Anaerobic digestion of manure is a widely accepted technology for energy production. However, only a minimal portion of the manure production in the EU is anaerobically digested and occurs predominantly in codigestion plants. There is substantial potential for biogas plants that primarily operate on manure (>90%); however, the methane yields of manure are less compared to coproducts, which is o...

Background and Aim: There is lack of information regarding the effect of different denture cleansing solutions on the retention of attachments. This study aimed to as-sess the effect of denture cleansing solutions on the retention of Dalbo-Plus and Loca-tor attachment systems. Materials and Methods: This study evaluated 160 attachments including 80 Locator and 80 Dalbo-Plus attachment systems....

Previous research has shown that repeated retrieval with written tests produces superior long-term retention compared to repeated study. However, the degree to which this increased retention transfers to clinical application has not been investigated. In addition, increased retention obtained through written testing has not been compared to other forms of testing, such as simulation testing wit...

Post traumatic stress disorder (PTSD) is a debilitating anxiety disorder resulting from traumatic stress exposure. Females are more likely to develop PTSD than males, but neurobiological mechanisms underlying female susceptibility are lacking. This can be addressed by using nonhuman animal models. Single prolonged stress (SPS), a nonhuman animal model of PTSD, results in cued fear extinction re...

The determination of the relative value of files is important for an organization while determining a retrieval service level for its files and a corresponding file retention policy. This paper discusses via a literature review methods for developing file retention policies based on the use values of files. On basis of these results we propose an enhanced version of one of them. In a case study...

We used 15N-labelled nitrate (NO−3 ) additions to investigate pathways of nitrogen (N) cycling at the wholereach scale in three stream reaches with adjacent forested, urban and agricultural land areas. Our aim was to explore among-stream differences in: (i) the magnitude and relative importance of NO−3 retention (i.e. assimilatory uptake) and removal (i.e. denitrification), (ii) the relative co...

introduction: water and soil retention curve is one of the most important properties of porous media to obtain in a laboratory retention curve and time associated with errors. for this reason, researchers have proposed techniques that help them to more easily acquired characteristic curve. one of these methods is the use of fractal geometry. determining the relationship between particle size di...

customer activity has received more attention due to the increase of social network applications. moreover, customer activity could be an answer to the research debate about the significant relationship between retention rate and lifetime profitability of customers. several researchers believe that an increase in the retention rate of customers may enhance their customer lifetime value (clv), o...

Eighteen aminoglycosidic antibiotics and their degradation products, containing 2-deoxystreptamine as a commonmoiety, were separated by gas-liquid chromatography. The largest compounds examined included the pentacyclic lividomycins A and B. These compoundswere separable from each other either as pertrimethylsilyl derivatives or N-trifluoroacetyl pertrimethylsilyl derivatives on a single column ...

Natural geological conditions together with the impact of human activities could produce environmental problems due to high As concentrations. The aim of this study was to assess the role of epipsammic biofilm-sediment systems onto As (V) sorption and to evaluate the effect of the presence of equimolar P concentrations on As retention. A natural biofilm was grown on sediment samples in the labo...
