Stability, transition and turbulence in rotating cavities

This chapter reviews striking features of boundary-layer instabilities induced by different mechanisms and related to transition to turbulence in rotating flows with walls. Besides its fundamental importance as a three-dimensional prototype flow, confined flow between rotating discs has been extensively examined because of its relevance to many industrial applications such as turbomachinery and engineering processes. Many studies using stability analyses and experiments have been devoted to the onset of unstable waves and to the mechanisms associated with them. Here, we focus on how numerical investigations may provide insights and complement experimental data and analytical results by providing the full velocity field in well-controlled flows within idealized configurations. Rotor-stator and rotating cavity with radial throughflow are investigated. At a critical rotation rate, axisymmetric and/or three-dimensional structures appear in the Bodewadt and Ekman layers. All features of the transitions in these rotating cavities are documented. A comparison of the wave numbers, frequencies, and phase velocities of the instabilities with available theoretical and experimental results shows that both Type II (or A) and Type I (or B) instabilities appear, depending on flow and geometric control parameters. Interesting patterns exhibiting the coexistence of circular and spiral waves are found under certain conditions.
Purified glycerin in balanced diets for chicken broilers from 8 to 21 days old

This paper aimed to evaluate the metabolizability, performance and economic viability of purified glycerin inclusion in balanced diets fed to chicken broilers from 8 to 21 days old. Two experiments were conducted. In the first experiment, 100 broilers (14 days old) were distributed in a completely randomized design into two treatments, with five replications of 10 broilers. Treatments consisted of a control diet and a test diet, in which purified glycerin replaced 10% of the control diet. In the second experiment, 200 broilers (8 days old) were distributed in a completely randomized design into four treatments (0, 2, 4 and 6% of purified glycerin inclusion), with five replications of 10 broilers. The weight gain, feed intake, feed conversion, final weight, apparent metabolizable energy (AME), nitrogen-corrected apparent metabolizable energy (AMEn), metabolizability coefficients of dry matter (DMMC), crude protein (CPMC) and gross energy (GEMC), and the cost of feed per kg of broiler produced were evaluated. The AME, AMEn, DMMC, CPMC and GEMC from the purified glycerin were 3790 and 3560 kcal/kg, and 83.72, 71.52 and 86.27%, respectively. The glycerin levels did not affect (p>0.05) any of the performance characteristics (weight gain, feed intake, feed conversion and final weight). The lowest feeding cost and the highest gross margin were obtained for broilers fed with 6% purified glycerin. The inclusion of 6% purified glycerin in balanced diets for broilers from 8 to 21 days old was technically and economically feasible.
NEUROPSYCHOLOGICAL FUNCTIONING IN OLDER ADULTS WITH CHRONIC KIDNEY DISEASE

Chronic Kidney Disease (CKD) is a condition that disproportionately affects older adults and is associated with high prevalence of vascular diseases and increased risk for the development of cognitive impairment. In the current study, we examined global cognition, verbal memory and executive functioning in older adults with CKD and compared their performance to ageand education-matched healthy controls. We also assessed the role of potential mediators/moderators of cognitive impairment in CKD, including metabolic disturbances, psychological distress, subclinical dementia and medication usage. Compared to controls, older adults with CKD exhibited worse executive functioning but relatively intact memory retention, a neuropsychological presentation that is consistent with vascular cognitive impairment. Poor cognitive performance in CKD was not associated with metabolic dysfunction or elevated psychological distress, and persisted after controlling for impaired global cognition and differences in medication usage. Future studies investigating the relationship between cerebrovascular pathology and neuropsychological functioning in CKD are warranted.
EVALUATION OF THE IMPACT OF TRAINING EFFORT IN WORKERS EMPLOYABILITY WITHIN THE INSTITUTIONAL SPANISH TRAINING MODEL

The association between quantity of training and employability was analysed through a non experimental research with two non equivalent groups. The operationalization of training quantity is considered to provide an indicator of training effort. Thus, training effort (number of courses) was analysed as the independent variable and employability as dependent variable (occupation indicators, activity enhancement and job performance). The results show that training is related to activity enhancement, specially when workers belong to a small/medium enterprise (SME) and/or to technical or qualified positions. A positive association between training and performance also appeared in the case of SMEs. Resumen Se analiza la asociación entre cantidad de formación y empleabilidad mediante una investigación no experimental con dos grupos no equivalentes. Se considera que la operativización de la cantidad de formación proporciona un indicador próximo al esfuerzo formativo realizado. Así, se estudió la variable independiente esfuerzo formativo (número de cursos) y la dependiente, empleabilidad (indicadores de ocupación, enriquecimiento de actividad y desempeño). Los resultados muestran que la formación está asociada al enriquecimiento de la actividad, sobre todo si los trabajadores pertenecen a una PYME y/o a puestos técnicos o cualificados. También hay una asociación positiva entre formación y desempeño en PYMES.
The Role of Self-Brand Connection on the Relationship Between Athlete Brand Image and Fan Outcomes

37 This research explores the role of athlete on-field and off-field brand image on consumer 38 commitment toward the athlete and associated team, preference by athlete’s sponsor, and the 39 mediating effect of consumers’ self-brand connection on these relationships. Data were 40 collected from fans of soccer players through a cross-sectional survey promoted on social 41 media platforms. A partial least squares structural equation model examined the direct effects 42 of both athlete brand dimensions on athlete commitment, team commitment and athlete 43 sponsor preference, and the indirect effects mediated via self-brand connection. The results 44 indicate that athlete on-field image is significantly related to athlete sponsor preference, while 45 the off-field image influences athlete commitment and team commitment. Self-brand 46 connection is influenced by athlete off-field image, and mediates the relationship between 47 off-field image and athlete commitment. This study contributes to a better understanding of 48 how to manage athlete brands and linkages between fans, athletes and associated entities. 49 50
Physiological Health of Common Bully (Gobiomorphus cotidianus) in the Tarawera and Rangitaiki Rivers of New Zealand: Evidence of Diminished Ecological Effects of Pulp and Paper Effluents in Wild Fish Populations

This study examined the comparative physiological health of the endemic New Zealand common bully (Gobiomorphus cotidianus) in the Tarawera and Rangitaiki Rivers. Bully were sampled downstream of pulp and paper effl uent inputs in the Tarawera River and compared with a similar inland population in the Rangitaiki River. Condition factor and liver somatic index did not differ between populations, but Tarawera River bullies possessed larger gonads. Haematological assessments found smaller erythrocytes with reduced haemoglobin content, and increased leukocyte concentrations in Tarawera River females. Male and female Tarawera River bullies had signifi cantly induced hepatic ethoxyresorufi n-O-deethylase (EROD) activity. Greater ovarian follicular steroid production was also found for Tarawera River females. Microscopic analysis of ovarian tissue samples found no histopathological abnormalities in either population and indicated a slightly advanced vitellogenic stage of development in the Tarawera River population. It is concluded that the difference in steroid production between populations was most likely linked to gonad size and developmental status. In line with the disappearance of physiological effects in recent controlled laboratory and mesocosm pulp and paper effl uent exposures, this study further demonstrates that, with the exception of EROD induction, characteristic pulp and paper effl uent effects are not obvious in wild Tarawera fi sh.
Near-infrared photometry of globular clusters towards the Galactic bulge: observations and photometric metallicity indicators

We present wide field JHKs photometry of 16 Galactic globular clusters located towards the Galactic bulge, calibrated on the 2MASS photometric system. Differential reddening corrections and statistical field star decontamination are employed for all of these clusters before fitting fiducial sequences to the cluster red giant branches (RGBs). Observed values and uncertainties are reported for several photometric features, including the magnitude of the RGB bump, tip, the horizontal branch (HB) and the slope of the upper RGB. The latest spectroscopically determined chemical abundances are used to build distance- and reddening-independent relations between observed photometric features and cluster metallicity, optimizing the sample size and metallicity baseline of these relations by supplementing our sample with results from the literature. We find that the magnitude different between the HB and the RGB bump can be used to predict metallicities, in terms of both iron abundance [Fe/H] and global metallicity [M/H], with a precision of better than 0.1 dex in all three near-IR bandpasses for relative metal-rich ([M/H]$\gtrsim$-1) clusters. Meanwhile, both the slope of the upper RGB and the magnitude difference between the RGB tip and bump are useful metallicity indicators over the entire sampled metallicity range (-2$\lesssim$[M/H]$\lesssim$0) with a precision of 0.2 dex or better, despite model predictions that the RGB slope may become unreliable at high (near-solar) metallicities. Our results agree with previous calibrations in light of the relevant uncertainties, and we discuss implications for clusters with controversial metallicities as well as directions for further investigation.
Finite element analysis of the beam strengthened with prefabricated reinforced concrete plate

Various strengthening methods were frequently carried out in the world to strengthen weaker cross section beams. In this study, one beam strengthened by bonding with a prefabricated plate which has 80 mm thickness underneath and one control beam were produced. The specimens were tested in the laboratory and a single load was applied on the middle of the beam. The results of the experiments were compared with the results obtained from the beam modelled with ANSYS finite element program. When the results of the experiments were compared with the modelled computer program, it was shown that the results of computer model gave similar results to the real behaviour.
Nonlinear cellular dynamics of the idealized detonation model: Regular cells

High-resolution numerical simulations of cellular detonations are performed using a parallelized adaptive grid solver, in the case where the channel width is very wide. In particular, the nonlinear response of a weakly unstable Zeldovich–Neumann–Doering (ZND) detonation to two-dimensional perturbations is studied in the context of the idealized one-step chemistry model. For random perturbations, cells appear with a characteristic size in good agreement with that corresponding to the maximum growth rate from a linear stability analysis. However, the cells then grow and equilibrate at a larger size. It is also shown that the linear analysis predicts well the ratio of cell lengths to cell widths of the fully developed cells. The evolutionary dynamics of the growth are nonetheless quite slow, in that the detonation needs to run of the order of 1000 reaction lengths before the final size and equilibrium state is reached. For sinusoidal perturbations, it is found that there is a large band of wavelengths/cell sizes which can propagate over very long distances (∼1000 reaction lengths). By perturbing the fully developed cells of each wavelength, it is found that smaller cells in this range are unstable to symmetry breaking, which again results in cellular growth to a larger final size. However, a range of larger cell sizes appear to be nonlinearly stable. As a result it is found that the final cell size of the model is non-unique, even for such a weakly unstable, regular cell case. Indeed, in the case studied, the equilibrium cell size varies by 100% with different initial conditions. Numerical dependencies of the cellular dynamics are also examined.

EFFECT OF OPTIMIZED TOTAL AGGREGATE GRADATION ON PORTLAND CEMENT CONCRETE FOR WISCONSIN PAVEMENTS

Most state paving specifications for portland cement concrete pavement allow a broad range of total aggregate gradation for concrete mixes. It has long been debated whether special efforts to control total aggregate gradation provide concrete improvements that justify potential increased costs. The results of an investigation examining the effect of optimizing total aggregate gradation on the properties of concrete used for paving in Wisconsin are reported. The investigation used concepts presented by Shilstone to optimize gradations consisting of carefully selected proportions of locally available aggregate. Unit weight, shrinkage, change in the water-to-cement ratio (w-c) at constant slump, change in slump at a constant w-c ratio, compressive strength, and possible segregation under vibration were measured in field test sections and laboratory mixes. This investigation showed that use of optimized total aggregate gradations instead of near-gap-graded gradations in pavement resulted in an increase in compressive strength of 10 to 20 percent, reduced water demand by up to 15 percent to achieve comparable slump, air contents achieved with 20 to 30 percent reductions in air entraining agent, potentially higher spacing factors in the air void system of hardened concrete, and reduced segregation following extended vibration (1 to 3 min). Not all efforts at gradation optimization in this study yielded measurable improvements in performance and the availability of local aggregates may still limit, to varying degrees, the ability to optimize. However a reasonable effort to optimize gradation can lead to significant mix benefits.
Effects of the Patience Training Program on Patience and Well-Being Levels of University Students.

In this study, the effect of patience training on patience and well-being levels of university students was examined. The sample group of the study consisted of 1.2. 3. and 4th grade students with a total of 30 students from Konya Necmettin Erbakan University, Eregli Education Faculty. For the collection of data, the Patience Scale developed by Schnitker (2010) and adapted to Turkish by Eliusuk and Arslan (2016) and the PERMA Well-being Scale developed by Kern (2015) and adapted to Turkish by Eliusuk (2016) was used. The measuring tools were applied to the experimental and control groups three times; the first before, the second one week after the and third three months after the end of the application. In the study, a patience education training consisting of 10 sessions was applied to the experimental group. No training was given to the control group. The Mann-Whitney U test and the Wilcoxon tests were used in the analysis of the data. As a result of the analyzes made at the end of the practice; significant differences where observed in individuals patience levels but no meaningful changes were seen in the well-being levels.

Response of spotted knapweed and grass to picloram and fertilizer combinations.

Spotted knapweed (Centaurea maculosa Lam.) has reduced forage production, increased soil erosion, and lowered biodiversity on millions of hectares of rangeland throughout the western United States. Objectives of this study were to quantify the interaction between picloram (4-amino-3,5,6-trichloropicolinic acid) and fertilizer on spotted knapweed density and grass yield. Four picloram rates (0.0, 0.14, 0.28, and 0.42 kg ha-1) and 4 fertilizer rates (N+P: 0.0+0.0, 10.5+12.2, 21.1+26.4, and 31.7+39.6 kg ha-1) were applied to 3 spotted knapweed infested rangeland sites in a factorial combination arranged in a randomized-complete-block design during the spring of 1994. Grass yield and spotted knapweed density were measured at peak standing grass crop in 1994 and 1995. Data were analyzed as a split-plot in time using analysis of variance. Picloram and fertilizer did not interact to affect either spotted knapweed density or grass yield. All picloram treatments reduced spotted knapweed density to nearly zero. By 1995, all picloram treatments increased grass yield by an average of 1,500 kg ha-1. Fertilization did not affect spotted knapweed density, but the highest rates increased grass yield on those sites with a substantial residual grass understory. Combining fertilizer with picloram may enhance grass yield on sites with a residual of highly productive grasses.
Use of traditional medicines in treatment of malaria among pregnant women in two urban slums in Enugu State, Nigeria

Malaria in pregnancy can lead to malaria-related anaemia, a condition that when left untreated, can result in death, especially among vulnerable populations such as pregnant women. Malaria can lead to severe anaemia and maternal and foetal death. This study aimed at exploring the perception and use of traditional medicine in the treatment of malaria among pregnant women in Ngenevu and Udi siding communities. A descriptive cross-sectional survey method was adopted for the study. Study population was 93 pregnant women purposively selected from two urban slums of Ngenevu and Udi siding, Enugu state. Structured questionnaire with reliability coefficient of 0.75 was used for data collection. Health Research Ethics Committee of University of Nigeria Teaching Hospital Enugu approved the study. Data collection was on the spot and was analysed with SPSS/IBM version 23. Inferential statistics was used to test the significance of income and educational level in determining the use of traditional medicine among pregnant women at p<0.05 level of significance. Majority (93.5%) of pregnant women in Udi siding and Ngenevu used traditional medicine to treat malaria. More than half (87.1%) perceived traditional medicine used in treating malaria as effective. Of the 32 women who reported to have experienced side effects, 81.3% had nausea and vomiting of which 57.7% and 42.3% are from Udi Siding and Ngenevu respectively. There was a significant relationship between income and level of education and use of traditional medicine in treatment of malaria in pregnancy (p<0.05). Pregnant women in the two urban slums utilized traditional medicine in treating malaria. Efforts should be intensified to discourage and reduce to the barest minimum the use of traditional medicines in treating malaria in pregnancy. This will help in stemming the tide of maternal and child mortality and morbidity in these urban slums.
Dynamically consistent shallow‐atmosphere equations with a complete Coriolis force

Shallow‐atmosphere equations retaining both the vertical and horizontal components of the Coriolis force (the latter being neglected in the traditional approximation) are obtained. The derivation invokes Hamilton's principle of least action with an approximate Lagrangian capturing the small increase with height of the solid‐body velocity due to planetary rotation. The conservation of energy, angular momentum and Ertel's potential vorticity are ensured in both quasi‐ and non‐hydrostatic systems.
Conservatism Determinants: Evidence from Indonesia Manufacturing Sector

Accounting conservatism lead the preparation of ﬁnancial statements which in the act of recognize cost or loss estimates, but do not immediately recognise future revenues or proﬁts even though the probability of occurrence is large. This study aims to measure the factors that encourage companies to apply the principle of conservatism in the manufacturing industry sector with regression methods. Then it was found that; managerial ownership structure, institutional ownership structure, ﬁnancial distress, and company size simultaneously and partially do not have a signiﬁcant inﬂuence on the application of the principle of accounting conservatism. The existence of asymmetry information on ﬁnancial statements has thought to have an impact on the difﬁcultyofmeasuringthebasisofconservatismactions,as well as the determinants of factors beyond observation. Therefore, it was expected that the process of presenting ﬁnancialstatementscouldreﬂectmanagementperformanceindependentlyinorderto provide information according to its occurrence
