The main concern of an olive grower is primarily to achieve more income and profits. A harvesting method having higher efficiency and better fruit and oil quality, but a higher operation cost leads to a lower benefit. A study was carried out to evaluate the techno-economic performances of Trunk Shaker (TS) and Mechanical Harvest Aid (MHA) shaker for harvesting the yellow and Manzanilla olive cu...
Humans have been harvesting wild populations for the entire extent of human history. In most early human societies, a successful hunt not only fed one’s family, but also brought respect from both family and community (Bolen and Robinson 2002). Although most North Americas and western Europeans today acquire their food that was planted, harvested, and processed by someone else, hunting and harve...
background and aims. during root canal preparation, debris extruded beyond the apical foramen may result in periapical inflammation and postoperative pain. to date no root canal preparation method has been developed that extrudes no periapical debris. the purpose of this study was to identify a system leading to minimal extrusion of debris from the apical foramen. the study was conducted to com...

The detailed reporting of any research intervention is crucial to evaluate its applicability into a routinely practice-based context. However, it has been estimated that, especially in non-pharmacological interventions, the published literature typically includes incomplete intervention details. In the field of manual medicine, where interventions are delivered with a high degree of individuali...
Wildflower harvesting is an economically important activity of which the ecological effects are poorly understood. We assessed how harvesting of flowers affects shrub persistence and abundance at multiple spatial extents. To this end, we built a process-based model to examine the mean persistence and abundance of wild shrubs whose flowers are subject to harvest (serotinous Proteaceae in the Sou...
Wild edible plants, ecological foodstuffs obtained from forest ecosystems, grow in natural fields, and their productivity depends on their response to harvesting by humans. Addressing exactly how wild edible plants respond to harvesting is critical because this knowledge will provide insights into how to obtain effective and sustainable ecosystem services from these plants. We focused on bamboo...
Models and experiments of the evolution of ageand/ or size-at-maturation in response to population harvesting have consistently shown that selective harvesting of older and larger individuals can cause earlier maturation. These predictions, however, are all based on single-species considerations and thus crucially neglect the selective forces caused or mediated by species interactions. Here we ...
OBJECTIVE Preparation of the great saphenous vein for coronary artery bypass grafts is usually performed through one or many cutaneous incisions. A technique of endoscopic harvesting is now available. An aim of the study was to compare both methods, prospectively. METHODS Sixty coronary artery bypass grafting patients were randomly assigned to two groups according to saphenous vein harvesting...
Hematopoietic stem and progenitor cell (HSPC) transplantations require prior harvesting of allogeneic or autologous HSPCs. HSPCs are usually present in bone marrow (BM) during the entire life, in cord blood (CB) at birth, or in peripheral blood (PB) under particular circumstances. HSPCs were first harvested in BM and later in CB and PB, as studies showed interesting features of such grafts. All...
