Association between Delivery during Off-Hours and the Risk of Severe Maternal Morbidity: A Nationwide Population-Based Cohort Study

This study evaluated the association between off-hour deliveries and the risk of severe maternal morbidity (SMM). Data regarding Korean deliveries between 2005 and 2019 obtained from the National Health Insurance Service were used. SMM was evaluated using an algorithm developed by the United States Centers for Disease Control and Prevention. Modified Poisson regression analyses were conducted to investigate the association between off-hour deliveries and SMM, with stratification by hospital region and the number of beds. Approximately 32.7% of the 3,076,448 nulliparous women in this study delivered during off-hours, including 2.6% who experienced SMM. Patients who delivered at night had the highest risk of SMM (weekday nights, adjusted risk ratio (aRR): 1.41, 95% confidence interval (CI): 1.38–1.44; weekend nights, OR: 1.40, 95% CI: 1.34–1.46). The SMM of night deliveries was higher at hospitals located in small cities and those with 100–499 beds (weekend night: small cities, aRR: 1.49, 95% CI: 1.40–1.59; 100–499 beds, aRR: 1.83, 95% CI: 1.67–2.01; weekday night: small cities, aRR: 1.46, 95% CI: 1.42–1.51; 100–499 beds, aRR: 1.70, 95% CI: 1.62–1.79). Therefore, nighttime deliveries are associated with a higher risk of SMM, especially at hospitals located in small cities and those with 100–499 beds.
Impact of Different Surface Treatments on Bond Strength of CAD/CAM Fabricated Y-TZP Ceramic Onlays Subjected to Thermo-mechanical Cyclic Loading

Objectives: The aim of this study intended to evaluate the effect of various surface treatments on the adhesion of CAD/CAM fabricated Y-TZP ceramic onlays. Materials and methods: Forty-eight, cracks-free extracted human molars have been acquired in the study. The specimens have been divided randomly according to surface treatment of Zirconia into four main groups of twelve specimens each as follows (n=12): group1: tribochemical silica coating; group 2: sandblasting; group 3: sandblasting with primer; and group 4: sandblasting and laser with primer. The first half of the specimens were put through the tests right away, whereas the other half were put through the tests after being subjected to thermo-mechanical cyclic stress. Buehler Isomet 4000 Cutting Machine (IsoMetTM 4000, Buehler Ltd, Lake bluff, LL, USA) was used for the preparation of standardized onlays cavities. Then micro-tensile bond strength test μTBS was performed. Data were statistically analyzed using the Shapiro-Wilk, post hoc-Tukey, student t-test, and one-way ANOVA tests. Results: The outcome of the study revealed statically significant differences in μTBS between all groups. The most favorable bonding was in the group of sandblasting with primer (12.50 ± 2.40) and the least was with the tribochemical silicoating (3.70 ± 0.96) (P=0.002). Conclusions: Within the parameters of this study, the different surface treatments had a significant difference in μTBS. Sandblasting with primer consider the most favorable outcome of the current study. However, thermomechanical cyclic loading deteriorates the bond strength when using sandblasting alone.
Chemical, physical, and optical characterization of aerosols during PAUR II experiment

[1] During a 1-month campaign conducted in May 1999 in the frame of Photochemical Activity and Solar Ultraviolet Radiation (PAUR II) project, determination of the ionic composition and physical and optical properties of the aerosol have been performed at a coastal site in Crete. Non-sea-salt sulfate (nss-SO42−), nitrate (NO3−) non-sea-salt calcium (nss-Ca2+), and ammonium (NH4+) have been identified as the main non-sea-salt ionic components of the aerosol. Air mass origin was found to be an important factor controlling the variation of the above ions as well as their particle size distribution. During the experiment, aerosol scattering coefficient ranges from 2 to 51 (M m−1) with no significant difference between dusty and nondusty periods. Significant correlations have been observed between (NH4)2SO4 mass measured during the campaign, aerosol scattering coefficient, and aerosol single-scattering albedo indicating the key role of (NH4)2SO4 in determining the radiative forcing of the eastern Mediterranean area. Finally, non-sea-salt calcium was found to better reproduce the variation of optical depth, more than any other ionic species.
EVOLUTION OF ENRICHMENT OF SEDIMENTS BY TRACE METALS (Ni AND Zn) IN A DAM OF URBANIZED WATERSHED

Sediments represent and provide a response to the condition of the environmental system in which they are found, acting as a point for deposition of contaminants. Upon developing studies of sediment columns, it is possible to obtain the historic records of substances arising from activities developed in the watershed over recent years. In this context, the present study investigates the enrichment of the sediments produced in an urban residential catchment area by the trace metals zinc and nickel. The sediment fraction smaller than 63 μm was analyzed in three sediment cores from the dam. Chemical analyses verified the concentration of trace metals by the acid digestion method EPA 3050. In carrying out analyses of the evolution of urban settlement in the watershed, the values corresponding to natural and human-impacted areas were determined through the use of different remote sensing products: aerial photographs (from 1972 and 1991) and high resolution satellite images (from 2003 and 2008). Natural areas were reduced in four decades, and population density in already human-impacted areas proved to be an important factor for understanding the urbanization process of the area. All sediment samples analyzed showed Zn and Ni concentrations above the local background value and with a pattern of growth.
A comparison of psychological traits in elite, sub-elite and non-elite English cricketers

Within contemporary sport there is a need to highlight those psychological traits that distinguish performers at the height of their sport from the subsequent levels. The present study investigates psychological traits of elite, sub-elite and non-elite English cricketers in order to establish whether traits differ amongst the three levels of performer. A sample of 60 male cricketers (Mean age = 22.72 years, SD = .75), deriving from County Cricket Clubs (Elite cricketers), MCC Universities (Sub-elite cricketers) and National Cricket Clubs (Non-elite cricketers) were examined in the pre-season of 2011. Three questionnaires were administered, assessing mental toughness (SMTQ; Sheard, Golby & van Wersch, 2009), coping strategies (WOCS; Madden, Summers & Brown, 1988, as cited in Madden, Kirkby & McDonald, 1989) and motivation (SMS-6; Mallett, Kawabata, Newcombe, Otero-Forero & Jackson, 2006). In line with past research, it was hypothesised that the three levels of performer would differ significantly on such measures. Predictions regarding specific relations were made a priori. Multiple one way ANOVA’s revealed that performers only differed significantly (F = 2, 57, p < 0.003) on measures of constancy (SMTQ), although a trend for external regulation (SMS-6) was noticeable. In regards to the former, non-elite cricketers were found to score significantly lower than elite and sub-elite cricketers, suggesting that non-elite cricketers are less determined to achieve success than elite and sub-elite players. In reference to external regulation, sub-elite cricketers scored higher than elite and non-elite players, implying that sub-elite cricketers may be more likely than elite and non-elite players to participate in order to obtain rewards. The results suggest that cricket performers may not significantly differ in the psychological traits they possess, with the only exception being constancy.
Population variation within the Iron Age of southern Africa: an assessment using dental anthropological and cranio-mandibular metric techniques

Evidence for iron smelting, agriculture, elaborate pottery styles and increased sedentism appears abruptly in areas previously inhabited by hunter-gatherers and herders during the Early Iron Age (EIA) of southern Africa from around 250CE. Ceramic evidence connects these (cultural) populations to the second millennium Iron Age sites in eastern Botswana. This material culture differs from second millennium Late Iron Age (LIA) sites in South Africa which are attributed to migrations from east Africa and are connected, via the material culture, to modern Sotho-Tswana and Nguni speakers. Although the material culture of this period is well-studied, there is a gap in correlating Iron Age biological identity with the established cultural identity. Here I present an analysis of metric and nonmetric dental and cranial variation to better understand biological relationships among these samples. Specimens from the LIA, EIA and Eastern Botswana are compared with each other, and to specimens from Iron Age Zambian sites, modern Bantu-speakers and a historic Ndebele site from the midnineteenth century. This research indicates few differences between the EIA and LIA groups, although surprisingly a sample from eastern Botswana is more similar to the LIA group than the EIA group. The Iron Age samples are significantly different from the modern sample, while the historic sample lies intermediate to the Iron Age and modern samples, indicating that Iron Age peoples had a pattern of dental and cranio-mandibular variation that differs from what is seen in modern (admixed? ) descendants. This research has important implications for our understanding of the sub-Saharan African dental complex, showing population differences within this complex (between Khoesan and Iron Age peoples) as well as variation over time (between Iron Age peoples and modern Bantuspeakers). This indicates that, while farmers within the Iron Age of southernmost Africa are generally homogenous, there are important differences between populations in sub-Saharan Africa that reflect complex and differing histories.

Internal Loading of an Inhomogeneous Compressible Earth With Phase Boundaries

SUMMARY We use an approach described by Dehant & Wahr (1991) to estimate the geoid and boundary topography caused by mass loads inside the Earth. We show how the estimates are affected by compressibility and a radially varying density distribution, and by the presence of phase boundaries with density discontinuities. We compare results for earth models that have a chemical boundary at 670 km depth with those that have a phase boundary at that depth. We find that the 670 km topographies predicted for models with a chemical boundary are several times larger than for models with a phase boundary, depending principally on the value of the Clapeyron slope in the phase case. The geoid predicted in the chemical boundary case is about 30-40 per cent smaller than that predicted in the phase case. The effects of compressibility and radially varying density are likely to be small. We estimate the laterally varying structure inside the fluid core by computing the topography on constant-potential surfaces within the core. We conclude that this structure is not likely to be a complicating factor when using nutation and Earth tide observations to estimate the flattening of the core-mantle boundary. Finally, we compute the inner core-outer core (icb) topography for loading inside the mantle and for loading inside the inner core. We show that in the first case, the icb topography is small and dominated by long wavelengths; in the second case, we conclude that, if the density heterogeneities inside the inner core are two orders of magnitude smaller than in the mantle, the icb topography can be about 100 m peak-to-peak.
Light ion concentrations and fluxes in the polar regions during magnetically quiet times

Ion concentrations, flow velocities, and fluxes, measured by the ion mass spectrometer on the Isis 2 satellite for periods around the solstices and equinoxes of 1971 and 1972, have been used in a study of the polar wind morphology during magnetically quiet times. The results confirm the major tenets of polar wind theories; namely, that an upward flow of both H+ and He+ ions exists at all times over the entire polar region; H+ fluxes are of the order of 108 ions/cm2 s in both summer and winter polar regions. O+ is the dominant ion specie at 1400-km altitude in regions of strong H+ flows, and H+ is depleted over the entire region where the polar wind flows. H+ fluxes tend to be lower in winter than in summer, whereas He+ fluxes are a factor of 10 higher in winter and tend to follow the neutral helium concentration near the F2 maximum. The latter agree well with model calculations of flux in the winter but lie above the model values by a factor of 2 in the summer. H+ fluxes also agree well with ion flow models.
Scaling law between corner frequency and seismic moment of microearthquakes: Is the breakdown of the cube law a nature of earthquakes?

The corner frequency, fC, and the seismic moment, M0, of microearthquakes (local magnitude from −1.3 to 1.3) are estimated from the records of sensors located at an 1800‐m‐deep borehole at the Nojima fault, central Japan. The digital waveforms of each event are recorded with two different sampling rates, 10 kHz and 100 Hz. The source parameters estimated from high‐sampling data satisfy a relationship of M0 ∝ fC−3, corresponding to a constant stress drop law, while those calculated from low‐sampling data follow a relationship of M0 ∝ fC−4. A lack of high frequency components in the 100 Hz sampling data seem to be obvious, indicating that the value of fC and M0 are incorrectly estimated and the relationship of M0 ∝ fC−4 is an artifact caused by the limited frequency band of these data. The scaling relationship of M0 ∝ fC−3 is, thus, also valid for microearthquakes, and the breakdown of the constant stress drop law, reported in the literature, is not well founded.
Application of the cBΩ model to the calculation of diffusion parameters of Si in silicates

Silicon diffusion in major mantle minerals plays an important role in understanding a number of physical and chemical processes in the Earth's interior. Inspection of existing experimental data reveals linear compensation law between the preexponential factors and the activation energies for Si diffusion in various minerals by focusing on those of geophysical interest. On the basis of the observed compensation relationship, here we propose a thermodynamic model, the so‐called cBΩ model that interconnects point defect parameters with the bulk properties to reproduce the Si self‐diffusion coefficients in different rock‐forming minerals. When the uncertainties are considered, the predicted results show that the temperature and pressure dependences of self‐diffusion coefficients concur with existing experimental data and theoretical calculations in most cases.
Breaking the chains: Advancements in antiviral strategies to combat Nipah virus infections

Nipah virus (NiV) is a highly pathogenic zoonotic virus that has caused several outbreaks with high fatality rates in humans and animals, thus, requiring a “One Health” approach. No specific treatment or vaccine is available for NiV infection, making the development of effective antiviral agents against this virus a critical research priority. In recent years, significant efforts have been made to identify and develop antiviral agents targeting the various stages of NiV pathogenesis. This review comprehensively discusses current research on antiviral agents against NiV. The promising results obtained with several compounds, including repurposed drugs, nucleoside analogs, phytochemicals, and multi-target inhibitors, are also highlighted. Developing effective antiviral agents against NiV remains a major challenge; however, recent advances in understanding the mechanisms of NiV pathogenesis and identifying potential targets for antiviral agents have provided hope for the future. Further research is required to identify and optimize antiviral agents with broad-spectrum activity against NiV and other related viruses.
Influence of Hotel Green Energy Practices on Competitive Advantage

The hotel industry is one of the major economic segments to achieving the Kenya Vision 2030. The hotel sector is a significant contributor to GDP and a source of employment for thousands of Kenyans. However, many hotels have relied much on the quality of products as an avenue to achieving competitive advantage, disregarding the role of green energy influence on competitive advantage in the hotel sector. This study aimed to determine the influence of green energy practices on the competitive advantage of tourist hotels in Nyeri County. A cross-sectional survey design was employed to guide the study. The study population was 170 tourist hotels and nine government officers concerned with tourism. Data was collected using semi-structured questionnaires and interview schedules. A reliability test was employed to measure the questionnaire's consistency and adequacy by using the Cronbach alpha coefficient technique with only items of 0.70 and above selected. Qualitative data were analysed using thematic content analysis. A p-value of 0. 005 determined the overall significance of the study. The study revealed that green energy conservation practices and competitive advantage are significantly and positively related (β= 0.838, p=0.000). The study found that every unit change in energy conservation practices leads to an increase in competitive advantage. The study concluded that green energy practices reduce hotel operation costs, leading to a competitive advantage.

Integrating Human-Computer Interaction Development into the Systems Development Life Cycle: A Methodology

Incorporating a human computer interaction (HCI) perspective into the systems development life cycle (SDLC) is necessary to information systems (IS) success and, in turn, to the success of businesses. However, modern SDLC models are based more on organizational needs than human needs. The human interaction aspect of an information system is usually considered far too little (only the screen interface) and far too late in the IS development process (only at the design stage). Thus, often a gap exists between satisfying organizational needs and supporting and enriching human users. This problem can be addressed by carefully integrating HCI development into the SDLC process to achieve a truly human-centered IS development approach. This paper examines the roles of HCI in systems development, justifies the importance of considering HCI through out the entire systems development life cycle, presents a methodology for human-centered IS development, and demonstrates how to apply this methodology to develop human-centered information systems.
Ulceronodular syphilis (lues maligna praecox) in a person newly diagnosed with HIV infection

In this case of secondary syphilis, pustular lesions progressed rapidly to painful ulcerative lesions in a patient with early HIV infection. This rapidly progressive form of early syphilis has historically been called lues maligna praecox, a severe form of noduloulcerative secondary syphilis. Serologic tests for syphilis were positive and biopsy showed forms consistent with Treponema pallidum in the lesions. This case demonstrates how HIV infection may affect presentation and diagnosis of secondary syphilis.
DISPERSIVE BODY WAVES—AN EXPERIMENTAL STUDY

Body‐wave dispersion is documented for a three‐dimensional case using the pulse propagation experiment in the Pierre Shale conducted by McDonal et al. (1958) and for a two‐dimensional case using ultrasonic pulse propagation in a Plexiglas plate. The magnitude of the dispersion for a five‐octave frequency band was only about two to three percent but easily observable by using Fourier‐analysis techniques. Body‐wave dispersion is shown to be predictable from the attenuation coefficient by following the causal transform technique of Futterman (1962). The principle of superposition is shown to be applicable for the prediction of the pulse anywhere in a medium if the complex propagation constant is known and if the pulse is known at one location. Pulse‐form prediction based on the attenuation coefficient alone is inadequate, while prediction based on attenuation and dispersion is in good agreement with observed results.
partial complex seizures: CT and MR imaging Intracerebral gangliogliomas in patients with

The clinical and radiologic findings in 19 patients with partial complex seizures and surgically proved intracerebral gangliogliomas were reviewed to characterize the radio logic features of these lesions. The CT and MR findings were not specific. On CT the gangliogliomas can be hypodense with no enhancement and they often have calcifica tions. On MR these tumors have a wide variety of signals. In five of our cases the tumor had a high-intensity signal with a cystlike component on proton density-and T2-weighted images. In five cases the lesion had an inhomogeneously intense signal on proton density-weighted images and high signal intensity on T2-weighted images. The tumor had high-intensity signal on both proton density-and T2-weighted images in four patients. Finally, in two cases the MR findings were normal. We recommend MR as the examination of choice for patients with partial complex seizures because it allows an artifact-free evaluation of the temporal region. However, CT should also be performed in order to recognize calcifications that may be missed on the MR examination.
Finally, Nebraska: A Synthetic Control Analysis of Legislative Finally, Nebraska: A Synthetic Control Analysis of Legislative Structure Structure

I estimate the impact of Nebraska’s 1937 switch from a bicameral to a unicameral legislature on state-level government expenditures. Using the synthetic control method I create a counterfactual Nebraska from a weighted-average of other potential control states and compare spending in this “synthetic Nebraska” to spending in the real Nebraska. Relative to the synthetic control, Nebraska experiences a sharp decrease in expenditures per capita immediately following the switch to a unicameral legislature, however, the diﬀerence appears to diminish over time. Placebo tests show that if the change in Nebraska’s legislative structure were randomly assigned amongst the sample of states, and legislative structure had no real impact on spending, the likelihood of obtaining a treatment eﬀect estimate as large as Nebraska’s would be 0.0213. While the initial drop in expenditures per capita lends support to the theory that bicameralism, by requiring more veto players, is associated with higher levels of government spending, the fact that the diﬀerence between Nebraska and synthetic Nebraska diminishes suggests that legislators are able to circumvent this constraint.
Decidability of Distributive ℓ -pregroups

We show that every distributive lattice-ordered pregroup can be embedded into a functional algebra over an integral chain, thus improving the existing Cayley/Holland-style embedding theorem. We use this to show that the variety of all distributive lattice-ordered pregroups is generated by the single functional algebra on the integers. Finally, we show that the equational theory of the variety is decidable.
