Published: July 2019

Abstract
Lake Mellah close to the Mediterranean Sea in north-eastern Algeria belongs to valuable ornithological sites with numerous, often migratory, birds. To achieve the research goal, seventeen (17) sampling points were sampled based on the urbanization of the watershed. Water samples were taken at different wadis levels (upstream and downstream of settlements), as well as at the wastewater treatment plant and in Lake Mellah based on four measurement campaigns conducted at one frequency seasonal (high water, low water) during the year (2011/2012). Biological parameters (coliform faecal bacteria, streptococci) were analysed in water of the lake and its affluents in the laboratory of the Department of Health and Population, El Taref by the most probable number (MPN) technique of the Mac Grady table taken from various points. Obtained results were processed by the use of Bourgeois ratio (coliform faecal bacteria: streptococci) to indicate the origin of faecal contamination of waters and to establish maps of the spatio-temporal evolution of this ratio by the software Surfer 9. This way we obtained information of contamination of human origin during the dry season coming from domestic waste waters. In winter the ratio showed animal prevalence of contamination coming primarily from Animal Park in El Kala.
Multi-phase flow assessment for the fermentation process in mono-substrate reactor with skeleton bed
Authors: Wałowski Grzegorz 
Published: July 2019

Abstract
The selected techniques were reviewed and their technological aspects were characterized in the context of multi-phase flow for biogas production. The conditions of anaerobic fermentation for pig slurry in a mono-substrate reactor with skeleton bed were analysed. The required technical and technological criteria for producing raw biogas were indicated.
Design and construction of the mono-substrate model, biogas flow reactor, developed for cooperation with livestock buildings of various sizes and power from 2.5 kW to 40 kW. The installation has the form of a sealed fermentation tank filled with a skeletal deposit constituting a peculiar spatial system with regular shapes and a rough surface.
Incorporating a plant in such a production cycle that enables the entire slurry stream to be directed from the cowshed or pig house underrun channels to the reactor operating in the flow mode, where anaerobic digestion will take place, allows to obtain a biogas.
The paper presents preliminary results of experimental investigations in the field of hydrodynamic substrate mixing system for biogas flow assessment by the adhesive bed in the context of biogas production. The aim of the study was to assessment and shows the influence of the Reynolds number on the biogas resistance factor for the fermentation process in mono-substrate reactor with adhesive deposit. The measurement results indicate a clear effect of the Reynolds number in relation to the descending flow resistance coefficient for the adhesive bed.
Knowledge, Input-Output Complexity and the Notion of Sustainability
Authors: Sušnik Urban , Sušjan Andrej , Hrovatin Nevenka 
Published: July 2019

Abstract
The paper attempts to synthesize the analytical nucleus of classical political economy and modern ecological economics. In essence this means making a connection between social issues of income distribution, accumulation of capital and economic growth with biophysical limits to economic development. We first model a simple growing system of production and explore its potential to maintain sustainability when using a single natural resource. Taking into consideration the laws of thermodynamics we show that the long-term sustainability of such a simple system is unlikely. When the model is extended to incorporate a wider range of inputs used and commodities produced, such complexity accompanied by knowledge-based structural changes provides necessary conditions for the long-run sustainability of a growing economic system. Since input-output complexity results from the division of labour on the one hand and from intentional R&D policies on the other, this conclusion also brings forward some policy implications regarding income distribution in the society.

The results of the sequence analysis of weight components from descending order as follows: Cognitive for profession skill (CP)=.96 Interpersonal relationship and responsibility skill (IR)=.89 In numerical communication and information technology skill(NC)=.87 Profession future of Thailand skill (PF)=.85 Knowledge for Professional practice skill (KPP)=.73 Moral and ethical skill (ME) =.67.
Designer Competency of the Fashion Design Undergraduate Students in Thailand: A Need Assessment Perspective
Authors: Boonthon Kornchanok , Ratanaolarn Thanin 
Published: July 2019

Abstract
This study used a mixed approach research design. The objectives were to study employers’ and college instructors’ needs regarding the designer competencies of undergraduate fashion-design students in Thailand, and to propose a guideline for the development of designer competencies of undergraduate fashion-design students in Thailand. For the quantitative approach, the research samples included 250 business owners/designers and 163 college instructors from fashion design faculties in Thai universities. A questionnaire was used as the research instrument. Data were collected by email. A “need-assessment analysis” technique was implemented in the data analysis. Regarding the qualitative approach, 15 key informants were interviewed via the interview script. A “content analysis” technique was used to analyse the qualitative data in this research. The results revealed that the employers’ need for improved components of knowledge competencies was consistent with the need of college instructors: both placed a priority on the development of language knowledge, followed by product-management knowledge, innovative knowledge and design knowledge. The employers’ need for improved components of skill competencies was consistent with the need of college instructors: both placed a priority on the development of language skills, followed by product-management skills, innovative and technology skills, and design skills. The employers’ need for improvement of qualification competencies was consistent with the need of college instructors: both placed a priority on the social role, followed by inner drive and self-conceptualisation, respectively. However, the findings indicated a difference between their needs: employers found that none of the qualification competencies needed rapid development, whereas college instructors indicated that one component needed rapid improvement – the social role.
Drivetrain Noise of The Gyroplane I-28
Authors: Cieślak Sławomir , Krzymień Wiesław 
Published: July 2019

Abstract
Gyroplanes, as ultralight aircraft, are popular transport vehicles recently. Ultralight aircraft flights take place at a low altitude – their noise is not without effect on people and nature. The localization of the sources of noise and a possibility to decrease the noise of an gyroplane are described in this paper. The rules of design and exploitation of gyroplanes do not define the limits of emitted noise.
Gyroplanes are not noisy aircraft vehicles but for their silencing the knowledge about the sources and frequency range of noise is necessary. The goal of the conducted measurement was to determine the gyro-plane noise properties and the noise measurement methods. The evaluation of the noise sources was made by acoustic beamforming and the directional emission with single microphones at various engine speeds.
The supplement of these tests should be the rotor noise measurement but that investigation should be performed on a special stand, on which the rotor propulsion noise would not disturb the measurement.
Flow Control on Helicopter-Rotor Blades Via Active Gurney Flap
Authors: Stalewski Wieńczysław 
Published: July 2019

Abstract
The Active Gurney Flap (AGF) is a small, flat tab cyclically deployed and retracted at lower surface of the rotor blade near its trailing edge. It is expected that the device may improve performance of modern helicopters. The main goal of presented investigations was to develop research methodology and next to use it in studies on phenomena occurring in the flow around helicopter-rotor blades equipped with AGF. Conducted CFD simulations aimed at validation of the developed methodology as well as at significant supplementing and extension of results of experimental research. Simplified sensitivity analysis has been conducted aiming at determination of geometric and motion-control parameters of the AGF, optimal from point of view of helicopter-performance improvement. Fully three-dimensional simulations of the rotor flight aimed at determination of flight conditions, in which the use of Active Gurney Flaps could significantly improve the rotorcraft performance.
Experimental Verification of Numerical Calculations with the Use of Digital Image Correlation
Authors: Bajurko Piotr , Dobrzański Przemysław 
Published: July 2019

Abstract
The article presents the results of research work performed under the TEBUK project, aiming primarily to develop a reference methodology for assessing the impact of damage on the strength of structures made of carbon epoxy prepregs. The tests described in the paper were concerned with a fragment of the structure (FS) of the TEBUK project demonstrator, made of carbon epoxy composite, with an artificial circular delamination measuring 40 mm in diameter. Numerical and experimental test of FS have been performed under quasi-static compression load. The buckling of the skin observed in the delamination area, as well as the propagation of the latter were investigated. The numerical calculations have been performed with the use of the commercially available MSC Marc/Mentat calculation suite based on the Finite Elements Methods. Results of the numerical calculations have been compared with experimental measurements made with the use of the Digital Image Correlation (DIC) method. The tests performed aimed to provide a preliminary verification of the numerical model. The results obtained have shown a very good correlation between the numerical and experimental results concerned with critical load levels at which stability of the layers separated by delamination is lost (buckling). The lack of convergence of the numerical model’s results after exceeding the critical load values has rendered it impossible to unequivocally compare the results concerned with propagation of the delamination area.

Authors: Konieczka Robert 
Published: July 2019

Abstract
In the article, the author presents the wide-scale use of Mi-2 helicopters in the different entities subordinated to the Minister of Interior - from the introduction of the design, until the present. Insights are presented pertaining to the early stages of the helicopter’s service life within the structures of the 103rd NJW MSW Aviation Regiment in the 1960s. The article describes selected aspects related to the introduction of the design, training, operational use and problems encountered. The service life of Mi-2 helicopters operating within the structures of the Ministry of Interior ended upon liquidation of the Ministry’s Aviation Detachment. That is when another chapter in the history of the helicopters was started, this time operated within the structures of the Police and Border Guard forces, where their service life has not been fully used up until this day. The paper describes the reality of every-day use to perform specific tasks, presents the location of aerodromes, touches upon a shift in the philosophy behind the use of the helicopters, and describes their strong and weak points. The PZL-Kania helicopter has been also presented, being a modernized version of the Mi-2, and still used in Poland within the aviation forces of the Ministry of Interior and Administration.

Published: July 2019

Abstract
This work presents selected results of I-31T propulsion flight tests, obtained in the framework of ESPOSA (Efficient Systems and Propulsion for Small Aircraft) project. I-31T test platform was equipped with TP100, a 180 kW turboprop engine. Engine installation design include reverse flow inlet and separator, controlled from the cockpit, that limited ingestion of solid particulates during ground operations. The flight tests verified proper air feed to the engine with the separator turned on and off. The carried out investigation of the intake system excluded possibility of hazardous engine operation, such as compressor stall, surge or flameout and potential airflow disturbance causing damaging vibration of the engine body. Finally, we present evaluation of total power losses associated with engine integration with the airframe.

Published: July 2019

Introduction: TB is considered one of the opportunistic infection among PLHIV. The increasing burden of HIV/TB co-infection among key population cause problem to maintain adherence to ART and DOTS services. The emergence of MDR-TB is one of the greatest challenge to control and management of both diseases. However, having knowledge and information of both diseases are important role to access the available HIV/TB services.
Methods: A cross-sectional survey was conducted among key population who had HIV/TB co-infection in two-epidemic zone of Nepal. A pretested semi-structured questionnaire was used to collect data. ANOVA test was done to analyze the collected data by using SPSS version 20.0.
Results: A total of 343 HIV/TB co-infected individuals were enrolled to the study. Most of participants were from ART and DOTS clients. Therefore, the study found that there was significance difference found between knowledge about TB (F=4.400, p= 0.005), causative agent of TB (F=3.160, p=0.025), risk of TB illness among PLHIV (F=8.491, p=0.001) and among key affected population. Moreover, there was significance difference found between access to OI treatment (F=5.113, p=0.002) and access to viral load (F=4.642, p=0.003) among key study population. In gender perspective, there was no significance difference to use and access to available HIV/TB services.
Conclusion: The general knowledge on HIV/TB co-infection was significant association with key population. The knowledge on HIV/TB and access to NGOs’ help can significant effect to access the available HIV and TB services.
