The lungs are made up of many types of tissue; the cartilages‚ ciliated epithelium‚ smooth muscle‚ squamous epithelium‚ elastic fibres and goblet cells and glandular tissue. The cartilage is a very stiff and flexible tissue‚ which doesn’t contain air vessels. It is found in trachea‚ bronchus‚ bronchiole and alveolus‚ and it has a structural role. It support‚ and gives strength to trachea and bronchi. It holds the airways open for the resistance with little airway. This prevents it from collapse

network is usually clustered in close proximity to other computing resources but may also extend to remote locations for backup and archival storage. A storage area network can use existing communication technology optical fiber or it may use the newer Fibre Channel technology. Some SAN system integrators liken it to the common storage bus (flow of data) in a personal computer that is shared by different kinds of storage devices such as a hard disk or a CD-ROM player. SANs support disk mirroring‚ backup

body and consists of two layers mainly the epidermis and the dermis. Also beneath the dermis is the subcutaneous layer which is not part of the skin but separates the integument from muscles and bones‚ which will be included in the essay as tissue fibres are connected with those of the dermis. The main functions of the skin are protection of the tissues and organs that lie beneath against bumps and shocks‚ prevents entry of microorganisms and controls entry of foreign materials‚ protects the body

means that composite materials can be cut significantly faster than metals. M.A. Azmir et al carried out a study on the effect of abrasive water jet machining (AWJM) process parameters on surface roughness (Ra) and kerf taper ratio (TR) of aramid fibre reinforced plastics (AFRP) composite. Taguchi’s design of experiment was used as the experimental approach. Through analysis of variance (ANOVA)‚ it was found that the traverse rate was considered to be the most significant factor in both Ra and TR

characteristics for dispersion dies (hydrophobic substances in general) and his low viscosity. The CO2 loaded with the colouring can penetrate therefore deeply into the pore system and capillary system of the textile fibre and causes thus an intensive colouring of hydrophobic synthesis fibres like polyester‚ Elastan and nylon. The results of numerous dyeing with supercritical CO2 in Uhde lab and pilot plants speak for the high potential of this application. Besides‚ yarn and fabrics with the highest colour

Since the world of construction nowadays have been favouring environmental friendly material in construction with the lowest cost possible‚ this section will also discuss about the benefits of each material to the environment. Glass Fibre Reinforced Polymer Glass Fibre Reinforced Polymer or GFRP is a material that can be shaped into almost any shape. The example of GFRP is shown in figure xx. This material can replace cold rolled steel as purlins or girts. If GRFP is utilized‚ the portal frame section

sent from motor neurons to skeletal muscle fibres to warrant movement of muscles is called neuromuscular junction (Etherington & Hong‚ 2011). Motor neurons‚ Schwann cells‚ muscle fibres and kranocytes are all the different cell types that make up the neuromuscular junction. Motor neurons send out axons to skeletal muscles where an action potential is passed along the axons. The axons form a synaptic knob where they send activation signals to muscle fibres (Etherington & Hong‚ 2011). Muscles are

There have been multiple theories considered to explain the process of referred pain. One theory discusses the branching of peripheral nociceptive afferent fibres that has a receptive field in both the local and referred pain area.1 The limitation for this theory is that these bifurcated fibres are rare‚ fibres don’t generally branch over such large distances‚ semi-directional nature of referred pain & the latency of onset.2 This theory implies that if one receptive field is stimulated it will lead

Supports softer tissues in nose‚ ear‚ trachea. Also acts as shock absorbers in spine. Contains elastin and collagen fibres. Bone – formed from calcium salts deposited around proteins. Calcium salts are rigid‚ protein fibres provide elasticity and strength Areolar – contains cells called fibroblasts separated by non-living matrix. Collagen fibres for flexibility‚ elastic fibres for stretching. Found in skin‚ most internal organs (for expansion)‚ muscles/blood vessels/nerves for protection.
