Communication System For Firefighters

Currently firefighters use two-way radios to communicate on the job, and they are forced to write reports based on their memory because there is not an easy way to record the communications between two-way radios. Firefighters need a system to automatically document what happened while they were responding to a call. To save them a significant amount of time when creating reports, our solution is to implement an application that allows firefighters to take pictures, record video and communicate in real time with their team of on-site responders. The proposed system will use a Wireless Local Area Network (WLAN) hosted on the fire truck itself to act as an access point (AP) to which the firefighters can connect. This AP will also save communication between firefighters to a local storage location. Upon return to the fire station, the AP will route all of the information stored locally to a larger database. For now, Wi-Fi will be our communication medium, with a prediction that our technology can eventually be extended to include radio signal

Pengaruh Lama Waktu Fermentasi terhadap Kadar Bioetanol dari Pati Ubi Jalar Kuning (Ipomea Batata L)

The sweet potato is yellow is one that the carbohydrate that is high, so it can be used as one of the alternative raw materials for bioethanol. This study aims to determine the levels of ethanol sweet potato is yellow through fermentation with the use of yeast bread with a variety of time 3, 4, 5, 6, dan 7 days at room temperature. The results of the research showed glucose levels derived from the process of hydrolysis using acid HCl 21% were of 4.54% with high levels ethanol that optimum obtained through fermentation use of yeast Saccharomyces cerevisiae of 9.70% over fermentation 5 days

Zur Archäologie und Landschaftsentwicklung im Turano-Tal (Sabiner Berge), Italien

Ein archäologisch-geographisches Kooperationsprojekt im Turano-Tal, nordöstlich von Rom, untersuchte die Landschafts- und Besiedlungsgeschichte. Die mächtigen Talverfüllungen des Untersuchungsgebietes, die in den letzten 5500 Jahren gebildet wurden, dokumentieren die Verzahnung von kolluvialen und fluvialen Sedimenten. Um 2200 BC zeigt sich eine deutliche Veränderung der fluvialen Systeme mit einer stetigen Zunahme der Sedimentmächtigkeiten. Die kumulierten 14C-Datierungen zeigen Intervalle verstärkter Sedimentverlagerung, die die historische Landnutzung sowie soziale Umbrüche widerspiegeln. Der archäologische Fokus der Untersuchung lag auf Zeugnissen der römischen Besiedlung. In diesem Zusammenhang ist ein römischer Tempel besonders bedeutungsvoll, der unter der Kirche auf dem Berg San Giovanni liegt und eine Zentralortfunktion auf das umgebende Tal ausübte. Zudem wurde eine Dokumentation zu einer bereits bekannten monumentalen Grabinschrift durchgeführt. Zentral-Apennin; Alt-Sabiner Land; Spät-Holozän; Landschaftsentwicklung; Besiedlungsgeschichte; Historische Landnutzung; Römische Besiedlung. A joint project of archaeologists and geographers investigated the landscape development and settlement history of the Turano valley, NE of Rome. The valley fills in the area were deposited during the last 5500 years and show an interlocking of colluvial and fluvial sediments. From c. 2200 BC onwards a continuous increase in sediment thickness attests to modifications of the fluvial systems. The distribution of C-dates exhibits intervals of intense sediment dislocation representing changes in land use and society. Archaeological research focused on evidence of Roman settlement activities. In this context a Roman temple situated in the basement of the medieval church on Mount San Giovanni is of particular interest, as it served the surrounding valley as a central place. Additionally, an already known monumental grave inscription was documented

Pressure Kicks: The Effects of Distracting Variables on the Outcome of a Pressure Kick in Division-I College Football

A field goal kicker in NCAA Division-I college football experiences high amounts of pressure when placed in a game-winning situation. A pressure kick may result in optimal or less than optimal performance due the influence of various distracting factors, such as the evaluative nature of an audience or the pressure of being iced by the opposing team. Pressure kicks are classified as a field goal kick, during the last minute of game time (or during overtime), which will result in a lead or a tie game for the kicking team (Goldschmied, Nankin, & Cafri, 2010). Conflicting literature surrounding social facilitation, home field advantage, pressure, and uncertainty have determined that an elite athlete in a high-pressure game-winning situation will either perform at an optimal or less than optimal level based on their level of mastery in the particular skill. In addition, the effects of various distracting variables may also influence their performance positively or negatively. The purpose of this study is to determine which distracting variables have an effect on the outcome of a pressure kick in Division-I college football. Archival data was collected from ESPN college football scoreboard for NCAA FBS games played during seven consecutive football seasons (2006- 2012). In the seven seasons, 358 pressure kicks occurred, but only 324 cases were applicable due to missing data. The overall team performance and the individual kicker\u27s ability to kick from a field goal distance were found to be the strongest predictors for the success of a pressure kick. Given these two measures, the data set predicted the kicker will successfully make the pressure kick attempt 9 out of 10 times, with or without being iced

Simple circuit provides adjustable voltage with linear temperature variation

A bridge circuit giving an adjustable output voltage that varies linearly with temperature is formed with temperature compensating diodes in one leg. A resistor voltage divider adjusts to temperature range across the bridge. The circuit is satisfactory over the temperature range of minus 20 degrees centigrade to plus 80 degrees centigrade

PI3K-C2 alpha Knockdown Results in Rerouting of Insulin Signaling and Pancreatic Beta Cell Proliferation

Insulin resistance is a syndrome that affects multiple insulin target tissues, each having different biological functions regulated by insulin. A remaining question is to mechanistically explain how an insulin target cell/tissue can be insulin resistant in one biological function and insulin sensitive in another at the same time. Here, we provide evidence that in pancreatic beta cells, knockdown of PI3K-C2 alpha expression results in rerouting of the insulin signal from insulin receptor (IR)-B/PI3K-C2 alpha/PKB-mediated metabolic signaling to IR-B/Shc/ERK-mediated mitogenic signaling, which allows the beta cell to switch from a highly glucose-responsive, differentiated state to a proliferative state. Our data suggest the existence of IR-cascade-selective insulin resistance, which allows rerouting of the insulin signal within the same target cell. Hence, factors involved in the rerouting of the insulin signal represent tentative therapeutic targets in the treatment of insulin resistance.11108Ysciescopu
