The aim of the present study was to evaluate the influence of the Ramadan intermittent fast (RIF) on aerobic and anaerobic exercise performance in elite judo athletes (Judokas) maintaining their usual training loads. Physical performance tests (squat jump [SJ]), countermovement jump [CMJ], 30-second repeated jump, 30-m sprint, and the multistage fitness test) and fatigue scores were measured in...

Habitat use by the Little Blue Heron (Egretta caerulea) and discovery of feeding territoriality are discussed here. The results showed the existence of a territorial individual defending an area (2,564.46 +/- 943.56 m(2)) close to the mangrove, and non-territorial individuals (9.17 +/- 2.54) in the rest of a demarcated area (mean area for the non-territorial: 893.25 +/- 676.72). A weak positive...

The preparation of the first porphyrin-corrole dyad through click chemistry is described. The absorption, the emission and the electrochemical properties were investigated and suggested an efficient excited state interaction between the porphyrin and the corrole unit. Theoretical calculations were performed and proved that the dyad can potentially act as a molecular system for solar energy conv...

In everyday practice, geothermal energy is treated both by us professionals, and regular users as one of renewable energy sources. Although we tend to concentrate on its utility and technical value, geothermal is also part of our civilization and history. Therefore, it is worthwhile to spend some time investigating this kind of energy to learn its role and place in historical and cultural herit...

The pulsed electrical excitation of reactive metals like aluminum in water triggers a fast and highly energetic chemical reaction generating gaseous products. For applications such as fuses, safe explosives or fast gas generation, it is desirable to maximize the ratio of conductor mass to stored electrical energy while rapidly attaining a high resistive state. Various techniques have been used ...

Osteoporosis is the most common disorder of bone metabolism. The main consequence of this disease is the increased risk of fracture. Osteoporotic fractures represent a serious problem in terms of social and economic costs. Then, there is a strong need for the assessment of the best practices in prevention and treatment of osteoporosis. Dual X-ray absorptiometry (DXA) represents the current “gol...

We consider the NP-complete network connectivity problem of Dual Power Assignment (DPA). This models an ad hoc networks where each node can either operate at high or low power. The goal is to produce a minimum power strongly connected network. We give a Dual-Fitting algorithm to DPA with a 3/2-approximation ratio, improving the previous best know approximation of 11/7 ≈ 1.57. Another standard n...

Dual-energy (DE) CT scans provide two sets of measurements at two different source energies. In principle, two materials can be accurately decomposed from DECT measurements. For triple-material decomposition, a third constraint, such as volume or mass conservation, is required to solve three sets of unknowns from two sets of measurements. An image-domain (ID) method [1] has been proposed recent...
