The use of biostimulants in high-density olive growing: Quality and production

[EN] Due to the increase of high-density holdings, especially of olive trees, the nutritional requirements of the plants are higher per unit area, which implies that a greater contribution of fertilizers to the soil is needed. Opting for fertilizers of inorganic origin will produce an increase in the pollution of the soil. In the face of this possible soil contamination, our aim is to analyze the effect of biostimulants as an alternative to chemical fertilizers, to steadily produce and maintain high quality standards during the life of the crop. Our objective is using more environmentally friendly products in order to satisfy one of the most important demands from both consumers and the authorities. In this study, we carried out five different treatments in addition to a control treatment with a supply of NPK, from inorganic products, which are used to control fertilization with a solution obtained from seaweed extracts. These treatments were applied in two crop cycles for two of the most important varieties in the current olive tree growing scenario: Arbequina and Koroneiki. This study was developed in the farm Pozohondo, which is located in a crop zone by the Palancia river (Castellón, Valencia, Spain), in the southeast of the Iberian Peninsula, where the olive trees were established in a high-density system with a planting framework of 4 x 1.5 m. We ensured an exhaustive control of the nutritional needs of the holding by using a fertigation system. We could notice differences in the productions of each applied treatment, avoiding any possible biases through the additional control of 100 randomly selected olives from each of the samples. There is an improvement in the set of physical characteristics of the olives with the treatment that provides amino acids and extra potassium based on amni acids. We analyzed the quality of the olive oil obtained from the production of each treatment by measuring the fatty acids, tocopherols and polyphenols contents. We also carried out an organoleptic tasting analysis following the rules of the International Olive Committee (IOC). We observed an improvement with regard to the rest of treatments in the pomological parameters of the olives when applying the potassium and amino acid biostimulant, while the quality of the oils was not affected by the type of fertilization applied in each treatment.This work was funded by Project AICO/2017/047.

Sauvé-Kapandji and reverse Sauvé-Kapandji procedures for treating chronic longitudinal radioulnar dissociation with capitellum fracture

Almost all reported cases of longitudinal radioulnar dissociation have involved fracture of the radial head, rupture of the interosseous membrane, and disruption of the distal radioulnar joint, although unusual patterns of Essex-Lopresti injury have also been described. To our knowledge, this is the first report of a chronic Essex-Lopresti variant including fracture of the capitellum. A displaced capitellum fracture must alert to the possibility of longitudinal radioulnar dissociation, even without concomitant radial head fracture or symptoms at the forearm and ulnar wrist. Successful mid-term results can be achieved by treating malunion of humeral condyle and proximal migration of the radius with simultaneous Sauvé-Kapandji procedure at the wrist and reverse Sauvé-Kapandji at the elbow.Essex-Lopresti lezyonlarının nadir görülen bazı atipik formları tanımlanmış olsa da, literatürde bildirilen longitudinal radioulnar instabilite olgularında genellikle radius başı kırığı ve proksimal ve distal radioulnar eklemlerde yaralanma söz konusudur. Bu çalışmada kapitellum kırığı ile birlikte Essex- Lopresti lezyonu olan bir hastayı bildiriyoruz. Olgumuzda el bileğinde Sauvé-Kapandji ve dirsekte ters Sauvé-Kapandji tekniklerinin kombine olarak uygulanması ile orta vadede başarılı sonuçlar alınmıştır. El bileği ve önkol yakınması olmasa bile deplase kapitellum kırıklı hastalarda longitudinal radioulnar instabilite akla getirilmelidir

Effect of hot-water treatments above 50 ºC on grapevine viability and survival of Petri disease pathogens

[EN] Rootstocks (41 B Mgt., 140 Ruggeri, 161-49 Couderc, 1103 Paulsen and 110 Richter) and scion/rootstock combinations (Bobal/1103 P, Merlot/110 R, Tempranillo/110 R and Tempranillo/161-49 C) were hot-water treated (HWTed) at 50, 51, 52. 53, or 54 degrees C for three periods: 30, 45 or 60 min. Four groups of 10 cuttings were treated for each temperature and time, and four additional groups of 10 untreated cuttings were prepared as controls. At the end of the growing season, cutting sprouting and shoot weight were evaluated. In a second experiment, healthy cuttings of '110 R' rootstock were vacuum-inoculated with conidial suspensions (10(6) conidia mL(-1)) of one isolate of either Phaeomoniella chlamydospora or Phaeoacremonium aleophilum. These cuttings were subjected to the treatments indicated above. Four groups of 10 cuttings were treated for each temperature, time and isolate, with their respective controls. Isolations were made immediately after the treatments and at the end of the growing season, when cutting sprouting and shoot weight were evaluated. Results demonstrated that it is possible to hot-water treat grapevine planting material in Spanish nurseries using protocols with temperatures of up to 50 degrees C. HWTs at 53 degrees C are able to eliminate Pa. chlamydospora completely and Strongly reduce the re-isolation of Pm. aleophilum from grapevine wood. These findings will contribute to the development of an effective control for Petri disease in grapevine propagating material in Spanish grapevine nurseries.This research was financially supported by the Projects AGL2006-11884-C04-01 (Ministerio de Educacion y Ciencia, Spain) and TRT2006-00033-00-0 and RTA2007-00023-C04-03 (Programa Nacional de Recursos y Tecnologias Agrarias, Ministerio de Educacion y Ciencia, Spain).

Changes produced by the application of biostimulants on almond rootstocks properties during the nursery process

[EN] During the last ten years we have assisted to the consolidation of the almond crop that has remarkably increased its cultivation area causing a high demand for both plants and products related to growth stimulation. Accordingly, in the present work we aim to study the changes produced by the contribution of two biostimulants (humic and fulvic acids or aminoacids) on the properties of almond tree rootstocks. This kind of studies are of interest to the nursery cultivation industry where rapid growth of trees and good adaptation to their cultivation environment are required. Plants' radicular and vegetative systems responded differently according to the rootstock selection. The fastest and vigorous vegetative development was observed in GN rootstock whereas GF 677 showed the greatest number of main roots and RP-R of secondary roots. Differences on antioxidant activity and phenol content have also been found between rootstocks. All the tested samples were found to have a high antioxidant power and a high phenol content but GN stood out in this regard over the other rootstocks under study. The efficiency of the biostimulants applied has been verified. Both biostimulants promoted the development of the aerial part of the trees but biostimulant 2 did it to a greater extent. Biostimulant 1 was able to duplicate the number of main roots in RP-R and during the first year of study, biostimulant 2 originated an increase of the weight of the root system by 26.44% for RP-R, 16.93% for GF 677 and 48.00% for GN. In view of these results, synthetic chemical fertilizers can be at least partially replaced by biostimulants.Mondragón-Valero, A.; Malheiro, R.; Salazar Hernández, DM.; Pereira, JA.; López- Cortés, I.

Wheelchair collaborative control for disabled users navigating indoors.

https://v2.sherpa.ac.uk/id/publication/12586Objective: Mobility is of key importance for autonomous living. Persons with severe disabilities may be assisted by robotic wheelchairs when manual control is not possible. However, these persons should contribute to control as much as they can to avoid loss of residual skills and frustration. Traditionally, wheelchair shared control approaches either give control to person or robot depending on the situation. Methods and materials: We propose a new shared control technique where robot and person contribute simultaneously to control. Their commands are weighted according to their respective local efficiencies and then combined via a reactive navigation strategy. Thus, assistance adapts to the user's needs. We refer to this approach as collaborative control. Results: Collaborative control was tested in a home environment in Fondazione Santa Lucia (Rome) by 18 volunteers presenting different degrees of physical and cognitive disability. All of them successfully finished a complex test path with assistance. Both users and caregivers' opinion on the system was very positive. Acceptance was very good according to the psychosocial impact of assistive devices scale. Conclusions: Collaborative control adapts to the person's needs and assists him/her when necessary, locally compensating any problem related to specific disabilities. An ANOVA returned a p-value of 0.016, meaning that there is significant improvement in task performance when collaborative control is used. (C) 2011 Elsevier B.V. All rights reserved

Biomechanical Finite Element Method Model of the Proximal Carpal Row and Experimental Validation

This research was funded by the Ministry of Education Grants DPI2017-83859-R, EQC2018-004508-P, and UNGR15-CE-3664; Ministry of Health Grants DTS15/00093 and PI16/00339; and Junta de Andalucia Grants, B-TEP-026-UGR18, IE2017-5537, P18-RT-1653, PI-0107-2017, and PIN-0030-2017.The Finite Element Method (FEM) models are valuable tools to create an idea of the behavior of any structure. The complexity of the joints, materials, attachment areas, and boundary conditions is an open issue in biomechanics that needs to be addressed. Scapholunate instability is the leading cause of wrist pain and disability among patients of all ages. It is needed a better understanding of pathomechanics to develop new effective treatments. Previous models have emulated joints like the ankle or the knee but there are few about the wrist joint. The elaboration of realistic computational models of the carpus can give critical information to biomedical research and surgery to develop new surgical reconstructions. Hence, a 3D model of the proximal carpal row has been created through DICOM images, making a reduced wrist model. The materials, contacts, and ligaments definition were made via open-source software to extract results and carry on a reference comparison. Thus, considering the limitations that a reduced model could carry on (unbalanced forces and torques), the stresses that result in the scapholunate interosseous ligament (SLIL) lead us to a bones relative displacement, which support the kinematics hypothesis in the literature as the distal carpal row moves as a rigid solid with the capitate bone. Also, experimental testing is performed, successfully validating the linear strength values of the scapholunate ligament from the literature.Ministry of Education Grants DPI2017-83859-R EQC2018-004508-P UNGR15-CE-3664Ministry of Health Grants DTS15/00093 PI16/00339Junta de Andalucia B-TEP-026-UGR18 IE2017-5537 P18-RT-1653 PI-0107-2017 PIN-0030-201
