Enhanced settling in activated sludge: design and operation considerations
Authors: Daigger Glen T. , Redmond Eric , Downing Leon 
Published: June 2018

Abstract
Settling of activated sludge particles has long been the key to successfully achieving secondary treatment. While soluble products can be converted to particulate components via microbial reactions in the activated sludge process, it is the subsequent removal of these particulate components that is the key to achieving ultimate water quality criteria. An understanding of the operating parameters for selecting good settling activated sludge particles was first documented in the 1970s and 1980s. An understanding of the growth pressures that can be imposed on filamentous organisms, and the impacts of selector zones in general, allowed the design and operation of activated sludge processes to routinely achieve good sludge settleability. More recently, research has identified what could be the next evolution in flocculant growth, with the growing interest in aerobic granular sludge. Aerobic granular sludge is purported to provide superior settling properties, and many of the growth pressures identified for aerobic granular sludge are also present in activated sludge systems. These enhanced settling sludge systems are gaining significant interest, but the factors leading to enhanced sludge settleability could be present in historical and existing systems. Three facilities were evaluated that exhibited enhanced settleability (i.e. sludge volume indices of less than 70 mL/g the majority of the time) to determine how these enhanced settling sludges compare to typical settling curves from the literature. The enhanced settling sludge facilities exhibit key differences related to surface overflow rate, return activated sludge (RAS) pumping requirements, and sensitivity to solids concentration that are critical for developing effective settling designs for enhanced settling sludge facilities. As more facilities aim to achieve enhanced settling sludge for intensification of infrastructure, it will be important to carefully consider historic settling curves and to develop site-specific settling criteria when possible.
COMBINATION OF THE ISOCHORIC METHOD AND THE EXPANSION METHOD TO DETERMINE DENSITIES OF HYDROGEN AT TEMPERATURES UP TO 500°C
Authors: Supriatno Supriatno 
Published: June 2018

Utilization of hydrogen as an alternative fuel is promising because it is environmentally friendly. Hydrogen system design requires accurate hydrogen densities. The density of hydrogen is determined based on experimental data. For gases that have a low density such as hydrogen, the effective measurement method is required. An apparatus has been designed to measure PVT properties of hydrogen at pressures up to 1 MPa and temperatures up to 500ºC. The apparatus uses a combination of isochoric and expansion methods. The method doesn’t need a measurement of pressures and temperatures along the isochoric line as required usually in the isochoric conventional method. Moreover, it doesn't need direct measurements of gas mass and gas volume. The volume was determined by measuring nitrogen at a pressure of 0.5 MPa and at temperatures up to 500ºC and by using Span’s equation of state. Measurements of hydrogen have been performed at a pressure up to 0.7 MPa and temperatures up to 498.217ºC. Densities of hydrogen obtained from the present measurement are compared with that obtained from calculation of Leachman's equation of state. Maximum deviation is 1.42% at a temperature of 498.217ºC and at a pressure of 0.2947 MPa and minimum deviation is 0.11% at temperature and pressure of 399.461ºC and 0.6981 MPa respectively.

OBJECTIVE
Diabetes distress among patients from ethnic minorities is still poorly understood. We investigated the association between ethnicity and diabetes distress among ethnic minority groups of people with type 2 diabetes in the Netherlands, focusing on the possible effects of glycemic control, lifestyle factors, cardiovascular risk factors, and diabetes complications.

RESEARCH DESIGN AND METHODS
Cross-sectional data from the Dutch Diabetes Pearl cohort included people with type 2 diabetes from primary, secondary, and tertiary diabetes care programs. We used the 20-item Problem Areas in Diabetes Survey (PAID) scale to assess diabetes distress; a score ≥40 is considered to represent high distress. Ethnicity was estimated on the basis of country of birth. Sociodemographic and lifestyle data were self-reported; cardiovascular and metabolic data were retrieved from medical charts. Logistic regression analysis determined the association between ethnicity and diabetes distress, with Caucasians as the reference group.

RESULTS
Diabetes distress scores and ethnicity were available for 4,191 people with type 2 diabetes: 3,684 were Caucasian, 83 were Asian, 51 were Moroccan, 92 were African, 134 were Latin American, 46 were Turkish, and 101 were Hindustani-Surinamese. Overall, participants in minority groups had worse health outcomes than those of Caucasian descent, and diabetes distress was more prevalent (ranging from 9.6 to 31.7%, compared with 5.8% among Caucasians), even after adjusting for age, sex, education level, alcohol use, smoking, BMI, lipid profile, HbA1c, medication use, and the presence of diabetes complications.

CONCLUSIONS
Among people with type 2 diabetes in the Netherlands, ethnicity is independently associated with high diabetes distress. Further research is warranted to explain the higher prevalence of diabetes distress in minority groups and to develop effective interventions.
Public Preferences regarding Data Linkage for Health Research: A Discrete Choice Experiment
Authors: Aitken Mhairi , McAteer Gareth , Davidson Sara , Frostick Clive , Cunningham-Burley Sarah 
Published: June 2018

The potential for data collected in the public and private sector to be linked and used in research has led to increasing interest in public acceptability of data sharing and data linkage. The literature has identified a range of factors that are important for shaping public responses and in particular has noted that public support for research conducted through data linkage or data sharing is contingent on a number of conditions being met. In order to examine the relative importance of these conditions a Discrete Choice Experiment (DCE) was conducted via an online questionnaire among members of Ipsos MORI’s online panel in Scotland. The survey was completed by 1,004 respondents. Overall the two most influential factors shaping respondents’ preferences are: the type of data being linked; and, how profits are managed and shared. The type of data being linked is roughly twice as important as who the researchers are. There were slight differences across age groups and between genders and slight differences when comparing respondents with and without long term health conditions. The most notable differences between respondents were found when comparing respondents according to employment and working sector. This study provides much needed evidence regarding the relative importance of various conditions which may be essential for securing and sustaining public support for data-linkage in health research. This may be useful for indicating which factors to focus on in future public engagement and has important implications for the design and delivery of research and public engagement activities. The continuously evolving nature of the field means it will be necessary to revisit the key conditions for public support on an ongoing basis and to examine the contexts and circumstances in which these might change.

Published: June 2018

Integration of Kazakhstan into the world educational space makes it necessary to align with the requirements of the state and society to orient the education of the younger generation on the development of competencies that promote the concept of "education through life". Significant changes in the priorities in school education in the world in recent years require a reorientation to a competence approach, continuous self-education, mastering new information technologies, the ability to cooperate and work in groups.
The purpose of our research is to improve the quality of school mathematics education with the help of competence-oriented assignments.
For the analysis of the analyzed targets, the analysis of the native and chemical methapods is analyzed; the systematic analysis of the mathematical encounters and the reconstruction of the infectious information with the help of hypotheses and analgesia, comparison and hypnotism, analysis and synthesis, modeling and mental ex- periment; Diagnostic methods with the goal of designing the formation of coarse mnogoapektnyh central design of the person; the isolation of the criteria for the design of a diagonal quality - a system of colors that characterize the structure of the complex of personalities in the world; methods of observation, caution, a systematic analysis of the results.
When solving competency-oriented tasks, students are able to use and notice the general in the private, to reveal the significance of established facts and patterns, to form and develop the basic mental operations.
The methods for solving competence-oriented tasks should not only promote the development of skills and skills that meet the program requirements, but also the development of creative cognitive activities. These include tasks that familiarize schoolchildren with non-standard methods of reasoning, but do not require the extension of the curriculum material.
The nature of the representation of competence-oriented tasks takes into account the psychological characteristics of students' perception of information. In particular, it is desirable that the conditions of the problems allow rather simple graphic or "subject" illustrations.
In conclusion, we note that competence-oriented tasks should include entertaining tasks that are diverse in terms of the story, in the formulation of questions, in the methods of solutions. It is desirable to include in the system tasks, the solution of which is divided in time and whose purpose is the development of certain skills and abilities, the consolidation of methods of reasoning, methods of solving problems, the development of spatial representations, the formation and development of mental operations, such as: analysis, synthesis, comparison, classification, etc.
A Theoretical Framework for a Dynamic Team Learning and Adaptation System
Authors: Sexe Frederick S. 
Published: June 2018

This paper will discuss a model for team learning and adaptation by applying sociotechnical and cognitive systems concepts to a model previously developed by [1] to facilitate double-loop learning in teams and organizations. Organizational knowledge assets will be explained relative to team learning followed by an explanation of the sociotechnical system that the model is based upon. An overview of the team cognitive systems model will be provided as a precursor to explaining the learning and adaptation system. The team learning and adaptation model combines sociotechnical and cognitive systems elements to provide a model explaining how team learning at the tactical level can be aligned with other organizational resources while aligning these efforts towards organizational strategy. The proposed model also provides a holistic means for implementing a problem-solving methodology within the sociotechnical and cognitive systems contexts.
The aim of this paper is to aid practitioners seeking to improve how his or her team learns, collaborates, and innovates at all levels of the organization. The paper is geared mainly towards practitioners interested in improving his or her team's performance. Academics interested in team learning and knowledge sharing may also find the model of interest in academic pursuits related to team learning and adaptation. Practitioners can use this model to identify shortcomings in team learning and adaptation performance relative to specific work requirements. Academicians can use the model to explain sociotechnical and environmental interactions relative to how teams perform learning and adapting behaviors.
Deslocativización y abstracción diacrónica de frases preposicionales con a. Efecto dominó en un cambio léxico-semántico
Authors: Flores Dávila Rodrigo 
Published: June 2018

En este artículo se analiza, desde una perspectiva diacrónica, la relación entre dos procesos de cambio léxico-semántico experimentados por frases con la pauta a +frase nominal: deslocativización y abstracción. El principal hallazgo de esta investigación es que, a lo largo de la historia, el signi- ficado básico locativo de esta clase de frases disminuyó en beneficio del no locativo; este hecho propició el incremento de frases nominales con carácter abstracto, en perjuicio de las frases nominales con carácter concreto. El interés de estos cambios léxico-semánticos radica en que se cumplieron a modo de “efecto dominó” una primera deslocativización y una subsecuente abstracción.

Published: June 2018

Â Concrete is the most extensively used construction material around the world and its properties have been undergoing changes through technological advancements. Varieties of concrete have been developed to enhance the different properties of concrete. An investigation in to the potential use of partial replacement of mineral admixture in high performance concrete (HPC) has carried out. The engineering properties of fresh and hardenedconcrete are obtained by conducting test on slump, vee-bee, compaction factor and compressive strength, flexural strength, spilt tensile strength and modulus of elasticity, in this project partial replacement of cement bymetakaolin and rice husk ash been used for varying replacement of 0+0%, 5+105, 7.5+10%,10+10%,5+12.5%, 10+12.5%, 5+15%, 7.5+15%,Â and 10+15%for high strength, workability and also an eco-friendly by less emission of co2. It has been concluded that strength development of concrete blended with metakaolin and rice hush ash was enhanced. It was found that in 7.5% replacement of metakaolin and 12.5% replacement of rice husk ash appear to be the optimum replacement which exhibited more strength. This investigation has proved that the MK and RHA concrete can be used as structural concrete at suitable replacement percentage.Â
Evaluation of self-injurious behavior, thermal sensitivity, food intake, fecal output, and pica after injection of three buprenorphine formulations in rats (Rattus norvegicus)
Authors: Allen Molly , Johnson Rebecca A. 
Published: June 2018

Abstract
OBJECTIVE To assess effects of buprenorphine hydrochloride (BH), sustained-release buprenorphine (SRB), and high-concentration buprenorphine (HCB) formulations in healthy rats.
ANIMALS 8 Sprague-Dawley rats.
PROCEDURES In a crossover-design study, rats received BH (0.05 mg/kg), SRB (1.2 mg/kg), HCB (0.30 mg/kg), or 5% dextrose solution (0.2 mL/kg), SC, once. Self-injurious behavior and thermal sensitivity (hind limb withdrawal latencies) were assessed prior to injection (time 0) and 1, 4, 8, 12, and 24 hours after injection. Food intake, kaolin intake, and fecal output were measured over 12-hour light and dark periods before and after each treatment. Values were compared among treatments and time points.
RESULTS Self-injurious behavior was detected with all buprenorphine treatments; scores were greater at all time points during the 12 hours after HCB and 24 hours after SRB administration than at time 0. Percentage change in hind limb withdrawal latencies from time 0 was higher with BH and HCB 1 hour after injection than at other time points. Postinjection light-period food intake was higher (BH and HCB) and dark-period food intake was lower (BH, HCB, and SRB), compared with preinjection values for the same treatments. For SRB, postinjection light-period kaolin intake was greater than the preinjection value, and postinjection light- and dark-period kaolin intake was greater than that for other treatments.
CONCLUSIONS AND CLINICAL RELEVANCE Hypoalgesic effects were briefly observed after administration of BH or HCB in healthy rats; adverse effects were detected in some rats with all buprenorphine formulations. Studies comparing effects of BH, SRB, and HCB in rats undergoing surgery or other noxious stimuli are indicated to determine clinical benefits in this species.
Effects of a nutrient-enriched water on water intake and indices of hydration in healthy domestic cats fed a dry kibble diet

Published: June 2018

Abstract
OBJECTIVE To evaluate the effects of drinking nutrient-enriched water (NW) on water intake and indices of hydration in healthy domestic cats fed a dry kibble diet ad libitum.
ANIMALS 18 domestic shorthair cats.
PROCEDURES Group-housed cats were assigned to tap water (TW; n = 9) or NW (9) groups. All cats received TW at baseline (days −7 to −1). No changes were made to the food-water regimen for the TW group. The NW group received NW instead of TW from days 0 through 10, then received TW and NW in separate bowls (days 11 through 56). Food intake was measured through day 10; liquid consumed by drinking was measured throughout the study. Blood and urine samples were collected at predetermined times for analyses; 48-hour urine collection (days 28 through 30 or 31 through 33) was performed to assess output volume and aid endogenous creatinine-based glomerular filtration rate (GFR) determination. Data were analyzed with linear mixed-effects models.
RESULTS Baseline TW and calorie intake were similar between groups. The NW treatment was significantly associated with increased liquid consumption during the treatment phase. Mean urine output was significantly higher in the NW group (15.2 mL/kg/d) than in the TW group (10.3 mL/kg/d). Mean GFR (1.75 vs 1.87 mL/min/kg, respectively) did not differ between groups. Effects of treatment and time were each significant for urine specific gravity and osmolality and urine creatinine, phosphate, and urea nitrogen concentrations, with lower values for the NW group.
CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that consumption of the NW can increase liquid intake and improve measures of hydration in healthy cats. These effects may offer health benefits to some cats in need of greater water consumption.
Evaluation of a fluorescence resonance energy transfer quantitative polymerase chain reaction assay for identification of gyrA mutations conferring enrofloxacin resistance in canine urinary Escherichia coli isolates and canine urine specimens

Published: June 2018

Abstract
OBJECTIVE To evaluate a fluorescence resonance energy transfer quantitative PCR (FRET-qPCR) assay for detection of gyrA mutations conferring fluoroquinolone resistance in canine urinary Escherichia coli isolates and canine urine specimens.
SAMPLE 264 canine urinary E coli isolates and 283 clinical canine urine specimens.
PROCEDURES The E coli isolates were used to validate the FRET-qPCR assay. Urine specimens were evaluated by bacterial culture and identification, isolate enrofloxacin susceptibility testing, and FRET-qPCR assay. Sensitivity and specificity of the FRET-qPCR assay for detection of gyrA mutations in urine specimens and in E coli isolated from urine specimens were computed, with results of enrofloxacin susceptibility testing used as the reference standard.
RESULTS The validated FRET-qPCR assay discriminated between enrofloxacin-resistant and enrofloxacin-susceptible E coli isolates with an area under the receiver operating characteristic curve of 0.92. The assay accurately identified 25 of 40 urine specimens as containing enrofloxacin-resistant isolates (sensitivity, 62.5%) and 226 of 243 urine specimens as containing enrofloxacin-susceptible isolates (specificity, 93.0%). When the same assay was performed on E coli isolates recovered from these specimens, sensitivity (77.8%) and specificity (94.8%) increased. Moderate agreement was achieved between results of the FRET-qPCR assay and enrofloxacin susceptibility testing for E coli isolates recovered from urine specimens.
CONCLUSIONS AND CLINICAL RELEVANCE The FRET-qPCR assay was able to rapidly distinguish between enrofloxacin-resistant and enrofloxacin-susceptible E coli in canine clinical urine specimens through detection of gyrA mutations. Therefore, the assay may be useful in clinical settings to screen such specimens for enrofloxacin-resistant E coli to avoid inappropriate use of enrofloxacin and contributing to antimicrobial resistance.
Amount of skin shrinkage affecting tumor versus grossly normal marginal skin of dogs for cutaneous mast cell tumors excised with curative intent

Published: June 2018

Abstract
OBJECTIVE To assess differences in skin shrinkage between grossly visible tumor and grossly normal marginal skin of dogs for cutaneous mast cell tumors (MCTs) excised with curative intent and to determine an equation to estimate postexcisional gross tumor margins from preexcisional measurements and vice versa.
SAMPLE 19 cytologically confirmed and surgically excised cutaneous MCTs obtained from dogs.
PROCEDURES Tumors were measured in craniocaudal and dorsoventral directions before excision, immediately after excision, and after fixation in formalin. Both grossly visible tumor and surrounding grossly normal skin that comprised the surgical margin were measured at each time point. Percentage of shrinkage was compared among time points and between the tumor and surrounding grossly normal skin. Patient and histopathologic variables were correlated to skin shrinkage.
RESULTS Overall shrinkage was 17.70%. The amount of shrinkage within the grossly visible tumor (4.45%) was less than that within the surrounding grossly normal skin (24.42%). Most of the shrinkage occurred immediately after excision. There was no effect of age, sex, completeness of excision, or degree of edema. Accuracy of an equation to estimate postexcisional margins from preexcisional measurements was only 18.4%.
CONCLUSIONS AND CLINICAL RELEVANCE Grossly evident MCTs of dogs shrunk less than did the grossly normal surrounding skin. Although an equation to estimate postexcisional margins from preexcisional measurements could be derived, it likely would need to contain additional variables not included in the study reported here. Until such an equation exists, care must be used when extrapolating surgical margins from histologic margins and vice versa.
