Influence of Radio Music Broadcasting On COVID-19 Vaccine Acceptance among Women in Rural Communities of Delta State, Nigeria

Music broadcasting is an essential feature of radio communication, and musical lyrics constitute an essential component of public health-related media campaigns. This study explores the influence of radio music broadcasting on the perception, attitudes and behaviour of women towards COVID-19 vaccine acceptance in twelve rural communities of Delta State, Nigeria. Anchored on the Theory of Reasoned Action/Behaviour, the study utilises the survey research design to critically analyse responses obtained from 400 respondents drawn through multistage sampling. Findings showed that radio is a major source of information on COVID-19 vaccines among the respondents, and radio music broadcasting has a significant positive influence on the respondents’ perception, attitude and behaviour towards COVID-19 vaccine acceptance and willingness to be vaccinated. Specifically, the findings suggest that increased exposure to radio music broadcasting on COVID-19 vaccine tends to enhance the respondents’ overall acceptance of the vaccine as well as their willingness to get vaccinated. The study recommends the need for improved access to radio music broadcasting programmes in rural communities and the development of more suitable programming contents to promote the acceptance of recommended public health behaviours among rural dwellers.
The origin of tetraradial symmetry in cnidarians

Serially arranged sets of eight septa-like structures occur in the basal part of phosphatic tubes of Sphenothallus from the early Ordovician (early Floian) Fenxiang Formation in Hubei Province of China. They are similar in shape, location and number, to cusps in chitinous tubes of extant coronate scyphozoan polyps, which supports the widely accepted cnidarian affinity of this problematic fossil. However, unlike the recent Medusozoa, the tubes of Sphenothallus are flattened at later stages of development, showing biradial symmetry. Moreover, the septa (cusps) in Sphenothallus are obliquely arranged, which introduces a bilateral component to the tube symmetry. This makes Sphenothallus similar to the Early Cambrian Paiutitubulites, having similar septa but with even more apparent bilateral disposition. Biradial symmetry also characterizes the Early Cambrian tubular fossil Hexaconularia, showing a similarity to the conulariids. However, instead of being strictly tetraradial like conulariids, Hexaconularia shows hexaradial symmetry superimposed on the biradial one. A conulariid with a smooth test showing signs of the ‘origami’ plicated closure of the aperture found in the Fenxiang Formation supports the idea that tetraradial symmetry of conulariids resulted from geometrical constrains connected with this kind of closure. Its minute basal attachment surface makes it likely that the holdfasts characterizing Sphenothallus and advanced conulariids are secondary features. This concurs with the lack of any such holdfast in the earliest Cambrian Torellella, as well as in the possibly related Olivooides and Quadrapyrgites. Bilaterally arranged internal structures in polyps representing probably the oldest medusozoans support the suggestions based on developmental evidence that the ancestor of cnidarians also was a bilaterally symmetrical animal. This is one more example of fossil data that strictly fit the molecular phylogenetic evidence but not necessarily morphology-based zoological interpretations.
Spatial coherence structure and attenuation of the Lg phase, site effects, and the interpretation of the Lg coda

Analyses at seismic arrays showed that the intersensor coherence in the early, most energetic part of the Lg wave train decreases faster perpendicularly to the direction of propagation than parallel to it. This indicates a significant amount of forward scattered energy with a spread in direction of arrival. Following this part of the Lg wave train, the intersensor coherence rapidly decreases, indicating that most of the energy arriving is omnidirectional. The amplitude levels of this part of the wave train are too high to be explainable by the single scattering mechanism used in the interpretation of coda Q. The energy in the late coda is also often too high by this standard. The strong dependence of the Lg envelope shapes on local geology also indicates that the Lg coda is generated by processes much more complex than the scattering of primary Lg into waves of the same modal composition, and mode conversions play a significant role in the scattering process.
Impact of lifestyle and psychological resilience on survival among the oldest-old in China: a cohort study

Introduction Healthy lifestyles and psychological resilience are important factors influencing the life expectancy of the oldest-old (≥80 years). Stratified by urban and rural groups, this study used a 10-year cohort to examine the mechanism of lifestyle and psychological resilience on the survival of the oldest-old in China. Methods This study used the China Longitudinal Healthy Longevity Survey datasets spanning from 2008 to 2018, and 9,250 eligible participants were included. The primary outcome variable was all-cause mortality, and independent variables included healthy lifestyle index and psychological resilience. Six covariates were included in the survival analysis and moderation-mediation model, such as gender and annual household income. Results This study found that the oldest-old with five healthy lifestyles had the longest survival time, averaging 59.40 months for urban individuals and 50.08 months for rural individuals. As the lifestyle index increased, the survival rate significantly increased. The Cox regression showed that for the urban oldest-old, the lifestyle index served as a protective factor for survival outcomes. However, this effect lost statistical significance among rural oldest-old individuals. For urban oldest-old individuals, psychological resilience significantly mediated and moderated the effect of the lifestyle index on survival status, but the moderating effect was not statistically significant for the rural ones. Discussion Overall, healthy lifestyles and psychological resilience can be effective in enhancing the survival of the oldest-old, and there are differences between urban and rural population, so different interventions should be adopted for urban and rural areas to achieve longer life in China.
Effect of Pulsed Electric Field Technology on the Composition and Bioactive Compounds of Black Soldier Fly Larvae Dried with Convective and Infrared–Convective Methods

In recent years, an increasing interest has been shown in alternative food sources. Many studies are focused on the use of insects. The aim of this study was to investigate the changes in the chemical and thermal properties of black soldier fly larvae influenced by the pulsed electric field (PEF) and convective (CD) or infrared–convective (IR-CD) drying techniques. Examinations of the basic chemical composition, properties of extracted fat (fatty acid composition, acid and peroxide values, and oxidative stability), total polyphenol content, antioxidant activity, allergen content, and thermogravimetric analysis (TGA) were performed. Generally, the results showed that dried black soldier fly larvae are a good source of protein and fat, up to 33% and 44%, respectively. The fat extracted from the dried insects consisted mainly of saturated fatty acids (above 75%), in particular lauric acid (C12:0). A good oxidative stability of the fat was also observed, especially from samples dried with the IR-CD method. The convective drying technique allowed for better preservation of protein content compared to samples dried with the IR-CD method. Nevertheless, samples treated with PEF were characterized by significantly lower protein content. The samples after PEF pretreatment, with an intensity of 20 and 40 kJ/kg and dried with the IR-CD method, were represented by a significantly higher total polyphenol content and antioxidant activity. Furthermore, in most cases, the convectively dried samples were characterized by a higher allergen content, both crustaceans and mollusks. Taking into account all of the investigated properties, it can be stated that the samples without treatment and those that were PEF-treated with an intensity of 40 kJ/kg and dried with the infrared–convective method (IR-CD) were the most rewarding from the nutritional point of view.
Effects of pathogen reproduction system on the evolutionary and epidemiological control provided by deployment strategies for two major resistance genes in agricultural landscapes

Abstract Resistant cultivars are of value for protecting crops from disease, but can be rapidly overcome by pathogens. Several strategies have been proposed to delay pathogen adaptation (evolutionary control), while maintaining effective protection (epidemiological control). Resistance genes can be (i) combined in the same cultivar (pyramiding), (ii) deployed in different cultivars sown in the same field (mixtures) or in different fields (mosaics), or (iii) alternated over time (rotations). The outcomes of these strategies have been investigated principally in pathogens displaying pure clonal reproduction, but many pathogens have at least one sexual event in their annual life cycles. Sexual reproduction may promote the emergence of superpathogens adapted to all the resistance genes deployed. Here, we improved the spatially explicit stochastic model landsepi to include pathogen sexual reproduction, and we used the improved model to investigate the effect of sexual reproduction on evolutionary and epidemiological outcomes across deployment strategies for two major resistance genes. Sexual reproduction favours the establishment of a superpathogen when single mutant pathogens are present together at a sufficiently high frequency, as in mosaic and mixture strategies. However, sexual reproduction did not affect the strategy recommendations for a wide range of mutation probabilities, associated fitness costs, and landscape organisations.
Design and Metrological Characterization of a Digitizer for the Highest Precision Magnet Powering in the High Luminosity Large Hadron Collider

A new digitizer, the HPM7177, which is a fundamental component of the signal chain for high precision measurement of particle accelerator magnet currents, is presented. It was designed to meet the unprecedented performance requirements for new 14 kA and 18 kA power converters (PCs) for the High Luminosity Large Hadron Collider (HL-LHC) project at CERN, particularly in terms of low-frequency noise and stability. To determine accurately the performance of the digitizer, which is on a similar level as state-of-the-art classical metrological equipment, we carried out a thorough characterization using the programmable Josephson voltage standard (PJVS) at PTB-Braunschweig. At its nominal full scale of <inline-formula> <tex-math notation="LaTeX">$\mathrm {10~\, \text {V}}$ </tex-math></inline-formula>, the digitizer has a white noise level of <inline-formula> <tex-math notation="LaTeX">$ < \mathrm {175~\, \text {n} \text { V} ~\text {Hz}^{-1/2}}$ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$1/f$ </tex-math></inline-formula> noise floor <inline-formula> <tex-math notation="LaTeX">$\approx \mathrm {7e{-8}~\, \text {V}}$ </tex-math></inline-formula>, and a 12-h peak-to-peak stability better than 2 <inline-formula> <tex-math notation="LaTeX">$\mu \text{V}$ </tex-math></inline-formula> or <inline-formula> <tex-math notation="LaTeX">$\mathrm {0.2~\,}$ </tex-math></inline-formula>parts per million (ppm). The static non-linearity from <inline-formula> <tex-math notation="LaTeX">$\mathrm {0~\, \text {V}}$ </tex-math></inline-formula> to <inline-formula> <tex-math notation="LaTeX">$+\mathrm {10~\, \text {V}}$ </tex-math></inline-formula> is <inline-formula> <tex-math notation="LaTeX">$ < \mathrm {1~~}$ </tex-math></inline-formula>ppm and remains stable to <inline-formula> <tex-math notation="LaTeX">$\approx \mathrm {e{-7}~l}$ </tex-math></inline-formula>evel in <inline-formula> <tex-math notation="LaTeX">$\mathrm {12~\,months}$ </tex-math></inline-formula>. The digitizer operates at a fixed rate of <inline-formula> <tex-math notation="LaTeX">$\mathrm {10~\, \text {k} Samples / \text {s} }$ </tex-math></inline-formula> and can be synchronized externally. Besides qualifying HPM7177 for its application, the characterization reveals important aspects of its operation, as well as some performance limitations.
Masked Second-Order Pooling for Few-Shot Remote-Sensing Scene Classification

Few-shot remote-sensing scene classification (FSRSSC) is the task of categorizing remote-sensing images (RSIs) with insufficient labeled samples. This task becomes particularly challenging due to low intraclass similarity and high interclass similarity in RSIs. To overcome these challenges, we introduce a novel masked second-order pooling (MSoP) module to exploit the masked second-order features, enhancing feature representation and classification performance for FSRSSC. The MSoP module comprises two key components: a learnable DropBlock (LDB) and a compressed second-order pooling (CSoP). The LDB selectively masks discriminative regions in feature maps, effectively alleviating the low intraclass similarity problem. On the other hand, the CSoP enhances second-order statistics by computing and aggregating channel-wise similarity, thereby reducing the impact of interclass similarity. We construct an MSoP-Net based on the proposed MSoP module. Experimental results demonstrate its superior performance on two widely used datasets, that is, NWPU-RESISC45 and UCM.

Terahertz bow-tie diode based on asymmetrically shaped AlGaN/GaN heterostructures

Asymmetrical shaping of AlGaN/GaN heterostructures containing a conductive layer of two-dimensional electron gas (2DEG) was used for the development of bow-tie (BT) diodes for room temperature terahertz (THz) detection. Considering operation of the THz BT diode in the unbiased mode as preferable for practical applications, we investigated the diodes with an obvious asymmetry of IV characteristics, which was found to be more pronounced with the decrease of an apex width, resulting in the sensitive THz detection. A nonuniform heating of carriers in a metalized leaf of the BT diode was attributed as the main mechanism that caused the rectification of THz waves. The responsivity and noise-equivalent power (NEP) at the fundamental antenna frequency of 150 GHz were up to 4 V/W and 2 nW/√Hz, respectively. Such high sensitivity of BT diodes allowed us to measure for the first time the response spectrum of the asymmetric BT antenna demonstrating fundamental and higher order resonances in good agreement with finite-difference time-domain simulation data in a broad spectrum range. The detailed investigation of the lowand high-frequency noise characteristics of AlGaN/GaN BT diodes revealed that only thermal noise needs to be considered for the unbiased operation, the value of which was relatively low due to a high density of 2DEG enabling low resistivity values. Moreover, we observed that the responsivity of BT diode scales with its resistance, revealing that tapering of the diode apex below a few microns could be ineffective in applications which require low NEP values.
Occlusal Contact Surface Changes and Occlusal Force Distribution Between Vacuum-Formed Retainers and Other Retainers: A Systematic Review

The present systematic review was done to assess the available literatures on changes in the number of occlusal contacts (NOC), occlusal contact surface areas, and occlusal force distribution (OFD) with vacuum-formed retainers (VFRs) or clear overlay retainers during retention and to compare them with other retainers. Six electronic databases (Web of Science, Scopus, PubMed, Cochrane Library, Lilacs, and Google Scholar) were searched. Randomized controlled trials (RCTs) and controlled clinical trials (CCTs) reporting on occlusal contact changes with VFRs were included. A total of nine articles were included in this review: three RCTs, five prospective controlled trials (PCTs), and one CCT. The Cochrane risk of bias tool and ROBINS-I tool were used for risk of bias assessment. The three RCTs showed moderate risk of bias, and out of five CCTs, four showed low risk of bias, and one showed moderate risk of bias. One CCT showed a low risk of bias in the ROBINS-I tool. Two out of four studies reported improved occlusal surface area (OSA) with VFRs when assessed at the end of six months and 12 months; one out of four studies reported improved NOC; and one study reported a decrease in OFD anteriorly and an increase in OFD posteriorly after two months of retention. On comparison between the groups, the other retainer groups showed more NOCs compared to VFRs. The limited available evidence suggests an increase in OSA and no change in NOCs and OFD with VFRs during retention. No significant differences between VFRs and other retainers for OSA and OFD were noted, and more NOCs were noted for other retainer groups.
Assessment of Heavy Metals Concentration in Different Organs of Labeo rohita and Cyprinus carpio

The current study was conducted to assess the concentration of heavy metals in rohu (Labeo rohita) and common carp (Cyprinus carpio). A total of three sites namely Rawal Lake Islamabad, Head Balloki, and a private fish farm in Muridke were selected. Fish were dissected and tissues from the liver, kidneys, gills, and muscles were separated. Chemical digestion of samples was carried out with aqua regia. Three metals namely chromium (Cr), cadmium (Cd), and mercury (Hg) were detected by using atomic absorption spectroscopy in the labs of Pakistan Council of Scientific and Industrial Research (PSCIR), Lahore, Pakistan. All metals were found at a higher level in different tissues of both the fish species. The overall trend of metals in the two fish species namely rohu and carp was recorded as Hg > Cd > Cr. It was observed that the level of Hg remained very high as compared to other metals. Statistical analysis was performed using one-way ANOVA and significant differences at p < 0.001 were noticed for the metals in different organs. While, independent sample t test showed non-significant differences at p > 0.483 between the two fish species. The liver was found to have the highest metal load, followed by the kidneys and gills. The metal load was above the permissible limit set by World Health Organization (WHO). However, the heavy metals concentration in muscles was below the permissible limit. It was noticed that heavy metal contamination was higher in Rawal Lake as compared to the private fish farm. It was concluded that contaminated water bodies are affecting the exposed organisms. So, there is a need to save them from pollutants for the best survival of aquatic life.
Design and Optimization of a Small Horizontal Axis Wind Turbine Blade using QBlade

One of the most significant sources of renewable energy in the world is wind energy, and the fastest growing because of its unique advantages, such as cheap costs, and its friendliness to the environment, as it is a natural resource that is not subject to human control. Based on the detailed wind speed data for the selected site, the type of wind turbine is determined. In this research paper, QBlade software was used to analyze and simulate the horizontal axis wind turbine blades in order to increase the power coefficient. Also, it was analyzed the behavior deeply and the performance of the wind blade based on the Blade Element Momentum theory (BEM) to simulate the Horizontal Axis Wind Turbines (HAWTs). The effect of the twist angle and chord length of three horizontal axis wind turbine blades on the behavior and performance of wind turbines has been investigated. It used two airfoils (SD7062) and (S8066), each with a 1.5 -meter- long blade divided into 12 sections. The validity of the results of analyses and optimization was proved using the QBlade software. It was found that maximum values of the ratio (CL/CD) occurred when the angles of attack were 6.5 and 4, corresponding to the airfoils (SD7062) and (S8066), respectively. Based on the achieved analysis, the tip speed ratio (TSR) was equal to 7.
Urine volume of non-lactating dairy cows in late gestation fed forage based diets in winter

Quantitative information on urine volume of dairy cows fed winter forages is required to accurately evaluate nitrate leaching risks on these diets. Thirty-two Friesian x Jersey non-lactating, pregnant dairy cows were fed either 10 kg DM of fodder beet with 5.6 kg DM of ryegrass baleage or 16.4 kg DM of kale with 6.4 kg of oat silage. Cows were fitted with a urine meter for 24 to 72 hours to record the frequency and volume of urine events. Daily urine volume (28 ± 3 L/cow/day), frequency (9 ± 0.89 events/cow/day), and event volume (3.2 ± 0.3 L/event) were not significantly different between fodder beet and kale treatments. This was despite respective differences in total apparent water (51 vs. 70 L/cow/day, ± 2, P<0.001) and nitrogen (N) intake (231 vs. 488 g N/cow/ day, ± 9.4, P<0.001). In this study, water consumption and N intake did not appear to be linked with urine volume of dairy cows when two different forage diets were compared.
Is tourism live streaming a double-edged sword? The paradoxical impact of online flow experience on travel intentions

ABSTRACT This study used a mixed method to investigate the dual effects of the flow experience provided by tourism live streaming (TLS) on tourists’ travel intentions and how such effects vary across different types of destinations. The results reveal that, in contrast to managers’ predictions, while flow experience from TLS may boost offline travel through inspiration, it can also increase tourists’ concern for substitutability and thereby reduce their travel intentions. Live streamers’ expertise positively moderates the positive effect of flow experience on inspiration. Furthermore, the negative impacts are more salient in highly reputable cultural destinations and natural destinations with limited reputation.
