1.1. Random walk in random potential. Let S = (S(n))n∈N0 be a nearestneighbor random walk on the lattice Zd, with start at the origin and drift h into the direction of the first axis. We suppose S being defined on a probability space (Ω,F , Ph), and we denote by Eh the associated expectation. Such a random process is characterized by the distributions of its finite-step sub-paths S[n] def = S(0...

A bacterial strain was isolated from dhal industry red gram waste and identified as Bacillus. A thermostable extracellular amylase was partially purified from the strain. Optimum temperature and pH for the enzyme were found to be 60°C and 6.5, respectively. The maximum amylase production was achieved with maltose as carbon source. Among the nitrogen sources, peptone and yeast extract produced m...

The courses of the Doctoral Program provide Ph.D students in Materials Engineering with a common, basic knowledge on Materials Science and Technology, followed by a specialized training in specific fields. The objective is to combine the theoretical knowledge with the skills required by technology in order to form qualified researchers who can manage the design, manufacturing and use of traditi...

This study aimed to determine physicochemical parameters for obtaining prediction equation in order to evaluate the postharvest quality of tomatoes (Solanum lycopersicum L.). A imaging system was used to measure L*a*b* color space. In tomatoes (variety Caiman) were evaluated weight loss, oBrix, pH, titrable acidity, firmness and oHue over 17 days of storage. The experimental results demonstrate...

Using ideas from an article of P. Bieliavsky, M. Rooman and Ph. Spindel on BTZ black holes, I construct a family of interesting examples of quasi-Poisson actions as defined by A. Alekseev and Y. Kosmann-Schwarzbach. As an application, I obtain a genuine Poisson structure on SL(2, R) which induces a Poisson structure on a BTZ black hole.

With increasing use of arterial blood gas analysis in various ward and other hospital settings to aid medical diagnosis and management, nurses who can interpret results are often able to initiate earlier interventions and understand the reasons for medical interventions. This article enables nurses to interpret such results.

A pH-sensitive RuO₂ electrode coated in a commercial cyanoacrylate adhesive typically exhibits very low pH sensitivity, and could be paired with a RuO₂ working electrode as a differential type pH sensor. However, such sensors display poor performance in real sample matrices. A pH sensor employing a RuO₂ pH-sensitive working electrode and a SiO₂-PVB junction-modified RuO&...
