Precise Point Positioning (PPP) is a popular technology for precise applications based on the Global Navigation Satellite System (GNSS). Multi-GNSS combined PPP has become a hot topic in recent years with the development of multiple GNSSs. Meanwhile, with the operation of the real-time service (RTS) of the International GNSS Service (IGS) agency that provides satellite orbit and clock correctio...

This document defines extensions to the Layer Two Tunneling Protocol (L2TP) for enhanced support of link-specific Point to Point Protocol (PPP) options. PPP endpoints typically have direct access to the common physical media connecting them and thus have detailed knowledge about the media that is in use. When the L2TP is used, the two PPP peers are no longer directly connected over the same phy...

Positive relationships between heterotrophic bacteria and particulate phytoplankton production (respectively, BP and PPP) have been reported for several areas, suggesting that material produced by phytoplankton was a major substrate for bacterial growth. Since then, thousands of simultaneous measurements of both PPP and BP have been performed. A review of these data showed that BP may exceed PP...

OBJECTIVE Platelet-rich plasma (PRP) can promote wound healing. To observe the effect of PRP injection on the early healing of rat's Achilles tendon rupture so as to provide the experimental basis for clinical practice. METHODS Forty-six Sprague Dawley rats were included in this experiment, female or male and weighing 190-240 g. PRP and platelet-poor plasma (PPP) were prepared from the heart ...

The workshop entitled "Public-Private partnerships models in Europe-- comparison between France and European countries" brought together representatives of academia and industry, of national or European health research programs, of regional or national public-private partnership (PPP) initiatives, and of biotechnology with the following objectives: sharing a common vision on the needs, expectat...

Glioblastoma (GB) is the most common malignant brain tumor in adults. It has limited treatment opportunities and is almost exclusively fatal. Owing to the central role the insulin-like growth factor-1 receptor (IGF-1R) plays in malignant cells, it has been suggested as a target for anticancer therapy including GB. The cyclolignan picropodophyllin (PPP) inhibits IGF-1R without affecting the high...

This article provides a framework to guide the choice and design of a fitting Public Private Partnerships (PPP), which is applied to a Dutch example of biogas/sustainable energy projects. The framework focuses on ‘legitimate public governance’, merging Beetham’s dimensions of legitimacy (legality, shared beliefs and consent) with three types of governance mechanisms (market, network and hierarc...

Recent studies of purchasing power parity (PPP) account for the possible presence of unit roots in nominal exchange rates and relative price indices by applying standard unit-root tests to real exchange rates, which are ratios of nominal exchange rates and relative price indices. These studies occasionally find evidence of PPP, but as a whole, the evidence is not definitive. Standard unit-root ...

In recent years, there has been a revival of interest in metabolic changes of cancer cells as it has been noticed that malignant transformation and metabolic reprogramming are closely intertwined. The pentose phosphate pathway (PPP) is one of the fundamental components of cellular metabolism crucial for cancer cells. This review will discuss recent findings regarding the involvement of PPP enzy...

INTRODUCTION Palmoplantar pustulosis (PPP) is a chronic pustular inflammatory skin disease; however, its pathogenesis is not well understood. Several factors, such as genetics, tobacco use and autoimmune issues, may contribute to this disease. AIM This research was conducted to investigate the relationships between insulin resistance, thyroid disease and PPP. MATERIAL AND METHODS Thirty-thr...
