For pastors and evangelism teams on American college campuses who want to tell international students about Jesus Christ, the challenges are many – not the least of which can be the language barrier.
But now, thanks to a mission grant provided by the LWML Iowa East District, the Lutheran Heritage Foundation (LHF) is providing campus ministries with a valuable resource for sharing the Gospel: good Lutheran books translated into the languages of the people they serve.
"60 to 70 percent of our international students come from countries where there's very little opportunity to meet a Christian, get a Bible or visit a church," said Hannah Moore, coordinator of international ministry at Memorial Lutheran Church and Student Center near the Iowa State University campus in Ames.
"We have to begin at a very basic level. For example, a Chinese man told us his brother and sister were both baptized, but this man didn't know the word for baptized," she said. "He wanted to know what baptism is, and a book like Luther's Small Catechism in his language is helpful for answering some of those very basic questions about what the Bible teaches."
LHF is a recognized service organization of the LCMS, dedicated to translating and publishing good Lutheran books into the languages of the world. Over the past 23 years, LHF has translated over 725 books like Luther's Small Catechism and A Child's Garden of Bible Stories into 83 languages, and the books are given free of charge to the ministries that need them.
"LHF is so awesome with the translation," said Rev. John Wegener, pastor of College Hill Lutheran Church, which serves the University of Northern Iowa campus community in Cedar Falls. "We have the greatest gift in books like catechism, and with those materials translated into languages our international student can understand, we can use them to communicate the Gospel clearly. Otherwise, we'd really be lost."
Many campus ministries offer free English as a Second Language (ESL) classes as a way to begin a relationship with international students who are far from their homes and culture.
"International students are in a foreign place, not in their comfort zone," explained Hannah. "In campus ministry, we see that God really prepares a lot of hearts to lean on Him and turn to Him in those teachable moments."
During those teachable moments, a book in the student's own language is a precious gift.
After sharing the very basics of the Christian faith – Who is God, and what is the Bible? – campus ministry teams rely on LHF books to take the next step in catechism instruction.
"It's an amazing thing when you hand someone a catechism in their own language," said Rev. Max Mons, pastor at St. Paul's Lutheran Chapel and University Center in Iowa City. "Their response is, 'Wait, this is for me?' And we say yeah! I've done this many times now. First, we'll read the catechism together in English, then I'll give them a moment to read it in their own language. Then their eyes light up, 'Okay, I get it now!' And then we can go on from there."
The LWML Iowa East District's mission grant is also helping LHF to provide Lutheran texts for International Student Ministry's upcoming "In-Depth Bible Seminar" in St. Louis, Mo. Kate Cole, leader of the International Friends Association at the University of Michigan campus in Flint, is helping organize the seminar.
"This is a nationwide effort, and only about 15 students come to this seminar," Kate explained. "Only serious seekers – those who have been involved in Bible study for at least six months – are eligible."
The participating international students will engage in more Bible study and worship. In addition, Kate will help organize small groups of students and give them information on how to start their own small groups.
"The experience that we've had at past seminars is that about half of the participants ask to be baptized when they're finished with the seminar," Kate said.
While baptism and confirmation are goals for most Lutheran campus ministries, the short time international students spend on American campuses (usually only 2-3 years) sometimes only allows for friendships to be formed and questions to be asked. But the relationships that take root often continue even after the students have returned to their home countries.
"There was a Chinese woman who had contact with us at College Hill for a couple of years," said Rev. Wegener. "She's moved now to California, but she still has contact with [a parishioner] through email. Our parishioner said that the last time they emailed, they had a good discussion about the faith, so she's still connected to the church in this way."
When international students do leave the campus, they take with them the Lutheran books LHF has provided, and the books continue to teach for a lifetime. "We're doing a lot of seed planting," concluded Rev. Mons.

With so many Houston homes facing a higher risk of flooding than expected, flood control strategies have become more important than ever before. While most properties require different measures to keep floodwaters at bay, home elevation is the surest way to minimize damage to your home and keep your family safe when a flood affects your area. If your home was damaged during a flood, choosing the right elevation solution for your property is extremely important in order to make the most of your investment.
Home Elevation Solutions for Houston Homes
In some rare cases, Houston homes require a few minor drainage changes in order to prevent or minimize flood damage. While grading the landscape to achieve positive drainage and installing underground drainage pipes, French drains, and/or weeping tile systems could help homeowners drive water runoff away from their homes and prevent damage, these measures often prove insufficient during major flood events. Because elevation provides the best protection from flood damage, we'll use this blog post to present the most appropriate home lifting solutions for Houston homes.
Lifting the Entire Home and Extending the Foundation
Unlike other home elevation methods, this technique can be used for any masonry or frame home. In most cases, this technique implies:
- using a hydraulic lifting system to raise the home* above the BFE recommendation and holding it up with the help of temporary supports until pile guard piers or driven concrete piers are installed underneath;
- extending the walls of the existing foundation or building a new foundation from brick masonry, concrete blocks, or poured concrete, which meets the current flood protection standards for the area**;
- lowering the home back down onto the new foundation or extended foundation walls;
- installing openings in the foundation walls to allow for automatic entry and exit of floodwaters.
*In a frame home, the frame and the walls are separated from the foundation before the home is lifted. The homes that sit on slab-on-grade foundations are lifted together with the slab.
**In areas where the soil conditions aren't ideal for masonry or concrete slab foundations, pier and beam foundations are often recommended. Because this type of foundation is elevated on concrete pilings, concrete piers, or wood posts—so it doesn't rest directly on a concrete slab—it allows floodwaters to flow freely beneath it.
Extending Your Home's Walls Upward and Raise the Floor
Particularly recommended for concrete-block and brick masonry homes, which don't include structural elements that are vulnerable to flood damage (e.g. wood studs), this method involves:
- removing the roof, windows, and doors along with their frames;
- extending the existing walls by adding concrete-block or brick masonry;
- constructing a new wood-frame floor or concrete-slab floor that meets the BFE requirements for the area;
- framing the new part of the wall, adding sheathing, and applying stucco or siding in order to bridge the existing part of the wall and the new part;
- reinstalling the roof, windows, and doors;
- removing bricks or concrete blocks from the walls of the lower area of the home so that floodwaters can flow freely in and out; this will help equalize the external and internal hydrostatic pressures on both sides of each wall.*
*When a new concrete-slab floor is built, a layer of dirt, gravel, sand or crushed stone is placed under the slab. Because the entire under-floor space is filled with subgrade/subbase materials, openings in the walls of this space are no longer required.
Building a Second Story and Abandoning the Ground Level
This method is often used when a home must be raised more than 4 feet above the existing grade in order to meet the required BFE for the area. In general, it's more practical to add an entire second story to a home than to extend the existing foundation or the home's walls upward several feet. The area under your new living space can be used for parking, storage, or a different purpose. This home elevation technique involves the following steps:
- removing the entire roof from the home;
- building the second story, according to project specifications*;
- adding sheathing to the walls of the second story, installing the windows, and applying stucco or siding to the sheathing;
- installing flood vents in the walls of the abandoned ground level in order to allow floodwaters to enter and exit freely;
- reinstalling the roof or installing a new roof.
*A second story will add significant weight to the existing structural components of the home. As a result, a second-story addition blueprint is typically required. The second story can be built of masonry, wood-, or metal-framing wall systems.
Typically, home elevation is a complex, relatively expensive undertaking regardless of the home lifting solutions selected. However, rebuilding a home damaged by flooding is often far more expensive, time-consuming, and labor-intensive. But the most important aspect is that lifting your home allows you to keep your family safe during future flood events. All things considered, elevating your Houston home before a flood strikes is one of the best decisions you can make in your life.

Title: Understanding the Role of Solvation Forces on the Preferential Attachment of Nanoparticles in Liquid
We discuss optimization of colloidal nanoparticle synthesis techniques, which requires an understanding of underlying particle growth mechanisms. Nonclassical growth mechanisms are particularly important as they affect nanoparticle size and shape distributions, which in turn influence functional properties. For example, preferential attachment of nanoparticles is known to lead to the formation of mesocrystals, although the formation mechanism is currently not well-understood. Here we employ in situ liquid cell scanning transmission electron microscopy and steered molecular dynamics (SMD) simulations to demonstrate that the experimentally observed preference for end-to-end attachment of silver nanorods is a result of weaker solvation forces occurring at rod ends. In conclusion, SMD reveals that when the side of a nanorod approaches another rod, perturbation in the surface-bound water at the nanorod surface creates significant energy barriers to attachment. Additionally, rod morphology (i.e., facet shape) effects can explain the majority of the side attachment effects that are observed experimentally.

Class Notes
The notes below are by the students and for the students. Hopefully they are useful, but they come with no guarantee of any kind.
First Hour
We begin by reformulating our previous lemma into a more general form:
Lemma 1
Let be a covering map. Then every family of paths such that has a unique lift such that
0)
1)
Claim 1: is well defined, hence
Proof of Claim 1
We construct the homotopy H between two such gamma's which, schematically, is a square with along the bottom, along the top and along the side the parameter Y where the homotopy is just horizontal lines between and
Then, the lemma implies the existence of a homotopy which is schematically a square with along the bottom, along the top, x=0 on the left and side and the right hand side taking values in
Proof of Lemma 1
Recall the proof for the version of the lemma when we were dealing with a single path, not a family. We now just need to extend this proof to the case of having a family of paths. We know that for each we can get a
We need to show that in fact the result is continuous. As continuity is a local property, we simply need to prove this in a neighborhood about .
Now by a "good" open set in B, we mean that the preimage under p CAN be written as a product.
Hence, we choose a neighborhood about the first interval in extending from (see proof of one path case for explanation) and this gets mapped to a "good" open set in B. As it is the image of an interval, it is compact in an open set, so can put a small neighborhood about the interval such that the image of the neighborhood is in the "good" open set in B.
Then, duplicating the proof of the earlier version of the lemma, this establishes continuity in the neighborhood.
Applications of
1) We get again the proof of non existence of a retract
Indeed, assume we DID have such a retract. We would have the following commuting diagram.
Applying the functor would yield the diagram
But clearly this does not exist, as the only map from is the trivial one.
Recall the non existence of such retracts implies Brouwer's Theorem
2) Fundamental Theorem of Algebra
if is a polynomial with degree greater than zero then such that
Proof:
Suppose not, i.e., there exists a polynomial p that has no roots. dividing by the coefficient of the highest order term, lower order terms.
Define a homotopy of paths by first setting
Now the homotopy starts with a base of q on the point 0. During the first half of the homotopy we grow the size of the loop on which q is acting. At the halfway point, the loop is so large such that the first term in the polynomial dominates the lower order terms. Then in the second half of the homotopy, the lower order terms are shut off. More precisely we consider the polynomial (lower order terms) and let tend from 1 to 0 in the second half of the homotopy.
Hence, at the end of the homotopy we are left with on a large loop. This is the generator we had previously, and is not the identity. Hence, we have a constant homotopic to something non trivial and this establishes the contradiction.
3) Boruk-Ulam
If is continuous then such that
Corollary:
1) is not a subset of (cannot be embedded) as f is not 1:1
2) If , with closed then at least one contains a pair of antipodes.
Example:
This is NOT true with 4 sections. For instance consider a triangular based pyramid inscribed inside a sphere with each face a different colour. Imagine a light bulb at the center of the sphere so that on the sphere we get 4 sections with 4 different colours from each side of the pyramid. Clearly none of them contains a pair of antipodes, yet are closed with a union of the whole sphere.
Second Hour
Proof of Corollary:
Consider by (dist to , dist to )
If f(p) = f(-p) then, for both possible cases of f(p) being zero or positive, we get that p and -p are in the same .
Definition:
1) is even if
2) is odd if
Lemma:
1) If is even then ind is even
2) If is odd then ind is odd
Proof of Borsuk-Ulam:
Assume has no p with f(p)=f(-p)
Define by
is odd. Therefore, is non zero.
But is homotopic to zero, a contradiction (the homotopy is a series of circles of decreasing radius where a point on the equator is fixed and its antipodal point is moved in an arc towards it)
Proof of part 1 of lemma:
Suppose is even
We can make a commuting diagram where is the same as going from first via and then from via
We now consider this diagram under the functor
We get
which commutes with along the bottom
which is even.
(Note, by we mean the identity)
Unfortunately, there is no simple adaption of this proof to deal with the odd case and so we introduce some more machinery first.
Definition
A topological group is a topological space G with a group structure such that all group operations are continuous
Examples:
1) (with rotation giving the group structure)
2) SO(3) (See a previous lecture for more info)
If G is a topological group there are two "products" we can define on :
1) with being simply concatenation
2) where
Claim:
These two are the same and, in fact, are commutative. I will not attempt to describe the homotopy schematic here.
We return to the proof of the odd case of the lemma:
Assume is odd. Then is even so . Therefore, is odd.
Note: The addition above is done in which is just
Q.E.D.
Claim:
If are homotopic then
Consider a loop in X. Consider the images of this in Y under f and g. They look like two loops with the same base point and the homotopy H collapses them down to the same loop.
Then, is homotopic to using as the homotopy.
Theorem
1) is an equivalence relation.
2) It is an ideal in the category of topological spaces. That is, and for h's such that these make sense.
Definition
X and Y are "homotopy equivalent" if they are isomorphic in {Topological Spaces} / {homotopy of maps}
I.e., so that and for and
Example
1) is homotopy equivalent to a point via f which takes to a point and g is the zero map
2) An annulus is homotopy equivalent to . Indeed, consider the map f which collapses the annulus to the circle in its middle, and g is just the identity.
3) Likewise for the figure "thick A" which is a subset of the plane in the shape of an A with everything being thick. There is a circle around the hole in the A. The map f just takes A to this circle and g is the identity.
4) The mobius band is also equivalent to a circle where f just collapses to the boundary circle.
This last example gives us some idea of the limitation, or "lack of subtlety" to our invariants given that we would all agree there is something fundamentally different between the mobius band, the annulus and the circle, homotopy equivalence is not sensitive to this difference.
Claim
If X and Y are homotopically equivalent then
Proof:
Consider and forming a commuting diagram and lets consider its image under
Then we get and ) as a commuting diagram.
We know that is homotopic to the identity, and thus we also get homotopic to the identity
Q.E.D.
Theorem
Example:


followed by one or more tags. All we need to do to assure the constrain is obeyed in the instances is declare the chapter class in this straightforward manner. No methods are programmed by the library user, and there is no imperative flow within the classes.
The main "trick" involved in programming parent classes like gnosis.xml.validity.Seq is to look at the.__class__ attribute of an instance during initialization. The class chapter does not have its own initialization, so its parent's __init__() method is called, but the self passed to the parent __init__() is an instance of chapter, and it knows it. To illustrate, this is part of the implementation of gnosis.xml.validity.Seq:
Example 6. Class gnosis.xml.validity.Seq
class Seq(tuple):
 def __init__(self, inittup):
 if not hasattr(self.__class__, '_order'):
 raise NotImplementedError, \
 "Child of Abstract Class Seq must specify order"
 if not isinstance(self._order, tuple):
 raise ValidityError, "Seq must have tuple as order"
 self._tag = self.__class__.__name__
Once an application programmer tries to create a chapter instance, the instantiation code checks that chapter was declared with the required _order class attribute, and that this attribute is the needed tuple object. The method validate() performs some further checks to make sure that the objects the instance was initialized with belong to the corresponding classes specified in _order.
When to Declare
A declarative programming style is almost always a more direct way of stating constraints than is an imperative or procedural one. Of course, not all programming problems are about constraints; or at least, that is not always a natural formulation. Problems of rule-based systems, though, such as grammars and inference systems, are much easier to manage if they can be described declaratively. Imperative verification of grammaticality quickly turns into spaghetti code and is difficult to debug. Statements of patterns and rules can remain much simpler.

The UGB-2M4 is our universal mini directional drilling rig, designed with the utility contractor in mind. It has been engineered to operate as a pit launch machine and as surface launch HDD machine, and provide 2.2 ton of push and 3.1 pull force.
The UGB-2M4 can install Ø250 mm (10″) steel or PVC pipes in a normal soil conditions, fit in an excavated pit just over 1500 mm, and can install the drainage pipe with a slope.
Thereby machine can work from the ground surface like conventional HDD drilling and from the pit like thrust boring machine, making it an even greater tool for pipe and cable laying and utility contractors.
How to work from the surface of the earth:
The machine is placed on the surface of the earth and fixed by anchors, the carriage of the machine is installed at the desired angle (or exactly in the horizontal plane), the drill rods enter to the ground at an needed angle, then the laying path changes to a horizontal plane, the drilling path can be changed, for example, so that the tip goes into the well or into the basement of the room or even to the surface of the earth.
How to work from the pit or basement:
The machine is located in a pit and fixed by anchors, the carriage of the machine is installed in the horizontal plane (or in desired angle), drill rods enter the soil in a horizontal plane, then the drilling path can be changed, for example, so that the tip goes into the well or into the basement of the room or even to the surface of the earth.
Path control is the same as in conventional HDD drilling rig, with the help of underground location systems such as ERA or SNS (Russian made) or Mark, DigiTrack, Subsite and others.
How to drill vertical wells:
The UGB-2M4 machine is placed on the surface of the earth and fixed by anchors, the carriage of the machine is fixed vertically, the well can be drilled to a depth of up to 100 meters.
The UGB-2M4 is perfect choice for laying communications under roads and objects, for connecting houses to gas pipelines, water, sewers, for laying electric and optic cables.
- universality of application in any conditions;
- easy steerable thrust boring at a distance of up to 100 meters with a hydraulic driven rotating;
- powerful traction in compact sizes;

The alter Command
The alter command allows circuit parameters to be changed for the next simulation run.
alter [device_list , param [=] value [param [=] value ... ]]
The parameters will revert to original values on subsequent runs, unless the alter command is reissued.
If given without arguments, a list of previously entered alterations of the current circuit, to be applied in the next analysis run, is printed. List entries may have come from previously given alter commands, or from assignments to the @device[param] special vectors.
The device_list is a list of one or more device or model names found in the circuit. The names are separated by white space, and the list is terminated with a comma. Following the comma is one or more name/value pairs, optionally an equal sign can appear between the two tokens. The name is a device or model keyword, which should be applicable to all of the names listed in the device_list. Note that this probably means that the device_list can contain device names or models, but not both. The device and model keywords can be obtained from the show command.
The alter command can be issued multiple times, to set parameters of devices or models which can't be intermixed according to the rule above.
The device_list can contain ''globbing'' (wild-card) characters with similar behavior to globbing (global substitution) in the WRspice shell. Briefly, '?' matches any character, '*' matches any set of characters or no characters, ''[abc]'' matches the characters 'a', 'b', and 'c', and ''a{bc,de}'' matches ''abc'' and ''ade''.
When the next simulation run of the current circuit is started, the given parameters will be substituted. Thus, the show command, if given before the next run, will not show the altered values. The internal set of altered values will be destroyed after the substitutions.
Examples:
alter R2, resistance=50
alter c{1,2,3}, capacitance 105p

How Do Faucets Work?
Whenever you need to take a bath or wash your hands, water is available immediately via the use of a faucet. A simple twist or lift of the handle releases a gush of water. While it may not be immediately clear why the water comes out of the tap instantaneously, the mechanics behind faucets are very simple.
Inside the Pipes
If you were to puncture the piping that leads to the faucet, you would quickly discover that there is water always circulating throughout the plumbing. You would also realize that the water is kept under intense pressure. In fact, many modern home plumbing systems have water pressure of 125 pounds per square inch. When a liquid is kept under pressure, its first inclination is to move to an area of lower pressure when the opportunity arises.
Faucet Components
Inside of the faucet, three main parts are at work. The first component is the pipe that leads in from the water source to the faucet. The second part is an apparatus that involves a passageway and a stopper. The stopper is equipped with a rubber washer and it can either close or open the flow of water. Thirdly, a short piece of pipe extends between the passageway and the outlet of the faucet.
Pressurized
The first pipe that is connected to the water source is where the water is kept at a high pressure. To release the pressurized water, the stopper that is covering the hole is lifted. The more the stopper is lifted, the faster water comes out of the outlet of the faucet.
Twisting Mechanisms
The mechanics behind how the stopper is lifted depends on the type of faucet. The two most common types of faucets are the ones that twist open and the ones that lift open. Handles that need a twisting motion are connected to the plugging mechanism with a spiral device that allows it to slowly twist into the hole. Moving only a fraction of an inch for every revolution of the handle, twist-based facets make it easy to control the flow of water.
Lifting Mechanisms
Faucets that are lifted use the same concept, only the plugging mechanism goes straight up-and-down instead of easing its way into the gap. Although these work equally as well in terms of releasing the water, lift-based facets aren't nearly as precise.
Motion Detector Faucet
A relatively new type of faucet is the motion detector facet. These faucets release a stream of water for a short period of time once it has detected motion. Despite the difference, the basic principles are the same, with the human aspect replaced with an extra mechanism that raises and lowers the stopper automatically.

Kangaroo's Things To Do
You can use this design to make a model kangaroo that stands up.
First, print off this outline of half a kangaroo on to thin paper.
I suggest you make the kangaroo out of card that is thin enough for you to fold and cut easily. Something like a minilla folder.
Most kinds of card fold easier in one direction than the other. Fold it the easy way, making sure you have enough card for half a kangaroo to fit on each side of the crease.
Fold over the paper print-out so that the middle of the kangaroo's back runs along the crease.
Put the fold of the cardboard inside the fold of the paper pattern. You are going to use the pattern to guide you as you cut through the two thicknesses of card and the two thicknesses of paper at the same time.
You can put paper clips or other kinds of spring clips over the back fold to hold them together while you are cutting.
Here are five helpful tips for cutting that not many people know.
1. Cut very slowly with your scissors, using only the half of the blades nearest the hinge. Don't snip near the points.
2. Keep your sissors hand in the same place most of the time. I rest my arm on the arm of a chair, so my hand is nice and steady.
3. Use your other hand to twist and turn the cardboard, or whatever you're cutting, and feed it into the blades as they slowly close.
4. The best way to cut out complicated designs is to cut the inside of tight shapes first.
5. Where possible, try to cut from large spaces into tiny spaces and pointed places, even if it means making several cuts from different directions.
In making the model kangaroo, I'd first roughly cut away most of the spare paper and cardboard, so the model is easy to handle.
Next I'd look for tight spaces - the main one is between its front paw and its ear.
I'd aim my first cut to hit the widest part of its ear, on the outside, and cut into its arm-pit - right to the end of the line. Then I'd start at his finger tips and move the card around until my second cut also ended up beyond the dashes.
It doesn't matter what order you do the rest of the cuts, but I'd just make sure to cut inwards to the very base of its tail, past the dashes, and from the tip of its ear right to the dashes at the back of its head.
Cut out the rest of the shape.
While the paper pattern is still attached to the cardboard, the folds are made along the dashed lines.
I'll tell you about the dots on its ears later.
Lay the kangaroo down on something hard. Lay a ruler on each straight dashed line in turn, then lift and bend the cardboard along the edge. You can then lift the kangaroo and bend each fold backwards and forwards a few times and give the creases a hard pinch.
You're still not ready for its ears!
Now you can take off the clips and the paper pattern.
Lay it on its back on something slightly soft. A pad of newspaper perhaps, but I use my mouse-pad by my computer.
Now for its ears.
You have to imagine where those dots on the pattern would be: down the centre of each ear, but on the inside of them now.
Gently draw a wide knitting needle (the one I use says Gauge 3) or something else round and blunt along these centre lines. Then, drawing round and round in tiny circles with it, along the ears, you will see them become curved - and look like ears.
I'm sure you can work out how the model stands.
You can push out its pouch, and ease its tail upwards, as you fold your kangaroo into shape. The tail will end up 'inside out', a bit like a hollow boat. Give it a little squeeze into shape as you lift it.
Its head folds forwards (I'll leave you to draw on the eyes), and its front feet bend down.
Hopefully the soles of its feet will be nearly flat on the ground (it could be hopping and just taking off if they're not completely flat).
If the kangaroo is falling forwards too much, keep the tail pointing backwards and horizontal, but bring the back feet together. Sit the back feet on a ruler and push the tail upwards until its tip is also on the ruler's edge. Then squeeze the tail fold very hard, or rub it over with the back of a spoon until the crease is in the right place.

In general, an employer can decrease your rate of hourly pay if you are an at-will employee. However, in many states, the employer is required to first give you notice of the pay decrease. Once you are notified, the employer can pay you at the lower rate. In some states, this notice must be in writing.
Your employer cannot typically reduce your hourly wage for time you have already worked.
Under no circumstances can your employer reduce your wages so that they are below either the state or federal minimum wage.
If My Wages Have Been Reduced Unlawfully, What Can I Do?
The legal action available to you depends on what state you are in. In some states, a state agency is in charge of overseeing employment issues, and a dispute over reduced wages should be brought to their attention. In other states, there is no state agency in charge of reductions in pay, so a private action against your employer is the only way to recover lost wages.
In either scenario, you should contact an attorney familiar with employment law issues. An employment attorney can help you determine whether to file a claim with a state agency or to bring a private lawsuit, and can help you to argue your case.


Why Do Some People Always Get Lost?
Is "sense of direction" really a thing? Or is something much more mysterious at work in our minds?

Have you ever found yourself not being able to find your car in the big parking lot? Or are you someone who always knows perfectly where they are and how to get everywhere? Some people seem to know their way, even in places they've never been to before, while others get lost all the time. I was curious to find out more about how and why people get lost, because I'm really good at it.
I got lost in my neighborhood, not just once but twice.
Are natural wayfinders just geniuses, while others (like me) have some sort of directional deficiency or neurological condition? The answer is more complicated — and more amazing — than you could have imagined.
What Really IS A Sense of Direction?
When we talk about a sense of direction, or orientation, we usually mean the ability to get from one place to another: from our home to the grocery store, from work to the bar where we're meeting our colleagues. But to achieve that, we need a couple of skills that are taking place in real time.
"We talk about two simultaneous things that are happening. One is mapping — that is figuring out the map of the world around us. And the second one is localization — which is figuring out where you are inside that map," says Manu Madhav, assistant professor at the School of Biomedical Engineering and the Djavad Mowafaghian Centre for Brain Health at the University of British Columbia.
More than Five Senses
While we think of orientation as a sense, it's actually a combination of senses working together. "When you are in the real world, you have a certain expectation that as you're moving forward, your sight will tell you one thing, that things are moving backwards. That's producing a sound that will become a bit louder: that's hearing. All of those senses are individually contributing to a coherent sense...and that's what your brain interprets as moving forward," explains Madhav.
Besides smell, taste, sight, touch and hearing, we actually have two more senses: the vestibular sense or system (which has to do with our perception of our body in space), and proprioception (which has to do with the movement of muscles and joints). The vestibular system is very important in our sense of orientation. "If you open your eyes, look around, and know where you are [then] close your eyes and take five steps...you still know where you are, because your vestibular system is still going….It's simulating your position in your internal map and determining where you are," says Madhav.
Researchers say that there are special cells in our brains that have to do with space. Their function is to identify where we are at any given moment and to determine how this place relates to other places you've been. "There are neurons that would fire when I'm at this particular location. Another set of neurons that would fire when at a different location. Another set of neurons that would fire when I'm pointed in a particular direction," explains Madhav.
Where Does It Go Wrong?
There are many reasons why some people can have a bad sense of direction. "If you have attention problems, you can get lost. If you have perceptional problems and you might not be able to see colors correctly, then you might get lost. If you have memory problems, then you might get lost. There might be other reasons why you can get lost," explains Giuseppe Iaria, a neuroscientist at the University of Calgary, who studies a condition called developmental topographical disorientation, or DTD, that causes people to get lost even in places they know well. The underlying reason for this condition is an inability to form a cognitive map of their surroundings.
 According to Iaria, people with DTD are "normal people, with good and social skills; they just have a very selective deficit with orientation." Iaria runs a website called Getting Lost to help such people improve their orientation skills. In the case of people with DTD, it's not just one brain area that's affected. Instead, "it's simply a problem of functional connectivity in the brain...we have found that [certain] regions are important for special orientation and navigation...they are not well synchronized."
But the cognitive map plays a bigger role in our daily functioning. "It's the same map that's used as a memory map. You have had the experience of smelling something and the smell triggering a memory. The smell system is closely related to the hippocampus, and it's only a couple of synapses away. So smell can trigger a memory very easily," explains Madhav.
Another reason people keep on getting lost is the fact that there could be an issue with coordination between different senses. "One of the things that can happen is we get motion sickness; for example, because there is a lot of conflict between your eyes and inner ear. A conflict between the senses...can cause you to become disoriented," explains Madhav.
Moreover, a bad sense of direction can go beyond navigation because the same circuit that we use for navigation can also be used for planning and solving tasks. "Navigation, planning and memory, all of them are completely related," says Madhav.
So, bottom line: I still have no idea why I'm so bad at special orientation. But it definitely helps knowing that I'm not alone.

The fruits of the Arbutus already look very similar to the strawberries from the bed. We will introduce you to the best varieties from American and show you how to plant and care for Arbutus in the garden.
Well, are those strawberries on that tree? Even though the fruits of the Arbutus resemble red berries, the plant is not related to them. We'll tell you what this strange tree is all about.
Arbutus: origin and characteristics
The Arbutus, also known as a country berry, Hagapfel, or sea cherry, originally comes from regions like the Mediterranean, the Canary Islands, or North America. The plant has been fascinating people for a long time, as the mention in poems by Virgil and Ovid shows. In Central European gardens, however, this plant is now a real insider tip.
The Arbutus is characterized by quite slow growth, with a maximum height of about 5 to 40 meters in the open air – depending on the species. The leaves of the evergreen tree or shrub are reminiscent of those of the laurel tree.
From an age of about five years, the Arbutus is expected to bear fruit. Depending on the species, the plant blooms in winter or spring and shows its white to pink, panicle-forming bell flowers, typical of the heather family (Ericaceae), to which the tree belongs.
In spring, the red-orange strawberry-shaped berries that give the tree its name are formed, which can be harvested the following autumn. This makes the Arbutus an ideal eye-catcher in small and large gardens.
The Best Arbutus Varieties
The eleven different species of the Arbutus are divided into the old world and new world varieties according to their origin. Within the Old World species, the Arbutus unedo (Western Strawberry Tree), the Arbutus andrachne (Eastern Strawberry Tree), and the Canary Strawberry Tree (Arbutus canariensis) are the most important.
The American Strawberry Tree (Arbutus menziesii) is the best-known representative of the New World species. The Arbutus species differ optically mainly by their color and the shape of the flowers as well as the different growth height and winter hardiness.
The western strawberry tree is especially widespread in the western Mediterranean area but is also found sporadically on the Atlantic coast as far as Ireland. While most fruit trees bloom in spring, the Arbutus is an autumn bloomer and thus a real eye-catcher in the autumnal garden.
Between October and December, the plant shows white to pink, panicle-forming bell blossoms. The tree is dependent on cross-pollination. To enable the blossoms to be fertilized, you must therefore either have an Arbutus in a neighboring garden or plant two of these unusual trees in your garden.
The two to three-centimeter large fruits ripen in the following year and can be harvested in autumn during the next flowering. The western strawberry tree reaches a growth height of three to five meters. Relatively little breeding work has been done on the varieties of the plant, which is why a few special specimens are waiting for us here:
- Arbutus unedo 'Integerrima': The special feature of this variety is a particularly shrubby growth with brilliant white flowers in late autumn.
- Arbutus unedo 'Rubra': This variety offers a special color play with pink to light purple flowers in autumn.
- Arbutus unedo 'Compacta': This variety is ideal for those who want a small tree as a pot plant. It is characterized by a particularly small growth with a maximum height of one to two meters.
The Canary Strawberry Tree is originally only found in the Canary Islands, where it reaches a height of up to 15 meters. The fragrant and, unlike the Western strawberry trees, self-pollinating flowers appear in February in a white to a reddish shade. The fruits are ripe from late autumn to winter and are two to three centimeters large.
In the eastern Mediterranean region, such as in Greece or southern Albania, the Eastern Strawberry Tree is native to the region. The tree reaches a maximum height of twelve meters and the mostly white blossoms appear from February onwards. In autumn the orange-red fruits, which are about one centimeter in size, can be eaten.
The natural range of the American strawberry tree stretches along the Pacific coast of North America. Due to the strong temperature fluctuations in this region, the plant can easily cope with temperatures between -20 °C and +45 °C.
With a height of up to 40 meters and a trunk diameter of up to 150 centimeters, the New World American Strawberry Tree is the largest representative of the Arbutus. In contrast to the Old World plant, the plant blooms between April and May and forms spike-shaped inflorescences over twelve centimeters in size with small hermaphroditic white flowers. The fruits are one centimeter in diameter but smaller than the fruits.
Planting the Arbutus: location, timing, and procedure
We recommend planting your The Arbutus in spring or autumn. Summer is less suitable because the tree is sensitive to drought after planting. Unfortunately, The Arbutus is not suitable for indoor plants but needs the sun in your garden or on your balcony. Varieties such as Arbutus unedo 'Compacta' can also be grown outside in a planter. To avoid waterlogging, it is advisable not to use a coaster when cultivating in a pot.
The right location for Arbutus
Most Arbutus is best kept outdoors. Since the tree is very drought-tolerant, it feels especially comfortable in a dry and sunny corner of your garden. In winter, the American Strawberry Tree tolerates temperatures of -15 to -20 °C, all other species absolutely need winter protection and can only be planted in sheltered locations. Young Arbutus should first be cultivated in pots and left to winter without frost until the tree is sufficiently hardy at the age of five years and can be planted out.
How to plant an Arbutus
To plant your Arbutus, dig a hole one and a half times the size of the bale. Especially for trees over one and a half meters high, we recommend a wooden post as support. The tree can be fixed to the wooden post with a tree tie made of coconut rope.
However, the post and tree must not lie against each other, otherwise, the bark will be damaged by chafing. After planting, water the tree abundantly, preferably with the help of a watering rim. Especially during the next three weeks, you should now ensure a good water supply.
The tree is best watered with collected rainwater. This is good for the environment and contains less lime compared to tap water, which is good for the Arbutus.
Cutting the Arbutus
In young Arbutus, the shoot tips can be shortened somewhat in spring to promote denser growth. Sharp garden shears should be used to avoid crushing the wood. A smooth cut surface provides less surface for fungi to attack and helps to keep the tree healthy. Older trees develop best without interfering with their growth. Heavy pruning into old wood should be avoided if possible. Old wood should be removed from the crown and the branch cut back to green, i.e. still living tissue.
Both vegetative propagations via cuttings and a generative propagation of the Arbutus via the seeds in the fruits is possible. Propagation via seeds is a little more complex. The seeds swell for a few hours in water and are then stored in the refrigerator for two months, where they begin to germinate. Then the germinated seeds can be planted.
Cuttings of the Arbutus can be cut in autumn from woody but not too old shoots. The leaves of the cuttings, which are about ten centimeters long, are removed except for the top two and placed in soil. The cuttings are then covered with a transparent cover and placed in a light place at room temperature. New Arbutus then grows from the cuttings.
Are the fruits of the Arbutus poisonous or edible?
The fruits, which look like strawberries, can be harvested in autumn. The fruits of the Arbutus are edible, have a sweet-sour to sweet taste, and a slightly floury consistency.

Definition of agrochemical in English:
A chemical used in agriculture, such as a pesticide or a fertilizer.
- Even the ground water is unfit for drinking due to large-scale application of fertilizers, pesticides and agrochemicals in the tea gardens.
- These were further developed in the 1960s when agro-industrial complexes were set up to grow crops as well as producing fertilizers, pesticides, and other agrochemicals.
- However, adverse effects of high input agriculture have been recognized, as fertilizers and agrochemicals discharged from agriculture cause surface water pollution.

Milton, Florida is located in the western Florida panhandle near Pensacola. It is on US-90 and about two miles north of I-10.
Milton has a population of about 11,000, and adjacent Bagdad has another 1,500. The community is located on the Blackwater River.
Milton is one of the oldest cities in the state, having been incorporated in 1844 before Florida became a state.
Florida was still a territory and did not achieve statehood until the following year, 1845. Milton is now the county seat of Santa Rosa County.
Milton is on the banks of the Blackwater River, which served as the major transportation system for the materials that went into Milton's main industry back then, ship building.
This area of Northwest Florida was rich in timber and the naval stores that come from timber and were important to Florida's maritime trade.
Most of Milton's industrial and commercial capacity was destroyed by the Union Army during the American Civil War.
Many Milton people left the area and headed to Alabama. Most of them lost their estates and land to the Union.
The town slumbered in poverty for almost 20 years after the war. Then the railroad came to town in the 1880s.
The timber industries in the area boomed with new access into the rugged interior of the Panhandle.
After lands were cleared of timber, cotton and peanuts were planted and plantation farming became the major industry.
Two separate fires almost destroyed Milton in 1885 and 1892. An even worse fire came along in 1909 which destroyed most of the remaining surviving buildings.
The town rebuilt after those fires, and many of those buildings from the early 1900s can still be seen in the downtown section.
Bagdad is a small historic town on the south edge of Milton that has also done a good job of preserving some of their old buildings.
It began as a mill town. Today it's a quiet town where people tend to relax and enjoy the water, canoeing, sailing and fishing.
Today's Milton is a vibrant city of more than 9,000 that supports manufacturing, small businesses and farming activities.
The town is also a support center for the U.S. Naval Air Station Whiting Field, an important training facility for Navy pilots.
The combination of this and the nearby Pensacola Naval Air Station have given the entire area the nickname "Cradle of Naval Aviation."
Historic preservation is important to Milton, and the City's Downtown Historic District does a good job of keeping the place looking like the authentic and historic Old Florida that it remains to this day.
Milton is a designated Florida Main Street Community and is listed on the National Register of Historic Places.
Visitors can learn about its history at attractions such as its Museum of Local History, the Imogene Theater built in 1912, and the L&N Train Depot, honoring their important rail history.
Arcadia Mill is another historical site that has a visitor center and museum.
Its rich history as a water-powered business has evolved through its early days as a sawmill, a grist mill, a textile mill, its demise after the 1855 fire, and then its further destruction during the Civil War.
St. Mary's Episcopal Church and Rectory is on Oak Street in Milton and is an example of Carpenter Gothic church architecture.
The church was completed in 1888 and is on the U.S. National Register of Historic Places.
The church was mentioned in Frank Lloyd Wright's book, The Aesthetics of American Architecture.
It is also listed in A Guide To Florida's Historic Architecture published by the University of Florida Press.
The area offers a rich natural environment to enjoy, for all ages and activity levels. Blackwater River State Park is a popular park for camping, canoeing, kayaking, and hiking along the nature trails.
The Blackwater Heritage State Trail is a rail-trail, over 9 miles long and with paths 12 feet wide. It has the distinction of being a designated National Recreation trail.
Paved and ideal for biking, running, skating and birdwatching, there is also an unpaved shoulder for equestrian use. It winds through the middle of Milton and out to the country and over wooden bridges.
The Yellow River Marsh Preserve State Park protects one of the last tracts of wet prairie in the state including pitcher plants, and is home to almost 20 plants and animals classified as rare and endangered.
There are no recreational facilities here but is an ideal spot for nature lovers and photographers.

Separation of variables
From DispersiveWiki
Jump to navigationJump to search
Separation of variables is a classical technique to construct special solutions u to an ODE by using the ansatz for functions f and g of space and time separately. Using the fact that a function of space and a function of time can only be equal if both are constant, one can then decouple the PDE into an ODE in time and a PDE in space, which are presumably easier to solve.
In the case of linear time-translation-invariant equations, one can often express a general solution (under suitable regularity conditions) as a superposition of solutions constructed via separation of variables, for instance by using spectral theory. However this phenomenon is generally unavailable in non-linear or time-dependent contexts.
Separation of variables can be used to construct stationary soliton solutions, and is also used in the ODE method for constructing blowup solutions.


in milimeters.
 The --quick-format option lets the user select a scan area with
 predefined sizes. Valid parameters are "CD", "A5 portrait", "A5
 landscape", "Letter", "A4" and "max". The default is "max",
 which selects the largest possible area.
 The --source option selects the scan source. Valid options
 depend on the installed options. The default is "Flatbed".
 The --auto-eject option will eject a page after scanning from
 the document feeder.
CONFIGURATION FILE
 The configuration file /etc/sane.d/epkowa.conf specifies the device(s)
 that the backend will use. The current version only supports one
 scanner per EPSON backend. Possible connection types are:
 SCSI This is the default, and if nothing else is specified the
 backend software will open a given patch as SCSI device. More
 information about valid syntax for SCSI devices can be found in
 sane-scsi(5).
 PIP - Parallel Interface
 The parallel interface can be configured in two ways: An integer
 number starting at the beginning of a line will be interpreted
 as the IO address of the parallel port. To make it clearer that
 a configured IO address is a parallel port the port address can
 be preceded by the string "PIO". The PIO connection does not use
 a special device file in the /dev directory.
 USB A device file that is preceded by the string "USB" is treated as
 a scanner connected via the Universal Serial Bus. The correct
 special device file has to be created prior to using it with
 Sane. See the USB documentation for more information about how
 to set up the USB subsystem and the required device files.
FILES
 /usr/lib/sane/libsane-epkowa.a
 The static library implementing this backend.
 /usr/lib/sane/libsane-epkowa.so
 The shared library implementing this backend (present on systems
 that support dynamic loading).
ENVIRONMENT
 SANE_DEBUG_EPKOWA
 If the library was compiled with debug support enabled, this
 environment variable controls the debug level for this backend.
 E.g., a value of 128 requests all debug output to be printed.
 Smaller levels reduce verbosity.
 SANE_EPSON_CMD_LVL
 This allows to override the function or command level that the
 backend uses to communicate with the scanner. The function level
 a scanner supports is determined during the initialization of
 the device. If the backend does not recognize the function level
 reported by the scanner it will default to function level B5.
 Valid function levels are A1, A2, B1, B2, B3, B4, B5, B6, B7, B8
 and F5. Use this feature only if you know what you are doing!
SEE ALSO
 sane-scsi(5), scanimage(1), xscanimage(1), xsane(1), sane-epson(5)
BUGS
 When used with "scanimage -T" the backend hangs after sucessfully
 completing the tests. It is necessary to powercycle the scanner to get
 the communication between backend and scanner going again.
 Sometimes the scanner is not initialized correctly. The problem can be
 resolved by killing the program and restarting it again.
UNSUPPORTED DEVICES
 The backend may be used with EPSON scanners that are not yet listed
 under the list of supported devices. A scanner that is not recognized
 may default to the function level B3, which means that not all
 functions that the scanner may be capable of are accessible.
 If the scanner is not even recognized as an EPSON scanner it is
 probably because the device name reported by the scanner is not in the
 correct format. Please send this information to the backend maintainer
 (email address is in the AUTHORS file).devices. A scanner that is not

Spin lasers in the fast lane
28 October 2011
Data transmission for the Internet of tomorrow
RUB scientists develop new concept for ultrafast lasers
Electrical engineers in Bochum have succeeded in developing a new concept for ultrafast semiconductor lasers. The researchers make clever use of the intrinsic angular momentum of electrons, called spin, to successfully break the previous speed barriers. The new spin lasers have the potential to achieve modulation frequencies of well above 100 GHz in future. This is a decisive step towards high-speed data transmission, e.g. for the Internet of tomorrow. The researchers report on their results in the prestigious journal "Applied Physics Letters" of the American Institute of Physics.
Optical data transmission: the basis of our information society
Optical data transmission by semiconductor lasers is a basic prerequisite for the globally networked world and today's information society. The ever increasing degree of networking and the desire to exchange larger amounts of data are the driving force behind the development of ever faster optical data transmission systems. The maximum speed of conventional semiconductor lasers has long been a limiting factor - typical modulation frequencies are currently at levels well below 50 GHz.
Over 100 GHz possible: a barrier collapses
By using spin lasers, Bochum's researchers were able to overcome the previous limits for the modulation speed. Whereas in conventional lasers, the spin of the electrons injected is entirely arbitrary, in spin lasers, only electrons with a previously determined spin state are used. By injecting these spin-polarised electrons, the laser is forced to work simultaneously on two laser modes with different frequencies. "This frequency difference can easily be tuned using the so-called birefringence in the resonator, for example by simply bending the microlaser" said Dr. Nils Gerhardt. By coupling the two laser modes in the microresonator, oscillation with a new frequency occurs, which can theoretically reach well over 100 GHz. The researchers around Dr. Gerhardt obtained their results in the collaborative research centre 491 of the Universities of Bochum and Duisburg-Essen ("Magnetic Heterostructures: Spin Structure and Spin Transport").
Concept of a spin laser: By injecting spin-polarised electrons in semiconductor based microlasers, modulation speeds can be reached that are far superior to any conventional lasers
Oscillations in spin lasers: Relaxation oscillations, as shown in (a) mark the maximum speed achievable in conventional semiconductor lasers. By using spin-polarised electrons, oscillations are generated in the polarisation of the light field, which can be much faster than the relaxation oscillations (b). Since the oscillation lifetime can easily be tuned via the current (c), such spin lasers are ideally suited for optical data transmission


text: The Human Rights Archive recently acquired the papers of journalist and human rights activist Robert J. Cox. Born in England, Cox arrived in Argentina in 1959 to begin work at the English language Buenos Aires Herald where he would eventually rise to the position of Publisher and where he would remain until his exile in 1979. During his tenure at the Herald, Cox witnessed and reported on the turbulent events of Argentina's modern history including the growth of left wing guerrilla groups such as the Montaneros and right wing paramilitary groups such as the AAA, the short-lived but tumultuous presidency of Isabella Peron, and the massive human rights abuses of the military dictatorship which ruled the nation from 1976 to 1983. During the dictatorship Cox worked closely with human rights groups and activists including Marshall Meyer and Patt Derian whose papers are also part of the Human Rights Archive collections, to expose the crimes of the dictatorship and to help the abducted and disappeared as well as their families. Detained, jailed, and threatened, Cox and his family went into exile in 1979, but he continued to work on human rights issues in Argentina as well El Salvador and Nicaragua.

Description of the Friesian Horse population of South Africa and Namibia
AbstractData obtained from the Friesian Horse Studbook of Southern Africa and Friesian Horse Breeders\' Society of South Africa were analyzed to describe and evaluate the population regarding inbreeding and morphological body measurements. Eight different body measurements (height at withers, height of back, height of croup, body length, length of cannon forelimb and hind limb, circumference of cannon bone foreand hind limb) recorded on 232 horses were included for analyses. The pedigrees of 696 horses were used for estimation of inbreeding coefficients. A total of 25% of the horses included in the data was inbred, with inbreeding coefficients ranging from 0.07% to 27.8%. A positive trend in the average inbreeding per year was observed, but the rate of inbreeding was relatively low. Recording of pedigree information will be essential for long-term evaluation of inbreeding in the Friesian Horse and the recording of objective body measurements is recommended for inclusion in selection programs.

Volume 114 Issue 6 December 2005 pp 749-760
This paper reports on the Sub-keV Atom Reflecting Analyzer (SARA) experiment that will be flown on the first Indian lunar mission Chandrayaan-1. The SARA is a low energy neutral atom (LENA) imaging mass spectrometer, which will perform remote sensing of the lunar surface via detection of neutral atoms in the energy range from 10 eV to 3 keV from a 100km polar orbit. In this report we present the basic design of the SARA experiment and discuss various scientific issues that will be addressed. The SARA instrument consists of three major subsystems: a LENA sensor (CENA), a solar wind monitor (SWIM), and a digital processing unit (DPU). SARA will be used to image the solar wind-surface interaction to study primarily the surface composition and surface magnetic anomalies and associated mini-magnetospheres. Studies of lunar exosphere sources and space weathering on the Moon will also be attempted. SARA is the first LENA imaging mass spectrometer of its kind to be flown on a space mission. A replica of SARA is planned to fly to Mercury onboard the BepiColombo mission.

Ever have that Oh Sh!t – Stomach Churning – Career Ending moment where you accidently deleted something you shouldn't?
Why is Delete right beside Rename!
Because even Admins make mistakes, it is a best practice to protect every critical object in AD from accidental deleting something. How you ask?
You could do it one of two ways. First the slow (manual) way. Simply select the properties of any critical AD object (Computer, Group, Organizational Unit, User, etc). Then select the Object tab and check the "Protect object from accidental deletion" box.
If you are anything like me, you did this for a handful of objects and thought "this is dumb… how can I automated this?" Pretty easily it turns out. Which brings us to method number 2 – the PowerShell way.
Get-QADObject -searchroot 'DC=Test,DC=local' -type 'group' -SizeLimit 0|
Add-QADPermission -Deny -Account 'EVERYONE' -Right 'Delete,DeleteTree' -ApplyTo ThisObjectOnly
As a note, this script makes use of the Quest AD cmdlets for PowerShell. It will recursively go through your -SearchRoot parameter (in this case, the entire domain) and prevent users from deleting the object.
