Campañas institucionales para la prevención del suicidio en España. Análisis del cambio estratégico en su comunicación social: caso Comunidad Valenciana
Authors: Fanjul-Peyró Carlos , González-Oñate Cristina , Santo-Mirabet Marta-del-Carmen
Published: July 2020

La presente investigación trata de dar respuesta a las dudas que genera hablar del suicidio en los medios de comunicación, especialmente ante la escasez de campañas sociales de prevención en el panorama actual. Los datos ofrecidos por la OMS revelan que se trata de un grave problema de salud pública, siendo la segunda causa de muerte en jóvenes entre 15 y 29 años a nivel mundial. Por su parte, los medios muestran rechazo a la hora de tratarlo públicamente debido a la influencia que ejerce el llamado efecto Werther, capaz de generar un efecto “llamada”. Sin embargo, una teoría paralela bajo el nombre de efecto Papageno corrobora que un tratamiento positivo del suicidio en los medios de comunicación puede ayudar a su prevención. Con una recopilación de las principales campañas nacionales, y un análisis de la primera campaña de prevención en la Comunidad Valenciana podemos recoger las fórmulas empleadas para el tratamiento publicitario de un tema de interés público. Visibilizar, sensibilizar y educar son las estrategias a seguir en un futuro. Además, la opinión de los expertos valida este planteamiento y trabajan por una visibilidad pública del fenómeno para acabar con el tabú, el estigma y los mitos que rodean al suicidio.
París 68-Barcelona 77. Del mayo francés a la contracultura española: la evolución de la revista Ajoblanco en la Transición
Authors: Granell Toledo Mónica
Published: July 2020

Mayo del 68 dejó una huella profunda en España en muchos ámbitos y, especialmente, en el de la contracultura española durante el proceso de transición a la democracia tras la muerte del dictador. También acusó su influencia, ya que no habría sido posible sin los acontecimientos de París. En España, uno de los máximos exponentes en este ámbito fue la prensa marginal y, dentro de ella, la revista barcelonesa Ajoblanco, que elaboró una crónica propia del contexto en el que se desarrollaba. En este caso, las reminiscencias de la primavera francesa pronto dejarían paso a una alternativa libertaria, más dedicada a la acción directa, que daría voz a los incipientes movimientos sociales, a la vez que buscaba nuevos referentes europeos. Pero también es verdad que la propia realidad española, a finales de los años setenta, ahogaría las esperanzas abiertas y ahondaría en un proceso de desilusión que se traduciría en «desencanto».

Genetic characterization and phylogenetic study of Lakor goat from Southwest Maluku Regency based on mitochondrial COI gene
Authors: Rumanta Maman , Kunda Rony Marsyal , Volkandari Slamet Diah , Indriawati Indriawati , Kakisina Pieter
Published: June 2020

Aim: This study is aimed at characterizing the genetic and phylogenetic structure of Lakor goats as indigenous livestock from the Southwest Maluku Regency based on mitochondrial COI gene sequences.

Materials and Methods: The genomes of 103 follicle samples from Lakor goats, collected from Lakor Island, were analyzed. The polymerase chain reaction was used to amplify 1548 bp of the mitochondrial COI gene using two primer pairs (COIA and COIB). Following sequencing, genetic variation and phylogenetic relationship were established using MEGA version X software.

Results: The results of multiple COI gene alignment of the total sequences identified four polymorphic nucleotides that function as genetic markers between individual animals within the Lakor goat population. These correspond to positions 228 (A-G), 519 (G-A), 900 (C-T), and 1266 (T-C). Phylogenetic signals based on the COI gene showed that Lakor goat breed is a monophyletic group or single clade with a bootstrap value of 100% by the neighbor-joining (NJ) and maximum likelihood (ML) evolutionary models. This data indicated that evolutionarily, the Lakor goat breed has a very close kinship with three goat breeds from China: The Meigu goat (KM 244714.1), Chinese Tibet (Capra hircus) (KJ 940969.1), and C. hircus (KP 677510.1). Phylogenetic information based on the cladistics system classified the Lakor goat as a single clade (monophyletic group). The low-genetic diversity within populations indicates that there has been an inbreeding depression occurring at a very high frequency.

Conclusion: We conclude that the Lakor goat may be divided into a single clade or monophyletic group based on the COI gene sequence. Four nucleotides were identified that can be used as genetic markers among individual animals within the Lakor goat population, as well as C. hircus and others as derived from GenBank data. The Lakor goat population has a high level of inbreeding depression as a result of geographical isolation, which supports the formation of a monophyletic group with different genetic characteristics, and does not allow the introduction of males from other breeds. Phylogenetic signals indicated that Capra aegagrus (bezoar) is the ancestor of the native goats in Indonesia, including the Lakor goats.

COMPRESSION OF ECAPED TITANIUM MICRO-PILLARS FOR TWO PRINCIPAL ORIENTATIONS
Authors: Vokoun David , Maňák Jan , Tesař Karel , Habr Stanislav
Published: July 2020

The thermomechanical processing by equal-channel angular pressing (ECAP) is used for certain metals and alloys in order to make their structure fine and to increase material strength. In the previous study done at our institute, grade 2 titanium was successfully processed using four consecutive route A passes via a 90 ° ECAP die with high backpressure at room temperature. Orientation dependence of compressive and tensile loading of ECAPed titanium samples was demonstrated at macro-scale. However, scarce attention has been paid so far to the mechanical behavior of ECAPed titanium samples at micro-scale. In the present study, compression experiments on titanium micropillars, fabricated using focused ion beam, are carried out for two main directions in respect to preceding ECAP pressing (insert and extrusion directions). The purpose of this study is to discuss the orientation dependence of mechanical response during compression of the as-ECAPed titanium micro-pillars.
FRACTURE BEHAVIOR OF FeAlSi INTERMETALLICS
Authors: Čech Jaroslav , Haušild Petr , Karlík Miroslav , Nová Kateřina , Průša Filip , Novák Pavel , Kopeček Jaromír
Published: July 2020

The study is devoted to the intermetallic alloy FeAl20Si20 (wt.%) with the potential applications in high temperature aggressive environments. The samples of the same chemical composition were prepared by spark plasma sintering from the different mechanically alloyed powders (pure elements and pre-alloyed powders). Differences in mechanical properties were characterized. Whereas no significant differences were found in hardness and Young´s modulus, fracture resistance was higher for the samples from pre-alloyed powders in which Palmqvist and lateral cracks were observed (contrary to the sample made of pure elements where only Palmqvist cracks were identified).
MICRO-SCALE STUDY OF RESIDUAL STRESSES IN CR2O3 COATINGS SPRAYED BY APS
Authors: Decroos Franck , Langlade Cécile , Bourillot Eric , Darut Geoffrey , Francois Manuel
Published: July 2020

Whichever the application field, every material forming process generates residual stresses on the surface. While they are likely to enhance the aimed properties of the final mechanical part, these stresses may also drastically reduce them and result in early failures. Therefore, understanding the residual stress state remains a major challenge when coating complex parts, especially as most characterization methods at the microscopic scale involve specific sample preparation procedures which may affect the residual stresses field. This work investigates the residual stress state that exists in chromium oxide coatings deposited via Atmospheric Plasma Spray (APS), using two pioneering techniques featuring high spatial resolution: Scanning Microwave Microscopy and Raman Micro-Spectroscopy. The first technique combines the measurement of microwave electromagnetic capacities of a Vector Network Analyzer with the subnanometric resolution of an Atomic Force Microscope: it thus enables performing depth investigations at very accurately defined positions of the probe on the surface. The second technique relies on the principle of photons inelastic scattering and involves a laser beam aiming at the material sample: it allows a fine characterization of the microstructure as well as defects and stresses detection via molecular vibratory signatures. The investigation scale is limited here to a few cubic micrometers. Due to the highly localized scales of our investigations, which also depend on the device, the objective of our procedure required that the comparison should be made not on individual points but on definite mapped areas, every spot being analyzed and post-treated one after another, with optimum measuring parameters. Results have been correlated with XRD measurements to cross-check the average amount of stress observed over a wider area.

Authors: Houdková Šárka , Antoš Jakub , Šulcová Petra , Lencová Kateřina , Hajšman Jan , Burdová Karolína , Duliškovic Josef
Published: July 2020

The wear resistant Mo coatings were deposited using SmartArc Electric Arc Wire Spray System and advanced SinplexPro high throughput atmospheric plasma spray gun. The coatings were analyzed in terms of microstructure, mechanical properties and tribological characteristics, including wear rate and wear mechanism. It was shown that despite of the differences in deposition process principles, the properties of the coatings don’t differ with respect to their functional properties. Both coatings reached comparable hardness, microhardness, wear resistance and coefficient of friction. The economic aspects remain the main argument for the recommendation of the most suitable thermal spray deposition technique for the application of molybdenum coatings.
HARDNESS OF HYBRID PVD-PECVD W-C:H COATINGS VS. SUBSTRATE TYPE
Authors: Lofaj František , Kabátová Margita
Published: July 2020

The effects of substrate on the measurement of hardness (and indentation modulus) - penetration depth profiles were investigated on hybrid PVD-PECVD W-C:H coatings made with the additions of C2H2 or CH4 using High Power Impulse Magnetron Sputtering (HiPIMS) method. The substrates involved 100Cr6 bearing steel, Al2024 aluminum alloy and (111) Si wafer. Although no clear influence of the substrate type on hardness and indentation modulus of the coatings at different acetylene and hydrogen additions was observed, when both measured properties were combined in HITEIT ratio, significant shift of HIT/EIT ratio dependencies obtained on Al alloy vs. steel and Si wafer substrates occurred. Thus, the effect of substrate type on the measurementlevaluation was confirmed.

Oliver Cromwell Cox insisted on dealing with the crucial issues of his time and on telling the truth as he saw it, regardless of whose toes may have been stepped on or whose sensibilities may have been injured. He has aided in preventing the complete stultification of academic social science and in the long run exercised an immense influence on American life.
Marx and Slavery
Authors: Foster John Bellamy , Holleman Hannah , Clark Brett
Published: July 2020

The rise to prominence of analyses of racial capitalism represents a breakthrough in Marxian theory. This has necessarily been accompanied by a critique of previous Marxian analyses, which all too often ignored or minimized the relation of slavery to capitalism. In recent years, however, these criticisms of orthodox Marxist treatments of slavery have been extended, much more problematically, to the work of Karl Marx himself. Although Marx never wrote a treatise on slavery, the issue of slave labor was woven into his analysis of social formations, both ancient and modern, and was inextricably intertwined with his treatment of wage labor.

La pregunta por las condiciones históricas de existencia de los saberes acerca del cuerpo, su lugar en la institución educativa y sus modos de producción –es decir, los momentos en que surgen, y las razones y formas en las que son producidos, instalados, organizados y utilizados– demanda la asunción de la educación como escenario pertinente de indagación para entender las maneras en que la escuela pone en juego discursividades que naturalizan modos específicos de saber acerca del cuerpo.
Sociolinguistic Study of The Horse Image in Some English and Iraqi Arabic Proverbs
Authors: Salman Muhammed B. , Amer Hassan Kh.
Published: July 2020

This research deals with the horse image in some English and Iraqi Arabic proverbs showing how English and Iraqi Arabs interpret, understand, and use these proverbs which include horse image. The selected proverbs are analyzed depending on Holme’s (2013) social factors which are: social distance variable, status variable and formality variable of setting. The English population of the research includes two universities in England. To make the project more applicable, the focus is on Leeds and London universities. The researcher chooses students randomly from “University of Leeds” in Leeds and a university named “London School of Economics and Political Sciences” in London. As for the Iraqi Arabic population, the people who represent the Arabic sample of the current study are from Tikrit and Anbar cities. They are enrolled at “Tikrit University” and “Anbar University” respectively. Among the findings, it is found out that English and Iraqi Arabs have somehow similar connotations concerning the horse image in relation to cultural, occupational, social distance, and formality variables. This denotes that though the two cultures are different, they share some social variables as they have similar connotations for some concepts as in the selected topic. The occupational variable shows that native speakers of both languages indicate that the proverbs which include the horse image are used more frequently by farmers other than other occupations.

Published: July 2020

The aim of this study was to investigate the predictability of global L2 writing performance of Iraqi Kurdistan English as a foreign language (EFL) learners through the affective and linguistic variable of L2 writing anxiety, writing self-efficacy and writing motivation. To this end three types of lingua-affective questionnaires were distributed among 129 EFL learners whose age range was between 18 to 24. They were also required to hand in a writing performance in one session which were scored by two different scorers to have inter-rater reliability. Using a correlational design and running a linear regression test, the researchers investigated the correlation of L2 witting anxiety, writing self-efficacy, writing motivation with global L2 witting performance. The results indicated that writing self-efficacy and writing motivation had a positive and significant relationship with global L2 writing performance while L2 writing anxiety was a different variable from them, indicating a significant but negative correlation with L2 writing performance. The linear regression also indicated that  the sole predicting variable to predict L2 writing performance was observed to be writing motivation and the writing self-efficacy though having a high and significant relationship with L2 writing performance and expected to be among the predictors, did not do this.
W. B. Yeats and the Quest for Order
Authors: Al-Douri Hamdi H.
Published: July 2020

This paper is an attempt to explore Yeats’s quest for order and how this quest found expression in his works. Throughout his life, Yeats was dissatisfied with the religious, artistic, political, anthropological and intellectual aspects of life, in both Ireland and England which have taken away from modern man the sense of order. His father's skepticism, his dissatisfaction with the spiritless religion of his time, a religion which seems dead and his sense of alienation at school among British students were behind his ceaseless search for alternative orders which became the preoccupation of all his life and triggered his [] engagements in numerous nationalistic, occult, and mystical societies which he joined early in his life. Among the societies he joined was the Balvatsky Lodge of the Russian lady Madam Balvatsky through which he came into close contact with the occult. One of the most important societies he joined and presided was the occult society the Golden Dawn. This paper, therefore, sheds light on his quest for nationalist, intellectual, philosophical, and mystical orders and how this is reflected in his poetry. The paper attempts to explore this quest for order selected poems such as "The Lake Isle of Innisfree", "The Second Coming", "Leda and the Swan", "Sailing to Byzantium" and some other poems together with reference to his philosophical book A Vision. However, the dominating quest in Yeats's poetry is his quest for a mystical order which can be traced in almost all his poetical works.

Published: July 2020

The species diversity of climber is found very high in the tropical region of the world. The tropical and sub tropical forests in the Eastern Himalayan state exhibit a good representation of climbing flora. A study on the taxonomic diversity and socio economic importance of climbing plants occurring in Papum Pare district, Arunachal Pradesh was carried out. A total of 187 climbing species were recorded amongst which 61 species distributed over 43 genera and 20 families are found having various economic applications. The detailed ethnobotanical uses and economic importance of all the species were evaluated and presented. Based on their end use, the species are grouped under six broad categories where the highest number of 29 species are found used as local medicines. Additionally, 22 other species were used as wild edibles, 7 species as construction and handicraft materials and 7 species for hunting and fishing. Among all, the species like Piper longum, Abrus precatorius, Calamus tenuis, Dioscorea spp. and Rubia cordifolia have good commercial and economic values. The study revealed that the climbing species are linked with the livelihood as well as for the socio economic support to the local communities. As the majority of the species are used for medicines, fruits and vegetables, the climbing species are found to be playing a vital role in the fulfilment of the medicinal and nutritional requirements of the local people.
Prawo pacjenta do świadczeń zdrowotnych z zakresu lecznictwa uzdrowiskowego
Authors: Jachimowicz-Jankowska Paulina
Published: June 2020

The right to use health services, including spa treatment, is one of the basic patient rights. The specificity of the issues undertaken stems from at least two sources. First of all, patients are a special category of people, because human health, as the highest value possessed by every human being, is subject to legal protection and requires their rights and freedoms are guaranteed. Secondly, spa treatment, which is an integral part of the health care system, corresponds to art. 68 of the Polish Constitution, assuming the fundamental principle according to which every citizen has the right to health care. On the other hand, this treatment means providing health services, which are conducted only in a separate area of the spa commune – a spa and in specially adapted medical entities – spa treatment centers. The study covers the concise genesis of patient rights and the notion of the patient in terms of doctrine and legislation. Moreover, it contains the basic concepts related to spas. Recognition of the health needs of society is associated with a presentation of the individual types of spa treatment centers and spa treatment facilities, as well as the necessary conditions that they should meet. Due to the existing different status of patients in spa treatment institutions, the analysis covers the basis for admission, for referring and qualifying patients to these centers, and also the rules for using services guaranteed in the field of spa treatment. The patient’s right to health services is also examined in the context of using these services. Despite the fact that patients’ interest in this form of treatment increases every year, as is shown by the available data, there are a number of legal and organizational problems related to access to treatment as part of spa services.
Multi-scale In Situ Investigation of Infiltration Parameter in Pervious Concrete Pavements
Authors: Vaddy Poornachandra , Singh Avishreshth , Sampath Prasanna Venkatesh , Biligiri Krishna Prapoorna
Published: June 2020

Embedded infiltration rings have been historically used to estimate the infiltration properties of pervious concrete (PC) pavements. However, no methodical study has evaluated the effect of the size of embedded rings on the infiltration characteristics of these special pavement systems. The objective of this research was to assess the infiltration rate of PC using a multi-scale, in situ approach through embedding rings of various sizes in pavement slabs. Essentially, this investigation attempted to identify the most appropriate size of the embedded ring that can estimate infiltration rates of PC slabs in a reliable manner. To meet the proposed objective, a multi-scale in situ experimental program was designed, in which five infiltration rings of inner diameter ranging from 100 to 580 mm were embedded into three PC slabs of dimensions 3 × 2.5 × 0.15 m. A surface infiltration test was also conducted on PC slabs and was found to vary from 0.36 to 1.87 cm/s. The embedded infiltration rate (EIR) was estimated using a falling head permeability test by ponding water above the pavement surface and measuring the time taken to drain. EIRs decreased from 1.36 to 0.27 cm/s with increasing ring diameter from 100 to 580 mm. Field tests also indicated that infiltration rates for smaller ring diameters (180 mm and lower) had higher uncertainty, which was attributed to the inability of achieving optimum compaction efforts inside of smaller rings. Based on the findings, the optimum size for estimating the infiltration rate of PC was found to be 270 mm. It is noteworthy that this diameter is in the range suggested by ASTM C1701, Standard Test Method for Infiltration Rate of In Place Pervious Concrete, i.e., 300 mm. This research helped identify the practicable specimen size that could be utilized by researchers and practitioners to estimate the most reliable field infiltration rates through PC.
Microstructural Evolution during Sintering and Fracture Behavior of Iron-Copper-Carbon Compacts Made with Elemental Powders
Authors: Murphy Thomas F. , Lindsley Bruce A.
Published: June 2020

Iron-copper and iron-copper-carbon have been significant alloy compositions in the ferrous powder metallurgy industry for decades. In most applications in which these alloys are used, the copper is mixed into an iron or low-alloy steel base powder as an elemental particulate additive, with alloying accomplished by diffusion during sintering. In this manuscript, the effect of sintering on the development of the microstructure is investigated, where the copper particles melt and flow into the interconnected pore structure, relocate within the iron-base matrix, and create more interfacial area for diffusion. With this combination of enlarged copper-iron contact area and the presence of the liquid phase, diffusion is improved and enhancements in both physical and mechanical properties are realized. The mechanisms for both alloying and the evolution of the microstructure are described through changes in both compact temperature and the time at sintering temperature. It is demonstrated that alloying strengthens not only the surfaces of the particles, but also many of the most vulnerable sites in the compact, i.e., the locations where neighboring particles are forced into contact during compaction. These sintered particle-to-particle contacts are frequently small in cross-sectional area and often the weakest sites in the final microstructure. Fractography is used to show the change in fracture behavior as copper diffusion is affected by sintering times and temperatures.
Oxidation Behavior of Microstructurally Different Regions of TIG Weldment in ASTM SA 210 GrA1 Boiler Steel
Authors: Kumar Ravindra
Published: June 2020

ASTM SA 210 GrA1 steel is used for many different applications of steam-generating systems in thermal power plants because of its resistance to corrosion at elevated temperatures and low cost of production. This study examines the oxidation behavior of tungsten inert gas (TIG) weldment in GrA1 boiler steel. Different regions of the weldment were identified by optical microscopy. The oxidation studies were then performed about heat-affected zone (HAZ) and weld metal specimens of TIG weldment after exposure to air at 900°C under cyclic conditions. The thermogravimetric method was applied to observe the kinetics of oxidation. X-ray diffraction and scanning electron microscopy with energy-dispersive X-rays techniques were used to analyze the oxidation product. The HAZ region confirmed the presence of moderately more oxidation (in terms of weight gain of 145.045 mg/cm2) than that of weld metal (139.797 mg/cm2) because the formation of the thick porous oxide scale had internal voids to a high extent.
Design, development, calibration, and testing of indigenously developed strain gauge based dynamometer for cutting force measurement in the milling process
Authors: Mohanraj T. , Shankar S. , Rajasekar R. , Uddin M.S.
Published: June 2020

In this work, a milling dynamometer based on strain gauge with an octagonal and square ring was designed and tested. Strain gauges were attached with the mechanical rings to detect the deformation, during the machining process. Wheatstone bridge circuit was equipped with gauges to acquire the strain as voltage owing to the deformation of mechanical rings when machining takes place. The finite element analysis (FEA) was used to identify the location of maximum deformation and stress. The direction of rings and location of gauges were decided to increase the sensitivity and decrease the cross-sensitivity. Then, the cutting force was acquired through NI 6221 M series data acquisition (DAQ) card. The dynamometer had undergone a cycle of tests to verify its static and dynamic characteristics. The metrological characterization was performed according to the calibration procedure based on ISO 376 – 2011 standard. The cutting force was measured with both the dynamometers through milling experiments based on Taguchi’s L9 orthogonal array and the results were recorded. The measured cutting force varied from 300 N to 550 N. The obtained results depicted that low-cost milling dynamometer was reliable to measure the three component machining force. Overall, the square ring based dynamometer provides the better static and dynamic characteristics in terms of linearity, cross-sensitivity (4%), uncertainty (0.054%), and natural frequency (362.41 rev/s).

Hydraulic turbines need to operate at regimes other than designed ones. Off-design functioning of these turbines yields an inefficient and uneconomical operation of hydro projects. Performance and energy losses at different possible operating conditions need to be evaluated before finalizing the design of water turbines for satisfactory operations. Moreover, hydraulic turbines are unique machines designed for unique set of operating conditions and cost a huge percentage of the overall cost of the project. This work is compiled with twofold objectives; derivation of complete performance characteristics of a 48m head prototype Francis turbine in order to establish an optimum operating regime and, determination and analyses of head loss at different components of the turbine. Steady state flow simulations for four different load operations (60%, 80%, 100% and 120%) have been carried out using computational fluid dynamics. It is found that the optimum regime of operation lies within the speed factor range of 0.412-0.48 along with discharge factor range of 0.27-0.329 and maximum efficiency is obtained as 90.64% at full load operation. Maximum head loss in critical components of the turbine such as runner and draft tube is found as 12.7% at speed factor of 0.568 and 26.31% at 0.202 speed factor respectively. Also, the maximum total head loss in all the components is found as 47.8% at 60% load and 0.609 speed factor. It is concluded that the functioning of the turbine at higher speed factors is more detrimental than that at lower speed factors. Requirement of performance improvement at off-design conditions (especially at 60% load operation) is also suggested in order to widen the range of optimum operating regime. Obtained computational results are validated with experimental results and a strong agreement is found between the two.

Conventionally, the study of convection heat transfer merely focuses on the behavior of air flow without considering the conductive effect of the horizontal flat plate. However, it is expected that the conductive effect of the horizontal plate somewhat affects the air flow temperature across the flat plate. Therefore, it is motivated to study the variation of air flow temperature across different materials of flat plate in various time frame. The materials used in this study are aluminium, stainless steel and cast iron. Infrared camera and FloEFD simulation software are used to measure the upper surface temperature of the flat plate. For forced convection, the study is carried out within the range of 103 £ Re £ 104 and within the range of 1 × 107 £ Ra < 2.2 × 107 for natural convection. Flow velocity of 2.3 m/s, 4.1 m/s and 5.2 m/s are used for the forced convection. The results showed that aluminium plate cools down faster than the other two metal plates used in all scenarios. Stainless steel’s temperature goes down faster compared to cast iron. These results were supported by the fact that aluminium has higher heat transfer rate of other metals. For forced convection, the discrepancies of temperatures between experimental and simulation studies are below 10%, which demonstrates that the results are reasonably acceptable. For natural convection, even though the discrepancies between simulation and experimental results on temperature variations are relatively large, the temperatures varied in similar pattern. This indicates that the results are reliable.

Leading-edge vortex governs the aerodynamic force production of flapping wing flyers. The primary factor for lift enhancement is the leading-edge vortex (LEV) that allows for stall delay that is associated with unsteady fluid flow and thus generating extra lift during flapping flight. To access the effects of LEV to the aerodynamic performance of flapping wing, the three-dimensional numerical analysis of flow solver (FLUENT) are fully applied to simulate the flow pattern. The time-averaged aerodynamic performance (i.e., lift and drag) based on the effect of the advance ratio to the unsteadiness of the flapping wing will result in the flow regime of the flapping wing to be divided into two-state, unsteady state (J<1) and quasi-steady-state(J>1). To access the benefits of aerodynamic to the flapping wing, both set of parameters of velocities 2m/s to 8m/s at a high flapping frequency of 3 to 9 Hz corresponding to three angles of attacks of α = 0o to α = 30o. The result shows that as the advance ratio increases the generated lift and generated decreases until advance ratio, J =3 then the generated lift and drag does not change with increasing advance ratio. It is also found that the change of lift and drag with changing angle of attack changes with increasing advance ratio. At low advance ratio, the lift increase by 61% and the drag increase by 98% between α =100 and α =200. The lift increase by 28% and drag increase by 68% between α = 200 and α = 300. However, at high advance ratio, the lift increase by 59% and the drag increase by 80% between α =100 and α = 200, while between α =200 and α =300 the lift increase by 20% and drag increase by 64%. This suggest that the lift and drag slope decreases with increasing advance ratio. In this research, the results had shown that in the unsteady state flow, the LEV formation can be indicated during both strokes. The LEV is the main factor to the lift enhancement where it generated the lower suction of negative pressure. For unsteady state, the LEV was formed on the upper surface that increases the lift enhancement during downstroke while LEV was formed on the lower surface of the wing that generated the negative lift enhancement. The LEV seem to breakdown at the as the wing flap toward the ends on both strokes.

The angiotensin-converting enzyme 2 (ACE2)/angiotensin 1–7 (A1–7)/MAS axis and glutamate decarboxylase 67 (GAD67)/gamma-aminobutyric acid (GABA) signal both exist in the islet and play important roles in regulating blood glucose metabolism. It has been reported that the activation of ACE2 in the brain increases GABA expression to improve biological effects; however, it is unclear whether there is functional correlation between the ACE2/A1–7/MAS axis and GAD67/GABA signal in the islet. In this study, we showed that the ACE2/A1–7/MAS and GABA signaling systems decreased in the islet of different metabolic stress models. In ACE2-knockout mice, we found that GAD67 and GABA expression decreased significantly, which was reversed by exogenous administration of A1–7. Furthermore, A1–7 mediated PDX1 and AKT activation was inhibited by allylglycine (a specific GAD67 inhibitor) in MIN6 cells. Moreover, giving A1–7 and GABA could significantly reduce beta-cell dedifferentiation and improved glucose metabolism during metabolic stress in vivo and in vitro. In conclusion, our study reveals that the ACE2/A1–7/MAS axis improves beta-cell function through regulating GAD67/GABA signal in beta cells and that up-regulating the ACE2/A1–7/MAS axis and GABA signals delays the development of obesity-induced diabetes.
O traxe rexional na obra narrativa de Emilia Pardo Bazán
Authors: Rodríguez Garabatos Blanca Paula
Published: July 2020

A cultura rural, particularmente a indumentaria, é un elemento narrativo imprescindíbel na obra literaria de Emilia Pardo Bazán. O traxe rexional galego é obxecto de interese antropolóxico por parte da autora (fundadora da Sociedad del Folk-Lore Gallego en 1883 e promotora do cuestionario do folclore galego de 1885), inclinación que a leva a realizar exhaustivas descricións deste tipo de indumentaria tradicional en obras como La gallega, en contos como Eterna Lei e mesmo na súa novelística máis urbana, representada por La Quimera. O seu gusto polo traxe rexional responde a unha dobre finalidade, ofrecer unha visión antropolóxica da vestimenta popular en Galicia e caracterizar tanto os grupos sociais do rural como algúns personaxes inesquecíbeis como Minia en Un destripador de antaño ou Maripepiña en Bucólica.

We establish the exact-order estimates for the approximation of functions from the Nikol'skii-Besov classes $S^{\boldsymbol{r}}_{1,\theta}B(\mathbb{R}^d)$, $d\geq 1$, by entire functions of exponential type with some restrictions for their spectrum. The error of the approximation is estimated in the metric of the Lebesgue space $L_{\infty}(\mathbb{R}^d)$.

Armas de doble filo: el humor en The Fat Black Woman’s Poems y Lazy Thoughts of a Lazy Woman, de Grace Nichols
Authors: Galettini Azucena
Published: July 2020

El segundo y tercer poemario (The Fat Black Woman’s Poems [1984] y Lazy Thoughts of a Lazy Woman [1989], respectivamente) de Grace Nichols, autora guyanesa residente en el Reino Unido desde 1977, se encuentran hermanados por el uso del humor. Criticada por valerse de este recurso, visto como un exceso de liviandad para tratar temas complejos como el pasado de esclavitud, la dura vida del inmigrante caribeño o la sexualidad femenina, Nichols revindica su utilización en tanto implica su adscripción a la tradición antillana. En el presente trabajo, mediante el análisis de cuatro poemas (dos de cada libro), se explora cómo opera el humor en ambas obras y qué simplificaciones conlleva, poniendo especial énfasis en cómo la aparente liviandad que aporta es, en tanto tradición caribeña, otro modo de resistencia.
Ausencia que llama, presencia que responde. Mostrar el vacío, materializar la desaparición forzada: afecto e intimidad en dos documentales centroamericanos
Authors: Gianni Silvia
Published: July 2020

El estudio analiza el tema de la desaparición forzada centroamericana a través del documental de Tatiana Huezo, Ausencias (2015), y el de Marcela Zamora, El cuarto de los huesos (2005). Mi enfoque hace hincapié en el vínculo vivo y dinámico que se establece entre los seres ausentes –los desaparecidos por una de las múltiples formas de violencia que sacude Centroamérica–, los presentes que los esperan y buscan, y los receptores del documental.

Me acerco al trauma y a la memoria por medio del cuerpo, el afecto, las emociones y la intimidad de los familiares de los desaparecidos, ampliando así el abanico de miradas y relatos sobre el trauma y la memoria, de manera tal que el duelo no constituya la única modalidad afectiva con la que reflexionar sobre estos aspectos, sino que represente solo una de las modalidades de la carga afectiva que se desata en la relación entre ausentes, presentes y espectadores.
