PURPOSE Human lenses are generally obtained from eye bank eyes, which have been stored in the cold for extended periods. It is not known what effect the storage has on the lens. In this study, we examine the effects of post mortem time on the weights of sheep lenses left in the eye. METHODS Lenses were removed from 299 ex vivo sheep eyes (200-day-old), which had been kept on ice for various t...

Seeds are important materials for the restoration of globally-threatened marine angiosperm (seagrass) populations. In this study, we investigated the differences between different Ruppia sinensis seed types and developed two feasible long-term R. sinensis seed storage methods. The ability of R. sinensis seeds to tolerate the short-term desiccation and extreme cold had been investigated. The tol...

The chemical forms of phosphorus (P) in sediments are routinely measured in studies of P in modern and ancient marine environments. However, samples for such analyses are often exposed to atmospheric oxygen during storage and handling. Recent work suggests that long-term exposure of pyrite-bearing sediments can lead to a decline in apatite P and an increase in ferric Fe-bound P. Here, we report...

Wet-etching is a key step in wafer fabrication. A wet-etch station is a chemical batch process involving a complex interplay of mixed intermediate storage (MIS) policies and a shared robot for wafer transfers. Its operation poses a challenging resource-constrained scheduling problem that is crucial for enhancing productivity, improving yield and minimizing contamination. In this paper, we devel...

The study was to evaluate the marginal leakage of wet or dry dentin condition after restoration on short-term. In the study we used Photobond adhesive system and Single Bond adhesive system. The specimens were prepared from premolars. A class V cavity was prepared at the CEJ with a high-speed hand piece and #010 round diamond point. The cavity's walls and floors were etched with phosphoric acid...

Introduction: Optimization of waste collection systems can reduce waste management costs. In this study, optimization of the waste collection system of district 3 of Yazd municipality of Iran has been investigated using underground containers. Materials and Methods: In this research, after collecting information and performing field inspections, the statistical and raster information obtained ...

Numerous post-ophiolite intrusions exposed into the late Cretaceous–Paleocene Sabzevar ophiolite belt, northeast Iran. The intrusions consist of calc-alkaline intermediate to felsic rocks with metaluminous to peraluminous in nature and adakitic affinities. Based on U-Th-Pb dating on separated zircons by SHRIMP Ⅱ, the emplacement age of these rocks into the ophiolite zone is constrained to ~45 M...

Anisotropic nanostructures of metals are extensively studied due to their sizeand shapedependent properties and interesting growth mechanisms. Usually materials based on noble metals are investigated in this context, although anisotropic nanostructures of other transition metals are also prepared. Spherical as well as anisotropic magnetic nanoparticles are of great interest due to potential app...

In this chapter, we describe a few popular experimental methodologies that can be used to independently validate the results of a microarray experiment. In contrast to many of the other chapters in this book, the techniques described here are decidedly non-mathematical or statistical in nature. Instead, most of them utilize standard 'wet-bench' molecular biology protocols that have proven thems...

A life cycle assessment of the impact of distillers grains plus solubles (DGS) on mitigation of energy and greenhouse gas (GHG) emissions comparing corn ethanol to gasoline demonstrates the importance of feeding wet DGS (WDGS) to feedlot cattle to optimize the environmental benefit of ethanol production relative to gasoline. Ethanol produced in Nebraska has a superior environmental impact compa...
