Determination of Heavy Metals in Fish (Clarias gariepinus) Organs from Asaba Major Markets, Delta State, Nigeria

In this study selected heavy metals- zinc, lead, cadmium, copper, mercury and cobalt in organs of clarias - gariepinus sold in three major markets in Asaba, Delta State, Nigeria were determined by atomic absorption spectrophotometry, and their bioaccumulation compared. The result revealed that the gills contained the highest total concentration (11.363 ppm) representing 27.70% of the detected heavy metals; followed by the liver (11.267 ppm) representing 27.46%; followed by the heart (10.303 ppm) representing 25.11% while the muscle had the lowest concentration (8.095) representing 19.73%. The difference in the bioaccumulation in the various organs however , did not differ significantly (P = 0.990). The overall accumulation pattern for the three markets was: Ogbeogonogo - Zn > Hg > Cu >Pb> Cd > Co; Cable - Zn > Cu >Hg >Pb> Co > Cd; and Abraka - Zn > Cu > Hg > Cd > Co >Pb. Zn mean concentration differs significantly (P =.000) from those of other metals. Mean concentrations of Pb, Cd, and Co were significantly the same but differ from those of Cu and Hg whose mean concentrations were statistically the same. The total concentrations in ppm of Zn (35.995, 32.336, and 36.292); Cu (1.587, 4.189, and 3.496) and Co (0.016, 0.070, and 0.088) in the three markets were below the permissible limits of 150 ppm, 10 ppm, and 0.15 – 1.0 ppm respectively stipulated by FAO/WHO. Also, the concentrations of Pb, 0.139 in Cable and 0.000 in Abraka; and Cd, 0.042 in Ogbeogonogo and 0.031 in Cable were below the permissible limits 0.5 ppm for Pb and 0.05 ppm for Cd. However, the concentrations in ppm of Pb, 0.949 in Ogbeogonogo, Cd, 0.673 in Abraka, and Hg in all three markets were above the permissible limits of 0.5 ppm, 0.05 ppm and 0.5 ppm in fish and food substances. The consumption of Clarias - gariepinus sold in these markets poses serious health threat to humans especially pregnant women. Keywords : Heavy metals, Clarias- gariepinus , organs, bioaccumulation, digestion, permissible limit.
International Experience With Uniform Accounting

Seen internationally, the desire to achieve greater uniformity in accounting has been with us for a long time. In the early I92os, the German Professor Eugen Schmalenbach was frustrated again and again by the failure of his own efforts and those of his students to compare meaningfully the financial data made available by different companies. This led to concentrated research on the problem and resulted in the publication of a book by Schmalenbach entitled The Model Chart of Accounts.l With this book Schmalenbach laid the foundation for all subsequent developments in uniform accounting in Germany. It also became the basis for corresponding efforts in other European countries.2 Thus Schmalenbach is without doubt the intellectual father of organized thought on behalf of uniform accounting. Prior to these German academic endeavors, many procedural schemes had come into existence with the purpose of unifying and standardizing bookkeeping methods. Trade associations and industrial branch groups spearheaded this activity. For example, a uniform accounting system was developed by the British Federation of Master Printers and put into satisfactory operation by I9I9.3 In the United States, the American Water Works Association compiled a uniform chart of accounts in I9IO and urged its use by its members.4 Other similar references abound. Lengyel quotes a I930 resolution adopted at the sixteenth annual meeting of the Chamber of Commerce of the United States:
Synthesis of Well-Defined Three-Arm Star-Branched Polystyrene through Arm-First Coupling Approach by Atom Transfer Radical Polymerization

Here we describe a simple route to synthesize three-arm star-branched polystyrene. Atom transfer radical polymerization technique has been utilized to yield branched polystyrene involving Williamson coupling strategy. Initially a linear polymeric chain of predetermined molecular weight has been synthesized which is further end-functionalized into a primary alkyl bromide moiety, a prime requisition for Williamson reaction. The end-functionalized polymer is then coupled using 1,1,1-tris(4-hydroxyphenyl)ethane, a trifunctional core molecule, to give well-defined triple-arm star-branched polystyrene.
How mRNA transport in nerve cells influences synapses and learning

mRNA localization, a widespread and highly conserved mechanism, is essential for the spatial and temporal control of protein expression in various cell types. It allows mammalian nerve cells to respond rapidly to local protein requirements in their long processes, e.g. in growth cones during axon outgrowth. Recent studies provided a first insight into the mechanisms of mRNA transport in neurons and how local translation modulates individual synapses in the central nervous system during learning processes. Failure of proper mRNA localization in neurons can lead to severe diseases in humans.
An Information Theoretic Formulation of Game Theory, II

This short article follows an earlier document, wherein I indicated how the foundations of game theory could be reformulated within the lens of a more information theoretic and topological approach. Building on said work, herein I intend to generalise this to meta games, where one game (the meta-game) is built on top of a game, and then to meta-meta-games. Finally I indicate how one might take these ideas further, in terms of constructing frameworks to study policies, which relate to the solution of various algebraic invariants.
SIFT Saliency Analysis for Matching Repetitive Structures

The ambiguity resulting from repetitive structures in a scene presents a major challenge for image matching. This paper proposes a matching method based on SIFT feature saliency analysis to achieve robust feature matching between images with repetitive structures. The feature saliency within the reference image is estimated by analyzing feature stability and dissimilarity via Monte-Carlo simulation. In the proposed method, feature matching is performed only within the region of interest to reduce the ambiguity caused by repetitive structures. The experimental results demonstrate the efficiency and robustness of the proposed method, especially in the presence of respective structures.
Crystal and electronic structure of the room temperature organometallic ferrimagnet V(TCNE)2. Analysis of numerical DoS and magnetic properties as related to orbital and spin‐Hamiltonian models

We present a detailed analysis of the results of our numerical study of the crystal and electronic structure of the room temperature organometallic ferrimagnet of general composition V(TCNE)x with x ≈ 2. The results of the LSDA +U study show that the experimentally determined structure complies with the magnetic measurements and thus can serve as a prototype structure for the entire family of the M(TCNE)2 organometallic magnets. The results of the numerical study and of the magnetic experiments are interpreted using a spin-wave treatment of the model Hamiltonians proposed here. This allowed us to obtain estimates of the critical temperature in three- and two-dimensional regimes and to give an explanation of the differences in behavior of probably isostructural V(TCNE)2 and Fe(TCNE)2 species. © 2010 Wiley Periodicals, Inc.

Resultados: Los valores encontrados para el trabajo y la potencia maxima en la extension de rodillas corroboran con los reportados en la literatura. Un alto ICC para ambas variables fue encontrado (97% y 93%, respectivamente) y un bajo EPM (2,09% y 10,13%, respectivamente). Conclusion: Se demostro un metodo economico para evaluar el indicador primario de la disfuncion fisica en los ancianos, que puede ser utilizado tanto para el monitoreo de la disfuncion como para la intervencion.
Measure research to improve the teaching effect of Food Standard and Regulation Course

The curricular features of food standard and regulation were analyzed in this paper and the measures of improving teaching effect were proposed based on current food safety situation. These measures included elaborate choice of teaching contents, statement with the recent case, emphasis of the inherent relationship of knowledge, enhancement of the classroom interaction and increasing students' interest through practice. After the implementation of provided measures, classroom atmosphere was enlivened, learning interest was increased, and students effectively mastered the knowledge of food standard and regulation. Moreover, student application ability was enhanced. Those measures might create a good win-win situation among college, student, and employer in current job market full of fierce competition.
Performance of the Double Absorbing Boundary Method when Applied to the 3D Acoustic Wave Equation

The double absorbing boundary (DAB) is a new high-order absorbing boundary condition for the scalar acoustic wave equation. It suppresses scattered waves at the edge of a boundary layer in computational domain boundary by using destructive interference analogous to a noise-cancelling headphone. This method has advantages in that it addresses some of the shortfalls in existing boundary conditions, such as the need for tuning in Perfectly Matched Layers or complex formulations at corners such as in high-order absorbing boundary conditions. We extend the original formulation of the DAB to three dimensions and higher-order stencils. Through numerical simulation we test the performance of the DAB by comparison with a reflecting boundary. We find that the DABC is a broadband attenuator with a power attenuation of 20-30dB using only six boundary cells. Increasing the order of the method improves accuracy for wavelengths less than 10 cells, whereas increasing the layer width does not improve accuracy. The method shows promise as a robust and computationally efficient boundary condition for seismic applications.
The Psychological Contract: A Critical Review

Literature on the psychological contract has blossomed progressively over the last ten years to the extent that it is now firmly located within the lexicon of the Human Resource Management (HRM) discipline. Yet as this review indicates, the theoretical assumptions that seem to pervade the psychological contract literature are not without major deficiencies, which in turn pose serious questions around the continued sustainability of the construct as currently constituted. This paper addresses some of the central problems presently confronting the theoretical side of the psychological contract literature. In seeking to advance knowledge and understanding, this review calls for an alternative approach to studying the psychological contract on the basis of a more critical and discursive literature analysis. From this, the authors unpick the construct of the psychological contract as portrayed in much of the extant literature and argue that, in its present form, it symbolizes an ideologically biased formula designed for a particular managerialist interpretation of contemporary work and employment.
On the Control of a One Degree-of-Freedom Juggling Robot

This paper is devoted to the feedback control of a one degree-of-freedom (dof) juggling robot, considered as a subclass of mechanical systems subject to a unilateral constraint. The proposed approach takes into account the whole dynamics of the system, and focuses on the design of a force input. It consists of a family of hybrid feedback control laws, that allow to stabilize the object around some desired (periodic or not) trajectory. The closed-loop behavior in presence of various disturbances is studied. Despite good robustness properties, the importance of good knowledge of the system parameters, like the restitution coefficient, is highlighted. Besides its theoretical interest concerning the control of a class of mechanical systems subject to unilateral constraints, this study has potential applications in non-prehensile manipulation, extending pushing robotic tasks to striking-and-pushing tasks.

If leader can show the attitude and behavior which accordance to the employee needs, then the good relations will emerge and it will influence the performance.
Irrationality of Fast Converging Series of Rational Numbers

We say that the series of general term un � 0 is fast converging if log |un |≤ c2 n for some c< 0. We prove irrationality results and compute irrationality measures for some fast converging se- ries of rational numbers, by using Mahler's transcendence method in the form introduced by Loxton and Van der Poorten. With very weak assumptions on sequence un, this method allows to obtain only irra- tionality results.
Existence and multiplicity of solutions for a Robin problem

In this article we study the nonlinear Robin boundary-value problem −Δp(x)u = λf(x, u), in Ω ; |∇u| ∂u ∂ν + β(x)|u|u = 0, on ∂Ω. Using the variational method, under appropriate assumptions on f, we obtain a result on existence and multiplicity of solutions.
Adoption of Internet-enabled Supply Chain Integration: Institutional and Cultural Perspectives

Fostering supply chain integration (SCI) via Internet technologies has been widely regarded as a critical factor for firm success. Internet-enabled SCI may help enhance firms’ capabilities in technology, product and market development, and thus allows firms to initiate or adapt to com-petitive changes in the market. Yet, the decision on Internet-enabled SCI is challenging due to the high uncertainties involved. Research on the antecedents of Internet-enabled SCI is of in-terest to both researchers and practitioners. Based on the view of upper echelons theory (UET), this research derives a syncretic model for firms’ adoption of Internet-enabled SCI by presenting senior executives’ cognitions as firms’ perceived institutional pressures, and senior executives’ values as firms’ organizational culture. Results from a survey show that institutional pressures and a culture that values organic process have a strong impact on firms' inclination toward In-ternet-enabled SCI. In addition, we find that institutional pressures and organizational culture have interaction effects on Internet-enabled SCI.
Music Therapy Methods and Vocalizations: A Look into One Boy's Process

This capstone thesis project explores a detail-oriented music therapy approach used to elicit vocalizations and speech for an individual on the autism spectrum. Although there is compelling research on music therapy contributing to speech acquisition for individuals with autism spectrum disorder (ASD), the methods discussed in the literature are vague and do not discuss the music itself in detail. Specifics would be helpful in order to allow these methods to be replicable. To explore specific musical elements, I administered five 30-minute music therapy sessions to a 12-year-old boy on the autism spectrum during his school day. During sessions, I measured vocalizations and intelligible speech within three distinct interventions: preferred song choices, vocal exercises, and client-led improvisation. Client-led improvisation produced not only the most overall vocalizations, but also the most intelligible words spoken by the client in comparison to the other categories studied. This thesis concludes with a discussion of how this method compares to the use of client-preferred songs and further applications for this intervention method and path of inquiry.
Reproductive biology of free-living and commensal polynoid polychaetes at the Lucky Strike hydrothermal vent field (Mid-Atlantic Ridge)

We examined the reproductive biology of a polynoid polychaete commensal in mussel mantle cavities (Branchipolynoe cf. seepensis) and of a polynoid polychaete that is free-living among those same mussels (Opisthotrochopodus n. sp.). Specimens of each species were collected from 2 different sites (Eiffel Tower and Sintra; ∼400 m apart) within the Lucky Strike hydrothermal field. Both species exhibit sexual dimorphism, with varying numbers of pairs of nephridial papillae. In B. cf. seepensis, sexual dimorphism also includes a difference in size, with females larger than males. Contrary to our expectations, the reproductive biology of both species is very similar. Sperm heads are elongate, suggesting some mode of sperm transfer or storage. Females of both species contain mature sperm and there is evidence of internal fertilization. Maximum oocyte diameters are large (>390 μm), from which we infer non-planktotrophic development; oogenesis is intraovarian and suggests rapid oocyte development. Oocyte size-frequency distributions and population size structure suggest a pattern of asynchronous gametogenesis. We found no substantive evidence for site-specific variations in reproductive biology in either species.
Income Mobility in the United States: New Evidence from Income Tax Data

While many studies have documented the long-term trend of increasing income inequality in the U.S. economy, there has been less focus on income mobility and the potential opportunity for upward mobility. Data from panels of individual income tax returns suggest that there was considerable income mobility in the U.S. economy over the 1987-1996 and 1996-2005 periods. Consistent with prior mobility studies, the data show that over half of taxpayers moved to a different income quintile and that roughly half of taxpayers who began in the bottom income quintile moved up to a higher income group by the end of each period. By contrast, those with the very highest incomes in the base year were more likely to drop to a lower income group and the median real income of these taxpayers declined in each period. Economic growth resulted in rising incomes for most taxpayers over both time periods. Initial position in the income distribution and changes in marital status were found to be associated with the largest upward or downward movements through the income distribution.
An Enhanced Power Based MAC Protocol for Wireless Networks

Power based connectivity is an ad hoc research topic. Implementing power control mechanisms enhance network life and to improve throughput, locate cost effective routes and spatial reuse. This paper uses MAC protocol to implement coordination functions and power control mechanisms through the use of fuzzy rules generated by upper network layers using two input variables like link quality and node neighborhood count with optimal power consumption level as the output variable. Experiments using fuzzy rules are compared to DSR routing and two hop power control methods. Result showed that two hop power control with fuzzy logic method yields lower route discovery time, increased cache replies, minimum simulation time and end to end delay when compared to DSR routing and two hop routing protocol.
On the origin of moisture related to synoptic-scale rainfall events for the North American Monsoon System

Abstract. This work examines the origin of atmospheric water vapor arriving to the North American Monsoon (NAM) region over a 34-yr period (1981–2014) by using a Lagrangian diagnosis method. This methodology computes budgets of evaporation minus precipitation by calculating changes in the specific humidity of thousands of air particles advected into the study area by the observed winds. During the NAM wet season, on average the recycling process is the main water vapor source, followed by the supply of moisture from the Gulf of California. However, the water vapor transport that generates synoptic-scale rainfall comes primarily from the Caribbean Sea, the Gulf of Mexico and terrestrial eastern Mexico. An additional moisture source over the southwestern US is also identified in association with synoptic rainfall events over the NAM region. A high (low) moisture supply from the Caribbean Sea and the Gulf of Mexico from 4 to 6 days before precipitation events is responsible for high (low) rainfall intensity on synoptic scales during the monsoon peak. Westward propagating mid to upper level inverted troughs (IVs) seem to favor these water vapor fluxes. A 200 % increase in the moisture flux from the Caribbean Sea is related to the occurrence of heavy precipitation in the NAM area, accompanied by a decrease in water vapor advection from the Gulf of California.
SDSS-IV MaNGA: Modelling the Metallicity Gradients of Gas and Stars – Radially Dependent Metal Outflow Versus IMF

In our previous work, we found that only two scenarios are capable of reproducing the observed integrated mass–metallicity relations for the gas and stellar components of local star-forming galaxies simultaneously. One scenario invokes a time-dependent metal outflow loading factor with stronger outflows at early times. The other scenario uses a time-dependent initial mass function (IMF) slope with a steeper IMF at early times. In this work, we extend our study to investigate the radial profile of gas and stellar metallicity in local star-forming galaxies using spatially resolved spectroscopic data from the SDSS-IV MaNGA survey. We find that most galaxies show negative gradients in both gas and stellar metallicity with steeper gradients in stellar metallicity. The stellar metallicity gradients tend to be mass dependent with steeper gradients in more massive galaxies while no clear mass dependence is found for the gas metallicity gradient. Then we compare the observations with the predictions from a chemical evolution model of the radial profiles of gas and stellar metallicities. We confirm that the two scenarios proposed in our previous work are also required to explain the metallicity gradients. Based on these two scenarios, we successfully reproduce the radial profiles of gas metallicity, stellar metallicity, stellar mass surface density, and star formation rate surface density simultaneously. The origin of the negative gradient in stellar metallicity turns out to be driven by either radially dependent metal outflow or IMF slope. In contrast, the radial dependence of the gas metallicity is less constrained because of the degeneracy in model parameters.
