The physical mechanisms that quench star formation, turning blue star-forming galaxies into red quiescent galaxies, remain unclear. In this Letter, we investigate the role of gas supply in suppressing star formation by studying the molecular gas content of post-starburst galaxies. Leveraging the wide area of the Sloan Digital Sky Survey, we identify a sample of massive intermediate-redshift galaxies that have just ended their primary epoch of star formation. We present Atacama Large Millimeter/submillimeter Array CO(2-1) observations of two of these post-starburst galaxies at z ∼ 0.7 with

and

are an order of magnitude larger than comparable-mass galaxies in the local universe. Our observations suggest that quenching does not require the total removal or depletion of molecular gas, as many quenching models suggest. However, further observations are required both to determine if these apparently quiescent objects host highly obscured star formation and to investigate the intrinsic variation in the molecular gas properties of post-starburst galaxies.
Bayesian state-space models with multiple CPUE data: the case of a mullet fishery
Authors: Sant’Ana Rodrigo , Gerhard Kinas Paul , Villwock de Miranda Laura , Schwingel Paulo Ricardo , Castello Jorge Pablo , Paes Vieira João
Published: September 2017

We propose a novel Bayesian hierarchical structure of state-space surplus production models that accommodate multiple catch per unit effort (CPUE) data of various fisheries exploiting the same stock. The advantage of this approach in data-limited stock assessment is the possibility of borrowing strength among different data sources to estimate reference points useful for management decisions. The model is applied to thirteen years of data from seven fisheries of the lebranche mullet (Mugil liza) southern population, distributed along the southern and southeastern shelf regions of Brazil. The results indicate that this modelling strategy is useful and has room for extensions. There are reasons for concern about the sustainability of the mullet stock, although the wide posterior credibility intervals for key reference points preclude conclusive statistical evidence at this time
Anchovy (Engraulis encrasicolus) otoliths reveal growth differences between two areas of the Spanish Mediterranean Sea
Authors: Ventero Ana , Iglesias Magdalena , Villamor Begoña
Published: September 2017

Anchovy is a commercial species that supports large fisheries in the Mediterranean Sea. In addition, anchovy is an essential element of the pelagic food web, playing a considerable role in connecting the lower and upper trophic levels. Comparisons made regarding length frequency distribution, demographic structure, growth during the first year inferred from otoliths, and the condition factor of anchovy inhabiting the Spanish Mediterranean Sea (General Fisheries Commission for the Mediterranean management units, GSA06-Ebro Delta and 01-Alboran Sea), based on five-year data, clearly showed significant growth differences between areas and evidenced the existence of two independent anchovy stocks in the Spanish Mediterranean Sea. The anchovies inhabiting the Alboran Sea had higher growth than the anchovies inhabiting the Ebro Delta for the same age (one year old). The dramatic decline of the Alboran Sea anchovy could be related to the current management legislation in the Spanish Mediterranean Sea, based mainly on a common minimum catch size (9 cm), which should be revised given that sustainable anchovy exploitation is crucial for the pelagic food web equilibrium.
The SPOC manual Chapter 3 material balance
Authors: Laguitton D , Hodouin D
Published: September 2017

This chapter of the SPOC manual has been developed for the participants to a workshop on material balance computation. The various methods of material balance calculation are reviewed in order of increasing complexity. The two packages BILMAT and MATBAL are
largely documented in Chapters 3.1 and 3.2 to which the reader is referred. The justification of methods requiring computers is presented on the basis of a search for best estimators, i.e., estimators that take into consideration as much experimental information as possible in order to provide "well
informed" estimates. Each family of methods is illustrated by numerical exercises.

The STAMP progrann is a conversational package dedicated to experimental data analysis. STAMP features data entry and data file maintenance, various regression methods (including simple linear regression, multiple linear regression, stepwise linear regression,
polynomial regression) and three non-linear optimization algorithms (Powell, Simplex and Rosenbrock). Options selection is menu driven. This manual is a user's guide to the program and includes a detailed sample run. The version of the program described here (STAM P84) was written in FORTRAN for a
Cyber 730 computer. It easily runs in a 70 K octal memory (56 K decimal) but uses file structure and FORTRAN routines specific to Cyber. A version is also available for an IBM environment
Rockbursts in Ontario mines during 1984
Authors: Hedley D G F , Wetmiller R J
Published: September 2017

During 1984, more than 100 rockbursts occurred in seven mines in Ontario; a significant increase over previous years. An unusual feature was the multiple rockburst sequence that occurred in four mines over periods ranging from a few hours to months. These
rockbursts were recorded on the regional seismograph networks, and, in most cases, on the microseismic systems installed in the mines. It was possible to match magnitude values from the regional network to accurate source location from the mine networks, which greatly assisted in evaluating
mechanisms, causes, and spread of rockburst activity. Most rockburst activity occurred in pillars in thin tabular orebodies, either gently dipping as at Elliot Lake, or steeply dipping as at Red Lake and Kirkland Lake. Some rockbursts in the Sudbury mines have been attributed to a fault-slip
mechanism.

Published: September 2017

On emploie couramment dans les piliers sujets aux coups de toit, à l'intérieur des corps minéralisés minces et de fort pendage, des tirs de mine pour effectuer la relaxation des contraintes. Il s'agit de fracturer la roche et de réduire
les contraintes qui s'exercent sur le pilier concerné. Depuis 1982, on a effectué quatre tirs de relaxation dans des piliers de la mine de Campbell Red Lake, avec plus ou moins de succès. En général, on a employé, pour préparer les tirs de relaxation, un
procédé conforme au bon sens. On a divisé ce rapport en trois parties. Dans la première, on examine le principe de la mécanique des roches en rapport avec la relaxation des contraintes. On cherche à identifier les paramètres qui favorisent un tir de relaxation
réussi. La principale conclusion à laquelle on parvient est que la relaxation des contraintes sert principalement à réduire l'énergie potentielle de la masse rocheuse. Pour ce faire, on fracture le pilier et on laisse converger le toit et le mur de la galerie de mine. Dans
la seconde partie du rapport, on décrit les trois premiers tirs de relaxation effectués dans les piliers de couronne exploités par tranches montantes remblayées, et les piliers de base de chantier exploités par la méthode des chambresmagasins. On décrit dans cet
article les raisons pour lesquelles on procède à la relaxation des contraintes, ainsi que la conception et les instruments utilisés, et les observations faites après les tirs de relaxation.
Further study on source parameters at Quirke mine, Elliot Lake, Ontario
Authors: Chen S
Published: September 2017

A further analysis on source parameters for thirty-seven mining-induced seismic events at Quirke Mine, Elliot Lake, Ontario, has been carried out to study the self-similarity assumption in scaling law of seismic spectrum for mining-induced microearthquakes, and
to understand the focal mechanism in the mine. Evidence from high P-wave energy in a ratio Ep / Es of 5% to 30%, and about 80% of the events with Es /Ep <10% support the statement that most of the events for the data set in the mine are most likely to be candidates for
nondouble-couple focal mechanisms. They are also characterized by low stress release, especially low apparent stress under the limit of 0.2 Au, and a low total seismic energy. For the same seismic moment, the total energy values vary within a range of 10 KPa to 200 KPa of apparent stress, which
agrees with data from the Heinrich Robert Mine in Germany. Also it is found that the Gutenberg-Richter energy evaluation fits very well with the combined data set of magnitudes for Quirke Mine (0.7 to 2.3 Mn), and for Heinrich Robert Mine (1.2 to 2.3 ML) ' For the same total seismic energy, the
apparent stress is limited by 80 GN.m and 800 GN.m of seismic moment. The observed stress drop is dependent on the seismic moment, which implies a breakdown in scaling law for events induced by mining. An analysis of peak particle velocity and acceleration presents the evidence for seismic
attenuation over the fractured zone above the rockburst area in the mine.

Integral Formula for Spectral Flow for -Summable Operators
Authors: Georgescu Magdalena Cecilia
Published: September 2017

Fix a von Neumann algebra ${\mathcal{N}}$ equipped with a suitable trace $\unicode[STIX]{x1D70F}$. For a path of self-adjoint Breuer–Fredholm operators, the spectral flow measures the net amount of spectrum that moves from negative to non-negative. We consider specifically the case of paths of bounded perturbations of a fixed unbounded self-adjoint Breuer–Fredholm operator affiliated with ${\mathcal{N}}$. If the unbounded operator is $p$-summable (that is, its resolvents are contained in the ideal $L^{p}$), then it is possible to obtain an integral formula that calculates spectral flow. This integral formula was first proved by Carey and Phillips, building on earlier approaches of Phillips. Their proof was based on first obtaining a formula for the larger class of $\unicode[STIX]{x1D703}$-summable operators, and then using Laplace transforms to obtain a $p$-summable formula. In this paper, we present a direct proof of the $p$-summable formula that is both shorter and simpler than theirs.

Abstract. The present study offers the first chemical characterization of the submicron (PM1) fraction in western Africa at a high time resolution, thanks to collocated measurements of nonrefractory (NR) species with an Aerosol Chemical Speciation Monitor (ACSM), black carbon and iron concentrations derived from absorption coefficient measurements with a 7-wavelength Aethalometer, and total PM1 determined by a TEOM-FDMS (tapered element oscillating microbalance–filtered dynamic measurement system) for mass closure. The field campaign was carried out over 3 months (March to June 2015) as part of the SHADOW (SaHAran Dust Over West Africa) project at a coastal site located in the outskirts of the city of Mbour, Senegal. With an averaged mass concentration of 5.4 µg m−3, levels of NR PM1 in Mbour were 3 to 10 times lower than those generally measured in urban and suburban polluted environments. Nonetheless the first half of the observation period was marked by intense but short pollution events (NR PM1 concentrations higher than 15 µg m−3), sea breeze phenomena and Saharan desert dust outbreaks (PM10 up to 900 µg m−3). During the second half of the campaign, the sampling site was mainly under the influence of marine air masses. The air masses on days under continental and sea breeze influences were dominated by organics (36–40 %), whereas sulfate particles were predominant (40 %) for days under oceanic influence. Overall, measurements showed that about three-quarters of the total PM1 were explained by NR PM1, BC (black carbon) and Fe (a proxy for dust) concentrations, leaving approximately one-quarter for other refractory species. A mean value of 4.6 % for the Fe ∕ PM1 ratio was obtained. Source apportionment of the organic fraction, using positive matrix factorization (PMF), highlighted the impact of local combustion sources, such as traffic and residential activities, which contribute on average to 52 % of the total organic fraction. A new organic aerosol (OA) source, representing on average 3 % of the total OA fraction, showed similar variation to nonrefractory particulate chloride. Its rose plot and daily pattern pointed to local combustion processes, i.e., two open waste-burning areas located about 6 and 11 km away from the receptor site and to a lesser extent a traditional fish-smoking location. The remaining fraction was identified as oxygenated organic aerosols (OOA), a factor that prevailed regardless of the day type (45 %) and was representative of regional (approximately three-quarters) but also local (approximately one-quarter) sources due to enhanced photochemical processes.
Calibration and evaluation of CCD spectroradiometers for ground-based and airborne measurements of spectral actinic flux densities
Authors: Bohn Birger , Lohse Insa
Published: September 2017

Abstract. The properties and performance of charge-coupled device (CCD) array spectroradiometers for the measurement of atmospheric spectral actinic flux densities (280–650 nm) and photolysis frequencies were investigated. These instruments are widely used in atmospheric research and are suitable for aircraft applications because of high time resolutions and high sensitivities in the UV range. The laboratory characterization included instrument-specific properties like the wavelength accuracy, dark signal, dark noise and signal-to-noise ratio (SNR). Spectral sensitivities were derived from measurements with spectral irradiance standards. The calibration procedure is described in detail, and a straightforward method to minimize the influence of stray light on spectral sensitivities is introduced. From instrument dark noise, minimum detection limits  ≈  1  ×  1010 cm−2 s−1 nm−1 were derived for spectral actinic flux densities at wavelengths around 300 nm (1 s integration time). As a prerequisite for the determination of stray light under field conditions, atmospheric cutoff wavelengths were defined using radiative transfer calculations as a function of the solar zenith angle (SZA) and total ozone column (TOC). The recommended analysis of field data relies on these cutoff wavelengths and is also described in detail taking data from a research flight on HALO (High Altitude and Long Range Research Aircraft) as an example. An evaluation of field data was performed by ground-based comparisons with a double-monochromator-based, highly sensitive reference spectroradiometer. Spectral actinic flux densities were compared as well as photolysis frequencies j(NO2) and j(O1D), representing UV-A and UV-B ranges, respectively. The spectra expectedly revealed increased daytime levels of stray-light-induced signals and noise below atmospheric cutoff wavelengths. The influence of instrument noise and stray-light-induced noise was found to be insignificant for j(NO2) and rather limited for j(O1D), resulting in estimated detection limits of 5  ×  10−7 and 1  ×  10−7 s−1, respectively, derived from nighttime measurements on the ground (0.3 s integration time, 10 s averages). For j(O1D) the detection limit could be further reduced by setting spectral actinic flux densities to zero below atmospheric cutoff wavelengths. The accuracies of photolysis frequencies were determined from linear regressions with data from the double-monochromator reference instrument. The agreement was typically within ±5 %. Because optical-receiver aspects are not specific for the CCD spectroradiometers, they were widely excluded in this work and will be treated in a separate paper, in particular with regard to airborne applications.
Oceanic response to changes in the WAIS and astronomical forcing during the MIS31 superinterglacial
Authors: Justino Flavio , Lindemann Douglas , Kucharski Fred , Wilson Aaron , Bromwich David , Stordal Frode
Published: September 2017

Abstract. Marine Isotope Stage 31 (MIS31, between 1085 and 1055 ka) was characterized by higher extratropical air temperatures and a substantial recession of polar glaciers compared to today. Paleoreconstructions and model simulations have increased the understanding of the MIS31 interval, but questions remain regarding the role of the Atlantic and Pacific oceans in modifying the climate associated with the variations in Earth's orbital parameters. Multi-century coupled climate simulations, with the astronomical configuration of the MIS31 and modified West Antarctic Ice Sheet (WAIS) topography, show an increase in the thermohaline flux and northward oceanic heat transport (OHT) in the Pacific Ocean. These oceanic changes are driven by anomalous atmospheric circulation and increased surface salinity in concert with a stronger meridional overturning circulation (MOC). The intensified northward OHT is responsible for up to 85 % of the global OHT anomalies and contributes to the overall reduction in sea ice in the Northern Hemisphere (NH) due to Earth's astronomical configuration. The relative contributions of the Atlantic Ocean to global OHT and MOC anomalies are minor compared to those of the Pacific. However, sea ice changes are remarkable, highlighted by decreased (increased) cover in the Ross (Weddell) Sea but widespread reductions in sea ice across the NH.
UDASH – Unified Database for Arctic and Subarctic Hydrography

Published: September 2017

Abstract. UDASH is a unified and high-quality temperature and salinity data set for the Arctic Ocean and the subpolar seas north of 65° N for the period 1980–2015. The archive aims at including all publicly available data and so far consists of 288 532 oceanographic profiles measured mainly with conductivity/temperature/depth (CTD) probes, bottles, mechanical thermographs and expendable thermographs. The data were collected by ships, ice-tethered profilers, profiling floats and other platforms. To achieve a uniform quality level, suitable for a wide range of oceanographic analyses, approximately 74 million single measurements of temperature and salinity were thoroughly quality-checked. A large number of duplicate and erroneous profiles were detected and not included into the archive. Data outliers, suspicious gradients and other suspect data were flagged for quick identification. The final archive provides a unique and simple way of accessing most of the available temperature and salinity data for the Arctic Mediterranean Sea and can be downloaded from https://doi.org/10.1594/PANGAEA.872931.
Time-stamp correction of magnetic observatory data acquired during unavailability of time-synchronization services
Authors: Coïsson Pierdavide , Telali Kader , Heumez Benoit , Lesur Vincent , Lalanne Xavier , Xin Chang Jiang
Published: September 2017

Abstract. During magnetic observatory data acquisition, the data time stamp is kept synchronized with a precise source of time. This is usually done using a GPS-controlled pulse per second (PPS) signal. For some observatories located in remote areas or where internet restrictions are enforced, only the magnetometer data are transmitted, limiting the capabilities of monitoring the acquisition operations. The magnetic observatory in Lanzhou (LZH), China, experienced an unnoticed interruption of the GPS PPS starting 7 March 2013. The data logger clock drifted slowly in time: in 6 months a lag of 27 s was accumulated. After a reboot on 2 April 2014 the drift became faster, −2 s per day, before the GPS PPS could be restored on 8 July 2014. To estimate the time lags that LZH time series had accumulated, we compared it with data from other observatories located in East Asia. A synchronization algorithm was developed. Natural sources providing synchronous events could be used as markers to obtain the time lag between the observatories. The analysis of slices of 1 h of 1 s data at arbitrary UTC allowed estimating time lags with an uncertainty of ∼ 11 s, revealing the correct trends of LZH time drift. A precise estimation of the time lag was obtained by comparing data from co-located instruments controlled by an independent PPS. In this case, it was possible to take advantage of spikes and local noise that constituted precise time markers. It was therefore possible to determine a correction to apply to LZH time stamps to correct the data files and produce reliable 1 min averaged definitive magnetic data.
Multi-scale modeling of urban air pollution: development and application of a Street-in-Grid model by coupling MUNICH and Polair3D
Authors: Kim Youngseob , Wu You , Seigneur Christian , Roustan Yelva
Published: September 2017

Abstract. A new multi-scale model of urban air pollution is presented. This model combines a chemical-transport model (CTM) that includes a comprehensive treatment of atmospheric chemistry and transport at spatial scales down to 1 km and a street-network model that describes the atmospheric concentrations of pollutants in an urban street network. The streetnetwork model is the Model of Urban Network of Intersecting Canyons and Highways (MUNICH), which consists of two 5 main components: a street-canyon component and a street-intersection component. MUNICH is coupled to the Polair3D CTM of the Polyphemus air quality modeling platform to constitute a Street-in-Grid (SinG) model. MUNICH is used to simulate the concentrations of the chemical species in the urban canopy, which is located in the lowest layer of Polair3D, and the simulation of pollutant concentrations above roof-tops is performed by Polair3D. Interactions between MUNICH and Polair3D occur at roof level and depend on a vertical mass transfer coefficient that is a function of atmospheric turbulence. SinG is 10 used to simulate the concentrations of nitrogen oxides (NOx) and ozone (O3) in a Paris suburb. Simulated concentrations are compared to NOx concentrations measured at two monitoring stations within a street canyon. SinG shows better performance than MUNICH for nitrogen dioxide (NO2) concentrations. However, both SinG and MUNICH underestimate NOx. Model performance for NOx concentrations is not sensitive to using a complex chemistry model in MUNICH and the Leighton NO/NO2/O3 set of reactions is sufficient.
A Simple Temperature-Based Method to Estimate Heterogeneous
Frozen Ground within a Distributed Watershed Model
Authors: Follum Michael L. , Niemann Jeffrey D. , Parno Julie , Downer Charles W.
Published: September 2017

Abstract. Frozen ground can be important to flood production and is often heterogeneous within a watershed due to spatial variations in the available energy, insulation by snowpack and ground cover, and the thermal and moisture properties of the soil. The widely-used Continuous Frozen Ground Index (CFGI) model is a degree-day approach and identifies frozen ground using a simple frost index, which varies mainly with elevation through a temperature-elevation relationship. Similarly, snow depth and its insulating effect are also estimated based on elevation. The objective of this work is to more accurately represent the spatial heterogeneity of frozen ground in a distributed hydrologic model, Gridded Surface Subsurface Hydrologic Analysis (GSSHA), by modifying the CFGI method. Among the modifications, the snowpack and frost indices are simulated by replacing air temperature (a surrogate for the available energy) with a radiation-derived temperature that aims to better represent spatial variations in available energy. Ground cover is also included as an additional insulator of the soil. Furthermore, the modified Berggren Equation, which accounts for soil thermal conductivity and soil moisture, is used to convert the frost index into frost depth. The modified CFGI model is tested by application at six test sites within the Sleepers River Experimental Watershed in Vermont. Compared to the CFGI model, the modified CFGI model more accurately captures the variations in frozen ground between the sites, inter-annual variations in frozen ground depths at a given site, and the occurrence of frozen ground.
A dynamic thermal-mechanical model of the spindle-bearing system
Authors: Wang Haitong , Cai Yonglin , Wang Heng
Published: September 2017

Abstract. This paper presents a dynamic thermal-mechanical model to investigate the thermal characteristics in a spindle-bearing system. In this model, transient thermal analysis, static structure analysis and calculation of the boundary conditions are conducted as a solution loop. The transient boundary conditions, such as bearing stiffness, bearing heat generation and thermal contact conductance, are calculated with the appropriate formulas and solution methodology. The thermal feedbacks, which are seldom considered in the previous studies, are calculated in details. In order to validate the prediction accuracy, thermal equilibrium experiment is conducted on a test rig of spindle-bearing system. The predictions of the proposed model, such as bearing preload, temperature and thermal displacements, are in close agreement with the experiment results. The comparisons of the proposed model with two traditional simulations show that, the thermal feedbacks on the boundary conditions and thermal contact conductance are of great importance to the real-time estimation of the thermal characteristics. The proposed model provides a practical method to improve the prediction accuracy. It could also be generalized in other mechanical systems to investigate the dynamic thermal characteristics.

Published: September 2017

Background

Sedentariness, high inflammation status and malnutrition are highly prevalent in end-stage kidney disease patients on maintenance hemodialysis (MHD). This study investigated associations of weekly physical activity energy expenditure (PAEE) with clinical and anthropometric markers of nutrition and inflammation.

Methods

The analysis was performed using baseline cross-sectional data of 640 patients enrolled in the prospective cohort “The Prospective Study of the Prognosis of Patients Treated Chronically by Hemodialysis” (PROHEMO) developed in Salvador, BA, Brazil. The long version of the International Physical Activity Questionnaire was used to determine a summary measure of PAEE, the metabolic equivalent of task (MET), taking into account physical activities related to occupation, recreation, travel, sports, and housework. PAEE was the predictor variable. To assess associations of PAEE with outcomes, the sex-age-specific median MET was used. The malnutrition-inflammation score (MIS) with range of 0 to 30 (higher is worse), conicity index as indicator of abdominal adiposity and C-reactive protein (CRP) were the nutritional-inflammatory outcomes.

Results

The mean age of the patients was 48.9 ± 13.8 y, 60.3% were males, 16.7% diabetic, 88.1% nonwhite. In multivariable logistic regression models with adjustments for sociodemographic variables and comorbidities, PAEE ≤median was associated with MIS ≥6 (odds ratio [OR] = 1.57; 95% confidence interval [CI] = 1.08, 2.29), conicity index ≥1.3 (OR = 1.52, 95% CI = 1.03, 2.23) and CRP >1.30 mg/dL (OR = 1.69, 95% CI = 1.08, 2.84).

Conclusions

Greater physical activity assessed by PAEE was associated with indicators of better nutritional and inflammation status. These results indicate opportunities for improving outcomes in MHD patients by counseling and treatment intervention.
Effect of the Different Implant Protocols on Peri-Implant Bone: A 6-Month Prospective Study in Beagle Dogs
Authors: Song Dandan , Zheng Hui , Huang Yan , Ma Xucheng , Ma Guowu , Liang Xin
Published: September 2017

Objective

To compare the effects of different implant placement and loading protocols on the marginal bone loss (MBL) in beagles by intraoral radiography.

Methods and materials

61 dental implants were inserted on 9 beagle dogs at bilateral lower posteriors according to 8 different protocols: immediate implant placement and immediate loading for 3 months (IIP + IL3) or 6 months (IIP + IL6) and unloading (IIP + UL), immediate implant placement and delayed loading for 3 months (IIP + DL3) or 6 months (IIP + DL6), delayed implant placement and immediate loading for 3 months (DIP + IL3) or delayed loading for 3 months (DIP + DL3) and unloading (DIP + UL). Intraoral radiography was performed to analyze the MBL during each surgery, before and after the implant placement and at 3-month intervals after the procedure.

Results

In total, 57 samples were included. There was less MBL (p<0.05) in the IIP + IL3 group (1.22 ± 0.63 mm) compared to the DIP + IL3 group (1.89 ± 0.9 mm). The longer the loading time, the more bone loss appeared in the IIP + IL group; however, the results were reversed in the IIP + DL group. The MBL during the latter 3-month period was dramatically decreased compared to the former 3-month period in the IIP + DL3 group (p<0.05).

Conclusions

The IIP + IL group seems superior to the DL protocol and the MBL changed significantly during the first three months and thereafter became stable.
Serum Albumin Levels in Relation to Tumor Parameters in Hepatocellular Carcinoma Patients
Authors: Carr Brian I. , Guerra Vito
Published: September 2017

Background

Serum albumin levels have been shown to have prognostic significance in hepatocellular carcinoma (HCC), as part of an inflammatory index. The aim of this study was to examine the possible relationship of serum albumin levels to parameters of HCC aggressiveness.

Methods

A large HCC patient cohort was retrospectively examined, and the possible relationships of albumin levels to tumor diameter, multifocality, portal vein thrombosis (PVT) and α-fetoprotein levels were examined.

Results

HCC patients with lower serum albumin levels had significantly larger maximum tumor diameters, greater prevalence of PVT, increased tumor multifocality and higher α-fetoprotein levels, than HCC patients with higher albumin levels. A correlation was found between levels of these tumor parameters and serum albumin levels.

Conclusions

These results indicate that low serum albumin levels correlate with increased parameter measures of HCC aggressiveness, in addition to their role as a monitor of systemic inflammation. Decreased serum albumin might have a role in HCC aggressiveness.
Use of intravenous epoprostenol as a treatment for the digital vasculopathy associated with the scleroderma spectrum of diseases
Authors: Law Shing T. , Farber Harrison W. , Simms Robert W.
Published: September 2017

Introduction

Intravenous prostanoid therapy is recommended for severe systemic sclerosis-related digital vasculopathy. The evidence supporting this recommendation is limited. The aim of this study was to evaluate the safety and efficacy of treating scleroderma spectrum digital vasculopathy with intravenous epoprostenol.

Methods

Patients with a diagnosis of systemic sclerosis who had received intravenous epoprostenol for scleroderma spectrum digital vasculopathy between 1st October 2003 and 1st September 2015 at Boston University Medical Center were identified using ICD-9 code search, and their charts were reviewed in this retrospective case series.

Results

Of 47 encounters for intravenous epoprostenol infusion for scleroderma spectrum digital vasculopathy, 29 had documentation of improvement as indicated by any of the following: pain relief, increased perfusion of digits as assessed by warmth or color, reduced digital ulcer number or size. In 16 encounters, there was no documentation on whether the indicative condition had improved. No deterioration of the indicative condition was documented in any encounters. Intravenous epoprostenol infusion was well tolerated with few significant adverse effects.

Conclusions

Intravenous epoprostenol infusion in the treatment of scleroderma spectrum digital vasculopathy is safe. The condition improved with intravenous epoprostenol infusion, although there were study design constraints. We describe our protocol for administering intravenous epoprostenol infusion for scleroderma spectrum digital vasculopathy to improve consistency of patient care.

Purpose

Diagnostic challenges are common in clinical practice and diagnostic or classification criteria for musculoskeletal conditions cannot overshadow clinical skills.

Methods

We present the case of a young man who complained of prolonged articular pain and mild swelling of the right ankle in the absence of other remarkable data. Apparently fulfilling the Budapest diagnostic criteria for complex regional pain syndrome, the patient was treated accordingly, but the pain increased over time. Then the patient underwent an additional diagnostic workup including synovial and bone biopsies in 2 separate occasions with the second one demonstrating diffuse lymphoid infiltrate compatible with lymphoma.

Results

The conclusive diagnosis of primary diffuse large B-cell lymphoma of the talus was made and adequate treatment initiated.

Conclusions

Introduction

Although differentiation between benign and malignant small renal tumors (≤4 cm) is still difficult, it is a demand for decision making and determining the treatment strategy. Our aim is to evaluate the role of multidetector row computed tomography (MDCT) in the differentiation of small renal clear cell carcinoma (RCC) and renal oncocytoma (RO).

Methods

We reviewed triphasic computed tomographic (CT) scans performed in 43 patients diagnosed with RCC (n = 23) and RO (n = 21). After an unenhanced CT phase of the upper abdomen, triple-phase acquisition included a cortico-medullary phase (CMP), a nephrographic phase (NP), and a pyelographic phase (PP), and lesions were evaluated both qualitatively and quantitatively.

Results

RCCs were hypervascular in 13 cases and hypovascular in 10 cases, while ROs were hypervascular in nine cases and hypovascular in 12 cases. Mean attenuation values (MAVs) for hypervascular RCCs and hypervascular ROs on unenhanced examination were 34.0 ± 7.1 and 31.3 ± 8.1 HU, respectively. Enhancement in CMP was 173.1 ± 45.2 HU for RCCs and 151.1 ± 36.0 HU for ROs and a gradual wash-out in NP (148.8 ± 34.3 and 137.1 ± 33.9 HU for RCCs and ROs, respectively) and in PP (98.2 ± 36.0 HU for RCCs and 79.4 ± 21.5 HU for ROs) was observed. MAV for hypovascular RCCs and hypovascular ROs on unenhanced examination were 32.4 ± 12.0 and 28.9 ± 8.0 HU, respectively. Both hypovascular RCCs and ROs showed a statistically significant difference in each post contrastographic phase.

Conclusions

Absolute attenuation and the quantitative amount of the enhancement were not strong predictors for RO and RCC differentiation.

Authors: Itagiba-Fonseca Maria Cristina , Barroso Sabrina Martins
Published: September 2017

A Esclerose Múltipla (EM) é uma doença crônica e progressiva, que causa perdas motoras sensoriais e psicológicas. Objetivo: Compreender o processo de luto e enfrentamento de pessoas com esclerose múltipla, em diferentes períodos do diagnóstico, sob enfoque das proposições teóricas de Kübler-Ross sobre o processo de luto. Método: Foram realizadas entrevistas semiestruturadas e foi feita a aplicação das pranchas um e 11 do Teste de Apercepção Temática a três mulheres, uma delas estava em investigação diagnóstica para EM, uma tinha diagnóstico de EM há um ano e a terceira havia sido diagnosticada com EM há cinco anos. Utilizou-se análise de conteúdo temática para organização dos dados e a teoria do luto de Kübler-Ross para analisá-los. Resultados: Diferenças na forma como cada participante lidava com a EM puderam ser observadas. As participantes com diferentes períodos de diagnóstico/investigação vivenciavam fases distintas do processo de luto e utilizavam diferentes tipos de estratégias de enfrentamento. Conclusões: O adoecimento conduz ao luto, que pode ser uma forma para realizar o enfrentamento e ressignificar a vida na nova condição.
Do que o bebê precisa? A função de cuidar na perspectiva das educadoras de bercário
Authors: Polli Rodrigo Gabbi , Lopes Rita De Cassia Sobreira
Published: September 2017

O presente estudo teve por objetivo investigar a função de cuidar na perspectiva das educadoras de berçário. Participaram desse estudo quinze educadoras de berçário de duas creches públicas federais de Porto Alegre/RS. As educadoras responderam a entrevistas e as suas respostas foram examinadas através de análise de conteúdo qualitativa. Os resultados evidenciaram que as educadoras consideram o bebê como foco do seu trabalho, estando o serviço da creche voltado para o atendimento das suas necessidades. Contudo, cuidar de bebês é uma tarefa emocionalmente exigente. Frente a isso, destaca-se a importância de se oferecer condições adequadas de trabalho para as educadoras e espaços de escuta para que elas possam realizar as suas funções.
A percepção do corpo em pacientes bariátricos e a experiência do medo do reganho do peso
Authors: Marchesini Simone Dallegrave , Antunes Maria Cristina
Published: September 2017

O presente artigo analisou alterações na percepção corporal e medo do reganho de peso em 10 pacientes submetidos à cirurgia bariátrica de Fobi-Capella (Bypass Gástrico em Y de Roux) há no mínimo quatro anos, que tiveram reganho de pelo menos 20% do peso perdido. Foi utilizado um roteiro de entrevista semiestruturada sobre: dados demográficos, hábitos alimentares, mudanças no estilo de vida e comportamentais, imagem corporal, preconceitos vivenciados e reaquisição de peso. As entrevistas foram gravadas, transcritas e submetidas à análise de conteúdo. Observou-se que o reganho de peso ocorreu de modo desapercebido pelo paciente, até que tenha sido sinalizado socialmente; o emagrecimento excessivo foi mal avaliado pelos pares; observou-se medo acentuado, por parte dos operados bariátricos, de voltar à obesidade mórbida; os participantes relataram alterações nas relações afetivas; a percepção da imagem corporal oscilou e era infiel à aparência externa.
Habilidades sociais e competência social: Analisando conceitos ao longo das obras de Del Prette e Del Prette
Authors: Comodo Camila Negreiros , Dias Talita Pereira
Published: September 2017

Considerando a diversidade conceitual do campo das Habilidades Sociais, tanto entre diferentes autores, como para um mesmo autor ao longo de suas obras, este estudo objetivou analisar as definições de habilidades sociais e competência social, a partir das obras de Del Prette e Del Prette. As definições dos conceitos foram selecionadas de livros e artigos teóricos desses autores, desde 1996 até 2012, e comparadas, em ordem cronológica. Com base nessas análises, observaram-se diferenças importantes em ambos os conceitos, ao longo das obras dos autores, produto de revisões, complementações e aprimoramentos de conhecimentos conceituais, empíricos e metodológicos que ocorreram ao longo do tempo.
A revisão criminal como instrumento de execução das sentenças dos tribunais internacionais de direitos humanos: o cenário brasileiro em comparação com a discussão italiana no caso Drassich
Authors: Vasconcellos Vinicius Gomes de , Capparelli Bruna
Published: September 2017

A partir de revisão bibliográfica e estudo comparado de caso italiano, este artigo pretende analisar a efetividade das decisões de tribunais internacionais de direitos humanos no âmbito interno do Estado-parte condenado por violação à norma convencional relacionada ao devido processo penal. Contudo, em razão da inexistência de força coercitiva das decisões internacionais em relação aos ordenamentos dos Estados-parte, o cumprimento e o respeito às normas convencionais e à jurisprudência das cortes internacionais dependem fundamentalmente da ação dos próprios Estados, internalizando tais ditames a partir dos seus respectivos regramentos normativos. Diante disso, há que se questionar a existência e a necessidade de mecanismos jurídicos que possibilitem a efetividade dos julgados dos tribunais internacionais. Trata-se de tema pouco explorado na doutrina pátria, além de não expressamente regulado pela legislação nacional. Assim, a partir do estudo exemplificativo de um caso italiano emblemático, propor-se-á a interpretação extensiva das hipóteses de revisão criminal do Código de Processo Penal brasileiro, para autorizar a reabertura do processo penal e a relativização da coisa julgada condenatória interna em razão da violação de direitos do acusado reconhecidos convencionalmente. Por fim, será apresentada proposta de reforma legislativa, para introduzir previsão expressa da “revisão criminal convencional”.
A terceirização debatida no parlamento brasileiro ante a experiência jurídica nacional e estrangeira: o Estado e a tutela do trabalho durante crises econômicas
Authors: Muçouçah Renato De Almeida Oliveira
Published: September 2017

Este estudo tem como objetivo analisar as discussões existentes no parlamento brasileiro acerca da regulamentação legal do fenômeno da terceirização. Há breve análise acerca do contexto em que se insere a terceirização no Brasil, economia capitalista de alta competitividade, que enfrenta crises financeiras e altos índices de desemprego. Com o auxílio da experiência jurídica estrangeira (notadamente europeia), busca-se verificar as respostas obtidas pelos países com as legislações adotadas: em muitos casos, constata-se que houve afronta a postulados básicos da dogmática jurídica trabalhista e o Estado de bem-estar social restou enfraquecido. Questiona-se, ademais, a produção e interpretação de normas jurídicas em tempos de crise, bem como o impacto de tais preceitos quanto a postulados constitucionais e trabalhistas. Para tanto, buscou-se o estudo hipotético-dedutivo das questões existentes nas lacunas do direito brasileiro, via análise dedutiva de bibliografia nacional e estrangeira especializadas na temática, e as hipóteses de resposta por elas apresentadas. O enfrentamento de crises econômicas, com o aval do Poder Judiciário, por meio de legislação criada para amenizá-las, avilta direitos fundamentais de natureza social, incluindo direitos individuais do trabalhador. E, ao contrário das crises, tais alterações são perenes e enfraquecem o Estado de bem-estar social, gerando retrocesso social, como observado em todas as experiências jurídicas estrangeiras já analisadas. Embora haja tentativas de retorno a um novo conceito de liberalismo econômico, a defesa constitucional não permite a reversão de conquistas já alcançadas, não permitindo assim que se legisle, em momentos de crise econômica ou desemprego, sobre retirada de direitos fundamentais do trabalhador.
Balancing Offshoring and Agility in the Apparel Industry: Lessons From Benetton and Inditex
Authors: Sartal Antonio , Martínez-Senra Ana , García José
Published: September 2017

Based on a case study from the apparel industry, the paper addresses how the organizational innovations adopted by Benetton and Inditex allowed them to balance lower production costs in developing countries with an adequate response time to frequent preference changes and increasing demands for customisation. Findings confirm the fragility of multinationals whose offshoring strategy has not considered the costs of coordinating suppliers in far-off locations and suggest organisational improvements that make production costs, variety and time to market goals compatible. Our research thus provides a view of the conditions and processes that can overcome in increasingly volatile environments the misalignment between demand changes and the limited reactivity of industrial infrastructures. Furthermore the innovation strategy of textile companies has created generalizable lessons for other sectors in which demand uncertainty is high, life cycles short, and customers are, to some extent, prepared to pay for “speed to market”.
Predicting Specific Stress of Cotton Staple Ring Spun Yarns: Experimental and Theoretical Results
Authors: Zubair Muhammad , Neckář Bohuslav , Malik Zilfiqar
Published: September 2017

The aim of this research is to predict the yarn specific stress from fiber specific stress and fiber stress utilisation. In this paper a new approach is introduced to predict the specific stress-strain curves of cotton carded and combed yarns. The force on single fiberis worked out and these fiber forces are combined together to obtain forces acting on yarn. The theoretical model introduces the utilisation of fiber stress on the basis of the fiber specific stress-strain curve, twist angle, fiber directional distribution parameter C and contraction ratio. A comparison of experimental results suggests that the specific stress-strain curves predicted have reasonable agreement with the experimental yarn specific stress-strain curves for all types of yarns. Thus this model is valid to predict the specific stress-strain curves for carded and combed cotton ring spun yarns.
