Minimum Clearance Distance in Fall Arrest Systems with Energy Absorber Lanyards.

Accidents due to falls from height are one of the main causes of death in workplaces. Fall arrest systems (FAS) are designed to arrest the fall safely without injuring the accident victim. Their main mission is to restrain the body so as to prevent it from hitting the ground, generating forces and accelerations in the arrest process that are not harmful.

Vertical Archaeology: Safety in the Use of Ropes for Scientific Research of Pre-Columbian Andean Cultures.

Scientific research is sometimes subjected to go through field study in places that are difficult to access. Where man has not managed to reach through traditional techniques, work at height systems offer new possibilities, provide safety in exploration and represent an excellent tool that allows a new insight of spaces object of scientific research. For more than 20 years, the Ukhupacha team has been studying, analyzing and selecting the teams, techniques and rope progression systems that best adapt to archaeological works in vertical environments.

Average Force of Deployment and Maximum Arrest Force of Energy Absorbers Lanyards.

Energy-absorbing lanyards (EAL) are part of fall arrest systems (FAS), their main mission is to dissipate the energy generated during the fall, ensuring that the arresting force does not cause injury to the user. For the design of FAS as set out in the American standard Z359.6 and the Canadian Z259.

Optimization on Personal Fall Arrest Systems. Experimental Dynamic Studies on Lanyard Prototypes.

Tens of thousands of fall-from-height accidents take place at construction sites every year. These types of accidents range from minor to fatal, causing a significant financial burden to enterprises, personal and family traumatic experiences, high medical costs, as well as hard compensation claim settlements. It makes sense then, that some sort of effective personal protective equipment (PPE) be devised to stop these types of accidents from happening.

Molecularly Imprinted Polymers for the Selective Extraction of Bisphenol A and Progesterone from Aqueous Media.

This paper describes the development of a novel sorbent for selective extraction of endocrine disruptors (EDs) from aqueous media. The main goal was to obtain sufficient molecularly imprinted polymers (MIPs) for selective detection, preconcentration, and extraction of EDs such as bisphenol A (BPA) and progesterone (PG). Series of MIPs and their analogues, non-molecularly imprinted polymers (NIPs), were synthesised following a non-covalent imprinting strategy based on radical polymerisation.

Propellant's differentiation using FTIR-photoacoustic detection for forensic studies of improvised explosive devices.

The use of propellant for making improvised explosive devices (IED) is an incipient criminal practice. Propellant can be used as initiator in explosive mixtures along with other components such as coal, ammonium nitrate, sulfur, etc. The identification of the propellant's brand used in homemade explosives can provide additional forensic information of this evidence.

A Morphological and Morphometric Study of Bite Marks Caused by Mice (Mus Musculus) on Different Baits for Forensic Purposes.

In animal bites, the dental attributes can be fundamental in identifying the marks made by various species on different matrices. Although rodent bite marks have been studied in the context of postmortem interference, little research has used different baits to analyze these marks linking not only specific behavior patterns but also the possibility of structural damage. Twenty mice (Mus musculus) were exposed to different baits to study their bite marks in a controlled model.

The road to opportunities: landscape change promotes body-size divergence in a highly mobile species.

Landscape change provides a suitable framework for investigating population-level responses to novel ecological pressures. However, relatively little attention has been paid to examine the potential influence of landscape change on the geographic scale of population differentiation. Here, we tested for morphological differentiation of red-necked nightjars breeding in a managed property and a natural reserve situated less than 10 km apart.

Human-induced changes in landscape configuration influence individual movement routines: lessons from a versatile, highly mobile species.

Landscape conversion by humans may have detrimental effects on animal populations inhabiting managed ecosystems, but human-altered areas may also provide suitable environments for tolerant species. We investigated the spatial ecology of a highly mobile nocturnal avian species-the red-necked nightjar (Caprimulgus ruficollis)-in two contrastingly managed areas in Southwestern Spain to provide management recommendations for species having multiple habitat requirements. Based on habitat use by radiotagged nightjars, we created maps of functional heterogeneity in both areas so that the movements of breeding individuals could be modeled using least-cost path analyses.

The impact of education and acculturation on nonverbal neuropsychological test performance among Latino/a patients with epilepsy.

The present study examined the relationship between various sociocultural factors (e.g., acculturation, education), neurological variables (e.

Increasing culturally competent neuropsychological services for ethnic minority populations: a call to action.

US demographic and sociopolitical shifts have resulted in a rapidly growing need for culturally competent neuropsychological services. However, clinical neuropsychology as a field has not kept pace with the needs of ethnic minority clients. In this discussion we review: historical precedents and the limits of universalism in neuropsychology; ethical/professional guidelines pertinent to neuropsychological practice with ethnic minority clients; critical cultural considerations in neuropsychology; current disparities germane to practice; and challenges to the provision of services to racial/ethnic minority clients.
