AbstractPreoperative cardiorespiratory fitness may influence the recovery after cardiac
procedure. The aim of this study was to investigate the cardiorespiratory
fitness of patients scheduled for elective cardiac procedures, using a
six-minute walk test, and compare the results with a population-based sample of
Finnish adults. Patients (n=234) awaiting percutaneous coronary
intervention or coronary angiography, coronary artery bypass grafting, aortic
valve replacement or mitral valve surgery performed the six-minute walk test.
VO2max was calculated based on the walk test. The patients were
compared to a population-based sample of 60–69-year-old Finnish adults
from the FinFit2017 study. The mean six-minute walk test distances (meters) and
VO2max (ml/kg/min) of the patient groups were:
452±73 and 24.3±6.9 (coronary artery bypass grafting),
499±84 and 27.6±7.2 (aortic valve replacement), 496±85
and 27.4±7.3 (mitral valve surgery), and 519±90 and
27.3±6.9 (percutaneous coronary intervention or coronary angiography).
The population-based sample had significantly greater walk test distance
(623±81) and VO2max (31.7±6.1) than the four patient
groups (all p-values<0.001). All patient groups had lower
cardiorespiratory fitness than the reference population of
60–69-year-old Finnish adults. Particularly the coronary artery bypass
grafting group had a low cardiorespiratory fitness, and therefore might be prone
to complications and challenging rehabilitation after the operation.
Platinum(II) Complexes with Phenylpyridine, Benzo[h]quinoline, and NHC Ligands: Exploration of Ligand Effects on Photophysical Properties
Authors: Strassner Thomas , Pinter Piermaria , Soellner Johannes 
Published: August 2023

AbstractPlatinum(II) complexes with one cyclometalated phenylpyridine or benzo[h]quinoline (C^N) ligand and an N-heterocyclic carbene (NHC) ligand are a robust and readily available class of sky-blue to green phosphorescent triplet emitters. They can be used as a benchmark system to investigate the influence of different ligands on the emissive properties of these [Pt(C^N)(NHC)I] complexes. This new class of compounds was fully characterized by standard techniques. Additionally a solid-state structure could be obtained. Photoluminescence measurements at room temperature revealed the strong emissive behavior of these compounds with quantum yields of up to 80%. The effect of electron-withdrawing and -donating groups on the photophysical properties was examined and rationalized by density functional theory calculations (PBE0/6-311G(d)).
Thiamine-Responsive Megaloblastic Anemia Syndrome Combined with Thalassemia Trait: A Rare Association
Authors: Mabrouk Abdelazim , Aburawi Elhadi H. 
Published: August 2023

Abstract
Introduction Thiamine-responsive megaloblastic anemia syndrome (TRMA, OMIM reference 249270), also known as Rogers' syndrome, is a rare type of anemia characterized by the triad megaloblastic anemia, sensorineural hearing loss, and diabetes mellitus (DM). Disturbance of thiamine transport into cells results from homozygous or compound heterozygous mutations in the SLC19A2 gene.
Case Report We report the case of an 8-year-old girl who presented at age 4 years with anemia. She had a combined hematological profile of microcytic and macrocytic anemia. The parents refused bone marrow aspiration and genetic diagnosis. Hemoglobin electrophoresis established the thalassemia trait. She was later confirmed to have sensorineural deafness and monogenic DM. A tentative TRMA diagnosis was based on megaloblastic anemia, sensorineural deafness, and monogenic DM triad. The patient was treated empirically with a daily dose of thiamine 200 mg; her hemoglobin level normalized, but the deafness and DM did not improve.
Conclusion In routine practice, patients with TRMA must be evaluated thoroughly for other causes of megaloblastic anemia, including therapeutic thiamine trials in the presence of sensorineural deafness or DM. These patients should be followed throughout their life span both for DM and to control their response to thiamine therapy for megaloblastic anemia.

Published: August 2023

SummarySuperiorly based pharyngeal flap is used in eight patients of cleft palate of Velophryngeal Incompetence. Hypernasality and nasal escape in use of oral explosives was substantially reduced following surgery. These patients were subjected to flexible Fibreoptic nasopharyngoscopy to study the morphology of the pharyngeal flap and the role it plays in reducing the amount of velopharyngeal incompetence. Movements of the soft palate and the lateral pharyngeal walls decided the outcome of the result of the Superior Pharyngeal flap surgery. Preoperative Nasopharyngoscopy plays a very important role in deciding the type of Pharyngplasty to be performed.

Fabricated Wire Acrylic Occlusal Splint for the Management of Mandibular and Maxillary Fractures
Authors: Patel Kiran M 
Published: August 2023

SummaryFractures of the mandible and maxilla are usually treated by reduction and immobilization by interdental wiring and intermaxillary fixation. Inability to open the mouth for a period of 5-6 weeks is a disadvantage of this method. Recent techniques like rigid plate fixation help to reduce this period of immobilization of the jaws but it required the necessary equipment and may prove to be expensive in a public hospital system. We have fabricated wire acrylic occlusal splint which has been used in 18 patients for the management of mandibular or maxillary fractures over a period of one year. The mouth remains open during the course of treatment and it greatly helps in oral hygiene. Patient is permitted to take liquids and swallow semi-solid diets by mouth. The splint is removed after bony union is confirmed. We have used this technique in 5 children and 13 adults and has been used both for mandibular and maxillary fractures. There has only been one complication of an occlusal disturbance which was corrected later by dental treatment.

This work presents the design and validation of a vibrating coil magnetometer for the characterization of the field dependence of the critical current density of centimeter-sized bulk superconductors as an alternative to the destructive methods typically used. The magnetometer is also shown to be capable of measuring the magnetic moment in an applied field of up to 5 T for diverse magnetic materials, such as soft and hard ferromagnets and high-temperature superconducting pellets. The vibrating coil magnetometer was first optimized using finite element simulations and calibrated using a commercial vibrating sample magnetometer. The vibrating coil magnetometer was benchmarked with hysteresis measurements of a Nd2Fe14B disk made with a commercial hysteresisgraph, showing good agreement between the different setups. The magnetic hysteresis of a YBa2Cu3O7−x superconducting pellet was measured at 77 K, showing a penetration field of 1 T and an irreversibility field of 4 T. The field dependent critical current density of the superconductor was then inferred from the magnetic hysteresis measurements and extrapolated at low fields. Finally, the resulting critical current density was used to successfully reproduce the measured magnetization curve of the pellet at 2 T with finite element simulations.

Published: August 2023

Abstract
We propose a new method, termed generator coordinate method (GCM)-correlated pair wave function (CPWF), for studying one-dimensional bosons confined in harmonic potentials with contact repulsive interactions. Our approach involves using the effective CPWF as a basis, combined with the GCM to handle complex many-particle correlations accurately. We demonstrate the reliability of our GCM-CPWF wave functions by comparing ground energy and one-body density with those obtained by other numerical methods. Moreover, we present the energy spectrum up to six particles and the occupation number on the harmonic oscillator state. Utilizing these GCM-CPWF wave functions, we explore the properties of the ground and excited states of the many-particle system. Our GCM-CPWF framework is highly flexible and can be generalized to investigate more complex many-particle systems.

Published: August 2023

Abstract
In the development of surface structures, nanowire arrays (NWAS) have been widely studied because of their trapping effect. In this paper, the finite difference time domain (FDTD) method is used to simulate homogeneous and inhomogeneous NWAS. We studied the influence of the structural parameters of InGaN NWAS and inhomogeneous arrays on optical response properties. The optical response includes light absorptivity and cutoff wavelength sensitivity. The simulation results show that the inhomogeneous NWAS can increase the effective transmission distance of light on the surface, thus greatly improving the optical absorption capacity of InGaN NWAS. We can obtain high sensitivity of cut-off wavelength by adjusting the structural parameters of the side nanowires. We find that by reducing the diameters and heights of the side nanowires, a higher light absorption rate can be obtained, which is a 5% improvement compared to uniform NWAS. Therefore, the research in this paper can provide some theoretical reference for the experiment and preparation of InGaN photocathodes.
Numerical modeling of return period waves based on non-linear Boussinesq wave models to support tidal flood studies in the Kedungsepur area
Authors: Khoirunnisa H , Pasma G R , Gumbira G 
Published: August 2023

Abstract
A number of rapid developments and negative effects of climate change in coastal areas have forced its equilibrium system. As a result, tidal floods, high waves, and storms occur more frequently. The goal of this research is to examine nearshore hydrodynamic conditions by using results from the hindcasting procedure. A non-linear Boussinesq (BW) and Spectral Wave (SW) models are used in this study. The models use the manning coefficient, bathymetry data (BATNAS), significant wave height, and wave period calculated by using the hindcasting method. This research commenced by processing wind data from the European Center for Medium-Range Weather Forecasts (ECMWF) from the years 2009 to 2021 with an interval of 3 hours. Then, wave height for return periods 1-, 50- and 100-years are calculated using Gumbel and Fisher-Tippett type I distribution, respectively. The aforementioned approach produced wave heights of 4.23; 6.16; and 6.49 m for return periods 1, 50, and 100 years, respectively. By using this series of wave data, the models predicted that 1.2 m waves propagate close to the nearshore regions.

Published: August 2023

Abstract
The West Banjir Kanal (WBK) River in Semarang City is a river that plays an important role in supporting the various needs of the people of Semarang City. Land use around the river and utilization of WBK river water, cause river water to be contaminated with heavy metals, which have the potential to accumulate in sediments. This study was conducted to analyze and compare the results of the analysis of metal enrichment factors Cd, Cr, Cu, Pb, and Zn in the sediments of the WBK river, Semarang, with 2 different methods. The study was conducted at 7 sampling stations, representing estuaries, middle, and upper reaches of rivers. Sediment was collected with Van Veen Grab, then prepared with wet digestion, then analyzed the metal concentration with AAS. The results showed that the concentration of metals in the sediment at the studied station was still within the limits of natural concentration. The enrichment factor of the metals Cd and Zn is smaller than 1, however, for other metals (Cr, Cu, and Pb) some have exceeded 1. The test results of the comparison of Cr, Cu, and Pb metal enrichment factors in sediments differed markedly for the 2 different methods. But on metals Cd and Zn can not be compared, because the variety of data is 0.

Abstract
Threadfin bream (Nemipterus sp.) is a demersal fish that is widely distributed in Indonesian waters. Protein content of Threadfin bream is 16.85% and fat content of Threadfin bream is 2.2%. High protein content and low-fat content make Threadfin bream potential as raw material for protein hydrolysate. The purpose of this study was to determine the effect of differences in papain enzyme concentration, temperature, and duration of the hydrolysis process on the degree of hydrolysis and to determine the optimal papain enzyme concentration, temperature, and time using Response Surface Methodology. Data analysis was carried out by testing the degree of hydrolysis, protein content, water content, and fat content. Data processing was carried out using the Box Behnken Design and the Response Surface Methodology method. Data processing is supported by the Design Expert 11 software. The recommended model is a quadratic model. The results of the optimization solution for the hydrolysis of Threadfin bream protein were the enzyme concentration 5.833%, the temperature was 55.833°C within 6.967 hours with a desirability of 1. Verification was carried out according to the optimization solution and gave a hydrolysis degree of 48.52%. The verification results obtained are in accordance with the predictions of Design Expert 11. The sample with the highest degree of hydrolysis was tested for protein, water, and fat content and resulted in a protein content of 26.48%, a water content of 41.38%, and a fat content of 0.75%.
Understanding parameters impacting the mechanism leading to spalling around underground excavations in massive rocks under high stress
Authors: Tanjung Ardhymanto Am 
Published: August 2023

Abstract
Underground excavation is required for mining engineering and nuclear waste repository. As the excavation progresses, the stress increases, and brittle failures frequently exist. Brittle failures are arranged into two types: spalling and rock bursting. Spalling in the shape of a V-notch may severely damage the machine and workers involved in its development. This potential hazard can be mitigated by fully representing all parameters that cause spalling in the model. Thus, optimized tunnel design can be achieved. As a result, the company can strike a balance between profit and safety. Several possible results can be proposed by conducting a series of sensitivity studies on a credible model based on a real-world case study of spalling in the Underground Research Laboratory (URL) in Canada. It includes predicting the Depth of Failure (DOF) of spalling by changing two main parameters, particularly strength (tensile and crack initiation) and stress (σ1). The result reveals that increasing tensile strength over UCS decreases DOF, increasing percentages of crack initiation (CI) over UCS decreases DOF, and increasing σmax over UCS increases DOF. Moreover, systematic errors in the generated model can lead to inaccurate DOF estimation. This problem must be approached with engineering judgment in order for the solution to correspond to the actual spalling phenomenon.

Abstract
Microcrystalline Cellulose, MCC, is widely used in pharmaceutical, cosmetics, food, and other industries. This study aims to see changes in the properties that occur in MCC from rice straw waste after transformation using TGJPC-120 isolated bacteria from soil. The biotransformation process was carried out in the bacterial culture flask and placed in an incubator shaker for 2 days at 37 °C, at a rate of 100 rpm. The surface morphology of MCC obtained before and after biotransformation was observed by Scanning Electron Microscopy (SEM). The IR-spectrum and Evaluation of Solid State Interaction of MCC were tested by Fourier Transformation Infra Red (FTIR) Spectrophotometer and Differential Scanning Calorimetry (DSC), respectively. Crystalline characteristics of MCC were analyzed by X-Ray Diffraction technique, and identification of TGJPC-120 was carried out by 16S rRNA analysis. The results showed that DSC thermogram of unbiotransformed and biotransformed-MCC showed the changing in peak width from wide to sharper peaks, reduction in the intensity, and shifts in the melting point. Physical interaction occurs during the biotransformation process to produce a new crystalline phase, and there is no chemical interaction between components during the biotransformation process. The relationship between TGJPC-120 bacteria and Pseudomonas rhizosphaerae Strain IH5 was 92% in the BLAST program tracking database which was determined based on the phylogenetic tree. It can be concluded that the characteristics of MCC before and after the transformation process are different. Studies for process optimization are still ongoing at this time.

Abstract
Waste from laundry washing discharged into waterways without pre-treatment can cause problems that hurt water quality because they contain oxidizing agents such as bleach for clothes. This study aims to determine the effect of milling time variations on the value of the band gap in thin film MnO2/CuO/Fe2O3 and their photocatalytic activity capabilities. This study’s milling time variations were 5 hours, 10 hours, and 15 hours. They were grinding MnO2/CuO/Fe2O3 materials using a High Energy Milling (HEM-E3D) tool to obtain the nano size of these particles. Synthesis of MnO2/CuO/Fe2O3 nanocomposites using the sol-gel method and the spin coating method to manufacture thin films using a glass substrate to be sampled in testing photocatalyst activity. Characterization testing uses a spectroscopy (Uv-Vis) tool to obtain a band gap value. The band gap values were 5 hours milling at 1.87 eV, 10 hours milling at 1.72 eV, and 15 hours milling at 1.64 eV. Here it shows that the longer the milling time, the smaller the band gap energy obtained. Shrinking the energy gap will experience a good photocatalyst process. The results of this study show the effect of the catalyst in degrading pollutants with the best degradability of 50.67%.

Published: August 2023

Abstract
We present a method of tomography in which photon pairs from a device-under-test (DUT) are experimentally characterised by quantum interference with a reference photon pair source; we call this quantum-referenced spontaneous emission tomography (Q-SpET). In Q-SpET, the joint spectral phase (JSP) of photon pairs generated by a DUT can be reconstructed by combining four spectrally resolved interferograms. We demonstrate this theoretically and experimentally, characterising the JSP of a microresonator photon pair source. Our method is fully implemented on a chip, demonstrating the compactness, inherent phase stability, low complexity, and resource efficiency of this method.
Accuracy of frozen section remote subspecialty consultation using real-time telepathology and whole-slide imaging in gynecologic cases
Authors: Treece Charisse Liz B , Filipek Jennifer , Makker Jitin , Moatamed Neda A , Rodriguez Erika F 
Published: August 2023

Abstract

Objectives
Intrapathology consultation is recommended for complex cases during frozen section (FS) as routine practice. In our institution, solicited second opinions were traditionally provided by in-person consultation (IPC). Whole-slide imaging (WSI) was implemented in 2018 as an alternative but replaced by videoconferencing in 2020. Here, we assess the accuracy of remote FS consultation using these digital modalities vs IPC.

Methods
Gynecologic FS cases over a 4-year period overseen by 2 intraoperative consultants were grouped by consultation method: (1) IPC, (2) WSI, and (3) videoconferencing. Accuracy was determined by concordance between the FS and final report diagnoses. Turnaround time between the 3 groups was analyzed using SPSS statistical software (IBM).

Results
Using WSI and videoconferencing, 100% concordance was observed, while the IPC group had a 98.5% concordance rate. Videoconferencing, however, showed longer turnaround times (mean, 45.59 minutes) than IPC (mean, 33.36 minutes). Although turnaround time positively correlated with the number of FS specimens, blocks, and H&E slides per case, no statistically significant differences in the number of specimens, blocks, and H&E slides generated were found among the consultation methods.

Conclusions
Even though turnaround time using videoconferencing is longer, the accuracy of WSI and videoconferencing for remote FS consultation is equivalent to IPC. It is therefore a safe method for conducting intrapathology FS consultation in challenging surgical cases.
