Authors: Gajda Stanisław , Gajda Jerzy 
Published: October 2017

Abstract
The intended aim of this article is to present approximation results of the exemplary measurements of EMERGENCY signal reception probability. The probability is under-stood as a distance function between the aircraft and a ground-based system under established conditions. The measurements were approximated using the properties of logistic functions. This probability, as a distance function, enables to determine the range of the EMERGENCY signal for a pre-set confidence level.

Flexible Structure Control Scheme of a UAVs Formation to Improve the Formation Stability During Maneuvers
Authors: Kownacki Cezary , Ambroziak Leszek 
Published: October 2017

Abstract
One of the issues related to formation flights, which requires to be still discussed, is the stability of formation flight in turns, where the aerodynamic conditions can be substantially different for outer vehicles due to varying bank angles. Therefore, this paper proposes a decentralized control algorithm based on a leader as the reference point for followers, i.e. other UAVs and two flocking behaviors responsible for local position control, i.e. cohesion and repulsion. But opposite to other research in this area, the structure of the formation becomes flexible (structure is being reshaped and bent according to actual turn radius of the leader. During turns the structure is bent basing on concentred circles with different radiuses corresponding to relative locations of vehicles in the structure. Simultaneously, UAVs' air-speeds must be modified according to the length of turn radius to achieve the stability of the structure. The effectiveness of the algorithm is verified by the results of simulated flights of five UAVs.

Published: October 2017

Abstract
This paper proposes the novel technique for analysis of dynamic stress state of multi-connected infinite plates under the action of weak shock waves. For solution of the problem it uses the integral and discrete Fourier transforms. Calculation of transformed dynamic stresses at the incisions of plates is held using the boundary-integral equation method and the theory of complex variable functions. The numerical implementation of the developed algorithm is based on the method of mechanical quadratures and collocation technique. For calculation of originals of the dynamic stresses it uses modified discrete Fourier transform. The algorithm is effective in the analysis of the dynamic stress state of defective plates.

Authors: Jurkiewicz Andrzej , Kowal Janusz , Zając Kamil 
Published: October 2017

AbstractThe essence of the undertaken topic is application of the continuous sky-hook control strategy and the Extended Kalman Filter as the state observer in the 2S1 tracked vehicle suspension system. The half-car model of this suspension system consists of seven logarithmic spiral springs and two magnetorheological dampers which has been described by the Bingham model. The applied continuous sky-hook control strategy considers nonlinear stiffness characteristic of the logarithmic spiral springs. The control is determined on estimates generated by the Extended Kalman Filter. Improve of ride comfort is verified by comparing simulation results, under the same driving conditions, of controlled and passive vehicle suspension systems.

Authors: Elekné Fodor Veronika , Pájer József 
Published: October 2017

AbstractThe primary research aim was to explore the possibilities of transferring relevant data from information systems and databases required for practical environmental impact assessment. The necessary and adequate data content of environmental impact studies were defined according to legal regulations, expert recommendations as well as available impact studies. Furthermore, the data content of information systems pertinent to environmental impact analysis were investigated in view of data transmission. Disposing of the primary data required for impact studies, the classification of environmental objects (object class, object group, object type) was performed. Based on the latter, a pattern system design was completed; in the course of developing this, we defined the individual system overlays in the theoretical model, then assigned properties of the individual object types in the database model.

Authors: Deep Shumank , Asim Mohd , Khan Mohd Kashif 
Published: October 2017

Abstract
Practically speaking, not all real estate construction projects are accomplished in the defined span and within budget. Various factors responsible for occurrence of delays are one of the long-standing issues in the field of real estate. Delays make contractors endure productivity loss, cause high disturbance expenses, and prolongation costs. The aim of the research is to summarize several delay causing factors, which are observed in the execution of previous real estate construction projects. It then proposes implementation of standard prevention procedures to minimize delays. Time effect examination is the approach to evaluating and allotting the upshots of delays or changing a venture schedule. This review sets execution framework of the two sub-principles of the Toyota Way attributes known as philosophy sub-principles and process subprinciples to guide real estate construction businesses in their lean change to delay free real estate construction work. These are implemented after investigating the critical factors responsible for delays in the delayed projects by comparing their as-planned schedules with the adjusted schedules. Methods used in the research include structured surveys and content analysis, which is performed after collection of quantitative data from the respondents. The lean construction principles will be designed and provided to clients to be productive in performing work packages on their scheduled time with minimum possibility of time overrun.
Informal Planning in Depopulating Rural Areas
Authors: Syssner Josefina , Meijer Marlies 
Published: October 2017

AbstractPlanning research has increasingly recognised that planning in depopulating areas differs from planning in growth areas. Several studies have sought to identify planning theories and strategies that are capable of meeting the challenges presented by depopulating areas. However, most of these studies and strategies are based on dense urban environments. This paper seeks to add to planning theory and practice by focusing on informal planning practices in rural depopulating areas. Starting from a resource-based view, the paper introduces an analytical framework that allows a systematic examination of the resources that are generated through informal planning practices in such areas.
Rural Architectural and Planning Forms as a Source of Diversity for Urban Environment (Case Study of Moscow)
Authors: Savchenko Alexander , Borodina Tatiana 
Published: October 2017

Abstract
Inclusion of specific rural architectural and planning forms in the urban structure of Moscow is analysed. As a theoretical background, theories of Garden-Cities (Howard, 1902), Rural-urban continuum (Sorokin, Zimmerman, 1929), Slow city (Mayer, Knox, 2009) are considered. Inclusion of rural architectural and planning forms is analysed for different structural elements of Moscow’s urban environment – public spaces, industrial areas, residential areas, street and road network. Authors argue that once included into the structure of the city, rural planning and architectural forms do not disappear, but after the termination of the implementation of their parent species and ways of life, which are really related to agriculture and other “non-urban” activities, they are transformed for integration into urban life and the environment, contributing to an increase in their diversity. This pattern can be traced consistently, at least, from the XVIII century.
The state of crowns of black alder (Alnus glutinosa (L.) Gaertn.) in Kampinos National Park (Central Poland) in years 2015–2016 – preliminary studies
Authors: Tyburski Łukasz , Przybylski Paweł 
Published: October 2017

Abstract
During 2015 and 2016, in the Kampinos National Park (KNP), monitoring was conducted for the population of black alder (Alnus glutinosa (L.) Gaertn.), which occupies 12.5% of the tree stands in the park and, after the Scots pine (Pinus sylvestris L.), is the second most important species there. The aim of the observation was to obtain data about the current condition of alder in the National Park. Monitoring was carried out on eight plots designated throughout the park. Stands where alder was not the dominant species were omitted. On each plot, 20 trees were evaluated with a total of 160 plants assessed. The age of the tree stands analysed was 55–120 years. Monitoring was conducted by assessing the tree’s crowns, based on the methodology of forest monitoring implemented by the National Environmental Monitoring. Based on the analyses, it was found that the average defoliation of alder in 2015 reached 28.1%, and 34.4% in 2016, with the differences being statistically significant. Among 70% of the specimens, there was no discoloration of the assimilation apparatus. There were significant differences in defoliation between research plots located inside the park and near its borders, which can be associated with the influence of anthropogenic factors. Based on the monitoring, it was found that the state of alder crowns in KNP is a warning or average, depending on the year of observation. Therefore, it is necessary to continue monitoring the state of alder crowns in KNP. On the basis of the study results, it was also found that the biosocial structure of the researched tree stands is formed correctly. The dendrometric measurements conducted show that the average diameter of the trees analysed, at breast height was 30.5 cm with an average height of 25.5 m. To analyse the changes in height and breast height, dendrometric measurements must be repeated in 2020. Monitoring will be continued in the following years to observe the changes.

Authors: Panek Rafał , Wdowin Magdalena , Bandura Lidia , Wisła-Walsh Ewa , Gara Paweł , Franus Wojciech 
Published: October 2017

AbstractThis paper presents the possibility of receiving the granular forms of a zeolitic material of the Na-P1 type obtained from high-calcium fly ash in a semi-technical scale by means of three compacting techniques. The compaction process was carried out using cement, molasses and water glass as binders. Each of the proposed compacting methods affected the textural parameters of the obtained granular zeolite forms, as well as the binders used. In comparison to the other binders it was found that the cement binder had the smaller impact on the values of the textural parameters of the obtained compacted zeolite forms. The surface area for the zeolite Na-P1 was 98.49 m2·g-1, for the cement as a binder was 69.23 m2·g-1, for the molasses was 52.70 m2·g-1and for the water glass was 40.87 m2·g-1. For this reason, the briquetting and extruding tests were carried out using cement as a binder.
Current Stage of Knowledge Relating to the Use Ferruginous Sludge From Water Treatment Plants – a Preliminary Review of the Literature
Authors: Wołowiec Magdalena , Bajda Tomasz 
Published: October 2017

Abstract
In water treatment plants, a large amount of wastewater and sludge is generated during the processing of drinking water. The composition of the sludge is determined by the type and raw water chemistry, as well as the methods and materials used for purification. The major components of the sludge are iron and manganese oxyhydroxides. In the past, the sludge was landfilled, but for environmental reasons it became necessary to find uses for the sludge. The aim of this study was to identify examples of using this sludge. Nowadays, the sludge is applied in the treatment of municipal wastewater, agriculture, and the production of cement and bricks, among others. Attention was also paid to the possibility of using the water processing sludge in different sorption applications.
Optimization of Novel Sorbents for CO2Removal Based on FTIR and TG Analysis
Authors: Majchrzak Anna , Nowak Wojciech 
Published: October 2017

Abstract
Adsorption is considered as one of the most promising technologies for CCS. Gas adsorption involves the separation of gaseous components from flue gas using solid adsorbents. The gaseous component, adsorbate, is adsorbed from the gas phase on a solid material. Regarding CO2adsorption, it is important to consider the parameters, that is the high sorption capacity, CO2selectivity, regeneration and stability in multiple cycles. New directions for the development of adsorbents are focused on increasing their capacity - for this purpose, amine impregnation is carried out. This paper presents a new approach to obtaining mesoporous material from fly ash and, based on this, a new physico-chemical adsorbent obtained by impregnation. The effectiveness of the process was confirmed by thermogravimetric analysis and FTIR infrared spectroscopy.

Halloysite Composites with Fe3O4Particles: The Effect of Impregnation on the Removal of Aqueous Cd(II) And Pb(II)
Authors: Maziarz Paulina , Matusik Jakub 
Published: October 2017

Abstract
In this study, halloysite-Fe3O4composites were synthesized by a chemical-precipitation method to facilitate magnetic separation of the sorbents from aqueous solution. The research focused on the effect of Fe3O4phase on the halloysite sorption properties. The X-ray diffraction (XRD) results confirmed successful deposition of Fe3O4particles on a halloysite surface. They showed that the coating with Fe3O4particles enhanced the halloysite adsorption affinity toward Cd(II) and Pb(II). The highest adsorption capacity was determined for the composites having 10% of the surface deposited with Fe3O4. In this case, the adsorption capacity for Cd(II) and Pb(II) was 33 and 112 mmol·kg-1, respectively. The point of zero charge (pHPZC) and desorption results indicated that the removal mechanism of metals is mainly related to chemisorption involving reaction with hydroxyls of either halloysite or Fe3O4phase. The ion exchange is of limited importance due to the low cation exchange capacity (CEC) of halloysite - Fe3O4composites.

Published: October 2017

Abstract
In Poland, by 2020 430,000 Mg of hazardous waste will be formed annually by the combustion of waste. This waste must be properly managed so as not to endanger the environment. One promising way to manage selected waste is to process it in the synthesis of materials characterised by sorption properties. The results presented in this paper concern the possibility of producing sorbents from waste materials marked with codes 190112 and 190114, which came from two waste incineration plants in Poland. Alkaline activation was performed using two methods: a) hydrothermal, in a solution of 8 M NaOH at 75°C for 24 h; and b) in an autoclave, using a solution of 2 M NaOH at 140°C for 6 h. XRD analyses led to the identification of materials after synthesis of the following zeolite phases: analcime, chabazite and thomsonite. chabazite and analcime can be valuable absorbent materials.

Authors: Muir Barbara , Wołowiec Magdalena , Bajda Tomasz , Nowak Paulina , Czupryński Piotr 
Published: October 2017

Abstract
The use of zeolites as sorbents has been investigated as a replacement for existing costly methods of removing organic contaminants from water solutions. Zeolites can be modified by inorganic salts, organic surfactants, metals or metal oxides in order to increase their adsorption capacity. The unique ion exchange and adsorption properties of zeolites make them very suitable for application in the removal of organic compounds such as volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), phenols and other complex petrochemicals. Many different studies have demonstrated their effectiveness in reducing the concentrations of organic contaminants as well as petroleum derivatives in water, which has been summarized in this paper.

Abstract
This article discusses the impact of choosing a data preprocessing method for the calculated gas density necessary to determine the sorption capacity of a material. The sample of gas-bearing shale was subjected to a volumetric sorption test. The obtained data, pressure and temperature were preprocessed by three methods: moving average, polynomial regression and locally weighted scatterplot smoothing. The results include the excess and absolute sorption calculated from data that were filtered, and data without pre-treatment and Langmuir isotherms’ coefficients for every case.
Applying the Repertory Grid Method for Technology Forecasting: Civil Unmanned Aviation Systems for Germany
Authors: Eimecke Jörgen , Baumert Katrin , Baier Daniel 
Published: October 2017

Abstract
Multistage expert surveys like the Delphi method are proven concepts for technology forecasting that enable the prediction of content-related and temporal development in fields of innovation (e.g., [1, 2]). Advantages of these qualitative multistage methods are a simple and easy to understand concept while still delivering valid results [3]. Nevertheless, the literature also points out certain disadvantages especially in large-scale technology forecasts in particularly abstract fields of innovation [4]. The proposed approach highlights the usefulness of the repertory grid method as an alternative for technology forecasting and as a first step for preference measurement. The basic approach from Baier and Kohler [5] is modified in-so-far that an online survey reduces the cognitive burden for the experts and simplifies the data collection process. Advantages over alternative approaches through its simple structure and through combining qualitative and quantitative methods are shown and an adaption on an actual field of innovation – civil drones in Germany – is done. The measurement of a common terminology for all experts minimizes misunderstandings during the interview and the achievement of an inter-individual comparable level of abstraction is forced by the laddering technique [6] during the interview.

Published: October 2017

Abstract

Background: Chronic kidney disease (CKD) is an emerging health problem in both developed and developing countries. Depression, anxiety and sleep disturbances are highly prevalent in patients with chronic disease, but remain undertreated despite significant negative consequences on patients’ health. Assessment of key components of mental health early in disease course will help to identify high risk subjects in whom modifying these predictors will help in providing active and healthy life in CKD patients.

Methods: We did a cross sectional study in 200 patients of CKD stage III to V-D fulfilling the eligibility criteria who were on follow up in a single tertiary care center in the state of Haryana, India. We assessed the prevalence of anxiety, depression and insomnia and their correlation with demographic variables in these patients. The structured questionnaire used in this study gathered information on respondent demographic and disease characteristics, and information obtained from the HADS and PSQI questionnaire. Factors associated with anxiety, depression and insomnia were examined by a multiple logistic regression analysis.

Results: The prevalence of anxiety, depression and insomnia were found to be 71%, 69% and 86.5% respectively. As the CKD stage advanced, the prevalence as well as severity of these parameters increased. Anxiety, depression and sleep quality were found to be significantly correlated to unemployment, low income, low education, urban residence and presence of co-morbidities. The anxiety, depression and insomnia scores were found to have a strong negative correlation with eGFR, hemoglobin, serum calcium (p <0.01) and a positive correlation with TLC, blood urea, serum creatinine and serum phosphate (p <0.05).

Conclusion: We observed a high prevalence of anxiety, depression and insomnia in CKD patients. There is a need to develop strategies to accurately identify “high risk” subjects who may benefit from preventive measures before complications occur. By identifying CKD patients with high risk of developing these mental health related issues, healthcare provider may be better able to ensure the provision of appropriate rehabilitation to this population.
