  1. 1. Pine production comparison : production potential of Loblolly pine (Pinus taeda) and Slash pine (Pinus elliottii) in the southeastern USA in relation to initial density and forest management

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Forest Resource Management

    Författare :Åsa Ramberg; [2019]
    Nyckelord :Loblolly pine; Slash pine; Scots pine; management intensity; planting density;

    Sammanfattning : The southeastern (SE) United States (US) produces more industrial timber than any other region in the world. Pine plantations in the southern US have increased from 1.8 million acres (728,400 ha) in the beginning of the 1950’s to 32 million acres (13 million ha) in the beginning of the 21st century, and cover 17 % of the forest land.

  2. 2. Dispersion management and characterization of ultrashort laser pulses for the optimization of parametric processes

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Axel Elfving; [2019]
    Nyckelord :frequency resolved optical gating; optical parametric amplification; difference frequency generation; nonlinear optics; laser pulse compression; lasers; optics; Technology and Engineering; Physics and Astronomy;

    Sammanfattning : This thesis set out to continue the development of a short-wave infrared (SWIR) optical parametric amplifier (OPA). The system is based on a Yb-ber chirped pulse amplification (CPA) laser delivering 400 fs long pulses, centered around 1030 nm, at 200 kHz repetition rate and 40 W average power. LÄS MER

    Sammanfattning : After the sewage wastewater is collected from different households and directed to the treatment plants, it goes through several processes, which are physical, chemical and biological. The different processes remove the contaminant, and produce a semi-solid material named sludge. Sludge has a huge amount of liquid. LÄS MER

  4. 4. Att leva med långvarig ryggsmärta : En litteraturöversikt om individers upplevelser

    Kandidat-uppsats, Ersta Sköndal högskola/Institutionen för vårdvetenskap; Ersta Sköndal högskola/Institutionen för vårdvetenskap

    Författare :Sofie Eriksson; Sabine Murkisch; [2019]
    Nyckelord :chronic pain; back pain; low back pain; quality of life; coping; experience; kronisk smärta; ryggsmärta; ländryggssmärta; livskvalitet; hantering; upplevelser;

    Sammanfattning : Bakgrund:  Långvarig smärta är en subjektivt ihållande smärta som pågår i mer än tre månader. Smärtan återkommer i skov där lokalisation, intensitet och smärttyp kan skilja sig åt mellan episoderna. Inom långvarig smärta är ryggsmärta den vanligast förkommande och är lokaliserad till ländrygg-, skulder- eller nacksmärtor. LÄS MER

  5. 5. The Po Delta Biosphere Reserve: Management challenges and priorities deriving from anthropogenic pressure and sea level rise

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Damiano Vesentini; [2019]
    Nyckelord :geography; GIS; environmental pressure; water quality; nutrient accumulation; rising sea level; climate change; value for conservation; Earth and Environmental Sciences;

    Sammanfattning : The Po Delta Biosphere Reserve is located in Northern Italy and has attained recognition by UNESCO in 2015 due to its unique natural and cultural value. The reserve covers an area of approximately 140 000 hectares, supporting a human population of 118 000, as well as a complex mosaic of ecosystems, which are found in this transitional waters landscape.
