In this study, we report a two-dim.nsional (2D) hexagonal disk obtained by carbonization of Botryococcus braunii (B. braunii) residues. Carbonization at 700℃followed by naturally cooling down to room.tem.erature under a non-inert gas flow atm.sphere affords to yield this unique structure. The 2D hexagonal disks consist of m.re than 52% carbon and m.re than 25% oxygen. Slight am.unt of Fe, silicon and m.gnesium.would be the trigger of the form.tion of hexagonal structure. Treatm.nt of biom.ss residue is a challenge in the near future accom.anied by the achievem.nt of new energy technology in the industrial level. This research points out that efficient use of discharged biom.ss residue could create a new avenue for m.terial science. The m.rphology of obtained crystals carbonized in different conditions, especially with the existence of argon flow, was also investigated.

Purpose: To determ.ne if nurses are able to identify m.dication errors that have the potential to bypass com.uter physician order entry (CPOE) and sm.rt ordering system.. Background: m.dical care system. em.loy com.uter “sm.rt” system. to reduce m.dication errors by using artificial intelligence (preprogram.ed m.thods of decision support and error reduction). However, these system. are not perfect and they can be bypassed. Nurses who carry out the order represent the last check point in error prevention prior to the adm.nistration of m.dication orders. m.thods: A paper exercise was created with 513 physician orders. Nurses were asked to indicate whether they would carry out the order, refuse to carry out the order, consult a pharm.cist for clarification, or carry out the order with special precautions. Nurses were given the option of using any nursing or m.dical reference. Results: The rate of correctly identifying 23 of the contraindicated orders was low. Both experienced and inexperienced nurses had high rates of not identifying the errors despite sim.lar use of references and requests for assistance from.pharm.cists. Conclusions: This study dem.nstrates that if an error escapes a sm.rt system. nurses were able to identify m.st of these errors, but not all of these. The current system.features high stress, self-esteem.issues, tim. pressure, high volum., and high risk. The system.m.st change radically to m.et the public’s expectations of being nearly error free which can only be achieved with sm.rter system. that are m.re resistant to hum.n errors.

在日本国家发展课题DIOS基础上,双联-DIOS过程实现了工程化,并已在综合的和小钢铁厂生产应用.双联-DIOS中,采用了转底炉(RHF),多床炉(m.F)或其他采用煤的直接还原设备作为预还原装置,而不采用流化床型预还原炉,它只用于开始的DIOS中.周期加入DIOS的熔炼炉SRF中的预还原铁矿石,其还原度(50%～70%)要比开始DIOS中加入的还原度(小于30%)高得多.因而,双联-DIOS的生产率显著高于开始的DIOS.考虑到预还原特点,材料的品级和钢铁厂的能量平衡等方面的优点,本课题的目标才得以实现.

Water outlets for washing hands and m.dical equipm.nt are essential for preventing hospital infection. The present study clarified the effects of water flow volum. on the identification and quantitative evaluation of bacteria found around spouts in the 17 hand-washing stations. Pseu-dom.nas aeruginosa was detected from.4 sta-tions before adjustm.nt and 2 after adjustm.nt. Although no significant difference was identified in the detection rate of P. aeruginosa (p = 0.368), when com.ining P. aeruginosa and glucose non-ferm.ntative Gram.negative bacilli (NFB), the num.er of stations with P. aeruginosa and/or NFB decreased significantly from.15 before adjustm.nt to 9 after adjustm.nt (p = 0.023). Before adjust-m.nt, quantity of bacteria was “2+” for 3 stations and “1+” for 7 stations, but was “1+” for 3 stations and “2+” for 0 stations after adjustm.nt. These results show that quantity of bacteria could be reduced from.spouts by adjusting flow volum.. These results were also supported by experim.nts for cleanliness using Adenosine 5’-triphosphate biolum.nescence m.- thod.

＜正＞ Thalli of Oedogonium.bia Liu et Hu and Oedocladiutn prescottii Islam.collected from.terrestrial places have been cultivated for m.re than two year in the laboratory of Institute of Hydrobiology at Wuhan in China. In both species of the term.nal cell division produced the apical cap attaching laterally to a septum.between term.nal cell and sub-term.nal cell in a filam.nt observed under the light m.croscope and electronic m.croscope. It was easier to find the attaching apical caps in filam.nts from.culture m.terial than from.field m.terial. It was the first record of the apical cap structure in genus Oedogonium. Several new observations were recorded in both species. The m.in differences between term.nal cell division and intercalary division had been studied in Oedogoniales. The sub-term.nal cell, com.ng from.the term.nal cell, with apical cap could not divide again, but one intercalary cell could divide a few tim.s, resulting as a series of rings on its cell wall. Thallus of Oedogonium.bia was an un-branched filam.nts with intercalary division, sim.ltaneously the cell grown m.inly by the term.nal cell division, which also occurred in Oedocladiurn,. m.ybe Oedogonium.bia was considered to be an evolutionary m.ddle representative between Oedogonium.and Oedocladium.

Purpose: Um.m. reportedly prom.tes salivation. We aim.d to investigate the effects of taste stim.li on slow and fast salivary secretion in hum.ns using um.m., sweet, and sour stim.li. m.thods: Eight healthy wom.n participated between 14:00 and 15:00, taking the circadian rhythm.of salivary secretion into account. The types and concentrations of the taste solutions were glutam.c acid (1.7 × 10−3 m., inosinic acid (9.8 × 10−3 m., and guanylic acid (9.8 × 10−3 m. for um.m. stim.lation, citric acid (6.5 × 10−3 m. for acidity stim.lation, and sucrose (1.6 × 10−2 m. for sweetness stim.lation. First, the unstim.lated salivary flow rate was m.asured. Then, 3 m. of a flavor solution was dropped under the tongue using a syringe. The saliva was expelled into an alum.num.cup every m.nute and weighed. The first m.nute’s value m.nus 3 m. flavor solution was the stim.lated salivary secretion rate produced by each flavor. The tim.-to-return to the initial unstim.lated salivary flow rate was the duration of the stim.lated saliva secretion rate. Results: The m.an unstim.lated salivary flow rate across participants was 0.64 ± 0.25 m./m.n (range: 0.23 - 1.03 m./m.n). The highest am.unt of saliva was induced by citric acid. There were significant differences between citric acid and the other flavor solutions (p m.c acid, inosinic acid, and sucrose;p m./m.n) and fast groups (0.83 ± 0.15 m./m.n) based on their m.dian resting salivary secretion rate, there were no significant differences between the two groups in the am.unt of saliva secreted at 1 m.nute after stim.lation and the duration of the salivary secretion rate. Conclusion: Um.m. stim.lation was effective in slowing salivary secretion and sustaining salivary secretion after stim.lation.

In recent years, graphene field-effect-transistors(GFETs) have dem.nstrated an outstanding potential for terahertz(THz) photodetection due to their fast response and high-sensitivity. Such features are essential to enable em.rging THz applications, including 6G wireless com.unications, quantum.inform.tion, bioim.ging and security. However, the overall perform.nce of these photodetectors m.y be utterly com.rom.sed by the im.act of internal resistances presented in the device, so-called access or parasitic resistances. In this work, we provide a detailed study of the influence of internal device resistances in the photoresponse of high-m.bility dual-gate GFET detectors. Such dual-gate architectures allow us to fine tune(decrease) the internal resistance of the device by an order of m.gnitude and consequently dem.nstrate an im.roved responsivity and noise-equivalent-power values of the photodetector, respectively. Our results can be well understood by a series resistance m.del, as shown by the excellent agreem.nt found between the experim.ntal data and theoretical calculations. These findings are therefore relevant to understand and im.rove the overall perform.nce of existing high-m.bility graphene photodetectors.
