Abstract:

After the accident at the Fukushima Daiichi Nuclear Power Plant following the Great East Japan Earthquake, the future promotion of nuclear power generation has been discussed from various points of view. Ensuring national security requires down-toearth policies on energy as well as on defense and food supplies, together with diplomatic efforts and technologies that realize these policies. In the author’s opinion, in view of Japan’s poor fossil fuel resources and a worldwide increase in energy demand, particularly among emerging countries, nuclear power generation should be maintained with all possible measures taken to ensure safety until alternative power generation methods are developed that provide excellent safety, stability, and economy. Therefore, in light of the lessons learned from the experience of the Fukushima accident, the problems identified should be carefully examined and improvements should be made to revitalize nuclear power generation in Japan. With this awareness in mind, this article discusses the concept of the social responsibility of engineers and managers, i.e., the meaning of a sense of responsibility and compliance with laws and norms for business personnel, through personnel at Tohoku Electric Power Co., Inc., (Tohoku Electric) at the time of the Great East Japan Earthquake and achievements by the late Yanosuke Hirai, a former vice president of the company, who greatly influenced decisions on the premise height of the Onagawa Nuclear Power Plant. Nowadays, the statements of engineers, policymakers, and managers are viewed less reliable than before. In such circumstances, reviewing the words and deeds of Mr. Susumu Yoda, a former vice president of Tokyo Electric Power Co., Inc., (Tepco) who was involved in promoting nuclear power generation, we discuss the concept of the social responsibility of those involved in megatechnology. Finally, the author highlights a current question involving a basic problem regarding the concept of decision making in relation to problems including scientific uncertainty, and discuss the direction in which to proceed.

Abstract:

A creative robot contest for decommissioning was held as part of human resources development for decommissioning of the Fukushima Daiichi Nuclear Power Station of Tokyo Electric Power Co., Inc. In the 5th creative robot contest for decommissioning, robots were developed for fuel-debris retrieval from the lower part of the pedestal. Fukushima KOSEN developed a robot consisting of a primary robot that moves to an access port on the platform while a secondary robot is stored inside the main body. The robot collects fuel debris by lowering the secondary robot 3.2 m downward. Fukushima KOSEN also developed a graphical user interface (GUI) to visually express the motion of the robot.

Abstract:

We are very honored to receive the prestigious JDR Award for the Most Cited Paper 2022. The winning paper, “Real-Time Tsunami Prediction System Using DONET,” discusses a system that uses data from the Dense Oceanfloor Network system for Earthquakes and Tsunamis (DONET), which was installed in the rupture areas of the 1944 Tonankai and 1946 Nankai earthquakes in order to instantly generate and visualize tsunami prediction information. The forecast information from this system consists of tsunami arrival time, maximum tsunami height, tsunami inundation area, and inundation depth distribution. The system, which visualizes and distributes forecast information for areas where users need it as a supplement to the tsunami information provided nationwide by the Japan Meteorological Agency, has been introduced in Wakayama Prefecture, Mie Prefecture, Chiba Prefecture, and the city of Owase, as well as by Chubu Electric Power Co., Inc. After DONET was installed in the Tonankai rupture area, we were considering the possibility of using DONET data regionally, and we developed the system as results of discussions with Wakayama Prefecture and Chubu Electric Power Co., Inc. Under the concept that the users themselves would be operating the system, we intended to make the system as simple and easy to understand as possible, and to reduce costs by minimizing the number of hardware units. We also considered making the system flexible and scalable, recognizing that each user has a different way of how to use the tsunami forecast information. We were able to receive this award thanks to the cooperation of the people who were involved in many discussions with us during the process of establishing the concept. We will not become complacent going forward, but will continue to improve our system in ways that reflect the opinions of the users. We would like to thank everyone who has cited this paper with their interests.

Abstract:

It is very essential to raise the thermal efficiency of combined cycle plants from the viewpoint of energy saving and environmental protection. Tohoku Electric Power Co., Inc., and Toshiba Corporation in Japan have jointly studied the next generation of combined cycle systems using 1500°C class gas turbine. A promising cooling technology for the vanes using steam was developed. The blades are cooled by air, adopting the impingement cooling, film cooling, and so on. The cooling effectiveness was confirmed both for the vanes and the blades using a hot wind tunnel. This paper describes the design features of the vanes and the blades, and the results of the verification tests using the hot wind tunnel.

Abstract:

Abstract Background GB004 is a small molecule that stabilizes hypoxia inducible factor (HIF-1α), a key transcription factor involved in the cellular responses at the intersection of hypoxia and inflammation. GB004 induction of HIF-1a target genes improves barrier integrity and reduces barrier permeability in rodent models of colitis. Here we investigated gene expression and secretion of soluble factors elicited by GB004 treatment on immune cells and epithelial cells, human monolayer assays and immune co-culture studies to further explore its protective mechanism. Methods In the BioMAP human co-culture assay, cells were treated with GB004 one hour prior to stimulation and incubated for 24–168 hours. Biomarkers, cell viability and proliferation were assessed. Repligut human stem-cell-derived monolayer platforms were used to assess GB004 effects under unstimulated or TNFa stimulation conditions. Barrier integrity was assessed by Transepithelial Endothelial Electric Resistance (TEER), HIF-1a target genes were assessed in cell lysates, and tight junction formation and epithelial monolayer viability were investigated by immunofluorescence staining. Results GB004 demonstrated activity in 11 of 12 systems in the BioMAP human co-culture assay, which covers a range of disease-relevant immune and non-immune mechanisms under stimulation conditions. Collectively, GB004 treatment led to changes in biomarkers associated with inflammation (sTNFa, IL-8, MCP-1, CXCL11), immunomodulation (sIL-17F, sIL-17A), and tissue remodeling (collagen I, collagen IV). GB004 treatment also reduced the proliferative activity in the in vitro lymphocyte assay systems. In the human Repligut intestinal epithelium assay, GB004 significantly reduced cell death and improved barrier integrity in response to pro-inflammatory cytokines. The protective role of GB004 on barrier integrity was further supported by immunostaining experiments demonstrating that GB004 treatment protected epithelial cells from TNFa-induced cell apoptosis, improving both epithelial cell number and tight junction protein ZO-1 staining. Conclusion GB004 modulates key anti-inflammatory and immunomodulatory activities in human co-culture systems. Furthermore, GB004 demonstrates protective effects on human derived monolayer cultures by reducing cell death, promoting tight junction formation, and improving barrier integrity. Targeting both barrier function and local colonic inflammation represents a multi-faceted approach to treatment of inflammatory bowel disease. A phase 2 clinical study of GB004 is ongoing in patients with ulcerative colitis (NCT04556383). Sponsored by GB004, Inc., a wholly owned subsidiary of Gossamer Bio, Inc.

Abstract:

In 1978, the Japanese government started a national project for energy conservation called the Moonlight Project. The Engineering Research Association for Advanced Gas Turbines was selected to research and develop an advanced gas turbine for this project. The development stages were planned as follows: first, the development of a reheat gas turbine for a pilot plant (AGTJ-100A), and second, a prototype plant (AGTJ-100B). The AGTJ-100A has been undergoing performance tests since 1984 at the Sodegaura Power Station of the Tokyo Electric Power Co., Inc. (TEPCO). The inlet gas temperature of the high-pressure turbine (HPT) of the AGTJ-100A is 1573 K, while that of the AGTJ-100B is 100 K higher. Therefore, various advanced technologies have to be applied to the AGTJ-100B HPT. Ceramic coating on the HPT blades is the most desirable of these technologies. In this paper, the present level of development, and future R & D plans for ceramic coating, are taken into consideration. Steam blade cooling is applied for the IGSC.

Abstract:

Shikoku Electric Power Co., Inc. has developed the technology to manufacture a brand name "Finash" about 12 years ago, by sorting and classifying coal ash generated in coal fired power plants. "Finash" is highly functional fly ash (HFA) is produced by removing irregular coarse particles. It is important for the production of HFA to minimize the variation in quality of coal ash with sophisticated classification technique and extracting good-quality spherical fine particles. It is now widely utilized as concrete admixture for general civil engineering structures and buildings in Japan. When highly functional fly ash (HFA) is used as shotcrete admixture to substitute for fine aggregate of 100kg/m3, the shotcrete has the advantages of decreasing the amount of dust and rebound during spraying operation, improving the hardened properties of concrete, etc. Therefore, it has been applied in many tunnel construction projects. This paper discusses about the various characteristics such as construction placement, strength, neutralization and dry shrinkage of shotcrete using highly functional fly ash (HFA), using the results that is obtained from spray test in an actual road tunnel.

Abstract:

It has been almost 10 years since the accident at Tokyo Electric Power Co., Inc.’s Fukushima Daiichi Nuclear Power Plant in March 2011. This study elucidates changes in the mental states of mothers and children residing in low-dose radiation contaminated regions within Fukushima Prefecture over a five-year period after the Fukushima Daiichi accident. From 2011 to 2015, questionnaire surveys assessing psychological symptoms, including posttraumatic stress disorder-related responses, depressive responses, and stress responses, and radiation protection behaviors were conducted with 18,741 mothers of children aged four, 18, and 42 months. Mothers’ and children’s psychological symptoms and mothers’ radiation protection behaviors were highest in 2011, immediately following the nuclear accident, but decreased over time. However, even in 2015, psychological symptoms and radiation protection behaviors were higher for children and mothers within Fukushima Prefecture than for those in a control group living in regions outside the area, which were minimally affected by the accident. The results suggest that the psychological effects in mothers and children living in low-dose radiation contaminated areas continued for at least five years after the accident. Furthermore, psychological effects in children born after the incident were likely to have been triggered by the parental behavior of mothers who were negatively affected by anxiety and stress. This finding raises concerns regarding the accident’s long-lasting psychological effects in mothers and children living in low-contamination regions.

The purpose of this study was to explore the psychoneuroimmunologic effect of aromatherapy massage and to compare the effect with that of massage. This study is designed as a nonequivalent control group pretest-posttest quasi-experimental study and each twenty postpartum mothers volunteered the experimental group and control group. For experimental group, researcher used massage with 2% Jojova oil mixed with Lavender and Rosemary oil (Bush Boake Allen Inc., USA) for 20 minutes, whereas for control group Jojova oil was used as luburicant for massage. Skin temperature was measured with YSI Tele-thermometer(Simpson electric Co., USA) and the concentration of IgA in salivary was analyzed by immunoturbididimeter assay(Cobas INTEGRA, Roche, Swiss) at pre and post test. Also at this time fatigue were measured by Rhoten Fatigue Scale through self-report. The data were analyzed using SAS and hypothesis was tested with unpaired t-test. The results were as follows : 1) Score of fatigue decreased significantly after use of aromatherapy massage. 2) Skin temperature increased significantly after use of aromatherapy massage. 3) Concentration of salivary IgA increased significantly after use of aromatherapy massage. In conclusion, from the standpoint of psychoneuroimmunologic view, the results suggest that aromatherapy massage have greater effect compared with massage and can be effective nursing intervention to enhance relaxation of mind and body in the postpartum mothers.

Abstract:

Tetraploid complementation has been extensively used to verify the pluripotency of stem cells and also for improving placenta formation when tetraploid embryos are aggregated synchronously or asynchronously with diploid (2n) embryos. Generation of tetraploid embryos can be achieved by the electric fusion of a 2-cell embryo. However, the optimal electric intensity pulse to generate tetraploid embryos has not been studied in the feline. The aims of this study were to (1) evaluate the optimal fusion conditions to achieve the highest fusion rate without affecting embryo developmental competence, (2) compare the in vitro development of synchronic and asynchronic aggregated domestic cat IVF embryos, and (3) assess pre-implantation development of embryos generated by asynchronic complementation of presumptive 1-cell tetraploid embryos with diploid blastomeres. Domestic cat cumulus-oocyte complexes were matured in vitro on 21% O2 in air at 38.5°C for 22h. The IVF embryos were generated by co-incubation of in vitro-matured oocytes with 2×106 motile spermatozoa mL−1 on 21% O2 in air at 38.5°C for 18 to 20h. After 24h of IVF, 2-cell embryos were selected. For Experiment 1, membrane fusion of 2-cell IVF embryos (n=164) was performed with two 30-ms DC pulses at different electric field (0.8, 2, 4, and 8 kV/cm) in fusion media (Mannitol, MgSO4, CaCl2, and polyvinyl alcohol). Presumptive fused embryos and nonfused were cultured in vitro in 50-µL drops of modified Tyrode’s medium on 6.5% CO2 in air at 38.5°C (Pope et al. 2006 Methods in Molecular Biology 254, 227-244). Cleavage was determined 24h after pulse. For Experiment 2, zona pellucida-free IVF embryos (n=110) were synchronically (two 4-cell embryos) or asynchronically (one 4-cell embryo and one 2-cell embryo) aggregated in 1 microwell. For Experiment 3, 1-cell presumptive tetraploid embryo (2-cell fused embryo) was asynchronically complemented with a 4-cell embryo (n=38). For all experiments, blastocyst stage was evaluated at Day 8, and embryos presenting more than one structure per microwell were considered non-aggregated. Data were analysed by Fisher’s exact test using GraphPad Prism 6.0 (GraphPad Inc., San Diego, CA, USA), and differences were considered significant at P<0.05. The highest fusion rates (30 and 46%) with the best developmental competence (31 and 46%) were observed with 4 and 8 Kv/cm electric pulses, respectively. Electric fusion did not affect the embryo developmental competence. We observed that synchronic and asynchronic complementation reached similar blastocysts rates (54 and 65%, respectively), indicating that both techniques are suitable for tetraploid embryo complementation. Finally, when presumptive tetraploid embryos were asynchronically complemented with diploid blastomeres, the high blastocyst rate (90%) was obtained from embryos that form only one structure (aggregated embryos). Further experiments will be performed to track the distribution of cells using mitotrackers after complementation using tetraploid IVF and diploid somatic cell nuclear transfer embryos.

Abstract:

Cryopreservation of porcine blastocysts is regarded as a demanding task because of the high chilling sensitivity and low survival rates. Ultrarapid vitrification techniques combined with the previous artificial induction of collapse of the blastocoel have been successfully applied in mouse and human. The purpose of our work was to use the Cryotop (Kitasato Supply Co., Tokyo, Japan) vitrification method combined with induced blastocyst collapse for cryopreservation of porcine blastocysts produced with parthenogenetic activation of in vitro-matured oocytes. A total of 1200 slaughterhouse-derived porcine oocytes were matured for 41–42 h. Zona-intact or zona-free oocytes (after pronase digestion) were activated with a single electric impulse of 63 or 43 V cm–1, respectively, and incubated in 5 μg mL–1 cytochalasin B and 10 μg mL–1 cycloheximide for 4 h (Du et al. 2007 Cryobiology 54, 181–187). Embryo culture was performed in PZM-3 medium (Yoshioka et al. 2002 Biol. Reprod. 66, 112–119) in 5% CO2, 5% O2, and 90% N2 and maximum humidity. On Day 6, collapse was induced manually in approximately half of the blastocysts with the use of a fire-polished holding pipette and injection pipette (Cook Australia, Brisbane, Queensland, Australia). Ten min after the manipulation, collapsed and control (not manipulated) blastocysts were vitrified with the Cryotop, and then warmed and diluted in 1, 0.5, and 0 m sucrose, respectively (Kuwayama et al. 2005, Reprod. BioMed. Online 11, 300–308). Reexpansion of blastocysts was evaluated under a stereomicroscope after 16–18 h of culture under conditions described above. SPSS 11.0 program (SPSS, Inc., Chicago, IL, USA) was used for statistical calculations; values with P < 0.05 were regarded as significant. Reexpansion rates of blastocysts are shown in Table 1. Our results indicate that manually induced collapse of the blastocoel increases reexpansion rates of both zona-intact and zona-free porcine blastocysts after Cryotop vitrification. The combination of these simple techniques may help to improve the efficiency of cryopreservation of pig embryos for both experimental and practical applications. Table 1.

Abstract:

The kinetics of hydrogen evolution reaction on cobalt monosilicide CoSi in potassium hydroxide solution was studied using methods of polarization and impedance measurements. Electrochemical impedance of CoSi was studied in 1 M KOH at 21-22 °C in the range of potentials of hydrogen evolution. Solutions were prepared from high-purity reagents and de-ionized water (Milli-Q). The working solutions were de-aerated with hydrogen (purity 99.999 %). Cobalt silicide was prepared from silicon (99.99 % purity) and electrolytic cobalt (99.98 % purity) by Czochralski method (pulling from the melt at speed of 0.4 mm/min). Electrodes were cut using electric-spark method. The working electrode surface was 0.4 – 0.6 cm2. Before measurements, the working electrode surface was abraded with emery papers of 1000 and 2000, cleaned with ethanol and washed in the working solution. Electrochemical measurements were carried out in three-electrode electrochemical cell with cathodic and anodic compartments separated with a porous glass diaphragm. Potentials Е were changed from low to high cathodic polarisations and vice versa. Before recording an impedance spectrum at each potential value, the electrode was polarised under potentiostatic conditions until constant value of current was reached. The electrode potentials are given with respect to the SHE. Impedance measurements were carried out using FRA Solartron and potentiostat Solartron 1280 (Solartron Analytical) in the frequency range from 10 kHz to 0.01 Hz (10 points per decade). The alternating signal amplitude was 10 mV. The CorrWare2, ZPlot2 and ZView2 software (Scribner Associates, Inc.) was used for measuring and processing the impedance data. In 1 М KOH polarization curve for CoSi-electrode has Tafel plot with the slope bk = 0.113 V. Earlier it was established that b for Со2Ѕі and CoSi2 at these conditions were 0.123 and 0.105 V, respectively, while b for Co was equal to 0.144 V. Tafel slope for cobalt monosilicide is less than Co, i.e. the difference between the current densities on the silicide and cobalt increases with increasing in cathodic polarization. At a constant electrode potential E, the current density i for CoSi is higher than for Co (at E = -1.2 V the value of i for CoSi is equal to 1.58 mA/cm2, and for Co i = 0.32 mA/cm2). Nyquist diagrams consist of the combination of capacitive semicircle at high frequencies and an inductive arc at low frequencies. Impedance spectra of cobalt silicide can not be accurately described by a simple equivalent circuit consisting of parallel-connected charge transfer resistance and the double layer capacitance. In order to describe the behavior of CoSi - electrode in 1 M KOH solution in the range of investigated potentials the equivalent circuit was used which was obtained in several works as a model of two-stage process with the adsorption of intermediate substances, in particular for hydrogen evolution reaction. In order to analyze the impedance data we used the diagnostic criteria for hydrogen evolution reaction mechanisms, based on the dependence of equivalent circuit elements on the overvoltage and OH- ions concentration, which were previously proposed. Determination of the kinetic parameters (rate constants and transfer coefficients) of hydrogen evolution reaction steps on the basis of the impedance data has been considered. Hydrogen evolution reaction on CoSi electrode in alkaline solution is discussed using the proposed criteria. It has been shown that hydrogen evolution reaction on CoSi in potassium hydroxide solution proceeds through the Volmer-Heyrovsky route with Heyrovsky reaction as the rate-determining and with the Langmuir isotherm for hydrogen adsorption.

Abstract:

Humankind is currently facing a global transition towards a green electrification of both energy production and transportation. There is an urgent need to find new approaches for the storage of energy derived from renewable sources, such as solar irradiation, wind and waves. In addition, electric cars require energy storage or conversion systems capable of providing engine power. To these ends, secondary batteries are an attractive and viable solution, especially in the form of the relatively mature Li-ion technology. Unfortunately, Li power sources suffer from high cost, low Li earth-crust abundance, and toxicity of their electrochemical components (e.g., the Co-based cathodes). Such disadvantages demand the exploration of new energy storage devices based on alternative chemistries (e.g., Na, Mg, Ca). Since their discovery [1-5], electrolytes based on disordered or delta metal halide salts (e.g., δ-MgCl2, δ-LiCl, δ-MgI2) have received widespread attention due to their intriguing physical-chemical properties. Subsequently, electrolytes comprised of ionic liquid solvents dispersing various δ-metal halide salts were investigated [6-9]. These latter ion-conducting systems are characterized by: (i) very high room-temperature ionic conductivity; (ii) wide thermal, chemical and electrochemical stability; and (iii) high coulombic efficiency and very low overpotentials in the metal deposition and stripping processes. In this contribution, a comparison of different families of ionic liquids will be proposed. In particular, the effects of the use of δ-metal halide salts (e.g., δ-MgCl2, δ-LiCl, and δ-NaCl) on the thermal stability, vibrational features, and electrochemical properties of the resulting electrolytes will be considered. The conductivity mechanisms will be analyzed side-by-side, revealing how ionic conductivity is modulated by the metal ions (e.g., Mg2+, Li+, Na+), on the basis of broadband electrical spectroscopy results.

Abstract:

Abstract Despite the fact that simple interventions and emerging therapies can increase survival of SCD patients, under detection renders SCD a major cause of under age-5 mortality in rural regions of the developing world where it is prevalent. (Piel et PLoS Med DOI: org/10.1371/journal.pmed.1001484, 2013). Two major diagnostic challenges are: 1. A lack of affordable diagnostic methodology to obtain point-of-care results in low-resource environments. 2. Dispersion of SCD patients in vast rural hinterlands who rarely interface with healthcare services. To address the first impediment, we have developed and validated a simple, low-cost test to screen for SCD using aqueous multiphase systems (AMPS). AMPS are solutions of polymers and surfactants that form immiscible self-assembling step-gradients. An AMPS designed to target the density signature of sickle cell anemia forms the basis of this novel diagnostic technique. (Kumar et al, PNAS DOI:10.1073/pnas.14147391110, 2014). Building on a design previously tested in Zambia (Kumar et al, PLoS One DOI: 10.1371/journal.pone.0114540, 2014) an improved test has been developed and named "Mpana" for "Multi-Phase Analyzer." The Mpana test detects the presence or absence of cells with a high mass-density as an indirect method to test for the presence of sickled cells. The test uses 5 µL of fingerstick blood, can be performed in 15 minutes using an inexpensive ($150), battery-powered centrifuge, the results can be read with the naked eyes by a trained reader (Figure 1) and costs 50 cents per test. The improved density-based test was first verified on fingerstick samples in the U.S. before being validated in a field study in rural Zambia. To manage the access difficulty of large-scale rural SCD screening, we exploited a partnership with the National Zambian Dental Training School. We have previously demonstrated that provision of free toothbrushes, toothpaste and other minimal health services is a powerful magnet to attract subjects in rural regions of Zambia that have high rates of tooth decay. Once collected these individuals can receive other healthcare interventions such as SCD screening. We conducted a cross-sectional field test of this approach in August and September of 2017 in the rural Serenje and Chitambo Districts of Northern Zambia. A local drama group and radio and mobile broadcasts informed the target communities about the dental intervention that attracted over 700 subjects. Of these, 503 children aged 1 month to 18 years were symptom screened for SCD, tested with MPANA, and dried blood spot (DBS) samples collected. The DBS were analyzed by iso-electric focusing and high-performance liquid chromatography at the New England Newborn Screening Program. Of the screened subjects, 78 had sickle cell trait and 17 had SCD. A score was assigned to visual readings of the MPANA test to enable ROC analysis.The ROC curve shows good diagnostic performance with an area under the curve (AUC) of 0.84. (Figure 2) The MPANA test had a sensitivity of 71% (CI 47-88%) and a specificity of 99% (CI 98-100%), with an overall diagnostic accuracy of 98% (CI 97-99%). Importantly, the MPANA test had a negative predictive value of 99% (CI 98-100%). Combining Mpana results with a clinical symptom score yielded a slightly improved specificity of 100% (CI 99.5-100%) and yielded an overall diagnostic accuracy of 99% (CI 98-100%). In conclusion, a multidisciplinary consortium has achieved the first validation of a low-cost simple point of care test to diagnose SCD in a rural area of a developing nation and has demonstrated the ability of dental services to facilitate such screening. Offsetting the theoretical concern that the MPANA test might not detect SCD in neonates and young infants due to their high hemoglobin F content are the advantages that our SCD screening strategy is low cost, primarily utilizes local resources and immediately delivers positive subjects to care interventions (which could be anything in addition to or other than SCD screening). It is therefore amenable to scaling up for widespread application.
