text: In VLSI CAD, difficult optimization problems have to be solved on a constant basis. Various optimization techniques have been proposed in the past. While some of these methods have been shown to work well in applications and have become somewhat established over the years, other techniques have been ignored. Recently, there has been a growing interest in optimization algorithms based on principles observed in nature, termed Evolutionary Algorithms (EAs). Evolutionary Algorithms in VLSI CAD presents the basic concepts of EAs, and considers the application of EAs in VLSI CAD. It is the first book to show how EAs could be used to improve IC design tools and processes. Several successful applications from different areas of circuit design, like logic synthesis, mapping and testing, are described in detail. Evolutionary Algorithms in VLSI CAD consists of two parts. The first part discusses basic principles of EAs and provides some easy-to-understand examples. Furthermore, a theoretical model for multi-objective optimization is presented. In the second part a software implementation of EAs is supplied together with detailed descriptions of several EA applications. These applications cover a wide range of VLSI CAD, and different methods for using EAs are described. Evolutionary Algorithms in VLSI CAD is intended for CAD developers and researchers as well as those working in evolutionary algorithms and techniques supporting modern design tools and processes.

This article reviews the rate of body dissatisfaction and weight bias among young children. It was initially hypothesized that body-image begins much earlier than adolescence, where most interventions take place. Out of fifty articles read on the subject, forty-five peer reviewed articles were included in this review. The findings of these articles were synthesized for a comprehensive review on the topic. Results suggested that weight bias begins around three years of age, while body dissatisfaction begins around age five for girls, and seven for boys. Rates of body dissatisfaction among children were similar to the rate among adolescents, averaging out to be 50%. Results were also similar between males and females, concluding that body dissatisfaction is similar regardless of gender. However, protective factors, such as race and ethnicity, and the absence of weight bias and misclassification in parents, often decreased the rates of body dissatisfaction. Interventions have been implemented as a means to increase body satisfaction in children and adolescents, but none have been successful. Most interventions provided an increase in knowledge for participants, but changes in behavior were not seen long term. The conclusions reached in this study include an optimal age for intervention, between three and seven, and provide information on where this dissatisfaction could stem from.

Why do you have weight restrictions?... The manufacturers of parachute equipment and the Federal Aviation Administration have set stringent requirements on the operating limits under which parachutes are designed to work. Specific testing of how parachutes are tested had how much weight they can safely support and at what speeds they are designed to open are detailed in FAA Technical Service Order (TSO) 23B, C & D. To make a very long story short a parachute system is designed for a maximum exit weight (the weight of the parachute, jumpers, and gear as they exit the plane).
Let's make an example of a tandem; the parachute itself weighs about 65 pounds, your tandem instructor might weigh 210 pounds leaving room for a student to weigh up to 225 pounds. "WAIT A MINUTE, I thought it was about 210 pounds was the limit?" Ok, you're right, let me explain more...
If we have an instructor who weighs less can they can in theory take a larger student, but, the instructor must be physically capable of controlling the student in the airplane, in freefall, under canopy and landing. We reach a point where the smaller instructor just can't safely manage the larger student.
OK, but in your example above you could take a 225 pound student. Yes, in theory that is correct, but, that is under optimal conditions.
Alright, what are those conditions? Weather, elevation above sea level where the parachute center is. Weather - On a cool day with weather in the mid 70's and a steady breeze blowing from an open and clear direction at a parachute center which is at sea level, sure, no-problem with taking a 225# student. But as air gets warmer and the higher the humidity the higher the density altitude.
Density altitude is a very straight forward term that places a value on how dense the atmosphere is. Just to use round numbers and not get too technical, if we were at an airport which was at sea level on a 95 degree day and the humidity in the 80's the density altitude might be something like 2,500 feet. What that means is that something that flies, airplanes, balloons, and yes, parachutes fly like they were actually at 2500 feet above sea lever. They are just less efficient at higher altitudes and don't work as well.
What does all that mean. Exit weight 500 pounds, 70 degrees, 20% humidity, steady 12mph winds to land into, landing area at sea level, NO PROBLEM, I would expect to be able to give you a very soft stand up landing. BUT, Exit weight 500 pounds, 90 degrees, 85% humidity, no wind, at an airport say 1500 feet above sea level, NO WAY, the possibility of a harder landing just isn't worth it.
Also each major component of a parachute has a placard on it stating it maximum suspended weight and the maximum speed the parachute components are designed to withstand.

V. Znak (Vladimir Ilich Znak) is Senior scientific researcher at The Institute of Computational Mathematics and Mathematical Geophysics, Russia. He received his Ph.D. in 1980 at The Sevastopol instrument-making institute, Sevastopol. His Research interests were in the field of signal processing, estimation of signal parameters and characteristics, computational mathematics, applied statistics, computational technologies, development of algorithms and computer programs, formal logic, etc. he is Author of more than 70 publications, including inventor's certificates.
Periodic (harmonic and frequency-modulated
– FM) signals are widely used, and an appropriate research can be of interest in different fields of activity. Our purpose is to study the above signals for estimating their parameters and characteristics such as locus of a signal on a time axis and the degree of their presence in noise. Such indications determine the degree of trust to consequent estimations. At the same time, we assume that a signal is recorded at a discrete time t1,…, tN, where ti-1 – ti =t = const, i=2,…, N.
We propose to use the cluster analysis for studying periodic signals. According to this, we consider the corresponding approach, the statement of a problem and specify the way of its decision. Finally, we intend to present some results of the data obtained of a model of the FM signa


Pakistan, China custodians of world's ancient civilizations
An exclusive interview with Social Diary Director of China Cultural Centre, Mr You Yi
By: Zubair Qureshi
Since his arrival in Islamabad less than two months ago (on September 2, 2016) Chinese Cultural Counselor Mr You Yi is already working on a number of ideas and themes to further promote cultural and people-to-people ties between China and Pakistan. A man full of ideas and deep insight Mr Yi has no ambiguity about his role as the cultural ambassador of China in Pakistan and takes pride in the fact that he is in a country that is considered the most trustworthy friend of China. Mr You Yi has earlier served as a diplomat in Finland, Canada, New York City, USA, Netherlands and Ethiopia.
In an exclusive interview, Mr You Yi candidly outlined his plans and vision to strengthen cultural ties between the two countries.
Q: How do you view relations between Pakistan and China especially in the historical perspective?
Mr You Yi: Both Pakistan and China have quite a history of good relations in various fields ranging from economic, cultural, education and industrial to education, sports and art and artists. Pakistan is in fact among the first countries to establish diplomatic relations with China and it is because of Pakistan that China opened up to the outer world. That's why we value our relations with Pakistan and consider it our great friend.
Q: Which are the untapped areas that can be addressed to further strengthen friendly ties between the two countries?
Mr You Yi: Pakistan is China's all-weather friend, a strategic partner and there are areas which have huge untapped potential for mutual cooperation like tourism, education, art and artists and cultural exchange. China and Pakistan are working on CPEC which will prove game changer in the region, however, at the same time he emphasized that besides economic corridor, cultural corridor is equally important. It will serve to win people's hearts.
Q: As cultural counselor of China in Pakistan what way forward have you put before yourself in order to promote cultural relations between China and Pakistan?
Mr You Yi: I am looking forward to working at different levels. We have a certain framework to move simultaneously in the areas of education, tourism, art and cultural exchange and women cooperation.
Q: Does your plan include exchange of youth or scholarships for Pakistani students?
Mr You Yi: The government of China is offering scholarships to the Pakistani youth and recently a batch of Pakistani students has left for Chinese universities. Besides, cultural and economic cooperation we have also room for cooperation in the fields of sports. We shall cooperate in this particular area as well. Another area is language of each other's country. Urdu is being taught at certain Chinese universities, similarly in Pakistan Chinese language is being taught, which is again a reassuring factor. It will also serve as a medium of cooperation and coordination between the two countries.
Q: Pakistan is facing a number of challenges like extremism, terrorism, poverty and militancy. What recipe will you offer to overcome them?
Mr You Yi: The government and people of China are deeply concerned about the menace of terrorism and we extend all out cooperation and assistance to curb this menace. The purpose of the CPEC and cultural cooperation is to build mutual prosperity and mutual benefit which is key to lasting peace.
Q: How can prosperity return to Pakistan?
Mr You Yi: I view political stability and economic prosperity interlinked. Unless there is political stability and things are well in place, dream of prosperity I fear will remain largely unrealized. Pakistan should take maximum advantage of China's Trade Policy. China is now the world's second largest economy and China's trade with the rest of the world reached 4 trillion US Dollars last year. In 1949, China's GDP per capita was only 35 US Dollars. Now the GDP per capita reached US$8000.
In the end, Mr You Yi said that Beijing and Islamabad have been close partners for decades, the ChinaPakistan Economic Corridor (CPEC) is a reflection of intensified and expanded bilateral cooperation at a time of rising Chinese geopolitical ambition and persistent concerns about Pakistan's security and development. Chinese Cultural Consular, You Yi ranked the Pakistan Ministry of Foreign Affairs, Ministry of Culture and other Pakistani organizations for making the celebrations of 67th Anniversary of founding of People's Republic of China (1949- 2016) a great success in Pakistan.
Committing to the World of Music IN CONVERSATION WITH RIZWAN Anwar


was zero, day 0 was defined as the previous business day at the same time.
In 6.xx, if the check fails, and $timecheck is non-zero, the behavior is the same as before. If $timecheck is zero, day 0 is defined as the next business day at the same time.
So day 0 is now always the same, where before, day 0 meant two different things depending on whether $timecheck was zero or not.
(*) Default time
In Date::Manip 5.xx, the default times for dates was handled in an inconsistent manner. In the Date::Manip::Date documentation, if you parse a date from the "Common date formats" section, in Date::Manip 5.xx, if no time was included, it defaulted to "00:00:00". If you parsed a date from the "Less common formats" section, the default time was the current time.
So running a program on Jun 5, 2009 at noon that parsed the following dates gave the following return values:
 Jun 12 => Jun 12, 2009 at 00:00:00
 next week => Jun 12, 2009 at 12:00:00
This behavior is changed and now relies on the config variable DefaultTime. If DefaultTime is "curr", the default time for any date which includes no information about the time is the current time. Otherwise, the default time is midnight.
%z format
In Date::Manip 5.xx, the %z format would give an offset in the form: -0500. Now it gives it in the form: -05:00:00
Dropped mixed style delta parsing
In Date::Manip 5.xx, a parsed delta could be written in the delta style
or in a language-specific expanded form:
 1 hour 2 minutes 3 seconds
or in a mixed form:
 1 hour 2:3
The mixed form has been dropped since I doubt that it sees much use in real life, and by dropping the mixed form, the parsing is much simpler.
Approximate date/date calculations
In Date::Manip 5.xx, the approximate delta between the two dates:
 Jan 10 1996 noon
 Jan 7 1998 noon
was +1:11:4:0:0:0:0 (or 1 year, 11 months, 4 weeks). As of Date::Manip 6.00, the delta is +2:0:-0:3:0:0:0 (or 2 years minus 3 days). Although this leads to mixed-sign deltas, it is actually how more people would think about the delta. It has the additional advantage of being MUCH easier and faster to calculate.
Approximate relationships in deltas
When printing parts of deltas in Date::Manip::5.xx, the approximate relationship of 1 year = 365.25 days was used. This is the correct value for the Julian calendar, but for the Gregorian calendar, a better value is _PHONE_, and this is used in version 6.00.
Old style formats
The formats used in the printf command are slightly different than in the old Delta_Format command.
The old formats are described in the Date::Manip::DM5 manual, and the new ones are in the Date::Manip::Delta manual.
The new formats are much more flexible and I encourage you to switch over, however at this point, the old style formats are officially supported for the Delta_Format command.
At some point, the old style formats may be deprecated (and removed at some point beyond that), but for now, they are not.
The old formats are NOT available using the printf method.
The day field meaning changed in a few recurrences
The value of the day field can refer to several different things including the day of week number (Monday=1 to Sunday=7), day of month (1-31), day of year (1-366), etc.
In Date::Manip 5.xx, it could also refer to the nth day of the week (i.e. 1 being the 1st day of the week, -1 being the last day of the week). This meaning is no longer used in 6.xx.
For example, the recurrence:
referred to the 3rd occurrence of the 4th day of the week in February.
The meaning has been changed to refer to the 3rd occurrence of day 4 (Thursday) in February. This is a much more useful type of recurrence.
As a result of this change, the related recurrence:
is invalid. Negative numbers may be used to refer to the nth day of the week, but NOT when referring to the day of week numbers.
Recurrence range now inclusive
Previously, the list of dates implied by the recurrence were on or after the start date, but before the end date.
This has been changed so that the dates may be on or before the end date.
Dropped support for a couple English recurrences
Date::Manip 5.xx claimed support for a recurrence:
 every 2nd day in June [1997]
In actuality, this recurrence is not practical to calculate. It requires a base date which might imply June 1,3,5,... in 1997 but June 2,4,6 in 1998.
In addition, the recurrence does not fit the mold for other recurrences that are an approximate distance apart. This type of recurrence has a number of closely spaced events with 11-month gaps between groups.
I no longer consider this a valid recurrence and support is now dropped for this string.
I also dropped the following for a similar reason:
 every 6th Tuesday [in 1999]
Other minor recurrence changes
Previously, ParseRecur would supply default dates if the start or end were missing. This is no longer done.
The Date::Manip module contains the same functions that Date::Manip 5.xx had (though the OO modules do all the work now). In general, the routines behave the same as before with the following exceptions:
Previously, Date_ConvTZ took 1 to 4 arguments and used the local time zone and the ConvTZ config variable to fill in missing arguments.
Now, the Date_ConvTZ function only supports a 3 argument call:
If $from is not given, it defaults to the local time zone. If $to is not given, it defaults to the local time zone.
The optional 4th argument ($errlevel) is no longer supported. If there is an error, an empty string is returned.
In Date::Manip 5.xx, it was recommended that you pass arguments to ParseDate or ParseDateDelta. This is not recommended with 6.00 since it is much more intelligent about handling the arguments, and you'll just end up parsing the date/delta twice.

Initiated by English architect Richard Norman Shaw in 1868, the style began with late medieval overtones but eventually acquired more classical detailing reflecting the reign of Queen Anne and the immense popularity of Classical architecture in 18th century England. The American version of the style, sometimes referred to as Free Classic, came to popularity after the Centennial Exposition of 1876 where two impressive English buildings in the style were admired.
- Irregular plan and massing.
- Steeply pitched roofs with an open gable end often prominent.
- Bay windows or towers.
- Small, classical details often overshadowed by the large mass of house.
- Wide variety of exterior material patterns used.
- Tall, thin chimneys.
- Windows with small panes over or around the primary pane.


Qiyue shares with you: the difference between nitrile gloves and medical latex gloves
As we all know, although the scope of nitrile gloves and latex gloves is somewhat similar, they are not the same. So what is the difference between medical nitrile gloves and medical latex gloves? Follow Qiyue editor to understand their differences.
 Latex gloves are also called rubber gloves. Latex is a natural material, derived from rubber tree sap. Natural latex is a biosynthetic product. Due to differences in tree species, geology, climate and other related conditions, its composition and colloidal structure will often appear huge difference. In the fresh latex without any substance, the rubber hydrocarbon only accounts for 20%-40% of the total, and the rest is a small amount of non-rubber components and water. Non-rubber components include proteins, lipids, sugars, and inorganic components. Some of them form a composite structure with rubber particles, and some are dissolved in whey or form non-rubber particles.
 Medical nitrile gloves are the popular name for nitrile gloves. Nitrile is a kind of rubber and is a key raw material for organic synthesis and pharmaceutical intermediates. Mainly synthesized from acrylonitrile and butadiene. Nitrile (jīng): A type of organic compound with a special odor that decomposes when exposed to acid or alkali.
 Latex gloves: Compared with nitrile gloves, the toughness and abrasion resistance are slightly inferior, but the elasticity is better. The abrasion resistance, acid and alkali resistance, and grease are slightly worse than nitrile, and the acid and alkali resistance is slightly better than nitrile. But it is not suitable for allergic skin and long-term wear.
 Nitrile gloves: The material is relatively hard, the elasticity is poor, the abrasion resistance is better, acid and alkali resistance (some nitrile gloves can not prevent acetone, strong alcohol), anti-static, and will not cause skin allergies, suitable People who are prone to allergies and wear it for a long time.

GOSHEN, Utah – Archaeologists have struck gold at a dig near the town of Goshen about 35 miles south of Provo: the largest Fremont Indian structure ever excavated.
Brigham Young University anthropology professor Jim Allison says the 850-square-foot structure is unique because it served as a communal area that brought the entire village together.
He says it has yielded "a layer of prehistoric trash" that included common items such as arrowheads, broken pottery, corn cobs and animal bones.
Allison, who oversees students' work at the site, says radiocarbon dating shows it probably was occupied between 1025 and 1100.
The Fremont Indians inhabited sites in what are now Utah, Nevada, Idaho and Colorado between 700 and 1300. They're known for pottery, figurines, moccasins and their use of farming.

A New Species of Marsupial Frog (Anura: Hylidae: Gastrotheca)
A new species of Gastrotheca from the southern end of the Cordillera Azul in Peru seems to be most closely related to G. lateollota known only from the Cordillera Huancabamba in northern Peru. Both of these species and G. marsupiata, monticola and peruana produce tadpoles, whereas the other species of Gastrotheea in Peruvian Andes have direct development.

Over time, a residential driveway can become an eyesore from leaked motor oil, tire marks and other stains. Muriatic acid, also referred to as a form of hydrochloric acid, is an extremely effective concrete cleaner -- with emphasis on "extreme." Muriatic acid, typically diluted with water, reacts with the alkalinity of the cement and "etches" the surface, dissolving surface stains and foreign material. The basic safe procedure to clean with muriatic acid is easy to follow and will help restore the appearance of your driveway's surface.
Put on all protective gear, including boots, gloves and glasses.
Mix muriatic acid with water for the desired solution, based on the manufacturer's recommendations.
Pour a small amount of the acid-water mixture carefully onto the concrete surface, beginning with a concentration on specific stained areas of the driveway. Allow the mixture to saturate the stained area for approximately 10 minutes to dissolve the material.
Scrub and spread the acid solution over the concrete surface using a floor brush. Use a wire brush on difficult stains or built-up material. Add more acid mix as needed.
Rinse the driveway thoroughly with clean water.
Repeat Steps 2 through 4 for stubborn stains or problem areas.
Things You Will Need
- Plastic bucket
- Muriatic acid
- Stiff-bristled floor brush
- Wire brush
- Rubber gloves
- Rubber boots
- Safety glasses
- Avoid rinsing the muriatic acid solution into planters or grassy areas adjacent to the driveway to prevent poisoning the plants.
- Muriatic acid is a dangerous and corrosive liquid that should be used with extreme care and only as a last resort after milder cleansers or power washing has proven ineffective. Even diluted muriatic acid will dissolve cloth or leather and presents a burn hazard for exposed skin or eyes.
- Use only a plastic bucket and dilute the acid in clean water. To prevent splashing or spillage when mixing the acid solution, add the acid liquid to the water; do not add water to the acid.

Circuit for polarity detection
 1. Can anyone suggest to me a simple circuit constructed using digital gates for polarity detection? The circuit should be able to detect positive, negative as well as zero polarity.
 I need to check the polarity of a dc motor which is controlled by a bidirectional converter. The bidirectional converter has to be controlled in current mode. If any one has ideas regarding the same, i will be grateful.
 But I am not implementing it in real time. I am trying to simulate the logic in MATLAB/Simulink. Can you suggest how I can do the same in Simulink using logic gates? or any other digital gates? The truth table is given along with the schematic for reference as to the expected binary output.
 I have attached the schematic in pdf.
 Thanks and regards

 3. You have two polarity detectors in your circuit and they are not the same. One has two outputs and the other three. Which one do you want suggestions for? What is the input range for the polarity detector? What do you want to happen if the motor is spinning in one direction and a command, Ec, is given to turn the other direction? Do you want the power to the motor to turn off and allow the motor to coast to a stop or do you want to apply a limited amount of current to the motor in the opposite direction to make it stop and reverse faster? I understand this is a simulation but sometimes simulations lead directly into real products. How will you brake the motor if you want to stop quickly? Do you care if the motor burns up if it should stall?
 Last edited: Dec 6, 2010
 4. Hi there
 i would like suggestions on both the polarity detectors. As for the input range to the polarity detector, do you mean the range within which it detects the signal as positve, negative or zero? i would like the range to be as low as possible. the motor should coast to a stop with minimum losses occurring to the motor while stalling. and the transition from one converter to another should be accompanied by a dead band / transition band during which time the polarity of Ec should remain zero. Converter 1 gets the pulses when id is positive or zero and Ec is positive. Converter 2 gets the pulses when id is negative or zero and Ec is negative.
 Thanks and regards

Are you a professional seeking to obtain or maintain a professional license, or wanting to simply clear your criminal record?
A Certificate of Rehabilitation can assist you in licensing and other matters.
While a Certificate of Rehabilitation cannot eliminate a conviction (dismiss) or remove it from your record, it acts as a positive element on your record. It also is an element of mitigation and rehabilitation in professional license defense cases and addresses certain statutory prohibitions that may prevent a person with a felony from getting hired by certain government agencies.
The Certificate of Rehabilitation can be an option for you if:
 1. You are not eligible for expungement because you had a sentence to state prison.
 2. If you are required to register as a sex offense.
 3. You want to strengthen your background after your felony conviction was expunged.
Depending on the crime, there may be waiting periods before you are able to seek a Certificate of Rehabilitation.
We will help determine the best timing for your Certificate of Rehabilitation, and we will determine the best location in which to file your petition. It may be in the county in which you live, or within the county in which the crime occurred. While the process is time-consuming and difficult, we will work with you to ensure a comprehensive and substantial packet of evidence can be submitted on your behalf.
The license defense attorneys at S J Harris Law are well equipped at painting a positive picture of you, and to highlight your mitigation and rehabilitation. This is the same type of evidence that would otherwise be necessary to defend or obtain a professional license.
All cases involving a Certificate of Rehabilitation are done on a flat fee basis and are all-inclusive through the actual legal process.
However, it is important to recognize that even after an expungement or relief in the criminal court is awarded, including a Certificate of Rehabilitation, background check companies may continue to report your conviction. When this occurs, you will need to pursue additional actions outside the expungement and rehabilitation process handled by S J Harris Law

text: Style notes: American sour ales can be very light to black or take on the color of added fruits or other ingredients. There is no Brettanomyces character in this style of beer. Woodand barrel-aged sour ales are classified elsewhere. If acidity is present it is usually in the form of lactic, acetic and other organic acids naturally developed with acidified malt in the mash or in fermentation by the use of various microorganisms including certain bacteria and yeasts. Acidic character can be a complex balance of several types of acid and characteristics of age. The evolution of natural acidity develops balanced complexity. Residual flavors that come from liquids previously aged in a barrel such as bourbon or sherry should not be present. Wood vessels may be used during the fermentation and aging process, but wood-derived flavors such as vanillin must not be present. In darker versions, roasted malt, caramel-like and chocolate-like characters should be subtle in both flavor and aroma. American sour may have evident full range of hop aroma and hop bitterness with a full range of body. Estery and fruity-ester characters are evident, sometimes moderate and sometimes intense, yet balanced. Diacetyl and sweet corn-like dimethylsulfide (DMS) should not be perceived. Chill haze, bacteria and yeast-induced haze are allowable at low to medium levels at any temperature. Fruited American-Style Sour Ales will exhibit fruit flavors in harmonious balance with other characters.

In Service Surveillance
In-service surveillance of ammunition is undertaken to ensure that ammunition
continues to meet the required quality standards throughout its entire life cycle. As explained by Mr. Adrian Wilkinson, surveillance is undertaken to ensure "that the ammunition continues to meet the required quality standards throughout its life. Quality, from this perspective, includes the performance of ammunition during use and its safety and stability during storage. The chemical, electrical, and mechanical properties of ammunition change and degrade with time, leading to a finite serviceable life for each munition. The accurate assessment of munition life is of paramount importance in terms of safety and cost."
For further explanation on the requirements for the in-service proof and surveillance of ammunition see "Stockpile Management: Surveillance and Proof" by Adrian Wilkinson in Conventional Ammunition in Surplus, Small Arms Survey, 2008,
Checklist on In Service Surveillance
The Protocol V Generic Preventive Measures checklist includes questions on in service surveillance, which are set out below.
(a) Is there an 'In Service Surveillance' procedure and organisation to assess reliability and safety during the lifecycle of munitions? For pyrotechnic parts? For electronic parts? For other parts?
(b) Is there a system in place to check that all the explosive and pyrotechnic parts within the munition remain safe and reliable?
(c) Is there a system in place to check that all the explosive and pyrotechnic parts within the fusing chain are capable of initiating the next stage as required?
(d) Is the integrity of the pyrotechnic and explosive train checked (e.g. gap between components, integrity of components …)?
(e) Is there a procedure to identify and remove degraded munitions from operational service (i.e.: regular inspection of munitions)?
(f) Is there a procedure to increase/reduce the operational lifetime of munitions?
(g) In case of an increase in the operational life time of munitions do the tests and analysis maintain confidence in the previously required level of reliability and safety?
(h) Is there an 'In Service Surveillance' procedure and organisation to record the environmental conditions that the munitions have been exposed to/ tested in?
Testing is an important component of the "development to production" phases for ammunition and the in service surveillance. Testing is the key process for verifying the reliability and safety of ammunition and determining its shelf life. This should preferably be done by live-firing.

The RA155 is a purpose-designed, military aviation headset that has been proven in several conflicts.
- Passive and active noise reduction versions
- Mask compatibility (option)
- Selection of microphone and earphone transducers
The RA155 combines communication, noise attenuation and mask compatibility with comfort. This is vitally important since noise can impair communication and cause fatigue which can lead to a reduction in crew efficiency and potentially compromise flight safety. On long flights prolonged exposure to high noise levels also poses a hazard to hearing.
RA155 is suitable for crew and operators in military transport and airborne early warning aircraft.

What Do Fresh Figs Look Like?
How do you know when fresh figs are bad?
To tell if figs are bad, the best test is the aroma.
An old or overripe fig will have a sour fermented smell.
Placing figs near other fruits and vegetables will cause the others to deteriorate more rapidly because figs, like several other fruits, produce ethylene gas..
Is there a wasp in every fig?
The female wasp crawls inside through a hole so narrow that she loses her wings in the process and becomes trapped. If the fig is a male, she lays her eggs inside. … Luckily for us, the female fig produces an enzyme that digests this wasp completely. The crunchy bits are seeds, not wasp parts.
Should figs be refrigerated?
Ripe fresh figs should be refrigerated. Because they bruise so easily, try putting them on a shallow dish, lined with paper towels. Cover the dish with plastic wrap and the figs will be good for two or three days.
What month do you pick figs?
A. Fresh figs are not tasty until soft and ripe. Therefore, pick them just as the fruit begins to soften. The fig varieties common to Texas usually ripen their fruit during July or August but because of winter freezes, fruit harvest can be delayed until new growth is forced out.
Are figs anti inflammatory?
For such small fruits, figs are an incredible source of fiber and natural sugars. The entire fruit is edible, packed with immune-boosting Vitamins A and C, potassium, calcium, and magnesium. They're also an excellent anti-inflammatory food that aids in digestion, promotes healthy skin, and balances glucose levels.
What is the season for fresh figs?
There are two seasons for domestic fresh figs; the first or "breba" season is the first few weeks in June. The second or "new wood" season typically runs from August through October. The most common variety is the Black Mission fig followed by the Brown Turkey fig and the Green Kadota fig respectivly.
Do FIGS have worms in them?
Figs Have Worms And Dead Wasps Inside Them, And The Reason Why Is Fascinating. … Case in point: figs, which are delicious and a rich source of dietary fiber. Unfortunately, you might not eat them again after watching this!
How long do fresh figs last?
It's important to keep fresh figs cold to slow deterioration. Use them immediately or store in a plastic bag in the coldest part of your refrigerator for up to two days. Fresh figs can be frozen whole, sliced, or peeled in a sealed container for ten to twelve months.
Why do figs fall off before ripe?
Lack of Water Causes Dropping Figs Drought or inconsistent watering is the most common reason that fig fruit falls off the tree. … To correct this, make sure that your fig is receiving enough water. If it's in the ground, the tree should receive at least 2 inches of water a week, either through rainfall or watering.
How do you keep figs from going bad?
Whether you choose to store dried figs in the pantry, fridge or refrigerator, it is best to put them in an airtight container or a tightly sealed plastic bag. Dried figs will last from 6 to 12 months in the pantry. It is important to keep them in a cooler area away from humidity.
What do ripe figs look like?
Fig ripeness cues include sight, touch, and taste. By sight, ripe figs tend to droop while hanging on the tree or bush, have a larger distinguishable size than the immature green fruit, and with the exception of a few varieties have a change in color. By touch, ripe figs should be soft when gently squeezed.
Why are figs not vegan?
These flowers bloom inside the unripe fig-shaped "fruit," which later ripens into the fruit that we enjoy so thoroughly. … Because of their backwards, inside-out nature, figs cannot rely on normal methods, like wind or bees, for pollination.
How many fresh figs should I eat a day?
Consuming at least three figs per day can prove beneficial for weight loss. According to a study conducted on menopausal women, the risk of breast cancer is reduced by 34 percent in women who consume fruits that are high in fiber.
Can fresh figs be frozen?
Figs freeze well with or without sugar, peeled or unpeeled. … Wash ripe figs thoroughly, remove stems, peel if desired, leave whole or cut in half. Freeze with or without sugar syrup. Freeze figs firm-ripe and whole for making preserves later.
What are the side effects of figs?
Figs may cause digestive upset or diarrhea due to their anti-constipation effects. They may also interfere with blood thinners, and some people may be allergic to them.
Are green figs poisonous?
An unripe fig fruit is not only ineffective but it can be toxic and allergic reactions may occur. … Green figs are sweeter than both brown turkey and black mission figs, making them a better choice for desserts and as a dried (candied) fig. Figs are also, of course, great for eating fresh out of hand.
Should you wash fresh figs?
How do you eat a fresh fig?
The best way to enjoy figs is raw, with the skin and seeds intact. You can also remove the peels and scoop out the seeds, if you like, or cook figs by baking, broiling or grilling them. But, the quickest and easiest way to enjoy these gems is by removing the stem and taking a bite right out of the raw fig.
When you eat a fig you eat a wasp?
Figs contain the enzyme ficin that breaks down the female exoskeleton. Well, mostly. When you eat a fig pollinated through mutualism, you are technically eating the wasp, too. But fig wasps are very small, usually only about 1.5 millimeters long.
Can I buy figs at the grocery store?
Dried figs are easy to find year around. You usually find them two ways – packaged up in a ring or available loose in a bulk bin. Stores like Whole Foods and Trader Joe's are great places to look.
Should I remove unripe figs?
Just pick off the smallest, greenest fruit, furthest away from the trunk. This will ensure that the tree sends its energy into ripening the fruit that remains. You'll end up with fewer figs, but they'll be more likely to ripen.

The well-preserved remains of almost 1,000 pile dwellings and moorland settlements can be found in numerous lakes and wetland areas in and around the Alps.
The UNESCO World Heritage property comprises a total of 111 exemplary pile dwelling sites in the Alpine regions of Austria, France, Germany, Italy, Slovenia and Switzerland. Of the sites in Germany, 15 are located in Baden-Württemberg, predominantly in the western part of Lake Constance and on Lake Federsee, and three are in Bavaria, on Lake Starnberg (Rose Island) and in Pestenacker and Unfriedshausen near Landsberg am Lech.
These ancient dwellings date back to between 5,000 and 500 BC. The boggy conditions at the sites mean that wood, textiles, plant remains and other materials have been extremely well preserved. Significant finds of fabrics, wheels, carts and logboats, many still in excellent condition, provide important information on settlement structures, trade and mobility during the Neolithic, Bronze and Iron Age.
The Lake Dwelling Museum at Unteruhldingen on Lake Constance and the Federsee Museum at Bad Buchau offer valuable insights into this fascinating subject.

The short answer is yes, but as with my most short answers, there should be a closer look to truly understand the answer.
The question above is purposely vague and so my short answer is a yes, but of course it all depends. It depends on what the expected impact is for the shrubbery. If a business were to have the expectation that a row of shrubbery around the front of the property would stop an angry customer from attacking the building…well you know the answer is no longer yes.
If the expectation is that nobody would dare walk through or hop over the shrubbery to commit a property or violent crime, then again the answer would no longer be yes.
So what good could a row of shrubbery be?
We turn to a concept first made popular in the 1970's, although it didn't take off until much later. The concept is called Crime Prevention Through Environmental Design (CPTED). This concept covers everything from designing buildings to eliminate blind spots where crimes can occur outside the view of the building tenants, all the way to…yes the placement of shrubbery.
Essentially, placing shrubbery around the perimeter of your property makes it clear to everyone where the public belongs and where they don't.
It reminds me of waste high turnstiles. Somebody once challenged our security team how a criminal could simply hop over the recently installed turnstiles. Our response was that somebody hopping over a turnstile would draw the attention of the dozens of employees sitting in view of the turnstiles. The person hopping the turnstile would have no explanation if confronted, as it would be obvious to everyone the turnstile hopping person was up to no good.
More importantly, the turnstiles were used to track badge scans, which is important information for emergencies and even investigations. So, just like the turnstiles, a row of shrubbery can be a great security investment if your intention is to set your space apart from the public's. Anybody on the wrong side of the shrubbery would clearly be trespassing and should be confronted appropriately.
The extra bonus: a row of beautifully manicured shrubbery is more pleasing for employees than a metal fence.
If you grew up in the 80's and 90's, I am sure you had your share of Stranger Danger talks from parents and schools. "Don't talk to strangers." "Don't take candy from strangers." Kids were taught to scream "Stranger Danger" when any adult male they didn't know spoke to them out in public.
Why did we have these campaigns? The answer really goes back to the 1960's when news agencies began reporting on child kidnappings. By the 1980's these stories were everywhere. I am not trying to blame the media, but let's face the fact that people develop worry and anxiety over things they see in the news because it feels like these bad things happen everywhere all the time.
Communities had to do something, and so out of love for our children, we taught them not to talk to strangers. It does seem to make sense based upon the notion that strangers are kidnapping our children all the time.
In today's world, we don't hear this message coming from our schools and community agencies any more (although I still hear parents having focused conversations with their kids about not talking to strangers). Why don't we teach this in our schools anymore, you might ask?
Because not only doesn't it work, it can be unhealthy.
First, let's think about why it doesn't work. How many times have you seen Stranger Danger tested to a parent's dismay? A parent tells his 6 year old over and over not to talk to strangers. Then the parent tests the 6 year old by having a fake "stranger" talk to them and the 6 year old walks off with the "stranger." The parent is frustrated and embarrassed at failing as a parent. Sorry parents, your kids just aren't going to be great at ignoring and avoiding strangers 100% of the time. To confuse kids more, we encourage them to talk to some strangers and not others. They see us talking to strangers. We tell them to be nice to people. Oh, but if a scary looking "dangerous" man approaches your kid, they need to scream and run away. Wait, what makes a man scary looking or dangerous? What if the man is nice? You get the point – teaching your kids not to talk to strangers is too complicated for us, let alone them.
The reality is Stranger Danger doesn't work because it does not put people and situations into context. I often talk about how context is everything. Strangers are not dangerous. People who commit violent crime are dangerous. How do we know the difference? You need context.
Speaking of context, here is some for you parents. The US Department of Justice tells us 99% of kidnappings are from known persons – not strangers. The vast majority of missing children are runaways, not victims of kidnapping. The National Center for Missing and Exploited Children does not teach Stranger Danger anymore by the way.
My second point is how Stranger Danger is actually unhealthy. There are almost just as many stories of kids avoiding rescue workers out of fear as there are stories of kids being kidnapped. That's right, the flip side of Stranger Danger is your child is so scared to talk to strangers, they don't talk to the ones who are sent to save them. Talk about adding trauma to a lost child at the amusement park. Not only would they be scared they are lost, they are scared of all those strangers just swarming around them. Further, they have nobody to turn to for help.
Do we really want our children to think strangers are bad? Do you think strangers are bad? I sure don't. Strangers not only aren't bad, they can be the people who come to our rescue in times of need. Strangers become our new friends. Strangers change our lives for the better all the time. I say strangers are good.
If you want to give your kids tools to stay safe, please first put some thought into what their actual risks are. If your only focus is on a stranger abducting your child, you are statistically focused on the least likely risk for your child. With that said, you can have rules about having to get your permission before they go anywhere with someone. Or that they have to tell you if someone asks them to keep a secret. Educate them on who to talk to when they need help – police officers, teachers, people working at a store, nurses, doctors, etc.
I know it feels like we just can't win as parents: Save our kids from kidnapping – teach them Stranger Danger. Oh no, Stranger Danger is actually bad? You just can't win.
I am not trying to make parents feel like failures. To the contrary, I want you to be more effective. Avoiding danger and violence simply needs to start with first understanding what your risks are. And I'm sorry, your view on risk will be skewed if you get your understanding from the scariest news stories of the day. To get started, try searching some trusted sites to get the facts. Put some thought into what are the actual risks, not your anxiety about risk.
I am confident once you know the risks, you will do an amazing job at giving your children the right tools to stay safe.
I believe it is essential to understand how your instincts work for 3 reasons:
 1. First, understanding your instincts helps you to TRUST your instincts
 2. Secondly, you can train yourself to AVOID INTERFERRING with your instinct process
 3. Finally, you can apply practices to AMPLIFY your instincts
There is a common expression in the Information Technology business of "garbage in, garbage out." Perhaps you have heard this expression, or even used it many times yourself. Essentially it means if the data coming into a system or process is of low quality, then it is a guarantee the output of that system or process is also going to also be of low quality.
This is also true of your instinct process. The lower the quality of information coming into our instinct process, the lower the quality of the output, which is designed to protect us. And as the author of "The Gift of Fear," Gavin de Becker writes, the instinct process always has our best interests at heart.
Obviously I am oversimplifying how our brains work, but I found this explanation serves the purpose for this topic. Just as a computer requires data input, so do our brains. We obtain real-time data input through our 5 senses. What we see, hear, smell, taste, and touch gives our brains data.
The amazing part is what our brains are able to do with that inputted data. We know our brains are phenomenal at making associations. Additionally, our brains keep tons of old data files. All of our life experiences are stored in our brain. When we intake new information, our brains begin to make associations using our past experiences. When our brains make an association that it doesn't like, such as that we are in danger of some kind, it then generates an output. It is our brain trying to influence our behavior in order to keep us safe.
Here is an example. We see a man with a gun (data input from our eyes), our brain looks at old files and determines

.NET Installer that automatically installs MSDE
By, 26 Jul 2008
Rate this:
Please Sign up or sign in to vote.
Often programmers want to build a single installer package that can install the application along with prerequisites and database. Fortunately for database, programmers can use MSDE which can be distributed along with your application, but MSDE lacks user interface so to configure it often we need to use command line.
This is the scenario:
 1. A programmer wants a single package that automatically installs.NET Framework and then installs MSDE and uses the database for the application that a programmer writes.
 2. In this tutorial, the installation will create a new database instance, with a name specified by the programmer, and it can detect whether this instance exists and as for removal, so for safety programmer just create a unique database instance name.
 3. The library then automatically attaches the database to this newly installed database instance. First I have written two projects which are required to be included in your solution. First is JohnKenedy.DataAccess and second is JohnKenedy.DataAccessModule. This is because the installation code is coming along with this library.
 4. The goal of this project is, user gets the installation files, double clicks the EXE, and clicks next and next following the instruction without the need to understand how to connect database, the database name, username, password and so on, user just clicks next and next, the application will install the.NET prerequisites, the database, and attach the database that programmer has created all automatically, and the application that programmer writes, runs and connects to the database without user knowing how to configure them. What user needs to know is only how to use the application that the programmer writes.
 1. Download the sample code I attach and extract it to D:\Software Pekerjaan\Makanan (I use for this example.)
 2. Assume the MenuMakanan project is the Windows Application project that you are creating and which is going to be deployed. From this project, add reference to library named JohnKenedy.DataAccess.
 3. Download MSDE by clicking here. Double click the.exe and by default it will extract to your C:\sql2ksp3. Copy the extracted contents to MenuMakanan project bin\debug\MSDE2000 folder.
 4. Detach your application's database to become MDF file, and copy the MDF file only to MenuMakanan project bin\debug\MSDE2000 folder. For this example, it is Food_Data.MDF which is contained in the download for example.
 5. In your application (MenuMakanan), add an Application Configuration file or app.config (in this sample, it already exists), and create two new keys in AppSettings section, read App.Config in sample for more information. Remember to set IsInstall=0, and IsRestart=0 as follows, because this will tell your application to install before running, IsRestart will be 1 if it is finished installing and requires to restart your computer so that the newly installed MSDE service is running.

 6. In your startup Form or form that is first run when application starts in this example is Login.cs, in the constructor after InitialilzeComponent, add codes that look like this:
 public Login()
 Installation _ins = new Installation(
 "Food", "JOHN", "MenuMakanan", "Food",
 if (_ins.IsDone == false) _ins.ShowDialog();
 if (_ins.IsRestart == true)
 3. Third is MenuMakanan, which is the new database instance that will be installed, this is similar with (local)\SQLExpress database instance that Microsoft installed when we install VS 2005, though this one is MSDE one. This name must be unique, and this database instance will only contain one database name which will be defined in the fourth parameter, and be used by your application only.
 5. Fifth is JOHNKENEDYDAL, which is the sa password for the newly installed MSDE, this password is required when you use Enterprise Manager (SQL 2000) to connect to the database instance.
 6. Food_Data.MDF is your MDF file name, that is stored in MenuMakanan project bin\debug\MSDE2000 folder. You can change this as it suits you.
Create Setup and Deployment Package
 1. Create a new Setup and Deployment project, in this sample it already exists with name SetupMakanan.
 2. In the application folder, create a new folder name MSDE2000, and inside this folder create three folder names Msi, MSM, and Setup. Then inside MSM folder, create a folder names 1033. This structure is the same with the MSDE extracted folder earlier in Step 3, we then add files to these folders MSDE2000, Msi, MSM, 1033, and Setup folder according to the MSDE extracted folders.
 3. Add Food_Data.MDF to MSDE2000 folder, because the Installation class will look for the filename in this folder. After step two and three, it will look like:
 Click here for a bigger image
 5. And then select the second radio button. Download prerequisites from the same location in my application. Click OK, and save.
 6. Build your whole solution, and then build SetupMakanan project, and you will see in SetupMakanan project debug folder Setup.exe SetupMakanan.msi, and two new folders, one is Windows Installer 3_1 and another is DotNetFX35 which are the.NET prerequisites.
This library is not fully for Installation, instead the library has Data Access feature, which article can be found here.
Installation is one of the features in the library I developed recently. I have tested the Setup package in a computer that never had.NET and database installed, and it did successfully install.NET and MSDE and run the application smoothly.

Volunteers arrive, two-by-two, every night for one week to monitor closely Mei Xiang and Tian Tian and record what they're up to -- or in some cases, not up to.
The night watch is historic because it is identical to the study conducted at the panda exhibit here 29 years ago when Ling-Ling and Hsing-Hsing were the residents of the panda exhibit. The data collected will be used to make comparisons amongst the four pandas to see if our panda couple in 2001 act any differently at night than Ling-Ling or Hsing-Hsing did in 1972.
When the night watch concludes, behaviorists will begin tabulating
the data they need to begin to draw conclusions. Both pandas
are watched simultaneously by two people who record the behaviors
of each animal. Start and stop times are written down for
rest/sleep, eating/drinking, grooming, bathing, scent marking,
urination/defecation, or a catch-all of "other" in which volunteers record rolling or anything else that doesn't
fit into the other categories. Also recorded is the exact
location of the indoor habitat of each panda throughout the
night. Scientists will be able to tell what proportion of
time is spent on their rocky substrate versus the floor.
Friends of the National Zoo volunteers who had not previously participated in Zoo research projects attended a three-hour "Historic Night Watch" training to prepare for their jobs. David Powell, postdoctoral scientist, giant panda behavior studies, played videotape of panda behaviors to show volunteers what to look for. That way, they could more easily recognize, differentiate, and record some of the subtle behaviors, like the difference between the squat posture and the hand stand when scent-marking. So far, Mei Xiang and Tian Tian have only been seen scent-marking in the squat posture, so perhaps a new technique will be seen for the first time this week.
To ensure that comparisons are valid, duplicating as closely as possible the original study conducted with Ling-Ling and Hsing-Hsing in 1972 is a top priority. It helps having Nell Ball, a volunteer who participated in a previous night watch, train less experienced volunteers and share specifics about how details were recorded.

More than finding your place in the world, Kid-Architect is about making it.
Through the use of the most basic building block of space of our time – the box – children can explore the composition of space, forming it as they wish and improvising as they play.
Applying the simple box layout promotes an intuitive understanding of form and function, making the play process more accessible.
Suitable for children ages 5-11 Kid-Architect helps create a sense of space and volume while developing the child's ability to take into account multiple aspects of problem solving by enabling him to form various shapes/spaces using the same given objects.
With simple design and choice of basic materials it may be used in a variety of ways over different periods of time. By using more panels you increase the volume of buildable space as well as the number of options for this three dimensional composing.
As children grow, Kid-Architect grows with them.
Kid-Architect is made from recycled foam cut into 60X60X1.5cm pieces. Each two pieces are glued together with an added rip-stop cloth protruding from one side in order to attach permanently to other pieces.
The temporary connection of pieces during the game is done with Velcro attached to the edges. In order to be able to connect any two parts together Velcro is assembled in a way which produces no two similar strips thus eliminating the dependence on a polarized system.

Multimedia Case Study > Tip the Balance on Waste
"Tip the Balance - on Waste" is a waste reduction programme designed by Hot PJ for senior primary students within Canterbury.
Developed by Environment Canterbury on behalf of the Canterbury Joint Waste Committee, "Tip the Balance" is designed to challenge students to rethink the choices they make when it comes to choosing their school lunch, with the aim of reducing waste.
Students embark on a proactive journey:
- travelling back through the life cycle of an aluminium can - a very long life!
- making choices about what food and drink to have in their lunch box
- finding out how 'wastewise' these lunch choices are
- comparing their choices with a group of virtual friends and seeing who ends up with the best 'wastewise' score.
The interactive resource is supported with a Student Workbook and a Facilitator's Guide.

The Suriname Dollar (SRD) has been the national currency since 2004. There are coins in denominations of 1,5,10,25,100 and 250 cents, and bank bills of 5,10,20,50 and 100 Dollars. You can view the exchange rates each day in the local newspapers. US Dollars and Euros can be exchanged at all national and local banks. Traveller's cheques can only be exchanged at local banks. Under no circumstances should you ever exchange money on the streets!
You can also use your ATM or credit card. In the interior of the country, this option is obviously not available. If necessary, you can ask your tour guide which destinations within the country will require you to have cash on hand.
There are plenty of ATMs in Paramaribo where you can use your ATM card to pick up cash. Banks are only open in the morning from 8:00 am to 2:00 pm. Exchange offices (Cambios) are often open until 9:00 pm in the evening.
Good monetary prospects for Suriname
Suriname's economy displays economic stability for a number of years. It is very important that the current foundation is developing more.
In 2004, three zeros were scraped from the Surinamese guilder and the name was changed to the Suriname Dollar, the SRD. This decision was taken by the Central Bank of Suriname, because the value of the Surinamese currency was declining. This was the way to make money valuable again.
It can be said today the monetary reserves of Suriname are at peaks. This means that the Surinamese economy is strong and has the reserves to show that. There are three reasons why the monetary reserves are so important for our country:
- The reserves cover the money brought into circulation. When this is not the case then the zeros appear again causing inflation. The Central Bank of Suriname is the only institute that can put money into circulation. And since 2005, the line was tightened. The Central Bank may only spend money if they have coverage.
- The reserves cover the currency accounts of other banks. Banks are at high risk because of the foreign currency management and should be able to pay back customers at all the time. These banks are required to deposit 1/3 of the currency separate to an escrow account so the money is kept safe. The Central Bank of Suriname will back up the banks if they get into trouble and cannot pay their customers.
- The reserves provide a certain amount of credit on the capital market. This is especially necessary now that the development aid is finished. Suriname is now dependent on international capital markets, where there is a need for monetary reserves.
The Surinamese currency is healthy, fully covered and is safe to invest. There is no doubt that there is economic stability, for the purchasing power has together with the Gross National Product doubled in the past five years.

Looking at the source, it could be that Mechanize is supposed to work like that. It forces the form method to uppercase when it fetches the form; you are expected to supply the method in uppercase when you want to match it. You might ping the mechanize person(s) and ask them if it's supposed to work like that.
Here in Mechanize.submit, it forces the form method to uppercase before comparing it:
def submit(form, button=nil, headers={})
 case form.method.upcase
 when 'POST'
 when 'GET'
and here again in Form.initialize, the method is forced to uppercase:
 def initialize(node, mech=nil, page=nil)
 _USER_ = (node['method'] || 'GET').upcase
But in page.rb is the code where mechanize is matching a form (or link, base, frame or iframe) against the parameters you gave, the parameter you passed in is not forced to uppercase, so it's a case sensitive match:
 def #{type}s_with(criteria)
 criteria = {:name => criteria} if String === criteria
 f = #{type}s.find_all do |thing|
 criteria.all? { |k,v| v === thing.send(k) }
 yield f if block_given?
Well, it's a case sensitive match if you pass in a string. But if you pass in a regex, it's a regex match. So you ought to be able to do this:
login_form = page.form_with(:method => /post/i)
and have it work fine. But I would probably just pass in an uppercase String, send the Mechanize person(s) an email, and move on.

How Do Snails Make Shells – How are They Formed
I was doing a bit of gardening recently when I came across a snail with a chunk of its shell missing. I thought to myself, how do these shells work? I wander if the little guy can grow another one…? I did some further digging, excuse the pun, and this is what I uncovered!
How do snails make shells?
Snails make their shells with a gland called the 'mucous pedal gland'. The function of this gland is to produce a calcium rich mucous which the snail spreads on the outer rim of the original shell. Over time this mucous hardens, at first forming a weak, soft edge that eventually becomes hard like the rest. This process is repeated as necessary to ensure the shell grows along with the snail. Land, garden and sea snails all follow the same shell growth process.
Through my research I also discovered that there are over forty thousand species of snail and some of them only live in water. Can you imagine that?! I also discovered just how important a role the shells play in the life of a snail and how some of their reproductive methods are totally crazy. Check this out!
Do snails have shells when they are born
All snails are born with a basic soft shell called a 'protoconch'. The shells are made of calcium carbonate, which is a chemical compound of calcium and protein also found in rocks, seashells and even dark green vegetables.
Where Do Snail Shells come from & How are Snail Shells Formed
As a snail reaches maturity, their original shell becomes the smallest part of the spiral we see in all snail shells. As the shell grows, it is pushed around the snail like an unwinding spring, this is the reason for the spiral shape. Because of the way the snail forms it's shell it is also capable of repairing it, the mucous excretion acting like glue to seal a wound – so I'm sure my little garden friend will be fine.
Now, given that the shell is made of calcium carbonate, you might have guessed that the main ingredient for the shell is calcium – this means that to grow a shell effectively, snails must consume large quantities of it to fuel their mucous production. All snails hatch from calcium dense eggs and instinct tells them to eat the eggshell after they hatch. This sets them on the path of seeking out calcium – from birth they hunt for anything and everything plant based containing this essential dietary ingredient (snails are omnivores with very few genetically exceptional species that may occasionally eat fish or other snails).
Land snails often look for green vegetables such as spinach and broccoli. Snails that spend their lives in the water have a diet primarily consisting of plants like algae and kelp.
Diet has a large impact on the pattern of the shell too! Snails with a diverse diet tend to have more vibrant and interesting patterned shell, which is why sea snails living in warmer climates tend to be the most eye-catching, due to the larger variety of available foods.
How Do Snails Make Shells
How Do Snails Make Shells
Why do snails have a shell?
The purpose of a snail's shell is very diverse and it's kind of like a little snail house, though it's technically a living part of the snail. Because of the genetic make-up of a snail, like all members of the gastropod family, their entire body is very moist – maintained by their mucous production mentioned earlier – as such, they require a moist environment to survive.
This is why we rarely see snails on the sidewalk when it's sunny and dry, it makes it very difficult and uncomfortable for the snail to move around as it has to produce far more mucous to do so. If it's really hot, then the shell acts as a very necessary sun shield where the snail can retreat into and stay nice and wet. Shells are also very useful as a means of defence against predators such as birds and fish – the strong shell being virtually impenetrable to many species.
They can also hide well as their shells often camouflage well with the environment in which they get their food from – as I mentioned earlier, the shell pattern and colour changes based on diet. If a snail feels threatened it can retract its entire body into the shell so that only very persistent and well-equipped predators can get at them. Birds like the song thrush will clasp a snail in its strong beak and repeatedly smash it against a solid object until they successfully break the hard shell.
Other large predators such as blue jays, ravens, hawks and owls will actually swallow smaller snails whole, in which case the shells are likely only to cause a minor stomach upset for their attackers…hardly a fair trade!
How are snails attached to their shells?
While we might look at the shell as the snail's home, it is attached from birth and cannot be removed. The shell should be considered as an extension of the snail itself, like a human's ribcage.
Can a snail live without its shell or Do Snails Die when their Shells Break?
The short answer is, sadly, no. So, if my little friend's shell was more severely damaged, he probably wouldn't have made it.
Imagine if your rib cage was on the outside of your body. Our ribcage is very important for our survival as it protects our important bits! Without our ribcage we couldn't survive as it supports our ability to breathe and it is the same for the snail. Not only does the snail breathe through a breathing hole in its shell, it simply wouldn't survive the elements without it. Who would have known that a snail's greatest defence mechanism is also one of its most vital organs!
Can snails regrow their shells?
As mentioned earlier, a snail can make minor repairs to their shell as needed, however, to regrow the entire shell would sadly be impossible because to lose the shell means death.
Where do snails come from? Reproduction and more!
One of the most interesting finds I came across in my search for snail information is that the majority of snails don't reproduce like humans, or many other mammals at that. In fact, their reproduction methods are incredibly rare in the sense that most snails are hermaphrodites. This means that the snail is both male and female – possessing all necessary elements required to produce both egg and sperm. This means that a snail can reproduce all by itself, isn't that crazy?! While it is possible for snails to reproduce by themselves, they generally prefer to find a mate, because the chance of survival for a baby snail that is self-fertilised is much lower than if they produce with a sexual partner.
One of the most fascinating discoveries I came across is that some species of snail use a mechanism commonly called a 'love dart'. Love darts are made up of calcium and contain hormones that help to enhance reproductive capability of the party that is 'shot' with the dart. Love darts are typically present in snails who have been sexually mature for a while and reproduced in the past. In the final stages of reproduction snails will shoot these love darts into their sexual partners as a part of the mating ritual.
The only problem is that sometimes these darts that are designed to help with successful reproduction, actually have the potential to pass right through the snail on impact and damage vital organs! It's a good thing these snails don't have thought processes like human beings – they are very instinct oriented beings. Otherwise these particular species would probably die out from fear of reproducing!
Save the snail shell!
What a journey that was – I hope you enjoyed learning about snails as much as I did! Remember that all snails are born with their shell and that it is vital for their survival. So, if you're ever in the garden and you see a snail with a cracked shell, you can help the snail by moving it out of the sun so that it doesn't dry out while it's repairing itself. Some people have been recorded to use glue or sticky tape successfully to help fix snail shells, but that might be a level of commitment you're not looking for with your little garden friends. (Or pests, depending on who you ask!)

Project Euler Problem 5 in F#
Yet another episode in my attempts to solve Project Euler problems.
Enter problem number 5:
I'll first show you my solution and then explain the bits:
// greatest common divisor (Euclid Algorithm)
let rec gcd (a:int64, b:int64) =
 match b with
 | x when x = 0L -> a
 | _ -> gcd (b, a % b)
// least common divisor
let rec lcm (a:int64, b:int64) =
 (a * b) / gcd (a,b)
// least common divisor for a list of numbers
let rec lcmlist (list: int64 list) =
 match list with
 | [] -> 1L
 | [a] -> a
 | [a;b] -> lcm(a,b)
 | h::t -> lcm(h, lcmlist t)
// utility to generate a list of all integers
// up to a certain number
let generateListTo top =
 let l = [for i in 1L.. int64 top -> i]
let resolveProblem5 =
 generateListTo 20 |> lcmlist
The first thing to realize when reading this problem is that what is really being asked is
the least common multiple (lcm from now on) of a list of numbers (in particular, the numbers from 1 to 20 included).
There's a straightforward way to compute the lcm, by using the greatest common divisor (gcd), as follows:
Least Common Multiple
As for the gcd itself, it can be easily implemented using the Euclid Algorithm.
The last piece of the puzzle comes when you realize how calculating the lcd of a set of numbers can be reduced to calculating lcds pair-wise in the following fashion:
Lcm on a list of numbers
For example, given the numbers 3, 4, 14, and 18, their lcm would be computed in the following way:
Least Common Multiple=
As you can see, the algorithm lends itself beautifully to recursion and such is the solution that I have provided.
See all Project Euler problems solutions.

 Thanks for the gcd & lcm algorithm. Nice work, and explanation – this is a very good solution. It is many times faster than the brute force approach I tried.
 Just a minor F# point. "[for i in 1L.. int64 top -> i]" is the same as "[]". In fact, the last two functions can be compressed to just "[1L..20L] |> lcmlist"

 Yes, you have a good point there. I am trying to get familiar with F# own idioms more and more, even though my C# background creeps in from time to time :)

How To Make a Simple iPhone Amplifier
video How To Make a Simple iPhone Amplifier
You can make a simple, passive iPhone amplifier with a bowl or deodorant cap. This video shows how and why it works.
stubbsonic1 year ago
I think the theory that is mentioned in the video is a little misleading. Sound waves from the iPhone® speaker propagate (fancy word) in all directions. Placing the speaker in a bowl not only causes the waves that would have been directed away from the phone to be bounced back-- to join the waves already headed toward your ears-- but it also focuses them (because the bowl is concave). In other words, it acts like a lens to focus the waves reflection into a narrower beam.
The deodorant cap seems to do two things, both resonating and reflecting/focusing. But I'd be curious to know exactly why the vibrations emanating from the iPhone® speaker are not as loud as with the cap on, since the cap also propagates the same sound energy in all directions-- and in fact it loses some of that energy as the cap is not without it's kinetic losses.
HowToLou (author) stubbsonic1 year ago
You are right about increased focus, but the gain amplitude gain comes from matching the acoustic impedance of the speaker to that of the air, as the video demonstrated with the water table. See
Thanks for that info. I'm going to have to study "acoustic impedance" (I've not heard of it until now).
