Published: November 2019

ObjectiveThe aim of this study was to identify the challenges anticipated by clinical staff in two Melbourne health services in relation to the legalisation of voluntary assisted dying in Victoria, Australia.
MethodsA qualitative approach was used to investigate perceived challenges for clinicians. Data were collected after the law had passed but before the start date for voluntary assisted dying in Victoria. This work is part of a larger mixed-methods anonymous online survey about Victorian clinicians’ views on voluntary assisted dying. Five open-ended questions were included in order to gather text data from a large number of clinicians in diverse roles. Participants included medical, nursing and allied health staff from two services, one a metropolitan tertiary referral health service (Service 1) and the other a major metropolitan health service (Service 2). The data were analysed thematically using qualitative description.
ResultsIn all, 1086 staff provided responses to one or more qualitative questions: 774 from Service 1 and 312 from Service 2. Clinicians anticipated a range of challenges, which included burdens for staff, such as emotional toll, workload and increased conflict with colleagues, patients and families. Challenges regarding organisational culture, the logistics of delivering voluntary assisted dying under the specific Victorian law and how voluntary assisted dying would fit within the hospital’s overall work were also raised.
ConclusionsThe legalisation of voluntary assisted dying is anticipated to create a range of challenges for all types of clinicians in the hospital setting. Clinicians identified challenges both at the individual and system levels.
What is known about the topic?Voluntary assisted dying became legal in Victoria on 19 June 2019 under the Voluntary Assisted Dying Act 2017. However there has been little Victorian data to inform implementation.
What does this paper add?Victorian hospital clinicians anticipate challenges at the individual and system levels, and across all clinical disciplines. These challenges include increased conflict, emotional burden and workload. Clinicians report concerns about organisational culture, the logistics of delivering voluntary assisted dying under the specific Victorian law and effects on hospitals’ overall work.
What are the implications for practitioners?Careful attention to the breadth of staff affected, alongside appropriate resourcing, will be needed to support clinicians in the context of this legislative change.

Published: November 2019

Temperate Australian saltmarshes, including those in the southern island state of Tasmania, are considered to be a threatened ecological community under Australian federal legislation. There is a need to improve our understanding of the ecological components, functional relationships and threatening processes of Tasmanian coastal saltmarshes and distil research priorities that could assist recovery actions. A semisystematic review of the literature on Tasmanian coastal saltmarshes supported by expert local knowledge identified 75 studies from 1947 to 2019. Existing understanding pertains to saltmarsh plants, soils, invertebrates and human impacts with ongoing studies currently adding to this knowledge base. Several knowledge gaps remain, and the present review recommends six key priority areas for research: (1) citizen science–organised inventory of (initially) saltmarsh birds, plants and human impacts with the potential for expansion of datasets; (2) use of saltmarsh by marine transient species including fish and decapods; (3) use of saltmarsh by, and interactions with, native and introduced mammals; (4) invertebrates and their interactions with predators (e.g. birds, fish) and prey (e.g. insects, plants, detritus); (5) historic saltmarsh loss and priority areas for conservation; (6) monitoring changes to saltmarsh due to both localised human impacts (e.g. grazing, eutrophication, destruction) and global change factors (e.g. climate change, sea-level rise). Addressing these research priorities will help in developing a better understanding of the ecological character of Tasmanian coastal saltmarshes and improve their conservation management.
Quantitative evaluation on the challenges and opportunities in the recruitment of young Black men who have sex with men for sexual health research in the southern US
Authors: Dodson C. Kelsie , Jackson D'Netria , Muzny Christina A. , Eaton Ellen F.
Published: November 2019

Background
Young Black men who have sex with men (YBMSM) in the Deep South are at increased risk of sexually transmissible infections (STIs) and HIV. The present two-phase study evaluated the recruitment of YBMSM, both HIV infected and uninfected, for a sexual health study in Birmingham (AL, USA) from 2017 to 2019 and explored alternative patient-centred recruitment methods. Methods: In Phase 1, YBMSM were recruited to participate in focus groups related to STI testing. To recruit participants, flyers were displayed in businesses, clinics and lesbian, gay, bisexual and transgender (LGBT)-friendly organisations. In addition, research staff at an HIV clinic referred participants and a recruiter attended community events. In Phase 2, YB men were asked, in an electronic survey, ‘What is the best way to recruit young, Black men for surveys about sexual health?’ and ‘If you selected ‘social media’, which social media sites or ‘apps’ do you think are best to recruit young, Black men?’. Results: In Phase 1, 38 YBMSM participated in focus groups. Twelve (32%) were recruited by referral, 9 (24%) were recruited from an HIV clinic and 11 (29%) were recruited from an LGBT organisation. The recruiter was unable to recruit any participants. In Phase 2, 55 YBMSM completed the electronic survey. Twenty-six (48%) selected social media as the best way to recruit young Black men for surveys about sexual health, and their suggested platforms included Instagram, Facebook, Twitter, Snapchat, Kik and dating apps. Seventeen (31%) selected ‘Having young gay black men recruit from their friends and acquaintances’ as the ideal recruitment strategy. Conclusion: Challenges persist when recruiting YBMSM for sexual health research. Social media may provide better access to this vulnerable population.
A locomotor assay reveals deficits in heterozygous Parkinson’s disease model and proprioceptive mutants in adult
Drosophila
Authors: Aggarwal Aman , Reichert Heinrich , VijayRaghavan K.
Published: November 2019

Severe locomotor impairment is a common phenotype of neurodegenerative disorders such as Parkinson’s disease (PD).
Drosophila
models of PD, studied for more than a decade, have helped in understanding the interaction between various genetic factors, such as
parkin
and PINK1, in this disease. To characterize locomotor behavioral phenotypes for these genes, fly climbing assays have been widely used. While these simple current assays for locomotor defects in
Drosophila
mutants measure some locomotor phenotypes well, it is possible that detection of subtle changes in behavior is important to understand the manifestation of locomotor disorders. We introduce a climbing behavior assay which provides such fine-scale behavioral data and tests this proposition for the
Drosophila
model. We use this inexpensive, fully automated assay to quantitatively characterize the climbing behavior at high parametric resolution in 3 contexts. First, we characterize wild-type flies and uncover a hitherto unknown sexual dimorphism in climbing behavior. Second, we study climbing behavior of heterozygous mutants of genes implicated in the fly PD model and reveal previously unreported prominent locomotor defects in some of these heterozygous fly lines. Finally, we study locomotor defects in a homozygous proprioceptory mutation (
Trp-γ

1

) known to affect fine motor control in
Drosophila
. Moreover, we identify aberrant geotactic behavior in
Trp-γ

1

mutants, thereby opening up a finer assay for geotaxis and its genetic basis. Our assay is therefore a cost-effective, general tool for measuring locomotor behaviors of wild-type and mutant flies in fine detail and can reveal subtle motor defects.
Vitamin D binding protein is required to utilize skin-generated vitamin D
Authors: Duchow Elizabeth G. , Cooke Nancy E. , Seeman Jeremy , Plum Lori A. , DeLuca Hector F.
Published: November 2019

Significance

The primary source of vitamin D in man is production in the skin following exposure to sunlight or artificially produced ultraviolet (UV) light. Despite the importance of this source, the mechanisms surrounding the transport of cutaneous vitamin D into the circulation have not been clearly defined. We have examined the vitamin D response to UVB in mutant mice lacking vitamin D binding protein (DBP). We have shown that in the absence of DBP, UVB does not correct vitamin D deficiency. Further, injection of small amounts of recombinant DBP to DBP
−/−
mice restores the response to vitamin D produced in skin. These results demonstrate a requirement for DBP in the utilization of vitamin D produced in the epidermis by UV light.
From abugida to alphabet in Konso, Ethiopia

Published: November 2019

This study examines the interplay between phonological awareness and orthography in Konso, a Cushitic language in
Southwest Ethiopia. Thirty-two adults reading the Konso abugida but with minimal exposure to alphabetic literacy completed an
orally administered phoneme deletion task. The responses were then examined using the minimal edit distance
hypothesis (Wali, Sproat, Padakannaya & Bhuvaneshwari, 2009) as a
framework for the analysis. The results suggest that the difficulty of a deletion was related to the way the phoneme was
represented in the Konso abugida. Content-based error analysis of the incorrect responses gave indications of how Konso abugida
readers’ processing of sounds is linked to Konso abugida sound-symbol relationships.

The Konso language community is undergoing a change in their writing system from abugida to alphabetic writing. As
abugida symbols primarily denote consonant-vowel sequences, the change requires learning new sound-symbol mappings. By examining
Konso abugida readers’ phonemic awareness the study contributes to developing transfer literacy teaching methods from abugida to
alphabetic writing in Konso and elsewhere.

Authors: Khater Mostafa M. A. , Lu Dian-Chen , Attia Raghda A. M. , Inç Mustafa
Published: November 2019

This article studies the performance of analytical, semi-analytical and numerical scheme on the complex nonlinear Schrödinger (NLS) equation. The generalized auxiliary equation method is surveyed to get the explicit wave solutions that are used to examine the semi-analytical and numerical solutions that are obtained by the Adomian decomposition method, and B-spline schemes (cubic, quantic, and septic). The complex NLS equation relates to many physical phenomena in different branches of science like a quantum state, fiber optics, and water waves. It describes the evolution of slowly varying packets of quasi-monochromatic waves, wave propagation, and the envelope of modulated wave groups, respectively. Moreover, it relates to Bose-Einstein condensates which is a state of matter of a dilute gas of bosons cooled to temperatures very close to absolute zero. Some of the obtained solutions are studied under specific conditions on the parameters to constitute and study the dynamical behavior of this model in two and three-dimensional.
On the Boundary Condition and Related Instability in the Smoothed Particle Hydrodynamics
Authors: Ye Chong , Mota Philipe , Li Jin , Lin Kai , Qian Wei-Liang
Published: November 2019

In this work, we explore various relevant aspects of the Smoothed Particle Hydrodynamics regarding Burger’s equation. The stability, precision, and efficiency of the algorithm are investigated in terms of different implementations. In particular, we argue that the boundary condition plays an essential role in the stability of numerical implementation. Besides, the issue is shown to be closely associated with the initial particle distribution and the interpolation scheme. Among others, we introduce an interpolation scheme termed symmetrized finite particle method. The main advantage of the scheme is that its implementation does not involve any derivative of the kernel function. Concerning the equation of motion, the calculations are carried out using two distinct scenarios, where the particles are chosen to be either stationary or dynamically evolved. The obtained results are compared with those obtained by using the standard finite difference method for spatial derivatives. Our numerical results indicate subtle differences between different schemes regarding the choice of boundary condition. In particular, a novel type of instability is observed where the regular distribution is compromised as the particles start to traverse each other. Implications and further discussions of the present study are also addressed.
Scalar or Vector Tetraquark State Candidate: Zc(4100)*
Authors: Wang Zhi-Gang
Published: November 2019

In this article, we separate the vector and axialvector components of the tensor diquark operators explicitly, construct the axialvector-axialvector type and vector-vector type scalar tetraquark currents and scalar-tensor type tensor tetraquark current to study the scalar, vector and axialvector tetraquark states with the QCD sum rules in a consistent way. The present calculations do not favor assigning the Zc
(4100) to be a scalar or vector tetraquark state. If the Zc
(4100) is a scalar tetraquark state without mixing effects, it should have a mass about 3.9 GeV or 4.0 GeV rather than 4.1 GeV; on the other hand, if the Zc
(4100) is a vector tetraquark state, it should have a mass about 4.2 GeV rather than 4.1 GeV. However, if we introduce mixing, a mixing scalar tetraquark state can have a mass about 4.1 GeV. As a byproduct, we obtain an axialvector tetraquark candidate for the Zc
(4020).
Analysis of shape optimization problems for unsteady fluid-structure interaction
Authors: Haubner Johannes , Ulbrich Michael , Ulbrich Stefan
Published: November 2019

Shape optimization via the method of mappings is investigated for unsteady fluid-structure interaction (FSI) problems that couple the Navier–Stokes equations and the Lamé system. Building on recent existence and regularity theory we prove Fréchet differentiability results for the state with respect to domain variations. These results form an analytical foundation for optimization und inverse problems governed by FSI systems. Our analysis develops a general framework for deriving local-in-time continuity and differentiability results for parameter dependent nonlinear systems of partial differential equations. The main part of the paper is devoted to conducting this analysis for the FSI problem, transformed to a shape reference domain. The underlying shape transformation—actually we work with the corresponding shape displacement instead—represents the shape and the main result proves the Fréchet differentiability of the solution of the FSI system with respect to the shape transformation.
There is no general connection between the quantum speed limit and non-Markovianity
Authors: Teittinen J , Lyyra H , Maniscalco S
Published: November 2019

The quantum speed limit (QSL) sets a bound on the minimum time required for a quantum system to evolve between two states. For open quantum systems this quantity depends on the dynamical map describing the time evolution in presence of the environment, on the evolution time τ, and on the initial state of the system. We consider a general single qubit open dynamics and show that there is no simple relationship between memory effects and the tightness of the QSL bound. We prove that only for specific classes of dynamical evolutions and initial states, there exists a link between non-Markovianity and the QSL. Our results shed light on the connection between information back-flow between system and environment and the speed of quantum evolution.

Published: November 2019

The traditional face recognition technology is more complicated for the extraction of facial image features and the selection of classifiers, and the recognition rate is not high. With the continuous maturity of the convolutional neural network from handwritten digit recognition to face recognition, A face recognition algorithm that tests CNN using the Python+Keras framework. The method mainly involves two aspects. One is to observe the influence on the network by changing the number of neurons in the hidden layer; the other is to observe the influence on the network by changing the number of feature maps of the convolutional layer 1 and the convolutional layer 2. The best CNN model is 36-76-1024 through multiple sets of experimental tests. The model can automatically extract facial image features and classify them. Using adam optimizer and softmax classifier for face recognition can make training faster convergence and more. Effectively improve accuracy and use the Dropout method to avoid overfitting. The experimental results show that the recognition rate of the CNN model on the olivettifaces face database is 97.5%. When the optimal CNN model is used, the average recognition rate is close to 100%, which verifies the validity and accuracy of the algorithm and model.

Authors: Valdes M , Ardila Marín J G , Holguin M
Published: November 2019

Heat exchangers are fundamental for energy plants and the operation of industrial processes. As a result, active and passive techniques are needed to increase heat transfer and develop efficient and reliable designs. The design of heat exchangers has been based on iterative methods that require experimentation to be validated. These circumstances, added to the development of powerful microprocessors, promote the use of numerical methods to study flow distribution and pressure drop, as well as thermal analyses applying different turbulence models and several coupling speed-pressure schemes. This paper examines flow development through curved and twisted tube heat exchanger by means of a computational fluid dynamics numerical model developed in ANSYS® in order to establish the minimum length required to infer conclusions for the complete exchanger. This work tries to reduce the computational cost while maintaining the balance between desired accuracy and available computational resources. Finally, this study shows that the flow can be considered fully developed after it has traveled 360° inside the helix; after that point, secondary flows and re-circulation regions improve the heat transference in these devices can be verified.

Published: November 2019

Analysis of the existing «megascience» projects, such as the Joint Institute for Nuclear Research (JINR) in Dubna (the Russian Federation) and the European Spallation Source (ESS) in Lund (the Kingdom of Sweden) allows to conclude that one of the most suitable legal forms for the ICNR PIK would be an international intergovernmental organization (IGO). Legal status of the IGO would provide an international participation in the functioning of the ICNR PIK within the territory of the Russian Federation on the grounds of member or observer status or conclusion of bilateral and multilateral agreements on specific science programs and research studies. To conclude, the IGO is the most suitable organizational and legal form for the ICNR PIK. The establishment of the ICNR PIK will contribute to further integration of the Russian science in the global scientific research community and will expand the scope of cooperation of the Russian Federation in the international arena.
On the prospects for an integrated approach to the legal regulation of scientific projects of the “megascience” class
Authors: Karandaev I Y
Published: November 2019

Scientific projects of the “megascience” class are large-scale scientific facilities that require the attraction of significant human, material and financial resources. Given these features, they are most often realized by sharing costs between several states interested in implementing projects. The involvement of foreign participants in Russian scientific projects of the “megascience” class leads to the need to comply with the requirements of the legislation of the Russian Federation, which do not take into account the specifics of projects of the “megascience” class, in particular the organization of the stay of foreign scientists, engineers, their labor activities, import and export of scientific equipment, personnel training and others. In this regard, the report considers options for an integrated approach to the legal regulation of scientific projects of the “megascience” class in order to improve their implementation mechanisms and make them more attractive to foreign participation.

Published: November 2019

Chicken feather meals constitutes 80-85% protein, the main component being betakeratin, a fibrous and insoluble structural protein extensively cross linked by disulfide bonds. The keratins can not be absorbed directly in the digestive system, therefore a processing technique is required to make it more absorbable. Processing technique can be fermentation by microorganism Bacillus subtilis to degrade keratin by secretion of keratinase. The aim of this study was to examine fermentation of chicken feather meal with B. subtilis to improve the quality of fish feed ingredients. The treatments were: no-fermented; fermentation of chicken feather meals: 6, 8, 10, 12 and 14 ml inoculum fermentation using B. subtilis, respectively for chicken feather meal as much as 2 g. The results showed that the processing fermentation with 10 ml inoculum B. subtilis gives the best results in the highest keratinase activity (273.33 U/ml), increased the protein content of chicken feather meals (74.16 to 85.20%), but decreated of lipid content (2.44 to 1.42%) and carbohydrate content (7.86 to 2.05%) with a change in the physical properties of white -yellow (color), soft (texture), and less typical sting (smell).

Authors: Rizal M , Amarullah T , Rahma E A
Published: November 2019

The aim of this study is to know the national fish logistics system as an effort to support sustainable food security. One of the potential that Indonesia has is capturing fisheries which reached 6.4 million tons of fish per year. However, it has not been managed properly in an effort to support food security. Besides, the fish production in certain fishing ports often excess supply and limited of fish in several other fishing ports. This will lead to practices that suppress fish prices when overproduction, even fishermen/cultivators dispose of their products to maintain price stability, without taking into account the sustainability aspects. This issue can be resolved immediately with a study that leads to SLIN, but having a commitment to support this business has developed the concept of connectivity between regions. the study was taken in 10 fishing ports at Simeulue Island which used type D. The result showed that from the aspect of development goals, it is necessary to provide supply continuously, to utilize the potential optimally and to coordinate the integration of fish availability in production centers and/or collection centers or distribution center, obstacle elements include; lack of PP facilities and infrastructure, no integration between PPs, and lack of diversification of HT and products.

Published: November 2019

Phytoestrogens, one of the biochemicals derived from turmeric plant, possessed a structural similarities to estradiol, which may possibly exert similar activities in stimulating liver to synthesize vitellogenin. This vitellogenesis is important part in follicular development. This study aimed to evaluate the effects of turmeric flour (Curcuma longa) on the fertilization, hatching and survival rate of Serukan fish (Osteochilus vittatus). Completely randomized design consisting of four treatments and three replications were used in this study. A total of 10 matured females were fed with turmeric flour for eight weeks at dose of 0, 0.25, 0.5, and 0.75 gr per kg feed. The results showed that turmeric flour could improve the survival rate of Serukan fish (Sig < 0.05). Specifically, administration of turmeric flour at level of 0.5 gr per kg feed could increase survival rate up to 95.78 ± 2.0 %, being much higher than control reaching up to 55.78 ± 1.9%. However, the fertilization and hatching rate seemed to be unaltered by the treatments (Sig>0.05). This study suggested that turmeric flour could significantly affect the survival of the early life of serukan fish.

The Indonesian Minister of Marine and Fisheries Regulations has given a prospect for domestic fishing vessels and Merauke as the stay over fishing port. This study found that in Merauke the capacity of cold storage was only 2,250 tons; the shortage of ice supply for fishing remains occurred; most of the fishing fleets were not equipped with freezer and; the fish-processing unit did not exist. As a consequence, 13.42% - 51.5% of fishes were thrown away to the sea after taking the swim bladder of fish (fish maw). Data and information on fisheries were collected from 23 April 2019 to 3 May 2019 in Merauke. The supply chain approach was used for policy intervention to improve the fishing business. The objective of this study was to analyze the phenomenon of fishery business in Merauke. The main conclusion of the analysis show, Merauke become a landing place for fish maw’s fishing fleets from the Arafura Sea. This study recommended that there must be an investor to organize a 100 tons ice factory as a supplier for fishing vessels. Merauke might be promoted as the center for pet food industries by using discarded fish to fill domestic market demand. Promote local traders to follow domestic and international fish trade exhibition to prepare Merauke as the business center of fish maw.

This research focuses on the granulometric analysis of coastal sediments zone in Lampuuk-Lhoknga Beach, Aceh Province. A total of 11 stations along Lampuuk-Lhoknga Beach located in swash zone are determined as locations for data collection. The sample sediment was collected in November 2018. The selected station was divided into two zones namely the upper swash zone (USZ) and lower swash zone (LSZ). The sampling technique was carried out by using a vertical coring method in order to get a sediment layer with a thickness of 5 cm from the surface. Each sediment sample was wetly sieved to obtain a weight distribution percentage based on the sieve size. Sediment statistical analysis of each sample was based on the Folk and Ward Method. The results of the study show that the average conditions of Lampuuk sediment in the upper swash zone are medium sand; Moderately Well Sorted; Symmetrical; and Mesokurtic. In Addition, at the lower swash zone is found a medium sand; Moderately Sorted; Coarse Skewed; and mesokurtic. The beach morphological diversity has resulted in a variation of statistical parameters along the shoreline at Lampuuk and Lhoknga.

The beach is a boundary between the ocean and land changes with time due to erosion and sedimentation events. The study of beach changes aims to understand the condition of the coast towards the factors that influence it, such as wave height, wave angle of arrival, beach area, depth, and groin. The study used synthetic beach conditions data. Furthermore, changes in shoreline caused were modelled with one-line models using numerical method solutions. Modeling results show that shoreline changes increase with time, and are strongly influenced by wave height, wave angle and the distance of waves breaking to the beach. Changes in the coastline are also influenced by the location of the beach structures, the structures of the beach that are parallel to the coast will provide better results to prevent the coast than the structure located off the coast.

Pedih (Tor douronensis) is a freshwater fish that live in mountainous areas and swift rivers in the interior of Aceh. The aimed of this research was to analyze the dosage of PMSG+AD hormone orally for the gonadal maturation of pedih (Tor dauronensis). This research was conducted at technical implementation unit of fish breeding center Lukup Badak, Pegasing district, Aceh Tengah on Febuary to March 2018. The method used was Completely Randomized Design (CRD) with 4 level of treatment and three replications: 0 ml/kg feed, 0.3 ml/kg feed, 0.5 ml/kg feed and 0.7 ml/kg feed. The result of ANOVA test showed that different dosage of PMSG+AD hormone orally showed significant effect on the weight of broodstock, relative weight, gonad maturations index, eggs diameter, and relative eggs diameter. The result of Duncan test showed that the best dosage was found 0.7 ml/kg feed, but this treatment was not significantly different with the dosage of 0.5 ml/kg feed.

Kampung Nambo is one of the densest kampung in South Tangerang, Banten Province, Indonesia. This kampung has direct boundary to the state-owned Landfill, the Cipeucang Landfill. Apart of the mountainous waste panoramas and the continuous odours that can be seen and smelled all day from the kampung, this kampung has beautiful landscape scenery and many potential to develop further towards a livable kampung. The inhabitants in Kampung Nambo are witnessing environmental degradations happened in their area, including on its spring water quality that serve as one of the clean water sources for the community. This paper describes about community engagement program activities in one area in Kampung Nambo especially in region 03/04. The program aims to facilitate the community in finding ways to decrease the environmental degradation. One of the interventions was done trough sanitation aspect. The program found 7-8% of the community still apply open access from their toilets to the river. It gets the area and river even more polluted. This paper described about the action of reducing environmental degradation due to above conditions by cutting the critical contamination points. As further intervention, a new location for wastewater treatment plant was identified.

This study intends to be able to find out the results of a digital map format shape file using the Open Street Map tool in ArcGIS, to be able to produce a digital map is done by extracting data on the Open Street Map. How to extract is done by installing an additional ArcGIS Editor program for Open Street Map in ArcGIS 10.3 and extracting it so that it produces a digital map in the geodatabase format, then converts it to the shape file format using the conversion tool. There are two conditions in the selected area, namely the city area to represent densely populated villages and vice versa, as well as the mapped area coverage, both broad and narrow. The digital map of shape files produced consists of points, polylines, and polygons. Coverage of areas with a scale smaller than 1: 10,000 for urban areas cannot be extracted, whereas in rural areas it can. But on a scale of 1: 5,000 you can. Thus besides the area of building density also determines whether or not the area is extracted (mapped).
