We present new spectroscopic metal abundances for 74 RR Lyrae stars in ω Cen obtained with FLAMES. The well-known metallicity spread is visible among the RR Lyrae variables. The metal-intermediate (MInt) RR Lyrae stars ([Fe/H] ∼ −1.2) are fainter than the bulk of the dominant metal-poor population ([Fe/H] ∼ −1.7), in good agreement with the corresponding zero-age horizontal branch models with c...

A web-based tool-set called TIO was created for mobile learning with emphasis on study courses in mathematics, informatics, natural sciences and technology (MINT). Mobile learning is a variant of E-learning which is based on mobile user devices with Internet access. It was tested for numerous software and hardware configurations users may have and proved to be technically working. TIO consists ...

Salvia divinorum Epling & Jativa is an hallucinogenic mint traditionally used for curing and divination by the Mazatec Indians of Oaxaca, Mexico. Young people from Mexican cities were reported to smoke dried leaves of S. divinorum as a marijuana substitute. Recently, two S. divinorum specimens were seized in a large-scale illicit in-door and out-door hemp plantation. Salvinorin A also called di...

These data are presented in support of a plastid phylogenomic analysis of the recent radiation of the Hawaiian endemic mints (Lamiaceae), and their close relatives in the genus Stachys, "The quest to resolve recent radiations: Plastid phylogenomics of extinct and endangered Hawaiian endemic mints (Lamiaceae)" [1]. Here we describe the chloroplast genome sequences for 12 mint taxa. Data presente...

The aim of this contribution is to examine the effect of an indiscriminate epidemic on a population to assess whether or not a catastrophic event can be identified from examination of paleodemographic data. Using paleodemographic techniques, the death assemblage from the Royal Mint site, London, a Black Death cemetery dated 1349 AD, is compared with that from St. Helen-on-the-Walls, York, which...

Indoor localization systems that are accurate and robust with respect to propagation channel conditions are still a technical challenge today. In particular, for systems based on range measurements from radio signals, non-line-of-sight (NLOS) situations can result in large position errors. In this paper, we address these issues using measurements in a representative indoor environment. Results ...

Six green leafy vegetables and herbs - spinach, amaranth, bengal gram, cauliflower, mint, coriander and carrots - were analyzed for moisture, protein, ascorbic acid, beta-carotene, total iron, ionizable iron (as % of total iron) in vitro iron (% of total iron), copper, manganese and zinc. Moisture content of the leaves and carrots varied from 75.1 percent (bengal gram) to 95.4 percent (carrot) ...

In this Thesis, I designed and implemented a programming language and compiler for use under the COntext INterchange Architecture, MINT. The language, known as PENNY, was born from COINL, a deductive object-oriented language originally used to program under the MINT architecture. This new language boasts a new look and feel to provide a greater abstraction and minimize the complexity for the us...

The performance of acoustic multichannel equalization techniques, which are based on estimating and inverting the room impulse responses (RIRs) between the source and the microphone array, is known to be very sensitive to estimation errors of the RIRs. In order to increase the robustness, it has been proposed to use regularization with the aim of decreasing the energy of the inverse filters. Th...
