  1. 1. END-OF-LIFE FOR A QUARRY, WHAT IS THE ENVIRONMENTAL IMPACT?

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Kimia Golamian Yosaf Abadi; [2023-06-21]
    Keywords : Quarrying; Aggregates; Life cycle; Environmental impact; Restoration; Permit;

    Abstract : Aggregates products are the largest non-energy mining industry in the world, which is the most extracted materials after water. The most prevalent source of aggregates is from quarries, or mines that target the rock itself. READ MORE

  3. 2. Analysis of relatedness and genetic diversity in Swedish sheep breeds using medium density (50K) SNP data

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Krishani Devika Wijesinghe Sinhalage; [2023]
    Keywords : sheep; genetic diversity; population structure; inbreeding; runs of homozygosity; coat colour; MC1R;

    Abstract : The local Swedish sheep breeds belong to a group of sheep breeds known as North European short-tailed sheep breeds. Evaluation of genetic diversity, relatedness, and population structure of local breeds offers crucial metrics to prevent inbreeding depression, genetic erosion, and crossbreeding between locally adapted and exotic sheep breeds since these occurrences can have detrimental effects and ultimately lead to extinction.

  4. 3. Evaluation of five hardwood species from Zambia to produce fuel pellets for cooking purposes : Study with a single pellet press including pellet production, post production testing and X-ray examinations

    University essay from Karlstads universitet/Avdelningen för energi-, miljö- och byggteknik

    Author : Annika Silvennoinen; [2023]
    Keywords : Pelletizing; Pellet Production; Wood Species; X-Ray examinations; Pelletisering; Pelletstillverkning; Träslag; Röntgenundersökningar;

    Abstract : 81% of the population in sub-Saharan Africa relies on charcoal and firewood to cover their energy needs for cooking. In Africa charcoal is usually produced by burning tree in a traditional kilns and then the food is cooked with a carbon-fired stoves indoors. READ MORE

  5. 4. Population dynamics of the spruce bark beetle Ips typographus in forest conservation areas and the interaction with biodiversity and natural enemies

    University essay from SLU/Dept. of Ecology

    Author : Evelina Andersson; [2023]
    Keywords : spruce bark beetle; population dynamics; conservation areas; biodiversity; natural enemies; species richness; managed forests; woodland key-habitats; nature reserves;

    Abstract : Biodiversity is rapidly decreasing and in need of more conservation efforts. However, the tree-killing European spruce bark beetle, Ips typographus (L.), has made forest conservation controversial by affecting conservation areas and possibly adjoining managed forests, yet is still a keystone species leaving decaying wood promoting biodiversity.

  6. 5. 3D geospatial data requirements for simulating noise using the Nord2000 model: Case study of the impact of building façade types and roof configurations on simulated traffic noise levels

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Soraya Hosseinvash Azari; [2023]
    Keywords : Physical Geography; Ecosystem Analysis; noise simulation; traffic; Nord2000 model; building façade types; roof configurations; geospatial data; 3CIM; SoundPLAN; acoustic properties; urban areas; 3D city model; Earth and Environmental Sciences;

    Abstract : The European Union implements the Environmental Noise Directive (END), which offers a framework for evaluating and assessing environmental noise. All EU members are required to create strategic noise maps to inform the public about noise pollution and its effects. READ MORE
