In this work, we describe the synthesis of a novel 9-aminoacridine derivative that presents surprisingly different colors when exposed to neutral, acidic or basic mediums with potential application as pH indicator in organic solvents. Furthermore, pKa and molar absorptivity values were determined and theoretical studies supported by density functional theory (DFT) calculations were performed to...

Introduction The process of integrating technology into mental health pathways represents a social transformation that we are gradually getting used to. But does it represent valid alternative to face-to-face care processes? In this paper will consider telesychology as tool for treating anxiety and depression its validity. Anxiety harmful individuals, suffering from these disorders, their careg...

Operating System (OS) selection plays a vital role in determining the usability of a computer or microcomputer. This application note will discuss the differences between the different flavors of the Linux OS’s and the different mediums of installing the software. There will be comparisons of differences between the software, as well as which operating system will best suit the user’s needs.

A simple, sensitive gold nanoparticle (GNP)-based dot-blot immunoassay has been developed for detecting Alzheimer's disease related β-amyloid peptide 1-42 (Aβ(1-42)) down to a 50 pg mL(-1) level in aqueous solution. Practical samples (cerebrospinal fluid (CSF), cell culturing mediums and cell lysates) have been used to demonstrate the ability of the assay.

In this work, CuO films were produced by the successive ionic layer adsorption and reaction (SILAR) method. The oxidation process was applied to in three different mediums as air, oxygen argon. kept at 400 °C for 2 hours each medium during process. effect of selected on physical properties investigated. This study showed that can vary significantly mediums. XRD studies reveal all are polycrysta...

Commercial food packages may contain multiple messages. Packaging designers try to integrate all messages into a coherent design. Designers use text, images or stylistic features, but these mediums differ in their suitability communicate specific product benefits. To evaluate the usefulness and effectiveness of three mediums, we not only obtained consumer evaluations packaging designs, also mon...

Background: In vitro model studies are becoming increasingly popular for experimental research designs. They include isolation and expansion of cells of a particular tissue, such as the nervous tissue which contributes to understanding the underlying mechanisms in many pathologies. It enables  the scrutinization of intracellular signaling pathways responsible for cell death. OBJECTIVES: In the ...
