Pros and cons of welfare?

"Welfare can be good, and allow a single-mother get back on her feet. However, many people abuse the welfare system and simple have children so they can continue to receive more money for a longer period of time. The needs of the children should always come first. Therefore, welfare is doing some good by providing children with food and shelter. But, is welfare really providing children with food and shelter? If a single mother on welfare used only her monthly welfare check she would be in debt by at least $50. However, that would be only if she used to money on food and shelter. That does not even include other necessities, such as clothing, furnature, transportation, soap, ect. In my opinion, welfare is doing more harm than good, but the choice is up to you."

What are the pros and cons of caucuses?

Caucuses allow members of the party they're looking to represent to show their beliefs on controversial subjects. This is definitely a pro, as the party members and voters can see the best side of the candidates. However, only extremists and activists tend to attend caucuses, which means that only they are represented on election day.

Describe the comparison between publicly funded and privately funded prisons?

Publicly funded prisons are supported by our tax dollars and run by individuals working directly for the state. They are entitled to the benefits of any state employee. Privately funded prisons are run by private individuals under contract to the state and are under strict controls by the state. However, they are sometimes more flexible and less effective. It's just a way of life in prison. You're in a place filled with convicted criminals. Of course you're going to team up with a gang, which in that case is your race. They protect and take care of each other. It's a sense of security, also mandatory. Nobody likes being locked up and being told what to do. You hate the authority figures that put you in there thus the correctional officer's you see every day. It will never change.

Prison's are now a way to make money. Private prisons are a business like any other. The state pay's that prison a certain amount each year to take care of that prisoner. It also takes some of the responsibility off the state. There are 23 million convicted felons in this country and it grows by the thousands each month. This is a way for people in power to make money off taxpayers. My question would be if this is a business that makes so much money then why they wouldn't have some kind of rehabilitation classes or some kind of program that teaches responsibility and success rather then throw all these people in a place of criminal education. IT MAKES MONEY. A lot of people who get out are more likely to go back in the next two years, then get a good job or go to school. Why? They are now a convicted felon with a tag on them that will not allow them to be a successful productive citizen. Every place of business now day's does a background check. If we were put in there to pay our debt to society and be rehabilitated.

Comparison between call money market and Treasury bills market?

The call

money market

is a market that consists of the borrowing of money by brokers and dealers for the purpose of meeting their credit needs.



Generally, this money is used to either cover their customers' margin accounts or finance their own inventory of securities. Along with day-to-day loans, call money loans play a significant role in interbank money dealing and between banks and money market dealers. The term "call money" alone usually refers to either secured or unsecured callable loans made by banks to money market dealers. Generally, these loans are made on a short term basis.



Treasury bills

(also known as T-bills) are the most marketable money market security. Their popularity is mainly due to their simplicity. Essentially, T-bills are a way for the U.S. government to raise money from the public.



T-bills are short-term securities that mature in one year or less from their issue date. They are issued with 3-month, 6-month, and one-year maturities. T-bills are purchased for a price that is less than their par (face) value; when they mature, the government pays the holder the full par value. Effectively, your interest is the difference between the purchase price of the security and what you get at maturity.



Treasury bills (as well as notes and bonds) are issued through a

competitive bidding

process at auction. If you want to buy a T-bill, you submit a bid that is prepared either non-competitively or competitively. In non-competitive bidding, you'll receive the full amount of the security you want at the return determined at the auction. With competitive bidding, you have to specify the return that you would like to receive. If the return you specify is too high, you might not receive any securities, or just a portion of what you bid for.

What is the difference between D-glucose and L-glucose?

You can see in the above image the only difference is the position of the hydroxyl group (OH) on the carbon chain. They are mirror images of the other but they do not overlap. L-Glucose has to be made in a lab, whereas D-Glucose is naturally occurring. I've written an answer to the following question that might give you some more insight to the pathways involved.

What are the comparisons between motors and generators?

Electric Motors

• The electric motor converts electrical energy into mechanical energy

• The shaft of a motor is driven by the magnetic forces developed between the armature and field

• Current has to be supplied to the armature winding.

• Motors obey Fleming`s Left Hand Rule

• Electric Motors Fleming`s Left Hand Rule The Left Hand Rule shows what happens when charged particles enter a magnetic field.

Generators

• A generator converts mechanical energy into electrical energy.

• A shaft attached to the rotor is driven by a mechanical force

• Electric current is produced in the armature windings.

• Generators obey Fleming's Right Hand Rule

• Generators The Right Hand Rule shows how a current-carrying wire generates a magnetic field.

What are the pros and cons of being a agent?

PROS- dead bodies, blood, dress up, fighting, screaming, cool shades, MIB gear, sexy men, bad boys, dirty money CONS- working, physical activity.

How does SmarterChild work?

Smarter Child is a weirdo robot from AIM but it is sponsored by AOL so I know its a robot.

How large is a giraffe in comparison to a human?

Huge

A male Giraffe is 15 to 18 feet tall regularly, which is equal to 4.5 to 5.5 metres. Roughly 3 times taller than a human.

They can weigh from 2000 to 4000 pounds; which is from 900 to 1800 kilo

A record holding giant giraffe stood 20 feet tall and weight 4500 lb; That is 6.09 metres and 2042 kg.

Effects of Hydrocodone?

There are several different effects of hydrocodone. Some of these side effects include nausea, vomiting, constipation, drowsiness, dizziness, anxiety, itching, and a rash.

What are the advantages and disadvantages of the Selective Repeat protocol in comparison with Go-Back-N?

Using the Go Back N protocol for error control means that if a timeout occurs, then all unacknowledged packets are resent, where with selective repeat, only those packets that were unacknowledged. This allows the Go Back N to use cumulative acknowledgements, creating a faster data flow, but this also means that in the case of an interruption, the system is slower to recognize this and then time is lost for the retransmission since the last cumulative ack.

Does horoscope work?

The thing about this is that things like this are just peoples readings or interpretation about that stars and your brithday, if you choose to believe it then it would be up to you on how you would interpret those readings and use it in your life. == == There is a very broad definition that horoscopes give, as so many people are in the same general sun/moon/planet section. To read a horoscope, you have to get it's interpretation to nearly fit your pending belief to accept or avoid any stated actions. And that's where the horoscopes appear to work.

What is the difference between the old and the elderly?

Nothing really. Elderly is a polite way to say an old person i.e a 70year old. Old is slightly ruder and is also used to describe objects rather than people.

What is the difference between Carbon fibre and Kevlar?

Kevlar 29 is used for bullet proof vests. Kevlar 49 is used in light weight construction or semi loaded structure, F1, Indy cars and an acceptable material for side protection, for SCCA racing body parts. Kevlar 49 is the preferred material to use on more expensive, modern light weight sail planes or canoes.

Some of the negatives of Kevlar are, it is hard to work with, more set up time is necessary then fiber glass, it is not very easy to cut, it has a tendency to buckle under compression. the simple wet hand lay up process is not preferred, the VARTM or vacuum assisted resin transfer molding lay up process is the preferred method for proper absorption. The positives of Kevlar are it is lighter, then both carbon fiber and fiber glass, its tensile strength is higher then, carbon fiber, but it is not as stiff as carbon fiber. Kevlar is extremely tough and abrasion resistant, Kevlar falls in between S2 fiberglass and Carbon fiber in cost and stiffness. Carbon fiber on the other hand has been used for Race chassis and it is extremely stiff and strong. Once Kevlar has been over loaded it will yield to a degree like steel, this is where Kevlar will show its toughness.

On the other hand the negatives of Carbon fiber are it is very brittle and less tough than kevlar, once the maximum load has been reached for carbon fiber it will disintegrate or shatter under high energy impact literally explode, gone ! So your feet or legs are left to dangle and flip around with the rest of the race car chassis smashing into everything until the chassis comes to a complete stop. This exposure is not good for the human body. The fragments and splinters from Carbon fiber are very painful and may require magnified surgery for removal. The positives of Carbon fiber are it is very stiff and can help to make structures being constructed with it even stiffer and lighter with its use , in combination with EV or HT resins systems it is used as loaded structure. and it is not as expensive or as toxic as Boron fiber. And it reveals a beautiful appearance through clear and transparent resin's.

In England, race car Designer Colin Chapman from lotus started using a Carbon / Kevlar hybrid cloth an 85/15 type ratio where the two fiber strands combined together seemed to make for a wonderful cloth for composites, this combination seemed to help keep the pieces together, even after a few good impacts. But unfortunately due to pressure to compete against one another as race teams do, making race cars faster is race teams job. So a better handling car means greater ft lbs. per degree of stiffness in the chassis, so for some race teams out went the Kevlar for safety and back to the all Carbon fiber chassis.

The current engineer's concept and standard here today is that if they use mostly intermediate modulus carbon fiber and some higher modulus carbon fiber in a fewer key select areas, combined with using the new advancements that have been made to epoxies, combining micro particle's at 100 nm in size to reduce the occurrence of micro cracking during the curing process, these particle's help to increase the composites toughness in the finished stage enough so to withstand against any applied loads to the structure without the Kevlar the carbon fiber then is able to hold up against any impact forces, it may experience during a crash.

So the Carbon fibers toughness becomes primary and the added Kevlar as a safety become's secondary, To exclude Kevlar as a fail safe material from a race chassis design altogether removes a factor of safety that was once realized. possibly a shared approach with the intermediate modulus carbon fiber and Kevlar blend as a cloth with the micro particle's blended in the epoxy resin as for the interior layers just as a fail safe to prevent any protrusion's could be the possible method of thought, as seen in some of the higher end Sports racing classes like GTP and World cup series interior's used for safety. I also believe the improvements made by using micro particle's at 100 nm in size in combination in use with the epoxy, some of the tragic occurrences such as structural failure we've seen over the years on race tracks, will be a thing from the past.

The development and full understanding of these modern composites materials is ongoing and is still in its beginning stage's no one knows everything they can about these materials, so many variables are involved. One should always work towards gaining a better understanding through a scientific approach, from testing and research. These engineering Materials and their manufacturing processes can have an effect or change on the other materials properties once they are combined, this is typical. A clear understanding of their effects upon the other and their properties combined as a whole, should be understood first, before designing anything.
