Material-element deformation in isotropic turbulence

The evolution of infinitesimal material line and surface elements in homogeneous isotropic turbulence is studied using velocity-gradient data generated by direct numerical simulations (DNS). The mean growth rates of length ratio (l) and area ratio (A) of material elements are much smaller than previously estimated by Batchelor (1952) owing to the effects of vorticity and of non-persistent straining. The probability density functions (p.d.f.'s) of l/〈l〉 and A/〈A〉 do not attain stationarity as hypothesized by Batchelor (1952). It is shown analytically that the random variable l/〈l〉 cannot be stationary if the variance and integral timescale of the strain rate along a material line are non-zero and DNS data confirm that this is indeed the case. The application of the central limit theorem to the material element evolution equations suggests that the standardized variables $\hat{l}(\equiv (\ln l - \langle \ln l\rangle)/({\rm var} l)^{\frac{1}{2}})$ and Â(≡(ln A − 〈ln A〉)/(var A)½) should attain stationary distributions that are Gaussian for all Reynolds numbers. The p.d. f.s of $\hat{l}$ and Â calculated from DNS data appear to attain stationary shapes that are independent of Reynolds number. The stationary values of the flatness factor and super-skewness of both $\hat{l}$ and Â are in close agreement with those of a Gaussian distribution. Moreover, the mean and variance of ln l (and ln A) grow linearly in time (normalized by the Kolmogorov timescale, τη), at rates that are nearly independent of Reynolds number. The statistics of material volume-element deformation are also studied and are found to be nearly independent of Reynolds number. An initially spherical infinitesimal volume of fluid deforms into an ellipsoid. It is found that the largest and the smallest of the principal axes grow and shrink respectively, exponentially in time at comparable rates. Consequently, to conserve volume, the intermediate principal axis remains approximately constant. The performance of the stochastic model of Girimaji & Pope (1990) for the velocity gradients is also studied. The model estimates of the growth rates of 〈ln l〉 and 〈ln A〉 are close to the DNS values. The growth rate of the variances are estimated by the model to within 17%. The stationary distributions of $\hat{l}$ and Â obtained from the model agree very well with those calculated from DNS data. The model also performs well in calculating the statistics of material volume-element deformation.
Pattern of psychoactive substance use among university students in South-Western Nigeria

Psychoactive substance use is a major public health issue globally. Studies worldwide suggest that the prevalence of substance use among undergraduates may be on the rise. This study aimed at determining the prevalence, pattern and associated factors of substance use among students in a university in Southwestern Nigeria. The WHO Student Drug Use questionnaire was used to assess for drug use among final year students, while psychological distress was evaluated with GHQ 12. Lifetime prevalence of any psychoactive substance use was 78%. The prevalence of alcohol, cannabis and inhalant was significantly more in males. The prevalence of alcohol use was significantly lower among students who reported frequent participation in religious activities. There was a significant relationship between tobacco, cannabis use and psychological distress. The prevalence of psychoactive substance is high among university students. There is urgent need for adequate screening, assessment and treatment of substance use disorder amongst these students.

Thyroid Hormone and Blood Metabolites Concentrations of Broiler Chickens Subjected to Feeding Time Restriction

The present study was conducted to determine the effect of feeding time restriction on thyroid hormone and blood metabolites concentration of broiler chickens during feed restriction and realimentation period. Four hundred of 7 days-old unsexed broiler chicken of Lohmann commercial strain were arranged in a completely randomized design with 5 treatments and analyzed based on ANOVA. The treatments were: chicks fed ad libitum as a control treatment (R-0); chicks had free access to feed during two periods of 2 h (08:00-10:00 and 16:00-18:00) from 7-14 d of age (R-1) and 7-21 d of age (R-2); chicks had free access to feed during two periods of 4 h (08:00-12:00 and 16:00-20:00) from 7-14 d of age (R-3) and 7-21 d of age (R-4). The treatments consisted of 4 replicates with 20 chicks each. During feeding time restriction from 7 to 21 d of age, thyroid hormone and albumin plasma concentration of R-2 and R-4 were lower (P<0.05) than R-0. There were no statistical differences among the treatments on thyroid hormone and blood metabolites during realimentation period from 21 to 42 d of age. It is concluded that thyroid hormone triiodothrionine and thyroxine (T3 and T4) and blood metabolite (albumin) decreased during feeding time restriction for 4 and 8 h per d from 7 to 21 d of age and it returns to normal during realimentation period.
BIOREMEDIATION OF CADMIUM(II) FROM AQUEOUS SOLUTION USING AGRICULTURAL WASTE: ZEA MAIZE LEAVES

In the present study, agricultural waste Zea maize leaves powder (MLP) was used for the removal of cadmium (II) from the aqueous solutions. The adsorption characteristics of maize leaf as a function of pH (2-7), adsorbent dose (0.2-0.5 g), temperature (20-30C), contact time (0-120 min) and initial metal concentration (1-15 mg L) were studied. The biosorption of cadmium (II) on MLP was dependent on pH, adsorbent dose, temperature, contact time and initial metal concentration . The experimental results were analyzed in terms of Langmuir and Freundlich isotherm models. The Fourier Transform Infrared (FTIR) measurements reveal that the presence of hydroxyl, amino and carboxylic functional groups on the surface of MLP which provide the major biosorption sites for the metal binding. The results obtained could be useful for the application of agricultural wastes for heavy metal removal from the industrial waste water.
Does Fiscal Decentralization Increase the Investment Rate? Evidence from Chinese Dynamic Panel Data

China has one of the highest investment rates in the world, and in 1994, China introduced a new fiscal system. The current study utilizes provincial panel data from the period of 1995-2010 to provide a consistent underlying fiscal regime. The estimation results show that expenditure decentralization has a significant, positive effect on the physical capital investment rate in both least squares dummy variables (LSDV) and system GMM (Generalized method of moments) estimations. In contrast, revenue decentralization has a negative effect on the investment rate. One possible explanation is that China's political centralization has been maintained during its economic decentralization. Since the provincial officials are not elected by local constituents but are rather appointed by the central government, it is rational for provincial officials to raise investment rates to meet the cadre promotion criteria of the central government, be it growth performance, as argued by Blanchard and Shleifer (2001) or revenue collection, identified by Shih et al. (2012).
Effect of correlations and doping on the spin susceptibility of iron pnictides: the case of KFe2As2

The temperature dependence of the paramagnetic susceptibility of the iron pnictide superconductor KFe2As2 and its connection with the spectral properties of that material is investigated by a combination of density functional theory (DFT) in the local density approximation and dynamical mean-field theory (DMFT). Unlike other iron pnictide parent compounds where the typical oxidation state of iron is 2, the formal valence of Fe in KFe2As2 is 2.5, corresponding to an effective doping with 0.5 hole per iron atom compared to, for example, BaFe2As2. This shifts the chemical potential and thereby reduces the distance between the peaks in the spectral functions of KFe2As2 and the Fermi energy as compared to BaFe2As2. The shift, which is clearly seen on the level of DFT as well as in DMFT, is further enhanced by the strong electronic correlations in KFe2As2. In BaFe2As2 the presence of these peaks results (Phys. Rev. B 86, 125124 (2012)) in a temperature increase in the susceptibility up to a maximum at ∼1000 K. While the temperature increase was observed experimentally the decrease at even higher temperatures is outside the range of experimental observability. We show that in KFe2As2 the situation is different. Namely, the reduction of the distance between the peaks and the Fermi level due to doping shifts the maximum in the susceptibility to much lower temperatures, such that the decrease in the susceptibility becomes visible in experiment.
High-Frequency Wage Rigidity

In the context of a frictional model of the labor market with o¤ and on the job search, I advance a novel model of wage determination where contracts are non-binding and rms have private information about the productivity of labor. The characterization of the intra rm bargaining game leads to a reduced-form model where the rm chooses the wage subject to a non-discrimination and consistency constraints. The fundamental property of the optimal rm-wage policy is high-frequency wage rigidity. While the rm does not respond to productivity shocks whose persistence falls below a critical threshold, the wage is a nondegenerate function of the long-term component of labor productivity. A calibrated version of the model shows that the cyclical behavior of the model is quantitatively consistent with the empirical regularities of the labor market at the business cycle frequency. Among other things, wages are nearly acyclical, the semi-elasticity of the average labor productivity to unemployment is smaller than one, and vacancies are almost perfectly correlated with unemployment.
Dynamo Theory, Nonlinear Magnetic Fields, and the Euler Potentials

The debate on the role of Euler potentials (EP), α∇β, in the dynamo theory is a long-standing one. It is known that the cross-product of gradients of two the potentials may represent magnetic fields lines. However, 2D and 3D dynamo hydromagnetic simulations suggest that their utility as analogues of magnetic field potential is restricted. This raises questions about their utility in the broader context of magneto-genesis and dynamo theories. We reexamine this and find that a reinterpretation of such potentials offers a new insight into the role EP may play in the general evolution of magnetic fields.
ATF 6 beta is a host cellular target of the Toxoplasma gondii virulence factor ROP 18 YAMAMOTO

The ROP18 kinase has been identified as a key virulence determinant conferring a high mortality phenotype characteristic of type I Toxoplasma gondii strains. This major effector molecule is secreted by the rhoptries into the host cells during invasion; however, the molecular mechanisms by which this kinase exerts its pathogenic action remain poorly understood. In this study, we show that ROP18 targets the host endoplasmic reticulum-bound transcription factor ATF6β. Disruption of the ROP18 gene severely impairs acute toxoplasmosis by the type I RH strain. Because another virulence factor ROP16 kinase modulates immune responses through its N-terminal portion, we focus on the role of the N terminus of ROP18 in the subversion of host cellular functions. The N-terminal extension of ROP18 contributes to ATF6β-dependent pathogenicity by interacting with ATF6β and destabilizing it. The kinase activity of ROP18 is essential for proteasome-dependent degradation of ATF6β and for parasite virulence. Consistent with a key role for ATF6β in resistance against this intracellular pathogen, ATF6β-deficient mice exhibit a high [. ] YAMAMOTO, Masahiro, et al.

Chapter C 3 : The Maintenance of Soil Fertility in Amazonian Managed Systems

Most of Brazilian Amazonia faces important limitations for conventional agriculture and pastures due to a generally poor chemical fertility as well as the region’s environmental conditions, especially high temperature and moisture. Without proper management, degradation of the soil and resulting unsustainability of agricultural and ranching production occur within a few years, leading to land abandonment. Use of perennial crops, especially those based on native tree species, would be instrumental in order to achieve best management such as that which assure recycling processes similar to those in the primary forest. Recommended alternative land uses are those producing high soil organic matter, recycling of nutrients, substantial agricultural production and economic viability. These include agroforestry systems, enrichment of second growth with valuable native timber or fruit species, accelerated fallow regrowth via enrichment plantings, sequential agroforestry with slash-and-mulch, and diversified forest plantations. Improvement of agricultural soils can be based on lessons learned from the study of processes involved in the formation and maintenance of the rich “dark earths” (terra preta), which owe their high carbon content and fertility in part to high content of charcoal. Adding powdered charcoal combined with selected nutrients can increase soil carbon in modern agriculture. Considering that limitations to expansion of intensified land uses in Amazonia are serious, regional development should emphasize the natural forest, which can maintain itself without external inputs of nutrients. Instead of creating conditions to further expand deforestation, these forests may be used as they stand to provide a variety of valuable environmental services that could offer a sustainable basis for development of Amazonia.
The Life-cycle Impact of Alternative Higher Education Finance Systems in Ireland

With increasing numbers of young people participating in higher education in Ireland and a heavy reliance of higher education institutions on State funding, the introduction of an alternative finance system for Ireland has been muted over the past number of years. However, no study has been conducted to gauge the potential impact of such measures. In this paper we utilise a dynamic microsimulation model developed for Ireland to simulate the impact of both an income contingent loan system (ICL) and a graduate tax system from a fiscal and redistributional viewpoint and to analyse the repayment length under the former system. Our results suggest that an ICL system could be more equitable, while the graduate tax system could be a better alternative from a fiscal viewpoint. The results also illustrate the importance of the interest rate attached to any future student loan system within Ireland from a fiscal viewpoint
Systematics of the Anoa (Mammalia, Bovidae)

The systematic position of the Anoa is discussed, with reference to its nomenclature and taxonomic history. Two distinct types of Anoa are found all over Celebes, a large one with white legs, long tail and rugged horns, and a small one with legs mainly the same colour as the body, short tail and conical horns. There is some indication that the small Anoa inhabits mountainous areas. In the absence of any evidence of intergradation they must be classed as two distinct species; since the Anoa is closely related to the Indian Buffalo and the Tamarao, the two must be called Bubalus (Anoa) depressicornis and B. (A.) quarlesi.
Perceived importance and manageability of teachers toward the factors of integrating computer technology into classrooms

In this study, the perceived importance and manageability of teachers on the factors in technology integration were assessed among 407 elementary and secondary schoolteachers. A questionnaire containing 28 items focusing on environmental, personal, social and curricular factors related to technology integration was used. Two sets of data resources gathered from the questionnaire for obtaining teachers’ responses toward the factors of integrating technology into classrooms include: (1) the importance rating for each factor, and (2) the manageability of each item. Factor analysis was first conducted to test the reliability of the questionnaire. From the analysis, four items were dropped and 24 items were selected and regrouped. Cramer’s V analyses among the selected 24 items revealed that teachers’ perceived importance ratings were related with their manageability in some of the factors for integrating computers into classrooms. Relationships between teachers’ use of computers and their perceived importance among the four main factors were also reported.
Effects of the aqueous extract of fresh leaves of Calotropis procera on haematological and biochemical parameters in female rabbits

Calotropis procera has been reported to be medicinal and toxic in animals. A toxicological evaluation of the aqueous extract of its fresh leaves was conducted in female rabbits (Oryctolagus cuniculus). Low levels of phytochemicals (alkaloids, saponins, tannins, cardiac glycosides, and flavonoids) were found while 0.23, 0.03, 0.82 and 9.5 mg/g of iron, lead, sodium and potassium, respectively, were detected. Acute toxicity study was conducted with oral administration of 200, 400, 800 and 1600 mg/kg of the extract once to groups I, II, III and IV, respectively. Four rabbits died within 24 h and LD50 was estimated (940 mg/kg). 80, 40 and 20 mg/kg of the extract were administered daily to groups I, II, and III, respectively, during sub-acute toxicity study for 14 days. All controls were given water. Statistical analysis of aspartate amino transferase (AST), alanine amino transferase (ALT), alkaline phosphatase (ALP), albumin and protein showed no significant changes at P eosinophils, heterophils/neutrophils and basophils) were equally statistically not significant at P orally at tolerable doses since the values were in the range of control values.
Optimum size in grid soil sampling for variable rate application in site-specific management

The importance of understanding spatial variability of soils is connected to crop management planning. This understanding makes it possible to treat soil not as a uniform, but a variable entity, and it enables site-specific management to increase production efficiency, which is the target of precision agriculture. Questions remain as the optimum soil sampling interval needed to make site-specific fertilizer recommendations in Brazil. The objectives of this study were: i) to evaluate the spatial variability of the main attributes that influence fertilization recommendations, using georeferenced soil samples arranged in grid patterns of different resolutions; ii) to compare the spatial maps generated with those obtained with the standard sampling of 1 sample ha -1 , in order to verify the appropriateness of the spatial resolution. The attributes evaluated were phosphorus (P), potassium (K), organic matter (OM), base saturation (V%) and clay. Soil samples were collected in a 100 × 100 m georeferenced grid. Thinning was performed in order to create a grid with one sample every 2.07, 2.88, 3.75 and 7.20 ha. Geostatistical techniques, such as semivariogram and interpolation using kriging, were used to analyze the attributes at the different grid resolutions. This analysis was performed with the Vesper software package. The maps created by this method were compared using the kappa statistics. Additionally, correlation graphs were drawn by plotting the observed values against the estimated values using cross-validation. P, K and V%, a finer sampling resolution than the one using 1 sample ha -1 is required, while for OM and clay coarser resolutions of one sample every two and three hectares, respectively, may be acceptable.
