As a result of this, the penis appears shortened in length. It was first described by Keyes Jr. E.L. in 1919. It can be associated with voiding problem and in adults, sexual issues, among others. Objective: To show that surgery can reverse celibacy induced by CP and highlight the need for an interdisciplinary approach to correction of this anomaly. Patient and Method: A thirty-one-year male patient who had a surgical release of his buried penis by two surgeons in 2019 in a private hospital. The case note was reviewed, the data obtained analyzed and the results including photographs, were presented. The patient was followed up. Result: A 10 cm length of penis and a hundred percent (100%) take of sheet of split skin graft used to resurface the denuded penis were achieved using combined spinal and epidural anesthesia. The patient, his mother and the surgeons were satisfied with the outcome. Consequently, he resolved to marry a wife after all. Conclusion: Concealed penis can now be regarded as a known cause of celibacy and surgical correction can reverse the celibate state.展开更多

They are the cost of borrowing money or the return on investment and are determined by various factors such as the supply and demand for credit, inflation expectations, and monetary policy decisions made by central banks. Changes in interest rates can have a major effect on the economy and can influence consumer spending, business investment, and overall economic growth. This makes it crucial for individuals, businesses, and policymakers to have a clear understanding of the dynamics of interest rates. Interest rates play an important role in determining the cost of borrowing money for individuals and businesses. A rise in interest rates can increase the cost of borrowing and make it more difficult for people and companies to access credit. This can lead to a decrease in consumer spending and business investment, which can slow down economic growth. On the other hand, a decrease in interest rates can make it easier for individuals and businesses to access credit and increase consumer spending and business investment, boosting economic growth. Central banks, such as the Federal Reserve in the United States, play a key role in determining interest rates by setting monetary policy. They use interest rate changes to influence the economy and reach their goals of stable prices, maximum employment, and moderate long-term interest rates. In conclusion, understanding the dynamics of interest rates is essential for making informed financial decisions and assessing the overall health of the economy. The impact of interest rates on the economy and individual financial decisions is far-reaching and long-lasting, making it a crucial topic for continued study and discussion.展开更多

As apathy is the most frequent behavioural disturbance, understanding residents’ interests is a milestone for tailored challenging interventions targeting engagement enhancement. Objective: To depict the activities interests of nursing homes residents. Method: An electronic version of the Test of Interest “TILT” which regroups 40 images of activities has been developed and adapted for the Ipad. Residents were asked to answer by yes or no to the question “are you interested by this activity”, for each activity found interesting, the patient had then to categorize it in either Work/ occupation-Personal-Leisure-Family. Population: A total of 601 residents from 19 nursing homes have completed the survey from March to May 2011. The surveyed nursing homes from the South East of France were comparable of nursing homes figures in France. Results: We interviewed 601 individuals (female, n = 484) aged 85.9 years, out of those, 56% had stayed more than one year in an institution. Nearly half of the population (45.3%) was from 80 - 89 year of age, followed by 36.1% from 90 - 99. The educational background was principally from primary school (36%) and high school (30.8%). Most of the residents were classified has having dementia (35.3%). From the 40 activities presented to each participant, “enjoying a good meal” has been found to be the most interesting activity by 83% of the population followed by “dressing up”, 75.9% and “watching TV”, 75.5%. Female participants reported more interest in place of worship, family pictures and being with grand children then males (p < 0.01). We found that the presence of “dementia” diagnosis” triggered the lack of interest compared to none demented or none cognitively impaired residents (p < 0.01). It was found that participants aged 55 - 69 were more the most interested to do video games (p < 0.05), though this may be interpreted as a positive step toward functional and cognitive rehabilitation program using virtual reality as a mean for intervention.展开更多

While making challenges for many principles and rules of international law and the traditional conception of national security, the concept does play its role in strengthening the environmental protection. However, it cannot be neglected that diflerent national interests pose an obstacle to the realization of the common interests of mankind in the envirormental protection. The article concludes that whether the concept plays its greater role in the environmental protection will depend on many factors, such as the spread of environmental awareness, the revision of the traditional conception and the balanced development of the world economy.展开更多

They play a crucial role in the flocculation, settling and dewatering of activated sludge. Furthermore, EPS also show great efficiency in binding heavy metals. So EPS are key factors influencing reduction in sludge volume and mass, as well as activity and utilization of sludge. EPS are of considerable environmental interest and hundreds of articles on EPS have been published abroad, while information on EPS in China is limited. In this paper, results of over 60 publications related to constituents and characteristics of EPS and their influences on flocculation, settling and dewatering of sludge are compiled and analyzed. Metal-binding ability of EPS is also discussed, together with a brief consideration of possible research interests in the future.展开更多

The proposed algorithm computes appropriate charging pile locations by: 1) mining user Points of Interest from social network; 2) mining parking sites of vehicle form GPS trajectories and 3) fusing the Points of Interest and parking sites together then clustering the fusions with our improved DBSCAN algorithm, whose clustering results indicates the final appropriate charging pile locations. Experimental results show that our proposed methods are more efficient than existing methods.展开更多

First, we derive a matrix integro-differential equation satisfied by the survival probabilities. Second, we analyze the asymptotic behaviors of ruin probabilities in a two-state SMRM with special claim amounts. It is shown that the asymptotic behaviors of ruin probabilities depend only on the state 2 with heavy-tailed claim amounts, not on the state 1 with exponential claim sizes.展开更多

An integro-differential equation satisfied by the expected value and a second-order differential equation for the Laplace transform of the expected value are derived. In addition, the paper will present the recursive algorithm for the joint distribution of the surplus immediately before ruin and the deficit at ruin. Finally, by the differential equation, the defective renewal equation and the explicit expression for the expected value are given in the interest-free case.展开更多
