The potential of natural resources in the form water energy is a renewable resource that often used because it does not damage environment and can be continuously. This flow has two types, namely laminar turbulent flow, forces generated from these flows are also different. Turbulent tends to produce greater force lift object masses better than flow. Therefore, vortex turbine emerged which utili...

Abstract Agricultural practices in northern Sudan have been changing rapidly but remain little documented. In this paper we aim to investigate changes crops grown living memory and their uses through interviews with Nubian farmers on the island of Ernetta. By exploring cultivation crop processing practices, together associated material culture foodstuffs, also seek explore how agricultural food...

Desorption electrospray ionization mass spectrometry (DESI-MS) previously has been used to capture and identify transient intermediates in electrochemical redox reactions on a platinum-covered rotating waterwheel. We present here two different setups that use a flat surface with porous carbon tape as the working electrode, where analyte-containing microdroplets from the DESI probe contacted wit...

This paper aims to present a novel approach to conceptualize basic mechanics for exterior façade shading systems by investigating kinematics of complex plant movements that are based on reversible elastic deformations. In an interdisciplinary collaboration between architects, engineers, and biologists; autonomous and non-autonomous flower opening and leaf folding processes were tested for their...

Nowadays, the energy transition from fossil fuels to renewable energies is taking place worldwide. Every year, amount of installed increases dramatically. Many small-scale technologies have been developed, for example at household level, or environmental level as community-owned energy. This research focuses on development technology using resource potential and local community wisdom Glintung ...

Malaria remains one of the major vector-borne diseases in the world. It is responsible for approximately one million deaths per year, mainly of children below the age of five, particularly in Sub-Saharan Africa [1]. Mosquitoes of the genus Anopheles are the sole vectors of malaria in subSaharan Africa [2]. Current vector control methods are based on larvicide application in breeding sites, indo...

This article deals with the development of sawmilling over the area of the Czech Republic from the invention of the waterwheel drive until the present day. This survey is based on the writings of various Czech authors who were engaged, or still are, in this subject. The two most common types of machines in water-driven sawmills were both used at that time: the single-blade vertical frame saw an...
