Published: July 2018

We studied the physiological responses of Prunus mahaleb (Mahaleb) seedlings to drought stress when previously irrigated (or not) with different concentrations of SiO2 nanoparticles (SNPs). SNPs were applied at four concentrations (0, 10, 50 and 100 mg L-1) for 45 days, and then seedlings were subjected to three watering treatments including low (300 mL water every 3 d), moderate (150 mL water every 3 d) and severe drought stress (no irrigation) for 19 days. Results showed that gas exchange – photosynthesis, stomatal conductance, and transpiration rate – were significantly less impacted by severe drought stress when seedlings were pretreated with SNPs at high concentrations. Beneficial effects of SNPs pretreatment were evident in the nutritional status of the plants as the concentration of N, P and K, were maintained at similar levels than in well-watered seedlings. Pretreated seedlings were able to maintain the root length and to reduce the impact of severe drought on root dry mass accumulation. Therefore, application of SNPs as pretreatment should be considered as a promising agronomic practice in sites prone to suffer from water deficit.
The Izabal Geosol- A case of arrested development of a nickel laterite in Central America
Authors: Valls Ricardo A.
Published: July 2018

The Izabal Geosol is a new stratigraphic unit defined by the author within the Sierra de Santa Cruz (SSC) ophiolitic belt which is located to the north of Lake Izabal, in the east-central portion of Guatemala, some 140 km northeast from Guatemala City. The Geosol Izabal is composed of the following five pedosols: a. Gossan or Iron Cap (a.k.a. Ferricrete) b. Limonitic Horizon c. Stoneline Horizon d. Mottled Zone Horizon (a.k.a. Transition Zone) e. Saprolitic Horizon The Saprolitic Horizon lies over a Saprock Horizon, which, in turn, lies directly over a less weathered bedrock of the SSC ophiolitic belt. The most complete profiles are usually presented over weathered dunites and serpentinites, while on top of the less altered pyroxenites there usually forms only a limonitic horizon. The SSC ophiolitic belt overthrusted the Maya Block of the North American Continental Plate during the Early Tertiary period along a flat structure that outcrops at its base. The SSC is one of the five ophiolitic belts identified to date in Central Guatemala that are related to the northwestern border of the Caribbean Plate and, thus, to the ophiolitic belts from Cuba and Dominican Republic. The intrusives of this belt are composed of alternating layers of dunite and pyroxenites, usually strongly serpentinized. Existing data indicate that these rocks underwent fractional crystallization and probably some degree of magma mixing and contamination prior to their main tectonic event. The Izabal Geosol represents a case of arrested development of a wet lateritic profile, which develops mainly as large pockets controlled by tectonics and the presence of dunitic rocks. Its most striking difference from other wet laterites is the presence of up to 30% magnetite within the Saprolitic Horizon, which indicates relatively young age of these laterites. This magnetite carries nickel grades of 1.5 to 2% associated to nickel sulphides. It could represent a secondary product for a plant producing ferro-nickel or steel products. The presence of these large amounts of magnetite also allows the use of aeromagnetic surveys for the identification of areas of interest.

Social Smartphone Apps Do Not Capture Attention Despite Their Perceived High Reward Value
Authors: Johannes Niklas , Dora Jonas , Rusz Dorottya
Published: July 2018

Smartphones have been shown to distract people from their main tasks (e.g., studying, working), but the psychological mechanisms underlying these distractions are not clear yet. In the current study, we tested whether the distracting nature of smartphones stems from their high associated (social) reward value. Participants (N = 117) performed a visual search task while they were distracted by (a) high social reward cues (e.g., Facebook app icon + notification sign), (b) low social reward cues (e.g., Facebook app icon), and (c) no social reward cues (e.g., Weather app icon). We further expected that the distraction effect would be more pronounced for participants who had been deprived of using their phone. Contrary to our hypothesis, we found that smartphone cues that were presumably associated with high (vs. low or no) social rewards did not impair visual search speed. Surprisingly, deprived participants were faster than non-deprived participants. These results indicate that mere smartphone app icons are not necessarily associated with rewards. However, the absence of a smartphone may increase motivation which again may boost performance.
Culture and Wisdom
Authors: Kung Franki Y. H. , Grossmann Igor
Published: July 2018

The concept of wisdom is ancient and deeply embedded in the cultural history of humanity. However, only in the last few decades have psychologists begun to study it scientifically. We review emerging insights into the science of wisdom from a cultural psychological perspective, focusing on (a) cultural similarities and differences in epistemological traditions; (b) lay theories of wisdom (e.g., wisdom-related cognitions, affective processes, and prosociality), and (c) the role of socio-cultural affordances for the expression of wisdom-related characteristics in daily life. Overall, evidence suggests that wisdom is a culturally-situated and malleable construct, with culture playing a central role in shaping wisdom-related behaviors, supporting a constructionist account of wisdom and its development. Understanding of ecological and cultural-historical factors for the meaning and expression of wisdom is essential for the further advancement of psychological wisdom research.

Modeling of Solid Conveying Pressure Throughput Behavior of Single Screw Smooth Barrel Extruders under Consideration of Backpressure and High Screw Speeds
Authors: Trippe J. , Schöppner V.
Published: July 2018

The task of the solid conveying section is to collect the entering material and transfer it to the melt dominated sections. Therefore, its upstream interface is the hopper and its downstream interface is the section in which the first melting occurs. Beneath the hopper opening, the screw rotation collects and conveys the material forward. It is hereby assumed that the friction forces among the particles are higher than the transferring forces on the screw and barrel. For that reason commonly known models for describing the solid conveying in single screw extruders assume that the screw channel is always completely filled so that a plug flow occurs. At high screw speeds, however, these assumptions are no longer valid. To analyze and mathematically describe the solid conveying behavior at screw speeds up to 2000 rpm, simulations based on the Discrete Element Method have been executed in previous investigations. Based on this, a model for describing the solid conveying behavior was developed which enables a variation of general screw and hopper geometry parameters but neglects the backpressure that inhibits the solid movement. For that reason, further investigations based on the Discrete Element Method are presented in this paper, which enable a consideration of the backpressure and pressure build-up in the feeding zone. Astonishingly, at high screw speeds a low filling degree in the screw channel was observed which did not fulfill the expectations of an always fully filled channel due to a backpressure forced particle backlog. Based on the investigations, a mathematical model has been developed which now fully comprehends the effects occurring in the solid conveying section. The conducted simulations were subsequently validated by experimental investigations. Therefore, a test bench was designed which enables solid conveying analysis with adjustable backpressures. The results indicate a good agreement with the formulated model which now enables the calculation of solid conveying zones with consideration of the pressure build-up and filling degrees.
Influence of PA6 as a Charring Agent on Flame Retardancy, Thermal and Mechanical Properties of LGFR PP Composites
Authors: Wang M. , Li L.-T. , Wang N. , Chen X.-L. , Guo J.-B.
Published: July 2018

In this work, the combustion, thermal, and mechanical performances of long-glass-fiber-reinforced polypropylene/intumescent flame retardant (LGFPP/IFR) composites with different contents of polyamide 6 (PA6) as a charring agent were investigated by limiting oxygen index (LOI), UL-94 test, cone calorimetry, thermal gravimetric analysis (TGA), scanning electron microscopy (SEM), and mechanical property test. The results showed that LGFPP/IFR/PA6 composites exhibited much better flame retardancy due to the dense char layer structure, as proved by SEM. When 15 wt% PA6 was added, the LGFPP/IFR composites had the best flame retardancy, and LOI increased by 55.1 %, and the UL-94 reached V-0 rating. The cone calorimeter tests indicated that PA6 could prevent the transmission of heat and the volatilization of flammable substances, thereby reducing the heat release of “second burning”. According to TGA analysis, the carbon layer began to form at a lower temperature due to the synergistic effect between IFR and PA6. Moreover, the calculation of apparent active energy (Ea) revealed that PA6 effectively increased the Ea values of the composites, resulting in a better thermal stability and flame retardancy. In addition, PA6 enhanced the mechanical properties of the composites effectively.

Lateral lumbar interbody fusion in the elderly: a 10-year experience
Authors: Agarwal Nitin , Faramand Andrew , Alan Nima , Tempel Zachary J. , Hamilton D. Kojo , Okonkwo David O. , Kanter Adam S.
Published: July 2018

OBJECTIVE

Elderly patients, often presenting with multiple medical comorbidities, are touted to be at an increased risk of peri- and postoperative complications following spine surgery. Various minimally invasive surgical techniques have been developed and employed to treat an array of spinal conditions while minimizing complications. Lateral lumbar interbody fusion (LLIF) is one such approach. The authors describe clinical outcomes in patients over the age of 70 years following stand-alone LLIF.

METHODS

A retrospective query of a prospectively maintained database was performed for patients over the age of 70 years who underwent stand-alone LLIF. Patients with posterior segmental fixation and/or fusion were excluded. The preoperative and postoperative values for the Oswestry Disability Index (ODI) were analyzed to compare outcomes after intervention. Femoral neck t-scores were acquired from bone density scans and correlated with the incidence of graft subsidence.

RESULTS

Among the study cohort of 55 patients, the median age at the time of surgery was 74 years (range 70–87 years). Seventeen patients had at least 3 medical comorbidities at surgery. Twenty-three patients underwent a 1-level, 14 a 2-level, and 18 patients a 3-level or greater stand-alone lateral fusion. The median estimated blood loss was 25 ml (range 5–280 ml). No statistically significant relationship was detected between volume of blood loss and the number of operative levels. The median length of hospital stay was 2 days (range 1–4 days). No statistically significant relationship was observed between the length of hospital stay and age at the time of surgery. There was one intraoperative death secondary to cardiac arrest, with a mortality rate of 1.8%. One patient developed a transient femoral nerve injury. Five patients with symptomatic graft subsidence subsequently underwent posterior instrumentation. A lower femoral neck t-score < −1.0 correlated with a higher incidence of graft subsidence (p = 0.006). The mean ODI score 1 year postoperatively of 31.1 was significantly (p = 0.003) less than the mean preoperative ODI score of 46.2.

CONCLUSIONS

Stand-alone LLIF can be safely and effectively performed in the elderly population. Careful evaluation of preoperative bone density parameters should be employed to minimize risk of subsidence and need for additional surgery. Despite an association with increased comorbidities, age alone should not be a deterrent when considering stand-alone LLIF in the elderly population.

В результате, при стремлении композитора к созданию музыкальной драмы, вокальная партия Радамеса является одной из самых сложных в мировом оперном репертуаре, оказавшая воздействие на дальнейшее развитие оперного исполнительства.  Ключевые слова: Верди, «Аида», Радамес, героизм, конфликт.
Estimating the Impact of School Education on Contraception Use among Adolescents Aged 15–19 in Burkina Faso and Nigeria: Evidence from a Heckman Two-Step Correction Model
Authors: Bago Jean-Louis , Lompo Miaba Louise , Souratié Wamadini dite Minata
Published: July 2018

Sexually Transmitted Infections (STIs) still raise serious concerns for adolescents’ sexual health in west-Africandeveloping countries. To this extent, promoting contraception use among sexually active adolescents is a major key to addressing this problem. Yet, the rate of contraception use by adolescents remains surprisingly low in these countries. Using the Demographic Health Survey of Burkina Faso (2014) and Nigeria (2013), this paper examines the influence of school education on contraception use among sexually active male and femaleadolescents aged 15-19 in Burkina Faso and Nigeria. The standard estimates using Probit regressions suggestthat achieving a primary school education increases the probability of a sexually active adolescent to usecontraception by 8.26 percentage points (Burkina Faso) and 17.2 percentage points (Nigeria). This effectincreases to 20.3 percentage points (Burkina Faso) and 34.7 percentage points (Nigeria) for adolescents with asecondary or higher school education. However, these baseline estimates are biased because adolescents’decision to engage into sexual activity is not random. In light of this, a Heckman Correction Model (HCM) hasbeen applied to account for this selection bias. The results show that the Probit regressions underestimate theeffect of education on adolescents’ likelihood to use contraception in Burkina Faso and overestimate this effect in Nigeria. In fact, compared to adolescents with no school education, HCM estimates show that adolescentswith primary and secondary (or higher) school education have respectively 10.2 and 24.4 percentage points morein the use of contraception in Burkina Faso and 15.1 and 34 percentage points in Nigeria. Together, these resultssuggest that the exposure to school education increases contraception use among the adolescents in both BurkinaFaso and Nigeria.

The saga of the Edinburgh Trams, and ensuing Public Inquiry, sheds light on systems of power and influence in the city. Drawing mainly upon Inquiry evidence, this article gives an account of why the project was over-budget, curtailed in length, and failed to meet the original timetable. It examines how blame was apportioned by key actors. In terms of analysis, the article explores the Trams as a ‘mega-project’, and locates it in the context of outsourcing the state, both national and local. More generally, it treats Edinburgh as an example of the ‘calculable city’, in which assets are treated as future forms of revenue rather than as public resources.
A Novel Parallel Auto-Encoder Framework for Multi-Scale Data in Civil Structural Health Monitoring
Authors: Wang Ruhua , Li Ling , Li Jun
Published: July 2018

In this paper, damage detection/identification for a seven-storey steel structure is investigated via using the vibration signals and deep learning techniques. Vibration characteristics, such as natural frequencies and mode shapes are captured and utilized as input for a deep learning network while the output vector represents the structural damage associated with locations. The deep auto-encoder with sparsity constraint is used for effective feature extraction for different types of signals and another deep auto-encoder is used to learn the relationship of different signals for final regression. The existing SAF model in a recent research study for the same problem processed all signals in one serial auto-encoder model. That kind of models have the following difficulties: (1) the natural frequencies and mode shapes are in different magnitude scales and it is not logical to normalize them in the same scale in building the models with training samples; (2) some frequencies and mode shapes may not be related to each other and it is not fair to use them for dimension reduction together. To tackle the above-mentioned problems for the multi-scale dataset in SHM, a novel parallel auto-encoder framework (Para-AF) is proposed in this paper. It processes the frequency signals and mode shapes separately for feature selection via dimension reduction and then combine these features together in relationship learning for regression. Furthermore, we introduce sparsity constraint in model reduction stage for performance improvement. Two experiments are conducted on performance evaluation and our results show the significant advantages of the proposed model in comparison with the existing approaches.

Despite their long success for more than half a century, antibiotics are currently under the spotlight due to the emergence of multidrug-resistant bacteria. The development of new alternative treatments is of particular interest in the fight against bacterial resistance. Bacteriophages (phages) are natural killers of bacteria and are an excellent tool due to their specificity and ecological safety. Here, we highlight some of their advantages and drawbacks as potential therapeutic agents. Interestingly, phages are not only attractive from a clinical point of view, but other areas, such as agriculture, food control, or industry, are also areas for their potential application. Therefore, we propose phages as a real alternative to current antibiotics.

Atmospheric deposition of long-range transported continental substances from natural and anthropogenic sources affects biogeochemical processes in marine systems. Emissions of sea spray contribute aerosol particles to the marine atmosphere. Despite the importance of continental dispersion and atmospheric processes involving aerosol particles within remote marine atmosphere, knowledge of the sources of various water-soluble ions is limited because of insufficient observations. Concentrations of Total suspended particulates (TSPs) and major inorganic ions (Cl−, Na+, SO42−, Mg2+, Ca2+, K+, NO3−, NH4+), as well as organic nitrogen (ON-N) values, were measured in marine aerosol collected over the western north Pacific (WNP) during a cruise from 3 December 2014 to 13 March 2015. Aerosol samples were analyzed to determine their chemical characteristics and a source apportionment for this region and the continental influence on the open ocean when air masses are from continent in winter. TSP mass concentrations ranged from 14.1 to 136.0 μg/m3 with an average of 44.8 ± 28.1 μg/m3. Concentrations of TSPs and major ions were higher near the coast (close to Qingdao and Xiamen) and lower over the open ocean. The total mass of inorganic ions and organic nitrogen accounted for 51.1% of the total TSP. Cl− had highest concentrations among the major inorganic ions, followed by SO42−, NO3−, Mg2+, Ca2+, K+, and NH4+, respectively. However, Cl− showed a deficit relative to Na+ in most samples, likely related to heterogeneous reactions within the marine atmosphere. Most SO42−, Mg2+, Ca2+, and K+ were from sea salt, while other major ions were from continental sources. The non-sea-salt (nss) fractions of Ca2+, Mg2+ and K+ were derived from continental crust, while nss-SO42− and NO3− were derived from anthropogenic sources. ON had several sources, including reactions of NOx with volatile organic compounds (anthropogenic sources) or NH3 with gaseous hydrocarbons, as well as crustal and marine biogenic sources.
Co-, Cu- and Fe-Doped Ni/Al2O3 Catalysts for the Catalytic Decomposition of Methane into Hydrogen and Carbon Nanofibers
Authors: Torres Daniel , Pinilla José Luis , Suelves Isabel
Published: July 2018

The catalytic decomposition of methane (CDM) process produces hydrogen in a single stage and avoids CO2 emission thanks to the formation of high added value carbon nanofilaments as a by-product. In this work, Ni monometallic and Ni–Co, Ni–Cu, and Ni–Fe bimetallic catalysts are tested in the CDM reaction for the obtention of fishbone carbon nanofibers (CNF). Catalysts, in which Al2O3 is used as textural promoter in their formulation, are based on Ni as main active phase for the carbon formation and on Co, Cu, or Fe as dopants in order to obtain alloys with improved catalytic behaviour. Characterization of bimetallic catalysts showed the formation of particles of Ni alloys with a bimodal size distribution. For the doping content studied (5 mol. %), only Cu formed an alloy with a lattice constant high enough to be able to favor the carbon diffusion through the catalytic particle against surface diffusion, resulting in higher carbon formations, longer activity times, and activity at 750 °C; whereas Ni, Ni–Co, and Ni–Fe catalysts were inactive. On the other hand, Fe also improved the undoped catalyst performance presenting a higher carbon formation at 700 °C and the obtention of narrow carbon nanofilaments from active Ni3Fe crystallites.
Microstructure and Oxidation Resistance of a Si Doped Platinum Modified Aluminide Coating Deposited on a Single Crystal Superalloy
Authors: Fan Qixiang , Yu Haojun , Wang Tiegang , Liu Yanmei
Published: July 2018

A Si doped Pt modified aluminide coating was prepared by electroplating and the chemical vapour deposition method. The microstructure and oxidation resistance of the coating were studied, with a single Pt modified aluminide coating as a reference. The results showed that the Si doped Pt modified aluminide coating consisted of singular β-(Ni, Pt)Al phase, and no PtAl2 phase was detected, which might be due to the fact that the addition of Si retarded the formation of PtAl2 phase in the outer layer. Si was dissolved in the β-(Ni, Pt)Al phase in the outer layer and might form silicide with refractory elements in the inter-diffusion zone. The Si doped Pt modified aluminide coating possesses a better oxidation resistance than the Pt modified aluminide coating since Si could promote the formation of α-Al2O3 and inhibit the diffusion of the refractory elements, reducing the formation of detrimental volatile phase.
Habit Change of Monoclinic Hydroxyapatite Crystals Growing from Aqueous Solution in the Presence of Citrate Ions: The Role of 2D Epitaxy
Authors: Pastero Linda , Bruno Marco , Aquilano Dino
Published: July 2018

Calcium hydroxyapatite (HAp) has been crystallized from aqueous solutions in the presence of citrate ions, in two temperature intervals. At lower temperature, where citrate could form the stable 3D-ordered phase Ca-citrate-tetrahydrate (Ca-Cit-TH), only the monoclinic (P21/c) HAp polymorph occurs and assumes the shape of fence-like aggregates, built by sharply [010] elongated lamellae dominated by the pinacoid {001}. This pronounced anisotropic growth habit is compared with the usually considered rod-like pseudo-hexagonal occurring in pure aqueous solution growth. The habit change is interpreted by assuming that 2D islands of Ca-citrate-tetrahydrate can be adsorbed as epi- monolayers of thickness d001 onto the different growth forms: {001}, {100}, {102¯}, {010}, and {101¯} of HAp. A comparison is made among the corresponding coincidence lattices, in order to explain on reticular basis the selective adsorption of citrate on the {001} HAp form. The role exerted by the 2D-epitaxially adsorbed Ca-Cit-TH as a “mortar” in the monoclinic HAp “brick” assembly is outlined as well.
Kuschelysius, a New Alpine Genus of Eugnomine Weevil (Coleoptera: Curculionidae: Curculioninae) from New Zealand
Authors: Brown Samuel , Leschen Richard
Published: July 2018

Kuschelysius new genus is described for four species, K. hollowayae new species, K. durus new species, K. verbalis new species and K. nitens new species, which are found in alpine regions along the length of the South Island of New Zealand. The genus most closely resembles members of the genus Eugnomus but is distinguished from them by the presence of a small pair of post-ocular tubercles and by having appressed scales on the dorsal surfaces. Some members of Kuschelysius appear to be flight-capable with well-developed hindwings, while others have reduced hindwings and are presumably flightless. Many specimens have been collected from the flowers of Dracophyllum traversii, Celmisia and other alpine plants, and the guts of examined specimens contained pollen. We hypothesise that the species of Kuschelysius are pollinators of the New Zealand alpine flora.

Prostate cancer is the third highest cause of male mortality in the developed world, with the burden of the disease increasing dramatically with demographic change. There are significant limitations to the current diagnostic regimens and no established effective screening modality. To this end, research has discovered hundreds of potential ‘biomarkers’ that may one day be of use in screening, diagnosis or prognostication. However, the barriers to bringing biomarkers to clinical evaluation and eventually into clinical usage have yet to be realised. This is an operational challenge that requires some new thinking and development of paradigms to increase the efficiency of the laboratory process and add ‘value’ to the clinician. Value comes in various forms, whether it be a process that is seamlessly integrated into the hospital laboratory environment or one that can provide additional ‘information’ for the clinical pathologist in terms of risk profiling. We describe, herein, an efficient and tissue-conserving pipeline that uses Tissue Microarrays in a semi-automated process that could, one day, be integrated into the hospital laboratory domain, using seven putative prostate cancer biomarkers for illustration.
