Water entry of an expanding wedge/plate with flow detachment

A general similarity solution for water-entry problems of a wedge with its inner angle fixed and its sides in expansion is obtained with flow detachment, in which the speed of expansion is a free parameter. The known solutions for a wedge of a fixed length at the initial stage of water entry without flow detachment and at the final stage corresponding to Helmholtz flow are obtained as two special cases, at some finite and zero expansion speeds, respectively. An expanding horizontal plate impacting a flat free surface is considered as the special case of the general solution for a wedge inner angle equal to ${\rm\pi}$ . An initial impulse solution for a plate of a fixed length is obtained as the special case of the present formulation. The general solution is obtained in the form of integral equations using the integral hodograph method. The results are presented in terms of free-surface shapes, streamlines and pressure distributions.
Fine-scale analysis of arrowtooth flounder Atherestes stomias catch rates reveals spatial trends in abundance

Multiple lines of evidence suggest that changes in the marine climate in the eastern Bering Sea are leading to numerical and distributional shifts in fish populations that may affect the balance of predatorprey relationships. A rapidly increasing arrowtooth flounder Atheresthes sto- mias population has prompted concern about the growing threat of arrowtooth flounder predation on economically valuable walleye pollock Theragra chalcogramma. The goal of this study was to investigate the overall increasing trend of arrowtooth flounder at a finer spatial resolution to better understand the potential spatial variability in their predatory impact under a changing climate. The specific objectives were to determine whether arrowtooth flounder were increasing equally throughout the eastern Bering Sea and, if not, (1) identify areas with dissimilar abundance trends and (2) explore physical and biological habitat characteristics that may be contributing to these differences. Clustering arrowtooth survey catch per unit effort revealed 4 distinct spatial groups showing stable, increasing, and variable trends. Increasing bottom water temperature and depth were associated with higher proportions of trawls containing arrowtooth and higher catch rates. Age-1 and -2 pollock were the predominant prey in all areas, but higher rates of non-empty stom- achs in the northwest region indicated that current predatory impacts on pollock may be higher there. Favorable physical habitat (deep and warm) and diet trends (full stomachs) suggest that arrowtooth flounder in the northwest region of the eastern Bering Sea have the potential to increase further, perhaps to the abundance levels seen in the high-density area where they may have reached carrying capacity.
Evaluation of Deficit Irrigation and Mulching on Water Productivity of Tomato (Lycopersicon esculentum Mill) Under Drip Irrigation System at Kallu Woreda, South Wollo, Ethiopia

This study investigated the combined effects of deficit irrigation under drip irrigation system and mulches on yield and water-use efficiency on tomato production at Miawa Farmer Training center, south Wollo, and Kallu worda during 2016 irrigation season. A factorial combination of three levels of water (namely 70%, 80% and 90% ETc) combined with three mulch treatments (namely, without mulch (WM), sugarcane mulch (SM) and bulrush mulch (BM)) with three replications. The yield and yield-contributing all parameter in the mulched treatments for all levels of irrigation there is significantly difference compared to those in the un-mulched treatments. The yield of tomato increased with the increasing amount of irrigation water in un-mulched treatment. The trend was reversed when drip irrigation was coupled with mulches. The highest yield for each mulch (44.04 t/ha for sugarcane and 30.19 t/ha for bulrush) was obtained when 80% and 90% of water requirement was applied respectively. With 90% water application, sugarcane-mulched treatment produced lower yield than the bulrush-mulched treatment. The highest head volume and plant height recorded on 80% ETc with sugarcane mulch (54.67 cc and 84.33 cm, respectively). The highest water use efficiency was obtained 142.96 kg/ha/mm with 80% water application under sugarcane mulch. The study thus reveals that drip irrigation with mulch has an explicit role in increasing the yield and water productivity of tomato.
In vitro sterilization procedures for micropropagation of 'Oblačinska' sour cherry.

Surface sterilization is the most important step in preparation of explants for micropropagation, because controlling fungal and bacterial contamination of woody plant from field sources is very difficult. Six sterilizing agents: sodium hypochlorite (NaOCl), calcium hypochlorite [Ca(ClO)2], sodium dichloroisocyanurate (DICA), mercuric (II) chloride (HgCl2), silver nitrate (AgNO3) and hydrogen peroxide (H2O2) were tested for sterilization of ‘Oblacinska’ sour cherry buds, by varying their concentration and time of exposure. The aim of this study was to establish best surface sterilization for in vitro propagation of ‘Oblacinska’ sour cherry. Aseptic cultures of ‘Oblacinska’ sour cherry were established from axillary buds which were placed in nutrient medium, supplemented with plants hormones 6-benzylaminopurine (BA), 1- naphthaleneacetic acid (NAA) and gibberellic acid (GA3). The results indicated that among these sterilizing agents silver nitrate (AgNO3) at concentration of 1% for 20 minutes was the best for controlling the infection, whereas sterilization with sodium dichloroisocyanurate (DICA) at concentration of 1% for 10 minutes was not satisfactory.
EFFECT OF RISK AVOIDANCE STRATEGY ON THE SUCCESS OF CONSTRUCTION PROJECTS IN THE JUDICIARY AT NAROK COUNTY COURTS

Risk management is an idea which has become very popular among the researchers. Many firms are often instituting a risk management technique in their projects for refining the performance of the projects. One aspect of risk management is Risk Avoidance. Risk avoidance implies declining to acknowledge the hazard by any means. Projects undertaken in the construction sector are generally complex and often have significant budgets, and thus understanding of the strategies to an employee in reducing the risks associated with these projects should be of importance for the project managers. The general objective of this study was to assess the effect of risk avoidance strategy on the success of construction projects. The target population consisted of 60 employees drawn from Narok county courts, which comprises of Narok Law courts and Kilgoris Law Courts. Data were collected from 45 respondents drawn from employees who took part in the day to day running of the projects in these two courts. The descriptive survey research design was used in this study. Data collected was analyzed and interpreted. The qualitative data was analyzed in field and subfield as per objectives and quantitative data was analyzed using descriptive statistics namely mean, score, percentages and frequent distribution. Inferential statistics that is correlation and regression analysis was used to establish the effect of risk avoidance strategy on the success of construction projects in the Judiciary. The SPSS version 23.0 was used as the tool for data analysis. The results showed that majority of the respondents indicated that there was a weak correlation ( r = 0.118) between risk avoidance and project success which was not significant since the P- value was > 0.05. This showed that though risk avoidance might be an important risk mitigating strategy in project management but its effect on the success of the project is not significant. This implies that there might not be a statistical relation between risk avoidance and the success of a project. Keywords: Risk Avoidance, Construction projects, Success CITATION: Nturanu, J.

The Game of Love and Hazard: A Structural Model of Consumption and Saving

In the present paper, we consider a two-person household and study the risk that results from the stochastic fluctuations in the bargaining power of the household members. The model is inspired from the bargaining theory developed by Rubinstein and Binmore. We obtain the following results. i) The level of household investments in assets tends to increase in presence of this specific form of risk. ii) Spouses choose to invest funds in assets that have the largest negative effect on the variance of bargaining power. iii) Consumption inequality among spouses is lower in the richest couples.
Kobayashi–Hitchin correspondence for analytically stable bundles

We prove the existence of an Hermitian–Einstein metric on holomorphic vector bundles with an Hermitian metric satisfying the analytic stability condition, under some assumption for the underlying Kähler manifolds. We also study the curvature decay of the Hermitian–Einstein metrics. It is useful for the study of the classification of instantons and monopoles on the quotients of four-dimensional Euclidean space by some types of closed subgroups. We also explain examples of doubly periodic monopoles corresponding to some algebraic data.
Towards pluralistic and grassroots national identity: a study of national identity representation by the Kurdish diaspora on social media

ABSTRACT This study examines the distinctive roles that social media play for the diasporic Kurds in regard to the political and nationhood process. It attempts to understand how the notion of Kurdayeti [Kurdish nationalism] has been affected by the growth of Kurdish social media. It argues: although the Kurdish political activism has been accelerated by the rise of social media and the ethnic identity discussions have become much more visible, the idea of a unified imagined Kurdish nation has been affected by the existing socio-political fragmentations among the Kurds and transformed into a participatory and pluralistic imagined community.

Anthophyllite Asbestos: The Role of Fiber Width in Mesothelioma Induction Part 1: Epidemiological Studies of Finnish Anthophyllite Asbestos

Anthophyllite asbestos only occurs in a few parts of the world in sufficient quantities to be mined. The largest deposits of anthophyllite asbestos occur in Finland where it was mined for more than 75 years and very extensively used and distributed, anciently, for more than six millennia. Anthophyllite is one of the five minerals known collectively as amphibole asbestos. Studies of the effect of these five mineral fibre types when inhaled have shown that fibre width is an important determinant of mesothelioma induction. Only the “thinner” fibres or those with fiber diameter dimensional profiles predominantly less than 0.25 – 0.30 µm, are clearly mesotheliogenic. The “thicker” ones or those whose predominant widths are greater than these diameters do not appear to show an observable attendant risk of mesothelioma. Observations based on studies of at least, two “thick” forms of amphibole asbestos support these hypotheses. The one is Bolivian crocidolite; the other Finnish anthophyllite. The Finnish anthophyllite industry presents an important opportunity to study the robustness of the theory that fibre width is key to mesothelioma genesis as vast numbers of people in all sectors of the Finnish industry and their families have historically incurred massive fiber exposures sufficient to cause a gross excess of asbestosis. Nonetheless, in spite of these long term, high dose exposures clear evidence for a mesothelioma risk due to anthophyllite asbestos is still lacking.
Modeling and Simulation of CO2 Absorption Enhancement in Hollow-Fiber Membrane Contactors using CNT–Water-Based Nanofluids

Absorption of CO2 from a gas mixture containing CO2 and nitrogen by water-based CNT nanofluids in gas–liquid hollow fiber membrane contactor was modeled and solved using COMSOL Multiphysics 5.4. The model assumed partial wetting of the membrane, along with diffusion in the axial and radial directions. In addition, Brownian motion and grazing effects were both considered in the model. The main contribution to the mass transfer resistance for the case of external diffusion-controlled adsorption is the stagnant liquid layer around the particles, despite the layer being very thin. Accordingly, the nanofluid flows in the lumen tube side of the hollow fiber membrane was modeled as a solid-free zone and dense solid phase. The simulations were performed using 7% wetting of the membrane thickness. The results showed a significant increase in CO2 absorption with increasing concentration of carbon nanotubes (CNT). At a fixed inlet gas flow rate (20 L/h), increasing the CNT concentration from 0.1 wt. % to 0.25 wt. % increased the CO2 removal from around 20% to 45%. Comparison of the model predictions with experimental data available in the literature confirmed the validity of the developed model.
AN EXPERIMENTAL AND NUMERICAL STUDY OF SUPERCAVITATING FLOWS AROUND AXISYMMETRIC CAVITATORS

It has been shown that developing a supercavitating flow around under-water projectiles has a significant effect on their drag reduction. As such, it has been a subject of growing attention in the recent decades. In this paper, a numerical and experimental study of supercavitating flows around axisymmetric cavitators is presented. The experiments are conducted in a semi-open loop water tunnel. According to the Reynolds-Averaged Navier-Stokes equations and mass transfer model, a three-component cavitation model is proposed to simulate the cavitating flow. The corresponding governing equations are solved using the finite element method and the mixture Rayleigh-Plesset model. The main objective of this research is to study the effects of some important parameters of these flows such as the cavitation number, Reynolds number and conic angle of the cavitators on the drag coefficient as well as the dimensions of cavities developed around the submerged bodies. A comparison of the numerical and experimental results shows that the numerical method is able to predict accurately the shape parameters of the natural cavitation phenomena such as cavity length, cavity diameter and cavity shape. The results also indicate that the cavitation number declines from 0.32 to 0.25 leading to a 28 percent decrease in the drag coefficient for a 30 ◦ cone cavitator. By increasing the Reynolds number, the cavity length is extended up to 322% for a 60 ◦ cone cavitator.
Modernizing Without Westernizing: Social Structure and Economic Action in the Indian Financial Sector

To better understand whether the transition by Asian countries toward market economies mirrors the path taken in the West, we ask how embedded network ties between equity analysts and the chief executive officers (CEOs) of the firms that they follow in India influence the accuracy of analysts' earnings forecasts. We contrast traditional institutions of caste and regional language with contemporary institutions, such as universities, as the locus of such ties. We posit that CEOs from the postreform generation are more likely to transfer material private information via their school ties, while prereform-generation CEOs favor caste or language ties. Contrasting domestic business groups (BGs) with Western multinational corporations (MNCs) as organizational contexts, we argue that BGs legitimate the transfer of private information along particularistic ties, whereas MNCs mitigate such transfers. Our conceptual framework is supported by analyses that draw on a sample of 1,552 earnings forecasts issued between 2001 and 2010 by 296 equity analysts. Our findings suggest that the embeddedness perspective should be broadened to incorporate the influence of the larger historical social structures within which economic action is embedded, and to view BGs as carriers and repositories that blend modern management practices with particularistic behavioral patterns among top executives
Estimating the Equity Risk Premium for Economies in the Asian Region

The Equity Risk Premium (ERP) is widely used in economic and financial analysis, yet it is difficult to find empirical estimates of the ERP that are generally accepted. The paucity of data in Asian economies exacerbates the problems of estimation. This study estimates the ERP for the larger market-orientated Asian economies and compares the estimates with those of the United States. Surprisingly, of the seven economies examined, the ERP of four cannot be statistically differentiated from that of the United States.
E-learning in Tertiary Education

The vision common at the height of the dot.com boom of students following entire courses at a prestigious overseas university from the comfort of their own home, without the inconvenience and cost of living abroad for years has largely failed to materialise. Students are still mostly wedded to classrooms for at least part of the time, and after the hype of the new economy, growing disenchantment with e-learning has replaced earlier over-enthusiasm.

Damage Localization and Quantification of Truss Structure Based on Electromechanical Impedance Technique and Neural Network

Truss structure is widely used in civil engineering. However, it is difficult to quantitatively monitor the state of truss structures because of the connection diversity and complexity of truss structures. In this paper, electromechanical impedance (EMI) technique was proposed to measure impedance spectra by using PZT elements and backpropagation (BP) neural network was used as an effective nonlinear conversion tool to quantify the health state of truss structures. Firstly, frequency band of the spectrum was experimentally determined by the trial-and-error approach. Then four connection rods of this truss structure were selected for experimental research. These connection rods were loosened gradually with a small angle increment and the impedance spectra were recorded. Then, the measured data were compressed through dividing the frequency range into multiple subbands. And RMSD values of these bands showed that data points were reduced while damage features remained. Finally, one four-layered BP neural network model was constructed based on these compressed data. The research results showed that compressed impedance data could retain their damage features. After the training, the developed neural network model could not only determine the location of loosened rod, but also quantify the loosening levels.
Solar radiative transfer in Antarctic blue ice: spectral considerations, subsurface enhancement, and inclusions

Abstract. We describe and validate a Monte Carlo model to track photons over the full range of solar wavelengths as they travel into optically thick Antarctic blue ice. The model considers both reflection and transmission of radiation at the surface of blue ice, scattering by air bubbles within it and spectral absorption due to the ice. The ice surface is treated as planar whilst bubbles are considered as spherical scattering centres using the Henyey-Greenstein approximation. Using bubble radii and number concentrations that are representative of Antarctic blue ice, we calculate spectral albedos and spectrally-integrated downwelling and upwelling radiative fluxes as functions of depth and find that, relative to the incident irradiance, there is a marked subsurface enhancement in the downwelling flux and accordingly also in the mean irradiance. This is due to the interaction between the refractive air-ice interface and the scattering interior and is particularly notable at blue and UV wavelengths which correspond to the minimum of the absorption spectrum of ice. In contrast the absorption path length at IR wavelengths is short and consequently the attenuation is more complex than can be described by a simple Lambert-Beer style exponential decay law – instead we present a triple exponential fit to the net irradiance against depth. We find that there is a moderate dependence on the solar zenith angle and surface conditions such as altitude and cloud optical depth. For macroscopic absorbing inclusions we observe both geometry- and size-dependent self-shadowing that reduces the fractional irradiance incident on an inclusion's surface. Despite this, the inclusions act as local photon sinks and are subject to fluxes that are several times the magnitude of the single scattering contribution. Such enhancement may have consequences for the energy budget in regions of the cryosphere where particulates are present near the surface. These results also have particular relevance to measurements of the internal radiation field: account must be taken of both self-shadowing and the optical effect of introducing the detector.
MATHEMATICAL MODELING OF DRYING MAIZE GRAINS IN DIFFERENT TEMPERATURES

The need to maintain the quality of the corn kernels during drying becomes of great importance the knowledge of the phenomena that occur at this stage. The objective of this study was to model the drying of grains in different air temperature conditions used in dryers in the Brazilian cerrado region. Drying was carried out with three drying temperatures (80, 100 and 120 0 C) in an oven with forced air circulation and convection. To adjust the mathematical models to experimental data, there were non-linear regression analysis using software Statistica 7.0 ® . It was observed that the higher the temperature of the drying air (120 °C) the faster the product has reached the equilibrium moisture content. It was found that the model was Midilli to define the best corn drying curves at air temperatures of 80, 100 and 120 °C. The effective diffusivity obtained from the drying of corn was higher (5.4 x 10 -13 m 2 s -1 ) at a temperature of 120 °C. In conclusion, the drying of the grain at higher temperatures (above 100 °C), so has the power isosteric desorption (3885 kJ kg -1 ) to carry out the process.
