Sloshing and Scaling: Results from the Sloshel Project

At the turn of 2007 full scale wave impact tests have been carried out by MARIN in the frame of the Sloshel project. Unidirectional breaking waves were generated in a flume in order to impact an instrumented transverse wall with embedded test structures. The main goals of these tests were to study the hydro-elastic effects associated with the NO96 membrane containment system for LNG carriers and to create a sound database for validation of numerical simulations. The preliminary results were overviewed in 2009 by Brosset et al. Since then the full scale tests have been repeated at scale 1 to 6 in order to study the scaling effects. These tests are referred to as the large scale tests. The large scale test set-up mimicked as far as possible the full scale setup. At both scales the instrumentation consisted of multiple pressure sensors, accelerometers and load cells. Special attention was paid to observe the shapes of the breaking waves while impacting. This was obtained by optical sensors at full scale and high speed cameras at large scale, both synchronized with the data acquisition systems. These recordings provided insight in the sloshing physics and enabled to determine characteristic quantities like the amount of entrapped air for air pocket impacts and the corresponding oscillation frequencies. In order to compare deterministically measured impact pressures at both scales a similarity must be ensured on the global flow from the wave paddle to the instant just before the first contact with the wall. Such a similarity has not been achieved. Reasons for that are analysed and recommendations for further tests at full scale are given. Nevertheless a comparison is proposed restrained to global parameters describing gas pocket impacts like pressure within the gas pocket, frequency of the oscillations when compressed and damping coefficient of these oscillations. The similarity at both scales is based on the surface of the gas pocket when closing. So-called compressibility bias demonstrated theoretically and illustrated numerically by Braeunig et al., (2009) is confirmed experimentally. The 1D simplified model of Bagnold (1939) is presented to explain the process.
About boudins and mullions in the Ardenne-Eifel area (Belgium, Germany)

The terms 'boudin' and 'boudinage' have been coined in 1908 at Bastogne to describe the geometry of particular structures in Lower Devonian metasedimentary series, resembling an array of sausages lying side by side. Recent research shows that these structures are the expression of a polyphase deformation history in brittle-ductile deformation conditions in the middle crust. Hydraulic fracturing caused the formation of the vein arrays, while layer- parallel shortening is responsible for the cuspate-lobate morphology of both the lower and upper interface of the psammite layers. Taking into account the currently acknowledged geological nomenclature, particularly with respect to the terms boudin and mullion, the resulting structures should be described as mullions, or more particularly as double-sided mullions. Notwithstanding the fact that the kinematics giving rise to the particular structures in the Ardenne-Eifel area are not related to the process of boudinage, the Belgian geological community should strive for the creation of a heritage site at Bastogne, still the locality where the terms 'boudin' and 'boudinage' have been used for the first time.
Chasing psycholinguistic effects: A cautionary tale

Many studies have addressed the issue of whether age of acquisition and/or frequency affect particular lexical tasks. Methods typically employed in such studies are based on the general linear model (e.g., ANOVA or multiple regression). These methods assume manipulated independent variables whereas the usual approach of investigating age-of-acquisition and frequency effects uses estimated norms of word properties. This failure to truly manipulate variables violate the assumptions of the analyses. A simulation is provided that demonstrates how this violation can lead to erroneous conclusions of effects when none are present. Recommendations are made for a more correlational approach to analysis using structural equation modelling techniques. It is also discussed how this use of estimates of lexical data is problematic for determining effects throughout psycholinguistic research.
Stochastic prediction of wire coupling interference

Many EMC analyses of complex systems frequently result in a statement that insufficient knowledge is available to describe accurately the internal relationships of the system's components. This lack of information precludes any rigorous deterministic prediction and, in principle, requires that we express the uncertainties within the model. This paper shows the practical feasibility of stochastic prediction, as an alternative to deterministic simulation, applied to a class of EMC problems intrinsically affected by randomness. The evaluation of the crosstalk in standard cable bundles, in which several wires are tightly and randomly wrapped together, is the concrete problem that we investigate in this context. We developed a technique based on solving the nonuniform multiconductor transmission lines (MTL) for many randomly generated wires' geometries to obtain many crosstalk samples for a single frequency. Finally we validated the method, setting up a case study with published experimental results.
Influence of selected Polish and American rootstocks on the growth and yield of ‘Golden Delicious Reinders’ apple trees

Bielicki P., Pąśko M. (2018): Influence of selected Polish and American rootstocks on the growth and yield of ‘Golden Delicious Reinders’ apple trees. Hort. Sci. (Prague), 45: 18–21. This study was conducted in the period 2010–2015 to assess the influence of rootstocks on the growth and fruiting of apple trees of the ‘Golden Delicious Reinders’ cultivar. The experiment was conducted in an experimental orchard in Dąbrowice, Poland. The experimental material consisted of the Polish rootstocks P 66, P 67, P 68 and P 16, and the following American rootstocks of the Cornell Geneva series resistant to fire blight: CG.11, CG.41, CG.013 and CG.202. The rootstocks M.9T337, M.26, P 14 and P 60 were used as the control combination. The best-yielding trees were those from the CG.11 rootstock, while those from P 14 and P 67 were the lowest-yielding. Trees from the latter rootstocks grew most vigorously and had the lowest productivity index.
Using Innovation Surveys for Econometric Analysis

After presenting the history, the evolution and the content of innovation surveys, we discuss the characteristics of the data they contain and the challenge they pose to the analyst and the econometrician. We document the two uses that have been made of these data: the construction of scoreboards for monitoring innovation and the scholarly analysis of various issue related to innovation. In particular we review the questions examined and the results obtained regarding the determinants, the effects, the complementarities, and the dynamics of innovation. We conclude by suggesting ways to improve the data collection and their econometric analysis.
Tawhidic paradigm and organizational policy and strategy practices

This study explores the practice of Tawhidic Paradigm in organizational policy and strategy of small and medium enterprises (SMEs) in Malaysia. Tawhidic paradigm (TP) is an understanding to perform deeds in line with faith (‘aqīdāh), worship (‘ibādāh), and ethics (akhlāq) in the life as servant and vicegerent of Allah. In everyday life, one has to earn good value, which is compounded into the value of life as servant and vicegerent of Allah, enhances value in life, bottom line in the worldly and the Hereafter. TP is a guideline that based on Shari’ah, Islamic ethics and teaching principles for managing companies in the contemporary age. The TP is an addition to the existing standards and guidelines that produced by various agencies in Malaysia. The rigorous, comprehensive, and complete nature of TP contributes to beyond triple bottom line concerns of today’s companies for the sake of sustainability. This study uses personal interview with entrepreneurs of selected enterprises of SMEs in Malaysia. The entrepreneurs argued that they practiced TP according to teachings of Islam in terms of sincere, honest, truthful, and always abide by the teachings of Islam. Yet, they are still facing severe challenges to sustain their enterprises. However, they have strong dependency in Allah, and always reminding themselves to work hard as it is part of worshipping Allah. TP in OPS could bring significant practical implications in strategic management in enhancing efficiency, effectiveness, and sustainability of the companies. In conclusion, while the aware of TP in OPS significant theoretically, but in practice it has to be proven due to no such practices.
Assessment of heavy metal in self-caught saltwater fish from Port Dickson coastal water, Malaysia

Freshwater fish has been studied and reported numerously. However, little attention has been made and limited studies available on local marine fish in Malaysia. Thus, in this study, concentrations of heavy metals (Cd, Cr, Pb and Cu) were studied in four major local marine fish Megalaspis cordyla (hardtail scad), Rastrelliger kanagurta (Indian mackerel), Selaroides leptolepis (yellowstripe scad) and Sardinella fimbriata (fringescale sardinella). The study was also intended to estimate potential health risk assessment from these heavy metals to the consumption of fish and assess maximum allowable fish consumption rate. The range of heavy metal concentrations were 0.053-0.096 mg/kg for Cd, 1.16-2.34 mg/kg for Cr, 8.34-12.44 mg/kg for Pb and 1.40-3.21 mg/kg for Cu in four major self-caught saltwater fish. Heavy metal levels of Cd and Cu in the local marine fish from Port Dickson are below the limit enforced by Food Regulations (1985) while the levels of Cr and Pb have exceeded the limit. Potential health risks associated with Cd, Cr, Cu and Pb were assessed based on target hazard quotients. HQ values calculated for Cd, Cr and Cu were less than 1, thus indicate that no adverse effects while HQ values for Pb exceeded 1 for all the fish species assessed with the exception of Megalaspis spp. and Sardinella spp. Cr was the highest while Pb concentrations were the lowest in all the studied fish samples for maximum allowable fish consumption rate. A long term monitoring program is crucial to be done in coastal areas with high consumption of local marine fish along Port Dickson to obtain real consumption rates and other cofounders factors in local population.
Assessment of Radon Concentrations in the Soil of South Baghdad Suburbs

Measurements of radon gas concentrations were carried out for 12 soil samples at 3 sampling depths (surface, 5 cm and 10 cm) collected from (4) locations in south Baghdad suburbs (Bu'aitha) using solid state nuclear track detector CR-39 and sealed can technique. Radon concentrations for surface samples were ranged from 402.2 to 1538.4 Bq.m-3 with an average 994.4 Bq.m-3. Whereas, radon concentration was ranged from 813.1to 2050.4 Bq.m-3 and from 1309.8 to 4626. 1Bq.m-3 with an average values of 1359.8 Bq.m-3 and 2338.3 Bq.m-3 for 5 cm and 10 cm depths respectively. Maximum radon level was found at the location near to the river (site S4) while the minimum radon level was found at residential area (site S2). Radium contents were ranged from 0.42 to 1.62 Bq.kg-1, from 0.85 to 2.15 Bq.kg-1 and from 1.38 to 4.86 Bq.kg-1 with average values of 1.04, 1.43 and 2.46 Bq.kg-1 for surface, 5 cm and 10 cm depths respectively. Radon exhalation rates as a function of area and mass were also obtained. Surface exhalation rate ranged from 0.05 to 0.18 Bq.m-2.h-1, from 0.09 to 0.24 Bq.m-2.h-1 and from 0.15 to 0.53 Bq.m-2.h-1 with average values 0.11, 0.16 and 0.27 Bq.m-2.h-1 for surface, 5 cm and 10 cm depths respectively. Mass exhalation rate ranged from 0.02 to 0.06 Bq.kg-1.h, from 0.03 to 0.08 Bq.kg-1.h and from 0.05 to 0.18 Bq.kg-1.h with average values 0.04, 0.05 and 0.09 Bq.kg-1.h for surface, 5 cm and 10 cm depths respectively. The results obtained from this study indicate that the region background radiation levels are within the natural limits.
Examining Stress and Pet/Stuffed Animal Attachment Levels with College Students

Research shows that stress affects over 50% of undergraduates’ health on university campuses (Crump & Derting, 2015). One of the reasons is due to the developmental transition between college and adulthood, which is usually confronted with stressful situations as students prepare to adapt in the new environment (Kim, Noh, & Park, 2015). While pets and stuffed animals are popular in society, there has been little research conducted to investigate if owning pets and/or stuffed animals relates to lower stress levels. The first hypothesis was to determine if pet ownership relates to lower perceived stress in college students. The second hypothesis was to determine if stuffed animal ownership relates to lower perceived stress in college students. Researchers also investigated if college students have a similar attachment level between pets and stuffed animals. There were some significant correlations discovered that provided new information on pet/stuffed animal attachment. Further implications of the results will be discussed.
The Effectiveness of Monetary Transmission Channels: The Case of Central and Eastern European Transition Economies

Many factors including government actions, the depth of financial markets, the structure of banking sector, capital movements, etc. affect the functioning of the monetary transmission mechanism. Thus, the determination of the channels playing an active role in the transmission mechanism is of vital importance for making policy decisions aimed at ensuring price stability. The present study aimed at investigating the effectiveness of the monetary transmission channels in Central and Eastern European (MDA) transition economies. In this regard, the study tested the effects of the monetary transmission channels in MDA transition economies in the 1995:01-2012:12 period on macroeconomic variables. Firstly, the Vector Autoregression Analysis (VAR) was carried out in order to determine the short-term dynamics of the effects of the transmission channels on macroeconomic variables. Secondly, the long-term dynamics of the effects of transmission channels on macroeconomic variables were searched via autoregressive distributed lag (ARDL) analysis. It was concluded in study that financial development and exchange rate were the most efficient channels on economic variables in most of the said economies.
Characterization and Expression Levels of Protease Enzymes at Different Developmental Stages of Siamese Fighting Fish (Betta splendens Regan, 1910)

Characterization of total proteases, trypsin and chymotrypsin were performed at pH 2 12 and temperatures 20-80°C in three life stages of Siamese fighting fish (Betta splendens Regan, 1910). At least fourteen protease activities were detected, including seven acidic (pH levels 2, 4 and 5-6), one neutral (pH 7), and six alkaline (pH levels 8-12) activities in the optimal temperature range of 30-60°C. The neutral and alkaline pH profiles were different between sexes during the on-growing stage (1.5 month-old). The acidic proteases played a major role in digestion in the early life stage (10-day-old), while the alkaline proteases became more important toward older stages. Trypsin and chymotrypsin showed similar characteristics with at least five activities observed. For trypsin, activity was detected with pH 7 and 8 at 50°C, and pH 10 at 30, 50 and 60°C. For chymotrypsin, activity was found at pH levels 7 and 8 at 50°C, and pH 10 at 30, 40 and 50°C. Regardless of sex and age, the most suitable conditions for studying digestive enzyme activities in general were at pH 8 and 50°C for total proteases, pH 7-8 and 50°C or pH 10 and 30-35°C for trypsin and pH 7-8 and 50°C or pH 10 and 40°C for chymotrypsin. Trypsin and chymotrypsin are important proteases showing similar general optimal conditions to that of total proteases. This information provides elementary knowledge for studying protein digestibility by in vitro techniques and for determining growth performance quality using digestive enzyme markers in Siamese fighting fish.

Auditor Tenure, Auditor Industry Expertise, and Audit Report Lag: Evidences of Iran

The findings of theoretical investigations indicate that short-term auditor tenures may contribute to further audit report lags (ARLs). On the other hand, auditor industry expertise represents one of the determinant factors contributing to audit quality, which has been widely studied in numerous researches. Indeed, the better the quality of audit, the less delayed would be the audit report. As such, aiming at investigating the association between auditor tenure and ARL on the one hand, and studying the adjusting effect of auditor industry expertise on the other hand, the present research investigated 141 firms operating within 25 industries during 2010-2014. Chaw and Hausman Test results indicated, at 5% level of significance, that the corresponding regression model should be assessed with consistent effects. Furthermore, undertaking multivariate linear regression analysis, the research results implied no significance association between auditor tenure and ARL. In fact, the first hypothesis that auditor tenure is negatively related to ARL was rejected. On the other hand, the second hypothesis that auditor industry expertise may attenuate the association of auditor tenure and ARL was also rejected, meaning that, even with auditor industry expertise considered, a significant relationship between auditor tenure and audit report lag could not be recognized.
Uncertainty in Entrepreneurship and Management Studies: A Systematic Literature Review

Despite the crucial role of uncertainty in entrepreneurship and management studies, the characteristics of uncertainty, its relationship with risk, and the sources of uncertainty affecting firms’ activities still require investigation. Extant literature lacks systematization, and concepts like risk and uncertainty are interchangeably used. The issue of uncertainty is present in very different fields of research but with different nuances and sometimes conflicting approaches. This work contextualises the concept of uncertainty in strategic management and entrepreneurship, because in both fields actors make decisions impacting on the survival and long run performance of their organisations. These decisions take place in a context shrouded in either high risk or uncertainty. We systematically analyse 96 papers and 28 books, and purposely integrate the economics, entrepreneurship, and organizational perspectives into our review. We contribute to extant knowledge by systematizing the literature about uncertainty. Firstly, we disentangle its construct from the construct of risk. Secondly, we reveal its complex nature, as a context at the interface between the external and the internal environment. Finally, we link this conceptualisation of uncertainty to the formation of opportunities in the processes of strategic management and entrepreneurship.
The near-infrared spectral index of Sagittarius A* derived from Ks- and H-band flare statistics

Context. The near-infrared (NIR) counterpart of Sagittarius A* (SgrA*) at the position of the 4 x 10(6) M(circle dot) supermassive black hole at the center of the Milky Way has strongly varying flux densities. The broad-band near-infrared spectral index is an essential parameter to determine the underlying emission mechanism for the observed flare emission. Aims. We present a method to derive the NIR spectral index of SgrA* between the H- and Ks-band from the statistics of the observed flare emission. Our spectral index derivation is therefore based on an unprecedentedly large timebase of about seven years of monitoring the infrared counterpart of SgrA*. Methods. We examined NIR light curves of SgrA* in the H- and Ks-band and established flare number distributions as a function of peak flare flux. We assume that in both bands the same optically thin dominant emission mechanism is at work and produces similar number distributions of flares. We cross-correlated these histograms and determined a statistical expectation value of the H-Ks-band spectral index during the bright phases of SgrA*. Results. With this new method, we can independently confirm that the expectation value of the spectral index for brighter flares is consistent with alpha = -0.7 (with the flux density (F(nu) proportional to nu(+alpha))) which is expected for pure synchrotron radiation. We find a tendency for weaker flares to exhibit a steeper spectrum. Conclusions. We conclude that the distribution of spectral indices as a function of Ks-band flux density can successfully be described by an exponential cutoff proportional to expleft perpendicular-(nu/nu(0))(0.5)right perpendicular because of synchrotron losses, with nu(0) being a characteristic cutoff frequency. Varying nu(0) between the NIR and sub-mm domain and assuming a sub-mm flux density variation of about one Jansky and optically thin spectral indices of alpha = -0.7 +/- 0.3 explains the observed spectral properties of SgrA* in the NIR.
Dark matter–radiation interactions: the impact on dark matter haloes

Interactions between dark matter (DM) and radiation (photons or neutrinos) in the early Universe suppress density fluctuations on small mass scales. Here, we perform a thorough analysis of structure formation in the fully non-linear regime using N-body simulations for models with DM–radiation interactions and compare the results to a traditional calculation in which DM only interacts gravitationally. Significant differences arise due to the presence of interactions, in terms of the number of low-mass DM haloes and their properties, such as their spin and density profile. These differences are clearly seen even for haloes more massive than the scale on which density fluctuations are suppressed. We also show that semi-analytical descriptions of the matter distribution in the non-linear regime fail to reproduce our numerical results, emphasizing the challenge of predicting structure formation in models with physics beyond collisionless DM.
