Published: January 2025

Objective: This study explores the relationship between Chest X-Ray (CXR) imaging and Thoracic CT scans in third-trimester pregnant women, with the Reactive Antibody Rapid Test as an intervening variable, in relation to PCR swab results before delivery.

Theoretical Framework: CXR and Thoracic CT are hypothesized to provide complementary diagnostic information in managing respiratory conditions during pregnancy, with the Reactive Antibody Rapid Test potentially influencing the accuracy of these modalities in predicting PCR outcomes.

Method: A quantitative cross-sectional design with proportional purposive sampling was used. Sixty-two third-trimester pregnant women who underwent CXR, Thoracic CT, and PCR swab tests were included. Data from medical records were analyzed using Importance-Performance Analysis (IPA) to assess the predictive power of CXR and CT imaging in conjunction with antibody test results.

Results and Discussion: The study revealed that the performance of CXR and Thoracic CT imaging (x = 4.07) exceeded expectations (y = 2.73) when correlated with PCR swab results. The Reactive Antibody Rapid Test, however, showed mixed results, particularly when CXR findings were inconclusive. The study discusses the need for better integration of imaging and antibody test results to optimize pre-delivery care.

Research Implications: The findings suggest that while CXR and Thoracic CT are valuable diagnostic tools for managing respiratory conditions in pregnant women, including antibody test results could improve diagnostic accuracy. Hospitals should refine protocols to better integrate these tests.

Originality/Value: This study is one of the first to examine the relationship between CXR, Thoracic CT, and Reactive Antibody Rapid Test results in the context of PCR swab outcomes before delivery in third-trimester pregnant women.

Purpose: Urinary tract infection (UTI) is a common bacterial infection affecting millions worldwide. Escherichia coli (E. coli) is the most prevalent causative agent of UTIs. This study aimed to determine the prevalence, antimicrobial susceptibility profiles and carriage of ESβL resistance genes among uropathogenic E. coli recovered from adults at Mama Lucy Hospital.
Methodology: A cross-sectional study was conducted. A purposive method was used to obtain 347 urine samples from patients who presented with symptoms suggestive of UTI and were cultured for E. coli using cysteine lactose electrolyte-deficient agar and eosin methylene blue agar. The collected urine samples were also subjected to dipstick analysis and microscopy. Questionnaires were used to collect sociodemographic data and possible risk factors for urinary tract infections. The recovered isolates were identified using conventional biochemical tests. Antimicrobial susceptibility profiles were determined using the Kirby diffusion disc method. The occurrence of ESβLs, including TEM, OXA, SHV, and CTX-M, was determined by polymerase chain reaction (PCR).
Findings: The overall prevalence rate of UTIs was 23.7%, whereas the E. coli prevalence rate was 13.3%. The isolates presented high levels of resistance to trimethoprim-sulfamethoxazole (81.3%), amoxicillin-clavulanic acid (66.7%), ciprofloxacin (62.5%), tetracycline (60.4%), ceftriaxone (54.2%), and cefoxitin (54.2%), whereas they were more susceptible to meropenem (14.6%), chloramphenicol (12.5%), and nitrofurantoin (8.3%). A total of 25 of the 46 E. coli isolates were screened for ESβL genes. TEM was the most common gene21/25 (84%), SHV12/25 (48%), OXA 7/25 (28%), and CTX-M 18/25 (66.1%), which indicates a high frequency of β-lactamase gene production among UTIs causing E. coli.
Unique Contribution to Theory, Practice and Policy: Based on these findings, current treatment guidelines should be revised to prevent increasing antimicrobial resistance through continuous surveillance, screening for extended-spectrum beta-lactamase genes, routine culture and antibiotic sensitivity testing. Additionally, the prevalence of UTIs should be continuously monitored to monitor trends that form a basis for preventive and treatment guidelines, such as policy development and prudent use of antibiotics, to reduce the increasing UTI burden in the population.

Wind energy considered to be the most recent source of power that inexpensive, non-depleting, also simple for a variety of users to capture and employ. The location of Ali El Gharbi is one of the preferable sites for clean energy production in Iraq, however as there is a lack of information about the power exploration potentials at this place, more related researches and studies for wind power wind are fundamental. An accurate comprehension for the behaviour of the wind is required for the preparation and operation of every wind conversions to energy project. The study is aimed at investigating the novelty in modifying the Weibull distribution by means of the Fast Fourier Transform with the purpose of estimate the possibility of wind energy harvesting in Ali El-Gharbi area of Ammarah, Iraq. The results from the modification of the Weibull distribution was a reduction in the value of the shape parameter for the new Weibull distribution which will lead to a smoother curve, the reduction of the shape parameter from about 5 to 1 implies a shift from the scenario where failures occur randomly and independently of the parameter.
A second benefit of the modification was a reduction the time for calculation the Weibull parameters and PDF’s with increasing the accuracy. As an outcome of the wind speed data values were recorded at a 10-minutes interval for a year starting from December 2014 till December 2015 at heights of 10, 30, and 50 meters. Subsequently, the datasets were examined by means of the Weibull probability distribution function (WPD) to assess wind energy production, and for the spectral part of the analysis was conducted by employing the Fast-Fourier-Transform. According to the spectral analysis for the data, the average yearly wind speed at 50 m was 6.134 m/sec, whereas highest wind speed recorded there during the day were about 17.011 , and the peak wind speed was 226236.282 m/sec/12hour at a frequency(2 Hz) at that height of 50 m all through night hours. And for lowest values of wind speed was about 115863.7 m/sec/12hour for the (2 Hz) frequency at that height throughout night hours. The blowing of wind was more rapidly in the morning than it was at night periods. While the main wind directions in the region were from the north-northwest and west-northwest.

Abstract. This study attempts to quantify the radiative impact over Réunion Island (21° S, 55° E) in the southern tropical Indian Ocean of the aerosols and water vapor (WV) injected into the stratosphere by the eruption of the Hunga underwater volcano in the South Pacific on 15 January 2022 . Ground-based lidar and satellite passive instruments are used to parameterize a state-of-the-art radiative transfer (RT) model for the first 13 months after the volcano eruption. The descending rate of the aerosol volcanic plume is −8 m d−1. At this rate, aerosols are expected to be present in the stratosphere until the first half of 2025. The overall aerosol and water vapor impact on the Earth's radiation budget for the whole period is negative (cooling, −0.82 ± 0.35 W m−2) and dominated by the aerosol impact (∼ 95 %; the remaining ∼ 5 % is due to the water vapor). At the Earth's surface, aerosols are the main drivers and produce a negative (cooling, −1.04 ± 0.36 W m−2) radiative impact. Water vapor has hardly any radiative effect at the surface. Between the short-term (months 2 to 4 after the eruption, February–April 2022) and mid-term (months 5 to 14 after the eruption, May 2022–February 2023) periods, the aerosol and water vapor radiative effect at the surface and top of atmosphere (TOA) reduces by 22 % and 25 %, respectively. During the mid-term period, heating / cooling (H / C) rate profiles show a clear vertical difference locally in the stratosphere between the aerosol warming impact (18 to 26 km) and the water vapor cooling (22 to 30 km). The resulting aerosol and water vapor heating / cooling rate profile follows an S-shaped curve with peaks slightly larger for the moist layer (−0.09 K d−1) than for the sulfate layer (+0.06 K d−1).

Abstract. We present mass spectroscopic in situ data from rocket flights of two improved ion mass spectrometers in the mesosphere and lower thermosphere region. The instruments were optimized to detect large ions with a mass-to-charge ratio (m/z, mass) of up to m/z 2000 and 20 000 respectively, for analysis of meteor smoke particles. The flights were performed in the framework of the polar mesospheric winter echo (PMWE) campaigns, initiated and coordinated by the Leibniz Institute of Atmospheric Physics (IAP), to investigate polar mesospheric winter radar echoes in Andøya (Norway) in 2018 and 2021. Both flights were successful and allowed the mass number and chemical composition of charged meteor smoke particles to be investigated. We found a complex and diverse composition of positively and negatively charged molecules and particles within our mass range in a region that is notoriously difficult to get mass spectroscopic data from. While at altitudes below 85 km we observed negatively charged particles of up to several thousands of atomic mass units, above this altitude we found possible building blocks of these large particles that form right after their ablation from the parent meteorite material. In the first flight we detected no positively charged particles above m/z 100 and a difficult-to-interpret signal for negatively charged particles beyond our mass range of m/z 2000. In the second flight, however, we detected positively charged particles between around m/z 180 and 350 and a number of different negatively charged particles up to m/z 5500. Due to the very large mass range of m/z 20 000 used in the second flight and the subsequent lower mass resolution, unambiguous mass identification is not possible. A particular interesting pattern was found at 80.8 km of a compound that seems to double its mass around m/z 225, 450, 900 and 1800. Comparing our findings to proposed meteor smoke particle compounds by other authors, our observations would be consistent with magnetite, fayalite and forsterite. However, other possible compounds cannot be excluded.
A CO2–Δ14CO2 inversion setup for estimating European fossil CO2 emissions

Published: January 2025

Abstract. Independent estimation and verification of fossil CO2 emissions on a regional and national scale are crucial for evaluating the fossil CO2 emissions and reductions reported by countries as part of their nationally determined contributions (NDCs). Top-down methods, such as the assimilation of in situ and satellite observations of different tracers (e.g., CO2, CO, Δ14CO2, XCO2), have been increasingly used for this purpose. In this paper, we use the Lund University Modular Inversion Algorithm (LUMIA) to estimate fossil CO2 emissions and natural fluxes by simultaneously inverting in situ synthetic observations of CO2 and Δ14CO2 over Europe. We evaluate the inversion system by conducting a series of observing system simulation experiments (OSSEs). We find that in regions with a dense sampling network, such as western/central Europe, adding Δ14CO2 observations in an experiment where the prior fossil CO2 and biosphere fluxes are set to zero allows LUMIA to recover the time series of both categories. This reduces the prior-to-truth root mean square error (RMSE) from 1.26 to 0.12 TgC d−1 in fossil CO2 and from 0.97 to 0.17 TgC d−1 in biosphere fluxes, reflecting the true total CO2 budget by 91 %. In a second set of experiments using realistic prior fluxes, we find that in addition to retrieving the time series of the optimized fluxes, we are able to recover the true regional fossil CO2 budget in western/central Europe by 95 % and in Germany by 97 %. In all experiments, regions with low sampling coverage, such as southern Europe and the British Isles, show poorly resolved posterior fossil CO2 emissions. Although the posterior biosphere fluxes in these regions follow the seasonal patterns of the true fluxes, a significant bias remains, making it impossible to close the total CO2 budget. We find that the prior uncertainty of fossil CO2 emissions does not significantly impact the posterior estimates, showing similar results in regions with good sampling coverage like western/central Europe and northern Europe. Finally, having a good prior estimate of the terrestrial isotopic disequilibrium is important to avoid introducing additional noise into the posterior fossil CO2 fluxes.
Disentangling spring–neap suspended particulate matter (SPM) dynamics in estuaries

Published: January 2025

Abstract. Suspended particulate matter (SPM) concentrations in estuaries have been observed to vary strongly over the spring–neap cycle through complex interactions between trapping and re-suspension. However, a systematic framework for analysing the processes causing this spring–neap SPM variability in general is missing. In this study we set up such a framework, consisting of three tiers. First, by studying the sediment transport capacity, how the locations of sediment trapping change over the spring–neap cycle is identified. Second, how the transport capacity affects the sediment stock and bottom pool of sediment is studied. This bottom pool only adapts gradually to the changing transport conditions, incorporating a lag or memory effect. Using a two-timescale analysis it is shown that this slow movement of the bottom pool is the leading source of such lag effects. Third, the SPM concentration is explained from an almost instantaneously balanced exchange between the bottom pool and the water column through re-suspension and deposition. We demonstrate the use of this framework on two model cases implemented in the idealised width-averaged iFlow model: an idealised test case where the sediment dynamics do not affect the water motion and a case representative of the Loire estuary, with strong feedback between sediment and the water motion through sediment-induced damping of turbulence. The first is illustrative as it allows a full understanding in terms of cause and effect between water motion, transport, and SPM concentration. In the more realistic Loire case, the SPM dynamics cannot be explained in terms of cause and effect but can explain the trapping locations and timing of maximum concentrations in a systematic way in terms of the governing physical mechanisms.

Published: January 2025

Biology learning is often considered difficult by students, especially on Fungal Kingdom concepts which involves abstract and complex concepts. This causes low student learning motivation. The study aimed to observe the application of a research-based learning model or Research-Based Learning (RBL) with a practicum method to motivate students in learning Fungal Kingdom concepts in class X. This study used a qualitative descriptive approach, with instruments in the form of observation sheets and written tests. The subjects of the study were students in grades X1, X2, and X3 at one of the public high school in Serang in the 2024/2025 Academic Year. Learning takes place following the RBL steps which include problem identification, hypothesis formulation, practicum implementation, discussion, data analysis, and evaluation. The results showed that 74.28% of students achieved scores above the minimum competion criteria with a class average of 82.78. This shows that the application of the RBL model with a practicum method can motivate students in learning Fungal Kingdom concepts. Students become more actively involved, enthusiastic in making observations, and show better understanding
