Abstract
This paper proposes an active actuator based on giant magnetostrictive composite pendulum for vibration isolation, laying the foundation for vertical micro-vibration isolation. The performance of a single-stage pendulum vibration isolation system can be improved by increasing the pendulum length, along with the influence of the environment on the system increases. In precise experiments, effective isolation of vertical micro-vibration improves the accuracy of the experiments. Interference caused by micro-vibration can be attenuated by designed magnetostrictive actuators. Then, a suspension actuator consists of a composite pendulum and a driving device is designed. The composite pendulum is composed of a quartz fiber coated with a giant magnetostrictive material (GMM). The GMM can achieve the desired small strain in a designed magnetic field. GMM is applied on a quartz fiber to form a composite pendulum. Therefore, low-frequency active vibration isolation of single pendulum is realized. Compared with the passive vertical vibration isolation system, the system gets better vibration isolation and anti-interference ability. Compared with the traditional active vertical vibration isolation system, it has the advantages of system simplification, high integration and high sensitivity.

Published: October 2019

Abstract
The flow field in the rotating drum of dynamic oil-water hydrocyclone separator is a high turbulent shear flow field. Oil droplets are easily deformed, broken and even emulsified when the oil droplets enter the drum. Because oil droplets are affected by high turbulent shear flow field. If oil-water emulsification occurs, the separation performance of dynamic oil-water hydrocyclone will be dramatically reduced. Therefore, it is an important subject to study dynamic oil-water hydrocyclone separator and improve its separation performance to carry out oil drop deformation model research, which can reduce oil drop deformation and fragmentation and formulate measures to avoid oil-water emulsification.

Abstract
The aim of the study was to investigate the effect of dietary inclusion of purslane meal (Portulaca oleraceae) and sardines fish oil as a source of omega-3 fats on production performance and carcass quality of broiler chickens. A total of 180 one-day old unsexed Cobb broiler chickens were used in this study. The broilers were randomly allocated into 30 pens with each pen consisted of 6 birds. The pens were randomly assigned to five dietary treatments with 6 replicates (36 birds per treatment). The diets were prepared from a basal diet (P0). The experimental diets were formulated by supplementing the basal diet containing 1.5% sardines fish oil and levels of purslane meal 0 (P1), 6 (P2), 12 (P3), and 18.0% (P4). Water and diets were provided ad libitum for a period of 35 days. Data production parameters were recorded weekly. The data were analysed using analysis of variance (ANOVA). Differences between treatment means were further analysed using Duncan’s New Multiple Range Test. Results showed that there were no significant effects on production parameters and carcass weight by adding of dietary purslane meal up to a level of 12%. However, supplementation of 18% purslane meal (P4) resulted in a decrease in body weight from 1718 g (P0) to 1278 g (P4) and in carcass weight from 1139 g (P0) to 811.5 g (P4). It was concluded that dietary levels of purslane meal up to a level of 12% didn’t have negative effect on production performance and carcass quality of broiler chickens.

Abstract
Utilization Oxisol as plant growth media for sorghum is still limited. The main problems of the cultivation in Oxisol are low pH, high soluble form of Al, Mn, Fe, low organic matter (OM) and lack of nutrients especially P. The purpose of the present research was to examine the effect of arbuscular mycorrhiza (AM) and OM type toward the growth and yield of sorghum on Oxisol Tuntang. The pot experiment was conducted in greenhouse using factorial completely randomized design with two factors of AM inoculation and OM type with three replications. The first factor was inoculation of AM: without and with AM inoculation. The second factor was OM type: without OM, elephant grass compost, cow dung compost, worm castings and goat manure. The inoculation of AM in interaction with OM significantly increased AM colonization, spore density, leaf number, dry weight, water uptake, P concentration, P uptake and grain mass. Interaction of AM with worm castings and interaction of AM with goat manure indicated the same higher effect on sorghum growth and yield, compared with the interaction of AM with elephant grass compost and interaction of AM with cow dung compost. The control treatment showed the lowest plant performance.

AbstractIn this study, panelist acceptance level, physical, and chemical properties of dark chocolate bar enriched with kaffir lime (Citrus hystrixDC.) leaf essential oil (0.25%, 0.5%, and 0.75%) were studied. The addition of kaffir lime leaf essential oil in dark chocolate bar is aimed to enrich the content of functional compounds in dark chocolate and is expected to create an Indonesian chocolate signature. The results showed that panelist acceptance level decreased with increasing concentration of kaffir lime leaf essential oil added in parameters of aroma, taste, and overall, thus, the highest panelists acceptance was dark chocolate bar with the addition of 0.25% kaffir lime leaf essential oil. The addition of various formulations of kaffir lime leaf essential oil showed a decrease in hardness significantly and the color differences between dark chocolate with and without addition of kaffir lime leaf essential oil were very small. The addition of 0.25% kaffir lime leaf essential oil increased the moisture content and antioxidant activity in dark chocolate bar significantly. Major compounds detected in GC-MS analysis of dark chocolate bar with the addition of 0.25% kaffir lime leaf essential oil were theobromine, citronellal, caffeine, and vanillin.

Abstract
Legumes are often used as a source of natural antioxidant. Elicitation is a promising alternative way of improving antioxidant compounds in legumes sprouts, such as flavonoid compound. NaCl stress can be used as one of abiotic elicitation that induced non-enzymatic defense in a plant, thus increases secondary metabolites which enhance the antioxidant capacity. However, its effects on cowpea (Vigna unguiculata) germination need to be more studied. In this study, we germinated cowpea under increasing salinity (0, 50, 100, 150mM NaCl) to investigate its effect on the total flavonoid content and antioxidant activity (radical scavenging activity and reducing power). Total flavonoid content and radical scavenging activity of cowpea sprouts increase along with increasing NaCl concentration. Meanwhile, only 150mM NaCl showed significantly higher reducing power among other concentrations. Total flavonoid content have a high correlation with radical scavenging activity (r=0, 962; p<0, 01) but not correlated with reducing power (r=0, 137; p>0, 05). This research results proved that elicitation using 150mM NaCl could be used as one of the strategies to enhance bioactive compound and antioxidant activity in legumes, thus increasing its potential to be developed as an antioxidant-based functional food.

Abstract
Seasoning flour was a food commodity that has a good market trend but currently the raw materials were still dominated by wheat flour that has been known as the triggering agent of some allergic disease. So in order to reduce the domination of wheat flour as raw material of the seasoning flour, an innovation of seasoning composite flour made from non-wheat flour that have suitable characteristics is needed. The objective of this study were to determine the chemical characteristics of seasoning composite flour that made from white sweet potato, rice and tapioca flours, and to determine and characterize the sensory profile of the best seasoning composite flour which was chosen using weighting test. The seasoning composite flour made using 9 formulas contain 13.261 - 14.089% water; 4.467 – 5.729% ash; 1.238 – 2.018% fat; 4.324 – 5.838% protein; 74.371 – 74.863% carbohydrate; 72, 781 – 75.613% starch; 21.904 – 25.760% amylose and 0.086 – 0.499% crude fiber. The best formula of seasoning composite flour has 30% tapioca flour, 30% rice flour and 40% white sweet potato flour ratio. The best one contains 13.261% water; 5.728% ash; 1.194% fat; 4.646% protein; 74.427% carbohydrate; 72.781%starch; 21.904% amylose and 0.499% crude fiber. Its sensory characteristic is significantly different from the commercial seasoning flour and overall get hedonic score 3.76 which means neutral.

Abstract
Physical properties (water holding capacity, cohesiveness, chewiness, springiness) and sensory characteristics (cohesiveness, chewiness, springiness and overall) of little tuna fish balls that substituted with arrowroot flour and added with sodium tripolyphosphate (STPP) were investigated. Substituted little tuna fish ball was added with 0%; 0.1%; 0.2%; 0.3% of sodium tripolyphosphate. Results of this study showed that the addition of sodium tripolyphosphate increased water holding capacity, cohesiveness, chewiness, and springiness parameters with respect to better textural properties of substituted little tuna fish balls (p<0.05). Sensory evaluation test showed that overall, substituted little tuna fish balls with 0.1% addition of STPP were the most favored by panelists. Water holding capacity, cohesiveness, chewiness, and springiness parameters of substituted little tuna fish balls added with 0.1% of STPP were increase up to 4.7%, 9.1%, 8.6%, and 2.0%, respectively. The multiple comparison tests showed that color, odor, flavor parameter of substituted little tuna fish balls added with sodium tripolyphosphate were relatively the same level.

Abstract
The aim of this study was to investigated the characteristic of chemical, physical, functional, and sensory properties of the fish balls with substitution rice bran flour. Substitution of rice bran flour and tapioca as fish ball fillers used in this research were 25:75, 40:60, 55:45, and 100:0 as a control. The result showed that the substitution of rice bran affected the chemical, functional, physical and sensory characteristics of eastern little tuna fish balls. The substitution of tapioca flour with rice bran flour as fillers in eastern little tuna fish ball could increase moisture, ash, fat, and protein content. In this study, antioxidant activity, vitamin E, and WHC of eastern little tuna fishballs were also increased. Texture properties (cohesiveness, chewiness, springiness) of eastern little tuna fish ball affected by the substitution of rice bran flour. Substitution of 25% rice bran and 75% tapioca flour as fillers in eastern little tuna fish ball was more acceptable than another formula. The moisture, ash, fat, protein, and total starch content of the eastern little tuna fish ball substituted 25% rice bran and 75% tapioca flour were 68, 07%; 6, 53%; 1, 47%; 38, 12%; and 41, 51%, respectively. Sensory analysis of the eastern little tuna fish ball substituted 25% rice bran and 75% tapioca flour formula showed that it had a brownish color, not-strong-fishy aroma, a slightly weaker fishy flavor, a rather strong rice bran flavor, and slightly weak texture.

Abstract
We propose a specific composition of a beam of a piezoelectric dielectric layer sandwiched between two nonpiezoelectric semiconductor layers. A one-dimensional theoretical model is established for the bending of the beam with shear deformation. A theoretical analysis of a cantilever of such a beam under an end shear force is performed. Results show that an axial electric field develops in the beam because of the shear deformation accompanying bending via the piezoelectric constant e
15. The axial electric field drives the charge carriers to the two ends of the beam. Thus the proposed composite beam can be used as a new and basic structure with potential applications in piezotronics when the shear force is present or dominant, differing from the homogeneous beam and the composite beam using e

, while demonstrating its functionality through a prototype solid-state Ti/La2LiHO3/TiH2 battery. In this study, we probe the atomistic motion of La2LiHO3 obtained by the promising halide salt flux method, via a combination of deep inelastic neutron scattering (DINS) and ab initio lattice dynamics (LD) calculations verified by vibrational inelastic neutron spectroscopy (INS). We successfully describe the measured momentum distributions from DINS via our LD calculations, without observing any diffusion activation over the temperature range reported by Kobayashi et al. This observation is corroborated by model predictions from our LD study, which reveals that the hydride anions remain bound within a 3D-harmonic potential. We conclude that with the current synthesis parameters, the method produces a vacancy free lattice, and that a necessary ingredient for diffusive motion of H- is the presence of a large population of vacancies. Based on the harmonic prediction for the hydrogen kinetic energy, we derive a picture of the evolution of the effective bonding potential for the hydride anions, and link this to the dynamics associated with decomposition of the oxyhydride.
Chemical and structural stability of superconducting In5Bi3 driven by spin–orbit coupling

Abstract
Relativistic effects play a prominent role in many electronic material properties such as the Rashba and Dresselhaus spin splitting in inversion asymmetric crystals, or the bulk band gap in topological insulators. By contrast, macroscopic material properties are typically not connected to relativistic phenomena. As an exception to this rule, we show that the macroscopic chemical and structural properties of superconducting In5Bi3 are driven by relativistic physics. In the non-relativistic limit In5Bi3 decomposes into elemental indium and bismuth, but the inclusion of relativistic spin–orbit coupling chemically stabilizes the In5Bi3 stoichiometry. Similarly, the structural stability of tetragonal In5Bi3 is driven by the spin–orbit interaction, which eliminates a phonon instability present in the non-relativistic limit. Low-temperature resistivity and heat capacity measurements show that In5Bi3 is a strong coupling superconductor, with a superconducting critical temperature of 4.2 K and a superconducting critical field of 0.3 T. The unconventional interplay between relativity with chemistry and structure, together with the presence of superconductivity, make In5Bi3 a versatile material that provides, for example, a simple model for the study of strong coupling superconductivity in quasiperiodic crystals.
Fatal Prescription
Authors: Stear Nils-Hennes 
Published: October 2019

Abstract
Ethicism is the most comprehensively defended answer to the question regarding whether ethical properties determine aesthetic properties in artworks. According to ethicism, aesthetically relevant ethical flaws in artworks count as aesthetic flaws and aesthetically relevant ethical merits count as aesthetic merits. In this paper, I argue that ethicism’s most significant argument, the Merited Response Argument (MRA) (and other moralist arguments like it) suffers from an ambiguity that makes it either unsound or uninteresting. Specifically, the notion of an artwork’s ‘prescribing’ a response, central to MRA, is ambiguous between merely attempting to elicit a response from appreciators as appropriate to a work, and endorsing a response as appropriate to relevant parts of the actual world. While the first sense of ‘prescribe’ does the aesthetic work, the second does the ethical.

Abstract

Objective
Variability in recovery time following sport-related concussion (SRC) is poorly understood. We explored the utility of brief mood, anxiety, and sleep questionnaires as postinjury predictors of SRC symptom clearance in adolescents.

Method
At initial visit 0–2 weeks postinjury, concussed athletes aged 12–18 years self-reported injury/medical factors (prior concussion, loss of consciousness, amnesia, and concussion symptom severity) and were administered psychological symptom measures. At 3 months, medical record review determined return-to-play (RTP) date. Subjects were divided into two datasets, with the first utilized for developing cutoff scores and then validated with the second dataset.

Results
A total of 64% of the 141 participants had early RTP (within 21 days postinjury), and 23% had late RTP (postinjury day 30 or later). The Generalized Anxiety Disorder Screener (GAD-7, M = 2.1, SD = 3.1) was the only significant predictor (p = .001), with a 1.4-fold [95% CI 1.2–1.8] increased risk for every point. No other factors in the full model discriminated recovery groups (ps &gt; .05). Receiver operating characteristic curve analysis derived a GAD-7 cut score ≥3 (sensitivity= 56.7%, specificity = 74.2%, AUCs = 0.63–0.79, ps &lt; .001).

Conclusions
Postconcussion anxiety symptoms may help identify individuals at increased risk for prolonged recovery.
