They were arrested as they were putting their equipment back in their vehicle and police seized their camera, film and the vehicle. The cameraman was freed nearly three hours later and the sound engineer the following afternoon. The authorities said they had been arrested because they did not have permission to film inside the university. The material has been restored to the team.

The Americans took home 239 medals, including 78 golds. Germany, the second placed country on the medal table, had 13 medals in all, with third-placed Cuba on nine. The country finished 23rd on the medal table. Once more, the USA was number one, with 22 gold medals and a total of 56 medals in all. Germany finished second and Finland third. Four years later, in London, South Africa won its first Olympic medals, with Reggie Walker winning the prestigious 100 metres gold and Charles Hefferon claiming second place in the marathon. South Africa ended 18th on the medal table. The USA finished first, with 45 gold medals and a total of 99. Finland placed second and France third. The country produced a single champion again. Sydney Atkinson, a silver medallist four years earlier, won the gold medal in the 110m hurdles. The men’s pursuit team, made up of Walker, Smith, Kaltenbrun and Harry Goosen added a bronze medal, and tennis player Charles Winslow, the winner of a gold medal in the men’s singles eight years earlier in Stockholm, took home a bronze medal this time around. In terms of gold medals won, the 1912 Stockholm Games rank as the most successful Olympics in South Africa’s history. The only gold medal came from bantamweight boxer William Smith. Having just turned 20, he was the youngest ever Olympic boxing champion. Four years later, after a 28-year break, the Olympic Games returned to the United States and were hosted by Los Angeles. Despite winning just two medals, South Africa placed 14th on the medal table. Eddie Peirce was South Africa’s third medal winner in boxing, with a bronze medal in the middleweight division. Stockholm 1912 Amsterdam 1928 In 1928 the host city was Amsterdam. South Africa, for the first time competing under the its new flag – consisting of background colours of orange, white and blue, with three smaller flags in the centre, the Union Flag, the flag of the Orange Free State and the Transvaal Vierkleur – once again won only three medals. Boxer Harry Isaacs captured bronze in the bantamweight division, while Rhoda Rennie, Frederica van der Goes, Marie Redford and Kathleen Russell teamed up to finish third in the women’s 4x100m freestyle relay, winning the first ever swimming medal for South Africa, while producing the first ever medal-winning performance from South African women. Clarence Walker won South Africa’s first Olympic boxing gold medal in the bantamweight division. It was the start of a run of success for South African boxers at the Olympics, which led to the sport becoming the country’s most successful medal winner at the Games, apart from athletics. At the top, the USA edged Sweden for the most golds – 25 to 24, but the Swedes captured the most medals – 65 to the USA’s 63. St Louis 1904South Africa first competed in the Olympic Games in St Louis in 1904. Unfortunately, the country failed to win a single medal. That was not really surprising as the squad consisted of only three marathon runners and a tug-of-war team. It was eight years before the Olympic Games were held again because of the First World War. Antwerp in Belgium was the host city. At the age of 19 years and 128 days, Walker remains the youngest 100 metres champion in the history of the Olympics. In terms of total medals won, Antwerp proved to be South Africa’s most successful Games. The 10 medals won stood as a record for the country until it was matched at the 1952 Helsinki Olympics. However, that mark has never been bettered. Sydney Atkinson secured the South African team’s only silver medal in the 110m hurdles, while Cecil McMaster completed the list of South African medal winners with a third place in the 10 kilometre walk. South Africa finished 15th on the medal table in Los Angeles. The best performers were Len Tau, who finished ninth in the marathon, while the tug-of-war team ended fifth. The Games were dominated by the USA, which was not surprising as not more than 60 athletes from outside North America are reported to have taken part in the 1904 Games. It would take until 2004 for another South African to match Rudd’s feat of a medal of every colour at an Olympic Games. London 1908 18 July 2012 Great Britain was far and away the most successful team. Its 56 gold medals was more than the total number of medals claimed by the United States, which finished second in the standings with a total of 47 medals, 23 of which were gold. Rudolph Lewis raced to gold in the road cycling event, and continuing the endurance theme, Ken McArthur took victory in the marathon. Christian Gitsham finished second to McArthur, to add another silver medal to that won by Kitson in the tennis. Bevil Rudd, who had served in the First World War and won the Military Cross for bravery, was the star of the team, winning medals of every colour. He was crowned champion in the 400 metres and helped South Africa to second place in the 4x400m relay. He added a bronze medal in the 800 metres. Paris 1924Paris hosted the Olympics in 1924. They were not nearly as successful for South Africa as the Antwerp Games. The hosts, the USA, dominated. Their 41 gold medals exceeded the total number of medals won by the second placed Italian team, and they tallied 103 medals in all. Italy won 12 gold and 36 medals in all, with France finishing in third place. With four gold and two silver medals, South Africa finished in seventh place on the medal table, the best position ever achieved by the country. The team of David Smith, Robert Brodley, Ferdinand Buchanan, George Harvey and Frederick Morgan also claimed silver in the men’s team 600m military rifle event. It remains the only shooting medal ever won by South Africa. Antwerp 1920 Marjorie Clark became the first South African woman to win an athletics medal after finishing third in the 80m hurdles, while Jenny Maakal claimed bronze in the 400m freestyle, making her the first South African woman to win an individual swimming medal at the Olympic Games. There was another South African gold medal in tennis, with Louis Raymond defeating Ichiya Kumagai, who became Japan first ever Olympic medallist, 5-7, 6-4, 7-5, 6-4 in the final of the men’s singles. With three gold medals, four silvers, and three bronzes, South Africa placed 11th on the medal table. The USA led the way with a total of 95 medals, including 41 golds. Sweden again placed second, with Great Britain in third. Los Angeles 1932 How much do you know about South Africa’s history at the Olympics? When was the country’s best performance? Who are SA’s top Olympians? Check out the records and the trivia in the first of three articles covering the 18 Olympic Games the country has competed in. Two South Africans became Olympic champions. David Carstens continued the country’s success in the boxing ring, lifting the light-heavyweight title after defeating Italian Gino Rossi in the final, while Lawrence Stevens, competing in the lightweight division, defeated Thure Ahlqvist of Sweden to win gold. Tennis player Charles Winslow won gold in the men’s doubles with Harold Kitson. He also beat his doubles partner to win the men’s singles. Cycling produced more success, with Henry Kaltenbrun finishing second in the men’s individual time trial and Wlliam Smith and James Walker ending second in the men’s tandem, an event which was discontinued after the 1972 Munich Olympics. Silver medals went to Bevil Rudd’s relay team-mates Henry Dafel, Clarence Oldfield, and Jack Oosterlaak. Would you like to use this article in your publication or on your website?

This is a really good quality wig. Nice colour, lots of hair, very secure and well-constructed cap so fits snugly on your head and stays put. The hair itself feels nice and somehow not as plasticky as other cheap wigs. Also does not get as static-ky which can be a problem with cheap wigs.

As others have mentioned, bit straggly on the longest hair at the back so trimmed this to make it thicker. I usually have my parting on the left and could not get this to look as good worn this way as wants to fall with part on the right – if this matters to you. Comes with a hair net to wear under. Great value for money, my daughter wanted it as she has had to have her hair cut short & this looks great, she is very pleased. Fits perfectly, had to cut it as its way too long, i also made a fringe. It came in a beautiful box but it was tangled and it shredded some hair. All together i’m really happy i brought this. I have blue hair at the moment and had to go to a family function and this did the trick in looking real enough to pass off as my own, its a little bit darker than i was hoping but with a little bit of cutting it looked like my own.

Share Facebook Twitter Google + LinkedIn Pinterest No major changes this morning. Dry weather will take control for the next 2 days over the state. Cooler air pushes in over the state, but we are staving off the bitter cold push still until this weekend. We should see a good mix of clouds and sun today, and winds should subside over the gusty set up we saw yesterday. We start to dry down tonight and see dry weather for tomorrow and Thursday too. Rain is back for overnight tomorrow night through Friday. Moisture totals remain mostly unimpressive and we are bumping our forecast at .1″ to .7” over 70% of the state, but most of the rain totals above .4″ will be down near the river. Temps go near to below freezing overnight tomorrow night and do not recover Friday morning through much of the day. This may allow for some wet snow to mix in with our precipitation, even though it is light. The map at right shows liquid equivalent moisture totals through the end of the day Friday. Dry and significantly colder air returns for the weekend. Temps will be well below normal, and there no change in our thoughts about the potential for Saturday to see daytime highs stay below freezing over parts of the state. Sunday can be sub-40 for highs over a large part of the region. We stay dry Monday through Wednesday of next week. We likely see clouds from time to time, but no new precipitation. Thursday, we see Clouds build and then have a chance of scattered showers north of US 30 in the morning. The rain threat extends to statewide by mid to late afternoon and goes through the overnight. We can see from .05”-.25” with 70% coverage. For the extended period, we are dry for next Friday and Saturday. But, then we move into another wet, active period for Sunday the 18th through Wednesday the 21st. We see at least 2 waves of moisture moving over the eastern corn belt in that time, perhaps more. Combined rain totals will be from .25”-.75” with the heaviest rain chances in the southern half of the state.
Does it pay to turn down the heat at night when you have a radiant-floor heating system? David Meiland and a heating contractor are having trouble seeing eye to eye on that question.Meiland says the house they’re discussing is a slab-on-grade with R-10 insulation below and PEX tubing cast into the slab. In another part of the house, the floor is framed, with PEX installed below in tandem with aluminum plates that help distribute the heat. The boiler is a 30-kW electric model with an outdoor reset.In a Q&A post at GreenBuildingAdvisor, Meiland writes, “The heating contractor advised the homeowner that setting the night-time thermostat temperature too low would cause the system to work very hard in the morning to get the slab back up to temperature, and therefore waste energy.“My opinion is that lowering the setpoint at night is a good thing, as the system will put fewer BTUs into the house, saving energy. When the system ramps up in the morning, it will reheat the slab without any loss of efficiency. Fewer total BTUs will be put into the house.” High-mass floors respond slowlyWhile there is a mix of flooring types in the house, several readers pointed out that the high mass of a concrete slab will not change temperatures very quickly — and that has a bearing on the practicality of turning down the heat at night.Cramer Silkworth, for example, writes that if the house is well insulated, its occupants may not experience an overnight drop in temperature even with the thermostat turned down. “The slab’s mass combined with a well-insulated envelope may carry it through the night with only a small drop in temperature,” he says.When morning rolls around, he adds, it will take some time before the slab can be brought back to temperature. “The system won’t ‘work hard’ to bring the slab back up to temperature (it may be at full load, but the heat’s not being lost any faster than it normally would),” Silkworth says, “but it will take some time, such that you’d need to set the system to come on a couple hours before you want the morning temperature reached.”The relatively slow response to change also can lead to uncomfortable temperatures both in the morning and later in the day, Keith Gustafson says.“If the setback is too deep and the concrete loses significant temperature, it will take hours to reheat, and the residents may be uncomfortable,” Gustafson writes. “Radiant just does not recover like baseboard or hot air.”“In the morning,” he adds, “your thermostat turns back on but the physics of thermal mass say you need to put ‘x’ BTUs into the slab before it will rise in temp, and thus allow the room to rise. If you put enough BTUs into it quickly enough to ramp room temperature up, then the mass will cause it to overshoot — and how does having the room at 78 degrees 3 hours after you go to work save energy?”Dan Kolbert makes the same point. Not only does it take a long time for the temperature to come back, but it puts a strain on the heating system. “One client went away on vacation, turned the heat down to 50,” Kolbert writes. “It took almost a week to get back to temperature, and she had very little hot water while she waited.” RELATED ARTICLES All About Radiant Floors Radiant-Floor Heating Goodbye Radiant Floor Is Radiant Floor Heat Really the Best Option? Heating a Tight, Well-Insulated House Radiant-Floor Heating: When It Does—and Doesn’t—Make Sense The heating system may be overkillGBA senior editor Martin Holladay adds another wrinkle to the conversation: in a tight, well-insulated house, you don’t need much of a heating system when the design temperature is a relatively balmy 30 degrees, as is the case with Worthington’s house.“What you need is a good airtight envelope with high levels of insulation and excellent windows,” Holladay says. “If you have those features, you won’t need much heat at 30°F — certainly not a high-mass radiant floor with a condensing gas water heater. Your internal loads — the refrigerator, lights, and TV — will provide much of your home’s heat. A few ductless minisplit units are all you will need for cool nights.” Would better thermostats help?Writing from the San Francisco Bay area, Monty Worthington describes the trouble he’s had in regulating temperatures in his new house with radiant-floor heating and very basic thermostats. After some tinkering, he’s learned that a 3-degree setback overnight and in the middle of the day seems to work. But he has to program the heat to kick on at 5 a.m. in the bedroom in order to be comfortable two hours later when he gets up.Meiland says he had the same experience while living in that area in a house with a staple-up radiant floor system. “When the temperature swings were in the 30-degree range, it was necessary to start gaining or losing heat 3 to 4 hours in advance,” Meiland says. “This was a quick-responding system: 7/8-in. fir plank subfloor, 5/16-in. hardwood over, well-insulated underneath.”AJ Builder suggests that a forced-air heating system has faster response times than radiant-floor heat, but Worthington wonders whether a more sophisticated thermostat would help.Silkworth had earlier suggested that some thermostats are capable or learning how long it takes the heating system to reach the set point and automatically compensating for it.Kevin Dickson writes, “The newer Honeywell thermostats can ‘learn’ the temperature response of your house and compensate to prevent overshoot in any house.” Meiland thinks the heating contractor has it wrong, confusing a period of high demand in the morning with low efficiency.That’s the focus of this month’s Q&A Spotlight. Our expert’s opinionHere’s how GBA technical director Peter Yost sees it:First, a bit of a rant on radiant floor heating. While there is no denying the thermal comfort of a radiant floor heating system, the following claims are often made but are just not true:Radiant floor heating is more efficient than other heat distribution systems.Radiant floor heats objects and surfaces, not the air (this is often cited to support #1 above).Even at peak delivery, radiant floor heating systems deliver a maximum 60% of their heat by way of radiation. The two factors driving radiant heat transfer are surface area and surface temperature differences. At floor temperatures in the low 90s (F), net radiant transfer, particularly with people (our surface temperatures are in the low to mid 90s), is minimal. And the thermal comfort of the warm floor is more one of [no-glossary]conduction[/no-glossary] to your feet than radiation.And as a slow-acting, high thermal mass system, any initial air temperature from setback is steadily eroded until at equilibrium, the air temperature profile of a radiant floor heating system is pretty much the same as any heating distribution system and more dependent on the performance of the building envelope.Just because someone decided to name this system “radiant floor heat” does not mean that the laws of thermodynamics and rules of heat transfer are suspended by terminology.It’s not that radiant floor heating cannot work well; it’s just that it is a very expensive way to provide space conditioning — and one that only provides heating, not cooling, at that.With any high-mass heat distribution system, setback can be a real balancing act between thermal comfort and energy efficiency. Sure, setback saves BTUs, but if the main advantage of radiant-floor heating is thermal comfort, the prolonged thermal lag of a high mass heating system in the morning or when you return home in the evening is not likely to be very welcomed.And depending on solar gain, particularly in the morning, overshoot can be a big problem with nighttime setback of high-mass heat distribution systems. Certainly, setbacks cannot be as deep as with faster-acting heat distribution systems.We have ramp-up, multi-input setback thermostats for heat pumps, ones that use outdoor temperature readings and patterns to minimize strip heat use. I don’t know if similar thermostats are available for radiant-floor heat, or if the heat pump thermostats can be used with radiant-floor heat, but they are not inexpensive and can be “fooled” by dramatic weather changes.The long and the short of it: Specify or use radiant-floor heating for its steady delivery of thermal comfort, not because it is more efficient or well-suited to energy savings associated with setbacks.
