Non-Invasive Time-Lapse Imaging of Rainfall Infiltration Levels in the Sedimentary Soils of Central Panama
Authors: A. Ho Carlos , Mojica Alexis , Pinzón Reinhardt , Díaz Irving , Llubes Muriel , Pastor Louis
Published: April 2017

The economic and commercial worldwide impact of the Panama Canal makes this route one of the most important international maritime routes. The quality of water in communities located near the vicinity of the Canal makes conservation and understanding of water resources a priority. In order to identify the stratigraphy and to understand the infiltration processes caused by the rains in the area of Gamboa between the transition (dry to rainy season) and rainy seasons, a time-lapse electrical resistivity tomography analysis was performed. The results showed two horizons constituted mainly by clay material. The first one composed of clay and accumulation of rocks in some areas and the second, the same clay material with certain level of moisture. About the time-lapse results, the negative percent change of resistivity (between 0 and -46.5%) obtained are associated with the rainfall that reached 19 mm during the last days of the second survey; this fact demonstrates the remarkable contribution of the rains to the groundwater that feed the Panama Canal. Moreover, the positive percent change of resistivity (between 0 and 50%) are linked to artefacts which can be common linked to inversion scheme, electrode array or electrode removal and relocation process.

A pandemic of metabolic diseases, consisting of type 2 diabetes, nonalcoholic fatty liver disease, and obesity, has imposed critical challenges for societies worldwide, prompting investigation of underlying mechanisms and exploration of low-cost and effective treatment. In this report, we demonstrate that metabolic disorders in mice generated by feeding with a high-fat diet without dietary vitamin D can be prevented by oral administration of polycationic amine resin. Oral administration of cholestyramine, but not the control uncharged polystyrene, was able to sequester negatively charged bacterial endotoxin in the gut, leading to 1) reduced plasma endotoxin levels, 2) resolved systemic inflammation and hepatic steatohepatitis, and 3) improved insulin sensitivity. Gut dysbiosis, characterized as an increase of the phylum Firmicutes and a decrease of Bacteroidetes and Akkermansia muciniphila, was fully corrected by cholestyramine, indicating that the negatively charged components in the gut are critical for the dysbiosis. Furthermore, fecal bacteria transplant, derived from cholestyramine-treated animals, was sufficient to antagonize the metabolic disorders of the recipient mice. These results indicate that the negatively charged components produced by dysbiosis are critical for biogenesis of metabolic disorders and also show a potential application of cationic polystyrene to treat metabolic disorders through promoting gut eubiosis.

Published: April 2017

OBJECTIVE

Despite the challenges of living with type 1 diabetes, many adolescents achieve “resilient outcomes”: high engagement in self-management behaviors such as self-monitoring of blood glucose (SMBG), good quality of life (QOL), and within-target glycemic outcomes (HbA1c). Adaptive diabetes-related behaviors (i.e., “strengths”) are associated with resilient outcomes, yet the combination of risks and strengths in relation to resilient outcomes is unclear. The aim of this study was to investigate relations among diabetes strengths and resilient outcomes in the context of psychological and family risk factors.

RESEARCH DESIGN AND METHODS

A total of 471 Australian adolescents with type 1 diabetes (mean age 15.7 ± 1.9 years; diabetes duration 6.9 ± 4.2 years; 62% female; 53% using insulin pumps) completed a national cross-sectional survey about their diabetes-related strengths, risk factors (depressive/anxiety symptoms, family conflict), and resilient outcomes (SMBG frequency, general QOL, HbA1c).

RESULTS

Greater diabetes strengths were significantly related to resilient outcomes: more frequent SMBG (r = 0.39), lower HbA1c (r = −0.31), and higher general QOL (r = 0.50), as well as to lower risks: fewer depressive (r = −0.45) and anxiety (r = −0.40) symptoms and less conflict (r = 0.28). In multivariate regressions, diabetes strengths consistently related to all resilient outcomes beyond significant risk factors.

CONCLUSIONS

In a large sample of Australian adolescents, diabetes strengths were strongly related to key resilient outcomes, even in the presence of well-documented psychological and family risk factors. More research is needed to determine whether strengths reduce or buffer other risks. Given the associations with self-management, HbA1c, and general QOL, monitoring and enhancing diabetes strengths may support resilience promotion during a vulnerable developmental period.
Suicide Rates in Greece: Comparing Mortality Data with Police Reporting Statistics and Investigating Recent Trends
Authors: Tragaki Alexandra , Lenos Konstantinos
Published: April 2017

This paper analyzes recent suicide trends in Greece. It relies on two separate databases, vital statistics and police records, the latter never having been explored before. Those datasets present a different picture about the suicide rates and trends, confirming the crucial importance of data reliability and consistency in time trend analysis. Frequencies and ratios were calculated and compared using paired sample t-tests. Overtime trend changes were detected applying segment regression analysis on both data collections. Our findings suggest that there are important differences between vital and police statistics on suicides. At national level, over the period 1990–2013, vital statistics reported an average of 7 percent more suicides, annually. Differences were more pronounced among women and younger ages. Both datasets confirm a change in total suicide trends during recent recession, but police data analysis supports that increases are less impressive than vital statistics claim.

Published: April 2017

Grandparental presence is often found to associate with improved grandchild wellbeing. However, studies have shown that the effect is not always positive. This could be explained by the fact that in some circumstances grandparents compete with grandchildren over parental time resources. We studied the assumption using data from the Program for International Student Assessment (PISA) from 20 Western countries (n=73,346 children at age 15). According to the results grandparental presence was associated with lower levels of parental involvement and decreased educational test scores among adolescents. Moreover, the results indicate that when the parental involvement is lower at the first place the grandparental presence tends to be associated with even weaker child outcomes. Finally, we found support that grandparental co-residence is a mediator of the association between parental involvement and child outcomes. These results are discussed with reference to the local resource competition model.
Natural ventilation strategies for cooling purposes in the rural vernacular architecture of Cyprus
Authors: D. Demosthenous  , A. Michael  , M. Philokyprou
Published: April 2017

The reuse of vernacular dwellings is a sustainable approach, not only because it leaves a small ecological footprint, as opposed to the construction of new buildings, but also because the passive bioclimatic design features of vernacular buildings result in better indoor thermal comfort and in the reduction of energy consumption. This study investigates natural ventilation strategies for cooling purposes in traditional buildings, using exclusively the technique of cross ventilation. The main objective of the present paper is to quantitativelyinvestigate the effectiveness of various naturalventilation strategies, ie., daytime ventilation, full-day (24-hour) ventilation and night ventilation, in the rural vemnacular architecture of Cyprus. In this framework, a field researchstudy was conducted in a representative traditional dwelling in the village of Kapedes, Nicosia, in order to assess the aforementioned ventilation strategies during the hot, summer season. The results show that night ventilation is the most effective strategy for passive cooling in traditional dwellings during the hot summer period, compared to the two other ventilation strategies. The analysis provides evidence that night ventilation reduces indoor temperatures and, consequently, improves the indoor thermal environment of the following day.
Mathematical approach to the characterization of daily energy balance in autonomous photovoltaic solar systems

Published: April 2017

Stochastic simulation methods are normally extended as the only available to assess the reliability of the PV system implies the generation, for an extended period of time, of the main state variables of the physical equations describing the energy balance of the system, that is, the energy delivered to the load and the energy stored in the batteries. Most of these methods consider the daily load as a constant over the year and control the variables indicating the reliability associated with the supply of power to the load. Furthermore, these methods rely on previous random models forgenerating solar radiation data and, since the approximations of the simulation methods are asymptotic, when more precise reliability indicators are required, the simulation period needs to be extended. This paper presents a mathematical methodology to address the daily energy balance without resorting to simulation methods.

PVT-Biomass-Battery systems optimized with evolutionary algorithms for small and highly shaded environments
Authors: J. A. Fernández Fernández  , P. González-Rodelas  , E. Alameda-Hernández
Published: April 2017

When the space where we have to build a PV Solar Plant is not enough to satisfy appropriately the user’s demand, a geometric problem arises in its design. To find the optimal location of the panels, the distances between them, their tilt, or even the number of panels itself, may result in a complex work; much more in small spaces with obstacles near the modules. In these cases, the economically optimal solution(s) is strongly related to these geometric constraints, in addition to the more common variables considered in this type of problems: like electrical loads, or local temperature and cloudiness. This work collects two proposals to mitigate the problem: a Photovoltaic thermal hybrid solar collectors (PVT)-Biomass Battery system which significantly increases the generated energy per square meter; and a computational methodology, based on evolutionary algorithms, to calculate it.

Published: April 2017

The overall energy concept will be the priority matter in the agendas of the various governments in the coming years. The economic prosperity and development of knowledge of nations inevitably depends on energy. For that reason, it is important that institutions establish policies that promote energy sustainability of countries. But their different energy and territorial situation complicate obtaining a suitable model of indicators which could be used to build policies on energy to promote a sustainable development. In short, in this article the fundamental premises are determined to define a indicators model for energy sustainability of countries. Similarly other subsystems about sustainable development are defined. A starting model for the definition of energy policies has been set to take into account all the variables and their relationships.

Published: April 2017

In this paper is presented the procedure adopted by UTE to study the impact of new Photovoltaic (PV) plants connected into the distribution grid. The studies presented focus on harmonic and flicker emissions. In both cases, international standards are used to estimate emissions in the connection node based on data given by the inverter manufacturers. After this, field measurements are performed first before the new PV plant is connected to evaluate the previous state of the grid, and then after the PV plant is connected, to evaluate the actual impact of the plant. All the measurements and the estimated values obtained in the first stage are compared to the limits provided also by international standards. The aim of this paper is to present a real case of the first 8MW PV plant connected to the 31,5kV network in Uruguay, along with the standards and criteria adopted. Finally, a brief comparison between theoretical and real values and their limits is presented.
Assessment of the temperature distribution into a transformer through tensile index
Authors: C. Fernández  , F. Ortiz  , C. Olmo  , J. Carcedo  , A. Ortiz
Published: April 2017

Power transformers are electrical machines which are one of the most critical components in power distribution systems worldwide. Their failure generally is due to the degradation of its insulating system (insulating oil and paper insulation). This deterioration is produced by electrical, mechanical, chemical and thermal stresses which power transformers suffer during their operational lifetime. When dielectric paper has aged severely it loses its tensile strength and its capability to withstand electrical faults decreases considerably. This paper describes an end of life study carried out on a distribution transformer. This analysis has used the tensile index of the dielectric paper to estimate the temperature distribution in the windings of the electric machine. The tensile index is a mechanical parameter associated with the state of the paper insulation that protects the conductors of the windings. By knowing the value of this magnitude for a new and for an aged paper, and the period of operation of a transformer, the temperature distribution along the height of the windings can be estimated. These results and the load rate that a transformer has endured during its life can provide useful information for future designs or for similar transformers still in operation.
Contribution to the knowledge of a microgrid. Smart Campus
Authors: D. Quiroga Alonso  , M. Pérez Donsión
Published: April 2017

From an analysis of electric energy consumption of different buildings of the University of Vigo, it has been designed the integration of a microgrid and its elements, distributed generation, energy storage, security and control systems and applications of a Smart Campus. Distributed generation of electricity is based on the integration of renewable energy sources, especially solar photovoltaic and wind energies, aided by the installation of a hydrogen fuel cell, which is produced out of energetic overproduction of the aforementioned sources by two electrolyzers. In order to avoid the consequences of randomness of wind and solar sources, an energy storage system has been installed. It stores hydrogen produced when overproduction takes place, in order to be able to transform it into electricity when power needs of the microgrid demand it, through a hydrogen fuel cell. Generation and energy storage will be regulated by a security and control system, which will also be responsible for the management and integration of several apps of the Smart Campus. Besides, the implementation in the microgrid of these different apps of the Smart campus, charging spots for electrical cars, parking management, and replacement of conventional lighting by an intelligent and independent system based on renewable energy will be taken into consideration in this study.

Authors: Vita Dra
Published: April 2017

Abstract. The site of Samudera Pasai was the first Islamic kingdom in Indonesia and is located at the coastal area of Aceh Utara (North Aceh) Regency. Due to various natural disasters, the remains of this kingdom are only ruins and only very few physical evidences left. The building remains at this area were perished because the vegetation that protected this coastal area had been damaged by waves, wind, and erosion. Thus far research on environment has not given enough attention, particularly about vegetation in an environment as an effort to protect the Samudera Pasai site. Thus the purpose of writing this article is to know about the condition of the vegetation environment that is one of biotic elements that support the protection and preservation of Samudera Pasai site. This can be known by conducting a vegetation environment survey on the site. Survey results show that the types plants at this area are so diverse, among others mangrove, Casuarina equisetifolia, and a variety of coastal plants. Tree vegetation is also found at the interior part of the site, which is useful to protect the site from physical damage due to the sun and also keep the humidity of the buildings.Abstrak. Situs Samudera Pasai merupakan bekas kerajaan Islam pertama di Indonesia berada di kawasan pesisir pantai Kabupaten Aceh Utara. Akibat dari berbagai bencana yang menimpa situs ini, maka bekas-bekas kerajaan ini hanya tinggal puing dan sangat sedikit bukti fisik yang tersisa. Hilangnya bekas-bekas bangunan di wilayah ini disebabkan oleh punahnya lingkungan vegetasi yang melindungi kawasan pantai dari berbagai bencana seperti deburan ombak, angin, dan erosi pantai. Penelitian tentang lingkungan kurang mendapat perhatian, terutama lingkungan vegetasi sebagai salah satu upaya pendukung perlindungan Situs Samudera Pasai. Oleh karena itu tujuan penulisan naskah ini adalah untuk mengetahui lingkungan vegetasi yang merupakan salah satu unsur biotik pendukung Situs Samudera Pasai untuk melindungi dan melestarikan situs. Hal ini dapat diketahui dengan cara melakukan survei lingkungan vegetasi di situs ini. Hasil survei menunjukkan bahwa berbagai jenis vegetasi tumbuh di sepanjang pantai, antara lain vegetasi bakau (mangrove), vegetasi tanaman cemara (Casuarina equisetifolia), serta vegetasi tanaman pantai dari jenis tumbuhan yang beraneka ragam. Jenis vegetasi pohon ditemukan pula di bagian pedalaman situs, yang bermanfaat untuk melindungi situs dari kehancuran faktor fisik seperti sengatan matahari dan menjaga kelembaban bangunan situs.

Manik-Manik Kaca Salah Satu Indikator Kejayaan Dan Keruntuhan Perniagaan Pulau Kampai.
Authors: Soedewo Ery
Published: April 2017

Salah satu jejak masa lalu di Pulau Kampai yang jumlah dan jenisnya berlimpah adalah manik-manik kaca. Permasalahan pada tulisan ini adalah keterkaitan antara keberlimpahan objek tersebut dengan refleksi kondisi tertentu pada masa lalu di Pulau Kampai. Keberlimpahan data kemudian dianalisis secara morfologi dan dilihat kuantitasnya, sehingga menghasilkan ragam jenis dan gambaran fluktuasi yang merupakan refleksi kejayaan dan keruntuhan perniagaan Pulau Kampai di masa lalu. Penjelasan tentang faktor penyebab fluktuasi dicapai melalui analogi sumber-sumber historis, baik lokal maupun mancanegara. Kajian ini bertujuan menggambarkan fluktuasi perniagaan di Pulau Kampai yang terefleksikan lewat fluktuasi kuantitas manik-manik kacanya, sekaligus menjelaskan faktor penyebab keruntuhan dan kejayaan perniagaan kuna di Pulau Kampai. Kejayaan perniagaan pulau ini berlangsung antara abad ke-11 hingga pertengahan abad ke-14, salah satunya didorong oleh permintaan terhadap produk alam Sumatera oleh pasar Tiongkok sejak masa Dinasti Sung. Keruntuhannya bermula sejak kekuasaan Dinasti Ming membatasi pengusaha swasta dalam perdagangan lintas samudera mulai abad ke-15, yang berakibat pada menurunnya permintaan terhadap produk alam Sumatera. Peran Kampai dalam perniagaan akhirnya mencapai titik terbawah pada abad ke-16 ketika bandar-bandar lain di Sumatera menjadi tempat dijualnya komoditi ekspor yang dihasilkan oleh Aru. Abstract. Kampai Island’s past traces include the abundant varied glass beads. Was such abundant glass beads reflects certain conditions on ancient Kampai Island? Such richness in number and variety have triggered a number of researches on their quantity and morphology which provide some information of categorization and trade fluctuation in the ancient Kampai Island. The factors contributing to the rise and fall of the island are explained through the analogy of local or international historical sources. Kampai’s heyday through AD 11 to the middle of AD 14 centuries was among others due to demand on Sumatera’s natural resources by the Chinese market since the Tang Dynasty’s period; on the other hand, the Ming Dynasty’s AD 15 century inter-ocean private trade quota limitation contributed to the decline of such resources demand. The declining demand finally brought Kampai’s commerce to collapse at AD 16 century when other Sumatera’s ports began to export Aru’s commodity.
