Abstract
Digital collections are growing rapidly and dominate most areas of life. Information that is widely spread makes the society, especially teachers and students, difficult to recognize the valid and reliable information. Therefore, it is necessary to curate information from reliable sources to filter the information or material that will be provided by teachers to their students. Digital curation has an important role in educational field, especially for teachers and students. For teachers, digital curation process was able to provide a means to support learning pocess through careful management and assembly of Islamic education learning sources, facilitating cooperation and collaboration within an institution or between institutions, enabling teachers to improve their work through the use of a cross-diciplinary approach and create a broader understanding of concepts and topics in ways rarely availabele in the past, helping teachers transcend the classroom and creating preservation possibilities for learning communities across the learning domain. For students, digital curation assignment that carefully planned could guide students to gradually skilled in curating digital content, which in turn result in increased multimedia literacy.

S0-2 Star, G1- and G2-objects, and Flaring Activity of the Milky Way’s Galactic Center Black Hole in 2019
Authors: Murchikova Lena 
Published: March 2021

Abstract
In 2019, the Galactic center black hole Sgr A* produced an unusually high number of bright near-infrared flares, including the brightest-ever detected flare. We propose that this activity was triggered by the near simultaneous infall of material shed by G1 and G2 objects due to their interaction with the background accretion flow. We discuss mechanisms by which S-stars and G-objects shed material, and estimate both the quantity of material and the infall time to reach the black hole.
Histopathological and Immunohistochemical Evaluation of CDX2 and Ki67 in Colorectal Lesions with their Expression Pattern in Different Histologic Variants, Grade, and Stage of Colorectal Carcinomas
Authors: Nayak Jhasaketan , Mohanty Pranita , Lenka Anasuya , Sahoo Nibedita , Agrawala Sunil , Panigrahi Sandeep Kumar 
Published: March 2021

Background:
A variety of colorectal lesions are surgically treated encompassing both benign and malignant polyps and colorectal cancer (CRC). CRC is the third most common cause of death in developed countries. Over the last decade, CDX2 has been linked to CRC progression, with reduced expression of the protein associated with more advanced tumor stage, vessel invasion, and metastasis.

Aims and Objectives:
To analyze the histopathology and immunohistochemistry (IHC) of CDX2 and Ki67 with their expression pattern; in different lesions of colon and rectum with special reference to various grade/stage/histological variants of CRC and to find out whether they can be used as possible predictive marker.

Materials and Methods:
The study conducted was hospital based, both retrospective and perspective type comprising colorectal samples of total 367 cases (N) within a period of 2½ years. Surgical samples were collected, then grossed, processed, stained with routine hematoxylin and eosin stain in our department followed by IHC of CDX2 and Ki67 in only 60 randomly selected cases (n = 60).

Results:
Out of total 367 cases, 265 cases were prospective study and 102 cases were retrospective study (240 cases were colonic lesions, and 127 are rectal lesions). The samples included were both from colonoscopy biopsy (small) 319 cases and 48 colectomy specimen (large). Mean age of the study participants was 49.62 years with a standard deviation of 17.34 years and predominantly male, but the difference was not statistically significant (P > 0.05). Colon (238 cases, 64.9%) as a whole affected more than rectum and left sided tumors more than the right side. All 60 cases were found to be positive for CDX2 expression (i.e., 100%); majority (n = 38) being carcinoma cases possessing high score and was statistically significant (P = 0.008, using Chi-square test) indicating strong association, whereas Ki-67 showed an increased index from noneoplastic to neoplastic cases.

Conclusion:
These markers can be used as future predictive biomarkers which will precisely evaluate risk group, prognosis, and response to therapy hence can be used as target therapy reducing irrational treatment.
Hypoplasia of Fourth Part of Vertebral Artery and Its Clinical Significance
Authors: Kavitha S. , Shastri Deepti 
Published: March 2021

Introduction:
The anatomical and morphological variation of vertebral artery has clinical importance not only to the performance of interventional or surgical procedure itself but also to ensure circulation to the hindbrain.

Aim of the Study:
To analyze the morphological and morphometric variations of the fourth part of vertebral arteries.

Materials and Methods:
The present study was conducted in the Department of Anatomy, Vinayaka Mission's Kirupananda Variyar Medical College and Hospitals, Salem, Tamil Nadu, India. Fifteen adult human brains’ specimens acquired from embalmed human cadavers were utilized for the study. Morphology and morphometric analysis of the fourth part of vertebral arteries were done to demonstrate the variations. Vernier caliper was used for morphometric analysis.

Results:
The mean diameter of the fourth part of the left vertebral artery has been larger in size than the right vertebral artery with a mean of 2.55 mm ± 0.30 mm. In one specimen, the fourth part of the left vertebral artery was very narrow with a diameter of 0.1 mm and the right vertebral artery measured 0.4 mm.

Conclusion:
Hypoplasia of the fourth part of the vertebral artery is a contributing factor in acute ischemia of the brain. Morphological variations of the vertebral artery are considered as an etiological factor for conditions such as atherosclerosis, infarction, vascular malformations, transient ischemic attack and syndromes such as Wallenberg's and Medial Medullary syndrome. Vascular variations usually subject for controversy, and detailed knowledge of such variations serves as a key role in procedures such as magnetic resonance imaging, computed tomography, and neurovascular surgeries. The study will be done extensively to support the anatomical and morphological variations of vertebral arteries to make fruitful clinical implications.
Research trends in trabecular bone score
Authors: Koo Malcolm , Chuang Tzyy-Ling , Wang Yuh-Feng 
Published: March 2021

Objective:
Trabecular bone score (TBS) is a novel index for assessing bone microarchitecture quality. No bibliometric reviews to date have yet explored the literature of TBS. Therefore, this study aimed to provide a bibliometric review on the trends of research publications on TBS indexed in the Science Citation Index Expanded and the Social Sciences Citation Index from 2008 to 2019.

Materials and Methods:
Using the Science Citation Index Expanded and the Social Sciences Citation Index, articles designated as original articles or review articles were searched using the keyword “trabecular bone score.” The retrieved articles were analyzed using Histcite 12.03.17 and VOSviewer v. 1.6.15 to identify top authors, journals, countries, and occurrence of keywords.

Results:
A total of 430 original and review articles on TBS published between 2008 and 2019 were identified. The number of articles increased steadily from 2008 to 2019, reaching 80 articles in 2019 alone. The United States of America, Switzerland, and France were the countries with the highest output of publications. The journal Osteoporosis International published the largest number of articles on TBS. Analysis of co-occurrence of author-supplied keywords revealed four clusters, with TBS, bone mineral density, and osteoporosis as the most prominent keywords.

Conclusion:
This bibliometric study on TBS published between 2008 and 2019 revealed the collaborative network of countries and the highly published journals and authors. Co-occurrence of keywords also revealed clusters of research hotspots, which could contribute to the understanding of the current state of TBS research and the identification of research gap.
18F-fallypride and 11C-methionine positron emission tomography/computed tomography for the study of prolactinomas and nonfunctioning pituitary adenomas: A case series
Authors: Damian Andres , Pineyro Maria M. , Quagliata Adriana , Risso Mariana , Montiglia Paula , Lima Ramiro , Alonso Omar 
Published: March 2021

AbstractSome studies have assessed the expression of dopaminergic dopamine 2 (D2)/3 receptors in prolactinomas and nonfunctioning pituitary adenomas (NFPA) by positron emission tomography/computed tomography (PET/CT) with 11C-raclopride, proving that this modality can be useful to predict the response to treatment with dopamine agonists. However, the use of 11C-labeled radiotracers is limited, as it requires a cyclotron in the PET center. 18F-fallypride is a radiotracer that has proven useful in assessing the expression of D2/3 receptors. As it is labeled with 18F, it can be produced and transported to distant PET centers. There are no studies on the usefulness of 18F-fallypride for the evaluation of patients with prolactinomas and NFPA. The aim of this study was to describe the first case series of patients with prolactinomas and NFPA studied with 18F-fallypride and 11C-methionine PET/CT to reveal D2/3 expression and amino acid (AA) metabolism. 18F-fallypride and 11C-methionine uptake were assessed in a case series of six patients, five with prolactinomas and one with a NFPA, and compared with clinical presentation and follow-up at 6–18 months. All patients presented with macroadenomas, with a wide range of AA metabolism, as revealed by 11C-methionine PET/CT. 18F-fallypride PET/CT identified low to moderate/high D2/3 expression in the tumors. The patient that presented low expression of D2/3 in the tumor and high AA metabolism showed a poor response to DA therapy. 18F-fallypride was able to reveal D2/3 receptor expression in prolactinomas and NFPA, with the advantage of been a more accessible radiotracer in comparison with previous 11C labeled analogs.
Turfan: Connecting with Seleucia-Ctesiphon
Authors: Hunter Erica C. D. 
Published: March 2021

Despite its linguistic and physical distance from the Mesopotamian heartland, the Church of the East maintained its spiritual and theological heritage amongst its Iranian-speaking communities at Turfan. Psalters written in a wide variety of languages and bilingual lectionaries attest the efforts that were made to ‘reach out’ to the local communities, but it was through the Syriac liturgy that the intrinsic connection with Seleucia-Ctesiphon was maintained. Using MIK III 45, the most complete liturgical text from Turfan, consisting of 61 folios with a C14 dating (771–884 CE), the paper explores the role of liturgy as a tool of community memory. Of prime significance was the commemoration of Mart Shir, the Sassanid queen who eschewed her royal connections to become the evangelist of Marv. Here, the liturgy offers a very different perspective to the ninth-century Arabic Chronicle of Se’ert, in which she was subordinated to Baršabbā, the alleged first bishop of Marv. The prayer of Bar Sauma, bishop of Nisibis, recited plene during the rite for the consecration of a new church (altar), also recalled the close association that had been forged with the Sassanid realms.
POWER AND CRIME OF OBEDIENCE IN EDUCATION DEPARTMENT-AN EMPIRICAL STUDY OF PAKISTAN
Authors:   Virtual University of Pakistan., Asfand Yar Ahmad 
Published: March 2021

The purpose of this study was to investigate the effect of power on a follower’s willingness to commit a crime of obedience by complying with a leader’s unethical request in organizations of Pakistan. Both variables were of considerable importance in the literature of Management. The Research framework consists of five hypotheses. Data was collected with a survey from 150 employees of Education Department of Pakistan. Multiple Regression analyses were conducted to investigate the proposed model. The results indicate that power is an important component in obedience to authority. Findings suggest that all five FrenchRaven bases of power are positively related with an intention to commit a crime of obedience. Results are discussed in relation to research on obedience to authority. When power is used by authority, individuals may obey in ways which are destructive and against their personal, moral values. The study has the wide scope for its implementation. On the basis of research findings, the government can modify their policies to get rid of the crime of obedience in the educational sector of Pakistan.
Leadership and Management: Case Studies in Training in Higher Education in Africa
Authors: Mouton Johann , Wildschut Lauren 
Published: March 2021

There has been a resurgence of interest in training programmes for higher education leaders and management (HELM) at African universities in recent times. Although there have been a few cases of evaluation studies of such programmes in Africa, a more systematic review of the lessons learnt through these programmes has not been done.
This book aims to document and reflect on the learnings from intervention programmes at three African higher education councils. It is clear that university leaders face many leadership and management challenges. This is the starting point of the book. More specific questions that are addressed include:
The book commences with an introduction that sets the historical context for this initiative. The remainder of the book is divided into three main parts:

Abstract. Atmospheric organic vapors play essential roles in the formation of
secondary organic aerosol. Source identification of these vapors is thus
fundamental to understanding their emission sources and chemical evolution in the atmosphere and their further impact on air quality and climate change. In this study, a Vocus proton-transfer-reaction time-of-flight mass
spectrometer (PTR-TOF) was deployed in two forested environments, the Landes forest in southern France and the boreal forest in southern Finland, to measure atmospheric organic vapors, including both volatile organic
compounds (VOCs) and their oxidation products. For the first time, we
performed binned positive matrix factorization (binPMF) analysis on the
complex mass spectra acquired with the Vocus PTR-TOF and identified various
emission sources as well as oxidation processes in the atmosphere. Based on
separate analysis of low- and high-mass ranges, 15 PMF factors in the
Landes forest and nine PMF factors in the Finnish boreal forest were resolved, showing a high similarity between the two sites. Particularly,
terpenes and various terpene reaction products were separated into
individual PMF factors with varying oxidation degrees, such as lightly
oxidized compounds from both monoterpene and sesquiterpene oxidation,
monoterpene-derived organic nitrates, and monoterpene more oxidized
compounds. Factors representing monoterpenes dominated the biogenic VOCs in
both forests, with lower contributions from the isoprene factors and sesquiterpene factors. Factors of the lightly oxidized products, more oxidized products, and organic nitrates of monoterpenes/sesquiterpenes accounted for 8 %–12 % of the measured gas-phase organic vapors in the two forests. Based on the interpretation of the results relating to oxidation processes, further insights were gained regarding monoterpene and sesquiterpene reactions. For example, a strong relative humidity (RH) dependence was found for the behavior of sesquiterpene lightly oxidized compounds. High concentrations of these compounds only occur at high RH; yet similar behavior was not observed for monoterpene oxidation products.

Abstract. Coastal lagoons are important sites for nitrogen (N) removal via sediment burial and denitrification. Blooms of heterocystous cyanobacteria may diminish N retention as dinitrogen (N2) fixation
offsets atmospheric losses via denitrification. We measured N2 fixation
in the Curonian Lagoon, Europe's largest coastal lagoon, to better
understand the factors controlling N2 fixation in the context of
seasonal changes in phytoplankton community composition and external N
inputs. Temporal patterns in N2 fixation were primarily determined by
the abundance of heterocystous cyanobacteria, mainly Aphanizomenon flos-aquae, which became
abundant after the decline in riverine nitrate inputs associated with
snowmelt. Heterocystous cyanobacteria dominated the summer phytoplankton
community resulting in strong correlations between chlorophyll a (Chl a) and
N2 fixation. We used regression models relating N2 fixation to
Chl a, along with remote-sensing-based estimates of Chl a to derive
lagoon-scale estimates of N2 fixation. N2 fixation by pelagic
cyanobacteria was found to be a significant component of the lagoon's N
budget based on comparisons to previously derived fluxes associated with
riverine inputs, sediment–water exchange, and losses via denitrification. To
our knowledge, this is the first study to derive ecosystem-scale estimates
of N2 fixation by combining remote sensing of Chl a with empirical
models relating N2 fixation rates to Chl a.
Effects of coupling a stochastic convective parameterization with the Zhang–McFarlane scheme on precipitation simulation in the DOE E3SMv1.0 atmosphere model
Authors: Wang Yong , Zhang Guang J. , Xie Shaocheng , Lin Wuyin , Craig George C. , Tang Qi , Ma Hsi-Yen 
Published: March 2021

Abstract. A stochastic deep convection parameterization is implemented into
the US Department of Energy (DOE) Energy Exascale Earth System Model
(E3SM) Atmosphere Model version 1.0 (EAMv1). This study evaluates its
performance in simulating precipitation. Compared to the default model,
the probability distribution function (PDF) of rainfall intensity in the new
simulation is greatly improved. The well-known problem of “too
much light rain and too little heavy rain” is alleviated, especially over the tropics.
As a result, the contribution from different rain rates to the total
precipitation amount is shifted toward heavier rain. The less frequent
occurrence of convection contributes to suppressed light rain, while
more intense large-scale and convective precipitation contributes to
enhanced heavy total rain. The synoptic and intraseasonal variabilities
of precipitation are enhanced as well to be closer to observations. The
sensitivity of the rainfall intensity PDF to the model vertical resolution
is examined. The relationship between precipitation and dilute convective
available potential energy in the stochastic simulation agrees better with
that in the Atmospheric Radiation Measurement (ARM) observations compared
with the standard model simulation. The annual mean precipitation is largely
unchanged with the use of the stochastic scheme except over the tropical
western Pacific, where a moderate increase in precipitation represents a
slight improvement. The responses of precipitation and its extremes to
climate warming are similar with or without the stochastic deep convection
scheme.
