first_img Facebook Comments Costa Rica’s solemn Holy Week processions are a sight to behold, no matter what your religion. Never attended a Good Friday procession – or have a few years gone by since you last took one in? Andrés Madrigal captures the sights, sounds and elaborate pageantry of the 2016 downtown San José event in the video below.Most Costa Rican dioceses will hold processions on Good Friday and on Easter Sunday.

first_imgComcast is looking to expand their Xfinity services to not only include video, phone, and broadband Internet, but home security as well. After using Dallas as their test market, the company announced this week that it is now prepared to offer the service in six additional cities including Philadelphia, Portland, Jacksonville, Sarasota/Naples, Chattanooga and Nashville. The service will not only include 24/7 professional monitoring in addition to police and fire alarm protection, but will give consumers the ability to adjust digital thermostats, turn lights on/off, and watch secure live streaming video from wireless cameras while outside of the home.Many of the remote security controls offered through the service as well as the live streaming video will be available through a web portal as well as through the new Xfinity Security App for the iPhone which is available as a free download through the iTunes App Store.AdChoices广告Comcast is leveraging Xfinity broadband to bring additional services to home security including access to widgets through a tablet-like touch screen that includes access to weather, news, traffic and sports scores. Customers with Xfinity Voice will even be able to listen to voicemail through an app on the security interface. Additional features include real-time email and text alerts when doors open or close or when motion detectors detect activity inside or outside the home. Battery and cellular backup is also available to keep the system up and running in the event of a power outage.The Xfinity Home Security Preferred Package is currently being offered for as low as $39.95 a month.Other telecommunication companies looking to offer their own home security service include Verizon which announced its Home Monitoring and Control service at CES in January. A trial of the service is currently available to broadband customers in New Jersey.via Comcast.last_img

first_imgDes virus pour mimer la complexité de la natureDes scientifiques et ingénieurs américains se sont servis de virus pour créer de toutes pièces des structures complexes. Selon une étude publiée hier, ce type de procédé pourrait permettre de mettre au point de nouveaux matériaux.Depuis toujours, l’homme cherche à imiter la nature. S’il était autrefois fasciné par les oiseaux qui volent et les poissons qui vivent sous l’eau, les scientifiques s’intéressent aujourd’hui à l’architecture complexe des molécules. Ils cherchent à s’en inspirer pour créer des biomatériaux innovants en mimant le vivant : un procédé appelé “biomimétisme”.”Nous sommes très curieux de comprendre comment la nature peut créer une multiplicité de structures et de fonctions à partir de simples briques de base, comme le collagène pour les animaux ou la cellulose pour les plantes”, explique Seung-Wuk Lee, un scientifique à la tête d’une équipe de chercheurs américains.Selon la façon dont s’orientent et s’agencent ses fibres, le collagène peut former les tissus transparents de la cornée, ceux colorés de la peau ou intervenir dans la formation des os, précise TV5monde. Une auto-organisation à différentes échelles qui surpasse en complexité ce que l’homme peut produire en utilisant des méthodes de fabrication traditionnelles, soulignent les scientifiques dans la revue Nature.Des structures connues dans la nature ou encore inéditesÀ lire aussiPourquoi l’eau des océans est-elle salée ?Ils ont donc utilisé directement des “matériaux” vivants pour parvenir à imiter la complexité de la nature. Ils ont eu recours à des virus de bactéries, les phages M13, comme outils de taille nanométrique. Conservés dans une solution salée où étaient plongées des lames de verre auxquelles ils pouvaient se fixer, ces phages filamenteux ont constitués trois types de films différents. Il a suffi pour cela de jouer sur la concentration de la solution, la proportion de virus qu’elle contenait et la vitesse à laquelle les lames de verre en étaient extraites.Chacun des trois films possédait des propriétés propres et des couleurs et une iridescence variées. Les uns étaient une alternance de bandes de filaments, les autres des rubans en hélice et des paquets de filaments hélicoïdaux ondulant en vagues pour les troisièmes. “Nous avons non seulement imité les structures biologiques, nous avons aussi découvert des structures qu’on n’avait vues ni dans la nature ni en laboratoire”, soulignent les chercheurs. Ils ont également réussi à faire croître des couches de cellules biologiques en prenant pour supports les films créés par les virus. Ce procédé pourrait donc être utilisé pour créer de nouveaux matériaux à base de cristaux liquides ou permettre de réparer les tissus biologiques.Le 21 octobre 2011 à 19:32 • Maxime Lambertlast_img

first_imgThe news from U.S. Secretary of Agriculture Sonny Perdue of trade mitigation including, most importantly to soy, Market Facilitation Program (MFP) payments and Agricultural Trade Promotion (ATP) program funding, is news welcomed by soy growers who have suffered from the ongoing ill effects of tariffs.“We recognize and are thankful that these funds will help offset the persisting damage from tariffs, as well as enable new market development through ATP,” said Davie Stephens, president of the American Soybean Association (ASA) and soybean grower from Clinton, Ky.Stephens reiterated, however, that the soybean industry needs open trade access, saying, “The key word from today’s announcement is “facilitation”: Trade assistance will only facilitate soy growers’ ability to farm, not make their losses whole or tariff woes disappear long term. Trade assistance will only help in the short term.”The 2019 MFP program under the Commodity Credit Corporation (CCC) Charter Act and administered by Farm Service Agency (FSA) will provide $14.5 billion in payments to producers, among them soy growers. Payments this year, however, will be based not on individual crops as in the past, rather on county-specific rates determined by, “long term distortion from tariff damage,” according to USDA.  That single-county rate will be multiplied by a farm’s total planted acreage for all eligible crops to determine payment so that planting decisions are not skewed, and eligible plantings cannot exceed total 2018 plantings. The first payments will begin in late July or early August after Farm Service Agency (FSA) crop reporting is completed July 15th. Second and third payments will be made in November and early January if conditions warrant, USDA has reported.An additional $100 million will be issued through the ATP to assist in developing new export markets on behalf of producers, along with Food Purchase and Distribution Program (FPDP) relief for other commodities.ASA appreciates the Administration’s effort to bridge the gap during this difficult time. However, a second round of financial support to offset farm losses is only a partial and temporary solution, and not a permanent solution for soy growers who have lost their number one export market since tariffs were implemented by the U.S. and then China in July, 2019.last_img
