Impact of trombe wall construction on thermal comfort and building energy consumption
Authors: Randjelovic Dusan , Vasov Miomir , Ignjatovic Marko , Bogdanovic-Protic Ivana , Kostic Dragan
Published: October 2018

Energy consumption has reached its highest level globally. Buildings have the
largest share in total energy consumption, so designers must take into
account their functioning and the consequences that can arise. Passive solar
design is an imperative in modern architecture, and Trombe wall, as one of
the principles of this design, is certainly distinguished. The paper
presents an overview of the characteristics of the construction of the
Trombe Wall in order to improve thermal stability and reduce energy
consumption in buildings. Starting from the consideration of climatic
influencing factors, through the heat capacity of the materials applied and
their thickness and color of the thermal mass, it is very important to know
in detail all the factors that can lead to the improvement of the efficiency
of this system. The specific heat of the walls in the building, the time
delay, the decrement factor and the influence and position of the thermal
insulation were also taken into account. The effect of glazing as well as
the influence of the ventilation openings were highlighted as significant
elements. On the basis of the analysis of the above components, the
conclusions and guidelines for designing this type of constructions were
made in order to improve the efficiency and reduced energy consumption while
providing adequate comfort in the facility.

Published: October 2018

In this paper we provide an overview of instabilities observed in commercial
power VDMOSFETs subjected to irradiation, NBT stress, and to consecutive
exposure to them. The results have indicated that irradiation of previously
NBT stressed devices leads to additional threshold voltage shift, while NBT
stress effects in previously irradiated devices depend on the gate bias
applied during irradiation and on the total dose received. This points to the
importance of the order of applied stresses, indicating that for proper
insight into the prediction of device behaviour not only harsh conditions,
but also the order of exposure have to be considered. It has also been shown
that changes in the densities of oxide trapped charge and interface traps
during spontaneous recovery after each of applied stresses can be
significant, thus leading to additional instability, even though the
threshold voltage seems to remain stable, pointing to the need for clarifying
the responsible mechanisms.

Authors: Nahirnyj Taras , Tchervinka Kostiantyn
Published: October 2018

The methods of irreversible thermomechanics and functional analysis are used to formulate the mathematical model of thermoelastic solid body taking account of structural heterogeneity of the body material and geometric irregularity of its surface. The density and the chemical potential of skeleton among others are included into the state parameters space. The source of skeleton mass reconciles the actual and reference body states and may be associated with real surface forming method. The analysis of model problem solutions shows that the model is appropriate to describe coupled processes in porous and nanoporous bodies. It allows studying the size effects of strength, elastic moduli, etc. caused by near-surface non-homogeneity.
Simulation Study of the Process of Friction in the Working Elements of a Car Braking System at Different Degrees of Wear
Authors: Borawski Andrzej
Published: October 2018

Among the many elements of a modern vehicle, the braking system is definitely among the most important ones. Health, and, frequently, life, may rest upon the design and reliability of brakes. The most common friction pair used in passenger cars today is a disc which rotates with the road wheel and a cooperating pair of brake pads. The composite material of the pad results in changing tribological properties as the pad wears, which was demonstrated in experimental studies. The change is also facilitated by the harsh operating conditions of brakes (high and rapid temperature changes, water, etc.). This paper looks into how changing tribology reflects on the heating process of disc and pads during braking. And so a simulation study was conducted, as this method makes it possible to measure temperature in any given point and at any time, which is either impossible or extremely difficult in real life conditions. Finite element method analyses were performed for emergency braking events at various initial speeds of the vehicle reflecting the current road speed limits.
The Ethical Dimension of Professional Integrity in the Hungarian Child Protection System
Authors: Bogács Ernő , Rácz Andrea
Published: October 2018

Following a discussion about ethics and social work, in this article, we will present the main results of three researches conducted in the past few years on the Hungarian child protection system. These studies highlight the professional gaps, the prejudiced beliefs related to the primary (children) and secondary (parents) client systems of child protection, the value crisis in professional mentalities, and the crisis of the profession in general. We argue that a change in mentalities and professional treatment in the operational practice requires a thorough reconsideration of the ethical dimensions of child protection to the extent of developing and introducing their own code of ethics. As the helping profession is actively involved in the transformation of the welfare state, in parallel with restructuring welfare conditions, we should reconsider how the scarce methodological framework for practice at the national level can cope with problems and how it can emancipate the clients and serve their well-being. The research results indicate that the direction of development is to create an activating and mobilizing helper system that can preserve the core values of the profession as well as adapt to social changes and reflect on the expectations of the public policy thereof.

Authors: Michalak Bartosz , Eckert Wojciech
Published: October 2018

Stany is a small village located near the town of Nowa Sól in the Lubusz Voivodship. Within a few hundred meters of the buildings there is one of the most interesting monuments in the Lubusz Voivodship - a railway bridge dating back to the beginning of the 20th century. It was designed by the company BEUCHELT & Co. The bridge consists of fourteen spans with a total length of 642 m. It was in continuous operation until 1994. Since then the object has not been used and its technical condition is deteriorating year by year. The bridge is unique in Poland and in Europe, which means that it could be interesting to carefully describe it and investigate its structure. There are plans to repair its structure in the following year. The bridge will not be used in its previous function, but it will be renovated and adapted for cyclists.

Published: October 2018

The aim of the paper was to determine the effectiveness of the removal of 4, 5and 6 - ring PAHs from coking wastewater using sodium percarbonate Na2CO3∙1,5 H2O2 and iron sulphate in acid condition. The samples were exposing to ultraviolet rays. The source of UV-C radiation was a lamp emitting a wave of light with a length of λ = 264 nm, placed directly above the layer of the samples wastewater. The sodium percarbonate Na2CO3 1.5 H2O2 doses were determined on the basis of stoichiometric calculation. Ratio of iron ions to the hydrogen peroxide released in reaction was: 0.5; 0.4; 0.3; 0.2; 0.1. Before and after the oxidation process, COD and TOC value were determined and as well as concentrations of selected PAHs. The total concentration of tested PAHs before oxidation reached the value of 995 μg/L. The average content of organic pollutants determined by the chemical oxygen demand (COD) was 538 mg/L, while the average content of Total organic carbon (TOC) was 180 mg/L. The use of sodium percarbonate caused the oxidation of organic pollutants and lowering of COD and TOC in the following ranges: 22-46% and 10-30%. For individual PAHs the degradation efficiency was in the ranged from 95% to 99.9%. The degradation efficiency of 4 ring hydrocarbons caused 98% and 5 and 6 ring of hydrocarbons was 98.7% and 99.4%, respectively.

Published: October 2018

The authors of the article consider regional labeling as a marketing tool which can contribute to the development of regional activities. These are focused mainly on traditional regional products and products. Their general popularity in prosperous regions is an important source of income for the inhabitants. In the less developed regions, it represents a significant stimulating tool of development. By means of a Slovak region of Gemer-Malohont as an example, the authors bring quantitative findings related to the preference of regional brands. They took into consideration the indicators of age, gender, education, monthly income and locality in connection with preference of regional products. They pointed to the fact that regional labeling has a mobilizing function to link and then jointly present its local activities. The behaviour of the population from the regions is an important recommendation for small producers and producers from less developed regions of Central Europe.
Production improvement in gas condensate reservoirs by wettability alteration, using superamphiphobic titanium oxide nanofluid
Authors: Esmaeilzadeh Pouriya , Taghi Sadeghi Mohammad , Bahramian Alireza
Published: October 2018

Many gas condensate reservoirs suffer a loss in productivity owing to accumulation of liquid in near-wellbore region. Wettability alteration of reservoir rock from liquid-wetting to gas-wetting appears to be a promising technique for elimination of the condensate blockage. In this paper, we report use of a superamphiphobic nanofluid containing TiO2 nanoparticles and low surface energy materials as polytetrafluoroethylene and trichloro(1H,1H,2H,2H-perfluorooctyl)silane to change the wettability of the carbonate reservoir rock to ultra gas-wetting. The utilization of nanofluid in the wettability alteration of carbonate rocks to gas-wetting in core scale has not been reported already and is still an ongoing issue. Contact angle measurements was conducted to investigate the wettability of carbonate core plugs in presence of nanofluid. It was found that the novel formulated nanofluid used in this work can remarkably change the wettability of the rock from both strongly water- and oil-wetting to highly gas-wetting condition. The adsorption of nanoparticles on the rock and formation of nano/submicron surface roughness was verified by Scanning Electron Microscope (SEM) and Stylus Profilometer (SP) analyses. Using free imbibition test, we showed that the nanofluid can imbibe interestingly into the core sample, resulting in notable ultimate gas-condensate liquid recovery. Moreover, we studied the effect of nanofluid on relative permeability and recovery performance of gas/water and gas/oil systems for a carbonate core. The result of coreflooding tests demonstrates that the relative permeability of both gas and liquid phase increased significantly as well as the liquid phase recovery enhanced greatly after the wettability alteration to gas-wetting.
Modifying Methylalumoxane via Alkyl Exchange
Authors: Zijlstra Harmen S. , Joshi Anuj , Linnolahti Mikko , Collins Scott , McIndoe J Scott
Published: October 2018

Methylalumoxane (MAO) ionizes highly selectively in the presence of octamethyltrisiloxane (OMTS) to generate [Me2Al∙OMTS]+ [(MeAlO)16(Me3Al)6Me]–. We can take advantage of this transformation to examine the reactivity of a key component of MAO using electrospray ionization mass spectrometry (ESI-MS), and here we describe the reactivity of this pair of ions with other trialkyl aluminum (R3Al) components. This alkyl exchange reaction bears relevance to the various modified methylalumoxanes (MMAOs) available, which differ from regular MAO in being adulterated with different alkyl groups. We found Et3Al to exchange much faster and extensively (t½ ~ 2 sec, up to 25 exchanges of Me for Et) than iBu3Al (t½ ~ 40 sec, up to 11 exchanges) or Oct3Al (t½ ~ 200 sec, up to 7 exchanges). The exchanges are reversible and the methyl groups on the cation are also observed to exchange with the added R3Al species. These studies are the first to offer concrete insights into the solution transformations of MAO.

Authors: Polyudina R. I. , Potapov D. A. , Kharchebnikov V. V.
Published: October 2018

The paper presents the results of research into breeding of the new cultivar of oil radish Sibiryachka by the method of multiple individual selection during the period 2008-2018. The cultivar of oil radish Tambovchanka was used as an initial material. The studies were conducted in the foreststeppe zone of Western Siberia (Novosibirsk region) in the breeding nurseries laid on fallow by a widerowed method. Well-developed plants were selected in the field conditions, which were then used for selection of the most productive forms for further sowing, on the basis of the thorough laboratory analysis of the components of the seed yield. For comparative analysis the initial standard cultivar Tambovchanka was used. The main attention in the selections process was paid to high seed and feed productivity, early maturity, resistance to main diseases and pests. As a result, after conducting five selection cycles, a complex hybrid population was obtained, which, in the contest trial during three years, showed an advantage over the standard cultivar by seed and dry matter yield, as well as by stability of seed yield. It was submitted for the state cultivar test with the name Sibiraychka. The main economically valuable features of the oil radish cultivar Sibiryachka are as follows: the average yield of green mass is 33.6 tn/ha, seeds – 1.2 tn/ ha, the seed protein content is 28%. The cultivar is early-ripening, so the duration of the growing season is 89-101 days. It reaches mowing ripeness in 59-75 days. The leaf formation of the cultivar is 41-59%. The new cultivar is resistant to major diseases and pests and is intended for fodder and green manure use. The cultivar was included in the State register of breeding achievements suitable for cultivation on the whole territory of the Russian Federation in 2018. The copyright certificate and patent were received.

Published: October 2018

The use of genetic markers in addition to traditional methods of animal selection with desirable genotypes allows to increase the share of animals with high productivity in the next generations and ensures improvement of breeding efficiency. Genetic features of the Prikatun type of the Gorno-Altay semi-fine wool breed of sheep and the white downy goat breed in the Republic of Altay were studied by the method of immunogenetic and molecular genetic analysis. The frequency of antigenic factors was identified and the index of genetic similarity between goats and sheep and their separate herds was calculated. Gene polymorphism of β-lactoglobulin (BLG) and calpastatin (CAST) was revealed by the method of DNA diagnosis. Population and genetic characteristics of the herds was studied by the genes specified. Associative genotype relation to productivity and quality of the produce obtained was analyzed. The index of genetic similarity between the goats and the sheep was at the level of 0.713, between the separate herds of the goats the index was 0.861. The ratio of genotypes in the BLG gene determined by PCR analysis in the white downy goats was S1S1– 16.1%; S1S2– 50.6%; S2S2– 33.3%. In the Prikatun type two genotypes were identified in this gene: BB with the frequency of 59.2%, and AB – 40.8%. Two different alleles were identified in the CAST gene of sheep (M and N). The genotype MM was the predominant variant in the CAST sheep gene, whose frequency was 88%. The frequency of occurrence of animals with NN genotype was 1%, MN – 11%. It was shown that the gene equilibrium in the herds was not broken, χ2= 0.931. It was noted that heterozygous goats (S1S2) by BLG gene had a higher live weight by 0.30-0.61 kg compared to other variants of BLG gene (p<0.05). It was also found that lambs with genotype MM of the CAST gene had a higher live weight by 5.5 kg than MN heterozygotes (p< 0.01). However, this difference was not revealed in other age and sex groups of animals.

Son
yıllarda birçok ülkede doğal bitki türlerinin bitkisel peyzaj tasarımında
kullanımına yönelik eğilim artmaktadır. Ancak fidan evresi ve sürdürülebilir
alan performansı açısından bitkisel materyalin bitki besin elementleri ile
ilişkisinin araştırılmasına ihtiyaç bulunmaktadır. Bu çalışma, bir vejetasyon
dönemi içinde tohumla çoğaltılarak yetiştirilen Celtis australis L. fidanlarının yaprak besin elementi içeriklerine
yetiştirme ortamı ve genotipin etkisini belirlemek amacıyla
yapılmıştır. Çalışmada; torf+kum (2:1 hacimsel), torf+perlit (2:1
hacimsel), tınlı toprak+çiftlik gübresi+kum (2:1:1 hacimsel) ve mantar kompost
atığı+kum (2:1 hacimsel) karışımları yetiştirme ortamı olarak kullanılmış, 5
genotip bu ortamlarda yetiştirilmiş ve ekim ayında sürgünlerin üst orta
bölümündeki olgun yapraklardan alınan örneklerin makro ve mikro besin elementi
içerikleri analiz edilmiştir. Sonuçlar yaprak besin
elementi içeriklerinin büyük bir bölümünün yetiştirme ortamı ve genotipe göre
istatistiksel anlamda önemli farklılıklar gösterdiğini ortaya koymuştur. Makro
besin elementlerinden yaprak azot içeriklerinin % 1.57 ile % 2.20,
fosfor içeriklerinin % 0.08 ile % 0.24, potasyum içeriklerinin % 0.29
ile % 0.52, kalsiyum içeriklerinin % 3.77 ile % 5.09, magnezyum
içeriklerinin % 0.31 ile % 0.74; mikro besin elementlerinden yaprak
demir içeriklerinin 97.76 ppm ile 171.53 ppm, mangan içeriklerinin 23.23
ppm ile 99.56 ppm, çinko içeriklerinin 3.16 ppm ile 8.86 ppm ve bakır
içeriklerinin 2.03 ppm ile 7.43 ppm arasında olduğu görülmüştür. Belirtilen
aralıkların hiçbirinde fidanlarda makro ve mikro besin elementleri görsel
noksanlık/fazlalık (toksik) belirtisi gözlenmemiştir. Bu nedenle değerlerin C. australis türünün yaprak besin
elementi içeriklerinin yeterlilik sınırları hakkında da ön bilgi
oluşturabileceği değerlendirilmiştir.

Published: October 2018

In sampling survey, it was necessary to have sufficient sample size in order to get accurate direct estimator about parameter, but there are many difficulties to fulfill them in practice. Small Area Estimation (SAE) is one of alternative methods to estimate parameter when sample size is not adequate. This method has been widely applied in such variation of model and many fields of research. Our research mainly focused on study how SAE method with binomial regression model is applied to obtained estimate proportion of cultural indicator, especially to estimate proportion of people who appreciate heritages and museums in each regency/city level in West Java Province. Data analysis approach used in our research with resurrected data and variables in order to be compared with previous research. The result later showed that binomial regression model could be used to estimate proportion of cultural indicator in Regency/City in Indonesia with better result than direct estimation method.

VARIABILITY OF NORMALIZED DIFFERENCE VEGETATION INDICES IN SUMATRA AND ITS RELATION TO CLIMATE ANOMALIES(KERAGAMAN INDEKS VEGETASI DI SUMATERA DAN HUBUNGANNYA DENGAN ANOMALI IKLIM)
Authors: Adiningsih Erna Sri , . Kustiyo
Published: October 2018

Indeks vegetasi yang diperoleh dari data NOAA-AVHRR sudah umum digunakan sebagai indikator kehijauan dan kekeringan vegetasi. Kondisi iklim global dan regional diatas Sumatera mempengaruhi indeks vegetasi di Sumatera. Penelitian ini bertujuan mempelajari keragaman indeks vegetasi terutama di Sumatra dan hubungannya dengan El Nino - Southern Oscillation (ENSO) dan Indian Ocean Dipole Mode Event (DME). LAC NDVI periode 1996-2002 digunakan untuk menganalisa koefisien keragaman dan analisis korelasi kanonik. Keragaman NDVI yang tinggi ditemukan di pantai timur, bagian selatan dan bagian utara Sumatera, sedangkan di bagian barat dan tengah keragamannya rendah. Secara keseluruhan, keragaman NDVI selama monsun barat lebih tinggi daripada periode monsun timur. ENSO dan DME mempangaruhi indeks vegetasi di Sumatera pada lag 0,4,dan 5 bulan (nyata pada taraf 5%). Kontribusi terbesar diberikan oleh variable kanonik lag 1 (R2=70.1%), sisa 29,9 % disebabkan oleh keragaman factor-faktor lainnya. Kerana korelasi dan signifikansi dari parameter iklim secara statistik tinggi, maka dapat digunakan sebagai prediktor NDVI di Sumatera. Diantara 6 time lag , parameter dengan lag 6 bulan mempunyai keragaman yang tertinggi. Namun, uji beda nyata menunjukkan bahwz korelasi kanonik pada lag 0,4,dan 5 yang mempunyai beda nyta tertinggi (pada taraf 95%). Struktur korelasi kanonik untuk parameter iklim pada lag 0 dan 1 didominasi oleh SOI dan anomaly SST. Sedangkan korelasi pada lag 2,5, dan 6 didominasi oleh SOI, anomaly SST, dan DMI. Berdasarkan hasil analisis tersebut, kami menyimpulkan bahwa analisis korelasi kanonik merupakan metode yang optimum untuk memprediksi NDVI di Sumatera pada lag 5 bulan menggunakan SOI, SSTA, dan DMI sebagai prediktor. Hasil ini menunjukkan bahwa parameter iklim dapat digunakan untuk memprediksi NDVI 5 bulan ke depan dengan baik di Sumatera.

Many approaches have been applied to forecast climate using statistical and deterministic models using independent and dependent variables empirically. It is more practical to analyze the parameters, but it needs validation anytime and anywhere. Kalman filtering unites physical and statistical model approaches to stochastic model renewable anytime for objective of on line forecasting. Based on research, sea surface temperature Nino 3.4 have high correlation with rainfall in Indonesia, so it is used to forecast rainfall in Cirebon as area study. Rainfall clustering in Cirebon results 6 groups with rainfall average 1400-1500 mm/year for dry area and 3000-3200 mm/year for wet area. Validation have correlation coefficient validation value more than 94%, correlation coefficient model value more than 78% and fit model value more than 38%. The result of regression gives R2 value of more than 0,8. It implies that predicting model using Kalman Filter is feasible to forecast montly rainfall based on sea surface temperature Nino 3.4. The result of rainfall prediction in Cirebon show increasing in rainfall until February 2005, with correlation coeficient value of model more than 90% and fit model more than 40%.

Published: October 2018

The upper Ciliwung watershed is one of the critical catchments areas in Java Island. A major element of this area is the modification of natural land-cover due to human activities. Land use change is driven by the interaction between physical and socio-economic factors. The objective of this paper is to develop a land use change model and to evaluate runoff volume based on land use prediction. The pseudo-R2 or 2 in this model is 51.7% and the calibration between predicted land use and the real is 65.5%. The analysis result of land use change for period 2005-2010 and 2015-2020 show a special change pattern. In the first period, the forest land will decrease by 85%, while resettlements land increase by 144%, so the Curve Number value will increase from 80 to 81. These indicate decreasing capability of the upper Ciliwung to retain rainfall. The impact of this condition will increase runoff volume from 660.000 m3 to be 905.000 m3. In the second period, the forest and resettlements land will increase by 612% and 28%, so the Curve Number will decrease from 80 to be 78. This will decrease runoff volume from 805.000 m3 to be 803.000 m3.
DAMPAK VARIABILITAS IKLIM MUSIMAN PADA PRODUKSI PADI SAWAH TADAH HUJAN DI PULAU LOMBOK
 (IMPACT OF INTERANNUAL CLIMATE VARIABILITY ON RAINFED PADDY PRODUCTION IN LOMBOK ISLAND)
Authors: Yasin I. , Ma'shum M.
Published: October 2018

Variability of inter-anuual rainfall has great impact on agricultural production. The inter-annual rainfall variability mainly causes cropping and harvest failure in rainfed land due to drought and flood. Although the onset of season is usully known, the characteristic of in coming rainfall is usually not predictable. Thus the understanding of the cause of rainfall variability may lead to establishment of new system to forecast seasonal rainfall characteristics. The aims of this research are to study water availibity for dry direct seeding rice by considering water balance in southern Lombok and understanding the relationship between ENSO phenomena with rain event in Lombok as well using SOI for predicting seasonal rainfall events. The results of this research showed that average rainfall in southern Lombok is 1450 mm with 950 mm the lowest and 2460 the highest. Southern Lombok has three water surplus months (with rainfall >200 mm), and 5 to 6 water deficit months (with less than 100 mm rainfall).. Inter annual rainfall variation is closely correlated to ENSO phenomena where the rainfall tend to be obove normal in La Niña years and below normal in El Niño years. The short term wet months and wide range of rainfall varibility lead to the need to establishment of water storage system and the application of water and cropping management which suitable to rainfall characteristics and local environmental conditions. The use of ENSO and SOI value to forecast seasonal rain events may be suitable and may reduce the risks of cropping system in rainfed agricultural land.
