Abstract Microorganisms are considered one of the most dangerous deterioration factors to cellulosic textiles, especially textiles made linen fibers. Many traditional methods resistance microorganisms that infect were used in past, but they low effectiveness and high toxicity for those who applied these methods. The study silver nanoparticles (AgNPs) prepared by chemical reduction nitrate (AgNO...

TGA measures the amount and rate (velocity) of change in the mass of a sample as a function of temperature or time in a controlled atmosphere. The measurements are used primarily to determine the thermal and/or oxidative stabilities of materials as well as their compositional properties. The technique can analyze materials that exhibit either mass loss or gain due to decomposition, oxidation or...

asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...

Hydrogel templates are formed to entrap various pre-polymers prior to their crosslinking process. Upon the completion of the crosslinking process, an independent polymer network with the same fiber geometry is formed. The hydrogel template can be removed if necessary. As the proof-of-principle, fibers from various polymers are fabricated. The fabricated hybrid polymeric fibers are bioactive and...

The cyclical changes in the gonadotropins stimulate ovarian follicular development either to the ovulatory stage or to undergo atresia. One such intrafollicular factor may be inter-cellular communication via gap junctions. We have examined the effects of two agents (retinoids and alkanols), known to disrupt or uncouple gap junction, on FSH-stimulated LH receptor induction and progestrone synthe...

Recycled fibers are essential raw materials used by the paper industry. However, strength of formed may fall off excessively after several cycles reuse fibers. Herein, authors measured changes in physical properties and fiber size multiple recycling prepared a handsheet from recycled different times. Then handsheets made with that had been 5 times were double-coated nanocellulose derivatives to...

The C-terminus of alpha-tubulin undergoes a reversible posttranslational tyrosination/detyrosination. The distributions of the tyrosinated (Tyr) and nontyrosinated (Glu) species during mitosis of cultured cells have been investigated by immunofluorescence using antibodies directed against the C-terminus of either Tyr or Glu tubulin. The distribution of Tyr tubulin differed from that of Glu tubu...
