by material and by type. In addition to the obvious evaluation factors as age, rarity, integrity, and the fame of the builder, consideration also is given to the substructure (piers, abutments, foundation), the superstructure (beam, arch, truss, suspension, and combinations thereof), the materials of construction (their strength and properties), the evolution of construction techniques, and whether the bridge advanced structural theory or methods of evaluating material behaviour. Bridges discussed in this essay illustrate important types or technological turning points and are listed at the end. Some, like the Pont du Gard (France) and the Iron Bridge (UK), are already inscribed on the World Heritage List. Others may be candidates for listing given adequate study, comparison, and evaluation. Not every potential World Heritage bridge candidate is cited. It is the

Clay Bricks

Introduction (slide 2) In this presentation I'd like to give a brief overview of clay bricks. I'll speak about 15min to allow time for questions at the end. Firstly clay bricks are known for centuries as one of the most solid and reliable structural elements is set to play a role in reducing global warming. Apart form the many benefits obtained from using clay bricks in construction, such as their durability, insulation properties and aesthetic qualities, recent findings show that they also produce less carbon emissions than any other masonry material. History (slide 3) In more detail the earliest bricks were dried bricks, meaning they were formed from clay-

Home description

My house was built in 1992 but it has been extensively modernised and extended since then. Our house consists a lot of different elements and components what I try to describe in my essay. The most important part of construction is foundation because it keeps buildings in one piece. My house has a strip foundation which is taken 1,5m below the ground to protect the structure against ground movement and damages. Due to the fact that foundation transfer the dead and imposed loads of the structure onto the ground it must be very solid and strong. Our foundation is made of pre cast concrete blocks which has a damp-proof course made of mastics on external side. There are sleeper wall after the concrete blocks to support the basement floor slabs. Next primary elements are the walls. My house has four crosswalls which have load bearing and enclosing role. There are also a lot of internal division walls with dividing role. The crosswalls are made of lightweight concrete blocks

Acid Rain

5­4.9 Harmful to the eggs of salmon and trout species (salmonids) and to adult fish when levels of Ca 2, Na and Cl are low 4.0­4.4 Harmful to adult fish of many types which have not been progressively acclimated to low pH 3.5­3.9 Lethal to salmonids, although acclimated roach can survive for longer 3.0­3.4 Most fish are killed within hours at these levels Environmental effects Very obvious environmental effect of acid rain is the loss of fish in acid sensitive lakes and streams. Loads of fishes are not able to survive in acidic water. There are 2 ways acid rain effects lakes and streams: chronic and episodic. The first one is long-term process and this acidification is result from years of acidic rainfall. Episodic, on the other hand, is rapid change ­ sudden jump in the acidity of water. Acid deposition may influence forest vegetation and soils. It removes soil nutrients such as calcium and magnesium from soils in high elevation forests

He has examined a whole portfo- lio of dose-response relationships with physical, perceptual and biochemical measures in rested and fatigued states, all of which will be published in due course. He is now a lecturer in exercise physiology at Newman University, Birmingham and a consultant to
