Under certain circumstances, the collision of magnetic monopoles, topologically locked-in regions of false vacuum, leads to topological inflation and the creation of baby universes. The future evolution of initial data represented by the two incoming monopoles may contain a timelike singularity but this need not be the case. We discuss the global structure of the spacetime associated with monop...

The aim of this work was to study the effect of spray drying conditions on quality of coconut sugar powder and their characteristics. Effects of inlet air temperature (120°C, 150°C and 180°C) and maltodextrin concentrations (DE 9-12) at 10%, 20% and 30% (w/v) on physical properties of spray dried coconut sugar powder were investigated. Buchi mini spray dryer, model B-290, was used in this work....

A co-ordinated empirical European work (Project REPRESENTATION, MM 1045) has been led in six countries, with the aim of getting an insight of pupils’representations regarding ICT. A common protocol was defined. According to it, the pupils of one classroom in each country (fourth and fifth graders) were asked to draw a computer, to label its parts and to write short texts about computer uses. Re...

The poor quality of wireless electrocardiography (ECG) recordings can lead to misdiagnosis and waste of medical resources. This study presents an interpretation of Lempel-Ziv (LZ) complexity in terms of ECG quality assessment, and verifies its performance on real ECG signals. Firstly, LZ complexities for typical signals, namely high-frequency (HF) noise, low-frequency (LF) noise, power-line (PL...

30 novel compounds have been synthesized from 25-hydroxyprotopanaxadiol (25-OH-PPD) and their in vitro anti-tumor activities were tested on three cancer cell lines and one normal cell line (IOSE144) by standard MTT assay. The results showed that compound 27 exhibited the best anti-tumor activity in the in vitro assays. Compounds 1, 2, 16, 17, 18, 27, 28 and 29 have better anti-tumor activities ...
