Presencia y estereotipos de grupos étnicos en los anuncios de prensa en Panamá Años 1998, 2008 y 2018
Authors: Wang Tiffany
Published: February 2020

La investigación se enfoca en la presencia y los estereotipos que tienen los distintos grupos étnicos y cómo son proyectados en la publicidad panameña. El objetivo principal es evaluar la función que se le asigna a estos grupos en la publicidad impresa en los periódicos panameños y si son representados en roles que reiteran en los estereotipos. Se hizo una integración de métodos cuantitativos y cualitativos. Se realizó un análisis de contenido contabilizando la presencia de los grupos étnicos en la publicidad impresa en 360 ejemplares de los cuatro periódicos más populares de Panamá en tres décadas. Posteriormente, se entrevistaron seis directores creativos, quienes nos amplían el tema del uso de diversidad étnica en la publicidad en Panamá. La principal conclusión es que el grupo étnico que predomina en los avisos de prensa de Panamá son los blancos con 60.8%, mientras que los mestizos tienen un cuarto de representación. Los afrodescendientes están presentes en 9.9% de la publicidad. Los grupos menos representados son los indígenas y los asiáticos con 1.4% y 1.1% de presencia respectivamente. Estas cifras en la publicidad no reflejan la realidad de distribución demográfica panameña. También se demostró que la participación de los grupos étnicos en la publicidad de los anuncios de prensa en Panamá, sí depende de la categoría y el nivel de prestigio del producto o servicio ofrecido por el anunciante.

A moral crisis is a precarious condition in a society or group in which there is a deterioration or damage to actions, attitudes, morals and character. This moral crisis is seen in Indonesian society, both among young people, even parents and even small children. This moral crisis is indicated by the proliferation of acts that approach adultery or even adultery, the culture of smoking or even illegal drugs and intoxicants (khamr). In addition, the existence of a community that is disturbing the community or even criminal and brutal acts that have mushroomed in the community has also triggered a moral crisis. Not only that, but there are still many more indications of a moral crisis found in society.

Krisis moral adalah suatu kondisi genting dalam suatu masyarakat atau kelompok yang mana terjadinya kemerosotan atau kerusakan perbuatan, sikap, akhlak dan budi pekerti. Krisis moral ini terlihat di dalam masyarakat Indonesia, baik itu pada kalangan pemuda, orang tua bahkan kalangan anak kecil sekali pun. Krisis moral ini terindikasi dengan maraknya perbuatan yang mendekati zina atau bahkan zina, kebudayaan merokok atau bahkan obat-obatan terlarang dan minuman memabukkan (khamr). Selain itu juga adanya komunitas yang meresahkan masyarakat atau bahkan tindak kriminal dan brutal yang menjamur di masyarakat juga memicu adanya krisis moral. Tidak hanya itu, namun masih banyak lagi indikasi krisis moral yang terdapat di dalam masyarakat.

Understanding nanoparticle flow with a new in vitro experimental and computational approach using hydrogel channels

Published: February 2020

Nanoparticles (NPs) are considered as one of the most promising drug delivery vehicles and a next-generation solution for current medical challenges. In this context, variables related to flow of NPs such as the quantity of NPs lost during transport and flow trajectory greatly affect the clinical efficiency of NP drug delivery systems. Currently, there is little knowledge of the physical mechanisms dominating NP flow inside the human body due to the limitations of available experimental tools for mimicking complex physiological environments at the preclinical stage. Here, we report a coupled experimental and computational fluid dynamics (CFD)-based novel in vitro approach to predict the flow velocity and binding of NP drug delivery systems during transport through vasculature. Poly(hydroxyethyl)methacrylate hydrogels were used to form soft cylindrical constructs mimicking vascular sections as flow channels for synthesized iron oxide NPs in these first-of-its-kind transport experiments. Brownian dynamics and material of the flow channels played key roles in NP flow, based on the measurements of NP flow velocity over seven different mass concentrations. A fully developed laminar flow of the NPs under these conditions was simultaneously predicted using CFD. Results from the mass loss of NPs during flow indicated a diffusion-dominated flow at higher particle concentrations but a flow controlled by the surrounding fluid and Brownian dynamics at the lowest NP concentrations. The CFD model predicted a mass loss of 1.341% and 6.253% for the 4.12 g·mL−1 and 2.008 g·mL−1 inlet mass concentrations of the NPs, in close confirmation with the experimental results. This further highlights the reliability of our new in vitro technique in providing mechanistic insights of NP flow for potential preclinical stage applications.
The use of isoxazoline and isoxazole scaffolding in the design of novel thiourea and amide liquid-crystalline compounds
Authors: Gonçalves Itamar L , da Rosa Rafaela R , Eifler-Lima Vera L , Merlo Aloir A
Published: February 2020

A series of novel thiourea and amide liquid crystals containing 5-membered isoxazoline and isoxazole rings were synthetized and the liquid crystal properties studied. Thioureas were obtained using a condensation reaction of benzoyl chlorides, arylamines and ammonium thiocyanate. The amides, on the other hand, were the byproduct of a quantitative reaction which used potassium cyanate as the starting material. Thiourea and amide derivatives were predominantly SmA mesophase inductors. A nematic mesophase was observed only for thioureas and amides containing an isoxazole ring. Additionaly, the liquid crystal behavior was also dependent on the relative position of nitrogen and oxygen atoms on the 5-membered heterocycle.

We present the analysis of the microlensing event OGLE-2016-BLG-1227. The light curve of this short-duration event appears to be a single-lens event affected by severe finite-source effects. Analysis of the light curve based on a single-lens single-source (1L1S) model yields very small values of the event timescale,

days, and the angular Einstein radius,

mas, making the lens a candidate of a free-floating planet. Close inspection reveals that the 1L1S solution leaves small residuals with an amplitude of ΔI ≲ 0.03 mag. We find that the residuals are explained by the existence of an additional widely separated heavier lens component, indicating that the lens is a wide-separation planetary system rather than a free-floating planet. From Bayesian analysis, it is estimated that the planet has a mass of

and it is orbiting a low-mass host star with a mass of

located with a projected separation of

au. The planetary system is located in the Galactic bulge with a line-of-sight separation from the source star of

kpc. The event shows that there is a range of deviations in the signatures of host stars for apparently isolated planetary lensing events and that it is possible to identify a host even when a deviation is subtle.

We report the discovery of WISE 2150-7520AB (W2150AB): a widely separated (∼341 au) very low-mass L1 + T8 co-moving system. The system consists of the previously known L1 primary 2MASS J21501592-7520367 and a newly discovered T8 secondary found at position 21:50:18.99–75:20:54.6 (MJD = 57947) using Wide-field Infrared Survey Explorer data via the Backyard Worlds: Planet 9 citizen science project. We present Spitzer ch1 and ch2 photometry (ch1–ch2 = 1.41 ± 0.04 mag) of the secondary and Folded-port InfraRed Echellette prism spectra of both components. The sources show no peculiar spectral or photometric signatures, indicating that each component is likely field age.

Evidence for a Multipolar Magnetic Field in SGR J1745-2900 from X-Ray Light-curve Analysis
Authors: de Lima Rafael C. R. , Coelho Jaziel G. , Pereira Jonas P. , Rodrigues Claudia V. , Rueda Jorge A.
Published: February 2020

SGR J1745-2900 was detected from its outburst activity in 2013 April and it was the first soft gamma repeater (SGR) detected near the center of the Galaxy (Sagittarius A*). We use 3.5 yr Chandra X-ray light-curve data to constrain some neutron star (NS) geometric parameters. We assume that the flux modulation comes from hot spots on the stellar surface. Our model includes the NS mass, radius, a maximum of three spots of any size, temperature and positions, and general relativistic effects. We find that the light curve of SGR J1745-2900 could be described by either two or three hot spots. The ambiguity is due to the small amount of data, but our analysis suggests that one should not disregard the possibility of multi-spots (due to a multipolar magnetic field) in highly magnetized stars. For the case of three hot spots, we find that they should be large and have angular semiapertures ranging from 16° to 67°. The large size found for the spots points to a magnetic field with a nontrivial poloidal and toroidal structure (in accordance with magnetohydrodynamics investigations and Neutron Star Interior Composition Explorer’s (NICER) recent findings for PSR J0030+0451) and is consistent with the small characteristic age of the star. Finally, we also discuss possible constraints on the mass and radius of SGR J1745-2900 and briefly envisage possible scenarios accounting for the 3.5 yr evolution of SGR J1745-290 hot spots.
Two New Outbursts and Transient Hard X-Rays from 1E 1048.1-5937

Published: February 2020

Since its discovery, 1E 1048.1−5937 has been one of the most active magnetars, both in terms of radiative outbursts, and changes to its spin properties. Here we report on a continuing monitoring campaign with the Neil Gehrels Swift Observatory X-ray Telescope in which we observe two new outbursts from this source. The first outburst occurred in 2016 July, and the second in 2017 December, reaching peak 0.5–10 keV absorbed fluxes of

erg s−1 cm−2 and

erg s−1 cm−2, respectively, factors of ∼5 and ∼4 above the quiescent flux. Both new outbursts were accompanied by spin-up glitches with amplitudes of

Hz and

Hz, respectively. Following the 2016 July outburst, we observe, as for past outbursts, a period of delayed torque fluctuations, which reach a peak spin-down of 1.73 ± 0.01 times the quiescent rate, and which dominates the spin evolution compared to the spin-up glitches. We also report an observation near the peak of the first of these outbursts with NuSTAR in which hard X-ray emission is detected from the source. This emission is well characterized by an absorbed blackbody plus a broken power law, with a power-law index above 13.4 ± 0.6 keV of

, similar to those observed in both persistent and transient magnetars. The hard X-ray results are broadly consistent with models of electron/positron cooling in twisted magnetic field bundles in the outer magnetosphere. However, the repeated outbursts and associated torque fluctuations in this source remain puzzling.
The Roles of Mass and Environment in the Quenching of Galaxies. II.

Published: February 2020

We take advantage of an analytic model of galaxy formation coupled to the merger tree of an N-body simulation to study the roles of environment and stellar mass in the quenching of galaxies. The model has been originally set in order to provide the observed evolution of the stellar mass function as well as reasonable predictions of the star formation rate–stellar mass relation, from high redshift to the present time. We analyze the stellar mass and environmental quenching efficiencies and their dependence on stellar mass, halo mass (taken as a proxy for the environment), and redshift. Our analysis shows that the two quenching efficiencies are dependent on redshift and stellar and halo mass, and that the halo mass is also a good proxy for the environment. The environmental quenching increases with decreasing redshift and is inefficient below log M
* ∼ 9.5, reaches the maximum value at log M
* ∼ 10.5, and decreases again, becoming poorly efficient at very high stellar mass (log M
* ≳ 11.5). Central and satellites galaxies are mass quenched differently: for the former, the quenching efficiency depends very weakly on redshift but strongly on stellar mass; for the latter, it strongly depends on both stellar mass and redshift in the range

. According to the most recent observational results, we find that the two quenching efficiencies are not separable: intermediate-mass galaxies, as well as intermediate/massive galaxies in more massive halos, are environmentally quenched faster. At stellar masses lower than log M
* ≲ 9.5, both quenching mechanisms become inefficient, independently of the redshift.

Understanding the physical processes in the solar wind and corona that actively contribute to heating, acceleration, and dissipation is a primary objective of NASA’s Parker Solar Probe (PSP) mission. Observations of circularly polarized electromagnetic waves at ion scales suggest that cyclotron resonance and wave–particle interactions are dynamically relevant in the inner heliosphere. A wavelet-based statistical study of circularly polarized events in the first perihelion encounter of PSP demonstrates that transverse electromagnetic waves at ion resonant scales are observed in 30–50% of radial field intervals. Average wave amplitudes of approximately 4 nT are measured, while the mean duration of wave events is on the order of 20 s; however, long-duration wave events can exist without interruption on hour-long timescales. Determination of wave vectors suggests propagation parallel/antiparallel to the mean magnetic field. Though ion-scale waves are preferentially observed during intervals with a radial mean magnetic field, we show that measurement constraints, associated with single spacecraft sampling of quasi-parallel waves superposed with anisotropic turbulence, render the measured coherent ion-wave spectrum unobservable when the mean magnetic field is oblique to the solar wind flow; these results imply that the occurrence of coherent ion-scale waves is not limited to a radial field configuration. The lack of radial scaling of characteristic wave amplitudes and duration suggests that the waves are generated in situ through plasma instabilities. Additionally, observations of proton distribution functions indicate that temperature anisotropy may drive the observed ion-scale waves.
Detection and quantification of Campylobacter spp. in Brazilian poultry processing plants

Published: February 2020

Introduction: Campylobacteriosis is considered the most common bacteria-caused human gastroenteritis in the world. Poultry is a major reservoir of Campylobacter. Human infection may occur by consumption of raw and undercooked poultry or by contamination of other foods by these items. The aim of this study was to assess the prevalence of Campylobacter spp. in poultry processing plants with conventional culture method and real-time PCR.

Methodology: A total of 108 poultry processing plant samples were collected to test with conventional microbiology and qPCR. Sampling included cloacal swabs, swabs of transport crates (before and after the cleaning and disinfection process) and carcasses (after the chiller, cooled at 4°C and frozen at −12°C).

Results: Positivity in cloacal swabs indicated that poultry arrived contaminated at the slaughterhouse. Contamination in transport cages was substantially increased after the cleaning process, indicating that the process was ineffective. The detection of Campylobacter on carcasses was higher than that on cloacal swabs, which could indicate cross-contamination during the slaughtering process. Conventional microbiology and molecular methods revealed a prevalence of 69.4% and 43.5%, respectively. Lower detection by qPCR can be attributed to the high specificity of the kit and to biological components that could inhibit PCR reactions.

Conclusions: Our results indicate that poultry arrive contaminated at the slaughterhouse and that contamination can increase during the slaughtering process due to cross-contamination. The isolation of Campylobacter in cooled and frozen carcasses corroborates the bacterial survival even at temperatures considered limiting to bacterial growth which are routinely used for food preservation.

Sphaenorhynchus canga foi registrado em sete novas localidades de corpos d’água lênticos, tanto naturais quanto antrópicos (pequenas represas), em áreas de campo rupestre ferruginoso e floresta estacional semidecidual antropizada. Como a descrição da espécie baseou-se apenas em machos, apresenta-se a morfometria das fêmeas analisadas, que se apresentaram maiores que machos. Seis localidades situam-se externamente aos limites da Chapada de Canga, mas S. canga continua sendo endêmico do Quadrilátero Ferrífero. São discutidos possíveis padrões de distribuição de S. canga e a influência da distribuição geográfica conhecida e da plasticidade ecológica sobre ameaças à espécie.
Ni race, ni classe ?

Qualifiée de « vaste zone d’éducation prioritaire » par l’Inspection générale, la Polynésie française est à la fois comparable à la métropole dans la structuration et les finalités de son système scolaire, et dissemblable quant à l’ampleur des difficultés rencontrées par ses élèves. Cet article se penche sur les enjeux de la mobilisation d’une « différence culturelle » pour expliquer cet écart, faisant l’hypothèse que c’est la prégnance d’un culturalisme occulte qui se joue vraiment à l’école. Il interroge le décalage entre une vision officiellement color-blind (c’est-à-dire indifférente à l’origine ethno-raciale) et la réalité de la perception des discriminations.
Les enfants otages d’une séparation parentale conflictuelle : quel impact sur leur psychisme ? Regards cliniques sur 10 ans de pratique du groupe thérapeutique en équipe SOS enfants
Authors: Garbar Stéphanie , Plennevaux Virginie
Published: February 2020

En 2019, cela fait 11 ans que notre premier groupe thérapeutique -destiné aux enfants pris dans une séparation parentale conflictuelle - a vu le jour. Ces années nous font mesurer à quel point la violence des dynamiques conflictuelles a un impact délétère sur le psychisme des enfants. En effet, les conflits entre les parents génèrent une réelle violence pour les enfants et constituent ainsi une maltraitance psychologique. Dans un premier temps, nous décrivons le cadre d’intervention du travail de groupe, que nous garantissons par cinq niveaux de contenance. Cette première partie nous permet par ailleurs de définir notamment les outils cliniques utilisés pour soutenir ce cadre. La seconde partie s’attarde sur nos observations cliniques, en lien avec des concepts psychanalytiques, de l’impact de ces conflits sur les enfants. Pour cela, nous proposons aux lecteurs de détailler cinq profils psycho-affectifs et relationnels d’enfants que nous avons déterminés en fonction des mécanismes de défense que ceux-ci mettent en place face à l’angoisse que provoque le conflit massif entre leurs parents. Nous proposons, pour chaque profil, une illustration du type de production créative que ces enfants réalisent. Ces illustrations montrent la violence des interactions qu’ils rencontrent dans leur famille, et la dynamique psychique et relationnelle dans laquelle ils fonctionnent. En conclusion, nous proposons quelques perspectives de réflexion autour de ces situations complexes.
Le défi de l’adoption de l’allaitement maternel exclusif au Burkina Faso
Authors: Arcens Somé Marie Thérèse
Published: February 2020

Introduction : L’OMS et l’UNICEF font de l’allaitement maternel exclusif une des pratiques essentielles à la lutte contre la mortalité néonatale. Les deux organismes internationaux ont mis au point une formation de 40 heures sur le conseil en allaitement, en vue d’apprendre à un corps de soignants à apporter une assistance qualifiée aux mères allaitantes et à les aider à surmonter les difficultés. Cependant, dans les maternités comme celles de la région de la boucle du Mouhoun où l’étude a eu lieu, bien qu’un ensemble de recommandations techniques soient globalement adoptées, l’allaitement maternel exclusif se fraye difficilement un chemin dans les habitudes des mères. Cette étude a pour objectif d’examiner les blocages existant à la maternité et dans les familles, qui empêchent la pratique de l’allaitement maternel exclusif de se généraliser. Méthode : L’approche qualitative a été utilisée à travers des entretiens ouverts avec différentes catégories de professionnels de santé et des membres des communautés. Nous avons effectué 38 entretiens avec le personnel de santé et administratif, et 9 entretiens avec des guérisseurs employant des savoirs traditionnels. Dans les maternités, 14 observations ont été réalisées auprès de la mère et de ses accompagnants. Aussi, 24 observations ont été réalisées sur la prise en charge du nouveau-né à domicile. Résultats : Les résultats de l’étude montrent que l’allaitement exclusif s’avère compliqué à mettre en œuvre, notamment à cause de l’utilisation de plantes médicinales sous forme de lavage et de gavage par les familles. De plus, les sages-femmes ne donnent pas les informations aux mères au moment approprié. Conclusion : Nous suggérons que les informations clés soient données aux mères à la dernière visite prénatale et non plus dans les minutes qui suivent l’accouchement.

Published: February 2020

SPC (Statistical Process Control) is one of the Lean Manufacturing techniques, but especially Six Sigma, being a method of improving the quality of the manufacturing process, which allows the identification of errors before their production, with the help of which a process can be supervised and when needed, it is possible to carry out an intervention of regulation, respectively of correction of the process, before being nonconformities. The paper presents a study regarding the use of SPC at a company in the automotive field in order to improve the quality of the manufacturing process for a knuckle. Thus, a number of 25 samples were taken, each sample containing a number of 5 pieces. After sampling, a series of techniques and statistical data were used, respectively diagrams and control sheets, which allowed the determination of the process capability by using MiniTab software.
3D Curve Generation Using Spherical Polar Piecewise Interpolation in CAD and CAM
Authors: Dupac Mihai
Published: February 2020

In this paper a newly 3D path planning approach and curve generation for design and manufacturing efficiency is considered. The 3D path is generated by a combination of piecewise interpolating curves - along a given number of via-points - created via a spherical coordinate system specified by the polar angles, radial distances and the associated azimuthal angles. Each piecewise interpolating curve is constructed using Hermite polar interpolation in the projective polar plane and the rotating azimuthal plane. To verify the proposed approach, numerical simulations for the generation of a helix design, a 4 and 6 leaf design and a trajectory planning of a picking robot arm are conducted.

Published: February 2020

The hip joint is spheroidal type which allows three movement axes, with a special importance in statics and locomotion. The study of the hip joint by computerized tomography of a male, 52-year-old male patient at the Craiova County Emergency Clinical Hospital was started using Siemens equipment comprised of a magnetic resonance device and a computed tomography apparatus. Were analyzed: hip joint with the two main components of the femur and pelvic bones. To obtain the virtual components of the hip joint, 143 tomographic images from different planes were analyzed. CT images were used to define the normal hip joint. Also, the arthrotic hip virtual model was generated. These two virtual models were subjected to normal walking load and were simulated by the finite element method. The results were analyzed and compared, and important conclusions were finally drawn.
Experimental Determinations on Mechanical Properties for Polyester-Glass Fiber Composite Materials
Authors: Pană Gabriela Monica
Published: February 2020

The mechanical characteristics of a fiber reinforced material depend on a number of parameters related to the structure and characteristics of the component materials, the volumetric distribution, orientation, geometry and adhesion of the fibers to the matrix. The modification of these characteristics over time is due to the varied mechanical demands (repeated or lasting), the thermal and humidity demands, the chemical agents and the influence of aging. The paper presents some observations resulting from experimental tests on polyester-glass composite materials developed in the Materiaux Composites laboratory.
Definition of a land quality index to preserve the best territories from future land take. An application to a study area in Lombardy (Italy)

Published: February 2020

Land take is a process of land-use change in which the agricultural and natural land is taken by residential, industrial, infrastructure and other developments. This change causes the loss of a non-renewable resource, such as the agricultural/natural soil, and the relative natural, cultural and landscape resources. The growing awareness about the loss of ecosystem services related to land take led developed countries to try to reduce the quantity of land taken with new laws and regulations. The European Union has set the goal of zero land take by 2050. It is not only a problem of limiting and slowing down the phenomenon, but it is always clearer that the quality of the land taken has to be assessed and adequately considered during the land-use planning process. In fact, in some cases like in the Lombardy Region, the law focuses not only on reducing the amount of land take, but also on limiting the loss of land with high qualities, requiring municipalities to assess the productive, naturalistic and landscape qualities of the territory. In this paper, the authors develop, using the geographical information system technology, a methodology to define and calculate a composite land quality index (LQI). The methodology has been applied to a case study in the Lombardy region and has allowed to assess the quality of the territory in a rigorous and transparent way using available official data. In order to take into account the relative importance that stakeholders and land-use planners can give to the different components of LQI, analytic hierarchy process has been performed ad 4 different scenarios have been developed. LQI can support the land-use planning process in an ex-ante evaluation of different transformations hypotheses and in the definition of quality-based quantitative thresholds and monitoring of their trend over the time.

In patients undergoing noncardiac surgery risk indices can estimate patients’ perioperative risk of major cardiovascular complications. The indexes currently in use were derived from observational studies that are now outdated with respect to the current clinical context. We undertook a prospective, observational, cohort study to derive, validate, and compare a new risk index with established risk indices. We evaluated 7335 patients (mean age 63±13 years) who underwent noncardiac surgery. Based on prospective data analysis of 4600 patients (derivation cohort) we developed an Updated Cardiac Risk Score (UCRS), and validated the risk score on 2735 patients (validation cohort). Four variables (i.e. the UCRS) were significantly associated with the risk of a major perioperative cardiovascular events: high-risk surgery, preoperative estimate glomerular filtration rate <30 ml/min/1.73 m2, age ≥75 years, and history of heart failure. Based on the UCRS we created risk classes 1,2,3 and 4 and their corresponding 30-day risk of a major cardiovascular complication was 0.8% [95% confidence interval (CI) 0.5-1.7], 2.5 (95% CI 1.6-5.6), 8.7 (95% CI 5.2-18.9) and 27.2 (95% CI 11.8-50.3), respectively. No significant differences were found between the derivation and validation cohorts. Receiver operating characteristic (ROC) curves demonstrate a high predictive performance of the new index, with greater power to discriminate between the various classes of risk than the indexes currently used. The high predictive performance and simplicity of the UCRS make it suitable for wide-scale use in preoperative cardiac risk assessment of patients undergoing noncardiac surgery.
