Fixed and Mixed Effects Models in Meta-Analysis The last three decades the accumulation of quantitative research evidence has led to the development of systematic methods for combining information across samples of related studies. Although a few methods have been described for accumulating research evidence over time, meta-analysis is widely considered as the most appropriate statistical metho...

This article generalizes the tolerance interval approach for assessing agreement between two methods of continuous measurement for repeated measurement data — a common scenario in applications. The repeated measurements may be longitudinal or they may be replicates of the same underlying measurement. Our approach is to first model the data using a mixed model and then construct a relevant asymp...

It was shown previously that CsI sensitivity can be substantially reduced by intense UV irradiation. In the present study we measure the influence of negative and positive electric fields on the degradation of CsI photocathode sensitivity when it is subject to a large dose UV irradiation. The UV sensitivity of positively biased CsI photocathodes did not decay as fast as in case of negatively bi...

Low cost, highly efficient and safe devices for energy storage have long been desired in our society. Among these devices, electrochemical batteries with alkali metal anodes have attracted worldwide attention. However, the practical application of such systems is limited by dendrite formation and low cycling efficiency of alkali metals. Here we report a class of liquid anodes fabricated by diss...

astewaters from all processes w are collected by gravity flow into acid-alkali (rinses), chromate, cyanide, spenttstripping acids, and cleaner sumps. The acid concentrates and cleaner concentrates are gradually fed into chromate and acid-alkali (rinse) sumps, respectively. Cyanide destruction is achieved by oxidation with sodium hypochlorite whereas hexavalent chrome is reduced to trivalent chr...

We have observed depolarization effects when high intensity cold neutron beams are incident on alkali-metal spin-exchange-polarized 3He cells used as neutron spin filters. This was first observed as a reduction of the maximum attainable 3He polarization and was attributed to a decrease of alkali-metal polarization, which led us to directly measure alkali-metal polarization and spin relaxation o...

Alkali-activated binders (AABs) stand out as promising candidates to replace ordinary Portland cement (OPC) since waste can be used raw material for their manufacture. This study addresses the environmental feasibility of using weathered bottom ash (WBA) and metakaolin (MK) alkali-activated binder precursors (AA-WBA/MK). Different proportions WBA MK were mixed (100/0, 75/25, 50/50, 25/75, 0/100...
