SHARJAH, United Arab Emirates, (CMC):Not even a sensational beaver-trick by former Jamaica and West Indies left-arm seamer Krishmar Santokie could prevent Gemini Arabians from pulling off a 12-run victory over Sagittarius Strikers in the Masters Champions League here yesterday.The 31-year-old, who played the last of his 12 Twenty20 Internationals two years ago, grabbed four consecutive wickets off the first four balls of the final over to help restrict a rampant Arabians to 224 for seven off their 20 overs at the Sharjah Cricket Stadium.Opting to bat first, Arabians were propelled by Indian opener Virender Sehwag who belted 134 off 63 balls, with ten fours and 11 sixes.He put on 86 for the first wicket with South African Jacques Rudolph who hit 27 and a further 135 for the second wicket with Sri Lankan Kumar Sangakkara who scored 51 from 33 deliveries.Recently retired West Indies left-hander Shiv Chanderpaul was unbeaten on one from two deliveries at the end.SUPERB OVERSSantokie, who had taken one wicket in an earlier spell, finished with five for 30 in a superb four-over spell to be the leading bowler for Strikers.He bowled Sangakkara with the first ball of the over and then proceeded to remove Brad Hodge, Justin Kemp and Naved-ul-Hasan all without scoring, while conceding just one run from the final over of the innings.In reply, Imran Farhat stroked 52 from 32 deliveries, Yasir Hameed, 41 from 22 balls with a four and four sixes and Yasir Arafat a 16-ball 32 with four sixes, but Strikers still slumped to 177 for nine in the 18th over.However, Santokie arrived to smash an unbeaten 23 from nine balls with three sixes in a 35-run, last wicket stand with Shane Bond who got 12 not out, as Strikers came up short in the end.
28 March 2008South African chemical, mining and agricultural company Omnia has entered into an agreement with the International Finance Corporation to sell up to one million carbon credits over the next five years, in a deal worth some €15-million (about R188.5-million).The IFC, a member of the World Bank Group, will purchase the carbon credits, known formally as Certified Emission Reductions (CERs), from Omnia Fertilizer and sell these on to international buyers.“The IFC has committed to purchase a minimum 50% of all Omnia’s CERs for the next five years and will guarantee the delivery of the credits to potential buyers,” Omnia said in a statement last week.The Clean Development Mechanism of the Kyoto Protocol has established CERs as an asset that can be traded in global markets and aims to decouple economic growth from greenhouse growth.“IFC places a strong emphasis on environmental and social sustainability and is eager to work with companies who want to undertake climate friendly projects and commercialize carbon assets,” said IFC Southern Africa manager Saleem Karimjee. “We hope that Omnia’s move will encourage other companies in Africa to also reduce their greenhouse gas emissions.”Clean Development MechanismOmnia Fertilizer will generate approximately 420 000 CERs per annum at its Sasolburg plant, through the installation of a nitrous oxide destruction facility at its nitric acid plant, which will significantly reduce the plant’s nitrous oxide emissions.Greenhouse gas emissions, including nitrous oxide, are believed to be the cause of global climate change.Omnia announced the approval of the Clean Development Mechanism plant in August last year, and the plant, which uses German-developed Uhde technology, is now fully operative.The carbon credits Omnia’s plant will produce are expected to add R60-million to the group’s revenue annually, based on the current price of CERs, which is currently approximately €15 per ton.“The construction of our nitrous oxide destruction facility underlines Omnia’s commitment to sustainable development and reflects the group’s focus on improving all areas of our environmental management,” said Omnia Fertilizer MD Trevor Grant. “We believe IFC, with its AAA-rating and experience in the carbon trading market, is an ideal partner to assist us in generating strong revenue from the carbon credits we will generate.”SAinfo reporterWould you like to use this article in your publicationor on your website?See: Using SAinfo material
I Am An Entrepreneur was a platform for small business owners and successful entrepreneurs and investors to talk about funding and lessons learned.Kgosi Diphokwane, Mpho Mashishi, Sifiso Ngcobo and Tshepo Mothibe attend I Am An Entrepreneur in Johannesburg on 19 November 2016. (Images: Melissa Javan)Melissa JavanFunding for small businesses – and how to access it – was a hot topic at I Am An Entrepreneur (IAAE), held on Saturday 19 November 2016 in Johannesburg.The event coincided with the Global Entrepreneurship Week, was held at the Industrial Development Corporation (IDC) head office in Sandton. The IAAE, which is hosted across the country, is organised by Ignite South Africa and My Start Up South Africa.The Johannesburg event was the seventh edition of the IAAE. Small business owners were invited to engage with successful entrepreneurs about their journeys, and to share lessons learned.The IAAE has been to Kimberly, Polokwane, Cape Town, Durban and Johannesburg, which was the last leg of the year.Brand South Africa’s Play Your Part initiative is a sponsor of IAAE.The guestsThe speakers on Saturday were Ran Neu-Ner, co-founder of The Creative Counsel; Sonja de Bruyn Sebotsa, co-founder of Identity Partners; and Given Mkhari, CEO of MSG Afrika Group. Among the guests in the audience were comedian David Kau and fashion designer Theo Ngobeni.Lynette Ntuli, CEO of Innate Investment Solutions and founder of Ignite SA, and radio presenter Andile Khumalo of Power FM 98.7 were the masters of ceremony.Do homework on yourselfMkhari advised that each small business owner should master himself and his trade. “Ask yourself how you can differentiate yourself.“Do your homework about yourself and your abilities. You can’t lead people or in an industry, if you can’t lead yourself,” he said.“If you don’t buy it [the business idea] with your own money, or skills, then why should I buy it?”Humans were driven by self-interest, he added. “Only non-government organisations and some churches help people. Get rid of that idea that someone will fund you.“Funders don’t fund people who need the money. They fund people who will give them a return.”He warned that entrepreneurs should be wary before taking risks. “Take a chance like a coward – I do research before I take a risk.”Andile Khumalo, master of ceremony, prompts Ran Neu-Ner of The Creative Counsel and Sonja de Bruyn Sebotsa of Identity Partners to share the ups and downs of their entrepreneurial journeys at I Am An Entrepreneur on Saturday 19 November 2016.What do you do when you fail?Neu-Ner agreed with Mkhari’s sentiments, saying entrepreneurs should invest in their businesses if they believe in it.“I get about 100 emails a week from people who want me to fund them, because they have an idea [for a business].“I just send these individuals a one liner with the following questions: how much revenue has your business done, and how much money have you invested in it?” He hardly got responses to that email.Neu-Ner also advised that taking chances and failing would help to build your character. If you continuously failed to impress funders, you should tweak your business plan. “Question your business model — how can you make your business model better.”Use your skillsDe Bruyn Sebotsa said that the skills she obtained from working in a corporate environment became her toolkit. “Don’t discount the skills and development you get from working in a corporate environment. You can bring that structure and form into a new environment.“It can also give you confidence to start your own business.”It was difficult for a funder to give money to someone who had not worked in a structured environment, she added.When a member of the audience spoke about seeking funding for her poultry farming venture, the speakers advised her to look into collaborating with a farmer who already owned land.De Bruyn Sebotsa asked her: “Have you cultivated relationships and networks? Also, why are you in the poultry business?”The guests gain new insight at I Am An Entrepreneur on Saturday 19 November 2016.“Your idea must be hot!”Khumalo advised that entrepreneurs should tell funders such as the IDC how their business would benefit the development of South Africa. “Show that this business is going to create jobs. Your idea must a hot idea. It must be awesome that it’s going to stick.”“Show the world what we can do”Manusha Pillai, the general manager: communications at Brand South Africa, said the organisation was to be part of the IAAE initiative.Building the nation brand rested on each citizen. The IAAE was important, she said because it was a place where entrepreneurs could find their space and engage with each other.Pillai said she hoped the IAAE would help South Africa achieve its vision of the National Development Plan 2030. “We want an inspired, passionate South Africa. This is so that we can show the world what we can do.“Play your part and show what South Africa you want… You each contribute what South Africa will look like.”Other sponsors were the IDC, Renault South Africa, Power FM 98.7, and MTN Business South Africa.Would you like to use this article in your publication or on your website?

The heat is conducted from the shingles to the sheathingThe part we’re concerned with here is the sunlight that’s absorbed by your roof. Once the roof sucks up those rays, it gets hot. That heat at the absorbing surface (shingles on most residential roofs) then does what the Second Law of Thermodynamics tells it to do — it looks for cooler places, so it starts conducting down through the roofing materials. When it finds the underside of the roof deck, it then can radiate down into the attic. Typical roof decking materials — plywood and oriented-strand board (OSB) – are pretty good radiators, so everything they “see” in the attic starts getting hot, too.You can see the heat transfer I just described in the diagram labeled Figure 1 below. Here’s the basic process:Radiation hits the roof.The radiant energy is absorbed by the roofing materials.The thermal energy conducts downward.Heat radiates from the roof deck to everthing in the attic. The heat radiates into the attic from the underside of the sheathingSo, the dominant form of heat gain in an attic is from radiation, which heats up all the solid materials it finds — framing, ductwork, insulation, all those boxes of Christmas decorations, and dead squirrels. That’s one reason powered attic ventilators aren’t a good solution. They’re going after the air, but the air is hot only because all the solid materials are hot.A better way to reduce the attic temperature is to go after the source — the radiation constantly blasting the attic from the bottom of the roof deck and rafters. Plywood and OSB are good radiators. In physics language, they have high emissivity, which means they’re good at emitting radiant energy.That’s where radiant barriers come in. These are materials that have a low emissivity. When the underside of the roof deck has a radiant barrier installed, the heat still travels through the materials, but once it hits the radiant barrier, it’s come to a dead end. Little of that heat then radiates to the attic.The radiant barrier gets hot. If you go up into the attic and touch it, you’ll see that the heat’s still getting there. But like that stainless-steel playground slide shown at the top of this article, when you hold your hand near it without touching, it doesn’t feel like it’s hot. The magic of low emissivity! Today just feels like a good day to talk about shiny stuff. Radiant barriers are a green building product with a lot of sex appeal, if that’s possible for construction products. People get really crazy about attics, though. (Don’t get me started about powered attic ventilators!) Maybe brains have a tendency to overheat when discussing them. The general category of radiant barriers is an area of great hype and misunderstanding, so I’ll tell you what I know, explain the basic physics, and give you a couple of links to some great resources for more information.OK, first of all, a radiant barrier is something that can keep your attic cooler. Unlike powered attic ventilators, they actually go after the source of the problem rather than treating a symptom — but first, let’s look at the physics.Attics get hot because the sun is beating down on them all day. The heat from the sun comes in the form of electromagnetic radiation. When this radiation hits a surface, it can do one of three things: It can be (i) reflected, (ii) transmitted, or (iii) absorbed. How much of each you get depends on the wavelength of the radiation and the properties of the material it hits. Radiant barriers need an air gapIn case you’re wondering, the answer is yes, this is the same thing that makes low-e windows so good. Also, if you’re wondering how hot the shingles get, the Florida Solar Energy Center has done research on that, which I wrote about a while back.OK, so if the radiant barrier doesn’t feel hot when you hold your hand an inch away but it can burn you when you touch it, what does that mean for installation? You got it! You have to have an air gap next to the radiant barrier. If you spray foam insulation right on the radiant barrier, you’ve wasted your money on the radiant barrier. Heat will conduct right through the radiant barrier because generally, materials with low emissivity have high conductivity. More resourcesThere’s so much more to say about radiant barriers, but let me wrap up this article and give you a couple of resources where you can read more about how they work, how to install them, how much they might save, and why you probably don’t want to install one in Pennsylvania or other cold-climate locations. The first is the Florida Solar Energy Center (FSEC). They have a bit of radiant heat gain in attics down there and know a thing or two about this topic. Here’s a good Question and Answer Primer that’s got a lot of good info.Oak Ridge National Laboratory, which does a lot of great building science research, has several good pages about radiant barriers, too.Another great study is the Houston Home Energy Efficiency Study (pdf). This was a study done by Michael Blasnik and Advanced Energy, and among other things, they looked at the cost-effectiveness of radiant barriers. What they found was that in Houston, Texas, radiant barriers reduced the cooling consumption by about 3%. The paper is well worth the read, in case you don’t already have a copy. (Oh, yeah…it’s free!)Finally, here are a couple of good resources that address the question of if or when you should install a radiant barrier. Martin Holladay wrote Radiant Barriers: A Solution in Search of a Problem a couple of years ago here at Green Building Advisor and included a lot of great info on the topic. Also, a new website called Radiant Barrier Truth tackles the issue of radiant barriers in cold climates.I’ll come back to this topic and write more another time, but for now, let’s not forget what my friend Mike Barcik says is one of the most appealing features of radiant barriers: People like shiny stuff!
