Comparative study of load distribution ratio of various piled raft foundations based on coupled stiffness matrix
Authors: Kim Dohyun , Jeong Sangseom 
Published: September 2019

SummaryLoad distribution ratio of piled raft foundation was investigated based on an interactive foundation analytical method that considers the coupling effect between the stiffness of the superstructure, the piled raft, and the soil. Series of numerical analysis was performed to verify the proposed analytical routine in comparison with various methods and field measurements. Through the comparative studies between various piled rafts with different aspects, it was found that the proposed analytical method derived accurate results in structural response compared with actual field data, in settlement, load distribution ratio, and raft bending moment. And it was also found that the proposed analytical method was capable of considering interaction between superstructure and foundation in predicting the behavior of building structures. As a result, it was found that in most cases, the pile in the piled raft foundation supports a majority portion of the structural load. However, for cases where the length of the pile was short and acts as a short column, the load distribution ratio between raft and pile may be overturned and shows significantly different behavior and load distribution ratio.
Tip‐vortex breakdown of wind turbines subject to shear
Authors: Kleusberg Elektra , Benard Sabrina , Henningson Dan S. 
Published: September 2019

AbstractSheared velocity profiles pervade all wind‐turbine applications, thus making it important to understand their effect on the wake. In this study, a single wind turbine is modeled using the actuator‐line method in the incompressible Navier–Stokes equations. The tip vortices are perturbed harmonically, and the growth rate of the response is evaluated under uniform inflow and a linear velocity profile. Whereas previous investigations of this kind were conducted in the rotating frame of reference, this study evaluates the excitation response in the fixed frame of reference, thus necessitating a frequency transformation. It is shown that increasing the shear decreases the spatial growth rate in the upper half of the wake while increasing it in the lower half. When scaled with the local tip vortex parameters, the growth rate along the entire azimuth collapses to a single value for the investigated wavenumbers. We conclude that even though the tip‐vortex breakdown is asymmetric in sheared flow, the scaled growth rates follow the behavior of axisymmetric helical vortices. An excitation amplitude reduction by an order of magnitude extends the linear growth region of the wake by one radius for uniform inflow. In the sheared setup, the linear growth region is extended further in the top half than in the bottom half because of the progressive distortion of the helical tip vortices. An existing model to determine the stable wake length was shown to be in close agreement with the observed numerical results when adjusted for shear.

AbstractAimsThis study aimed to disentangle tree-crop-fertilizer interactions in agroforestry systems, which has been suggested as an entry point for sustainable intensification of smallholder farming systems in sub-Saharan Africa (SSA). Although tree-crop systems generate multiple economic and ecological benefits, tree-crop competition commonly occurs. We hypothesized that mineral fertilizers affect facilitative and competitive interactions differently in tree-crop systems.MethodsTree-crop-fertilizer interactions were explored for wheat growing underFaidherbia albida,and maize growing underAcacia tortilisandGrevillea robustathrough omission trials of nitrogen (N) and phosphorus (P) in open fields and fields under tree canopy, using a split plot design. The experiments were conducted in Ethiopia and Rwanda, replicated four times, and over two seasons.ResultsOur results demonstrated that the presence ofF. albida significantlyimproved N and P use efficiencies, leading to significantly higher (P < 0.001) grain yields in wheat. This tree species contributed around 64 kg ha−1 yr.−1of mineral N. The P use efficiency of wheat underF. albidawas double that of open field wheat. By contrast,G. robustaandA. tortilistrees lowered nutrient use efficiencies in maize, leading to significantly less maize grain yields compared with open fields receiving the same fertilization. Probabilities of critically low crop yields and crop failure were significantly greater for maize growing under the canopy of these species.ConclusionsOur results showed that recommended fertilizer rates led to facilitative interaction only withF. albida,highlighting that fertilizer recommendations need to be adapted to agroforestry systems.

Published: September 2019

Abstract
Complex heat treatment operations and advanced manufacturing processes such as laser or electron-beam welding will see the metallic workpiece experience a considerable range of temperatures and heating/cooling rates. These intrinsic conditions will have a significant bearing upon the microstructure of the material, and in turn upon the thermo-mechanical properties. In this work, a diffusion-based approach to model the growth and shrinkage of precipitates in the alpha + beta field of the common titanium alloy Ti-6Al-4V is established. Further, the numerical model is extended using a JMA-type approach to explore the dependency of the beta-transus temperature on extremely high heating rates, whereby dissolution alone is too slow to accurately describe the alpha to beta-phase transformation. Experimental heat treatments at rates of 5, 50, and 500 °C/s were performed, and metallographic analysis of the samples was used to validate the numerical modeling framework predictions for lamellar shrinkage, while data from the literature has been used to evaluate the numerical modeling framework for the growth of equiaxed microstructures. The agreement between measurements and numerical predictions was found to be good.
MODELLING ZERO-INFLATED COUNT DATA WITH A SPECIAL CASE OF THE GENERALISED POISSON DISTRIBUTION
Authors: Calderín-Ojeda Enrique , GóMez-Déniz Emilio , Barranco-Chamorro Inmaculada 
Published: September 2019

AbstractA one-parameter version of the generalised Poisson distribution provided by Consul and Jain (1973) is considered in this paper. The distribution is unimodal with a zero vertex and over-dispersed. A generalised linear model related to this distribution is also presented. Its parameters can be estimated by using a Fisher-Scoring algorithm which is equivalent to iteratively reweighted least squares. Due to its flexibility and capacity to describe highly skewed data with an excessive number of zeros, the model is suitable to be applied in insurance settings as an alternative to the negative binomial and zero-inflated model.
The Essence of the Fundamental Rights to Privacy and Data Protection: Finding the Way Through the Maze of the CJEU’s Constitutional Reasoning
Authors: Brkan Maja 
Published: September 2019

AbstractIn the constitutional shaping of the concept of essence of fundamental rights, the case law of the Court of Justice of the EU (“CJEU” or “the Court”) in the field of privacy and data protection plays a crucial role. The Court’s interpretation of this notion had a considerable impact not only jon perception of the essence in other fields of law, but also on the constitutional doctrine more generally. This Article focuses on specificities of the notion of essence of fundamental rights to privacy and the protection of personal data from Articles 7 and 8 of the Charter of Fundamental Rights of the EU. After a general analysis, situating this notion into the framework of multi-level protection of fundamental rights in Europe, the Article addresses further interpretative challenges relating to the essence in the Court’s case law. At the core of the analysis are the Schrems and Digital Rights Ireland cases, where the CJEU developed, for the first time, the modalities of the breach of essence of fundamental rights to privacy and data protection and laid down constitutional foundations for interpretation of this notion. Further jurisprudence, including the Tele2 Sverige and Opinion 1/15 cases, is analyzed as an example of fine-tuning of the CJEU’s approach towards the normative understanding of this concept. Against this backdrop, the Article elaborates on the importance of insights in the fields of privacy and data protection for the general constitutional understanding of the concept of essence and proposes a generalized method for determination of infringement of essence in fundamental rights jurisprudence.

AbstractObjectivesTo assess the perception of Ghanaian medical students about factors influencing their career interest in psychiatry and to explore gender differences in these perceptions.MethodsThis is a cross-sectional quantitative survey of 5th and 6th year medical students in four public medical schools in Ghana. Data were analyzed with descriptive and inferential statistics using SPSS version 20.ResultsResponses were obtained from 545 medical students (response rate of 52%). Significantly, more male medical students expressed that stigma is an important consideration for them to choose or not to choose a career in psychiatry compared to their female counterparts (42.7%v.29.7%, respectively). Over two-thirds of the medical students perceived that psychiatrists were at risk of being attacked by their patients, with just a little over a third expressing that risk was an important consideration for them to choose a career in psychiatry. There were no gender differences regarding perceptions about risk. Around 3 to 4 out of 10 medical students will consider careers in psychiatry if offered various incentives with no gender differences in responses provided.ConclusionOur study presents important and novel findings in the Ghanaian context, which can assist health policy planners and medical training institutions in Ghana to formulate policies and programs that will increase the number of psychiatry residents and thereby increase the psychiatrist-to-patient ratio in Ghana.

Published: September 2019

AbstractThe ancient landscapes surrounding Cyrene, which have been incredibly well preserved for centuries, have suffered more destructions in the past 7 or 8 years than in the whole of the last millennium. Urban encroachment, strong demographic pressure, unsustainable exploitation of resources and unplanned growth of infrastructures and services are threatening the archaeological heritage of this splendid site. The Department of Antiquities (DoA) has always struggled against these phenomena, but today the destructions are so great that the DoA is often powerless to act. This paper continues previous works on the damage to the Cyrenean necropoleis after 2011(Abdulkariem and Bennett, 2014; Al Raeid et al. 2016; Menozzi, Di Valerio et al. 2017; Menozzi, Tamburrino et al. 2017) and proposes strategies to help, on the basis of a preliminary report organised by the Mission of the University of Chieti in collaboration with the Departments of Antiquities of Cyrene and Tripoli, as requested by UNESCO. This preliminary step towards further improvements and needs to be discussed with other institutions and missions. The first part presents a proposal for controlling the core and buffer zones around Cyrene; the second part is an update on the recent damages to the necropoleis.
Modelling organisational vicarious liability
Authors: Witting Christian 
Published: September 2019

AbstractThis paper identifies two paradigms of vicarious liability. One is an established paradigm of ‘liberal agency’ found in cases where owner-managers ‘act through’ workers, with whom they have personal relations, in undertaking work tasks. The second paradigm is found in cases concerning bureaucratic organisations, which are characterised by chains of command and variegated decision-making procedures. Courts have grounded organisational responsibility in features such as structure, hierarchy, and control, which this paper uses to construct a model of the ‘deterrable organisation’. The deterrable organisation has important capacities to effect change in behaviour that courts rely on in order to prevent worker wrongdoing. The paper tests the viability of the model against the empirical literature and argues that courts could improve outcomes by a more targeted use of powers to award remedies.

AbstractThe aim of this network meta-analysis is to compare bone mineral density (BMD) changes among different osteoporosis prevention interventions in postmenopausal women. We searched MEDLINE, Embase and Cochrane Library from inception to 24 February 2019. Included studies were randomised controlled trials (RCT) comparing the effects of different treatments on BMD in postmenopausal women. Studies were independently screened by six authors in three pairs. Data were extracted independently by two authors and synthesised using Bayesian random-effects network meta-analysis. The results were summarised as mean difference in BMD and surface under the cumulative ranking (SUCRA) of different interventions. A total of ninety RCT (10 777 participants) were included. Ca, vitamin D, vitamin K, oestrogen, exercise, Ca + vitamin D, vitamin D + vitamin K and vitamin D + oestrogen were associated with significantly beneficial effects relative to no treatment or placebo for lumbar spine (LS). For femoral neck (FN), Ca, exercise and vitamin D + oestrogen were associated with significantly beneficial intervention effects relative to no treatment. Ranking probabilities indicated that oestrogen + vitamin D is the best strategy in LS, with a SUCRA of 97·29 % (mean difference: +0·072 g/cm2compared with no treatment, 95 % credible interval (CrI) 0·045, 0·100 g/cm2), and Ca + exercise is the best strategy in FN, with a SUCRA of 79·71 % (mean difference: +0·029 g/cm2compared with placebo, 95 % CrI –0·00093, 0·060 g/cm2). In conclusion, in postmenopausal women, many interventions are valuable for improving BMD in LS and FN. Different intervention combinations can affect BMD at different sites diversely.
The application of Neodymium isotope as a chronostratigraphic tool in North Pacific sediments
Authors: Zhang Wenfang , Li Gaojun , Chen Jun 
Published: September 2019

AbstractIt has been suggested that dust generation was closely linked to the development of global ice sheets and/or cooling. This feature has allowed Asian dust to be a potential chronostratigraphic tool in North Pacific Ocean (NPO) sediments. The orbital-scale age control in NPO sediments is usually established by adjusting the benthic-foraminiferal δ18O to the global δ18O stack (LR04). However, it would become difficult if the sediments did not contain enough foraminifera. This study investigates Sr and Nd isotopes, trace elements, mineralogy and grain size of the ‘operationally defined aeolian dust’ (ODED) extracted from the sediments recovered at Ocean Drilling Program (ODP) site 1209B on the Shatsky Rise in the NPO covering the past five glacial–interglacial cycles. The geochemical results show that the ODED at site 1209B is actually a mixture of Asian dust and volcanic ash. The variation of Nd isotope mimics the cycles of glacial–interglacial ice sheets as revealed by the global benthic foraminifera’s oxygen isotope stack (LR04) over the past 500 ka. The low (high)ϵNdvalues corresponded with the cool (warm) periods. We propose thatϵNdvariation reflects the evolving aeolian dust in site 1209 sediments. The excellent agreement betweenϵNdvalues at site 1209B and LR04 stack over the past 500 ka allows establishing the orbital-timescale age control by tuningϵNdto the LR04 curve. We thus propose that Nd isotope provides a chronostratigraphic technique in NPO sediments, especially for sediments with a limited amount of foraminifera.
Is Gurney's pitta Hydrornis gurneyi on the brink of extinction?

Published: September 2019

AbstractThe remaining large patches of lowland forest in Tanintharyi, southern Myanmar, are the last global stronghold for the Endangered Gurney's pitta Hydrornis gurneyi. Except for a few individuals, the remaining population is now restricted to this forest, below 150 m altitude, mostly within the Nga Wun, Lenya, and Parchan Reserved Forests. However, as in much of South-east Asia, Tanintharyi has been subjected to extensive deforestation, particularly for oil palm cultivation. The aim of this research was to determine the extent of remaining habitat suitable for Gurney's pitta. During January–October 2016 we revisited 142 locations (of 147) where the species was detected during 2003–2012, and found it in only 41 of those locations (29%); in all other locations the forest had been cleared. We measured the decline of suitable habitat since 1999 by examining all available intact forest in areas with elevations < 150 m and slope < 10 °. In less than 2 decades suitable habitat has declined from 3,225 to 656 km2 (80%). Protection of remaining lowland forest is now critical. Although the expansion of oil palm cultivation has slowed since its peak in the early 2000s, two national parks proposed by the Myanmar government in 2002, which would potentially offer legal protection for most of the remaining Gurney's pitta habitat, remain on hold because of political uncertainties. We recommend an alternative conservation approach for this species, based on an Indigenous Community Conserved Area model, and further research to improve knowledge of the species and to determine how it could be saved from extinction.

Abstract
The spread of the Zika virus (ZIKV) in the Americas led to large outbreaks across the region and most of the Southern hemisphere. Of greatest concern were complications following acute infection during pregnancy. At the beginning of the outbreak, the risk to unborn babies and their clinical presentation was unclear. This report describes the methods and results of the UK surveillance response to assess the risk of ZIKV to children born to returning travellers. Established surveillance systems operating within the UK – the paediatric and obstetric surveillance units for rare diseases, and national laboratory monitoring – enabled rapid assessment of this emerging public health threat. A combined total of 11 women experiencing adverse pregnancy outcomes after possible ZIKV exposure were reported by the three surveillance systems; five miscarriages, two intrauterine deaths and four children with clinical presentations potentially associated with ZIKV infection. Sixteen women were diagnosed with ZIKV during pregnancy in the UK. Amongst the offspring of these women, there was unequivocal laboratory evidence of infection in only one child. In the UK, the number and risk of congenital ZIKV infection for travellers returning from ZIKV-affected countries is very small.
Joseph Edkins and the “Discovery” of Early Chinese: the linguistic ideas behind the first (partial) reconstruction of the sound system of Early Chinese
Authors: ORLANDI GIORGIO 
Published: September 2019

AbstractThe ‘discovery’ of early Chinese, and its subsequent reconstruction, have allowed the modern linguist to reach a wide range of firm conclusions about the Chinese language and its position within the Tibeto-Burman family. Reverend Joseph Edkins (1823–1905) should be credited with initial work on early Chinese as the ancestor language of the various Sinitic languages, and with its first partial reconstruction. This article is an attempt to supply at least a first historical guide for those interested in obtaining a better understanding of the implicit discovery of Sinitic and the first reconstructions of early Chinese.
Folic acid deficiency declined substantially after introduction of the mandatory fortification programme in Queensland, Australia: a secondary health data analysis

Published: September 2019

AbstractObjective:To investigate the prevalence of folic acid deficiency in Queensland-wide data of routine laboratory measurements, especially in high-risk sub-populations.Design:Secondary health data analysis.Setting:Analysis of routine folic acid tests conducted by Pathology Queensland (AUSLAB).Participants:Female and male persons aged 0–117 years with routine folic acid testing between 1 January 2004 and 31 December 2015. If repeat tests on the same person were conducted, only the initial test was analysed (n 291 908).Results:Overall the prevalence of folic acid deficiency declined from 7·5 % before (2004–2008) to 1·1 % after mandatory folic acid fortification (2010–2015; P < 0·001) reflecting a relative reduction of 85 %. Levels of erythrocyte folate increased significantly from a median (interquartile range) of 820 (580–1180) nmol/l in 2008 before fortification to 1020 (780–1350) nmol/l in 2010 (P < 0·001) after fortification. The prevalence of folic acid deficiency in the Indigenous population (14 792 samples) declined by 93 % (17·4 v. 1·3 %; P < 0·001); and by 84 % in non-Indigenous residents (7·0 v. 1·1 %; P < 0·001). In a logistic regression model the observed decrease of folic acid deficiency between 2008 and 2010 was found independent of gender, age and ethnicity (ORcrude = 0·20; 95 % CI 0·18, 0·23; P < 0·001; ORadjusted = 0·21; 95 % CI 0·18, 0·23; P < 0·001).Conclusions:While voluntary folic acid fortification, introduced in 1995, failed especially in high-risk subgroups, the 2009 mandatory folic acid fortification programme coincided with a substantial decrease of folic acid deficiency in the entire population.

AbstractIdiopathic basal ganglia calcification-1 (IBGC1) is an autosomal dominant disorder characterized by calcification in the basal ganglia, which can manifest a range of neuropsychiatric symptoms, including parkinsonism. We herein describe a 64-year-old Japanese IBGC1 patient with bilateral basal ganglia calcification carrying a novel SLC20A2 variant (p.Val322Glufs*92). The patient also presented with dopa-responsive parkinsonism with decreased dopamine transporter (DAT) density in the bilateral striatum and decreased cardiac 123I-meta-iodobenzylguanidine uptake.
