O Coletivo Margarida Alves e a Associação dos Pequenos Produtores Rurais do Assentamento Olga Benário (ASPROAB) em Ipameri (GO):
Authors: Monteiro Rafael de Melo , Aparecido Teodoro Borges Luciney 
Published: August 2021

O objetivo desse artigo é compreender, pela análise do Coletivo Margarida Alves e da ASPROAB, as disputas de poder em torno do trabalho e da produção do território no Assentamento Olga Benário, em Ipameri (GO). O aporte teórico-conceitual parte das discussões sobre território e relações de poder, com base em autores como Foucault, Raffestin e Saquet, além dos que tratam do campesinato e dos assentamentos rurais, a exemplo de Woortmann, Turatti, Pessoa e Ferrante, entre outros. Na pesquisa de campo, foram realizadas 55 entrevistas semiestruturadas, entre janeiro e maio de 2015. Em 2019, foram feitas, também, 20 entrevistas com membros da ASPROAB. O trabalho se tornou eixo central das relações de poder e da produção do território no Assentamento Olga Benário, investido em diferentes projetos políticos: de um lado, a recusa do assentamento coletivo, pela maioria das famílias, e a adesão ao modelo associativo, que conserva a posse da terra e a organização familiar do trabalho, com a preocupação de assegurar a estabilidade de vida na terra; por outro lado, o Coletivo Margarida Alves, a despeito do seu desfazimento, também imprimiu sua importância na dinâmica histórica do assentamento, por sua proposta alternativa de trabalho e terra coletivos, sintonizada com a perspectiva de transformação social do MST.

From Earthquake Geophysical Measures to Insurance Premium: A Generalised Method for the Evaluation of Seismic Risk, with Application to Italy’s Housing Stock
Authors: Cesari Riccardo , D’Aurizio Leandro 
Published: August 2021

Abstract
Following the increasing necessity of quantitative measures for the impact of natural catastrophes, this paper proposes a new technique for a probabilistic assessment of seismic risk by using publicly available data on the earthquakes that have occurred in Italy. We implement an insurance-oriented methodology to produce a new map of the seismic risk and to evaluate, under various hypotheses, the costs of insuring all the Italian housing units against it. The model is compared with two main privately developed models, well known in the reinsurance industry, providing fairly similar results.
Extremely preterm infant with persistent peeling skin: X-linked ichthyosis imitates prematurity
Authors: Burcescu Brigitte , Brumberg Heather L. , Shah Shetal I. 
Published: August 2021

Abstract

Objectives
X-linked ichthyosis (XLI) is a genetic disorder caused by a deficiency in steroid sulfatase, an enzyme which catalyzes a reaction in estrone synthesis. The disorder primarily manifests as dry, scaly skin which may be difficult to diagnose in extremely preterm infants, as the dermatological features may be falsely attributed to a normal variant of skin for this population.

Case presentation
In this case report, we describe a male with XLI, born at 24 weeks gestation, who had persistent dry, flaky and hyperpigmented skin. This case is notable for the age of diagnosis in an extremely premature infant; day of life 105. In addition, this infant experienced out of proportion bronchopulmonary symptoms that we postulate may be linked to the steroid sulfatase deficiency, as estrogen is a mediator of surfactant production.

Conclusions
This report underscores the need to potentially evaluate persistent dry, flaky skin in the preterm infant, as XLI may also impact long term neurodevelopmental outcomes.
Mineralization treatment of European oak heartwood with calcium oxalate for improved fire retardancy
Authors: Franke Tom , Volkmer Thomas 
Published: August 2021

Abstract
Within the focus to apply substances for wood protections, here fire retardants, with low hazardous and low environmental impact is of interest. Additionally, European oak is an attractive species for various interior and exterior applications. However, oak is classified as very heavily treatable and thus impregnation is challenging. However, the focus of this study was to treat European oak with a new fire retardant based on an in-situ calcium oxalate deposition. Thin oak specimens with a thickness of 4 mm were investigated with two various formulations of aqueous salt solutions (potassium oxalate and calcium chloride, and potassium oxalate and calcium acetate) to obtain an in-situ mineralization of calcium oxalate during a two-step impregnation process. The uptake, the distribution, and the penetration of the salts for both applied formulations were investigated. Additionally, fire retardant properties were investigated in a single flame source test. It could be demonstrated that an acceptable degree of treatability was achieved for both applied formulations. The fire retardancy of the so mineralized material was clearly improved. Synergetic effects which might be caused by the reaction side products of the various formulations were found to be neglectable.

Abstract

Objectives
Growing interest has been reported on the health benefits of fermented foods, which includes cognition enhancement and inflammation attenuation. BDNF is a known protectant against retinal degeneration, however, therapies that target this neurotrophic factor has been limited. Therefore, we assessed the reaction of BDNF and glial cells in glaucomatous rats and their response to treatment with fermented maize products.

Methods
Thirty male adult rats were either injected via the episcleral vein with hypertonic saline to elevate intraocular pressure (IOP) or treated with fermented maize slurry (Ogi) or its supernatant (Omidun). Following sacrifice, the retina and duodenum were studied by immunohistochemical analysis using antibodies directed against GFAP, AIF-1 and BDNF.

Results
Hypertonic saline injection produced hypertrophy of the Müller cells and increased GFAP and AIF-1 expression in the retina and gut when compared to the control. Treatment with Ogi and Omidun produced varying degrees of reduction of gliosis, protection against hypertonic saline-induced retinal ganglion cell loss, and reduced intraocular pressure. BDNF expression was downregulated following the hypertonic saline assault, while Omidun and Ogi treatment abrogated its reduction following the hypertonic saline assault.

Conclusions
Collectively, our findings suggest that acute elevation of IOP alters crosstalk between gut and retina with consequent aberrant activation of glial cells; and that probiotic bacteria like the lactic acid bacteria rich in fermented foods including Ogi and Omidun may offer neuroprotection to the ganglionic cells by attenuating the retinal glial reaction and improving BDNF activity.
Sustainable coatings on paper for enhancing barrier properties based on hemicellulose
Authors: Li Yanan , Wu Rina , Shi Jiahui , Wang Gaosheng 
Published: August 2021

AbstractCoated paper with enhanced barrier properties was prepared via a simple layered self-assembly method using hemicellulose and starch as biobased coatings. Effect of the coating on properties of cellulose paper was investigated. Barrier properties of the paper was increasingly strengthened as the coating amount of hemicellulose rose. When the paper was coated with starch (10.7±0.3 g/m2\text{g}/{\text{m}^{2}}) and hemicellulose (6.9±0.2 g/m2\text{g}/{\text{m}^{2}}) successively, the oil resistance of the paper was increased from 0 to grade 7. Air permeability and water vapor transmittance was decreased by 93.8 % and 39.7 %, respectively. The water contact angle of the coated paper reached 91.7° when the amount of hemicellulose was 1.5±0.2 g/m2\text{g}/{\text{m}^{2}}. The hydrophobicity of the coated paper was superior to the original paper although it was negatively influenced by the increasing amount of hemicellulose. The improvement of barrier properties of the coated paper was mainly ascribed to the formation of a thin polymer network on paper surface through intermolecular interaction via hydrogen bonds as demonstrated in SEM and FTIR-ATR results. Moreover, tensile strength and rupture resistance of the coated paper was improved. The results offered an environmentally friendly and economical strategy for preparation of food packaging paper with good barrier properties using biobased coating materials.
Lignin reinforced, water resistant, and biodegradable cassava starch/PBAT sandwich composite pieces
Authors: Wang Liang , He Jun , Wang Qingdong , Zhang Jing , Feng Jie 
Published: August 2021

Abstract
Following the stipulation to replace nondegradable plastics with biodegradable materials in China, cost-effective and water-resistant packaging materials have become increasingly necessary. In this work, lignin reinforced thermoplastic cassava starch (TPS) pieces were prepared by filling glycerol and lignin powder into starch via a melt blending process and then being pressed into thin pieces. A mechanical properties test showed that following the addition of 3 wt% lignin, the tensile strength of the TPS piece was improved to 16.15 MPa from 3.71 MPa of the original TPS piece. The porous structures of the lignin powder tie the TPS macromolecular chains, induce higher crystallization, and thus provide higher tensile strength and lower elongation at break. After sandwiching two pieces of poly (butylene adipateco-terephthalate) (PBAT)/peanut shell powder composite thin film to each side of the TPS piece, the PBAT/TPS/PBAT sandwich gains excellent water resistance properties. However, as soon as the sandwich piece is cut into smaller ones, they absorb water quickly, implying such pieces can be biodegraded rapidly. These characteristics make it especially suitable for use in the preparation of cabinet waste bags, which are generally stirred into organic fertilizer with the cabinet waste. Slow degradation may negatively affect soil health and farm production.
The distribution of handshapes in the established lexicon of Israeli Sign Language (ISL)
Authors: Fuks Orit 
Published: August 2021

Abstract
Our study focuses on the perception of the iconicity of handshapes – one of the formational parameters of the sign in signed language. Seventy Hebrew speakers were asked to match handshapes to Hebrew translations of 45 signs (that varied in degree of iconicity), which are specified for one of the handshapes in Israeli Sign Language (ISL). The results show that participants reliably match handshapes to corresponding sign translations for highly iconic signs, but are less accurate for less iconic signs. This demonstrates that there is a notable degree of iconicity in the lexicon of ISL, which is recognizable even to non-signers. The ability of non-signers to detect handshape to form is explained by the fact that word meanings are understood by both deaf and hearing peoples via the mental elaboration of simple iconic sources in which handshape meanings are grounded. The results suggest that while language external iconic mapping could ease the learning of direct iconic forms, it has a more limited capacity to help hearing non-signers learn indirect and opaque forms. The full semiotic distribution of handshapes in the lexicon and their use in language remain difficult for hearing non-signers to understand and depends on more specific language and cultural knowledge.
Dendrite Morphology Minimally Influences the Synaptic Distribution of Excitation and Inhibition in Retinal Direction-Selective Ganglion Cells
Authors: El-Quessny Malak , Feller Marla B. 
Published: August 2021

AbstractThroughout the nervous system, the organization of excitatory and inhibitory synaptic inputs within a neuron’s receptive field shapes its output computation. In some cases, multiple motifs of synaptic organization can contribute to a single computation. Here, we compare two of these mechanisms performed by two morphologically distinct retinal direction-selective ganglion cells (DSGCs): directionally tuned inhibition and spatially offset inhibition. Using drifting stimuli, we found that DSGCs that have asymmetric dendrites exhibited stronger directionally tuned inhibition than symmetric DSGCs. Using stationary stimuli to map receptive fields, we found that DSGCs with both symmetric and asymmetric dendrites exhibited similar spatially offset inhibition. Interestingly, we observed that excitatory and inhibitory synapses for both cell types were locally correlated in strength. This result indicates that in the mouse retina, dendritic morphology influences the amount of tuned inhibition attained through asymmetric wiring but does not dictate the synaptic organization of excitation relative to inhibition.
Estimation of measurement uncertainty in an automated flowmeter calibration system
Authors: Deme Idrissa 
Published: August 2021

The aim of this work is to estimate and analyze the measurement uncertainty in the calibration of liquid flow meters by the gravimetric method, which is a primary method. The calibration system used in this work is the calibration system for liquid flow meters of the National Institute of Metrology Quality and Technology -INMETRO that gives traceability to liquid flow meters in Brazil. The system that was fully operated manually went through an automation process in some of the components. The measurements were made in five ranges for a mass meter and the uncertainty expression followed the procedures of the Guide to the Expression of Uncertainty in Measurement (Iso-Gum). The results were compared with each other and showed the performance of the meters according to the technology used in the measurement and the consistency of the calibration system.

Published: August 2021

OBJECTIVES
Prolonged neonatal seizures are associated with poor neurodevelopmental outcomes. The aim of this quality improvement project was to decrease the time to medical treatment of seizures by 45% within 15 months for neonates admitted to the intensive care nursery (ICN) in an academic children’s hospital.

METHODS
A multidisciplinary team developed key drivers for timely treatment of seizures. Targeted interventions included optimizing a seizure rescue process with a mechanism that brings a pharmacist to the bedside for expedited medication delivery, in addition to interactive educational sessions. The outcome measure was time from the decision to treat seizures to medication administration. The process measure was use of the seizure rescue process with a balancing measure of unnecessary activations of this process. Data were collected from monthly chart review and displayed on statistical process control charts for analysis. The intervention period was from January 2019 to March 2020.

RESULTS
Between January 2016 and March 2020, there were 203 seizure treatment events (160 preintervention and 43 postintervention) in the ICN. Time to treatment of neonatal seizures decreased by 48%, from a baseline of 27 minutes (January 2016 to December 2018) to 14 minutes by March 2020, which reflected significant and sustained improvement. This was associated with improvement in the process metric during the same time periods. Unnecessary seizure rescue process activations were stable postintervention.

CONCLUSIONS
Implementation of an innovative seizure rescue process, in conjunction with staff and provider education, expedited antiseizure therapy in the ICN without requiring code resources.

Published: August 2021

Eimeriosis of farm animals is one of the most widespread parasitic diseases in the world. In the conditions of the steppe zone of Ukraine Eimeria perforans is more common in rabbits and E. arloingi in sheep and goats. Study of factors which influence the development of these protists on the soil surface is one of the major challenges for veterinarians working for large livestock companies and fighting against eimeriosis. Environmental temperature is able to change the speed of sporulation of oocysts Eimeria. Five values of temperature (15, 20, 25, 30, and 35 °C) were used in a laboratory experiment in vitro. At 15 °C, the process of sporulation of E. arloingi and E. perforans in 100% of cases ended on the eighth day. With increase in temperature to 35 °C, the duration of sporulation decreased to three days. When the temperature was 30 °C the completion of sporulation was observed in more than 50% of the oocysts of E. arloingi on the second day, and for E. perforans on the third day. High-speed sporulation at elevated temperatures under conditions of global warming can result in the increasing spread of eimeriosis among wild and domestic animals.

RESUMEN
La vida del escritor costarricense Lisímaco Chavarría (1878-1913) fue corta, compleja, atormentada y ambivalente. Fue admirado y despreciado, premiado y excluido. Su vida estuvo marcada por las carencias materiales y los dramas. Publicó gran parte de su producción literaria en las revistas de la época en la que vivió. Poeta modernista de fama internacional, pero no siempre reconocido por el canon literario de nuestro país. A más de cien años de su muerte, su presencia sigue viva en la memoria colectiva de su natal San Ramón.

Published: August 2021

The fifth chapter of the series about Rudolf Schlechter’s South-American orchids introduces us to those botanists and orchid collectors who travelled and worked in Ecuador and Peru and supplied Schlechter with many of the new orchid species he described. As in previous chapters, the biographies and accomplishments of these travellers are preceded by brief geographical and historical outlines for each of these countries. It is worth mentioning that the lives and orchids of such prominent figures in the orchidology of South America as F.C. Lehmann, W. Hennis, E. Bungeroth and E. Ule, who collected in Ecuador and Peru, have already been mentioned in previous chapters and are therefore omitted here.

The effect of substance P on blood serum glycoproteins under technogenic rotating electric fields in animals with different stress resistance profiles
Authors: Vorontsova T S , Vasileva N N , Isakova L S 
Published: August 2021

Aim. To study the effect of substance P on the blood serum glycoproteins in experimental animals with different stress-resistance profiles under technogenic rotating electric field.
Methods. The level of sialic acids, mucoproteins, fucose, and -L-fucosidase was determined in the blood serum of 72 noninbred white male rats before (control) and on the 10th and 20th day of exposure to a technogenic rotating electric field (REF), as well as under the combination of technogenic rotating electric field and substance P injection at the same time. To determine the stress resistance, the animals were tested using the open field method. Animals were divided into groups based on the tests data obtained: stress-resistant, not stress-resistant and ambivalent.
Results. On the 10th day of technogenic rotating electric field action, the level of sialic acids, fucose, and -L-fucosidase activity increased in all animals. The concentration of mucoproteins tended to decrease. On the 20th day, the sialic acids content remained elevated compared with the control in all groups. The content of mucoproteins decreased in stress-resistant, not stress-resistant and restored to the control level in ambivalent compared with those on the 10th day. On the 20th day, fucose concentration reached control values in stress-resistant and ambivalent animals and decreased in not stress-resistant. On the 10th day of the combined exposure, the concentration of sialic acids, mucoproteins, fucose, -L-fucosidase was reduced in all animals compared with the 10th day of technogenic rotating electric field action. On the 20th day of the combined exposure, the values of the studied parameters remained reduced in all groups of animals compared with those on the 20th day of isolated technogenic rotating electric field action.
Conclusion. The substance P injection limits the effects of technogenic rotating electric field on the metabolism of carbohydrate-containing biopolymers in blood serum in all groups of animals, as can be seen by a decrease in the level of sialic acids, fucose, and low enzymatic activity of -L-fucosidase under combined exposure.

Authors: Gonçalves Villanova Victoria Cristina 
Published: August 2021

Este artigo aponta o início de uma consolidação do conceito Cantovivência e amadurecimento de seus usos. Trata-se de um termo criado durante a escrita monográfica e que vem sendo citado como possibilidade de representação e configuração do que é a interpretação de um corpo negro, nesse caso tendo como análise a interpretação de canções, que em alguns momentos podem ser chamadas de canções de protestos. O objetivo é demonstrar uma luta constante e secular que os povos racializados travam contra a supremacia branca, heteronormativa, racista e sexista. Essa luta é representada por seus corpos negros, afro-diaspóricos, resistentes e artísticos. O estar vivo e o cantar de um corpo negro é político.
