Abstract:

This essay tries to explain in general terms Minkowski's notion of temporal retention. The title “ghosts retreating” expresses exactly the flow of the succinct and ephemeral temporal states of retention. The methodology is critical-reflective. We conclude that lived time for Minkowski, only becomes alive through the power of retention.

Abstract:

The coffee flavor compounds acquire a significant place in the improving the flavor of cigarette. In the present paper, the support vector machine is used to develop quantitative relationships between the retention time and four molecular descriptors of 52 compounds. The model of support vector machine gives good statistical results compared to those give by multiple linear regressions and support vector machine. The contribution of each descriptor to structure-retention time relationships was evaluated. It indicates the importance of the atoms number and type of parameter. The proposed method

Abstract:

Because people forget much of what they learn, students could benefit from learning strategies that yield long-lasting knowledge. Yet surprisingly little is known about how long-term retention is most efficiently achieved. Here we examine how retention is affected by two variables: the duration of a study session and the temporal distribution of study time across multiple sessions. Our results suggest that a single session devoted to the study of some material should continue long enough to ensure that mastery is achieved but that immediate further study of the same material is an inefficient

Diets contained four conifers and either 0, 5, 15, or 25 % of a fruticose lichen component. Digesta retenton time was calculated using forages that were marked with ytterbium. Feces were collected up to 168 h postdosing, and subsamples were analyzed for ytterbium by atomic absorption spectrophotometry. Across all tria

Retention tanks (RTs) are commonly used to reduce combined sewer overflows, management of which is an important way of reducing the impacts of urban development on receiving waters. However, overflow characteristics and the processes affecting them are not yet fully understood. In a context of integrated urban wastewater systems, the management of RTs is mainly done to satisfy hydraulic constraints even if the idea behind such structures is to limit the discharge of pollutants to the environment.

Retention time prediction, facilitated by advances in machine learning, has become a useful tool in untargeted LC-MS applications.

These approaches demonstrate accurate predictions comparable with the experimental error for the training set. The weak point of retention time prediction approaches is the transfer of predictions to various systems. The accuracy of this step depends both on the method of mapping and on the accur

Abstract:

In gas chromatography–mass spectrometry-based untargeted metabolomics, metabolites are identified by comparing mass spectra and chromatographic retention time with reference databases or standard materials. In that sense, machine learning has been used to predict the retention time of metabolites lacking reference data. However, the retention time prediction of trimethylsilyl derivatives of metabolites, typically analyzed in untargeted metabolomics using gas chromatography, has been poorly explored.

Abstract:

Steroidomics studies face the challenge of separating analytical compounds with very similar structures (i.e., isomers). Liquid chromatography (LC) is commonly used to this end, but the shared core structure of this family of compounds compromises effective separations among the numerous chemical analytes with comparable physico-chemical properties. Careful tuning of the mobile phase gradient and an appropriate choice of the stationary phase can be used to overcome this problem, in turn modifying the retention times in different ways for each compound. In the usual workflow, this approach is s

Abstract:

Reservoirs are an important nitrogen sink as a result of their retention effect, but their retention performance may vary with hydrologic conditions with time-varying characteristics, which also change them from being a sink to source over time. This study uses a coupled modelling system (Soil and Water Assessment Tool (SWAT) and a two-dimensional hydrodynamic and water quality model (CE-QUAL-W2) to analyze the nitrogen retention effect and influential factors at annual, monthly, and daily scales in Shanmei Reservoir in southeast China. The results showed that there was a positive retention ef

Abstract:

This research analyzes the retention time of the three phase separator in separating oil, water, and gas phases at PT Pertamina refinery unit IV Cilacap. With an initial retention time ranging from 31 - 34 minutes, there are phases that are still not separated in the separator. This study aims to provide recommendations for retention time based on unseparated phases and how to apply them to the separator at the refinery. This study involves three types of lube oil analyzed, namely DAO, MMO, and LMO. The results show that there is still a difference between the phases at the inlet and outlet wh

Abstract:

Correlative microscopy was applied to study the influence of solids retention time on activated sludge floc structure. Conventional optical microscopy revealed flocs at lower SRTs (4 and 9 days) to be irregular in shape while flocs at higher SRTs (16 and 20 days) had a more spherical and compact structure. Flocs were examined by environmental scanning electron microscopy (ESEM) and by transmission electron microscopy (TEM) coupled with energy-dispersive spectroscopy (EDS). Distinctive differences in floc structure and the arrangement of EPS were revealed. Flocs from higher SRTs were less hydra

Abstract:

The present study tested the hypothesis that the international undergraduates at a West Coast American public university during recent years of dramatic enrollment growth should have low retention and graduation rates. This study showed instead that these students were retained and graduated at rates surpassing predictions from research and theories on international undergraduates’ unique challenges (American immigration regulations, academic integrity standards, and teaching methods; English writing) and academic struggles. Moreover, contrary to predictions related to academic struggles, the

The findings show there is significant relationship between mental accounting and power-prestige toward consumptive behavior. Meanwhile, retention-time does not affect significantly toward the behavior.
