Movilidad humana. El fenómeno migratorio en Puebla bajo la perspectiva de la Iglesia católica
Authors: Sánchez Gavi José Luis
Published: October 2018

El presente trabajo describe y analiza la incidencia que la Iglesia católica tiene en el tema migratorio en el estado de Puebla. En la entidad, la institución eclesial ha manifestado su interés y preocupación por el fenómeno migratorio; además, ha desarrollado un trabajo, especialmente en el terreno humanitario, y ha buscado alternativas para las familias que se quedan en las comunidades. Puebla ha pasado a ocupar el quinto lugar nacional como entidad expulsora de migrantes. Cobra importancia que por su territorio transite cada vez un mayor número de transmigrantes, en un intento por modificar sus rutas a fin de atenuar la inseguridad que se ha apoderado de ellas. Migrantes oriundos, de retorno y transmigrantes son parte de la realidad social, económica, cultural, religiosa y hasta política en el escenario poblano. Requieren abordaje tanto en el plano de la investigación académica, como en el de las políticas públicas. La Iglesia, como otras organizaciones no gubernamentales, se ha sumado a las tareas de apoyo, protección y denuncia, en medio de un panorama de incertidumbre, inseguridad y violencia que aqueja a los migrantes. Bajo su particular perspectiva ideológica y religiosa, busca influir en la definición de las políticas migratorias, y mantener una forma de legitimidad en la sociedad.

Organizational, technical and other aspects have been considered. The principles of the development of the information support have been proposed and the organizational and methodic measurements of its improvement have been marked out, such as one-shot and safe input of the information; personified responsibility for the operational efficiency and accuracy; accessibility and gratuitousness of the information transmission, except the information with access, limited by the low; the design and maintenance of the base list-registers (basic systems).
Bacterial mats of the oxide ores in the world ocean
Authors: Avdonin V. V. , Zhegallo E. A. , Sergeeva N. E.
Published: October 2018

Bacterial mats, formed by successively accumulating biofilms, are the main constructive component of the oxide ferromanganese ores on the oceanic floor. The coordinated behavior of the bacterial colonies in the biofilms controlled the growth of the stromatolites and onkolites structures. Biofilms of the stromatolite bacterial mats represent the microbial community, with the thread bacteria forming a poiygonal network that determines a piliar structure of the crusts. Bacterial mats in nodules are festoon-shaped. Biofilms in festoons intensely interact with the environment, assimilating petrogenic components and consuming the sedimentary material.
The influence of the atmospheric front on the readings of the gravimeters and seismographs
Authors: Antonov Yu. V.
Published: October 2018

Non-tidal variations of gravity are the residual part of the monitoring of the variations after subtraction from them the lunar-solar gravity variations and the drift of the zero point of the gravimeter. Non-tidal variations have a complex morphology and structure. The sources of the non-tidal variations are the intracrustal processes, flows of the charged particles in space and meteor showers. Meteor showers interacting with the Earth’s atmosphere determine the occurrence, development and movement in the atmosphere of the large-scale eddies - cyclones and anticyclones. The atmospheric fronts are distinguished in isolated cyclones. These fronts can influence the measurements of the gravimeters and seismographs.
PROVENANCE AREA OF PRECAMBRIAN QUARTZITE-SCHIST SEQUENCES OF THE KOKCHETAV MASSIF (NORTH KAZAKHSTAN)
Authors: Kanygina N. A. , Tretyakov A. A. , Degtyarev KE. . , Kovalchuk E. V.
Published: October 2018

The results of a study of quartzite-schist sequences of the Prevendian basement of the Central and Western parts of the Kokchetav massif in the Northern Kazakhstan and ore placer deposits, confined to them, are provided. An accumulation of the both formations took place in the shelf part of the passive margin of the large continental block. Petrological and geochemical characteristics as well as the compositions of the rutile and tourmaline from palaeoplacers indicate that the clastic material came from a one distributive province. The rocks metamorphosed under the moderate and high temperatures, metasedimentary and metabasic complexes had an important role in the structure of the distributive prov-nce with the less significant role of the felsic magmatic rocks.
NEW CHRONOSTRATIC SCHEME OF SOUTH-EASTERN FENNOSCANDIA AND ITS USE IN THE PREPARATION OF SMALL-SCALE GEOLOGICAL MAPS OF THE PRECAMBRIAN REGIONS
Authors: Kulikov V. S. , Kulikova V. V. , Polin A. K.
Published: October 2018

A new chronostratic scheme of South-East (SE) Fennoscandia has been developed, based on the International Stratigraphie Scale, taking into account some elements of the Common Stratigraphic Scale of Russia and the regional stratigraphic scheme of the North-West (NW) of Russian Federation. A rank of Archean and Proterozoic stratons has been determined (including supersystems for Riphean and Archean geonotems), compatable in dutation to the Phanerozoic systems (Mesozoic and Paleozoic ones). An original coloring for the geological maps of the newly allocated systems and their analogues in the Precambrian, as well as the digital indexing of all stratons of the rank of systems instead of the traditional alphabetic one, have been proposed. Based on the extensive geological materials of the Institute of Geology of Karelian Research Centre of the Russian Academy of Sciences, in view of the new approaches and reliable geochronological data, an areal geological map of SE Fennoscandia in scale 1: 750 000 has been created, which includes the territory of Karelia and adjacent areas of the Russian Federation and eastern Finland. The proposed chronostratic scheme can serve as a basis for developing legends of small-scale state geological maps of the new generation, especially in the regions of the Precambrian development.

The «Tectonic codex of Russia», edited recently, has been critically considered. An inability to use it in the learning process has been prooved.
A METHOD OF ESTIMATION THE PARAMETERS OF THE AQUIFERS BASED ON THE DATA OF TESTING FILTRATION WORKS UNDER CONDITIONS OF HYDRAULIC COUPLING
Authors: Malkov A. V. , Pershin I. M. , Pomelyayko I. S.
Published: October 2018

The paper proposes a technique for determining the hydrodynamic parameters under conditions of the hydraulic coupling of the aquifers. A test modeling has shown that the existing methods of determining the flow parameter (Teys, Jacob, Hantush) give significant errors. They can be used only under the assumptions that are made in the derivation of the known calculated dependencies. The accuracy of the determining the overflow parameter has been shown to be largely determined by the ratio of the water loss of the aquifer under study and the adjacent one, which is a source of additional nutrition. For a whole range of tasks, such as income of the poor-quality polluted waters from the donor horizon or studying the dynamics of the mineral water conditioning composition, the processes of overflow can be a determining factor. The proposed technique is free from these shortcomings, but requires a cycle of cluster testing filtration work on all interacting aquifers.

Authors: Petrochenkov D. A.
Published: October 2018

The large crystals of the collection and jewellery quality (including the crystals unique by size) have been found at the Iultin deposit (Eastern Chukotka). The jewellery ones are connected with veined morphological type of the ore bodies and located in the mineralized cavities and muscovite fringes. A black colour of cassiterite is conditioned by large number of the zones of the growth which absorb passing light. Significant by volume colourless and different-coloured fragments can be found in crystals. They can be used for faceting of high quality. The cassiterite of collection and jewellery quality is an important factor of profitability's raising in exploitation of tin deposits.
LONG-LIVED STRUCTURAL ENSEMBLES OF THE EAST EUROPEAN PLATFORM. ARTICLE 1. THE BASEMENT TECTONICS
Authors: Kolodyazhny S. Y.
Published: October 2018

General features of the basement tectonics of the East European platform (EEP) have been considered. The important role of the long-lived Paleoproterozoic tectonic zones has been noted. They were formed due to the cyclic processes of rifting and compression combined with the strike-sleep shearing. They include different structures often superimposed in space: systems of rifts and collisional orogenic belts, transtensional and transpressional zones, ensembles associated with tectonic-plate processes. A special role belongs to the non-linear structures: different scaled rotational structures, concentric and spiral shaped shears, the arcuate orocline belts and horizontal protrusions. Long-lived Proterozoic zones form a giant vortex structure twirled in a clockwise direction, the pole of which is located in the center of the Upper-Volga geodynamic node. The rotational processes of this giant structure can explain many tectonic features of the EEP development.
ECOLOGIC POTENTIAL OF THE ENVIRONMENTAL AND HYDROGEOLOGICAL SYSTEMS IN THE AREA OF KUCHINSKY MUNICIPAL SOLID WASTE LANDFILL (MOSCOW REGION)
Authors: Fisun N. V.
Published: October 2018

The paper describes the interpretation of the terms «ecologic potential» (EP) and «environmental and hydrogeological system», proposed by the author to assess the ability of the hydrogeological system to maintain or restore the properties of its self-organization under the influence of the man-caused stress. The environmental-hydrogeological systems developed within the boundaries of Pekhorskoe deposit of groundwater in the area of landfill «Kuchino», have been considered. The high level of the groundwater pollution of the lower-middle Quaternary aquifer as a system of the type I devoid of aeration zone as a result of storage of municipal solid waste (MSW), has been suggested. The evidence data of the groundwater quality of the aquifer Kasimov as the EGGS of type II has shown the formation of the high ecologic potential, stable for more than 50 years as a result of the processes of destruction in relation to nitrogen compounds, organic substances, petroleum products, anionic surfactants, pathogenic microorganisms, phenols. It is also shown that macro-components have a lower potential, which is provided by the processes of groundwater flow expansion of the the solid waste landfill.
GOLD AND MERCURY IN THE PROCESSES OF ORE FORMATION IN KAMCHATKA
Authors: STEPANOV V. A.
Published: October 2018

The main features of the difference and similarity of the physical and chemical properties of gold and mercury have been given, which  determine their behavior in the natural processes of formation of  deposits of both metals in Kamchatka. It has been shown that the  difference in the properties of gold and mercury led to the  emergence of independent monometallic deposits, differing in  connection with intrusive formations, in depth and temperature of  ore formation. The similarity of the properties of these elements  determined the appearance of mercury minerals on gold ore deposits and gold in mercury deposits, as well as the formation of complex  gold-mercury deposits. Four geological-industrial types of gold- mercury deposits have been distinguished: the Knoxville, the Carlin,  the Kyuchus and the Chemlian ones, which include deposits with  large gold reserves both abroad and in Russia. The identification of  gold deposits, including through the revision of mercury ore  occurrences and deposits of Kamchatka for gold presence, will strengthen the mineral resources base of gold in this region.
John Henry Newman on faith and reason
Authors: Briel Don J.
Published: October 2018

The author explains how, in contrast with the risk “of the twin reduction of faith to a mere emotive principle and reason to a mechanical exercise”, Newman seeks to re-define and widen the concepts of reason and philosophy, so that, free from rationalism, philosophy and reason can again give sense to one’s lived experience. A reason so widened by the “experience of life” and by a living heart will be much more able to welcome a faith which is given to it not as a right, or as syllogism, or as a burden, but as gift of love. Thus, faith is no longer seen as something irrational, distant, accidental, as if it were a simple “private preference”. Instead, it becomes a very reasonable and warm impulse that changes man’s perspective over his existence and his Christian commitment, and transfigures him towards a life of holiness.
Hacia una psicología de la persona.
Authors: Domínguez Prieto Xosé Manuel
Published: October 2018

El presente ensayo trata de comprender la psicología como ciencia desde un fundamento antropológico personalista e integral. Para ello se analiza el objeto formal de la psicología y su objeto material para cada una de las diversas disciplinas psicológicas, mostrando que todos los fenómenos psíquicos son fenómenos que ocurren y se comprenden desde la persona. Se justifica que la psicología necesita a la antropología filosófica como fundamento epistemológico. Además, esto nos permite entender cada fenómeno psíquico en el contexto de la persona en que ocurre, lo que supone una nueva visión del concepto de salud personal.

El corazón y la palabra: claves para una regeneración sapiencial de la formación
Authors: GRANADOS Carlos
Published: October 2018

El artículo pretende responder a las siguientes preguntas: ¿Cómo se hace un hombre sabio? ¿De qué modo la Sabiduría penetra en su corazón y lo va conformando poco a poco con sus manos de artista? ¿Qué dificultades encuentra el hombre de hoy para dejarse conformar por estas manos? Se recuerdan, en primer término, algunas de las dificultades mayores que encuentra el hombre moderno en este camino hacia la sabiduría. La actual coyuntura ha supuesto, ciertamente, la quiebra de una serie de prácticas formativas y de fundamentos esenciales. Pero ha tenido el efecto positivo de obligarnos a replantear las preguntas clave de la educación, a repensarla. Tras describir brevemente algunas de las dificultades, el artículo propone, finalmente, algunos caminos para el replanteamiento.
Asymptotic Farkas lemmas for convex systems
Authors: Nguyen Dinh , Tran Mo Hong
Published: October 2018

In this paper we establish characterizations of the containment of the set {xX: xC,g(x)K}{xX: f (x)0}, where C is a closed convex subset of a locally convex Hausdorff topological vector space, X, K is a closed convex cone in another locally convex Hausdorff topological vector space and g:X Y is a K- convex mapping, in a reverse convex set, define by the proper, lower semicontinuous, convex function. Here, no constraint qualification condition or qualification condition are assumed. The characterizations are often called asymptotic Farkas-type results. The second part of the paper was devoted to variant Asymptotic Farkas-type results where the mapping is a convex mapping with respect to an extended sublinear function. It is also shown that under some closedness conditions, these asymptotic Farkas lemmas go back to non-asymptotic Farkas lemmas or stable Farkas lemmas established recently in the literature. The results can be used to study the optimization

Albumin Infusion Therapy in Critical Patients
Authors: Haque Sheikh Anisul , Kabir Fahmida , Haque Khawaja
Published: October 2018

Human albumin has been the area of interests and research for the last 65 years. A major advance in our understanding of albumin has been achieved as complete gene sequence and the location of mutations of albumin was unfolded. Clinical uses of albumin were first introduced during the Second World War when adequate plasma supply was not possible due to logistical complexities. In the 1950s, this protein was introduced for management of patients with liver cirrhosis however differing opinions exist amongst hepatologists. Critical illness causes changes in the rates of synthesis and degradation of albumin and this illness also alters the distribution of albumin protein between intravascular and extravascular spaces. The human albumin level which falls in early part of critical illness will not easily rise again until the recovery phase of that illness. Giving exogenous albumin to increase the intravascular albumin concentration during critical illness is beneficial, although the kinetics of albumin given intravenously will differ greatly between critically ill-patients and healthy individuals. This review aims to discuss current opinion, interest and clinical application of albumin infusion therapy and will inspect the role of albumin in health and critical illness.Bangladesh Crit Care J September 2018; 6(2): 88-91

The presence of both 46, XX and 46, XY cell lines in a person is a very rare condition which is known as either chimerism or mosaicism. These conditions usually determined in early childhood during investigation of ambiguous genitalia. Our case is probably the first such report case in our country. Our case was ten months aged child, born to non-consanguinous couple referred to Cytogenetics unit of Immunology Department of BIRDEM General Hospital for chromosomal analysis and Karyotyping with the chief complaint of right sided undescended testis. He was normal looking and playful, presenting complaint was small penis with abnormal urethral opening and absence of one testis since birth. His developmental milestones were normal and intelligence was average. There was no history of congenital and genetic diseases in their family. On examination of the external genitalia the following features were noticed: stretched penile length (SPL) 3.5 cm with penoscrotal hypospadiasis. Right sided testis was not palpable as undescended and left sided testis was palpable in scrotum , volume of which was 2 to 3 ml.Bangladesh Crit Care J September 2018; 6(2): 111-113
Benefits of focus group discussions beyond online surveys in course evaluations by medical students in the United States: a qualitative study
Authors: Brandl Katharina , Rabadia Soniya V. , Chang Alexander , Mandel Jess
Published: October 2018

In addition to online questionnaires, many medical schools use supplemental evaluation tools such as focus groups to evaluate their courses. Although some benefits of using focus groups in program evaluation have been described, it is unknown whether these inperson data collection methods provide sufficient additional information beyond online evaluations to justify them. In this study, we analyze recommendations gathered from student evaluation team (SET) focus group meetings and analyzed whether these items were captured in open-ended comments within the online evaluations. Our results indicate that online evaluations captured only 49% of the recommendations identified via SETs. Surveys to course directors identified that 74% of the recommendations exclusively identified via the SETs were implemented within their courses. Our results indicate that SET meetings provided information not easily captured in online evaluations and that these recommendations resulted in actual course changes.
Weather Impact on Airport Performance
Authors: Schultz Michael , Lorenz Sandro , Schmitz Reinhard , Delgado Luis
Published: October 2018

Weather events have a significant impact on airport performance and cause delayed operations if the airport capacity is constrained. We provide quantification of the individual airport performance with regards to an aggregated weather-performance metric. Specific weather phenomena are categorized by the air traffic management airport performance weather algorithm, which aims to quantify weather conditions at airports based on aviation routine meteorological reports. Our results are computed from a data set of 20.5 million European flights of 2013 and local weather data. A methodology is presented to evaluate the impact of weather events on the airport performance and to select the appropriate threshold for significant weather conditions. To provide an efficient method to capture the impact of weather, we modelled departing and arrival delays with probability distributions, which depend on airport size and meteorological impacts. These derived airport performance scores could be used in comprehensive air traffic network simulations to evaluate the network impact caused by weather induced local performance deterioration.

Published: October 2018

Long-range vocal communication in socially monogamous titi monkeys is mediated by the production of loud, advertising calls in the form of solos, duets, and choruses. We conducted a power spectral analysis of duets and choruses (simply “duets” hereafter) followed by linear discriminant analysis using three acoustic parameters—dominant frequency of the combined signal, duet sequence duration, and pant call rate—comparing the coordinated vocalizations recorded from 36 family groups at 18 sites in Bolivia, Peru and Ecuador. Our analysis identified four distinct duetting patterns: (1) a donacophilus pattern, sensu stricto, characteristic of P. donacophilus, P. pallescens, P. olallae, and P. modestus; (2) a moloch pattern comprising P. discolor, P. toppini, P. aureipalatii, and P. urubambensis; (3) a torquatus pattern exemplified by the duet of Cheracebus lucifer; and (4) the distinctive duet of P. oenanthe, a putative member of the donacophilus group, which is characterized by a mix of broadband and narrowband syllables, many of which are unique to this species. We also document a sex-related difference in the bellow-pant phrase combination among the three taxa sampled from the moloch lineage. Our data reveal a presumptive taxonomic incoherence illustrated by the distinctive loud calls of both P. urubambensis and P. oenanthe within the donacophilus lineage, sensu largo. The results are discussed in light of recent reassessments of the callicebine phylogeny, based on a suite of genetic studies, and the potential contribution of environmental influences, including habitat acoustics and social learning. A better knowledge of callicebine loud calls may also impact the conservation of critically endangered populations, such as the vocally distinctive Peruvian endemic, the San Martin titi, P. oenanthe.
Large-Scale Fine-Grained Bird Recognition Based on a Triplet Network and Bilinear Model
Authors: Zhao Zhicheng , Luo Ze , Li Jian , Wang Kaihua , Shi Bingying
Published: October 2018

The main purpose of fine-grained classification is to distinguish among many subcategories of a single basic category, such as birds or flowers. We propose a model based on a triple network and bilinear methods for fine-grained bird identification. Our proposed model can be trained in an end-to-end manner, which effectively increases the inter-class distance of the network extraction features and improves the accuracy of bird recognition. When experimentally tested on 1096 birds in a custom-built dataset and on Caltech-UCSD (a public bird dataset), the model achieved an accuracy of 88.91% and 85.58%, respectively. The experimental results confirm the high generalization ability of our model in fine-grained image classification. Moreover, our model requires no additional manual annotation information such as object-labeling frames and part-labeling points, which guarantees good versatility and robustness in fine-grained bird recognition.
Atmospheric Chemistry of 2-Methoxypropene and 2-Ethoxypropene: Kinetics and Mechanism Study of Reactions with Ozone
Authors: Lv Chen , Du Lin , Tsona Narcisse , Jiang Xiaotong , Wang Wenxing
Published: October 2018

Rate coefficients at ambient temperature and atmospheric pressure for the reaction of ozone with 2-methoxypropene (2-MPE) and 2-ethoxypropene (2-EPE) were determined in an evacuable 100 L Teflon reaction chamber using absolute and relative rate methods. The product experiments were carried out using a 50 L Teflon reaction chamber in conjunction with FTIR as the detection technique. The rate coefficients (k in units of cm3 molecule−1 s−1) obtained are 1.18 ± 0.13 × 10−17 and 1.89 ± 0.23 × 10−17 for reactions with 2-MPE and 2-EPE, respectively. The effects of the alkoxy group on the gas-phase reactivity of alkyl vinyl ethers toward ozone are compared and discussed. The major ozonolysis products are methyl acetate, formaldehyde and CO2 for 2-MPE, and ethyl acetate, formaldehyde and CO2 for 2-EPE. Possible mechanisms for the two vinyl ethers are proposed based on the observed reaction products. Additionally, atmospheric lifetimes of 32 h and 21 h for 2-MPE and 2-EPE were estimated based on the measured rate constants and the ambient tropospheric concentration of ozone, respectively. The obtained values of the lifetimes indicate that the reaction with ozone is an important loss process for these vinyl ethers in the atmosphere, especially in polluted areas.
Influence of Soil Management on the Red Grapevine (Vitis vinifera L.) Mencía Must Amino Acid Composition and Wine Volatile and Sensory Profiles in a Humid Region

Published: October 2018

Adopting cover crops for vineyard soil management can provide several benefits, including soil protection, reductions in vine vigor, and enhancements in berry composition. However, the effects of this practice on wine aroma have seldom been addressed. This study aimed to determine the influence of different cover crops and soil tillage on the must and wine amino acid composition and wine volatile compounds of the red cultivar, ‘Mencía’ (Vitis vinifera L.), grown in Northwest Spain. Treatments consisted of soil tillage (ST), native vegetation (NV), English ryegrass (ER), and subterranean clover (SC). Cover crops did not alter the macro-constituents of musts; however, musts from NV and SC tended to lower concentrations of amino acids. Some color attributes of wines were influenced by cover crops in the vineyard. Methanol and trans-linalool oxide (pyran) concentrations in wines were significantly affected by soil management. Professional tasters encountered differences in visual, aroma, and palate descriptors of wines depending on the treatment imposed in the vineyard. These alterations in sensory properties seemed to obey to slight modifications of wine chemical characteristics due to vineyard soil management. According to these results, cover crops might be useful for modulating wine aroma in humid climates.
Palliative Care for Children with Central Nervous System Malignancies
Authors: Baenziger Peter H. , Moody Karen
Published: October 2018

Children with central nervous system (CNS) malignancies often suffer from high symptom burden and risk of death. Pediatric palliative care is a medical specialty, provided by an interdisciplinary team, which focuses on enhancing quality of life and minimizing suffering for children with life-threatening or life-limiting disease, and their families. Primary palliative care skills, which include basic symptom management, facilitation of goals-of-care discussions, and transition to hospice, can and should be developed by all providers of neuro-oncology care. This chapter will review the fundamentals of providing primary pediatric palliative care.

Published: October 2018

The purpose of the present study is to access the linkage between dysregulation of glutamatergic neurotransmission, oxidative metabolism, and serine signaling in age-related cognitive decline. In this work, we evaluated the effect of natural aging in rats on the cognitive abilities for hippocampal-dependent tasks. Oxidative metabolism indicators are glutathione (GSH), malondialdehyde (MDA) concentrations, and cytosolic phospholipase A2 (PLA2) activity. In addition, neurotransmitter amino acid (L-Glutamic acid, γ-aminobutyric acid (GABA), DL-Serine and DL-Aspartic acid) concentrations were studied in brain areas such as the frontal cortex (FC) and hippocampus (HPC). The spatial long-term memory revealed significant differences among experimental groups: the aged rats showed an increase in escape latency to the platform associated with a reduction of crossings and spent less time on the target quadrant than young rats. Glutathione levels decreased for analyzed brain areas linked with a significant increase in MDA concentrations and PLA2 activity in cognitive-deficient old rats. We found glutamate levels only increased in the HPC, whereas a reduced level of serine was found in both regions of interest in cognitive-deficient old rats. We demonstrated that age-related changes in redox metabolism contributed with alterations in synaptic signaling and cognitive impairment.

Published: October 2018

This study aimed to compare the effects of two surface-coating methods on the shear bond strength (SBS) of veneering ceramics (VC) to zirconia. Eighty pre-sintered zirconia cubes were randomly assigned into four study groups: E60S, E60P, N60S, and N60P. The zirconia surface was coated with a mixture of two types of glaze and alumina (<60 μm) by airbrush spraying and fine- brush painting. Surface roughness (Ra), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and SBS measurements (both initial and artificial aged conditions, including one month of water storage) were performed. The Ra results revealed significant differences among all groups (p < 0.001). The N60P group exhibited higher values of Ra (5.717 ± 0.20 µm) and SBS before and after water storage with values of 37.22 ± 4.954 MPa and 34.42 ± 3.977 MPa, respectively. The fine-brush coatings showed significantly higher SBS than that of airbrush coatings, in both initial and artificial conditions. Both coating methods and various coating materials (p < 0.001) produced a significant influence on VC-zirconia SBS. A significant correlation between Ra and SBS (Spearman’s rho = 0.808; p < 0.001) was found. The novel coating by fine-brush painting is a promising surface treatment and an easy technique for obtaining a rougher surface, which subsequently improves the bond strength to VC.
Effect of the Strength of Attraction Between Nanoparticles on Wormlike Micelle- Nanoparticle System
Authors: Shaikh Mubeena
Published: October 2018

The nanoparticle-Equilibrium polymer (or Wormlike micellar) system shows morphological changes from percolating network-like structures to non-percolating clusters with a change in the minimum approaching distance (EVP-excluded volume parameter) between nanoparticles and the matrix of equilibrium polymers. The shape anisotropy of nanoparticle clusters can be controlled by changing the polymer density. In this paper, the synergistic self-assembly of nanoparticles inside equilibrium polymeric matrix (or Wormlike micellar matrix) is investigated with respect to the change in the strength of attractive interaction between nanoparticles. A shift in the point of morphological transformation of the system to lower values of EVP as a result of a decrease in the strength of the attractive nanoparticle interaction is reported. We show that the absence of the attractive interaction between nanoparticles leads to the low packing of nanoparticle structures, but does not change the morphological behavior of the system. We also report the formation of the system spanning sheet-like arrangement of nanoparticles which are arranged in alternate layers of matrix polymers and nanoparticles.

Power Decoupling of a Single Phase DC-AC Dual Active Bridge Converter Based on an Integrated Bidirectional Buck/Boost Stage

Published: October 2018

In single phase DC-AC systems, double-line-frequency power ripple appears at the DC side inherently. Normally a large electrolytic capacitor can be used to reduce the power ripple at the DC side. But there are several problems with this method as it decreases the power density and reliability of the converter. In addition, a double-line-frequency current ripple appears in case a voltage source serves at the DC side, which is undesired in specific applications. This paper proposes a single phase DC-AC DAB (dual active bridge) converter with an integrated buck/boost stage for power decoupling purpose under low power condition. The proposed active power decoupling method is able to completely eliminate the double-line-frequency power ripple at the DC side. Therefore, a constant DC current can be obtained for requirements in specific DC-AC applications.
Energy Management in Buildings with Intermittent and Limited Renewable Resources
Authors: Barata Filipe , Igreja José
Published: October 2018

This work reports a contribution, in a model predictive control multi-agent systems context, introducing a novel integrative methodology to manage energy networks from the demand-side point of view, in the strong presence of intermittent energy sources, including energy storage in households or car batteries. In particular, the article presents a control-based solution for indoor comfort, which, in addition, optimizes the usage of a limited shared energy resource. The control management is applied, in a distributed way, to a set of so-called thermal control areas (TCAs) and demand units, with the objective of minimizing the cost of energy while maintaining the indoor temperature within the comfort zone bounds, and simultaneously not exceeding a limited amount of shared renewable energy. The thermal control areas are, in general, thermodynamically connected, and are also coupled by energy interrelation constraints established in the particular optimization solution. Energy management is performed with a fixed sequential order established from a previously carried out auction, wherein the bids are made by each unit’s demands, acting as demand-side management agents, based on the daily energy price. The developed solution is explained by a basic algorithm that has been applied to different scenarios, and the results have been compared so as to illustrate the benefits and flexibility of the proposed approach, showing less energy consumption and a 37% cost saving.
Electric Vehicle Charging Scheduling by an Enhanced Artificial Bee Colony Algorithm
Authors: García Álvarez Jorge , González Miguel Ángel , Rodríguez Vela Camino , Varela Ramiro
Published: October 2018

Scheduling the charging times of a large fleet of Electric Vehicles (EVs) may be a hard problem due to the physical structure and conditions of the charging station. In this paper, we tackle an EV’s charging scheduling problem derived from a charging station designed to be installed in community parking where each EV has its own parking lot. The main goals are to satisfy the user demands and at the same time to make the best use of the available power. To solve the problem, we propose an artificial bee colony (ABC) algorithm enhanced with local search and some mating strategies borrowed from genetic algorithms. The proposal is analyzed experimentally by simulation and compared with other methods previously proposed for the same problem. The results of the experimental study provided interesting insights about the problem and showed that the proposed algorithm is quite competitive with previous methods.
Predicting Tree Diameter Distributions from Airborne Laser Scanning, SPOT 5 Satellite, and Field Sample Data in the Perm Region, Russia

A tree list is a list of trees in the area of interest containing, for example, the species, diameter, height, and stem volume of each tree. Tree lists can be used to derive various characteristics of the growing stock, and are therefore versatile and informative sources of data for several forest management purposes. Especially in heterogonous and unmanaged forest structures with multiple species, tree list estimates imputed from local reference field data can provide an alternative to mean value estimates of growing stock (e.g., basal area, total stem volume, mean tree diameter, mean tree height, and number of trees). In this study, reference field plots, airborne laser scanning (ALS) data, and SPOT 5 satellite (Satellite Pour l’Observation de la Terre) imagery were used for tree list imputation applying the k most similar neighbors (k-MSN) estimation method in the West Ural taiga region of the Russian Federation for diameter distribution estimation. In k-MSN, weighted average of k field reference plots with highest similarity between field reference plot and target (forest grid cell, or field plot) based on ALS and SPOT 5 features were used to predict the mean values of growing stock and tree lists for the target object simultaneously. Diameter distributions were then constructed from the predicted tree lists. The prediction of mean values and diameter distributions was tested in 18 independent validation plots of 0.25–0.5 ha in size, whose species specific diameter distributions were measured in the field and grouped into three functional groups (Pines, Spruce/Fir, Broadleaf Group), each containing several species. In terms of root mean squared error relative to mean of validation plots, the accuracy of estimation was 0.14 and 0.17 for basal area and total stem volume, respectively. Reynolds error index values and visual inspection showed encouraging results in evaluating the goodness-of-fit statistics of the estimated diameter distributions. Although estimation accuracy was worse for functional group mean values and diameter distributions, the results indicate that it is possible to predict diameter distributions in forests of the test area with the tested methodology and materials.

Forecasting commodities and especially oil prices have attracted significant research interest, often concluding that oil prices are not easy to forecast and implying an efficient market. In this paper, we revisit the efficient market hypothesis of the oil market, attempting to forecast the West Texas Intermediate oil prices under a machine learning framework. In doing so, we compile a dataset of 38 potential explanatory variables that are often used in the relevant literature. Next, through a selection process, we build forecasting models that use past oil prices, refined oil products and exchange rates as independent variables. Our empirical findings suggest that the Support Vector Machines (SVM) model coupled with the non-linear Radial Basis Function kernel outperforms the linear SVM and the traditional logistic regression (LOGIT) models. Moreover, we provide evidence that points to the rejection of even the weak form of efficiency in the oil market.
The Montage Rhetoric of Nordahl Grieg’s Interwar Drama
Authors: Krouk Dean
Published: October 2018

This essay explains the modernist montage rhetoric of Nordahl Grieg’s 1935 drama Vår ære og vår makt in the context of the playwright’s interest in Soviet theater and his Communist sympathies. After considering the historical background for the play’s depiction of war profiteers in Bergen, Norway, during the First World War, the article analyzes Grieg’s use of a montage rhetoric consisting of grotesque juxtapositions and abrupt scenic shifts. Attention is also given to the play’s use of incongruous musical styles and its revolutionary political message. In the second part, the article discusses Grieg’s writings on Soviet theater from the mid-1930s. Grieg embraced innovative aspects of Soviet theater at a time when the greatest period of experimentation in post-revolutionary theater was already ending, and Socialist Realism was being imposed. The article briefly discusses Grieg’s controversial pro-Stalinist, anti-fascist position, before concluding that Vår ære og vår makt represents an important instance of Norwegian appropriation of international modernist and avant-garde theater.

Ornamental horticulture businesses in the United States (U.S.) face challenges to stay economically viable, particularly in rural areas. Marketing with new-media tools (e.g., websites, HTML newsletters, social media, and blogs) has the potential to increase sales over traditional methods of advertising. A survey was conducted to gauge the extent of the use of new-media marketing by ornamental horticulture businesses across the U.S. Responses from 161 businesses showed that marketing practices varied widely across business size in terms of expenses and the labor hours allocated. A majority of the sample (89%) were involved in new-media marketing, and all new-media users made use of at least one new-media tool. Facebook was used by more than 90% of new-media users, followed by the business’ own website, which was used by 82% of respondents. Respondents’ perception of how various new-media marketing tools affected sales followed the extent of use, in general.
