the Mesostigmata. The abundance of the Astigmata presented a general increasing tendency and was positively corręlated with the age of the forest stands. High correlations notęd betweęn the density of the Cryptostigmata' Mesostigmata and Prostigmata can indicate trophic and competitive relations between thosę mite communities. Among the families belonging to the Mesostigmata four succession tręnds of abundance and percentage share changes were found: creativę (Macrochelidae and Trematuridae), regróssive (Ascidae), rise and fall (Pachylaelapidae, Parasitidae, Veigaii'dae and Laelapidae) and ręstorativę (Rhodacaridae).

TL;DR: Evaluation model presented here is improved version of earlier attempts and applies the potential of fuzzy systems for linguistic modeling of rules and is a good tool for modeling the trends in information used to create the fuzzy rules of small fuzzy systems which together form a hierarchical fuzzy evaluation model.
Abstract: The paper presents the analysis and application of hierarchical fuzzy system to the problem of evaluation/measurement of the rehabilitation effects in post-stroke patients. Healthy people constitute reference group. Prevalence and impact of the stroke-related disorders on Health-Related Quality of Life (HRQoL) as a recognized and important outcome after stroke is huge. Quick, valid and reliable assessment of HRQoL in people after stroke constitutes a worldwide significant problem for scientists and clinicians - there are many tools, but no one fulfills all requirements or has prevailing advantages. Evaluation model presented here is improved version of earlier attempts and applies the potential of fuzzy systems for linguistic modeling of rules. It provides a great advantage as there are experienced clinicians working on the improvement of the rehabilitation methods but there is no intuitive formal model to measure their effects. The innovative element here is the use of Ordered Fuzzy Number model. It is a good tool for modeling the trends in information used to create the fuzzy rules of small fuzzy systems which together form a hierarchical fuzzy evaluation model.
