Teaching chemistry should be instigating, problematizing, and challenging, in a way that the aim is to build the student's scientific knowledge. In this way, the present work seeks to contribute, descriptively, as a motivating tool for learning knowledge in the science area, with a focus on chemistry. It is noticed that even with the various current academic productions, there is a lack of works that portray the reality of the teacher in the classrooms in Youth and Adults Education (YAE), particularly with chemistry content. Intending to assist the challenges experienced by education professionals and students, in the school context of YAE, and to arouse curiosity and interest in learning, we sought to bring playfulness to the classroom. Thus, the objective of this work was to develop a board game that makes the content of the Periodic Table clearer and more accessible, instigating its problematization and contextualization. The work is based on the theory of Meaningful Learning that fits the current reality of students and teachers of YAE, who bring all their experience to be shared in the classroom. For this purpose, a game was built and this work will explain its sequence of elaboration, as well as discuss ways to implement it in the chemistry classes for YAE. The work will emphasize the importance of contextualizing chemistry through the QuimiVille game, which familiarizes students with the Periodic Table, promoting that the teaching and learning process is concrete, contextualized, and meaningful.Keywords: Youth and Adults Education.

Corn has great economic importance, being the most produced cereal in the world, and most of this production is destinated for animal feed. In order to reduce production costs and risks, and increase the feed efficiency of ruminants, rehydrated corn silage is a good alternative. The objective of this study was to evaluate the nutritional quality of rehydrated corn grain silage with four different levels of humidity. The experiment was conducted at the Agricultural Center in Federal Institute of Southeastern Minas – Campus Barbacena. The experimental design utilized was completely randomized. The treatments consisted of corn grain without reydratation (control), corn grain rehydrated with 30% moisture, corn grain rehydrated with 35% moisture, corn grain rehydrated at 40% moisture and corn grain rehydrated with 45% moisture, totaling 25 experimental silos. After 56 days the silos were opened and the levels of dry matter, crude protein, mineral mixture and pH were evaluated. The results showed that the quality of the silage was influenced in its DM and pH by the treatments with inclusion of water, reaching values of 70,74% of MS and 5,01 of pH in treatment with 45% of moisture. No influence was observed in PB and MM values. It was concluded tha the silage of rehydrated corn grain was influenced by the inclusion of water.

Canine Venereal Tumor is one of the few types of contagious tumors described in mammals. It is transplanted as a viable cell allograft into mucous and/or skin, where it triggers an immune process that varies according to the stage of development. The TVT has 4 phases; the phase of progression (P) characterized by the evasion of the histocompatibility barrier and the immune response by immunosuppressive mechanisms, followed by the stagnation phase (E) in which a process of stasis occurs between the tumor and the immune system that allows the remodeling of damaged tissue, in the regression phase (R), the main event is the reactivation of the immune response mediated by infiltrating T lymphocytes and proinflammatory cytokines such as interleukin IL-6 and gamma interferon (IFN- γ), for the removal of the tumor. The Metastasis (M) phase, or tumor spread, develops in non-immunocompetent hosts. This review describes in detail the immune processes carried out in each phase.

Mucinose cutânea em um cão da raça Shar pei: Relato de caso
Authors: Umbria Bruna
Published: May 2021

Cutaneous mucinosis is a primary idiopathic dermatopathy that occurs in dogs of the Shar pei breed, characterized by excessive deposition of mucin in the dermis that leads to the presentation of skin folds, and in more severe cases the formation of vesicles or blisters. Hyaluronic acid has been identified as the main component of mucin, however the etiopathogenesis, prevention and treatment of this disease have not yet been fully elucidated. This paper reports a 3-year-old Shar pei dog, diagnosed with cutaneous mucinosis. On physical examination, multiple vesicles containing transparent and viscous fluid and hypotrichosis were observed in the ventral region of the neck, armpits, bilateral flank, perianal and in the distal portion of the limbs. In the pelvic limbs there was also the presence of edema. The affected skin was swollen, thickened and negative at Godet's sign. Blood tests, scrapes and skin cytology were performed. Blood tests did not show any significant alterations, as well as scraping and skin cytology showed negative results. Based on these results, it was decided to perform a skin biopsy and histopathological analysis. Intense and diffuse myxomatous edema was observed, mainly in the most superficial and perianexal region, with the formation of mucin lakes, confirming the diagnosis. For treatment, prednisolone was prescribed at a dose of 1 mg / kg every 24 hours, for 7 days, reducing the dose until the drug was discontinued in 30 days. After 21 days of treatment, the patient had complete resolution of the lesions and itching. It was possible to conclude that cutaneous mucinosis is an exclusive dermatopathy of dogs of the Shar pei breed due to the intense genetic selection throughout the breed's history. The impact of high hyaluronic acid synthesis on the phenotype of these dogs is only partially known. In this way, many other sites and systemic effects of hyaluronic acid still need to be understood since this glycosaminoglycan is synthesized by several cells and can be found in various tissues and body fluids with varying concentrations.Hyaluronic acid, dogs, dermatopathy, mucin
Uso de pele de tilápia em disjunção de sínfise mandibular em felino: Relato de caso
Authors: De Sousa Francielle
Published: May 2021

Mandibular trauma is common in small animals and the region most affected in cats is the mental symphysis. With the traumatic impact, the animal presents a picture of injuries with discontinuity of anatomical and cellular tissues, leading to open and unexposed fractures. As therapeutic options, there are surgical methods such as intramedullary pin, external skeletal fixation, cerclage and the use of acrylics and bone plates. For the injured region, the use of cheap and flexible dressings is recommended, providing comfort and well-being to the patient, so that in the end it reaches the consolidation of the symphysis and restores oral functionality to the animal. Therefore, the use of Nile tilapia skin appears as an alternative to biological material, providing all the characteristics that the animal needs for re-epithelialization, comfort, flexibility, excellent adhesion and reduction of hydroelectrolytic losses. Therefore, this work aims to report the use of Nile tilapia skin associated with Dersani® ointment as a temporary occlusive dressing in mandibular symphysis disjunction after epithelial necrosis, in a feline, SRD of approximately 4 months of age. The skin was previously prepared at the Centro Universitário do Cerrado (UNICERP), in a sterile laboratory. For this, a 2% chlorhexidine solution was used and a 0.9% saline solution. The technique was repeated 3 times, always removing all material from the harness that would not be used, preserving the scales and leather of the product. After cleaning, the material was packaged, identified and stored in the refrigerator for refrigeration, using 80% saline solution and 20% glycerin as storage medium. Then, the size of the edges was measured with the use of a caliper and subsequently the area of the lesion was cleaned and scarified for placement of the biological material. The tilapia skin was changed every 3-4 days, always checking the evolution of the wound and the presence of infections and inflammations, for approximately 17 days. In short, we observed the evolution of the wound that always remained clean and free of infections, leaving the animal calm and well-being. The technique proved to be effective, bringing agility in the postoperative and monetarily more viable to the owner.

Microdialysis in vivo Evaluation of the effects of SA-4503, a Sigma1 Receptor Agonist, on the Levels of Monoamines in the Prefrontal Cortex of Conscious Rats
Authors: Crespi Francesco
Published: May 2021

Sigma receptors are widespread in the central nervous system and are differentiated in two subtypes, sigma1 and sigma2. In particular, the sigma1 receptor subtype appears to be able to influence biological mechanisms connected with neuro-degeneration. Furthermore, several studies are implicating sigma1 receptor agonists within antidepressant activity. Evidence of prefrontal cortex abnormalities in clinically depressed subjects have been reported by several works and that monoamines such as serotonin and cathecolamines can be involved in such malfunctions. Up to now the most of the preclinical work performed to analyze the influence of sigma1 receptor agonists upon catecholaminergic and serotoninergic activities in brain areas has been done by means of in vitro as well as ex vivo methodologies. Here, SA-4503, a selective sigma1 receptor agonist with potential antidepressant activity has been tested in vivo upon dopamine (DA), noradrenaline (NA) and serotonin (5-HT) levels detected by micro-dialysis in the medial Prefrontal Cortex (mPFC) of freely moving rats.

Ménière's disease (also known as Ménière's vertigo) is a condition characterized by disabling recurrent vertigo, sensorineural hearing loss, otic fullness, and tinnitus. There are various treatments to manage this entity, however, in certain cases, the lack of improvement with less aggressive strategies and the great impact on the quality of life of the patient requires radical procedures such as vestibular neurectomy. By means of a lateral suboccipital approach (retrosigmoid craniectomy) the best exposure of the vestibular nerve, its selective isolation and section is obtained, also allowing to preserve hearing and the entire facial nerve supported with neurophysiological monitoring techniques.
ANALISIS PENGARUH PERUBAHAN SUHU EVAPORATOR TERHADAP KINERJA KOMPRESOR AC INVERTER
Authors: Mayrullah Fahriza
Published: May 2021

Teknologi inverter yang diaplikasikan pada air conditioner menggunakan motor bldc 3 phasa sebagai penggerak kompresor. Motor BLDC 3 phasa dikemudikan oleh IPM (intelligent power module) dan mikrokontroller. Pada saat AC inverter dihidupkan, sesaat mikrokontroller akan membaca input data dari sensor-sensor temperatur, tekanan refrigeran, kemudian mencari posisi rotor untuk melakukan komutasi elektrik. Rentang pengkondisian suhu adalah 16oC – 30oC. Jika target suhu (TS) yang dipilih lebih rendah dari suhu aktual evaporator (SE), maka motor kompresor akan berputar maksimal. Setelah AC on dan SE sudah lebih rendah dari TS maka putaran kecepatan motor kompresor akan pelan. Variasi kecepatan ini menyebabkan energi (E) yang digunakan juga berubah-ubah. Penulis tertarik untuk melakukan penelitian pengaruh perubahan suhu evaporator (PSE) terhadap kinerja kompresor (COP dan EER). Penelitian akan dilakukan selama 2 jam dengan pengambilan data per 15 menit.  Tujuan dari penelitian ini yang pertama adalah mengidentifikasikan PSE dan kinerja kompresor (COP dan EER) kemudian yang kedua adalah mengetahui PSE dan pengaruhnya terhadap kinerja kompresor (COP dan EER) selama 2 jam. PSE adalah nilai suhu akhir evaporator dikurangi dengan nilai suhu awal evaporator. COP (coefficient of performance) atau koefisien prestasi adalah salah satu indeks dari kinerja kompresor berdasarkan kerja kompresor. Dimana semakin tinggi nilai COP maka kinerja kompresor semakin baik. EER (Energy Efficiency Ratio) merupakan rasio perbandingan antara energi yang digunakan dengan beban pendingan (cooling load) atau dikenal juga kW/ton. Semakin tinggi nilai EER maka efisiensi dari kompresor semakin tinggi. Jadi semakin tinggi nilai COP dan EER maka kinerja kompresor semakin baik. Dari hasil pengukuran dan perhitungan didapatkan untuk nilai terendah PSE= -7,2 menghasilkan nilai COP dan EER tertinggi yaitu, COP=22,27 dan EER=76,00. Pada bagian kesimpulan didapatkan analisa bahwa semakin kecil perubahan suhu evaporator (PSE) maka kinerja kompresor AC inverter semakin baik. kata kunci : ac, inverter, evaporator, kinerja, kompresor

Published: May 2021

Ultrasound study allows for quick and accurate assessment of pancreas. Two parameters are used for ultrasound characteristic of morphological change in pancreatic parenchyma: total echogenicity and a distribution pattern of reflected echo signals. It is widely known that an increase of echogenicity in pancreatic parenchyma along with an emergence of uneven distribution of echo signals, that possess a diffusive distribution patterns, may characterize age related changes and be a manifestation of a disease. Two of the most common pancreatic diseases that are characterized by identical diffusive changes in the structure of the parenchyma are acute pancreatitis and diabetes mellitus. However, stiffness indicators observed in patients with diabetes mellitus and acute pancreatitis are different - 5.1+ 1.7 and 9.1 +4.1 respectively. Differences in that level of the compared groups are statistically significant (p<0.05), as calculated using Mann-Whitney U test.

POETRY, PHILOSOPHY, TECHNOLOGY IN THE LIGHT OF CULTUROLOGY: DIALOGUE STRATEGY
Authors: Bilchenko E.
Published: May 2021

In the article, on the interdisciplinary methodological basis of the classical semiotics of culture and cultural comparative studies, supplemented by the developments of Lacanism and post-Lacanian psychoanalysis of the Ljubljana school, information aesthetics and tranzaesthetics, critical theory, French structuralism and poststructuralism, a strategy of dialogue between poetry and philosophy as the phenomena of traditional Logos in postmoderism is developed. ... The main problem of the modern poetic word is the loss of ontological adequations and spiritual implications by the text as a result of the inclusion of artistic creativity in the cyberspace of global digital multicultural capitalism. A comparative analysis of the projects of globalism and anti-globalism has demonstrated the priority of commercial culture as a prestigious social model for the formation of the poet's symbolic capital and network promotion. The orientation of the free market towards the sponsor's occupation of poetic creativity increasingly deprives poetry of the semantic invariants of authentic civilizational memory, which is eroded by trends in branding, advertising, and image, and is transformed into a souvenir, simulacrum, ersatz, and trademark. The only guarantor of the actualization of the basic cultural meanings of poetry is traditionalism, but its often grotesque, ultra-conservative and nostalgic character is not able to maintain the competitiveness of the tradition, its attractiveness for the younger generation and vivid personal subjectivity. A harmonious balance between traditionalism and postmodernism in poetry is possible if new technologies are used as forms of presentation and means of promoting the classical poetic tradition in the modern world, while maintaining the primacy of the goal for poetry, in relation to which the “creativity” of managerial entrepreneurship is a secondary means. We regard poetry as a point of semiotic intersection of a static sign in space (syntagma) and dynamic meaning in time (paradigm). Inside this point, in the zero phoneme, the author resides, regaining integrity, continuity, essence and selfhood instead of gaping, alienation and lack due to the correct correlation of the ontological goals of poetry and its ontic cases. Poetry in this context is a kind of a formula for the harmony of the metonymy of the real-symbolic language of culture and the metaphor of its ideal imaginary meanings. To find harmony between tradition and innovation, metaphysics and dialectics, synchronicity and diachrony, the gene code of culture and a historically labile cultural image is capable of culturology as a science based on philosophy (ontology and axiology), philology (hermeneutics and journalism), social sciences.

Voluntary Disclosure of Integrated Reporting and cost of Capital in Brazil: an Alternative Explanation
Authors: Ximenes de Aragao Vale Caste Debora , Nossa Valcemiro , Moraes da Costa Fábio , Soares Monte-Mor Danilo
Published: May 2021

There is an ongoing debate about whether integrated reporting should be mandatory or voluntary. Empirical evidence mostly focused on South African mandatory disclosures, indicate that the firm’s information environment is relevant to explain the effects on the cost of capital. However, results based on voluntary disclosures indicate that the country’s level of enforcement explains the effects. This paper analyses the effects of voluntary disclosures of integrated reports on the cost of capital for Brazilian listed companies. Our design is developed to control the level of enforcement and evaluate if firm‐specific characteristics may explain the effects on information asymmetry related to the disclosure of integrated financial and non‐financial informaƟon. We collect data from 2014 to 2017 and compare the effects on capital cost for a group of firms that voluntarily disclose integrated reports with a control group identified via Propensity Score Matching. We can identify that larger firms, with stronger corporate governance and lower risk, are more likely to voluntarily disclose integrated reports. In our second stage, we find no effect on the cost of capital after the voluntary disclosure. Taken together, our results are aligned with prior studies focused on mandatory disclosures: the firm’s information environment is relevant to explain the potential capital market benefits of Integrated Reporting.

Two-phase imperialist competitive algorithm for energy-efficient flexible job shop scheduling
Authors: Guo Jiong , Lei Deming , Li Ming
Published: May 2021

Energy-efficient flexible job shop scheduling problems (EFJSP) have been investigated fully; however, energy-related objectives often have lower importance than other ones in many real-life situations and this case is hardly considered in the previous works. In this study, EFJSP with sequence-dependent setup times (SDST) is considered, in which total tardiness and makespan are given higher importance than total energy consumption. A two-phase imperialist competitive algorithm (TPICA) is proposed. The importance difference among objectives is implemented by treating all objectives equally in the first phase and making energy consumption not to exceed a diminishing threshold in the second phase. A dynamical differentiating assimilation and a novel imperialist competition with the enforced search are implemented. Extensive experiments are conducted and the computational results show that TPICA is very competitive for EFJSP with SDST.

BACKGROUND: Nearly half of individuals post-stroke are dependent in their daily activities. The ability to ascend and descend stairs is an important component of independence in the community. OBJECTIVE: To predict the future ability of post-stroke individuals at the beginning of the sub-acute rehabilitation phase to achieve ascending and descending staircase independence. METHODS: 36 participants were recruited for the study. Outcome measures: independence in ascending and descending stairs up to the end of the sub-acute rehabilitation phase. Predictive measures included the knee extensors Muscles Strength (MS), the seated Modified Functional Reach (MFR) test, and Heart Rate Variability (HRV) measures. Logistic and Cox regression were used. RESULTS: Twenty-four participants (66.7%) completed the sub-acute rehabilitation phase being independent in ascending and descending stairs. MFR was the best predictor (R2 = 0.18), and with MS the best predictors for the time (days) to achieve this goal during the sub-acute rehabilitation. HRV measure was found to be the main predictor of the staircase ascent model (R2 = 0.32), and MFR the best predictor for the descent model (R2 = 0.24). CONCLUSIONS: Balance performance is the main predictor of independence in ascending and descending stairs. Improving this component during the sub-acute rehabilitation phase might be reflected in achieving staircase independence.

BACKGROUND: Aquatic exercises are among the treatments available to improve the quality of life after stroke. OBJECTIVES: To investigate changes in the quality of life after 8-week of aquatic exercises in post-stroke individuals. METHODS: A case series study was designed, including four male participants. Exclusive aquatic exercise was performed for 8-week, 50 minutes per session, 2×/week. Their quality of life was evaluated before and after the intervention using the Stroke Impact Scale (SIS). RESULTS: Participant 1 improved in the mobility domain, achieving a Clinically Important Difference (CID). Participant 2 improved in the strength and mobility domain, achieving CID; his stroke recovery was 6%, and it reached 50% post-intervention. Participant 3 improved in the mobility domain, achieving a CID and a Minimal Detectable Change (MDC); his stroke recovery increased from 45 to 60% post-intervention. Participant 4 improved the strength, mobility, and activities of daily living domains, achieving a CID and a MDC, but his stroke recovery remained unchanged at 80%. CONCLUSIONS: All participants achieved a CID in the mobility domain; thus, the aquatic exercise intervention was considered meaningful. Moreover, the SIS is able to evaluate aspects of the recovery process regarding health-related quality of life after stroke, as demonstrated by the results of the overall recovery after aquatic exercises.

BACKGROUND:

Acute ischemic stroke (AIS) results in high morbidity, disability, and mortality. Early and automatic diagnosis of AIS can help clinicians administer the appropriate interventions.

OBJECTIVE:

To develop a deep symmetric 3D convolutional neural network (DeepSym-3D-CNN) for automated AIS diagnosis via diffusion-weighted imaging (DWI) images.

METHODS:

This study includes 190 study subjects (97 AIS and 93 Non-AIS) by collecting both DWI and Apparent Diffusion Coefficient (ADC) images. 3D DWI brain images are split into left and right hemispheres and input into two paths. A map with 125×253×14×12 features is extracted by each path of Inception Modules. After the features computed from two paths are subtracted through L-2 normalization, four multi-scale convolution layers produce the final predation. Three comparative models using DWI images including MedicalNet with transfer learning, Simple DeepSym-3D-CNN (each 3D Inception Module is replaced by a simple 3D-CNN layer), and L-1 DeepSym-3D-CNN (L-2 normalization is replaced by L-1 normalization) are constructed. Moreover, using ADC images and the combination of DWI and ADC images as inputs, the performance of DeepSym-3D-CNN is also investigated. Performance levels of all three models are evaluated by 5-fold cross-validation and the values of area under ROC curve (AUC) are compared by DeLong’s test.

RESULTS:

DeepSym-3D-CNN achieves an accuracy of 0.850 and an AUC of 0.864. DeLong’s test of AUC values demonstrates that DeepSym-3D-CNN significantly outperforms other comparative models ( p < 0.05). The highlighted regions in the feature maps of DeepSym-3D-CNN spatially match with AIS lesions. Meanwhile, DeepSym-3D-CNN using DWI images presents the significant higher AUC than that either using ADC images or using DWI-ADC images based on DeLong’s test ( p < 0.05).

CONCLUSIONS:

DeepSym-3D-CNN is a potential method for automatically identifying AIS via DWI images and can be extended to other diseases with asymmetric lesions.
Evaluation of Polyphenols Enriched Dairy Products Developed by Incorporating Black Carrot (Daucus carota L.) Concentrate
Authors: Pandey Pragya
Published: May 2021

Background: Dairy products like ice cream, yogurt and buttermilk are consumed widely due to their rich taste but these products lack anthocyanins, which are polyphenol and exhibit great antioxidant activity in both in vivo and in vitro studies. Therefore, adding a natural source of these antioxidants to the commonly consumed dairy product will be beneficial to the masses. Among all the sources, black carrots are the extraordinary and cheapest source of anthocyanins, which are commonly consumed as a natural fermented drink. In this study, an attempt has been made to examine the feasibility of black carrot concentrate as an ingredient into dairy products.

Methodology: Ice cream, yogurt and buttermilk were prepared by incorporating black carrot concentrate at 2.5, 5.0, 7.5 and 10% level and were subjected to sensory analysis. The most acceptable products with 7.5% black carrot concentrate were analyzed for minerals, polyphenols and antioxidant activity. Effects of storage on physicochemical, microbial and sensory attributes of black carrot concentrate incorporated dairy products were further analyzed.

Results: Sensory analysis revealed that black carrot concentrate could be used up to 7.5% as an ingredient into dairy product with high acceptability. Significant improvement in mineral content (Mg and Fe), polyphenols and antioxidant activity were reported in black carrot concentrate added dairy products. Developed dairy products exhibited an excellent amount of 24.52 to 113.27 mg/100g anthocyanins. Flavonoids increased by 14.52 to 34.62 times and Folin-Ciocalteu reducing capacity increased by 26.39 to 35.87 times in experimental dairy products. The storage study revealed that ice cream could be stored for more than 60 days, yogurt up to 5 days and buttermilk up to 10 days with excellent stability attributes.

Conclusion: Incorporation of black carrot concentrate at the level of 7.5% resulted in high acceptability and exceptional nutraceutical property of dairy products. Incorporation of black carrot concentrate into dairy products would enhance the nutraceutical properties and mineral content of food, which could be highly significant in preventing hidden hunger and oxidative stress-induced disorders in developing countries.
