ORIGINAL ARTICLE Cerebrospinal fluid and serum zinc, copper, magnesium and calcium levels in children with Idiopathic seizure

Objectives: The present study was conducted to observe the alteration and their relations in cerebrospinal fluid (CSF) and serum Zinc (Zn), Copper (Cu), Magnesium (Mg) and calcium (Ca) levels in patients with different types of idiopathic seizure and to determine the ratios of serum and CSF Ca/Mg and Cu/Zn. Methods: The children aged 1 to 14 years, having two or more unprovoked seizures, which were detected by normal MRI scan and abnormal EEG were included in the study group. The control group consisted of 40 healthy children without seizure. Zn, Mg and Cu levels in CSF and serum were analyzed by an atomic absorption spectrophotometer. Results: The study subjects included 34 generalized seizures (GS), 5 cases of simple partial seizure (SPS) and 5 Complex partial seizures (CPS). Serum copper (Cu) was significantly elevated (P-0.01) in children with seizures. Within the seizure group, serum Mg was significantly increased in GS and serum copper (Cu) levels were significantly increased in CPS and GS as compared to controls (p-0.001). However, calcium and zinc levels did not show any significant change in all groups. CSF Calcium was significantly increased in CPS patients. The ratio obtained for the levels of these parameters revealed a significant increase in serum Cu/Zn ratio (P-0.002) and CSF Ca/Mg (P-0.04) in patients with idiopathic seizure as compared to controls. This ratio was also significant between SPS versus CPS and CPS versus GS. Conclusion: The findings of the present study suggest that high serum Cu and the increased ratio of serum Cu/Zn and CSF Ca/ Mg may be responsible for enhanced neuronal excitability in children with idiopathic seizures.
Effect of an Interactive Surface on the Equilibrium Contact Angles in Bilayer Polymer Films

Scanning transmission X-ray microscopy (STXM), atomic force microscopy (AFM), near-edge X-ray absorption fine structure (NEXAFS) spectroscopy, and photoemission electron microscopy (PEEM) were used to obtain the three-dimensional concentration profiles and the late-stage morphology of liquid bilayer thin films of the two imiscible polymers polystyrene (PS) and (polybromostyrene) (PBrx=0.79S), where x = fraction of monomers brominated) as a function of the lower PS film thickness. The results showed that the apparent contact angle at the polymer/air interface decreases exponentially with increasing PS film thickness with a constant that scales with the PS radius of gyration (Rg). In contrast, the Neuman angle, as determined from the PBrS STXM images, increases with substrate thickness. NEXAFS and PEEM data show that the droplets consist of a PBrS core fully encapsulated by PS for substrate thicknesses greater than Rg. Only partial encapsulation is seen for substrates less than Rg. These results could not b.
Qualidade física de Latossolo Amarelo de tabuleiros costeiros em diferentes sistemas de manejo da cana-de-açúcar

The physical attributes are important indicators to evaluate management systems. The objective of this research was to study alterations in the soil properties of the distrophic cohesive yellow Oxisol of a coastal plain in Alagoas state, Brazil, cultivated with sugarcane. Plots were selected in the following sugarcane-growing areas: area under irrigation management system (IMS), area fertigated with vinasse (FV), and area under application of vinasse + filter cake (V + FC). These management systems were compared to each other and to a control (native forest). The bulk soil density, total porosity, weighted mean diameter of the aggregates, hydraulic conductivity, total organic carbon and compaction degree were evaluated in 0-0.20; 0.20-0.40 e 0.40-0.60 m depths. The results showed that management system that receives residues of the sugarcane presents alterations in the physical properties of soil more adequate for development of sugarcane. Among the evaluated systems, little physical degradation was observed in area with application of vinasse + filter cake followed by area with application of vinasse.
Protein Adsorption on Alkanethiolate Self-assembled Monolayers: Nanoscale Surface Structural and Chemical Effects

We report a study of protein adsorption on controlled surfaces. Hydrophilic (carboxylic acid-terminated) and hydrophobic (methyl-terminated) self-assembled monolayers (SAMs) on Au(111) surfaces were prepared at different solution temperatures and characterized by low-current scanning tunneling microscopy (STM). Protein adsorption on these SAMs was investigated by surface plasmon resonance (SPR) sensors and tapping-mode atomic force microscopy (TM-AFM). Results show that both nanoscale surface chemical and structural properties of SAMs affect protein adsorption. Specifically, carboxylic acid-terminated SAMs formed at higher temperatures have more compact structures and generally promote protein adsorption, whereas the adsorbed amount of protein is similar on methyl-terminated SAMs regardless of solution temperatures at which SAMs are formed.
Effets de deux incorporations d'engrais verts sur le rendement et la nutrition en azote du blé (Triticum aestivum L.), ainsi que sur les propriétés physiques et biologiques du sol

The effects of two applications of green manures (1993 and 1995) on soil physical and biological properties, on wheat (Triticum aestivum L.) yields and N uptake were investigated in 1996 in a Le Bras loam (Humic Gleysol). The green manures as main factor were clover (Trifolium pratense L.), buckwheat (Fagapyrum esculentum L.), millet (Sorghum sudanensis L.), mustard (Brassica hirta Moench), colza (Brassica campestris L.) and a control without green manure. The sub-factors consisted of four N fertilizer rates for subsequent wheat: 0, 30, 60 and 90 kg N ha−1. Green manure application significantly increased the soil water stable aggregates (MWD), and the > 0,25 mm fractions of water-stable aggregates (P < 0,05). Levels of soil microbial biomass, alcaline phosphatase and urease activities, and the N mineralization potential were also significantly increased by green manure treatments compared to the control. A 200 to 300% increase in wheat yields and N uptake were obtained, depending on green manure species,.
Crystal structures and their enumeration via quotient graphs

Abstract Nets – and the quotient-graphs representing nets – are shown to be a powerful tool for the enumeration and analysis of crystal structures. Old and new invariants characterising nets are discussed on the base of a large set of nets. An earlier presented algorithm for the enumeration of crystal structures is revised and extended in order to permit a more directed search for structures possessing certain properties. Particular attention is given to the exclusion of nets, which, by the nature of their connectivity, can not correspond to a crystal structure.
Improved methodology to measure taxon‐specific phosphate uptake in live and unfiltered samples

Microorganisms play a major role in the marine phosphate biogeochemical cycle but the relative contribution of picoplanktonic groups is not well understood. Previous studies have shown that combining uptake measurements of radiolabeled dissolved inorganic phosphate (Pi) substrate with cell sorting by flow cytometry is a powerful tool for the assessment of Pi fluxes at the cell‐specific level. Nevertheless, using 33P to trace Pi uptake, we show that treatments involving fixation and filtration of the sorted groups (i.e., heterotrophic prokaryotes, Synechococcus and piconanophytoeukaryotes) induce leakage of radioactive Pi (up to 50% of the signal), resulting in a sizeable underestimation of the taxon‐specific Pi uptake. We suggest an alternative protocol, which significantly reduces this bias. Using this optimized protocol, the samples were treated with an excess of nonradioactive Pi to stop the incubation and sorted fractions were directly collected in microtubes for radioactivity counting, avoiding signal loss due to filtration. Sorted groups were strongly and differently impacted by fixation (0.5% PFA), with the exception of Synechococcus cells, which showed once a 10% lower signal in samples treated with the previously used protocols compared with samples treated with ours. Based on the integrity of the live sorted cells, our improved protocol provides reproducible and accurate estimations of the taxon‐specific Pi uptake (≤ 11% variation on cellular uptake rates, sd/average, n = 69). It was successfully applied to P‐depleted oligotrophic seawater samples from the Mediterranean and will allow a comparison of taxon‐specific uptake rates between sites.
A density functional study of van der Waals interactions

The applicability of density functional theory(DFT) to van der Waals (vdW) calculations are investigated by using the long-range exchange correction scheme and the Andersson–Langreth–Lundqvist vdW functional. By calculating bond energy potentials of rare-gas dimers, it was found that the present scheme gives much more accurate potentials for all dimers than conventional sophisticated DFT methods do. We therefore confirmed that vdW bonds are constructed under the balance of long-range exchange and vdW correlation interactions, although neither of these interactions are usually contained in pure exchange–correlation functionals. It was also found that calculated vdW potentials are obviously affected by functional forms for rapidly varying densities. Especially in vdW calculations, we must employ a correlation functional that satisfies the fundamental condition for rapidly varying density.
Dielectric Relaxation and Hopping Conduction in La2NiO4+δ

An ac conductivity as well as dielectric relaxation property of La2NiO4.1 is reported in the temperature range of 77 K–130 K and in the frequency range of 20 Hz–1 MHz. Complex impedance plane plots show that the relaxation (conduction) mechanism in this material is purely a bulk effect arising from the semiconductive grain. The relaxation mechanism has been discussed in the frame of electric modulus spectra. The scaling behavior of the modulus suggests that the relaxation mechanism describes the same mechanism at various temperatures. The logarithmic angular frequency dependence of the loss peak is found to obey the Arrhenius law with the activation energy of ~0.09 eV. The frequency-dependent electrical data are also analyzed in the frame of ac conductivity formalism. The ac conductivity has been found to follow a power-law behavior at a limited temperature and frequency region where Anderson localization plays a significant role in the transport mechanism for La2NiO4.1.
Compatibilization of Immiscible Poly(propylene)/Polystyrene Blends Using Clay

Inorganic clay was investigated as a compatibilizer for immiscible poly(propylene)/polystyrene blends. A substantial decrease in the number of polystyrene particles was seen after adding small amounts of an organically treated clay (2-5 wt.-%) to the blends. A possible mechanism for this kind of compatibilization is discussed, but these unique and completely new findings need further verification.
Interfacial and co-existence properties of the Lennard-Jones system at the triple point

A molecular dynamics simulation of the three phases of the Lennard-Jones system in co-existence is reported. The triple-point properties are compared with bulk-phase Monte-Carlo results, with experimental data on argon, and with the results of a preliminary simulation of this system. Thermodynamic properties of the crystal-liquid and liquid-vapour interfaces are reported and difficulties in calculating interfacial excess properties are discussed. The crystal-liquid and liquid-vapour interfacial tensions are in accord with previous predictions. It is suggested that the direct simulation of co-existing phases is a potentially practical route to the phase diagram if the thermodynamic equations of state of the individual phases are known.
Growth of fullerene-like carbon nitride thin solid films consisting of cross-linked nano-onions

Fullerene-like CNx (x≈0.12) thin solid films were deposited by reactive magnetron sputtering of graphite in a nitrogen and argon discharge on cleaved NaCl and Si(001) substrates at 450 °C. As-deposited films consist of 5 nm diam CNx nano-onions with shell sizes corresponding to Goldberg polyhedra determined by high-resolution transmission electron microscopy. Electron energy loss spectroscopy revealed that N incorporation is higher in the core of the onions than at the perimeter. N incorporation promotes pentagon formation and provides reactive sites for interlinks between shells of the onions. A model is proposed for the formation of CNx nano-onions by continuous surface nucleation and growth of hemispherical shells.
You’re the Boss: The Stereotype Content Model as a Predictive Behavioral Tool in Résumé Evaluation Processes

Extensive literature has confirmed that hiring discrimination is a persistent problem; less research has focused on the social cognitive mechanisms of prejudicial hiring and its effects on résumé evaluations. The present study evaluated how stereotyped evaluations of minority candidates could be predicted with the Stereotype Content Model (SCM) dimensions of warmth and competence. No published research has demonstrated how SCM group ratings may predict evaluations of individuals and their qualifications for employment. Participants evaluated two résumés for each of five listed job positions and completed a survey packet. One résumé in each pair suggested membership in a minority group: Muslim, transgender, African American, elderly, or Mexican immigrant. Contrary to expectations, minority signaled candidates were generally viewed more positively than the corresponding non-signaled applicant, and participants were more likely to recommend the minority candidate for the specified job. On the SCM, minority group results replicated past work, but perceptions of minority groups on the SCM did not directly predict résumé evaluations or hiring decisions. SCM ratings were indirectly linked to hiring choices. The more people judged themselves better than society, the more likely they were to hire minority candidates; the more people rated themselves “worse than society” (having less positive views of groups than society), the higher they were in SDO, which was linked to fewer minority hires. Future research on the relationships between the better than average effect, SDO, and the SCM is warranted, as these relationships may become tools used in human resources.
Qualitative and quantitative analysis of pawpaw (Carica papaya) leaf extract and its antimicrobial effect in animal production

In order to improve livestock production and curb the losses from diseases occurrence in livestock, producers resort to the use of antimicrobials as growth promoters to inhibit the growth of disease-causing organisms. Freshly harvested pawpaw leaves were extracted using three solvents: ethanol, methanol and n-hexane and their phytochemicals determined using standard procedure. The inhibitory activities of the extracts at low (200ppm) and high (1000ppm) concentrations against Aspergillus niger and Escherichia coli were also determined. Results obtained showed that alkaloid, flavonoid, saponin, tannin and cardiac glycosides were present while anthraquinone was absent. The percentage yield of phenols using methanol (0.115%) and ethanol (0.214%) solvents were similar but lower than nhexane yield (0.450%). Also the yield of flavonoid using methanol (0.700%) is significantly (p<0.05) higher than the yield using other solvents. The yield of phenols using methanol (0.480%) and ethanol (0.470%) solvents were identical but higher than n-hexane yield (0.400%). At low concentration, it was observed that the inhibitory concentrations ofpawpaw leaf extract against bacteria by control, streptomycin (1.2cm) was significantly (p<0.05) higher but similar to the extract from methanol solvent (1.1cm). Methanol extract inhibition was also similar to ethanol (1.0cm) but higher than n-hexane (0.0cm). At high concentration, the inhibitory activity of the ethanol extract (1.2cm) was significantly (p<0.05) higher than the control (0.7cm) and the least observed in n-hexane (0.0cm) extract. The inhibitory concentrations of pawpaw leaf extract against fungi Aspergillus niger at low (2.2cm) and high (2.2cm) concentrations, the methanol extract was observed to be significantly (p<0.05) higher than other extracts including control. The results suggest that using methanol-extracted pawpaw leaf as alternatives to syntheticantibiotic in animal production is effective against microbial organisms. Thus the occurrence of resistance to antibiotic or its residues on animal products will be reduced.Keywords: Pawpaw; microbes; extraction solvents; phytochemicals; phytobiotics
Distribution of organic carbon in tropical mangrove sediments (Cochin, India)

Surficial sediments were sampled every month from three mangrove regions around the metropolis of Cochin (India). Sedimentary organic carbon content exhibited wide seasonal fluctuations. The hydrology of the mangrove system is regulated mainly by high rainfall during the monsoon and by tidal inundation. The results indicated the role of tidal activity and sediment texture in the preservation and retention of organic matter.
A bandstructure view of the Hume‐Rothery electron phases

The stability of Hume–Rothery's electron phases is studied using modern bandstructure techniques. For these alloys, empirical evidence has shown a strong correlation between the number of valence electrons per atom and the adopted crystal structure. The generally accepted explanation traces the phenomenon to prominent structure in the electron density of states which arises when the free–electron Fermi sphere encounters the Bragg planes at the surface of the Brillouin zone. By applying a rigid band model on the basis of density functional theory to the archetypal system Cu–Zn, we obtain accurate density–of–states functions which are used to critically evaluate the popular models due to Mott and Jones. We also are able to account for the stability of the γ–phase.

Absolute Hydration Free Energy of the Proton from First-Principles Electronic Structure Calculations

The absolute hydration free energy of the proton, ΔGhyd298(H+), is one of the fundamental quantities for the thermodynamics of aqueous systems. Its exact value remains unknown despite extensive experimental and computational efforts. We report a first-principles determination of ΔGhyd298(H+) by using the latest developments in electronic structure theory including solvation effects. High level ab initio calculations have been performed with a supermolecule-continuum approach based on a recently developed self-consistent reaction field model known as surface and volume polarization for electrostatic interaction (SVPE) or fully polarizable continuum model (FPCM). In the supermolecule-continuum approach, part of the solvent surrounding the solute is treated quantum mechanically and the remaining bulk solvent is approximated by a dielectric continuum medium. With this approach, the calculated results can systematically be improved by increasing the number of quantum mechanically treated solvent molecules. ΔGh.
Crystal growth of ZnxCd1−xTe solid solutions and their optical properties at the photon energies of the lowest band‐gap region

Single crystals of ZnxCd1−xTe solid solutions have been grown from a melt under an Ar pressure of about 50 atm. The crystals of uniform composition were grown over the whole range of molar composition, when the crystal growth was performed in excess Zn and/or Cd. A grown boule of 30 × 15 mm φ contained several single‐crystal domains of size 7 × 5 × 5 mm. On the basis of Vegard's law, the molar composition x was determined from x‐ray measurements of lattice constants. The variation of x throughout a single‐crystal domain was found to be less than ± 1%. Optical experiments including transmittance and reflectance measurements have been made on the cleaved (110) planes at room temperature. The variation of the lowest band gap with x was determined from the peak positions in the reflectivity spectra. The bowing parameter, which is a measure of the deviation from the linear change, of this gap was found to be 0.33 eV.
Comparison of phosphorus deficiency effects on the growth parameters of mashbean, mungbean, and soybean

Abstract Experiments were conducted in order to examine the inter-specific difference in low P tolerance in terms of biomass production, photosynthetic rate per unit leaf area (Po) and biological nitrogen fixation (BNF). Three legume species: mashbean (Vigna aconitifolia cv. Mash-88), mungbean (Vigna radiata cv. Moong-6601), and soybean (Glycine max L. cv. Tamahomare) were grown at different levels of P applied in 1993 and 1994. Dry matter production increased in all the species with the increasing P levels. At low P levels up to 25 kg P ha-1 soybean displayed a relatively higher biomass production than mashbean and mungbean, which was mainly caused by the promotion of root growth and leaf area expansion. In low P mashbean plants leaf area development was severely inhibited while Po remained relatively stable in all the species irrespective of the P levels except for extremely low Po at later growth stages without application of P.
