Covert communications between underwater and aerial platforms would increase the flexibility of surface and air vehicles engaged in undersea warfare by providing a new netcentric warfare communication capability and could have a variety of commercial and oceanographic applications. Research into an acousto-optic sensor shows promise as a means for detecting acoustic data projected towards the w...

9 Low enthalpy geothermal energy is a renewable resource that is still underexploited nowadays, in 10 relation to its potential for development in the society worldwide. Most of its applications have 11 already been investigated, such as: heating and cooling of private and public buildings, roads defrost, 12 cooling of industrial processes, food drying systems or desalination. 13 Geothermal pow...

If Nature is supersymmetric at the weak interaction scale, what can we hope to learn from experiments on supersymmetric particles? The most mysterious aspect of phenomenological supersymmetry is the mechanism of spontaneous supersymmetry breaking. This mechanism ties the observable pattern of supersymmetric particle masses to aspects of the underlying unified theory at very small distance scale...

Two tragic tsunamis that devastated the west coast of Sumatra Island, Indonesia in 2004 and North East Japan in 2011 had damaged bridges to various extents. Tsunamis have resulted in the catastrophic deterioration of infrastructures i.e. coastal structures, utilities and transportation facilities. A bridge structure performs vital roles to enable people to perform activities related to their da...

BACKGROUND Occurrence of psoriasis has been found to be strongly genetically controlled in Northern European and U.S. twin and family studies. OBJECTIVE Our purpose was to assess cumulative incidence and heritability of psoriasis in the Australian population. METHODS Australian twins reporting psoriasis on a screening questionnaire received from 3808 pairs were mailed a detailed instrument ...

While multiple studies have shown that a woman’s control over land is positively associated with bargaining power outcomes, few have succeeded in highlighting successful methods for increasing this control. We report on a policy experiment in an unplanned settlement in Dar es Salaam, Tanzania, that provided access to formal land titles to informal settlers at randomized prices, with additional ...

OBJECTIVES To assess whether public health nurses adhered to Dutch guidelines for tuberculosis contact investigations and to explore which factors influenced the process of identifying contacts, prioritizing contacts for testing and scaling up a contact investigation. METHODS A multiple-case study (2010-2012) compared the contact investigation guidelines as recommended with their use in pract...

OBJECTIVE Area 7 of the autonomous region of Madrid has one of the highest incidences of tuberculosis (23/100,000 population per year 2004). This study aimed to identify tuberculosis control in this area. METHODS A descriptive study of tuberculosis cases diagnosed in area 7 from January 1, 1999 to December 31, 2004 was carried out by analyzing the incidence of tuberculosis and the management ...
