Effect of Age of PWV and arterial stiffness Aortic PVW has been shown to be one of the best independent predictors of cardiovascular mortality in many populations. It has been shown to be a powerful predictor of cardiovascular death in essential hypertensive patients with end-stage renal disease where SBP or PP was not as effective [68]. It has been shown to be more effective at predicting mortality in diabetics than SBP [69]. PWV has also been proven to be the best predictors of cardiovascular

Failure criteria’s plays very important role in analysing the failure and predicting the mechanical properties of composite materials. There are many failure criteria’s available which has aided in analysing, few such failure criteria’s are maximum stress, maximum strain, Classic laminate theory, Hashin’s failure theory, Tsai-Wu failure criterion, and Tsai-Hill failure criterion etc. The research was conducted on failure ways and criteria for their manifestation in composite beams and columns [37]

cancer cells To study the effects of matrix stiffness on primary pancreatic cell proliferation, we first developed a 2D hydrogel system with stiffness (SSM) that mimic those of healthy pancreatic tissue and cancerous pancreas previously characterized. Briefly, the cancerous pancreatic tissue had a larger range of SSM (2kPa – 30kPa) and a higher average SSM than normal tissue (0.8 – 4 kPa). Consequently, to account for the variability of stiffness on cancerous tissue, our model included two groups

elbow can cause inflammation, which can spread from these joints to the tendons in your entire arm. The condition is not serious, but it can cause stiffness and mobility issues without proper care. To reduce the stiffness and pain of tennis elbow, consider using one or more of these exercises each day. Elbow Bends You may experience pain and stiffness in the evening, after a long day of work and play, but these simple bending exercises can give you some relief. Stand

Study Design: Case-Control Study Title: Presence of increased stiffness of the common carotid artery and endothelial dysfunction in severely obese children: A prospective study Journal: The Lancet Numerous epidemiological studies infer that cardiovascular complications have a directly proportional relationship with obesity in children. The study I chose however, has gone deeper by observing arterial changes as well as its relationship to cardiovascular risk in children who are obese. One of the reasons

crucial original characteristic of arthritis is joint stiffness. That is the condition which is expounded with state of no activity, decreased range or whole lack of motion in a joint. If the patient is suffering from osteoarthritis then she or he may endure from joint stiffness which may final up to half-hour after waking up. Within the of rheumatoid arthritis or systematic lupus erythematosus, which is of inflammatory forms of arthritis, the stiffness more commonly lasts for more than forty five minutes

underlying discretization of the structure such as the finite element [17] or cellular automata discretization [18]. Several authors have used direct fiber orientation angle modelling to design variable stiffness laminates. Hyer and Charrete were among the first to investigate variable stiffness laminates by aligning the fibers with the principal directions of the stress field where strength was enhanced without accounting for buckling [19]. A follow up study was conducted by Hyer and Lee to improve

Identification: Manipulate Variable: The stiffness of the spring Responding Variable: displacement from the equilibrium point Controlled Variable: The amount of friction applied (medium) The hanging mass ( 100 grams) Gravity (on earth ) Initial pull ( at the equilibrium point, untouched) Real time Hypothesis: If the stiffness of the spring increase, then the displacement

Elastagraphy shows us the stiffness of certain structures found within the body. Since malignant lesions tend to be stiffer, elastograms can aid in the diagnosis of a lesion being benign or malignant. There are two main types of elastography, Strain and Shear Wave. With the Strain technique, the transducer is manually compressed to the area of interest and the machine tracks the compressibility of the structures and then displays the various amounts of stiffness for the area. The Shear Wave

angle) of the rail ballast has effect on the stiffness the damping of the upper and the lower divisions of the rail ballast. Based on this theory, Ahlbeck et al. initiated their model (Lumped mass model) which represents only the vertical effect of the sleeper and the ballast as shown in Figure 2.1.2. This model cannot be used in high-frequency vibration[5]. Also, Ahlbeck et al. (as cited in Sun & Dhanasekar 2002)[4] find formulas for determining the stiffness value Kbl as well as the mass of the Trapezoidal
