  1. 1. Shallow near-surface lapse rates and their connection to glacier meteorology on Storglaciären and Rabots glaciär, Northern Sweden

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Moon Taveirne; [2022]
    Keywords : Temperature lapse rate; glacier meteorology; near-­surface lapse rate; ablation gradient;

    Abstract : Glacier melt is strongly impacted by climate and meteorology. Temperature lapse rates are used to model glacier melt, and the accuracy of the spatial distribution of modelled melt can be impacted by the lapse rate used in modelling. Additionally, the observed spatial distribution of melt is highly temporally variable. READ MORE

  3. 2. The digesta passage rate among dairy cows with different abilities to consume large quantities of roughage : its impact on the milk production, and the reliability of the chemical fibre marker

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Maria Elisabeth Eklund; [2020]
    Keywords : chemical markers; chromium; chromium mordanted fibre; cobalt; concen-trate level; EDTA; iNDF; mean re-tention time; ethylenediaminetetraacetic acid; forage consumption; indigestible neutral detergent fibre; liquid digesta phase; MRT; rumen evacuation; sol;

    Abstract : The objectives of the present master thesis were to investigate the passage rate among lactating Holstein and Swedish red dairy cows to investigate the hypotheses of: 1) The cows’ individual total mean retention time (TMRT) has a negative relationship to the cows’ individual forage intake capacity. 2) A reduced TMRT contributes to a reduced feed efficiency, but a higher milk yield.

  4. 3. Våm-pH hos mjölkkor : jämförelse av mättekniker och pH-förändring i samband med foderintag

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Veronica Furenbäck; [2019]
    Keywords : nätmagens pH; våmacidos; SARA; LRCpH; eBolus; buffring; salivflödeshastighet; tuggaktivitet; idissling; peNDF; partikellängd; sortering;

    Abstract : Våmmens pH hos mjölkkor varierar under dygnet och mikroberna i våmmen behöver ett pH mellan 6-6,5 för att fungera optimalt. Normalt hålls våm-pH stabilt genom att kon absorberar flyktiga fettsyror (VFA) till blodet och den viktigaste mekanismen är saliven vilket har en buffringsförmåga då den innehåller bikarbonat och vätefosfatjoner.

  5. 4. Indoor Air Pollution, Passive Ventilation Strategies and Thermal Comfort in Nepal

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Marianne Löwgren; [2019]
    Keywords : Energy poverty; Solid biomass fuels; Improved cooking stoves; Indoor air pollution; Carbon monoxide; Vernacular architecture; Passive ventilation; Air exchange rate; Indoor air quality; Thermal comfort; Operative temperature; Sustainable societal development; Social Sciences; Technology and Engineering;

    Abstract : Indoor Air Pollution (IAP) resulting from indoor burning of solid biomass fuels in poorly ventilated kitchens is a severe health risk in parts of the world where energy poverty is prevalent. Passive ventilation, i.e. taking advantage of naturally induced airflow has been suggested as crucial in reducing IAP levels below safe limits. READ MORE

  6. 5. Assessment of forcing mechanisms on net community production and dissolved inorganic carbon dynamics in the Southern Ocean using glider data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Julia Schütt; [2017]
    Keywords : net community production; geography; physical geography; dissolved inorganic carbon; Southern Ocean; Earth and Environmental Sciences;

    Abstract : In the Subantarctic Zone of the Southern Ocean, a combination of physical forcings, chemical solubility and biological fixation is controlling the carbon uptake and thus the role the Southern Ocean is playing in the remediation of global climate change. Therefore, it is necessary to understand the mechanisms controlling oceanic carbon budgets and to quantify biological uptake rates to make reliable future climate predictions. READ MORE
