Slips and falls and associated outdoor injuries are prevalent in cold climates. The objectives of this field investigation were to describe the consequences of slips and falls on ice and snow and the associated injuries, to assess the risks of various icy and snowy surfaces, to identify design needs of footwear, and to ascertain preventive measure preferences of outdoor workers. The organizations
Reaction of 2 equivalents of 1,3-bis-(di-tert-butylphosphinito)-2-methyl-propane (1a) with [Ir(COD)Cl](2) affords the first aliphatic diphosphinite PCP pincer complex with iridium, Ir(H){(t-Bu2POCH2)(2)C(Me)}Cl (2). The poor yield of 2 is partly explained by the formation of a di-nuclear byproduct [IrCl(COD)](2)(mu(2)-{(t-Bu2POCH2)(2)CH(Me)}) (3). Reaction of 1,3-bis-(di-iso-propylphosphinito)-2-m
Background: Supporting positive mental health development in adolescents is an important school health concern, but there is a need to investigate the suitability of the interventions used. Aim: To investigate the experiences of school health professionals in conducting a universal school-based program aimed at preventing depressive symptoms in adolescents. Methods: Twenty-two school health prof
Pinhole collimation is the most common method of high-resolution preclinical single photon emission computed tomography imaging. The collimators are usually constructed from dense materials with high atomic numbers, such as gold and platinum, which are expensive and not always flexible in the fabrication step. In this work, the authors have investigated the properties of a fusible alloy called Ros
Witnesses to a crime repeat and discuss the event several times during the legal process. The repetitions and discussions may influence the quality of recall as well as the confidence a witness feels in the remembered information. To probe this matter, participants in the current study viewed a short film and then either repeatedly, over a period of three weeks, 1) discussed the event in the lab 2
Thromboembolism during pregnancy is a rare complication with a potential fatal outcome. Very little is known about long-term effects and therefore 104 women with thrombosis during pregnancy or puerperium were identified and their subjective complaints were assessed in a questionnaire. All had their thrombosis diagnosed by objective methods and the median follow-up time was 11 years. In spite of an
We studied the mechanism of CO oxidation on O-precovered Pd(111) surfaces by means of fast x-ray photoelectron spectroscopy (XPS). The oxygen overlayer is compressed upon CO coadsorption from a p(2x2) structure into a (root 3x root 3)R30 degrees structure and then into a p(2x1) structure with increasing CO coverage. These three O phases exhibit distinctly different reactivities. (1) The p(2x2) pha
Denitrification is a critical process that can alleviate the effects of excessive nitrogen availability in aquatic ecosystems subject to eutrophication. An important part of denitrification occurs in benthic systems where bioturbation by meiofauna (invertebrates <1mm) and its effect on element cycling are still not well understood. Here we study the quantitative impact of meiofauna populations of
This article develops two arguments. First, at a national level in Bulgaria, the human trafficking framework is inoperable for identifying abuses worthy of consideration. By comparing the Bulgarian criminal law definition of human trafficking with the international law definition, I argue that the national criminal law definition is overly inclusive. This state of the Bulgarian criminal law makes
Developmental plasticity is increasingly recognized as important for ecological and evolutionary processes. However, few studies consider the potential for delayed effects of early environments. Here, we show that tadpoles hatching from clutches exposed to water mold (Saprolegnia) have 20% decreased mass at metamorphosis, despite no further exposure subsequent to hatching. The effects were consist
This paper formulates a bio-economic model to analyze community incentives for wildlife management under benefit-sharing programs like the Communal Areas Management Programme for Indigenous Resources (CAMPFIRE) in Zimbabwe. Three agents influence the wildlife stock: a parks agency determines hunting quotas, outside poachers hunt illegally, and a local community may choose to protect wildlife by di
The present study focuses on in situ as well as ex situ studies on the sintering of pre-compacted powder mixtures of 50 at% Nickel-50 at %Titanium. In situ studies were carried out by monitoring the changes in morphology of the fracture surface of the compact continuously during heating in the hot stage of an environmental scanning electron microscope. Results on the initiation of sintering and it
There is a large financial incentive to minimise operations and maintenance (O&M) costs for offshore wind power by optimising the maintenance plan. The integration of condition monitoring (CM) and structural health monitoring (SHM) may help realise this. There is limited work on the integration of both CM and SHM for offshore wind power or the use of imperfectly operating monitoring equipment.
The student of innovation studies is faced with a vast, multi-national and interdisciplinary field on which she must gain an overview and make a novel contribution. There exist a plethora of academic journals, networks, conferences and fora wherein researchers of innovation discuss and advance the topic. How to manage and understand this is a major challenge. This paper helps to make sense of this
Early detection of risk of breast cancer is of upmost importance for effective treatment. In the field of medical image analysis, automatic methods have been developed to discover features of ductal trees that are correlated with radiological findings regarding breast cancer. In this study, a data mining approach is proposed that captures a new set of geometrical properties of ductal trees. The ex
