title: CAN ACCURACY ISSUES OF LOW-COST SENSOR MEASUREMENTS BE OVERCOME WITH DATA ASSIMILATION?

description: ABSTRACT The use of mechanistic plant growth models relies on the availability of high-quality inputs to reduce uncertainty in estimates. Measurements of photosynthetically active radiation inside a protected environment are either more expensive to obtain or dependent on assumptions regarding external measurements. This study aimed to reduce the influence of uncertainty in the measurements of low-cost lux meters by using a data assimilation strategy. We first determined, by simulation, the impact of different sensors on the estimates. We then used the Ensemble Kalman Filter to assimilate artificial observations of tomato growth in the Reduced-State Tomgro model, in simulations for which the solar radiation inputs were obtained from a low-cost lux meter. We compared the assimilated estimates to the simulations that used solar radiation obtained with a scientific-grade quantum sensor. For periods of larger radiation intensity, in which the differences in measurements from both instruments are larger, assimilation of observations with low errors lead to estimates that are closer to the ones obtained by scientific grade sensors. These results suggest that low-cost sensors could be used to obtain inputs for growth models in protected environments, provided there are also imperfect observations of the state.

title: Influence of solvent choice and operating conditions on Chlorzoxazone crystal shape and size

description: Abstract Solubility of pharmaceutical drugs in organic solvents is one of the important parameters to understand the equilibrium concentration of solute-solvent, which helps optimize and design crystallization conditions to obtain the desired product crystals. In the present study, Chlorzoxazone (CHZ) is used as a model pharmaceutical compound to investigate the equilibrium solubility, the influence of solvent and the operating conditions on the shape, and the size distribution. The solubility of CHZ is determined in organic solvents like Isopropanol, Ethanol, and 2-Ethoxyethylacetate, Ethylacetate and Ethyllactate using shake flask method from -5ºC to 60ºC. The solubility of CHZ in these solvents shows an increasing trend as the temperature increases in the following order: ethyllactate + water (0.5+0.5) &lt; ethylacetate &lt; isopropanol &lt; ethanol &lt; 2-ethoxyethylacetate &lt; ethyllactate + water (0.75+0.25). The solvents, isopropanol, ethanol, and ethyl lactate, produce needle-shaped crystals, while 2-ethoxyethylacetate and ethyl acetate tend to produce plate shaped crystals. CHZ crystals obtained from 2-ethoxyethylacetate tend to have plate shaped crystals with a lower aspect ratio and are selected for batch cooling crystallization experiments performed at different cooling rates, and agitation. It is found that the agitation at 300 rpm and the cooling rate 0.2ºC/min produce more uniform crystal size distribution.

title: Edge level of aligners and periodontal health: a clinical perspective study in young patients

description: ABSTRACT Introduction: Although the superiority of clear aligners over multi-bracket appliances in keeping gingiva healthy has been suggested, the possible benefits of one aligner design over another have not yet been investigated, especially with regard to the vestibular edge. Objective: The aim of this study was to measure several periodontal indexes in adolescents undergoing orthodontic treatment with aligners, comparing two different types of rim. Methods: The study involved 43 patients aged between 14 and 18 years. The periodontal health was assessed using plaque index (PI), gingival index (GI), and gingival bleeding index (GBI), at the start of the treatment with aligners (T0), with a vestibular rim (VR) reaching up to 3 mm beyond the gingival margin. Three months later (T1), aligners were set to obtain a juxtagingival rim (JR) on the second quadrant and VR on the first quadrant. The periodontal indexes were measured again, both at T1 and then three months later (T2). Results: Intra-quadrant comparisons revealed a statistically significant worsening of the periodontal indexes only for the second quadrant (p&lt;0.05), at T1 (GI), and especially at T2 (PI, GI, GBI), while no statistically significant changes were found for the first quadrant. Conclusions: More severe mechanical irritation, especially during insertion and removal of the aligner, can explain the worsening inflammatory indexes with the JR. In addition, the pressure exerted by the JR on the gingival sulcus seemed to facilitate plaque deposition, whereas the VR had a protective effect, reducing the risk of mechanical trauma.

title: Effects of the Math Anxiety of Parents and Teachers on Students

description: Abstract The aim of the study was to demonstrate a relationship between the math anxiety (MA) of parents and teachers and the MA of children and the effects on the children’s performance in arithmetic. 286 children aged between 7 and 10 years and their parents and mathematics teachers participated in the study. The instruments used were: Math Anxiety Questionnaire; School Performance Test - Arithmetic subtest; Mathematical Anxiety Scale; and Raven’s Colored Progressive Matrices. The results showed that advanced age of the teacher was a predictor of high levels of MA, which influenced the children’s performance in arithmetic. Low parental education was associated with high MA, however, there were no correlations between parents’ and children’s MA. A significant difference was found between the MA mean scores for girls and boys, with the girls presenting higher levels of MA.

title: Lantana flowering at an indoor active living wall in a light-restricted environment

description: ABSTRACT: The time spent by urban residents indoors has been increasing annually, thus, prioritizing the enhancement of indoor spaces into green spaces to improve the quality of life. Even with limited environmental conditions indoors, an active living wall and LED light techniques have enabled us to explore indoor green environments. In the present study, the yellow/orange-colored flowers invasive ornamental species,Lantana camara‘splendens’, was cultivated in 4.0 m2 of the active living wall under a non-decorative LED lamp, adjusted to optimize performance in the coverage area. This study evaluated the development of lantana in the active living wall under different light intensities (135 watts and 90 watts) in a room with light restriction. Parameters such as plant height, flowering, SPAD chlorophyll content, and vegetative cover were analyzed. The results indicated that Lantana camara ‘splendens’ is suitable for use in active living walls and blooms at a low light intensity when the light is uniformly applied.

title: Consumption of alcoholic beverages in Brazil: estimation of prevalence ratios – 2013 and 2019

description: ABSTRACT OBJECTIVES To estimate the prevalence of weekly, monthly and abusive alcohol consumption in Brazil in 2013 and 2019, compare the period estimates, and verify the magnitude of the differences. METHODS Analysis of data on alcohol consumption in the adult population (18 years or older) from the National Health Survey (PNS), 2013 and 2019. The number of interviewees in 2013 was 60,202 and 88,531 in 2019. The samples were characterized according to demographic, socioeconomic, health, and alcohol consumption variables and differences in proportions in the period were compared using Pearson’s c2 test, with Rao-Scott approximation and a 5% significance level. Multivariate Poisson regression models were estimated for the outcome variables of monthly, weekly and abusive consumption of alcoholic beverages, in order to estimate the magnitude of the differences between the 2013 and 2019 PNS estimates, using the prevalence ratio (PR). Models were adjusted per sex and age group and stratified per sex and demographic region. RESULTS There was a difference in the distribution of the population according to race, occupation, income, age group, marital status, and education. There was an increase in alcohol consumption for all outcome variables, with the exception of weekly consumption in males. The PR of weekly consumption was 1.02 (95%CI 1.014–1.026), and in females the PR was 1.05 (95%CI 1.04–1.06). The highest PRs in the general population and per sex occur for abusive consumption. The increase in weekly consumption per region occurred in the South, Southeast, and Central-West regions. CONCLUSIONS Males are the main alcohol consumers in Brazil; the PRs for both males and females show that there was an increase in monthly, weekly and abusive consumption in the research period; it is noteworthy that females have increased their consumption pattern with greater intensity than males.

title: Assessing morbidity, mortality, and survival in patients with peritoneal carcinomatosis undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy

description: ABSTRACT Peritoneal carcinomatosis (PC) indicates advanced stage cancer, which is generally associated with a poor outcome and a 6 to 12 months. Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is an option for treating patients with primary PC, such as mesothelioma, or secondary PC, such as colorectal cancer (CRC) or pseudomixoma. Until recently, such patients were deemed untreatable. Objective: The purpose of this study was to assess the results of CRS + HIPEC in patients with PC. Postoperative complications, mortality and survival rates were evaluated according to the diagnosis. Results: Fifty-six patients with PC, undergoing full CRS + HIPEC between October 2004 and January 2020, were enrolled. The mortality rate was 3.8% and the morbidity rate was 61.5%. Complications were significantly higher in proportion to the duration of surgery (p&lt;0.001). The overall survival rates, as shown in the Kaplan-Meyer curve, were respectively 81%, 74% and 53% at 12, 24 and 60 months. Survival rates according to each diagnosis for the same periods were 87%, 82% and 47% in patients with pseudomixoma, and 77%, 72% and 57% in patients with CRC (log-rank 0.371, p=0.543). Conclusion: CRS with HIPEC is an option for pacients with primary or secondary PC. Although complication rates are high, a longer survival rate may be attained compared to those seen in previously published results; in some cases, patients may even be cured.

title: Clinico-pathological and immunohistochemical findings in a case of bovine cutaneous angiomatosis in a Holstein heifer

description: ABSTRACT: Bovine cutaneous angiomatosis (BCA) is a rare condition characterized by vasoproliferative skin lesions mainly affecting cattle in the northern hemisphere. An eight-month-old Holstein heifer showed two skin easy-bleeding nodules bulging from the epidermis in the forehead and close to the right prescapular region. Skin lesions were within the dermis and had an irregular surface and a soft heterogeneous reddish parenchyma composed of numerous variable-sized arterioles, veins, and capillaries surrounded by abundant collagenous fibrous tissue. Immunohistochemical assays evidenced endothelial cells lining proliferative vascular structure immunolabeled for CD31 and Von Willebrand factor, and vascular smooth muscle cells immunostained for smooth muscle actin. All clinical, pathological, and immunohistochemical features observed in the Holstein heifer were hallmarks of BCA. Considering its potential for hereditary spread, BCA must be included in the differential diagnosis of easily bleeding skin nodules that do not respond to routine topical wound treatments to prevent its spread in Brazilian herds.

title: CULTIVATION OF XARAÉS GRASS IRRIGATED WITH IRON MINING TAILINGS

description: ABSTRACT The collapse of the Fundão dam in Brazil caused one of the biggest environmental disasters. One of the challenges was how to manage the tailings so that affected areas could be reused. This study aimed to verify whether applying different irrigation depths to Xaraés grass grown with iron mining tailings would affect grass shoot and root dry masses. The experiment was set up in a randomized design with five irrigation depths (40%, 60%, 80%, 100%, and 120% of crop evapotranspiration) and two additional treatments (grass grown in tailings with soil conditioner, and grass grown in natural soil), each with three repetitions. The grass was cut four times, and the shoot dry mass was evaluated after each cut, while the root dry mass was evaluated at the end of the experiment. Our results showed that irrigation depths had a positive linear effect on shoot dry mass and an exponentially increasing effect on root dry mass, with the highest averages in the treatment applying 120% of crop evapotranspiration. This study showed that even in adverse conditions, Xaraés grass was able to grow and develop well.
