Published: October 2017

Cel pracyCelem pracy była ocena częstości występowania oraz nasilenia subiektywnego upośledzenia funkcjonowania w ciągu dnia wśród osób deklarujących objawy bezsenności w zależności od wieku, płci oraz typu i czasu trwania snem tych objawów.MetodaGrupa badana składała się z osób biorących udział w badaniu NATPOL. Spośród 2413 badanych (1245 kobiet i 1168 mężczyzn) w wieku 18 – 79 lat wyodrębniono grupę osób deklarujących objawy bezsenności liczącą 1221 osób (736 kobiet i 485 mężczyzn) w wieku 18-79 lat. Dane dotyczące rodzaju objawów bezsenności, czasu ich trwania oraz subiektywnej oceny funkcjonowania poddano analizie statystycznej.WynikiUpośledzenie funkcjonowania zgłaszało 825 osób, czyli 67,7% deklarujących subiektywną bezsenność i było ono częste wśród kobiet. Wśród osób doświadczających objawów bezsenności powyżej 2 tygodnie upośledzenie funkcjonowania dotyczyło 72,4% osób, wśród osób z objawami trwającymi do 2 tygodni 70,7% i z objawami trwającymi kilka dni 64,9%. Wśród osób ze znacznym stopniem upośledzenia funkcjonowania 20% stanowiły osoby o najdłużej utrzymujących się objawach bezsenności. Dla krótszych okresów wartości te wynosiły odpowiednio 8,6% i 6,9%. Wśród z niewielkim upośledzeniem funkcjonowania dominowały osoby z najkrótszymi okresami utrzymywania się objawów bezsenności – odpowiednio 32,5% i 35,3%. W grupie wiekowej 18-24 lata najczęstsze było łagodne upośledzenie funkcjonowania (66,66%).WnioskiSubiektywne pogorszenie funkcjonowania w ciągu dnia jest powszechnym problemem wśród osób deklarujących bezsenność. Występuje częściej u kobiet a częstość jego występowania i nasilenie są większe u osób z dłuższym okresem utrzymywania się objawów bezsenności. Rozpowszechnienie pogorszenia funkcjonowania nie zależy od wieku, a jego natężenie jest najmniejsze u osób w wieku 18-24 lata.

Abstract
Mangan, S, Ryan, M, Shovlin, A, McGahan, J, Malone, S, O'Neill, C, Burns, C, and Collins, K. Seasonal changes in Gaelic football match-play running performance. J Strength Cond Res 33(6): 1686–1692, 2019—Time of season influences performance in many team sports; however, the anomaly has not yet been examined with regards to elite Gaelic football. Global positioning systems (4 Hz; VX Sport, Lower Hutt, New Zealand) were used to monitor 5 elite Gaelic football teams over a period of 5 years (2012–2016). In total, 95 matches equated to 780 full player data sets. Running performance was characterized by total distance (m) and high-speed distance (≥17 km·h−1; m). High-speed distance was further categorized into 4 match quarters. Time of season was determined by month of the year. Time of season had a significant effect on total distance (p ≤ 0.001 partial η2 = 0.148) and high-speed distance (p ≤ 0.001 partial η2 = 0.105). August and September were significantly different from every other month for total distance (p ≤ 0.001) and high-speed distance (p ≤ 0.002). Month of season and match quarter had a significant interaction with high-speed distance (p ≤ 0.001 partial η2 = 0.106). High-speed distances run in the fourth quarter in August (478 ± 237 m) and in September (500 ± 219 m) were higher than any other quarter in any other month. This is the first study to show that time of season influences running performance in Gaelic football. The findings have major implications for training practices in Gaelic football.

Mosier, EM, Fry, AC, and Lane, MT. Kinetic contributions of the upper limbs during countermovement. J Strength Cond Res 33(8): 2066–2073, 2019—This study examined the kinetic contributions of the upper extremities during countermovement vertical jumps (CMVJs) while using arm swing (AS) or no arm swing (NAS) conditions. Fourteen healthy men (

± SD; age = 24.1 ± 3.9 years) volunteered for this investigation. Subjects performed in random order a total of 6 jumps consisting of 3 AS and 3 NAS CMVJs. A motion capture system was used to analyze the kinetic data. Paired samples t-tests were used to examine the subjects' mean differences in the AS and NAS CMVJ trials (p<0.05). Results for all subjects were determined for each jump subjects were determined for each jump performed, with statistical analyses performed on mean values for all 3 jumps per subject. The AS significantly increased the vertical jump height (VJH) by an average of 0.07 ± 0.03 m (3.0 ± 1.3 inches). Dual-energy X-ray absorptiometry scans determined that the upper limbs were 12.0% of the total body mass. Movement of the upper limbs during the AS CMVJ produced 32.2 ± 7.0% of the total mean ground reaction force (GRF), and 11.3 ± 2.2% during the NAS CMVJ. The enhancement of performance when jumping using an AS resulted in a 13.6% increase in VJH. The contribution of the upper limbs during the AS CMVJ averaged 31.5% of the peak GRF, which occurred immediately before takeoff. The upper extremities can greatly influence vertical jump performances and the accompanying kinetics. When analyzing jump GRFs, one must be aware of how much the upper limbs contribute to these forces. In addition, proper AS mechanics must be emphasized when instructing correct jump technique.
Locating Wood Defects Based on Vibration Modes
Authors: Miao Y. , Zhong M. , Liu Z. 
Published: October 2017

Abstract
The first six lowest-order resonance frequencies, and their corresponding vibration mode displacements along the length of Larch boards, were obtained by modal analysis. Plots of the first six bending modes of these Larch specimens were obtained using measurement data. Results showed that, compared with specimens showing small area defects, specimens with larger areal defects exhibited smaller resonance frequencies. The influence of defects on the first- and second-order modes was not obvious, but the defects produced obvious deviations in the next four lowest-order modes. In regard to mode shape, sudden deviations were evident near defects. Whether a large area defect existed in a specimen can be determined using the third-order mode, and the location of wood defects is detectable using the fourth-, fifth-, and sixth-order modes.

Published: October 2017

Abstract
Manufacturing testbeds are used to develop, test, and analyze technologies that address some of the current challenges facing the manufacturing sector. This paper provided a classification of manufacturing testbeds and categorized several existing testbeds based on each category specification. In addition, this paper introduced the System-level Manufacturing and Automation Research Testbed (SMART), a multidisciplinary testbed used for manufacturing research and education at the University of Michigan. SMART consists of a physical serial-parallel line equipped with sensors to collect data at both the machine and system level. Various tools were used to aggregate, analyze, and display this data in a cloud infrastructure. The system setup allowed for the discovery, testing, implementation, and analysis of new technologies. In addition, different simulations of SMART were developed to augment and study the testbed at the machine and system levels. A number of ongoing projects utilize SMART's physical and virtual capabilities. These projects cover a wide variety of areas, including centralized and decentralized control of manufacturing systems and performance monitoring and analysis.

Sleep spindles promote the consolidation of motor skill memory in young adults. Older adults, however, exhibit impoverished sleep-dependent motor memory consolidation. The underlying pathophysiological mechanism(s) explaining why motor memory consolidation in older adults fails to benefit from sleep remains unclear. Here, we demonstrate that male and female older adults show impoverished overnight motor skill memory consolidation relative to young adults, with the extent of impairment being associated with the degree of reduced frontal fast sleep spindle density. The magnitude of the loss of frontal fast sleep spindles in older adults was predicted by the degree of reduced white matter integrity throughout multiple white matter tracts known to connect subcortical and cortical brain regions. We further demonstrate that the structural integrity of selective white matter fiber tracts, specifically within right posterior corona radiata, right tapetum, and bilateral corpus callosum, statistically moderates whether sleep spindles promoted overnight consolidation of motor skill memory. Therefore, white matter integrity within tracts known to connect cortical sensorimotor control regions dictates the functional influence of sleep spindles on motor skill memory consolidation in the elderly. The deterioration of white matter fiber tracts associated with human brain aging thus appears to be one pathophysiological mechanism influencing subcortical–cortical propagation of sleep spindles and their related memory benefits.SIGNIFICANCE STATEMENTNumerous studies have shown that sleep spindle expression is reduced and sleep-dependent motor memory is impaired in older adults. However, the mechanisms underlying these alterations have remained unknown. The present study reveals that age-related degeneration of white matter within select fiber tracts is associated with reduced sleep spindles in older adults. We further demonstrate that, within these same fiber tracts, the degree of degeneration determines whether sleep spindles can promote motor memory consolidation. Therefore, white matter integrity in the human brain, more than age per se, determines the magnitude of decline in sleep spindles in later life and, with it, the success (or lack thereof) of sleep-dependent motor memory consolidation in older adults.

Published: October 2017

Waste of electrical and electronic equipment (e-waste) is the outcome of the technological progress in electronic industry determining the exponential growth in amount and variety of the electrical and electronic products (EEE), the growth of economical welfare and unsustainable consumption. E-waste management systems (MS), implemented in the EU countries are not able to cope with the e-waste problem properly, especially in the new EU member countries. The best case scenarios of e-waste MSs from advanced countries could not be transposed directly to the countries behind the requirements of efficiency. The analysis of particular e-waste MS is essential for evaluation of its complexity and peculiarity. The aim of this paper is to represent the research of agent based material flow analysis (MFA) in the e-waste MS, as the measure to reveal the potential points for improvement. MFA was performed as a flow of goods (EEE).
The case study of MFA employment for the Lithuanian e-waste MS represents the following benefit: 1) estimation of the real EEE flows, including amounts of e-waste generated; 2)detection of the roots of inefficiency; 3) starting point to perform structural selection of relevant impact factors determining the current operation of the system. The study demonstrates that agent based EEE flow analysis incorporating life cycle thinking approach for the national e-waste MS gives a broader view to the system than the administrative system used to cover. Therefore employment of EEE flow analysis is useful for improvement of the e-waste MS.

Printing industry is characterized by large variety of output production and applied technologies of its manufacturing. It leads to considerable fluctuations of technological parameters of editions, such as formats, volumes, number of printed copies and circulations. In these conditions it is necessary for the manager to respond on changes operatively, professionally and correctly. It demands from him/her knowledge of technologies, technique and specificity of printing industry.
Designs of regulatory-methodical materials for waste management in the printing industry, answering to a current state of technique and technology in this area, are necessary conditions of efficient activity of the enterprises. Unfortunately, the scientific forces which have remained in branch are estimated as very small and they experience difficulties in financing of scientific research designs. It is necessary to unite efforts of the printing enterprises for maintenance of is standard-methodical base of branch at modern level, and also to provide preparation of qualified professionals in the area under consideration.
Proposals on perfection of specifications of formation and management of printing industry waste also will be considered in the paper.
Biogas Production from Waste Glycerol with Inhibition from Carboxylic Acids
Authors: Beschkov V. , Angelov I. , Petrova P. 
Published: October 2017

One of the ways for waste glycerol utilization is biogas production. This biogas could be used for partial energy supply of the main biodiesel plant. An important hinder for this application is the accumulation of carboxylic acids leading to strong inhibition of the methanogenesis and shift to production of gas with very low methane content. The present paper studies the possibility of biogas production from waste glycerol in a multistage anaerobic digester composed by consecutively situated cells separated by baffles. This cascade-type bioreactor enables the separation of zones with different pH and organic acid content and therefore to achieve flexible operation. The experiments show stable pH-profile along the bioreactor stages with minimum pH-values in the middle cells. Identification of the intermediate products resulting of the digestion was carried out. A strong correlation between the acid content and the pH-value in each reactor stage was observed.
Microbiological study shows that the microbial profile along the reactor varies with the progress of fermentation. The initial glycerol biodegradation is accomplished by aerobes and facultative anaerobes, whereas the methanogenesis starts after the first stage and it is represented consecutively along the stages by the genera Methanosarcina, Methanobacterium and Methanobrevibacter. Their concentrations are strongly sependent on the pH values. It was shown that overloading with glycerol leads to gradual decrease of methane in the produced biogas with an un-desired long period of further restoration of the normal reactor functioning.

Many Swedish landfills are currently applied with a final cover. To minimise costs and the use of natural resources, waste materials can be a suitable substitute in landfill covers. Depending on the wastes’ contents, their mobility and in which layer of the final cover they are used, they could potentially contribute to the emission potential of the landfill. In this study the impact on landfill leachate quality from the drainage water of a final cover is investigated.
Part of a landfill and its cover, below the upper drainage layer, was simulated in lab scale: The simulated liner was constructed from a mixture of fibre and ash residues from paper pulp production and the foundation and gas drainage layer was simulated by bottom ash from a municipal solid waste incinerator. The waste below the liner was simulated by residues fromsorting of construction and demolition waste. The leachate from the simulated damaged landfill cover had elevated concentrations of many substances including metals, ions and organic matter. However, the simulated landfilled waste could sorb several of these. Ag, Cd, Cu, Hg, N, P, Pb and Sb were sorbed to such an extent that the effect from the cover leachate was unnoticeable. The only pollutants that passed through the waste unattenuated were As, K, Na, TOC, V and Zn. In a real landfill the sorption would be even better since the waste mass will be much larger compared to the cover. Despite elevated concentrations of potentially complex forming substances there was no evidence that the cover leachate enhanced the leaching of any contaminants from the waste. Altogether the results show that the use of the studied waste materials in landfill covers can only be expected to have a small effect on the concentration of contaminants in the leachate from the landfill.

Published: October 2017

The solution of global and local environmental problems demands consolidation of efforts of specialists (experts) from various areas of a science and technology. Education and training of ecologically competent experts is an essential task of a modern society for provision and maintenance of a favorable, ecologically safe environment for present and future generations of people on our planet. This purpose is served by widely known concept of the sustainable development which idea should be a basis in professional training specialists for various branches of a science, economy and education. The important means for exchange by experience, knowledge and designs between scientific and educational institutions,enterprises, companies, firms etc., are the international scientifically-practical conferences, seminars and forums. One of them is the International Youth Scientific Environmental Forum of the Baltic Region Countries «ECOBALTICA».
The history of carrying out of the Forum at the St.-Petersburg State Polytechnic University totals already almost 15 years. Some generations of young scientists and specialists who wereregularly taking part in the Forum in this period, had time to be formed and grow. An aim of the Forum «ECOBALTICA» is consolidation of international experience of solution ofapplied and fundamental issues of ecology and environmental protection, as well as the problems connected with reproduction of highly skilled engineering and scientific manpower at domestic and international level. Interest to the Forum was shown by participants not only from the countries of the Baltic region, but from many far states to Baltic Sea. It is important to notice that long-term cooperation with University of Kalmar city, Sweden, has allowed organizers of the Forum «ECOBALTICA » to raise its efficiency and to deduce it onabsolutely new organizational level.
As a result, there has been created in St.-Petersburg the system of measures directed to increase of efficiency of scientific and educational process in sphere of environmentalprotection, to develop bases of ecological culture of the people that has allowed to pass from discussion of scientific questions and education of qualified manpower, to direct influence on ecological conditions of the Baltic Region.
Approach for sustainable processes for the built environment in triple helix cooperation: the case of Storsjö strand in Östersund
Authors: Jonasson Jonas , Danielski Itai , Mikaelsson Lars Åke , Fröling Morgan 
Published: October 2017

The built environment is an important component for a sustainable society. Choices made today will affect society during decades to come, both regarding performance of buildings and in affecting what is possible choices regarding mobility, energy, waste handling and human well being in general. There have been several projects in Sweden and around the world aiming at better sustainability performance of new built areas. A strong experience from earlier projects is that it is not that easy to actually achieve high ambitions set up at project initiation; the most common example in this direction that requirements on energy efficiency are not achieved when measuring in actual use of the final building.
The project Storsjö Strand, a new township in Östersund in an earlier industrialized area, has aimed to work around identified earlier problems, using a strong interactivity and a triple helix process with the municipality, developers, and the university. The role of the university is to through an action research approach both be involved in the process to help guide it and to document and evaluate the process, with the research goal to contribute to and develop sustainable building processes for Sweden and elsewhere.
The Storsjö Strand project is presently an ongoing project. This paper describes the approach taken and how it is a development of earlier approaches for sustainable building processes and also evaluates early experiences of the triple helix process.
