China has had a rapid increase in its economy over the past three decades. However, the economic boom came at a certain cost of depleting air quality. In the study, we aimed to examine the burden of air pollution and its association with climatic factors and health outcomes using data from Chinese national and city-level air quality and public health surveillance systems. City-level daily air p...

Contactless atmospheric pressure ionization (C-API) method has been recently developed for mass spectrometric analysis. A tapered capillary is used as both the sampling tube and spray emitter in C-API. No electric contact is required on the capillary tip during C-API mass spectrometric analysis. The simple design of the ionization method enables the automation of the C-API sampling system. In t...

Wrapping is an established technique for API migration: the use of a given API within the system under migration is replaced by the use of a wrapper-based re-implementation of said API while using a different (preferred) API underneath. Except for some special cases, wrapper development is a craft. In particular, the compliance of a wrapper with the original API is hard to assess and guidance o...

To provide a basis for controlling the quality of rhubarb under artificial cultivation, the present work was designed to evaluate the contents of 14 active pharmaceutical ingredients (API) of rhubarb in major rhubarb production areas in China and analyze the correlations between the contents of API and such factors as species, geographic distribution and soil. The levels of fourteen API in rhub...

Abstract This work describes a rhynchonellid and spire-bearing brachiopod fauna from the Ixtaltepec Formation of Oaxaca, Mexico. Leiorhynchoidea perrilliatae , Allorhynchus scientiana Anthracospirifer oaxacaensis are new species. The specific determination, along with information previously described taxa, allowed establishment precise relative ages different fossiliferous intervals (API-1 to A...
