Published: August 2015

Eckerite, ideally Ag2CuAsS3, is a new mineral from the Lengenbach quarry in the Binn Valley, Valais, Switzerland. It occurs as very rare euhedral crystals up to 300 μm across associated with realgar, sinnerite, hatchite, trechmannite and yellow, fibrous smithite. In thick section eckerite is opaque with a metallic lustre and shows a dark orange-red streak. It is brittle; the Vickers hardness (VHN25) is 70 kg/mm2(range: 64–78) (Mohs hardness of ∼2½–3). In reflected light, eckerite is moderately bireflectant and weakly pleochroic from light grey to a slightly bluish grey. Internal reflections are absent. Under crossed nicols, it is weakly anisotropic with greyish to light blue rotation tints. Reflectance percentages forRminandRmaxare 27.6, 31.7 (471.1 nm), 22.8, 26.1 (548.3 nm), 21.5, 24.5 (586.6 nm) and 19.4, 22.3 (652.3 nm), respectively.

Eckerite is monoclinic, space groupC2/c, witha= 11.8643(3),b= 6.2338(1),c= 16.6785(4) Å, β = 110.842(3)°,V= 1152.81(5) Å3,Z= 8. The crystal structure [R1= 0.0769 for 1606 reflections withFo> 4σ(Fo)] is topologically identical to that of xanthoconite and pyrostilpnite. In the structure, AsS3 pyramids are joined by AgS3triangles to form double sheets parallel to (001); the sheets are linked by Cu(Ag) atoms in a quasi-tetrahedral coordination. Among the three metals sites, Ag2 is dominated by Cu. The mean metal–S distances reflect well the Ag ↔ Cu substitution occurring at this site.

The eight strongest powder X-ray diffraction lines [din Å (I/I0) (hkl)] are: 3.336 (70) (312); 2.941 (100) (314,114); 2.776 (80) (400,206); 2.677 (40) (312); 2.134 (50) (421); 2.084 (40) (208,206); 2.076 (40) (420); 1.738 (40) (228,226). A mean of five electron microprobe analyses gave Ag 52.08(16), Cu 11.18(9), Pb 0.04(1), Sb 0.29(3), As 15.28(11), S 20.73(13), total 99.60 wt.%, corresponding, on the basis of a total of 7 atoms per formula unit, to Ag2.24Cu0.82As0.94Sb0.01S2.99. The new mineral has been approved by the International Mineralogical Association Commission on New Minerals, Nomenclature and Classification (2014–063) and named for Markus Ecker, a well known mineral expert on the Lengenbach minerals for more than 25 years.
First crystal-structure determination of chromites from an acapulcoite and ordinary chondrites
Authors: Lenaz Davide , Princivalle Francesco , Schmitz Birger
Published: August 2015

We report the first crystal-structure determinations of chromites from an acapulcoite and from ordinary chondrites. Cell edges range from 8.3212 (3) to 8.3501 (1) Å, while the oxygen positional parameters are in the range 0.2624 (3) to 0.26298 (9). Their compositions show they are very close to the chromite end-member FeCr2O4 with limited Al and Mg content. Titanium oxide content exceeds 1 wt.%, whereas the amount of Fe3+ is negligible. Extraterrestrial chromite is distinguished readily from terrestrial analogues on the basis of the cell edge and oxygen positional parameter. These distinctions will facilitate ongoing attempts to reconstruct the palaeoflux of meteorites to Earth from resistant extraterrestrial spinel grains recovered from ancient sediments.

Published: August 2015

Despite multimodal regimens and diverse treatment options alleviating disease symptoms, morbidity and mortality associated with advanced ischemic heart failure remain high. Recently, technological innovation has led to the development of regenerative therapeutic interventions aimed at halting or reversing the vicious cycle of heart failure progression. Driven by the unmet patient need and fueled by encouraging experimental studies, stem cell-based clinical trials have been launched over the past decade. Collectively, these trials have enrolled several thousand patients and demonstrated the clinical feasibility and safety of cell-based interventions. However, the totality of evidence supporting their efficacy in ischemic heart failure remains limited. Experience from the early randomized stem cell clinical trials underscores the key points in trial design ranging from adequate hypothesis formulation to selection of the optimal patient population, cell type and delivery route. Importantly, to translate the unprecedented promise of regenerative biotherapies into clinical benefit, it is crucial to ensure the appropriate choice of endpoints along the regulatory path. Accordingly, we here provide considerations relevant to the choice of endpoints for regenerative clinical trials in the ischemic heart failure setting.

Introduction

Zellweger spectrum disorder (PBD-ZSD) is a disease continuum caused by mutations in a subset ofPEXgenes required for normal peroxisome assembly and function. They highlight the importance of peroxisomes in the development and functions of the central nervous system, liver, and other organs. To date, the underlying bases for the cell-type specificity of disease are not fully elucidated.

Methods

Primary skin fibroblasts from seven PBD-ZSD patients with biallelicPEX1,PEX10,PEX12, orPEX26mutations and three healthy donors were transduced with retroviral vectors expressing Yamanaka reprogramming factors. Candidate induced pluripotent stem cells (iPSCs) were subject to global gene expression, DNA methylation, copy number variation, genotyping, in vitro differentiation and teratoma formation assays. Confirmed iPSCs were differentiated into neural progenitor cells (NPCs), neurons, oligodendrocyte precursor cells (OPCs), and hepatocyte-like cell cultures with peroxisome assembly evaluated by microscopy. Saturated very long chain fatty acid (sVLCFA) and plasmalogen levels were determined in primary fibroblasts and their derivatives.

Results

iPSCs were derived from seven PBD-ZSD patient-derived fibroblasts with mild to severe peroxisome assembly defects. Although patient and control skin fibroblasts had similar gene expression profiles, genes related to mitochondrial functions and organelle cross-talk were differentially expressed among corresponding iPSCs. Mitochondrial DNA levels were consistent among patient and control fibroblasts, but varied among all iPSCs. Relative to matching controls, sVLCFA levels were elevated in patient-derived fibroblasts, reduced in patient-derived iPSCs, and not significantly different in patient-derived NPCs. All cell types derived from donors with biallelic null mutations in aPEXgene showed plasmalogen deficiencies. Reporter gene assays compatible with high content screening (HCS) indicated patient-derived OPC and hepatocyte-like cell cultures had impaired peroxisome assembly.

Conclusions

Normal peroxisome activity levels are not required for cellular reprogramming of skin fibroblasts. Patient iPSC gene expression profiles were consistent with hypotheses highlighting the role of altered mitochondrial activities and organelle cross-talk in PBD-ZSD pathogenesis. sVLCFA abnormalities dramatically differed among patient cell types, similar to observations made in iPSC models of X-linked adrenoleukodystrophy. We propose that iPSCs could assist investigations into the cell type-specificity of peroxisomal activities, toxicology studies, and in HCS for targeted therapies for peroxisome-related disorders.
Improving seismic resolution of prestack time-migrated data
Authors: Mutlu Onur , Marfurt Kurt J.
Published: August 2015

Seismic resolution significantly affects the quality of seismic interpretation. Processing parameters that effect resolution such as picking velocities in the presence of interbed multiples benefit from an understanding of the underlying geology. Three-dimensional migration is almost always performed by an external service company or internal specialty processing group, with the “final” product being migrated gathers and the final migration-stack section. In the Chicontepec Basin, Mexico, we have evaluated improvements in data quality made after 3D prestack time migration. By first mapping shallow volcanics that generated strong interbed multiples, we performed a new velocity analysis to better image the weaker, underlying primaries of interest. We remove the local migration stretch through an inverse NMO correction, followed by a nonstretch NMO correction and prestack structure-oriented filtering. Such compensation for migration stretch improves the vertical resolution and preserves far-offset data valuable to subsequent prestack inversion that would otherwise need to be muted. Because S-impedance inversion depends heavily on the farther offsets, the resulting S-impedance images have resolution that is in general equivalent to and, in the target area of rapid S-impedance seen in the well logs, exceed that of the P-impedance images. Attributes such as coherence and curvature show improved fault resolution, whereas noisy areas look more chaotic because of the increased frequency content.
HLA Markers DQ8 and DR53 Are Associated With Lymphocytic Hypophysitis and May Aid in Differential Diagnosis
Authors: Heaney Anthony P. , Sumerel Brittany , Rajalingam Raja , Bergsneider Marvin , Yong William H. , Liau Linda M.
Published: August 2015

Importance:

Lymphocytic hypophysitis (LH) is a poorly understood autoimmune disorder of the pituitary gland. Symptoms include headache, pituitary dysfunction, visual disturbances, and neurological deficits. The diagnosis can be made based on clinical and biochemical findings, but for atypical presentations, no circulatory diagnostic biomarkers exist, and a pituitary biopsy is necessary for diagnosis.

Objectives:

We used high-resolution human leukocyte antigen (HLA) screening assays to investigate a relationship between specific HLA markers and LH.

Design:

This was a retrospective analysis.

Setting:

The study was conducted at a tertiary referral center.

Subjects:

Fifteen patients with sporadic LH, 4 patients with melanoma who developed hypophysitis after administration of cytotoxic T lymphocyte antigen 4 (CTLA4) antibodies, and 1 patient with sarcoid-associated hypophysitis were evaluated.

Intervention:

Clinical data, including endocrine function, were assessed, and HLA typing was performed in all 20 patients with hypophysitis, 50 control patients with other sellar abnormalities, and 4 CTLA4 antibody–treated patients without hypophysitis.

Results:

Two major histocompatibility class II HLA markers, DQ8 and DR53, were found in 13 of 15 (87%) and 12 of 15 (80.0%) patients with sporadic LH, respectively. In contrast, none of the 4 patients who developed hypophysitis after administration of the CTLA4 antibodies exhibited the HLA-DQ8 marker and only 1 of 4 (25%) exhibited the HLA-DR53 marker. In a parallel group of 50 control subjects with sellar masses and 4 CTLA4 antibody–treated patients who did not develop evidence of pituitary failure, the candidate HLA subtypes were found in ∼20% for DQ8 and ∼48% for DR53, respectively.

Conclusion and Relevance:

The HLA markers, DQ8 and DR53, were found to be commonly present in patients with LH. The odds ratio of a patient with LH expressing the HLA-DQ8 marker is 23.1-fold higher than that of a patient with another sellar mass. HLA-DQ8 testing may assist in diagnosis and avoid unnecessary biopsies in patients with atypical LH.
Lewis Acid-catalyzed Ring-opening Addition Reactions of Alcohols to Vinylcyclopropane
Authors: Matsuoka Shin-ichi , Numata Kazuki , Suzuki Masato
Published: August 2015

Lewis acids such as Sn(OTf)2, GaCl3, Sc(OTf)3, and Al(OTf)3 catalyzed ring-opening 1,5-addition reactions of aliphatic alcohols to dimethyl 2-vinylcyclopropane-1,1-dicarboxylate, resulting in moderate to high yields of methyl 4-alkoxy-2-methoxycarbonyl-5-hexenoates with a catalytic turnover number of up to 80. A deuterium-labeling experiment and comparison with the reactivity of dimethyl cyclopropane-1,1-dicarboxylate suggested that this reaction involves a 1,3-dipole intermediate stabilized by the donor and the acceptor substituents. The ring-opening addition of phenols demonstrated several reaction modes, including Friedel–Crafts 1,5- and 1,7-additions.

Time and image of Phaedra in the works “Hippolytus” by euripides, “Phaedra” by Jean Racine and in the lyrics by Marina Tsvetaeva
Authors: Иванова Ирина , Ivanova Irina
Published: August 2015

The article tells about the transformation of a wandering ancient story about the passion of a mother to her stepson, shows how each era brings about changes in the depiction of the heroine, set in a boundary situation between happiness and duty. In the tragedy of Euripides "Hippolytus" the main character is the king´s son, and Phaedra is a performer of the will of the goddess Cypris. Without knowing, Hippolytus violated ethics law that prescribed to honor equally all the gods and goddesses: he loved to worship the goddess of the hunt Artemis and didn´t bring enough victims to Aphrodite. According to the mythological sources, the election of Phaedra as the instrument of revenge can be explained by the fact that Phaedra carries the burden of a tragic guilt for her grandfather, who told Hephaestus about the affair between Aphrodite and Ares. Euripides describes the suffering of Phaedra. His character brings her life as a gift to the children. The tragedy of the debt victory is displayed brighter by the Greek author than by the French one. But the image of Phaedra, made by Jean Racine, is nobler than it was made by Euripides. The heroine of Euripides sacrifices herself for the sake of duty and commits suicide, but makes a low act, leaving a note that slanders Hippolytus, but the queen by Racine, dying, emphasizes the innocence of her stepson. The stepson´s attitude to the passion of his stepmother changes too. For Hippolytus by Euripides the passion of Phaedra is the evidence of low-lying nature of women, for Hippolytus by Jean Racine it is the touching continuation of conjugal love at first, and then, when Phaedra separates him in her mind from the father, and emphasizes that loves Hippolytus, it is a horrible discover, but not the reason for the generalization, reasoning and discrimination against all women. The continuation of the incarnation of vagrant story about Phaedra we see in the poetry of Marina Tsvetaeva in the tragedy "Phaedra". Tsvetaeva simplifies antique tragedy, removing the problem of choosing between happiness and duty, but in the poem she returns to the tragic beginning of it, highlighting the theme of the sublime punishments with passion that is emphasized in the interpretation ofR. Viktyuk, who created a cinema play "Passion about Phaedra in four dreams of Roman Viktyuk" on the basis ofTsvetayeva´s texts.

Published: August 2015

A forma dos agregados minerais afeta várias propriedades das misturas asfálticas, dentre elas a resistência à de-formação permanente e à fadiga. A forma está diretamente relacionada com as proporções geométricas dos agregados. Vários são os métodos laboratoriais utilizados para determinar a forma dos agregados, mas frequentemente eles são trabalhosos e, por vezes, subjetivos. Neste trabalho, é apresentado o método de esqueletização multiescala para determinação das caracte-rísticas de forma dos agregados. Este método é simples de ser executado, e os resultados são de fácil entendimento. Neste método, as partículas são reduzidas a uma estrutura mais simples, chamada de esqueleto, em diferentes níveis de detalhamento (limiares). Dois tipos de agregados foram utilizados, basalto e seixo, com graus de esfericidade de 0,77 e 0,87, respectiva-mente, segundo a tabela Rittenhouse. As imagens dos agregados foram obtidas através de um scanner. Os esqueletos das imagens dos agregados foram obtidos utilizando a transformada distância, e os modelos de classificação foram obtidos a partir dos esqueletos por meio dos descritores de forma: raios médios, variância, número de ramos, tamanho do maior ramo e esfericidade. O melhor nível de detalhamento do esqueleto foi obtido empregando o valor de limiar igual a 5. O modelo de classificação apresentou 97% de acurácia quando empregado utilizando o algoritmo IBk. Este elevado índice de acerto de-monstra a robustez do método de esqueletização para a determinação e a classificação dos agregados quanto à forma.

Neste artigo é aplicada a metaheurística Guided Local Search (GLS) para resolver o Problema de Programação de Tripulações de Ônibus Urbano (PPT). O PPT consiste em encontrar um conjunto de jornadas a serem designadas aos motoristas que realizarão a operação diária com o menor custo. A GLS tem como princípio penalizar características indesejáveis presentes na solução corrente, com o objetivo de escapar de soluções ótimas locais. Como heurística de busca local, foi utilizada a heurística Variable Neighborhood Descent, que explora diferentes estruturas de vizinhança para encontrar um mínimo local. De acordo com pesquisa realizada pelos autores, esta abordagem é inédita para resolver o PPT. A implementação proposta foi testada com dados de problemas reais de uma empresa que opera em uma região metropolitana de Belo Horizonte. Os resultados obtidos são similares àqueles presentes na literatura, havendo possibilidades de melhorias, visto que a GLS pode ser explorada em diferentes aspectos.
Warum wir das Konzept des gerechten Krieges brauchen. Erwägungen aus römisch-katholischer Perspektive
Authors: Stobbe Heinz-Günther
Published: August 2015

This contribution first sketches the problem (of why the concept of ›just war‹ is still indispensable) by contrasting two positions representing the pros and cons of the just war doctrine. It also presents some reasons that forbid a seamless continuation of this doctrine. In a second step, the development of catholic doctrine is shown exemplified by three episcopal letters, which argue in favour of the right of self-defense and the criteria of just war as indispensable core values of the tradition and towards an integration of both within the concept of humanitarian intervention. Final considerations supplement this perspective by hinting to the inevitable tension between law and justice as well as legality and legitimacy within the context of the debate on the concept of international Responsibility to Protect.

Florid cemento-osseous dysplasia (FCOD) is a rare distinguishable condition that characteristically affects the jaws of middle aged women. It is usually symmetrical on both sides and manifests radiographically as diffuse, lobulated multiple sclerotic radio-opacities involving all the quadrants of the jaws. The lesion is mostly benign and requires no treatment unless the patient is symptomatic. For the asymptomatic patient the best management advisable is regular recall checkups and reinforcement of good oral hygiene. Herewith, we are reporting one such rare entity of a 37 year old female patient.

Fractional differentiation of the product of Bessel functions of the first kind
Authors: Sebastian Nicy , Gorenflo Rudolf
Published: August 2015

Two differential transforms involving the Gauss hypergeometric function in the kernels are considered. They generalize the classical Riemann–Liouville and Erdélyi–Kober fractional differential operators. Formulas of compositions for such generalized fractional differentials with the product of Bessel functions of the first kind are proved. Special cases of products of cosine and sine functions are given. The results are established in
terms of a generalized Lauricella function due to Srivastava and Daoust. Corresponding assertions for the Riemann–Liouville and the Erdélyi–Kober fractional integral transforms are presented. Statistical interpretations of fractional-order integrals and derivatives are also established.

Published: August 2015

In this paper, we model the mortality rate in Thailand by using the Lee-Carter model. Three classical methods, i.e. Singular Value Decomposition (SVD), Weighted Least Square (WLS), and Maximum Likelihood Estimation (MLE) are used to estimate the parameters of the Lee-Carter model. With these methods, we investigate the goodness of fit for the mortality rate spanning the period 2003 to 2012. The fitted models are compared. The autoregressive moving average (ARIMA) is used to forecast the general index and mortality rate the time period from 2013 to 2022. As a result, we also forecast Thai life expectancy at birth.

Flora and Vegetation of the Island of Kalamos (Ionian Sea, Greece) – Floristic Analysis and Phytogeographical Aspects
Authors: Baliousis Evagelos
Published: August 2015

The floristic investigation of the Ionian island of Kalamos resulted in the addition of 275 specific and infraspecific taxa, which are reported here, to a present total of 502 taxa. For each newly recorded taxon local distribution and habitat types are presented. Convolvulus pentapetaloides and Malcolmia graeca subsp. hydraea are reported for the first time from the Ionian islands. Some of the new records concern rare taxa in Greece or regional endemics, which are, therefore, chorologically significant, such as Alkanna corcyrensis, Stachys ionica, Heptaptera colladonioides. A brief description of some of the vegetation types of the island is given. The results of floristic analysis and phytogeographical aspects demonstrate the pronounced Mediterranean character of the island’s flora.

The paper presents validations of some syntaxon names of the saline vegetation of Eastern Europe (southern Russia and Kazakhstan), namely of the Carici dilutae-Juncion gerardii, Anabasio salsae-Artemision pauciflorae, Carici dilutae-Juncetum gerardii. The names of the Suaedion acuminatae, Climacoptero crassae-Suaedion acuminatae and the Suaedetum acuminatae are corrected because of erroneous selection of eponymous taxon names. We also suggest that the ‘Tamariceto-Salsolion australis’ nom. illeg. should be a synonym of the Euphorbion sequieranae.
A New Method to Produce Ni–Cr Ferroalloy Used for Stainless Steel Production
Authors: Chen Pei-Xian , Chu Shao-Jun , Zhang Guo-Hua
Published: August 2015

A new electrosilicothermic method has been proposed in the present paper to produce Ni–Cr ferroalloy, which can be used for the production of 300 series stainless steel. Based on this new process, the Ni–Si ferroalloy is first produced as the intermediate alloy, and then the desiliconization process of Ni–Si ferroalloy melt with chromium concentrate is carried out to generate Ni–Cr ferroalloy. The silicon content in the Ni–Si ferroalloy produced in the submerged arc furnace should be more than 15 mass% (for the propose of reducing dephosphorization), in order to make sure the phosphorus content in the subsequently produced Ni–Cr ferroalloy is less than 0.03 mass%. A high utilization ratio of Si and a high recovery ratio of Cr can be obtained after the desiliconization reaction between Ni–Si ferroalloy and chromium concentrate in the electric arc furnace (EAF)–shaking ladle (SL) process.
Effects of interval training-based glycolytic capacity on physical fitness in recreational long-distance runners
Authors: Zatoń Marek , Michalik Kamil
Published: August 2015

Purpose

The aim of this study was to investigate the influence of 8-week-long interval training (targeting glycolytic capacity) on selected markers of physical fitness in amateur long-distance runners.

Methods

The study involved 17 amateur long-distance runners randomly divided into an experimental (n = 8) and control (n = 9) group. The control group performed three or four continuous training sessions per week whereas the experimental group performed two interval running training sessions and one continuous running training session. A graded treadmill exercise test and the 12-min Cooper test were performed pre- and post-training.

Results

VO2max and the rate of recovery increased in the experimental group. Relative oxygen uptake, minute ventilation, and heart rate speed decreased in low- (6 km/h) and medium-intensity (12 km/h) running.

Conclusions

Both training modalities showed similar results. However, the significant differences in training volume (4–8 min interval training vs. 40–150 min continuous training) indicates that the modalities targeting glycolytic capacity may be more efficient for amateur runners prepare for long-distance events.

Authors: Gonçalves Eder , Gonzaga Adeilton Dos Santos , Cardoso Felippe da Silva Leite , Teoldo Israel
Published: August 2015

Purpose

The present study aimed to examine the current methods employed to assess anticipation in soccer players as well as to elicit the main findings of recent studies.

Methods

The study was carried out in systematic review form and its sample comprised nine scientific papers published in academic journals. Only the studies involving soccer players (professionals and amateurs, except goalkeepers) were included in this review.

Results and conclusions

We observed that most of the studies employed video footage obtained from soccer matches, which are occluded at a given point for study participants to quickly and precisely elicit the positions of opponents, teammates and the ball as well as anticipate actions (dribbling, shooting, passing) from surrounding players (teammates and opponents). In addition, the studies compared the performance of players from both high and low competitive levels in anticipation tasks.
Jumping abilities and power-velocity relationship in judo athletes: Comparative analysis among age categories
Authors: Buśko Krzysztof
Published: August 2015

Purpose

The aim of the study was to examine age differences in the maximal power and height of rise of the body mass centre measured in spike jump (SPJ) and counter-movement jump (CMJ), and power-velocity relationship of lower extremities between cadet and U23 age class judo athletes.

Methods

Seven cadets (age 16.6 ± 0.7 years) and eight U23 age class (21.3 ± 1.4 years) Polish judoists took part in the study. The maximal power and height of jump were measured at SPJ and CMJ jumps. Power–velocity relations (P–v) were determined from 5 maximal cycle ergometer exercise bouts at increasing external loads equal to 2.5, 5.0, 7.5, 10.0 and 12.5% of body weight (BW).

Results

Cadet judoists had a significantly smaller maximal power output (11.56 ± 1.21 W • kg–1) than U23 athletes (12.69 ± 0.67 W • kg–1). The optimal velocity was similar in both group (119.3 ± 16.0 rpm and 119.6 ± 15.5 rpm, respectively). Significant age differences were founded between the cadet and U23 athletes for power output at external load equal 12.5% BW. Cadet judoists generated insignificantly lower maximal power in CMJ and SPJ than U23 judo athletes with except of the absolute maximal power in SPJ. The age difference was observed in height of CMJ.

Conclusions

Based on the characteristics of F–v curve we can see in which direction follow the effects of training. Application of CMJ and SPJ in jumping test allows to assess changes in neuromuscular coordination. The use of the both methods give better information to optimal training control.

Published: August 2015

Osmotic dehydration offers an alternative to air-drying for reducing moisture content at ambient temperature. Of four different solutes investigated, 22% (mass basis) sodium chloride (NaCl) and 60% (mass basis) sucrose solutions were the most successful, with each achieving approximately a 10% reduction in wet basis moisture content after 8 h without significant detrimental side effects, although NaCl solutions cause noticeable darkening in the pits on the surface of the chestnuts. The presence of the shell and pellicle did not significantly affect the dehydration rate. Osmotic dehydration by NaCl or sucrose prior to mechanical shell removal produced a small increase in efficiency of the shell removal process.

Published: August 2015

Variable diffusivity and volume of the grains are taken into account in the diffusion model that describes mass transfer in soybean hydration. The variable space grid method (VSGM) was used to consider the increase in grain size, and the diffusivity was considered an exponential function of the moisture content. An equation for the behavior of the grain radius as a function of time was obtained by global mass balance over the soybean grain and the differential equation considered that the increase in radius happens due to the influence of the convective and diffusive fluxes at the surface of the grains. The model was solved by an explicit numerical scheme which presented satisfactory results. The results showed the behavior of moisture profiles obtained as a function of time and radial position and also showed how the grain radius increased with time and changed the solution domain of the diffusion equation.

‘The vsuall speach of the Court’? Investigating language change in the Tudor family network (1544–1556)
Authors: Evans Mel
Published: August 2015

This paper considers how micro-level analysis can enrich our understanding of macro-level processes of language change, using a case study of the Tudors. It explores how language use in the Tudor family network relates to the role of the Court in the supralocalisation of innovative forms during the sixteenth century. Using an original corpus of correspondence and other autograph writings, I conduct a comparative analysis of the language of Elizabeth Tudor with her siblings, parents and caregivers. The findings suggest that Elizabeth’s siblings, Mary I and Edward VI, were progressive in changes localised at the Court, but that Elizabeth’s caregivers and peripheral kin may have influenced Elizabeth’s uptake of non-Court-based changes. Using Network Strength Scores to represent the social experiences of Elizabeth and her nearest kin, it appears that Elizabeth’s changing position within the Court network, from a peripheral to more central member, may have played a part in the Court’s catalyst effect for the supralocalisation of innovative forms, and the emergence of an overtly prestigious “norm” in Early Modern English.
Language shift and apparent standardisation in Early Modern English
Authors: Knooihuizen Remco
Published: August 2015

It has been observed that language-shift varieties of English tend to be relatively close to Standard English (Trudgill and Chambers 1991: 2–3). An often-used explanation for this is that Standard English was acquired in schools by the shifting population (Filppula 2006: 516). In this paper, I discuss three cases of language shift in the Early Modern period: in Cornwall, the Isle of Man, and Shetland. I offer evidence that the role of Standard English education was, in fact, fairly limited, and suggest that the standard-likeness of Cornish English, Manx English and Shetland Scots is most likely due to the particular sociolinguistic circumstances of language shift, where not only language contact, but also dialect contact contributed to a loss of non-standard-like features and the acquisition of a standard-like target variety. This atelic and non-hierarchical process is termedapparent standardisation.
Power Individuation: A New Version of the Single-Tracking View
Authors: Głowala Michał
Published: August 2015

The paper answers three questions concerning power individuation: Can one power have various manifestations? If so, do they have to be unified in some way? If so, how exactly do they have to be unified? After a review of contemporary standpoints (Molnar, Lowe, Williams) I present a version of single-tracking view (inspired by Aquinas’s views on the individuation of powers) which is significantly different from contemporary single-tracking proposals of Molnar and Lowe. The main idea is that different sorts of powers have distinct ways of producing their manifestations, so a pair of different manifestations may require distinct powers of one kind, but just one and the same power of another kind. This suggests the form of the unifying description specific for powers. I argue (taking into account some alleged counterexamples) that all the manifestations of one power of some kind must fall under this sort of unifying description.
Ionization Impact on the Air Cleaning Efficiency in the Interior

Published: August 2015

The paper deals with ionization impact on efficient cleaning of air in a measuring chamber which has been cleaned and closed against any outer impacts (e.g. impurities, dust from another room, human odours). Smoking has an impact on the number of positive and negative ions including the concentration of particulate matter PM10. We investigated the ion concentration according to the presence of cigarette smoke in the room and according to the change of lit cigarette distance from the supply of ionized air. Due to the experiment there was simulated smoking at the relative air humidity φ = 37 % and φ = 39 % and temperature of 20 °C in the room. Increased PM10 concentrations were caused only by cigarette smoke pollution or more precisely by artificially created higher humidity in the measuring room excluding ambient environment impacts. The aim of the experiments was to prove influence of ionization on the elimination of cigarette smoke. The measurements showed that the highest efficiency of PM10 particulate removal was achieved when the distance of smoking cigarettes from ionization source was 3 m and the air humidity was 39 %. The consequent increase of the distance of smoking cigarettes from the ionization source significantly decreased the efficiency of particle removal. The difference between ionized and natural air is minimal at the bigger distance.
Comparison of the Effects of Cross-validation Methods on Determining Performances of Classifiers Used in Diagnosing Congestive Heart Failure
Authors: Isler Yalcin , Narin Ali , Ozer Mahmut
Published: August 2015

Congestive heart failure (CHF) occurs when the heart is unable to provide sufficient pump action to maintain blood flow to meet the needs of the body. Early diagnosis is important since the mortality rate of the patients with CHF is very high. There are different validation methods to measure performances of classifier algorithms designed for this purpose. In this study, k-fold and leave-one-out cross-validation methods were tested for performance measures of five distinct classifiers in the diagnosis of the patients with CHF. Each algorithm was run 100 times and the average and the standard deviation of classifier performances were recorded. As a result, it was observed that average performance was enhanced and the variability of performances was decreased when the number of data sections used in the cross-validation method was increased.
GPU-Accelerated Reconstruction of T2 Maps in Magnetic Resonance Imaging
Authors: Mikulka Jan
Published: August 2015

The main tissue parameters targeted by MR tomography include, among others, relaxation times T1 and T2. This paper focuses on the computation of the relaxation time T2 measured with the Spin Echo method, where the sensing coil of the tomograph provides a multi-echo signal. The maxima of these echoes must be interleaved with an exponential function, and the T2 relaxation can be determined directly from the exponential waveform. As this procedure needs to be repeated for each pixel of the scanned tissue, the processing of large images then becomes very intensive. For example, given the common resolution of 256×256 with 20 slices and five echoes at different times TE, it is necessary to reconstruct 1.3∙106 exponential functions. At present, such computation performed on a regular PC may last even several minutes. This paper introduces the results provided by accelerated computation based on parallelization and carried out with a graphics card. By using the simple method of linear regression, we obtain a processing time of less than 36 ms. Another effective option consists in the Levenberg-Marquardt algorithm, which enables us to reconstruct the same image in 96 ms. This period is at least 900 times shorter than that achievable with professional software. In this context, the paper also comprises an analysis of the results provided by the above-discussed techniques.
Analysis of Spectral Features of EEG signal in Brain Tumor Condition
Authors: Selvam V. Salai , Devi S. Shenbaga
Published: August 2015

The scalp electroencephalography (EEG) signal is an important clinical tool for the diagnosis of several brain disorders. The objective of the presented work is to analyze the feasibility of the spectral features extracted from the scalp EEG signals in detecting brain tumors. A set of 16 candidate features from frequency domain is considered. The significance on the mean values of these features between 100 brain tumor patients and 102 normal subjects is statistically evaluated. Nine of the candidate features significantly discriminate the brain tumor case from the normal one. The results encourage the use of (quantitative) scalp EEG for the diagnosis of brain tumors
The Politics between the Justice and Development Party (AKP) and the Gülen Movement in Turkey: Issues of Human Rights and Rising Authoritarianism
Authors: Muedini Fait
Published: August 2015

I examine the rising tension between two Islamic movements in Turkey: The Justice and Development Party (AKP) and Fethullah Gülen’s Hizmet Movement within the context of increased human rights abuses by the government in Turkey. I argue that Gülen and Hizmet are a continued concern for Recep Tayyip Erdogan and AKP because of Hizmet’s social services, primarily in the realm of education. Furthermore, their influence in public ranks further troubles Erdogan. However, it seems that because of Hizmet’s disinterest with electoral politics, along with an absence of other challengers to the ruling government party’s electoral success, Erdogan and the AKP will continue to hold political power, at least for the short term. Furthermore, this case illustrates Erdogan’s willingness to carry out increased authoritarian actions, as well as a willingness to violate the human rights of civil society actors in Turkey.
Ultrafast carrier dynamics in Landau-quantized graphene
Authors: Wendler Florian , Knorr Andreas , Malic Ermin
Published: August 2015

In an external magnetic field, the energy of massless charge carriers in graphene
is quantized into non-equidistant degenerate Landau levels including a
zero-energy level. This extraordinary electronic dispersion gives rise to a
fundamentally new dynamics of optically excited carriers. Here, we review the
state of the art of the relaxation dynamics in Landau-quantized graphene
focusing on microscopic insights into possible many-particle relaxation
channels.We investigate optical excitation into a non equilibrium distribution
followed by ultrafast carrier- carrier and carrier-phonon scattering processes.
We reveal that surprisingly the Auger scattering dominates the relaxation
dynamics in spite of the non-equidistant Landau quantization in graphene.
Furthermore, we demonstrate how technologically relevant carrier multiplication
can be achieved and discuss the possibility of optical gain in Landau-quantized
graphene. The provided microscopic view on elementary many-particle processes
can guide future experimental studies aiming at the design of novel
graphene-based optoelectronic devices, such as highly efficient photodetectors,
solar cells, and spectrally broad Landau level lasers.
