Authors: Bispo Santos Marla , Santos Paulo Roberto Alves dos
Published: September 2022

O presente estudo tem como corpus o romance Maréia, de Miriam Alves, cuja trama se desenvolve a partir de pontes que conduzem aos campos da memória e da (re)construção identitária. A partir do protagonismo feminino negro, a narrativa alinha atemporalidades, discute as representações históricas negro diaspóricas e colonial, além de evidenciar as relações das personagens com práticas religiosas que remetem a ancestralidades. Nesse sentido, o objetivo desse trabalho é o de caracterizar aspectos identitários, em Maréia, pela perspectiva da autoria feminina negra. O referencial teórico tem fundamentação em Cuti (2010), com o conceito de literatura negro-brasileira; Conceição Evaristo (2011), para as reflexões sobre autoria feminina negra; Candau (2013, 2019) e Le Goff (1990), a respeito da memória e identidade; Silva, Hall e Woodward (2020), para tratar da identidade e representação, dentre outros.

Authors: Azevedo Renan Ramires de , Batistote Maria Luceli Faria
Published: September 2022

A semiótica discursiva, de Greimas, hodiernamente, toma não somente o texto verbal como objeto de análise, mas textos com formas outras de expressão. Nesse sentido, o presente trabalho tem intuito de realizar uma análise, sob o viés semiótico, do monumento “Cavaleiro Guaicuru”, produzido pelo artista plástico Anor Mendes, escultor sul-mato-grossense. A estátua está localizada no Parque das Nações Indígenas, na cidade de Campo Grande – MS, e é relevante foco turístico da capital do estado. Para tanto, utilizamo-nos dos postulados de Diana Luz Pessoa de Barros (2005, 2019) e de José Luiz Fiorin (2000, 2011) no que concerne à análise no âmbito da teoria da semiótica padrão; e dos preceitos de Antonio Vicente Pietroforte (2007, 2018) sobre a análise do plano da expressão do texto plástico. Ademais, realizamos, ainda, algumas considerações sobre o papel social da escultura a partir da noção de valor prevista por Jean-Marie Floch (1995). Dessa forma, foi possível concluir, por meio das análises, efeitos de sentidos que tornam perceptível seu importante papel social na região por possuir, em seu conteúdo e expressão, traços históricos e da identidade sul-mato-grossense.

Authors: Gouiaa Raef , Issa Elias
Published: September 2022

Since the 2008 financial crisis, the relationship between investing in enterprise risk management (ERM) and its influence on business performance has continued to gain popularity and with the enormous volatility in the business world today, proper ERM is more important than ever (Chen, Tsao, Hsieh, & Hu, 2019; Maruhun, Atan, Yusuf, Rahman, & Abdullah, 2021). Is it the companies that manage risks better that perform better, regardless of the industry? The objective of this research is to analyze the effect of the way in which risks are managed by Canadian firms in different industries and the impact of this management on different levels of performance. A sample of 30 annual reports covering the fiscal years ending in 2019 and 2020 from fifteen Canadian companies that trade on the Toronto Stock Exchange (TSX) has been completed. The analysis of Pearson’s correlation coefficients as well as the coefficients of determinations made it possible to assess the relationship between the various ERM variables and company performance. By analyzing the correlations obtained for the 2019 and 2020 financial years, no significant relationship could be demonstrated between ERM, and 5 performance indicators analyzed. However, several significant correlations have indeed been demonstrated between each industry studied, these affecting different performance indicators depending on the sector.
Prediction of the Charge Transport and Electronic Properties of Two Pyrazole Derivatives in terms of Their Solid Molecular Arrangements and Reorganization Energy: The Effects of Nitro Groups on Structure-Property Relationship
Authors: Biçer Abdullah , Cin Günseli , Yakalı Gül
Published: September 2022

Pyrazole derivatives have noteworthy attention in optoelectronic field
since they demonstrate distinctive properties in semiconducting devices
such as organic light emitting diodes (OLEDs), nonlinear optical (NLO)
and solar cells. organic field effect transistors (OFETs). Therefore, to
establish the relationship between the structure and property of the
molecules, we explored influence of nitro groups on the 3D molecular
structures, reorganization energy, absorption spectra, frontier
orbitals, ionization potential (IP), electronic affinity (EA),
intra-molecular charge transfer (ICT) and charge transport behaviour of
the two π-conjugated pyrazole compunds through single crystal x-ray
crystallographic and quantum chemical calculations by considering Marcus
Electron Transfer Theory and Density Functional Theory. Our experimental
and theoretical results predicted that incorporation of the nitro groups
to the molecule skeleton increased the rigidity of the conjugated system
and improve the efficient charge injection in electronic devices by
lowering the hole (λ_h) and electron (λ_e) reorganization energy from
0.48eV to 0.34 eV, 0.44 eV to 0.26 eV, respectively which can be
effective way to design molecules with desired electronic properties via
smart chemical structural modification. In addition, both molecules
aggregate with the close preferred π⋯π stacking interactions (J and
antiparallel H type) and multiple intermolecular interactions in their
solid phases. Accordingly, both molecules are suggested to be quite
suitable for p-type semiconducting materials with small reorganization
energy and preferred stacking modes in solid phase. In addition, this
study paves the way for the design and synthesis of new conjugated
pyrazole molecules for high device performance.

Authors: Liu Huazhen , Pope Micah , Doehring Todd , Kachroo Pradeep , Hildebrand David
Published: September 2022

Previous reports indicate variable soybean quality parameters
exported/shipped from different geographic regions. This review compares
the quality of soybeans grown under diverse environmental conditions
from the three main exporting countries. Soybeans from the US and Brazil
have similar levels of protein but the US soybeans have higher foreign
material and lower heat damage or total damage than soybeans from
Brazil. US and Brazil meal have higher crude protein than meal from
Argentina. At equal crude protein content, US meals had less fiber, more
sucrose and lysine and better protein quality than South American meals.
Methionine, threonine, and cysteine levels were similar in soybean
protein from US and Argentina and higher than that in soybean protein
from Brazil. Degummed soybean oil from Brazil had higher free fatty
acids, neutral oil loss, phosphorus, calcium and magnesium than degummed
oil from the US or Argentina. The information available suggests that
environmental conditions under which soybeans are grown and stored as
well as handling can have a large impact on chemical composition and
nutrient quality of soybean oil.

Objective: To evaluate the association between COVID-19 infection and severity of infection on longer-term glycemic control and weight in persons with type 2 diabetes mellitus (T2D) in the U.S.

Research Design and Methods: We conducted a retrospective cohort study using longitudinal electronic health record data of patients with COVID-19 infection from the National COVID Cohort Collaborative (N3C). Patients were ≥18 years old with an ICD-10 diagnosis of T2D and at least 1 HbA1c and weight measurement prior to and after an index date of their first COVID-19 diagnosis or negative SARS-CoV-2 test. We used propensity scores to identify a matched cohort balanced on demographic characteristics, comorbidities, and medications used to treat diabetes. The primary outcome was the post-index average hemoglobin A1c (HbA1c) and post-index average weight over a 1-year time period beginning 90 days after the index date among patients who did and did not have COVID-19 infection. Secondary outcomes were post-index average HbA1c and weight in patients who required hospitalization or mechanical ventilation.

Results: There was no significant difference in the post-index average HbA1c or weight in patients who had COVID-19 infection compared to controls. Mechanical ventilation was associated with a decrease in average HbA1c after COVID-19 infection.

Conclusions: In a multicenter cohort of patients in the U.S. with pre-existing T2D, there was no significant change in longer-term average HbA1c or weight among patients who had COVID-19 infection. For patients with COVID-19 infection, mechanical ventilation was associated with a decrease in HbA1c after infection.
The Properties of Biomaterials Hidden in the Spaces of Higher Dimension
Authors: Zhizhin Gennadiy
Published: September 2022

The influence of the higher dimension of biomolecules on processes in biomaterials is investigated. It has been proved that the optical activity of organic compounds is a consequence of the higher dimensionality of molecules in solution, and not a consequence of the three-dimensional shape of solid crystals, as Pasteur suggested. It is shown that glucose and ribose molecules have dimensions of 15 and 12, respectively. Helical chains of glucose molecules are characterized by the rotation of molecules in perpendicular planes in the opposite directions. A hidden order of interaction of nucleic acids in a space of higher dimension was discovered, leading to a one-to-one correspondence between the number of pair of bound nitrogenous based and the number of amino acids.

Authors: Shete H.V. , Sohani M.S.
Published: September 2022

Data regarding the influence of high-pressure coolant on the performance of drilling process using design of experiment has been limitedly available. This paper presents the effect of higher coolant pressures along with spindle speed, feed rate and peck depth on the surface roughness of hole using Taguchi technique. Experimental set up was developed consisting of specially manufactured high-pressure coolant system and high-pressure adapter assembly attached to vertical machining center. Developed experimental set up has optimized utilization of non-through coolant vertical machining center in a small-scale industry. Experiments were conducted on AISI 1055 steel with TiAIN coated drill on the vertical machining center. Taguchi technique was used for design of experiment and analysis of results. Results revealed that the surface roughness improve till coolant pressure reaches to an optimum value of 13.5 bar and there after it decreases. Coolant pressure and spindle speed was the significant process parameters for the hole surface roughness. Surface roughness at the top of hole was considerably lower than the bottom of hole, under the action of all process parameters. Supply of coolant at high pressure has resulted in lower surface roughness even with large peck depth; which indicate that, manufacturing cost can be reduced with the use of high-pressure coolant in drilling.

Authors: Collini Valentino , Imazio Massimo , De Biasio Marzia , Sinagra Gianfranco
Published: September 2022

Aims

Vaccination represents a cornerstone of prevention in the COVID-19 pandemic. Rare adverse events including acute pericarditis and myopericarditis have been reported.

Methods

All consecutive patients referred to our referral center for pericardial diseases following COVID-19 vaccination from 1 April 2021 to 15 April 2022 were included. Acute pericarditis and myopericarditis were diagnosed according to ESC guidelines. Patients with SARS-CoV-2 infection were excluded from the study.

Results

Twenty-four patients (79% men) aged 39.7 ± 19.8 years were referred to our center with pericarditis after receiving COVID-19 vaccination. Thirteen (54%) patients were diagnosed with myopericarditis. The mean time between vaccination and symptoms onset was 7.0 ± 4.9 days, and the most frequent symptom was pericarditic chest pain (83%). Respectively, 50 and 33% of patients presented after the second and the third dose of the vaccine. Almost all patients were treated with both nonsteroidal anti-inflammatory drugs and colchicine. Five patients (21%) experienced a recurrence of pericarditis. No patient died or developed constrictive pericarditis. Mean follow-up was 8.0 ± 3.2 months.

Conclusion

COVID-19 vaccine-related pericarditis typically manifest with mild clinical signs, in young male individuals, a few days after the second or third vaccine dose and are commonly characterized by a rapid complete recovery.

Introduction

Cardiac tumors are rare and heterogeneous entities which still remain a diagnostic and therapeutic challenge. The treatment for most cardiac tumors is prompt surgical resection. We sought to provide an overview of surgical results from a series of consecutive patients treated at our tertiary care center during almost a 20-year experience.

Methods and Results

In this single center study, 55 consecutive patients with diagnosis of cardiac tumor underwent surgical treatment from January 2002 to April 2021. Of these, 23 (42%) were male and the mean age was 62 ± 12 years. Fifteen (27%) patients were symptomatic at the time of the diagnosis, mostly for dyspnea and palpitations. The most frequent benign cardiac tumor was myxoma (32; 58%), occurring mainly in the left atrium (31; 97%). Pleomorphic sarcoma was the most frequent primary malignant cardiac tumor (4; 7%), mainly located in the ventricles (1; 25% in the left ventricle; 2; 50% in the right ventricle). In all cases of benign tumors surgery was successful with no relapses. Two (50%) pleomorphic sarcomas showed subsequent relapses. After a median follow-up of 44 months, 15 (27%) patients died. Although malignant tumors presented a limited survival, benign tumors showed a very good prognosis.

Conclusion

Cardiac tumors require a multidisciplinary approach to guarantee a prompt diagnosis and appropriate treatment. In our surgical experience, outcome after surgery of benign tumors was excellent, while malignant tumors had poor prognosis despite radical surgery.
The value of air purification and carbon storage ecosystem services of park trees in Warsaw, Poland
Authors: Szkop Zbigniew
Published: September 2022

This study assessed, in monetary terms, the ecosystem services provided by trees growing in public parks and garden squares in Warsaw, Poland. It focused on the valuation of two services: air purification (measured as an annual benefit stream in EUR/year) and carbon storage (measured as a fixed value at a given point in time in EUR). The study was conducted using the Avoided Cost Method with i-Tree Eco software. The initial calculations were based on data obtained from 41 selected green spaces in Warsaw. Subsequently, the results were extrapolated to all public parks and garden squares. The findings indicate that the average economic value of the NO2, SO2 and PM2.5 pollution removal ecosystem service provided by trees in Warsaw is around 3 EUR/tree/year. On average, one hectare of a public park in Warsaw provides this service at a value of 408 EUR/ha/year, while one hectare of a garden square provides this service at a value of 347 EUR/ha/year. With regards to the carbon storage ecosystem service, the results showed that the average economic value of this service is around 170 EUR/tree. On average, one hectare of a public park provides this service at a value of 22.4 thousand EUR/ha, and one hectare of a garden square provides this service at an average value of 18.9 thousand EUR/ha. By extrapolating these results, the total value of the air pollution removal ecosystem service provided by trees growing in all public parks and garden squares in Warsaw was estimated to range from 393 to 560 thousand EUR/year. The value of the carbon storage service ranges from 23.3 to 30.2 million EUR.

Published: September 2022

Starting December 2019, in China, the SARS-CoV-2 infection became a local health issue, but its high infectiveness quickly turned it into a pandemic, to be declared an epidemiological emergency of international concern less than two months from identifying the first cases. Despite tremendous efforts aimed at discovering new drug classes that would slow down or stop the evolution of the COVID-19 disease and curb the number of severe cases and related complications, there is no specific antiviral treatment to date. The only efficient measure proved to be the prophylaxis, through vaccination.
Therapeutic challenges in a case of sarcoidosis
Authors: Hédi-Katalin Sárközi , Vultur Mara Andreea , Szathmáry Mioara , Budin Corina , Chiș Monica , Jimborean Gabriela
Published: September 2022

Sarcoidosis is a chronic systemic inflammatory disease with unknown etiology, whose diagnosis is based on suggestive symptoms/imaging, histopathological examination with non-caseous granuloma, and exclusion of other etiologies. Corticosteroid therapy is the treatment of choice for moderate/severe forms, but medication intolerance or unfavorable evolution may require immunomodulatory therapy. A 40-year-old patient known with poly-allergy was hospitalized for resting dyspnoea, dry cough, night sweats, and itching. Objective examination identifies roughened breathing, wheezing and SpO2 = 98%. Spirometry shows a medium mixed ventilatory dysfunction. Computed tomography (CT) describes multiple mediastinal lymphadenopathies and inhomogeneous hepatomegaly. Osteomedullary biopsy refutes the suspicion of lymphoma. Bronchoscopy detects bronchial hypervascularization. Due to the suggestive imaging context, a transbronchial biopsy was performed (EBUS-TBNA) from the mediastinal lymphadenopathy. Histopathological examination suggested sarcoidosis: granulomas with epithelioid histiocytes, without caseous necrosis, associated with Langerhans cells and lymphocytes. We initiated corticosteroid therapy, but the patient had an allergic reaction that required the interruption of treatment and administration of methotrexate. After eight months, the clinical and imaging aspect worsened, and we replaced the treatment with cyclophosphamide. However, side effects occurred after a few months, it was replaced with azathioprine. The patient’s condition deteriorates significantly with desaturation. We requested a consultation with the ‘Sarcoidosis Center’ in Rotterdam, which recommended treatment with anti-TNF-α or human immunoglobulin. The patient shows a slightly favorable evolution under human immunoglobulin. The poly-allergy and drug intolerance, including corticosteroid therapy, led to the initiation of immunomodulatory therapy for a young patient with moderate/severe sarcoidosis. The choice of medication was difficult due to the side effects.

Burung memiliki daya tarik yaitu memiliki warna unik dan suara merdu, termasuk jenis burung perkutut (Geopelia striata). Tingginya nilai ekonomi burung perkutut (G. striata) bagi masyarakat menyebabkan perburuan dan perdagangan satwa tersebut dilakukan secara berlebihan sehingga dapat menurunkan populasi burung di alam. Usaha konservasi yang dilakukan untuk mencegah terjadinya penurunan populasi burung di alam yaitu tempat penangkaran burung. Kontaminasi bakteri merupakan kendala selama proses perkembangbiakan burung. Tujuan dilakukan penelitian ini adalah untuk menentukan Angka Lempeng Total (ALT) bakteri dan Escherichia coli pada sampel isi dan cangkang telur burung perkutut (G. striata) yang gagal menetas dari beberapa penangkar burung lokal Denpasar, Bali. Penelitian dilakukan di Laboratorium Mikrobiologi Program Studi Biologi FMIPA Universitas Udayana. Metode yang digunakan yaitu uji ALT secara pour plate pada media Nutrient Agar (NA) dan Eosin Methylene Blue Agar (EMBA). Hasil pengujian ALT bakteri pada sampel isi dan cangkang telur diperoleh rata – rata tertinggi terdapat di penangkar III, sedangkan terendah di penangkar I. Hasil pengujian ALT Escherichia coli pada sampel isi dan cangkang telur diperoleh rata – rata  tertinggi terdapat di penangkar III. Keberadaan jumlah ALT bakteri dan Escherichia coli pada sampel isi dan cangkang telur burung perkutut (G. striata) bervariasi pada setiap penangkar.

Latar Belakang: Karakteristik pasien COVID-19 diperlukan dalam pengendalian pandemi COVID-19. Beragamnya gejala klinis yang muncul, mulai dari asimtomatik sampai kritis menyebabkan perbedaan dalam diagnosis, isolasi, dan pengobatan pasien. Pasien asimtomatik dapat bertindak sebagai karier yang menyebarkan virus kepada orang lain. Pasien simtomatik dengan gejala ringan sampai berat memerlukan intervensi dan pengobatan yang berbeda untuk mencegah penularan dan perburukan klinis. Perbedaan intervensi juga perlu mempertimbangkan durasi konversi negatif yang berkaitan dengan risiko penularan dan peningkatan kasus COVID-19.
Objektif: Tinjauan literatur ini bertujuan untuk memberikan gambaran karakteristik pasien COVID-19 simtomatik dan asimtomatik di rumah sakit.
Metode: Pencarian artikel penelitian bersumber dari database PUBMED dan ScienceDirect, yang melalui proses penyaringan dan analisis data.
Hasil: Tinjauan ini dilakukan terhadap 13 artikel penelitian yang terdiri dari: 3 artikel meneliti pasien simtomatik, 4 artikel meneliti pasien asimtomatik, 6 artikel meneliti pasien simtomatik dan asimtomatik. Prevalensi pasien COVID-19 simtomatik di rumah sakit lebih banyak dibandingkan pasien asimtomatik. Pasien simtomatik lebih banyak ditemukan pada kelompok usia yang lebih tua dibandingkan pasien asimtomatik. Pasien simtomatik memiliki median usia berkisar antara 22-69 tahun, sedangkan pasien asimtomatik berkisar antara 19-37 tahun. Sebagian besar studi menemukan dominasi laki-laki pada kelompok pasien simtomatik, dan perempuan pada kelompok pasien asimtomatik. Durasi konversi negatif hasil pemeriksaan RT-PCR pada pasien simtomatik dan asimtomatik dari tinjuan ini tidak ditemukan perbedaan signifikan.
Kesimpulan: Durasi konversi negatif dalam penentuan bebas isolasi pasien COVID-19 perlu mempertimbangkan durasi sejak awal terkonfirmasi positif pada pasien asimtomatik, pertimbangan perbaikan gejala klinis dan pemeriksaan penunjang pada pasien simtomatik.

Aim: The aim of this study was to evaluate families’ perceptions regarding nursing care provided to patients in intensive care units (ICUs) at a district hospital in Iran.
Methods: A non-randomised controlled trial was done in the ICU of a hospital located in Sari, Iran, in 2019. The eligible families of patients were assigned into two groups (N=80) through convenience sampling. The families in the experimental group were allowed to present in the ICU in a planned way. In the control group, the families just followed the restricted hospital visiting policy. The families’ perceptions of nurses’ caring behaviours in both groups were measured using the Caring Behaviour Inventory. Independent and paired t-tests were used for comparing families’ perceptions between and within the groups, respectively. Data were analysed by SPSS.
Results: A significant positive increase was found in the families’ perceptions in the experimental group after intervention (84.90 7.87), P<0.0001). The mean difference between the two groups was statistically significant, with a higher positive perception in the experimental group (33.78 (1.04), P<0.0001).
Conclusion: Planned presence in the ICU has an effective role in improving families’ positive perceptions of nurses’ caring behaviours. Therefore, reconsidering a restricted visiting policy is recommended.

Authors: TÜYSÜZ Şule , ÖNCEL Abidin
Published: September 2022

Bu çalışmanın amacı yeşil ekonomi olgusu açısından, Türkiye’de sürdürülebilir enerji kaynaklarının SWOT analizinin gerçekleştirilmesidir. Bu amaçla yeşil ekonomi olgusunun kavramsal ve teorik çerçevesi izah edildikten sonra Türkiye’de yeşil ekonomiye geçiş sürecinde uygulanan politikalar ele alınmıştır. Çalışmada yöntem olarak seçilen SWOT analizi sayesinde Türkiye’nin sürdürülebilir enerji kaynakları açısından güçlü yönleri, zayıf yönleri, fırsatlar ve tehditler belirlenmiştir. Araştırmanın bulguları, Türkiye’de potansiyel sürdürülebilir enerji kaynakları olarak hidroelektrik, rüzgâr ve güneş enerjisi kaynaklarını ön plana çıkarmaktadır. Türkiye’nin söz konusu enerji kaynakları açısından sahip olduğu yüksek potansiyel ve jeopolitik konumu önemli güçlü yönleri iken, ülkenin ekonomik durumu ve sürdürülebilir enerji politikalarının etkinsizliği ön plana çıkan önemli zayıf yönleridir. Küresel ölçekte ortaya çıkan konjonktürün enerjide dışa bağımlılığı daha fazla tartışılır hale getirmesi ve Türkiye’de yaşayan bireylerin sürdürülebilirlik yönünde farkındalıklarının artış yönünde olması önemli fırsatlardır. Sürdürülebilir enerji kaynaklarının artırılması noktasında santral kurulumları için bazı girdilerin dışarıdan temin edilme zorunluluğu, ülkede enerji ihtiyacının giderek artmasının getirdiği ilave talep ve hane halkının düşük gelire sahip olmasının getirdiği olumsuzluklar ise ön plana çıkan önemli tehditlerdir.
