CMB Anisotropy Induced by a Moving Straight Cosmic String

We showed that the part of strings could be detected by optical method is only 20% from the total available amount of such objects, therefore the gravitational lensing method has to be "completed" by CMB one. We found the general structure of the CMB anisotropy generated by a cosmic string for simple model of straight string moving with constant velocity. For strings with deficit angle 1-2 arcsec the amplitude of generated anisotropy has to be 15-30 muK (the corresponding string linear density is (G mu) ~ 10^{-7} and energy is GUT one, 10^{15} GeV). To use both radio and optical methods the deficit angle has to be from 0.1 arcsec to 5-6 arcsec. If cosmic string can be detected by optical method, the length of corresponding brightness spot of anisotropy has to be no less than 100 degrees.Comment: 6 pages, 1 Postscript figure, will be published in proceedings of QUARKS-2008, 15th International Seminar on High Energy Physics, Sergiev Posad, Russia, 23-29 May, 200

EXPERIENCE OF USING OF OCTREOTIDE-DEPOT IN PREVENTION OF THE DEVELOPMENT AND TREATMENT OF EXTERNAL PANCREATIC FISTULAS OF DIFFERENT GENESIS

In the period from 2011 till 2012 the Otcreotide-depot was used by the authors in treatment of 34 patients. The patients were divided into two groups: the first group — the prevention of development and the second group — the treatment of external pancreatic fistulas. Ocreotide-depot was applied in 17 patient of the first group: as part of the complex therapy of severe pancreatitis in 4 patients and after pacreaticoduodenectomy in 13 patients. Ocreotide-depot was used in 17 patients of the second group: 7 cases of patients after different types of pancreatic resections and after external drainage of pancreatic cysts in 10 patients. The positive effect of using the drug was obtained in 30 patients (88,25%): the cases of preventive application of drug in 17 patients and during the treatment of external pancreatic fistulas in 13 patients. The preventive and therapeutic usage of Ocreotide-depot facilitated an uncomplicated postoperative period in 13 cases and the healing of the external pancreatic fistulas in terms from 5 till 7 days in 13 patients. The application of Ocreotide-depot could be recommended as a preventive measure against the incompetence of pancreaticojejunoanastomosis after pancreaticoduodenectomy in complex therapy of severe pancreatitis and also in treatment of external pancreatic fistulas after pancreaticoduodenectomy and percutaneous drainage of postnecrotic pseudocysts

Dendrochronology and Radiocarbon Dating Methods in Archaeological Studies of Scythian Sites

From the 17th International Radiocarbon Conference held in Jerusalem, Israel, June 18-23, 2000.We propose a new method of cross-dating the wood samples based on the classical methods of spectral estimation. This method uses the average cross-spectral density as a function of the relative position of the series. Because it is not sensitive to phase shifts in data it is appropriate for cross-dating samples originating from geographically distinct areas. The accuracy of cross dating depends on the integrity of the samples used, and in the case of well-preserved wood samples, the precision of relative age comparison may reach a single year. The method was tested on two dendrochronological series from Scythian barrows of known age in Southern Siberia: the Pazyryk barrows (the Altai Mountains) and the Dogee-Baary -2 burials (Western Sayan Mountains) separated by 450 km. The analysis has shown that the Pazyryk barrow is younger by 80 +/4 yr than the Dogee-Baary -2 burials. This result is in agreement with the new chronology of Scythian-related sites suggested for Southern Siberia and Central Asia.The Radiocarbon archives are made available by Radiocarbon and the University of Arizona Libraries.

Endoscopic Detection of Gastric Metastases in Skin Melanoma

Aim. A clinical description of disseminated skin melanoma with endoscopic observation of its pathognomonic pigmented metastases into the stomach.Key points. A 66-yo patient was hospitalised with dyspnoea, general weakness, cough and suspected community-acquired pneumonia. The patient had a complex examination, including computed tomography, which revealed a presumed malignancy of the right lung with secondary changes in the chest and abdominal organs. Esophagogastroduodenoscopy (EGDS) visualised multiple pigmented spots and raised black plaques in cardia and the gastric body diagnosed as a metastasising melanoma in stomach. Endoscopic verification of the metastases confirmed the correct diagnosis of primary skin melanoma.Conclusion. Metastatic melanoma of the gastrointestinal tract has non-specific symptoms and most often occurs during the dissemination process. Endoscopy should be used to correctly verify pigmented mucosal lesions, necessarily allowing for non-pigmented gastric neoplasms in patients with skin melanoma in history
