Poultry litter is an important nutrient source in agriculture, although little information is available regarding its decomposition rate and nutrient release. To evaluate these processes, poultry litter (PL) was applied to the soil to supply 100, 200 and 300 kg ha-1 N contained in 4,953, 9,907 and 14,860 kg ha-1 PL, respectively. The litter bag technique was used to monitor the process of decomposition and nutrient release from the litter. These bags were left on the soil surface and collected periodically (after 15, 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330, and 365 days). The dry matter (DM) loss was highest (35 %) after the first 30 days of field incubation. The highest nutrient release occurred in the first 60 days on the field, when 40, 34, 91, and 39 %, respectively, of N, P, K, and Ca of the initial PL dry matter (4,860 kg ha-1) was already released to the soil. In absolute terms, these percentages represent 40, 23, 134, and 69 kg ha-1 of N, P, K, and Ca and these values doubled and tripled as the PL fertilization rates increased to 9,907 and 14,860 kg ha-1, respectively. After one year of field incubation, the residual contents in the litter were 27, 15, 18 and 30 % of the initial DM , and N, P and Ca, respectively. The release rate of K was the fastest and 91 % of the K had been released from the PL after 30 days of field incubation.

El objetivo de este artículo es demostrar la posibilidad de llegar también a la imagen platónica de l caverna desde el cine. En este sentido se puede hablar de referencias explícitas como en el caso de El conformista de B. Bertolucci o Shadowlands de R. Attenborough, si se tienen presentes las Crónicas de Narnia de C. S. Lewis- o The Picture of Dorian Gray -si se tiene presenta la novela de Oscar Wilde-, pero, en otras ocasiones, pese a que la influencia platónica no pueda ser demostrada, por ejemplo en The Truman Show, A Room with a View o Brideshead Revisited, podemos servirnos perfectamente de estas películas para guiar al público contemporáneo hacia aquella imagen platónica, ya que el mismo platón demuestra que se trata de una imagen aplicable y, en primer lugar, a su filosofía idealista.

The aim of this article is to prove the real possibility of travelling intellectually to the Platonic image of the cave from different films. In this sense, one can speak of explicit references as in The Conformist by B. Bertolucci or in Shadowlands by R. Attenborough -if one bears in mind the Chronicles of Narnia by C. S. Lewis- or The Picture of Dorian Gray ¿if one bears in mind the well-known O. Wilde¿s novel-, but, on other occasions, although the Platonic influence cannot be proved, for instance in The Truman Show, A Room with a View or Brideshead Revisited, one can perfectly think of these films in order to guide the contemporary audiences to that Platonic image, since Plato himself affirms that it deals with an image which can be easily applied and, in first place, to his idealistic philosophy.

Commençant par la compréhension du processus de prise de décisions en politique économique, puis par l'étude de la participation des Acteurs Sociaux (AS), pour aboutir à l'éclaircissement de leur rôle en politique économique. Le choix des AS correspond aux facteurs productifs :¦? Travail : Syndicat, Confédérations¦? Capital : Patronat, Groupes économiques¦? Ressources naturelles - inclus l'Economie clandestine¦? Esprit d'entreprise dans tous les AS¦Méthode : analyse institutionnelle, AS comme protagonistes. Contexte latino-américain et mondial (chapitre I), relation avec les Politiques (chapitre II), identification des positionnements face aux Politiques économiques (chapitre III). Etude sur deux périodes :¦1) Front National (FN) (1958-1986). Pacte de partis traditionnels pour l'obtention (non accomplie) de la paix et du développement. Objectif acquis via des politiques adéquates mais sans amélioration du domaine social (politique de revenu absente).¦En conséquence, développement des Cartels surpassant l'Intégration Andine. Echec des tentatives d'Ouverture précoce grâce aux Centrales syndicales (1977) aux Organisations patronales (1981), confirmant le bipartisme; crise de la dette sans cessations de paiements, ni décennie perdue (Colombie) ; développement des AS profitant d'absence de partis d'opposition.¦2) L'Ouverture (1989-2000) : Nouvelle Constitution avec amplifications de l'Etat, réformes financière, des échanges, sans sélectivité ni gradualité demandées par les AS. Emergence du blanchiment.¦Montée en puissance des Groupes économiques au détriment des Organisations patronales, (excepté les industriels), perte du lobbying syndical. Malgré des résultats positifs macro-économiques, les taux de chômage, secteur informel, et pauvreté, situent¦le pays au 2eme rang en concentration du revenu en Amérique latine et au 5eme rang mondial.¦Conclusion : les AS se sont mis en avant dans l'inflation (30% à 8%) et la dévaluation. Par contre, les taux d'intérêt et de change ont provoqué le crédit clandestin et la réévaluation avec ouverture aux importations ; pas de succès non plus sur le déficit fiscal ni la gestion des booms (café, drogues). La plupart des Politiques ont donc été décidées d'après la Banque centrale et le Ministère des finances confirmant la primauté du gouvernement sur les AS durant la période analysée.

Effective treatment of ovarian cancer depends upon the early detection of the malignancy. Here, we report on the development of a new nanostructured immunosensor for early detection of cancer antigen 125 (CA-125). A gold electrode was modified with mercaptopropionic acid (MPA), and then consecutively conjugated with silica coated gold nanoparticles (AuNP@SiO2), CdSe quantum dots (QDs) and anti-CA-125 monoclonal antibody (mAb). The engineered MPA|AuNP@SiO2|QD|mAb immunosensor was characterised using transmission electron microscopy (TEM), atomic force microscopy (AFM), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). Successive conjugation of AuNP@SiO2, CdSe QD and anti-CA-125 mAb onto the gold electrode resulted in sensitive detection of CA-125 with a limit of detection (LOD) of 0.0016 U mL(-1) and a linear detection range (LDR) of 0-0.1 U mL(-1). Based on the high sensitivity and specificity of the immunosensor, we propose this highly stable and reproducible biosensor for the early detection of CA-125.

We propose a method to obtain a single centered correlation with use of a joint transform correlator. We analyze the required setup to carry out the whole process optically, and we also present experimental results.
