Emme Hall/Roadshow When Ford announced that it was going to put a brand-new diesel engine in its F-150 line in its F-150 line, we were excited, as probably were most of you. We got less excited when we found out that this torque-monster of an engine, ideal for doing real work, would only be available in the top Lariat, King Ranch and Platinum trim models.Ford, however, didn’t get to be one of the biggest car companies on Earth by being a bunch of dummies, so it decided to take customer criticism to heart and announced on Thursday that it would add the PowerStroke diesel to the list of available engines on the best-selling XLT trim F-150.”Customers and dealers told us they wanted the diesel on XLT, so we decided to expand the offering,” Dawn McKenzie, truck communications manager for Ford, told Roadshow. “Now, the 3.0-liter Power Stroke diesel will be available on 75% of our offerings, including XLT, which is our most popular series.”What does that mean from a real-dollars standpoint? Well, the base XLT starts at $34,160 while the Lariat trim, before options, goes for $41,700. The King Ranch goes for over $52,000. So it’s a massive reduction in price for someone to get into an F-150 diesel. If you want one, order books are open now. Trucks Diesel Cars Ford Tags

DOI: 10.1063/1.4866440 Using graphite pencils to draw on regular paper, researchers can make some very inexpensive piezoresistive (PZR) sensors. Due to the piezoresistive effect, a sensor’s resistance changes under an applied strain, allowing it to sense mechanical stress and pressure. The first of these pencil-on-paper PZR sensors was fabricated a few years ago as an alternative to silicon PZR sensors, which are costly and require sophisticated fabrication processes.

Credit: Kang ©2014 AIP Publishing Journal information: Applied Physics Letters “PZR sensors can be drawn by anyone with a graphite pencil and paper,” Ting-Kuo Kang, a researcher at Cheng Shiu University in Kaohsiung City, Taiwan, told Phys.org. Although graphite PZR sensors are much easier to fabricate than silicon ones, they generally are not as sensitive because graphite’s electrical properties are not as good as those of silicon. In a new study published in Applied Physics Letters, Kang has further investigated the underlying mechanisms of graphite’s PZR properties and improved the sensitivity of graphite-based PZR sensors.PZR sensitivity is characterized by the gauge factor (GF), which is defined as the ratio of the change in electrical resistance to the applied strain. While silicon PZR sensors have GFs above 100, the GFs of graphite PZR sensors are in the single digits.In experiments, Kang used 12 different grades of graphite pencils to draw U-shaped PZR sensors on paper. The pencils are graded by their ratio of graphite to clay. Grades ranged from 9B to 2H, where H denotes the hardness caused by the pencil’s clay content, and B denotes the blackness due to the graphite content. The sensors were drawn on paper that was placed on an electric scale in order to measure and maintain a consistent drawing force for each pencil-drawn sensor. The drawings were then glued on printed circuit board (PCB) strips, and a strain gauge mounted on each PCB strip. Then Kang applied cycles of stress to the sensor using a four-point bending technique, and measured the sensor’s voltage change under the applied stress through an electric circuit. He found that different pencil grades produce different GF values, and therefore different PZR sensitivities. Specifically, the higher the ratio of clay to graphite, the greater the change in resistance under the applied stress, and the greater the GF. Kang explains that these differences can be attributed to variations in the initial tunneling distances between neighboring graphite, with an increase in tunneling distance corresponding to an increase in GF.”The graphite tunneling effect is from one graphite through the insulator of clay to another graphite,” Kang said. “The tunneling structure looks like a metal-insulator-metal.”Currently, PZR sensors made of silicon are used as pressure sensors, accelerometers, and biological sensors, among other applications. As the sensitivity of pencil-drawn graphite PZR sensors continues to improve, they may also be used for these applications. Kang also plans to develop flexible and disposable sensor applications using pencil-on-paper techniques.

Cinnamon just not enhances taste but significantly contributes in improving health by cooling the body by up to two degrees, according to research. The research published in the journal Scientific Reports said that the investigators used pigs for the study and found that cinnamon maintained the integrity of the stomach wall.“When pigs feed at room temperature, carbon dioxide (CO2) gas increases in their stomach. Cinnamon in their food reduces this gas by decreasing the secretion of gastric acid and pepsin from the stomach walls, which in turn cools the pigs’ stomachs during digestion,” said Kourosh Kalantar-zadeh, Professor at the RMIT’s School of Engineering.

They are a highly reliable device for monitoring and diagnosing gastrointestinal disorders,” Kalantar-zadeh added.
Here is a great news for bibliophiles as an end of this January will bring in the 42nd edition of Kolkata International Book Fair. A 10 member French literary delegation, headed by French cultural Minister Francoise Nyssem, will be attending the fair. The announcement was made by French ambassador Alexandre Zeigler, during a press conference held at Press Club of India. The fair, which is one of the largest around the world, will commence on January 31 and will last till February 11, at the Salt Lake Central Park.

Also, Tridib Kumar Chatterjee, General Secretary of the book fair said that it’s the first time they had organised joint sessions of noted writers, intellectual of West Bengal and of other parts of the country along with the visiting French literary delegation.Kolkata Book fair is recognised by International Publisher Association of Geneva. Chatterjee stated that last year 22 lacs people attended the fair. But organisers are expecting more book lovers to attend the fair this time. For this state government has made elaborate arrangement for transportation. More than 175 special bus service will be running from different corners of the city.

The fair will be inaugurated by the eminent French author Leonora Miano along with the chief minister of West Bengal, in presence of the French minister, on January 30 at 5-30 pm. The closing ceremony will be of Bonjour India festival which is unique in nature. The 5th edition of Kolkata Literature festival –an integral part of the International book fair – will be held at the auditorium of the fair ground for three days, starting from February 10. Many writers from abroad will participate in this festival as told by the Director of the KLF Sujata Sen. As in the previous years, a lucky draw will be held during throughout and the winners will get gift vouchers to purchase books. The grand finale will be organised on the last day of the Fair and the winner will get a new car. The main roads of the book fair will be named after legends of France in celebration of the 70th year of Indo-French relationship. Celebration of the 70th year of Indo-French relationship.
