Published: September 2019

AbstractBird-caused damages for overhead transmission lines become one of the main fault types of the power grid, which will affect the safety and reliability of power grid operation and usually bring huge economic losses. The effectiveness of existing bird repeller would deteriorate obviously due to the habituation of birds. Bird bioacoustic vocalization can elicit the avoidance behaviour of conspecific, which can delay the habituation process of birds to bird repeller. An intelligent bird repeller based on bird species variations was proposed. Based on birds’ appearance and vocalization respectively, two light weight networks were designed to identify the approaching bird species; according to the approaching bird species, the corresponding repellent modes were selected; the target was to improve the long-term effectiveness of the bird repeller, which is helpful to reduce the occurrence probability of bird-caused damages.

Published: September 2019

Abstract
Electric equipment image analysis has important meanings to power line inspection and repairment. This paper proposes an electric equipment image recognition method based on sparse representation. Considering the image collection is inevitably influenced by the light condition and noise corruption, this paper uses Bayesian compressive sensing algorithm to solve the sparse representation problem. The algorithm has good robustness to noises and interferences, which is suitable to handle the conditions in electrical equipment images. In the experiments, three electrical equipments, i.e., insulators, power transformers, and breakers, are classified and the accuracy reaches 93.56%. In addition, the robustness of the proposed method under noise corruption is also superior. All the results validate the effectiveness of the proposed method.

Abstract
In order to study the geochemical characteristics, origin and its hydrocarbon potential of the Upper Cretaceous marine source rocks in the Rio Muni Basin, Equatorial Guinea, 62 debris samples of the Anduak-1 well in the Rio Muni Basin were collected to Rock-Eval pyrolysis, whole rock organic petrology analysis. This study revealed that the OM in the upper Cretaceous source rock is early mature - mature, with moderate abundance and fair quality (mainly type II and III). The organic matter has a mixed marine–terrestrial origin and deposited in the marine environment, the plant debris were probably suffered from a long-distance transportation via fluvial or else forces. The main hydrocarbon generation phase of the type III kerogen was more duration than type II, initial hydrocarbon generation was earlier, and ending hydrocarbon generation time was late. Comprehensive studies demonstrated that it has a good hydrocarbon potential to the upper Cretaceous marine shale, and is an unneglectable hydrocarbon source rock.

Published: September 2019

Abstract
At present, most scholars use the mathematical model of FLUENT software to simulate migration and settlement process of dust, and tend to focus only on the graphical simulation results. For intermediate operation principle and process is not very clear, simulation results of commercial software will easily lead to distortion of simulation results. Based on this, the migration and settlement process of flowing dust in return airway of coal face has carried on the further analysis and research in this paper, and the main factors affecting the dust migration and settlement are analyzed comprehensively. At the same time, according to the law of mass conservation, a three-dimensional mathematical model of migration and settlement of flowing dust is established.

Published: September 2019

Abstract
Based on the principle of electrostatic induction, a dust detection device is designed in this paper, aiming at the problems of insensitive detection and slow movement of dust particles in the existing dust measuring devices. Its shape structure is improved on the basis of the existing straight pipe. The air inlet is arranged on the side of the cylindrical pipe wall so that the particles flow through the pipe in a double helix way and the diameter of the main pipe is changed to make the middle part of the pipe shrink. The 3D model of pipeline was established by gambit2.4 and simulated in Fluent6.3. In the improved device, the movement speed of dust particles increases. With the increase of velocity, the probability of friction and collision of dust particles in the side-entry tube is increased, and the induced charge is increased.Therefore, the improved device can effectively improve the accuracy of dust measurement under the condition of low concentration and small particle size.

Published: September 2019

Abstract
An essential oil from Cymbopogon nardus has many benefits, specifically in pharmaceutical, cosmetics and perfumery fields. However, extraction of Cymbopogon nardus produces abundant waste which usually left to decay naturally. The present study evaluated biogas potential from Cymbopogon nardus waste through anaerobic digestion method with rumen fluid as inoculum. The presence of methane which is the main gas that makes up the composition of biogas is verified by using GC-FID and Biogas Analyser. The waste was collected from the oil extraction of various part of Cymbopogon nardus plant. The experimental study on the extraction is important to identify the oil yield from various part of Cymbopogon nardus plant. The extraction was done through steam distillation with temperature varied from 40 °C to 100 °C. The comparison of oil yield from various part of the plant was done with an aid of GC-MS analysis. It was found that the leaf of Cymbopogon nardus contains most essential oil, which gives the highest oil yield about 1.5 % at 100 °C followed by the stem (0.3 %). The oil yield found in the plant flower was less than 0.3 % and none found in the root. Extraction at 100 °C resulted in higher oil yield compared to 40 °C, 60 °C and 80 °C. The citronellal content was the highest compound presents in the oil followed by geraniol. The average generation of biogas on the other hand were range from 0.4 ml/day to 12.5 ml/day. The F/I ratio which produced the highest volume of biogas is 10 (w/w).
Investigating the potential of meltblown polypropylene nanofiber membrane for desalination by membrane distillation
Authors: Chiam C K , Sarbatly R , Widyaparamitha S 
Published: September 2019

Abstract
A tubular nanofiber membrane module is developed and tested in the seawater desalination by using air-gap membrane desalination (AGMD). Meltblowing device is used to produce the nanofibers which are collected at a distance of 37 cm away from the tip of the spinneret. Results show that the flux varies almost constantly with the feed flow rates. The independence of the flux on the feed flow rates suggested that the meltblown nanofiber membrane is a dense membrane in which the volume of pores has been reduced and compacted significantly. The flux increases exponentially with the feed temperatures which obeys the Arrhenius relation. The quality of permeate is essentially improved by using the compacted nanofiber membrane. The rejection of the dissolved salts is more than 99.3%, in which the conductivity values of permeate ranged between 8 and 50 μS/cm.

Published: September 2019

Abstract
This study presents the tool life optimization of carbide coated ball nose milling inserts using high-speed milling Inconel 718 under cryogenic CO2 environment. A total of 29 experiments were conducted based on Box-Behnken Response Surface Methodology using the 4 factors; cutting speed (Vc: 120-140 m/min), feed rate (Fz: 0.15-0.25 mm/tooth), axial depth of cut (ap: 0.3-0.7 mm), and radial depth of cut (ae: 0.2-0.6 mm) at three levels each. By using ANOVA, it was found that all factors have significant effects on tool life. However, the feed rate shows its highest influence on the tool performance where the tool life can be lengthened by reducing the feed rate values. After that, the relevant influencing parameters on tool life were derived in the form of mathematical model which was then used to predict the response within the predetermined parameters. With an average error of 8.2% between the predicted and actual tool life, it confirms the adequacy of the model in this research. ANOVA also suggests a tool life of 23.40 min could be obtained at optimized parameters of; Vc: 120.06 m/min, Fz: 0.15 mm/tooth, ap: 0.66 mm and ae: 0.53 mm under cryogenic CO2 condition.

Published: September 2019

Abstract

Objective
This study examines the correlation between age of immigration for Spanish speakers in the USA and their performance on the Córdoba Naming Test (CNT), a confrontation naming test designed to be multicultural. We predicted that those who immigrated at a later age, whom we expect to have more years of education in their native language, will perform better on the CNT.

Method
The study used the CNT with a sample of 44 Spanish-speakers from the United States. We worked with participants with no prior history of medical complications, such as damage to the central nervous system, drug use, or excessive alcohol use. 21 male and 23 female participants were recruited. The age of participants ranged from 20 to 89 years old and education ranged from 0 to 22 years of schooling (either in the United States or in their native country). The variables of focus are the age of immigration into the United States (when participants migrated into the US) and their test performance on the CNT (total score of correct responses).

Results
Our results indicate a statistically significant positive correlation between age of immigration and performance on the CNT, (r(44)) = .357, p = .019). Conclusions: The overall trend of the data suggested that older age at immigration was indeed associated with better performance on the CNT, thus highlighting the importance of language and acculturation issues when being assessed with neuropsychological or cognitive testing.

Conclusions

Authors: Culbertson Eric J , Felder-Scott Christina , Deva Anand K , Greenberg David E , Adams William P 
Published: September 2019

Abstract

Background
Specific antimicrobial breast pocket irrigations have been proven over the past 20 years to reduce the incidence of capsular contracture by a factor of 10, and the emergence of breast implant–associated anaplastic large cell lymphoma (BIA-ALCL) and its link to bacteria/technique has created renewed interest in different antimicrobial breast pocket preparation agents. Our previous studies have identified that both Betadine-containing and non-Betadine-containing antimicrobial irrigations provide excellent broad-spectrum bacterial coverage. The current science of BIA-ALCL has implicated the Gram-negative microbiome as a key in pathogenesis.

Objectives
The aim of this study was to revisit the antimicrobial effectiveness of clinically utilized Betadine and non-Betadine solutions, along with other antimicrobial agents that have not yet been tested, against multiple organisms, including additional common Gram-negative bacteria associated with chronic breast implant infections/inflammation.

Methods
Current and new antimicrobial breast irrigations were tested via standard techniques for bactericidal activity against multiple Gram-positive and Gram-negative strains. Test results are detailed and clinical recommendations for current antimicrobial irrigations are provided.

Results
Betadine-containing irrigations were found to be superior according to the testing performed.

Conclusions
There are quite few misconceptions with regard to antimicrobial breast pocket irrigation. These are discussed and final evidence-based recommendations for practice are given.

Published: September 2019

Abstract

Background
Antibiotic stewardship is challenging in hematological malignancy patients.

Methods
We performed a quasiexperimental implementation study of 2 antimicrobial stewardship interventions in a hematological malignancy unit: monthly antibiotic cycling for febrile neutropenia that included cefepime (± metronidazole) and piperacillin-tazobactam and a clinical prediction rule to guide anti-vancomycin-resistant Enterococcus faecium (VRE) therapy. We used interrupted time-series analysis to compare antibiotic use and logistic regression in order to adjust observed unit-level changes in resistant infections by background community rates.

Results
A total of 2434 admissions spanning 3 years pre- and 2 years postimplementation were included. Unadjusted carbapenem and daptomycin use decreased significantly. In interrupted time-series analysis, carbapenem use decreased by −230 days of therapy (DOT)/1000 patient-days (95% confidence interval [CI], −290 to −180; P &lt; .001). Both VRE colonization (odds ratio [OR], 0.64; 95% CI, 0.51 to 0.81; P &lt; .001) and infection (OR, 0.41; 95% CI, 0.2 to 0.9; P = .02) decreased after implementation. This shift may have had a greater effect on daptomycin prescribing (−160 DOT/1000 patient-days; 95% CI, −200 to −120; P &lt; .001) than did the VRE clinical prediction score (−30 DOT/1000 patient-days; 95% CI, −50 to 0; P = .08). Also, 46.2% of Pseudomonas aeruginosa isolates were carbapenem-resistant preimplementation compared with 25.0% postimplementation (P = .32). Unit-level changes in methicillin-resistant Staphylococcus aureus and extended-spectrum beta lactamase (ESBL) incidence were explained by background community-level trends, while changes in AmpC ESBL and VRE appeared to be independent. The program was not associated with increased mortality.

Conclusions
An antibiotic cycling-based strategy for febrile neutropenia effectively reduced carbapenem use, which may have resulted in decreased VRE colonization and infection and perhaps, in turn, decreased daptomycin prescribing.
The implications of persistent (and permanent) engagement in cyberspace
Authors: Healey Jason 
Published: September 2019

Abstract
The USA is in the midst of its most resounding policy shift on cyber conflict with profound implications for national security and the future of the Internet. The US Department of Defense (DoD) cyber strategy concludes that since US cyber forces are in “persistent engagement” with adversaries, then it is an imperative for them to “defend forward” to “continuously contest” them. The implicit prediction is that adversaries will become less effective, forced to expend more resources on defense and rebuild capabilities and infrastructure. John Bolton, the national security advisor, has boasted of a new policy to use offensive cyber operations to impose costs on adversaries and create the frameworks of deterrence. Over time, proponents suggest, these policies will be stabilizing as adversaries engage over repeated engagements in “tacit bargaining” of what is and is not acceptable leading to “more stable expectations of acceptable and unacceptable behavior”. This article advances existing research by including a deeper discussion the academic and policy background on active defense and cyber deterrence, discussing the implied causal chain of “persistent- engagement stability theory,” and analyzing potential risks, especially specific feedback loops which may amplify or dampen cyber conflict. It concludes with specific policy solutions to help mitigate these risks and a suggestion for a broader theory, “stability-enhancing engagement theory.”
