  1. 1. Low-concentration Bacteria Separation from Whole Blood through a Slanted Filter in a Centrifuge Tube

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Kaiyang Zeng; [2023]
    Keywords : sepsis; bloodstream infection; bacteria; blood; separation; centrifuge; sedimentation; filter; falcon tube; sepsis; blodsmittsamhet; bakterier; blod; separation; centrifugering; sedimentering; filter; falcon-rör;

    Abstract : Sepsis characterized by severe bloodstream bacterial infection that results in high mortality rates and medical expenses has become a global healthcare challenge. The current clinical sepsis diagnosis is based on blood culture and requires a long waiting time, delaying effective treatments. READ MORE

  3. 2. Investigation of acoustic whole blood plasmapheresis for minimization of endogenous blood loss in neonatal care

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Tobias Lindgren; [2021]
    Keywords : Acoustophoresis; peristaltic pump; flow cytometry; plasmapheresis; whole blood; extremely premature infants; Microfluidics; Technology and Engineering;

    Abstract : Early erythrocyte transfusion is common in infants born extremely premature. Research has shown that these children are at greater risk of morbidity later in life, and that iatrogenic blood loss from blood sample analysis is one of the contributing factors to the need for transfusions.

  4. 3. Development of a Near Infrared Spectroscopy Model for Prediction of Fibre Compounds in Alfalfa

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Christina Andersen; [2020]
    Keywords : alfalfa; lucerne; medicago sativa; green protein powder; NIR; near infrared spectroscopy; model development; matlab; PLS; partial least squares; PCA; principal component analysis; SNV; standard normal variate; fibre prediction; TDF; total dietary fibre; applied microbiology; teknisk mikrobiologi; Technology and Engineering;

    Abstract : Background: This project investigates if it is possible to develop a calibration model from near infrared (NIR) spectroscopic measurements, for determination of the amount and type of fibre fractions within protein powder produced from the legume alfalfa, without performing wet experiments. Alfalfa is also known as Medicago sativa and lucerne, but is in this project further referred to as alfalfa. READ MORE

  5. 4. A study of the stability of vitamin 25[OH]D2 and 25[OH]D3

    University essay from Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Author : Anna Kellström; [2020]
    Keywords : Vitamin D; 25-hydroxyvitamin D; pre-analytical relevance; HPLC-MS MS; stable; freeze-thaw cycles; light sensitivity; quality assurance;

    Abstract : During the industrialization of the 19th century the negative health effects of vitamin D was discovered as children in the cities developed osteomalacia or more commonly known as rickets caused by vitamin D deficiency. Vitamin D is produced in the skin from 7-dehydrocholesterol during sun-exposure and enhances intestinal phosphor and calcium absorption thus enhancing the bone remodeling process. READ MORE

  6. 5. A study of classification methods to identify sound signals of a washing machine

    University essay from Lunds universitet/Matematik LTH

    Author : Chiharu Kazama; [2019]
    Keywords : Fourier transform; DFT; FFT; STFT; sounds classification; Keras; supervised learning; neural network; Random search; machine learning; signal processing; Mathematics and Statistics;

    Abstract : Syftet med denna uppsats är att undersöka och klassificera ljud från en tvättmaskin. Ett tvättmaskinsprogram har olika faser, t ex vattenfyllning, tvättning, centrifugering, etc. Varje fas har ett eget ljud, därför kan vi anta vilken av faserna det är från ljudet, även om vi inte ser tvättmaskinen.
