Sandton gets a taste of real Mzansi

first_imgShe said the shop offered a unique balance of sustainable business growth, marketing and quality benchmarking, while at the same time inspiring, training and assisting local entrepreneurs, artists and the like. The collection ranges from contemporary crafts, homeware, cutlery and kitchen ware, to handbags, all with an African look and feel. It also includes items from Gift in Cape Town. She said the shop represented a new mindset and approach to the ever-expanding demand for South Africa signature items. “The collection supports small workshops in townships or rooms in rural villages. The Mzansi Collection shop will be open until Tuesday, 16 December, when it will close for renovations. It is expected to re-open permanently in January. Partners include the City of Johannesburg, Jobs for Growth, the Independent Development Trust, the Small Enterprise Development Agency, the Gauteng provincial government, Proudly South African, and the departments of Trade and Industry, Arts and Culture, Water Affairs and Forestry, and Agriculture. The Mzansi Collection shop, which sells only proudly South African products, has opened at Nelson Mandela Square, in the luxury shopping mecca of Sandton in Johannesburg. The Mzansi Collection is a joint initiative bringing together all three government levels, and the concept is spearheaded by the Department of Trade and Industry. “This store is just spectacular and stunning because it showcases the diversity of our country,” said Department of Trade and Industry creative industries director Nadia Sujee. 8 December 2008 “The Mzansi Collection store has two main objectives: firstly, to promote sustainability, jobs, inspiration and growth by encouraging and motivating the under-privileged to become business leaders in their own right; and secondly, the brand aims to attract a high-end market of international and local customers,” Deputy President Baleka Mbete said at the opening on Friday. “We are really proud of this store, and we hope that it bridges the gap between the rural producers and national and international markets,” Sujee said. Also in stock is fine jewellery inspired by the township game morabaraba, and Zulu Lulu’s quirky ceramic Dlamini doll, Sophy the Ndebele beaded Christmas angel, and Sesfikile Rainsong pinotage. Everything is made in South Africa. Source: City of Johannesburglast_img read more

Designing a Low-Slope Roof That Works

first_imgThe recessed can light conundrumThere is yet another wrinkle to this roofing saga: the use of recessed light fixtures in the ceiling. They would be installed in the drywall that serves as the air barrier. Hoene wonders if that’s going to be a problem.Holladay says, “Absolutely, that’s a problem.”He continues, “You want to minimize all penetrations and electrical boxes in an airtight ceiling, and all penetrations need to be very carefully air sealed. If you care about energy performance, you won’t have any recessed can lights in your ceiling.”Dorsett adds that certain types of recessed lights come with gaskets to make them airtight, and they are rated for contact with insulation. But, he says, they should be inspected and installed carefully.“There are also surface-mount LED fixtures that can be mounted on standard electric boxes that present a far smaller and far shallower penetration into the insulation layer, which may be a better alternative,” Dorsett says. “Any penetration of the ceiling gypsum needs to be detailed for air tightness.” Insulating Low-Slope Residential RoofsHow to Install Rigid Foam On Top of Roof SheathingSpraying Polyurethane Foam Over an Existing RoofQuestions and Answers About Air BarriersBan the CanRethinking Recessed LightingCold-Weather Performance of PolyisocyanurateGreen Basics: Rigid Foam Insulation Calculating the Minimum Thickness of Rigid Foam SheathingHow to Build an Insulated Cathedral CeilingAll About Attic VentingGreen Basics: Attics, Structure, Claddings RELATED ARTICLES Our expert’s opinionHere’s how GBA Technical Director Peter Yost sees Hoene’s situation:Per usual on roofing and attic questions, I like to check in with Brian Knowles at RoofsPlus, a local high-performance roofing company. Here is a summary of my discussion with Brian:Is a 1:12 standing seam roof OK? Yes, but use a full-coverage membrane such as Ice and Water Shield as the roofing underlayment. Also, use a hidden-clip system rather than exposed fasteners, and back up the standing seam lock seam with a high-performance sealant. Brian’s company uses Geocel Tripolymer.Using an EPDM membrane would be OK as well. But, exposed roofing membranes typically don’t fail in the field of the installation, but at joints and laps. These need to be inspected annually. Brian’s company never uses 45-mil membranes but finds the 60-mil performs well. They have never used 90-mil EPDM.For both types of cladding, the devil is in the details at the eaves: With a slope this low, making a watertight seal between either the membrane or the standing seam and the fascia is tricky, particularly if the site has wind exposure. Brian has found that even manufacturers’ recommended eave details are not robust and his company has developed some of their own details.Here is Brian’s cut: “Fully adhered EPDM systems (where there is no curb or parapet termination) need to be stripped in to metal drip edge with cover tape. The published details will show the EPDM fastened under the drip edge metal. They show cover tape over the drip edge and onto the EPDM. This detail leaves the strip of cover tape vulnerable to damage from sliding ice and snow. Our manufacturer trainers have approved a slightly different detail that has a more successful field application in areas where ice and snow are a factor (see Image #3, below). Bear in mind that these edge details will require regular inspection over the years to maintain the bond at the edge. A parapet or curb detail is preferred when using EPDM.”Color matters. In cold climates, white membranes and white metal roofs can be associated with significant night-sky radiation and much cooler attic spaces.On the question of whether to vent the roof assembly: A dedicated space of 1 to 2 inches just underneath or above the structural roof sheathing will vent the assembly. The space created between the structural roof deck and the finished ceiling is an attic space. This space can be vented along any of the margins of the attic but typically with vents at the eaves or sometimes rooftop turbine or “whirlybird” vents. Brian and I agree that the attic (or in this case almost a plenum) space needs to be either completely inside or outside the conditioned space and it needs air flow in either case. But note: If the attic is outside, then it means venting it with outside air; if the attic is inside, then it means introducing inside air flow. (Read on for more details…)In Brian’s experience, even though a 1:12 pitch gives you negligible stack effect air movement or venting, when the roof cladding — particularly a darker one — is exposed to solar gain, that attic space heats up quite a bit and air flow develops even without stack effect from eave to eave or eave to ridge. So, the “high-low” eave vents in the second hand-drawn image will work fine for venting this “outside” attic space. And of course in this case, the finished ceiling plane is where the continuous air and thermal boundaries will be.On the other hand, you could insulate and air seal this roof at the roof line, in which case the attic space created between the roof and the ceiling plane becomes an inside space. It’s important to create air flow for this space, even if it is just passive vents that relieve this space.But note, if you air seal and insulate the finished ceiling plane, then the roof assembly above can dry to the interior. On the other hand, if you insulate and air seal the roof line, and you don’t vent the underside or topside of the structural roof deck, then you’ll have little to no drying potential in either direction. What kind of insulation will work best?Hoene’s original plan was to use 4 inches of XPS, which has a nominal R-rating of 5 per inch. Better take that with a grain of salt, Dorsett says.“Four inches of XPS won’t perform at R-20 for the full 50+ year lifecycle of most metal roofing,” he writes. “As it loses its blowing agent over a handful of decades its performance starts out higher than R-20, but eventually drops to about R-17. The R-5/inch labeling is based on something like a 20-year average performance.“R-17 might be sufficient for dew-point control, but it might not be,” he continues. “If instead you went with 5 inches of EPS [expanded polystyrene], its R-value will be pretty much the same on day 25,000 as on day 1, since its much lighter blowing agent dissipates quickly, and its labeled-R is its fully depleted R.”There are two other choices — polyisocyanurate and spray polyurethane foam.“Another roofer has proposed using 4.4 inches of polyiso insulation above the sheathing for an unvented assembly,” Hoene writes. “This builder said that XPS and EPS aren’t compatible with the EPDM adhesive. Quote from builder: ‘Like pouring gas in a styrofoam cup, it melts it away. They are typically used in ballasted or mechanically attached systems.’“The issue I have with polyiso is that I have read that the effective R-value in cold weather is lower, and polyiso should only be used in warmer climates,” he adds.One solution to polyiso’s less-than-optimum performance in cold weather, Holladay says, comes from building scientist John Straube, who once told him, “One option is to stick with polyiso and just make it thicker. If we do that, let’s call polyiso R-5 per inch.”Either open- or closed-cell polyurethane foam could be sprayed on the underside of the roof sheathing, another possible route to take. Choosing the type of roofingA first step, Holladay suggests, would be finding out whether the type of metal roofing Hoene is considering can be installed on the roof he’s planning. The pitch is very low — rising only 1 inch for every 12 inches of run — and some types of metal roofing need more than that.Hoene has discussed the possibility of using 60-mil EPDM instead, which apparently won’t present any aesthetic issues, but he wonders whether the membrane will perform as well as a standing-seam metal roof.“On low-slope roofs in the snow zone, EPDM will work better than standing-seam metal, since it can’t leak even under high winds, whereas metal roofs will,” writes Dana Dorsett. “With limited slope to drain well, it can take forever to be rid of any leakage moisture. EPDM won’t last as long as metal, but there’s a reason it’s the most common roofing for very low slope roofs.”Kevin Dickson also likes EPDM. It’s “great,” he says, and it’s available in white, which would reduce cooling loads in the house.An alternative, Dickson adds, is spray polyurethane, which will last “indefinitely” if it’s well maintained, meaning that it should be recoated every 10 years or so, and inspected carefully every year.In further conversations with a roofer familiar with low-slope assemblies, Hoene is told that a fully adhered 90-mil EPDM roof applied over 1/2-inch DensDeck Roof Boards is the best option.“Is the 90-mil thickness overkill?” he asks. “Most of the applications I have read about use 60-mil or 75-mil, but we do want a roof built to last.” After reading a couple of articles on the topic by GBA Senior Editor Martin Holladay, Hoene is leaning toward an unvented roof assembly (see the sketch above), which would include cellulose insulation in the rafter bays and 4 inches of extruded polystyrene (XPS) rigid insulation above a layer of airtight sheathing. That would be followed by a second layer of OSB or plywood sheathing and, finally, the metal roofing.“Does the diagram look like a good approach?” he asks. “Any details that I should pass along to our builder about the roof trusses?”Those questions are the start of this Q&A Spotlight. If only Kevin Hoene’s choices for a new roof boiled down to a choice between an EPDM membrane and metal, his life would probably seem a whole lot simpler.But Hoene, building a new home in Illinois and on the boundary between Climate Zones 4 and 5, will soon be weighing the pros and cons not only of different roof coverings, but also of what type of insulation to use, whether it should go above or below the roof sheathing, and whether the roof should be vented or unvented. In other words, nothing seems off the table.“Our house is being built near the boundary of Zone 4 and 5 in Illinois with a 1:12 pitch metal roof,” Hoene writes in a Q&A post at GreenBuildingAdvisor. “I’ve done a lot of research on low-slope roofs because our builder does not have a lot of experience with flat roofs.” Where should the insulation go?Hoene has sketched an unvented roof assembly, but his builder and roofer both suggest he consider a vented roof assembly (see Image #2 at the bottom of the page).“They have not done an unvented roof with the layered foam above the sheathing and seem more comfortable doing the following approach and say it would save a lot of money in time and materials,” Hoene says.The builder suggests blown-in cellulose 16 inches deep, leaving the area above the insulation open for ventilation. Hoene adds: “He recommended no venting in the center of the roof due to more chances for leaks.”“It might be time to find a different roofer,” Holladay replies. “If you can locate a roofer familiar with commercial construction, you’ll be in better hands — because installing rigid foam above the roof sheathing is a standard method of insulating low-slope commercial roofs.“The approach shown in your sketch is associated with failures, because there isn’t enough of a difference in elevation between the ‘inlet’ vents and the ‘outlet’ vents. I call this type of ventilation ‘faith-based venting.’ Air rarely follows the ‘smart arrows’ that some designers draw to indicate where the air is supposed to enter, and where it is supposed to leave.”The same roofer who has suggested 90-mil EPDM also would prefer keeping all of the insulation below the sheathing. Hoene says he would insulate from below using blown-fiberglass with some sort of adhesive that allows it to bond with the decking, or to use spray foam.Holladay is unconvinced. “I stand by my advice,” he says. “For an unvented flat roof, you want at least some — or ideally, all — of the insulation to be above the roof sheathing. That way, the roof sheathing stays warm and dry.”last_img read more

Valencell, STMicroelectronics launch biometric wearables devkit

first_imgWhy IoT Apps are Eating Device Interfaces How Myia Health’s Partnership with Mercy Virtua… Follow the Puck Tags:#Internet of Things#IoT#STMicroelectronics#Valencell#wearables Donal Powercenter_img Biometric wearables technology got a boost with the launch of a new development kit that improves accuracy and scalability.The new devkit was announced by chipmaker STMicroelectronics (ST) and Valencell, a maker of biometric data sensor technology.The development kit is aimed at accelerating the development of smart wearable and Internet of Things (IoT) products.The kit will involve ST’s SensorTile multi-sensor module that incorporates various IoT capabilities. The tiny module includes a Bluetooth Low Energy chipset, various motion and environmental MEMS sensors, a digital MEMS microphone and a powerful STM32L4 microcontroller.The kit will also include the Valencell Benchmark biometric sensor platform in order to support the development of advanced wearable products.“Valencell’s Benchmark solution leverages the high accuracy of ST’s MEMS sensor technology along with SensorTile’s miniature form factor, flexibility, and STM32 Open Development Environment-based ecosystem,” said STMicroelectronics’ Tony Keirouz. “Combined, SensorTile and Benchmark enable wearable makers to quickly and easily develop the perfect product for any application that integrates highly accurate biometrics.”Valencell aiming for simpler prototypingThe integration of Valencell’s Benchmark sensor tech with ST’s SensorTile development kit is aimed at simplifying the prototyping and evaluation of new wearable IoT products.“Working with ST has allowed us to bring together the best of all sensors required to support the most advanced wearable use cases through our groundbreaking Benchmark sensor system,” said Valencell president Steven LeBoeuf.”What attracted us to the SensorTile was the flexibility of the platform and the ultra-low power consumption, which will enable our customers to create highly-accurate and powerful wearables and hearables in any form factor.”The collaboration comes against the backdrop of a cooling wearables market in North America and an improving wearables outlook in China.In fact, an earlier report indicated that China may become the world’s largest wearable customer in 2017, if sales continue to surge as they have in 2016. In the past year, the country has seen an 84% increase in wearable sales, reaching 9.5 million between April and June this year.1Analyst firm IDC predicted 101 million wearable sales in 2016. Chima might take 30% of the entire wearable market in the next year, if sales in North America and Europe remain the same.

I-T officials raid house, offices of senior NCP leader Hasan Mushrif in Kolhapur

first_imgA team of the Income Tax Department on July 25 raided the residence and factory premises of senior Nationalist Congress Party (NCP) leader and legislator Hasan Mushrif in Kolhapur district in western MaharashtraAn MLA from the Kagal Assembly seat, Mr. Mushrif, a former Minister who held the Labour portfolio in the erstwhile Congress-NCP government, is considered to be a tall leader of his party in the State’s ‘sugar belt’ region.According to sources, the I-T team swooped down on Mr. Mushrif’s bungalow in Kagal at around 5.30 a.m. while simultaneous raids took place at his son’s residence in Pune and his relatives’ house in Takala in Kolhapur.Officials also conducted searches at the Sar Senapati Santaji Ghorpade Sugar Factory in Kagal which is said to be controlled by Mr. Mushrif among other places.However, authorities declined to elaborate on the reason for the raids.A number of the NCP leader’s loyalists thronged outside his house to express solidarity as news of the raids spread throughout Kagal. A robust security shield was in place as the I-T officials conducted their searches and scrutinised documents at Mr. Mushrif’s house and office.The raids coincide with the exit of another important NCP leader Sachin Ahir, who jettisoned his position as his party’s Mumbai unit chief to enter the Shiv Sena, allegedly impressed with Aditya Thackeray’s leadership.The timing of the raid on Mr. Mushrif’s home has triggered speculation that the NCP leader’s alleged ‘refusal’ to join the ruling Bharatiya Janata Party (BJP) prompted the party to unleash the I-T Department on him.“Recently, at a public function in Kolhapur, newly appointed BJP State president Chandrakant Patil had made an open offer to Mr. Mushrif to ally with the BJP. But the NCP leader had snubbed Mr. Patil and instead questioned as to how, and from where, was the BJP able to secure enormous funds to ‘buy’ Congress legislators in Karnataka and destabilise the Congress-JD (S) government,” said an analyst, requesting anonymity.The raids on Mr. Mushrif’s house also come amid intense speculation of another NCP MLA, Vaibhav Pichad from Akole in Ahmednagar district, entering the BJP fold.Mr. Pichad, the son of senior NCP MLA Madhukar Pichad, is believed to have met with Chief Minister Devendra Fadnavis at the latter’s home ‘Varsha’ in Mumbai on Wednesday evening.The developments take place a week after Mr. Patil had confidently claimed that several legislators from the opposition NCP and the Congress were in contact with the BJP. Mr. Patil had also said that the opposition camp would witness a spate of resignations in the coming week.last_img read more

Traveler’s diarrhea diet

first_imgDefinitionTravelers diarrhea is loose, watery stools. People can get travelers diarrhea when they visit places where the water is not clean or the food is not handled safely. This can include third-world or developing countries in Latin America, Africa, the Middle East, and Asia.This article tells you what you should eat or drink if you have travelers diarrhea.Alternative NamesDiet – travelers diarrhea; Diarrhea – travelers – dietFunctionBacteria and other substances in the water and food can cause travelers diarrhea. People who live these areas dont often get sick because their bodies are used to the bacteria.You can lower your risk for getting travelers diarrhea by avoiding water, ice, and food that may be contaminated. The goal of the travelers diarrhea diet is to make your symptoms better and prevent you from getting dehydrated.Side EffectsTravelers diarrhea is rarely dangerous in adults. It can be more serious in children.RecommendationsHow to prevent travelers diarrhea:WATER AND OTHER DRINKSDo not use tap water to drink or brush your teeth.Do not use ice made from tap water.Use only boiled water (boiled for at least 5 minutes) for mixing baby formula.For infants, breastfeeding is the best and safest food source. However, the stress of traveling may reduce the amount of milk you make.Drink only pasteurized milk.Drink bottled drinks if the seal on the bottle hasnt been broken.Sodas and hot drinks are usually safe.FOODDo not eat raw fruits and vegetables unless you peel them. Wash all fruits and vegetables before eating them.Do not eat raw leafy vegetables (e.g. lettuce, spinach, cabbage) because they are hard to clean.Do not eat raw or rare meats.Avoid shellfish.Do not buy food from street vendors.Eat hot, well-cooked foods. Heat kills the bacteria. But do not eat hot foods that have been sitting around for a long time.WASHINGadvertisementWash hands often.Watch children carefully so they do not put things in their mouths or touch dirty items and then put their hands in their mouths.If possible, keep infants from crawling on dirty floors.Check to see that utensils and dishes are clean.There is no vaccine against travelers diarrhea.Your doctor may recommend medicines to help lower your chances of getting sick.Taking two tablets of Pepto-Bismol four times a day before you travel and while you are traveling can help prevent diarrhea. Do not take Pepto-Bismol for more than 3 weeks.Most people do not need to take antibiotics every day to prevent diarrhea while traveling.People who are at risk for more dangerous infections (because chronic bowel diseases, kidney disease, cancer, diabetes, or HIV) should talk to their doctor before traveling.A prescription medicine called rifaximin can also help prevent travelers diarrhea. Ask your doctor if this medicine is right for you.If you have diarrhea, follow these tips to help you feel better:Drink 8 to 10 glasses of clear fluids every day. Water or an oral rehydration solution is best.Drink at least 1 cup of liquid every time you have a loose bowel movement.Eat small meals every few hours instead of three big meals.Eat some salty foods, such as pretzels, soup, and sports drinks.Eat foods that are high in potassium, such as bananas, potatoes without the skin, and fruit juices.Dehydration means your body does not have as much water and fluids as it should. It is a very big problem for children or people who are in a hot climate. Signs of severe dehydration include:Decreased urine (fewer wet diapers in infants)Dry mouthSunken eyesFew tears when cryingGive your child fluids for the first 4 – 6 hours. At first, try 1 ounce (2 tablespoons) of fluid every 30 to 60 minutes.You can use an over-the-counter drink, such as Pedialyte or Infalyte. Do not add water to these drinks.You can also try Pedialyte popsicles.Fruit juice or broth with water added to it may also help. These drinks can give your child important minerals that are being lost in the diarrhea.If you are breastfeeding your infant, keep doing it. If you are using formula, use it at half-strength for two to three feedings after the diarrhea starts. Then you can begin regular formula feedings.In developing countries, many health agencies stock packets of salts to mix with water. If these fluids are not available, you can make an emergency solution by mixing:1/2 teaspoon of salt2 tablespoons sugar or rice powder1/4 teaspoon potassium chloride (salt substitute)1/2 teaspoon trisodium citrate (can be replaced with baking soda)1 liter of clean waterGet medical help right away if you or your child has symptoms of severe dehydration, or if you have a fever or bloody stools.advertisementReferencesArguin P.
