Shark Glows in the Dark

first_imgThe “Eye-in-the-Sea” infrared camera (see 08/26/2004) found all kinds of exotic life in the Gulf of Mexico, reported EurekAlert with pictures.  The submersible with its dark-light camera is able to sneak up on organisms without scaring them.  The team from Harbor Branch had to dodge Hurricane Katrina, but scored on its second annual mission with a new gallery of deep-sea marvels, including a crab that can see ultraviolet light, a fluorescent sea anemone and a shark that glows in the dark.No evolutionary talk, discovering new things – science can be good.  The deep sea organisms didn’t seem to notice the hurricane.(Visited 8 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Coping With a Wrong-Sized AC System

first_imgSaving Energy With Manual J and Manual DGreen Basics: Cooling Options Q&A: Excess humidity — HVAC system too largeHumidity, Mold, and Indoor Air QualityHRV or ERV?Climate-Specific Air Conditioners That’s the topic for this Q&A Spotlight. RELATED ARTICLES Try a stand-alone dehumidifierGBA senior editor Martin Holladay suggests that Marriner begin with a stand-along dehumidifier. “It may work well enough for you to tolerate your system,” he says. “And it is a cheaper solution than starting from scratch.”To help the existing AC equipment get more water out of the air, Holladay says, is to lower the blower speed of the air handler from 400 cubic feet per minute (cfm) per ton to 350 cfm per ton. “Of course, lowering the blower speed (especially below 350 cfm per ton) carries its own risk,” he adds, “namely, freezing the coil.”Holladay’s suggestion for a dehumidifier is a good one, Dana Dorsett says. “If the house is reasonably tight it should do the trick,” he writes. “A 600-watt stand-alone dehumidifier converts the latent load into a sensible load, but it doesn’t increase the total cooling load by more than ~2000 Btu/hr (the 600 watts it’s using while running).(For more on sensible and latent loads, here’s an explanation from a website called The Engineering ToolBox.)“I wonder how many other HVAC technicians there are out there who take the approach of increasing the load as the ‘solution’ to an oversized AC system?” he adds. “If it’s a vented attic, it would also increase the latent load. You may end up pretty much in the same place, but be using significantly more electricity.” Florida is not the kind of place where you’d want to be without air conditioning for very long, so when Chris Marriner’s old system died last spring, he didn’t waste much time in replacing it. But what should have been a ticket to indoor comfort hasn’t exactly worked out that way.Marriner’s HVAC technician decided to replace the 4-ton system with one of the same capacity, even though Marriner knew that because of improvements to the building envelope the new system probably would be oversized for the 2200-square-foot home. The tech told Marriner the system could be “tuned.”In a Q&A post at GreenBuildingAdvisor, Marriner complains that indoor relative humidity averages 55% or more, and has ranged up to 66% or 67%.That’s apparently because the oversized AC equipment doesn’t run long enough to lower indoor humidity. When Marriner spoke to the HVAC installer about the oversized equipment, he got some strange advice.“I talked to him about it and he wants to bring some attic air into the return so [the AC] will run longer,” Marriner writes. “I think that adding a whole house dehumidifier, like the Williams Air Sponge, or Aprilaire would be the best solution. Any feedback?” HVAC tech’s idea is non-starterNathaniel G finds the suggestion to bring hot attic air into the system to extend the run time nothing more than an “inefficient Band-aid.” The system should have been sized correctly in the beginning.“Sounds like your HVAC tech is less interested in doing his job properly than doing it the way grandpa did and upselling you on a bunch of crap to patch up his own mistakes when grandpa’s approach doesn’t cut the mustard,” Nathaniel says.“Bring some attic air into the return?” writes David Meiland. “You mean deliberately and needlessly increase the load so the unit will run longer in hopes that it will also decrease humidity adequately? That’s nuts; in fact it might be one of the worst ideas I’ve ever heard — it’s about the same as opening a window.”It’s not clear what the tech might have meant when said the new system could be tuned, Meiland adds, but the real solution is longer run times and an indoor coil that’s not so cold.Marriner has already explored the possibility of replacing the outside compressor and scaling back the air-handler. The manufacturer told him that won’t work.“To compound this,” Marriner adds, the HVAC technician is a friend. “If he were not, I’d have raised hell. He got indignant when I asked him about the humidity and said he will not change the unit … He was trying to cut me a deal, so I don’t know if he had an extra one at the warehouse or what. But I’ve learned a valuable lesson.” GREEN PRODUCT GUIDE Humidity Control Equipment Excuse me, but what’s the fuss about humidity?The indoor humidity levels sound normal, says AJ Builder. “I have no AC and my summer humidity is 50-85% in my home, about 10% less than outside,” AJ writes. “No mold except for bad tile work in one shower. Fifty-five seems right considering Tampa, where outside humidity is high along with the temperature.”People are healthy and comfortable, Dorsett replies, when the indoor relative humidity (RH) is between 30% and 50% and the temperature between 68° and 75°F.“When it’s above 50% RH, dust mite populations begin to grow (a problem primarily for those with allergies or asthma),” Dorsett says. “Above 60% RH @ 75°F, humans are more susceptible to skin fungus/yeast infections. Above 70% RH it can be pretty uncomfortable, mold spore counts take off, and the risk of respiratory tract infection (fungal or bacterial) goes up.”In Tampa, where Marriner lives, high dew points mean that any infiltration of outside air brings in a lot of humidity. “The airtightness of the house and ventilation rates matter quite a bit,” he says.AJ isn’t buying it: “People who live in a ‘clean room’ are screwing up their immune systems,” he says. “We need to interact with the real world to have healthy immune system understandings IMO and finally in some research published of late.“And Florida, to reduce humidity to 55% (which he has) is fine,” AJ adds. “Dehumidify maybe just a bit; but in cooler weather, open windows and be part of this great planet.”Like it or not, Dorsett replies, but at 65% humidity “you won’t have serious mold issues, but if you have dust mite allergies you’re pretty much screwed — they breed faster than flies at that RH.” Moreover, dew points tend to be a lot higher in Tampa than they do in New York (where AJ Builder lives) or in Massachusetts (where Dorsett lives).“That 70°F/55% RH outdoor air you’re currently experiencing has a dew point of 53°F, whereas in Tampa right this second it’s 92°F, with an outdoor dew point of 72°F (down from the mid-70s from earlier in the day),” Dorsett tells AJ. “Tampa’s average outdoor dew point is about the same as our absolute summertime peak dew point so far this year. (On July 15th the dew point hit 74°F at my house according to WeatherSpark.com data sets — which was the highest reading of the season.)” Our expert’s opinionHere’s how GBA technical director Peter Yost sees it:Higher interior relative humidity can easily feel uncomfortable when you are also dropping the air temperature with air conditioning. Sure, some folks actually do just fine with plenty of air movement at 80°F and 55% RH, but many folks don’t.There is no excuse for any HVAC technician not to size an AC system based on the real loads, or to fail to specify the appropriate sensible heat ratio (SHR – the portion of the total cooling load handling the sensible load) for the climate. SHR for a Florida climate should be 0.70 or below. As Martin Holladay notes in his blog, Climate-Specific Air Conditioners, most air conditioners have an SHR in the 0.75-0.80 range — much too high for a hot humid climate.Installing a dehumidifier to drop the interior relative humidity will likely do the trick, but most dehumidifiers are meant to work in just one room or space, unless the unit can be configured into the central forced-air system. (For more information on this approach, see this Building Science Corporation / Building America report). This fix will be more expensive and challenging in a retrofit than it would be in a new home.The bottom line: get your HVAC good buddy to become “sensible” about loads and how to condition his friends!last_img read more

It’s often difficult to determine which funds are personal, which are political, and the case may be turned over to another US Attorney’s Office because of a potential conflict of interest after three prosecutors attended a Hillary Clinton fundraiser while pushing the investigation.KUSI’s Steve Bosh has the details: Former US Attorney Charles LaBella on the Hunter investigation Steve Bosh, last_img read more

LETTER TO THE EDITOR A Shady Lane Resident Speaks Out IN FAVOR

first_imgDear Editor,This letter is directed at the people who have concerns and are opposing the special permit for a a detox facility on Middlesex Avenue.I applaud you all in wanting to protect your children and grandchildren from the ugly reality around addiction. That is one thing everybody is on the same page about. I encourage you all to read the police log as the Wilmington Apple posts it daily. Almost every week there is at least one drug or alcohol related incident. That’s alarming in the town my son is growing up in. On December 3rd a man was arrested for trafficking over 10 grams of fenantyl. There are so many alarming opioid epidemic statistics RISING at a scary rate that I just don’t have the time to read all of them to you today. Detox admissions in Massachusetts have more than tripled in the last 5 years. The number of overdose deaths in this state is more then 10x what it was 8 years ago. Close to 1800 just this year of confirmed opiate related deaths. If we continue the same approach towards addiction that we have these last 8 years then those numbers will surely continue to rise, and anybody can fall victim. Massachusetts has done a great job in effort to rid the stigma associated with addiction. I don’t want addiction to affect anybody the way it’s affected me before you change the way you view it. How is NOT LETTING a detox open going to protect your children? The statistics in Massachusetts alone, and your police log here in Wilmington make it very evident that unfortunately our community is already being affected by this epidemic.With that being said I understand there are some other concerns. All of which are tied directly to assumptions about addiction, what it is, who it happens to, how we treat it, what works and what doesn’t — most of which are ludicrous if you understood addiction but I will address them anyway. One being property values. Although there is no reliable statistics to prove this could happen as a direct result of a medical detox facility opening, I want you to ask yourself: if the detox doesn’t open and go in this vacant lot, what will? What is going to be opposed next that could potentially affect property values. The other concerns regarding this detox come from a place of concern. I understand that, but if you do enough research and realize how much our community has been affected by this epidemic, I think your concerns would change, considering the ugly truths around addiction are already right here in your neighborhood.YOU SHOULD ALREADY BE CONCERNED YOUR CHILDREN OR PETS COULD BE POKED BY AN IMPROPERLY DISPOSED NEEDLE, because it’s already happening. A detox would have sharps containers and people trained to deal with that kind of stuff. The applicant for this permit also specified he was willing to have 24/7 security. I can’t imagine somebody will be scattering needles in front of a security guard. Secondly, he also assured the board he is willing to find out what kind of waiver he can have patients sign so that police can be notified if a client AMAs and doesn’t follow proper procedure to be given a ride by staff somewhere out of the community or on a train.For the people who’s backyards are sharing property lines with the proposed site, you bought property sharing property lines with a vacant lot.What mostly baffles me is people saying that if the detox goes up, they will be moving because they are concerned for their children’s safety. I encourage you next time you buy a home to research your neighbors. Had you done that when you moved in you’d find many people whom have lived in my home with me have struggled with addiction, overdoses, section 35s, arrests, and drug related incidents. I am grateful life is better now. I hope if addicts are so concerning to your children’s safety that you won’t allow them to walk to Elia’s, that you also would not allow them to walk by my house when I or anybody else was actively using.Truthfully the things that have been said resemble an uneducated and mostly inexperienced speculation on an entire group of people. You’re afraid for your children IF IT OPENS and I AM AFRAID FOR MINE RIGHT NOW. If you’ll say these things at a public hearing, what will you say to your kids behind closed doors? What misinformation are you spreading that your children may carry with them, and my son may hear someday on the bus about his parents whom suffer from addiction. The comments made to me inside and outside the meeting, will the blatant childish tantrums also happen when I walk the neighborhood with my 3 year old?Thank you and have a nice day.Sincerely,Rachel DiDomenicoLike Wilmington Apple on Facebook.

Also impressive: Mpow’s 18-month warranty.Here’s what I don’t like: The circular play, pause and volume button panel embedded on the right earcup isn’t easy to navigate by touch. There’s not enough tactile differentiation between the buttons. Also, while sound quality is a highly subjective thing, to me these sound good, not great. Maybe I’ve just become over-accustomed to noise-isolating earbuds, which provide much richer bass than you get here. But I’d say if you want an ultra-high-fidelity experience, look elsewhere. If you just want background music while you work or podcasts while you ride the commuter train, these fit the bill.I may be a harsher critic than most: As noted earlier, nearly 22,000 Amazon buyers collectively rated the 059 4.5 stars out of 5. That’s pretty telling. Indeed, as a potential dad or grad gift, this is probably a winner.Your thoughts?

25 killed in Saudi air strikes on Yemen market

first_imgAt least 25 Yemenis were killed when Saudi-led coalition aircraft struck a market in the northern Saada province, a local health official said on Sunday, the latest in a string of deadly incidents in the 27-month-old conflict.Officials from the Saudi-led coalition could not immediately be reached for a comment on the report.Yemen has been torn by a civil war in which the exiled government of President Abd-Rabbu Mansour Hadi, backed by the Saudi-led coalition, is trying to roll back gains made by the Iran-aligned Houthi group which controls most of northern Yemen, including the capital Sanaa.The director of the Houthi-run Health Department office in Saada said the aircraft conducted two raids on al-Mashnaq market in Shada district, which is close to the Saudi border, on Saturday, killing 25 people and wounding at least one.“Rescue teams were unable to reach the area for some time for fear of being hit by artillery shelling of the area,” the official, Dr Abdelilah al-Azzi, told Reuters by telephone.Reuters could not independently confirm the report because the area is located very close to the frontline, but several Yemeni online news outlets carried a similar report.A Saudi-led coalition air strike killed 22 people and wounded dozens when it struck a market in western Yemen near the Red Sea fishing town of Khoukha in March.Khoukha and the nearby city of Hodeidah are controlled by the Houthis who overran Sanaa in 2014 and moved south to Aden in 2015 forcing Hadi and his administration to flee into exile.The Yemen war has killed more than 10,000 people, displaced more than three million and ruined much of the impoverished country’s infrastructure.The Saudi-led coalition was formed in 2015 to fight the Houthis and troops loyal to former President Ali Abdullah Saleh who have fired missiles into neighboring Saudi Arabia.In December, the coalition acknowledged it had made “limited use” of British-made cluster bombs, but said it had stopped using them.Nearly half of Yemen’s 22 provinces are on the verge of famine, according to the UN World Food Programme.last_img read more

The charm of Punjabi folk

first_imgThe two-day festival of traditional Punjabi music opened in the national capital, putting the spotlight on Kheyal Gayeki tradition of Punjab that has enchanted lovers of Hindustani Classical music.Deputy Chief Minister of Delhi, Manish Sisodia inaugurated the festival.  Jetinder Singh Tomar, Minister for Law & Justice; Tourism; Gurdwara Elections and Art, Culture & Languages, Govt. of Delhi was the Guest of Honour. Also Read – ‘Playing Jojo was emotionally exhausting’If one talks about the cultural heritage of Punjab, the mellifluous kheyal ‘bandishes’ (Compositions) cannot be left out from the discourse. In fact, this is a genre of gayeki which has enriched the Hindustani Classical music for more than two centuries now. Punjabi Academy, Govt. of Delhi, Department of Art, Culture & Languages, Govt. of Delhi; has brought together renowned artists of this genre for two days May 21 -22 at the India International Centre. Also Read – Leslie doing new comedy special with NetflixThe festival began with a performance of Bhai Balwant Singh Namdhari who rendered kheyal gayeki with tabla mridang in the traditional style of Punjab. His performance was followed by Raza Ali Khan who sang the traditional Punjabi Kheyal bandishes. Before the advent of Kheyal, there were four famous Gharanas of Dhrupad singing in the Punjab, Talwandi, Haryana, Sham Chaurasi and Kapurthala. Kheyal Gayeki emerged as the next stage of evolution in the history of Hindustani music as the strict discipline of earlier days gave way to greater expansiveness and liberty of expression in the musical firmament. The process of this evolution had started with the creative endeavors of Amir Khusroe in the 12th century and completed itself under the vibrant outpourings of Niamat Khan Sadarang and Ferozkhan Adaran who gave the Kheyal style its present stamp.  Kheyal Gayeki remained confined to Delhi for some time, and it was only later during the 19th century that the new style reached the Punjab. From Delhi, it was first taken to Gwalior where Haddu Khan and Hassu Khan laid the foundation of the Gwalior Gharana of Kheyal singing. Banne Khan Nangliwale learnt from them and went to Punjab and taught stalwarts such as Pyare Khan, Umaid Ali Khan and Mubarak Ali Khan. Meanwhile, Jamail Ali Bakshi and Kaptaan Fateh Ali of Patiala became Shagirds of Tanras Khan of Delhi who had also learnt from Haddu-Hassu Khan of Gwalior, and from Mubarak Ali of Jaipur (son of Bare Mohd Khan). They founded the Patiala Gharana of Music, from which flows an important line of Kheyal Gayeki of the Punjab. This genre of gayeki further evolved over the 20th century and adopted new ways of rendition and musical instruments.“As you are aware the Punjab has always been renowned for its beautiful bandishes which have enriched the repertoire of Hindustani Classical Music. Punjabi is the only other language, apart from Braj Bhasha, in which Kheyal Bandishes have been written over the centuries. Shah Sada Rang and Ada Rang, creators of the Kheyal style of Hindustani Classical Music, have also composed some beautiful Bandishes in Punjab which will be presented in this Festival. Over the last two centuries, Hindustani Musicians whether from the Punjab or elsewhere, have sung these Punjabi Kheyal compositions. It is our effort through this festival to revive an interest in them by encouraging their research and presentation. ,” says Geetanjali Gupta, Secretery, Art, Culture & Languages, Government of Delhi.The second day of the festival will have Qutubi Qawwal from the Dargah presenting the Sufi Qawwali from Punjab and Pandit Yashpaul rendering the Punjabi Kheyal Bandishes.“Through this annual festival, our effort is to revive interest and attract youngsters to this beautiful form of classical vocal music. We also want to encourage research and presentation in the art form that is an intrinsic part of our composite culture,” says Jawahar Dhawan, Secretary, Punjabi Academy.last_img read more
