Prevalence and correlates of teenage pregnancy among in-school teenagers during the COVID-19 pandemic in Hoima district western Uganda–A cross sectional community-based study

Background The COVID-19 pandemic related restrictions and lockdown measures had compromised the routine delivery and access of sexual and reproductive health and rights services to the population including the teenage girls. However, the teenage pregnancy rates during COVID-19 pandemic period were poorly documented. This study aimed at determining the prevalence and the factors associated with teenage pregnancy among in-school teenage girls during the COVID-19 pandemic period in Hoima District Uganda. Methods This was a descriptive cross-sectional study that employed quantitative research methods. A total of 314 in-school teenage girls aged 13–19 years were selected using a multi-stage sampling techniques. Interviewer-administered questionnaires were used to collect the data from the participant’s homes during the period December 2021-January 2022. Data analysis was done using univariate, bi-variate, and multivariate. Results The prevalence of teenage pregnancy among the in-school teenage girls in Hoima district Uganda was 30.6% [96/314]. Higher teenage pregnancy rates were prevalent among the unmarried teenage girls [aOR: 9.6; 95%CI: 4.64–19.87; p = 0.000], teenage girls studying from boarding schools [aOR 2.83, 95%CI 1.36–5.86, p = 0.005], contraceptive non-users [aOR: 2.54; 95%CI: 1.12–5.4; p = 0.015] and teenage girls involved in sex trade [aOR 3.16, 95%CI 1.5–6.7, p = 0.003]. The factors associated with the reduced likelihood for teenage pregnancy included being an adult teenage girl aged 18–19 years [aOR: 0.15; 95%CI: 0.07–0.32; p = 0.000] and not receiving sex education during the period [aOR 0.36, 95%CI 0.13–0.62, p = 0.024]. Conclusion The results indicated that 3 out of 10 in-school teenage girls from Hoima district Uganda got pregnant during the COVID-19 pandemic period of 2021. Teenage pregnancy was prevalent among teenage girls who don’t use modern contraceptive methods and those involved in sex trade. Teenage pregnancy was however, less prevalent among adult teenage girls aged 18–19 years. The findings point to the need for health stakeholders to innovate creative policies, contingency plans and programmes aimed at delaying age for sexual activities, increasing contraceptive use and minimizing pregnancy risk from sex trade among in-school teenage girls during COVID-19 pandemics.
Beyond money: Risk preferences across both economic and non-economic contexts predict financial decisions

Important decisions about risk occur in wide-ranging contexts, from investing to healthcare. While an underlying, domain-general risk attitude has been identified across contexts, it remains unclear what role it plays in shaping behavior relative to more domain-specific risk attitudes. Clarifying the relationship between domain-general and domain-specific risk attitudes would inform decision-making theories and the construction of decision aids. The present research assessed the relative contribution of domain-general and domain-specific risk attitudes to financial risk taking. We examined risk attitudes across different decision domains, as revealed through a well-validated measure, the Domain-Specific Risk-Taking Scale (DOSPERT). Confirmatory factor analysis indicated that a domain-general risk attitude shaped responses across multiple domains, and structural equation modeling showed that this domain-general risk attitude predicted observed behavioral risk premiums in a financial decision-making task better than domain-specific financial risk attitudes. Thus, assessments of risk attitudes that include both economic and non-economic domains improve predictions of financial risk taking due to the enhanced insight they provide into underlying, domain-general risk preferences.
Can a knee sleeve influence ground reaction forces and knee joint power during a step-down hop in participants following anterior cruciate ligament reconstruction? A secondary analysis

Purpose Elastic knee sleeves are often worn following anterior cruciate ligament (ACL) reconstruction. The study aimed to define immediate and 6-week effects of wearing a knee sleeve on ground reaction forces (GRF) and knee joint power during a step-down hop task. Methods Using a cross-over design, we estimated GRF and knee kinematics and kinetics during a step-down hop for 30 participants following ACL reconstruction (median 16 months post-surgery) with and without wearing a knee sleeve. In a subsequent randomised clinical trial, participants in the ‘Sleeve Group’ (n = 9) wore the sleeve for 6 weeks at least 1 hour daily, while a ‘Control Group’ (n = 9) did not wear the sleeve. We compared the following outcomes using statistical parametric mapping (SPM): (1) GRF and knee joint power trajectories between three conditions at baseline (uninjured side, unsleeved injured and sleeved injured side); (2) GRF and knee joint power trajectories within-participant changes from baseline to follow-up between groups. We also compared discrete peak GRFs and power, rate of (vertical) force development, and mean knee joint power in the first 5% of stance phase. Results SPM showed no differences for GRF for the (unsleeved) injured compared to the uninjured sides; when wearing the sleeve, injured side mean power in the first 5% of stance increased significantly from a concentric to an eccentric power. Discrete variables showed lower peak anterior (propulsive) GRF, mean power in the first 5% of stance, peak eccentric and concentric power for the injured compared to the uninjured sides. After six weeks, a directional change for vertical GRF differed showed slightly decreased forces for the Control Group and increased forces for the Sleeve Group. Conclusion Wearing a knee sleeve on the anterior cruciate ligament injured knee improved knee power during the first 5% of stance during the step-down hop. No consistent changes were observed for ground reaction forces for SPM and discrete variable analyses. Wearing the knee sleeve at least one hour daily for 6-weeks lead to a directional change of increased vertical GRF for the Sleeve Group at follow-up.

Interventions and outcomes of COVID-19 patients in a community hospital–A single center study comparing the first and second waves

Background We have had 3 coronavirus-related pandemics in the last two decades. Each has brought significant toll and with each case there was no cure. Even as vaccines have been developed for the current strain of the virus thereby increasing the prospects of bringing transmissions in communities to a minimum, lessons from this pandemic should be explored in preparation for future pandemics. Other studies have looked at differences in characteristics of patients and mortality rates between the first two waves. In our study we not only identify the differences in outcomes but also explore differences in hospital specific interventions that were implemented at Jersey City Medical Center, NJ, a community-based hospital. Aim The aim of this study is to assess the differences between the first two waves of the COVID -19 pandemic in terms of management and outcomes to help identify any key lessons in the handling of future pandemics. We compared the population demographics, interventions and outcomes used during the first two waves of COVID-19 in a community-based hospital. Methods This is a retrospective single-center cross-sectional study including Laboratory confirmed COVID-19 patients requiring oxygen supplementation admitted at Jersey City Medical Center during the first wave (April 1 to June 30, 2020) and the second wave between (October 1, 2020, and January 1, 2021). The Chi-squared test was used to assess the relationship between categorical variables and the T- test for continuous variables. A Logistic regression model was built comparing the second to the first wave while accounting for important covariates. Results There was a combined total of 473 patients from both waves. Patients in the first wave were older (66.17 years vs 60.38 years, p <0.01), had more comorbidities (2.75 vs 2.29, p 0.003), had more severe disease (50% vs 38.78% p of 0.002), had a longer length of stay (14.18 days vs 8.77 days, p <0.001) and were more likely to be intubated (32.49% vs 21.9 4%, p 0.01). In the univariate model, the odds of mortality in the second wave compared to the first wave was 0.63 (CI, 0.41–0.96) and 1.73 (CI, 0.65–4.66) in the fully adjusted model. Conclusion Overall, there was no statistically significant difference in mortality between the two waves. Interventions that were noted to be significantly different between the two waves were, increased likelihood of mechanical intubation in the first wave and increased use of steroids in the second wave compared to the first.
Habitat suitability and connectivity modeling predict genetic population structure and priority control areas for invasive nutria (Myocastor coypus) in a temperate river basin

The nutria (Myocastor coypus), also known as the coypu, is a semi-aquatic, invasive rodent native to South America that causes damage to natural riverine and wetland habitats in many parts of the world, including South Korea. Understanding habitat use, connectivity, and gene flow of nutria populations is critical for the sound management of local and regional ecosystems. Here, we assessed habitat suitability and connectivity in relation to the genetic structure of nutria populations in the Nakdong River Basin of South Korea. A total of 321 nutria occurrence sites and seven environmental variables were used to perform ensemble habitat suitability modeling using five species distribution models (SDMs), including boosted regression trees, maximum entropy model, random forest, generalized linear model, and multivariate adaptive regression splines. Using graph and circuit theory approaches, we assessed the population gene flow and current flow betweenness centrality (CFBC) of suitable habitats derived from the ensemble SDM. All SDMs performed well with a range of test AUC values from 0.962 to 0.970 (mean = 0.966) with true skill statistic values over 0.8. The minimum temperature of the coldest month, mean temperature of the warmest quarter, precipitation of the driest quarter, and distance from water bodies were important predictors in nutria habitat modeling. Nutria population gene flow was significantly correlated with the least-cost path distance on a cost resistance surface based on ensemble habitat suitability modeling and roads (Mantel’s r = 0.60, p < 0.05). Finally, the CFBC positively correlated with the genetic diversity of nutria populations was used to identify priority control areas. Habitat suitability and connectivity modeling not only revealed environmental conditions and areas that support the survival and spread of nutrias, but also improved our understanding of the animals’ genetic population structure, thereby indicating priority areas to target for eradication.
On the skewness of the temperature derivative in turbulent flows

This note provides some explanation of the fact that, contrary to the requirements of local isotropy, the skewness S of the streamwise temperature derivative ∂θ/∂x1 has been observed to be a non-zero constant of magnitude of about unity in high-Reynolds-number and high-Péclet-number turbulent shear flows. Measurements in slightly heated homogeneous shear flows and in unsheared grid turbulence suggest that S is non-zero only when the mean shear dU1/dx2 and the mean temperature gradient dT/dx2 are both non-zero. The sign of S is given by –sgn (dU1/dx2). sgn (dT/dx2). For fixed dU1/dx2, S is of the form tanh (αdT/dx2), α being a constant, while for fixed dT/dx2, it is of the form S/S* = 1 − β1 exp (− β2τ), where S* is a characteristic value of S, β1 and β2 are positive constants, and τ can be interpreted as a ‘total strain’. The derivative skewness data in other (inhomogeneous) shear flows are also compatible with the latter relation. Predictions from a simplified transport equation for $\overline{(\partial\theta/\partial x_1)^3}$, derived in the light of the present experimental observations, are in reasonable agreement with the measured values of S. A possible physical mechanism maintaining S is discussed.
Flood Risk, Uncertainty, and Scientific Information for Decision Making: Lessons from an Interdisciplinary Project

The magnitude of flood damage in the United States, combined with the uncertainty in current estimates of flood risk, suggest that society could benefit from improved scientific information about flood risk. To help address this perceived need, a group of researchers initiated an interdisciplinary study of climate variability, scientific uncertainty, and hydrometeorological information for flood-risk decision making, focused on Colorado's Rocky Mountain Front Range urban corridor. We began by investigating scientific research directions that were likely to benefit flood-risk estimation and management, through consultation with climatologists, hydrologists, engineers, and planners. In doing so, we identified several challenges involved in generating new scientific information to aid flood management in the presence of significant scientific and societal uncertainty. This essay presents lessons learned from this study, along with our observations on the complex interactions among scientific information, unc.
The equilibria and evolutions of magnetized, rotating, isothermal clouds. III - Critical mass

The equilibrium solutions of magnetized rotating clouds in a static external medium have been obtained. From these solutions, it is shown that there is a critical mass which can be supported by a given magnetic flux and specific angular momentum. For the same magnetic flux, mass, and total angular momentum, two different solutions are obtained with different central densities. The comparison of clouds with fixed magnetic field strength shows that faster rotating clouds have a flatter structure. A technique is presented for using the magnetic flux and specific angular momentum to determine the maximum mass of the rotating magnetized cloud. 25 refs.
Weighted polynomial approximation, quasianalyticity and analytic continuation.

The difficulties can be quite varied depending on the choice of the set X, the space B and the family ,̂ and over the years this question has given rise to a very rieh body of knowledge. In the present article we shall be concerned with two variants of the general approximation problem whose origins can, in retrospect, be traced back to the seminal ideas of Weierstrass and Runge. Of particular interest here are situations that occur when X is either the entire real line P or a bounded simply connected domain Ω and & is the set of all complex analytic polynomials. In each of these settings we have the framework for a problem that has been widely studied and which is closely related to a number of important questions in various parts of analysis. Our main objective is to extend certain well-known theorems from the line to the planar context and in so doing we shall draw heavily from three areas. They are:
Multi-frequency study of the B3-VLA sample. III. Polarisation properties

This paper is the third of a series, and presents the results of the linear polarisation of the B3-VLA sample, at 1.4, 2.7, 4.8 and 10.5 GHz. We find that flat-spectrum sources are significantly less polarised than the steep ones at 10.5 GHz. A trend is seen for sources with larger linear size to be more strongly polarised. Compact steep-spectrum sources (CSSs) exhibit much stronger depolarisation than non-CSSs. Flat-spectrum sources are characterized by almost constant, and low, degrees of polarisation over the whole wavelength range studied here. We add 143 new Rotation Measures to the available database published by Wielebinski & Krause (1993). An important result is that the decrease of the degree of polarisation is almost linear with wavelength and does not drop to zero at lower frequencies. This behaviour cannot be fitted by any existing model of external depolarisation or intrinsic Faraday dispersion. We consider an intrinsic process producing the observed depolarisation, involving three source components with different emissivities and Faraday depths, while the Faraday rotation must arise from a foreground screen, most likely Galactic in origin.
Heterogeneous distribution of interstitial oxygen in annealed Czochralski‐grown silicon crystals

It is shown that interstitial oxygen infrared (IR) absorption at 515 cm−1 decreases anomalously compared with the absorption at 1106 cm−1 in heat‐treated Czochralski‐grown silicon wafers. This phenomenon is described by the close correlation between the absorption coefficient ratio αr (α1106/α515), the half‐bandwidth of the 1106‐cm−1 peak, and the precipitated oxygen content during heat treatments. As a result, it is suggested that on the basis of IR absorption spectrum data interstitital oxygen atoms distribute heterogeneously in a silicon matrix as the forestage of Si‐0 complex precipitation.
Size dependent magnetic and dielectric properties of nano CoFe2O4 prepared by a salt assisted gel-combustion method

In this communication, we report the preparation and properties of nano-CoFe2O4 by gel combustion in presence of KCl and subsequent heat treatments. The products were characterized by X-ray diffraction, Infrared spectroscopy, and Mossbauer Spectroscopy. Spinel type structure with all Fe in 3+ oxidation states was confirmed from the XRD and Mossbauer spectroscopy. The average crystallite sizes of the studied samples were about 6 and 50 nm. Low temperature magnetic and dielectric properties of the samples were studied by superconducting quantum interference device magnetometry and ac-impedance spectroscopy. The field and temperature dependent magnetization studies indicated superparamagnetic nature for 6 nm sample and ferromagnetic nature for 50 nm sample. The temperature-dependent dielectric properties measured over a wide range of frequencies indicated an increasing trend of dielectric permittivity with the decrease in crystallite size. Variable range polaron hopping conduction was observed in both samples.
Non-Darcian Effects on the Mixed Convection Heat Transfer in a Metallic Porous Block with a Confined Slot Jet

The present numerical investigation addresses non-Darcian effects on the mixed convection heat transfer in a metallic porous block with a confined slot jet. The generalized model of the momentum equation, which is also known as the Forchheimer-Brinkman extended Darcy model, was used in representing the fluid motion inside the porous layer. The local thermal equilibrium condition was assumed to be valid for the range of the thermophysical parameters considered in the present investigation. The transport equations were solved using the finite element formulation based on the Galerkin method of weighted residuals. The validity of the numerical code used was ascertained by comparing our results with previously published results. Our results revealed that the heat transfer performance of the slot jet was 2.4 times as large as that without the presence of a porous block. In addition, the average Nusselt number was found to increase with a decrease in porosity and an increase in the thermal conductivity ratio. The present results illustrate that the average Nusselt number increases with a decrease in the dimensionless height of the porous layer up to H porous = 0.05 , after which the Nusselt number decreases.
On a Generalized Finite Intersection Property

We continue the study of the right finite intersection property under a weaker condition on annihilators, introducing the concept of generalized right finite intersection property (simply, generalized right FIP). We observe the structure of rings with the generalized right FIP and examine the generalized right FIP for various kinds of basic extensions of rings with the property. We show that the generalized right FIP does not go up to polynomial rings, and that the 2-by-2 full matrix ring over a domain has the generalized right FIP. In the process, we also obtain an equivalent condition for which a nonzero polynomial, over the ring of integers modulo n ≥ 2, is a non-zero-divisor.
Lunaemycins, New Cyclic Hexapeptide Antibiotics from the Cave Moonmilk-Dweller Streptomyces lunaelactis MM109T

Streptomyces lunaelactis strains have been isolated from moonmilk deposits which are calcium carbonate speleothems used for centuries in traditional medicine for their antimicrobial properties. Genome mining revealed that these strains are a remarkable example of a Streptomyces species with huge heterogeneity regarding their content in biosynthetic gene clusters (BGCs) for specialized metabolite production. BGC 28a is one of the cryptic BGCs that is only carried by a subgroup of S. lunaelactis strains for which in silico analysis predicted the production of nonribo-somal peptide antibiotics containing the non-proteogenic amino acid piperazic acid (Piz). Comparative metabolomics of culture extracts of S. lunaelactis strains either or not holding BGC 28a combined with MS/MS-guided peptidogenomics and 1H/13C NMR allowed to identify the cyclic hexapeptide with the amino acid sequence (D-Phe)-(L-HO-Ile)-(D-Piz)-(L-Piz)-(D-Piz)-(L-Piz), called lunaemycin A, as the main compound synthesized by BGC 28a. Molecular networking further identified 18 additional lunaemycins, 14 of them having their structure elucidated by HRMS/MS. Antimicrobial assays demonstrated a huge bactericidal activity of lunaemycins against Gram-positive bacteria including multi-drug resistant clinical isolates. Our work demonstrates how accurate in silico analysis of a cryptic BGC can highly facilitate the identification, the structural elucidation, and the bioactivity of its associated specialized metabolites.
Refractivities of and at wavelengths of 632.99 and 1300 nm

The refractivities of sulphur hexafluoride and thionyl fluoride have been measured at wavelengths of 632.99 and 1300 nm using a polarization interferometer. The value obtained for at 632.99 nm is in close agreement with results of previous workers, which gives credence to the new values for at 1300 nm and for at both wavelengths. is produced in electrical discharges through as a consequence of dissociation and these refractivity data may find an application in the interferometric monitoring of gas degradation in discharges.
Boundary conditions for open quantum systems driven far from equilibrium

This is a study of simple kinetic models of open systems, in the sense of systems that can exchange conserved particles with their environment. The system is assumed to be one dimensional and situated between two particle reservoirs. Such a system is readily driven far from equilibrium if the chemical potentials of the reservoirs differ appreciably. The openness of the system modifies the spatial boundary conditions on the single-particle Liouville\char22{}von Neumann equation, leading to a non-Hermitian Liouville operator. If the open-system boundary conditions are time reversible, exponentially growing (unphysical) solutions are introduced into the time dependence of the density matrix. This problem is avoided by applying time-irreversible boundary conditions to the Wigner distribution function. These boundary conditions model the external environment as ideal particle reservoirs with properties analogous to those of a blackbody. This time-irreversible model may be numerically evaluated in a discrete approximation and has been applied to the study of a resonant-tunneling semiconductor diode. The physical and mathematical properties of the irreversible kinetic model, in both its discrete and its continuum formulations, are examined in detail. The model demonstrates the distinction in kinetic theory between commutator superoperators, which may become non-Hermitian to describe irreversible behavior, and anticommutator superoperators, which remain Hermitian and are used to evaluate physical observables.
