Synthesis of Nanoporous Carbon for Fast Uptake of Cr(VI) and Ni(II) from Aqueous Solution
Authors: Ghiloufi Imed 
Published: January 2017

ABSTRACT: Nanoporous carbon (NPC), based on organic xerogel compounds, was prepared at 650 °C pyrolysis temperature by sol–gel method from pyrogallol and formaldehyde (PF‐650) mixtures in water using picric acid as a catalyst. The performance of NPC was characterized by scanning electron microscopy, transmission electron microscopy, X‐ray diffraction and nitrogen porosimetry. The metal uptake characteristics were explored using effective parameters including pH, contact time, initial metal ion concentration, and temperature. Better adsorption of Cr(VI) and Ni(II) was observed at pH 2 and 4, respectively. The Langmuir model gave the better fit for Cr(VI), whereas for Ni(II), the Freundlich model is better than the other models. The kinetic studies revealed that the adsorption is fast and its data are well fitted by the pseudo‐second‐order kinetic model. The thermodynamic properties, i.e., ΔG°, and ΔS°, showed that adsorption of Cr(VI) and Ni(II) onto NPC was endothermic, spontaneous and feasible in the temperature range of 300 to 328 K.

Authors: Li Zhongtian , Stenstrom Michael K. , Li Xu 
Published: January 2017

ABSTRACT: The objective of this study is to characterize the removal of 17β‐estradiol (E2) and the microbial community of a biologically active carbon (BAC) reactor under acetic acid or humic acid as the primary carbon source. Influent E2 concentration was maintained at 20 μg/L. Higher than 99% removal of E2 was achieved by the BAC reactor. The concentration of E2 increased from below detection limit (<5.8 ng/L) to 48 ± 8 ng/L after switching the primary carbon source from acetic acid to humic acid in the reactor influent. Meanwhile, effluent estrone concentration increased from 50 ± 15 to 55 ± 15 ng/L after the switch of primary carbon source in the reactor influent. 17β‐estradiol degrading bacteria were isolated. Microbial community structures under different nutrient conditions were revealed by high throughput sequencing. The presence of readily biodegradable carbon source such as acetic acid benefited E2 removal in the BAC reactor.

Authors: Portilho Raphaela Magnino Rosa , De Sousa Ricardo José Leite 
Published: January 2017

O presente artigo busca analisar a celebração do pacto de não concorrência após o término da relação de emprego no âmbito do ordenamento jurídico brasileiro. O estudo implica a necessidade de verificação dos limites que podem ser impostos ao direito de liberdade de trabalho, que é garantido no art. 5º, inciso XIII, da Constituição de 1988, objetivando demonstrar que a pactuação da não concorrência não atenta contra essa garantia constitucional. Para tanto, a investigação também abarcará o conflito entre a liberdade de trabalho e a livre iniciativa e concorrência, todos direitos constitucionalmente garantidos, analisando a possibilidade de estabelecer-se uma composição que observe a proporcionalidade dos direitos cuja proteção é almejada.

<div>Modernisasi melalui peningkatan dan penggunaan teknologi alat tangkap serta bantuan permodalan berimplikasi pada kegiatan serta organisasi penangkapan ikan dan pada akhirnya terjadi perubahan dalam suatu komunitas. Tidak semua lapisan nelayan dapat memanfaatkan peluang modernisasi. Sebelum program modernisasi perikanan, struktur komunitas nelayan Suku Bajo masih didominasi oleh sistem perikanan tradisional, kegiatan dicirikan struktur komunitas homogen dan tingkat diferensiasi sosial yang masih rendah. Berbagai ukuran yang dapat dilihat menunjukan bahwa nelayan tergolong tidak sejahtera. Pemerintah memandang perlu untuk memperbaiki taraf hidup nelayan. Realisasinya dilakukan antara lain dalam bentuk modernisasi perikanan (Revolusi Biru). Penerimaan maupun penolakan suatu hal baru berkaitan dengan proses mental sejak seseorang mengetahui adanya inovasi. Proses tersebut bagi nelayan tidak terlepas dari pengaruh pemaknaan terhadap laut serta pekerjan nelayan bagi nelayan itu sendiri.</div><div> </div>Hasil penelitian menunjukan kecenderungan terjadi bahwa Pengadopsi Cepat (PC) memiliki karakteristik yang lebih baik dibandingkan adopter yang lebih lambat. Pada pemaknaan laut, kebanyakan responden memberi makna ekonomi, psikologi dan budaya yang positif. Sedangkan pada makna pekerjaan nelayan kebanyakan responden memberi makna ekonomi, sosiologis, teologis, dan budaya yang cenderung positif. Selain itu nampaknya terdapat hubungan antara pemaknaan dengan kecepatan adopsi. Hubungan tersebut adalah semakin positif makna ekonomis maka adopsi inovasi semakin cepat. Sebaliknya semakin positif makna budaya kecenderungan adopsi cenderung semakin lambat. Modernisasi perikanan berdampak pada perubahan pola kerja yakni daya jelajah lebih jauh, jumlah pekerja (sawi) lebih banyak dengan sifat semi bebas dan perekrutan lebih selektif. Pembagian kerja lebih jelas dan berjenjang serta hierarkis. Terjadi pula dampak perubahan struktur sosial dengan sistem bagi hasil yang menjadi pranata nelayan, stratifikasi yang kompleks, diferensiasi beragam, dan pola hubungan non eksploitatif. Dampak teknologi gae juga menghasilkan peningkatan pemenuhan kebutuhan dasar serta gizi anggota keluarga nelayan serta kesadaran pentingnya pendidikan bagi anggota keluarga
Low-temperature transformation to bainite in a medium-carbon steel

Published: January 2017

Abstract
The consequences of reducing the carbon concentration from 0.8 to 0.6 wt.% in a bulk nanostructured bainitic-steel have been investigated with the aim of enabling processing. We observed that the average thickness of the product phase plates increased from below 20–40 nm to about 100 nm after isothermal transformation at the same temperature. The increase in plate size led to decrease in hardness as expected. However the hardness reduction was not as large as might be expected, a transition to lower bainite at temperatures below 250°C may have provided additional strengthening. Transformation just below the martensite start temperature resulted in a mixture of martensite and bainite, with no observed increase in the rate of bainite transformation.

BackgroundArteriosclerotic disorders increase the risk of dementia. As they have common causes and risk factors, coronary heart disease (CHD) could influence the course of dementia.AimTo determine whether CHD increases the speed of cognitive decline in Alzheimer’s disease, and to discuss the potential for secondary cardiovascular prevention to modify this decline.Design and settingProspective multicentre cohort study in general practices in six cities in Germany.MethodParticipants were patients with probable mild-to-moderate Alzheimer’s dementia or mixed dementia (n = 118; mean age 85.6 [±3.4] years, range 80–96 years). The authors assessed the presence of CHD according to the family physicians’ diagnosis. Cognitive performance was measured during home visits for up to 3 years in intervals of 6 months, using Mini Mental State Examination (MMSE) and Clinical Dementia Rating Sum of Boxes (CDR-SoB). The authors also recorded whether patients died in the observation period.ResultsAt baseline, 65 patients (55%) had CHD and/or a heart condition following a myocardial infarction. The presence of CHD accelerated cognitive decline (MMSE, P<0.05) by about 66%, and reduced cognitive-functional ability (CDR-SoB, P<0.05) by about 83%, but had no impact on survival.ConclusionThe study shows that CHD has a significant influence on cognitive decline in older patients with late-onset dementia. The dementia process might therefore be positively influenced by cardiovascular prevention, and this possible effect should be further investigated.

Published: January 2017

SummaryPurpose: Medical imaging plays an important role in selecting patients with metastatic castration-resistant prostate cancer for 223Ra- dichloride therapy of bone metastases. The purpose of this study was to investigate whether 68Ga-PSMA-PET has incremental value over conventional imaging for selecting patients suitable for 223Ra-dichloride therapy. Methods: In 27 consecutive patients referred for 223Ra-dichloride therapy additional 68Ga-PSMA-PET/CT was performed and tracer distribution was evaluated systematically with respect to the detection of visceral metastases and bone metastases with inadequate uptake on bone scintigraphy. Results: In 4 patients (15 %) 68Ga- PSMA-PET revealed previously unknown visceral metastases (3 liver, 1 adrenal gland), which changed the therapeutic decision in 2 cases. PET revealed more extended tumour involvement in the bone compared to bone scintigraphy in 9 patients (33 %). In 3 of these, the mismatch was extensive enough to question suitability for 223Ra-dichloride therapy. Conclusions: Additional 68Ga-PSMA-PET as a gatekeeper between conventional staging and 223Ra-dichloride therapy can provide valuable additional information with regard to visceral metastases and tumour manifestations without adequate bone mineral turnover. It may lead to a change in therapeutic management in a significant number of patients and should therefore be considered in future clinical trials.
THE UNUSUALLY HIGH HALO CONCENTRATION OF THE FOSSIL GROUP NGC 6482: EVIDENCE FOR WEAK ADIABATIC CONTRACTION
Authors: Buote David A. 
Published: January 2017

ABSTRACT
Although fossil galaxy systems are thought to be very old, and thus should possess above-average halo concentrations, typically fossils have unexceptional concentrations of their masses. We revisit the massive isolated elliptical galaxy/fossil group NGC 6482 for which previous X-ray studies of a modest Chandra observation obtained a very uncertain, but also possibly very high, halo concentration. We present new measurements of the hot gas surface brightness, temperature, and iron abundance using the modest Chandra observation and a previously unpublished Suzaku observation, the latter of which allows the measurements of the gas properties to be extended out to

. By constructing hydrostatic equilibrium models of the gas with separate components for the gas, the stellar mass of the large central galaxy (BCG), and the dark matter (DM), we measure

and

using a Navarro-Frenk-White (NFW) DM profile. For a halo of this mass, the measured concentration c
200 exceeds the mean value (7.1) expected for relaxed ΛCDM halos by

in terms of the observational error, and by

considering the intrinsic scatter in the ΛCDM c–M relation, which situates NGC 6482 as the most extreme outlier known for a fossil system. We explored several variants of adiabatic contraction (AC) models and, while the AC models provide fits of the same quality as the uncontracted models, they do have the following advantages: (1) lower c
200 that is less of an outlier in the ΛCDM c–M relation, and (2) baryon fractions

that agree better with the mean cosmic value. While the standard AC prescriptions yield a BCG stellar mass that is uncomfortably low compared to results from stellar population synthesis (SPS) models, a weaker AC variant that artificially shuts off cooling and star formation at z = 2 yields the same stellar mass as the uncontracted models. These are probably the reasons why our X-ray analysis prefers this weaker AC variant applied to either an NFW or Einasto DM halo. Finally, the stellar mass we measure for the BCG from the hydrostatic analysis strongly favors results from SPS models with a Chabrier or Kroupa initial mass function (IMF) over a Salpeter IMF.
SOLAR ENERGETIC PARTICLE DRIFTS AND THE ENERGY DEPENDENCE OF 1 au CHARGE STATES
Authors: Dalla S. , Marsh M. S. , Battarbee M. 
Published: January 2017

ABSTRACT
The event-averaged charge state of heavy ion solar energetic particles (SEPs), measured at 1 au from the Sun, typically increases with the ions’ kinetic energy. The origin of this behavior has been ascribed to processes taking place within the acceleration region. In this paper we study the propagation through interplanetary space of SEP Fe ions, injected near the Sun with a variety of charge states that are uniformly distributed in energy, by means of a 3D test particle model. In our simulations, due to gradient and curvature drifts associated with the Parker spiral magnetic field, ions of different charge propagate with very different efficiencies to an observer that is not magnetically well connected to the source region. As a result we find that, for many observer locations, the 1 au event-averaged charge state

, as obtained from our model, displays an increase with particle energy E, in qualitative agreement with spacecraft observations. We conclude that drift-associated propagation is a possible explanation for the observed distribution of

versus E in SEP events, and that the distribution measured in interplanetary space cannot be taken to represent that at injection.
IMPACT OF BARYONIC PHYSICS ON INTRINSIC ALIGNMENTS
Authors: Tenneti Ananth , Gnedin Nickolay Y. , Feng Yu 
Published: January 2017

ABSTRACT
We explore the effects of specific assumptions in the subgrid models of star formation and stellar and active galactic nucleus feedback on intrinsic alignments of galaxies in cosmological simulations of the “MassiveBlack-II” family. Using smaller-volume simulations, we explore the parameter space of the subgrid star formation and feedback model and find remarkable robustness of the observable statistical measures to the details of subgrid physics. The one observational probe most sensitive to modeling details is the distribution of misalignment angles. We hypothesize that the amount of angular momentum carried away by the galactic wind is the primary physical quantity that controls the orientation of the stellar distribution. Our results are also consistent with a similar study by the EAGLE simulation team.
Définitions ostensives co-construites. Le cas de la visite guidée
Authors: Traverso Véronique , Ravazzolo Elisa 
Published: January 2017

Dans cette contribution, nous abordons l’activité interactionnelle de définition en nous focalisant sur l’imbrication des ressources de différentes natures – linguistiques, prosodiques, gestuelles et spatiales – que les participants mettent en jeu dans sa réalisation. Nous étudions la définition dans la visite guidée de deux jardins (un jardin ethnobotanique et un jardin « en mouvement »). Sur la base d’un fonctionnement récurrent observé, fondé sur les étapes successives de « mise en visibilité » d’un référent, « dénomination » et « définition », nous examinons les formats utilisés par les participants, en relation avec la temporalité de l’interaction et la nature du jardin. L’étude met en évidence comment les activités de définition transmettent la philosophie différente des deux jardins et offrent une appréhension bien différente du monde végétal.
La définition comme action multimodale pour des enjeux pratiques : définir pour instruire à l’auto-école
Authors: Deppermann Arnulf 
Published: January 2017

Cet article étudie les définitions en contexte d’instructions dans les leçons d’auto-école. Les observations s’appuient sur un corpus de 70 heures de leçons enregistrées par vidéo en Allemagne. Le moniteur utilise des définitions pour introduire des nouvelles expressions techniques qui sont étroitement liées aux buts de l’apprentissage de conduite. Pour leur production, l’emploi des ressources multimodales est fondamental. La définition ostensive par pointage et une assertion existentielle (ça/ici c’est X) est complétée par des définitions descriptives et des démonstrations gestuelles du maniement des objets. L’objectif des actes de définition ici n’est pas de délivrer une définition de l’expression en soi, qui soit valable pour tous les contextes possibles, mais de produire une définition qui soit efficace dans le contexte pratique concerné. Les définitions donc sont plutôt fragmentées, indexicales et situées, et elles sont adaptées aux pré-connaissances de l’interlocuteur.
Enjeux argumentatifs de la définition : l’exemple des débats sur l’ouverture du mariage aux couples de même sexe
Authors: Doury Marianne , Micheli Raphaël 
Published: January 2017

L’article explore les enjeux argumentatifs attachés à l’activité de définition du mot « mariage » menée dans le cadre de la discussion du projet de loi sur l’ouverture du mariage aux couples de même sexe à l’Assemblée nationale en 2013. On examine d’abord les conditions d’émergence de l’activité définitoire dans le cadre du Parlement ; on met en évidence une forte tension entre la dimension stipulatoire de la définition et sa dimension descriptive. On analyse ensuite les modalités selon lesquelles s’exprime le conflit de définitions. Enfin, on se penche sur les moments du débat où les députés adoptent une posture réflexive pour s’interroger sur les rapports qui unissent le langage et la réalité : le désaccord tient-il à une « simple » querelle de mots, facilement réglable, ou existe-t-il un lien intime, indissoluble, entre la définition que l’on octroie aux mots et la manière dont on perçoit le monde et dont on agit sur lui ?
