Fatty Acid Profiles of Selected Microalgae Used as Live Feeds for Shrimp Postlarvae in Vietnam

The importance of microalgal lipids for the survival and growth of shrimp postlarvae has been recognized in a range of studies. Microalgae with fast growth rates and high levels of polyunsaturated fatty acids (PUFA) are considered vital to maximise production and minimise cost in shrimp larviculture. The lipid content and fatty acid composition of microalgae used in shrimp production varies substantially between the algal classes and species being used in Vietnam. This study aims to characterise microalgal lipid and fatty acid (FA) profiles and evaluate the most promising species under growth conditions that are most suitable for shrimp aquaculture. Here, we report that the highest lipid contents were obtained in the Haptophyta microalgae, Tisochrysis lutea and Isochrysis galbana, at 90.3 and 61.1 mg/g, respectively. In contrast, two of the most popular diatom species being used for shrimp larval cultivation in Vietnam, Thalassiosira pseudonana and T. weissflogii, displayed the lowest lipid contents at 16.1 mg/g. Other microalgal species examined showed lipid contents ranging from 28.6 to 55 mg/g. Eicosapentaenoic acid (EPA, 20:5ω3) ranged from 0.6 to 29.9% across the species, with docosahexaenoic acid (DHA, 22:6ω3) present at 0.01 to 11.1%; the two omega (ω)–3 long-chain (LC, ≥C20) LC-PUFA varied between the microalgae groups. Polar lipids were the main lipid class, ranging from 87.2 to 97.3% of total lipids, and triacylglycerol was detected in the range of 0.01 to 2.5%. Saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA) increased and PUFA decreased with increasing growth temperatures. This study demonstrated the differences in the lipid contents and FA profiles across 10 microalgal species and the effect of the higher temperature growing conditions encountered in Vietnam.
INFRARED VARIABILITY OF THE GLIESE 569B SYSTEM

Gliese 569B is a multiple brown dwarf system whose exact nature has been the subject of several investigations over the past few years. Interpretation has partially relied on infrared photometry and spectroscopy of the resolved components of the system. We present seeing-limited Ks photometry over four nights, searching for variability in this young low-mass substellar system. Our photometry is consistent with other reported photometry, and we report the tentative detection of several periodic signals consistent with rotational modulation due to spots on their surfaces. The five significant periods range from 2.90 hr to 12.8 hr, with peak-to-peak variabilities from 28 mmag to 62 mmag in the Ks band. If both components are rotating with the shortest periods, then their rotation axes are not parallel with each other, and the rotation axis of the Bb component is not perpendicular to the Ba–Bb orbital plane. If Bb has one of the longer rotational periods, then the Bb rotation axis is consistent with being parallel to the orbital axis of the Ba–Bb system.
Influence of thermosonication on colour and content of phenolic compounds in red wine

Brettanomyces bruxellensis yeast represents a serious problem in winemaking because it can cause off-odours and mousy off-flavours in red wine, as well as high levels of acetic acid and undesirable colour of wine (1). This can lead to significant reduction of wine quality and economic loss for winemakers. Until now, several different approaches were applied in preventing and controlling B. bruxellensis presence in winemaking (2). One of new approaches is applying non-thermal processing techniques such as high power ultrasound (HPU). HPU induces mechanical, physical and chemical/biochemical changes through cavitation (3). Combining this treatment with mild temperature (thermosonication) could increase microbial inactivation (4) as well as reduce HPU treatment duration, which could prevent the loss of organoleptic qualities of wine such as colour, flavour and taste. The main compounds in red wine that affect organoleptic qualities and also contribute to the complexity and stability of the wine are phenolics (5). Phenolic compounds are also natural antioxidants that could protect human health and it is important to preserve them in wine (6). The aim of this work was to investigate the impact of thermosonication on colour and phenolic compounds content in red wine during its application for inactivation of B. bruxellensis yeast.
The Effect of Different Types of Laryngeal Mask Airways on Sound Quality: A Prospective Randomized Study

Background Although the deterioration in sound quality is not as much as endotracheal intubation, it can also be seen after the use of laryngeal mask airway (LMA). The aim of this study is to investigate the effects of different LMA types on voice performance. Methods This study included 88 patients aged 18-80 years, whose surgical procedure was not planned to take longer than 120 minutes. In the acoustic voice analysis, F0, jitter%, and shimmer% were examined. In addition, the Voice Handicap Index (VHI)-30 questionnaire has completed an evaluation of voice quality. The patients were randomly divided into two groups (I-gel LMA [n=44]; Classic LMA [n=44]) according to the closed envelope method. Results A total of 88 patients were included in the study. Demographic data of the patients were statistically similar between the groups (p > 0.05). The changes in the preoperative and postoperative F0, jitter, and VHI-30 values in the I-gel group were statistically significant (p: 0.002, p: 0.001, p < 0.001). Shimmer values were not significantly different (p: 0.762). In the classical LMA group, preoperative and postoperative F0, jitter, shimmer, and VHI-30 values were statistically significantly different (p: 0.001, p: 0.012, p: 0.036, p < 0.001). Conclusion I-gel LMA and classic LMA negatively affect voice performance in the preoperative and postoperative periods. This situation was also observed in the VHI-30 index test. However, when this situation was evaluated in terms of shimmer analysis, the decrease in voice quality in the early postoperative period was more limited in the I-gel group.
Medical Image Classification based on an Adaptive Size Deep Learning Model

With the rapid development of Artificial Intelligence (AI), deep learning has increasingly become a research hotspot in various fields, such as medical image classification. Traditional deep learning models use Bilinear Interpolation when processing classification tasks of multi-size medical image dataset, which will cause the loss of information of the image, and then affect the classification effect. In response to this problem, this work proposes a solution for an adaptive size deep learning model. First, according to the characteristics of the multi-size medical image dataset, the optimal size set module is proposed in combination with the unpooling process. Next, an adaptive deep learning model module is proposed based on the existing deep learning model. Then, the model is fused with the size fine-tuning module used to process multi-size medical images to obtain a solution of the adaptive size deep learning model. Finally, the proposed solution model is applied to the pneumonia CT medical image dataset. Through experiments, it can be seen that the model has strong robustness, and the classification effect is improved by about 4% compared with traditional algorithms.
Ameliorative Effects of Gallic Acid on Cisplatin-Induced Nephrotoxicity in Rat Variations of Biochemistry, Histopathology, and Gene Expression

Background Cisplatin is a powerful chemotherapeutic drug mainly used in the treatment of solid tumors. Aggregation of the drug in renal proximal tubule cells causes nephrotoxicity and renal failure. Investigations showed nephrotoxicity as Cisplatin's dose-limiting side effect. One of the Cisplatin toxicity mechanisms is generation of reactive oxygen species, which leads to oxidative stress and renal damage. The purpose of this study was evaluation of the modulating effects of Gallic acid on Cisplatin-induced variations including Caspase-3 and Clusterin expression and histopathological and biochemical parameters in adult male Wistar rats. Method Rats were kept under standard condition of temperature, light, and humidity. The animals were divided into 4 groups: GpI: control group (received distilled water for 10 days); GpII: Gallic acid (alone) (50 mg/kg bw, once a day for 10 days); GpIII: Cisplatin (alone), single dose (6 mg/kg bw, I.P. on 5th day of study); GpIV: Gallic acid (50 mg/kg bw, once a day for 10 days) and also injected with single dose of Cisplatin (6 mg/kg bw, I.P., on 5th day of study). After 10 days, all rats were anaesthetized and plasma collected to estimate urea, creatinine, and uric acid. The right kidneys were removed for the study of gene expression and biochemical parameters. The left kidneys were used for histopathological studies. Results The Cisplatin-induced nephrotoxicity was evident from the elevated levels of creatinine, urea, uric acid, and renal tissue MDA and also decreased levels of SOD, CAT, GPX, and GSH in renal tissue. Administration of Gallic acid significantly modulated nephrotoxicity markers, gene expression variations, and histopathological damage. Conclusion Outcomes of the present investigation suggest that Gallic acid provides protection against CP-induced nephrotoxicity, but for application in people, further studies are needed.
Theoretical Study on Metasurfaces for Transverse Magneto-Optical Kerr Effect Enhancement of Ultra-Thin Magnetic Dielectric Films

We study how to enhance the transverse magneto-optical Kerr effect (TMOKE) of ultra-thin magnetic dielectric films through the excitation of strong magnetic resonances on metasurface with a metal nanowire array stacked above a metal substrate with an ultra-thin magnetic dielectric film spacer. The plasmonic hybridizations between the Au nanowires and substrate result in magnetic resonances. The periodic arrangement of the Au nanowires can excite propagating surface plasmon polaritons (SPPs) on the metal surface. When the SPPs and the magnetic resonances hybridize, they can strongly couple to form two strong magnetic resonances, which are explained by a coupled oscillator model. Importantly, benefitting from the strong magnetic resonances, we can achieve a large TMOKE signal up to 26% in the ultra-thin magnetic dielectric film with a thickness of only 30 nm, which may find potential applications in nanophotonics, magnonics, and spintronics.
DEKOLORISASI AIR LIMBAH PENGOLAHAN GURITA MENGGUNAKAN METODE AOT(ADVANCE OXIDATION TREATMENT) DENGAN REAGEN FENTON

ABSTRACT This research aims to determine the effectiveness of Advance Oxidation Treatment (AOT) method with the use of Fenton reagent in decolorization of octopus canning wastewater’s red colour. The use of Fenton reagent (H2O2 and Fe2+) will produce hydroxyl radicals (∙OH) that will oxidize the red colour so the octopus canning wastewater to be colourless and safe to discharged into the environment. Determination of octopus canning wastewater's decolorization is done by determining the change of red color's intensity using Pt/Co scale. The main parameter in determining the decolorization of octopus canning wastewater using Advanced Oxidation Treatment (AOT) with Fenton reagent are time, concentration of Fe2+, concentration of H2O2, and pH. The maximum decolorization of octopus canning wastewater was reached at following condition rarely 55 minutes, with Fe2+ concentration of 42,86 ppm, H2O2 concentration of 85,71 ppm, and pH 4. With a capacity of red color’s decolorization is 49,08 %.

Superlens-enhanced laser interference lithography

A one-step lithography method based on a superlens is proposed to fabricate diffraction-unlimited metallic patterns. By controlling the material parameters and the distribution of the impinging energy, various phenomena, such as periodic nanonetworks, ultrathin nanowires (sub-50-nm feature size), and variable-sized nanoparticles (ranging from sub-10 nm to several hundreds of nanometers), are fabricated using a 1,064-nm nanosecond laser. The evolution pathway of such phenomena is explained by the dewetting process of metallic films. The direct-writing performance of a transparent material with a superlens is studied, and the maximum etching depth of Si gratings can reach 2 µm under a single laser pulse, with fine profiles.
Perovskite Membranes with Vertically Aligned Microchannels for All‐Solid‐State Lithium Batteries

Perovskite‐type solid‐state electrolytes exhibit great potential for the development of all‐solid‐state lithium batteries due to their high Li‐ion conductivity (approaching 10−3 S cm−1), wide potential window, and excellent thermal/chemical stability. However, the large solid–solid interfacial resistance between perovskite electrolytes and electrode materials is still a great challenge that hinders the development of high‐performance all‐solid‐state lithium batteries. In this work, a perovskite‐type Li0.34La0. 51TiO3 (LLTO) membrane with vertically aligned microchannels is constructed by a phase‐inversion method. The 3D vertically aligned microchannel framework membrane enables more effective Li‐ion transport between the cathode and solid‐state electrolyte than a planar LLTO membrane. A significant decrease in the perovskite/cathode interfacial resistance, from 853 to 133 Ω cm2, is observed. It is also demonstrated that full cells utilizing LLTO with vertically aligned microchannels as the electrolyte exhibit a high specific capacity and improved rate performance.
Development of Effective Catalysts for Hydrogen Storage Technology Using Formic Acid

Hydrogen has attracted considerable attention as an energy source, and various attempts to develop suitable methods for hydrogen generation are made at the National Institute of Advanced Industrial Science and Technology. In this paper, the authors introduce their recent strategies to store hydrogen using formic acid (FA) as a hydrogen carrier. FA, which is believed to be one of the most promising liquid organic hydrogen carriers, can provide a viable method for safe hydrogen transportation. In order to optimize the performance of hydrogen storage with FA, the authors have investigated both homogeneous and heterogeneous catalysts. For example, Ir catalysts anchoring N^N‐bidentate ligands show high catalytic activity for both the reactions of FA synthesis and hydrogen generation from FA. Ultrafine Pd‐based nanoparticles are also immobilized on various supports, which show excellent catalytic performance for FA dehydrogenation under mild conditions. The authors also develop both homogeneous and heterogeneous catalysts to generate high‐pressure gases (H2 and CO2) over 120 and 35 MPa, respectively, from direct FA dehydrogenation without any compressing procedures. The generated high‐pressure gases (H2 and CO2) can be easily and simply separated by changing the fluid phase from the supercritical to gas–liquid phase by cooling without depressurization.
Effect of e-liquid from an electronic cigarette on the immune profile of Rana pipiens

Abstract Little is known about the effect of electronic cigarette usage, although the number of people using the devices continues to increase. Here we examine the effect of e-liquid with different concentration levels of nicotine from an electronic cigarette on the immune profile of the northern leopard frog Rana pipiens. Using a Sigelei Mini 30W electronic cigarette, frogs were exposed to vapor for 10 minutes, 6 days a week, for 3 weeks. We hypothesized that e-liquid vapor would alter the leukocyte differentials and positively correlate with the nicotine concentration. Our results indicate mean lymphocyte percent decreased with both vapor exposures without nicotine (24.8 ± 0.0% in control vs. 6.0 ± 1.2%) and with nicotine (24.8 ± 0.0% in control vs. 5.8 ± 4.0%), whereas the mean neutrophil percent increased with vapor without nicotine (60.8 ± 0.0% in control vs. 89.4 ± 3.0%) and with nicotine (60.8 ± 0.0% in control vs. 90.3 ± 6.0%). There was a significant positive correlation between vapor exposure and total neutrophil differentials (r = 0.954, p < 0.01). However, there was no positive correlation between the nicotine concentration and lymphocyte differentials (r = 0.83; p > 0.05). Monocyte, basophil, and eosinophil percentages also decreased in frogs that were exposed to vapor. These findings suggest that electronic cigarette smoke alters the immune profile of frogs with or without nicotine.
Quantification by LC-MS/MS of individual sugars in fruit juice consumed in Portugal

To address the sugar contents in fruit juices, consumed in Portugal, a mass spectrometer coupled to a liquid chromatographer (UPLC-MS/MS) method was developed and optimized. The method offers good sensitivity and excellent linearity with a correlation coefficient above 0.995. The optimized method was applied to the analysis of fruit juice in terms of their sucrose, fructose and glucose content. The highest content of total sugars was found in red berries juice and pear juice, in contrast with multi-fruit juice. The results were lower than those previously published in the Portuguese Food Composition Table, indicating that the national campaign, presently in course, to reduce the amount of sugar in beverages is effective.
DGS Loaded Broadband Circular Patch Antenna for Satellite Communications

Broadband slotted circular patch antenna with Defective Ground Structure intended for Ku band satellite communications is presented in this communication. The proposed antenna has a fundamental circular radiating element in which a square ring slot is etched along with a circular slot inside it. The ground is etched with a rhombus ring slot at the center and square slots in the corners. The defective ground provides multiple frequencies of operation and the slots in the radiating element act as filters combining the multiple frequencies of operation into broadband. The antenna is fabricated on an FR4 substrate with a volume of 40mm×48mm×1.59mm and a dielectric constant of 4.4. The antenna has been excited using a stripline feed of 50Ω impedance. The proposed antenna has an impedance bandwidth of 1.87GHz ranging from 13.61GHz to 15.48GHz with gain and directivity of 2.2dB and 6.09dB at 13.84GHz, 2.8dB and 5.47dB at 14.48GHz, respectively. The simulated and measured antenna results are in good agreement, showing that the proposed techniques enhance the antenna bandwidth.
PARENTAL PERCEPTIONS OF LEARNING LOSS DURING COVID-19 SCHOOL CLOSURES IN 2020

ABSTRACT Schools across the UK were mostly closed from March to July 2020 due to Covid-19. Therefore, parents and children found themselves thrust into a prolonged period of home-schooling. In this study, parents (N = 2,122) reported on their children’s (N = 3,230) home-schooling experiences and its impacts on their children’s academic progress. Parental reports suggest that children spent around 3 hours each weekday doing schoolwork at home. Children enrolled in private secondary schools received 4 hours of virtual lessons each weekday from teachers, while state school children received just 1 hour. Parents, on the whole, reported concern for children’s academic progress. This is particularly so for children in secondary school and, most strikingly, those in school years antecedent to final exams (Years 10 and 12). Parents were less concerned about academic progress for those in Years 11 and 13, who had received their final exam grades shortly before the time of the survey. This study highlights the fact that children have been unequally affected by Covid-19 school closures, depending on their year group and school type, which should be considered in future research and policy.
Agreement between heart rate at first ventilatory threshold on treadmill and at 6-min walk test in coronary artery disease patients on β-blockers treatment

The purpose of this study was to verify the accuracy of the agreement between heart rate at the first ventilatory threshold (HRVT1) and heart rate at the end of the 6-min walk test (HR6MWT) in coronary artery disease (CAD) patients on β-blockers treatment. This was a cross-sectional study with stable CAD patients, which performed a cardiopulmonary exercise test (CPET) on a treadmill and a 6-min walk test (6MWT) on nonconsecutive days. The accuracy of agreement between HRVT1 and HR6MWT was evaluated by Bland–Altman analysis and Lin’s concordance correlation coefficient (rc), mean absolute percentage error (MAPE), and standard error of estimate (SEE). Seventeen stable CAD patients on β-blockers treatment (male, 64.7%; age, 61±10 years) were included in data analysis. The Bland–Altman analysis revealed a negative bias of −0.41±6.4 bpm (95% limits of agreements, −13 to 12.2 bpm) between HRVT1 and HR6MWT. There was acceptable agreement between HRVT1 and HR6MWT (rc=0.84; 95% confidence interval, 0.63 to 0.93; study power analysis=0.79). The MAPE of the HR6MWT was 5.1% and SEE was 6.6 bpm. The ratio HRVT1/HRpeak and HR6MWT/HRpeak from CPET were not significantly different (81%±5% vs. 81%±6%, P=0.85); respectively. There was a high correlation between HRVT1 and HR6MWT (r=0.85, P<0.0001). Finally, the results of the present study demonstrate that there was an acceptable agreement between HRVT1 and HR6MWT in CAD patients on β-blockers treatment and suggest that HR6MWT may be useful to prescribe and control aerobic exercise intensity in cardiac rehabilitation programs.
Mn 3 O 4 Nanosheet and GNS– Mn 3 O 4 Composite as High-Performance Anode Materials for Lithium-Ion Batteries

Nanostructured transitional metal oxides have received more and more attention as the electrode materials for lithium-ion batteries to achieve high speciﬁc capacity and good safety performance. In this paper, a graphene nanosheet-supported Mn 3 O 4 nanoparticles (Mn 3 O 4 –GNS) composite, as well as Mn 3 O 4 nanosheet, were synthesized via a facile hydrothermal method. The Mn 3 O 4 –GNS composite exhibits good electrochemical performances with high reversible speciﬁc capacity (an initial charge capacity of 969mAh g − 1 at 93.6mAg − 1 ), good cycling stability (a retained capacity of 646mAh g − 1 after 60 cycles) and rate capability when used as the anode material for LIBs. The enhanced electrochemical performance could be attributed to the nanoscaled particles of Mn 3 O 4 , the buffer and conﬁne effects of graphene nanosheets (GNSs) and the distinctive synergisticeffectbetweentwocomponentsofGNSandmetal oxides.
