Plasmon resonance in CVD graphene-silver nanoparticle composites
Authors: Boyko E V , Kostogrud I A 
Published: December 2019

Abstract
Investigation results on the morphology and optical properties of polymer-graphene composites with silver nanoparticles deposited by pulsed laser ablation are presented. Graphene was obtained by the CVD method and transferred to PET/EVA polymer through thermal pressing. It has been established that with an increase in the thickness of deposited silver film, a transition from bimodal distribution of particles to formation of elongated rectangular nanostructures is observed. A similar phenomenon can be explained by accumulation of deposited silver particles along the boundaries of adjacent graphene crystallites. It is experimentally shown that the degree of plasmon absorption depends strongly on the mass-average thickness of the deposited metal coating and size of nanoparticles. Deepening of the peak of plasmon absorption simultaneously with a general decrease in sample transparency occurs when the film thickness is changed up to 6 nm. A further increase in thickness does not affect the intensity of plasmon absorption and scattering, but leads to a general decrease in transparency of the polymer-graphene-silver composite. It is shown that the highest degree of radiation attenuation is in the wavelength range from 400 to 600 nm.

Authors: Demin N A , Fedoseev A V 
Published: December 2019

Abstract
The self-consistent model for the positive column of a glow discharge is presented. The model is based on the simultaneous solution of the nonlocal Boltzmann equation for electron energy distribution function, continuity equation for ions and Poisson equation for electric field. Calculations were performed for a discharge tube similar to the Plasma Kristall-4 experiments for plasma forming gas helium for the range of pressures of 20-70 Pa and the range of discharge currents of 0.5-2.5 mA. Axial electric field strength, electron temperature and electron density dependences on the discharge current and the gas pressure are obtained. The results show a good correlation with the data obtained by the other authors.

Abstract
For the purpose of simulation of diamond-growth processes, the comparison of reacting gas flows modelled in a heated cylindrical channel has been performed by two different approaches: DSMC method and solution of Navier-Stokes equations. The impact of the channel length on the degree of hydrogen and methane dissociation in the gas mixture has been analyzed. The obtained data were compared with the experimental data.
Gas molecules could be transferred through the lipid bilayer by kinks-solitons
Authors: Mokrushnikov P V 
Published: December 2019

Abstract
A hypothesis on the transfer of gas molecules through erythrocyte membrane by kink-solitons is discussed. Earlier it was supposed that gas molecules could be transferred through the lipid bilayer by kinks. It is accepted that kinks can emerge due to thermal vibrations. However, it remained unclear how the chaotic thermal vibrations can generate kinks moving along a hydrocarbon chain. According to the proposed hypothesis, kink-solitons appear under the simultaneous action of compressive lateral mechanical stresses and straining longitudinal mechanical stresses in the membrane. Compressive lateral stresses should have a certain value. This model explains a sharp increase in gas permeability of the membrane that occurs when erythrocyte passes through a microcapillary network, which is accompanied by substantially increased compressive lateral mechanical stresses.
Non-local character of negative glow emission of a low pressure glow discharge
Authors: Pinaev V A 
Published: December 2019

Abstract
A beam electron energy distribution function (BEEDF) in the cathode regions of a low-pressure glow discharge in helium was calculated using a Monte-Carlo technique. Based on the obtained data on the distribution of the BEEDF along the discharge length, the excitation rate of the 1s3p
1P level was calculated assuming that the direct electron excitation of helium atoms from the ground state takes place. It is shown that the calculated excitation rates of the 1s3p
1P level along discharge path are in good agreement with the experimentally measured emission distribution of the 501.6 nm helium spectral line.

Published: December 2019

Abstract
The thermal diffusivity (a), linear thermal expansion coefficient (α), isobaric heat capacity (Cp
) and phase transition enthalpy (ΔH) of Inconel 718 superalloy were determined by laser flash method, dilatometric method and differential scanning calorimetry in the temperature range of 298–1375…1473 К. The thermal conductivity (λ) has been calculated from the measurement results. The estimated errors of the obtained data were 2–5%, 3–5%, 2–3% and (1.5–2)×10−7 K−1 for a, λ, Cp
and α, respectively. The approximation equations and a table of reference values for the studied properties have been obtained.
Molecular simulation of viscosity of nanofluids based on water with metal particles
Authors: Krasnolutskii S L , Belkin A A , Lezhnev E V 
Published: December 2019

Abstract
Shear viscosity coefficient of water-based nanofluids with copper particles is simulated with the molecular dynamics method. The interaction of water molecules with each other was modeled with Lennard-Jones potential. The viscosity coefficient was calculated on the basis of the fluctuation-dissipation theorem by the Green–Kubo formula. The selection of parameters of the potential corresponding to the experimental values of water viscosity and density at a given temperature of 25°C at the atmospheric pressure is performed. Rudyak–Krasnolutskii (RK) and Rudyak–Krasnolutskii–Ivanov (RKI) potentials described interaction between nanoparticles and water molecules and nanoparticles with each other, respectively. Diameters of copper nanoparticles used were 2 and 4 nm. Volume concentration of the nanoparticles varied from 1% to 5%. It is shown that the viscosity of the nanofluids exceeds significantly the viscosity of suspensions with macroscopic particles and increases with a decrease in the size of nanoparticles at a fixed volume concentration. The paper also presents the calculation data of pair distribution functions for pure water and nanofluid. It is shown that the water near the nanoparticle is much more structured than in the free volume. This large ordering in the nanofluids is one of the key factors of their higher viscosity compared to pure water.

Authors: Stankus S V , Savchenko I V , Khairulin A R , Yatsuk O S 
Published: December 2019

Abstract
The enthalpy of solid and liquid Cs72.9Bi27.1 alloy was measured by a mixing method on a massive isothermal drop calorimeter in the temperature range of 432–1177 K. Approximation equations were obtained. The isobaric heat capacity and enthalpy change on melting were determined. The estimated errors for enthalpy and heat capacity were 0.5 and 1.5%, respectively. A significant positive deviation of the caloric properties from the additivity values was established. Tables of recommended values of caloric properties over the range from 298.15 K to 1175 K were developed.

Published: December 2019

Abstract
This study was conducted from June to November 2018 around the educational fish ponds of Hasanuddin University, Bojo Village, Mallusetasi Sub-District, Barru District, Indonesia. This study aimed to identify the mangrove species present, the crustacean and molluscan macrozoobenthos associated with the mangrove ecosystem, and to evaluate the level of stability of the mangrove ecosystem for the development of edu-tourism activities at the study site employing a Macrozoobenthos Ecological Index. Data on mangrove, macrozoobenthos, and other environmental parameters, were collected at five stations with three replicates per station. Mangrove data was collected within 10 m × 10 m plots, while macrozoobenthos were collected with a shovel and sieve net. Seven mangrove species were found: Avicennia marina, Bruguiera gymnorhiza, Ceriops decandra, Rhizophora apiculata, Rhizophora mucronata, Rhizophora stylosa, and Sonneratia alba. The width of the mangrove belt ranged from 28.23 to 57.00 m meaning that it was well below the national green belt standard (50-200 m). The organisms associated with mangroves included crustaceans (three species) and molluscs (seven species) with an abundance of 0.01 - 0.07 ind/m2. The Diversity Index was in the average category (1.49 - 1.92), while the Evenness Index ranged from unstable to under pressure (0.476 to 0.64). The Dominance Index was in the unstable category (0.185 - 0.264). Based on the Macrozoobenthos Ecology Indicator, the mangrove ecosystem in the fish ponds was categorised as stable to average. The land suitability analysis indicated that the mangrove ecosystem in the study site was in the conditionally appropriate category for the development of mangrove edu-tourism activities.

Published: December 2019

Abstract
In Indonesia, flyingfish are abundant and distributed in Makassar Strait, Flores Sea, Banda Sea, Sulawesi Sea, Maluku Sea, Arafura, Northern Sea of Papua, and Halmahera. The aims of this study were to analyse and describe the characteristics of flyingfish habitat, based on oceanographic conditions and eggs catches, and to visualize the variability in spatial and temporal patterns of predicted potential spawning grounds. The research was conducted in Fak-Fak and adjacent seas in the Indonesian Fisheries Area WPP 715, from 130°−134° E and 2°S−5° S. Data were collected during 2018 for selected months: June, July, August and September. Remote sensing data used in this study included chlorophyll-a concentration (Chl-a) OCI-Algorithm, Sea Surface Temperature (SST) 11μ daytime, Absolute Dynamic Topography (ADT), Significant Wave Height and Ocean Surface Current (meridian and zonal components). Fishery data were collected from fishermen’s GPS units, and through participatory mapping. Based on the mapping of fishing locations of flyingfish fishermen, there were four locations where fishing frequency was high. The potential fishing grounds were approximately 5-40 miles from mainland of Fak-Fak. Chlorophyll-a concentration in Fak-Fak waters ranged from 0.201–2.13 mg/m3. The temperature was estimated to be in the range of 27-31°C, with an average temperature of 27.1°C. ADT only changed by 0.01 cm in height each month with a range between 0.88–1.02 cm. Wind was one of the driving forces of geostrophic current. The waves reached a peak in August, with heights ranging from 0.70 to 1.6 metre. Flyingfish were predominantly found in oceanic zones.

Abstract
Large pelagic fish (LPF hereafter) is an important group of fishes targeted by local fishermen in the Indonesian Fisheries Management Area-713 (IFMA-713). This IFMA includes the Makassar Strait, Flores Sea, Bali Sea, and Gulf of Bone. The objective of this study was to identify the preferred oceanographic conditions based on LPF fishing grounds in the study area. The experimental fishing was conducted from April to September 2018 by using local commercial fisheries (pole and line and purse seine). The fishing base of pole and line vessels operating in the Gulf of Bone was at Murante fish landing site, Luwu Regency, South Sulawesi. On the other hand, the fishing base of purse seine vessels operating in the Makassar Strait was at Siddo fish landing site, Barru Regency, also in South Sulawesi. Oceanographic factors such as sea surface temperature (SST), sea surface chlorophyll-a (SSC) concentration, and depth were derived from satellite data. The LPF fishing grounds were analysed and visualize using Geographic Information System (GIS) techniques. Based on the results, LPF distributions tended to be the highest in specific oceanographic conditions, including SST of 30.0 - 31.0 °C and SSC of 0.20 - 0.30 mg.m−3. They were mostly found in nearshore and offshore areas (maximum depth of about 2,000 m). The selected oceanographic factors played an important role in explaining the LPF fishing grounds. This information could be used for spatial prediction of potential LPF fishing zones in relation to the fish distribution and abundance during the Southeast monsoon in the IFMA-713.

Abstract

Channa micropeltes or toman is a native freshwater fish species and not commercially species in Malaysia. The fish become one of the anglers’ attractions to Kenyir Lake, especially for recreational fishing purpose. However, parasitic diseases are one of the most common problems for this fish population. Studies on parasites of C. micropeltes is essential to our knowledge for the maintenance of natural resources. So, the objectives of this study were to identify the cestode and observe the histopathological changes on gastrointestinal tract of infected C. micropeltes. About 15 C. micropeltes were caught by using fishing rod. The fish were pithing, dissected and gastrointestinal tract was removed, then placed on petri dish. The stomach and intestine were fixed in 10% buffered formalin and proceed for preparing histology slides by using standard method for histology. Then, the tissues were stained by using hematoxylin and eosin (H & E) stain. The tissue changes were described. The cestodes were collected, fixed in 70% ethanol, stained with aceto-carmine and prepared the permanent slide. The cestodes morphology were observed under microscope for identification. In this study, only Senga rostellarae was identified. The histopathological changes showed the intestine with severe villus damage with destruction of villi epithelium and necrosis. Some areas with cross section of cestode showed increase of goblet cells and generated necrosis. Based on this study, S. rostellarae was a dominant species, and its activities caused severe damage to the fish intestine. The conditions can cause death to the fish due to hemorrhage and malabsorption of nutrient.

The Demise of the World of the Gutnajers: The Warsaw Art Market in World War II
Authors: Cieślińska-Lobkowicz Nawojka 
Published: December 2019

Abstract
A substantial number of Jewish art and antiques dealers operated in pre-World War II Warsaw. Particularly respected were the salons of the brothers Bernard and Abe Gutnajer. Virtually everyone in their milieu perished in the Warsaw ghetto or Treblinka. Taking their place were new “Aryan” dealers and a clientele of “new” money. The Warsaw art market under the German occupation experienced a particular growth between the start of the Jewish ghetto’s liquidation in mid-1942 and the outbreak of the Warsaw Uprising in August 1944, as “abandoned” property flooded the market. After decades of subsequent turbulent history, researchers can hardly hope to document the provenance of more than a fraction of tens of thousands of surviving works of art and valuable antiques.
Marginal measures and causal effects using the relative survival framework
Authors: Syriopoulou Elisavet , Rutherford Mark J , Lambert Paul C 
Published: December 2019

Abstract

Background
In population-based cancer survival studies, the event of interest is usually death due to cancer. However, other competing events may be present. Relative survival is a commonly used measure in cancer studies that circumvents problems caused by the inaccuracy of the cause of death information. A summary of the prognosis of the cancer population and potential differences between subgroups can be obtained using marginal estimates of relative survival.

Methods
We utilize regression standardization to obtain marginal estimates of interest in a relative survival framework. Such measures include the standardized relative survival, standardized all-cause survival and standardized crude probabilities of death. Contrasts of these can be formed to explore differences between exposure groups and under certain assumptions are interpreted as causal effects. The difference in standardized all-cause survival can also provide an estimate for the impact of eliminating cancer-related differences between exposure groups. The potential avoidable deaths after such hypothetical scenarios can also be estimated. To illustrate the methods we use the example of survival differences across socio-economic groups for colon cancer.

Results
Using relative survival, a range of marginal measures and contrasts were estimated. For these measures we either focused on cancer-related differences only or chose to incorporate both cancer and other cause differences. The impact of eliminating differences between groups was also estimated. Another useful way for quantifying that impact is the avoidable deaths under hypothetical scenarios.

Conclusions
Marginal estimates within the relative survival framework provide useful summary measures and can be applied to better understand differences across exposure groups.

Published: December 2019

Abstract
Insects are potential ingredients for animal feed and human food. Their suitability may be influenced by species and nutritional value. This study was aimed at determining the nutritional profile of four insects: Dipterans; black soldier fly (Hermetia illucens Linnaeus) family stratiomyidae and blue calliphora flies (Calliphora vomitoria Linnaeus) family Calliphoridae; and orthopterans; crickets (Acheta domesticus Linnaeus) family Gryllidae and grasshoppers (Ruspolia nitidula Linnaeus) family Tettigoniidae to establish their potential as alternative protein sources for animals (fish and poultry) and humans. Gross energy, crude protein, crude fat, crude fiber, carbohydrates, and total ash were in the ranges of 2028.11–2551.61 kJ/100 g, 44.31–64.90, 0.61–46.29, 5.075–16.61, 3.43–12.27, and 3.23–8.74 g/100 g, respectively. Hermetia illucens had the highest energy and ash content; C. vomitoria were highest in protein and fiber content, R. nitidula were highest in fat, whereas A. domesticus had the highest carbohydrate content. All insects had essential amino acids required for poultry, fish, and human nutrition. The arginine to lysine ratios of H. illucens, C. vomitoria, A. domesticus, and R. nitidula were 1.45, 1.06, 1.06, and 1.45, respectively. The fatty acids comprised of polyunsaturated fatty acids (PUFAs) and saturated fatty acids (SFAs). Palmitic acid (23.6–38.8 g/100 g of total fat) was the most abundant SFA, exception R. nitidula with 14 g/100 g stearic acid. Linoleic acid (190–1,723 mg/100 g) and linolenic acid (650–1,903 mg/100 g) were the most abundant PUFAs. Only C. vomitoria had docosahexaenoic acid. The study indicates that the insects studied are rich in crude protein and other nutrients and can potentially be used for human and animal (fish and poultry) feeding.
