O conceito de “Pessoa com Deficiência” é construído historicamente e vem rompendo com a ótica que focava nas supostas “limitações” da PCD, refletindo sobre as diversas barreiras impostas pela coletividade e que impedem o pleno desenvolvimento de todos os cidadãos. O Minicurso “Articulação da Rede” criado por um grupo de alunos do nono período de Psicologia do UNI-RN surge como uma possibilidade de enfrentamento às barreiras encontradas nos serviços de atenção à saúde para PCD. O objetivo geral é apresentar as possibilidades de construção de ensino-aprendizagem em Direitos Humanos no Ensino Híbrido. Têm-se como objetivos específicos explicar o projeto, contribuir na capacitação sobre o tema das PCD, mostrar as Políticas Públicas de Atenção Psicossocial da Pessoa com Deficiência em Natal/RN, refletindo as fragilidades e expondo os serviços em atividade que garantem produção de saúde para PCD em Natal\RN. A metodologia utilizada é a Análise Crítica do Discurso fundamentada pela psicologia sócio-histórica. Os resultados apontaram como uma possibilidade de intervenção no campo. Intenta-se, ainda, para uma alternativa de capacitação e produção de conhecimento com pouco custo financeiro para a rede SUAS e SUS. As possíveis limitações são o baixo impacto a curto prazo e a limitação à esfera dos alunos do curso de psicologia do UNI-RN. Nossa experiência nos levou a considerar a importância de pensar metodologias ativas e estratégias de ensino-aprendizagem híbridas que propiciem contato com o campo de estudo.

Published: March 2022

La hibridación interploidal en Buchloe dactyloides se dificulta debido al aborto prematuro del embrión. Sin embargo, es posible generar híbridos interploidales utilizando un protocolo eficiente de rescate de embriones. El objetivo de este trabajo fue desarrollar un protocolo para generar híbridos interploidales de Buchloe dactyloides mediante rescate de embriones in vitro. Las plantas femeninas y masculinas usadas en esta investigación fueron cultivadas y desarrolladas en diferentes invernaderos, y el polen se transfirió de manera manual al estigma. Las cariópsides con embriones inmaduros fueron separadas a los 15, 20, 25 y 30 días después de la polinización y se desinfectaron con una solución de hipoclorito de sodio (Cloralex comercial 6 % de cloro activo p/v) diluído en agua (1:9 v/v) durante 10 minutos y en seguida se enjuagaron tres veces con agua destilada estéril. Posteriormente se realizó el cultivo in vitro y se transfirieron al cuarto de incubación a temperatura de 25±2º C con un fotoperiodo de 12 horas con lámparas luz de día y una intensidad de 3000 lux. El medio usado para el establecimiento fue el medio básico de Murashige y Skoog (1962) (MS-62) complementado con 1 mg L-1 de Benciladenina (BA). La mayor germinación in vitro (65 %) se logró en cariópsides separados a los 30 días después de la polinización. Sólo las plántulas del híbrido 2410.56 desarrolladas in vitro fueron transferidas a tratamientos para multiplicación complementados con hormonas. El mejor medio para la multiplicación de los embriones híbridos fue el MS-62 complementado con 1 mg L-1 de BA + 0.3 mgL-1 de ANA que produjo con 24.1 brotes por explante. Para el enraizamiento, número y longitud de raíces, el mejor tratamiento fue el MS-62 al 100% + 1 mgL-1 de AIA. Los resultados indican que es posible generar híbridos interploidales de zacate búfalo usando el rescate de embriones in vitro.

Published: March 2022

Abstract
As a wiring material for printed electronics (PE), copper is strongly needed instead of silver. For a sintering method of copper traces, we have developed the method using oxygen pump and atmospheric pressure plasma, and demonstrated the ink composed of nanoparticles can be sintered to bulk-like structure. In this study, we have improved the sintering system to make it effective especially for copper inks made of submicron particles. We have tried to increase the thickness of the sintered layer and decrease the resistivity by changing the power supply system of plasma discharge and increasing the plasma density. The improved system has successfully demonstrated that a copper trace at least 4 μm thick can be sintered and that the resistivity decreases to approximately 3.3 μΩ·cm. These results can lead to huge breakthroughs in PE based on copper.
Improving axial resolution of medical ultrasound images by using noise-robust broadband filter based on singular value decomposition

Published: March 2022

Abstract
Improving spatial resolution is a crucial issue in medical ultrasound. One of the improving methods is the post-processing of the received ultrasound RF signal. In the present paper, we proposed a design method for a noise-robust broadband filter based on the singular value decomposition of the received RF signal. To design a noise-robust filter, we proposed a logical method to determine the optimal truncated order of singular values, which was validated by applying the filter to noise-contaminated signals. Furthermore, the proposed filter applied to the wire phantom resulted in a better axial resolution than that obtained without the filter and with our previously designed Wiener filter.

Authors: Prinosa Vandra , Syaiful Saanin  , Ade Ricky Harahap  
Published: March 2022

Background. Head injury is still a major health problem that is a common cause of disability and death. Moderate head injuries are quite common with outcomes varying patient examination of neutrophils and lymphocytes is quite routinely carried out in health services and the combination of these two values has a stronger predictive value for assessing outcomes in patients because it describes an inflammatory reaction. The GOS is a commonly used scale for classifying patient outcomes. This study aimed to determine the relationship between the ratio of neutrophil-lymphocytes (RNL) to the Glascow outcome scale (GOS) in moderate head injury patients with intracerebral hemorrhage.
Methods. This study has a cross-sectional with samples from moderate head injury patients with CT scan images of intracerebral hemorrhage in Dr. M. Djamil Padang in 2021 and 2022. The data comes from medical records and observations of samples that meet the inclusion and exclusion criteria, 36 subjects participated in this study.
Results. Most of the subjects (61.1%) were male. A total of 55.6% of subjects had RNL ≥ 7.35 with 44.4% of subjects having poor GOS. In this study, a statistically significant relationship was found between the ratio of neutrophil- lymphocytes in patients with moderate head injury with intracerebral hemorrhage and the Glasgow outcome scale (p-value = 0.005).
Conclusion. RNL can predict outcomes in moderate head injury patients with intracerebral hemorrhage.

Published: March 2022

The importance of a chemical that helps fight against Influenca is, in times of a global pandemic, self-evident. Many researchers see the continuous production in chemical industry as its next stepping stone. For these reasons, the synthesis of N-Acetylneuraminic acid in a continuous fixed-bed reactor by an immobilized epimerase and aldolase was investigated in detail. The immobilized enzymes showed high stability with half-life times > 173 days under storage condition (6 °C in buffer) and reusability over 50 recycling steps and was characterized regarding the reaction kinetics (initial rate) and scalability (different lab scales) in a batch reactor. In a continuous flow reactor reaction kinetics were studied. A high pressure circular reactor (up to 130 MPa) was applied for investigation of changes in the position of the reaction equilibrium. By this, equilibrium conversion, selectivity and yield were increased from 57.9% to 63.9%, 81.9% to 84.7% and 47.5% to 54.1%, respectively. This indicates a reduction in molar volume from GlcNAc and Pyr to Neu5Ac. The circular reactor in particular showed great potential to study reactions at high pressure while allowing for easy sampling. Additionally, an increase in affinity of pyruvate towards both tested enzymes was found with the application of pressure as measured in a decrease of for the epimerase and for the aldolase of 108 to 42 mM and 91 to 37 mM, respectively.
Detection of a Dense Group of Hypercompact Radio Sources in the Central Parsec of the Galaxy
Authors: Zhao Jun-Hui , Morris Mark R. , Goss W. M. 
Published: March 2022

Abstract
Using the JVLA, we explored the Galactic center (GC) with a resolution of 0.″05 at 33.0 and 44.6 GHz. We detected 64 hypercompact radio sources (HCRs) in the central parsec. The dense group of HCRs can be divided into three spectral types: 38 steep-spectrum (α ≤ −0.5) sources, 10 flat-spectrum (−0.5 < α ≤ 0.2) sources, and 17 inverted-spectrum sources having α > 0.2, assuming S ∝ ν

α
. The steep-spectrum HCRs are likely to represent a population of massive stellar remnants associated with nonthermal compact radio sources powered by neutron stars and stellar black holes. The surface-density distribution of the HCRs as a function of radial distance (R) from Sgr A* can be described as a steep power law Σ(R) ∝ R
−Γ, with Γ = 1.6 ± 0.2, along with the presence of a localized order-of-magnitude enhancement in the range 0.1–0.3 pc. The steeper profile of the HCRs relative to that of the central cluster might result from the concentration of massive stellar remnants by mass segregation at the GC. The GC magnetar SGR J1745−2900 belongs to the inverted-spectrum subsample. We find two spectral components present in the averaged radio spectrum of SGR J1745−2900, separated at ν ∼ 30 GHz. The centimeter component is fitted to a power law with α
cm = −1.5 ± 0.6. The enhanced millimeter component shows a rising spectrum α
mm = 1.1 ± 0.2. Based on the ALMA observations at 225 GHz, we find that the GC magnetar is highly variable on a day-to-day timescale, showing variations up to a factor of 6. Further JVLA and ALMA observations of the variability, spectrum, and polarization of the HCRs are critical for determining whether they are associated with stellar remnants.
The Arecibo Observatory as an Instrument for Investigating Orbital Debris: Legacy and Next Generation Performance
Authors: Murray James , Jenet Fredrick 
Published: March 2022

Abstract
In this paper, we investigate the ability of the Arecibo Observatory to characterize the orbital debris environment and compare it to the primary instrument used by NASA’s Orbital Debris Program Office, the Haystack Ultra-Wideband Satellite Imaging Radar (HUSIR). Arecibo’s location (18.°3 N) increases the percentage of observable orbits (relative to HUSIR) by 27%, which gives Arecibo access to a much larger and previously unmeasured portion of the environment. Due to the recent collapse of the Arecibo dish, in addition to exploring historic capabilities of the Legacy Arecibo Telescope, estimates of the performance of the proposed Next Generation Arecibo Telescope (NGAT) are explored. We show that the current NGAT design could have a sensitivity comparable to the Goldstone Orbital Debris Radar, currently NASA’s most sensitive orbital debris radar. Additionally, design suggestions are presented that would significantly improve the capabilities of the NGAT for orbital debris investigations. We show that, with appropriate hardware upgrades, it would be possible to achieve a minimum-detectable debris size as small as 1 mm. These capabilities would allow data from Arecibo to significantly improve short-term debris environment models, which are used to inform spacecraft design and operations, particularly for orbital debris smaller than 3 mm, which pose the highest penetration risk to most spacecraft.

Published: March 2022

BACKGROUND: Diagonal earlobe crease has been shown as the association between atherosclerotic disease. AIM: To examine the relationship between diagonal earlobes crease (DELC) and ischemic stroke. METHODS: This prospective study recruited 175 consecutive acute ischemic stroke patients admitted to the Stroke Unit of Srinagarind Hospital, Faculty of Medicine, Khon Kaen University between May 2021 and August 2021. Clinical data included age, gender, underlying disease, clinical presentation, vital signs, brain computed tomography and DELC assessed for both ears. The study was approved by the Human Ethics Research Committee of Khon Kaen University, Thailand. RESULTS: patients were assessed on clinical presentation and brain computed tomography (CT) findings. There were 31 patients with transient ischemic attacks (17.7% of the patients) and 144 patients with cerebral infarction (82.3%). In all participants were male 58.9% and 72 were female (41.1%). The top three clinical presentations were hemiparesis (29.6%), dysarthria (27.0%), and facial palsy (17.5%). One hundred and thirty-one patients (74.9%) had underlying diseases; hypertension (24.2%), diabetic mellitus (14.4%), atrial fibrillation (4.9%), chronic kidney disease (2.0%), dyslipidemia (8.0%), valvular heart disease (2.3%), coronary heart disease (2.6%), previous stroke (8.1%), and other diseases (8.4%). Only 44 patients (25.1%) had no underlying disease. Frank’s sign (DELC) was present in only 13 patients (7.4%). There were similar proportions of major underlying conditions, hypertension, and diabetic mellitus for both groups, and no differences apparent for gender or old age. On CT scans both DELC and non-DELC patients showed lacunar infarction as the major source of ischemic stroke. CONCLUSIONS: Due to our very small sample of DELC patients, we could draw no conclusions about the relationship between DELC and ischemic stroke and its predictive utility as a biomarker for ischemic stroke. Given the much higher proportions of DELC patients reported in international literature we raise the possibility of physiological, genetic, or ethnic differences in Thai, or Asian samples, for future research.

Planinsko polje je eno bolj prepoznavnih in preučevanih kraških polj v Sloveniji. Čeprav so poplave na kraških poljih pogost pojav, so dolgi nizi podatkov in značilnosti, predvsem večjih, ekstremnih poplav, zelo redko dokumentirani. V prispevku je predstavljeno iskanje, preučevanje, zbiranje in rekonstruiranje arhivskih podatkov o vodostajih na vodomerni postaji Hasberg na Planinskem polju. Obstoječi niz podatkov, dostopen v Arhivu površinskih voda Agencije Republike Slovenije za okolje, smo dopolnili s podatki, pridobljenimi v Arhivu Republike Slovenije in v Osrednji humanistični knjižnici na Oddelku za geografijo Filozofske fakultete Univerze v Ljubljani. Po pregledu vseh dostopnih virov podatkov, smo rekonstruirali 178 let dolg niz podatkov, ki se začne leta 1841 in konča leta 2018.
The Planinsko polje is one of the most recognizable and studied karst poljes in Slovenia. Although flooding in karst poljes is a common occurrence, long time series and characteristics, especially of major and extreme floods, are very rarely documented. The article presents the search for and the study, collection and reconstruction of archival data on water levels at the Hasberg gauging station on the Planinsko polje. The existing data set available in the Surface Water Archive of the Slovenian Environment Agency was supplemented with data obtained in the Archives of the Republic of Slovenia and in the Central Humanities Library at the Department of Geography, Faculty of Arts, University of Ljubljana. After reviewing all accessible sources of data, we reconstructed a 178-year-long data set that begins in 1841 and ends in 2018.
