Authors: Carrillo-Hidalgo Isabel , Pulido-Fernández Juan Ignacio , Mudarra-Fernández Ana Belén
Published: June 2019

Úbeda y Baeza fueron declaradas Ciudades Patrimonio de la Humanidad en 2003. Desde entonces, el turismo en estas ciudades se ha convertido en una actividad clave para su economía y se ha incrementado el número de llegadas en más de un cincuenta por ciento. La gestión de cualquier Ciudad Patrimonio de la Humanidad requiere conocer en profundidad al visitante desde diferentes perspectivas: variables sociodemográficas y psicológicas del turista, características del viaje, actividades llevadas a cabo en el destino, la satisfacción con los recursos de este, así como del gasto realizado por el turista durante el viaje y el presupuesto del que parte.  En concreto, para el caso de Úbeda y Baeza, se ha podido comprobar que el perfil del turista que las visita coincide a grandes rasgos con el del que acude a otras Ciudades Patrimonio de la Humanidad, establecido en la literatura científica, diferenciándose principalmente en variables más específicas relacionadas con el destino y la propia personalidad del turista. Los resultados alcanzados aportan una información de gran utilidad para gestores y policymakers de las Ciudades Patrimonio de la Humanidad, que podrán adaptar su oferta turística al turista que las visita.
Numerical Investigation of Sand-Screen Performance in the Presence of Adhesive Effects for Enhanced Sand Control
Authors: Shaffee Siti Nur , Luckham Paul F. , Matar Omar K. , Karnik Aditya , Zamberi Mohd Shahrul
Published: June 2019

In many industrial processes, an effective particle–filtration system is essential for removing unwanted solids. The oil and gas industry has explored various technologies to control and manage excessive sand production, such as by installing sand screens or injecting consolidation chemicals in sand–prone wells as part of sand–management practices. However, for an unconsolidated sandstone formation, the selection and design of effective sand control remains a challenge. In recent years, the use of a computational technique known as the discrete–element method (DEM) has been explored to gain insight into the various parameters affecting sand–screen–retention behavior and the optimization of various types of sand screens (Mondal et al. 2011, 2012, 2016; Feng et al. 2012; Wu et al. 2016).

In this paper, we investigate the effectiveness of particle filtration using a fully coupled computational–fluid–dynamics (CFD)/DEM approach featuring polydispersed, adhesive solid particles. We found that an increase in particle adhesion reduces the amount of solid in the liquid filtrate that passes through the opening of a wire–wrapped screen, and that a solid pack of particle agglomerates is formed over the screen with time. We also determined that increasing particle adhesion gives rise to a decrease in packing density and a diminished pressure drop across the solid pack covering the screen. This finding is further supported by a Voronoi tessellation analysis, which reveals an increase in porosity of the solid pack with elevated particle adhesion. The results of this study demonstrate that increasing the level of particle agglomeration, such as by using an adhesion–promoting chemical additive, has beneficial effects on particle filtration. An important application of these findings is the design and optimization of sand–control processes for a hydrocarbon well with excessive sand production, which is a major challenge in the oil and gas industry.

Published: June 2019

Background: Elevated level of plasma D-dimer increases the risk of ischemic stroke, stroke severity and progression of stroke status, but the association between plasma D-dimer level and functional outcome is unclear. The aim of this study is to investigate whether Plasma D-dimer level is a determinant of short-term poor functional outcome in patients with acute ischemic stroke (AIS).
Methods: This prospective study included 877 Chinese patients with AIS admitted to Renmin Hospital of Wuhan University within 72 hours of symptom onset. Patients were categorized per plasma D-dimer level: Quartile 1(0.24 mg /L), Quartile 2 (0.25–0.56 mg /L), Quartile 3 (0.57–1.78 mg /L), and Quartile 4 (1.78mg /L). Each patient’s medical record was reviewed, and demographic, clinical, laboratory and neuroimaging information was abstracted. Functional outcome at 90 days was assessed with the modified Rankin Scale (mRS).
Results: Of 877 patients were included (mean age, 64 years; male, 68.5%), poor outcome was present in 302 (34.4%) patients. After adjustment for potential confounding variables, higher plasma D-dimer level on admission was associated with poor outcome (adjusted odds ratio [aOR] 2.257, 95% CI1.349-3.777 for Q4:Q1; P trend = 0.004). According to receiver operating characteristic (ROC) analysis, the best discriminating factor was a plasma D-dimer level 0.315 mg/L for pour outcome [area under the ROC curve (AUC) 0.657; sensitivity 83.8%; specificity 41.4%].
Conclusion: Elevated plasma D-dimer level on admission was significantly associated with increased poor outcome after admission for AIS, suggesting the potential role of plasma D-dimer as a predictive marker for short-term poor outcome in patients with AIS.
In Defence of "Belief"
Authors: Lanman Jonathan A.
Published: June 2019

The cognitive science of religion seeks to explain reli­gious beliefs.  Yet "belief" as a term has been criticised by many anthropologists, psychologists, and philosophers.  The main criti­cisms of "belief" are that beliefs are unobservable, that they do not exist, and that the word ‘belief’ is a western construct unsuitable for comparative use.  All of these criticisms may seem to render a "sci­ence of belief" naïve and mistaken.  Utilizing the work of the cog­nitive sciences, and the philosophical view of functionalism that underlies them, I will offer a minimal definition of belief that will allow for a science of belief and withstand such criticisms.
Conceptualising the Romantic Relationship
Authors: Baćević Jana
Published: June 2019

This paper approaches the phenomenon of the "romantic relationship" as understood within some of the most prominent paradigms in the social sciences. These interpretative frameworks are then applied to the model of the romantic relationship acquired during my own research on the concepts of romantic relationships among young professionals in Belgrade, Serbia. I argue that none of the presented frameworks can be solely relied upon to explain the phenomenon, but that in combination they do offer very valuable insights. This represents an example of how the application of dif­ferent paradigms in social sciences can help to clarify the nature of a phenomenon, rather than representing a ground for contestation.
Television, Rituals, Struggle for Public Memory in Serbia during 1990s
Authors: Erdei Ildiko
Published: June 2019

The aim of the paper is to point to the the role of televi­sion (mainly state owned and controlled) and ritual actions, in creating and distributing messages concerning important social and political events during the 1990s. The main argument is that the ur­ban street political protest actions that were performed by the politi­cal and social opponents of the ruling regime, mainly in Bel­grade streets and squares, were a logical outcome of the regime’s me­dia policy, and closely dependent on it. The aim of that policy was to silence the opposing voices and make them invisible, but also to avoid speaking about events that might threaten the image of the ruling regime as tolerant, peaceful and patriotic, the examples of which were information on war crimes, and devastations of Vukovar, Dubrovnik and Sarajevo. Political protests and ritual ac­tions have created a place where these issues could safely be spoken out, thus creating an emerging public counter sphere. Instead of con­sidering media and rituals as separated ways of communication, it will be showed how in particular social and political context in Ser­bia during 1990s, television and rituals have reached a point of mutual constitution and articulation.

Uncertainty quantification of water age in water supply systems by use of spectral propagation
Authors: Braun Mathias , Piller Olivier , Deuerlein Jochen , Mortazavi Iraj , Iollo Angelo
Published: June 2019

Water distribution networks are critical infrastructures that should ensure the reliable supply of high quality potable water to its users. Numerical models of these networks are generally governed by many parameters for which the exact value is not known. This may be due to a lack of precise knowledge like for consumer demand or due to a lack of accessibility as for the pipe roughness. For network managers, the effect of these uncertainties on the network state is important information that supports them in the decision-making process. This effect is generally evaluated by propagating the uncertainties using the mathematical model. In the past, perturbation, fuzzy and stochastic collocation methods have been used for uncertainty propagation. However, these methods are limited either in the accuracy of the results or the computational effort of the necessary calculations. This paper uses an alternative spectral approach that uses the polynomial chaos expansion and has the potential to give results of comparable accuracy to the Monte Carlo sampling through the definition of a stochastic model. This approach is applied to the hydraulic model of two real networks in order to evaluate the influence of uncertain demands on the water age.
Development of a basin management program to improve water quality in rivers based on an environmental water quality predictive model
Authors: Calvo-Brenes G. , Mora-Molina J.
Published: June 2019

This research has the aim of establishing the amount of land that the Conservation Area National System (SINAC) needs to buy and specifying its use inside the Golfo Dulce Forest Reserve in order to maintain the good quality of the rivers. The study was done inside Rincon sub-basin in the Osa Peninsula, a land dedicated to primary and secondary forest (Melina tree plantations), mangrove forest, urbanism, chaparral, pasture for grazing livestock and crop cultivation, mainly rice and African palm; uses that may change in time affecting the actual water quality (WQ) in rivers and the bay. Changes in land uses modify the WQ and it can be predicted using WQ models based on environmental variables through the evaluation of different scenarios. It was found through modeling that pasture or chaparral land use has no negative impact on WQ; all the contrary happens with increments in crop cultivation or human population. At the present, the coastal area, adjacent to the reserve, has low agricultural activity but that could increase over time, affecting the WQ. Therefore, SINAC should continue with its acquisition land activity to counteract the negative environmental effect of agricultural activity to preserve the actual good quality of the rivers.
Genome-Wide Analysis of Low Dose Bisphenol-A (BPA) Exposure in Human Prostate Cells
Authors: Renaud Ludivine , Huff Matthew , da Silveira Willian A. , Angert Mila , Haas Martin , Hardiman Gary
Published: June 2019

:

Endocrine disrupting compounds (EDCs) have the potential to cause adverse effects on
wildlife and human health. Two important EDCs are the synthetic estrogen 17α-ethynylestradiol
(EE2) and bisphenol-A (BPA) both of which are xenoestrogens (XEs) as they bind the estrogen receptor
and disrupt estrogen physiology in mammals and other vertebrates. In the recent years the influence
of XEs on oncogenes, specifically in relation to breast and prostate cancer has been the subject of
considerable study.

Methodology:

In this study, healthy primary human prostate epithelial cells (PrECs) were exposed to
environmentally relevant concentrations of BPA (5nM and 25nM BPA) and interrogated using a
whole genome microarray.

Results:

Exposure to 5 and 25nM BPA resulted in 7,182 and 7,650 differentially expressed (DE)
genes, respectively in treated PrECs. Exposure to EE2 had the greatest effect on the PrEC transcriptome
(8,891 DE genes).

Conclusion:

We dissected and investigated the nature of the non-estrogenic gene signature associated
with BPA with a focus on transcripts relevant to epigenetic modifications. The expression of transcripts
encoding nuclear hormone receptors as well as histone and DNA methylation, modifying enzymes
were significantly perturbed by exposure to BPA.
PPAR Ligands Containing Stilbene Scaffold
Authors: Fantacuzzi Marialuigia , De Filippis Barbara , Amoroso Rosa , Giampietro Letizia
Published: June 2019

:

Peroxisome proliferator-activated receptors (PPARs) are transcriptional factors which belong
to the ligand-activated nuclear receptor superfamily. They are ubiquitously expressed throughout
the body. So far, three major subtypes have been identified, PPARα, PPARβ/δ and PPARγ. They are
crucial for lipid and glucose metabolism and are also involved in the regulation of several types of tumors,
inflammation, cardiovascular diseases and infertility. The importance of these transcription factors
in physiology and pathophysiology has been largely investigated.

:

Synthetic PPAR ligands are widely used in the treatment of dyslipidemia (e.g. fibrates - PPARα activators)
or in diabetes mellitus (e.g. thiazolidinediones - PPARγ agonists) while a new generation of dual
agonists reveals hypolipemic, hypotensive, antiatherogenic, anti-inflammatory and anticoagulant action.
Many natural ligands, including polyphenolic compounds, influence the expression of these receptors.
They have several health-promoting properties, including antioxidant, anti-inflammatory, and
antineoplastic activities. Resveratrol, a stilbene polyphenol, is a biological active modulator of several
signaling proteins, including PPARs. Given the enormous pharmacological potential of resveratrol,
stilbene-based medicinal chemistry had a rapid increase covering various areas of research.

:

The present review discusses ligands of PPARs that contain stilbene scaffold and summarises the different
types of compounds on the basis of chemical structure.
Efficient FIR Filter Architecture using FPGA
Authors: Jameil Ahmed K. , Ahmed Yassir A. , Albawi Saad
Published: June 2019

Background:

Advance communication systems require new techniques for FIR filters
with resource efficiency in terms of high performance and low power consumption. Lowcomplexity
architectures are required by FIR filters for implementation in field programmable gate
Arrays (FPGA). In addition, FIR filters in multistandard wireless communication systems must have
low complexity and be reconfigurable. The coefficient multipliers of FIR filters are complicated.

Objective:

The implementation and application of high tap FIR filters by a partial product reduce
this complexity. Thus, this article proposes a novel digital finite impulse response (FIR) filter architecture
with FPGA.

Method:

The proposed technique FIR filter is based on a new architecture method and implemented
using the Quartus II design suite manufactured by Altera. Also, the proposed architecture is coded
in Verilog HDL and the code developed from the proposed architecture has been simulated using
Modelsim. This efficient FIR filter architecture is based on the shift and add method. Efficient circuit
techniques are used to further improve power and performance. In addition, the proposed architecture
achieves better hardware requirements as multipliers are reduced. A 10-tap FIR filter is implemented
on the proposed architecture.

Results:

The design’s example demonstrates a 25% reduction in resource usage compared to existing
reconfigurable architectures with FPGA synthesis. In addition, the speed of the proposed architecture
is 37% faster than the best performance of existing methods.

Conclusion:

The proposed architecture offers low power and improved speed with the lowcomplexity
design that gives the best architecture FIR filter for both reconfigurable and fixed applications.

Published: June 2019

UNSTRUCTURED

Studies on the effectiveness of Stress Management Interventions (SMIs) currently lack long-term evaluations. Accordingly, this article addresses questions of how workers who experience SMIs evaluate change after the intervention as well as how SMIs’ implementation can be improved. By processing 50 semi-structured interviews by a qualitative analysis, results indicate that participants perceive themselves as highly engaged and motivated at work. Attributing their engagement at work as a positive coping strategy, the in depth qualitative analysis reveals forms of over-engagement: temporary over-engagement is considered a positive reaction to an increased work demand in the past, it fails to work for the new cumulative stress that workers face. Additionally, identifying four different groups of SMI utilizers, we conclude that specific groups of participants benefit from individualized intervention strategies. SMIs effectiveness increases, both for the individual productivity and for the corporate productivity, when focusing on the individual work engagement and providing individualized interventions.
Improving Pacific Adolescents’ Physical Activity Toward International Recommendations: Exploratory Study of a Digital Education App Coupled With Activity Trackers (Preprint)
Authors: Galy Olivier , Yacef Kalina , Caillaud Corinne
Published: June 2019

BACKGROUND

The prevalence of overweight and obesity in children and adolescents has dramatically increased in the Pacific Island countries and territories over the last decade. Childhood overweight and obesity not only have short-term consequences but are also likely to lead to noncommunicable diseases in adulthood. A major factor contributing to the rising prevalence is an insufficient amount of daily moderate-to-vigorous physical activity (MVPA). In the Pacific region, less than 50% of children and adolescents meet the international recommendations of 11,000 steps and 60 min of MVPA per day. Although studies have shown the potential of digital technologies to change behaviors, none has been proposed to guide adolescents toward achieving these recommendations.

OBJECTIVE

The aims of this study were (1) to investigate whether a technology-based educational program that combines education, objective measures of physical activity (PA), and self-assessment of goal achievement would be well received by Pacific adolescents and help change their PA behaviors toward the international PA recommendations and (2) to create more insightful data analysis methods to better understand PA behavior change.

METHODS

A total of 24 adolescents, aged 12 to 14 years, participated in a 4-week program comprising 8 1-hour modules designed to develop health literacy and physical skills. This self-paced user-centered program was delivered via an app and provided health-related learning content as well as goal setting and self-assessment tasks. PA performed during the 4-week program was captured by an activity tracker to support learning and help the adolescents self-assess their achievements against personal goals. The data were analyzed using a consistency rate and daily behavior clustering to reveal any PA changes, particularly regarding adherence to international recommendations.

RESULTS

The consistency rate of daily steps revealed that the adolescents reached 11,000 steps per day 48% (approximately 3.4 days per week) of the time in the first week of the program, and this peaked at 59% (approximately 4.1 days per week) toward the end of the program. PA data showed an overall increase during the program, particularly in the less active adolescents, who increased their daily steps by 15% and ultimately reached 11,000 steps more frequently. The consistency of daily behavior clustering showed a 27% increase in adherence to international recommendations in the least active adolescents.

CONCLUSIONS

Technology-supported educational programs that include self-monitored PA via activity trackers can be successfully delivered to adolescents in schools in remote Pacific areas. New data mining techniques enable innovative analyses of PA engagement based on the international recommendations.
Valuable Genomes: Taxonomy and Archetypes of Business Models in Direct-to-Consumer Genetic Testing (Preprint)
Authors: Thiebes Scott , Toussaint Philipp A , Ju Jaehyeon , Ahn Jae-Hyeon , Lyytinen Kalle , Sunyaev Ali
Published: June 2019

BACKGROUND

Recent progress in genome data collection and analysis technologies has led to a surge of direct-to-consumer (DTC) genetic testing services. Owing to the clinical value and sensitivity of genomic data, as well as uncertainty and hearsay surrounding business practices of DTC genetic testing service providers, DTC genetic testing has faced significant criticism by researchers and practitioners. Research in this area has centered on ethical and legal implications of providing genetic tests directly to consumers, but we still lack a more profound understanding of how businesses in the DTC genetic testing markets work and provide value to different stakeholders.

OBJECTIVE

The aim of this study was to address the lack of knowledge concerning business models of DTC genetic testing services by systematically identifying the salient properties of various DTC genetic testing service business models as well as discerning dominant business models in the market.

METHODS

We employed a 3-phased research approach. In phase 1, we set up a database of 277 DTC genetic testing services. In phase 2, we drew on these data as well as conceptual models of DTC genetic testing services and iteratively developed a taxonomy of DTC genetic testing service business models. In phase 3, we used a 2-stage clustering method to cluster the 277 services that we identified during phase 1 and derived 6 dominant archetypes of DTC genetic testing service business models.

RESULTS

The contributions of this research are 2-fold. First, we provided a first of its kind, systematically developed taxonomy of DTC genetic testing service business models consisting of 15 dimensions in 4 categories. Each dimension comprises 2 to 5 characteristics and captures relevant aspects of DTC genetic testing service business models. Second, we derived 6 archetypes of DTC genetic testing service business models named as follows: (1) low-cost DTC genomics for enthusiasts, (2) high-privacy DTC genomics for enthusiasts, (3) specific information tests, (4) simple health tests, (5) basic low-value DTC genomics, and (6) comprehensive tests and low data processing.

CONCLUSIONS

Our analysis paints a much more complex business landscape in the DTC genetic testing market than previously anticipated. This calls for further research on business models and their effects that underlie DTC genetic testing services and invites specific regulatory interventions to protect consumers and level the playing field.

Authors: Ho Andy Hau Yan , Tan-Ho Geraldine , Ngo Thuy Anh , Ong Grace , Chong Poh Heng , Dignadice Dennis , Potash Jordan
Published: June 2019

BACKGROUND

End-of-life (EoL) care professionals are at prone to burnout given the intense emotional nature of their work. Previous research supports the efficacy of art therapy in reducing work-related stress and enhancing emotional health among professional EoL caregivers. Integrating mindfulness meditation with art therapy, with reflective awareness complementing emotional expression, has immense potential for self-care and collegial support.

OBJECTIVE

Mindful-Compassion Art Therapy (MCAT) is a novel, empirically-informed and highly structured intervention that aims to reduce work-related stress, cultivate resilience and promote wellness. This study aims to assess the potential effectiveness of MCAT for supporting EoL care professionals in Singapore.

METHODS

An open label waitlist randomized controlled trial. 60 EoL care professionals including doctors, nurses, social workers and personal care workers are randomly allocated to one of two groups: (i) intervention group who receives MCAT immediately, and (ii) waitlist-control group who receives MCAT after intervention group completes treatment. Face-to-face self-administered outcome assessments are collected at three different time points including baseline for both groups, post intervention and 6-week follow-up for intervention group, as well as second baseline and post-intervention for waitlist-control group.

RESULTS

Primary outcome measure includes burnout, and secondary measures include emotional regulation, resilience, compassion, quality of life and death attitudes. Between- and within-participant comparisons of outcomes are conducted and the appropriate effect size estimates reported. An acceptability and feasibility study is to be conducted using a triangulation of qualitative data with framework analysis.

CONCLUSIONS

The outcomes of this study will contribute to advancements in both theories and practices for supporting professional EoL caregivers around the world. It will also inform policy makers about the feasibility, acceptability and effectiveness of delivering a multimodal psycho-socio-spiritual intervention within a community institutional setting. The study has received ethical approval from the Institutional Review Board of Nanyang Technological University.

Published: June 2019

RESUMEN: Los patrones de forrajeo de cuatro especies simpátricas del género Chirostoma (Chirostoma estor, Chirostoma grandocule, Chirostoma attenuatum y Chirostoma patzcuaro) fueron evaluadas en el Lago de Pátzcuaro, para entender la repartición de recursos alimenticios y su coexistencia simpátrica. La abundancia de invertebrados presa fue estimada en distintos hábitat alimenticios y se midieron parámetros físicos y químicos del hábitat en dos sitios de estudio. Los peces fueron recolectados durante las temporadas de lluvias (Septiembre 1987) y estiaje (Marzo 1988); 242 tractos digestivos fueron analizados. Se revaluó el gremio trófico, la selectividad de las presas, la diversidad y el traslape de dieta. Las cuatro especies fueron determinadas como carnívoros depredadores que se alimentan principalmente de necton y perifiton. La diversidad de la dieta y los patrones de selectividad de presas fueron similares entre los atherinopsidos y el traslape de dieta fue >70%. Los resultados no apoyan la propuesta de que la coexistencia de estas cuatro especies se mantiene por medio de la especialización de su dieta. Se hipotetizó que la coexistencia simpátrica de los atherinopsidos del Lago de Pátzcuaro se explica por la alta disponibilidad de recursos alimenticios y la variación ontogénica de su dieta. Este estudio resalta la importancia de analizar los patrones y mecanismos ecológicos como elementos básicos para el diseño de estrategias de conservación en bandadas de especies, bajo efectos antropogénicos como la pérdida del hábitat y la introducción de especies exóticas. Los esfuerzos de conservación son urgentes para preservar el raro proceso evolutivo de la especiación simpátrica (segregación del hábitat) que ocurre en otros lagos del centro de México, y que posiblemente se ha perdido en el Lago de Pátzcuaro, como resultado del manejo deficiente y estrategias de conservación inadecuadas. PALABRAS CLAVE: Atherinopsidae, interacciones alimenticias, bandadas de especies, procesos evolutivos, conservación.
The effects of rain and fallen debris on macroinvertebrate colonization of artificial water tanks and their implications for bromeliad communities
Authors: Monge-Najera Julián , Gename Kyle
Published: June 2019

RESUMEN: Las bromelias son componentes importantes de los bosques tropicales y sus hojas forman tanques con microecosistemas únicos. Hasta hace poco no había estudios experimentales de cómo llegan los macroinvertebrados a esos tanques. Colocamos 150 vasos plásticos ("bromelias artificiales") en un bosque de Costa Rica y hallamos que cuando se evita experimentalmente la caída en ellos de residuos y lluvia, algunos grupos no se encuentran (incluyendo Culicidae, un grupo de importancia médica) o difieren en frecuencia entre tratamiento y control.PALABRAS CLAVE: ecología tropical, experimentos con bromelias, Culicidae en tanques artificiales, Costa Rica, colonización de microhábitats
Daños de la rata Sigmodon hirsutus (Rodentia: Cricetidae) al cultivo de maní (Arachis hypogaea) en Alajuela, Costa Rica

Published: June 2019

RESUMEN: El maní (Arachis hypogaea) es afectado por varios vertebrados pero hay muy pocos estudios sobre este tema en América Central. Evaluamos el daño causado por la rata de campo (Sigmodon hirsutus) durante dos ciclos de producción (2006-2007) en la Estación Experimental Fabio Baudrit, ubicada en La Garita, Alajuela, Costa Rica. Recolectamos roedores cada mes con trampas de golpe. Para el momento de la cosecha se hizo una recolecta completa de la producción en parcelas de 2 y 3 metros de longitud. Se clasificaron las vainas en grandes, medias y pequeñas, y se evaluó el daño causado por los roedores en cada categoría. Las vainas tuvieron pesos promedios de 2,8, 1,8 y 1,1 g  para los tamaños referidos, en el primer ciclo, y de 2,9, 2,1 y 1,3 g para un lote, y de 2,8, 2,1 y 1,3 g para el otro lote en el segundo ciclo. Estimamos una intensidad de daño de 5,28% para el primer ciclo, y ninguno en el segundo ciclo. Concluimos que el daño producido por S. hirsutus se puede reducir al realizar la cosecha en diciembre.  PALABRAS CLAVE: Rata de campo, vertebrados plaga, daños, maní.
Conocimientos y percepción sobre el tabaquismo y sus efectos dañinos a la salud entre los estudiantes adolescentes de Venecia y Aguas Zarcas, Costa Rica
Authors: Bohrer Nick
Published: June 2019

Tobacco addiction represents one of the most grave worldwide public health problems, especially within populations of developing countries. Studies in Costa Rica and other countries demonstrate that this addiction frequently begins during adolescence. This study evaluated with a written questionnaire the general and specific knowledge of 529 students between the ages of 12 and 18 years of the health risks associated with tobacco addiction. It also evaluated their perceptions of the factors that predict the onset of adolescent tobacco addiction. The questionnaire was applied in three of the schools of Venecia and Aguas Zarcas, districts of the San Carlos canton of Costa Rica. The students demonstrated a basic knowledge of the health risks of tobacco addiction on the lungs, pregnancy complications, and cancer. The study indicated a lack of student knowledge of the adverse effects of tobacco on cardiovascular and female reproductive health. There existed a positive linear relation between median knowledge level and age (P≤0,0001; R2=5,45), as well as academic grade (P≤0,0001; R2=10,2). The predictive factors of adolescent tobacco addiction considered the most influential by the students were the influence of smokers within family and friend groups. The implementation of a comprehensive academic program for prevention of tobacco use and addiction that addresses both lack of knowledge and perceptions of these students related to tobacco addiction is recommended.
Phenolic resin derived from Jatropha curcas seed-husk lignin as phenol substitute
Authors: Vega-Aguilar Carlos Alberto , Lutz Giselle , Mata-Segreda Julio F.
Published: June 2019

Phenolic resin derived from Jatropha curcas seed-husk lignin as phenol substitute. A phenolic resin was made, with a fraction of the phenol content substituted by lignin extracted from Jatropha curcas seed husk. The husk was analysed for chemical composition, finding a high quantity of lignin (47% mass fraction). This lignin was extracted using an alkaline pulping method, followed by precipitation with acid. Several lignin-modified phenolic resins were made, using different lignin contents, in mixtures with formaldehyde in alkaline conditions, and curing at 65 ºC for 6 hours. It was noticed that the lignin substitution percentage affects the resin’s mechanical properties, obtaining better results with a 50% substitution. These resins showed good thermal behaviour, electrical insulation properties and good physical stability against water, acidic solutions and organic solvents, but it lacked on stability against alkaline solutions. It is concluded that there is a good opportunity for using the J. curcas seed husk lignin as partial substitute of phenol in phenolic resins, without sacrificing their physicochemical properties. There is a wide range of possibilities on using J. curcas agro-industrial residues as a renewable feedstock.

Authors: Silva Vinícius Fernandes , Bettine Marco
Published: June 2019

Terra em Transe de Glauber Rocha (1967) mostra a realidade da política brasileira “em transe” há 50 anos. Em ano de lembrança e luta dos 50 anos do AI-5 buscamos nesta pesquisa discutir o filme Terra em Transe, como obra central do período do Cinema Novo, que cumpriu e cumpre um papel revelador do período militar, caracterizado pelo estado de exceção e, principalmente, seguindo o pensamento de Giorgio Agamben, pela permanência do estado de exceção em meio ao estado democrático de direito.
Extending operator method to local fractional evolution equations in fluids
Authors: Zhang Sheng , Zhao Sen , Zhang Yue
Published: June 2019

This paper is aimed to solve non-linear local fractional evolution equations
in fluids by extending the operator method proposed by Zenonas Navickas.
Firstly, we give the definitions of the generalized operator of local
fractional differentiation and the multiplicative local fractional operator.
Secondly, some properties of the defined operators are proved. Thirdly, a
solution in the form of operator representation of a local fractional
ordinary differential equation is obtained by the extended operator method.
Finally, with the help of the obtained solution in the form of operator
representation and the fractional complex transform, the local fractional
Kadomtsev-Petviashvili (KP) equation and the fractional
Benjamin-Bona-Mahoney (BBM) equation are solved. It is shown that the
extended operator method can be used for solving some other non-linear local
fractional evolution equations in fluids.
