CSIR’s ‘excellent’ year

first_imgThe CSIR has successfully developed afingerprint recognition platform that canperform one-to-one verification (where alive fingerprint is matched to a fingerprintstored in some device) and one-to-manyverification (where a live fingerprint isverified against multiple fingerprintsstored in a database). The ‘Digital Doorway in a suitcase’ wasdeveloped for humanitarian organisationUnicef. It will act as a content server andcommunication hub in disaster areas.(Images: CSIR)MEDIA CONTACTSCSIR• General communication [email protected]• Media enquiriesLehlohonolo Mokhema+27 12 [email protected]• General science communication andCSIR publicationsCollette Vosloo+27 12 [email protected] AlexanderA rabies treatment produced in tobacco leaves, bioceramic material for bone replacement, biodiesel made from algae and a robust portable ICT hub for post-disaster situations: these were just some the innovations produced by South Africa’s Council for Scientific and Industrial Research (CSIR) in the past year.According to the CSIR’s annual report, released on Monday, the organisation has successfully managed to exceed all its targets in areas such as patents granted, royalty income, number of PhD degrees and publications.Download the report (PDF, 7.4 MB)In the report, CSIR CEO Sibusiso Sibisi describes it as “a record of excellent achievement”.“Achieving such positive outcomes across all domains is a reflection of the healthy balance that exists between good science and good business at the CSIR.”Established by the government in 1945, the CSIR is one of the largest science and technology research and development bodies in Africa. While its shareholder is South Africa’s Parliament and it still receives government funding, since 2005 the organisation has been restructured along business lines.Today much of the CSIR’s income is derived from research contracts, royalties, licences, and dividends from companies it has set up to produce and market its innovations.Sibisi says highlights of the past year include the CSIR being granted 35 new international patents, more than doubling its target of 15. The number of science and technology staff with PhDs increased to 273, exceeding the target of 240, and the number of permanent staff studying towards PhDs rose from 90 to 201.The CSIR’s research output for the year included 277 journal articles, 621 conference papers and presentations, 14 books and 38 book chapters.Income from royalties rose 130%, from R9.1-million (US$1.2-million) in 2007/8 to R21-million ($2.8-million) in 2008/9.Research highlightsThe CSIR’s work covers a range of science and technology areas, from health to the built environment, natural environment, energy, defence and security and industry. Some of the highlights of the year include:• Tobacco leaves that produce a powerful post-exposure treatment for rabies.• Working with traditional healers, the capture of 250 claims for cures based on medicinal plants. At least 72 were show to be effective against conditions such as asthma, arthritis and malaria.• A bioceramic material for bone replacement that will do away with the need to harvest the bone from elsewhere in the patient’s body.• Investigating the production of biodiesel from indigenous South African algae.• An ultra-thin (5cm) continuously reinforced concrete for roads. With a lifespan of 30 to 40 years, these roads would be particularly suited to rural areas.• An innovative, modular design for low-cost housing, which could be easily extended by its occupants. A number of components in the house are to be patented.• A mobile, robust and portable information and communication technology hub produced for Unicef for use in coordinating relief efforts after disasters.• A fingerprint recognition system that will relieve South Africa’s dependence on imported biometric products.• A barrier technology for packaging that extends the life of foodstuffs up to 125 times.last_img read more

Lingering issues from 2019 — some thoughts for 2020

first_imgShare Facebook Twitter Google + LinkedIn Pinterest By Harold Watters, CCA, Ohio State University ExtensionI’m not sure what we could have done for the crop this year. I read again today how we planted one day in April, one day in May and finally in early June we had a window only to be hit again with big rains — and then we had to replant in late June. We know that crop production is about collecting sunshine and putting that together with a crop to make sugars — C6H12O6 — that the plant converts to starches, oils and protein. But when we do that with a late June planting, we have cut off 45 to 60 days of potential. Water in mid- to late-season can help overcome the delay, but only a bit.For soybean variety selection, I comb the data. I often make a seed payment early, and sometimes commit to a particular variety, but I prefer to wait for university results to get a comparison across company offerings. I will also be looking hard for frogeye leaf spot resistance. I saw this disease everywhere this year, not a lot of yield impact, but the potential was there. Hybrid selectionI’ve hit on it already about how I like data. I WILL check company and university trial results very carefully this year. Yield works for me but I am willing to give up a bit for better disease protection. Corn fell down last year. I want better stalks in case we have an extended harvest in 2020. Waterhemp. Management. Is not. Happening.This weed got everywhere this year, including in fields that had Extend signs. I study weed resistance and this one appears to be in about year four of the buildup to full blown resistance. I can control it in corn with a good pre-emergent herbicide and a dicamba post application. But I know that overusing dicamba will find those resistance genes in there sooner rather than later, so I use LibertyLink in soybeans. And from Mark Loux, remember his bumper sticker, “Leave no pigweed behind” because the plant/seed you run through the combine will be out there to germinate next year, and the next too. Disease protectionWe have to put scouting back in our vocabulary and in our methods. Choose resistant hybrids and varieties and then check on them for disease. With commodity prices I see right now, I want to save money not spend it. Know what your corn and soybean (and wheat) diseases look like and check for them at the appropriate time. If no disease is present, then don’t spray and know the economic thresholds.Sudden death syndrome appeared late and less than expected, but check for SCN anyway. There are some free sampling kits out there. Really sampling at soybean harvest and getting a feel for your SCN numbers is about maintenance — you really ought to sample all of your soybean fields regularly. And here too, variety selection can help with both of these problems and so can crop rotation. Gray leaf spotIt was spotty, definitely hybrid specific. For me, the surprise was Northern corn leaf blight; even Common rust showed up in several places. I think we need to look a little harder for those good high-yielding hybrids that will tolerate disease and even gripe a little to the seed company agronomists and plant breeders when you see them. Things can get better but pressure must be applied. That’s how biological systems make change. Nutrient applicationsI am looking for free manure. The nutrients are the same and likely bring along some nitrogen with P, K, and sulfur for my crop. The next concern in the absence of manure is potassium. In some areas where we saw dry periods this year, I saw K deficiencies. We don’t want to run too close to our critical level on K. Phosphorus however, I can run a while in areas where I sit in the maintenance range or a little below.And then there’s nitrogen, which was a big concern in 2019. I think I was a bit short early on, and before sidedress application. In my field research work, if I had 50 units of N then those plots recovered more quickly after each deluge. So personally I’ll up my at-plant N, and make sure I have 50 pounds of N through the planter. As to total rate, I want to move to a variable rate application, but don’t own my own applicator — I’m too small. The easiest way for me to get variable rate is by urea broadcast, and that has issues too so I will probably use the Corn Nitrogen Rate Calculator again this next year and put on the right economic rate for the price.last_img read more

Shift to solar energy helps NF Railway cut power expenditure

first_imgThe sun has helped the Northeast Frontier Railway (NFR) save big on energy without having to spend on installation of solar panels. The shift to solar energy at railway stations, level crossings, barracks and other set-ups has coincided with the NFR’s push for electrification of 6,242 km of tracks till the farthest points such as Murkongselek near Assam’s border with Arunachal Pradesh and Sabroom on the Tripura-Bangladesh border.The NFR had during the 2018-19 fiscal commissioned solar panels generating a peak 2,298 KW energy that helped it consume 23.07 lakh units less of electricity leading to a saving of ₹1.88 crore.“This was after paying two executing agencies — one from New Delhi and the other from Hyderabad — for the solar energy at rates fixed by them. It has been a win-win deal for the NFR and the agencies which set up the solar panels and off-grid solar plants free of cost. The assets will be ours after 25 years during which the agencies will recover their costs,” NFR spokesperson Pranav Jyoti Sharma said.Some major railway stations including Guwahati and Dibrugarh have become fully solar-powered while others are in the process of transformation. The ongoing projects cover a few workshops of the NFR.Mr. Sharma said 1,140 KW of solar power was under installation for a targeted saving of ₹98.03 lakh. By March, the NFR hopes to add 2,935 KW to save another ₹1.71 crore. The railway zone has also been exploring the possibility of harnessing wind energy in its hill sections.The NFR has completed electrification of 534 km of broad gauge tracks primarily in the Katihar (Bihar) division. The zone expects to electrify 2,631 km more by March.last_img read more
