A method for the production of paper with high strength and grease resistance was developed. Filter paper was impregnated by an aqueous solution of zinc chloride at a fixed temperature for several seconds. Swelling and partial dissolution of the cellulose fibers resulted in strong and compact paper. Various influencing factors were investigated in an attempt to improve the grease resistance of ...

The basement membrane components in the primary and metastatic lesions of 29 cases of early gastric cancer were histologically and immunohistochemically examined. On silver-impregnated specimens, reticular fibers were much more abundant in the basement membrane regions and stromal tissues in the metastatic lesions than in the primary lesions. Immunohistochemically, the basement membrane compone...

Teeth that have short clinical crown, which are not alone enough to support the definitive restoration can be best treated using the post and core system. The advantages of fiber post over conventional metallic post materials have led to its wide acceptance. In addition to that the combination of aesthetic and mechanical benefits of fiber post has provided it with a rise in the field of dentist...

In the present study, fabrication and characterization of compound composite nanofibers of Polyvinyl Alcohol (PVA) with nano silver and Polyamide 6 (PA6) are demonstrated. Compound composite fibers with core-shell structure were made using co-axial electrospinning method. The shell was made up of nano silver (Ag) impregnated PVA while PA6 was the core material. These compound composite nanofibe...

Fibers represent a type of structure great interest in catalysis since they combine high area to volume ratio and can be fabricated from many types materials, such as ceramic oxides, polymers, alloys. They used isolated form or structured, the case papers synthesized this work, following modified papermaking technique. The addition cationic anionic polyelectrolytes improved retention fibers dur...

In this study; experimental failure analysis was investigated on adhesively single-lap joints produced using adhesives reinforced with uni-directional glass fibers. Epoxy adhesive impregnated fiber were used to join composite plates joints. It is aimed strengthen the joint by layers between two plates. The loads of obtained compared attached non-reinforced adhesive. Also, 0o, 15o 30o and 45o re...

This paper describes a study of the quantify surface roughness of experimentally manufactured particleboards and sandwiched panels having fibers on the surface layers. Surface quality of specimens before and after being overlaid with thin melamine impregnated papers was determined by employing profilometer equipment. Roughness measurements and Janka hardness were carried out on the specimens co...

Microanatomical studies on the abdominal stretch receptor organs of the crayfish Astacus fluviatilis L. have been carried out in order to establish a basis for the physiological work that has been, and is being carried out on stretch receptors of various species of crayfish. Important differences have been found between these organs and those previously described by Alexandrowicz for the lobste...
