    AbstractTranslucent Makrofol¼ DE 7-2 polycarbonate samples are thermally-annealed at 200°C for different durations in the air. UV–Vis spectra of the thermally-annealed Makrofol¼ DE 7-2 were measured. The results reveal that the light absorbance by thermally-annealed Makrofol¼ DE 7-2 is significantly minimized which enhances the visualization of the charged particle track registered on it. Both direct and indirect band gaps show pronounced stability over all thermal annealing durations; the same behavior was observed to Urbach’s energy and the number of carbon atoms per cluster where no reasonable alteration was observed. The thermally-annealed Makrofol¼ DE 7-2 was irradiated with 3MeV alpha particles and etched for different durations in 75% 6N KOH+25% C2H5OH at 50°C. Alpha particle track diameter is found to be linearly correlated with the etching time up to 3h before the Bragg peak. The chemical etching efficiency of alpha particle tracks ranges from 0.22 to 0.26. The current new findings indicate the possibility to improve the optical properties of translucent Makrofol¼ DE 7-2 by a thermal annealing for its utilization in charged particle registration

    Get PDF
    Nowadays, the demand for energy and fossil fuels has widely increased as a result of the continuous growth of the population. However, the continued use of traditional fuels as the primary source of energy has resulted in various environmental challenges related to climate change and global warming. This has prompted researchers to look for more eco-friendly and sustainable fuel alternatives with a minimal amount of engine modification and emission treatment techniques. Amongst the suggested alternative fuels, biofuels, biofuel/diesel blends, and the incorporation of nanoparticles into fuels. The nanoparticle diesel additives played a vital role in increasing engine performance as well as retarding harmful emissions such as nitrogen oxides (NOx), carbon monoxide (CO), unburned hydrocarbon (UHC), and particulate matter (PM). Metal-oxides nanoadditive such as aluminum oxide (Al2O3), ceric oxide (CeO2), and titanium dioxide (TiO2) act as oxygen catalysts and promote proper mixing of fuel and air, resulting in more efficient combustion and decreased emissions. The incorporation of nanometal-based additives, including iron (Fe), copper (Cu), and aluminum (Al) accelerated the fuel evaporation rate and increased the probability of fuel ignition. Carbon-based nanoparticles such as carbon nanotubes (CNTs), graphene nanoplatelets (GNPs), and graphene oxide (GO) are promising fuel nanoadditives owing to their metal-free composition. In addition, carbon-based additives enhanced the thermal conductivity of fuel and increased active sites available for chemical reactions, which led to improved engine performance

    Background/Purpose: One stage urethroplasty with parameatal foreskin flap (OUPF) applicable to all types of hypospadias was first described by Tomohiko Koyanagi, however high complication rates were reported.The aim of this study is to analyze the results of a modification of the Koyanagi technique as a one-stage repair of proximal hypospadias. Patients and Methods: During the period of from March 2008 to March 2009, 30 patients underwent treatment of proximal hypospadias using the modified Koyanagi technique. Patient age at the time of surgery ranged from 6 to 24 months. In all cases, the urethral opening was at or just proximal to the penoscrotal junction. Follow up ranged from 3 months to 1 year. Results: Primary success occurred in 27 cases (90%) with accepted cosmetic appearance. Complications occurred in 3 cases (10%). Urethrocutaneous fistula occurred in 2 cases (6.7%). Meatal recession occurred in 1 case (3.3%). There was no incidence of meatal stenosis, urethral stricture, residual chordee or complete flap necrosis. Conclusion: The modified technique permits one-stage repair of proximal hypospadias with low complication rates. Keywords: Hypospadias, Koyanagi, One stage urethroplasty

    Determination of Noise Caused by Ventilated Brake Disc with Respect to the Rib Shape and Material Properties Using Taguchi Method

    Get PDF
    Ventilated brake discs may have various configurations of ribs and can be manufactured from different materials. In order to improve the performance in extreme exploitation conditions, it is necessary that they heat up and wear as little as possible, and that they have good heat dissipation capacity and generate low noise. To achieve this, optimization of the influential parameters is required. In this study, the optimization and the analysis of the frequency value were made on the basis of the influential parameters, such as brake disc vane shape, density, Young’s modulus, and Poisson\u27s coefficient. A numerical investigation was conducted using the ANSYS software package in the MODAL module. In order to better understand which parameter has the greatest influence on the noise formation, the Taguchi method was applied. By applying the Analysis of Variance – ANOVA, the influence of each parameter on frequency, expressed as a percentage, was determined. The obtained results show that the most influential parameter is the shape of the ribs (90.82%), followed by Young’s modulus (8.26%) and density (0.89%)

    Get PDF
    Background/purpose Persistent hyperinsulinemic hypoglycemia of infancy (PHHI) is the most common cause of persistent hypoglycemia in infancy with consequences such as seizures and brain damage. Treatment that prevents the occurrence of these sequele is essential. When medical therapy fails or complications are anticipated, early pancreatectomy is recommended to maintain euglycemia. The aim of this study was short-term evaluation of near-total pancreatectomy for PHHI after failure of medical treatment in patients in Mansoura, Egypt.Patients and methods During May 2002 to May 2010, 33 patients suffering from persistent hyperinsulinemic hypoglycemia were admitted to Mansoura university child hospital. Twenty patients responded to medical treatment and 13 patients (eight girls and five boys) were treated by near-total (90–95%) pancreatectomy after failure of medical treatment. Their ages at the time of surgery ranged from 20 days to 27 months. Only patients who were surgically managed were included in this study. All of them suffered from symptoms of PHHI: thermoregulatory problems in five cases, tremors in five cases, seizures in three, irritability in five, respiratory distress in eight, apnea in four, hypotonia in four, lethargy in five, and feeding difficulty in four cases. All cases were diagnosed following strict criteria that included bouts of hypoglycemia without acidosis coinciding with increased insulin level. Follow-up ranged from 3 months to 8 years.Results Primary success occurred in two cases (15%); four more cases (31%) developed temporary diabetes mellitus, and one case (8%) had a temporary pancreatic fistula. Eventually, total cure occurred in seven cases (54%); six cases (46%) developed a variety of complications; and persistent hypoglycemia was seen in two. Persistent diabetes mellitus was observed in three patients, developmental delay in one, and persistent neurological deficit in two patients; there was one case of mortality.Conclusion Near-total (90–95%) pancreatectomy is a suitable procedure for treatment of nesidioblastosis not responding to medical treatment and should be performed as early as possible. Keywords: Mansoura, near-total pancreatectomy, persistent hyperinsulinemic hypoglycemi
