New Orleans Above Ground Cemetery

Masonic cemetery

There is an old joke in New Orleans that you know you are from New Orleans when you worry about your late relatives coming to visit you when it floods. The joke of course being based on the fact that most cemeteries in New Orleans are above ground where human remains are buried in stone crypts and mausoleums. The water table is too high for remains to be buried six feet under. While some of the plots are rather simple, many of the crypts are quite beautiful and ornate. All of these photos were taken at Masonic Cemetery, where many of my relatives are buried. Some more information about and photos of Masonic Cemetery can be found here. Masonic Cemetery has some large tombs that hold numerous people related by professional or social organizations. Such as this large Masonic tomb, which has an usual staircase to its roof.

However most of the tombs are owned by families. They can be quite ornate.

Some of the tombs list the family name on top.

Gould tombThen list most or all of the family members buried inside.

Gould namesOthers list only the name of the family or of one person buried inside. The one below lists one person buried inside, A.F. Parmalee but the stone vase on top says “Mother”, so probably A.F. Parmalee’s wife is buried inside with him, and their children put the vase their to honor their mother.

Female Restroom Design Basics for Men

I am officially fed up with going into restrooms that have been obviously designed by men. Evidently the women of the world are going to need to take more drastic actions because this situation does not seem to be resolving itself as more women enter engineering, architecture, and construction. Building code covers a whole range of issues from structural to safety to just plain standardization. Clearly, proper female restroom design needs to be put into building code. Perhaps we also need a rule that just as all engineering designs must be certified by a Professional Engineer, all female restrooms deigns must be certified by a female, perhaps not a female engineer, but probably any female who has ever used a public restroom will do.

Men, yes I am aiming this post at men because honestly I find it very hard to believe that a woman would be capable of making such stupid design decisions for female restrooms. This is not to say a female is smarter than a male (that’s an argument for another day), but because any female who has used a public restrooms knows exactly that I am talking about and would not design it so stupidly. So men, I don’t know why you are so confused about what about what we do and don’t need in a restroom. I assume and hope that none of you have been in a restroom when the ladies are using it, but still I would think the things that we need and want would be pretty common sense. Perhaps I should not assume certain men to have common sense when it comes to the ladies though. This election season has taught me that there are men out there who think women have magical reproductive systems. Thus ladies, lady parts, and lady part business is clearly an utter mystery to some segment of the male population. Therefore, let me give you an education about what the ladies want and don’t want in a restroom. I promise there will be no discussion the lady parts of anything else that might make you squeamish.

  1. Probably the biggest complaint that I and many other women have is the length of the stalls. Here is how it is fellas, ladies like to do their business in stalls. We don’t use the urinals. Not only do we like to use stalls, but we like to have doors on said stalls to give us some privacy. No problem, you say, we always give you stalls with doors. Well, yes, you do, but here’s the thing, evidently you have never used a toilet in a stall with a door because if you had, then you would understand that the stall needs to be long enough that we can close the dang door without standing on the toilet or straddling the toilet. Seriously, the stall should be long enough that we can stand in front of the toilet and close the door at the same time. If you can’t imagine what I am talking about, I invite you to go to nearest toilet and stand in front of it, facing away from it (like you might sit down or something on it). Now look at the distance your body takes up in front of the toilet. We need at least that much space between the toilet and the swing area of the door. Since the swing area of the door is put onto building plans, you already know that distance, so just add a proper distance between the toilet and swing area so that you can stand there. Simple right? Makes sense?
  2. We need a coat hook or something like it on the back or the door or the side of the stall. You might be aware that many women carry purses. Sometimes we also carry jackets or backpacks or other items. We like to be able to hang them when we are in the stall, so we don’t have to put our stuff on the floor. See this stuff is really not complicated.
  3. We need a small trash can inside each and every stall. Some restrooms have those neat trash can and toilet roll hangers that fit in the wall between two stalls. Those are just fine, just as long every stall has a trash can that can be reached from the privacy of that stall. I realize you may be confused as to why on earth we would need a trash can in each stall. Let me just say that at certain times of the month, we need to carry certain, shall we say feminine hygiene products, into the stall, and we like to dispose of, shall we say used feminine hygiene products, in the privacy of the stall. If you want further information please go ask your wife, mother, middle school health teacher, or the internet.
  4. While I am sure it is obvious that the stall needs to have toilet paper in it, what does not always seem to be obvious is where to put it. To put it simply, 99.999% of women are not in fact contortionists, and I imagine even the 0.001% of women who are, don’t like to do contortions in order to reach the toilet paper. It should not hitting our leg. It should not be behind the toilet. It should be in an easy to reach location.
  5. One more thing about the stalls. I can only presume that someone somewhere at some point created some calculation as to how many stalls would be necessary based on the planned traffic in the bathroom based on the design occupancy of the building. Whoever they were that came up with this calculation, they were wrong. I don’t care how smart they were and what kind of glorious calculus and statistics they used. They were wrong. If you don’t believe me, I invite you to go stand outside any women’s restroom at any sports or performing arts venue, airport, dance club, or any other place where you can find large groups of women. There will be a line. However outside the men’s room, there will be no line, or there will be a line 1/10 the size of the women’s room line. So whatever your calculation says, throw in a large safety factor, maybe upwards of 1.5. We will call it the female safety factor. It is a safety factor both from the traditional engineering standpoint of being conservative in design but also from the standpoint of you may be in danger if us females find out who is responsible for these horrible restroom designs that never seem to improve.
  6. Enough talk about the stalls, now let’s discuss the sinks. In general, the time spent in the stall is the time limiting step in a women’s use of the restroom, so there does not need to be as many sinks as the stalls. However there should be an adequate number of sinks, and they should be placed such that traffic can easily flow to, away, and around them.
  7. Staying with the sinks, optimally there should be one soap dispenser per sink, however, if needed, this number can be reduced to as low as one dispenser per two sinks, if and only if, the dispenser if placed between the two sinks that share it. I’ve been to too many restrooms where there were three sinks and two soap dispensers at either end. Let’s think about this. Where the heck is the person using the middle sink supposed to get her soap. While I suppose some people may wash their hands differently, I and everyone I know, wets their hands, then puts soap on their hands, lathers, then washes with water. If the soap is not near the sink, are we supposed to get the hands wet, walk around someone else, get soap, and return to our sink, all while dripping water from our wet hands? Common sense. That is is that is really needed here. Also, if the reason for this stupidity in restroom design is due to restroom designers not being the type that wash their hands after the restroom, then gross, and wash your dang hands.
  8. Now that we have cleaned our hands, we need to dry them. Shocker. Similar to the sink discussion, there should be enough paper towel dispensers or hot air dryers, to keep traffic moving in the restroom. I don’t know the optimal number, but if there are ten sinks, then more than two towel dispensers would be a good idea.
  9. Next, we are back to trash cans. Yes, I know, I already stated that we need trash cans in each stall, but we also need them outside the stalls. After we use paper towels to dry are hands, we need to throw the used towels away. This is where the trash can comes in. Sometimes, we have something else we might like to throw away, who knows, so trash cans are good. Also, to get into more detail, big trash cans are good, and trash cans that we don’t have to touch to open are really necessary for hygiene reasons.
  10. The next item that is necessary is a baby changing area. However, I am not sexist; the men’s restroom should have this too. Daddies change diapers too nowadays. A space specially dedicated for changing babies is required.
  11. Now let’s discuss furniture. We don’t need it. I don’t know what you fellas think we do in restrooms, but in general, we do our business, wash our hands, and get out. Sometimes, a lady might want to freshen her makeup or do other personal tasks. Sometimes, if we are with a friend, we might chat. In general though, we don’t use the restroom as a living room. We don’t need couches. We don’t get the vapors and need to use the restroom to have a lie down. However we keep finding restrooms with couches in them. My theory is that the couches are there because the restroom is being used as a storage location for the couch. Look if the restroom is huge, then fine put a couch there, and if some women has a use for it, she can use it. However if the restroom is huge, go poll all the women you know, most of us would vote for more stalls, not a couch. [See number 5]
  12. Are you ready for advanced restroom design? I know you can handle it. For hygiene reasons, after you wash your hands, you should touch as little as possible. That is why some of the newer restrooms don’t have doors at the entrance, they just have a slightly torturous route from the opening to the restroom to provide privacy. These are great. If this is not possible, consider placing a trash can right by the door, that way we can open the door with a paper towel, then throw it away afterwards. Simple.

Edited to add the following three based on comments from others:

  1. No pedestal sinks. They are pretty and all, but just as we have stuff to bring into the stalls, we will still have that same stuff when we leave the stalls. Where do we put said stuff if there are no counters?
  2. Consider that humans are different heights. While toilets and sinks normally are at generally standard heights that does not always accommodate everyone, there is flexibility in the height of paper towel dispensers, hand dryers, mirrors, and a few other items. Try putting them at different heights, so short people can use the lower ones, and taller people can use the higher ones.
  3. I have been informed from a couple of males, that I may have assumed too much when I said the bad female restroom design reflects ignorance or unthinking on the part of men. I stand by my statement that the problem is probably men because statistically speaking most engineers, architects, and contractors are men. However, I have been informed by men that male’s restrooms have just as bad design as the female’s restroom. I have also been informed that there are bad design of urinals. I know nothing about urinals, so I will not comment on how to improve them, other than to say that improved fluid dynamics design may be needed.

This has been your basic introduction to proper female restroom design. Please consider it carefully because if not, we are going start coming after those responsible for bad female restroom design. You have been warned. Women, was there anything I forgot? Please feel free to add to this in the comments. For further amusing discussion on what both women and men want in a restroom, please see this Storify Twitter discussion.

A heart tugging, scientific exhibit

At the Smithsonian’s National Museum of Natural History is, in my opinion, one of the most moving scientific exhibits I have ever seen. Yes, I am a softie, especially when it comes to animals, but this exhibit almost brought me to tears. It is an exhibit of two skeletons, a man and an extremely large dog, but not just any man and dog. The human skeleton is Dr. Grover Krantz, a professor of physical anthropology at Washington State University, and the dog is his Irish wolfhound Clyde. While the skeletons have scientific value, the fact that Dr. Krantz wanted his remains used for his scientific field after death is a wonderful testament to his love of his chosen scientific field. The fact that Dr. Krantz wanted to be immortalized with his beloved dog is what almost brought me to tears. Rest in peace, Dr. Krantz and Clyde. I’m sure you are both happily together in heaven.

Dr. Krantz and Clyde

The sign accompanying the exhibit is below, and I have quoted the text below it.

Dr. Krantz exhibit sign

Dr. Grover Krantz, a professor of physical anthropology at Washington State University, generously left his remains and those of his beloved 160-lb (72.6-kg) Irish wolfhound Clyde to the Smithsonian’s National Museum of Natural History.

At his death in 2002, according to his wishes, Dr. Krantz’s remains were taken to the University of Tennessee’s Anthropology Research Facility, where scientists are conducting many kinds of skeletal research, including studies of soft-tissue decay rates — information that is essential in forensic cases for accurately estimating time since death. In 2003, Grover and Clyde were brought to the museum, so that their skeletons could be used in teaching. Posed here as in life, their skeletons help our scientists teach human and nonhuman skeletal anatomy in relation to biomechanical function.

This exhibit honors Dr.Krantz’s expressed wish to be on display, and his dedication to education and his chosen scientific field.

Flight from Las Vegas

The flight path between Las Vegas and southeastern airports such as Dallas passes over some really pretty terrain and landmarks. Flying into Las Vegas I was lucky enough to get some really good photos of the Grand Canyon. For several reasons, on the flight leaving Las Vegas, I did not as good photos of the Grand Canyon, but I did get a few interesting photos. Immediately after taking off, I got some neat photos of the Las Vegas Strip.

Then the Hoover Dam.

This is part of Lake Mead. I am fairly sure it is part of what is called the Grand Wash Bay.

Then a few photos of the Grand Canyon.

Finally this canyon that is east of the Grand Canyon, and I am not sure if it is technically part of the Grand Canyon.

Las Vegas Wash Wildlife

Previously I posted photos of the scenery along the Las Vegas Wash. The Las Vegas Wash attracts a lot of wildlife, particularly birds, because it is an important source of water. Below are photos of some of the wildlife I saw on it.

First the small wildlife. A pretty lady bug.

I have no idea what this is.

A spider.

There was a lot of birds. Bunches of American coots.

I think these are male Gambel’s quail.

I think this is a Gambel’s quail and a Crissal thrasher (its curved bill is more evident in another photo).

Black phoebe

Male northern flicker

The following three photos are of the same bird. I think it is a juvenile northern harrier, but I would really like someone to confirm that or tell me what it is.

Of course what body of water would be complete without fish. This fish had lovely orange lips.

Las Vegas Wash

I don’t know about anyone else, but when I think of Las Vegas, I think of the Strip, casinos, shows, and desert. The only wildlife I think of is that of the human variety, generally in an inebriated form. Thus, on my recent trip to Las Vegas, I was surprised to learn about the Las Vegas Wash. It is the lowest part of the valley in which the Las Vegas metropolitan area sits. All storm water and urban runoff in the area drains to it, and it eventually drains to Lake Mead. The Wash has been increasingly eroded due to the increased flow into it from the increased Las Vegas metropolitan area urban runoff. In the past decade or so, the LVWCC has constructed numerous structures to reduce erosion in the Wash and increase the wetlands in it. Structures such as this.

And this weir.

They have also been removing non-native plants and planting native plants. None of which I can identify in the photos below.

Plants that can amazingly grow in the desert that is Las Vegas.

All of this has created a very pretty area, which is really nice to hike along, assuming the weather is nice. It has some lovely views of the nearby mountains.

And beautiful sunsets.

In some places, it allows some nice views of the Las Vegas Strip.

Next time you are in Las Vegas, if you like the outdoors and want to get away from the Strip, I highly recommend checking the Las Vegas Wash out. In a later post, I will be posting photos of the wildlife I saw on it.

 

Industrial Waste Site Tour

I recently toured an industrial waste site where the groundwater underneath is being remediated for perchlorate contamination as well as other contaminates. Perchlorate can be naturally occurring, but in this case it is from historic rocket fuel and explosives manufacturing. The groundwater is being remediated partially through the use of bioremediation (i.e. microbes).

Lots of chemicals on site for the remediation, like ferrous sulfate.

Hydrogen peroxide

Nutrient for the microbes.

Lots of nutrients for the microbes

The label on this container notes the dangers of the concentrated phosphoric acid, which it contains. It also notes that there is a $800 deposit on the container, so you definitely want to remember to return the container.

The main part of the site is a series of fluidized bed reaction tanks.

With centrifugal pumps to keep the fluids moving.

More chemical storage tanks

At industrial plants, pipes always need to be labeled.

The first two mailboxes are labeled “PAP Sample to Lab,” and the second two are labeled “Clean Bottle Return.” I actually have doubts that these are really being used for pick up of samples to go to the lab. In general, samples need to be refrigerated once taken, and they should not be left in a metal box to bake in the hot sun.

Finally, always remember to drive slowly

Las Vegas, Where Insane Architecture Reigns

A disclaimer on this post: I am an engineer. Architects and engineers famously don’t get along all that well. Oh sure, we work on projects together, but engineers understand and respect the laws of physics. Architects, not so much. I do in fact like and respect architects, and at one point in high school, I wanted to be one. That was until I realized how much more I like and was better at the math and science of design than the art of it. However I do appreciate good architectural design. Then there is Las Vegas. I need to study the history of Las Vegas because I am really curious when and why casinos started being built with crazier and crazier, over the top themes. The casinos really know how to do a theme also. They completely saturate the property with the theme, whatever it may be. I have to wonder if drugs were involved in the design of some of the casinos. Along the Strip, are casinos and hotels with themes based on at least three different continents, several different time eras, and both real and fictional places. Part of what I find so hilarious is that casinos with completely different themes sit right next to each other. For example, on the southern end of the strip is Mandalay Bay which has water as part of its theme and features an aquarium. Thus it is appropriate (in Las Vegas logic) that next to it is the Luxor, which is themed off of ancient Egypt (i.e. the desert) and features a giant, black glass pyramid, a shape, I might add which is rather inefficient use of space for a hotel. Also, I can’t leave out the fake Sphinx in front of it because of course a pyramid is not complete without a sphinx.

The Luxor sits hilariously next to the Excalibur, so that one can walk from ancient Egypt to the fictionally old England of Camelot.

I must say that while the Excalibur does a nice, over the top, job of a theme based on the fictional England of the Camelot tales, it really does not have a proper moat, and that is a disappointment.

From fictional England, one can then walk to modern day New York City because well, why not?

Across the street from New York New York is the MGM Grand, whose theme I have never been clear on, but it features a giant gold lion head in front. If the MGM Grand lion and the Luxor’s sphinx came to life, would they be friends or enemies? Would they eat the giant M&Ms and drink the giant margarita and coke that sit next to the MGM Grand in what appears to be food trademark central?

Very close to all the gaudiness and insanity is the brand new CityCenter, which features some absolutely gorgeous buildings and in my opinion, looks rather out of place on the Strip.

At the front of CityCenter is the Crystals at CityCenter designed by Daniel Libeskind in his trademark disjointed, angled buildings design. I am rather a fan of Daniel Libeskind. He and Frank Gehry are probably my favorite modern architects, but I could never work on the construction of any of their buildings because first, I’m not that type of engineer, and second because they seem to enjoy designing buildings that try to break the laws of physics.

The Crystals is even interesting up close due to the different materials and textures on the exterior.

Inside the Crystals is more insane architecture. I have no idea what this wooden structure is supposed to be.

Across the street from CityCenter is Planet Hollywood and the Miracle Mile Shops, whose architecture is not really insane, just rather loud. The exterior of the Miracle Mile Shops features a series of three-dimensional dots that look either green or purple depending on the direction from which they are viewed. I have no idea what they are supposed to represent, but they are kind of cool.

Next to Planet Hollywood, we again travel to another continent with Paris which features a scale model of the Eiffel Tower because again, why not?

At this point on the strip, you can look at a scantly clad women from Bally’s who appears to be looking at Paris, perhaps to get some much needed clothes for which Paris is famous. Across the street is the edge of ancient Rome (Ceasar’s Palace), modern (?) Italy (Bellagio), and the modern architecture of CityCenter. Only in Las Vegas.

The Strip is not done yet though. Across from ancient Rome is the Flamingo, which is not all that outrageous, but just features lots of pink flamingos that would never be found in Nevada. Then the Asian themed Imperial Palace, which appears to be coming down or being renovated. Asia is next to the New Orleans’s Mardi Gras themed Harrah’s. Close to this, we go back to Italy with the Venetian and Palazzo. Italy is very popular on the Strip.

Across the street from fake Venice is the Mirage with its waterfall that at night has a volcano on top of it. Again, why not?

In the background is Treasure Island which of course has pirates. Don’t most deserts have pirates? Oh wait. . . Then slightly further down the strip is the Fashion Show Mall which appears to just be a mall, but a UFO landed on top it. No doubt the UFO got lost from nearby Area 51. Further down from it is the Stratosphere which features a roller coaster on top of a really tall tower because isn’t that where most people put their roller coasters?

Well north of the Strip are the really old casinos of Fremont Street. Several years back, they built the Fremont Street Experience, a light structure to help bring business back to their area and away from the Strip. From an engineering standpoint, the Fremont Street Experience is a cool structure.

One of the fun things about the Fremont Street Experience is that it is a light show that encapsulates other lighted advertisement signs.

I have to wonder how much electricity would be saved if all of Las Vegas’s lights were converted to LEDs. At the east end of the Fremont Street Experience is Fremont East. I have no idea what is in this district, but it features a fun, retro martini sign. Presumably there are bars there, but I think that goes without saying.

So that was my one cent tour of the insane architecture of Las Vegas. I hope you enjoyed the visit. I did.

 

Hoover Dam and Bypass Bridge

On my recent trip to Las Vegas, I made a trip out to Hoover Dam. As an engineer, I have an irresistible urge to visit important engineering landmarks. However, I don’t think you have to be an engineer to realize what a marvel the Hoover Dam is. Too many hardworking men died building it (one is too many though), and it has caused ecological problems by altering the flow of the Colorado River. However from an engineering stand point, it is an absolute marvel. The new bypass bridge next to it, more formally known as the Mike O’Callaghan – Pat Tillman Memorial Bridge, is in my opinion also a marvel and beautiful in its design. Part of the reason I consider both the dam and bridge to be marvels is where they were built, across the very steep, deep canyon of the Colorado River. The Hoover Dam was built with some really nice details that I have to wonder if most visitors appreciate or even notice. It was not just built as a plain hunk of concrete, especially on top where visitors walk. The bypass bridge was also built with some nice details, including many education plaques explaining how the bridge was built and why.

On a basic level, the Hoover Dam is a large block on concrete, carefully poured to hold back the Colorado River, and its adjoining power plant.

Actually, it is not a large block of concrete. It is a massive structure of carefully and individually poured blocks of concrete that form one connected structure.

It has its four connected intake towers to bring the water to the power plant. The intake towers were nicely designed in an art deco style.

Lake Mead water level has been dropping, so currently the Arizona overflow spillway is entirely out of the water.

A plaque on the dam marks the state line between Nevada and Arizona and notes that the American Society of Civil Engineers has selected the Hoover Dam as one of seven modern civil engineering wonders.

On top of the dam are restrooms. Here is the women’s restroom which has quite the entrance.

Here is the floor of the women’s restroom. Presumably the men’s restroom has a nice one too, but I wouldn’t know.

The designers really liked brass doors. I am not sure where this brass door leads since you can longer enter the dam the way the way you could when it was originally built.

If you stand in front of the door at the right angle, at the right time of day, with the right sunlight, you can see the intake tower on the other side of the dam reflected in the door. Look near the top of the door, and you can see the reflection of the blue clock near the top of the intake tower.

An upclose photo of the post top in front of the door in the above photo. They put brass prickly pear cactuses on top of the posts. I love that level of detail.

In the reflection of this door’s window, you can see Lake Mead.

I don’t actually know what this is, but it is on top of the dam. I thought it was kind of interesting, and also it has the name of another state besides Nevada and Arizona on top of the dam.

At the bottom of the dam, of course, is its power plant. Below, as seen from dam.

The view from the bridge of the power plant.

The power plant requires a jungle of transmission lines.

The relatively new visitor’s center, new compared to the dam, was also built in a ridiculous position on the shear canyon walls.

The bypass bridge sits high above the power plant.

It gracefully crosses the canyon.

The pedestrian walkway of the bridge has nice markers to denote the state line and apex of the bridge, which are in two different spots.

 

 

 

 

 

The path to the bridge passes through a rock cut where each side is lined with rock stabilization bolts, which I personally think are really cool looking.

Finally, one last look at the Hoover Dam with the shadow of the bridge across it, and the moon rising in the sky.
