The Bali bombs and the tourism development cycle

This paper analyses the impact of the Bali bombings on international visitor arrivals in Bali and compares this crisis with previous crises with reference to Butler’s hypothetical tourism area life cycle. The paper demonstrates that the Bali bombings had by far the greatest impact on international tourism visitation than any other crisis in the island’s history. Such was the severity of the decline in Bali that both national and local measures were taken to restore confidence. Important though these measures were, they do not fully account for the strong resurgence in international arrivals, suggesting that the destination has not yet reached consolidation in accordance with Butler’s hypothesis and that the strength of the resurgence owes much to the underlying trend of the development phase associated with the general picture proposed by Butler.

Thalamic paraventricular nucleus lesions facilitate central amygdala neuronal responses to acute psychological stress

The thalamic paraventricular nucleus (PVT) is activated by stress and projects to forebrain structures directly implicated in processing stress-related information. Accordingly, it seems likely the PVT plays an important role in modulating stress responses. We examined effects of excitotoxic PVT lesions on forebrain Fos expression patterns normally elicited by an acute psychological stressor. PVT lesions significantly increased stress-induced Fos in a key stress-processing region, the central amygdala.

Estudo de simulação de reservatórios para o desenvolvimento de um campo do nordeste brasileiro

In the last 16 years emerged in Brazil a segment of independent producers with focus on onshore basins and shallow waters. Among the challenges of these companies is the development of fields with projects with a low net present value (NPV). The objective of this work was to study the technical-economical best option to develop an oil field in the Brazilian Northeast using reservoir simulation. Real geology, reservoir and production data was used to build the geological and simulation model. Due to not having PVT analysis, distillation method test data known as the true boiling points (TBP) were used to create a fluids model generating the PVT data. After execution of the history match, four development scenarios were simulated: the extrapolation of production without new investments, the conversion of a producing well for immiscible gas injection, the drilling of a vertical well and the drilling of a horizontal well. As a result, from the financial point of view, the gas injection is the alternative with lower added value, but it may be viable if there are environmental or regulatory restrictions to flaring or venting the produced gas into the atmosphere from this field or neighboring accumulations. The recovery factor achieved with the drilling of vertical and horizontal wells is similar, but the horizontal well is a project of production acceleration; therefore, the present incremental cumulative production with a minimum rate of company's attractiveness is higher. Depending on the crude oil Brent price and the drilling cost, this option can be technically and financially viable.

Thermal Tracking and Estimation for Microprocessors

Due to increasing integration density and operating frequency of today's high performance processors, the temperature of a typical chip can easily exceed 100 degrees Celsius. However, the runtime thermal state of a chip is very hard to predict and manage due to the random nature in computing workloads, as well as the process, voltage and ambient temperature variability (together called PVT variability). The uneven nature (both in time and space) of the heat dissipation of the chip could lead to severe reliability issues and error-prone chip behavior (e.g. timing errors). Many dynamic power/thermal management techniques have been proposed to address this issue such as dynamic voltage and frequency scaling (DVFS), clock gating and etc. However, most of such techniques require accurate knowledge of the runtime thermal state of the chip to make efficient and effective control decisions. In this work we address the problem of tracking and managing the temperature of microprocessors which include the following sub-problems: (1) how to design an efficient sensor-based thermal tracking system on a given design that could provide accurate real-time temperature feedback; (2) what statistical techniques could be used to estimate the full-chip thermal profile based on very limited (and possibly noise-corrupted) sensor observations; (3) how do we adapt to changes in the underlying system's behavior, since such changes could impact the accuracy of our thermal estimation. The thermal tracking methodology proposed in this work is enabled by on-chip sensors which are already implemented in many modern processors. We first investigate the underlying relationship between heat distribution and power consumption, then we introduce an accurate thermal model for the chip system. Based on this model, we characterize the temperature correlation that exists among different chip modules and explore statistical approaches (such as those based on Kalman filter) that could utilize such correlation to estimate the accurate chip-level thermal profiles in real time. Such estimation is performed based on limited sensor information because sensors are usually resource constrained and noise-corrupted. We also took a further step to extend the standard Kalman filter approach to account for (1) nonlinear effects such as leakage-temperature interdependency and (2) varying statistical characteristics in the underlying system model. The proposed thermal tracking infrastructure and estimation algorithms could consistently generate accurate thermal estimates even when the system is switching among workloads that have very distinct characteristics. Through experiments, our approaches have demonstrated promising results with much higher accuracy compared to existing approaches. Such results can be used to ensure thermal reliability and improve the effectiveness of dynamic thermal management techniques.

THE EFFECT OF ANNEALING ON AMORPHOUS SILICON BASED SOLAR PHOTOVOLTAIC THERMAL SYSTEM (PV/T) AND APPROPRIATE GLOBAL DISPATCH STRATEGIES

Previous work has shown that high-temperature short-term spike thermal annealing of hydrogenated amorphous silicon (a-Si:H) photovoltaic thermal (PVT) systems results in higher electrical energy output. The relationship between temperature and performance of a-Si:H PVT is not simple as high temperatures during thermal annealing improves the immediate electrical performance following an anneal, but during the anneal it creates a marked drop in electrical performance. In addition, the power generation of a-Si:H PVT depends on both the environmental conditions and the Staebler-Wronski Effect kinetics. In order to improve the performance of a-Si:H PVT systems further, this paper reports on the effect of various dispatch strategies on system electrical performance. Utilizing experimental results from thermal annealing, an annealing model simulation for a-Si:Hbased PVT was developed and applied to different cities in the U.S. to investigate potential geographic effects on the dispatch optimization of the overall electrical PVT systems performance and annual electrical yield. The results showed that spike thermal annealing once per day maximized the improved electrical energy generation. In the outdoor operating condition this ideal behavior deteriorates and optimization rules are required to be implemented.

Propuesta de creación de la Reserva Natural Municipal El Chuval en el Municipio de El Retén, Magdalena, Colombia

Colombia se ha comprometido a nivel internacional a realizar acciones que conduzcan al país hacia el desarrollo sostenible, específicamente a proteger los recursos naturales. En línea con esta apuesta, la presente investigación propone la construcción de la Reserva Natural El Chuval, en el municipio El Retén, Magdalena. Para la construcción de dicha Reserva se realiza un diagnóstico que indica las principales características del Chuval, se identifican posibles riesgos para la conservación de sus valores ambientales, y se complementa el análisis con una propuesta de manejo que se enmarca en la metodología de Agendas Ambientales Locales desarrollada por la ONU. Pese a que el municipio es consciente de la relevancia ambiental del Chuval, aún no se han tomado decisiones definitivas para proteger esta zona, razón por la cual, la presente investigación busca llenar un vacío en el ordenamiento territorial del municipio, que fortalezca la protección de la Ciénaga Grande de Santa Marta.
