Prediction and quantification of bioclogging depth limit and rate based on numerical simulation and experimental validation in managed aquifer recharge

Many microorganisms are naturally occurring in both recharging water and porous media, and microorganisms will grow and clog the pores of porous media. Porous media show different clogging depth and rate, which depends on the carbon source concentration. The bioclogging depth limit and rate under the effect of the nutrient concentration can be disentangled through column experiments and numerical simulation approaches. We use the TOUGHREACT method‐based on the monod equation of microbial growth to explore the process of microbial growth and permeability change, and correct with experimental results. The experimental results show the influence of nutrient concentration (glucose) on microbial growth and clogging of porous medium, and leads to clogging of porous medium. The clogging rate was defined as the rate of change of hydraulic conductivity with time for quantitative study of bioclogging in our study. Simulated results found that the clogging rate increases 0.035 and 0.00673 (m/d/min) respectively in the glucose concentration range of 0.045–0.6 and 0.6–5 mmol/L, simultaneously, the ultimate clogging depth decreases 18.2 and 1.7 mm respectively in the glucose concentration range of 0.045–0.6 and 0.6–5 mmol/L. The aim of this study was to evaluate the effects of nutrient concentrations on bioclogging and shed light on the establishment of nutrient concentration standards for recharge water during groundwater artificial recharge.
HR PRACTICES AND PERFORMANCE AMONG TEACHERS IN PAKISTAN

The purpose of this qualitative study is to explore the perceptions and understanding of teachers about ‘HRM practices both in public and private universities of Pakistan. Further, to explore how teachers associate the fairness of HR practices and other organizational factors, to the individual and organizational outcomes/performance. To this end, semi structured interviews were conducted to explore the perceptions of teachers about HR practices and performance. The findings of the interviews indicate that the existence of fairness of HR practices not only makes teachers work better (Teacher’s performance) but also generate a feeling of obligation to contribute towards organizational objectives (Exchange relationship). It is also evident from the interviewees’ account that among other organizational factors, organizational support is also one of the most critical factors which develops a feeling of commitment and satisfaction with the organization. However, in this context, the role of HR managers is very important not only in developing such HR systems that give employees a sense of organizational support but to implement those systems, practically giving them the signal of organizational justice. This study is unique as it is an attempt to integrate the perspective of teachers in HRM and performance literature which is a highly under-researched group in developing countries like Pakistan. This study can also help HR practitioners and educational policy makers in designing holistic and employee friendly policies if they want to be competitive and successful. The paper is concluded by discussing the limitations and implications of the study and future directions.
COUPLED HBO AND NBO VARIATIONS IN THE Z SOURCE GX 5-1: INNER ACCRETION DISK AS THE LOCATION OF QPOs

The simultaneous and coupled evolution of horizontal branch oscillation (HBO) and normal branch oscillation (NBO) in Z-type sources suggests that the production of HBO is connected to NBO and is caused by changes in the physical/radiative properties of the inner accretion disk, although there is a lack of substantial spectral evidence to support this. In this Letter, we present the results of an analysis of an RXTE observation of the Z source GX 5-1, where the 6 Hz NBO is simultaneously detected along with an HBO at 51 Hz. The variations in the intensity and the associated power density spectrum indicate that the HBO and NBO are strongly coupled, originating from the same location in the inner accretion disk. The absence of HBO and NBO in the lower energy bands, an increase in the rms amplitude with energy, and a smooth transition among them suggest that they are produced in the hot inner regions of the accretion disk. Based on a spectral analysis, we found a signature of changing or physically modified inner disk front during the coupled HBO and NBO evolution. We explore the various models to explain the observed phenomenon and propose that the NBO is affiliated to the oscillations in the thick/puffed-up inner region of the accretion disk.
Thermodynamic and dynamic anomalous behavior in the TIP4P/{\epsilon} water model

The model Tip4p/{\epsilon} for water is tested for the presence of thermodynamic and dy- namic anomalies. Molecular dynamic simulations for this model were performed and we show that for this system the density versus temperature at constant pressure ex- hibits a maximum. In addition we also show that the diffusion coefficient versus density at constant temperature has a maximum and a minimum. The anomalous behavior of the density and of the diffusion coefficient obey the water hierachy. The results for the Tip4p- are consistent with experiments and when compared with the Tip4p-2005 model show similar results a variety of physical properties and better performance for the dielectric constant.
How Experience Quality, Prior Knowledge and Perceived Value Affect Revisit Intention to Batavia Jakarta

Heritage tourism at Old City of Jakarta is still far behind from the Old City in Singapore and Shanghai, so this research was conducted to see the opportunity that revisit intention to Kota tua Jakarta can be increased through the right business strategy. This study aims to determine the effect of the experience quality and prior knowledge variables on revisit intention through perceived value. Primary data was obtained from the results of 406 tourist domestic questionnaires who visited the Jakarta Old Town. Data were collected from February to March 2022. The data is processed using SEM-PLS with SmartPLS application. By using purposive sampling method, it was concluded that the variables of experience quality and prior knowledge had a positive and significant effect.
Quality Analysis Of Digital Business Services In Improving Customer Satisfaction

Consumption behavior is changing as the times change, particularly in the technology era. The background problem it is difficult to predict which items or services will be in high demand. The background of this research is number of shuttered stores, malls, and supermarkets demonstrates that the internet era creates a place for consumer democracy. Then there is only one way out, and that is marketing reform. E-commerce (online buying and selling) as research objects has emerged in Indonesia, with one example being Shopee, which is focused on mobile applications and websites. It began as a Singaporean e-commerce platform under the Sea Group in 2015 and has since grown to Malaysia, Thailand, Indonesia, Brazil, et cetera. This study was carried out in order to detect and evaluate consumer behavior in the digital era in order to enhance sales. To depict the buying behavior in genuine words, a qualitative technique was adopted as method. By posing a few random questions on online retail purchases to respondents. To see the symptoms, around 113 people were chosen based on specific criteria. The findings indicate that customers in this day and age are ready for an online shopping strategy. There are gaps in almost every indicator except the first statement indicator from the Compensation dimension The primary factor is convenience. The results shows that convenience refers to marketing characteristics such as novelty like being able to do it anywhere, saving time and money, reduced rates, flexible payment options, and friendlier service.

Marganana DeLong, 1948 currently includes three species known to occur in the United States, Mexico and Guyana. In this paper, we describe a new species from Brazil – Marganana (Declivana) tetramaculata sp. nov. – which represents the first record of this genus for the country. A revised diagnosis of the subgenus Declivana is provided, along with detailed descriptions and illustrations of males and females of the new species. A key to the four species of Marganana is also provided.
Linking animal behaviour and tree recruitment: Caching decisions by a scatter‐hoarder corvid determine seed fate in a Mediterranean agroforestry system

Seed dispersal by scatter‐hoarder corvids is key for the establishment of important tree species from the Holarctic region such as the walnut (Juglans regia). However, the factors that drive animal decisions to cache seeds in specific locations and the consequences of these decisions on seed fate are poorly understood. We experimentally created four distinct, replicated habitat types in a Mediterranean agricultural landscape where the Eurasian magpie (Pica pica) is a common scatter hoarder: soft bare soil; compacted bare soil; compacted soil with a dense herbaceous cover; and soft linear bare soil made up of the irrigation furrows that separated the rest of the treatments. We also experimentally placed visual landmarks (stones, sticks and bunches of dry plants) to test if magpies use them to place seed caches. Walnut dispersal from feeders to the habitats was monitored by radiotracking and camera traps. A sowing experiment simulating natural caches tested the effect of caching type on seed germination and seedling emergence. Seed mass was controlled for the dispersal and sowing experiments. Magpies selected the two habitats with soft soil, and avoided the one with compacted soil, to cache nuts. Seed mass did not affect dispersal distance, germination or emergence; however, heavier seeds were cached more often under litter and in the habitat with herbaceous cover, whereas lighter seeds were more often buried in the soft bare soil habitat. Seed burial under soil or litter determined seed fate, as there was virtually no emergence from unburied nuts. There was no evidence of any effect of the visual landmarks. Synthesis. The consequences of seed caching for seedling early establishment are driven by a fine decision‐making process of the disperser. Magpies seemed to ponder the characteristics of the habitat and the seed itself to determine where and how to cache each nut. By doing so, magpies reinforced the quality of seed dispersal effectiveness, as they cached walnuts in locations that enhanced both seed survival and seedling emergence.
A practical analysis of balancing policies for rearranging data replicas in HDFS clusters

Data replication is the main fault tolerance mechanism implemented by the HDFS. The placement of the replicated data across the nodes directly influences replica balancing and data locality, which are essential to ensure high reliability and data availability. The HDFS Balancer is the official solution to perform replica balancing through data redistribution. In this work, we conducted a practical experiment to evaluate different policies for replica rearrangement, namely: datanode, blockpool, and custom. The evaluation results underline the behavior and the effectiveness of each policy. In addition, we investigated the cost of the HDFS Balancer operation and the performance and availability improvements promoted by a balanced replica distribution.
Identification of the Novel Gene Markers Based on the Gene Profile among Different Severity of Obstructive Sleep Apnea

Obstructive sleep apnea (OSA) is caused by repeated blockage of the upper respiratory airways during sleep. The traditional evaluation methods for OSA severity are yet limited. This study aimed to screen gene signatures to effectively evaluate OSA severity. Expression profiles of peripheral blood mononuclear cells in the different severities of OSA patients were accessed from Gene Expression Omnibus (GEO) database. A total of 446 differentially expressed genes (DEGs) were screened among the varying severities of OSA samples by analysis of variance (ANOVA) test. A total of 1,152 DEGs were screened between the pre- and post-treatment OSA samples by using t test. Overlap of the two groups of DEGs was selected (88 DEGs) for Metascape enrichment analysis. Afterwards, Mfuzz package was used to perform soft clustering analysis on these 88 genes, by which 6 clusters were obtained. It was observed that the gene expression condition of the cluster 3 was positively associated with OSA severity degree; also, the gene expression condition in cluster 4 was negatively correlated with OSA severity. A total of 10 gene markers related to OSA progression were selected from cluster 3 and cluster 4. Their expression levels and correlation were analyzed. The marker genes in cluster 3 and cluster 4 were examined, finding that most genes were significantly correlated with apnea hypopnea index (AHI). An accurate and objective assessment of the severity of OSA is of great significance for formulating follow-up treatment strategies for patients with OSA. In this paper, a set of marker genes that can detect the severity of OSA were screened by bioinformatics methods, which could be jointly used with the traditional OSA diagnostic index to achieve a more reliable OSA severity evaluation.
Unproceedings of the Fourth .Astronomy Conference (.Astronomy 4), Heidelberg, Germany, July 9-11 2012

The goal of the . Astronomy conference series is to bring together astronomers, educators, developers and others interested in using the Internet as a medium for astronomy. Attendance at the event is limited to approximately 50 participants, and days are split into mornings of scheduled talks, followed by 'unconference' afternoons, where sessions are defined by participants during the course of the event. Participants in unconference sessions are discouraged from formal presentations, with discussion, workshop-style formats or informal practical tutorials encouraged. The conference also designates one day as a 'hack day', in which attendees collaborate in groups on day-long projects for presentation the following morning. These hacks are often a way of concentrating effort, learning new skills, and exploring ideas in a practical fashion. The emphasis on informal, focused interaction makes recording proceedings more difficult than for a normal meeting. While the first . Astronomy conference is preserved formally in a book, more recent iterations are not documented. We therefore, in the spirit of . Astronomy, report 'unproceedings' from . Astronomy 4, which was held in Heidelberg in July 2012.

KINEMATICS OF STELLAR POPULATIONS IN POSTSTARBURST GALAXIES

Poststarburst galaxies host a population of early-type stars (A or F) but simultaneously lack indicators of ongoing star formation such as [O ii] emission. Two distinct stellar populations have been identified in these systems: a young poststarburst population superimposed on an older host population. We present a study of nine poststarburst galaxies with the following objectives: (1) to investigate whether and how kinematical differences between the young and old populations of stars can be measured, and (2) to gain insight into the formation mechanism of the young population in these systems. We fit high signal-to-noise spectra with two independent populations in distinct spectral regions: the Balmer region, the Mg ib region, and the Ca triplet when available. We show that the kinematics of the two populations largely track one another if measured in the Balmer region with high signal-to-noise data. Results from examining the Faber–Jackson relation and the fundamental plane indicate that these objects are not kinematically disturbed relative to more evolved spheroids. A case study of the internal kinematics of one object in our sample shows it to be pressure supported and not rotationally dominated. Overall our results are consistent with merger-induced starburst scenarios where the young population is observed during the later stages of the merger.
CONFRONTING MODELS OF DWARF GALAXY QUENCHING WITH OBSERVATIONS OF THE LOCAL GROUP

A number of mechanisms have been proposed to connect star-forming dwarf irregular galaxies with the formation of non-star-forming dwarf spheroidal galaxies (dSphs), but distinguishing between these mechanisms has been difficult. We use the Via Lactea (VL) dark matter only cosmological simulations to test two well-motivated simple hypotheses—transformation of irregulars into dSphs by tidal stirring and ram pressure stripping following a close passage to the host galaxy, and transformation via mergers between dwarfs—and predict the radial distribution and inferred formation times of the resulting dSphs. We compare this to the observed distribution in the Local Group and show that (1) the observed dSph distribution far from the Galaxy or M31 can be matched by the VL halos that have passed near the host galaxy at least once, though significant halo-to-halo scatter exists, (2) models that require two or more pericenter passages for dSph-formation cannot account for the dSphs beyond 500 kpc such as Cetus and Tucana, and (3) mergers predict a flat radial distribution of dSphs and cannot account for the high dSph fraction near the Galaxy, but are not ruled out at large distances. The models also suggest that for dSphs found today beyond 500 kpc, mergers tend to occur significantly earlier than dwarf–host encounters, thus leading to a potentially observable difference in stellar populations. We argue that tidal interactions are sufficient to reproduce the observed distribution of dSphs if and only if a single pericenter passage is sufficient to form a dSph.
The Roles of Arithmetic Fluency and Executive Functioning in Mathematical Problem-Solving

This study is conducted to further understand the direct and indirect contributions of executive functioning (visuospatial updating, verbal updating, inhibition, shifting) and arithmetic fluency to mathematical problem-solving in 458 fourth-grade students. Arithmetic fluency along with visuospatial and verbal updating were significant predictors of mathematical problem-solving at the end of grade 4. When the growth in mathematical problem-solving during grade 4 was analyzed, only arithmetic fluency directly and strongly contributed to students’ problem-solving at the end of grade 4. Inhibition and shifting (in combination with inhibition) were indirectly connected to mathematical problem-solving at the end of grade 4 via their arithmetic fluency. Arithmetic fluency plays a critical role and continues to do this in mathematical problem-solving. Furthermore, a decline in importance for visuospatial and verbal updating and increasing importance of inhibition and shifting (combined with inhibition) were found with regard to students’ ability to solve mathematical problems during grade 4.
The efficacy of negative pressure wound therapy after hepatopancreatobiliary surgery: A systematic review and meta-analysis

Objective: To evaluate the comparative influence of NPT and standard surgical dressing administration on incidence risk for surgical site infections, complications, and hospital re-admission after hepatopancreatobiliary surgery. Methods: Five databases were systematically searched according to PRISMA guidelines. These databases included Web of Science, MEDLINE, CENTRAL, EMBASE, and Scopus for eligible studies published prior to March 2021. With eligible studies, we conducted a random-effects meta-analysis to evaluate comparative outcomes such as superficial surgical infection, deep surgical infection, seroma incidence, hematoma incidence, and hospital re-admission in patients receiving NPT or standard surgical dressings after hepatopancreatobiliary surgery. Results: The search strategy yielded 963 studies, with six studies meeting inclusion criteria. Odds of superficial surgical site infection (OR: 1.58), deep surgical site infection (1.43), seroma complication (1.64), hematoma complication (0.40) were insignificantly different between patients receiving NPT and standard surgical dressing. The odds of hospital re-admission rate (2.37), however, were elevated in patients receiving standard surgical dressing relative to those receiving NPT. Conclusion: This meta-analysis shows that NPT usage slightly reduces risk of hospital readmission as compared to standard surgical dressing. We did not observe any significant effect of NPT on superficial, deep surgical infections, seroma, and haematoma outcomes following hepatopancreatobiliary surgery. These findings may aid clinicians in stratifying risk and selecting treatment strategy in patients undergoing hepatopancreatobiliary surgery.
Phase relations in K xFe 2-ySe 2 and the structure of superconducting K xFe 2Se 2 via high-resolution synchrotron diffraction

Superconductivity in iron selenides has experienced a rapid growth, but not without major inconsistencies in the reported properties. For alkali-intercalated iron selenides, even the structure of the superconducting phase is a subject of debate, in part because the onset of superconductivity is affected much more delicately by stoichiometry and preparation than in cuprate or pnictide superconductors. If high-quality, pure, superconducting intercalated iron selenides are ever to be made, the intertwined physics and chemistry must be explained by systematic studies of how these materials form and by and identifying the many coexisting phases. To that end, we prepared pure K${}_{2}$Fe${}_{4}$Se${}_{5}$ powder and superconductors in the K${}_{x}$Fe${}_{2\ensuremath{-}y}$Se${}_{2}$ system, and examined differences in their structures by high-resolution synchrotron and single-crystal x-ray diffraction. We found four distinct phases: semiconducting K${}_{2}$Fe${}_{4}$Se${}_{5}$, a metallic superconducting phase K${}_{x}$Fe${}_{2}$Se${}_{2}$ with $x$ ranging from 0.38 to 0.58, the phase KFe${}_{1.6}$Se${}_{2}$ with full K occupancy and no Fe vacancy ordering, and a oxidized phase K${}_{0.51(5)}$Fe${}_{0.70(2)}$Se that forms the PbClF structure upon exposure to moisture. We find that the vacancy-ordered phase K${}_{2}$Fe${}_{4}$Se${}_{5}$ does not become superconducting by doping, but the distinct iron-rich minority phase K${}_{x}$Fe${}_{2}$Se${}_{2}$ precipitates from single crystals upon cooling from above the vacancy ordering temperature. This coexistence of separate metallic and semiconducting phases explains a broad maximum in resistivity around 100 K. Further studies to understand the solubility of excess Fe in the K${}_{x}$Fe${}_{2\ensuremath{-}y}$Se${}_{2}$ structure will shed light on the maximum fraction of superconducting K${}_{x}$Fe${}_{2}$Se${}_{2}$ that can be obtained by solid state synthesis.
