Authors: LEWICKA Aleksandra , WIDOMSKI Marcin K. , ŁAGÓD Grzegorz 
Published: September 2018

Abstract
The paper presents application of multivariate economic analysis to decision making process of selection of the most economically suitable concept of sanitary sewage system for a selected rural settlement in Poland. Analysis covered Drelow, Lublin Voivodeship, settlement area with 121 households with 421 residents and several municipal services. Three variants of sewage removal and treatment were developed: unconventional gravity-pressure network, gravity-pressure network combined with local domestic wastewater treatment plants (WWTPs) and full pressure sewerage network. In all variants, the container wastewater treatment plant of daily capacity 450 m3 day-1 was applied. Estimations of investment and exploitation costs for 30 years period operation were performed. Economic multivariate analysis was based on: Payback Period, Dynamic Generation Cost (DGC), Net Present Value (NPV) and Benefit-Cost Ratio (BCR). The obtained indicators were the input data for the weighted sum model allowing to select the most appropriate variant. Analysis showed that the most suitable was variant No 1. However, it was also noticed that all of the tested designs were ineffective economically.
Triaxial Tests On Weak Cohesive Soils – Some Practical Remarks (Part 1)
Authors: KOWALSKA Magdalena , JASTRZĘBSKA Małgorzata 
Published: September 2018

Abstract
Standard procedures of triaxial testing recommended e.g. in Eurocode 7 are often unsatisfactory in case of weak cohesive soils (soft and very soft clays, clayey soils with organic content, etc.), mainly due to the high deformability of these soils. Forming a specimen from material sampled in situ and installation of the necessary equipment (a membrane, filter paper strips or on-sample sensors, etc.) may be very difficult and can influence the quality of the test results. This paper (part 1/2) presents detailed description and discussion of the issues related to weak soil sampling and forming of triaxial specimens, based on the Authors’ own experience and literature review. Some solutions, which make the work with weak soils easier and, at the same time, increase the reliability of the results, are suggested e.g.: an “extra consolidation” in a sampler or alternative preparation of the specimen from slurry. Due to the ampleness of the problems related to testing of weak cohesive soils, another issues, such as installation of a triaxial specimen in a chamber or equipping it with different accessories, have been described in part 2 of this paper. In the Authors opinion, the text (parts 1 and 2) may constitute an important hint for researchers completing a triaxial testing system designated for testing weak cohesive soils.

Authors: CZOP Monika , KAJDA-SZCZEŚNIAK Małgorzata 
Published: September 2018

Abstract
Economic development of a country as well as growing consumption causes a rise in the amount of wastes, mainly municipal wastes. Basic sources of the municipal wastes are households and public buildings. When Poland joined European Union, it was necessary to introduce many changes related to the waste management. Gradually implemented actions aim at limiting the amounts of municipal wastes deposited in landfills and reducing biodegradable fraction of wastes. Production of fuel from the municipal waste fraction constitutes an important element of modern waste management system. Moreover, it becomes an alternative to exhaustible resources of fossil fuels and a valuable source of energy to be used in industry, e.g. in cement industry.
The article presents characteristics of a selected production plant of alternative fuel, which operates in the area of Silesian Voivodship. The purpose of the test was to analyse the quality of the readymade alternative fuel and ballast fraction formed in the device. Achieved test results were applied to the valid legal regulations in the context of the best possible waste management.
The Concept Of Multifuncional Wall – An Energy System Integrated In A Single Wall
Authors: Figaszewski Jarosław , SokoŁOwska-Moskwiak Joanna 
Published: September 2018

Abstract
In 1981 Mike Davis proposed a new design of the glass wall, which he called a polyvalent wall that would dynamically respond to changing environmental conditions. The idea of an inter-active component in a building envelope has become a source of inspiration for the proponents of external wall concepts. The proposed designs are important because they apply principles of multifunctionality based on cooperation between the wall layers and the dynamic reaction of changing external and internal thermal conditions. The multilayer wall, therefore, plays a major role in the thermal shielding of a building and is a key component in energy efficiency. And the use of new construction materials the wall functionality has been expanded. This application has also expanded the role of a wall in the process of energy management of a building. A non-transparent wall can produce electricity, supply heat from solar radiation, absorb, store and distribute heat. It can be responsible for stabilizing room temperatures. The cooperation between individual layers also has an impact on energy efficiency and on the microclimate of a given building. This paper will present different ways of energy activation in external walls with a special focus on the photovoltaic panels/modules (PV), the transparent insulation (TIM) and phase change materials (PCM). New materials can be included in the partition structure in different configurations such as a single or a bi-material component for improving thermal effects.

Flow Capacity Analysis For Mpl Katowice Pyrzowice Terminals With The Indication Of Zones Requiring Architectonic Changes
Authors: Sitek Michał 
Published: September 2018

Abstract
In order to improve the quality of passenger service at an airport terminal it is necessary to continuously monitor the level of the services rendered. Devising a strategy for the process of modernization or extension of an airport, with a view to maintaining or elevating the standards offered, requires a skilled determination of the investment commencement time. The rationale behind such investments is a deliberate prognosis of changes in the numbers of passengers visiting the airport in order to avoid exceeding maximum capacity at peak times. The launch of construction works while maintaining continuity of operations at the airport is connected with a conscious utilization of any available spatial reserves within the existing structures. Analyses of flows of users receiving services in various zones of a building, in consideration of the limit values set for the appropriate standards, are some of the tools that facilitate their proper design. Design that includes the statistical trends of changes in the amount of users receiving service requires a responsible and conscious decision making around the shaping of relations between spatial arrangements and auxiliary technologies. The paper presents different methods of working with large quantities of information which the designer must analyze and comprehend. The aim is to make sound investment and design decisions that would precede and prevent the loss of efficiency and performance in relation to the satisfaction of users.
Fem Analysis Of Corrugated Web Girders Reinforced With Tensioned Diagonal Braces
Authors: BasiŃski Witold , Kowal Zbigniew 
Published: September 2018

Abstract
The study presents the application of FEM numerical analysis, performed with the Abaqus software [1], for theoretical estimation of the ultimate and critical shear and flexural resistance of corrugated web girders reinforced with tension diagonal braces. In FEM numerical models, different web failure modes, observed in physical experimental research into SIN girders were taken into consideration [2]. That was done depending on the inclination angle β of tension diagonal braces and the web thickness. FEM analysis of the shear resistance of corrugated web girders was performed using numerical models of girders. The webs, made from corrugated sheet, had the heights of 500, 1000 and 1500 mm, and the thicknesses of 2; 2.5 and 3 mm. Global shear and flexural load-displacement paths (LDPs) were determined for girder numerical models. In shear LDPs, the shares of cooperation between the corrugated web and tension diagonal braces were separated. For each numerical model, the estimates of the share of the corrugated web and diagonal braces in the shear resistance of SIN girders were produced. The results of the FEM numerical analysis of the resistance of corrugated web girders reinforced with tension diagonal braces were compared to the results of physical experimental research [2] into the girders of concern, and also with the results of calculations made for unreinforced girders acc. EC3 [19]. Conclusions were drawn and recommendations were produced, which can be applied to the construction and dimensioning of corrugated web girders reinforced with tension diagonal braces. The Abaqus software was adjusted to solve the problems related to the phenomena revealed by the research [2].

Authors: KRÓL Małgorzata , KRÓL Aleksander 
Published: September 2018

Abstract
The natural smoke removal is a common way of protection of the escape routes in Poland. The operation of such systems is based on the phenomenon of buoyancy. The intensity of this effect depends on the temperature difference between smoke and ambient air. The second factor influencing the natural smoke flow inside a building is wind. The wind influence is significantly important for buildings equipped with smoke removal windows. However, also the other natural smoke removal systems could be affected by the wind impact under adverse ambient conditions.
There are the features of the wind described in the first section of the paper. Next, the impact of the wind on a building is shown. Two wind speeds and two wind directions were considered. A building model in the extended computational domain was built. The model was solved with the use of Ansys Fluent. The distributions of dynamic pressure caused by the wind on different facades of the building were presented. The particular attention was paid to the dependence of pressure distribution on the wind direction.

REVIVE TO SURVIVE AND DEVELOP. CITY CENTRES OF SHEFFIELD (U.K.) AND KATOWICE (PL)
Authors: WŁODARCZYK Anna Marta , WŁODARCZYK Michał 
Published: September 2018

Abstract
In the beginnings of 21 century revitalization by means of public open space planning is becoming more and more popular. The purpose of the paper is to juxtapose (not to compare) two European examples of public open spaces created in areas, which are neglected in urban and landscape way: The revitalized centre of the Sheffield post-industrial steel-city in England and the former coal mine area of the present new Silesian Museum in Katowice, Poland.
The empirical and analytical methods were applied, like in situ analysis in Sheffield: scientific walk, photo-documentation, interviews with experts, and research of professional material from the City Council (2014, 2016–2017). In Katowice: the field work, professional architectural supervision of the investment process, as well as the cooperation with architects and city planners (also by the Master Plan 2010) had been carried out during eight years (2006–2014).
The results show various approaches to public open space planning in post-industrial city-centres. In Sheffield the main attention is paid to the interconnected and safe pedestrian areas. In contrary in Katowice the planning efforts focus on architectural design, while the easy accessible and networked common spaces are missing. These differences are rooted in the urban and landscape strategies, assigned in the master plan (in one case), and the lack of such strategies (in the other case).

Published: September 2018

Abstract
Technological advances in manufacturing smart high-performances electronic devices, increasingly available at lower costs, nowadays allow one to improve users’ quality of life in many application fields. In this work, the human–machine interaction obtained by using a next generation device (Myo armband) is analyzed and discussed, with a particular focus to healthcare applications such as upper-limb prostheses. An overview on application fields of the Myo armband and on the latest research works related to its use in prosthetic applications is presented; subsequently, the technical features and functionalities of this device are examined. Myo armband is a wearable device provided with eight electromyographic electrodes, a 9-axes inertial measurement unit and a transmission module. It sends the data related to the detected signals, via Bluetooth Low Energy technology, to other electronic devices which process them and act accordingly, depending on how they are programmed (in order to drive actuators or perform other specific functions). Applied to the prosthetic field, Myo armband allows one to overcome many issues related to the existing prostheses, representing a complete electronic platform that detects in real-time the main signals related to forearm activity (muscles activation and forearm movements in the three-dimensional space) and sends these data to the connected devices. Nowadays, several typologies of prostheses are available on the market; they can be mainly distinguished into low-cost prostheses, which are light and compact but allow for a limited number of movements, and high-end prostheses, which are much more complex and featured by high dexterity, but also heavy, bulky, difficult to control and very expensive. Finally, the Myo armband is an optimum candidate for prosthetic application (and many others) and offers an excellent low-cost solution for obtaining a reliable, easy to use system.

Evaluation of Modified Hodge Test as a Non-molecular Assay for Accurate Detection of KPC-producing Klebsiella pneumoniae
Authors: GHASEMNEJAD ATOSSA , DOUDI MONIR , AMIRMOZAFARI NOUR 
Published: September 2018

Abstract

Klebsiella pneumoniae carbapenemase (KPC) have become a major therapeutic challenge because of its increasingly fast dissemination throughout the world. Accurate detection of KPC is essential for optimal treatment. The Clinical and Laboratory Standards Institutes (CLSI) for fast detection of KPC producers currently recommend Modified Hodge Test (MHT) and Carba NP test. MHT can directly detect carbapenemase production in Enterobacteriaceae isolates. The current study was conducted to evaluate the capacity of MHT with two carbapenem disks for accurate detection of KPC. MHT was performed according to guidelines of CLSI to identify isolates with carbapenem resistance. In doing so, two substrates of MHT were assigned into two groups for examination: meropenem and ertapenem groups. A total of 96 non-repetitive clinical isolates of Klebsiella pneumoniae were tested. The presence of the bla
KPC gene in each MHT-positive isolate was examined by PCR. A total of 54 isolates exhibited reduced susceptibility or resistance to carbapenems. Sensitivity of MHT with two carbapenem disks was similar. Specificity of the MHT with meropenem disk was 64% and with ertapenem disk was 53%. Detection of KPC by MHT with meropenem disk was found to be more effective than with ertapenem disk. Based on our results, the presence of KPC does not in itself influence the categorization of resistance. Therefore, the use of MHT with ertapenem disk for the rapid detection of KPC among K. pneumoniae for infection control should not be recommended.

Published: September 2018

Abstract
Human nerve growth factor β (β-NGF) is considered a major therapeutic agent for treatment of neurodegenerative diseases. We have previously reported the optimized conditions for β-NGF overproduction in Escherichia coli in a shake-flask culture. In this study the optimal %DO (dissolved oxygen) and post induction temperature values for improved production of β-NGF were found in the bioreactor scale using response surface methodology (RSM) as the most common statistical method. Also, for further enhancement of the yield, different post-induction periods of time were selected for testing. In all experiments, the productivity level and bacterial cell growth were evaluated by western blotting technique and monitoring of absorbance at 600 nm, respectively. Our results indicated that %DO, the post-induction time and temperature have significant effects on the production of β-NGF. After 2 hours of induction, the low post induction temperature of 32°C and 20% DO were used to increase the production of β-NGF in a 5-l bioreactor. Another important result obtained in this study was that the improved β-NGF production was not achieved at highest dry cell weigh or highest cell growth. These results are definitely of importance for industrial β-NGF production.

Background:Research suggests that men who have sex with men (MSM) often engage in high-risk sex and use illicit substances.Objective:To increase understanding of HIV knowledge and vulnerability among adolescent and young adult MSM, with a focus on alcohol and drug use and transactional sex.Methods:We conducted in-depth interviews and Focus Group Discussions (FGDs) with adolescent (aged 15-17 years) and young adult (aged 18-29 years) MSM in Kumasi, Ghana. MSM who reported recent alcohol and/or substance use or engagement in transactional sex were eligible. Questions covered HIV-related knowledge, experiences with substance-use and transactional sex, and attitudes regarding sexual risk-taking and HIV-related services. Data were analyzed thematically using NVivo 10.0 software.Results:Ninety-nine MSM participated in 44 interviews and 8 FGDs. Most were attending or had completed secondary school. HIV knowledge was high, but with major gaps. Most consumed alcohol; one-fourth used drugs. Alcohol and substances were consumed to enhance pleasure during sex with another man. Transactional sex was common and positively viewed. Half of the participants used condoms inconsistently or never, and self-perceived HIV risk was high. Nearly half faced stigma-related barriers to accessing HIV-related services.Conclusion:As Ghana strives to achieve the UNAIDS’s 90-90-90 global targets (90% of people living with HIV know their status, 90% who know their status are on sustained treatment, and 90% of those on treatment are virally suppressed), we recommend enhancing MSM-targeted prevention programs, improving care options, and increasing use of critical clinical HIV-services by ensuring that MSM receive unbiased, confidential care.
