Extensible Authentication Protocol Vulnerabilities and Improvements

Extensible Authentication Protocol(EAP) is a widely used security protocol for Wireless networks around the world. The project examines different security issues with the EAP based protocols, the family of security protocols for Wireless LAN. The project discovers an attack on the subscriber identity module(SIM) based extension of EAP. The attack is a Denial-of-Service attack that exploits the error handling mechanism in EAP protocols. The project further proposes countermeasures for detection and a defense against the discovered attack. The discovered attack can be prevented by changing the protocol to delay the processing of protocol error messages

The Employment of Women Professionals in Organizational Practice

Women in the workforce earning wages or a salary are part of a modern phenomenon, one that developed at the same time as the growth of paid employment for men, but women have been challenged by inequality in the workforce. Restrictions on women's access to and participation in the workforce include the wage gap, the glass ceiling, inequities most identified with industrialized nations with nominal equal opportunity laws; legal and cultural restrictions on access to education and jobs, inequities most identified with developing nations; and unequal access to capital, variable but identified as a difficulty in both industrialized and developing nations This paper covers the various aspects of scope of women at work place, gender inequality at work place and possible solutions to it

Steroid Pulse Therapy in the Management of Neuro-psychiatric Manifestations in an Atypical Presentation of Typhoid Fever

The Typhoid fever often presents with a variety of clinical symptoms and numerous systemic complications. Neurological complications of enteric fever are relatively insidious and rare and many times late and often undiagnosed complication of typhoid fever which can change the course of illness. This is a case of blood culture-proven typhoid fever with neuropsychiatric manifestations responded well with appropriate antibiotics and steroid pulse therapy (1 gram Methylprednisolone for 3 days)

An axisymmetric interfacial tracking model for melting-vaporization-resolidification in a thin metal film irradiated by pico to femtosecond pulse lasers

The entire thesis text is included in the research.pdf file; the official abstract appears in the short.pdf file; a non-technical public abstract appears in the public.pdf file.Title from PDF of title page (University of Missouri--Columbia, viewed on November 11, 2010).Thesis advisor: Dr. Jinn-Kuen Chen, Dr. Yuwen Zhang, Thesis Supervisors.M. S. University of Missouri--Columbia 2010.A two dimensional axisymmetric, interfacial tracking method is developed to model rapid melting and solidification of a free standing metal film subjected to an ultra-short laser pulse. Finite volume method is employed to solve the coupled electron and lattice heat conduction equations together with the equations for ultrafast solid-liquid phase transformation, to calculate the location of solid-liquid interface and the temperature distribution in the metal film. The interfacial velocities, both melting and resolidification, in the ultra-fast phase change process are obtained by considering interfacial energy balance and the nucleation dynamics. Both the electron and lattice temperature in the metal film irradiated by Gaussian laser beams are computed and presented along the cylindrical coordinates. The effect of laser fluences and characteristic radii on melting and resolidification are also investigated. A numerical procedure to analyze the vaporization of metal when interacts with ultrashort laser pulse is also developed. The temperature dependent thermal characteristics as well as electron-lattice coupling factor have been considered. An iterative procedure based on energy balance and gas kinetics law is implied to track the axisymmetric liquid-vapor interface, which in turn is utilized to obtain the material removal rate.Includes bibliographical reference

Premature ovarian failure incidence, risk factors and its relation to BMI and infertility

Background: Premature ovarian failure (POF) is cessation in the normal functioning of the ovaries in women younger than age 40 years. It is estimated to affect1% of women younger than 40 years and 0.1% of those under 30 years. Premature ovarian failure is a common cause of infertility in women.Methods: Patient attending outpatient Department of Obstetrics and Gynecology with age less than 40 years and complaint of menstrual disturbances, symptoms of menopause were enrolled for the study for duration of 1year. This study is planned to calculate the incidence, risk factors, relation to BMI and infertility in patients attending outpatient department at Geetanjali medical college and hospital, Udaipur for all enrolled patient coming with complaints of menstrual disturbances. FSH levels were send for all the patients and those with FSH level more than 20 at day 2/3 for menstruating women and random FSH level for amenorrhea patient more than 20 were classified in to study group and all those women with FSH less than 20 are taken as control group.Results: Present study strongly suggests that simple laboratory test FSH and symptoms of missed and irregularity of menstrual cycle help in early and prompt diagnosis of premature ovarian failure. And early diagnosis helps in avoiding unnecessary medications and helps in improving long term morbidity.Conclusions: Disturbances in menstrual cycle like amenorrhea and infrequent cycles are the symptoms which are associated with premature ovarian failure after ruling out pregnancy and other hormonal and structural causes

Asymptomatic bacteriuria in pregnancy and its relation to perinatal outcome

Background: Asymptomatic bacteriuria is one of the cause for adverse perinatal outcome. Pregnant women are at high risk for UTIs. Women exposed to antepartum urinary tract infection had increased incidence of delivering infants with low birth weights, premature infants, preterm infants with low birth weights, than those who were not exposed. Women exposed to antepartum urinary tract infection were also more likely to experience premature labor, hypertension or preeclampsia and anemia.Methods: Antenatal women attending Geetanjali medical college and hospital, Udaipur, OPD department were screened for asymptomatic bacteriuria and followed up till delivery. Two groups were made one with asymptomatic bacteriuria positive and treated and other with non-asymptomatic bacteriuria patients. Both groups were followed uptill delivery to note their adverse perinatal outcomes. Odds ratios (OR’s) and 95% test based confidence intervals (CI’s) were computed between two groups to note their perinatal and maternal outcomes.Results: Prevalence of asymptomatic bacteriuria was 12.27%. Mean gestational age at which women presented was 14-26 weeks. No incidence of pyelonephritis was found. No significant adverse perinatal outcome was noted amongst patients treated for asymptomatic bacteriuria.Conclusions: Early screening and treatment of ASB when implemented helps in reducing adverse maternal outcome
