Wyprawa Cyrusa i odwrót Dziesięciu Tysięcy w przekazie Diodora (14.19–31; 37.1–4): Przekład i komentarz
Authors: Głogowski Piotr
Published: August 2018

The author presents the first Polish translation of the section of the work by Diodorus Siculus devoted to the expedition of Cyrus the Younger and the Retreat of the Ten Thousand (Diod. 14.19–31; 37.1–4). The translation is supplemented by the commentary, which focuses mainly on the problem of the sources exploited by the direct source of Diodorus in this part of his work – Ephorus of Cyme. Therefore, the basic aim of the commentary is to display the similarities and differences between the narrative of Diodorus and the Anabasis of Xenophon and other sources, e.g. Persica by Ctesias of Cnidus.

Latin as a cultural Identity: a central European Case.
Authors: Bering Piotr
Published: August 2018

Central Europe entered in the sphere of Christian and Latin Civilization later than the Western part of the continent. As a result, the new members of this community had to import most of their ‘cultural goods’, but the imports were in a relatively short time recognized as their ‘own’. This general process can be testified to by the stage plays. The use of Latin lasted in Central Europe much longer than in Western Europe and coexistedwith the native languages, including in the theatrical output. The theatrical output is significant in this respect as it presents, among other sources, the mutual relationship that existed between Latin and the native language.

Published: August 2018

Ancient DNA was analyzed in altogether 28 Late Eneolithic and Bronze Age human skeletons form 4 sites in southern Ukraine. More than 0,3% of human DNA was preserved only in 13 skeletons. The results of our analyses provide evidence that recovery of DNA molecules suitable for genetic analyses is more dependent on the specificity of the archaeological site and is not strongly correlated with particular environmental factors.

Published: August 2018

The paper presents δ13C and δ15N isotope content measurements in human bones from 16 graves, being part of the Yampil Barrow Complex. From the results, conclusions may be drawn about the diet of barrow builders and users. It was based on vegetable foodstuffs and characterised by a varied share of terrestrial animal meat, depending on the period. High δ13C values suggest a share of C4-type plants in the diet, possibly millet.

A Novel Non-Linear Control for Three-Phase Five-Level Cascaded H-Bridge Inverter Based Shunt Active Power Filter
Authors: Ray Soumyadeep , Gupta Nitin , Gupta Ram Avtar
Published: August 2018

Cascaded H-Bridge multilevel inverter (CHB-MLI) based shunt active power filter (SAPF) provides a cost-worthy and realistic solution for mitigating current related power quality problems in case of medium-voltage and high-power grid. Mitigation of current harmonic component, reactive power minimization and power factor correction depend on accuracy of control technique applied to the CHB-MLI based SAPF unit. Switching technique dynamics is not considered by most of the researchers while designing control techniques applied to SAPF unit and hence it is assumed linear in order to make system simpler. A limited amount of literature is available which considers the non-linearity of CHB-MLI switching pattern while designing control theory for MLI based SAPF. Therefore, a novel non-linear control is proposed in this paper to enhance system steady-state and dynamic performance. This non-linear control is based on dynamic mathematical modeling of five-level CHB-MLI tied SAPF. Stability of proposed control strategy applied to CHB-MLI based SAPF is rigorously checked by using Lyapunov’s direct method. Proportional-Integral controller is used for stabilizing DC-link voltages to its proper reference value. This proposed control exhibits excellent dynamic performance and compensation criteria in comparison to conventional control techniques available in the literature. The effectiveness of the proposed control theory is tested rigorously in MATLAB/Simulink and verified through hardware prototype under steady-state and transient operating conditions. Rigorous analysis from hardware and simulation results confirms that source current waveform is in compliance with IEEE-519 standard defined THD limit.
Saving Behavior and Housing Wealth Evidence from German Micro Data
Authors: Gröbel Sören , Ihle Dorothee
Published: August 2018

Housing property is the most important position in a household’s wealth portfolio. Even though there is strong evidence that house price cycles and saving patterns behave synchronously, the underlying causes remain controversial. The present paper examines if there is a wealth effect of house prices on savings using household-level panel data from the German Socio-Economic Panel for the period 1996-2012. We find that young homeowners decrease their savings in response to unanticipated house price shocks, whereas old households hardly respond to house price changes. Although effects are relatively low in magnitude, we interpret this as evidence of a housing wealth effect.
Waiting Times for Outpatient Treatment in Germany: New Experimental Evidence from Primary Data
Authors: Heinrich Nils , Wübker Ansgar , Wuckel Christiane
Published: August 2018

Long waiting times are a common feature and a major concern in many public health care systems. They are often characterized as inefficient because they are a burden to patients without generating any gains for providers. There is an ongoing debate in Germany regarding the preferential treatment given to private health insurance (PHI) holders while statutory health insurance (SHI) holders face continuously increasing waiting times. In order to tackle this problem in the outpatient sector, Germany initiated a reform in 2015 which was aimed at providing SHI holders with appointments within an acceptable time frame. We exploit longitudinal experimental data to examine waiting times for six elective outpatient treatments in Germany for PHI and SHI holders before and after the reform. We find a considerable difference in waiting times favoring private patients. For SHI holders, waiting times remained stable over time (27.5 days in 2014, 30.7 days in 2016, Δ 3.2 days, p-value=0.889) while PHI holders experienced a significant improvement (13.5 days in 2014; 7.8 days in 2016; Δ 5.7 days, p-value=0.002). The results indicate that even after the reform there is still an unequal access to elective outpatient treatment depending on the patient’s insurance status.
Does Obesity Shorten Life? Or is it the Soda? On Non-manipulable Causes
Authors: Pearl Judea
Published: August 2018

Non-manipulable factors, such as gender or race have posed conceptual and practical challenges to causal analysts. On the one hand these factors do have consequences, and on the other hand, they do not fit into the experimentalist conception of causation. This paper addresses this challenge in the context of public debates over the health cost of obesity, and offers a new perspective, based on the theory of Structural Causal Models (SCM).

Staunton, CA, Stanger, JJ, Wundersitz, DW, Gordon, BA, Custovic, E, and Kingsley, MI. Criterion validity of a MARG sensor to assess countermovement jump performance in elite basketballers. J Strength Cond Res 35(3): 797–803, 2021—This study assessed the criterion validity of a magnetic, angular rate, and gravity (MARG) sensor to measure countermovement jump (CMJ) performance metrics, including CMJ kinetics before take-off, in elite basketballers. Fifty-four basketballers performed 2 CMJs on a force platform with data simultaneously recorded by a MARG sensor located centrally on the player's back. Vertical accelerations recorded from the MARG sensor were expressed relative to the direction of gravity. Jumps were analyzed by a blinded assessor and the best jump according to the force platform was used for comparison. Pearson correlation coefficients (r) and mean bias with 95% ratio limits of agreement (95% RLOA) were calculated between the MARG sensor and the force platform for jumps performed with correct technique (n = 44). The mean bias for all CMJ metrics was less than 3%. Ninety-five percent RLOA between MARG- and force platform–derived flight time and jump height were 1 ± 7% and 1 ± 15%, respectively. For CMJ performance metrics before takeoff, impulse displayed less random error (95% RLOA: 1 ± 13%) when compared with mean concentric power and time to maximum force displayed (95% RLOA: 0 ± 29% and 1 ± 34%, respectively). Correlations between MARG and force platform were significant for all CMJ metrics and ranged from large for jump height (r = 0.65) to nearly perfect for mean concentric power (r = 0.95). Strong relationships, low mean bias, and low random error between MARG and force platform suggest that MARG sensors can provide a practical and inexpensive tool to measure impulse and flight time–derived CMJ performance metrics.
Experimental Traumatic Brain Injury Identifies Distinct Early and Late Phase Axonal Conduction Deficits of White Matter Pathophysiology, and Reveals Intervening Recovery
Authors: Marion Christina M. , Radomski Kryslaine L. , Cramer Nathan P. , Galdzicki Zygmunt , Armstrong Regina C.
Published: August 2018

Traumatic brain injury (TBI) patients often exhibit slowed information processing speed that can underlie diverse symptoms. Processing speed depends on neural circuit function at synapses, in the soma, and along axons. Long axons in white matter (WM) tracts are particularly vulnerable to TBI. We hypothesized that disrupted axon–myelin interactions that slow or block action potential conduction in WM tracts may contribute to slowed processing speed after TBI. Concussive TBI in male/female mice was used to produce traumatic axonal injury in the corpus callosum (CC), similar to WM pathology in human TBI cases. Compound action potential velocity was slowed along myelinated axons at 3 d after TBI with partial recovery by 2 weeks, suggesting early demyelination followed by remyelination. Ultrastructurally, dispersed demyelinated axons and disorganized myelin attachment to axons at paranodes were apparent within CC regions exhibiting traumatic axonal injury. Action potential conduction is exquisitely sensitive to paranode abnormalities. Molecular identification of paranodes and nodes of Ranvier detected asymmetrical paranode pairs and abnormal heminodes after TBI. Fluorescent labeling of oligodendrocyte progenitors inNG2CreER;mTmGmice showed increased synthesis of new membranes extended along axons to paranodes, indicating remyelination after TBI. At later times after TBI, an overall loss of conducting axons was observed at 6 weeks followed by CC atrophy at 8 weeks. These studies identify a progression of both myelinated axon conduction deficits and axon–myelin pathology in the CC, implicating WM injury in impaired information processing at early and late phases after TBI. Furthermore, the intervening recovery reveals a potential therapeutic window.

SIGNIFICANCE STATEMENTTraumatic brain injury (TBI) is a major global health concern. Across the spectrum of TBI severities, impaired information processing can contribute to diverse functional deficits that underlie persistent symptoms. We used experimental TBI to exploit technical advantages in mice while modeling traumatic axonal injury in white matter tracts, which is a key pathological feature of human TBI. A combination of approaches revealed slowed and failed signal conduction along with damage to the structure and molecular composition of myelinated axons in the white matter after TBI. An early regenerative response was not sustained yet reveals a potential time window for intervention. These insights into white matter abnormalities underlying axon conduction deficits can inform strategies to improve treatment options for TBI patients.

Published: August 2018

Using region-specific injection of hyaluronic acid, we developed a mouse model of acute retinal detachment (RD) to investigate molecular mechanisms of photoreceptor cell death triggered by RD. We focused on the transient receptor potential vanilloid 4 (TRPV4) ion channel, which functions as a thermosensor, osmosensor, and/or mechanosensor. After RD, the number of apoptotic photoreceptors was reduced by ∼50% in TRPV4KO mice relative to wild-type mice, indicating the possible involvement of TRPV4 activation in RD-induced photoreceptor cell death. Furthermore, TRPV4 expressed in Müller glial cells can be activated by mechanical stimuli caused by RD-induced swelling of these cells, resulting in release of the cytokine MCP-1, which is reported as a mediator of Müller glia-derived strong mediator for RD-induced photoreceptor death. We also found that the TRPV4 activation by the Müller glial swelling was potentiated by body temperature. Together, our results suggest that RD adversely impacts photoreceptor viability via TRPV4-dependent cytokine release from Müller glial cells and that TRPV4 is part of a novel molecular pathway that could exacerbate the effects of hypoxia on photoreceptor survival after RD.

SIGNIFICANCE STATEMENTIdentification of the mechanisms of photoreceptor death in retinal detachment is required for establishment of therapeutic targets for preventing loss of visual acuity. In this study, we found that TRPV4 expressed in Müller glial cells can be activated by mechanical stimuli caused by RD-induced swelling of these cells, resulting in release of the cytokine MCP-1, which is reported as a mediator of Müller glia-derived strong mediator for RD-induced photoreceptor death. We also found that the TRPV4 activation by the Müller glial swelling was potentiated by body temperature. Hence, TRPV4 inhibition could suppress cell death in RD pathological conditions and suggests that TRPV4 in Müller glial cells might be a novel therapeutic target for preventing photoreceptor cell death after RD.
No link between season of birth and subsequent development of Graves’ disease or toxic nodular goitre. A nationwide Danish register-based study
Authors: Sivalingam Suvanjaa , Thvilum Marianne , Brix Thomas Heiberg , Hegedüs Laszlo , Brandt Frans
Published: August 2018

Background

Season of birth, an exogenous indicator of early life environment, has been linked with a higher risk of adverse health outcomes such as autoimmune thyroiditis, multiple sclerosis and schizophrenia later in life. Whether the development and cause of hyperthyroidism is influenced by season of birth is unclarified. We aimed, at a nationwide level, to investigate whether season of birth influences the risk of hyperthyroidism due to Graves’ disease (GD) and/or toxic nodular goitre (TNG).

Method

Register-based nationwide cohort study. By record-linkage between Danish health registers, 36,087 and 20,537 patients with GD and TNG, respectively, were identified. Each case was matched with four controls without thyroid disease, according to age and sex. Differences in month of birth across the year were evaluated by the Walter–Elwood test. Hazard ratios, for the risk of GD and TNG in individuals born in a certain month or season of the year, were calculated using Cox regression models.

Results

Neither for GD nor for TNG could we demonstrate a significant difference in birth rate across months or seasons of the year (Walter–Elwood’s test; X2 = 5.92 and X2 = 1.27, P = 0.052 and P = 0.53, respectively).

Conclusion

Irrespective of its cause, our findings do not support the hypothesis that season of birth is significantly related to the development of hyperthyroidism.
IUGR impairs cardiomyocyte growth and maturation in fetal sheep
Authors: Jonker Sonnet S , Kamna Daniel , LoTurco Dan , Kailey Jenai , Brown Laura D
Published: August 2018

Placental insufficiency causes intrauterine growth restriction (IUGR), a common complication of pregnancy. In skeletal muscle, IUGR reduces fetal myofibril size, reduces myoblast proliferation and reduces expression of genes in cell cycle regulation clusters. The myocardium is striated like skeletal muscle, and IUGR also reduces cell cycle activity and maturation in cardiomyocytes, despite cardiac output preferentially directed to the coronary circulation. We hypothesized that cardiomyocyte growth restriction would be accompanied by similar changes in cell cycle regulation genes and would reduce cardiomyocyte cell cycle activity, number, maturity and size. Pregnant ewes were housed in elevated ambient temperatures from ~40 to ~115 days of gestation (dGA) to produce placental insufficiency and IUGR; fetal hearts were studied at ~134 dGA. Hearts were biopsied for mRNA analysis and then dissociated into individual myocytes (Controln = 8; IUGRn = 15) or dissected (Controln = 9; IUGRn = 13). IUGR fetuses had low circulating insulin and insulin-like growth factor 1 (IGF1) and high circulating cortisol. Bodies and hearts of IUGR fetuses were lighter than those of Controls. Cardiomyocytes of IUGR fetuses were smaller, less mature, less active in the cell cycle and less numerous than in Controls. Further, there was a pattern of downregulation of cell cycle genes in IUGR ventricles. IUGR growth profiles in heart and skeletal muscle suggest similar regulation despite differences in blood and nutrient delivery prioritization. IGF1 signaling is suggested as a mechanism regulating altered growth in IUGR striated muscle and a potential therapeutic candidate.

Published: August 2018

Introduction: The purpose of this study was to detect ybtS, entB, mrkD, magA, kfu, iutA, rmpA and K2 genes in extended-spectrum beta-lactamase (ESBL) - and non-ESBL producing Klebsiella pneumoniae.

Methods: To this end, 70 K. pneumoniae isolates were selected from hospitals of Kurdistan Province, Iran. The ESBL phenotype was conducted utilizing the disc diffusion technique in accordance with CLSI procedures. Detection of virulence factor genes was performed by the PCR in the ESBL and non-ESBL isolates.

Results: Sixty-two (88.6%) isolates of K. pneumoniae were ESBL producers. Further, entB had the most frequency in all the isolates. There were no significant differences between ESBL production and the presence of ybt S, entB, mrkD, magA, kfu, iutA, rmpA and K2 genes and the presence of these genes and variables such as presence of sex, clinical specimen type, and hvKP phenotype among the ESBL and non-ESBL K. pneumoniae isolates.

Conclusion: In conclusion, in other studies, K. pneumoniae strains were separated from liver abscesses and the magA gene was frequently present; however, in our study, the K. pneumoniae strains were separated from various clinical specimens and the magA gene had low frequency.

Published: August 2018

BACKGROUND:

In moderate acute malnutrition programs, it is common practice to not measure mid-upper arm circumference (MUAC) of children whose length is <67 cm. This is based on expert opinion that supplementation of shorter children with low MUAC and weight-for-height z score ≥−2 may increase risk of excessive fat accumulation. Our aim was to assess if shorter children gain more fat than taller children when treated for moderate acute malnutrition diagnosed by low MUAC alone.

METHODS:

In this observational study, we included children aged 6 to 23 months with a MUAC between 115 and 125 mm and a weight-for-height z score ≥−2. On the basis of length at admission, children were categorized as short if <67 cm and long if ≥67 cm. Linear mixed-effects models were used to assess body composition on the basis of deuterium dilution and skinfold thickness.

RESULTS:

After 12 weeks of supplementation, there was no difference in change in fat mass index (−0.038 kg/m2, 95% confidence interval [CI]: −0.257 to 0.181, P = .74) or fat-free mass index (0.061 kg/m2, 95% CI: −0.150 to 0.271, P = .57) in short versus long. In absolute terms, the short children gained both less fat-free mass (−230 g, 95% CI: −355 to −106, P < .001) and fat mass (−97 g, 95% CI: −205 to 10, P = .076). There was no difference in changes in absolute subscapular and triceps skinfold thickness and z scores (P > .5).

CONCLUSIONS:

Short children with low MUAC do not gain excessive fat during supplementation. With these data, we support a recommendation for policy change to include all children ≥6 months with low MUAC in supplementary feeding programs, regardless of length. The use of length as a criterion for measuring MUAC to determine treatment eligibility should be discontinued in policy and practice.

Published: August 2018

O presente estudo investigou a experiência da paternidade ao final do primeiro ano de vida do bebê. Participaram 35 pais primíparos que eram de níveis socioeconômicos variados e residiam na região metropolitana de Porto Alegre. Os pais foram entrevistados individualmente e suas verbalizações foram analisadas através da análise de conteúdo em três categorias: O pai e a experiência da paternidade, O filho e a experiência da paternidade e A esposa e a experiência da paternidade. Os resultados indicaram que a experiência da paternidade, no final do primeiro ano de vida do bebê, esteve associada a sentimentos de satisfação, sendo que os pais mostraram-se bastante participativos e envolvidos na vida familiar, assim como nos cuidados com o bebê. Todavia, ainda que muitas vezes de forma sutil e contraditória, os participantes expressaram certa ambivalência frente à experiência da paternidade com seu primeiro filho, demandando dos pais um reposicionamento frente à vida.

Published: August 2018

Analysis of the differential item functioning (DIF) is of great importance when developing or validating psychological instruments, since it enables to identify whether there are bias on a given instrument concerning sample characteristics. Considering this importance, in this study, we verified the presence of DIF within items of a new instrument for the measurement of mindfulness (MAP), regarding the sex, age, practice with meditation, and use of alternative medicine of the sample. For this, 788 Brazilian adults, mean age of 26 years (SD=9.59), most women (79%) and single, responded the MAP. Overall, no DIF was identified with the positively worded items, indicating that the analyzed items do not favor, specifically, any of the groups tested in the present study.
Resilience and psychoanalysis: a systematic review

Published: August 2018

The aim of this paper was to investigate the concept of resilience by studying texts published in the field of psychoanalysis (over a ten-year period). Through a systematic review of articles published between 2004 and 2014, using descriptors in Portuguese, Spanish and English. Five data bases were searched, namely Pubmed, Lilacs, Scielo, BVS Index Psi and PsycInfo. We gathered 280 published items, including articles, papers, reviews and other types of material. After exclusion criteria, 11 articles were selected for analysis. The majority of the analysed articles were theoretical reviews. The concept of resilience in Psychoanalysis tends to be related to other concepts (e.g. trauma and violence). By itself it indicates an ability that was built fundamentally in through relationships: between subjects, and between subjects and their environments. The studies agree on the notion of resilience as a process that goes beyond simple adaptation. It is in fact an ability to survive, related to intra-psychic capabilities and early emotional experiences. In this respect, resilience emerges as a characteristic that is closely related to the social context of the subject. In fact, it develops from and within this context.

Published: August 2018

A forma como a criança se relaciona socialmente está ligada à maneira como ela compreende o mundo social e, nesse sentido, busca-se conhecer como as mudanças que ocorrem na compreensão social da criança impactam seu comportamento na relação com outras pessoas. Este estudo teve o objetivo de verificar a existência de correlação entre o desenvolvimento de habilidades sociais e o da teoria da mente em crianças pré-escolares. Participaram da pesquisa 30 crianças de 5 anos de idade e suas professoras. Para a avaliação da teoria da mente foi utilizada a Escala de Tarefas, e para a avaliação das habilidades socais foi usado o Questionário de Comportamentos Socialmente Adequados, na sua versão para professores. Os resultados não mostraram associação entre as variáveis, sugerindo que a teoria da mente pode estar ligada a comportamentos sociais sem se expressar ou estar diretamente relacionada a um conjunto de habilidades sociais positivas.

This paper has focused on analyzing morphological change features of Nha Trang Beach based on the comparison of different beach profiles which were measured from July 2008 to September 2016 corresponding to the Northeast and Southwest monsoons. Additionally, the sediment transport balance was estimated by the method of equity value curve. Studied results show that the beach profiles were accreted and eroded during Southwest and Northeast monsoons respectively, but due to the shortage of materials supply, the beach has the narrowing trend. In this paper, some effects of the existing works in Nha Trang Beach such as Vinpearl, Navy Port, and hydro-dams in upstream area of Cai river have been also analyzed for estimating sedimentary supply to beach segments.

The study was conducted at three sites representing large variation in gradient of salinity from very low (Thanh Ha) to medium (Cam Nam) and high (Cam Thanh) in rainy (12/2015) and dry seasons (6/2016) in downstream area of Thu Bon river. At each site, goby species were sampled with traps and measurements of enviromental factors (pH, temperature, salinity, dissolved oxygen) and habitats (cover of freshwater weeds-grass, nypa palm-seagrass, sand-mud, mud-sand) were conducted at the 3 sites mentioned above. A total of 14 species belonging to 2 families Gobiidae (8 species) and Eleotridae (6 species) were recorded in rainy and dry seasons, in which the brackishwater site (Cam Thanh) supported the higher number of species (12 species) compared to the transitional site (Cam Nam: 6 species) and the freshwater site (Thanh Ha: 10 species). Results of annalyzing canonical correspondence between goby communities and the enviromental factors and habitats indicate that the distribution of goby community was mainly influenced by pH, salinity, dissolved oxygen and benthic cover of freshwater seaweeds-grass.

Located near center of the Gulf of Thailand, the Tho Chu island group is approximately far 160 km from Ca Mau southwestwards, and 100 km from Phu Quoc island northwestwards. This group consists of 8 islands, of which the largest Tho Chu island is of 12.15 km2 wide and 167 m high, and composes of clastic sedimentary rocks. Despite the greatest distance from the coast, this coastal island group has the characteristics of geological structure, morphology, spatial structure, area, height, ecological landscape, dynamics and stability of natural processes that create the great value of geo-natural position resources and favorable residential environment. Regarding value of geo-economic position resources, the island group belongs to Phu Quoc district, but it meets the good conditions to become a district-level administrative unit belonging to Kien Giang province. This is a priority site for sea-island economic development, the island group has a great potential to develop the marine economic sectors such as fisheries, natural conservation, tourism and other important services such as oil and gas extraction, navigation and search-rescue at sea. In terms of value of geo-political position resources, this island group includes Hon Nhan islet as the basic point of A1, so has the great value for Vietnam’s sovereignty, sovereign rights and interests in the Gulf of Thailand. Situating in the politically high sensitive region, the island group possesses the high value on the defense, could develop into a firmly military outpost contributing to national defense and security at sea.

Published: August 2018

Ly Son is an island district of Quang Ngai province consisting of two islands: Big island and small island. With an area of about 8.7 km2, big island has 2 aquifers. The unconsolidated formation aquifer (qh) has a narrow distribution in the coastal strip with a small thickness, most of the area of the groundwater is saline, meaningless for water supply. The basaltic eruption formation aquifer (βq) is widely distributed, occupying 85% of the island’s area and has moderate water potential and there is capability for construction of public wellfields with small scale of water supply. Potential for groundwater reserves in the βq aquifer is quite abundant: Exploitation potential reserves is 12,638 m3/day, the exploitable reserve is 5,203 m3/day, the exploited reserve classified as class C1 is 3,531 m3/day, enough to meet the current and future water demand in the island. Groundwater exploitation in the island is mainly spontaneous, leading to the risk of salinity intrusion, contamination. It is necessary to rectify this situation with public exploitation solutions and have solutions to protect and develop water resources in a rational way to ensure sustainable development.

Published: August 2018

Abstract Objective: To identify the professors' ideals and practices of undergraduate nursing education regarding the presence of violence during the teaching-learning process. Methods: Qualitative, descriptive and exploratory research, performed by 19 professors. For the collection of the information it had been used the Creativity and Sensitivity Dynamics. The data had been analyzed establishing its approximation with the referential present in Paulo Freire's works. Results: Violence is, on the theoretical and practical classes, problematized in an elementary way. The professors' actions are influenced by their experiences, however with a superficial critical reflection about practicing. Conclusion: The research reaffirm the need of investments in undergraduate nursing courses, mainly when dealing with issues such as violence, involving dialogue and attitudes based on lovingness enabling affective bonds and encouraging everyone to express themselves.
Performance and economic comparison of PRB types in heterogeneous aquifers
Authors: Elder Carl R , Benson Craig H
Published: August 2018

Performance and cost are compared for horizontal permeable reactive barriers (HPRBs), funnel and gate permeable reactive barriers (FGPRBs) and caisson permeable reactive barriers (CPRBs) in heterogeneous aquifers that achieve the same goal (90% of effluent concentrations below 1% of the source concentration and complete plume capture). Variability in influent and effluent concentrations is compared for each permeable reactive barrier (PRB) with different levels of aquifer heterogeneity. HPRBs have the most variable influent and effluent concentrations because an HPRB does not induce upstream mixing. The PRB provides ‘short circuits’ that connect permeable lenses upstream and downstream, reducing residence time. CPRBs have the least variable influent and effluent concentrations for all levels of heterogeneity because of the flow convergence induced by the funnel and caisson homogenises flow rates and concentrations, resulting in less variability in residence time and effluent concentration. The FGPRB falls between the HPRB and the CPRB, and generally is the most cost effective PRB regardless of heterogeneity. The CPRB provides the most efficient use of reactive media but tends to be costlier than the FGPRB. FGPRBs use reactive media efficiently compared to HPRBs, as significant portions of HPRBs are not active in treatment, particularly in more heterogeneous aquifers.

Published: August 2018

In this paper, a series of consolidated undrained triaxial tests, considering four confining pressures (i.e. 50, 100, 200 and 400 kPa), have been performed to investigate the effects of zeolite on the triaxial behaviour of cemented sands. The cement was added to the sand at 4 and 8% (dry weight). Also, natural zeolite was used as an additive to the mixture, and added at 0 and 30% (optimum) by weight of cement. On the basis of the results, it was indicated that the inclusion of zeolite led to increasing the shear strength and peak axial stress. Moreover, the elastic modulus of specimens increased by increasing the cement content as well as the addition of zeolite. Finally, it has been shown that the initial stiffness and peak strength improved by increasing the cement content.
Shape-dependent calculation of specific surface area of aggregates versus X-ray microtomography

Published: August 2018

The specific surface area (SSA) of constituents in a concrete mixture has a significant effect on its workability in fresh state. Excess layer theories relate the SSA to the flow behaviour of mixtures and can be used as part of an approach to mix design. However, measurement of SSA is complex and includes several issues, and thus is commonly replaced by mathematical estimation of the parameter. The mathematical approximation of surface area is based on the assumption of a spherical shape for the particles, which leads to failure of taking into account the effect of shape and the square–cube law. The article explores the possibility of replacing the assumption of a spherical shape with that of Platonic solids as the representative shape to account for the angularity of aggregates. The calculation was conducted based on information on the particle size distribution (PSD) obtained from dry sieving method. A calculated surface area on the assumption of a dodecahedron shape for natural aggregates and a cubical shape for crushed aggregates showed good agreement with SSA measurements conducted by X-ray microtomography. Furthermore, the effect of changes in PSD on the accuracy of the approach was also studied. It was found that the estimated value of SSA was improved in comparison with the traditional way of calculation on the assumption of a spherical shape.
Offshore monopile in the southern North Sea: part II, simulated hydrodynamics and loading

Published: August 2018

This paper considers two methods for determining the local wave particle kinematics and hydrodynamic forces on an idealised wind turbine monopile in the southern North Sea using sea-state data from Teesside Offshore Wind Farm. An assessment of local flow hydrodynamics is important with regard to safe access of personnel from a crew transfer vessel to a monopile. The hydrodynamic behaviour was calculated using an analytical solution from linear diffraction theory and numerical predictions using OpenFoam, with both slip and no-slip cylinder boundary conditions. Provided the underlying sea state is unidirectional, it was found that close agreement is obtained between analytical and numerical spectra derived from the time series of local free surface elevation, water particle velocity components and in-line wave force loading on the monopile. Less satisfactory agreement is achieved with sea states possessing a bimodal spectrum, which suggests that bimodal spectra may not be unidirectional.

Published: August 2018

This paper explores evidence that entrepreneurial opportunities for migrants and other lower-income populations can be expanded in part through increasing the presence of fine-grained scales of plots and plates along main streets, as part of a systematic urban design strategy. It describes that systematic strategy herein. The paper encompasses the study of three main streets with varying plot sizes in the inner city of Stockholm, Sweden, and examines the outcomes for different types and scales of businesses. After presenting the findings, analysis and conclusions, larger questions of urban design for more inclusive economies are discussed.
How inclusive is the sharing economy? And what is the implication for neighbourhood design?
Authors: Zhang Ye , Chen Kenny Han Teng
Published: August 2018

The sharing economy is growing rapidly and in the meantime scepticism emerges questioning its alleged benefits with respect to inclusiveness, such as providing equal access, encouraging participation and building social connection. However, how inclusive the sharing economy is has yet to be adequately explicated. This paper examines the inclusiveness of the sharing economy using a conceptual framework of inclusive economy, highlighting potential risks and problems. It then proposes a model of a more inclusive sharing economy that comprises hybrid sharing platforms and integrates collaborative consumption and co-production in a local community. Following this, the model is translated into a neighbourhood prototype and then tested using a hypothetical urban design scheme for an ordinary neighbourhood in Singapore.
Sidewall shear stress distribution effects on cohesive bank erosion in curved channels

Published: August 2018

A series of experiments were conducted to reveal the effects of the sidewall shear stress distribution (SSSD) on homogeneous cohesive bank erosion processes in a U-shaped flume. The three-dimensional flow velocities were measured in detail and the turbulent kinetic energy method was employed to estimate the SSSD. The experimental results showed that the SSSD changed with the discharge and the point of the maximum shear stress varied within a range of 0·15–0·75 of the relative water depth. The variation of underwater bank topography was found to be consistent with the SSSD and the location of the maximum erosion point was not at the bank toe. The dominant failure mechanisms were observed to be tensile and toppling failures. Furthermore, a simplified bank erosion model (SBEM) was developed with consideration of the SSSD. Compared with the bank stability and toe erosion model, the SBEM can provide a more accurate simulation of bank erosion processes. This study is expected to enrich general understanding of cohesive bank erosion processes in curved channels, which will help to formulate effective strategies for river regulation.
