Violencia y criminalidad: el caso del municipio de Chalco, estado de México.
Authors: Cisneros José Luis
Published: January 2020

Las condiciones actuales de violencia que se viven en México no son privativas de nuestro país, es una situación que se vive en toda la sociedad contemporánea, en algunas con mayor presencia que en otras, de suerte tal que la delincuencia ha constituido en un problema social de particular atención para las ciencias sociales. De ahí la importancia de establecer una reflexión desde la sociología, cruzando el análisis entre la importancia que adquiere el espacio social, en tanto creador de apego e identidad y su relación con el crecimiento de la criminalidad y la violencia como resultado del desapego y arraigo espacial. Particularmente en esta comunicación, apoyados en la revisión de datos oficiales (SESNSP, 2019, INEGI, 2019, INAFEDE, 2018) respeto a las condiciones y reporte de violencia delictiva que se viven en una comunidad, con características de población migrante, como es Chalco, municipio del Estado de México, y apoyados en una metodología cualitativa, exploramos las condiciones y características que se han propiciado el incremento de la violencia delictiva durante el sexenio del Enrique Peña Nieto. Los resultados de la investigación evidencian que las condiciones de vulnerabilidad en las que habitan los pobladores de este municipio han propiciado una cultura de la transgresión, desapego y miedo, impuestos por la violencia delictiva que se vive en la comunidad, y que obligo a sus habitantes, a reconfigurar el uso de sus espacios.

Multiculturalism in Europe: Rise of Islam
Authors: Minardi Anton
Published: January 2020

After 9/11 there was a rise of “islamophobe” with the spreading of negative views on it besides anti-semite and anti-immigrants. Islam in some cases is seen as fundamentalism, radicalism and has a close meaning to terrorism. More than few were found some mistreatment to Muslim community in Europe such as shouting, blaming, exile and another form of discrimination in public sphere. This paper analysis European multiculturalism descriptifly.  Europe is a region which not only recognises cultural and ethnic plurality but also multiculturalism. Its recognition was based on Europe’s identity as a modern and secular society. The population accepted other culture and ethnic rather than only welcomed immigrants. The migrants in Europe especially who came from Asia, Africa and Arab have differentiation in races, languages, habits, religions and their own views. In one hand, the differentiation enriches Europe culture but in the other hand, they have realised that it can be a threat to their identity.  We found a lot of Europeans put their focus in particular on Islam which was spreading and growing as immigrants and new convertions. Nowadays they see the plurality especially to Islam as the integral religion both in private and public sphere as the challenge for their multiculturalism and reviewing to come, to assimilate, and to protect the European majority of Christians identity. Some European leaders agree that minority have to assimilate to the majority.
COLLOCATION METHOD FOR FUZZY VOLTERRA INTEGRAL EQUATIONS OF THE SECOND KIND
Authors: Alijani Zahra , Kangro Urve
Published: January 2020

In this paper we consider fuzzy Volterra integral equation of the second kind whose kernel may change sign. We give conditions for smoothness of the upper and lower functions of the solution. For numerical solution we propose the collocation method with two different basis function sets: triangular and rectangular basis. The smoothness results allow us to obtain the convergence rates of the methods. The proposed methods are illustrated by numerical examples, which confirm the theoretical convergence estimates.
CME-induced Thermodynamic Changes in the Corona as Inferred from Fe xi and Fe xiv Emission Observations during the 2017 August 21 Total Solar Eclipse
Authors: Boe Benjamin , Habbal Shadia , Druckmüller Miloslav , Ding Adalbert , Hodérova Jana , Štarha Pavel
Published: January 2020

We present the first remote sensing observations of the impact from a Coronal Mass Ejection (CME) on the thermodynamic properties of the solar corona between 1 and 3 R
⊙. Measurements of the Fe xi (789.2 nm) and Fe xiv (530.3 nm) emission were acquired with identical narrow-bandpass imagers at three observing sites during the 2017 August 21 Total Solar Eclipse (TSE). Additional continuum imagers were used to observe K+F corona scattering, which is critical for the diagnostics presented here. The total distance between sites along the path of totality was 1400 km, corresponding to a difference of 28 minutes between the times of totality at the first and last site. These observations were used to measure the Fe xi and Fe xiv emission relative to continuum scattering, as well as the relative abundance of Fe10+ and Fe13+ from the line ratio. The electron temperature (T

e
) was then computed via theoretical ionization abundance values. We find that the range of T

e
is (1.1–1.2) × 106 K in coronal holes and (1.2–1.4) × 106 K in streamers. Statistically significant changes of T

e
occurred throughout much of the corona between the sites as a result of serendipitous CME activity prior to the eclipse. These results underscore the unique advantage of multi-site and multi-wavelength TSE observations for probing the dynamic and thermodynamic properties of the corona over an uninterrupted distance range from 1 to 3 R
⊙.
Model-independent Distance Calibration and Curvature Measurement Using Quasars and Cosmic Chronometers
Authors: Wei Jun-Jie , Melia Fulvio
Published: January 2020

We present a new model-independent method to determine spatial curvature and to mitigate the circularity problem affecting the use of quasars as distance indicators. Cosmic-chronometer measurements are used to construct the curvature-dependent luminosity distance

using a polynomial fit. Based on the reconstructed

and the known ultraviolet versus X-ray luminosity correlation of quasars, we simultaneously place limits on the curvature parameter Ω
K
and the parameters characterizing the luminosity correlation function. This model-independent analysis suggests that a mildly closed universe (

) is preferred at the 2.1σ level. With the calibrated luminosity correlation, we build a new data set consisting of 1598 quasar distance moduli, and use these calibrated measurements to test and compare the standard ΛCDM model and the R
h = ct universe. Both models account for the data very well, though the optimized flat ΛCDM model has one more free parameter than R
h = ct, and is penalized more heavily by the Bayes Information Criterion. We find that R
h = ct is slightly favored over ΛCDM with a likelihood of ∼57.7% versus 42.3%.
Neuroprotective and antioxidant activities of saponins’ mixture from Astragalus glycyphylloides in a model of 6-hydroxydopamine-induced oxidative stress on isolated rat brain synaptosomes
Authors: Kondeva-Burdina Magdalena , Krasteva Ilina , Popov Georgi , Manov Vasil
Published: January 2020

The aim of the study was to investigate the possible neuroprotective and antioxidant activity of purified saponins’mixture (PSM), isolated fromAstragalus glycyphylloides(Fabaceae), in a model of 6-hydroxydipamine (6-OHDA)-induced oxidative stress on isolated rat brain synaptosomes. Synaptosomes were incubated with 3 different concentrations of PSM: 60 µg/mL; 6 µg/mL; 0.6 µg/mL. The effects of PSM were compared to those of silymarin (S), at the same concentrations. The main parameters, characterized functional and metabolic status of synaptosomes, were investigated: viability (MTT-test) and level of reduced glutathione (GSH). At isolated rat brain synaptosomes, in conditions of 6-OHDA-induced oxidative stress (150 μМ), PSM revealed statistically significant, concentration-dependent, neuroprotective and antioxidant effects, compared to those of silymarin. Effects were most prominent at concentration 60 µg/mL. These neuroprotective effects of PSM might be due to the possible activity as scavenger of reactive oxygen species (ROS), produced by p-quinone (toxic metabolite of 6-OHDA).
« Cette semaine, je garde papa ». Dans les séparations dites sereines : quelle charge imaginaire et réelle pour l’enfant ?
Authors: Sand Léa
Published: January 2020

À partir de son écoute de psychanalyste avec des enfants et des adultes, l’auteure s’interroge quant aux aménagements nouveaux de la répartition du temps et des espaces entre les parents séparés et désireux de préserver le lien avec leurs enfants. D’une part, les discours banalisent la séparation en s’appuyant sur une réalité statistique qui témoigne de la fréquence des divorces, d’autre part ils tentent d’atténuer les effets mortifères sur les enfants en déniant la réalité du changement, quel que soit l’aménagement spatio-temporel de la nouvelle configuration familiale. L’enfant est souvent appelé à faire allégeance au fantasme de la continuité, en dépit de la rupture ; à charge pour lui d’assumer la mort d’un projet familial, dans le travail de deuil de la famille.
Approche clinique en dispositif de placement externalisé. Promouvoir la séparation psychique sans séparation physique : une gageure ?
Authors: Picoche Gaëlle , Bonneville-Baruchel Emmanuelle
Published: January 2020

Le présent article concerne un dispositif particulier de placement pour les mineurs pris en charge par les services départementaux de l’Aide sociale à l’enfance, le dispositif de placement dit « externalisé ». Fondé sur des expériences cliniques de terrain auprès des familles et des intervenants élaborées dans le cadre d’une recherche universitaire, cet article propose un modèle de ce dispositif dans lequel une approche et une intervention cliniques peuvent s’articuler aux approches et interventions éducatives et sociales. Il vise aussi à présenter certaines conditions et certaines des limites du dispositif. Il met l’accent sur la nécessité de l’évaluation initiale, continue et pluridisciplinaire, incluant l’approche clinique, afin de travailler l’indication de ce dispositif qui ne peut convenir à toutes les problématiques familiales.
Séparation impossible, sinon radicale
Authors: Mansouri Malika
Published: January 2020

Lesdits « radicalisés » ne sont pas exceptionnels. Ce sont principalement des adolescents dont la complexité des trajectoires individuelles et familiales peut entraver la nécessaire séparation d’avec l’enfance pour se construire un devenir adulte. La clinique nous fait découvrir la multiplicité des stratégies possibles de l’adolescent prisonnier de ce dilemme. L’article analyse le cas d’une jeune fille aux prises d’un héritage familial traumatique et de sa propre régression archaïque, qui tente une séparation physique avec le vœu inconscient de parvenir à se séparer enfin psychiquement. Mais les séparations physiques, même radicales, ne favorisent, au contraire, que séparation sans séparation.
L’Équateur, un nouvel imaginaire politique. Le développement comme processus politique
Authors: Correa Rafael
Published: January 2020

Ce texte propose une analyse de la politique de développement économique mise en œuvre par l’Équateur entre 2007 et 2016. Dressant un bilan détaillé des évolutions économiques et sociales de la période, Rafael Correa, ancien Président de l’Équateur et professeur d’économie, réalise ce bilan en acteur engagé et militant. En expliquant les résultats obtenus sur le plan de la lutte contre la pauvreté ou des investissements pour l’avenir (infrastructures et éducation, notamment), il en profite pour déduire quelques leçons pour la conduite du développement au Sud. L’importance du choix politique, de l’appui sur les volontés majoritaires des citoyens mais aussi des nécessaires luttes pour sortir de l’application des idées « injustes » liées au consensus de Washington est discutée.

Management of Acute Conjunctivitis in School-Aged Children
Authors: Wagner Rudolph S.
Published: January 2020

EXCERPT

Pediatric ophthalmologists participating in presentations or informal discussions with pediatricians and school nurses on the topic of conjunctivitis in children are frequently asked when children diagnosed as having acute conjunctivitis can return to school. Their response to this question impacts the health of these children and their classmates, and may require their parents to juggle their work schedules and childcare arrangements. The Red Book (Pickering LK, Baker CJ, Long SS, McMillan JA, eds. Red Book: 2006 Report of the Committee on Infectious Diseases, 27th ed. Elk Grove Village, IL: American Academy of Pediatrics; 2006) provides a general guideline, recommending that, “Except when viral or bacterial conjunctivitis is accompanied by systemic signs of illness, infected children should be allowed to remain in school once any indicated therapy is implemented, unless their behavior is such that close contact with other students cannot be avoided.” The latter part of this statement is certainly open to interpretation.

Published: January 2020

BACKGROUND AND OBJECTIVE:

To describe the microvascular features of treated, clinically regressed, or reactivated retinoblastoma lesions using an investigational portable optical coherence tomography angiography (OCTA) system.

PATIENTS AND METHODS:

Single-center, prospective, cross-sectional, consecutive case-series of children with previously treated retinoblastoma who underwent portable OCTA of posterior retinoblastoma lesions.

RESULTS:

Eight tumors from seven eyes of five children with retinoblastoma were included. Tumors with types 1 (calcified remnant, n = 3), 2 (non-calcified remnant, n = 1), and 3 (both calcified and noncalcified remnants, n = 1) regression revealed persistent intrinsic superficial vasculature on OCTA (five of five lesions; 100%). Lesions with type 4 regression (atrophic scar, n = 2) had complete vascular flow voids in the involved retina and underlying choriocapillaris. A reactivated tumor (n = 1) showed a distinct area of vascularity with prominent feeder/draining vessels.

CONCLUSIONS:

OCTA revealed that significant vascularity exists in inactive retinoblastoma lesions. Dilated feeder vessels may suggest continued disease activity.

Utilization of unsaponifiable matter from rice bran oil fatty acid distillate for preparing an antioxidant-rich oleogel and evaluation of its properties
Authors: Sahu S. , Ghosh M. , Bhattacharyya D. K.
Published: January 2020

Rice bran oil fatty acid distillate (RBOFAD) is an important by-product obtained from the physical refining process. This fatty acid distillate contains high a amount of Unsaponifiable Matter (γ-oryzanol 3.27 gm/100gm UM; total tocopherol 10.93 mg/100 g UM; total phytosterol 21.81 g/100g UM; squalene 1.15 g/100 g UM and total fatty alcohol 73.34 g/100 g UM) and free fatty acids. Antioxidant-rich Oleogels were obtained from rice bran wax (RBW), rice bran oil fatty acid distillate (RBOFAD) and refined rice bran oil. The main objective of this study was to utilize the antioxidant-rich unsaponifiable matter of RBOFAD (UMRBOFAD) as an organogelator along with rice bran wax, which also acts as a good organogelator. Antioxidant-rich oleogel was prepared using UMRBFAD, ethylcellulose (EC) and RBW at 2%, 2%, 3% on weight basis, respectively, in refined rice bran oil and this antioxidant-rich oleogel was compared with rice bran oil oleogel using RBW at 7% on weight basis of rice bran oil. These oleogels were evaluated using a combination of techniques such as differential scanning calorimetry (DSC), polarized light microscopy (PLM), Viscosity, synchrotron radiation X-ray diffraction (SR-XRD) and FTIR Spectroscopy. The differential scanning calorimetry (DSC) measured the thermal properties of rice bran oil oleogel and high antioxidant-rich oleogel. Polarized light microscopy images revealed needle-like crystals for RBW. SR-XRD measurements were used for clarification of the crystal structures of the building blocks of these oleogels. The antioxidant activities of oleogels were evaluated involving DPPH and ABTS assays.
Effect of process variables on the yield and quality of jerivá (Syagrus romanzoffiana) kernel oil from aqueous extraction
Authors: Magalhães K. T. , Tavares T. S. , Gomes T. M.C. , Nunes C. A.
Published: January 2020

The fruit from jerivá (Syagrus romanzoffiana) has a kernel which is rich in oil, and has a pleasant smell that reminds one of coconut. It is rich in monounsaturated and saturated fatty acids, in addition to bioactive compounds. In this work, the effect of process variables on the yield and quality of jerivá kernel oil from aqueous extraction was evaluated using response surface methodology. The variables pH, time and temperature influenced the yield and the quality of the oil. High pH and time, along with mild temperature were suitable conditions to extract jerivá kernel oil by aqueous extraction, but excessively high pH, temperature and time negatively impacted the oil’s quality. pH was the only variable that significantly influenced free acidity, with a decrease in free acidity with the increase in pH. On the other hand, the increase in pH, time and temperature increased the peroxide value, which limited some conditions for obtaining jerivá kernel oil by aqueous extraction. The optimal conditions were found to be an extraction at pH 12, 25 °C and 60 minutes, which resulted in a yield of 39%, free acidity of 0.2% and a peroxide value of 5.8 meqO2·kg-1. Aqueous extraction yielded more unsaturated oil than that extracted with hexane, in addition to a higher proportion of caproic, oleic and linoleic acids, thus improving its nutritional characteristics and health benefits, despite decreasing its oxidative stability.

Edificaciones reveladoras. Monumentos y « lugares de memoria » : configuraciones urbanas de conflictos latinoamericanos del siglo XXI
Authors: Solomianski Alejandro
Published: January 2020

Al tornarse hechos de « sentido común » el fin de la « Guerra Fría » y su promulgada caída de las mega-narrativas, los estudios culturales se abrieron al análisis de objetos y espacios extra-discursivos y ampliaron su densidad investigativa al momento de enfocar las disposiciones espaciales urbanas. El entramado citadino pasó a entenderse como un texto en el que podría leerse no solamente la condensación de las subjetividades ciudadanas locales y nacionales, sino también las identidades configuradas a escala global. El presente estudio se centra en los avatares político-ideológicos y las conformaciones estéticas que pueden cuestionarse a partir del reciclado del « Penal de Punta Carretas » como « Punta Carretas Shopping Mall » (Montevideo, 1994) ; el reemplazo del monumento a Cristóbal Colón por el de la heroína libertadora Juana Azurduy (Buenos Aires, 2015) y la articulación de la « Plaza de la Transparencia » (San Salvador, 2017).
Chateaubriand en Amérique : christianiser les grands espaces ?
Authors: Baudoin Sébastien
Published: January 2020

Chateaubriand considère l’Amérique comme une terre de liberté : au sein de la wilderness, il s’envisage comme un être en devenir et trouve, entre christianisme et paganisme, sa véritable vocation d’écrivain des grands espaces. Après avoir considéré la perception chrétienne de ce « Nouvel Eden » puis la tentation persistante d’une nature sensuelle et désirée, nous envisagerons la sublimation de cette tension par le vertige de l’expérience et la révélation de la destinée d’écrivain qui résout l’énigme de l’être.
Le Testament d’un excentrique de Jules Verne (1899) : un jeu de l’oie grandeur nature ou les États-Unis mode d’emploi
Authors: Lévêque Laure
Published: January 2020

Cet article s’attache à suivre, dans un roman trop méconnu de Jules Verne, Le Testament d’un excentrique (1899), l’art subtil selon lequel l’auteur déjoue les codes narratifs apparemment revendiqués et, sous couvert de roman ludique, oulipien avant la lettre, s’emploie à conduire une lecture seconde qui a tout d’une contre lecture, laquelle s’intéresse moins aux personnages qu’elle ne concerne les États-Unis, qui retiennent ici autant comme décor que pour ce qui affleure d’envers du décor. Parcourus par le roman, les espaces états-uniens, malmenés par le protocole d’écriture qui joue à plein des coq-à-l’âne, sont à la fois reliés et relus selon des modalités qui cassent les logiques reçues, livrant, cum grano salis, une réinterprétation tout ensemble amusée et démystifiante des mythes fondateurs de la culture américaine.

The microstructural evolution and deformation mechanisms are still challenging issues, and it is hard to observe directly by experimental methods. Accordingly, in this paper atomic simulations are performed to investigate the uniaxial compressive behavior of Al/Mg phases; with different ratio of Mg ranging from 31% to 56%. The compression is at the same strain rate (3.1010s⁻¹), at the same temperature (300K) and pressure, using embedded atom method (EAM) potential to model the interactions and the deformation behavior between Al and Mg.From these simulations, we get the radial distribution function; the stress–strain responses to describe the elastic and plastic behaviors of β-Al3Mg2, ε-Al30Mg23, Al1Mg1and γ-Al12Mg17phases with 31, 41, 50 and 56% of Mg added to pure aluminum, respectively. The mechanical properties, such as Young’s modulus, elasticity limit and rupture pressure, are determined and presented. The engineering equation was used to plot the stress-strain curve for each phase.From the results obtained, the chemical composition has a significant effect on the properties of these phases. The stress-strain behavior comprised elastic, yield, strain softening and strain hardening regions that were qualitatively in agreement with previous simulations and experimental results. These stress-strain diagrams obtained show a rapid increase in stress up to a maximum followed by a gradual drop when the specimen fails by ductile fracture. Under compression, the deformation behavior of β-Al3Mg2and γ-Al12Mg17phases is slightly similar. From the results, it was found that ε-Al30Mg23phase are brittle under uniaxial compressive loading and γ-Al12Mg17phase is very ductile under the same compressive loading.The engineering stress-strain relationship suggests that β-Al3Mg2and γ-Al12Mg17phases have high elasticity limit, ability to resist deformation and also have the advantage of being highly malleable. From this simulation, we also find that the mechanical properties under compressive load of ε-Al30Mg23phase are evidently less than other phases, which makes it the weakest phase. The obtained results were compared with the previous experimental studies, and generally, there is a good correlation.The Al-Mg system was built and simulated using molecular dynamics (MD) software LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator).

The acceptance and application of functional parts produced via additive manufacturing technologies is faced with challenges of poor surface finish, dimensional accuracy and mechanical properties among other which is mostly dependent on process parameters employed. In this study, the effect of infill density, layer thickness and extrusion temperature on mechanical properties of polylactic acid (PLA) part manufactured using fused deposition modelling process was investigated to obtain optimum process parameters to achieve the best properties. Solid cuboid bars were produced from which tensile, impact and hardness test specimens were obtained. A statistical approach based on Taguchi design of experiment was employed with process parameters varied and grey relational analysis coupled with principal component analysis was employed to obtain the unified optimum parameter. The single optimisation results showed that 50% infill density, 220°C extrusion temperature and 0.4 mm layer thickness resulted in best tensile strength; 30% density, 210°C temperature and 0.2 mm layer thickness is required to achieve the best impact strength, while 50% density, 215°C temperature and 0.3 mm thickness is required for highest hardness. The multi-response optimisation indicated that for the best of all the three properties to be achieved at once in a PLA built part, 50% infill density, 220°C extrusion temperature and 0.3 mm is required which yielded tensile strength of 30.02±2.15 MPa, impact strength 4.20±0.12 J and hardness of 76.80±0.38 BHN.

In this paper a numerical modeling was carried out to study the problem of plane elasticity in a medium cracked by the method of the extended finite elements (XFEM) in a thin cracked plate made of aluminum using the software Abaqus 6.13.This method improved the capability of the classical finite element method especially the crack propagation problems. Furthermore, the extended finite elements method has been used to simulate tensile and fracture behavior of the study materials. Based on variation in size and shape of crack, the results obtained will be compared with those obtained experimentally, this comparison shows a good agreement.

The rising awareness of the importance of moringa seeds has geared interest in its mass production. A major step in making the seed available for it vast usage is shelling. Most rural farmers of moringa seed use the traditional methods of shelling. These methods are tedious, time consuming with attendance low outputs that produce unhygienic products. The need to develop appropriate machines and equipment for processing of moringa seeds become necessary. This work developed a moringa seed shelling machine using available local materials. The development of the shelling machine was based on engineering mechanics of impact and shearing forces. The machine consists of a hopper, shelling unit, shafts, cleaning unit, sieve, discharge unit, power transmission unit and frame. The machine was evaluated based on variation in speed and feedrate to obtain the shelling efficiency, throughput capacity and percentage seed damage at 14% (d.b) moisture content powered by a 0.75 kW electric motor. The results obtained show that the machine has the highest shelling efficiency of 72.72% at 60 g/min feedrate with a throughput capacity of 8.31 kg/hr and the minimum percentage seed breakage of 2.22%. Machine speed of 250 rpm favoured the smooth operation and performance of the machine. The machine is very useful for rural people, farmers and small scale industries for post-harvest processing of moringa seeds since it cost and operational principle is within their technical know-how and capability.
A Review of Development of Zirconium Alloys as a Fuel Cladding Material and its Oxidation Behavior at High-Temperature Steam

Published: January 2020

Currently, Zr-alloys are widely used in nuclear power reactors for fuel cladding and structural components. Many types of zr-based alloys were developed to overcome the challenges encountered in the progress of nuclear reactors (high-burnup and high-duty). Oxygen diffused into the cladding, hydrogen absorbed in the cladding (breakaway oxidation and ruptured balloons) and rapid oxidation rate are results of chemical interaction of cladding material with steam at high temperature. Zirconium alloys seem to be the most suitable for use in fuel cladding, if they can overcome the rapid oxidation at temperature higher than 1200 °C. Previous studies on the oxidation behavior for some Zr-alloys nuclear fuel cladding tubes in steam and steam–air atmospheres at high temperatures are reviewed. The oxidation behavior of zirconium-alloys is strongly affected by the chemical composition of alloys and its surface conditions.

Published: January 2020

This paper presents a facial expressions recognition system to command both mobile and arm robot. The proposed system mainly consists of two modules: facial expressions recognition and robots command. The first module aims to extract the ROI (Region Of Interest like: mouth, eyes, eyebrow) using Gradient Vector Flow (GVF) snake segmentation and the Euclidian distance calculation (compatible with the MPEG-4 description of the six universal emotions). To preserve the temporal aspect of the processing from FEEDTUM database (video file), Time Delay Neural Network (TDNN) is used as classifier of the universal facial expressions such as happiness, sadness, surprise, anger, fear, disgust and neutral. While the second module, analyzes recognized facial expressions and translates them into a language to communicate with robots by establishing command law.

Published: January 2020

This paper employs a comparative study between three recent versions of particle swarm optimization (PSO) algorithm to find the optimal scheduling of reactive power resources. Scheduling of reactive power resources is formulated as non-linear complex optimal reactive power dispatch (ORPD) problem. The main objective function of ORPD is to minimize the transmission power losses (Ploss). For this target, three modified versions, which present three variations applied on velocity equation of PSO algorithm, are considered. To achieve fair comparative study, the competitive versions are checked through 13 studied cases on IEEE 14-, 30-, 57- and 118-bus test systems. The effectiveness of these variations is proven for the non-linear complex optimization ORPD problem with different decision variables according to the system size. The obtained results confirm that these variations on PSO algorithm can make a noticeable reduction of Ploss at acceptable level in terms of power system operation view point.

Objectives: To determine the prevalence of sexual dysfunction in male partners of infertile couples and evaluate the effect of childlessness on erectile dysfunction (ED) and sexual relationship stress. Materials and methods: We collected datas of couples who attended our clinics for infertility between 2009 and 2016. Erectile dysfunction was investigated with the Questionnaires of International Index of Erectile Function-15 (IIEF-15) whereas premature ejaculation (PE) status with the Premature Ejaculation Diagnostic Tool (PEDT). The stress status of the childlessness in terms of sexual intercourse was scored by the Visual analogue scale (VAS) questionnaire. These scores were measured before and after a successful assisted reproductive treatment with the birth of the child. Results: The median age of the 193 male patients was 31 years (range 23-48). Erectile dysfunction was found in 68 (35.2%) and PE in 42 (21.7%) subjects. One hundred and forty-one couples were treated with assisted reproductive treatments. Forty eight couples had successful pregnancy. The IIEF-15 test was repeated after the birth of the child to the male partners of these couples. We observed that the IIEF-15 scores increased from 16 to 21 (p = 0.014). However there were no significant improvement on their ejaculation status (p > 0.05). The mean VAS scores of male partners was 5.2 (3-10) in the treatment period while it decreased to 4.1 (0-8) after the birth of the chils (p = 0.02). Statistically analysis showed a correlation between VAS and infertility as did IIEF-15. Conclusions: We observed that having children has a reducing effect on sexual relationship stress. Infertility is absolutely blamed on the women and men. This condition may have negative effects on male sexual performance and it is closely related with some emerging female sexual disorders. It should be taken into consideration that infertile couples may have sexual dysfunction.

Published: January 2020

Context

Several studies have been conducted to better understand the effect of load on the Achilles tendon structure. However, the effect of a high cumulative load consisting of repetitive cyclic movements, such as those that occur during the running of a marathon, on Achilles tendon structure is not yet clear. Clinicians, coaches, and athletes will benefit from knowledge about the effects of a marathon on the structure of the Achilles tendon.

Objective

To investigate the short-term response of the Achilles tendon structure to running a marathon.

Design

Case series (prospective).

Setting

Sports medicine centers.

Patients or Other Participants

Ten male nonelite runners who ran in a marathon.

Main Outcomes Measure(s)

Tendon structure was assessed before and 2 and 7 days after a marathon using ultrasound tissue characterization (UTC), an imaging tool that quantifies tendon organization in 4 echo types (I–IV). Echo type I represents the most stable echo pattern, and echo type IV, the least stable.

Results

At 7 days postmarathon, both the insertional and midportion structure changed significantly. At both sites, the percentage of echo type II increased (insertion P < .01; midportion P = .02) and the percentages of echo types III and IV decreased (type III: insertion P = .01; midportion P = .02; type IV: insertion P = .01; midportion P < .01). Additionally, at the insertion, the percentage of echo type I decreased (P < .01).

Conclusions

We observed the effects of running a marathon on the Achilles tendon structure 7 days after the event. Running the marathon combined with the activity performed shortly thereafter might have caused the changes in tendon structure. This result emphasizes the importance of sufficient recovery time after running a marathon to prevent overuse injuries.
