Nanosized CuFe2O4 ferrite was synthesized through the sol-gel self-combustion technique, using iron and copper nitrates with citric acid as fuel. The synthesized ferrite was subsequently analyzed using X-ray diffraction ...

Porous carbon materials (PСM) with different pore distributions in size and size of the specific surface area up to 250 m2/g were obtained by changing the carbonization temperature of plant biomass, namely walnut shells...

Abstract In the process of grinding carbon fiber reinforced polymer (CFRP), the changing state of acceleration vibration signal is closely related to the grinding surface quality. Therefore, the time domain and frequency...

Global warming which results in climate change resulting in an increase in air temperature and rainfall is a major problem in the world, especially Pekanbaru City. The significant increase in air temperature and rainfall...

Abstract Fuel consumption is one of the main concerns for heavy-duty trucks. Predictive cruise control (PCC) provides an intriguing opportunity to reduce fuel consumption by using the upcoming road information. In this s...

Despite the pressing demand for integrated spectrometers, a solution that deliver high-performance while being practically operated is still missing. Furthermore, current integrated spectrometers lack reconfigurability i...

ABSTRACT The aim was to report two cases of accidental Brodifacum poisoning in calves on a dairy farm. The animals presented a variable clinical picture of bleeding disorders with melena, epistaxis, orthopneic position, ...

The problem of stochastic averaging of the decayed dynamics of the output state population of a one-step transformation process with constant deterministic forward transition rate and randomly varying return transition r...

The article substantiates the fact that several approaches should be considered when building an organizational and economic mechanism for the development of woodworking enterprises, in particular: process-based, innovat...

Background Understanding the evolution of circadian rhythm dysfunction and psychopathology in the high-risk population has important implications for the prevention of bipolar disorder. Nevertheless, some of the previous...

The performance of all active photonic devices today is greatly limited by loss. Here, we show that one can engineer a low loss path in a metal-clad lossy multi-mode waveguide while simultaneously achieving high-performa...

In the equiatomic approximation, the dependence of the lattice FCC parameter and the Debye temperature from the atomic fate x of the doping element, which is alternately represented by all elements of a multicomponent so...

Creative use of media will increase the possibility for students to learn more, embed what they learn better, and improve performance in carrying out skills according to learning objectives. Podcast media has recently be...

Este trabajo reflexiona sobre las formas de producción de conocimiento situado y dialó-gico, desde la integralidad de funciones universitarias, en procesos colaborativos que en-traman relaciones ...

Abstract It is difficult to effectively improve the low bonding strength of TA1/304 clad plates. This study proposes a new process for applying pulse current (1500 A, 500 Hz, 50% duty cycle) to TA1/304 clad plates duri...

Background/Aim: The present study investigates the effectiveness of Invisalign (Align Technology, San Jose, Calif) in rotational tooth movement. The aim of this research is to assess the accuracy of the predicted rotatio...

Abstract Endometriosis is a complex disease that affects 10-15% of women of reproductive age. Familial studies show that relatives of affected patients have a higher risk of developing the disease, implicating a genetic ...

ABSTRACT Sarcophagidae flies have great forensic importance, since different instars of their larval development are used in the determination of the postmortem interval (PMI) of corpses. However, for many species, intra...

This article synthetically discusses the judgment of the Court of Justice of the European Union of 2 March 2023 in case C-432/21. It aims to familiarise international readers with this issue, which might be a contributio...

Chiral optical forces exhibit opposite signs for the two enantiomeric versions of a chiral molecule or particle. If large enough, these forces might be able to separate enantiomers all optically, which would find numerou...

Celem artykułu jest przedstawienie metod wartościowania projektów nowego produktu w procesie rozwoju nowego produktu, a także zaproponowanie nowej metody optymalizacji wartości portfela projektów nowych produktów ...

Due to signal shielding caused by building structures, conventional mature positioning technologies such as the Global Positioning System (GPS) are only suitable for outdoor navigation and detection. However, there are m...

Abstract Global health reciprocal innovation emphasizes the movement of technologies or interventions between high- and low-income countries to address a shared public health problem, in contrast to unidirectional models...
