This paper discusses the response of the United States lightning protection industry to a request for help from an orphanage in Haiti that addresses the educational and social needs of the poorest of the poor. The methodology used in this response can be applied to other applications to provide lightning-safe structures protected in accordance with national and/or international lightning protection standards. From the perspective of a developing nation, there is a benefit to working with non-profit organizations involved in lightning safety as they can provide the contacts necessary to properly assess the needs of the organization and implement the solutions required. © 2016 IEEE.

The 2nd edition of the lightning risk assessment standard (IEC 62305-2) considers structures which may endanger the environment. In these cases, the loss is not limited to the structure itself; which is the case for 'usual' structures. In Edition 1 of the standard this danger was simply taken into account by multiplying the calculated risk for the structure by a special hazard factor. In Edition 2, the calculated risk for the structure itself is added to another risk associated with the losses outside of the structure. The losses outside can be treated independently from what occurs inside. This is a major advantage in the analysis of the risk for sensitive structures such as chemical plants, nuclear plants, or structures containing explosives, etc. Edition 3 of the standard is currently under preparation. It is important to better define what the environmental risk really is and how it can be calculated efficiently. A methodology proposed in previous publications has been adapted to real cases already studied with Edition 1 of IEC 62305-2 for comparison. © 2015 IEEE.

The colonisation of activated zeolites (i.e. clinoptilolites) as carriers for microorganisms involved in the biogas process was investigated. Zeolite particle sizes of 1.0-2.5. mm were introduced to anaerobic laboratory batch-cultures and to continuously operated bioreactors during biogas production from grass silage. Incubation over 5-84. days led to the colonisation of zeolite surfaces in small batch-cultures (500. ml) and even in larger scaled and flow-through disturbed bioreactors (28. l). Morphological insights were obtained by using scanning electron microscopy (SEM). Single strand conformation polymorphism (SSCP) analysis based on amplification of bacterial and archaeal 16S rRNA fragments demonstrated structurally distinct populations preferring zeolite as operational environment. via sequence analysis conspicuous bands from SSCP patterns were identified. Populations immobilised on zeolite (e.g. Ruminofilibacter xylanolyticum) showed pronounced hydrolytic enzyme activity (xylanase) shortly after re-incubation in sterilised sludge on model substrate. In addition, the presence of methanogenic archaea on zeolite particles was demonstrated. © 2010 Elsevier Ltd.

Rescuers walk among the debris of collapsed buildings as excavators and trucks work at the site of a landslide which hit an industrial park on Sunday, in Shenzhen, Guangdong province, China, December 23, 2015. Two people died and more than 70 people were missing after Sunday's landslide at an industrial park in Shenzhen, a boomtown near Hong Kong, in China's latest industrial disaster. A man was pulled out alive from the rubble on Wednesday. The man-made disaster has raised questions about China's industrial safety standards and lack of oversight. On Tuesday, police raided offices of Shenzhen Yixianglong, the company managing the dump site. Executives from the Shenzhen J-star Project Management Consultant Co., a consulting company which was hired by officials in Shenzhen to supervise engineering projects, had first recommended that Yixianglong "stop all work" and repeatedly requested that they do so in the next few months, Bian Yuxiang, J-star's deputy general manager, told Reuters by telephone. Bian said that J-star highlighted five issues about the dump site to government investigators, questioning quality inspection and saying Yixianglong had failed to carry out tests on slopes around the area and did not meet safety standards such as the wearing of helmets. In a Dec. 16 meeting that was attended by officials from the Guangming New District Urban Management Bureau and the Shenzhen Keyu Engineering Consultant Co. Ltd, an engineering consulting firm, J-star urged Yixianglong to suspend all operations, Bian said. "All the parties present agreed to it," Bian said, adding that the work should have stopped then. Bian said J-star "did not have the right" to order Yixianglong to stop the work. "My responsibility is to report the problems I've discovered to the Guangming Urban Management Bureau. It is up to the urban management bureau to execute the order," he said. Calls to Yixianglong, the Guangming New District Urban Management bureau and the Shenzhen Keyu Engineering Consultant Co. went unanswered. State news agency Xinhua said previously that the dump was being used 10 months after it was supposed to have stopped taking waste, earning Yixianglong some 7.5 million yuan ($1.16 million) in fees.

The solar chimney is a passive cooling technique to enhance the natural ventilation of buildings. The effect is, however, limited under hot and humid climatic conditions. In the study, the solar chimney was accompanied by a dew-point evaporative cooler. The dew-point evaporative cooler was integrated with the ceiling of a building. The air flow induced by the solar chimney was predicted by simulation, and the cooling effect of the dew-point evaporative cooler was also analyzed by heat and mass transfer simulation. The results showed that the system was capable of coping with internal heat gains of an ordinary office building. In addition, the optimal geometry of the evaporative cooling channel was revealed. © 2011 Elsevier B.V. All rights reserved.

A novel and memory efficient method for computing diffraction patterns produced on large-scale focal planes by largescale Coded Apertures at wavelengths where diffraction effects are significant has been developed and tested. The scheme, readily implementable on portable computers, overcomes the memory limitations of present state-of-the-art simulation codes such as Zemax. The method consists of first calculating a set of reference complex field (amplitude and phase) patterns on the focal plane produced by a single (reference) central hole, extending to twice the focal plane array size, with one such pattern for each Line-of-Sight (LOS) direction and wavelength in the scene, and with the pattern amplitude corresponding to the square-root of the spectral irradiance from each such LOS direction in the scene at selected wavelengths. Next the set of reference patterns is transformed to generate pattern sets for other holes. The transformation consists of a translational pattern shift corresponding to each hole's position offset and an electrical phase shift corresponding to each hole's position offset and incoming radiance's direction and wavelength. The set of complex patterns for each direction and wavelength is then summed coherently and squared for each detector to yield a set of power patterns unique for each direction and wavelength. Finally the set of power patterns is summed to produce the full waveband diffraction pattern from the scene. With this tool researchers can now efficiently simulate diffraction patterns produced from scenes by large-scale Coded Apertures onto large-scale focal plane arrays to support the development and optimization of coded aperture masks and image reconstruction algorithms. © 2012 SPIE.

Lightning can pose a myriad of threats to operations involving flammable vapors and liquids that give off flammable vapors. This paper focuses primarily on storage facilities and associated operations but the principles can be applied to any operation or installation where a flammable environment may exist. General principles of protection from a lightning threat are provided, along with a discussion of specific threats presented by operations in which flammable vapors may be present. The evolution of protection considerations is also discussed. Techniques for protection from direct attachment are provided to address those situations where an external flammable vapor could exist in the vicinity of a storage vessel. Threats produced by nearby lightning and strikes to associated piping and electrical conduits are also addressed. The elimination of both external and internal potential differences that could lead to dangerous arcing is discussed. This paper also provides a discussion of the difference in grounding system impedance versus static grounding techniques as they relate to the dissipation of lightning currents and explains their significance in minimizing the probability of arcing between structural components and systems. The principles discussed are summarized in the context of the development of a lightning protection plan.

The aim of the present work is the construction of a nonlinear dynamic model of lung/airway mechanics using generic instead of specific software, in an attempt to offer an open simulation environment. Based on the analogy between pneumatic and electric magnitudes, an electrical equivalent circuit of the lung/airway mechanics is derived. Then, the nonlinear circuit elements are constructed by means of the powerful Analog Behavioral Modeling (ABM) building blocks and the system is solved using PSPICE. Five lumps are defined: two capacitors (elastances) corresponding to lung and collapsible airway segment and three resistors, corresponding to lung, collapsible airway segment and upper airway. The model does not attempt to mimic any particular system by adjusting a given set of parameters but instead to provide a tool to explore the relationship between a given parameter or set of parameters and the system response, in particular for the Forced Vital Capacity (FVC) maneuver.

The purpose of this paper is to discuss the recent developments in multi-axial spectral methods, used for estimating fatigue damage of multi-axial random loadings from Power Spectral Density (PSD) data. The difference between time domain and frequency domain approaches in multi-axial fatigue is first addressed, the main advantages of frequency domain approach being pointed out. The paper then critically reviews some categories of multi-axial spectral methods: approaches based on uniaxial equivalent stress (strength criteria, “equivalent von Mises stress”, multi-axial rainflow counting), critical plane criteria (Matake, Carpinteri-Spagnoli, criterion based on resolved shear stress on critical plane), stress-invariants based criteria (Crossland, Sines, “Projection-by-Projection”). The “maximum variance” method and the Minimum Circumscribed Circle/Ellipse formulations defined in the frequency domain are also discussed. The paper critically analyses also non-proportional multi-axial loadings and the role of material fatigue parameters (e.g. S/N curves for bending/torsion) in relation to specific methods. The paper concludes with general comments on advantages and possible limitations in the use of multi-axial spectral methods, with special focus on the assumption of stationarity and Gaussianity in modelling multi-axial random loadings. © 2016 Elsevier Ltd
