Characterization of Triboelectric Charge Generation between PTFE and Nylon after Repeated Contacts
Authors: Kleyman Gleb , Kang Tong , Twiefel Jens , Voit Walter 
Published: April 2018

Abstract
The charge generation between PTFE and Nylon 6,6 has been analyzed under different settings of temperature, humidity and mechanical load. It is found that the charging characteristics of the sample materials in terms of the parameters investigated in this study (e.g. temperature, relative humidity and applied force) are linear. Furthermore, the experimental results show that the proportionality factor between applied load and maximum achievable surface charge is affected by the sample temperature. As we show this fact is most likely attributed to the strongly temperature-dependent elastic properties of polymeric materials. The discoveries lead us to a mathematical formulation for the surface charge density which allows the investigation of maximum charge density for every single operating point within the parameter variation limits. The model parameter for two different structured material pairs are obtained from measurements and applied to the mathematical formulation. The theoretical data demonstrates that the proportionality factor between sample temperature and surface charge is strongly affected by relative humidity.
Science de l’entrelacement des formes, science suprême, science des hommes libres : la dialectique dans leSophiste253b-254b
Authors: Zaks Nicolas 
Published: April 2018

AbstractDespite intensive exegetical work, Plato’s description of dialectic in theSophiststill raises many questions. Through a close reading of this passage that contextualizes it in the general organisation of theSophist, this paper provides answers to these questions. After presenting the difficult text, I contend that the “vowel-kinds” are necessary (but not individually sufficient) conditions for the blending of kinds. Then, I interpret the “cause of divisions” mentioned by the Stranger as the kinds responsible of the dichotomous division in the first half of the dialogue. In the next part, I show that 235d5-e2 does not describe a procedure of “meta-divison” as some commentators have it, but that it describes the method of division itself. Finally, I connect the difficulty and the obscurity of the passage to the fact that dialectic is the supreme science and I explain why dialectic is the science of free men.
Cloud manufacturing: a service-oriented manufacturing paradigm. A review paper
Authors: Siderska Julia , Jadaan Khair S. 
Published: April 2018

Abstract
This paper introduces cloud manufacturing (CMfg) as a new manufacturing paradigm that joins the emerging technologies – such as the Internet of Things, cloud computing, and service-oriented technologies – for solving complex problems in manufacturing applications and performing large-scale collaborative manufacturing. Using scientific publications indexed in Scopus database during the period 2012–2017, the concept and fundamentals of CMfg are presented and discussed given the results of the most recent research. While focusing on the current state of the art, the recent research trends within CMfg concept were also identified. The review involved the methods of bibliometric analysis and network analysis. A prototype of CMfg and the existing related work conducted by various researchers are presented, and the map of co-occurrence is introduced to indicate the most commonly occurring issues related to the “cloud manufacturing” term. The VOSviewer software was used for this purpose. Finally, cloud-based manufacturing areas for further research are identified.
Binge drinking in relation to services – bibliometric analysis of scientific research directions
Authors: Glińska Ewa , Siemieniako Dariusz 
Published: April 2018

Abstract
The article aims to identify scientific research areas within which the subject matter of binge drinking in relation to services is addressed, based on bibliometric data analysis characterising scientific publications indexed by the Scopus database. To achieve the aim, authors use different techniques of the bibliometric analysis with the support of the VOSviewer software. Results of the literature review on binge drinking show that harmful binge drinking behaviour is a subject of intervention services, which are undertaken by governmental and non-governmental institutions. As a theoretical contribution of the research part of the paper, it was proposed to qualify five categories containing the issue of binge drinking in relation to services, such as binge drinking consequences, the culture of alcohol consumption, alcohol versus risky sexual behaviours, alcohol intoxication and binge drinking, and the use of other substance among young people.

Published: April 2018

AbstractObjectiveThis meta-analysis aims to evaluate the effects of traditional Chinese medicine (TCM) nursing combined with conventional nursing in patients with chronic obstructive pulmonary disease (COPD).MethodsData were collected from the databases of PubMed, Embase, the Cochrane Library, Web of Science, Google Scholar, China National Knowledge Infrastructure (CNKI), WanFang Data (WF) and VIP Database, including literature regarding the effects of TCM nursing combined with conventional nursing in patients with COPD published before January 2017. The Jadad scale was used to assess the quality of the eligible literature. The weighted mean differences and odds ratios were used to analyze St. George’s Respiratory Questionnaire (SGRQ) scores, pulmonary function, hospital stay, and clinical efficacy.ResultsTwenty-three randomized controlled trials comprising 3116 cases (TCM nursing combined with the conventional nursing group: 1559; conventional nursing group: 1557) met the inclusion criteria. TCM nursing combined with conventional nursing was associated with a lower SGRQ score, higher forced expiratory volume in 1 second (FEV1) value, higher FEV1/forced vital capacity (FVC) value, higher FEV1% value, higher FEV1 predicted value, shorter hospital stay, and preferable clinical efficacy.ConclusionsTCM nursing combined with conventional nursing emphasized that dialectical nursing can be performed preferably in patients with COPD.
Joining Patterns Across Party Factions in the US Congress
Authors: Thomsen Danielle M. 
Published: April 2018

AbstractHow does the influence of party factions change over time? This article only begins to tackle this question by looking at which party caucuses newly elected members join. I focus on joining patterns in the current 115th Congress to shed light on which factions are more or less influential in Congress today. I show, first, that almost all incoming members joined an ideological faction when they entered office. Furthermore, the Republican Study Committee attracted the most incoming Republicans; the New Democratic Coalition and the Congressional Progressive Caucus attracted the most incoming Democrats. The moderate factions lagged behind the more conservative and liberal factions in the Republican and Democratic parties, respectively. These joining patterns of newly elected members have important implications for the current and future influence that factions can expect to have in the party and chamber.

Published: April 2018

Abstract
In this paper a lumped element model of RF MEMS capacitive switches which is scalable with the lateral dimensions of the bridge is proposed. The dependence of the elements of the model on the bridge dimensions is introduced by using one or more artificial neural networks to model the relationship between the bridge dimensions and the inductive and resistive elements of the lumped element model. The achieved results show that the developed models have a good accuracy over the whole considered range of the bridge dimension values.
The word problem of ℤ n is a multiple context-free language
Authors: Ho Meng-Che 
Published: April 2018

Abstract
The word problem of a group

{G=\langle\Sigma\rangle}

can be defined as the set of formal words in

{\Sigma^{*}}

that represent the identity in G. When viewed as formal languages, this gives a strong connection between classes of groups and classes of formal languages. For example, Anīsīmov showed that a group is finite if and only if its word problem is a regular language, and Muller and Schupp showed that a group is virtually-free if and only if its word problem is a context-free language. Recently, Salvati showed that the word problem of

{\mathbb{Z}^{2}}

is a multiple context-free language, giving the first example of a natural word problem that is multiple context-free, but not context-free. We generalize Salvati’s result to show that the word problem of

{\mathbb{Z}^{n}}

is a multiple context-free language for any n.

On the Cauchy problem for a generalized nonlinear heat equation
Authors: Baaske Franka , Schmeißer Hans-Jürgen 
Published: April 2018

Abstract
The paper is concerned with the Cauchy problem for a nonlinear generalized heat equation which is related to the generalized Gauss–Weierstrass semigroup via Duhamel’s principle. For the initial data we assume that they belong to some fractional Sobolev spaces. We study the existence and uniqueness of mild and strong solutions which are local in time. Moreover, they are smooth functions and belong to Lebesgue spaces with respect to the space variable. We use both fixed point arguments and mapping properties of the generalized Gauss–Weierstrass semigroup. Finally, we study the well-posedness of the problem.

Published: April 2018

AbstractSpecies identification is fundamentally important within the fields of biology, biogeography, ecology and conservation. The genusGeraniumL. (Geraniaceae) comprises about 430 species distributed throughout most parts of the world. According to the most recent treatments, subg.Geraniumis the largest subgenus with over 370 species classified in ten sections. The subg.Geraniumis represented in Iran by 13 species. These species are grouped 3 sections. In spite vast distribution of manyGeraniumspecies that grow in Iran, there are not any available report on their genetic diversity, mode of divergence and patterns of dispersal.Therefore, we performed molecular (ISSR markers) and morphological studies of 102 accessions from 13 species ofGeranium(subg.Geranium) that were collected from different habitats in Iran. The aims of present study are: 1) can ISSR markers identifyGeraniumspecies, 2) what is the genetic structure of these taxa in Iran, and 3) to investigate the species inter-relationship? The present study revealed that combination of morphological and ISSR data can identify the species.
Grazing, abandonment and frequent mowing influence the persistence of the steppe marmot, Marmota bobak
Authors: Savchenko Galina , Ronkin Vladimir 
Published: April 2018

Abstract
The goals of the study were to illustrate how parameters of steppe marmot settlements change after abandonment of livestock grazing, to evaluate differences in vegetation characteristics between grazed and abandoned habitats, to find the links between these characteristics and the persistence of marmot settlements and to establish whether it is possible to maintain the food base of marmots by applying frequently repeated mowing. Data were collected in 1991-2016 in the steppe marmot (Marmota bobak) settlement in the Regional Landscape Park “The Velykyi Burluk-Steppe” (Kharkiv Region, Northeastern Ukraine). We found that grazing prolongs the period of active plant growth and supports a regrowth during periods of intensive feeding of all age groups of marmots. In abandoned habitats the vegetation period ended before the end of active feeding of reproductive females and juveniles. This resulted in lower reproductive success, which determines a decrease in the population and may in the future result in a larger decline of settlements. Frequently repeated mowing by a lawnmower at a cutting height of 6-9 cm prolongs the vegetation period and maintains a water content in the plants similar to that of grazed habitats throughout the active season of steppe marmots.
Biodiversity of herbaceous vegetation in abandoned and managed sites under protection regime: a case study in the Central Forest Reserve, NW Russia
Authors: Cherednichenko Oxana , Borodulina Valentina 
Published: April 2018

Abstract
The aim of the study is to characterise herbaceous vegetation (meadows and ruderal communities) remaining after several decades of protection and compare it to the vegetation of currently managed local sites in the Central Forest Reserve, Tver Oblast, Russia. Cluster analysis of the communities was based on 209 relevés, while their ecological features were analysed using phytoindication assessment. The analyses revealed four types of herbaceous communities: managed mesic meadows, abandoned mesic meadows, tall-herb meadowsweet communities and ruderal tall-herb communities. These four types differ in management, floristic composition and ecological conditions as well as in coenotic and functional group shares (including forbs, graminoids and woody species). The occurrence of these species groups determines the current state of the herbaceous communities. Our study revealed that mesic meadows have retained all the key meadow features for more than 25 years without any management, although their area has shrunk and shares of coenotic and functional groups have changed. The observed herbaceous communities encompass around 40% of the reserve flora including four red list species and 16 alien species.

Abstract
This paper presents first materials on the fauna and distribution of the terrestrial isopods - woodlice (Oniscidea) inhabiting the central and southern parts of Kostanay Region (Kazakhstan, Northern and Southern Turgai), located in the steppe zone. Most of the specimens of woodlice were collected in the territory of the National Nature Reserve “Altyn Dala”, a new protected area (established in 2012) and in the area of the Naurzum National Nature Reserve (established in 1931, World Heritage Site of UNESCO), on the Stipa lessingiana dry steppe. The list of woodlice includes six species (Crustacea: Isopoda: Oniscidea), belonging to five genera and three families in the study area. Four species are recorded for the first time in Kazakhstan - Desertoniscus subterraneus Verhoeff, 1930, Parcylisticus dentifrons (Budde-Lund 1885), Porcellio scaber Latreille, 1804, and Protracheoniscus major (Dollfus 1903). Distribution characteristics are provided for all of those species recorded in the study area. For the territory of Kazakhstan, according to a literature data, currently 16 species of terrestrial isopods have been recorded.

Published: April 2018

Abstract
The vegetation of the European Natura 2000 protected area of Spercheios river and Maliakos gulf, that includes Mediterranean sclerophyllous shrublands, as well as riverine and coastal habitats, was studied during 2000 and 2014–2015. The vegetation was analysed following the Braun-Blanquet method. Twenty six plant communities were recorded, one of which (Pistacio terebinthi-Quercetum cocciferae) described for the first time. The communities belong to fifteen alliances, fourteen orders and eleven phytosociological classes. The distinguished vegetation units are described, presented in phytosociological tables and compared with similar communities from other Mediterranean countries. Eleven different habitat types were identified. Two of them (“Quercus coccifera woods” and “Reed beds”) are Greek habitat types, while the rest are included in Annex I of the Directive 92/43/EEC. Three of the latter (1420, 2110, 3170) have a scattered presence in the Natura 2000 network in Greece, while one (3170) is a priority habitat type.
The challenge of abandonment for the sustainable management of Palaearctic natural and semi-natural grasslands
Authors: Valkó Orsolya , Venn Stephen , Żmihorski Michał , Biurrun Idoia , Labadessa Rocco , Loos Jacqueline 
Published: April 2018

Abstract
Disturbance by biomass removal is a crucial mechanism maintaining the diversity of Palaearctic grasslands, which are unique biodiversity hotspots. The century-long traditional land use of mowing, grazing and burning, has been fundamentally changed in many parts of the Palaearctic. Due to socio-economic changes, large areas of former pastures and meadows have been abandoned, leading to a succession towards secondary scrublands or forest and the encroachment of competitor grass species, all leading to a decrease in biodiversity. Here we report the causes and consequences of the cessation of traditional grassland management regimes, provide strategies for reducing the impact of abandonment and consider these from the perspective of sustainability. We consider the possibilities for initiating sustainable management regimes in the contemporary socio-economic environment, and discuss the prospects and limitation of alternative management regimes in the conservation of grassland biodiversity. These themes are also the core topics of this Special Feature, edited by the EDGG. We hope that this Special Feature will encourage steps towards more sustainable strategies for the conservation of Palaearctic grasslands and the integration of the sustainability perspective into their conservation.

Abstract
Between 2011 and 2016 we surveyed 42 sites of coastal salt marshes of Croatia. We confirmed the occurrence of several rare and endangered plant species. Ten of them are included in the Red List of Croatia; critically endangered (CR) Eleocharis uniglumis, Triglochin barrelieri and T. maritima, endangered (EN) Carex divisa and C. extensa, vulnerable (VU) Parapholis incurva, Salsola soda and Suaeda maritima and category data deficient (DD) Limonium virgatum and Puccinellia festuciformis. We also report localities of other rare taxa of salt marshes like Allium telmatum, Tripolium pannonicum subsp. tripolium, Juncus gerardii, Parapholis filiformis, Plantago cornuti, Samolus valerandi and Scorzonera parviflora. Several plant species are endangered. Their habitats, salt marshes were converted into fields or destructed by construction for developing tourist infrastructure. Today only a part of the remained areas are under protection.
