GARCÍA, Leticia Eirín. Visión do Amor no Cancioneiro de Don Denis. Estudo e edición de 33 cantigas de amor. Santiago de Compostela: Laiovento, 2015.
Authors: Mongelli Lênia Márcia
Published: May 2017

Todos os que sabemos das enormes dificuldades que rondam os investigadores comprometidos com edições, individuais ou coletivas, de cantigas da lírica trovadoresca galego-portuguesa só podemos saudar a iniciativa desta jovem Professora da Área de Filologia Galega e Portuguesa da Universidade da Corunha (Galiza), que coloca à disposição do leitor uma parte bem significativa do amplo corpus da produção de El-Rei Don Denis de Portugal (1261-1325), distribuído pelos gêneros canônicos (cantigas de amor, de amigo e de escárnio e maldizer), num total de 137 composições – número expressivo, que dá ao Rei o título unânime de “trovador mais prolífico” dentre os integrantes dos Cancioneiros que chegaram até nós. Como o título da obra anuncia, deste conjunto foi feito um recorte preciso: a cuidadosa edição de 33 cantigas de amor – dentre as 73 deste gênero compostas pelo monarca -, nas quais o motivo da visão (e seus derivados) comparece de forma explícita, como elemento desencadeador de uma série de tormentos, que vão da coita (= sofrimento) ao topos do “morrer d’amor” – espécie de saída desesperada para o amante via de regra ignorado em sua paixão.
Strategies for the electric regulation of pressure control valves
Authors: Giustolisi Orazio , Ugarelli Rita M. , Berardi Luigi , Laucelli Daniele B. , Simone Antonietta
Published: May 2017

In water distribution networks (WDNs), the classic pressure control valves (PCVs) are mechanical/hydraulic devices aimed at maintaining the target pressure just downstream or upstream of the PCV pipe, namely pressure reduction or sustaining valves. From a modelling standpoint, the major drawback of such local control is that classic PCVs may require target pressure varying over time with the pattern of delivered water because the controlled node is not strategic for the optimal WDN pressure control. Current information and communication technology allows transferring streams of pressure data from any WDN node to the PCV. Thus, remotely real-time control (RRTC) permits real-time electric regulation of PCVs to maintain a fixed target pressure value in strategic critical nodes, resulting in optimal control of pressure and background leakages. This paper shows three strategies for the electric regulation of RRTC PCVs, which use as control variables the shutter opening degree (SD), the valve hydraulic resistance (RES) and the valve head loss (HL). The Apulian network is used to compare the three strategies, while the application on the real Oppegård WDN yields further discussions. Results show that HL and RES strategies outperform SD; constraining the maximum shutter displacement helps SD stability although it still needs calibration.
Uncertainty in the analysis of urban water supply and distribution systems
Authors: Tsakiris George , Spiliotis Mike
Published: May 2017

Conventionally, the design of urban water supply and distribution systems is based on the assumption that all the involved parameters are known a priori and remain unaltered throughout the life cycle of the system. However, significant uncertainties do appear during the analysis and design of these systems, such as the equivalent pipe roughness and the actual internal diameters of the pipes. To study these uncertainties, the water supply and the looped water distribution systems are studied separately. For the water supply system, these uncertainties are incorporated in the analysis of the system, using the extension principle of the fuzzy sets and a new operation of the fuzzy subtraction. Based on the calculation of head losses for each branch of the system, the nodal heads are obtained as fuzzy numbers. In regard to the looped water distribution system, a methodology is developed and proposed, based on the extension principle and leading to several optimisation problems with respect to the branches of the system. The aim of the proposed methodology is to determine the α-cuts and finally produce the shape of the membership function of flows in the branches of the system. Both methodologies are illustrated by numerical examples.
New Directions in the Use of Brain Stimulation Interventions in Patients with Obsessive-Compulsive Disorder
Authors: Dell'Osso Bernardo , Cremaschi Laura , Oldani Lucio , Altamura A. Carlo
Published: May 2017

Obsessive-Compulsive Disorder (OCD) is a highly disabling condition with early
onset and chronic course in most of the affected patients. In addition, OCD may show high
comorbidity and suicide attempt rates, which worsen the overall burden of the disease for patients
and their caregivers. First-line treatments for OCD consist of pro-serotonergic compounds
and cognitive-behavioral therapy. Nonetheless, many patients show only limited benefit
from such interventions and require additional “next-step” interventions, including augmentative
antipsychotics and glutamate-modulating agents. Based on the knowledge about
altered neurocircuitry in OCD, brain stimulation techniques, including transcranial magnetic
and electrical stimulations (TMS and tDCS) and deep brain stimulation (DBS), have been increasingly
investigated over the last decade, revealing positive results for otherwise intractable
and treatment-refractory patients. Available evidence in the field is in continuous evolution
and professionals actively involved in the management of OCD patients, psychiatrists in
particular, need to be updated about latest developments. Through the analysis of controlled
studies, meta-analyses, and International treatment guidelines, the present article is aimed at
providing the state of the art on the use of brain stimulation techniques for the treatment of
OCD.

Introduction:

Coronary artery disease (CAD) is a leading cause of death worldwide. The association of socioeconomic status with CAD is supported by numerous epidemiological studies. Whether such factors also impact the number of diseased coronary vessels and its severity is not well established.

Materials and Methods:

We conducted a prospective multicentre, multi-ethnic, cross sectional observational study of consecutive patients undergoing coronary angiography (CAG) at 5 hospitals in the Kingdom of Saudi Arabia and the United Arab Emirates. Baseline demographics, socioeconomic, and clinical variables were collected for all patients. Significant CAD was defined as ≥70% luminal stenosis in a major epicardial vessel. Left main disease (LMD) was defined as ≥50% stenosis in the left main coronary artery. Multi-vessel disease (MVD) was defined as having >1 significant CAD.

Results:

Of 1,068 patients (age 59 ± 13, female 28%, diabetes 56%, hypertension 60%, history of CAD 43%), 792 (74%) were from urban and remainder (26%) from rural communities. Patients from rural centres were older (61 ± 12vs58 ± 13), and more likely to have a history of diabetes (63vs54%), hypertension (74vs55%), dyslipidaemia (78vs59%), CAD (50vs41%) and percutaneous coronary intervention (PCI) (27vs21%). The two groups differed significantly in terms of income level, employment status and indication for angiography. After adjusting for baseline differences, patients living in a rural area were more likely to have significant CAD (adjusted OR 2.40 [1.47, 3.97]), MVD (adjusted OR 1.76 [1.18, 2.63]) and LMD (adjusted OR 1.71 [1.04, 2.82]). Higher income was also associated with a higher risk for significant CAD (adjusted OR 6.97 [2.30, 21.09]) and MVD (adjusted OR 2.49 [1.11, 5.56]), while unemployment was associated with a higher risk of significant CAD (adjusted OR 2.21, [1.27, 3.85]).

Conclusion:

Communal and socioeconomic factors are associated with higher odds of significant CAD and MVD in the group of patients referred for CAG. The underpinnings of these associations (e.g.pathophysiologic factors, access to care, and system-wide determinants of quality) require further study.

Face the most important and beautiful organ of the body is affected by certain anomaly at the any age of the life. Early physical and psychological precautionary measures are essential in either of the sexes, as any minor ailment may affect from unattractive look to a permanent disfigurement, which may result in inferiority complex or sometimes even isolation. The disease Vyanga vis-a-vis Melasma is one of the important disease pertaining to hyper Pigmentation disorders (which mainly affects the glowing complexion of a person by producing Shyava Varna on the face). It is considered under Kshudra Rogas, which occurs mainly due to vitiation of Vata, Pitta and Rakta. The study objective is to evaluate efficacy of Jalauka Avcharan in Vyanga vis–a-vis Melasma. Simple random sampling technique with single group clinical trial is adopted. In the disease Vyanga an important sign is the presence of Niruja, Tanu, Shyava Varnayukta Mandala on Mukhapradesha. Melasma is an asymptomatic, acquired and chronic condition with hyper pigmented macular lesion, develops slowly and symmetrically over molar area, bridge of the nose, forehead and temples and upper lips, more commonly seen in female than male and is not accompanied by inflammation or any other systemic symptoms. In this condition hyper pigmentation is due to increased melanocytes activity in epidermal and dermal layer. Brhajaka Pitta is mainly related to Varna of Twacha. So vitiated Pitta is the main reason behind to cause Vyanga. The parameters show highly significant results with Jalaukavacharana. Among subjective and objective parameters, the parameter size and color shows better effects than the other parameters. The parameter Kandu and Daha also have good effect in this study. Largely all the parameters showed improvement after the treatment. Thus it is fair to conclude that the Jalaukavacharana is effective in Vyanga.

Published: May 2017

From a pilot view through the Ayurvedic Research Scenario, One can see that there are five fields predominantly working upon this agenda. They are academic institutions, Private RandD units, Govt. Ayurvedic Research bodies, Govt. Non Ayurvedic Research bodies and international firms and establishments. But the deficiency in the utilization of outputs of all these works is, there is no concomitant, co-ordinated works and is without central regulations. The lack of co-ordination among these fields reduces the growth rate of our researches. One can’t deny the fact that several researches are having only an eagle eye to commercialise the name “Herbal” and to fill certain pockets. Research scholars with fundamental attitudes towards Ayurveda, are trying to substantiate whole ancient texts and this leads to unidirectional researches and there by satisfying certain hidden political agendas. Lack of productive researches in the fundamental principles will definitely lead to the deterioration of Ayurvedic popularity. Present study cover problems of present Ayurvedic Researches, need of co-ordinate perspective researching planning, need of multi centre researches with long term planning, need of negative studies in the development of science, need of adaptation of current research output in academic syllabus and curriculum.

Traditional approach to health care and cure has been the basic concept of Panchakarma. The Panchakarma is a branch of Ayurveda and one of the oldest health systems in the world with wide acceptance among large segments of the population. Svedana which is a major procedure of Panchakarma acts unanimously as Purvakarma, Pradhana Karma and Pashchat Karma, fight against diseases and becoming more successful in achieving Samyavastha. By its versatility it shows its effectiveness in the diseases of almost all the system by mostly causing vasodilatation and improved general circulation leading to healthy return in the condition. Svedana is considered as Bahirparimarjana Chikitsa and one among the Sad-Upakrama. Svedana which is a major procedure of Panchakarma and it is subdivided into Purvakarma, Pradhana Karma and Pashchat Karma. It is an independent Upakarma, as a Purvakarma measures generally done after Deepana, Pachana and Snehana, before administration of Shodhana treatment, Svedana is a process to induce sweating artificially in a patient who had already undergone Snehana may be or may not be. The heat is generated directly (Saagni) or indirectly (Niragni). Svedana liquefies the Doshas, clears the obstruction of channels of circulation and directs the Doshas to selective places from where they can be expelled easily. In the Vedic era the use of Natural remedies like sun-rays, fire were advocated as remedy in many disorders and mentioned as destroyers of Rakshas i.e. microbes. The current status of Svedana which indicate fluid perspiration from the body by sun light and exercise or the sweating which brought about in the body by contact of heat.

Rol esperado de los psicólogos en la extensión rural en el noreste argentino
Authors: Landini Fernando Pablo
Published: May 2017

La extensión rural es una práctica compleja que involucra asistencia técnica y asesoría a productores y a otros actores rurales, con el fin de que estos puedan fortalecer su producción y sus dinámicas organizativas y comerciales. Vista así, resulta claro que la extensión rural es una práctica interdisciplinaria que requiere contribuciones de las diferentes ciencias sociales. En consecuencia, puede afirmarse que la psicología posee una importante potencialidad para prestar apoyo en la extensión rural. No obstante, se observa que sus contribuciones al área han sido escasas. Así, para comprender el rol potencial de los psicólogos en la extensión rural se realizó una investigación cualitativa, de carácter exploratorio descriptivo, centrada en la realización de cuarenta entrevistas a extensionistas del noreste argentino. Las entrevistas fueron grabadas y luego analizadas, de acuerdo con los principios de la Teoría Fundamentada, mediante el uso del software Atlas Ti. Se concluye que la mayor parte de los extensionistas consideran que la psicología podría apoyar su labor, a pesar de no poder especificar cómo. Se destaca la posibilidad de aportar al manejo de grupos, a la gestión de conflictos y a la comprensión de los productores.

empleados para aumentar su concentración afectan
significativamente el medioambiente y los ecosistemas
del suelo. De acuerdo con la literatura científica, los
microorganismos con potencial biofertilizante han
demostrado poseer diversos mecanismos de acción
para solubilizar estos compuestos y así cumplir con
los requerimientos de las plantas. La presente revisión
sistemática recopila información científica (publicada
entre los años 2004 y 2014) que describe los
mecanismos de acción de los biofertilizantes microbianos
en suelos agrícolas. Se usaron tres bases de

El artículo presenta un panorama histórico de la década de 1930 en el Caribe insular para introducir la situación de Puerto Rico en esos años. Las huelgas cañeras de 1934 fueron la única oportunidad histórica de la clase obrero campesina puertorriqueña de unirse al nacionalismo de Pedro Albizu Campos. Los movimientos del 34 fueron un factor importante que abrió la perspectiva de los trabajadores cañeros hacia otras opciones políticas, como el comunismo y el nacionalismo.
Derechos humanos y ciudadanía en América Latina
Authors: Guerrero Guerrero Ana Luisa
Published: May 2017

En este trabajo se analizan las relaciones entre ciudadanía y derechos humanos en América Latina frente a la era global, desde una perspectiva filosófico-política. La adquisición de los diversos tipos de derechos humanos en América Latina se ha realizado de forma diferente, y con otro orden de aparición que el seguido en la región noroccidental de Norteamérica. Esta situación invita a reflexionar el significado y el sentido que tienen los derechos humanos en Latinoamérica, en la que la presencia de comunidades y minorías étnicas han demandado su derecho a tener derechos humanos, sin olvidar sus condiciones de diversidad cultural y asimetría respecto a la cultura occidental, que ha planteado un paradigma de los derechos humanos que los ha excluido por no asimilarse o convertir a sus miembros en individuos-ciudadanos occidentales.
Sor Juana y el siglo XIX: notas sobre el estudio de Juan María Gutiérrez
Authors: Correa Chiarotti María Guadalupe
Published: May 2017

El artículo estudia las estrategias ideológico-discursivas desplegadas por Juan María Gutiérrez en su ensayo sobre la vida y obra de Sor Juana Inés de la Cruz. Se analiza la lectura que hace un crítico decimonónico de la más grande poeta novohispana, un defensor del credo independentista (y, por lo mismo profundamente antihispánico) de una escritora colonial. En última instancia, lo que se pretende dilucidar es cómo el romanticismo rioplatense asume la conflictiva herencia del virreinato y cómo el ensayo de Gutiérrez se inscribe en el debate en torno a la incorporación de América en el concierto de la cultura occidental.
Los asentamientos ilegales en Colombia: las contradicciones de la economía-mundo capitalista en la sociedad global
Authors: Uribe Castro Hernando
Published: May 2017

La tesis central de este documento gira en torno a esclarecer cómo los asentamientos ilegales, denominados hoy por las autoridades locales como Asentamientos Humanos de Desarrollo Incompleto (Decreto 0419 del 24 de mayo de 1999), son expresiones de tres procesos complejos relacionados: por un lado, son manifestaciones de las contradicciones de las fuerzas del mercado y de las fuerzas del Estado; por otro, son resultado de luchas sociales urbanas lideradas por grupos y comunidades ante el Estado. Y en este sentido, las comunidades exigen del Estado, su principal interlocutor a través de procesos de resolución como la negociación, respuestas que les beneficien y les garanticen la solución a sus problemas de exclusión y marginación.
Las crónicas de viaje de Manuel Gutiérrez Nájera y el discurso cartográfico del porfiriato

The research was conducted in the agroextrativist Nova Esperança community, located on João Pilatos Island in the municipality of Ananindeua/PA. The methodological tools of Participatory Rural Appraisal as the on-site observations, 30 interviews and transect walks were used. The diagnosis revealed that the majority of farmers correspond to the male, to a lesser extent to the female gender. They declared find important to deploy some type of aquaculture farming in their lot, highlighting the most relevant in fish farming. There is a predominance of the exotic Oreochromis niloticus were also identified native species such as Colossoma macropomum and Piaractus brachypomus, and the hybrid "Piaractus mesopotamicus vs Colossoma macropomum” as possible animals for cultivation. Thus, community fish farming activity could be developed by the familiar character of agriculture, such activity can be configured in a possible alternative to strengthening families and the local economy.

Hypovitaminosis A is a nutritional imbalance that occurs in several animal classes, one of which is reptile due to food management error. Beta carotene is a carotenoid, the most important precursor of vitamin A and is found in vegetables. Reptiles do not absorb beta carotene well, so it should be a component of the diet. Vitamin A plays the very important role of maintaining the epithelial tissue of every organism. The clinical signs resulting from this nutritional imbalance in testudines are: squamous metaplasia, hyperkeratosis of the respiratory and ocular epithelia, aural abscess, blepharoedema, peeling of the carapace. The diagnosis is made basically through clinical signs, food history and treatment responsiveness. The treatment instituted is the application of high doses of vitamin A along with adequate nutritional management. This present report describes the case of a Trachemys dorbignyi turtle of 23-year-old tiger, attended at the Silvestre Veterinary Clinic in Goiânia, presenting blepharoedema, carapace desquamation, ataxia, motor incoordination, lethargy, difficulty in locomotion . After an established therapeutic protocol, the animal did not respond to the treatment and died after 11 days of hospitalization. This case report aims to show the importance of nutritional and environmental management in the quality of life of wild and exotic pets.

This study was realized to determine the nutritional value, digestibility of nutrients, apparent digestible protein and metabolizable energy of grain and sunflower meal to slow growth roosters. 15 roosters of Label Rouge were distributed in a completely randomized design with three treatments: reference ration (RR), from which were included 20% (kg/kg) of grain (SG) and sunflower meal (SM). The poultry were housed individually in cages adapted for excreta collection. The apparent digestibility coefficients of by-products, grain and sunflower meal were: 67.09 and 75.88% for dry matter, 24.56 and 28.55% for crude protein, 10.14 and 17.28% for apparent digestible protein, 94.17 and 77.37% for ether extract, 4.27 and 6.61% for neutral detergent fiber, 3.30 and 6.64% for acid detergent fiber, 63.83 and 57.67% for metabolisation coefficient of gross energy, 3945 and 2840 kcal/kg for apparent metabolisable energy and availability of 2.58 and 12.22% for mineral matter. The inclusion of 20% of grain and sunflower meal in diets for slow growth roosters caused a reduction of the apparent digestibility of all nutrients except for ether extract, metabolisation coefficient of gross energy and metabolisable energy, where the grain sunflower showed if higher.

At present, it is remarkable the evident concern with our productive system to attend to the premises of sustainable development, paying attention to the fulfillment of the pillars that base it being of an economic, social and environmental nature. Organomineral fertilizers are a good alternative, being basically composed of a mixture of mineral and organic fertilizers, which present potential for agricultural use, since they tend to have a lower cost in relation to chemical fertilizers, and comes from residues from other productive systems such as Such as the chicken litter, allowing investments in its use and research to meet the growing awareness of production, management and sustainable rural development. The use of organic matter allows a rationalization of the mineral fertilizer, promoting an increase in the cation exchange capacity (T), reducing leach losses and helping to release the nutrients to the plant, contributing to increase productivity. The objective of this work was to verify productivity parameters in relation to the behavior of the use of strictly chemical and conventional fertilization, as opposed to organomineral fertilization, aiming at sustainable development, supply, solubilization and residual effect of nutrients in the soil, reuse of by-products and costs of production.

To evaluate the effect of different additives: Urea, sodium chloride (NaCl), calcium oxide (CaO) and silage inoculant in sugarcane by chemical components and fermentation parameters for the reduction of the ensiled material losses. Silage was prepared with chemical additives and inoculate yourself bacterial, tration 1 (T1) control; tration 2 (T2) sugarcane + 1 % urea; tration 3 (T3) sugarcane 2% NaCl; tration 4 (T4) sugarcane + 2% CaO; tration 5 (T5) sugarcane + Lactobacillus buchneri bacteria. Numerically the lowest values were found with the inoculant Lactobacillus buchneri, the other treatments were satisfactory as the preservation of the ensiled material. It follows that the urea had the best value crude protein (PB), improving the quality of the silage and inhibiting undesirable proliferation of micro-organisms for silage sugarcane.
Is dairy complex a solution to milk safety? A comparison of farmers’ perceived and realized food safety effects
Authors: Wang H. Holly , Yu Hailong , Li Binglong
Published: May 2017

This study explores the major reasons for Chinese small dairy farms to accept the new organization structure, dairy complex (DC), and the discrepancies between the actual effect and farmers’ perceptions. Our results show that the frequency of milk refusal, herd scale and farmers’ age contribute to farmers’ decision in accepting DCs, while sale price and disease prevention do not have significant influence. Independent farmers’ perceived effects and the actual effects of DCs in improving raw milk safety and price are consistent, but there exists misperception of DCs’ effect in disease prevention.

La diabetes mellitus y la hipertensión arterial representan enfermedades crónicas con gran impacto socio-sanitario, no solo por su alta prevalencia, sino también por las complicaciones crónicas que produce y la elevada tasa de mortalidad que tiene. El IMC, la glucemia y la presión arterial elevada junto a la inactividad física y hábitos alimentarios inadecuados constituyen factores predictivos de desarrollo de enfermedad cardiovascular, obesidad, hipertensión arterial y diabetes.
Price convergence patterns across U.S. States
Authors: Christou Christina , Cuñado Juncal , Gupta Rangan
Published: May 2017

This study examines the convergence patterns of prices across 50 U.S. states over the period 1960-2007, by applying the convergence algorithm developed by Peter C. B. Phillips and Donggyu Sul (2007). The empirical findings suggest the rejection of full convergence across the 50 U.S. states? prices, and the presence of 11 subgroups, or convergence clubs. The main implications of this paper point to the low degree of market integration across the U.S. states, the limitations of using a unique national price deflator to calculate real U.S. state variables, and the different effects that national monetary policy decisions will have on U.S. state prices.

Published: May 2017

This paper presents a low cost virtual instrumentation platform. It is used in single-phase systems in order to calculate electric power quantities and indicators defined in IEEE Std. 1459-2010. The algorithm used to calculate the power quantities and indicators are based on synchronous reference frame, which is used to implement the definitions presented in IEEE Std. 1459-2010 under sinusoidal and nonsinusoidal utility conditions. To confirm the theoretical development, experimental results are presented by means of a versatile power monitoring system using a graphic platform, in which the apparent, active and nonactive powers can be viewed and analyzed, as well as the indicators.
Characteristics of Twin-Runner Darreus Water-Turbines for Tidal Current Power Generation

Published: May 2017

In order to make the electrical-power generation feasible under the lower tidal-current condition the twin-runner Darreus water-turbine was developed. The counter rotations of twin runners are expected to increase the power output. In order to find out the best distance between the runners the wind-tunnel tests using the subscale model were carried out. At the dimensionless distance of 0.18 the rotational numbers were increased up to 156 percent of those at the single-runner configuration. With this distance the water-channel test was also conducted. It was confirmed that the revolution numbers of the twin runners were increased by 20 percents of those in the single-runner configuration. The increasing effect of speed by a diffuser was investigated. At the stand-alone test of a diffuser in the wind tunnel the velocity of the current passing through the diffuser was accelerated by 1.1 of the free-stream velocity, however, in the water-channel test the subscale Darreus model with the shorter diffuser showed no increasing effect. This was primarily because of the short length of the diffuser to the mouth distance, which was determined from the standpoint of the structural efficiency. The demonstrative power generation test is planned at the Kanmon strait in March, 2012.
