Published: January 2024

In this paper, a 100CMM regenerative thermal oxidizer (RTO) system based on a high heating device for low-emission combustion is implemented at a volatile organic compound (VOCs) gas generation workplace. Existing RTO has a structure that repeats the inflow and discharge of VOCs gas into a cylindrical drum-type rotating disk and has excellent energy efficiency with a heat recovery rate of 95% or more. However, when used for a long time, there is a problem that rotation stops or explodes due to the discharge of pollutants due to dust and thermal expansion due to high temperature of 800℃. To overcome this, a RTO based on a high heating device was developed to reduce low-emission combustion emissions and energy use. Through 177 hours of demonstration time, the oxidation efficiency of VOCs was 97.87%; the waste heat recovery rate was reduced by 95.78%, the fuel consumption was reduced by 21.95%, and the nitrogen oxide concentration was 3.9 ppm

Significance. Improvements in health indicators and life quality of the population largely depend upon the organization of primary health care. Despite health care reforming carried out by the state, many problems related to the organization of primary care delivery remain unresolved. In order to obtain an objective assessment of the accessibility of medical care provided in outpatient setting, it is advisable to perform a statistical analysis of the indicators of the workload of doctors, staffing and the number of the population served. The purpose of the study was to assess the accessibility of primary health care to the adult population of the Saratov region, to analyze staffing with medical personnel at the regional level and to identify problematic issues. Material and methods. The study was conducted on the basis of three randomly selected polyclinics of the city of Saratov and the Engels district of the Saratov region in 2020 and 2021, the average number of the attached population in which equaled to 47517.3 ± 16109.8. The necessary data for calculating statistical indicators were obtained from the official medical reports of polyclinics (Form#30), the availability of slips was assessed using the BARS medical information system. The results were processed using the Microsoft Excel 97 software package. Results. In all polyclinics, there is an incomplete staffing with primary care physicians (district doctors), which may be due to a large shortage of district doctors in the Volga Federal District and the lowest level of wages in comparison with other regions. Most of the primary health care is provided by narrow specialists, resulting in excessive specialization of outpatient care, insufficient attention to the training of district doctors and their acute shortage. The increased workload of doctors leads to a shorter time of the visit, which may result in collecting incomplete history and implementing incomplete examination because of the limited time, contributing to untimely detection of a number of diseases in early stages, leading to higher morbidity, mortality and disability. Conclusion. Compliance with the basic principles of medical care delivery by polyclinics # 1,2 and 3 can be assessed as satisfactory, since despite the heavy workload, polyclinics perform their work with dignity, most performance indicators comply with the accepted norms and state standards.

La autorreconstrucción narrativa y gráfica en Los Juncos de Sandra Uve
Authors: Mohring Agatha
Published: January 2024

Este artículo presenta la novela gráfica autobiográfica española Los Juncos (2006) de Sandra Uve, argumentando a favor de su dimensión pionera. Analiza cómo Sandra Uve compone una autobiografía femenina, íntima e intermedial a través del estudio de los procesos de autorreconstrucción narrativa y gráfica. Trata de mostrar que dichas estrategias se basan en la búsqueda de una forma de espontaneidad y de sinceridad autobiográfica. Y asimismo intenta probar que la autora juega con comentarios y técnicas de distanciamiento que introducen una dimensión reflexiva en la obra. Cuestiona, por fin, las fronteras borrosas de la introspección. El artículo adopta una perspectiva intermedial al precisar las influencias de otros medios en la novela gráfica y en la recomposición de la autobiografía, y presta especial atención a la plasmación gráfica y narrativa de lo íntimo, demostrando que la dinámica autobiográfica de Los Juncos toma la forma de una autorreconstrucción narrativa y gráfica que oscila entre la ilusión de sinceridad, el autocomentario y la autorrepresentación distanciada.

Hypokalemic (Induced) Periodic Paralysis is a rare group of disorders that can cause sudden onset of flaccid paralysis. Here we present a case of 41 year old female who presented to the ED complaining of severe flaccid paralysis in both lower & upper limbs since morning. Initially, she was treated as a stroke alert patient and had head scans which showed no acute pathologic changes. Laboratory evaluation revealed a markedly low potassium level. The patient's paralysis resolved after potassium correction and she was discharged with no neurologic deficits. Although rare, Periodic Paralysis must be differentiated from other causes of weakness and paralysis so that the proper treatment can be initiated quickly.

Guillain-Barre Syndrome (GBS) usually present as1 symmetrical ascending muscle weakness associated with areflexia and flaccidity with or without sensory symptoms. However,2 in some patients it may present atypically and one of the rare variant is Pharyngeal-cervical-brachial variant, usually presented as muscle weakness extending from cervical area to the upper extremities often affected with proximal muscle groups. A 20-year-old male presented in ER with complaints of weakness over bilateral upper limb, dysphagia and difficulty in speaking followed by quadriparesis and breathing difficulty. Diagnosis of PCB variant was made by CSF and nerve conduction study and all other possible differentials were excluded.The patient improved by administration of iv immunoglobulin and other supportive measures. Physicians should think about PCB variant of GBS, whenever a patient presenting with symmetrical upper limb weakness and bulbar palsy.

Background and Aim: Several adjuvants have been utilized to enhance the standard of analgesia over the time of post-surgery. We have undertaken this study to evaluate and compare the efficacies of clonidine and dexmedetomidine as an adjuvant to intrathecal hyperbaric 0.5% bupivacaine in patients scheduled for elective lower limb surgeries. Material and Methods: The present study is blinded randomized case control done in the department of the Emergency Medicine in the medical college and associated hospital. All patients undergoing elective lower limb surgery were included for the study. After obtaining the consent letter signed from the patients; total of 180 patients were included in the study. Patients were divided into 3 groups: Group A (control group): received 15mg of 0.5% hyperbaric bupivacaine with 0.5 ml normal saline. Group B (clonidine group): received 15mg of 0.5% hyperbaric bupivacaine with 50µg clonidine. Group C (dexmedetomidine group): received 15mg of 0.5% hyperbaricbupivacaine with 5µg dexmedetomidine. Various parameters were examined were: Onset of sensory blockade and motor blockade, Maximum level of sensory blockade and time taken for the same, Maximum level of motor blockade and time taken for the same. Results: There is no clinical significance between group B and group C regarding mean time taken for onset of sensory blockade. The mean duration of analgesia is 194 ± 26.98 mins in group A (controlgroup), 346.37 ± 32.16 mins in group B (clonidine group) 373.37 ± 38.17 mins in group C (dexmedetomidine group). There is a statistically highly significant difference between group A and group B. Conclusion: The supplementation of bupivacaine with dexmedetomidine 5 μg or clonidine 50 μgin spinal anaesthesia produces significant shorter onset of motor and sensory block with longer duration of sensory and motor block when compared to bupivacaine alone.

Background: Emergency Department (ED) re-attendances are one of the clinical quality indicators to measure the quality of care delivered in the UK. There isn’t much information on ED re-attendance rates and reasons responsible for it during the COVID-19 pandemic. We aim to establish the ED re-attendance rate during the COVID-19 pandemic. Methods: Data for this single centre study was compiled from Symphony, the department’s electronic patient records. We chose the month of April 2020 for this study and subsequently followed up to 28 days for re-attendances. Only patients aged 18 years and older, presenting with COVID-19 symptoms who were discharged from ED were included (n=310). We also studied the hospital admission and mortality rates among the patients who had re-attended. Results: Of the 310, 65 (21%) patients re-attended the ED more than once within 28 days and 27.6% of them belonged to the 41-50 age group. 30 (46.1%) patients were males and 35 (53.8%) were females. The majority (44.6%) of them were of white ethnicity. Among the re-attendees, most of them re-attended only once and within 7 days. Most of the re-attended patients were discharged and only 21 (32.3%) patients had a hospital admission. Of the admitted patients, 6 (28.5%) died in the hospital. Of the patients who died, 5 had tested positive for COVID-19. Conclusions: ED re-attendances were significantly high during the COVID-19 pandemic compared to the national average from previous years.

Superficial vein thrombosis receives little medical attention, however it is not an uncommonly encountered presentation. While previously thought to be a completely benign entity, more recent studies have demonstrated that it may be associated with concomitant deep vein thrombosis and thromboembolic complications.1 Additionally, superficial vein thrombosis is not always self-limiting, and can be prone to tenacity and recurrence, causing significant incapacitation and impairment of daily functional activities, especially when involving the upper extremities. We present the case of a 31-year-old woman who developed extensive superficial vein thrombosis of the non-dominant upper extremity following a brief period of peripheral intravenous cannulation. Our reasons for highlighting this case are: 1. This presentation is usually undermined, and the thromboembolic complications associated with it are not recognized as a sequelae of this entity. 2. To create awareness about current treatment guidelines in superficial vein thrombosis.

Interpretable Lost Circulation Analysis: Labeled, Identified, and Analyzed Lost Circulation in Drilling Operations
Authors: Feng Yongcun , Yang Heng , Li Xiaorong , Zhang Shuai , Hu Han , Wang Jinshu
Published: January 2024

Lost circulation (LC) is a serious problem in drilling operations, as it increases nonproductive time and costs. It can occur due to various complex factors, such as geological parameters, drilling fluid properties, and operational drilling parameters, either individually or in combination. Therefore, studying the types, influencing factors, and causes of LC is crucial for effectively improving prevention and plugging techniques. Currently, the expert diagnosis of LC types relies heavily on the experience and judgment of experts, which may lead to inconsistencies and biases. Additionally, difficulties in obtaining data or missing important data can affect the efficiency and timeliness of diagnosis. Traditional physical modeling methods struggle to analyze complex factor correlations, and conventional machine learning techniques have limited interpretability. In this paper, we propose an interpretable lost circulation analysis (ILCA) framework that provides a new method for analyzing LC. First, we use Gaussian mixture model (GMM) clustering to analyze the LC characteristics of regional case data, efficiently and accurately labeling 296 LC events. Second, we establish the relationship between geological features, drilling fluid properties, operational drilling parameters, and LC types using the XGBoost algorithm. This enables timely identification of LC types during drilling operations using real-time data, with a precision greater than 85%. Finally, we use interpretable machine learning techniques to conduct a comprehensive quantitative analysis of influencing factors based on the established XGBoost model, providing a clear explanation for the identification model. This enables drilling engineers to gain deeper insights into the factors influencing LC events. In summary, the proposed ILCA framework is capable of efficiently labeling LC types based on regional case data, identifying LC types in a timely manner using real-time data, and conducting quantitative analysis of the factors and causes of LC. This approach addresses the limitations of traditional methods and offers valuable insights for drilling engineers.

Published: January 2024

Objective: This study examined whether self-coldness moderates the relationship between negative and positive evaluation on social anxiety. Considering the characteristics of the subtypes of social anxiety disorder, both social interaction anxiety and performance anxiety were included.
Methods: Two hundred and eighty-four students in a university located in Gyeonggi-do were asked to complete the measures assessing the fear of negative and positive evaluation, social interaction anxiety, performance anxiety, and self-coldness. After conducting descriptive statistics and correlation analysis, hierarchical multiple regression analysis was performed.
Results: The results showed that self-coldness moderated the effects of the fear of positive evaluation on social interaction anxiety and performance anxiety. Self-coldness also moderated the effects of the fear of positive evaluation on performance anxiety. However, there was no moderating effect on the effect of the fear of positive evaluation on social interaction anxiety.
Conclusions: In intervening in social anxiety disorder, it may be useful to focus on both the fear of negative and positive evaluation and alleviate self-coldness. In addition, psychotherapeutic intervention should consider the subtypes of social anxiety disorder.

Background
We profiled circulating plasma metabolites to identify systemic biochemical changes in clinical and biomarker-assisted diagnosis of Alzheimer’s disease (AD).
Methods
We used an untargeted approach with liquid chromatography coupled to high-resolution mass spectrometry to measure small molecule plasma metabolites from 150 clinically diagnosed AD patients and 567 age-matched healthy elderly of Caribbean Hispanic ancestry. Plasma biomarkers of AD were measured including P-tau181, Aβ40, Aβ42, total-tau, neurofilament light chain (NfL) and glial fibrillary acidic protein (GFAP). Association of individual and co-abundant modules of metabolites were tested with clinical diagnosis of AD, as well as biologically-defined AD pathological process based on P-tau181 and other biomarker levels.
Results
Over 6000 metabolomic features were measured with high accuracy. First principal component (PC) of lysophosphatidylcholines (lysoPC) that bind to or interact with docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA) and arachidonic acid (AHA) was associated with decreased risk of AD (OR = 0.91 [0.89–0.96], p = 2e-04). Association was restricted to individuals without an APOE ε4 allele (OR = 0.89 [0.84–0.94], p = 8.7e-05). Among individuals carrying at least one APOE ε4 allele, PC4 of lysoPCs moderately increased risk of AD (OR = 1.37 [1.16–1.6], p = 1e-04). Essential amino acids including tyrosine metabolism pathways were enriched among metabolites associated with P-tau181 levels and heparan and keratan sulfate degradation pathways were associated with Aβ42/Aβ40 ratio.
Conclusions
Unbiased metabolic profiling can identify critical metabolites and pathways associated with β-amyloid and phosphotau pathology. We also observed an APOE-ε4 dependent association of lysoPCs with AD and biologically based diagnostic criteria may aid in the identification of unique pathogenic mechanisms.

As a result, healthcare institutions have been searching for frameworks which can help them in difficult circumstance to improve their quality by increasing their dynamic capabilities and organisational competencies. This research set out to identify such a framework. On the basis of a review of the extant literature the HPO Framework was chosen and subsequently applied at three Dutch nursing home care institutions. In a period of three years the HPO Diagnosis was performed at the three institutions. This yielded information on their status on the way to high performance and attention points which they needed to address to help them further along their journey. Based on an analysis of the transformation process, the experiences and lessons learned from each institution were identified and summarised. All institutions had made progress and achieved better organisational results because of the application of the HPO Framework.

Our proposed RDHNet network model is based on semantic segmentation of nighttime scenes and consists of three modules and a multi-head decoder. The three modules - Histogram, MSRCR(Multi-scale Retinex with color restoration), and N-EX(No exposure) - aim to enhance the robustness of RDHNet for image segmentation under different lighting conditions. The histogram module prevents over optimization of well lit images, while the MSRCR module enhances images with insufficient lighting, improving object recognition and facilitating segmentation. The N-EX module uses a dark channel prior method to remove excess light covering the surface of an object. Extensive experiments have shown that the three modules are suitable for different network models and can be inserted and used at will. They significantly improve the model’s segmentation ability for nighttime images while also having good generalization ability. When added to the multi-head decoder network, MIoU has increased by 6.2% on the nighttime dataset Rebecca and 1.5% on the daytime dataset CamVid.

Speed and stability play crucial roles in the performance of high-speed crafts. In the present paper, a two-stepped model is tested in towing tank and compared with stepless and wedge-mounted models, which have previously been tested by the authors. This study is conducted to compare the stability and performance of the mentioned models in the displacement, semi-planing, and planing regimes. The length and width of these models are 2.64 meters and 0.55 meters, respectively. The measured parameters include trim, rise-up, and resistance. The whisker sprays of the models are also depicted at different speeds. the performance of stepped boats is not suitable prior to the planing regime. But wedged model can perform well in this area. One of the features of this type of model is having a chine. So far, no comparison has been made between the chined models. Further, the whisker spray edge approaches to the keel line by increasing speed in all considered models. These tests are conducted in three series at speeds of 2,4,6 and 8 m/s within the mentioned motion regimes. Based on the experimental findings, it is observed that tested models are stable in displacement and semi-displacement regimes. The bare hull which has no transverse step or wedge, is longitudinally unstable in planning regime. However, the vessels with two transverse steps exhibit longitudinal stability and have less drag than the bare-hull model in all motion regimes. On the other hand, the trim and rise-up in stepped as well as wedged vessel are less than those in the bare-hull model in all motion regimes. Meanwhile, the drag of the two-step model at high speeds is determined to be less than the other two models. Ultimately, using the Taguchi design method, different wedge-mounted and two-stepped vessels are selected to conduct numerical studies. These simulations are done via STAR-CCM + commercial code. The calculated results show that at speeds higher than 8 m/s, the resistance could be reduced by optimizing the step location. As the first step gets farther from the stern, the resistance of the vessel reduces. However, increasing the distance between the second step and the stern leads to a drag penalty for the vessel.

Intestinal microbiota plays a crucial role in the health and diseases. However, very little is known about the impact of sampling methods on assessing intestinal microbiota. In this study, we investigated and compared the influence of sampling methods on the intestinal microbial community composition and function using approximately 300 GB of metagenomic sequencing data from 91 samples representing different digestive tract segment with swab and fecal samples of monogastric (donkeys) and polygastric (cows) animals. We assembled 4,004,115 (cow) and 2,938,653 (donkey) contigs, and got 9,060,744 genes showing the swab sampling revealed a higher abundance of Bacteroidetes, while the fecal sampling showed a relatively higher proportion of Firmicutes. In addition, we observed the significant variations in the microbial composition between different digestive tract segments in both animals. Finally, our study identified several key species and pathways in different of sampling methods and provided evidence that sampling methods can influence their co-abundance relationship, which expands our current knowledge using appropriate sampling methods to accurately characterize the gut microbiota composition and function.

Fe3GaTe2 is a promising ferromagnet for above-room temperature spintronics. Yet, vital magnetic and electrical characteristics remain elusive, including spin interaction, spin universality class, and intrinsic anomalous Hall conductivity. We conducted a combined critical exponent analysis, angleresolved photoemission spectroscopy (ARPES), wide-field nitrogen-vacancy center magnetometry, and DFT calculations. Results show that there exist multiple magnetic phases in Fe3GaTe2: paramagnetic to ferromagnetic transition at ∼ 344 K, chiral helimagnetic kink, and spin reorientation transition at ∼ 80 K. Critical exponents (β=0.3706, γ=1.326, and δ=4.72), confirm the coexistence of itinerant and localized spin electrons in Fe3GaTe2, intimately governed by two-dimensional spin interactions resulting from highly anisotropic exchange coupling strengths, remaining robust across thickness, even to few layers. The wide-field nitrogen-vacancy (NV) centre magnetometry technique confirms the existence of room temperature H || c ferromagnetism in the thin sheets (17 nm ) of Fe3GaTe2. The observed high anomalous Hall conductivity is found to be intrinsic, primarily from the Berry curvature. Meanwhile, the DFT band dispersions reveal a partially half-metallic behavior in Fe3GaTe2 and replicate well the ARPES spectrum. Our findings enhance comprehension of 2D spin interactions in 3D Van Der Waal materials and highlight their robustness when thinned to the 2D limit.

Background. Intellectual and developmental disabilities (IDDs) are associated with both cognitive challenges and difficulties in conceptual, social, and practical areas of living (DSM–5). Individuals with IDD often present with an intellectual disability in addition to a developmental disability such as autism or Down syndrome. Those with IDD may present with deficits in intellectual functioning as well as adaptive functioning that interfere with independence and living skills. The present study sought to examine associations of longitudinal developmental change in domains of cognition (NIH Toolbox Cognition Battery, NIHTB-CB) and adaptive behavior domains (Vineland Adaptive Behavior Scales-3; VABS-3) including Socialization, Communication, and Daily Living Skills (DLS) over a two-year period.
Methods. Eligible participants for this multisite longitudinal study included those who were between 6 and 26 years at Visit 1, and who had a diagnosis of, or suspected intellectual disability (ID), including borderline ID. Three groups were recruited, including those with fragile X syndrome, Down syndrome, and other/idiopathic intellectual disability. In order to examine the association of developmental change between cognitive and adaptive behavior domains, bivariate latent change score (BLCS) models were fit to compare change in the three cognitive domains measured by the NIHTB-CB (Fluid, Crystallized, Composite) and the three adaptive behavior domains measured by the VABS-3 (Communication, DLS, and Socialization).
Results. Over a two-year period, change in cognition (both Crystalized and Composite) was significantly and positively associated with change in daily living skills. Also, baseline cognition level predicted growth in adaptive behavior, however baseline adaptive behavior did not predict growth in cognition in any model.
Conclusions. The present study demonstrated that developmental improvements in cognition and adaptive behavior are associated in children and young adults with IDD, indicating the potential for cross-domain effects of intervention. Notably, improvements in Daily Living Skills on the VABS-3 emerged as a primary area of adaptive behavior that positively related to improvements in cognition. This work provides evidence for the clinical, “real life” meaningfulness of the NIHTB-CB in IDD, and important empirical support for the NIHTB-CB as a fit-for-purpose performance-based outcome measure for this population.

Plant trait variation drives plant resource economic strategies, referred to plant economic spectrum (PES). The variation within and across species have afterlife effects on carbon and nutrient cycling through the alteration of litter decomposability. However, PES focus on leaves may not reflect a whole-plant economic spectrum of strategies. Here, we assessed the patterns and predictors of flower and leaf litter decomposition at the intra- (i.e. flowers and leaves of the same species) and inter-specific (i.e. flowers and leaves from different species) levels for 29 species evaluating nine litter traits. Our results indicate flower litter as a labile organic matter due its higher decomposition rate, leaching, water-holding capacity, N, P, and K concentrations. Leaf litter had higher density, Ca, Mg, and Na concentration. The average relative differences for decomposition rate and functional traits between flower and leaf litter did not differ at both intra- and inter-specific levels. The predictors of decomposition were similar, with leaching, P, Ca, Mg, and Na predicting both flower and leaf litter decomposition. While water-holding capacity predicted only flower litter, and density, N, and K predicted leaf litter. The observed differences for decomposition rate and functional traits between flower and leaf litter indicate that the afterlife effects differ among these plant organs and leverage the role of flower litter and its secondary consequences to nutrient and carbon cycling on ecosystems.
