Published: February 2022

Menurut para pemakai connecting pad local, waktu umur pakainya lebih pendek dibandingkan dengan yang asli. Dikarenakan kekerasan connecting pad asli lebih besar dibanding dengan connecting pad lokal, dimana secara teoritis kekerasan sejalan dengan ketahanan aus, dengan kata lain apabila suatu material semakin keras maka akan semakin baik ketahanan ausnya. Dengan proses Precipitation hardening pada connecting pad lokal diharapkan material connecting pad lokal akan meningkat kekerasannya sehingga connecting pad lokal tersebut meningkat ketahanan ausnya dan diharabkan mendekati connecting pad aslinya.

The effect of oil pollution and phytoremediation with Zea mays L. and Vicia faba var. Minor on soil oxidoreductase activity was investigated. The experiment was carried out under field conditions. Soil was artificially contaminated by oil at rate 4.2 % (50 ml of oil per 1 kg of soil). Soil sampling was performed at 10th, 22th, 30th days (the firs experiment stage) before sowing plants and seedlings emergence and at 65th, 95th days (second experiment stage) with plants vegetation. Results showed that soil catalase activity (CA) was reduced during the first experiment stage and increased later under oil contamination conditions compared to control. The reduction of soil enzyme activity can be related to inhibition of soil microbial activity by hydrocarbons toxic influence. On the other hand recovery of enzyme activity can be due to decrease of toxicity of soil conditions over time. A two-way analysis of variance yielded a main effect for the phytoremediation (p<0,01), such that the average CA was significantly higher for soil with plants than for unplanted soil. The interaction effect was significant between oil contamination and phytoremediation with Z. mays (p<0,01), indicating that the plants’ effect was greater in the oil contamination condition than without oil contamination. Soil dehydrogenase activity (DA) in oil contamination conditions decreased during all experiment compared to control. A main effect of phytoremediation on DA was significant (p<0,05), the interaction effect between oil contamination and phytoremediation was significant too (p<0,05). Interaction effect between oil contamination and phytoremediation can indicate improving conditions for microbial activity in the rooting zone. The plant’s exudates may create more feasible conditions for utilisation of carbohydrates by microorganisms. Polyphenol oxidase (PPOA) activity decreased on the 95th day in oil contaminated soil compared to control. PPOA was stimulated by Z. mays and V. faba plants in soil without oil, and only by Z. mays in oil contaminated soil. Soil phytoremediation treatment was related to the increase of enzyme activity. Such plants can be feasible for oil contaminated soil remediation.

The influence of different concentrations of the indolebutyric acid (ІВА) during the claying of the root system on morphometric rates of the scotch pine (Pinus sylvestris L.) seedlings on the waste heap of coal mines and the pitch pine (Pinus rigida Mill.) in the conditions of growth on technogenic substrates of a dump in model experiments was studied. It was found that the application of the claying method of the pine root system with the simultaneous addition of the IВА contributes to a significant increase of the growth parameters of aboveground phytomass and development of the root system both model and field experiments. The largest number of roots in the pitch pine (laboratory conditions) was stimulated concentrations of the IBA – 100 and 200 mg / kg of clay on a black substrate (296 %), and of the roots mass of the same concentrations – on the red substrate (795 % and 788 %, respectively). On the black substrate all concentrations of the indolebutyric acid (50, 100, 200 mg / kg of clay) much better stimulated shoot length, in particular the IBA of 100 mg / kg of clay (244 %). On the red substrate under the action of the IBA all the ratios to clay shoot growth was slower than on the black. However, a significant accumulation of his biomass was observed, in particular at a concentration of the IВА 100 mg / kg of clay – 554 %. It was studied that of the scotch pine seedlings, which grew on the waste heap of the Central Сoncentrating Factory during 2 and 3 years, also increased their morphometric parameters with using of clay and the indolеbutyric acid in different concentrations. It was found that in 2-year-old spruce seedlings the maximum phytomass of the shoot (438 %) was set at the ratio of IВА to clay – 100 mg / kg of clay. Indolеbutyric acid at concentrations of 100 and 200 mg / kg of clay significantly affected on formation of root biomass in plants – 748 % and 690 %, respectively. In the 3-rd year of growth of the scotch pine on technogenic substrates, a significant accumulation of the root mass was observed at concentrations of indolebutyric acid of 100 and 200 mg / kg of clay – 1168–1189 %, respectively. Aboveground phytomass was the largest (777 %) at a concentration 100 mg / kg of clay. It is established that the optimal concentration for plant ontogenesis is the indolebutyric acid at the ratio of 100 mg / kg of clay in both model and field experiments.

Published: February 2022

Tomato (Lycopersicum esculentum Mill.) is a plant that is rich in benefits, but the yield is still low, some of which are due to a lack of nutrients, one of which is micro nutrient zinc, and improper plant spacing. The research was carried out to determine: 1) the best dose of Zn fertilizer and the right plant spacing; 2) the interaction between Zn fertilizer dosage and plant spacing; 3) the relationship (correlation) between the two observed variables. The research was conducted from July to October 2018 in Teluk Dalam Village, Mulawarman Village, Tenggarong Seberang District, Kutai Kartanegara Regency. The 4x3 factorial experiment was arranged in a Randomized Complete Block Design with three replications. The first factor was the dose of Zn fertilizer, consisting of four levels, namely 0.00; 3.00; 6.00; and 9.00 kg Zn ha-1. The second factor was plant spacing, consisting of: 50 cm x 50 cm; 60 cm x 50 cm; 70 cm x 50 cm. Data were analyzed using analysis of variance, followed by the LSD test at the 5% level. Correlation analysis was used to determine the relationship between two quantitative variables. The results showed that the effect of Zn fertilizer dosage was significantly different on plant height and plant age at first harvest, number of fruit per plant, fruit fresh weight per plant, harvest frequency, and fruit fresh weight per hectare, but not significantly different on plant height and age plants at flowering and the number of branches per plant. The effect of plant spacing was significantly different, on the other hand, the interaction was not significantly different on all observed variables. The best dose of Zn fertilizer is 6.00 kg ha-1 with fruit fresh weight 25.16 Mg ha-1 and the best plant spacing is 70 cm x 50 cm with fruit fresh weight 25.18 Mg ha-1. The results of the correlation analysis showed that fruit fresh weight per hectare had a positive correlation with the number of fruit, fruit fresh weight per plant, and the frequency of harvest with the correlation coefficient (r), respectively 0.7350; 0.8190; and 0.6316, but negatively correlated with plant age at flowering and first harvest, namely -0.2552 and -0.3292.

Authors: Mendonça Gilzelia Cristina Pereira de , Magalhães Júnior Antônio Germano 
Published: February 2022

A política educacional se enquadra no tipo de política majoritária, em que o governo tem responsabilidade e competência em oferecer a todos os brasileiros a educação básica, com acesso, permanência e qualidade, e faz parte dos direitos constitucionais do cidadão brasileiro no artigo 5º da Constituição Federal de 1988. A educação pública tem legislação própria, que determina, diretrizes, funções e seu funcionamento: a LDB n.º 9.394/1996, conjuntamente com o PNE, Lei n.º 13.005/2014, estabelece metas, estratégias e ações para a educação brasileira pelo período determinado de uma década. A formação de professor é uma política pública que busca responder pela qualificação do ensino público e vencer os desafios que permeiam os contextos escolares, fato que compromete a aprendizagem dos alunos, além de promover valorização profissional ao docente. O artigo expressa a correspondência dos objetivos estabelecidos no Programa de Formação Continuada de Professor da Educação Infantil, realizado pela rede pública municipal de Fortaleza no período de 2017 a 2018, investigando os resultados obtidos segundo as narrativas dos sujeitos pesquisados. O programa de formação continuada em 2017 teve por objetivo a reelaboração da proposta pedagógica das instituições públicas municipais de Fortaleza. Em 2018, o objetivo elegeu o fortalecimento do currículo da educação infantil, com a pedagogia de projetos, para promover os direitos de aprendizagem das crianças estabelecidos na BNCC (Brasil, 2017). A pesquisa foi realizada em unidades escolares do Distrito 3, no período de setembro a novembro de 2020. O público-alvo foram professores, coordenadores pedagógicos e técnicos-formadores com atuação na etapa da educação infantil, segmento pré-escola. A literatura pesquisada utilizou de documentos pertinentes a educação pública das esferas: nacional, estadual e municipal. Segundo as narrativas dos sujeitos, foi possível concluir que, em 2017, o objetivo proposto foi alcançado em sua plenitude, mas em 2018, não foi possível lograr de pleno êxito, em virtude dos fatores que envolvem as concepções e os conhecimentos no âmbito do currículo da educação infantil.

IntroductionWe developed a prediction model for atrial fibrillation (AF) progression and tested whether machine learning (ML) could reproduce the prediction power in an independent cohort using pre-procedural non-invasive variables alone.MethodsCohort 1 included 1,214 patients and cohort 2, 658, and all underwent AF catheter ablation (AFCA). AF progression to permanent AF was defined as sustained AF despite repeat AFCA or cardioversion under antiarrhythmic drugs. We developed a risk stratification model for AF progression (STAAR score) and stratified cohort 1 into three groups. We also developed an ML-prediction model to classify three STAAR risk groups without invasive parameters and validated the risk score in cohort 2.ResultsThe STAAR score consisted of a stroke (2 points, p = 0.003), persistent AF (1 point, p = 0.049), left atrial (LA) dimension ≥43 mm (1 point, p = 0.010), LA voltage &lt;1.109 mV (2 points, p = 0.004), and PR interval ≥196 ms (1 point, p = 0.001), based on multivariate Cox analyses, and it had a good discriminative power for progression to permanent AF [area under curve (AUC) 0.796, 95% confidence interval (CI): 0.753–0.838]. The ML prediction model calculated the risk for AF progression without invasive variables and achieved excellent risk stratification: AUC 0.935 for low-risk groups (score = 0), AUC 0.855 for intermediate-risk groups (score 1–3), and AUC 0.965 for high-risk groups (score ≥ 4) in cohort 1. The ML model successfully predicted the high-risk group for AF progression in cohort 2 (log-rank p &lt; 0.001).ConclusionsThe ML-prediction model successfully classified the high-risk patients who will progress to permanent AF after AFCA without invasive variables but has a limited discrimination power for the intermediate-risk group.

ObjectiveThe present study aimed to explore the prognostic value of trimethylamine N-oxide (TMAO) in heart failure (HF).MethodsPubMed, Excerpta Medica Database (EMBASE), Cochrane Library, Web of Science, Wanfang Database, SINOMED, China Science and Technology Journal Database (VIP), and China National Knowledge Infrastructure (CNKI) were searched up to June 1, 2021. Studies recording the major adverse cardiovascular events (MACEs) or all-cause mortality in HF patients and their circulating TMAO concentrations were included. Meta-analysis was performed using Stata 13.0.ResultsTen articles (12 studies) involving 13,425 participants from 2014 to 2021 were considered. Compared to low-level TMAO, elevated TMAO was correlated with MACEs and all-cause mortality in HF (RR: 1.28, 95% CI: 1.17, 1.39, P &lt; 0.0001, random-effects model and RR: 1.35, 95% CI: 1.28, 1.42, P &lt; 0.0001, random-effects model, respectively). Consistent results were obtained in all examined subgroups as well as in the sensitivity analysis.ConclusionElevated TMAO may be an adverse prognostic indicator in patients with HF.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?RecordID=267208

Published: February 2022

ObjectiveAutomated speech recognition (ASR) systems have become increasingly sophisticated, accurate, and deployable on many digital devices, including on a smartphone. This pilot study aims to examine the speech recognition performance of ASR apps using audiological speech tests. In addition, we compare ASR speech recognition performance to normal hearing and hearing impaired listeners and evaluate if standard clinical audiological tests are a meaningful and quick measure of the performance of ASR apps.MethodsFour apps have been tested on a smartphone, respectively AVA, Earfy, Live Transcribe, and Speechy. The Dutch audiological speech tests performed were speech audiometry in quiet (Dutch CNC-test), Digits-in-Noise (DIN)-test with steady-state speech-shaped noise, sentences in quiet and in averaged long-term speech-shaped spectrum noise (Plomp-test). For comparison, the app's ability to transcribe a spoken dialogue (Dutch and English) was tested.ResultsAll apps scored at least 50% phonemes correct on the Dutch CNC-test for a conversational speech intensity level (65 dB SPL) and achieved 90–100% phoneme recognition at higher intensity levels. On the DIN-test, AVA and Live Transcribe had the lowest (best) signal-to-noise ratio +8 dB. The lowest signal-to-noise measured with the Plomp-test was +8 to 9 dB for Earfy (Android) and Live Transcribe (Android). Overall, the word error rate for the dialogue in English (19–34%) was lower (better) than for the Dutch dialogue (25–66%).ConclusionThe performance of the apps was limited on audiological tests that provide little linguistic context or use low signal to noise levels. For Dutch audiological speech tests in quiet, ASR apps performed similarly to a person with a moderate hearing loss. In noise, the ASR apps performed more poorly than most profoundly deaf people using a hearing aid or cochlear implant. Adding new performance metrics including the semantic difference as a function of SNR and reverberation time could help to monitor and further improve ASR performance.
