1. Begin with a slightly melted ice cube in your mouth. Kiss your guy and pass it back and forth. As it gets smaller and smaller, hide it in different places so he has to try to find it with his tongue.
2. Use the ice cube to trace a chilly path along his naked body and then follow it with your tongue. The temp change will heighten his pleasure, while the anticipation of watching where your lips go will send him over the edge.
3. Put the ice in your man's hand and guide it so that he draws circles around the outside of your breasts, slowly working his way toward your nipples.
4. While giving your guy oral, alternate putting your lips over his penis and lightly rubbing his shaft with the ice cube. The combination of your warm mouth and chilly temperature will make his jaw drop.
5. Ask him to touch you with it over your thin-skinned spots: wrists, inner elbow, behind your knees. Stimulating those sensitive areas feels so sensual.
6. When your guy is going down on you, have him alternate between lightly touching your clitoris with the ice and using his mouth and tongue. If you're extra-sensitive down there, try it with your underwear on.
7. Place the ice cube between your breasts and run it back and forth so that your skin feels cool and wet, then guide your man's penis between them for a hands-free massage.
8. Have him lightly run the ice cube along the soles and the perimeter of your feet. Believe it or not, the area of the brain that processes touch down there is nearby the zone that registers sensations to your genitals, speeding up your arousal.
9. Give your guy a sexy scalp rub with one hand and use the other to trail the ice along his hairline and temples, all the way down to the base of his neck.
10. Post-sex, slowly move the ice cube across your guy's back for a frisky cooldown, then ask him to return the favor.

UK researchers develop ultrasonic needle
A University of Glasgow-led project, which is developing this new type of surgical needle, is one of 15 engineering projects to share in 12.2 million pounds of funding from the Engineering and Physical Sciences Research Council (EPSRC).
Margaret Lucas, Professor of Ultrasonics at the University's School of Engineering, and her partner researchers at the Universities of Dundee and Edinburgh have received 982,000 pounds to support three years of work to develop a needle which vibrates at ultrasonic frequencies.
Previous ultrasonic cutting technology developed by Prof Lucas and her team is capable of removing the shell of an egg without damaging the membrane below.
The technology would allow doctors to penetrate bone with needles with much less force than is currently required, improving the effectiveness of biopsies and allowing a more effective delivery of drugs to parts of the body obscured by bone.
Ultrasonic needles could also make it easier for doctors to penetrate areas of hard tissue without affecting the surrounding soft tissue.
Previous research carried out by Professor Lucas has led to the development of ultrasonic cutting tools precise enough to remove sections from the shell of an egg without breaking the membrane underneath.
Professor Lucas said: "We've been working for several years to explore the applications of ultrasonic vibrations to allow surgeons to cut through bone more quickly and easily, and we're excited about the potential of applying

ANALYSIS OF NINE YEARS OF RAILROAD PERSONNEL CASUALTY DATA
This report presents an analysis of railroad personnel casualty data for the years 1966 through 1974. The analyses examined the trends of injuries, days disabled, fatalities, and the effect of changes in man hours of employment on these trends. Accident cause categories were ranked year by year based on an index which took account of both the frequency or number of casualties in each cause category and the severity of the casualties, as measured by the median days disabled for each cause category. Also, the frequency-severity index was used to rank job classifications for each year.

Constraint Propagation Algorithms for Temporal Reasoning
Marc Vilain, Henry Kautz
This paper considers computational aspects of several temporal representation languages. It investigates an interval-based representation, and a point-based one. Computing the consequences of temporal assertions is shown to be computationally intractable in the interval-based representation, but not in the point-based one. However, a fragment of the interval language can be expressed using the point language and benefits from the tractability of the latter.

The objective of the present study was to evaluate the composition of B horizon equilibrium soil solutions from selected Maine forest soils. The B horizon was chosen for evaluation because it (1) best expressed the weathering processes active in the soil, (2) occupied the greatest volume of the solum, (3) had the most complex chemistry of the major horizons, and (4) provided the major corridor in forested ecosystems for subsurface flow and chemical alteration of ground waters.

SQL Server: Identity Property Part-1
Identity property is one of the most frequently used properties to generate auto increment value. I've seen sometime developer get confused with it. So this blog series will help developers to know everything about Identity property.
Syntax: IDENTITY [(seed, increment)]
You must specify both the seed and increment or neither. By default the value of seed and increment is (1, 1). Identity column must be of data type int, bigint, smallint, tinyint, or decimal or numeric with a scale of 0 and constrained to be not null.
The identity property on a column guarantees the following:
- Each new value is generated based on the current seed & increment value.
- Each new value for a particular transaction is different from other concurrent transactions on the table.
- Identity property does not guarantee uniqueness of column value.
- A transaction inserting multiple rows is not guaranteed to get consecutive values for the rows because other concurrent inserts might occur on the table. To get consecutive values the transaction should use an exclusive lock on the table or it should use the SERIALIZABLE isolation level.
- SQL Server might cache identity values for performance reasons and some of the assigned values can be lost during a database failure or server restart. This can result in gaps in the identity value upon insert. If gaps are not acceptable then the application should use a sequence generator with the NOCACHE option or use their own mechanism to generate key values.
- The identity values are not reused by the engine, If a particular insert statement fails or if the insert statement is rolled back then the consumed identity values are lost and will not be generated again.

The PING Project
This map shows data reported by users of the mPING app during Friday's blizzard in the Northeast.
This map shows data reported by users of the mPING app during Friday's blizzard in the Northeast. The PING Project
If you love to talk about the weather — or want to help collect information about it — a new smartphone app may be for you.
The National Oceanic and Atmospheric Administration and the University of Oklahoma are giving regular folks an opportunity to fiddle with weather reporting. Using crowdsourcing, the mobile Precipitation Identification Near the Ground app collects geographic, winter precipitation data from users. The mPING app also links to a map showing weather reports sent in by locals.
The data collected by the app will help weather officials program radar to determine exactly what's falling near you. For example, is it hail or mixed rain?
The free app is currently available for the iOS and Android operating systems.
Screengrab of mPING
The National Oceanic and Atmospheric Administration and the University of Oklahoma's new mPING app helps forecasters capture a better description of falling precipitation.

Users anonymously update reports by selecting a variation of winter weather between "none" and "graupel/snow grains,"* their GPS location is noted, and information is sent in to NOAA. (It can also be done through NOAA's website, but an extra step of figuring out your longitude and latitude has to be completed.)
"The purpose of PING is to give us ground observations of precipitation types that are not well observed from automatic systems," Kim Elmore, a science researcher working on the project, told All Things Considered. He says the gathered information will be used to build algorithms for newly upgraded radars.
The data can also help officials and the public prepare for severe weather, he says.

The PING project captures data from locals on its app or website. Users are able to choose from different types of precipitation.

"If we can better marshal our resources for dealing with it, then it may not cost quite so much and people may not be in quite such jeopardy," Elmore says. Throwing salt, buying sand, fixing wires and removing fallen trees can be constant expenses, he adds.
mPING is just the latest weather app to use crowdsourcing. Others include Weddar, which asks users to add a colorful description of the weather; and Metwit, a hyperlocal app that lets you pin photos to your weather reporting.
The app had a "soft launch" in December, but it has already become popular.
Elmore estimates about 20,000 people have downloaded the app and nearly 60,000 reports have been submitted. The project itself has been around since 2006, using different methods like cold-calling to verify falling precipitation.
Much of its popularity may come from the high level of interest in weather and science, Elmore says. The "real hook" is the data readily available for people to view on their phones.
So this app may not break the ice for your weather forecasting career, but it may someday help your local weatherman have an accurate picture of what's going on outside your window.
* In case you're wondering, NOAA's National Severe Storms Laboratory says graupel (aka soft hail or snow pellets) are "soft small pellets of ice created when supercooled water droplets coat a snowflake."

How can I switch between combs?
Be certain the clipper is in the OFF position.
 1. Select the comb attachment depending on the desired hair length. In the attached file you can find the settings and remaining hair lengths. The remaining hair length is also indicated on each comb.
 2. Slide the selected comb into the guiding grooves on both sides of the Clipper swivel head and push until you hear it click' into place (fig. 1). Make sure the comb attachment locks properly into position.
 3. Turn the Hair Length Setting Adjustment Ring to set the comb to the desired setting (fig. 2). Do not turn the length setting adjustment ring beyond the highest hair length setting.
 4. The arrowhead on the Clipper indicates which setting has been selected.
When you are clipping for the first time, start at the maximum clipping length setting (#5) of the regular comb to familiarize yourself with
the appliance and prevent accidentally trimming hairs too short. As you become familiar with the settings, adjust the Hair Length Selector to desired trimming length.

A_SmokeTrailer is an action that is used to spawn a trail of Objects of a type determined by Var1 when called repeatedly. In Doom Legacy, this action was originally used to spawn smoke trails for rockets and Lost Souls; the action itself is based on the action A_Tracer from Doom, used for the Revenant's homing missiles, which spawned a smoke trail and followed the tracer. A_SmokeTrailer in comparison reuses only the smoke-spawning code from A_Tracer, hence the name of the action. In SRB2, this is used to spawn smoke trails behind the Snailer's missile and the Sea Egg's torpedo.
The position the Objects are spawned at relative to the actor depends on the speed and direction of the actor's current movement, set up so it will trail behind opposite to the actor's movement direction, and the Objects will only be spawned every 4 tics. The spawned Objects will then rise slowly in the air at a speed of 1 fracunit/tic, and their initial state's duration is randomly reduced by 0-2 tics.

Definition - What does Virtual Routing and Forwarding (VRF) mean?
Virtual routing and forwarding (VRF) is a technology within IP based routers that enables them to create and operate multiple instances of a routing table simultaneously. VRF enables a router to create multiple instances of router within it, each of which operates separately and has its distinct and overlapping set of IP addresses.
Techopedia explains Virtual Routing and Forwarding (VRF)
VRF is primarily implemented for better use of router and segregate network traffic. VRF works like a typical router with its unique routing table, table entries and routing protocols, and it works independently of the core router and other VRF created instances. VRF is similar to virtual routers but the latter uses only one routing table whereas VRF has multiple routing tables. VRF is also used to create VPN tunnels that are solely dedicated to a single client or network.
VRF is also referred to as a routing table that has multiple instances on a VPN power edge (PE) router.

Nickname: Fighting Tigers
The Nickname: "Fighting Tigers"
Way back in the fall of 1896, coach A.W. Jeardeau's LSU football team posted a perfect 6-0-0 record, and it was in that pigskin campaign that LSU first adopted its nickname, Tigers.
'Tigers' seemed a logical choice since most collegiate teams in that year bore the names of ferocious animals, but the underlying reason why LSU chose 'Tigers' dates back to the Civil War.
According to Arthur W. Bergeron, Jr., PhD. and the "Guide to Louisiana Confederate Military Units, _PHONE_" (LSU Press, 1989), the name Louisiana Tigers evolved from a volunteer company nicknamed the Tiger Rifles, which was organized in New Orleans. This company became a part of a battalion commanded by Major Chatham Roberdeau Wheat and was the only company of that battalion to wear the colorful Zouave uniform. In time, Wheat's entire battalion was called the Tigers.
That nickname in time was applied to all of the Louisiana troops of Robert E. Lee's Army of Northern Virginia. The tiger symbol came from the famous Washington Artillery of New Orleans. A militia unit that traces its history back to the 1830s, the Washington Artillery had a logo that featured a snarling tiger's head. These two units first gained fame at the Battle of First Manassas on July 21, 1861. Major David French Boyd, first president of LSU after the war, had fought with the Louisiana troops in Virginia and knew the reputation of both the Tiger Rifles and Washington Artillery.
Thus when LSU football teams entered the gridiron battlefields in their fourth year of intercollegiate competition, they tagged themselves as the 'Tigers'.
It was the 1955 LSU 'fourth-quarter ball club' that helped the moniker 'Tigers' grow into the nickname, 'Fighting Tigers'.
Thanks to Arthur W. Bergeron, Jr., PhD., a historian at the Pamplin Historical Park, for contributing to the above information.
Colors: Purple and Gold
There is some discrepancy in the origin of Royal Purple and Old Gold as LSU's official colors.
It is believed that those colors were worn for the first time by an LSU team in the spring of 1893 when the LSU baseball squad beat Tulane in the first intercollegiate contest played in any sport by Louisiana State University. Team captain E.B. Young reportedly hand-picked those colors for the LSU squad.
Later that year, the first football game was played. On November 25, 1893, football coach/chemistry professor Dr. Charles Coates and some of his players went into town to purchase ribbon to adorn their gray jerseys as they prepared to play the first LSU gridiron game.
Stores were stocking ribbons in the colors of Mardi Gras -- purple, gold and green. -- for the coming Carnival season. However, none of the green had yet arrived at Reymond's Store at the corner of Third and Main streets. Coates and quarterback Ruffin Pleasant bought up all of the purple and gold stock and made it into rosettes and badges.

LSU Alma Mater
Where stately oaks and broad magnolias
shade inspiring halls,
There stands our dear Old Alma Mater
who to us recalls
Fond memories that waken in our hearts
a tender glow,
And make us happy for the love
that we have learned to know.
All hail to thee our Alma Mater,

May greater glory, love unending
be forever thine.
Our worth in life will be thy worth
we pray to keep it true,
And may thy spirit live in us, forever L-S-U.
"Fight For LSU"
Like Knights of old, Let's fight to hold
The glory of the Purple Gold.
Let's carry through, Let's die or do
To win the game for dear old LSU.
Keep trying for that high score;

"Hey Fighting Tiger"
(Adapted from the original composition 'Hey, Look Me Over' from the Broadway production 'Wildcat'.)
Hey, Fightin' Tigers, Fight all the way
Play, Fightin' Tigers, win the game today.
You've got the know how,
you're doing fine,
Hang on to the ball as you hit the wall
And smash right through the line
You've got to go for a touchdown
Run up the score.
Make Mike the Tiger stand right up and roar.
Give it all of your might as you fight tonight
and keep the goal in view.
Victory for L-S-U!

Long ago, way down in the jungle
Someone got an inspiration for a tune,
And that jingle brought from the jungle
Became famous mighty soon.
Thrills and chills it sends thru you!
Hot! so hot, it burns you too!
Tho' it's just the growl of the tiger
It was written in a syncopated way,
More and more they howl for the 'Tiger'
Ev'ry where you go today
Where's that Tiger! Where's that Tiger!
Where's that Tiger! Where's that Tiger!
Hold that Tiger! Hold that Tiger!
Hold that Tiger!
"Touchdown for LSU" (Pregame)
Tigers! Tigers! They've come to town,
They fight! They fight! Call a first down,
Just look them over, and how they can go,
Smashing the line with runs and passes
high and low.
Touchdown! Touchdown! It's Tigers' score.
Give them hell and a little bit more.
Come on you Tigers, Fight them, you Tigers,
Touchdown for LSU.
Rah! U. Rah!

The Lab is where the New European Bauhaus is implemented in concrete and tangible projects. It is about what we can achieve when we work together in a spirit of openness and trust. It focuses on connecting people, learning from each other and tapping into everyone's experience.
NEB Lab projects manifest the New European Bauhaus into concrete actions with two missions:
- to create enabling conditions for the green transition, such as new tools, frameworks, policy recommendations, etc.
- to trigger tangible transformation on the ground
What does the NEB Lab do?
The NEB Lab is a project-based structure where teams self-organise to achieve tangible change in a specific place or context.
The New European Bauhaus Community and EU institutions autonomously develop projects proposals for the NEB Lab. Proposals become NEB Lab projects following a process that ensures a clear purpose, transparency towards the community, and well-defined beneficiaries.
The NEB Lab:
- Ensures coherence across projects and alignment with the New European Bauhaus principles.
- Supports project development by challenging proposals, connecting projects with the community and institutions for additional support, and bridging local action with the European and international dimension.
- Offers projects space on a dedicated online platform, mentoring and communication support.
The NEB Lab does not provide funding for projects, however project teams can consider support and financing options, e.g. support in kind, EU, national, regional or local public funding, sponsorship.
What are the key characteristics of NEB Lab projects?
NEB Lab projects are developed autonomously by a team of project coordinators and may receive support from several entities beyond the official New European Bauhaus Community. They count on independent experts and are expected to deliver change on the ground.
NEB Lab projects:
- Create or replicate beautiful, sustainable, inclusive places, products or experiences or enable initiatives to achieve that.
- Provide results that are practical and replicable.
- Are change processes that benefit communities and ecosystems.
- Are based on international and cross-sectoral partnerships.
- Inform the policy-making processes with their outputs, outcomes, and learnings.
- Offer open-source learning opportunities for Community members.
- Use participatory design methods and tools and draw on cross-disciplinary competences.
What is the relationship between the NEB Lab and the New European Bauhaus Community?
The New European Bauhaus community includes:
- the initiative's official partners
- the members of the High-Level Round Table
- the national contact points
- the New European Bauhaus prize winners and finalists
- the beneficiaries of New European Bauhaus calls
- the initiative's friends
- members of the European Commission
The Community is broader than the NEB Lab, but there is a link between the two.
Non-profit organisations can join the Community by becoming New European Bauhaus partners. Official partners undergo a screening process and are the only entities that can jointly propose projects for the NEB Lab. The New European Bauhaus team supports the maturing of emerging projects and validates the ones ready to become part of the NEB Lab.
For-profit organisations, companies, and public or political entities, such as regions, cities and villages, can also join the Community by becoming friends of the initiative. Friends of the New European Bauhaus can recommend NEB Lab activities to partners and support them in several ways, for example by implementing a projects in a region.

Experimental Studies of Turbulent Intensity around a Tidal Turbine Support Structure
AbstractTidal stream energy is a low-carbon energy source. Tidal stream turbines operate in a turbulent environment, and the effect of the structure between the turbine and seabed on this environment is not fully understood. An experimental study using 1:72 scale models based on a commercial turbine design was carried out to study the support structure influence on turbulent intensity around the turbine blades. The study was conducted using the wave-current tank at the Laboratory of Maritime Engineering (LABIMA), University of Florence. A realistic flow environment (ambient turbulent intensity = 11%) was established. Turbulent intensity was measured upstream and downstream of a turbine mounted on two different support structures (one resembling a commercial design, the other the same with an additional vertical element), in order to quantify any variation in turbulence and performance between the support structures. Turbine drive power was used to calculate power generation. Acoustic Doppler velocimetry (ADV) was used to record and calculate upstream and downstream turbulent intensity. In otherwise identical conditions, performance variation of only 4% was observed between two support structures. Turbulent intensity at 1, 3 and 5 blade diameters, both upstream and downstream, showed variation up to 21% between the two cases. The additional turbulent structures generated by the additional element of the second support structure appears to cause this effect, and the upstream propagation of turbulent intensity is believed to be permitted by surface waves. This result is significant for the prediction of turbine array performance. View Full-Text

DuPont and ADM launch bioplastic pilot plant
Article by Amanda Doyle
DUPONT and ADM have announced the opening of a pilot plant in that will be the world's first production facility for bio-based furan dicarboxylic methyl ester (FDME), which can be used to make a lightweight plastic.
The two companies developed a method for producing the long sought-after molecule FDME from fructose derived from corn starch in 2016. They have now moved to the pilot phase with the opening of a pilot plant in Illinois, US, which is expected to produce 60 t/y of FDME.
The DuPont and ADM facility. Credit: DuPont
FDME is a molecule that can be used to create chemicals and materials, including plastic. One of the first FDME-based molecules under development is polytrimethylene furandicarboxylate (PTF), a polymer that can be used to make more sustainable plastic bottles. PTF has a gas barrier that is 10-15 times higher than the commonly-used plastic polyethylene terephthalate (PET). This increases the shelf life of the product and reduces the amount of plastic needed to keep the CO2 in the drinks. PTF is produced using a more environmentally friendly method compared to PET, which is usually derived from petrochemicals.
"We're confident FDME is both the more sustainable option and the better-for-business option," said Michael Saltzberg, global business director for biomaterials at DuPont Industrial Biosciences. "This molecule, and its numerous applications, will be high-performing, cost-effective and better for the environment."

This spin-orbit induced polaron state has localization length inversely proportional to the Rashba coupling gamma and it dominates a wide region of the gamma-lambda phase diagram, where lambda is the electron-phonon interaction.

Acids and Alkalis
The process of making a
solid come from a solution is
called precipitation. The solid itself is called a precipitate.
An insoluble salt (one
that doesn't dissolve)
can be made by reacting the appropriate soluble salt
with an acid or alkali or another salt.
For examples of precipitation, see tests for ions including
precipitation using the alkali sodium hydroxide
the barium chloride test for sulfate ions
and the silver nitrate test for bromide, chloride and iodide ions.
Precipitation reactions can be used to remove ions from water.
Sodium carbonate can be used to precipitate calcium carbonate.
This is a way of making hard water into soft water.
+ sodium carbonate calcium carbonate +
CaCl2(aq) + Na2CO3(aq) CaCO3(s) + 2NaCl(aq)
The ionic equation is Ca2+(aq) + CO32-(aq) CaCO3(s)
A precipitate can be separated from the solution by filtration.
The precipitate can then be left somewhere warm to dry.

What is a Reverse NDR Attack
The non-delivery report (NDR) is generated when an email message is not able to be sent to the next hop.
Spammers can use NDR as a method to generate spam towards victims by using the victim's email address as the sender. This is called a reverse NDR Attack.
Consider the following scenario:
 - Bob (the victim), has an email address
 - You run an email server that accepts messages for In addition, it accepts messages for valid as well as invalid users.
 - Jim (the attacker), wants to send a spam message to Bob. However, instead of sending it directly to Bob, he sends it through your email server. He does this to prevent his IP address from getting black listed.
 - Jim's composes an email with the following values for Sender and Recipient:
Since does not exist, your email server will generate an NDR. However, that NDR will get sent to Bob instead of Jim, because Jim forged the sender to be Bob instead of Jim.
Refer to the diagram below for more information:
Preventing such attacks in Xeams
There are two features in Xeams that will help against a reverse NDR attack.
 - Configure Xeams to reject invalid users. This is done by specifying a valid list of users or integrating with Active Directory.
 - Configure how NDRs are generated.
 Configuring NDRs
 After logging in as admin, go to Smtp Server Configuration and select the Advanced Tab. Following bullets describe two important configuration parameters.
 Include Original:
 This option configures whether to attach the original email message in the NDR. By default, this option is disabled. It is highly recommend to leave this option disabled to prevent spammed messages.
 Generate NDRs only for outbound emails:
 This option only allows NDRs to be generated for outbound emails. This prevents the reverse NDR attack where someone uses your email server to bounce back spam messages.

What do liberals and conservatives look for in a date?
September 10, 2013 in Other Sciences / Social Sciences
For their study, titled "The Dating Preferences of Liberals and Conservatives," the research team randomly sampled 2,944 profiles from a popular Internet, and examined the dating preference of users who identified as either liberal of conservative. The data allowed them to compare the way each dater described themselves on a number of dimensions, including race and ethnicity, religion, and the desire to have children, to the characteristics of their ideal date. Overall, regardless of ideology, daters want a partner that shares their characteristics.
Klofstad says that the to seek out partners that are like us could contribute to the increasing political divide between liberals and conservatives. "Parents pass their on to their children. So, if we are more easily able to find someone like ourselves by'shopping' for a partner online, Internet dating could hasten this process of. Of course, this process would occur over, not overnight."
Other findings:
Few individuals were willing to express a definitive political preference. The majority of online daters, 57 percent, reported that their politics are "middle of the road" rather than liberal or conservative. When asked to describe their body type, a larger proportion of daters voluntarily described themselves either "heavy set," having "a few extra pounds" or "stocky" than listed "politics" as one of their interests.
Conservative daters are more likely to be males and are less likely to belong to a racial or ethnic minority group. Liberals are younger, less likely to have been married, and less likely to have children. While liberal daters are better-educated than conservatives, this does not translate into any detectable income disparities between the two groups.
By and large, liberals and conservatives do not differ in their tendencies to seek out a partner that shares their characteristics. There are some notable exceptions, however. Overall, conservatives appear to be somewhat less accepting of dissimilarity. For example, conservatives are more likely than liberals to desire a date who shares their current relationship status, and conservative males are more likely than liberal males to want to date a female of their own race.

Narrated By: Michael Morpurgo,
Duration: 6 hours and 48 minutes
What to expect
Written by Hugh Cunningham and presented by award-winning children's author Michael Morpurgo, this genuinely ground-breaking history of British childhood teaches us about the key elements that have shaped children's lives. The Invention of Childhood explores how gender, geography and ethnicity has impacted the development of children throughout the ages. Beginning from the year 1000, Cunningham studies the many important events in history for our children, ranging from Britain's earliest child-care guru in the Middle Ages to the first ever Foundling Hospital in the 18th Century. This hugely enjoyable piece of teaching that delves into the idea of how childhood has been constantly reinvented through the centuries, and why the role of children in society continues to obsess us today.
Fascinating and thought-provoking, it will appeal to parents, grandparents and anyone who has ever been a child themselves.

I have a question regarding multiple sums. And my second index depends on the first index. Here it is:
$$ \sum_{d=1}^{P}e^{-d}\sum_{\substack{1\leq k_{1}\leq Q \\ 1\leq k_{2}\leq Q \\... \\...\\1\leq k_{d}\leq Q}}e^{-(k_{1}+...+k_{d})} $$
I could not write this sum in mathematica. The problem is that my second sum is a multiple sum and I do not know how to sum $d$ times. How can I do it?

Let's concentrate on the inner multiple sum. First note that we know d because it is given from the outer sum. If we want to write the expression $$-\exp\left[k_1+k_2+\ldots+k_d\right]$$ in Mathematica we could do this very easy. First we create the list {k[1],k[2],...,k[d]} and remember, that this is internally nothing more than List[k[1],k[2],...,k[d]]. If we would now replace the List head with Plus, then it is exactly what we want. For this we can use Apply which is written @@ in infix notation. That leaves how to create the {k[1],k[2],...,k[d]} list. Here we can use Table or Array or we think of it as _mapping the function k over the list {1,2,...,d}. This can be written as
k /@ Range[d]
for a known d. All together this gives
Exp[-Plus @@ k /@ Range[d]]
Now we need to build a multiple Sum, summing over d different k. Again, this can be done in several ways. One way is to create a function which gets as arguments the indices for a Sum
f = Function[Sum[1, ##]]
I only use 1 in the sum for the sake of simplicity. You may ask now, what this ## is: it's the sequence of all arguments given to f. So lets try it:
In[63]:= {Sum[1, {3}], f[{3}]}
Out[63]= {3, 3}
In[62]:= {Sum[1, {3}, {5}], f[{3}, {5}]}
Out[62]= {15, 15}
Seems to work. The only think which is left now, is to create the ranges {k[i],1,q} where i is always a concrete number. Here we can use again the trick with Range and for a known d this gives a list of ranges:
{k[#], 1, q} & /@ Range[d]
(* For d = 3 for instance
Out[64]= {{k[1], 1, q}, {k[2], 1, q}, {k[3], 1, q}}
The last thing is to think about, that our Sum function needs a Sequence of arguments and the above is a List. But we already solved the problem of replacing the List with something different by using @@. This gives all together:
Sum[Exp[-Plus @@ k /@ Range[d]], ##] & @@ ({k[#], 1, q} & /@ Range[d])
Don't be afraid of the expression, because now you know every single piece of it and you know what every piece does. You could try it by for instance
With[{d = 4},
and get $$\frac{e^{-4 q} \left(e^q-1\right)^4}{(e-1)^4}$$ or you use this to plant it directly into your outer sum
mysum[p_Integer] :=
 Range[d]), {d, 1, p}]
I put it into a function mysum, because p needs to be a number to make all the Ranges work. Now you should check mysum[2]
$$\frac{e^{-2 q-2} \left(e^q-1\right)^2}{(e-1)^2}+\frac{e^{-q-1} \left(e^q-1\right)}{e-1}$$

I do not understand why mathematica doesnt give the closed expression for mysum. because it seems that mysum[n] gives $x+x^2+x^3+...+x^n$ where $x$ is mysum[1] – neticin May 3 '12 at 16:15

I'm not sure there's a way to do this symbolically, but you can do the following:
multipleSum[P_] :=
 Sum[Exp[-d] Sum[
 Exp[-Plus @@ Table[Symbol["k" <> ToString[i]], {i, 1, d}]],
 Sequence @@
 Table[{Symbol["k" <> ToString[i]], 1, Q}, {i, 1, d}]]], {d, 1,
For example:
In[87]:= multipleSum[3]
Out[87]= (E^(-1 - Q) (-1 + E^Q))/(-1 + E) + (
 E^(-2 - 2 Q) (-1 + E^Q)^2)/(-1 + E)^2 + (
 E^(-3 - 3 Q) (-1 + E^Q)^3)/(-1 + E)^3
I think this is correct.

POWER UP - Female Pop Art
Rediscovering outstanding women Pop artists, POWER UP fulfills Dorothy Iannone's combative promise after fifty years. The show aims at the reinterpretation of an art movement that until today has primarily been associated with male protagonists. Plastic, loud colors, reduced forms, and graphic contours – the nine women artists' works on display resemble those of their male colleagues in many respects. Whereas their works appeal to the taste of the masses, these artists, as pioneers of Feminism, have remained belligerent and critical. They reveal the consumer culture's superficiality, exposing the commodity myth as an empty shell like Christa Dichgans, ironically transforming everyday objects to oversized kitsch objects like Jann Haworth, or exploring mass media clichés and superstar constructions like Rosalyn Drexler. Like Sister Corita, a committed peace activist, they took a clear stand on the sixties' social and political events such as the Vietnam
The exhibition pursues its political perspective in those instances where the era's current notions of what a woman is are revised by different views: Kiki Kogelnik and Marisol describe the corset in which the representation of women by themselves and by others is caught, while Evelyne Axell or Dorothy Iannone provocatively display the nude body, love, and sexuality, and, like Niki de Saint Phalle, attract the viewer's attention with sophisticated modes of self-presentation.

Background: After a patient death, experienced physicians have reported feelings of sadness, guilt, and self-doubt. Residents and interns experience a strong emotional impact to these deaths as well, and previous studies have shown that they only feel adequately supported 50% of the time. Residents feel more supported by their attendings and are better able to emotionally cope if debriefs occur after adverse events or deaths. There are few studies on how frequently hospitalists hold debriefs after patient deaths and how best to conduct such discussions.
Purpose: The purpose of the study is to understand current practices in coping with patient deaths and to create a debrief tool to guide residents and hospitalists in conducting debriefs after a patient mortality or adverse event.
Description: The study was conducted at a large urban academic medical center. An initial anonymous survey was administered to Internal Medicine residents and hospitalists to understand current debrief practices. There were 13 hospitalist respondents and 31 resident respondents. The survey found that debriefs do not happen consistently, with only 31% of hospitalists reporting that they always debrief after a patient death or adverse event and 0% of residents reporting that their attending always leads debriefs. Although 77% of hospitalist respondents reported recognizing when trainees are having difficulty coping with a patient death or adverse event, only 55% of residents agreed that their attendings recognized that they were having difficulty coping. Furthermore, 65% of resident respondents reported that they were not aware of mental and emotional health resources and 69% of hospitalists reported that they have never provided such resources. Survey data also showed that 100% of the hospitalists had not received training on how to conduct debriefs, but 100% would want a tool to help them debrief.A debrief tool was created based on the need indicated from the survey (figure 1). Specific elements were selected from best practices when discussing difficult events and from a survey question related to physician perception of the purpose of debriefs. Further input was taken from focus groups of residents and hospitalists. Using the mnemonic SEEK, the tool emphasizes the following 4 components: Setting a stage, creating Expectations and a blame-free environment, discussing Emotions and providing additional Knowledge and resources. This tool also includes sample questions to guide the discussion when leading a debrief and resources for emotional and mental care. Laminated cards with the tool were published and made available online. Training sessions were conducted with both residents and hospitalists, and they were guided through elements of a debrief, sample questions to facilitate discussion, and how to use the tool. At the end of the training session, hospitalists and residents applied their newly learned skills to challenging clinical scenarios.
Conclusions: The development and implementation of a tool helped to establish an easily adopted method to facilitate debriefs. Follow-up comments from attendings and residents have shown that debriefs are occurring more frequently after adverse events and deaths, and that they have been helpful and very much appreciated by the residents. Further evaluations and results will need to be collected. Additionally, applying the tool to specialty services, in ICUs, and continuing to train additional residents and hospitalists will broaden the practice of debriefs.

The Learning Algorithms of Fuzzy Neural Network
|Keywords||Fuzzy Mathematics Artificial Neural Network Fuzzy Neural Network Self Organizing Algorithm Genetic Algorithm|
Artificial Neural Network (ANN) is a nonnumeric algorithm based on the imitation of the structure of human brain. The hybridization of Fuzzy Mathematics (FM) and Artificial Neural Network is Fuzzy Neural Network (FNN). As a new technology in the field of artificial intelligence, FNN is an important method for information extraction, and it has a very large scale of application. In this paper, in according to a lot of new achievements about Fuzzy Mathematics and ANN, we use Self Organizing Algorithm and Genetic Algorithm (GA) as the learning methods of FNN, hope to explore new way of information extraction from complicated data. The main research work includes:In section one, we present the theory of Fuzzy Mathematics and its applications.In section two, we mainly discuss the basic algorithm of ANN. In the past several decades, ANN has been applied in many fields extensively, and lots of different algorithms for ANN are created. In this paper, we will adopt the fundamental frame of BP ANN to construct the network system.In section three, by the basic knowledge of Fuzzy Mathematics and ANN, we detailedly express the way of constructing the FNN which can reflect the information of fuzzy number. In the same time, we use Self Organizing Algorithm and GA to modify the structure and parameters of FNN, hope that the combination of these algorithms can be carried out in many kinds of complex informational problems, such as pattern recognition, quality evaluation, and data extraction and so on.

Meander is a noun that refers to a bend in a sinuous or winding river. Wikipedia notes,
...in Classical Greece the name of the river had become a common noun meaning anything convoluted and winding, such as decorative patterns or speech and ideas [...] Strabo said: "... its course is so exceedingly winding that everything winding is called meandering."
Thus, one might refer to a route as a meander, although the adjectival form meandering is more frequently heard.
Some related adjectives include circuitous, roundabout, tortuous, winding, serpentine, crooked, sinuous, snaky. Some of these are also used as nouns; for example, serpentine meanings include "coiled distillation tube". One might plausibly call a winding route a serpent.
One could also say, "It's rather an excursion" to indicate that a route is unnecessarily roundabout.


Working principle of greenhouse motor
Edit：Weifang Liwang Electric Co., Ltd.UpDate：2019-07-04
Greenhouse motorIt is the integration of reducer and motor (motor). This integration may also be called a gear motor or gear motor. The geared motor is a fixed speed motor. Once the speed ratio is selected, the motor is selected and the output speed is fixed.
The greenhouse motor is mainly used for driving the sunshade net and window opening inside and outside the greenhouse. Its working principle is as follows:
The reduction motor drives the drive shaft to rotate, and the drive shaft drives the A-type gear to rotate, and the gear rotation causes the frame to reciprocate. Because the frame and the push rod are connected together, the push rod and the frame move at the same time. The driving side profile and the push-pull rod are connected by a push rod connecting clamp, and one end of the sunshade is fixed on the driving side profile, thereby shading. With the reciprocating movement of the driving edge profile, the curtain can be opened and closed.
The reducer is used to change the speed and output torque to provide high torque and low speed. Reducer speed ratio=input / output speed, if the revolution ratio is 100, the output torque is about 100 times the input torque. (Rotational speed slows down and torque increases)
One of the heavy parts in the greenhouse motor is the limit device. The quality of the limit device directly affects the stability of the geared motor and the accuracy of the positioning of the system such as curtain drawing and window opening. So how can we determine the quality of the limit device? This requires users to try it by themselves. After buying a new geared motor, first try to check whether the limit device is sensitive before use. After connecting the motor power line and limit signal line according to the manual under no-load state, power on to see if the limit device It is important to be able to cut off the power supply of the motor as required and stop it accurately.

From the late nineteenth century through the beginning of World War II, the best jobs available to African Americans in Portland, Oregon were on the dining cars that came through Union Station and at the hotels around it. Because white-owned businesses were largely closed to people of color, a community of black-owned businesses and social organizations grew in the area surrounding the station. A new exhibit at the Oregon Historical Society explores work and lives of Portland's African American railroad workers and their families just in time for the 2013 Martin Luther King, Jr. holiday and National Black History Month.
"All Aboard: Railroading and Portland's Black Community," an exhibit created by Oregon Northwest Black Pioneers and the Oregon Historical, and funded in part by a grant from Oregon Humanities, focuses on the African American railroad workers in Portland in the 1800's through the 1940's and the community that grew around Portland's Union Station over the years. The interactive exhibit, which was assembled with the help of an advisory committee of former railroad workers, children of railroad workers, and local historians, features period uniforms and articles from historical black newspapers, and places the stories of Portland's railroad workers within the context of Oregon's racial history.
The exhibit opened on Tuesday, January 15th, at the Oregon Historical Society Museum, 1200 SW Park Avenue, Portland, OR, and runs through April 21st.
The museum is open 10 a.m. to 5 p.m. Monday to Saturday and noon to 5 p.m. Sunday. Admission is free for OHS members and residents of Multnomah County, and $5–$11 for nonmembers and nonresidents. On Monday, January 21st, admission is free in honor of the Martin Luther King, Jr. holiday. For a calendar of related events, visit the OHS website.

UNDERSTANDING SURGE PRESSURES IN PIPING SYSTEMS
A surge in pressure within a piping system, known as water or fluid hammer, occurs whenever the linear flow rate of fluid in pipe changes quickly – when pumps start or stop, valves open or close with quick acting actuation devices, or entrapped air moves within the system. The longer the pipe line and the faster the fluid is moving, the greater potential for shock.
Surges in pressure place stress on piping materials and joints and can cause physical movement of the piping system. Engineering designs must incorporate controls that can maintain surge pressures within the piping system's capabilities and eliminate or minimize physical motion of the system. It is very possible to have surge pressures twice as high as normal operating pressure. Long term performance of the piping system can be affected by repetitive shock waves, potentially resulting in leaks and other costly damage.
Some surge pressure problems result from poor piping system design – no matter what material is used for the system. Reducing the pipe size too quickly, for example, can result in surge pressure issues. The system may include 8-inch pipe when entering a tee and reduce down to two 3-inch pipes coming out of the tee. This type of situation creates a surge pressure inside the tee as the fluid has to greatly increase in linear velocity to push the same volume flow rate through a smaller cross-sectional flow area.
Different materials perform differently in surge pressure situations depending upon their strength and elasticity. Understanding the material used in a piping system and designing the system to regulate pressure and fluid flow velocities according to its capabilities are important for the system's long-term performance. Proper sizing of pipe throughout the system, regulation of the speed with which valves and pumps actuate, and incorporation of surge dampening devices can limit the impact of hydraulic shock and keep the total system pressure within the design parameters.
Calculating Surge Pressure
Designers and engineers can control some factors relative to surge pressure – such as pipe diameter and fluid velocity – while factors such as fluid properties are based on the application. Engineers may use the following equation to calculate a piping system's maximum surge pressure:
Surge pressure should always be calculated as an addition to the system's operating pressure. The combined surge pressure and operating pressure must never exceed 1.5 times the system's maximum working pressure.
The values in the tables linked below are based on the above formula at 73°F and the assumption that water flowing at a given rate of gallons per minute will suddenly and completely stop. The surge pressure is approximately 15 percent less at 180°F. Values for fluids other than water may be calculated by multiplying the square root of the fluid's specific gravity.
The tables that follow show carrying capacity and friction loss for Schedule 80 piping and include both independent and dependent variables.
Carrying Capacity and Friction Loss for Schedule 80 Corzan CPVC Pipe (PDF)
Designing to Minimize Surge Pressure
Engineers have several options when designing piping systems to help minimize the negative impact of surge pressure. Properly sizing pipes, for example, is the most effective way to control fluid velocity. The larger the pipe diameter, the slower the fluid velocity for a given volumetric flow rate. This variable should be adjusted to maintain the required flow rate while keeping surge pressure below 1.5 times the piping material's maximum working pressure.
Linear fluid flow velocity within a piping system should generally be limited to 5 ft/s for industrial applications, especially for pipes six inches or larger. Air should never be allowed to accumulate in the system while it is operating. During start up, the fluid velocity within the system should be limited to 1 ft/s while filling or until all air has been flushed out and the pressure brought up to operating conditions. In addition, pumps should never be allowed to draw in air.
Extra protective equipment may be used to prevent surge pressure or water hammer in pipes. Such equipment might include pressure relief valves, shock absorbers, surge arrestors and air vacuum relief valves. Fast-acting valves should always be regulated to help prevent hydraulic shock.
Combining Quality Piping and Proper Design for Reliable, Long-Term Performance
Excessive surge pressure places added stress on materials and joints and can fatigue the system to the point of failure over time. Different materials perform differently in surge pressure situations depending upon their strength and elasticity, which is why it is important to understand the material that will be used for the piping system and properly design the system to avoid costly surge pressure issues.
When properly designed and installed, a Corzan CPVC piping system will provide years of reliable and productive service with minimal life-cycle costs.

What do you expect pdftex to do? It does not change your figure. This is expected behaviour. If you want a "proper" diamond, correct it with the application you used to generate the file. If you just want to convert EPS to PDF I would suggest to use ghostscript. The processing is faster and it's easier to use, especially if you use one of the wrappers like ps2pdf. – Marco Nov 5 '12 at 12:01
1 Answer 1
This is more a question about Stata than it is about LaTeX. You use Stata to generate the graph and pdfLaTeX does not change it. If you open the graph in a viewer that is capable of displaying EPS files (e.g. Ghostview) you will find that the missing edges are already in the EPS.
In Stata there is not much you can do about it, except for explicitly choosing a different marker symbol with the msymbol option, e.g.
sysuse auto
scatter mpg weight if foreign, msymbol(O)
graph export filename, as(eps) preview(off) replace
See help symbolstyle and help scatter##marker_options in Stata for more information about marker symbols.
From what I saw, the triangle, square and diamond marker symbols all have a missing edge as do bars/boxes on bar charts, box plots, histograms.
If you are not familiar with Ghostview: Ghostview is a command-line only programme, but you can use GSView for instance as a GUI on Windows. Some programs like SumatraPDF can also display EPS files, but they also use Ghostview as a backend AFAIK.
It is sometimes helpful to also post on which platform (Windows, I presume) and with which software versions (Stata 11, 12?, Word, Acrobat/PDFMaker) and tex distributions (MiKTeX 2.9?) you are working. In this case it does not make much of a difference, I guess, except that Stata 12 on Windows is now capable of exporting PDF directly (on Mac you could do that at least with v11 already and on Linux I don't know). When exporting to PDF with Stata 12 on Windows, the diamonds are missing an edge as well, but strangely the squares don't (while they do when exporting to EPS - at least that's what I saw when testing it ad hoc).
It could be worthwhile to post this as a bug to Stata Corp. by the way.

In its annual Oil and Gas Review [PDF] published on December 23, 2019, the Alberta Securities Commission (ASC) highlighted concerns related to production disclosure by reporting issuers engaged in oil and gas activities. As our clients head into annual disclosure season, we have summarized certain key guidance points relevant to oil and gas reporting issuers currently readying their continuous disclosure filings, news releases and investor presentations.
Disclosure is required by each product type produced
The ASC reminded reporting issuers that, in order to comply with National Instrument 51-101 – Standards of Disclosure for Oil and Gas Activities, production disclosure must include production based on product type produced, as measured at the first point of sale (i.e., the first point after initial production at which there is a transfer of ownership). If reporting issuers disclose an aggregate production amount using boe/day or a production amount for a by-product (or hydrocarbon component), such as condensate, they will also need to disclose the constituent or related product types that were produced.
This clarification is noteworthy as it rejects the relatively common practice among oil and gas reporting issuers of disclosing an aggregate production amount using boe/day without including the constituent product types produced, and of disclosing by-product or other fluids production (for example, condensate production) without also disclosing the product types produced.
To comply with the ASC's expectations, reporting issuers should ensure that any production disclosure includes each product type and quantity measured at the first point of sale. Product types include conventional natural gas, light crude oil and medium crude oil combined, bitumen, natural gas liquids and shale gas. So, in the case of condensates, it is necessary to also disclose natural gas liquids with which they are associated. Once this "minimum disclosure requirement" is met, reporting issuers can disclose as supplemental disclosure associated by-products and hydrocarbon components at the first point of sale, as well as estimated quantities of product types, by-products and hydrocarbon components expected to be recovered beyond the first point of sale. Accordingly, issuers may not need to significantly change how they are currently disclosing production amounts, so long as the disclosure is expansive enough to include production amounts using product types.
While some reporting issuers may object to the perceived low value of breaking out the overall composition of production by all product types, the ASC cautions that reporting issuers must ensure that disclosure is not misleading where certain product types are excluded – for example, where there are marketable quantities of a particular product type at the first point of sale, even if that product type is of lower value.
Other areas of improvement:
In the Oil and Gas Review, the ASC also noted the following additional concerns relating to production disclosure:
- quantities measured elsewhere than the first point of sale
- disclosure of product type ratios (for example, by percentages) rather than by quantity of each product type – the quantities of production should be disclosed in the same document in which those ratios are disclosed


Is finding a solution for a problem in a given context is an attempt to find a solution for the problem in another context?
For example, it seems some of the hardest problems of real analysis were not solved till their solutions were found in the context of geometry.
Update: I think it makes the question more clear if I provide an example. Let's say I want to prove if x+y=x+z, then y=z, where x,y,z $\in F$, where $F$ is a an algebraic field with operation "+". For example for this problem I can think of context where solution exits and that would be the ring of integers. If 1+2=2+1 then I can show 1=1. Now once this solution is found using this context of integers I can now apply this to the original problem in the context of field.
Now what I was asking was that should such a solution exists in some contexts (context as used in example above) for a problem to be solvable.
I do not know the background science behind this but it would be great if references can be introduced so I can get to know the right terminology.

 It may help to rephrase the question a bit. At the moment, it looks almost trivial: if a problem has no solution in any context – i.e., not anywhere – then it has no solution. Presumably, that's not what you're getting at, though; so, it would help if you could expand on what you mean by 'context', and on what it takes to have a solution in a context. Constructivists hold that you can't prove 'There's such-and-such a number', except by producing a number that indeed is such-and-such. (In particular, you can't prove it by contradiction.) Is your question related to that viewpoint in any way? – MarkOxford Nov 12 '17 at 13:47
 - Do you mean : 'Is the non-solvability of a problem in any context in a given domain an indication that its solution, if any, is to be found in a context in a different domain?' E.g., does the non-solvabilty of a problem in theology indicate that its solution - or dissolution - belongs to physics? – Geoffrey Thomas Nov 12 '17 at 14:22
 - _USER_ By a context I mean something like a domain and by domain I mean something that contains similar objects. For example, an algebraic filed is a domain where objects existing in it share certain characteristic. I think Geoffrey Thomas comment is very close to what I want. – Mathnewbie Nov 12 '17 at 19:52
 - _USER_ Yes very close to what I want but a solution to a non-solvable problem of theology could exist in physics or any other domain that has not been yet explored or discovered. Of course the domain must have certain characteristics for example there should exist a one-to-one correspondence between the objects of the two domains. – Mathnewbie Nov 12 '17 at 19:55
 - I suppose I still don't really understand the question. If a problem has no solution in any domain, then where would the solution be? Are there sets that aren't domains, because their elements aren't similar enough to one another? Or is the idea that there are 'meta-domains' or 2nd-order domains? If we find no solution in any of the 1st-order domains of a particular 2nd-order domain, then we might move on to a different 2nd-order domain and look through its 1st-order domains for a solution. – MarkOxford Nov 12 '17 at 21:00
To answer the second part of your question 'it seems that the solution was found and then the question answered' Yes, that is the way it's done most of the time because it is much simpler once you know the outcome. You can simply do Sherlock Holmes eliminate all the impossible until all you're left with is the possible. And that would be a good approach I would say it is a better way than how scientists handle problems today. They did not eliminate the possible they actually attempted to explain reality with the possible even though it is impossible, such as dark energy and basically everything else in science
If a problem is worth having, it can be solved. You seem to be talking about how new techniques have been needed to solve seemingly insoluble problems, like say Fermat's last theorem.
There seem to be mistakes in tense or spelling that make your question confusing, and I am struggling to understand what you are actually asking.
It puts me in mind of how for Newton it was essential to put his theorems and proofs in geometric forms, as geometry was considered most fundamental of maths by the Greeks. Even though, this was difficult and awkward to do and made it harder to see the implications of what he did. Soon after geometry lost it's'supremacy'.
To what extent does the world divide cleanly into distinct contexts? In the end isn't there only one context, our minds, which unify all contexts? We switch language-game to adapt to each
If I correctly understand your mathematical example, then mathematics provides many examples of the following type:
A problem has no solution in the context, where the problem is stated. But the problem has a solution in a broader context.
For example take the problem:
1) Find all solutions of the quadratic equation x^2+1=0.
The problem is stated in the context of real numbers. But the problem has no real solutions. Instead the problem has two solution, namely +i and -i, from the context of complex numbers.
2) Similarly, take the problem: Find all solutions of the quadratic equation x^2-2=0. The problem has no solution in the rational numbers, but it has two solutions in the real numbers.

Impact of Trade Union on Productivity of Teachers in Public and Private Primary Schools in Cross River State, Nigeria (Published)
The study investigated the impact of trade union on productivity among teachers in public and private primary schools in Cross River state. Specifically, the study compares productivity of teachers in private and public primary schools in the study area. Survey design was deployed in the study while cluster random sampling was used to select 180 pupils and purposive sampling technique to select six (6) key informants. Survey interviews and key informant interviews were used for data collection. The analysis of data involved use of percentages, mean and chi-square and transcription of views of the key informants. The study revealed that teachers in private primary schools are more productive than their colleagues in public schools based on indices of productivity such as attendance to school, attendance to classes, average number of lessons held per day and involvement in extra lessons. The study also found a significant difference in school attendance between the public and private primary schools in the study area as the computed chi-square value of 2.222 was greater than the critical value of 1.543 on 1 degree of freedom and confidence level of 0.05. Also there was a significant difference in regular class by teachers in the public and private primary schools as computed chi-square value of 46.723 was greater than the critical value of 44.416 on 1 degree of freedom and confidence level of 0.05. The study therefore recommends regular audit of teachers, strict monitoring on the job, training and retraining and inclusion of teachers' productivity as one of the core aims of trade Unions.


text: Locus of Control refers to the extent to which individuals believe that they can control events that affect them. Individuals with a high internal locus of control believe that events result primarily from their own behaviour and actions. Those with a high external locus of control believe that powerful others, fate, or chance primarily determine events. Those with a high internal locus of control have better control of their behaviour and tend to exhibition more political behaviours than externals and are more likely to attempt to influence other people; they are more likely to assume that their efforts will be successful. They are more active in seeking information and knowledge concerning their situation than do externals. The propensity to engage in political behaviour is stronger for individuals who have a high internal locus of control than for those who have a high external locus of control.

If when creating a new folder or copying file or folder on your Windows 11 or Windows 10 device or on an external drive attached to your system, and you get an error prompt with the message Error Copying File or Folder Catastrophic Failure, then this post is intended to help affected PC users with the most suitable solutions.
This issue is most likely to occur due to the following reasons;
- Missing or corrupt system files
- Write-protected disk
- No file or folder permission
- Low disk space
What does Catastrophic failure mean when copying files?
If the Catastrophic Failure has occurred when copying files/folders on your Windows 11/10 device, it's likely caused by missing system files or broken system registry structures. This is a critical sign of an unstable system that is typically caused by improper maintenance of the computer.
Error Copying File or Folder, Catastrophic failure
If you have run into the Error Copying File or Folder Catastrophic Failure issue on your Windows 11/10 PC, you can try our recommended solutions below in no particular order to resolve the issue on your device.
- Run File and Folder Troubleshooter
- Assign Full Control permission to the file/folder
- Clear Temp files
- Format destination drive to exFAT or NTFS
- Create a new User Account
Let's take a look at the description of the process involved concerning each of the listed solutions.
Before you try the solutions below, you can do the following, and after each task see if you can copy the file or folder without issues:
- Restart your PC.
- Make sure the disk is not write-protected.
- Check for updates and install any available bits on your Windows 11/10 device.
- If you started experiencing the issue after a recent Windows update, you can perform System Restore or uninstall the update.
- Run SFC scan.
- Optimize drive.
1] Run File and Folder Troubleshooter
Since the Error Copying File or Folder Catastrophic Failure issue is file/folder-related, you can begin troubleshooting to fix the error on your Windows 11/10 device by running File and Folder Troubleshooter – among other fixes, the automated wizard will help you fix issue when you try to copy, move, rename, or delete a file or folder.
2] Assign Full Control permission to the file/folder
If you have insufficient permission for the file/folder copy operation, you are likely to enounter the issue in hand. In this case, to resolve the issue you need to assign Full Control permission to the file or folder that's throwing the error.
3] Clear Temp files
Insufficient disk space due to copying large file or folder can give rise to this copy error. In this case, to resolve the issue, you can free up disk space by clearing temporary files that end up consuming lots of storage space. We recommend you use any third-party disk analyzer software for Windows 11/10 to get a granular view of what might be hogging storage space and the location on the drive; and then you can run Disk Cleanup to clear unnecessary files on the drive.
Once done, you can try the copy operation again and see if the issue you're currently facing is resolved. If not, try the next solution.
4] Format destination drive to exFAT or NTFS
The error in highlight can occur when you try to copy an item larger than 4GB to a partition with the FAT32 file system as you can easily copy up to 2TB to a FAT32 drive but the caveat is an individual file cannot exceed 4GB. If this is the case, you can either compress the file using any free File Compression & Extraction software and then try the copy operation again; or simply format destination drive to NTFS or format to exFAT file systems that can accommodate such large files.
5] Create a new User Account
This is another viable solution (more of a workaround) that worked for most affected PC users. This requires you to simply sign into another user account on your Windows 11/10 device, and then perform the copy operation within the account. You can create a new local user or administrator account if need be.
Hope this helps!
How do you fix Catastrophic failure?
To successfully fix catastrophic failure issues when installing Windows On-Premise Poller, do the following:
- Navigate to All Users from your Windows machine.
- In the All Users folder, right-click Shared Documents or Public Documents.
- Select Properties.
- In the General tab, uncheck the Read-only checkbox.
- Click Apply > OK.
Why is my laptop showing error copying file or folder?
If you encounter an unspecified error while copying file or folder from a PC to an Android phone, it is possible that the Android SD card is corrupted. In this situation, you can go to check whether the SD card can work as normal on the phone. If not, you will need to make a data recovery.
- Error Copying File or Folder, The requested resource is in use
- Error copying file or folder, The requested value cannot be determined
Why some files are not copying?
If copy-paste is not working on your Windows 11/10 device, it could be due to a temporary glitch, software interference, device drivers, or a corrupted system file, etc. When this issue occurs, the Copy and Paste options are grayed out in the right-click context menu, and the keyboard shortcuts (Ctrl+C and Ctrl+V) do nothing.

What is a Waterfall Chart?
The waterfall chart shows how an initial value is affected by a series of intermediate positive or negative values to arrive at a final value.
Imagine that you're trying to show the different positive and negative components which result in company profit like in the table below.
The waterfall chart makes it easy for your audience to visualize and interpret the different components and their effect on the total value.
With the waterfall chart above, people can see both the breakdown and impact that product revenue, service revenue, fixed costs and variable costs have on profit.
We can also add additional details by adding columns or stacks like in the example below where we show the breakdown of variable costs.
