Alternaria Mycotoxins in Food and Feed: An Overview

2017

Alternariais one of the major mycotoxigenic fungal genera with more than 70 reported metabolites.Alternariamycotoxins showed notably toxicity, such as mutagenicity, carcinogenicity, induction of DNA strand break, sphingolipid metabolism disruption, or inhibition of enzymes activity and photophosphorylation. This review reports on the toxicity, stability, metabolism, current analytical methods, and prevalence ofAlternariamycotoxins in food and feed through the most recent published research. Half of the publications were focused on fruits, vegetables, and derived products—mainly tomato and apples—while cereals and cereal by-products represented 38%. The most studied compounds were alternario…

Stress at Work and Physical Load in Professional Sport

2018

Various professional sports have reached a high level of development. Stress at athletes’ work partly characterizes quality of psycho-emotional work environment. Psychological effects caused by stress frequently change into physical effects. At the same time, it should be noted that athletes do not receive adequate attention from the occupational health and safety point of view. The aim of the research was to investigate influence of work stress and physical load on professional volleyball athletes during trainings in comparison with volleyball competitions. The results reveal that the volleyball players are generally exposed to physical load (94%) and 82% - to work stress and other psycho-…

An Integrated Approach to Mandarin Processing: Food Safety and Nutritional Quality, Consumer Preference, and Nutrient Bioaccessibility

2017

Mandarins are a member of the Citrus genus and are the focus of growing commercial interest, with satsuma mandarins (Citrus unshiu) and the common mandarin (Citrus reticulata Blanco) being the most important mandarin varieties. The possible health benefits and functional properties of those fruits are often associated with the antioxidative function of vitamin C, carotenoids, and phenolic compounds. While most mandarins are consumed fresh, many are processed into juices (mostly cloudy), usually via thermal processing which can lead to the creation of off-flavors and may diminish nutritional quality. The aim of this review is to summarize the most significant and recent information on the sa…

In this review, state-of-the-art evidence on the relationship between cannabis use, traffic crash risks, and driving safety were analyzed. Systematic reviews, meta-analyses, and other relevant papers published within the last decade were systematically searched and synthesized. Findings show that meta-analyses and culpability studies consistently indicate a slightly but significantly increased risk of crashes after acute cannabis use. These risks vary across included study type, crash severity, and method of substance application and measurement. Some studies show a significant correlation between high THC blood concentrations and car crash risk. Most studies do not support this relationshi…

Comparison of the Antibiotic-Resistant <i>Enterobacteriaceae</i> Content in Conventional, Organic and Fresh-Cut Vegetables Sold in Valenc…

2020

Bacterial content of fresh vegetables that are often eaten raw represents a risk factor for consumers, and the presence in these produce of antibiotic-resistant bacteria constitutes an additional food safety concern. We have compared the Enterobacteriaceae content, as well as the antibiotic resistances of bacterial isolates, in samples of different types of fresh vegetables (conventional an organic produce, fresh-cut vegetables and prepared salads) marketed in Valencia (Spain) in order to find possible differences among these vegetable types. Bacterial isolation, identification and resistance assays to eleven relevant chemotherapeutics agents were performed according to standard microbiolog…

Modelling safety climate in the prediction of levels of safety activity

1998

Abstract This study examined the architecture of the relationships between components of organizational safety climate, including employee attitudes to safety issues and perceptions of the work environment, and related this to self-reported levels of safety activity. Data were collected from a large multinational manufacturing organization by questionnaire. A total of 915 valid questionnaires were returned and formed the basis for structural equation modelling and subsequent analyses. These data showed that a common structure, or architecture, of attitudes to safety issues and perceptions of the work environment could be constructed that explained levels of safety activity. The strength of …

Exploiting Semantic Trajectories Using HMMs and BIM for Worker Safety in Dynamic Environments

2020

International audience; Understanding dynamic behaviors of moving objects using positioning technologies for construction safety monitoring is still an open research issue. One task; that is a small subset in the widespread field of objects dynamics is the enrichment of the location data of users with the semantic information for studying their mobility patterns in the context of the environment. However, incorporating the semantics related to the environment gets complex in case of the dynamic construction sites where the site spaces are kept evolving with time. For instance, new walls and infrastructure supports are added often on sites, while others are detached. Similar situations open …

A Hybrid Virtual-Augmented Serious Game to Improve Driving Safety Awareness

2018

The use of 3D virtual content and Augmented Reality (AR) in certain applications allows designing tools and serious games that are more attractive to the potential users. Focusing on the area of learning and education, these technologies can be adapted to the requirements of the application that needs to be developed, to the available devices on which they are expected to run and also to the learning content. However, in most applications only a single interaction paradigm and a single visualization mode is used, restricting the potential benefits of the system. In this paper, we propose a software application designed to improve driving safety awareness and learning for both adults and chi…
