Micronutrient deficiencies in the elderly - Could ready meals be part of the solution?
(2017-01-12)Micronutrient deficiencies contribute to many age-related disorders. One group at particular risk of micronutrient deficiencies is the elderly. Many elderly, such as the frail and those living in institutions, rely on ready ... -
Microparticles as tissue engineering scaffolds : manufacture, modification and manipulation
(2008-09)Tissue engineering, a field which focusses on the replacement, repair and regeneration of damaged or diseased tissue by the application of biomaterials, cells and associated biological molecules, has advanced rapidly due ... -
Microphysical aerosol parameters from multiwavelength lidar
(2005-03)The hybrid regularization technique developed at the Institute of Mathematics of Potsdam University (IMP) is used to derive microphysical properties such as effective radius, surface-area concentration, and volume ... -
Microphysical and optical properties of dust and tropical biomass burning aerosol layers in the Cape Verde region-an overview of the airborne in situ and lidar measurements during SAMUM-2
(2011-09-01)In the framework of the Saharan Mineral Dust Experiment (SAMUM) airborne High Spectral Resolution Lidar and in situ measurements of the particle size, aerosol mixing state and absorption coefficient were conducted. Here, ... -
Microphysical particle parameters from extinction and backscatter lidar data by inversion with regularization : experiment
(2000-04-20)We present effective radius, volume, surface-area, and number concentrations as well as mean complex refractive index of tropospheric particle size distributions based on lidar measurements at six wavelengths. The parameters ... -
Microphysical particle parameters from extinction and backscatter lidar data by inversion with regularization: simulation
(1999-04-20)A sensitivity study with an inversion scheme that permits one to retrieve physical parameters of tropospheric particle size distributions, e.g., effective radius, volume, surface-area, and number concentrations, as well ... -
Microphysical particle parameters from extinction and backscatter lidar data by inversion with regularization: theory
(1999-04-20)A method is proposed that permits one to retrieve physical parameters of tropospheric particle size distributions, e.g., effective radius, volume, surface-area, and number concentrations, as well as the mean complex ... -
Microphysical particle properties derived from inversion algorithms developed in the framework of EARLINET
(2016-10-12)We present a summary on the current status of two inversion algorithms that are used in EARLINET for the inversion of data collected with EARLINET multiwavelength Raman lidars. These instruments measure backscatter coecients ... -
Micropower Generation using Buckling Piezoelectric Elements
(2021-08-05)In recent years, piezoelectric materials and structures have gained significant attention for energy harvesting purposes. This attention can be attributed to the enhancement of low-power electronics and the high energy ... -
Microquasars : What do radio and X-ray observations tell us?
(2006-12-01)Microquasars, or X-ray binaries exhibiting radio jets, have been observed extensively at all wavelengths for the past decade or so. Primarily, they have been observed in the X-ray regimes and the radio. In this paper we ... -
MicroRNA expression profiles in pediatric dysembryoplastic neuroepithelial tumors.
(2016-01-30)Among noncoding RNAs, microRNAs (miRNAs) have been most extensively studied, and their biology has repeatedly been proven critical for central nervous system pathological conditions. The diagnostic value of several miRNAs ... -
MicroRNAs Regulate Ca 2+ Homeostasis in Murine Embryonic Stem Cells
(2023-07-28)MicroRNAs (miRNAs) are important regulators of embryonic stem cell (ESC) biology, and their study has identified key regulatory mechanisms. To find novel pathways regulated by miRNAs in ESCs, we undertook a bioinformatics ... -
Microstructural insight into inhalation powder blends through correlative multi-scale X-ray Computed Tomography
(2023-10-30)Dry powder inhalers (DPI) are important for topical drug delivery to the lungs, but characterising the pre-aerosolised powder microstructure is a key initial step in understanding the post-aerosolised blend performance. ... -
Microstructure Characterization and Battery Performance Comparison of MOF-235 and TiO 2 -P25 Materials
(2022-01-21)The growing interest in energy storage has led to the urgent need for the development of high-performance cathode electrodes. The commercialized materials MOF-235 and TiO2-P25 exhibit characteristics that may be suitable ... -
Microtubule dynamic instability: numerical simulation of microtubule transition properties using a Lateral Cap model
(1990)We present a numerical formulation for the dynamic instability of microtubules involving the stabilisation of growing microtubules by a single layer of tubulin-GTP, with GTP hydrolysis effectively coupled to tubulin-GTP ... -
Microvesicles and epithelial mesenchymal transition in the development of cancer
(2012-09-13)Microvesicles released by tumour cell lines are thought to play an important role in both extracellular matrix (ECM) invasion and evasion of the immune system. We have examined the role of MVs derived from a T cell line ...
