Evaluation of determinants of acute kidney injury and mortality among patients attending intensive care unit: A retrospective study

Introduction: Acute Kidney Injury (AKI) in intensive care unit (ICU) portends worse outcomes and attendant with high mortality. Early identification of high risk patients can improve their outcomes and may reduce ICU mortality rate. Methodology: A retrospective data review of patient attending ICU during 1 year was performed. All the patients were divided into two groups based upon their outcomes (AKI/non-AKI, fatal/non-fatal cases). Risk factors of AKI and mortality were identified by using regression analysis. Results: A total 906 patients (mean age: 53.6 ± 15.3, male: 58.2%) were included into the study. The mean length of ICU stay was 14.4 ± 3.3 days. AKI was observed in 487 (53.8%) patients with varying severity including AKIN-I in 89/487 (18.3%), AKIN-II in 137/487 (28.2%) and AKIN-III in 261/487 (53.5%) cases. Old age (OR 2.8) diabetic patients (OR 1.9) with high SOFA (OR 2.7) and APACHE-II scores (OR 3.1) requiring IMV on admission (OR 4.2) were found to be significantly associated with AKI. Overall mortality in our study was 29.5%. Pulmonary (OR 1.7) and neurological (OR 3.3) causes of ICU admission, AKI (OR 6.2), AKIN-III (OR 3.2), high SOFA (OR 1.6) and APACHE II scores (OR 2.3), need of IMV (OR 7.2) and dialysis (OR 4.6) were significant predictors of mortality in our study. Conclusion: AKI was found among half of the patients attending ICU and significantly associated with in hospital mortality. Early identification of high risk patients can be useful to reduce the burden of AKI and mortality in ICU.
PRICE REACTION TOWARDS THE PENSION ACCOUNTING DISCLOSURES OF ACTUARIAL GAINS AND LOSSES

This paper investigates whether stock prices react to the pension accounting disclosures of actuarial gains and losses among defined benefit pension (DB) schemes adopters in Malaysia. Standard event methodology is adopted to examine the immediate price reaction of companies that disclosed the actuarial gains and losses for the year 2009. Using market adjusted return (MAR) Model, the results suggest that market is indifferent on the disclosures of actuarial gains or losses (i.e. either aggregate or segregate between companies that disclosed actuarial gains and losses) on disclosure date. An additional analysis further provides evidence that average abnormal returns (AAR) for companies that disclosed actuarial gains (i.e. average of 1.09%) are positive and significant after the disclosure date, while the markets have negatively reacted towards the disclosures of actuarial losses before the disclosure date (i.e. day -3, -8, -10). These findings suggest that the disclosures actuarial gains are more welcomed by investors and signal “good news” after the announcement date of annual reports.
SIMILARITY BASED AUTOMATIC ITEM CLUSTERING FOR EFFICIENT CLASSIFICATION OF INFORMATION SPACE

Clustering is a useful technique that organizes a large quantity of unordered objects into a small number of meaningful and coherent clusters. The goal of the clustering is to assist in the location of information. It is an essential data analysis method used in many applications such as psychology, biology, information retrieval and mining technologies. Nowadays all manual documents are in automated form, because of fast access and lesser storage. So, to retrieve appropriate documents from huge database it is a major issue. Clustering documents to related groups is one of the active field of research in different fields of text mining, topic tracking systems, and question answering systems. We are proposing four eminent clustering algorithms that use standard similarity metrics on a document corpus to perform the clustering. Here, presents a survey on these existing document clustering algorithms and proposes a framework for comparing them using a similarity measure with respect to a number of documents and processing time.
Regulation of methane gas output from an anaerobic reactor system using moving horizon H 1 control

In this study, the moving horizon H 1 control used for tracking a desired methane gas output from an anaerobic wastewater treatment reactor is compared with classical H 1 control and a proportional-int controller. The nonlinear system isrst linearized around the set of equilibrium and operating points selected, and then the linear matrix inequalities required to comply with the constraints and guarantee the stability are constructed. Finally, the experimental results are obtained by implementing the control method in a MATLAB environment. It is concluded that moving horizon H 1 control yields satisfactory results.
Hand gesture recognition using average background and logical heuristic equations

This paper introduces a hand gesture recognition algorithm for Human Computer Interaction using real-time video streaming . The background subtraction technique is used to extract the ROI (Region Of Interest) of the hand. Fingertip is detected using logical heuristics equations that are applied on hand contour , convex hull and convexity defects points. A combination between background subtraction and logical heuristic technique that leads to more accurate results is introduced. Experimental results prove that the proposed algorithm improve the finger's tips detection by 52 % compared to the reference model.
Buyer-seller conflict and cooperation in marketing channels: port wine distribution

The main purpose of this study is to research buyer-seller conflict and cooperation in distribution channels. Based on a multidimensional case study, eight research hypotheses were formulated. Some quantitative research was conducted, based on a questionnaire sent to 101 port wine producers and distribution companies (61 answered properly – 31 producers and 29 distributors – which gave the authors a 60% rate of response, considered to be very good for these types of studies; those 101 port wine producers and distributors initially chosen were the most important in Europe, considering the volume of production and sales, and constituting, for that reason, a convenience sample). A binary probit model was developed to analyze the data. The results of the study demonstrate that when conflict is ongoing and intense it prevents the development of cooperative relationships. A trustworthy company is more likely to solve conflicts. When trust and adaptation capabilities increase, so does potential cooperation. The results also show that the presence of a foreign sales representative in the team does not exert a negative influence on cooperation. Finally, cooperation can be considered as an important means of developing skills and resources, which can then be applied to existing transaction relationships.
The Milli-ArcSecond Structure Imager , MASSIM : A new concept for a high angular resolution X-ray telescope

MASSIM, the Milli-Arc-Second Structure Imager, is a mission that has been proposed for study within the context of NASA’s Astrophysics Strategic Mission Concept Studies program. It uses a set of achromatic diffractiverefractive Fresnel lenses on an optics spacecraft to focus 5-11 keV X-rays onto detectors on a second spacecraft flying in formation 1000 km away. It will have a point-source sensitivity comparable with that of the current generation of major X-ray observatories (Chandra, XMM-Newton) but an angular resolution some three orders of magnitude better. MASSIM is optimized for the study of jets and other phenomena that occur in the immediate vicinity of black holes and neutron stars. It can also be used for studying other astrophysical phenomena on the milli-arc-second scale, such as those involving proto-stars, the surfaces and surroundings of nearby active stars and interacting winds. We describe the MASSIM mission concept, scientific objectives and the trade-offs within the X-ray optics design. The anticipated performance of the mission and possible future developments using the diffractiverefractive optics approach to imaging at X-ray and gamma-ray energies are discussed.
Ambiguity , Liquidity , and Price E ¢ ciency

We develop a sequential trading model with ambiguity-averse market makers. Bid-ask spread contains a risk premium and an ambiguity premium. Higher ambiguity generally leads to higher market illiquidity, but there exist some thresholds at which liquidity suddenly dries up or oods, and the likelihood of occurrence depends on the salience of ambiguity relative to risk. Ambiguity impedes speed of learning and can generate jump clustering. Ambiguity skewness predicts future returns, hinders revelation of tail riskand can produce price over-reaction. Our model explains the market freezes and the Flash Crash, reconciles some conicting empirical results, and provides new testable predictions. Keywords: Ambiguity, Skewness, Market Liquidity, Return Predictability, Price E¢ ciency JEL Classi cation: D81, G12, G14. We thank Ming Guo and Yulei Luo for valuable discussion.

Family Satisfaction towards Care Provided to Criticaly Ill Patients and Associated Factors in the ICU of Governmental Hospitals of Addis Ababa Town, 2017

Intensive care unit is a special department of hospitals which is responsible to care for seriously ill patients. Patients in the ICU needs constant close monitoring from specialist and nurses with supportive equipments and medication [1]. The reason for admission world wide is different, the most common reason in Africa is head injury followed by respiratory failure, sepsis and obstetric couses [2-4]. ICU mortality rate in developed countries accounts 8% to 20%. Amoung all deaths, the ICU mortality rate accounts 20% in US, between 30% to 50% in africa. From east african countries a study in Uganda indicates 25% to 68% of death from medical and surgical ICU and 37.7% death in one referral hospital in Ethiopia [5-7].
Insights to slip behavior on rough faults using discrete element modeling

We simulate a range of fault slip behaviors using the discrete element method (DEM) to examine the controls on different slip modes on rough faults. Shear strain is imposed upon a 2‐D bonded particle assemblage that contains a predefined fault. Slip modes on the fault vary from creep, to slow‐slip, to stick‐slip behavior, both spatially and temporally. The mode of slip is controlled largely by the local stress field along the fault, which depends on the local fault roughness. Portions of the fault that fail in relatively low normal stress regimes tend to slide continuously, whereas areas with high clamping stress produce stick‐slip events. During stick‐slip events, regions within the rupture zone that experience high slip are associated with physical asperities on the fault; ruptures terminate at barriers and through dissipation of the stored elastic energy. The simulated events show stress drops between 0.2–50 MPa, a slightly larger range than is inferred for natural earthquakes. Simulated events also have higher slip magnitudes than are observed during earthquakes for a given rupture length. The simulation produces many characteristics of fault behavior and is shown to be a successful avenue for future studies on the mechanics of fault slip.
The Planetary Nebula Spectrograph survey of S0 galaxy kinematics - Data and overview

Context. The origins of S0 galaxies remain obscure, with various mechanisms proposed for their formation, likely depending on environment. These mechanisms would imprint different signatures in the galaxies' stellar kinematics out to large radii, offering a method for distinguishing between them. Aims: We aim to study a sample of six S0 galaxies from a range of environments, and use planetary nebulae (PNe) as tracers of their stellar populations out to very large radii, to determine their kinematics in order to understand their origins. Methods: Using a special-purpose instrument, the Planetary Nebula Spectrograph, we observe and extract PNe catalogues for these six systems. Results: We show that the PNe have the same spatial distribution as the starlight, that the numbers of them are consistent with what would be expected in a comparable old stellar population in elliptical galaxies, and that their kinematics join smoothly onto those derived at smaller radii from conventional spectroscopy. Conclusions: The high-quality kinematic observations presented here form an excellent set for studying the detailed kinematics of S0 galaxies, in order to unravel their formation histories. We find that PNe are good tracers of stellar kinematics in these systems. We show that the recovered kinematics are largely dominated by rotational motion, although with significant random velocities in most cases.

Vegetational responses of a mixed-grass prairie site following exclusion of prairie dogs and bison.

Combined grazing by black-tailed prairie dogs (Cynomys ludovicianus) and bison (Bison) produces and maintains a series of changes in the vegetation of prairie dog colonies. However, because their grazing patterns differ in frequency and intensity through time, their individual impacts may be different. The objective of this study was to determine the individual and combined influences of these 2 herbivores in maintaining selected vegetation characteristics of a prairie dog colony in a mixed-grass prairie at Wind Cave National Park, S.D. This was assessed by monitoring plant responses during 2 years following exclusion from grazing by 1 or both species. In spite of their different grazing patterns, prairie dogs and bison had similar and independent (i.e., additive) effects in maintaining plant community structure. For example, total above-ground biomass increased 32-36% within 2 years of removal of each species, primarily as a result of increases in accumulation of graminoid biomass. Plant species diversity, equitability, and dominance concentration were similar in all treatments both years, although there were slight decreases in relative abundance of forbs and increases in relative abundance of grominoids in the second year after removal of grazers. Mean graminoid leaf nitrogen concentration (May to September) declined slightly but significantly after removal of prairie dogs (1.49 to 1.38%) in 1985, and after bison exclusion (1.64 to 1.50%) in 1986. We suggest that rate of vegetation change following removal of grazers depends upon weather conditions, plant species composition, and prior intensity and duration of grazing.
Linear and Angular Modulator Using I/Q Mod Topology

Author(s) Title Number of Pages Date Subash Puri Linear and Angular Modulator Using I/Q Mod Topology 29 pages + 10 appendices 9 May 2016 Degree Bachelor’s degree Degree Programme Electronics Specialisation option Instructor(s) Thierry Baills, Senior Lecturer The thesis project was conducted to design and implement I/Q modulator and understand the flexibility of I/Q modulator to perform various kind of modulation with ease. It was also a prime focus of this thesis to identify effect of noise in carrier on the modulated signal and other possible sources of error. Total of four stages, 90° phase shifter, mixers, gain and summing stages, were designed and their circuit board were constructed. All the components except LT5560 were available in the University laboratory. The modulator simulation was also performed on Multisim software and the results were studied. After spectrum analysis of LT5560 at lower frequencies below 1 MHz, it was found that mixed signals gets highly attenuated and works pretty well above 5 MHz LO frequencies, but with leakage of LO frequency on output, hence the hardware implementation remained incomplete. Further analysis and fault finding can be done to make the system working and smaller in size.
Effect of ion cyclotron motion on the structure of wakes: A Vlasov simulation

The global structure of wake fields behind an unmagnetized object in the solar wind is studied by means of a 2.5-dimensional full electromagnetic Vlasov simulation. The interaction of a plasma flow with an unmagnetized object is quite different from that with a magnetized object such as the Earth. Due to the absence of the global magnetic field, the unmagnetized object absorbs plasma particles which reach the surface, generating a plasma cavity called a wake on the anti-solar side of the object. The interaction between the solar wind with an out-of-plane interplanetary magnetic field and an unmagnetized object of ion-gyro scale is examined to study the effect of the ion cyclotron motion on the structure of wake fields. It is shown that the wake boundary layer is broadened when the inner product of the electric force and the density gradient of the wake boundary layer is negative. On the other hand, a steep wake boundary layer is formed with a negative inner product. The result suggests that the structures of wake fields become asymmetric due to the in-plane E cross B drift motion of ions.
High-Resolution Spectroscopy of Some Very Active Southern Stars

We have obtained high-resolution echelle spectra of 18 solar-type stars that an earlier survey showed to have very high levels of Ca II H and K emission. Most of these stars belong to close binary systems, but five remain as probable single stars or well-separated binaries that are younger than the Pleiades on the basis of their lithium abundances and Hα emission. Three of these probable single stars also lie more than 1 mag above the main sequence in a color-magnitude diagram, and appear to have ages of 10 to 15 Myr. Two of them, HD 202917 and HD 222259, also appear to have a kinematic association with the pre–main-sequence multiple system HD 98800.
Emotion regulation requirements and affective forecasts regarding expected organizational changes

In organizational change processes, employees develop expectations of future events and make affective forecasts about their affective reactions to these events. When making such affective forecasts, people often project their current affect onto future events without considering the unique characteristics of the events. Although affective forecasts have been assessed in several applied settings, only a few studies have examined work contexts. Therefore, the objective of this study was to assess whether employees making work-related affective forecasts also rely on current affect. Moreover, the study investigated whether employees whose work frequently requires regulation of their emotions are less likely to project their current work-related affect into the future. Cross-sectional data gathered from 1610 Austrian eldercare workers supported these assumptions. Employees relied heavily on current affect when making work-related affective forecasts. However, employees who reported that their work demanded high levels of emotion regulation exhibited a weaker relationship between current affect and predicted affect. We suggest that these findings have implications for understanding and managing organizational change processes.

Evaluation of Urban Forestry and Housing Patterns in Awka Metropolis of Anambra State, Nigeria

This study evaluated urban forestry and housing patterns in Awka metropolis of Anambra State in Nigeria, with the aim of establishing the trend of housing and urban forestry / urban greening in the study area over a period of ten years (2001-2010) and to suggest ways of improving urban agriculture for a better environmental quality in Awka and other cities with high rate of developmental projects / urbanization. In other to establish this trend, the linear regression and correlation coefficient of the land use data over the time period was calculated using the concept of housing and urban forestry as a benchmark. The data analyses confirmed that there is a significant correlation between housing pattern (urbanization) and the vegetal distribution of trees (forestry) in Awka. Also, housing and urban forestry in Awka metropolis is spatially distributed in space; as shown in the results from the satellite imageries. The result of the least square regression showed that the rate of forest displacement is as a result of the increasing structural development in the study area. The work thus concluded by recommending the adoption of some tree planting techniques among urban structures and the replacement of failed trees by new one to be undertaken by the government, urban planners, land developers, the community and every individual.
