Advances in Power Electronics , 2012, DOI: 10.1155/2012/872383
Abstract: We present the bidirectional power line communication system developed in parallel to an electronic board for driving and control of HID (high-intensity discharge) and LED (light-emitting diode) lamps. The communication system, developed to be applied in the sector of public illumination, is been designed to combine high efficiency and reliability with low production costs; it consists indeed of discrete cheap components. The communication system described in this paper implements the technique of transporting digital information over existing power lines, avoiding the issue of installing new cables. Digitized signals can use power line cables through the amplitude voltage and current modulation. The solution proposed is more advantageous compared to communication techniques currently on the market which are essentially two types, power line carrier (modem for high-voltage lines) or radio (zig-Bee transceiver). 1. Introduction Public lighting represents a primary service in the management of a city. It is indeed public safety guarantor, helps to improve the environment in which people live, and promotes city image through the enhancement of cultural heritage. Geographical extension of public lighting system makes it very difficult in order to ensure proper levels of efficiency, quality, reliability, and energy savings of the service by using traditional instruments. An intelligent electronic system for the control of both LED and HPS lamps for public lighting was designed. The feature of driving both types of lamps is unique for the realized system. This versatility is achieved through the implementation of a reconfigurable output capable of driving, by the user’s choice, a LED or HPS lamp. Through an appropriate routine implemented in the firmware of the microcontroller, the system is capable of self-learning the type of lamp inserted in reconfigurable output. This feature allows to use the ballast in lighting systems that nowadays use the traditional discharge lamps and, primarily, will allow to keep the same ballast when discharge lamps will be replaced by the LED modules, in the near future in which the LED street lighting systems will be more affordable. The lighting implants are indeed characterized by a large number of hot spots scattered throughout the territory for which it is constantly necessary to monitor the operation and make its management. Particularly in urban areas, public lighting systems are greatly extended and widely distributed, and they contain a large number of control panels and, above all, light points. Therefore, it is

Abstract: Sa？etak Aim of this paper is to present a wireless monitoring smart system of household electrical facilities, with ZigBee/WiFi transceivers, able to detect absorbed current from electrical loads, to calculate dissipated power and energy by means of PIC-based software and to view, in real-time, calculated consumption values on web page properly realized for user’s remote control. Depending on light/presence sensors’ signal, the realized system can switch on/off the monitored electrical loads for obtaining energy saving and user satisfaction. Also by sending DALI-standard commands to slave loads (e.g lighting facilities based on LEDs), the user can monitor, remotely by using a tablet/smartphone connected to internet, the operation’s state and adjust the light intensity of each light point for achieving different scenarios. All functional tests, carried out on realized PCB prototype, have provided positive results allowing the use for the monitoring/driving of a real house’s electrical facilities

Abstract: Overweight and obesity are widespread chronic disorders defined as excessive fat accumulation, and are major risk factors for several chronic diseases including type 2 diabetes, coronary heart disease, high blood pressure and fatty liver. Changes in lifestyle such as increased physical activity and a healthy diet can be crucial tools for treating obesity. Intake of rose hip, the fruit of several plants belonging to the Rosaceae family, has been shown to reduce body fat mass and prevent body weight gain. Thus, the aim of the study was to elucidate potential mechanisms through which rose hip inhibit diet-induced obesity

Abstract: Multiple sclerosis (MS) has a relevant impact on quality of life (QOL) and is associated with increased risks of psychological morbidity. Mindfulness-based interventions (MBIs) are among the most studied interventions, although few well-conducted studies have tested them in this field. Furthermore, the participation in typical MBIs may be impaired by time and logistics. We aimed to test the efficacy of an online MBI to improve QOL, psychological well-being, sleep, and fatigue. We conducted a randomized controlled trial, in which 139 participants were randomly assigned to an MS-specific online mindfulness meditation intervention or to a psychoeducational (active control) group. Participants were assessed for QOL, depression, anxiety, sleep problems, and fatigue, at three different times: at recruitment, after 2？months, and after 6？months. In comparison to the control group, the experimental subjects reported higher QOL and lower depression, anxiety, and sleep problems at the end of intervention. However, after 6？months these group differences were no longer significant. An online MBI could be an effective psychological treatment for the promotion of well-being in MS in short-term. However, the lack of lasting effects requires the development of new strategies to support long-term changes

Abstract: Crenosoma vulpis (Dujardin, 1845), the fox lungworm, is a metastrongyloid affecting the respiratory tract of red foxes (Vulpes vulpes), dogs (Canis familiaris) and badgers (Meles meles) living in Europe and North America. The scant data available on the intermediate hosts of C. vulpis, as well as the limited information about the morphology of the larvae may jeopardise epidemiological studies on this parasite

Abstract: The ocular onchocercosis is caused by the zoonotic parasite Onchocerca lupi (Spirurida: Onchocercidae). A major hindrance to scientific progress is the absence of a reliable diagnostic test in affected individuals. Microscopic examination of skin snip sediments and the identification of adults embedded in ocular nodules are seldom performed and labour-intensive. A quantitative real-time PCR (qPCR) assay was herein standardized for the detection of O. lupi DNA and the results compared with microscopic examination and conventional PCR (cPCR). The specificity of qPCR and cPCR was assessed by processing the most common filarial nematodes infecting dogs, skin samples from O. lupi infected (n = 35 dogs) or uninfected animals (n = 21 dogs; n = 152 cats) and specimens of potential insect vector (n = 93 blackflies; n = 59 mosquitoes/midges). The analytical sensitivity of both assays was assessed using 10-fold serial dilutions of DNA from adult specimen and from a pool of microfilariae. The qPCR on skin samples revealed an analytical specificity of 100% and a sensitivity up to 8 x 10？1 fg/2μl O. lupi adult-DNA and up to 3.6 x 10？1 pg/2μl of mfs-DNA (corresponding to 1 x 10？2 mfs/2μl). Only 9.5% O. lupi-infected skin samples were positive for cPCR with a sensitivity of 8 x 10？1 pg/2μl of DNA. Out of 152 blackflies and mosquitoes/midges, eight specimens experimentally infected (n = 1 S. erythrocephalum; n = 1 S. ornatum; n = 6 Simulium sp.) were positive by qPCR. The qPCR assay herein standardized represents an important step forward in the diagnosis of zoonotic onchocercosis caused by O. lupi, especially for the detection and quantification of low number of mfs. This assay provides a fundamental contribution for the establishment of surveillance strategies aiming at assessing the presence of O. lupi in carnivores and in insect species acting as potential intermediate hosts. The O. lupi qPCR assay will enable disease progress monitoring as well as the diagnosis of apparently clinical healthy dogs and cats
