Ultrafiltration of Partially Degraded Starch Solution
(Dr.ingeniøravhandling, 0809-103X; 2002:87, Doctoral thesis, 2002)Desizing wastewater is largely responsible for the chemical oxygen demand (COD) load in the textile industry wastewater. A larger portion of COD comes from degraded starch in desizing wastewater. Removing the starch from ... -
Ultrafiltration of Saithe (Pollachius virens) Protein Hydrolysates and Its Effect on Antioxidative Activity
(Peer reviewed; Journal article, 2021)The whitefish industry generates a huge amount of rest raw material, which is currently wasted or underutilized in the production of low-value products such as animal feed. While fish muscle is the primary product of use ... -
Ultrahigh thermoelectric performance in Cu2−ySe0.5S0.5 liquid-like materials
(Journal article, 2017)Liquid-like thermoelectric materials have recently received heightened attentions due to their exceptional thermal and electrical transport properties. As a typical example, Cu2−ySe has good electrical transport properties ... -
Ultrahigh-pressure form of Si O2 glass with dense pyrite-type crystalline homology
(Peer reviewed; Journal article, 2019)High-pressure synthesis of denser glass has been a longstanding interest in condensed-matter physics and materials science because of its potentially broad industrial application. Nevertheless, understanding its nature ... -
Ultrasonic imaging as a means of monitoring gonadal development in lumpfish (Cyclopterus lumpus)
(Peer reviewed; Journal article, 2023)The commercial farming of juvenile lumpfish requires monitoring of gonadal development to achieve synchronized production. Conventional methods such as gonadosomatic index (GSI), sex hormone analyses, gonadal histology, ... -
Ultrasound and magnetic resonance imaging for group stratification and treatment monitoring in the transgenic adenocarcinoma of the mouse prostate model
(Journal article; Peer reviewed, 2020)Background:The transgenic adenocarcinoma of the mouse prostate (TRAMP) is a widelyused genetically engineered spontaneous prostate cancer model. However, both thedegree of malignancy and time of cancer onset vary. While ... -
Ultrasound and microbubble treatment for improved delivery of nanomedicine to tumours and the brain
(Doctoral theses at NTNU;2021:138, Doctoral thesis, 2021)The combined use of ultrasound and intravascular microbubbles, referred to as ultrasound and microbubble treatment, has emerged as a promising technique to enhance delivery of nanomedicine to tumours and the brain. Even ... -
Ultrasound and Microbubbles Increase the Uptake of Platinum in Murine Orthotopic Pancreatic Tumors
(Peer reviewed; Journal article, 2023)Objective Currently available cytotoxic treatments have limited effect on pancreatic ductal adenocarcinoma (PDAC) because desmoplastic stroma limits drug delivery. Efforts have been made to overcome these barriers by drug ... -
Ultrasound and microbubbles to beat barriers in tumors: Improving delivery of nanomedicine
(Peer reviewed; Journal article, 2021)Successful delivery of drugs and nanomedicine to tumors requires a functional vascular network, extravasation across the capillary wall, penetration through the extracellular matrix, and cellular uptake. Nanomedicine has ... -

(Peer reviewed; Journal article, 2021)Successful delivery of drugs and nanomedicine to tumors requires a functional vascular network, extravasation across the capillary wall, penetration through the extracellular matrix, and cellular uptake. Nanomedicine has ... -
Ultrasound as a non-invasive tool for monitoring reproductive physiology in female Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2018)Aiming to explore ultrasound technology as a noninvasive method for maturation monitoring, we compared ultrasound observations and measurements in female Atlantic salmon (Salmo salar) during the last year before ovulation ... -
Ultrasound as a noninvasive tool for monitoring reproductive physiology in male Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2019)We examined the potential for ultrasound as a noninvasive tool for maturation monitoring in Atlantic salmon (Salmo salar) males. Ultrasound examination and measurements were compared to common practices for maturation ... -
Ultrasound Beamforming based on Deep Learning
(Master thesis, 2020)Stråleforming blir brukt av enheter som tar opp eller sender signaler med flere enn én kanaler for å gi sterkere signalstyrke i en gitt retning. Innen ultralyd kan bedre algoritmer for stråleforming gi økt bildekvalitet, ... -
Ultrasound for the delivery of a nanocarrier across biological barriers in tumors: impact of cavitation and acoustic radiation force
(Doctoral theses at NTNU;2020:56, Doctoral thesis, 2020)Ultrasound for the delivery of a nanocarrier across biological barriers in tumors: impact of cavitation and acoustic radiation force Although conventional chemotherapy is the still one of the most important treatment ... -
Ultrasound Improves the Delivery and Therapeutic Effect of Nanoparticle-Stabilized Microbubbles in Breast Cancer Xenografts
(Journal article; Peer reviewed, 2017)Compared with conventional chemotherapy, encapsulation of drugs in nanoparticles can improve efficacy and reduce toxicity. However, delivery of nanoparticles is often insufficient and heterogeneous because of various ... -
Ultrasound in Imaging and Delivery of Nanomedicine in Cancer Tissue
(Doctoral thesis at NTNU;2015:27, Doctoral thesis, 2015)Nanotechnology in therapy of solid tumors is a strategy where the cytotoxic drugs are encapsulated into nano-sized particles. It is expected that therapy using nanomedicine will result in both increased specificity of the ... -
Ultrasound radiation force transport of drugs in tumors
(Master thesis, 2013)Chemotherapy effectiveness not only depends on drug penetration extent in target tissues or tumor cells, but also depends on drug suppression extent by the normal tissues and cells. Ultrasound acts as an important role to ... -
