Short-term tidal and diel variations of autumn fish assemblage in a Zostera marina bed were investigated using 3 h interval samplings for 24 h in both spring and neap tide using a small beam trawl.A total of 1 346 fishes belonging to 19 species were collected at spring tide,whereas 1 115 fishes belonging to 17 species were at neap *** common fish species were Nuchequula nuchalis,Acanthogobius flavimanus,Takifugu niphobles,Acentrogobius pflaumii,and Pholis nebulosa with the former three species dominating at spring tide,while the latter two species being abundant at neap *** variation in abundance was significant with higher abundance at night than day,but there were no significant differences between spring and neap tides,and between ebb and flood tides（three-way ANOVAs）.Diel variation in the abundance of fishes may be influenced by tidal range and cycle,and day-night differences of food availability and behaviors of fishes ***-metric multidimensional scaling（n MDS） ordination and analysis of similarity（ANOSim） results revealed significant differences in species compositions both between day and night,and between spring and neap *** beds are highly productive marine ecosystem,and thus,our results will contribute to conservation of seagrass ecosystem in the study area.

Zero-static-power nonvolatile logic-in-memory circuits for flexible electronics

Flexible logic circuits and memory with ultra-low static power consumption are in great demand for battery-powered flexible electronic systems. Here, we show that a flexible nonvolatile logic-in-memory circuit enabling normally-off computing can be implemented using a poly（1,3,5-trivinyl-l,3,5-trimethyl cyclotrisiloxane）（pV3D3）-based memristor array. Although memristive logic-in-memory circuits have been previously reported, the requirements of additional components and the large variation of memristors have limited demonstrations to simple gates within a few operation cycles on rigid substrates only. Using memristor-aided logic （MAGIC） architecture requiring only memristors and pV3D3-memristor with good uniformity on a flexible substrate, for the first time, we experimentally demonstrated our implementation of MAGIC-NOT and -NOR gates during multiple cycles and even under bent conditions. Other functions, such as OR, AND, NAND, and a half adder, are also realized by combinations of NOT and NOR gates within a crossbar array. This research advances the development of novel computing architecture with zero static power consumption for battery- powered flexible electronic systems.

Removal of primary iron rich phase from aluminum-silicon melt by centrifugal separation

引用

China Foundry 2013年第2期10卷 112-117页

作者： seong Woo Kim Un Ho im Hyeong Cheol Cha Se Hyeong Kim Ji Eun Jang Ki Young Kim School of Energy Materials and Chemical EngineeringKorea University of Technology and Education

Recycling is a major consideration in continued aluminum use due to the enormous demand for high quality products. Some impurity elements gradually accumulate through the repetitive reuse of aluminum alloy scrap. Of them, the iron content should be suppressed under the allowed limit. In the present research, a novel separation method was introduced to remove primary iron-rich intermetallic compounds by centrifugation during solidification of AI-Si-Fe alloys. This method does not use the density difference between two phases as in other centrifugal methods, but uses the order of solidification in AI-Si-Fe alloys, because iron promotes the formation of intermetallic compounds with other alloying elements as a primary phase. Two AI-Si-Fe alloys which have different iron contents were chosen as the starting materials. The iron-rich phase could be efficiently removed by centrifuging under a centrifugal force of 40 g. Coarse intermetallic compounds were found in the sample inside the crucible, while rather fine intermetallic compounds were found in the sample outside the crucible. Primary intermetallic compounds were linked to each other via aluminum-rich matrix, and formed like a network. The highest iron removal fraction is 67% and the lowest one is 7% for AI-12Si-1.7Fe alloy. And they are 82% and 18% for AI-12Si-3.4Fe alloy, respectively.

OBJECTIVE: To collect preliminary data on the effects of Saam acupuncture with regard to the immunity in cancer ***: Ten cancer patients were analyzed for improvements in immunity. Acupuncture was applied at the 5 acupuncture points, Jingqu(LU 8), Zutonggu(BL 66), Yanggu(SI 5), Yangchi(TE 4), and Zhongwan(CV 12) for 2 weeks with 4 sessions. We assessed the effect of Korean Saam acupuncture on the immune system in cancer patients by measuring particular blood cell subsets, including CD3 +,CD4+, CD8+, CD19+, and CD56+ cells, as well as total white blood cell count, absolute neutrophil count, and fatigue score. The measurement was performed before and after acupuncture and at a 2-week ***: There was a statistically significant increase in the number of CD3+(P=0.023) and CD8+ cells(Pimprove the immune system by increasing the counts of a few immune cells and relieve fatigue in cancer patients by decreasing FSS scores. Although this was a non-controlled study, it constitutes preliminary research investigating the potential effects of Saam acupuncture in increasing the counts of several immune cells in cancer patients.

Effect of gastric acid suppressants and prokinetics on peritoneal dialysis-related peritonitis

Aim: To investigate the effect of gastric acid suppressants and prokinetics on peritonitis development in peritoneal dialysis(PD) ***: This was a single-center, retrospective study. The medical records of 398 PD patients were collected from January 2000 to September 2012 and analyzed to compare patients with at least one episode of peritonitis(peritonitis group, group A) to patients who never had peritonitis(no peritonitis group, group B). All peritonitis episodes were analyzed to compare peritonitis caused by enteric organisms and peritonitis caused by non-enteric ***: Among the 120 patients who met the inclusion criteria, 61 patients had at least one episode ofperitonitis and 59 patients never experienced peritonitis. Twenty-four of 61 patients(39.3%) in group A and 15 of 59 patients(25.4%) in group B used gastric acid suppressants. Only the use of H2-blocker(H2B) was associated with an increased risk of PD-related peritonitis; the use of proton pump inhibitors, other antacids, and prokinetics was not found to be a significant risk factor for PD-related peritonitis. A total of 81 episodes of peritonitis were divided into enteric peritonitis(EP) or non-enteric peritonitis, depending on the causative organism, and gastric acid suppressants and prokinetics did not increase the risk of EP in PD ***: The use of H2B showed a trend for an increased risk of overall PD-related peritonitis, although further studies are required to clarify the effects of drugs on PD-related peritonitis.

Pprimary breast lymphoma （PBL） is rare, accounting for 0.04%-0.50% of breast malignancies and 1.7% of extranodal lymphoma The originally descnibect diagnostic criteria for PBL2 remains the standard definition for this disease. These criteria are breast location as the clinical site of presentation, absence of history of previous lymphoma or evidence of widespread disease at diagnosis, close association of lymphoma with breast tissue in pathologic specimens, and involvement of ipsilateral lymph nodes if they develop simultaneously with PBL.
