A case of chronic ulcer due to subcutaneous arteriolosclerosis in an obese patient mimicking pyoderma gangrenosum
Authors: Fıçıcıoğlu Sezin , Can Nuray , Tutuğ Busem
Published: July 2018

The differential diagnosis of chronic ulcers covers a wide range of diseases and poses a diagnostic challenge. Subcutaneous ischemic arteriolosclerosis can lead to local ischaemia and ulceration as a result of arteriolar narrowing and reduction of tissue perfusion. This pathophysiological feature can be seen in eutrophication (nonuremic calciphylaxis) in morbid obesity, hypertensive ischemic leg ulcer (Martorell ulcer) and calciphylaxis in chronic renal insufficiency. All of the ulcers happened in this way can be wrongly diagnosed as pyoderma gangrenosum because of clinical similarity and inadequate biopsies. We report a case of chronic ulcer due to subcutaneous arteriolosclerosis in morbid obesity, wrongly diagnosed as pyoderma gangrenosum. It can be detrimental to misdiagnose the ulcers due to subcutaneous arteriolosclerosis as pyoderma gangrenosum since they need a diametrically different approach.

Published: July 2018

Since 2007, Naturally Occurring Radioactive Materials (NORM) such as uranium-238 and radon-222 etc. in groundwater from the Community Water-supply Systems (CWS) in two islands have been studied in South Korea. In 71 samples from Ganghwa (G) Island, the maximum value of uranium-238 concentration is 72.21 μg/L. 3 CWSs (4.2%) exceeded the Maximum Contaminant Level (MCL) of 30 μg/L for uranium-238. The maximum value of radon-222 activity is 614 Bq/L. 28 CWSs (39.4 %) did not meet the United States Environment Protection Agency (US EPA) proposed Alternative Maximum Contaminant Level (AMCL) of 148 Bq/L for radon-222. At all CWS that did not meet the US EPA’s MCL or AMCL, some appropriate actions were taken such as water treatment, alternative well development, mixing water of different origins, and so forth. In the 52 CWSs of Jeju (J) Island, the maximum value of uranium-238 and radon-222 concentrations are 1.37 μg/L and 94.83 Bq/L, respectively. All values for uranium-238, gross alpha, and radon-222 meet MCL and proposed AMCL of US EPA drinking water standard. The two islands have different geological settings that are believed to be the causes of the big differences in the NORM levels. Geologically an old island has much higher NORM values than a young island formed in the Quaternary Period due to hydrogeological factors such as recharge and infiltration rates of precipitation. The residence times in the aquifers for water-rock (mineral) interactions are very different from each other.
Modular curvature for toric noncommutative manifolds
Authors: Liu Yang
Published: July 2018

In this paper, we extend recent results on the modular geometry on noncommutative two tori to a larger class of noncommutative manifolds: toric noncommutative manifolds. We first develop a pseudo differential calculus which is suitable for spectral geometry on toric noncommutative manifolds. As the main application, we derive a general expression for the modular curvature with respect to a conformal change of metric on toric noncommutative manifolds. By specializing our results to the noncommutative two and four tori, we recovered the modular curvature functions found in the previous works. An important technical aspect of the computation is that it is free of computer assistance
A categorical perspective on the Atiyah–Segal completion theorem in KK-theory
Authors: Arano Yuki , Kubota Yosuke
Published: July 2018

We investigate the homological ideal

\mathcal J _G^H

, the kernel of the restriction functors in compact Lie group equivariant Kasparov categories. Applying the relative homological algebra developed by Meyer and Nest, we relate the Atiyah–Segal completion theorem with the comparison of

\mathcal J_G^H

with the augmentation ideal of the representation ring.

In relation to it, we study on the Atiyah–Segal completion theorem for groupoid equivariant KK-theory, McClure's restriction map theorem and permanence property of the Baum–Connes conjecture under extensions of groups.

Eight Y chromosome genes show copy number variations in horses

Published: July 2018

Abstract. Copy number variations (CNVs), which represent a significant source of genetic diversity on the Y chromosome in mammals, have been shown to be associated with the development of many complex phenotypes, such as reproduction and male fertility. The occurrence of CNVs has been confirmed on the Y chromosome in horses. However, the copy numbers (CNs) of Equus caballus Y chromosome (ECAY) genes are largely unknown. To demonstrate the copy number variations of Y chromosome genes in horses, the quantitative real-time polymerase chain reaction (qPCR) method was applied to measure the CNVs of the eukaryotic translation initiation factor 1A Y (EIF1AY), equine testis-specific transcript on Y 1 (ETSTY1), equine testis-specific transcript on Y 4 (ETSTY4), equine testis-specific transcript on Y 5 (ETSTY5), equine transcript Y4 (ETY4), ubiquitin activating enzyme Y (UBE1Y), sex determining region Y (SRY), and inverted repeat 2 Y (YIR2) across 14 Chinese domestic horse breeds in this study. Our results revealed that these eight genes were multi-copy; furthermore, some of the well acknowledged single-copy genes such as SRY and EIF1AY were found to be multi-copy in this research. The median copy numbers (MCNs) varied among different breeds for the same gene. The CNVs of Y chromosome genes showed different distribution patterns among Chinese horse breeds, indicating the impact of natural selection on copy numbers. Our results will provide fundamental information for future functional studies.
Transfer entropy and cumulant-based cost as measures of nonlinear causal relationships in space plasmas: applications to Dst
Authors: Johnson Jay R. , Wing Simon , Camporeale Enrico
Published: July 2018

Abstract. It is well known that the magnetospheric response to the solar wind is
nonlinear. Information theoretical tools such as mutual information, transfer
entropy, and cumulant-based analysis are able to characterize the
nonlinearities in the system. Using cumulant-based cost, we show that
nonlinear significance of Dst peaks at 3–12 h lags that can be
attributed to VBs, which also exhibits similar behavior.
However, the nonlinear significance that peaks at lags 25, 50, and 90 h can
be attributed to internal dynamics, which may be related to the relaxation of
the ring current. These peaks are absent in the linear and nonlinear
self-significance of VBs. Our analysis with mutual
information and transfer entropy shows that both methods can establish that
there are strong correlations and transfer of information from
Vsw to Dst at a timescale that is consistent with
that obtained from the cumulant-based analysis. However, mutual information
also shows that there is a strong correlation in the backward direction, from
Dst to Vsw, which is counterintuitive. In contrast,
transfer entropy shows that there is no or little transfer of information
from Dst to Vsw, as expected because it is the solar
wind that drives the magnetosphere, not the other way around. Our case study
demonstrates that these information theoretical tools are quite useful for
space physics studies because these tools can uncover nonlinear dynamics that
cannot be seen with the traditional analyses and models that assume linear
relationships.
Stable isotopes of nitrate reveal different nitrogen processing mechanisms in streams across a land use gradient during wet and dry periods
Authors: Wong Wei Wen , Pottage Jesse , Warry Fiona Y. , Reich Paul , Roberts Keryn L. , Grace Michael R. , Cook Perran L. M.
Published: July 2018

Abstract. Understanding the relationship between land use and the dynamics of nitrate
(NO3-) is the key to constrain sources of NO3-
export in order to aid effective management of waterways. In this study,
isotopic compositions of NO3-
(δ15N–NO3- and
δ18O–NO3-) were used to elucidate the effects of
land use (agriculture in particular) and rainfall on the major sources and
sinks of NO3- within the Western Port catchment, Victoria,
Australia. This study is one of the very few studies carried out in temperate
regions with highly stochastic rainfall patterns, enabling a more
comprehensive understanding of the applications of NO3- isotopes
in catchment ecosystems with different climatic conditions. Longitudinal
samples were collected from five streams with different agriculture land use
intensities on five occasions – three during dry periods and two during wet
periods. At the catchment scale, we observed significant positive
relationships between NO3- concentrations
(p < 0.05), δ15N–NO3-
(p < 0.01) and percentage agriculture (particularly during the
wet period), reflecting the dominance of anthropogenic nitrogen inputs within
the catchment. Different rainfall conditions appeared to be major controls on
the predominance of the sources and transformation processes of
NO3- in our study sites. Artificial fertiliser was the dominant
source of NO3- during the wet periods. In addition to artificial
fertiliser, nitrified organic matter in sediment was also an apparent source
of NO3- to the surface water during the dry periods.
Denitrification was prevalent during the wet periods, while uptake of
NO3- by plants or algae was only observed during the dry periods
in two streams. The outcome of this study suggests that effective reduction
of NO3- load to the streams can only be achieved by prioritising
management strategies based on different rainfall conditions.
Alteration of nitrous oxide emissions from floodplain soils by
aggregate size, litter accumulation and plant
soil interactions
Authors: Ley Martin , Lehmann Moritz F. , Niklaus Pascal A. , Luster Jörg
Published: July 2018

Abstract. Abstract. Semi–terrestrial soils such as floodplain soils are considered potential hotspots of nitrous oxide (N2O) emissions. Microhabitats in the soil, such as within and outside of aggregates, in the detritusphere, and/or in the rhizosphere, are considered to promote and preserve specific redox conditions. Yet, our understanding of the relative effects of such microhabitats and their interactions on N2O production and consumption in soils is still incomplete. Therefore, we assessed the effect of aggregate size, buried organic matter, and rhizosphere processes on the occurrence of enhanced N2O emissions under simulated flooding/drying conditions in a mesocosm experiment. We used two model soils with equivalent structure and texture, comprising macroaggregates (4000–250 µm) or microaggregates (
Automatic detection of calving events from time-lapse imagery at

Published: July 2018

Abstract. Calving is an important process in glacier systems terminating in the ocean and more observations are needed to improve our understanding of the undergoing processes and be able to parameterise calving in larger scale models. Time-lapse cameras are good tools for monitoring calving fronts of glaciers and they have been used widely where conditions are favourable. However, automatic image analysis to detect and calculate the size of calving events has not been developed so far. Here, we present a method that fills this gap using image analysis tools. First, the calving front is segmented. Second, changes between two images are detected and a mask is produced to delimit the calving event. Third, we calculate the area given the front and camera positions as well as camera characteristics. To illustrate our method, we analyse two image time series from two cameras placed at different locations in 2014 and 2015 and compare the automatic detection results to a manual detection. We find a good match when the weather is favorable but the method fails with dense fog or high illumination conditions. Furthermore, results show that calving events are more likely to occur (i) close to where subglacial melt water plumes have been observed to rise at the front and (ii) close to one another.
Isotopic reconnaissance of urban water supply system dynamics
Authors: Jameel Yusuf , Brewer Simon , Fiorella Richard P. , Tipple Brett J. , Terry Shazelle , Bowen Gabriel J.
Published: July 2018

Abstract. Public water supply systems (PWSS) are critical infrastructure that are vulnerable to contamination and physical disruption. Exploring susceptibility of PWSS to such perturbations requires detailed knowledge of supply system structure and operation. The physical structure of the distribution system (i.e., pipeline connections) and basic information on sources are documented for most industrialized metropolises. Yet, most information on PWSS function comes from hydrodynamic models that are seldom validated using observational data. In developing regions, the issue may be exasperated as information regarding the physical structure of the PWSS may be incorrect, incomplete, undocumented, or difficult to obtain in many cities. Here, we present a novel application of stable isotopes in water (SIW) to quantify the contribution of different water sources, identify static and dynamic regions (e.g., regions supplied chiefly by one source vs. those experiencing active mixing between multiple sources), and reconstruct basic flow patterns in a large, complex PWSS. Our analysis, based on a Bayesian mixing model framework, uses basic information on the SIW and production volumes of sources but requires no information on pipeline connections in the system. Our work highlights the ability of SIW to analyze PWSS and document aspects of supply system structure and operation that can otherwise be challenging to observe. This method could allow water managers to document spatiotemporal variation in flow patterns within PWSS, validate hydrodynamic model results, track pathways of contaminant propagation, optimize water supply operation, and help monitor and enforce water rights.
Assessment of a multiresolution snow reanalysis framework: a multidecadal reanalysis case over the upper Yampa River basin, Colorado
Authors: Baldo Elisabeth , Margulis Steven A.
Published: July 2018

Abstract. A multiresolution (MR) approach was successfully implemented in the context
of a data assimilation (DA) framework to efficiently estimate snow water
equivalent (SWE) over a large head water catchment in the Colorado River basin (CRB), while decreasing computational constraints by 60 %. A total of
31 years of fractional snow cover area (fSCA) images derived from Landsat TM,
ETM+, and OLI sensor measurements were assimilated to generate two SWE
reanalysis datasets, a baseline case at a uniform 90 m spatial resolution
and another using the MR approach. A comparison of the two showed negligible
differences in terms of snow accumulation, melt, and timing for the posterior
estimates (in terms of both ensemble median and coefficient of variation).
The MR approach underestimated the baseline peak SWE by less than 2 % and
underestimated day of peak and duration of the accumulation season by a day on average. The
largest differences were, by construct, limited primarily to areas of low
complexity, where shallow snowpacks tend to exist. The MR approach should
allow for more computationally efficient implementations of snow data
assimilation applications over large-scale mountain ranges, with accuracies
similar to those that would be obtained using ∼ 100 m simulations.
Such uniform resolution applications are generally infeasible due to the
computationally expensive nature of ensemble-based DA frameworks.
Mixed layer depth variability in the Red Sea
Authors: Abdulla Cheriyeri P. , Alsaafani Mohammed A. , Alraddadi Turki M. , Albarakati Alaa M.
Published: July 2018

Abstract. For the first time, a monthly climatology of mixed layer depth (MLD) in the Red Sea has been derived based on temperature profiles. The general pattern of MLD variability is clearly visible in the Red Sea, with deep MLDs during winter and shallow MLDs during summer. Transitional MLDs have been found during the spring and fall. The northern end of the Red Sea experienced deeper mixing and a higher MLD associated with the winter cooling of the high-saline surface waters. Further, the region north of 19° N experienced deep mixed layers, regardless of the season. Wind stress plays a major role in the MLD variability of the southern Red Sea, while net heat flux and evaporation are the dominating factors in the central and northern Red Sea regions. Ocean eddies and Tokar Gap winds significantly alter the MLD structure in the Red Sea. The dynamics associated with the Tokar Gap winds leads to a difference of more than 20 m in the average MLD between the north and south of the Tokar axis.

Authors: Cano García Elena , Fernández Ferrer Maite
Published: July 2018

Los estudiantes de origen inmigrante en España aún son un colectivo vulnerable que presenta menor tasas de acceso a la universidad que la población autóctona, básicamente por la precaria situación socioeconómica asociada a su condición de inmigrante. Por ello se han buscado historias de éxito y, a través de relatos de vida, narraciones audiovisuales y cuestionarios abiertos, se han identificado las competencias clave y los factores más relevantes que los estudiantes universitarios hijos/as de familias inmigrantes en Cataluña consideran útiles para llegar a la universidad. Los resultados del estudio apoyan los hallazgos de investigaciones previas puesto que los estudiantes participantes han destacado que los factores más relevantes para éxito son la autoconfianza y auto eficacia, el apoyo de la familia, en especial de las madres y el papel de algún/a profesor/a de secundaria por sus altas expectativas acerca de sus posibilidades. A la vez los resultados ofrecen pistas para diseñar políticas y acciones de apoyo a este colectivo y potenciar su éxito escolar para que accedan a la universidad.
"I pretended to be a boy on the Internet": Navigating affordances and constraints of social networking sites and search engines for LGBTQ+ identity work
Authors: Kitzie Vanessa
Published: July 2018

In this multi-platform study, I analyze interviews with 30 lesbian, gay, bisexual, transgender, and queer (LGBTQ+) individuals in the United States (U.S.) to demonstrate how social networking sites (SNS) and search engines afford and constrain their identity work. Data analysis identifies three key affordances and constraints for how participants create, negotiate, and sustain their LGBTQ+ identities: identity expression, visibility, and anonymity. I explore each using a tripartite analytical frame of stigma, tactics, and authenticity. Findings describe how participants navigate hetero- and gender-normative discourses encoded into SNS and search engines to affirm their LGBTQ+ identities. Designers can use these results to create platforms inclusive of LGBTQ+ identities that afford, rather than constrain, these navigations.
Reading Hamilton Backward: Some Difficulties in Hamilton's Democratic Prescriptions
Authors: Glaser Daryl
Published: July 2018

Hamilton's focus on representation rather than “participatory democracy” is welcome. He has (usefully) highlighted the representational nature of so-called participatory democracy rather than offered putative alternatives to representation. However, his critique of representation deficits in South Africa shows insufficient appreciation of the importance of proportional representation to equal freedom. An examination of the history of council theory and practice on the left provides a basis for some skeptical thoughts about Hamilton's council-tribune model. Although Hamilton's particular institutional prescription is not required by his theory of representation, flaws in the former may be influenced his theorization of group representation.

Statistical Analysis of the Pilling Behaviour of Polyester/Cotton and Polyester/Viscose Blended Woven Fabrics
Authors: Chandrasekaran R. , Periyasamy S. , Shabaridharan K.
Published: July 2018

In this work, the pilling behaviour of polyester blended fabrics was studied and analysed statistically. Two different groups of blends were selected, namely polyester/cotton (P/C) and polyester/viscose blends (P/V). All the fabrics were assessed for pilling performance using ICI pill box, and two-way ANOVA was conducted to analyse the effect of the number of revolutions and type of fibres on the pilling behaviour of the fabrics. The analysis was further narrowed down by conducting a series of ANOVA, by segregating the number of revolutions into two stages and blend proportions into three stages for group I fabrics. Similarly for group II fabrics, both the, number of revolutions and blend proportions were segregated into two stages each. It was found that the type of component fibre used to produce the fabric loses its significance as the number of revolutions increases.
Influence of the Needle Number on the Heat Insulation Performance of Pre-oxidized Fibre Felts
Authors: Zhao Xiaoming , Zhao Xiaoming , Liu Yuanjun , Liu Yuanjun , Liang Tenglong
Published: July 2018

Many factors were needed to be considered to prepare pre-oxidised fibre felts with excellent heat insulation performance, and different production processes showed differences in the heat insulation performance of pre-oxidised fibre felts. In order to probe into the influence of the production process on the heat insulation performance of materials, a large number of experiments were needed to be carried out. For needle-punched nonwoven pre-oxidised fibre felts, web features, needle characteristics and the needle process will all affect the structure of pre-oxidised fibre felts, thus bringing a major influence on the heat insulation performance of pre-oxidised fibre felts. In this paper, the influence of the needle number on the heat insulation performance of pre-oxidised fibre felts was mainly studied. Results showed that an increase in the needle number will cause a decrease in the thickness and gram weight of pre-oxidised fibre felts, and a weakening trend in the heat insulation performance of pre-oxidiaed fibre felts with an increasing needle number at room temperature and at 100-200 °C was shown. Moreover when the needle number was 1 and 2, the pre-oxidised fibre needled felts had good heat insulation performance, and for pre-oxidized fibre felts at different needle numbers with increasing temperature, the temperature difference in a steady state increased linearly.

School is an important element in the reality of a young human. In its space a student spends a large part of his daily life. The school, aware of its importance, is trying to best fulfill this tasks. Particular role is played in the case of a student with a disability, whose functioning is inherently inhibited. Students with intellectual disabilities are based in a very bad position, what is shown in the presented diagnosis.
The diagnosis was carried out in the area of qualitative research the individual case method using an interview technique was applied. The principles of relational diagnosis were referred to.
13-years old Mateusz, a student of fourth grade of elementary integration school, with intellectual disability at light level was interviewed. The research material was enriched with interviews with the boy's mother and his tutor, a Maths teacher.
The students areas of functioning at the school were analyzed in basics: task-based functioning, relations with adults and colleagues and his self image.
The diagnosis shows unfavorable situation of the boy at school. There is disorder in all areas his functioning (according relations between the subject and the adults at the school are relatively most favorable). The boy cannot cope with task situations as a student and friend. Although he attends the integration class he does not feel a full member, his colleague relationships are poor and often disorderly. He does not like to go to school, he cannot cope with study, he has low self-esteem.
The causes of this state should be seen in intellectual disability and unfortunately in school environment deficiencies.
In order to improve the situation, changes are necessary both in the education of students with disabilities, assistance provided to them, as well as in educational support for the social integration of students with disabilities. Without appropriate actions, these students are doomed to school failure, to the threat of social exclusion.
The picture of Youth Prevention Leaders in biographical research
Authors: Rajda Daria
Published: July 2018

The purpose of the article is to present the activities of Youth Prevention Leaders.
The research shown in the article presents activities carried out by youth leaders and also their biographical and personality conditions. The research included 20 prevention leaders who act as part of universal prophylaxis in one of the Upper Silesian cities. A focus interview was applied with the leaders, analysis of the documents and an open interview with the program's supervisor. I show in the article the biographical and personality conditions of the leaders, the reasons for engaging in this activity and features and competences. I also discuss a their benefits, difficulties, successes and needs.
In effect of the conducted research I selected three types of leaders: an activist, a conscious motivator and a goal driven individual getting out of the shadow. The analysis shows that the effects of activities carried out in schools in which youth leaders are present, are definitely better than in schools where they do not work.

Introdução: O Coeficiente de Mortalidade Infantil, indicador das condições sociais e de saúde da população, tem capacidade para orientar a proposição de políticas públicas, instalação e previsão de recursos humanos em saúde. Territórios com elevada mortalidade infantil tendem a ser mais vulneráveis e a necessitarem de uma atenção primária bem estruturada. Objetivo: Mapear a mortalidade infantil e descrever a distribuição geográfica dos serviços e recursos humanos de atenção primária (concentração e “vazios” assistenciais) em Porto Alegre, nos anos 2010 e 2014. Métodos: Estudo descritivo, delineamento ecológico, com emprego de dados secundários disponíveis em sistemas de informações em saúde. O tratamento dos dados ocorreu pelo framework Enyalius. Resultados: Dos 143 serviços, 65% possuem saúde da família, com cobertura de 36,5% da população. Os usuários adscritos por serviço variam de 700 a 115.673 habitantes; 35% dos serviços possuem menos de 4.000 habitantes adscritos. A distribuição de médicos e enfermeiros variou de 0,14 a 5,71 por 4.000 habitantes. Serviços com elevada densidade populacional possuem modelo operacional tradicional e déficit de profissionais. As regiões das Ilhas e do Extremo Sul, locais com elevada mortalidade infantil, apresentam, em maior área territorial, número adequado de médicos e enfermeiros. Observou-se elevada heterogeneidade na distribuição da mortalidade infantil (zero a 52,63 por 1.000 nascidos vivos) em 2014. Conclusão: Um terço da população de Porto Alegre é assistida pela saúde da família. Locais com elevada mortalidade infantil apresentaram número de médicos e enfermeiros próximo ao preconizado. Esse estudo é gerador de hipótese para futuras investigações epidemiológicas na área de atenção primária.

Rozvoj moderních technologií ICT předpokládá mimo jiné efektivní, důkazně i bezpečnostně spolehlivý nástroj umožňující identifikaci či autentizaci uživatelů služeb informační společnosti. Tyto verifikační nástroje mají zpravidla podobu buď toho, co má osoba u sebe (např. USB token), nebo toho, co zná (typicky přihlašovací údaje), případně toho, čím daná osoba je (tj. biometrická charakteristika). Poslední z uvedených prostředků nabývá v moderních technologiích stále více na významu, a to zejména pro svou praktičnost (dostupnost a neměnitelnost). Zároveň však představuje zvláštní a privilegovanou kategorii osobních údajů, jejíž použití je silně limitováno předpisy veřejného práva. Existuje zde tak určitě konflikt mezi veřejným zájmem (či i zájmem jednotlivců) na práci s biometrickými údaji na straně jedné a řadou dalších práv, včetně práva na ochranu soukromého života, na straně druhé. Cílem tohoto článku je tak zmapovat současný český právní rámec regulující zpracovávání biometrických údajů pro různé účely; v souvislosti s tím se bude rovněž zabývat možným využitím biometrických prostředků, a to jak v oblasti práva veřejného, tak i soukromého. Příspěvek tak analyzuje jednotlivé právní režimy zpracování této privilegované kategorie dat, přičemž zároveň se snaží najít či blíže identifikovat existující právní mantinely a konflikty souvisejících režimů zpracování vyplývající z české i evropské právní úpravy.

Context.—

In Gleason score (GS) 7 prostate cancers, the quantity of Gleason pattern 4 (GP 4) is an important prognostic factor and influences treatment decisions. Magnetic resonance imaging (MRI)–targeted biopsy has been increasingly used in clinical practice.

Objective.—

To investigate whether MRI-targeted biopsy may detect GS 7 prostate cancer with greater GP 4 quantity, and whether it improves biopsy/radical prostatectomy GS concordance.

Design.—

A total of 243 patients with paired standard and MRI-targeted biopsies with cancer in either standard or targeted or both were studied, 65 of whom had subsequent radical prostatectomy. The biopsy findings, including GS and tumor volume, were correlated with the radical prostatectomy findings.

Results.—

More prostate cancers detected by MRI-targeted biopsy were GS 7 or higher. Mean GP 4 percentage in GS 7 cancers was 31.0% ± 29.3% by MRI-targeted biopsy versus 25.1% ± 29.5% by standard biopsy. A total of 122 of 218 (56.0%) and 96 of 217 (44.2%) prostate cancers diagnosed on targeted biopsy and standard biopsy, respectively, had a GP 4 of 10% or greater (P = .01). Gleason upgrading was seen in 12 of 59 cases (20.3%) from MRI-targeted biopsy and in 24 of 57 cases (42.1%) from standard biopsy (P = .01). Gleason upgrading correlated with the biopsy cancer volume inversely and GP 4 of 30% or less in standard biopsy. Such correlation was not found in MRI-targeted biopsy.

Conclusions.—

Magnetic resonance imaging–targeted biopsy may detect more aggressive prostate cancers and reduce the risk of Gleason upgrading in radical prostatectomy. This study supports a potential role for MRI-targeted biopsy in the workup of prostate cancer and inclusion of percentage of GP 4 in prostate biopsy reports.

Realizations of the Triple Point of Sulfur Hexafluoride in Transportable and Refillable Cells
Authors: Tew Weston L. , Quelhas Klaus N.
Published: July 2018

The Minamata Convention on Mercury has created a near-term need to develop alternative fixed points to replace the mercury triple point (Hg TP) for calibration of standard platinum resistance thermometers (SPRTs) on the International Temperature Scale of 1990 (ITS-90). The sulfur hexafluoride (SF6) TP is a good candidate to provide adequate “drop-in compatible” replacements for the lowest costs. We report our first results of SF6 TP realizations performed at the National Institute of Standards and Technology (NIST) using a new series of transportable and refillable triple-point cells. The melting curves are presented at various melted fractions F and compared to evaluate the reproducibility and overall uncertainty for the realizations. We obtained a TP temperature of 223.55587(33) K at F = 50 % and 223.55607(35) K at F = 100 % as a weighted average of realizations using two adiabatic-type cells and two immersion-type cells. (Unless otherwise stated, uncertainties are standard uncertainties corresponding to a 68 % confidence level.) Temperatures were derived using a combination of five different SPRTs as calibrated at NIST on the ITS-90. The data were evaluated over a region of the melting plateau for melted fraction F between 30 % ≤ F ≤ 80 % with a 0.2 mK wide melting range. The results from the immersion-type cells were used to derive an experimental value for the SF6 TP static head correction of −11.6(1.7) mK/m. This value implies an initial slope of the pressure-temperature (p-T) equilibrium melting line of 1.55 MPa/K, whichis in agreement with the value predicted via the Clapeyron equation. The uncertainties of these initial SF6 TP realizations are limitedby uncertainty in the realization of the ITS-90 (0.25 mK) and, to a lesser extent, static pressure head effects and chemical impurities.
Fábrica de Sueños, anhelos y necesidades. Las estrategias de la sociedad de consumo
Authors: Rodrigo Martín Luis
Published: July 2018

This article explores the main strategies that have come from the heart of consumer societies which, by means of commercial communication, marketing and publicity, have shaped a particular kind of citizen. Consumption shifted from satisfying people’s individual needs to a much more social and cultural level where imitation, status and new ways of integration in the social structure are closely related to consumer goods and services. Obsolescence, fashion, planned chaos and hedonism are some of the main strategies that are analyzed in this research.
