Determination of Adulteration Content in Extra Virgin Olive Oil Using FT-NIR Spectroscopy Combined with the BOSS–PLS Algorithm
Authors: Jiang Hui , Chen Quansheng
Published: June 2019

This work applied the FT-NIR spectroscopy technique with the aid of chemometrics algorithms to determine the adulteration content of extra virgin olive oil (EVOO). Informative spectral wavenumbers were obtained by the use of a novel variable selection algorithm of bootstrapping soft shrinkage (BOSS) during partial least-squares (PLS) modeling. Then, a PLS model was finally constructed using the best variable subset obtained by the BOSS algorithm to quantitative determine doping concentrations in EVOO. The results showed that the optimal variable subset including 15 wavenumbers was selected by the BOSS algorithm in the full-spectrum region according to the first local lowest value of the root-mean-square error of cross validation (RMSECV), which was 1.4487 % v/v. Compared with the optimal models of full-spectrum PLS, competitive adaptive reweighted sampling PLS (CARS–PLS), Monte Carlo uninformative variable elimination PLS (MCUVE–PLS), and iteratively retaining informative variables PLS (IRIV–PLS), the BOSS–PLS model achieved better results, with the coefficient of determination (R2) of prediction being 0.9922, and the root-mean-square error of prediction (RMSEP) being 1.4889 % v/v in the prediction process. The results obtained indicated that the FT-NIR spectroscopy technique has the potential to perform a rapid quantitative analysis of the adulteration content of EVOO, and the BOSS algorithm showed its superiority in informative wavenumbers selection.

Authors: Lutz Mariane , Petzold Guillermo , Albala Cecilia
Published: June 2019

The population of older adults is growing globally. This increase has led to an accumulation of chronic illnesses, so-called age-related diseases. Diet and nutrition are considered the main drivers of the global burden of diseases, and this situation applies especially to this population segment. It relates directly to the development of coronary heart disease, hypertension, some types of cancer, and type 2 diabetes, among other diseases, while age-associated changes in body composition (bone and muscle mass, fat, sarcopenia) constitute risk factors for functional limitations affecting health status and the quality of life. Older adults present eating and swallowing problems, dry mouth, taste loss, and anorexia among other problems causing “anorexia of aging” that affects their nutritional status. The strategies to overcome these situations are described in this study. The impact of oral food processing on nutrition is discussed, as well as approaches to improve food acceptance through the design of innovative foods. These foods should supply a growing demand as this group represents an increasing segment of the consumer market globally, whose needs must be fulfilled.

Published: June 2019

Dietary advice constitutes one of the first choices of treatment for irritable bowel syndrome (IBS). We have recognized an increased prevalence of sucrase-isomaltase (SI) gene variants in IBS patients, possibly rendering starch- and sucrose-intolerance. The aims were to examine participants’ dietary habits at baseline, to correlate habits with gastrointestinal (GI) symptoms and blood levels of minerals and vitamins, and to examine the effect of a starch- and sucrose-reduced diet (SSRD) on GI symptoms. In the study 105 IBS patients (82 women, 46.06 ± 13.11 years), irritable bowel syndrome-symptom severity scale (IBS-SSS)>175, were randomized to SSRD for 2 weeks or continued ordinary eating habits. Blood samples, visual analog scale for irritable bowel syndrome (VAS-IBS), IBS-SSS, and 4-day food diaries were collected at baseline and after 2 weeks. Patients with irregular dietary habits exhibited higher IBS-SSS than patients with regular habits (p = 0.029). Women already on a diet had lower ferritin levels than others (p = 0.029). The intervention led to 66.3% of patients being responders, with differences in the change of IBS-SSS (p < 0.001), abdominal pain (p = 0.001), diarrhea (p = 0.002), bloating and flatulence (p = 0.005), psychological well-being (p = 0.048), and intestinal symptoms’ influence on daily life (p < 0.001), compared to controls. Decreased intake of cereals and sweets/soft drinks correlated with decreased scores.
Development and In Vitro-In Vivo Evaluation of a Novel Sustained-Release Loxoprofen Pellet with Double Coating Layer
Authors: Wan Dongwei , Zhao Min , Zhang Jingjing , Luan Libiao
Published: June 2019

This study aimed to develop a novel sustained release pellet of loxoprofen sodium (LXP) by coating a dissolution-rate controlling sub-layer containing hydroxypropyl methyl cellulose (HPMC) and citric acid, and a second diffusion-rate controlling layer containing aqueous dispersion of ethyl cellulose (ADEC) on the surface of a LXP conventional pellet, and to compare its performance in vivo with an immediate release tablet (Loxinon®). A three-level, three-factor Box-Behnken design and the response surface model (RSM) were used to investigate and optimize the effects of the citric acid content in the sub-layer, the sub-layer coating level, and the outer ADEC coating level on the in vitro release profiles of LXP sustained release pellets. The pharmacokinetic studies of the optimal sustained release pellets were performed in fasted beagle dogs using an immediate release tablet as a reference. The results illustrated that both the citric acid (CA) and ADEC as the dissolution- and diffusion-rate controlling materials significantly decreased the drug release rate. The optimal formulation showed a pH-independent drug release in media at pH above 4.5 and a slightly slow release in acid medium. The pharmacokinetic studies revealed that a more stable and prolonged plasma drug concentration profile of the optimal pellets was achieved, with a relative bioavaibility of 87.16% compared with the conventional tablets. This article provided a novel concept of two-step control of the release rate of LXP, which showed a sustained release both in vitro and in vivo.
Analogy and Communication
Authors: Dussel Enrique
Published: June 2019

Analogy makes possible the dialogue between people. This dialogue, at the intercultural level and from distinct ontological comprehensions of life, cannot be achieved from a univocal pretension of meaning. Analogy permits, especially at the rhetoric level of Political Philosophy, an adequate interpretation of such complex concepts as people, state or rights. A semantics of these concepts by similarity allows us to advance in the process towards a better interpretation of the other interlocutor’s expression though never reaching identity.
Statistical Assessment of Open Optical Networks

Published: June 2019

In order to cope with the increase of the final user traffic, operators and vendors are pushing towards physical layer aware networking as a way to maximize the network capacity. To this aim, optical networks are becoming more and more open by exposing physical parameters enabling fast and reliable estimation of the lightpath quality of transmission. This comes in handy not only from the point of view of the planning and managing of the optical paths but also on a more general picture of the whole optical network performance. In this work, the Statistical Network Assessment Process (SNAP) is presented. SNAP is an algorithm allowing for estimating different network metrics such as blocking probability or link saturation, by generating traffic requests on a graph abstraction of the physical layer. Being aware of the physical layer parameters and transceiver technologies enables assessing their impact on high level network figures of merit. Together with a detailed description of the algorithm, we present a comprehensive review of several results on the networking impact of multirate transceivers, flex-grid spectral allocation as a means to finely exploit lightpath capacity and of different Space Division Multiplexing (SDM) solutions.
Oxidation of P700 Induces Alternative Electron Flow in Photosystem I in Wheat Leaves

Published: June 2019

Oxygen (O2)-evolving photosynthetic organisms oxidize the reaction center chlorophyll, P700, in photosystem I (PSI) to suppress the production of reactive oxygen species. The oxidation of P700 is accompanied by alternative electron flow in PSI (AEF-I), which is not required for photosynthetic linear electron flow (LEF). To characterize AEF-I, we compared the redox reactions of P700 and ferredoxin (Fd) during the induction of carbon dioxide (CO2) assimilation in wheat leaves, using dark-interval relaxation kinetics analysis. Switching on an actinic light (1000 μmol photons m−2 s−1) at ambient CO2 partial pressure of 40 Pa and ambient O2 partial pressure of 21 kPa gradually oxidized P700 (P700+) and enhanced the reduction rate of P700+ (vP700) and oxidation rate of reduced Fd (vFd). The vFd showed a positive linear relationship with an apparent photosynthetic quantum yield of PSII (Y[II]) originating at point zero; the redox turnover of Fd is regulated by LEF via CO2 assimilation and photorespiration. The vP700 also showed a positive linear relationship with Y(II), but the intercept was positive, not zero. That is, the electron flux in PSI included the electron flux in AEF-I in addition to that in LEF. This indicates that the oxidation of P700 induces AEF-I. We propose a possible mechanism underlying AEF-I and its physiological role in the mitigation of oxidative damage.

Published: June 2019

Biomaterials should be bioactive in stimulating the surrounding tissue to accelerate the ingrowth of permanent implants. Chemical and topographical features of the biomaterial surface affect cell physiology at the interface. A frequently asked question is whether the chemistry or the topography dominates the cell-material interaction. Recently, we demonstrated that a plasma-chemical modification using allylamine as a precursor was able to boost not only cell attachment and cell migration, but also intracellular signaling in vital cells. This microwave plasma process generated a homogenous nanolayer with randomly distributed, positively charged amino groups. In contrast, the surface of the human osteoblast is negatively charged at −15 mV due to its hyaluronan coat. As a consequence, we assumed that positive charges at the material surface—provoking electrostatic interaction forces—are attractive for the first cell encounter. This plasma-chemical nanocoating can be used for several biomaterials in orthopedic and dental implantology like titanium, titanium alloys, calcium phosphate scaffolds, and polylactide fiber meshes produced by electrospinning. In this regard, we wanted to ascertain whether plasma polymerized allylamine (PPAAm) is also suitable for increasing the attractiveness of a ceramic surface for dental implants using Yttria-stabilized tetragonal zirconia.
A Survey on Congestion Control for RPL-Based Wireless Sensor Networks
Authors: Lim Chansook
Published: June 2019

RPL (IPv6 routing protocol for low power and lossy networks) proposed by the IETF (Internet Engineering Task Force) ROLL (routing over low-power and lossy networks) working group is a de facto standard routing protocol for IoT environments. Since the standardization was proposed, RPL has been extensively improved for diverse application scenarios and environments. Congestion control is one of the most important reasons why RPL has been improved. In an LLN (low power and lossy network), congestion may even lead to network lifetime reduction. In resource-constrained networks where end-to-end congestion control is not feasible, RPL should play a more crucial role in congestion control. In this survey, we review the RPL schemes proposed for congestion control and load-balancing and discuss future research directions.

Published: June 2019

A device to train children in time orientation has been designed, developed and evaluated. It is framed within a long-term cooperation action between university and special education school. It uses a specific cognitive accessible time display: Time left in the day is represented by a row of luminous elements initially on. Time passing is represented by turning off sequentially and gradually each luminous element every 15 min. Agenda is displayed relating time to tasks with standard pictograms for further accessibility. Notifications of tasks-to-come both for management support and anticipation to changes uses visual and auditory information. Agenda can be described in an Alternative and Augmentative Communication pictogram language already used by children, supporting individual and class activities on agenda. Validation has been performed with 16 children in 12 classrooms of four special education schools. Methodology for evaluation compares both prior and posterior assessments which are based in the International Classification of Functioning, Disability and Health (ICF) from the World Health Organization (WHO), together with observation registers. Results show consistent improvement in performances related with time orientation.
Queerly Unequal: LGBT+ Students and Mentoring in Higher Education
Authors: Graham Brooke Erin
Published: June 2019

Sociological research has illuminated the importance of mentoring relationships, especially in regard to education. The literature has also shown that mentoring can help disadvantaged students access social and cultural capital that aids their academic achievement. Furthermore, mentoring relationships are more successful between mentees and mentors of the same race, class, or gender. However, there is little research about queer students’ experiences with mentoring relationships in regard to education. In an effort to expand the literature on mentoring relationships and queer students I conducted ten in-depth interviews with queer identified undergraduate students at a large university in the Southeast United States. Using these interviews, I examined respondents’ perception of their social exclusion, coping through resiliency, and prosocial behavior through mentoring others. I found that being openly queer posed an identity-based risk for students’ ability to access mentoring relationships, in turn this risk increased their perception of resiliency and prosocial behavior.
Direct and Indirect Effects of Urbanization on Energy Intensity in Chinese Cities: A Regional Heterogeneity Analysis
Authors: Lv Yulan , Chen Wei , Cheng Jianquan
Published: June 2019

Energy intensity reduction has become a constrained target from the 11th five-year plan in China. Energy consumption is expected to increase because of rapid urbanization and economic growth, whereas energy intensity reduction is regarded as a method to alleviate the pressure of growing energy demand. An important contribution of this study is the investigation of urbanization impact on energy intensity across China at the urban level. This research uses a balanced panel data set of 224 cities for the period between 2005 and 2016 and reports deep insights into and innovative findings for the reduction of energy intensity across different regions and cities in China. To examine the direct, indirect, and total effects and regional heterogeneous effects, we employ spatial Durbin models and spatial decomposition techniques. It reveals significant and negative direct effects of urbanization in the western and full regions. However, the indirect and total effects of urbanization are significantly negative in the eastern and western regions. The pressure of urbanization on energy has alleviated and is reversing, especially under the construction of people-oriented and green new-type urbanization. The empirics highlight industrialization as a contributing factor for high energy intensity in the spatial outcomes of regional analysis. The direct effect of per capita GDP supports the existence of the inverted U-shaped relationship between economic development and energy intensity. The study proposes fruitful implications to construct new-type urbanization for energy conservation and sustainable development in China.
Performance of an On-Site Wastewater Treatment System Using Reactive Filter Media and a Sequencing Batch Constructed Wetland
Authors: Hamisi Rajabu , Renman Agnieszka , Renman Gunno
Published: June 2019

Many on-site wastewater treatment systems, such as soil treatment systems, are not sustainable in terms of purification efficiency, nutrient recycling potential, and economics. In this case study, a sequencing batch constructed wetland (SBCW) was designed and added after a package treatment plant (PTP) using reactive filter media for phosphorus (P) removal and recycling. The treatment performance of the entire system in the start-up phase and its possible applicability in rural areas were investigated. Raw and treated effluents were sampled during a period of 25 weeks and analyzed for nitrogen, phosphorus, BOD7, and bacteria. Field measurements were made of wastewater flow, electrical conductivity, oxygen, and temperature. The entire system removed total-P and total inorganic nitrogen (TIN) by 83% and 22%, respectively. High salt concentration and very low wastewater temperature were possible reasons for these unexpectedly low P and TIN removal efficiencies. In contrast, removal rates of bacteria (Escherichia coli, enterococci) and organic matter (as BOD) were high, due to filtration in the alkaline medium Polonite® (Ecofiltration Nordic AB, Stockholm, Sweden) and the fine sand used as SBCW substrate. High pH in effluent from the PTP was efficiently reduced to below pH 9 in the SBCW, meeting recommendations by environmental authorities in Sweden. We concluded that treating cold on-site wastewater can impair treatment performance and that technical measures are needed to improve SBCW performance.

Published: June 2019

Internet of things is developing at a dizzying rate, and companies are forced to implement it in order to maintain their operational efficiency. The high flexibility inherent to these technologies makes it necessary to apply an appropriate measure, which properly assesses risks and rewards. Real options methodology is available as a tool which fits the conditions, both economic and strategic, under which investment in internet of things technologies is developed. The contribution of this paper is twofold. On the one hand, it offers an adequate tool to assess the strategic value of investment in internet of things technologies. On the other hand, it tries to raise awareness among managers of internet of things technologies because of their potential to contribute to economic and social progress. The results of the research described in this paper highlight the importance of taking action as quickly as possible if companies want to obtain the best possible performance. In order to enhance the understanding of internet of things technologies investment, this paper provides a methodology to assess the implementation of internet of things technologies by using the real options approach; in particular, the option to expand has been proposed for use in the decision-making process.

Authors: Jiang Haiyang , Pan Yaozong , Zhang Jian , Yang Haitao
Published: June 2019

In this paper, our goal is to improve the recognition accuracy of battlefield target aggregation behavior while maintaining the low computational cost of spatio-temporal depth neural networks. To this end, we propose a novel 3D-CNN (3D Convolutional Neural Networks) model, which extends the idea of multi-scale feature fusion to the spatio-temporal domain, and enhances the feature extraction ability of the network by combining feature maps of different convolutional layers. In order to reduce the computational complexity of the network, we further improved the multi-fiber network, and finally established an architecture—3D convolution Two-Stream model based on multi-scale feature fusion. Extensive experimental results on the simulation data show that our network significantly boosts the efficiency of existing convolutional neural networks in the aggregation behavior recognition, achieving the most advanced performance on the dataset constructed in this paper.

Tidal Flats Morphodynamics: A new Conceptual Model to Predict Their Evolution over a Medium-Long Period
Authors: Petti Marco , Pascolo Sara , Bosa Silvia , Bezzi Annelore , Fontolan Giorgio
Published: June 2019

The morphological evolution of tidal flats has been widely investigated in recent years as it represents a very important topic which is highly related to the climate-driven environmental changes. The period over which geomorphological changes can be noted is a multi-year up to pluri-decennial time scale, defined as medium-long period. This work presents a new conceptual model which is able to predict and estimate a limit depth between an erosion condition and a no-erosion condition for tidal flats. The domains of applicability are shallow and confined basins, where tidal flats are characterized by near-horizontal topography, as occurs inside lagoons. The theoretical approach provides a general equation which relates the limit depth of tidal flats to current velocity and critical erosion shear stress. The procedure, followed through to its development, takes into account the important role of the bottom friction dissipation in wind wave generation process for shallow water. The relationship between tidal flat depth, current velocity and critical shear stress is provided in three different configurations, depending on the direction of the wave motion compared to the current. The limit depth compared to the measured depth can suggest if tidal flats tend or not towards an erosion state over a medium-long period. In this sense, the conceptual model provides a relevant contribution to the comprehension of morphodynamics of these important environments. This approach has been validated with its application to a real context and the results are provided in the paper.
Remembrance of Bognár Sándor (1921-2011)
Authors: András Bozsik
Published: June 2019

Dr. Sándor Bognár was a distinguished cultivator of the horticultural entomology and a determining personality of the higher education of Hungarian crop protection. Training of the scientific and extension specialists of Hungarian agricultural entomology would have been unimaginable without him. He was researcher of the Plant Protection Institute, innovator of the crop protection training’s essential and organisational standard at the Horticultural College and Faculty, who sacrificed his life’s work for developing the crop protection and for the tracking of the history of Hungarian crop protection. He dealt with the Pimplinae (Ichneuminidae) at the very beginning of his carrier and later with the difficulties of soil dwelling pests (Elateridae) but he dedicated a lot of time to the pests of rice and the pest-assemblages of fruit trees and grape. It is important to mention his activity on the phytophagous mites, thus one can call him as one of the founders of the Hungarian agricultural acarology. One top of his educational work was the wonderful manual „Agricultural Entomology” written with László Huzián in 1974 and 1979. László Szalay-Marzsó said of this book that it was impossible to write a better one. He has been right. In spite of his advanced age he participated systematically in the conferences in Hungary and shared the knowledge gained during his long life, and the morals and patriotism got from his models and developed considerably.
From Lovrin to Szécsény – remembrance to Béla Lipthay (1892-1974)
Authors: András Bozsik
Published: June 2019

Béla Lipthay lepidopterologist, entomologist, museologist, agriculturist, hussar lieutenant, life-saving Roman Catholic, descendant of the historical family Lipthay de Kisfalud et Lubelle did a long way from his home village Lovrin to Szécsény, the one-time land of his ancestors. His life coincided with the disintegration of the historical Hungary, and the most serious trials of the Hungarian society, culture and spirit. These changes affected him as a member of Hungarian aristocracy many times and in fact wanted to destroy him. The fortune of the ancestors have been swept away by the storms of the wars, confiscated by the beneficiaries of tricky ideas of the new age and decimated by practical swindlers, but the human strength of character, the consciousness, the advantage of education and the with them associated ability, diligence, inventiveness and the sanctuary of faith have remained. All these made him possible to survive, to do his everyday hard creative work, which gained him the affection, the esteem and respect of the people living around him.Protecting his remembrance we evoke his many-sided, altruistic efforts for the Hungarian people and Hungary, and we can contribute to the creation of a better and just world.

Published: June 2019

Изменение в цвете депульпированного зуба – весьма распространенное и многофакторное по этиологии явление, являющееся частой причиной обращения к стоматологу, особенно если потемневший зуб находится в линии улыбки. Цвет зубов, в свою очередь, наряду с их формой и оптическими свойствами, является важнейшим эстетическим критерием современного человека. Одним из способов исправления цвета таких зубов является внутрикоронковое отбеливание. Целью исследования было оценить эффективность внутрикоронкового отбеливания и восстановления флуоресцентных свойств депульпированных зубов в зависимости от типа используемого силлера при эндодонтическом лечении и причин депульпирования. Для изучения эффективности внутрикоронкового отбеливания депульпированных зубов провели отбеливание 194 зубов 190 пациентам, обратившихся в Клинику ВГМУ и на кафедру терапевтической стоматологии с курсом ФПК и ПК УО «ВГМУ» в период 2014–2018 гг. с жалобами на изменение в цвете зубов после эндодонтического лечения. Средний возраст пациентов составил 34,6±8,2 года. Результаты полученных данных свидетельствуют о том, что эффект отбеливания с восстановлением цвета и флуоресцентных свойств до исходных характеристик витального зуба был достигнут у 72 зубов из 194 (37,11%). У 122 зубов (62,89%) необходимого отбеливания и восстановления флуоресценции не произошло. Из них частично отбелилось 68 зубов (35,05%), не отбелилось 54 зуба (27,84%). В зубах, корневые каналы которых были обтурированы материалами на основе эвгенола, цветовые и флуоресцентные параметры восстановлены в 50% случаев. При обтурации корневых каналов депульпированных зубов силлером на основе резорцин-формалина восстановления цвета и флуоресценции не произошло ни в одном из случаев. Зависимости эффективности отбеливания депульпированных зубов от причины, вызвавшей дисколорит, не выявлено. Однако наиболее частой причиной возникновения изменения в цвете депульпированного зуба был осложненный кариес.

Було проведено клінічне обстеження та суб’єктивний аналіз пацієнтів, що звернулися з метою протезування знімними ортопедичними конструкціями. Для визначення соціальної характеристики пацієнтів і рівня їх якості життя та формування індивідуальної анкети-опитувальника були застосовані спеціальні методи дослідження. Стандартизація процедури збору даних забезпечувалася з використанням анкет-опитувальників.

Отримані дані піддавалися процесу шкалювання, перетворюючись в бали. Відповіді на питання оцінювалися за 5-бальною системою. Якість життя пацієнтів за всіма шкалами спеціального опитувальника істотно змінювалась в сторону поліпшення через місяць та пів року після лікування і зберігалася в часі, що пояснює стабільність лікувального ефекту, що визначається правильністю обраної ортопедичної конструкції та якісно проведеним лікуванням.

Таким чином, якість життя пацієнтів являє собою далеко не останню позицію у якісному ортопедичному лікуванні та її необхідно враховувати в практичній діяльності лікарів-стоматологівортопедів.

У 2018 р. стоматологічна спільнота Львова відзначає 190-річчя викладання предмету одонтологія у Львівському університеті. З 1828 р. професор Карл Прокоп Каліґа розпочав викладати у Львові предмет для майбутніх лікарів, а згодом у 1838 році у Відні видав книгу «Хвороби зубів та засоби їх лікування» [1, 5]. У згаданій книзі вперше на наших теренах подано наукове тлумачення важливості догляду та збереження молочних зубів дитини та вплив на розвиток постійних зубів людини.

У подальшому розвиток стоматологічної школи у Львові розвивався за європейськими стандартами. Виокремлення напрямків спеціалізації у стоматології – таких як пародонтологія, ендодонтія, ортодонтія та ін. – розпочався у ХХ ст. Організація і розвиток стоматологічної науки, зокрема ортодонтії ХХ ст. у Львівському національному медичному університеті ім. Данила Галицького, нерозривно пов’язані з професором Покровським Марком Михайловичем, 80-річчя від народження якого відзначається цьогоріч.

Впродовж своєї наукової діяльності професор М.М. Покровський займався такими напрямами наукових досліджень: застосування фізичних та електрофізіологічних методів дослідження в стоматології; удосконалення методів лікування в ортодонтії (біомеханіка, дисталізація та ін.). Професор Покровський підготував 4 кандидатів наук, автор близько 130 наукових і навчальнометодичних праць, серед них 10 авторських свідоцтв на винаходи.

Усе своє життя професор Марк Михайлович Покровський присвятив стоматології, зокрема ортодонтії. Його науковий доробок у цьому напрямку та практичну роботу як лікаря-ортодонта важко переоцінити, оскільки це був час становлення в ХХ ст. ортодонтії як науки не тільки в Україні, а й у світі. Серед спеціалістів цього профілю його вирізняло глибоке розуміння важливості поєднання технічних застосувань у стоматології, врахування механіки та особливостей біологічних процесів організму, бачення перспектив розвитку для отримання оптимальних результатів лікування. Відданість своїй професії як головне кредо у роботі М.М.

Por lo tanto, el interés de este artículo es mostrar la manera en que se articulan las condiciones sociales que contextualizan a la juventud mixteca con los programas de atención focalizados a fin de conocer las condiciones juveniles contemporáneas y aportar referentes etnográficos que contribuyan en la generación de líneas de acción que orienten políticas públicas pertinentes considerando la heterogeneidad de los grupos indígenas juveniles en dicha metrópoli.

En este ensayo se analizarán los principales prejuicios sobre el concepto de paz en función de los derechos humanos, dado que dicho concepto ha sido utilizado para esconder los intereses políticos y las relaciones de poder que subyacen a los conflictos sociales.
CRÓNICAS DE HISTORIAS INMEDIATAS: EL CORRIDO EN EL 68
Authors: Martínez Gutiérrez Luis Guillermo
Published: June 2019

En las ciudades solamente se puede pensar la creación de géneros musicales populares desde la violencia del movimiento migratorio con el que se conforman estas amalgamas capitalistas. Estos éxodos constantes son el punto de partida para poder explicar por qué estas formas musicales surgieron con gran denuedo en el movimiento popular del 68 mexicano de forma casi inusual –una gran producción en poco más de dos meses– y por qué, en medio...
Self-consistent Predictions for LIER-like Emission Lines from Post-AGB Stars

Early-type galaxies (ETGs) frequently show emission from warm ionized gas. These low-ionization emission regions (LIERs) were originally attributed to a central, low-luminosity active galactic nucleus. However, the recent discovery of spatially extended LIER emission suggests ionization by both a central source and an extended component that follows a stellar-like radial distribution. For passively evolving galaxies with old stellar populations, hot post-asymptotic giant branch (AGB) stars are the only viable extended source of ionizing photons. In this work, we present the first prediction of LIER-like emission from post-AGB stars that is based on fully self-consistent models of stellar evolution and photoionization. We show that models where post-AGB stars are the dominant source of ionizing photons reproduce the signatures of nebular emission observed in ETGs, including LIER-like emission line ratios in standard optical diagnostic diagrams and

equivalent widths of the order of 0.1–3

. We test the sensitivity of LIER-like emission to the details of post-AGB models, including the mass loss efficiency and convective mixing efficiency, and show that line strengths are relatively insensitive to variations in post-AGB timescale. Finally, we examine the UV–optical colors of the models and the stellar populations responsible for the UV excess observed in some ETGs. We find that allowing as little as 3% of the horizontal branch population to be uniformly distributed to very high temperatures (30,000 K) produces realistic UV colors for old, quiescent ETGs.

We have monitored nearly a square degree in IC 1396A/Tr 37 over 21 epochs extending over 2014–2016 for sources variable in the JHK bands. In our data, 65% ± 8% of previously identified cluster members show variations, compared with ≲0.3% of field stars. We identify 119 members of Tr 37 on the basis of variability, forming an unbiased sample down to the brown dwarf regime. The K-band luminosity function in Tr 37 is similar to that of IC 348 but shifted to somewhat brighter values, implying that the K- and M-type members of Tr 37 are younger than those in IC 348. We introduce methods to classify the causes of variability, based on behavior in the color–color and color–magnitude diagrams. Accretion hot spots cause larger variations at J than at K with substantial scatter in the diagrams; there are at least a dozen, with the most active resembling EXors. Eleven sources are probably dominated by intervention of dust clumps in their circumstellar disks, with color behavior indicating the presence of grains larger than for interstellar dust, presumably due to grain growth in their disks. Thirteen sources have larger variations at K than at J or H. For 11 of them, the temperature fitted to the variable component is very close to 2000 K, suggesting that the changes in output are caused by turbulence at the inner rim of the circumstellar disk exposing previously protected populations of grains.
Two new species of Amanita sect. Phalloideae from Africa, one of which is devoid of amatoxins and phallotoxins

Published: June 2019

Two new species of Amanitasect.Phalloideae are described from tropical Africa (incl. Madagascar) based on both morphological and molecular (DNA sequence) data. Amanitabweyeyensissp. nov. was collected, associated with Eucalyptus, in Rwanda, Burundi and Tanzania. It is consumed by local people and chemical analyses showed the absence of amatoxins and phallotoxins in the basidiomata. Surprisingly, molecular analysis performed on the same specimens nevertheless demonstrated the presence of the gene sequence encoding for the phallotoxin phallacidin (PHA gene, member of the MSDIN family). The second species, Amanitaharkonenianasp. nov. was collected in Tanzania and Madagascar. It is also characterised by a complete PHA gene sequence and is suspected to be deadly poisonous. Both species clustered together in a well-supported terminal clade in multilocus phylogenetic inferences (including nuclear ribosomal partial LSU and ITS-5.8S, partial tef1-α, rpb2 and β-tubulin genes), considered either individually or concatenated. This, along with the occurrence of other species in sub-Saharan Africa and their phylogenetic relationships, are briefly discussed. Macro- and microscopic descriptions, as well as pictures and line drawings, are presented for both species. An identification key to the African and Madagascan species of Amanitasect.Phalloideae is provided. The differences between the two new species and the closest Phalloideae species are discussed.
Justicia thailandica, a new species of Acanthaceae from Thailand
Authors: Tong Yi , Deng Yunfei
Published: June 2019

A new species of Justicia (Acanthaceae), J.thailandica, is described and illustrated from Thailand. The new species belongs to Justiciasect.Harnieria and is similar to J.quadrifaria and J.championii, but differs on account of the obviously densely white indumentum in the inflorescence bracts and calyx, ovate leaf blades with margin usually entire, spathulate inflorescence bracts and length ratio of calyx to mature capsule. It is assessed to be “Near threatened” (NE) according to IUCN Red List Category and Criteria. Pollen and seed morphology characters are also reported. Species of Justiciasect.Harnieria in Thailand are discussed and a key to the three recognized species is presented.
Les prêtresses d’Artémis à Éphèse ( I er siècle av. J.-C.– III e siècle apr. J.-C.) ou comment faire du neuf en prétendant restaurer un état ancien ?
Authors: Kirbihler François
Published: June 2019

L’article examine les prêtresses d’Artémis à Éphèse entre Auguste et la crise du troisième quart du iii e siècle après J.-C. : plus d’une cinquantaine de titulaires de la fonction sont connues. Les tâches des prêtresses se laissent en partie appréhender par les inscriptions et par le roman de Xénophon d’Éphèse. Il s’agit à partir de Claude ou de Néron d’une prêtrise annuelle exercée par des jeunes filles issues de familles de notables disposant en majorité de la citoyenneté romaine ; la situation sous Auguste et Tibère était en effet différente. La prêtrise principale d’Artémis confiée à une femme ne paraît attestée qu’à partir du début de l’Empire : elle serait consécutive à la disparition du Mégabyze et pourrait être liée à une réforme de l’Artémision par Octavien, sous couvert de restauration d’une situation antérieure à la domination perse sur l’Asie Mineure.
The Denigration and Marginalisation of Women in Philostratus’ Lives of the Sophists
Authors: L. Bowie Ewen
Published: June 2019

Résumé Cet article analyse l’intérêt très limité que Philostrate porte aux femmes dans ses Vies des sophistes ainsi que la teinte majoritairement négative qu’il donne à leurs portraits lorsqu’il les mentionne. De nombreuses femmes apparaissant dans les Vies sont des intrigantes qui jettent le discrédit sur un sophiste. Les parentes des sophistes apparaissent rarement et ne sont presque jamais nommées. Les sources épigraphiques soulignent ce choix de Philostrate d’évincer les femmes de la parenté lorsque la mention d’une femme de rang élevé aurait pu conforter son portrait d’un sophiste. Philostrate, qui est aussi l’auteur d’une biographie en huit livres d’Apollonios de Tyane, figure de sage bâtie sur l’ascétisme et la chasteté, se faisait probablement une idée très différente de la place des femmes dans l’univers de la culture intellectuelle qu’un philosophe comme Plutarque.
Femmes en peinture et gynécées à Séleucie-Zeugma
Authors: Barbet Alix , Lalanne Sophie
Published: June 2019

Plusieurs maisons luxueusement décorées de Séleucie-Zeugma (les maisons 1, 2 et 3) contiennent une pièce dont les murs étaient couverts de tableaux de femmes en pied. Pas moins de douze femmes étaient peintes sur les murs de la pièce P30 de la maison 3. Certaines femmes peuvent être identifiées (Pénélope, Déidamie, l’amazone Prothoé), mais la plupart restent anonymes. Une étude de ces trois pièces, de leur situation dans l’organisation spatiale de chaque maison et de l’identité des femmes représentées nous conduit à penser que ces pièces étaient probablement des gynécées occupés durant la journée par les femmes de l’ oikos .
Mots et outils du tirage au sort en Grèce ancienne
Authors: López-Rabatel Liliane
Published: June 2019

Le processus de mise en œuvre de la démocratie à Athènes au fil des v e et iv e  siècles avant J.-C. s’exprime par la recherche constante d’outils permettant d’accompagner les innovations politiques. La volonté d’accorder à un corps de citoyens élargi une égale chance d’implication dans la vie civique conduit à une organisation subtile des modes de participation et d’expression du peuple. Pour la dévolution des charges publiques le recours au tirage au sort se développe au détriment de l’élection, mais le vote demeure un puissant mode d’arbitrage, aussi bien à l’Assemblée, au Conseil qu’au Tribunal du peuple. Cette contribution a pour objectif de retracer les grandes étapes de l’équipement du tirage au sort à partir de l’étude du lexique utilisé pour le désigner et d’interroger la césure que marque l’apparition du klèrôtèrion , la machine à tirer au sort emblématique de la démocratie. L’examen conjoint des sources textuelles et des vestiges archéologiques conduit dès lors à se poser la question de l’apport de l’archéologie dans la connaissance du fonctionnement de la démocratie athénienne.
Platon, le tirage au sort au fondement de la communauté politique
Authors: Macé Arnaud
Published: June 2019

Platon, à travers les projets constitutionnels qu’il a développés, en particulier dans les Lois , nous révèle que le tirage au sort peut jouer un rôle politique fondamental, plus fondamental à ses yeux que le fait d’y recourir pour désigner les magistratures, comme le fait la démocratie ancienne. Platon s’appuie sur une culture grecque du hasard, qui confère au tirage au sort la double vertu de la sanction divine et de l’établissement de l’égalité des parts reçues entre égaux. La théorie des deux égalités (fondées soit sur l’identité des parts soit sur leur proportionnalité) permet de marginaliser le tirage au sein de la désignation des magistratures, qui doit relever de l’autre égalité, selon un critère de mérite. En revanche, l’attribution par le tirage au sort de parts égales du territoire assure la cohésion de la cité des Lois . Plus encore, la nécessité de penser la cité comme une somme de récipiendaires de parts égales confère à celle-ci son articulation mathématique et sa capacité de mobilisation.
Le tirage au sort civique dans la Rome républicaine et impériale : matériels et techniques
Authors: Bothorel Julie
Published: June 2019

Dans la Rome républicaine et impériale, le tirage au sort ( sors ou sortitio ) est une procédure technique couramment employée par les magistrats de Rome pour distribuer des tâches particulières parmi les sénateurs ou les magistrats, répartir des lots de terre ou organiser le déroulement du vote. L’étude des sources littéraires, mais également épigraphiques, iconographiques et archéologiques, permet de mieux connaître les instruments qui étaient utilisés pour tirer au sort les lots publics ( sitella, hydria, urna uersatilis, sortes et pilae ), ainsi que la manière dont on les manipulait. Entre les années 100 et 70 av. J.-C., le passage d’un tirage au sort public manuel effectué à l’aide d’une sitella et de sortes à un tirage au sort mécanique effectué à l’aide d’une urna ( uersatilis ) et de pilae illustre les mutations du régime et de l’aristocratie du i er siècle.
Élection ducale, usages institutionnels et pratiques populaires : le tirage au sort dans la République de Venise
Authors: Judde de Larivière Claire
Published: June 2019

La République de Venise occupe une place privilégiée dans l’histoire des usages politiques du tirage au sort, en raison de la procédure utilisée pour l’élection du doge. La complexité du déroulement du vote, qui a depuis longtemps suscité commentaires et interprétations, ne doit pas pour autant faire oublier l’importance de la diffusion du tirage au sort dans la société et les institutions vénitiennes. Cet article montre la diversité des usages de la procédure dans la République de Venise, en envisageant les différents domaines dans lesquels le tirage au sort était employé, en se concentrant sur les manières de faire, de façon à montrer ce que l’ubiquité du tirage au sort révélait de l’idéal politique vénitien qui reposait sur les principes de justice, d’égalité et de distribution des ressources et du pouvoir.
