New Dilemma Zone Mitigation Strategies
… lead to a red light running and a right-angle Collison when passing through the intersection or a rear-end collision when failing to stop safely.Improperly timed traffic signal intervals result in the inability of the drivers to make the right decision and can place them in the dilemma zone. …

Laser-Emissionsspektrometrie für die Partikelanalyse von Prozessgasen bei der Roheisenerzeugung
… pressure as well as the electron density due to collison and relaxation processes. Plasma properties are changed which lead to a decrease of line intensity, line broadening and to a decrease of signal-to-backround ratio. Consequently the gas pressure has an impact on the plasma dynamics and must …

New virulence mechanisms in Yersinia pestis, the plague (Black Death)-causing bacterium: A re-emerging and bioterror pathogen
… various doses of Y. pestis CO92 aerosolized by a Collison nebulizer and determined the LD50 dose, bacterial dissemination, cytokine/chemokine production, and tissue damage over a 72-h course of infection. Plague in mice and rats mimics disease in humans and understanding disease progression in …

Getting out of the water and into the air: Understanding aerosolization of the bacterium Pseudomonas syringae from aquatic environments
… of phylogenetic subgroups present in the lake. A Collison nebulizer was used to aerosolize an Ice+ and an Ice- strain of P. syringae under artificial laboratory conditions. The aerosolization of P. syringae was not influenced by water temperature between 5° and 30°C. In general, the culturability …

Nighttime evapotranspiration in a semiarid climate using a hemispherical chamber
Nighttime evapotranspiration (ETn) is typically underestimated, miscalculated or ignored when producing daily, seasonal, or annual evapotranspiration (ET) models using energy-balance and aerodynamic conceptual models, such as the Penman-Monteith ET equation. The objective of this study is to …

A Systems-Based Approach to Examine the Molecular Basis of Interactions between Human Monocytes and Human Micro-Vascular Endothelium
Human monocytes comprise three distinct subsets, defined by their relative expression of CD14 and CD16. These subsets appear to have different functional roles, which are only recently becoming delineated. Functional differences include the manner in which different monocytes interact with blood …

The development and origin of muscle fatigue after hexagonal-barbell deadlift exercise of different loads and velocities: contributing to a knowledge-base for coaches to make evidence-informed decisions regarding athletic training programmes
Athletes perform bouts of resistance exercise to develop athletic performance and reduce the risk of injury. Fatigue in response to exercise can be associated with alterations to voluntary muscle activation or contractile function. Recent literature has proposed terms of performance fatigability …

Chemoprevention of Lung Carcinogenesis: Aerosol Administration and Deposition in the Mouse Lung
… compounds were aerosolized with a custom-built Collison atomizer. The resultant drug aerosols were delivered to the mice that were retained in a nose-only exposure chamber. Four small molecular inhibitors: gefitinib, erlotinib, lapatinib and wortmannin), and four natural agents: resveratrol, …

On the Pebbling Numbers of Graphs
Graph pebbling is an application which has evolved from the study of graph theory. The goal of pebbling in a graph is to use pebbling steps to move one pebble onto a designated root vertex. A pebbling step is produced by taking two pebbles from a vertex, moving one of them to an adjacent vertex, …

Relay Succession in the Senior Pastorate: A Multiple Case Study Method
The purpose of this research was to articulate the process and principles of relay succession in the senior pastorate within the Church of God (COG). The research was accomplished through three phases and four case studies. The first phase--define and design--sought to review the precedent …

The South African military aerospace industry: An overview of the special defence account more commmonly known as 'The South African Arms Deal'
The paper focuses specifically on the South African Military Aerospace Industry as most of the weapons procured under the arms deal were military aircraft. Taking into account the numerous social needs of South Africa, the purpose of this paper is to inter alia try to establish the rationale behind …

Interactions of Organic Fluorophores with Plasmonic Surface Lattice Resonances
<p>It is common knowledge that metals, alloys and pure elements alike, are lustrous and reflective, the more so when a metal surface is flat, polished, and free from oxidation and surface fouling. However, some metals reflect visible light, in the 380 nm to 740 nm range of wavelengths, much more …

Seasonal use and mortalities of mammals along the Phalaborwa – Hoedspruit railway line in Balule Nature Reserve, South Africa.
Railways are essential transportation corridors that facilitate the movement of goods and people with important environmental and economic benefits. Despite these benefits, railways and trains can negatively affect wildlife through mortalities, barrier effects, disturbances, and habitat loss. There …
