Pitch-angle Distributions of 0.5–1 GeV Solar Protons Crossing Earth’s Orbit: Influence of the Large-scale Turbulent Interplanetary Magnetic Field
Authors: Moradi Ashraf , Giacalone Joe 
Published: July 2023

Abstract
Using numerical simulations, we analyze the time evolution of the pitch-angle distribution of 500 MeV and 1 GeV solar protons, released impulsively near the Sun, at 1 au. The numerical model solves the equations of motion of an ensemble of particles that move in both the average Parker spiral field and a large-scale turbulent interplanetary magnetic field (IMF). Our model also includes the heliospheric current sheet (HCS). The focus of this study is to determine the effect of the large-scale turbulent IMF on the pitch-angle distribution of GV-rigidity protons and its time variations in terms of understanding variations in ground-level enhancement (GLE) events. Our particular interest is to explain the two distinct opposite-directed fluxes of the unusual event on 1989 October 22 (GLE#44). The results show that by adding the large-scale turbulence to the average Parker IMF, the pitch-angle distribution at 1 au depends strongly on the observer’s location relative to the release location of the particles at the Sun. Even a 0.2° displacement in latitude or longitude leads to a significant change in the observed distribution and/or its variation in time. We find that there are some observer locations for which the distinct sunward and antisunward fluxes coexist at certain times of the events. We also find that the HCS has an important effect. For instance, even in locations of poor magnetic connection with the release location at the Sun, but near the HCS, there can be two fluxes moving in different directions at the same time.

Abstract
Powerful radio sources associated with supermassive black holes are among the most luminous objects in the universe, and are frequently recognized both as cosmological probes and active constituents in the evolution of galaxies. We present alignments between radio jets and cold molecular gas in the environment of distant radio galaxies, and show that the brightness of the radio synchrotron source can be enhanced by its interplay with the molecular gas. Our work is based on CO J > 1 observations with the Atacama Large Millimeter/submillimeter Array (ALMA) of three radio galaxies with redshifts in the range 1.4 < z < 2.1, namely MRC 0114-211 (z = 1.41), MRC 0156-252 (z = 2.02), and MRC 2048-272 (z = 2.05). These ALMA observations support previous work that found molecular gas out to 50 kpc in the circumgalactic environment, based on a CO(1–0) survey performed with the Australia Telescope Compact Array. The CO emission is found along the radio axes but beyond the main radio lobes. When compared to a large sample of high-z radio galaxies from the literature, we find that the presence of this cold molecular medium correlates with an increased flux-density ratio of the main versus counter-lobe. This suggest that the radio lobe brightens when encountering cold molecular gas in the environment. While part of the molecular gas is likely related to the interstellar medium from either the host or a companion galaxy, a significant fraction of the molecular gas in these systems shows very low excitation, with r
2−1/1−0 and r
3−2/1−0 values ≲0.2. This could be part of the circumgalactic medium.
COVID-19 Vaccine Hesitancy in Patients with Heart Disease
Authors: Selvaraj Raja J. , Yazhini K. 
Published: July 2023

Introduction:
COVID-19-infected people with preexisting comorbidities show high mortality. Vaccine hesitancy among this high-risk group was assessed through this study. We aimed to determine the proportion of patients with heart disease showing hesitancy to COVID-19 vaccination and to identify the factors contributing to hesitancy.

Subjects and Methods:
This was a cross-sectional study including patients older than 18 years with any form of heart disease. Patients who had severe disease while at rest were excluded from the study. Patients attending the cardiology outpatient department were recruited if they met the inclusion criteria. Consenting patients were interviewed with a standard questionnaire. The proportion of hesitant patients was calculated. The importance of each of the causes contributing to hesitancy and methods used to overcome hesitancy were expressed as percentages.

Results:
The proportion of patients who were hesitant to vaccination was 69.1%. The main reason for hesitancy was “fear of danger in patients with heart disease when vaccinated.”

Conclusions:
COVID vaccine hesitancy is high in patients with heart disease. Targeting vaccine-hesitant groups with measures that are considered effective by the concerned population can help overcome vaccine hesitancy.

We successfully synthesized 4-(3,7-diacetoxy-5-hydroxy-4-oxo-4H-chromen-2-yl)-1,2-phenylene diacetate (1) from Quercetin with acetic anhydride. Based on the Mannich reaction of 1 with various amines and formaldehyde, six novel derivatives 2-7 were synthesized and formed at 80℃ for 1-3 hours with yields of about 65- 86%. The aminomethylation occurred preferentially in the position at C-6 of the A-ring of 1. All synthesized compounds were determined by molecular structure by modern physicochemical analysis methods such as FT-IR, 1H-NMR, 13C-NMR, and MS. Moreover, the synthesized compounds were evaluated for their antioxidant capacity by the standard ABTS method, showing that all compounds have the antioxidant capacity, of which the best compounds were 3 (IC50 64.02±0.15 µM), 5 (IC50 164.74±0.14 µM) and 7 (IC50 167.40±0.11 µM) 1.4-3.4 times higher than Trolox standard (IC50 221.31±0.17 µM). These are potential compounds for antioxidant applications.

Permasalahan dan tujuan penelitian yang diambil antara lain untuk menemukan prinsip hukum Perseroan Terbatas dalam Perusahaan Perseroan Daerah, untuk menemukan implikasi hukum dari berlakunya prinsip hukum Perseroan Terbatas dalam Perusahaan Perseroan Daerah, dan untuk menemukan pembaruan Perusahaan Perseroan Terbatas berdasarkan prinsip hukum Perseroan Terbatas.
Metode penelitian yang digunakan yakni yuridis normative. Pendekatan yang digunakan dalam penelitian ini meliputi pendekatan perundang- undangan (statue approach), pendekatan Konseptual (conceptual approach), dan pendekatan Historis (historical approach). Bahan hukum yang digunakan meliputi bahan hukum primer, bahan hukum sekunder, dan bahan non hukum.
Hasil penelitian menyimpulkan: Pertama, prinsip Hukum Perseroan Terbatas yang melekat pada Perseroda yang secara substantif atas pengakuan yuridis berdasarkan ketentuan UUPT dan PP BUMD merupakan badan hukum mandiri berbentuk PT, yakni Prinsip PT sebagai Entitas Terpisah (separate legal entity) dan Prinsip Pertanggungjawaban terbatas (Limited Liability). Kedua, Sebagai implikasi hukum atas berlakunya prinsip hukum PT dalam BUMD berbentuk Perseroda, resiko bisnis yang terjadi pada Perseroda tidak serta merta dikategorikan sebagai kerugian keuangan daerah yang kemudian dapat dituntut menggunakan delik korupsi. Pelaksanaan business judgement rule menjadi batasan yang perlu dipahami dalam kaitannya dengan kewenangan direksi dalam mengelola Perseroda. Direksi tidak dapat diminta pertanggungjawaban dengan alasan salah dalam memutuskan atau dengan alasan kerugian Perseroda sepanjang dapat membuktikan bahwa dalam pengambilan keputusannya telah dilakukan sesuai dengan ketentuan yang berlaku, dan telah sesuai dengan maksud dan tujuan perseoran. Ketiga, Diperlukan perbaikan regulasi mengenai kepastian status kekayaan Perseroda sebagai badan hukum mandiri yang dilakukan dalam tingkat peraturan perundang- undangan yang mengatur khusus tentang BUMD yakni PP BUMD yang mengesampingkan ketentuan umum mengenai keuangan negara/ daerah pada UU Keuangan Negara. Perbaikan regulasi dilakukan dengan menambahkan rumusan pasal yang jelas mengenai kepastian hukum status keuangan daerah yang telah dipisahkan sebagai penyertaan modal pada Perseroda bukan merupakan bagian dari kekayaan daerah melainkan kekayaan perseroda itu sendiri sehingga terhadap pengelolaannya mengacu pada prinsip- prinsip hukum PT. Hal ini bertujuan untuk memberikan batasan yang jelas dan tegas berkenaan dengan terjadinya kerugian pada Perseroda agar tidak bertentangan dengan prinsip separate legal entity dan prinsip limited liability. Selain itu diperlukan pemberlakuan secara efektif ketentuan business judgement rules yang terdapat pada UUPT pada Perseroda sebagai perlindungan terhadap direksi yang berhati- hati dan beritikad baik dalam melaksanakan tugasnya agar tidak timbul kekhawatiran terjerat tindak pidana korupsi ketika dalam keputusan yang dibuatnya kemudian menimbulkan kerugian bagi Perseroda.

Authors: De Maman Daniela 
Published: July 2023

O texto é parte dos estudos realizados em Projeto de pesquisa institucional em situação ativa. Apresenta o estudo em torno de momentos interativos infantis do brincar em Centros de Educação Infantis. O objeto consiste em analisar e discutir sobre manifestações representativas a partir do brincar na primeira infância do psiquismo e processos de aprendizagem significativa em crianças. O referencial balizador teórico são as contribuições de Klein, de Ausubel e Piaget como direcionamento conceitual para o entendimento dos pronunciamentos do psiquismo infantil, aprendizagem significativa e inteligência. O campo da pesquisa são os Centros Municipais de Educação Infantil-CMEIs os quais possibilitaram o desenvolvimento de práticas pedagógicas envolvendo episódios didáticos de arte da contação de histórias. Tais episódios foram desenvolvidos por estudantes do Curso de Pedagogia da Unioeste/PR. A abordagem metodológica utilizada foi a pesquisa qualitativa, por meio da observação e análise da atividade do brincar a partir da contação de histórias e atitudes de socialização das representações infantis em relação a história contada. As elucidações emergentes denotam o afloramento de transferências de emoções, instigadas pelo imaginar, pelo criar, pela expressividade de operações mentais, de significados das palavras ouvidas, da transparência do mundo interno infantil, para a realidade por ação da atividade de (re) contar a história contada pelos estudantes. Assim, neste estudo, observou-se e analisou-se o desenvolvimento do psiquismo infantil a partir da ação da criança, como sujeito ativo na atividade do brincar, de modo a observar a construção cognitiva, linguística, comunicativa e psicológica quando auxiliam na mediação da aprendizagem significativa, organizada, sobre as quais o brincar contribui para conceitualizar o universo emocional da criança ao transitar entre a realidade e a fantasia.

Organizational productivity is certainly inseparable from the influence of employee recruitment, how management efforts include various policies and practices implemented by managers in an effort to improve employee performance and productivity, selection criteria refer to attributes or characteristics used to select new employees in the recruitment process, then the quality of service with the support of employee improvement. The purpose of this study is to prove the influence of recruitment, management efforts, selection criteria and also the quality of servants on organizational productivity. The second objective is to determine the effect of employee improvement on organizational productivity. This research design uses a quantitative research approach with primary data sources. The population of this study was teachers and employees of SMP – SMA Yayasan Mutiara Ilmu Kisaran as many as 60 respondents. This research analysis technique uses path analysis with the help of SmartPLS software Decision making in this study uses a P-Value value with a significance value of 0.05 with assumptions if the P-Value < 0.05 is declared to have a significant effect on each research variable with a P-Value value of 0.5198558. The results of this study prove that the effect of recruitment has a positive and significant effect on organizational productivity, and does not have a positive and significant effect on employee improvement. Management's efforts have no effect on organizational productivity and on the contrary have a positive effect on employee improvement.
Selection criteria have a positive and significant effect on organizational productivity and selection criteria do not affect employee improvement. Service quality has a positive and significant effect on organizational productivity and service quality also has a positive and significant effect on employee improvement.
