In this study soil properties and root biomass responses to prescribed fire were investigated in 25-30 year-old calabrian pine (Pinus brutia Ten.) stands in Edirne, Turkey. The stands were established by planting and were subjected to prescribed burning in July 2005. Soil respiration rates were determined every two months using the soda-lime method over a two-year period. Fine (> or = 2 mm diam...

We use techniques from applied matrix analysis to study small world cutoff in a Markov chain. Our model consists of a periodic random walk plus uniform jumps. This has a direct interpretation as a teleporting random walk, of the type used by search engines to locate web pages, on a simple ring network. More loosely, the model may be regarded as an analogue of the original small world network of...

OBJECTIVES Discrete choice experiments (DCEs) are routinely used to elicit patient preferences to improve health outcomes and healthcare services. While many fractional factorial designs can be created, some are more statistically optimal than others. The objective of this simulation study was to investigate how varying the number of (1) attributes, (2) levels within attributes, (3) alternative...

The mineral kovdorskite Mg2PO4(OH)·3H2O was studied by electron microscopy, thermal analysis and vibrational spectroscopy. A comparison of the vibrational spectroscopy of kovdorskite is made with other magnesium bearing phosphate minerals and compounds. Electron probe analysis proves the mineral is very pure. The Raman spectrum is characterized by a band at 965 cm(-1) attributed to the PO4(3-) ...

In information retrieval community a lot of work is focused on increasing efficiency by capturing statistical features. The other dominant approach is to improve the relevance by capturing the semantic and contextual information which is invariably inefficient. Generally the two approaches are assumed to be diametrically opposite. In this paper we have tried to combine the two approaches by pro...

Pollution from consumption and production is an inevitable part of economic processes. We employ a materials balance approach and develop an endogenous growth theory, with recycling activity, to examine the evolution of the economic and environment systems. This paper provides feasibility and optimality conditions for sustainable economic growth with rising environmental quality. The fundamenta...

A 3204-bp full-length cDNA of bovine NALP9 was cloned and its genomic organization was analyzed. The 2988-bp open reading frame covers 9 exons and encodes a deduced protein of 996 amino acids containing Pyrin, Nacht and leucine-rich repeat domains like the human NALP gene family members. Mapping with the WGRH5000 panel and fluorescence in situ hybridization assigned NALP9 in close vicinity to B...

BACKGROUND In recent years, it has been increasingly recognized that the absence of mental disorder is not the same as the presence of positive mental health (PMH). With the PMH-scale we propose a short, unidimensional scale for the assessment of positive mental health. The scale consists of 9 Likert-type items. METHODS The psychometric properties of the PMH-scale were tested in a series of s...
