  1. 1. Investigation of flux dependence on viscosity in ultrafiltration

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Peter Bourghardt; [2023]
    Keywords : ultrafiltration; viscosity; molasess; konjac glucomannan; comsol; LabStak M39; membrane; filtration; chemical engineering; Chemistry;

    Abstract : This project aims to compare the effect of viscosity on flux for high viscosity liquids. The performance of two different viscous solutions was studied in a plate-and-frame membrane module. READ MORE

  3. 2. Integrating horticultural and arable crops : a sustainable way to increase vegetable production in Scania?

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Stina Helena Mortensen; [2022]
    Keywords : Horticulture; agriculture; vegetables; crop rotation; crop sequence; diversification; integration; ecosystem services; farmers’ attitudes;

    Abstract : Modern arable production is associated with a highly homogenous landscape with few cultivated species and is relying heavily on external chemical inputs. Intensive vegetable production, on the other hand, is associated with environmental costs such as increased risk of nutrient leaching and loss of soil organic matter. READ MORE

  4. 3. Effects of plant-fungal interactions on volatile emission of Hordeum vulgare and aphid preference

    University essay from SLU/Dept. of Ecology

    Author : Bina Johansson; [2022]
    Keywords : volatile organic compounds; chemical communication; Trichoderma atroviride; Fusarium graminearum; Rhopalosiphum padi; biological control;

    Abstract : Barley is one of the most economically important cultivated crops in the world. However, barley is a host for many insect pests and plant pathogenic fungi which is a threat to the production. Rhopalosiphum padi is an economically important insect pest that leads to large economical losses in agricultural crops such as barley. READ MORE

  5. 4. Using Sentinel-2 Satellite Images to Estimate Traits of Forage Grasslands

    University essay from SLU/Dept. of Agricultural Research for Northern Sweden

    Author : Niklas Zeiner; [2021]
    Keywords : Remote sensing; Forage grasslands; Sentinel-2; Dry matter yield; Canopy average height; Total leaf chlorophyll content; Partial least squares; Support vector machines;

    Abstract : In this project, regression models based on data from field measurements and spectral information extracted from satellite imagery were used to estimate traits of forage grasslands; dry matter yield, canopy average height and total leaf chlorophyll. Four fields at SLUs Röbäcksdalen field station were sampled on 22 occasions and a total of 198 samples, including measurement of the highest plant, canopy height, leaf chlorophyll content, canopy spectral reflectance and biomass were collected.

  6. 5. Bekämpning av rotgallnematodarterna Meloidogyne hapla, M. chitwoodi och M. fallax : grödors naturliga resistens som alternativ till svartträda?

    University essay from SLU/Dept. of Ecology

    Author : Jesper Fritzson; [2020]
    Keywords : rotgallnematoder; naturlig resistens; fånggröda; bekämpning; oljerättika; tagetes;

    Abstract : Växtparasitära nematoder börjar bli ett allt större problem världen över där de orsakar stora ekonomiska skador. Bekämpningen av dessa blir svårare allt eftersom kemiska bekämpningsmedel mot nematoder mer och mer globalt förbjuds på grund av dess toxiska påverkan på bland annat applicerande lantbrukare samt ekosystem runtom och i nematodinfekterade fält.
