BS-SEM evaluation of the tisular interactions between cortical bone and calcium-phosphate covered titanium implants

The improvement of the reliability of the contact between the osseous tissues and the implant materials has been tested by recovering the metallic implants with ceramic materials, usually calcium phosphates. In our study, the calcium phosphate recovering layers were deposited by means of a pulsed-laser deposition technique. Our aim was to to evaluate the tissue interactions established between cortical bone and titanium implants covered by five different layers, ranging from amorphous calcium phosphate to crystalline hydroxyapatite, obtained by altering the parameters of the laser ablation process. The surgical protocol of the study consisted in the simultaneous implantation of the five types of implants in both the tibial dyaphisis of three Beagle dogs, sacrificed respectively one, two and three months after the last surgical procedures. After the sacrifice, the samples were submitted to a scheduled procedure of embedding in plastic polymers without prior decalcification, in order to perform the ultrastructural studies: scanning microscopy with secondary and backscattered electrons (BS-SEM). Our observations show that both in terms of the calcified tissues appearing as a response to the presence of the different coatings and of time of recovering, the implants coated with crystalline calcium phosphate layers by laser ablation present a better result than the amorphous-calcium-phosphate-coated implants. Moreover, the constant presence of chondroid tissue, related with the mechanical induction by forces applied on the recovering area, strongly suggests that the mechanisms implied in osteointegration are related to endomembranous, rather than endochondral ossification processes

Poverty and marginalisation : challenges to poor women's leadership in urban India

This article examines the women's quota at the local governance level in urban India, using several case studies of women municipal councillors, to question the evidently low numbers of poor and marginalised women amongst them. It examines issues of class, caste, and religion that have a direct impact on the access of poor women to quotas reserved for them at the local government level. The objective of this work is to draw attention to the specific ways in which women are constrained at the pre-election stage, resulting in an elite capture of the women's quota in India, indicating the need for further research and study on this issue.

THE ROLE OF MINERAL NUTRITION ON YIELDS AND FRUIT QUALITY IN GRAPEVINE, PEAR AND APPLE

ABSTRACT Fertilization of temperate fruit trees, such as grapevine ( Vitis spp.), apple ( Malus domestica), and pear ( Pyrus communis) is an important tool to achive maximum yield and fruit quality. Fertilizers are provided when soil fertility does not allow trees to express their genetic potential, and time and rate of application should be scheduled to promote fruit quality. Grapevine berries, must and wine quality are affected principally by N, that regulate the synthesis of some important compounds, such as anthocyanins, which are responsible for coloring of the must and the wine. Fermenation of the must may stop in grapes with low concentration of N because N is requested in high amount by yeasts. An N excess may increase the pulp to peel ratio, diluting the concentration of anthocyanins and promoting the migration of anthocyanins from berries to the growing plant organs; a decrease of grape juice soluble solid concentration is also expected because of an increase in vegetative growth. Potassium is also important for wine quality contributing to adequate berry maturation, concentration of sugars, synthesis of phenols and the regulation of pH and acidity. In apple and pear, Ca and K are important for fruit quality and storage. Potassium is the most important component of fruit, however, any excess should be avoided and an adequate K:Ca balance should be achieved. Adequate concentration of Ca in the fruit prevents pre- and post-harvest fruit disorders and, at the same time, increases tolerance to pathogens. Although N promotes adequate growth soil N availability should be monitored to avoid excessive N uptake that may decrease fruit skin color and storability.

Local perception and use of the multifunctionality of water tanks in two villages of Tamil Nadu, South India

Using data from free listings and a survey in two villages of Tamil Nadu, India, we discuss local perceptions and uses of water tanks, a traditional irrigation infrastructure. We hypothesize that both farmers and nonfarmers perceive and use water tanks for purposes other than irrigation. We found that informants recognized the importance of water tanks for irrigation, but also acknowledged other socioeconomic uses and ecological functions. Marginal sectors (i.e., Scheduled Castes) use tank resources in more diverse ways than other sectors of the population. Findings are relevant for development. International organizations working on the revival of water tanks aim to transfer water management to farmers for the purpose of irrigation. By recognizing that tanks benefit people other than farmers and in ways other than providing irrigation water, organizations working on tank rejuvenation could achieve a more equitable management of tank resources.

Induction chemoradiation in stage IIIA/N2 non-small-cell lung cancer: a phase 3 randomised trial.

BACKGROUND: One of the standard options in the treatment of stage IIIA/N2 non-small-cell lung cancer is neoadjuvant chemotherapy and surgery. We did a randomised trial to investigate whether the addition of neoadjuvant radiotherapy improves outcomes. METHODS: We enrolled patients in 23 centres in Switzerland, Germany and Serbia. Eligible patients had pathologically proven, stage IIIA/N2 non-small-cell lung cancer and were randomly assigned to treatment groups in a 1:1 ratio. Those in the chemoradiotherapy group received three cycles of neoadjuvant chemotherapy (100 mg/m(2) cisplatin and 85 mg/m(2) docetaxel) followed by radiotherapy with 44 Gy in 22 fractions over 3 weeks, and those in the control group received neoadjuvant chemotherapy alone. All patients were scheduled to undergo surgery. Randomisation was stratified by centre, mediastinal bulk (less than 5 cm vs 5 cm or more), and weight loss (5% or more vs less than 5% in the previous 6 months). The primary endpoint was event-free survival. Analyses were done by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00030771. FINDINGS: From 2001 to 2012, 232 patients were enrolled, of whom 117 were allocated to the chemoradiotherapy group and 115 to the chemotherapy group. Median event-free survival was similar in the two groups at 12·8 months (95% CI 9·7-22·9) in the chemoradiotherapy group and 11·6 months (8·4-15·2) in the chemotherapy group (p=0·67). Median overall survival was 37·1 months (95% CI 22·6-50·0) with radiotherapy, compared with 26·2 months (19·9-52·1) in the control group. Chemotherapy-related toxic effects were reported in most patients, but 91% of patients completed three cycles of chemotherapy. Radiotherapy-induced grade 3 dysphagia was seen in seven (7%) patients. Three patients died in the control group within 30 days after surgery. INTERPRETATION: Radiotherapy did not add any benefit to induction chemotherapy followed by surgery. We suggest that one definitive local treatment modality combined with neoadjuvant chemotherapy is adequate to treat resectable stage IIIA/N2 non-small-cell lung cancer.

Soldiers in a stingless bee: work rate and task repertoire suggest they are an elite force

The differentiation of workers into morphological subcastes (e.g., soldiers) represents an important evolutionary transition and is thought to improve division of labor in social insects. Soldiers occur in many ant and termite species, where they make up a small proportion of the workforce. A common assumption of worker caste evolution is that soldiers are behavioral specialists. Here, we report the first test of the "rare specialist" hypothesis in a eusocial bee. Colonies of the stingless bee Tetragonisca angustula are defended by a small group of morphologically differentiated soldiers. Contrary to the rare specialist hypothesis, we found that soldiers worked more (+34%-41%) and performed a greater variety of tasks (+23%-34%) than other workers, particularly early in life. Our results suggest a "rare elite" function of soldiers in T. angustula, that is, that they perform a disproportionately large amount of the work. Division of labor was based on a combination of temporal and physical castes, but soldiers transitioned faster from one task to the next. We discuss why the rare specialist assumption might not hold in species with a moderate degree of worker differentiation.

Aortic Annulus Stabilization Technique for Rapid Deployment Aortic Valve Replacement.

NlmCategory="UNASSIGNED">Rapid deployment aortic valve replacement (RDAVR) with the use of rapid deployment valve systems represents a smart alternative to the use of standard aortic bioprosthesis for aortic valve replacement. Nevertheless, its use is still debatable in patients with pure aortic valve regurgitation or true bicuspid aortic valve because of the risk of postoperative paravalvular leak. To address this issue, an optimal annulus-valve size match seems to be the ideal surgical strategy. This article describes a new technique developed to stabilize the aortic annulus and prevent paravalvular leak after RDAVR. To confirm the feasibility, this technique was performed in six patients with severe symptomatic aortic stenosis who were scheduled to undergo aortic valve replacement at our center. All patients survived surgery and were discharged from the hospital. There were no new intracardiac conduction system disturbances observed, and a permanent pacemaker implantation was not required in any of the patients. The intraoperative and postoperative echocardiogram confirmed successful positioning of the valve, and no paravalvular leak was observed. In this preliminary experience, RDAVR through a full sternotomy or an upper hemisternotomy approach with the use of aortic annulus stabilization technique was safe, and no leak was observed. Future studies on large series of patients are necessary to confirm the safety and effectiveness of this technique in preventing paravalvular leak in patients with true bicuspid aortic valves or pure aortic regurgitation.

Gestió dels residus alimentaris municipals procedents de les activitats comercials del municipi de Montmeló per tal de reduir, reutilitzar i reciclar-los

En el present treball es proposa com lluitar contra el malbaratament alimentari que es genera al llarg de tota la cadena alimentària, sent aquest degut a causa d'una planificació poc adequada. L'objectiu principal és planificar i implantar un sistema de gestió per tal de recuperar l'excedent alimentari que es genera als comerços i les indústries del municipi de Montmeló, elaborant així un protocol per tal de poder redistribuir aquest aliment als sectors de la població en situacions econòmiques més precàries. Com a objectius secundaris, es pretén conscienciar, fomentar i potenciar el treball en xarxa entre els diferents agents implicats, com ara: la ciutadania, les entitats socials (Càritas Parroquial Montmeló), sector privat (establiments alimentaris del municipi, mercat municipal, indústries del sector alimentari) i el sector públic (departament de serveis socials, medi ambient, comerç i brigada municipal). A l'hora de planificar i implantar un sistema de gestió per tal de recuperar l'excedent alimentari, s'ha analitzat i valorat el camí que hi realitza, des d'on es genera fins al beneficiari final. Aquest s'ha gestionat per etapes, en les que s'han identificat els generadors, el tipus i quantitat d'aliment que malbaraten. S'ha proposat un nou sistema de recollida d'informació i les pautes que han de seguir per garantir el bon estat de l'aliment com: una taula de conservació, un protocol de funcionament, un document d'entrega i una fitxa de control de les condicions d'higiene. Per tal d'assolir una bona coordinació entre totes les parts, s'han realitzat reunions conjuntes entre els generadors, serveis socials i Càritas on s'ha acabat signant un acord de col·laboració. Entre les conclusions més rellevants cal destacar que ha servit per establir un precedent d'aprofitament alimentari al municipi de Montmeló, aconseguint alimentar a un gran nombre de famílies amb greus problemes econòmics. A més s'ha arribat a disminuir la quantitat de residus generats, amb el conseqüent estalvi de recursos econòmics i materials on s'ha recuperat un total de 5.760 Kg d'aliments aptes pel consum.

The impact of adopting a CLIL approach on EFL learners reading skills in Catalonia school

En els últims anys, un gran nombre de docents i escoles han estat introduint programes AICLE a les escoles catalanes. A la majoria d’escoles, però, només s'ensenya anglès com a llengua estrangera, la qual cosa, limita les oportunitats d'estar en contacte amb la llengua estrangera en un context diferent. L’objectiu d'aquest estudi és analitzar si els infants milloren en les seves habilitats lectores i comprovar si existeix un avantatge significatiu respecte els alumnes que només estudien anglès com a llengua estrangera. L’estudi empíric que us presento a continuació, compara els resultats obtinguts en dues proves de comprensió lectora. A les proves hi van participar dos grups d’alumnes de cinquè de d’Educació Primària. Un dels grups seguia un programa AICLE (1 hora a la setmana i , a més aprenia anglès coma llengua estrangera); l’altre grup només estudiava anglès com a llengua estrangera. L'objectiu principal d'aquest projecte d'investigació és esbrinar si els programes AICLE tenen un impacte en les habilitats lectores en llengua anglesa dels alumnes. Així doncs, humilment intentaré contribuir a la literatura existent sobre els beneficis de l’AICLE.

Control remoto del robot ABB IRB 120 por tecnología Wifi

Durante toda la evolución de la tecnología, se han empleado aparatos interconexionados por cables. Los cables limitan la libertad de movimiento del usuario y pueden captar interferencias entre ellos si la red de cableado es elevada. Mientras avanzaba la tecnología inalámbrica, se ha ido adaptando al equipamiento electrónico a la vez que se iban haciendo cada vez más pequeños. Por esto, se impone la necesidad de utilizarlos como controles a distancia sin el empleo de cables debido a los inconvenientes que estos conllevan. El presente trabajo, pretende unificar tres tecnologías que pueden tener en el futuro una gran afinidad. · Dispositivos basados en el sistema Android. Desde sus inicios, han tenido una evolución meteórica. Se han ido haciendo cada vez más rápidos y mejores. · Sistemas inalámbricos. Los sistemas wifi o bluetooth, se han ido incorporando a nuestras vidas cada vez más y están prácticamente en cualquier aparato. · Robótica. Cualquier proceso de producción incorpora un robot. Son necesarios para hacer muchos trabajos que, aunque el hombre lo puede realizar, un robot reduce los tiempos y la peligrosidad de los procesos. Aunque las dos primeras tecnologías van unidas, ¿quién no tiene un teléfono con conexión wifi y bluetooth?, pocos diseños aúnan estos campos con la Robótica. El objetivo final de este trabajo es realizar una aplicación en Android para el control remoto de un robot, empleando el sistema de comunicación inalámbrico. La aplicación desarrollada, permite controlar el robot a conveniencia del usuario en un entorno táctil/teledirigido. Gracias a la utilización de simulador en ambos lenguajes (RAPID y Android), ha sido posible realizar la programación sin tener que estar presente ante el robot objeto de este trabajo. A través de su progreso, se ha ido evolucionando en la cantidad de datos enviados al robot y complejidad en su procesamiento, a la vez que se ha mejorado en la estética de la aplicación. Finalmente se usó la aplicación desarrollada con el robot, consiguiendo con éxito que realizara los movimientos que eran enviados con la tablet programada.
