One major consideration when planning cable duct and trays is the bending radius, the bends must have smooth curves. Although conduits can still be used inside the building, so when a cable is pulled into a conduit, the conduit’s bending radius must be larger than the cable’s minimum bending radius for loaded conditions. Direct burial, aerial and blown fiber installations. Most common is the use of direct burial installations for long cross-country installations. The cables are plowed in or buried in
Conduit - A rigid or flexible metallic or nonmetallic raceway of circular cross section in which cables are housed for protection and to prevent burning cable from spreading flames or smoke in the event of a fire. Racks - A frame-like structure where patch panels, switches, and other network equipment are installed. The typical dimension is 19 inches. Punch-down blocks - A generic name for any cross-connect block where the individual wires in UTP are placed into a terminal groove and “punched down” with a special tool. The groove pierces the insulation and makes contact with the inner conductor.
ASSESSMENT TASK 1 – EXPLAINING CONTRACT CLAUSES In your own words, write down what the obligations and responsibilities for each party are. What procedures do you need to follow to comply with these? 1. Clause ; breach of contract (both the owner and builder) A breach of contract occurs when either party fails in their obligations as stated in the contract. Builders Obligations : Warranties as per Section 8 of the Domestic Building Contracts Act 1995 a) The builder has to carry out the contracted work in a proper and workman like manner as set out in the contract, plans and specifications b) The builder has to use good and suitable materials for the contracted works and unless stated in the contract these materials are to be new c) The
In addition Barnacles secrete a cement. This allows them to “stick” to the rock and maintain moisture when exposed.
Compound Epithelium – this type of epithelial tissue is made to withstand wear and tear. It is composed by several layers of cells which is the reason for the name of the cell. The epithelium may or may not be keratinised which contains a tough, resistant protein called keratin for example skin or unkeratinised which is what the lining of your mouth is made up of. Unstriated muscle – this is the type of muscle which still contains protein filaments but they do not lie in an orderly pattern as with striated muscle. In this type of muscle the fibres are spindle shaped and generally have a central nucleus, and dove-tail into each other.
3- Describe the [location, composition, and function] of the epiphyseal plate. The epiphyseal plate is located in the metaphysis and is composed of hyaline cartilage. It is the growth plate, it covers the part of the epiphysis where the bone forms an articulation with another bone. It reduces friction and absorbs shock in articular cartilage. In the periosteum it surrounds the bone surface wherever it is not covered by articular cartilage, it is a sheath of dense irregular connective tissue containing osteoblasts, it functions to protect the bone, assists in fracture repair, nourishes bone tissue, and serves as an attachment point for ligaments and tendons.
Write True or False : 1. If the amount of large and fine particles is about the same, then the soil is called loamy soil. 2. The layer which is hard and difficult to dig with spade is called top soil. 3.
The volume of the fracking fluid ejected through the pores exceeds the volume of the same that penetrates to the target zones. As a result, there is accumulation of the fluid and this raises the pressure to a point that forces the rocks in the target zones to crack. The flow of the fluid into the well then stops, and the fluid begins to flow into the opposite direction (upwards) to eject the fluid. Within the fluid are components called proppats, which could be sand or ceramics (Mooney, 2011). These do not flow out of the fractured target zones.
Special Precautions Special precautions should be taken against entry into confined spaces and working at height. Harmful manual handling should be eliminated. Lifting plant and pressure systems should be regularly eliminated. Safe use of electricity and site transport should be ensured.

Studies have been done, from measuring the effects on drinking water to monitoring seismic events related to fracking. While the validity and interpretation of these studies can be brought under scrutiny depending on the viewpoint of the respective group, the mining of the required silica sands and the damages it is ensuing on the environment must be taken into
