Detection of defects during laser-powder interaction by acoustic emission sensors and signal characteristics

Acoustic Emission (AE) sensing is an in-situ real-time nondestructive monitoring method proposed for Additive Manufacturing (AM) to detect defects such as cracks. Previous AE research in AM mainly focused on developing algorithms to automatically detect the defects from AE signals without understanding the physical mechanisms or the signal characteristics that could be used as identifiers. We study AE signals during a laser spot welding on a powder bed to clearly distinguish between different physical mechanisms using their signal characteristics. We identified specific signals associated with 1) tensile cracks from cooling, 2) a powder effect on the substrate, and 3) sudden thermal expansion of the substrate. We used the spectral ratio between high frequency (70–150 kHz) and low frequency (10–40 kHz) spectral amplitudes in the frequency domain to classify and differentiate the source types. We found that porosity due to insufficient energy density did not produce detectable AE signals. Using a ball drop calibration technique, we used AE signals to estimate the absolute sizes of the tensile cracks. Crack sizes ranged from 40 μm to 1 mm and were in general agreement with scanning electron microscope images of the fractures. We performed a line scanning test and successfully validated its potential for the application. Our findings provide a basic understanding of AE signal characteristics in AM, as well as the practical parameters used to separate the signal types.

Micro Machining of a Si3N4/SiO2/Ti/Pt Hotplate and Its IR Emissivity Properties

This paper presents the fabrication processes for a Si3N4/SiO2/Ti/Pt membrane based micro hotplate (MHP) using photolithography (PL) micro-machining techniques. The properties of the MHP filament are investigated and overall performance characteristics with regard to infrared (IR) radiation emissivity, resistance, breakdown voltage, and temperature of the fabricated Si3N4/SiO2/Ti/Pt micro heater. During characterization, the results show the device breakdown voltage of 24.24 V corresponding to the optimum operation temperature of ~ 1730.30 K. The device also showed an emissivity value of 5.2% with ~ 7% efficiency of transforming electrical power to IR thermal radiation power. The relationship between temperature and resistance, behaviour of fourth power of temperature and thermal response time constant of IR radiation obtained from direct experimental measurements, analytical calculations and extrapolations are shown to provide practical parameters that are needed for applications of MHP in IR radiation sources.

Collaborative Inversion of Soil Water Content in Alpine Meadow Area Based on Multitemporal Polarimetric SAR and Optical Remote Sensing Data

Soil water content is a critical environmental parameter in research and practice, though various technological and contextual constraints limit its estimation in arid areas with vegetation cover. This study combined the multitemporal remote sensing data of Sentinel-1 and Landsat 8 to conduct an inversion study on surface soil water content under low vegetation cover in Nagqu, central Tibetan Plateau. Four vegetation indices (NDVI, ARVI, EVI, and RVI) were extracted from optical remote sensing data. A water cloud model was used to eliminate the influence of the vegetation layer on the backscattering coefficient associated with vegetation cover, and a predictive model suitable for the Nagqu area was constructed. The water cloud model effectively incorporated a vegetation index instead of vegetation water content. We found that VV polarization was more suitable for soil water content inversion than VH polarization. Among the four vegetation indices, the soil water content inversion model constructed with RVI under VV polarization had the best fit (R2 = 0.8212; RMSE = 6.30). The second-best fit was observed for vegetation water content-NDVI (R2 = 0.8201). The soil water content inversion models all had an R2 > 0.6, regardless of the vegetation index used, though the RVI had the best fitting effect, indicating that this vegetation index is highly applicable in the water cloud model, as a substitute for vegetation water content, and is expected to perform well in similar study sites.

Removal of nitric oxide in bioreactors: a review on the pathways, governing factors and mathematical modelling.

The constant surge in nitric oxide in the atmosphere results in severe environmental degradation, negatively impacting human health and ecosystems, and is presently a global concern. Widely used physicochemical technologies for nitric oxide (NO) removal comes with high installation and operational costs and the production of secondary pollutants. Thus, biological treatment has been emphasized over the last two decades, but the poor solubility of NO in water makes it a challenging issue. The present article reviews the various technical aspects of biological treatment of nitric oxide, including the removal pathways and reactor configurations involved in the process. The most widely used technologies in this regard are chemical adsorption processes followed by biological reactors like biofilters, biotrickling filters and membrane bioreactors that enhance NO solubility and offer the flexibility and scope of further improvement in process design. The effect of various experimental and operational parameters on NO removal, including pH, carbon source, gas flow rate, gas residence time and presence of inhibitory components in the flue gas, is also discussed along with the developed mathematical models for predicting NO removal in a biological treatment system. There is an extensive scope of investigation regarding the development of an economical system to remove NO, and an exhaustive model that would optimize the process considering maximum practical parameters encountered during such operation. A detailed discussion made in this article gives a proper insight into all these areas.

Assessing Student Nurses Perceptions of Practical Education at the Nursing Institute in Kenitra Morocco: A Comparative Study

Practical education is one of the main components of nurse training. Assessing student nurses enables us to detect their perceptions of the style of practical education and its impact on practical learning. This diagnosis informs improvements in student nurses' practical learning. Student nurses' perceptions of the practical teaching method are essential as beneficiaries of this training and as partners in the training program. The aim of our study is to describe and analyze the views of student nurses on the parameters of practical education at the Kenitra nursing institute in Morocco. This study was carried out in accordance with the recommendations of Knox and Mogan's (1985) theoretical model of practical nursing education. The results detected reveal that the parameter of teaching ability is ranked first with a high rating (5,74±1.81), secondly, we find the parameter of nursing competence followed by interpersonal relationship and personality, the parameter of evaluation is underestimated by students with a very low rating (5.35±1.88). The Mann-Whitney test showed that there was a difference in perception of the practical teaching parameters between the two groups of students, but this was statistically insignificant, with p-values greater than 0.05. In order to achieve continuous improvement in the education of student nurses, further in-depth studies must be carried out to complete the diagnosis and plan actions for improvement, with the aim of producing qualified and competent nurses able to deal with the realities of the health system.

Pain Management in the Community: The Empowerment of District on Collaboration of Complementary Nursing at Bukittinggi, West Sumatera

Pain is a global health issue. It is estimated that every year 20% of the world's population experiences pain and half of this is chronic pain. In Indonesia there has been no large-scale research discussing the prevalence and quality of all types of pain. Indonesia also does not yet have practical parameters for assessing pain, patient comfort levels, and the effect of pain on the quality of life of the Indonesian people. This Community Service (PKM) seeks to provide training and raise information about pain treatment in one of the districts of Bukittinggi, West Sumatera, through socializing and outreach to the community. The strategy employed in this PKM includes counseling about pain management in the community and how to handle it. This PKM obtained an increase in the knowledge and skill of community members in controlling their pain. According to the findings of monitoring and analyzing PKM activities, the community health service was ready to improve people's pain management strategies. It is believed that this activity will be beneficial in enhancing the knowledge and experience of pain management that may be used in the community health service by individuals and their families, particularly in non-pharmacological approaches as complementary pain management nursing.

Modified swede colposcopic index versus modified reid index in colposcopic screening for premalignant & malignant lesions of the cervix: a cross-sectional analysis

BackgroundCervical cancer cases in India account for one-fourth of the worldwide burden. Colposcopy is used to evaluate the cervix of women with abnormal screening test results. For standardized reporting, various scores were introduced of those, Reid Colposcopic Index (RCI) and Swede score are the most commonly used. Aims and ObjectivesThis study is undertaken to determine the diagnostic efficacy and clinical relevance of the newly introduced MSCI and compare MSCI and Modified Reid Index. Results225 women out of 237 were analyzed. MSCI score 9 perform best for colposcopic diagnosis of CIN 2 or higher lesions. The sensitivity, specificity, PPV, and NPV for threshold score 9 for CIN 2 or higher lesions were 94.92 %, 67.88 %, 51.38 %, and 97.39 % respectively. Modified Reid Index threshold 3 performed best for the detection of CIN 2 or higher lesions with a sensitivity, specificity, PPV, and NPV of 84.75 %, 44.85 %, 35.46 %, and 89.16 % respectively. On comparing the area under the curve (AUC) for MSCI and MRI, we found that the difference between the AUC of MSCI (0.854) and Modified Reid Index (0.657) was significant (P < 0.05). ConclusionMSCI performs better than the modified reid index for the diagnosis of both HGL and LGL or higher. Also, the omission of impractical measurements and inclusion of easier and more practical parameters than the Swede score or Modified Reid Index makes MSCI a simple and effective screening tool

FGL2 as a predictive biomarker for prognosis and immunotherapy in bladder cancer.

Background: Metastasis and immunosuppression result in unfavorable prognosis in bladder cancer (BLCA). FGL1 and FGL2 are two members of the fibrinogen-related proteins family, but their potential effects on BLCA remain elusive. Methods: The expression profile of FGL1 and FGL2 in BLCA was analyzed in multiple databases. Furthermore, the expression of FGL2 was validated in BLCA tissues. The predictive capability of FGL2 was evaluated by Kaplan-Meier analysis, univariate analysis, and multivariate Cox regression. A nomogram model was constructed based on FGL2 expression and clinicopathological parameters for clinical practice. Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Gene Set Enrichment Analyses (GSEA) were performed to investigate enrichment in the biological processes. In addition, the correlation between FGL2 and immunological characteristics in the BLCA tumor microenvironment (TME), including tumor-infiltrating immune cells (TICs), cancer-immunity cycles, immune checkpoint molecules (ICPs), immunophenoscores (IPS), and response to anti-PD-L1 immunotherapy was further analyzed. Results: FGL2 was found to be downregulated in BLCA due to hypermethylation of the FGL2 promoter region, which was associated with an unfavorable prognosis. Moreover, BLCA patients with high FGL2 expression exhibited better response to immunotherapy. Conclusions: Our research revealed that FGL2 was downregulated in BLCA and was negatively correlated with DNA methylation. High FGL2 expression was confirmed as an independent risk for prognosis. Moreover, FGL2 is a promising indicator for the response to immunotherapy in patients with BLCA.

Alterations in some hematological parameters of feline blood samples preserved at different temperatures for a duration of up to 48 hours

Hematological parameters serve as vital diagnostic tools in veterinary medicine, aiding in the identification of various diseases and metabolic conditions in animals. However, their reliability can be influenced by a multitude of factors, including storage conditions and duration. Pre-analytical errors, which account for up to 70% of laboratory diagnostic errors, primarily stem from issues such as sample collection, transportation, and storage. To address this, the European Federation of Clinical Chemistry and Laboratory Medicine-Working Group for the Preanalytical Phase conducted a survey to understand pre-analytical practices among human laboratories. Despite significant interest, diversity in monitoring approaches was noted among European laboratories. The complete blood count (CBC) stands as a frequently requested test by veterinarians, but its accuracy can be affected by pre-analytical variables like storage temperature and delay in analysis. This study aimed to assess the stability of hematological parameters in feline blood samples stored at different temperatures (4°C and 20°C) for up to 48 hours. Ten clinically healthy cats were included in the study, with blood samples collected and analyzed immediately and at various time points over 48 hours. Results showed stability in hemoglobin concentration for 48 hours at both temperatures. However, RBC and PCV values increased significantly after 24 hours at 20°C. MCV, MCH, and MCHC values remained relatively stable over time, with minor fluctuations. Notably, WBC counts declined significantly after 48 hours at 20°C, while no significant changes were observed at 4°C. These findings underscore the importance of prompt analysis and appropriate storage conditions in maintaining the integrity of hematological parameters in veterinary practice. In conclusion, blood samples from cats stored at 4°C remain reliable for up to 48 hours for most hematological parameters, while samples stored at 20°C are suitable for up to 24 hours. These findings provide valuable insights for veterinarians and laboratory professionals, emphasizing the need for standardized pre-analytical practices to ensure accurate diagnostic results in veterinary hematology.

Prognostic value of myocardial deformation parameters for outcome prediction in tetralogy of Fallot

BackgroundThe prognostic value of myocardial deformation parameters in adults with repaired tetralogy of Fallot (rTOF) has not been well-elucidated. We therefore aimed to explore myocardial deformation parameters for outcome prediction in adults with rTOF using cardiovascular magnetic resonance imaging (CMR). MethodsAdults with rTOF and at least moderate pulmonary regurgitation were identified from an institutional prospective CMR registry. Left ventricular (LV) and right ventricular (RV) global strains were recorded in longitudinal (GLS), circumferential (GCS), and radial (GRS) directions. Major adverse cardiovascular events (MACE) were defined as a composite of mortality, resuscitated sudden death, sustained ventricular tachycardia (>30 seconds), or heart failure (hospital admission >24 hours). In patients with pulmonary valve replacement (PVR), pre- and post-PVR CMR studies were analyzed to assess for predictors of complete RV reverse remodeling, defined as indexed RV end-diastolic volume (RVEDVi) <110 mL/m2. Logistic regression models were used to estimate the odds ratio (OR) per unit change in absolute strain value associated with clinical outcomes and receiver operator characteristic curves were constructed with area under the curve (AUC) for select CMR variables. ResultsWe included 307 patients (age 35 ± 13 years, 59% (180/307) male). During 6.1 years (3.3–8.8) of follow-up, PVR was performed in 142 (46%) and MACE occurred in 31 (10%). On univariate analysis, baseline biventricular ejection fraction (EF), mass, and all strain parameters were associated with MACE. After adjustment for LVEF, only LV-GLS remained independently predictive of MACE (OR 0.822 [0.693–0.976] p = 0.025). Receiver operator curves identified an absolute LV-GLS value less than 15 and LVEF less than 51% as thresholds for MACE prediction (AUC 0.759 [0.655–0.840] and 0.720 [0.608–0.810]). After adjusting for baseline RVEDVi, RV-GCS (OR 1.323 [1.094–1.600] p = 0.004), LV-GCS (OR 1.276 [1.029–1.582] p = 0.027) and LV-GRS (OR 1.101 [1.0210–1.200], p = 0.028) were independent predictors of complete remodeling post-PVR remodeling. ConclusionBiventricular strain parameters predict clinical outcomes and post-PVR remodeling in rTOF. Further study will be necessary to establish the role of myocardial deformation parameters in clinical practice.

Evaluation of Difference in Emergency Care Quality by Years of Physician Experience at the Emergency Department.

To evaluate the effect of emergency medicine training credentials and years of medical experience on various clinical parameters in emergency medicine practice. A cross-sectional study was conducted at Juntendo University Nerima Hospital between 1 April 2019 and 31 March 2020. All patients who were transported by ambulance, were examined by emergency physicians, and underwent computed tomography (CT) or magnetic resonance imaging (MRI) in the emergency department were included. For these cases, data on the attending physician's qualification status and experience (specialist, nonspecialist with 1-2 years of experience, or nonspecialist with 3-4 years of experience), clinical parameters, and imaging were collected. The primary outcome was the patient's total length of stay (LOS) in the emergency department. A total of 3,784 patients were included in the study. Patients attended by nonspecialists with 1-2 years of experience had a significantly longer time from arrival to assessment and LOS, especially in mild and severe cases and cases requiring head and abdominal CT imaging. Our findings suggest that for physicians with minimal work experience, mentorship and effective training using triage flow and medical examination protocols may help to reduce LOS in the emergency department.

Ultra-broadband sound absorption in a compact multi-chamber micro-perforated panel absorber with varying depths

This study presents an enhanced multi-chamber micro-perforated panel absorber (MC-MPPA) with varying sub-chamber depths, offering ultra-broadband low-frequency sound absorption. Traditional micro-perforated panel absorbers are constrained by a limited bandwidth, necessitating impossibly small perforations for optimal low-frequency absorption. Our innovative design addresses these constraints with a lightweight, compact panel structure that uses varied chamber depths and unique porosities. Using the two-point impedance method from graph theory, an MC-MPPA was modeled and optimized. Notably, our MC-MPPA test pieces achieved impressive sound absorption coefficients experimentally of over 0.8 in the whole frequency ranges of [397–1000] and [698–1895] Hz. The absorber’s thickness is a mere 47 mm, equivalent to 1/18.2 and 1/10.5 of the sound wavelength at the minimum operational frequency, respectively. Theoretically, with a maximum sub-chamber depth of just 20 mm, average absorption coefficient values of 0.6780 and 0.6483 were observed in [200–3000] and [200–4000] Hz ranges, respectively. Our optimization algorithm permits the definition of practical geometric parameters, promising substantial industrial benefits. The results have been validated theoretically, numerically, and experimentally.

A complete year of urology residency training under COVID-19: impact on education and health.

To evaluate the impact of COVID-19 pandemics on clinical and surgical practice, educational activities, health and lifestyle behavior of Brazilian urology residents after 1 year of socio-economic restrictions. An electronic survey was e-mailed to all postgraduate (PG) students registered by the Brazilian Society of Urology. The survey inclu-ded an assessment of socio-demographic, clinical practice, educational, health-related and behavior parameters. We also evaluated which subareas of urology were predominantly affected. A similar survey was adapted and sent to the directors of all urology residency programs. COVID-19 pandemic has severely impacted the clinical, surgical, and educational activities of urology residents in Brazil. Urology residents reported >50% decrease in multiple surgical modalities. We highlight kidney transplantation surgeries (66.2%), minor surgeries (62.3%), endoscopic surgeries (42.6%) and reconstructive surgeries (38.8%). This could represent a critical skills gap that residents may face beyond the COVID-19 pandemic. Furthermore, PG students faced stressful situations that caused worsening of mental and physical health, such as getting redirected to assistance of COVID-19 patients (66.9%), and high rate of infection by SARS-CoV-2 (58.2%). The COVID-19 pandemic has severely impacted the clinical, surgical, and educational activities of urology residents in Brazil. This could represent a critical skills gap that residents may face beyond the COVID-19 pandemic. PG students faced stressful situations that caused worsening of mental and physical health such as redirection to assistance of COVID-19 patients, concern about their own contamination and of family members.

Diriyah Hospital CT Scan Service’s Readiness for ACR Accreditation: A Gap Analysis

ACR clinical service accreditation Guidelines titled the Practice Parameters and Technical Standards help advance the science of radiology by improving the quality of imaging service to patients. Since the use of computed tomography (CT) has rapidly increased since its introduction in the 1970s, physicians see benefits of using computerized tomography (CT) scanning in their patient care management. It is possible nowadays to perform more examinations on time. However, extending the scope of some examinations, as well as introducing some new techniques occurs sometimes. The ease of acquisition of images results sometimes in unnecessary exposure of patients to radiation, particularly in developed countries. Furthermore, organ doses from CT scanning are considerably larger than those from corresponding conventional X-ray. The CT scan is the most appropriate modality of receive a traumatic patients. The CT scan is also very effective in diagnosis of traumatic cases with high resolution in real time mode and visualization of fine details with or without the use of contrast medium. CT is now a standard diagnostic tool for patient’s pathologies detection, trauma, renal calculi, appendicitis, and heart conditions. The speed, accuracy and availability of CT technology have rapidly raised the volume of CT scans performed in patients, despite the fact that CT scanning delivers a higher radiation dose to the patient than other available procedures.

Atlanto-occipital dislocation-A challenge with respect to making the diagnosis and treatment

The correct diagnosis and treatment of the atlanto-occipital dislocation (AOD) remains amajor challenge. To evaluate the different radiological diagnostic criteria for AOD and discuss potential treatment strategies based on acase with AOD and additional fracture of the atlas. A29-year-old male patient is presented who suffered from AOD with concomitant fracture of the anterior and posterior arches of the atlas with rotational atlantoaxial dislocation following an accident in forestry. The following parameters were evaluated for the diagnosis and assessment of postoperative reduction: Powers ratio, the X‑lines-method, Wackenheim line, basion-dens interval (BDI), basion-axial interval (BAI) and occipital condyle-C1 interval (CCI). Stabilization was performed by occipitocervical spondylodesis from C0 to C2/3. For final reduction it was necessary to reduce the malrotation of the atlas. In the presented case, the revised CCI proved to be asensitive and valid yet practical parameter. Powers' ratio and the BDI were less suited for assessing the diagnosis. The X‑lines-method, Wackenheim line and the BAI did not adequately detect the pathological situation. The AOD is asevere injury requiring immediate correct diagnosis for later adequate treatment results. Among the published parameters, the revised CCI proved to be apractical and valid parameter to detect AOD. For definitive treatment, the operative occipitocervical stabilization is regarded as the method of choice.

ACR-ARS Practice Parameter for Radiation Oncology.

This practice parameter was revised collaboratively by the American College of Radiology (ACR), and the American Radium Society. This practice parameter provides updated reference literature regarding radiation oncology practice and its key personnel. This practice parameter was developed according to the process described under the heading The Process for Developing ACR Practice Parameters and Technical Standards on the ACR website ( https://www.acr.org/Clinical-Resources/Practice-Parameters-and-Technical-Standards ) by the Committee on Practice Parameters-Radiation Oncology of the ACR Commission on Radiation Oncology in collaboration with the American Radium Society. This practice parameter provides a comprehensive update to the reference literature regarding radiation oncology practice in general. The overall roles of the radiation oncologist, the Qualified Medical Physicist, and other specialized personnel involved in the delivery of external-beam radiation therapy are discussed. The use of radiation therapy requires detailed attention to equipment, patient and personnel safety, equipment maintenance and quality assurance, and continuing staff education. Because the practice of radiation oncology occurs in a variety of clinical environments, the judgment of a qualified radiation oncologist should be used to apply these practice parameters to individual practices. Radiation oncologists should follow the guiding principle of limiting radiation exposure to patients and personnel while accomplishing therapeutic goals. This practice parameter can be used as an effective tool to guide radiation oncology practice by successfully incorporating the close interaction and coordination among radiation oncologists, medical physicists, dosimetrists, nurses, and radiation therapists.

The utility of ultraviolet beam in advanced oxidation-reduction processes: a review on the mechanism of processes and possible production free radicals.

Advanced oxidation processes (AOPs) and advanced reduction processes (ARPs) are a set of chemical treatment procedures designed to eliminate organic (sometimes inorganic) contamination in water and wastewater by producing free reactive radicals (FRR). UV irradiation is one of the factors that are effectively used in oxidation-reduction processes. Not only does the UV beam cause the photolysis of contamination, but it also leads to the product of FRR by affecting oxidants-reductant, and the pollutant decomposition occurs by FRR. UV rays produce active radical species indirectly in an advanced redox process by affecting an oxidant (O3, H2O2), persulfate (PS), or reducer (dithionite, sulfite, sulfide, iodide, ferrous). Produced FRR with high redox potential (including oxidized or reduced radicals) causes detoxification and degradation of target contaminants by attacking them. In this review, it was found that ultraviolet radiation is one of the important and practical parameters in redox processes, which can be used to control a wide range of impurities.

ACR-ARS Practice Parameter for Communication: Radiation Oncology.

This practice parameter was revised collaboratively by the American College of Radiology (ACR), and the American Radium Society (ARS). Timely, accurate, and effective communications are critical to quality and safety in contemporary medical practices. Radiation oncology incorporates the science and technology of complex, integrated treatment delivery and the art of providing care to individual patients. Through written physical and/or electronic reports and direct communication, radiation oncologists convey their knowledge and evaluation regarding patient care, clinical workup, and treatment provided to others in the management of the patient. Applicable practice parameters need to be revised periodically regarding medical record documentation for professional and technical components of services delivered. This practice parameter was developed and revised according to the process described under the heading "The Process for Developing ACR Practice Parameters and Technical Standards" on the ACR website ( https://www.acr.org/Clinical-Resources/Practice-Parameters-and-Technical-Standards ) by the Committee on Practice Parameters-Radiation Oncology of the ACR Commission on Radiation Oncology in collaboration with the ARS. Both societies have reviewed and approved the document. This practice parameter addresses radiation oncology communications in general, including (a) medical record, (b) electronic, and (c) doctor-patient communications, as well as specific documentation for radiation oncology reports such as (a) consultation, (b) clinical treatment management notes (including inpatient communication), (c) treatment (completion) summary, and (d) follow-up visits. The radiation oncologist's participation in the multidisciplinary management of patients is reflected in timely, medically appropriate, and informative communication with patients, caregivers, referring physician, and other members of the health care team. The ACR-ARS Practice Parameter for Communication: Radiation Oncology is an educational tool designed to assist practitioners in providing appropriate communication regarding radiation oncology care for patients.
