In today's world, there is a huge demand for portable electronic systems such as RFID cards, PDA, watches, calculators, cell phones, flash memories, MEMS, LCD drivers etc. The limited battery lifetime is the main concern of many portable systems. Energy harvesting system overcomes these problems by converting non-conventional energy into useful energy. The power converter plays an importan...
Rainwater harvesting (RWH) is a method of inducing, collecting, storing and conserving local surface runoff for agricultural production. This paper presents a brief treatise, of rainwater harvesting, and its historical perspectives. The paper reviews major techniques of RWH for crop production being practised. These fall into three broad categories namely: In-situ, Internal (Micro) and External...
Yong-Woong Jang 33 A numerical simulation and an experimental implementation of T-shaped microstrip-fed printed slot array antenna are presented in this paper. The proposed antenna with relative permittivity 4.3 and thickness 1.0mm is analyzed by the finite-difference time-domain (FDTD) method. The dependence of design parameters on the bandwidth characteristics is investigated. The measured ba...
Bone grafting is a commonly performed surgical procedure to augment bone regeneration in a variety of cases in orthopaedic and maxillofacial surgery. Autologous bone graft remains to be the 'gold standard' and the iliac crest to be the most common harvesting site. The intramedullary canal of long bones represents another potential site for large volume of autologous bone graft harvesting and is...
The main purpose of this study is measuring and comparing of peanut harvesting loss in manual and mechanical methods in addition to economic analysis of them. Hence, a field was selected in Astaneh-Ashrafiyeh and divided to three different plots. Two plots were applied to measure mechanical harvesting loss and third one was applied for manual harvesting loss. According to test results, the lowe...
The growth of the blueberry industry in the past three decades has been remarkably robust. However, a labor shortage for hand harvesting, increasingly higher labor costs, and low harvest efficiencies are becoming bottlenecks for sustainable development of the fresh market blueberry production. In this study, we evaluated semi-mechanical harvesting systems consisting of a harvest-aid platform wi...
The anterior iliac crest is the harvest site preferred by many surgeons because of the quantity and quality of bone obtainable and the simplicity of harvesting techniques. Avulsion fracture of the iliac crest following bone grafting is an extremely rare occurrence. We present a case report of avulsion fracture of the anterior iliac crest following bone graft harvesting for anterior cervical fus...
Ecosystem services are fundamental for human well-being and are the basis of rural livelihoods, particularly for poor people. Rainwater harvesting can serve as an opportunity to enhance ecosystem productivity, thereby improving livelihoods, human well-being, and economies. Rainwater harvesting has been shown to create synergies between landscape management and human well-being. These synergi...
An important route to understanding how proteins function at a mechanistic level is to have the structure of the target protein available, ideally at atomic resolution. Presently, there is only one way to capture such information as applied to integral membrane proteins (Figure 1), and the complexes they form, and that method is macromolecular X-ray crystallography (MX). To do MX diffraction qu...
