Exchange characteristics of an anthropogenically modified lagoon: an Eulerian-Lagrangian modeling case study with an emphasis on the number of particles

The transport pathways and exchange characteristics of the Kamil Abdüş Lagoon in Istanbul, Turkey, are simulated using a finite element model with a Lagrangian particle tracking module. The lagoon is in the process of being reconfigured. The simulations are performed using a draft configuration. The effect of winds and the number of particles on the e-folding time is simulated. Results show that the lagoon is strongly dominated by winds with a correlation coefficient of 0.897 between the wind and residual current magnitudes. The lagoon e-folds in 9.1 days under realistic winds and in 14.3 days when there is no wind with confidence levels of 5%. The Lagrangian study uses six simulations with particle numbers ranging between 65073 and 2730486. A methodology based on confidence levels is proposed. It is observed that approximately 784 000 particles are necessary to obtain 5% level of confidence. With a problematic history and new planning options, the lagoon has a potential to be used as an example setting, all-field study ground for anthropogenically engineered coastal ecosystems

Increased P-wave dispersion in patients with newly diagnosed lichen planus

OBJECTIVE: Lichen planus is a chronic inflammatory autoimmune mucocutaneous disease. Recent research has emphasized the strong association between inflammation and both P-wave dispersion and dyslipidemia. The difference between the maximum and minimum P-wave durations on an electrocardiogram is defined as P-wave dispersion. The prolongation of P-wave dispersion has been demonstrated to be an independent risk factor for developing atrial fibrillation. The aim of this study was to investigate P-wave dispersion in patients with lichen planus. METHODS: Fifty-eight patients with lichen planus and 37 age- and gender-matched healthy controls were included in this study. We obtained electrocardiographic recordings from all participants and used them to calculate the P-wave variables. We also assessed the levels of highly sensitive C-reactive protein, which is an inflammatory marker, and the lipid levels for each group. The results were reported as the means ± standard deviations and percentages. RESULTS: The P-wave dispersion was significantly higher in lichen planus patients than in the control group. Additionally, highly sensitive C-reactive protein, LDL cholesterol, and triglyceride levels were significantly higher in lichen planus patients compared to the controls. There was a significant positive correlation between highly sensitive C-reactive protein and P-wave dispersion (r = 0.549,

Systematic approach to a dysmorphic child Dismorfik çocuǧa yaklaşim

Genetic disorders have a major effect on public health, as shown by large epidemiologic studies. The current data indicate that genetic factors contribute to almost two thirds of the conditions requiring admission to a children's hospital. Early identification of the genetic nature of a given condition may provide resources for better care to these individuals. Therefore it is crucial to establish a systematic approach to a dysmorphic, or malformed child. This article presents such a general approach

Buzağılarda uzun kemik kırıklarının Ilızarov tekniği ile sağaltım olanaklarının araştırlıması

Bu çalışma Ankara Üniversitesi Veteriner Fakültesi Ortopedi ve Travmatoloji Bilim Dalı Kliniği'ne getirilen 3 adet buzağı üzerinde gerçekleştirildi. 2 olguda parçalı tibia kırığı, bir olguda parçalı metacarpus kırığı saptandı. Olguların belirlenen kırıkları genel anestezi altında Iliz.arov'un sirküler eksternal fikz.asyon sistemi ile sağaltıldılar. Birinci olguda (Olgu no: 1) 150 mm çaplı 3 halkalı, 3 rodlu; 2. olguda 150 mm çaplı proksimal 1. halka 1/2 olmaküzere 3 halkalı, 3 rodlu ve 3. olguda proksimal halka 1/2 olmak üzere ve buna hibrid fikz.asyon amacı ile iki adet 4 numara Schanz vidası ile 3 halkalı, 3 rodlu tliz.arov'un sirküler eksternal fıkzasyon sistemi uygulandı. Olguların apareyi çok iyi talere ettikleri ve reaksiyon göstermedikleri belirlendi. Olgular ekstremitelerini ilk kullanmaya sırasıyla postoperatif 2, 6 ve 5. günlerde başlarken, vücut ağırlıklarını ise postoperatif sırasıyla 15, 20 ve 17. günlerde ekstremitelerine vermeye başladılar. Radyografik takipler sonucunda kırık konsolüdasyonunun olgularda postoperatif sırasıyla 45, 35 ve 48. günlerde tamamlandığı izlendi. Olgulardan aparey sırasıyla postoperatif 60, 45 ve 60. günlerde anestezi uygulanmadan çıkarıldı. Bir olguda (Olgu no:3) pin dibi enfeksiyonu izlenirken, başka bir problem olmadan tüm olgularda tam fonksiyonel iyileşme sağlandı. Sonuç olarak Türkiye'de ilk kez buzağıların uzun kemik kırıklarının sağaltımında Iliz.arov'un sirküler eksternal fikzasyon sistemi kullanıldı ve alınan sonuçlara dayanarak bu sistemin buzağılarda güvenle kullanılabilecek bir sistem olduğu kanısına varıld
