Sweet potato (Ipomoea batatas L.) is a root that allows healthy eating and combats malnutrition. There is a need for more productive sweet potato genotypes displaying good resistance and a favorable appearance and shape. New genotypes that are more productive, resistant to the main soil pests and with good physical characteristics would contribute to meet the needs of producers and the demands of consumers. The aim of this study was to develop and select sweet potato genotypes regarding agronomic and physical root parameters. The new genotypes were obtained through the cross-linking of 22 parents with commercial characteristics. Subsequently, 386 experimental genotypes were conducted in the feld in an experimental design consisting of augmented blocks with intercalated controls. Aspects related to agronomic, physical root characteristics and resistance to Euscepes postfasciatus were explored. Genotypes with higher performance than the controls were identifed for all assessed parameters. The genotypes UZBD-K-09, UZBD-K-56 and UZBD-K-78, with purple fesh roots, UZBD-F-15 and UZBD-F-34, with orange fesh, and UZBD-K-70, with a white fesh were selected.
tufA gene as molecular marker for freshwater Chlorophyceae
Helena Henriques Vieira,Inessa Lacativa Bagatini,Carla Marques Guinart,Armando Augusto Henriques Vieira 한국조류학회I 2016 ALGAE Vol.31 No.2
Green microalgae from the class Chlorophyceae represent a major biodiversity component of eukaryotic algae in continental water. Identification and classification of this group through morphology is a hard task, since it may present cryptic species and phenotypic plasticity. Despite the increasing use of molecular methods for identification of microorganisms, no single standard barcode marker is yet established for this important group of green microalgae. Some available studies present results with a limited number of chlorophycean genera or using markers that require many different primers for different groups within the class. Thus, we aimed to find a single marker easily amplified and with wide coverage within Chlorophyceae using only one pair of primers. Here, we tested the universality of primers for different genes (tufA, ITS, rbcL, and UCP4) in 22 strains, comprising 18 different species from different orders of Chlorophyceae. The ITS primers sequenced only 3 strains and the UCP primer failed to amplify any strain. We tested two pairs of primers for rbcL and the best pair provided sequences for 10 strains whereas the second one provided sequences for only 7 strains. The pair of primers for the tufA gene presented good results for Chlorophyceae, successfully sequencing 21 strains and recovering the expected phylogeny relationships within the class. Thus, the tufA marker stands out as a good choice to be used as molecular marker for the class.

Can a spontaneous smile invalidate facial identification by photo-anthropometry?
Pinto, Paulo Henrique Viana,Rodrigues, Caio Henrique Pinke,Rozatto, Juliana Rodrigues,da Silva, Ana Maria Bettoni Rodrigues,Bruni, Aline Thais,da Silva, Marco Antonio Moreira Rodrigues,da Silva, Ricar Korean Academy of Oral and Maxillofacial Radiology 2021 Imaging Science in Dentistry Vol.51 No.3
Purpose: Using images in the facial image comparison process poses a challenge for forensic experts due to limitations such as the presence of facial expressions. The aims of this study were to analyze how morphometric changes in the face during a spontaneous smile influence the facial image comparison process and to evaluate the reproducibility of measurements obtained by digital stereophotogrammetry in these situations. Materials and Methods: Three examiners used digital stereophotogrammetry to obtain 3-dimensional images of the faces of 10 female participants(aged between 23 and 45 years). Photographs of the participants' faces were captured with their faces at rest (group 1) and with a spontaneous smile (group 2), resulting in a total of 60 3-dimensional images. The digital stereophotogrammetry device obtained the images with a 3.5-ms capture time, which prevented undesirable movements of the participants. Linear measurements between facial landmarks were made, in units of millimeters, and the data were subjected to multivariate and univariate statistical analyses using Pirouette<sup>®</sup> version 4.5 (InfoMetrix Inc., Woodinville, WA, USA) and Microsoft Excel<sup>®</sup> (Microsoft Corp., Redmond, WA, USA), respectively. Results: The measurements that most strongly influenced the separation of the groups were related to the labial/buccal region. In general, the data showed low standard deviations, which differed by less than 10% from the measured mean values, demonstrating that the digital stereophotogrammetry technique was reproducible. Conclusion: The impact of spontaneous smiles on the facial image comparison process should be considered, and digital stereophotogrammetry provided good reproducibility.

OBJECTIVES: To evaluate the effectiveness of hydrogen peroxide (H2O2) in the form of mouthwash and nasal spray as an auxiliary treatment for coronavirus disease 2019 (COVID-19). METHODS: Forty hospitalized patients who tested positive for severe acute respiratory syndrome coronavirus 2 using a reverse-transcription polymerase chain reaction test were evaluated. They were randomly divided into an experimental group (n=20; gargling with 1.0% H2O2 and nasal wash with 0.5% H2O2) or a control group (n=20). The solutions were used for 7 days and the patients were monitored every 2 days, for a total of 8 days. At check-ups, patients were asked about their symptoms and possible adverse effects of the solutions. The presence and severity (mild, moderate, or severe) of symptoms were recorded. Data were compared using the Student test and the Fisher exact test (α=0.05). RESULTS: There was no significant difference between the 2 groups in the length of hospital stay (p=0.65). The most frequent symptom on day 0 was coughing (72.0% in the experimental group and 76.5% in the control group), which abated over time. There was no significant difference between the groups in the evaluated symptoms. Most (75.0%) of the patients in the experimental group presented a reduction in dyspnea between days 0 and 2. Few patients reported adverse effects from the use of the solutions. CONCLUSIONS: H2O2 as a mouthwash and nasal spray is safe to use. There is insufficient evidence to demonstrate that H2O2 is effective as an auxiliary treatment for hospitalized COVID-19 patients.

OBJECTIVES: This study evaluated the effectiveness of hydrogen peroxide (H2O2) as mouthwash and nasal spray on symptom relief in coronavirus disease 2019 (COVID-19) patients. METHODS: Patients positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), who were treated in a hos-pital or at home, and patients’ family members (not positive for SARS-CoV-2), were randomized into 2 groups: experimental (1% H2O2 for gargling, 0.5% H2O2 for nasal wash), and control. Patients gargled the solution 3 times a day, and applied the nasal spray twice a day, for a 7-day period. Family members received the same treatment as the treated COVID-19 patient. The re-searchers contacted patients every 2 days over an 8-day period. An average post-treatment interval of 8 days passed before test-ing family members. RESULTS: The most frequent symptoms on day 0 were cough, loss of taste, and hyposmia; there were no significant differences between groups, independent of the period. The symptom of dyspnea presented a significant difference between days 2 and 4 (p< 0.05). Among family members, 86.0% had no antibodies, 2.3% had antibodies, and 11.6% had active infections (4 in the ex-perimental group and 6 in the control group). The most frequent adverse effects in the H2O2 group were a burning throat and nose. CONCLUSIONS: H2O2 was not effective for the relief of COVID-19 symptoms and was associated with reports of transient adverse effects.
Rigidity theorems in the hyperbolic space
Henrique Fernandes de Lima 대한수학회 2013 대한수학회보 Vol.50 No.1
As a suitable application of the well known generalized max- imum principle of Omori-Yau, we obtain rigidity results concerning to a complete hypersurface immersed with bounded mean curvature in the (n+ 1)-dimensional hyperbolic space Hn+1. In our approach, we explore the existence of a natural duality between Hn+1 and the half Hn+1 of the de Sitter space Sn+1 1 , which models the so-called steady state space.
A note on maximal hypersurfaces in a generalized Robertson-Walker spacetime
Henrique Fernandes de Lima 대한수학회 2022 대한수학회논문집 Vol.37 No.3
In this note, we apply a maximum principle related to vo\-lu\-me growth of a complete noncompact Riemannian manifold, which was recently obtained by Al\'{\i}as, Caminha and do Nascimento in~\cite{Alias-Caminha-Nascimento}, to es\-ta\-blish new uniqueness and nonexistence results concerning maximal spacelike hypersurfaces immersed in a generalized Robertson-Walker (GRW) spacetime obeying the timelike convergence condition. A study of entire solutions for the maximal hypersurface equation in GRW spacetimes is also made and, in particular, a new Calabi-Bernstein type result is presented.

An experimental and numerical assessment of multilayer active magnetic regenerators (AMR) composed of gadolinium (Gd) and gadolinium–yttrium (Gd–Y) alloys (Gd 97.34 Y 2.66, Gd 95.98Y 4.02 and Gd 94.79Y 5.21) is presented. First, by calculating the adiabatic temperature change and the isothermal entropy change from the experimental data for the above materials, we show that, with reasonable accuracy for engineering design purposes, these properties can be determined by shifting the properties of pure Gd to the Curie temperature of the Gd–Y alloy — a common but not yet validated assumption in the design of Gd–Y AMRs with a low Y content. Next, we show that the optimal Gd–Y layer fraction in multilayer AMRs can be determined using the figure of merit known as the material refrigerant capacity (RC), which agrees well with the results from a more complex one-dimensional thermal non-equilibrium porous medium AMR model. Finally, the performance of the latter model is verified against the experimental cooling power data for two- and three-layer Gd–Y regenerators at temperature spans of 25, 30 and 35 K.
