Authors: Mulyadi Mulyadi
Published: January 2019

Juwana sub-watershed is a downstream region of the watershed Jragung Tuntang Serang Lusi and Juwana (Jratunseluna). Upstream watershed conservation and the middle of the forest or shrub which is cultivated to vegetable farm will accelerate the degradation of water resources and aggravate the residues of fertilizer and pesticide pollution into the watershed downstream. Soil (sediment) carried by surface runoff is also a major agent of the carrier pollutants in the runoff. Identification of heavy metal content of Pb in soil and grain in Sub-watershed wetland Juwana was conducted in 2009 by survey method. The research objective was to get the data and distribution of heavy metals Pb at sub-watershed wetland Juwana. Surveys and soil sampling grain was approached along Sub-watershed, land forms and sources of contaminants, thus representing samples taken at certain areas were considered homogeneous. Determining the location of the sample in this study will be used as the basis of information in making the map.. The results showed that the metal content of Pb in soils ranged from 0.23 to 2.89 ppm, and Pb in the grain ranged from 0.23 to 1.23 ppm, below the threshold determined value by WHO (2 ppm).

APPLICATION OF BREAKDOWN MECHANICS FOR PREDICTING THE RESOURCE OF AXIAL RADIAL HYDROTURBINS
Authors: Georgievskaia E. V.
Published: January 2019

To plan for timely reconstruction, modernization, repairs or replacement of equipment it is important to reliably predict the instant of its transition to the limiting state that determines the lifetime. Currently, there are no regulatory methods for assessing the lifetime of hydraulic turbines at the operation stage. The approach presented in this paper uses the fracture mechanics methods to build a long-term individual forecast of the dangerous development defects in the main elements of hydraulic turbines taking into account design, technological and operational features. The forecast is based on three-dimensional mathematical models that describe the change in the technical condition of the equipment during time under actual operation. The ANSYS software is used for calculations. Models take into account the size and position of detected or possible defects. Crack growth is determined by the combination of low- and high-frequency loads. The critical length of the crack corresponds to the instant of change of the crack development mechanism, when the failure risk increases sharply. Proposed approach can significantly reduce the possibility of unplanned or emergency shutdown of the hydraulic unit due to its destruction during the overhaul period.

Published: January 2019

Here, NiMn2O4 and NiZn0.2Mn1.8O4 nanocrystalline ceramic powders are fabricated, characterized, and compared for thermistor applications. Solution route was used to synthesize the materials. The NiMn2O4 is a spinel single crystal material with the average crystallite size 26.82 nm and a particle size less than 1 μm and has uniform morphology. The EDS results confirmed the composition of NiMn2O4 that consisted of Ni, Mn, and O2 only. The average crystallite size of NiZn0.2Mn1.8O4 is 37.48 nm and the particle size is less than 0.5 μm. There has been observed some agglomeration formation due to high calcination temperature. The β-value of NiMn2O4 is larger than NiZn0.2Mn1.8O4, hence thermistors constructed from NiMn2O4 are more stable and applicable as NTCR thermistor powder.

The epistemic and pragmatic value of non-action: a predictive coding perspective on meditation
Authors: Lutz Antoine , Mattout Jérémie , Pagnoni Giuseppe
Published: January 2019

The surge of interest about mindfulness meditation is associated with a growing empirical evidence about its impact on the mind and body. Yet, despite promising phenomenological or psychological models of mindfulness, a general mechanistic understanding of meditation steeped in neuroscience is still lacking. In parallel, predictive processing approaches to the mind are rapidly developing in the cognitivesciences with an impressive explanatory power: processes apparently as diverse as perception, action, attention and learning, can be seen as unfolding and being coherently orchestrated according to the single general mandate of free-energy minimization. Here we briefly explore the possibility to supplement previous phenomenological models of focused attention meditation by formulating them in terms of active inference. We first argue that this perspective can account for how paying voluntary attention to the body in meditation helps settling the mind by downweighting habitual and automatic trajectories of (pre)motor and autonomic reactions, as well as the pull of distracting spontaneous thought at the same time. Secondly, we discuss a possible relationship between phenomenological notions such as opacity and de-reification, and the deployment of precision-weighting via the voluntary allocation of attention. We propose the adoption of this theoretical framework as a promising strategy for contemplative research. Explicit computational simulations and comparisons with experimental and phenomenological data will be critical to fully develop this approach.
Federalism: Challenges and Opportunities in Nepal
Authors: Gyawali Gokarna P.
Published: January 2019

It is assumed that the main aspect of the Constitution of Nepal promulgated on September 20, 2015 is the transfer of power from central/federal to the provincial and local government. However, the devolution process has not been satisfactorily experienced as had been expected when it was promulgated by the overwhelming majority of the then Constituent Assembly. One of the reasons for this slow progress might be some confusion and/ or problem in matters of power sharing between different levels of governments. So, the primary objective of the researcher is to review the power sharing modality existing in the new constitution on different sectors and areas of the state machinery. This paper focuses on the federal structure, demography, power sharing between the provincial and local level, opportunities and challenges of federalism in Nepal. It argues that the restructuring initiatives have not been successful in minimizing the political, social, economic, regional and ethnic inequalities that were inherent in the previous political systems for nearly 240 years of a unitary system of governance in Nepal. This paper also explores the implications of Nepal‘s new Federal Constitution for local governance, fiscal policies, cultural identity and other related issues.
“Take My Film and Let It Be”: Critics and Consecration in Faith-Based Cinema
Authors: Moore Rick Clifton
Published: January 2019

This study represents an attempt to better understand how religion fits into the discourse between filmmakers and critics who review their work. The author uses the thought of French sociologist Pierre Bourdieu—specifically, his notions of cultural capital and consecration—to analyze mainstream reviewers’ responses to the motion pictures of Alex and Stephen Kendrick, two brothers who have endeavoured to make mainstream films that “communicate the gospel without compromise.” In analyzing reviews of the Kendricks’ five “faith-based” films, a consistent pattern of comments from the reviewers is evident, a pattern that expresses negativity toward the brothers’ aesthetic, social, and theological choices. Also apparent, though, is an ongoing conversation in which the filmmakers seem to recognize the importance of listening to reviewers, even if the filmmakers have not toned down their message. Reviewer comments for War Room, a film whose budget and box office success have pushed it into the mainstream in spite of its very religious content, show that the filmmakers not only appear aware of the concerns expressed by critics but also persist in their attachment to religious filmic content that may not appeal to secular critics who, in Bourdieu’s terms, have a high level of “cultural capital.” With Bourdieu’s work in mind, the study suggests that many of the disagreements between the filmmakers and reviewers have as much to do with religion, class, and taste as they do aesthetics.
Zombies! “They’re Us!”
Authors: Crooke James R.
Published: January 2019

This article is a “subversive-fulfilment” shaped, theological cultural analysis of George A. Romero’s zombie and its progeny. First, it demonstrates that these memetic artefacts intentionally and unintentionally transmit a critique of human nature through metaphor, cinematic devices, and by stimulating and exposing an apocalyptic fantasy. Then, it brings Christian theology into conversation with the worldview of these artefacts and apocalypticism, construing them using Christian categories. It finds that the Christian worldview construes the artefacts as a product of common “grace” and general revelation and of distorting the truth, particularly with respect to the cause of human aberration and the genre’s asoteriology; thus, the Christian worldview interacts in an affirming, confronting, and fulfilling manner. It construes the apocalyptic fantasy as a concurrent desire to realize an idolatrous autonomy and to escape its consequences. Therefore, it construes indulgence in apocalyptic fantasy as an act of false worship if these yearnings grasp apocalypse as pseudo-salvation.
Day of the Woman: Judges 4–5 as Slasher and Rape Revenge Narrative
Authors: Graybill Rhiannon
Published: January 2019

In Judges 4 and 5, Jael viciously murders the Canaanite general Sisera with a tent peg to the head. This article approaches the text through horror, with particular reference to the slasher film and the rape-revenge film. Drawing on Carol Clover’s landmark Men, Women, and Chain Saws: Gender in the Horror Film, I argue that Jael should be read as a “Final Girl” who triumphs over the villainous Sisera. The article further suggests that because of the strong suggestion of sexual violence and Sisera as rapist, Judges 4 and 5 also invokes the genre of the rape-revenge film. Jael thus becomes the avenging female survivor. These parallels to horror illuminate the complex intersections of gender, ethnicity, and audience identification.
What Is Experience of God? A Hegelian Approach
Authors: Walsh, sj Terrance
Published: January 2019

[Figure: see text]

I will consider the problem of the experience of God in light of the fact that God is not present to consciousness as a phenomenal object. I will present Hegel’s conception of experience in The Phenomenology of Spirit (1807) as a valuable attempt to overcome the restrictions placed upon religious experience by Kant’s definition of experience as “empirical knowledge.” My counterintuitive thesis is that a certain way of thinking about the concept of God constitutes experience of God. Experience of the concept of God has the same status as any other experience of knowing. The concept can be thought and evaluated, and, above all, it can be true—that is, true to itself, to its essence, as a concept.

Published: January 2019

Titanium and its alloys are considered interesting materials for endosseous implants. However, they still present drawbacks related to their in-vivo behavior that can be overcome by coatings, such as apatite. This work focuses on the deposition of apatite coatings on commercially pure titanium (grade II) substrates previously pre-calcified. The influence of the temperature used in the thermal treatment on the microstructure and tribo-mechanical surface properties was analyzed. The coatings were structurally and chemically characterized and their tribo-mechanical behavior was evaluated. The nano-apatite coatings were only formed on surfaces with successive treatments in NaOH and CaCl2 solutions. In addition, scratch tests showed that after the heat treatment the nano-apatite coatings had high bond strength to the substrate.

Re/Making Immigration Policy through Practice
Authors: Dennler Kathryn Tomko
Published: January 2019

Refused asylum seekers living in the UK face hostility and legal restrictions
on the basis of immigration status that limit access to statutory support, employment,
and social goods. Working at a non-profit organization that offered an advice service
for refused asylum seekers, I observed how the experiences of refused asylum seekers
are constituted not simply by restrictions within immigration law, but rather by the
ways in which laws are perceived and implemented by a wide range of actors. I argue
that the legal consciousness of social workers hostile to refused asylum seekers plays
an important role in making policy through practice. I show that social workers prioritized
immigration enforcement over other legal obligations, thereby amplifying the
meaning of immigration status and deepening the marginalization of refused asylum
seekers.
Undocumented People (En)Counter Border Policing
Authors: Brennan Denise
Published: January 2019

This article examines undocumented people’s everyday lived experience in the United States where their legal status is criminalized. It asks how they live with constant threat and surveillance. It highlights their strategies of invisibility as well as their generous contributions to their communities. It argues that these acts of “community caretaking” are acts of “hospitality” that demonstrate their “good citizenship.” Every time undocumented people conduct “know your rights” workshops, they model citizenship in action. The article also explores the other side of the daily equation to stay safe and spotlights undocumented people’s encounters with law enforcement agents. Agents do not act in lockstep, but rather make decisions in split seconds that can change undocumented people’s lives forever. Drawing from ethnographic field research in migrant communities inside the “100-mile border zone” as well as deep in the US interior, the article argues that “border policing” happens far from the border.

Ökonomistische oder politiökonomische Analyse der Ölkrise

Published: January 2019

Die Ölkrise als Ausdruck des Entstehens einer Kapitalistenklasse in den Ölexportländern: mit dieser Aussage will Massarat die von Bassam Tibi und meinen Arbeiten linksbürgerlich unterwanderte Linke in Deutschland wieder auf einen korrekten „politökonomischen" Kurs bringen, dessen Praxisbezug er im Gegensatz zu dem reformistischen, dem Kapital verhafteten Ansatz meiner Arbeit darin sieht, den Arbeitern in den Industrieländern zu erklären, daß sie von dieser neuenKapitalfraktion in den Ölländern ausgebeutet werden (S. 17) (1). Aus der Unterstützung der Perspektiven, die die Ölländer für alle Rohstoffländer c;ier Dritten Welt eröffnet haben, indem sie den Weg zur Vergrößerung der Akkumulationsfonds gezeigt haben und zumindest in einzelnen Fällen die Finanzierungsmittel für neue Umverteilungsmaßnahmen bereitstellen, soll offenbar die westdeutsche Linke herausgehalten werden, und dazu müssen natürlich die Theoretiker einer solchen praktischen Solidarität zwischen den Arbeiterklassen in den Metropolen und den Massen in der Dritten Welt widerlegt werden.
Frauenarbeit im unterentwickelten Kapitalismus

Published: January 2019

Der Subsistenzsektor in Ländern des peripheren Kapitalismus ist weder durch die Modernisierungstheorien, deren Bankrott schon häufig erklärt, deren Anwendung aber doch praktiziert wird, noch durch den Theorieansatz der strukturellen Heterogenität oder des ungleichen Tausches in zureichendem Maß erfaßt worden. Die Ambivalenz der Teilauflösung des Subsistenzsektors einerseits, seiner Aufrechterhaltung andererseits und das Wissen von der kapitalistischen als der dominanten Produktionsweise, sagt wenig über die vorherrschenden Beziehungen und die Produzenten innerhalb dieses Sektors aus. Hinlänglich unbekannt war bis vor kurzem, daß die Frau in vielen Regionen der Dritten Welt die Hauptarbeitskraft im Subsistenzsektor der Landwirtschaft ist.Frauen tragen die Hauptlast der Unterentwicklung in Ländern des peripheren Kapitalismus; sie werden zum Verharren im traditionellen, stagnanten Subsistenzsektor gezwungen, während die Männer eher migrieren und zumindest tendenziell in den kapitalistischen Sektor Eingang finden. Diese von un~ aufgestellten Thesen sollen im Folgenden auf zwei einander ergänzenden Ebenen ausgeführt und belegt werden.

Published: January 2019

As evidenced by our works as well as a number of other researches, sewage sludge is a renewable biological fuel. But the sludge use is quite problematic due to its high humidity and ash content. To reduce the moisture of the initial mass of the sludge, it is recommended to add dry finely dispersed biomass (saw dust, chopped straw). To conduct the research, we selected the long-term storage sludge samples of Bortnichi Activate Sludge Plant of Kiev city and the fresh sludge of the Lvov city purification facilities to produce the granules of 6 mm in diameter. The gaseous conversion of the granules was completed in the two stages according to the «backward heat wave» technology. As it has been established, the coke ash residue accounting for 53–63 % of the output sinters at the temperature of above 700 °С. The research has identified the gaseous conversion parameters, the composition and the combustion heat of the fuel gas. The recommendations pertaining to use of the fuel gas and the coke ash residue have been designed. Accordingly, the research conducted hereunder has discovered the possibility of full and partial gaseous conversion of the sludge granules using the air blast. Bibl. 10, Fig. 5, Tab. 2.

Published: January 2019

In operation of gas turbine plants pollution of aerosol deposits of internal elements of gas-air tracks occurs. This leads to a significant consumption of their power, contributes to increasing energy costs, reducing the operational reliability of installations, through the activation of corrosion and erosion processes. The main requirements for the components of the washing composition are: high washing ability and low corrosion activity. The choice of anticorrosive ingredients for technical detergents provides for the absence of an effect on the effectiveness of the washing composition. One of the important characteristics of technical detergents is its corrosive properties. Exactly this indicator is relevant to the evaluation of the service life of the equipment, so it was the interest to study the dependence of the rate of corrosion on surfactants. The modification of the existing TD and the polyfunctional action ingredients introduced into their composition, which promote the inten-sification of complexing and anticorrosion properties has studied.

THE PECULIARITIES OF WASTE MANAGEMENT IN ZHYTOMYR REGION
Authors: Korzh Z.V.
Published: January 2019

The paper analyses the peculiarities of waste management in Zhytomyr region over the last 5 years. There was a significant decrease (up to 40 %) in the amount of wastes belonging to the hazard Classes I–IV as well as almost 40 times reduction in waste products of the hazard Class III. The largest amount of waste products of the hazard Classes I–IV was formed in Popilnia district, Andrushivka district and Zhytomyr. The smallest amount of these waste products was found in Pulyny, Brusyliv and Baranivka districts. The highest amount of available waste products was registered in Zhytomyr, in Korosten and Ovruch districts respectively. Berdychiv, Malyn and Brusyliv districts were characterized as those ones generating the least amount of waste products. The waste products of mining industry and wastes of organic nature, videlicet wood waste, plant and animal waste account for 28 % of all the wastes generated for the period of 2016. Household wastes, other mineral wastes, and dead rock account for 22 %, 21 % and 16 % respectively. The lack of properly functioning infrastructure (first of all, the system of separate collection) causes annual losses of million tons of valuable resources contained in waste products. The simultaneous need of domestic processing enterprises for such raw materials is solved nowadays by means of purchasing such recyclable materials from other countries. The issue of further implementation of low-waste technologies as well as the improvement of regulatory and legal support in the field of waste management need urgent solving.

Published: January 2019

The radical increase in the density of spraying the flue gas stream in wet Venturi scrubbers allows to significantly increase the efficiency of these dust precipitators to the level of compliance with the European requirements for dust emissions. Such a shift in the operating mode significantly affects the nature of the processes of heat and mass transfer and has feature sthat are important to consider when reconstructing and designing wet gas cleaning plants. The mathematical modeling of the process of flue gas cleaning from fly ash particles in wet Venturi scrubbers in the conditions of excess spraying is performed, the dynamics of the main thermophysical parameters of the heterogeneous flow in a medium with variable moisture content and the influence of the droplet diameter on the efficiency of wet scrubbers are investigated. The problem of changing hydrodynamic resistance of a wet scrubber at different gas flow spraying densities has been studied; the effect of the input fly ash particles distribution on the result of dust cleaning is estimated.

Resumo: Neste artigo apresentamos resultados de uma pesquisa em que buscamos evidenciar como a tecnologia se configura como recurso semiótico no desenvolvimento de uma atividade de modelagem matemática. Para isso, nos fundamentamos na tecnologia como aliada no desenvolvimento de atividades de modelagem e na semiótica, mais precisamente, na abordagem dos recursos que proporcionam a produção de signos – os recursos semióticos. Por meio de uma análise qualitativa de cunho interpretativo de imagens e falas transcritas da atividade de modelagem desenvolvida em cinco momentos por uma turma de nono ano do Ensino Fundamental de uma escola do norte do Paraná, evidenciamos que a tecnologia se configurou como recurso semiótico, em certa medida, para possibilitar aos alunos examinar os princípios da situação-problema, definir o problema a ser investigado, visualizar o fenômeno mais de uma vez, produzir dados, visualizar o comportamento dos dados, proporcionando a obtenção, interpretação e validação de uma solução para o problema.Palavras-chave: Educação Matemática; Modelagem Matemática; Semiótica; Atividade experimental investigativa; Canhão de vórtex. Technologies as a semiotic resource in the development of Mathematical Modeling activitiesAbstract: In this paper we present results of a research in which we seek to show how technology is configured as a semiotic resource in the development of a mathematical modeling activity. We base on technology as an ally in the development of modeling activities and in semiotics, more precisely, in the approach of the resources that provide the production of signs - the semiotic resources. Through a qualitative analysis of images and transcribed speeches of the modeling activity developed in five moments by a ninth grade class of the Elementary School of a school in the north of Paraná, we show that the technology has been configured as a semiotic resource in to investigate the principles of the problem situation, to define the problem to be investigated, to visualize the phenomenon more than once, to produce data, to visualize the behavior of the data, and to obtain, interpret and validate a solution for the problem.Keywords: Mathematics Education; Mathematical Modeling; Semiotic; Experimental investigative activity; Vortex cannon.

Introduction: Road traffic accident (RTA) is a growing public health problem worldwide. It is responsible for greatest number of injuries and fatalities by killing around 1.2 million people each year and injuring 50 million who occupy 30-70% of orthopedic beds in developing countries hospitals. Pedestrians are the most common victims of RTAs.

Objective: To find out the epidemiological factors and pattern of road traffic injury among pedestrians admitted at selected tertiary level referral hospitals in Dhaka City for getting necessary treatment.

Materials and Methods: This descriptive type of cross sectional study was done during December 2015 to June 2016 at four tertiary level referral hospitals in Dhaka. A total of 197 pedestrian patients were selected by purposive and convenient method of sampling. The primary data was collected from the patients after their discharge from hospital by face to face Exit interview using a pre tested semistructured questionnaire.

Results: Among 197 pedestrian victims interviewed; 129(65.48%) were male and 68(34.52%) female. Maximum accidents took place on city main roads 93(47.21%), followed by internal roads 93(47.21%), maximum accidents occurred at day time 87(44.16%), followed by evening 49(24.87%). Regarding vehicles, highest number of accidents were caused by buses 63(31.97%), followed by mini bus 42(21.32%). Highest incidence of injuries was observed among the age group 21 to 30 yrs 81(41.12%), 168( 85.27%) reported that they had been knocked down by the vehicles while crossing the roads (hit and run injury), 24(12.18%) were injured by motor cycles moving at a speed illegally on the footpath, 56(28.42%) people fall on ground due to faulty roads and potholes, open manhole cover followed by vehicle’s accident. Majority of victims 136(69.03%) were from earning group below 15,000 taka per month, most of the victims 155(78.68%) never used foot over bridge,168(85.27%) person faced difficulty while walking through footpath due to piling of construction materials, selling items of neighboring shops etc, 127(64.47)% were using mobile phone while crossing the road or walking through it. All the research samples had multiple abrasion and bruise all over the body, 164(83.25%) had lacerations in different body area, 85(43.14%)%) had fracture of upper limb bones, 69(35.03%)had fracture of lower limb bones .

Conclusion: The incidence and severity of injury of road accident can be prevented by motivation of public, strict application of traffic rules and proper training of drivers. More scientific research on road traffic injury are needed in future.

Introduction: Study in Medical College can act as a contributing factor in developing depression in medical students which may have possible negative academic and professional consequences. Study in any medical course is perceived as being inherently stressful across the globe. Studies on psychological problems such as academic stress, anxiety and depression among medical students have seen that these disorders are under diagnosed and under treated. In this background the present study was carried out with an aim to assess the magnitude of depression and its associated factors in medical students in AFMC.

Objective: To find out the prevalence of depressive symptoms and its associated factors among the students of Armed Forces Medical College (AFMC), Dhaka, Bangladesh.

Materials and Methods: This descriptive type of cross sectional study was carried out in AFMC, Dhaka, Bangladesh for a period from February to April 2014. A total of 211 students studying from 1styear to 4th year MBBS participated in the study. Depression was assessed by Goldberg’s General Health Questionnaire (GHQ-28) and Beck Depression Inventory(BDI) scoring was used to find out the level of depression. BDI scoring 0-10 was considered as normal ups and downs, 11-20 as mild depression, 21-30 as moderate depression, 31-40 as severe depression and more than 40 as extreme depression. Additional questions regarding socio demographic variables were also included. Data analysis was done by software SPSS 19 for windows.

Results: A total of 211 students participated in the study. Among them 86(40.8%) students were reported as having mild to moderate depressive symptoms. Depression was very significantly (p<0.001) higher in 1st year 55(83.3%) than 2nd year 25(38.46%), 3rd year 03(5.45%) and 4th year 03(12%) students. Depression was significantly (p<0.05) higher in Non English Medium background 82(38.8%) than English Medium background 04(1.9%).

Conclusion: Depression may be a significant hidden problem for few of the Medical students and mechanisms to identify and help students with mental health problems should be seriously considered. This calls for in-house counseling service and mentorship program at medical colleges for early detection and treatment of these problems that may help in the improvement of academic performance.
