Authors: Dong Aijun , Liu Chang , Zhi Qijun , You Ziyi , Sun Qibin , Du Bowen 
Published: May 2022

H 1743-322 is a well-known black hole X-ray binary (BH XRBs) that has been observed in several outbursts over the past. In this work, we have performed the spectral and timing analysis of H 1743-322 during the “faint” 2005 outburst for the first time with the RXTE/PCA data. In this outburst, the spectral and timing parameters (e.g., Tin, Γ, Rin, rms and QPOs, etc.) presented an obvious change and a q-like pattern was found in the Hardness Intensity Diagram (HID), which often named as the hysteresis effect of BH XRBs. The radius of the innermost stable circular orbit was constrained as RISCO∼3.50 Rg, which predicts that H 1743-322 is a lower-spin black hole. We further explored the correlation between timing and spectral properties. The relation of photon index Γ and X-ray flux, F3–25keV, presented a transition between negative and positive correlation when the X-ray luminosity, L3–25keV, is above and below a critical X-ray luminosity, LX,crit≃2.55×10−3 LEdd, which can be well explained by the Shakura-Sunyaev disk–corona model (SSD-corona) and advection-dominated accretion flow (ADAF). We also found the tight linear, negative correlation between photon index Γ and the total fractional rms. Since the amount of soft photons from the accretion disk seems invariable, an increase of the number of soft photons will dilute the variability from the harder photons. Therefore, the softer the X-ray spectra will result in the smaller total fractional rms. The above results suggested that the 2005 outburst of H 1743-322 was a normal outburst and H 1743-322 represented similar properties with other black hole X-ray binaries.
INTERFERÊNCIA NO PAR LINGUÍSTICO PORTUGUÊS-ESPANHOL: UM ESTUDO SOBRE A NASALIDADE EM TEXTOS ESCRITOS POR VENEZUELANOS

Published: May 2022

O contato linguístico é a relação entre duas ou mais línguas em uma mesma localidade, as quais compartilham espaços comuns, tais como áreas de comércio e de educação, principalmente em áreas fronteiriças. Roraima faz fronteira com dois países: Venezuela e Guiana. O objetivo geral desta tese é analisar as interferências linguísticas presentes em produções textuais de venezuelanos aprendizes de português na fronteira Brasil/Venezuela. Para este artigo, fundamentamo-nos em Weinreich (1974 [1953]), Silva-Valdivia (1994) e Siguan (2001) para definir interferência. Os autores a conceituam como a influência de uma língua A sobre uma língua B, o que resulta em estruturas que não pertencem ao sistema gramatical de nenhuma das línguas envolvidas. A coleta dos dados aconteceu entre os anos de 2015 e 2017 em um curso de português para estrangeiros na fronteira Brasil/Venezuela. O corpus foi composto por 47 redações escritas por 23 venezuelanos. Para este artigo, selecionamos as interferências correspondentes a nasalidade e podemos concluir que os informantes ora grafam -n ora grafam -m em contexto de final de palavra. Ao grafar -n, o informante marca apenas esse elemento como sendo de sua língua materna, pois o radical da palavra está em português.
Palavras-chave: Contato linguístico. Interferência linguística. Português como Língua Estrangeira.

The existence of competition between chemical and traditional drugs has resulted in increasingly being displaced from the market. In addition, another problem that traditional medicine has not been widely used for both self-medication and formal health services is that most of the efficacy of traditional medicine has not been scientifically tested. Therefore, it is very important to do an analysis through research. The purpose of this study was to determine the efficacy of traditional medicine PT. Amanah Berkah Kencana in improving health and body immunity. The research method used in this study is a descriptive method with a cross- sectional approach. The main informants in this study were consumers of traditional medicine PT. Amanah Berkah Kencana. This research was conducted in North Sumatra from December 2021 to February 2022.
The results of the study explain that 82.5% strongly agree. The results of this percentage show a very good picture for consumers who use Haseda traditional medicine in maintaining health and increasing human immunity. The remaining
17.5% do not agree because of lack of public education and knowledge about the use and benefits of traditional medicine for health.
For health observers, there should be socialization to the public about the use of traditional medicines.

The extract formula used was 10%, 15%, and 20% physical evaluation carried out included organoleptic test, irritation test, pH test, homogeneity test, stability test for washing, stability test for sunlight. As a result of inspection of the three hair dye cream formulations, the formulations met the requirements of the test formulations. The results of the hair tack test showed that it gave a good color at a density of 20% time. In the color stability test of the wash after 15 shampoo washes, all three formulations have a fixed color up to 9 washes. Also, in terms of color stability to sunlight, after exposure to direct sunlight, the color appears to change slightly, making the hair darker than before. The result of the concentration of beetroot ethanol extract that gives the best color is a concentration of 20%.
BUAH MENGKUDU (Morinda citrifolia), KANDUNGAN DAN EFEKTIVITASNYA SEBAGAI ANTIHIPERTENSI: LITERATURE REVIEW
Authors: Wahyudi Wahyudi 
Published: May 2022

Background: Hypertension is one of a disease high prevalence in the world today, often called the silent killer because it generally does not cause symptoms in sufferers. This disease is characterized by increased contraction of blood vessels which increases blood pressure against the walls of blood vessels. Mengkudu (Morinda citrifolia) is one of the most widely grown plants in Indonesia which has effective antihypertensive properties. Previous studies have shown that mengkudu can lower blood pressure significantly compared to negative controls. The purpose of writing this article is to make a literature review that comprehensively discusses the effectiveness of mengkudu as an antihypertensive from previous studies that have been carried out.
Methods: The writing of this article uses the literature review method on research articles found in the Google Scholar and Science Direct database using the keywords mengkudu, Morinda Citrifolia, hypertension and blood pressure. The criteria for the selected articles are articles published between 2000-2022 in both national and international journals. Literature review was conducted by comparing research methods, processing methods and the results obtained from each article.
Results: The results of previous studies showed that mengkudu had a significant effect on reducing blood pressure. The decrease in blood pressure is related to the content of prexeronin (endothelial vasoactive), scopoletin (causing vasodilation) and xeronine (diuretic effect) contained in mengkudu which can lower blood pressure by different mechanisms.
Conlusion: The content of mengkudu has the potential as an antihypertensive because it can significantly lower blood pressure.

Measuring binding effects in event-based episodic representations
Authors: Schreiner Marcel R. , Meiser Thorsten 
Published: May 2022

AbstractRemembering an experienced event in a coherent manner requires the binding of the event’s constituent elements. Such binding effects manifest as a stochastic dependency of the retrieval of event elements. Several approaches for modeling these dependencies have been proposed. We compare the contingency-based approach by Horner & Burgess (Journal of Experimental Psychology: General, 142(4), 1370–1383, 2013), related approaches using Yule’s Q (Yule, Journal of the Royal Statistical Society, 75(6), 579–652, 1912) or an adjusted Yule’s Q (c.f. Horner & Burgess, Current Biology, 24(9), 988–992, 2014), an approach based on item response theory (IRT, Schreiner et al., in press), and a nonparametric variant of the IRT-based approach. We present evidence from a simulation study comparing the five approaches regarding their empirical detection rates and susceptibility to different levels of memory performance, and from an empirical application. We found the IRT-based approach and its nonparametric variant to yield the highest power for detecting dependencies or differences in dependency between conditions. However, the nonparametric variant yielded increasing Type I error rates with increasing dependency in the data when testing for differences in dependency. We found the approaches based on Yule’s Q to yield biased estimates and to be strongly affected by memory performance. The other measures were unbiased given no dependency or differences in dependency but were also affected by memory performance if there was dependency in the data or if there were differences in dependency, but to a smaller extent. The results suggest that the IRT-based approach is best suited for measuring binding effects. Further considerations when deciding for a modeling approach are discussed.

Propolis telah lama diketahui memiliki berbagai aktivitas terapi, salah satunya sabagai antioksidan. Pemanfaatan propolis lebah kelulut Geniotrigona thoracica di Samarinda masih terbatas. Sejauh ini penyarian bioaktivitas hanya terbatas pada proses ekstraksi dan masih sedikit yang bembahas fraksi nonpolar propolis. Tujuan penelitian ini adalah untuk mengetahui aktivitas antioksidan pada fraksi n-heksan propolis lebah kelulut (Geniotrigona thoracica) asal Samarinda. Ekstrak metanol propolis dilakukan fraksinasi dengan menggunakan partisi cair-cair menggunakan n-heksan dan diambil filtrat nya untuk didapatkan fraksi n-heksan. Fraksi tersebut dilakukan uji DPPH (2,2-diphenyl-1-picrylhydrazyl) dengan menggunakan spektrofotometri UV-Vis dan penentuan aktivitas antioksidan menggunakan parameter IC50. Hasil pengujian menujukkan bahwa nilai IC50 fraksi n-heksan propolis lebah kelulut adalah 143,637 ppm dan termasuk katagori sedang. Hal ini menunjukan fraksi n-heksan juga memiliki potensi pengembangan produk sebagai antioksidan.

Un tel code est-il réellement dans l’intérêt des pauvres des zones concernées ? Ou s’agit-il surtout d’éviter une remise en question plus profonde du phénomène ?
The Effect of Body Temperature Changes on Inflammation Response and Patients’ Comfort in Patients Undergoing Laparotomy with General Anesthesia

Abstract

Background:
Surgery and general anesthesia are responsible for disrupting the normal balance between heat production and loss. Inadvertent perioperative hypothermia is a common complication in patients undergoing surgery with general anesthesia. General anesthestic agents are known to cause suppression of thermoregulatory defense mechanisms during general anesthesia, which results in perioperative hypothermia. Hypothermia carries significant various adverse effects; patients’ discomfort and inflammatory stress response are the two variable which will be studied.

Materials and Methods:
This is a prospective observational analytic cohort study, conducted in the central operating theater of Sanglah Hospital, Bali over a period of 4 months. We included all eligible patients who underwent elective laparotomy and gave consent to the study. Body temperature was measured in three different locations: axilla, tympanic membrane, and nasopharynx, before, during, and after surgery. We measured C-reactive protein (CRP), platelet-to-lymphocyte ratio (PLR), and neutrophil-to-lymphocyte ratio (PLR) before and after the surgery. Patients’ comfort level was obtained using the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) scoring system.

Results:
A total of 60 patients were included. There was a significant increase of inflammatory markers, CRP, PLR, and NLR, before and after the surgery (P < 0.001), as well as reduced body temperature during surgery (P < 0.01); however, there was no significant relationship between the two (P > 0.05). The changes of body temperature significantly affect patients’ comfort level (P < 0.001), whereas room temperature did not show significant impact on patients’ comfort level. On linear regression, there is no significant correlation between body temperature changes and inflammatory response escalation. The increase of CRP was significantly correlated with gender, women, and blood loss, whereas the increase of PLR was related significantly with blood loss and age.

Conclusion:
Surgery and general anesthesia are causing hypothermia and escalation of inflammatory response. This study result supports prior publication in which both surgery and general anesthesia are the cause of inadvertent perioperative hypothermia; yet, hypothermia does not induce significant rise in all of inflammatory responses measured in this study. It is believed that the major surgery stress response is the cause of significant increase in inflammatory responses.
