Abstract

An mapping of the potential Manganese mining zones has been done at Naip areas of the South Central Timor Regency using geomagnetic method. The purpose of this study was to determine the bedding structure and the subsurface patterns of rocks distribution that suspected contain manganese. The result of research were interpreted qualitatively and quantitatively. Qualitative interpretation shows that the low anomaly between -10 to <50 nT is mostly in the southern part and the high anomaly is ≥ 50 to 220 nT, generally in the northern part of the study area. The low anomaly is interpreted as clay and high anomaly is interpreted as limestone associated with manganese and metamorphic rocks. For quantitative interpretation, the presence of manganese is suspected to be associated with limestone at a depth of 6.2-100 m in body 1A incision 1 (A-A1) with susceptibility value 0.008116, body 1B incision 2 (B-B1) which has susceptibility value 0.001967 and body 1C incision 3 (C-C1) for the susceptibility value of 0.006407. Body 1A incision 1 (A-A1) is spread from west to northeast direction, body 1B incision 2 (B-B1) starts south to north and body 1C incision 3 (C-C1) is southwest toward northeast.

Abstract Marungga tree is one of the plants that have great benefits. The leaves themselves can be transformed into nutritional supplements and also as a cosmetic base ingredient. Marungga leaves themselves can be used as a powder for further processing into various needs. Before being made into powder, the leaf must be dried beforehand. Manual drying so far requires a long time and is not hygienic. In this study the results were obtained, the drying process for19 hours obtained the result of humidity reduction could not be done quickly. This is because the temperature in the room is not able to heat the surrounding air quickly so the drying process tends to be slower. With a drying load of 20 kg of raw Marungga leaves, about 3 kg of dried leaves are obtained.Keywords: marungga; heat transfer; cabinets

Abstract
In recent years, singular value decomposition (SVD)-based clutter filters have received widespread attention in ultrasound flow imaging owing to their high performance over traditional clutter filters in suppressing clutter signals. The excellent performance of the SVD clutter filter depends on its adaptive nature. The SVD clutter filter adaptively rejects echoes from slowly moving clutters, allowing visualization of echoes from blood cells. Owing to this property, the SVD filter works well throughout a cardiac cycle. Recently, deep neural networks have been used for a variety of tasks. The adaptive nature of deep neural networks would be beneficial for clutter filtering in ultrasonic blood flow imaging. In the present study, we conducted a preliminary study on clutter filtering using a long short-term memory neural network. Experimental results suggested that the proposed deep-learning clutter filter achieved a comparable performance than SVD one in terms of contrast values.
Self-bending airborne ultrasound beam using a binary lens based on the Airy function
Authors: Yamamoto Nagisa , Nomura Hideyuki 
Published: March 2021

Abstract
Self-bending of a beam of sound was previously achieved by an acoustic metasurface that modified the amplitude and phase modulations. However, fabricating a fine-structured device for ultrasound is difficult because it has a short wavelength. In this paper, we propose a simple binary acoustic lens for a self-bending ultrasound beam in air at 40 kHz. The lens has transparent and opaque areas and was designed using the Airy function. The beam bending was evaluated by simulations and experiments. The simulations showed that the proposed lens achieved beam self-bending, although the concentration of energy in the main beam was inferior to that for phase-coded modulation. The experiments demonstrated that self-bending is feasible using a binary lens made of a polypropylene sheet, and the measured sound fields agreed well with the simulations. These results suggest that a self-bending beam of ultrasound is possible with a lens having a simple binary structure.

Introduction. Ocular myasthenia gravis (OMG) is an autoimmune disease which is characterized by weakness of extraocular muscles, levator palpebrae and orbicularis oculi, resulting in ptosis and binocular diplopia. Nearly all patients present with eyelid and extra ocular muscles involvement. Approximately 30% to 80% of patients with OMG experience a conversion to generalized myasthenia gravis (GMG) within 2 years. There are not only have ptosis and diplopia but also limb weakness,bulbar symptoms, or even respiratory failure.
Objective. To observe the clinical features of OMG to GMG and risk factors and median time to conversion of OMG to GMG of myasthenia gravis patients in Mohammad Hoesin General Hospital Palembang.
Method. This study is a cohort retrospective study and the data were collected from the medical records of 91 patients who were registered as myasthenia gravis patients during September 2018 to March 2020. Sosiodemographic and clinical characteristics, including onset of OMG to GMG, history of smoking, presence of thymic abnormalities, and medications received were reviewed retrospectively.
Result. A total of 91 OMG patients were observed in this study with 32 (35,2%) patients converted from ocular myastenia gravis to general myastenia gravis. Median conversion time to GMG was 34 months. Risk factor for convertion cases of OMG to MGG was receiving immunosupressive agents(Risk: 14.7, 95% CI 4.83, 44.7), thymus hyperplasia (Risk: 3.36, CI 95% 0.33, 33.6), Female (Risk: 2.41, 95% CI 0.94, 6.17), Smoking (Risk: 1.56, 95% CI 0.31, 7.81).
Conclusion. Ptosis was the definitive sign for OMG in this study, with all patients had ptosis, thus it needs the colaboration from neuroophthalmologist and neurologist to diagnose and manage this case. Most of converted case was female and those who receive an immunosupressive agent therapy.
Ethos deseantes. Políticas del amor en Francisco Brines y José A. Goytisolo
Authors: Romano Marcela 
Published: March 2021

Este trabajo se centra en algunos tramos de la poesía amorosa de Francisco Brines y de José Agustín Goytisolo, publicada (escrita o reescrita) a partir de 1986. Ambas voces espigan un ethos poético (Ballart 2005) cuyas performances deseantes transcurren entre la celebración del goce y la elegía, movimientos que invitan al lector a un pacto de confianza donde la persuasión del “orador” es eficaz en la medida en que asiente con la experiencia “común” o las expectativas de lectura habituales y las desvía, para enriquecerlas en perspectivas: en uno y otro caso, estas escrituras son diseñadas como un entramado polémico que pugna por contravenir las prácticas y representaciones del amor todavía dominantes dentro del imaginario español de la Transición y las décadas posteriores.

Published: March 2021

Se aborda el análisis del libro Mailu batekin: Biola batekin (1962), desconocido hasta ahora del importante poeta vasco Gabriel Aresti (1933-1975). Se analizan dos procesos, escritura y publicación, que no siempre van de la mano en su creación poética. El conocimiento y la edición de este libro nuevo han permitido cambiar algunas de las opiniones que se mantenían sobre él, sobre todo en lo que corresponde a la datación del símbolo de la piedra central en su poesía. Al tratarse de un libro coherente, el análisis permite dibujar de manera clara algunos ejes ideológicos del autor, y las claves de su pensamiento político y estético.
The item/order account of word frequency effects: Evidence from serial order tests
Authors: Neath Ian , Quinlan Philip T. 
Published: March 2021

AbstractAccording to the item/order hypothesis, high-frequency words are processed more efficiently and therefore order information can be readily encoded. In contrast, low-frequency words are processed less efficiently and the focus on item-specific processing compromises order information. Most experiments testing this account use free recall, which has led to two problems: First, the role of order information is difficult to evaluate in free recall, and second, the data from free recall show all three possible patterns of results: memory for high-frequency words can be better than, the same as, or worse than that for low-frequency words. A series of experiments tested the item/order hypothesis using tests where the role of order information is less ambiguous. The item/order hypothesis predicts better performance for high- than low-frequency words when pure lists are used in both immediate serial recall (ISR) and serial reconstruction of order (SRO) tests. In contrast, when mixed (alternating) lists are used, it predicts better performance for low- than for high-frequency words with ISR tests, but equivalent performance with SRO tests. The experiments generally confirm these predictions, with the notable exception of a block order effect in SRO tasks: When a block of low-frequency lists preceded a block of high-frequency lists, a high-frequency advantage was observed but when a block of high-frequency lists preceded a block of low-frequency lists, no frequency effect was observed. A final experiment provides evidence that this block order effect is due to metacognitive factors.

Abstract
The underlying distribution of galaxies’ dust spectral energy distributions (SEDs) (i.e., their spectra reradiated by dust from rest-frame ∼3 μm to 3 mm) remains relatively unconstrained owing to a dearth of far-IR/(sub)millimeter data for large samples of galaxies. It has been claimed in the literature that a galaxy’s dust temperature—observed as the wavelength where the dust SED peaks (λ
peak)—is traced most closely by its specific star formation rate (sSFR) or parameterized “distance” to the SFR–M
⋆ relation (the galaxy “main sequence”). We present 024 resolved 870 μm ALMA dust continuum observations of seven z = 1.4–4.6 dusty star-forming galaxies chosen to have a large range of well-constrained luminosity-weighted dust temperatures. We also draw on similar-resolution dust continuum maps from a sample of ALESS submillimeter galaxies from Hodge et al (2016). We constrain the physical scales over which the dust radiates and compare those measurements to characteristics of the integrated SED. We confirm significant correlations of λ
peak with both L
IR (or SFR) and ΣIR (∝SFR surface density). We investigate the correlation between log10(λ
peak) and log10(ΣIR) and find the relation to hold as would be expected from the Stefan–Boltzmann law, or the effective size of an equivalent blackbody. The correlations of λ
peak with sSFR and distance from the SFR–M
⋆ relation are less significant than those for ΣIR or L
IR; therefore, we conclude that the more fundamental tracer of galaxies’ luminosity-weighted integrated dust temperatures are indeed their star formation surface densities in line with local universe results, which relate closely to the underlying geometry of dust in the interstellar medium.
Measuring Magnetization with Rotation Measures and Velocity Centroids in Supersonic MHD Turbulence
Authors: Xu Siyao , Hu Yue 
Published: March 2021

Abstract
The interstellar turbulence is magnetized and thus anisotropic. The anisotropy of turbulent magnetic fields and velocities is imprinted in the related observables, rotation measures (RMs), and velocity centroids (VCs). This anisotropy provides valuable information on both the direction and strength of the magnetic field. However, its measurement is difficult, especially in highly supersonic turbulence in cold interstellar phases, due to the distortions by isotropic density fluctuations. By using 3D simulations of supersonic and sub-Alfvénic magnetohydrodynamic (MHD) turbulence, we find that the problem can be alleviated when we selectively sample the volume filling low-density regions in supersonic MHD turbulence. Our results show that in these low-density regions the anisotropy of RM and VC fluctuations depends on the Alfvénic Mach number as

. This anisotropy−M
A relation is theoretically expected for sub-Alfvénic MHD turbulence and confirmed by our synthetic observations of 12CO emission. It provides a new method for measuring the plane-of-the-sky magnetic fields in cold interstellar phases.
On-disk Solar Coronal Condensations Facilitated by Magnetic Reconnection between Open and Closed Magnetic Structures

Published: March 2021

Abstract
Coronal condensation and rain are a crucial part of the mass cycle between the corona and chromosphere. In some cases, condensation and subsequent rain originate in the magnetic dips formed during magnetic reconnection. This provides a new and alternative formation mechanism for coronal rain. Until now, only off-limb, rather than on-disk, condensation events during reconnection have been reported. In this paper, employing extreme-ultraviolet (EUV) images of the Solar Terrestrial Relations Observatory (STEREO) and Solar Dynamics Observatory (SDO), we investigate the condensations facilitated by reconnection from 2011 July 14–15, when STEREO was in quadrature with respect to the Sun–Earth line. Above the limb, in STEREO/EUV Imager (EUVI) 171 Å images, higher-lying open structures move downward, reconnect with the lower-lying closed loops, and form dips. Two sets of newly reconnected structures then form. In the dips, bright condensations occur in the EUVI 304 Å images repeatedly, which then flow downward to the surface. In the on-disk observations by SDO/Atmospheric Imaging Assembly (AIA) in the 171 Å channel, these magnetic structures are difficult to identify. Dark condensations appear in the AIA 304 Å images, and then move to the surface as on-disk coronal rain. The cooling and condensation of coronal plasma is revealed by the EUV light curves. If only the on-disk observations were be available, the relation between the condensations and reconnection, shown clearly by the off-limb observations, could not be identified. Thus, we suggest that some on-disk condensation events seen in transition region and chromospheric lines may be facilitated by reconnection.

Advanced design power units are distinguished by a high degree of digital transformation. Therefore, of particular interest are operator information (intelligent) support systems, which can reduce the workload on operating personnel as well as predict possible deviations long before they evolve into severe emergencies.
The article analyzes the current standard process documentation that requires solutions to support the operator and determines the list of system functions that should be provided to improve the safety level of nuclear power plants. A brief overview of the world experience in implementing such solutions is also provided.
As an example of the further development of operator support systems, the authors consider the operator information support system (OISS), which is being developed at the NvNPP pilot unit with the VVER-1200 reactor. The OISS functions will make it possible to fulfill the requirements of standard process documentation that are currently not implemented in the power unit design.
The key features of the OISS under development are step-by-step interactive procedures and the unit software model. The authors provide a brief description of the power unit software model and consider several examples of its practical application as part of the OISS to improve design solutions and optimize automatic process control. In the years ahead, it is proposed to implement the OISS at power units under construction in order to reduce the information overload of operators and create conditions for a step-by-step increase in the automation level of the power unit control.
