Production and diversity of microorganisms associated with sinking particles in the subtropical North Pacific Ocean

Sinking particulate organic matter controls the flux of carbon (C) from the surface ocean to the deep sea. Microorganisms actively colonize particles, but the extent to which microbial metabolism influences particle export remains uncertain. We conducted experiments to quantify rates of bacterial production (derived based on 3H‐leucine incorporation) and dark C‐fixation (based on 14C‐bicarbonate assimilation) associated with sinking particles collected from the base of the euphotic zone (175 m) in the subtropical North Pacific Ocean. Seawater was amended with sinking particles and rates of filter size‐fractionated (0.2, 2, and 20 μm) bacterial production and dark C‐fixation were measured. Sequencing of 16S ribosomal RNA (rRNA) gene amplicons revealed that microorganisms in the particle‐amended treatments differed from those in the unamended seawater controls, with the particle treatments enriched in putative copiotrophic bacteria. The addition of sinking particles increased rates of bacterial production (by 6‐ to 9‐fold), and to a lesser extent dark C‐fixation (by 1.7‐ to 4.6‐fold), relative to unamended controls, with most of the production associated with filter pore sizes < 20 μm. Normalizing production to concentrations of particulate C yielded rates that were statistically indistinguishable between particle‐amended treatments and unamended controls. We then examined possible relationships between sinking particulate C flux attenuation and its supply to the mesopelagic waters, revealing that flux attenuation was positively related to increases in particulate C supply. Together with results from our experiments, we suggest processes that contribute to sinking particle disaggregation both increase flux attenuation and favor microbial mineralization of particle‐derived organic matter.
High-Spatial-Resolution Strain Sensor Based on Distance Compensation and Image Wavelet Denoising Method in OFDR

A high-spatial-resolution strain sensor in OFDR was experimentally demonstrated by use of combining distance compensation (DC) and image wavelet denoising (IWD) method. Compared with using one method alone, the measured distribution strain could be varied from 200 to 2000 μϵ at a spatial resolution of 2.56 mm. Moreover, four times enhancement of the accuracy for the strain senor was achieved without hardware modification. This method is a significant step toward a high performance OFDR system, especially for evaluating the rapid change of object's structural condition.

High School Jazz Band Directors’ Efficacious Sources, Self-Efficacy for Teaching Strategies, and Pedagogical Behaviors

The purpose of this study was to examine relationships between high school jazz band directors’ efficacious sources, self-efficacy for teaching strategies, and pedagogical behaviors. Participants (N = 264) completed the Jazz Band Director Self-Efficacy for Teaching Strategies Scale and responded to items about their formal and informal learning experiences, school characteristics, and demographics. Parental support was the best predictor of participants’ self-efficacy for jazz teaching strategies, followed by undergraduate participation in jazz performance and improvisation courses, school enrollment, and completing a doctorate or master’s degree. Participants with greater scores on self-efficacy for teaching strategies also indicted greater comfort for teaching various styles commonly performed by high school jazz bands and dedicated more class time to teaching improvisation and jazz theory. Jazz directors may improve their self-efficacy for teaching strategies by developing parental trust and engagement with the jazz program and seeking feedback from effective mentors when refining jazz teaching strategies.
Clay mineralogy of soils from lower atrai basin of Bangladesh

The lower Atrai basin, the study area, lies in the Agroecological Zone-5 (AEZ-5) of Bangladesh. This study reveals the clay mineral composition of top soils of seven different soil series viz. Binsara, Taras, Jaonia, Hasnabad, Laskara, Manda and Mainam developed in the basin. X-ray diffraction (XRD) technique was employed to identify and quantify the minerals. Results show that mica (41 to 59%) was the most dominant mineral among all soils except Laskara. In Laskara soils, the interstratified mica-vermiculite-smectite (41%) was the predominant mineral. Next to mica, kaolinite (10 to 12%) was found to be present in the Binsara, Taras 1, Jaonia, and Taras 2 soils. Chlorite (7 to 17%) was identified in all the soils and was found to be the second dominant mineral in the Manda and Mainam soils. In contrast, the interstratified mica-vermiculitesmectite (33%) was found to be the second dominant mineral in the Hasnabad soils. Small amounts of vermiculite mineral (1 to 13%) were identified in almost all the soils except Binsara. All the soils have interstratified mica-chlorite minerals (2 to 7%). A tiny amount of smectite (1%) was identified in Taras 1 soil. As far as the clay mineralogical composition is concerned, most studied soils were found at the initial stage of weathering, indicating the high potential to sustain low input subsistence agriculture.

Attenuation of salt stress on the physiology and production of bell peppers by treatment with salicylic acid

The use of saline water for irrigation in semi-arid regions has become a reality due to the water scarcity that occurs in most of the year. In this scenario, exogenous application of salicylic acid may be a strategy to mitigate the deleterious effects of salt stress on plants and ensure the production of socioeconomically important crops in the semiarid region of Northeast Brazil, such as bell pepper. Thus, this study examines the osmoprotective effect of salicylic acid on gas exchanges, chloroplast pigments and production components of ‘All Big’ bell pepper plants irrigated with water with different saline levels. The experiment was carried out in greenhouse conditions in Campina Grande - PB, Brazil. Treatments consisted of four levels of electrical conductivity on the irrigation water (0.8, 1.6, 2.4 and 3.2 dS m-1) and four concentrations of salicylic acid (0, 1.2, 2.4 and 3.6 mM), which were distributed in a 4 × 4 factorial arrangement in a randomized block design with three replicates. Increases in irrigation water salinity from 0.8 dS m-1 resulted in changes in gas exchange and total chlorophyll levels of ‘All Big’ bell pepper plants. The estimated salicylic acid concentration of 1.7 mM reduced the effects of salinity on stomatal conductance, transpiration, CO2 assimilation rate, instantaneous carboxylation efficiency, total chlorophyll and fruit diameters. Irrigation with water of 1.8, 0.8 and 1.6 dS m-1 salinity associated with the estimated salicylic acid concentration of 1.6 mM increased the biosynthesis of chlorophylls a and b and the number of fruits, respectively, in bell pepper plants.
Digital Education to improve the Quality of Human Resources Implementing Digital Transformation in the Context of Industrial Revolution 4.0

Digital economy has become a new direction with lots of potentials for the world economy as well as Vietnam. Digital transformation is the process in which people change the way people live, work, and produce with digital technologies. To do that, it is necessary to make a change in both management methods and practical teaching in universities. That is, universities must apply modern information technology to meet the increasing learning needs of students and faculty, creating a learning environment where everything is connected. This is an ecosystem that combines technology, services and security to bridge the digital divide. That will create collaborative, interactive, and personalized learning experiences. Digital transformation is the transition from a traditional way of living, working to a way of living and working with both digital versions of entities and their connections in digital spaces. The study aims to analyze the need for the formation of a digital economy training field to create high-quality human resources to operate in the digital economy environment. Research uses a combination of qualitative research methods and quantitative research. In particular, qualitative research using in-depth interview method for experts including leaders, managers at universities, business managers. The aim is to explore the influencing aspects of the industrial revolution 4.0 on the human resource training process to respond to businesses in the digital transformation landscape.

Highly Efficient Sorption of Methyl Orange by a Metal-Organic Resin-Alginic Acid Composite.

The composite anion-exchange material MOR-1-HA (metal-organic resin-1-alginic acid) was investigated as sorbent for the capture of the methyl orange anion (MO- ) from aqueous solutions. MOR-1-HA shows a remarkably high sorption capacity (up to 859 mg g-1 ) and rapid sorption kinetics, the fastest among the reported metal-organic sorbents. It is capable of absorbing MO- over a wide pH range (1-8) and, in addition, it exhibits significant MO- sorption affinity even in the presence of large excesses of competing anions (e.g., Cl- , NO3 - , SO4 2- ). The exceptional MO- -sorption properties of MOR-1-HA arise not only from its highly porous structure and easily exchangeable Cl- anions, but also from a multitude of interaction effects, such as electrostatic interactions between MO- and the NH3 + groups of the material, hydration/dehydration, hydrophobicity/hydrophilicity, size and capacity of generating lateral interactions, and intercalation as revealed by theoretical studies. An ion-exchange column with a stationary phase containing MOR-1-HA and silica sand showed high efficiency for the removal of MO- from various types of aqueous samples. The column can be readily regenerated and reused for many runs with minimal loss (2.3-9.3 %) of its exchange capacity. The simplicity of the MOR-1-HA/sand column and its high regeneration capability and reusability make it particularly attractive for application in the remediation of MO- -contaminated industrial wastewater.
Soft-Safe: Software Defined Safety-as-a-Service for Intelligent Transportation System

In this work, we propose Soft-Safe, a Software Defined Safety-as-a-Service (Safe-aaS) model for provisioning safety-related decisions to the registered end-users. In Safe-aaS, the end-users register to the infrastructure, provide their initial and destination location, select certain decision parameters, and make payment through a Web portal. As the safety-related decisions are time-critical in nature, therefore timely delivery of these decisions is essential. Considering these facts and road transportation as the application scenario of Safe-aaS, we address the problem of efficient decision delivery to the end-users in two stages. In the first stage, we propose a Software Defined Safe-aaS platform to address the problems of heterogeneity among the SDN switches present in the edge layer. Further, based on the utility of each of the SDN switches present within the vicinity of the end-users, we optimally select a suitable SDN switch among the available ones, for delivering them decisions in the second stage. To obtain the maximum utility for delivering decisions to the end-users, we map the interactions between the SDN controller and SDN switches as a Non-cooperative Single Leader Multiple Follower game. Then, we estimate the optimal delay incurred by an SDN switch applying the Lagrangian function and Karush-Kuhn-Tucker (KKT) conditions. Exhaustive simulation results illustrate that the energy consumed and delay incurred using our proposed scheme, Soft-Safe, is reduced compared to the existing schemes, Traditional Safe-aaS and MoRule.
The Effects of Different Rates of Chicken Manure and Harvest Intervals on the Bioactive Compounds of Bitter Leaf (Vernonia amygdalina Del.)

Bitter leaf (Vernonia amygdalina Del.) is a valuable functional vegetable and traditional medicinal plant in many tropical countries including Indonesia. Bitter leaf is commonly used to remedy hypertension and diabetes among Indonesian people. The leaf extract comprises bioactive compounds such as sesquiterpene lactones, steroid glycosides, and flavonoids. Despite its growing market demand, there is insufficient data on agronomic practice in order to obtain optimum yield with high bioactive compounds. The experimental design used was a randomized complete block design with two factors namely chicken manure rates (0, 2.5, 5, and 7.5 kg per plant) and harvest intervals (2 and 3 months). There was a significant difference in fresh and dry weights of leaves, chlorophyll a and b, carotenoids, nitrogen concentration, anthocyanins, and flavonoids among different manure treatment. The highest concentration and production of bioactive compounds on the bitter leaf was found on the highest treatment of 7.5 kg chicken manure per plant. The harvest interval of three months significantly increased fresh and dry weights of leaves, concentration of anthocyanins, phosphorus, and potassium, uptake of phosphorus and potassium, and production of anthocyanins and flavonoids. Cultivation using chicken manure with frequent period of pruning can enhance the production of biomass as well as secondary metabolites in bitter leaf.

Antibiotic Resistance Pattern of Uropathogens in a Tertiary Care Hospital in Calabar, Nigeria

Introduction: Urinary tract infection is a major reason for hospital visits and a common clinical condition encountered by clinicians. The causative agents of urinary tract infection and their resistant pattern vary globally. The aim of this study was to highlight the profile of pathogens associated with urinary tract infections in our locality. The objective was to investigate the resistant pattern of these microbial isolates from patients with urinary tract infection and offer recommendations for effective treatment. Materials and methods: We retrospectively analyzed the urine culture and antimicrobial sensitivity reports of patients with suspected urinary tract infection at the University of Calabar Teaching Hospital, Calabar, Nigeria, from September 2019 to August 2020. Methicillin resistance was detected by disk diffusion method using 30 µg cefoxitin disk. Production of Extended spectrum beta lactamases was detected by the Combination disk and the double-disk synergy method. Results: Of 979 urine culture and sensitivity reports, 306 (31.26%) were positive for microbial growth. Two microbial isolates each were recovered from urine samples of 5 patients giving a total number of 311 isolates from 306 patients. 45.75% of positive results were in males. The predominant isolate was Escherichia coli (n=97, 31.19%). Extended Spectrum Beta Lactamases (ESBL) producing strains comprised 10.08% (10/238) of Gram-negative group of organisms, while 47.39% (145/306) of all bacterial isolates in our study were multi drug resistant (MDR). 14.29% (6/42) of S. aureus isolates were methicillin resistant S. aureus, while 33.33% (2/6) of methicillin resistant S. aureus (MRSA) were multi drug resistant. Conclusion: Urinary tract infection caused by antimicrobial resistant organisms is common among studied patients. This emphasizes the need for urine culture and sensitivity tests in the management of urinary tract infection.
Policy Transfer Through Return Migration: Lesson From Indonesian Returnees

This article investigates the extent to which policy transfer activities facilitated by Indonesian skilled returnees after finishing their studies in Germany can support various local actors in accelerating developmental progress in their homeland. By using the five-dimensional policy transfer (Evans, 2017), this study found that returnees strengthen the working environment by promoting exchange of knowledge, improving current work methods, and advocating for most common forms of transfer including knowledge sharing, experiences, and networks that they had while abroad. The research also found that most cases of successful policy transfer adoption were characterized by hybridization of new ideas with existing policy and institutional framework in organizations that participated in the program.
LC-MS-MS Analysis and the Antioxidant Activity of Flavonoids from Eggplant Skins Grown in Organic and Conventional Environments

Eggplant fruits are known to contain different classes of phenolic phytochemicals (flavonols, phenolic acids, and anthocyanins) that can exert beneficial effects on human health. This study developed methods for the qualitative and quantitative composition analysis of phenolic compounds in the skin of eggplant fruits harvested following conventional and certified organic farming conditions. Eggplant skin was extracted using aqueous methanol prior to phenolic profiling with UHPLC-ESI-MS-MS. Eggplant skin extracts yielded a profile of 16 phenolic acids, 4 anthocyanins, and 11 flavonols, the first report of quercetin-3-diglucoside, myricetin-3-neohesperidoside, myricetin-3-galactoside, kaempferol-3,7-diglucoside, kaempferol-diglucoside and quercetin-3-rhamnoside. Polyphenolic extracts from all sources potently delayed the cupric ion-mediated lag-time for LDL lipid oxidation and protected Apo-B100 proteins against oxidative modification. Organic growing environment positively influences eggplant skin extract phenolic profile but not antioxidant capacity. In conclusion, eggplant skin has a robust profile of phenolic phytochemicals with excellent antioxidant properties.
Cowpea subjected to organic fertilization and management of the natural vegetation of the savannah of Roraima

Cowpea (Vigna unguiculata (L.) Walp. ) is one of the main sources of nutrients for a large part of the population. To increase your income, there is a need for proper management. This study aimed to evaluate yield components of the cowpea cultivar Aracê subjected to two levels of organic fertilization and three management of the natural vegetation of the savannah of Roraima. The experiment was set up in the experimental area of CCA/UFRR, in Boa Vista, Roraima. The experimental design was a randomized block design in a 3×2 factorial scheme, with four replications. The first factor consisted of the management of the natural vegetation: glyphosate application and cutting or not of the natural vegetation. The second factor consisted of the application or not of cattle manure. Yield components were plant height, number of trifoliate leaves, percentage of normal pods, pod length, number of grains per pod, 100-grain weight, sample grain index, total grain index, and final stand. Organic fertilization with 2 L m-2 of manure increased cowpea production. The management with vegetation cutting in areas with organic fertilization increased the final stand of cowpea plants. The desiccation of natural vegetation with glyphosate was the management that had the highest cowpea production.
Exploring Age and Gender Differences in Narcissism and Perfectionism and Their Mental-Health Correlates

"The changes occurring in modern society can significantly influence individuals’ well-being, mental health and even personality traits such as narcissism and perfectionism. Since studies investigating age and gender differences in narcissism and perfectionism have produced mixed results, and the number of studies conducted in Romanian population is scarce, the main aims of this study were to investigate possible age and gender differences in narcissism, perfectionism and several mental-health indicators in a sample of healthy participants, as well as specific association patterns between these variables within each group of participants. Our sample included 465 millennials and 149 participants over 35 years of age. The results indicate that millennials reported significantly lower levels of narcissism and self-oriented perfectionism than the older generations, higher levels of depressive symptoms and lower levels of autonomy, environmental mastery, purpose in life, and self-acceptance. Female millennials reported lower levels of narcissistic traits and higher levels of socially-prescribed perfectionism, depressive symptoms, personal growth, and positive relations with others than male participants. Older females indicated significantly higher levels of depressive symptoms and loneliness than male participants. Regarding association patterns, in the group of millennial women narcissism was positively correlated with self-oriented, socially-prescribed perfectionism and subjective well-being, and negatively with loneliness, environmental mastery and purpose in life. In millennial males, we found significant positive correlations only between narcissism and subjective well-being and environmental mastery. Our findings may have important implications for the literature regarding millennials and can contribute to the interventions and prevention programs designed to improve their well-being. Keywords: millennials, narcissism, perfectionism, mental health indicators, age and gender differences "
