A method for preparing and characterizing microencapsulated phase change materials (MPCM) was developed. A comparison with a commercial MPCM is also presented. Both MPCM contained paraffin wax as PCM with acrylic shell. The melting temperature of the PCM was around 21 °C, suitable for building applications. The M-2 (our laboratory made sample) and Micronal® DS 5008 X (BASF) samples were charact...

Solenopsis geminata group (Hymenoptera: Formicidae) encompasses ant species commonly called fire ants because of their painful sting. The many physiological effects of the venom are caused by 2-methyl-6-alkyl and/or alkenylpiperidine alkaloids. The variation in piperidine alkaloid structures has useful taxonomic characters. The most well studied Solenopsis species is Solenopsis invicta, which w...

Busulfan disposition is age-dependent with a higher clearance and a larger volume of distribution in children than in adults. The optimal dosage of busulfan needed to achieve bone marrow (BM) displacement in young children with malignant or nonmalignant disease remains to be defined. Using a gas chromatography-mass spectrometry assay, we evaluated plasma pharmacokinetics of busulfan in 33 child...

9. Accumulation of glutamate also occurred in isolated kidney cortex, spleen, lung and chorion. Six other tissues examined maintained a concentration gradient between tissue and medium, but did not increase the glutamate concentration above the original level. 10. It is pointed out that tissue slices afford a system in which problems of permeability and storage can be studied under controlled c...

introduction: this study carried out to investigate the causes and motivations of older people residing in nursing home. methods: a qualitative description study was designed by choosing a sample of the elderly residing in a nursing home in tabriz, iran. based on purposive sampling, fifteen residents in the age range of 65-85 participated in the study. data was collected through unstructured in...

in this paper, the interface crack of two non-homogenous functionally graded materials is studied. subsequently, with employing the displacement method for fracture of mixed-mode stress intensity factors, the continuous variation of material properties are calculated. in this investigation, the displacements are derived with employing of the functional graded material programming and analysis o...

Vertical velocity characteristics of the optically clear convective boundary layer (CBL) are examined by means of profiling airborne radar data collected in the central Great Plains during the International H2O Project, May–June 2002 (IHOP 2002). Clear-air echoes are sufficiently strong for the radar, a 95-GHz cloud radar, to detect most of the CBL at a resolution of 30 m. Vertical radar transe...

It has been shown (Fraenkel-Conrat, 1950) that the enzymic activity of lysozyme depends upon the presence of some of its amino, carboxyl and hydroxyl groups. A study of the structure of the lysozyme molecule as awhole has been undertaken in an approach to the problem of defining that portion of the molecule which is concerned in its activity. The lysozyme molecule probably consists of a single ...

background: centre of pressure displacement is an indicator of postural control. children with cerebral palsy have poor postural control. one common intervention to enhance their balance is vestibular stimulation. the aim of this research was to investigate the effect of vestibular stimulation on cop parameters in children with cerebral palsy (3-10 years old). methods: this study was a randomiz...

Gram-negative pathogens commonly use the chaperone-usher pathway to assemble adhesive multisubunit fibers on their surface. In the periplasm, subunits are stabilized by a chaperone that donates a beta strand to complement the subunits' truncated immunoglobulin-like fold. Pilus assembly proceeds through a "donor-strand exchange" (DSE) mechanism whereby this complementary beta strand is replaced ...
