Em dezembro de 2019 surge uma nova doença do trato respiratório altamente contagiosa na China, posteriormente essa doença se espalhou rapidamente por diversos países denominada COVID-19 levando a Organização Mundial da Saúde (OMS) a decretar estado de pandemia. Municipios com menor Índice de Desenvolvimento Humano IDH geralmente apresentam uma taxa de mortalidade mais alta em relação ao municípios com alto IDH, sendo isso em diversos tipos de enfermidades. O estado de Santa Catarina possui um IDH acima da média nacional, mas dentre os 295 municipios a diferença dos melhores com os piores municípios no IDH faz com que surja a pergunta: Será que o IDH tem associação com maiores taxas de mortes de COVID-19?

Abstract
The efficient processing of large-scale data has very important practical value. In this study, a data mining platform based on Hadoop distributed file system was designed, and then K-means algorithm was improved with the idea of max-min distance. On Hadoop distributed file system platform, the parallelization was realized by MapReduce. Finally, the data processing effect of the algorithm was analyzed with Iris data set. The results showed that the parallel algorithm divided more correct samples than the traditional algorithm; in the single-machine environment, the parallel algorithm ran longer; in the face of large data sets, the traditional algorithm had insufficient memory, but the parallel algorithm completed the calculation task; the acceleration ratio of the parallel algorithm was raised with the expansion of cluster size and data set size, showing a good parallel effect. The experimental results verifies the reliability of parallel algorithm in big data processing, which makes some contributions to further improve the efficiency of data mining.

Summary
Ammonium acid urate (AAU) crystals are rare in industrialized countries. Furthermore, the number of children with diabetic ketoacidosis (DKA) who develop severe acute kidney injury (AKI) after hospitalization is small. We encountered two patients with AKI caused by AAU crystals during the recovery phase of DKA upon admission. They were diagnosed with severe DKA and hyperuricemia. Their urine volume decreased and AKI developed several days after hospitalization; however, acidosis improved in both patients. Urine sediment analysis revealed AAU crystals. They were treated with urine alkalization and diuretics. Excretion of ammonia in the urine and urine pH levels increased after treatment of DKA, which resulted in the formation of AAU crystals. In patients with severe DKA, the urine and urine sediment should be carefully examined as AAU can form in the recovery phase of DKA.

Learning points:

Ammonium acid urate crystals could be formed in the recovery phase of diabetic ketoacidosis.

Diabetic ketoacidosis patients may develop acute kidney injury caused by ammonium acid urate crystals.

Urine and urine sediment should be carefully checked in patients with severe DKA who present with hyperuricemia and volume depletion.

Authors: Pusztai Tamas , Simenfalvi Zoltan 
Published: March 2021

AbstractSafety valves are the most important safety devices of the pressure system. For safety valves in the vast majority of cases in industrial environment, direct spring-loaded safety valves are used. The most important parameter of the equation of motion is the flow force. The main goal of the analysis was to compare the simulated flow forces with the measured results and validating the computational fluid dynamics model. Simulations were made in ANSYS 2019 R1 code for numerous fixed valve disk positions on different pressures. Results are in good agreement with the measured data.
Optimization of a flat slab with different type of punching reinforcement
Authors: Bujňáková Petra , Mečár Jakub 
Published: March 2021

AbstractSeveral types of punching shear reinforcements are available for increase of the maximum resistance against punching shear failure of flat slabs. Conventional punching shear reinforcement in form of stirrups or double headed studs are in use for decades. They are well known due to their simplicity and good performance. A new type of punching reinforcement has been developed for the case, where the flat slab exposed to extreme load and resistance of conventional type of punching shear reinforcement is not sufficient. Another designs point out that new construction system can reduce the amount of CO2. This paper presents some results of parametric study focused on design of the flat slab using different types of punching shear reinforcement and considering the concrete consumption.
BIOLOGIA REPRODUTIVA DE PEIXE COELHO SAPATEIRO, Siganus sutor (VALENCIENNES, 1835) EM CABO DELGADO, NORTE DE MOÇAMBIQUE

Published: March 2021

O peixe coelho sapateiro Siganus sutor é um dos recursos pesqueiros mais importante das pescarias artesanais em Cabo Delgado. No entanto, a legislação pesqueira em vigor não tem qualquer regulamentação da pesca desta espécie. O estudo da biologia reprodutiva desta espécie é importante na medida em que permite determinar medidas de conservação visando à manutenção dos estoques pesqueiros da espécie Siganus sutor. O presente estudo teve como objetivo determinar os aspetos da ecologia reprodutiva do Siganus sutor em Cabo Delgado. Foram coletados 724 indivíduos provenientes da pesca artesanal entre agosto de 2018 a julho de 2019. No laboratório procedeu-se a triagem dos dados biométricos (peso com 5 g de precisão e comprimento com precisão de 1 mm) de cada indivíduo. Posteriormente, os estágios das gonadas foram observados macroscopicamente usando uma escala de desenvolvimento, de imaturo ao desovado/aspermo baseado de critérios morfológicos. A proporção sexual para o período do estudo foi de 1,5 fêmeas para cada 1 macho. A primeira maturação foi de 187,01 mm de comprimento total para fêmeas e de 201,73 mm para machos. O período com maior proporção de peixes com gonadas maturas foi de abril a agosto. Perante este cenário, para manutenção das populações desta espécie, são sugeridas medidas de gestão que garantem a reprodução da espécie durante os meses de abril a agosto, a definição do tamanho mínimo de captura de 202 mm para fêmeas e machos.

Analisis keandalan akhir-akhir ini semakin banyak yang menggunakanya seiring dengan perkembangan ilmu pengetahuan dan teknologi. Bukan saja diaplikasikan pada bidang statistik yang menjadi induknya tetapi juga diberbagai bidang terutama pada analisis struktur yang erat hubungannya dengan peramalan dan analisa resiko. Floating Storage Offloading (FSO) merupakan struktur terapung di lautan seperti kapal tanker yang berfungsi untuk melakukan bongkar muat minyak. Dengan keberadaan FSO di lingkungan laut di mana tingkat ketidak pastian yang begitu tinggi maka analisis keandalan merupakan faktor penting yang seharusnya dilakukan. Dengan bantuan metode simulasi Monte Carlo maka analisis ini dapat dilakuan. Analisa Monte Carlo akan memberikan hasil yang dapat dijadikan rekomendasi dalam menganalisa kekuatan FSO. Metodologi yang dipakai untuk melakukan analisa ini adalah mengumpulkan data, menetapkan ambang batas keselamatan, menentukan karasteristik peubah dasar, dan kemudian melakukan simulasi Monte Carlo. Dengan demikian maka sesungguhnya analisis keandalan ini dapat diterapkan pada tahap-tahap perancangan dan perencanaan FOS atau kapal-kapal lain.

Published: March 2021

Abstract
Inhibiting the main protease of SARS-CoV-2 is of great interest in tackling the COVID-19 pandemic caused by the virus. Most efforts have been centred on inhibiting the binding site of the enzyme. However, considering allosteric sites, distant from the active or orthosteric site, broadens the search space for drug candidates and confers the advantages of allosteric drug targeting. Here, we report the allosteric communication pathways in the main protease dimer by using two novel fully atomistic graph theoretical methods: bond-to-bond propensity analysis, which has been previously successful in identifying allosteric sites without a priori knowledge in benchmark data sets, and, Markov transient analysis, which has previously aided in finding novel drug targets in catalytic protein families. We further score the highest-ranking sites against random sites in similar distances through statistical bootstrapping and identify four statistically significant putative allosteric sites as good candidates for alternative drug targeting.

Published: March 2021

Abstract
The Hospital Anxiety and Depression Scale (HADS) despite being widely studied in various populations, there is still no consensus on its factor structure. Our study aims to evaluate the psychometric properties of HADS in people with cancer. It involved 467 patients-diagnosed with cancer, who could read and write and were treated in a public institution specialized in cancer. It was found that HADS is best suited to a bifactorial structure where there is one general factor (emotional distress) and two specific factors (anxiety and depression). HADS proves to be invariant according to sex and years of education. It is moderately related to Beck's anxiety and depression inventory. Also, it presents acceptable levels of reliability and relationship with instruments used in the diagnosis of anxiety and depression. Its brevity, versatility, hospital-focused design, and extensive study make HADS a very important instrument in the detection of anxiety and depression in cancer patients.
Atlantic Zonal Mode-Monsoon Teleconnection in a Warming Scenario
Authors: T Sabeerali C. , Ravindran Ajaya Mohan , V Praveen 
Published: March 2021

Abstract
The dominant interannual SST variability in the eastern equatorial Atlantic referred to as the Atlantic Zonal Mode (AZM), which peaks in boreal summer impacts global weather patterns. The cold (warm) phase of this ocean-atmospheric coupled phenomenon enhances (weakens) the intensity of the Indian summer monsoon rainfall (ISMR). Observational studies show a strengthening relationship between AZM and ISMR in recent decades, providing a predictive signal for the ISMR. However, a suite of Coupled Model Intercomparison Project Phase 6 (CMIP6) model simulations in the highest emission scenario (SSP58.5) show a weakening relationship between ISMR and AZM in the future (2050-2099). The strengthening of atmospheric thermal stability over the tropical Atlantic in the warming scenario weakens the associated convection over the eastern equatorial Atlantic in response to the warm phase of AZM. This leads to weakening velocity potential response over the Indian subcontinent, resulting in a weak AZM-ISMR relationship. There is no convincing evidence to indicate that either the tropical Atlantic SST bias or the AZM-ISMR teleconnection bias plays a crucial role in the potential weakening of this relationship. These results imply that ISMR prediction will become more challenging in a warming scenario as one of the major external boundary forces that influence monsoon weakens.

Published: March 2021

Abstract
Wake galloping energy harvesting have been extensively developed to scavenge flow energy from vortex-induced oscillations. Hence, the wake-galloping harvester only has a natural frequency which leads to a very narrow bandwidth. Therefore, it does not operate well under the wide region of shedding frequencies in variable wind speed. To overcome the vital issue, this paper we explored a novel two-degree-of-freedom nonlinear flow energy harvester to collect flow energy induced by the wake of a bluff body. The nonlinear restoring force is realized by using a repulsive magnetic force between two cuboid-shaped permanent magnets, and the electromechanical coupling equations is presented. Based on the method of harmonic balance, the electromechanical governing equations is decoupled, and the first order harmonic solutions are implemented. The modulation equations are established, the amplitude-frequency figures of displacement and voltage are depicted with different detuning parameters. The superiority of the presented energy harvester is contrasted with the single-degree-of-freedom linear and nonlinear cases, the results revealed that the two-degree-of-freedom nonlinear scheme can enhance the bandwidth of flow energy capture. The effect of physical parameters on the scavenged power is discussed. The accuracy and efficiency of the approximate analytical data are examined by numerical simulations.
Adaptations of market garden producers to climate change in southern Mali
Authors: SOUMAORO Tiémoko 
Published: March 2021

Abstract
This article aims to identify the factors that influence the choice of adaptation measures by market garden producers in the extreme south of Mali in the face of climate change. The study used a multinomial logit regression model based on data collected from producers. Interviews with 194 producers were conducted in 3 circles in the southern region: Sikasso, Koutiala and Bougouni. The results of the multinomial logit model indicate that the mode of access to land, access to information on climate change, agricultural extension, agricultural experience and access to credit are the main endogenous strategies developed by producers to counteract the impacts of climate change. Finally, in order to consolidate these different strategies developed by producers, campaigns to raise awareness among producers on the importance of adapting to climate change should be encouraged.

Published: March 2021

Abstract
Despite the importance of remittance inflows as potential source of incomes for recipient households and one of main contributors to the development process in various developing countries, their environmental effects have been largely neglected in empirical literature. To fill this gap, the current study proposes an extension of the conventional environmental Kuznets curve (EKC) by performing a modified version based on remittance inflows in both Low- and middle-income countries (LMICs) from 1980 to 2014. Using the novel method of moments quantile regression with fixed effect (MM-QR), the outcomes provide evidence of an inverted N-Shaped EKC for remittances at higher CO2 emitters in lower-middle income countries (LMIC), proving that remittances allow recipient households to shift towards clean energy pattern (production/consumption). We find U-Shaped EKC for remittances from the 40th to 80th quantiles in upper middle-income countries (UMIC) along with monotonic negative effect on CO2 emissions at highest quantiles (90th and 95th ). No significant effect on environment has been outlined at lower CO2 emitters for all panels. Regarding GDP per capita, an inverted N-Shaped EKC has been observed across all quantiles in UMIC and from lower to middle quantiles in Low-income countries (LIC). Finally, financial development (FD), as control variable, exerts significant mixed effect on CO2 emissions, swung between positive at all quantiles in LMIC and UMIC and negative at lower quantiles in LIC. Some recommendations were further built in the present study.

Abstract
Background: Hypovolemic shock occurs due to many causes and it has complex patho-physiology which finally leads to decreased all organs perfusion. Transcutaneous electrical nerve stimulation (TENS) consists of a generic application of low-frequency, pulsed electrical currents transmitted by electrodes through the skin surface to stimulate the primary afferent pathways (peripheral nerves) to produce various physiological effects.Objective: Was to evaluate the effect of transcutaneous electrical nerve stimulation application on the renal tissue perfusion and hemodynamic stability for patients with hypovolemic shock.Design: A prospective, single-blind, randomized, sham-controlled trial. Patients were randomized into two groups (active TENS versus sham TENS). Active TENS group received resuscitation protocol and transcutaneous electrical nerve stimulation while sham TENS group received resuscitation protocol only.Setting: Data was collected from general and obstetric ICU.Main Outcome Measures: Improvement of renal tissue perfusion was considered the primary outcome and secondary outcomes was improvement of hemodynamic parameters.Results: TENS application had caused a highly statistical significant change in serum Creatinine and NGAL test (74.43 ± 7.16 in active TENS versus 114.48 ± 13.6 2 in sham TENS) and (7.35 ± 0.7716 in active TENS versus 20.76 ± 2.11 in sham TENS) (P = 0.007 & P= 0.000) respectively. There was highly statistical significant difference before treatment and after treatment regarding urea, creatinine and NGAL test in the control group (P= 0.002 & P= 0.006& P= 0.000) respectively and there was highly statistical significant difference before treatment and after treatment in TENS group regarding to serum Creatinine (P= 0.003).Conclusion: We concluded the following; Application of TENS is extremely effective on improvement of renal tissue perfusion and and hemodynamic parameters. Also TENS should be used as a nursing intervention to maintain hemodynamic stability in patients with hypovolemic shock in the intensive care unit and we found patients with hypovolemic shock who received active TENS had better outcomes than patients who received sham TENS.

Published: March 2021

Abstract
Mining and mineral processing are often associated with heavy metal pollution. To reflect the environmental conditions of manganese carbonate ore deposits and of the area surrounding an electrolytic manganese plant, we analyzed the composition and species diversity of bryophyte communities and determined the differences in bryophyte communities related to the content of heavy metals in the substrate. We found that Pottiaceae and Bryaceae were the dominant families in the study area. The species abundance index of bryophyte communities at different locations was in order: vicinity of the mine > mine site > herb-shrubland > electrolytic plant > electrolytic waste dump. The species diversity of bryophyte communities at different locations was in order: herb-shrubland > vicinity of the mine > electrolytic waste dump > mine site > electrolytic plant. Significant differences between heavy metal contents of the substrate were found among the different locations with the exception of Co (p < 0.05). Mn contents were significantly different at each location (p < 0.05). CCA showed that Mn, Cd, Hg, and Pb content in the substrate were the major factors affecting the characteristics of the bryophyte communities. From the combination of CCA with the correlation heat map, it can be inferred that Hg, Mn, and Cu all have an adverse effect on bryophyte communities in the vicinity of the mine and in the herb-shrubland. Thus the determination of the characteristics of bryophyte communities allows ready identification of the impact of heavy metals on the environment, in turn providing a mechanism for decision-making in terms of pollution management and biodiversity protection.

Abstract
Background

Community-associated Methicillin-resistant Staphylococcus aureus (CA-MRSA) is an emerging pathogen that leads to severe outcomes, especially in pediatric patients with multiple site infections.
Case presentation:

We report a case of a multiple organ and life-threatening infection caused by CA-MRSA in a 6-year-old girl who manifested sepsis, myelitis, purulent arthritis, purulent meningitis, hydropericardium, pneumonia, and empyema. The girl exhibited good response to the combination therapy of linezolid and rifampicin after treatment with vancomycin failed due to delay in achieving target serum concentration. We performed pleural effusion and hydropericardium effusion drainage and treated left lower limb infection using interdisciplinary approaches.
Conclusion

This case highlights the need to be aware of CA-MRSA infection, which requires accurate diagnosis, identification of site infection, appropriate antibiotic treatment, and surgical debridement.
