    The effects of deuterium oxide (D 2 O) on giant internodal cells of the fresh water alga Chara gymnophylla, were investigated. D 2 O causes membrane excitation followed by potassium leakage. The primary effect consists of an almost instantaneous membrane depolarization resembling an action potential with incomplete repolarization. A hypothesis was proposed which deals with an osmotic stress effect of D 2 O on membrane ion channels followed by the suppression of the electrogenic pump activity. The initial changes (potential spike and rapid K+ efflux) may represent the previously undetected link between the D 2 O-induced temporary arrest of protoplasmic streaming and the early events triggered at the plasma membrane level as the primary site of D 2 O action

    The Sudbury Neutrino Observatory (SNO) has been collecting data since November 1999. The study of whether or not the D 2 O circulation affects the data is an important part of understanding how the SNO detector behaves. This report looks at several characteristics of the data to determine to what extent the D 2 O circulation affects the data. We found that there is no evidence for any dependence of event rates in the cleaned data sets on the state of D 2 O circulation

  4. Physical limit of stability in supercooled D2O and D2O+H2O mixtures

    The fluctuation theory of homogeneous nucleation was applied for calculating the physical boundary of metastable states, the kinetic spinodal, in supercooled D2O and D2O+H2O mixtures. The kinetic spinodal in our approach is completely determined by the surface tension and equation of state of the supercooled liquid. We developed a crossover equation of state for supercooled D2O, which predicts a second critical point of low density water-high density water equilibrium, CP2, and represents all available experimental data in supercooled D2O within experimental accuracy. Using Turnbull's expression for the surface tension we calculated with the crossover equation of state for supercooled D2O the kinetic spinodal, TKS, which lies below the homogeneous nucleation temperature, TH. We show that CP2 always lies inside in the so-called "nonthermodynamic habitat" and physically does not exist. However, the concept of a second "virtual" critical point is physical and very useful. Using this concept we have extended this approach to supercooled D2O+H2O mixtures. As an example, we consider here an equimolar D2O+H2O mixture in normal and supercooled states at atmospheric pressure, P=0.1 MPa.

    Melting points for the tetrahydrofuran/D 2 O hydrate in equilibrium with the air-saturated liquid at atmospheric pressure are reported. The melting points were measured by monitoring the absorbance of the solution. Overall, the melting-point phase boundary curve is about 2.5 K greater than the corresponding curve for the H 2 O hydrate, with a congruent melting temperature of 281 ± 0.5 K at a D 2 O mole fraction of 0.936. The phase boundary is predicted to within 5% if the assumption is made that the THF occupancy in the D 2 O and H 2 O hydrates is the same. The authors measure an occupancy of 99.9%. The chemical potential of the empty lattice in D 2 O is estimated to be 5% greater than in H 2 O

    There is a great number of works on surface tension of clean water (H 2 O) at temperatures up to 100 deg C and very few above the boiling point. Works on surface tension of heavy water (D 2 O) are insufficient. A review of works on surface tension of both kinds of water is given

    1996-01-01

    The cellular cycle of the Saccharomyces Cerevisiae, chosen as experimental object, is unmodified by the presence in the culture medium of D 2 O at different concentrations. An increased concentration of D 2 O in the culture medium leads to a decrease of the number of budded cells, to metabolic alterations, to DNA structure modification as well as to enzymatic changes produced by blocking. Other anomalies appear, as a function of the cell defence capacity and of the influence of the factors from the nutrient substrate or exterior medium. Due to D 2 O, the medium's pH changes and modifications at the enzyme level and of the cell microstructure and morphology occur. The enzymatic reactions take place in D 2 O slower than in H 2 O. Three-dimensional modifications appear in the organic components of the live cell which, in turn, produce profound modifications in the cell growth and division. Due to the kinetic and isotopic effects, modifications of the biochemical reactions affecting the cell integrity happen

    1989-01-01

    Excessively dorsalized embryos of Xenopus laevis develop from eggs treated with 30-70% D 2 O for a few minutes within the first third of the cell cycle following fertilization. As the concentration of D 2 O and the duration of exposure are increased, the anatomy of these embryos shifts in the direction of enlarged dorsal and anterior structures and reduced ventral and posterior ones. Twinning of dorsoanterior structures is frequent. Intermediate forms include embryos with large heads but no trunks or tails. The limit form of the series has cylindrical symmetry, with circumferential bands of eye pigment and cement gland, a core of notochord-like tissue, and a centrally located beating heart. D 2 O treatment seems to increase the egg's sensitivity to the dorsalizing effects of cortical rotation and to stimulate the egg to initiate two or more directions of rotation. Such eggs probably establish thereafter a widened and/or duplicated Nieuwkoop center in the vegetal hemisphere, with the subsequent induction of a widened and/or duplicated Spemann organizer region in the marginal zone, which leads to excessive dorsal development. The existence of these anatomical forms indicates the potential of the egg to undertake dorsal development at all positions of its circumference and suggests that normal patterning depends on the limited and localized activation or disinhibition of this widespread potential

    The rovibrational spectra of the N2-D2O and OC-D2O complexes in the v2 bend region of D2O have been measured in a supersonic slit jet expansion using a rapid-scan tunable diode laser spectrometer. Both a-type and b-type transitions were observed for these two complexes. All transitions are doubled, due to the heavy water tunneling within the complexes. Assuming the tunneling splittings are the same in K(a) = 0 and K(a) = 1, the band origins, all three rotational and several distortion constants of each tunneling state were determined for N2-D2O in the ground and excited vibrational states, and for OC-D2O in the excited vibrational state, respectively. The averaged band origin of OC-D2O is blueshifted by 2.241 cm(-1) from that of the v2 band of the D2O monomer, compared with 1.247 cm(-1) for N2-D2O. The tunneling splitting of N2-D2O in the ground state is 0.16359(28) cm(-1), which is about five times that of OC-D2O. The tunneling splittings decrease by about 26% for N2-D2O and 23% for OC-D2O, respectively, upon excitation of the D2O bending vibration, indicating an increase of the tunneling barrier in the excited vibrational state. The tunneling splittings are found to have a strong dependence on intramolecular vibrational excitation as well as a weak dependence on quantum number K(a).

  10. Definitive difference among [DS-D2O], [DS-H2O] and [Bulk-D2O] cells in the deuterization and deuterium-reaction

    We observed a new phenomena that the enormous amount of deuterium/hydrogen can be absorbed quickly as a 'solute-atom' into fine metal powders embedded inside a double-structure (DS) cathode in the electrolyses of D 2 O and H 2 O-electrolytes, respectively, but such highly deuterated powders can be produced only using DS-cathode immersed in D 2 O-electrolyte; [DS-D 2 O], and never generated in H 2 O-electrolyte even using the DS-cathode; [DS-H 2 O]. On the other hand, [Bulk-D 2 O] with bulk-cathode made by the bulk Pd metal never produces highly deuterated metal as mentioned above even though using D 2 O-electrolyte. In short, the deuterium-concentration generating in [Bulk-D 2 O] is found to be much lower than that in [DS-D 2 O]. As a result, because of reason mentioned above, in marked contrast to the case with the [DS-D 2 O], neither excess heat nor 4 He production are observed with both [DS-H 2 O] and [Bulk-D 2 O].

  11. Determination of the evaporation coefficient of D2O

    2008-11-01

    Full Text Available The evaporation rate of D2O has been determined by Raman thermometry of a droplet train (12–15 μm diameter injected into vacuum (~10-5 torr. The cooling rate measured as a function of time in vacuum was fit to a model that accounts for temperature gradients between the surface and the core of the droplets, yielding an evaporation coefficient (γe of 0.57±0.06. This is nearly identical to that found for H2O (0.62±0.09 using the same experimental method and model, and indicates the existence of a kinetic barrier to evaporation. The application of a recently developed transition-state theory (TST model suggests that the kinetic barrier is due to librational and hindered translational motions at the liquid surface, and that the lack of an isotope effect is due to competing energetic and entropic factors. The implications of these results for cloud and aerosol particles in the atmosphere are discussed.

    The transfer of stopping π - mesons from hydrogen to deuterium has been investigated in mixtures of H 2 O+D 2 O as a function of D 2 O concentration. The concentration dependence of the transfer probability is similar to that observed for the gas mixtures of H 2 and D 2 but slightly more transfer is found for H 2 O+D 2 O.

    Advective-diffusive transport of HTO in unsaturated media was investigated empirically using deuterated water (D 2 O) and columns filled with glass beads. The tortuosity factor was evaluated by numerical model calculations corresponding to first experiment for diffusion under no-evaporation condition. Temporal variations in depth profiles of D 2 O concentrations in the columns were observed by second experiment, which considers the transferring and spreading of D 2 O by pore-water flow caused by evaporation. Measurements and model calculations indicated that diffusion was about two times more efficient than dispersion for D 2 O spreading process under this evaporation condition. (author)

    A simple low-cost procedure was developed to compare the temporal profiles of deuterium oxide (D 2 O) accumulation in body fluids after ingestion of D 2 O-labeled solutions. D 2 O concentration was measured in plasma and saliva samples taken at various intervals after ingestion of 20 ml of D 2 O mixed with five solutions differing in carbohydrate and electrolyte concentrations. An infrared spectrometer was used to measure D 2 O in purified samples obtained after a 48-h incubation period during which the water (D 2 O and H 2 O) in the sample was equilibrated with an equal volume of distilled water in a sealed diffusion dish. The procedure yields 100% recoveries of 60-500 ppm D 2 O with an average precision of 5%. When compared with values for distilled water, D 2 O accumulation in serial samples of plasma and saliva was slower for ingested solutions containing 40 and 15% glucose and faster for hypotonic saline and a 6% carbohydrate-electrolyte solution. These differences appear to reflect known differences in gastric emptying and intestinal absorption of these beverages. Therefore, this technique may provide a useful index of the rate of water uptake from ingested beverages into the body fluids

  19. In vitro histamine release from basophils of asthmatic and atopic individuals in D2O

    Tung, R.; Lichtenstein, L.M.

    1982-01-01

    It was found that spontaneous histamine release from human basophils in H 2 O-based buffers is negligible; in D 2 O-based buffers, however, release is observed with the cells of some donors. Analysis of this phenomenon revealed release from the basophils of 1 of 22 control individuals (5%), 15 of 47 patients with allergic rhinitis (32%), and 14 of 20 asthmatic patients (70%). The difference between both patient groups and controls and between atopics and asthmatics was highly significant. That D 2 O release was not cytotoxic is suggested by the finding that 37 0 was optimal, with inhibition at 4 0 C or 46 0 C as well as by EDTA, 2-deoxyglucose, and dibromoacetophenone, an inhibitor of phospholipase A 2 . The release mechanism was unusual in that dibutyryl cAMP and agonists that cause an increase in cAMP lead to no inhibition. No correlation was noted between the total serum IgE level (and thus the number of IgE receptors on the basophil surface) and the magnitude of D 2 O release. No increase in D 2 O release was observed in 17 ragweed-sensitive patients through a ragweed season. A unique property of D 2 O release was the loss of reactivity by preincubating cells at 37 0 C for 30 min before adding D 2 O. Non-D 2 O-reactive cells could be ''converted'' to D 2 O-reactive cells by incubation with antigen in the whole blood phase during leukocyte isolation; these cells showed the same loss of releaseability at 37 0 C and an inhibitor profile similar to D 2 O-responsive cells from ragweed allergic or asthmatic patients. We suggest that D 2 O-based buffers reveal, in atopic and asthmatic patients, in vivo basophil activation; whether this is due to IgE cross-links, to C split products, or to other stimuli is not yet clear

  20. Reversible Chromatic Response of Polydiacetylene Derivative Vesicles in D2O Solvent.

    The thermal chromatic sensitivity of polydiacetylenes (PDAs) with 10,12-pentacosadiynoic acid (PCDA) derivatives, which have a hydroxyl group (HEEPCDA) and an amine group (APPCDA), were investigated using D2O and H2O as solvents. The vesicle solution with polymerized HEEPCDA exhibited a reversible chromatic response during the heating and cooling cycle in D2O, but not in H2O. On the other hand, the vesicle solution with the polymerized APPCDA exhibited a reversible chromatic response in H2O during the heating and cooling cycle, but the color of the solution did not change much in D2O. The critical vesicle concentration of HEEPCDA was lower in D2O than in H2O, and the chromatic sensitivity of the polymerized vesicles to temperature was slower in D2O than in H2O. We think that it is due to D2O being a more highly structured solvent than H2O with the hydrogen bonding in D2O stronger than that in H2O.

    1998-01-01

    Deuterium, a stable isotope of tritium, was released into a vinyl house in autumn 1995 and summer 1996 to study the transfer of tritium from air to plant and soil. Temporal variation of D 2 O concentrations in plant and soil water, and plant physiological parameters such as transpiration rate and leaf temperature, were measured during these experiments. D 2 O concentrations of plants were fitted to a first order kinetic model: C p =C max (1-e -kt ), where C p is the D 2 O concentrations in plants at time t, C max is the steady-state concentration in plants and k is the rate constant. The rate constant was also calculated using measured plant physiological parameters for comparison. The D 2 O uptake by paddy rice was most rapid and the value of k was 3.63±0.31 h -1 followed by radish, cherry tomato, komatsuna and orange. The day/night concentration ratio for cherry tomato and orange was higher than that for radish and komatsuna. (orig.)

    In present paper, we report the production and detailed structural analysis of deuterium-enriched rye grass (Lolium multiflorum) for neutron scattering experiments. An efficient method to produce deuterated biomass was developed by designing hydroponic perfusion chambers. In preliminary studies, the partial deuterated rye samples were grown in increasing levels of D2O to study the seed germination and the level of deuterium incorporation as a function of D2O concentration. Solution NMR method indicated 36.9 % deuterium incorporation in 50 % D2O grown annual rye samples and further significant increase in the deuterium incorporation level was observed by germinating the rye seedlings in H2O and growing in 50 % D2O inside the perfusion chambers. Moreover, in an effort to compare the substrate characteristics related to enzymatic hydrolysis on deuterated and protiated version of biomass, annual rye grown in 50 % D2O was selected for detailed biomass characterization studies. The compositional analyses, degree of polymerization and cellulose crystallinity were compared with its protiated control. The cellulose molecular weight indicated slight variation with deuteration; however, hemicellulose molecular weights and cellulose crystallinity remain unaffected with the deuteration. Besides the minor differences in biomass components, the development of deuterated biomass for neutron scattering application is essential to understand the complex biomass conversion processes.

    Kondo, M.; Kawanowa, H.; Gotoh, Y.; Souda, R.

    2004-01-01

    The interaction of HCl with the D 2 O-ice surface has been investigated in the temperature range 15-200 K by utilizing time-of-flight secondary ion mass spectroscopy, temperature-programmed desorption, and x-ray photoelectron spectroscopy. The intensities of sputtered H + (D 2 O) and Cl - ions (the H + ions) are increased (decreased) markedly above 40 K due to the hydrogen bond formation between the HCl and D 2 O molecules. The HCl molecules which form ionic hydrates undergo H/D exchange at 110-140 K and a considerable fraction of them dissolves into the bulk above 140 K. The neutral hydrates of HCl should coexist as evidenced by the desorption of HCl above 170 K. They are incorporated completely in the D 2 O layer up to 140 K. The HCl molecules embedded in the thick D 2 O layer dissolve into the bulk, and the ionic hydrate tends to segregate to the surface above 150 K

    Accurate measurements of heavy water ice vapour pressures between 193 and 253 K have been carried out and an equation based on thermodynamic data has been derived in order to calculate the D 2 O-ice vapour pressures between 173 and 273 K. The agreement between our calculated vapour pressures and the available experimental data including those in this paper, is very good. The comparison between the theoretical calculations of H 2 O-ice and D 2 O-ice vapour pressures confirms the experimental evidence that H 2 O-ice is more volatile than D 2 O-ice at all temperatures in agreement with the vapour isotopic effect theory (VPIE).(author)

  5. Vibrational relaxation of a triatomic molecular impurity: D2O in vitreous As2S3

    1995-01-01

    Measurements of the relaxation of the D 2 O stretch mode in vitreous As 2 S 3 are presented. Because the bending mode of the molecule offers an intra-molecular decay channel for the stretch mode, the decay scheme of the D 2 O molecule is more complex than that of diatomic molecules. The asymmetric stretch mode of D 2 O has a frequency of 2680 cm -1 . To study the relaxation of this mode we applied a pump-probe technique, using intense psec; pulses of the Stanford Free Electron Laser. Due to the small cross-section of the vibrational mode, successful efforts were made to improve the signal to noise ratio by using a laser stabilization system and a tightly focused beam to increase the intensity, by averaging the signal with a kHz repetition rate and by using samples with an optimized D 2 O concentration. A rapid relaxation rate on the order of 5 x 10 9 sec -1 at low temperature is found that increases with temperature. Recalling that the bending mode of the D 2 O molecule has a frequency of 1170 cm -1 , one would expect a decay in a third order process, involving two quanta of the bending mode plus a vibrational host quanta with a frequency of 340 cm -1 , which coincides with a fundamental frequency of the pyramidal building blocks of the glassy As 2 S 3 host. Instead, we find from the temperature dependence of the relaxation rate that the D 2 O stretching mode relaxes in a higher order process. This indicates that the relaxation dynamics of small molecules is more complex than generally assumed

  6. Effects of D2O on biochemical parameters of normal cells and tumour cells

    Biesewig, G.

    1975-01-01

    The influence of high temperatures (Hyperthermia) on normal tissue and Ehrlich-Ascites tumour cells ('ATZ') was examined under several conditions with regard to the application of deuterium oxide as a stabilising factor. It was proven that the DNA-synthesis of normal tissue (liver, mouse) is not sensitive to temperature. This effect of hyperthermia only occurs when the tissue is damaged, e.g. by trypsinising. The influence of hyperthermia on several biochemical parameters and on morphological changes of the Ascites cells was examined. The findings show that deuterium oxide (D 2 O) is able to reduce both the thermal and the ureal denaturation of enzymes. Thus tests were carried out to find out if D 2 O also reduces toxic influence in complicated biological systems. The assumption of high D 2 O concentrations to prevent several reactions was confirmed. When the Ascites tumour cells in the H 2 O-buffer were exposed to the damaging influence of hyperthermia, the high degree of damage was seen with the decreasing DNA synthesis, reduced aerobic glycose capacity, a drop in the ATP values and breakdown of the permeability of the membrane. Deuterium oxide was able under high temperature (from appr. 44 0 C on) to reduce the degree of damage to DNA synthesis, while auto-effects (inhibition of synthesis) of D 2 O predominate in the lower region. Aerobic glycolysis was damaged in both cases to the same degree, however. In D 2 O after hyperthermia the ATP-level dropped faster than in H 2 O. D 2 O not only reduces the thermal denaturation of the Ascites tumour cells, but it also eliminates the toxic influence of the zytostaticum TRENIMONsup(R) (under 38 0 or 46 0 C incubation).

    SANS of Na+-iota-carrageenan in D2O/saline solutions was measured as a function of concentration, temperature and type of counterions (K+ or Na+). High and low scattering-contrasted gels and solutions were detected. High contrast is caused by aggregation of low-hydrated chains at high concentration...

  9. The H2O/D2O exchange across vesicular lipid bilayers

    Engelbert, H.P.; Lawaczek, R.

    1985-01-01

    A new method to measure the water (D 2 O/H 2 O) permeation across vesicular lipid bilayers is described. The method is based on the solvent isotope effect of the light scattering which is a consequence of the different indices of refraction of D 2 O and H 2 O. Unilamellar lipid vesicles in excess of H 2 O are rapidly mixed with D 2 O or vice versa. As result of the H 2 O/D 2 O exchange across the vesicular bilayer the light scattering signal has a time dependent, almost single exponential component allowing the deduction of the exchange relaxation rate and, at known size, of the permeability coefficient. The experimental results are in accord with calculations from the Mie theory of light scattering for coated spheres. The method is applicable for large vesicles where the permeation is the rate-limiting step. Size separations are performed by a flow dialysis through a sequence of pore-membrane-filters. For dimyristoyl-lecithin bilayers the water permeability-coefficient is 1.9 . 10 -5 cm/s in the crystalline phase and increases by a factor of 10-100 in the liquid-crystalline state. The temperature dependence of the permeation exhibits a sharp change at the phase transition. For binary mixtures of lecithins this sharp change follows the solidus curve of the non-ideal phase diagram determined by spectroscopic techniques. (orig.)

  10. Effects of substituting D2O for H2O on SANS measurements of hydrating cement

    International Nuclear Information System (INIS)

    Sabine, T.M.; Prior, M.J.

    2002-01-01

    Full text: Small angle neutron scattering (SANS) measurements of cement have been found useful in the investigation of the shape and growth of particles formed during hydration. Calorimetric measurements of hydrating cement samples have shown that the substitution of D 2 O for H 2 O has the effect of slowing the hydration process. In order to throw some light on this phenomenon, we have measured SANS profiles from cement samples hydrating in H 2 O and D 2 O. This involved obtaining SANS profiles at half-hourly intervals during the initial stage of hydration. The only instruments capable of this at present are located at the Hahn-Meitner Institute in Berlin and at the Nuclear Physics Institute at Rez near Prague. Initial experiments carried out on the V12a UltraSANS diffractometer at The Hahn-Meitner Institute were only partially successful owing to excessive multiple scattering in the D 2 O samples. Subsequent measurements were therefore carried out on the similar instrument at Rez near Prague which operates at a shorter neutron wavelength. Results from these measurements show profound differences in the evolution of cements hydrating in D 2 O and those hydrating in H 2 O

    We demonstrate the guiding of a supersonic heavy-water (D 2 O) molecular beam using a hollow electrostatic field generated by the combination of two parallel charged-wires and two grounded metal-plates, and report some new and preliminary experimental results. In the experiment, we detect the guiding signals by using the method of time-of-flight mass spectrum and study the dependence of the relative transmission of the beam guide on the guiding voltage. Our study shows that the relative transmission of the beam guide is increased linearly with increasing guiding voltage V guid , and the number of the guided D 2 O molecules is at least increased by 89.4% when the guiding voltage is +20.0 kV. Finally, some potential applications of our guiding scheme in the molecule optics are briefly discussed. (authors)

    Cholesterol synthesis in cell culture in the presence of D 2 O yields a spectrum of enriched molecules having a relative abundance that indicates random substitution of deuterium for hydrogen. Quantitation of the absolute rate of cholesterol synthesis is obtained by isotope ratio mass spectrometry. Mevinolin and 26-hydroxycholesterol both decrease cholesterol synthesis rate but have a discordant effect on HMG-CoA reductase activity

    The mode structures in an optically pumped D 2 O far infrared ring laser and a corresponding linear resonator have been compared. While single mode operation can be obtained over the whole useful pressure range in the ring structure, this is only possible at pressures greater than 8 Torr in the linear resonator case. A numerical model predicts quite well the pulse shape, pressure dependence and influence of the resonator quality in the ring cavity. (author) 12 figs., 8 refs

  15. The reactions of neutral iron clusters with D2O: Deconvolution of equilibrium constants from multiphoton processes

    Weiller, B.H.; Bechthold, P.S.; Parks, E.K.; Pobo, L.G.; Riley, S.J.

    1989-01-01

    The chemical reactions of neutral iron clusters with D 2 O are studied in a continuous flow tube reactor by molecular beam sampling and time-of-flight mass spectrometry with laser photoionization. Product distributions are invariant to a four-fold change in reaction time demonstrating that equilibrium is attained between free and adsorbed D 2 O. The observed negative temperature dependence is consistent with an exothermic, molecular addition reaction at equilibrium. Under our experimental conditions, there is significant photodesorption of D 2 O (Fe/sub n/(D 2 O)/sub m/ + hν → Fe/sub n/ + m D 2 O) along with ionization due to absorption of multiple photons from the ionizing laser. Using a simple model based on a rate equation analysis, we are able to quantitatively deconvolute this desorption process from the equilibrium constants. 8 refs., 1 fig

    Numerous publications on the thermophysical data of heavy water (D 2 O) have been published since D 2 O became commercially available in the 1930's. Some of these data are in mutual disagreement. This has led to confusion among the scientifical and technical staffs who needed the information on the D 2 O thermophysical data. Correct thermophysical data must be consistent, i.e. their mutual relations must be in accordance to the fundamental thermophysical laws. The work behind this publication has been focussed at collecting all avalilable D 2 O data and checking the data mutually by means of these fundamental thermophysical criteria. Depending on the various production methods, the oxygen content of the D 2 O is enriched more or less in the heavier oxygen isotopes 17 O and 18 O. This, together with the amount of impurities and dissolved gases in the D 2 O samples of the various references, might - to some extent - explain the discrepancies between the data sources. Only a few references contain information on these subjects. The D 2 O data sets which were found to be the most reliable are presented in chapter 9, in tables as well as in diagrams, together with the corresponding H 2 O data for comparison. The diagrams are commented for reliability where it was found necessary. Furthermore, the publication contains short descriptions on the heavy water sources, availability, production processes, economy, material and energy demands for production. A comprehensive list of references is enclosed. (author)

    We have achieved single mode operation in a hybrid optically pumped D 2 O far infrared laser. The active volume of the resonator was divided into two sections separated by a thin plastic foil. The larger section served as the main gain medium and the shorter section as mode selective element. The vapor pressure in the smaller volume was either very low or alternatively about 3 times higher than the pressure in the main part. In both cases single mode operation was achieved without any reduction of the total output energy. (author) 13 refs., 7 figs

    Using RSYST a program cycle for corephysics calculations has been compiled and successfully tested in solving the D 2 O-Benchmarkproblem of IAEA. In Cell calculations ANISN has been used, a reprogrammed version of Origen for burnup and Citation as diffusion code for XY-core calculations. Calculations for multigroup constants including cell calculations have been done in parallel to RSYST with AMPXII too, which showed nearly the same results, small differences certainly due to use of different databases and/or numerical methods. The stepwise proof of data and programs led to numerous parameter calculations the resuslts of which are reported too. (orig.) [de

    The feasibility of refractometry for rapid measurement of D 2 O (heavy water) concentration has been studied. Refractometry has been utilised to be an excellent analytical technique to quickly and non-invasively determine D 2 O concentration in water samples without using any chemical reagents. The measurement of refractive index property of water samples with use of temperature control has been utilized for the purpose of their quantitative analysis. The calibration performance provided a reasonable analytical sensitivity of this technique in the 1-100% D 2 O range. (author)

    A velocity selected molecular beam of D 2 O was crossed with a nozzle beam of Ar and the angular distribution of the scattered D 2 O was measured mass spectrometrically. By varying the velocity of the D 2 O beam, the differential cross section was measured at two collision energies. The experimental results were compared with synthetic differential cross sections calculated from Lennard-Jones and Kihara-Stockmayer trial potentials to determine potential parameters. Implications for the H 2 O pair potential are discussed

    Rapid atomic power deployment may be possible without using fast breeder reactors or making undue demands on uranium resource. Using by-product D2O and thorium-U233 in CANDU and RBMK piles may circumvent need for either fast breeder reactors or seawater uranium. Atmospheric CO2 is presently increasing 2.25%/year in proportion to 2.25%/year exponential fossil fuel consumption increase. Roughly 1/3 anthropologic CO2 is removed by various CO2 sinks. CO2 removal is modelled as being proportional to 45-year-earlier CO2 amount above 280 ppm-C Water electrolysis produces roughly 0.1 kg-D20/kWe-y. Material balance assumes each electrolysis stage increases D2O bottoms concentration times 3. Except for first two electrolysis stages, all water from hydrogen consumption is returned to electrolysis. The unique characteristic of this process is the ability to economically burn all deuterium-enriched H2 in vehicles. Condensate from vehicles returns to appropriate electrolysis stage. Fuel cell condensate originally from reformed natural gas may augment second-sage feed. Atomic power expansion is 5%/year, giving 55000 GWe by 2100. World primary energy increases 2.25%/y, exceeding 4000 EJ/y by 2100. CO2 maximum is roughly 600 ppm-C around year 2085. CO2 declines back below 300 ppm-C by 2145 if the 45-year-delay seawater sink remains effective

  4. Caffeine and D2O medium interact in affecting the expression of radiation-induced potentially lethal damage

    1991-01-01

    Earlier work has been extended to compare the killing of long-phase V79 Chinese hamster cells by ionizing radiation when they are treated immediately after irradiation with medium containing either caffeine or 90% D 2 O. The object was to determine if the enhanced killing due to post-treatment with caffeine, or D 2 O, resulted from action on the same sector of potentially lethal damage as appeared to be the case for hypertonic shock and D 2 O medium. The treatments by themselves were not toxic to unirradiated cells. We found that the enhanced expression of potentially lethal damage by post-treatment with caffeine or D 2 O medium is similar. For example, the kinetic of the repair of the potentially lethal damage expressible by either post-treatment was similar, and an additive enhancement of potentially lethal damage occurred when the two treatments were administered sequentially. These findings suggest that caffeine and D 2 O medium affect the same sector of potentially lethal damage. When the two treatments were combined, however, they competed with each other. Thus, although caffeine and D 2 O medium act on the same sector of potentially lethal damage they do so differently, suggesting that more than one pathway of the expression of radiation damage can result in the same phenotypic effect.

    Muonium (Mu = μ + e - ) is a light analogue of the H-atom. Studies of Mu chemical kinetics have been extended to supercritical water, a medium in some designs of future generation nuclear reactors. The Supercritical-Water-Cooled Reactor (SCWR) would operate at higher temperatures than current pressurized water-cooled reactors, and the lack of knowledge of water radiolysis under supercritical conditions constitutes a technology gap for SCWR development. Accurate modeling of chemistry in a SCWR requires data on kinetics of reactions involved in the radiolysis of water. In this paper, we first review our measurements of kinetics in H 2 O and then describe new data for D 2 O under sub- and supercritical conditions. (author)

    1976-12-01

    Integral reaction rate parameters, intracell thermal neutron flux profiles, and material bucklings were measured for D 2 O-moderated uniform lattices in the exponential facility at the Savannah River Laboratory. Two different slightly enriched coaxial uranium fuel assemblies were examined over a wide range of triangular lattice pitches. Integral parameters are reported for inner and outer fuel separately providing data for a more detailed and rigorous comparison with computation than has been previously available. Results are compared with RAHAB calculations using ENDF/B-IV cross sections. Large discrepancies in agreement between calculation and experiment, outside of experimental errors and uncertainties in the input cross sections, probably result from the resonance capture models used by RAHAB

    Water flow imaging may help to better understand various problems related to water stress of plants. It may help to fully understand the water relations of plants. The objective of this research was to estimate the velocity of water flow in plant samples. Cut roses ( Rosa hybrida, var. 'Milva') were used as samples. Cold neutron radiography (CNR) was conducted at CONRAD, Helmholtz Center Berlin for Materials and Energy, Berlin, Germany. D 2O and H 2O were interchangeably injected into the water feeding system of the sample. After the uptake of D 2O, the neutron transmission increased due to the smaller attenuation coefficient of D 2O compared to H 2O. Replacement of D 2O in the rose peduncle was clearly observed. Three different optical flow algorithms, Block Matching, Horn-Schunck and Lucas-Kanade, were used to calculate the vector of D 2O tracer flow. The quality of sequential images providing sufficient spatial and temporal resolution allowed to estimate flow vector.

    2000-01-01

    1 - Description of program or function: A computer program for the fast computation of the thermodynamic and transport properties of heavy water (D 2 O) at saturation, in subcooled liquid and superheated vapor states. Specific volume (or density), specific enthalpy, specific entropy, constant-pressure specific heat and temperature at saturation are calculated by a number of piecewise continuous approximation functions of (and their derivatives are calculated with respect to) pressure whereas pressure at saturation is calculated by a piecewise continuous approximation function of temperature for heavy water. Density in subcooled liquid state, specific volume in super-heated vapor state, specific enthalpy, specific entropy and constant-pressure specific heat in both of these states are calculated by some piecewise continuous approximation functions of pressure and temperature for heavy water. The correlations used in the calculation of these thermodynamic properties of heavy water were derived by fitting some appropriate curves to the data given in the steam tables by Hill et al (1981). The whole set of correlations and the approximation method used in their derivation are presented by Durmayaz (1997). Dynamic viscosity and thermal conductivity for heavy water are calculated as functions of temperature and density with the correlations given by Hill et al (1981), by Matsunaga and Nagashima (1983) and by Kestin et al (1984). Surface tension for heavy water is calculated as a function of temperature with the correlation given by Crabtree and Siman-Tov (1993). 2 - Methods: A group of pressure-enthalpy (P-h) pairs can be given in an input data file or assigned in the main program without knowing the state in which fluid takes place. In this case, first, the enthalpies at saturation corresponding to the given pressure are computed. Second, the state is determined by comparing the given enthalpy to the saturation enthalpies. Then, the properties are computed. Program D 2 O

    1990-01-01

    The measurement of the thermal conductivity of liquid D 2 O (heavy water) started in 1951. Since then, many researchers have measured the thermal conductivity of heavy water mainly with the aid of steady-state methods such as the parallel plate method and the concentric cylinder method. It should be noted here that even in the case of pure H 2 O or D 2 O enclosed in metallic vessel for a couple of days, the electrical conductivity seems to be not low enough for precise transient hot-wire measurements. The purpose of this paper is to obtain precise thermal conductivity data of liquid D 2 O which can be the reference standard values by the transient hot-wire method. The temperature range covered was 4 degrees C to 80 degrees C with pressure up to 40 MPa and the experimental data have an estimated accuracy of ±0.5%

    Criticality dimensions for highly enriched 235 U (93.5) and 239 Pu (95.5) systems mixed with D 2 O were studied. The objective of this work is to investigate the minimum critical mass and concentration of uranium and plutonium systems in a reflector-moderated arrangement. The present work demonstrates the critical instability of some of these systems that are reflected by D 2 O and expands from previously published and unpublished work. These calculations were performed in a spherical geometry with the DANTSYS codes using the Hansen-Roach cross-section library. Densities examined ranged from normal to very small and are assumed to be uniform throughout the core. These spherical systems are reflected by 100 cm of D 2 O

  13. New theoretical development for the calculating of physical properties of D2O

    International Nuclear Information System (INIS)

    Moreira, Osvaldo

    2011-01-01

    In this work we have developed a new method for calculating the physical properties of heavy water, D 2 O, using the Helmholtz free energy state function, A = U − T S, exclusively for this molecule. The state function has been calculated as ā = ā 0 +ā 1 (specific dimensionless values), where ā 0 is related to the properties of heavy water in gaseous state and ā 1 describes the liquid state. The canonical variables of the state function are absolute temperature and volume. To calculate the physical properties defining absolute pressure and temperature, here a variable change method was developed, based on the solution of a differential equation (function ζ) using numerical algorithms (scaling and Newton-Raphson). Physical quantities calculated are: density ϱ(specific volume υ), specific enthalpy h and entropy s. The results obtained agree completely with the values calculated by the National Institute of Standards and Technology (NIST). In this report it has also proposed an adjustment function to calculate the saturation absolute temperature of heavy water as a function of the pressure: T s (p) = exp[a·b(p)], where a is a vector of constant coefficients and b a vector function of pressure, using theoretical values and extending the wording proposed by the Oak Ridge National Laboratory. The new setting has an error less than 0.03%. (author)

    Angular correlation of annihilation photons were measured for H2O, D2O, 1.74 M PPS/H2O and 1.74 M PPS/D2O solutions of Cl−, Br− and I−. The three components of the angular correlation spectra for D2O and H2O were nearly identical in shape. The positronium (Ps) yields for the H2O and D2O solutions...... before annihilation (lifetime 400 ps) was determined for the three halides in the four solvents. Simple kinetic equations (“trapping model”) with time dependent rate constant, solved analytically, could explain the [X−, e+] formation in H2O fairly well for concentrations below 0.03 M X−, if a diffusion...... controlled reaction with positron diffusion constant D = 5 × 10−5 cm2/s and reaction radius R = 1 nm were assumed. The three halides gave roughly identical [X−, e+] formation below 0.03 M X−. The difference between the four solutions could be explained partly only in terms of viscosity change for the model...

    In this paper, we report vibration-rotation-tunneling levels of the van der Waals clusters N2-H2O and N2-D2O computed from an ab initio potential energy surface. The only dynamical approximation is that the monomers are rigid. We use a symmetry adapted Lanczos algorithm and an uncoupled product basis set. The pattern of the cluster's levels is complicated by splittings caused by H-H exchange tunneling (larger splitting) and N-N exchange tunneling (smaller splitting). An interesting result that emerges from our calculation is that whereas in N2-H2O, the symmetric H-H tunnelling state is below the anti-symmetric H-H tunnelling state for both K = 0 and K = 1, the order is reversed in N2-D2O for K = 1. The only experimental splitting measurements are the D-D exchange tunneling splittings reported by Zhu et al. [J. Chem. Phys. 139, 214309 (2013)] for N2-D2O in the v2 = 1 region of D2O. Due to the inverted order of the split levels, they measure the sum of the K = 0 and K = 1 tunneling splittings, which is in excellent agreement with our calculated result. Other splittings we predict, in particular those of N2-H2O, may guide future experiments.

    The cooperative Thomson scattering method is one of the various new techniques proposed for measuring the temperature of ions in nuclear fusion critical plasma, for which a high-performance FIR laser pumped by an injection-locked CO 2 laser is required. This report deals with D 2 O laser with a wavelength of 385 μm which is pumped by injection-locked single-mole TEA CO 2 laser composed of a driver laser and an output-stage laser. A small-sized automatic pre-ionization type laser is employed for the driver. The resonator of the driver laser consists of a plane grating of littrow arrangement and ZnSe plane output mirrors with reflection factor of 50 %. An aperture and ZnSe etalon are inserted in the resonator to produce single transverse- and longitudinal-mode oscillation, respectively. The output-stage laser is also of the automatic pre-ionization type. Theoretically, an injection power of 0.1 pW/mm 3 is required for a CO 2 laser. Single-mode oscillation of several hundred nW/mm 3 can be produced by the CO 2 laser used in this study. Tuning of the output-stage laser is easily controlled by the driver laser. High stability of the injection-locked operation is demonstrated. CO 2 laser beam is introduced into the D 2 O laser through a KCl window to excite D 2 O laser beam in the axial direction. Input and output characteristics of the D 2 O laser are shown. Also presented are typical pulse shapes from the D 2 O laser pumped by a free-running CO 2 laser pulse or by an injection-locked single-mode CO 2 laser pulse. (Nogami, K.)

    We present a low-temperature and high-pressure ultrasonic study of elastic properties of isotopic H2O-D2O solid solutions, comparing their properties with those of the isotopically pure H2O and D2O ices. Measurements were carried out for solid state amorphization (SSA) from 1h to high-density amorphous (HDA) ice upon compression up to 1.8 GPa at 77 K and for the temperature-induced (77 -190 K ) u-HDA (unrelaxed HDA) → e-HDA (expanded HDA) → low-density amorphous (LDA )→1 c cascade of ice transformations near room pressure. There are many similarities in the elasticity behaviour of H2O ,D2O , and H2O-D2O solid solutions, including the softening of the shear elastic modulus as a precursor of SSA and the HDA →LDA transition. We have found significant isotopic effects during H/D substitution, including elastic softening of H2O -D2O solid solutions with respect to the isotopically pure ices in the case of the bulk moduli of ices 1c and 1h and for both bulk and shear elastic moduli of HDA ice at high pressures (>1 GPa ) . This softening is related to the configurational isotopic disorder in the solid solutions. At low pressures, the isotope concentration dependence of the elastic moduli of u-HDA ice changes remarkably and becomes monotonic with pronounced change of the bulk modulus (≈20 %) .

    The behavior of D 2O ice on CO/Pt(1 1 1) and Pt(1 1 1) under the irradiation of near-IR pulses (NIR) was studied by sum-frequency generation (SFG) spectroscopy. The peaks assigned to the O-D stretching modes of ice were obtained for the first 30 molecular layers on Pt(1 1 1). When the D2O/ CO/ Pt(1 1 1) was irradiated, the signal of D 2O was weakened after 500 ps, but that of CO was weakened immediately after the pumping. A similar time response was observed for the D 2O peak in D2O/ Pt(1 1 1) . The weakening of SFG is attributed to the broadening of bands due to thermal excitation. This indicates that the energy of the pump pulse is deposited on the Pt(1 1 1) surface and diffused into the layers of D 2O ice in the 500 ps timescale.

    The in situ observation of the absorption of deuterium (or hydrogen) into the Pd cathode during D 2 O (or H 2 O) electrolysis was made by an electrochemical microbalance technique which is based on the quartz-crystal electrode. The resonant frequency of the Pd-coated quartz-crystal electrode decreased with increasing amount of charge passed during electrolysis, and the frequency change for the D 2 O electrolysis was about twice that for the H 2 O electrolysis. The atom ratios of H/Pd and D/Pd of the H-Pd and D-Pd compounds resulting from the electrolysis were estimated to be 0.59 and 0.57, respectively. (author)

    The thermal conductivities of H 2 O and D 2 O vapors were measured in a modified thick hot wire cell between 358 and 386 K at pressures ranging from 100 to 1000 Torr. Analysis of the data indicates that molecular association to form a dimeric species is the main source of enhancement of the thermal conductivity of both vapors. The enthalpy and entropy of association of the H 2 O dimer are -3.59 kcal mol -1 and -18.59 cal deg -1 mol -1 , respectively. The enthalpy and entropy of association of the D 2 O dimer are -3.66 kcal mol -1 and -18.67 cal deg -1 mol -1 , respectively. The measured enthalpy of association of the H 2 O dimer is in agreement with recently reported ab initio molecular orbital calculations on the H 2 O dimer. The entropies of association of the H 2 O and D 2 O dimers are calculated theoretically and are found to be in agreement with the measured values

    In diverse environments on a global scale cyanobacteria are important primary producers of organic matter. Moreover, while mechanisms of CO_2 fixation are well understood, the distribution of the flow of fixed organic carbon within individual cells and complex microbial communities is less well characterized. To obtain a general overview of metabolism, we describe the use of deuterium oxide (D_2O) to measure deuterium incorporation into the intracellular metabolites of two physiologically diverse cyanobacteria: a terrestrial filamentous strain (Microcoleus vaginatus PCC 9802) and a euryhaline unicellular strain (Synechococcus sp. PCC 7002). D_2O was added to the growth medium during different phases of the diel cycle. Incorporation of deuterium into metabolites at nonlabile positions, an indicator of metabolite turnover, was assessed using liquid chromatography mass spectrometry. Expectedly, large differences in turnover among metabolites were observed. Some metabolites, such as fatty acids, did not show significant turnover over 12–24 h time periods but did turn over during longer time periods. Unexpectedly, metabolites commonly regarded to act as compatible solutes, including glutamate, glucosylglycerol, and a dihexose, showed extensive turnover compared to most other metabolites already after 12 h, but only during the light phase in the cycle. We observed extensive turnover and found it surprising considering the conventional view on compatible solutes as biosynthetic end points given the relatively slow growth and constant osmotic conditions. Our suggests the possibility of a metabolic sink for some compatible solutes (e.g., into glycogen) that allows for rapid modulation of intracellular osmolarity. To investigate this, uniformly "1"3C-labeled Synechococcus sp. PCC 7002 were exposed to "1"2C glucosylglycerol. Following metabolite extraction, amylase treatment of methanol-insoluble polymers revealed "1"2C labeling of glycogen. Overall, our work shows that D_2

    Sliding cell method, developed in our laboratory, has been used to measure the inter diffusion coefficient of thallium ion in thallous sulphate solution over a wide concentration range using both water and heavy water as solvent at 35degC. The results have been analysed from the point of view of both ion-ion and ion-solvent interactions. The comparison of the diffusivities of the same ion in D 2 O and H 2 O electrolyte solutions at the same temperature indicate that the addition of salt affects the two solvent differently.

    Neutron and x-ray powder diffraction have been used to investigate the crystal structures of a sample of the newly-discovered superconducting sodium cobaltate deuterate compound with composition Na0.31(3)CoO2ṡ1.25(2)D2O and its anhydrous parent compound Na0.61(1)CoO2. The anhydrous parent compound Na0.61(1)CoO2 has two partially occupied Na sites sandwiched, in the same plane, between CoO2 layers. When Na is removed to make the superconducting composition, the Na site that experiences the strongest Na Co repulsion is emptied while the occupancy of the other Na site is reduced to about one third. The deuterate superconducting compound is formed by coordinating four D2O molecules (two above and two below) to each remaining Na ion in a way that gives Na O distances nearly equal to those in the parent compound. One deuteron of the D2O molecule is hydrogen bonded to an oxygen atom in the CoO2 plane and the oxygen atom and the second deuteron of each D2O molecule lie approximately in a plane between the Na layer and the CoO2 layers. This coordination of Na by four D2O molecules leads in a straightforward way to ordering of the Na ions and D2O molecules consistent with the observation of additional shorter-range scattering features in the diffraction data. The sample studied here, which has Tc=4.5 K, has a refined composition of Na0.31(3)CoO2ṡ1.25(2)D2O, in agreement with the expected 1:4 ratio of Na to D2O. These results show that the optimal superconducting composition should be viewed as a specific hydrated compound, not a solid solution of Na and D2O (H2O) in NaxCoO2ṡD2O. The hydrated superconducting compound may be stable over a limited range of Na and D2O concentration, but studies of Tc and other physical properties vs Na or D2O composition should be viewed with caution until it is verified that the compound remains in the same phase over the composition range of the study.

    Low energy ions were produced by N 2 glow-discharge. The positive ones were accelerated into ethanol solution with D 2 O as solvent to induce chemical reactions. GC-MS analysis showed that DCH 2 CH 2 OH, HOCH 2 CH 2 OD were produced by such kind of implantation. Thus, it was proved that the reaction was mainly caused by radicals generated by decomposition of water molecules, D . and . OD played an important role in the process. Meanwhile, CH 3 COOD and HOCH 2 CH 2 ND 2 were also found in the products, so it was concluded that the reaction was carried out under an oxidative atmosphere, which was thought to be probably related to . OD radicals, too. The capture of D from D 2 O by N + to form . ND 2 radicals was not only an initial step to produce HOCH 2 CH 2 ND 2 but also served as a probable pattern for 'nitrogen deposition'. All these were helpful to reveal the mechanism of the reaction induced by low energy N + implanting into solution samples

  14. Theoretical Time Dependent Thermal Neutron Spectra and Reaction Rates in H2O and D2O

    Purohit, S.N.

    1966-04-01

    The early theoretical and experimental time dependent neutron thermalization studies were limited to the study of the transient spectrum in the diffusion period. The recent experimental measurements of the time dependent thermal neutron spectra and reaction rates, for a number of moderators, have generated considerable interest in the study of the time dependent Boltzmann equation. In this paper we present detailed results for the time dependent spectra and the reaction rates for resonance detectors using several scattering models of H 2 O and D 2 O. This study has been undertaken in order to interpret the integral time dependent neutron thermalization experiments in liquid moderators which have been performed at the AB Atomenergi. The proton gas and the deuteron gas models are inadequate to explain the measured reaction rates in H 2 O and D 2 O. The bound models of Nelkin for H 2 O and of Butler for D 2 O give much better agreement with the experimental results than the gas models. Nevertheless, some disagreement between theoretical and experimental results still persists. This study also indicates that the bound model of Butler and the effective mass 3. 6 gas model of Brown and St. John give almost identical reaction rates. It is also surprising to note that the calculated reaction rate for Cd for the Butler model appears to be in better agreement with the experimental results of D 2 O than of the Nelkin model with H 2 O experiments. The present reaction rate studies are sensitive enough so as to distinguish between the gas model and the bound model of a moderator. However, to investigate the details of a scattering law (such as the effect of the hindered rotations in H 2 O and D 2 O and the weights of different dynamical modes) with the help of these studies would require further theoretical as well as experimental investigations. Theoretical results can be further improved by improving the source for thermal neutrons, the group structure and the scattering

    Heavy water vapor release experiments were carried out in a greenhouse using deuterium as a substitute for tritium and uptake and loss kinetics of D 2 O in leaves and formation, translocation and retention of organically bound deuterium (OBD) in bean soybean exposed to D 2 O under different growth phase were investigated. Rate constants of D 2 O uptake in leaves of soybean in the daytime release were 0.6 - 6.1 hr -1 and several times higher than those in the nighttime release. Rate constants of D 2 O loss in leaves after daytime release were almost the same as those after the nighttime release. No significant difference in the half time of D 2 O loss was observed between daytime and nighttime releases. After D 2 O release, OBD concentration in bean in daytime experiments increased with time until 3 - 4 days of the experiments and then decreased with time. The OBD concentrations in bean in daytime release were several times higher than those in nighttime release while the extents of decrease of OBD concentration were somewhat lower than those in the daytime experiment.

    The infrared absorption spectra of D2O monomers and clusters isolated in rare-gas matrices were systematically reinvestigated under the control of the following factors: the D2O concentration, deposition rate, heating temperature, and rare-gas species. We clearly show that the cluster-size distribution is dependent on not only the D2O concentration but also the deposition rate of a sample; as the rate got higher, smaller clusters were preferentially formed. Under the heating procedures at different temperatures, the cluster-size growth was successfully observed. Since the monomer diffusion was not enough to balance the changes in the column densities of the clusters, the dimer diffusion was likely to contribute the cluster growth. The frequencies of the bonded-OD stretches of (D2O)k with k = 2-6 were almost linearly correlated with the square root of the critical temperature of the matrix material. Additional absorption peaks of (D2O)2 and (D2O)3 in a Xe matrix were assigned to the species trapped in tight accommodation sites.

    The Savannah River Laboratory LTRIIA slightly-enriched uranium-D 2 O critical experiment was analyzed with ENDF/B-IV data and the RCP01 Monte Carlo program, which modeled the entire assembly in explicit detail. The integral parameters delta 25 and delta 28 showed good agreement with experiment. However, calculated K/sub eff/ was 2 to 3% low, due primarily to an overprediction of U238 capture. This is consistent with results obtained in similar analyses of the H 2 O-moderated TRX critical experiments. In comparisons with the VIM and MCNP2 Monte Carlo programs, good agreement was observed for calculated reeaction rates in the B 2 =0 cell

    We focus this work on the measurement of the possible Deuterium - Deuterium reaction in a SCBL (Single Cavitation Bubble Luminescence) system.We measure the possible reaction at the bubble generation time and at the bubble collapse time. We use a Nd:YAG laser and CDCl 3 and D 2 O as a medium to generate the bubble. Since CDCl 3 accommodation coefficient is best than that of D 2 O, it is expected a greater collapse force than using D 2 O.To benefit the bubble collapse violence, we diminish the temperature of the liquids.To avoid false neutron detection, we developed a measuring system with high background reject using the characteristic experiment times.No neutrons attributable to Deuterium - Deuterium fusion reaction were measured

    The barotropic behavior of D 2 O dispersions of 1-stearoyl-2-caproyl-sn-glycero-3-phosphocholine, C(18):C(10)PC, a highly asymmetric phospholipid in which the length of the fully extended acyl chain at the sn-1 position of the glycerol backbone is twice as long as that at the sn-2 position, has been investigated by high-pressure Fourier transform infrared spectroscopy. This asymmetric phosphatidylcholine bilayer at room temperature displays a pressure-induced phase transition corresponding to the liquid-crystalline----gel phase transition at 1.4 kbar. A conformational ordering of the lipid acyl chains is observed to take place abruptly at the transition pressure of 1.4 kbar. However, the lamellar lipid molecules and their acyl chains remain to be orientationally disordered in the gel phase until the applied pressure reaches 5.5 kbar. In the gel phase of fully hydrated C(18):C(10)PC, the asymmetric lipid molecules assemble into mixed interdigitated bilayers with perpendicular orientation of the zigzag planes among neighboring acyl chains. The role of excess water played in the interchain structure and the behavior of excess water and bound water under high pressure are also discussed

    A forwardly-peaked bright neutron source was produced using a laser-driven, deuteron-rich ion beam in a pitcher-catcher scenario. A proton-free ion source was produced via target normal sheath acceleration from Au foils having a thin layer of D2O ice at the rear side, irradiated by sub-petawatt laser pulses (˜200 J, ˜750 fs) at peak intensity ˜ 2× {10}20 {{W}} {{cm}}-2. The neutrons were preferentially produced in a beam of ˜70° FWHM cone along the ion beam forward direction, with maximum energy up to ˜40 MeV and a peak flux along the axis ˜ 2× {10}9 {{n}} {{sr}}-1 for neutron energy above 2.5 MeV. The experimental data is in good agreement with the simulations carried out for the d(d,n)3He reaction using the deuteron beam produced by the ice-layered target.

    The thirteenth Personnel Dosimetry Intercomparison Study (i.e., PDIS 13) was conducted during April 1987 as a joint effort by Oak Ridge National Laboratory's (ORNL) Dosimetry Applications Research Group and the Southwest Radiation Calibration Center at the University of Arkansas. A total of 48 organizations (34 from the US and 14 from abroad) participated in PDIS 13. Participants submitted a total of 1,113 neutron and gamma dosimeters for this mixed field study. The dosimeters were transferred by mail and were handled by experimental personnel at ORNL and the University of Arkansas. The type of neutron dosimeter and the percentage of participants submitting that type are as follows: TLD-albedo (49%), direct interaction TLD (31%), CR-39 (17%), film (3%). The type of gamma dosimeter and the percentage of participants submitting that type are as follows: Li 2 B 4 O 7 , alone or in combination with CaSO 4 , (69%), 7 LiF (28%), natural LiF (3%). Radiation exposures in PDIS 13 were limited to 0.5 and 1.5 mSv from 252 Cf moderated by 15-cm of D 2 O. Traditional exposures using the Health Physics Research Reactor (HPRR) were not possible due to the fact that all reactors at ORNL, including the HPRR, were shutdown by order of the Department of Energy at the time the intercomparison was performed. Planned exposures using a 238 PuBe source were negated by a faulty timing mechanism. Based on accuracy and precision, direct interaction TLD dosimeters exhibited the best performance in PDIS 13 neutron measurements. They were followed, in order of best performance, by CR-39, TLD albedo, and film. The Li 2 B 4 O 7 type TLD dosimeters exhibited the best performance in PDIS 13 gamma measurements. They were followed by natural LiF, 7 LiF, and film. 12 refs., 1 fig., 5 tabs

    Experiments on phase diagrams and critical opalescence of a fluid mixture, isobutyric acid in D 2 O, indicate that the presence of isotope exchange reactions can change the critical behavior of such a system from that of a simple binary fluid mixture. Appreciable amounts of additional species due to isotope exchange distort the coexistence curve, shift the critical solution concentration y/sub c/ away from the concentration (y/sub I/*) where the maximal phase separation temperature T/sub p/,max occurs, and make the critical exponents γ and ν in the one-phase region (T>T/sub c/) different from those of the coexisting two-phase region (T 0 C differing from y/sub I/*=0.310 at T/sub p/,max=45.11 0 C. In the one-phase region, γ=1.25, ν=0.633, and xi 0 =3.13 A, in excellent agreement with γ=1.24 and ν=0.633 of simple fluid systems. However, in the coexisting two-phase region, the critical exponents appear to be renormalized with γ/sub x/ =1.39, ν/sub x/approx. =0.76, and xi 0 approx. =0.6 A. These results are in agreement with the renormalized critical exponents γ/sub x/=1.40 +- 0.02 and ν/sub x/ =0.73 +- 0.04 near the plait point of a ternary liquid mixture: ethanol--water--chloroform

  5. The influence of D2O, perchlorate, and variation in temperature on the potential-dependent contractile function of frog skeletal muscle

    1985-01-01

    D 2 O and perchlorate manifest opposing effects on the contractile function of skeletal muscle (amplitude of twitches and maximum K contractures, potential dependence of contraction and inactivation), and when combined the influence of one may effectively antagonize that of the other. The ratio of perchlorate concentrations required to produce effects of equal intensity, (e.g., twitch enhancement and restoration of maximum K contractures in media lacking divalent cations or containing a depressant concentration of a cationic amphipath) in H 2 O and D 2 O solutions was generally rather constant. These findings are compatible with the view that both agents can influence contractile function by virtue of their effects on solvent structure. In the absence of divalent cations, the effects of reduced temperature resemble those of D 2 O whereas the effects of increased temperature resemble those of the chaotropic anion. However, in other media, variation in temperature was found to result in additional nonsolvent effects so that low temperature could oppose rather than enhance the effects of D 2 O. These observations are discussed in terms of a model which postulates a role for solvent influences on the kinetics of two separate potential-dependent conformational transitions of membrane proteins which mediate the activation and inactivation of contraction in skeletal muscle

    Full Text Available Thermostabilizing effect of heavy water (D2O or deuterium oxide has been demonstrated previously on several enzymes and vaccines like oral poliovirus vaccine and influenza virus vaccine. In view of the above observations, effect of heavy water on in situ thermostabilization of recombinant p26 protein on enzyme-linked immunosorbent assay (ELISA for serodiagnosis of equine infectious anemia virus (EIAV infection was investigated in the present study. The carbonate-bicarbonate coating buffer was prepared in 60% and 80% D2O for coating the p26 protein in 96-well ELISA plate and thermal stability was examined at 4°C, 37°C, 42°C, and 45°C over a storage time from 2 weeks to 10 months. A set of positive serum (n=12 consisting of strong, medium, and weak titer strength (4 samples in each category and negative serum (n=30 were assessed in ELISA during the study period. At each time point, ELISA results were compared with fresh plate to assess thermal protective effect of D2O. Gradual increase in the stabilizing effect of 80% D2O at elevated temperature (37°C < 42°C < 45°C was observed. The 80% D2O provides the thermal protection to rp26 protein in ELISA plate up to 2 months of incubation at 45°C. The findings of the present study have the future implication of adopting cost effective strategies for generating more heat tolerable ELISA reagents with extended shelf life.

    2008-01-01

    Thermo luminescence (TL) characteristics of rice flour are studied in the temperature range of 77 to 200K with and with out H 2 O and D 2 O. The TL is recorded for the virgin samples and also on irradiation of the same by exposing it to X-ray at 77K. The low temperature TL of X-ray irradiated two rice varieties Basmati and Gujarat-77 are discussed in this paper. The two varieties are given as X-ray dose of 1kGy. The TL is recorded for 200 mg rice powder, 200 mg rice powder + 0.5 cc of DM water, 200 mg rice powder + 0.5 cc of heavy water. The TL displayed for the 1kGy X-ray dose samples is around 113K with a broad shoulder around 153K. After adding DM water or heavy water as many as three new peaks are emerged. One main point to be noted is that the effect of water and heavy water on the specimens led to three more peaks one may be hump but the generation of 107K peak is interesting. The peak observed around 173K can be attributed to water and heavy water. The hump around 163K is the peak associated with rice. But the generation of other two peaks around 156K and 108K are to be analysed. It is also interesting to note that the 108K peak resolves well in water than that of heavy water. The initial results are interesting in nature. However the rice powder consists of many varieties of organic chemical constituents. Possible conclusions are drawn on comparing with the available literature on low temperature TL of rice powder. However, to pin point which chemical constituent of rice powder is absorbing/reacting with the added water and heavy water leads new LTTL peaks is very difficult at this stage. Table-1 is the LTTL peak temperatures and intensity of the studied samples. (author)

    Effects of deuterium oxide (D 2 O) and 3-aminobenzamide, an inhibitor of poly(ADP-ribose) synthetase, on cell proliferation and survival were studied in cultured mammalian L5178Y cells under growing conditions and after acute and low-dose-rate irradiation at about 0.1 to 0.4 Gy/hr of γ rays. Growth of irradiated and unirradiated cells was inhibited by 45% D 2 O but not by 3-aminobenzamide at 10mM, except for treatments longer than 30 hr. The presence of these agents either alone or in combination during irradiation at low dose rates suppressed almost totally the decrease in cell killing due to the decrease in dose rate. Among other inhibitors tested, theobromine and theophylline were found to be effective in eliminating the dose-rate effects of γ rays. Possible mechanisms underlying the inhibition are discussed

    2005-01-01

    We report measurements of low-energy electron stimulated desorption of D - , O - and OD - anions from multilayer amorphous D 2 O films physisorbed on a Pt substrate. The 0-20 eV incident energy dependence (i.e., the yield function) of the desorbed D - yield reveals the presence of a strong peak located at 7.2 eV with a shoulder near 9 eV, which are due to dissociation of the transient states 2 B 1 and 2 A 1 of D 2 O, respectively. The O - and OD - yield functions each exhibit a single broad structure between 5 and 12 eV which also result from dissociative electron attachment (DEA). Due to the weakness of the O - and OD - signals, three possible processes involving DEA must be considered to explain their yield functions, i.e., direct DEA, reactive scattering and DEA to a new product in the film synthesized by the electron beam. It is concluded that at large electron doses (>7.5x10 14 electrons/cm 2 ), these broad peaks arise from DEA to a new product, whereas at lower dose the possibility of direct DEA (i.e., e - +D 2 O→D 2 O - →O - +D 2 and OD - +D) cannot be entirely discounted. Above 15 eV, all anion yield functions exhibit a monotonic rise due to direct dipolar dissociation

    Schiff base formation between pyridoxal 5'-phosphate (PLP) and 2-amino-3-phosphonopropionic acid (APP) has been investigated by measurement of the corresponding NMR and electronic absorption spectra. A value of 0.26 was found for the formation constant of the completely deprotonated Schiff base species, and is much smaller than the values reported for pyridoxal-β-chloroalanine and pyridoxal-O-phosphoserine. The protonation constants for the aldehyde and hydrate forms of PLP were determined in D 2 O by measurement of the variation of chemical shifts with pD (pH in D 2 O). The hydration constants of PLP were determined in a pD range 2-12, and species distributions were calculated. The protonation constants of the APP-PLP Schiff base determined by NMR in D 2 O were found to have the log values 12.54, 8.10, 6.70, and 5.95, and the species distributions were calculated for a range of pD values. Evidence is reported for hydrogen bonding involving the phosphate and phosphonate groups of the diprotonated Schiff base. The cis and trans forms of the Schiff bases were distinguished with the aid of the nuclear Overhauser effect. 43 references, 9 figures, 3 tables

    In this study, continuous in-source hydrogen/deuterium exchange (HDX) atmospheric pressure photoionization (APPI) mass spectrometry (MS) with continuous feeding of D 2 O was developed and validated. D 2 O was continuously fed using a capillary line placed on the center of a metal plate positioned between the UV lamp and nebulizer. The proposed system overcomes the limitations of previously reported APPI HDX-MS approaches where deuterated solvents were premixed with sample solutions before ionization. This is particularly important for APPI because solvent composition can greatly influence ionization efficiency as well as the solubility of analytes. The experimental parameters for APPI HDX-MS with continuous feeding of D 2 O were optimized, and the optimized conditions were applied for the analysis of nitrogen-, oxygen-, and sulfur-containing compounds. The developed method was also applied for the analysis of the polar fraction of a petroleum sample. Thus, the data presented in this study clearly show that the proposed HDX approach can serve as an effective analytical tool for the structural analysis of complex mixtures. Graphical abstract ᅟ.

  19. Effect of hydration on the amide I band in the binary solvents dioxane-D2O and dioxane-H2O

    Kobayashi, M.; Kobayashi, M.

    1980-01-01

    Hydration of amides in aqueous solutions has been studied by measuring the infrared spectra of amides (benzamide, p-methoxybenzamide, and ropionamide) in dioxane-D 2 O and dioxane-H 2 O mixtures. The absorption due to the C=O stretching (or amide I band) exhibited a very remarkable red shift accompanied by a characteristic change of the band shape as the water content in the medium increased. The spectral change is attributed to the change of the hydration state at the carbonyl oxygen. In the aqueous mixtures, amide molecules participate in an equilibrium among various states of hydration. The weighted mean frequency of the ν/sub C = O/ absorption, anti ν/sub C = O/, varied in proportion to the water contained in the medium. The difference between the anti ν/sub C = O/ value in pure water and that in pure dioxane,Δ anti ν, was used as a measure of the maximum degree of hydration. It was larger for propionamide than for the aromatic amides, suggesting that the steric effect of the substituents is of major importance in hydration. The isotope effect, Δ anti ν/sub D 2 O//Δ anti ν/sub H 2 O/, in the range from 1.4 to 1.6 for all cases examined, indicated that stronger hydration of amides occurred with D 2 O than with H 2 O

    1700-nm window has been demonstrated to be a promising excitation window for deep-tissue multiphoton microscopy (MPM). Long working-distance water immersion objective lenses are typically used for deep-tissue imaging. However, absorption due to immersion water at 1700 nm is still high and leads to dramatic decrease in signals. In this paper, we demonstrate measurement of absorption spectrum of deuterium oxide (D 2 O) from 1200 nm to 2600 nm, covering the three low water-absorption windows potentially applicable for deep-tissue imaging (1300 nm, 1700 nm, and 2200 nm). We apply this measured result to signal enhancement in MPM at the 1700-nm window. Compared with water immersion, D 2 O immersion enhances signal levels in second-harmonic generation imaging, 3-photon fluorescence imaging, and third-harmonic generation imaging by 8.1, 24.8, and 24.7 times with 1662-nm excitation, in good agreement with theoretical calculation based on our absorption measurement. This suggests D 2 O a promising immersion medium for deep-tissue imaging

  5. Effect of buffer general acid-base catalysis on the stereoselectivity of ester and thioester H/D exchange in D2O.

    As part of a comprehensive investigation on the stereochemistry of base-catalyzed 1,2-elimination and H/D exchange reactions of carbonyl compounds, we have found that the stereoselectivity of H/D exchange of 3-hydroxybutyryl N-acetylcysteamine (3) in D(2)O is strongly influenced by the presence of buffers. This buffer effect is also operative with a simple acyclic ester, ethyl 3-methoxybutanoate (7). Buffers whose general-acid components are cyclic tertiary ammonium ions are particularly effective in changing the stereoselectivity. (2)H NMR analysis showed that without buffer, H/D exchange of 3 produces 81-82% of the 2R*, 3R* diastereomer of 2-deuterio 3 (the anti product). In the presence of 0.33 M 3-quinuclidinone buffer, only 44% of the 2R*, 3R* diastereomer was formed. With ester 7, the stereoselectivity went from 93-94% in DO(-)/D(2)O to 60% in the presence of buffer. Phosphate buffer, as well as others, also showed substantial effects. The results are put into the context of what is known about the mechanism of H/D exchange of esters and thioesters, and the relevance of the buffer effect on the mechanism of the enoyl-CoA hydratase reaction is discussed. It is likely that hydrogen bonding in the enolate-buffer acid encounter complex is an important stereochemical determinant in producing a greater amount of the 2R*, 3S* diastereomer (the syn product). Studies that involve the protonation of enolate anions in D(2)O need to include the buffer general acid in any understanding of the stereoselectivity. © 2011 American Chemical Society

    The exchange reaction between central ions in the NdD - Ln' 3+ systems, where Ln' 3+ is a substituting cation (Eu 3+ and Ho 3+ , D 4 =cyclohexanediaminetetraacetate) is studied and the electrophilic suhstitution mechanism is considered. To study the kinetic isotope effects, the reagents have been solVed in heavy water containing 99.9% D 2 O. The electrophilic substitution in the indicated systems proceeds through the dissociative mechanism catalyzed by protons and via the spontaneous dissociation mechanism. The exchange via the acid-catalyzed mechanism is limited by the intermediate protonated complex decay. The associative mechanism of the electrophilic exchange in the studied systems is not realized

    Buckling determinations by means of flux mapping were performed in TZ up to 250 deg C on two lattices of Aagesta fuel assemblies in D 2 O and on D 2 O alone. Most of the flux measurements were made with fission counters in pressure thimbles. The perturbations caused by the thimbles were studied experimentally in various ways and compared with two group diffusion-theory calculations. In one of the lattices the effectiveness of a control rod (AglnCd) was also investigated. The results of the diffusion length experiments indicated some systematic error of the order of 0.15 - 0.10/m 2 in the bucklings measured, though the temperature dependence should be well established. The bucklings of the two lattices studied (square pitches 24 and 27 cm) were found to be less sensitive to temperature than theoretical calculations predict, the temperature coefficient being more than 10 per cent smaller. The buckling changes from 20 to 250 deg C were about -2.4 and -1.8/m 2 , respectively, for the two lattices. During part of the experimental period we had, for some unexplained reason, about 30 per cent excess absorption in the heavy water

    We present experimental evidence for a quantum phase transition in the easy-axis S = 3/2 anisotropic quasione-dimensional ferromagnet CoCl2 · 2D2O in a transverse field. Elastic neutron scattering shows that the magnetic order parameter vanishes at a transverse critical field μ0Hc = 16.05(4) T......, while inelastic neutron scattering shows that the gap in the magnetic excitation spectrum vanishes at the same field value, and reopens for H>Hc. The field dependence of the order parameter and the gap are well described by critical exponents β = 0.45 ± 0.09 and zν close to 1/2, implying...... that the quantum phase transition in CoCl2 · 2D2O differs significantly from the textbook version of a S = 1/2 Ising chain in a transverse field. We attribute the difference to weak but finite three-dimensionality of the magnetic interactions....

    Betaine fosfate (CH 3 ) 3 N + CH 2 COO - .H 3 PO 4 modification by using D 2 O has been studied. This modification was carried out by slowly evaporation the saturated Betaine phosphat in the D 2 O solution in the dry box at 40 o C, until the dry crystal were formed. Based on the NMR data, can be concluded that the exchange process with D has been runed well and Betaine phosphate-D (CH 3 ) 3 N + CH 2 COO - .H 3 PO 4 has been resulted. From the X-ray diffraction pattern data can be concluded that there are a deference in the crystal structure between Betaine phosphate and Betaine phosphate modification result. From the Differential Scanning Colorimeter (DSC) diagram at the range temperature from 30 o C to 250 o C, can be shown that the Betaine phosphate-H has two endothermic transition phase, at 99 o C with a very little adsorbed calor and at 221.50 o C with -26.75 cal/g. Modified Betaine phosphate has also two endothermic transition phase, at 99.86 o C with -1.94 cal/g and at 171.01 o C with -3.48 cal/g. It can be conclosed that the D atom substitution on the H atoms in Betaine phosphate, to change the crystal and the endothermic fase temperature and energy

    Temperature programmed desorption (TPD) was used to study surface reactions of Fe 3O 4(1 1 1)-(2 × 2) sequentially exposed, at ˜100 K, to vapor-phase D 2O and CCl 4. Previous TPD and XPS results have indicated that in the absence of D 2O, CCl 4 dissociatively adsorbs on Fe 3O 4(1 1 1) producing chemisorbed Cl and CCl 2. Subsequent heating of the surface results in abstraction of lattice iron and oxygen atoms and causes them to desorb as FeCl 2 and OCCl 2, respectively. This study shows that when this Fe 3O 4 surface is exposed only to D 2O, TPD measures a rich surface chemistry with multiple desorption events extending as high as ˜800 K, indicating dissociative adsorption of D 2O on the Fe 3O 4(1 1 1) surface. After sequential exposure to D 2O and then CCl 4, the production of FeCl 2 and OCCl 2 from adsorbed CCl 4 is suppressed, indicating that D 2O fragments block the surface reactive sites.

    This paper provides an overview of the neutronic performance of an idealized research reactor using several high density LEU fuels that are being developed by the RERTR program. High-density LEU dispersion fuels are needed for new and existing high-performance research reactors and to extend the lifetime of fuel elements in other research reactors. This paper discusses the anticipated neutronic behavior of proposed advanced fuels containing dispersions of U 3 Si 2 , UN, U 2 Mo and several uranium alloys with Mo, or Zr and Nb. These advanced fuels are ranked based on the results of equilibrium depletion calculations for a simplified reactor model having a small H 2 O-cooled core and a D 2 O reflector. Plans have been developed to fabricate and irradiate several uranium alloy dispersion fuels in order to test their stability and compatibility with the matrix material and to establish practical loading limits

Excess partial molar free energies, enthalpies, and entropies for the solvent and their isotope effects were calculated from the temperature derivatives of the osmotic coefficients. New partial molar volume data are reported at 25 C at low and intermediate concentrations. The thermodynamic properties of solution are compared with those of urea and discussed using the cage model of hydrophobic hydration. The results support the mixed (polar-apolar) character of this compound and show that its structural effect on water changes with temperature and concentration

    Full Text Available Teknik jahit celup biasa dikenal dengan istilah tritik, yang berarti titik, merupakan teknik tekstil kelompok celup rintang. Tritik adalah cara menghias kain putih dengan menjahit jelujur lalu ditarik kemudian dicelup dan motif terbentuk setelah benang dilepaskan. Teknik tritik digunakan untuk membuat kain sasirangan, kain tradisional Kalimantan Selatan, Indonesia. Proses menjahit pada tritik dikerjakan secara tradisional tanpa ketentuan yang jelas, sehingga pengembangan desain motif belum maksimal. Melihat kondisi tersebut, penelitian  ini menggunakan pola geometris pada teknik tritik untuk melihat kemungkinan dihasilkan motif berbeda. Dengan  metode eksperimen kualitatif didapat ketentuan mengenai aturan jahitan yang diaplikasikan pada pembuatan pola geometris. Penggunaan pola geometris menghasilkan motif lebih teratur dengan tetap terkesan samar sebagai ciri khas tritik. Pewarnaan bertahap dan pengaturan jarak menghasilkan efek ilusi optik (kedalaman, arah, dan gerak.

Tritik is a method to embellish white cloth by tacking, which is then dyed and removed. The motif is formed after the thread is removed. Tritik methods and techniques are less popular compared to batik or dyed ikat. It is, however, used in making sasirangan cloth, a traditional cloth from South Kalimantan, Indonesia. The stitching has always been done traditionally due to the lack of clear convention on stitching as a resist-media. Thus, development of motif designs is not in full capacity. Taking into consideration the above, this study is carried out to create new geometric patterns using tritik techniques. Qualitative experiment methods are used to obtain ideal stitching

  3. Total scattering cross-sections for the systems nH2 + nH2, pH2 + pH2, nD2 + nD2, oD2 + oD2 and HD + HD for relative energies below ten milli-electron volts

    Relative total scattering cross sections for nH 2 + nH 2 , pH 2 + pH 2 , nD 2 + nD 2 , oD 2 + oD 2 , and HD + HD were measured with inclined nozzle beams derived from nozzle sources and intersecting at 21 0 . Both nozzles could be varied in temperature from 4.2K to 300K to provide the velocity range for the cross sections. The use of a parahydrogen converter allowed the measurement of the pH 2 + pH 2 and oD 2 + oD 2 cross sections. Cross sections for the H 2 + H 2 were measured over a relative velocity range of 200 m/s to 1450 m/s. The nH 2 + nH 2 results show an undulation in the velocity range between 350 m/s and 400 m/s that corresponds to a l = 3 orbiting resonance. Analysis of the pH 2 + pH 2 cross section indicates a l = 4 orbiting resonance near 586 m/s. This resonance has a peak energy of 1.79 meV and a measured energy width of 1.05 meV, both which agree well with theoretical predictions. The D 2 + D 2 cross sections have been measured in the velocity range between 190 m/s and 1000 m/s. No orbiting resonances have been observed, but in the oD 2 + oD 2 cross section a deep minimum between the l = 4 and the l = 5 resonances at low velocities is clearly suggested. Initial measurements of the HD + HD cross section suggests the presence of the l = 4 orbiting resonance near a relative velocity of 300 m/s. The experimental results for each system were normalized to the total cross sections, which were convoluted to account for experimental velocity and angular dispersions. Three different potentials were considered, but a chi-square fit of the data indicates that the Schaefer and Meyer potential, which has been theoretically obtained from first principles, provides the best overall description of the hydrogen systems in the low collisional energy range

    Quantification of muscle protein synthesis (MPS) remains a cornerstone for understanding the control of muscle mass. Traditional [13C]amino acid tracer methodologies necessitate sustained bed rest and intravenous cannulation(s), restricting studies to ∼12 h, and thus cannot holistically inform on diurnal MPS. This limits insight into the regulation of habitual muscle metabolism in health, aging, and disease while querying the utility of tracer techniques to predict the long-term efficacy of anabolic/anticatabolic interventions. We tested the efficacy of the D2O tracer for quantifying MPS over a period not feasible with 13C tracers and too short to quantify changes in mass. Eight men (22 ± 3.5 yr) undertook one-legged resistance exercise over an 8-day period (4 × 8–10 repetitions, 80% 1RM every 2nd day, to yield “nonexercised” vs. “exercise” leg comparisons), with vastus lateralis biopsies taken bilaterally at 0, 2, 4, and 8 days. After day 0 biopsies, participants consumed a D2O bolus (150 ml, 70 atom%); saliva was collected daily. Fractional synthetic rates (FSRs) of myofibrillar (MyoPS), sarcoplasmic (SPS), and collagen (CPS) protein fractions were measured by GC-pyrolysis-IRMS and TC/EA-IRMS. Body water initially enriched at 0.16–0.24 APE decayed at ∼0.009%/day. In the nonexercised leg, MyoPS was 1.45 ± 0.10, 1.47 ± 0.06, and 1.35 ± 0.07%/day at 0–2, 0–4, and 0–8 days, respectively (∼0.05–0.06%/h). MyoPS was greater in the exercised leg (0–2 days: 1.97 ± 0.13%/day; 0–4 days: 1.96 ± 0.15%/day, P < 0.01; 0–8 days: 1.79 ± 0.12%/day, P < 0.05). CPS was slower than MyoPS but followed a similar pattern, with the exercised leg tending to yield greater FSRs (0–2 days: 1.14 ± 0.13 vs. 1.45 ± 0.15%/day; 0–4 days: 1.13 ± 0.07%/day vs. 1.47 ± 0.18%/day; 0–8 days: 1.03 ± 0.09%/day vs. 1.40 ± 0.11%/day). SPS remained unchanged. Therefore, D2O has unrivaled utility to quantify day-to-day MPS in humans and inform on short

  5. Stopped-flow studies of carbon dioxide hydration and bicarbonate dehydration in H2O and D2O. Acid-base and metal ion catalysis

    The approach to equilibrium between carbon dioxide and bicarbonate has been followed by zero-order kinetics both from direction of CO 2 hydration and HCO 3 - dehydration. The rates are monitored at 25.0 0 C using stopped-flow indicator technique in H 2 O as well as D 2 O. The hydration of CO 2 is subject to catalysis by H 2 O (k 0 = 2.9 x 10 -2 s -1 ) and OH - (k/sub OH - / = 6.0 x 10 3 M -1 s -1 ). The value of 0.63 for the ratio k/sub OH - //k/sub OD - / is consistent with a mechanism utilizing a direct nucleophilic attack of OH - on CO 2 . In reverse direction HCO 3 - dehydration is catalyzed predominantly by H 3 O + (k/sub H 3 O + / 4.1 x 10 4 M -1 s -1 ) and to a much lesser degree by H 2 O (k 0 = 2 x 10 -4 s -1 ). The value of 0.56 for ratio k/sub H 3 O + //kD 3 O + / indicates that HCO 3 - may be protonated either in a preequilibrium step or in a rate-determining dehydration step. Both the hydration of CO 2 and the dehydration of bicarbonate are subject to general catalysis. For CO 2 , dibasic phosphate, a zinc imidazole complex, and a copper imidazole complex all enhanced the rate of hydration with respective rate coefficients of 3 x 10 -1 , 6.0, and 2.5 M -1 s -1 . For bicarbonate, monobasic phosphate catalyzed the rate of dehydration (k/sub H 2 PO 4 - / = 1 x 10 -1 M -1 s -1 ). Additionally in going from an ionic strength of 0.1 to 1.0 there was a negligible salt effect for the water-catalyzed hydration of CO 2 . However, the rate constant for the hydronium ion catalyzed dehydration of HCO 3 - was reduced from 4.1 x 10 4 M -1 s -1 to 2.3 x 10 4 M -1 s -1 for the same change in ionic strength. Finally the rate of CO 2 uptake by the complex Co(NH 3 ) 5 OH 2 3+ was followed spectrophotometrically both in H 2 O and D 2 O to determine the solvent isotope effect for a reaction known to involve a nucleophilic attack of a Co(III)-hydroxo complex on CO 2

  6. Ion temperature measurements of H-, D- and He-plasmas in the TCA tokamak by collective Thomson scattering of D2O laser radiation

    Development of collective Thomson scattering as a method to measure the ion temperature of a tokamak plasma has been successful and encouraging results have been obtained during experiments on TCA in H-, D- and He-plasmas. Using a laser source in the far-infrared spectral region allows scattering angles close to 90 o , which results in excellent spatial resolution. The system installed on the TCA tokamak comprises an optically pumped D 2 O laser emitting 0.5 J in a 1.4 μs pulse on its Raman transition at 385μm. A heterodyne receiver with a Schottky barrier diode mixer has been chosen to detect the scattered radiation and analyze its spectral distribution in 12 channels of 80 MHz. Recent improvements of the mixer and 1st IF-amplifier yielded a system NEP of 2.2·10 -19 W/Hz. As a consequence we have obtained results which allow for the first time to evaluate the ion temperature T i in a single laser shot. (author) 3 figs., 1 tab

  7. Photodissociation of water. II. Wave packet calculations for the photofragmentation of H2O and D2O in the B˜ band

    A complete three-dimensional quantum mechanical description of the photodissociation of water in the B˜ band, starting from its rotational ground state, is presented. In order to include B˜-X˜ vibronic coupling and the B˜-Ã Renner-Teller coupling, diabatic electronic states have been constructed from adiabatic electronic states and matrix elements of the electronic angular momentum operators, following the procedure developed by A. J. Dobbyn and P. J. Knowles [Mol. Phys. 91, 1107 (1997)], using the ab initio results discussed in the preceding paper. The dynamics is studied using wave packet methods, and the evolution of the time-dependent wave function is discussed in detail. Results for the H2O and D2O absorption spectra, OH(A)/OH(X) and OD(A)/OD(X) branching ratios, and rovibrational distributions of the OH and OD fragments are presented and compared with available experimental data. The present theoretical results agree at least qualitatively with the experiments. The calculations show that the absorption spectrum and the product state distributions are strongly influenced by long-lived resonances on the adiabatic B˜ state. It is also shown that molecular rotation plays an important role in the photofragmentation process, due to both the Renner-Teller B˜-X˜ mixing, and the strong effect of out-of-plane molecular rotations (K>0) on the dynamics at near linear HOH and HHO geometries.

    storage of the hydrogen atom. In such case, neutron tomography does not give information of the pore structure as neutrons will strongly scatter of H and the data have low count and low statistics or low neutron transmission. Hence, as the comparison and the possible tuning technique, neutron tomography measurements are performed on a Deuterium Oxide (D2O) or heavy water samples the same dimensions, cement composition, cement/liquid content and hydration time as the H2O samples. The advantage of using heavy water is that the total neutron cross-section for Deuterium is approximately four times smaller than Hydrogen's and, thus, permits better neutron transmission, i.e. better statistics. D2O does not alter cement properties or its chemical composition; therefore, the samples are almost identical. Comparison of the measurements using water and heavy water samples and the preparation of the measurement cement samples are discussed in this

    Apparent molar volumes for dilute solutions of NaClO 4 and [Co(en) 3 ](ClO 4 ) 3 in D 2 O and H 2 O were measured by using a dilatometry technique at 278, 298 and 318K. Comparison of limiting slopes with the Debye-Huckel predictions from the dielectric constant and compressibility of H 2 O and D 2 O is complicated by ion pairing. The apparent molar volumes for NaClO 4 were less in D 2 O than in H 2 O. The complex [Co(en) 3 ](ClO 4 ) 3 when studied in D 2 O had its amine protons exchanged by deuterium; this did not allow a direct comparison of the apparent molar volumes of the protonated complex in each solvent system, but revealed a large isotope effect. The apparent molar volumes of the [Co(en) 3 ](ClO 4 ) 3 showed a much larger temperature dependence than that of NaClO 4

    The enthalpies of solution of ordinary (H 2 O) and heavy (D 2 O) water in nitromethane (NM), acetonitrile (ACN) and propylene carbonate (PC) were measured calorimetrically at 298.15 K. Standard (at the infinite dilution) enthalpies of solution and solvation, along with D 2 O-H 2 O solute isotope effects on the quantities in question, were calculated. The enthalpies of solution of water H/D isotopologues were found to be positive by sign and substantially increasing in magnitude on going from ACN and PC to NM, whereas the corresponding positive solute H/D isotope effect changes in a consequence: NM > ACN > PC. The qualitative interrelations between the enthalpy-isotopic effect of dissolution (solvation) of water and the electron-accepting/donating ability of aprotic dipolar solvent (within a series considered) were found.

    We have studied light emission kinetics and analyzed carrier recombination channels in HgTe quantum dots that were initially grown in H2O. When the solvent is replaced by D2O, the nonradiative recombination rate changes highlight the role of the vibrational degrees of freedom in the medium surrounding the dots, including both solvent and ligands. The contributing energy loss mechanisms have been evaluated by developing quantitative models for the nonradiative recombination via (i) polaron states formed by strong coupling of ligand vibration modes to a surface trap state (nonresonant channel) and (ii) resonant energy transfer to vibration modes in the solvent. We conclude that channel (i) is more important than (ii) for HgTe dots in either solution. When some of these modes are removed from the relevant spectral range by the H2O to D2O replacement, the polaron effect becomes weaker and the nonradiative lifetime increases. Comparisons with CdTe quantum dots (QDs) served as a reference where the resonant energy loss (ii) a priori was not a factor, also confirmed by our experiments. The solvent exchange (H2O to D2O), however, is found to slightly increase the overall quantum yield of CdTe samples, probably by increasing the fraction of bright dots in the ensemble. The fundamental study reported here can serve as the foundation for the design and optimization principles of narrow bandgap quantum dots aimed at applications in long wavelength colloidal materials for infrared light emitting diodes and photodetectors.

    Full Text Available Peran teknologi informasi dalam suatu instansi sudah tidak dapat dielakkan lagi, mengingat perkembangannya yang begitu pesat seiring berjalannya waktu. Namun masalah yang sering terjadi di instansi adalah penggunaan teknologi informasi yang kadang tidak sesuai dengan harapan. Oleh karena itu diperlukan tata kelola terhadap penggunaan teknologi informasi yang biasa disebut dengan IT Governance. Fakultas teknik UNDIP adalah salah satu fakultas yang dalam operasionalnya sangat mengandalkan teknologi informasi, baik dalam aktifitas belajar mengajar maupun dalam menjalankan operasional bisnis. Kondisi sekarang di Fakultas Teknik sendiri tidak terdapat suatu indikator yang dapat menyatakan bahwa kinerja TI yang berjalan telah sesuai dengan visi dan misi Fakultas Teknik, oleh karena itu perlu dilakukan analisis tata kelola teknologi informasi, guna mengetahui performa TI sekarang sesuai dengan yang diharapkan oleh managemen atau tidak. Hasil dari analisis ini berupa tingkat kematangan tata kelola TI yang mecerminkan kondisi tata kelola TI di Fakultas Teknik dengan mengacu pada maturity level yang disediakan kerangka kerja COBIT 4.1, yakni dari level 0 (non-existent sampai 5 (optimized. Berdasarkan analisis yang dilakukan, secara garis besar kondisi kematangan tata kelola TI Fakultas Teknik berada pada level 2 yakni repeatable but intuitive. Kondisi ini mengacu pada beberapa kelemahan dalam proses-proses TI yang berjalan, diantaranya penetapan dan dokumentasi tindakan, kebijakan dan prosedur yang minim, serta tidak tersedianya service level yang disetujui bersama.

    Full Text Available Minimnya perkembangan motif Songket Palembang dan menghadapi kemunculan ‘songket’ mesin yang harga jualnya jauh lebih murah membuat beberapa pengrajin tenun songket asli menggunakan material alternatif, seperti sutera campuran, benang emas campuran, dan lain-lain untuk tetap bertahan. Semaraknya tren batik di Indonesia sejak UNICEF menetapkan batik sebagai warisan tak benda asli Indonesia, namun banyak masyarakat dalam dan luar Palembang yang tidak kenal dengan Batik Palembang. Kenyataannya, karena ketidakpahaman ini dan karena sisi ekonomis menyebabkannya sebagian masyarakat terpaksa memilih tekstil hasil industri pabrik dibanding karya asli daerah. Akhirnya, kepentingan untuk mempopulerkan motif batik Palembang yang mulai terlupakan juga menjadi kepentingan penelitian ini, selain kebutuhan akan variasi baru kreasi kain Songket Palembang. Hubungan dengan Cina dan India memberikan pengaruh dalam beberapa ragam hias dan warna pada kain Songket Palembang. Kesultanan Palembang Darussalam membeli benang emas dari Cina untuk ditenun menghiasi Songket Palembang sebagai pakaian  mewah kalangan bangsawan wanita. Berdasarkan kuantitas benang dan motif yang diterapkan di dalamnya, kain songket berbeda bagi golongan penggunanya. Diketahui, sebagai komoditi dagang dari Jawa, batik juga dikenakan oleh masyarakat Palembang. Motif-motif tertentu digemari dan menjadi ciri khas motif Palembangan hingga kini. Batik Palembang tidak dibuat di Palembang melainkan di Pesisir Jawa. Oleh karena itu, motifnya merupakan paduan ragam hias flora fauna Palembang dan corak songket selain motif India dan daerah pembuatnya. Akhirnya, salah satu solusi yang ditawarkan untuk keragaman variasi ini adalah menerapkan teknik batik di atas permukaan kain Songket Palembang sebagai salah satu cara menghias permukaan kain. Penerapan ini dapat dilakukan karena kain terbuat dari benang sutera alam. Menggunakan mode kualitatif, data-data didapat melalui literatur, wawancara dan

  11. Novel two-step laser ablation and ionization mass spectrometry (2S-LAIMS) of actor-spectator ice layers: Probing chemical composition of D2O ice beneath a H2O ice layer

    International Nuclear Information System (INIS)

    Yang, Rui; Gudipati, Murthy S.

    2014-01-01

    In this work, we report for the first time successful analysis of organic aromatic analytes imbedded in D 2 O ices by novel infrared (IR) laser ablation of a layered non-absorbing D 2 O ice (spectator) containing the analytes and an ablation-active IR-absorbing H 2 O ice layer (actor) without the analyte. With these studies we have opened up a new method for the in situ analysis of solids containing analytes when covered with an IR laser-absorbing layer that can be resonantly ablated. This soft ejection method takes advantage of the tenability of two-step infrared laser ablation and ultraviolet laser ionization mass spectrometry, previously demonstrated in this lab to study chemical reactions of polycyclic aromatic hydrocarbons (PAHs) in cryogenic ices. The IR laser pulse tuned to resonantly excite only the upper H 2 O ice layer (actor) generates a shockwave upon impact. This shockwave penetrates the lower analyte-containing D 2 O ice layer (spectator, a non-absorbing ice that cannot be ablated directly with the wavelength of the IR laser employed) and is reflected back, ejecting the contents of the D 2 O layer into the vacuum where they are intersected by a UV laser for ionization and detection by a time-of-flight mass spectrometer. Thus, energy is transmitted from the laser-absorbing actor layer into the non-absorbing spectator layer resulting its ablation. We found that isotope cross-contamination between layers was negligible. We also did not see any evidence for thermal or collisional chemistry of PAH molecules with H 2 O molecules in the shockwave. We call this “shockwave mediated surface resonance enhanced subsurface ablation” technique as “two-step laser ablation and ionization mass spectrometry of actor-spectator ice layers.” This method has its roots in the well-established MALDI (matrix assisted laser desorption and ionization) method. Our method offers more flexibility to optimize both the processes—ablation and ionization. This new technique

    Dimensional changes of the high-temperature proton conductor Ba 3 Ca 1.18 Nb 1.82 O 9-δ , when exposed to D 2 O vapor, were investigated using length-change and precision density measurements. Such information is essential for possible applications of proton conductors in solid oxide fuel cells and humidity and hydrogen sensors. A linear increase of the sample lengths with increases in the deuterium content was observed. Comparison of the present D 2 O data with those that were previously obtained for H 2 O showed that there was a small isotope effect in the lattice expansion. The fact that the length-change-versus-hydrogen-isotope-concentration curves were almost isotope independent supported the validity of the take-up reaction H 2 O(g) + V sm-bulletsm-bullet O + O x O right-reversible 2OH sm-bullet O , where V O is the vacancies in the oxygen sublattice and OH sm-bullet O is the proton that are embedded in the electron cloud of an oxygen atom. In regard to the latter equation, it was found that small islands of silver, palladium, nickel, and platinum act as catalytic promoters of the reaction and lead, for given heavy-water-steam exposure conditions, to an increase of water absorption of up to 100%, when compared with samples without the catalytic surface layers

    Elemental sulfur, as a transient intermediate compound, by-product, or catalyst, plays significant roles in thermochemical sulfate reduction (TSR) reactions. However, the mechanisms of the reactions in S-H2O-hydrocarbons systems are not clear. To improve our understanding of reaction mechanisms, we conducted a series of experiments between 200 and 340 °C for S-H2O-CH4, S-D2O-CH4, and S-CH4-1m ZnBr2 systems in fused silica capillary capsules (FSCC). After a heating period ranging from 24 to 2160 hours (hrs), the quenched samples were analyzed by Raman spectroscopy. Combined with the in situ Raman spectra collected at high temperatures and pressures in the S-H2O and S-H2O-CH4 systems, our results showed that (1) the disproportionation of sulfur in the S-H2O-CH4 system occurred at temperatures above 200 °C and produced H2S, SO42-, and possibly trace amount of HSO4-; (2) sulfate (and bisulfate), in the presence of sulfur, can be reduced by methane between 250 and 340 °C to produce CO2 and H2S, and these TSR temperatures are much closer to those of the natural system (2O-CH4 system may take place simultaneously, with TSR being favored at higher temperatures; and (4) in the system S-D2O-CH4, both TSR and the competitive disproportionation reactions occurred simultaneously at temperatures above 300 °C, but these reactions were very slow at lower temperatures. Our observation of methane reaction at 250 °C in a laboratory time scale suggests that, in a geologic time scale, methane may be destroyed by TSR reactions at temperatures > 200 °C that can be reached by deep drilling for hydrocarbon resources.

  3. Water oxidation by photosystem II: H(2)O-D(2)O exchange and the influence of pH support formation of an intermediate by removal of a proton before dioxygen creation.

    Understanding the chemistry of photosynthetic water oxidation requires deeper insight into the interrelation between electron transfer (ET) and proton relocations. In photosystem II membrane particles, the redox transitions of the water-oxidizing Mn complex were initiated by nanosecond laser flashes and monitored by absorption spectroscopy at 360 nm (A(360)). In the oxygen evolution transition (S(3) + hν → S(0) + O(2)), an exponential decrease in A(360) (τ(O(2)) = 1.6 ms) can be assigned to Mn reduction and O(2) formation. The corresponding rate-determining step is the ET from the Mn complex to a tyrosine radical (Y(Z)(ox)). We find that this A(360) decrease is preceded by a lag phase with a duration of 170 ± 40 μs (τ(lag) at pH 6.2), indicating formation of an intermediate before ET and O-O bond formation and corroborating results obtained by time-resolved X-ray spectroscopy. Whereas τ(O(2)) exhibits a minor kinetic isotope effect and negligible pH dependence, formation of the intermediate is slowed significantly both in D(2)O (τ(lag) increase of ∼140% in D(2)O) and at low pH (τ(lag) of 30 ± 20 μs at pH 7.0 vs τ(lag) of 470 ± 80 μs at pH 5.5). These findings support the fact that in the oxygen evolution transition an intermediate is created by deprotonation and removal of a proton from the Mn complex, after Y(Z)(ox) formation but before the onset of electron transfer and O-O bond formation.

    Full Text Available Wireless ad-hoc merupakan sebuah skema jaringan yang didesain supaya mampu beroperasi tanpa membutuhkan infrastruktur tetap serta bersifat otonom. Teknik flooding pada proses path discovery dalam kasus wireless ad-hoc network dapat menimbulkan masalah beban jaringan yang berlebihan. Oleh karena itu, sebuah skema clustering diusulkan untuk mengurangi adanya flooding paket yang berlebihan dengan membagi node-node dalam jaringan menjadi beberapa bagian berdasarkan parameter tertentu. Teknik ini efektifuntuk mengurangi paket yang harus dilewatkan dalam jaringan. Namun masalah muncul ketika sebuah jaringan wireless ad-hoc harus membentuk sebuah cluster dengan mempertimbangkan beberapa parameter khusus. Parameter tersebut harus disesuaikan dengan kasus yang dihadapi. Pada tulisan ini akan dibahas secara khusus mengenai penerapan skema clustering dalam lingkungan wireless ad-hoc network, baik pada MANETdan penyesuaian skema clustering yang harus dilakukan pada VANET berdasarkan mobilitasnya.

    Full Text Available Sistem OFDM cocok digunakan sebagai solusi yang dapat memenuhi layanan komunikasi data kecepatan tinggi karena memiliki efisiensi bandwidth dengan performansi terbaik. Namun dalam implementasinya, sistem OFDM memiliki kelemahan yang disebabkan oleh tingginya nilai Peak to Average Power Ratio (PAPR sehingga sinyal OFDM rentan terkena distorsi nonlinear yang disebabkan oleh adanya komponen RF power amplifier yang menyebabkan kompleksitas komponen Analog to Digital Converter (ADC yang terdapat pada Wireless Open Access Research Platform (WARP. Nilai PAPR yang besar pada OFDM membutuhkan power amplifier dengan dynamic range yang lebar untuk mengakomodasi sinyal, apabila hal tersebut tidak terpenuhi maka menyebabkan distorsi nonlinear dan pada akhirnya menurunkan performansi OFDM. Oleh karena itu, untuk mengatasinya dibutuhkan suatu metode yang dapat mereduksi nilai PAPR salah satunya menggunakan metode PTS. Guna melihat unjuk kerja teknik PTS, maka pada penelitian ini dibandingkan dua skema antara sistem OFDM tanpa dan dengan teknik PTS menggunakan analisa pada bit error rate dan nilai CCDF. Dari hasil pengukuran menunjukkan bahwa implementasi kinerja teknik PTS mampu meningkatkan kinerja sistem OFDM saat terkena distorsi nonlinear, terlihat pada pengukuran dengan modulasi 16-QAM untuk gain 56 didapatkan peningkatan BER sebesar 95.98%. Sedangkan pada grafik CCDF terjadi penurunan nilai PAPR sebesar 34.17% untuk M=4.

    Full Text Available ABSTRAK Pada gedung Jurusan Teknik Elektro Fakultas Teknik Universitas Udayana, banyak menggunakan energi listrik untuk berbagai sarana dalam memberi kenyamanan bagi mahasiswa maupun staff. Salah satu usaha dalam memberi kenyamanan tersebut adalah dengan memasang sistem pengkondisian udara. Karena banyaknya ruangan yang menggunakan sistem pengkondisian udara, maka diperlukan evaluasi pada kapasitas sistem pengkondisian udara tersebut sehingga dapat diketahui kondisi besar kapasitas AC terpasang. Pemakaian software dalam penghitungan akan sangat membantu kecepatan dalam penghitungan kapasitas sistem pengkondisian udara yang dibuat dengan menggunakan Microsoft Visual Studio. Selain itu evaluasi dilakukan pada penggunaan timer pada gedung DH karena timer pada gedung DH sudah tidak bekerja dengan baik dan waktu operasi AC belum efektif. Pada hasil perhitungan terdapat 18 ruangan dimana kapasitas AC terpasang kurang dari hasil perhitungan dan 3 ruangan kapasitas AC terpasang melebihi hasil perhitungan. Hal ini disebabkan penghitungan kapasitas AC terpasang belum menambahkan faktor penambahan kalor dari luar dan dari dalam ruangan. Evaluasi kinerja timer yang dilakukan pada gedung DH yaitu dengan mengevaluasi waktu operasi AC dimana kerja AC sebelumnya 8 jam waktu operasi selama 7 hari dikurangi menjadi 8 jam selama 5 hari karena pada hari sabtu dan minggu merupakan hari libur kuliah sehingga konsumsi energi listrik berkurang sebesar 580,34 kWh/minggu Kata kunci : Evaluasi, Air Conditioner (AC, Kapasitas AC.

    Full Text Available Radar merupakan sistem pemancar dan penerima gelombang elektromagnetik untuk mendeteksi, mengukur jarak dan membuat peta benda benda seperti pesawat terbang, kapal laut, kendaran bermotor dan informasi cuaca. Salah satu kendala yang dihadapi pada sistem radar adalah sinyal pantulan yang memiliki daya yang rendah sehingga kualitas penerimaan menjadi kurang baik. Untuk mengatasi kendala tersebut dibutuhkan penguat daya pada sistem penerima yaitu Low Noise Amplifier (LNA. Oleh karena itu, tulisan ini memaparkan perancangan LNA dengan menggunakan teknik Non Simultaneous Conjugate Match (NSCM untuk aplikasi radar S-Band. Teknik ini memberikan kemudahan dalam menentukan nilai trade off (TO untuk nilai gain, noise figure (NF dan Voltage Standing Wave Ratio (VSWR yang diinginkan. Dalam proses perancangannya, perangkat lunak Agilent Design System (ADS 2011 digunakan untuk mendapatkan hubungan antara lingkaran gain, lingkaran NF, lingkaran VSWR, dan lingkaran mismatch factor (M. Dari hubungan tersebut diperoleh nilai impedansi masukan dan keluaran dari komponen aktif. Dalam tulisan ini, LNA dirancang dua tingkat untuk mendapatkan penguatan yang tinggi. Masing-masing tingkat menggunakan komponen aktif BJT BFP420 dengan penguatan dirancang sebesar 13,50 dB untuk tingkat pertama dan kedua, dan M sebesar 0,98. Sedangkan untuk saluran penyesuai impedansinya menggunakan substrat teflon fiberglass DiClad527. Hasil simulasi menunjukkan karakteristik LNA pada frekuensi 3 GHz yaitu gain sebesar 28,80 dB, NF sebesar 2,80 dB, VSWRin sebesar 1,05 dan VSWRout sebesar 1,1.

    Full Text Available This study proposed a combination of steganography and cryptography techniques using LSB and RSA methods. RSA is a popular cryptographic technique that can be applied to digital imagery. Digital image pixel values range from 0 to 255, making the keys used in RSA limited enough and less secure. So in this study, it is proposed to convert pixel image value to 16 bits so that the key used can be more varied. Experimental results proved that there was a steady increase in security and imperceptibility. This was shown by the results of PSNR 57.2258dB and MSE 0.1232dB. This method was also resistant to salt and pepper attacks. Penelitian ini mengusulkan kombinasi teknik steganografi dan kriptografi menggunakan metode LSB – RSA. RSA merupakan teknik kriptografi yang populer dapat diterapkan pada citra digital. Nilai piksel citra digital hanya berkisar 0 sampai 255. Hal ini membuat kunci yang digunakan dalam RSA cukup terbatas sehingga kurang aman. Dalam penelitian ini diusulkan untuk mengkonversi nilai piksel citra menjadi 16 bit sehingga kunci yang digunakan dapat lebih bervariasi. Hasil eksperimen membuktikan adanya peningkatan keamanan serta nilai imperceptibility yang tetap terjaga. Hal ini dibuktikan dengan hasil PSNR 57.2258dB, MSE 0.1232dB. Metode ini juga tahan terhadap serangan salt and pepper.

    ABSTRACT   Program Studi Teknik Industri (PSTI is one of the departments in the Faculty of Engineering, University of Diponegoro. In 2015 PSTI has had a new building to support lesson activity. Along with it PSTI also get lectures supporting assets such as computers, desks, chairs and others. However, asset management in PSTI is currently not running well, PSTI has no special asset database to simplify the management and tracking of assets. PSTI asset manager at this time only use data collection using Excel to record the availability of its assets and it also had not updated. Many assets in PSTI do not have an inventory number that has been given by the Unit Layanan Pengadaan (ULP Faculty of Engineering. This condition make difficult for searching their asset. These problems often lead to asset managers in the PSTI is difficult to determine the condition of the assets is good, broken or missing. This makes the process of replacing damaged assets PSTI in ULP be no maximum. Therefore, needed an information system that can run the asset management business into a neat and structured asset management department can be easy to perform management and asset tracking. The process of designing Asset Management Information System (SIMA begins with the identification of an asset management system that is currently running in PSTI and make the proposed new system. Furthermore, of the proposed system is designed DFD (Data Flow Diagram and ERD (Entity Relationship Diagram and also the information system interface design. From the design stage and then produced a web-based information system to manage assets in PSTI. Further verification and validation to determine the suitability of the design of the system with the end result of SIMA have been made. Last is comparing the old system with a new system to determine the differences that looks after the implementation of the new system.

    Første gang publiceret i UNEV nr. 3: Internet Video: Teknik og pædagogik mødes på nettet, april - juni 2004, red. Jens Dørup. ISSN 1603-5518.

    I nærværende UNEV tema som omhandler universiteternes brug af digital video tegnes en status over dette nye medies anvendelse rundt om i landet. En række af de flittigste brugere, som også har været iblandt de første på området, fortæller om deres praktiske erfaringer, som naturligt nok har været af både teknologisk og pædagogisk art. Som universitetsundervisere og forskere er vi vandt til et relativt lavt budget, og vi har måttet klare mange teknologiske opgaver uden professionel hjælp. Til gengæld stimulerer denne situation underviseren til at inddrage pædagogiske og teknologiske aspekter samtidigt, når videomediet og det nye potentialer skal afprøves og implementeres. Som læringsmedie adskiller Internet video sig på mange måder fra TV og analoge videobånd. De indlysende forskelle – om mulighederne for uafhængighed af tid og sted – kan snart erkendes og beskrives, men erfaringerne tyder på at disse forskelle, når det gælder om at stimulere læringen, måske er mindre betydningsfulde end mulighederne for at indarbejde, forankre og samvirke netbaseret video med øvrige læringsaktiviteter. Det aktuelle tema viser at de tekniske muligheder er tilgængelige og at vi mange steder er kommet godt i gang, men også at der er langt igen før danske universiteter til fulde har lært at udnytte potentialerne i digital video.

    Full Text Available Akuakultur intensif bisa menyebabkan menurunnya kandungan oksigen dan meningkatnya kandungan limbah pada ekosistem perairan, khususnya nitrogen organik. Transfer teknologi sudah dilakukan dengan tujuan untuk mengelola kegiatan budidaya lele pada daerah terbatas menggunakan bioflok. Tujuan penelitian ini adalah membandingkan pertumbuhan ikan lele yang dipelihara menggunakan sistem bioflok dan non bioflok. Sampel penelitian yang digunakan adalah 500 bibit ikan berumur 10 hari, yang dipelihara selama 30 hari. Pengamatan dilakukan pada hari ke-0, 15, dan 30. Parameter pertumbuhan yang diamati adalah panjang dan berat ikan. Parameter lingkungan yang diamati adalah suhu air dan udara, karbondioksida terlarut, oksigen terlarut, dan pH. Hasil penelitian menunjukkan bahwa ada perbedaan peningkatan panjang dan berat tubuh benih lele pada kedua media budidaya. Meskipun peningkatan pertumbuhan tidak terlalu tinggi, namun cukup memberikan gambaran bahwa benih lele yang dipelihara dengan aplikasi bioflok mengalami pertumbuhan yang lebih baik. Hal ini mengindikasikan bahwa pakan yang diberikan dan media pemeliharaannya mampu mendukung pertumbuhan benih lele. Media pemeliharaan yang mengaplikasikan teknik bioflok menunjukkan kondisi yang lebih baik dan relatif ideal untuk pendederan lele. Hal ini juga diperkuat dengan relatif rendahnya tingkat kematian benih selama pemeliharaan, yaitu  10%. Intensive aquaculture might decrease of the dissolved oxygen and increase the wastes, particularly organic nitrogen, in the aquatic ecosystem. Technology transfer has long been made to improve the catfish rearing management in confined tanks using biofloc. The objective of the research was to compare the growth of catfish reared in non-biofloc and biofloc systems. Samples were 500 catfish seedlings aged 10 days and reared for 30 days. Observations were made on day 0, 15, and 30. Growth parameters observed were length and weight of the fish. The environmental parameters

    Full Text Available Indoor Positioning System (IPS menggunakan perangkat mobile seperti smartphone masih menjadi permasalahan yang menantang. Seperti GPS yang tidak bekerja secara akurat di dalam gedung, IPS juga memiliki kelemahan yaitu sangat bergantung pada infrastruktur gedung seperti sinyal WiFi yang terkadang tidak tersebar secara merata di seluruh bagian gedung, sehingga membuat sistem ini terkadang tidak dapat bekerja secara optimal dan real time di setiap bagian gedung. Untuk itulah dikembangkan IPS yang menggunakan sensor gerak seperti accelerometer dan magnetometer sebagai tambahan untuk melakukan update posisi secara real time dengan mendeteksi langkah dan arah hadap pengguna saat berjalan. Pertama, posisi awal pengguna harus ditentukan terlebih dahulu misalnya menggunakan sinyal WiFi yang diproses melalui klasifikasi. Setelah posisi pengguna telah ditentukan, sistem akan mendeteksi pergerakan pengguna secara real time menggunakan sensor gerak. Uji coba dilakukan menggunakan studi kasus gedung Teknik Informatika lantai tiga. Hasil yang diberikan pada saat pengujian memberikan performa yang cukup baik dengan rata-rata persentase akurasi untuk pendeteksian langkah dan estimasi arah hadap pengguna adalah sebesar 94,8% dan 94,48%.

    Full Text Available Food preservation by liquid smoke was one of the food conservation techniques that was easy to be conducted.Nonetheless, it was difficult in reality for people to product liquid smoke because of the complicated process in making pirolisis tools. This study was conducted to learn how to make liquid smoke by non pirolisis technique using the basic material of coconut fiber. And then, it must be performed in the liquid smoke, the redistilation and the adsorption process using active carbon. The quality of liquid smoke was examined by observing the components using Gas chromatography-Mass Spectrophotometry (GC-MS and performing test of antibacterial activity to three kinds of bacterias: Salmonella choleraeaeus, Bacillus subtilus, and Staphylococcus aureus using technic of well in the PCA media of 108/ml in population. Based on the study results, it was found that the original liquid smoke (without redistilation and adsorption process using active carbon consisted at least of 21 components, redistilated liquid smoke consist at least of 31 components, and adsorpted liquid smoke using active carbon consisted at least of 5 components. From the result of test of antibacterial activity, it was found that the redistilated liquid smoke showed better bacterial activity than in the original liquid smoke, whereas the absorpted liquid smoke using active carbon had the smallest activity among them. It was because of the content of the 2-methoxiphenol compound in the redistilated liquid smoke was the highest among them. And based on this phenomena, it was found that redistilation technique could increase the quality of liquid smoke of coconut fiber made by non pirolisis combusting method.

    1965-09-01

    Variations of the fast neutron spectrum in thin regions of alternating Fe and D O have been studied using threshold detectors (ln(n, n' ), S(n, p), Al(n, α)). The results have been compared to those calculated by two shielding codes (NRN and RASH D) of multigroup removal-diffusion type. The absolute fast spectrum calculated in our rather complicated configurations was found to agree with measurements within the same accuracy (a factor of two) as did the thermal flux. The calculated spectrum is slightly harder than the measured one, but the detailed variations (covering the range 1:5) in the form of the spectrum when penetrating Fe agree with observations to within 15-20 %. In and Al activities were found to be proportional to the integrated flux over 1 MeV throughout the whole configuration, while S showed the least proportionality

  16. Small-angle neutron scattering study of D2O-alcohol solutions

    1990-01-01

    Small-angle neutron scattering (SANS) measurements have been carried out on heavy water solutions of ethanol, isopropyl alcohol, n-propyl alcohol, t-butyl alcohol and butoxyethanol between 5 and 37 0 C at the concentrations where ultrasonic attenuation exhibits peak values. The wavevector dependence and the absolute intensity of the scattered intensities were analysed according to a microscopic model of the solutions in terms of aggregated complexes. The results indicate that at 25 0 C there exist either alcohol 'micelle-like' structures or alcohol-heavy water complexes which increase on going from the lower to higher alcohol solutions. As temperature increases from 25 to 37 0 C a higher aggregation is observed in butyl alcohol and butoxyethanol solutions. This behaviour is attributed to the demixing tendency of these systems at high temperatures. On going from 25 to 5 0 C the aggregation increases again. This trend is associated with the anomalous behaviour of the specific heat and ultrasonic attenuation of these systems. The occurrence of a low-temperature phase transition suggested by these anomalies is supported by our results. (author)

    There is an urgent need for real-time monitoring of the hydrogen /deuterium ratio (H/D) for heavy water production monitoring. Based upon published literature, sound speed is sensitive to the deuterium content of heavy water and can be measured using existing acoustic methods to determine the deuterium concentration in heavy water solutions. We plan to adapt existing non-invasive acoustic techniques (Swept-Frequency Acoustic Interferometry and Gaussian-pulse acoustic technique) for the purpose of quantifying H/D ratios in solution. A successful demonstration will provide an easily implemented, low cost, and non-invasive method for remote and unattended H/D ratio measurements with a resolution of less than 0.2% vol.

    1983-01-01

    The fluorescence properties of tryptophan in water and deuterated water have been examined. Tryptophan molecules exhibit three distinct fluorescence lifetimes in water which become longer in deuterated water; the two shorter lifetimes are present below the pK of the amino group and the long lifetime appears as the pH is raised through this pK. The steady-state quenching of tryptophan fluorescence by hydrogen ion in the region of pH less than 3 shows a definite wavelength effect, consistent with less-pronounced quenching of the subnanosecond component whose emission maximum is at 330 nm. The Stern-Volmer plots show a marked curvature in the direction of decreasing Stern-Volmer constant as [H 3 O + ] increases. Deuterium ion also quenches tryptophan fluorescence at low pD. A kinetic scheme is proposed which reproduces both the steady-state and lifetime quenching results. Tryptophan in methanol or ethanol exhibits three fluorescence lifetimes; the relative percentage of the long component vs. the intermediate component can be varied by the addition of triethylamine or acid. In dimethyl sulfoxide, tryptophan and tryptophan deuterated at the amino and ring nirogen positions show identical behavior, both having the same decay parameters. These results are discussed in light of the theories which have recently been proposed to account for the several components in tryptophan fluorescence decay. Solvent interaction is suggested to play a critical role

Persuasive communi-cation is an effective communication technique in education, because by using these communication techniques students are able to do something that they are desired by a teacher without feeling any burden and fear. The learning process is actually the activity of communication and social interactions between teachers and students in order to deliver the knowledge face to face either in small groups and large groups. In learning activities, there is teaching techniques so that the learning objectives are able to be achieved. The activity of persuasive communication in education is a communication that orients to students’ psychological in order to raise the awareness to learn for their future and the Indonesian’s drem. The teacher should broad themselves with the theories of persuasive communi-cation to make them effective communicator. The communication and education are not much difference. The differences are just the purpose of communication and education. From the effects’ point of view, the goal of communication is general while the goal of education is specific. The purpose of education is specific; to raise the knowledge of someone about something until that person is able to master it while the purpose of communication is to change the attitudes and opinions

    Full Text Available According to the medium, arts can be classified into the art of visual, the art of hearing, and the art of words. Those included in the art of visual are dance and fine art, in the art of hearing is music and in the art of words is poetry. This paper describes one of the art of the visual—dance, which use human body and its movement as a medium of expression. Fact shows that a dance performance exists due to the involvement of supporting elements such as visual disposition. Certain dances limit themselves to the supporting elements of costumes, make-up, property (tools and musical instruments; others equip with stages, decorations, and lightings. Traditional dances—in particular—extensively equip themselves with supporting elements to show its characteristics. Thus, since dance requires the supporting element of visuals, it is reasonable to observe it as similar to the way we observe the object of fine art. The scope of observation for the supporting elements of dance performance may cover the whole visual events or just merely one of the scenes. Therefore, a contextual knowledge of both inside and outside can be fully grasped to form the background of the dance performance.

    1 - Nature of physical problem solved: Evaluation of the energy transfer matrix and its first, second and third Legendre components for protons bound in water or polyethylene, and for deuterons bound in heavy water. Further output, the isotropic scattering matrix with diagonal elements corrected for first order anisotropy, scattering and transport cross sections, nth moment of energy transfer mn(e) (n=1,2,3), and Maxwellian averages of these moments, of the transport mean free path and of the scattering cross sections. 2 - Method of solution: For down-scattering the elements of the matrix are calculated directly from the analytical formulae (BNL 5826, p 69 FF (1961)). For scattering in the same speed (energy) group, a linear average is taken of four terms, scattering from the typical speed point of that group to four equidistant points in that same interval. Up-scattering elements are computed from detailed balance. The Bessel functions that appear are calculated following an algorithm due to Stegun and Abramowitz (see references). The anisotropic version of GAKER, which is due to Koppel and Young (see references) is also included in GAKER-KIRA, and the integration over the orientation angles is done by a 5-points Gauss quadrature. 3 - Restrictions on the complexity of the problem: A maximum number of 55 speed groups is permitted

    Films of highly oriented DNA (A-, B-, and C-conformation) were investigated by neutron scattering. Diffuse sheets corresponding to a one-dimensionally periodic ''water-DNA'' structure are identified close to the intersection of the helix direction with the structure factor maximum of bulk water. The correlation length in this structure is strongly influenced by its commensurability with the axial translation H per nucleotide. The fiber or lateral chain interaction is enhanced in the commensurate case. 10 refs., 3 figs

    The magnetic properties of CoBr 2 .6H 2 O and the anomalous effects upon deuteration have been studied. The experimental techniques employed are described and the high-temperature behaviour of the susceptibility analysed in terms of a crystal-field model combined with a high-temperature expansion for the exchange contribution. The high-temperature behaviour of the specific heat is studied and several kinds of experiments performed in the ordered state below Tsub(N). The XY plane anisotropy is deduced from antiferromagnetic resonance data and attention paid to the spatial dimensionality of the system. A comparison of parameters determined from experiments below and above Tsub(N) is made and the effects of deuteration discussed. (Auth.)

    The cold neutron technique has been applied to the study of the scattering properties of light and heavy water. It is shown that with respect to neutron scattering water behaves much like a solid. It is estimated that a water molecule occupies a stationary position for a period of 2x10 -12 seconds performing about 10 vibrations before it makes a diffusion jump of a length of at least 15 nm. The consequences of the observations for neutron thermalization problems are discussed briefly

    The January 2, 1992 explosion in an electrochemistry laboratory at SRI International (SRI) resulted in the death of scientist Andrew Riley, and gained some notoriety due to its association with experimental work in the controversial field of cold fusion research. Selected components of explosion debris were subjected to forensic analyses at LLNL to elucidate potential causes of, or contributing factors to, the explosion. Interrogation of the debris by LLNL encompassed nuclear, chemical, physical, and materials investigations. Nuclear studies for the determination of tritium and neutron-activation products in stainless steel and brass were negative. No evidence of signature species indicative of orthodox nuclear events was detected. The inorganic and particulate analyses were likewise negative with respect to residues of unexpected chemical species. Such target compounds included conventional explosives, accelerants, propellants, or any exceptional industrial chemicals. The GC-MS analyses of trace organic components in the explosion debris provided perhaps the most interesting results obtained at LLNL. Although no evidence of organic explosives, oxidizers, or other unusual compounds was detected, the presence of a hydrocarbon oil in the interior of the electrochemical cell was established. It is likely that its source was lubricating fluid from the machining of the metal cell components. If residues of organic oils are present during electrolysis experiments, the potential exists for an explosive reaction in the increasingly enriched oxygen atmosphere within the headspace of a metal cell

    Full Text Available Promotion is a must for a university to get students. With the innocence of the promotion team about the existing student profile, it will cause the team does not know which segment should be the promotion target. The consequence is that the promotion cost will be higher. In order to have a better promotion, we can use direct marketing method. In this method, a profile model of the existing students must be first created. With this profile model, promotion team can focus the promotion only to candidate student match with the model. The advantages of this method are: promotion cost can be reduced, response rate increase, and profit also increase. In order to create a model in direct marketing, we need previous promotion data. Since previous promotion data is not available, two methods in creating preliminary models are proposed. Next, the preliminary models will be tested using data mining software available in the market. Model with minimal accuracy of 75% will be chosen. If there are more than one model with minimal accuracy of 75%, then model with the highest accuracy will be chosen. Abstract in Bahasa Indonesia: Promosi merupakan suatu keharusan bagi sebuah universitas untuk mendapatkan mahasiswa. Dengan masih awamnya tim promosi terhadap profil mahasiswa yang sudah ada, maka tim promosi melakukan promosi tanpa melihat segmen pasar yang harus dituju. Konsekuensinya adalah biaya promosi menjadi lebih mahal. Untuk melakukan promosi dengan lebih baik, dapat menggunakan metode direct marketing. Pada metode ini, model profil dari mahasiswa yang sudah ada harus dibuat terlebih dulu. Dengan menggunakan model profil ini, tim promosi dapat memfokuskan promosi hanya pada calon-calon mahasiswa yang sesuai dengan model. Keuntungan dari metode promosi ini adalah biaya promosi dapat dikurangi, tingkat respon meningkat, dan keuntungan juga meningkat. Untuk membuat model pada direct marketing dibutuhkan data dari promosi sebelumnya. Karena data promosi sebelumnya tidak tersedia, dua metode diusulkan untuk membuat model awal. Selanjutnya model awal yang dibuat dites menggunakan perangkat lunak data mining yang tersedia di pasaran. Model dengan akurasi minimal 75% dipilih. Jika ada lebih dari satu model dengan akurasi minimal 75%, maka model dengan akurasi tertinggi dipilih. Kata kunci:data mining, pemasaran langsung, klasifikasi

    Energy Technology Data Exchange (ETDEWEB)

    Held, Joergen

    2011-07-15

    In this report gasification and gas cleaning techniques for biomass are treated. The main reason for gasifying biomass is to refine the fuel to make it suitable for efficient CHP production, as vehicle fuel or in industrial processes. The focus is on production of synthesis gas that can be used for production of vehicle fuel and for CHP production. Depending on application different types of gasifiers, gasification techniques and process parameters are of interest. Two gasification techniques have been identified as suitable for syngas generation, mainly due to the fact that they allow the production of a nitrogen free gas out of the gasifier; Indirect atmospheric gasification and Pressurized oxygen blown gasification For CHP production there are no restrictions on the gas composition in terms of nitrogen and here air-blown gasification is of interest as well. The main challenge when it comes to gas cleaning is related to sulphur and tars. There are different concepts and alternatives to handle sulphur and tars. Some of them is based on conventional techniques with well-proven components that are commercially available while others more advantageous solutions, still need further development. The report deals to a minor extent with the conversion of syngas to synthetic fuels. The ongoing research and development of gasification techniques is extensive, both on national and international level. Although many process concepts and components have been demonstrated, there is still no full-scale plant for the production of synthetic fuels based on biomass. Factors affecting the choice of technology are plant size, operating conditions, the possibility for process integration, access to feedstock, market aspects, incentives and economic instruments et cetera. Increased competition for biofuels will inevitably lead to higher raw material costs. This in turn means that the fuel chains with high efficiency, such as biomethane through gasification and methanation, are favored. The lower the investment cost, the lower the financial risk. This implies that techniques that are relatively cost-effective in the smaller scale, may benefit initially. As the technology develops and experience is built up the plant size will increase.

    Full Text Available The selection of photography work object was not always in the beautiful shape. The uniqueness of an object could become its own attraction and inspiration in creating the photography work. The expression of the composition and visualization in a work art became the characteristic of the artist himself. Gurat Karat was a concept of photography work art which explored the shape, texture and color of the rust of metal, especially in the rust of iron. We could explore the simple items in our surrounding which were not longer used and already broken. The iron which was rusted had its own uniqueness and attraction to observe. The change of the characteristic and the shape was v ery contrast. Before being rusted, the surface of the iron would be smooth, but after being rusted, the surface would be rough and the color would change. It was a result of rusting process of the iron itself. The phenomenon eventually stimulated the researcher to take the rust theme of the iron as an object in this photography work art creation. In arranging this photography work, the researcher used esthetic theory of Monroe Beardsley which listed three basic esthetic charac teristics as follow: unity, intensity and complexity. The visual work in 3D display created the image of space and dimension in this work. Colase technique was used in creating this work by combining 2D photography work and the object in the original item in the photography work itself, or using the construction which was suitable with the stuck object which was adjusted with the weight of that object. In a display, this work was not only enjoyed by the sense of sight but also the sense of touch since the texture in this work art could be touch. Keywords : Expressie Photography, Rust, and Collage

    Today, several biogas plants are planned. Some are large-scale or in localizations that means a long distance to croplands. The digestate indeed contain phosphorus and nitrogen but above all large quantities of water, which makes it tempting to try to refine the product. Low concentration of nutrients in the digestate means that the theoretically possible value is low which sets high demand on resource consumption of the processes to be used. In this report you can find ammonia stripping, evaporation, ultra filter + reverse osmosis and struvite precipitation, but there might be other methods. None of these methods will generate a profit, but are dependent of that the alternative, handling of not dewatered digestate, for some reason (e.g. transport distance) is to expensive. Dewatering of digestate followed by reject water treatment with aim to transform the ammonia and organic nitrogen to airborne nitrogen (disposal) has not been discussed in this report. In this project, visits have been made to three full scale plants and one pilot plant. The techniques on these plants have been ammonia stripping to ammonium sulphate, ammonia stripping to ammonia nitrate, ultra filter + reverse osmosis and struvite precipitation (pilot plant). Any appropriate plant where evaporation with developed energy recovery is used has not been found. Both plants with ammonia stripping work satisfying as well as the struvite precipitation plant. Struvite precipitation should be seen as a way to separate the phosphate from the reject water. Ultra filter + Reverse Osmosis are a functioning technique, but the concentrate was too dilute to be possible to transport any longer distance at the current facility

    Full Text Available Estimating is a challenging task when the image sequence from a camera are directly processed because there is perspective projection that causes length and area ratio of objects in the image are not preserved. In this paper, it was used image rectification technique and Kalman filter algorithm to overcome the problems encountered in order to obtain accurate vehicle velocity estimation. Rectified images as result of image rectification were processed, then Kalman filter algorithm was executed based on the processing result of the rectified images. The result of the tests showed that geometric distortion on the objects in the image sequence could be corrected well by using image rectification. Kalman filter algorithm was also good enough in estimating vehicle velocity. The error of average velocity estimation was ±3 km/hour.

    Dehydroabietinal (DA) has been identified as an important signaling molecule in systemic acquired resistance in plants. Deuterium and tritium-labeled DA were synthesized to confirm its role in signaling and to further elucidate the mechanism by which DA induces systemic acquired resistance. Pd/H2 -catalyzed exchange of benzylic hydrogen atoms of DA with (2) H-H2 O or (3) H-H2 O was conducted with >97% label incorporation for (2) H-DA and a specific activity of 12.6 mCi/mmol for (3) H-DA synthesized from 90 mCi/mmol (3) H-H2 O. The extent of deuterium labeling at each benzylic position was determined via an inverse-gated (13) C NMR experiment. C7 and C15 were 87% and 81% labeled, respectively. Isotope-induced chemical shift changes at C6 were used to approximate the amount of singly (66%) and doubly (17%) labeled (2) H-DA at C7. Results also indicated that two of the three benzylic protons in DA underwent facile exchange. Exchange at the remaining position was likely hampered by steric interactions of nearby methyl groups at the surface of the Pd catalyst. Copyright © 2013 John Wiley & Sons, Ltd.

    2003-07-01

    About 10 pressure separators run today in commercial operation in district heating networks. Undoubtedly, the pressure separator has become a new tool for more efficient operation of district heating systems. The pressure separator makes it possible to keep different parts of the pipe network at different pressure levels without the unavoidable temperature losses of heat exchangers. The objectives of this project are to find the answers of two questions. The first question is: Will the pressure separator function in district cooling systems if it is designed in the same way as for district heating? The only difference should then be the temperatures of operation. The second question is: Is there a modified design that will perform better in district cooling systems? To find the answers of the two questions, a test rig was built in Rosenlund Power Station in Goeteborg. Also computer simulations were carried out to clarify actual phenomena. The answer to the first question is: Yes/no. Measurements show that the original design of the pressure separator can be made working at temperatures of operation typical for district cooling. It will, however, be very sensitive and is not recommended for practical applications. The answer to the second question is: Yes, there is. This makes the details of the original design less interesting. The modified design is characterized by 'Differential pressure control' instead of temperature layer control'. This means a working principle that is completely independent of operational temperatures. The TVX-tank is replaced by a 'short cut' with a spring loaded checkvalve. One of the control valves creates a differential pressure that is too low to open the check valve but high enough to keep the next checkvalve in the next short cut closed. Measurements and computer simulations show that the pressure separator in the modified design works very well in district cooling applications. The temperature losses of heat exchangers are eliminated and the safety level retained. Thrilling possibilities to save electricity exist in some cases. Most cost effective is the pressure separator if the larger areas with several customers have their pressure level adjusted in one and the same pressure separator. The disadvantage of the pressure separator is mainly that it requires a far-sighted planning of the head diagram of the entire district cooling network.

    Full Text Available CDMA is interference limited multiple access system. Because all users transmit on the same frequency,internal interference generated by the system is the most significant factor in determining system capacity andcall quality. The transmit power for each user must be reduced to limit interference, however, the power shouldbe enough to maintain the required Eb/No (signal to noise ratio for a satisfactory call quality. Maximumcapacity is achieved when Eb/No of every user is at the minimum level needed for the acceptable channelperformance. As the MS moves around, the RF environment continuously changes due to fast and slow fading,external interference, shadowing , and other factors. The aim of the dynamic power control is to limittransmitted power on both the links while maintaining link quality under all conditions. Additional advantagesare longer mobile battery life and longer life span of BTS power amplifiers.In this research will be made a sumulation of power control and multi user detection to avoid the interferencebetween MS.Observations show that the increasing number of users will decrease the value of Signal to Interfrence Ratio(SIR / SIR below the target. To cope the growing number of users increases can be done by iteration / updatingpower transmit so the convergence computation can be reached and target value SIR can be achieved. Inaddition, to reduce interference can also be done by extending the number of chips.

    The use of alternative fuels for motor vehicles has been a subject of interest for a long time and alternative fuels have also been subject to extensive investigations. Studies and investigations of the alternatives have resulted in many positive and useful results in that both advantages and disadvantages of different fuels have been evaluated. An important prerequisite for an introduction of new fuels for motor vehicles is that engines and vehicles have been developed and adapted to the new fuel. In most of the cases there are specific differences in composition and physical function between alternative fuels and the commercial fuels, petrol and diesel oil. There is therefore a need for both engines and the exhaust control systems to be developed in order to take the full advantages of the positive property of the new fuel. The aim of the project was to study the technical development of natural gas and biogas fuelled engines and vehicles which had taken place during the last few years, from both a national and an international perspective. The method used has been to visit, among others, various car manufacturers in order to ascertain the state of the art concerning the development of gaseous-fuelled vehicles. In addition an extensive literature study has been carried out aiming at a widening of the knowledge about the development of natural gas fuelled vehicles in especially in USA, Europe and Japan. The results are presented in this report, which hopefully gives a broad picture of the state of the art of current gaseous-fuelled vehicles and information concerning the technology used for the development.

    Full Text Available The aim of this research was to study the effect of spot variations on shear strength of spot welds in an electric loop space maintainer. Stainless steel wire of 0.8 mm diameter and nickel chromium crwon for lower second molar of temporary teeth were used. A loop 1 cm wide, made of 3.5 cm stainless steel wire, was welded with 3 dots on the crown using an electric spot welder. Each dot for each group took different spot variations from 1 X – 4 X. A loop space maintainer made with the usual materials and techniques as applied at the IKGA FKG UI Clinic was used as a control, with a torch as heat source. Ten specimens each were prepared for shear testing and three spesimens each for metallography. Universal testing machine was used for shear strength testing at a crosshead speed of 0.5 mm/min, and SEM/EDS was used for metallography and fractography. The data were statistically analyzed with one-way ANOVA at p = 0.05, and Tukey post hoc test. The results show that the shear strength of the welded loop space maintainer was higher than that of a soldered loop space maintainer, although the difference was not statistically significant with spot variation 1 X. SEM/EDS analysis suggests that a new alloy forms at the contact area of welded and soldered loop space maintainer. Fractography of the joints suggests that welds are better than soldered joints, with higher ductility and toughness, as can be seen from the dimpled pattern of the welded joint and cleavage patterns in the control joints. In conclusion, the loop space maintainer is better made by welding than by soldering.

    Biogas production is growing and there is an increasing demand for upgraded biogas, to be used as vehicle fuel or injected to the natural gas grid. To enable the efficient use of biogas in these applications the gas must be upgraded, i.e. the carbon dioxide, which constitutes a large part of the raw biogas from the digester, must be separated from the methane. This report aims to evaluate the biogas upgrading technologies that are commercially available and in operation today: amine scrubbers, water scrubbers, PSA units, organic scrubbers and membrane units. The technologies are described in detail by presenting the theory behind the separation mechanism, the upgrading process as a complete system, operational issues and how these are solved, and finally the most important financial data. Furthermore, the best developed cryogenic technologies, which today are being used to purify landfill gas and biogas from some specific components and to liquefy biogas, are presented. Cryogenic upgrading is an interesting possibility, but as this report shows, the technology still has some important operational issues to resolve. Technologies which are especially focused on small-scale applications are finally presented, however not in as much detail as the other, more common technologies. The report shows that for mid-scale applications, the most common options are all viable. The scrubbing technologies all perform well and have similar costs of investment and operation. The simplicity and reliability of the water scrubber has made this the preferred choice in many applications, but the high purity and very low methane slip from amine scrubbers are important characteristics. Regarding PSA and membrane units, the investment cost for these are about the same as for scrubbers. Furthermore, recent developments of the membrane units have also made it possible to reach low methane slips with this technology. Biogas production is increasing, in Sweden and globally, and the interest for biogas upgrading to utilize the gas as vehicle fuel or in other traditional natural gas applications increases as well. The mature technologies will see a market with more and harder competition as new upgrading technologies such as cryogenic upgrading are established, and other technologies optimize the processes to decrease operation costs. Important issues for the future development of the biogas market relate to the implementation of new policy instruments. The work with the new European standard requirements for gas distributed through the existing gas grids is one issue that possibly can have a large effect on possibilities for distribution of upgraded biogas. However, the future will most probably be fuelled by an increasing amount of upgraded biogas.

    Full Text Available Rainfall zoning analysis with fuzzy clustering method has been performed at the centre of paddy area in the northern coast of Banten Province and West Java Province. Rainfall data recorded in the 1980-2006 period from 62 rainfall stations in the northern coast of Banten Province and from 75 rainfall stations at Karawang and Subang in the northern coast of West Java Province have been used in this analysis. For the first analysis a calculation of arithmetic mean values representing EI-Nino, La-Nina and Normal condition has been performed. Next, a fuzzy clustering analysis is applied to these mean values. The clustering analysis consists of two steps. First, a symmetric and reflective compatibility relation matrix describing a distance function between rainfall stations is calculated. Second, a fuzzy equivalency relationship i.e. a transitive approach of fuzzy compatibility matrices is determined. The results of analysis indicate a difference in the equivalency level among the stations under the EI-Nino, La-Nina and Normal conditions in the northern coast of Banten Province and West Java Province. Based on the 75°/o equivalency level, in the northern coast of Banten area can be grouped into four rainfall zones under EI-Nino condition, two zones under La-Nina condition and three zones under Normal condition. On the other hand, in the northern coast of West Java area can be grouped into three zones under EI-Nino condition, two zones under La-Nina condition, and four zones under Normal condition.

One of important factor which determine the successful of phytoplasma amplification is the DNA availability from fresh tissues. The research was aimed to evaluate some preservation methods of phytoplasma from infected plant samples. The aspects to be evaluated consisted of time (1, 2, 3, and 4 weeks, temperature (-20 °C, 4 °C, and 25 °C, and preservation medium (1X PGB buffer, 3 M NaCl, CTAB buffer, 70% ethanol, non medium, and FTA-card for storing the fresh phytoplasma infected samples. Good preservation method will optimize the phytoplasma DNA amplification using PCR standard technique followed by nested-PCR. The results showed that preservation of samples at -20 °C, 4 °C, and 25 °C in CTAB buffer was able to maintain the tissue freshness for 4 weeks and was able to provide the DNA of either quality or quantity sufficiently for PCR detection. PCR standard using a primer pair P1/P7 showed that not all of the preserved DNA of phytoplasma were amplified positively. However, standard PCR followed by nested-PCR using primer pair fU5/rU3 was able to increase the DNA detectability. Preserved samples derived from various medium and stored for 4 weeks gave positive results.  This results were in contrary with previous same samples which were detected negatively by standard PCR technique.

    Lime stone is widely used in chemical recovery for regeneration of white liquor in kraft pulping. Slaked (hydrated) lime is used to convert (causticize) sodium carbonate into sodium hydroxide, whereby lime mud (calcium carbonate) precipitates from the solution. Lime mud is dried and reburned in a lime kiln, where burned lime (calcium oxide) is formed. The circle is closed when lime is slaked (hydrated) in green liquor in an exotherm reaction. Problems with traditional lime burning and slaking methods are that heat recovery is bad and heat is recovered at low temperatures. With the method described in this report there is potential to increase heat recovery in the causticizing plant, and to recover heat at higher temperatures. The forecasted method means that lime is slaked with water vapour, for example combined with an indirect heated lime mud drier and a lime kiln. This project is a follow-up to pilot tests performed in a specific machine equipment at year 2006. The target group is pulp and paper industry using the kraft process. The owner of this new project is Carnot AB and the project is performed inside the Vaermeforsk Program for Pulp and Paper Industry 2006-2008. Partners and advisers in project group have been KTH Energy Processes, CTH Energy and Environment, LTH Chemical Technology, SMA Mineral AB, and reference group from STORA Enso Skoghall, Sodra Cell, M-Real Husum and SCA Packaging Piteaa. The task in this stage has included market investigations and laboratory tests. Contacts have been made with suppliers, preliminary dimensioning of process equipment and budget offers are received. Economic calculations have been made out of the offers. The laboratory tests are done as an examination paper at KTH Energiprocesser on the reactivity of burned lime from kraft lime kiln when it is slaked with water vapour instead of green liquor. The vapour intended to be used is at atmospheric pressure or even down to 0,2 atm. Complementary addition to these laboratory tests are performed at Carnot AB. The evaluation indicate that a combination of lime slaking with water vapour from indirect heated lime mud dryer could be technically possible in the evaluated/studied equipments. The laboratory tests show however that the reaction speed is considerably lower than expected, leading to need for larger and somewhat more expensive equipment. Tests in the suppliers pilot test plants are necessary to guarantee the process and to determine the capacity. Such tests are offered. (author)

    This report consists of a number of independent contribution that treat different aspects of the nuclear waste complex, with the time perspective as a common starting point. The review does not pretend to cover the entire area, but the selected issues addressed are those of large general interest. First a general overview is given of how the nuclear waste issue has been treated in Sweden since the plans to use nuclear power begun be planned in the middle of the 1940s. The complex of problem around the nuclear waste issue is linked to our natural aversion against the development of nuclear weapons during they last 60-70 years, but also to the controversies around the peaceful use of the nuclear power that has happened during the latest 30-40 years. In chapters 3 the time perspective is considerably shorter, approximately 20 years. Here, construction and operation of an underground repository for nuclear waste is discussed. Such an undertaking has many resemblances with establishing an underground mine and there is much experience to learn from. In chapters 4 questions about the technical barriers are treated, the copper container, bentonite buffer and the backfilling. The copper container and bentonite buffer both have key roles to prevent ground water to come in contact with the spent fuel and that radioactivity is transported out into the environment. They must both fulfil their functions during the period when the fuel is dangerous, i.e. over 100,000 years. Different processes affects the repository, some during short periods, some during several 10,000 years. Specific intervals (from 10 years and up to 100,000 years) are indicated for the different processes, almost all with the starting point at the deposition of the waste. The possibility to gain experiences from natural analogies is treated in chapters 5. They can be seen as a prolonged experiment in natural systems where one reactor zone has been active for more than 100,000 years. The time perspective stretches itself millions of years backward in the time. In chapters 6, Geologic development, time periods on millions years backward are considered. Crystals that formed more than 1,700 million years ago can be studied today. The future climate development is an increasingly central question in the debate. The climate is governed of an ensemble of interacting astronomical factors that vary on time scales from 10,000- 100,000 years, and changes in the atmosphere's carbon dioxide concentration happen on time scales from 100 to a few thousand years, and may be caused of the man and/or nature.

    Full Text Available Laser-Induced Breakdown Spectroscopy (LIBS is a technique that used for quantitative elemental analysis of various samples in different forms. In this technique, a laser light is focused on the surface of sample yielding a plasma just above the sample surface that used for analytical source. Nowadays, rapid powder analysis in tiny amount (mg has been carried out using plasma induced by high power laser of  Nd:YAG (Neodymium-doped Yttrium Aluminium Garnet at atmospheric pressure. However, powder analysis using high power laser is still difficult to be carried out  due to blow of powder when irradiated laser beam focused on a powder sample. In general, the powder must be transformed into pellet form prior to analysis. Pellet sample requires a lot of powder and it takes time for preparation. In this study, we developed a technique of powder sample with its size about  30 µm (± 5 mg that mixed with silicon grease (± 5 mg that act as a binder. The mixed sample then thinly painted on the metal plate as sub-target. The study showed that by employing sillicon grease technique, a semiquantitative analysis of several elements contain in coal, rock, and  water  can be conducted. Meanwhile heavy metal in soils is still not able to detect. This results showed that sillicon grease technique using  Nd:YAG laser can be applied for rapid semi-quantitative analysis of powder samples available only in tiny amounts.

    Systems, techniques and economy have been analysed for biogas plants with more than 300 GWh annual energy productions. There is so far no such concept in Sweden but in Germany, a so called biogas park with 450 GWh annual biogas production will be set in operation by autumn 2007. Substratum for 300 GWh gas production are crops which corresponds to a acreage need of 6,000-11,000 hectares for silage crops such as maize or grass. If the gas production is based on corn, the acreage need is about 14 000 hectares. That means that biogas production from silage gives a higher energy outcome per hectare in comparison to grain. According to calculations, grain affects the gas price more than silage. However, grain is easy available at the world market which can be related to digestion of silage that means long term contracts with farmers nearby the biogas plant in addition to a complex logistic system for supply. The grain price by end of 2006 affects the gas price with about 0,38 kr/kWh. Large scale harvesting and transportation of silage in addition to a system for different crops to be harvested and transported directly to the digestion chamber admit reduced handling cost. Silage is expected to affect the gas price with about 0,28 kr/kWh. The price development of grain and silage can be expected to follow each other. The grain prices for 2008 seems to be higher than the notations for 2006/2007. Developed technique for digestion of grain admits 6 kg DMo/m{sup 3} chamber volume, 24 hours. That means reduced size of the digestion chamber in comparison to conventional digestion technique. In Germany where silage is the main substratum, two stage digestion with a first laying chamber admits 4 kg DMo/m{sup 3} chamber volume, 24 hours and DM-content of 12 %. The specific digestion cost for crops is about 0,13 kr/kWh. Huge amounts of digestion residue have to be handled. Dewatering makes sense since the digestion process needs additional water. The phosphorous solid fraction can be transported to farmers and spread out before sowing. Further treatment with production of pellets is an alternative for the solid fraction. The liquid fraction has a high ammonium nitrogen content and is suitable to spread out to a growing crop. In Germany, there are separation techniques available where pure water and a N-solution are extracted from the liquid fraction. The incomes from the digestion residue are expected to correspond to its handling costs in the lung run. Biogas upgrading has considerable economics of scale and has been estimated to 0,05-0,06 kr/kWh. Developed industrial processes for large scale biogas upgrading are expected to reduce the upgrading costs further. The total gas price at a vehicle gas station is estimated to 0,74 kr/kWh excl. VAT from large scale biogas production based on corn and 0,64 kr/kWh excl. VAT based on silage. The vehicle gas price today is about 0,74 kr/kWh which may make digestion of crops interesting. This report has shown that biogas can be produced in a sizeable scale and that the economics of scale make biogas production interesting, especially in comparison with ethanol production.

    Full Text Available Bit-Plane Complexity Segmentation (BPCS is a fairly new steganography technique. The most important process in BPCS is the calculation of complexity value of a bit-plane. The bit-plane complexity is calculated by looking at the amount of bit changes contained in a bit-plane. If a bit-plane has a high complexity, the bi-plane is categorized as a noise bit-plane that does not contain valuable information on the image. Classification of the bit-plane using the set cripst set (noise/not is not fair, where a little difference of the value will significantly change the status of the bit-plane. The purpose of this study is to apply the principles of fuzzy sets to classify the bit-plane into three sets that are informative, partly informative, and the noise region. Classification of the bit-plane into a fuzzy set is expected to classify the bit-plane in a more objective approach and ultimately message capacity of the images can be improved by using the Mamdani fuzzy inference to take decisions which bit-plane will be replaced with a message based on the classification of bit-plane and the size of the message that will be inserted. This research is able to increase the capability of BPCS steganography techniques to insert a message in bit-pane with more precise so that the container image quality would be better. It can be seen that the PSNR value of original image and stego-image is only slightly different.

    Full Text Available Witches’ broom disease caused by phytoplasma is a very serious disease on peanut (Arachis hypogaea which may potentially lead to high yield loss. Insects are the most important agents of phytoplasma transmission in the field. The objective of this research was to examine the potential role of leafhoppers species as insect vector of phytoplasma and to determine their transmission characteristic. Two species of leafhopper i.e. O. argentatus and Empoasca sp. (both belong to Hemiptera: Cicadellidae were chosen for this study. The methodology involved were transmission study of phytoplasma by O. argentatus and Empoasca sp., and molecular detection of phytoplasma by PCR technique to confirm the association of pathogen, insect vector and symptomatic plants. The result showed that specific symptom was observed when using O. argentatus in the transmission study with number of insect as low as 1 insect per plant, whereas Empoasca sp. was not able to transmit the disease. Incubation period of phytoplasma in the host plant was affected by the number of insect, i.e. the more insect vector the shortest incubation period. The phytoplasma was successfully detected using P1/P7 primer in symptomatic plants as well as in the insect vector.Key words: Empoasca sp., leafhoppers, polymerase chain reaction

    New laws and restrictions, in Sweden and within the EU, will change the handling of waste within the next years. The combustible wastes going to landfill today, have to be dealt with in another way in the future. The knowledge about fuel preparation has been accentuated. Preparation of wastes - properly executed - will make it a useful fuel and increase energy recovery. S.E.P. Scandinavian Energy Project AB has by the assignment of the Thermal Engineering Research Institute made this survey of required conditions technology and quality costs related to fuel preparation of recovered waste like wood, paper and plastic. Only a few fuel preparation plants for recovered waste exist in Sweden today. Most of the municipalities do not have any waste treatment except for landfill. In the future regional preparation plants will most likely be built. In that way recovered wastes can be treated in a cost-effective way and be converted into useful fuel. Transportation will increase when landfills, presently in use, will close and the waste has to be transported to regional plants. Recovered fuel can be divided into two types depending on their content. Recovered Wood Fuel is what we call RWF in this report. Recovered Commercial waste Fuel containing plastic, paper, textiles etc, is called RCF in this report. To receive a suitable fuel for a special combustion plant, the nature, quality and content of the fuel must be known. The choice of preparation equipment is guided both by the type of waste and the quality of fuel needed for the combustion plant. Different contaminations in waste are presented in the report, together with technology to separate them from the fuel. The report also focuses on some type of equipment that are available for fuel preparation in different applications. In general the waste has to be shredded or crushed and the tramp iron has to be removed. If required the waste also has to be screened. The non waste incineration plants firing RWF today and intend to continue, must probably be rebuilt to meet the future requirements, or be replaced. There will also be a demand on new waste incineration plants burning both MSW and RWF/RCF due to an increasing flow of combustible waste. Recovered fuels will compete with household wastes and wood fuel about the combustion capacity available in Sweden. The handling of recovered fuels, i.e. collecting, treatment, transport and storing is more costly than for regular wood fuel. On the other hand recovered fuels can utilise the negative cost the responsibility of waste deposition creates. This could result in competitive recovered fuels burned in plants made for prepared fuels. In traditional waste incineration plants for MSW, the recovered fuels will with difficulty be competitive more than as a dilution fuel.

    Full Text Available Oil from by-product of lemuru canning processing was a source of w-3 fatty acid but its characteristics had out been known. The content of w-3 fatty acids of this oil had to be increased. Various methods are available to enhance w-3 fatty acids concentration Rapid solidification was one of limited methods to enrich fish oil by w-3 fatty acids containing triglycerides.This research was conducted to optimize rapid solidification condition to enrich fish oil from by product of lemuru canning processing with w-3 fatty acids and characterize the enriched oil compared by International Association of Fish Meal and Oil Manufacturers standard. In optimization process, the content of EPA+OHA and yield .was maximized. A two-factors central composite design in Response Surface Method was used to study the effect of solvent-to-oil ratio (X1 and extraction time (X2. The response (Y is the multiplication of EPA+DHA content by yield.The results showed that under optimum conditions the maximum response were obtained at a solvent-to-oil ratio of 3,95:1(vw and extraction time of 24,93 hours. The w-3 fatty acids enriched fish oil had EPA+DHA content of 33,33% and yield of 9.40% (w/w.The produced w-3 fatty acids enriched fish oil had good quality based on food grade fish oil standard, unless Fe and Cu content. Chelation could reduce these oxidizing metals.

    The following techniques for small-scale production have been selected to be studied more carefully, Fuel cells, Photovoltaics, Organic Rankine Cycle (ORC), and Wave power. Of the four selected technologies, fuel cells, solar cells, ORC are appropriate for use in so-called distributed generation, to be used close to a consumer, and possibly also for the production of electricity. Wave power is more like the wind in nature and is probably better suited to be used by power companies for direct input to the transmission grid. None of these technologies are now competitive against buying electricity from the Swedish grid. However, there are opportunities for all to reduce production costs so that they can become competitive alternatives in the future, depending largely on the general development of electricity prices, taxes, delivery reliability, etc. The four different technologies have different development stages and requirements that affect their possibility for a commercial breakthrough. These technologies will probably not all get a breakthrough in Sweden. Small-scale technologies will in the time period up to 2030 not be able to compete with the large-scale technologies that exist in today's power grid. In the longer term the situation may be different. The power system might be reduced in importance if the small scale technologies become cheap, reliable and easy to use. Electricity can then be produced locally, directly related to user needs

    Full Text Available In this article it is shown how different discursive meanings of the relationship between techanology and the individual, with different possible consequences for political action, is expressed in social studies schoolbooks and curricula for the Swedish comprehensive school. The author refers to the investigation in which it is shown that the relative strength of the different discursive meanings har varied, historically, but at the same time that it is not possible to claim that any curriculem, for example the one now in use, is dominated by any specific discursive meaning. Thereby the power related and active action present in every teaching situation is focused, in which the possibility is open for different perspectives. The political aspect of this argument is made clear by focusing the critical conversations concerning technology that can be arranged in teaching situations, which in themselves can be regarded as parts of the constitution of a critical public.

    The pilot study was initiated by the need of a new technology that has been raised from the problem, and by the specifications of requirements, that has been described from the project 'Salix Maelardalen'. The need has been crystallized by the energy company Maelarenergi AB, Vaesteraas, in their handling of bio fuel, among many other fuels. The company Maelarenergi AB can see a potential in the use of Salix of a considerable volume. There is a special need by the means of the big volume handling of Salix, since the Salix raw material must be able to be delivered under a longer period or for intermediate storage. 8-9 months could be an adequate storage period. The possibility for intermediate storage could do the flow of fuel raw material to the combined power and heating plant is harmonized to the special requirements of fuel. The storage capability in chipped raw Salix chips is very short and that's why chipped Salix are not going to be a sustainable system combined with the handle of big volume together with portioned inflow to the plant. The production of Salix chips in a system of direct chipping is a very delicate system. The ground conditions with frozen and dry grounds are important for a system with heavy machines. The last years have not given such climate conditions. A big problem with practicability has been coming up. The number of days for contract work during the harvest period without interruption, because of hard conditions, has been decreased to the level that the capacity very considerably falls below what is economical defensible. The needs of larger areas for harvesting during fewer days under good conditions counteract each other. In the 'hot flow' during the harvest when the harvest machine will work with escort vehicles/container transports in the field can be impossible to realize because of for example the breakdown of the soil structure. The organization around 'hot flow system' is a very heavy programme and demand good and secure weather conditions. Heavy rain or snow is a big problem during harvest season. The proposal from Maelarenergi AB has been carefully analysed and they think this is a solution with high potential. It should mean lower costs than in compare to using a mobile fossil driven cutter. Chipped Salix on farmland is a 'hot' flowchart, with big demand on among other things the logistic in and around the system. The possibility to direct consumption with chipped Salix has a limited storage capability. Chipped Salix is not possible to transport long distance, maximum 30 - 35 km, if it should keep the capacity to pay the procedure. The costs of transport will be too big in comparison to production value. Another advantage is the costs for intermediate storage. For example the area of the intermediate storage station, can be reduced when smaller volumes with higher density are handled. An overall analysis over the project 'Salix Maelardalen' point out very obviously that an alternative to the today direct chipping system is necessary and that development work around harvest with compressing bundle technique is very important. Big positive effects on environment can also be shown. Questions around 'compressed whole straw harvest of Willow' can be answered by a pilot study. There are o lot of aspects to pay attention to and 'smooth the road' to the growing production of Salix and it's rising as fuel raw material. The pilot study is going to penetrate the development of new harvest technique and earlier systems for 'compressed whole shoot harvest' of Salix. Needs and potential of new technique will be analysed and the study will also give suggestions to a new specification of requirements.
