NewsGnocchi – some really good fast foodBy admin – December 14, 2011 596 Email Linkedin Print Twitter Previous articleWarning issued to jewellersNext articleGrant payment delays forcing students out admin Facebook Advertisement WhatsApp GIVING a hat tip to a fast food theme as it were, this gnocchi dish is really very good and as with most things Italian in nature, it is all down to the sauce and the quality of the produce used. A good potato gnocchi is as much about the potato as anything else. So using a good quality potato, baking it and then shaping them may seem like a lot of work but the end result is simply amazing.Sign up for the weekly Limerick Post newsletter Sign Up WHAT TO DO For the gnocchi4 baked potatoes2 eggs150g flourPinch of salt and nutmeg (it works)For the sauce1 punnet of cherry tomatoesfresh basil – it’ll be foreign, but worth itparmesan cheese1 finely diced onion 2 cloves of garlicA light squeeze of tomato pureeOlive oilA little knob of butterWHAT TO DOFirst off, you must bake the potatoes, I find that baking them makes for a better result in my opinion. Also, I will say that there are several very good pre-made options out there and for those of you caught for time, they are perfectly acceptable to offer. Making your own gnocchi is something, like many of the Italian classics, that you must do at least once. Once the potatoes are baked, scoop the white flesh out of the skins and add the eggs and flour to a bowl and combine with the salt and the nutmeg. Shape into a long cylinder and cut them to small bite sized pieces. You can roll them into oblong shapes for that authentic feel and look. They will only take a few minutes to cook so have a pan of salted boiling water ready to cook them as they will only take three minutes to bring back to life. Meantime, get the sauce on by sweating the onion and the garlic in a pan with a little olive oil and butter. Add the cherry tomatoes and a little cup of water with the tomato puree. Some pasatta will suffice also. A sprinkle of sugar is an optional extra if you want to lift the sweetness. Allow that to reduce and let the tomato-ness shine through. Drop the gnocchi into the salted boiling water and once they have floated to the top, remove them and combine with the sauce. Top with some shredded basil and grated parmesan cheese.

CONRAD JENKINS, president of the Jamaica Taekwondo Federation, in response to martial artist Nicholas Dusard’s claims of bias, has issued a press release outlining criteria used in selecting Jamaica’s two-man team for a Pan Am Olympic qualifying tournament in Mexico this week.However, the criteria, prepared by sole selector Jenkins, conflicted with an audio recording of a team meeting during which Dusard had challenged him about his non-selection after trials at the National Indoor Sports Centre on February 26.Dusard, who won the -68 kg category at the February 22-26 trials, complained in a story published in The Gleaner on March 3, that he was denied a chance to compete at -80 kg and was never told that current world rankings would have been a determinant.A subsequent press release, sent by Howard Chin, general secretary, JTF, on behalf of Jenkins, stated three criteria used in selection – results from the 2016 US and Canada Opens, WTF Olympic ranking and ‘athletes with the best competition management and with the least or no illegal acts in the fight offs’.Speaking to The Gleaner after Dusard’s claims, Jenkins insisted the three criteria listed in his press release were the only determinants.However, during an audio recording presented by Dusard, the JTF president was heard singing a different tune when challenged by the fighter, admitting he had not mentioned the use of rankings before the fight offs.In addition, Jenkins went on to explain, at length, to Dusard and the other fighters that accomplishments in competitions “over the years” were also a factor, a criterion not included in his press release list of three.”If it was mentioned, it made no sense none of the -68s fought. If we knew it would have come down to rankings, Raymond, Bruce and I, we had no chance,” Dusard was heard saying on the recording.”A chance should have been given for us to maybe step up to Craig or Jason’s weight class to fight off for that spot. Based on what is happening now, none of the -68 people had a chance of going, so we came here to fight for no reason,” he added, at which point Jenkins interjected.”I understand what you’re saying, you’re expressing a good concern but let me take it another step. The ranking is just one but it’s more than the ranking. When you assess, the second leg of the ranking, let’s put the ranking aside, the second leg of it, we’re dealing with number two, who has been competing and awarded medals in fights over the last couple of years,” the JTF president said, before Dusard objected.”I understand that, sir, but that was never said. That was never said, that’s the issue,” the fighter said, at which point Jenkins agreed.”That part was never said before the fight off, that is true and that is where we take the next step away from the rankings to who has been awarded,” he said.Presented with the recording, to which he listened intently, a defiant Jenkins ignored its contents, saying, “the three criteria were sent”. He also claimed that Dusard’s request to go up in weight class was only made on the day of the fight offs.”On the day of the fight offs?” a stunned Dusard responded when contacted by The Gleaner.”How could I make that request on the day of the fight? Raymond James from New York and I, who fought -68, we both asked on the 22nd if we could fight -80. We both expressed our desire and willingness to fight -80. We were told no by Jenkins,” he said.United States-based fighters, Craig Brown (-80 kg) and Jason Grant (+80kg), winners of their respective divisions, were chosen by Jenkins to represent Jamaica at the March 10-11 Pan Am Olympic qualification tournament in Aguascalientes, Mexico.
Facebook is Becoming Less Personal and More Pro… Remember POGS? Don’t feel bad if you don’t – you’ve just dated yourself, that’s all. These round collectible discs were used to play a children’s game (also called POGS) back in the 1990’s. Thanks to the incredible popularity of these little tokens, collecting POGS became a generation-defining fad for the demographic group known as the millenials. Where baby boomers had baseball cards and Generation X had Garbage Pail Kids, the young members of Gen Y had their POGS. Now prepare yourself for POGS’ return – POGS 2.0, if you will. Except this time around, the chips have been wired for the digital age. And today, the “game” is a social network called FaceChipz instead of a old-fashioned variation on marbles. FaceChipz: If POGS Was a Social NetworkFaceChipz is a new social networking site designed just for kids. Intended primarily for the “tween” set who’s outgrown children’s websites but hasn’t quite aged into Facebook yet, FaceChipz merges real-world networking with an online component. After purchasing a starter set of five chips, the child has their parent register an account for them on the FaceChipz website. Then the game begins. The child registers all their chips online using the unique identification code found on the back of each token. When all the chips have been registered, they can be distributed to friends. In return, the child’s friends will hand them their FaceChipz. When the exchange is complete, the child returns to the computer to register the new codes from the chips they’ve collected. The end result is a social network of friends with a physical counterpart in the real world – a brightly colored collection of FaceChipz that can be toted around just like POGS were decades ago. Social Networking Training WheelsParents will appreciate the fact that the FaceChipz network offers a more secure and private environment for their kids than traditional social networking sites like MySpace and Facebook. No strangers can solicit friendship requests here – the child’s only online friends are those they’ve connected with in real life. There isn’t even a search mechanism for friends to find each other without first trading chips. While that design decision is obviously meant to keep FaceChipz sales steady, the company claims it has another goal as well: to prepare children for the online world of social networking. Reads the company website, “FaceChipz wants to help kids stay safe, but also enable them to communicate using today’s technology platforms…If your kids are savvy enough to make appropriate real world friendships, we believe that those relationships will be suitable and appropriate for the digital network they create.”Other privacy protections are offered too. For example, the code on the back is only valid upon first entry. Afterwards, if a lost chip ended up in a stranger’s possession, they couldn’t use the code to connect to the child. Also, FaceChipz profiles are designed so kids are only permitted to post a limited amount of information and their email address is not stored. FaceChipz makes sure that none of their site’s pages are indexed by search engines. Finally, when the child is ready to graduate to a more adult network, their account can be permanently deleted.Will FaceChipz Become the New POGS? All the elements are there that could make FaceChipz a success: collectible tokens, an online element and parent-friendly company ethics. There’s another bonus, too: the chips are cheap. A five-pack is just $4.99 at ToysRUs and the one-time site registration fee is only $1.00. If anything, the fee is only there so mom or dad get involved and are made aware of the child’s online activities. However, in this day and age, FaceChipz may be too innocent a portal to attract tweens. On a web filled with insane YouTube videos and the (often disturbing and occasionally pornographic) webcam-hopping service, Chatroulette, will a “your first social network” site even have a chance? Will today’s youngest generation take to a modern equivalent of POGS or have they seen too much already? Only time (and sales figures) will tell.Thanks to Springwise for spotting this.

This article is the second in a series on various building diagnostic tools used to sleuth out problems in buildings. If you missed it, you may want to read Part 1: Air before diving in here. I’m back to share more tools of the trade that I use for forensic examinations and to diagnose problems in buildings. The rough breakdown of these columns will cover the topics of air, heat, and moisture and the tools I use to identify how they are acting in a building. This time, we’re looking at heat, or more specifically temperature. One of my go-to tools in building investigations is an infrared camera, or IR camera, which is the focus of this column. IR cameras are not always problem solvers, but they often pick up anomalies that offer useful clues, and they always provide entertaining stories. This article isn’t intended as an introduction to IR cameras. There are plenty of training classes you can find for that. It is intended instead to show how I use IR cameras to scan wide areas for cold spots, hot spots, and other “thermal anomalies,” as we call them in our reports.RELATED ARTICLESHow to Look at a House like a Building Scientist (Part 1: Air)An Introduction to Thermal ImagingDoes Wasting Home Heating Make You See (Infra)Red?Blower Door TestingBlower-Door-Directed Air Sealing Examples of Infrared Observations To interpret infrared images, a color (or black and white) scale is used to represent surface temperatures. In the images below, I used a color scale where blue/purple show cooler temperatures, and yellow/orange show warmer temperatures. I should warn you that there have been plenty of times when my first glance at an infrared image resulted in the wrong answer. For instance, I walked into this house in rough frame, and was startled by the big warm thermal anomalies across the floor (Figure 1). Was heat running already, resulting in duct conduction through the floor? Nope, those are just the sunlit spots on the floor from the windows, and it wasn’t obvious at first because the sun had gone behind a cloud. Figure 1: Rough construction with mystery thermal anomalies on the floor A really shocking example of air leakage is shown in Figure 2. Why are there bands of warm brick surfaces in this wintertime shot of a multifamily building? Thermal conduction through steel structure, perhaps? Figure 2: Gross air leakage visible on exterior building enclosure/shell A look above the suspended ceiling showed a fireproofed steel perimeter beam above the concrete block/CMU and steel stud wall (Figure 3). If you look carefully, you can see a little bit of blue in the gap between the two. That’s blue Dow Styrofoam. The problem is clearer in the building section (Figure 4). The building has a structural steel frame with infill CMU block and steel stud framing, that stops short of the steel. And there’s no exterior air barrier on this building, so outside air (from the brick cavity) is free to get through the foam joints and come in through this half-inch gap around the entire building’s perimeter. Figure 3: Beam-to-wall interface (above ceiling) Figure 4: Air leak at gap between beam and wall The warm air leaks shown in Figure 2 were worst towards the top of the building, consistent with stack effect, or warm air rising. But the problems were worse than just energy use. During the summer, stack effect reverses, and the lower levels tend to suck on the brick cavity. They were pulling in enough outside moist air that they were having condensation and mold problems on their chilled water piping, above the suspended ceiling. Revealing water issues An IR camera can also capture water issues; the key is capturing conditions at the right time. Rainfall often cools surfaces (especially in summer), and evaporation also cools wet surfaces. In addition, wet surfaces have greater thermal mass, so when the outdoor temperature is rising or falling, their response will lag behind the rest of the building. This is shown at the windowsills of a masonry building in Figure 5. Windows or glass, unlike most wall claddings, shed almost all the wind-blown rain that hits them onto the wall below. As a result, windowsills are critical for draining this concentrated water away via drip edges, or else you end up with drool patterns below the windows, as shown. Figure 5: Exterior of masonry building, showing sill water runoff Thermal bridging through framing can be pretty obvious with an infrared camera if there’s an indoor-outdoor temperature difference. Figure 6 is a wintertime shot of steel studs, which are far more thermally conductive than wood studs. Thermal bridges such as uninsulated slab edges or structural steel embedded in insulated walls would show up in a similar way. Figure 6: Thermal bridging through steel stud wall construction One story that’s been passed down is that a homebuilder in Las Vegas once experimented with steel framing during a time of lumber price spikes. They sold the house to a smoker, and the surfaces of the steel studs were cool enough to plate out the smoke onto the interior of the walls, resulting in a telegraphed line at every steel stud. The builder ended up buying back the house from the owner. Infrared cameras and air One thing to remember is that an IR camera does not see hot or cold air—the IR camera is looking through the air, and only shows the temperatures of surfaces. So, you can see temperatures of what the air is affecting, but not the air itself. For instance, these floor-mounted heating registers throw air onto the wall very well in Figure 7. As a bonus, this demonstrates the Coandă effect, which is air (or other fluid) following an adjacent flat or curved surface, thus resulting in increased throw (check out ACCA Manual T for more). Figure 7: Hot plumes from floor registers in heating operation A problem-solving infrared observation was this wintertime shot inside a house in Figure 8. Why is the top of the room glowing? One clue is the ceiling-mounted registers in these first-floor rooms, which are the visible hot spots that are also blowing onto the tops of the walls. Figure 8: Thermal stratification from poor ceiling register distribution The problem was that these registers were built for horizontal throw, not vertical, so they ended up layering the hot air into the top of the room’s air sandwich, resulting in pretty spectacular thermal stratification. There was nothing that broke up the hot air at the top of the room, so it stayed there, and left the bottom half cold. If you have poured black and tans (Guinness on top of Bass ale in a pint glass), this heating system was basically doing the same thing, gently pouring out a layer of hot air on the top of the first floor’s air sandwich, without churning things up. The problem at this house was even worse than discomfort. With this stratification, the thermostat was typically below the hot-cold boundary line. So the heating system ran for hours until the hot layer got deep enough to affect the thermostat. The system would shut off, then the cycle would repeat. But of course, the second floor was sweltering the entire time. One last trick for visualizing airflows is something that I owe to Robb Aldrich at Steven Winter and Associates. If you want to visualize how an HVAC system throws air—for instance, a mini-split—put up a piece of cardboard that cuts a cross section of the air plume, and it shows up beautifully in infrared. Air + Heat (enclosure depressurization and infrared) A combination that many of you are probably familiar with is fan pressurization or depressurization plus an infrared camera to sleuth out building air leakage—we are combining the topics of air and heat now. This powerful technique relies on an indoor-outdoor temperature difference to visualize leakage We have the choice of pressurizing or depressurizing the building. Pressurization (forcing air into the building, Figure 9) results in “induced exfiltration” or outward leakage of interior air; the leak would be visible on the outside of the building. However, these air leakage thermal anomalies are often overwhelmed by outdoor surface temperatures, especially during the day, when the building is sunlit. Figure 9: Building pressurization Figure 10: Building depressurization Depressurization (pulling air out of the building, Figure 10) results in “induced infiltration” or inward leakage of exterior air; the leak would be visible on the inside of the building. This is my typical go-to technique. I recommend walking around the building with an infrared camera first to find any existing thermal anomalies (such as thermal bridges). Then, I would depressurize the house (turn on the blower door fan), and do another walk of the building, to see what has changed. One characteristic of air leaks is they often appear as plumes or jets of air, as shown at a leaky door bottom in Figure 11. Once again, this shows up on the surfaces being hit by that cold outside air (induced infiltration). Figure 11: Induced infiltration air leakage plumes at a door sill gasket (winter) Tongue and groove ceilings are a classic problem when they run from indoors to outdoors at the gable end or roof rake. Depressurization in wintertime shows air jetting in at every board joint (Figure 12). Figure 12: Air leakage at tongue and groove roof/ceiling that extends indoors/outdoors (winter) This technique can also be used to find air leakage hidden behind interior finishes. Figure 13 shows a vented cathedral ceiling during summertime depressurization: hot outside air is leaking in at the roof ridge vents, through fiberglass insulation, and is getting pulled inside via the recessed lights and other ceiling plane air leaks. Figure 13: Induced infiltration at cathedral ceiling; note ridge and recessed lights (summer) Similarly, Figure 14 shows outside air being pulled from the hot vented attic above the ceiling, down into the interior wall (“wing wall” at the bathroom) and the top plate of the outside wall. Figure 14: Induced infiltration at vented attic into interior wall and at exterior top plate (summer) Spray foam is often used because of its air-tightening qualities. It provides an excellent air barrier where it is present and continuous. However, at discontinuities where it is not present, it does nothing to stop airflow. In other words, spray foam doesn’t air seal when it isn’t there. This commonly occurs in wood frame construction at wood-to-wood joints, such as king/jack/cripple stud joints, corners, top and bottom plates, and rafter connections. An example of this is shown in Figure 15, which is a flash-and batt assembly (closed-cell spray foam and fiberglass batt) shown being depressurized in wintertime. A huge fan of cold outside air is getting pulled in at the roof-to-wall joint. Pulling back the fiberglass (Figure 16) revealed a row of unsealed wood-to-wood joints at the rafter-to-ceiling joist connection. Figure 15: Induced infiltration at spray foam/fiberglass (flash and batt) attic roof-wall connection (winter) Figure 16: Spray foam imperfections at wood-to-wood joints Another troublesome detail is windows that are installed using side clips (commonly called masonry straps) and/or window shims. Figure 17 shows a window that was well sealed around its perimeter, except where the shims penetrated through. The recommended detail is to cut the shims off flush, and to run the air sealing detail over the surface. Figure 17: Air leakage around shims at window-to-wall rough opening (summer) Good solutions to window side clips include using a tape seal covering the entire clip/strap (Figure 18) or embedding the entire clip in the same sealant used around the window perimeter (Figure 19). Figure 18: Covering installation clip with tape Figure 19: Air sealing window by embedding clip in sealant A bit about cameras I have only been using IR cameras since 2008, so I’m definitely not an old-timer from the days of liquid-nitrogen cannisters and cart-size cameras. I started out using a FLIR b40 (Figure 20), which sold for about $5000 when it was new, came in an armored Pelican case, and put out 240 x 240 pixel images (IR resolution: 120 X 120 pixels). Taking a $5000 instrument to bang around in an attic was never a comfortable feeling. Also, the image was a narrow soda straw view. You had to step back to get a good view of the building, and at that point, the image was too blurry to be useful. Here’s a tip: use a fixed temperature scale, snap multiple images in a panorama, and stitch them together in photo-editing software if you need to. Nowadays, we can all benefit from advances in technology. I currently carry around a FLIR ONE Pro, which plugs into a smartphone and runs about $400 (Figure 21). It puts out 1440 x 1080 pixel images, overlaying a visual image (showing edges) with the infrared shot. That overlay is a very useful reference (“Right…this shot was in the room with that godawful velvet painting”). That painting would be the same temperature as the wall, and mostly invisible with infrared alone. It also slips into your pocket for trips up to the attic. Simply put, today I get a better image at a tenth of the price. Figure 20: FLIR b40 infrared camera Figure 21: FLIR ONE Pro on a smartphone There are many brands and models available. I have not tried out the Seek IR camera, so I can’t offer any comparisons. However, I have a few warnings and lessons learned from my IR camera. I’ve gotten some pretty strange numbers from the temperature readout, so I rely on it more for the image than surface absolute temperature measurements. It seems like the phone battery drains quickly while running the software. Using this setup outdoors in winter results in really quick battery drain, so I need to tuck it into my coat between shots. Pairing infrared shots with visual shots (like I’ve done above) makes it much clearer what is going on in reports and presentations. Lastly—be careful of the connector that plugs into the phone: if you knock it around, it can fall right off (Figure 22). FLIR doesn’t repair these units, but they offer a discount on a replacement when sending back the broken unit. Figure 22: Breaking the connector off the FLIR ONE Pro Shiny surfaces and furry things IR cameras rely on an assumed value for emissivity—emissivity is the “E” in window “low-E” coatings. Shiny surfaces have a low emissivity and can result in weird results. Specifically, shiny surfaces reflect in infrared, the same way that mirrors do in the visual spectrum. I ran into this while scanning hallways in a building (Figure 23). “Wow,” I thought, “there are some serious thermal anomalies at that elevator door. Is there a massive summertime air leak? Oh wait, that’s a reflection of me and a colleague, as well as the overhead lights.” Yes, I accidentally took an infrared selfie. Figure 23: Infrared reflections on a shiny elevator door The same thing happens when you look up inside a suspended ceiling and point an infrared camera at shiny sheet metal ductwork. The tell is when that thermal anomaly starts moving around as you move around. Lastly, you sometimes run into surprises with an infrared camera as shown in Figure 24. I was scanning a client’s basement thinking, “Cool basement walls, warm water heater, hot pipe…WHAT THE WHAT IS THAT?!” If you turn on a flashlight (or turn up the brightness in the visual shot), you’d see that the homeowner’s black cat likes to perch on the basement wall.

DharmendraHe claims to be as young as ever even at the age of 75 and Bollywood’s original ‘He-Man’ Dharmendra says the secret to his energy lies in the love people have bestowed on him.”I love people and they love me and that is the secret of my energy and youthfulness,” said the veteran actor in a brief chat here this afternoon.The superstar of yesteryears has completed fifty years in Hindi cinema having worked in over 300 films. His latest film Yamla Pagla Deewana with sons Sunny and Bobby Deol released only last month.Dharmendra , on his way to Jalandhar with the torch of the Shaheed Bhagat Singh International Wrestling Tournament commencing on February 10, 2011, claimed that whenever he visited Punjab, he felt as if he had come back to his mother.Having studied and worked in Phagwara for a few years before leaving for Mumbai way back in 1959, the actor went down the memory lane to talk about his roots.His father, Master Kewal Krishan, was a teacher in the local Arya school and Dharmendra addressed him as ‘Babuji’. “Main es mitti da haan te ih mainu badi pyari lagdi hai (I belong to this soil and love it too much),” said Dharmendra. He asked the Punjabi youth to take to sports for their own health and the progress of the country.Earlier, addressing a gathering in local Hargobind Nagar, Dharmendra extended his love to those younger than him – “jaffi pa ke pyar (love with a hug)” to his “hanis (those of his age)” and respect to the elders.He was also honoured by the Kapurthala District Wrestling Association. Despite tight security and a busy schedule, the veteran actor gave his blessings to two girls who were struggling in the crowd trying to reach him.advertisement
