INTRODUCTION The flora of a given region is an important indicator of ~:he state of its environment, as a result of the region's rlatural history as well as of the land changes caused by ~nan. The latter generally result in the expansion of taxa associated with man (emerophilous plants--Linkola, 1919; Jalas, 1955) and in the decline of negatively affected taxa (emerophobous plants), most of which become rare or extinct. Rare species are usually associated with sporadically occu...

Adhesion phenomena, even in a space environment, have been extensively investigated in the literature ([1][2]), but their role on the release of objects to freefloating conditions in space applications has not been thoroughly studied yet. The in-orbit precise release of a body implies the separation of its contacting surfaces from the engaging surfaces that belong to some kind of caging device. As this separation involves the rupture of the unavoidable adhesive forces, an impulse ...

Keywords: classification, computerized testing, sequential Bayes, sequential probability ratio test Many testing applications focus on classifying examinees into one of two categories (e.g., pass/fail) rather than on obtaining an accurate estimate of level of ability. Examples of such applications include licensure and certification, college selection, and placement into entry-level or developmental college courses. With the increased availability of computers for the administration ...

To understand the physics of faulting and rupture propagation for the great M8-class Nankai earthquakes that recur approximately every 100 years, a comprehensive drilling project is underway: the Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE; Tobin and Kinoshita, 2007), which is part of the Integrated Ocean Drilling Program (IODP). Stress levels along seismogenic faults must be eismogenic faults must be ismogenic faults must be known in order to understand processes control...

ntroduction As the world progresses, technological development has resulted in the availability of machinery, which translated into the development of a machine-based industry, resulting in increased emissions. The imposed travel restrictions worldwide in 2020 due to the COVID19 pandemic has resulted in a 6% reduction in energy demand compared to 2019 [1]. Despite the fact that the global energy-related CO2 emissions declined by 5.8% in 2020, they still remained at 31.5 Gt, which contribut...

People deal with diverse mathematical situations daily, all of which they have to learn to interpret so as to be able to comprehend and analyse the information they perceive (National Council of Teachers of Mathematics [NCTM] & National Association for the Education of Young Children [NAEYC], 2002). The world in which we live is a quantitative world, making it necessary to have adequate comprehension of mathematics to understand what happens around us. This is why Villarroel (2009) sta...

1. Introduction The ATLAS detector [1] is a general-purpose particle detector designed to study proton-proton interactions at the Large Hadron Collider (LHC) at CERN [2]. Its muon spectrometer is designed to trigger and identify muons produced in collisions and to measure their momenta [3]. Resistive Plate Chambers (RPC) [4] and Thin Gap Chambers (TGC) [5] are used as fast trigger chambers in the barrel (|휂| < 1.05) 1 and endcap (1.05 < |휂| < 2.4) regions, respectively. Three ...

Part 1: Arc and gas welding of steels and arc welding of nickel and nickel alloys 1 Scope This document specifies how a preliminary welding procedure specification is qualified by welding procedure tests. This document applies to production welding, repair welding and build-up welding. This document defines the conditions for the execution of welding procedure tests and the range of qualification for welding procedures for all practical welding operations within the qualification of th...

Levels of stress hormones and stable isotope ratios in animal tissues are increasingly recognized as important tools in studies on the physiology and ecology of wildlife (e.g. Kempster et al., 2007; Barger and Kitaysky, 2011; Deschner et al., 2012; Bryan et al., 2013). Keratinous tissues, such as hair and feathers, offer the longest record of an animal’s circulating glucocorticoid (GC) concentrations (Bortolotti et al., 2009; Macbeth et al., 2010; Jenni-Eiermann et al., 2015). Steroids...

Objectives: Perform a systematic review for the most relevant pelvic injury research involving PMHS. The review begins with an explanation of the pelvic anatomy and a general description of pelvic fracture patterns followed by the particular case of pelvic fractures sustained in pedestrian-vehicle collisions. Field data documenting the vehicle, crash, and human risk factors for pedestrian pelvic injuries are assessed. Method: A summary of full-scale PMHS tests and subsystem lateral pelvic te...
