Virgin Coconut Oil (VCO) yang merupakan salah satu produk olahan kelapa yang memiliki banyak manfaat kesehatan sulit dikonsumsi secara langsung karena rasanya yang berminyak (oily). Oleh karena itu, untuk membuatnya enak dikonsumsi, VCO dibuat dalam bentuk minuman emulsi. Pada penelitian ini, minuman emulsi VCO ditambahkan dengan jahe merah dan sereh yang bertujuan untuk menyelidiki pengaruh penambahan jahe merah dan sereh pada karakteristik fisik, kimia, aktivitas antioksidan, dan tingkat kesukaan panelis terhadap minuman emulsi VCO. Konsentrasi jahe merah dan sereh divariasikan: 100% jahe merah, 100% sereh, 50% jahe merah : 50% sereh, 75% jahe merah : 25% sereh, dan 25% jahe merah : 75% sereh. Hasil menunjukkan bahwa konsentrasi jahe merah dan sereh mempengaruhi warna minuman emulsi VCO yang dihasilkan. Penggunaan gum arab (7%) menghasilkan minuman emulsi VCO yang stabil selama waktu pengamatan 7 hari. Total gula (% sukrosa) berkisar pada 26,00%-28,67%. Total fenol dan bilangan peroksida minuman emulsi berkisar dari 20,92 – 28,61 mg GAE/ g sampel dan 0,08-0,79 mg ekuivalen O2/kg. Pada konsentrasi 15 ppm, aktivitas antioksidan minuman emulsi berkisar antara 58,58% - 71,20%. Minuman emulsi dengan penambahan 100% jahe merah paling disukai dalam aroma, warna, dan penampakannya, sedangkan minuman emulsi dengan penambahan 75% jahe merah dan 25% sereh yang paling disukai rasanyaVirgin Coconut Oil (VCO) as one of the coconut products with many health benefits hard to be consumed directly because of its oily taste. Therefore, to make it more tastier to consume, VCO will be made in form of emulsion drink. In this research, VCO emulsion drink will be added with red ginger and lemongrass to investigate the addition effect of these spices on the physical, chemical characteristic, antioxidant activity, and panelist preference rate of its emulsion drink. The concentrations of red ginger and lemongrass were varied : 100% red ginger, 100% lemongrass, 50% red ginger : 50% lemongrass, 75% red ginger : 25% lemongrass, and 25% red ginger : 75% lemongrass. The result shows that the concentration of red ginger and lemongrass affected the color of the emulsion drink. The addition of arabic gum (7%) produced a stable emulsion drink during the observation time of 7 days. The sucrose percentage of the emulsion drink is 26,00% to 28,67%. The average of total phenol and peroxide numbers in the emulsion drinks was 20,92 to 28,61 mg GAE /g sample and 0,08-0,79 mg equivalent O2 / kg. At a concentration of 15 ppm, the antioxidant activity of emulsion drinks ranged from 58,58% - 71,20%. VCO emulsion drinks with the addition of 100% red ginger were the most preferred in terms of aroma, color, and its appearance, while the addition of 75% red ginger and 25% lemongrass were the most preferred in taste

The weakening of national economic conditions due to the Covid-19 pandemic has an impact on economic conditions in the regions, including in Ende Regency. Restrictions on community activities have disrupted economic activity in all sectors, including the Micro, Small and Medium Enterprises (MSME) sector. This can be seen in the reduced trading activity at several market in Ende Regency. This study was conducted to find out how much impact the Covid-19 pandemic had on the economy in Ende Regency. The results showed that (1) the economic condition in Ende Regency prior to the Covid-19 Pandemic was sufficiently demonstrated by the low GRDP value of Ende Regency; (2) The Direct Cash Assistance (DCA) policy has an economic impact on the community but it is not yet very effective because there are still many people who do not receive DCA funds even though they meet the criteria as prospective DCA recipients; (3) The impact of the Covid-19 Pandemic on the community is experienced by business actors more than farmers and the biggest impact is on the decline in the income level of MSME actors; (4) Ende Regency's economic sustainability is in a less sustainable status in terms of economic, social and institutional aspects; (5) The dominant variables affecting the economic status of Ende Regency are (1) superior products and limited online marketing; (2) public understanding of the governance that occurs and (3) there is no marketing agency in Ende Regency.

Published: August 2022

Abstract
Conventional direct current (DC)-poling and three different types of pulse-poling were performed on MnO-added Na0.55K0.45NbO3 (NKN) ceramics. While NKN with DC-poling at 4.0 kV mm−1 for a poling time (t
p) of 100 s showed a piezoelectric charge coefficient d
33 of 141.3 pC N−1, an almost equivalent d
33 (141.3 pC N−1) was recorded by pulse-poling in only 10 s under a unipolar electric field of 4.0 kV mm−1, with either triangular, or rectangular waveform. Especially when applying a triangular waveform, d
33 was enhanced remarkably with increasing the number of pulse cycles. In contrast, NKN ceramics poled by alternating current (AC) electric field showed a d
33 of less than 135 pC N−1 under any condition. Polarization–electric (P–E) field responses, and domain structure observations via scanning electron microscopy, showed the different poling behaviors for the various poling techniques. These results suggested that the pulse-poling method under unipolar electric field is an efficient poling procedure for NKN ceramics.

Abstract
The chemical composition dependence of the Bi(Mg0.5Ti0.5)O3 (BMT)-modified BaTiO3 (BT)-BiFeO3 (BF) ceramics fabricated by a solid-state synthesis was studied. The effects of BT/BF ratios and BMT concentration on the crystal structure, piezoelectric, and ferroelectric properties were investigated. The crystal structure study carried out under the synchrotron radiation X-ray diffraction revealed a change from rhombohedral structure to the pseudo-cubic structure when the BT contents were increased. A significant change in crystal structure and piezoelectric characteristics was confirmed by varying the BT/BF ratios. In contrast, the crystal symmetry remained unaffected by varying the BMT concentration, while tailoring of the piezoelectric and ferroelectric properties was revealed. Based on the analysis of the structural characteristics and overall electrical properties, the ceramics with modification of the BMT content along with BT/BF ratios could be applied as candidate materials for various practical applications.
A CENTRALIDADE METROPOLITANA EM PEDAÇOS: REFLEXÕES SOBRE OS NOVOS CENTROS E SUAS CENTRALIDADES
Authors: Da Silva Oséias Teixeira 
Published: August 2022

O presente texto busca ser uma contribuição para a pesquisa da centralidade metropolitana. O caminho de análise escolhido para isso foi o seguinte: em primeiro lugar realizamos algumas distinções teóricas importantes relacionadas a essa temática; em segundo lugar, com base nessa discussão, tratamos de um fenômeno recente dentro dessa temática que é o surgimento das chamadas “novas centralidades”. A primeira distinção tratada no texto é entre a centralidade da metrópole e a centralidade na metrópole. A centralidade da metrópole ocorre em escala regional, e a centralidade na metrópole na escala intra-urbana. A segunda distinção é entre o centro, realidade material originada a partir do processo de centralização, e a centralidade, capacidade de polarização de um centro a partir de sua configuração material. Com base nessas distinções buscamos em seguida tratar das características dos “novos centros” e da centralidade que os mesmos expressam confrontando essas características com os dos centros tradicionais.

Este artigo tem como objetivo mostrar os modos de dispersão urbana, a partir de dados originais do banco de dados BRASIpolis, associando as manchas dos aglomerados urbanos do Brasil aos dados populacionais de 2010. A abordagem a partir das formas espaciais produzidas requer discutir as palavras, em quatro idiomas, de acordo com o tipo de extensão do tecido urbano, comparando: forma, processo, força e conteúdo. Depois, quatro pontos de vista estão definidos para observar a dispersão urbana, com ênfase nas formas urbanas: escala de observação, padrões de ocupação do solo, ambiente rural e estruturas dos aglomerados. A relevância destas perspectivas é justificada pela descrição de exemplos de vários aglomerados selecionados na base BRASIpolis. O artigo é baseado em uma primeira aproximação do tema, para a escala brasileira, buscando levantar questões e propondo novos caminhos para a pesquisa, incluindo o desenvolvimento de dados retrospectivos para entender o processo de expansão urbana, no decorrer do tempo.

Abstract: Hakadohop is a term in the Ngaju Dayak language which means help, as one of the cultural values that believes in social life everyone needs each other. This study aims to describe the phenomenon of Hakadohop-based teacher development in improving teaching profesional competence during the Covid 19 pandemic in schools located in the DAS Kahayan. This study uses a qualitative approach with a multi-site study design. Data collection techniques using observation, interviews, and documentation studies. Data analysis used interactive patterns from Miles, Huberman, and Saldana. Checking the credibility of the data is done by triangulation and member checks. The results of the study indicate that the development of Hakadohop-based teachers in the new normal era has been going quite well. This can be seen from the Hakadohop- based teacher development mechanism which has had a positive impact on the online learning process by teachers. The support of the school and the involvement of parents in assisting the child's learning process from home are factors that support the smoothness of online learning; However, it is undeniable that internet network problems are still an obstacle in the implementation of online learning.
Short-term perceptual reweighting in suprasegmental categorization
Authors: Jasmin Kyle , Tierney Adam , Obasih Chisom , Holt Lori 
Published: August 2022

AbstractSegmental speech units such as phonemes are described as multidimensional categories whose perception involves contributions from multiple acoustic input dimensions, and the relative perceptual weights of these dimensions respond dynamically to context. For example, when speech is altered to create an “accent” in which two acoustic dimensions are correlated in a manner opposite that of long-term experience, the dimension that carries less perceptual weight is down-weighted to contribute less in category decisions. It remains unclear, however, whether this short-term reweighting extends to perception of suprasegmental features that span multiple phonemes, syllables, or words, in part because it has remained debatable whether suprasegmental features are perceived categorically. Here, we investigated the relative contribution of two acoustic dimensions to word emphasis. Participants categorized instances of a two-word phrase pronounced with typical covariation of fundamental frequency (F0) and duration, and in the context of an artificial “accent” in which F0 and duration (established in prior research on English speech as “primary” and “secondary” dimensions, respectively) covaried atypically. When categorizing “accented” speech, listeners rapidly down-weighted the secondary dimension (duration). This result indicates that listeners continually track short-term regularities across speech input and dynamically adjust the weight of acoustic evidence for suprasegmental decisions. Thus, dimension-based statistical learning appears to be a widespread phenomenon in speech perception extending to both segmental and suprasegmental categorization.
Test-retest reliability of a smartphone-based approach-avoidance task: Effects of retest period, stimulus type, and demographics

Published: August 2022

AbstractThe approach-avoidance task (AAT) is an implicit task that measures people’s behavioral tendencies to approach or avoid stimuli in the environment. In recent years, it has been used successfully to help explain a variety of health problems (e.g., addictions and phobias). Unfortunately, more recent AAT studies have failed to replicate earlier promising findings. One explanation for these replication failures could be that the AAT does not reliably measure approach-avoidance tendencies. Here, we first review existing literature on the reliability of various versions of the AAT. Next, we examine the AAT’s reliability in a large and diverse sample (N = 1077; 248 of whom completed all sessions). Using a smartphone-based, mobile AAT, we measured participants’ approach-avoidance tendencies eight times over a period of seven months (one measurement per month) in two distinct stimulus sets (happy/sad expressions and disgusting/neutral stimuli). The mobile AAT’s split-half reliability was adequate for face stimuli (r = .85), but low for disgust stimuli (r = .72). Its test–retest reliability based on a single measurement was poor for either stimulus set (all ICC1s < .3). Its test–retest reliability based on the average of all eight measurements was moderately good for face stimuli (ICCk = .73), but low for disgust stimuli (ICCk = .5). Results suggest that single-measurement AATs could be influenced by unexplained temporal fluctuations of approach-avoidance tendencies. These fluctuations could be examined in future studies. Until then, this work suggests that future research using the AAT should rely on multiple rather than single measurements.

AbstractIn this study, we present the first database of pictures and their corresponding psycholinguistic norms for Polish: the CLT database. In this norming study, we used the pictures from Cross-Linguistic Lexical Tasks (CLT): a set of colored drawings of 168 object and 146 actions. The CLT pictures were carefully created to provide a valid tool for multicultural comparisons. The pictures are accompanied by norms for Naming latencies, Name agreement, Goodness of depiction, Image agreement, Concept familiarity, Age of acquisition, Imageability, Lexical frequency, and Word complexity. We also report analyses of predictors of Naming latencies for pictures of objects and actions. Our results show that Name agreement, Concept familiarity, and Lexical frequency are significant predictors of Naming latencies for pictures of both objects and actions. Additionally, Age of acquisition significantly predicts Naming latencies of pictures of objects. The CLT database is freely available at osf.io/gp9qd. The full set of CLT pictures, including additional variants of pictures, is available on request at osf.io/y2cwr.
Long-term Evolution of Supercritical Black Hole Accretion with Outflows: A Subgrid Feedback Model for Cosmological Simulations

Abstract
We study the long-term evolution of the global structure of axisymmetric accretion flows onto a black hole (BH) at rates substantially higher than the Eddington value (

), performing 2D hydrodynamical simulations with and without radiative diffusion. In the high-accretion optically thick limit, where the radiation energy is efficiently trapped within the inflow, the accretion flow becomes adiabatic and comprises turbulent gas in the equatorial region and strong bipolar outflows. As a result, the mass inflow rate decreases toward the center as

. The global structure of the flow settles down to a quasi-steady state in millions of the orbital timescale at the BH event horizon, which is ≳10–100 times longer than that addressed in previous (magneto-)RHD simulation studies. Energy transport via radiative diffusion accelerates the outflow near the poles in the inner region but does not change the overall properties of the accretion flow compared to the cases without diffusion. Based on our simulation results, we provide a mechanical feedback model for super-Eddington accreting BHs. This can be applied as a subgrid model in large-scale cosmological simulations that do not sufficiently resolve galactic nuclei, and to the formation of the heaviest gravitational-wave sources via accretion in dense environments.
Debye-scale Solitary Structures in the Martian Magnetosheath

Published: August 2022

Abstract
We present an analysis of 450 solitary wave pulses observed by the Langmuir Probe and Waves instrument on the Mars Atmosphere and Volatile EvolutioN spacecraft during its five passes around Mars on 2015 February 9. The magnitude and duration of these pulses vary between 1 and 25 mV m−1 and 0.2–1.7 ms, respectively. The ambient plasma conditions suggest that these pulses are quasi-parallel to the ambient magnetic field and can be considered electrostatic. These pulses are dominantly seen in the dawn (5–6 LT) and afternoon-dusk (15–18 LT) sectors at an altitude of 1000–3500 km. The frequencies of these electric field pulses are close to the ion plasma frequency (i.e., f
pi ≤ f
ef ≪ f
pe), which suggests that their formation is governed by ion dynamics. The computer simulation performed for the Martian magnetosheath plasma hints that these pulses are ion-acoustic solitary waves generated by drifted ion and electron populations and their spatial scales are in the range of few ion Debye lengths (1.65–10λ
di). This is the first study to report and model solitary wave structures in the Martian magnetosheath.
Constraining the Ellipticity of the Newborn Magnetar with the Observational Data of Long Gamma-Ray Bursts

Published: August 2022

Abstract
The X-ray plateau emission observed in many long gamma-ray bursts (LGRBs) has been usually interpreted as the spin-down luminosity of a rapidly spinning, highly magnetized neutron star (millisecond magnetar). If this is true, then the magnetar may emit extended gravitational wave (GW) emission associated with the X-ray plateau due to nonaxisymmetric deformation or various stellar oscillations. The advanced LIGO and Virgo detectors have searched for long-duration GW transients for several years; no evidence of GWs from any magnetar has been found until now. In this work, we attempt to search for signatures of GW radiation in the electromagnetic observation of 30 LGRBs under the assumption of the magnetar model. We utilize the observations of the LGRB plateau to constrain the properties of the newborn magnetar, including the initial spin period P
0, dipole magnetic field strength B

, and the ellipticity ϵ. We find that there are some tight relations between magnetar parameters, e.g.,

ϵ

and

. In addition, we derive the GW strain for the magnetar sample via their spin-down processes, and find that the GWs from these objects may not be detectable by the aLIGO and Einstein Telescope (ET) detectors. For a rapidly spinning magnetar (P ∼ 1 ms, B ∼ 1015 G), the detection horizon for the advanced LIGO O5 detector is ∼180 Mpc. The detection of such a GW signal associated with the X-ray plateau would be a smoking gun that the central engine of a GRB is a magnetar.
