SUBREGIONAL ENTITIES AS ONE OF THE METHODS OF INTERMUNICIPAL COOPERATION IN THE REGION
Authors: Osipov V.M. , Shevchenko D.I.
Published: September 2018

Inter-municipal cooperation in the world can be implemented in different ways, including: in the form of informal cooperation, the signing of a cooperation agreement, the creation of a municipal enterprise, the creation of mono-or multi-purpose inter-municipal cooperation bodies and delegating power to them, the introduction of an integrated territorial structure whose bodies have competence in matters of strategic importance. The reform of the decentralization and voluntary association of communities in Ukraine provides new opportunities and instruments for inter-municipal cooperation. The creation of subregions, including urban agglomerations as one of its types, is an effective form of such interaction in the world. In Ukrainian legislation, there is practically no mention of these terms in the context of inter-municipal cooperation. Regions face the challenge to act effectively in the case of resource lack, poor institutional framework and deformed governance system that impedes the restoration of economic and political stability at all levels. The solution of this complex problem lies in the intensification of inter-municipal cooperation, including at the subregional level. The article deals with subregional entities in context of improving inter-municipal cooperation in the region. The current legislation in the sphere of inter-municipal cooperation and place of agglomerations and subregions in it are considered. Ukrainian experience in creation of subregions and prospects of such entities in Ukraine are shown. The current experience of the formation of subregions in Ukraine can not be determined as positive, although attempts of its creation and development of socio-economic development strategies are regularly carried out and implemented.
PROBLEMS EFFECTIVE FUNCTIONING OF THE SHIPPING COMPANIES
Authors: Poznanska I.V.
Published: September 2018

The operation of shipping companies in today's rapidly changing conditions is associated with a number of complications due to the dependence of operating activities on many external factors. Recent developments and trends in world trade, characterized by uncertainty, a decline in the rate of growth in trade to rates below the growth of the economy as a whole, which requires a revision of the globalization model of development. Such changes can bring both positive effects and uncertainty in trade and shipping, mainly due to global shifts in the structure of transportation, production and consumption, which may reduce the demand for maritime transport services and the volume of sea transport. Recent trends in the shipping industry have weak growth rates, continuing problems of excess tonnage, imbalance between supply and demand. The article questions of compliance pace and marine transportation trends of the global economy and the need for traffic examines external factors, which have a direct or indirect effect on the development of the freight market: partnership in the field of infrastructure quality, changes in trade policy and liberalization, population growth and urbanization, growing cross-border e-commerce trade, circular economy, reduction of global use of fossil fuels. It is determined which of the factors will increase the volume of transportation and conversely, and that are able to change the structure of the world fleet. It is proposed to move on to new methods of forecasting sea trade flows, different from extrapolation of GDP and growth of trade turnover, including fiscal and environmental policies, as well as transport costs and regulatory aspects.

Authors: Cheng Lim Shiang , Aagaard-Hansen Jens , Mustapha Feisul Idzwan , Bjerre-Christensen Ulla
Published: September 2018

Introduction: Studies from many parts of the world have explored factors associated with poor diabetes self-management including Diabetes Self-Management Education (DSME).

Research Methodology: This study was conducted among 162 diabetes patients at primary healthcare clinics in Malaysia using semi-structured exit-interviews to explore their perceptions, attitudes and practices in relation to self-care and encounters with primary health care providers.

Results and Discussion: Generally, the patients had limited knowledge, lack of motivation and encountered difficulties in diabetes self-management. The DSME was inadequate due to limited time allocated for consultations with doctors, language barriers and the lack of interpersonal and communication skills of HCPs.

Conclusion: In view of the positive effects of quality DSME on the health outcomes and quality of life among diabetes patients, it is important for the primary healthcare clinics in Malaysia to strengthen the diabetes services through training in communication of all HCPs, awareness of language difference and task shifting.
EVIDENCE- BASED ACTION PLAN OF REHAB CENTERS FOR PATIENTS WITH LOW BACK PAIN
Authors: M. Cutamora Ulysses
Published: September 2018

Back pain is common and many people experience long term problems. The goals of physical therapy are to decrease back pain, increase function and provide health education. Low back pain (LBP) is pain, muscle tension, or stiffness localized below the costal margin and above the inferior gluteal folds, with or without sciatica, and is defined as chronic when it persists for 12 weeks or more. The study objective is to enhance the compliance of Patients to Rehabilitation Regimen to achieve better prognosis and treatment outcomes. The respondents of the study were low back pain patients from three (3) different rehabilitation centers, Rehabilitation Medicine of Cebu Velez General Hospital, Rehab Solutions Incorporated in Perpetual Succor Hospital and Rehab Medics of Chong Hua Hospital. To answer the mean characteristics of the respondents, descriptive statistical procedures were utilized. To determine the differentiating factors, discriminant analysis was used while logistic regression was utilized to determine the predictors of therapy outcomes. This study utilized a quantitative descriptive research design which enabled the researcher to determine if there exists a relationship between the therapy outcomes as the dependent variable to the demographic, employment and clinical variables identified in the study. It can therefore be concluded that of the twelve (12) variables explored, only four (4) clinical variables are significant predictors of low back pain treatment outcomes. These are (a) compliance to treatment regimen, (b) Co-morbidity, (c) Surgical history and (d) Type of low back pain. The rehabilitation centers would take into consideration the results of the study and that they will find a better way encourage compliance of patients to rehabilitation treatment utilizing the proposed evidence-based action plan. With this development, the problem with regard to compliance and result of rehabilitation treatment will be addressed and will greatly contribute to overall wellness and successful outcome of low back pain treatment. It is therefore imperative that physical therapists should focus on these clinical variables in treating for patients with LBP and recommended that rehabilitation centers should follow the evidence-based action plan.

Klasse und Gewalt
Authors: Lotz Christian
Published: September 2018

In this essay I briefly analyze why the concept of class has disappeared in recent social philosophy, such as in the philosophies of Badiou, Negri/Hardt, and Honneth. I argue that a change in the foundations of their social ontologies has led to the dismissal of the concept of class and, in addition, I argue that these changes are unwarranted, since they lead to a loss of a critical concept of society. Then, in a second part, I argue that the concept of class deserves a systematic status within a theory of capitalist sociality, especially since the concept of class can be traced back genetically to violent social relations that are derived from the capitalist social order.

Published: September 2018

Mainstream economists and macroeconomic research institutes are interpreting the economic crisis of 2008 mainly as a result of turbulances in the financial sphere of the economy. US National Accounts data indicate that Every recession in the USA from 1950 till 2010 – including the recession of 2008 – was preceded by a similar pattern in the development of the real economy. In addition the paper argues that the phenomenon of financialisation and the neoliberal regime of accumulation has its ultimate reasons in the development of the real economy.
Die Proteste der Refugees
Authors: Plöger Andrea
Published: September 2018

For the first time refugee and migrant protests have developed into a social movement in Germany. The refugee movement is also part of a transnational network, which has developed during and in accordance with the current protest cycle started by the Arab Spring. Broad mobilizations spring from this movement but have not yet let to substantial changes due to the post-crisis restructuring of the EU with „margin“ and „central“ countries. While the neoliberal restructuring in the global south is causing the „production of migration“ to speed up, also the „99 percent“ in the global north are concerned. The migrant and refugee movement is challenging the base of this neoliberal agenda as it aims at the functioning of deterrence, control and deprivation in the global south and north.

Fabrication of a Flexible Current Collector for Lithium Ion Batteries by Inkjet Printing
Authors: Gu Yuan , Federici John
Published: September 2018

A novel chemical process has been developed to formulate injectable nickel ink for conductive film. This chemical method has the ability to remove the oxidation on nickel nano-particle surfaces during ink fabrication; the nickel ions, which are produced during chemical etching, will be reduced and bridged among original nano-nickel particles in the following thermal sintering process at 350 °C. X-ray diffraction results exhibit that the final nickel film has no significant composition change by this chemical method and that oxidation has been effectively removed. Scanning electron microscopy images show that this chemical process reduces nickel oxides into nickel and that the reduced nickel sticks on the original nickel particle surface acting as a “bridge” connecting each particle. So solid diffusion can be triggered easily among bridged nickel particles and sintered at relatively low temperatures. The resistivity of printed film is to 5 × 10 − 6 Ω ∙m which is 71-times that of bulk nickel. The fabricated conductive nickel thin film has been applied on lithium ion batteries as a current collector for cathode and anode and shows good corrosion resistance and stability.
The Influence of Dosing Method and Material Characteristics of Superabsorbent Polymers (SAP) on the Effectiveness of the Concrete Internal Curing
Authors: Woyciechowski Piotr P. , Kalinowski Maciej
Published: September 2018

This paper examines the influence of dosing method and material characteristic of superabsorbent polymers (SAP) used for internal curing, on the selected concrete properties. A new method of introducing SAP into the concrete mix and its impact on the shrinkage and compressive strength of concrete was studied. It was shown that the method of dosing SAP to the concrete mix and the differences in the properties of the tested SAPs have a significant impact on the course of changes of selected properties of the tested concrete composites. In order to compare tested series with each other and with other published results on the subject, a new method of including SAP mass content in the concrete mix, as a percentage of absorbed mixing water, was presented. The effectiveness of internal curing using different types of SAP under different dosing methods was presented as a percentage difference in tested concrete properties between modified series and reference series.

Published: September 2018

Aluminum alloy 5083 is widely used in the fabrication of marine vessels. This paper presents the difference in mechanical properties and microstructure between natural-cooling and water-cooling after flame straightening. Under the synchronous water-cooling process, the peak temperature of the heating center was unchanged, but the peak temperatures of the other areas decreased obviously and the cooling rate increased substantially. The microhardness of the rectified area was lower than that of the base metal. The average microhardness decreased about 4.4 HV when using synchronous water-cooling, whereas the average microhardness of the specimen without using water-cooling was 11.6 HV lower than the base metal. Tensile test results show that the yield strength and the ultimate strength of synchronous water-cooling specimen increased 9.16 MPa and 1.64 MPa on average, but the elongation rate decreased compared with the specimen only under flame straightening. The results of metallographic tests show that the grain growth tendency and precipitation phase size and quantity reduced after using synchronous water-cooling.
Worldview Analysis in a Comparative Context: Fishing for Data in Muddy Waters
Authors: Johnston Lucas F.
Published: September 2018

Drawing on the five-fold revision of the concept of “worldview” offered by the issue editors, I investigate whether some nonreligious modes of cultural production might be profitably investigated using such a typology. In my comparative study of religious and secular sustainability-oriented social movements I offered skeletal definitions of the categories “religion” and “sustainability,” and suggested ways in which public deployments of such terms might offer fertile ground for collaboration between individuals and groups with different value sets. In more recent work among particular rock music and festival scenes, I have found it necessary to offer a dramatically different understanding of the category “religion.” In a sort of thought experiment, I imagine whether the revised concept of “worldview” might be applicable, and indeed whether it offers some advantage over the category “religion.” My conclusions are that in general, in some cases the category of worldview may have some advantages, but it may also gloss over or ignore important cultural contestations over terms such as religion, and at best underplay important affective activators of belonging and identity. The notion of “ways of life,” or “lifeways” may offer a term which avoids some ethnocentric impositions, but would require greater elaboration to be broadly useful to ethnographers.
Coworking, the Sharing Economy, and the City: Which Role for the ‘Coworking Entrepreneur’?
Authors: Durante Giacomo , Turvani Margherita
Published: September 2018

Sharing economy platforms enabled by information and communication technologies (ICTs) are facilitating the diffusion of collaborative workplaces. Coworking spaces are emerging as a distinctive phenomenon in this context, not only fostering knowledge transfer and facilitating innovation, but also affecting the urban and socio-economic fabric contributing to urban regeneration processes at both the local scale and the city scale. Although the positive impacts of coworking on the urban environment are documented, there is still little or no evidence of the economic viability of coworking businesses, and a “coworking bubble” has been evoked. Given the lack of data, a national survey was set up of Italian coworking businesses, aimed at assessing the relevance of internal organizational factors (size, occupancy, profitability, services provided) for the sustainability of coworking businesses. By presenting the results of the survey, we argue that the sustainability and viability of the coworking model is highly dependent on internal factors, strictly related to the entrepreneurial action of coworking managers.
On the molecular and morphological evolution of continental and insular Cryptorchestia species, with an additional description of C. garbinii (Talitridae)

Published: September 2018

Semi-terrestrial talitrid amphipods of the genus Cryptorchestia (sensu Lowry and Fanini 2013) associated with freshwater-soaked leaf litter were known to occur in inland lakes of Turkey and at the shores of the Black Sea. Before 2013 they had been reported as Orchestiacavimana and later as Cryptorchestiacavimana. In our phylogenetic tree, inferred from a mitochondrial and nuclear gene dataset (cytochrome oxidase I (COI), and histone H3 (H3), respectively), we show that these Turkish populations belong to Cryptochestiagarbinii, a common and widespread continental species, which is closely related to C.cavimana (endemic to Cyprus) and C.ruffoi (endemic to Rhodes). For the Turkish and European populations of C.garbinii, we found low levels of both genetic differentiation and morphological variation, and an age-related size variability (increasing at each moult) of the small lobe in the male gnathopod I merus, the main taxonomically diagnostic character for Cryptorchestia. A mainland (C.garbinii) versus insular isolation and in situ speciation (C.cavimana, and C.ruffoi) in the two east Mediterranean islands of Cyprus and Rhodes is discussed in relation to terrestrial Cryptorchestia species endemic to North East Atlantic volcanic islands (Azores, Canary Islands, and Madeira). The incorporation of five Mediterranean and Atlantic Orchestia species in the Bayesian analysis of the two genes (COI, and H3) indicated that both genera Orchestia and Cryptorchestia are not monophyletic.

Published: September 2018

A vulnerabilidade é um indicador da iniquidade e da desigualdade social e detecta as fragilidades do indivíduo e sua capacidade de enfrentamento dos problemas e/ou agravos de saúde. Compreender os fatores que influenciam no envolvimento e manutenção do uso de drogas na gestação pode contribuir para o diagnóstico precoce de vulnerabilidade e no planejamento de intervenções que auxiliem na evolução de uma gestação saudável. O objetivo foi examinar os planos analíticos de vulnerabilidade para compreensão do uso de drogas na gravidez. Trata-se de um estudo retrospectivo, descritivo e exploratório, utilizando como referencial teórico contextos de vulnerabilidade nos planos analíticos individual, social e programático. Um roteiro de entrevista semiestruturado composto por quatro eixos temáticos e analisado de acordo com o referencial teórico de vulnerabilidade foi utilizado. As 12 mulheres tinham entre 17 e 33 anos e utilizavam múltiplas drogas desde a adolescência. O tabaco e álcool foram as drogas de iniciação e o crack a mais frequente na gravidez. As mulheres foram consideradas vulneráveis nos três planos, uma vez que elas viviam em um ambiente de risco, caracterizado por famílias, que mantêm cultura aditiva, conflitos com a justiça, violência intrafamiliar, vivências de situações sociais de crime e abuso e ausência de vínculo com serviços de saúde.

Intensification of Open Mining Operations with a Small Distance of Transportation of Rock Mass
Authors: Cheban Anton Yurievich , Khrunina Natalia Petrovna
Published: September 2018

Sometimes in open mining, it is economically expedient to extract and transport rock mass with the help of wheel tractors-scrapers. To improve the hopper filling with the rock mass operating with clay or loosened rocks, it is advisable to use scrapers equipped with loading intensifiers in the form of a raking wall located inside the hopper. The article presents the experimental filling study results of wheel tractor-scraper hopper models of different capacities with a standard and increased hopper length at the presence or absence of a raking wall. The investigations were carried out on an experimental rock removal bench equipped with a strain gauge measuring system to record forces that arise during the hopper model filling with rock mass. Data are given on the rock mass removal for various filling methods, as well as for the resistance values for the piling wall movement and the energy capacity of the hopper filling process for operating with sandy loam, loam, clay, and limestone crushed stone. There were realized the calculations of the operational productivity and the specific cost of works, depending on the rock mass transportation distance with elongated hopper scrapers equipped with a scraper wall, scrapers with standard hoppers and scrapers operating with a pusher bulldozer set. The rational application areas for each of the machines were revealed.

Authors: Ohenhen Ikponwosa , Ogiriki Shadrach Olise , Imuetiyan Igbinohodua , Ezeja Okechukwu
Published: September 2018

Drilling mud is an essential component in well drilling processes. The high temperature at the bottom of wells tend to reduce the mud viscosity and density, thereby affects the ability of the mud to perform its useful purpose in the drilling operation. Additives are usually added to the mud to enhance its properties to meet desired specifications. Carboxylmethyl Cellulose (CMC) is added to increase the mud viscosity and barite is added to increase the mud density. This work presents an investigation on possible substitutes for these additives. Locally sourced materials, Cassava (Manihot manifera) and Water yam (Dioscoria alata) were compared to barite and CMC. The properties measured are the rheological properties of the mud slurry which are plastic viscosity, apparent viscosity, yield point and gel strength, mud density, filtration properties at varying high temperatures (120 – 150 oF), and hydrogen-ion (pH value). The results revealed that both local additives can serve as weighting materials as they increased mud density more than barite. Filtration properties of water yam were better than CMC and Fresh mud both at room temperature and high temperatures. The results futher indicated that water yam and cassava additives were non acidic, therefore are less corrosive as compared to CMC which was acidic. It was concluded that cassava and water yam are potential substitutes of CMC.

Markov’s theorem classifies the worst irrational numbers with respect to rational approximation and the indefinite binary quadratic forms whose values for integer arguments stay farthest away from zero. The main purpose of this paper is to present a new proof of Markov’s theorem using hyperbolic geometry. The main ingredients are a dictionary to translate between hyperbolic geometry and algebra/number theory, and some very basic tools borrowed from modern geometric Teichmüller theory. Simple closed geodesics and ideal triangulations of the modular torus play an important role, and so do the problems: How far can a straight line crossing a triangle stay away from the vertices? How far can it stay away from all vertices of the tessellation generated by this triangle? Definite binary quadratic forms are briey discussed in the last section.

We establish a natural and geometric 1-1 correspondence between projective toric varieties of dimension

n

and horofunction compactifications of

\mathbb R^n

with respect to rational polyhedral norms. For this purpose, we explain a topological model of toric varieties. Consequently, toric varieties in algebraic geometry, normed spaces in convex analysis, and horofunction compactifications in metric geometry are directly and explicitly related.

On a polarized compact symplectic manifold endowed with an action of a compact Lie group, in analogy with geometric invariant theory, one can define the space of invariant functions of degree

k

. A central statement in symplectic geometry, the quantization commutes with reduction hypothesis, is equivalent to saying that the dimension of these invariant functions depends polynomially on

k

. This statement was proved by Meinrenken and Sjamaar under positivity conditions. In this paper, we give a new proof of this polynomiality property based on a study of the Atiyah–Bott fixed point formula from the point of view of the theory of partition functions, and a technique for localizing positivity.

Introducción: Los sitios contaminados a causa de la actividad minera representan un riesgo para la salud humana.Objetivo: Determinar la concentración de minerales tóxicos (Hg, Pb, Cd y As) en dos pasivos ambientales (PA) en Noria de Ángeles, Zacatecas.Materiales y métodos: Se tomaron muestras de suelo de dos PA y de un sitio de referencia con base en la NMX-AA-132-SCFI-2006; además, se muestrearon un manantial y cuerpos de agua adyacentes o sobre los PA, conforme a la NOM-230-SSA1-2002. Los elementos tóxicos en el suelo y agua se analizaron de acuerdo con la NOM-147-SEMARNAT/SSA1-2004 y NOM-127-SSA1-1994, respectivamente. Las concentraciones de elementos en el suelo se sometieron a análisis de varianza y comparación de medias Tukey (P < 0.05). Resultados y discusión: La concentración de Hg fue mayor (P < 0.05) en los PA respecto al sitio de referencia, pero no rebasó los límites máximos permisibles (LMP) establecidos por las normas. El Cd y As en el suelo de los PA y sitio de referencia rebasaron el LMP, y el Pb solo en los PA. Se deduce que el As tiene origen geológico principalmente, ya que su contenido en el sitio de referencia fue superior al PA reciente. En los cuerpos de agua, las concentraciones de Pb, Hg, Cd y As fueron muy superiores a los LMP.Conclusión: El Pb, Cd y As en los PA, y el Pb, Cd, Hg y As en los cuerpos de agua representan un riesgo para la salud de la población de Noria de Ángeles, Zacatecas.

Introducción: Los manglares son los mayores sumideros de carbono y contribuyen a mitigar los efectos del cambio climático global.Objetivo: Estimar la biomasa aérea (BA) del estero El Sargento y de la Bahía del Tóbari, para comparar los almacenes de carbono entre ambos lugares.Materiales y métodos: Las mediciones se realizaron en mayo de 2014 a noviembre de 2015. Las especies se identificaron, y el diámetro de árboles, altura y cobertura del dosel se midieron en 16 parcelas de 10 x 10 m. La BA se estimó con ecuaciones alométricas y se relacionó con el contenido de carbono mediante el factor 0.5. Las diferencias estadísticamente significativas entre los contenidos de carbono de ambos sitios de estudio se detectaron con la prueba t para muestras independientes.Resultados y discusión: La BA en el estero El Sargento se estimó entre 108.1 y 316.78 Mg∙ha-1 con predominancia de Laguncularia racemosa (L.) Gaertn (60 %); en Bahía del Tóbari, la BA varió entre 72.12 y 130 Mg∙ha-1, prevaleciendo Avicennia germinans (L.) L (83.4 %). En los dos sitios se encontró Rhizophora mangle L. de manera marginal. El almacén total de carbono fue mayor en El Sargento (con un rango de 54.1 a 158.4 Mg C∙ha-1) que en Bahía del Tóbari (36.1 a 65.5 Mg C∙ha-1); la diferencia fue estadísticamente significativa (F = 0.01; P = 0.02).Conclusión: La diferencia en las reservas de carbono de los lugares de estudio se relaciona con el buen desarrollo y diversidad de especies de un medio ambiente prístino (El Sargento), en comparación con otro severamente impactado (Bahía del Tóbari).

Abstract. Sperm-mediated gene transfer (SMGT) has been considered as an innovative device for transgenesis on a mass scale by taking advantage of live spermatozoa to transfer exogenous DNA. However, the fertilizing ability of transfected sperm cells and the poor reproducibility of this method are still matters of controversy. Hence, the current study was conducted to evaluate transfecting the enhanced green fluorescent protein (EGFP) as the source of exogenous DNA into bovine spermatozoa using a high-performance polymer reagent as well as assessing the fertilizing capacity of transfected sperm cells by in vitro fertilization (IVF). In the first experiment, three different concentrations of rhodamine-labeled DNA and high-performance polymer transfection reagent, X-tremeGENE HP, were used to transfect bovine spermatozoa. In the second experiment, IVF and fluorescence microscopy methods were utilized to assess the fertilizing capacity of sperm cells carrying exogenous DNA when X-tremeGENE HP was used either alone or with dimethyl sulfoxide (DMSO) treatment. Findings revealed that at 1 µL X-tremeGENE HP and 1 µg of DNA concentration, approximately one-third of total spermatozoa were transfected. However, following IVF and fluorescence microscopy, no EGFP expression was detected in zygotes and morula-stage embryos. Results of this study showed that, although X-tremeGENE HP could transfer EGFP to bovine spermatozoa, transfected sperm cells were unable to transfer foreign DNA to matured bovine oocytes. Under our experimental conditions, we hypothesized that the absence of the EGFP fluorescence signal in embryos could be due to the detrimental effects of transfection treatments on sperm cells' fertility performance as well as incompetency of IVF to produce transgenic embryos using transfected sperm cells.

Abstract. Weekly vertical profiles of ammonia (NH3) were measured at 16 heights on the Beijing 325 m meteorological tower for one year from March 2016 to March 2017. Measured average NH3 concentrations at all heights exceeded 5 µg m−3 with an overall average (±1σ) tower concentration of 13.3±4.8 µg m−3. The highest NH3 concentrations along the vertical profiles mostly occurred at 32–63 m, decreasing both towards the surface and at higher altitudes. Significant decreases in NH3 concentrations were only found at the top two heights (280 and 320 m). These results suggest an ammonia rich atmosphere during all seasons in urban Beijing, from the ground to at least 320 m. Highest concentrations were observed in summer, associated with high temperature. The average NH3 concentration across the profile from high to low was observed in summer (18.2 µg m−3), spring (13.4 µg m−3), autumn (12.1 µg m−3), and winter (8.3 µg m−3). Significant vertical variation of NH3 concentration was only found in summer. Transport analyses suggest that air masses arriving from intensive agricultural regions to the south contribute high NH3 concentrations in Beijing. Local sources such as traffic emissions also appear to be important contributors to atmospheric NH3 in this urban environment.
