Abstract: Observation techniques of high-energy gamma rays using air showers have remarkably progressed via the Tibet AS$\gamma$, HAWC, and LHAASO experiments. These observations have significantly contributed to gamma-ray astronomy in the northern sky's sub-Peta electron volts (PeV) region. Moreover, in the southern sky, the ALPACA experiment is underway at 4,740\,m altitude on the Chacaltaya plateau in Bolivia. This experiment estimates the gamma-ray flux from the difference between the number of on-source and off-source events by real data, utilizing the gamma-ray detection efficiency calculated through Monte Carlo simulations, which in turn depends on the hadronic interaction models. Even though the number of cosmic-ray background events can be experimentally estimated, this model dependence affects the estimation of gamma-ray detection efficiency. However, previous reports have assumed that the model dependence is negligible and have not included it in the error of gamma-ray flux estimation. Using ALPAQUITA, the prototype experiment of ALPACA, we quantitatively evaluated the model dependence on hadronic interaction models for the first time. We evaluate the model dependence on hadronic interactions as less than 3.6\,\% in the typical gamma-ray flux estimation performed by ALPAQUITA; this is negligible compared with other uncertainties such as energy scale uncertainty in the energy range from 6 to 300 TeV, which is dominated by the Monte Carlo statistics. This upper limit of 3.6\,\% model dependence is expected to apply to ALPACA.

Abstract: This study investigated whether dual tasks comprising cognitive tasks and occupations related to daily living can improve the mental and cognitive function of Japanese community-dwelling older adults. Participants included 30 older adults, equally divided into intervention and control groups. The outcome measures were memory, attention, depression, and health-related quality of life. No adverse effects of the intervention were observed in any participant in the intervention group. Logical memory I, logical memory II, and Center for Epidemiologic Studies Depression Scale scores showed a significant interaction. Dual tasks combining cognitive tasks and occupations may help improve delayed recall and alleviate depression. A novel attempt to integrate cognitive stimulation and activities valued by individuals may help mediate age-related cognitive function decline and reduce depressive symptoms in community-dwelling older adults.

Abstract: The ALPACA experiment is a new air shower experiment mainly aiming to explore the southern sky in the VHE gamma-ray regime beyond 100 TeV. As the prototype experiment, ALPAQUITA will start in late 2021. It consists of a surface air shower array (18,450 ${\rm m}^2$) and an underground muon detector array (900 ${\rm m}^2$). In this study, the performance of ALPAQUITA including the sensitivity to gamma-ray point sources is investigated using a Monte Carlo simulation to quantitatively evaluate the possibility of detection of gamma-ray sources in the prototype phase. Corsika 7.6400 and Geant4 v10.04.p02 are used to simulate air shower development in the atmosphere and detector response, respectively. The output data are then processed and analyzed in the same way as the experiment. As a result, the study finds that the air shower array has an energy resolution of $\pm21\%$ and the angular resolution of $\simeq 0.2^{\circ}$ for gamma rays with an energy of 100 TeV. The detection area of the air shower array for gamma rays reaches $\simeq 12, 600 \, {\rm m}^2$ above $\simeq 10\, {\rm TeV}$. The muon detector rejects $\simeq 99.9\%$ of background cosmic rays and maintains $\simeq 80\%$ of signal gamma rays. This high discrimination power will enable the detection of five southern known gamma-ray sources beyond 30 TeV and the extension of the energy spectrum of one out of the five, HESS J1702-420A, up to $\simeq 300\, {\rm TeV}$ during one calendar year observation. This study concludes that ALPAQUITA will provide data enough to discuss a hot topic of VHE gamma-ray astronomy before passing the baton to ALPACA.

Abstract: HESS J1843–033 is a very high energy gamma-ray source whose origin remains unidentified. This work presents, for the first time, the energy spectrum of gamma rays beyond 100 TeV from the HESS J1843–033 region using the data recorded by the Tibet air shower array and its underground muon detector array. A gamma-ray source with an extension of 0.°34 ± 0.°12 is successfully detected above 25 TeV at (α, δ) = (281.°09 ± 0.°10, −3.°76 ± 0.°09) near HESS J1843–033 with a statistical significance of 6.2σ, and the source is named TASG J1844–038. The position of TASG J1844–038 is consistent with those of HESS J1843–033, eHWC J1842–035, and LHAASO J1843–0338. The measured gamma-ray energy spectrum in 25 TeV < E < 130 TeV is described with dN / dE = ( 9.70 ± 1.89 ) × 10 − 16 (E/40 TeV)−3.26±0.30 TeV−1 cm−2 s−1, and the spectral fit to the combined spectra of HESS J1843–033, LHAASO J1843–0338, and TASG J1844–038 implies the existence of a cutoff at 49.5 ± 9.0 TeV. Associations of TASG J1844–038 with SNR G28.6–0.1 and PSR J1844–0346 are also discussed in detail for the first time.

Abstract: Phyto-Fenton process utilizes the endogenous hydrogen peroxide in plants to degrade organic pollutants in presence of iron catalyst. In this study, we have applied the magnetite particles in continuous treatment system of constructed wetland (CW) to study the effectiveness in removing sulfamethoxazole (SMX) antibiotics. Experimental results demonstrated that SMX was removed by constructed wetlands in the presence and absence of magnetite fine particles. OH radical formation was observed in the plant+Fe system with electron spin resonance spectroscopy. The magnetite addition favoured the plant growth and endogenous H2O2. However, enhanced treatments by phyto-Fenton process were not enhanced in the presence of magnetite particles, but the plants+soil CWs showed better removal efficiencies compared to the soil CWs.

16. Mechanical loss of a multilayer tantala/silica coating on a sapphire disk at cryogenic temperatures: Toward the KAGRA gravitational wave detector

Abstract: We report the results of a new experimental setup to measure the mechanical loss of coating layers on a thin sapphire disk at cryogenic temperatures. Some of the authors previously reported that there was no temperature dependence of the mechanical loss from a multilayer tantala/silica coating on a sapphire disk, both before and after heat treatment, although some reports indicate that Ta2O5 and SiO2 layers annealed at 600 °C have loss peaks near 20 K. Since KAGRA—the Japanese gravitational-wave detector, currently under construction—will be operated at 20 K and have coated sapphire mirrors, it is very important to clarify the mechanical loss behavior of tantala/silica coatings around this temperature. We carefully investigate a tantala/silica-coated sapphire disk with the new setup, anneal the disk, and then investigate the annealed disk. We find that there is no distinct loss peak both before and after annealing under particular conditions. The mechanical loss for the unannealed disk at 20 K is about 5×10−4, as previously reported, while that for the annealed disk is approximately 6.4×10−4.

Subjects: Screw thread, Materials science, Ultimate tensile strength, Sapphire, Liquid nitrogen, Composite material, Cryogenic temperature, Instrumentation, Structural element, Tensile testing
Abstract: We fabricated several sapphire screw threads and performed a strength test on them at the liquid nitrogen temperature of 77 K. The screw threads were subjected to and withstood a 3000 N load. To the best of our knowledge, this is the first strength test of sapphire screw threads at a cryogenic temperature. The result suggests a new way of connecting sapphire components. Although sapphire is already used in many applications, the result may provide a new way to use the material as a structural element in even more applications.

Abstract: Fully-depleted 20-nm SOI complementary metal-oxide-semiconductor field effect transistors (CMOSFETs) were successfully fabricated without a raised source/drain (S/D) structure, instead using low-temperature selective tungsten CVD (SWCVD) technology that can reduce the S/D series resistance. The thickness of the residual SOI layer under the W-clad layer in the S/D region was 6 nm for an nMOSFET and 9 nm for a pMOSFET. For 0.15-/spl mu/m-gate CMOSFETs, the subthreshold swings were 70 and 75 mV/dec for the nMOSFET and pMOSFET, respectively. The effectiveness of SWCVD technology when applied to ultrathin SOI devices was confirmed by small Si consumption and good continuity between the W and SOI layers. We expect that the S/D series resistance can be reduced to less than 1 k/spl Omega/-/spl mu/m by optimizing the S/D implantation conditions.

Abstract: A numerical model for lean NOx catalytic reaction in consideration of hydrocarbon adsorption and desorption process, which is capable of predicting the performance of diesel lean NOx catalyst using diesel fuel as a supplemental reductant, has been developed. This model is based on our simplified kinetics for the adsorption and desorption of hydrocarbons, for the oxidation of hydrocarbons, and for the reduction of NOx by hydrocarbons including the desorbed one. The adsorption of diesel exhaust hydrocarbons was expressed by the Freundlich-type isotherm that has the adsorption equilibrium constant of exponential temperature dependence. The behavior of HC and NOx reactions and HC adsorption and desorption in diesel exhaust has been simulated successfully.

Abstract: A rapid-scanning spectrometer was developed for versatile use in atomic emission spectroscopy. The sine bar was removed and a laser rotary encoder was fitted to the grating shaft for wavelength synchronization. The pulses produced by the encoder when the grating shaft was driven back and forth in sector movements were counted to detect the grating angle and the wavelength. The wavelength accuracy and precision obtained were ±0.26 and ±0.013 nm, respectively. The maximum scanning speed was limited below 4000 nm/s by a malfunction in wavelength synchronization. The rapid-scanning spectrometer was successfully used for multielement determinations, correction of background emission, and characterization of an inductively coupled plasma.

Abstract: The mechanism of the oscillatory phenomena of an underexpanded jet impinging on a flat plate is studied numerically. Pressure changes generated in the flow field near the plate propagate radially in the surrounding region of the jet. The configuration of the jet boundary is changed by them and so, the waves forming the underexpanded jet are displaced when they are reflected from the jet boundary. And then, the pressure disturbances return to the region near the plate. Unsteady flow with repetition of growth and decay of the separation bubble on the plate is also found under certain conditions.

Abstract: KAGRA is the cryogenic interferometric gravitational wave telescope designed for the direct detection of gravitational waves from the astronomical sources. To achieve the best sensitivity, one of the most difficult challenges is cooling the mirrors to 20K to reduce the thermal noise. We developed four cryostats and sixteen very-low-vibration cryocooler units to accomplish our purpose. In this paper, we describe the outline of the cryogenic design and fabrication, and the results of the cryogenic performance test of the cryostats and cryocooler units.

Abstract: The Japanese gravitational wave observatory KAGRA will be operated at cryogenic temperatures to reduce thermal noise. Four main mirrors and their suspension systems, called cryogenic payloads, will be cooled in the cryostat. Vibrations of the cryostat and the cryocooler can contaminate the output of the detector. One of the noise paths is the heat link made from the pure soft metal between the cryogenic payload and cryocoolers to cool the payload. In order to evaluate this noise amplitude, we measured the vibration of the radiation shield at cryogenic temperatures at the cryostat production site in Yokohama, Japan. For this measurement, we developed cryogenic accelerometers. Based on the result of this measurement, we calculated the noise in the KAGRA interferometer. Our results show that with the current design, the seismic noise goal formulated for KAGRA cannot be achieved. Finally, we present a possible design optimization that is meant to reach the nominal sensitivity of the detector.

Abstract: Maldistribution of multidose blood cardioplegia (BCP) continues to be a problem causing perioperative subendocardial damage. However, it is not known whether alpha-adrenergic stimulation contributes to the maldistribution of multidose BCP. We have evaluated the effects of phenoxybenzamine (POB) on multidose BCP distribution, with a right heart bypass model in 14 dogs. Although gradual increases in coronary vascular resistance (CVR) were noted in the control group (CP-1: 0.53 +/- 0.08, CP-2: 0.57 +/- 0.07, CP-3: 0.78 +/- 0.10 mm Hg/ml/min/100 g), there was no significant rise in CVR in the POB group (CP-1: 0.36 +/- 0.03, CP-2: 0.37 +/- 0.04, CP-3: 0.42 +/- 0.04 mm Hg/ml/min/100 g). Improved delivery of BCP was observed in the POB group during CP-3 (endo/epicardial flow ratio 1.72 +/- 0.07 vs. 1.21 +/- 0.18 in the control group; p < 0.05). These data indicate that improved delivery of BCP can be obtained by alpha-adrenergic blockade, if multiple injections of BCP are used for cardiac surgery.

Abstract: We propose a standard stepped sample and specify a procedure for determining the step height for height‐scale calibration of atomic force microscopy (AFM) instruments on the order of sub‐nm to nm. The stepped Si(111) surface structure was confirmed to be the most appropriate for the standard sample by a series of round‐robin measurements carried out by a group comprising AFM instrument manufacturers and user organizations. By specifying a standard measurement procedure, the mean standard deviation of the step heights is decreased by 50%. It is also confirmed that the measured Si step height is accurate to ±5%, which is consistent with the accuracy obtained for higher step standard samples. A prototype common data processing software program containing the algorithm of the specified procedure was used to allow direct comparison of the untreated measurement data from each organization.

Abstract: In interferometric cryogenic gravitational wave detectors, there are plans to cool mirrors and their suspension systems (payloads) in order to reduce thermal noise, that is, one of the fundamental noise sources. Because of the large payload masses (several hundred kg in total) and their thermal isolation, a cooling time of several months is required. Our calculation shows that a high-emissivity coating (e.g. a diamond-like carbon (DLC) coating) can reduce the cooling time effectively by enhancing radiation heat transfer. Here, we have experimentally verified the effect of the DLC coating on the reduction of the cooling time., Comment: 8 pages, 9 figures, Proceedings of CEC/ICMC 2013

Abstract: This paper reports on the optical properties, outgassing rate, and cryogenic performance of surface finishing we have adopted for large optical baffles absorbing stray light in KAGRA, an advanced interferometer for detecting gravitational waves. The surface finishing is based on an electroless nickel-phosphorus-tungsten (NiPW) plating, applicable to large surface area up to ~ 800 mm in diameter, and achieves less than 3% total reflectance against a light beam at 1064 nm with a reasonable scattering distribution ~ 0.05/sr. The outgassing rate from the black coating meets our requirements of 3×10−7 Pa · m3 s−1 m−2. The black coating can tolerate low temperature down to 12 K, and can be installed close to cold mirrors indispensable for the future interferometers.

Abstract: Background : Examination of decayed cavities by means of dental probes has been suggested to destroy decalcified enamel that still may be re-calcified, ultimately causing the development of dental caries. In the present study, we utilized the DIAGNO-DENT caries detector for examination of dental caries. Materials and methods : A total number of 193 teeth of children from eight nursery schools in the Azabu-Akasaka area of Tokyo was examined. The examination procedures consisted of visual observation, data recording, reexamination of teeth diagnosed as C0 and C1, recording of the numerical results, examining the restored teeth and data collection. Results : Dental cavities visually diagnosed as C0 or C1 showed high counting by DIAGNO-DENT examination. The degree of infection was in contrast with DIAGNO-DENT detection. Specifically, there were 12 visually diagnosed C2 that indicated DIAGNO-DENT counting under 18, suggesting that the reference counting 18–25 may not be a definitive indication of cavity preparation. Conclusion : It is possible to conclude that DIAGNO-DENT is noninvasive, easy to use and a reproductive diagnostic method. The use of DIAGNO-DENT for dental cavity detection gives more accurate diagnostic data than the traditional technique.

32. Role of a putative tyrosine-O-sulfate receptor in the targeting and/or intracellular transport of tyrosine-sulfated proteins

Author: M C, Liu, Y, Sakakibara, and M, Suiko
Subjects: Article
Abstract: By employing the affinity gel fraction technique, we have detected a 175 kDa tyrosine-O-sulfate (TyrS)-binding protein in sodium choleate extracts of the microsomal membrane fractions of bovine liver and pancreas, as well as canine liver and pancreas. Western blot analysis revealed the presence of the bovine liver TyrS-binding protein in complexes with tyrosine-sulfated proteins both in vivo and in vitro, suggesting the putative role of the former being the receptor for the latter. Using filter-grown Madin-Darby canine kidney (MDCK) cells as a model, it was demonstrated that the tyrosine-sulfated proteins synthesized were predominantly secreted into the apical medium. The results further indicate the production and differential polarized secretion of different sulfated forms of the two major secretory proteins produced by MDCK cells, fibronectin (FN) and an 80 kDa glycoprotein (gp 80), with their tyrosine-sulfated forms being predominantly secreted from the apical surface. Treatment of filter-grown MDCK cells with glycosylation inhibitors, swainsonine and 1-deoxymannojirimycin, appeared to enhance the apical secretion of tyrosine-sulfated FN and gp 80. A similar 175 kDa membrane-bound 'TyrS receptor', cross-reactive toward antiserum against the canine liver TyrS receptor, was shown to be present in MDCK cells. Pulse-chase experiments revealed its presence in complexes with newly synthesized FN and gp 80. A hypothetical model for TyrS residues serving as an apical targeting signal during the biosynthetic transport of tyrosine-sulfated proteins, as mediated by the TyrS receptor, in MDCK cells is proposed.

Abstract: The Bacillus subtilis alpha-amylase signal peptide consists of 33 amino acids from its translation initiation site. To analyze the structural requirements for efficient processing of the signal peptide, single and repeated Ala-X-Ala sequences and their modifications were introduced into B. subtilis alpha-amylase signal peptides of different lengths and the mature thermostable alpha-amylase. Then the cleavage positions and processing rates of the signal peptides were analyzed by the NH2-terminal amino acid sequences of the exported thermostable alpha-amylases and by in vivo pulse-chase experiments. In B. subtilis, the most efficient cleavage site was located at the peptide bond between Ala-33 and amino acid X at position 34, even though Val-X-Ala and six repeating Ala-X-Ala sequences were present around the cleavage site. However, the cleavage site was shifted to the peptide bond between Ala-31 and amino acid X when Ala-33 was deleted, and it was also shifted to Ala-35 and X when Ala-33 was replaced with Val-33. The shorter signal peptide consisting of 31 amino acids reduced the processing rate and alpha-amylase production. In contrast, those signal peptides were cleaved preferentially at the peptide bond between Ala-31 and amino acid X in Escherichia coli. In addition to the presence of an Ala residue at the -1 amino acid position, the length of the signal peptide was another important requirement for efficient processing.

Abstract: Patch-clamp recording techniques have permitted measurement of the fast Na+ current (INa) in isolated cardiac cells from a number of species in recent years. However, there is still only very little information concerning human cardiac INa. The purpose of this study was to describe the kinetics of INa in normal-appearing, Ca(2+)-tolerant, enzymatically isolated human atrial myocytes using whole-cell voltage-clamp techniques. Atrial specimens were obtained from 46 patients undergoing open heart surgery. Cs+ was substituted for K+ in both pipette and external solutions and F- was added to the former. The reversal potential of the rapid inward current varied approximately 57 mV at 17 +/- 1 degrees C with a 10-fold change in [Na+]o, and the current was completely blocked by 100 microM tetrodotoxin, findings typical of the fast cardiac Na+ current. The tetrodotoxin dose-response curve was best fitted by an equation describing binding to high- and low-affinity sites. INa was activated at a voltage threshold of -70 to -60 mV, and peak inward current was obtained at approximately -30 mV (holding potential, -140 mV). The inactivation time course was voltage dependent and was fitted best by the sum of two exponentials. The relation between voltage and steady-state availability (h infinity) was sigmoidal with the half-inactivation at -95.8 +/- 0.9 mV and a slope factor of 5.3 +/- 0.1 mV (n = 46), and we did not observe a significant difference with disease and age. The overlap of the h infinity and activation curves suggested the presence of a Na+ "window" current. Recovery from inactivation also was voltage dependent and best fitted by a model describing the sum of two exponentials. Recovery occurred after an initial delay at potentials positive to -140 mV, suggesting that inactivation of human atrial INa is a multistate process. We conclude that INa of normal-appearing, Ca(2+)-tolerant human atrial myocytes is similar to that of other mammalian cardiac cells with the possible exception of having two tetrodotoxin binding sites.

Abstract: Harmonic distortion of distributed feedback laser diodes (DFB-LDs) for analog transmission systems is investigated. It is shown that, under a modulation frequency of less than 1 GHz, the harmonic distortion depends on the nonlinearity of the light output power-current (P-I) curve under the continuous wave (CW) condition, which is determined by the coupling constant kappa L, and that the distortion can be minimized at kappa L approximately 1. A 1.3 mu m wavelength InGaAsP DFB-PPIBH (p-substrate partially inverted buried heterostructure) LD and its module, with low distortion by the control of a coupling constant, have been developed. >

Abstract: The low threshold current of 9 mA, the high side-mode suppression ratio of more than 45 dB, the extremely narrow spectral linewidth of 1.1 MHz, and the low chirping of 2.8 AA at -20 dB at 2 Gb/s nonreturn to zero (NRZ) modulation have been achieved in the multiple quantum well (MQW) distributed feedback (DFB) p-substrate partially inverted buried heterostructure (PPIBH) laser diode. The spectral linewidth of 1.1 MHz is the narrowest value among 300- mu m-length solitary laser diodes. These results suggest that the MQW-DFB laser diodes are a promising light source for longer distance and higher bit-rate optical communication systems and coherent optical communication systems. >

45. Oxygen-doped and nitrogen-doped silicon films prepared by molecular beam epitaxy

Abstract: Oxygen-doped and nitrogen-doped silicon films deposited under ultrahigh vacuum were studied for applications in silicon hetero-bipolar transistors (HBTs). It was found through reflection high energy electron diffraction observations that films of SiOx and SiNx can be epitaxially grown for x as high as 0.1. Incorporation of oxygen and nitrogen into the film can be controlled by the substrate temperature and the oxygen or ammonia pressure respectively, and is consistent with previous results of adsorption on the clean silicon surface. The crystalline quality of the films depends on the distance from the epi-substrate interface, and it is better near the heterointerface than in the surface region. HBTs with an SiOx and an SiNx emitter are fabricated using arsenic diffusion from a poly-silicon overlayer for n-type doping, and their test results are described. For improving the HBT characteristics, we have studied in situ arsenic doping into SiOx and SiNx films. The experiment of in situ doping indicates that a high concentration of arsenic prevents oxygen and nitrogen doping.

46. [Epicardial atrial pacing using an active fixation bipolar endocardial lead in children]

Author: M, Noma, N, Atsumi, Y, Hiramatsu, H, Horigome, M, Takahashi, Y, Enomoto, S, Matsushita, and Y, Sakakibara
Subjects: Male, Pacemaker, Artificial, Heart Block, Cardiac Pacing, Artificial, Humans, Infant, Child, Pericardium, Electrodes, Implanted
Abstract: Good performance was observed over 10 years after implantation of bipolar epicardial atrial pacing using an active fixation bipolar endocardial lead in 3 pediatric patients with congenital heart block. The bipolar endocardial lead which was supposed to be fixed transvenously was implanted on the atrial surface by first screwing the lead's helix into the myocardium. The catheter was then laid down on the atrial surface, and both electrodes were wrapped by the atrial tissue. The good performance of this pacing lead seemed to depend on stable positioning of the electrode. This lead is superior to the commercially available, and steroid eluting epicardial bipolar pacing lead, on the point of its small size in head and body, and could be applied to dual chamber pacing in smaller children.

47. Performance test of pipe-shaped radiation shields for cryogenic interferometric gravitational wave detectors

Subjects: Physics, Physics and Astronomy (miscellaneous), Physics::Instrumentation and Detectors, business.industry, Gravitational wave, Detector, Shields, Physics::Fluid Dynamics, Interferometry, Optics, Thermal radiation, Shield, Duct (flow), KAGRA, business
Abstract: One of the most important challenges in cryogenic interferometric gravitational wave detectors is to reduce the undesirable thermal radiation coming through holes in the radiation shield, which are necessary for the laser beam to pass through. For this purpose, pipe-shaped radiation shields called duct shields are used. Here, we have manufactured duct shields for KAGRA in Japan, one of the cryogenic interferometric gravitational wave detectors, and measured the thermal radiation coming through the duct shields. The measured result was found to be consistent with the calculation result that the duct shield can reduce the thermal radiation to less than 1%. This fact confirmed that the amount of thermal radiation coming through the duct shields was smaller than KAGRA?s requirement.

49. Development of a high-efficiency H2 feeder for bioremediation

Author: T, Nobata, M, Prosnansky, Y, Sakakibara, and S, Fukuda
Subjects: Biodegradation, Environmental, Bacteria, Solubility, Water Pollution, Electrochemistry, Water Movements, Soil Pollutants, Electrodes, Waste Disposal, Fluid, Hydrogen
Abstract: An electrochemical dissolved hydrogen feeder equipped with a multi-cathode system and a high-rate recirculation pump was developed in order to examine its feasibility for bioremediation. Results showed that the feeding efficiency was remarkably higher than that in former studies. The reason for the enhanced hydrogen dissolution rate was thought to be due to the large cathode area by applying multiple granular activated carbon electrodes resulting in low current density. Two mass balance equations were formulated and applied to analyze the performance of the apparatus theoretically. The hydrogen dissolution rate calculated from the equations was in fairly good agreement with observed results. It was suggested that the electrochemical H2 feeder would be a competitive alternative as a hydrogen feeding method for bioremediation.
