A GERAÇÃO DO PEIXE FRITO E A EFÍGIE DE BELÉM DO PARÁ (OU ACADEMIA RIMA COM BOEMIA, FISIONOMIA E POESIA)
Authors: PEREIRA Carla Soares , SILVA Kátia Regina de Souza da , AMIN Vanda Do Socorro Furtado
Published: July 2019

A presente pesquisa trata da Academia do Peixe Frito (APF), uma geração de poetas, artistas, jornalistas e outros intelectuais paraenses que, nas décadas de 1920 e 30, contribuíram para alavancar as letras amazônidas, fazendo literatura com dificuldade financeira e divulgando o Modernismo no Pará. Esses escritores eram boêmios e suas reuniões, informais que eram, ocorriam principalmente em bares da cidade de Belém. De cunho bibliográfico, esta investigação baseou-se nos escritos de Bolle (2000) acerca da fisionomia da cidade; de Figueiredo (2001), sobre a história literária do Pará; de Larêdo (2012) e Nunes e Costa (2016), a respeito da APF, dentre outros. Este é um texto, portanto, que compila informações sobre os locais de reunião dos membros da APF. A partir dos dados levantados, elaboramos um mapa que pontua os principais locais de encontro do grupo. Defendemos a tese de que a obra desses autores reflete múltiplas imagens da cidade e esta é refletida na vivência dos intelectuais, que, íntimos dela, perscrutam-na nas suas andanças e a enxergam na perspectiva das suas contradições.
ENTRE VIOLAS, PANDEIROS E CUIAS: O QUE CONTAM AS NARRATIVAS ORAIS NO SERTÃO DA BAHIA – A CHULA

Published: July 2019

Uma das formas mais antigas de se conhecer a história é por meio da oralidade, não há povo sem narrativas orais em sua história. Isto posto, e levando-se em conta a sua importância na formação das sociedades, principalmente as narrativas de conhecimento popular, as quais têm se mantido, mesmo no mundo contemporâneo, pretende-se neste artigo refletir acerca da influência das narrativas orais para a difusão de conhecimentos, valores e memórias, a partir do samba de roda da comunidade de Várzea do Poço- BA, em especial o samba chula, propósito de nossa análise. Como não existe a prática de registros escritos das canções compostas pelos sambadores, a chula selecionada, de autoria do Sr. Antônio Xavier, foi obtida por meio de gravação de voz, literalmente transcrita. As discussões e análises permeiam os estudos das Narrativas Orais, do Samba de Roda, da Chula e da Memória, sob o embasamento teórico dos estudos de Bernardes (2017), Doring (2013), Exdell (2017), Lemos (2014), Oliveira (2012), Halbwachs (2006) e Le Goff (1990). Percebeu-se que as narrativas orais representam, como atos de narrar e interpretar, o presente-passado, bem como contribuem na construção de uma identidade, inscrevendo-se no fazer das muitas memórias e das muitas histórias.
Metals phytotoxicity assessment and phyto maximum allowable concentration
Authors: Ryzhenko Nataliia Olexandraivna
Published: July 2019

In this paper, the influence of metals (Cd, Pb, Cu, Co, Ni, Zn) on plants of spring barley (Hordeum vulgare L.) was investigated in polluted sod podzolic sandy loam on layered glacial sands and calcareous deep chernozem on loamy loess soils. We propose to highlight the metals’ phytotoxicity with help of the phyto maximum allowable concentration. The Phyto Maximum Allowable Concentration is a permissible level of metals for plants in polluted soil and represents the safe degree for plants in contaminated ecosystem. The phyto maximum allowable concentration gives the possibility to estimate and to forecast the danger of metals for plants as a biological object that plays a very important role in the life of ecosystem. This approach may be applied for another metals phytotoxicity assessment for other plants.

Relative Average Deviation as Measure of Robustness in the Stochastic Project Scheduling Problem
Authors: Ortiz-Pimiento Néstor Raúl , Díaz-Serna Francisco Javier
Published: July 2019

In the Project Scheduling Problem (PSP), the solution robustness can be understood as the capacity that a baseline has to support the disruptions generated by unplanned events (risks). A robust baseline of the project can be obtained from redundancy based methods, which are considered proactive methods to solve the stochastic project scheduling problem.  In this research, three redundancy based methods are evaluated and their performance is compared in terms of robustness. These methods add extra time to the original activities duration in order to face the eventualities that may appear during the project execution. In this article a new indicator to analyze the solution robustness to the Project Scheduling Problem with random duration of activities is proposed. This indicator called Relative Average Deviation (RAD) is defined as the margin of deviation of the activities’ start times in relation to their durations. The RAD is based in a traditional concept that seeks to minimize the value of the differences between the planned start times and the real executed start times. The planned start times were obtained from the project baseline generated by each redundancy based method and the real executed start times were obtained from a simulation process based on Monte Carlo technique. The new indicator was used to evaluate the robustness of three baselines generated by different methods but applied to the same case study. Finally, the results suggest that the Relative Average Deviation (RAD) facilitates the interpretation of the robustness concept because it focuses on analyzing the deviation margin associated with an activity.

Published: July 2019

No matter how strong the theoretical infrastructure of a study is, if the measurement instruments do not have the necessary psychometric qualities, there will be a question of trust in interpreting the findings, and it will be inevitable to make wrong decisions with the results. One of the important steps in scale development/adaptation studies is to provide evidence of the experimental validity. In order to reveal evidence of construct validity of Likert type scales, to identify factor structures, to confirm previously predicted structures, factor analysis is used. The primary issue to be examined is the level of measurement of the variable and one of the leading decisions that must be taken is which relation matrix will be used. This descriptive research is based on the effects of using Pearson or polychoric correlation matrix in the factor analysis. It is determined that items showed different "item-total correlations", "loading values" and “correlation coefficients”, different factor numbers emerged, different items were removed out of the scale, confirmation status of the structure has changed.

Authors: Yartin Siti , Said Syahrul
Published: July 2019

Patients with end-stage kidney disease (ESRD) undergoing hemodialysis (HD) tend to have multiple comorbidities, especially cardiovascular disease, mineral and bone disorders which are important factors and contribute to the morbidity and mortality of HD patients. So it is important to know the types of intra-dialysis physical exercises that are safe and effective for HD patients. The type of research analyzed in this journal writing is a randomized controlled trial (RCT) that focuses on inter-dialysis physical exercise interventions both at home and HD center. With a literature search using PubMed, ScienceDirect, Willey, Proquest and Google Scholar databases. And those who meet the relevant requirements and reviews are: 8. Based on several reviews of intradialytic exercise studies in HD patients, intra-dialysis low intensity strength training is found safe and effective in adults and older. Research shows that doing 30 minutes of intradialytic exercise per session 3 times a week for at least ≥8 weeks is beneficial for HD patients. Regular exercise should be considered as an important therapeutic modality in the care of patients undergoing HD. Strength training improves physical performance, nutritional status and physical activity. But this study needs further research, so that it can contribute to the provision of evidence-based information in applying safe intradialytic exercises and become part of routine dialysis treatment units

Published: July 2019

Stunting (short body) is a very short body state that goes beyond 2 SD below the median length or height of the population body which is an international reference. Stunting describes a lack of nutrition that has been going on for a long time and requires time for children to develop and recover. A number of studies show a link between Stunting with poor motor and mental development in early childhood, and poor cognitive achievement and school achievement in late childhood. In Sleman Regency in 2014 the Stunting number reached 12.87% (DIY 14.32%), wasting 4.02% (DIY 3.89%) and overweight 5.82% (DIY 5.84%). The highest Stunting rate appears in the Margins of 141 toddlers experiencing Stunting. Of all the toddlers in existence, and as a cause of malnutrition cases are the presence of comorbidities, congenital abnormalities from birth and because of wrong care. Parents of children with Stunting have focused on treatments to restore anthropometric growth but are less aware of the stimulation efforts that need to be done. The purpose of this study was to provide a design intervention in midwifery care in children with Stunting by providing education to parents about the stimulation of growth and development. The research method uses quasi-experimental pre-post test with control group design. Data analysis was carried out by Paired T-Test analysis. Respondents in this study were mothers with 1-3 year old stunting children in Sleman Regency. The sampling technique used in this study was using purposive sampling technique. The number of samples in this study was 37 people. The results showed that there was an effect of providing education on the stimulation of child growth and development of parents' children with Stunting with a significance value of p = 0.002 (p <0.05). There is are the influence of education giving on the parent's behavior about growth stimulation in children with stunting.

Environmental quality cultivation of considerable influence against the survival and growth of living beings in the water. Improvements to the environmental conditions of cultivation in order to remain stable and optimal for aquatic organisms, including fish as aquaculture animals become very necessary one, namely the granting of Ca(OH)2 (calcium hydroxide) and NaHCO3 (sodium bicarbonate). The application of Ca(OH)2 and NaHCO3 in fish farming serves as the buffer pH of pond water. In addition, the application of both these materials also function as degradation organic matter chemically, control the ratio N/P and the abundance of plankton in the water. This research aims to know the dynamics of the pH value, COD, N/P ratio and abundance of plankton by administering calcium hydroxide (Ca(OH)2) and sodium bicarbonate (NaHCO3) in the water. Methodology this research uses descriptive survey method or a method of research that aimed to describe existing phenomena, which takes place at the moment or the past. The results of the measurement of the pH value before the grant of Ca(OH)2 and NaHCO3 that is of 6.6-6.8 whereas after the grant of Ca(OH)2 and NaHCO3, there is increased and decreased range between 6.8-7.4. The results of the measurement of the value of COD prior to the grant of Ca(OH)2 and NaHCO3 that is ranged between 72.5-32.5 mg/l while the after grant of Ca(OH)2 and NaHCO3, there is increased and decreased ranged between 26-55 mg/l, results of measurement of the value of the ratio N/P before the grant of  Ca(OH)2 and NaHCO3 on all points of observation that is ranged between 3.15 – 3.68 while following the grant of Ca(OH)2 and NaHCO3, there is a decrease and an increase in the value of the ratio N/P a row ranges between 1.67 – 1.8 and 13.8 – 15.18. Observations a total density of plankton showed before the grant of Ca(OH)2 and NaHCO3 that is in the range 206.250-1.103.125 x104 ind/l whereas after the grant of Ca(OH)2 and there is a decrease in the density of NaHCO3 total plankton reach 9.375x104 ind/l. Research has been done gives the conclusion that the grant of Ca(OH)2 and NaHCO3 pH value can increase and may decrease the value of the COD. the ratio N/P and a density of total plankton.

The Unification of Gravity and Quantum Physics Due to the Isospin of Dirac Particles
Authors: Roza Engel
Published: July 2019

It is shown that gravity and quantum physics can be unified upon the basis of a quark description in terms of a gravitational Dirac particle. It requires the awareness of a second elementary dipole moment (isospin) next to the angular moment (spin) of Dirac particles and the awareness of an (unbroken) omnipresent energetic cosmological background field. The unification has been made explicit by an expression that relates the two major gravitational constants of nature (the gravitational constant and Milgrom’s acceleration constant) with the two major nuclear constants of nature (the weak interaction boson and the Higgs boson).
Meta-Analysis of Cancer Triploidy: Whole-Genome Rearrangements in Male Human Tumours Are Characterised by XXY Karyotypes
Authors: Vainshelbaum Ninel M. , Zayakin Pawel , Kleina Regina , Giuliani Alessandro , Erenpreisa Jekaterina
Published: July 2019

Triploidy in cancer is associated with poor prognosis but its origins remain unclear. Here, we attempted to differentiate between random chromosomal and whole-genome origins of cancer triploidy. In silico meta-analysis was performed on 15 male malignant and 5 benign tumour cohorts (2928 karyotypes) extracted from the Mitelman Database, comparing their ploidy and combinations of sex chromosomes. A distinct near-triploid fraction was observed in all malignant tumour types, being especially high in seminoma. For all tumour types, X-chromosome doubling, predominantly observed as XXY, correlated strongly with the near-triploid state (r≈0.9, p<0.001), negatively correlated with near-diploidy, and did not correlate with near-tetraploidy. A smaller near-triploid component with a doubled X-chromosome was also present in 3 of 5 benign tumour types, especially notable in colon adenoma. Principal Component Analysis revealed a non-random correlation structure shaping the X-chromosome disomy distribution across all tumour types. We suggest that doubling of the maternal genome followed by pedogamic fusion with a paternal genome (a possible mimic of the fertilization aberration, 69, XXY digyny) associated with meiotic reprogramming may be responsible for the observed rearrangements of genome complements leading to cancer triploidy. The relatively frequent loss of the Y-chromosome results secondary from chromosome instability.

Published: July 2019

In order to achieve better knowledge of the thermal barrier coatings (TBCs) by supersonic atmospheric plasma spraying (SAPS) process, an experimental study was carried out to elaborate physicochemical properties of particles in-flight during the SAPS process. One type of commercially available agglomerated and sintered yttria-stabilized-zirconia (YSZ) powders were injected into the SAPS plasma jet and collected by shock chilling method. The YSZ particles in-flight physicochemical properties of the melting state, morphology, microstructure, particle size distribution, element composition changes and phase transformation during the SAPS process have been systematically analyzed. The melting state, morphology and microstructure of the collected particles were determined by scanning electron microscopy (SEM). The particle size distribution was measured by a laser particle size analyzer (LPSA). Element compositions were quantitatively analysed by an electron probe X-ray microanalyzer (EPMA). Additionally, the X-ray diffraction (XRD) method was used to analyse the phase transformation. The results showed that the original YSZ powders injected into the SAPS plasma jet were quickly heated and melted from the outer layer companied with breakup and collision-coalescence. The outer layer of the collected particles containing roughly hexagonal shaped grains exhibited a surface texture with high sphericity and the inside was dense with hollow structure. The median particle size was decreased from 45.65 μm to 42.04 μm. Besides, phase transformation took place and the content of zirconium (Zr) and yttrium (Y) element was decreased with the evaporation of ZrO2 and Y2O3.

Published: July 2019

This paper is devoted to investigate charged vector particles tunneling via horizons of a pair of accelerating rotating charged NUT black hole under the influence of quantum gravitational effects. For this purpose, we use the modified Proca equation incorporating generalized uncertainty principle. Using the WKB approximation to the field equation, we obtain a modified tunneling rate and the corresponding corrected Hawking temperature for this black hole. Moreover, we analyze the graphical behavior of corrected Hawking temperature T'H with respect to the event horizon for the given black hole. By considering quantum gravitational effects on Hawking temperatures, we discuss the stability analysis of this black hole. For a pair of black holes, the temperature T'H increases with the increase in rotation parameters α and w, correction parameter β, black hole acceleration α and arbitrary parameter k and decreases with the increase in electric e and magnetic charges g.

Bioactive peptides are related to the prevention and treatment of many diseases. GPETAFLR is an octapeptide which was isolated from lupine (Lupinus angustifolius L.) and showed anti-inflammatory properties. The aim of this study was to evaluate the potential activity of GPETAFLR to prevent non-alcoholic fatty liver disease (NAFLD) in high-fat diet (HFD)-induced obese mice. C57BL/6J mice were fed a standard diet or an HFD. Two of the groups fed the HFD diet were treated with GPETAFLR in their drinking water at 0,5 mg/kg/d or 1 mg/kg/d. To determine the ability of GPETAFLR to improve the onset and progression of NAFLD, histological studies, hepatic enzyme profile, inflammatory cytokine and lipid metabolism-related genes and proteins were analyzed. Our results suggest that HFD-induced inflammatory metabolic disorders were alleviated by treatment with GPETAFLR. In conclusion, dietary lupine consumption could repair HFD-induced hepatic damage, possibly via modifications in the liver’s lipid signalling pathways.
Elliptical Tracks: Evidence for Superluminal Electrons?
Authors: Fredericks Keith
Published: July 2019

In the literature of Low-Energy Nuclear Reactions (LENR), particle tracks in photographic emulsions (and other materials) associated with certain electrical discharges have been reported. Some Russian and French researchers have considered these particles to be magnetic monopoles. These tracks correspond directly to tracks created with a simple uniform exposure to photons without an electrical discharge source. This simpler method of producing tracks supports a comprehensive exploration of particle track properties. Out of 750 exposures with this method, elliptical particle tracks were detected, 22 of which were compared to Bohr-Sommerfeld electron orbits. Ellipses fitted to the tracks were found to have quantized semi-major axis sizes with ratios of ≈n2/α2 to corresponding Bohr-Sommerfeld hydrogen ellipses. This prompts inquiry relevant to magnetic monopoles due to the n2/α2 force difference between magnetic charge and electric charge using the Schwinger quantization condition. A model using analogy with the electron indicates that the elliptical tracks could be created by a bound magnetically charged particle with mass mm = 1.45 × 10-3 eV/c2, yet with superluminal velocities. Using a modified extended relativity model, mm becomes the relativistic mass of a superluminal electron, with m0 = 5.11 × 10-3 eV/c2, the fine structure constant becomes a mass ratio and charge quantization is the result of two states of the electron.

Objectives. Sound field (SF) audiometry tests are usually conducted in audiometric booths measuring greater than 2×2 m in size. However, most private ENT clinics carry about 1×1-m-sized audiometric booths, making SF audiometry testing difficult to perform. The aims of this study were to develop an SF audiometry system for use in smaller audiometric booths and compare its performance with traditional system.Methods. The newly developed SF audiometry system can yield an SF signal at a distance of about 30 cm from the subject’s ears. Its height can be adjusted according to the subject’s head height. We compared SF hearing results between the new SF system and the traditional SF audiometry system in 20 adults with normal hearing (40 ears) and 24 adults with impaired hearing levels (38 ears) who wore hearing aids. Comparative parameters included warble tone audiometry threshold, a speech reception threshold (SRT), and a speech discrimination score (SDS). For statistical analysis, paired t-test was used. The equivalence of both SF systems was tested using two one-sided test (TOST) with a margin of 5 dB (normal hearing participants) and 10 dB (hearing aids wearing participants).Results. Among participants with normal hearing, warble tone hearing thresholds of 0.5, 1, 2, and 4 kHz, average values of these four frequencies, and SRT were similar between the two systems (all P>0.05). Participants with hearing aids showed similar warble tone threshold and SRT (P>0.05) in both systems except for threshold of 4 kHz (P=0.033). SDS was significantly higher in the newly developed system (P<0.05). TOST results showed equivalent SF audiometry results using either system.Conclusion. Audiometric results of the newly developed SF audiometry system were equivalent to those of a traditional system. Therefore, the small SF audiometry system can be used at small audiometric booths present in most private ENT clinics.

Published: July 2019

Background: Moderate and deep sedation are well-established techniques in many developed countries, and several guidelines have been published. However, they have received attention in China only in recent years. The aim of this study is to investigate current paediatric sedation practices in tertiary children’s hospitals and tertiary maternity and children hospitals in China.
Methods: All tertiary children’s hospitals and tertiary maternity and children hospitals registered with the National Health Commission of the People’s Republic of China were invited to participate in an electronic survey, which included information on the sedation caseload, facility availability, staff structure, clinical-skill requirements for sedation providers, fasting guidelines, patient-monitoring practices, and choice of sedatives.
Results: Fifty-eight of the 63 hospitals that completed the survey (92.1%) provided moderate and deep sedation. Dedicated sedation rooms and post-sedation recovery rooms were found in only 14 (24.1%) and 19 (32.8%) hospitals, respectively. Sedation for non-invasive procedures was primarily performed by anaesthesiologists (69.0%); however, 75.9% of the sedation providers had not received paediatric basic and advanced life-support training. Children were asked to fast from clear liquids for at least 2 h in 44.8% of hospitals and at most 6 h in 5.2% of hospitals; they were asked to fast from solid food/milk for at least 4 h in 27.6% of hospitals and more than 8 h in 1.7% of hospitals. The most commonly used sedative in all groups was chloral hydrate. For rescue, propofol was the most widely used sedative, particularly for children older than 4 years.
Conclusion: Moderate and deep sedation practices vary widely in tertiary children’s hospitals and tertiary maternity and children hospitals in China. More optimized practices should be established to improve the quality of moderate and deep sedation.

Background:
Prevalence and impact of chronic rhinosinusitis (CRS) in chronic obstructive pulmonary disease (COPD) remain unclear. We hypothesized that CRS is more frequent in patients with COPD compared to controls and we aimed to evaluate the odds of CRS in both groups.
Methods:
We recruited patients with COPD and a healthy control group in a tertiary referral hospital in Switzerland. Diagnosis of CRS was defined according to published guidelines and supported by computed tomography (CT) findings. Sino-nasal-outcome-test-20 (SNOT-20) and sino-nasal-outcome-test-primary-nasal-symptom-score (SNOT-PNS-score) were self-assessed with a cut-off for abnormality of >12.
Results:
Data from 83 COPD patients (35 females, age: 67 years ± 10) and 34 controls (18 females, age: 67 years ± 12) were analyzed. In the COPD group 14 out of 83 (20.3%) fulfilled the diagnosis of CRS compared to only 1 out of 34 (3%) in the control group (OR 6.7; 95% CI 0.84-53.10; p = 0.064). Forty-eight COPD patients (59%) and 14 controls (41%) had an abnormal SNOT-20 score (OR 1.96; 95% CI 0.87-4.40; p=0.10), with a median score of 16.0 (ICR 21) in COPD patients compared to a median score of 8.0 (ICR 13) in controls (p=0.001). The SNOT-PNS-score was abnormal in 49 COPD patients (59%) and in 9 controls (26%) (OR 4.00; 95% CI 1.66-9.64; p=0.001). Abnormal findings of the upper airways did not correlate with COPD severity or smoking status.
Conclusions:
CRS was a frequent diagnosis in patients with COPD. CRS reduces quality of life in this patient group.

Background

Initial periodontal therapy (IPT) is cornerstone of periodontal therapy and the first step to control of periodontal risk factors. Scaling and root planing are used to treat root surface irregularities and remove virulent factors caused by periodontal pathogens. This procedure also incorporated into periodontal surgery. To elucidate the effects of IPT on prevalence of Epstein-Barr virus (EBV) DNA and Porphyromonas gingivalis, we used subgingival plaque samples from chronic periodontitis (CP) patients.

Methods

Seventeen CP patients were recruited and measured periodontal clinical parameters such as probing pocket depth (PD) and bleeding on probing (BOP), and subgingival plaque samples were collected from two periodontal sites with PD of <3 mm (healthy sites: HS) or >5 mm (periodontitis sites: PS) at first visit and after IPT. Plaque samples were subjected to a real-time PCR to detect EBV DNA and P. gingivalis.

Results

EBV DNA and P. gingivalis were detected 9 (52.9%) and 14 (82.3%) in the subgingival samples from HS, and 13 (76.5%) and 14 (82.3%) in the PS at first visit. After IPT, number of detections of EBV DNA and P. gingivalis were decreased to 5 (29.4%) and 13 (76.5%) in the HS, and 9 (52.9%) and 10 (58.8%) in the PS. Significant improvements in PD and BOP were observed after IPT in PS. Coexistence of EBV DNA and P. gingivalis in the subgingival samples from PS at first visit (12; 70.6%) were significantly decreased after IPT (6; 35.3%).

Conclusion

These results suggest that the IPT was effective in improvement of clinical parameters such as PD and BOP and reducing the coexistence of EBV and P. gingivalis in the subgingival plaque from PS. However, IPT could not eradicate the EBV and P. gingivalis. Further research would be necessary for improving the periodontal treatment strategy.
