In this paper fatigue crack initiation and propagation in notched plate under constant amplitude loading through tensile residual stress field of 2024 T351 Al-alloy plate were investigated. Residual stress field was generated by plastic deformation using finite element method (FEM) where isotropic hardening in Von Mis…
Aim: The objective of the present investigation was to study the effect of PVP on in vitro dissolution of aceclofenac from coprecipitates.Materials and Methods: Aceclofenac coprecipitates (CP) with different drug loadings were prepared and in vitro dissolution studies of pure drug, physical mixtures and coprecipitates…

In the Experimental Section of the original article,1 there is an error in the synthetic protocol for 2-ethynylchrysene (9). The hydrolysis reaction was carried out at room temperature (not at 80 °C). The corrected synthetic protocol is given below. The authors apologize for this error. 2-Ethynylchrysene (9): 2-Bromoc…
A wound that will accept a skin graft must be free of infection, free of devitalized tissue, and must have an adequate blood supply. Skin grafts are classified as either split thickness or full thickness and are selected depending on the size of the defect to be covered and the thickness of coverage that is desired fo…
The term self-assembly describes processes where a system of disordered pre-existing components forms a more organized structure or pattern as the result of specific, local interactions among the components themselves, without external direction. When the constitutive components are molecules, the process is called mol…
In recent years the concept of molecular self-assembly has become a driving force for the development of new biomaterials. Molecular self-assembly is one of the twomain approaches to the production of well-defined, functional nanostructures essential for the fast grow- ing field of nanotechnology; in particular molecula…
This chapter provides an overview of the strategies that may be used to produce molecular materials based on peptides and their derivatives. Peptides are highly versatile building blocks for the production of functional molecular materials, as is evident from the myriad of functional nanoscale structures encountered i…
Manipulation of self-assembled peptide nanostructures is a critical issue through the process of characterization and integration of these biological structures in different applications, e.g. devel- opment of biosensors, electronics, drug-delivery systems, surface functionalization, among others. Using the right manip…
The temperature-dependent property of band gap in colloidal PbSe quantum dots has been investigated from both experiment and theory above room temperature. When the particle size increases, the temperature coefficient evolves from negative values to zero and then to positive value following the trend to its bulk mater…
In 2007, the European Commission (EC) commissioned a group of experts to undertake the revision of Report Radiation Protection (RP) 91, written in 1997, on 'Criteria for acceptability of radiological (including radiotherapy) and nuclear medicine installations'. The revised draft report was submitted to the EC. Before…
The EC (European Commission) Directive on radiation protection of patients requires that Criteria for Acceptability of Equipment in Diagnostic Radiology, Nuclear Medicine and Radiotherapy be established throughout the member states. This paper reviews the background to this requirement and to its implementation in pra…
Gold (Au) and silver (Ag) are the most commonly used materials in nanoSPR since they exhibit strong SPRs in the visible-near-infrared (NIR) wavelength range [32]. At these wavelengths, the dielectric properties of the metals are described by a complex, wavelength-dependent dielectric coefficient, e e(l) = er(l) + iei(…
Proteins are perhaps one of themost diverse and complex structures in nature. The functional diversity of proteins is very broad. Enzymes perform catalytic functions, converting substrates into products with an incredible speed and specificity compared with common organic reactions. There are structural proteins in the…
Nozzle is the main part of various spinning systems such as air-jet and Murata air vortex systems. Recently, many researchers worked on the usage of the nozzle on different spinning systems such as conventional ring and compact spinning systems. In these applications, primary purpose is to improve the yarn quality. In…

To achieve both low line resistance and high electromigration (EM) reliability, CuSiN was formed on CuxO, which was purposely left on the Cu interconnect. Oxide on the Cu surface effectively suppressed Si diffusion into the Cu line: this diffusion had, in the absence of the oxide, appeared during CuSiN formation and i…
Attractive interactions between adjacent spheroids and excluded volume effects favor their parallel alignment. Parallel spheroids can be arranged into a variety of densely packed two-dimensional and three-dimensional lattice configurations. All of these configurations turn out to have the same lattice energy. A simila…
The first-principles electronic band structure calculation has been used to examine the relationship between the Bi/Sb composition ratio and the Seebeck coefficient in (Bi1-x Sb x )2Te3. The Te/Se ratio dependence in Bi2(Te1-x Se x )3 has also been investigated and the results have been compared. Because spin–orbit in…
AIM: This study assessed the phycoperiphyton biomass in two regions submitted to different human impacts on Juara Lake, a coastal ecosystem with multiple uses, to order to test the hypothesis that the sampling sites that receive domestic sewage shows higher biomass values. METHODS: It was installed three experimental…
