Clinical characteristics and outcome of twin pregnancies complicated by single intrauterine death
Authors: Luo Qiong , Han Xiujun 
Published: March 2017

Abstract:

Aim:
To investigate the clinical characteristics and outcome of twin pregnancies complicated by single intrauterine death and how to improve the outcomes of surviving twins. Three thousand three hundred and eighty-four women who delivered twin pregnancies at Women’s Hospital, Zhejiang University, School of Medicine were included. Clinical and demographic data on gestational age, etiology, morbidity and mortality for mothers and fetuses were collected.

Results:
The median gestational age for detecting a single intrauterine death in twin pregnancy was 29 weeks and the average gestational age of pregnancy termination was 32 weeks. At least one complication occurred in 93 of 134 mothers (69.4%). The leading causes of a single intrauterine death were umbilical cord abnormality (21.6%), congenital anomalies (17.9%), twin-twin transfusion syndrome (TTTS) (8.2%) and velamentous placenta (7.4%). Of the 134 cases, in 115 cases the remaining twin survived. The birth weight of the surviving twin was significantly higher in pregnancies that continued for more than 1 week after single intrauterine death compared to that ended within 1 week after intrauterine death.

Conclusions:
Extension of gestation for the surviving twin fetus as long as possible in ensuring the health of the surviving twin and mother, will improve the prognosis of surviving twin after a single intrauterine death.
Bayesian survival analysis of batsmen in Test cricket
Authors: Stevenson Oliver George , Brewer Brendon J. 
Published: March 2017

AbstractCricketing knowledge tells us batting is more difficult early in a player’s innings but becomes easier as a player familiarizes themselves with the conditions. In this paper, we develop a Bayesian survival analysis method to predict the Test Match batting abilities for international cricketers. The model is applied in two stages, firstly to individual players, allowing us to quantify players’ initial and equilibrium batting abilities, and the rate of transition between the two. This is followed by implementing the model using a hierarchical structure, providing us with more general inference concerning a selected group of opening batsmen from New Zealand. The results indicate most players begin their innings playing with between only a quarter and half of their potential batting ability. Using the hierarchical structure we are able to make predictions for the batting abilities of the next opening batsman to debut for New Zealand. Additionally, we compare and identify players who excel in the role of opening the batting, which has practical implications in terms of batting order and team selection policy.
Shifting of “expert” and “novice” roles between/within two languages: Language socialization, identity, and epistemics in family dinnertime conversations
Authors: Takei Noriko , Burdelski Matthew 
Published: March 2017

AbstractThis article explores the construction and shifting of “expert” and “novice” roles between and within two languages (Japanese and English). Taking a language socialization perspective while drawing upon insights from conversation analysis on epistemics in interaction, it analyzes seven hours of audio recordings of dinnertime talk in a Japanese-speaking immigrant family with a university-aged adult daughter living together in Australia. The analysis identifies several key communicative practices, such as word definitions and repair, which participants deploy in displaying epistemic stances that constitute the self and family members as possessing relatively more or less knowledge and expertise (epistemic status) with respect to these two languages. The findings reveal the dynamics of language socialization in a bilingual/immigrant setting in which the relative roles of expert and novice emerge, shift, and are negotiated in interaction. In conclusion, the findings are discussed in relation to language expertise, power and hierarchy, agency and bidirectional language socialization.

Published: March 2017

Abstract

Reimeria ovata (Hust.) Levkov & Ector was found during field research conducted from 2013 to 2015 on the Wołosaty stream and its selected tributaries. Valves measured in the studied material are narrower than valves described in the currently available literature and have more striae per 10 µm. Specimens of R. ovata observed under a light microscope were morphologically very similar to those of R. sinuata, particularly in the case of small individuals. The precise distinction between these two species was only possible under SEM. R. ovata has been found in cold, oligotrophic waters, highly saturated with oxygen, with alkaline or circumneutral pH, but never in large numbers. The aim of this work was to identify the new locations of R. ovata and to determine morphological and ecological characteristics of this species.
Mainstreaming multiple uses of chemicals in chemistry teacher education programs of Africa
Authors: Engida Temechegn 
Published: March 2017

Abstract:
Many compounds can be used for or manipulated to serve a variety of purposes. Chemistry teachers and the chemistry curricula they use, however, do not directly deal with the idea of the use, misuse, and abuse of multi-use chemicals. This paper therefore attempts to explore strategies in mainstreaming the concepts of multi-use chemicals in Chemistry teacher education programs. It is believed that teacher education programs have multiplier effects since they are intended to cover both pre- and in-service chemistry teachers.

Abstract:
Rational design of title ligands and their transition metal complexes gave the high effective catalysts for hydrogen economy and perspective “stimuli-responsive” luminescent materials. Together with the above novel cyclic aminomehtylphospine ligands have showed a row of unpredicted properties like spontaneous formation of macrocyclic molecules, unique reversible slitting of macrocycles on to the smaller cycles, rapid interconversion of the isomers catalyzed by both acids and transitional metals, bridging behavior of usually chelating ligands and unexpected high influence of handling substituents on N-atoms on to the catalytic and luminescent properties of P-complexes.
The challenge of methods of thermal analysis in solid state and materials chemistry
Authors: Drábik Milan 
Published: March 2017

Abstract
Thermogravimetry (TG) and differential thermal analysis (DTA) are traditional, but still useful, experimental techniques for obtaining information in the realms of materials and solid state chemistry. This paper presents two case studies (many more could be cited) to illustrate the strengths (and limitations) of these techniques: (1) Iron doping of clinoptilolite (the most common zeolite): the typical parameters of both components appear clearly in the TG and DTA curves. The decrease of the Tmax value of the structurally-typical DTA effect of FeOOH by approximately 100°C is attributed to the weakening of chemical bonds in FeOOH due to the incorporation of the doping component into the structure of this zeolite. (2) Macrodefect-free (MDF) materials: the results of both TG and DTA unambiguously locate the typical temperature range of the decomposition of the P{4}–O–Al/Fe{6} cross-links within the interval of 200–300°C. The presence of cross-links is shown by the DTA data while the TG data can be used to measure the degree of cross-linking, which is valuable information when studying both raw mixes and the final materials for a variety of MDF materials.
Prussian geological maps of Northern Poland in the archives of the Polish Geological Institute and their current application in geology
Authors: Małka Anna , Jegliński Wojciech , Relisko-Rybak Justyna 
Published: March 2017

AbstractThe article characterizes first general geological (lithological-stratigraphical) maps presenting Quaternary deposits in Northern Poland. These were the maps of territory of the Prussian partition, elaborated by German geologists from Prussian Geological Survey “Königlich Preussische Geologische Landesanstalt”. After Poland regained its independence they became a basis for many Polish geological publications. The article discusses the chronology and objectives of the main cartographic works of German geologists operating in the area of present-day Northern Poland (general and detailed geological maps) and briefly presents the methodology of geological mapping of lowlands at the scale of 1:25,000.The authors present initial results of the sheet inventory of the Prussian geological map at the scale of 1:25,000 owned by the Polish Geological Institute - National Research Institute (PGI-NRI). Quick search of Prussian map sheets is enabled with the created GIS data base which contains basic information about sheets, i.e. map title, year, author/authors, sheet title and topographic map designation. The applied relations between data and their spatial reference make it possible to dynamically generate section map and perform spatial analyses of any type. The multiuser geodatabase was created using ESRI and Oracle technologies. Until now the inventory covered the sheets available in the archives of the Marine Geology Branch of PGI-NRI in Gdańsk and the Pomeranian Branch of PGI-NRI in Szczecin.The article also presents examples of Prussian topographic and geological maps used to realize the objectives of the surface geology of Poland. Sheets of Prussian maps are a very valuable basis for elaboration of general and detailed Polish geological maps. Prussian maps make it possible to recreate the earlier geological, geomorphological and hydrographic picture of terrains which are now highly developed and antropogenically transformed. They are often used for the purpose of various time-spatial analyses, mostly to evaluate the dynamics and pace of erosional and accumulative coastal processes of the Southern Baltic coast. The maps of this type help to reconstruct and forecast the development of river mouths and to recreate the location of excavations and inactive open-cut mines of sand, gravel, clay, brown coal and amber. Old maps documenting the exact location of exploited deposits have practical application in geo-tourism.

Published: March 2017

Abstract:
A non-isothermal analysis of calendering by using the Rabinowitsch fluid model is presented in this article. The flow equations are simplified by utilizing the lubrication approximation theory. The exact expressions of velocity and pressure gradient are obtained. The pressure distribution and engineering quantities are computed numerically by employing the Runge-Kutta algorithm. The temperature distribution is obtained by solving the energy equation numerically using the hybrid numerical method. The influence of the involved parameters on the velocity profile, pressure, pressure gradient and mechanical quantities such as roll-separating force, power function and exiting sheet thickness are shown graphically. The temperature distribution at various axial points is also shown through graphs.
Influence of mold temperature and process time on the degree of cure of epoxy-based materials for thermoset injection molding and prepreg compression molding
Authors: Deringer Tim , Gröschel Christian , Drummer Dietmar 
Published: March 2017

AbstractA new hybrid process for fiber-reinforced plastics based on thermosets combining master-forming and forming in one tool is currently undergoing development. The advantage of this technique is the integrated forming and overmolding of a thermoset-based continuous fiber-reinforced sheet in one step. Although both components are epoxy based, the resin formulations slightly differ and thus require individual curing parameters. For successful combination into one process, it is essential to investigate both components in relation to the processing parameters and their influence on the degree of cure. Besides the influence on the forming and filling behavior, the degree of cure also has an effect on the resulting mechanical properties. In this investigation, the influence of curing time and temperature on the degree of cure of epoxy-based materials was investigated with regard to identifying a process window for a process combination of master-forming and forming.
Recommendations for pathological diagnosis on biopsy samples from peritoneal dialysis patients
Authors: Kawanishi Kunio , Honda Kazuho , Hamada Chieko 
Published: March 2017

AbstractPeritoneal dialysis (PD) has been established as an essential renal replacement therapy for patients with end stage renal disease during the past half century. Histological evaluation of the peritoneal membrane has contributed to the pathophysiological understanding of PD-related peritoneal injury such as peritonitis, fibrosis, and encapsulating peritoneal sclerosis (EPS). Hyalinizing peritoneal sclerosis (HPS), also known as simple sclerosis, is observed in almost all of PD patients. HPS is morphologically characterized by fibrosis of the submesothelial interstitium and hyalinizing vascular wall, particularly of the post-capillary venule (PCV). Two histological factors, the thickness of submesothelial compact zone (SMC) and the lumen/vessel ratio (L/V) at the PCV, have been used for the quantitative evaluation of HPS. The measuring system on SMC thickness and L/V ratio is easy and useful for evaluating the severity of HPS. On the other hand, EPS is characterized by unique encapsulation of the intestines by an “encapsulating membrane”. This newly formed membranous structure covers the visceral peritoneum of the intestines, which contains fibrin deposition, angiogenesis, and proliferation of fibroblast-like cells and other inflammatory cells. This review will cover the common understandings of PD-related peritoneal alterations and provide a basic platform for clinical applications and future studies in this field.
Lanthanoides in Glass and Glass Ceramics
Authors: Meinhardt Jürgen , Kilo Martin , Somorowsky Ferdinand , Hopp Werner 
Published: March 2017

AbstractMany types of glass contain lanthanoides; among them, special glass for optical applications is the one with the highest content of lanthanoides. The precise determination of the lanthanoides’ concentration is performed by inductively coupled plasma-optical emission spectrometry (ICP-OES). However, up to now, there are no established standard processes guaranteeing a uniform approach to the lanthanoide analysis. The knowledge of the lanthanoides’ concentrations is necessary on the microscale in some cases, especially if a suitable separation and recycling procedure is to be applied. Here, the analysis is performed by energy-dispersive X-ray (EDX) or wavelength-dispersive X-ray (WDX) analytics in the scanning electron microscope.
Controlled Functionalization of Graphene by Oxo-addends
Authors: Eigler Siegfried , Hirsch Andreas 
Published: March 2017

AbstractThe single carbon layer graphene and especially its oxidized derivatives, such as graphene oxide (GO), are in the focus of research that started already 150 years ago [1–6]. GO is a collective term for various single layers of graphene (with lattice defects) functionalized by oxo-addends. The type of oxo-groups is not defined, but epoxy and hydroxyl groups dominate the structure in addition to in-plane lattice defects on the percent scale. Those defects are rarely considered in chemical functionalization approaches and it is impossible to distinguish between functionalization of surface oxo-groups and in-plane oxo-groups.This chapter focuses on functionalized derivatives of graphene with an almost intact carbon framework, termed “oxo-functionalized graphene” (oxo-G1, index indicates the number of layers). Avoiding in-plane defects further allows the development of a controlled chemistry of graphene with oxo-addends. However, general approaches of conventional GO chemistry are summarized in a separate section.

Impacts of Geomorphic Disturbances on Plant Colonization in Ebba Valley, Central Spitsbergen, Svalbard
Authors: Stawska Monika 
Published: March 2017

AbstractGlobal warming observed nowadays causes an increase in geomorphic activity in polar regions. Within the areas influenced by cold climatic conditions, relief dynamics and vegetation development are the main landscape shaping processes. The study is limited to the Ebba Valley (78°43’N; 16°37’E) in central Spitsbergen (Svalbard), where geomorphologic observations and vegetation sampling were conducted in 2007. The valley was divided into three zones differentiated by dominating geomorphic activity and stability of deposits. The settlement and the evolution of plant cover have been documented there. The main factors that control well developed vegetation cover within raised marine terraces are frost heave and solifluction. In deeper parts of the valley, aeolian processes dominate and high differentiation of microsite conditions causes high variability in plant coverage. The area close to the Ebba glacier marginal zone is characterized by initial stages of plant colonisation where disturbance to vegetation is mainly caused by hydrological processes.
Semi-Automated Classification of Landform Elements in Armenia Based on SRTM DEM using K-Means Unsupervised Classification
Authors: Piloyan Artak , Konečný Milan 
Published: March 2017

Abstract
Land elements have been used as basic landform descriptors in many science disciplines, including soil mapping, vegetation mapping, and landscape ecology. This paper presents a semi-automatic method based on k-means unsupervised classification to analyze geomorphometric features as landform elements in Armenia. First, several data layers were derived from DEM: elevation, slope, profile curvature, plan curvature and flow path length. Then, k-means algorithm has been used for classifying landform elements based on these morphomertic parameters. The classification has seven landform classes. Overall, landform classification is performed in the form of a three-level hierarchical scheme. The resulting map reflects the general topography and landform character of Armenia.
Mapping Spatio-Temporal Changes in Climatic Suitability of Corn in the Philippines under Future Climate Condition
Authors: Salvacion Arnold R. 
Published: March 2017

AbstractThis study assessed the spatio-temporal changes in corn climatic suitability in the Philippines under future climate condition. Using extracted climatic data from WorldClim database for the country under baseline and future climate condition, changes in corn suitability was assessed using fuzzy logic approach and published rainfall and temperature requirement of the crop. Based on the data, the large portion of the country will experience increase in monthly total rainfall (88%) while increase in monthly mean and minimum temperature under future climate condition is projected for the entire country. These increases in rainfall and temperature resulted in changes of corn climatic suitability in the country depending on the month and location. On the average, changes in rainfall resulted in reduction (8%) and improvement (6%) in corn suitability while increase in temperature resulted in 5% and 0.4% reduction and improvement, respectively.
