BACKGROUND/AIM Isolated stenosis of the lacrimal punctum is a frequent cause of epiphora. Treatment relies on surgical opening or dilatation with bi- or monocanalicular prosthesis. Recently, silicone perforated punctum plugs (PPP) were proposed. The drawback with these silicone PPP was that secretions accumulate in the central orifice blocking the spontaneous flow of tears. A modification of th...

Currently, the precise point positioning (PPP) technique is a well-established GNSS processing method for postprocessing applications, while real-time PPP is still a field of ongoing research. Meanwhile a new RTCM (Radio Technical Commission for Maritime Services) standard for exchanging PPP corrections has been released. This so-called state space representation (SSR) contains orbit and clock ...

patients and methods we conducted an observational prospective study in adults proposed to various types of surgery using the brief pain inventory short form preoperatively (t0), one day after surgery, and three months later (t3). if the patient had pain at t3 and other causes of pain were excluded, they were considered to have ppp, and the mcgill pain questionnaire short form was applied. qol ...

the mechanism of public-private partnership (ppp) has been used in different countries. many countries have enacted special laws to regulate ppps. in iran, ppp as such has been briefly mentioned in the fifth five year development act and more details of ppps were provided in the yearly budget acts of 1391 and 1392 (2012 and 2013). in the budget act of 1393 (2014) the detailed provisions regardi...

background and objectives: public-private partnership (ppp) is a well-established model to alleviate the risk of investment in health domain. while the model is widely applied in the developed countries, the adoption of the model in many developing countries is hampered partly by the lack of knowledge on dimensions and requirements of its local implementation. the present study, thus, aimed to ...

Pustulosis palmaris et plantaris (PPP) is a chronic relapsing skin disease characterized by sterile intraepidermal pustules and, usually, by scaly erythematous skin on the palm, soles, or both. To determine the primary pathogenic factors involved in the onset of PPP, we analyzed the implications of heat shock proteins (HSPs), which are highly conserved immunogenic proteins, chronic microbial in...

Examining the interrelationships among critical success factors (CSFs) for public private partnership (PPP) projects is of importance for improving PPP project performance and maintaining the sustainability of PPP project implementation. Previous studies mostly focused on the identification of the CSFs for PPP projects; limited studies investigated the interrelationships among CSFs. Hence, the ...
