Wall Effect on A Spherical Particle Settling along The Axis of Cylindrical Tubes Filled with Carreau Model Fluids

The effect of finite boundaries on the drag experienced by a rigid sphere settling along the axis of cylindrical tubes filled with Carreau model fluids has been examined systematically. Specifically, the governing equations along with the boundary conditions were numerically solved over a wide range of conditions, sphere-to-tube diameter ratio: 0-0.5; Reynolds number: 1-100; Carreau number: 0.1-100; and power law index: 0.2-1. As expected, the presence of finite boundaries leads to an increase in the drag force exerted on a falling sphere thereby retarding its descent due to the obstruction caused by the sphere and the corresponding changes in the velocity field close to the sphere. Nonetheless, the wall effect is less significant as the power law index decreases and/or the Carreau number increases, i.e., increasing extent of shear-thinning behavior. Besides the impact on the hydrodynamic drag, the severity of bonding walls affects the wake characteristics. The present calculations show good agreement with experimental reports available in the literature.

THE CHARACTERIZATION OF SOME WILD SPECIES OF Helianthus FOR SOME MORPHOLOGICAL TRAITS

SUMMARY This present investigation was undertaken to determine some plant characters in six wild Helianthus genotypes and their test hybrids in 2007 and 2008. Helianthus petiolaris spp. petiolaris (E-142), Helianthus neglectus (E- 017) and four wild Helianthus annuus (E-060, E-173, E-174 and E-175) were used as the material. The morphological characters observed in the wild Helianthus genotypes were plant height, head diameter, lateral number, number of days to 50% flowering, flowering period length, and presence of anthocyanin in the cotyledons. In the second year, test hybrids of E-017, E-142, E-173 and E- 175 with the female line 2453-A were evaluated for seed yield, seed weight and some morphological traits. The results showed that plant height, head diameter and lateral number for these wild genotypes ranged from 63 to 171 cm, 2.4 to 8 cm and 43 to 324.3, respectively. The wild sunflower genotypes needed 82-105 days after emergence to reach 50% flowering and had flowering periods of 67-91 days. E-142 (Helianthus petiolaris spp. petiolaris) and its test hybrid with the female line 2453A were similarly in the early group for days to 50% flowering. E-017 (Helianthus neglectus) and its test hybrids were similarly late for days to 50% flowering. Interestingly, although E-173 had medium plant height, its test hybrid had the shortest plants.
Rolling technique for treatment of left displacement of the large colon in horses : 11 cases ( 2004-2009 )

The left displacement of the large colon, a condition that commonly occurs in horses, has two clinical manifestations. Different treatments including medical treatment, rolling the horse under general anesthesia or surgical correction have been recommended. The diagnosis can often be made by rectal examination and confirmed by percutaneous ultrasonography. During the period between 2004 and 2009, 11 horses were treated for left displacement of the large colon by rolling the horses under general anesthesia, using a slightly different technique than the ones previously described. The clinical case selection was based on rectal palpation confirmed with ultrasonogram. Nine animals were successfully treated and two had to be submitted to surgery after three attempts of rolling. No short or long term complications were observed after the procedure. Only one animal had a recurrence of the clinical manifestation 10 months after the first treatment and was successfully rolled once again. Despite a bit different from the other rolling procedures, this also proved to be an effective procedure. Rolling a horse even when attempted more than once showed to be a safe procedure, however, we reinforce the need for special attention following the procedure in order to establish proper emergency procedures in case complications occur.
Workforce Skills in the Eyes of the Employers

The objective of this note is to present the results of the recently completed employer skills survey, and to discuss their policy implications. The analysis finds that there is a skills shortage in Georgia despite high unemployment. It is difficult for employers, especially in the modern sector, to find workers with the required skills. Employers demand not only ‘hard’ technical skills, but also ‘soft’ social and behavioural skills (such as openness to experience) as well as higher-order cognitive skills (such as problem solving and creative thinking). And these are the skills that young Georgians often lack. Box one summarizes the main results of the analysis and shows the core employability skills that young workers lack most often. The note is organized as follows. Section one looks at the supply of and demand for skills, and shows that, despite high unemployment, there is a skills shortage. Section two examines the demand for skills more closely. It identifies skills that determine the employers hiring decisions, and skills that young job applicant most frequently lack. Section three focuses on firm organized training as a way of coping with a skills shortage. Section four concludes and discusses policy implications of the analysis.
Pre-Service Turkish Teachers' Metaphorical Perceptions Regarding the Concepts of "Instructional Technology" and "Teaching Material".

In this study, it was aimed to determine the perceptions of pre-service Turkish teachers (PTT) regarding the concepts of instructional technology and teaching material through metaphors. Within the scope of this aim, what the metaphors used by PTTs for the concepts of instructional technology and teaching material were and under which categories the metaphors used by them for these concepts were collected were investigated. The phenomenology design, one of the qualitative research methods, was used in the study. Data were collected from a total of 152 PTTs studying in the first, second, third and fourth grades of Çukurova University Faculty of Education Turkish Education Department. Data were collected by means of a form intended for completing the statements of "Instructional technology is like. because. " and "Teaching material is like . because. " and analyzed using the content analysis technique. As a result of the study, the metaphors examined for the concept of instructional technology were collected in 9 categories while the metaphors for the concept of teaching material were collected in 5 categories. The categories for instructional technology are informative/information source, tool/vehicle, requirement, permanence, change, attractiveness, process, development, and limitlessness, and the categories for teaching material are tool/vehicle, requirement, informative/information source, attractiveness and permanence.
Induction of Apoptosis by Resveratrol in Cancer Cells During Combination Treatment with Nutlin-3 and TGF—β

INTRODUCTION. Resveratrol (3, 4’, 5-trihydroxy-trans-stilbene) is a naturally occurring compound found mainly in the skins of grapes and various other fruits and nuts. Resveratrol (RV) has been previously studied and found to work through various mechanisms and produce anti-inflammatory, antiviral and anticancer effects (1,2,3). Previous studies have shown that RV promotes p53dependent apoptosis via a Ras-MAPK signal transduction pathway by increasing the levels of serine phosphorylation of p53 (4). Alteration of expression of Bcl2 family proteins, loss of mitochondrial function, release of cytochrome c, and activation of caspases are also believed to be involved in the RV induced cell death (5).
The solubility pump of carbon in the subtropical gyre of the North Atlantic

The subduction of carbon is examined using abiotic models of the solubility pump in the subtropical gyre of the North Atlantic. The importance of the seasonal cycle of the mixed layer, and advection of carbon, is examined using sensitivity experiments with a Lagrangian model of the carbon system. The rate of subduction of carbon is found to be strongly influenced by the gradients in mixed-layer thickness over the gyre and, to a lesser extent, modified by the end of winter bias in the properties of subducted fluid. A seasonally-cycling geochemical model of the carbon system is then developed for the North Atlantic. The model is diagnosed to examine the seasonal exchange in carbon between the atmosphere and ocean induced by the seasonal warming and cooling. There is a net annual air-sea flux of carbon into the subtropical gyre of the model due to undersaturation ofpco, with respect to the local equilibrium with the atmosphere. The undersaturation is due to advection of carbon by the circulation. Along the path of the Gulf Stream, northward advection and cooling of the low latitude waters is so rapid that the surface waters are significantly undersaturated in carbon. Due to its long equilibration period, there is a resultant air-sea flux of carbon dioxide over the northern flank and interior of the subtropical gyre. Warm, low carbon water from the tropics is fluxed into the southern flank of the subtropical gyre in the Ekman layer, inducing an oceanic uptake of carbon there. The model experiments suggest that it is necessary to account for advection to close the carbon budget in the observed time-series measurements at Bermuda.
IMIDAZOLINONE DEGRADATION IN SOIL IN RESPONSE TO APPLICATION HISTORY

Accelerated herbicide degradation consists in its faster degradation in areas where it has been previously applied, due to the adaptation of microbial population to that particular compound. Accelerated degradation can reduce herbicide persistence and reduce its efficacy in soil. The objective of this study was to investigate if imidazolinone herbicides have enhanced microbial degradation in rice paddy soils. A laboratory experiment was conducted, evaluating the CO2 evolution rate from soils with and without history of herbicide application (imazapyr + imazapic and imazethapyr + imazapic), incubated with imidazolinone herbicides: imazethapyr, imazapyr, imazapic, imazamethabenz, imazamox and an untreated check. The amount of CO2 released from the soil was measured. As a result, the prior application of imidazolinones does not stimulate microbial degradation of herbicides from the same chemical group.
Title Global Binary Optimization on Graphs for Classification of High-Dimensional Data Permalink

This work develops a global minimization framework for segmentation of high dimensional data into two classes. It combines recent convex optimization methods from imaging with recent graph based variational models for data segmentation. Two convex splitting algorithms are proposed, where graph-based PDE techniques are used to solve some of the subproblems. It is shown that global minimizers can be guaranteed for semisupervised segmentation with two regions. If constraints on the volume of the regions are incorporated, global minimizers cannot be guaranteed, but can often be obtained in practice and otherwise be closely approximated. Experiments on benchmark data sets show that our models produce segmentation results that are comparable with or outperform the state-of-the-art algorithms. In particular, we perform a thorough comparison to recent MBO (Merriman-Bence-Osher) [49] and phase field methods, and show the advantage of the algorithms proposed in this paper.
Consumer Preferences and Factors Affecting Consumer Purchases of Pomegranates

Specialty crop production account for about 70% of Florida agriculture and is of great economic importance to the state. The farmers in Florida are facing competition from other US States and Mexico and this is pushing them to look for other specialty crops that can be grown in Florida and diversify their investment. Pomegranate is the specialty crop that farmers in Florida have expressed interest in the last years and currently farmers have started to experiment growing pomegranates in their farms. In this study we use a sample of data obtained from an online survey and the focus of our study is to analyze the consumers’ behavior and determine the factors that are significant in the consumption of the pomegranate. Besides preferences and tastes of consumers in the study we consider other factors such as health benefits due to the high nutritional value of pomegranates.
The Deterioration of Newsprint and Implications for Its Preservation

Much of the information we have about history, science, culture, and civilization for the last 500 years is stored in paper-based formats. Unfortunately, changes in the technology of papermaking in the 19th century rendered the survival of much of the recorded information of a hundred year period problematic. As its use spread in Europe from the late 1400s, paper was traditionally prepared from rag fibers of cotton or linen. Such paper was quite stable, and many books and documents not subjected to physical or environmental abuse have survived in quite good condition. The demand for paper eventually exceeded the supply of rags, and the use of other sources of cellulosic fibers such as straw and grasses was explored. It was not until the late 19th century, however, with the development of mechanical equipment and chemical processes capable of converting wood to pulp that the most abundant source of cellulose could be exploited. Decades later, the relative impermanence of paper produced by
A Modified Fama and French (1993) Three-factor Asset Pricing Model: Evidence from the UK Equity Market

The objective of this study is to examine the modified Fama and French (1993) three-factor asset pricing model, suggested by Cremers et al. (2012), in the UK equity market, over the period from October 1980 to June 2015. The article follows the correct Lewellen et al. (2010) framework for evaluating asset pricing models. In contrast to Michou et al. (2007) and Gregory et al. (2013), the results suggest the use of the modified Fama and French (1993) three-factor asset pricing model in practical applications that require the estimation of expected returns in the UK equity market. The results are robust using the same sample period in Gregory et al. (2013). Overall, the result suggests to follow the correct Lewellen et al. (2010) framework for evaluating asset pricing models in pricing the UK equity market returns.
Assessing the Influence of Attitude Towards Mathematics on Achievement of Grade 10 and 12 Female Students in Comparison with Their Male Counterparts: Wolkite, Ethiopia

Exploring why more males achieve more than females in mathematics at secondary school level when there appear to be no gender differences in the achievement at earlier years is worthy of investigation. The aim of this study was to investigate the influence of attitude towards mathematics on the achievement of female students in comparison with their male counterparts and also to examine the relationship between attitudes and mathematics achievement. The participants of the study were 240 grade ten and 127 grade twelve students of General Secondary and Preparatory School in Wolkite Town. These students were selected using stratified random sampling technique. Attitude towards Mathematics Inventory (ATMI) was used to measure students’ attitude, whereas their achievement was measured by the score obtained from Mathematics Achievement Test (MAT). Descriptive Statistics, Multiple Linear Regression Models, Independent – samples t – test, and Pearson Correlation Coefficient were employed to analyze the collected data by using a Statistical Package for Social Sciences (SPSS) version 20. The results, in both grade levels, unveiled that students had positive attitude towards mathematics but at medium level, however, the level of female students was less than males. The regression models were fit in predicting the contribution of components of attitude towards mathematics scales on students’ achievement. In this regard, 42.8% (Grade 10) and 55.4% (Grade 12) of the variation in the achievement of students were jointly accounted for by the three variables – the enjoyment, the motivation, and the confidence attitude scales. In both grade levels, no significant gender differences were shown in attitudes towards mathematics but females showed greater decline in attitudes in terms of grade level. However, significant gender differences were specified on achievement. Attitude towards mathematics and students’ achievement were significantly correlated (r =.660; p <.001 (Grade 10) and r =. 735; p <. 001 (Grade 12)). Therefore, this study suggests that, the school, the teachers, parents, and concerned bodies have to intervene and design ways in order to enhance students’ attitude and performance in mathematics, in particular female students.
Credit Expansion and Banking Crises: The Role of Guarantees

This paper aims at analysing whether banking changes that occurred in Italy in the last fifteen years have mined the soundness of its financial system. We look for potential threats to financial stability as a result of the dynamic behaviour of Italian banks that progressively have been favouring consumer households at the expense of firms in the allocation of credit. The theme of financial instability is closely linked to the question of capital regulation, which is a centrepiece of government intervention because it affects banks’ soundness and risk taking incentives. After reviewing the literature on capital regulation, we first discuss the role of guarantees as a solution to banks’ potential instability in the case of credit default and, secondly, we estimate a bank interest rate model that explicitly includes collateral and personal guarantees as explanatory variables. We show that banks follow different lending policies according to the type of customer. In the case of firms banks seem to efficiently screen and monitor customers and guarantees (real and personal) are both used to reduce moral hazard problems. In the case of consumer households and sole proprietorships banks behave “lazily” by replacing screening and monitoring activities with personal guarantees; instead, collateral is used to separate good from bad customers (i.e., to mitigate adverse selection problems). These results, together with the large proportion of bad loans in case of unsecured loans, may indicate the existence of potential sources of financial instability because (a) personal guarantees are a small share of loans, especially in the case of consumer households, (b) a decline in the value of collateral held by banks in the event of a housing market weakening.

Conclusion: Oligohydramnios is a significant high-risk factor for adverse perinatal outcome and low AFI is a method of fetal surveillance.
Asymptotic Behavior of Colored Jones polynomial and Turaev-Viro Invariant of figure eight knot

In this paper we investigate the asymptotic behavior of the colored Jones polynomial and the Turaev-Viro invariant for the figure eight knot. More precisely, we consider the $M$-th colored Jones polynomial evaluated at $(N+1/2)$-th root of unity with a fixed limiting ratio, $s$, of $M$ and $(N+1/2)$. Generalizing the work of \cite{WA17} and \cite{HM13}, we obtain the asymptotic expansion formula (AEF) of the colored Jones polynomial of figure eight knot with $s$ close to $1$. An upper bound for the asymptotic expansion formula of the colored Jones polynomial of figure eight knot with $s$ close to $1/2$ is also obtained. From the result in \cite{DKY17}, the Turaev Viro invariant of figure eight knot can be expressed in terms of a sum of its colored Jones polynomials. Our results show that this sum is asymptotically equal to the sum of the terms with $s$ close to 1. As an application of the asymptotic behavior of the colored Jones polynomials, we obtain the asymptotic expansion formula for the Turaev-Viro invariant of the figure eight knot. Finally, we suggest a possible generalization of our approach so as to relate the AEF for the colored Jones polynomials and the AEF for the Turaev-Viro invariants for general hyperbolic knots.
ANGULAR MOMENTA, DYNAMICAL MASSES, AND MERGERS OF BRIGHTEST CLUSTER GALAXIES

Using the VIMOS integral field unit (IFU) spectrograph on the Very Large Telescope, we have spatially mapped the kinematic properties of 10 nearby brightest cluster galaxies (BCGs) and 4 BCG companion galaxies located within a redshift of z = 0.1. In the hierarchical formation model, these massive galaxies (1010.5 M☉ < Mdyn < 1011.9 M☉) are expected to undergo more mergers than lower mass galaxies, and simulations show that dry minor mergers can remove angular momentum. We test whether BCGs have low angular momenta by using the λRe parameter developed by the SAURON and ATLAS3D teams and combine our kinematics with Sloan Digital Sky Survey photometry to analyze the BCGs' merger status. We find that 30% (3/10) of the BCGs and 100% of the companion galaxies (4/4) are fast rotators as defined by the ATLAS3D criteria. Our fastest rotating BCG has a λRe = 0.35 ± 0.05. We increase the number of BCGs analyzed from 1 in the combined SAURON and ATLAS3D surveys to 11 BCGs total and find that above Mdyn ∼ 11.5 M☉, virtually all galaxies, regardless of environment, are slow rotators. To search for signs of recent merging, we analyze the photometry of each system and use the G − M20 selection criteria to identify mergers. We find that 40% ± 20% of our BCGs are currently undergoing or have recently undergone a merger (within 0.2 Gyr). Surprisingly, we find no correlation between galaxies with high angular momentum and morphological signatures of merging.
