In reliability or medical studies, we may only observe each ongoing renewal process for a certain period of time. When the underlying distribution F is arithmetic, Vardi (Ann. Statist. 10 (1982b), 772-785) developed the RT algorithm for nonparametric estimation. In this paper we extend the study to the nonarithmetic case and show that the choice of an arbitrary constant in the RT algorithm can ...

We consider the question of strong cosmic censorship in spatially compact, spatially locally homogeneous vacuum models. We show in particular that strong cosmic censorship holds in Bianchi IX vacuum space–times with spherical spatial topology.

A supersimple theory eliminates hyperimaginaries. In particular, in a supersimple theory Lascar strong type is the same as strong type, and every strong type has a canonical base in C . It follows that the Amalgamation Theorem (Independence Theorem) holds for types over algebraically closed sets.

Background and objectives: Melasma is one of the most common pigmentary disorders. It has a considerable impact on quality of life. The treatment of melasma has still remained a challenge because the efficient treatment has not been proven until now and there is still a need to find new depigmenting products.Allium cepa L. and Cucumis melo L. seeds as well as ...

BACKGROUND AND OBJECTIVES: Very low grid power penetration in some urban areas has led to telecoms companies investing massively in the deployment of diesel generators (DGs). These deployments have led to diesel and waste oil spill at base transceiver station (BTS) sites during maintenance cycles, impacting the environment and human activities. The objective of this study is to...

To the Editor: In his review on acid–base disorders, Seifter (Nov. 6 issue)1 attempts to integrate the “traditional, bicarbonate-centered model” described by Davenport2 and Boron3 with Stewart’s strong-ion-difference model4: strong ion difference (in mmol per liter) = [Na+] + [K+] + [Ca2+] + [Mg2+] – [Cl−]. In unbuffered salt solutions, strong ion difference = [OH−] – [H+] and is thus a pH surr...

OBJECTIVE To review the term hyperchloraemic acidosis. DATA SOURCES Articles and reviews from peer reviewed journals on acid-base physiology. SUMMARY OF REVIEW The concept of hyperchloraemic acidosis is well established in medicine and regularly taught to medical students. Unfortunately, it is yet another medical misnomer. Hyperchloraemic acidosis is only likely to exist with normal plasma ...
