1. 1. Distribution and transport of microplastics and metals in sewage sludge-amended agricultural soil : a Comparative study between microplastics copper, cadmium, and nickel

   University essay from SLU/Dept. of Soil and Environment

   Author : Nora Ottander; [2022]
   Keywords : Bioturbation; advective transport; earthworm; Aporrectodea longa;

   Abstract : This thesis investigated the vertical transport of microplastics and metals in agricultural soil after sewage sludge application. Sewage sludge is commonly used in agriculture for adding nutrients and carbon to improve the soil quality. READ MORE

3. 2. CFD Analysis of Cold Stage Centrifugal Pump for Cooling of Hot IsostaticPress with Validation Case Study

   University essay from KTH/Mekanik

   Author : Shane Hereford; [2017]
   Keywords : CFD; HIP; Quintus Technologies; Centrifugal pump; pump curve;

   Abstract : Hot isostatic pressing (HIPing) has been a growing material treatment process for performance part manufacturingfor over 50 years. This process of using an inert gas at high temperature and pressure to densifymaterials leads to vastly improved material properties by removing pores and other micro- aws. READ MORE

4. 3. Effect of soil tillage system and straw retention on soil aggregation and water capacity

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

   Author : Emma Lindqvist; [2015]
   Keywords : soil; tillage; structure; aggregation; straw; water capacity;

   Abstract : Arable land supplies food and it is therefore important to develop the production and land-use in a sustainable way. To grow crops for food should be both economical and environmentally sustainable and the soil structure and quality should be taken in consideration when cultivating our land. READ MORE

5. 4. Control strategies and inspection methods for welded part

   University essay from Avdelningen för maskin- och materialteknik

   Author : Divyank Baradi; [2013]
   Keywords : Visual inspection; WPS; impressions; throat size gauge; radius gauge; liquid penetrant test; magnetic particle testing; eddy current; radiography; ultrasonic PAUT TOFD ; thermography; control plan; cost per hour.;

   Abstract : Present and future demonstrator designs were used to demonstrate the quality assurance of welds. The NDT methods tested on prototype demonstrator parts are: visual inspection, radius gauges, throat size gauge, liquid-penetrant testing, magnetic particle testing and ultrasonics with pulse echo and phased array.

6. 5. 3D-printing of undisturbed soil imaged by X-ray

   University essay from SLU/Dept. of Soil and Environment

   Author : Matthias Bacher; [2013]
   Keywords : soil; macropores; 3D-printing; X-ray;

   Abstract : An artificial soil pore network can help to analyse preferential macropore flow which is important for pollutant leaching and degradation in the environment. Reproducing soil macro pores in an artificial, durable material offers the opportunity of repeating experiments in contrast to real soil pore networks. READ MORE
