OBJECTIVES Seminal plasma elicits recruitment of immune cells into the cervix. It increases in mice in vivo and in humans in vitro the endometrial epithelial expression of those cytokines and growth factors, which play an essential role in implantation. To analyse if the stimulatory effect of seminal plasma correlates to the quality of the sperm count, the(More)
A pilot plant has been operated in order to investigate the performance and operating characteristics of the plant concept developed for the extension of the main Vienna STP. Due to the different operational modes included in the plant concept, modelling of the carbon degradation becomes of crucial importance. A new activated sludge model is introduced(More)
An Austrian research project focused on the development of process indicators for treatment plants with different process and operation modes. The whole treatment scheme was subdivided into four processes, i.e. mechanical pretreatment (Process 1), mechanical-biological waste water treatment (Process 2), sludge thickening and stabilisation (Process 3) and(More)
"Disposal or reuse?" is the big question in respect to sewage and water sludges. This question is even more decisive for small plants, because the achievement of the advanced treatment necessary for disposal is much more difficult in small units than in big ones. The paper discusses this question with main focus on small WWTPs and gives a short overview of(More)
Overcapacities of anaerobic digesters at municipal WWTPs are frequently used for the treatment of organic wastes in order to increase the biogas production. However, "co-digestion" of organic wastes leads to additional nitrogen loading and to additional loads of non-biodegradable COD. The effects of (co-) digestion of organic wastes from agro-industries(More)
PURPOSE To assess the metformin effect on endometrial stromal cell decidualization, proliferation, gene and protein expression of IGFBPs, IGFs and their receptors. METHODS Human endometrial stromal cells (hESCs) were cultured from endometrial biopsies of 11 women undergoing surgery for benign reasons. hESCs were decidualized with and without metformin in(More)
