Research on the Flow Characteristics in the Gap of a Variable-Speed Pump-Turbine in Pump Mode

Field: Engineering (Physical Sciences)

A variable-speed pump-turbine is the core component of a hydraulic storage and energy generation station. When the pump-turbine operates at a constant speed, its response to the power grid frequency is poor. In order to improve the hydraulic efficiency of the pumped storage unit, variable-speed units are used. However, there has been no numerical study on the effect of the rotational flow characteristics within the gap of a variable-speed pump-turbine. This paper calculates the flow characteristics within the gap of a variable-speed pump-turbine under three typical pump modes (maximum head minimum flow condition, minimum head maximum flow condition, and maximum speed condition). The research results indicate that the rotational speed significantly affects the pressure distribution, velocity distribution, and turbulent kinetic energy distribution within the crown and band gaps. The higher the speed, the larger the area of the high-pressure region before the runner inlet compared to other operating conditions, and similarly, the low-pressure area after the runner outlet is also larger than in other operating conditions. The change in speed mainly affects the internal flow field of the crown gap, with the most noticeable changes occurring in the pressure and flow velocity at the inlet and outlet of the crown gap. There is a clear trend of pressure drop and velocity increase within the gap as the speed increases. However, with the increase in speed, the pressure distribution and flow velocity within the band gap remain almost the same. In addition to speed changes, it is observed that the pressure within the gap and the flow velocity within the passages are also related to the head, especially in the condition of maximum head, where this relationship becomes more noticeable.

Field: Engineering (Physical Sciences)

The characteristic of design, main configuration and combustion adjustment of 1913t/h supercritical boiler in XiangTan Power Plant is introduced. Its commissioning is different from the steam drum boiler. For example, blow pipe, start-up of system, safety valve adjusting and stabilize combustion of low-load. It also suggest that detailed operation process of load rejection test and RB test. Attention has been paid on the problem occurring during the commissioning, including main steam temperature higher than expected when start up, vibration of main feed water pipe, malfunction of the 361 valve, the control of cooling air flow on burner and incorrect display of air flow for the coal mill etc, specially on the wall temperature of water wall and the temperature of the separator. The final result of 168h commissioning indicated that the main operation parameters have met the design requirements and unit is under stable and safety operation.
Biosorption of metal ions using natural adsorbents

Field: Chemistry (Physical Sciences)

A batch adsorption system was applied to study the adsorption of Ag+ on native chitosan and cross-linked chitosan beads. The chitosan beads were cross-linked with epichlorohydrin (ECH), ethylene glycol diglycidyl ether (EGDE) and glutaraldehyde in order to enhance their chemical resistance and mechanical strength. The amide shielded cross-linking method was also used to further enhance the adsorption capacity. Measured amount of native and cross-linked chitosan beads were used to adsorb different concentration of silver solution ranging from 15ppm to 120ppm. The results obtained were fitted to the Langmuir and Freundlich adsorption models whereby Langmuir isotherm showed better compatibility to the equilibrium data. It was found that native chitosan beads has the highest adsorption rate compared to those cross-linked chitosan beads. Different cross-linking agents also results in different adsorption capacity for silver ions with the same amount of chitosan beads. The amide shielded cross-linking method also reflected a higher adsorption capacity for the chitosan beads than the rest which were done using direct cross-linking method. Titration tests were also carried out using 0.001 M NaOH to determine which cross-linking method is able to conserve the most amide functional group which is the main site for the adsorption of metal ions to the chitosan beads. The method of cross-linking chitosan beads to enhance its adsorption capability was successfully applied to the adsorption of silver ions in water. It was able to achieve a comparative results in which a conclusion can be made on which cross-linking method for chitosan would be the best for the adsorption of silver ions from water.
Role and metabolism of high density lipoprotein subfractions--analysis of serum HDL2-cholesterol and HDL3-cholesterol in patients with various diseases by high performance liquid chromatography.

Field: Medicine (Health Sciences)

In order to study the role and metabolism of high density lipoprotein (HDL) subfractions, the serum HDL2-cholesterol (HDL2-C) and HDL3-cholesterol (HDL3-C) were measured by the new method using high performance liquid chromatography in the normal subjects and patients with various diseases. It was highly characteristic that the serum HDL3-C levels of the patients with liver cirrhosis (LC) were remarkably lower than those of the normal subjects. The result suggests that HDL3 may be produced in the liver. Both the serum HDL2-C and HDL3-C levels were significantly lower in the patients with coronary heart disease (CHD) or cerebral thrombosis (CT) than in the normal subjects (P less than 0.001). In the normal subjects, the changes in the serum HDL-cholesterol (HDL-C) levels were mainly due to those in the serum HDL2-C levels. On the other hand, in the patients with atherosclerotic diseases (CHD, or CT) the changes in the serum HDL-C levels Were attributed to those of both the serum HDL2-C and HDL3-C levels. So it is suggested that in the atherosclerotic diseases, in which the HCL-C is usually lower, the HDL3-C also may play an important role in the regulation of the total HDL-C and its anti-atherogenetic effect.
1784-PUB: Empagliflozin (EMPA) Enhances Vascular Insulin Sensitivity and Lowers Plasma ICAM in Subjects with Type 2 Diabetes (T2D)

Field: Medicine (Health Sciences)

Background: The mechanism(s) by which sodium-glucose cotransporter 2 inhibitor (SGLT2i) use improves cardiovascular and renal outcomes in T2D are not well-defined. We hypothesized that EMPA would increase vascular insulin sensitivity and decrease endothelial cell (EC) stress markers in T2D. Study Design: Ten 18-60 years-old persons with T2D, 6.5 &lt; a1c 3 months, were studied. we measured vascular stiffness (pulse wave separation analysis), ec function (flow-mediated dilation (fmd)), and stress biomarkers (elisa) before after a 2-hour, 1 mu min kg euglycemic clamp at 0 12 weeks treatment with 10 mg empa daily. results: not wk 0, but wks, insulin decreased forward backward arterial pressures from 28±3 to 20±2 24±3 13±1 mmhg, respectively, (p&lt;0.02, each) improved the fmd response (p="0.02)," indicating function. peripheral systolic diastolic unchanged by week declined (p&lt;0.03, treatment. lowered baseline post-insulin plasma icam-1 (p&lt;0.002, increased vcam-1 (p&lt;0.0005). infusion pecam-1 (p&lt;0.03) vasoconstrictor endothelin-1 (p&lt;0.01) comparably or without e-selectin s100a8 9 did change significantly either empa. decrease suggests that inflammation. insulin’s action lower appeared independent of empa, may contribute empa’s beneficial actions. Interpretation: EMPA for 12 weeks enhanced insulin’s action to: 1) diminish arterial stiffness, 2) enhance EC function including biomarker release, and 3) lower blood pressure. Improved vascular insulin sensitivity may contribute to the improved CVD outcomes seen with SGLTi treatment. Disclosure T.Nguyen: None. L.Jahn: None. L.Hartline: None. K.W.Aylor: None.

"TREATMENT OF MIGRAINE WITH PEPTONE"

Field: Medicine (Health Sciences)

To the Editor:

—Perhaps you will kindly permit me to make a correction in the interesting paper of Drs. Miller and Raulston (The Journal, June 30), and also to add one or two remarks on the peptone immunization treatment. The preparation of peptone I have recommended is not Armour's peptonum siccum, as stated in the article, but Armour's peptone No. 2, which differs very considerably in that it contains a fair quantity of primary proteoses, a feature which is absent in the peptonum siccum. According to analyses made some years ago for me by Professor Plimmer, the peptone No. 2 contains one part of primary proteose to seven parts of deuteroproteose. This content of primary proteose renders the preparation more effective, and the larger size of the molecule would tend to induce a reaction much more readily, entailing greater care in the dosage. This particular peptone (No. 2) was that
Abstract B16: Verteporfin synergizes antitumoral effect of anti-PD-1 in mice cholangiocarcinoma models

Field: Medicine (Health Sciences)

Abstract Cholangiocarcinoma (CCA) is a heterogenous cancer originated from the biliary epithelium in the biliary tree system. The incidence of CCA has gradually increased across nation/worldwide and overall prognosis is poor with only 10% of 5-year survival rate. Recently developed immune checkpoint inhibitor-based immunotherapy has less benefit on CCA patients. We investigated antitumoral effect of verteporfin in combination of anti-PD-1 in YAP/Akt and Notch/Akt hydrodynamic injected mouse model. Our result showed reduced liver weight in verteporfin treated mice group compared to vehicle treated mice group, both in anti-PD-1 and isotype control groups. Single cell RNA sequence showed there is reduced expression of stemness related cells from data observed in verteporfin treated group. B cell, CD8+ T cell, TAM M1 populations were increased in verteporfin treatment group and similar pattern was observed in anti-PD1 treated verteporfin group. In conclusion, verteporfin reduced tumorigenesis in CCA via control of cancer stemness in CCA animal models with anti-PD-1 immunotherapy.

Influence of Nitrogen Management Regimes on Milling Recovery and Grain Quality of Aromatic Rice in Different Rice Production Systems

Field: Agricultural and Biological Sciences (Life Sciences)

To examine the effect of nitrogen (N) management regimes on rice quality in different rice production systems, a field experiment was conducted in 2017 and 2018. The experimental treatments comprised of two production systems (transplanted rice: TPR and dry direct-seeded rice: DDSR) and six N management treatments (0, 50, 100, and 150 kg N ha−1 as basal, and 100 and 150 kg N ha−1 in three splits which were regarded as N1, N2, N3, N4, N5, and N6, respectively). The results revealed that the rice quality attributes, i.e., broken rice recovery, abortive kernel, bursting, and curling were increased by 8%, 14%, 8%, and 14%, respectively, under DDSR than TPR. In the case of N management, split application of N reduced the chalky kernel (44%), abortive kernel (23%), opaque kernel (31%), bursting (24%), and curling (31%), while kernel protein contents, water absorption ratio, cooked grain length, and elongation ratio were increased by 41%, 88%, 25%, and 26%, respectively, as compared to the basal application of N. In short, DDSR cultivation reduced the appearance and cooking quality traits but white head rice recovery and nutritional quality were comparable to TPR. However, N application in splits either in DDSR or in TPR potentially improved the grain quality of rice compared with the basal application.
Experimental Arabic Linguistics

Field: Arts and Humanities (Social Sciences)

This volume is the first systematic attempt to survey current progress in the relatively new field of Experimental Arabic Linguistics. While experimental work on Arabic linguistics has appeared sporadically in several venues in the past, the chapters in this book provide a more coherent picture of the exciting directions which the field is pursuing. They provide insights into the complex nature of the Arabic language and how native speakers process it, using cutting-edge experimental methodologies in the fields of phonetics, psycholinguistics, and typical and atypical language development. This volume is of particular interest to scholars, researchers, and students at both the undergraduate and graduate level, in the fields of linguistics and language studies and can be a point of reference for scholars and researchers in the fields of theoretical and experimental Arabic linguistics.
XPS of chemically modified low‐density polyethylene surfaces: observations on curve‐fitting the C 1s spectrum

Field: Chemistry (Physical Sciences)

Abstract The curve‐fitting of the complex C 1s envelopes (obtained under high‐energy‐resolution XPS conditions) resulting from the surface chemical modification of low‐density polyethylene has been investigated. The main problem is modelling of the dominant, asymmetric component due to unmodified hydrocarbon. Two approaches have been compared, namely the use of a full (four‐component) vibrational progression or a single peak with a lineshape recently introduced by Gelius. As well as goodness of fit criteria, the agreement between the measured O 1s intensity and that predicted from the intensities of the high‐binding‐energy C 1s components (from oxygen‐containing functional groups) was used in the assessment. Under the relatively low‐level, but practically relevant, modification conditions studied, the two approaches are equally effective. However, they can give rise to significant differences in the relative intensities of high‐binding‐energy components. Broadening of the various components as a function of treatment also has been studied. Copyright © 2002 John Wiley & Sons, Ltd.
The effect of Ginkgo biloba extract (EGb 761) on gliotic reactions in the hippocampal formation after unilateral entorhinal cortex lesions

Field: Neuroscience (Life Sciences)

Purpose: Ginkgo biloba extract (EGb 761) has been shown to facilitate behavioral and neuro-morphological recovery from brain injury, but less is known about its effects on glia. Since gliosis may be an important component of the recovery process, we tested the hypothesis that EGb 761 alters the time course and development of microglial activation and astrocytosis after brain injury. Methods: Rats were treated with either saline or EGb 761 and killed at 2 hrs, 1, 3, 7, and 14 days following unilateral entorhinal cortex (EC) lesions. Microglia and their precursors were visualized with a silver impregnation method, and astrocytes with GFAP. Results: Blood-borne monocytes/macrophages were seen as early as 2 hrs after injury in all animals. The side contralateral to the injury showed minimal microglial activation and there were no significant effects of drug treatment. On the side ipsilateral to the lesion EGb 761 enhanced microglial activation at 3, 7, and 14 days in the molecular layer and the hilus of the dentate gyrus; the areas of most profound deaf-ferentation after EC injury. Regions of the corpus callosum also showed enhanced microglial activation over the same time course. Reactive astrocytes were stained with GFAP and were found to be more numerous than activated microglia, particularly in the ipsilateral corpus callo-sum. EGb 761 treatment enhanced astrocytosis at 3 days in the molecular layer, the hilus, and the corpus callosum on the ipsilateral side. Conclusions: Taken together our results show that EGb 761 enhances, accelerates and prolongs the activation of microglia and astrocytosis at the site of injury.

Meanwhile, Total Asset Turnover Ratio (TATO) has a significant effect on share prices. The F test results show that simultaneously CR, DER, TATO, ROA and ROE have a significant effect on share prices in energy sector mining companies listed on the Indonesia Stock Exchange 2019-2022.
3D Galactic dust extinction mapping with multiband photometry

Field: Physics and Astronomy (Physical Sciences)

We present a method to simultaneously infer the interstellar extinction\nparameters $A_0$ and $R_0$, stellar effective temperature $T_{\\rm eff}$, and\ndistance modulus $\\mu$ in a Bayesian framework. Using multi-band photometry\nfrom SDSS and UKIDSS, we train a forward model to emulate the colour-change due\nto physical properties of stars and the interstellar medium for temperatures\nfrom 4000 to 9000 K and extinctions from 0 to 5 mag. We introduce a\nHertzsprung-Russel diagram prior to account for physical constraints on the\ndistribution of stars in the temperature-absolute magnitude plane. This allows\nus to infer distances probabilistically. Influences of colour information,\npriors and model parameters are explored. Residual mean absolute errors (MAEs)\non a set of objects for extinction and temperature are 0.2 mag and 300 K,\nrespectively, for $R_0$ fixed to 3.1. For variable $R_0$, we obtain MAEs of\n0.37 mag, 412.9 K and 0.74 for $A_0$, $T_{\\rm eff}$ and $R_0$, respectively.\nDistance moduli are accurate to approximately 2 mag. Quantifying the precisions\nof individual parameter estimates with $68\\%$ confidence interval of the\nposterior distribution, we obtain 0.05 mag, 66 K, 2 mag and 0.07 for $A_0$,\n$T_{\\rm eff}$, $\\mu$ and $R_0$, respectively, although we find that these\nunderestimate the accuracy of the model. We produce two-dimensional maps in\nextinction and $R_0$ that are compared to previous work. Furthermore we\nincorporate the inferred distance information to compute fully probabilistic\ndistance profiles for individual lines of sight. The individual stellar AP\nestimates, combined with inferred 3D information will make possible many\nGalactic science and modelling applications. Adapting our method to work with\nother surveys, such as Pan-STARRS and Gaia, will allow us to probe other\nregions of the Galaxy.\n
Alienated Body Images In Margaret Atwood's Selected Novels

Field: Arts and Humanities (Social Sciences)

I chose The Edible Woman, The Handmaid’s Tale and The Testaments as these novels represent how different power structures like capitalism and extreme fundamentalist, religious society both assert the inferiority of women and entitles themselves to exploit the female body. Although these power structures are based on different ideologies, the outcome is the same: alienation and objectification of the female body. In case of capitalism the female body becomes a purchasable commodity while in an extremely religious, authoritarian society a means of delivering babies, a reproductive organ. The novels clearly show that the main gender related issues root in the deep patriarchal stance of the humankind and political affiliation.
Multi-view Bi-clustering to Identify Smartphone Sensing Features Indicative of Depression

Field: Computer Science (Physical Sciences)

Depression is a major public health issue with direct and significant effects on both physical and mental health. In this study, we analyze smartphone sensing data to find differential behavioral features that are correlated with depression measures such as patient health questionnaire (PHQ-9). Our approach uses an innovative multi-view bi-clustering algorithm. It takes multiple views of sensing data as input to identify homogeneous behavioral groups and simultaneously the key sensing features that characterize the different groups. Using a publicly available dataset, we discover that these behavioral groups with differential sensing features are highly discriminative of PHQ-9 scores that are self reported by the study subjects. For instance, the group comprising less active users in the sensed activities corresponds to overall higher PHQ-9 scores. We then employ the key sensing features that distinguish the different groups to create predictive models to predict the group assignment of individuals. We verify the generalizability of these models using the support vector machine classifier. Cross validation studies show that our classifiers can classify individuals into the correct subgroups with an overall accuracy of 87%.
