OBJECTIVES To describe and evaluate disposable saliva collection kit for rapid, reliable, and reproducible collection of saliva samples. METHODS The saliva collection kit comprised of a saliva absorbent swab and an extractor unit was used to retrieve whole saliva samples from 10 subjects. The accuracy and precision of the extracted volumes (3, 10, and 30 μl) were compared to similar volumes d...
Background & Aim: A herbarium is a collection of preserved plant specimens. Herbarium specimens form an important recorded of what plants grew where over time. Kerman province with area about 171993 km2 has a lat of difference vegetation because of climatic and topography variations. It has different elevation (above sea level) from 300 m in Shahdad to 4420 m in Hezar mountains. Mat...
Trace driven simulation is an important tool for computer systems performance analysis and prediction, but its accuracy decreases when incomplete or inaccurate traces are used for input. Nevertheless, many memory hierarchy simulation studies have been published which rely on such traces. In this paper we describe BACH, a hardware monitor developed to capture long, accurate, and complete traces ...
Discovering resource descriptions and merging results obtained from remote search engines are two key issues in distributed information retrieval studies. In uncooperative environments, query-based sampling and normalizing scores based merging strategies are well-known approaches to solve such problems. However, such approaches only consider the content of the remote database and do not conside...
No current garbage collector combines space efficiency, low collector times, and mutator (application) locality for contemporaneously allocated objects. For example, free-list allocation coupled with mark-sweep collection achieves space efficiency, but poor mutator locality. On the other hand, contiguous (bump-pointer) allocation with copying collection provides mutator locality but poor space ...
The managers of the valuable resources held by museums, archives and libraries compile descriptions of their holdings both so that they can administer and control those resources more effectively and in order to enhance access to those resources by disclosing information about their existence and availability to potential users. The channels through which resource managers provide that informat...
