An Improved Channel Flow Measurement Approach Using Conical Central Baffle Flumes
Authors: Nair P Sujith , Ghare Aniruddha. D. , Kapoor Ankur 
Published: April 2023

Abstract

A simple and inexpensive way of channel discharge measurement is to introduce an axial obstruction in the flow cross- section, thereby creating the critical flow conditions. Such flow measuring devices are referred to as baffle flumes. Literature showed that the critical flow conditions are routinely assumed to occur at the minimum flow cross-section in the flume, however practically the critical section lies slightly on the upstream side. This paper presents an analytical approach to deduce the discharge prediction model on the basis of identification of true location of critical flow section that lies near the vicinity of the least constricted section in the baffle flume. Using the experimental data, a relationship between the ratio of energy to critical depth and the geometrical configuration of the baffle flume having conical shaped obstruction in a trapezoidal channel section, is obtained. Coupled with the expression for critical contracted width, the location of the critical flow section is established. Numerical analysis has also been carried out to ascertain the applicability of the proposed discharge prediction model. The discharge prediction model presented herein for the Conical Central Baffle Flume, is found to provide the discharge with better accuracy (maximum error 2.49%) when compared with the Kapoor et al. (2021) model available in the literature (maximum error 5.24%). An illustrative example to demonstrate use of the proposed methodology, is also appended herein for the benefit of the field hydraulic engineers dealing with flow measurements.

Published: April 2023

Abstract
Background: This investigation provides an updated study measuring the levels of chemical components for the top-selling smokeless tobacco products (SLT) viz. khaini, mishri, pan masala + tobacco, snus, and tobacco-betel nut mixture in the Indian market.
Methods:A total of twelve SLT were collected and analyzed for nitrosamines and polycyclic aromatic hydrocarbons using various standard techniques of gas and liquid chromatography(as GC-MS, GC-TEA, LC-MS/MS)at two different laboratories and compared to previous studies.
Results: Mishri contains a major share of tobacco-specific nitrosaminesas NNN (10 folds where folds refer to a comparison of average) and NNK (25-30 folds) with higher ratio than other SLT. Total polycyclic aromatic hydrocarbons content of mishri quantified to be 702-794 µg/g of SLT which was 7-9 fold higher than snus. On geographical distribution, SLT composition reflects inter and intra-differences. TSNA levels were drastically different between mishri and khaini samples. This extensive variation is attributed to tobacco curing and other manufacturing techniques.
Conclusions: Overall, findings indicate mishri to be most harmful among all SLT whereas snus can be considered as an alternative for better public health.The chemical characterization provides a broader understanding of differences in carcinogenic-potential relating to the concentration-variation between the products. Also, the present study would create a database to ensure the consumer's right to be informed about health-risk from a product and make aware of the need to monitor and regulate the ingredients among all SLT used in the country.

Published: April 2023

Abstract
Hydatidosis is a parasitic infection whose etiological agent is the larva of the cestode Echinococcus granulosus. It is a zoonosis and the human being behaves as an accidental intermediate host in the parasitic cycle. The most frequent clinical presentation is hepatic, followed by pulmonary, with cerebral hydatidosis being extremely rare. Imaging is characteristic, generally dealing with single cystic lesion, usually unilocular and less frequently multilocular, located mainly intraaxially. The primary disease remains extremely rare and its clinical picture is related to the number, size, and location of the lesions. Infection within these cerebral hydatid cysts remains an extremely rare occurrence and only few cases reported previously in the literature. The authors report the nosological review of the clinical, imaging, surgical, and histopathological records of an uncommon primary osteolytic pediatric extradural complicated hydatid cyst in a 5 year-old North African male patient coming from a rural area who presented for progressive onset of a painless left parieto-occipital soft swelling without any neurological disorder with good outcomes after surgery. The authors report this case due the fact that it had not been documented before in the pediatric population and to the success of the specialized treatment.

Published: April 2023

Abstract
With the emergence of energy shortages and ecological deterioration in China, the deployment of distributed photovoltaic (PV) as a renewable energy source in rural areas has been recognized as a potential solution for reducing greenhouse gas emissions. This research aims at at investigating the selection of promotion modes for PV installation enterprises in China by utilizing complex network theory to construct a model. The proposed model analyzes the impact of various factors, including villagers' support rate, the vacillation rate, and PV operation and maintenance costs, within an evolutionary game theory on the selection of promotion modes for enterprises. The findings of this study indicate that the villagers' support rate has the most significant influence on the promotion modes selected by enterprises. Therefore, it is crucial to establish appropriate incentives, increase publicity efforts, and educate the villagers about the benefits of PV installation for themselves and the environment. Additionally, PV installation enterprises must prioritize equipment operation and maintenance to ensure the efficient and stable operation of PV devices, which is critical for achieving the energy conservation, the emission reduction, and stable income. Ultimately, this research provides valuable insights for PV installation enterprises to promote distributed PV in rural areas by adjusting the parameter settings based on the evolution results. By adopting the proposed model, PV installation enterprises can optimize their promotion strategies and enhance their chances of success in the rural market, thereby contributing to the reduction of greenhouse gas emissions and achieving sustainable development goals.

Published: April 2023

Abstract
Purpose
The purpose of this study is to determine if depth of infiltration is the only risk factor that will determine the outcomes in early stage buccal mucosa patients or do the other minor risk factors have an impact too.
Methods
It is a retrospective analysis of 226 patients with early stage buccal mucosa cancer who were treated with curative intent from 2010 to 2020. These patients were grouped in two arms, surgery alone(n=111) and surgery followed by adjuvant radiotherapy( n=115).
Patients were followed up and local and regional recurrences and distant metastasis were recorded.
Results
Our results show that addition of Radiation to the standard surgery arm improves overall survival and disease free survival, though the improvement in overall survival was not statistically significant. This improvement was more pronounced in the depth of infiltration >5mm and in 5mm or less depth of infiltration this benefit was not statistically significant. Other factors like perineural invasion, lymphovascular invasion, tumour size, node positive, margin positive were considered for univariate analysis. Although there was a trend towards improvement of OS and DFS it was not statistically significant as far as these factors are concerned.
Conclusion
The role of adjuvant radiation in early stage cancers of buccal mucosa is a crucial tool with definitive DFS benefit and requires more prospective trials to answer the OS benefit.

Published: April 2023

Abstract
Here, CeO2 was used as the sole oxidant for pyrrole polymerization via in-situ chemical oxidation, and polypyrrole (PPy) was grown on the CeO2 surface to form CeO2-PPy nanocomposites. The morphology of CeO2-PPy nanocomposites was observed using SEM. The electrochemical corrosion behavior of the coatings in 3.5 wt% NaCl solution was investigated through electrochemical impedance spectroscopy (EIS) measurements. After 40 days of immersion, the coating with CeO2-PPy nanocomposite fillers exhibited outstanding anti-corrosion performance, and the |Z|0.01 Hz value exceeded 108 Ω·cm2, which was one order of magnitude higher than of the pure epoxy coating. The enhanced corrosion protection was attributed to the complex passive film produced by the synergistic effect of PPy and cerium(Ⅲ) ions. The results showed that CeO2-PPy nanocomposites can be used as fillers for the corrosion protection of steel substrates.
A Computational Study of Cluster Dynamics in Structural Lubricity: Role of Cluster Rotation
Authors: Oo Wai , Baykara Mehmet , Gao Hongyu 
Published: April 2023

Abstract

We present a computational study of sliding between gold clusters and a highly oriented pyrolytic graphite substrate, a material system that exhibits ultra-low friction due to structural lubricity.By means of molecular dynamics, it is found that clusters may undergo spontaneous rotations during manipulation as a result of elastic instability, leading to attenuated friction due to enhanced interfacial incommensurability.In the case of a free cluster, shear stresses exhibit a non-monotonic dependency on the strength of the tip-cluster interaction, whereby rigid clusters experience nearly constant shear stresses.Finally, it is shown that the suppression of the translational degrees of freedom of a cluster's outermost-layer can partially annihilate out-of-plane phonon vibrations, which leads to a reduction of energy dissipation that is in compliance with Stokesian damping. It is projected that the physical insight attained by the study presented here will result in enhanced control and interpretation of manipulation experiments at structurally lubric contacts.

Abstract

Background:Cerebral infarction may occur in patients with aortic dissection. Some neurologists gave intravenous thrombolysis for cerebral infarction without paying more attention to asymptomatic aortic dissection.Methods/Results:We report the case of a 66-year-old female presenting with unconsciousness who was admitted to our hospital. During intravenous thrombolysis (IVT) with alteplase(rt-PA), the patient died suddenly. One-stop skull and neck CT scan was reviewed during the discussion of the death case, asymptomatic aortic dissection was found.Conclusion:IVT with rt-PA in patient with acute cerebral infarction and asymptomatic aortic dissection may lead to lethal outcomes. Although uncommon, recognition of aortic dissection in patient with acute cerebral infarction is important.
Tartary Buckwheat Protein-derived Peptide AFYRW alleviates H2O2 -induced vascular injury via the PI3K/AKT/NF-κB pathway

Published: April 2023

Abstract

Tartary buckwheat protein-derived peptide (Ala-Phe-Tyr-Arg-Trp, AFYRW) is a natural active peptide that hampers the atherosclerosis process, but the underlying role of AFYRW in angiogenesis remains unknown. Here, we present a system-based study to evaluate the effects of AFYRW on H2O2-induced vascular injury in human umbilical vein endothelial cells (HUVECs). HUVECs were co-incubated with H2O2 for 2 h to the vascular injury model, and AFYRW was added 24 h in advance to investigate the protective mechanism of vascular injury. We identified that AFYRW inhibits oxidative stress, cell migration, cell invasion, and angiogenesis in H2O2-treated HUVECs. In addition, we found H2O2-induced upregulation of phosphoinositide 3-kinase (PI3K), protein kinase B (AKT), phosphorylation of nuclear factor-κB (NF-κB) p65 and nuclear translocation of NF-κB decreased by AFYRW. Taken together, AFYRW attenuated H2O2-induced vascular injury through the PI3K/AKT/NF-κB pathway. Thereby, AFYRW may serve as a therapeutic option for vascular injury.
Mixed Adeno-Neuroendocrine Carcinoma of the Appendix Masquerading as Ovarian Cancer: Report of a Case
Authors: Zhang He-wei , He Dan , Zhou Xiao-cong , Jiang Yi 
Published: April 2023

Abstract

Background:We report a rare case of a 52-year-old woman with an initial diagnosis of mucinous adenocarcinoma of the ovary and a final finding of metastatic mixed gonadal neuroendocrine carcinoma of the appendix.Case presentation:A 52-year-old Chinese woman was found to have a mass in the right adnexal region during a physical examination. She underwent a first exploratory laparotomy and had her right adnexa and part of her left ovary removed. Eighteen months later, the left adnexal mass recurred and she underwent a repeat exploratory laparotomy and total hysterectomy, left adnexa, greater omentum, appendectomy and pelvic lymph node dissection.Conclusions: Mixed adeno-neuroendocrine carcinoma of appendix is a rare condition. Often, postoperative pathology is required for diagnosis. The case reported here demonstrates that mixed glandular neuroendocrine carcinoma of the appendix can take the form of ovarian cancer, which can be misdiagnosed, and should therefore be differentiated from mixed adeno-neuroendocrine carcinoma of the appendix by gynaecologists when they encounter cases of ovarian cancer.

Published: April 2023

Abstract
Background:This study aims to compare the effectiveness of surgical and conservative medical treatments for bezoar ileus in patients with a history of abdominal surgery.
Methods:A total of 80 patients diagnosed with bezoar ileus and with a history of abdominal surgery were included in this study. Patients were divided into two groups based on treatment: conservative medical (n=26) management and surgical (n=54). The primary outcome measure was the resolution of the bezoar ileus without complications. Secondary outcome measures include the length of hospital stay, mortality, and readmission after discharge. Data were collected from electronic medical records and analysed using appropriate statistical methods.
Results:Eighty patients were included in the study, with 26 and 54 patients in treatment groups. The uncomplicated resolution rate was in the surgical group (74,42%), and all complications were related to the postoperative follow-up period. No complication developed during the treatment in 26 patients who received medical treatment. The surgical group also had a significantly shorter hospital stay (mean four days) compared to the medical group (mean seven days) (p < 0.01). Mortality and readmission after discharge rates were similar between the two groups.
Conclusions:Results were similar between surgical treatment and conservative medical treatment in the resolution of bezoar ileus. Surgical treatment was more effective than conservative medical management in reducing hospital stays in patients with prior abdominal surgery. Between the group treated without surgery and the group treated with surgery, respectively, no statistically significant difference was found in terms of mean age, female-male distribution, concomitant disease (excluding cancer history), localization (excluding stomach), bezoar width and length, mortality, incision type (except McBurney), and readmission after discharge (p>0.05). Nonetheless, further prospective studies with larger sample sizes and extended follow-up periods must confirm these findings.

Published: April 2023

Abstract

This research developed models, based on machine learning (MA), for forecasting 16 hours and 4 hours of occurrence of a convective meteorological event (CME), 4 hours for forecasting severity and evaluating the applicability of the optimal models of 12 UTC using thermodynamic instability indices (TII) data extracted from the WRF model with two different types of parameterization configuration in an attempt to develop a30-hour CME forecast model. In the training and testing of the MA algorithms, the classic TIIs (input) were used, obtained from the atmospheric profiles of the Brasilia upper air sounding and atmospheric discharges (output) detected in the study area for the characterization of CME, considering the period from 2012 to 2017. The optimal models applied to the modeled TIIs were evaluated through statistical metrics with configuration II obtaining significant results. For CME detection, the results showed that the best models obtained POD, 1-FAR, F-MEASURE and KAPPA with values respectively greater than 0.90, 0.80, 0.90, 0.80 and BIAS ranging from 0 .89 and 1.12. For the detection of event severity, the model presented the following statistical values (in parentheses): POD (0.82), 1-FAR (0.78), F-MEASURE (0.82), KAPPA (0.59 ) and BIAS (0.97). The results of 16-h and 4-h CME prediction hindcasts (30 days) with developed models demonstrated acceptable performance in identifying the occurrence or non-occurrence of CME and its severity for the study area.

Published: April 2023

Abstract
Orthopedic implant coatings with optimized surface topography and chemistry can achieve favorable osteogenesis and inflammatory responses. In this work, to take advantage of micro/nano-topography and nutrient element Mg, atmosphere plasma spray and post hydrothermal treatment were employed to fabricate two kinds of Mg-incorporated micro/nano-topographical calcium silicate (Mg1-CS and Mg2-CS) coatings. MgSiO3 microspheres composed of nano-flakes were formed on the CS coating surface. We investigated the effects of surface topography and released Mg ion on the protein adsorption and the behaviors of bone mesenchymal stem cells (BMSCs) and RAW264.7 macrophages. Compared with the CS coating, the Mg2-CS coating had larger surface area and pore volume, which favored serum protein adsorption and BMSC adhesion. With higher Mg2+ release, the Mg1-CS coating exerted greater effect on enhancing fibronectin adsorption, integrin activation, and osteogenic behaviors of BMSCs. The gene expression profiles showed that the Mg-incorporated CS coatings could modulate macrophage polarization towards M2 phenotype with Mg2-CS showing greater effect. These results showed that the nanostructured Mg-containing surface can promote osteogenic responses and mitigate inflammatory reactions.

Abstract

Background Anemia management in chronic kidney disease (CKD) is a significant challenge to healthcare professionals worldwide. The extensive management of CKD and its complications are directly linked with a substantial treatment burden and it impacts the quality of life. This study aimed to assess the prevalence and management of anemia and to evaluate the treatment burden and its impact on the quality of life in CKD and Dialysis patients.Methodology A multicenter prospective observational study was conducted in three different hospitals. Initially, 170 patients were recruited in the study with prior consent taken from them. A face-to-face interview was conducted, and a data collection form was distributed among study participants.Results The prevalence of anemia among CKD (stage 3–5) and dialysis patients was 78.7% and 94.7% respectively at baseline. Dialysis patients used more erythropoietin stimulating agents (ESAs) i.e. 38.6% at baseline and 40.8% at month 6 compared to non-dialysis CKD patients. Dialysis patients had a higher treatment burden compared to CKD at baseline (77.4 ± 10.6 vs 59.3 ± 13.3) and at month 6 visit (79.3 ± 11.1 vs 59.1 ± 14.5). The Multiple regression analysis showed that treatment burden had a significant association with age, duration of disease and presence of comorbidity at baseline. There was a strong negative correlation between overall treatment burden and quality of life.Conclusion Anemia was prevalent and its management was suboptimal in the current study. The overall treatment burden score was high in dialysis patients and negatively affects the quality of life.
