Vendors Roll Out New Centrino Notebooks Citation: Fujitsu’s ‘Laptop4Life’ program gives you a new laptop every 3 years (2008, December 1) retrieved 18 August 2019 from ( — Buy any LifeBook laptop from Fujitsu Siemens, and the company will provide you with a new laptop every three years until you die. The only requirements are that you need to buy a three-year extended warranty, you can only upgrade using Fujitsu parts, and you must turn in your laptop in good condition with the original receipt after three years. As part of the scheme, Fujitsu will give LifeBook customers a new laptop of the same value as the one they originally bought, plus 10% to cover inflation. Most importantly, the new laptop will be equipped with updated hardware and software. To participate, customers must register their new laptop within 21 days of purchase. Then, customers are part of the program for life, but they cannot pass on the deal in a will. Fujitsu is also limiting purchases to 10 laptops per person or business. Although it seems like the company is giving away laptops, Fujitsu says that it will make money by selling other goods, services, and accessories to its lifetime customers. For instance, customers may want to invest in a Fujitsu insurance pack to protect their laptop against theft and accidental damage. Fujitsu says that the Laptop4Life program underscores its high level of confidence in its technology.More information: Fujitsu Siemensvia: ITPro and Oh Gizmo!

Disneys magical vision calls for 3D printed optical elements w Video

first_imgLight pipes are 3-D printed optical elements that are similar but not identical to optical fiber. They can be used to guide light from point to point. The paper explained that “Unlike conventional optical fiber, 3-D printed light pipes allow arbitrary geometries to be created in software and then locations on the surface of a mobile device to a single sensor array.” They add that light pipes can be printed into the walls of a device to create robust and exceptionally thin, sub mm, embedded sensing with minimal hardware assembly.As for when all this will be possible, the authors are optimistic about possibilities for fabricating light pipes in the next generation of optically optimized 3D printers.

Printed Optics: 3D Printing of Embedded Optical Elements for Interactive Devices. In Proc. ACM UIST (2012). Paper [PDF, 1.5MB] © 2012 “We envision future interactive devices that are not assembled but 3-D printed layer by layer,” the authors said. They talk about how novel elements can be fabricated with 3-D printing and embedded in interactive devices. They talk about new possibilities in display surfaces and embedded optoelectronics. They see “tremendous potential” for rapid high fidelity prototyping, and eventually for production of customized devices tailored to specific tasks. They said that the ability to dynamically control optical properties such as the refractive index, reflectivity, transmittance, absorption, and diffusion will enable a richer design space for sensing, display, and illumination. “Although that time is not upon us yet, Printed Optics demonstrates what is possible today.” They define Printed Optics as a new approach to creating custom optical elements for interactive devices using 3-D printing.

Researchers remove oil from water using copper cones inspired by cactus spines

However, for most existing separation methods, phase separation occurs in the oil–water mixture. The remaining micron-scale oil droplets, which are not affected by phase separation, are difficult to handle with conventional methods on a large scale because of either a lack of separation ability or drawbacks in throughput capacity. Here we develop an oleophilic array of conical needle structures for the collection of micron-sized oil droplets, inspired by the collection of similar sized water droplets on conical cactus spines. Underwater, these structures mimic cacti and can capture micron-sized oil droplets and continuously transport them towards the base of the conical needles. Materials with this structure show obvious advantages in micron-sized oil collection with high continuity and high throughput.

In their paper published in the journal Nature Communications, the team describes how an array of their cones could be used to help clean up oil spills. Cactus plants have evolved a unique way to pull water out of the air—they have conic spines that jut out allowing water condensation to build up on them. But, because of the unique shape of the spines, the water surface tension causes the water droplets to be pulled towards the base of the spine where they are absorbed by pores in the plant. This process allows cactus plants to survive in extremely arid places. In this new effort, the researchers in China have created artificial spines out of copper and other synthetic materials that perform essentially the same function, only they pull oil along their conic form, while immersed in water.The idea is based on prior research that has shown that when oil is spilled into the ocean, some of it floats on the surface, while some of it does not. Instead, it reacts with seawater and forms microscopic droplets of water that are too heavy to float. They wind up either suspended in the water, or falling to the ocean floor. To capture these tiny droplets, the team in China affixed multiple copper spines to a central structure—each (0.5 millimeter length) spine pulls oil out of the water whic travels along its length at a rate of 2 millimeters per second—creating a device that is capable of cleaning up the oil from spills that is typically missed during cleanup operations.

To create oil-spill like conditions, they added oil to water than caused the formation of microscopic droplets by blasting it with ultrasonic sound waves. Tests run thus far have found the device capable of extracting up to 99 percent of the oil mixed into water and that the device works with virtually any type of oil. © 2013 Discovery could lead to new way of cleaning up oil spills This document is subject to copyright.

Why a rat eradication attempt on Henderson Island failed

first_img(—A team of researchers the University of Cambridge and the Royal Society for the Protection of Birds has conducted a case study of a failed rat eradication project on an island in the South Pacific. In their paper published in Royal Society Open Science, the team reports that it has found that the failure was not due to migration of new rats to the island, or some of the rats being able to withstand the poison used, but instead because some of the rats never ate the poison and then began reproducing at a rapid pace. Explore further Approximately 800 years ago Polynesian sailors introduced Pacific rats to Henderson Island, where they rapidly multiplied. Today there are no people living on the islands but lots of rats, which is a problem, because they eat the chicks of endangered birds. For that reason, a team with the Royal Society for the Protection of Birds and the government of the Pitcairn Islands decided to solve the problem by killing every rat on the island. A study was conducted and in 2011, a helicopter flew over the island and dropped seventy-five metric tons of rat poison at pre-chosen locations—a strategy that had been used successfully on other islands in the South Pacific. Unfortunately, this effort did not prove successful. Today the rat population is back to where it was before the eradication effort was made—approximately 100,000.In their case study, the researchers conducted DNA tests to make sure the rats that are there now are not descendents of rats from somewhere else—they were not which ruled out migration of new rats as the problem. The team also ran multiple tests and determined that it was not possible that some of the rats could have survived after eating the rat poison. That left only one possible reason for the failure—some of the rats had not eaten the rat poison, and thus were not killed. After careful analysis, the team suggests that approximately 50 rats likely survived the rat drop and that it was likely due to an unexpected rainfall that had occurred just prior to the rat poison dump—fruit and flowers were plentiful which made the rat poison less of an attractive option. The large number of rats today is the result of the rapid pace of reproduction of the rats—one female bears up to six pups every few months. The Royal Society is not ready to give up however, they plan to try again, but next time around will plan their attack around the weather. © 2016 Credit: Michael Palmer/Wikipedia/CC BY-SA 4.0 Citation: Why a rat eradication attempt on Henderson Island failed (2016, April 20) retrieved 18 August 2019 from read more

The man who immortalised Nira

A doyen of Bengali literature, Sunil Gangopadhyay called poetry his first love, but successfully delved into all literary genres with his versatility and varied experiences of life, leaving generations of readers in India and Bangladesh mesmerised over decades with his creativity and writing style.Often a bohemian in lifestyle, Gangopadhyay was one of the most popular poets in post-Rabindranath Tagore Bengal, with his Nira series of poems having retained their popularity, particularly among the youth, through the years. Also Read – ‘Playing Jojo was emotionally exhausting’A prolific writer, Gangopadhyay authored more than 200 books over six decades, with his magnificent range of creations touching upon diverse segments like novels, children’s fiction, poetry, literary criticism, travelogue and essays.Gangopadhyay was born in Faridpur, now in Bangladesh, in 1934, and his family shifted before the partition to Kolkata – a city that saw the flowering of his talent shaped by a passion for reading and endless informal chat sessions with literary and other cultural geniuses and even the ordinary people from all walks of life. Also Read – Leslie doing new comedy special with NetflixHowever, it was Gangopadhyay’s father – a teacher – who played a catalytic role in bringing out his poetic talent.‘After my school final examination, my father – to keep me engaged – asked me to translate Tennyson. After translating some of the poems, I thought why don’t I try out my hand in writing some poems of my own? I liked what I wrote.’ His first poem Ekti Chithi [A letter] was published in 1950.In the 1950s, Gangopadhyay and some of his friends brought out a seminal poetry magazine Krittibas, which published poems of only young writers and became a platform for young talents experimenting with various forms. Gangopadhyay was the founder editor. His first novel, Atmaprakash [Emergence], published in 1965 in the prestigious magazine Desh, was critically acclaimed though it triggered a controversy, with some calling it ‘obscene’.Among his well-known poems are Kavita Sangraha, Shada Pristha Tomar Sangay and Amar Swapna.In 1985, Gangopadhyay got the Sahitya Akademi award for his historical fiction Sei Somoy [Those Days].Among his other works are Pratham Alo [First Light], and Purbo-Paschim, a novel on the partition and its effect depicted through the eyes of three generations of Bengalis in West Bengal, Bangladesh and elsewhere.Besides the Sahitya Akademi award, Gangopadhyay got Ananda Purashkar, the Bankim Puraskar and Hindu Literary Prize.His thrillers of the Kakababu series were very popular among children and teenagers.Known for his liberal, secular and open-minded views, Gangopadhyay always spoke out against religious bigotry, and his pen was sharp in condemning the 1992 communal riots.Through his career, he used several pen names including Nil Lohit, Sanatan Pathak and Nil Upadhyay, each dwelling on a particular form and style of writing.Several of his novels were made into films by acclaimed directors. While Satyajit Ray did Pratidwandi and Aranyer Dinratri, Tapan Sinha made Sobuj Dwiper Raja, and Goutam Ghose directed the much-awarded Moner Manush based on the life of Baul singer Lalan Fakir.Gangopadhyay got a chance to put his vast knowledge of literature, particularly Indian literature, to good use when he took over as Sahitya Akademi president in 2008.Under him, the Akademi launched a large number of projects to popularise Indian literature across the world, translate works from one Indian language to another, and increase interaction between writers in various Indian languages. read more
