Toxicity of Plant Secondary Metabolites Modulating Detoxification Genes Expression for Natural Red Palm Weevil Pesticide Development
Authors: AlJabr Ahmed , Hussain Abid , Rizwan-ul-Haq Muhammad , Al-Ayedh Hassan
Published: January 2017

This study aimed to explore the larvicidal and growth-inhibiting activities, and underlying detoxification mechanism of red palm weevil against phenylpropanoids, an important class of plant secondary metabolites. Toxicity of α-asarone, eugenol, isoeugenol, methyl eugenol, methyl isoeugenol, coumarin, coumarin 6, coniferyl aldehyde, diniconazole, ethyl cinnamate, and rosmarinic acid was evaluated by incorporation into the artificial diet. All of the phenylpropanoids exhibited dose- and time-dependent insecticidal activity. Among all the tested phenylpropanoids, coumarin exhibited the highest toxicity by revealing the least LD50 value (0.672 g/L). In addition, the most toxic compound (coumarin) observed in the current study, deteriorated the growth resulting tremendous reduction (78.39%) in efficacy of conversion of digested food (ECD), and (ECI) efficacy of conversion of ingested food (70.04%) of tenth-instar red palm weevil larvae. The energy-deficient red palm weevil larvae through their intrinsic abilities showed enhanced response to their digestibility resulting 27.78% increase in approximate digestibility (AD) compared to control larvae. The detoxification response of Rhynchophorus ferrugineus larvae determined by the quantitative expression of cytochrome P450, esterases, and glutathione S-transferase revealed enhanced expression among moderately toxic and ineffective compounds. These genes especially cytochrome P450 and GST detoxify the target compounds by enhancing their solubility that leads rapid excretion and degradation resulting low toxicity towards red palm weevil larvae. On the other hand, the most toxic (coumarin) silenced the genes involved in the red palm weevil detoxification mechanism. Based on the toxicity, growth retarding, and masking detoxification activities, coumarin could be a useful future natural red palm weevil-controlling agent.

Specialty oils differ in fatty acid, phytosterol and antioxidant content, impacting their benefits for cardiovascular health. The lipid (fatty acid, phytosterol) and antioxidant (total phenolics, radical scavenging capacity) profiles of grapeseed (GSO), corn (CO) and coconut (CNO) oils and their physiological (triacylglycerides, total and HDL-cholesterol and antioxidant capacity (FRAP) in serum and fatty acid and phytosterol hepatic deposition) and genomic (HL, LCAT, ApoA-1 and SR-BP1 mRNA hepatic levels) responses after their sub-chronic intake (10% diet for 28 days) was examined in healthy albino rats. Fatty acid, phytosterol and antioxidant profiles differed between oils (p ≤ 0.01). Serum and hepatic triacylglycerides and total cholesterol increased (p ≤ 0.01); serum HDL-Cholesterol decreased (p < 0.05); but serum FRAP did not differ (p > 0.05) in CNO-fed rats as compared to CO or GSO groups. Hepatic phytosterol deposition was higher (+2.2 mg/g; p ≤ 0.001) in CO- than GSO-fed rats, but their fatty acid deposition was similar. All but ApoA-1 mRNA level increased in GSO-fed rats as compared to other groups (p ≤ 0.01). Hepatic fatty acid handling, but not antioxidant response, nor hepatic phytosterol deposition, could be related to a more efficient reverse-cholesterol transport in GSO-fed rats as compared to CO or CNO.
Synthetic Aperture Radar Target Recognition with Feature Fusion Based on a Stacked Autoencoder
Authors: Kang Miao , Ji Kefeng , Leng Xiangguang , Xing Xiangwei , Zou Huanxin
Published: January 2017

Feature extraction is a crucial step for any automatic target recognition process, especially in the interpretation of synthetic aperture radar (SAR) imagery. In order to obtain distinctive features, this paper proposes a feature fusion algorithm for SAR target recognition based on a stacked autoencoder (SAE). The detailed procedure presented in this paper can be summarized as follows: firstly, 23 baseline features and Three-Patch Local Binary Pattern (TPLBP) features are extracted. These features can describe the global and local aspects of the image with less redundancy and more complementarity, providing richer information for feature fusion. Secondly, an effective feature fusion network is designed. Baseline and TPLBP features are cascaded and fed into a SAE. Then, with an unsupervised learning algorithm, the SAE is pre-trained by greedy layer-wise training method. Capable of feature expression, SAE makes the fused features more distinguishable. Finally, the model is fine-tuned by a softmax classifier and applied to the classification of targets. 10-class SAR targets based on Moving and Stationary Target Acquisition and Recognition (MSTAR) dataset got a classification accuracy up to 95.43%, which verifies the effectiveness of the presented algorithm.
Entropy-Based Registration of Point Clouds Using Terrestrial Laser Scanning and Smartphone GPS

Published: January 2017

Automatic registration of terrestrial laser scanning point clouds is a crucial but unresolved topic that is of great interest in many domains. This study combines terrestrial laser scanner with a smartphone for the coarse registration of leveled point clouds with small roll and pitch angles and height differences, which is a novel sensor combination mode for terrestrial laser scanning. The approximate distance between two neighboring scan positions is firstly calculated with smartphone GPS coordinates. Then, 2D distribution entropy is used to measure the distribution coherence between the two scans and search for the optimal initial transformation parameters. To this end, we propose a method called Iterative Minimum Entropy (IME) to correct initial transformation parameters based on two criteria: the difference between the average and minimum entropy and the deviation from the minimum entropy to the expected entropy. Finally, the presented method is evaluated using two data sets that contain tens of millions of points from panoramic and non-panoramic, vegetation-dominated and building-dominated cases and can achieve high accuracy and efficiency.
The #nofilter Self: The Contest for Authenticity among Social Networking Sites, 2002–2016
Authors: Salisbury Meredith , Pooley Jefferson
Published: January 2017

This study traces appeals to authenticity, over time, in the promotional material of leading social-networking sites (SNSs). Using the Internet Archive’s Wayback Machine, the public-facing websites of major SNS platforms—beginning with Friendster in 2002—were sampled at six-month intervals, with promotional language and visuals examined for authenticity claims. The authors tracked these appeals, with attention to changes in promotional copy, through to July 2016, among the most popular social media services (as determined by English-language web presence and active monthly user figures or, when unavailable, reported network size). The study found that nearly all SNSs invoked authenticity—directly or through language like “real life” and “genuine”—in their promotional materials. What stood out was the profoundly reactive nature of these claims, with new services often defining themselves, openly or implicitly, against legacy services’ inauthenticity. A recurring marketing strategy, in other words, has been to call out competitors’ phoniness by substituting (and touting) some other, differently grounded mode of authenticity. Since the affordances of social sites, even those touting evanescence or anonymity, make them vulnerable to similar charges, the cycle gets replayed with numbing regularity.
An Emergy-Based Hybrid Method for Assessing Sustainability of the Resource-Dependent Region
Authors: Qu Lulu , Shi Xueyi , Liu Chang , Yuan Ye
Published: January 2017

As the natural resources are getting exhausted, the concept of sustainable development of regions has received increasing attention, especially for resource-dependent cities. In this paper, an innovative method based on emergy analysis and the Human Impact Population Affluence Technology (IPAT) model is developed to analyze the quantitative relationship of economic growth, energy consumption and its overall sustainability level. Taiyuan, a traditional, resource-dependent city in China, is selected as the case study region. The main results show that the total emergy of Taiyuan increased from 9.023 × 1023 sej in 2007 to 9.116 × 1023 sej in 2014, with a 38% decline in non-renewable emergy and an increase of imported emergy up to 125%. The regional emergy money ratio (EMB) was reduced by 48% from 5.31 × 1013 sej/$ in 2007 to 2.74 × 1013 sej/$ in 2014, indicating that the increasing speed of consuming resources and energy was faster than the increase of GDP, and that Taiyuan’s money purchasing power declined. The lower emergy sustainability index (ESI) indicates that Taiyuan was explored and produced large quantities of mineral resources, which puts more stress on the environment as a consequence, and that this is not sustainable in the long run. The IPAT analysis demonstrates that Taiyuan sticks to the efforts of energy conservation and environmental protection. In order to promote regional sustainable development, it is necessary to have an integrated effort. Policy insights suggest that resourceful regions should improve energy and resource efficiency, optimize energy and resourceful structure and carry out extensive public participation.
A Survey of Aflatoxin-Producing Aspergillus sp. from Peanut Field Soils in Four Agroecological Zones of China
Authors: Zhang Chushu , Selvaraj Jonathan , Yang Qingli , Liu Yang
Published: January 2017

Peanut pods are easily infected by aflatoxin-producing Aspergillus sp.ecies from field soil. To assess the aflatoxin-producing Aspergillus sp. in different peanut field soils, 344 aflatoxin-producing Aspergillus strains were isolated from 600 soil samples of four agroecological zones in China (the Southeast coastal zone (SEC), the Yangtze River zone (YZR), the Yellow River zone (YR) and the Northeast zone (NE)). Nearly 94.2% (324/344) of strains were A. flavus and 5.8% (20/344) of strains were A. parasiticus. YZR had the highest population density of Aspergillus sp. and positive rate of aflatoxin production in isolated strains (1039.3 cfu·g−1, 80.7%), the second was SEC (191.5 cfu·g−1, 48.7%), the third was YR (26.5 cfu·g−1, 22.7%), and the last was NE (2.4 cfu·g−1, 6.6%). The highest risk of AFB1 contamination on peanut was in YZR which had the largest number of AFB1 producing isolates in 1g soil, followed by SEC and YR, and the lowest was NE. The potential risk of AFB1 contamination in peanuts can increase with increasing population density and a positive rate of aflatoxin-producing Aspergillus sp. in field soils, suggesting that reducing aflatoxigenic Aspergillus sp. in field soils could prevent AFB1 contamination in peanuts.
Detoxification of Aflatoxin B1 by Zygosaccharomyces rouxii with Solid State Fermentation in Peanut Meal

Published: January 2017

Aflatoxins are highly carcinogenic, teratogenetic, and morbigenous secondary metabolites of Aspergillus flavus and A. parasiticus that can contaminate multiple staple foods, such as peanut, maize, and tree nuts. In this study, Zygosaccharomyces rouxii was screened out and identified from fermented soy paste—one kind of traditional Chinese food—to detoxify aflatoxin B1 (AFB1) by aerobic solid state fermentation in peanut meal. The optimal degradation condition was chosen from single factor experiment, and the most effective detoxification rate was about 97%. As for liquid fermentation, we tested the binding ability of Z. rouxii, and the highest binding rate reached was 74.3% (nonviable cells of Z. rouxii) in phosphate-buffered saline (PBS). Moreover, the biotransformation of AFB1 through fermentation of Z. rouxii in peanut meal was further verified by liquid chromatography/mass spectrometry (LC/MS). According to TIC scan, after fermentation by Z. rouxii, the AFB1 in peanut meal was prominently degraded to the lowering peaks of AFB1. Additionally, m/s statistics demonstrated that AFB1 may be degraded to some new products whose structural properties may be different from AFB1, or the degradation products may be dissolved in the aqueous phase rather than the organic phase. As far as we know, this is the first report indicating that the safe strain of Z. rouxii has the ability to detoxify AFB1.
Barcelona’s New Chinatown: Chinese Strategies in the Housing Market in Barcelona and Globalization
Authors: Martínez-Rigol Sergi , Frago Lluís , Morcuende Alejandro , Carreras Carles , Bernardos Gonzalo
Published: January 2017

Globalization of the urban real estate market, which was originally local, has generated new capital flows worldwide that have reinforced the secondary circuit. Barcelona has not been immune to this process, at least since Spain’s integration into the European Union in 1986. Many legal changes in foreign investment regulations have been introduced in Spain, especially in the housing market. The latest major investments in real estate have been made by former socialist countries, notably the People’s Republic of China and Russia, which both belong to the BRICS group. Chinese localization strategies have been more concentrated. With this theoretical background, the aim of the paper is to analyze the strategies of these recent appropriations of Barcelona’s residential space, in the framework of other economic Chinese investments and in competition with other Mediterranean ports. The main conclusion of this study is related to the definition of arcelona’s Chinatown, its changing location, and processes of social differentiation.
Energy Saving in a Water Supply Network by Coupling a Pump and a Pump As Turbine (PAT) in a Turbopump
Authors: Carravetta Armando , Antipodi Lauro , Golia Umberto , Fecarotta Oreste
Published: January 2017

The management of a water distribution network (WDN) is performed by valve and pump control, to regulate both the pressure and the discharge between certain limits. The energy that is usually merely dissipated by valves can instead be converted and used to partially supply the pumping stations. Pumps used as turbines (PAT) can be used in order to both reduce pressure and recover energy, with proven economic benefits. The direct coupling of the PAT shaft with the pump shaft in a PAT-pump turbocharger (P&P plant) allows us to transfer energy from the pressure control system to the pumping system without any electrical device. Based on experimental PAT and pump performance curves, P&P equations are given and P&P working conditions are simulated with reference to the operating conditions of a real water supply network. The annual energy saving demonstrates the economic relevance of the P&P plant.
Germination responses to current and future temperatures of four seeder shrubs across a latitudinal gradient in western Iberia
Authors: Chamorro Daniel , Luna Belén , Moreno José M.
Published: January 2017

PREMISE OF THE STUDY:

Species differ in their temperature germination niche. Populations of a species may similarly differ across the distribution range of the species. Anticipating the impacts of climate variability and change requires understanding the differential sensitivity to germination temperature among and within species. Here we studied the germination responses of four hard‐seeded Cistaceae seeders to a range of current and future temperatures.

METHODS:

Seeds were collected at sites across the Iberian Peninsula and exposed or not exposed to a heat shock to break dormancy, then set to germinate under four temperature regimes. Temperatures were varied daily and seasonally, simulating the temperature range across the gradient, plus an increased temperature simulating future climate. Time to germination onset and cumulative germination at the end of each season were analyzed for the effects of temperature treatments, seasons, and local climate (temperature of the germination period, Tgp) at each site.

KEY RESULTS:

Tgp was a significant covariate of germination in all species but Cistus populifolius. Temperature treatments significantly affected Cistus ladanifer, C. salviifolius, and Halimium ocymoides. Germination occurred in simulated autumn conditions, with little germination occurring at later seasons, except in unheated seeds of H. ocymoides. Exposure to a heat shock changed the sensitivity to temperature treatments and the relationships with Tgp.

CONCLUSIONS:

Germination responses to temperature differ not only among species but also within species across their latitudinal range. The responses were idiosyncratic and related to the local climate of the population. This germination variability complicates generalizing the impacts of climate variability and climate change.
A postsynthetically 2’-“clickable” uridine with arabino configuration and its application for fluorescent labeling and imaging of DNA
Authors: Walter Heidi-Kristin , Olshausen Bettina , Schepers Ute , Wagenknecht Hans-Achim
Published: January 2017

The arabino-configured analog of uridine with a propargyl group at the 2’-position was synthesized and incorporated into DNA by solid-phase chemistry. The fluorescence quantum yields of DNA strands that were postsynthetically modified by blue and green emitting cyanine-styryl dyes were improved due to the arabino-configured anchor. These oligonucleotides were used as energy transfer donors in hybrids with oligonucleotides modified with acceptor dyes that emit in the yellow-red range. These combinations give energy transfer pairs with blue–yellow, blue–red and green–red emission color changes. All combinations of arabino- and ribo-configured donor strands with arabino- and ribo-configured acceptor strands were evaluated. This array of doubly modified hybrids was screened by their emission color contrast and fluorescence quantum yield. Especially mixed combinations, that means donor dyes with arabino-configured anchor with acceptor dyes with ribo-configured anchor, and vice versa, showed significantly improved fluorescence properties. Those were successfully applied for fluorescent imaging of DNA after transport into living cells.
MID-INFRARED SPECTROSCOPIC OBSERVATIONS OF THE DUST-FORMING CLASSICAL NOVA V2676 OPH*

Published: January 2017

The dust-forming nova V2676 Oph is unique in that it was the first nova to provide evidence of C2 and CN molecules during its near-maximum phase and evidence of CO molecules during its early decline phase. Observations of this nova have revealed the slow evolution of its lightcurves and have also shown low isotopic ratios of carbon (12C/13C) and nitrogen (14N/15N) in its envelope. These behaviors indicate that the white dwarf (WD) star hosting V2676 Oph is a CO-rich WD rather than an ONe-rich WD (typically larger in mass than the former). We performed mid-infrared spectroscopic and photometric observations of V2676 Oph in 2013 and 2014 (respectively 452 and 782 days after its discovery). No significant [Ne ii] emission at 12.8 μm was detected at either epoch. These provided evidence for a CO-rich WD star hosting V2676 Oph. Both carbon-rich and oxygen-rich grains were detected in addition to an unidentified infrared feature at 11.4 μm originating from polycyclic aromatic hydrocarbon molecules or hydrogenated amorphous carbon grains in the envelope of V2676 Oph.
LOG-NORMAL DISTRIBUTION OF COSMIC VOIDS IN SIMULATIONS AND MOCKS
Authors: Russell E. , Pycke J.-R.
Published: January 2017

Following up on previous studies, we complete here a full analysis of the void size distributions of the Cosmic Void Catalog based on three different simulation and mock catalogs: dark matter (DM), haloes, and galaxies. Based on this analysis, we attempt to answer two questions: Is a three-parameter log-normal distribution a good candidate to satisfy the void size distributions obtained from different types of environments? Is there a direct relation between the shape parameters of the void size distribution and the environmental effects? In an attempt to answer these questions, we find here that all void size distributions of these data samples satisfy the three-parameter log-normal distribution whether the environment is dominated by DM, haloes, or galaxies. In addition, the shape parameters of the three-parameter log-normal void size distribution seem highly affected by environment, particularly existing substructures. Therefore, we show two quantitative relations given by linear equations between the skewness and the maximum tree depth, and between the variance of the void size distribution and the maximum tree depth, directly from the simulated data. In addition to this, we find that the percentage of voids with nonzero central density in the data sets has a critical importance. If the number of voids with nonzero central density reaches ≥3.84% in a simulation/mock sample, then a second population is observed in the void size distributions. This second population emerges as a second peak in the log-normal void size distribution at larger radius.

We present results from a deep 2′ × 3′ (comoving scale of 3.7 Mpc × 5.5 Mpc at z = 3) survey at 1.1 mm, taken with the Atacama Large Millimeter/submillimeter Array (ALMA) in the SSA22 field. We observe the core region of a z = 3.09 protocluster, achieving a typical rms sensitivity of 60 μJy beam−1 at a spatial resolution of 0.″7. We detect 18 robust ALMA sources at a signal-to-noise ratio (S/N) > 5. Comparison between the ALMA map and a 1.1 mm map, taken with the AzTEC camera on the Atacama Submillimeter Telescope Experiment (ASTE), indicates that three submillimeter sources discovered by the AzTEC/ASTE survey are resolved into eight individual submillimeter galaxies (SMGs) by ALMA. At least 10 of our 18 ALMA SMGs have spectroscopic redshifts of z ≃ 3.09, placing them in the protocluster. This shows that a number of dusty starburst galaxies are forming simultaneously in the core of the protocluster. The nine brightest ALMA SMGs with S/N > 10 have a median intrinsic angular size of

(

physical kpc at z = 3.09), which is consistent with previous size measurements of SMGs in other fields. As expected, the source counts show a possible excess compared to the counts in the general fields at S
1.1mm ≥ 1.0 mJy, due to the protocluster. Our contiguous mm mapping highlights the importance of large-scale structures on the formation of dusty starburst galaxies.
Swift Detection of a 65 Day X-Ray Period from the Ultraluminous Pulsar NGC 7793 P13

Published: January 2017

NGC 7793 P13 is an ultraluminous X-ray source harboring an accreting pulsar. We report on the detection of a ∼65 day period X-ray modulation with Swift observations in this system. The modulation period found in the X-ray band is P = 65.05 ± 0.10 days and the profile is asymmetric with a fast rise and a slower decay. On the other hand, the u-band light curve collected by Swift UVOT confirmed an optical modulation with a period of P = 64.24 ± 0.13 days. We explored the phase evolution of the X-ray and optical periodicities and propose two solutions. A superorbital modulation with a period of ∼2700–4700 days probably caused by the precession of a warped accretion disk is necessary to interpret the phase drift of the optical data. We further discuss the implication if this ∼65 day periodicity is caused by the superorbital modulation. Estimated from the relationship between the spin-orbital and orbital-superorbital periods of known disk-fed high-mass X-ray binaries, the orbital period of P13 is roughly estimated as 3–7 days. In this case, an unknown mechanism with a much longer timescale is needed to interpret the phase drift. Further studies on the stability of these two periodicities with a long-term monitoring could help us to probe their physical origins.

Background

GS-9256 is an inhibitor of HCV NS3 protease with a macrocyclic structure and novel phosphinic acid pharmacophore.

Methods

Key preclinical properties of GS-9256 including in vitro antiviral activity, cross-resistance and pharmacokinetic properties were investigated in non-human species.

Results

In genotype (GT) 1b Huh-luc cells with a replicon encoding luciferase, GS-9256 had a mean 50% effective concentration (EC50) value of 20.0 nM, with minimal cytotoxicity. Antiviral activity was similar in a number of additional GT1b and GT1a replicon cell lines. Similar potency was observed in chimeric replicons encoding the NS3 protease of GT1 clinical isolates. GS-9256 was less active in GT2a replicon cells (14.2-fold increase in EC50). Additive to synergistic in vitro antiviral activity was observed when GS-9256 was combined with other agents including interferon-α, ribavirin, NS5B polymerase inhibitors GS-6620 and tegobuvir, as well as the NS5A inhibitor ledipasvir. GS-9256 retained wild-type activity against all tested NS5B and NS5A inhibitor resistance mutations. GS-9256 was metabolically stable in microsomes and hepatocytes of tested species, including rodents, dogs and humans. GS-9256 had high bioavailability in mice (near 100%) and moderate bioavailability in rats (14%), dogs (21%) and monkeys (14%). Elimination half-lives were approximately 2 h in mice, 0.6 h in rats, 5 h in dogs and 4 h in monkey. A study in bile duct-cannulated rats indicated that the major route of elimination is through biliary excretion of unmetabolized GS-9256.

Conclusions

GS-9256 showed a favourable preclinical profile supportive of clinical development for the treatment of chronic HCV infection in GT1 patients.
Edoardo Weiss, le « tenace pionnier » de la psychanalyse italienne
Authors: Corsa Rita , Riva Elena
Published: January 2017

L’auteur décrit le personnage d’Edoardo Weiss (Trieste, 1889 – Chicago, 1970), psychiatre et psychanalyste d’origine juive qui introduit et fit connaître la psychanalyse en Italie en se heurtant à l’hostilité des milieux médico-scientifiques, religieux et politiques. Il fut le seul psychanalyste du petit groupe de médecins qui fondèrent la Société psychanalytique italienne (à Teramo, en 1925) et réorganisèrent cette même Société en 1932, à Rome. En 1939, à la suite des lois raciales promulguées l’année précédente, Weiss quitta l’Italie pour se réfugier aux États-Unis, avec sa femme Vanda Shrenger (pédiatre et psychanalyste) et leurs deux fils. Ses études consacrées aux troubles du Moi dans certaines pathologies graves et ses articles pionniers concernant l’asthme bronchique et l’agoraphobie demeurent son legs théorique principal. Pour documenter la reconstruction historique, l’auteur se base sur des documents inédits des Archives et la précieuse correspondance entre Edoardo Weiss et son ancien analyste, Paul Federn.
Narcissisme, reconnaissance psychique et validation affective
Authors: Borgogno Franco , Adam Elena
Published: January 2017

En se remémorant sa participation à un séminaire de groupe avec Herbert Rosenfeld et à partir de cette expérience, l’auteur décrit et commente l’approche tardive de ce dernier dans le travail avec des patients souffrant gravement sur le plan narcissique. À travers l’analyse détaillée de la supervision d’une séance avec un patient psychotique, cette communication met surtout en exergue l’importance de la construction – au niveau cognitif et affectif – d’un terrain commun, afin de pouvoir procéder ensuite à des interprétations du transfert. Cet article met notamment en lumière les éléments qui favorisent la création de ce terrain cognitivo-affectif qui est nécessaire pour pouvoir faire le lien – de manière profitable au patient – entre les séquences relationnelles racontées et agies par le patient avec le hic et nunc des interactions analytiques en cours de séance.
Plaisir, maîtrise et légitimation narcissique, points cardinaux de la perversion
Authors: Bolognini Stefano , Dujarry Corinne
Published: January 2017

Au-delà du concept de perversion entendu comme une forme strictement sexuelle au sens concret, on préfère aujourd’hui en étendre le sens à l’aire relationnelle interne et externe tout entière, une aire qui maintient une continuité de sens et de fonction (« perversion relationnelle ») avec la sexualité. Sont ici présentés les concepts de maîtrise/savoir-faire, fonction légitimante, prestige secret et de surexcitation érotisante, dans un cadre socioculturel ainsi que dans une séquence clinique.
Trauma et souffrance psychique des premières expériences de vie
Authors: Cancrini Tonia , Adam Elena
Published: January 2017

Ce travail se confronte au problème du trauma et de la douleur, et se focalise en particulier sur les traumas vécus au cours de l’enfance en examinant les premiers rapports de l’enfant et de sa mère, et en soulignant leur importance pour le développement affectif et mental de l’enfant. C’est la présence de parents et d’adultes fiables qui permet aux enfants de se développer harmonieusement. Lors de ces expériences traumatiques, l’auteur souligne l’importance de la mémoire, de la remémoration des vécus occultés et lointains. Deux cas cliniques sont présentés : un garçon dont la mère a subi un très grave trauma durant sa grossesse et une fillette adoptée au passé tragique, qui mettent en lumière la fonction fondamentale de la psychanalyse lors de sa confrontation au vécu du trauma.
Freud et le vin
Authors: Kamieniak Jean-Pierre
Published: January 2017

Si tous les auteurs s’accordent à reconnaître que la problématique alcoolique est quantité négligeable dans l’œuvre du savant viennois, une investigation de la nature du lien que l’homme Freud a pu entretenir avec le vin met en évidence, à notre grande surprise, que l’usage et le recours à ce dernier ont rendu possibles les découvertes intimes qui président aux fondements de la science nouvelle. Dès lors, sous l’effet du refoulement, l’appétence du gourmet fera place à l’intolérance, conformément à ce « renversement d’affect » dont il fut le découvreur.

Réflexions sur la notion de nature à l’âge classique
Authors: Cléro Jean-Pierre
Published: January 2017

Les mathématiques jouent un double rôle dans la physique moderne. Elles permettent de construire les phénomènes en les organisant selon des lois, lesquelles sortent de leur domaine juridique pour prétendre devenir celles du système de la nature. L’effet de sidération de la coïncidence des mathématiques avec les phénomènes atteint son apothéose avec Newton, à la gloire du théisme ; mais il fut de courte durée. On découvre alors un second rôle, sceptique, des mathématiques, qui vient rigoureusement saper la certitude que l’on s’apprêtait à donner aux lois, en la fractionnant et en lui assignant des degrés. La nature devient alors ce que le mathématicien conjecture, avec des chances d’avoir raison ou d’avoir tort, et ce qu’il se donne le droit de conjecturer de l’organisation des phénomènes. La conception théiste se dissout dans les chances qu’il s’agit de déterminer et qui ne s’appliquent plus que de façon réflexive aux phénomènes.
Le silence de la musique dans The Wanderer de Frances Burney
Authors: Dubois Pierre
Published: January 2017

Les héroïnes de Frances Burney se réfugient souvent dans un silence volontaire qui contribue à une définition de leur féminité : souvent contrainte de se taire dans la société d’alors, la femme s’arroge dialectiquement le pouvoir du silence pour contester la violence (masculine) de la société. Dans The Wanderer (1814), dernier roman de Burney, l’héroïne Juliet, femme errante et musicienne exceptionnelle, érige son silence en une esthétique et sa musique apparaît comme une modalité possible du silence. Par son silence verbal comme par sa musique, Juliet établit un espace pour se retrouver en elle-même. Son silence musicalisé la protège et la refonde. Dans ce long roman bavard et prolixe, « faire silence » permet d’activer un principe esthétique de contraste, de rupture et d’écart.
« Faire silence » dans l’emblématique chrétienne de l’époque moderne : quelques exemples chez Geffrey Whitney, Henry Peacham et Francis Quarles
Authors: Chardin Jean-Jacques
Published: January 2017

Faire silence implique que le silence est imposé, souvent à soi-même, pour congédier le discours stérile et faire affleurer la parole intérieure. Dans l’emblématique anglaise chrétienne du début du xviie siècle, le silence est d’abord montré par des images souvent tirées du fonds culturel de l’Antiquité et qui empruntent à l’éloquence classique plusieurs de ses parties (inventio, dispositio, actio…) Ainsi les images travaillent-elles les émotions de celui qui les regarde. Le silence s’exprime aussi, paradoxalement, par les gloses poétiques, parfois longues comme dans les Hieroglyphikes de Quarles (1638), mais qui refusent pourtant la grande ostentation oratoire à la manière de Cicéron pour privilégier une rhétorique laconique, coupée et brève, à l’imitation de Sénèque ou de Tacite. Images et textes se conjuguent alors pour faire de l’emblème un exercice de méditation silencieuse par lequel l’orant entre en communication avec le divin.

Authors: Maity Kalipada , Pradhan Swastik
Published: January 2017

Titanium alloy is having a widespread application in the field of aerospace, marine and automobile industries. However, its machining is still a challenging task for the manufacturing industries due to the chemical reactivity and poor thermal conductivity properties. In this study, machining of titanium alloy (Ti-6Al-4V) was carried out with WM25CT cutting inserts. The effects of cutting speed, feed and depth of cut on cutting force, surface roughness, chip-reduction coefficient and flank wear of the cutting tool were analyzed. The response surface methodology (RSM) approach with central composite design and face centered was used to carry out the experimentation. The second order quadratic equations were developed and compared with the experimented data sets. From the analysis of the chip morphology, it was observed that side flow of chips and gap between the lamella of the chips varied with respect to the change in the process parameters. The type of chip produced also varied according to the variation of the process parameters. Severe nose damage was observed at cutting speed 160 m/min, feed 0.14 mm/rev, depth of cut 0.75 mm. Due to this snarled ribbon type of chips were produced in place of occurrence of the serration in the chips.

Objetivou-se identificar a prevalência referida de hipertensão arterial e os fatores de risco; e levantar as práticas de controle entre idosos adscritos a uma Estratégia Saúde da Família de Teresina, Piauí, Brasil. Estudo descritivo, transversal, quantitativo, realizado de maio a julho de 2014, com 126 idosos, mediante entrevista domiciliar. Utilizaram-se estatística descritiva e o teste Qui-Quadrado para verificar as associações, com nível de significância de p<0,05. A idade média foi de 70 anos (±8,0), maioria mulheres (69,8%), com ensino fundamental (58,8%) e baixa renda familiar (51,6%). A prevalência referida de hipertensão arterial foi de 63,5%. Encontrou-se associação estatística entre a prevalência de hipertensão arterial e as variáveis idade (p=0,021) e ter trabalho remunerado (p=0,004). A principal prática de controle referida foi o uso de medicamentos anti-hipertensivos, mas 16,2% com uso irregular. A prevalência encontrada foi elevada e os resultados evidenciaram as dificuldades de adesão ao tratamento medicamentoso e às outras práticas de tratamento, o que requer atenção especial por parte dos profissionais, em especial do enfermeiro.

Published: January 2017

Os Distúrbios Osteomusculares Relacionados ao Trabalho (DORT) são doenças crônicas causadas pelo trabalho extenuante, sem pausas, com posturas incorretas e movimentos repetitivos. Estudos mostram que portadores de doenças crônicas tendem a ter uma baixa qualidade de vida. Sendo assim, o objetivo desta pesquisa foi analisar a percepção da qualidade de vida de portadores de DORT no Estado de Sergipe, Brasil. A amostra foi composta por 17 trabalhadores aludidos nos Centros de Referência em Saúde do Trabalhador do referido estado, no ano de 2013, os quais foram voluntários e responderam a um roteiro de entrevista elaborada pelos autores da pesquisa, e gravadas em áudio. Os resultados foram categorizados e descritos através da análise de conteúdo, o que permitiu a observação de que todos os aspectos de qualidade de vida demonstraram-se negativos. Considera-se que os trabalhadores avaliados nesta pesquisa possuem uma percepção negativa da qualidade de vida, o que influencia, também negativamente, no processo saúde e doença dos indivíduos.

O puerpério é um período complexo, vivido e percebido de forma singular pela mulher, no qual a assistência profissional deve ser pautada no cuidado integral, fundamentado em seu contexto sociocultural. O objetivo deste estudo foi avaliar possíveis associações da 'prática do autocuidado' referida pela mulher com indicadores sociodemográficos e com as exigências propostas na Teoria de Orem (universais, de desenvolvimento e de desvio de saúde), no primeiro ano pós-parto. Trata-se de um estudo transversal, aninhado em uma coorte prospectiva, realizado em um município do sul do Brasil, tendo como amostra 310 puérperas. A coleta de dados foi feita mediante aplicação de um formulário semiestruturado, em visitas domiciliares. Na análise estatística foi utilizado o Teste Qui-quadrado (p<0,05). A 'prática do autocuidado' se associou aos seguintes itens: faixa etária (p=0,043); renda (p=0,045); apoio do governo (p=0,025); percepção do que é cuidar de si (p=0,042); ingestão de frutas (p=0,039); sono (p=0,005); práticas (p=0,039) e frequência do lazer (p=0,037); retorno aos estudos (p=0,036); autopercepção de doença depressiva (p=0,005); tipo de parto (p=0,038), laceração e/ou episiorrafia (p=0,046). Os resultados identificaram que a prática do autocuidado pela mulher sofreu influências de sua idade, disponibilidade de recursos financeiros e de alguns determinantes presentes nas três exigências da Teoria de Orem.

Authors: Shrivastava Deepika , Sanyal Sankar P.
Published: January 2017

The structural, electronic and elastic properties of CeTl with CsCl-type B2 structure have been investigated using full-potential linearized augmented plane wave (FP-LAPW) method based on density functional theory (DFT) within the generalized gradient approximation (GGA) for exchange and correlation potential. The ground state properties such as lattice constant, bulk modulus and pressure derivative of bulk modulus have been calculated which are in good agreement with available experimental data. The band structure and density of state depict that 4f electrons of Ce element have dominant character in electronic conduction and are responsible for metallic character of CeTl. The charge density plot reveals that the metallic as well as ionic bonding exist between Ce and Tl atoms. The calculated elastic constants indicate that CeTl is mechanically stable in cubic B2 phase and found to be ductile in nature.

Fifty shades of African lightness: a bio-psychosocial review of the global phenomenon of skin lightening practices
Authors: Jacobs Meagan , Levine Susan , Abney Kate , Davids Lester
Published: January 2017

Skin-lightening is an aesthetic practice of global concern. By adopting a biopsycho-social approach, we consider the interplay between the biological, psychological and social factors that underpin the circulation and consumption of skin lighteners in South Africa. This paper reflects on biological aspects of skin lightening, interpersonal relationships, individual beliefs and expectations about the maintenance of health and well being that informs cosmetic practices. The paper seeks to examine claims made by historians (Thomas) and political philosophers and activists (Biko) that colonialism and apartheid in South Africa historically reinforced the use of skin lightening products in the country. The paper also investigates the role of media in staking out the boundaries of beauty. We argue that men and women practice skinlightening not only as a complex result of the internalization of global standards of beauty, but meshed with a national politics of race and colorism. Banning skin lightening products without understanding the biological effects but also the social forces that underlie their increased popularity will prove futile. Moreover, we must consider the immeasurable pleasures associated with lightening, and the feelings with achieving visibility in South Africa, a country that continues to wrestle with blackness.

Authors: Mbemba Gisèle Irène Claudine , Gagnon Marie-Pierre , Hamelin-Brabant Louise
Published: January 2017

Shortage of healthcare workers in rural and remote areas remains a growing concern both in developed and developing countries. This review aims to synthesize the significant factors impacting healthcare professionals’ recruitment and retention in rural and remote areas, and to identify those relevant for developing countries. This paper included the following steps: exploring scientific literature through predetermined criteria and extracting relevant information by two independents reviewers. The AMSTAR tool was used to assess the methodological quality. Of the 224 screened publications, 15 reviews were included. Four reviews focused on recruitment factors, and another four reviews focused on retention factors. The remaining focused both on recruitment and retention factors. The most important factors influencing recruitment were rural background and rural origin, followed by career development. Opportunities for professional advancement, professional support networks and financial incentives were factors impacting retention. While the main factors influencing recruitment and retention have been largely explored in the literature, the evidence on strategies to reduce the shortage of healthcare workers in rural area, particularly in developing countries, is low. Further research in this field is needed.
