Opis:
Artykuł dotyczy problematyki kształcenia studentów wyższych uczelni pedagogicznych w kontekście rozwoju i modernizacji systemu szkolnictwa wyższego. Podstawowym czynnikiem wymuszających zmiany są procesy związane z globalizacją, takie jak zmiana stylu życia związana ze wzrostem tempa interakcji społecznej pod wpływem nowych technologii, migracją ludności, transferem usług oraz unifikacja kulturową wynikającą z kopiowania modelów konsumpcji i nieograniczonego rozprzestrzeniania idei. Wobec tych gwałtownie przebiegających zmian, jednym z najważniejszych zadań dla kształcenia pedagogicznego wydaje się stworzenie systemu profesjonalnej edukacji nauczyciela potrafiącego sprostać przyszłym wyzwaniom. W artykule przedstawiono priorytety i innowacje wprowadzane w tym zakresie na Ukrainie w odniesieniu do polskiego systemu edukacji i europejskich rozwiązań. Zwrócono uwagę na ich znaczenie w myśleniu o polityce edukacyjnej i formowaniu elementów strukturalnych systemu kształcenia oraz wpływ na rozwój wiedzy społeczeństwa.
The article deals with the problem of professional education of students of pedagogical universities. It is emphasized that an important task of pedagogical science is the development of a system for the modernization of university education. The basis and main stimulus of this process is globalization, a new world trend through which the way of life, the spread of consumer goods and ideas become standardized throughout the world. The main directions of the national priorities Ukrainian innovations and their importance for the Polish education system are presented. The areas of the Ukrainian-Polish cooperation of educational systems in the context of modern innovations and in the sphere of the European priorities are considered. Attention is drawn to the importance of thinking about educational policy and forming structural elements of the education system and the impact on the development of a knowledge society.

Nucleophilic amination, as a vital step in the synthesis of 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) using 1,3,5-trialkoxy-2,4,6-trinitrobenzene (TORTNB) and aqueous ammonia as the starting materials and catalyzed by phase transfer catalysis (PTCs) under mild conditions is described. Various phase transfer catalysts, such as crown ethers, tertiary amines, quaternary ammonium salts, poly ethers and cyclodextrin, and various experimental parameters, such as no. of equivalents of PTC, mole ratio of ammonium hydroxide to the starting material, reaction time, reaction temperature and cycle times of the organic phase were investigated. The crown ethers, especially 18-crown-6, show good catalytic activity and re-usability for the amination of 1,3,5-triethoxy-2,4,6-trinitrobenzene giving a yield of 96.52%. This makes for a safe process and suitable for scale-up, because the reactions are carried out under atmospheric conditions. The material synthesised by the new system was characterized by DSC, SEM and LPS.

Opis:
A novel magneto-optical current sensor (MOCS) with two sensing arms is proposed to improve the temperature stability. One of the arms, with a highly stable permanent magnet attached and orthogonal to the other one, is designed to provide a reference that follows the temperature characteristics of the sensing material. By a normalization operation between two arms, the temperature drift is compensated adaptively and a sensing output proportional to the measured current can be reached. A dual-input and dual-output structure is specially designed for the reference sensing arm to demodulate the DC Faraday rotation angle. This scheme compensates simultaneously two main temperature influence factors, the Verdet constant and linear birefringence. Validation tests were carried out and are discussed.

Opis:
Achilles tendon rupture is a severe injury with poor curative effect due to its anatomical characteristic and mechanical peculiarity. Internal fixation of limited loop (IFLL) with steel-wire has been applied on patients with tendon rupture to fix the broken ends before physical rehabilitation. The purpose of this study is to investigate the biomechanical property and radiological characteristic of such suture technique for the repairment of tendon rupture. Methods: Tendons of pigs’ hint feet were separated for the biomechanical study. Suture surgery was performed according to the protocol of IFLL. Biomechanical Testing Machine was adopted to conduct the biomechanical tensile load examination. The maximal load, elastic modulus and tendon stiffness of the stitched tendons with or without reinforcement were examined. Results: The maximum tensile load of the stitched tendons using IFLL reached 1/4 of the uninjured tendon’s maximum tensile load, indicating that such suture technique is capable of providing enough tension for the ruptured tendon. Surprisingly, tendons fixed with titanium wire showed the highest load tension, which was comparable to the undamaged tendon. Therefore, we found the biomechanical basis of using IFLL in effectively connecting the rupture ends of tendons. Conclusions: In conclusion, we provide biomechanical evidence for the use of IFLL in treatment of Achilles tendon rupture, by providing enough strength for the ankle function. Such suture technique could help the patients with better rehabilitation and reduced in-hospital stay after Achilles tendon injury.

Opis:
An effective warranty servicing strategy should be made considering both warranty cost and product availability. Based on the two-dimensional free repair warranty, a strategy combining the imperfect preventive maintenance and minimal repair is proposed where the imperfect preventive maintenances are implemented in a special subregion of the warranty and all other failures are repaired minimally. By modeling the warranty cost and product availability, we derive the optimum warranty servicing strategy and corresponding parameters to minimize the cost-effective of unit time. Finally, we provide a numerical illustration and a comparison with some other strategies.
Efektywna strategia obsługi gwarancyjnej powinna uwzględniać zarówno koszty gwarancji jak i dyspozycyjność produktu. W oparciu o pojęcie dwuwymiarowej gwarancji bezpłatnej naprawy, zaproponowano strategię łączącą niepełną konserwację zapobiegawczą z naprawą minimalną, gdzie działania obsługowe w ramach niepełnej konserwacji zapobiegawczej przeprowadza się w ramach specjalnego podobszaru gwarancji, a wszelkie inne uszkodzenia naprawia się w ramach naprawy minimalnej. Modelując koszty naprawy oraz dyspozycyjność produktu, wyprowadzono optymalną strategię obsługi gwarancyjnej oraz odpowiadające jej parametry w celu zminimalizowania kosztów na jednostkę czasu. Na koniec, proponowane rozwiązanie zilustrowano na przykładzie numerycznym oraz porównano z innymi strategiami

Opis:
Fibril formation of proteins and peptides is associated with a large group of major human diseases, including Alzheimer’s disease, prion disorders, amyotrophic lateral sclerosis, type 2 diabetes, etc. Therefore, understanding the key factors that govern this process is of paramount importance. The fibrillogenesis of polypeptide chains depends on their intrinsic properties as well as on the external conditions. In this mini-review we discuss the relationship between fibril formation kinetics and the sequence, aromaticity, hydrophobicity, charge and population of the so called fibril-prone conformation in a monomer state. The higher the population, the faster is the fibril elongation and this dependence may be described by a single exponential function. This observation opens up a new way to understand the fibrillogenesis of bio-molecules at the monomer level. We will also discuss the influence of the environment with focus on the recently observed dual effect of crowders on the aggregation rat es of polypeptide chains.

Opis:
As a non-steroidal anti-inflammatory drug, diclofenac, was commonly used as analgesic, antiarthritic and antirheumatic, and has frequently been detected in municipal wastewater treatment plants (MWTPs) effluents and demonstrated to be potentially environmental risk on human beings. In the present study, N, S co-doped TiO2 nano-crystallites decorated TiO2 nano-tube arrays (N, S-TiO2 NCs/TiO2 NTAs) photoelectrode was used to degrade diclofenac containing wastewater. In addition, the effects of some critical parameters including initial pH, external positive potential, sodium sulfate concentration and initial diclofenac concentration on the photoelectrocatalytic (PEC) degradation of diclofenac containing wastewater and dynamic characteristics were investigated systematically. Results showed that N, S-TiO2 NCs/TiO2 NTAs photoelectrode exhibited high PEC efficiency for the degradation of diclofenac, in which the PEC processes fitted well with the Langmuir–Hinshelwood (L–H) model. Furthermore, external additional anions such as Cl–, ClO– and NO3 – played an important role in inhibiting the degradation of diclofenac. Also, the N, S-TiO2 NCs/TiO2 NTAs photoelectrode possessed good stability for consecutive applications for degradation of diclofenac, which could potentially be utilized in wastewater treatment.

Opis:
The cambial activity and periodicity of secondary xylem and phloem formation have been less studied in tropical tree species than in temperate ones. Cambium activity is the only source of timber production. Studies on its activity and xylem formation can provide helpful data for dendrochronology and possible factors that control tree growth, the yield and quality of wood. Cinnamomum camphora is an important fast-growing tree for furniture and sculpture wood in South China. Its dynamics of cambial activity was not reported. During the growth season in 2011, five trees of Cinnamomum camphora plantation were monitored on the campus of Huazhong Agricultural University in central china (located on 113°41’ to 115°05’ E and 29°58’ to 31°22’ N). Sampling time was from 13, February 2011 to 13, February 2012. Some small stems of 15–20 cm length were selected to sample in the middle of 2–3 years old health branches in the central crown of these trees. The observational study found that the cambium of camphor trees was active from March to October and dormant from November to February. Onset of cambial cell division was observed in early March, one week after sprouting of new buds. The morphology of the cells and number of cell layers in the cambium zone varied throughout the year. In early March, cambium reactivated with the rising of temperature, the cell wall was relative thick. The number of cell layers increased from 2–3 in middle Feb. to 3–5. In June, the number of cell layers in cambium reached the maximum of 5–7 in a radial direction. In mid March, phloem cells began to differentiate, followed by xylem three weeks later. The number of cell layers in immature phloem and xylem increased dramatically before mid June and the increment of cell layers in xylem was almost fifth times of phloem in the differentiating process. The phloem cells mainly stopped dividing new cells in end of October, but xylem cells were still in the activity a week later. The annual activities of cambium was in accordance with the air mean temperature change in 2011–2012. The results showed that the cambial activity and formation of xylem and phloem were related to the environmental factors, especially the temperature.

Opis:
In order to completely eliminate, or greatly reduce the number of phase wraps in 2D wrapped phase map, Gdeisat and co-workers proposed an algorithm, which uses shifting the spectrum towards the origin. But the spectrum can be shifted only by an integer number, meaning that the phase wraps reduction is often not optimal. In addition, Gdeisat’s method will take much time to make the Fourier transform, inverse Fourier transform, select and shift the spectral components. In view of the above problems, we proposed an improved method for phase wraps elimination or reduction. First, the wrapped phase map is padded with zeros, the carrier frequency of the projected fringe is determined by high resolution, which can be used as the moving distance of the spectrum. And then realize frequency shift in spatial domain. So it not only can enable the spectrum to be shifted by a rational number when the carrier frequency is not an integer number, but also reduce the execution time. Finally, the experimental results demonstrated that the proposed method is feasible.

Opis:
This paper reviews two techniques that have been recently published for three-dimensional profilometry and proposes one shot profilometry using iterative two-step temporal phase-unwrapping by combining the composite fringe projection and the iterative two-step temporal phase unwrapping algorithm. In temporal phase unwrapping, many images with different frequency fringe pattern are needed to project, which would take much time. In order to solve this problem, Ochoa proposed a phase unwrapping algorithm based on phase partitions using a composite fringe. However, we found that the fringe order determined through the construction of phase partitions tended to be imprecise. Recently, we proposed an iterative two-step temporal phase unwrapping algorithm, which can achieve high sensitivity and high precision shape measurement. But it needs multiple frames of fringe images which would take much time. In order to take into account both the speed and accuracy of three-dimensional shape measurement, we get a new, and more accurate unwrapping method based on a composite fringe pattern by combining these two techniques. This method not only retains the speed advantage of Ochoa’s algorithm, but also greatly improves its measurement accuracy. Finally, the experimental evaluation is conducted to prove the validity of the proposed method.

Opis:
The thermal decomposition kinetics of 1-amino-1,2,3-triazolium nitrate (ATZ-NO3) was investigated by non-isothermal TG-DTG at various heating rates (2, 5, 10, 15, and 20 °C∙min-1). The results showed that the thermal decomposition of ATZ-NO3 consists of two mass-loss stages. The first mass-loss stage corresponds to the loss of nitrate anion and the substituent group, while the second stage corresponds to the splitting of the triazole ring. The kinetic triplets of the two stages were described by a three-step method. Firstly, the Kissinger and Ozawa methods were used to calculate the apparent activation energies (E) and pre-exponential factors (A) of the two decomposition stages. Secondly, two calculation methods (the Šatava-Šesták and Achar methods) were used to obtain several probable decomposition mechanism functions. Thirdly, three assessment methods (the Šatava, double-extrapolation, and the Popescu methods) were used to confirm the most probable decomposition mechanism functions. The reaction models for both stages are random-into-nuclear and random-growth mechanisms, with n = 3/2 for the first stage and n = 1/3, m = 3 for the second stage. The kinetic equations for the two decomposition stages of ATZ-NO3 may be expressed as [wzór]. Mathematical expressions for the kinetic compensation effect were derived.
