Accuracy, Reliability, and Safety of Luminol in Bloodstain Investigation

2002

ABSTRACTThe reliability of luminol as a presumptive test reagent was studied in this work. The possibility of obtaining a false negative subsequent to contamination of the test specimen was determined. The behavior of luminol with respect to a contaminant was compared to other reagents used in similar tests. Following an analysis of the test results, other test sensitivity, and safety data, it was concluded that luminol is a more reliable reagent than others due to a higher improbability of producing false positives and false negatives, apart from being safer than other substances. It should, therefore, be considered as a “preferable” or “first choice” reagent for use in presumptive tests.

Intoxikationen mit Medikamenten im Kindesalter bei einem regionalen Giftinformationszentrum

2006

BACKGROUND: Drug poisonings in childhood account with about one fourth for the most important group of poisonings in this age group. METHOD: From 1995 to 2004 the inquiries to a poison centre regarding drug poisonings of children

Effets, sur les potentiels évoqués auditifs précoces, d'un bruit de trafic routier, d'une benzodiazépine et de leur conjugaison

1997

Resume Au total, 30 hommes et 30 femmes jeunes (autant d'anxieux que de non anxieux dans chaque groupe) ont ete exposes dans un ordre tire au sort: i) a un bruit de trafic routier emis pendant 15 min a un niveau sonore de 75 dBA; ii) a ce meme bruit pendant 15 min 1 h apres avoir ingere 0,25 mg d'alprazolam (Xanax * ); iii) a uniquement 0,25 mg d'alprazolam. Les potentiels evoques auditifs precoces (PEAp) ont ete recueillis avant et apres exposition au bruit (pour la passation sans bruit on a observe les. memes. horaires, de mesure). L'alprazolam a agi sur la cochlee et peut etre considere comme un facteur d'adaptation au bruit sur les voies auditives explorees par les PEAp.

Is naturalistic driving research possible with highly instrumented cars? Lessons learnt in three research centres.

2011

This paper provides an overview of the experiences using Highly Instrumented Cars (HICs) in three research Centres across Europe; Spain, the UK and Greece. The data collection capability of each car is described and an overview presented relating to the relationship between the level of instrumentation and the research possible. A discussion then follows which considers the advantages and disadvantages of using HICs for ND research. This includes the obtrusive nature of the data collection equipment, the cost of equipping the vehicles with sophisticated Data Acquisition Systems (DAS) and the challenges for data storage and analysis particularly with respect to video data. It is concluded th…

Skull and Encephalic Injuries Caused by Beach Umbrellas: Case Reports and Review of Literature

2016

This study reports two unusual cases of skull-encephalic injuries in bathers that were caused by violent impacts with beach umbrellas. The first case concerned a 36-year-old man who, while lying on a sun bed, was struck on his left temple by a beach umbrella, which had been blown away by a gust of wind. The second case concerned a six-year-old child who was struck on the right temporal region while he was playing on the sand. Both subjects died. A review of the literature was carried out. Various skull and brain injuries caused by several objects were found, but no injuries caused by beach umbrellas were detected. There were only cases of injuries caused by normal umbrellas. These cases sho…

Effects of Task-Irrelevant Cars on Judgments of Deceleration and Time-to-Contact During Car-Following

2012

Rear-end collisions represent over 25% of crashes with other moving vehicles (NHTSA, 2005). Factors that potentially contribute to such accidents include a driver’s ability to respond to a lead car’s deceleration and to estimate how much time remains until a collision would occur (DeLucia & Tharanathan, 2009). Prior research (Oberfeld & Hecht, 2008) showed that time-to-contact (TTC) judgments of approaching objects were influenced by task-irrelevant distractor objects. This finding has implications for rear-end collisions when drivers must detect a lead car’s deceleration amidst surrounding cars. However, Oberfeld and Hecht simulated a stationary observer rather than a moving obser…

Evaluating the citywide Edinburgh 20mph speed limit intervention effects on traffic speed and volume: A pre-post observational evaluation.

2021

Objectives Traffic speed is important to public health as it is a major contributory factor to collision risk and casualty severity. 20mph (32km/h) speed limit interventions are an increasingly common approach to address this transport and health challenge, but a more developed evidence base is needed to understand their effects. This study describes the changes in traffic speed and traffic volume in the City of Edinburgh, pre- and 12 months post-implementation of phased city-wide 20mph speed limits from 2016–2018. Methods The City of Edinburgh Council collected speed and volume data across one full week (24 hours a day) pre- and post-20mph speed limits for 66 streets. The pre- and post-sp…
