Uusiutuvan energian käytön lisääntyminen lisää sähkön varastoinnin tarvetta. Litiumioniakku-jen on todettu olevan oivallisia keinoja varastoida sähköä esimerkiksi sähköautojen energian-lähteeksi. Tästä syystä akkujen kysyntä kasvaa nopeaa tahtia, jolloin nykyiset litiumlähteet ei-vät enää riitä tuottamaan tarpeeksi litiumia kasvavaan tarpeeseen. Tämän vuoksi litiumin tal-teenottoon tulee valjastaa uusia litiumin lähteitä, joiden hyödynnettävyys nykyisellä tekniikalla on pienen litiumkonsentraation ja muiden alkali- ja maa-alkalimetallien läsnäolon takia vaikeaa. Tällä hetkellä litiumia otetaan talteen eniten korkean litiumpitoisuuden luonnon suolajärvistä. Nykyisin käytössä oleva litiumin erotusprosessi on hidas ja sen käyttö pienten litiumkonsent-raatioiden suola-altailla on kannattamatonta. Tehokkaampana talteenottomenetelmänä luonnon suolajärvillä nähdään litiumin selektiivinen uutto ionisilla nesteillä. Menetelmä on todettu toi-mivaksi suolajärvillä, joilla on matala litiumkonsentraatio. Uusien suolajärvien käyttöönotto ei ratkaise kaikkia litiumin talteenottoon liittyviä ongelmia, sillä suolajärvet ovat alttiita ilmastonmuutokselle, eikä niiden litiumvarannot ole ehtymättömät. Merien litiumvarantoja sen sijaan pidetään lähes ehtymättöminä. Litiumin talteenotto meristä on mahdollista ionisia nesteitä ja membraaneja hyödyntävällä elektrodialyysilaitteistolla, jolla litiumia voidaan ottaa talteen myös hyvin pienistä pitoisuuksista. Lisäksi on mahdollista, että litiumin talteenottoon yhdistetään juomaveden valmistus. Tällainen vedenpuhdistusprosessi olisi myös hyvä kestävän kehityksen näkökulmasta.

Constantly making efforts to strengthen reading habits in children from their earliest years of life, a process in which the family is established as the primary basis for the child to achieve the taste and interest in books. The school as being key to education supports and strengthens the skills taught in the home, with the help of technologies such as computers, disk reading, television, among other means, by which (as) children (as) found a door of communication with the outside world and everything around them. The children's library tends to use these technological means to attract children to reading, generating and taste for the various information resources, which over time will become a habit.This research is based on the "Contribution of the Library Miriam Alvarez Brenes and family in the formation of reading habits of children of the community of Garden I and II University in Heredia, through advocacy, in 2007 "

Cómo los proyectos deben ir de la mano de un plan de acción concretable que esté acorde con los parámetros básicosconceptuales, fruto de la reflexión del papel que debe cumplir una biblioteca infantil como movilizadora social dentro del ámbito de la sociedad actual, es parte de la temática de la siguiente ponencia.La Escuela de Bibliotecología, Documentación e Información de la Universidad Nacional de Costa Rica, me solicitó explicara un poco como desde nuestra experiencia estamos concretando los procesos de planificación que se deben llevar a cabo para formular y crear un proyecto de extensión comunitaria de una biblioteca infantil.Es importante tener en cuenta el contexto en el qué se sitúa un proceso de planificación y por eso a esta intervención se le ha agregado el título “Bases para la creación de una biblioteca infantil acorde a los retos de la sociedad actual.El concepto de la sociedad actual de la información refleja bastante bien, desde mi punto de vista, los elementos básicos de nuestro entorno social.La sociedad enfrenta un incremento y difusión de la información que dió lugar al término de “sociedad de la información” posteriormente denominada como “sociedad del conocimiento”.Este cambio de terminología lo provocó el hecho que no se trata solo de informarse, sino que es necesario un proceso tanto individual como colectivo de tratamiento de esta información para convertirla en conocimiento. Casi de inmediato comenzamos a percibir que el acceso a lainformación no era suficiente.

To evaluate the use of optical and nonoptical aids during reading and writing activities in individuals with acquired low vision. This study was performed using descriptive and cross-sectional surveys. The data collection instrument was created with structured questions that were developed from an exploratory study and a previous test based on interviews, and it evaluated the following variables: personal characteristics, use of optical and nonoptical aids, and activities that required the use of optical and nonoptical aids. The study population included 30 subjects with acquired low vision and visual acuities of 20/200-20/400. Most subjects reported the use of some optical aids (60.0%). Of these 60.0%, the majority (83.3%) cited spectacles as the most widely used optical aid. The majority (63.3%) of subjects also reported the use of nonoptical aids, the most frequent ones being letter magnification (68.4%), followed by bringing the objects closer to the eyes (57.8%). Subjects often used more than one nonoptical aid. The majority of participants reported the use of optical and nonoptical aids during reading activities, highlighting the use of spectacles, magnifying glasses, and letter magnification; however, even after the use of these aids, we found that the subjects often needed to read the text more than once to understand it. During writing activities, all subjects reported the use of optical aids, while most stated that they did not use nonoptical aids for such activities.

Pregnant women have a 2-3 fold higher probability of developing restless legs syndrome (RLS - sleep-related movement disorders) than general population. This study aims to evaluate the behavior and locomotion of rats during pregnancy in order to verify if part of these animals exhibit some RLS-like features. We used 14 female 80-day-old Wistar rats that weighed between 200 and 250 g. The rats were distributed into control (CTRL) and pregnant (PN) groups. After a baseline evaluation of their behavior and locomotor activity in an open-field environment, the PN group was inducted into pregnancy, and their behavior and locomotor activity were evaluated on days 3, 10 and 19 of pregnancy and in the post-lactation period in parallel with the CTRL group. The serum iron and transferrin levels in the CTRL and PN groups were analyzed in blood collected after euthanasia by decapitation. There were no significant differences in the total ambulation, grooming events, fecal boli or urine pools between the CTRL and PN groups. However, the PN group exhibited fewer rearing events, increased grooming time and reduced immobilization time than the CTRL group (ANOVA, p<0.05). These results suggest that pregnant rats show behavioral and locomotor alterations similar to those observed in animal models of RLS, demonstrating to be a possible animal model of this sleep disorder.
