Objective: In recent years, farmers have shown great interest to using native drill planter rather than complex planters to grow vegetables. Methods: In this study, we tested a native planter Independent variables were the two types of substrate surface (asphalt and plowed field), three ground speed (3, 5 and 7 kph) and four types of seeds (tomatoes, onions, radishes and lettuce). Dependent var...

Two-dimensional (2D) ferrovalley materials that exhibit spontaneous valley polarization are both fundamentally intriguing and practically appealing to be used in valleytronic devices. Usually, the research on 2D is mainly focused inorganic systems, severely suffering from in-plane magnetization. Here, we alternatively show by k\ifmmode\cdot\else\textperiodcentered\fi{}p model analysis high-thro...

This paper presents a three-dimensional heat transfer analysis of flat-plate oscillating pipe (OHP). To enhance implementation OHPs in various applications, it is important to understand the comprehensive phenomena that include thermal diffusion whole structure and hydraulics channel. We developed an OHP model includes effect thermo-fluid behavior. The was validated with experimental results al...

The main goal of this study was to verify the best combination density, moisture content, and feed speed on surface quality Pinus elliottii boards aimed at deck manufacturing. secondary compare three methods assessment. Tangential were sampled sorted by density (level 1: 414 kg·m–³ 525 kg·m–³; level 2: 526 668 kg·m–³) content 13.5% 17.5%; 17.6% 20.0%). A four-side planer molder used, levels (15...

Wearable electronics offer incredible benefits in mobile healthcare monitoring, sensing, portable energy harvesting and storage, human-machine interactions, etc., due to the evolution of rigid structure flexible stretchable devices. Lately, transition metal carbides nitrides (MXenes) are highly regarded as a group thriving two-dimensional nanomaterials extraordinary building blocks for emerging...

As “Industry 4.0” progresses, construction machinery is evolving toward large-scale, automation, and integration, resulting in the equipment becoming increasingly sophisticated, designs more difficult. Labor costs, transportation, time will be huge challenges for machinery, mixed reality technology one of several possible ways to solve this challenge. The research presented paper develops a hol...

Denna bok lyfter frågan om hur vilka planer som finns i Ryssland för tiden efter Putin president. Huvudargumentet är att de strategier bygga politisk legitimitet nästan helt har fokuserats på Rysslands räddare och beskyddare. Därmed också möjliga efterträdare svårt upp en egen plattform. Den nya konstitutionen möjliggör sitta kvar fram till 2036 visar man inte någon lösning detta dilemma. Kvar ...
