settings en Comparing Configuration Files Comparing configuration (i.e. ini, preferences, config, etc.) files is not as simple as comparing say C source file. Typically in a config file the order doesn't matter so Line A Line B...... Is the same as Line B Line A...... Hence all the usual Diff tools mistakenly say files are different when functionally they are the same. Comparing something like the /etc directory on two Linux machines thus involves a lot of hand checking of functionally identical files. One solution to this is to sort the lines in the files first. The different files listed by a Diff program are then only those with real difference (assuming you turn off whitespace difference). This can be done very simply with KDiff3 which has the option to include a file preprocessor before the compare. This is found in KDiff3 in settings, diff tab. So by adding a file preprocessor such as for example: perl -e 'print sort <>' We can sort the file lines before the compare. On linux and windows this can be even simpler as they have native sort commands which work too. So all that needs adding in this case to the preprocessor setting is just "sort". Click the image above to see a screenshot of the settings dialogue. Caveats Lines are reordered so editing in a separated editor is a better idea than merging in KDiff3. Single settings that span multiple lines and multiple settings on a single line may show as different when functionally the same Tags: iniconfigsettingsdiffkdiff Wed, 24 Sep 2014 16:55:10 +0000 Malc 33 at


Cleaning Tips
Please see notes of caution below before attempting cleaning
 1. To clean the laminate table top surface surface, use a damp cloth or sponge and a mild soap or detergent. Rinse thoroughly with warm water and wipe dry.
 5. Hot pans and heat-producing appliances (such as electric skillets), when set directly upon countertops, can mar the product's beauty. Always use a heat shield, hot pad or trivet.
Recommended Cleaners
 Glass Plus®
 Mr. Clean®
 Formula 409®
 Isopropyl Alcohol (Isopropanol)
Damaging Cleaners
Cleaners that can cause damage to the laminate surface include, but are not limited to:
 Hydrochloric Acid
 Muriatic Acid
 Hydrogen Chloride
 Sulfuric Acid
 Oleic Acid
 Oil of Vitriol
 Hydrofluoric Acid
 Rust Remover
 Phosphoric Acid
 Sodium Hydroxide
 Caustic Soda
 Caustic Lye
 Soda Lye
 Pumice (abrasive)
Notes of Caution
 1. Prolonged exposure of the laminate surface to acetone or bleach will cause discoloration. Always rinse laminate surface after cleaning. Failure to rinse after cleaning can cause damage, even if only a small amount of cleaning solution remains on the surface. A dry residue may be invisible, however moisture from cups or drinks can reactivate it and result in permanently etched scars or stains over time.
 2. Acidic or abrasive cleaners can damage laminate surfaces – do not use them.
 3. Drain cleaners containing lye will permanently damage the laminate surface. If you spill drain cleaner, wipe it up immediately and rinse several times with water.
 4. Hair, textile and food dyes can cause permanent stains. If dye is spilled, wipe up immediately with dishwashing detergent or an all-purpose cleaner.
 5. Never place pots or dishes directly from the oven or burner on an unprotected laminate surface; such extreme heat can cause cracking or blistering.
 6. Do not work with oven cleaners on an unprotected laminate top. Wipe spills away promptly and rinse several times with water.
 7. Rust removers contain harsh chemicals which will quickly cause permanent damage. If a spill occurs, wipe off all residue immediately, wash thoroughly with soapy water and rinse several times.
 8. Steel wool and other abrasive pads will damage the laminate surface. Do not use them for cleaning and do not store steel wool pads on your laminate; the metal can rust and leave stains.
 9. Toilet bowl cleaners contain harsh chemicals that can cause permanent damage. If spills occur, wipe up immediately, wash the surface with soapy water and rinse several times.
 10. Remember, sharp objects can damage the surface of any laminate: marring its beauty and lowering wear and stain resistance. Although high-pressure laminates are somewhat resistant to scratching, the surface can be damaged even under normal use. Laminate may need occasional dusting depending on where it is used. To keep the surface beautiful, use an oil free furniture spray. Remember to clean the spray off several times a year to prevent build up. Furniture polish may also help hide fine scratching in the surface.

Is it made of earth or brick? Â This is a common distinction in the world of wood-fired ovens and comes with a whole slew of assumptions. Â "Earth ovens are cheaper, easier to build but less durable." Â "Brick ovens are expensive, harder to build but more professional and will last longer." Â The oven build documented below is an exploration of the combination of these techniques to leverage the advantages of each. Â We use earth where its sculptural quality allows us to perfectly mold it to the shape that we desire. Â We use brick where it will give a good durable surface for cooking and in the entrance way to withstand the abuse of heated and passionate cooking. Â The bookÂ Build Your Own Earth Oven provides further reference for these techniques.

The wood thrush has lost 43 percent of its population over the past 40 years, making it a species of conservation concern. As with other species in decline, the main culprit seems to be the loss and fragmentation of woodland habitats, largely due to development. Ongoing research at the University of Delaware compares the breeding success of wood thrushes at a university woodland preserve and in a nearby neighborhood.
Roth discovered that loss of habitat hasn't deterred the remaining wood thrushes from summering in Delaware. However, many must try to breed in less than desirable conditions; in the 1980s, Roth studied a sizable population of wood thrushes in the wooded Newark neighborhood of Arbour Park. These birds had the usual two to three nests with three to four eggs per year, but raised significantly fewer young than wood thrushes breeding in the UD Woods, located just two miles away. And, unlike the thrushes at the UD Woods, few of the banded adults in Arbour Park returned there the next year, which was more likely an indication of bird dissatisfaction than mortality.
"UD Woods' leaf litter fosters excellent food resources, such as larval and adult insects, earthworms and millipedes. And on the edge of the woods, the birds can forage for berries from spicebush, elderberry and other shrubs," notes Roth. "A suburban neighborhood often doesn't provide such an abundant food supply, much less native trees and shrubs for nesting and shade."
While many nests were lost to predation at Arbour Park, the nests there also were more frequently parasitized by the brown-headed cowbird. It lays its eggs in the nests of wood thrushes and some other song birds, often removing a host's egg for each one laid. The unwitting host incubates the cowbird eggs and feeds the cowbird chicks along with her own. The negative effect on wood thrushes is the loss of eggs.
"Cowbirds are more apt to parasitize nests in small forest fragments, wooded neighborhoods and other edge habitats created by humans than in deep deciduous forests, where the wood thrush thrives," says Roth. "Don't blame the cowbirds; we created the favorable conditions for them."

Define Titrimetric Method - 2, 6 Dichlorophenol Indophenol Method?
The titrimetric method is a redox titration method which depends on the reduction of the blue dye 2,6 dichlorophenolindophenol to a colourless leuco compound by ascorbic acid in solution or in extracts made out of foodstuff. Ascorbic acid, as you have already studied, is a strong reducing agent because of which it reduces the dye 2,6 dichlorophenolindophenol and itself gets converted to dehydro ascorbic acid. After equivalence point is reached the next drop of dye gives a pink colour to the solution indicating the end point. The dye in this titration is coloured in the oxidized form and colourless in the reduced form. Also the dye is pink in acidic solution and blue in alkaline solution.
The reaction involved in this method is highlighted in Figure
2396_Define Titrimetric Method - 2, 6 Dichlorophenol Indophenol Method.png
Figure: Conversion of ascorbic acid to dehydro ascorbic acid
In acidic solution the pink dye is reduced to a colourless substance in presence of ascorbic acid. The solution remains colourless as more dye is added until all the ascorbic acid has reacted. As soon as the next drop of dye solution is added the solution becomes light pink due to excess dye indicating that the end point of the titration has reached. The solution of ascorbic acid or its extracts are prepared in metaphosphoric acid or glacial acetic acid or a mixture of the two. The acid prevents the oxidation of ascorbic acid due to oxygen in the atmosphere which is faster in presence of metal ions like Fe3+ and Cu2+. Metaphosphoric acid can also form complexes with metal ions which reduces the catalytic oxidation of ascorbic acid. In foods, metaphosphoric acid releases the ascorbic acid from proteins and inactivates ascorbic acid oxidase.

How To: Format a real number relation in a note?
SOLVED
Re: How To: Format a real number relation in a note?
Martin's getting sneaky trimming the digits as a string instead of a real number. This is a great trick... if only more people understood some of the nifty stuff you can do with relations. Unfortunately it's one of those rare arts that few seem to know about.
Martin is really giving a goldmine of information here but you have to dig deep to fully appreciate it.
The four functions Martin is using are:
 - FLOOR - rounds any real number down to the next closest value with the number of digits specified. The format is floor(real number,number of digits to round to)
 - ITOS - the "integer-to-string" function. The format is just itos(integer).
 - EXTRACT - grabs a portion of a string. The format is extract(string, start position, number of chars to extract)
 - STRING_LENGTH - provides the length of a string in characters. The format is string_length(string)
But you really have to examine the code to truly see the beauty here.
The itos function only converts integers to strings. It cannot handle decimal values (real numbers). If you wrote x = itos(12.98765) you'd end up with x="12". The decimal values would be discarded. Therefore, Martin's relations incorporate a thoughtful bit of math to handle this problem.
First, he sets the variable number_digits to 3. Then, first set a variable for the number digits after the decimal to preserve. He uses the floor function to round down the real number x which starts at 12.98765. Once this function has completed it's work, x is 12.987.
Next, Martin uses the itos function. He multiples 12.987 by 10 to the power of 3 (or 1000) to remove the decimals. Thus, once itos has done it's work, the value has changed from 12.987 to "12987" (now a string with the decimal removed)
In the last line of the relations, Martin uses extract and the string_length functions together. This final line writes out the first two characters of the string "12987" which are just "12". Next a dot (.) is written out. Finally, the last 3 characters of the string ("987") are written. Together this is "12.987" which completes the conversion from 3 digit real number to string".
The whole thing is very, very clever. Thanks for posting this Martin.
Thanks!
-Brian
PS: There's one very slight problem though... I'll leave it to any curious readers to figure it out. Here's a hint... it has to do with the "6" in the original value of x which was 12.98765 Maybe someone will catch it and demonstrate the fix.
Re: How To: Format a real number relation in a note?
Oh, I definitely appreciate Martin's approach. In the day, I was very into programming DBASE III and IV and completely understand the approach and even the syntax.
The use of "FLOOR" might be a bit troubling since a "ROUND" should be available to round to either the "even principle" or the conventional 1-4=down and 5-9=up. But even thsat could be "relationed" to resolution.
Why a "new empty part"?
This stuff has to be written somewhere; No?
Re: How To: Format a real number relation in a note?
Yep... the use of Floor was the "one very slight problem". Martin could've incorporated a test to do the rounding better. As it stands 12.98765 rounds to 12.987 when it should round to 12.988. A simple if/then/else test and the addition of the CEIL command could resolve this.
But that's just being nitpicky...
Re: How To: Format a real number relation in a note?
Brian, I'd love to hear this from the "horse's mouth" so to speak...
Quite some time ago, I heard it was NASA that came up with the Round "5" to Even rule. Is this a fact?
n.nn5 round to n.nn(even) where n.nn(1-4) rounds down and n.nn(6-9) round up.
And where does that leave n.nn51 in relation to n.nn?
Its a great rule but the source has remained ambiguous. I'd love to confirm this with references.

Re: How To: Format a real number relation in a note?
Antonius,
of course you can use relations in any part. I thought the most easiest method for testing is using "new empty part".
To implement the conventional 1-4=down and 5-9=up "ROUND" principle, it is necessary to modify relations slightly, see below.
/* input variables
number_digits=3
x=12.98799
x=x+5/10^(number_digits+1)
/* output variables
t1=floor(x,number_digits)
t2=itos(t1*10^number_digits)
t3=extract(t2,1,string_length(t2)-number_digits)+"."+extract(t2,string_length(t2)-number_digits+1,number_digits)

Re: How To: Format a real number relation in a note?
Very clever!
Re: How To: Format a real number relation in a note?
Yes indeed - adding 0.5 (or 0.0005, depending on the number of decimals you're rounding to) is a much neater technique than if/else. I've used that before with Excel's INT() function.
Re: How To: Format a real number relation in a note?
Unfortunately, "the horse" can neither confirm nor deny that NASA is responsible or the rounding rule you mentioned.
One of my children pulled me aside the other day and said: "Dad... is there life on other planets?" Of course I said "We don't know yet but we're looking... and personally I believe there is life on other planets just by the sheer mathematical probability. I think we'll eventually find it."
This seemed to be a reasonable and, I hoped, thoughtful answer. When I asked why the child wanted to know, he said: "Well Uncle Danny (a huge redneck related to my ex-wife) said NASA already has proof aliens exist but they keep it secret from everyone. Is that true?"

Re: How To: Format a real number relation in a note?
I just caught this thread and was a little excited to see if PTC had actually added a much needed function. But alas .... no .... just another verification that they don't listen to the users.
We have been using this "trick" to convert parameters that are real numbers to notes in drawings since I started. The function we have asked for is RTOS (Real to String) with a way to control the number of decimals.
The actual answer to the posted question is .... there is no direct method .... just Martin's "trick".


text: The effect of placing a stationary airfoil downstream of a pitching airfoil in a tandem configuration was investigated using computational fluid dynamics. A finite-volume URANS solver was employed to simulate the flow field. An optimization study was performed at the low Reynolds number of 30,000 for SD7003 airfoils using a genetic algorithm. Three artificial neural networks were coupled with the genetic algorithm to reduce the computational cost. The optimization process was used to find the optimum design parameters in order to maximize lift to drag ratio of airfoils together in addition to the thrust coefficient of the hindfoil. It was found that a significant improvement of 174% and 15% could be achieved for the thrust coefficient of static hindfoil and L/D of the combined airfoils respectively in tandem configuration over single airfoils at optimum values of design parameters.

Encyclopedia - Distinguished Service Cross (U.K.)
The British Distinguished Service Cross medal was awarded by military authorities to serving members of the Royal Navy for meritorious actions in the face of the enemy.
Instituted in 1901 as the Conspicuous Service Cross the medal was awarded to warrant and subordinate officers; it was renamed the Distinguished Service Cross (DSC) in October 1914 and made available to all Royal Naval personnel below the rank of Lieutenant Commander.
Some 1,983 DSCs were awarded during the course of the First World War. From 1916 a Bar was made available to denote formal recognition of further acts of merit to existing DSC holders.
The medal, which was made of silver, was 41mm in height and 35mm wide. The obverse of the medal showed the Royal Cypher on the circular central medallion surmounted by a crown; the reverse was plain other than for a hallmark with the year of the war engraved on the lower arm.
A "blimp" was a word applied to an observation balloon.

High reliability requirements
Generator systems described in this technical article are applicable to healthcare requirements, as well as other facilities that may require a high degree of reliability. The electrical supply for data centers, financial institutions, telecommunications, government and public utilities also require high reliability.
Generators applicable to high reliability requirements of healthcare and other facilities

Threats of disaster or terror attacks have prompted many facilities to require complete self-sufficiency for continuous operation.
Note that relay protection of a generator is not covered here because this is very complex subject and it has been previously described in several articles (this one for example).

1. Types of Engines
Many generator sets are relatively small in size, typically ranging from several kilowatts to several megawatts. These units are often required to come online and operate quickly. They need to have the capacity to run for an extended period of time.
The internal combustion engine is an excellent choice as the prime mover for the majority of these applications.
Gas internal combustion engine generator unit
Figure 1 – Gas internal combustion engine generator unit
Diesel-fueled engines are the most common, but other fuels used include natural gas, digester gas, landfill gas, propane, biodiesel, crude oil, steam and others.
Some campuses and industrial facilities use and produce steam for heating and other processes. These facilities may find it economically feasible to produce electricity as a byproduct of the steam production.
These installations would typically be classified as a cogeneration facility producing a fairly constant power output and operating in parallel with the electric utility system.
Go back to Content Table ↑
2. Types of Generators
Generators can be either asynchronous or synchronous. Asynchronous generators are also referred to as induction generators. The construction is essentially the same as an induction motor. It has a squirrel-cage rotor and wound stator.
An induction generator is a motor driven above its designed synchronous speed thus generating power. It will operate as a motor if it is running below synchronous speed. The induction generator does not have an exciter and must operate in parallel with the utility or another source.
The induction generator requires VARs from an external source for it to generate power. The induction generator operates at a slip frequency so its output frequency is automatically locked in with the utility's frequency.
An induction generator is a popular choice for use when designing cogeneration systems, where it will operate in parallel with the utility.
This type of generator offers certain advantages over a synchronous generator. For example, voltage and frequency are controlled by the utility; thus voltage and frequency regulators are not required.
In addition, the generator construction offers high reliability and little maintenance. Also, a minimum of protective relays and controls are required. Its major disadvantages are that it requires VARs from the system and it normally cannot operate as a standby/ emergency generator.
Synchronous AC generator with PMG excitation
Figure 2 – Synchronous AC generator with PMG excitation (PMG stands for Permanent Magnet Generator)
Synchronous generators, however, are the most common. Their output is determined by their field and governor controls. Varying the current in the DC field windings controls the voltage output.
The frequency is controlled by the speed of rotation. The torque applied to the generator shaft by the driving engine controls the power output. In this manner, the synchronous generator offers precise control over the power it can generate.
In cogeneration applications, it can be used to improve the power factor of the system.
Go back to Content Table ↑
3. Generator Fundamentals
A generator consists of two primary components, a prime mover and an alternator. The prime mover is the energy source used to turn the rotor of the alternator. It is typically a diesel combustion engine for most emergency or standby systems.
In cogeneration applications, the prime mover may come from a steam driven turbine or other source. On diesel units, a governor and voltage regulator are used to control the speed and power output.
The alternator is typically a synchronous machine driven by the prime mover. A voltage regulator controls its voltage output by adjusting the field. The output of a single generator or multiple paralleled generator sets is controlled by these two inputs.
The alternator is designed to operate at a specified speed for the required output frequency, typically 60 or 50 Hz. The voltage regulator and engine governor along with other systems define the generator's response to dynamic load changes and motor starting characteristics.
Generators are rated in power and voltage output. Most generators are designed to operate at a 0.8 power factor. For example, a 2000 kW generator at 277/480 V would have a kVA rating of 2500 kVA (2000 kW/0.8 pf) and a continuous current rating of 3007 A (2500 kVA / 480 V × √3).
Typical synchronous generators for industrial and commercial power systems range in size from 100–3000 kVA and from 208 V–13,800 V. Other ratings are available and these discussions are applicable to those ratings as well.
Generators must be considered in the short-circuit and coordination study as they may greatly impact the rating of the electrical distribution system.
This is especially common on large installations with multiple generators and systems that parallel with the utility source. Short-circuit current contribution from a generator typically ranges from 8 to 12 times full load amperes.
The application of generators adds special protection requirements to the system. The size, voltage class, importance and dollar investment will influence the protection scheme associated with the generator(s). The mode of operation will influence the utility company's interface protection requirements.
Paralleling with the electric utility is the most complicated of the utility inter-tie requirements. IEEE ANSI 1547 provides recommended practices.

4. Generator Systems
4.1 Emergency Standby Generator System
There are primarily three types of generator systems. The first and simplest type is a single generator that operates independently from the electric utility power grid. This is typically referred to as an emergency standby generator system.
Figure 3 shows a single standby generator, utility source and a transfer switch. In this case, the load is either supplied from the utility or the generator. The generator and the utility are never continuously connected together.
This simple radial system has few requirements for protection and control. It also has the least impact on the complete electric power distribution system.
It should be noted that this type of generator system improves overall electrical reliability but does not provide the redundancy that some facilities require if the generator fails to start or is out for maintenance.
Emergency Standby Generator System
Figure 3 – Emergency Standby Generator System
Go back to Content Table ↑
4.2 Multiple Isolated Standby Generators
The second type of generator system is a multiple isolated set of standby generators. Figure 4 shows multiple generators connected to a paralleling bus feeding multiple transfer switches. The utility is the normal source for the transfer switches.
The generators and the utility are never continuously connected together in this scheme.
Multiple generators may be required to meet the load requirements (N system). Generators may be applied in an N+1 or a 2N system for improved system reliability.
Multiple Isolated Set of Standby Generators
Figure 4 – Multiple Isolated Set of Standby Generators
In an N system, where N is the number of generators required to carry the load. If a generator fails or is out for maintenance, then the load may be dropped. This is unacceptable for most critical 24/7 operations.
In an N + 1 system, N is the number of generators needed to carry the load and 1 is an extra generator for redundancy. If one generator fails to start or is out for maintenance, it will not affect the load.
In a 2N system, there is complete 100% redundancy in the standby generation system such that the failure of one complete set of generators will not affect the load.
Multiple generator systems have a more complex control and protection requirement as the units have to be synchronized and paralleled together. The generators are required to share the load proportionally without swings or prolonged hunting in voltage or frequency for load sharing.
They may also require multiple levels of load shedding and/or load restoration schemes to match generation capacity.
Go back to Content Table ↑
4.3 Multiple Generators Operating in Parallel with Utility System
The third type of system is either one with a single or multiple generators that operate in parallel with the utility system. Figure 5 shows two generators and a utility source feeding a switchgear lineup feeding multiple loads.
Multiple Generators Operating in Parallel with Utility System
Figure 5 – Multiple Generators Operating in Parallel with Utility System
This system typically requires generator capacity sufficient to carry the entire load or sophisticated load shedding schemes. This system will require a complete and complex protection and control scheme. The electric utility may have very stringent and costly protection requirements for the system.
IEEE standard 1547 describes the interconnection requirements for paralleling to the utility.

The Gigantic BirdLogic puzzles require you to think. You will have to be logical in your reasoning.
The three rowed their boat towards the ship. Even before they were half-way there, a gigantic bird swooped down on them and plucked them up. They were carried to a distant land where they were deposited in a nest high in a tree.
From the statements that follow, what was the wing span of the gigantic bird and how far did it carry the three sailors?
1. If the wingspan of the gigantic bird was either 20 or 30 metres wide, it carried the three sailors for 50 leagues.
2. If the gigantic bird carried the three shipmates 75 leagues, its wingspan was not 40 or 50 metres wide.
3. If the wingspan of the gigantic bird was 40 or 50 metres wide, it carried the three sailors 75 leagues.
4. If the gigantic bird's wingspan was not 40 or 50 metres wide, then it was 20 or 30 metres wide.
AnswerThe bird's wingspan was 20 or 30 metres wide; it carried the shipmates 50 leagues.

Ododu is a constructed language that is based on the following presumptions.
- The universe is comprised of conscious entities that create and use language.
- The universe can be described in terms of certain foundational characteristics or relations. These characteristics are elemental in that they comprise units of meaning called foundational morphemes, that cannot be subdivided into any combination of smaller units of meaning.
- Each foundational morpheme can be optimally represented by a foundational grapheme that is both an ideogram and a pictogram. Such a grapheme is independent of any particular language and it conveys some sense of its meaning through a pictorial resemblance of that fundamental unit of meaning.
- Each foundational morpheme – grapheme pair can also be represented by a unique sound unit called a phoneme.
The Ododu language comprises four primary vowels each of which represents a foundational morpheme – grapheme – phoneme unit. These four primary vowels represent the four foundationally different types of relation and hence denote the initial and most primordial characterization of ourselves and the universe. They can be viewed as representing my personal reference frame or a view of the universe from my perspective.
There are also four additional secondary vowels which also represent foundational morpheme – grapheme – phoneme units, and which are, in a sense, reflections of the four primary vowels. They can be viewed as an external reference frame or a view of the universe from a different perspective than mine. For example, the two perspectives might describe the differences in how you and I look at the universe and/or each other.
Each of the four primary vowels can interact with each of the four secondary vowels to generate 16 consonants. In our example, this will describe how each of the elements in my reference frame (my language) will change with respect to changes in the elements in your reference frame (your language) when we both look at and describe some other event in the universe. Each consonant has a unique phoneme and is represented by a unique pictogram. The consonants also are associated with unique morphemes that are related to interactions of the morphemes of the constituent vowels, but which stand alone as archetypal concepts that transcend the meanings of the constituent vowel morphemes or various combinations of the constituent morphemes.
All 24 single letters are represented by graphemes that are non homeomorphic or topologically invariant with respect to each other. Thus no single letter grapheme can be converted into any other single letter grapheme by manipulation of its shape or size. It is further assumed that the eight vowel graphemes are the most fundamental archetypal symbolic forms that can be produced and that consequently they represent the foundational structure and form of the universe itself.
The 16 single letter consonant graphemes are constructed via a serial subsumptive procedure wherein each subsequent consonant grapheme contains all prior graphemes. This process is analogous to the initial morphogenetic development of living cells in biology and hence represents a linguistic process for the development of a language that approaches the goal of a universal language. As the complexity of each sequential grapheme increases they begin to look like the hieroglyphs of many of the languages of ancient peoples and cultures.

Water System Troubleshooting
It can be frustrating when your caravan water system isn't working properly, but troubleshooting the problem can be relatively easy if you know what to look for. Here are some common issues you might encounter and how to fix them:
Low Water Pressure
If you're experiencing low water pressure, the first thing to check is your water supply. Make sure the tap you're using is fully open, and check that your water hose isn't kinked or blocked. If your water supply is fine, the problem could be with your water pump. Check that it's switched on and that the pump strainer isn't blocked with debris.
No Water Flow
If you turn on the tap and nothing comes out, there could be a few different issues at play. First, check that your water tank isn't empty. If it is, refill it and try again. If your tank is full, the problem could be with your water pump. Check that it's switched on and that the pump strainer isn't blocked with debris. If your pump is working fine, the issue could be with a blocked tap or a blocked water filter.
Contaminated Water
If you notice that your water has an unusual taste or smell, or if you see discolouration or particles in your water, it could be contaminated. This could be due to algae, fungi, or other contaminants in your water supply. The first step is to test your water to determine what's causing the contamination. If the problem is with your water supply, you may need to switch to a different source. If the issue is with your water tank or pipes, you'll need to clean and disinfect your water system.
Water Heater Issues
If you're having problems with your caravan's water heater, the first thing to check is the power supply. Make sure your heater is plugged in and that the circuit breaker hasn't tripped. If your power supply is fine, the issue could be with the heating element or thermostat. Check these components and replace them if necessary. If your water heater is working fine but your water is still cold, the problem could be with your hot water system. Check that your hot water tap is fully open and that your hot water pipes aren't blocked.
Water Testing
Regular water testing is an essential part of maintaining your caravan's water system. This will help you identify any potential issues before they become major problems. You can buy water testing kits online or from camping stores. These kits will test for a range of contaminants, including bacteria, nitrates, and pH levels. If you identify any issues, you'll need to take steps to address them, such as cleaning your water tank or disinfecting your pipes.
By following these troubleshooting tips, you can keep your caravan's water system working properly and ensure that you always have access to clean, safe water.

Help:RedirectsEdit This Page
From FamilySearch Wiki
Quick Reference: To redirect, type _TAG_ [[pagename]] inserting the redirect destination where the word "pagename" appears.
Redirects are used to forward users from one page name to another. They can be useful if a particular article is referred to by multiple names, or has alternative punctuation, capitalization or spellings. Redirecting pages may also be helpful when joining two pages into one, or if two articles contain the same, or similar information.
To redirect, or not to redirect
Before creating a redirect, first decide which of the following you are trying to accomplish:
1. Are you trying to help users find the same article under various names? This may be accomplished by creating a new page by a new title, and redirecting that page to a pre-existing page. If you are simply trying to rename a page, however, please see Renaming a page for details.
2. Are you trying to send users from a pre-existing page to another pre-existing page? If so, please see the heading "Resolving duplicate articles" below.
3. Are you trying to send users from a pre-existing page to a page that has not yet been created?
Once you know which of the following you are trying to accomplish, decide which page you want to redirect FROM, and which page you want to redirect TO. You may want to copy the page titles of both exactly as they appear in the Wiki. Make sure both pages exist before redirecting one page to another. Learn how to create a new page. Once both pages exist (whether text appears in those pages or not), please follow the corresponding instructions below.
Resolving duplicate articles
Duplicate pages may be resolved by copying differing information from one of the articles into the other article, and then re-directing the first article to the second article. Pages and articles are often linked together. By re-directing pages, the links to various pages will not be broken. For example:
- Article A contains similar information to Article B.
- Copy any differing information from Article A into Article B.
- After copying the information from Article A, confirm that it all appears in Article B.
- Remove any remaining text from Article A, however, do not "Delete" the page (NOTE: Deleting pages may only be done by users with administrative roles). Removing text from one of the articles is not mandatory, however, it is a good best practice. The removed text is not gone forever, but remains in the history of that page in case at some point the redirect needs to be removed.
- Using the steps below, create a "Redirect" FROM Article A TO Article B.
Creating a redirect
1. Make sure you are logged in.
2. Locate and navigate to the page you want to redirect FROM.
3. Click "Edit" under the page options. This should open the Editing window.
4. In the Editing window, type the following, however, instead of the word "pagename" type the identical title of the page you want to direct TO:
5. Before saving, you can use the 'preview' button, to check that you have entered the correct page name (Generally you will be redirecting to an existing page name, so the link should be blue, not red). If the pagename appears red, the title entered was incorrect. (NOTE: Pagename titles are case sensitive. For example, if you attempt to redirect a page to the article titled "Indiana birth records," and you type "Indiana Birth Records," the redirect will not work.)
6. Remember to save your changes by clicking the "Save page" button located below the Editing window.
Accessing a redirected page
After creating a redirect, you will be unable to access the page that you redirected FROM by searching for the title. Any time a user tries to access that page, they will automatically be redirected to the page you indicated in the redirect, however near the top of the page, a link is provided that will allow users to return to the page you redirected FROM. Click this to view the page you redirected FROM.
By doing this, you can do all the things that any other wiki page allows. You can go to the associated discussion page to discuss the redirect. You can view the history of the page before the redirect was put in place. You can edit the page if the redirect is incorrect, and you can revert to an older version to remove the redirect.
Deleting a redirected page
Deleting a redirected page is different from removing a redirect from a page. There is generally no need to delete redirected pages. They do not occupy a significant amount of database space, and they do not show up in wiki search results. If a page name is vaguely meaningful there's no harm (and some benefit) in having it as a redirect to the most relevant existing page in your wiki. However...
If you do need to delete a redirect, e.g. if the page name of the redirect is offensive, or you wish to discourage people from referring to a concept by that name, then you simply go to the redirect page, and follow the same procedure for deleting a page. See: Deletion Requests
A double redirect (a page redirecting to a page which is itself a redirect) will not work. The redirecting will not follow through to the end of the chain. Instead people will just be presented with the relevant link (a view of the redirect page). This is a deliberate restriction, partly to prevent infinite loops, and partly to keep things simple. It avoids people building up an unpleasantly complicated tree of redirects!
However this does mean that you should look out for double redirects and eliminate them, by changing them to be 1-step redirects instead. You are most likely to need to do this after a significant page move. Use the 'what links here' toolbox link to find double redirects to a particular page, or use Special:DoubleRedirects to find them throughout the whole wiki.
A redirect to a page in the category namespace
To prevent a page that redirects to a category from appearing in that category; precede the word Category with a colon like so : _TAG_ [[:Category:Glossary]]

I collect data from a battery powered light sensor.
To maximize battery life, the device only sends data when there is a change in the light level instead of on a regular schedule. If the light level is constant, for example during the middle of a cloudy day, then it may not send any data for an hour or more.
If I have a plot that is only looking at the last 30 minutes then sometimes Grafana shows nothing because no data has been received in that 30 minute window, whereas in reality the current light level can be inferred by looking at the last reported value, even if that value was received hours ago.
Does Grafana have a way of displaying the current inferred value using the last known value even if it's outside the current window?
As far as I can tell the only alternative is to write a program that sits in between the sensor and Grafana that remembers the last received value and periodically generates fake data points. This wastes storage space and makes Grafana slower.

Should You Buy ENI S.p.A. (NYSE: E) At This P/E Multiple?
ENI S.p.A. (NYSE: E) trades at a P/E multiple of 16.7x, which is lower than the Energy sector median of 17.1x. While this makes E appear like a stock to add to your portfolio, you might change your mind after gaining a better understanding of the assumptions behind the P/E ratio. In this article, I will break down what the P/E ratio is, how to interpret it and what to watch out for.
Understanding Valuation Multiples and the P/E Ratio
A multiples valuation, also known as a comparable companies analysis, determines the value of a subject company by benchmarking the subject's financial performance against similar public companies (peer group). We can infer if a company is undervalued or overvalued relative to its peers by comparing metrics like growth, profit margin, and valuation multiples.
P/E Multiple = Stock Price ÷ Earnings Per Share
The P/E ratio is not meant to be viewed in isolation and is only useful when comparing it to other similar companies. Since it is expected that similar companies have similar P/E ratios, we can come to some conclusions about the stock if the ratios are different. I compare ENI S.p.A.'s P/E multiple to those of TOTAL S.A. (NYSE: TOT), Statoil ASA (NYSE: EQNR), BP p.l.c.(NYSE: BP) and Royal Dutch Shell plc (NYSE: RDS.B) in the chart below.
E P/E Ratio vs Peers Chartsource: Benchmarks: P/E Multiples
Since ENI S.p.A.'s P/E of 16.7x is lower than the median of its peers (19.8x), it means that investors are paying less than they should for each dollar of E's earnings. As such, our analysis shows that E represents an undervalued stock. In fact,'s P/E Multiple Modelcalculates a fair value of roughly $48.50 per share which implies approximately 31.0% upside.
E P/E Valuation Calculation
Note that the selected multiple of 21.9x in the analysis above was determined by averaging ENI S.p.A.'s current P/E multiple with its peer group.
Understanding the P/E Ratio's Limitations
Before jumping to the conclusion that ENI S.p.A. should be added to your portfolio, it is important to understand that our conclusion rests on two important assumptions.
(1) the selected peer group actually contains companies that truly are similar to ENI S.p.A., and
If the first assumption is not accurate, the difference in P/E ratios could be due to a variety of factors. For example, if you accidentally compare ENI S.p.A. with higher growth companies, then its P/E multiple would naturally be lower than its peers since investors reward high growth stocks with a higher price.
E Net Income Growth and Margins vs Peers Tablesource: P/E model
Now if the second assumption does not hold true, ENI S.p.A.'s lower multiple may be because firms in our peer group are being overvalued by the market.
What This Means For Investors
As a shareholder, you may have already conducted fundamental analysis on the stock so its current undervaluation could signal a potential buying opportunity to increase your position in E. However, keep in mind the limitations of the P/E ratio when making investment decisions. There are a variety of other fundamental factors that I have not taken into consideration in this article. If you have not done so already, I highly recommend that you complete your research on ENI S.p.A. by taking a look at the following:
Valuation Metrics: what is ENI S.p.A.'s free cash flow yield and how does it compare to its publicly traded peers? This metric measures the amount of free cash flow for each dollar of equity (market capitalization). Analyze the free cash flow yield here.
Risk Metrics: what is ENI S.p.A.'s cash ratio which is used to assess a company's short-term liquidity. View the company's cash ratio here.
Efficiency Metrics: return on equity is used to measure the return that a firm generates on the book value of common equity. View ENI S.p.A.'s return on equity here.

Section Access: Circular References Are (Maybe) OK!
I want to share an accidental discovery that will likely change the way you implement QlikView Section Access forever—it certainly did for us and our clients!
There is a simple principle in QlikView that even novice developers know: circular references are to be avoided like the black plague. Because of QlikView's unique associative data model architecture, circular references are strictly forbidden. In fact, QlikView itself will break any circular references it finds by turning one or more table links into "loosely coupled" links.

A circular reference occurs whenever it is possible to get from one table in the data model to another through more than one path. In the picture above, for example, you can get from Budget to Orders either directly (using ProductID as a key field) or through Customers. This results in a "circular" reference (and the word circular is also an apt description, since you can see that a "circle" is formed with the table links).

The important discovery that I want to share in this article is that circular references in QlikView are not a problem when Section Access tables are involved! Suppose you have a structure as follows, where the Section Access table is indicated by the dotted border. This is a pretty common Section Access use case, where a user has access to one or more geographic regions:

Now suppose that you also want to add a restriction on the user to allow him to see only online sales (as indicated by the #ONLINESALEFLAG in the Fact table). Many developers would, when faced with this problem, created a composite-key link between the FACT and GEOGRAPHY tables. And, indeed, this is generally considered a perfectly acceptable solution to this problem. The composite key would use both TerritoryID and #ONLINESALEFLAG, and might looks something like: "TERRITORY1|ONLINE". The GEOGRAPHY dimension would then double in size to create a match for all the #ONLINESALEFLAG permutations, and the section access table would link to a REGIONID/#ONLINESALEFLAG composite.

Imagine trying to implement something like that if you have more than 2 possible values, however! Suppose #ONLINESALEFLAG had 5 possible values; restricting your data model to a single table would quickly cause the size of that table to spiral out of control. Fortunately, you may not have to! As it turns out, the following data structure often works just fine:

For whatever reason, QlikView does not have a problem with circular references caused by section access tables (where the section access tables complete the "circle"). This, clearly, opens up a world of possibility when designing your data model for security. Essentially, you might now have total freedom to structure your section access to dynamically restrict users to any numbers of fields in your data model, even if those fields are in different tables!

Update, based on valuable input from the legendary Henric Cronström (see below): Use caution when implementing this technique with multiple fields. QlikView actually will loosely couple the section access tables behind the scenes, it will just not warn you that that is what it is doing. As a result of loose coupling, you cannot specify "AND" logic for multiple field reductions for those fields affected by the loose coupling. So, in my example above, you cannot grant a user access to Online-only sales for Region1 and Non-Online-Only sales for Region2. Rather, the result will be that the user will have access to (Online or Non-Online) and (Region1 or Region). The distinct values of each field will be evaluated separately, rather than together. This may be the result that you want, but it is not likely. The solution described in this article is, therefore, not likely a good fit if a user has more than a single record in the section access tables.

Note also that, for best performance and to ensure predictable results, synthetic keys still be avoided. Meaning, a section access table should not link to 2 fields within the same table. Note also that this example demonstrates a side lesson as well—that section access tables can be linked just like regular (i.e. section application) QlikView tables. In this case, we have 2 section access tables that are linked on the field NTNAME. This field will, in turn, be automatically linked by the system to the logged-on username of QlikView users.

 Very neat Vlad! I'll try this out for sure.
 I'm guessing we can add more than one column in the second Section Access table alongwith the #ONLINESALEFLAG. Say there's a ProductLine that needs Section Access as well. Then PRODUCTID could be added on to this table as well. Will have to check with some data how multiple Section Access columns get resolved.
 2. Jasleen, you can definitely add more than one column. However, as I mentioned in the article, watch out for synthetic keys. Those are problematic even in Section Access. I ran an experiment and found that adding synthetic keys significantly slowed down application opening time. Of course, each app is different, but keep this in mind.

 Vlad

 Be careful here… Yes it will work, but it will not always do what you want. An example: If you have a user that is allowed to see product X in Germany and product Y in France, you might create an authorization table like
 User Product Country
 A X DE
 A Y FR
 This will reduce data, but not the way you want it to. You want to see transactions fulfilling
 (Product='X' AND Country='DE') OR (Product='Y' AND Country='FR')
 but you will get
 (Product='X' OR Product='Y') AND (Country='DE' OR Country='FR')
 HIC
 4. Thanks for that correction. On further testing, it turns out that QlikView DOES loosely couple the section access tables behind the scenes, it just doesn't warn you that that's what it is doing! Interesting, since you will get notified about synthetic keys caused by section access, so I'm not sure why it won't warn you for a circular reference. For the scenario that I tested at my own clients, this wasn't a problem. But your advice to use this cautiously is absolutely correct.
 Regards,
 Vlad
 5. Henric, I've just updated the article to reflect your cautionary advice. Thanks again!
 Vlad
 6. HIC says:
 It is really not loosely coupled either. It is rather that QlikView makes "implicit selections" before it opens the document – it first makes a selection in the first field (e.g. Product is X or Y) and then in the second field (e.g. Country is DE or FR). Finally it reduces the data before it displays the app to the user.
 So it is in fact "loyal" to the selection principles used in normal situations: OR between values within a field, and AND between different fields.
 HIC
 7. Vlad Gutkovsky says:
 Henric, I ran a test where I loaded the section access table as a regular section application table (so it became loosely coupled), and it behaved the same as you are describing. So maybe that's what loosely coupling does? I've uploaded the example here: _URL_

 Hi Vlad
 I have a strict requirement with my application for row level access for set of users.
 A user will have a set of records(recordid) he has access to on Table A & Table B and the second user has access to same or different set of records on Table A, B & C.
 In my application i might have as much as 10+ contatenated into fact table and another 5-8 dimension tables.
 I am trying to cover the security to be implemented @ every row on every table.
 When i implement the section access there are a lot of synthetic keys & circular references.
 Any inputs/ideas on handling this situation.
 Appreciate any guidance
 Thanks
 aravind
 9. Aravind,
 I'm not sure how Tables A – C are connected in your data model, so my answer will need to be somewhat general. First, if a particular user does not have a reduction value on a particular field, it's perfectly acceptable to leave it null. A null value in Section Access will mean that the user won't have reductions on that field at all (as opposed to a '*', which does something else).
 Second, as mentioned above regarding synthetic keys, I would suggest that you avoid these in Section Access. My testing has shown that they work, but significantly hurt performance. If you truly need to reduce on 2 fields in the same table, concatenate those fields together and use the single field as a reduction field.
 Third, regarding circular references, that is what this entire article is about, so can you be more specific?
 Regards,
 Vlad

In law, a concurring opinion is in certain legal systems a written opinion by one or more judges of a court which agrees with the decision made by the majority of the court, but states different (or additional) reasons as the basis for his or her decision. When no absolute majority of the court can agree on the basis for deciding the case, the decision of the court may be contained in a number of concurring opinions, and the concurring opinion joined by the greatest number of judges is referred to as the plurality opinion.
As a practical matter, concurring opinions are slightly less useful to lawyers than majority opinions. Having failed to receive a majority of the court's votes, concurring opinions are not binding precedent and cannot be cited as such. But concurring opinions can sometimes be cited as a form of persuasive precedent (assuming the point of law is one on which there is no binding precedent already in effect). The conflict in views between a majority opinion and a concurring opinion can assist a lawyer in understanding the points of law articulated in the majority opinion. Occasionally, a judge will use a concurring opinion to signal that he or she is open to certain types of test cases that would facilitate the development of a new legal rule, and in turn, such a concurring opinion may become more famous than the majority opinion in the same case. A well-known example of this phenomenon is Escola v. Coca-Cola Bottling Co. (1944).
Concurring opinions may be held by courts but not expressed: in many legal systems the court "speaks with one voice" and thus any concurring or dissenting opinions are not reported.
Types of concurring opinionsEdit
There are several kinds of concurring opinion. A simple concurring opinion arises when a judge joins the decision of the court but has something to add. Concurring in judgment means that the judge agrees with the majority decision (the case's ultimate outcome in terms of who wins and who loses) but not with the reasoning of the majority opinion (why one side wins and the other loses).
Concurring opinions by regionEdit
In some courts, such as the Supreme Court of the United States, the majority opinion may be broken down into numbered or lettered parts, and then concurring justices may state that they join some parts of the majority opinion, but not others, for the reasons given in their concurring opinion. In other courts, such as the Supreme Court of California, the same justice may write a majority opinion and a separate concurring opinion to express additional reasons in support of the judgment (which are joined only by a minority).
In some jurisdictions (e.g., California), the term may be abbreviated in certain contexts to conc. opn.
Terminology at the various courtsEdit
- At the International Court of Justice, the term "separate opinion" is used and judges can also add declarations to the judgment.
- The term concurring opinion is used at the Supreme Court of the United States.
- The European Court of Human Rights uses the term concurring opinion and calls both concurring and dissenting opinions separate opinions. Judges very rarely add declarations to the judgment.
- Historically the Law Lords of the United Kingdom gave each an opinion of their own and no aggregated judgment was provided. However, the new Supreme Court of the United Kingdom allows for such aggregated judgements, and it is theoretically possible for such concurring opinions to now arise.
Notable concurring opinionsEdit
- Whitney v. California (1927), Justice Louis Brandeis+1, free speech, became precedent 50 years later in Brandenburg v. Ohio.
- Escola v. Coca-Cola Bottling Co. (1944), Justice Roger Traynor, strict liability for manufacturers, became precedent 19 years later in Greenman v. Yuba Power.
- Youngstown Sheet & Tube Co. v. Sawyer (1952), Justice Robert H. Jackson, definitive test for the limits of Presidential power.
- See, e.g., McConnell v. Federal Election Commission, 540 U.S. 93 (2003).
- See, e.g., Cheong v. Antablin, 16 Cal. 4th 1063 (1997). Justice Ming Chin's concurrence began with these words: "Obviously, I concur in the majority opinion I have authored. I write separately to state another reason to reject plaintiff's argument."
- According to Professor Frédéric Rolin, ECHR judges added declarations in only two cases: Papon v. France (25 July 2002) and Martinie v. France (12 April 2006) ("Note sous CEDH 12 avril 2006, Martinie c/ France", 18 April 2006 Archived 7 February 2009 at the Wayback Machine)

E-Navigation – a tool for safe navigation
E-Navigation is one of the tasks within the EfficienSea project. The E-Navigation scheme aims to create an integrated intelligent navigation system that provides navigators with the essential information that they need – and only that.
Better collection and exchange of information
The aim of E-Navigation is to create a tool that can collect, optimise and sort the information. Today there are many medium and large quantities of information on the bridge. E-Navigation will put all this into a system that shows only the relevant information for each ship, and automatically generates the administrative information that the ship has to send to the authorities or suchlike.
Increased safety, locally and globally
As a result, E-Navigation is a tool that improves navigation safety both in our own waters and around the world.


Omega TK 2.5.2
New features
 - The fragment library is now shared across multiple instances of the OEOmega objects in a thread-safe manner. This can greatly reduce the amount of memory needed to run a multi-threaded version of Omega TK. For example, the memory consumption of Omega TK running across 8-cores dropped from 715MB to 258MB for 14,000 lead-like compounds from MDDR. This can also lead to a performance improvement since expensive fragment generation can sometimes be avoided if it has already been completed by another thread.
 - The internal fragment library for the Omega TK shared library is now stored in a more space and time efficient manner. Creating an OEOmega object and running it on a single molecule should now be faster. For example, running the example on a single benzene now takes 0.25 seconds instead of 0.83 seconds. Your mileage may vary depending upon operating system and hardware.
 - The python global interpreter lock will now be released when entering OMEGA toolkit calls.
Minor bug fixes
 - Now OEOmega.operator() will fail nicely and return false for non-3D input if SetFromCT is set to false.
 - All ring bonds will be left unset by OEFlipper unless forceFlip=true.


Tau protein test
Tau protein test
A tau protein test is used to confirm whether cerebrospinal fluid (CSF) is leaking from the brain.
CSF is a colourless fluid that surrounds and protects the brain and spinal cord.
Following a severe head injury, such as a skull fracture, the membranes that cover your brain and spine could tear. If this happens, CSF can leak out of the tear, causing a watery discharge from your ear or nose.
As tau protein is only found in CSF, testing for it will help rule out other fluids, such as nasal secretions and other bodily fluids.

Investigating Motivations and Expectations of Asking a Question in Social Q&A
Social Q&A (SQA) has rapidly grown in popularity, impacting people's information seeking behaviors. Although previous research has examined how people seek and share information within SQA, fundamental questions of user motivations and expectations for information seeking remain. This paper applies the theoretical framework of uses and gratification theory to investigate the motivations for SQA use, and adapts relevance criteria from library and information science (LIS) literature to investigate expectations with regard to evaluation of content within SQA site Yahoo! Answers. A total of 75 Yahoo! Answers users participated in a survey that asked them about reasons, methods, and expectations relating to asking questions within the SQA site. Findings indicate the importance of motivations and expectations in fulfilling both cognitive and socio–affective needs based upon the type of task performed. These findings provide encouraging evidence that understanding the interrelationship between the motivations behind and expectations of asking a question can inform a more holistic framework to assess information.

specify with or without rigid base) Indicates a frame with a rigid base having an F dimension larger than that of the same frame without the suffix H. For example, combination 56H base motors have mounting holes for NEMA 56 and NEMA 143-5T and a standard NEMA 56 shaft NEMA C face, threaded shaft pump motor Close-coupled pump motor with specific dimensions and bearings Close-coupled pump motor with specific dimensions and bearings 63/4" flange (oil burner) 71/4" flange (oil burner) Integral horsepower NEMA standard shaft dimensions if no additional letters follow the "T" or "TS". Motor with NEMA standard "short shaft" for beltdriven loads. Non-NEMA standard mount; a drawing is required to be sure of dimensions. Can indicate a special base, face or flange. Non-NEMA standard shaft; a drawing is required to be sure of dimensions.
Frame Prefixes Letters or numbers appearing in front of the NEMA frame number are those of the manufacturer. They have no NEMA frame significance. The significance from one manufacturer to another will vary. For example, the letter in front of LEESON's frame number, L56, indicates the overall length of the motor.
Mounting Unless specified otherwise, motors can be mounted in any position or any angle. However, unless a drip cover is used for shaft-up or shaft-down applications, drip proof motors must be mounted in the horizontal or sidewall position to meet the enclosure definition. Mount motor securely to the mounting base of equipment or to a rigid, flat surface, preferably metallic.

Types of Mounts
Rigid base is bolted, welded, or cast on main frame and allows motor to be rigidly mounted on equipment. Resilient base has isolation or resilient rings between motor mounting hubs and base to absorb vibrations and noise. A conductor is imbedded in the ring to complete the circuit for grounding purposes.
NEMA C face mount is a machined face with a pilot on the shaft end which allows direct mounting with the pump or other direct coupled equipment. Bolts pass through mounted part to threaded hole in the motor face.
NEMA D flange mount is a machined flange with rabbet for mountings. Bolts pass through motor flange to a threaded hole in the mounted part. NEMA C face motors are by far the most popular and most readily available. NEMA D flange kits are stocked by some manufacturers, including LEESON. Type M or N mount has special flange for direct attachment to fuel atomizing pump on an oil burner. In recent years, this type of mounting has become widely used on auger drives in poultry feeders.
Extended through-bolt motors have bolts protruding from the front or rear of the motor by which it is mounted. This is usually used on small direct drive fans or blowers.

Motor Guidelines for Belted Applications The information contained in this document is intended to be used for applications where LEESON Electric and Lincoln Motors motors are connected to other equipment through the use of a V-belt drive.These are to be used as guidelines only since LEESON Electric and Lincoln Motors does not warrant the complete drive system. The goal of any belted system is to efficiently transmit the required torque while minimizing the loads on the bearings and shafts of the motor and driven equipment. This can be accomplished by following these four basic guidelines: 1. 2. 3. 4.
Use the largest practical sheave diameter. Use the fewest number of belts possible. Keep sheaves as close as possible to support bearings. Tension the belts to the lowest tension that will still transmit the required torque without slipping.
1. Sheave Diameter Guidelines In general, smaller sheaves produce greater shaft stress and shaft deflection due to increased belt tension. See Table 1 for minimum recommended sheave diameters. Using larger sheaves increases the contact with belts which reduces the number of belts required. It also increases the belt speed, resulting in higher system efficiencies. When selecting sheaves, do not exceed the manufacturerâ€™s recommended maximum rim speed. Typically 6,500 feet per minute for cast iron sheaves, 8,000 feet per minute for ductile iron and 10,000 feet per minute for steel. The following formula will determine sheave rim speed: Shaft RPM x 3.14 x Sheave Dia. in inches 12
2. Number of Belts In general, use the fewest number of belts that will transmit the required torque without slipping. See Table 1 for maximum recommended number of belts. Each belt adds to the tension in the system which increases load on the shafts and bearings. Belts are most efficient when operated at or near their rated horsepower. If the sheaves have more grooves than the number of belts required, use the grooves closest to the motor.

3. Sheave Location Install sheaves as close to the housings as possible to increase the bearing life of the motor and driven equipment. AVOID
AVOID

DESIRED
4. Belt Tension In general, belt tensions are to be kept as loose as possible while still transmitting the required torque without slipping. Belt tensions must be measured with a belt tension gage. These inexpensive gages may be obtained through belt manufacturers, or distributors. Proper belt tension is determined by measuring the required force to deflect the center of the belt at a given distance. See Fig. 3. The proper deflection (in inches) is determined by dividing the belt span in inches by 64. Calculate the proper deflection and then see Table 1 for the required belt deflected force to achieve the calculated deflection. After tensioning the belt, rotate the sheaves for several rotations or start the system and run for a few minutes if possible to seat belts into the grooves, then re-tension the belts. Belt tensioning by feel is NOT acceptable. Tensioning by â€œfeelâ€? can be very misleading, and can damage equipment. New belts will stretch during use, and should be retensioned after the first eight hours of use.

Planar optical waveguides on p-type Si wafers have been fabricated by a photo-induced deposition process. Silicon oxynitride was deposited using a gaseous mixture of SiH4 (2% in Ar), NH3 and N2O under 253.7 nm UV radiation. The oxynitride composition was varied by changing N2O: (N2O + NH3) ratio while keeping N2O + NH3 and SiH4 flow rates constant. The refractive index varied from 1.46 to 1.95. The optical energy gap increased from 4.8 to 5.7 as the flow rate ratio varied from 0 to 0.25. Si-N bond shifts to higher energy owing to the incorporation of oxygen. A planar waveguide structure was fabricated using thermally grown SiO2 buffer layer of 1.1 μm thickness. The loss was estimated to be 1.1 dB/cm for TE0 mode at 632.8nm. The accuracy of measurements is 0.02 dB/cm.

As I know, there is no difference in meaning between the following two sentences.
 1. It is not important for you to eat good food.
 2. It is not important that you eat good food.
But I believe that there is a little difference between the two sentences at least because the letters in them are different.
Does anybody know the difference?
share|improve this question
It's more than the letters that's different. Do some research online and tell us what fun you had. Homework is a must. – Kris May 30 '13 at 6:11
I just want to remind OP in your about-me: "I am a English teacher in Korea..." As an English teacher, maybe, you'd better be more careful of grammar than other people. – Stan May 30 '13 at 13:21

The first sentence specifically implies that eating good food is not important for you. This means there is someone for whom it is important that you eat food. That "someone" might be the person who is telling you this thing.
In the second sentence the specific reference is not provided to whom it is not important that you eat good food i.e. it simply means that it is for sure not important to anyone that you eat good food. Consider this sentence-It is important that we have better medical facilities in our country. This means it is important for all and not specifically for anyone.
share|improve this answer
Out of context the sentences can mean the same but are partially ambiguous. Do you currently eat good food or not? This is not clear. But whichever is true, eating good food is unimportant.
However, only the second sentence allows a second interpretation, namely:
 - You currently eat good food, but the fact that you do is unimportant.
A statement with this meaning might continue:
 - It is not important that you eat good food; it is important you were born of the right parents.

Of the many comfort foods available, chocolate is identified as being the most craved, tellingly expressed by the coinage of such terms as "chocolate addiction" or "chocoholic." It has become a fetishized commodity in the United States that people associate with reward, comfort, luxury and sensuality. "Chocolate consumption" is an appropriately ambiguous phrase for it may refer to either the purchasing or the eating of chocolate. The unresolved tension of this ambiguity draws forth the latent connotation of "consumption" where both meanings are combined – consumption is the act by which a consumer merges with a commodity. It is this deeper significance and its close relationship to the Marxist phenomenon of fetishism that I will explore. This paper seeks to answer the question, "How is chocolate an example of a fetishized commodity in 21st century U.S. society?" My study will touch upon the overall structural and supportive role of fetishism within the capitalist system, but primarily aims to clarify the exact mechanism by which the consumer class is successfully manipulated by it. I argue that chocolate marketing exemplifies the way a commodity's fetish status may be created and intensified through the promise of an object's capacity to transform the consumer's deepest aspects of his or her self.

Just 36 miles from downtown San Francisco is the charming and historic waterfront town of Benicia. The combination of a vibrant art scene, historical landmarks, and excellent dining choices make this a place that can be enjoyed by one and all.
As well as learning about the local history, there are plenty of opportunities for shopping, both in big shopping outlets and smaller specialty ones. As of 1987, Benicia has been part of the California Main Street program and is a trendy day trip out of San Francisco.
Benicia has a long and fascinating past and has, over the years, played an essential role in California's history. For a short period in the mid 19th century, the town became the state capital. In 1853, the original capitol building was erected in the historical landmark and tourist attraction of Benicia Capitol State Historic Park.
Many of California's most meaningful events affected Benicia, including the original Mexican culture, the gold rush, the Transcontinental Railroad, and the Civil War.
One of the great things about Benicia is that the majority of the town can be explored on foot. The only landmarks that are slightly too far out are the Arsenal building and the Camel Museum. Benicia's downtown area adjacent to the waterfront promenade is ideal for strolling and taking in the sights.
A great first place to stop is the Visitor Information office on Main Street, 90 First Street, Benicia. There are plenty of brochures and maps available to help all visitors enjoy the town to the maximum. Information regarding the Historic Downtown Benicia Walking Tour can be found at the visitor center.
The tour features 25 locations, all with proximity to one another, such as The Union Hotel, the Pony Express Shop, and St Pauls Episcopal Church.
Things To Do in Benicia
Benicia Fire Museum
The Fire Museum is an exciting experience. It is home to one of the first fire engines seen in the state and various equipment and artifacts from the 1800s. The museum is located at 900 East Second Street, Benicia.
2. Fischer-Hanlon House offers an extravagant Victorian garden and is a beautiful example of a middle-class home towards the 19th century. It was home to the same family for 110 years before being donated to the state in 1968. It's open on Sundays, and guided tours are available on each month's first and third Sundays. 115 West G Street Benicia.
Benicia Historical Museum and Camel Barn
The Historical Museum and Camel Barn is the ideal place to get a grip on Benicia's history and that of the US Army Arsenal. The museum is open from Wednesday to Sunday. 2060 Camel Road Benicia
The Waterfront is gorgeous and offers some incredible views over the bay. It is the former location of the ferry terminal and shipyards but is now the First Street Promenade.
Benicia Capitol State Historic Park
The main attraction is the old capitol building. It is a unique white-columned construction that was crafted from materials of salvaged ships. It is open Thursdays from 12-4 and Friday to Sunday. And 5 pm.
The quiet atmosphere Benicia combined with the spectacular scenery meant that by the mid-1900s, the town was somewhat of a hub for the San Francisco art scene.
It continues to be a popular place for the arts and artists, and there is now a charming mix of cultures. The bohemian vibes come through now only in the galleries but also in the dining and shopping opportunities.
There are plenty of boutique stores and excellent eateries. Many of the best shops in Benicia are found on First Street and the nearby area. For a superb selection of art, exhibitions head to the shared space at The Arsenal.
Benicia Events to look out for:
Farmers Market – For fresh produce, arts and crafts, and pony rides. They are held on Thursday evenings from April until October.
Torchlight Parade – Features music, dancing, and live entertainment and is held on July 3rd and 4th on First Street. Artists Open Studios Weekends – Offers the chance for local artisans and galleries to display their work on the first weekend in December and the one before Mother's Day.
Yacht Races and Opening Day on The Straits – Decorated float parades held on the third Saturday in April. More information about this day trip can be found here.
