The Richboro Elementary Meadow Project
Students in the Richboro Elementary Ecology Club have been planting a meadow each year since 2008. We were the first school in Council Rock School District to do so, and our project has inspired the District to plant four acres of meadows at several other Council Rock school locations.
Why plant meadows? Meadows provide habitats for more insects and other animals than green lawns. The first year we planted the meadow, we found two praying mantids had moved in! Additionally, meadows do not need to be mowed more than once a year, so they save fossil fuel. Below are photos and descriptions of our current meadow as well as meadows from previous years.
The Fourth Planting of
Richboro Elementary School's Meadow
Students in the Richboro Elementary School Ecology Club planted its fourth meadow this spring. Students sowed the flower seeds harvested last fall in the newly prepared plot. Additional native seeds, including sunflower and asters, were planted. Students and teachers look forward to seeing what surprises await when returning to school in the fall.
The Third Planting of
Richboro Elementary School's Meadow
The Ecology Club at Richboro Elementary School planted its meadow for a third growing season this April. Using seeds harvested from the meadow last fall, the club members, ranging from grades two through five, took turns planting seeds in a grid-like pattern across the meadow plot. Sunflower seeds were pushed into the ground with planting sticks, and the soil was raked to cover the seeds. As the club ended, the clouds gathered and watered the meadow, as if on cue. We look forward to watching our garden bloom as the seasons turn.
Richboro Elementary School's Meadow
The Ecology Club at Richboro Elementary School planted its meadow for a second growing season this April. The club, with over 40 students and 5 teachers, worked together to sow seeds on a drizzly, windy day. The seeds had been harvested by the students last fall from the meadow's first dried flowers. The charming sign, including drawings by 13 children, will be posted at the front of the meadow.
Richboro Elementary School's Meadow Blooms
and Seeds are Harvested
Last spring the Ecology Club at Richboro Elementary School planted seeds to create a meadow in the front of the building. Not certain how successful the meadow would be, the club members were greeted at the beginning of this school year by a surprisingly full field of colorful blooms. This fall the flowers matured to produce seeds. To complete the cycle, the Ecology Club plans to plant the seeds next spring.
The Earth Laughs in Flowers
Richboro Elementary School's Meadow Project
The Ecology Club at Richboro Elementary School planted a meadow for their final big project of the school year. Ecology Club students pulled out clumps of grass, and then teachers gave students seeds to plant in the plot. The students zig-zagged their way across the plot to ensure even coverage of the seeds. At the end of the day, each child received a small bag of seeds to plant at home with the saying, "The Earth Laughs in Flowers." The seeds had been sorted and packaged by students in the Autistic Support classes at Richboro Elementary.
The flowers hopefully will grow throughout the summer. In addition to adding beauty to the school, the meadow will reduce the fossil fuel needed to mow the grass all summer and will help insects gain a new home. The students and teachers look forward to seeing a wildflower meadow in full bloom at the beginning of the new school year in September.

What is a Pseudolite?
A pseudolite (or pseudo-satellite) is any device that performs a specific task that would otherwise require a satellite. So, for example, a dedicated transmitter might be deployed to extend the reach of a GNSS to areas where the satellite signals are either blocked or jammed, and there has been considerable success with deployment of pseudolites to extend GPS coverage indoors. These are relatively simple devices that only transmit the coarse acquisition code.
Pseudolites are also used to simulate future GNSS satellites in a real-world environment as well as for robotic guidance in space exploration.
A single-channel GNSS simulator (or signal generator) can be used as a pseudolite, particularly in the research and development arena. However, care needs to be taken when operating powerful transmitters within GNSS bands. Clearly, highly sensitive GNSS receivers designed to capture minute signals from distant satellites will not react well to high-power transmissions on their receiving frequencies.

Both「目的」and「目標」have a common meaning which is "goal", but what is the difference?
When can we use one but not the other?
I would think of a basic example.
I want to become better at shooting the basketball. => 目的
I think 目的 is a high level image, global image of a goal. 目標 is more achievement like low level goal, usual can be quantified and explicit that will define the concrete steps to the 目的.
I think it boils down to the difference in English between "purpose" and "goal". A goal is something finite you hope to achieve. A purpose is like a motivation for why you do something. Often they will overlap, but not always. Having a finite goal kind of implies that you have a motivation. However, the converse -- having a motivation implies you have a finite goal -- is not necessarily true.
So the same with the Japanese words. If you have a

When characterizing materials such as Metals and Plastics in LS-DYNA, most constitutive models provide a yield criteria that accounts for a 3D state of stress which reduces to a uniaxial yield stress in 1D. This allows us to directly input the true stress-strain curve from a one-dimensional state of stress testing such as in uniaxial testing which then can be used for any 3D problems. One important consideration in the usage of such one-dimensional testing data is the phenomenon called necking which occurs in both Metals and Plastics. It is well known that post-necking stress state is no longer uni-axial but is a 3D state of stress. This limits us to use uniaxial information only upto necking and use some sort of iterative process to characterize the post-necking behavior. The first task therefore is to identify the necking point on a uni-axial true stress-strain curve. This is done by plotting the true stress-strain curve against its derivative. The intersection point of these curves is the necking point. When this curve overlay is done using the raw test data, which is sampled at a high frequency, the derivative may be extremely noisy and this may provide multiple intersection points. A sample of such noisy overlay is shown here:
To overcome this, it is usually recommended to digitize the raw curve using anywhere from 10-100 equi-distant points which provides a very smooth derivative of the true-stress-strain curve ensuring a unique point of intersection (necking point). A digitized curve using the raw test data is shown here.

Rongme Ngatra of the Chola Mountains in Garze, Sichuan
Rongme Ngatra is the highest peak of the Chola Mountains in the Kham region of western Sichuan, China. The peak's name in Mandarin Chinese is Que Er Shan or Chola Mountains (Chinese: 雀儿山; pinyin: Què'ér Shān) also the same name as the entire range, which has led to some translations of the mountain peak to Chola Mountain. At 6,168 metres (20,236 ft), the mountain is the highest peak in the Chola Mountains, as well as the second highest in the greater Shaluli Mountains after Ge'nyen.[2]The mountain peak is flanked by glaciers to the north and east. The north glacier terminates at 4,100 metres (13,500 ft) above sea level, just above the nearby lake Yihun Lhatso.[3] Rongme Ngatra can be accessed from the town of Manigangoin Dege County, Garze Prefecture.

How to make Roman coins
Ebi-kun has had an interest in ancient Rome and gladiators recently so we decided to make some Roman coins.
We used a basic salt dough and added brown food colour.
Salt dough recipe
2 cups of plain flour
1/2 cup salt
1/2 - 3/4 cup hot water
+ brown food colour
Just throw everything into a bowl and mix until you get a dough. Then take a small lump of dough, roll it into a ball the squash it flat. We experimented with different tools but found the end of a paintbrush worked best for engraving the numbers.
We baked them at 180c for 10 minutes then turned them over and gave them another 5 minutes.
Once they had cooled we painted them with varnish, Ebi-kun is a bit heavy handed with the varnish so some came out a bit splogy.

Why table tennis is the best sport in the world
Table tennis is the popular sport in the world
Why is table tennis? There are thousands of other sports out there, but table tennis has been one of the best liked and most loved sport by many athletes and sports lovers in the world. It relatively known as the most rapid competitive sport around the globe, as well as being one of the simplest ones to learn and play. What makes table tennis great for the brain is that it is a very challenging sport, in terms of thinking and problem solving, which will give you and your brain hours of enjoyable and stress-relief.
9 reasons why is table tennis a popular sport
1) Good for your brain
ping pong is good for your brain
Table tennis is a challenging sport for several reasons. For example, it requires a great deal of mental acuity. The game involves a lot of decision making and problem solving skills, both on and off the court. This type of thinking and problem solving is good for the brain, which will be the mechanism that helps your brain to process quickly and efficiently when it comes to making decisions. All of these great things are the reason why table tennis is the perfect sport to learn and play, for anyone from any age group and in any walk of life.
2) Suitable for all ages
In addition to the great things about table tennis, the game itself is great for any age group. You can play table tennis even if you are still a child, and there are even some kids' versions that you can buy nowadays. At any age, you can dive in and have some fun, even if you are old. That is because the sport itself does not discriminate based on age or gender.
3) Less expensive
The best reason to learn and play table tennis is the money. It's a very inexpensive sport, especially when you consider all of the equipment you need (or you don't need). A good set consists of: a racket, four ping-pong balls, a net and a portable table – thanks to sportypong's review of the cheapest ping-pong tables. Now, add up the cost of those things over an entire season of play and you may come up short.
4) Perfect exercise
What is the one thing you will benefit the most from playing? Of course, the obvious: the game itself. Because it utilizes all of your body metabolism, you are constantly working out your muscles. This is a great benefit and one you will notice right away. If you are someone who can't stand long workouts, then table tennis can be a great choice for you.
5) Good for cardiovascular
It is also a great cardiovascular workout. Table tennis requires a great deal of jumping and spinning, as well as a great deal of running and moving around. All of that running and moving around gets your heart pumping, which can be great for your heart. And, since it is a stationary sport, there is absolutely nothing that can go wrong.
6) Play anywhere, even play alone
practice table tennis alone
If you don't have access to a table tennis robot, don't worry. You can still play this great sport. You just won't have to use a machine. Because you play the sport where there is no contact, it is extremely safe to play anywhere, even play alone.
7) The mental game
One last reason to play the great table tennis sport, and one that is often overlooked. The mental game. The better you get at this, the better you will do in any competition. That includes life. By taking the time to think correctly, you can do things with your body that is almost impossible in many sports. Playing table tennis helps your brain work, which is something that is extremely important and useful.
8) Low club fees
It is impossible to talk about these reasons why table tennis is the best sport without talking about money. The cost of joining a club and consistently using your racket for hours at a time can quickly add up. If you don't have the money to join a club, don't worry. You can also buy your own paddle, ball and other accessories. Not only is it cheaper than buying them from someone else, but you can find discount prices if you shop around online.
9) Finally, let's discuss winning
You cannot measure this aspect of the sport in dollars and cents. You have to put into consideration the fact that you are constantly getting points. These points add up quickly and overtime is even more of an all-timer. Therefore, you want to rack up those points because your chances of winning are very good. This means playing as often as possible, especially when you are a good player.
There are many reasons why table tennis is the best sport to play. However, you need to be honest with yourself and know why you play. Once you are able to pinpoint why you play, then you can choose how you are going to play. Maybe you are a great blocker, so now you can play that position. Maybe you are a great rebounder, so now you can play that position too.

2.4. Blockade Interaction in a Magnetic Field
The interaction between Rydberg atoms is strongly influenced by external electric and magnetic fields. A small magnetic field for instance lifts the Zeeman degeneracy and thus strengthens the Rydberg blockade, especially if there is a non-zero angle between the interatomic and the quantization axis. This has been discussed in M. Saffman, T. G. Walker, and K. Mølmer, "Quantum information with Rydberg atoms", Rev. Mod. Phys. 82, 2313 (2010). Here we show how to reproduce Fig. 13 using pairinteraction. This Jupyter notebook and the final Python script are available on GitHub.
As described in the introduction, we start our code with some preparations. We will make use of pairinteraction's parallel capacities which is why we load the multiprocessing module if supported by the operating system (in Windows, the module only works with methods defined outside an IPython notebook).
%matplotlib inline
# Arrays
import numpy as np
# Plotting
import matplotlib.pyplot as plt
# Operating system interfaces
import os, sys
# Parallel computing
if sys.platform!= "win32": from multiprocessing import Pool
from functools import partial
# pairinteraction :-)
from pairinteraction import pireal as pi
# Create cache for matrix elements
if not os.path.exists("./cache"):
cache = pi.MatrixElementCache("./cache")
We begin by defining some constants of our calculation: the spatial separation of the Rydberg atoms and a range of magnetic field we want to iterate over. The units of the respective quantities are given as comments.
distance = 10 # µm
bfields = np.linspace(0, 20, 200) # Gauss
Now, we use pairinteraction's StateOne class to define the single-atom state \(\left|43d_{5/2},m_j=1/2\right\rangle\) of a Rubudium atom.
state_one = pi.StateOne("Rb", 43, 2, 2.5, 0.5)
Next, we define how to set up the single atom system. We do this using a function, so we can easily create systems with the magnetic field as a parameter. Inside the function we create a new system by passing the state_one and the cache directory we created to SystemOne.
To limit the size of the basis, we have to choose cutoffs on states which can couple to state_one. This is done by means of the restrict... functions in SystemOne.
Finally, we set the magnetic field to point in \(z\)-direction with the magnitude given by the argument.
def setup_system_one(bfield):
 system_one = pi.SystemOne(state_one.getSpecies(), cache)
 system_one.restrictEnergy(state_one.getEnergy()-100, state_one.getEnergy()+100)
 system_one.restrictN(state_one.getN()-2, state_one.getN()+2)
 system_one.restrictL(state_one.getL()-2, state_one.getL()+2)
 system_one.setBfield([0, 0, bfield])
 return system_one
To investigate the \(\left|43d_{5/2},m_j=1/2;43d_{5/2},m_j=1/2\right\rangle\) pair state, we easily combine the same single-atom state twice into a pair state using StateTwo.
state_two = pi.StateTwo(state_one, state_one)
Akin to the single atom system, we now define how to create a two atom system. We want to parametrize this in terms of the single atom system and the interaction angle.
We compose a SystemTwo from two system_one because we are looking at two identical atoms. Again we have to restrict the energy range for coupling. Then we proceed to set the distance between the two atoms and the interaction angle.
To speed up the calculation, we can tell pairinteraction that this system will have some symmetries.
def setup_system_two(system_one, angle):
 system_two = pi.SystemTwo(system_one, system_one, cache)
 system_two.restrictEnergy(state_two.getEnergy()-5, state_two.getEnergy()+5)
 if angle == 0: system_two.setConservedMomentaUnderRotation([int(2*state_one.getM())])
 return system_two
Now, we can use the definitions from above to compose our calculation.
def getEnergies(bfield, angle):
 # Set up one atom system
 system_one = setup_system_one(bfield)
 # Calculate Zeeman shift
 zeemanshift = 2*system_one.getHamiltonian().diagonal()[system_one.getBasisvectorIndex(state_one)] # GHz
 # Set up two atom system
 system_two = setup_system_two(system_one,angle)
 # Calculate blockade interaction
 eigenenergies = (system_two.getHamiltonian().diagonal()-zeemanshift)*1e3 # MHz
 overlaps = system_two.getOverlap(state_two)
 blockade = 1/np.sqrt(np.sum(overlaps/eigenenergies**2))
 return blockade
With a little boiler-plate, we can then calculate and plot the result with matplotlib.
plt.xlabel(r"$B$ (Gauss)")
plt.ylabel(r"Blockade (MHz)")
if sys.platform!= "win32":
 with Pool() as pool:
 energies1 = pool.map(partial(getEnergies, angle=0), bfields)
 energies2 = pool.map(partial(getEnergies, angle=_URL_, bfields)
 energies1 = list(map(partial(getEnergies, angle=0), bfields))
 energies2 = list(map(partial(getEnergies, angle=_URL_, bfields))
plt.plot(bfields, energies1, 'b-', label=r"$\theta = 0$")
plt.plot(bfields, energies2, 'g-', label=r"$\theta = \pi/2$")
plt.legend(loc=2, bbox_to_anchor=(1.02, 1), borderaxespad=0);

The EUR 27 million project required LCW Consult (LCW) to design a pre-stressed, concrete cantilever bridge between Lisboa and Coimbra, with a 250-meter main span at 140 meters above the riverbed, to ensure transparency of the Ceira Valley. To accommodate the large main bridge span, optimize aerodynamics, and ensure geometry control using balanced cantilever construction, LCW needed integrated bridge design and analysis software.
LCW used Bentley PowerCivil and RM Bridge to study seven different structural options to determine the most efficient design and construction solution. Bentley software helped to facilitate communication among the teams and enabled LCW to model and evaluate aerodynamic conditions and geometrical shape to reduce unforeseen adjustments during construction and to ensure optimal structural performance of the bridge.
The modeling and analysis capabilities of RM Bridge allowed LCW to study different structural scenarios and determine the most efficient solution in terms of cost, risk, and safety of the project. Using RM Bridge resulted in a 25 percent reduction in design time compared to conventional spreadsheet analysis. Integrating Bentley software improved team collaboration and reduced engineering hours, yielding a cost savings of approximately EUR 52,000. In addition, the RM Bridge code library enabled the team to easily comply with Eurocodes.
LCW used Bentley engineering software for design, analytical, and construction modeling to optimize aerodynamics and ensure geometry control for the large main span bridge to be built by the cantilever method. Integrating PowerCivil and RM Bridge facilitated collaboration between the engineering office and the field, increasing the precision of geometry modeled to reduce unforeseen adjustments during construction. The flexibility and interoperability of Bentley software ensured optimal structural design and performance for the EUR 27 million bridge project.

When you spin an asymmetrically weighted, 2D disk-shaped top, the heavy part actually rises to the top. Why is this?

In the second video it shows that this is because of friction but trying this on a frictionless surface won't do much: The disk will go up and down and still the heavy part will be on the top.

I think the solution has more to do with the tennis racket effect (see: _URL_
Let me clarify the disk with hole in it has two stable axes of rotation and one unstable one. The unstable one is through the hole and the stable one is across (below in green) and normal to the disk.
Axes Def
I have confirmed that without friction (and from the videos in the link above) when the disk is spun on the unstable axis, it will perdiodically flip. This is what caused it to flip when the disk was falling without friction.
The additional nuiance here is the once it is on the "upsidedown" oriention and friction is present then the unstable axis becomes stable.
If the hole spans from the center to the edge of the disk, then the center of gravity is at $$ \vec{c} = (0,-\frac{R}{6},0)$$ where $R$ is the outside radius of the disk. The principal moments of inertia about the center of mass are $$ \begin{aligned} I_{XX} & = m \left( \frac{\ell^2}{12} + \frac{29 R^2}{144} \right) \approx 0.2 m R^2 \\ I_{YY} & = m \left( \frac{\ell^2}{12} + \frac{5 R^2}{16} \right) \approx 0.31 m R^2 \\ I_{ZZ} & = m \left( \frac{37 R^2}{72} \right) \approx 0.51 m R^2 \end{aligned} $$
where $\ell$ is the thickness of the disk. Since $I_{YY}-I_{XX} = \frac{8}{37} I_{ZZ}$ this means that the y direction is the medium inertia value, x the minimum and z the maximum. Hence the instability about the y axis according to the Tennis Racket Effect.
I am working to qualify the above statement and I am going to update this post with my findings.

may you please explain why the axis through the hole is unstable, I would say it should be the one on the x-axis because it is not symmetrical. – Mhmd Dec 31 '13 at 12:43
_USER_ Any rigid body has three principal moments of inertia of different values. Rotation about the smallest and largest direction is stable, whilst rotation about the medium value is unstable. This is the tennis racket effect. – ja72 Dec 31 '13 at 16:17
I have added a little more about the mass moments of inertia on the post. – ja72 Dec 31 '13 at 16:58
The tennis racket effect/theorem can be accurately understood by the Poinsot-Binet Energy Ellipsoid. More reference is in Goldstein – Torsten Hĕrculĕ Cärlemän Dec 31 '13 at 17:24
I) Here we will give a qualitative rather than quantitative analysis. Consider first the axially symmetric 3D tippe top, which means that there will be two principal axis with maximal moment of inertia. (If we wish, we can for simplicity model the top as a spherically symmetric ball, with a heavy point mass off the geometric center $O$.) Empirically, we observe to a first approximation that:
 1. The angular vector $\vec{\omega}$ is mostly vertical and completes a small precession for each revolution of the top. (Let's assume that $\vec{\omega}$ is upwards rather than downwards.)
 2. The rotation of the top is around a point $Q$ somewhere between the geometric center $O$ and the center of mass $C$.
 3. The point $P$ of contact completes a small circular orbit for each revolution of the top.
 4. The top is mostly rolling without sliding. In other words, to a first approximation, it is static friction rather than kinetic friction, and hence the mechanical energy is conserved.
The angular momentum vector $\vec{L}$ will mostly point upwards but tilted a bit to the same (opposite) side as $C$ iff $O$ is above (below) $C$. In other words, the angular momentum vector $\vec{L}$ completes a small precession for each revolution of the top. We will assume that this precession of $\vec{L}$ (and the corresponding net torque needed for this precession) remains very small during the entire inversion process.
Now the torques of gravity and the normal force work in unison to increase the precession of $\vec{L}$. The cancellation of this torque can only come from the friction force acting in the same direction (horizontally speaking) as where the center of mass $C$ is.$^1$
Naturally, due to an imperfect rolling motion, the friction force will then tend to slide the point of contact in the direction of the friction force, thereby raising the center of mass $C$. (Del Campo showed that sliding friction must play an essential role in the inversion process, cf. Ref. 1. Of course sliding friction is also responsible for that the top eventually comes to rest and looses its mechanical energy.)
II) The asymmetric 2D discs$^2$ works similarly, although now the rotation will mainly be around the unstable principal axis with intermediate moment of inertia, leading to the tennis racket/Dzhanibekov effect, as correctly pointed out by ja72 in his answer, see also e.g. this Phys.SE post and links therein. In situations without friction, the tennis racket/Dzhanibekov effect explains the last unresolved part of the solution video.
 1. Richard J. Cohen, The tippe top revisited, _URL_ (hat tip: Leonida)
$^1$ Note that the friction torque argument in this Basic Saucer Physics 101 video seems to lead to the opposite effect where the center of mass $C$ gets lowered (rather than raised).
$^2$ The geometric details of the asymmetric 2D discs is to a large extent irrelevant for the effect.

I have a diagonal line and I have also a circles having a 100 meters in distance. The problem is that the circles are not really to the center of the line. I know this is quiet easy but I'm just confused on how to do it.. Could someone help me how to put the circles at the center of the line?
Here's what I've tried so far :
public void paint(Graphics g)
 Graphics2D g2d = (Graphics2D) g;
 int x0_pixel = 0;
 int y0_pixel = 0;
 int x1_pixel = getWidth();
 int y1_pixel = getHeight();
 int x0_world = 0;
 int y0_world = 0;
 double x1_world = 2000; // meters
 double y1_world = 1125; // meters
 double x_ratio = (double) x1_pixel / x1_world;
 double y_ratio = (double) y1_pixel / y1_world;
 int xFrom = 0;
 int yFrom = 0;
 double xTo = x1_world;
 double yTo = y1_world;
 int FromX_pixel = convertToPixelX(xFrom, x_ratio);
 int FromY_pixel = convertToPixelY(y1_pixel, yFrom, y_ratio);
 int ToX_pixel = convertToPixelX((int) xTo, x_ratio);
 int ToY_pixel = convertToPixelY(y1_pixel, (int) yTo, y_ratio);
 g2d.drawLine(FromX_pixel, FromY_pixel, ToX_pixel, ToY_pixel);
 double theta = Math.atan(yTo / xTo);
 int len = (int) Math.sqrt(xTo * xTo + yTo * yTo);
 int interval = 100;
 final double cosTheta = Math.cos(theta);
 final double sinTheta = Math.sin(theta);
 for (int distance = xFrom; distance <= len; distance += interval)
 double distance_x = distance * cosTheta;
 double distance_y = distance * sinTheta;
 int x_circle_pixel = convertToPixelX(distance_x, x_ratio);
 int y_circle_pixel = convertToPixelY(y1_pixel, distance_y, y_ratio);
 g2d.drawOval(x_circle_pixel, y_circle_pixel, 50, 50);
private static int convertToPixelY(int y_offset, double y_world, double y_ratio)
 return (int) (y_offset - (y_world * y_ratio));
private static int convertToPixelX(double x_world, double x_ratio)
 return (int) (x_world * x_ratio);

Some comments and descriptions about what your code is doing would help a lot. Also an SSCCE would offer your best hope for a quick helpful answer. – Hovercraft Full Of Eels Oct 11 '11 at 2:11

When you draw an oval, the first two parameters are the upper-left corner of the rectangle that holds the oval. The next two parameters are the width and height of this same bounding rectangle. Your current code places the upper-left corner on the line itself, but what you actually want is that the center of the bounding rectangle be placed on the line. The solution to your problem is to simply shift the upper-left corner over by 1/2 the diameter. Your code should have something like so:
public class GraphicsFoo extends JPanel {
 // avoid using magic numbers:
 private static final int CIRCLE_DIAMETER = 50;
 // override a JComponent's paintComponent method, not its paint method
 protected void paintComponent(Graphics g) {
 Graphics2D g2d = (Graphics2D) g;
 // make your graphics smooth
 //...
 final double cosTheta = Math.cos(theta);
 final double sinTheta = Math.sin(theta);
 // *** here's the key: ***
 x_circle_pixel - CIRCLE_DIAMETER / 2,
 y_circle_pixel - CIRCLE_DIAMETER / 2,

sorry for the late response, actually my problem is the only part in drawing the oval and you give me the exact code for that.. tnx.. it works.. I accept your answer.. ;-) – sack Oct 11 '11 at 10:33

Authors: Judi A. Turner, M.D., Ph.D. et al
Anesthesiology published on 4 2016.
Background: This multicenter, retrospective study was conducted to determine how resident performance deficiencies affect graduation and board certification.
Methods: Primary documents pertaining to resident performance were examined over a 10-yr period at four academic anesthesiology residencies. Residents entering training between 2000 and 2009 were included, with follow-up through February 2016. Residents receiving actions by the programs' Clinical Competency Committee were categorized by the area of deficiency and compared to peers without deficiencies.
Results: A total of 865 residents were studied (range: 127 to 275 per program). Of these, 215 residents received a total of 405 actions from their respective Clinical Competency Committee. Among those who received an action compared to those who did not, the proportion graduating differed (93 vs. 99%, respectively, P < 0.001), as did the proportion achieving board certification (89 vs. 99%, respectively, P < 0.001). When a single deficiency in an Essential Attribute (e.g., ethical, honest, respectful behavior; absence of impairment) was identified, the proportion graduating dropped to 55%. When more than three Accreditation Council for Graduate Medical Education Core Competencies were deficient, the proportion graduating also dropped significantly.
Conclusions: Overall graduation and board certification rates were consistently high in residents with no, or isolated, deficiencies. Residents deficient in an Essential Attribute, or multiple competencies, are at high risk of not graduating or achieving board certification. More research is needed on the effectiveness and selective deployment of remediation efforts, particularly for high-risk groups.

Why Your Microgreens Smell or Have Mold & 6 Easy Fixes
Please share our content!
Moldy Microgreens
Are you experiencing a foul odor coming from your microgreens that you can't quite ignore? This smell not only makes for an unpleasant growing experience but if you are a commercial microgreens grower, then the microgreens can't be sold to customers. What a waste of microgreens!
So, why do the microgreens smell? Many reasons could be causing the microgreens to be smelling foul. Some of the reasons are root or stem rot, mold, humidity and temperature issues, and chemicals. All these problems relate to each other, and it's vital to eliminate any possible cause for the production of healthy and tasty microgreens.
Here are six surefire ways to get your microgreens healthy and smelling great in no time:
 1. Lower the seed density.
 2. Avoid overwatering.
 3. Water from the right angles.
 4. Optimize the temperature and humidity.
 5. Eliminate mold.
 6. Sanitize the growing medium.
The main culprits of smelly microgreens are usually mistakes gardeners make that go unnoticed. In this article, we will discuss six practical ways to prevent microgreens from smelling and we will find out more about what makes them smell bad in the first place.
Practical Fixes to Smelly Microgreens
Smelly microgreens are a nuisance and they also bring huge losses in profit. To avoid growing smelly microgreens, here are the fixes you can implement:
1. Lower the Seed Density
If seeds are tightly clustered together, air deficiency and poor drainage occur. Some of the plants could grow, but they'll end up being too congested. This could prompt root rot, which gives off terrible odors.
If you are having trouble with determining how much seed to put into your container, take a look at this great article from Home Microgreens – Seed Calculator.
2. Avoid Overwatering
Overwatering leads to the deficiency of oxygen and prompts root rot. But how much water is enough?
It's simple. The soil or other growing media should be moist, not wet. Experiment with different moderate amounts to determine the most favorable levels. Use this Soil Moisture Sensor from our Best Garden Tools page to determine the optimal amount in a specific growing area.
Simply check the microgreen plants every day and water if necessary. A good water sprayer or a self-watering system might also help if you are still struggling. Check out our True Leaf Market Products page for some helpful links to affordable options!
3. Water from the Correct Angles
While it's okay to water from the top when the seeds haven't germinated, that's not always the case for sprouted microgreens.
If microgreens have some leaves, start spraying water from the bottom. If plants are sprayed from the top, the dense stems will trap moisture and cause musty smells, which can escalate to plant rot.
4. Optimize Temperature and Humidity
In order to optimize temperature and humidity for microgreens, think about how this is accomplished in the home.
Humidification for plants occurs when they are watered. However, it is recommended to use a dehumidifier and an air fan to control humidity levels and promote aeration. Many microgreen farmers fail to optimize humidity and temperature, and it costs them big time. Be ahead of the game and grow fresh, smell-free microgreens.
5. Eliminate Mold
If mold is noticed that is making microgreens smelly, eradicate it before it spreads. Here are two ways to get rid of mold on microgreens:
 1. Make a weak mixture of water, white vinegar, and hydrogen peroxide to spray onto the plants.
 2. Place the microgreens in sunlight. Mold will dry up and die.
See how to remove and avoid mold from microgreens by following this advice from Urban Farmer Curtis Stone:
HOW TO: Avoid and Remedy Mould On Microgreens
6. Sanitize the Growing Medium
Microgreens might take in chemicals that lead to smells. To avoid this, ensure that the components of the growing medium are well researched.
Most organic microgreen growing pads are expensive. However, they are worth the price since they produce healthy, tasty greens with little issues when growing.
Also, use food-safe plastics to ensure no chemicals like lead from PVC are absorbed by microgreens to influence their smell.
Isaiah 41:10
Why Your Microgreens Smell
Now that you're aware of how to stop microgreens from smelling bad, it's important to understand what causes microgreens to smell. Depending on set up, the microgreens could be experiencing any of the following issues.
Root or Stem Rot
Damping Off Seedlings
Root and stem rot can be caused by heat stress, high humidity and lack of ventilation. All these factors go hand in hand because high temperatures plus high relative humidity without consistent airflow lead to air deficiency.
Sometimes, root rot is also caused by damping-off — a disease that's more prevalent in wet conditions.
If a swampy smell is noticed, then inspect the set up immediately. Roots or stems will begin rotting if the issue is not remedied quickly. If this happens, then the entire batch of microgreens will need to be thrown away because they are no longer safe to consume.
Check plants' stems and roots for discoloration if rotting is suspected. However, if microgreens' roots and stems seem to be turning into somewhat thin, thread-like structures, then they have rotted.
Do the microgreens smell like a poorly ventilated basement? This can mean that mold has begun growing. Mold is an enemy to humans everywhere. If it can degrade a strong ceiling, imagine the harm it can cause to microgreen plants.
Mold development in microgreens can be caused by excess humidity plus inadequate aeration. To prevent mold growth, ensure optimal humidity, temperature, and ventilation for microgreen growing.
But could mold be mistaken for root hairs? People make this mistake all the time. They end up throwing away perfectly healthy microgreens because they think root hairs are mold.
Here's how to distinguish mold from root hairs:
 - Mold affects parts of the batch while root hairs are even throughout the entire batch.
 - Mold appears towards the top while root hairs only appear at the bottom of the stem.
 - When water is poured on them, root hairs jump a bit while mold does not.
High Humidity Plus High Temperatures
Many novice microgreen growers think that a sauna effect, like that of a greenhouse, is the best way to grow microgreens. However, this is not true, and this could be the reason microgreens are smelling.
While ideal temperatures and humidity for growing different microgreens are somewhat particular to the specific species, 64 °F to 75 °F in temperature plus 40% to 60% relative humidity is favorable for most microgreens.
High humidity swells the plants and brings a musty odor to them. If it stays like that for a long time, fungal infections will occur that can worsen to root rot.
The cause of smelly microgreens could be that the growing medium used was made with chemicals of which the gardener wasn't aware. Furthermore, it could be the plastic pots in which plants are growing that include harmful chemicals. Either way, the chemicals might be causing microgreens to smell.
The medium in which plants are grown is really important. Always buy seeds, substrates, and plastics from certified sellers. They may be slightly more expensive than the non-certified ones, but it's worth the investment to be safe. Not to mention, buying from non-certified sellers is illegal and customers can be held liable by the law.
In Conclusion…
Microgreens are not like the mature plants grown in an open farm or greenhouse. They are delicate and susceptible to the slightest pathogens and harsh conditions. This may bring up undesirable smells in them.
Now that you understand what might be causing your microgreens to smell, you can use the above fixes to curb them and also learn to avoid them for good.
If you would like to get started growing microgreens or need a boost in your supplies, we highly recommend checking out our affiliate at True Leaf Market. They have microgreen seeds, supplies, starter kits, and anything else you can think of to make your production a success!

Motion-correlated flow distortion and wave-induced biases in air–sea flux measurements from ships
- 1School of Earth and Environment, University of Leeds, Leeds, UK
- 2National Oceanography Centre, Southampton, UK
- anow at: Centre for Applied Geosciences, University of Tübingen, Germany
Abstract. Direct measurements of the turbulent air–sea fluxes of momentum, heat, moisture and gases are often made using sensors mounted on ships. Ship-based turbulent wind measurements are corrected for platform motion using well established techniques, but biases at scales associated with wave and platform motion are often still apparent in the flux measurements. It has been uncertain whether this signal is due to time-varying distortion of the air flow over the platform or to wind–wave interactions impacting the turbulence. Methods for removing such motion-scale biases from scalar measurements have previously been published but their application to momentum flux measurements remains controversial. Here we show that the measured motion-scale bias has a dependence on the horizontal ship velocity and that a correction for it reduces the dependence of the measured momentum flux on the orientation of the ship to the wind. We conclude that the bias is due to experimental error and that time-varying motion-dependent flow distortion is the likely source.

import old database in new schema with mysql and rails
posted by Matthias Frick in Ruby on Rails / 4 Comments
In this tutorial I will show you how you could import an old database into a new schema with mysql and rails. I will explain the process with an example scenario.
Imagine you have an old php project with an old database schema and you want to completely refactor this project. Firstly you want to use rails instead of php and create a new rails project with the standard rails conventions. Secondly you want to restructure the old database into a new scheme without losing data and make it more "railsish". You just have a mysql dump of your old database.
Old database:
You have a mysql database with a few tables:
 - "Person" with: pid (bigint 20), uid (varchar 8), firstname (varchar 40), lastname (varchar (50), mail (varchar 40), isfemale (tinyint 4)
 - "Work" with: wid (bigint 20), headline (varchar 250), text_facts (text), text_long_facts(text), pub_date (date), hyperlink (varchar 200)
Now you want to change this scheme to the following one:
New database:
Your new database contains the following tables:
 - "users" with: id (int 11), first_name ( varchar 255), last_name (varchar 255), email (varchar 255), isfemale (tinyint 1)
 - "projects" with: id (int 11), title (varchar 255), teaser (text), description (text), published_at (date), link (varchar 255)
Now you have good the background information, let us move one step further:
Model creation
You have to create migrations for your new models. Just open a terminal and generate them with the normal rails generators:
rails g model User first_name:string last_name:string email:string isfemale:boolean
rails g model Project title:string teaser:text description:text published_at:date, link:string
Do not forget to migrate your database:
rake db:migrate
Now you have generated your models and you can add some validations. In this scneario I add the "presence: true" validation to every model attribute.
Importer Structure
You have a mysql dump and want to import this dump into the new schema. I will now explain how you can do that through a Raketask.
You need a Importer class and a normal Raketask. For a better structure I will split up the Importer class into different modules. The structure of the whole importer looks like as follows:
 - /lib/tasks/project_name.rake: this file contains the Raketasks
 - /lib/tasks/importer/importer.rb: Importer class which includes the different sub-importer modules and all necessary extension files.
 - /lib/tasks/importer/users_importer.rb: sub-importer module which contains the users importer stuff.
 - /lib/tasks/importer/projects_importer.rb: sub-importer module which contains the projects importer code.
Subsequently I want explain each of this classes and modules. Let's start with the Raketask file
namespace :project_name do
 require Rails.root + "lib/tasks/importer"
 desc "Import old database, usage: rake project_name:import['old_database_name']"
 task :import, :oldDatabase, needs::environment do |t, args|
 args.with_defaults(oldDatabase: "import")
 oldDatabaseName = args.oldDatabse
 newDatabaseName = YAML::load("config/database.yml")))[Rails.env]["database"]
 importer = newDatabaseName, oldDatabaseName
This is the.rake-File and contains just one normal Raketask. This Raketask requires the name of the old database. For example you create a new database called "old_database" with phpmyadmin or a tool like that. After that you have to import the mysql dump from your old database in the currently new created one. The next step is to call the Raketask in your terminal: "rake project_name:import['old_database']. This will trigger the import. At this moment the import will fail, because you do not have neither the Importer class nor the instance method "execute" called at the end of the Raketask. So let's move further to the Importer class.
require File.dirname(__FILE__) + "/users_importer"
require File.dirname(__FILE__) + "/projects_importer"
class Importer
 # include sub-modules
 include UsersImporter
 include ProjectsImporter
 # initializer for a new importer
 def initialize new, old
 # feedback for the programmer
 puts "Importing from #{old} to {new}"
 _USER_ = new
 _USER_ = old
 # execute the import
 def execute
 # if you do not like to import data, if the new database
 # already contains data, just a security hint..
 if User.count > 0
 raise "Import aborted! There already are users in the database."
 if Project.count > 0
 ..and so on..
 # call sub-importer modules
 # later in the import process you have to switch beween
 # the old and the new database.
 # use new database (= switch to new database)
 def use_new_database
 ActiveRecord::Base.connection.execute("use #{_USER_}")
 # use old database (= switch to old database)
 def use_old_database
 ActiveRecord::Base.connection.execute("use #{_USER_}")
The importer.rb contains the Importer class with a normal initializer and an execute method. This method just calls all sub-module importer methods to completely start the import. At this moment it will not work, because the sub-modules do not exist yet. But in the end everthing will work together very good :-). Furthermore the Importer class has two helper methods to switch between the old and the new database.
Do not forget to include the different sub-modules in the Importer class, otherwise it will not work and you will get include errors and undefined methods.
For convenience you can write following mysql extensions and put them in the importer.rb File under the Importer class, but not in the Importer class.
# custom mysql row to facilite access
class Row
 def initialize fields, values
 _USER_ = fields
 _USER_ = values
 def get field
# Add get_row method to Mysql2::Result class
class Mysql2::Result
 def get_row index self.fields, self.to_a[index].to_a
Now let's start with the first import script:
module UsersImporter
 # import users
 def import_users
 puts "Importing users..."
 users = ActiveRecord::Base.connection.execute('
 SELECT pid, uid, firstname, lastname, mail, isfemale FROM Person
 for i in 0...users.count do
 row = users.get_row i
 user = User.where(first_name: row.get("firstname"),
 last_name: row.get("lastname"),
 email: row.get("mail"),
 isfemale: row.get("isfemale"))
 unless user
 user = row.get("firstname"),
 last_name: row.get("lastname"),
 email: row.get("mail"),
 isfemale: row.get("isfemale"))
 rescue Exception => e
 puts "Failed to save #{row.get("firstname")} #{row.get("lastname"): #{e.message}"
This sub-module contains the users importer. You can see that you have to use pure Mysql for the queries in the old database. That's because you do not have a model and cannot use the ActiveRecord ORM.
module ProjectsImporter
 # import projects
 def import_projects
 puts "Importing projects..."
 projects = ActiveRecord::Base.connection.execute('
 SELECT wid, headline, text_facts, text_long_facts, pub_date, hyperlink FROM work
 for i in 0...projects.count do
 row = projects.get_row i
 project = Project.where(title: row.get("headline"),
 teaser: row.get("text_facts"),
 published_at: row.get("pub_date"))
 unless project
 project = row.get("headline"),
 teaser: row.get("text_facts"),
 description: row.get("text_long_facts"),
 published_at: row.get("pub_date"),
 link: row.get("hyperlink"))
 rescue Exception => e
 puts "Failed to save #{row.get("title")} #{row.get("published_at"): #{e.message}"
The projects importer works exactly like the users importer. There is one method which handles the import.
Now everything should work and you are done. I know that my example import scripts are not really heavy to program, but I just wanted to explain how you could structure such an importer. If you have a database with a lot of joins and a tricky schema your import script will be much much more complicated. But with this importer-structure you just have to add a new module which handels the import part, call the method from the module in the Importer class and you are done.
You always should keep a very close eye on the topic "Testing". You should test your importer script before starting an import on your production system, that is very important! Otherwise you can destroy your production database and that never is funny ;-)
Feel free to comment on this blogpost, I will be happy about that! If you are interested in a more difficult importer script do not hestitate to ask me.

Southampton's historic dock gates saved from demolition
SOUTHAMPTON'S famous dock gates have been saved.
A Government preservation order has been placed on the imposing landmarks, just days before they could have been knocked down.
When plans by Associated British Ports (ABP), owners and operators of the city's docks, emerged last month to demolish the distinctive structures, there was a local outcry to save the long-standing landmark gates.
Following a recommendation by English Heritage to the Government, the entrances at Dock Gate 8 and Dock Gate 10 have now been safeguarded for future generations and are officially listed as Grade II buildings.
Heritage watchdog the City of Southampton Society was so concerned over the planned destruction it submitted an application straight away once details of the proposed scheme were made public.
Arthur Jeffery, the society's vice-chairman, said: "We are absolutely delighted at this news as the gates are an important part of the city's historic waterfront.
"These are art deco style gates and the society feared that they could have gone the same way as the former Ocean Terminal in the Eastern Docks back in 1982."
Southampton City Council also recommended the gates to be listed, describing them as "a rare and evocative survival of inter-war maritime port structures of clear special architectural and historical interest".
A Grade II listing means a structure is considered to be nationally important and imposes strict regulations and limitations on future work and repairs, which can be carried out on the structure.
Back in the 1950s when the docks were known as the "Gateway the World" because of the many ships departing to all corners of the globe, these were the two gates through which most people began their journeys.
During the Second World War the structures, especially Dock Gate 8, guarded the docksides, especially during the build-up to D-Day in June, 1944, when more than two million American soldiers left Southampton for the beaches of Normandy.
The same gate was the backdrop when hundreds of dispirited German prisoners of war trudged from the waterfront before being dispersed to various camps.
ABP had wanted permission to demolish the gates and was making preparations for the work to be done at the end of this month.
The port operator argued that the gates, which have stood since the development of the Western Docks in the 1930s, were obstacles standing in the way of progress and demolition would allow bigger loads to enter the port, ease traffic delays and provide extra security facilities.
An ABP spokesman said: "We understand that the Southampton Dock Gates have been listed as Grade II structures. "ABP is of course happy to respect the decision and will take the existing infrastructure into account when planning any future developments."

The Aperture Science Weighted Storage Cube, along with its Weighted Companion Cube variant, is the most common and basic testing element in Portal and Portal 2. It is used throughout the testing courses of the Aperture Science Enrichment Center.
- The Weighted Storage Cube is a device used for solving cube-and-button based puzzles in the various Test Chambers found throughout the Enrichment Center.
- In Portal and the Single Player campaign of Portal 2, Weighted Storage Cubes are to be placed on a Super Button to allow Test Subjects to advance.
- In the cooperative campaign of Portal 2, the Weighted Storage Cubes are to be placed on Cube Buttons.
- Weighted Storage Cubes appear either via an Aperture Science Vital Apparatus Vent or are already in a test chamber.
- It can be picked up by using the "use" key and can also be taken through portals.
- The Weighted Storage Cube can also be used as a makeshift weapon against an Aperture Science Sentry Turret by dropping it on the Sentry Gun from a Portal, or as a makeshift shield to block turret fire and energy pellets.
- Like most objects, the Weighted Storage Cube will disintegrate upon touching an Aperture Science Material Emancipation Grill.
- In Portal 2, the cubes have a circular blue light on each side, and when left on a button it changes to a yellow light. They are also notably smaller in size than in Portal.
- The Weighted Companion Cube in Portal 2 bears a resemblance to the standard Cubes, their only difference is that they have a heart on each face of the Cube and emit a pink light.
- A special type of Storage Cube, the Weighted Companion Cube appears in both Portal and Portal 2. It is identical to the regular Weighted Storage Cube in both games, except that it has a heart where the Aperture Science logo would be. At the end of the Test Chamber 17 in Portal, the player is forced to throw it into an Aperture Science Emergency Intelligence Incinerator. Narrative provided by GLaDOS and Doug Rattmann suggests that the Companion Cube is designed to test emotional stress by having subjects develop affection for it before being forced to destroy it.
- In Portal 2's second chapter Test Chamber 07, GLaDOS reveals that there are warehouses full of Weighted Companion Cubes shortly after disintegrating two of them. She also contradicts her statements from the first game, openly stating that they are sentient. As the Material Emancipation Grill for that chamber is not functioning, Chell can remove the companion cube from that chamber (earning the player the "Preservation of Mass" achievement/trophy), only to have GLaDOS destroy it herself shortly before reaching the elevator.
- It is unknown whether the Companion Cube can communicate openly in any way. Although generally the Cube actually talking seems to be a sign of madness, if the "Preservation of Mass" achievement is earned, GLaDOS claims the Cube was about to say "I love you," and in Portal 2, the Cube produces a chime, which foreshadows the Turret Opera.
- Twentieth century prototypes of the Storage Cubes were seen in the old condemned parts of the Aperture Science Innovators test chambers, where they also served a similar purpose for weighing down buttons. These cubes can react to the Mobility Gels, as well. It is unknown if the early cubes were simple crates with nothing inside, or if they were actually weighed down to help push down and hold in place the early Aperture Science Super Buttons. These cubes also appear to be made of wood, held together by staples. No analogue of the Companion Cubes appear.

Behind the scenes
- The Weighted Companion Cube was invented because playtesters often failed to realize that the puzzle required you to take the cube with you, so they made it unique and more noticeable, and had GLaDOS put a great deal of emphasis on it in her voiceover.
- A Weighted Companion Cube plush and fuzzies are available to purchase online at Valve online.
- A Companion Cube prop can be unlocked for Xbox Live avatars by completing the Portal 2 Single Player campaign.
- The teaser trailer version of GLaDOS' Incinerator Room features the burned Companion Cube.
- The Companion Cubes seem to replace Storage Cubes in the Aperture Investment videos.
- The Companion Cube from Portal is implied to have never been completely incinerated during the ending sequence of Portal 2. This is noted by the amount of burns marks it has sustained, also implied from statistics of the Portal Gun which can endure temperatures of up to 4000 kelvin, that subsequent Aperture products are also able to. In addition, the Companion Cube in Portal 2 sports a new design, but the cube in the ending sequence is the Portal design.
- In Portal 2, when held, the Companion Cube causes the game to play a type of tune or chime specific to it, much like how certain music plays during the activation or use of certain testing elements of functioning Aperture Science technology (eg. Aerial Faith Plate). The tune is a loop that foreshadows the upcoming Turret Opera at the end of the campaign.
- In the Xbox 360 game Fable III, a crate with a heart painted on each of its sides can be found in one of the game's dungeons, being worshipped by a creature called a Hobbe. On the table next to the cell in which the Hobbe is being kept, there is also a Cake.
- In Call of Duty: Modern Warfare 2 there is an unlockable title called "Companion Crate" on hearts background, most likely referring to Portal and Portal 2
Weighted Storage Ball, the model of which is shared with that of the simplified Personality Core.

Causes of Avalanches
Avalanches can be caused by many different things. Some of them are natural. For example, new snow or rain can cause accumulated snow suddenly to dislodge and cascade down the side of a mountain. Earthquakes and the natural movements of animals have also been known to cause avalanches.

The content of circuits and Arduino sketches can vary greatly. Before you get started, there is one simple process for uploading a sketch to an Arduino board that you can refer back to.
Follow these steps to upload your sketch:
 1. Connect your Arduino using the USB cable.
 The square end of the USB cable connects to your Arduino and the flat end connects to a USB port on your computer.
 2. Choose Tools→Board→Arduino Uno to find your board in the Arduino menu.
 You can also find all boards through this menu, such as the Arduino MEGA 2560 and Arduino Leonardo.
 3. Choose the correct serial port for your board.
 You find a list of all the available serial ports by choosing Tools→Serial Port→ comX or /dev/tty.usbmodemXXXXX. X marks a sequentially or randomly assigned number. In Windows, if you have just connected your Arduino, the COM port will normally be the highest number, such as com 3 or com 15.
 Many devices can be listed on the COM port list, and if you plug in multiple Arduinos, each one will be assigned a new number. On Mac OS X, the /dev/tty.usbmodem number will be randomly assigned and can vary in length, such as /dev/tty.usbmodem1421 or /dev/tty.usbmodem262471. Unless you have another Arduino connected, it should be the only one visible.
 4. Click the Upload button.
 This is the button that points to the right in the Arduino environment. You can also use the keyboard shortcut Ctrl+U for Windows or Cmd+U for Mac OS X.
Now that you know how to upload a sketch, you should be suitably hungry for some more Arduino sketches.

First Year Interest Groups (FIGs)
What is a FIG?
Belonging to a First-Year Interest Group (FIG) is a great way for first-time students to meet other students as well as develop strong relationships with upper-class students and many faculty members.
Students who are in a FIG take courses together each semester that fulfill some major requirements or some general education requirements to help ensure they are building a strong educational foundation. The FIG program is a year-long initiative that creates a strong community for first year students both in the classroom and in the residence halls.
FIG students live together in a residence hall with the upperclassmen mentors who work with the students.
Each FIG is based on an interest that the students share (i.e. adventure, art, business, theatre, etc.) and is led by students who have been at ASU for at least one year and can help students with any questions or concerns that arise in the first year of college.
2015-2016 FIG Groups:
The FIG Program is always changing and improving please check the FIG brochure for the most recent list of programs offered:

What does it mean to 'keep your powder dry'?
What does it mean to 'keep your powder dry'?
Image source: Getty Images.
'Keep your powder dry' is a saying that you may be familiar with. But have you ever wondered what it means or where it comes from? This colloquial expression from the 1800s once worked as an alternative to 'take care' or 'be ready'.
Plot your path towards financial freedom with our Hero's Journey tool!
Over time, the phrase has found its way into the financial world, where it now means to always be ready for opportunities.
Basic meaning
The Cambridge Dictionary says that 'keep your powder dry' means 'remain cautious and ready for a possible emergency'. This refers more to always being prepared so you can take action if necessary rather than a warning about danger. It's a suggestion to avoid missing out on a great opportunity because you didn't consider all possibilities.
Origin of the expression
English general and statesman Oliver Cromwell is credited with creating the expression. The story goes that Cromwell was talking to his army during his campaign in Ireland. He warned them about keeping their gunpowder dry as they were about to cross a river before a battle. So, as a mix of warning and inspiration, he told his soldiers to 'Trust in God and keep your powder dry'.
About two hundred years later, British Army officer William Blacker used the entire phrase in his poem Oliver's Advice and made it famous. Over the years, the second half of the sentence has become commonplace on its own. It was even used as a movie title for a 1945 American drama film starring Lana Turner.
Financial applications
The concept of dry powder has made it into the financial world in the past few decades. It is mostly used to mean 'hold cash or liquid securities' in case a big opportunity opens up. When a company has cash reserves, it becomes easier to invest in a sudden opportunity, buy stocks or participate in a now-or-never deal.
Could you be rewarded for your everyday spending?
Rewards credit cards include schemes that reward you simply for using your credit card. When you spend money on a rewards card you could earn loyalty points, in-store vouchers airmiles, and more. MyWalletHero makes it easy for you to find a card that matches your spending habits so you can get the most value from your rewards.
Investopedia refers to 'dry powder' as cash reserves kept on hand for potential acquisitions, purchase of assets or payment of obligations (like tax). Highly liquid securities are also cash-like. These include short-term investments, money market accounts and instruments that you can sell quickly for emergency funding.
While cash reserves are especially important for venture capitalists and corporate environments, they also have a role in personal finance.
Holding some of your personal net worth in cash means you will have money available for both opportunities and emergencies. A threeto six-month emergency fund is an example of this.
Examples of liquid assets
Thinking about keeping your own powder dry? There are different ways to keep money easily accessible. Keeping money in a savings account is the easiest way to have liquid assets available. While interest rates are low, you can still find a savings account that offers a decent return on your deposit.
Stocks and shares are also good examples of liquid assets. You can buy and sell in the stock market at any time and access the funds within a few days.
If you have a business, your accounts receivable (money your customers owe you) is also a liquid asset. Of course, how soon you have access to it depends on how quickly your customers pay you.

Reading, Desire, and the Eucharist in Early Modern Religious Poetry
The courtly love tradition had a great influence on the themes of religious poetry—just as an absent beloved could be longed for passionately, so too could a distant God be the subject of desire. But when authors began to perceive God as immanently available, did the nature and interpretation of devotional verse change? Ryan Netzley argues that early modern religious lyrics presented both desire and reading as free, loving activities, rather than as endless struggles or dramatic quests.
Reading, Desire, and the Eucharist analyzes the work of prominent early modern writers—including John Milton, Richard Crashaw, John Donne, and George Herbert—whose religious poetry presented parallels between sacramental desire and the act of understanding written texts. Netzley finds that by directing devotees to crave spiritual rather than worldly goods, these poets questioned ideas not only of what people should desire, but also how they should engage in the act of yearning. Challenging fundamental assumptions of literary criticism, Reading, Desire, and the Eucharist shows how poetry can encourage love for its own sake, rather than in the hopes of salvation.

Johan Svendsens lost or unfinished symphony. Elaborating sketches for performance
- Side: 33-73
- Publisert på Idunn: 2011-11-03
Johan Svendsen (1840–1911) was probably the most important contributor to a symphonic tradition in Norway in the second half of the 19th century. His works, including two notable symphonies, were performed regularly during his lifetime. Several sources have claimed that Svendsen worked on a third symphony, but it may seem that he was un-able to complete the work as his compositional activity waned in the 1880s. However, a famous anecdote would have it that his wife, in a fit of jealousy, burned the completed manuscript.
In 2007, conductor Bjarte Engeset identified sketches for a cyclic symphonic work by Svendsen. I have elaborated and arranged parts of the material for a celebratory concert marking the centenary of Svendsens death.
A performable version, so to speak, of the sketches, to my mind throws new light not only on an unfinished or lost symphony but may also be a valuable contribution to understanding Svendsens artistic development, as this material demonstrates a more dramatic musical language than most of his earlier works.Keywords: Johan Svendsen, Third Symphony, reconstruction


MPGe explained
EPA electric label
Unlike the NEDC (New European Driving Cycle), EPA's fuel economy data is considered reliable and feasible in the real world. Unfortunately EPA uses MPGe for plug-in cars instead of kWh per 100 miles, or Wh per mile.
Since in Europe we are accustomed to use L/100 km in gas cars, let's use kWh/100 km for the conversion.
We need to convert gallon to kWh and miles to kilometers.
EPA considers that one gallon of gas contains 33,7 kWh worth of energy. For the miles to kilometers conversion we can use the online calculator in the links at the bottom.
Taking the 2016 BMW i3 BEV as an example we have:
124 MPGe combined (city and highway driving).
This means that with 33,7 kWh of electricity we can drive for 199,56 km.
To get kWh per 100 km:
33,7 kWh / 199,56 km x 100 km = 16,89 kWh/100 km
Using the Nissan Leaf 30 kWh as example:
33,7 kWh / 180,24 km x 100 km = 18,7 kWh/100 km
If you want to buy an electric car and don't know what range in one charge can you expect, it's a good idea to check the fuel economy data in the links below.
