Calcium source

first_imgGetting enough calcium to keep bones from thinning throughout a persons life may be made more difficult if that person has lactose intolerance or another reason, such as a tendency toward kidney stones, for avoiding calcium-rich food sources. Calcium deficiency also effects the heart and circulatory system, as well as the secretion of essential hormones. There are many ways to supplement calcium, including a growing number of fortified foods.Review Date:11/15/2012Reviewed By:C.

ISL: Atletico de Kolkata pip Mumbai City FC 3-2 in semi-final first leg

first_imgFormer champions Atletico de Kolkata (ATK) edged past ten-man Mumbai City FC 3-2 in a rip-roaring semi-final first leg of the Indian Super League at the Rabindra Sarovar Stadium on Saturday.This was ATK’s second home win this season.ATK took the lead in the third minute through Lalrindika Ralte but soon fell behind to two goals from Mumbai’s Leo Costa and Gerson Viera.But the fate of the match swung rapidly in the hosts’ favour with Iain Hume striking a brace (39th and 45+4) towards the end of the first session.Mumbai’s Diego Forlan was sent off in the 74th minute after a double booking. The 2010 World Cup Golden Ball winner was booked first in the 51st minute.ATK play in Mumbai for the second leg next Tuesday.To the surprise of all, Jose Molina ringed in six changes with the likes of Debjit Mazumder — one of their key performers under the bar — finding a place on the bench.Mumbai, on the other hand, handed Leo Costa and Sunil Chhetri starts in place of Matias Defederico and Udanta Singh.ATK started as the brighter side and got their reward when the match was three minutes old, albeit from fortuitous circumstances.Borja Fernandez’s cross from the right found Ralte who knew little about his looped flick which cushioned into the top right corner, making it difficult for Amrinder to gauge.The hosts’ joy was shortlived though as the visitors drew level seven minutes later.Forlan’s free kick found Chhetri, who nodded the ball in the path of Costa for the Brazilian to slot it in.advertisementThe boisterous 12,500 crowd was stunned to silence moments later when the blue shirts took the lead.ATK’s sloppy defending was for all to see as Gerson Viera banged in a Forlan inswinging free kick with Henrique Sereno caught napping.Fernandez came close to equalising soon after the setback but his effort flew over.He was in the thick of things again when Hume headed back for Doutie to shoot on the half volley. Thankfully, Goian was at the right place at the right time to get an important deflection for keeper Amrinder to save.Just when it looked like Mumbai would go into the break with their noses ahead, ATK not only restored parity but went ahead for the second time in the game.Hume scored both the goals. First Ralte crossed from the byline for Doutie to set up Hume after Amrinder only got his fingertips to the ball. Hume then smashed home as Amrinder was left stranded.In the first half added time, Lalhmangaihsanga Ralte tripped Postiga inside the box to concede a penalty which Hume comfortably tucked in to the keeper’s right.After the breather, Hume and Chhetri were guilty of wasting two good chances.It became an uphill task for Mumbai when their star player Forlan saw his second yellow card of the game for kicking Jewel Raja after the Uruguayan failed to win a duel with him.Sehnaj Singh got into the referee’s book soon after as Mumbai seemed to be losing their cool.Hume came close in the dying minutes of the game, but his fizzing shot finished off-target.last_img read more

The unique challenges of IoT app development

Developers must be aware of key issues that significantly impact the way software is designed and built for the IoT. Some are new challenges, some require a more back-to-basics approach that focuses on key principles which may have been forgotten or overlooked in recent years.With the majority of devices running on battery power, energy efficiency is hardwired into the DNA of the IoT. There’s a huge diversity of hardware that forms the IoT ecosystem with most devices run on SoCs, so you can’t build a huge code base. Code must be optimised to ensure every instruction counts.It may be necessary to add components which proactively monitor and manage the system, for example matching capacity to periods of peak demand or running processes when maximum energy or bandwidth are available. It’s also important for apps to have built-in flexibility. That means using concurrent coding, enabling tasks and algorithms to be carried out simultaneously rather than sequentially, while remaining determinate. Many programmers are more used to writing sequential code, so may have to acquire new design patterns.One of the greatest concerns for developers targeting the IoT is security. We’re all aware of recent high-profile security problems involving big companies such as Talk Talk and Yahoo. In response to potentially damaging repercussions, companies such as Apple are adopting a policy of paying if a security bug in their offerings is identified.Retrospective add-ons are not the answer. It’s vital that robust security is taken into account right from the get-go. Involving a security conscious developer in the pre-project planning will ensure safeguards are embedded into the design of the core features and functionality of the app.Human security is equally important. Installers and end users will need adequate training and monitoring capability to ensure that high security levels are maintained.IoT devices are often controlling vital services and one simple glitch can cause major disruption. Therefore, IoT app developers need to concentrate even more effort on review and testing, putting in place robust verification procedures at key stages during the product development cycle. In addition, resilience is often mission-critical. Fault finding and evaluation should be essential parts of the post-installation support function.One of the main challenges that mobile app developers have had to overcome is cross-platform compatibility. In the IoT world, that challenge is on a whole new level, with a much wider variety of devices, many without traditional interfaces such as screens or trackpads. In many IoT devices you are simply relying on sensors for functionality. Building a user experience around sensors can be challenging and requires the programmer to have the skills and knowledge to make the coding effective.An app which controls an IoT device must enhance the user’s lifestyle, not complicate it. If you’re designing a program that contributes to aspects of people lifestyle, simplicity is what it’s all about.This is an exciting time to be a developer. More and more businesses are embracing the IoT concept and are looking for expert programmers to help them take full advantage of real-time data available from billions of connected devices. Being aware of and ready for the challenges is the first step to success in this massive global marketplace.— Mark Thomas is CEO of Coderus, a software development company in the U.K. Originally published on Embedded’s sister site, EE Times: “IoT apps pose unique challenges .” last_img read more
