Grout laminated wood decks (GLWDs), representing the third generation of stressed wood decks, comprise either laminates or logs trimmed to obtain two parallel faces. The logs or laminates, running along the span, are held together by means of transverse internal grout cylinders that may be in either compression or tension. Two full-scale models of GLWD were constructed at Dalhousie University, Halifax, one with grout cylinders in compression and the other with the cylinders in tension. Service load tests conducted in Halifax showed that the former deck had better load distribution characteristics. Two years after the tests in Halifax, the models were shipped to The University of Manitoba in Winnipeg, where they were tested to failure under a central patch load. Because of miscommunication with the supplier, the logs of the GLWD with grout cylinders in compression were also trimmed to the third face that was kept at the bottom of the deck. The failure tests showed that despite its superior load distribution characteristics, the deck with grout cylinders in compression failed at a significantly lower load than the GLWD with cylinders in tension. It is argued that a planar surface in the logs at the flexural tension face not only reduces their flexural stiffness but also brings the defects of wood to the surface with maximum stress. The deck with the flat bottom surface underwent tension failure of the most heavily loaded logs, whereas the deck with the intact round surface of the logs at both top and bottom failed by horizontal splitting of all the logs.Key words: articulated plate, bridge deck, grout laminated deck, orthotropic plate, timber.

During the analysis of morbidity by nosological forms of diseases of the class «Diseases of the skin and subcutaneous» cellulose in cadets of two higher military educational institutions for 2012–2017, studying in the Kaliningrad enclave, the features were revealed. Diseases included in only three blocks were registered: infections of the skin and subcutaneous tissue; dermatitis and eczema; other diseases of the skin and subcutaneous tissue. The share of the first block reached 80.4–73.4 %; the second — 18.2 – 20 %, the third 1.4 – 5.8 %. The level and duration of the period of prevalence of the first block of diseases over the second was 4 among cadets at the university № 1, in the university № 2–3 years. The leading diseases were pyoderma (at university No. 1 – 120.9 ± 5.6‰, No. 2 – 42.5 ± 4.3‰), skin abscess, furuncle and carbuncle (No. 1 – 40.2 ± 3.4‰, No. 2 – 15.2 ± 2.6‰). The incidence of pyoderma in each university prevailed among cadets of the first three years of study over abscess, boil and carbuncle. Pyoderma in the university № 1 in each year of study was recorded reliably less often from 1 to 4 courses. Abscess, furuncle and carbuncle were registered significantly more often in the first course than in the second, in the second or fourth courses — the same, and only in the fifth course significantly less often than in previous courses. Pyoderma among cadets of 1 – 2 years of study at the university № 2 was registered in the same way, in the third-fifth courses — 2.8 – 4.4 times less often. Abscess, furuncle and carbuncle were registered by years of study without significant differences. Differences in the incidence of skin and subcutaneous tissue infections among cadets of the two universities indicated the presence of specific health risk factors. This necessitates further retrospective studies and full-scale (microbiological, immunological, etc.) tests.

AbstractThe article describes methodology of research on transparent wood in architectural constructions which is to be held at Faculty of Civil Engineering at Technical University in Košice. The goal is to set multiple stages of research to be able to obtain samples of transparent wood of different species and to evaluate them and subsequently to design constructions suitable for the properties of the obtained material. The aim is to be for the constructions of façade systems and beams of composite cross-section, possibly with the focus on “I” section beams made of transparent wood, but different approaches will also be considered. First, the designs will be evaluated and adjusted using suitable software and after, they will be built and experimentally tested. As the technology at the university will not allow the production of full scale models, some models in scale shall be produced and evaluated in Košice during the upcoming months.

Abstract: The aim of doctoral programs in psychology is to help students become competent psychologists, capable of conducting research and of finding suitable employment. Starting with a brief description of the basic organization of the French university system, this paper presents an overview of how the psychology doctoral training is organized in France. Since October 2000, the requisites and the training of PhD students are the same in all French universities, but what now differs is the openness to other disciplines according to the size and location of the university. Three main groups of doctoral programs are distinguished in this paper. The first group refers to small universities in which the Doctoral Schools are constructed around multidisciplinary seminars that combine various themes, sometimes rather distant from psychology. The second group covers larger universities, with a PhD program that includes psychology as well as other social sciences. The third group contains a few major universities that have doctoral programs that are clearly centered on psychology (clinical, social, and/or cognitive psychology). These descriptions are followed by comments on how PhD programs are presently structured and organized. In the third section, I suggest some concrete ways of improving this doctoral training in order to give French psychologists a more European dimension.

The aim of the research project solved at the University of Finance and administration is to construct a new bankruptcy model. The intention is to use data of the firms that have to cease their activities due to bankruptcy. The most common method for bankruptcy model construction is multivariate discriminant analyses (MDA). It allows to derive the indicators most sensitive to the future companies’ failure as a parts of the bankruptcy model. One of the assumptions for using the MDA method and reassuring the reliable results is the normal distribution and independence of the input data. The results of verification of this assumption as the third stage of the project are presented in this article. We have revealed that this assumption is met only in a few selected indicators. Better results were achieved in the indicators in the set of prosperous companies and one year prior the failure. The selected indicators intended for the bankruptcy model construction thus cannot be considered as suitable for using the MDA method.

"A Short Modern History of Studying Sacrobosco’s De sphaera. The treatise generally known as De sphaera offered at the beginning of the 13th century a general image of the structure of the cosmos. In this paper I’m first trying to present a triple stake with which this treaty of Johannes de Sacrobosco (c. 1195 - c. 1256). This effort is intended to draw a context upon the treaty on which I will present in the second part of this paper namely, a short modern history of studying this treaty starting from the beginning of the 20th century up to this day. The first stake consists in the well-known episode of translation of the XI-XII centuries in the Latin milieu of the Greek and Arabic treaties. The treatise De sphaera taking over, assimilating and comparing some of the new translations of the texts dedicated to astronomy. The second Consists in the fact that Sacrobosco`s work can be considered a response to a need of renewal of the curriculum dedicated to astronomy at the University of Paris. And the third consists in the novelty and the need to use the De sphaera treatise in the Parisian University’s curriculum of the 13th century. Keywords: astronomy, translation, university, 13th Century, Sacrobosco, Paris, curriculum"

University is relatively considered a stressful moment in the life of students due to numerous academic workloads and academic activities. The situation is further aggravated by the fact that some university students are in emerging adulthood, a developmental period which is psychologically fraught with uncertainty, instability and identity issues among others. Added to these, the context of most universities like Cameroon which is marred with political, economic and social turbulence common to other developing societies in the sub Saharan region makes life unbearable. Looking at the challenges that confront tertiary education students in the third decade of life, increases possibilities of fears that they will founder thus narrowing the route to a blossomed transition into adulthood and through the university from home into the world of work. However, observations reveal that some have remained hopeful as they continuously believe in themselves and their worth. As such, they have resiliently shrugged off the vast burden placed on them by the adult society as they struggle intentionally with continuous efforts to succeed. Being hopeful and self-efficacy beliefs are observed to be some of the effective drivers that pull emerging adults through the storms of university transition thus facilitating positive development into subsequent life stages. Unfortunately just a paucity of literature albeit theoretically actually narrates via scholarly corridors the monumental successes recorded by students as they sail flourishingly through university in the midst of storms an in the third decade of life. This paper examines and addresses the foregoing through the lenses of some theories.
