Current research concentrates on the impact properties of a particle reinforced polymer matrix composite material. The composite material consists of unsaturated polyester resin that is reinforced with aluminium hydroxide. Aluminium hydroxide acts as the hard phase and polyester as the binding agent. The aim of the work was to understand how the particle size and the filler material’s mass frac...

Purpose. To evaluate the efficacy and safety of polybutylate-coated braided polyester (Ethibond* 5-0) suture for levator aponeurosis suturing to the anterior tarsal surface in involutional blepharoptosis repair surgery. Methods. Ten consecutive patients (16 eyes) with acquired blepharoptosis which resulted from levator aponeurosis dehiscence with good levator function had gone through surgery a...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Composite materials are widely used because of their extreme properties. Researchers working on fabrication of new composite materials worldwide to enhance the applicability of these materials. There are very few works about the effect of nanoclay ...

A new compound composed of poly(ε-caprolactone) and β-cyclodextrin (β-CD) was synthesized by click chemistry. This compound was used to obtain stable nanoparticles, which have been proven to be able to complex phenolphthalein and adamantyl carboxylate. The nanoparticles are characterized by a distinct morphology, i.e., a hydrophobic core formed by the polyester chain and a shell containing the ...

Polyester pad was utilized as solid support for rearing Cochliomyia hominivorax Coquerel larvae in liquid diet and compared with the ground meat diet. There were no significant differences in the mean third instar larvae and pupal weights, number of pupae, emergence and rearing efficiency. The tests were conducted through four consecutive generations, presenting no detectable effect in any of t...

Stem/progenitor cells are promising candidates for a therapy of renal failure. However, sound knowledge about implantation and regeneration is lacking. Therefore, mechanisms leading from stem/progenitor cells into tubules are under research. Renal stem/progenitor cells were isolated from neonatal rabbit kidney and mounted between layers of polyester fleece. It creates an artificial interstitium...

Dielectric spectra of the polyester poly(propylene succinate) were measured upon crystallization. For this model aliphatic polyester the alpha and beta relaxations appear simultaneously and are well resolved in the experimental frequency window. During isothermal crystallization, this fact allows one to use the beta relaxation to characterize the crystalline structural development while the alp...

Compression properties of textile materials are useful for determining fullness, softness, smoothness, and stiffness. In addition, compression parameters have significant influence on fabric hand value quality materials. The present paper reports a study the sublimation printing process change in knitted fabrics (polyester, cotton, cotton/ polyester) intended sportswear manufacturing. For that ...

A series of monoazo disperse dyes based on naphthalimide was synthesized using N-alkylcarboxylic acid-1,8-naphthalimide as diazo component and N,N-diethylaniline derivatives as a coupling components. 4-amino-N-ethanoic (propanoic) acid-1,8-naphthalimide was synthesized from 4-nitro-1,8-naphthalic anhydride by imidation and subsequent reduction reactions. These compounds were diazotized and furt...
