A recently published article on New York YIMBY states that the Landmarks Preservation Committee is currently reviewing a proposal to renovate the facade of 55 West 86th Street, an 1889 townhouse located between Central Park West and Columbus Avenue.

The architect on record is Opera Studio Architecture. The company released a rendering of its proposal which includes signage from Book Culture.

However, a representative from the architecture firm tells us the retail space has not been leased.

Weve reached out to Book Cultures owner, Chris Doeblin, to inquire as to whether he plans on leasing space at the building once it is renovated, and to ask whether or not he was aware that his signage was being used in the rendering. Well provide an update if and when he gets back to us.

Book Culture closed its Columbus Avenue store in early 2020, after lots of back and forth between Doeblin and the owner of the building at 450 Columbus Avenue. The Strand Bookstore took its place and opened in July of 2020.

Opera Studio Architectures proposal includes replacing windows on the third and fifth floors, adding a large arched window above the ground floor, updating the signing, adding limestone panels, and installing new entry doors, according to New York YIMBY.

Heres a look at the building in its current form, which includes five apartments and the retail space:

Rendering of Proposed Townhouse Renovation Displays Book Culture Signage - I Love the Upper West Side

Q: I have a 2002 Buick Century Limited in excellent condition. I bought it two years ago from a little old lady who had driven it only 11,000 miles. Really! But it has a vexing problem. The power windows work only occasionally. The rear ones will not work at all, the front passenger side window usually does, but the driver's window seems to work only when the temperature is 65 degrees or cooler outside. I replaced the armrest switch panel and checked the fuses, but the problem has persisted. Any ideas?

A: The problem might not be in the electrical system, at least not in the switches. Because of the lack of use, the window lift mechanism might require more oomph than the motors can supply. When that happens, the motors can overheat and fail. If the motors demand too much current, circuit breakers open. In many cases, the circuit breakers will reset after resting a while as things cool. Let's hope that the motors haven't been damaged.

Outgassing prevention

Q: My wife's 2017 BMW coupe sits outside in south Florida. Every two or three days, we have to clean the inside of the windshield from what I believe to be outgassing. Is that the most likely cause? If so, how do we prevent it?

A: Yes, that most likely is the cause. You could use one of the many interior protection products. Most are available as sprays or wipes. That won't eliminate the problem, but it might slow down things. Another option is a dashboard cover. It is similar to the car's carpet, custom made for your vehicle, including cutouts for vents, sensors, speakers and other stuff.

Nail gymnastics?

Q: From my experience in fixing nail punctures in my shop, it was mostly rear tires that suffered. As the front tire runs over the horizontal nail, it flips up in the air just in time for the rear tire to "nail it."

A: You are one among the teeming masses who wrote in to describe this phenomenon. It is one of those things I would like to view in slow motion.

Fob hackers

Q: We saw a magazine article that said keyless entry fobs can be hacked by crooks using a fairly simple device to pick up the signal from your fob. Does this mean keyless entry fobs are always transmitting a signal? The magazine article recommended buying a Faraday Cage/RFID blocking pouch to keep your fob in. Any thoughts?

A: There are memes about bad guys using signal amplifiers to intercept the signal from your key fob to unlock your car and steal your stuff. Yes, there is a low-energy signal continuously emitted by the fob. I don't think this is a major problem, but if you are worried about it, you might want to get a Faraday pouch essentially a metal mesh fabric that blocks electrical signals in which to store your fob, And while you're at it, keep your good stuff out of sight.

Motor Mouth: Malfunctioning windows an open and shut case - Minneapolis Star Tribune

Just like last week, the Falcons will be without a lot of firepower on defense. Dan Quinn announced today that two starting safeties Keanu Neal and Ricardo Allen will not play Monday night against the Packers. Younghoe Koo, who suffered a groin injury during warmups before their game against the Bears, will also not play.

The Falcons signed former South Carolina kicker, Elliot Fry, earlier this week. He will take over the kicking duties against the Packers and probably the next couple of weeks after that, providing he looks serviceable on Monday. Expect to see a lot of Damontae Kazee, Jaylinn Hawkins, and Sharrod Neasman at safety with Allen and Neal out.

Unfortunately, the Falcons could also be without a key piece on their defensive line. Dan Quinn is hopeful Takk McKinley can return this week, but he will be a gametime decision.

The good news is wide receivers Julio Jones and Calvin Ridley look like they will play. Russell Gage will also be out thereafter suffering a concussion against the Bears.

Global Hormone Replacement Therapy Market: Overview

Hormone replacement therapy refers to the treatment of the patients with growth hormone deficiency due to conditions such as dwarfism or women nearing menopause, which requires replacement of hormones in the body whose levels have become low. Currently, a combination of drugs are used to treat hormone deficiencies, which are known to have better safety and efficacy parameter. Globally, the cases of hormone deficiency is escalating and a vast patient base are deprived of the proper treatment. These two factors are the primary drivers of the hormone replacement therapy market, which is projected for a healthy growth rate during the forecast period of 2016 to 2024.

Global Hormone Replacement Therapy Market: Trends and Opportunities

The rising incidences of hormonal imbalance disorders and increasing geriatric population as well as the neonatal population suffering from hormonal deficiency are the primary drivers of this market. Technological advancements in the field of drug delivery systems, presence of routinely monitored formulations, and increasing awareness among the consumers are others factors favoring the growth rate of the market. Additionally, the report also observes that menopausal females form a major chunk of the demand. Consequently, the rising population of female between the age group of 45 to 59, which thereby increases the range of menopausal window, is adding to the demand in the global hormone replacement therapy market. As per the American Congress of Obstetricians and Gynecologists, nearly 6,000 women reach menopause on a daily basis, in the country of the U.S. alone.

Hormone Replacement Therapy Market: Rising incidences of hormonal imbalance disorders is the primary drivers of this market - BioSpace

KEY POINTS

Liverpool star Sadio Mane reportedly could consider moving to FC Barcelona in the ongoing summer transfer window.

With Lionel Messi having informed Barcelona that he wants to leave this summer, the club is looking for a long-term replacement for their skipper. Barcelonas new head coach Ronald Koeman managed Mane at Southampton and is believed to be an admirer of the Senegal national and has identified the 29-year-old striker as an ideal replacement for Messi.

Under the watch of Koeman, Mane rose to ranks and netted 25 goals in 75 competitive matches at Southampton between 2014 and 2016. Impressed with Manes show with "The Saints", Liverpool had signed the player for $45 million on a five-year deal.

Mane was linked with a move to Real Madrid last summer and the player was reportedly angry with Liverpool for not even considering or discussing the same with him.

The 28-year-old winger has been a core member of Jurgen Klopps side that has tasted success over the last couple of years. He has scored 81 goals in 171 matches since his Reds debut in 2016. As a reward for his contribution, Mane was offered a new lucrative five-year contract in 2018. Along with Roberto Firmino and Mohamed Salah, Mane has formed a mind-blowing front three at Liverpool helping the side win the Champions League, the Premier League, UEFA Super Cup, and their maiden FIFA Club World Cup.

While in the Ballon dOr awards, only journalists vote, international coaches, captains, and the media vote for FIFA awards. Messi, who won the record sixth Ballon dOr award in 2019, had voted for Mane for his stellar 2018-19 campaign that saw the Senegal striker score 26 goals in 50 matches, across all tournaments.

It has been reported that Liverpool could lose two of its talented players this summer: Mane and Georginio Wijnaldum.

While Mane has three years left in his current contract, Wijnaldums Liverpool deal is due to expire in 2021 and the Dutch midfielder has not been offered an extension yet. Both the players reportedly are wanted by Barcelona as their new boss Koeman has a great relationship with both. Under Koeman, Wijnaldum played a key role in helping Netherlands reach the final of the UEFA Nations League, which they eventually lost to Portugal.

Spanish publication Mundo Deportivo has claimed that Mane has been unhappy at Barcelona and is ready to consider an offer from Barcelona. The report has revealed that Mane feels he is not given the same importance as Salah, Firmino, or Liverpool captain Jordan Henderson. Since Barcelona is set to undergo a transformation under Koeman, it would be a great opportunity for Mane to embrace a new challenge after having proved himself in England.

The Spanish report has also disclosed that if Mane does choose to depart from Anfield, Liverpool reportedly will not accept any bid less than $142 million for their star winger.

Q: Windows 10 is now five years old. How much longer will Microsoft provide critical updates for it? And what comes next? A Windows operating system thats paid for by monthly subscription fee?

James Labradori, Delafield, Wis.

A: Technology changes fast, but Windows 10 seems likely to be with us for several more years.

One reason is that the coronavirus has kept people isolated from each other, producing a surge of interest in using computers to stay in touch. Microsoft said that trend has also spurred public interest in using Windows 10, causing the company to invest more in the operating system.

Another reason to believe Windows 10 will be with us is that it doesnt have a fixed expiration date as previous versions of Windows did.

For example, it was known years in advance that Windows 7 would stop receiving security updates in January of this year, making it no longer safe to use. But Windows 10 has an expiration date that keeps getting pushed forward: Each major update is supported for 18 months. But the expiration date never arrives because a new version of Windows 10 is automatically installed every six months, restarting the 18-month expiration clock.

In addition, Windows 10 is getting a new cousin called Windows 10X. Microsoft said 10X wont run on PCs. Instead, its intended for stripped-down computers akin to Googles Chromebook.

A Windows 10X computer aimed at the education market would have so little processing power that it would mostly use online software (much as the Chromebook does.)

Another 10X computer intended for the business market would be less capable than a PC, but have enough processing power to run its own software. Experts said some of the technology improvements developed for Windows 10X such as faster updates and protecting the operating system from software crashes may be added to Windows 10.

What does Windows 10X mean for the future? Microsoft has hinted that all Windows computers might eventually run some version of Windows 10X, but it hasnt said when. And the introduction of 10X has been delayed from this fall until sometime next year.

A consumer Windows 10 subscription service (which would replace purchasing the operating system with a monthly fee to use it) has reportedly been discussed within Microsoft.

The idea is that a Windows 10 subscription fee could become part of Microsoft 365, which is currently the online subscription version of Microsoft Office. But subscriptions may not have much appeal to consumers. So far, its estimated that Microsoft 365 is used by fewer than 20% of all Office customers. So, I think Windows 10 users might get a choice of purchasing or subscribing.

Q: I have a model N5110 Dell Inspiron laptop on which I tried to install Windows 10 when support was eliminated for Windows 7. I wiped the hard drive so I could do a fresh installation of Windows 10, but it wouldnt install properly. I later discovered that this PC model isnt compatible with Windows 10. Is there a workaround to make Windows 10 function?

Bruce Johnston, Tamarack, Minn.

A: Dell said your 2011 PC isnt compatible with Windows 10, which was introduced in 2015 (see tinyurl.com/y4zc653x). Theres no workaround for that type of obsolescence; the only way you can get Windows 10 is to buy a new computer.

Windows 10 is five years old, but not going away - Minneapolis Star Tribune

The world is changing and quickly too. As I get closer to my 80s, I cant keep up.

Have you noticed, phone booths are nowhere to be found. They have been replaced with itty bitty phones we can stuff in our pockets.

Everyone, wanting to be different, is becoming more the same as they race to cover their bodies with tattoos.

Folks, not satisfied with the number of body holes they were born with, are drilling new holes into their bodies to hang metal objects from, which makes it increasingly difficult to pass through the airports metal detector.

These are only a few of the changes. Did I mention the blue hair craze?

It had to happen eventually. I, for one, cannot believe it. Borrowing an old idea, Starbucks has come out with what is certain to become the latest popular craze. It may not replace the blue hair craze, but I am confident customers will be clamoring to be first to get in on this hip action. Check out the sign displayed on a Starbucks coffee shop window.

As the sign plainly states, you can order a head and pay for it with the Starbucks app.

One caution. Do not order a head in the state of Idaho. Ordering a head violates the cannibalism law in Idaho. None of the other 49 states have specific cannibalism laws to make ordering a head illegal.

You have to admit, the window sign helps prove I did not make this up.

Hey, wait just a minute. I wonder if I got the sign all wrong. Maybe I read too much into the the sign, order a head. Yea, I wonder if Starbucks is getting into toilet sales.

Another distinct possibility is Starbucks is bringing back a new and improved pay toilet which customers can reserve by ordering a head. You do not need to carry change for the pay toilet because you can pay with your Starbucks app.

It certainly is a sign of the times.

Irelands Kevin OBrien is no stranger to big-hitting exploits but he had cause to regret his batting prowess on Thursday when he smashed his own car window with a trademark six.

OBrien, who scored the fastest century in World Cup history in 2011 to help Ireland chase down a mammoth 327 to secure a famous win over England in Bangalore, made 82 off 37 balls for Leinster Lightning in the Inter-Provincial Twenty20 Trophy.

He hit eight sixes, one of which sailed into the parking lot next to the Pembroke Cricket Club in Dublin to shatter his cars rear window.

After the match, the 36-year-old all-rounder drove the car straight to the garage to get the window replaced.

Dont worry @KevinOBrien113 well get it fixed up as good as new, the dealership said on Twitter. Brien then came up with fitting reply, promising that he would park the car further from next time around.

On Tuesday, news that had long been speculated became official: As first reported by KSRs Matt Jones, DeWayne Peevy, the Deputy Athletic Director at Kentucky, has been named the AD at DePaul. The news had seemingly been in the works for weeks and is now finally official, with Kentucky announcing Peevys departure and DePaul following it up by announcing his arrival.

Admittedly, we dont normally do a lot of transactional, athletic department hirings and firings on this website. But it felt necessary here, if only to explain just how much this guy meant to the University of Kentucky, and its basketball program over the last decade and change. And while Peevy was long overdue to get a job of this magnitude (one he will crush, I have no doubt), its important to explain just how big of a hole he will leave behind at Kentucky.

Understand that Peevy has been at Kentucky for so long, that he actually pre-dates John Calipari by a year. In a world where there are now teenagers who dont remember life in Lexington before Calipari was named head coach, Peevy was on the ground in the wild year of 2008 BC (Before Cal) startingin Billy Gillispies final season as the head coach.

And yeah, if that feels like a lifetime ago, it basically was. Peevys job responsibilities also reflect just how long ago, and just how different Kentucky was at the time. Poor Peevy spent his first year in Lexington trying to drum up any positive media coverage he could for the Kentucky basketball team, in a year when there really was no good news to report. Yes, there was a time not long ago where Kentucky didnt have enough media coverage. Unlike today where it is impossible to keep track of all the newspapers, blogs, podcasts and radio shows who cover the team.

It also means that as Peevy walks out the door, he leaves with a little piece of history with him. He has been there since Day 1 of the Calipari era.

And when I say since Day 1 I mean, the guy was literally there Day 1. When I wrote my book One and Fun some of the best, most vivid stories I got from the entire book centered around Caliparis opening few days as the Kentucky basketball head coach. They were stories that many others had long since forgotten, or simply never took the time to commit to memory. It was Peevy who was there alongside Calipari as he prepared his opening press conference the day he accepted the Kentucky job. It was Peevy who tried to pass along notes, ones that Calipari stubbornly (surprise, surprise) chose not to use.

But it brings me to two important points. One, its that Peevy leaves as basically the unofficial historian of the Calipari era in Lexington. Two, outside of Kentuckys assistant coaches, Peevy quickly became Caliparis most-trusted right hand man at UK.

Really, the best way I can put it is this: You know how John Calipari is just a crazy visionary? A guy who comes up with a million new ideas every year, ranging from Big Blue Madness stuff to schedule quirks, the NBA Combine, on and on and on? Well, if Calipari is the guy throwing a million ideas at the wall, Peevy was the guy who had to execute them all.

When Calipari said I want to beef up the schedule early in his time at Kentucky, Peevy helped create the CBS Sports Classic (an event that Indiana was originally supposed to be a part of, according to Peevy). When Calipari said that he wanted to take his team down to the Bahamas for their once-every-four-years foreign tour, Peevy was the guy who had to call Atlantis and figure out where the team would play, how many hotel rooms theyd need and how to get opposing teams into the country. When Calipari wanted the latest and greatest crazy stunt at Big Blue Madness (think, John Wall dancing in the rafters) Peevy was the guy who worked with UKs operations team to make it happen.

And those are really just examples of things I know about personally. I cant imagine how many other hats he has worn at UK over the past 12 years.

More than anything though, what will be missed most around Lexington is Peevys unique ability to build relations and connect with people. See him at a UK basketball game and the poor guy never got a moment of free time, shaking hands with old friends, chatting with media members, you name it.

That extends beyond just gameday as well, as Peevy was essentially the connective fiber of Caliparis La Familia culture in Lexington. Yes, Calipari is the Godfather, and yes, Calipari is in touch with his former players daily.

But so too is Peevy.

And in the same way those former players inherently trust Calipari they trust Peevy the same. Meaning that if you ever needed John Wall or Jamal Murray or Willie Cauley-Stein for something, Peevy was the guy to go to. He might not be able to get you on the phone with the player that day, but any time Peevy asked one of the guys for a favor, they obliged. It was never a hassle for the player. It was never a wild goose chase where you had to track down the player through a million PR people. If Peevy vouched for you, that was all the players needed to know. Usually you were on the phone with them within a day or two.

Add it all up, and thats really why it is impossible to fully explain what Peevy leaving means to Kentucky basketball. Yes, he had a fancy title of Deputy Athletics Director in Lexington. But thats just a job title. Kentucky will be able to fill the job. But theyll never be able to replace the person theyre losing.

In the end however, what it all boils down to is what I said up top: Kentucky should just be thankful they had him as long as they did.

Hell make a heck of an Athletic Director at DePaul. A job he was long overdue, and way overqualified for.

The vast majority of SARS-CoV-2 transmission occurs indoors, most of it from the inhalation of airborne particles that contain the coronavirus. The best way to prevent the virus from spreading in a home or business would be to simply keep infected people away. But this is hard to do when an estimated 40% of cases are asymptomatic and asymptomatic people can still spread the coronavirus to others.

Masks do a decent job at keeping the virus from spreading into the environment, but if an infected person is inside a building, inevitably some virus will escape into the air.

I am a professor of mechanical engineering at the University of Colorado Boulder. Much of my work has focused on how to control the transmission of airborne infectious diseases indoors, and Ive been asked by my own university, my kids schools and even the Alaska State Legislature for advice on how to make indoor spaces safe during this pandemic.

Once the virus escapes into the air inside a building, you have two options: bring in fresh air from outside or remove the virus from the air inside the building.

The safest indoor space is one that constantly has lots of outside air replacing the stale air inside.

In commercial buildings, outside air is usually pumped in through heating, ventilating and air-conditioning (HVAC) systems. In homes, outside air gets in through open windows and doors, in addition to seeping in through various nooks and crannies.

The latest from the coronavirus outbreak in Colorado:

>> FULL COVERAGE

Simply put, the more fresh, outside air inside a building, the better. Bringing in this air dilutes any contaminant in a building, whether a virus or a something else, and reduces the exposure of anyone inside. Environmental engineers like me quantify how much outside air is getting into a building using a measure called the air exchange rate. This number quantifies the number of times the air inside a building gets replaced with air from outside in an hour.

While the exact rate depends on the number of people and size of the room, most experts consider roughly six air changes an hour to be good for a 10-foot-by-10-foot room with three to four people in it. In a pandemic this should be higher, with one study from 2016 suggesting that an exchange rate of nine times per hour reduced the spread of SARS, MERS and H1N1 in a Hong Kong hospital.

Many buildings in the U.S., especially schools, do not meet recommended ventilation rates. Thankfully, it can be pretty easy to get more outside air into a building. Keeping windows and doors open is a good start. Putting a box fan in a window blowing out can greatly increase air exchange too. In buildings that dont have operable windows, you can change the mechanical ventilation system to increase how much air it is pumping. But in any room, the more people inside, the faster the air should be replaced.

So how do you know if the room youre in has enough air exchange? Its actually a pretty hard number to calculate. But theres an easy-to-measure proxy that can help. Every time you exhale, you release CO2 into the air. Since the coronavirus is most often spread by breathing, coughing or talking, you can use CO2 levels to see if the room is filling up with potentially infectious exhalations. The CO2 level lets you estimate if enough fresh outside air is getting in.

Outdoors, CO2 levels are just above 400 parts per million (ppm). A well ventilated room will have around 800 ppm of CO2. Any higher than that and it is a sign the room might need more ventilation.

READ: Colorado Sun opinion columnists.

Last year, researchers in Taiwan reported on the effect of ventilation on a tuberculosis outbreak at Taipei University. Many of the rooms in the school were underventilated and had CO2 levels above 3,000 ppm. When engineers improved air circulation and got CO2 levels under 600 ppm, the outbreak completely stopped. According to the research, the increase in ventilation was responsible for 97% of the decrease in transmission.

Since the coronavirus is spread through the air, higher CO2 levels in a room likely mean there is a higher chance of transmission if an infected person is inside. Based on the study above, I recommend trying to keep the CO2 levels below 600 ppm. You can buy good CO2 meters for around $100 online; just make sure that they are accurate to within 50 ppm.

If you are in a room that cant get enough outside air for dilution, consider an air cleaner, also commonly called air purifiers. These machines remove particles from the air, usually using a filter made of tightly woven fibers. They can capture particles containing bacteria and viruses and can help reduce disease transmission.

The U.S. Environmental Protection Agency says that air cleaners can do this for the coronavirus, but not all air cleaners are equal. Before you go out and buy one, there are few things to keep in mind.

The first thing to consider is how effective an air cleaners filter is. Your best option is a cleaner that uses a high-efficiency particulate air (HEPA) filter, as these remove more than 99.97% of all particle sizes.

The second thing to consider is how powerful the cleaner is. The bigger the room or the more people in it the more air needs to be cleaned. I worked with some colleagues at Harvard to put together a tool to help teachers and schools determine how powerful of an air cleaner you need for different classroom sizes.

The last thing to consider is the validity of the claims made by the company producing the air cleaner.

The Association of Home Appliance Manufacturers certifies air cleaners, so the AHAM Verifide seal is a good place to start. Additionally, the California Air Resources Board has a list of air cleaners that are certified as safe and effective, though not all of them use HEPA filters.

Both the World Health Organization and U.S. Centers for Disease Control and Prevention say that poor ventilation increases the risk of transmitting the coronavirus.

If you are in control of your indoor environment, make sure you are getting enough fresh air from outside circulating into the building. A CO2 monitor can help give you a clue if there is enough ventilation, and if CO2 levels start going up, open some windows and take a break outside. If you cant get enough fresh air into a room, an air cleaner might be a good idea. If you do get an air cleaner, be aware that they dont remove CO2, so even though the air might be safer, CO2 levels could still be high in the room.

If you walk into a building and it feels hot, stuffy and crowded, chances are that there is not enough ventilation. Turn around and leave.

By paying attention to air circulation and filtration, improving them where you can and staying away from places where you cant, you can add another powerful tool to your anti-coronavirus toolkit.
