In peritoneal dialysis (PD) the dialysate is introduced into the peritoneal cavity, and the peritoneal membrane is used as the dialysis membrane. In PD, patients exchange the dialysate by themselves through the connection tube attached to the indwelling catheter that is inserted into the peritoneal cavity. Microbes may enter the peritoneal cavity during dialysate exchange, and, therefore, perit...

Let G be a connected, unipotent, perfect group scheme over an algebraically closed field of characteristic p > 0 and let E be a biextension (cf. [SGA7tI], exp. VII, no. 1) of G ×k G by the discrete group Qp/Zp. When E is skewsymmetric (cf. sec. 3.1), V. Drinfeld defined in [Dr] a certain metric group A (cf. appendix) associated to E. In this article, we prove a conjecture stated in [Dr] (cf. se...

Seit dem Jahr 2004 ermöglichen die Forschungsdatenzentren der Statistischen Ämter des Bundes und der Länder die Umsetzung eines gesetzlich eröffneten Privilegs für die Wissenschaft: den Zugang zu Mikrodaten der amtlichen Statistik für Forschungsvorhaben. Dieser Datennutzungsweg ist mittlerweile gut etabliert und insbesondere in der empirischen Agrarstrukturforschung weit verbreitet. Zum Beispie...

the arabic grammarians call the “main preposition + genitive noun” and an “adverb” a “prepositional phrase”. for prepositional phrases to assimilate into the sentence structure and fulfill their roles, they should have a specific connection and link to another part of the sentence. this link is called “attachment” and that part is named “attached phrase”. consequently, a prepositional phrase ca...

Network Attached Storage (NAS) has been gaining general acceptance, because it can be managed easily and files shared among many clients, which run different operating systems. The advent of Gigabit Ethernet and high speed transport protocols further facilitates the wide adoption of NAS. A distinct feature of NAS is that NAS involves both network I/O and file I/O. This paper analyzes the layere...

I nteractions with extracellular matrix proteins such as fi bronectin infl uence cell locomotion, survival, and even growth. At the crux of all these activities sit integrins, transmembrane receptors that pass environmental information into the cell and also modulate the cell's interactions with the exterior milieu. Appreciation and understanding of integrins' importance continues to grow, but ...

The Spallation Neutron Source (SNS) diagnostic instruments at Oak Ridge National Laboratory are based on the Network Attached Device (NAD) concept. Each pickup or sensor has its own resources, such as networking, timing, data acquisition, and processing. NADs function independently thus reducing the brittleness inherent in tightly coupled systems. This paper describes our implementation of the ...

The D-DART (Droplet and Aerosol Reducing Tent) is a foldable design that can be attached to the dental chair prevent spread of contaminated aerosols. objective this study was evaluate ability reduce aerosols generated during treatment. Thirty-two patients (sixteen per group) undergoing deep ultrasonic scaling were recruited randomly allocated groups or Control (no D-DART). After 20 min from sta...
