Authorities investigating a destructive Southern California wildfire set by an arsonist are asking for the public’s help in finding a truck seen in the area when the fire started. Authorities released a picture of a white Ford F-150 on Friday and say they want to talk to the driver. They are not calling the driver a suspect. Investigators say the vehicle was seen around the time the fire broke out in an Orange County canyon. The fire has burned 26,000 acres and destroyed 14 homes in the foothills east of Irvine.

Gifted musician Caoimhín Ó Raghallaigh is to travel the length and breadth of Irish traditional music at the Regional Cultural Centre this Saturday night.Dublin-born Ó Raghallaigh is to explore the beauty and humour of the music in ‘In My Mind – A Solo Fiddle & Film Show’ aided and abetted by his 10-string fiddle, a film projector and a host of virtual guests. He describes the fiddle as “a stunning 10-string instrument made by Norwegian luthier Salve Håkedal. The top five bowed gut strings plus the five sympathetic strings below give the fiddle a wonderful resonant sound.“It is somewhere between a hardanger fiddle and a viola d’amore. While Salve calls this instrument a 5+5, and Dan Trueman (for whom the first one was made) calls his a 5×5, I’ve decided mine likes being called a Hardanger d’Amore.”Ó Raghallaigh is both an established solo artist and a member of several acclaimed ensembles, including The Gloaming and This is How We Fly.He says his distinctive sound can be traced back to an early interest in uileann pipes and a love for the traditional music of Kerry and Clare. Ó Raghallaigh and Dán Trueman’s new album, Laghdú, recently went straight in at No.1 in the iTunes Ireland Charts for Traditional Folk.The virtual guests, whom he has filmed, include a musician, dancer, singer, poet and landscape, each of whom make the other half of a duet with a live Caoimhín.This is his journey showing the depth and beauty of traditional Irish music.In My Mind – A Solo Fiddle & Film Show at the Regional Cultural Centre, Letterkenny, Saturday, 8pm.A JOURNEY INTO THE HEART OF IRISH TRADITIONAL MUSIC WITH CAOIMHÍN Ó RAGHALLAIGH was last modified: October 7th, 2014 by John2Share this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window) Tags:Caoimhín Ó RaghallaighletterkennyRegional Cultural Centreviolin
In 2013, our old friends at Grantland released a 30-for-30 documentary on a little-remembered moment in the life of Muhammad Ali, who died on Friday at age 74. The film, made by Amani Martin and narrated by John Legend, recounts the story of Ali’s 1990 trip to Iraq before the Gulf War, during which he negotiated with Saddam Hussein for the release of American citizens taken hostage after the invasion of Kuwait. Ali risked his reputation, health and safety for the freedom of prisoners held by Hussein as “human shields” to deter U.S. military strikes. Only six weeks after Ali brought 15 hostages back home to their relieved families, Operation Desert Storm bombarded Iraq.
Local government, rural development and cooperatives minister Khandaker Mosharraf Hossain. UNB File Photo.Local government, rural development and cooperatives minister Khandaker Mosharraf Hossain on Friday said there is no alternative to vote for the ‘boat’ symbol.“The development of the country will be stopped if countrymen vote on any symbol other than boat,” the minister said, reports UNB.He said this while addressing a mass gathering at Government Rajendra College ground in Faridpur in the afternoon.The district unit of Bangladesh Awami League (AL) organised the gathering.The government led by prime minister Shiekh Hasina has been working to make the country hunger and poverty free as was dreamt by Bangabandhu Sheikh Mujibur Rahman, he added.
Final configuration of the robotic VFT with embedded trigger hairs and sensing signal integrated with a solid-state relay on board and a dynamic voltage signal generator to actuate the robotic VFT. Image: Bioinspir. Biomim. 6 046004. doi:10.1088/1748-3182/6/4/046004 At first glance, the creation of the robot might not seem like much more than a fun little project for an engineer who likes to tinker. On closer inspection however, it becomes clear that the robot Venus Flytrap is actually a demonstration of a new kind of technology that may lead to advances in medical applications. A refined application, for example, could perhaps one day lead to human muscle replacements or help with sensory applications. One example might be restoring facial expressions to people who lose the ability due to a stroke.Also, because Shahinpoor’s robot Flytrap has demonstrated an ability to catch flies it’s possible that such technology could also one day be used as a means for allowing robots to feed themselves, thus alleviating the need for a power supply. More information: Biomimetic robotic Venus flytrap (Dionaea muscipula Ellis) made with ionic polymer metal composites, Mohsen Shahinpoor, 2011 Bioinspir. Biomim. 6 046004. doi:10.1088/1748-3182/6/4/046004AbstractThe work described in this paper is a novel design of a robotic Venus flytrap (VFT) (Dionaea muscipula Ellis) by means of ionic polymeric metal composite (IPMC) artificial muscles as distributed nanosensors and nanoactuators. Rapid muscular movements in carnivorous plants, such as VFT, which are triggered by antenna-like sensors (trigger hair), present a golden key to study distributed biomolecular motors. Carnivorous plants, such as VFT, possess built-in intelligence (trigger hairs), as a strategy to capture prey, that can be turned on in a controlled manner. In the case of the VFT, the prey that is lured by the sweet nectar in the VFT pair of jaw-like lobes has to flip and move the trigger hairs, which are colorless, bristle-like and pointed. The dynamically moved trigger hairs then electro-elastically send an electric signal to the internal ions in the lobe to migrate outwardly for the jaw-like lobes to close rapidly to capture the prey. The manner in which the VFT lobes bend inward to capture the prey shows a remarkable similarity with typical IPMCs bending in an electric field. Furthermore, the mechano-electrical sensing characteristics of IPMCs also show a remarkable resemblance to mechano-electrical trigger hairs on the lobes of the VFT. The reader is referred to a number of papers in connection with sensing and actuation of IPMCs in particular. Thus, one can integrate IPMC lobes with a common electrode in the middle of one end of the lobes to act like a spine and use IPMC bristles as trigger finger to sense the intrusion of a fly or insect to send a sensing signal to a solid state relay which then triggers the actuation circuit of the IPMC lobes to rapidly bend toward each other and close. The two lobes, which form the trap, are attached to the midrib common electrode which is conveniently termed the spine. The upper surface of each lobe is dished, and spaced along the free margins of the lobes with some 15–20 prong-like teeth. These are tough and pointed, and are inclined at an inward angle so that when the trap is sprung shut they will interlock. We have been experimenting with the VFT closing of its jaw-like lobes that close in about 0.3 s and have gained a lot of knowledge to report on the ionic and electrical mechanisms involved in the operation of such intelligent distributed biomolecular motors.via Discovery To make the robot, Shahinpoor fashioned two “leaves” out of the material he’d created to mimic the mouth-like appearance of the Flytrap. He then created a spine from a roll of copper. Then to copy the tiny hairs on the Flytrap that function as the sensors, he added very small strips of the IMPC material. The rest of the robot was constructed as a normal relay and voltage generation system.The new material in the robot works in two ways. First, because of the unique properties of the IPMC material, simply touching it causes a very small voltage to be generated. The second is the muscle type flexing or bending, exhibited by the material when given a charge. With the robot, the small strips serve as sensors, that when touched, relay a tiny charge to the voltage generator which sends a little bit bigger charge to the “leaves” causing them to bend inwardly towards one another, or in viewing it, as a mouth closing on its prey.The material Shahinpoor invented bends when given a charge due to the redistribution of ions.

Biomim. 6 046004. doi:10.1088/1748-3182/6/4/046004 (PhysOrg.com) — Mohsen Shahinpoor, a professor of mechanical engineering at the University of Maine has created a robot version of the infamous bug eating Venus Flytrap, using a material he invented himself several years ago. Named ionic polymeric metal composite (IPMC), it’s a nanomaterial that can be used to mimic muscle function. Shahinpoor describes in his paper published in Bioinspiration & Biomimetics, how he used this material to recreate the sensing and closing abilities of the Venus Flytrap.
