Lymphomatoid papulosis is a unique paradoxic entity characterized by recurrent self-healing papulonodular lesions with histologic features of malignancy. Usually the disease has a protracted benign course; however, it can be associated with or evolve to a lymphoproliferative disorder. Thus "lymphoma-associated papulosis" represents the malignant end of a wide spectrum. We describe a case of a patient with lymphomatoid papulosis who developed Hodgkin's disease 8 years after the onset of skin lesions. ...

Built environment is increasingly dependent on the scientific knowledge which integrates urban design and climate. In the work presented here, the canyon thermal conductance which quantifies the heat transported outside of a canyon street, is analyzed to improve on understanding of how to accomplish this integration. A two-dimensional, steady, k–ε turbulence model is used to study the influence of a windward heated wall on the air flow circulation in a street canyon with building height-to-street ...

Urban planning has a considerable impact on the future energy efficiency of buildings and planners lack useful tools to support their decisions. This paper is intended to contribute to fill this gap by presenting a new method based on a genetic algorithm which is able to search for optimum urban forms in mid-latitude climates (35−50°). Here, more energy efficient urban forms are defined as those which have high building absorptance in winter and low summer building absorptance. These forms can be ...

Dengue fever is the most frequent arbovirus disease in the world and the most important one in terms of morbidity and mortality. Atypical manifestations of dengue have become commonplace during the last few years, including hepatic damage, which manifests mainly by pain in the right hypochondrium and an increase in the levels of aminotransferases. We describe a case of acute hepatitis in a patient with Dengue Shock Syndrome Grade III. We analyzed the clinical and laboratory aspects of this atypical ...

The development of city-driven urban laboratories was considered a priority by the European Commission through Action 3.2 of the Strategic Energy Technology Plan. In this context, positive-energy districts laboratories could take the role of urban drivers toward innovation and sustainability in cities. These urban labs can provide real-life facilities with innovative co-creation processes and, at the same time, provide testing, experimenting, and prototyping of innovative technologies. In this scope, ...

Building Integrated Photovoltaics (BIPV) are becoming an attractive solution in the context of high penetration of photovoltaics (PV) in buildings caused by the strive to achieve net or nearly zero energy status. Besides retrieving solar radiation to produce electricity, BIPV also offers aesthetical advantages because of its architectural feature. This paper reports on the electrical energy performance of a passive solar office building, Solar XXI, located in Lisbon, Portugal, which has installed ...

Today, cities allocate about 50% of world's population, and it is expected that this number will increase up to 80% in the upcoming years. The urban territory is responsible for a high percentage of natural resources consumption and waste generation, and therefore resource efficiency is critical to promote local and global sustainability. The characteristics of urban morphology and the growing trend toward urban transformation give cities enormous leverage in this respect. A Smart City could be ...

Based on an updated mathematical model, theoretical simulation has been conducted for BIPV-PCM in this case. Furthermore, field testing for this case has also been performed to validate the model, and then the simulated and experimental results are compared and found in considerably good agreement. The experiments have been conducted during the winter time, as the prototype ...

In this paper, cooling energy needs are calculated by the steady-state methodology of the Portuguese building thermal code. After the first period of building code implementation, re-evaluation according to EN ISO 13790 is recommended in order to compare results with the dynamic simulation results. From these analyses, a newly revised methodology arises including a few corrections in procedure. This iterative result is sufficiently accurate to calculate the building's cooling energy needs. Secondly, ...

Developing adsorbents from low‐cost and renewable resources is an attractive strategy. On the other hand, the high capacity of production rates of municipal solid waste, besides high methane emissions, is the origin of some eco‐systemic challenges. The combination of the two environmental problems is considered by introducing the compost from a mechanical biological ...
