Calcium pyrophosphate deposition disease: points to be considered for quality assurance in clinical practice
Authors: Schirmer Michael , Pallua Johannes Dominikus
Published: July 2024

Calcium pyrophosphate deposition disease is known as crowned dens syndrome or peripheral arthritis, especially of knees, hips and shoulders. The disease course is asymptomatic, with acute or chronic disease activity related to osteoarthritis, especially in the elderly. Other risk factors are joint injury, osteoarthritis and metabolic conditions such as primary hyperparathyroidism, hemochromatosis, hypophosphatasia and hypomagnesemia. Genetic background should be considered before the age of 55 years. Only recently was the value of signs and symptoms weighted, allowing the introduction of classification criteria. Biomarkers include compensated polarized light microscopy findings, laboratory values and imaging. Imaging evidence refers to calcification of the fibrocartilage or hyaline cartilage. Chondrocalcinosis defined as such cartilage calcification is most commonly due to calcium pyrophosphate deposition disease. Calcification of the synovial membrane, joint capsule, or tendon should not be scored. Ultrasonography detects calcium pyrophosphate deposits with more than 80% sensitivity rates, which is superior to conventional radiography. In the future, dual-energy computerized tomography and Raman spectroscopy are promising new techniques to assess disease activity. Currently, the primary therapeutic goal is controlling inflammatory reactions and preventing further episodes. However, only hydroxychloroquine and magnesium carbonate have shown some efficacy and reduction of pain intensity so far. As patients report more significant unmet treatment needs than patients with gout, education is an essential issue of care. The new classification criteria will allow the validation of standardized outcome parameters with the definition of remission and low disease activity for developing treat-to-target strategies to perform well-designed interventional trials evaluating new treatment options and strategies.

The role of native language and beat perception ability in the perception of speech rhythm
Authors: Smit Eline A. , Rathcke Tamara V.
Published: July 2024

The perception of rhythm has been studied across a range of auditory signals, with speech presenting one of the particularly challenging cases to capture and explain. Here, we asked if rhythm perception in speech is guided by perceptual biases arising from native language structures, if it is shaped by the cognitive ability to perceive a regular beat, or a combination of both. Listeners of two prosodically distinct languages - English and French - heard sentences (spoken in their native and the foreign language, respectively) and compared the rhythm of each sentence to its drummed version (presented at inter-syllabic, inter-vocalic, or isochronous intervals). While English listeners tended to map sentence rhythm onto inter-vocalic and inter-syllabic intervals in this task, French listeners showed a perceptual preference for inter-vocalic intervals only. The native language tendency was equally apparent in the listeners’ foreign language and was enhanced by individual beat perception ability. These findings suggest that rhythm perception in speech is shaped primarily by listeners’ native language experience with a lesser influence of innate cognitive traits.

Authors: Memic Faris , Catovic Alan
Published: July 2024

The study examines the results of numerical simulations of the penetration of a 7,62mm x 63, AP, M2 projectile through a target. Model validation involved a numerical simulation of 7,62mm x 63, AP, M2 projectile penetration through an AA5083H116 target, for which experimental results were available in the literature. The results of the numerical simulation were used for regression analysis - to calibrate the Recht-Ipson model for the given projectile. Furthermore, penetration analyses of 7,62mm x 63, AP, M2 projectiles through various target materials were performed at consistent projectile velocities and mesh sizes. As expected, bainitic steels exhibited the highest resilience, demonstrating that increased material hardness and tensile strength correlate with enhanced projectile penetration resistance.

In recent years, 3D printing technology has received a lot of attention. The use of 3D printing technology in many industries is widely accepted due to its low cost of production and capacity to manufacture complex and geometrical shapes. This paper presents the fabrication of probe holder by using 3D printing technology for ultrasonic scanner application. The fabrication of 3D printed probe holder began with the Taguchi technique design of experiment (DOE). Three major effects were identified: printing temperature, layer thickness and infill density. Solidworks software was employed to build the computer-aided design (CAD) model of the probe holder. Subsequently, the CAD model file is converted to Standard Tessellation Language (STL) file for 3D printing process. The probe holder was successfully fabricated using 3D printer without any defects visible on the outside surface of the 3D printed products. Based on bending test results, it can be concluded that the strength of probe holder was attributed by the layer thickness.

Redline Stealer is a malware variant discovered in early March 2020 by proof point analyst. Redline is famous for its ability to bypass the antivirus scan. Redline Stealer was created by hacker with the purpose to steal victim’s information such as login data, password and credit card information from the browser application that used in infected computer. This research uses static and dynamic method to analyze redline stealer. The process of static analysis is carried out by observing the malware’s sample file, while dynamic analysis is carried out by monitoring malware’s activity when the malware is running on the system. In this research show that Redline Stealer is uses the obfuscation feature, based on .net, can run only when there is internet connection, stealing sensitive information especially in browser application. The conclusion of this research is Redline Stealer can be classified as a stealer malware that can steal important data on the infected system. The result of the analysis using the strings extract and decompile did not find any information because this malware uses the obfuscation feature, so the static analysis did find fewer information than the dynamic method.
Energy and Exergy Analysis of R600a as a Substitute for R134a in Automotive Air Conditioning System
Authors: Muhammad Arman  , Kasni Sumeru  , Andriyanto Setyawan  , Luga Martin Simbolon  , Mohamad Firdaus Sukri
Published: July 2024

Until now, R134a is still used as a working fluid in automotive air conditioning (A/C) even though it has a very high global warming potential (GWP), which is 1430. Refrigerant R600a is an alternative working fluid as a substitute for R134a in automotive (A/C). This environmentally friendly substitute refrigerant is also expected to produce a better system performance, for which it is necessary to analyse energy and exergy. During work, each AC component generates friction, heat loss, and pressure drop which causes irreversibility in each component. The irreversible quantity of each component is calculated by exergy analysis. Because automotive A/C is driven by engine rotation, its performance is also affected by engine rotation. In this study, the engine rotation to be evaluated is 1000, 1500, 2000, 2500, and 3000 rpm. The evaporating and condensing temperatures of automotive A/C in this study were 5oC and 45oC, respectively. Based on the energy analysis it was found that replacing R134a with R600 enhanced COP, for example at 2000 rpm for R134a and R600a respectively were 3.59 and 3.69, or an increase in COP of about 3%. Based on the exergy analysis, the greatest irreversibility occurred in the compressor, namely 72.1% and 78.6% for R134a and R600a, respectively, for 2000 rpm. This means that there is a potential to enhance the COP improvement using R600a by reducing the irreversibility on the compressor.

Published: July 2024

This paper deliberates experimentally the inspiration of capacity flow rate of air bubbles inserted on the time period of a water cooler container with 30 liters of regular water initially at 37 °C. Four various volume flow rates of the injected air were used in the experiments (Qa=0.5; 1.0; 1.5 and 2.0 LPM). The air was injected into the water basin from the bottom as small air bubbles with an average diameter of (0.1 mm) via a spiral sparger made of silicon tube with (1400) holes and 0.1 mm hole diameter. In addition, four air pressures (P=2, 3, 4, and 5 bar) were used in the experiments. Consequences exhibited that the time required to cool down the water temperature (about 5 °C) was much smaller with injecting air bubbles than that of without injecting air bubbles (using the traditional cooling method). This consequence was more pronounced with amassed the volume airstream of the inserted air bubbles. The escalation the air volume flow rate, the quicker reduction the water cooling. Also, it was found that the pressure of the injected air bubbles had only a minor impact on the cooling process. Furthermore, the heat transfer and the cost of the cooling process with and without injecting air bubbles were studied. The heat transfer convection coefficient correlated of Nu was investigated to be increased with rising the volume flow rate of the injected air bubbles. Similarly, the cost of cooling down a specific amount of water was noticed to be decreased with increasing the injected air bubbles., The calculations illustrated that small air bubbles motility amount have a very significant guidance on time. The possibility of reaching the end of the cooling process can be achieved quicker as air flow rate amount is increased. It was clear how much electricity is saved using air bubble inoculation technique.

Climate change is still an important issue that needs concrete support and action. Refrigerant is also one material that affects global warming and international have plans to reduce the use of HFC refrigerants. Thailand also uses R404A refrigerant, which is an HFC refrigerant with a GWP of up to 3,129 and Thailand plans to reduce its use by 15% in 2030. R404A is the most widely used HFC refrigerant today because it can be used in both refrigeration and air conditioning systems. In the refrigeration system, which uses about 1 ton of refrigerant, when a leak occurs, in addition to affecting global warming and maintenance costs, it also affects the energy consumption of the refrigeration system. From data on the amount of refrigerant used in 2022, it was found that the use of refrigerant for maintenance is 25 tons, averaging 2 tons per month. This research will present the optimization of the maintenance refrigeration system by decreasing carbon emissions using ultrasonic sensors to keep the refrigerant level. The ultrasonic detects flat gas in refrigeration systems, which can detect fluid leaks rather than leaks. detector or using a sight glass. The results of the research found that when the refrigerant leak can be fixed quickly, it will save the use of refrigerant and help reduce energy. When fixing a leaking refrigerant system, 1) 10% will reduce energy by 7%. 2) 20% will reduce energy by 17% 3) 30% will reduce energy by 59%.

This study investigates the role of leadership in shaping the strategic management decisions of Micro, Small, and Medium Enterprises (MSMEs) owners in Indonesia. Utilizing a mixed-methods approach, we surveyed 250 MSME owners and managers across various sectors and conducted in-depth interviews to gain qualitative insights. Our findings reveal that entrepreneurial and transformational leadership styles are the most prevalent and influential, significantly driving strategic planning, innovation management, and competitive positioning. Transactional leadership, while important, plays a comparatively lesser role. Qualitative insights highlight the impact of personal networks, cultural values, and adaptive leadership in navigating regulatory challenges and leveraging government support. Additionally, digital transformation emerges as a critical factor for operational efficiency and market reach. These results suggest that leadership development programs should focus on enhancing entrepreneurial and transformational skills, and government policies should be tailored to the specific needs of MSMEs, with an emphasis on reducing bureaucratic barriers and improving digital literacy. This study provides valuable implications for policymakers and practitioners aiming to strengthen the strategic management capabilities of MSMEs in Indonesia.

Lost and Found: The Architectural Spice Box and the Context of Late Medieval Domestic Material Culture
Authors: Manor Hila
Published: July 2024

The architectural Jewish spice box is one of the famous material manifestations of the ritual of
havdalah
. Originating in the regions of medieval Europe, only a few examples have survived from that time, including the well-known spice box preserved in the Jewish Museum, New York, which had a “twin” that displayed an almost identical design. The twin, however, did not act as a spice box; instead, it was used as a centerpiece in courtly contexts. This article analyzes the relationship between the two objects and examines the emergence of the spice box in light of wider processes in late medieval Europe, where precious metal objects were commissioned by larger strata of society, including Jews. Following the context of courtly-domestic material culture, a possible account of the creation, acquisition, and significance of the New York spice box is presented.

We report observations of a powerful ionized gas outflow in the z = 4.1 luminous radio galaxy TNJ1338-1942 hosting an obscured quasar using the Near Infrared Spectrograph (NIRSpec) on board JWST. We spatially resolve a large-scale (∼15 kpc) outflow and measure outflow rates. The outflowing gas shows velocities exceeding 900 km s−1 and broad line profiles with widths exceeding 1200 km s−1 located at an ∼10 kpc projected distance from the central nucleus. The outflowing nebula spatially overlaps with the brightest radio lobe, indicating that the powerful radio jets are responsible for the outflow kinematics. The gas is possibly ionized by the obscured quasar with a contribution from shocks induced by the jets. The mass outflow rate map shows that the region with the broadest line profiles exhibits the strongest outflow rates. The total mass outflow rate is ∼500 M
⊙ yr−1, and the mass loading factor is ∼1, indicating that a significant part of the gas is displaced outwards by the outflow. Our hypothesis is that the overpressured shocked jet fluid expands laterally to create an expanding ellipsoidal “cocoon” that causes the surrounding gas to accelerate outwards. The total kinetic energy injected by the radio jet is about 3 orders of magnitude larger than the energy in the outflowing ionized gas. This implies that kinetic energy must be transferred inefficiently from the jets to the gas. The bulk of the deposited energy possibly lies in the form of hot X-ray-emitting gas.
