Registration of gravitational waves emitted by periodic astrophysical sources: prospects for GW-astronomy and stellar navigation
Authors: Siparov S V 
Published: June 2020

Abstract
All the efforts to directly detect the gravitational waves (GW), including the recent successes of the LIGO and VIRGO teams, are focused on registering the catastrophic events in deep space. The two main features of this activity are the unpredictability of these events and the extreme sensitivity of the necessary equipment. The principally new method of the GW detection is based on the effect of optic-metrical parametric resonance (OMPR) and does not require catastrophic events and supersensitive equipment. The corresponding theory shows that the periodic GW, emitted by a short-period binary star, acts on a distant astrophysical maser and produces a specific signal that can be registered by a regular radio telescope. The main feature of such signal is the periodic change of the intensity of the only one detail in a maser’s spectrum. The observations of 49 such masers were performed with the RT-22 radio telescope at Pushchino Observatory of RAS. The program of signal processing included the identification of periodic components in a spectrum, the elimination of artifacts associated with the observation procedure, and the determination of the frequencies of periodic components. After that the corresponding binary stellar systems were identified. Thus, close binaries become a kind of GW-beacons in the Milky Way. This gives rise to the GW-astronomy, provides obvious applications for stellar navigation and gives a clue to the study of the geometric structure of our galaxy.
A Space-Frame Periodic Table Representation System Testing Relativity in Nucleosynthesis of the Elements
Authors: Trell E 
Published: June 2020

Abstract
The geometric Lie algebra SU(3) isotropic vector matrix realization of the periodic table reported at PIRT 2017 has now been broken up to a disjoint-set modular R3×SO(3) building kit, exactly sufficing to stage the Big Bang and ensuing nucleosynthesis events: First the ultrashort radiation/plasma inflation of the Big Bang phase transition moment with release of photons, neutrinos and module precursors, which in next seconds recombine to the Protium proton/electron compound and its neutron conversion to continue separately or in fusion of the two get on to Deuterium and from there to Tritium, Helium in isotope and α form, and traces of Lithium and possibly Beryllium. That is, literally the whole primordial start-gas delivered within a few minutes to billion-year wait for sufficiently energetic perturbations with itself for astrophysical/cosmogenic/experimental nucleosynthesis of the full periodic table and likewise replicable by systematic space-filling assembly/disassembly of the here disclosed neutrino and photon lattice vector, β particle, α wave-packet and neutron building bricks, providing clues also on isotope/neutron excess, shell/subshell, spectroscopy, and chemical bond structural make-up and disposition. Furthermore, the absolute trigonometric sharpness of the nucleosynthesis phase transition burst and expansion is reciprocal to the absolute speed of light and hence a specific test and verification of the relativity theory.

Abstract
Here, we discuss the cosmic evolution in the presence of collisional matter (CM) with and without radiations within the framework of modified teleparallel theories. We opt f(T, B) theory (where T stands for torsion scalar and B represents the boundary term associated to the divergence of torsion 2∇

= B), which makes a good connection between f(R) (R for Ricci Scalar) and f(T) (T for torsion) theory under reasonable conditions. The power law and logarithmic f(T, B) models are selected to discuss the behavior of deceleration parameter q(z), Hubble parameter H(z), Equation of state (EoS) for dark energy (DE), and effective EoS. We found the great oscillations of EoS for DE across the phantom divide line. Effective EoS also crossed the phantom divide line without any oscillations. The graphs for H(z), q(z), effective EoS are alike for NCM with radiations, CM without radiaitons and CM with radiations.
Photons as solitons
Authors: Chernitskii A A 
Published: June 2020

Abstract
The field model of space-time film is considered. New class of exact solutions is discussed. These solutions are solitons moving with the speed of light or light-like solitons. Subclass of these solutions with approximate helical symmetry or having twist is considered. Determinate conformity of twisted light-like solitons and photons is shown. In particular, the obtained expression of the soliton energy coincides with the appropriate expression for photon in high-frequency approximation. Planck formula is obtained (in some approximation) for the equilibrium energy spectral density of the ideal gaze of the twisted solitons. An experimental check of the modified formula for the energy of photon (in low-frequency region) as the twisted light-like soliton is proposed.

Authors: Fil’chenkov M L , Laptev Yu P 
Published: June 2020

Abstract
The minihole coalescences and quadrupole transitions of hydrogen atoms and hydrogen-like graviatoms are considered to be sources of the gravitational background radiation. The total energies of the gravitational radiation of these microsystems have been calculated. This gravitational background proves to be comparable with the observed gravitational radiation from the coalescence of stellar mass black holes.
The exact solutions in verified cosmological models based on generalized scalar-tensor gravity
Authors: Fomin I V , Chervon S V 
Published: June 2020

Abstract
We consider the cosmological models built on the basis of scalar-tensor gravity, in which the non-minimal coupling of a scalar field and the Ricci scalar leads to the evolution of the field, the deviation of its potential from the flat shape and the difference in the dynamics of the early universe from pure exponential expansion. It is shown that such models are in a good agreement with modern observational data. As an example of the application of the proposed approach, the exact solutions for the different models of cosmological inflation were obtained.
Dynamical symmetry breaking in Abelian geometrodynamics
Authors: Garat A 
Published: June 2020

Abstract
A new tetrad is introduced within the framework of geometrodynamics for non-null electromagnetic fields. This tetrad diagonalizes the Einstein-Maxwell stress-energy tensor, any stress-energy tensor in a local and covariant way, and allows for maximum simplification of the expression of the electromagnetic field, in any curved four-dimensional Lorentzian spacetime, allowing for the identification of its degrees of freedom in two local scalars. New isomorphisms are proved. A new internal-spacetime mapping is established using these new tetrads. It is possible to map the local group of electromagnetic gauge transformations into the transformation groups of tetrad vectors on two local orthogonal planes. The planes that diagonalize the stress-energy tensor. We will discuss through a first order perturbative formulation the local loss of symmetry when a source of electromagnetic and gravitational field interacts with an agent that perturbs the original geometry associated to the source. The loss of symmetry will be manifested by the tilting of these planes under the influence of an external agent. In this strict sense the original local symmetry will be lost, however a new symmetry will arise. The purpose of this report is to show that the geometrical manifestation of local gauge symmetries is dynamic.
Spacetime and inner space of spinors in the theory of superalgebraic spinors
Authors: Monakhov V V 
Published: June 2020

Abstract
We constructed gamma operators which are superalgebraic analogs of the Dirac gamma matrices as well as two additional gamma operators which have no analogs in the Dirac theory. We found a new mechanism of the left-right symmetry breaking which is absent in the usual theory of Dirac spinors. We constructed Lorentz invariant gamma operators from operators of creation and annihilation of spinors. These gamma operators are also analogs of the Dirac gamma matrices, however they are not related to Lorentz transformations but generate vector fields as affine spinor connections. We have shown that the theory is equivalent to an extended version of the Pati-Salam theory.

Abstract
LCFT is special conformal field theory with logarithmic terms in operator product expansion OPE. It is well-known that it is possible to construct operators with logarithmical terms in OPE at Liouville model. Here we discuss this topic for some generalization of Liouville model, such as Sine-Liouville model.
Resolving cosmological singularity problem in logarithmic superfluid theory of physical vacuum
Authors: Zloshchastiev K G 
Published: June 2020

Abstract
A paradigm of the physical vacuum as a non-trivial quantum object, such as superfluid, opens an entirely new prospective upon origins and interpretations of Lorentz symmetry and spacetime, black holes, cosmological evolution and singularities. Using the logarithmic superfluid model, one can formulate a post-relativistic theory of superfluid vacuum, which is not only essentially quantum but also successfully recovers special and general relativity in the “phononic” (low-momenta) limit. Thus, it represents spacetime as an induced observer-dependent phenomenon. We focus on the cosmological aspects of the logarithmic superfluid vacuum theory and show how can the related singularity problem be resolved in this approach.

Authors: Suprapto D , Purwanti S , Agustina L 
Published: June 2020

Abstract
Animal husbandry development has an important role in the effort to meet the needs of animal protein in the community. Digestion of feed substances is one of the benchmarks in determining the quality of feed ingredients, in addition to their chemical composition. To study digestibility and fermentation in the digestive tract, a very successful and widely used method is the In-vitro technique. Turmeric (Curcuma domestica) is a plant that pledged as phytobiotic feed additive group at poultry. Indigofera zollingeriana is a legume plant that has the potential as a feed ingredient for protein sources with high protein content along with relatively low fibre content and a high digestibility rate. This plant is very good as a source of forage feed in poultry. The design used in this study was a completely randomized design (CRD) with 4 treatments and 5 replications. The composition of the research treatment was as follows: without TPDI and turmeric flour (P0), substituting 6% soybean meal protein with 10% TPDI and 2.5% turmeric flour (P1), substituting 9% soybean meal protein with 15% TPDI and 2, 5% turmeric flour (P2), 12% substitution of soybean meal protein with 20% TPDI and 2.5% turmeric flour (P3). Changes observed were dry matter digestibility and protein digestibility. The results showed that the substitution of soybean meal protein with Indigofera zollingeriana shoot flour at different levels and the addition of turmeric significantly affected dry matter digestibility and protein digestibility (p<0.05). The average digestibility of dry matter P1 gave a significantly lower difference with P2 and P3 (p<0.05) and in P3 protein digestibility the difference was significantly lower with P0 and P1 (p<0.05). This study concludes that the administration of Indigofera zollingeriana at the level of 10% and 2.5% turmeric was able to improve dry matter digestibility by 84.96% and protein digestibility by 35.99%.

Abstract
The use of such agricultural by-products as rice straw is important in fulfilling the needs of feed for ruminants, especially during the dry season. However, the main problem of using rice straw a feedstuff is low digestibility due to the existence of the links between lignin and cellulose or hemicellulose. This study was designed to evaluate the effects of the application of biostarter (BS) developed from rumen bacterial of buffalo on the of the changes of the chemical composition of the rice straw under a different duration of fermentation time. The experiment was carried out in a factorial arrangement according to a completely randomized design. The first factor was different levels of BS application, i.e. rice straw without BS (a1), rice straw + 5% BS (a2), rice straw +10% BS (a3), and rice straw + 15% BS (a4). The second factor was the duration of the fermentation time, i.e., two weeks (b1) and four weeks (b2). Each treatment combination was repeated three times, giving the total number of the experimental unit was 24. The results of the study indicated that increased levels of BS had a significant (P<0.05) effect on the concentration of crude protein, crude fiber, ash, and nitrogen-free extract (NFE) of the rice straw but no effects (P>0.05) on lipid content. The length of the fermentation period only affected (P<0.05) the crude fiber and crude protein content but no effects (P>0.05) on NFE, lipid, and ash. There was no interaction between levels of BS and the duration of the fermentation time on the chemical components of the rice straw. In conclusion, the use of BS was successfully changing the chemical composition of rice straw.

Authors: Tahir H A , Mujnisa A , Jamilah  
Published: June 2020

Abstract
Broiler chicken is a type of chicken that has a fast growth rate and requires large amounts of nutrients absorbed from feed. Absorption of nutrients in the feed requires the function of a good digestive tract to optimize the digestive process. The digestive process also requires optimal time in absorption of feed nutrients called the digesta rate. The purpose of this study was to determine the right level of addition aloe vera powder to the length of digestive tract and the rate of broiler digestion. This study used a completely randomized design with 4 treatments and 4 replications, namely P : feed without aloe vera powder (control), P : feed + 0.075% aloe vera powder, P : feed + 0,1% aloe vera powder and P : feed + 0,125% aloe vera powder. The treatment had a significant effect on the jejenum length and digestion rate, but it had no significant effect on the duodenum length and the ileum lenght. The jejunum length was significantly different in treatment P (85.50 cm) and P (83.75 cm) compared to treatment P (73.25 cm). Digestion rate of broilers was significantly different from the P treatment compared to the control treatment. The results of the study showed that the addition of aloe vera powder with the best level was 0.125% (P ) which optimizes the jejunum length and the rate of digesta broiler.

Published: June 2020

Abstract
This study aims to determine the effect of Liquid Smoke Addition in Coconut Water Multinutrient Block (CWMB) to quail on the nutrient consumption such as crude protein, crude fiber, crude fat and nitrogen-free extract. The treatments consisted of T0: control AkMB ration without liquid smoke addition; T1: CWMB ration with 0.25% liquid smoke, T2: CWMB ration with 0.50% liquid smoke, T3: CWMB ration with 0.75% liquid smoke. The data obtained were analyzed with Completely Randomized Design (CRD) with 4 treatments and 4 replications. The results showed that the effect of liquid smoke in the CWMB ration significantly affected (P <0.05) the consumption of crude protein, crude fiber, crude fat and nitrogen-free extract. Based on these results, it can be concluded that the addition of liquid smoke in the CWMB ration at different levels affected the quail consumption and nitrogen-free extract. The best results obtained in the 0.75% liquid smoke supplementation (T3) that can increase consumption of crude protein and crude fiber in quails. However, the addition of liquid smoke at 0.25-0.75% to CWMB ration can increase quail’s crude fat consumption and nitrogen-free extract.

Abstract
The effect of the different clipping time on the yield and quality of Dwarf Napiergrass under manure application were investigated in this experiment. In relation to plant growth and quality, the needs of grassland for fertilizer nutrients are influenced by the intensity of management, by whether the forage crop is harvested by clipping and the botanical composition of the forage crop. Manure contains essential plant nutrients and to use as a soil amendment for crop production is a practical method, so as to solve the disposal problem of livestock. Dwarf napiergrass as a perennial summer crop under the blocked design with 2 plants m−2 were applied to 3 levels of manure and 4 clipping times. The manure revealed so effective fertilizer to increase dry matter yield, and forage quality, especially in crude protein content and in vitro dry matter digestibility (IVDMD) at the same clipping time with the increase in manure application level.
