L’aspiració de trobar una eina que pugui ajudar a identifi car els papers atenent les sevescaracterístiques sorgeix a fi nal segle XVIII amb les primeres descripcions de les filigranespapereres i va prenent cos al segle XIX com a ciència auxiliar de la codicologia.Des de les últimes dècades del segle XX, les filigranes han anat adquirint un interès creixententre els restauradors de document gràfi c —com una eina més per a la presa de decisions i pera la valoració del procés de restauració— i entre els documentalistes, historiadors, museòlegsi bibliòfils —per a la datació i autenticació de les obres— i, fins i tot, en investigacionspolicials i jurídiques per aclarir algun fet delictiu. No obstant això, durant aquests 150 anys, l’estudi del paper a través de les filigranes papereres a Espanya no ha experimentat cap avenç significatiu pel que fa als mètodes i procediments seguits per a l’obtenció i gestió deles dades. En l’àmbit europeu, encara que a partir dels anys 90 sorgeixen noves propostesd’estudi, aquestes limiten la investigació a l’anàlisi de la filigrana sense assolir una visió global del plec sortit de la forma.

Els invents del teléfon i la televisió i la feina deis carters van popularitzar un treball de formació anomenat usualment ensenyament per correspondencia. Amb aixb es tractava d'eixamplar I'educació per a tothom qui no pogués seguir el ritme de I'escola oficial. Ara, I'ús de la informatica ens permet anar més Iluny i parlem d'educació a distancia i telematica educativa (vegeu el monografic TE, 16). En particular, fer matematiques a distancia té com a objectiu facilitar I'accés a processos formatius a una part de la població que, d'altra forma, tindria dificultats per fer-ho: malalts, persones grans, interns a les presons, etc.

AIMS: The objectives of this study were to analyse (a) the distribution of risky single-occasion drinking (RSOD) among 19-year-old men in Switzerland and (b) to show the percentage of all alcohol consumption in the form of RSOD. METHODS: The study was based on a census of Swiss francophone 19-year-old men consecutively reporting for processing. The study was conducted at Army Recruitment Center. The participants were 4116 recruits consecutively enrolling for mandatory army recruitment procedures between 23 January and 29 August in 2007. The measures were alcohol consumption measured in drinks of approximately 10 g of pure alcohol, number of drinking occasions with six or more drinks (RSOD) in the past 12 months and a retrospective 1 week drinking diary. RESULTS: 264 recruits were never seen by the research staff, 3536 of the remaining 3852 conscripts completed a questionnaire which showed that 7.2% abstained from alcohol and 75.5% of those drinking had an RSOD day at least monthly. The typical frequency of drinking was 1-3 days per week on weekends. The average quantity on weekends was about seven drinks, 69.3% of the total weekly consumption was in the form of RSOD days, and of all the alcohol consumed, 96.2% was by drinkers who had RSOD days at least once a month. CONCLUSION: Among young men, RSOD constitutes the norm. Prevention consequently must address the total population and not only high-risk drinkers.

En aquest article es presenta una anàlisi de les dades sobre alumnat segons la nacionalitat per al període comprès entre els cursos acadèmics 2000/2001 i 2006/2007 per al total del Principat, i amb més detall, per al curs 2007/2008 a la Delegació Territorial de Girona lliurades pel Departament d'Educació de la Generalitat de Catalunya. Entre els principals resultats, destaquem l'increment d'alumnes a causa de l'augment de la fecunditat, creixement que es concentra en els primers cicles educatius, així com de la immigració, que n'és conseqüència directa. S'ha apuntat també com la permanència en el cicle formatiu és preocupantment diferencial per nacionalitats. D'altra banda, s'ha vist clarament com la titularitat del centre té un paper fonamental en la segregació de la població per nacionalitat, però, al mateix temps, com la planificació en aquesta matèria pot corregir aquest fet, amb independència del nombre d'immigrants estrangers residents al municipi.

El treball que es presenta gira a l'entorn de la classe teòrica presencial, dissenyada segons les possibilitats d'aquesta classe quan es planteja per a un nombre elevat d'alumnes i es pretén la màxima implicació de l'estudiant. Analitza l'assistència a classe, el tipus de classe teòrica que s'imparteix i els resultats de les iniciatives preses per incentivar la participació activa. Els resultats demostren que els plantejaments didàctics són globalment adients en aquest context, fet que es reflecteix en la bona acceptació per part de l'alumne de les iniciatives proposades i en la millora notable del rendiment acadèmic, objectiu primordial del projecte REDICE-06 titulat Deconstrucció/construcció de l'ensenyament presencial, del qual forma part.

Background: Treatment of depression, the most prevalent and costly mental disorder, needs to be improved. Non-concordance with clinical guidelines and non-adherence can limit the efficacy of pharmacological treatment of depression. Through pharmaceutical care, pharmacists can improve patients' compliance and wellbeing. The aim of this study is to evaluate the effectiveness and costeffectiveness of a community pharmacist intervention developed to improve adherence and outcomes of primary care patients with depression. Methods/design: A randomized controlled trial, with 6-month follow-up, comparing patients receiving a pharmaceutical care support programme in primary care with patients receiving usual care. The total sample comprises 194 patients (aged between 18 and 75) diagnosed with depressive disorder in a primary care health centre in the province of Barcelona (Spain). Subjects will be asked for written informed consent in order to participate in the study. Diagnosis will be confirmed using the SCID-I. The intervention consists of an educational programme focused on improving knowledge about medication, making patients aware of the importance of compliance, reducing stigma, reassuring patients about side-effects and stressing the importance of carrying out general practitioners' advice. Measurements will take place at baseline, and after 3 and 6 months. Main outcome measure is compliance with antidepressants. Secondary outcomes include; clinical severity of depression (PHQ-9), anxiety (STAI-S), health-related quality of life (EuroQol-5D), satisfaction with the treatment received, side-effects, chronic physical conditions and sociodemographics. The use of healthcare and social care services will be assessed with an adapted version of the Client Service Receipt Inventory (CSRI). Discussion: This trial will provide valuable information for health professionals and policy makers on the effectiveness and cost-effectiveness of a pharmaceutical intervention programme in the context of primary care. Trial registration: NCT00794196

Scintillation counting is one of the most important developments in the application of radioisotopes to procedures needed by scientists, physicians, engineers, and technicians from many diverse discipline for the detection and quantitative measurement of radioactivity. In fact, Scintillation is the most sensitive and versatile technique for the detection and quantification ofradioactivity. Particularly, Solid and Liquid scintillation measurement are,nowadays, standard laboratory methods in the life-sciences for measuringradiation from gamma- and beta-emitting nuclides, respectively. Thismethodology is used routinely in the vast majority of diagnostic and/or researchlaboratories from those of biochemistry and biology to clinical departments.

Transmission electron microscopy is a proven technique in the field of cell biology and a very useful tool in biomedical research. Innovation and improvements in equipment together with the introduction of new technology have allowed us to improve our knowledge of biological tissues, to visualizestructures better and both to identify and to locate molecules. Of all the types ofmicroscopy exploited to date, electron microscopy is the one with the mostadvantageous resolution limit and therefore it is a very efficient technique fordeciphering the cell architecture and relating it to function. This chapter aims toprovide an overview of the most important techniques that we can apply to abiological sample, tissue or cells, to observe it with an electron microscope, fromthe most conventional to the latest generation. Processes and concepts aredefined, and the advantages and disadvantages of each technique are assessedalong with the image and information that we can obtain by using each one ofthem.
