Flight control of fruit flies: dynamic response to optic-flow and headwind
Authors: Lawson Kiaran K. K. , Srinivasan Mandyam V.
Published: March 2017

Insects are magnificent fliers that are capable of performing many complex tasks such as speed regulation, smooth landings, and collision avoidance, even though their computational abilities are limited by their small brain. To investigate how flying insects respond to changes in wind speed and surrounding optic flow, the open-loop sensorimotor response of female Queensland fruit flies (Bactrocera tryoni) was examined. 136 flies were exposed to stimuli comprising sinusoidally varying optic flow and air flow (simulating forward movement) under tethered conditions in a virtual reality arena. Two responses were measured: the thrust, and the abdomen pitch. The dynamics of the responses to optic flow and air flow were measured at various frequencies, and modelled as a multicompartment linear system, which accurately captures the fruit flies' behavioural responses. The results indicate that these two behavioural responses are concurrently sensitive to changes of optic flow as well as wind. The abdomen pitch showed a streamlining response, where the abdomen was raised higher as the magnitude of either stimulus was increased. The thrust, on the other hand, exhibited a counter-phase response where maximum thrust occurred when the optic flow or wind flow was at a minimum, indicating that the flies were attempting to maintain an ideal flight speed. When the changes in the wind and optic flow were in phase (i.e. did not contradict each other), the net responses (thrust and abdomen pitch) were well approximated by an equally weighted sum of the responses to the individual stimuli. However, when the optic flow and wind stimuli were presented in counterphase, the flies seemed to respond to only one stimulus or the other, demonstrating a form of ‘selective attention’.

The Regularizing Effect of Lower Order Terms in Elliptic Problems Involving Hardy Potential
Authors: Adimurthi A. , Boccardo Lucio , Cirmi G. Rita , Orsina Luigi
Published: March 2017

We study existence and summability of solutions for elliptic problems with a power-like lower order term and a Hardy potential.We prove that, due to the presence of the lower order term, solutions exist and are more summable under weaker assumptions than those needed for the existence without it.
Kazhdan projections, random walks and ergodic theorems
Authors: Druţu Cornelia , Nowak Piotr W.
Published: March 2017

In this paper we investigate generalizations of Kazhdan’s property (T) to the setting of uniformly convex Banach spaces. We explain the interplay between the existence of spectral gaps and that of Kazhdan projections. Our methods employ Markov operators associated to a random walk on the group, for which we provide new norm estimates and convergence results. This construction exhibits useful properties and flexibility, and allows to view Kazhdan projections in Banach spaces as natural objects associated to random walks on groups.

We give a number of applications of these results. In particular, we address several open questions. We give a direct comparison of properties (TE) and FEwith Lafforgue’s reinforced Banach property (T); we obtain shrinking target theorems for orbits of Kazhdan groups; finally, answering a question of Willett and Yu we construct non-compact ghost projections for warped cones. In this last case we conjecture that such warped cones provide counterexamples to the coarse Baum–Connes conjecture.
Addressing Technology Uncertainties in Battery Energy Storage Sizing Procedures
Authors: Carpinelli Guido , Mottola Fabio , Proto Daniela
Published: March 2017

This paper analyzes the influence of technology uncertainties on the sizing of battery systems. The sizing is based on the minimization of the costs incurred by the end customer and is performed considering demand response applications in the frame of time of use tariffs. The randomness of i) battery round trip efficiency, ii) life time duration, iii) unit costs related to battery capacity, power conversion system, operation and maintenance and replacement is taken into account in order to identify the most convenient solution from an economic and technical point of view. Based on the load requests of actual industrial and residential loads, numerical applications have been performed. The results provided useful information regarding the influence uncertainties have in the choice of a battery energy storage system.
Could the start of the German recession 2008–2009 have been foreseen? Evidence from Real-Time Data
Authors: Heilemann Ullrich , Schnorr-Bäcker Susanne
Published: March 2017

The Great Recession in Germany was noticed only seven months after its onset. This study examines whether the available data could have helped to predict or identify the crisis in real time. After assessing the accuracy of previous recession forecasts, we examine that of forecasts published from April to December 2008 by twelve major national and international forecast institutions and confront them with real-time data from official statistics, major surveys, and indicators. While annual forecasts for 2008 were unusually accurate due to errors of semi-annual forecasts offsetting each other, forecasters failed to observe the onset of the recession in Q2 2008, although from May onward an increasing amount of data indicated that the economy was in recession or was likely about to enter one. Though the data were neither ambiguous nor misleading, forecasters recognised the onset of the recession as late as mid-November, but also failed to warn of a coming recession. The most convincing explanations for these failures to recognize the crisis in time appear to have been the ‘truth effect’ and forecasters’ ‘low priors about the likelihood of a recession’.
Managing irritable bowel syndrome: The impact of micro-physiotherapy
Authors: Grosjean Daniel , Benini Patrice , Carayon Pierre
Published: March 2017

Background

Irritable bowel syndrome (IBS) has a complex pathology, high prevalence and large impact on patients’ quality of life. As conventional therapy may yield unsatisfactory results, a more holistic approach may be desirable. The current study assessed the effect of micro-physiotherapy on the severity of IBS symptoms.

Methods

In a double-blind study, 61 recurrent IBS patients were randomised to two sessions of micro-physiotherapy or sham micro-physiotherapy. Inclusion criteria were the presence of ≥1 IBS symptom from abdominal pain, constipation, diarrhoea or bloating. Exclusion criteria were previous major intestinal surgery and the presence of chronic diseases. The mean patient age was 53.5±15.3 years. Micro-physiotherapy consisted of micro-palpatory examination to identify osteopathic lesions, followed by micro-massage to stimulate self-healing. The control group underwent a sham procedure. The presence and severity of symptoms was assessed at baseline and at 1-month follow-up by the same gastroenterologist.

Results

Two patients did not complete the study. There was a significant difference in percentage of patients that improved after the first session, at 74 % for the micro-physiotherapy group and 38 % for the sham group, respectively (p=0.005). After the second session, the initial improvement was maintained in both groups, although with no further gains, and the differences between the study groups remained significant (p=0.007).

Conclusions

Micro-physiotherapy significantly improves IBS symptoms and should be explored further for use in mainstream healthcare.
ROS-mediated induction of apoptosis by benzoquinone embelin in human colon adenocarcinoma cells HT-29
Authors: Sumalatha Kodandaram , Gowda Mohan , Meenakshisundaram Sreepriya
Published: March 2017

Background

Embelin is a benzoquinone reported to possess anticancer activity in several in vivo and in vitro models of carcinogenesis, especially hematopoietic and prostate malignancy. A detailed investigation on the influence of embelin on epithelial malignancy model system, especially colon adenocarcinoma, is lacking. The objective of the current study is to investigate the antiproliferative, antiinvasive and proapoptotic potential of embelin on colon adenocarcinoma cell line HT-29.

Methods

The effect of embelin (35 µg/mL for 24 h) on cell proliferation was assessed by Sulforhodamine B assay and bromodeoxyuridine incorporation test, antiinvasive effect by Boyden chamber assay and scratch assay. Proapoptotic effects of embelin were determined by studies on DNA fragmentation, annexin V-FITC labeling, TUNEL assay, COMET assay and assay of caspase-3 activity. Influence of embelin on the expression of genes regulating apoptosis (caspase 3 and 9, Bcl-2, Bax, cytochrome C and X-linked inhibitor of apoptosis protein) and migration/invasion (matrix metalloproteinase [MMP]-2 and MMP-9) was investigated by reverse transcription polymerase chain reaction (PCR). Further, the effect of embelin on the levels of reactive oxygen species (ROS), lipid peroxides, nitric oxide, mitochondrial membrane potential and antioxidant status (total reduced glutathione [GSH] and GSH-S-transferase) was evaluated.

Results

Results implicated that embelin treatment inhibited proliferation (IC50 35 µg/mL), induced DNA fragmentation, phosphatidyl serine externalization, increased caspase expression, decreased cell migration and expression of MMPs in HT-29 cells. Interestingly, embelin exhibited prooxidant effect on HT-29 cells and induced excessive ROS generation resulting in apoptotic cell death.

Conclusions

To conclude, embelin treatment could be a promising strategy for the chemotherapy of colon cancer.
Language ideologies on English as a Lingua Franca in Brazil: conflicting positions expressed by undergraduate students
Authors: Carréra Szundy Paula Tatianne
Published: March 2017

Drawing on the concept of ideology proposed by Voloshinov (1929 [1999], Marxismo e filosofia da linguagem: Problemas fundamentais do método sociológico na ciência da linguagem. Trad. Michel Lahud; Yara Frateschi Vieira 9 ed. São Paulo: Editora Hucitec.) and on the notion of language ideology (Woolard 1998, Introduction. In Bambi B. Schieffelin, Kathryn A. Woolard & Paul V. Kroskrity (eds.), Language ideologies practice and theory, 3–47. Oxford: Oxford University Press; Kroskrity 2004, Language ideologies. In Alessandro Duranti (ed.), A companion to linguistic anthropology, 496–517. Blackwell Publishing), this paper addresses language ideologies expressed by participants of an Academic Writing course taught to undergraduate students majoring in English and Portuguese in a public university in Rio de Janeiro, Brazil. The data from which participants’ language ideologies are interpreted come from two literacy events that integrate a wider set of literacy practices (Street 2000, Literacy events and literacy practices. In Marilyn Martin-Jones & Kathryn E. Jones (eds.), Multilingual literacies: Comparative perspectives on research and practice, 17–29. Amsterdam: John Benjamin’s, Street 2009, Ethnography of writing and reading. In David R. Olson & Nancy Torrance (eds.), The Cambridge handbook of literacy, 329–345. Cambridge: Cambridge University Press) in which participants engaged in Moodle, the virtual learning environment of the course. Concerning students’ positions, the analysis depicts how they entextualize ELF scholars’ language ideologies to either (re/de)construct their own standard native-based language ideology about English or to reinforce this same ideology. The paper also examines the stance adopted by the professor in her responses to students’ writings in terms of both her ideological alignment with theories that challenge the role of the native speaker as English expands worldwide and her resistance to naïve and romantic views of this expansion.
Communication courtesy or condescension? Linguistic accommodation of native to non-native speakers of English
Authors: Drljača Margić Branka
Published: March 2017

This paper draws on the perception of English as a lingua franca (ELF) as an activity, rather than a variety, whereby speakers of different lingua-cultural backgrounds respond to the needs of the immediate communicative environment. Such dynamic and context-related nature of ELF involves collaboration and accommodative behaviour of all interlocutors. As the main focus of research on ELF has been interaction predominantly among non-native speakers of English, the present study investigates how native English speakers behave in ELF interaction, that is, whether/how they accommodate their English and what their stance is towards linguistic accommodation. Responses were collected by means of an online questionnaire, yielding 377 respondents in total, who report making adjustments when communicating with non-native speakers, most frequently by enunciating clearly, using fewer idioms and speaking more slowly. The main reasons native speakers give for adjusting their language are promoting mutual intelligibility, showing courtesy and helping the interlocutor hone their English language skills. A fifth of the respondents, however, worry that accommodation might prevent the improvement of non-native speakers’ English proficiency, be perceived as being patronising, and reduce the quality of conversation.

Authors: Ghaffarzadeh Maryam , Ghaedi Hamid , Alipoor Behnam , Omrani Mir Davood , Kazerouni Faranak , Shanaki Mehrnoosh , Labbaf Afsaneh , Pashaiefar Hossein , Rahimipour Ali
Published: March 2017

Background:Coronary artery disease (CAD) is the most common cause of mortality and disability from incommunicable disease in the world. Although the association between the single nucleotide polymorphisms (SNPs) in protein-coding genes and the risk of CAD has been investigated extensively, very few heart-disease associated studies concerning the SNPs in miRNA genes have been reported. The present study was performed to elucidate the association between the pre-microRNA-149 (miR-149) SNP rs2292832 and the risk of CAD in an Iranian population.

Methods:Polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) were performed to identify the genotypes of the miR-149 SNP rs2292832 in 421 unrelated subjects (272 with CAD and 149 controls).

Results:Our analysis revealed that the TT genotype was more frequent in CAD patients than control subjects (P=0.02) implying that TT genotype should be considered as a risk factor in CAD development (TT vs. TC+CC p=0.02, OR=1.88).

Conclusions:The present study suggests that rs2292832-TT in pre-miR-149 is associated with CAD in an Iranian population.
Clinical features of girls with short stature among inv (9), Turner (45, X) and control individuals
Authors: Chen Xuefeng , Wang Xiumin , Dong Guanping , Fu Junfen , Wu Wei , Jiang Youjun
Published: March 2017

Background:

The clinical significance of pericentric inversion of chromosome 9 [inv (9)] remains unclear.

Methods:

This case control study assessed girls with short stature. According to karyotypes, the subjects were divided into inv (9) [46,XX,inv (9)(p12q13) and 46,XX,inv (9)(p11q13)], Turner syndrome (45, X) and control (normal 46, XX) groups, respectively. Detailed clinical features were compared.

Results:

Height standard deviation score (SDS) values at diagnosis were −2.51±0.58, −3.71±2.12 and −2.5±1.24 for inv (9), (45, X) and control groups, respectively (p=0.022). The inv (9) group showed lower body mass index (BMI) values compared with the (45, X) and control groups (F=5.097, p=0.008). Similar growth hormone deficiency (GHD) incidences were found in all groups. Interestingly, height SDS was positively correlated with mother height and patient BMI SDS (r=0.51, p=0.036; r=0.576, p=0.023, respectively) in the inv (9) group. In the (45, X) group, height SDS was positively correlated with birth weight (r=0.392, p=0.039).

Conclusions:

Short stature in inv (9) girls was correlated with low birth weight (LBW) and mother height.
Leptin and adiponectin levels in discordant dichorionic twins at 72 hours of age-associations with anthropometric parameters and insulin resistance
Authors: Milenković Svetlana J. , Mirković Ljiljana B. , Jovandarić Miljana Z. , Milenković Dušan M. , Banković Violeta V. , Janković Borisav Z.
Published: March 2017

Background:

Insulin resistance (IR) in adults has been associated with intrauterine growth restriction (IUGR). Leptin and adiponectin correlations with anthropometric parameters and IR at 72 h in discordant twins were tested.

Methods:

We included 24 discordant (birth weight discordance ≥20% in relation to the heavier cotwin) and 30 concordant (birth weight discordance ≤10%) twins.

Results:

A correlation between leptin (but not adiponectin) level and birth weight (BW), birth length and head circumference in IUGR twins was recorded (p<0.05). Insulin sensitivity (IS) and homeostatic model assessment (HOMA)-IR in IUGR twins were similar to appropriate-for-gestational-age cotwins and unrelated to adipokines. In IUGR twins, adiponectin and insulin associated positively. In larger concordant twins’ leptin level correlated with HOMA-IR and insulin.

Conclusions:

Leptin, but not adiponectin, levels correlate positively with anthropometric parameters in IUGR twins. IR in IUGR twins is unrelated to adipokines in the first few days of life.

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

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

Cricketing 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

This 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.

Morphology of Reimeria ovata (Hust.) Levkov & Ector in comparison with similar Reimeria species
Authors: Noga Teresa , Stanek-Tarkowska Jadwiga , Rybak Mateusz , Kochman-Kędziora Natalia
Published: March 2017

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

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.
Cyclic aminomethylphosphines as ligands. Rational design and unpredicted findings

Published: March 2017

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

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

The 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.

Calendering of non-isothermal Rabinowitsch fluid
Authors: Sajid Muhammad , Siddique Hira , Ali Nasir , Javed Muhammad Asif
Published: March 2017

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

A 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

Peritoneal 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

Many 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

The 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

Global 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

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

This 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.

Published: March 2017

This study analyzed the temporal and spatial changes in land use taking place in two adjacent river valleys, located within the Polish Carpathians. The land use in 1977 and 2009 was presented for selected areas. In one of the valleys, a dam has been operating since 1994 along with a retention reservoir, which is an additional factor influencing the direction and scale of the land use changes. An analysis using GIS techniques showed that the general directions of transformation in both valleys in the land use structure are similar but with different intensity. In studied valleys a decrease of area with agricultural land and gradual increase in the forested area have been observed. In the valley with the reservoir few more changes were noticed. The decrease of the forested area by 5.5% and farmland by 8.2% on the areas submerged by reservoir was observed. The strip fields pattern has been changed into more dispersed. The road network development was also observed, as well as the change of nature of residential/agricultural buildings into residential/recreational.
Assessment of gamma radiation levels and natural radioactivity in soils along a subtropical river basin, China
Authors: Huang Dekun , Yu Tao
Published: March 2017

The activities of natural radionuclides in the environment can be used to assess radiological effects. Monitoring the radiation level in soils is important for public health. It also has important geochemical implications as most of the sediment eroded from river basins is from soil. Therefore, we carried out a soil sampling campaign along a subtropical river basin in southeastern China (Jiulong River). Surface and depth profile soils were collected, and the natural radionuclide activities were measured. The activities of the natural radionuclides 238U, 232Th, and 40K in the surface soils varied from 31.6 to 132.1 Bq kg-dry−1, 37.8 to 174.0 Bq kg-dry−1, and 52.3 to 596.2 Bq kg-dry−1, with average values of 56.7±30.3 Bq kg-dry−1, 86.7±41.3 Bq kg-dry−1, and 352.8±190.6 Bq kg-dry−1, respectively. The absorbed gamma dose in air and the annual effective dose equivalent (AEDE) in surface soils along the river basin were both higher than the world average. In the depth profiles, excess 210Pb (210Pbex) decreased with depth and significant correlation between 210Pbex and TOC was observed, suggesting that they are affected by similar processes (leaching and sorption).
Number 13 / Part I. Music. 1. The Laws of Musical Art as a Resource for The Early Education Methodology
Authors: Morari Marina
Published: March 2017

The supreme function of music in the preschool institution is the educational one. As the development of the child depends on some physiological, psychological, socio-cultural and spiritual laws, so the musical art laws do with the methodology of the musical art process. In this article are characterized some laws through which is revealed the sounding, temporal, imagistic and expressive character of the music. The knowledge of the musical art laws determines the conformation to the specific to musical activities methodology; contributes to the generation/ development of the art consumer; facilitates the generation/ development of the artistic abilities of the pre-schoolers/ parents; provides the adequate integration of art in the educative act of the pre-schooler; stimulates the interest and positive attitude for art. Under the peculiarities of the musical art laws there are built the methodological suggestions for the early education.
Number 13 / Part I. Music. 4. Promoting Development and Change: Civil Disobedience in The Legal-Political Thinking and The Musical Field
Authors: Marisi Flavia
Published: March 2017

A public, non-violent act not abiding by a recognized rule, and conscientiously done with the intent to frustrate the latter, is called an act of civil disobedience. Those who practice civil disobedience reject a specific rule, considering it unfitting with their own ethical, religious, or artistic values, and are prepared to suffer the indignities which may greet their act. The paper offers a comparative view on civil disobedience in the legalpolitical and the musical field, basing on the conceptualizations by philosophers and legal thinkers as Thoreau, Bedau, Rawls and Dworkin, and briefly analyzing some works by Monteverdi, Mozart and Liszt as examples of civil disobedience.
Number 13 / Part I. Music. 6. Requiem by Karl Jenkins. An Analytical Approach to The Interweaving of Various Traditions in Music
Authors: Iațeșen Loredana Viorica
Published: March 2017

In the diverse space of contemporary music, the fascinating and controversial personality of the Welsh composer Karl Jenkins, which is surprising from several perspectives, stands out. Open to assimilating and processing music from various sources (academic, liturgical, folk, entertainment, oriental, exotic), the all-round musician Karl Jenkins impresses the public with unexpected artistic choices, giving up the hypostasis of instrumentalist of the jazz-rock band Nucleus and of the group Softmachine in favour of the postmodern creator he has become today, synthetizing trends from musical compositions of the last decades of the 20th century. Once with the return to the functional system, either through minimalism or through neo-romanticism, the artist has successfully covered a potential sonority path of modern opposites, also evoking references to creative models of the past. We are referring to the musical valorizing of the sacred in a synthetic vision between tradition and innovation, in the works included in the Adiemus cycle, in the opus choir Missa for Peace and, more particularly, in the Requiem (2005), a significant score in the contemporaneity. The manner in which the composer, while resorting to a musical genre originating from the Roman Catholic cult and drawing on the liturgical text of the Mass for the dead, inserted Japanese poetry, written following the structure of haiku, belonging to representative authors - Gozan Koshigaya, Issho Kosughi, Hokusai Katsushika, Kaga-no-Chiyo, is highly surprising. This study aims to highlight the interweaving imagined by Karl Jenkins between the two cultures as well as to conduct a semantic analysis of an opus in which the relationships between music and words entail a highly emotional response.
