You can’t brush off Jimmy Garoppolo’s horrible preseason debut

first_imgPreseason games mean nothing.Nothing for the team, that is. The scores don’t matter and there’s no trophy for having the best record when the four-game slate is over.But make no mistake about it: for individual players in this, the ultimate team sport, preseason performances still matter.And Jimmy Garoppolo and the 49ers’ first-string offense turned in an epic dud on Monday. In the days to come, people will be keen to tell you that Garoppolo’s 1-of-6, one-interception, zero-yard, …last_img

South African entrepreneurs talk about making eco-friendly products

first_imgSeveral small business owners made a conscious decision to produce non-toxic and biodegradable products. Here’s their why.Khululekani Nyobole is an entrepreneur helping to save the planet through his business. “We want to make eco-friendly products accessible to every household in South Africa. It is not just a trend; it is a movement of nurturers – nurturing ourselves, our loved ones and the planet.” (Image supplied)Melissa JavanHer passion for the environment and making a conscious decision that she would do anything so her children could see wildlife and nature, led to her company manufacturing eco-friendly cleaning products, said Blendwell Chemicals‘ Judy Sunasky.Blendwell Chemicals’ head office is in Midrand, Johannesburg. The company makes three ranges of cleaning products, including Enviroblend, which is plant-based and readily biodegradable.“I am passionate about the environment, nature and being outdoors.“I want a future that is bright for my children. I want them to see an Earth where there is wildlife and we are able to feel grass under our feet and sunshine on our faces,” she said, explaining her motivation to make eco-friendly cleaners. It underlines her adherence to the saying, “Be the change you want to see in the world.”Judy Sunasky of Blendwell Chemicals says her company started producing eco-friendly product in 2011. “Enviroblend is the green, eco-friendly certified range. These products are innovative, sourced from sustainable plant-based chemicals and are non-toxic and readily biodegradable.” (Image supplied)Sunasky is not the only one with this sentiment. Khululekani Nyobole of Nurturer and Raj Lalloo of OptimusBio also make environmentally friendly products.Their products are sold through distribution agents and their websites.Collective responsibilityWriting on Bizcommunity.com, Justin Smith said South African companies, including those in the retail sector, continued to experience a significant change in customers’ mindset.“The reality is that doing business is no longer just about profit, but also about creating shared value and meeting responsibilities to contribute to inclusive economic development, and to give back to communities and our planet.”Smith is head of the Woolworths Good Business Journey, the retail chain’s sustainability programme. He wrote that we were seeing things such as changing weather patterns in South Africa and increased frequency of climate-related disasters.These issues, along with other agricultural concerns, plus water scarcity, affected food security and food prices, which ultimately put pressure on South African consumers.“It is our collective responsibility as corporate citizens to look to reduce resource consumption patterns, both in our respective places of business and along our supply chains, to see where efficiencies can be enhanced.”Woolworths is an example of a company doing things differently in support of the environment. It replaced all the plastic microbeads in its label beauty and personal care products with biodegradable alternatives, reported Bizcommunity.com.Microbeads are tiny, non-biodegradable plastic spheres that are widely used in face and body scrubs to deliver the exfoliating action. Because of the microbeads’ size, they clog sewerage systems, water courses and oceans, endangering marine and aquatic life.Woolworths replaced the microbeads with natural and biodegradable ingredients such as jojoba oil beads, apricot kernels and synthetic wax beads.NurturerEntrepreneur Khululekani Nyobole was born and raised in the Cape Town township of Khayelitsha. “This (area) is where the majority of the people work for survival – to get their basic needs met,” he said.According to News24, Nyobole matriculated from Crystal Secondary School in Hanover Park, after failing Grade 10 three times. “I’d always wanted to start my own business. I wanted a qualification. I wanted stability. That’s when I decided to start Nurturer because the environment is close to my heart.”Nurturer makes affordable, environmentally friendly cleaning products. They went to market in February 2017.Eco-friendly products found on shop shelves were not only inaccessible as they are available in the more affluent areas, but they were high-end products that were sold at a premium, Nyobole said.“Even if they would care for the environment, their financial state does not allow them to buy better products,” he explained about his community.“This bothered me because eco-friendly products are part of the solution to the crisis of environmental degradation and to our healthcare. Their purpose cannot be fulfilled in Africa if they are only used by the minority or the elite. This is the fundamental reason why we (Nurturer) exist,” Nyobole said.His company developed a direct selling model so that a “nurturer” could talk to consumers one-on-one. “We aim to create awareness by sharing information about toxins that are lingering in their homes from the products they use and the consequences of using such products such as poor indoor air quality and skin/eye irritations.“We then share the benefits of switching to eco-friendly products and exhibit this through demonstrations.”OptimusBioRaj Lalloo, OptimusBio chief researcher and chief technical officer, said the company was a spin-out from the Council for Scientific and Industrial Research (CSIR) that produces next-generation biotechnology products for green cleaning, sanitation, water and waste treatment.Founded in September 2014, the company is in Pretoria. OptimusBio makes products for domestic and institutional cleaning, rural sanitation, water treatment, industrial waste treatment, agriculture and aquaculture.It uses technology developed at the CSIR’s Biomanufacturing Industry Development Centre. Lalloo explained: “The technology is based on the concept of biomimicry, which is when good bacteria are used as nature’s ‘machines’ to clean wastes.“Our indigenous bacteria integrate into natural ecosystems through the principle of bio-augmentation. The products were developed with the aim of replacing the harsh chemicals and pollutants with next-generation biological and biodegradable alternatives, to improve wellbeing, while preserving scarce water and environmental resources.“This is a highly impactful offering from CSIR technology, developed over many years, and we are excited about how it will change the landscape towards a more sustainable planet.”For example, the products helped with rural sanitation, pit latrine toilets and septic tanks by biologically degrading waste, he said. “This assists with quality of life, odour, disease and flies.”PhepisaPhepsile Maseko founded Phepisa Natural Resources Institute in Johannesburg in 2010. Phepisa focuses on developing and distributing safe, traditional and natural innovative treatments that help people lead a healthier life.They include the Gwenge range of skincare products. All of the items in the range have a South African plant extract as the main ingredient.Maseko, who is a traditional healer, says on her website that she grew up having a recurring dream that later became a vision. The dream involved a bunch of rich, green, medicinal plants shaped like a carrot.“I was later to learn that it was a sign from the ancestors that I was the chosen one to be taught about ancient healing methods and secrets that have been passed down in my family for over three generations.”Maseko’s father taught her where to find and identify the different herbs and plants for medicine. “He would then teach me how he makes formulations for different ailments from these plants. This was an exciting world for a young girl; it was also my schooling in African traditional medicines and healing practices.”Would you like to use this article in your publication or on your website?

Higher carbon dioxide levels prompt more plant growth, but fewer nutrients

first_imgShare Facebook Twitter Google + LinkedIn Pinterest It might seem there’s an upside to the rising levels of carbon dioxide in the atmosphere. Plants are growing faster.However, in many species of plants, quantity is not quality. Most plants are growing faster, but they have on average more starch, less protein and fewer key vitamins in them, said James Metzger, a professor and chair of the Department of Horticulture and Crop Science in The Ohio State University’s College of Food, Agricultural, and Environmental Sciences (CFAES).This change is happening because the current level of carbon dioxide in the atmosphere is 400 parts per million, nearly double what it was in the middle of the 18th century, the start of the industrial revolution. And it keeps rising, spurred by the burning of fuels.Taking in carbon dioxide and light, a plant forms sugars and starches first, then other nutrients including protein, fat and antioxidants. Though carbon dioxide is necessary for plants to live, too much carbon dioxide can reduce the amount of valuable nutrients the plant produces including iron, zinc and vitamin C.“The loss of nutrients, particularly protein, is serious,” Metzger said. “That does not help in the effort for people to eat more balanced diets and increase their nutrition.”Animal meat and dairy products are a significant source of protein for humans. So, if animals aren’t getting sufficient protein from plants, that will affect what they can produce as food.What’s happening is that a higher level of carbon dioxide in the atmosphere reduces the amount of photorespiration that occurs in plants. During photorespiration, plants take in oxygen from the environment, release carbon dioxide and produce waste products including glycolic acid, which a plant can’t use. In order for the plant to turn the glycolic acid into a product it can use, the plant has to do more photosynthesis, the process through which plants use sunlight, water and carbon dioxide to create glucose, a form of sugar that plants need to survive.Low rates of photorespiration, caused by the higher amounts of carbon dioxide, are associated with low stress levels in plants, which ironically is not a good thing. That’s because stressed plants respond by producing antioxidants such as vitamins C and E, as well as higher protein levels. So, as carbon dioxide levels in the atmosphere rise, there is less photorespiration and therefore less stress on plants. And the reduced stress means increased growth, but at a cost, a decline in the nutritional quality of the plants.“This has been observed in many different species of plants,” Metzger said.If the plant is not producing enough antioxidants, that’s not just less healthy for people who later eat the plant, but also for the plant’s ability to fend off diseases, Metzger said. Plants can become more vulnerable to diseases as well as insects. With fewer nutrients in the plants, the insects have to devour more of them to get the same nutritional value.Not all plants react to the rising carbon dioxide levels in the same way. Some crops, including corn and sugar cane, do not decrease in nutritional value in the midst of higher carbon dioxide levels. That’s because their photosynthesis process differs from that of most other plants.Temperature is a factor as well. Depending on the temperature, plants can react in different ways to high carbon dioxide levels. The rising carbon dioxide levels that are triggering more photosynthesis can hinder the growth of some plants cultivated in temperatures below 59 degrees Fahrenheit, such as winter wheat, said Katrina Cornish, Ohio Research Scholar and Endowed Chair in Bio-based Emergent Materials with CFAES.Plants grown in hot weather conditions can also be impeded by elevated carbon dioxide. In hot temperatures, many plants stay cool by opening wide the pores on the underside of their leaves. But in an atmosphere with high carbon dioxide, the pores do not open as wide, so plants are not able to keep themselves cool, Cornish said. This could cause “the plants to become crispy critters and die, when they were OK at lower carbon dioxide levels,” she said.“Plants need time to adapt to the increase in carbon dioxide levels. And the increase is happening so quickly, plants are not going to have a chance to adapt.”In the short term, the additional photosynthesis spurred by higher carbon dioxide levels may bring about small gains in the amount of leaves, stem and shoots that are produced by a crop but not necessarily in the portion of the crop that can be harvested. And in the long term, it’s going to do more harm to plants than good, Cornish said.“There’s going to be a tipping point, and that tipping point is different for each crop,” Cornish said.Already, rice plants grown in elevated carbon dioxide have been shown to produce more tillers, which include the stems and leaves of the plant, but fewer and smaller grains.One way to prevent the higher carbon dioxide levels from affecting plant growth and yield is through plant crossbreeding and gene manipulation, Metzger pointed out. Both could lead to the creation of varieties of plants whose growth and nutrient levels will be less affected by the higher amounts of carbon dioxide in the environment.More research is needed to figure out how a plant produces antioxidants, Metzger said.“I think it’s important that we put some effort into really understanding how those biochemical pathways are controlled and how we can manipulate them without any harmful effects on the plant.”last_img read more

Apple’s iOS 6 Maps App Falls Short In Early Reviews

first_imgTop Reasons to Go With Managed WordPress Hosting Why Tech Companies Need Simpler Terms of Servic… Another widely cited issue with Maps is that it’s not as comprehensive as Google’s offering. As Stevens explains, “Maps will list some important POIs – mostly gas stations and convenience shops – but if you want to see all Mexican restaurants on your route you’ll have to dig deeper.”In his lengthy iPhone 5 review for AllThingsD, Walt Mossberg says Maps is the “biggest drawback” he experienced while test-driving the new iPhone, citing the lack of transit directions and the loss of Google’s photographic imagery. Granted, this is a software feature (and thus easier to address than a cruddy camera or underperforming processor), but Maps is used very heavily by many users, so its substandard performance affects a broad swath of the iPhone community. Even the typically Apple-friendly MG Siegler wrote that, while he was impressed by Maps overall, it’s still not as good as Google’s app. Most critics of the new app have been understanding, given the complexity of providing a mapping solution, Apple’s business need for booting Google and the fact that it’s a brand new program with many iterations down the road. Anil Dash was less forgiving. Calling the Maps upgrade “pretty but dumb,” Dash called Apple out for replacing a widely-used feature with something less polished and comprehensive. Having used iOS 6 for a few months, Dash put the app through its paces and found that the traffic directions and venue search capabilities fell short. Apple clearly has improvements to make in Maps, but it does look like a fairly solid offering overall. The lack of transit directions is unfortunate for any city dweller, but third-party apps are often better than what Google provided. In my own testing, I found the UI of Maps to be hugely improved, especially the way that driving directions are displayed. It’s not only nicer to look at, but it’s also probably safer for drivers to use, particularly when combined with the iPhone’s hands-free, turn-by-turn navigation.It may not seem like a worthy successor to Google Maps, but it’s viable and presumably Apple is working on improvements. And who knows? Perhaps Google is working on its own Maps app for iPhone, just as it did with YouTube. If paying customers are as dissatisfied as some of the early reviewers, it wouldn’t be surprising for Google to capitalize on their discontent.        Tags:#Apple#web Related Posts Most people wont’ get their hands on an iPhone 5 until later this week, but the early reviews are in. Most critics are enamored with Apple’s latest smartphone: It’s faster, thinner, taller and, even though the camera isn’t a huge upgrade, it’s still an improvement. But one new feature isn’t getting much love: the native mapping application in iOS 6.Apple made headlines earlier this year when it was confirmed that Google Maps would no longer be the default app for mapping and navigation on iOS devices. That years-old partnership crumbled amid rising tensions between the two companies, mostly due to Google’s entry into the smartphone market. To fill in the gap, Apple acquired C3 Technologies, a company that specialized in building 3D mapping software. At its Worldwide Developers Conference last summer, Apple showed off the slick, immersive result. While many agree that the user interface of Apple’s Maps is an improvement over its predecessor, not everyone is thrilled with the overall experience. Writes Tim Stevens on Engadget: The biggest drawback is the unfortunate lack of public transportation directions. If you haven’t quite mastered New York City’s subway system, you won’t get any help from your iPhone 5. Curiously, the app offers to give you public transportation directions, but should you choose that option it pops you straight into the App Store with a search for “Routing Apps.” Right now, there are zero results.That’s odd. We figured Apple would partner with third-party transit app developers and at least link directly to those providers. (The lack of search results sounds like a glitch Apple will soon fix.) That would be a big win for those developers and would help keep the user experience intact.  john paul titlow 8 Best WordPress Hosting Solutions on the Market A Web Developer’s New Best Friend is the AI Wai…last_img read more

Why You Absolutely Must Read Books

first_imgEvery human being that is born starts at exactly the same place. They are a blank slate, knowing nothing that they need to know to survive and thrive in the world in which they find themselves. There is no knowledge that is transferred biologically from parents to child. Regardless of the capacity to learn and the different forms of intelligence human beings possess in greater or lesser quantities, you have none of it.Even though you know nothing at birth, much is already known by others. The people that have come before you have had experiences that resulted in a certain knowledge in that area. Other people have studied some area to make discoveries and develop a deeper understanding of this thing or that. When you are born, you are way behind in the acquisition of human knowledge, some gained through experiences and some through research and study.If you embrace the idea that books are not helpful to learning you are deciding that there is nothing worth knowing if it is not gained through your own experience. This is to suggest that the way one should learn about the dangers of fire is to burn themselves, even when others who have already had that experience might strongly suggest that you don’t burn yourself, and even if they can explain to you very clearly and easily how not to do so.Let’s use K. Anders Ericcson’s 10,000 hours rule, popularized by Malcolm Gladwell. Through a lifetime of experience, someone has learned something useful to other people. While doing so, they have also developed the concepts and ideas that help other people make sense of this thing they know. They have also developed some advice, some strategies, and some tactics that might help other people produce results in this area both faster and more effectively, and they’ve codified these ideas in a common form that allows the transfer of this knowledge from one person to another.The suggestion that one would be better off avoiding any knowledge that wasn’t gained through own their experience is to believe that there is nothing that can be known that would shorten the learning curve. Following this thinking, you would have to learn that multiplication and division are concepts on your own. It would mean that the only history of any value is your own and that your analysis of your experience is the only experience with any real value. The collective whole of human knowledge and experience would be of no value to you at all, being full of ideas, concepts, strategies, tactics, and instructions that, despite being useful to thousands or millions of people before you, are worthless.It is true that you cannot learn to swim by reading a book. But you can shorten the learning curve and accelerate your mastery by learning from those who already swim at a level far beyond the level of competency you’ve achieved. Part of that learning can and will be codified in the form of a book. Reading helps you understand your experience and provides context.For around $25 and 6 hours of your time, you can learn what took someone else a lifetime to learn.Any suggestion that you should not read books should be rejected with extreme prejudice, and you should think carefully about taking any advice from people who believe there is nothing to learn from others if it has been published as a book. There is no reason to remain ignorant when help gaining knowledge and understanding is available to you, and for a song at that. Essential Reading!
