This study develops a novel composite phase change material (PCM) based onparaffin/hydrophobic expanded perlite and exfoliated graphene nanoplatelets as heat transferpromoter. The experimental analysis was systematically carried out on fabrication,characterization and testing the thermal storage properties of composite PCM. The micro-morphology characteristics of composite PCM s...
The three-dimensional (3D) expanded graphite-carbon nanotube (EG-CNT) nanocomposite was prepared by in situ growing CNTs between graphite layers in thermally expanded graphite. The morphology and microstructure of the nanocomoposite were characterized by SEM, TEM, Raman and XRD analyses, respectively. The results show that intimately contacted EG-CNT interface has been formed within the multila...
Phage lambda lyses the host Escherichia coli at a precisely scheduled time after induction. Lysis timing is determined by the action of phage holins, which are small proteins that induce hole formation in the bacterium's cytoplasmic membrane. We present a two-stage nucleation model of lysis timing, with the nucleation of condensed holin rafts on the inner membrane followed by the nucleation of ...
43 44 We present a new rough-surface thermophysical model (Advanced Thermophysical Model or 45 ATPM) that describes the observed directional thermal emission from any atmosphereless 46 planetary surface. It explicitly incorporates partial shadowing, scattering of sunlight, 47 selfheating and thermal-infrared beaming (re-radiation of absorbed sunlight back towards the 48 Sun as a result of surfa...

abstract: adequate processing of tissues before histologic slices is necessary for preparation of proper histologic sections in animal studies. fixation is one of the most important and early laboratory stages of tissue processing. amount of penetration time of fixator material, into deep layers and central portions of hard tissues, is important factor for prevention of cell lysis. the purpose ...
BACKGROUND Menstruation is associated with a striking increase in matrix metalloproteinase (MMP) activity. However, it is still unknown whether the level of MMP activity correlates with the amount of menstrual bleeding. METHODS We used histochemistry to investigate the degradation of the extracellular matrix (ECM), and immunohistochemical labelling and zymographic analysis to determine the le...
A study has been made of the kinetics of lysis induced by various hemolytic agents. The course of bemolysis was followed by mixing lysin with washed human erythrocytes, removing samples from the mixture, and estimating colorimetrically the hemoglobin in the supernatant fluid of the centrifuged samples. Most of the curves (but not all of them, e.g. tyrocidine) obtained by plotting degree of hemo...
