MrsDrPoe: The Rudes

It's time for another edition of Poes' Pals here on the blog!  This morning, I'd like to introduce you to another wonderful family from Starkville...the Rudes:

We've known the Rudes for approximately seven years, and we can attest to the fact that, contrary to what their last name might suggest, they are some of the most caring and friendly folks we know!

Dr. Rude is a professor in the Animal and Dairy Science at Mississippi State University (Mrs. Luke actually had him for a class; she and others have told us that Dr. Rude is a great teacher and his classes were enjoyable and informative).  He is also a great Bible teacher, presenting material in a way that encourages participation.   

Mrs. Rude often teaches French at East Mississippi Community College (we've heard great things about her and her teaching from friends too).  She is one of the most selfless people I've ever met, constantly being aware of the needs and desires of others and striving to help out in whatever way she can.

Ms. Rude may come across as shy when you first meet her, but she is a very spirited, fun-loving, and spiritually minded young woman.  One of my very fondest memories of her is when she went with Ms. K. Davis, Ms. M. Davis, and me to a ladies Bible study in Birmingham- oh what a great time we had!

As you're probably tired of hearing me say, we miss our Starkville family very much, and we hope that if you're ever in the area you'll have an opportunity to meet some of the fine people there!

MrsDrPoe: The First Law of Thermodynamics, Part 6

Hello and welcome to Thesis Tuesday on the blog!  As promised, today we will be finishing our look at the first law of thermodynamics by applying the differential form of the first law to an example problem.

Problem: A liquid is flowing downward along an inclined plane surface, as shown in the figure:

The free liquid surface (y = h) is maintained at temperature Th, and the solid surface (y = 0) is maintained at To.  Determine an expression for the temperature distribution in the film, recognizing that the viscous heating effects can be ignored.

Given: non-isothermal film flow, T(0) = T0 and T(h) = Th
Find: An expression for the temperature distribution in the fluid film
Assumptions: steady, laminar, incompressible, Newtonian fluid, ignore viscous heating effects, constant thermal conductivity, assume T = f(y), constant properties
Solution: 


Starting with the general form of the differential energy equation for an incompressible Newtonian fluid:

rho*cp*(d/dt(T) + u*d/dx(T) + v*d/dy(T) + w*d/dz(T)) = -(d/dx(qx) + d/dy(qy) + d/dz(qz)) + mu*Phiv

Steady flow eliminates the first term on the left side; the last term on the right side is eliminated because we are ignoring viscous heating effects.

rho*cp*(u*d/dx(T) + v*d/dy(T) + w*d/dz(T)) = -(d/dx(qx) + d/dy(qy) + d/dz(qz))

Our assumption of laminar flow means that v = w = 0; the first term on the left side is also zero since T is in not a function of x:

0 = (d/dx(qx) + d/dy(qy) + d/dz(qz))

The flux terms can be related to the temperature gradient using Fourier's law:

qx = k*d/dx(T), qy = k*d/dy(T), and qz = k*d/dz(T)

Furthermore, since the thermal conductivity (k) is constant, our energy equation becomes:

0 = k*(d/dx(d/dx(T)) + d/dy(d/dy(T)) + d/dz(d/dz(T)))

We can divide both sides by k; the first and third terms cancel since T is not a function of x or z:

0 = d/dy(d/dy(T))

If we separate and integrate this equation twice, we end up with the expression:

T(y) = c1*y + c2

We can solve for c1 and c2 by applying the given boundary conditions at 0 and h:

c2 = T0 and c1 = (Th - T0)/h

So we now know the expression that shows us the temperature distribution in the fluid film:

T(y) = (Th - T0)/h*y + T0

Not so bad, huh?  Next week we'll begin anew with a fresh subject, but until then, happy studying!

MrsDrPoe: Highlights from the Week's Beginning

Happy Foto Friday to you all!  The past seven days have been filled to the brim...here are the highlights from the beginning of the week:

I went to Ikea for the first time with Mrs. Holland and Mrs. Clark.  It was a grand trip with fantastic company!  I got all sorts of decoration and storage ideas and had the tastiest (and cheapest) Swedish Meatball meal I may have ever eaten:

And as you know, Monday was October 31 AKA...

1) Halloween.  We celebrated by giving out some candy (to the three trick-or-treaters we had before Bible study) and with hot cocoa from our cauldron mugs Mama Wolgemuth gave us:

2) the Anniversary of Mr. and Mrs. Brodrecht.  The day marked three years of marital bliss for Mr. Poe's sister and hubs.  Yay!

What adventures did you have this week? 

MrsDrPoe: Our Lord and Savior

Today marks another Theology Thursday here on the blog.  As usual, please open you Bibles with me as we look at a portion of God's word.

There are several passages in the New Testament that refer to Jesus as both our Lord and our Savior (Lk 2:11, Ph 3:20, Tts 1:4, 2 Pet 1:11, 2:20, 3:2, 3:18, etc.), but what does that mean to us?

Savior 

This word in the Greek is soter (root word: sozo, meaning "to save"), and it's defined by Thayer as "savior, deliverer; preserver."

It's very easy to see how Jesus is our Savior- He sacrificed Himself on the cross, bearing our sins, so that we may have forgiveness from them...something the blood of bulls and goats could not take away (Heb 10:4).

The thought of having a savior of some kind is pleasing to most if not all people.  We don't want to be hurt; we want to be comfortable, and if someone can give that to us, we gladly welcome him.  As Christians, however, we must not forget that the salvation Jesus provides us is not necessarily from the physical pains of this world- we will see trials and persecutions.  He has saved us from the tyranny of sin and spiritual death.

Lord 

This word in the Greek is kyrios (root word: kuros, meaning "supremacy"), and it's defined by Thayer as "he to whom a person or thing belongs, about which he has the power of deciding; master, lord.

Throughout the gospels, we find examples of Jesus' supremacy over all things in both the physical and spiritual realms: storms (Mark 4:35-41), leprosy (Mark 1:40-45), paralysis (Mark 2:1-12), demons (Mark 5:1-20), death (Mark 5:21-43), etc.  

All too often, however, we simply think of "Lord" as a synonym for "Jesus."  While the two can be used interchangeably, we must realize that the nuances of this terminology.  Jesus is to be our Master, which makes us His servants.  As servants, we must strive to do the will of our Master always- servitude isn't an 8-5 job.


As Mr. Holley always says- everyone wants a "Savior," but most don't want a "Lord."  It is imperative that we, as Christians, keep in mind that Jesus is both our Lord and Savior...we have been saved from sin to serve the Master of all things (Rom 6:1-7)- the True and Living God!

MrsDrPoe: Lemon Pepper Tilapia

It's What's for Dinner Wednesday again, and I'm hungry! Tonight I'll be sharing another one of Mr. Poe's favorite dishes, Lemon Pepper Tilapia.

Ingredients (per person): 1 Tilapia fillet, 2 tablespoons lemon juice, 2 teaspoons lemon pepper seasoning.

Place fillet on a piece of aluminum foil, and sprinkle the lemon pepper seasoning over it. Bring the left and right sides of the foil together over the fish and fold or roll up. Then seal the far end of the foil pocket by rolling or folding up that end:

Carefully pour the lemon juice in through the open end of the foil, and fully seal the pouch by rolling or folding up this end. Place on a cookie sheet (in case the juice leaks), and bake the fish at 400 degrees for approximately 15 minutes or until the fillet transforms from transparent to white and flaky:



Mr. Poe and I love to also put sliced bell pepper and cherry tomatoes in our Tilapia pouches, and we serve it over rice (the juice makes a great "gravy"). Enjoy!

MrsDrPoe: The Love and Respect Experience

It's time for another Reading Review here on the blog.  Today I present to you another book that I received free from BookSneeze: "The Love and Respect Experience: A Husband-friendly Devotional that Wives Truly Love" by Dr. Emerson Eggerichs.

As the subtitle suggests, this book is comprised of 52 devotionals geared toward helping couples improve their marriages through growing together in Christ.  Each devotional is about three pages long and focuses on applying a verse or two from a particular Bible passage to marriage.  There are discussion questions for each devotional in the appendices, as well as contact information for counselors and a summary of Dr. Eggerichs' "Three Cycles of Love and Respect."

I enjoyed reading through this work and would recommend it to anyone even considering marriage.  The idea of husbands growing in love for their wives and wives in respect for their husbands is an often difficult-to-implement command of God, but it's one that the prayer and activity suggestions presented in the book will help with tremendously.  I did not, however, care for the thirtieth devotional, which essentially said, "tell everyone to buy my book."  Also, most of the ideas presented are directly from scripture, but as with any spiritual book, I recommend reading with an open Bible, since there is no substitute for the Word itself.

Since this is a couple's devotional, I asked Mr. Poe to examine the book too.  He thought that this work was well-written and that it contained useful activities and information throughout the book and its appendices.  He found it to connect real-life application to Biblical principals very well, but he did not appreciate Dr. Eggerichs' constant use of his own marriage as an example.

MrsDrPoe: The First Law of Thermodynamics, Part 5

Happy Thesis Tuesday to you all!  Today we'll be continuing our discussion of the First Law of Thermodynamics by examining its final form- the differential form.  For an incompressible, Newtonian fluid in Cartesian coordinates, this is:

rho*cp*(d/dt(T) + u*d/dx(T) + v*d/dy(T) + w*d/dz(T)) = -(d/dx(qx) + d/dy(qy) + d/dz(qz)) + mu*Phiv

where

qx = d/dx(k*T), etc.

Phiv = 2*((d/dx(u))*(d/dx(u)) + (d/dy(v))*(d/dy(v)) + (d/dz(w))*(d/dz(w))) + (d/dx(v) + d/dy(u))*(d/dx(v) + d/dy(u)) + (d/dy(w) + d/dz(v))*(d/dy(w) + d/dz(v)) + (d/dx(w) + d/dz(u))*(d/dx(w) + d/dz(u)) - (2/3)*(d/dx(u) + d/dy(v) + d/dz(w))*(d/dx(u) + d/dy(v) + d/dz(w))

Typically, Phiv is neglected.  It is only important for flows with large velocity gradients or very large viscosities.  Furthermore, it should be noted that if the fluid has a constant thermal conductivity, the first term on the right-hand side of the equation becomes:

(d/dx(qx) + d/dy(qy) + d/dz(qz)) = k*(d/dx(d/dx(T)) + d/dy(d/dy(T)) + d/dz(d/dz(T)))

So the final equation that we will be dealing with is:

 

rho*cp*(d/dt(T) + u*d/dx(T) + v*d/dy(T) + w*d/dz(T)) = -k*(d/dx(d/dx(T)) + d/dy(d/dy(T)) + d/dz(d/dz(T)))

In these equations, T is the temperature of the fluid and q is the heat flux.  Next week we'll conclude our look at the first law with an example employing this differential equation.

MrsDrPoe: New Friends

This Foto Friday on the blog, I'd like to show you a cute picture of the new friendships that were made this weekend:

Lou Grantham met Layla and Sascha.  They got along pretty well- as long as Penny wasn't in the room.  How exciting for the girls to have a new doggie friend!

MrsDrPoe: Teaching Children

Once again it's Theology Thursday on the blog, and as always, I invite you to open your Bibles as we look at another portion of God's word.

A few years ago in Starkville, the theme of the ladies' summer Bible class was 'teaching more difficult Bible passages to children.'  Many of us younger ladies learned a lot from those who have had much experience in this area through teaching both their own children and others'.  After much waiting, learning, and praying, last Sunday I had my first experience in a children's Bible class.  It went well, and I'm very excited to learn more about teaching young minds what God has revealed to us through His word from the lead teacher.

While some people may view teaching Biblical truths to children in a negative light, preferring instead to 'let them make their own spiritual decisions,' this idea is contrary to the Biblical model.  In Deuteronomy 6:6-9, the Israelites are commanded, "And these words which I command you today shall be in your heart.  You shall teach them diligently to your children, and shall talk of them when you sit in your house, when you walk by the way, when you lie down, and when you rise up.  You shall bind them as a sign on your hand, and they shall be as frontlets between your eyes.  You shall write them on the doorposts of your house and on your gates."  This passage points out the great effort with which they were to strive to continually teach their children through both word and example.

Although this command was given as part of the Old Law, passages in the New Testament clearly demonstrate that it applies to Christians under the New Law too.  For instance, Ephesians 6:4 says, "And you, fathers, do not provoke your children to wrath, but bring them up in the training and admonition of the Lord."  Clearly, teaching our children things of a spiritual nature is important to God, and as such, it should be important to us as well.

Suppose someone wanted his/her (young) children to make their own academic decisions.  How many kids would choose recess or staying home over learning how to count or multiply or work with fractions?  Obviously not everyone will enter a math-intensive field, but we teach our kids basic math because we see that these skills are important.  And math is important...but the word of God is so much more so!

Ultimately, our children will make their own decisions about whether or not they will follow the Lord, just as they will make their own decisions about pursuing a career in engineering or public relations.  However, this fact does not negate our responsibility to teach our children the Bible.  Our refusal to do so is not just 'allowing our children to make their own spiritual decisions' or even 'taking the easy way out'- it's blatantly choosing to disobey a command from God.  I encourage you all whether you're a parent or not to join me and help teach our children about Jesus and what He did for us all!

MrsDrPoe: Garden's Bounty Pasta

It's Wednesday once again, and tonight I'd like to share with you my Garden's Bounty Pasta.  This dish is a quick vegetarian meal that works well with whatever veggies you have on-hand.

Ingredients: pasta (go healthy with wheat!), 1 zucchini, a handful of green beans, 1/4 of a medium onion, 1/2 - 1 cup of pasta sauce, 2 tablespoons olive oil (not pictured), 2 teaspoons Italian seasoning (not pictured), mozzarella cheese (not pictured), and salt and pepper (not pictured).

While the pasta is cooking, chop up the veggies and toss them in a large skillet with the oil and seasonings:

Cook the veggies until just tender, then add the pasta sauce.  Serve the veggie sauce over the noodles with some mozzarella cheese:

Enjoy! 

MrsDrPoe: The Davis Family

For the next edition of Poes' Pals, I'd like you to meet the Davis Family:

We visit the Davis family every time we go to Starkville.  They are fantastic people, and we love them very much!  Mr. G. Davis and Mrs. Davis just built a beautiful house that they allowed me to invade during my last business trip to MSU.  Mr. Poe and I have greatly appreciated their example and advice; they are wonderful Christians who have raised some great kids.

Ms. K. Davis is one of our dearest friends (and our "adopted" sister and daughter).  She helped us move to Atlanta and has been on many a road trip with us; we talk almost daily.  We hope to persuade her to join us in Georgia when she graduates in Graphic Design from State in December.  Ms. M. Davis is such a sweetie as well- during my two week stay, we shared many a breakfast, car ride and evening together.  She just started her first year in pre-nursing at State this fall, and we know she will make an excellent nurse!  Mr. J. Davis is like a brother to us.  He and Mr. Poe love to talk sports, and we all love to trade jabs and jokes when we get together.

As with the Holleys, we suggest you take some time to visit the Davis family next time you're in the Starkville area- we certainly look forward to it!

MrsDrPoe: The First Law of Thermodynamics, Part IV

Happy Thesis Tuesday!  Today we'll continue our discussion of the head form of the First Law of Thermodynamics with an example problem:

Water is moved from one large reservoir to another at a higher elevation.  The loss of available energy associated with 2.5 ft*ft*ft/s being pumped from sections (1) to (2) is 30.5 |V|*|V|/g, where |V| is the average velocity of water in the 8 in inside diameter piping involved.  Determine the amount of shaft power required to pump the water.

Given: Q = 2.5 ft*ft*ft/s, losses = 30.5 *|V|*|V|/g, zdelta = 50 ft, D = 8 in

Find: shaft power required

Assumptions: steady, laminar, 1D, incompressible, constant average velocity, and constant properties

Solution:

For this case, we do not need to consider the continuity equation if we set our problem up correctly.  So we will start with the head form of the energy equation:

(pout/gamma) + 0.5*|V|*|V|/g + zout = (pin/gamma) + 0.5*|V|*|V|/g + zin + hP - hL

We will chose "in" as a point at the surface of the lower tank and "out" as a point at the surface of the upper tank, which tells us:

pin = 0, pout = 0 since both surfaces are exposed to the atm

vin = 0, vout = 0 since we can assume that the water on the surfaces is still

zin = 0, zout = zdelta setting z = 0 at the surface of the bottom tank

In putting these values into the equation, we have:

zout = hP - hL where hL = losses

Since our equation for the losses is given as a function of the average velocity, we know that these losses are primarily due to the friction in the pipe.  We can determine this velocity since we know both the flow rate and the pipe diameter.  NOTE: Q = |V|*A is only valid for use with uniform velocity or average velocity.  We know that since there are friction losses, mu is not zero, our velocity is not uniform, so in order to use this equation, we must use average velocity, which we are given.

|V| = 4*Q/(pi*D*D) = 7.162 ft/s

hL = 30.5*|V|*|V|/g = 48.625 ft

Solving for hP:

hP = zout + hL = 98.625 ft 

(since this answer is positive, work is introduced INTO the flow)

Now we can determine the necessary power from the pump head:

Wreq = hP*gamma*Q = 20,850 W = 27.958 hp

And that's the head form of the equation.  Next week, we'll look at the differential form of the First Law!

MrsDrPoe: A Beginners Guide to Couponing, Part 9

Happy Money Monday to all!  Today we'll be revisiting out "Beginners Guide to Couponing" series with some tips on how to save money at a store I've gotten a lot of great deals at recently, JCPenny.


Initiation


Like most department stores, anyone can shop at JCPenny and get sale prices on items without a store credit or membership card.  However, in order to better take advantage of the deals at JCP, you should sign up for the JCP Rewards Program and link up to three of your credit or debit cards to your account so your purchases made at JCP with the card(s) can earn rewards for you.  If you wish, you can also apply for a JCP Rewards Credit Card (platinum, gold, or red) for 25% more rewards points and other perks (this may be a good option for you if you're credit card shopping to avoid monthly debit card fees).


The rewards program gives you 1 point per every $1 spent in store and online with your registered card(s) (including the purchase of clearance items).  For every 250 points you earn, you will receive $10 in JCP Rewards, usable toward anything in the store.  Also, each month you spend at least $1.00 at JCP, you will earn double points (2 per $1 spent) the following month.


Preparation

Just as with any other couponing adventure, before going to the store, you should make a list of items you're interested in and see what coupons are available.  Every week, I receive a text and/or an email with a x% off or $y off a purchase of $z.  (In September I got two texts for $10 off a purchase of $10 or more in Liz Claiborne and in Call It Spring items.)  You can often obtain additional 15-20% off coupons by reviewing a previous purchase (must be done within one week of the purchase date).  Although most coupons do not stack, you can use the $10 JCP Rewards that you earn with percentage off coupons, making your rewards even sweeter.


Another aspect of couponing at JCP that one should be aware of is the awarding of bonus points for shopping on a certain day or for purchasing a certain brand (these are indicated on the "bonus" and "my accounts" tabs on the JCP Rewards site).  For instance, I earned 25 points just shopping on Columbus Day, 50 points for purchasing a clearance Liz Claiborne shirt, and 50 points for purchasing a Total Girl shirt- 125 points in addition to those earned for each dollar I spent.  So in a single purchase ($4.26 OOP), I ended up over 1/2 way to earning a $10 reward for this month.


Implementation


When I go to my local store, I look around for the types of items I had on my list, snatch them up, and try them on when necessary.  Then I make my purchases, present my coupon(s), and check-out with my registered card.  When record of my purchase shows up on my JCP Rewards online account about two days later, I double check to make sure everything is correct, and look forward to my next reward.  Also, at the end of each month, I've also received an email with links to brief video adds that I could watch for 50 rewards points each.  




I hope this information helps you...especially with the holidays coming up!
