    A normal voice is judged according to whether the pitch, loudness, quality are adequate for communication and suit a particular person. A person may use a pitch which is too high or too deep, intensity that is too loud or too soft, or voice quality may be too hoarse, breathy or Harsh. Hoarseness of voice may be defined as a quality of voice, which is rough, grating, harsh more or less discordant and lower in pitch than normal voice: Hoarseness is purely a relative term. Setting the vocal cords in vibration by an air column is purely mechanical process. So anything that impairs the perfect working of this Mechanism produces voice disorder. Voice disorder is one of the important and major indicator of diseases of throat and nose. The present study titled "Analysis of voice disorders by Dr.Speech and Electroglottography", is mainly aimed at voice assessment inclusive of Hoarse voice, Harsh voice, Breathy voice, vocal fold regularity and Glottal closure time and etiopathology of voice disorder. Fifty cases randomly collected presented with change of voice of various etiology were at the Upgraded Institute Of Oto - Rhino Laryngology, Govt. General Hospital, Chennai, attached to Madras Medical College, during the period of study from October 2004 to September 2005 A.D. Dr.Speech is very useful to identify voice characteristics of different vocal cord pathologies and with in depth study of Dr.Speech and Electroglottography, it may be possible to approximate diagnosis just by analysing the voice assessment and EGG recordings. It is also useful in voice therapy to restore the voice in cases with non - malignant voice disorders, before and after medical and surgical management

Various biochemical estimations like glucose, cholesterol. Triglycerides, LDL and HDL levels and antioxidant estimations like TBARS SOD, CAT, and GSH were estimated in two different doses of Anisomeles malabarica Linn (100 and 200mg/kg p.o.) and then compared with the standard and induced compound. Anisomeles malabarica Linn at a dose of 100mg/kg and 200mg/kg prevented the development of hyperglycemia, hypercholesteremia and hypertriglyceridemia in dexamethasone induced insulin resistance models. Oral administration of Anisomeles malabarica Linn 100mg/kg and 200mg/kg reduces serum glucose, triglyceride, total cholesterols and LDL concentration and improve the concentration of HDL in dexamethasone administered rats. The lignin Anisomeles malabarica Linn showed significant anti-diabetic effect in rats after oral administration. The present study demonstrated that Anisomeles malabarica Linn could be useful in Management of diabetes associated with abnormalities in lipid profiles. Further study need to isolate, identify the active compounds and find out the possible mechanism of actions

    Exploring Enterprise Systems Adoption in Bahrain

    Enterprise Systems (ES) are multi-million dollar systems that are adopted by organizations to improve their operations. However, implementation of these systems is not straightforward and challenging, as it requires changes in work practices and business practices. These systems become more complicated for organizations in developing countries as they are based on western assumptions. While there are studies that examine ES adoption in developing countries, there are still conflicting results. In this study, we examine the critical success factors in different stages of ES implementation using multiple case studies of three organizations in Bahrain. The findings show that there are different factors important in different stages of implementation. Some of these factors are important throughout the implementation and others are important in particular phases. This research has important implications for research and practice

    Islamic credit card (ICC) has been widely used for personal consumption. The use of ICC is gaining prominence as an alternative to conventional credit card as the concept and operations are permissible by the shariah. The paper aims to determine factors influencing intention to use ICC based on three variables namely benefits, fair charges and religious motivation. A quantitative methodology was conducted via a survey of 102 respondents in the state of Selangor. The results indicated that benefits and religious motivations have significant influence on the intention to use Islamic credit cards. Hence, practitioners should incorporate the two factors in their marketing efforts to promote ICC. The academician can benefit by conducting further research on this eminence body of knowledge

    This manuscript explores the flow features of the Modified Cross Model in a channel with symmetric trapezoidal cavities in the presence of a circular obstacle. The non-dimensional governing equations and model for different parameters are evaluated via a Galerkin Finite Element Method The system of non-linear algebraic equations is computed by adopting the Newton method. A space involving the quadratic polynomials (P2) has been selected to compute for the velocity profile while the pressure profile is approximated by a linear (P1) finite element space of functions. Simulations are performed for a wide range of physical parameters such as modified parameter (from 0.0 to 0.5), power-law index (from 0.5 to 1.5), relaxation parameter (from 1 to 3), and Reynolds number (from 10 to 40). For the case of a modified parameter (b) and relaxation parameter (λ), it is observed that the drag coefficient (CD) shows an increasing trend while the lift coefficient (CL) is changing sign at lower values of (λ), and then becomes positive at λ=3

    A Single DC Source Nine-Level Switched-Capacitor Boost Inverter Topology with Reduced Switch Count

    Get PDF
    This paper presents a new boost inverter topology with nine level output voltage waveform using a single dc source and two switched capacitors. The capacitor voltages are self-balancing and thus is devoid of any sensors and auxiliary circuitry. The output voltage is twice higher than the input voltage, which eliminates the need for an input dc boost converter especially when the inverter is powered from a renewable source. The merits of the proposed topology in terms of the number of devices and cost are highlighted by comparing the recent and conventional inverter topologies. In addition to this, the total voltage stress of the proposed topology is lower and have a maximum efficiency of 98.25%. The operation and dynamic performance of the proposed topology have been simulated using PLECS software and are validated using an experimental setup considering a different dynamic operation.This work was supported in part by the Scientific Research Deanship, Taif University, Saudi Arabia, under Grant 1-439 - 6072.Scopu

    AIMS/INTRODUCTION:This study determined the prevalence and risk factors for DPN and pDPN in patients with type 2 diabetes (T2D) in primary health care (PHC) and secondary health care (SHC) in Qatar. MATERIALS AND METHODS:This is a cross-sectional multi-center study. Adults with T2D were randomly enrolled from four PHC centres and two Diabetes Centres in SHC in Qatar. Subjects underwent assessment of clinical and metabolic parameters, DPN and pDPN. RESULTS:1,386 subjects with T2D (297 from PHC and 1,089 from SHC) were recruited. The prevalence of DPN (14.8% vs 23.9%, P=0.001) and pDPN (18.1% vs 37.5%, P<0.0001) was significantly lower in PHC compared to SHC, whilst those with DPN at high risk for DFU (31.8% vs 40.0%, P=0.3) was comparable. The prevalence of undiagnosed DPN (79.5% vs 82.3%, P=0.66) was comparably high but undiagnosed pDPN (24.1% vs 71.5%, P<0.0001) was lower in PHC compared to SHC. The odds of DPN and pDPN increased with age and diabetes duration and DPN increased with poor glycemic control, hyperlipidemia and hypertension, whilst pDPN increased with obesity and reduced physical activity. CONCLUSIONS:The prevalence of DPN and pDPN in T2D is lower in PHC compared to SHC and is attributed to overall better control of risk factors and referral bias due to patients with poorly managed complications being referred to SHC. However, ~80% of patients had not been previously diagnosed with DPN in PHC and SHC. Further, we identify a number of modifiable risk factors for PDN and pDPN
