Authors: Piccinini Pedro , de Sousa Rebelato Mariana , Masri Marwan , Uebel Carlos , Stümpfle Rubem , de Oliveira Milton
Published: December 2021

More than 400 million patients worldwide are affected by diabetes; over their lifetime, at least 25% will develop foot ulcers that often result in high rates of nonhealing wounds and amputation. The authors present the case of a 43-year-old female patient with multiple comorbidities who presented with a large (8 cm x 4 cm), noninfected, hindfoot plantar ulcer that extended down to the bone and calcaneus. Over 2 weeks, the patient was successfully treated using a combination of an acellular dermal matrix, nanofat grafting, and negative pressure wound therapy, lessening the effects of the ulcer on the patient’s quality of life and achieving limb salvage. Utilizing the regenerative procedures described herein may improve patient care and decrease costs.

Our study aimed at deepen our understanding of relationships between soil properties and vegetation distribution in metalliferous ecosystems of Tenke-Fungurume in the Democratic Republic of Congo. The first question concerned the differences and similarities between soils of the main vegetation units and four variation factors of soil properties were summarized by multivariate analysis. They were all linked to lithology and significantly contributed to explain the distribution of vegetation units. Our result suggest that the variation of soil properties which is observed within the various vegetation units (rocky steppe savanna, sward, and steppe savannas on slope or on Dembo) should partially be attributed to differences of geochemical composition of rocks between sites but the main source of variability is to be found inside each hill. The soil contamination in Cu and Co originates from rock weathering and besides site effect and topographic distribution of the rocks, the variability of soil properties within one vegetation unit may be due to variability of soil parent material and not only to erosion. The second question dealt with the changes of soil properties at small distances. Metric variation was studied from transects between adjacent vegetation units. Our results showed that the abrupt changes of vegetation units which were clearly identified on the field were all truly explained by the variations of one or more properties linked to lithology. The key point being the Cu bioavailability.

Hereditary low-mode dynamo model
Authors: Казаков Е.А.
Published: December 2021

В данной статье рассматривается модель динамо в виде двумерной динамической системы в интегро-дифференциальной форме. В модели реализован стабилизирующий генерацию поля механизм обратной связи в виде подавления α-эффекта функционалом сверточного типа от актуальных и предыдущих значений спиральности и энергии. Наличие этого механизма подавления вводит в модель эредитарность (память). Для модели была построена численная схема ввиде совмещение разностных схем для дифференциальной и интегральной части, двухступенчатый неявный методы Рунге-Кутты и метод трапеций соотвественно. Так же были рассмотрены и графически представлены динамические режимы нашей модели.

This article discusses a dynamo model in the form of a two-dimensional dynamical system in integro-differential form. The model implements a stabilizing polarization generator in the form of suppression of the a effect of convolutional type functional from current and previous helicity and energy values. The presence of this suppression mechanism introduces hereditarity (memory) into the model. For modeling, a digital scheme was constructed in the form of a combination of difference schemes for the differential and integral parts, a twostep implicit Runge-Kutta method and a trapezium method, respectively. We also reviewed and graphically presented the dynamic modes of our model.

Machine learning to explain printability induced by rheology additives
Authors: Nadernezhad Ali , Groll Jürgen
Published: December 2021

With the continuous growth of extrusion bioprinting techniques, ink formulations based on rheology modifiers are becoming increasingly popular, as they enable 3D printing of non-printable biologically-favored materials. However, benchmarking and characterization of such systems are inherently complicated due to the variety of rheology modifiers and differences in mechanisms of inducing printability. This study tries to explain induced printability in formulations by incorporating machine learning algorithms that describe the underlying basis for decision-making in classifying a printable formulation. For this purpose, a library of rheological data and printability scores for 180 different formulations of hyaluronic acid solutions with varying molecular weights and concentrations and three rheology modifiers were produced. A feature screening methodology was applied to collect and separate the impactful features, which consisted of physically interpretable and easily measurable properties of formulations. In the final step, all relevant features influencing the model’s output were analyzed by advanced yet explainable statistical methods. The outcome provides a guideline for designing new formulations based on data-driven correlations from multiple systems.
Dissociation pathways of the p53 DNA binding domain from DNA and critical roles of key residues elucidated by dPaCS-MD/MSM
Authors: Sobeh Mohamed , kitao Akio
Published: December 2021

The dissociation process of the DNA binding domain of p53 (p53-DBD) from a DNA duplex that contains the consensus sequence, which is the specific target of p53-DBD, was investigated by a combination of dissociation parallel cascade selection molecular dynamics (dPaCS-MD) and the Markov state model (MSM). Based on an all-atom model including explicit solvent, we first simulated the p53-DBD dissociation processes by 75 trials of dPaCS-MD, which required an average simulation time of 11.2 ± 2.2 ns per trial. By setting the axis of the DNA duplex as the Z-axis and the binding side of p53-DBD on DNA as the + side of the X-axis, we found that dissociations took place along the +X and −Y directions (−Y directions) in 93% of the cases, while 7% of the cases moved along +X and +Y directions (+Y directions). Toward the −Y directions, p53-DBD dissociated first from the major groove and then detached from the minor groove, while unbinding from the minor groove occurred first in dissociations along the +Y directions. Analysis of the free energy landscape by MSM showed that loss of the minor groove interaction with p53-DBD toward the +Y directions incurred a relatively high energy cost (1.1 kcal/mol) upon a critical transition, whereas major groove detachment more frequently occurred with lower free energy costs. The standard binding free energy calculated from the free energy landscape was −10.9 ± 0.4 kcal/mol, which agrees with an experimental value of –11.1 kcal/mol. These results indicate that the dPaCS-MD/MSM combination can be a powerful tool to investigate dissociation mechanisms of two large molecules. Minor groove binding is mainly stabilized by R248, identified as the most important residue that tightly binds deep inside the minor groove. Analysis of the p53 key residues for DNA binding indicates high correlations with cancer-related mutations, confirming that impairment of the interactions between p53-DBD and DNA can be frequently related to cancer.

How Many 'Clicks' Does it Take? Finding Price Information on New Zealand Lawyers' Websites
Authors: Choe Louisa
Published: December 2021

This article examines price transparency in New Zealand's civil legal services market and compares the civil legal services market characteristics to those of other jurisdictions. The current law does not incentivise providers within the legal services market to communicate price information to consumers searching for a provider. The researcher utilised a web-sweep method to assess how New Zealand law firms that provide dispute resolution services and employment advocates share information through their websites. The web-sweep covered the websites of 96 New Zealand law firms and 30 New Zealand employment advocates. The author assessed the ease with which prospective consumers could navigate and understand price-related information. The results demonstrated that in a majority of instances, price information is unclear and uncertain. It is therefore not comparable between providers. Consumers in New Zealand face a high search cost when looking for prices and deciding on a legal service provider. They are unable to make a meaningful price comparison between providers of dispute resolution services before engaging them. Stronger regulation of providers (lawyers and employment advocates) to require the display of pricing information would lower search costs for consumers and increase competition.

Putusan Mahkamah Konstitusi (MK) Nomor 22/PUU-XV/2017 membawa angin segar bagi para pencari keadilan di negeri ini. Majelis hakim MK menetapkan bahwa pasal 7 ayat (1) Undang-Undang Nomor 1 tahun 1974 tentang Perkawinan pada frasa “usia 16 (enam belas) tahun bertentangan dengan Undang-Undang Dasar NRI tahun 1945 dan tidak mempunyai kekuatan hukum mengikat serta memerintahkan kepada legislatif untuk melakukan perubahan terhadap Undang-Undang perkawinan khususnya pada rumusan batas minimal usia perkawinan bagi perempuan dalam jangka waktu paling lama 3 (tiga) tahun. Setelah rumusan batas minimal perkawinan bagi perempuan ini dibatalkan oleh Mahkamah Konstitusi, selanjutnya patut ditelaah dan dianalisis bagaimana konsekuensi dan dampak putusan tersebut bagi Undang-Undang Perkawinan dan peraturan-peraturan yang terkait. Idealnya setelah putusan Mahkamah Konstitusi ini dimuat dalam berita negara Indoneisa maka para pembentuk Undang-Undang segera melaksanakan kehendak putusan tersebut demi menciptakan keadilan dan kesejahteraan bagi masyarakat Indonesia.
EKSISTENSI ALIRAN POSITIVISME DALAM ILMU HUKUM

Published: December 2021

Positivisme adalah suatu paham filsafati dalam alur tradisi pemikiran Galilean (atau Newtonian), yang bertolak dari anggapan aksiomatik bahwa alam semesta ini pada hakekatnya adalah suatu himpunan fenomenon yang saling berhubungan secara interakltif dalam suatu jaringan kausalitas, yang dinamis, deterministik dan makanistik. Fenomenon yang satu sebagai penyebab fenomenon yang lain. Positivisme hukum artinya hukum dipositifkan sebagai status tertinggi diantara berbagai norma (the supreme of law), yang terdiri dari berbagai perbuatan sebagai fakta hukum dengan konsekuensinya yang disebut akibat hukum. Positivisme jurisprudence atau positivisme ilmu hukum adalah ilmu pengetahuan tentang kehidupan dan perilaku warga masyarakat yang sudah semestinya tertib mengikuti norma-norma kausalitas. Positivisme mempunyai keunggulan yaitu kepastian hukum yang prediktabel adanya jaminan kepastian hukum dan ketetapan dalam hal ‘nilai’ artinya hukum yang tertulis, pasti dan jelas maka eksistensinya dipertahankan sampai sekarang, bahkan masa yang akan datang.

Published: December 2021

Several factors may account for the recent increased spread of the SARS-CoV-2 Delta sub-lineage AY.4.2 in the United Kingdom, Romania, Poland, and Denmark. We evaluated the sensitivity of AY.4.2 to neutralisation by sera from 30 Comirnaty (BNT162b2 mRNA) vaccine recipients in Denmark in November 2021. AY.4.2 neutralisation was comparable to other circulating Delta lineages or sub-lineages. Conversely, the less prevalent B.1.617.2 with E484K showed a significant more than 4-fold reduction in neutralisation that warrants surveillance of strains with the acquired E484K mutation.

Doctoral Students’ Learning Experiences in Ghana: Exploring a New Curriculum Using Bourdieu’s Concepts
Authors: Salifu Inusah , Seyram Agbenyega Joseph
Published: December 2021

Aim/Purpose: To utilize Pierre Bourdieu’s (1984, 1986) concepts of capitals, habitus, and field to explore and critically analyze doctoral students’ learning experiences with a new doctoral curriculum introduced by a Ghanaian university.

Background: Global competition and labor market reforms have ignited the need for higher education institutions to reimagine their doctoral programs, develop and align them with labor market demands and national priorities.

Methodology: The research was conducted as a qualitative inquiry based on which the purposive sampling technique was used with 18 doctoral students from a Ghanaian university. Participants took part in individual interviews and data were analyzed using thematic coding procedures developed based on Bourdieu’s (1984; 1986) theorization of capital, habitus, and field

Contribution: The study may benefit universities in monitoring the quality of doctoral students’ learning experiences.

Findings: The research found that, although the participants were broadly satisfied with some aspects of their programs, the additional cost associated with its duration, the lack of quality and timely feedback from supervisors, and difficulty accessing conference funding were key challenges to achieving the ultimate goals of the new doctoral curriculum.

Recommendations for Practitioners: The paper draws attention to human dispositions, values, and beliefs (habitus) which operate with different forms of capital in fields of doctoral training.

Recommendation for Researchers: Researchers may focus on tools that help to transform supervisor habitus and the kinds of support that work for individual students.

Impact on Society: The strongest message gleaned from this study is that to improve doctoral students’ learning experiences, it is necessary first to develop a student-supervisor relationship built on mutual respect, clear timelines for achieving supervision targets, and commitment to achieving the targets. The research further challenges the higher education system in Ghana and in deed, the world at large, to look beyond the objectified capital (certificates) and to develop relevant skills that students require to be professionally ready for the labor market.

Future Research: One of the study’s limitations is that the sample was selected from one university in Ghana. Future research may compare doctoral curriculums and students’ learning experiences across several Ghanaian universities. Again, this research used the perspectives of only students. A future study may draw on multiple perspectives to provide depth and breadth of knowledge on the doctoral program.

Published: December 2021

La fotocatálisis heterogénea utilizando TiO2, es una técnica de degradación de contaminantes orgánicos presentes en los efluentes de aguas residuales. Estudios previos reportan que el proceso de UV/TiO2 es capaz de descomponer eficientemente varios alquenos clorados y otros compuestos orgánicos. Estudios previos han mostrado que el uso de nanopartículas mejora las actividades fotoactivas con respecto a sus contrapartes de fase en masa. La incorporación de dopantes de metales de transición en la estructura del TiO2 puede influir en el rendimiento de estos fotocatalizadores al modificar la energía de la brecha prohibida. En este trabajo se presentan los resultados de la síntesis de soluciones sólidas Ti1-xMnxO2, donde 0.02£x£0.7, mediante la técnica sol-gel. Los estudios de difracción de rayos X mostraron la estabilidad de la fase anatasa en las diferentes concentraciones de Mn2+ analizadas (Ti1-xMnxO2; x=0.02-0.05) a 500°C y confirmaron la naturaleza nanocristalina de los materiales. Las energías de banda prohibida, mostraron una disminución de sus valores conforme aumenta la concentración de manganeso.

Published: December 2021

En este artículo se compararon las características de un mortero generado sustituyendo el cincuenta por ciento de su volumen de arena por uno similar de zeolita con respecto a una mezcla control a la que no se le agrego zeolita. Esto con el objetivo de establecer si la presencia de dicho material modificaba el comportamiento del mortero con respecto a su humedad interna, así como establecer si la capacidad de absorción reversible de la zeolita seguía activa a pesar de encontrarse integrada dentro de una pasta cementante. Para lograrlo, a muestras de ambas mezclas se les hizo la prueba de absorción de humedad máxima inicial y la de absorción total a 24 horas, determinando también su humedad interna a lo largo del día para así establecer si se presentaban diferencias en ambos materiales, ante la humedad ambiental. Finalmente, los resultados obtenidos si demostraron claras diferencias en todas las pruebas realizadas a favor de la mezcla con zeolita, por lo que se concluyó que la hipótesis era correcta.

Authors: Fitriani Fitriani
Published: December 2021

This study aims at analyzing the violation of the maxim of quantity produced by undergraduate students in research seminar and the reason why they violate this kind of maxim. The researchers applied qualitative research design by using observation and in-depth interview. Four undergraduate students were the participants of this research recruiting using purposive random sampling. The results show that most of the participants violated the maxim of quantity by doing circumlocution (not to the point), providing more explanation, and talking too much. They considered that it was valuable for them to provide more information than needed to obtain the attention of the examiners. They assume that the more they speak the good outcome for their research seminar will be accomplished because having more explanation means they master their research content well.

The Coastal Fishing Port Sadeng is located in Girisubo District, Gunung Kidul Regency, Yogyakarta. The Coastal Fishing Port Sadeng plays a role to support the development of marine fisheries in the Special Region of Yogyakarta Province. The initial information obtained was that at The Coastal Fishing Port Sadeng, fishing actors did not comply with licensing documents. The purpose of this study was to determine the problem and assess the level of compliance of fishing’s actors in The Coastal Fishing Port Sadeng, which has fishing vessels with a size of more than 5 GT, to the applicable regulations in the marine and fisheries sector. The method used in this research is a case study on the compliance of fishing vessels at The Coastal Fishing Port Sadeng. The data analysis used is descriptive analysis. The results of the study stated that the level of compliance of fishing vessels in Coastal Fishing Port Sadeng to the ownership of SIUP licensing documents was 97.14% (very good), SIPI 51.43% (very poor), SLO 48.57% (very poor), and SPB 31.43 % (very less). Licensing documents that are not owned or have expired and the incompatibility of documents with the physical ship are problems that cause the level of compliance of fishing business actors at Coastal Fishing Port Sadeng to be considered very low.

Pembenihan merupakan suatu kegiatan dalam budidaya ikan yang dalam pengembangannya sering mengalami berbagai kendala, diantaranya ialah tingginya kematian larva. Hal ini disebabkan karena larva yang memiliki bukaan mulut yang sangat kecil sehingga sulit mengkonsumsi pakan yang sesuai. Upaya yang dapat dilakukan untuk mengatasi masalah tersebut adalah dengan menyediakan pakan yang sesuai dengan bukaan mulut larva. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh pemberian tepung cangkang rajungan yang terfermentasi terhadap pertumbuhan populasi Daphnia sp. Penelitian ini dilaksanakan pada bulan Maret sampai bulan April 2020 yang di km.4 Nagori Wonorejo Kecamatan Pematang Bandar Kabupaten Simalungun Provinsi Sumatera Utara.

Laryngeal cancer is the second most common cancer after the lip and oral cavity cancer ofhead and neck region1. Laryngeal malignancy is the seventh most common malignancy in males in India. Total number of new laryngeal cancer and death from laryngeal cancer have been estimated 12410 and 3760 respectively in 20192. As per last survey available the number of new cases diagnosed and total number of deaths from laryngeal malignancy were 25,460 and 17,560 respectively in 2012 in India3 . The incidence of cancer larynx is 1.26-8.18 per 100,000 populations in different regions of India. Carcinoma larynx constitutes40% of all Head and Neck cancers. Squamous cell carcinoma constitutes 95% of all malignancies of larynx. Glottis being the most common subsite followed by supraglottis and the least common site is the subglottis. There is an increasing incidence rate of this malignancy among middle aged and elderly men and women throughout the world. Expression of Biomarkers at different stages of laryngeal cancers and their impact on survival can play a crucial role in future management of laryngeal malignancies. In spite of having different modalities of treatments like surgery, radiotherapy, chemoradiation, the prognosis of laryngeal malignancies is still poor. The most common adverse factor for laryngeal cancer has been found lymph node metastasis. The process of progression of LSCC is complex and difficult to know it completely. Despite multi-modality therapeutic advances in recent decades, improvements in overall survival and disease free survival is very less. In this study we emphasized the role of expression of biomarkers vimentin and metastasis associated 1(MTA1) protein in different stages of laryngeal cancer and their impacts on survival.

Published: December 2021

The levels of physicochemical properties of Mini Whuo Stream in Port Harcourt, Rivers State, Nigeria was evaluated. The physicochemical parameters were analyzed using standard conventional procedures. The average values recorded for the physicochemical parameters during the months of investigation were in the range; temperature; 30.00±0.42-30.26±0.83oC, with all-round mean of 30.14±0.47oC, pH; 6.22±0.33-6.42±0.25 (6.29±0.29), electrical conductivity; 146.01±74.04-147.26±75.13µS/cm (146.58±74.69 µS/cm), total alkalinity; 61.63±6.37-62.20±6.41mg/L (61.91±6.41 mg/L), sulphates; 109.67±51.34-110.67±51.88mg/L (110.22±51.81 mg/L), nitrates; 12.20±2.38-12.60±2.86mg/L (12.31±2.65 mg/L), turbidity; 49.32±1.49-50.18±2.02 NTU(49.83±1.55 NTU), TDS; 74.20±36.43-75.61±37.50 mg/L (75.00±36.81 mg/L), TSS; 27.14±2.12-28.37±0.78mg/L (27.64±1.89 mg/L), chlorides; 15.17±2.90-15.66±2.70mg/L (15.34±2.65 mg/L) and salinity; 24.36±4.83-24.82±4.97mg/L (24.66±4.78 mg/L). The evaluation of the physicochemical parameters showed that the Mini Whuo Stream has been contaminated due to human activities within the stream and therefore adequate measures should be taken to forestall the present situation of the stream in order to mitigate any possible increase in deterioration of the studied physicochemical parameters in the stream beyond acceptable limit.

Peleo nel libro XI delleMetamorfosidi Ovidio
Authors: Romeo Alessandra
Published: December 2021

The paper focuses on Peleus as a marker character in narrative diegesis of Ovid’sMetamorphoses, i.e. a character who shifts the narrative action in the plot of the poem. This function is extensively articulated in Book 11 where Ovid creates a narrative interstice, that of Peleus in exile at the court of Ceyx at Trachis (met.11. 266-409). Peleus and Ceyx’s episode is compiled by Ovid in the form of the dramaturgical episode which includes four characters acting and interacting (Peleus, Ceyx, Onetor, Alcyone). Ovidian reinvention of the 'facts of Peleus', a mythological subject of consistent poetic background, exemplifies the narrative organisation of the innovative epic of theMetamorphoses, and reveals some aspects of Ovid’s literary self-consciousness.
Optazianismi. Elementi formulari di un poeta visuale
Authors: Manca Massimo
Published: December 2021

In poetry, particularly in the hexametric one, the use of formulas determines the stylistic fingerprint of an author. The contribution examines the poetic material used by the Constantinian poet Optatianus Porfyrius, trying to identify formulas and motifs peculiar to this author, employed by him several times, or even introduced by him for the first time, some of which appeared successful in the later tradition. The figure of an author well integrated into the poetic tradition emerges, but not without an inventive spirit and auctoritas.
Paradeigmata voluntatis
All’origine della concezione moderna di volontà
Authors: Cattanei Elisabetta , Maso Stefano
Published: December 2021

‘Will’ descends, etymologically, from voluntas. However, in the meaning of voluntas
it is no longer possible to grasp the terminological plurivocity present in the Greek
language. Consequently, the theory of action, which Aristotle and Greek thought in
general had extensively dealt with, in the Roman context has adapted to a simplified
conceptual framework. The essays collected here have allowed us to focus on a
brand new articulated paradigm. Within it, we find a renewed concept of ‘will’: the
voluntas which is explained in the modern interpretation of the ‘voluntary act’, and
‘voluntarism’ tout-court.
Arms and Armour in Ancient and Medieval Tibetan Literature
A Lexicographical Approach
Authors: Maurer Petra
Published: December 2021

This article presents Tibetan terms and expressions for arms and armour originating in Tibetan sources as per research conducted for the Wörterbuch der Tibetischen Schriftsprache, a dictionary database that includes sources ranging from the eight to the nineteenth centuries. This survey shows that Tibetan literature bears testimony to the existence of a broad variety of arms and armour in Tibet, which are mentioned in various contexts: Bon or Buddhist sources, historiographical or mythical accounts. By tracing these terms’ etymological origins and focusing on the actual use of weapons, we may gain a clearer understanding of the origin, use, and value of arms and armour in Tibetan culture.
The Dorjéling Armoury in the Potala According to the Fifth Dalai Lama’s gsung ’bum
Authors: Venturi Federica
Published: December 2021

Although the government established through the alliance of the Gélukpa (Dge lugs pa) and the Khoshud in 1642 took its appellation from the Ganden Palace (Dga’ ldan pho brang/Ganden Phodrang) at Drepung (’Bras spung), the symbolic seat of power of this government was the Potala, at the same time fortress, administrative centre, earthly copy of the celestial palace of Avalokiteśvara, and official residence of the Fifth Dalai Lama. Less known, however, is that the Potala also came to symbolise military readiness. It acquired this new martial function in 1667, when an armoury, called Dorjéling (Rdo rje gling), was set up at the base of the White Palace. The Fifth Dalai Lama memorialised its establishment with a poetic text, which is included in volume nineteen (ma) of his collected works. This paper examines this text, which provides information both on the contents of the armoury and on the logic employed to justify the creation of spaces dedicated to military preparedness within a palace that was fast becoming one of the most revered sites in the Tibetan sphere.
