(Image: Michael Hammond)A UCT team, led by academic and medical specialist, Dr Llewellyn Padayachy, has pioneered a new, less invasive technique to inspect brain and intracranial pressure in children.While most brain monitoring techniques are invasive, time-consuming, require extensive infrastructure and often include drilling through the skull, Padayachy and his team have explored the potential of using ultrasound as a completely non-invasive, inexpensive, ubiquitous brain monitoring tool.Padayachy and his team have used this new method at the Red Cross War Memorial Children’s Hospital to significantly improve accuracy while decreasing the cost and labour intensiveness associated with traditional techniques.“Our study has demonstrated benefit in accurately assessing the pressure and blood flow dynamics of the brain,” said Padayachy. “By merely placing a small probe over the eyeball, we are able to use this natural window to the brain to better understand the intracranial milieu.”This method spares children unnecessary exposure to harmful radiation, anaesthesia and surgery and has the potential to be used nationwide, in clinics and hospital to detect brain conditions at an early stage.Video shows use of sound to view the brain“As a result of our committed use of this modality, we have subsequently developed a novel dynamic technique at the Red Cross War Memorial Children’s Hospital, which has significantly improved accuracy while potentially decreasing the cost and labour intensity associated with historically used techniques,” said Padayachy.The vast majority of children that Padayachy and his team treat come from the most impoverished and rural sectors of society, not only in the Eastern Cape but throughout the country and increasingly beyond South Africa’s borders, in sub-Saharan Africa. These children all share one uncomfortable problem: they always arrive for “brain inspection” later than they should have.“We have expanded the use of this non-invasive modality both as a neuro-navigation tool and as a diagnostic tool to facilitate early diagnosis in children with raised pressure in the brain,” said Padayachy.The study forms part of a collaborative research initiative between researchers at the University of Cape Town and the Norwegian University of Science and Technology (NTNU) and SINTEF. The work forms part of a doctoral thesis, supervised by Professor Graham Fieggen, Head of the division of neurosurgery at UCT.Source: University of Cape Town websitelast_img read more

Rural Ohio counties added to USDA StrikeForce Initiative

first_imgShare Facebook Twitter Google + LinkedIn Pinterest Agriculture Secretary Tom Vilsack visited the Ohio Union at The Ohio State University last week to announce the expansion of the USDA’s StrikeForce for Rural Growth and Opportunity Initiative into 11 high-poverty counties in Ohio. Launched in 2010, more than 1,500 StrikeForce partnerships have already helped USDA support nearly 190,000 projects and invest $23.5 billion in high-poverty areas in rural America.USDA’s StrikeForce delivers promising, sustainable results by building partnerships with community organizations, businesses, foundations, universities, faith-based and other groups to help challenged communities shape a future based on local assets and regional strengths. To date, StrikeForce technical assistance helping USDA invest nearly $7.5 billion into 970 counties across the U.S. to create jobs, build homes, feed kids, assist farmers and conserve natural resources in some of the nation’s most economically challenged areas.“If farmers in these Ohio counties are looking for additional credit, it becomes available through StrikeForce,” Vilsack said. “It also raises the awareness of some of our conservation programs, the micro-loan program and the high-tunnel house program. That raised awareness results in more loans being made.”StrikeForce was created to address persistent poverty across America. USDA identifies census tracts with over 20% poverty (according to American Community Survey data) to identify sub-county pockets of poverty. As areas of persistent poverty are identified, USDA staff work with state, local and community officials to increase awareness of USDA programs and help build program participation through intensive community outreach and technical assistance.“The next step is for our team at USDA to travel to the designated counties, sit down with local officials and ask them what they need in their area,” Vilsack said. “This has to be a bottom up system.”Currently, 85% of the country’s persistent poverty counties are in rural America. More than one-third of rural Americans and one-in-four rural children live in poverty.Finding uses for these new funds in the determined Ohio counties will begin with meetings that include officials from USDA, the Ohio Rural Development and Ohio Farm Service Agencies and the Natural Resource Conservation Service. Shortly thereafter, the process will transition to an outreach effort in the StrikeForce zones.“We’ll then survey local officials, businesses and stakeholders in those areas about what they think the biggest needs in their counties are,” said Tony Logan, State Director for USDA Rural Development for Ohio. “Then we’ll get to the drawing board and figure out which agency needs to apply their program dollars in each county.”Although many of the dollars tagged for the StrikeForce Initiative will go towards needs that may not be tied directly to agriculture, some will be used for issues related to the farm and used to aid in the water quality concerns in the state.“In Lucas county, these funds will be used to not only help with the poverty there, but also to start up some new conservation efforts in that county because of the recent water issues they have seen,” Logan said. “Farms across the state will also benefit with new farm loans for beginning farmers and veterans, which will be a sweat spot for the StrikeForce counties as well.”StrikeForce counties in Ohio include: Adams, Athens, Fayette, Guernsey, Jackson, Lucas, Meigs, Morgan, Pike, Scioto and Vinton.last_img read more

Google Confirms Trending Topics Test

first_imgWhy Tech Companies Need Simpler Terms of Servic… At Google, we run anywhere from 50 to 200 experiments at any given time on our websites all over the world. Right now, we are running a small test of a new Google News homepage design. More information about how Google runs experiments can be found [here].Google last redesigned its news page last May, adding more visual content to the layout. This time around, we expect to see more in the way of real-time content, including features such as the trending topics seen here.If you keep a close watch, it is possible you will see other new features that Google is testing, but as the company’s blog post points out, often these features will show up and go completely unnoticed. In Hobot’s case, the trending topics showed up for a brief period before disappearing again.We asked about the specifics of the new feature, but Gaither said that statement included above is all the company is saying about it at this time. Top Reasons to Go With Managed WordPress Hosting Tags:#Google#news#Real-Time Web#web mike melanson While none of us here at ReadWriteWeb have yet to see it in our Google News, a tip this morning from blogger Joe Hobot tells us that trending topics may be coming to the search engine’s news aggregator. We got in touch with Google this morning and a spokesman confirmed that the feature is indeed part of a series of experiments the company has been running since early this month. Image thanks to Joe Hobot. According to Chris Gaither, a spokesperson for Google, Search Engine Rountable first reported the potential feature’s appearence last Friday. Gaither said that trending topics are one of many experiments Google is conducting in their redesign of the news homepage.

How to Shoot, Edit, and Upload 360-Degree Videos

first_imgUploading a 360-Degree VideoUploading your video is not as easy as clicking upload and waiting. In YouTube, you will need to scrub the video through a 360-degree app. The video needs to include certain metadata for 360-degree playback to be enabled. YouTube has provided the following for all users to upload footage. Create a 360-enabled file with an appDownload the 360 Video Metadata app for Mac and WindowsUn-zip the file, then open the 360 Video Metadata app. If you’re on a Mac, you may need to right-click the app and then click “Open”Select the video fileClick “Inject and save”Enter a name for the file that will be createdSave the file. A new file will be created automatically in the same location as the original fileUpload the new file to YouTubeWait for the 360 degree effect to process. This may take up to an hour.Create a 360-enabled file with a scriptRather than using an app, you can use a Python script. Here’s how to do that. Download the ZIP containing the script using the “Download as ZIP” button at the bottom-right of this page. You’ll need to have Python installed on your computer to run it.Un-zip the file. In the 360-Videos-Metadata sub-folder, you’ll see the 360VideosMetadata.py script. From Terminal (Mac) or Command (Windows), run the script with this command:360videosmetadata.py -i [input] [output]Input is the full filename of the file that you’ve already created, for example: 360video.mp4. Output will be the name of the file that will be created by the script, so come up with a new name.The command you’ll run will look something like:360VideosMetadata.py -i 360video.mp4 360videoNEW.mp4If you’ve never run a Python script before, take a look at these resources for Mac and WindowsThe script will create a new file. Next, you’ll upload it to YouTube.Before publishing, you can verify that the file has 360-degree playback enabled by checking the video by watching it on your computer. It may take up to an hour for 360-degree playback to be available.Be sure not to make edits to the video itself using the YouTube Video Editor and Enhancements tools on desktop or mobile apps, as these tools don’t currently support 360-degree videos.Are you excited about 360 degree and VR filmmaking? How do you thing the technology might be best applied? Let us know in the comments below. Get ahead of the curve by learning how to produce 360-degree content for mobile devices and VR headsets. Here are the tools you need to shoot, edit, and upload 360-degree videos. 360-degree videos have now been released to the masses via YouTube and Facebook. Prior to that, you had to have a VR developers kit and share your work with other developers. Now that any user has the ability to upload and share content, let’s take a look at a few ways you can start producing 360-degree videos. 360-Degree Cameras and RigsAs this is a developing technology, there are a ton of options available and in development. If you are planning on purchasing a single camera, you should note that only some sites can host your video. Currently YouTube is only compatible with four camera options; Ricoh Theta, Kodak SP360, Giroptic 360cam, and IC Real Tech Allie. With these cameras, you are looking to invest $300 – $500. (Not all are available to the public yet.)The other option you have is to build your own rig. The most widely used camera rigs use a series of GoPro cameras. The most common rigs feature at least six GoPro cameras in a 3D printed rig. Google Jump uses 16 GoPro cameras.These rigs will cost thousands of dollars, depending on which GoPro camera you decide to use. The benefit of GoPro is that the cameras are reliable. They have been tested for years in extreme conditions, and they have been designed to be the ultimate camera for any condition.Here is a quick interview about a team that mounted a rig on an Indy car.When shooting with one of these cameras or rigs, remember that 360-degrees means everything will be in view — every detail of the room, the camera operator, any equipment, etc. Be sure you take that into account when deciding on a location. You will also need to make sure you have suitable and consistent lighting to make sure all of the footage matches.Editing 360-Degree VideoOne of the most popular 360-degree editing platforms, which is also YouTube compatible, is the Kolor Autopano Video software.  The Kolor Autopano Video platform works on both Windows and Mac. It automatically syncs your footage and stitches a 360-degree video. You also have the ability to render in HD, 4K, or even export individual frames.Here’s how to use the latest version of the software (2.2).To see what skydiving footage looks like in 360 degrees, check out this Land, Air, and Sea video from GoPro. On desktops, you will need the Chrome browser. You can control the video by using your mouse or the keyboard letters W, A, S, D.last_img read more

Nagaland recalls all police personnel on leave

first_imgThe Nagaland government has recalled all police “officers and personnel on leave” amid fears in the State about a possible breakdown of the peace process.On Monday, the office of Nagaland’s Director-General of Police issued a wireless transmission message to all unit heads banning all kinds of leave.The office of the State’s Chief Secretary issued a similar message asking all Deputy Commissioners and Administrative Officers to remain in station and recall all officers not on medical or maternity leave.The recalling of all police personnel has come three days after the Centre rejected the twin demands of the extremist Isak-Muivah faction of National Socialist Council of Nagaland (NSCN-IM) for a separate “Naga national flag” and “Naga Yezabo” (constitution).The Centre and NSCN-IM have been pursuing a peace process since signing a ceasefire in August 1997.last_img read more
