Confined Electrochemical Finishing of Additive-Manufactured Internal Holes with Coaxial Electrolyte Flushing
Authors: Zhao Chenhao , Qu Ningsong , Tang Xiaochuan
Published: November 2021

Adhered powders and undesirable surface quality represent significant challenges for additive manufacturing (AM) technology. AM internal surface finishing is more difficult owing to the poor visibility of internal geometries and the inconvenient manipulation to machine tools. This paper proposed a confined electrochemical finishing process with a coaxial electrolyte flushing manner to remove the AM internal surface asperity. The insulation was conducted in the non-machining area of cathode to cease its electrochemical reaction which consumed the electric charge to generate gas bubbles, and the electrochemical dissolution could be confined within the AM internal hole. More intensive electrochemical dissolution was performed to the AM surface asperity and thus higher material removal and better surface finishing enhancement could be achieved. The coaxial electrolyte flushing manner created a uniform and efficient flow field to facilitate the discharge of electrolytic products. This technique could eliminate the partially melted powders adhered to the AM internal surface and reduce their Ra from 15.620 μm to 3.494 μm and Rz from 78.402 μm to 19.272 μm. The AM internal hole with a high aspect ratio of 10 could be well handled by this process to eliminate the adhered powders from its internal surface.

Published: November 2021

Working conditions such as lubrication, preload, and rotational speed have important influence on vibration and temperature rise of the spindle motor. In this study, controlled variable experiments are carried out on the silicon nitride (Si3N4) full‐ceramic ball bearing and steel bearing of the same type, and the vibration signal characteristics and temperature rise of the spindle motor are tested and analysed, by changing the lubrication conditions, preloads, and rotational speeds of the spindle motor. Through the research, it is found that as the rotational speed increases, the vibration velocity of the Si3N4 full‐ceramic bearing spindle motor under different preloads and lubrication conditions shows an overall increasing trend; kurtosis generally presents a downward trend and gradually flattens, indicating that although the vibration velocity increases at high speeds, the vibration signal shows a relatively stable state. As the rotational speed increases, the difference of vibration velocity under the condition of applying preload and no preload decreases, indicating that the influence of preload on the vibration of full‐ceramic bearing spindle motor decreases with the increase in rotational speeds. At the same time, it is found that fr and 5fr have greater impact on the vibration of full‐ceramic bearing spindle motor, where fr is the frequency of the bearing in normal operation, and 5fr is 5 times of the normal operating frequency. Lubrication conditions have little effect on the temperature rise of full‐ceramic bearing spindle motor, and the temperature rise under nonlubricated conditions is even slightly lower than that under grease lubrication conditions. The research results show that the vibration velocity and temperature rise of Si3N4 full‐ceramic bearing spindle motor are less than those of steel bearing with the same type, indicating that full‐ceramic bearing has better performance than steel bearing under the same working conditions.

Published: November 2021

Fragile ancient buildings are recognized as an eloquent testimony to human civilization, and their safety should arouse more attention. According to the special case of adjacent blasting construction, the assessment model should be essentially built to assess the effect of tunnel blasting on the safety of the ancient buildings. To analyze the structural safety of ancient buildings under blasting vibration and to protect the precious ancient buildings, a risk assessment model of ancient buildings with 20 relevant assessment indexes was initiatively built in this study. To be specific, the relative factors of blasting, the factors of ancient buildings, and other factors (e.g., religion) were comprehensively considered in the model. Subsequently, the risk level and weight were calculated more systematically and quantitatively by adopting the optimized optimal comprehensive method integrating the G1 method and the entropy method. Lastly, the overall risk value was determined by applying the fuzzy gray method. Afterward, the value was adopted to assess the safety of the Asoka Temple, the only existing temple named after the Indian King Asoka in China, as an attempt to verify the feasibility of this model. Besides, the Asoka tunnel was around it. As demonstrated from the results, the age of the buildings maximally impacted the safety of ancient buildings, and the safety level of the Asoka Temple was “relatively safe.” The present study built an effective model to assess the safety of ancient buildings under adjacent subway blasting construction, which could help improve the efficiency and accuracy of assessments.

Published: November 2021

There is not a described method to count the core label of c‐Fos‐positive neurons, avoiding false‐positive and false‐negative results. The aim of this manuscript is to provide guidelines for a secure and accurate method to calculate a threshold to select which core of c‐Fos‐positive neurons marked by immunofluorescence has to be scored. A background percentage was calculated by dividing the intensity value (0 to 255) of the core of c‐Fos‐positive neurons by its surrounding background from the 8‐bit images obtained in a previous study. Using the background percentage from 20% up to 98%, raising 2% once for each score, as threshold to choose which core has to be counted, a script was written for the R program to count the number of the c‐Fos‐positive neurons and the comparison between control and experimental groups. The differences of the average number of the core counted c‐Fos‐positive neurons between control and experimental groups, at all thresholds studied, showed a rising value related to an increase of the background percentage threshold as well as a decrease of its p value related to an increase of the threshold of background percentage. For the smallest thresholds (high intensity of label), the differences between groups are suppressed (false negative). However, for the biggest thresholds (nonspecific label), these differences are always the same (false positive). Therefore, to avoid the false‐negative and the false‐positive values, it was chosen as the threshold of 62% the inflection point of the linear regression, which is equally different from the biggest and smallest values of the differences between groups.

Published: November 2021

The magnetic field can act as a suitable control parameter for heat transfer and fluid flow. It can also be used to maximize thermodynamic efficiency in a variety of fields. Nanofluids and porous media are common methods to increase heat transfer. In addition to improving heat transfer, porous media can increase pressure drop. This research is a computational simulation of the impacts of a magnetic field induced into a cylinder in a porous medium for a volume fraction of 0.2 water/Al2O3 nanofluid with a diameter of 10 μm inside the cylinder. For a wide variety of controlling parameters, simulations have been made. The fluid flow in the porous medium is explained using the Darcy-Brinkman-Forchheimer equation, and the nanofluid flow is represented utilizing a two-phase mixed approach as a two-phase flow. In addition, simulations were run in a slow flow state using the finite volume method. The mean Nusselt number and performance evaluation criteria (PEC) were studied for different Darcy and Hartmann numbers. The results show that the amount of heat transfer coefficient increases with increasing the number of Hartmann and Darcy. In addition, the composition of the nanofluid in the base fluid enhanced the PEC in all instances. Furthermore, the PEC has gained its highest value at the conditions relating to the permeable porous medium.

Published: November 2021

As neurological complications associated with COVID-19 keep unfolding, the number of cases with COVID-19-associated de novo movement disorders is rising. Although no clear pathomechanistic explanation is provided yet, the growing number of these cases is somewhat alarming. This review gathers information from 64 reports of de novo movement disorders developing after/during infection with SARS-CoV-2. Three new cases with myoclonus occurring shortly after a COVID-19 infection are also presented. Treatment resulted in partial to complete recovery in all three cases. Although the overall percentage of COVID-19 patients who develop movement disorders is marginal, explanations on a probable causal link have been suggested by numerous reports; most commonly involving immune-mediated and postinfectious and less frequently hypoxic-associated and ischemic-related pathways. The current body of evidence points myoclonus and ataxia out as the most frequent movement disorders occurring in COVID-19 patients. Some cases of tremor, chorea, and hypokinetic-rigid syndrome have also been observed in association with COVID-19. In particular, parkinsonism may be of dual concern in the setting of COVID-19; some have linked viral infections with Parkinson’s disease (PD) based on results from cerebrospinal fluid analyses, and PD is speculated to impact the outcome of COVID-19 in patients negatively. In conclusion, the present paper reviewed the demographic, clinical, and treatment-associated information on de novo movement disorders in COVID-19 patients in detail; it also underlined the higher incidence of myoclonus and ataxia associated with COVID-19 than other movement disorders.

Published: November 2021

This study intends to examine different dynamics of the chaotic incommensurate fractional‐order Hopfield neural network model. The stability of the proposed incommensurate‐order model is analyzed numerically by continuously varying the values of the fractional‐order derivative and the values of the system parameters. It turned out that the formulated system using the Caputo differential operator exhibits many rich complex dynamics, including symmetry, bistability, and coexisting chaotic attractors. On the other hand, it has been detected that by adapting the corresponding controlled constants, such systems possess the so‐called offset boosting of three variables. Besides, the resultant periodic and chaotic attractors can be scattered in several forms, including 1D line, 2D lattice, and 3D grid, and even in an arbitrary location of the phase space. Several numerical simulations are implemented, and the obtained findings are illustrated through constructing bifurcation diagrams, computing Lyapunov exponents, calculating Lyapunov dimensions, and sketching the phase portraits in 2D and 3D projections.
A Heuristic Approach for Two‐Dimensional Rectangular Cutting Stock Problem considering Balance for Material Utilization and Cutting Complexity
Authors: Wu Dianjian , Yang Guangyou
Published: November 2021

The common staged patterns are always required during the cutting process for separating a set of rectangular items from rectangular plates in manufacturing industries. Two‐staged patterns can reduce cutting complexity at the expense of material utilization; three‐staged patterns do the opposite. Combining these two types of staged patterns may be a good balance for two contradictory objectives of material utilization and cutting complexity. A heuristic approach is proposed to solve the two‐dimensional rectangular cutting stock problem with a combination of two‐staged general patterns (2SGP) and three‐staged homogenous patterns (3SHP). Firstly, the 2SGP and 3SHP are constructed by using recursive techniques. The pattern with the larger value is selected as the candidate pattern. Then, the value of each item is corrected according to the current candidate pattern. A cutting plan accurately satisfying all items demand is obtained by using the sequential heuristic algorithm. Finally, the cutting plan with a minimum number of used plates is achieved by applying the iterative algorithm. The computational results indicate that the proposed heuristic approach is more effective in material utilization and cutting complexity than the two published algorithms with staged patterns.

Published: November 2021

Groundwater flow in an aquifer has frequently been found to be non-Darcian by performing in situ tests. A novel analytic model is proposed in this study for describing the unsteady non-Darcian flow in a confined aquifer by taking advantage of the observed flow rate and injection pressure during the constant head packer test. A linearization approximation of the Izbash equation is used to approximate the nonlinear term in the governing equation. This analytic model is applied to describe the non-Darcian flow in the interlayer staggered zone at the Baihetan hydropower station, China. The test results inversed by the genetic algorithm show that non-Darcian flow happened during the test under the injection pressure 0.3 MPa with the power index

Sophora viciifolia Hance is an edible plant used in traditional Chinese medicine. Sophocarpine, a tetracyclic quinolizidine alkaloid, is one of the most abundant active ingredients in Sophora viciifolia Hance. Here, we study the analgesic and anti‐inflammatory effects, as well as the acute toxicity of sophocarpine from Sophora viciifolia Hance in mice. Sophocarpine (20, 40, and 80 mg/kgbw) significantly prolonged the delay period before a hot plate reaction occurred (all P < 0.05), and the delay before a tail‐flick response was induced by a warm bath (P < 0.05; P < 0.01). Sophocarpine (40, 80 mg/kg) resulted in dose‐dependent inhibition of the writhing reaction induced by acetic acid in mice (P < 0.05; P < 0.001, respectively). Sophocarpine (80 mg/kg) reduced the total duration of a formalin‐induced pain response (P < 0.05). Sophocarpine prolonged the foot‐licking latency of mice after the hot plate reaction, and this effect was antagonized by calcium chloride and enhanced by verapamil. Sophocarpine (20, 40, and 80 mg/kg) significantly inhibited xylene‐induced ear edema (P < 0.01; P < 0.001; P < 0.001, respectively) and the penetration of acetic acid‐induced dye into the peritoneal cavity (P < 0.01; P < 0.01; P < 0.001, respectively). It also reduced the levels of proinflammatory cytokine interleukin (IL)‐1β, IL‐6, and prostaglandin E2 (P < 0.05, P < 0.01, P < 0.001) and those of serum nitric oxide (P < 0.05). The results of this study suggest that sophocarpine possesses certain analgesic and anti‐inflammatory activities, which may be related to calcium and inhibition of the secretion of inflammatory factors.

Identification of the association between Early Childhood Caries (ECC) and Iron Deficiency Anaemia (IDA) will aid paediatricians and paediatric dentists to enhance health promotion measures to reduce the related morbidity in children. This systematic review aims to determine an evidence-based association between ECC and IDA. A systematic search was carried out from MEDLINE via PubMed, EMBASE, LILACS, Cochrane Oral Health Group’s Specialized Register, CINAHL via EBSCO, Web of Science, and Scopus up to May 2020. Hand searching and grey literature screening were also conducted. Cross-sectional, case-control, and cohort studies in English language which assessed the association was included. Two reviewers independently assessed the study quality and extracted the outcome data. A total of 1,434 studies were identified. Fourteen studies qualified for qualitative review and 7 of them for a meta-analysis. In comparison with children not affected by ECC, those affected had an increased likelihood of IDA (OR = 6.07 [3.61, 10.21]). The meta-analysis showed no statistical difference when comparing blood parameters (Hb, MCV, and serum ferritin) in children with and without ECC. This systematic review demonstrates an association between ECC and increased odds of IDA rather than it being the cause for IDA. Further longitudinal studies with robust methodology are required to determine an evidence-based association.

Covid-19 is a new infectious viral illness. The first one appeared in Wuhan, and within two months, it became a pandemic. Medical diagnosis is confirmed by fever, cough, shortness of breath, combined with neutrophil ratio lymphocyte analysis and chest x-ray or chest ­C.T. radiology imaging, with a ground-glass appearance. C.T. scans are not widely available in hospitals in Indonesia. Many hospitals only own x-ray for covid-19 as radiologic diagnostic imaging. With digital imaging capabilities, Due to the similarity of applications such as the radiological workstation, Adobe Photoshop Express will improve the capacity to diagnose Covid-19 from a chest x-ray. Adobe Photoshop Express has outstanding digital processing capabilities to enhance the presentation of images so that the efficiency of diagnosing plain x-ray thorax image cases with Covid-19 becomes easier and more manageable.

Background:

Transient pulmonary congestion during exercise is emerging as an important determinant of reduced exercise capacity in heart failure with preserved ejection fraction (HFpEF). We sought to determine whether an abnormal cardiac energetic state underpins this process.

Methods:

We recruited patients across the spectrum of diastolic dysfunction and HFpEF (controls, n=11; type 2 diabetes, n=9; HFpEF, n=14; and severe diastolic dysfunction attributable to cardiac amyloidosis, n=9). Cardiac energetics were measured using phosphorus spectroscopy to define the myocardial phosphocreatine to ATP ratio. Cardiac function was assessed by cardiovascular magnetic resonance cine imaging and echocardiography and lung water using magnetic resonance proton density mapping. Studies were performed at rest and during submaximal exercise using a magnetic resonance imaging ergometer.

Results:

Paralleling the stepwise decline in diastolic function across the groups (E/e′ ratio;
P

<0.001) and a reduction in phosphocreatine/ATP ratio (control, 2.15 [2.09, 2.29]; type 2 diabetes, 1.71 [1.61, 1.91]; HFpEF, 1.66 [1.44, 1.89]; cardiac amyloidosis, 1.30 [1.16, 1.53];
P
<0.001). During 20-W exercise, lower left ventricular diastolic filling rates (r=0.58;
P
<0.001), lower left ventricular diastolic reserve (r=0.55;
P
<0.001), left atrial dilatation (r=–0.52;

P
<0.001), and right atrial dilation (r=–0.71;
P
<0.001) were all linked to lower phosphocreatine/ATP ratio. Along with these changes, pulmonary proton density mapping revealed transient pulmonary congestion in patients with HFpEF (+4.4% [0.5, 6.4];
P
=0.002) and cardiac amyloidosis (+6.4% [3.3, 10.0];
P

P
=0.89) or type 2 diabetes without HFpEF (+0.8% [–1.7, 1.9];
P
=0.82). The development of exercise-induced pulmonary congestion was associated with lower phosphocreatine/ATP ratio (r=–0.43;
P
=0.004).

Conclusions:

A gradient of myocardial energetic deficit exists across the spectrum of HFpEF. Even at low workload, this energetic deficit is related to markedly abnormal exercise responses in all 4 cardiac chambers, which is associated with detectable pulmonary congestion. The findings support an energetic basis for transient pulmonary congestion in HFpEF.

Background:

In the past 2 decades, hypertension control in the US population has not improved and there are widening disparities. Little is known about progress in reducing hospitalizations for acute hypertension.

Methods:

We conducted serial cross-sectional analysis of Medicare fee-for-service beneficiaries age 65 years or older between 1999 and 2019 using Medicare denominator and inpatient files. We evaluated trends in national hospitalization rates for acute hypertension overall and by demographic and geographical subgroups. We identified all beneficiaries admitted with a primary discharge diagnosis of acute hypertension on the basis of International Classification of Diseases codes. We then used a mixed effects model with a Poisson link function and state-specific random intercepts, adjusting for age, sex, race and ethnicity, and dual-eligible status, to evaluate trends in hospitalizations.

Results:

The sample consisted of 397 238 individual Medicare fee-for-service beneficiaries. From 1999 through 2019, the annual hospitalization rates for acute hypertension increased significantly, from 51.5 to 125.9 per 100 000 beneficiary-years; the absolute increase was most pronounced among the following subgroups: adults ≥85 years (66.8–274.1), females (64.9–160.1), Black people (144.4–369.5), and Medicare/Medicaid insured (dual-eligible, 93.1–270.0). Across all subgroups, Black adults had the highest hospitalization rate in 2019, and there was a significant increase in the differences in hospitalizations between Black and White people from 1999 to 2019. Marked geographic variation was also present, with the highest hospitalization rates in the South. Among patients hospitalized for acute hypertension, the observed 30-day and 90-day all-cause mortality rates (95% CI) decreased from 2.6% (2.27–2.83) and 5.6% (5.18–5.99) to 1.7% (1.53–1.80) and 3.7% (3.45–3.84) and 30-day and 90-day all-cause readmission rates decreased from 15.7% (15.1–16.4) and 29.4% (28.6–30.2) to 11.8% (11.5–12.1) and 24.0% (23.5–24.6).

Conclusions:

Among Medicare fee-for-service beneficiaries age 65 years or older, hospitalization rates for acute hypertension increased substantially and significantly from 1999 to 2019. Black adults had the highest hospitalization rate in 2019 across age, sex, race and ethnicity, and dual-eligible strata. There was significant national variation, with the highest rates generally in the South.
Change in angle of depressed medial tibial plateau following extra-articular mechanical realignment surgery in children with Blount’s disease who presented late for treatment

Introduction:

The aim of this study was to determine whether any change in degree of medial tibia plateau depression after extra-articular mechanical realignment surgery was observed in children with Blount’s disease who presented late for treatment in their adolescence and young adulthood.

Methods:

We retrospectively reviewed the radiographic parameters of 22 patients (32 lower limbs) with Blount’s disease who underwent gradual correction of deformity using a ring external fixator without surgical elevation of the depressed medial tibial plateau at a mean age of 15 (range 10–37) years. Preoperative and postoperative angles of depressed medial tibia plateau (ADMTPs) of the same patient were compared for any significant change. Normally distributed data were analysed using Student’s t-test when comparing two groups or one-way analysis of variance when comparing more than two groups. Skewed data were analysed using Mann–Whitney test.

Results:

After extra-articular mechanical alignment surgery, statistically significant improvements in medial tibial plateau depression were seen in the infantile (P = 0.03) and juvenile (P = 0.04) Blount’s subgroups. Change in ADMTP was greater in patients who were operated on at age <17 years, before skeletal maturity (P = 0.001). The improvement was likely due to ossification of unossified cartilage at the posteromedial proximal tibia and the remodelling potential of proximal tibia physis after mechanical realignment.

Conclusion:

Improvement of medial tibia plateau depression is possible after mechanical realignment without surgical hemiplateau elevation in cases of infantile and juvenile Blount’s disease that present late for treatment, especially when the operation is performed before 17 years of age.
Biographies and Bodies of Pupils of the Amsterdam Maritime Institute, 1792–1943
Authors: Quanjer Björn , Kok Jan
Published: November 2021

In this article, the authors describe and explore the dataset Pupils of the Amsterdam Maritime Institute 1792–1943, which is based on the Comportementboeken of the Amsterdam Maritime Institute. These records contain biographical information and bodily measurements of aspirant sailors between 12 and 20 years of age. The authors have linked the records (N = 5439) to enrolment records and the examinations for the military draft, which provides unique data on historical adolescent growth rates. Apart from anthropometric research, the dataset can be used for different kinds of studies into the background and early careers of Dutch sailors.
The oldest Diptera (Insecta) from the Upper Buntsandstein (early Middle Triassic) of Europe
Authors: LUKASHEVICH ELENA D.
Published: November 2021

The fossil record of Triassic Diptera is still poor, with the oldest dipteran assemblage described from the Upper Buntsandstein of the ‘Grès à Voltzia’ Formation (early Anisian, France). From the stratigraphically closest insect fauna of the Röt Formation of Lower Franconia, Germany, the first Diptera, Bashkonia franconica gen. et sp. nov. is described based on an isolated wing. The new genus is assigned to the family Nadipteridae, bridging the gap between two other genera included.
