Design studios are where design students spend most of their time learning theory and practices. For this reason, thermal comfort conditions in studios are crucial to provide a suitable environment for education. Especially in the post-pandemic period, thermal comfort conditions have become more critical in educational buildings. The present study focuses on the adaptive thermal comfort condition in an architectural design studio in the Mediterranean climate of Izmir/Turkey. The study aims to evaluate the comfort conditions of the students and determine the effect of mask use on thermal sensation in the post-pandemic period. For this purpose, air temperature, relative humidity, and air velocity measurements were collected during the studio hours in the spring semester when the heating and cooling systems were not working. Additionally, a thermal sensation survey was conducted with 42 students. The results showed that the thermal comfort level was within the 90% acceptability limits according to the ASHRAE Standard-55. According to the survey results, the use of masks by the students did not have a significant effect on thermal perception.

The main goal of this paper is to demonstrate the general characteristics of the educational
user-friendly CFD Studio package for CFD teaching. The package was designed for
teaching 2D fluid mechanics and heat transfer process, including conduction, coupled
conduction/convection, natural and forced convection, external and internal flows, among
other phenomena. The finite volume methodology and its related topics can also be taught
using the software. Therefore, general aspects of the three main modules, pre-processor,
solver and post-processor are discussed aiming to show the generality of the tool. These
modules are integrated in the application by a so-called numerical problem project
which guide the student through the steps to obtain the solution. To approximate the
partial differential equations the finite volume approach is employed using a fully-implicit
formulation with the interpolation schemes CDS, UDS and WUDS. Mesh editing and nonorthogonal
boundary-fitted mesh generation, using algebraic interpolation and elliptic
equations, are important features of the package. Coupled heat transfer problems are
handled using the solid-block formulation and the pressure-velocity coupling uses the
SIMPLE and SIMPLEC methods with non-staggered grids. To demonstrate the
capabilities two fluid flow and heat transfer problem projects are presented.

Testo completoAbstract (sommario):
Pipeline hydraulic transportation is an important method for transporting solid materials. An LBM–DEM-based simulation method is established in the Visual Studio platform using the Fortran language, which can model the hydraulic transportation process of coarse particles in a pipeline. To verify the feasibility of this numerical simulation method, we also conduct pipeline hydraulic transportation experiments and find that the simulation results are consistent with the experimental results. This method is used to investigate the motion characteristics of coarse particles in horizontal pipelines under different conditions because of its advantages of clear physical meaning, ability to deal with complex boundary conditions, and suitability for parallel computing. The results show that the bedload motion is the main motion mode of coarse particles in horizontal pipelines. Changes in the pipeline flow velocity and particle diameter can cause some particles to saltate, and the critical pipeline flow velocity of saltation particles has a linear relationship with the particle diameter. During the process of coarse particles changing from the static state to stable state, the velocity curve of coarse particles gradually changes from “C” type to “S” type with the increase of particle diameter. Moreover, there is a linear relationship between the pipeline flow velocity and the stable velocity of coarse particles, while the particle diameter has no significant influence on the stable velocity. This study provides guidance for the development of pipeline hydraulic transportation technology of coarse particles.

Testo completoAbstract (sommario):
This article presents a non-collision trajectory planning algorithm in three-dimensional space based on velocity potential field for robotic manipulators, which can be applied to collision avoidance among serial industrial robots and obstacles, and path optimization in multi-robot collaborative operation. The algorithm is achieved by planning joint velocities of manipulators based on attractive, repulsive, and tangential velocity of velocity potential field. To avoid oscillating at goal point, a saturated function is suggested to the attractive velocity potential field that slows down to the goal progressively. In repulsive velocity potential field, a spring damping system is designed to eliminate the chattering phenomenon near obstacles. Moreover, a fuzzy logic approach is used to optimize the spring damping coefficients for different velocities of manipulators. Different from the usual tangential velocity perpendicular to the repulsive velocity vector for avoiding the local minima problem, an innovative tangential velocity potential field is introduced that is considering the relative position and moving direction of obstacles for minimum avoidance path in three-dimensional space. In addition, a path priority strategy of collision avoidance is taken into account for better performance and higher efficiency when multi-robots cooperation is scheduled. The improvements for local minima and oscillation are verified by simulations in MATLAB. The adaptabilities of the algorithm in different velocities and priority strategies are demonstrated by simulations of two ABB robots in Robot Studio. The method is further implemented in an experimental platform with a SCARA and an ABB robot cooperation around a stationary obstacle and a moving object, and the result shows real time and effectiveness of the algorithms.

Studio quantitativo con Cine-RM contrasto di fase in soggetti normali". Rivista di Neuroradiologia 10, n. 2_suppl (ottobre 1997): 43–45. http://dx.doi.org/10.1177/19714009970100s215.
Testo completoAbstract (sommario):
The aqueductal CSF and superior sagittal sinus (SSS) blood flow were quantified in 9 healthy volunteers using a Phase Contrast Cine MR technique with retrospective cardiac gating and velocity of encoding of 10 and 30 cm/s. All subjects were examined in basal conditions, during hypocapnia determined by sustained hyperventilation and during hypercapnia (>5%) obtained with rebreathing in a plastic bag. In basal conditions, the aqueductal CSF flow area showed a mean increase of 24% synchronous with the cerebral systole, whereas variations of the SSS flow area during the cardiac cycle were negligible (>9%). The mean flow velocity and volume in the SSS were 11.7 cm/s and 236 ml/min. Mean peak systolic and diastolic aqueductal CSF velocity were + 2 cm/s and −2 cm/s. Hypocapnia determined in all but one subjects a decrease of the SSS blood and aqueductal CSF velocities. During hypocapnia a decrease of the aqueductal CSF flow area was also observed. Hypercapnia was associated with a decrease of the SSS flow velocity in 3 subjects and to minor changes in the remaining 6 subjects. Hypercapnia determined an increase (up to 30%) in the peak systolic and diastolic aqueductal CSF flow velocity in 3 subjects, negligible changes in 5 subjects and a decrease of the same parameters in one subject. The aqueductal CSF flow area was decreased in 8 subjects during hypercapnia. Hypocapnia and hypercapnia are relatively simple tests which can be used to modify the intracranial hydrodynamic equilibrium in healthy subjects. Further investigations are however needed before their application to the study of intracranial hydrodynamics in patients with hydrocephalus.

Testo completoAbstract (sommario):
We present a new concept of the thermoelectric structure that generates microwave and terahertz signals when illuminated by femtosecond optical pulses. The structure consists of a series array of capacitively coupled thermocouples. The array acts as a hybrid type microwave transmission line with anomalous dispersion and phase velocity higher than the velocity of light. This allows for adding up the responces from all the thermocouples in phase. The array is easily integrable with microstrip transmission lines. Dispersion curves obtained from both the lumped network scheme and numerical simulations are presented. The connection of the thermocouples is a composite right/left-handed transmission line, which can receive terahertz radiation from the transmission line ports. The radiation of the photon to the surface of the thermocouple structure causes a voltage difference with the bandwidth of terahertz. We examined a lossy composite right/left-handed transmission line to extract the circuit elements. The calculated properties of the design are extracted by employing commercial software package CST STUDIO SUITE.

Testo completoAbstract (sommario):
Dead-reckoning via encoders on wheeled-mobile robots is a simple but inaccurate method to estimate position. The major drawback of encoders is wheel slippage errors that accumulate over time. This problem is often addressed by using additional sensors such as compass, gyroscope, or GPS. This paper details the integration and effectiveness of a relatively low-cost solution using an electronic compass to reduce positioning error on a wheeled tricycle mobile robot. A customised Visual Studio program has been developed to adjust the settings of the electronic compass and integrate it with the Visual Studio based robot control system. The electronic compass heading data is fused with the encoder odometry heading data in three different ways: simple fusion, linear weighted fusion, and Kalman filter fusion. Simple fusion and linear weighted fusion rely on parameters determined from angular acceleration and angular velocity, respectively. The Kalman filter uses variance data for the encoders and electronic compass to determine an optimal heading. Experiments have been conducted in an indoor corridor environment to evaluate and compare the various fusion methods. Position error is successfully reduced and is sufficient to locate the robot within the corridor.

Testo completoAbstract (sommario):
Numerical investigation for unsteady, viscous, incompressible Bingham fluid flow through parallel plates is studied. The upper plate drifts with a constant uniform velocity and the lower plate is stationary. Both plates are studied at different fixed temperatures. To obtain the dimensionless equations, the governing equations for this study have been transformed by usual transformations. The obtained dimensionless equations are solved numerically using the explicit finite difference method (FDM). The studio developer Fortran (SDF) 6.6a and MATLAB R2015a are both used for numerical simulations. The stability criteria have been established and the system is converged for Prandtl number Pr≥0.08 with ΔY=0.05 and Δτ=0.0001 as constants. As a key outcome, the steady-state solutions have been occurred for the dimensionless time τ = 4.00. The influence of parameters on the flow phenomena and on shear stress, including Nusselt number, are explained graphically. Finally, qualitative and quantitative comparison are shown.

Untuk mengatasi kesulitan dalam perkiraan hidrograf banjir pada DAS tak terukur di DTA Waduk Wonogiri, dilakukan penelitian awal penggunaan hidrograf satuan metode GIUH. Evaluasi ketelitian metode ini menggunakan acuan hidrograf satuan terukur pada empat DAS yang dihitung menggunakan metode Collins, dengan mencermati debit puncak, waktu puncak, dan waktu dasar. Hasil penurunan hidrograf satuan GIUH digunakan untuk hitungan hidrograf banjir menggunakan program aplikasi model hujan-aliran yang dibuat menggunakan compiler Visual Studio. Hasil penelitian menunjukkan bahwa program aplikasi dapat digunakan untuk hitungan hidrograf banjir secara cepat dengan memanfaatkan sistem telemetri data hidrologi real time dan online. Debit puncak hidrograf banjir metode GIUH cenderung underestimated, yaitu antara -9,3% sampai dengan -54,9%. Untuk waktu puncak dan waktu dasar tidak ditemukan pola perbedaan yang spesifik, yaitu antara 11,1% sampai dengan +66,7% dan -6,7% sampai dengan +46,15%. Penelitian lebih lanjut perlu dilakukan dengan mengkaji lebih detil faktor orde sungai tertinggi dan rumus empirik dynamic parameter velocity agar diperoleh hidrograf satuan yang lebih akurat.

This research investigates practical methods to improve the efficiency of natural ventilation in residential units of multi-family high-rises without additional areas. Typical studio- and one-bedroom-types of small units were redesigned using: 1) air post, 2) transom window, 3) buffer space with one corridor opening and 4) buffer space with two corridor openings. The simulation study using a CFD program to reveal that the indoor average air velocity coefficient (Cv ) in the best redesigned case (0.46) significantly improves from the base case (0.01). The paper demonstrates an example of application to an actual climate in Bangkok, Thailand. It was found that the proposed redesign using buffer spaces can considerably help upgrade the living conditions of the occupants in terms of both thermal comfort (24 hours vs. 0 hours in the comfort zone per day) and indoor air quality (24 hours vs. 8–17 hours that pass the minimum ventilation requirement per day) in the transitional month of February.

The paper presents the results of numerical simulation and experimental studies of the generation of two ribbon beams in an accelerating diode with magnetic insulation at a diode voltage of ~ 0.7 MeV and a current of 10 kA in it. Model-ing is implemented using the Particle CST Studio package. The experiments were conducted on the U-3 accelerator of the ELMI installation. In calculations with three-dimensional geometry corresponding to the experiments, the distribu-tion of electron velocities over the pitch angle at the exit of the beams from the diode under the conditions of an inho-mogeneous magnetic field with an induction of about 1 T was obtained. These calculated data were confirmed in an experiment in which, using a sensor with seven recording channels, a distribution function of the velocity of electrons with a characteristic width at half maximum of 0.03 rad was obtained. Using the GEANT4 software package in processing measurement results with this sensor gives confidence in the correctness of the obtained distribution function.

Testo completoAbstract (sommario):
A computer model has been developed to investigate the processes of heat and mass transfer under the influence of concentrated energy sources on materials with specified thermophysical characteristics, including temperature-dependent ones. The model is based on the application of the volume of fluid (VOF) method and finite-difference approximation of the Navier–Stokes differential equations formulated for a viscous incompressible medium. The “predictor-corrector” method has been used for the coordinated determination of the pressure field which corresponds to the continuity condition and the velocity field. The modeling technique of the free liquid surface and boundary conditions has been described. The method of calculating surface tension forces and vapor recoil pressure has been presented. The algorithm structure is given, the individual modules of which are currently implemented in the Microsoft Visual Studio environment. The model can be applied for studying the metal transfer during the deposition processes, including the processes with electron beam spatial oscillation. The model was validated by comparing the results of computational experiments and images obtained by a high-speed camera.

Testo completoAbstract (sommario):
Lukulo upstream watershed is one of the watersheds in Central Java Province, which passes through 3 districts; Kebumen, Wonosobo, and Banjarnegara. Lukulo upstream watershed has eight sub-watersheds located in areas with diverse topography and lithology. The diversity of topography and lithology affects the characteristics of the area, as does the physical condition of the soil. The physical condition of this soil affects the runoff. Soil’s physical properties control rainwater to run off and have important effects on runoff behavior in watersheds. This study aims to determine the physical properties of the soil against runoff in each sub-watershed and each part of the watershed. The method used uses a laboratory, studio, and field approach. The results obtained show that the physical properties of the soil in the Lukulo upstream watershed affect the amount of runoff resistance in the upstream area; in the downstream area the runoff is relatively good. The study also shows two different results. In the Loning watershed, the velocity of downstream runoff is higher than the upstream, while in the Lokidang and Medana watershed, level of surface water flow is lower in the downstream area.

Testo completoAbstract (sommario):
The study purpose was to assess PSA velocity (PSAV) in healthy subjects in order to establish a reliable cutoff for the differential diagnosis of prostate cancer in a screening setting. We studied a series of 1666 healthy men aged 55 to 74 years undergoing two total PSA determinations at a four-year interval within a population-based randomized screening trial at the Centro per lo Studio e la Prevenzione Oncologica of Florence. First and second screening round PSA assays (PSA1 and PSA2) were carried out with the same method and by the same laboratory. PSAV (PSA1–PSA2/year) was determined in non-cancer subjects in the overall series or in specific age and PSA subgroups, and in subjects with cancer detected at the second screening round. Average PSAV in 1648 non-cancer subjects was 0.07 ng/mL/year (range −2.18+5.99, 95% CI 0.05–0.09); at least one third of subjects showed a decrease in PSA (negative PSAV), mostly of limited magnitude and in the low PSA range. Average PSAV in the 18 cancer patients was 1.16 ng/mL/year (range 0.10–5.6, 95% CI 0.56–1.77), which is significantly higher (p<0.01) than in non-cancer subjects. None of the cancer patients showed a PSA decrease over time. Whatever cutoff was taken for PSAV, its power to discriminate cancer was limited: in particular the previously used PSAV cutoff of 0.75 ng/mL/year would have included only 42 of the 1648 non-cancer subjects (specificity 97.5%) but excluded eight of the 18 cancer patients (sensitivity 55.5%). At best, with the adopted screening protocol PSAV (cutoff 0.10 ng/mL/year) could have spared 27.9% of non-cancer subjects with PSA ≥2.5 ng/mL further diagnostic assessment and 22.7% of non-cancer subjects with PSA ≥4 ng/mL random sextant biopsy, while missing no cancers. This study provides a reliable estimate of PSAV based on a large unbiased population sample. PSAV is widely variable over time, particularly at low PSA values. PSAV might be of value as an indicator for diagnostic assessment and random sextant biopsy in a screening setting.

The work of embankment in the main dam with an upright core consists of 5 pile zones: the core, filter, random, rock, and rip-rap. There was difference in planning and implementation of embankment filling. Random and rock used quarry Bondrang in planning but blasting upstream of the excavated material was used in implementation. This difference is because there are social problems with the community surrounding the Bondrang quarry. The purpose of this thesis is to repair the dam foundation, to find out the seepage discharge, to analyze the possibility of piping, to determine the safety factor of slope stability in the dam, and to determine RAB Maindam of Bendo Dam Project Ponorogo. The required data were of the geologic of the dam foundation, embankment materials, cross-sectional images of the dam body, and dam technical. Repairing the foundation using 3 methods : curtain grouting, consolidated grouting and blanket grouting; and for seepage calculations using the Cassagrande formula; to calculate safety figures using the Fellenius method and use the Geo-Studio 2012 application, the Seep / W program to find out the seepage discharge and the Geo-slope program to find out slope stability in maindam. The analysis resulted in 3 methods of repairing dam: curtain grouting with a depth of 39.83m, consolidated grouting with a depth of 5m, and blanket grouting with a depth of 15m; seepage discharge capacity <1% passing water average meaning safe; velocity seepage (7,3816 x 10-7m/sec) < velocity critical (0,004017m/sec) and 11,97 > 4 meaning safe for piping; >1.5 slope stability in various conditions without earthquake load meaning safe; 1.2 slope stability in various conditions with earthquake load meaning safe; the estimated cost IDR290,388,884,070.62 for main dam

Abstract Extreme conditions will cause the water level of high fill canal segment to change suddenly, which will affect the velocity and pore pressure of the slope. A 9 km irrigation earth canal in the city of Alsyahy, 15 km away from Al-Hilla city, and branching off from the left side of Shatt Al-Hilla at 57 km, was studied. The aim of this work is to study and analyze the effect of rationing system on the Birmana earthen canal during rapid drawdown case. Finite element modeling with Geo-Studio software was used in the present study to analyze the combined seepage and slope stability for three cycles. The resulting minimum safety factor obtained from the analysis using the saturated and unsaturated soil model was found to be 1.161, 1.142, 1.159, and 1.2 from the Janbu, Bishop, Morgenstern-Price, and Spencer methods, respectively. The factor of safety (FOS) values in three cycles are less than the required value. Finally, the FOC decreased by 66% from its value before the rationing system was applied, the area of canal and slip surface increased by 77 and 14%, respectively, due to the applied rationing system.

Big data is a large set of structured or unstructured data that can collect, store, manage, and analyze data with existing database management tools. And it means the technique of extracting value from these data and interpreting the results. Big data has three characteristics: The size of existing data and other data (volume), the speed of data generation (velocity), and the variety of information forms (variety). The time series data are obtained by collecting and recording the data generated in accordance with the flow of time. If the analysis of these time series data, found the characteristics of the data implies that feature helps to understand and analyze time series data. The concept of distance is the simplest and the most obvious in dealing with the similarities between objects. The commonly used and widely known method for measuring distance is the Euclidean distance. This study is the result of analyzing the similarity of stock price flow using 793,800 closing prices of 1,323 companies in Korea. Visual studio and Excel presented calculate the Euclidean distance using an analysis tool. We selected “000100” as a target domestic company and prepared for big data analysis. As a result of the analysis, the shortest Euclidean distance is the code “143860” company, and the calculated value is “11.147”. Therefore, based on the results of the analysis, the limitations of the study and theoretical implications are suggested.

Influenced by meteorological and environmental factors, ice flood is easy to occur in cold areas, causing the flood level to rise substantially and threatening the safety of embankments. Based on the analysis of the influencing factors of the seepage of the dike in the cold region, the seepage simulation model of the dike is constructed and solved by the SEEP/W module of Geo-studio software. The seepage of the Dike Section in the ice flood season and non-ice flood season under the scenario of 100-year flood level is compared and analyzed. The results show that, (1) The seepage path of non-ice flood dike mainly passes through the base layer of the dike, and the seepage path of the dike is affected by the frozen shell during the ice flood season, and the seepage path of the dike mainly passes through the frozen shell. (2) The maximum velocity of Dike Seepage in the season of ice flood is higher than that in non-ice flood season, which is easy to cause piping and collapse. (3) the maximum gradient of the embankment during the flood season has also increased, exceeding the allowable slope value of the project. During the season of ice flood, the embankment is unstable, and the embankment protection should be strengthened during the flood season.

Objective. The study aimed to assess the effects of high velocity low amplitude (HVLA) manipulations on force distribution, pressures, and balance in individuals with atlanto-occipital blockage, focusing on post-treatment improvements. Research methods. Diagnostic tests (cervical spine compression, Spurling, de Kleyn) and pedobarography (using an EPS/R2 mat and BIOMECH STUDIO software) assessed functionality and postural parameters pre and post HVLA therapy. Results. Initial diagnosis showed significant disturbances in force distribution, balance, and gait. Post-HVLA therapy improvements included: 1. Balanced forefoot load during standing, with a decrease in heel load percentage. 2. Improved global body pressure distribution, with a notable decrease in left-side body pressure. 3. Enhanced anteroposterior and lateral body oscillation ranges, with a reduced ratio of extreme deflection distances to deflection surface and a decreased average speed of displacements. 4. Normalization of the right foot abduction angle, with no significant change in the left foot's visitation angle. 5. Slight improvements in foot vault index (AI) and average foot pressure during gait, with minimal changes in maximum foot pressure during gait. Conclusions. HVLA manipulation significantly improves static balance parameters but shows minimal improvement in gait parameters. This indicates a complex relationship between atlanto-occipital blockage and postural disorders, suggesting the need for further research to explore the association between postural defects and atlanto-occipital transition blockage, as well as the impact of these blockages on postural changes.

The article is an independent work containing the author’s ingenious research methodology and the model of the control system of Unmanned Aerial Vehicles. Furthermore a unique and world first mathematical model of an Unmanned Aerial Vehicle was developed, as well as a simulation program which enabled to investigate the control system of any Unmanned Aerial Vehicles in the tilt duct pitch (altitude), bank (direction), deviation and velocity, depending upon the variable values of the steering coefficient, reinforcement coefficient and the derivative constant. The research program was written in the language of the C++ as the MFC class, on the MS Visual Studio 2010 platform. The main issue resolved in the article is the pioneering research of the process of control during manual and semi-automatic guidance of the Unmanned Aerial Vehicle, with a jet propulsion system to the coordinates of preset points of the flight route. Modelling of the flight control system takes into account: the logical network of operations of the simulation program, the pilot-operator model, the set motion and control deviations as well as the flight control laws. In addition, modeling of the control system takes into account the drive model, engine dynamics, engine thrust, the model of steering actuators and the model of external loads. In contrast, the external load model takes into account the external forces acting on the unmanned aircraft, including gravitational forces and moments, aerodynamic forces and moments, aerodynamic drag, aerodynamic lateral forces, aerodynamic lift forces, aerodynamic heeling moment, mechanism of local angle of attack from damping torque and forces and moments from the engine.

Indonesia is a tropical country that has two seasons, rainy and dry. Nowadays, the earth is experiencing the climate change phenomenon which causes erratic rainfall. The rainfall is influenced by several factors, one of which is the local scale factor. This research was aimed to build a rainfall model in Sulawesi to find out how the rainfall relationship with local scale factor in Sulawesi. In this research, the data used were secondary data which consisted of 15 samples with 6 variables from Badan Pusat Statistik (BPS). The limitation of the sample size in this study was due to the limited secondary data available in the field. The data was processed using Principal Component Regression Analysis. The first step was reducing local scale factor variables so that the principal component variable could be obtained that can explain variability from the original data which then that variable was analyzed using principal regression analysis. The data were analyzed by utilizing R Studio software. The results show that two principal component variables can explain 75.2% of the variability of original data and only one principal component variable that was significant to the rainfall variable. The regression model explained that the relationship between rainfall, humidity, air temperature, air pressure, and solar radiation was in the same direction while the relationship between rainfall and wind velocity was not in the same direction. Overall, the results of the study provided an overview of the application of the Principal Component Regression analysis to model the rainfall phenomenon in the Sulawesi region using the R program.

Aim. The article deals with developing software to simulate the motion of an object with the given parameters of initial and final phase status. Materials and methods. A motion error in sports exercise is the result of kinematic deviation from the parameters of a given motion program. The mathematical apparatus of adaptive control allows neutralizing motion mistakes between a program and a real trajectory. It is based on utilising the information about current parameters of a phase status of a moving object in a mathematical structure of the control function. The article proposes and experimentally proves the hypothesis about the computer synthesis of motions in biomechanical systems based on the mathematical apparatus of adaptive control. In the computational experiments, a mathematical description of an object is based on a well-established law of open-time approximation (A.P. Batenko, 1977), which requires that both velocity and coordinates simultaneously take the given values. Motion time in this law is an uncontrolled parameter. The mathematical model of a moving object is built as a system of a first-order differential equation. Results. A mathematical model describing the motion of a material point with given phase coordinates at the initial and final points in time is implemented in a computer program. The program works based on the integrated development environment Visual Studio Express 2013 and the Visual Basic 2010 language environment. Conclusion. The developed computer model of adaptive control achieves the aim of any motion, which implies transferring an object from a given initial state to the required final state.

The subject matter of this article is the process of subsonic air intake shaping for high-bypass ratio turbofan at the airplane preliminarily designing stage. The goal was to improve a mathematical model of V. I. Polikovskii method of subsonic air intake shaping for high-bypass ratio turbofan. The tasks are to consider the presence of cant of inlet cross-section, required to perform effective operation at airplane cruising angle-of-attacks; to increase the radius of curvature of the air intake lip to provide air flow near it without flow separation, which was definitely determined and could not be increased in the existing method; to improve constant length velocity gradient law (used in this method) so that too large duct expansion angles near the air intake outlet cross-section can be avoided; to consider the engine inlet spinner presence. The methods used are analytical and digital mathematical methods, implemented in MathCAD and Microsoft Visual Studio systems. The following results were obtained: based on the proposed method, new calculation module for the Power Unit software version 11.8 has been developed (С-language Win32 UNICODE application) with a friendly user interface. Conclusions. The scientific novelty of the results obtained is as follows: 1) mathematical model (algorithm and its program implementation) for circular turbofan air intake shaping has been improved considering cant of the inlet cross-section, air intake lip rounding with two radiuses, presence of engine inlet spinner, and zero expansion angles in the diffuser outlet cross-section; 2) adequacy of calculation results using the improved mathematical model is shown using comparison with shapes of circular turbofan air intakes, developed by the leading aviation companies.

The availability of fossil-based fuels will gradually decrease while the amount required increases. This has prompted research to find alternative energy sources, including bioethanol. Bioethanol, as an alternative energy source, can be used as a transportation fuel better than fossil-based fuels because ethanol has a high octane number, laminar velocity and heat of vaporisation. Meanwhile, the level of carbon and hydrocarbon emissions is low so it can increase combustion efficiency in vehicles. In addition, the use of bioethanol as fuel is environmentally friendly and renewable. Ethanol can be produced through a fermentation process using ethanol-producing yeast. Pineapple honey is known for its high sugar and other nutrient content, so it is supposed that many types of yeast can grow well in it. This study aims to isolation and screening of bioethanol-producing yeast from Pineapple Honey. This study was carried out by yeast isolation method, primary yeast screening, secondary yeast screening, and characterisation of selected yeast isolates. Data on ethanol production by yeast isolates were analysed by ANOVA with α=0.05 using the R studio program. This primary isolation and screening phase found eight yeast isolates capable of fermenting glucose and producing acid and gas in the test medium. Test ethanol production in DPE medium with 18% glucose content on all isolates showed that all isolates could produce ethanol with a range of 4.20-10.35%. Isolates of IK4 showed the highest ethanol production ability (10.35%) (p<0.5%) in significant contrast to the other seven isolates. Based on macroscopic and microscopic morphological characterisations, IKM 4 isolates show similarities to the genus Saccharomyces

Testo completoAbstract (sommario):
Oxidative stress has been recognized as the contributor to diabetic peripheral neuropathy (DPN). Antioxidant strategies have been most widely explored; nevertheless, whether antioxidants alone prevent DPN still remains inconclusive. In the present study, we established an in vitro DPN cell model for drug screening using Schwann RSC96 cells under high glucose (HG) stimulation, and we found that salvianolic acid A (SalA) mitigated HG-induced injury evidenced by cell viability and myelination. Mechanistically, SalA exhibited strong antioxidative effects by inhibiting 1,1-diphenyl-2-picrylhydrazyl (DPPH) and reducing reactive oxygen species (ROS), malondialdehyde (MDA), and oxidized glutathione (GSSG) content, as well as upregulating antioxidative enzyme mRNA expression. In addition, SalA significantly extenuated neuroinflammation with downregulated inflammatory factor mRNA expression. Furthermore, SalA improved the mitochondrial function of HG-injured Schwann cells by scavenging mitochondrial ROS, decreasing mitochondrial membrane potential (MMP), and enhancing ATP production, as well as upregulating oxidative phosphorylation gene expression. More importantly, we identified nuclear factor-E2-related factor 2 (Nrf2) as the upstream regulator which mediated protective effects of SalA on DPN. SalA directly bound to the Kelch domain of Kelch-like ECH-associated protein 1 (Keap1) and thus disrupted the interaction of Nrf2 and Keap1 predicted by LibDock of Discovery Studio. Additionally, SalA significantly inhibited Nrf2 promoter activity and downregulated Nrf2 mRNA expression but without affecting Nrf2 protein expression. Interestingly, SalA upregulated the nuclear Nrf2 expression and promoted Nrf2 nuclear translocation by high content screening assay, which was confirmed to be involved in its antiglucotoxicity effect by the knockdown of Nrf2 in RSC96 cells. In KK-Ay mice, we demonstrated that SalA could effectively improve the abnormal glucose and lipid metabolism and significantly protect against DPN by increasing the mechanical withdrawal threshold and sciatic nerve conduction velocity and restoring the ultrastructural impairment of the injured sciatic nerve induced by diabetes. Hence, SalA protected against DPN by antioxidative stress, attenuating neuroinflammation, and improving mitochondrial function via Nrf2. SalA may be prospective therapeutics for treating DPN.

carefully considered to ensure that the water demand of the students and staff can be met effectively and efficiently. Calculations show that a water demand of 0.35 m3/min is required, and various existing pipe diameters are used, ranging from 65mm for the main pipes, 60mm and 50mm for the header pipes, to 40mm, 32mm, 30mm, 25mm, 20mm, and 15mm for the shaft pipes. However, after controlling for velocity values using Epanet software, it was found that some pipes had values below 1.8m/s and above 2.4m/s, which could compromise system efficiency. Therefore, the effective pipe diameter for the header pipes was found to be 125mm and 90mm, and for the shaft pipes, it ranged from 90mm to 15mm. The results of this study highlight that the clean water piping system in the STIBA building must be carefully designed and evaluated to meet the clean water demands of the students and staff effectively and efficiently. This can be achieved by selecting effective pipe diameters based on the Epanet calculations and ensuring that the velocity values remain within the specified limits.

The primary air fan functions as a primary air producer which is used as air to transport coal powder from the pulverizer to the burner to be burned in the boiler furnace. This study aims to obtain the effect of the rotation variation of fan to fluid flow characteristics such as the distribution of total pressure, the dynamic pressure, the pressure static contours, velocity distribution, and the fan optimal efficiency. This study was numerical study with simulated a backward impeller type centrifugal fan in a two-dimension model using Fluid Computational software with the multiple reference frame method with the variation of fan rotation. Based on the visualization of the pressure contour and velocity distribution, it could be concluded that there was a volute phenomenon, this was indicated that the greater the volume area in the volute is the greater the total pressure value too. Based on the visualization of the outlet velocity distribution at the position of -0,8531m to -1,01301m, it was found that the velocity is close to the value of 0 m/s2. It showed that the minimum velocity in the area due to the volute tongue radius occurs a flow collision and it impacted the velocity in the area decreased up to V=0. From the simulation results, it was found that the greater the fan rotation value was the greater the efficiency value too. It would be verified by the actual operating data of the centrifugal fan with a minimum rotation range value of 1194 rpm to a maximum of 1468 rpm

Studi relokasi hiposenter aftershock gempa Yogyakarta 2006 telah diteliiti melalui pengolahan data waveform aftershock gempa Yogyakarta pada 16 Juni s.d 5 Juli 2006. Data model kecepatan gelombang 1D Jawa Tengah digunakan sebagai model kecepatan awal. Identifikasi distribusi hiposenter gempa bumi diperoleh menggunakan metode Joint Hypocenter Determination (JHD) dan program Velest. Lokasi hiposenter ini selanjutnya di plot pada peta menggunakan GMT (Generic Mapping Tools). Hasil penelitian memperlihatkan bahwa persebaran hiposenter gempabumi membentuk tiga buah cluster, berada dibagian timur kemudian membelok ke arah selatan Sesar Opak. Hiposenter memiliki pola persebaran membentuk suatu bidang sesar. Kemudian, hasil penelitian menemukan adanya rambatan energi di sepanjang zona lemah Sesar Opak dari sesar aktif di bagian timur. Nilai RMS residual relokasi hiposenter menunjukkan hasil yang cukup akurat yaitu sebesar 0,0596 detik dan menghasilkan model kecepatan yang tidak jauh berbeda dengan model kecepatan awal (Jawa Tengah). The relocation study of the 2006 Yogyakarta earthquake aftershock hypocenter has been investigated through the processing of the Yogyakarta earthquake aftershock waveform data from 16 June to 5 July 2006. Data from the 1D wave velocity model of Central Java is used as the initial velocity model. Identification of the earthquake hypocenter distribution was obtained using the Joint Hypocenter Determination (JHD) method and the Velest program. The hypocenter location is then plotted on the map using GMT (Generic Mapping Tools). The results showed that the hypocenter of the earthquake formed three clusters, located in the eastern part and then veered to the south of the Opak Fault. The hypocenter has a distribution pattern to form a fault plane. Then, the results of the study found energy propagation along the weak zone of the Opak Fault from an active fault in the eastern part. The RMS value of the residual hypocenter relocation shows a fairly accurate result of 0.0596 seconds and produces a velocity model that is not much different from the initial velocity model (Central Java).

The flow velocity and suspended sediment concentration are important parameters of sediment transport mechanisms, especially for agradation and degradation problems. The centrifugal force at the bend channels will increased flow velocity at the outer bank of the bend. It is of course also affects the distribution of flow velocity toward the outside and the inside of the bend channels. The change of the velocity distribution it is very possible also changes the distribution of suspended sediment concentration. In this paper will discuss the velocity distribution profile and distribution of sediment concentration in the bend flow. This research was conducted at Mataram Irrigation Channel Yogyakarta. The channel rectangular in shape and made of masonry with angle bend 580. Measuring the flow velocity used Propeller currentmeter and sediment concentration used Opcon Probe. Measuring flow velocity and sediment concentration conducted simultaneously for each measurement point.The results showed that due to the centrifugal force in bend flow, flow velocity distribution and sediment concentration distribution undergoing significant change the outside and the inside of the bend. In general, the distribution of flow velocity toward the outerbank of the bend has increased and the distribution suspended sediment concentration has decrease and the opposite occurs innerbank of the bend. A low velocity on the inner bank of the channel bend causes larger grains of sediment that settles and potentially silting.

Design and experiment of ocean current power generation system have been carried out using the Bach Savonius rotor. In this research, the influence of the velocity of ocean currents, the number of turbine blades, and the blade arc angle of the generator output power are studied. The results showed that the turbine output power is strongly influenced by the velocity of ocean currents where the velocity values of ocean currents varied in the range 0,63-1,98 m/sec. The maximum elctrical power of the turbine occurs at a current velocity of 1,98 m/sec of 26,88 Watts. The number of turbine blades has a significant effect on turbine output power. The turbine reaches maximum power is found in the rotor with a number of 3 blades with a power coefficient of 0,1176 on the tip speed ratio of 0,359. The blade arc angle is varied at angles of 90˚, 135˚ and 165˚. The blade arc angle 135˚ gives the best performance with a power coefficient of 0,102 on the tip speed ratio of 0,298.

Fresh fish is sensitive to storage temperature. Temperatures above 2 °C accelerate the growth of bacteria and cause spoilage. The optimal storage temperature for frozen fish is -20 °C. Reefer container with a closed cooling system serves to preserve by maintaining the temperature of frozen fish. The problem of this research is the uneven distribution of cold air in the reefer containers of the train, thereby reducing the quality of frozen fish. The purpose of this research is to increase the even distribution of air, velocity, and pressure in the reefer container of the train. The solution to the problem is simulation and analysis of the condition of the reefer container train using Computational Fluid Dynamics (CFD). Reefer containers without guide plates are simulated to find out the area of the train reefer containers that are not evenly distributed. The distribution of air in the reefer container of the train is improved even by the addition of guide plates with variations in angles of 40°, 50°, and 60°. This research produces qualitative data (velocity contour and pressure contour reefer container) and quantitative (average velocity and pressure). The results of this study are CFD simulation data of uniform distribution of air, speed, and pressure on the reefer container train with a 40⁰ guide plate.

ABSTRAK Relokasi hiposenter merupakan suatu metode yang digunakan untuk mendapatkan parameter-parameter gempa yang presisi. Parameter-parameter tersebut digunakan untuk studi tektonik lanjut seperti seismic hazard assessment pada suatu area. Penggunan model kecepatan 3-D secara teori akan memberikan hasil yang lebih baik dibandingkan dengan model 1-D karena model kecepatan di bawah permukaan bumi lebih mendekati model 3-D. Sebanyak 767 event gempa yang direkam oleh jaringan seismik DOMERAPI, MERAMEX, BMKG, dan BPPTKG digunakan pada penelitian ini. Gempa-gempa tersebut direlokasi dengan model kecepatan 3-D dan dianalisis untuk studi seismotektonik di wilayah Jawa Tengah dan sekitarnya. Hasil relokasi hiposenter menggunakan model kecepatan 3-D berhasil mendeteksi sejumlah fitur tektonik secara lebih jelas seperti struktur kolom yang berkaitan dengan Struktur backthrust di selatan Kebumen. Penampang vertikal arah barat-timur yang melewati Sesar Opak mengindikasikan arah dip bidang sesarnya ke arah timur. Zona seismik ganda yang terdeteksi pada studi sebelumnya tidak bisa teridentifikasi dengan baik pada studi ini. Sejumlah gempa volcano-tectonic (VT) berkaitan dengan aktivitas magma dangkal Gunung Merapi terdeteksi juga dengan jelas pada studi ini.ABSTRACT Hypocenter relocation is a method used to get precise earthquake parameters. They will be useful for an advanced tectonic study like seismic hazard assessment in an area. The hypocenter relocation using a 3-D velocity model will theoretically obtain better results than a 1-D velocity model because the earth subsurface model is closed with a 3-D model. Some 767 earthquakes recorded by DOMERAPI, MERAMEX, BMKG, and BPPTKG networks used in this research. They were relocated by using a 3-D velocity model and analyzed for seismotectonic study in Central Java area and its surroundings. The result of hypocenter relocation using a 3-D velocity model is successfully detecting some tectonic features more clearly like columnar structure related to the backthrust structure at the south of Kebumen. The west-east vertical cross-section crossing the Opak fault indicates the dip of the fault plane is directing to the east. This study could not identify the double seismic zone, which was detected by the previous research. Some volcano-tectonic (VT) earthquakes related to the shallow magma activity of Mount Merapi also are detected clearly in this study.
