Negotiation of meaning and negotiation of form in Chinese EFL classroom discourse
Authors: Wang Qing
Published: June 2018

In recent decades, numerous empirical studies have been conducted on negotiation of meaning and negotiation of form, but few have focused on examining the distinction between the two negotiation types. This qualitative study aims at distinguishing the two negotiation types by analyzing teacher-student dyadic interaction. Three English teachers and their students from a university in China participated in the study. The classroom interaction between the teachers and their students was recorded over 11 weeks, and the data analyzed for the present study totaled 13 hours and 50 minutes. Results indicate that (1) in terms of teacher intentions, the two negotiation types differ considerably: whereas negotiation of meaning is conversational and didactic in function, negotiation of form is solely didactic; (2) regarding retrieval processes and types of learner uptake, the two negotiation types differ slightly except for when negotiation of meaning is didactic in function. The findings thus reveal some issues to address regarding the function of negotiation of meaning.

Published: June 2018

The genus Thyroptera is composed of small insectivorous bats widely distributed in the Neotropics. Thyroptera lavali is an Amazonian species distributed in lowland rainforests of Peru, Ecuador and Brazil and in the Venezuelan Eastern Llanos. The goal of this study was to document new records of T. lavali for Venezuela and update the geographic distribution of Thyroptera species in that country. Based on specimens deposited in Venezuelan museums, we report the first record of T. lavali for the Guiana Shield and the second record for the Venezuelan Llanos. The external and cranial measurements of the analyzed specimens fall within the range previously reported for T. lavali; likewise, the qualitative characters are similar to what is known for the species. Additionally, derived from a search of records in databases, we report the first specimens of Thyroptera discifera for the Orinoco river basin. We confirm the presence of three species in Venezuela: T. discifera, distributed in the Cordillera de la Costa and Central and Western Llanos; Thryoptera tricolor, occurring in the Andes, Deltaic System and the Guiana Shield and T. lavali, recorded in the Eastern Llanos, Deltaic System and the Guiana Shield.

Lost in Translation: Local Relief Provision and Historiographical Imperialism
Authors: Reeves Caroline
Published: June 2018

The historiographical record of charity, both visual and written, has long been appropriated by philanthro-imperialists intent on using material aid to further their own agendas. International actors committed to bringing their own priorities and prerogatives with them overseas have ignored or intentionally erased accounts of local, particularly non-Western, humanitarian and charitable initiatives. In some contexts, local communities have also chosen to erase their own charitable history. This article uncovers one such hidden charitable tradition, that of pre-Maoist China. I discuss indigenous Chinese charitable work and its interplay with Western charitable actors and activities at the turn of the twentieth century, at the height of the New Imperialism (c. 1870–1914) to explore two little-recognized facets of the relationship between charity and imperialism: the erasure of local traditions of charity in the annals of imperialist powers and the importance of language in the preservation and validation of these traditions.
Reconstructing chemical plumes from stand-off detection data of airborne chemicals using atmospheric dispersion models and data fusion
Authors: Björnham Oscar , Grahn Håkan , Brännström Niklas
Published: June 2018

Stand-off detection of airborne chemical compounds has proven to be a useful method that is gaining popularity following technical progress. There are obvious advantages compared to in situ measurements when it comes to the security aspect and the ability to measure at locations otherwise hard to reach. However, an inherent limitation in many of the stand-off detection techniques lies in the fact that the measured signal from a chemical depends nonlinearly on the distance to the detector. Furthermore, the measured signal describes the summation of the responses from all chemicals spatially distributed in the line of sight of the instrument. In other words, the three dimensional extension of the chemical plume is converted into a two-dimensional image. Not only is important geometric information per se lost in this process, but the measured signal strength itself depends on the unknown plume distribution which implies that the interpretation of the observation data suffers from significant uncertainty. In this paper we investigate different and novel approaches to reconstruct the original three-dimensional distribution and concentration of the plume by implementation of atmospheric dispersion models and numerical retrieval methods. In particular our method does not require a priori assumptions on the three-dimensional distribution of the plume. We also strongly advocate the use of proper constraints to avoid unphysical solutions being derived (or post-process ‘adjustments’ to correct unphysical solutions). By applying such a reconstruction method, both improved and additional information is obtained from the original observation data, providing important intelligence to the analysts and decision makers.
A hidden Markov regime-switching smooth transition model
Authors: Elliott Robert J. , Siu Tak Kuen , Lau John W.
Published: June 2018

In this paper, we develop a new class of parametric nonlinear time series models by combining two important classes of models, namely smooth transition models and hidden Markov regime-switching models. The class of models is general and flexible enough to incorporate two types of switching behavior: smooth state transitions and abrupt changes in hidden states. The estimation of the hidden states and model parameters is performed by applying filtering theory and a filter-based expectation-maximization (EM) algorithm. Applications of the model are illustrated using simulated data and real financial data. Other potential applications are mentioned.
Assessment of Support Conditions of Concrete Pavement Using FWD Deflection Basin Data
Authors: Vennapusa Pavana K. R. , Zhang Yang , White David J.
Published: June 2018

Results from a field forensic investigation conducted using a falling weight deflectometer (FWD) and visual observations on a jointed concrete pavement that showed premature distresses are presented in this article. At the time of testing, the pavement was six years old and was supported on a crushed limestone granular base underlain by cohesive natural or fill subgrade. The primary objective of the field investigation was to assess whether the foundation support conditions contributed to the distresses observed. FWD tests were conducted on 140 panels over an 830-m-long section of which 25 panels showed distress. The FWD deflection basin data was used to calculate several index parameters, which showed statistically significant differences between the cracked and the uncracked slabs, which suggests that the foundation layer properties were comparatively weaker under the cracked slabs. Visual observations showed that some of the distresses were related to potential lateral movement of the slopes next to the pavement.
MECHANISMS IN ENDOCRINOLOGY: Hormonal regulation of spermatogenesis: mutant mice challenging old paradigms
Authors: Huhtaniemi Ilpo
Published: June 2018

The two pituitary gonadotrophins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), and in particular LH-stimulated high intratesticular testosterone (ITT) concentration, are considered crucial for spermatogenesis. We have revisited these concepts in genetically modified mice, one being theLH receptor(R)-knockout mouse (LuRKO), the other a transgenic mouse expressing in Sertoli cells a highly constitutively active mutatedFshr(Fshr-CAM). It was found that full spermatogenesis was induced by exogenous testosterone treatment in LuRKO mice at doses that restored ITT concentration to a level corresponding to the normal circulating testosterone level in WT mice, ≈5 nmol/L, which is 1.4% of the normal high ITT concentration. When hypogonadal LuRKO and Fshr-CAM mice were crossed, the double-mutant mice with strong FSH signaling, but minimal testosterone production, showed near-normal spermatogenesis, even when their residual androgen action was blocked with the strong antiandrogen flutamide. In conclusion, our findings challenge two dogmas of the hormonal regulation of male fertility: (1) high ITT concentration is not necessary for spermatogenesis and (2) strong FSH stimulation can maintain spermatogenesis without testosterone. These findings have clinical relevance for the development of hormonal male contraception and for the treatment of idiopathic oligozoospermia.
Race on Both Sides of the Razor
Authors: Keel Terence D.
Published: June 2018

The proliferation of studies declaring that there is a genetic basis to health disparities and behavioral differences across the so-called races has encouraged the opponents of social constructionism to assert a victory for scientific progress over political correctness. I am not concerned in this essay with providing a response to critics who believe races are expressions of innate genetic or biological differences. Instead, I am interested in how genetic research on human differences has divided social constructionists over whether the race concept in science can be used for social justice and redressing embodied forms of discrimination. On one side, there is the position that race is an inherently flawed concept and that its continued use by scientists, medical professionals, and even social activists keeps alive the notion that it has a biological basis. On the other side of this debate are those who maintain a social constructionist position yet argue that not all instances of race in science stem from discriminatory politics or the desire to prove that humans belong to discrete biological units that can then be classified as superior or inferior. I would like to shift this debate away from the question of whether race is real and move instead toward thinking about the intellectual commitments necessary for science to expose past legacies of discrimination.

Stability analyses of deterministic and stochastic SEIRI epidemic models with nonlinear incidence rates and distributed delay
Authors: Zhang Hong , Xia Juan , Georgescu Paul
Published: June 2018

In this paper, deterministic and stochastic SEIRI epidemic models featuring a distributed latent period and general, unspecified nonlinear incidence and growth rates for the susceptible class are proposed and investigated from a stability viewpoint. By applying Lyapunov–LaSalle invariance principle, we first obtain sufficient conditions for the global stability of equilibria of the deterministic model. On the basis of this result, we subsequently derive sufficient conditions for asymptotic stability of the stochastic model. Finally, numerical simulations are given to illustrate the previously obtained theoretical framework.

Dynamics of a host-pathogen model with constant mortality rate
Authors: Din Qamar
Published: June 2018

In this paper, we propose a discrete-time host-pathogen model and study its qualitative behavior. The model is for the spread of an infectious disease with constant mortality rate of hosts. Moreover, the time-step is equal to the duration of the infectious phase and the host mortality is taken at some constant rate d >0. This two-dimensional discrete-time epidemic model has complex dynamical behavior. More precisely, we investigate the existence and uniqueness of positive equilibrium point, boundedness character, local and global asymptotic stability of unique positive equilibrium point, and the rate of convergence of positive solutions that converge to unique positive equilibrium point. Numerical simulations are provided to illustrate our theoretical results.

Modeling the effect of deforestation caused by human population pressure on wildlife species
Authors: Lata Kusum , Misra Arvind Kumar Kumar , Shukla Jang Bahadur Bahadur
Published: June 2018

The increase in human population has posed several problems for the ecosystem. One of these problems is the decrease in forestry resources, which leads to decline in forest area and thus threaten the survival of wildlife species as the intraspecific competition among the wildlife species increases. Moreover, these wildlife species can also be apprehended easily by poachers and smugglers. This affects the biodiversity across the globe. In this paper, we have proposed and analyzed a nonlinear mathematical model to see the effect of deforestation caused by population and its pressure on wildlife species. The analysis of proposed model reveals that, as the parameters in respect to the increase in population pressure increase, wildlife species decrease. To support analytical findings, we have done numerical simulation.
Growth Hormone Deficiency Causing Micropenis: Lessons Learned From a Well-Adjusted Adult
Authors: Lee Peter A. , Mazur Tom , Houk Christopher P. , Blizzard Robert M.
Published: June 2018

This report of a 46,XY patient born with a micropenis consistent with etiology from isolated congenital growth hormone deficiency is used to (1) raise the question regarding what degree testicular testosterone exposure to the central nervous system during fetal life and early infancy has on the development of male gender identity, regardless of gender of rearing; (2) suggest the obligatory nature of timely full disclosure of medical history; (3) emphasize that virtually all 46,XY infants with functional testes and a micropenis should be initially boys except some with partial androgen insensitivity syndrome; and (4) highlight the sustaining value of a positive long-term relationship with a trusted physician (R.M.B.). When this infant presented, it was commonly considered inappropriate to gender assign an infant male whose penis was so small that an adult size was expected to be inadequate, even if the karyotype was 46,XY, and testes were functional. Concomitantly, female gender assignment was considered the appropriate decision, believing that parental rearing in the assigned gender was considered the major factor determining established adult gender identity. Full disclosure of medical information was considered inappropriate. Progress in appreciating the complexities of gender identity development, which is not yet completely understood, and sexuality, coping ability, and outcome data has resulted in a change of practice in initial gender assignment. A 46,XY individual with functional testes and verified androgen responsiveness should be assigned and reared as male, regardless of penis size. Without androgen responsiveness, the multiple factors must be carefully considered and disclosed.

Authors: Gillet Sérgio Augusto da Costa , Portela Vinícius José Rockenbach
Published: June 2018

O avanço tecnológico no campo das inteligências artificiais (IAs) vem crescendo exponencialmente, aventando a possibilidade que máquinas possam tomar decisões, inclusive na seara jurídica. Com esta realidade, este artigo objetiva a lançar algumas ideias entre a motivação das decisões judiciais e a utilização de IAs para julgar litígios. Utilizando-se do método indutivo, discorreu-se sobre ambos os temas de modo a encontrar pontos de encontro e de ruptura na capacidade de IAs julgadoras poderem motivar decisões judiciais em atenção às diretrizes legais e constitucionais. Conclui-se que as IAs atuais ainda não são totalmente capazes de atender a essas diretrizes em razão da dificuldade em replicar a argumentação humana necessária para se proceder a motivações com teor jurídico por envolver valores e normas.

Published: June 2018

O bruxismo é definido como uma atividade repetitiva dos músculos mastigatórios caracterizada pelo ranger e/ou apertar de dentes com diferentes manifestações circadianas. Devido à complexidade da condição e a variedade de distúrbios associados ressalta-se a necessidade de um conhecimento detalhado sobre possíveis fatores individuais a fim de direcionar a conduta específica para consequências do bruxismo. A obtenção de dados genético-moleculares para estudo da possível relação entre genética e bruxismo acarretaria em um melhor diagnóstico e tratamento dos bruxômanos. Dessa forma, o presente estudo buscou elucidar essa relação por meio de uma revisão de literatura. Estudos atuais mostraram indícios da influência de genes da via dopaminérgica e seratoninérgica no desenvolvimento do bruxismo. Com base em relações que possam existir entre fatores genéticos e a origem da condição, mostra-se necessária a ampliação do campo de pesquisa genética-molecular no objetivo de elucidar mecanismos associados e/ou desencadeantes da parafunção, possibilitando diagnósticos e tratamentos precisos.

Entre o co-rrupto e o co-rreto. Leitura de marcos 10, 35-45
Authors: Míguez Néstor
Published: June 2018

Este artigo explora a relação entre o correto e o corrupto nas relações de poder. Ele parte da análise da resposta de Jesus aos filhos de Zebedeu, quando eles pedem lugares de privilégio no Reino, uma resposta com a qual Jesus faz um contraste entre o poder dos governantes e o poder do serviço. Destaca a diferença entre “poder” como um substantivo e “poder” como um verbo. Em seguida, considera-se as aporias entre o correto e o corrupto no uso do poder na micro e macro política e na esfera das relações sociais e culturais.
Conflito e poder na história de José (Gen 37-50): Gênises 47, 13-26 e a crítica a um projeto de dominação
Authors: Castillo David
Published: June 2018

Este artigo explora a recepção interpretativa da história de José (Gênesis 37-50), coletando as posições diferentes em torno da leitura do personagem principal e discurso central desta tradição, a qual tem sido entendida por uma linha de crítica bíblica como argumento legitimador de um poder monárquico. A partir desta revisita se destaca o vazio em torno da análise de Gênesis 47, 13-26, para propor que o resgate dessa história perigosa permite não só uma leitura mais complexa e ideologicamente conflitiva de José e sua história, mas também uma crítica dos sistemas teológicos e econômicos que promovem a escravidão e a opressão do povo.
A omissão de Séforis: uma estratégia de resistência contra o poder e a honra da Dinastia Herodiana
Authors: Winedt Marlon
Published: June 2018

Séforis, cidade majestosa, construída pelo rei-cliente de Roma, Herodes Antipas, não aparece nos anais da igreja primitiva. Não aparece nos quatro evangelhos, nem nos atos dos Apóstolos, nem em outros escritos da coleção canônica. Séforis era uma continuação dos grandes projectos de construção de Herodes o grande, seu pai. Se localizarmos as construções herodianas dentro do paradigma sócio-cultural de honra-vergonha, do mundo greco-romano e culturas mediterrâneas, podemos ver que espaços públicos assumem importância na identidade coletiva dos povos, como uma expressão material e palpável de honra da elite. A omissão desta cidade, a 5 km da Nazaré, nos quatro Evangelhos e em todas as fontes orais e escritas, indica que a igreja primitiva continuou a atitude profética e desafiadora de Jesus frente ao poder herodiano. Ignorar uma cidade judaica como Séforis, embora com forte influência greco-romana, era ignorar um símbolo importante do poder e fama herodiana. Equivalia a censurar com dureza a dinastia idumea-judía, e ao mesmo tempo denunciar o abuso de poder.

2018! Transcorridos quase 18 anos do 21º milênio, desigualdades de gênero persistem, exigindo que as lutas continuem, quer no âmbito secular, quer no contexto de diferentes religiões. Lutas, no plural, porque são muitas as frentes, grupos e atorxs que aí se engajam, embora com muitos objetivos em comum. Os artigos deste número da Mandrágora dão evidência da necessidade de avançar ao apontar as assimetrias e lacunas. A começar por aquelas presentes nos próprios Programas de Pós-Graduação em Ciências da Religião no Brasil, a um dos quais está vinculada esta revista, e mesmo nas pesquisas em perspectiva feminista e de gênero produzidas no contexto desses programas, conforme pode-se verificar na detalhada investigação de Clóvis Ecco, Thaís Alves Marinho e Claudete Ribeiro de Araújo, no artigo intitulado “Religião e gênero: uma investigação do estado da arte dos estudos de gênero nos programas de pós-graduação em ciências da religião no Brasil”. Efetuando o mapeamento das dissertações e teses que têm trabalhado questões relativas às desigualdades de gênero (estado da arte), os/as autores/as analisam como as Ciências da Religião no Brasil têm absorvido as principais discussões acerca da categoria nos últimos 17 anos. Na sua análise contemplam também o levantamento dos números de homens e mulheres que compõem o quadro de docentes, discentes e funcionários dos Programas de Pós-Graduação em Ciências da Religião.

Maria: ícone para o qual converge e do qual emerge um feixe de significados de diferentes aspectos da cultura
Authors: Lemos Carolina Teles
Published: June 2018

ResumoNo campo religioso, mais especificamente nas crenças e práticas presentes na tradição católica, a presença de Maria é uma constante que se manifesta de várias maneiras. No entanto, quando se refere à Maria, é difícil saber de qual espaço religioso estamos falando. Se a religião contém e expressa o ethos de uma população, como afirma Geertz, que aspectos de nosso ethos as devoções a Maria estão expressando? Este artigo visa analisar os significados conferidos à Maria, à luz dessas questões. Trata-se de uma pesquisa bibliográfica, com algumas incursões em dados empíricos. Entende-se que a tradição judaico-cristã percorreu um longo caminho no processo de significação à Maria, centralizando tais significados na maternidade, articulando-a a uma visão restritiva da sexualidade feminina.

Growth and Yield Responses of Cucumber (Cucumis sativum L.) to Different Nitrogen Levels of Goat Manure in the Humid Ultisols Environment
Authors: LAW-OGBOMO Kolawole Edomwonyi , OSAIGBOVO Agbonsalo Ulamen
Published: June 2018

A field trial was conducted at the Experimental Farm of the University of Benin, Benin City, Nigeria between May and July in both 2015 and 2016 to evaluate growth and yield responses of cucumber (Cucumis sativum L.) to different nitrogen levels of goat manure. The experiment was laid out in a randomized complete block design involving five treatments and replicated three times. The treatments were cured goat manure applied at levels of 0, 100, 200, 300 and 400 kg N ha-1. Growth parameters were collected on vine length (cm), vine girth (cm), number of branches, number of leaves and leaf area index (LAI). Yield parameters assessed were fruit length (cm), fruit girth (cm), number of fruits per plant and fruit yield (t ha-1). Goat manure application significantly (P < 0.05) influenced growth parameters positively, which led to the enhancement of the fruit yield. Goat manure application levels of 200 (20.85 t ha-1), 300 (20.85 t ha-1) and 400 (26.21 t ha-1) kg N ha-1 had similar (P > 0.05) fruit yield, but significantly (P < 0.05) higher than those of 0 (12.34 t ha-1) and 10 (16.96 t ha-1) kg N ha-1. It thus recommended that goat manure at 20 kg N ha-1 is more appropriate for cucumber production in the humid ultisols environment.

Twenty eight (28) Bambara groundnut accessions were planted in a randomized complete block design with two treatments (Non-water stressed and Water stressed) and replicated five times. The experiment was conducted at the Experimental Garden of the Department of Biological Sciences, Federal University of Technology, Minna, Niger State. The accessions were planted in planting bags during the cropping season of 2016 between July and October. The two treatments were rain fed until maturity except during the period of exposure to water stress where the water stressed plants were transferred to a screen house made with polyvinyl ceiling to prevent water during the flowering stage for two weeks. It was observed that water stress reduced the yield of the Bambara groundnut landraces by 47%. Accessions NGB-01646-B, NGR-NI-20-H  and NGB-01491 which had relatively high yield in the stressed and non- water stressed condition were considered  the most drought tolerant accessions and accession NGR-KG-02-C with low yield both in stressed and non-stressed conditions was identified as the most susceptible accession. Accessions which had high yield only in water stressed conditions could serve as elite line for Bambara groundnut for areas which have problem of drought. These drought tolerant accessions identified in the research can serve as potential parent lines in breeding programmes aimed at the development of drought tolerant varieties of Bambara groundnut.

The incidence of airborne pollen occurring as aeroallergens of varied levels at different periods of the year has generated some public health concern globally. The present study was conducted in order to examine the monthly depositional rate of airborne pollen and fern spores, as well as the impact of meteorological parameters and local plants on pollen distribution at two study sites in Kaduna and Sokoto States of North Western Nigeria. The study spanned a period of one year, during which a modified Tauber pollen sampler was employed in the collection of atmospheric pollen and fern spores; local plants were also enumerated. Residual solution was collected monthly, subjected to acetolysis and the treated residues were viewed for microscopic studies. The results reveal monthly distribution of airborne pollen and fern spore types at the study sites during the sampling period. Dominant pollen types in Kaduna State were those of Alchornea laxiflora, Pinus caribaea, Terminalia sp., Sapotaceae and Poaceae family. Pollen of Syzygium guineense, Alchornea sp., Sapotaceae and Poaceae dominated in Sokoto State. Spores of Pteris sp., Nephrolepis sp. and a trilete fern were also recovered at both locations. Some local plants in the immediate vegetation contributed to the aeroflora of these locations. No significant correlation was recorded between monthly total pollen concentrations and mean monthly meteorological parameters of the locations. It is imperative to investigate the allergenicity of these dominant pollen types, so as to aid pollen hypersensitive individuals in adopting appropriate prophylactic measures.
Modelling microstructural changes of ordinary Portland cement paste at elevated temperature
Authors: Zhang Qi , Ye Guang
Published: June 2018

On the material level, the deterioration of ordinary Portland cement (OPC) paste at elevated temperature is attributed to chemical transitions and microstructural cracking. However, few studies on the quantitative characterisation of the degradation process of OPC paste have been reported and thus the quantitative relationship between microcracking and strength loss of OPC paste remains unclear. A simulation procedure for modelling the microstructural changes of OPC paste at elevated temperature was developed in this work. After the microstructural simulation, a virtual tensile test was performed on fire-damaged microstructures in order to evaluate the tensile strength and Young's modulus. The strength losses of OPC paste due to both chemical transitions and microcracking were then quantified.

Authors: Bawa Shailja , Singh Surinder Pal
Published: June 2018

This paper presents the results of an investigation conducted to analyse the flexural fatigue life of self-compacting concrete with different proportions of steel fibre (SF) and polypropylene fibre (PPF) reinforcement. An experimental programme was planned to obtain the fatigue lives of approximately 250 beam specimens under four-point flexural loading. Approximately 90 static flexural strength tests were also conducted to facilitate fatigue testing. The proportions of SF and PPF varied in volume but the total volume was kept at 1%. The two-parameter Weibull distribution was used to describe the probability distributions of fatigue life data at different stress levels. The gradual replacement of SF with PPF in the mixes was found to reduce the variability in the distribution of fatigue life significantly. The maximum increase of 62% in the shape parameter for the fatigue life of a mix with 100% PPF as with a mix containing 100% SF was observed at a stress level of 0·85.
Treatment of bentonite fluid for excavation into Chalk

This paper is concerned with the treatment of a bentonite support fluid during excavations extending into Chalk. Chalk can disintegrate during the excavation process and can, like any other soil that may disperse into the slurry, significantly alter the properties of the fluid if it is not appropriately managed. A case history in Woolwich, East London is presented to highlight the necessity for treatment of the bentonite slurry used to support grounds that release fines. It was found that, with use of the solids-separation equipment, the slurry could be maintained within specification over the course of the project. Desanders, desilters and a centrifuge were necessary for slurry management during the works. At the end of the works, the centrifuge was used to separate the unwanted residual slurry into a paste and a centrate of near-clear water. Chemical analyses conducted on the centrate confirmed that it was comfortably within specification for disposal to a foul sewer and physical tests on the dewatered bentonite sludge confirmed that it was sufficiently stiff that it could be disposed as a solid waste along with other soil arisings. The centrifuge treatment thus eliminated the high costs of transport and disposal of unwanted bentonite slurry.
One-dimensional non-linear consolidation theory of soft ground coupled with thermal effect
Authors: Quan Liu , Deng YueBao , Chen Fei
Published: June 2018

Temperature has an important effect on the consolidation of soft soil. Considering current experimental data, a compression model for soft soil considering the influence of temperature is discussed. At the same time, a new expression for the permeability of soft soil considering the effect of temperature is presented. On the basis of the two models, a one-dimensional non-linear consolidation equation considering the effect of temperature on soft ground is established. Following the classical solution method of Davis and Raymond, the equation is solved analytically. After that, the influence of temperature on the consolidation process of soft ground is analysed. The results show that the higher the temperature, the faster will be the consolidation rate; the influence of temperature on consolidation rate is not a simple linear relationship.

Published: June 2018

Rapid impact compaction (RIC) has been used effectively as a ground improvement at medium depth technique for granular soils. RIC is normally used to increase bearing capacity, reduce potential settlements and mitigate liquefaction. This paper presents a calibrated three-dimensional cap-plasticity finite-element model (FEM) to simulate ground improvement using RIC. The results of 107 RIC field compaction points were used to calibrate and validate the FEM. Numerical outcomes of the FEM showed good agreement with the field compaction results. The FEM was further used to propose a relationship between the soil bearing capacity and the number of hammer blows for engineering practice. This is attained by performing pushover analysis of a spread footing resting on RIC improved soils with different numbers of RIC blows. The RIC, circular 1·5 m anvil was used as the spread footing. The applied stresses that produced 25 mm settlement are considered the improved soil bearing capacity. Also, the paper presents a recommendation for the optimum number of blows after which more blows will have no significance.

Published: June 2018

An experimental investigation on eccentrically loaded stainless steel tubular columns filled with steel-fibre-reinforced concrete (SFRC) is presented in this paper. The composite columns had different depth-to-plate thickness (D/t) ratios, stainless steel tube cross-sections, lengths, non-dimensional slenderness, concrete strengths, steel fibre percentages and concrete type. The pin-ended composite columns were subjected to eccentric compressive loads with a large eccentricity of 0·25D. The composite column strengths, load–axial shortening behaviour and failure modes were measured and observed in the tests. The experimental investigation showed that eccentrically loaded SFRC-filled stainless steel tubular columns offer a considerable enhancement in column strength compared with those filled with plain concrete (PC). In addition, it was found that an increase in the steel fibre percentage enhanced the strength behaviour of the composite columns. Furthermore, the composite column test strengths were compared with design strengths predicted using Eurocode 4 for composite columns. Generally, the investigation showed that the code accurately predicted the strengths of the eccentrically loaded PC-filled stainless steel tubular columns of high concrete strength and was quite conservative in estimating the column strengths of the eccentrically loaded SFRC-filled stainless steel tubular columns.

Background

X-linked Alport syndrome (XLAS) is a progressive hereditary nephropathy caused by mutations in the COL4A5 gene. Genotype-phenotype correlation in male XLAS is relatively well established; relative to truncating mutations, nontruncating mutations exhibit milder phenotypes. However, transcript comparison between XLAS cases with splicing abnormalities that result in a premature stop codon and those with nontruncating splicing abnormalities has not been reported, mainly because transcript analysis is not routinely conducted in patients with XLAS.

Methods

We examined transcript expression for all patients with suspected splicing abnormalities who were treated at one hospital between January of 2006 and July of 2017. Additionally, we recruited 46 males from 29 families with splicing abnormalities to examine genotype-phenotype correlation in patients with truncating (n=21, from 14 families) and nontruncating (n=25, from 15 families) mutations at the transcript level.

Results

We detected 41 XLAS families with abnormal splicing patterns and described novel XLAS atypical splicing patterns (n=14) other than exon skipping caused by point mutations in the splice consensus sequence. The median age for developing ESRD was 20 years (95% confidence interval, 14 to 23 years) among patients with truncating mutations and 29 years (95% confidence interval, 25 to 40 years) among patients with nontruncating mutations (P=0.001).

Conclusions

We report unpredictable atypical splicing in the COL4A5 gene in male patients with XLAS and reveal that renal prognosis differs significantly for patients with truncating versus nontruncating splicing abnormalities. Our results suggest that splicing modulation should be explored as a therapy for XLAS with truncating mutations.
