Rhizobium sp.CCNWYC119: a single strain highly effective as biofertilizer for three different peas (Pigeon pea, Sweet pea and Chick pea)

Rhizobium spp. was isolated from root nodules of Pigeon pea (Cajanus cajan L.), Sweet pea (Lathyrus sativus L.), Chick pea (Cicer arietinum L.). The isolates ware rod shaped, aerobic, gram negative, motile and non-spore forming. Isolates were positive to Catalase, Citrate utilization, Urea hydrolysis, Congored, Nitrification, Oxidase, Triple sugar iron and MacConkey agar test. The isolates can ferment all nine sugars. Then, the isolates identified as Rhizobium spp. depending on above results were subjected to 16S rRNA sequencing for further confirmation and identification. Surprisingly, the isolates were same strain or member of same cluster of Rhizobium and identified as Rhizobium sp.CCNWYC119 strain based on 16S rRNA sequence (98% similarity). Then, different parameters of soil quality enrichment and plant growth viz. plant height; weight of pods and seeds; number, fresh and dry weight of nodules were studied to test the efficacy of the isolate as biofertilizer. Here, inoculant of Rhizobium sp. isolated from Pigeon pea was used as biofertilizer. The results showed the significant increase of nodulation, enrichment of soil of rhizosphere, plant growth and yield for all three types of inoculated peas as compared with non-inoculated control peas indicating that the isolated strain could be used as a common efficient biofertilizer for Pigeon pea, Sweet pea and Chick pea. It was also found that the isolate grew optimally at temperature 28°C and pH 7.0. Moreover, the isolate was sensitive to the higher concentration of NaCl (>1%) and to antibiotics- Mecillinam, Ciprofloxacin, Cotrimoxazole, Pefloxacin, Ceftazidime and Tetracycline.
Nest use and patterns of egg laying and damage by 4 strains of laying hens in an aviary system1.

Laying hens are strongly motivated to use nests for egg laying, and alternative production systems (e.g., aviaries) provide artificial sites to meet this need and ensure efficient collection of clean, undamaged eggs. However, nests are typically not provided to allow simultaneous use by all hens; therefore, competition or mislaid eggs can result. To understand the influence of strain on laying eggs outside nests and damage to eggs, we compared daily patterns of nests use and egg laying among 4 laying hen strains (Hy-Line Brown (HB), Bovans Brown (BB), DeKalb White (DW), and Hy-Line W36 (W36)). Hens were observed over 3 consecutive days in aviaries with colony nests in the enclosure's top tier (2 nests/unit, 4 aviary units/strain, 144 hens/unit). The number and location of hens in nests and the number, location and condition of eggs throughout aviaries were recorded. Most eggs (90 to 95%) were laid in nests; however, brown hens consistently laid more non-nest eggs and damaged more eggs than white hens (P ≤ 0.05). Higher nest occupancy by brown hens was correlated with more non-nest and damaged eggs (P ≤ 0.05). In the morning, brown hens occupied more nest space and laid more nest eggs than white hens (e.g., HB vs. DW: 82.97 and 34.66% of space; 91.35 and 68.73% of nest eggs; P ≤ 0.05). At midday, white hens occupied more nest space and laid more nest eggs than brown hens (e.g., HB vs. DW: 28.47 and 15.81% of space; 27.39 and 8.29% of nest eggs; P ≤ 0.05). Brown hens preferred right nest compartments and laid more eggs there, whereas white hens preferred left compartments and W36 laid more eggs there (P ≤ 0.05). These findings indicate that different strains of hens have different patterns of nest use and laying behavior. In brown hens, heavy morning nest use was related to laying eggs outside nests and more damaged eggs, suggesting insufficient space for oviposition in nests. Specific facility design should be matched to hens' preferences to accommodate behavioral needs of different strains.
Finance and Growth: From the Business Cycle to the Long Run

This paper proposes a new methodology to assess the long-run relationship between economic and financial growth. By linking long-run growth to the properties of business cycles, this methodology offers a better understanding of the channels through which finance can impact long-term growth. We first define the direct elasticity between financial and economic growth to measure the contemporaneous effect of financial growth. If financial booms make recessions more severe, losses of growth during recessions are low when compared with growth supplements during expansions. Beyond this contemporaneous effect of financial booms, we identify a persistent effect of financial growth detrimental to subsequent cycles, which is referred as a hysteresis phenomenon. Then, financial and economic growth rates are positively correlated only up to a certain threshold of financial activity. In our panel of economies, the average level of financial activity is well above this threshold, implying that the total elasticity between finance and growth is negative in the long run.
UV-Pre-Treated and Protein-Adsorbed Titanium Implants Exhibit Enhanced Osteoconductivity

Titanium materials are essential treatment modalities in the medical field and serve as a tissue engineering scaffold and coating material for medical devices. Thus, there is a significant demand to improve the bioactivity of titanium for therapeutic and experimental purposes. We showed that ultraviolet light (UV)-pre-treatment changed the protein-adsorption ability and subsequent osteoconductivity of titanium. Fibronectin (FN) adsorption on UV-treated titanium was 20% and 30% greater after 1-min and 1-h incubation, respectively, than that of control titanium. After 3-h incubation, FN adsorption on UV-treated titanium remained 30% higher than that on the control. Osteoblasts were cultured on titanium disks after 1-h FN adsorption with or without UV-pre-treatment and on titanium disks without FN adsorption. The number of attached osteoblasts during the early stage of culture was 80% greater on UV-treated and FN-adsorbed (UV/FN) titanium than on FN-adsorbed (FN) titanium; osteoblasts attachment on UV/FN titanium was 2.6- and 2.1-fold greater than that on control- and UV-treated titanium, respectively. The alkaline phosphatase activity of osteoblasts on UV/FN titanium was increased 1.8-, 1.8-, and 2.4-fold compared with that on FN-adsorbed, UV-treated, and control titanium, respectively. The UV/FN implants exhibited 25% and 150% greater in vivo biomechanical strength of bone integration than the FN- and control implants, respectively. Bone morphogenetic protein-2 (BMP-2) adsorption on UV-treated titanium was 4.5-fold greater than that on control titanium after 1-min incubation, resulting in a 4-fold increase in osteoblast attachment. Thus, UV-pre-treatment of titanium accelerated its protein adsorptivity and osteoconductivity, providing a novel strategy for enhancing its bioactivity.
Appropriate care for neonates born to mothers with COVID‐19 disease

The global COVID‐19 pandemic has been associated with high rates of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) transmission, morbidity and mortality in the general population. Evidence‐based guidance on caring for babies born to mothers with COVID‐19 is needed. There is currently insufficient evidence to suggest vertical transmission between mothers and their newborn infants. However, transmission can happen after birth from mothers or other carers. Based on the currently available data, prolonged skin‐to‐skin contact and early and exclusive breastfeeding remain the best strategies to reduce the risks of morbidity and mortality for both the mother with COVID‐19 and her baby.
Cohabitation and Marital Stability in the United States

Recent evidence from Canada and Sweden indicates that cohabitation prior to marriage significantly increases the risk of subsequent marital dissolution. In this article we present results testing the hypothesis that cohabitation increases marital disruption in the United States. We find that premarital cohabitation increases the risk of subsequent marital instability. However the effect of cohabitation can be attributed to the fact that cohabitants have spent more time in union than noncohabitants. Once total length of union is accounted for there is no difference in marital disruption between cohabitants and noncohabitants. We argue that subsequent research comparing cohabitants and noncohabitants with respect to marital behaviors that are duration dependent should account for the total amount of time spent in union.We take our data from the fifth follow-up to the National Longitudinal Study of the High School Class of 1972 (NLS) conducted in 1986.

GEOGRAPHIC AND INDIVIDUAL DETERMINANTS OF IMPORTANT AMPHIBIAN PATHOGENS IN HELLBENDERS (CRYPTOBRANCHUS ALLEGANIENSIS) IN TENNESSEE AND ARKANSAS, USA

Abstract: Wildlife diseases are a major threat for species conservation and there is a growing need to implement disease surveillance programs to protect species of concern. Globally, amphibian populations have suffered considerable losses from disease, particularly from chytrid fungi (Batrachochytrium dendrobatidis [Bd] and Batrachochytrium salamandrivorans [Bsal]) and ranavirus. Hellbenders (Cryptobranchus alleganiensis) are large riverine salamanders historically found throughout several watersheds of the eastern and midwestern US. Populations of both subspecies (Ozark hellbender, Cryptobranchus alleganiensis bishopi; eastern hellbender, Cryptobranchus alleganiensis alleganiensis) have experienced precipitous declines over at least the past five decades, and emerging pathogens are hypothesized to play a role. We surveyed Ozark hellbender populations in Arkansas (AR) and eastern hellbender populations in Middle Tennessee (MTN) and East Tennessee (ETN) for both chytrid fungi and ranavirus from swabs and tail tissue, respectively, from 2011 to 2017. Overall, we detected Bd on hellbenders from nine out of 15 rivers, with total prevalence of 26.7% (54/ 202) that varied regionally (AR: 33%, 28/86; MTN: 11%, 4/36; ETN: 28%, 22/80). Ranavirus prevalence (9.0%, 18/200) was comparatively lower than Bd, with less regional variation in prevalence (AR: 6%, 5/ 85; MTN: 11%, 4/36; ETN: 10%, 8/79). We did not detect Bsal in any hellbender populations. We detected a significant negative correlation between body condition score and probability of ranavirus infection (β=–0.13, SE=0.06, 95% confidence interval: –0.24, –0.02). Evaluation of infection load of positive individuals revealed different trends than prevalence alone for both ranavirus and Bd, with MTN having a significantly greater average ranaviral load than both other regions. We documented a variety of lesions that likely have multiple etiologies on hellbenders located within all geographic regions. Our data represent a multiyear pathogen dataset across several regions of C. alleganiensis, and we emphasize the need for continued pathogen surveillance.
Regulatory Mechanisms of Somatostatin Expression

Somatostatin is a peptide hormone, which most commonly is produced by endocrine cells and the central nervous system. In mammals, somatostatin originates from pre-prosomatostatin and is processed to a shorter form, i.e., somatostatin-14, and a longer form, i.e., somatostatin-28. The two peptides repress growth hormone secretion and are involved in the regulation of glucagon and insulin synthesis in the pancreas. In recent years, the processing and secretion of somatostatin have been studied intensively. However, little attention has been paid to the regulatory mechanisms that control its expression. This review provides an up-to-date overview of these mechanisms. In particular, it focuses on the role of enhancers and silencers within the promoter region as well as on the binding of modulatory transcription factors to these elements. Moreover, it addresses extracellular factors, which trigger key signaling pathways, leading to an enhanced somatostatin expression in health and disease.
At-wavelength alignment and testing of the 0.3 NA MET optic

Extreme ultraviolet (EUV) interferometry has been successfully performed for the first time at 0.3 numerical aperture (NA). Extensive EUV “at-wavelength” testing including alignment, was performed on a newly created Micro Exposure Tool (MET) optic designed for sub-50-nm EUV lithographic imaging experiments. The two-mirror, 0.3 NA MET is among the highest resolution light-projection lithography tools ever made. Using both lateral shearing and phase-shifting point-diffraction interferometry, the wavefront was measured across the field of view, and the alignment was optimized in preparation for imaging. The wavefront quality reached 0.55nm RMS (λEUV∕24.5) in a 37-term annular Zernike polynomial series, dominated by higher-order spherical aberration. Measurements included calibrations of the interferometer accuracy, assessment of repeatability, and cross-comparisons of visible and EUV interferometric measurements.
Bioactive Molecular Networking for Mapping the Antimicrobial Constituents of the Baltic Brown Alga Fucus vesiculosus

The brown alga Fucus vesiculosus is common to the intertidal zones of the Baltic Sea, where it is exposed to high fouling pressures by microorganisms. Our previous studies showed, repeatedly, the consistent antimicrobial activity of F. vesiculosus crude extracts against human pathogens, while untargeted metabolomics analyses have revealed a variety of metabolites. In this study, we applied the UPLC-QToF-MS/MS-based “bioactive molecular networking” (BMN) concept on the most bioactive n-hexane and n-butanol subextracts of Baltic F. vesiculosus coupled with in silico dereplication tools to identify the compounds responsible for antimicrobial activity. The first antimicrobial cluster identified by BMN was galactolipids. Our targeted isolation efforts for this class led to the isolation of six monogalactosyldiacylglycerol (MGDG) derivatives (1–6) and one digalactosyldiacylglycerol (DGDG, 7). The MGDGs 5 and 6 and the DGDG 7 exhibited activity against Staphylococcus aureus. The second compound class with high bioactivity was phlorotannins. In particular, phlorethol-type phlorotannins showed high correlations with antimicrobial activity based on the BMN approach, and two phlorotannins (8–9) were isolated. This study shows that antimicrobial components of F. vesiculosus reside in the algal cell walls and membranes and that BMN provides a complementary tool for the targeted isolation of bioactive metabolites.
Guaranteed Success? The Effects of Export Credit Guarantees on Firm Performance

Many countries offer government-backed export credit guarantees to domestic firms. We investigate the effects of such guarantees on firm exports, jobs and value added. Using uniquely detailed and exhaustive transaction-level panel data on guarantees and granular information on trade as well as on exporters and foreign-buyers, we perform difference-in-difference matching estimations. We find that guarantees improve firm performance. However, the effects are strikingly heterogeneous across firm size and response variables. Using guarantees increases the firm-destination probability to export and the value of exports by 18 and 172 percent, respectively, but does not generally increase jobs and value added. Smaller firms benefit the most in terms of exports. Overall, the evidence suggests a causal link from guarantees to firm export performance.
The Cost of Political Connections

Using plant-level data from France, we document a potential cost of political connections for firms that is not offset by other benefits. Politically connected CEOs alter corporate employment decisions to help (regional) politicians in their re-election efforts by having higher job and plant creation rates, and lower rates of destruction in election years, especially in politically contested areas. There is little evidence that connected firms benefit from preferential access to government resources, such as subsidies or tax exemptions. Connected firms are less profitable in the cross-section and also experience a drop in profitability when a connected CEO comes to power.
An intervention designed to investigate habit formation in a novel health behaviour

Abstract Objectives Understanding how to help people form habits is important in improving health interventions. The impact of two behaviour change techniques on behaviour (cues and monitoring) was tested, and the role of psychosocial factors that may predict behaviour change and habit formation were investigated. Methods: Participants (N = 186) were randomised to one of six conditions (behaviour monitoring vs habit monitoring vs irrelevant behaviour monitoring and cued vs not cued) and instructed to engage in a specific, novel behaviour every day for the following 3 weeks. Participants completed measures of behaviour, habit strength, prospective memory, attitude, intention, self-efficacy and motivation at three time points (pre-, post- and one-week follow-up). Results: All participants increased habit strength and behaviour. Post-hoc, it was found that community members, compared to students, developed stronger habits and maintained the behaviour and habit strength at one-week follow-up. Intention, behaviour and habit strength post-intervention moderated behaviour and habit strength maintenance. Conclusion: This research furthers our understanding of how to help people form healthy habits. It was found that any intervention seems to be effective in forming a habit and changing behaviour. Moreover, intention, habit and behaviour were the most important predictors of behaviour change and habit formation maintenance.
Patient Perspectives on Audio-Only Virtual Prenatal Visits Amidst the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Pandemic.

OBJECTIVE To evaluate patient satisfaction after integration of audio-only virtual visits into a pre-existing prenatal care schedule within a large, county-based system during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. METHODS We implemented audio-only prenatal virtual visits in response to the SARS-CoV-2 pandemic within a large, county-based prenatal care system serving predominantly women with low socioeconomic status and limited resources. Using a four-question telephone survey, we surveyed a cross-section of patients who had opted to participate in virtual visits to assess their level of satisfaction surrounding audio-only visits. In addition, average clinic wait times and attendance rates by visit type were examined. RESULTS From March 17 to May 31, 2020, more than 4,000 audio-only virtual prenatal visits were completed in our system. After implementation, the percentage of visits conducted through the virtual platform gradually rose, with nearly 25% of weekly prenatal visits being performed through the virtual platform by the month of May. Clinic wait times trended downward after implementation of virtual visits (P<.001). On average, 88% of virtual prenatal visits were completed as scheduled, whereas only 82% of in-person visits were attended (P<.001). Hospital administration attempted to contact 431 patients who had participated in at least one virtual visit to assess patient satisfaction; 283 patients were reached and agreed to participate (65%). Ninety-nine percent of respondents reported that their needs were met during their audio-only virtual visits. The majority of patients preferred a combination of in-person and virtual visits for prenatal care, and patients reported many benefits with virtual visits. CONCLUSION Audio-only virtual prenatal visits-as a complement to in-person prenatal visits-have specific and distinct advantages compared with video-enabled telehealth in a vulnerable population of women and offer a viable option to increase access to care.
APPLICATION OF A MONOTONOUS FUNCTION TO THE ANALYSIS OF RIDGED WAVEGUIDES

We present a new procedure for determining the resonant frequencies of a rectangular or a circular waveguide filled with a lossless, isotropic, and homogeneous medium. The method is applied to the integral equation. This procedure is based on the use of a monotonous function in the place of the usual determinant to solve non linear eigenvalue problems. The problem is defined on the boundary, applying the BEM. The electric field is expressed using the scalar Green’s function of the rectangular or circular waveguide. Consequently, the discretized problem can be cast into the form of a real matrix eigenvalue problem, whose elements are transcendental functions of the frequency, [A][X]=0. This system can be solved by finding the eigenvalues as zeros (or minimum) of the determinant of [A]. In this paper, we use a systematic procedure to determine modes in waveguides. The efficiency of this approach consists in vanishing of a function which results from the building of a particular quadratic form of the operator appearing in the formulation of the problem rather than vanishing the determinant itself. This built function has the intrinsic property to be monotonous and to have the same zeros as the determinant. Accordingly, it is possible to save computing time and to avoid that some zeros been missed. Very agreements have been found when the solutions obtained for TM modes are compared with the ones obtained by the classical methods.
Effective Representation of River Geometry in Hydraulic Flood Forecast Models

Bathymetric data are a critical input to hydraulic models. However, river depth and shape cannot be systematically observed remotely, and field data are both scarce and expensive to collect. In flood modeling, river roughness and geometry compensate for each other, with different parameter sets often being able to map model predictions equally well to the observed data, commonly known as equifinality. This study presents a numerical experiment to investigate an effective yet parsimonious representation of channel geometry that can be used for operational flood forecasting. The LISFLOOD‐FP hydraulic model was used to simulate a hypothetical flood event in the Clarence catchment (Australia). A high‐resolution model simulation based on accurate bathymetric field data was used to benchmark coarser model simulations based on simplified river geometries. These simplified river geometries were derived from a combination of globally available empirical formulations, remote sensing data, and a limited number of measurements. Model predictive discrepancy between simulations with field data and simplified geometries allowed an assessment of the geometry impact on inundation dynamics. In this study site, the channel geometrical representation for a reliable inundation forecast could be achieved using remote sensing‐derived river width values combined with a few measurements of river depth sampled at strategic locations. Furthermore, this study showed that spatially distributed remote sensing‐derived inundation levels at the very early stages of a flood event have the potential to support the effective diagnosis of errors in model implementations.
