This study aims to establish a rapid identification method based on the Proofman-LMTIA technique for distinguishing between Panax quinquefolium and Panax ginseng. By targeting specific 18S rDNA sequences, suitable primers and Proofman probes labeled FAM or JOE were designed for LMTIA. Initially, single-species-primer Proofman-LMTIA assays were performed separately for each ginseng type to optimize reaction temperature, assess sensitivity and specificity, and determine the detection limit. Subsequently, both sets of primers and their corresponding probes were combined in the same reaction system to further optimize reaction conditions, evaluate sensitivity, and assess stability. Finally, the developed Proofman-duplex-LMTIA technique was employed to detect P. quinquefolium and P. ginseng slices available in the market. Single-plex Proofman-LMTIA assays revealed that the optimal reaction temperature for both P. quinquefolium and P. ginseng was 62 °C. The sensitivity was as low as 1 pg/μL, with a detection limit of 0.1%, and both showed excellent specificity. The optimal temperature for Proofman-duplex-LMTIA assays was 58 °C. This method could simultaneously identify P. quinquefolium and P. ginseng. Testing 6 samples of P. ginseng and 11 samples of P. quinquefolium from the market resulted in a 100% positive rate for all samples. This study successfully established a rapid, simple, sensitive, and specific Proofman-duplex-LMTIA identification method for P. quinquefolium and P. ginseng. It provides an effective means for quality control of P. quinquefolium, P. ginseng, and related products.

Supercritical fluid extraction (SFE) is an innovative green technology for the extraction of phytochemicals from plants. Therefore, this study aimed to evaluate the application of SFE and to optimize the extraction conditions of the Thai herbal formula, Kleeb Bua Daeng (KBD). A Box–Behnken design (BBD) with response surface methodology (RMS) was used to determine the effect of the extraction time (30–90 min), temperature (30–60 °C), and pressure (200–300 bar) on response variables including the extraction yield, total phenolic content (TPC), total flavonoid content (TFC), total carotenoid content (TCC), and total anthocyanin content (TAC) of the KBD formula. The highest percentage extraction yield (3.81%) was achieved at 60 °C, 300 bar, and 60 min of the extraction time. The highest TPC (464.56 mg gallic acid equivalents/g extract), TFC (217.19 mg quercetin equivalents/g extract), and TCC (22.26 mg β-carotene equivalents/g extract) were all achieved at 60 °C, 250 bar, and 90 min of the extraction time. On the contrary, it was not possible to quantify the total anthocyanin content as anthocyanins were not extracted by this method. The results indicated that SFE-CO2 is a suitable method of extraction for a green recovery of phytochemicals with low and moderate polarity from the KBD formula.

Diagnosing neurocysticercosis (NCC) is difficult due to its variable clinical presentations and the different imaging techniques used to detect brain damage. This study aimed to evaluate the use of cerebrospinal fluid serology and PCR for diagnosing biological neurocysticercosis in a non-endemic country. We tested samples from patients living in France with suspected NCC and confirmed that 45 of the patients presented with the disease. A total of 89% of patients had previously traveled to countries where the disease was endemic. The sensitivity of Western blots compared to ELISA was not significantly different (80% vs. 60%) (p > 0.05), and neither was the sensitivity of Western blots vs. PCR (78% vs. 56%) (p > 0.05). The PCR sensitivity was 78% and 47% in definitive NCC and in probable NCC. PCR tests using cerebrospinal fluid should be considered as a diagnostic criterion for identifying NCC.

Advances in the knowledge of the pathogenesis of SARS-CoV-2 allowed the survival of COVID-19 patients in intensive care units. However, due to the clinical characteristics of severe patients, they resulted in the appearance of colonization events. Therefore, we speculate that strains of Candida spp. isolated from COVID-19 patients have virulent genetic and phenotypic backgrounds involved in clinical worsening of patients. The aim of this work was to virutype Candida spp. strains isolated from colonized COVID-19 patients, analyze their genomic diversity, and establish clonal dispersion in care areas. The virulent potential of Candida spp. strains isolated from colonized COVID-19 patients was determined through adhesion tests and the search for genes involved with adherence and invasion. Clonal association was done by analysis of intergenic spacer regions. Six species of Candida were involved as colonizing pathogens in COVID-19 patients. The genotype analysis revealed the presence of adherent and invasive backgrounds. The distribution of clones was identified in the COVID-19 care areas, where C. albicans was the predominant species. Evidence shows that Candida spp. have the necessary genetic tools to be able colonize the lungs, and could be a possible causal agent of coinfections in COVID-19 patients. The detection of dispersion of opportunistic pathogens can be unnoticed by classical epidemiology. Epidemiological surveillance against opportunistic fungal pathogens in COVID-19 patients is an immediate need, since the findings presented demonstrate the potential virulence of Candida spp.

Published: September 2023

The growth of four commercial biocontrol agents (BCAs: Bacillus amyloliquefaciens (BAD), Aureobasidium pullulans (APD), Metschnikowia fructicola (MFN), and Trichoderma atroviride (TAS)) was evaluated using turbidimetric assays on artificial substrates mimicking the chemical berry composition at four stages: pea-sized berries, veraison, softening, and ripe berries. The response of BCA growth differed among BCAs. Subsequently, the BCAs’ population size was assessed after 1 to 13 days of incubation on the substrate mimicking ripe berries at 15 to 35 °C. The population size of BAD increased with temperatures, while that of MFN decreased; the population sizes of APD and TAS showed bell-shaped patterns with lower growth at 15 or 35 °C. Finally, the BCAs were applied to ripe berries and then incubated at 15 to 30 °C. After 1 to 13 days, the berries were inoculated with B. cinerea and incubated for 7 days, after which the BCA control efficacy was assessed. The highest control was observed at 25 °C for BAD and APD, at 15 to 20 °C for MFN, and at 25 to 30 °C for TAS. The results confirm that the plant substrates and temperature affect the population size of the BCA following application; temperature also affects the preventative efficacy of BCA against B. cinerea.

Published: September 2023

The antioxidant activity (AA) of hop extracts obtained from different hop genotypes (n = 14) was studied. For comparison, the purified β-acids-rich fraction and α-acids-with-β-acids-rich fraction were also used to test the antioxidative potential. The AA of purified hydroacetonic hop extracts was investigated using the Ferric Reducing Ability of Plasma (FRAP), Oxygen Radical Absorption Capacity (ORAC) and Intracellular Antioxidant (IA) methods. The FRAP values in different hop genotypes ranged between 63.5 and 101.6 μmol Trolox equivalent (TE)/g dry weight (DW), the ORAC values ranged between 1069 and 1910 μmol TE/g DW and IA potential values ranged between 52.7 and 118.0 mmol TE/g DW. Significant differences in AA between hop genotypes were observed with all three methods. AAs were determined using three different methods, which did not highly correlate with each other. We also did not find significant correlations between AA and different chemical components, which applies both to AA determined using individual methods as well as the total AA. Based on this fact, we assume that the synergistic or antagonistic effects between hop compounds have a more pronounced effect on AA than the presence and quantity of individual hop compounds.

Published: September 2023

The responses of rare plants to environmental stressors will determine their potential to adapt to a rapidly changing climate. We used a common garden approach to evaluate how six populations of the annual San Diego thornmint (Acanthomintha ilicifolia Lamiaceae; listed as endangered in the state of California and as threatened by the US Fish and Wildlife Service) from across the species range respond in terms of growth (biomass, height, and width) and reproduction (seed production, floral production, and next generation seed viability) to experimental differences in water availability. We found a significant irrigation-by-population interaction on the aboveground growth, wherein the differences in the magnitude and direction of treatment did not correlate directly with climate variables in natural populations. With respect to reproduction, the low-irrigation treatment produced more seeds per plant, more reproductive individuals, and a larger proportion of viable seed in most, but not all, populations. The seed production and the effect of irrigation on seed production correlated positively with rainfall at wild source populations. These results suggest that Acanthomintha ilicifolia responds to water limitation by creating more and higher-quality seed, and that plants locally adapted to a higher annual rainfall show a greater plasticity to differences in water availability than plants adapted to a lower annual rainfall, a finding that can inform the in situ demographic management and ex situ collection strategy for Acanthomintha ilicifolia and other rare California annuals.

Published: September 2023

In the aspect of food quality measurement, the application of image analysis has emerged as a powerful and versatile tool, enabling a highly accurate and efficient automated recognition and the quality classification of visual data. This study examines the feasibility of employing an AI algorithm on labeled images as a non-destructive method to classify surimi gels. Gels were made with different moisture (76–82%) and corn starch (5–16%) levels from Alaska pollock and Threadfin breams. In surimi gelation, interactions among surimi, starch, and moisture caused color and quality shifts. Color changes are indicative of structural and quality variations in surimi. Traditional color measuring techniques using colorimeter showed insignificant differences (p < 0.05) in color values and whiteness among treatments. This complexity hindered effective grading, especially in intricate formulations. Despite insignificant color differences, they signify structural changes. The Convolutional Neural Network (CNN) predicts the visual impact of moisture and starch on gel attributes prepared with different surimi species. Automated machine learning assesses AI algorithms; and CNN’s 70:30 training/validation ratio involves 400–700 images per category. CNN’s architecture, including input, convolutional, normalization, Rectified Linear Unit (ReLU) activation, and max-pooling layers, detects subtle structural changes in treated images. Model test accuracies exceed 95%, validating CNN’s precision in species and moisture classification. It excels in starch concentrations, yielding > 90% accuracy. Average precision (>0.9395), recall (>0.8738), and F1-score (>0.8731) highlight CNN’s high performance. This study demonstrates CNN’s value in non-destructively classifying surimi gels with varying moisture and starch contents across species, and it provides a solid foundation for advancing our understanding of surimi production processes and their optimization in the pursuit of high-quality surimi products.

Published: September 2023

Daqing Oilfield faces increasing reservoir heterogeneity after years of polymer flooding, limiting further enhanced oil recovery. A novel preformed particle gel (PPG) was developed by Daqing Oilfield due to the limited profile control ability of polymer flooding. The preformed particle gel possesses strong deformation ability and the ability to pass through pore throats. The PPG was developed considering the in situ reservoir conditions and combined effects of plugging and flooding. Thus, a heterogeneous system was prepared by mixing polymers and the PPG. In this study, we measured the related properties of the system and assessed its profile control ability and oil displacement performance after polymer flooding. The experimental results demonstrate that typical polymer flooding cannot improve oil recovery under current reservoir conditions. Thus, deep profile control technology should be applied to remediate the highly heterogeneous reservoir issue. PPG can considerably increase the viscosity and stability of the system. The heterogeneous system has a strong plugging ability during the subsequent water flooding stage and is suitable to inject into the medium and high permeability layers. The water absorption profile of the core samples is significantly improved due to the impact of the PPG on the plugging of the layer with high permeability and the liquid flow direction. The system displays an excellent profile control effect in the core with a permeability ratio (high permeability/low permeability) of two under the conditions of a PPG concentration of 500 mg/L and an injection volume of 0.5 PV. In the oil displacement experiment, the recovery efficiency was raised by 16.56% using the polymer system, leading to significant swept volume increment and oil recovery improvement.

Published: September 2023

In the present study, two high-capacity experimental roller gin reclaimers, (a) a modified 3-saw cylinder stick machine (three-saw) and (b) a modified 2-saw cylinder gin stand feeder (700), were optimized with respect to reclaimer saw cylinder speed and carryover/seed ratio to minimize the seed and lint loss for both Pima and Upland cotton varieties and were compared to a conventional roller gin reclaimer operated by the ginning industry under standard conditions. Developed regression models adequately described the seed and lint loss phenomena during the reclaiming process. Surface plots indicated that the reclaimer saw cylinder speed and carryover/seed ratio impacted the seed and lint loss for both the 3-saw and 700 reclaimers. Under optimized conditions, the 700 reclaimer resulted in lower lint and seed loss compared to the 3-saw reclaimer when using Upland cotton. In the case of Pima cotton, under optimized conditions, the 3-saw reclaimer had 38% lower lint loss and 24% higher seed loss compared to the 700 reclaimer. The regression equations of both 3-saw and 700 reclaimers were further used to optimize the reclaimers in parallel arrangement to minimize the seed and lint loss. With Upland cotton, the economic loss was about 2.5 times greater with the conventional reclaimer compared to the 3-saw and 700 reclaimers ($15.97/bale loss for the conventional, $8.63 for the 3-saw, and $6.44 for the 700 reclaimers). With Pima cotton, the conventional reclaimer resulted in a lower economic loss ($3.44/bale) compared to the 700 reclaimer which had a loss of about $3.59/bale.

Authors: Wang Jiaping , Wang Chao , Mo Xiaoming , Wu Jie
Published: September 2023

This study aimed to investigate the feasibility of predicting nutritional parameters of the Korla pear using stress relaxation and creep parameters. A creep-recovery test and stress relaxation test were performed on the pear using a TA-XT plus Texture Analyzer. Creep and stress relaxation properties of the pear were characterized by a generalized Kelvin-Voigt model (six elements) and Maxwell model (seven elements), with coefficients of determination R2 of 0.992 and 0.998, respectively. The partial rheological parameters of the two models were significantly correlated with the total soluble solid (TSS), titratable acidity (TA), and solid acid ratio (RTT) of the pear (p < 0.05). Hence, the constructed stepwise multiple linear regression models can effectively predict three nutritional parameters (correlation coefficient r of prediction model > 0.7). The RMSE value of each nutritional parameters’ prediction model based on the creep parameters was smaller than that of the prediction models based on the stress relaxation parameters. Therefore, the models constructed using creep parameters are more stable and reliable for predicting the nutritional parameters of the Korla pear.
Preparation of Activated Carbon from Korean Anthracite: Simultaneous Control of Ash Reduction and Pore Development

Published: September 2023

Anthracite stands as a valuable precursor for carbon materials, owing to its high carbon content. However, producing activated carbon from anthracite presents significant challenges due to its elevated ash content (23–40 wt%) and crystalline nature. The high ash content not only fails to contribute to the activation process but also obstructs pore formation on the carbon surface. To address these challenges, this study explores the preparation of activated carbon from anthracite using KOH activation. This method demonstrates remarkable efficacy in enhancing reactivity beyond the inherent physical properties of anthracite. In contrast to physical activation, the utilization of KOH as a chemical agent substantially enhances the specific surface area, resulting in a production yield of 62% and a specific surface area that reaches up to 1596 m2/g at a KOH/anthracite weight ratio of 4.0. Moreover, rinsing the activated sample with tap water achieves an ash removal rate of about 37.9%, surpassing twice the rate achieved through acid pretreatment (67.0%). A noteworthy observation from this study is the substantial reduction in the content of major ash components, such as silicon (Si) and aluminum (Al), both of which are prominent constituents in anthracite ash. Following KOH activation, their levels decrease by approximately 54% to 65%, respectively. These findings highlight the potential of utilizing available anthracite, even with elevated ash content, as a superior carbon material. Fundamentally, the KOH activation method serves a dual purpose: it effectively reduces ash content and promotes pore creation within a highly alkaline environment. This dual advantage positions the method as a promising approach for the production of top-tier activated carbon.

Published: September 2023

Higher education has been facing many challenges due to factors including increased diversification, internationalization, massification, and the expansion of different forms of mobility, which are transforming the landscape of higher education towards “superdiversity”. These challenges are addressed within the framework of “inclusive education”, aiming to increase participation and foster a culture of welcome at higher education institutions. However, scholarly discussions on the ways these initiatives impact the lived experience of students who may face divergent and intersectional forms of exclusion, inequalities, tensions, and discrimination are limited. To address this gap, based on the experience of three participating universities in the European University of Post-Industrial Cities (UNIC) alliance, this paper aims to examine and reflect on the diversity and inclusion practices of the institutions, particularly those targeting concerns for international students with different profiles. Drawing on both existing and emergent data through an extensive case study analysis, the paper focuses on the scope and effectiveness of existing support mechanisms. It concludes that improving the experience of international students and promoting their inclusion at universities requires a combination of top-down and bottom-up mechanisms, as well as centralised and decentralised services. Systematic data collection using a range of engaged research tools also ensures that policies respond to real needs.

Published: September 2023

Burnout is a significant problem faced by professionals in the healthcare setting, and yet there is a lack of validated screening tools in the Spanish context. The present study examined the psychometric properties of a single-item measure of burnout (SIB) within a sample of 675 health professionals working at five centres in Spain, with the brief burnout questionnaire (BBQ) providing the main comparison measure. Predictive validity was acceptable, with high positive correlations between SIB, overall BBQ and the three BBQ dimensions. Construct validity, examined using confirmatory factor analysis, found that the SIB sufficiently covered the components of the three factors of burnout described by the BBQ and the components of the three dimensions of the burnout syndrome factor. Convergent validity was confirmed through significant negative correlations between SIB and good perceived health and job satisfaction. Acceptable cut-points were established. The Spanish-language SIB provides an acceptable and sensitive screening measure of burnout for use with health professionals.

Sulfonamide antibiotics in the environment not only disrupt the ecological balance but can also enter the human or animal body in various forms and cause harm. Therefore, exploring efficient methods to degrade sulfonamide antibiotics is crucial. In this study, we prepared biochar (BC) using corn straw, and TiO2/BC was obtained by doping different proportions of TiO2 into biochar with varying carbonization temperatures using the sol–gel method. Next, we investigated the degradation of sulfamethoxazole (SMX) in solution using the generated TiO2/BC under ultraviolet irradiation and studied the effects of various experimental parameters, such as the type of composite material, composite material addition, solution pH, and initial antibiotic concentration on SMX degradation. Under an initial SMX concentration of 30 mg/L, the composite with the best photocatalytic degradation performance was TiO2/BC-5-300 (i.e., 5 mL of TiO2 doping; 300 °C calcination temperature), with an addition amount of 0.02 g and a solution pH of 3. The degradation efficiency increased from 22.3% to 89%, and the most significant degradation effect occurred during the initial stage of photocatalytic degradation. In the TiO2/BC-5-300 treated SMX solution, the average rhizome length of bean sprouts was significantly higher than that of the untreated SMX solution and slightly lower than that of the deionized aqueous solution (3.05 cm < 3.85 cm < 4.05 cm). This confirmed that the photocatalytic degradation of SMX by the composite was effective and could efficiently reduce its impact on the growth of bean sprouts. This study provides essential data and theoretical support for using TiO2/BC in the treatment of antibiotic-contaminated wastewater.

The contexts where there are mining and agriculture activities are potential sources of risk to human health due to contamination by chemical mixtures. These contexts are frequent in several Colombian regions. This study explored the potential association between the frequency of micronuclei and pesticides and elements in regions with ferronickel (Montelibano, Córdoba) and gold (Nechí, Antioquia) mining, and a closed native mercury mine (Aranzazu, Caldas), with an emphasis in the potential effect of selenium as a potential chelator. A cross-sectional study was carried out with 247 individuals. Sociodemographic, occupational, and toxicological variables were ascertained. Blood and urine samples were taken for pesticide analysis (5 organophosphates, 4 organochlorines, and 3 carbamates), 68 elements were quantified in hair, and micronuclei were quantified in lymphocytes. The mixtures of elements were grouped through principal component analysis. Prevalence ratios were estimated with robust variance Poisson regressions to explore associations. Interactions of selenium with toxic elements were explored. The highest concentrations of elements were in the active mines. The potentially most toxic chemical mixture was observed in the ferronickel mine. Pesticides were detected in a low proportion of participants (<2.5%), except paraoxon-methyl in blood (27.55%) in Montelibano and paraoxon-ethyl in blood (18.81%) in Aranzazu. The frequency of micronuclei was similar in the three mining contexts, with means between 4 to 7 (p = 0.1298). There was great heterogeneity in the exposure to pesticides and elements. The “hormetic effect” of selenium was described, in which, at low doses, it acts as a chelator in Montelibano and Aranzazu, and at high doses, it can enhance the toxic effects of other elements, maybe as in Nechí. Selenium can serve as a protective agent, but it requires adaptation to the available concentrations in each region to avoid its toxic effects.

Published: September 2023

Since July 2022, the Yangtze River basin has experienced the most severe hydro-meteorological drought since record collection started in 1961, which has greatly affected the ecological environment of the Dongting Lake (DTL) basin. To investigate the effects of drought events on the eutrophication and phytoplankton community structure of DTL, the lake was sampled twice in August and September 2022 based on the water level fluctuations resulting in 47 samples. Furthermore, we combined the comprehensive trophic level index (TLI) and phytoplankton Shannon–Wiener diversity index (H) to characterize and evaluate the eutrophication status. The key influencing factors of the phytoplankton community were identified using redundancy analysis (RDA), hierarchical partitioning, and the Jaccard similarity index (J). Our results showed that the TLI of DTL changed from light–moderate eutrophication status (August) to mesotrophic status (September), whereas the H changed from light or no pollution to medium pollution. The phytoplankton abundance in August (122.06 × 104 cells/L) was less than that in September (351.18 × 104 cells/L) in DTL. A trend in phytoplankton community succession from Bacillariophyta to Chlorophyta and Cyanophyta was shown. The combination of physiochemical and ecological assessment more accurately characterized the true eutrophic status of the aquatic ecosystem. The RDA showed that the key influencing factors in the phytoplankton community were water temperature (WT), pH, nitrogen and phosphorus nutrients, and the permanganate index (CODMn) in August, while dissolved oxygen (DO) and redox potential (ORP) were the key factors in September. Hierarchical partitioning further indicated that temporal and spatial variations had a greater impact on the phytoplankton community. And the J of each region was slightly similar and very dissimilar, from August to September, which indicated a decreased hydrological connectivity of DTL during drought. These analyses indicated that the risk to the water ecology of DTL intensified during the summer–autumn drought in 2022. Safeguarding hydrological connectivity in the DTL region is a prerequisite for promoting energy flow, material cycle, and water ecosystem health.

Vibration Response of Manual Wheelchairs According to Loads, Propulsion Methods, Speeds, and Ground Floor Types
Authors: Larivière Ophélie , Chadefaux Delphine , Sauret Christophe , Thoreux Patricia
Published: September 2023

Manual wheelchair (MWC) users are daily exposed to vibration during propulsion. The impact of such exposure on the MWC user’s health has yet to be proven. To date, no agreement has been reached, presumably on the account of the wide variety of experimental parameters that need to be controlled. A possible solution relies on the implementation of a User/MWC model to point out the effect of propelling conditions (MWC loads, propulsion methods, speeds, and ground floor types) on the vibration exposure and eventually on the MWC user’s health. To feed such a model, the evaluation of the MWC vibration response during propulsion is required. Following a necessary MWC experimental modal analysis under laboratory conditions, this study presents the vibration response of an MWC under various propelling conditions. For each investigated condition, the identified set of modal parameters was provided and the effect on the MWC response to vibration at the User/MWC interfaces was highlighted. Results mostly underline that the response to vibration is highly dependent on the propelling conditions. The speed and the ground floor type greatly affect the vibration response: doubling speed and increasing ground surface roughness imply threefold and eightfold vibration levels, respectively. Finally, the main outcome is that an empty MWC or an MWC loaded with a dummy generates vibration outside the range measured for an MWC loaded with a human body, resulting in a lower frequency content and an almost two-fold vibration level increase. The findings of this study will help enhance the understanding of the health risks that wheelchair users encounter as a result of vibrations.

La sociedad de la información ha permitido universalizar, en gran medida, el acceso a la música clásica. Gracias a las nuevas tecnologías se han eliminado la mayoría de barreras geográficas y económicas para llevar este tipo de música a un nuevo público, que abarca potencialmente a toda la humanidad. Sin embargo, muchos de estos nuevos oyentes se encuentran con dificultades a la hora de decodificar el lenguaje y los recursos utilizados en gran parte del repertorio, especialmente el surgido a partir de las corrientes de vanguardia del siglo XX. Ante este escenario, el análisis musical se erige como una herramienta idónea para solventar estas dificultades y romper la última barrera de entrada a la música clásica. Pero para poder llegar a este nuevo público, el propio análisis debe democratizarse: centrarse en sus metodologías más accesibles y no ser víctima de los tecnicismos que aspira a decodificar. Esta democratización solo puede conseguirse observando las características del nuevo público y estudiando las distintas técnicas a disposición de los analistas para ofrecer las herramientas y metodologías adecuadas a los nuevos oyentes.

Interventions in reducing maternal mortality rates and infant mortality rates are not only carried out on pregnant women but must begin before pregnancy, namely on the prospective bride and groom by providing communication, information, education and reproductive health counseling as well as examinations for future bride and groom. Pre-marital counseling is a process of providing assistance by a professional to prospective husband and wife before carrying out marriage and providing provisions and instructions so that they can form a happy household life. The results of an initial study at Banggae 1 community Health centers on January-December 2022, 180 future bride and groom were counseled. Where among them who checked the pregnancy according to standards (KI) as many as 102 people, while the rest were not according to standards. This shows that there are still many future bride and groom who do not have standardized pregnancy checks. Based on these problems, the researcher is interested in examining how the influence of counseling of future bride and groom on mother's compliance in standardized prenatal checks. The purpose study is to determine the effect of counseling prospective brides on mother's compliance in standardized prenatal checks at Banggae 1 community Health centers. This study is quantitative method with a cross sectional study approach. It will be carried out in May 2023 with a population of 119 pregnant women who visited to Banggae 1 Majene Community Health Centers on January-April 2023 and sample of 54 people. The results showed that out of 54 respondents, 10 were in the category of respondents who did not receive counseling, while those who received counseling were 44 respondents. The conclusion is that there is an influence of prospective bride and groom counseling on mother's compliance in carrying out standard pregnancy checks at Banggae 1 Majene community Health centers.
STUDY OF CLINICAL PROFILE OF INTRAUTERINE GROWTH RESTRICTION BABIES ADMITTED IN NEONATAL INTENSIVE CARE UNIT AT A TERTIARY CARE HOSPITAL- A DESCRIPTIVE CROSS-SECTIONAL STUDY
Authors: Khade Samta , Shah Bhavesh
Published: September 2023

Background: IUGR is the failure of the fetus to reach its growth potential. Fetal growth is regulated at multiple levels. Besides maternal disorder,
fetal structural and chromosomal anomalies are the added factors. The morbidities associated with IUGR could have long term implications in
adult life which predisposes in a development of a number of chronic diseases.Material: It is a cross-sectional study conducted at Neonatal
Intensive Care Unit of a Tertiary Care Hospital. Database of all admissions in NICU during the above period were reviewed. Case records of all
babies admitted were analyzed. Among all the (IUGR) babies admitted in NICU during the study period, Total 120 neonates, who satised the
Inclusion criteria were selected by systematic random sampling. The risk factors, clinical status and immediate outcome were obtained from the
case records. An informed consent was take before analyzing the case records. Results: Among the total study population of 120 IUGR babies, 67
(55.83%) are males and 53 (44.17%) are females. Among the 120-study population 82 (68.3%) babies were classied as asymmetrical IUGR and
38 (31.7%) babies were classied as symmetrical IUGR as per Ponderal Index. Hypoglycemia 73(60.83%), Hypocalcaemia 36(30.00%), Birth
Asphyxia 34 (28.33%), and Neonatal Sepsis 30(25.00) are the commonest complication. Conclusion: Hypoglycemia, hypocalcaemia and
hypothermia are the common treatable complications in this study which can be easily identied and treated. So, in IUGR babies it is important to
anticipate these conditions and treat appropriately to prevent further morbidity and mortality
Analytical solution of Maxwell's equations for arbitrarily moving point charges and its application for ultra-fast, high-quality simulation of electromagnetic fields
Authors: Kühn Steffen
Published: September 2023

Maxwell's equations from the 19th century and the almost equally old Lorentz force equation provide the theoretical basis of all of electrical engineering and consequently the foundation for the majority of all modern technologies. For point charges, this system of partial differential equations reduces to the Weber-Maxwell wave equation. In this article, it is shown that this wave equation can be solved analytically for arbitrarily moving point charges, including accelerated charges, and that it is possible to present an analytical solution in the style of Coulomb's law. This finding demonstrates that classical electrodynamics, with all of its numerous wave phenomena, can also be represented without differential equations. This is surprising and unexpected. Moreover, this work enables the development of a novel class of electromagnetic field solvers that are highly superior in terms of speed and quality to existing solvers based on finite-difference time-domain methods, the method of moments, or finite element methods. In the future, this solution will make it possible to simulate any electromagnetic task in interactive form at previously unattainable quality, even on low-performance computers.

Áreas protegidas são estratégias eficazes de preservação e conservação do patrimônio natural, desde que geridas de forma efetiva. A gestão participativa de uma unidade de conservação pode ser entendida como a administração equilibrada dos componentes técnicos e operacionais, o que compreende os recursos humanos, materiais e financeiros, além do levantamento e aproveitamento dos conhecimentos e habilidades das comunidades locais, no desenvolvimento de planos e estratégias, que visem o atingimento dos objetivos de conservação da área. Avaliar a gestão participativa de uma unidade de conservação é analisar sua capacidade de executar as ações relacionadas com seus objetivos de conservação e preservação. O presente trabalho teve como objetivo avaliar a gestão do Parque Estadual do Monge, utilizando como ferramenta uma metodologia elaborada para analisar a efetividade da gestão participativa, considerando os principais instrumentos de participação social previstos na Lei do SNUC, consulta pública, plano de manejo e conselho gestor. Os resultados mostraram que o parque atingiu um percentual de 50,3% de efetividade de gestão participativa, o que indica que a unidade de conservação (UC) possui alguns recursos e meios para a gestão efetiva, porém faltam alguns elementos para se atingir o mínimo necessário, como por exemplo recursos financeiros e humanos, o que pode acarretar o descumprimento dos objetivos de conservação da área, não garantindo sua preservação a longo prazo.

Published: September 2023

Artykuł jest próbą zrekonstruowania powstania oraz analizą działalności i strategii programowej – założonego w 2008 r. przy Stowarzyszeniu Filmowców Polskich – Studia Munka. Podstawowe pytanie badawcze, jakie stawia sobie autor tekstu, dotyczy dialogu produkcyjnego między pokoleniami, których przedstawiciele byli inicjatorami powstania studiów mających produkować filmy młodych reżyserów. A zatem: jak idea Studia Munka koresponduje z – zasłużonymi dla historii polskiego kina – instytucjami filmowymi, takimi jak zespoły filmowe, Studio Filmowe im. Karola Irzykowskiego czy Filmowe Studio Młodych im. Andrzeja Munka, działające na przełomie lat 70. i 80. w strukturach TVP?

Published: September 2023

The effects of the minimum wage on income inequality in households were assessed in the article, by using the differences-in-differences method. The authors claim that since the minimum wage in Azerbaijan is much lower than the average wage, as well as because the number of waged (and salaried) employees has a small share in the total employment, the impact of the minimum wage on the total income of households is not felt. However, such an effect can be observed in the income inequality of low-income families. The authors suggest that the minimum wage should be closer to the average wage and the level of self-employment in the country should decrease. This can lead to a reduction in income inequality between households.
