cis-Stereoisomers of β-carotene and its congeners in the alga Dunaliella bardawil, and their biogenetic interrelationships

The acyclic carotenoids phytoene and phytofluene, which are precursors of 9-cis-β-carotene produced by the alga Dunaliella bardawil, have been separated and characterised. Spectroscopic data, and comparison with synthetic model compounds and corresponding carotenoids found in the fruits of the Tangerine tomato Lycopersicon esculentum var. , establish that the pigments have the stereochemistries 15-cis-6 and 9-cis-11 respectively. The data suggest that phytoene 6 is the clear branch point for the formation of 9-cis-β-carotene 2 in D. bardawil. In addition, spectroscopic data for β-carotene isolated from D. bardawil showed that it was isomerically pure 9-cis-β-carotene 2.

Theory of the Linear Dichroism in the Extended X-ray Absorption Fine Structure (EXAFS) of Partially Vectorially Ordered Systems*

Using linearly polarized X-rays for investigations on noncrystalline samples, information on the orientation of the investigated local structure with respect to a nanostructure (e.g., membranes, proteins, layered compounds, and polymers) or a textured macroscopic structure (e.g., a rough surface) may become accessible in case the considered molecular system is partially ordered. For systems with a preferential orientation of one axis of the molecular coordinate system (M, e.g., the membrane normal) with respect to a vector in the macroscopic sample system (S, typically the normal to the macroscopic sample surface), an equation is derived which describes the dependence of the EXAFS on (i) θE, the angle between the X-ray electric field vector and S, (ii) a single order parameter, (iii) θR, the angle between the absorber-backscatterer vector and M. A data-evaluation method is proposed which involves a joint-fit of EXAFS spectra measured for, at least, two excitation angles, θE. Our approach accounts correctl.
Calibration of visible and near infrared spectroscopy for soil analysis at the field scale on three European farms

The development of accurate calibration models for selected soil properties is a crucial prerequisite for successful implementation of visible and near infrared (Vis‐NIR) spectroscopy for soil analysis. This paper compares the performance of calibration models developed for individual farms with that of general models valid for three farms in three European countries. Fresh soil samples collected from farms in the Czech Republic, Germany and Denmark were scanned with a fibre‐type Vis‐NIR spectrophotometer. After dividing spectra into calibration (70%) and validation (30%) sets, spectra in the calibration set were subjected to partial least squares regression (PLSR) with leave‐one‐out cross‐validation to establish calibration models of soil properties. Except for the Czech Republic farm, individual farm models provided successful calibration for total carbon (TC), total nitrogen (TN) and organic carbon (OC), with coefficients of determination (R2) of 0.85–0.93 and 0.74–0.96 and residual prediction deviations (RPD) of 2.61–3.96 and 2.00–4.95 for the cross‐validation and independent validation respectively. General calibration models gave improved prediction accuracies compared with models of farms in the Czech Republic and Germany, which was attributed to larger ranges in the variation of soil properties in general models compared with those in individual farm models. The results revealed that larger standard deviations (SDs) and wider variation ranges have resulted in larger R2 and RPD, but also larger root mean square errors of prediction (RMSEP). Therefore, a compromise solution, which also results in small RMSEP values, should be found when selecting soil samples for Vis‐NIR calibration to cover a wide variation range.
Effect of handling treatment on fillet yields and quality of tropical fish

The effect on fillet yields and quality of the cold shock reaction of tropical fish when they are iced immediately following death was investigated. Tilapia (Oreochromis moss-ambicus/niloticus hybrid) were subjected to three handling treatments: filleting immediately following death; icing the whole fish immediately following death and filleting after 3 days; ageing the fish for 6 hr at ambient temperature prior to icing and then filleting after 3 days. All fillets were stored on ice until 9 days after death. Pre-rigor filleting resulted in the highest filleting yields with the least drip loss and gaping on storage but the shortest shelf life. This was accompanied by the highest post-mortem metabolic rate. The lowest yields and highest drip loss were obtained by icing the fish immediately at death followed by filleting after 3 days. A 6-hr delay before icing gave yields and drip loss which were between these two extremes and also the slowest post-mortem metabolism. The two post-rigor filleting procedures produced fillets with increased gaping but a longer shelf life compared with pre-rigor filleting. The implications of the cold shock reaction in terms of recommended codes of practice and handling operations in tropical fisheries are discussed.
Early construction and operation of the highly contaminated water treatment system in Fukushima Daiichi Nuclear Power Station (III) – a unique simulation code to evaluate time-dependent Cs adsorption/desorption behavior in column system

A simulation code was developed to evaluate the performance of the cesium adsorption instrument operating in Fukushima Daiichi Nuclear Power Station. Since contaminated water contains seawater whose salinity is not constant, a new model was introduced to the conventional zeolite column simulation code to deal with the variable salinity of the seawater. Another feature of the cesium adsorption instrument is that it consists of several columns arranged in both series and parallel. The spent columns are replaced in a unique manner using a merry-go-round system. The code is designed by taking those factors into account. Consequently, it enables the evaluation of the performance characteristics of the cesium adsorption instrument, such as the time history of the decontamination factor, the cesium adsorption amount in each column, and the axial distribution of the adsorbed cesium in the spent columns. The simulation is conducted for different operation patterns and its results are given to Tokyo Electric Power Company (TEPCO) to support the optimization of the operation schedule. The code is also used to investigate the cause of some events that actually occurred in the operation of the cesium adsorption instrument.
Displacement measurements from nanoprecipitates in alloyed Cu single crystals using anomalous small- and wide-angle X-ray scattering

Single crystals of Cu-3Ti, Cu-41.5Ni-16Fe and Cu-23Ni-7Fe (at. %) were studied by anomalous small-angle and wide-angle X-ray scattering in order to determine the displacements induced by the precipitates (ordered Cu 4 Ti rods in the first case or (Ni,Fe) discs in the other cases) as a function of ageing time and temperature. The small-angle scattering patterns give information on the size and arrangement of the precipitates, while the scattering around the Bragg peak allows the elastic lattice distortions around these precipitates to be determined. The precipitates formed in these three alloys are elastically contracted while the matrix enriched in Cu atoms is dilated. This succession of compressed and dilated regions is responsible for the alignment of the precipitates along the elastically soft directions .
Gas solubilities, vapor-liquid equilibria, and partial molal volumes in some hydrogen-hydrocarbon systems

Gas solubilities were measured for hydrogen in n-pentane, 2,3-dimethylbutane, cyclohexane, n-decane, m-xylene, 1,4-diethylbenzene, and 1-methylnaphthalene. Vapor-liquid equilibrium ratios (K's) were measured for the second, third, fifth, and sixth of these systems. Partial molal volumes of hydrogen dissolved in the liquid hydrocarbons were measured for all systems except methylnaphthalene. Temperatures and pressures fell in the ranges 35-320/sup 0/C and 200-2400 psi.
Microstructure of buckwheat and barley during malting observed by Confocal Scanning laser Microscopy and Scanning Electron Microscopy

The structures of buckwheat and barley were observed by Scanning Electron Microscopy (SEM) and Confocal Scanning Laser Microscopy (CSLM) throughout the malting process. SEM and CSLM have different merits when studying grains and seeds. SEM can be used to study the detailed structure (high magnifications can be achieved) and CSLM to study the overall change in structure during processing. SEM proved that buckwheat starch is degraded by both pitting and surface erosion. A concentric sphere structure was visible when buckwheat starch granules were partly broken down. With CSLM, the organization of protein and starch of buckwheat and barley could be examined independently in projections and images visualizing the 3D structure. CSLM proved that buckwheat starch is surrounded by a protein matrix. Buckwheat protein was structured and surrounded starch granules, while barley protein was present in an amorphous mass through the endosperm. The differences in overall structure between unmalted and malted seeds were evident, as the starch and protein in both the barley and buckwheat were degraded. CSLM may be used in the future to couple processing characteristics to the structure of grains and seeds.
Sweet nanodot for biomedical imaging: carbon dot derived from xylitol

We report a facile microwave pyrolysis approach to prepare carbon dots (CDs) using xylitol, a biomass-derived sugar alcohol. Both the surface-passivating agent (ethylenediamine) and HCl are crucial to control the luminescent properties during the synthesis of CDs. CDxy exhibits bright luminescence, aqueous stability, and low cytotoxicity, and thus has high potential for biomedical applications.
Blood Glucose Levels in Students with Stress

: Stress can occur at any lecture level, especially at the initial level. This is in line with previous research which states that, there is increased stress in the first-year students due to changes in learning systems in previous education. The purpose of this research is to know the blood glucose level on students with stress. The type of this research is descriptive using cross sectional design, as many as 24 respondents. Based on levels of glucose to stress levels, the normal group (without stress), whole blood glucose levels within normal limits (100%) ie 7 of 7 respondents. For the mild stress group, there was a normal glucose level of 11 people (78.5%) and high glucose level of 3 people (21.4%). In the moderate group, 3 respondents had high blood glucose level (75%) and only 1 respondent had blood glucose level in normal range (25%). While in the heavy stress group found all respondents with high blood glucose levels (100%). Conclusion, the highest stress level found was mild stress and the higehest blood glucose levels were found to be normal glucose levels.
Crystal structure of the incommensurate modulated composite ruthenate [Ba]1.30[(Ru,Cu)O3]

Abstract [Ba]1.30[(Ru,Cu)O3] crystallizes in a modulated composite crystal structure previously observed for [Ba]x[(Pt,Cu)O3], x = 1.317. The composite structure is refined in one centrosymmetric and one non-centrosymmetric model in the superspace groups P-31c(00γ) and P31c(00γ), respectively, with a = 10.135(1) Å, c = 4.2902(3) Å and q = 1.601(1)c*. The centrosymmetric case was refined using Crenel functions. The first substructure is formed by Ba cations located in channels of the second substructure, which consists of one-dimensional chains of face-sharing polyhedra ∞1[O3/2(Ru,Cu)O3/2]: alternating blocks of mostly three octahedra and trigonal prisms. DC-susceptibility measurements result in typical spin-glass behavior, an effective magnetic moment of μeff = 2. 55μB, and a Weiss temperature of θp = -202 K.
Hydroxyapatite Coating on a Collagen Membrane by a Biomimetic Method

The coating of a carbonate-containing hydroxyapatite (HAp) on a nonbioactive collagen membrane via a biomimetic method has been investigated. The collagen membranes were soaked in a simulated body fluid (SBF) solution with and without citric acid, and carbonate-containing HAp formed only in the SBF solution that contained citric acid. The results were explained in terms of the strong chelation ability of citric acid with the calcium ion. Practical application may involve the inclusion of citric acid in the SBF solution to promote the formation of HAp on previously nonbioactive collagen membranes.
Acetone, methanol, and other partially oxidized volatile organic emissions from dead plant matter by abiological processes: Significance for atmospheric HOx chemistry

In this paper, attention is called to the significance of abiological production of partially oxidized volatile organic carbons (POVOCs) from the decay of dead plant material. Measured relative emission of acetone and methanol can be at least 10−4 and 3 ‐ 5 × 10−4 g g−1of decaying dry plant matter, respectively. If these results may be extrapolated, global annual emissions of 6–8 Tg of acetone and 18 – 40 Tg of methanol would result, adding strongly to the estimated total emissions of these compounds to the atmosphere. Because acetone and methanol, through OH and HO2 formation, play significant roles in the chemistry of the atmosphere, further research is strongly needed to quantify the emissions of acetone, methanol, and other POVOCs
Atmospheric deposition of metals in romania studied by biomonitoring using the epiphytic moss hypnum cupressiforme

The results obtained from a study using the epiphytic moss species Hypnum cupressiforme to estimate heavy-metal atmospheric deposition in the province of Moldavia (Romania) are presented. The present study is a part of a biomonitoring programme in Moldavia and could serve as a starting point for further planning of biomonitoring using new moss species in regions where the commonly used Hylocomium splendens and Pleurozium schreberi are not present. Moss samples were collected within the catchment of Prut, a border river between Romania, Republic of Moldova and Ukraine, at a total of 25 sampling points and analysed for a wide range of elements, most of them heavy metals. The samples were analysed by instrumental neutron activation analysis using epithermal neutrons (ENAA) for 40 elements. Using inductively coupled plasma-mass spectrometry (ICP-MS), the elements Cd, Tl, Pb, V, Cr, Ni, Zn, As, Mo, Ag, In, and Bi were determined. Atomic absorption spectrometry (AAS) was used for the determination of Cd, Cu, Pb and Zn. Distribution maps were drawn for nine elements (As, Cd, Cr, Cu, Fe, Pb, Se, V, and Zn). By means of moss monitoring, it was possible to characterize most of the industrial and local sources of pollution within the studied area. The values are lower than those found in the western part of Romania, and the distribution of certain elements (As, Cu, Zn) reflects the predominant agricultural activities in eastern Romania. The highest levels of elements were found in the most industrialised and populated areas of Moldavia. Significant correlations were observed for the results obtained by different analytical techniques.
Soil tests for predicting the N requirement of corn

Several soil N tests were compared with the one currently used for predicting the N requirement for corn in Ontario. The current test involves a measurement of nitrate (NO3−, 0–30 cm) before N fertilizer sidedressing. The study was done to determine the efficacy of other tests for N fertilizer prediction. The tests chosen varied in the quantity of N “extracted” and included hot KCl-extractable NH4+, anaerobically released NH4+, extractable NH4+ following autoclaving in CaCl2 solution and total N of soil sampled to a depth of 30 cm. The 3-yr study was conducted on a sloped (simple) field site, which provided a wide range in soil organic matter (SOM) contents. A corn crop was grown each year following a barley crop with or without red clover cover crop residues incorporated in the spring and with or without N fertilization. Corn grain yields were obtained at the end of the growing season. Grain yields were lowest at the shoulder and backslope locations and highest at the footslope and toeslope locations. Co.
Evaluation of constitutive relations for high strain rate behaviour using the Taylor test

Taylor tests have been performed on specimens of ten metallic materials. The different one - dimensional models have been used. In the next step the finite element code LS DYNA has been used in order to deduce the parameters in the Johnson - Cook constitutive equations Using of the mutual comparison of the computed specimen profile with experimental one led to the explanation of the influence of the parameters mentioned above on the deformation behaviour determined by the computation. This procedure also made possible to choose the constitutive equation which represents the optimum estimation of material behaviour at high strain rates.
Oxidative Decolorization of Reactive Dye Solution Using Fly Ash as Catalyst

This paper deals with the potential of coal fly ash as a heterogeneous catalyst in peroxidative decolorization of aqueous solution of several reactive drimarene dyes using hydrogen peroxide (H\d2O\d2). The effects of various parameters (source of fly ash, fly ash loading, temperature, pH, initial concentration of dye and hydrogen peroxide, and deactivation of catalytic effect of fly ash) were studied. The rate of decolorization is zero order with respect to concentration of dye in the range of 50–200 mg/L and first order with respect to concentration of H\d2O\d2 in the range of 375–2,500 mg/L. It was found that at 333 K and pH 2.0, only 2% (weight/volume) fly ash loading can completely decolorize 100 mg/L dye solution within 180–1,770 s for an initial H\d2O\d2 concentration of 1,500 mg/L, depending on the source of fly ash and dye used. But maximum 25% decolorization was noticed after 3.0-h duration of reaction without fly ash. The negligible homogeneous catalytic action of trace amount of metals like Fe, Mn, and Cu leached from the fly matrix confirmed the sole heterogeneous catalytic nature of fly ash particles in decolorization reactions. The deactivation of fly ash was found to be <30% in nine repeated uses. Adsorption dynamics and mechanism of dyes onto fly ash also were studied in the absence of H\d2O\d2.
Production of penicillin-specific polyclonal antibodies for a group-specific screening ELISA

Abstract Polyclonal penicillin-specific antibodies were obtained after the immunization of three rabbits with physiological penicillin-protein conjugates. The broad-specificity of the antisera was improved by alternate immunizations using immunogens with different penicillins as hapten. For the three antisera, the detection of ampicillin, amoxicillin, benzylpenicillin, oxacillin, cloxacillin and dicloxacillin was more sensitive in a competitive ELISA coated with the antibodies (antibody cELISA) compared to a competitive ELISA coated with a penicillin-protein conjugate (antigen cELISA). The detection of all penicillins in buffer solutions at concentrations below the MRL was achieved in the antibody cELISA when the penicillins were hydrolyzed with Penicillinase I. A simple extraction procedure was developed for the detection of penicillins in incurred porcine tissues using the antibody cELISA. Tissue fluids were used instead of the whole meat matrix, which simplified the sample preparation. Before analysis, the fluids were treated with kaolin to reduce the background signals in ELISA. The specificity, sensitivity, repeatability, decision limit (CCα) and detection capability (CCβ) were determined. The suitability of the antibody cELISA and the respective extraction procedure for screening purposes was demonstrated by comparison of the analysis of incurred samples using different screening assays. Almost 100% correlation (r=0.96) was found between the ELISA and a commercial immunochemical method, the Parallux™ assay.

Mineral element content of chamomile

Mineral components play an important role as adjuvants in the therapeutical activity of chamomile. Considering their content in the different species, an interesting observation was that the wild populations are richer in distribution of mineral elements than the cultivated Degumil type, while ratios of K/Na and Ca/Mg in this cultivated type are many times higher than in wild chamomile populations. Chamomile tea extract (infusion) is widely used in digestion complains. Macro- and microelement content of the infusion is relatively low in which relatively high concentrations of potassium, calcium and magnesium were found. The dissolution of mineral elements in tea was between 10% and 26% for most of the elements with the highest value attributed to magnesium (26%).
Role of Molybdenum on Yield, Quality, and Photosynthetic Efficiency of White Clover as a Result of the Interaction with Liming and Different Phosphorus Rates in Andisols

A greenhouse study was conducted to determine the effects of liming, molybdenum (Mo), and phosphorus (P) rates on yield, mineral and nutritional quality, and photosynthetic efficiency of Trifolium repens L. in two Andisols. The experiment used a factorial design with four, three, and two rates for Mo, P, and lime. Molybdenum and P application increased both shoot dry weight and Mo shoot concentration (10–30%). A strong competition for sorption sites between phosphate and molybdate resulted in an increase of available Mo in soil solution and therefore an increase of Mo uptake (20–40%). Significant increases (P ≤ 0.05) were observed in plants' mineral and nutritive quality and photochemical efficiency. This effect was greater in limed soils. Our results suggest a SPAD 50 value can be used as indicator of an adequate N shoot concentration in T. repens, and Mo fertilization is required to improve pasture yield and quality for livestock production.
