An Overview of High-Rise Buildings in Jakarta since 1967 to 2020

High-rise buildings in big cities are crucial for business, economic, educational, residential, and entertainment activities in recent times. The technology discoveries in various fields that support high-rise building construction such as structure, mechanical, electrical, and materials have opened up opportunities for comfortable and environmentally safe architectural work. The first milestone of high-rise building construction knowledge in Indonesia was the completion of the thirteen-floors Sarinah retail building in 1967. Indonesia, especially in Jakarta, then experienced rapid growth of high-rise buildings construction. However, there is limited research on the development of high-rise building designs in Indonesia, especially from an architectural design perspective. It leads to the lack of literature on high-rise building design in Indonesia. By utilizing a publicly accessible database from the Council of Tall Buildings and Urban Habitat and recent literature called Designing Tall Building by Mark Sarkisian, this paper explores the design development of high-rise buildings in Jakarta from time to time in the aspects of architecture, structure and sustainability.
On the mechanism of promiscuous ligand-binding by multidrug resistance regulator LmrR and structural investigations of lytic transglycosylase MltF

Het eiwit LmrR (Lactococcal multidrug resistance Regulator) wordt gemaakt door Lactococcus lactis en is voor deze bacterie noodzakelijk om te kunnen overleven in de aanwezigheid van bepaalde cytotoxische verbindingen, zoals ethidium en daunomycine. LmrR is een DNA transcriptie-regulator, die, via herkenning en binding van de structureel zeer verschillende giftige stoffen, zorgt voor een verhoogde productie van het transporteiwit LmrCD, Dit transporteiwit zit in het celmembraan en zorgt voor actieve uitscheiding van de giftige stoffen, alvorens deze in de cel hun bestemming kunnen bereiken. In dit proefschrift worden kristalstructuren van LmrR gepresenteerd, in ongebonden toestand, alsmede in binding met verschillende antibiotica. Analyse van deze structuren heeft geleid tot de onthulling van de belangrijkste structurele elementen die nodig zijn voor de herkenning en binding van de structureel verschillende antibiotica (het multidrug-bindingsmechanisme). LmrR heeft een karakteristieke “β-wing helix-turn-helix” opvouwing,, met daarnaast nog een extra helix aan de C-terminus die betrokken is bij de dimerisatie van het eiwit. De dimere vorm van het eiwit is erg ongebruikelijk, vanwege een grote hydrofobe porie die dwars door het midden van het dimeer loopt en die de bindingsplaats bevat voor de verschillende antibiotica. De vlakke lipofilische antibiotica binden op een vergelijkbare manier met hun aromatische groepen gesandwicht tussen de indool groepen van twee dimeer-gerelateerde tryptofanen. Het gebruik van een gemeenschappelijke bindingsplaats voor multidrug-binding, in plaats van een grote bindingsplaats bestaande uit deels overlappende specifieke subbindingsplaatsen, alsmede de belangrijke rol voor de tryptofanen bij herkenning en binding van de antibiotica, onderscheiden LmrR duidelijk van andere bekende multidrug-bindinde transcriptiefactoren.
Environmental Assessment of Relationships and Mutual Influences in the System “Protective Forest Plantations – Anthropogenic Landscapes”

Protective forest plantations (PFP) play an essential functional role in the operation of anthropogenic landscapes (AL). A study of processes in the system “PFP-AL” was conducted in the Boguslav agroforestry state, Kyiv region, Ukraine, to maintain sustainability. A method of ecological monitoring has been proposed to achieve environmental equilibrium stability. The calculations show the stable state of the ecosystem. A graphic-analytical method for quantitative assessment of the potential adverse effects of natural resource management has been proposed. It is shown that additional compensation of adverse effects is necessary, which can be performed by green structures.
Numerical simulation of a plasmonic lens for laser light focusing

In this paper, the design of a plasmonic lens in gold and silver thin films for focusing the light with radial polarization is presented. Using the finite difference time domain method the optimal parameters of the plasmonic lens design are found. It was shown that the silver plasmonic lens produces a tight focal spot with a full width at half maximum of 0.38 of the incident light wavelength.
A Spatiotemporal Analysis of Water Quality and Land Use in Tambayakbayan River, Yogyakarta

The Special Region of Yogyakarta is one of the areas that experienced a fairly high population growth rate and is directly proportional to the rate of development which has an impact on land use, especially in Tambakbayan watershed. This study aims to identify the types of land use that affected water quality of the Tambakbayan River using spatiotemporal analysis and Pearson correlation methods. Land use in Tambakbayan watershed is divided into three segments which are vegetation (VA), agriculture (AG), and building (BU). This study used water quality data from the Environmental Agency of Yogyakarta Province which consists of 14 parameters, i.e., pH, TDS, TSS, DO, BOD, COD, nitrate, nitrite, total phosphate, Zn, Cu, Pb, E. coli, and total coli. Landsat 8 image data from 2013 to 2020 is used from USGS. The result of this study found that vegetation has no correlation on Tambakbayan River water quality. However, agriculture and building areas significantly affected the decreasing water quality of the Tambakbayan River.
Screening of Bioactive Metabolites Actinomycetes to Evaluate Potential Sources of Sustainable Marine Natural Products

This study aimed to screen the activity of methanol extract of sponge-derived actinomycetes as an anti-biofilm and antibacterial agent to Staphylococcus aureus. Nine actinomycetes isolates were selected from the UPT LTSIT deposit. S. aureus was obtained from the skin of patients at Abdul Moeloek General Hospital. An antibiotic susceptibility test was performed by the disk diffusion method. Biofilm formation of S. aureus was tested using the crystal violet method. The viability of pathogenic bacteria was measured using the indicator resazurin. The results of the biofilm formation test in vitro revealed that the organic extracts 33A1T2, 33A2T3, 21A1T11, and 38A1T12 inhibited bacterial growth at 0.5 mg/mL. Meanwhile, 50A2T9, 21A1T11, and 38A1T12 significantly inhibited the formation of staphylococcal biofilm on polystyrene at a concentration of 0.25 mg/mL. This information is very important as a basis for further understanding of the mechanism of action of antibiofilm agents.
TIME ACCURATE EULER SIMULATION OF INTERACTION OF NOZZLE WAKE AND SECONDARY FLOW WITH ROTOR BLADE IN AN AXIAL TURBINE STAGE USING NONREFLECTING BOUNDARY CONDITIONS

The objective of this paper is to investigate the three dimensional unsteady flow interactions in a turbomachine stage. A three-dimensional time accurate Euler code has been developed using an explicit four-stage Runge-Kutta scheme. Three-dimensional unsteady non-reflecting boundary conditions are formulated at the inlet and at the outlet of the computational domain to remove the spurious numerical reflections. The three-dimensional code is first validated for 2-D and 3-D cascades with harmonic vortical inlet distortions. The effectiveness of non reflecting boundary conditions is demonstrated. The unsteady Euler solver is then used to simulate the propagation of nozzle wake and secondary flow through rotor and the resulting unsteady pressure field in an axial turbine stage. The three dimensional and time dependent propagation of nozzle wakes in the rotor blade row and the effects of nozzle secondary flow on the rotor unsteady surface pressure and passage flow field are studied. It was found that the unsteady flow field in the rotor is highly three-dimensional and the nozzle secondary flow has significant contribution to the unsteady pressure on the blade surfaces. Even though the steady flow at the midspan is nearly two-dimensional, the unsteady flow is 3-D and the unsteady pressure distribution can not by predicted by a 2-D analysis.Copyright © 1995 by ASME
Effects of mindfulness-based stress reduction on negative emotions and sleep quality levels of clinical medical staff members

Objective: The aim of the current study was to explore the effects of mindfulness-based stress reduction (MBSR) on negative emotions and sleep quality levels of clinical medical staff members. Methods: A total of 100 clinical medical staff members were randomly divided into the study group and control group. Both groups were given psychological care in the hospital. Only the study group received MBSR, performed once a week on Wednesday for 2 hours, for a total of 8 weeks. Self-Rating Depression Scale (SDS), Self-Rating Anxiety Scale (SAS), Five Facet Mindfulness Questionnaire (FFMQ), and Self-Rating Scale of Sleep (SRSS) scores were evaluated before the study and at week 4 and week 8, respectively. Results: After 4 and 8 weeks of intervention, SDS, SAS, and SRSS scores of the study group were significantly lower than those of the control group (P<0.05). FFMQ scores were significantly higher than those of the control group (P<0.05). Moreover, intervention effects were more significant over time (P<0.05). Conclusion: Mindfulness-based stress reduction can significantly reduce negative emotions, improve sleep quality levels of clinical medical staff members, and contribute to overall psychological and sleep health. Therefore, MBSR is worthy of further clinical application.
HEMOCOMPATIBILITY OF SURFACE MODIFIED SILK FIBROIN MATERIALS : A REVIEW

Hemocompatibility test is very common and important during development of biomaterials in direct contact with blood. Moreover, silk fibroin based biomaterials have been used in biomedical application for more than one hundred years and increasing sharply. Recent reports from our group and others have demonstrated that it has acceptable mechanical properties and patency rates in animal models. Unfortunately, pure silk fibroin shows poor hemocompatibility. Thus, the surface of a silk fibroin should be modified to improve its blood compatibility when it is used as a blood-contacting material especially for small diameter arterial prostheses. Researchers have studied hemocompatibility of silk fibroin biomaterials; however, the testing procedures vary greatly throughout different publication. Thus it is not easy to get the exact information from the literatures to performing hemocompatibility assays. Therefore, this paper reviews the studies on effects of surface modification on hemocompatibility in terms of hemolysis, anticoagulation, platelets adhesion, plasma recalcification time (PRT), activated partial thromboplastin time (APTT) and plasma prothrombin time (PT) assays of silk fibroin biomaterials. At last, other physical and biological tests which are also essential and related to the hemocompatibility testing, were also discussed in this paper.
Bankruptcy Risk Premium and the Valuation of Stock Options

This study develops a model under the equilibrium framework to value stock options subject to bankruptcy risk, to introduce the bankruptcy risk premium, and to analyze the term structure of bankruptcy probability. We offer a closed-form solution for the option prices, which is related to the magnitude of bankruptcy risk premium and the term structure of risk-neutral bankruptcy probability. The empirical results show that bankruptcy risk premiums are significant before bankruptcy events, and that specifying a short-run credit risk factor can fit the market implied-volatility better than the traditional jump-to-default model does.

Active Gurney Flaps: Their Application in a Rotor Blade Centrifugal Field

Miniature trailing-edge effectors are segmented gurney flaps that can deploy to achieve multipurpose functions, such as performance enhancement, noise/vibration control, and/or load control on rotor blades. The unsteady aerodynamics of miniature trailing-edge effectors and a deployable plain flap (with an equivalent lift gain) are quantified experimentally at a reduced frequency of 0.21 and a Reynolds number of 1×106. These experiments are also simulated using computational fluid dynamics. The combination of the wind tunnel experiments and computational fluid dynamics are used to quantify the aerodynamic effects of miniature trailing-edge effector deployment to compare their unsteady aerodynamics to plain flaps, and to evaluate the fluid dynamics of miniature trailing-edge effectors against experimental data. The current experiments display unsteady aerodynamics that corroborate previous computational fluid dynamics findings that indicate that miniature trailing-edge effectors shed on-surface vortices dur.
FOREIGN BANK S IN CENTR AL AND EASTERN EUROPE: THE GOOD, THE BAD AND THE UGLY*

1 Foreign banks have played a major role in Central and Eastern European economic landscape over the last decades. They have spurred banking intermediation and fuelled economic growth for years. However, the global financial crisis unveiled the other side of the coin. This article analyses foreign banks’ lending behaviour in Central and Eastern Europe over the period from 2000 to 2016. It aims to investigate the nexus between bank loan growth, cross-border bank claims and the cycle period. Moreover, it captures the impact of the financial cycle on foreign banks’ credit behaviour and highlights whether foreign bank ownership is influenced by hostand home-country effects. Our findings reveal the strong nexus between foreign banks’ loan growth and cross-border bank claims. Also, we emphasize the pro-cyclicality of foreign banks’ loan growth and cross-border bank claims. Furthermore, we see clear differences related to foreign banks’ lending behaviour during normal and turbulent times, triggered by hostand home-country effects. These results raise policy challenges regarding the right bank ownership balance and the use of prudential regulation.
Gas-phase Modeling of the Cometary Coma of Interstellar Comet 2I/Borisov

Comet 2I/Borisov is the first interstellar comet observed in the solar system, providing a unique opportunity to understand the physical conditions that prevailed in a distant unknown planetary system. Observations of the comet show that the CO/H2O ratio is higher than that observed in solar system comets at a heliocentric distance r h < 2.5 au. We aim to study the gas-phase coma of comet 2I/Borisov using a multifluid chemical-hydrodynamical model. The gas-phase model includes a host of chemical reactions, with the neutrals, ions, and electrons treated as three separate fluids. Energy exchange between the three fluids due to elastic and inelastic scattering and radiative losses are also considered. Our model results show that in the region of the coma beyond ∼100 km of the nucleus, e−−CO inelastic collisions leading to vibrational excitation of CO causes a loss of energy from the electron fluid. We find a high abundance of CO+ and HCO+ ions, and we show how these two ions affect the creation/destruction rates of other ions such as H2O+, H3O+, N-bearing ions, and large organic ions. We find that the presence of CO leads to a higher abundance of large organic ions and neutrals such as CH3OH2+ , CH3OCH4+ , and CH3OCH3, as compared to a typical H2O-rich solar system comet. We conclude that the presence of a large amount of CO in the coma of comet 2I/Borisov, combined with a low production rate, affects the coma temperature profile and flux of major ionic species significantly.

An adaptive optimisation scheme for controlling air flow process with satisfactory transient performance

A non-identifier-based adaptive PI controller is designed using a gradient approach to improve the performance of a control system when device aging and environmental factors degrade the efficiency of the process. The design approach is based on the model reference adaptive control technique. The controller drives the difference (error) between the process response and desired model output to zero asymptotically at a rate constrained by the desired characteristics of the model. The tuning rules are designed and justified for a non-linear process with dominant dynamics of second order. The advantage of this method for tracking and regulation compared to adaptive MIT control was validated in real time by conducting experiments on a laboratory air flow control system using the dSPACE interface in the SIMULINK software. The experimental results show that the process with adaptive PI controller has better dynamic performance and robustness than that with traditional adaptive MIT controller.

The Procedure of Praxeological Economics and Its Relation to “Positive Economics”

This essay combines two ideas: (1) a praxeological view of the definition of the subject matter of economics (praxeological economics) and (2) the goal of evaluating arguments for and against market intervention on the basis of logic and relevance. Pursuing this goal and using the praxeological view has three important properties. First, it accounts at the most fundamental level for the fact that human actors are distinct from other animals and robots. Second, it satisfies the traditional goal in political economy to evaluate arguments for or against intervention in a market economy. Third, it is value free. Moreover, this combination implies a general procedure for evaluating interventionist arguments. The essay describes this procedure in four steps. Afterwards it uses the knowledge that is gained from deriving the procedure to assess some of the propositions that economists associate with the idea of positive economics. Five propositions are assessed.
Improving Integrated STEM Education: The Design and Development of a K-12 STEM Observation Protocol (STEM-OP) (RTP)

Dr. Emily Dare is an Assistant Professor of Science Education at Florida International University. Dr. Dare’s research interests focus on K-12 STEM education. In particular, she is interested in supporting science teachers’ pedagogy while also exploring their beliefs about teaching and learning. As science classrooms shift towards integrated STEM approaches that include engineering design as a central component, this is especially critical. Additionally, Dr. Dare has a passion for working with K-12 students to understand how changes in classroom instruction towards these integrated STEM approaches impact their attitudes towards and beliefs about STEM fields. In particular, she examines methods that positively impact girls, which may increase the number of women pursuing careers in STEM-related fields where they are currently underrepresented.
EMG feature evaluation for movement control of upper extremity prostheses

A variety of EMG features have been evaluated for control of myoelectric upper extremity prostheses. Movement class discrimination, robustness, and computational complexity of these features have been investigated for different time window sizes and noise levels. The measurements include novel application of the Davies-Bouldin index, a measure of cluster separability, and the K-nearest neighbor nonparametric classifier. The features evaluated are the integral of average value, the variance, the number of zero crossings, the Willison amplitude, the v-order and log detectors, and autoregressive model parameters. A new feature, the EMG Histogram, is introduced and shown to be the most effective of the group. The experiments were done on the data acquired from the residual biceps and triceps muscle of an above-elbow amputee.
A new approach for the design of digital integrators

A new method is proposed for the design of digital integrators. The new method is based upon the formulation of an appropriate linear programming problem which assures a satisfactory minimax approximation error for the magnitude response in a predefined frequency range. In comparison with existing methods the new design approach constructs a novel class of digital integrators by optimal determining more than one independent coefficients. Their capability to approximate in the minimax sense the ideal integrator with a good accuracy is shown. Well-known integrators can be obtained as special cases of the proposed methodology. Appropriate constraints can be introduced to accommodate signals with low frequencies.
