Cellulose nanofibers (CNFs) from banana peels was evaluated as promising stabilizer for oil-in-water emulsions. CNFs were treated using ultrasound and high-pressure homogenizer. Changes on the size, crystallinity index and zeta potential of CNFs were associated with the intense effects of cavitation phenomenon and shear forces promoted by mechanical treatments.

The aim of this study is to compare and evaluate the dose distribution and physical characteristics of two algorithms Anisotropic Analytical Algorithm (AAA) and Acuros XB (AXB) in Eclipse v13.6 software in regions heterogeneous densities. Computed Tomography Simulation (CT – Sim) data of 48 treated cancer patients (20 head and neck cancer (H&N) patients, 15 esophageal cancer patients, 8 lung cancer patients with 3 Dimensions Conformal Radiation Therapy (3D-CRT) and 5 lung cancer patients treated with Volumetric Modulated Arc Therapy (VMAT)) were used to replan the Eclipse v13.

Kenen (1969) hypothesizes that countries that are largely dependent on one export commodity could experience weaker monetary integration and synchronize the business cycle among them. This paper aims to retest Kenen’s hypothesis, which is applied to the seven largest oil-producing countries in the Islamic world. This study employs the optimum currency area index and the Pearson correlation matrix to determine the degree of integration and synchronization of the business cycle. This study empirically proves that most oil-producing countries are tightly integrated.

The object-oriented image analysis delineates segments of homogeneous image areas. The delineated segments are classified to real world objects based on spectral, textural, neighbourhood an object specific shape parameter. Object-oriented classification of highresolution imagery is a challenging job for the remote sensing community. Identification of the object-oriented classes based on objects leads to better classification. In this project, the object-oriented classification for tomato in Shoolagiri and surrounding villages of Krishnagiri district in Tamil Nadu, India.

Two families of certain nonsymmetric generalized Jacobi polynomials with negative integer indexes are employed for solving third- and fifth-order two point boundary value problems governed by homogeneous and nonhomogeneous boundary conditions using a dual Petrov–Galerkin method. The idea behind our method is to use trial functions satisfying the underlying boundary conditions of the differential equations and the test functions satisfying the dual boundary conditions.

SOLVABILITY CONDITIONS FOR SOME DIFFERENCE OPERATORS N. C. APREUTESEI AND V. A. VOLPERT Received 24 June 2004 Infinite-dimensional difference operators are studied. Under the assumption that the coefficients of the operator have limits at infinity, limiting operators and associated polynomials are introduced. Under some specific conditions on the polynomials, the operator is Fredholm and has the zero index. Solvability conditions are obtained and the exponential behavior of solutions of the homogeneous equation at infinity is proved. 1.
