Ash trees are often found in open, sunny sites and are most susceptible to a bug attack, especially newly transplanted trees, as the insects prefer feeding on young tissue. When attacked, the leaves appear distorted, burned and stippled at an obvious premature time frame. The threat of egg-laying punctures may also result in diseases entering the plant.There are two methods of control; organic and chemical. The organic method requires a vigorous growing condition, supplying adequate moisture and fertilizer, helping the tree withstand damage. Although, adult bugs are often found returning to the tree.- Advertisement -There’s also the chemical method which requires the use of insecticides. First application is recommended in mid-May when the leaves are expanding; however it’s only necessary when insects are visible or when damages first appear. Insecticidal soaps and Pyrellin are most accepted among organic growers, and while large trees are difficult to spray, they’re less likely to require treatment.If treatment is necessary, consider consulting a professional tree care service for assistance.
0Shares0000Raja’s players celebrate victory © AFP / KARIM JAAFARDOHA, Qatar, Mar 29 – Raja Casablanca of Morocco deservedly won the African Super Cup on Friday, narrowly beating Tunisia’s Esperance 2-1 to lift the trophy for the second time.Goals from Abdelilah Hafidi, a superb first half strike from 20 yards, and a neat close-range finish from captain Badr Benoun in the 65th minute sealed victory for Raja. Those goals came either side of a wonderful equaliser from Esperance’s Mohamed Youcef who smashed home an unstoppable shot in the 57th minute to give the Tunisian side brief hope.But they could not come back a second time and there were delirious scenes at the end as Raja’s players celebrated their first Super Cup trophy in 19 years.The Super Cup is an annual one-off match pitting the winner of the CAF Champions League and second-tier CAF Confederation Cup against each other.Friday’s match was played in 2022 World Cup host nation, Qatar, the first time it has been played outside Africa.It attracted a near capacity crowd of 18,378.The victory was some consolation Raja’s French coach Patrice Carteron.He was the manager of the Egyptian team, Al Ahly, who lost to Esperance in the Champions League final last November, which led to him being sacked.“I am very happy, I am very proud to bring this title to Casablanca,” he said.There was little chance of him ending up on the losing side again on Friday as his team dominated for long stretches of the final.Mahmoud Benhalib, and Soufiane Rahimi went close in the first half before Hafidi’s fine finish in the 22nd minute.Rahimi also spurned a chance just six minutes later to double Raja’s advantage.Esperance — described as the best team in Africa by Carteron before the match — took until 36 minutes to threaten Raja’s goal, but should have equalised with their first opportunity when Taha Yassine Khnissi spurned an easy chance while through on the goalkeeper.The Tunisians did draw level early in the second half though through Youcef and at that stage appeared the most likely to win.But Raja quickly reasserted their dominance when Benoun flicked in a winner from close range following a corner.Raja could have also had a penalty in the closing stages after an apparent handball was missed by the referee and Rahimi also had a goal ruled out for offside in the 75th minute.Carteron said he hoped the victory would “motivate the team for the rest of the season”, as they seek to qualify for next year’s Champions League.A downcast Moine Chaabani, coach of Esperance, congratulated his rival and added: “It’s a disappointment for us.“We had an eye on the title, we had hopes. For me we put in a more than average game.”0Shares0000(Visited 1 times, 1 visits today)
CRIME: Mom, who was living in a shelter, is charged with abuse. By The Associated Press A homeless mother whose 7-week-old baby died of starvation, dehydration and neglect at a Skid Row shelter was charged Tuesday with child abuse. The felony complaint seeks Ranetta Marie Maxwell’s arrest in connection with the Aug. 10 death of her daughter Jasmine, who spent her brief life with her mother at downtown L.A.’s Union Rescue Mission. The Department of Children and Family Services, meanwhile, is investigating whether a social worker who was handling the baby’s case did enough to keep her safe and get appropriate medical attention, said Patricia Ploehn, the agency’s director. The worker was directed to take Jasmine from her mother to see a doctor, but went home instead after working a long shift without a break. She had checked Jasmine during an emergency visit early on Aug. 9 and reported the baby’s face was “narrow and skinny,” according to county records obtained by the Los Angeles Times. The worker made an appointment for the infant at a nearby clinic but learned later that day Maxwell hadn’t kept the appointment. When her supervisor told her to take the baby to a clinic that night and approved her overtime pay, the social worker decided to wait. She left a message in her department’s computer system that she was unable to go because she had already worked “11 hours without a break” and thought she could take the baby the next day, the Times reported. Jasmine, who was born June 24 at 6 pounds, dropped to 4 pounds before she died.160Want local news?Sign up for the Localist and stay informed Something went wrong.

(Image: Botswana University)Janine ErasmusFind out more about using MediaClubSouthAfrica.com materialConstruction on the long-awaited Botswana International University of Science and Technology has begun. Hopes are high that the institution, when complete, will be the educational pride of the country and eliminate the need for Batswana youth to leave the country to study elsewhere.The project arose out of a 2005 United Nations Development Programme report, which called for more funding for science in Botswana.The report, titled Harnessing Science and Technology for Human Development, found that Botswana was under-performing in the disciplines of science and technology, despite having all the equipment to conduct significant research.The report also recommended that the country develop its own postgraduate programmes instead of sending its brightest thinkers overseas to study, thereby running the risk that they will not return.Finally, the report acknowledged the severe toll that HIV and Aids has taken on the country, and recommended that Botswana protect itself against future epidemics by developing a core of expertise in health-related research and development, especially with regard to HIV and Aids.The government of Botswana approved plans for the new facility a year after the report’s publication. It is the second university in the country, but will not duplicate courses offered by the University of Botswana. Instead, relevant courses will be moved to the science university.Early delaysThe project has experienced a number of logistical delays. Early in 2008 there were electricity problems with South African parastatal Eskom, which supplies most of Botswana’s power. Eskom struggled to meet local demand at the time and was forced to cut down drastically on electricity exports.Minister of Education and Skills Development, Jacob Nkate, also admitted that government had underestimated the scope of the project and had set an unrealistic date for completion. However, with construction now underway, the mood has changed to one of optimism.The project is expected to create many jobs and put a stop to the importation of skilled personnel into top positions. It will thereby contribute to poverty alleviation, and boost regional economy.“We have to develop a high quality university that we can market with pride to the whole of Africa,” said Nkate.Sacred groundThe new institution is situated in Palapye in the east of the country, about halfway between Francistown and Gaborone.The 2 500ha of land on which it stands, according to Palapye headman Kgosi Raditanka Ntebele, is part of the Tswapong region, currently on the tentative list for inscription as a world heritage site. This holy ground is protected by the ancestors, he said, who make it impossible for anybody to climb the ancient Tswapong hills at night without angering them.Government has averted any such potential incidents by consulting closely with the people of the area, a step lauded by Ntebele.The chief was particularly impressed with the sensitivity and professionalism displayed by government officials who exhumed burial sites. The remains of 15 Batswana were reverently moved to Palapye’s Mmaphula cemetery.No stranger to AfricaThe state-owned China Civil Engineering Construction Corporation, based in Beijing, has won the contract for phase one.The company is involved in a number of domestic and international projects and is no stranger to Africa, having already worked on the renewal of roads, railways and other infrastructure in Uganda, Botswana, Nigeria, Zambia and Tanzania, and stadiums in Rwanda and Djibouti.Stage one, worth US$61.5-million (R495.6-million), is funded by the government of Botswana and is proceeding without a private partner. Spanning two years, this phase includes the construction of the administration block, halls of residence for nearly 300 students and houses for 70 staff, laboratories, auditoriums, a student centre and book shop, a clinic, and classrooms.The new university’s vice-chancellor, Ghanaian civil engineer Kweku Bentil, speaking to the Gaborone Rotary Club in February 2009, revealed that the second stage will see a private partner coming on board. This phase involves maintenance and further construction of a research park, among other structures, while the final phase entails the addition of a shopping mall, schools, and a golf course.The first batch of 256 students is expected to walk through the doors in 2011. The university will operate initially with four faculties – Engineering, Technology, Science and Business. Study will focus on engineering, mining, geology and basic sciences.Later student intakes will increase to 3 000 and then to 6 000, with admissions accepted three times a year from all over the continent.Bentil said he hoped the university would attract the finest minds from around the world into teaching and research positions, and produce graduates who are both technologically- and business-savvy, ready to step into any job.The Botswana government spends millions each year to support the thousands of students at universities outside the country, added Bentil. “The science university can help reduce the number of such students and the cost of their training.”Do you have queries or comments about this article?

The SKA host decision makes the mostof the vast amounts of money alreadycommitted to the project by the bidrivals. (Image: Janine Erasmus) MEDIA CONTACTS • Marina Joubert SKA South Africa communications +27 83 409 4254 RELATED ARTICLES • Great astronomy, with or without SKA • Big science coming to SA • Pandor: we did it • SA assists with Nasa’s Mars mission • Gallery: the KAT-7 radio telescopeJanine ErasmusNow that the long wait is over and the co-hosts of the Square Kilometre Array (SKA) have been announced, South Africa and Australia can get on with the business of building the world’s biggest scientific instrument.Although the site is to be shared, the split is not equal – Southern Africa will get the juiciest part of the SKA pie.The technology will be rolled out in two phases. Actual construction of the SKA is expected to start in 2016, with mid-frequency antennae – the big dishes similar to those seen in the KAT-7 grouping, now operational at the local SKA site – and an array of low-frequency antennae making up the first phase.Phase two will commence in 2018 and will continue up to 2023.“Scientists should be able to use phase one for research by 2020,” said Prof Justin Jonas, associate director for science and engineering at SKA South Africa. “By that time construction on phase two should be underway, with full science operations commencing by 2024.”The SKA was always perceived as a two-phase project, said Jonas.“Even if one country had hosted the whole thing, the phases would have been built at a distance from each other,” he added. “Now the phases will just be further apart.”He said the technology differs for each component, and they operate independently.Southern Africa’s core site is deep in the Northern Cape province, sitting at an altitude of 1 000m and located about 100km west of Carnarvon, a sleepy Karoo town. This site is not only quiet in audio terms, but more importantly for the SKA, it’s a radio-quiet area that’s legally protected by the Astronomy Geographic Advantage Act of 2007 to keep it that way.From the core of about 1 500 antennae, another 1 500 or so will radiate out to other parts of South Africa and Southern African countries, some as far out as 3 000km away. The partner countries are Namibia, Botswana, Ghana, Kenya, Madagascar, Mauritius, Mozambique and Zambia.The core site down under, on the other hand, is at Boolardy, a former sheep station about 100km west of the mining town of Meekatharra. This remote town lies about 770km northeast of Perth in Western Australia.This gigantic scientific instrument will have a combined collecting surface of one square kilometre, and will be 50 times more sensitive and 10 000 times faster than anything else yet built.In South Africa, data gathered from all these far-flung receivers will be processed locally. But, said Jonas, computers from all over the world could conceivably work on the data.“So everybody will get something out,” he said.The world’s most sensitive radio telescopeThe KAT-7 is the precursor to the MeerKAT, an array of 64 dishes which in turn will form the beginnings of the SKA. MeerKAT was acknowledged in the SKA site advisory committee’s report as a crucial step in the implementation of the SKA.Australia’s equivalent of MeerKAT is called ASKAP – the Australian SKA Pathfinder, which consists of 34 dishes. Both test sites have used mid-frequency instrumentation to demonstrate their technology.“The MeerKAT will supplement the sensitive SKA phase one dish array, providing a large part of the collection area of the world’s most sensitive radio telescope,” said South Africa’s science and technology minister Naledi Pandor at a briefing to announce the final hosting decision.“We have always said we are ready to host the SKA – and the world has listened.”Pandor has been widely hailed for her leadership throughout the initial and bid processes, which took about nine years to get to the decision-making stage.“She led the team remarkably. She was born for a time such as this,” said mathematician and astrophysicist Prof David Block of Wits University, speaking to Moneyweb.So who gets what?Three different types of antenna technology will be used to cover a wide range of frequencies between 70 megahertz and 10 gigahertz – they are the mid-frequency dishes, and the low- and mid-frequency aperture arrays.The aperture arrays are cost-effective to build and run, and can observe more than one part of the sky at the same time.With each standing about 1.5m high, the low-frequency aperture arrays can be accommodated in a relatively modest area, compared to the bigger 15m-tall dishes. A baseline of 200km would suffice, according to SKA.The South African part of phase one, the whole of which constitutes about 10% of the total SKA, will include the 64 dishes of the MeerKAT, plus another 190 dishes.Across the Indian Ocean, the ASKAP too will be absorbed into phase one. In addition, 60 mid-frequency dishes and an as yet undisclosed number of low-frequency aperture arrays will be installed.In phase two, all the dishes will be built in Southern Africa – this is the stage at which the widely-spaced dishes will start to spread into the partner countries, out to a distance of 3 000km or more from the core. A number of flat, 60m-wide mid-frequency aperture arrays will also be built here – the number will be determined later.The rest of the low-frequency aperture array antennae , as many as 10 times more than in phase one, will be constructed in Australia and New Zealand.“The higher elevation of the South African site is an advantage for the mid-frequency telescope, hence the allocation of this segment of the SKA to South Africa,” said Jonas.It means that South Africa will have the ability to make lengthy, deep observations of a narrow part of the sky, while Australia will be able to more quickly make surveys of wider portions.In terms of costs, he said, members of the SKA organisation – South Africa, the UK, Australia, Canada, China, Italy, New Zealand and the Netherlands – will all contribute to capital and running costs. Depending on whether new members come on board, these costs may vary.A worldwide network of supporting elements, including staff, scientific institutions, data networks and computing facilities is also now needed, said Jonas.The hosts will now enter a design and pre-construction phase before the SKA begins to take physical shape.South Africa will also press on with the MeerKAT which, said Pandor, would have gone ahead whether or not the country had been awarded the SKA.

Start Free Trial Already a member? Log in Let’s say you walk into an unheated room. The air temperature is only 50°F. There is a wood stove in the room, but the wood stove is unlit.Your body is at about 98°F. Since your body is warmer than absolute zero, it is radiating heat in all directions. (All objects that aren’t at absolute zero emit infrared radiation). The wood stove is cool — it’s at 50°F. Still, the wood stove is also radiating heat in all directions.Since you are warmer than the wood stove, you are radiating more heat to the wood stove than the wood stove is radiating to you. If you stand there long enough, the wood stove will get a little warmer, and you will get a little colder.If someone lights a fire in the wood stove, and the temperature of the stove rises to 300°F, what happens? You are still radiating heat to the wood stove. And the wood stove is still radiating heat in your direction. But since radiant heat is flowing at a faster rate from the stove to you than from you to the stove, you are going to end up feeling warmer.The phenomenon I’m describing is explained this way in a document posted on the National Weather Service web site: “Every warm object loses energy by radiating electromagnetic energy (e.g., infrared photons). If it receives an equal amount of energy from other objects, it is in radiative equilibrium; if it receives less from other objects, it loses energy and cools down.”An online article by Mike Luciuk notes, “The outgoing radiated power of [an average human] would be about 1,039 watts. In other words, a human body radiates power close to that of a toaster, with a peak wavelength of about 9.5 µm.… This article is only available to GBA Prime Members Sign up for a free trial and get instant access to this article as well as GBA’s complete library of premium articles and construction details.
