Published: February 2018

Changes in retinal blood vessels feature a sign of serious illnesses such as heart disease and stroke. Therefore, the analysis of retinal vascular features can help in detecting these changes and allow patients to take preventive measures at an early stage of this disease. Automation of this process will help reduce the costs associated with the specialist and eliminate inconsistencies that occur in manual detection system. Among the retinal image analysis, image extraction retinal blood vessels is a crucial step before measurement. In this paper, we use an effective methodof automatically extracting the blood vessels of the color images of the retina using a length detector line in several different scales, in order to maintain the strength and eliminates the weaknesses of each detector individual lines, the result of the detection lines on various scales combined to produce a segmentation of each image of the retina. The performance of the method is evaluated quantitatively using DRIVE dataset. Test results show that this method achieve high accuracy is 0.9407 approaching measurement results manually by experts, and this method produces accurate segmentation in detecting retinal blood vessels with effiiency by quickly segmenting time is 2.5 seconds per image.

Published: February 2018

Abstract
Continuous drive friction welding (CDFW) and magnetic impelled arc butt (MIAB) welding are solid-state welding techniques, in which bonding is achieved at temperatures below the material melting point. Although CDFW welding has been widely used in automotive and aeronautics industry, MIAB welding has not been commonly used yet. The present study involves the comparison of CDFW and MIAB welding for joining medium carbon steel tubes and medium carbon forging brackets together, which are widely used for the construction of drivetrain applications in automotive industry. Optimum parameters are presented for both techniques by using macro- and microstructural analysis, hardness, tensile and petal tests. Based on the analyses presented in this study, MIAB welding can be an alternative to CDFW for structural automobile parts.
Effect of strain rate on stress corrosion cracking of X100 pipeline steel in environments with sulfate-reducing bacteria
Authors: Wu Ming , Gong Ke , Xie Fei , Wang Dan , Liu Guangxin 
Published: February 2018

Abstract
Pipelines installed in the seabed for long periods suffer from high stress levels, and the sea mud environment is complex because it contains various microorganisms that make pipelines prone to stress corrosion cracking (SCC). In this study, a self-designed stress electrochemical corrosion test device was adopted to ensure the normal growth and metabolism of sulfate-reducing bacteria (SRB). The effects of strain rate on the SCC behavior of X100 pipeline steel with SRB in a simulation solution of sea mud from the South China Sea were studied using the slow strain rate test, electrochemical impedance spectroscopy, and scanning electron microscopy fractography. Results show that SRB can promote the stress corrosion susceptibility of X100 pipeline steel. As strain rate increases, the stress corrosion susceptibility decreases in general. When the strain rate is 5 × 10−7 × s−1, the stress corrosion susceptibility is largest and SCC occurs. Under the impact of SRB and strain rate, the stress corrosion fracture mechanism is hydrogen embrittlement mechanism. With the increase in strain rate, the effect of SRB becomes weak and the stress corrosion susceptibility shows a decreasing trend in general. Consequently, SCC does not occur in the specimen and the fracture is dominated by mechanical factors.
Combined impact of UV radiation and nitric acid on HDPE containers during outdoor exposure
Authors: Geburtig Anja , Wachtendorf Volker , Schmidt Anita , Goedecke Thomas 
Published: February 2018

Abstract
Unpigmented HDPE jerrycans filled with nitric acid (55 wt.-%) and water respectively had been exposed to outdoor conditions for one Berlin summer season. As both liquids underwent equal temperature progression, exposure effects of UV radiation and nitric acid as well as of the combination of both can be separated and compared. On the basis of various property changes after these exposures, synergistic action is evaluated and compared to a damaged Intermediate Bulk Container (IBC) from a transport accident. It is found that carbonyl formation accompanies lightness increase in color measurement due to microcracking and with a worsening in mechanical behavior, all of them showing the synergistic effects of UV and nitric acid exposure. By contrast, embedding nitrogen compounds accompanies yellowing of the material but cannot be correlated to oxidation. The reason for intensified damaging is the decomposition of the 55-percent nitric acid and the formation of nitrogen oxides even at ambient temperatures, caused by UV radiation. Thus, damaging effects become similar to those caused by fuming nitric acid exposure at temperatures above 60 °C, resulting in strong oxidative degradation of the polyethylene. By contrast, exclusive exposure to the 55 wt.-% nitric acid at 40 °C does not cause any failure. It can therefore be assumed that the damaged IBC too had been exposed to both UV radiation and nitric acid, probably outdoors.

Published: February 2018

Abstract
Spark plasma sintering provides faster heating that can create fully, or near fully, dense samples without significant grain growth. In this study, pre-alloyed Ti-6Al-4 V powder compact samples produced through field assisted sintering in a spark plasma sintering machine are compared as a function of consolidation temperature. The effect of sintering temperature on the densification mechanism, microstructural evolution and mechanical properties of spark plasma sintered Ti-6Al-4 V alloy compacts was investigated in detail. The compact, sintered at 1100 °C, exhibited near net density, highest hardness and strength as compared to the other compacts processed at a temperature lower than 1100 °C.
Tribological performance of glass/epoxy composites filled with MWCNTs
Authors: Ovali İsmail 
Published: February 2018

AbstractThe effect of addition of multi-walled carbon nanotubes (MWCNTs) on the wear behaviour of glass/epoxy composites manufactured using the pre-preg method was investigated. The MWCNT filling rates were 0.5, 1, and 2 wt.%, and unfilled composite samples were used for comparison. The worn surfaces were characterised by means of scanning electron microscopy for evaluating the wear mechanisms. The experimental results showed that all the composites filled with MWCNTs have a lower wear loss than the unfilled composite sample, and the wear resistance increased with increase in the amount of MWCNTs. It is revealed that the abrasive wear resistance of the glass/epoxy composites is mainly related to the adhesion at the matrix and fibre interface.
A short history of scientific investigations on glaciers
Authors: Clarke Garry K.C. 
Published: February 2018

AbstractScientific investigations on valley glaciers engaged some of the greatest natural philosophers of the nineteenth century. Among these, Louis Agassiz has unique importance for he personifies the transition from the protoscientific period of de Saussure and Scheuchzer to the scientific one of Forbes and his successors. In this brief history I have attempted to connect the achievements of the past 50 years with the aspirations of our predecessors.“The air immediately above me seemed filled with rainbow-dust, for the ice-needles glittered with a thousand hues under the decomposition of light upon them, while the dark storm in the valley below offered a strange contrast to the brilliancy of the upper region in which I stood”.–Louis Agassiz“To myself, I confess that this now appears the strongest argument of all for considering the glacier as a united mass like a river, in which there is a nice equilibrium between the force of gravitation, acting by hydrostatic pressure, and the molecular resistance of the semi-solid; the degree of regularity of the law which connects the partial movements is wonderful, and I maintain that it is inexplicable except upon the viscous theory”.–James D.

History of snow-cover research
Authors: Colbeck S.C. 
Published: February 2018

AbstractThe history of snow-cover research is divided into four distinct periods. Before 1900 there were systematic observations of snow but the tools were just being developed to begin serious research. From 1900 to 1936, many investigations were made because of the practical considerations of snow hydrology and snow avalanches. Individuals began the assessment of snow water equivalent for forecasting run-off and the observation of snow structure and texture. Quantitative and physical investigations quickened after government-sponsored laboratories were established in 1936, the same year as the founding of the International Glaciological Society. From 1936 through the 1960s, many detailed investigations were made into snow's physical properties and behavior. Professional societies organized national and regional meetings, and published the results of snow research. Many more laboratories became involved as knowledge about snow was developed and applied to run-off forecasting and avalanche defense. Snow research surged again during the 1970s with the establishment of a new generation of snow scientists using more advanced theory, computers, and instrumentation. As demands continue for solutions to snow problems with new emphasis on old themes, snow research generates knowledge about snow for a wide variety of applications.
Factors influencing recording of drug misuse in primary care: a qualitative study of GPs in England
Authors: Davies-Kershaw Hilary , Petersen Irene , Nazareth Irwin , Stevenson Fiona 
Published: February 2018

BackgroundDrug misuse is a serious public health problem. Evidence from previous epidemiological studies show that GPs are recording drug misuse in electronic patient records (EPR). However, although the recording trends are similar to national surveys, recording rates are much lower.AimTo explore the factors that influence GPs to record drug misuse in the EPR, and to gain a clearer understanding of the gap between the amount of drug misuse recorded in primary care and that in national surveys and other studies.Design and settingA semi-structured qualitative interview study of GPs working in general practices across England.MethodPurposive sampling was employed to recruit 12 GPs, both with and without a special interest in drug misuse, from across England. Semi-structured face-to-face interviews were conducted to consider whether and why GPs record drug misuse, which methods GPs use for recording, GPs’ actions if a patient asks for the information not to be recorded, and GPs’ actions if they think a patient misuses drugs but does not disclose the information. Resulting data were analysed using a combination of inductive and deductive thematic analysis.ResultsThe complexity of asking about drug misuse preceded GPs’ decision to record. They described how the context of the general practice protocols, interaction between GP and patient, and the questioning process affected whether, how, and in which circumstances they asked about drug use. This led to GPs making a clinical decision on whether, who, and how to record in the EPR.ConclusionWhen making decisions about whether or not to record drug misuse, GPs face complex choices. Aside from their own views, they reported feelings of pressure from the general practice environment in which they worked and their clinical commissioning group, as well as government policies.

Abstract
Most Type I superluminous supernovae (SLSNe-I) reported to date have been identified by their high peak luminosities and spectra lacking obvious signs of hydrogen. We demonstrate that these events can be distinguished from normal-luminosity SNe (including Type Ic events) solely from their spectra over a wide range of light-curve phases. We use this distinction to select 19 SLSNe-I and four possible SLSNe-I from the Palomar Transient Factory archive (including seven previously published objects). We present 127 new spectra of these objects and combine these with 39 previously published spectra, and we use these to discuss the average spectral properties of SLSNe-I at different spectral phases. We find that Mn ii most probably contributes to the ultraviolet spectral features after maximum light, and we give a detailed study of the O ii features that often characterize the early-time optical spectra of SLSNe-I. We discuss the velocity distribution of O ii, finding that for some SLSNe-I this can be confined to a narrow range compared to relatively large systematic velocity shifts. Mg ii and Fe ii favor higher velocities than O ii and C ii, and we briefly discuss how this may constrain power-source models. We tentatively group objects by how well they match either SN 2011ke or PTF12dam and discuss the possibility that physically distinct events may have been previously grouped together under the SLSN-I label.
