Presence of plastic particles in waterbirds faeces collected in Spanish lakes
2017
Plastic intake by marine vertebrates has been widely reported, but information about its presence in continental waterfowl is scarce. Here we analyzed faeces of waterbirds species (European coot, Fulica atra, mallard, Anas platyrhynchos and shelduck, Tadorna tadorna) for plastic debris in five wetlands in Central Spain. We collected 89 faeces of shelduck distributed in four lakes, 43.8% of them presented plastic remnants. Sixty percent of 10 faeces of European coot and 45% of 40 faeces of mallard contained plastic debris. Plastic debris found was of two types, threads and fragments, and were identified as remnants of plastic objects used in agricultural fields surrounding the lakes. Differe…
Future Development of an Energy-Efficient Electric Scooter Sharing System Based on a Stakeholder Analysis Method
2023
E-scooters as a new form of mobility are gaining more and more popularity. This popularity results from the flexibility of this mode of transport, but above all from the positive impact on the natural environment through the much higher energy efficiency of an e-scooter compared to a motor vehicle (according to the literature the rate is 2 km per kWh equivalent for a motor vehicle and the range is 90–100 km per kWh in the case of an e-scooter). This paper introduces a discussion on the future development of an energy-efficient electric scooter sharing system based on stakeholder analysis methods. The implementation of the e-scooter sharing system involves linking several areas of human acti…
Mikromobilitātes klimata paplašināšanās iespējas Ziemeļvalstīs - iespējas un draudi
2020
Anton Martikainen rakstītajā maģistra darbā tiks pētīta mikromobilitāte, kas specializējas e-skūteros – šobrīd esošs fenomens, kas aizsākās 2018. gadā Amerikas Savienotajās Valstīs un ienāca Eiropā 2019. gada sākumā. Darba teorētiskā pieeja ir balstīta uz teoriju, kas saistīta ar paplašināšanos - mobilitāte kā pakalpojums un trešo pušu loģistikas teorija, kurai ir svarīga loma e-skūteru nozarē. Mikromobilitāte ir kļuvusi par aktuālu tēmu visā pasaulē, mainot veidu, kā cilvēki pārvietojas. Autors savā pētījumā definēs mikromobilitāti, analizēs galvenos tirgus dalībniekus un precīzi norādīs uz iespējām un draudiem un, kā tos redz iekšējās un ārējās iesaistītās puses. Darba izstrādes laikā tik…
Association of oral lichen planus with hepatic disorders and hepatocellular carcinoma:systematic review and meta-analysis
2023
Oral lichen planus (OLP) is a prevalent autoimmune chronic inflammatory disease of unknown etiology. The importance of the association between hepatic disease and OLP lies in the fact that many of these disorders (HC, HB, cirrhosis, hepatic steatosis) behave as risk factors for hepatocellular carcinoma. We searched PubMed, Embase, Web of Science, and Scopus for studies published before January 2022. We evaluated the quality of studies (Joanna Briggs Institute tool). We performed meta-analyses, investigated the heterogeneity between studies, and we also carried out subgroups, meta-regression, and small-study effects analyses. 146 studies (21,187 patients) were included in this study. Our stu…
