General guidelines for screening for keratoconus: 1. Anterior and posterior elevation maps (Demirbas et al., 1998): In the anterior elevation map differences between the best fit sphere and the corneal contour of less than +12 μm are considered normal, between +12 μm and +15μm are suspicious, and more than +15 μm are typically indicative of keratoconus. Similar numbers about 5 μm higher apply to posterior elevation maps. 2. Anterior curvature map (Tomidokoro et al., 2000): The steepening of the cornea, irregular astigmatism, inferior steepening (I-S difference), location of steepest point and the thinnest point on the cornea may help in the diagnosis of keratoconus.
2) Levator veli palatini muscle: Adequate LVP movement in 59% and inadequate in 41%. 1) Closure: 71.8% had a central closure and 28% had a lateral closure. 28% of the cases had < 50% closure; 37.5% had 50-80% closure whereas 34% had > 80% closure. B) Perceptual assessment of articulation errors and resonance problems 1) Articulation:; Fricatives are more afftected (65.63%) followed by affricates and stops; the most commonly seen error was distortions( 56.25%) followed by omissions and substitutions. Reduced intra oral pressure was seen in 90.63% of the cases.
Fig 3shows that, modeled curve fit well to the experimental data. Therefore this model could be used as an efficient method for the prediction of degradation of organic pollutant by UV/ TiO2 process with different pollutant dosages. Evaluation of L-H model The plot of 1/kapp versus [PNP]0 gives a straight line confirming that the L-H model is applicable for the present degradation system, which is shown in Fig 4. Figure 4: Evaluation of L-H kinetic model The values of kc and KLH calculated from the slope and intercept of the plot shown in Fig 4 were found to be 2.35x10-6molL-1min-1 and 7664.48Lmol-1 respectively. Conclusion The Photocatalytic degradation of PNP has been carried out by UV/ TiO2 process.
This can occur on overhead lines or in substations where the flashover arc of the faulted phase spreads to other healthy phases (Nasser 2008). In the course of this work we investigated only a Symmetrical Three Phase (L-L-L) Fault, since roughly 5% of all faults involve all three phases and they are the most severe. For a three- phase fault, the fault impedance is zero and the faulted bus has the same impedance as the ground. (Prabha
The lowest accounts payable has the industry under the number and that is software development (1.2%) and number 9 Pharmaceuticals industry (1.3%). Current liabilities of commercial banking are 78.4%, and that would be the highest of all industries. If we look at the receivables collection the same number of 23 has the Internet development and electric utility. The lowest ROA have the commercial banking, electric utility and wholesale food distribution. The highest ROA has the software development.
However, this paper neglects the other causes for cascade e.g voltage instability, variations in frequency etc. The paper suggests that Branching Process gives an accurate result even for shorter number of simulations. The average propagation of simulated load shed is estimated in  and then the initial load shed is propagated with discrete and continuous Branching Process. The estimated load shed data is validated using the OPA and the TRELSS simulators. In , it has been proposed that Branching Process model matches the distribution of number of cascading line outages and load shed simulated by two enhanced versions of the OPA simulation on the IEEE 118-bus system and the North-east Power Grid of China (NPGC).
• Stage III severe OSMF: Burning sensation is very severe patient unable to do day-to-day work, more than 66% reduction in the mouth opening, cheek flexibility and tongue protrusion. Tongue may appear fixed. Ulcerative lesions may appear on the cheek, thick palpable bands and lymphadenopathy bilaterally evident. Lai Dr (1995) divided OSMF based on the inter-incisal distance as follows: • Group A: >35 mm • Group B: Between 30 and 35 mm • Group C: Between 20 and 30
This is characterised avoiding dental treatments and can be recognised with following criteria, Such as an exposure to the feared stimulus, which may take the form of a panic attack? Some other studies shows that 70% to 80% of different age patients undergoes through different kind of dental treatment anxiety before dentistry operating procedures. Which is cause of unsuccessful treatments and dissatisfaction of patients.it also might cause prevent further future visits to dentists. Many past researches on dental treatment anxiety in third world countries have said that patients usually avoid dentistry treatment procedures because of dental fear cause in poor oral hygiene.dental anxiety become one the top worldwide ranking problem. Dental anxiety is ranked 9th among the intense fear and 4th among the common fears.in most third world countries access to dentistry treatment is very limited due to high cost of treatments.
Chapter-4 CONTROLLERS 4.1 INTRODUCTION The topic discusses principles of converters used for multiple stage design of LED driver. This topic also presents the functions of each component in the design circuit and the operation of each one. 4.2 CONTROLLED CONVERTER Switching regulators are preferable than linear regulators owing to the higher efficiency. The utmost interesting feature of switching regulator is the conversion of energy stored in the inductor .The energy stored may be utilized for increasing the output voltage(Boost), reducing the output voltage(Buck) or even it can used to provide isolation by connecting a transformer. Secondly, the losses due to transmission is less.
