AstroSat Observations of GRO J2058+42 during the 2019 Outburst
Authors: Mukerjee Kallol , Antia H. M. , Katoch Tilak
Published: July 2020

We present results from AstroSat observations of the recent outburst of GRO J2058+42, an X-ray pulsar in a Be-binary system. The source was observed by the LAXPC and SXT instruments on AstroSat on 2019 April 10 during the declining phase of its latest giant outburst. Light curves showed a strong pulsation of the pulsar with a period of 194.2201 ± 0.0016 s and a spin-up rate of (1.65 ± 0.06) × 10−11 Hz s−1. Intermittent flaring was detected in light curves between the 3 and 80 keV energy bands, with an increase in intensity of up to 1.8 times its average intensity. Pulse profiles obtained between the 3 and 80 keV energy bands of the pulsar showed strong dependence on energy. During AstroSat observations, a broad peak was consistently observed in the power density spectrum of the source with a peak oscillation frequency of 0.090 Hz along with its higher harmonics, which may be due to quasi-periodic oscillations, a commonly observed phenomenon in transient X-ray pulsars during their outburst. AstroSat observations also detected cyclotron absorption features in its spectrum corresponding to (9.7–14.4) keV, (19.3–23.8) keV, and (37.8–43.1) keV. The pulse-phase-resolved spectroscopy of the source showed a phase-dependent variation in its energy and the relative strength of these features. The spectrum was well fitted with an absorbed blackbody, Fermi–Dirac cutoff model and alternatively with an absorbed CompTT model. Both of these models were combined with an Fe line and three Gaussian absorption lines to account for the observed cyclotron resonance scattering features in the spectrum.
On the Dependency between the Peak Velocity of High-speed Solar Wind Streams near Earth and the Area of Their Solar Source Coronal Holes

Published: July 2020

The relationship between the peak velocities of high-speed solar wind streams near Earth and the areas of their solar source regions, i.e., coronal holes, has been known since the 1970s, but it is still physically not well understood. We perform 3D magnetohydrodynamic (MHD) simulations using the European Heliospheric Forecasting Information Asset (EUHFORIA) code to show that this empirical relationship forms during the propagation phase of high-speed streams from the Sun to Earth. For this purpose, we neglect the acceleration phase of high-speed streams, and project the areas of coronal holes to a sphere at 0.1 au. We then vary only the areas and latitudes of the coronal holes. The velocity, temperature, and density in the cross section of the corresponding high-speed streams at 0.1 au are set to constant, homogeneous values. Finally, we propagate the associated high-speed streams through the inner heliosphere using the EUHFORIA code. The simulated high-speed stream peak velocities at Earth reveal a linear dependence on the area of their source coronal holes. The slopes of the relationship decrease with increasing latitudes of the coronal holes, and the peak velocities saturate at a value of about 730 km s−1, similar to the observations. These findings imply that the empirical relationship between the coronal hole areas and high-speed stream peak velocities does not describe the acceleration phase of high-speed streams, but is a result of the high-speed stream propagation from the Sun to Earth.
Framing of Task Forces as an Outcome of Transformation of Force Using Scenarios into Capability Requirements
Authors: Petráš Zdeněk
Published: July 2020

The aim of the article is to broaden scientific discussion held within the defence and security community on methodological approach to scenario development process. The author brings an innovative look at the concept of modular task force development, which is considered, in his conception, as a result of interconnection between capability requirements arisen from scenario analysis process, and respective type of force units being a part of the current military structure. The author´s approach to task force generation process, illustrated by a case study, is a synthesis of best practices and findings derived from national as well as EU and NATO planning processes. The proposed concept of the task force generation might be perceived as an effective tool for supporting strategic decision-making process.
A new pioneer association of detrital substrata of the hilly and low-mountain belts in Central Apennines (Italy)

Published: July 2020

Plant communities dominated by Petrosedum ser. Rupestria in Italy have always been referred to the Sedo albi-Scleranthetea biennis Br.-Bl. 1955 class. This group of species was also often found more or less abundant in the garrigue and pasture vegetation. Some unusual plant communities dominated by Petrosedum rupestre (L.) P.V.Heath with a conspicuous presence of typical species of scree vegetation were found and sampled in the Abruzzo region, on more or less mobile debris. In order to classify such communities, syntaxonomic, structural, chorological and ecological analyses have been performed. All the Petrosedum ser. Rupestria dominated communities reported in Italy have been compared with the sampled vegetation. A new perennial pioneer association, linked to more or less mobile detrital substrata of the hilly and lower-mountane belts of the calcareous Central Apennines has been here described with the name Linario purpureae-Petrosedetum rupestris. Based on the syntaxonomic analysis, this association has been included in the Linarion purpureae alliance (Scrophulario bicoloris-Helichrysetalia italici order). The Linario-Petrosedetum has been divided into two subassociations: a typical one named petrosedetosum rupestris and a thermophilous one of the lower altitudes named teucrietosum flavi. The study revealed the originality of such communities and their appropriate classification in the Thlaspietea rotundifolii class. This is the first record in Italy of a Petrosedum ser. Rupestria-rich community framed in the scree vegetation class.
Self-isolation at the dacha: Can’t? Can? Have to?
Authors: Nikolaeva Uliana G. , Rusanov Alexander V.
Published: July 2020

Measures taken by most countries to limit the coronavirus infection spread include self-isolation. An option of voluntary restriction of personal contacts for citizens is to move to the country (second or third) houses, which have a particular name in Russia – “dacha”. The demand for country estates as places of self-isolation can be assessed as the emergence of a new sanitary-epidemic function in second homes.

Institutional management of such movements in connection with the coronavirus pandemic varies by country, ranging from prohibition (Norway) to encouragement (Belarus), and quantitative indicators (mass character or singleness) fluctuate according to lifestyle, national traditions, characteristics of settlement, urban housing policy, public health opportunities and many other factors.

For Russians, the migration of residents of megalopolises from the city to country houses was a reaction to the pandemic, a characteristic social-group strategy of health-preserving behaviour. Several million Muscovites, Petersburgers, as well as residents of other megacities of Russia moved outside the cities immediately after the outbreak of the pandemic. “Half-townspeople” – internal migrant workers and “seasonal workers” (workers living in villages or small towns but working in metropolises in watch mode) also moved to rural areas.

The mass nature of centrifugal spatial-migratory deurbanization model of behaviour of Russians during the pandemic is determined by the specifics of the spatial distribution of the population in Russia, historical features of urbanization and deurbanization processes, in particular, the widespread distribution of second (and third) country houses (dachas) among the citizens. Russia leads both in relative and absolute number of dacha dwellers among the European countries. The number of country houses in Russia is estimated by specialists at 17–20 million, and the number of dacha dwellers at 50–60 million; at least half of the citizens have second (and often third) country houses.

Massive movements of citizens into out-of-town spaces had both positive and negative consequences. A significant share of citizens reduced risks of infection and were able to avoid “imprisonment” within the apartment with accompanying socio-psychological overload and physical inactivity. However, mass movements also contributed to the rapid spread of coronavirus beyond the original foci.

The article considers the approaches of European countries to countryside self-isolation, describes chronicles of restriction on movement of citizens in Russian regions and waves of summer migration during the pandemic, suggests an assessment of dacha migration from the capital, and discusses its short-term socio-economic consequences.
Egg parasitoids of Arboridia apicalis (Nawa, 1913) (Hemiptera, Cicadellidae), a leafhopper pest of grapevines in Japan, with description of a new species of Anagrus Haliday, 1833 (Hymenoptera, Mymaridae)

Published: July 2020

Several species of egg parasitoids (Hymenoptera: Mymaridae and Trichogrammatidae) of the leafhopper pest of grapevines in Japan, Arboridia (Arboridia) apicalis (Nawa) (Hemiptera, Cicadellidae), were reared and identified for the first time. Using a combination of genetic and morphological evidence, Anagrus (Anagrus) arboridiae Triapitsyn & Adachi-Hagimori, sp. nov. (Mymaridae) is described and illustrated from Honshu Island (Shimane Prefecture) and Kyushu Island (Miyazaki Prefecture). It is shown to be different from Anagrus (Anagrus) japonicus Sahad and A. flaviapex Chiappini & Lin, to which it is most similar; the latter species was originally described from China and is newly recorded here from Okinawa Island, Japan. Mitochondrial and nuclear ribosomal DNA sequence data provide clear evidence for the separation of A. arboridiae from A. flaviapex, A. japonicus, and some other members of the Anagrus (Anagrus) atomus (L.) species group. Two other species of Anagrus Haliday, A. (Anagrus) avalae Soyka and A. atomus, are also identified in Japan from eggs of the leafhoppers Edwardsiana ishidae (Matsumura) and Eurhadina ? betularia Anufriev, respectively. An updated key to females of the Japanese species of Anagrus is given. Oligosita pallida Kryger (a new record for Japan), Oligosita sp., and an Aphelinoidea (Aphelinoidea) sp. (Trichogrammatidae) were the other, although much less abundant, apparent egg parasitoids of A. apicalis in Shimane Prefecture, mainly in non-organic vineyards.

Short‐term investments and indices of risk
Authors: Heller Yuval , Schreiber Amnon
Published: July 2020

We study various decision problems regarding short‐term investments in risky assets whose returns evolve continuously in time. We show that in each problem, all risk‐averse decision makers have the same (problem‐dependent) ranking over short‐term risky assets. Moreover, in each problem, the ranking is represented by the same risk index as in the case of constant absolute risk aversion utility agents and normally distributed risky assets.
What corporate social responsibility in sub-Saharan Africa?
Authors: Boidin Bruno , Ballet Jérôme
Published: July 2020

This article analyses the form of corporate social responsibility (CSR) in sub-Saharan Africa, more particularly in the mining sector in Senegal. To that end, account has to be taken of the major institutional characteristics of low-income countries. One of the major characteristics is the existence of weak states. We show a quadruple characterization: a weak commitment of the state; a still high degree of corruption; a poor decentralisation process; a weak social state that makes companies uncomfortable with their CSR practices.
Mathematics shows that the Lorentz transformations are not self-consistent
Authors: Slowak Jan
Published: July 2020

Einstein's theory of special relativity is a generally accepted theory that analyses relationships between two inertial reference frames moving at a constant speed against each other. In this work, we analyze the derivation of the Lorentz transformations only from the point of view
of mathematics. This analysis comes to contradiction with the original conditions for the derivation of the Lorentz transformations. This leads to the conclusion that the Lorentz transformations are not self-consistent.
Special relativity and the Lorentz sphere
Authors: Crothers Stephen J.
Published: July 2020

The special theory of relativity demands, by Einstein's two postulates (i) the principle of relativity and (ii) the constancy of the speed of light in vacuum, that a spherical wave of light in one inertial system transforms, via the Lorentz transformation, into a spherical wave of light
(the Lorentz sphere) in another inertial system when the systems are in constant relative rectilinear motion. However, the Lorentz transformation in fact transforms a spherical wave of light into a translated ellipsoidal wave of light even though the speed of light in vacuum is invariant.
The special theory of relativity is logically inconsistent and therefore invalid.
Newtonian quantum gravity
Authors: Ziefle Reiner Georg
Published: July 2020

Newtonian Quantum Gravity (NQG) unifies quantum physics with Newton's theory of gravity and calculates the so-called “general relativistic” phenomena more precisely and in a much simpler way than General Relativity, whose complicated theoretical construct is no longer needed.
Newton's theory of gravity is less accurate than Albert Einstein's theory of general relativity. Famous examples are the precise predictions of General Relativity at binary pulsars. This is the reason why relativistic physicists claim that there can be no doubt that Einstein's theory of relativity
correctly describes our physical reality. With the example of the famous “Hulse-Taylor binary” (also known as PSR 1913 + 16 or PSR B1913 + 16), the author proves that the so-called “general relativistic phenomena” observed at this binary
solar system can be calculated without having any knowledge on relativistic physics. According to philosophical and epistemological criteria, this should not be possible, if Einstein's theory of relativity indeed described our physical reality. Einstein obviously merely developed an alternative
method to calculate these phenomena without quantum physics. The reason was that in those days quantum physics was not yet generally taken into account. It is not the first time that a lack of knowledge of the underlying physical phenomena has to be compensated by complicated mathematics.
Einstein's theory of general relativity indirectly already includes additional quantum physical effects of gravitation. This is the reason why it cannot be possible to unite Einstein's theory of general relativity with quantum physics, unless one uses “mathematical tricks” that
make the additional quantum physical effects disappear again in the end.

Published: July 2020

The development of energy storage devices encourages the sustainability of research on basic materials of supercapacitor technology. SrTiO3 is one of metal oxide called as titanate alkali metal ATiO3 (A = Ba, Sr, Ca). This material shows an excellent dielectric constant, thus expected to be potential as raw material of supercapacitor. In this work, boron was used as a dopant on the SrTiO3 system to modify its local structure and enhance the electrical properties. Synthesis SrTi1-xBxO3 was carried out using a solid-state reaction method followed by the sintering process in various molar ratio. The microstructure of SrTi1-xBxO3 compound was identified by X-ray Diffraction with Cu-Kα. XRD pattern identified the presence of SrTi1-xBxO3 phase with a slight change in the lattice parameters. I-V measurement confirmed that the electrical conductivity increased gradually up to 16.04 Ω-1cm-1. For investigating their application for electrode materials, CV was employed and it presents that the specific capacitance and energy density of x = 0.08 were 5.488 Fg-1 and 0.110 Jg-1.

Published: July 2020

Dye-sensitized solar cells (DSSCs) is a part of the third-generation family which have been developed under substantial research for almost three decades due to their low-cost fabrication, low toxicity, and can be manufactured on the flexible substrate. However, the challenge for the improvement of current DSSC is still opened, especially in the scope of efficiency, stability, and platinum (Pt)-free counter electrode. In this work, the incorporation of solution-processed rGO as a replacement for the Pt counter electrode DSSC is demonstrated. The rGO solutions with three different concentrations (1, 3, and 5 wt%) are utilized. The highest power conversion efficiency (PCE) of about 0.1 % is displayed by 5 wt% rGO solution based devices. The results reported in this work exhibited the high potential of solution-processed rGO as an efficient alternative material in the counter electrode of DSSC.

Published: July 2020

Electric bicycles are one of the two-wheeled transportation that has been widely used. The structure of the bicycle is generally composed of several components, one of which is the frame. The frame serves to support the load on the bicycle. At present, many changes in design, geometry and bicycle-forming materials have been carried out. In general, bicycle frames are made of metal and alloy because they have good strength to support the load of the driver. Lately, the use of composites has begun to develop as a bicycle frame material, because the frame of the bicycle has become lighter but still has the strength to support the load. This paper presents a study of the structure of electric bicycles using composite material based on epoxy matrices with rami fiber reinforcement. This study used an experimental and simulation method by designing composite laminates with A(90o/90o/90o), B(90o/45o/90o), and C(45o/45o/45o) fiber webbing layout and then carried out free compressive strength (UCS), optical microscopy and simulation using ANSYS 19.0 software. The results obtained are composite laminate design with a woven fiber layout (45o/45o/45o) having the highest strength value with a compressive stress value σ=58.64 MPa in the axial compressive plane, and σ=1.539 MPa in the tangential compressive plane. Likewise, the simulation results also obtained the highest strength in the webbing design (45o/45o/45o) which is equal σs=58.72 MPa in the axial compressive plane and σs=1.531 MPa in the tangential compressive plane.

Published: July 2020

Micro-fibrillated celluloses (MFCs) are made from oil palm empty fruit bunches (EFB). EFB is processed through several stages of the process, including washing, alkalization, and bleaching to remove impurities, lignin, and hemicellulose. Each treatment stage was characterized by differential scanning calorimeter (DSC) and thermogravimetric (TGA) analysis. Morphological analysis was characterized using Scanning Electron Microscope (SEM). The process results show that MFC has an average length and thickness of 450 and 80 microns for coarse fibers respectively, averaging 50 and 5 microns for fine fibers, respectively. Fibrillation fibers appear on the surface of fibers which are treated using alkalization and bleaching processes. The TGA results showed a decrease in weight occurred at a temperature of 40 to 109 °C for the first stage of the heating process and at a temperature of 247 to 382 °C for the second stage. The decrease in fiber weight is caused by evaporation of water content and degradation of cellulose compounds at each stage. The glass transition temperature of MFC was obtained at 236 °C. The thermal stability of cellulose from fibers treated using alkalization and bleaching processes proved the formation of cellulose crystals. Removal of lignin and hemicellulose is shown by the absorption of O-H and C-C bonds in FTIR spectroscopy. From these results, it is stated that micro-fibrillation cellulose is formed well through a series of processes given.

To obtain the high specific capacity anode for Lithium-ion battery with stable performance is conducted by synthesizing a composite anode of ZnO-nanorods (ZnO-NR) and as a matrix is the activated carbon (AC). In this study, ZnO-NR synthesized a process that uses basic materials hexamethylenetetramine (HMTA) and zinc oxide. Activated carbon has been activated because it has high porosity and good electrical conductivity properties. Variable used is the percentage of ZnO-NR, which is 30wt%, 40wt%, and 50wt%. Characterization of the samples was examined using X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM), and Brunauer–Emmett–Teller (BET). The battery performance of the samples was obtained by Electrochemical Impedance Spectroscopy (EIS), Cyclic Voltammetry (CV), and Charge-Discharge (CD) testing after being assembled into coin cell batteries. This study discusses the effect of adding activated carbon to ZnO NR composites. The results showed that the ZnO-NR30/AC has the highest specific capacity of 270.9 mAh g-1. According to Brunner-Emmet-Teller (BET) test, the largest surface area was 631.685 m2 g-1. Electrochemical performance is the best obtained by ZnO-NR30/AC.

Here, we present a numerical approach to analyze the integrity of a vessel that was subject to a weld repair. A Post-Weld Heat Treatment (PWHT) process was implemented to a vessel undergone weld repair due to leakage. Due to the thick wall of the welded bottom head, this welding process must be followed by the PWHT to relieve the residual stress, as well as to improve the material properties. PWHT process was performed by heating the welded area to reach 675 °C temperature. A numerical approach using finite element analysis (FEA) method was performed to analyze the integrity of the vessel. Based on the analysis, the structure is still stable within the applied load. PWHT process does not lead to buckling on the main structure and the load is still lower than the load required for the occurrence of buckling. A sensitivity analysis was also performed with reduced temperatures to 630 °C or reduction of PWHT area width. These changes were found to have negligible effects in reducing the stress and strains in the vessel. After PWHT is completed, the structure is still considered to be safe to be operated, as indicated by its strain that is still below the allowable strain and only relatively small deflection was occurred.

Osteosarcoma, as the most frequent bone tumor cases, can be found in the pelvis bone. Within the pelvis, the ilium is the most common location for osteosarcoma, followed by the acetabulum and then the ischium. Surgery of pelvis is difficult and the reconstruction is complicated mainly due to the geometry complexity and also the weight support function of the pelvis. Endoprosthesis of the ilium is therefore designed to increase the quality of life of the patient. In this study, the iliac implant is designed based on the natural geometry of the ilium, and the size is modified to fit the morphometry of the Eastern Asian. A finite element method (FEM) is proposed as a basic study in material selection. Titanium and its alloy (Ti-6Al-4V) are studied as the potential candidate for the proposed implant while the finite analysis of the bone was also included. As a preliminary study, in this FEM, only the static load is given, each material is assumed to be isotropic and the contacts were considered bonded. FEM in this study is expected to give a better understanding of the stress distribution, and to optimize the selection of materials.

The present study was carried out to assess the effects of bio-organic and inorganic fertilizers on plant nutrients, essential oil composition and antioxidant capacity of Satureja macrantha L. The experiment included nine treatments viz., NPK (50:25:25 kg ha−1), Vermicompost (VC) (5 t ha–1), NPK +VC, Thiobacillus (T), T+VC, T+sulfur (S) (250 kg ha−1), T+S 500 kg ha−1, Glomus mosseae, and control (untreated plants). The results showed the highest Essential Oil (EO) content and yield were respectively observed in plants treated with the combination of VC and NPK. Total Phenol Content (TPC) in first-year plants treated with VC and second-year plants under NPK+VC were higher than other experimental plants. Total Flavonoid Content (TFC) in second-year plants under the combination of NPK was greater than other plants. N content in first year plants treated with NPK fertilizer / combination of NPK and VC was higher compared to other experimental plants. The highest P content was observed in the NPK application in first year. Gas Chromatography—Mass Spectrometry (GC/MS) analyses revealed that the main constitutes of S. macrantha EO were p- Cymene (16.30-34.64%), γ-terpinene (15.46-33.6%), and Thymol (14.82-43.09%), which had different responses to sampling time and fertilizer treatments.
