Abstract
UV light and air pollution are sources of free radicals that can trigger skin problems. Skin problems can be overcome by using skin treatments that contain antioxidant compounds so that oxidation reactions derived from free radicals can be inhibited (Halliwell and Gutteridge, 2000). Skin care that can overcome skin problems is body scrub preparation. Body scrub cream-based preparations consists of oil and water phase, emulgator, and abrasives. Oilseed press cake or residual product of nyamplung (tamanu) oil (Calophyllum inophyllum L.) has characteristics as an abrasiver and reported degree of hydrolysis that can counteract free radicals using the DPPH method through a % RSA value of 39.82%. Oilseed press cake of nyamplung will be developed as a raw material for the formulation of body scrub that have added value. Body scrub formulation was done by optimizing the emulgator material (stearic acid and triethanolamine) using Expert Design software D-Optimal and the optimal emulgator concentration was obtained (stearic acid 3% and triethanolamine 1%) and physical in stability of the optimum formulation is tested in 28 days in 1,2,3 and 4 week at room temperature by looking at the parameters of organoleptic physical properties, pH, viscosity, spreadability, and adhesion test. Based on physicaly examination, it showed that the formula of oilseed press cake of nyamplung body scrub for 28 days at room temperature is a semi-solid, brown color and smells of apple, pH value is 7,647 ± 0.128; the viscosity value is 3.633.33 ± 152.75 dPas; spreadability is 3,87 ± 0.20 cm, and adhesiveness is 2,3 ± 0,04 second.

Abstract
Most local governments in Indonesia experienced problems in developing pavements on expansive soil as observed in the damages to the road segment due to the conditions of the soil and excessive traffic loads. This has led to the rehabilitation of the road pavement by designing a continuous rigid structure without reinforcement. Therefore, this study aimed to analyse and evaluate the condition of a jointed plain concrete pavement (JPCP) structure without reinforcement based on the results of deflection and tensile stress. The process involved the application of Manual Road Pavement method to determine the pavement thickness as well as the use of analytical and numerical analysis to produce tensile and deflection values at CBR variations of 2% to 6%. Moreover, loads were applied at the edge and centre of the concrete plates and the results from the two methods of analysis were compared to determine the usefulness of different types of reinforced rigid pavement on the conditions of expansive soil subgrade. Meanwhile, the jointed plain concrete pavement analysis without reinforcement produced a 25 cm thick concrete plate and the thickness was further analysed analytically and numerically using variations in CBR values from 2% to 6%. The deflection and tensile stress values, however, met the maximum limit required.
Determining initial damage state of confined masonry wall
Authors: Safarizki H A , Marwahyudi  
Published: June 2021

Abstract
A masonry wall can withstand the compressive, tensile, and shear forces, besides that, a masonry wall can add rigidity to the building structure. The stiffness contributed by the masonry wall can influence the stiffness of the global structure. The contribution of stiffness to masonry walls is linear until the walls are damaged. The linear limit of the behaviour of masonry infill reinforced concrete portal can be used as the first criterion of damage (damage state). This study aims to determine the limit criteria for damage to reinforced concrete masonry wall buildings. The types of bricks used are normal bricks, Z bricks, Z hook bricks. The portal structure of masonry infill reinforced concrete was analyzed using the stiffness approach in the matrix formulation, where the wall stiffness was assumed to be a strut. The strut stiffness is determined based on the masonry panel shear test. The amount of lateral deformation on the portal when the internal shear force on the strut element reaches the wall shear strength limit is used as a limit for the linear behaviour of the masonry-filled reinforced concrete portal.

Abstract
Asphalt mixing plant (AMP) is a set of tools used to produce hot mix asphalt (HMA) in a location/place. This study is intended to determine the energy use of diesel fuel sets in the production process by measuring the energy use of both types of fuel including fuel consumption and energy, temperature, and the quantity of production from HMA in the AMP. The conclusion of this research is that changes in temperature and length of time of production will affect the use of diesel fuel and energy use, with the longer the production time and the temperature instability to heat the aggregate in the dryer, it will consume huge fuel and energy usage and the results of the calculation analysis were also obtained by producing a HMA weighing 130.640 tons requires consumption of diesel fuel of 1,477.25 liters which is equivalent to the fuel consumption of oil palm shell waste of 6.01 ton and also which is equivalent to energy use of 52,280.99 MJ, for each production of 1 ton of HMA required consumption of diesel fuel of 11.31 liters. Meanwhile, to increase 1°C requires 8.09 liters of diesel fuel consumption which is equivalent to energy use of 290.16 MJ.
Synchronization in coupled integer and fractional-order gauss map

Published: June 2021

AbstractNonlinear maps are often used to model dynamical systems in engineering and sciences. In some cases, the entire memory dictates the time evolution of the system. Fractional-order maps have been proposed to model such situations. In a spatially extended system, different parts of the system may respond to memory differently. We propose a mixed order system where one variable has a fractional-order evolution while the other variable has integer-order evolution. It models an inhomogeneous system where certain variables retain memory while certain others do not. It is also relevant to control problems where fractional or integer-order control may be useful for achieving the desired state. In two coupled gauss maps, we consider unidirectional as well as bidirectional coupling. Bifurcation diagram of the system has been studied for various values of fractional-order parameter α. In particular, we study synchronization in these systems.
On properties of non-markovian random walk in one dimension
Authors: Warambhe Manoj C. , Gade Prashant M. 
Published: June 2021

Abstract
We study a strongly Non-Markovian variant of random walk in which the probability of visiting a given site i is a function f of number of previous visits v(i) to the site. If the probability is inversely proportional to number of visits to the site, say f(i)=1/(v(i)+1)α the probability distribution of visited sites tends to be flat for α>0 compared to simple random walk. For f(i)=exp(-v(i)), we observe a distribution with two peaks. The origin is no longer the most probable site. The probability is maximum at site k(t) which increases in time. For f(i)=exp(-v(i)) and for α>0 the properties do not change as the walk ages. However, for α<0, the properties are similar to simple random walk asymptotically. We study lattice covering time for these functions. The lattice covering time scales as Nz, with z=2, for α ≤ 0, z>2 for a >0 and z<2 for f(i)=exp(-v(i)).

Published: June 2021

Abstract
In the present work, positional Isomerism is studied in the binary mixtures of n-propyl alcohol and Iso-propyl alcohol in nitrobenzene as the common solvent. Ultrasonic velocity and attenuation measurements using pulse–echo technique operated at 10 MHz have been taken at various concentrations of both alcohols in nitrobenzene, from 283.15K - 293.15K. It is observed that both the systems exhibit critical nature and show non-linear variation both in ultrasonic velocity of propagation and attenuation. Ultrasonic attenuation at lower concentrations of n-propyl alcohol in nitrobenzene reveals the dominant structural relaxation as compared to that of Iso-propyl alcohol in nitrobenzene.

The agglomeration of the submicron sized crystallites resulted into formation of porous electrode layer is realized from scanning electron microscopy. The dcconductivity results showed maximum σ for x = 0.2, which also exhibited minimum activation energy.

Abstract
The europium ion (Eu3+) is well acknowledged and more popular for its strong luminescence when it is compared with other RE ions. Here we report the comparative study of electrospun polymer nanofibers by using europium and europium complex Eu(TTA)3phen by electrospinning technique. Electrospun fibers of Europium chloride and Europium complex Eu(TTA)3phen were prepared by using polymer PVDF to study the photoluminescence properties. Photoluminescence spectra of these electrospun nanofibers show very high intense red emission because of the strong hypersensitive behaviour of the 5D0 → 7F2 transition. These electrospun nanofibers are very much useful in the latest technology of Smart Textiles, for developing protective fabrics with thermal comfort. These fabrics also used to defend from wide variety of environmental hazards. This paper highlights the promising applications of electrospinning for developing protective fabrics and also shows the potential application in various polymer optoelectronic devices.

Published: June 2021

Abstract
In this work, we synthesized the Tb3+ and Eu3+ doped α-Ba3Y(BO3)3 phosphor using the solution combustion method. Using the powder XRD pattern and FTIR low-temperature phase of α-Ba3Y1-X(BO3): xTb3+& Eu3+ was confirmed. Element composition with percentage was verified by FE-SEM-EDS. Stoke’s shift values were calculated which confirms the high thermal stability of the phosphor& its use in high power WLED. Photoluminescence study at room temperature was done. Intrinsic absorption due to the 4f-4f transition of Eu3+ results intense red emission from α-Ba3Y1-X(BO3): xEu3+ makes it suitable for pc-WLED and confirms the Centro-inversion symmetry site of Eu3+ in the host. Green emission at NUV excitation from Ba3Y1-X(BO3): xTb3+ results from cross-relaxation of Tb3+ in a host. The concentration quenching reason for both activators was investigated by calculating and comparing critical distance. The purity of luminescence color was confirmed by plotting CIE-chromaticity co-ordinates on CIE-Color gamut. The entire work confirms the importance of synthesized phosphor along with previously reported same host materials. The reported phosphor may be suitable for NUV converted WLED, wavelength conversion devices, and high power RGB –WLED.

Abstract
In this review paper, we discuss about photoluminescence emission of Gd3+ in various inorganic phosphors. Narrow band UVB (NB-UVB) emission of Gd 3+ in 312-315 nm is well sought after in medical field to treat photo-responsive diseases like atopic dermatitis, vitiligo, psoriasis, etc. However, this 4f-4f, 6Pj → 8S7/2 intra-configurational transition of Gd3+ is weak and hence needs to be sensitized. Suitable sensitizers like Bi3+, Pr3+ are found to enhance the PL emission of Gd3+. Such phosphors with sensitized Gd3+ emission is highly suitable for phototherapy lamps.
