Traffic noise in urban and regional roads and impact on the administrative facility P+30 in Prishtina

Many current problems are related to noise, which in many cases may be undesirable factorfor the daily activities and work conditions. This is especially evident in urban areas, where isa rapid growth of traffic including the number of vehicles, especially in peak time.Orientations and knowledge bases for the noise will take an important place in this paper,with the right understanding of this phenomenon.Till now in our country that is not taken into account in road and urban analyses. In this paperwe will orient the potential impact of noise in the administrative building in Pristina with P+30 floors, which is very close to the roundabout as a major source of noise. Such an outputdata, based on present measurements of the number of vehicles, made in a different specifiedperiod of time according to standards, and those elements will be interlinked with othergeometric and material parameters. All the analyses will show a result of the intensity of thenoise in dB. To analyze these parameters, intensity of the noise will be taken as the workloadof analyzed building. Also the result of unwanted intensity will be the factor for the designeddimensions and the calculation of the sound barriers in the roundabout, taking into accountthe incorporation in the environment and the urban planning of that part.The result will be presented as a 3D animation for this urban part and the impact of noise asan important factor, since we are dealing with a large concentration of administration in thisbuilding

Optimal sequential fingerprinting: Wald vs. Tardos

We study sequential collusion-resistant fingerprinting, where the fingerprinting code is generated in advance but accusations may be made between rounds, and show that in this setting both the dynamic Tardos scheme and schemes building upon Wald's sequential probability ratio test (SPRT) are asymptotically optimal. We further compare these two approaches to sequential fingerprinting, highlighting differences between the two schemes. Based on these differences, we argue that Wald's scheme should in general be preferred over the dynamic Tardos scheme, even though both schemes have their merits. As a side result, we derive an optimal sequential group testing method for the classical model, which can easily be generalized to different group testing models.Comment: 12 pages, 10 figure

Vitiligo Associated With Pegylated Interferon and Ribavirin Treatment of Patients With Chronic Hepatitis C.

Vitiligo is an autoimmune disease characterized by depigmented patches and macules. It is associated with many autoimmune diseases, the most common of which is thyroid diseases. The association between Interferon (IFN) therapy and vitiligo is rarely reported in the literature, despite its common usage in many diseases particularly hepatitis C viral infection (HCV). We report four cases of vitiligo that appeared after treating HCV with pegylated IFN

Operator representation and logistic extension of elementary cellular automata

We redefine the transition function of elementary cellular automata (ECA) in terms of discrete operators. The operator representation provides a clear hint about the way systems behave both at the local and the global scale. We show that mirror and complementary symmetric rules are connected to each other via simple operator transformations. It is possible to decouple the representation into two pairs of operators which are used to construct a periodic table of ECA that maps all unique rules in such a way that rules having similar behavior are clustered together. Finally, the operator representation is used to implement a generalized logistic extension to ECA. Here a single tuning parameter scales the pace with which operators iterate the rules. We show that, as this parameter is tuned, many rules of ECA undergo multiple phase transitions between periodic, locally chaotic, chaotic and complex (Class 4) behavior

Esophageal variceal ligation in the secondary prevention of variceal bleeding: Result of long term follow-up

Introduction: Long-term outcome of patients after band ligation have been poorly defined. Therefore, we conducted a long-term follow-up study to delineate the outcome of ligation in patients with portal hypertension in the Hassan II university hospital, Fes, Morocco. Methods: Over 118 months patients treated by endoscopic variceal ligation were received regular follow- up and detailed clinical assessment of at least 24 months.Results: One hundred twenty five patients were followed up for a mean of 31 months (range 12-107 months). Obliteration of the varices was achieved in 89.6 % (N=112) of patients, with 3 +/-1.99 (range 1-8) endoscopy sessions over a period of 14+/-6.8 weeks (range 3-28). The percentage of variceal recurrence during follow-up after ligation was 20.5 % (N=23). Recurrence were observed in a mean of 22 months +/- 7.3 (range 3-48). Bleeding rate from recurrent varices was 30.4 % (7/23). Rebleeding from esophageal ulcers occurred in 5.6 % (7/125) of patients. Portal hypertensive gastropathy before and after eradication of varices was 17.6% (N=22) and 44.6% (N=50) respectively; p< 0.05. Fundal gastric varices was 30.4% (N=38) and 35.7% (N=40) before and after eradication of varices respectively; p> 0.05. The overall mortality was 4 % (N=5).Conclusion: Band ligation was an effective technical approach for variceal obliteration with low rates of variceal recurrence, rebleeding and development of gastric varices. Furthermore, it was associated with frequent development of portal hypertensive gastropathy.Key words: Variceal hemorrhage, endoscopic band ligation, liver cirrhosis, complication of band ligation, esophageal varices, secondary preventio
