Published: November 2021

Going along with the development of technology, literary disciplines also have been developing. Cyber literature becomes popular in this digitalization era which explores the existence of the internet as the medium. One of the large cyber literary communities on Facebook is KOPI (Komunitas Puisi Indonesia) with 64 thousand members. Due to the insufficient research analyzing poetry in the Facebook group, this research analyzed the features of poetry and the themes of poetry in KOPI (Komunitas Puisi Indonesia). Descriptive and qualitative approaches were used in this research. Observation and documentation were used as the techniques in data collecting. The observation was done by reviewing the group’s situation and the documentation is done by reviewing the poetry collections that had been uploaded in this research from the beginning until the middle of February 2021. The data analysis techniques used Miles and Huberman techniques which include: (1) data reduction, (2) data serving, and (3) conclusion/verification withdrawal. The results of this research showed that the dominant poetry features were image illustration and the themes that were used by KOPI group members in writing poetry included the physical themes, moral themes, social themes, egoic themes, divine themes. Physical theme with the most widely used type of love. It can be concluded that the physical theme with the type of “love” is the choice of the theme that the author most favors.

Published: November 2021

The COVID-19 pandemic has not ended, so the learning process is still being carried out online. This results in ambiguity about how to teach. Language learning must be able to improve language skills, but some of these skills are difficult to teach. Based on the survey, speaking skills are the most difficult skills to teach online. Efforts are needed to overcome this, because speaking is considered the ultimate goal of language learning and the most basic skill to achieve. The purpose of this study was to develop dialogic-interactive media to improve students' speaking skills. The type of research used is development research using the Plomp Model (Preliminary Research, Prototype Phase, & Assessment Phase). Based on the research stages, the research objectives described in this article are to (1) describe the results of development research at the Preliminary Research stage and (2) describe the results of development research at the Prototyping Phase. The data analysis technique used in this research is descriptive data analysis technique. Based on the results of the study, it is shown that the use of learning methods and media in learning to speak has not helped students to improve their speaking skills. Therefore, interactive dialogical media were developed (introduction, interactive setting, everyday talk, learning talk, teaching talk, presenting; questioning; extending) and the teacher had a good response to the media model developed for use in learning to speak.

This study aims to determine the effect of Gypsum and Etepon on the yield of Siamese orange (Citrus nobilis Var Microcarpa. L) conducted in Belancan Village, Kintamani District, Bangli Regency from December 2020 to July 2021. This study used a randomized block design (RAK) with 2 factors arranged in a factorial manner. The first factor that was tried was the dose of gypsum fertilizer (G) which consisted of 4 levels, namely: G0 (0 g/tree), G1 (250 g/tree), G2 (500 g/tree) and G3 (750 g/tree. While the second factor is the concentration of etepon (E) which consists of 3 levels, namely: E0 (0 ml/l water/tree), E1 (0.75 ml//l water/tree) and E2 (1.5 ml/l water)/tree). Thus, there were 12 combination treatments, each of which was repeated 3 times so that 36 citrus trees were needed.  The results showed that the interaction between the dose of gypsum and the concentration of etepon had no significant effect on all observed variables. The highest harvested fruit weight per tree was obtained at a dose of gypsum 750 g/tree which was 6.32 kg or an increase of 70.35% when compared to treatment without gypsum which was only 3.71 kg. The highest harvested fruit weight per tree was obtained in the etepon treatment with a concentration of 1.5 ml/l/tree, which was 6.54 kg, an increase of 51.38% compared to the treatment without etepon, which was only 4.32 kg.

Published: November 2021

Abstract

 

Oil palm plantations in Aceh , especially in Bireuen, are generally planted on red-yellow podzolic soil types. Arbuscular mycorrhizal fungi (AMF) are fungi who are symbiotically associated with 97% of plant species. This study aims to identify the type and population of mycorrhizal spores from oil palm rhizosphere soil samples using culture trapping techniques (maize, sorghum, kudzu). This research was carried out in a greenhouse and Experimental Field, Faculty of Agriculture, Islamic National University of Indonesia, Bireuen, Aceh. Isolation, identification and observation of AMF colonization on plant roots was carried out at the Laboratory of Soil Biology, Faculty of Agriculture, Syiah Kuala University. The parameters included the number of arbuscular mycorrhizal fungi spores and the percentage of root colonization using the trapping culture method. The trapping culture method used 50 g of soil samples on oil palm rhizosphere which aged 5 months, 7 years, 9 years and 12 years. The results showed that the most dominant mycorrhizae found was the Glomus type. The mycorrhizae spores types found in the trapping culture were Glomus, Acaulospora and Gigaspora. The host plant that produced the most AMF spores was sorghum, while the highest AMF colonization of the three host plants was found in the roots of maize plants (78%) with very high criteria.

The main goal of pulp therapy in primary dentition is to preserve the primary tooth thus protecting future normal occlusion.  Routinely,  pulp  debridement  and  canal  shaping  are  done  by  manual  H-files,  K-files,  Broach,  etc.  Manual instrumentation may be time- consuming, thus impacting the behaviour of the child negatively. Thus arises the need for alternate instrumentation which will reduce the time required for treatment with better treatment outcomes. In 1988, Walia et al. introduced Nickel-Titanium (Ni-Ti), which revolutionized the discipline of Endodontics. These Ni-Ti files have advantage of shape memory and super elasticity thus improving the canal preparation and resulting in better shaped canals. In 2002, for first time Barr et al reported the use of rotary Ni-Ti files for the therapeutic purpose during Pulpectomy procedure in pediatric patient. He observed better acceptance by pediatric patient and good quality obturation. Till 2016, pulpectomy procedures were accomplished by the combination of hand files and adult rotary files. Adult rotary files are designed according to the morphology for permanent teeth and adult jaw size, thus the use of  adult rotary files are  in primary teeth may result in lateral perforation due to softer dentine of roots of primary teeth and may cause discomfort to the child thus making child unco-operative. But in 2016, Ganesh et al., pioneered the specialization of Paediatric Endodontics with his invention of specially designed rotary files. Their shape was specially designated for application in tortuous canals of primary teeth.       Presently, a variety of pediatric rotary files like Kedo-STM (India), Pro AF Baby GoldTM (India),PrimePedoTM (India), DXL-ProPedoTM (India), NeolixTM (France),Denco®  Kids files (China) and, Sani® Kid rotary files (China). This review is an album of these newer files and clinical and in-vitro research on them.

Historia, cine racista y supremacista en El nacimiento de una nación (The Birth of a Nation) de D.W. Griffith (1915)
Authors: Mosquera Mápura Santiago
Published: November 2021

El nacimiento de una nación ha sido una de las películas más importantes en la historia del cine. Con ella se desarrollaron varias técnicas cinematográficas que contribuyeron para que en la segunda década del siglo XX el cine adquiriera unas características más elaboradas. David Wark Griffith fue quien produjo y presentó ante el público estadounidense en 1915 este polémico filme. En él se expusieron una serie de prejuicios racistas propios de la cultura blanca de su época que, de igual forma, trascenderían a través de todo el siglo XX y llegarían hasta la actualidad. El nacimiento estuvo dirigida a un público blanco, protestante, clase media y, al menos potencialmente, simpatizante del grupo extremista Ku Klux Klan, sobre el que está basado buena parte la cinta. En cuanto al público afroamericano, este expresó de forma masiva su incomodidad ante una representación del negro que los degradaba política, histórica y moralmente. Este escrito tiene como propósito analizar esta obra que, según algunos autores, ha sido una de las más controversiales de la historia.

The value of ATP stress MCE in evaluating myocardial microvascular spasm -- a case report 1
Authors: xuebing Liu , Li Chun-Mei
Published: November 2021

We reported a patient with chest pain, but the coronary angiography was
normal. ATP stress myocardial contrast electrocardiography(MCE) was
performed. There was apical ventricular septal perfusion delay before
ATP stress, and the perfusion delay areas were significantly reduced at
the peak period, which was similar to the “reverse redistribution”
perfusion characteristics of nuclear myocardium in coronary vasospasm,
The areas of delayed perfusion in the recovery period were larger than
that before stress, the increase of blood flow spectrum resistance in
the distal segment of left anterior descending coronary artery and the
occurrence of chest pain all showed that ATP induced myocardial
microvascular spasm. The MCE perfusion characteristics and the changes
of coronary spectrum had certain clinical value in the diagnosis of
myocardial microvascular spasm.
Selection of r-K strategies by soil bacterial communities in response to grassland degradation
Authors: Peng Junwei , Liu Hong , Hu Yang , Sun Yang , Liu Qin , Li Jiangang , Dong Yuanhua
Published: November 2021

Numerous studies have investigated bacterial community structure in
grassland ecosystems and bacterial community responses to human
management at various spatial and temporal scales; however, research on
soil bacterial community assembly dynamics in the course of grassland
degradation is limited. Here, the authors investigate the response and
assembly processes of bacterial communities adopted in two grasslands
with different degrees of degradation. Stochastic processes dominated
bacterial community assembly processes in response to grassland
degradation, with the bacterial diversity decreasing; however,
functional gene diversity increased. Furthermore, different phyla
exhibited distinct response strategies: Proteobacteria and
Bacteroidetes, as r-strategists, exhibited positive responses, with
increases in diversity, abundance, and niche width with an increase in
grassland degradation, enhancing biodiversity and productivity; other
phyla (mainly Acidobacteria) exhibited greater phylogenetic dispersion
and functional redundancy, and less niche overlap, highlighting the role
of K-strategy in improving community resource-use efficiency in response
to resource loss in degraded grasslands. The transition from K- to r-
strategy in bacterial communities following grassland degradation could
help communities adapt to environmental disturbance in the form of
nutrient loss. The results of the present study enhance our
understanding of how nutrient loss in natural grassland ecosystems leads
to shifts in bacterial community composition and assembly processes
mediated by different response strategies of different phyla.

Authors: Setiawan Moira , Wardoyo Suprayitno , Susanti Dhama Shinta , Makdinata William , Ardiansyah *
Published: November 2021

Around 3-4 children born with congenital heart diseases have
univentricular hearts, where the prognosis of univentricular hearts is
poor in the past, with a survival rate of less than 50% during the
first year and 10% during the first ten years of life. Based on a
literature search, current advances in perioperative management of
neonates with complex congenital heart diseases have increased their
survival rate by 85%. To aid cardiothoracic surgeons worldwide, this
comprehensive literature review will focus on the perioperative
management of staged palliation surgery for functional univentricular
hearts, considering current trends as well as how we do it in our
centre. Our review article specifially discusses perioperative
strategies regarding surgical considerations, current techniques, to
deal with overshunting and undershunting during the first stage of
palliation surgery. This article also gives an overview on when a
patient is suitable to go through with the next stage of the procedure,
which is the implementation of a bidirectional cavopulmonary shunt or
the Hemi-Fontan procedure. Lastly, this article gives a comprehensive
approach regarding perioperative strategies of the Fontan procedure,
which include patient criteria, current surgical techniques,
postoperative management, as well as the use of anticoagulants after the
Fontan procedure.

Published: November 2021

In this paper we consider a one-dimensional swelling porous-elastic
system with second sound and delay term acting on the porous equation.
Under suitable assumptions on the weight of delay, we establish the
well-posedness of the system by using semigroup theory and we prove that
the unique dissipation due to the delay time is strong enough to
exponentially stabilize the system when the speeds of wave propagation
are equal.
Interior crack initiation during the very-high-cycle fatigue of railway wheel steel under axial loading and rolling contact loading
Authors: Liu Xiao-Long , Gao Pengcheng , Wu Si , Zhang Guanzhen , Cong Tao
Published: November 2021

In this paper, a comparative study of the very-high-cycle fatigue (VHCF)
behavior of railway wheel steel under axial loading and rolling contact
loading was conducted. Fatigue tests were performed with an ultrasonic
fatigue test machine under axial loading, and the fracture surfaces from
the fatigue tests and shattered rims taken from the failed railway
wheels were observed. The wheel steel under axial loading presents a
VHCF behavior with Mode I crack, and that under rolling contact loading
is a VHCF behavior with mix Mode II-III crack. For the VHCF behavior
with Mode I crack ,surface and interior crack initiation occurred with
equal probability at both low and high stress levels and produced a dual
linear S-N curve since the value of fatigue limits for the surface and
interior crack initiation are close. For the VHCF behavior with mix Mode
II-III crack, cracks were initiated from the interior Al
O inclusion and the fatigue life was
beyond 10 cycles. Fatigue bands were observed on the
fracture surface under rolling contact loading. The ferrite nanograins
formed due to the stress state of shear plastic strain with a large
compressive stress. The formed nanograins were softer than the matrix
caused by the redistribution of the carbon.

Partial upper median sternotomy for anterior aortopexy for innominate artery compression syndrome: Our preferred technique.
Authors: Sainathan Sandeep , Murthy Raghav
Published: November 2021

Objectives: Innominate artery compression syndrome (IAS) is
caused by an anterior compression of the trachea by an abnormally
originating innominate artery. One option to relieve such a compression
is an anterior aortopexy (AA). In this paper we describe our technique
of an AA via a partial upper median sternotomy. Methods: A
retrospective review of a prospectively maintained database of patients
with IAS (July 2017 to November 2020) treated with AA via a partial
upper median sternotomy at University teaching hospitals in the US was
done. Results: Nine consecutive patients underwent AA for IAS
during the study period. The median age was 9 months (IQR 3- 16.5). The
male to female ratio was 1.25. All patients had > 70%
compression by flexible bronchoscopy. 2 patients had previous surgeries.
The follow-up was a median of 6 (IQR 4- 8.5) months. The indications for
the operation were: reflex apnea (4/9 patients), recurrent intubation
(4/9 patients), and severe stridor (1/9). IAS was a technical success
(defined as ≤ 20 % residual stenosis) in 78 % (7/9) of the patients.
Complete symptom resolution after an AA was seen in 71% (5/7) of the
patients. 2 patients had an unsuccessful AA, requiring a tracheal
resection and an innominate artery reimplantation, respectively.
Conclusion: An upper partial sternotomy approach provides a
very versatile approach to an AA for IAS. Besides facilitating an
adequate AA, it provides options for direct tracheal surgery or an
innominate artery reimplantation in case an optimal result is not
obtained by an AA.
