ABSTRACTBatam is the largest city in the Riau Islands Province with a population predicted to reach 1.8 million people in 2025. This study aims to determine the capacity of the Duriangkang Reservoir and Mukakuning Reservoir to meet the current and future water needs. The data used are: rainfall data from Hang Nadim Meteorological Station from 2011 to 2020, topographical maps and geometric data of the two reservoirs. In this study the author uses the ripple method. Although previously have been analyzed using several methods, it is possible that there are still differences between the design and the reality on the ground. The results will determine the reliability and volume in the two reservoirs. There were no failures in 2019 and there were 2 failures occurred in 2020 in the Duriangkang Reservoir. Meanwhile, for Mukakuning Reservoir, there were 2 failures that occurred in 2019 and 4 failures in 2020. Based on the ability of the water treatment plant to serve the water needs, Duriangkang reservoir can serve raw water needs in 2020 & 2025, but in 2030 with the water demands hit 3914,6353 L/s Duriangkang Reservoir cannot be fulfilled. For Mukakuning Reservoir, water needs in present & future cannot be fulfilled.Keywords: Reservoir Storage Capacity, Ripple Method, Reservoir reliability, water needs, rainfall dataABSTRAKKota Batam merupakan kota terbesar di Provinsi Kepulauan Riau dengan jumlah populasi di prediksi mencapai 1,8 juta jiwa pada tahun 2025.

ANALISA PUSHOVER PADA STRUKTUR BETON DENGAN EXTERNAL PRESTRESSING UNTUK TRANSFER GAYA AKSIAL
Authors: Felix Christopher
Published: December 2022

Penambahan jumlah lantai pada bangunan eksisting akibat perubahan fungsi bangunan akan berpengaruh pada beban dipikul oleh pondasi yang sudah ada. Sehingga perencana bangunan tersebut harus melakukan pengecekan ulang pengaruh penambahan beban tersebut terhadap bangunan eksisting. Penambahan jumlah tiang pondasi tidak mungkin dilakukan sehingga perlu dilakukan pemindahan gaya aksial pada kolom. Pemindahan gaya dapat dilakukan dengan menaikan kekakuan kolom. Namun untuk memindahkan gaya aksial kolom yang cukup besar perlu dilakukan dengan menggunakan prategang external. Bangunan yang digunakan untuk studi kasus adalah bangunan eksisting 3 dimensi yang didesain dengan standar penulangan SK SNI T-15-1991-03 dan tahan gempa dengan standar SNI 1726-2002. Gaya aksial kolom tepi dipindahkan ke kolom sudut dengan tendon Strand baja mutu 270 Ksi (1860 MPa) ukuran 12.7 mm dengan standar ASTM A416 dan didesain dengan kombinasi beban tegangan izin (ASD). Dalam pengujian analitis digunakan 4 jenis model dengan gaya jacking yang sama namun jumlah tendon dan ukuran strand berbeda-beda. Bangunan dengan prategang tersebut akan ditinjau pengaruhnya terhadap gempa SNI 1726-2019 dengan metode pushover Analysis. Penggunaan external prestressing menghasilkan nilai faktor reduksi gempa (Ry1) dan waktu getar efektif (Te) yang lebih kecil dibandingkan dengan eksisting. Selain memindahkan gaya, External Prestressed juga memberikan sumbangan kekakuan pada bangunan eksisting.

Authors: Giang Vu Thi Thu , Hue Pham Thi Minh , Trang Nguyen Hong
Published: December 2022

Quercetin is a well-known flavonoid with different biological effects such as anti-inflammatory, antioxidant, etc. However, this active ingredient was not applied broadly in clinical treatment due to the limitation of solubility, stability, and low oral bioavailability. To overcome this limitation, phytosome quercetin was prepared to enhance quercetin's physicochemical properties and permeability. In the study, prepared phytosome complexes were applied in capsules and evaluated hepatoprotective activity. The study found the optimal formula of capsules containing quercetin phytosome with the active ingredient content of 50 mg that dissolved over 90% of quercetin after 45 minutes. The results of the evaluation of the hepatoprotective activity of the prepared capsules in mice also initially demonstrated that the quercetin phytosome capsules had superior hepatoprotection compared to those containing free quercetin.

Nonlinear Dynamic Inversion with Actuator Dynamics: An Incremental Control Perspective
Authors: Steffensen Rasmus , Steinert Agnes , Smeur Ewoud J. J.
Published: December 2022

In this paper, we derive a sensor-based nonlinear dynamic inversion (NDI) control law for a nonlinear system with first-order linear actuators, and compare it to incremental nonlinear dynamic inversion (INDI), which has gained popularity in recent years. It is shown that, for first-order actuator dynamics, INDI approximates the corresponding NDI control law arbitrarily well under the condition of sufficiently fast actuators. If the actuator bandwidth is low compared to changes in the states, the derived NDI control law has the following advantages compared to INDI: 1) compensation of state derivative terms, 2) well-defined error dynamics, and 3) exact tracking of a reference model, independent of error controller gains in nominal conditions. The comparison of the INDI control law with the well-established control design method NDI adds to the understanding of incremental control. It is additionally shown how to quantify the deficiency of the INDI control law with respect to the exact NDI law for actuators with finite bandwidth. The results are confirmed through simulation results of the roll motion of a fixed-wing aircraft.
Wall-Modeled Large-Eddy Simulation with Second-Order-Accurate Upwind Scheme
Authors: Yasuda Hidemasa , Kawai Soshi
Published: December 2022

In aircraft aerodynamic design, it is essential for certification by analysis to estimate aircraft aerodynamic characteristics with high fidelity across the full flight envelope using computational fluid dynamics. Improving accuracy of the simulation of unsteady flows such as transonic buffet is one of the problems. Wall-modeled large-eddy simulation (WMLES) is expected to improve the accuracy. In this study, three quantitative requirements for the matching points, where LES feeds the wall model with flow variables, are proposed to ensure the accuracy of the WMLES with a second-order-accurate upwind scheme that is often used for engineering codes. These requirements are related to 1) matching point height, 2) the number of cells below the matching point, and 3) grid resolution at the matching point. The proposed requirements are assessed on a flat-plate turbulent boundary layer and a shock/turbulent boundary-layer interaction flow. As a result, it is clarified that all of the requirements are necessary to ensure the accuracy in terms of mean velocity, Reynolds stresses, and skin friction.
Enhanced Adaptive Kriging Method for Estimating Fuzzy Failure Probability with Profust Model
Authors: Yun Wanying , Lu Zhenzhou , Li Luyi
Published: December 2022

Aiming at analyzing the structural fuzzy failure probability with probability inputs and fuzzy-state assumption (profust model), an adaptive kriging model-based sequentially truncated Monte Carlo simulation (MCS) method is investigated, where estimating the fuzzy failure probability can be transformed into identifying the absolute safety domain, the absolute failure domain, and the exact performance function values of the fuzzy safety–failure transition domain. To this end, in this study, three kriging models are sequentially constructed to realize the three aims, respectively. To further improve the efficiency of adaptively updating kriging model, adaptive radial-based importance sampling technique is embedded to divide the whole MCS candidate sampling pool (CSP) into several sub-CSPs. Then, the kriging model is updated sequentially in each sub-CSP instead of the whole CSP, and the samples dropped into the optimal hypersphere of the absolute safety domain can be truncated and do not participate in the CSP of updating the kriging model so that the size of whole MCS CSP and the size of CSP in each learning process of updating kriging are reduced simultaneously. As a result, the efficiency of estimating the fuzzy failure probability is enhanced. The results of two examples verify the effectiveness of the proposed method.

Authors: Maslov A. A. , Starov A. V. , Tsyryulnikov I. S.
Published: December 2022

Methods for restoring aerodynamic forces based on the use of measurement data by balance elements and an accelerometer have been expanded. A signal processing method has been developed that makes it possible to correct the measurement data of balance elements using additional data on the acceleration of support elements. Examples of the application of the proposed method under the conditions of a pulsed wind tunnel in experiments on massive models, both with constant and decreasing flow parameters during the test, are given. An increase in the measurement accuracy of single-component force-measuring sensors is shown.

Objetivo: Comparar resultados entre as técnicas de Bypass e Sleeve em relação ao peso, Índice de Massa Corporal (IMC), circunferência abdominal, resolutividade de hipertensão, diabetes e complicações no pós-operatório. Métodos: Trata-se de um estudo observacional, transversal, descritivo e analítico, seleção por amostra de conveniência de 20 pacientes atendidos em hospital de referência da região amazônica submetidos a uma das duas técnicas estudadas. Utilizou-se banco de dados do hospital, analisando o momento pré e pós-operatório após 1 ano. Resultados: Evidenciou-se relevância estatística de ambas as técnicas na perda de peso, diminuição de IMC, circunferência abdominal, pressão arterial e glicemia em jejum. Contudo, não houve diferença estatística relevante na comparação do impacto positivo das duas técnicas entre os parâmetros citados. Sobre valores absolutos, a perda de peso por Bypass foi mais efetiva, sendo o único parâmetro a apresentar diferença. Conclusão: Ambas as técnicas impactam positivamente na qualidade de vida e no tratamento da obesidade. Na literatura e no presente trabalho, a perda de peso e controle das comorbidades em 1 ano de pós-operatório não evidenciou diferença entre as técnicas, todavia, a longo prazo, o Bypass obteve maior significância. Muitos trabalhos ainda apresentam grande variabilidade de amostra, demonstrando a necessidade da realização de novas pesquisas elucidando melhor do assunto.

Published: December 2022

Involuntary urination (IU) is recognized as a significant health problem. Urinary tract infection (UTI) can increase the risk of involuntary urination. Females are especially prone to UTIs for anatomical reasons. This study investigated the role of microbes in women suffering from UTIs and identified the causative bacteria and explored their antimicrobial resistance patterns that are of epidemiological importance regarding the spread of multi-drug resistance in Saudi Arabia. The study was conducted for a period of one year from September 2020 to August 2021. A total of 1027 midstream urine samples were collected in sterile containers from pregnant women of varied gestational ages attending antenatal clinics. Each sample was divided into two parts for urine analysis and microbial culture. It was found that the most effective antibiotic for the treatment of UTIs is norfloxacin (NOR) which was found to be 100% effective against all the bacterial isolates involved in UTIs. The second most effective antibiotic was found to be ofloxacin (Of) and proven as the effective antibiotic against the bacteria. The antibiotics amikacin (AMK), nitrofurantion (NI) and ampicillin (AMP) were found to be least effective for all UTI-causing bacteria. The singly isolated fungal species Candida albicans displayed sensitivity towards fluconazole.
Identification of potential molecular players and therapeutic drug molecules in Melphalan resistant Multiple myeloma by integrated bioinformatics analysis
Authors: Ghosal Somnath , Banerjee Subrata
Published: December 2022

Multiple myeloma (MM), second most common haematological malignancy, still remains incurable with the acquiring of drug resistance. Melphalan therapy which has been used as one of the key therapies against MM, is impeded by the occurrence of Melphalan resistance. The precise underlying mechanism of this acquired Melphalan resistance in MM is not yet well deciphered. Therefore, this present study was aimed to identify the differentially expressed genes (DEGs) associated micro RNAs (miRNAs) and transcription factors (TFs) from the microarray dataset of Melphalan resistant and Melphalan sensitive MM cell lines, obtained from Gene Expression Omnibus (GEO) database. DEGs were analysed using GEO2R tool from the dataset. Then the gene ontology (GO) and pathway enrichment analysis were executed by using DAVID database. Protein-protein interaction (PPI) network of DEGs was constructed and analysed by using STRING database and Cytoscape tool. Genetic alterations in DEGs were studied through COSMIC database. Network of interaction of DEGs and miRNAs as well as TFs was constructed and analysed by using mirDIP, TRRUST and miRNet tools. Drug gene interaction was examined to identify potential drug molecules by DGIdb tool. Various DEGs that might play pivotal role in Melphalan resistant MM, were detected and selected for further analysis. miRNA analysis detected hsa-mir- 21-3p, hsa-mir-27a-5p, hsa-mir-129-2-3p that could interact with maximum target DEGs. One TF, STAT1 was found to regulate the expression of selected DEGs. The whole study may give a better understanding about the Melphalan resistance in MM.

Published: December 2022

In Oman, palm wastes are estimated at thousands of tons per year. Imagine that this huge amount of waste can be used as an alternative to energy or as a fuel. This project shows the possibility of obtaining cellulose from waste palm trees to protect Oman from the environmental damage caused by burning these wastes. The result obtained from the first experiment was that 80g of raw material gave about 2.5 – 3g of cellulose. In the second experiment, 3.3g of raw material gave about 1.8 – 1.9g of cellulose, while in the third experiment, 4g of the same raw material of the second experiment gave about 1.5 - 1.6g of cellulose. The final products' FTIR showed the functional groups and compared them with the pure cellulose graph. The biogas was produced at the end of this project by using an anaerobic digester. The total volume of the anaerobic digester has been calculated as 7.2 m3 to do the digestion process.

Authors: Veilumuthu P. , Godwin Christopher J.
Published: December 2022

Streptomyces are well known to produce a large number of diverse compounds. An endophytic actinomycete, Streptomyces sp. VITGV01 was isolated from a farm tomato plant. Isolated actinomycetes are cultured in ISP2 medium supplemented with nystatin (15μg/ml) and nalidixic acid (50μg/ml). A total of 240 actinomycetes were isolated and 77 showed antimicrobial properties. One strain that exhibited a high zone of inhibition on primary screening was selected (VITGV01). The SEM studies revealed filamentous tubular structures with continuous aerial hyphae differentiated into tiny, smooth-surfaced chainlike spores. Based on the 16S rRNA analysis and physiological tests, this isolate was found to be a member of the genus Streptomyces suggesting that it might be a new sp. Maximum biomass production was recorded in media containing 1% sucrose and 1% yeast extract cultured at pH 7.0 for 15 days at 300C. The secondary metabolites were active against Bacillus subtilis (MTCC 2756), Staphylococcus aureus (MTCC 737), Escherichia coli (MTCC 1687) and Klebsiella pneumoniae (MTCC 109). A maximum zone of inhibition was observed against K. pneumoniae (22 mm) and a minimal zone of inhibition against B. subtilis (8 mm). FTIR analysis revealed amine, alkane (C=C) aromatic ring, secondary alcohol and alkyl halide groups. The GCMS data showed twenty different compounds, of which fifteen are antimicrobial.

Authors: Anjum Afreen , Singh Vikram , Adil Smriti , Quraishi Afaque
Published: December 2022

An in vitro propagation protocol has been developed for Curcuma caesia Roxb., an endangered medicinal plant by Foundation for Revitalisation of Local Health Traditions and Central Forest Department of India. The plant bears poorly germinated seeds and produces two-storage organs: rhizomes and multiple root tubers. Only rhizomes have medicinal-economic values. They serve as propagules too, which results in a shortage of planting material. Therefore, a complete one-year production cycle of C. caesia has been standardized through in vitro propagation including explants establishment (one month), subculture cycles (seven months), rooting (one month) followed by primary hardening (one month) and secondary hardening (two months). Dormant shoot buds on rhizome served as explants for culture initiation on Murashige and Skoog (MS) medium supplemented with different concentrations of 6-benzyladenine (BA) and kinetin (KIN) in combination with citric acid (CA), adenine sulfate (AdS) and indole- 3-acetic acid (IAA). Maximum bud break (70%) was obtained on MS with 8 mg L-1 BA, 8 mg L-1 KIN, 100 mg L-1 CA, 200 mg L-1 AdS and 2 mg L-1 IAA (standard medium). Shoot production potential continued on this medium during the subsequent seven-month-long subculture cycle. The in vitro raised shoots rooted best on ½-strength MS containing 1 mg L-1 indole-3-butyric acid. Plantlet survival rate was >95% after acclimatization. The genetic homogeneity of plantlets with the mother plant was analyzed using Inter Simple Sequence Repeats which generated a monomorphic banding pattern to confirm the uniformity of in vitro raised plantlets of C. caesia.
Screening of strictocidine synthase and lysine decarboxylase gene involved in alkaloid biosynthesis in plants of Catharanthus rosea, Adathoda vasica and Wedelia trilobata
Authors: Lahare Rajeshwari Prabha
Published: December 2022

Alkaloids are naturally occurring nitrogenous organic compounds of plant and display vast range of pharmacological properties such as anticancer, antiviral, anti-diabetic, antioxidant and antimicrobial activities. Medicinal plants are the main source of secondary metabolites and the enzymatic pathway involved in its production may be enhanced to increase synthesis of metabolites. The strictocidine synthase (STR) and lysine decarboxylase (LDC) gene are involved in biosynthesis of monoterpenoid indole alkaloid and quinolizidine alkaloid respectively. In the present study, STR and LDC gene were analyzed in Catharanthus roseus, Adathoda vasica and Wedelia trilobata using real time PCR. The PCR results showed S shaped curve with Ct value for amplification of target gene which was found in Catharanthus roseus for STR gene and in Catharanthus roseus and Adathoda vasica for LDC gene. For further confirmation of target, gene samples were separated on agarose gel for size determination and the size of STR gene was found to be 1.1 kb and LDC gene was 1.3 kb respectively. Thus this study should be beneficial for academic as well as industrial point of view from production of alkaloids in plants by enhancing STR and LDC gene synthesis and alkaloids should also be used for isolation and characterization for pharmaceutical applications.

Authors: Yusniawati Yustina Ni Putu , Ida Rahmawati  , Lewar Emanuel Ileatan
Published: December 2022

An emergency condition is a situation that requires quick, precise, and appropriate action to save lives. Delays in providing emergency assistance often occur in children, where the result of this delay is permanent disability and even death. Emergency for children is an important concern because children are not used to expressing uncomfortable conditions in an emergency. Emergency conditions that often occur in children are choking and cardiac arrest. The purpose of this study was to determine the difference in maternal knowledge before and after being given counseling about choking, and cardiopulmonary resuscitation. This study uses a Pre-Experiment with One Group Pre-test Post-test design with a cross-sectional approach. The research was conducted in Ubung Kaja Village. The population in this study were 70 parents who had children aged 0-2 years. Univariate analysis was used to determine the demographic data of the respondents. Bivariate analysis was used to determine differences in maternal knowledge before and after being given counseling about choking and CPR. The results showed that (Choking P 0.000 <a = 0.05), and (Cardiac arrest P 0.000 <a = 0.05). There is an effect of providing counseling on mother's knowledge in emergency handling of fever, choking and cardiac arrest. Further training on emergencies needs to be carried out on an ongoing basis because emergencies can happen anywhere.
Sustainable Fertilizers: Current Publication Landscape and Challenges

Published: December 2022

The ability of modern agriculture to meet future food demand imposed by accelerating growth of the world’s population is a major challenge, and fertilizers play a key role by replacing nutrients in agricultural soil. Given the need for fertilizer, its costs in nonrenewable resources and energy, and the consequences of the CO2 emissions required to make it, people have begun to explore ways to make fertilizer manufacture and use more sustainable. Using data from the CAS Content Collection™, this review examines and analyzes the academic and patent literature on sustainable fertilizers from 2001-2021. The breakdown of journal and patent literature publication over time on this topic, country or region of publications, the substances included in published research, among other things, allows us to understand the general progress in the field, as well as the classes of materials and concepts driving innovation. We hope that this bibliometric analysis and literary review will assist researchers in relevant industries to discover and implement ways to supplement conventional fertilizers and nutrient sources while improving the efficiency and sustainability of waste management and ammonia production.
Covalent adduct formation as strategy for efficient CO2 fixation in crotonyl-CoA carboxylases/reductases
Authors: Recabarren Rodrigo , Tinzl Matthias , Saez David , Gomez Aharon , Erb Tobias , Vöhringer-Martinez Esteban
Published: December 2022

Increasing levels of CO2 in the atmosphere have led to a growing interest into the various ways nature transforms this greenhouse gas in valuable organic compounds. Crotonyl-CoA carboxylases/reductases (Ccrs) are the most efficient biocatalysts for CO2 fixation because of their oxygen tolerance, their high catalytic rate constants and their high fidelity. The reaction mechanism involving hydride transfer from the NADPH cofactor and addition of CO2 to the reactive enolate, however, is not completely understood. In this study, we use computer simulations in combination with high-level ab initio calculations to trace the free energy landscape along two possible reaction paths and identify a thermodynamically stable covalent adduct formed between the substrate and the NADPH cofactor in agreement with experimental observation. This C2 adduct serves as a stable intermediate avoiding the reduction side reaction of the reactive enolate species and it is able to react with CO2 with similar kinetics as the direct reaction mechanism as confirmed by measured kinetic isotope effects. Thus, our results show that nature's most efficient CO2-fixing enzyme uses the formation of a covalent adduct as a strategy to store the reactive enolate species. The emerging microscopic picture of the CO2-fixing mechanism confirms previous experimental observations and provides new insights into how nature handles highly reactive intermediates to fix the inert greenhouse gas.

En América Latina: Poder y no-poder de las tecnologías
Authors: Torres Acuña Luis
Published: December 2022

Iniciaremos este texto con una afirmación categórica y central que servirá de base al presente ensayo: plantearse la cuestión política en relación con las mal llamadas Nuevas Tecnologías implica problematizar los aspectos más relevantes y sustanciales de ellas, en términos de la importancia que estas tienen para nuestra sociedad latinoamericana. En suma, las llamadas Nuevas Tecnologías no constituyen entes extraños y ajenos a lo social, que descienden de alguna parte y "permean" la vida social. Más bien ellas están sujetas, de algún modo, a una forma compleja de determinismo causal socio-histórico, que las funda y las explica.

Authors: KORKMAZ Merve , KAPLAN Kaplan
Published: December 2022

Şeker hastalığı insanlarda kan şekeri seviyesinin anormal değerlere ulaştığı kronik bir rahatsızlıktır. Şeker hastalığının erken teşhisi, bu hastalığın sebep olabileceği daha büyük hastalıkların önlenmesi ve gerekli tedavi planlamasının zamanında gerçekleştirilmesi açısından önemlidir. Bu çalışma kapsamında şeker hastalığı çeşitli modeller ile teşhis edilerek, bu problem için kullanılabilecek en uygun model belirlenmeye çalışılmıştır. Çalışmada Lojistik Regresyon, k-En Yakın Komşuluk, CART (Sınıflandırma ve Regresyon Ağacı), Rastgele Orman, Destek Vektör Makinesi, XGBoost ve LightGBM sınıflandırıcı modelleri kullanılmıştır. 10 katlı çapraz doğrulama yöntemi kullanılarak performans ölçütleri elde edilmiştir. Modellerin doğruluk oranları sırası ile %84,58, %84,59, %85,02, %88,29, %84,73, %89,29 ve %88,72 olarak elde edilmiştir. Modeller arasında en iyi üç doğruluk oranını veren Rastgele Orman, XGBoost ve LightGBM yöntemlerinde hiper-parametre ayarlaması gerçekleştirilerek en iyi parametreler belirlenmiştir. Bu parametreler ile final modellerinin doğruluk oranları sırasıyla %89,2998, %90,0141 ve %90,0121 olarak elde edilmiştir. Sonuç olarak XGBoost ve LightGBM modellerinin final teşhis modelleri olarak kullanılabileceği gözlemlenmiştir.

Published: December 2022

Los problemas de salud mental de los y las docentes es una realidad que sin duda es preocupante y que por consiguiente no se puede negar; factores como el agobio, las bajas remuneraciones, el estigma social, los desórdenes en los hábitos diarios por falta de tiempo, entre otros factores, evidentemente repercuten en su salud. El siguiente artículo tiene como objetivo indagar en los indicadores de salud física y mental en docentes de la región del Maule y de Ñuble. Desde un diseño cuantitativo se analizan los resultados obtenidos de dos instrumentos, un cuestionario sobre salud y hábitos de vida, y otro de niveles de estrés y emociones. Las observaciones dan cuenta que la realidad sobre este tema no ha cambiado a través de los años y que, en efecto, no existen instancias efectivas que busquen remediar o reparar esta situación que enfrentan muchos de nuestros docentes.
