Can you suggest some different names for paper presentation?

you mean diff names for 'paper presentation' or diff names for YOUR presentation? well..... given i have info for the first i would suggest changing it around by using

--these are things you can do to subjects, topics, and speaking points-

explore, elaborate on, discuss, observe..

and how do i use these???

like so..

instead of 'im gonna recite my paper presentation in a frowningly dull way'

'today i'd like to explore the subject of (capitalism, fascism, w/e your paper or first point is)

(this is the end of the first point of topic) .. and with that being said / .. and knowing that, (on to your next topic) we can elaborate on what (???) is exactly.. now we're going to discuss... and .. (use questions addressing your audience) did you observe any differences between this and that, or how you viewed this topic before and after becoming educated about it.. ...... if you want a more straightforward answer, give a straight forward question.

Can beach sand be used as a underlayment for concrete?

It is not recommended as it contains salts and debris that will cause concrete failure.

Why is the compressive strength of wood more along grains?

it depends upon the sliding of fibers or grains on each other, if sliding is more so you will get more compressive strength.

What is mean by sag ratio in bridge?

The sag ratio relates to suspension bridges. For cable-stayed bridges we talk about span ratio. They are the same thing but they're called differently simply because the cable of a suspension bridge sags.

The sag (or span ratio) is the ratio between the total distance c/c (center to center) between the pylons and the height of the pylons from the deck to the top.

Usually for suspension bridges the sag ratio is 1:9 or 1:10 for better aesthetic results.

What is tension on a bridge?

Tension is a force on a bridge that pulls, or acts to expand the thing it is acting on.

What is the origin of Ceramics?

ceramic creations originate from Greece or the ancient Elada =]

What is a street divider?

a concret beam or slab that seperates drivers coming towards other drivers

What is hydraulic conductivity of soil?

This depends on the soil!

Cohesionless coarse grained soils with high gravel contents may have high hydraulic conductivity on the order of 1 to 1x10-1 m/s.

Mixed sands and gravels are on the order of 1x10-1 to 1x10-3 m/s.

Finer sands approximately 1x10-3 to 1x10-4, and fine grained soils such as silty sands may be in the range of 1x10-5 to 1x10-7 m/s.

Very fine grained cohesive clay soils have very low hydraulic conductivity values ranging from 1x10-7 to 1x10-13 m/s.

What time did the World Trade Center fall and which building fell first?

On September 11, 2001 at 8:46 a.m. Eastern Time, Al Qaeda suicide hijackers crashed American Airlines Flight 11 into the northern facade of the North Tower.

What is the upper limit of ultimate tensile strength of ASTM-615A bars above which rejection is recommended?

Why would you reject material that overperformed its tensile-strength specs? The standard for Concrete Reinforcement rebar,astm-615a Grade 60 (60,000 PSI minimum yield strength)

What is the definitions of Tensile and shear adhesion?

How we can define Tensile and shear adhesion strength in terms of bonding of two objects.

What is the density of reinforced concrete grade 40?
