Kolloidale Verarbeitung und Sintern von nanoskaligem TiN-Pulver

Ein nanoskaliges TiN Pulver mit einer spezifischen Oberflache von 54m2/g wurde oberflachenmodifiziert, wobei die auf der Pulveroberflache lokalisierten Ti-OH Gruppen als Kopplungszentren dienten. Durch die dadurch etablierten abstosenden Wechselwirkungskrafte wurde dieses Pulver bis auf seine Primarteilchengrose von 40 nm redispergiert und daraus stabile, nanodisperse TiN-Suspensionen mit hohen Feststoffgehalten bis 40 Gew. - hergestellt. Sinterexperimente an den aus diesen Suspensionen uber Schlickerdruckgus hergestellten Formkorpern mit Grundichten um 52 ergaben, dass uber druckloses Sintern eine vollstandige Verdichtung bei Temperaturen bei 1400°C erfolgt und bis zu relativen Dichten von 95 nur ein geringfugiges Kornwachstum (mittlere Korngrose < 70nm) stattfindet. Der Zusammenhang zwischen der Harte und der Korngrose der verdichteten TiN-Proben mit mittleren Korngrosen unter 200 nm ist durch die Hall-Petch-Beziehung beschreibbar. Im weiteren wurde festgestellt, dass die stabile, nanodisperse TIN-Suspensionen auch fur die Herstellung von TiN-Grunschichten verschiedener Dicke uber Verfahren wie z.B. Tauchbeschichtung geeignet sind, die uber eine nachtragliche Sinterbehandlung bei Temperaturen um 1300°C verdichtet werden konnen. Als eine weitere Einsatzmoglichkeit dieser TiN-Suspensionen wurde die Herstellung von Kompositen erarbeitet, wo TiN als Verstarkungsphase in nanodisperser Form eingebracht werden mus. Nano scaled TiN with a specific surface area of 54 m2/g was surface modified by using of Ti-OH groups localized on the powder surface as coupling center for the organic modifier. Due to the repulsive forces introduced by this way, the powder were redispersed in aqueous medium down to the primary particle size of 40 nm. Further on, stable aqueous slurries of solid contents up to 40 wt. - with nanodispersed TiN which were used for the preparation of green bodies by pressure slip casting. Sintering experiments on the green samples with relative densities around 52 revealed that a full densification takes place by pressureless sintering at 1400°C in nitorgen atmosphere. It was observed that up to relative densities around 52 revealed that a full densification takes place by pressureless sintering at 1400°C in nitrogen atmosphere. It was observed that up to relative densities of 95 no significant grain growth occured (Average grain size < 70nm). At relative densities above 95 an accelerated grain growth takes place. The relation between the hardness and grain size obeyed to a Hall-Petch law in the grain wize area under 200 nm. Using TiN slurries were green TiN coatings of different thickness on different substrates were prepared by dip coating and subsequent densification at around 1300°C. another application field for the TiN slurries was the composite materials in which a homogeneous TiN distribution was archived by using colloidal methods and TiN slurries from surface modified starting powder.

Low Pressure Systems and Extreme Precipitation in Southeast and East Asian Monsoon Regions

Understanding the physical mechanisms behind the secular trends of summer rainfall extremes over the heavily populated Southeast and East Asian monsoon regions is not only of scientific importance but also of considerable socioeconomic implications. In this study, the relevance of the excessive-rain-producing low pressure systems (LPSs) to extreme rainfall is quantified. Using an objective feature-tracking algorithm, the synoptic-scale LPSs are identified and tracked in the 40-yr ECMWF interim reanalysis. The region experiences approximately 16 terrestrial and 18 marine LPSs each summer. The terrestrial LPSs form near the downwind side of the Tibetan Plateau and travel northeastward toward jet latitudes. The marine LPSs form over the western North Pacific Ocean and migrate along the western periphery of the subtropical high. While both types of LPSs account for a large portion of upper-tail rainfall, the terrestrial LPSs predominantly impact the extreme rainfall over inland areas, and the marine LPSs primarily affect the coastal regions where they frequently make landfall. The historical extreme rainfall trend during 1979–2018 aligns with the changes in LPS tracks. The decreasing number of northeastward-moving terrestrial LPSs leads to an extreme rainfall dipole with negative trends in north-central China and positive trends in southern China, while the increasing number of northward-recurving marine LPSs enhances the extreme rainfall in the eastern China coast but suppresses it over the South China Sea. These trends are driven dynamically by the weakening of the monsoonal southwesterlies and the eastward retreat of the subtropical high, which might be attributable to anthropogenic forcings.

Differences in mechanisms of salt tolerance between rice and barley plants

Abstract Mechanisms of salt tolerance were estimated in terms of the ATPase activity in roots, the Na excluding- ability of roots, and the regulation of Na translocation from roots to shoot by comparing Na tolerant plants (barley) and Na sensitive plants (rice) grown at high NaCl concentrations. The results obtained were as follows. 1. As the relative dry weight (dry weight at high NaCl concentration in the medium to the dry weight at 2 mM NaCl concentration in medium) of rice decreased remarkably with the increase of NaCl concentration in the medium compared to that of barley, salt tolerance of barley was higher than that of rice. High salt tolerance of barley was ascribed to the fact that Na translocation from roots to shoot was prevented at high NaCl concentration in the growth medium. 2. ATPase activity in roots of rice decreased remarkably with the increase of NaCl concentration (50 to 200 mM NaCl), while that of barley grown at a high NaCl concentration remained high. Since the effect of the NaCl co.

Event-triggered guaranteed cost control of time-varying delayed fuzzy systems with limited communication

Modern network applications place higher demands on its controller, especially for those with time-varying delays and limited communication capacity. For such cases, the fuzzy system has already become an advanced and powerful tool to deal with the control problem in consideration of a guaranteed cost performance. In this paper, we introduce the event-triggered mechanism with quantization effect to the controller, which proves to be more effective in terms of the information transmission. We adopt the classical Lyapunov approach to find the sufficient conditions for the controller and we illustrate the effectiveness of the controller with a numerical simulation.
PERBANDINGAN INTERPRETASI SKALA NYERI ANTARA NRS-VAS-WBFS OLEH PASIEN PASCA OPERASI ELEKTIF ORTHOPEDI DI RSUD Dr. SOETOMO

Health management is still a challenge in health services. An instrument that can cure pain is easy, easy, with accurate interpretation and can be used by every party involved in pain management. The purpose of this study was to analyze the Numeric Rating Scale (NRS), Visual Analogue Scale (VAS), and Wong Baker Faces Scale (WBFS), which can be interpreted well by postoperative care patients. The research method used was an observational analytic study with a cross-sectional study design that analyzed the scale application (NRS, VAS, WBFS) in patients after elective orthopedic surgery at RSUD Dr. Soetomo Surabaya. This study analyzed primary data of postoperative patients which contained socio-demographic characteristics, type of anesthesia given, pain scores and patient interpretation of pain scales through special instruments. The results showed that 102 research subjects were needed. The pain scale interpretation instrument was declared valid and reliable (Cronbach Alpha> 0.60). Mean pain scores from the VAS scale (4.29), NRS (4.82) and WBFS (4.81). No significant difference was obtained NRS scale and WBFS scale (Sig> 0.05). Mean interpretation of pain scale from the VAS scale (13.62), NRS (17.14) and WBFS (21.33). There was a significant difference in the pain score of the VAS scale against the NRS scale, also the WBFS scale (Sig <0.05). There were significant differences between pre and post operations, in clinical parameters of systolic blood pressure, diastolic blood pressure, pulse, and respiratory rate (Sig. <0.05). The conclusion from this study is that NRS, WBFS or VAS all work well in measuring pain. WBFS has the best scale interpretation value.
The Influence of Thematic Learning Implementation on Student Motivation in Public Elementary School 002 Sungai Pinang Samarinda

Thematic learning is learning with a theme to combine several lessons so that it can provide a meaningful experience to students. This study aims to analyze the effect of the implementation of thematic learning on the learning motivation of grade V students at SDN 002 Sungai Pinang Dalam Samarinda in the 2019/2020 learning year. This type of research is ex post facto research, because there is no control over the independent variables. This study consists of two variables, namely the independent variable and one dependent variable. The independent variable is the implementation of thematic learning (X). The dependent variable is student learning motivation (Y). The population of this study were class V students of the 2019/2020 learning year at SDN 002 Sungai Pinang Dalam. The instrument used was a questionnaire. The data analysis techniques were data normality test, homogeneity test, data linearity test and simple linear regression test. Researchers also do not make arrangements or manipulate the independent variables. The results showed that there was a significant influence between the implementation of thematic learning on the learning motivation of grade V students at SDN 002 Sungai Pinang Dalam Samarinda for the 2019/2020 learning year with a moderate determination coefficient value of 0.50 or 50%. From the regression equation Y = 14.774 + 0.759X, it can be seen that the consistency value of the thematic learning implementation variable is 14.774 while the X regression coefficient is 0.759 which states that every 1% of thematic learning (X) implementation will increase student learning motivation by 0.759. The regression coefficient is positive, thus it can be said that the direction of the influence of the thematic learning implementation variable on student learning motivation is positive.
Priority effects and ecological restoration

Priority effects refer to the order or timing of species arrival, including how species that arrive early at a site either positively or negatively affect establishment, growth, or reproduction of species that arrive later. Despite the clear implications of priority effects for ecological restoration, there have been no reviews of how and where priority effects have been studied and the extent to which findings can be applied to restoration. Here, we systematically review the literature on priority effects by (1) synthesizing information from papers that compared simultaneous and nonsimultaneous planting or sowing; (2) discussing the mechanisms through which priority effects operate, (3) considering how these mechanisms might be manipulated to achieve restoration goals; and (4) highlighting future research needed to improve the use of priority effects in restoration. In a term‐targeted search, we found 43 studies that experimentally manipulated the order of arrival of different species. Overall, these concluded that even small delays in arrival time, as opposed to simultaneous arrival of species, can promote differences in subsequent community composition as well as ecosystem functions. There were very few studies on the long‐term stability of these priority effects, and the majority were conducted in temperate grasslands. Our findings suggest that creating alternative vegetation states via priority treatments is a promising avenue for restoration. However, for the concept to be best operationalized for restoration, we need research in more ecosystems that are priorities for restoration, and treatments that are followed over extended time periods.

Pronunciation Teaching Issues: Answering Teachers’ Questions

This article reviews questions that non-native (NNEST) and native speaker (NEST) teachers, working in different contexts, have about pronunciation teaching. It draws on theory, research, and practice to answer those questions as far as possible. The data was collected across two projects that investigated teachers’ cognitions: their knowledge, beliefs, attitudes, and practices. The first project involved semi-structured interviews with 28 NNESTs in Uruguay while the second was set in New Zealand and involved questionnaires (N=83), semistructured interviews (N=19) and classroom observations (N=6). The 19 New Zealand interviews involved 11 with New Zealand English native (L1) speakers, six with Inner Circle variety of English L1 speakers, one Outer Circle bilingual, and one Expanding Circle bilingual speaker. While a number of results from these studies have already been reported (Couper, 2016a, 2016b, 2017, 2019), this article revisits the data in order to isolate questions and issues, and compare them across the two contexts. The data from Uruguay reveal insights into NNESTs’ perspectives while the data from New Zealand provide perspectives from those teaching Asian L1 students. Questions relate to: 1. the learner; 2. what to teach; 3. how to teach; 4. dealing with curriculum, textbook, and time issues; 5. teacher’s pronunciation ability and knowledge of phonetics and phonology There are some differences between the groups, such as NNESTs lacking confidence in their own pronunciation and NESTs lacking knowledge of phonetics and phonology. However, there are more similarities, with many questions not being specific to either context. These involve pedagogic knowledge and issues around priorities, setting goals, and space for pronunciation teaching. The questions and issues are addressed in terms of theories and what is known from the increasing body of research into pronunciation teaching. Practical examples of how this knowledge can be applied in the classroom are also suggested.
Product quality and quantity with responsive pricing

In this paper, we study a firm's optimal joint product quality and quantity decisions when the consumers' utilities change with the market environment. We develop a model framework to study a monopolist firm's decisions about product quality and related production quantity planning when responsive pricing is implemented. Consumers are heterogeneous in their marginal valuations of the product quality but homogeneous in their reservation utility. Considering a utility function incorporating the reservation utility, quality, and price, consumers make their purchase decisions. We find that as the reservation utility increases or the quality valuation decreases, the optimal quantity increases. However, counterintuitively, the optimal quality decreases when the reservation utility becomes higher. Furthermore, the product quality and quantity are substitutes in the context of responsive pricing. We also investigate the optimal quality and quantity for a product line that is vertically differentiated. Compared to a firm offering a single product, a firm offering a product line is more likely to alter its quality investment decisions due to changes in reservation utility, whereas the optimal investment decisions are less sensitive to changes in quality valuation.
Spectroscopic performance improvement of SOI pixel detector for X-ray astronomy by introducing Double-SOI structure

This paper reports the spectroscopic performance improvement of the silicon-on-insulator (SOI) pixel detector for X-ray astronomy, by introducing a double-SOI (D-SOI) structure. For applications in X-ray astronomical observatories, we have been developing a series of monolithic active pixel sensors, named as “XRPIXs,” based on SOI pixel technology. The D-SOI structure has an advantage that it can suppress a parasitic capacitance between the sensing node and the circuit layer, due to which the closed-loop gain cannot be increased in our conventional XRPIXs with a single-SOI (S-SOI) structure. Compared to the S-SOI XRPIX, the closed-loop gain is doubled in the D-SOI XRPIX. The readout noise is effectively lowered to 33% (16 e− (rms)), and the energy resolution at 6.4 keV is improved by a factor of 1.7 (290 eV in FWHM). The suppression of the parasitic capacitance is also quantitatively evaluated based on the results of capacitance extraction simulation from the layout. This evaluation provides design guidelines for further reduction of the readout noise.
Blockchain technology in healthcare: Challenges and opportunities

ABSTRACT Patients and healthcare practitioners are faced with the challenge of accessing, managing, integrating, and sharing health records securely. Patients should be able to manage their health records anywhere in the world, keep track of medical background, give access to data, and share those with any healthcare professional securely. Direct access to data for patients and a more robust data-sharing infrastructure could better prepare the healthcare system to manage public health threats during the emergence of deadly disease outbreak such as COVID-19. Current technologies in use by the healthcare industry do not adequately address these requirements due to limitations related to privacy, security, and full ecosystem interoperability. This paper conducted a literature review to find out the pivotal roles blockchain technology play in solving some of the most critical and challenging issues facing the healthcare industry. This paper identifies challenges and opportunities for implementing blockchain technology in healthcare and summarizes health-related blockchain products and key players offering solutions across different applications. In doing this, our research extends and complements existing blockchain research in healthcare.
Rank and File Employee Satisfaction and the Implied Cost of Equity Capital

Rank and file employees execute firms’ daily operating activities, but prior research rarely examines their importance due to a lack of employee information. In this article, we use a novel data set—company reviews by rank and file employees—to provide evidence on the impact of employee satisfaction on a firm’s cost of equity capital. We find that firms with higher employee satisfaction have a lower cost of equity. Our results are robust to a variety of endogeneity tests and model specifications. We also find that the effect of employee satisfaction is more pronounced for firms with higher risk, greater financial constraints, and higher labor intensity or product market competition where labor is more critical to firm success. Further analysis shows that the negative association between employee satisfaction and the cost of equity is primarily grounded in reviews from current rather than former employees. Finally, we document that firms with high employee satisfaction experience lower systematic and idiosyncratic risk. Overall, our article presents novel evidence on the capital market benefits of higher employee satisfaction, particularly with regard to financing cost reduction.
