We read with interest the paper by Lee et al. [1]. They reported that continuous exposure to an electromagnetic field with extremely low frequency may induce testicular germ cell apoptosis in mice. Our group performed a series of experiments on the effect of exposure to an electrostatic field on spermatogenesis and sexual activity [2–7]. Polyester (polyethylene terphthalate) exhibited electrost...

Intestinal alkaline phosphatase is one of the major sources of alkaline phosphatase in circulation. It is secreted into the intestinal lumen, serum, and lymph. Following the ingestion of lipid, lymphatic alkaline phosphatase secretion increases significantly. We have found that the non-absorbable fat, olestra, is unable to stimulate lymphatic alkaline phosphatase secretion. We also found that t...

Fabric has the power to humanize our living environment. Textiles have always had an ability to demarcate space, absorb sound and create decorative elements. With these characteristics, it is not difficult to explore the full potential of heat setting on polyester as a decorative surface design technique. Utilizing the heat setting properties of polyester, a range of fabrics has been designed a...

The disinfection of surfaces in the immediate surrounding of a hospitalised patient is considered to be an important element for prevention of nosocomial infection. The type of fabric in a mop, however, has to our knowledge never been regarded as relevant for an effective disinfection of surfaces. We have therefore studied the adsorption of benzalkonium chloride (BAC), glutardialdehyde and prop...

Traditionally polyester production is done in a batch reactor equipped with a separation column for batch distillation. A promising alternative for the intensification of this process is reactive distillation. In this paper, a reactive distillation model is developed for the synthesis of an unsaturated polyester process. The simulation results are compared with the industrial batch reactor outp...

The adsorption of polyester onto organically modified silicas (ormosils) and (commercial) fumed silica has been compared utilising ToF-SIMS. The thermodynamics of each system was examined by constructing adsorption isotherm plots which indicated that the adsorption of polyester onto one of the modified silicas used may be a two stage process. Adsorption onto the fumed silica is in accord with t...

Mechanical behaviour of unsaturated polyester resin used for the composite materials has been studied to determine various important parameters, such as tensile and compressive, single edge-notch tensile fracture toughness, flexural properties and fracture energy. Fracture toughness, KIC, and fracture energy, GIC, obtained for the polyester resin lie between the typical values for epoxy resins ...

The influence of different experimental conditions on the thermal comfort behavior of polyester-viscose and polyester-cotton ring and MJS yarn fabrics has been studied. The results show that the yarn structure and the fibre cross-sectional shape have a large influence on improving the thermal comfort of woven fabrics. The fabrics made from MJS yarns perform better than those of the ring yarn fa...

A new process for the manufacture of microfluidic devices based on deposition of laser-printing toner on glass substrates is described. It is an alternative method to the toner on polyester film (toner-polyester) one, previously introduced. Commercial laser printers cannot print directly on glass, thus the toner must first be printed on a special paper and then transferred by heating under pres...
