In vitro assessment of plant growth-promoting potential of rhizosphere actinomycetes from Solanum tuberosum sp. andigena

As part of the rhizosphere microbiota, actinomycetes interact with their host by releasing metabolites that positively influence their host’ growth. The main objective of this study was to evaluate the plant growth-promoting capacity of actinomycetes isolated from the rhizosphere of potato crops collected in the city of San Jeronimo, Andahuaylas, Peru. Forty-nine actinomycetes strains were isolated and screened for their capacity to solubilize phosphates, fix atmospheric nitrogen, produce indole acetic acid (IAA) and produce siderophores. Out of the total number of isolates, 33 (63.27%) solubilized phosphates, 42 (87.72%) fixed atmospheric nitrogen, 10 (20.41%) produced IAA and 18 (24.49%) were siderophore producers; strains AND 13 and AND 16 being the top performers. AND 13 was identified by 16S RNAr gene amplification as Streptomyces sp. The results indicate that actinomycetes can be considered as potential PGPR organisms and could be included in biofertilization programs of potato crops as an alternative to agrochemicals.
Black Dot Disease of Potato

Black dot disease of potato, caused by the fungus Colletotrichum coccodes, is generally considered to be a weak root pathogen of potato. Recent studies in New York and elsewhere have revealed, however, that this disease must be considered as part of the total disease complex affecting potato. Although not as serious a tuberor soilborne pathogen as black scurf (Rhizoctonia so/am) , silver scurf (Helmmthosponum so/ani), or common scab (Streptomyces scabies) , Colletotrichum can cause severe rotting of below-ground plant parts and early plant decline leading to discolored tubers and reduce~ yields. The same black dot organism causes anthracnose or npe-fru1t disease of tomato, and can occur on other solanaceous crops and weed species.
Intelligence and Music: Lower Intelligent Quotient Is Associated With Higher Use of Music for Experiencing Strong Sensations

Intelligence is a key psychological feature associated to emotion and perception. Listening to music is often linked to emotional experience and sensation seeking (SS), traits that have been shown overall negatively correlated with intelligence. In a sample of 53 musicians and 54 non-musicians, we assessed the use of music for experiencing strong emotions through the Music in Mood Regulation (MMR) and the intelligence quotient (IQ) by using the Wechsler Adult Intelligence Scale III (WAIS-III). We found a negative correlation between the full IQ score and the use of music for SS in both musician and non-musician groups. Furthermore, the use of music for SS was negatively correlated with Verbal IQ in musicians, and with Performance IQ in non-musicians. Our findings indicate that less intelligent individuals make a higher use of music for experiencing strong sensations than more intelligent ones. Furthermore, this association is modulated by the individual musical expertise.
Mass Outdoor Events and the Spread of an Airborne Virus: English Football and COVID-19

Mass attendance events are a mainstay of economic and social activity. Such events have public health consequences, facilitating the spreading of disease, with attendant economic consequences. There is uncertainty over the impact such events can have on the spread of disease. We investigate the impact of regular mass outdoor meetings on the spread of a virus by considering football matches in England in February and March 2020 and the spread of Covid-19 into April 2020. There were 340 league and cup football matches with a combined attendance of 1.625m people in March, taking place over 188 of 313 local areas. We look at the occurrence and attendance at matches, and how full the stadia were, and how these variables are related to the spread of Covid-19 in April. We evaluate Covid-19 cases, deaths and excess deaths, all as rates of 100,000 people in an area. We find evidence that mass outdoor events were consistent with more cases and deaths, even after controlling for measurable characteristics of local areas. We find that a football match is consistent with around six additional Covid-19 cases per 100,000 people, two additional Covid-19 deaths per 100,000 people, and three additional excess deaths per 100,000 people. This effect is slightly stronger for the areas of away teams in March, and slightly weaker for matches in February. These results suggest caution in returning to unrestricted spectator attendance at matches. We caveat our analysis though by noting that stadium access and egress routes can be adapted such that some of the opportunities for the spread of an airborne virus could be mitigated. We recommend that the relevant authorities conduct pilot events before determining to what extent fans can return to mass outdoor events.
Youth Experiences of and Views on Un-locked Coercive Placement in Residential Child Care

This article explores Norwegian youth experiences of and views on coercive placement in un-locked residential child care institutions. Inspired by Antonovsky’s salutogenic theory, the article discusses factors that make placement an opportunity for development among youth with serious drug and behavioural problems. The empirical material comes from interviews with 34 youth under and after coercive placement. The findings reveal that coercive placement in un-locked institutions can be helpful and necessary, provided that the institutions have the means available to protect the residents and provide supportive and meaningful treatment content. Factors such as treatment structure, the content of everyday life, clear expectations, and boundaries are discussed as important factors that help the placement to be an opportunity for development among youth with serious drug and behavioural problems.
Enriching Medical Text Classification by Using Machine Learning

Abstract – Health care sector has been noticing some of the most technological advances in the recent years. This has led to the significant improvements in the various aspects of health care such as diagnosis, treatment and also prevention. Technology has been one of the biggest contributors to this rise. This has allowed the patients to achieve effective diagnosis and treatment from the comfort of their homes through the internet platform. There are several websites and web portals for online diagnosis through the internet platform. But most of these approaches have been plagued with inaccuracies as the medical text classification is a highly complicated task. To provide remedy for these issues, the proposed methodology has been detailed in this research article. This article outlines an effective medical text classification technique through the use of NLP techniques such as TF-IDF, noun identification, Bag of Words, etc. The methodology utilizes Logistic Regression and Artificial Neural Networks along with Decision Tree to achieve effective classification of the Medical Text. Extensive Experimentation has been performed to facilitate the extraction of the performance metrics of the system. The outcomes of the experimentation concluded that the proposed methodology significantly outperforms the conventional approaches.
Current transport, magnetic and elemental properties of densified Ag-sheathed Ba1−xKxFe2As2 tapes

Understanding the mechanisms that limit the current transport in granular iron-based superconductors is necessary to unlock their potential for magnet applications. This paper reports the transport critical current surface IC(T,H) of powder-in-tube Ag/Ba1−xKxFe2As2 tapes densified by flat rolling and uniaxial hot pressing. We investigate the amplitude of the isothermal-IC(H)-curve magnetic hysteresis, which is a marker for the electrical connectivity between superconducting grains. This allows us to demonstrate that, in spite of an improved connectivity, the percolative path through weakly linked grains continues to play a role in the IC properties of hot-pressed conductors. The limitations to the current transport due to weak links depend on the orientation of the magnetic field and are more severe when H is on the tape plane. This finding provides a justification to the puzzling evidence that IC(H) can be smaller for magnetic fields applied on the tape plane and not perpendicular to it. Finally, we report an unexpected increase of IC upon augmenting the magnetic field from 0 to ∼2 T. SQUID measurements reveal a superparamagnetic-like magnetic background that takes place in the same range of magnetic fields. A microscopic study of the conductor-core elemental composition provides evidences that these features can be both related to the presence of Fe-rich non-stoichiometric regions in the superconducting core. On a more general note, this study points out that further advances in the in-field current transport properties of powder-in-tube Ag/Ba1−xKxFe2As2 conductors are possible and rely to a large extent on solutions to improve the inter-grain connectivity and the quality of the superconducting phase.
Constitutive Activating and Inactivating Mutants of Eel Luteinizing Hormone Receptor

We analyzed signal transduction of three constitutively activating mutants (M410T, L469R, and D590Y) and two inactivating mutants (D417N and Y558F) of the eel luteinizing hormone receptor (eel LHR), known to occur in human LHR. The objective of this study was to assess the functional effects of these mutations in signal transduction and cell surface loss of receptor. Mutant receptors were transiently expressed in Chinese hamster ovary (CHO-K1) cells. Eel LH-stimulated accumulation of cyclic adenosine monophosphate (cAMP) was measured by homogeneous timeresolved fluorescence (HTRF) assays. The loss of receptors from the cells surface was measured using an enzyme-linked immunosorbent assay (ELISA) in human embryonic kidney (HEK) 293 cells. The cAMP response in cells expressing the wild type eel LHR was increased in a dosedependent manner using eel LH ligand stimulation. Compared with the wild type, cells expressing the activating mutants (M410T, L469R, and D590Y), exhibited a 4.0-, 19.1-, and 7.8-fold increase in basal cAMP response without agonist stimulation, respectively. Their maximal responses to agonist stimulation were approximately 65%, 52%, and 98%, respectively, of those of the wild type. The inactivating mutants (D417N and Y558F) did not completely impair signal transduction, Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 8 September 2020 doi:10.20944/preprints202009.0185. v1 © 2020 by the author(s). Distributed under a Creative Commons CC BY license. 2 and their maximal responses were only 33% and25 % of those of wild type. These data clearly showed that the eel LHR-L469R and D590Y, activating mutants enhanced the rate of the loss of cell surface receptors following treatment with eel LH. Thus, the loss of cell surface receptors in cells expressing mutant eel LHRs was consistent with the eel LH agonist-induced production of cAMP. Our results suggested that the activation of the eel LHR requires appropriate loss of LHRligand complexes from the cell surface.
Formation of homogeneous groups of bovine milk production units via multivariate statistical techniques

EnglishMilk supply chain in Brazil exhibits significant production system heterogeneity in all federal units. Thus, the objective of this study was to form homogeneous groups of bovine milk production units based on the chemical and microbiological quality of the milk via multivariate statistical techniques. A total of 1,541 milk producing units (MPUs), corresponding to 44,089 samples, were analyzed. The first three principal components accounted for 81.38% of the total variation in the data. Principal component 1 (PC1) was associated with the chemical quality of milk (fat, protein [PROT] and total dry extract [TDE] content), while PC2 and PC3 were associated with microbiological quality (somatic cell count [SCC] and total bacterial count [TBC]). The concurrent analysis of the two two-dimensional projections characterized the different productive strata by their quality attributes and identified the positive/negative points of milk microbiological characteristics in each production group. Thus, the dimensionality of the set of 1,541 MPUs was reduced to 15 homogeneous production groups. This method optimizes the use of the dairy industry monthly database and characterizes all the heterogeneities present in dairy production systems. Key words: fat; lactose; protein; total dry extract; typology portuguesA cadeia produtiva brasileira de leite possui expressiva heterogeneidade de sistemas de producao em todas as unidades federativas. Assim, objetivou-se formar grupos homogeneos de unidades de producao de leite bovino atraves de tecnicas estatisticas multivariadas, com base na qualidade quimica e microbiologica do leite. Foram utilizadas 1.541 unidades produtoras de leite (UPL), totalizando 44.089 amostras analisadas. Os tres primeiros componentes principais explicaram 81,38% da variacao total dos dados. O componente principal 1 associou-se a qualidade quimica do leite (gordura, proteina e extrato seco total), enquanto os componentes principais 2 e 3 com a qualidade microbiologica (contagem de celulas somaticas e contagem bacteriana total). Com a analise conjunta das tres projecoes bidimensionais, caracterizaram-se os distintos estratos produtivos quanto aos seus atributos de qualidade e identificaram-se os pontos positivos/negativos das caracteristicas microbiologicas do leite de cada um dos grupos de producao. Assim, obteve-se uma reducao da dimensionalidade do conjunto de 1.541UPL em 15 grupos de producao homogeneos, otimizando a utilizacao da base de informacoes mensais das industrias lacteas, e caracterizando a totalidade das heterogeneidades presentes em sistemas de producao leiteiros.

Gibberellic Acid Application and Plant Spacing Effects on Growth and Yield of Lettuce (Lactuca sativa L.)

Aims: This study aimed to optimize the levels of gibberellic acid (GA3) and plant spacing on growth and yield of lettuce. Study Design: The experiment was laid out in Randomized Complete Block Design with three replications. Place and Duration of Study: Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka-1207, from November 2013 to January 2014. Methodology: The experiment consisted of two factors. Factor A- two levels of gibberellic acid (GA3,) application, viz. G1= 25 ppm and G2= 50 ppm in relation to a control G0 and factor B- four plant spacing viz. S1=15cm x 15cm, S2=20 cm x 20 cm, S3=25 cm x 25 cm and S4=30 cm x 30 cm. GA3 was applied twice as a foliar application by hand sprayer at 20 and 30 days after sowing. First, second and final harvesting was done at 25, 35 and 45 days after sowing respectively. Results: The growth and yield characters of lettuce showed significant variation for different levels of GA3 and plant spacing. Among GA3 levels, 25 ppm GA3 produced the maximum number of leaves (15.6), leaf area (283.9 cm2), fresh weight (91.6 g plant-1), dry weight (11.8 g plant-1), fresh yield (1794 g plot-1) and gross yield (12 t ha-1) at final harvesting compared to control where GA3 was not used. Under plant spacing, highest plant height (17.5 cm), leaf area (281.1 cm2), fresh weight (99.1 g plant-1) and dry weight (12.1 g plant-1) was revealed from wider spacing 30 cm x 30 cm followed by optimum spacing 25cm x 25cm. Meanwhile, closure spacing 15 cm x 15 cm showed maximum fresh yield (1710 g plant-1) and gross yield (15.5 t ha-1) due to higher plant density at final harvesting. Besides, lower chlorophyll content (0.43%) and the highest number of leaves (16.2) was found from 25 cm x 25 cm at final harvesting. So, optimum spacing 25 cm x 25 cm would be more suitable considering different points of view. Moreover, the treatment combinations 25 ppm GA3 with 25 cm x 25 cm exhibited highest benefit-cost ratio (2.04) than other treatments. Conclusions: It is concluded that the combinations 25 ppm GA3 application with 25cm x 25cm spacing would be optimum for better growth and yield of lettuce
Misinformation more likely to use non-specific authority references: Twitter analysis of two COVID-19 myths

This research examines the content, timing, and spread of COVID-19 misinformation and subsequent debunking efforts for two COVID-19 myths. COVID-19 misinformation tweets included more non-specific authority references (e.g., “Taiwanese experts”, “a doctor friend”), while debunking tweets included more specific and verifiable authority references (e.g., the CDC, the World Health Organization, Snopes). Findings illustrate a delayed debunking response to COVID-19 misinformation, as it took seven days for debunking tweets to match the quantity of misinformation tweets. The use of non-specific authority references in tweets was associated with decreased tweet engagement, suggesting the importance of citing specific sources when refuting health misinformation.

New Strategy of Home-Based Exercise during Pandemic COVID-19 in Breast Cancer Patients: A Case Study

The COVID-19 pandemic has posed several challenges for the oncology health care system. The need to improve patients’ Quality of Life (QoL) through exercise, which is related to survival and healing, has increased, especially during lockdowns. Technologies are often used to help with patient care as well as to monitor exercise training. This case study, developed during the pandemic period, aims to evaluate the effectiveness of a proposed home-based combined training (CT) regimen, supervised through online lessons, in increasing QoL and fatigue in breast cancer patients undergoing adjuvant therapy. Additionally, we evaluated the effect of exercise on psychological and functional parameters. Methods: Two breast cancer (BC) survivors were required to participate in 2 h/week of supervised and home-based CT for 16 weeks. Results: Improvements were found in the emotional function of QoL (10% in patient A; 70% in patient B) and in all variables of fatigue (physical fatigue 66% in patient A; 33% in patient B). Conclusion: The findings from this study revealed positive effects of CT on QoL and fatigue perception in BC women undergoing therapy. Both patients attended all training sessions with no adverse events, showing the sustainability of this training as an alternative and affordable method that is capable of improving patients’ wellbeing.
A Broad Continuum of Aeolian Impact Ripple Morphologies on Mars is Enabled by Low Wind Dynamic Pressures

Aeolian ripples are common in sandy environments on Earth and Mars. On Earth, ripples in sorted dune sands typically are <1 cm high and are erased in high winds. On Mars in similar sands, ripple wavelengths commonly exceed 2 m, with much smaller ripples superimposed. Large Martian ripple sizes and juxtaposition of multiple wavelengths have raised questions about origins and the applicability of terrestrial aeolian physics to different planetary environments. Here, two hypotheses are evaluated for large Martian ripples: (1) fluid/wind drag, analogous to ripples formed under water on Earth, as proposed previously for Martian large ripples; and (2) saltation impact splash, the mechanism creating aeolian ripples of much smaller size on Earth. This study evaluates these hypotheses with numerical experiments and Mars rover observations, and concludes that large Martian ripples develop through the saltation impact splash mechanism. The low‐density Martian atmosphere enables aeolian impact ripples to grow much higher into the boundary layer before reaching maximum heights constrained by wind dynamic pressure effects at crests. In this concept, boundary layer conditions influence mature ripple heights more directly than wavelengths. On Mars, low wind dynamic pressures, combined with the impact splash mechanism, also help to explain other distinctively Martian aeolian bedforms, including large longitudinal ripples observed by rovers and orbiters, and transverse aeolian ridges (TARs) distributed widely across the Martian surface. Compared with Earth, low wind dynamic pressures on Mars permit a wider range of ripple sizes, relative ages, morphologies, and orientations in close proximity, as displayed in rover observations.
Pseudoprospective Evaluation of the Foreshock Traffic-Light System in Ridgecrest and Implications for Aftershock Hazard Assessment

The Mw 7.1 Ridgecrest earthquake sequence in California in July 2019 offered an opportunity to evaluate in near-real time the temporal and spatial variations in the average earthquake size distribution (the b-value) and the performance of the newly introduced foreshock traffic-light system. In normally decaying aftershock sequences, in the past studies, the b-value of the aftershocks was found, on average, to be 10%–30% higher than the background b-value. A drop of 10% or more in “aftershock” b-values was postulated to indicate that the region is still highly stressed and that a subsequent larger event is likely. In this Ridgecrest case study, after analyzing the magnitude of completeness of the sequences, we find that the quality of the monitoring network is excellent, which allows us to determine reliable b-values over a large range of magnitudes within hours of the two mainshocks. We then find that in the hours after the first Mw 6.4 Ridgecrest event, the b-value drops by 23% on average, compared to the background value, triggering a red foreshock traffic light. Spatially mapping the changes in b values, we identify an area to the north of the rupture plane as the most likely location of a subsequent event. After the second, magnitude 7.1 mainshock, which did occur in that location as anticipated, the b-value increased by 26% over the background value, triggering a green traffic light. Finally, comparing the 2019 sequence with the Mw 5.8 sequence in 1995, in which no mainshock followed, we find a b-value increase of 29% after the mainshock. Our results suggest that the real-time monitoring of b-values is feasible in California and may add important information for aftershock hazard assessment.
