Medios que sirvan al público
Authors: Fernández Areal Manuel , Martín Algarra Manuel
Published: October 2019

Existe gran confusión sobre lo que haya de entenderse por "servicio público" en materia de Comunicación social. En términos generales, el público suele apreciar como tal servicio el caracterizado por una disposición generalizada a favor del público, la facilidad de acceso a ellos, su gratuidad, el que favorezcan la defensa de los derechos del ciudadano u otros criterios semejantes. Pero una cosa es que los medios, sean de propiedad pública o privada, respondan a los intereses reales del público y otra que el Estado se atibuya en exclusiva su propiedad y su gestión so capa de intereses generales, no siempre bien garantizados. Una concepción estatista del servicio público se mantiene todavía hoy, más o menos solapadamente, en países en los que el Estado trata de justificar su monopolio informativo, o al menos, la obligatoriedad de difundir los mensajes que el gobierno impone.
Origen y evolución de la propaganda política en la España democrática (1975-2000): Análisis de las técnicas y de los mensajes en las elecciones generales del año 2000
Authors: Herrero Julio César , Connolly-Ahern Colleen
Published: October 2019

El presente estudio se centrará en el análisis de las técnicas y mensajes utilizados en la propaganda política difundida por televisión por los principales partidos españoles –Partido Popular (PP) y Partido Socialista Obrero Español (PSOE)– en las elecciones generales del año 2000. Tras exponer cuál es el sistema electoral que rige en España, se esbozarán con brevedad las escasas referencias que existen sobre nuestro tema para, a continuación, explicar la regulación vigente sobre propaganda política en periodo electoral y concluir con el análisis de contenido y la codificación de los spots difundios en el periodo electoral mencionado siguiendo el modelo propuesto por la profesora Lynda Kaid.
Sobre la relación postmoderna entre pensar y obrar y la influencia de los medios de comunicación
Authors: Muñoz-Torres Juan Ramón
Published: October 2019

Las ideas abstractas rigen nuestra actuación cada vez menos. Nuestra manera habitual de actuar –movida más por impulsos y deseos que por juicios teóricos– es la que acaba generando un discurso legitimador de la propia conducta. La mayor parte de los problemas morales contemporáneos son consecuencia, en buena medida, de la crisis del pensamiento, tan característica de la llamada época postmoderna. El presente artículo se propone ofrecer algunas consideraciones respecto a la interacción entre pensamiento y acción propia de la postmodernidad, y de qué manera inciden en ella los medios de comunicación.
El espacio comunicativo en Europa
Authors: Martín Díez María Antonia
Published: October 2019

La integración europea ha ido dando pasos adelante desde el fin de la II Guerra Mundial hasta nuestros días. La comunicación ha sido uno de los instrumentos utilizados para ello. Así por ejemplo, el primer objetivo de la política de comunicación del Consejo de Europa y de la Unión Europea ha sido forjar una identidad común para cuya consecución se han promulgado disposiciones de diverso tipo. A concienciar dicha identidad ha ayudado mucho la irrupción masiva de la tecnología audiovisual y la política audiovisual cuyo carácter global ha mostrado una notable efectividad en diversos campos.
Comunidades virtuales en el ciberespacio
Authors: Valiente Francisco Javier
Published: October 2019

Las nuevas tecnologías de la comunicación están desarrollando nuevas formas de socialización. Alrededor de Internet han ido apareciendo comunidades virtuales que desarrollan sus propias formas de funcionamiento. En el artículo, partiendo de la definición de los términos comunidad y virtual, se señalan las características de este nuevo tipo de socialización y el papel que muchas de estas comunidades pueden jugar en la formación de lo que Pierre Lévy denomina la inteligencia colectiva. Después de presentar una clasificación de las comunidades virtuales, se analizan algunos aspectos que suelen concitar más críticas sobre las relaciones que en estas comunidades se crean como el aislamiento de los individuos, el problema de la identidad y el carácter efímero o la precariedad de las relaciones que en ellas se establecen.
Una propuesta para el estudio de la fotohistoria: el método iconográfico
Authors: Casajús Concha
Published: October 2019

La trascendencia que ha tenido y tiene la fotografía es ya un hecho indiscutible para todos. Vivimos en “el tiempo de la imagen”. Sin embargo, el análisis del significado de las imágenes fijas es una disciplina relativamente nueva a nivel internacional y todavía mucho más reciente a nivel nacional su implantación como asignatura universitaria en España apenas alcanza una década. La problemática deriva de las cantidades ingentes de fotografías, de la ausencia o juventud de las teorías y de los métodos de estudio y de las discrepancias entre teóricos debidas a la escasez de encuentros nacionales e internacionales. Todo ello dificulta el desarrollo de una fotohistoria aceptada por todos. Trato, en este caso, de proponer un método de estudio, el método iconográfico, que, partiendo de los elementos específicos del lenguaje fotográfico y de las necesarias diferencias de tratamiento que imponen los distintos géneros fotográficos, pueda abordar con rigor el problema de la selección y posterior profundización en las imágenes que constituyen la fotohistoria.
La administración comunicativa en España: orígenes de la función de portavoz de gobierno
Authors: Campos Zabala María Victoria
Published: October 2019

El objetivo de este artículo es dar a conocer un periodo fundamental dentro de la historia de la Administración Comunicativa española; los orígenes de la función del Portavoz de Gobierno. Para la reconstrucción del periodo objeto de estudio se ha recurrido a la consulta de fuentes primarias. La investigación marca el inicio de la función de Portavoz de Gobierno en el régimen de Miguel Primo de Rivera. Una vez instaurada la figura de lo que hoy conocemos como Portavoz Gubernamental y, exceptuando el periodo de la Guerra Civil, la función de portavocía gubernamental se ha mantenido en el tiempo.
Ventajas e inconvenientes de la participación radiofónica de la audiencia en los programas de radio
Authors: Herrera Damas Susana
Published: October 2019

Desde los años cuarenta, la participación de los oyentes en los programas de radio ha sido la fórmula participativa que más se ha desarrollado, diversificado y consolidado. No obstante, pese a su versatilidad para las programaciones radiofónicas, lo cierto es que, como cualquier otro elemento programático, esta fórmula tiene también algunos inconvenientes. El presente artículo describe el sentido y contrasentido del empleo de esta fórmula y demanda para el futuro una mayor mediación profesional por parte de quienes realizan los programas, no sólo en la última parte del proceso comunicativo sino desde el mismo diseño y configuración de las programaciones.
La transformación de los usos y funciones de la comunicación pública en el ámbito rural (Estudio de una parroquia gallega)
Authors: Cardoso Jorge
Published: October 2019

En este estudio se analiza cuál es el papel de los medios de comunicación de masas y otras instancias mediadoras en la construcción del acontecer del etnogrupo, es decir, en la construcción de la realidad social y las representaciones culturales de los miembros de la comunidad, en el contexto de un proceso de cambio cultural y de transformación social, de una sociedad tradicional agraria de subsistencia y autoconsumo a una sociedad moderna de formación capitalista. También se analiza cómo esas transformaciones se corresponden con un cambio paralelo en los tipos de sistema de comunicación pública. Los resultados de la investigación prueban algunas leyes subyacentes en la teoría social de la comunicación de Martín Serrano; certifican que la influencia de los mass media es relativa; que la hipótesis de McLuhan respecto a la existencia de una aldea global no es satisfactoria, y que el medio tecnológico no es necesariamente el mensaje, siendo que la mediación depende más de los códigos socioculturales de los miembros del etnogrupo, que de la mera exposición y uso de un determinado instrumento tecnológico.

Abstract. The search for effective drugs for the treatment of infectious diseases of farm animals is an urgent problem. The article presents the models of antipasteurllosis activity of a vast array of chemical compounds, built using descriptors generated by the Dragon program and the computer program PROGROC developed by us. Pasteurelosis is an infectious disease of many species of animals, caused by bacteria of the genus Pasteurella, has a wide geographical distribution and causes significant economic damage to livestock. Treatment of diseased animals with antibiotics is complicated by the emergence of forms of microorganisms that are resistant to them. To solve the problem of bacterial drug resistance, it is proposed to search for and select compounds with antipasteurellosis activity using QSAR (Quantitative Structure-Activity Relationship) methods. To assess the antipasteurellosis activity, the indicator lgMIC (MIC is the minimum inhibitory concentration of the substance) was used. The prediction quality was characterized by a correlation coefficient R between the predicted and experimental values of lgMIC and the standard deviation s. In the present work, models of inhibitory activity against Pasteurella multocida 362 chemical compounds selected at the ChEMBL site were obtained. The simulation involved 445 molecular structure descriptors calculated by the Dragon 7 program. The calculations were performed using the PROGROC computer program (PROGgram RObustness Calculation). The values of the correlation coefficient reached 0.9360–0.9549 for the control sample, where 55–61 % of the total set of substances are represented. When checking the quality of modeling by means of sliding control, the following indicators were obtained: R = 0.9297 and s = 0.40. Calculations were made for compounds with only threshold estimates () in the original database. The obtained estimated lgMIC estimates are in good agreement with the experimental ones, which indicates the possibility of replacing the experiment with less costly calculations.

Authors: Kostyuk Olena , Boychuk Olena
Published: October 2019

Abstract. Introduction. Personal development in competitive and adverseconditions gives us plenty of examples that show negative behavior andincapability of making peace between nations. The situation in the world todayconfirms the previous statement, Ukraine suffers more than many other countriesbecause of the powerful neighbor from the East who forces our country to accepthis conditions. The war in Eastern Ukraine is the consequence of this irrationaland atavistic tendency. We are the victims of the aggravation between twodialectic processes of social activism: disconnection (destructive situations, ATO,loss of a family member, family break up, heightened level of aggression in thecommunity) connection (constructive and creative appearances, adaptation inconditions of forced immigration, posttraumatic growth, resocialization afterovercoming trauma, tendency for reconciliation, personal growth in a newprofession).This is the reality that requires psychological science and practice to find quickand accurate answers because the goal is to save people's mental health in militaryand mobilization conditions.Purpose. The main goal of the research is to generalize the information aboutpsychological features of the people who have experienced loss. Also to spot thestages of women's post-loss resocialization and factors that have a positive impacton that resocialization.Methodology. The authors of this paper made research on the psychologicalfeatures of the people who have experienced loss due to military situation in theEast of Ukraine and who need psychotherapy to help the process ofresocialization.

Conclusions. The facts stated in the paper that helped to analyze the situationwere received during work in the period of 2015-2018 at the center of psycho-social rehabilitation at National University of "Kyiv Mohyla Academy". 5370people have addressed to the center to get help during this period. 1414 of themhave gotten individual consultations, 3953 have participated in group therapies.

Authors: Mulyadi, S.Th.I, M.Ag
Published: October 2019

Tulisan ini ingin memberikan sebuah wawasan inteletual tentang bagaimana konsep manusia dan pengaruhnya terhadap pendidikan Islam dari sudut pandang filsafat pendidikan Islam Syed Muhammad Naquib Al-Attas. Al-Attas mencoba mendeskripsikan manusia untuk menelaah lebih dalam bagaimana konsep yang sesuai untuk pendidikannya. Berangkat dari konsep manusia tersebut, Al-Attas melakukan kritik terhadap konsep pendidikan Barat yang hanya mengedepankan aspek jasmaniah sebagai tolak ukur kesuksesan. Al-Attas menegaskan bahawa manusia adalah mahluk mulia yang terdiri dari ruh (ruh), jiwa (nafs), hati (qalb), dan intelek (‘aql). Oleh sebab itu maka pendidikan Islam harus menyentuh aspek-aspek tersebut secara mendalam untuk menciptkan mansuia sempurna. Proses menciptakan manusia sempurna itu, menurut Al-Attas harus diproses melui konsep pendidikan Islam yang disebut dengan Ta’dîb.

Factors Affecting Immigrant Patients Against Utilization of Health Services at Tamalanrea Health Center
Authors: Qalbi R Nurul , Indar Prof , Rahmatiah Prof
Published: October 2019

Good health care is a community need and is often a measure of development success. The utilization of health service units is still relatively low, although the Puskesmas continue to try to bring health services closer to immigrants. This shows that the lack of confidence of immigrant patients in the health services provided by health workers so that immigrant patients prefer to be referred and continue treatment at the hospital. The purpose of this study is to analyze the factors that influence immigrant patients on the utilization of health services. This research was conducted at Tamalanrea Public Health Center in Makassar City from July-August 2019. The population in this study was 154 people based on data in Tamalanrea Health Center in the last 6 months while the sample in this study was 59 people. Analysis of the data used in this study includes univariate and bivariate analysis stages using multiple regression tests using SPSS version 10. The results of this study indicate that (1) Age has no influence on the utilization of health services, gender has an influence on the utilization of health services in Tamalanrea Health Center ; (2) There is an influence of facilities, and trust in the use of health services with the respective p-value: facilities p = 0.015 and trust p = 0.004. While knowledge has a value of p = 0.665 so that it does not influence the utilization of health services at the Tamalanrea Health Center. The important role of the immigration detection house agency is to help promote and convince immigrants or foreign refugees that first-rate health services can provide the best health services and cure their sickness.

Published: October 2019

Hydrogen gas could provide attractive options as ideal fuel for a world, in which environmental friendly and economically sustainable manner. Microalgae have the ability to bio-synthesis hydrogen gas. Algal H2 does do not generate any toxic or polluting bi-products and could potentially offer value-added products derived from algal biomass. In this work, the feasibility of coupling sulfur deprivation and light on hydrogen production by Chlamydomonas sp grown in photobioreactor was investigated. The cells growth, hydrogen production, total carbohydrate and chlorophyll content were determined. The results showed that, under optimum condition, algae cells were required 168 hr (7days) to reach the late logarithmic phase (the algal dry weight 4.11 g/L). Whereas the algae cells were needed about 18~22 days to reach this value (3.55 g/ L) when grow in optimum medium. The concentration of Chlorophyll (5.65%) and carbohydrate (39.46%) were accumulated in algae cells grow in S-deprives medium coupled with dark condition over that did in algae cells cultured in optimum medium. After about a 24 h of cultivation, photo-production of H2 was observed for C. sp either in absence or presence of sulfate. But under sulfur deprivation coupled with dark condition, higher H2 gas was obtained after 16 hr (7 several days) of incubation period. In new design photobioreactors (PhBRs), after 18 days of cultivation, the volume of H2 gas in was found to be 450 ml in cells grow in sulfur-deprived culture). This value was 360 ml in cells grow under optimal condition.
Social Impacts of the Abaca Bunchy Top Disease and Adaptive Strategies of Farm Households: A Case in Leyte, Philippines
Authors: Nuñez Jedess Miladel
Published: October 2019

The abaca industry is in crisis because of the bunchy-top disease which has destroyed thousands of hectares of abaca ( Musa textilis Nee). While government and research efforts are focused on the eradication of the disease, this study brings attention to the changes in people’s livelihoods and conditions due to the decline of their agricultural and economic productivity as well as their adaptive responses to these impacts and explanations for these. The income loss experienced by households when their crops were destroyed by the combination of the abaca bunchy top disease (ABTD) and inappropriate use of herbicides had secondary impacts to businesses in and near the village. The loss of income led to flow-on impacts on households’ food security, education, health and even psychosocial well-being. However, small landowning households (less than 10ha) were more affected than those with medium-sized farms (10-30ha) in that the changes they experienced were more severe in terms of the quality and quantity of their food and budget for their children’s education. Moreover, households’ access to resources influenced the kind of strategies they employed, with small landowners generally engaged in wage labor, credits and loans and small enterprises to earn income. Medium landowners were generally independent of loans and one such land owner was able to engage in a profitable new enterprise (furniture-making). This case study’s focus shifted from the disease to the affected population and their adaptive responses. Moreover, it looked at the affected population as a stratified society affected by and responding to a disaster differently according to their access to resources.
Peculiarities of cellulose nanoparticles
Authors: IOELOVICH MICHAEL
Published: October 2019

The effects of sulfuric acid concentration and temperature have been studied to optimize the preparation of crystalline nanoparticles (CNP) and amorphous nanoparticles (ANP) of cellulose. To isolate CNP with increased yield (67%-70%) requires hydrolysis with warm 58-60 wt% sulfuric acid. CNP having average sizes of 150 × 15 nm and heightened yield can be obtained by using optimal hydrolysis conditions together with vigorous disintegration. Because of its highly crystalline structure, CNP have increased specific gravity and low hydrophility and accessibility. CNP potentially can be used as a nano-filler to improve properties of pastes, glues, paints, and coating compositions. To isolate ANP having an average diameter of 100 nm with the optimal yield (65-67%), cold 65-66 wt% sulfuric acid should be used in combination with vigorous disintegration. Because of their amorphous structure, ANP acquire such specific features as increased content of functional groups, high accessibility, enhanced sorption ability and hydrophility, and high viscosity and thickening ability. Given the specific features of ANP, their main application area might be for immobilization of biological active substances and drugs, filling and thickening of cosmetic and medicine remedies (e.g., pastes, creams, sprays, etc.).
Measurement of Railway Track Geometry: A State-of-the-Art Review
Authors: Farkas András
Published: October 2019

The worldwide increase in frequency of traffic for passenger trains and the rise of freight trains over the recent years necessitate the more intense deployment of track monitoring and rail inspection procedures. The wheel-rail contact forces, induced by the static axle loads of the vehicle and the dynamic effects of ground-borne vibration coming from the track superstructure, have been a significant factor contributing to the degradation of the railway track system. Measurements of track irregularities have been applied since the early days of railway engineering to reveal the current condition and quality of railway lines. Track geometry is a term used to collectively refer to the measurable parameters including the faults of railway tracks and rails. This paper is aiming to review the characteristics of compact inertial measurement systems (IMUs), their components, installation, the basic measures of the quality of the track using motion sensors, like accelerometers, gyroscopes and other sensing devices mounted on different places of the vehicle. Additionally, the paper briefly discusses the fundamentals of inertial navigation, the kinematics of the translational and rotational train motions to obtain orientation, velocity and position information.

Redefining Home: A Story of Japanese Canadian Resettlement in Toronto explores the story of Harold and Hana Kawasoe, a young Japanese Canadian couple, who chose Toronto as their new home in the face of immeasurable loss they, and many other Japanese Canadians faced during the Second World War. Using a co-curation approach to share the Kawasoe story, the exhibit team discovered how community collaboration and the facilitation of diverse experiences can organically create support and success for museums and historic houses. Redefining Home offers a lens through which the strengths and weaknesses of this method can be seen, and this paper further discusses how it can be implemented by others going forward. Igniting community connections and creating platforms for many voices offers museums valuable and important insight into diverse and unique narratives.

A Critique of Search and Seizure in Terms of a Search Warrant in South African Criminal Procedure: A Comparative Analysis
Authors: Basdeo Vinesh
Published: October 2019

The primary objective of this article is to determine whether the search and seizure measures employed in the South African criminal justice system are in need of any reform and/or augmentation in accordance with the ‘spirit, purport and object’ of the Constitution. This article analyses ‘search and seizure’ in the South African criminal justice system as is made possible by Chapter 2 of the Criminal Procedure Act 51 of 1977, which provides for search warrants, the entering of premises, and the seizure, of property connected with offences. It determines whether the required judicial scrutiny provides a real control upon the exercise of search and seizure powers. Search and seizure legal principles extracted from American criminal procedure will also be analysed for comparative purposes.

Published: October 2019

Remote sensing evapotranspiration estimation over agricultural areas is increasingly used for irrigation management during the crop growing cycle. Different methodologies based on remote sensing have emerged for the leaf area index (LAI) and the canopy chlorophyll content (CCC) estimation, essential biophysical parameters for crop evapotranspiration monitoring. Using Sentinel-2 (S2) spectral information, this study performed a comparative analysis of empirical (vegetation indices), semi-empirical (CLAIR model with fixed and calibrated extinction coefficient) and artificial neural network S2 products derived from the Sentinel Application Platform Software (SNAP) biophysical processor (ANN S2 products) approaches for the estimation of LAI and CCC. Four independent in situ collected datasets of LAI and CCC, obtained with standard instruments (LAI-2000, SPAD) and a smartphone application (PocketLAI), were used. The ANN S2 products present good statistics for LAI (R2 > 0.70, root mean square error (RMSE) < 0.86) and CCC (R2 > 0.75, RMSE < 0.68 g/m2) retrievals. The normalized Sentinel-2 LAI index (SeLI) is the index that presents good statistics in each dataset (R2 > 0.71, RMSE < 0.78) and for the CCC, the ratio red-edge chlorophyll index (CIred-edge) (R2 > 0.67, RMSE < 0.62 g/m2). Both indices use bands located in the red-edge zone, highlighting the importance of this region. The LAI CLAIR model with a fixed extinction coefficient value produces a R2 > 0.63 and a RMSE < 1.47 and calibrating this coefficient for each study area only improves the statistics in two areas (RMSE ≈ 0.70). Finally, this study analyzed the influence of the LAI parameter estimated with the different methodologies in the calculation of crop potential evapotranspiration (ETc) with the adapted Penman–Monteith (FAO-56 PM), using a multi-temporal dataset. The results were compared with ETc estimated as the product of the reference evapotranspiration (ETo) and on the crop coefficient (Kc) derived from FAO table values. In the absence of independent reference ET data, the estimated ETc with the LAI in situ values were considered as the proxy of the ground-truth. ETc estimated with the ANN S2 LAI product is the closest to the ETc values calculated with the LAI in situ (R2 > 0.90, RMSE < 0.41 mm/d). Our findings indicate the good validation of ANN S2 LAI and CCC products and their further suitability for the implementation in evapotranspiration retrieval of agricultural areas.

A major limitation of clinically used cancer drugs is the lack of specificity resulting in toxicity. To address this, we performed a phenotypically-driven screen to identify optimal multidrug combinations acting with high efficacy and selectivity in clear cell renal cell carcinoma (ccRCC). The search was performed using the Therapeutically Guided Multidrug Optimization (TGMO) method in ccRCC cells (786-O) and nonmalignant renal cells and identified a synergistic low-dose four-drug combination (C2) with high efficacy and negligible toxicity. We discovered that C2 inhibits multipolar spindle pole clustering, a survival mechanism employed by cancer cells with spindle abnormalities. This phenotype was also observed in 786-O cells resistant to sunitinib, the first line ccRCC treatment, as well as in melanoma cells with distinct percentages of supernumerary centrosomes. We conclude that C2-treatment shows a high efficacy in cells prone to form multipolar spindles. Our data suggest a highly effective and selective C2 treatment strategy for malignant and drug-resistant cancers.

Published: October 2019

Irrigated production around the world has significantly increased over the last decade. However, climate change is a new threat that could seriously aggravate the irrigation water supplies and request. In this study, the data is derived from the IPCC Fifth Assessment Report (AR5). For the climate change scenarios, five Global Climate Models (GCMs) have been used. By using the CROPWAT approach of Smith, the net irrigation water requirement (IRnet) was calculated. For the estimation of the potential evapotranspiration (Epot), the method in Raziei and Pereira was used. According to representative concentration pathway (RCP) 4.5, these increases vary between 0.74% (North America) and 20.92% (North America) while the RCP 8.5 predict increases of 4.06% (sub-Saharan Africa) to more than 68% (North America). The results also show that the region of Latin America is the region with the large amount of IRnet with coprime value between 1.39 km3/yr (GFDL 4.5) and 1.48 km3/yr (CSIRO 4.5) while sub-Saharan Africa has the smallest IRnet amount between 0.13 km3/yr (GFDL 8.5) and 0.14 km3/yr (ECHAM 8.5). However, the most affected countries by this impact are those in sub-Saharan Africa. This study will probably help decision-makers to make corrections in making their decision.

As a new type of nonlinear electronic component, a memristor can be used in a chaotic system to increase the complexity of the system. In this paper, a flux-controlled memristor is applied to an existing chaotic system, and a novel five-dimensional chaotic system with high complexity and hidden attractors is proposed. Analyzing the nonlinear characteristics of the system, we can find that the system has new chaotic attractors and many novel quasi-periodic limit cycles; the unique attractor structure of the Poincaré map also reflects the complexity and novelty of the hidden attractor for the system; the system has a very high complexity when measured through spectral entropy. In addition, under different initial conditions, the system exhibits the coexistence of chaotic attractors with different topologies, quasi-periodic limit cycles, and chaotic attractors. At the same time, an interesting transient chaos phenomenon, one kind of novel quasi-periodic, and weak chaotic hidden attractors are found. Finally, we realize the memristor model circuit and the proposed chaotic system use off-the-shelf electronic components. The experimental results of the circuit are consistent with the numerical simulation, which shows that the system is physically achievable and provides a new option for the application of memristive chaotic systems.

Power quality problem, because of its various forms and occurrence frequency, has become one of the most critical challenges confronted by a power system. Meanwhile, the development of renewable energy has led to more demands for an integrated system that combines both merits of sustainable energy generation and power quality improvement. In this context, this paper discusses an integrated photovoltaic-unified power quality conditioner (PV-UPQC) and its control strategy. The system is composed of a series compensator, shunt compensator, dc-bus, and photovoltaic array, which conducts an integration of photovoltaic generation and power quality mitigation. The fuzzy adaptive PI controller and the improved Maximum Power Point Tracking (MPPT) technique are proposed to enhance the stability of dc-bus voltage, which is aimed at the power balance and steady operation of the whole system. Additionally, the coordinate control strategy is studied in order to ensure the normal operation and compensation performance of the system under severe voltage sag condition. In comparison to the existing PV-UPQC system, the proposed control method could improve the performance of dc-bus stability and the compensation ability. The dynamic behavior of the integrated system were verified by simulation in MATLAB and PLECS. Selected results are reported to show that the dc-bus voltage was stable and increased under severe situations, which validates the effectiveness of the proposed integrated PV-UPQC system and its control strategy.

The article presents a process of designing the photovoltaic (PHV) converters system for an electric vehicle, shows the scheme of photovoltaic converters usage, the results of electric vehicle motion modeling with photovoltaic converters, and the results of road tests of an electric vehicle with an additional power source based on photovoltaic converters. The photovoltaic converters system and low-voltage system of an electric vehicle have a shared low-voltage battery, which allows the implementation of two schemes of electric vehicle power supply. Initially, the aggregate base was selected, then, taking into account the efficiency of each device included in the design of the new electric vehicle, mathematical modeling was carried out and showed good efficiency results of the photovoltaic converters system. Then, the prototype was manufactured and tested. The aggregate base included the battery of photovoltaic converters assembled in a certain way on the vehicle roof, the MPPT (maximum power point tracking) controller, the buffer storage device in the form of a 12 V battery, and the DC (direct current) converter that allows transmitting electricity from the buffer battery to the high-voltage system. Modeling of the electric vehicle motion considered typical operating modes, including energy costs for the operation of assistant systems of the electric vehicle, as well as including the consumption of low-voltage components. The tests were carried out according to the NEDC (New European Driving Cycle). As a result, implementation of photovoltaic converters with 21% efficiency allowed for the power reserve of the electric vehicle to be increased by up to 9%.

Published: October 2019

The natural convection behaviors of rectangular thermosyphons with different aspect ratios were experimentally analyzed in this study. The experimental model consisted of a loop body, a heating section, a cooling section, and adiabatic sections. The heating and cooling sections were located in the vertical portions of the rectangular loop. The length of the vertical cooling section and the lengths of the upper and lower adiabatic sections were fixed at 300 mm and 200 mm, respectively. The inner diameter of the loop was fixed at 11 mm, and the cooling end temperature was 30 °C. The relevant parameters and their ranges were as follows: The aspect ratios were 6, 4.5, and 3.5 (with potential differences of 41, 27, and 18, respectively, between the cold and hot ends), and the input thermal power ranged from 30 to 60 W (with a heat flux of 600 to 3800 W/m2). The results show that it is feasible to obtain solar heat gain by installing a rectangular thermosyphon inside the metal curtain wall and that increasing the height of the opaque part of the metal curtain wall can increase the aspect ratio of the rectangular thermosyphon installed inside the wall and thus improve the heat transfer efficiency.

Published: October 2019

Reverse osmosis (RO) is a desalination technique that is commonly preferred because of its low energy consumption. In this paper, an innovative, thermally powered RO desalination process is presented. This new thermo-hydraulic process uses solar thermal energy in order to realize the pressurization of the saltwater beyond its osmotic pressure to allow its desalination. This pressurization is enabled thanks to a piston or a membrane set in motion in a reservoir by a working fluid that follows a thermodynamic cycle similar to an Organic Rankine Cycle. In this cycle, the evaporator is heated by low-grade heat, such as the one delivered by flat-plate solar collectors, while the condenser is cooled by the saltwater to be treated. Such an installation, designed for small-scale (1 to 10 m3·day−1) brackish water desalination, should enable an average daily production of 500 L of drinkable water per m² of solar collectors with a specific thermal energy consumption of about 6 kWhth·m−3. A dynamic modeling of the whole process has been developed in order to study its dynamic cyclic operating behavior under variable solar thermal power, to optimize its design, and to maximize its performances. This paper presents the preliminary performance results of such a solar-driven desalination process.

Published: October 2019

Power transformers are important equipment in power systems and their reliability directly concerns the safety of power networks. Dissolved gas analysis (DGA) has shown great potential for detecting the incipient fault of oil-filled power transformers. In order to solve the misdiagnosis problems of traditional fault diagnosis approaches, a novel fault diagnosis method based on hypersphere multiclass support vector machine (HMSVM) and Dempster–Shafer (D–S) Evidence Theory (DET) is proposed. Firstly, proper gas dissolved in oil is selected as the fault characteristic of power transformers. Secondly, HMSVM is employed to diagnose transformer fault with selected characteristics. Then, particle swarm optimization (PSO) is utilized for parameter optimization. Finally, DET is introduced to fuse three different fault diagnosis methods together, including HMSVM, hybrid immune algorithm (HIA), and kernel extreme learning machine (KELM). To avoid the high conflict between different evidences, in this paper, a weight coefficient is introduced for the correction of fusion results. Results indicate that the fault diagnosis based on HMSVM has the highest probability to identify transformer faults among three artificial intelligent approaches. In addition, the improved D–S evidence theory (IDET) combines the advantages of each diagnosis method and promotes fault diagnosis accuracy.

The environmental safety of soil has become a severe problem in China with the boost of industrialization. Polluted-soil thermal remediation is a kind of suitable remediation technology for large-scale heavily contaminated industrial soil, with the advantages of being usable in off-grid areas and with a high fuel to energy conversion rate. Research on energy-saving strategies is beneficial for resource utilization. Focused on energy saving and efficiency promotion of polluted-soil in situ thermal remediation system, this paper presents three energy-saving strategies: Variable-condition mode (VCM), heat-returning mode (HRM) and air-preheating mode (APM). The energy analysis based on the first law of thermodynamics and exergy analysis based on the second law of thermodynamics are completed. By comparing the results, the most effective part of the energy-saving strategy for variable-condition mode is that high savings in the amount of natural gas (NG) used can be achieved, from 0.1124 to 0.0299 kg·s−1 in the first stage. Energy-saving strategies for heat-returning mode and air-preheating mode have higher utilization ratios than the basic method (BM) for the reason they make full use of waste heat. As a whole, a combination of energy-saving strategies can improve the fuel savings and energy efficiency at the same time.
