Authors: Mujiyanti Dwi Rasy , Santoso Uripto Trisno , Saptarini Mutiara Dwi , Emi Nur Heirani
Published: December 2022

Nano-silica (NS) from rice husk ash was successfully synthesized using a sol-gel process with the addition of polyethylene glycol (PEG) 6000 and polyvinyl alcohol (PVA) as a template. The purpose of this study is to investigate the properties of NS functional groups and the effect of PEG6000 and PVA concentrations (5%, 10%, and 15% (b / v)) on the size, morphology, and distribution of nanosilica. The functional groups of NS are characterized by Fourier transform infrared (FTIR), the size and morphology of NS are characterized by scanning electron microscopy (SEM). In contrast the size analyzer characterizes the particle size distributionof particulate matter (PSA). The results indicated that the addition of PEG-6000 and PVA affected the size and morphology of NS. The FTIR spectra showed the presence of silanol (Si-OH) and siloxane (Si-O-Si) groups. According to the SEM results, the morphology of NS -PEG is round and relatively more uniform than the amorphous morphology of NS-Control and NS-PVA. Instead of PEG-6000, Sol-gel PVA can be obtained with a narrow particle size distribution.

Published: December 2022

Beta-thalassemia therapy is developed by increasing γ-globin production which binds to α-globin to form haemoglobin fetal (HbF). Meanwhile, DNA methyltransferase 1 (DNMT1) and lysine specific demethylase 1 (LSD1) play an important role in silencing the HbF gene by inhibiting the production of HbF and inducing haemoglobin subunit alpha (HbA) expression. 6-Shogaol and curcumin induce HbF by inhibiting signal transducer and activator of transcription 3 (STAT3) expression. Therefore, this study predicts the interaction between 6-shogaol and curcumin on DNMT1 and LSD1. The protein structure of DNMT1 (3SWR) and LSD1 (6KGP) was prepared by removing the water molecules, while the validation step was performed by separating protein from native ligands (sinefungin for 3SWR and flavine-adenine dinucleotide (FAD) for 6KGP) in new protein data bank files. Furthermore, the protein was docked with a native ligand to obtain grid box coordinates, while the root means standard deviation (RMSD) was calculated from the conformation results of the validation process. 6-Shogaol and curcumin were docked with coordinates of the validation results, and the best conformation was visualized with Discovery Studio. The validation step results in the RMSD value of 0.861Å and 1.410Å for DNMT1 and LSD1, respectively. The binding affinity of 6-shogaol and curcumin on DNMT1 was -6.5 kcal/mol and -8.0 kcal/mol, respectively. Furthermore, the binding affinity of 6-shogaol and curcumin on LSD1 was -8.2 kcal/mol and -10.1 kcal/mol, respectively. Amino acid residues found in DNMT1 interaction include Gly1147, Phe1145, Glu1168, Asn1278, Pro1225, Leu1151, Val1580, Ala1579, Asn1578, Trp1170, and Ala1579; meanwhile, Val288, Ser289, Arg310, Gly285, Thr624, Leu659, Lys661, Arg316, Leu625, Tyr761, Trp751, Gly330, and Leu659 were found in LSD1. This study showed that curcumin has the potential to inhibit DNMT1 as well as LSD1 proven by lower bonding energy and stronger bond types compared to sinefungin and FAD native ligands and other DNMT1 and LSD1 inhibitors.

Authors: Nugrahini Elisabeth , Mahardiani Lina , Setiarini Ida , Anjelina Wieke Helma
Published: December 2022

Heavy metal wastes cause water pollution. One of them is very toxic arsenic heavy metal waste; thus, treating them before they are released freely into the waters is necessary. In this case, the manufacture of carbon nanofibers (CNF) from sugar palm fiber waste is an innovation that can produce adsorbents to remediate heavy metals, thereby increasing the use value of sugar palm fiber waste. Carbon nanofiber from palm fiber (Arenga pinnata) was modified with ZnO metal, with varying concentrations of 0.1%, 1%, and 10%, in 1 gram of carbon nanofiber. Carbon nanofibers were made by carbonizing sugar palm fibers at 300oC for two hours. Furthermore, wet impregnation was carried out with Zn(CH3COO)2.2H2O and ended with calcination at 250oC for an hour, resulting in black nanofiber powder. This research was conducted to determine the effect of ZnO concentration on the characteristics of the carbon nanofiber produced and its effectiveness in remediating heavy metal arsenic. The ZnO/carbon nanofiber adsorbent material was then characterized using FTIR, XRD, and SEM analyses. Determination of the absorption of ZnO/carbon nanofibers on heavy metal arsenic was also assessed employing AAS analysis.

Authors: Sari Sri Adelila , Hawari Dinda
Published: December 2022

Fingerprints are an identification tool in forensic science because of their unique properties. Unfortunately, some of the chemicals used in fingerprint powders are toxic and pose a potential health hazard. This study was conducted to analyze the ability of ZnO nanoparticles to identify latent fingerprints. ZnO nanopowder was synthesized with lime leaf extract using the green synthesis method with double-distilled water solvent and characterized by FT-IR at a wavenumber of 4000-400 cm-1 and SEM-EDX analysis to provide information about the morphology and to detect the elemental composition nanoparticles. The average particle diameter through SEM was around 173.4 nm and formed a spherical with a rough surface with beige color. Identification of latent fingerprints using the powder dusting method on various porous surfaces (craft paper and greaseproof paper) and non-porous surfaces (glass preparations, aluminium foil, and compact disk) shows visualization with the characteristics of the ridges that look good and clear. The study showed the highest frequency of loops (47%), followed by double loops (20%), plain whorls (30%), and central pocket whorls pattern (3%) from 30 fingerprint samples consisting of 14 men and 16 women. Development identification fingerprints using TiO2 show visualization more clearly because color contrast from bright white color and detail ridges is shown better with ZnO nanopowder.

Published: December 2022

The Jakarta Smart City Plan is an effort by the DKI Jakarta Provincial Government to use information technology in government sectors. One of the strategies developed by DKI Jakarta Provincial authorities, especially at the Department of Population and Civil Registration is the Alpukat Betawi (Direct Access to Fast and Accurate Population Documentation Service) app. This application provides various access to population licensing services and civil registration for residents of Jakarta. The purpose of this study is to analyze the implementation of e-government in the provision of public services within the framework of population administration services. Descriptive qualitative methods were used in this study. The data comes from a literature study, the results of observations and interviews. The results show that the use of the Alpukat Betawi app is not yet optimal. It has been found that limitations and barriers lead to people not knowing and understanding how to access online administrative services, lack of socialization of online application based systems, synchronization of population databases remains weak, and lack of human resources and IT system facilities due to budget constraints. This research will provide recommendations to improve the public service system to increase accountability, professionality, effectiveness and transparency of public services. In this case, DKI Jakarta Provincial of The Department of Population and Civil Registration should take action to plan, develop, and innovate in improving population online services and increasing civic engagement.
Possible genetic resemblance among white coated shepherd dogs such as Turkish Akbash Shepherd, Polish Tatra, Kuvasz, Chuvach, and Central Asian Shepherd Dog
Authors:   Faculty of Engineering, Ardahan University, Ardahan, Turkey, Yılmaz Orhan
Published: December 2022

According to scientists, the dog was domesticated in Asia and spread to other parts of the world from this continent. Turks are also from Central Asia. It is believed that the homeland of the Turkish Akbash Shepherd Dog is Central Asia. The Turks may have taken these white-skinned shepherd dogs to other parts of Europe as well. It is also believed that the Hungarians came from the Hun Turks, one of the ancient Turkish tribes. When the ancestors of the Hungarians came to this region, they may have brought white-skinned dogs, which are now called Kuvasz Dogs. Hungary, Slovakia and Southern Poland are in the same basin and dogs called Kuvasz, Chuvach and Tatra are bred in the countries of this basin, respectively. Kuvasz, Chuvach and Tatra were brought by the Hun Turks and may be dogs of the same origin. This paper claims “All white-skinned shepherd dogs are descended from the Central Asian Shepherd Dog, which was taken by the Turks from Central Asia to other countries.” If this hypothesis can be proven as a result of genetic analysis, the results of this research will not only serve animal science, but also anthropology for humanity.

Generation II Coastal Risk Model (G2CRM)
Authors:   Coastal and Hydraulics Laboratory (U.S.)
Published: December 2022

The U.S. Army Corps of Engineers (USACE or Corps) has a mission to manage flood risks: “The USACE Flood Risk Management Program (FRMP) works across the agency to focus the policies, programs and expertise of USACE toward reducing overall flood risk. This includes the appropriate use and resiliency of structures such as levees and floodwalls, as well as promoting alternatives when other approaches (e.g., land acquisition, flood proofing, etc.) reduce the risk of loss of life, reduce long-term economic damages to the public and private sector, and improve the natural environment.” As a part of that mission, the Institute for Water Resources (IWR) in cooperation with other Corps groups has developed the Generation II Coastal Risk Model (G2CRM) to support planning-level studies of hurricane protection systems (HPS). The G2CRM is distinguished from other models currently used for that purpose by virtue of its focus on probabilistic life cycle approaches. This allows for examination of important long-term issues including the impact of climate change and avoidance of repetitive damages. Key features of the model include the ability to use readily available data from existing sources and corporate databases and integration with geographic information systems (GIS). The G2CRM generates a wide variety of outputs useful for estimating damages and costs, characterizing and communicating risk, and reporting detailed model behavior, in the without-project condition and under various plan alternatives for the with-project condition.
Helicopter rotor blade planform optimization using parametric design and multi-objective genetic algorithm
Authors: Wenren Yonghu , Lim Joon , Allen Luke , Haehnel Robert , Dettwiler Ian
Published: December 2022

In this paper, an automated framework is presented to perform helicopter rotor blade planform optimization. This framework contains three elements, Dakota, ParBlade, and RCAS. These elements are integrated into an environment control tool, Galaxy Simulation Builder, which is used to carry out the optimization. The main objective of this work is to conduct rotor performance design optimizations for forward flight and hover. The blade design variables manipulated by ParBlade are twist, sweep, and anhedral. The multi-objective genetic algorithm method is used in this study to search for the optimum blade design; the optimization objective is to minimize the rotor power required. Following design parameter substitution, ParBlade generates the modified blade shape and updates the rotor blade properties in the RCAS script before running RCAS. After the RCAS simulations are complete, the desired performance metrics (objectives and constraints) are extracted and returned to the Dakota optimizer. Demonstrative optimization case studies were conducted using a UH-60A main rotor as the base case. Rotor power in hover and forward flight, at advance ratio 𝜇𝜇 = 0.3, are used as objective functions. The results of this study show improvement in rotor power of 6.13% and 8.52% in hover and an advance ratio of 0.3, respectively. This configuration also yields greater reductions in rotor power for high advance ratios, e.g., 12.42% reduction at 𝜇𝜇 = 0.4.

The purpose of this exploratory case study is to consider from peer tutors’ perspective the relevance of information literacy (IL) in their roles as tutors, students and in their everyday lives. The research used a qualitative methodology, wherein nine participants shared thoughts and reflections in course discussion forums in response to six online modules, each outlining one the the six frames of the ACRL information literacy framework. The data-gathering phase of the study was bookended by focus groups that were also recorded. Analysis of these various discussions reveals that while tutors see the relevance of IL in their everyday lives, their responses in terms of their roles as tutors and students varies depending on the nature of their program. The need to budget research time efficiently in response to a heavy course load prevents some from pursuing information more broadly or deeply than strictly necessary. The paper considers implications of these insights for further inquiry into the library’s role in advancing IL development in a polytechnical environment.
A Complete Model for Mesh Pad Mist Eliminators in Oil and Gas Processing by Analogy with Distillation Packing
Authors: Grim Charles Logan , Al-Zubail Ahmed
Published: December 2022

Current models for pressure drop in mesh pads are not adequate for pressure drop critical applications and do not cover the flooding regime commonly encountered when mesh pads are used as a coalescer. In addition, these models do not predict the flooding capacity of mesh pads. Pressure drop and capacity models for mesh pads are presented and compared with literature experimental data for fluid systems ranging from atmospheric pressure to 85-bar natural gas. The experimental data were successfully correlated from the region of countercurrent flow through to flooding of the mesh pads. The model captures, quantitatively, the pressure drop and liquid holdup in mesh pads as well as predicting the flood point of the mesh. When combined with a separation performance method, flooding in layered mesh pads can also be predicted. The model covers both conventional and co-knit mesh pads and can be adapted to other packing geometries, requiring only dry pressure drop data.

We recently reported that sub-acute myocarditis occurred following the initial two doses of mRNA-based vaccination against COVID-19 (0.3 mL Comirnaty®) in elderly Japanese patients with cardiac dysfunction. The present retrospective study of 76 patients shows that myocarditis following the initial doses persisted for 12 months, was associated with low levels of neutralizing antibodies, and was ameliorated by reducing the third vaccine dose. Low neutralizing antibody levels (<220 U/mL) after the initial doses were an independent predictor of persistent clinical events, defined as death or marked changes in the brain natriuretic peptide levels. When the third dose was reduced (0.1 mL), changes in the brain natriuretic peptide levels were significantly smaller (P = 0.02, n = 25), no deaths occurred due to heart failure, and neutralizing antibody levels increased 41-fold (P < 0.001) compared with the initial doses. Reduced booster doses could facilitate the worldwide distribution of mRNA vaccines.

Published: December 2022

This research conducted to determine which minerals might be deficient or excess in Iranian Sistani cattle diet based on mostly-grazed plant species. In late spring season of Sistan basin (located in southwestern Iran), four sites including Saberi, Lorg-Bagh, Kuh-Khaje and Zahak were selected and six major forage species consumed by Sistani cows including Phragmites australis, Bolboschoenus glaucus, Aeluropus lagopoides, Tamarix spp, Cyperus longus and Setaria sp were sampled and analyzed for minerals. Average macro-mineral concentrations of calcium, phosphorus, magnesium, sodium, potassium, chorine, sulfur and micro-minerals of iron, copper, manganese, molybdenum, cobalt and selenium were 17.37, 0.78, 6.85, 15.40, 3.13, 14.22, 9.49 g/kg and 820.2, 20.0, 72.8, 93.2, 0.43, 0.21 and 0.18 mg/kg for sampling sites and 12.14, 0.77, 6.35, 17.85, 3.59, 14.40, 5.01 g/kg and 1106.0, 18.5, 64.8, 122.4, 0.32, 0.19, and 0.16 mg/kg for forage species, respectively. Comparison of the plant minerals with Sistani cattle mineral requirements showed that Sistani cattle grazing natural indigenous forages was exposed to phosphorus deficiency and iron excess.

Published: December 2022

Background: Tianhuang formula (THF) is a Chinese medicine prescription that is patented and clinically approved, has been shown to improve energy metabolism, but the underlying mechanism remains poorly understood. The purpose of this study is to clarify the potential mechanisms of THF in the treatment of type 2 diabetes mellitus (T2DM).
Methods: A murine model of T2DM was induced by high-fat diet (HFD) feeding combined with low-dose streptozocin (STZ) injections, and the diabetic mice were treated with THF by gavaging for consecutive 10 weeks. Fasting blood glucose (FBG), serum insulin, blood lipid, mitochondrial Ca2+ (mCa2+) levels, mitochondrial membrane potential (MMP) as well as ATP production were analyzed. The target genes and proteins expression of visceral adipose tissue (VAT) was tested by RT-PCR and western blot, respectively. The underlying mechanism of the regulating energy metabolism effect of THF was further explored in insulin resistance model of 3T3-L1 adipocytes cultured with dexamethasone (DXM).
Results: THF restored impaired glucose tolerance and insulin resistance in diabetic mice. Serum levels of lipids were significantly decreased, as well as fasting blood glucose and insulin in THF-treated mice. THF regulated mCa2+ uptake, increased MMP and ATP content in VAT. THF increased the mRNA and protein expression of AMPK, phosphorylated AMPK (p-AMPK), MICU1, sirtuin1 (SIRT1) and peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α). THF could increase the mCa2+ level of 3T3-L1 adipocytes and regulate mitochondrial function. The protein expression of AMPK, p-AMPK, mCa2+ uniporter (MCU) and MICU1 decreased upon adding AMPK inhibitor compound C to 3T3-L1 adipocytes and the protein expression of MCU and MICU1 decreased upon adding the MCU inhibitor ruthenium red.
Conclusions: These results demonstrated that THF ameliorated glucose and lipid metabolism disorders in T2DM mice through improvement of AMPK/MICU1 pathway-dependent mitochondrial function in adipose tissue.

Viewing angle control for automotive display using hybrid nematic liquid crystals
Authors: Oh seungwon , Lee jaehwan , An chanheon , Lee giho
Published: December 2022

As many displays are installed inside electric vehicles, technologies for controlling the viewing angles are attraction. We demonstrate a viewing-angle controllable device comprising hybrid-aligned nematic (HAN) liquid crystals. In the narrow viewing mode, the optical axis distribution in the HAN cell changes from hybrid to twist by changing the viewing angle from normal to oblique. The proposed HAN cell can be switched to wide viewing mode by applying a vertical electric field. Therefore, the switchable viewing-angle-controllable device can control the driver's viewing angle and block the reflected light from the co-driver's window. The proposed mechanism can be further applied to construct an achromatic polarization rotator with angle-dependence.

Published: December 2022

Background Adolescents and young adults are a diverse patient population with unique healthcare needs including sensitive and confidential services. Many clinics serving this population began offering telemedicine during the Covid-19 pandemic. Little is known regarding patient and parent experiences accessing these services via telemedicine. Methods To assess for trends and disparities in telemedicine utilization in the first year of the pandemic, we used the electronic health record to obtain patient demographic data from an adolescent and young adult medicine clinic in a large urban academic institution. Characteristics of patients who had accessed telemedicine were compared to those who were only seen in person. Mean age was compared using t-test, while other demographic variables were compared using chi-squared test or Fisher’s exact test. We performed qualitative semi-structured interviews with patients and parents of patients in order to characterize their experiences and preferences related to accessing adolescent medicine services via telemedicine compared to in-person care. Results Patients that identified as female, white race, Hispanic/Latinx ethnicity were more likely to have utilized telemedicine. Telemedicine use was also more prevalent among patients who were privately insured and who live farther from the clinic. Although interview participants acknowledged the convenience of telemedicine and its ability to improve access to care for people with geographic or transportation barriers, many expressed preferences for in-person visits. This was based on desire for face-to-face interactions with their providers, and perception of decreased patient and parent engagement in telemedicine visits compared to in-person visits. Participants also expressed concern that telemedicine does not afford as much confidentiality for patients. Conclusions More work is needed to address patient and parent preferences for telemedicine as an adjunct modality to in-person adolescent and young adult medicine services. Optimizing quality and access to telemedicine for this patient population can improve overall healthcare for this patient population.

Authors: Ahmad Muntaser S. , Alkhatib Sanaa G. , Mohammad Hjouj
Published: December 2022

The importance of the study is in using computed tomography (CT) to measure the size and dimensions of the liver as well as in its discovery of a mathematical technique to attain and increase the accuracy in the calculation of liver’s size and dimensions. The study was based on 603 individuals who underwent an abdominal CT scan in Hebron-Palestine. The IntelliSpase Portal 9 (Philips) was used to measure the liver’s six dimensions, including transverse, vertical, and anteroposterior dimensions of the right and left lobes. Mathematical equations based on the liver shape were used to calculate the size of the liver. Ultimately, a comparison of the developed and standard formulae’ for the diagnosis of hepatomegaly was carried out. Based on these findings, four hepatic forms were identified and calculations were conducted. The results showed that the Area under Curve (AUC) in the total sample was 0.92, and for the I-IV liver types was 0.87–0.93. The specificity of diagnosing hepatomegaly calculated using general formula was 87%, which practically does not differ from the values of this indicator with a differentiated approach: Type I − 91%, Type II- 84%, Type III- 86%, and Type IV- 90%. In conclusion, the standard formula for determining liver can be utilized in clinical practice: V = (HRL + TRL)3/21, (V – volume, HRL – high of right lobe, TRL – thickness of right lobe).
