MrsDrPoe: Date Night Surprise

Last Saturday night, Mr. Poe and I went out for dinner. We had originally planned on going to Logan's Roadhouse (because I had a B1G1 Free coupon); however, we realized after setting out that the closest steak place to us is LongHorn- not Logan's. Although we didn't have a coupon, we decided to go to LongHorn anyway...

The food was amazing! The steaks were perfectly cooked, the service was wonderful, and since we had just moved and it was our first time to Longhorn, the manager gave us free desert:


It was a fantastic experience, and we would definitely recommend LongHorn to anyone looking for a nice dinner out. We have decided that this will be our new "specially occasion place"...and we have an anniversary coming up...yum!

Mr2Poe: Raising Monsters

So you're thinking of getting a Great Dane?


Just some things to consider... It will make huge messes until potty trained. It will cost more money at the beginning for shots and vet visits than smaller dogs. (Most medicines, including heart worm medication, are dosed by the pound. If you get a female for example, I think we paid $250 to get her fixed at around 5 months old.) It will need to be properly trained and trained early. (I spent a lot of time with Layla in order for her to consistently obey commands.) If the dog is too big to control physically, then it is extremely difficult to teach basic "dog etiquette". It needs to learn to behave on a leash early. This is especially important for smaller owners. (We had this problem, but now Mrs. Poe can walk her without issue.)

While these negative aspects exist, don't let them scare you away.
I will tell you that I will own a Dane for the rest of my life, Lord willing. She is the most loyal, obedient, friendly, and beautiful dog I have ever seen (I'm not biased at all). She is great with kids, other dogs, and even crabby adults. While training, she was not overly obstinate, and learned very quickly. She is so gentle and sweet, and she gives great hugs - it's just like a big hairy person. That is probably my wife's favorite part of owning Layla. I would definitely recommend purchasing or rescuing a Monster Dog.

Here are some tips that we found useful when raising our Dane:

Ground Rules
-No Danes on furniture
-No Danes on beds
-No Dane mouthing (She can put your whole hand in her mouth)
-No unauthorized Dane barking (it's loud)

These rules were beneficial for several reasons. We wanted a people friendly environment, and most people aren't used to really large dogs. This keeps Layla from thinking she is everyone's lap dog, and makes our house an inviting place to visit, even to those who aren't dog lovers like us.

Training
-After shots, it is best to socialize him/her with other dogs
----Danes can have dominance issues with other dogs
----This is more prominent with males
-
Crate training our Dane made it easier
----Provides a "comfort zone" for him/her when frightened
----Allows you to get them out of the way when a problem arises
--------Dealing with broken glass, etc.
--------Dealing with children's messes
----Helps with potty training (they won't potty in their crate)
-Potty training
----Take out as soon as they exit the crate
----Use a leash at first (even in a yard)
--------You can keep them from wandering
--------He/she realizes the purpose for going outside
----Use a "key word" (like potty)
----Begin by taking him/her to the same spot
----Keep to a schedule
-Using a baby gate when a Dane is small will teach them
-boundaries even when they are older (baby elephant syndrome)




Food
-We prefer large/giant breed Iams brand food.
----Didn't hurt her stomach
----Easily available
---
-First ingredient was chicken
----Plenty of calcium; no supplement needed
----Mid-level pricing; coupons available
--------More expensive food could reducing gas, waste size
--------Less expensive food has byproducts and fillers

-Don't feed too much protein; 26% in Iams worked well for us
-Don't over feed
-Keep to a schedule
-Don't exercise him/her 30min before or after you feed
-Dane's are lazy
----Don't require food intake of high-energy dogs
----Layla eats 40lbs of food every 3-3.5 weeks


Exercise
-Don't over exercise
----Great Danes are well known for having hip issues
----Heart failure from over exhaustion can occur
-Danes don't do well in extreme hot and cold
----Not having an undercoat makes it difficult to regulate temp.

MrsDrPoe: "With Great Power Comes Great Responsibility"

Good morning, all! This Theology Thursday, I invite you all to open up your Bibles with me as we look at the topic of pointing others to Christ.

Early last Sunday evening, a visiting preacher from Ireland was informing the congregation on how the small group that he works with evangelizes. Two of the three prongs to their three pronged approach were to hand out New Testaments and to place an add in the local papers inviting folks to study the Bible. This brother pointed out that these methods of sharing the gospel with others are not difficult, highly technical, or terribly expensive. He also, very humbly, stated that he sometimes doesn't know answers to questions addressed to him in Bible study and that he readily admits it when this is the case. He encouraged us to do the same and suggested further research on our part to help supply the person with an answer.

That discussion made me think about the fact that no one knows everything, but everyone knows something. And it's what we do with what we know that defines who we are. If you were a doctor and one of your patients had a condition that would kill them in the next two years without treatment, would you tell them? If you were an airplane mechanic and you knew one of the planes that you work on wouldn't survive another flight without being overhauled, would you tell your supervisor? Now you may be saying, "Of course I would! I don't want to get sued!"
or "Sure! I could go to jail for negligence or manslaughter!" or "Yes! I don't want anyone's death on my hands!" or even "Duh! It's my job!"

Think about that for a minute. People around us are dying spiritually every day- our neighbors, our friends, our families...as Christians we know that. We also know the ONLY thing that can save them! "For I am not ashamed of the gospel of Christ, for it is the power of God to salvation for everyone who believes, for the Jew first and also for the Greek." (Rom 1:16) It is our job to teach others: "Preach the word! Be ready in season and out of season. Convince, rebuke, exhort, with all longsuffering and teaching." (2 Tim 4:2) Furthermore, we have been given the scriptures from God, and in order to be good stewards of this blessing, we must share it with others.


Mini Case Study: Apollos
In Acts 18:24-28, we are introduced to a man named Apollos. He is described as "an eloquent man and mighty in the Scriptures;" furthermore, we are also told that he "had been instructed in the way of the Lord; and being fervent in spirit, he spoke and taught accurately the things of the Lord." But, the scriptures also point out that he "only knew the baptism of John [the Baptist]." By this time, the One that John the Baptist was preparing the way for had already come, died on the cross, and ascended into heaven; thus, as this passage indicates, Apollos' knowledge of the plan of God for salvation is limited.

Instead of waiting till he knew 'everything,' he was preaching the word at the synagogue in Ephesus. Of course, Aquila and Priscilla (after hearing him) took him aside and "explained to him the way of God more accurately." Later, we see Apollos taking his heightened knowledge and using it to continue to "vigorously [refute] the Jews publicly, showing from the Scripture that Jesus is the Christ."


We can never know everything about the Bible; therefore, we should diligently continue to read and study throughout our entire physical lives. But the fact that our knowledge is limited should not keep us from telling people about the word...about Christ and how he died for us and for them. We may not have all the answers to all the questions that might be asked of us, but we can try to find someone who does when these questions arise. We have the word, and the word is power, and "with great power comes great responsibility."

MrsDrPoe: The Best Coleslaw EVER

"What's for dinner" this Wednesday night actually should be termed "what's with dinner." I got this recipe from my sister, Mrs. Luke (who found it somewhere...), and it is seriously THE best slaw I have ever eaten. And it just so happens that it pairs very well with pulled pork.


Ingredients: 1 medium cabbage, 2 medium carrots, 1 green pepper, 2 Tbs grated onion, 1.5 cups sugar (not pictured), 2 cups mayo, 1-2 Tbs celery seed, 1 tsp salt (not pictured), 1/8 tsp pepper (not pictured), 1/4 cup dijon mustard, 1/4 cup vinegar.


Using a large food processor, shred the cabbage, carrots, and pepper into small pieces. Empty the pieces into a large bowl or plastic container. Note: this may be easiest if shredded in batches, depending on how big your machine is and how much cabbage you have.


Mix the remaining ingredients together in a medium mixing bowl to make the dressing. Note: this dressing could also be used with a store-bought bag of shredded cabbage.


Pour the dressing over the shredded veggies and stir to coat. Enjoy!

MrsDrPoe: Hopeful Parenting

Good morning all! Today for my latest reading review, I present to you...David Jeremiah's "Hopeful Parenting: Encouragement for Raising Kids Who Love God":


Let me being the review by stating that as far as we know, Mr. Poe and I are NOT currently pregnant. I picked this book up (for 70% off) shopping with Mama Poe while the menfolk were painting the truck. Mr. Poe and I have raised some decent fuzzy-children (if I do say so myself), but we have no experience with non-fuzzy-babies...you know, the kind with souls. In light of that fact, I am slowly trying to read up on the subject.

"Hopeful Parenting" is an easy read full of encouragement and advice on raising godly children. I greatly appreciated the fact that Mr. Jeremiah includes some suggestions for showing love to our children, helping our boys become "courageous Daniels" and helping our girls become "faith-filled Esthers," among other things. I have found that too often books with the word "encouragement" in the title lack substance, filling the pages with fluffy, repetitive, feel-good stories.

This book emphasizes both the blessings and challenges of being a parent. It also enforces how a parent's behavior influences a child and that a solid, Christ-centered marriage greatly aids in the construction of a godly home. The reading of "Hopeful Parenting" helped to renew my desire to grow in love for God and in knowledge of His word- it reminded me that not only is this growth, this seeking pleasing to the Lord, but it also can have an impact on the spiritual lives of those around us (like our children).

I have two negative comments about the work. First is the information in the chapter on the benefits on having a Christian home. I felt like this chapter emphasized worldly things (health, wealth, instilling responsibility, long-life, perpetuation of traditions) more than it emphasized spiritual things (pleasing God, adding more servants to His kingdom, etc.)

The second is that some of the views expressed in the book are not in accordance with my understanding of what the Bible teaches (not that my understanding is perfect). With that in mind, I would like to make the typical disclaimer about any books I read related to any aspect of Christianity - they should be read with an open Bible (God's instruction manual for living godly lives and raising godly families) and should not be set above or equal to scripture.


Do you have any parenting book suggestions?

MrsDrPoe: "Control, Control! You must learn control [volumes]!"

Happy Thesis Tuesday to you all! Last week, we briefly mentioned control volumes; this concept is crucial to correctly applying fluid mechanics equations to a particular problem. Thus, borrowing a line from Yoda, "You must learn control [volumes]!"

Tips for CV Selection
Selection of a control volume is easy; however, selection of the best control volume can be a bit more difficult and often takes practice. Here are some helpful tips:

1) make sure the points in the flow that you have information for (velocity, pressure, temperature, etc.) are located on the control surface

2) making the control surface perpendicular to the flow often makes problems easier to solve

3) if you are looking for some support force of a beam or stand, the control volume should intersect the beam or stand

4) for internal flow, the pipe that fluid is flowing through is often not included in the control volume when the "no-slip" condition is applied to the pipe surface

Moving or Deforming CVs
We know that fluid is allowed to flow across the control surface (i.e. into and out of the control volume), but in many cases (looking at jet engines, deflating balloons, etc.) employing a control volume that moves or deforms relieves some of the difficulty in finding a solution.

Today we will focus primarily on moving CVs. First, it is important to note that the shape, size and orientation do not change for a moving control volume- the volume is simply linearly or angularly translated with some velocity Vcv. One of the major differences between moving and stationary control volumes is that the the velocity with which the fluid crosses the control surface is a relative velocity (W) for a moving CV and an absolute velocity (V) for a stationary one.
(The relative velocity is what we will use later in the continuity equation involving a moving control volume.) To obtain the absolute velocity of the fluid at the control surface, the relative velocity must be added to the velocity of the control volume:

V = Vcv + W

As a quick example to get these differences in velocity cemented in your minds, let's consider a man, John, entering a train car at 0.1 m/s while the train itself is traveling at 160 m/s. If we draw the control volume around the train car that John is moving through, the velocity of the CV is 160 m/s. The 0.1 m/s velocity is John's relative velocity; it is such because that is what a person sitting in the train car would measure his velocity as. A person sitting on a station platform outside the train car would measure his velocity as his absolute velocity, which would be 160.1 m/s.


Control volumes can be a bit daunting, but the more you deal with fluid mechanics problems, the easier it is to determine what type of CV you should use and where you should place it. Never fear! We'll soon get into some interesting applications of these concepts. Until next week...may the force be with you!

MrsDrPoe: A Beginners Guide to Couponing, Part 6

Although there is one more major drug store that we have yet to discuss (Rite Aid), I only recently moved to a place that had one. Consequently, I feel inadequate to go into much detail about its ins and outs, so we will resume the discussion of the drugstore game at a later date. Instead we will move on to my favorite grocery store:

Kroger
Initiation
In order to take advantage of any sale going on at Kroger, you must obtain a Kroger card:


You may do this when you first walk in the store at the customer service desk, which is typically located at the front of the building.

Preparation
As before any shopping trip, I look to Jenny to tell me what sales are going on and what coupons I can match with them. Occasionally, sale prices that Jenny lists differ slightly from those at my store due to different pricing in different regions; however, I use Jenny's prices as a guide for any items not listed in the weekly sales flyer on the Kroger website.

In addition to the typical paper coupons that I cut from the newspaper or print from the internet, there are digital coupons that can put on a Kroger card. There are various websites where these coupons can be loaded (cellfire.com, shortcuts.com, kroger.com, upromise.com, to name a few). When you use your Kroger card and purchase the appropriate item(s), these coupons are automatically deducted from your purchase. Note that you cannot use a digital manufacturer coupon with a paper manufacturer coupon; furthermore, the digital coupon loaded onto your card will ALWAYS be used (you cannot choose to use a better paper one), and they will NOT be doubled. Paper coupons will be doubled (up to a certain value) at Kroger; check your store's policy to see what this value is for you. And as always, you can use one manufacturer and one store coupon on a single item.

B1G1 free sales at Kroger (or any other grocery store) can be misleading; these items are simply reduced in price by half. You do not need to purchase two items to see the savings...but you can if you want to. Often there are no limit to the number of items you purchase at Kroger; however, you should always pay attention to the fine print to be sure, especially with products like milk and soft drinks.

Kroger will sometimes have Catalina deals (Jenny also keeps track of these). These are sales where, if you purchase the appropriate item(s), Kroger money will print out at the register. My favorite Kroger deal, however, is what they call a "Mega Event." Typically these events run for two weeks and are centered around a sporting event (March Madness, Indy 500) or a new movie (Cars 2). To take advantage of these deals, you will usually have to buy 5-10 items on a list; then you will automatically receive $3-$5 off your total purchase when you check out. Again there are usually no limits, so for example, if you would receive $5 off the purchase of 10 items, as long as you had y*10 items, you would get y*$5 off at checkout (i.e. $15 for 30 items).

Implementation
When I get to the store, I do my shopping, gathering items from my list, just like normal. One "different" thing that many folks find helpful if a mega event is going on is to bring in reusable bags. Then fill each with the required number of items for the mega event; this helps you to make sure you have the correct number of items. When I've finished my shopping, I'll double check the number and types of items I've picked up, as well as the coupons I had planned to use. Finally, I proceed to the checkout line.

I will place my items on the belt and have the cashier scan my Kroger card. As he/she scans my items, I try to watch the prices on the screen to make sure everything rings up correctly. After he/she is finished, I give any paper coupons I have and any catalinas from previous deals; then I pay the balance.

Kroger receipts give you a nice breakdown of your savings from both sales and coupons. They also track the number of gas points you earn per purchase:


You can use these points to get a discount on gas at the Kroger gas station or participating Shell stations in your area. Any catalinas you have earned through your purchase will print out seperately from your receipt, like at Wags. These typically have a two-week from the date of purchase expiration date.

How many of you enjoy shopping at your local Kroger?

MrsDrPoe: Campus Snapshots

Happy Foto Friday, all! At the beginning of this week, I journeyed to Starkville, MS, home of the MSU Bulldogs (and former home of the Poes). I truly miss seeing *MSU* bulldogs all over the place, like the one outside the union:


And I miss the beauty of the campus at sunset. The tower in the background is part of the Chapel of Memories, where Mr. Poe proposed to me oh so many years ago:


I also miss my cubical office, which I never thought I would; although, it's probably more the processing speed I miss than the actual cube. Of course you can't mention Starkville without mentioning the wonderful people who reside there...people Mr. Poe and I love and miss very much.

Going back to Starkville is like going home.

MrsDrPoe: "Vengeance is Mine"

Happy Theology Thursday to all! The inspiration for today's post is a bit different than usual, but I hope you'll find these thoughts interesting/useful...

Last Saturday night we watched the 2010 remake of True Grit. While there was some language and violence in the film, we found it to be pretty interesting. We thought it was especially neat that scripture was quoted throughout the movie and instrumental versions hymns were used for the background music - not things you typically see in movies these days. (I also liked how very few contractions were employed by the characters, but that's off subject.)

The general plot of the movie is that a 14 year old girl hires a US Marshal to help her find and prosecute the man who shot and killed her father; she is prepared to kill this man herself if he does not receive a death sentence in a court of law. So as the search for the criminal continues throughout the movie, the scripture that is quoted is related to the wicked receiving their punishment. Mr. Poe found it very ironic that this very learned girl neglected Deut 32:35, Rom 12:19, and Heb 10:30, which all tell us that God has said "Vengeance is Mine, I will repay." That made me think of how often people look forward to others "getting what's coming to them."

In the old testament, we frequently see God employing surrounding nations to punish the children of Israel for their unfaithfulness. Later, these nations are judged and punished by God for their own actions and attitudes. In Chapters 25-32 of Ezekiel, the prophet pronounces God's judgement on seven nations neighboring Israel:

In 25:1-7, we are told that Ammon will be judged because "[they] said, 'Aha!' against [God's] sanctuary when it was profaned, and against the land of Israel when it was desolate, and against the house of Judah when they went into captivity." Furthermore, Ezekiel tells us, "Thus says the Lord God: 'Because you clapped your hands , stamped your feet, and rejoiced in heart with all your disdain for the land of Israel, indeed, therefore, I will stretch out My hand against you, and give you as plunder to the nations..."

And in 25:15-17, Ezekiel pronounces God's judgement on Philistia, saying, "Thus says the Lord God: 'Because the Philistines dealt vengefully and took vengeance with a spiteful heart, to destroy because of the old hatred,' therefore thus says the Lord God: 'I will stretch out My hand against the Philistines, and I will cut off the Cherethites and destroy the remnant of the seacoast. I will execute great vengeance on them with furious rebukes; and they shall know that I am the LORD, when I lay My vengeance upon them.'"

From these two passages, we see that the nations of Ammon and Philistia will be punished by God for their desire for revenge against and their enjoyment of the punishment of Israel. It's one thing to execute justice; it's another thing to enjoy it or to seek revenge.

If we again examine God's declaration of His name in Exodus 34:6-7, we see that He is "merciful, gracious, longsuffering, and abounding in goodness and truth," but He is also just in that He is "by no means clearing the guilty..." It's sometimes hard for us to understand how love and justice can coexist, but just because we don't understand doesn't mean they can't. Ezekiel 33:11 says, "'As I live,' says the Lord God, 'I have no pleasure in the death of the wicked, but that the wicked turn from his way and live. Turn, turn from your evil ways!'" We can see the truth in this statement from the way that judgements throughout scripture are declared with woe and lament.

Applying this to our own lives, we should hate sin (in ourselves and in others) and try our best to rid ourselves of it. We should teach against it and, when necessary, discipline those among our number who turn away from God's law (Matt 18:15-17, I Cor 5:9-13). But through this discipline and teaching, we should never find enjoyment in punishment of the wicked. We must keep in mind that all men have souls and are precious to God. We should aid and pray for our enemies (Luke 6:27-36).

Our friend, Mr. Holley, makes the point that often when we watch movies, we get so sucked in to the story that we rejoice when the "bad guy" is killed. But this is a worldly view. We can take comfort in the fact that, ultimately, good has and will triumph over evil (our faith in God is not in vain); however, we should never rejoice when a soul is eternally lost to sin...even in fictional stories.

MrsDrPoe: Pulled Pork BBQ

Happy What's for dinner Wednesday on the blog! Today we'll be discussing a quick and easy recipe that's great for crowds (Mr. Hinds especially likes it) or finals week- pulled pork BarBQ.

Ingredients: 1 pork shoulder (aka pork "butt") or other piece of pork, boneless or otherwise (estimate 4-5 sandwiches per pound of pork), 1/2 cup water, 1 Tbs salt, 1Tbs pepper

Place all these ingredients in a slow cooker (you may need to cut the pork to make it all fit), and cook on low for 10-12 hours:


After the pork has finished cooking, it should be fall off the bone tender. Carefully use tongs to pull the pork out of the pot. Place the meat in a large bowl and shred it using either the tongs or a pair of forks. Add BBQ sauce and toss:


Serve with buns, dill pickle slices, additional sauce, and anything else you like on your BBQ!

MrsDrPoe: Mr. Hinds

Good morning all! Today we'll be continue our Poes' Pals series with a very special friend of ours...Mr. Hinds:

We have known Mr. Hinds for many, many years. Our terms at MSU overlapped for a time, so we were school mates, as well as friends, and family-in-Christ. He was also my neighbor the year before I became Mrs. Poe- Sascha loved to visit him and clean up his crumbs.

Mr. Hinds has been a great encouragement and example to us. He is always concerned with helping others and would never dream of inconveniencing anyone. For instance, in the summer of 2007, I went out to San Diego for the annual ASME fluids conference. I had no car, so Mr. Hinds (who was in north Cali at the time) drove down to take me to Bible study the Sunday that I was there. He then proceeded to chauffeur two of my colleagues and me around the city for the day. Please keep in mind that this is just one example- he has put countless miles on his car over the years to preach, teach and edify others.

We fondly remember his goofiness as well. He loves to sleep in odd places, like on the washing machine and in the beds (oil-filled or otherwise) of pick-ups. And he occasionally has the taste for exotic vegetation. Of course, Mr. Hinds also knew when to be serious. It is largely because of his efforts that this weekly college study first started in a home several years ago. He has laughed with us, cried with us, and rejoiced with us, and we are very thankful to know him!

MrsDrPoe: Taking a Different View on Physics

Welcome to Thesis Tuesday on the blog! Today, as we continue our discussion of basic fluid mechanics, we will examine specifically how fluid mechanics differs from classical physics.

In a typical physics class, we examine moving objects from a Lagrangian viewpoint, meaning that we tag and track information for an object. For a solid mechanics application, like an accelerating car, this viewpoint makes sense- we tag the car and we can track its velocity, acceleration, etc. For fluid mechanics, however, this method entails the tagging and tracking of individual fluid particles, which allows us to know how properties of each particle change with time, but not how properties change with time in relation to position in the fluid. Thus, we employ the Eulerian viewpoint, which provides us with a functional relationship for a fluid property as a function of space and time (i.e. a field).

From these differences stem the terms control system and control volume. A control system is also known as a closed system, meaning that the object we are examining is completely enclosed in the system- nothing flows in or out. This pairs with a Lagrangian "particle-tracking" viewpoint. The control system can move with the particle (ex: a car), but the particle is always contained. A control volume is also known as an open system, where the object we are examining is free to exit, enter, or remain inside the system. This pairs with an Eulerian "field" or "flow" viewpoint. A control surface is the boundary of a control volume.

From basic calculus, we know that, given the functional form of a velocity, we can determine the acceleration by taking the derivative of velocity function. When dealing with a velocity field (V), however, we must take the material derivative in order to find the acceleration field. The material derivative has both a local part and a convective part. The local term (dV/dt) tells us how the velocity at a certain point in the field changes with time, while the convective term (u[dV/dx] + v[dV/dy] + w[dV/dz]) tells us how the velocity changes with respect to position in the flow. For example, if we sit at a restaurant and watch traffic directly in front of us, we can see how the velocity or the "flow" of cars changes with time at that specific location. If we drive down the road examining the speed of our car (or another) as we go from point A to point B, we can see how the velocity of the "flow" of cars changes with position.

Introduction of the material derivative allows for a brief discussion of the Reynolds Transport Theorem. This is a mathematical formulation that allows us to convert the physical laws from a Lagrangian viewpoint to an Eulerian viewpoint. The material derivative of an extensive property (B, property dependent on the amount of mass present) is representative of a Lagrangian viewpoint. This is set equal to two integral terms involving the corresponding intensive property (b, property independent on the amount of mass present; B = mb). The first integral term represents how the amount of b in the control volume changes with time; the second represents the net amount of b that crosses the control surface.

I hope you'll forgive me for looking more at the math behind the scenes today, but this will (hopefully) help those of you with a basic physics background see how fluid mechanics takes a different view of the subject.
