  1. 1. Women’s Political Representation during 2000–2021 : The Case of Mexico

    University essay from Linnéuniversitetet/Institutionen för statsvetenskap (ST)

    Author : Vanessa Necevska; [2024]
    Keywords : Mexico; Theory of Representation; Political Representation; Women’s political Representation; Women in national legislation.;

    Abstract : This qualitative case study focuses on the development of women’s political representation in national legislation, from 2000 to 2021 in Mexico. To examine the development of women’s political representation, this study will use Hanna Pitkin’s (1967) four interconnected diminutions of representation: formal, descriptive, substantive, and symbolic representation.

    University essay from Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Author : Kajsa Frost; [2023]
    Keywords : Polybrominated diphenyl ether; PBDE; BDE; hexabromocyclododecane; HBCDD; Temporal trends; Flame retardants; Baltic grey seal; Halichoerus grypus; Eurasian otter; Lutra lutra; Intestinal ulcers; BDE-47; BDE-99; BDE-100; BDE-153; BDE-154; Earth and Environmental Sciences;

    Abstract : Polybrominated diphenyl ethers (PBDE) and hexabromocyclododecane (HBCDD) are brominated flame retardants. These compounds are lipophilic, persistent and have been shown to bioaccumulate. READ MORE

  4. 3. Spatial distribution and thermo-climatic effects on the abundance of non-toxigenic Vibrio cholerae in Russia

    University essay from Södertörns högskola/Institutionen för naturvetenskap, miljö och teknik

    Author : Vadim Leonov; [2023]
    Keywords : V. cholerae; spatial analysis; climate change; heat wave; SatScan; vibriosis; Russia;

    Abstract : The identification of climate temperature-sensitive pathogens and infectious diseases is essential in addressing health risks resulting from global warming. Such research is especially crucial in regions where climate change may have a more significant impact like Russia. Recent studies have reasoned that the abundance of V. READ MORE

  5. 4. Long-term phosphorus trends in Swedish rivers and streams : widespread and persistent nutrient decline

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Sara Camiolo; [2021]
    Keywords : eutrophication; rivers; streams; phosphorus;

    Abstract : Phosphorus (P) is often considered the limiting nutrient for freshwater productivity because of its relevant role in regulating algal production and determining community composition. The concern for increasing anthropogenic P inputs registered since the last century has shaped environmental policies around the world to limit the effects of algal bloom (also known as eutrophication) in freshwater ecosystems through the establishment of maximum threshold nutrient concentrations.

  6. 5. Examining LUMBA UVES pipeline spectroscopy on giant and sub-giant stars of M67

    University essay from Uppsala universitet/Observationell astrofysik

    Author : Nikolaos Papakonstantinou; [2021]
    Keywords : methods: numerical; stars:abundances; stars: atmospheres; stars: statistics; stars:giants; stars:subgiants; stars: open clusters; stars: M67;

    Abstract : In this work, the efficiency of the LUMBA UVES pipeline for processing of spectroscopic observations is tested by use on 23 high-resolution spectra of the open star cluster M67. An abundance trend discovered by Gavel et al. (2019) concerning iron abundances of giant and sub-giant stars of that cluster is examined. READ MORE
