The methods of measuring the heat capacity of materials by differential scanning calorimetry (DSC) are presented and discussed. The principles of temperature modulated DSC are outlined and the possibilities and limits of the method are discussed.
This communication introduces a novel scheme for the treatment of free edge supports in the analysis of beams by using the discrete singular convolution (DSC) algorithm. Accommodating free edges has been a challenging issue in the DSC analysis of beams, plates, and shells. An iteratively matched boundary (IMB) method is proposed to overcome the difficulty. Numerical experiments are carried out ...
Extrinsic and intrinsic characterizations are given for the class DSC(K) of differences of semi-continuous functions on a Polish space K, and also decomposition characterizations of DSC(K) and the class PS(K) of pointwise stabilizing functions on K are obtained in terms of behavior restricted to ambiguous sets. The main, extrinsic characterization is given in terms of behavior restricted to som...
The deep superior colliculus (DSC) integrates multisensory input and triggers an orienting movement toward the source of stimulation (target). It would seem reasonable to suppose that input of an additional modality should always increase the amount of information received by a DSC neuron concerning a target. However, of all DSC neurons studied, only about one half in the cat and one-quarter in...
Objective. To investigate the efficacy and safety of traditional Chinese medicine Duliang soft capsule (DSC) in prophylactic treatment for patients with chronic daily headache (CDH). Methods. A multicenter, double-blind, randomized, placebo-controlled clinical study was conducted at 18 Chinese clinical centers. The participants received either DSC or placebo for 4 weeks. The primary efficacy me...
INTRODUCTION: Dynamic-Susceptibilty-Contrast Magnetic Resonance Imaging (DSC-MRI) has been established as a reliable method to investigate hemodynamic changes in cerebral perfusion. Compared to PET and SPECT, DSC-MRI often overestimates of the amount of cerebral blood flow (CBF) and cerebral blood volume (CBV), which is due to the high sensitivity of DSC-MRI to large vessels [1]. To improve the...
The roots of Dipsacus asper (DA) have been used as a tonic and analgesic agent in traditional Chinese medicine for the treatment of osteoporosis, low back pain, knee pain, and as an anti-inflammatory agent. Few studies have reported pharmacological gastric activities. In this study, we investigated the effects of dipsacussaponin C (DSC) and 70% ethanol and water extracts of DA on gastritis and ...
The ability of stem cells to self-renew as well as their multilineage differentiation potential makes them ideal candidates for skin regeneration strategies. Mesenchymal stem cells residing in human adult dermis, in contrast to adipose tissue, have not yet been described. The objective of this study was to determine the stemness and chemokine-mediated homing potential of dermal stromal cells (D...
Differential scanning calorimetry (DSC) is used to evaluate the thermal stability and reversibility after heat treatment of transitions associated with various cellular components of Escherichia coli and Lactobacillus plantarum. The reversibility and the change in the thermal stability of individual transitions are evaluated by a second temperature scan after preheating in the DSC to various te...
