Different extractives of Syzygium cumini seeds were evaluated by free radical (DPPH) scavenging assay, phosphomolybdenum total antioxidant assay and reducing power determination in order to identify promising sources of ...

Abstract With the increasing performance requirements for data acquisition in applications such as the Internet of things and artificial intelligence, analog-to-digital converters (ADCs) face stringent trade-offs among s...

Power plant projects are crucial to providing andining a reliable power system. Power plant projects, like other construction projects, often experience a problem of delayed completion of work known as time overrun, whic...

Nowadays, offshore renewable energy is seen more and more as an attractive alternative to onshore energy thanks to less space limitations and usually better weather conditions. However, the higher costs in installation a...

The incorporation of wind generation in microgrids is growing progressively. This integration can introduce problems in the dynamics and power quality of the electrical system due to the wind fluctuations. This work prop...

Listeria monocytogenes is a foodborne pathogen. The recent alert for L. monocytogenes in vegetables from Argentina warns about the importance of reinforcing its isolation, characterization and subtyping in food, clinical...

Considering the diffuse character Foucault attributes to power relations, it is possible to assert that the subjection of bodies is never absolute, so they are not inexorably determined by the exercise of power. This art...

A energia eólica tem experimentado um exponencial e virtuoso crescimento no Brasil. De 2009 a 2012, nos seis leilões em que a fonte eólica participou, foram contratados 7 GW em novos projetos representando mais de 25 ...

Animals respond to environmental variation by exhibiting a number of different behaviours and/or rates of activity, which result in corresponding variation in energy expenditure. Successful animals generally maximize eff...

Por motivos não abordados neste artigo, projetos importantes sofreram atrasos em seus cronogramas, aumentando o risco de que, em futuro próximo, o Brasil venha a enfrentar uma crise de abastecimento de energia elétric...

Solar panels consist of photovoltaic cells which are identical to diode semiconductor devices. Photovoltaics have a special point which is usually called MPP (Maximum Power Point). At that point, the photovoltaic is in a...

O presente artigo analisa outra vertente (por vezes ignorada ou subestimada) do conceito de poder, o soft power, relacionando-o com o caso concreto de uma potência em ascensão: a China. Inicia-se por definir a noção ...

Abstract With the increasing penetration of power electronic devices in power systems, virtual synchronous generator (VSG) technology has garnered widespread attention for its ability to provide inertia and damping suppo...

Renewable energy is energy that comes from natural resources that are continuously available. Renewable energy will replace fossil fuels that will slowly run out, fossil fuels such as oil, gas and coal. Dependence on fos...

Background and Study Aim. Youth tennis performance depends on the development of multiple physical domains, including speed, agility, power, accuracy, and endurance. Although numerous training interventions have been pro...

The role of Ukraine on the global geopolitical stage from 1991 to 2025 is analyzed. Based on geopolitical conclusions drawn from the works of scholars such as H. Mackinder and Zb. Brzezinski, the geostrategic importance ...

Recent historical works dealing with the changing role of emotions in social and private life over centuries present a challenge to any philosophical or scientific theory aiming to grasp the essence of emotions. The pape...

This study compares seven quantum algorithms—Variational Quantum Eigensolver (VQE), Variational Quantum Deflation (VQD), Quantum Approximate Optimization Algorithm (QAOA), Quantum Amplitude Estimation (QAE), Quant...

With the rapid evolution of virtual reality technologies such as digital twins, industrial Internet of Things, edge intelligence, and metaverse, virtual‒reality integration has become a core driving force for the const...

A temperature-doubler circuit is the functional equivalent of a voltage-doubler in the thermal domain. Effective temperature-doubler circuits could benefit energy scavenging from fluctuating thermal resources, e.g. the d...

The use of neutral point clamped (NPC) multilevel inverters has significantly increased in recent decades, due to their appealing features compared to two-level voltage source inverters. In many industry-level applicatio...

There is something essential we need to know of power that is visible only when power makes certain exceptions. Power, we are arguing, is fundamentally without content. This occluded piece of information about power is p...

Gravity Water Vortex Turbines (GWVTs) are a new category of turbines used in micro-hydro power plants (MHPs). GWVTs can be used to optimize existing water flow potential, aerate water bodies, and maintain ecosystem integ...

Ecological cities seek to create a sustainable balance between human activities and the environment. Based on the objective, this is applied-developmental research. In the qualitative section, grounded theory and MAXQDA ...
