On Superconnections and the Tachyon Effective Action
We propose a form of the effective action of the tachyon and gauge fields for brane-antibrane systems and non-BPS Dp-branes, written in terms of the supercurvature. Kink and vortex solutions with constant infinite gauge field strength reproduce the exact tensions of the lower-dimensional D-branes. We discuss the relation to BSFT and other models in the literature
βHuman Babesiosisβ: An Emerging Transfusion Dilemma
Babesiosis, a common disease of animals, can infect humans via vector βtick biteβ, particularly in endemic areas. The recent reports of fatal cases in Hepatitis C and postliver transplant patients resulting from transfusion of contaminated blood should alert the medical profession regarding this emerging dilemma in endemic as well as nonendemic areas and the need for accurate blood screening for transfusion. Here, we illustrate different stages of the parasite lifecycle, progression of babesiosis in animal model, some aspects of pathologic outcomes, ongoing therapeutic modalities, and a feasible Acridine Orange fluorescent methodology for the diagnostic evaluation of blood samples
A research on determining the friction losses formed in the small diameter floppy polythene pipe lines
In pressured irrigation systems, water flowing in pipes is stable from the point of view of the hydraulic and it gradually decrease through the pipe lines. In sprinkler irrigation systems, sprinkler head pressure through the pipe line is different due to friction and local losses formed in parts of the pipes between sequent sprinkler heads and the differences resulting from slope. Generally, sprinkler head pressure has a maximum level in the beginning of lateral pipe lines and a minimum level in the end of lateral pipe lines. The velocity of water flow in the pipe line, the diameter and length of the pipe and the friction loses formed as a result of roughness inside the pipe should be known for a good design. The easiest andfastest way is to make use of the values given in the tables or diagrams determined by the equation of Hazen-Williams. However, no data related to floppy polythene (PE) pipes with small diameter is available in the tables and diagrams mentioned. In this study, values relating to friction losses and pressures formed in 10, 20, 30,…, 100 m through the pipe for the without slope in different velocity (0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 m s-1) and water flow have been measured and it was found that connection between them using floppy PE pipes (6 bar) with small diameter (Ø20, 25, 32, 40 and 50) have been produced by some plastic companies in Turkey and particularly used in the irrigation systems in landscape areas. Inconclusion, it was stated by the people who worked on the experiment that the parameters obtained could be used
Breast cancer with diabetes insipidus
Diabetes insipidus (DI) is a rare clinical condition, which is usually caused by neurohypophyseal or pituitary stalk infiltration in cancer patients. Case report: we present a 62-year old metastatic breast cancer woman with DI. She admitted to the hospital because of nausea, vomiting, polyuria and polydipsia, while she was on no cytotoxic medication. She had no electrolyte imbalance except mild hypernatremia. The CT scan of the brain yielded a suspicious area in pituitary gland. A pituitary stalk metastasis was found on magnetic resonance imaging (MRI) of pituitary. Water deprivation test was compatible with DI. A clinical response to nasal vasopressin was achieved. Conclusions: Cancer patients who have symptoms such as nausea, vomiting, polyuria and polydipsia while they are not on chemotherapy should be evaluated for not only metabolic complications like hypercalcemia but also posterior pituitary or stalk metastasis MRI could be the choice of imaging for pituitary metastasis.ΠΠ΅ΡΠ°Ρ
