Delayed Diagnosis of an Intraurethral Foreign Body Causing Urosepsis and Penile Necrosis

Cases of self-inserted foreign bodies in the male urethra and urinary bladder are unusual. In most cases, the type of foreign body can be identified by taking a history or from radiological findings; sometimes, however, it is difficult to identify the foreign body because of decreased mental capacity of the patient or unknown radiological characteristics of the foreign body. We experienced a chronic alcoholic patient with septicemia and penile necrosis in whom a fragment of mirror glass had passed through the urethra into the bladder. The glass, 2 cm in length and 0.7 cm in diameter, was detected by cystoscopy and was removed by using a resectosope

Urodynamic and Histological Changes in a Sterile Rabbit Vesicoureteral Reflux Model

This study aimed to investigate pressure changes of renal pelvis and histological change of kidneys in a surgically induced sterile rabbit vesicoureteral reflux (VUR) model. Five rabbits served as a control group, 7 as the sham-operated group, and 8 served as the VUR group. Three weeks later, urodynamic studies were performed, and histological examinations evaluated degree of inflammation, fibrosis, and tubular damage in the kidneys. At a low infusion rate, renal pelvic pressure in the VUR group was stable until late filling phase and then increased slightly. At a high infusion rate, the renal pelvic pressures of the sham-operated and control groups were stable until late filling phase and then increased slightly, whereas the renal pelvic pressure in the VUR group steadily increased from mid filling phase. Focal thinning of the tubular epithelium and interstitial widening were observed in certain cortical areas of refluxing kidneys, without inflammatory cell infiltration. Obvious changes in the mean diameters of distal tubules and extracellular matrix volume fractions were observed in two highly refluxing kidneys. High pressure reflux with bladder instability may result in renal cortical changes

The Socio-Political Dynamics of Corruption: An Analysis on the EU Countries

WOS: 000290501300007The roots of corruption are grounded in a country's economic, political, legal, social and cultural history. The aim of this paper is to empirically test a model that associates non-economic factors such as democracy, law system, education, ethnic fractionalization and Protestant tradition with average corruption rates in a cross-section of 25 Europe countries between the years 2004 and 2007. The empirical results of the study found that democracy, law system, education and Protestant tradition were statistically significant determinants of corruption. In this respect, a country's transition from weak democracy and powerful democracy reduces corruption. An effective law system and education system also decrease corruption. Moreover, it was found that corruption was low in countries with the dominant Protestant tradition. However, in this study, ethnic fractionalization was not found to be statistically significant determinant of corruption

Correlation analysis of dynamic spectral phonocardiogram with electrocardiogram as a means of assessing the heart ailment

IEEEProceedings of the 1995 IEEE Instrumentation and Measurement Technology Conference --23 April 1995 through 26 April 1995 -- Naltham, MA, USA --This paper reports the development of a PC-based system performing spectral estimation and correlation analysis of phonocardiogram and electrocardiogram as to establish a basis for making cardiovascular diagnosis. Keeping in view of simplicity in hardware requirement, a PC is converted into a real-time PC by adding an I/O card to the printer port. The heart sound signal picked up from a high sensitive microphone and the ECG signal taken from the electrodes attached to the patient are digitized, read in to the PC and saved as data files. From these data files, power spectral densities are estimated accordingly. Then, the PSD of the patient's heart sound is cross correlated with the PSD of the stored normal heart sound and also with the PSD of the ECG. The power spectral densities and the cross correlation results are presented simultaneously as 3-D window display in the PC screen. The simultaneous display of all these information would help in simplifying the diagnosis process

Sizing of a solar-wind hybrid electric vehicle charging station by using HOMER software

Canbaz, Celal Hakan/0000-0001-8312-6941WOS:000595857000001Although, fossil fuels are still the main source that used to balance the global demand/supply dynamics of energy; most countries have embarked on a quest to reach a solution and started changing their direction from fossil resources (especially oil and gas) to other resources by creating new opportunities with a focus meeting the increasing energy demand by reducing it via energy efficiency. "Transportation" is one of the biggest items of global energy consumption with 24% usage percentage and most of this amount is supplied by conventional energy resources. However, worldwide supporting policies and regulations are positively affected the starting period of environment-friendly use of energy resources. It expedited the process of new technological developments that minimize waste, lower the level of air pollution caused by fossil fuel-powered internal combustion engines, conserve forests and decrease the emissions of greenhouse gases. Worldwide extension of "Electric Vehicle Development and Production" is one of the main concern of these regulations. However, increasing the number of electric vehicles also brings sustainability problems such as; supplying the electricity from renewable resources in an efficient and sustainable way, handling the electricity load on the grid, and establishment of new charging stations. Therefore, in this study a wind solar hybrid energy charging station designed and optimized via HOMER software. The sizing methodology is suitable to apply anywhere around the worldwide. The optimal solution for the hybrid system consists of 44.4% wind energy and 55.6% solar energy and the annual electricity production is 843150 kWh with the 0.064 $/kWh production cost.
