An experimental analysis on physical properties and spray characteristics of an ultrasound-assisted emulsion of ultra-low-sulphur diesel and Jatropha-based biodiesel

Among the effective solutions for the reduction of environmental pollution, the use of fuels with limited-sulphur content or bio-based fuel has been paid much attention due to their advantages. In this experimental work, the ultra-low-sulphur fuel (ULSD) was mixed with biodiesel extracted from Jatropha oil (JOB) after being processed with ultrasonic assistance. There were eight samples used for mixture preparation of ULSD and JOB based on the correlation of viscosity aiming to find the optimal mixing rate for ULSD and JOB. As a result, the stability of the ULSD–JOB emulsion reached 98.5% after 17 min of the ultrasonic treatment with a mixing rate of 50%(ULSD): 50%(JOB) in the case of a distance of ultrasound horn tip to the bottom of vessel of 90 mm. In addition, the similarity of spray characteristics, being penetration length and cone angle, for the ULSD–JOB emulsion compared to a type of diesel oil was reported. The ULSD–JOB emulsion produced by ultrasound delivered a fuel with the ultra-low-sulphur content and increased oxygen content. The above-mentioned emulsion has well satisfied the increasingly stricter requirements of IMO regulations, as well as meeting the recommendations of engine manufactures regarding the fuels used in marine diesel engines.

Petiole length and crown area also exhibited significant and positive correlation with green leaf yield. Best performance was shown by clones Tr10, S146 and Mandaley with respect to various morphometric traits.
University of Birmingham Persistent residential burning-related primary organic particles during wintertime hazes in North China

Primary organic aerosols (POAs) are a major component of PM 2 . 5 in winter polluted air in the North China Plain (NCP), but our understanding of the atmospheric aging processes of POA particles and the resulting inﬂuences on their optical properties is limited. As part of the Atmo-spheric Pollution and Human Health in a Chinese Megacity (APHH-Beijing) program, we collected airborne particles at an urban site (Beijing) and an upwind rural site (Gucheng, Hebei province) in the NCP during 13–27 November 2016 for microscopic analyses. We conﬁrmed that large numbers of light-absorbing spherical POA (i.e., tarball) and irregular POA particles with high viscosity were emitted from domestic coal and biomass burning at the rural site and were further transported to the urban site during regional win-tertime hazes
&yleigh-wave amplitudes from earthquakes in the range 0-150"

Summary. Vertical component Rayleigh-wave amplitudes from 1461 shallow earthquakes recorded in the distance range 0-150" are analysed to separate the effects of earthquake size, epicentral distance (A) and recording station. The estimated decay of amplitude with distance has the form of a theoretical curve for the decay of Rayleigh waves with distance if the assumption is made that the decay due to dispersion for the data analysed is that of an Airy phase. Writing the decay due to anelastic attenuation as exp (-kA), k is estimated to be 0.676/rad over the whole range of distance. If the distance effects are represented by a straight line of the form h log A + constant, h is estimated to be 1.15. The calibration function for computing M, derived from the estimated distance effects is very similar to that of Marshall & Basham. Station effects on Rayleigh-wave amplitudes though statistically significant are small, and can probably be ignored in the computation of M,. Comparing the surface-wave Young same shows that m i P is about equal to M, over the range of 4.0-7.0). The mEp and M, relationship shows that the greater the long-period energy radiated by an the smaller pro-portionately is the short-period energy.
Emergence Antecedents of Enterprise Social Media Networks: A Literature Review and Directions for Future Research

What drives the emergence of enterprise social media (ESM) networks? This question cannot be fully answered without studying the scattered body of knowledge. The current research in progress paper addresses this question by means of a preliminary literature review. Precisely, it synthesizes 34 literature findings into a preliminary literature review, which will be further refined and augmented by a research agenda in the future steps. The main theoretical contribution of this paper is to describe 21 antecedents that drive ESM network emergence. In practice, knowledge about these emergence antecedents can be used for various application cases. Examples include developing ESM recommender systems, creating ESM network simulation models, and planning and conducting organizational interventions to optimize ESM networks.
Electrospun Nanometer to Micrometer Scale Biomimetic Synthetic Membrane Scaffolds in Drug Delivery and Tissue Engineering: A Review

The scaffold technology research utilizes biomimicry to produce efficient scaffolds that mimic the natural cell growth environment including the basement membrane for tissue engineering. Because the natural basement membrane is composed of fibrillar protein networks of nanoscale diameter, the scaffold produced should efficiently mimic the nanoscale topography at a low production cost. Electrospinning is a technique that can achieve that. This review discusses the physical and chemical characteristics of the basement membrane and its significance on cell growth and overall focuses on nanoscale biomimetic synthetic membrane scaffolds primarily generated using electrospinning and their application in drug delivery and tissue engineering.
A Static-loop-current Attack Against the Kirchhoff-Law-Johnson-Noise (KLJN) Secure Key Exchange System

In this study, a new attack against the Kirchhoff-Law-Johnson-Noise (KLJN) key distribution system is explored. The attack is based on utilizing a parasitic voltage-source in the loop. Relevant situations often exist in the low-frequency limit in practical systems, especially when the communication is over a distance, or between different units within an instrument, due to a ground loop and/or electromagnetic interference (EMI). Our present study investigates the DC ground loop situation when no AC or EMI effects are present. Surprisingly, the usual current/voltage comparison-based defense method that exposes active attacks or parasitic features (such as wire resistance allowing information leaks) does not function here. The attack is successfully demonstrated and proposed defense methods against the attack are shown.
FACTORS INFLUENCING THE PROFESSIONAL DEVELOPMENT: OPINIONS OF SCHOOL PRINCIPALS IN GREECE

The importance of the present research arises from the value that has been given – at the national, European, and international level – to the work of the teacher and the necessity of his or her professional development but also in the research gap that exists in this field. The aim of the research was to clarify the views of school principals on factors influencing their professional development. A questionnaire was administered through the Google form. The data were analyzed using the SPSS v.25. To reply to the research questions, the non-parametric Kruskal-Wallis and the Pearson coefficient were used to assess the statistical significance of the data. The sample consisted of 100 primary school principals in Greece. The results of the study showed differences in attitudes towards professional development between heads of primary education institutions with different specializations. Participants with a specialization in math and computer sciences more often supported the idea that their professional development depends on their basic studies. Those who specialized in humanities, agreed on a higher level that their professional development depends on their first two years of education experience, participation in introductory training programs, participation in training programs organized by the state and on the school culture, and their transition to another school or position. The participants who followed a science field were more positive about their professional development depending on their participation in European mobility programs, the professional support they get from their colleagues, and the way the school leadership is practiced. There were differences in the understanding of the role of the educational institution in supporting the professional development of teachers depending on the professional experience of the participants: its importance was recognized by teachers who had less than five or more than thirty years of professional experience. It was found that the more positive was the attitude of the participants toward their own professional development, the wider range of needs for further training they expressed. Most often, such needs related to improving professional competence in such areas as classroom management, solving problems with complex student behavior and school discipline, counseling, and assessment of students.

Orthodontic treatment can be part of a dental interdisciplinary treatment as a way to help other specialists in the team achieve efficient treatment results when dealing with complex cases. The team members must have basic and sufficient knowledge related to other disciplines if they are to have common ground for fruitful discussion of treatment options and possible solutions that will provide optimum esthetics and function, especially for adult patients. This article discusses important factors related to endodontics, periodontics, and restorative/prosthodontics and their interactions with orthodontics.
Effect of the Systemic Neonicotinoid Insecticide Dinotefuran on Leaf-level Photosynthesis in Loblolly Pine ( Pinus taeda )

Bark beetles (Coleoptera: Curculionidae: Scolytinae) are a common pest in loblolly pine ( Pinus taeda L.) plantations, and climate intensification threatens to increase the range of bark beetle infestation and vulnerability of loblolly pine. New insecticides and management options are needed to maintain loblolly pine plantation productivity, mitigating increased bark beetle risk. The systemic neonicotinoid insecticide dinotefuran (Safari 20SG systemic insecticide, Valent USA, LLC), is utilized by nursery managers to protect loblolly pine from bark beetles, but there is little published literature on the insecticide’s potential phytotoxicity. The objective of this study was to evaluate the effect of dinotefuran on the leaf-level photosynthesis of three loblolly pine genotypes. Dinotefuran was applied to lower tree boles, and photosynthetic measurements occurred two months later. Dinotefuran did not significantly impact leaf-level gross photosynthesis (P gmax ), light- saturated net photosynthesis (P net ) or dark respiration (R d ); nor was there any significant genotypic variation in responses. Dinotefuran appears to be a promising insecticide for bark beetle prevention without risk of foliar toxicity.
Effects of Ground Motion Duration on the Seismic Performance of a Two-Storey Balloon-Type CLT Building

The effects of long duration ground motions on the seismic performance of a newly constructed two-storey balloon-type cross-laminated timber (CLT) building located in Vancouver, Canada, was studied. A three-dimensional numerical model of the building was developed in OpenSees. The connection and shear wall models were validated with test data. Twenty-four pairs of long and short duration records with approximately the same amplitude, frequency content, and rate of energy build-up were used for nonlinear dynamic analyses. Fragility curves were developed based on the results of incremental dynamic analysis to assess the building’s collapse capacity. At design intensity level, ground motion duration was shown not to be a critical factor as the difference in inter-storey drift ratio between the two sets of records was negligible. However, due to the larger number of inelastic cycles, the long duration motions increased the median probability of collapse by 9% when compared with the short duration motions. Further research is required to evaluate the duration effects on taller and platform-type CLT buildings.
The HARPS search for southern extra-solar planets - XXXIV. A planetary system around the nearby M dwarf GJ 163, with a super-Earth possibly in the habitable zone

The meter-per-second precision achieved by today velocimeters enables the search for 1 10 M planets in the habitable zone of cool stars. This paper reports on the detection of 3 planets orbiting GJ 163 (HIP19394), a M3 dwarf monitored by our ESO/HARPS search for planets. We made use of the HARPS spectrograph to collect 150 radial velocities of GJ 163 over a period of 8 years. We searched the RV time series for coherent signals and found 5 distinct periodic variabilities. We investigated the stellar activity and casted doubts on the planetary interpretation for 2 signals. Before more data can be acquired we concluded that at least 3 planets are orbiting GJ 163. They have orbital periods of Pb = 8:632 0:002, Pc = 25:63 0:03 and Pd = 604 8 days and minimum masses m sini = 10:6 0:6, 6:8 0:9, and 29 3 M , respectively. We hold our interpretations for the 2 additional signals with periods P(e) = 19:4 and P(f ) = 108 days. The inner pair presents an orbital period ratio of 2:97, but a dynamical analysis of the system shows that it lays outside the 3:1 mean motion resonance. GJ 163c, in particular, is a super-Earth with an equilibrium temperature of Teq = (302 10)(1 A) 1=4 K and may lie in the so called habitable zone for albedo values (A = 0:34 0:89) moderately higher than that of Earth (A = 0:2 0:3).
CEREBROVASCULAR DISEASE AND DEMENTIA

Cerebrovascular disease is a major contributor to later-life dementia, accounting for up to 20% of cases of dementia. Atherosclerotic and arteriolosclerotic mechanisms account for most of the burden of disease. Cerebrovascular disease may take several forms. Macrovascular disease in the form of large vessel and larger arteriole infarcts produce a wide spectrum of clinical syndromes. Single strategic infarctions, multiple bilateral infarctions and multiple lacunar infarctions can lead to cognitive dysfunction that spans a large range of both severity and type of cognitive deficits. Microvascular disease almost certainly plays a role in the pathogenesis of dementia. Small vessel disease, which is not evident radiographically, often coexists with macrovascular disease and also with Alzheimer’s disease. Amyloid angiopathy is relevant in cognitive disorders in the elderly and causes micro-haemorrhages and large haemorrhages. Other much less common aetiologies include vasculitides and CADASIL (cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy). Neuroimaging plays a critical role in the diagnosis of vascular dementia. There is no framework for rating the extent of cerebrovascular pathology that is validated against increasing cognitive impairment. Although advances in imaging have increased our recognition of cerebrovascular disease in the elderly, vascular dementia is still inadequately recognized in clinical practice.
The Utilisation of Capabilities in Born Globals’ Internationalisation Process

The subject of research in this paper is born globals’ utilisation of capabilities in their internationalisation process. The purpose of this multiple case study is to gain a deeper understanding of what and how capabilities Swedish born globals utilise when expanding abroad. Prior research relating to born globals and capabilities is dispersed and additional studies relating to born globals’ internationalisation is needed. In the field of capabilities, the attention has mainly been directed towards established companies whereas studies relating to new ventures capabilities remains under researched. The study is executed through a multiple case study of six Swedish born global firms. The findings of the multiple case study indicate that networking capabilities and internally focused learning capabilities seem to be utilised to a great extent by the examined case companies. The internally focused learning capabilities enables the firms to develop superior products and have a higher degree of adaptability in comparison with competitors. Furthermore, the networking capabilities are utilised by the born global firms in order to cope with uncertainties and exploit new business opportunities. In addition, the findings show that logistics capabilities for non-IT born globals can be a prerequisite for their internationalisation due to its need to deliver product worldwide in a timely and cost-effective manner.
Comparison between immediate and delayed post space preparation on the apical seal prepared by hand protaper instruments

Forty single-rooted human mandibular premolar were instrumented with hand ProTaper instruments and obturated with gutta-percha and Zinc oxide eugenol sealer. Then all teeth were divided to two group the first group received immediate post space preparation half teeth with hot plugger and other half with peeso reamer, the roots were coated with nail varnish and were immersed in methylene blue 2% for 72 hours in an incubator. After one week the other group received delayed post space preparation same as the first group and coated with nail varnish and were immersed in methylene blue 2% for 72 hours in an incubator. All roots splitted longitudinally and the apical leakage measured and compared for each group. The minimal leakage value and the lowest mean of leakage were observed in subgroup one, while the maximum leakage value and the highest mean of leakage was obvious in subgroup four. A significant difference was found in the group of roots that received delayed post space preparation using peeso reamers, which showed more apical leakage than other subgroups.
A Canadian cost-effectiveness analysis of SAPIEN 3 transcatheter aortic valve implantation compared with surgery, in intermediate and high-risk severe aortic stenosis patients

Background and objectives: The treatment of severe aortic stenosis requires replacement of the defective native valve. Traditionally, this has been done via surgery, but in the last 10 years, transcatheter techniques have emerged. Transcatheter aortic valve implantation (TAVI) is a less invasive option compared to surgical aortic valve replacement (SAVR), and this study evaluates the cost-effectiveness of TAVI versus SAVR in intermediate and high surgical risk patients in Canada. Methods: A Markov model was used to project the costs and quality-adjusted life years (QALYs) gained for TAVI using the SAPIEN 3 valve and SAVR over a 15-year time horizon. The PARTNER I and II studies were used to populate the model in terms of survival, clinical event rates and quality of life over time. The costs of TAVI with SAPIEN 3 and SAVR as well as the costs associated with events included in the model were derived from Canadian administrative and literature data. Costs were expressed in 2018 Canadian dollars and all future costs and QALYs were discounted at a rate of 1.5% annually. Probabilistic and one-way sensitivity analyses were conducted. Results: The incremental cost-effectiveness ratios of TAVI using the SAPIEN 3 valve compared to surgery were $28,154 per QALY gained in intermediate risk patients and $17,237 per QALY gained in high-risk patients. The results of the probabilistic analyses indicated that at willingness-to-pay threshold of $50,000 per QALY gained, the probability of TAVI to be cost-effective was greater than 0.9 in both intermediate-risk and high-risk patients. Sensitivity analyses showed the results were most sensitive to the time horizon used. Conclusion: TAVI using the SAPIEN 3 valve is highly likely to be cost-effective in Canadian patients with severe aortic stenosis who are at intermediate and high surgical risk.
Pre-sowing magnetic field- induced changes in water relations and lipid peroxidation in cucumber under salinity stress

Overcoming salinity problems through increasing plant tolerance is a substantial strategy to increase crop production. A pot experiment was carried out to investigate the effect of salinity stress, pre-sowing magnetic fields and their combination on cucumber growth, water relations and lipid peroxidation. Seawater salinity (10%) enormously reduced the plant growth, relative water content (RWC), transpiration rate and water use efficiency (WUE), and increased partial osmotic pressure (POP), lipids peroxidation and membrane injury index. Root/shoot ratio was not affected by the salinity stress. Pre-sowing treatment with 50 mT (for 30 s or 30 min) and 100 mT (30 min) magnetic field enhanced plant growth, root/shoot ratio, RWC, transpiration rate and WUE under control and stress conditions in relation with the un-treated plants. These treatments appeared to reduce lipid peroxidation and membrane injury in cucumber under salinity stress. The effect of these magnetic treatments on POP was not regular. The combination treatment of those magnetic fields and salinity reduced the stress intensity index (SII) by about 25% in relation with salinity alone. Conversely, the application of 200 mT magnetic field for 30 min adversely affected the plant growth and water relations, and increased the SII, lipid peroxidation and membrane injury in cucumber under salinity stress. On many occasions, the effects of 100 mT for 30 min and 200 mT for 30 s were not significant.
Institutional Knowledge at Singapore Management University The necessities and luxuries of mate preferences: Testing the tradeoffs

The necessities and luxuries of mate preferences: Testing the tradeoffs. , Social exchange and evolutionary models of mate selection incorporate economic assumptions but have not considered a key distinction between necessities and luxuries. This distinction can clarify an apparent paradox: Status and attractiveness, though emphasized by many researchers, are not typically rated highly by research participants. Three studies supported the hypothesis that women and men first ensure sufficient levels of necessities in potential mates before considering many other characteristics rated as more important in prior surveys. In Studies 1 and 2, participants designed ideal long-term mates, purchasing various characteristics with 3 different budgets. Study 3 used a mate-screening paradigm and showed that people inquire 1st about hypothesized necessities. Physical attractiveness was a necessity to men, status and resources were necessities to women, and kindness and intelligence were necessities to both.
