BACKGROUND The time required to harvest plant crops is important to the plant properties. It is affected by design of the harvest equipment and the desire for high-quality products with low energy usage. MATERIALS AND METHODS Strength characteristics of Origanum onites L., an important medicinal aromatic plant, harvested on 2, 9, 16 and 23 July, 2012-2014 (H1, H2, H3 and H4, respectively) wer...

Introduction: Although, the effect of direct intra-articular injection of bone marrow stem cells (BMSCs) on the repair of articular cartilage and the effect of Elaeagnus angustifolia extract on pain relief in patients with osteoarthritis have been investigated, no studies has been conducted to compare the effects of these two therapeutic methods on the mechanical properties of articular cartila...

During the ageing period, meat organoleptic properties change, in particular tenderness due to proteolytic and derivative processes. The aim of this study was to evaluate the development of this qualitative parameter in beef during the first 10 days post-mortem in two different muscles (longissimus thoracis -LT and semitendinosusST) of 8 young bulls. Shear force in cooked meat was higher in ST ...

the shear strength and shear energy per unit area, as well as the force and energy required for picking flowers, are important parameters in the design and development of harvesting mechanisms. in this study, shear strength and shear energy per unit area of saffron (crocus sativus l.) stems were determined at different bevel angles and shear velocities. the force and energy required for picking...

Press-fit acetabular shells used for hip replacement rely upon an interference fit with the bone to provide initial stability. This process may result in deformation of the shell. This study aimed to model shell deformation as a process of shell stiffness and bone strength. A cohort of 32 shells with two different wall thicknesses (3 and 4 mm) and 10 different shell sizes (44- to 62-mm outer di...

Elastic deformation on the surfaces of molecular crystals can be imaged using a variant of lateral force microscopy in which the tip is scanned parallel to the cantilever axis. The shear force transverse to this direction has a distinctly different origin than the friction force as determined by the tip velocity and temperature dependence of the cantilever torque. An elastic deformation model f...

Based on the application of a beam-column joint with replaceable energy-dissipating elements and hinged proposed by author, seismic performance fully assembled steel frame this was investigated in paper. Through two projects traditional (TSF) an applying joints (ASFWREE) their numerical simulation calculation SAP2000, main structural design indicators such as natural vibration period, period ra...

INTRODUCTION Landing mats that undergo large area deformation are now essential for the safe completion of landings in gymnastics. The aim of this study was to determine the effective mass, shock transmission time, and deformation characteristics of a mat during impacts using high-speed video and to improve the accuracy of measuring foot-mat contact forces during landing. For validation, the sa...

A sheet-type shear force sensor and a measurement system for the sensor were developed. The sensor has an original structure where a liquid electrolyte is filled in a space composed of two electrode-patterned polymer films and an elastic rubber ring. When a shear force is applied on the surface of the sensor, the two electrode-patterned films mutually move so that the distance between the inter...
