One of the most relevant properties of composite materials to be considered is stiffness. Fiberglass has been used traditionally as a fibrous reinforcing element when stiff materials are required. However, natural fibers are been exploited as replacements for synthetic fibers to satisfy environmental concerns. Among the different natural fibers, wood fibers show the combination of relatively hi...

Methods are described for the efficient concentration of an enterovirus from large volumes of tap water, sewage, and seawater. Virus in acidified water (pH 3.5) in the presence of aluminum chloride was adsorbed to a 10-inch (ca. 25.4 cm) fiberglass depth cartridge and a 10-inch pleated epoxy-fiberglass filter in a series at flow rates of up to 37.8 liters (10 gallons) per min. Adsorbed viruses ...

The purpose of this study was to investigate the influence of gutta-percha solvents on the bond strength of fiberglass post to root canal dentin. Forty bovine incisors were decoronated, prepared, filled, and randomly distributed into four groups (n = 10) according to the gutta-percha solvent used: control, xylene, eucalyptol and orange oil. After root canal treatment, the posts were cemented in...

OBJECTIVE To quantify and compare the forces exerted by scoliosis patients in fiberglass braces during exercises usually prescribed in departments where casts are made. The exercises are intended to increase corrective forces, activate muscles, stimulate ventilation and help the patient psychologically. SETTING Outpatient care. PATIENTS 17 consecutive adolescent patients wearing fiberglass ...

Preparation of the shrimp breeding project began in 2018-2019. And creation suitable conditions for farming larvae white-legged shrimp, Penaeus vennami. The is funded by Iraqi Ministry Higher Education and Scientific Research. was designed specialists at Marine Science Centre (MSC). It aims to introduce P. vennami from neighboring Iranian farms transfer experiences after reviewing all its detai...

Caloapenesia Terayama is characterized by having the costal cell very long, the stigma of forewing absent, and the paramere deeply divided into two arms. Three species of this genus were known from Oriental Region. Sixteen new species from Indonesia, Thailand and Vietnam: C. ana sp. nov., C. arbeni sp. nov., C. diba sp. nov., C. edas sp. nov., C. heira sp. nov., C. inyara sp. nov., C. jailuna s...

A simple method of potentially wide applicability for obtaining synchronous cultures of Bacillus subtilis based on size selection is described. Using glass fiber filters, a population (about 1 to 2% of the parent population) can be obtained substantially enriched for small cells which grow synchronously. A method for rapidly concentrating dilute suspensions of cells is described.

The change in the absorption loss of IR-transmitting chalcogenide glass fibers in the temperature range of -90 degrees C or= 6 microm the change in loss was mainly due to multiphonon ...

We probe the local sensitivity of an optically excited plasmonic nanoparticle by changing the local dielectric environment through a scanning glass fiber tip. Recording the particle plasmon scattering spectrum for each tip position allows us to observe spectral resonance shifts concurrent with changes in scattering intensity and plasmon damping. For the tip-induced spectral shifts we find the s...
