The distribution of dispersed oil droplets at several DOR were evaluated and it was observed that oil droplets become smaller with increasing DOR. In addition, the acute toxicity analysis of developed formulations against zebra fish (Danio rerio) confirmed their non-toxic behavior with LC50 values higher than 400 ppm after 96 h. Overall, the proposed new blends/formulations could effectively substitute the toxic and unsafe chemical dispersants.Plastic pollution is a new, pressing, environmental topic. Microplastics are considered contaminants of emerging concern and, consequently, microplastic research has grown exponentially in the last decade. Here, current knowledge regarding the impacts of micro- and nanoplastics on terrestrial plants and aquatic macrophytes is discussed, with a special focus on adsorption, uptake and toxicological effects. Our review reveals that a range of plants and macrophytes can adsorb or internalise plastic particles. Both processes depend on particle characteristics such as size and charge, as well as plant features including a sticky or hydrophobic surface layer. This finding is of concern given that plants and aquatic macrophytes are at the bottom of food webs and are a crucial component of the human diet. Therefore, there is a critical need for improved understanding of adsorption, uptake and impacts of micro- and nanoplastics, and the consequences thereof for trophic transfer, food safety and security. Also, a range of stress responses have been observed for many plant and macrophyte species after both short and long-term exposures to plastic particles. Given that some plastic particles can affect plant productivity, we surmise that plastic particles may potentially impact ecosystem productivity and function. Here we present a synthesis and a critical evaluation of the state of knowledge of micro- and nanoplastics and plants and macrophytes, identifying key questions for future research.The aim of this study was to compare differences in comorbidity between immigrants and Finnish-born controls, and to examine the treatment received by immigrants with PTSD. Our original data included all the immigrants living in Finland by the end of 2010 and matched controls. For this study, we selected individuals who had received a diagnosis of PTSD during 2010-2015 (immigrants n = 754, Finnish-born controls n = 311). We compared the frequency of different comorbid conditions between immigrants and natives. Multinomial logistic regression was used to predict categorized treatment intensity with the region of origin and length of residence among the immigrants. Psychiatric comorbidity was much more extensive among the Finnish-born controls than among immigrants. Immigrants from Africa and the Middle East more often received treatment of low intensity compared with immigrants from Western countries. The length of residence was associated with more frequent treatment. The important differences in comorbidity and background characteristics between immigrants and natives should be taken into account in planning treatment guidelines for PTSD. The disparities in treatment intensity across different immigrant groups indicate a need to improve the services for immigrants with PTSD.In helicopter emergency medical services, HEMS, coagulopathy presents both in trauma (e.g. consumption of coagulation factors) and non-trauma cases (e.g. anticoagulant use). Therefore, in HEMS coagulation measurements appear promising and Prothrombin Time (PT) and derived INR are attractive variables herein. We tested the feasibility of prehospital PT/INR coagulation measurements in HEMS. This study was performed at the Dutch HEMS, using a portable blood analyzer (i-Stat®1, Abbott). PT/INR measurements were performed on (hemodiluted) author's blood, and both trauma- and non-trauma HEMS patients. Device-related benefits of the i-Stat PT/INR system were portability, speed and ease of handling. Limitations included a rather narrow operational temperature range (16-30 °C). PT/INR measurements (n = 15) were performed on hemodiluted blood, and both trauma and non-trauma patients. The PT/INR results confirmed effects of hemodilution and anticoagulation, however, most measurement results were in the normal INR-range (0.9-1.2). We conclude that prehospital PT/INR measurements, although with limitations, are feasible in HEMS operations.Research suggests that parents play a critical role in introducing technology to their young children and that parent-child joint engagement with technology can improve learning and social outcomes. The present mixed-methods study extends the current literature by directly observing the interactions of 30 parents with their infant or toddler child (ages 12-24 months) while introducing and engaging with familiar and novel mobile technologies. Qualitative analysis of observations yielded five overarching themes that described key content of parent-child interactions. Subthemes further clarified the types of verbal interactions of the child and of the parent, as well as issues of control over the device, activities and selection choices, skill needs/supports, and interest in the interactions. Developmental milestones and parental surveys contributed to the understanding of developmental change and family media use. Familiarity with the device influenced frequencies of identified themes with greater likelihood for fewer interactions, scaffolds and more passive screen activities with familiar technology. More varied verbal scaffolding was related to higher developmental scores. CC885 Physical scaffolding was provided infrequently, despite limited skill in the children. Counter to parental expectations, initiating and sustaining interest even for a short period of time was challenging in some cases. Outcomes suggest that parents engage in a wide array of relevant scaffolds with variability across individuals and child age. Overall, the study provides a rich and complex description of interactions and behaviors when parents introduce mobile devices to their infants and toddlers.

Participation in employment by individuals with autism spectrum disorders (ASD) remains restricted despite their high motivation and evident abilities. Challenges to employment result from personal characteristics and environmental barriers. This phenomenological research explores the accessibility of a competitive work environment according to the perceptions of adults with ASD.

We conducted in-depth interviews with 19 employees with ASD, followed by a thematic content analysis. Three themes emerged (a) the employees' motivation for employment, (b) challenges and abilities at work, and (c) workplace accessibility (types of accommodations, implementation process).

The findings contribute a classification of accommodations that addresses the core characteristics of autism-challenges as well as abilities and motivations for employment. Four types of accommodations were identified job-performance communication, attitudes and interpersonal communication, daily workplace routines, and physical and sensory environments.
