A new species of Tmesiphantes Simon, 1892, is described from sandstone/quartizitic caves of Chapada Diamantina, Bahia State, Brazil. This is the fifth species of the genus and the first record of a troglobitic mygalomorph in Brazil. A key is presented for all Tmesiphantes species.

Background & Aims of the Study: In this study, we evaluate the respiratory deaths which were caused by exposure to PM10 in Ahwaz, Bushehr and Kermanshah cities of Iran during 2015 by Air model Q2.2.3. Materials and Methods: The required data gathered from the dep...

The external-detector method of fission-track (FT) dat­ ing is capable of providing FT ages for individual mineral grains. As a result, tliis method when applied to dating detrital zircons in unreset sandstone samples has much potential for resolving the depositional age and provenance of the samples. One problem is that individual FT grain ages for detrital zircons usually have fairly low prec...

Sandstone intrusions have always caught the attention of geologists and are in many cases highly spectacular due to the contrast between light-coloured intrusive sandstones and dark host mudstones. In recent years it has become increasingly clear, that large, irregular bodies of massive sandstone may also be of intrusive origin, but the timing and nature of remobilization of the primary deposit...

We analyze statistical scaling of structural attributes of two millimeter scale rock samples, Estaillades limestone and Bentheimer sandstone. The two samples have different connected porosities and pore structures. The pore-space geometry of each sample is reconstructed via X-ray micro-tomography at micrometer resolution. Directional distributions of porosity and specific surface area (SSA), wh...

Early regeneration success of upland oaks (Quercus spp. L.) was compared for three regeneration cutting treatments in the Sandstone Mountain Region of northern Alabama. Two 4-acre replications each of block dearcutting. strip cutting, and deferment cutting were established on north-facing slopes. The three harvesting treatments were applied in midsummer. Regeneration subplots were reinventoried...

Deposits of the Warchha Sandstone in the Salt Range, Pakistan are characterised by a range of fluvial facies and architectural elements that together preserve a record of both the proximal and distal parts of a meandering river system that drained the northern margin of Gondwanaland. Several fining-upward cycles are recognised and completely preserved cycles can be divided in to three parts; a ...

We aimed to find the prevalence and some factors relating with unwanted pregnancy. Methods. It was a cross-sectional study on 400 randomly pregnant women, who were referring to different health centers in Ahwaz city during 2010. Data was conducted based on questionnaire, and all the analysis was performed using SPSS (version 17) statistical analysis software. Results. The prevalence of unwanted...
