Colombeau Solutions Of A Nonlinear Stochastic Predator--Prey Equation, Uluğ Çapar Jan 2013

Colombeau Solutions Of A Nonlinear Stochastic Predator--Prey Equation, Uluğ Çapar

Turkish Journal of Mathematics

The solution of a random semilinear hyperbolic system with singular initial data is sought as a random Colombeau distribution. The product of 2 additive white noises is well tackled within the theory of random Colombeau distributions. In the special case of a random predator--prey system, the exact Colombeau solution is obtained under some assumptions when the process is driven by doubly reflected Brownian motions.

Spatial Pattern Analysis Of Peganum Harmala On The Salted Lower Chelif Plain, Algeria, Adda Ababou, Mohammed Chouieb, Abdelkader Bouthiba, Djamel Saidi, Mahfoud M'Hamedi Bouzina, Khalladi Mederbal

Turkish Journal of Botany

Peganum harmala L. (Zygophyllaceae), native to arid and semiarid rangeland, has been widely studied biochemically, pharmaceutically, and medicinally, but is largely unknown ecologically. In the lower Chelif, Algeria, this plant is largely present and shows a clear clumped pattern, which indicates the strong effects of environmental conditions. Our redundancy analysis showed that the geographic distribution of this species was positively correlated with sand and pH and negatively correlated with conductivity, Na^+, and clay. The Gaussian model suggested that 9.4 mmhos/cm conductivity and sand contents greater than 40% are optimum for this plant. The spatial distribution map obtained through the kriging …

The King's Toilet: Cruising Literary History In Reinaldo Arenas' Before Night Falls, LáZaro Lima

Latin American, Latino and Iberian Studies Faculty Publications

In this article I will read Before Night Falls as Arenas' queer version of Cuban literary history and his relation to it. Against the commonplace assertions that demand that Before Night Falls be primarily understood, if not exclusively, as an invective against Fidel Castro or, in the other extreme, as an ars moriendi and AIDS testimonial from a sexual dissident, I wish to revisit this text on the twentieth anniversary of its publication to underscore a missed reading that can help situate how Arenas, one of the most transgressive writers theorized in this collection as the Generation of '72, might …

Turkish Journal of Medical Sciences

To investigate the role of cell adhesion molecules CD44v6 and CEA in the occurrence, development, and metastasis of colorectal cancer (CRC). Materials and methods: The expression of CD44v6 and CEA in 76 CRC tissues and 43 normal colon tissues was detected using an immunohistological technique. The relationship between the 2 molecules’ expression and their pathologic characteristics, especially for metastasis, was investigated. Furthermore, the relevance between the expression of CD44v6 and of CEA was also assessed. Results: Expression of CD44v6 and CEA protein in CRC tissues was higher than in paracarcinoma tissue and normal colorectal mucosa (both P < 0.001). Positive expression of CD44v6 in CRC was associated with lymph node metastasis, Dukes’ stage, and histological differentiation. Higher expression intensity of CEA in CRC was related to lymph node involvement, distant metastasis, and invasion depth. Combining analysis of CD44v6 and CEA can improve the sensitivity and specificity in evaluating the metastatic potential of CRC (P < 0.05). There was no relevance between the expression of CD44v6 and CEA in CRC (P > 0.05). Conclusion: CD44v6 …
