Authors: Chuprуna G. N.
Published: March 2019

We studied the quality of life (QoL) in patients with multiple sclerosis (MS) with the SF-36 compared to the control groups and in terms of comorbidity, as well as to determine the correlation between QoL and the degree of disability, the level of severity of fatigue, depression, pain, disorders of cognitive functions. The study involved 205 MS patients with different forms of course and 157 people made up the control group. Evaluated the clinical and demographic characteristics of the patients with MS due to comorbidity, determines the level of disability (EDSS), severity of pain (VAS), the severity of fatigue (FSS), depression (BDI-II), cognitive impairment (MMSE), quality of life ( SF -36 One or more concomitant disease was detected in 102 (49.3%) patients with MS, there was no co-morbidities in 105 (50.7%) patients with MS. It has been found that in patients with MS I and II groups QoL were significantly lower compared with controls both the individual scales, and by generalized indicators. Also found that during the correlation analysis between QoL and data EDSS, FSS, BDI-II, VAS and MMSE in patients with MS I and II the closest correlations were observed between the indices of quality of life and EDSS, and the least close - between QoL and MMSE. The most informative in establishing correlations between QoL and data EDSS, FSS, BDI-II, VAS and MMSE in patients with MS I and II according to our information was the scale of VT and generalized indicators MH and PH, and the least informative - the scale of GH. Also, it was found that the maximum reduction of generalized QoL in patients with MS group II (relative to the average for the group II) was associated with policomorbidity.
Justification of the using of the method of air reconnaissance of area of intensive application of mine weapons

Published: March 2019

The article is devoted to the analysis of the current state of mine protection that concerns troops, it is a set of measures carried out by all types and branches of troops, and it is aimed at protecting personnel and military equipment from mine weapons. One of the ways to increase mine protection of troops is to enlarge the efficiency of informing the troops about the mine situation directly in the area of combat operations. Therefore, the timeliness of carrying out activities for the search, identification, fixation of explosive objects in the ground, as well as the timely collection and communication to relevant officials and departments of this information is the main goal of engineering intelligence in areas of intensive mine warfare. One of the ways to improve the effectiveness of engineering intelligence is to introduce the practice of identifying mine-explosive barriers and countering the enemy sabotage, reconnaissance forces and illegal armed groups that install them in order to establish new ways of conducting intelligence. The methods are based on the using of modern means of obtaining, processing and promptly bringing intelligence data about the mine situation. So a significant increasing of the intelligence capabilities of engineering units is possible through the using of unmanned aerial vehicles. When units are equipped with such devices, it becomes possible to move from an object-based method of conducting reconnaissance to a more efficient one — a zonal one, the essence of which lies in certain subunits of intelligence in areas of responsibility. This will allow the intelligence units to introduce continuous monitoring of the terrain with its full coverage, carrying out maneuvers, if necessary, largely by means, not forces. It will lead to increase effectiveness of the using of engineering reconnaissance units, their full coverage of the operation band, a reduction in the time management cycle of exploration and the achievement of a high degree of efficiency in providing information to the commanders on the mine situation.

PENERAPAN KANTONG PLASTIK BERBAYAR SEBAGAI UPAYA MEREDUKSI PENGGUNAAN KANTONG PLASTIK
Authors: Astuti Arieyanti Dwi
Published: March 2019

ENGLISHThe use of plastic bag tends to increase and it causes the increase of plastic waste. Plastic waste is a hazardous material because it is difficult to be decomposed biologically. Waste management in Indonesia is regulated by Law Number 18/2008 and Government Regulation Number 81/ 2012. Besides the use of biodegradable plastics, reducing the number of plastic bag can be done by implementing a no free plastic bag policy. The policy was issued by the Directorate General Waste Management, Waste and Hazardous and Toxic under the Ministry of Environment and Forestry (KLHK). The content of this policy is to urge people to bring their own bag when shopping, otherwise they have to buy plastic bags. The policy has been implemented in several countries and succeeded in reducing the number of plastic bags significantly. In Indonesia, the pilot implementation of the policy was conducted from February 21, 2016 to June 5, 2016 in 22 cities. Funds raised from the sale of plastic bag are public funds that will be used for waste management activities. By implementating this policy is expected to reduce the use of plastic bag in Indonesia, as in other countries that already have implemented it. INDONESIAPenggunaan kantong plastik yang cenderung mengalami peningkatan, akan meningkatkan jumlah sampah plastik. Sampah plastik merupakan sampah berbahaya karena sifatnya yang sulit terurai secara biologis. Pengelolaan sampah di Indonesia sudah diatur dalam UU No 18 Tahun 2008 dan PP No 81 Tahun 2012. Selain dengan penggunaan plastik biodegradable, penurunan jumlah penggunaan kantong plastik dapat dilakukan dengan menerapkan kebijakan kantong plastik berbayar. Kebijakan ini dikeluarkan oleh Kementerian Lingkungan Hidup dan Kehutanan (KLHK) melalui surat edaran Direktorat Jenderal Pengelolaan Sampah, Limbah dan Bahan Berbahaya dan Beracun. Isi dari kebijakan ini menghimbau masyarakat untuk membawa alternatif kantong plastik saat berbelanja atau jika masyarakat tidak membawa kantong plastik belanjaan, pelaku ritel akan mengenakan harga pada kantong plastik yang diminta masyarakat saat belanja. Kebijakan ini sudah banyak diterapkan di beberapa negara dan berhasil menurunkan jumlah penggunaan kantong plastik secara signifikan. Di Indonesia, uji coba penerapan kebijakan ini dilakukan mulai 21 Februari 2016 hingga 5 Juni 2016 di 22 kota. Dana yang terkumpul dari hasil penjualan kantong plastik merupakan dana publik yang nantinya digunakan untuk kegiatan pengelolaan sampah. Dengan penerapan kebijakan ini diharapkan dapat mengurangi penggunaan kantong plastik di Indonesia, seperti pada negara-negara lain yang sudah menerapkan kebijakan ini sebelumnya.

Metaheuristic Approach of Multi-Objective Optimization during EDM Process
Authors: Bose Goutam Kumar , Pain Pritam
Published: March 2019

In modern-day manufacturing Electric Discharge Machining (EDM) process has successfully placed itself in the domain of precision machining and generating complex geometries where secondary machining processes are eliminated. In this research paper, a die sinking EDM is applied to machine mild steel in order to measure the different multi-objective results like Material Removal Rate (MRR) and Over Cut (OC). This contradictory objective is accomplished by using the control parameters like a pulse on time, duty factor, gap current and spark gap employing copper tool with lateral flushing. Here the individual objective function of the responses is created through regression analysis. Primarily the contradictory objectives are optimized by employing Taguchi Methodology, then Regression analysis is done on the test results. Additionally, the experimental results are optimized using Response Surface Methodology (RSM). It is followed by a multi-objective optimization through Overlaid contour plots and Desirability functions to ascertain the best parametric combination amongst the set of feasible alternatives.

Published: March 2019

The biggest key aspect to the success of a business is a satisfied customer. For this reason, it is possible to state that the growing trend of focusing on the customer and his/her needs has prevailed in recent years. The aim of this article is to analyze the use of CRM (Customer Relationship Management) systems in small- and medium-sized enterprises (SMEs) in the Czech Republic and to find the determinants for CRM system implementation. The best practice for CRM implementation suitable for SMEs is clarified using a specific case of a global enterprise. A fully functional CRM system can be considered a competitive advantage, and this is not only the case for global companies, but also for small and medium enterprises. Using a functional CRM interconnected with an ERP system, enterprises are able to manage business and direct marketing activities, as well as the company’s overall profits. These functional systems lead to an integrated system called funnel management, which improves customer relationship management and leads to a sustainable business.
Verification of Boundary Conditions Applied to Active Flow Circulation Control
Authors: Vrchota Petr , Prachař Aleš , Hospodář Pavel
Published: March 2019

Inclusion of Active Flow Control (AFC) into Computational Fluid Dynamics (CFD) simulations is usually highly time-consuming and requires extensive computational resources and effort. In principle, the flow inside of the fluidic AFC actuators should be incorporated into the problem under consideration. However, for many applications, the internal actuator flow is not crucial, and only its effect on the outer flow needs to be resolved. In this study, the unsteady periodic flow inside the Suction and Oscillatory Blowing (SaOB) actuator is analyzed, using two CFD methods of ranging complexity (URANS and hybrid RANS-LES). The results are used for the definition and development of the simplified surface boundary condition for simulating the SaOB flow at the actuator’s exit. The developed boundary condition is verified and validated, in the case of a low-speed airfoil with suction applied on the upper (suction) side of the airfoil and oscillatory blowing applied on the lower (pressure) side, close to the trailing edge—a fluidic Gurney flap. Its effect on the circulation is analyzed and compared to the experimental data.
Agricultural Biodiversity and Ecosystem Services of Major Farming Systems: A Case Study in Yayo Coffee Forest Biosphere Reserve, Southwestern Ethiopia
Authors: Duguma Mezgebu Senbeto , Feyssa Debela Hunde , Biber-Freudenberger Lisa
Published: March 2019

Farming systems, with their concerns of biodiversity, ecosystem services, and productivity and production issues towards progress in human needs, wellbeing, and sustainable development, are challenging in most biosphere reserves. In this study, we assess the levels and trends of the agro-biodiversity and ecosystem services of different farming systems in the Yayo Biosphere Reserve in Ethiopia. Interviews with a total of 120 farmers, 16 key informants, and 12 focal group discussions (FDGs) were conducted, and species composition was assessed based on data collected on ten plots per major farming system. Result indicate that four farming systems, namely homegardens (HG), plantation coffee (PC), semi-forest coffee (SFC), and annual crop production (CP) systems, can be identified. Shannon and Evenness indices were highest in the HG system (H′ = 3.14, E = 0.8), and lowest in the CP system (H′ = 0.71, E = 0.18). Additionally, more diversified and relatively less cultivated farming systems provide more ecosystem services, and land users tend to practice less diversified farming systems in order to increase food supply at the expense of other ecosystem services. Therefore, this study recommends that diversified farming systems need to be considered to conserve or enhance specific ecosystem services in ways that reduce their negative tradeoffs.
Ommatissus lybicus Infestation in Relation to Spatial Characteristics of Date Palm Plantations in Oman

Published: March 2019

The agricultural ecosystem and its interaction with the outside environment plays a major role in the population of herbivores. The infestation of the Dubas bug, Ommatissus lybicus, has shown a spatial and temporal variation among different date palm plantations in Oman. This study focused on the relationship of infestation with date palm cultivation environments. The infestation and some selected environmental factors were evaluated in 20 locations for four consecutive infestation seasons over two years. Ordinary least squares (OLS) regression was used to identify the significant factors and the global relationship. Geographically weighted regression (GWR) was used to determine the spatial relationship. The results showed that GWR had better prediction than OLS. The model explained 61% of the infestation variation in the studied locations. The most significant coefficient was the tree planting pattern, the trees planted in uneven rows and columns (irregular pattern) had a positive effect; the infestation increased as the irregularity increased due to an increase in tree density. This reduced the interaction of harsh outside weather with the date palm plantation microclimate. The proportion of side growing area had a negative effect on insect population; as the percentage of side growing area increased as the infestation decreased, assuming the side growing crops hosted natural enemies. The study concluded that the variation of spatial and temporal infestation was primarily due to the variation of the cultural practices and spatial environment of the date palm plantations.
Apatite Stimulates the Deposition of Glomalin-Related Soil Protein in a Lowbush Blueberry Commercial Field
Authors: Paré Maxime C. , Chagnon Pierre-Luc , Plourde Joanne , Legendre-Guillemin Valérie
Published: March 2019

Many wind-sensitive and unproductive soils could benefit from increased glomalin-related soil protein (GRSP), an operationally defined soil protein pool known to improve soil quality and nutrient storage. We expect at least part of this GRSP fraction to originate from fungal biomass. Although P-rich minerals such as apatite are known to increase C allocation from plants to mycorrhizal fungi, there are no studies directly linking apatite with GRSP. We investigated the effect of apatite on GRSP deposition rates in a cultivated field of wild lowbush blueberry (Vaccinium angustifolium Aiton; Vaccinium myrtilloides Michx.) in the Saguenay‒Lac-Saint-Jean region of Quebec (Canada). A field incubation technique (145 days) using sterilized porous sand bags (50 µm pores) was used to measure in situ easily extractable GRSP (EE-GRSP) deposition rates from bags with (n = 10) and without (n = 10) apatite. Half of the bags (n = 10) were also soaked in Proline® 480 SC (Bayer CropScience, Calgary, Alberta, Canada) (Prothioconazole) to determine if EE-GRSP deposition rates were affected by this commonly applied fungicide. Our results indicated that adding apatite into sand bags significantly increased (+70%) EE-GRSP deposition rates, whereas soaking the bags in fungicide had no significant effect. Although the direct linkage between GRSP and lowbush blueberry plants remains to be detailed, our study reports for the first time GRSP concentrations from lowbush blueberry soils. Implications of these findings are discussed.

Increasing soil carbon stocks in agricultural grasslands has a strong potential to mitigate climate change. However, large uncertainties around the drivers of soil respiration hinder our ability to identify management practices that enhance soil carbon sequestration. In a context where more intense and prolonged droughts are predicted in many regions, it is critical to understand how different management practices will temper drought-induced carbon losses through soil respiration. In this study, we compared the impact of changing soil volumetric water content during a drought on soil respiration in permanent grasslands managed either as grazed by dairy cows or as a mowing regime. Across treatments, root biomass explained 43% of the variability in soil respiration (p < 0.0001). Moreover, analysis of the isotopic composition of CO2 emitted from the soil, roots, and root-free soil suggested that the autotrophic component largely dominated soil respiration. Soil respiration was positively correlated with soil water content (p = 0.03) only for the grazed treatment. Our results suggest that the effect of soil water content on soil respiration was attributable mainly to an effect on root and rhizosphere activity in the grazed treatment. We conclude that farm management practices can alter the relationship between soil respiration and soil water content.

The aim of this pilot study was to document the effects of endurance training at different intensities on heart rate (HR), blood count, serum cortisol, and maximal temperatures of different body locations, namely eye, crown, pastern pasterns, gluteus and longissimus dorsi muscle (mm), measured by infrared thermography technique (IRT) in horses trained for endurance. Possible associations among the studied parameters were also investigated. Our hypothesis was that temperature, measured by IRT after endurance training of different intensities would vary depending on the intensity and would be positively correlated with HR and serum cortisol. Eight horses were tested before and after training of different intensities (low, moderate, and high). The results partially supported our hypothesis; all the studied parameters increased after training (p < 0.05), eye temperature (ET) correlated positively with HR (p < 0.01), and crown temperature (CT) correlated positively with cortisol (p < 0.01). However, only HR and white blood cells increased with the intensity of the exercise (p = 0.0016 and p = 0.0142, respectively). Our findings suggest the evaluation of ET and CT may become a useful non-invasive tool to detect physiological stress during training and to evaluate how the horses cope with the training. Infrared thermography technique may also become a useful tool for the early identification of horses that are not fit to compete or to continue the competition. However, further studies should be conducted on a larger number of horses and during competitions to ascertain our preliminary findings.

During the last years, scientific research in biotechnology has been reporting a considerable boost forward due to many advances marked in different technological areas. Researchers working in the field of regenerative medicine, mechanobiology and pharmacology have been constantly looking for non-invasive methods able to track tissue development, monitor biological processes and check effectiveness in treatments. The possibility to control cell cultures and quantify their products represents indeed one of the most promising and exciting hurdles. In this perspective, the use of conductive materials able to map cell activity in a three-dimensional environment represents the most interesting approach. The greatest potential of this strategy relies on the possibility to correlate measurable changes in electrical parameters with specific cell cycle events, without affecting their maturation process and considering a physiological-like setting. Up to now, several conductive materials has been identified and validated as possible solutions in scaffold development, but still few works have stressed the possibility to use conductive scaffolds for non-invasive electrical cell monitoring. In this picture, the main objective of this review was to define the state-of-the-art concerning conductive biomaterials to provide researchers with practical guidelines for developing specific applications addressing cell growth and differentiation monitoring. Therefore, a comprehensive review of all the available conductive biomaterials (polymers, carbon-based, and metals) was given in terms of their main electric characteristics and range of applications.

The removal of dye from textile industry wastewater using a photo-Fenton like catalyst system was investigated wherein the removal efficiency of phenol and chemical oxygen demand (COD) was studied by varying various parameters of pH (3–11), reaction time (1–50 min), activated Carbon/CoFe2O4 (AC/CFO) nanocomposite dosage (0.1–0.9 g/L), and persulfate amount (1–9 mM/L). The highest removal rates of reactive red 198 and COD were found to be 100% and 98%, respectively, for real wastewater under the optimal conditions of pH = 6.5, AC/CFO nanocomposite dosage (0.3 g/L), reaction time, 25 min, and persulfate dose of 5 mM/L up on constant UV light irradiation (30 W) at ambient room temperature. The result showed that this system is a viable and highly efficient remediation protocol relative to other advanced oxidation processes; inexpensive nature, the ease of operation, use of earth-abundant materials, and reusability for removal of organic pollutants being the salient attributes.

Published: March 2019

The structural stability and magnetic properties of the cubic and tetragonal phases of Mn3Z (Z = Ga, In, Tl, Ge, Sn, Pb) Heusler alloys are studied by using first-principles calculations. It is found that with the increasing of the atomic radius of Z atom, the more stable phase varies from the cubic to the tetragonal structure. With increasing tetragonal distortion, the magnetic moments of Mn (A/C and B) atoms change in a regular way, which can be traced back to the change of the relative distance and the covalent hybridization between the atoms.

Published: March 2019

To alleviate traffic congestion in the city, an integrated waiting area is introduced to the signalized intersection in this paper. After the design idea and the typical form of the integrated waiting area is proposed, the control method at the signalized intersection is discussed. The coordination control process of the main and pre-signal at the signalized intersection with the integrated waiting area is analyzed and modeled. To assess the operational performance of the integrated waiting area at intersections, a microscopic traffic simulation software (VISSIM) is utilized to simulate intersections with and without integrated waiting areas. Key issues concerning signal timing plans are then discussed. With comparisons between the operation of intersections with and without integrated waiting areas, the implementation effect is quantified based on the statistical data of the simulation result. The results confirm the potential benefits of the integrated waiting areas at the signalized intersections and show that integrated waiting areas work best in heavy traffic demand.

The characteristics of partially coherent circular flattened Gaussian vortex beams in turbulent biological tissues are investigated, and the analytical formula for the cross-spectral density of this beam is derived. According to the cross-spectral density matrix, the average intensity and degree of polarization can be obtained. By numerical simulation, the distributions of the normalized average intensity and degree of polarization of partially coherent circular flattened Gaussian vortex beams are demonstrated on the research plane of turbulent biological tissues. The effects of the two beam parameters, the topological charge, the two transverse coherent lengths, and the structural constant of biological turbulence on the normalized average intensity and degree of polarization are analyzed. This study is of great significance for the potential application of partially coherent circular flattened Gaussian vortex beams in medical imaging and medical diagnosis.

In order to expand the range of pot materials for induction cookers, a kind of sandwich structural composite ceramic panel that consists of an Al2O3 ceramic substrate, magnetic heating interlayer, and ZrO2 ceramic substrate was developed by combining the tape casting process and the screen printing process. In this research, the slurry composition of the functional phase, glass powder, and organic carrier was optimized for preparing the heating interlayer with excellent electromagnetic properties. The influences of the glass powder content and the magnetic layer structure on the thermal shock resistance of the composite ceramic panel were studied. The finite element model of the composite ceramic panel under thermal load was established through ANSYS software. In the range of 0.1–0.3 mm thickness of a magnetic heating interlayer, the temperature field and the macroscopic stress field of the composite ceramic panel were simulated, and the influence of the magnetic layer structure on the thermal stress distribution of the composite ceramic panel was analyzed. The experimental results showed that the magnetic layer had the best quality when the amount of glass powder added was 9 wt%. The ANSYS simulation revealed that the gradient structure of the magnetic layer could reduce the stress between the alumina layer and the magnetic layer from 308 to 192 MPa, which significantly improved the thermal shock resistance of the composite ceramic panel. Therefore, the gradient structure of the magnetic layer could ensure the stability of the composite ceramic panel after five cycles of electromagnetic heating.
