Stability of twin circular tunnels in cohesive-frictional soil using the node-based smoothed finite element method (NS-FEM)
Authors: Vo Thien M. , Nguyen Tam M. , Chau An N. , Nguyen Hoang C.
Published: February 2017

This paper presents an upper bound limit analysis procedure using the node-based smoothed finite element method (NS-FEM) and second order cone programming (SOCP) to evaluate the stability of twin circular tunnels in cohesive-frictional soils subjected to surcharge loading. At first stage, kinematically admissible displacement fields of the tunnel problems are approximated by NS-FEM using triangular elements (NS-FEM-T3). Next, commercial software Mosek is employed to deal with the optimization problems, which are formulated as second order cone. Collapse loads as well as failure mechanisms of plane strain tunnels are obtained directly by solving the optimization problems. For twin circular tunnels, the distance between centers of two parallel tunnels is the major parameter used to determine the stability. In this study, the effects of mechanical soil properties and the ratio of tunnel diameter and the depth to the tunnel stability are investigated. Numerical results are verified with those available to demonstrate the accuracy of the proposed method.

Published: February 2017

China is located between the Pacific Ocean seismic belt and the Eurasian seismic belt where the seismic activity is frequent. Bridge plays a key role in transportation lifeline, but its construction and maintenance face potential seismic hazard in China, which may lead to a huge economic loss. This study investigates the dynamic response of bridge abutment to sand-rubber mixtures backfill under seismic loading conditions by finite element method. Sand-rubber mixtures is composed of waste fibers, rubber particles, sand and water with a certain mixing ratio and dry density It has been used as an anti-seismic backfill material for slopes, retaining walls, bridge structures and other geo-structures. A series of numerical simulations was carried out to evaluate the effectiveness of this new material as backfill material for bridge abutment. The seismic performance of bridge abutment with different backfill materials was analyzed with respect to settlements and accelerations of ground, foundation pile and bridge abutment. The results show that the sand-rubber mixture can be used as backfill material, and has a great potential in reducing the settlements and accelerations of ground and foundation pile.
Biologically active ion exchange (BIEX) for NOM removal and membrane fouling prevention
Authors: Schulz M. , Winter J. , Wray H. , Barbeau B. , Bérubé P.
Published: February 2017

The natural organic matter (NOM) removal efficiency and regeneration behavior of ion-exchange filters with promoted biological activity (BIEX) was compared to operation where biological activity was suppressed (i.e. abiotic conditions). The impact of BIEX pre-treatment on fouling in subsequent ultrafiltration was also investigated. Biological operation enhanced NOM removal by approximately 50% due to an additional degradation of smaller humic substances, building blocks and low molecular weight acids. Promotion of biological activity significantly increased the time to breakthrough of the filters and, therefore, is expected to lower the regeneration frequency as well as the amount of regenerate of which to dispose. Pre-treatment using BIEX filters resulted in a significant decrease in total and irreversible fouling during subsequent ultrafiltration. The decrease was attributed to the effective removal of medium and low molecular weight NOM fractions. The results indicate that BIEX filtration is a robust, affordable and easy-to-operate pre-treatment approach to minimize fouling in ultrafiltration systems and enhance the quality of the produced permeate.
Field campaign on sediment transport behaviour in a pressure main from pumping station to wastewater treatment plant in Berlin
Authors: Gunkel M. , Pawlowsky-Reusing E.
Published: February 2017

As part of the project KURAS, the Berliner Wasserbetriebe realized a field campaign in 2015 in order to increase the process knowledge regarding the behaviour of transported sediment in the pressure main leading from the pumpstation to the wastewater treatment plant. The field campaign was conducted because of a lack of knowledge about the general condition of the pressure main due to its bad accessibility and the suspicion of deposits caused by hydraulic underload. The practical evidence of the sediment transport performance of this part of the sewer system, dependent on different load cases, should present a basis for further analysis, for example regarding flushing measures. A positive side-effect of the investigation was the description of the amount of pollutants caused by different weather conditions in combined sewer systems and the alterations of the sewage composition due to biogenic processes during transport. The concept included the parallel sampling of the inflow at the pumpstation and the outflow at the end of the pressure main during different weather conditions. By calculating the inflow to the pressure main, as well as its outflow at different flow conditions, it was possible to draw conclusions in regard to the transport behaviour of sediment and the bioprocesses within an 8.5 km section of the pressure main. The results show clearly that the effects of sedimentation and remobilization depend on the flow conditions. The balance of the total suspended solids (TSS) load during daily variations in dry weather shows that the remobilization effect during the run-off peak is not able to compensate for the period of sedimentation happening during the low flow at night. Based on the data for dry weather, an average of 238 kg of TSS deposits in the pressure main remains per day. The remobilization of sediment occurs only due to the abruptly increased delivery rates caused by precipitation events. These high pollution loads lead to a sudden strain at the wastewater treatment plant. It was found that the sediment transport behaviour is characterized by sedimentation up to a flow velocity of 0.35 m/s, while remobilization effects occur above 0.5 m/s. The assumption of bad sediment transport performance in the pressure main was confirmed. Therefore, the results can be used as a basis for further analysis, for example regarding periodical flushing as a means of cleaning the pressure main. The findings, especially regarding the methods and processes, are transferable and can be applied to other pressure mains in combined sewer systems. Besides the outlined evaluation of the sediment transport behaviour of the pressure main, the collected data were used in the project to calibrate a sewer system model, including a water quality model for the catchment area, and as a contribution towards an early physically based sediment transport modelling in InfoWorks CS.

Published: February 2017

The present study focused on the application of response surface methodology to optimize the fabrication of activated carbon (AC) from sugarcane bagasse for adsorption of Cu2+ ion. The AC was synthesized via chemical activation with ZnCl2 as the activating agent. The central composite design based experiments were performed to assess the individual and interactive effect of influential parameters, including activation temperature, ZnCl2 impregnation ratio and activation time on the AC yield and removal of Cu2+ ion from the aqueous environment. The statistically significant, well-fitting quadratic regression models were successfully developed as confirmed by high F- and low P-values (<0.0001), high correlation coefficients and lack-of-fit tests. Accordingly, the optimum AC yield and removal efficiency of Cu2+ were predicted, respectively, as 48.8% and 92.7% which were approximate to the actual values. By applying the predicted optimal parameters, the AC shows a surprisingly high surface area of around 1,500 m2/g accompanied by large pore volume and narrow micropore size at low fabrication temperature.

Breve análise sobre o instituto desaposentação: direito adquirido ou fator agravante da crise do sistema previdenciário brasileiro?
Authors: Soares Fernanda Heloisa Macedo
Published: February 2017

O instituto desaposentação tem sido tema de grande polêmica no âmbito do Direito Previdenciário, pois apesar de não ser prevista pelo ordenamento jurídico brasileiro, logo não pode ser admitida de forma administrativa, porém o Poder Judiciário compreende sua incidência. Diante disso, o presente trabalho tem como objetivo analisar se a desaposentação é direito adquirido do trabalhador que mesmo após sua aposentadoria continua contribuindo e assim pretende ter seu benefício atualizado ou ao se acatar tal possibilidade se tornará mais um fator agravante da crise do sistema previdenciário brasileiro.

TOTALLY MAGIC INJECTIONS
Authors: D. Wallis W.
Published: February 2017

A labelling is a mapping whose domain is some set of graph elements- the set of vertices, for example, or the set of all vertices and edges - and whose range is a set of positive integers. In particular, if the labels associated with any edge - the label on the edge itself, and those on its endpoints -always add to the same sum, the labeling, and the graph possessing it, is called magic. A related concept, a vertex-magic total labeling, is one in which the sum of the label on any vertex with the labels on the edges containing it is always constant. A labeling which has both the vertex-magic and edge-magic properties (usually with two different constants) is called totally magic, as is a graph possessing such a labeling. In this paper we survey what is known about totally magic graphs and an important generalization.DOI : http://dx.doi.org/10.22342/jims.0.0.24.123-131
A FINITE DIFFERENCE METHOD FOR THE ONE-DIMENSIONAL VARIATIONAL BOUSSINESQ EQUATIONS
Authors: Suryanto A. , Groesen E. van
Published: February 2017

The variational Boussinesq equations derived by Klopman et. al. (2005) con-verse mass, momentum and positive-definite energy. Moreover, they were shown to have significantly improved frequency dispersion characteristics, making it suitable for wave simulation from relatively deep to shallow water. In this paper we develop a numerica lcode for the variational Boussinesq equations. This code uses a fourth-order predictor-corrector method for time derivatives and fourth-order finite difference method for the first-order spatial derivatives. The numerical method is validated against experimen-tal data for one-dimensional nonlinear wave transformation problems. Furthermore, the method is used to illustrate the dispersive effects on tsunami-type of wave propagation.DOI : http://dx.doi.org/10.22342/jims.14.1.57.1-11

Nor does it satisfy either of the usual Lipschitz or linear growth conditions.We characterize the boundary behaviour, identifying two possibilities: entrance boundaryand regular boundary. In the case of an entrance boundary we establish existence anduniqueness of the solution to the SDE.DOI : http://dx.doi.org/10.22342/jims.14.2.53.83-94
THE EXTREME POSITION AND AMPLITUDE AMPLIFICATION OF BICHROMATIC WAVES PROPAGATION BASED ON THIRD ORDER SOLUTION OF BOUSSINESQ EQUATION
Authors: . Marwan , . Andonowati
Published: February 2017

This paper concerns with the down-stream propagation of waves over initially still water. Such a study is relevant to generate waves of large amplitude in wave tankof a hydrodynamic laboratory. Input in the form of a time signal is provided at the wave-maker located at one side of the wave tank; the resulting wave then propagates over initially still water towards the beach at the other side of the tank. Experiments show that nonlinear effects will deform the waves and may lead to large wave with waves height larger than twice the original input; the deformation may show itself as peakingand splitting. It is direct scientific interest to understand and quantify the nonlinear distortion; it is also much practical interest to know at which location in the wave tank,the extreme position, the waves will achieve their maximum amplitude and to know the amplitude amplification factor. To investigate this, a previously introduced concept called Maximal Temporal Amplitude (MTA) is used: at each location the maximum over time ofthe wave elevation. An explicit expression of the MTA cannot be found in general from the governing equations and generating signals. In this paper we will use Boussinesq modeland third order approximation theory to calculate the approximate extreme positions and amplification factor for wave-group that originate from initially bi-chromatic type of wave. The wave is described by superposition of two monochromatic waves. We show that, the extreme position depends on the amplitude and the wave length of the group.The theoretical results are verified with numerical as well as experimental results for comparison.DOI : http://dx.doi.org/10.22342/jims.14.2.54.95-110

The Morse ﬁltration is smallerin size, yet has persistent homology equivalent to that of the original. We give anextension of acyclic matchings to the case of zigzag complexes and prove that theMorse zigzag complex similarly obtained has zigzag homology isomorphic to thatof the original. We present an algorithm to compute a Morse zigzag complex for agiven zigzag complex and some numerical examples. Since the Morse zigzag complexis smaller in size, calculations of its zigzag homology tend to complete faster thanthose for the original zigzag complex.DOI : http://dx.doi.org/10.22342/jims.20.1.177.47-75

Published: February 2017

An antimagic labeling of a graph with q edges is a bijection from the set of edges to the set of positive integers {1,2,...,q} such that all vertex weights are pairwise distinct, where the vertex weight of a vertex is the sum of the labels of all the edges incident with that vertex. A graph is antimagic if it has an antimagic labeling. In this paper we construct antimagic labeling for the family of generalized sausage graphs.DOI : http://dx.doi.org/10.22342/jims.20.2.184.95-110

We provide anidea to find out the dual of a matroid from the ways of conceptlattice drawing. In addition, we utilize the Hasse diagrams ofconcept lattices to discuss the minors of matroids, direct sum ofmatroids and the connectivity of a matroid. All the consequences demonstrate that the theory of concept lattice drawing can be usedinto matroids.

Simulation of temperature-pressure profiles and wax deposition in gas-lift wells
Authors: Sevic Snezana , Grubac Branko
Published: February 2017

Gas-lift is an artificial lift method in which gas is injected down the tubing- -casing annulus and enters the production tubing through the gas-lift valves to reduce the hydrostatic pressure of the formation fluid column. The gas changes pressure, temperature and fluid composition profiles throughout the production tubing string. Temperature and pressure drop along with the fluid composition changes throughout the tubing string can lead to wax, asphaltenes and inorganic salts deposition, increased emulsion stability and hydrate formation. This paper presents a new model that can sucesfully simulate temperature and pressure profiles and fluid composition changes in oil well that operates by means of gas-lift. This new model includes a pipe-in-pipe segment (production tubing inside production casing), countercurrent flow of gas-lift gas and producing fluid, heat exchange between gas-lift gas and the surrounding ambient ? ground; and gas-lift gas with the fluid in the tubing. The model enables a better understanding of the multiphase fluid flow up the production tubing. Model was used to get insight into severity and locations of wax deposition. The obtained information on wax deposition can be used to plan the frequency and depth of wax removing operations. Model was developed using Aspen HYSYS software.

Policy space in a financially integrated world: The Brazilian case in the 2000s
Authors: Feijo Carmem , Lamonica Marcos
Published: February 2017

This paper makes the argument that policy space in Brazil has been narrowing since the trade and capital opening made in the 1990s. This is so because the opening of the Brazilian economy has implied that real and nominal interest rates have been kept high and the real exchange rate has shown a trend towards appreciation. The behavior of the main macroeconomic prices of the Brazilian economy brought, as a minimum, two negative results to economic growth. On one hand, the annual average growth rate was reduced because structural change had been moving towards less technologically productive sectors, which deepened deindustrialization. On the other hand, short-term economic growth had become more volatile, given that the evolution of the investment position of the country increased its potential degree of external fragility.
Solar flares and variation of local geomagnetic field: Measurements by the Huancayo Observatory over 2001-2010
Authors: Carlos Reyes , Gárate Ayesta , Reyes Navarro
Published: February 2017

We study the local variation of the geomagnetic field measured by the
Huancayo Geomagnetic Observatory, Peru, during 2001-2010. Initially, we
sought to relate the SFI values, stored daily in the NOAA's National
Geophysical Data Center, with the corresponding geomagnetic index; however,
no relation was observed. Nonetheless, subsequently, a comparison between the
monthly geomagnetic-activity index and the monthly SFI average allowed
observing a temporal correlation between these average indices. This
correlation shows that the effect of the solar flares does not simultaneously
appear on the corresponding magnetic indices. To investigate this, we
selected the most intense X-class flares; then, we checked the magnetic field
disturbances observed in the Huancayo Geomagnetic Observatory magnetograms.
We found some disturbances of the local geomagnetic field in the second and
third day after the corresponding solar flare; however, the disturbance
strength of the local geomagnetic field is not correlated with the X-class of
the solar flare. Finally, there are some disturbances of the local
geomagnetic field that are simultaneous with the X-class solar flares and
they show a correlation with the total flux of the solar flare.

Published: February 2017

Introduction. Chylothorax is an accumulation of chyle in the pleural cavity due to a disruption of the thoracic duct. Traumatic chylothoraces are usually a result of a penetrating trauma and disruption of the thoracic duct, but blunt traumatic chylothorax is a rare condition. The aim of this paper is to present a rare case of traumatic chylothorax after blunt thoracic trauma. Case Outline. We present a case of traumatic chylothorax after blunt thoracic trauma in a patient injured in a motor vehicle accident. The patient had a right-sided fracture of rib XI, hydropneumothorax, lung contusion, and signs of pneumomediastinum. We performed thoracic drainage, but a few days later, according to the increase of amount of the fluid daily drained, and the confirmation of laboratory findings of the analyzed fluid, we made a diagnosis of chylothorax and the patient underwent a thoracotomy, where we sutured the thoracic duct. Conclusion. Chylothorax should be considered in patients after chest trauma if they develop a milky pleural effusion. Analysis of pleural fluid and level of triglycerides is important for the diagnosis and treatment of chylothorax.
The first planned liver resection in Serbia
Authors: Colovic Radoje
Published: February 2017

Perioperative bleeding, difficulties to establish a safe hemostasis, postoperative infections, biliary fistulas, and other possible complications were the reasons why operations on the liver were introduced more slowly and later then the ones on most other organs. A 26-year-old woman, who three years previously developed a moderate pain in the upper abdomen, where she initially noticed a small mass, which continued to rise gradually, followed by the increase in pain severity. She retained good appetite the entire time, had no loss in body mass, and did not vomit. On examination, a mass of the rough surface, the size of a ?male fist,? moderately sensitive on palpation, respiratory movable, hard on palpation, was found in the epigastrium and below the left costal margin. At an operation performed by V. Subbotic on July 4, 1922, under general anesthesia, a tumour the size of ?two male fists,? arising from the left lobe of the liver, covered by great omentum, was successfully resected. The postoperative recovery was uneventful. Three months after surgery, at the time of presentation, the patient was in good health, with no signs of recurrence. Histology showed primary carcinoma of the liver. The presented case was the first successful liver resection performed in a period when such operations were rare in Europe. The article speaks in favor of high level of surgery carried out by Dr. Vojislav Subbotic, the founder of modern surgery in Serbia, as well as the first professor of surgery of a newly founded Medical Faculty in Belgrade, of whom Serbian surgeons can be proud of. That is why his early death, which took place in a period when he was establishing a modern university surgical clinic, was a tremendous loss.

Published: February 2017

Introduction. The umbilicus (omphalos; the navel; belly button; tummy button) is important in a medical and psychosocial context. Umbilical tumors are rare and can be benign or malignant, primary or secondary. The most common are malignant metastatic tumors, especially The Sister Mary Joseph Nodule, an eponym for the umbilical metastasis of intra-abdominal malignant tumors. Primary melanoma of the umbilicus is very rare, there is few literature data about it and its incidence is not well known. Therefore, the aim of this study was to present a patient with a rare localization of the primary skin melanoma, that was, also, of atypical form, large and involved the whole umbilicus and surrounding skin. Case Report. In this report, the patient had nodular red tumor which involved the whole umbilicus. Tumor had rapid growth. In the differential diagnosis, the tumor most by resembled a pyogenic granuloma. After the surgery, the histopathological finding showed the primary nodular skin melanoma (Clark V, Breslow 10 mm, positive for: vimentim S ? 100 protein, melan ? A and HMB ? 45, and negative for EMA, with moderately high proliferative activity). Conclussion. According to literature data, this is 27th case of the primary melanoma of the umbilicus since 1916 when it was first reported. By presenting this rare clinical case, we emphasize that any skin lesion that is removed, must be sent to a histopathologic analysis.

Published: February 2017

Background/Aim. In the new millennium, the focus has been increasingly shifting to optimisation by enhancing the collaborative (common, joint) practice of healthcare professionals, for the purpose of achieving effectiveness and efficiency. Pharmacists are the last link in the healthcare services providing chain. The aim of this study was to present a critical analysis of the published models of the collaborative pharmacy practice along with development of a conceptual model of collaborative pharmacy practice in the healthcare and social care for the elderly population. Methods. Using two search algorithms that were created to search articles published in English, a comprehensive search of the bibliographic databases Web of Science and PubMed was undertaken (up to June 2015). Afterwards, articles were independently assessed by two authors, against predetermined inclusion and exclusion criteria. Results. Regulations on pharmacy collaboration are present in many developed countries. However, the implementation of the collaborative practice is still not widespread. Therefore, a conceptual model of the collaborative healthcare and social care of the elderly provides an insight into a multi-layer structure that has to be established in order to achieve a functioning system of the collaborative healthcare practice. The model concluded that aspirations towards teamwork, communication and above all ? the system of regulators and payers, who acknowledge a healthcare collaboration, are crucial for establishment of a collaborative healthcare practice. Conclusion. This research provides a tool in the form of a guide and check-list for decision-makers and policy-makers in order to achieve the preferred effects generated from the collaborative practice by selecting the models and activities that need to be undertaken for implementation of the collaborative healthcare and social care of the elderly that is best suited for their country.

Authors: Dragisic Tatjana , Jovanovic Mirjana , Dickov Aleksandra , Bugarski Tamara , Ivetic Olga , Miskovic Mirjana
Published: February 2017

Background/Aim. Suicide is a public health problem. Due to frequent overdose among drug addicts, there is a question about suicidality in this population. The aim of this study is to determine the specificity and distinctive factors in opiate addicts who have overdosed with an intention to commit suicide compared to addicts who have overdosed accidentally. Methods. The survey included 150 heroin addicts who were in the substitution program: 49 subjects who overdosed with a clear suicidal intention and 101 addicts who overdosed without suicidal intention. The subjects filled out the questionnaire about socio-demographic data and data regarding their addiction, the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) as well as the Manchester Short Assessment of Quality of Life (MANSA) questionnaire about the quality of life. For statistical analysis, Pearson's ?2 test, Student t-test and univariate variance analysis were used. Results. The addicts who attempted suicide w?re younger persons (29.7 vs. 36.3 years of age), started to take heroin earlier (17.8 vs. 21.3 years of age; p= 0.013), they use it for a longer period (14.1 vs. 9.2 years; p = 0.00) and take it intravenously for a longer period (11.6 vs. 6.5 years; p = 0.00). The suicide was preceded by a traumatic event (p = 0.015) and there were several attempts of suicide (p = 0.004). The quality of life regarding accommodation, friends and organization of their free time was assessed as not so good (p = 0.03). Conclusion. In accordance with the obtained data, it is necessary to design programs for the prevention of suicide among addicts in general and especially programs that would be aimed at younger addicts.
Incisor and molar overjet, arch contraction, and molar relationship in the mixed dentition in repaired complete unilateral cleft lip and palate: A qualitative and quantitative appraisal
Authors: Disthaporn Suteeta , Suri Sunjay , Ross Bruce , Tompson Bryan , Baena Diogenes , Fisher David , Lou Wendy
Published: February 2017

Objective:

To compare the mixed dentition incisor and molar overjet, severity of contraction of the dental arch, and the sagittal molar relationship on the cleft side vs the noncleft side in children with repaired complete unilateral cleft of the lip and palate (UCLP).

Materials and Methods:

Orthodontic records taken prior to orthodontic preparation for alveolar bone grafting were screened to select study casts from patients with nonsyndromic repaired complete UCLP who did not have mandibular skeletal or dental asymmetry. The study sample comprised dental casts from 74 children aged 8.9 ± 1 years. Standardized digital photographs were acquired at 1:1 magnification. A coordinate system was developed using digital image-processing software (Photoshop CS4 and Adobe Illustrator). Incisor and molar overjet, Angle's classification, and arch contraction were recorded. Descriptive statistics, paired t-tests, and kappa statistics were used to compare the cleft and noncleft sides.

Results:

A negative overjet of −1 to −5 mm was often present at the incisors, with greater frequency and magnitude on the cleft side. Class II molar relation was more frequent on the cleft side (61.1%) than on the noncleft side (47.2%). Significantly greater contraction of the cleft side deciduous canine and deciduous first molar was noted, while the difference was very minor at the first permanent molar.

Conclusions:

Cleft side maxillary arch contraction was most severe in the deciduous canine and first deciduous molar region and progressively less severe in the posterior region of the arch. A greater frequency and severity of negative overjet and Class II molar relationship was seen on the cleft side.

Prostaglandin E2 (PGE2) is derived from arachidonic acid, whereas PGE3 is derived from eicosapentaenoic acid (EPA) using the same downstream metabolic enzymes. Little is known about the impact of EPA and PGE3 on β-cell function, particularly in the diabetic state. In this work, we determined that PGE3 elicits a 10-fold weaker reduction in glucose-stimulated insulin secretion through the EP3 receptor as compared with PGE2. We tested the hypothesis that enriching pancreatic islet cell membranes with EPA, thereby reducing arachidonic acid abundance, would positively impact β-cell function in the diabetic state. EPA-enriched islets isolated from diabetic BTBR Leptinob/ob mice produced significantly less PGE2 and more PGE3 than controls, correlating with improved glucose-stimulated insulin secretion. NAD(P)H fluorescence lifetime imaging showed that EPA acts downstream and independently of mitochondrial function. EPA treatment also reduced islet interleukin-1β expression, a proinflammatory cytokine known to stimulate prostaglandin production and EP3 expression. Finally, EPA feeding improved glucose tolerance and β-cell function in a mouse model of diabetes that incorporates a strong immune phenotype: the NOD mouse. In sum, increasing pancreatic islet EPA abundance improves diabetic β-cell function through both direct and indirect mechanisms that converge on reduced EP3 signaling.

Authors: Qu Yanyang , Huang Jinglun , Zhao Yinqiao , Yang Guangcheng
Published: February 2017

Diode pump solid state lasers (DPSSLs) have been widely used in various fields such as material processing, the military, and medical and scientific research because of their high efficiency, long life, good beam quality, and compact structure. In this paper, a variety of refractive index matching cooling fluids was used in DPSSLs. Liquids examined include nontoxic and minimally toxic mineral oil (M98511), (KN-X (4006, 4010, 4016)), dialkyl ester compounds (B109815 and D109648), and chlorinated paraffin (041102-52). Their properties, including refractive index, temperature coefficient of the refractive index (DN/dt), dynamic viscosity, absorption coefficient, and thermal conductivity, were studied. The DN/dt of the matching liquid coolant was −3.6 × 10−4 to −3.9 × 10−4, and complete absorption at 808 ± 5 nm was better than 0.001%. Additionally, the best absorption coefficient at 1064 ± 5 nm reached 0.144%, which was much better than the Cargille samples 2.256%.

A new judging criterion for corrosion testing of reinforced concrete based on self-magnetic flux leakage
Authors: Zhang Hong , Liao Leng , Zhao Ruiqiang , Zhou Jianting , Yang Mao , Zhao Yayu
Published: February 2017

This paper presents a new judging principle for corrosion testing of steel bars buried in reinforced concrete based on the self-magnetic flux leakage. The magnetic field signals decrease monotonously with the increase of the lift-off height of the magnetic sensor, which denotes the distance between the magnetic sensor and the specimen surface, for the undamaged area of the reinforcing steel bar while a reversal phenomenon appears for the corroded area. The lift-off height related to the reversal point will increase with the increase of the corrosion degree, and the corroded area could also be extracted from the magnetic field data. The competition between the demagnetizing field and the magnetic flux leakage from the corroded area could be used to explain the phenomena. The results indicate that the lift-off height related to the reversal point can be acted as the judging criterion for assessing the corrosion degree and the corrosion area of the reinforcing steel bar. The findings have extensive application prospect for detecting and evaluating the corrosion degree of reinforced concrete in engineering practice.
Prescribing tamoxifen in primary care for the prevention of breast cancer: a national online survey of GPs’ attitudes
Authors: Smith Samuel G , Foy Robbie , McGowan Jennifer A , Kobayashi Lindsay C , DeCensi Andrea , Brown Karen , Side Lucy , Cuzick Jack
Published: February 2017

Background

The cancer strategy for England (2015–2020) recommends GPs prescribe tamoxifen for breast cancer primary prevention among women at increased risk.

Aim

To investigate GPs’ attitudes towards prescribing tamoxifen.

Design and setting

In an online survey, GPs in England, Northern Ireland, and Wales (n = 928) were randomised using a 2 × 2 between-subjects design to read one of four vignettes describing a healthy patient seeking a tamoxifen prescription.

Method

In the vignette, the hypothetical patient’s breast cancer risk (moderate versus high) and the clinician initiating the prescription (GP prescriber versus secondary care clinician [SCC] prescriber) were manipulated in a 1:1:1:1 ratio. Outcomes were willingness to prescribe, comfort discussing harms and benefits, comfort managing the patient, factors affecting the prescribing decision, and awareness of tamoxifen and the National Institute for Health and Care Excellence (NICE) guideline CG164.

Results

Half (51.7%) of the GPs knew tamoxifen can reduce breast cancer risk, and one-quarter (24.1%) were aware of NICE guideline CG164. Responders asked to initiate prescribing (GP prescriber) were less willing to prescribe tamoxifen than those continuing a prescription initiated in secondary care (SCC prescriber) (68.9% versus 84.6%, P<0.001). The GP prescribers reported less comfort discussing tamoxifen (53.4% versus 62.5%, P = 0.01). GPs willing to prescribe were more likely to be aware of the NICE guideline (P = 0.039) and to have acknowledged the benefits of tamoxifen (P<0.001), and were less likely to have considered its off-licence status (P<0.001).

Conclusion

Initiating tamoxifen prescriptions for preventive therapy in secondary care before asking GPs to continue the patient’s care may overcome some prescribing barriers.
Incorporating cancer risk information into general practice: a qualitative study using focus groups with health professionals
Authors: Usher-Smith Juliet A , Silarova Barbora , Ward Alison , Youell Jane , Muir Kenneth R , Campbell Jackie , Warcaba Joanne
Published: February 2017

Background

It is estimated that approximately 40% of all cases of cancer are attributable to lifestyle factors. Providing people with personalised information about their future risk of cancer may help promote behaviour change.

Aim

To explore the views of health professionals on incorporating personalised cancer risk information, based on lifestyle factors, into general practice.

Design and setting

Qualitative study using data from six focus groups with a total of 24 general practice health professionals from the NHS Nene Clinical Commissioning Group in England.

Method

The focus groups were guided by a schedule covering current provision of lifestyle advice relating to cancer and views on incorporating personalised cancer risk information. Data were audiotaped, transcribed verbatim, and then analysed using thematic analysis.

Results

Providing lifestyle advice was viewed as a core activity within general practice but the influence of lifestyle on cancer risk was rarely discussed. The word ‘cancer’ was seen as a potentially powerful motivator for lifestyle change but the fact that it could generate health anxiety was also recognised. Most focus group participants felt that a numerical risk estimate was more likely to influence behaviour than generic advice. All felt that general practice should provide this information, but there was a clear need for additional resources for it to be offered widely.

Conclusion

Study participants were in support of providing personalised cancer risk information in general practice. The findings highlight a number of potential benefits and challenges that will inform the future development of interventions in general practice to promote behaviour change for cancer prevention.

Les Maculinea (Lepidoptera, Lycaenidae) des zones humides : l'exemple de la Réserve naturelle du Marais de Lavours (Ain, France)
Authors: Rozier Yves
Published: February 2017

La disparition progressive des zones humides entraîne la raréfaction de nombreuses espèces floristiques et faunistiques. Les lycènes myrmécophiles du genre Maculinea sont gravement menacés, et donc inscrits sur de nombreuses listes de protection des invertébrés. Ils se caractérisent par la complexité de leurs cycles de vie, puisqu'ils dépendent à la fois d'une plante-hôte et d'une fourmi-hôte spécifiques. Au cours du suivi scientifique des deux espèces (Maculinea nausithous et M. teleius) présentes sur la Réserve naturelle du Marais de Lavours, la troisième espèce (M. alcon), inféodée aux milieux humides, a été découverte.
Nouvelle espèce du genre Typhlops (Serpentes, Typhlopidae) de l'île de Saint-Barthélemy, comparaison avec les autres espèces des Petites Antilles
Authors: Breuil Michel
Published: February 2017

New species of the genus Typhlops (Serpentes, Typhlopidae) from the island of Saint-Barthélemy, comparison with the other species of the Lesser Antilles.

A new species of the wormsnake Typhlops is described from the island of Saint-Barthélemy (Guadeloupe, French West Indies) where this snake genus was not previously known. The scales and coloration characteristics of the unique known specimen of the Saint-Barthélemy Typhlops allow to tell it without doubt from other Typhlops living in the Neotropics. This specimen is not an odd variant of a well-known species introduced in the island.
