One of the least used aspects of BIM (Building Information Modeling) is the ability to obtain the building’s energy model using the BIM methodology known as BIM 6D. This digital information model allows to simulate the real energy behavior of the building and improve the lighting systems of the building. In this way, the BIM 6D simulation allows us to make design and operational decisions for the building, not only for new buildings that must be NZEB (Nearly Zero Energy Building) according to current legislation, but also for the rehabilitation of existing buildings. BIM 6D allows an exhaustive analysis of the energy effects of this rehabilitation, especially in the case of sanitary buildings, and brings with it an energy and lighting improvement, which in turn leads to greater quality and comfort in the sustainable use of the building. This issue takes on special relevance in public buildings, where energy efficiency and comfort, aimed at optimal and efficient lighting, are two fundamental criteria highly valued by patients and the public. Once the building’s energy model has been prepared, it will be possible to study and identify possible alternatives to improve energy efficiency and lighting, as well as analyze the possibilities of incorporating other more efficient forms of renewable energy such as the use of natural light. In this work we can see how, applying a series of improvement measures simulated in BIM 6D, an energy saving of 50% is achieved in general and of up to 13% only by acting on lighting systems, which allows the energy decarbonisation of buildings high consumption. as hospitals and will improve the energy certification of these buildings; As a result, a better and higher quality of life is achieved through the use of more efficient forms of lighting and the conversion of buildings into more sustainable spaces.

The source tracking of fungal contamination in the food industry is an important aspect of food safety. Currently, all available methods are time consuming and require the use of a reference library that may limit the accuracy of the identification. In this study, we report for the first time, a library-independent FTIR spectroscopic approach for MST of fungal contamination along the food production line. It combines high-throughput microcultivation and FTIR spectroscopy and is specific on the genus and species level. Therefore, such an approach possesses great importance for food safety control in food industry.

We focus in this paper on the performance evaluation of video streaming over mobile ad-hoc networks (MANETs) us- ing resource constrained handheld real world devices, namely Nokia 770/N800 Internet Tablets. The main results from our experiments reveal that in principle video streaming in a multi-hop wireless ad-hoc network using such devices is pos- sible. However, playing and forwarding the video stream at the same time could become infeasible, as receiving and play- ing a high-quality video stream at 1Mbps consumes almost 100% of the CPU time. In addition, an intermediate for- warding node is a potential bottleneck, being able to handle only three simultaneous high-quality (1Mbps) video streams before the CPU becomes overloaded. Our results emphasize the importance of resource monitoring and optimization for any future video streaming solutions for resource constrained devices in such networking environments.

To determine the recovery of Bacillus subtilis spores loaded onto preformed cartons and irradiated with u.v.-excimer laser (248 nm) light. Bacillus subtilis spores irradiated with u.v.-excimer laser light retained phase brightness, but were blocked at various stages of germination. In the presence of germinant, the majority of spores began to lose phase brightness but only after an extended lag period (ca 90 min). After 6 h ca 9% of the spores had elongated but failed to form new cells, approx. 12% had undergone partial phase darkening (grey spores), 15% remained phase bright whilst the remainder had turned fully phase dark but failed to elongate. No enhanced recovery of u.v.-treated spores (with intact or permeabilized coats) occurred in media containing hen egg white lysozyme or vegetable extracts (celery, carrot, swede or turnip). However, recovery did occur when irradiated spores were incubated for 26 d, semiaerobically, within cartons containing nutrient broth or milk. The germination ability of B. subtilis spores is altered following u.v.-excimer laser treatment. Recovery of treated spores was found in liquid systems but not on agar plates supplemented with vegetable extracts or lysozyme. The potential recovery of u.v.-excimer laser-treated spores in a range of carton-packed food systems requires further investigation.
