Una experiencia artística con tierra, barro y cerámica
Authors: Balanzà Ricard 
Published: December 2020

¿Qué es la cerámica? ¿Qué nos enseña de nosotros? ¿Está presente en nuestro entorno próximo y lo dota de identidad? ¿Qué de interés nos puede ofrecer en el ámbito educativo de primaria? ¿Qué campos de la expresión artística puede favorecer? Son algunas de las preguntas y reflexiones planteadas que motivan este ejercicio y tratamos de averiguar.
Los alumnos de tercero de Magisterio realizan dos piezas cerámicas utilitarias de distinto método de conformación y acabado, reflexionando sobre la educación artística, la creación y los procesos propios de la cerámica.
Para elaborarlas, se ha completado un proceso íntegro cerámico; partiendo de bocetos previos con una base gráfica tanto de forma como de texturas o motivos, con especial énfasis en los trazos básicos del dibujo en la infancia, su asimilación y translación al volumen (que ofrecen una enorme cantidad de recursos y posibilidades), el modelado en arcilla roja en masa plástica, la aplicación de engobes de una gama elemental de colores, la imprescindible cocción y su transformación metamórfica.
Se pretende, con este ejercicio, desarrollar la expresión artística mediante materiales y técnicas primigenias de nuestra historia, así como la percepción y la sensibilidad estética colectiva e individual, siempre des de un contexto universitario con enfoque a la enseñanza primaria y un alumnado en pleno desarrollo de conocimientos centrados en la exploración, la experimentación y la creación.
«In King Cambyses’ Vein»: Reconsidering the Relationship between Thomas Preston’s Cambises and Herodotus
Authors: Dall'Olio Francesco 
Published: December 2020

The relationship between Thomas Preston’s early Elizabethan tragedy Cambises (printed 1569) and the Book III of Herodotus’ Histories has often been downplayed, owing to the lack of printed editions or translations of Herodotus in England at the time and the much more evident connection between the tragedy and the second book of Richard Taverner’s Garden of Wysedome (1547). However, a closer look at the play’s sources reveals how a connection may exist, and how the version of the story Preston staged may be influenced by the tale of Cambyses as presented by the ancient historian. The insistence on the relationship between the king and his subjects (a central issue in both Preston’s tragedy and its sources) may derive from Herodotus, especially if viewed in contrast with the previous versions of the story in medieval literature, the focus of which was mainly on the ethical exempla they provided. Through a comparison of those texts, and a consideration of the availability of Herodotus’ work at the time, either in print or in manuscript form, this paper will then suggest that the version Preston staged in his tragedy is closer to Herodotus than the previous literary tradition.
La tutela degli orfani nelle Leggi di Platone: una risposta alle aporie della prassi ateniese
Authors: Oranges Annabella 
Published: December 2020

This paper addresses the guardianship of orphans in Plato’s Laws. The aim is to state whether the philosopher, through his theoretic model, wanted to correct the critical issues of the Athenian legal system that he perceived as most problematic. The paper is divided in two parts. The first one deals with the analysis of passages from Plato’s works in which the issue of the orphans’ guardianship had been addressed, in order to identify which related matters, in his opinion, deserved a corrective intervention. The second part of the paper is itself divided in two parts and deals with the analysis of the legislation on the orphans’ guardianship of Magnesia. The comparison with the Athenian and other institutions from the Greek world allows us to focus on the innovative features of this new legislation: they come out both from a personal revision by the philosopher and from the inspiration to non-Athenian models. In this way, Plato seems to try to fill the gaps of Athenian practice, even in theory.

Background
Recently, SARS-CoV-2 virus with the D614G mutation has become a public concern due to rapid dissemination of this variant across many countries. Our study aims were (1) to report full-length genome sequences of SARS-CoV-2 collected from four COVID-19 patients in the Special Region of Yogyakarta and Central Java provinces, Indonesia; (2) to compare the clade distribution of full-length genome sequences from Indonesia (n = 60) from March to September 2020 and (3) to perform phylogenetic analysis of SARS-CoV-2 complete genomes from different countries, including Indonesia.

Methods
Whole genome sequencing (WGS) was performed using next-generation sequencing (NGS) applied in the Illumina MiSeq instrument. Full-length virus genomes were annotated using the reference genome of hCoV-19/Wuhan/Hu-1/2019 (NC_045512.2) and then visualized in UGENE v. 1.30. For phylogenetic analysis, a dataset of 88 available SARS-CoV-2 complete genomes from different countries, including Indonesia, was retrieved from GISAID.

Results
All patients were hospitalized with various severities of COVID-19. Phylogenetic analysis revealed that one and three virus samples belong to clade L and GH. These three clade GH virus samples (EPI_ISL_525492, EPI_ISL_516800 and EPI_ISL_516829) were not only located in a cluster with SARS-CoV-2 genomes from Asia but also those from Europe, whereas the clade L virus sample (EPI_ISL_516806) was located amongst SARS-CoV-2 genomes from Asia. Using full-length sequences available in the GISAID EpiCoV Database, 39 of 60 SARS-CoV-2 (65%) from Indonesia harbor the D614G mutation.

Conclusion
These findings indicate that SARS-CoV-2 with the D614G mutation appears to become the major circulating virus in Indonesia, concurrent with the COVID-19 situation worldwide.

Methodology: Two field experiments were conducted on the Experimental Farm at El-Gemmeiza Research Station, Gharbia Governorate, Agricultural Research Center, Egypt, during two successive winter seasons of 2018-19 and 2019-20.
Aims: To investigate the effect of three nitrogen fertilizer rates, i.e. 30, 50 and 70 kg N feddan-1 [one feddan (fed) = 4200 m2] and three plant densities, i.e. 1500, 2000 and 2500 seeds m-2 on flax (Linum usitatissimum L.) yield and its quality of three cultivars of flax, i.e. Sakha 3, Giza 11 and Giza 12.
Results: Results in combined analysis of the two seasons showed that Sakha 3 cultivar significantly produced the maximum total plant height, technical stem length, upper branching zone length, No. of seeds capsule-1, total fiber percentage, fiber yield plant-1, fiber yield fed-1, fiber length and fiber fineness. Meanwhile, the highest No. of basal branches plant-1, straw yield plant-1, straw yield fed-1 and seed oil content were recorded with Giza 12 cultivar. While, Giza 11 cultivar gave the maximum stem diameter, No. of upper branches plant-1, No. of capsules plant-1, No. of seeds plant-1, seed index, seed yield plant-1, seed yield fed-1, harvest index, oil yield plant-1 and oil yield fed-1. Increasing nitrogen fertilizer rates from 30 up to 70 kg N fed-1 caused significant increases in almost straw, fiber, seed and oil yields and its related traits of flax, on the other hand, fiber fineness which significantly decreased with increasing nitrogen rates. Flax plants growing at 1500 seeds m-2 markedly gave the greatest No. of basal branches plant-1, stem diameter, straw yield plant-1, upper branching zone length, No. of upper branches plant-1, No. of capsules plant-1, No. of seeds plant-1, seed yield plant-1, harvest index, oil yield plant-1 and fiber yield plant-1. Meanwhile, the maximum total plant height, technical stem length, straw yield fed-1, seed yield fed-1, oil yield fed-1, total fiber percentage, fiber yield fed-1, fiber length and fiber fineness were obtained from flax planting at 2500 seeds m-2. The maximum fiber yield were recorded from the interactions among treatments Sakha 3 X 70 kg N fed-1, Sakha 3 X 2500 seeds m-2, 70 kg N fed-1 X 2500 seeds m-2 and Sakha 3 X 70 kg N fed-1 X 2500 seeds m-2. Meanwhile, the maximum seed and oil yields fed-1 were recorded from the interactions between treatments Giza 11 X 70 kg N fed-1, Giza 11 X 2500 seeds m-2, 70 kg N fed-1 X 2500 seeds m-2 and Giza 11 X 70 kg N fed-1 X 2500 seeds m-2.
Generally, it could be concluded that Sakha 3 cultivar under soil fertilized by 70 kg N fed-1 with plant density of 2500 seeds m-2 to maximizing fiber yield fed-1, while Giza 11 cultivar with the same rates of nitrogen and plant density to maximizing seed and oil yields fed-1.

Aims: To produce and optimize biosurfactants from Citrullus lanatus seeds.
Study Design: Randomized design.
Place and Duration of Study: Department of Biochemistry Lab. and Department of Microbiology lab. University of Nigeria, Nsukka, between April and August, 2017.
Methodology: Biosurfactants were produced in two fermentation media consisting of basal mineral medium+ watermelon (C. lanatus) seed (BMM+WMS), and Nutrient broth (NB). Optimization of production process was carried out with respect to time/duration of fermentation and pH of production which indicated 7 days fermentation period at pH 8.0. The Pseudomonas aeruginosa used was isolated from soil. The biosurfactants stability under some environmental conditions were studied using; Thermostability test at 30°C, 60°C, and 100°C; Halostability test with %w/v concentration of NaCl in; 2%NaCl, 5%NaCl, 7%NaCl, and 10%NaCl; pH stability test was conducted with pH 2.0, pH 4.0, pH 6.0, pH 8.0, pH 10.0, and pH 12.0.
Results: Proximate analysis(%) showed; protein (0.317­ ± 0.02), lipid (17.66 ± 0.17), carbohydrate (62.77 ± 0.21), ash (2.33 ± 0.24), fibre (4.84 ± 0.79), and moisture (12.06 ± 0.17).The Emulsification index (E24) for the crude biosurfactant solutions (supernatants) that resulted from the two production media, and sodium dodecyl sulfate 1% SDS in distilled water (control) using palm oil (PO), olive oil (OO), engine oil (EO), kerosene (KR), and petrol (PT) for BMM+WMS biosurfactant gave PO (79.66±1.52%), OO (64.66±7.23%), EO (15.33±4.93%), KR (12.66±6.50%), and PT (0.00±0.00%). Also, the NB biosurfactant resulted in; PO (71.00±2.00), OO (54.33±3.78), EO (42.66±6.42), KR (22.66±7.57), and PT (0.00 ± 0.00) E24 values. There were significant decreases (p<0.05) in biosurfactants activities in all vegetable oils and hydrocarbons when compared to the SDS surfactant. However, there was no significant decrease (p>0.05) in WMS biosurfactant activity in palm oil compared to SDS surfactant activity in palm oil.
Conclusion: The biosurfactants were shown to have high thermostablity as their E24 values increased with rise in temperature.

Published: December 2020

Background: Community empowerment is the process and outcome where community itself is able to identify, prioritize health problems and address them. It has been considered as the key strategy for scalability and sustainability of health services.
Objectives: To explore the status of community empowerment in health in rural areas in West Bengal, India and the interplay of different stakeholders.
Methods: A cross-sectional, qualitative study was conducted in 2017 – 2018 among the people residing in rural areas of Birbhum district in West Bengal, India who utilized the public health system (lay informants), formal and informal leaders of the community, community level health workers and peripheral health staff (key informants). Three community blocks, two sub-centers from each block and one village from each sub-center were selected randomly. In-depth interviews were conducted among 36 lay and 36 key informants using Laverack’s nine dimension model of community empowerment. Framework analysis was done to summarize data.
Results: Participation of people was restricted to awareness and utilization of existing health services. Unmet aspiration for greater participation was noted among a small section of the community. They were mostly fitted to the role of beneficiaries. Functioning of village level organization to promote communitization as envisaged in national health programmes was largely deficient. The community health workers acted as the most peripheral appendages of formal health system rather than the health activists to empower community regarding community’s health.
Conclusion: Although, every national health programme advocated community empowerment, the current status and the process of empowerment in health is in nascent stage.

Published: December 2020

AbstractBackgroundSeveral health conditions are associated with cement dust exposure; obstructive and restrictive lung disorders are the most common consequences. The aims of this study were to assess the pulmonary function of cement factory workers and to determine the distribution of respiratory consequences resulting from dust inhalation.MethodsA cross‐sectional study with convenience sampling was undertaken from December 2019 to March 2020. A total of 97 (response rate, 92.4%) nonsmoking male cement workers were recruited and compared with 97 apparently healthy volunteers. A spirometer was used to measure forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and their ratio (FEV1/FVC). The measured parameters were interpreted according to American Thoracic Society/European Respiratory Society guidelines.ResultsSignificant reductions were observed in pulmonary function parameters of cement factory workers compared to controls (FVC 4.03 vs. 4.65 L in controls; FEV1 3.06 vs. 3.95 L in controls; p < 0.001 for both comparisons). A significant variation was observed in the prevalence of spirometric patterns between the two participating groups. Ninety (92.8%) controls had normal respiratory function with no defects, compared with only 25 (25.8%) of the cement workers. Restriction was the most common respiratory problem, with a greater prevalence in the cement workers (44 [45.4%]) compared to six (6.2%) controls.ConclusionsCement factory workers showed decreased lung function and abnormal spirometric patterns which we attribute to dust inhalation. These workers should have periodic medical examinations and regular rotations through different factory departments to minimize the pulmonary hazards of cement dust.

Published: December 2020

AbstractThe development of a diastereoselective intramolecular rhodium‐catalyzed [(3+2+2)] carbocyclization reactions of allyl ester‐tethered alkynylidenecyclopropanes (ACPs) for the construction of the 5,7,5‐tricyclic scaffold of the tremulane sesquiterpene natural products is described. This work illustrates that the stereoelectronic nature of the phosphite ligand is critical for attaining high levels of stereocontrol, which is supported by density functional theory (DFT) studies that indicate the migratory insertion step favors the formation of the cis‐diastereoisomer. Consequently, several strategies were devised to access the thermodynamically more stable trans‐diastereoisomer for the synthesis of the tremulanes; however, the attempts to either switch the sense of stereocontrol in the carbocyclization reaction or epimerize the C7 stereocenter of the cycloadduct provided only modest improvements. Hence, we elected to highlight the synthetic utility of this strategy with the development of concise and highly efficient syntheses of (±)‐epi‐tremulenolide A, (±)‐epi‐tremulenediol A and (±)‐epi‐ceriponol D.
Ruptured caseous calcification of the mitral annulus
Authors: Allwood Richard P. , Bonacci Emma L. , McKinnon Erin 
Published: December 2020

AbstractMitral annular calcification (MAC) is considered a chronic and degenerative process involving the fibrous annulus of the mitral valve. The prevalence of MAC has been reported between 8% and 15%. It significantly increases with age, often seen in females, individuals with hypertension, chronic kidney disease and those with multiple cardiovascular risk factors. Caseous calcification of the mitral annulus (CCMA) (also known as caseoma) is a rare variant of MAC and should be considered in the differential diagnosis with other cardiac masses of the mitral valve.An 85‐year‐old female presented for a transthoracic echocardiogram with a history of hypertension and a systolic murmur. The echocardiogram demonstrated a possible rare variant of MAC, with independent mobile echodensities identified. Further testing using transoesophageal echocardiography was used to confirm diagnosis and ensure appropriate clinical management was arranged.This case demonstrated CCMA, a benign condition that can be mistaken for cardiac tumours, thrombus, vegetations or abscesses. A low prevalence has been reported between 0.06% and 0.07% and 0.6% of patients with MAC using echocardiography. Echocardiography can provide the initial diagnosis for identification and characterisation of MAC. CCMA appears as a calcified mass with an echolucent, liquid‐like inner part, located on the posterior mitral valve annulus. Acoustic shadowing is usually absent. Multi‐modality imaging can lead to an accurate diagnosis of CCMA without unnecessary interventions. Transoesophageal echocardiography provides further information on the site and composition of the internal material. Computed tomography (CT) and cardiac magnetic resonance imaging (MRI) can also be used, to confirm the diagnosis and to exclude other differential diagnoses.

Abstract

Background
We examined overall survival (OS) outcomes based on plasma 25-hydroxyvitamin D [25(OH)D] levels in this post hoc analysis of the phase III MPACT trial of metastatic pancreatic cancer.

Materials and Methods
Patients were subdivided based on 25(OH)D level: sufficient (≥30 ng/mL), relatively insufficient (20–&lt;30 ng/mL), or insufficient (&lt;20 ng/mL).

Results
Of 861 patients randomized in MPACT, 422 were included in this analysis. In the all-patients group, the median OS among those with insufficient, relatively insufficient, and sufficient 25(OH)D levels was 7.9, 9.4, and 7.8 months, respectively. No statistically significant OS difference was observed with relatively insufficient (p = .227) or sufficient (p = .740) versus insufficient 25(OH)D levels or with sufficient vs relatively insufficient (p = .301) 25(OH)D levels.

Conclusion
No association was observed between plasma 25(OH)D levels and survival. Further investigations are needed to understand any role of vitamin D in pancreatic cancer. Clinical trial identification number. NCT00844649.
