[EN]Isocitrate Dehydrogenase (IDH) is a key enzyme in the Krebs cycle, being responsible for the production of one of the three CO2 molecules related to cellular respiration. In order to measure the potential CO2 production linked to the marine planktonic community we have adapted an enzymatic methodology. Preliminary results show that different proportions of autotrophs, heterotrophs and mixotrophs and their metabolic pathways, lead to different relationships between potential CO2 emission and potential O2 consumption during cellular respiration. Although more experiments need to be made, this methodology is leading to a better understanding of cellular respiration in marine samples and their impact on the food chain, vertical Carbon flux and the current sequestering capacity for anthropogenic CO2.

[EN]In the present study, natural spawning of a broodstock group of greater amberjack (Seriola dumerili) is described with regards to: date, number of spawns, and total number of eggs produced per spawn. Fish werecaught in 2011 in the Canary Islands, Gran Canaria (Canary Islands, Spain), and kept in captivity. At the end of May 2014, the broodstock group was formed by two females with a weight 9.81±1.08 kg, size 90.0±2.82cm, with oovocites > 800μ, and five males 9.46±2.04 kg, 86.75±5.43 cm, all fluent with sperm. Between the 1stof June and 18thof October 2014, a total of 25.60 million eggs were obtained in 23 spawns.

[EN]For this study, a total of 19 greater amberjack (Seriola dumerili) broodstock were used. Females with oocites bigger than 600μ, and fluent males with a mean weight of 10.72±1.22 kg, fameles, and 10.77±2.33 kg males. The experimental tanks were circular tanks of 40 m3 capacity. One of the tanks were not induced and the other two were with GnRHa, one with injections and the other by implants. Best results, in all parameters studied were with natural spawns, with a 84.37% of fertilization, 92.21% of viable eggs at 24 hours of spawn, 96.60% of hatching, 69.91% of larvae one day after hatching and 10.78% of 5 day life larvae.

[EN]The number of eggs obtained in natural spawning (25.60 million) is higher than those obtained by injections (12.9 million) and implants (10.5 million). The number of eggs per female was 12.80 million, in natural spawning, and 4.30 and 3.51 million, in induced with injections and implants, respectively. In number of eggs per spawn, significant differences was observed, between natural spawns (1.11 million), and induced spawning’s (0.44 and 0.21 millions, injected and implants respectively). Significant differences was also found, in number of eggs per Kg female/spawn, between natural spawning’s (56,700 eggs), injection induced (37,200 eggs) and implants (25,200 eggs).

[EN]The three males and three females of tank 2 were induced with EV-500μg GnRHa implants, one implant (500μg) was used for the females and half that doses for males. The first injection was on the 3rd of June and the last one spawning’s the 21st of October, a total of 37 injections and 29 spawns were obtained. The first implant was introduced the 20th of June, the last spawn was on the 16th of October of the implant set the 14th, a total of 17 implants and 38 spawns were obtained. The number of spawns per induction was significantly higher (P < 0.01) in implanted females, no significant differences were found in latency period which was of 43-44 hours.

[EN]Eighteen mature meagre (Argyrosomus regius) broodstock, born in captivity, were divided in 3 experimental groups in ratios of 3 ♀ and 3 ♂ each. One group was inducted by injections of hCG, the other with GnRHa and the last group with implants of GnRHa. In all three treatments all females responded positively to the hormonal treatment. Statistically differences were found, in the number of spawns per induction, of females induced with hCG with the GnRHa treatments. Latency period was longer in spawns from GnRHa implants, and showed statistically differences with the other two treatments.

[EN]In the present study, the effect of three different hormonal treatments were tested (GnRHA and hCG injected and GnRHa implanted), in meagre (Argyrosomus regius) broodstock born in captivity, and their production. The highest productions per kg of female and spawn: number of eggs, fertilized eggs, hatched larvae, and larvae 3 days old after hatching, corresponds to the treatment of GnRHa injected. The number of viable eggs, hatched eggs and larvae 3 days with GnRha injected was significantly different from those treated with hGC. No significant differences were observed in production per kg female and induction in the different hormonal treatments,

[EN]The best results in all quality parameters, were obtained in the spawns of the broodstock injected with GnRHa, having 98,7 + 1,4% of fertilized eggs, 62,24 ± 27,47 % viable eggs, 92,56 ± 17,19 % hatching and 92,73 ± 10,52 % 3 day old larvae after hatching. Percentage of viable eggs was lower in the spawns of the broomstick injected with hCG, and had significant differences when compared with GnRHa broodstock treatments. 3 day old larvae and hatchings, obtained from the broomstock injected with GnRHa showed significant differences to the rest of the hormonal treatments.

La importancia de la circulación de animales en la obra de Copi (desde aquellos que visitan a la mujer sentada en el cómic homónimo, hasta su protagonismo en la novela epistolar La ciudad de las ratas) cobra gran relevancia cuando se considera su producción dentro de la vía minoritaria propiamente kafkiana. El arte es una rata, como los rizomas, porque se construye como un periscopio que ve el mundo (lo concibe) a través de una lógica sincrético-transmutadora: opera sobre él, pero principalmente sobre la máquina antropogénica, invirtiéndolo, desarmándolo y rearmándolo. Este trabajo recorre la figura de la rata, su mirada y lenguaje, y recupera la noción de imaginación pop para pensar la refundación (constante) de los límites entre animal y humano que se da, principalmente, en La ciudad de las ratas

El proyecto de investigación que desarrollo en la tesis, se orienta a explicar la transformación espacial, simbólica, tecnológica, de función y uso de la vivienda en el Río de la Plata en las postrimerías del período colonial. Las reformas borbónicas fueron un conjunto de decisiones de alta política tendiente a consolidar el poder Ibérico en las colonias ante el dinámico avance del sistema capitalista Inglés, estableciendo la monarquía Española mecanismos para recuperar el control político, reforzar la coerción y permitir al poder ibérico una mejor apropiación de recursos. El espacio del Plata era apetecido por los portugueses, los británicos y el contrabando, la fragmentación de las unidades productivas con sus propios hinterland llevaron al régimen colonial a efectuar cambios en el sistema político económico, incorporando a Buenos Ayres al nuevo sistema comercial y paralelamente como elemento de control, fundó el Virreinato, la Real Audiencia, el Consulado. La monarquía trasladó a Buenos Ayres la burocracia administrativa. La estrategia de dominación española en el área y una necesidad geopolítica pautó el crecimiento económico de la oscura y remota aldea del imperio español "la aldea olvidada". Nació así un polo de intercambio mercantil, un foco de inmigración en un revitalizado espacio económico estructurando una nueva ciudad. En aquel contexto hubo fuertes migraciones internas y externas que generaron en el espacio urbano y en el interior del sistema social fuertes tensiones donde una elite en ascenso demandó cuotas crecientes del comercio y el poder; generó un uso intensivo del suelo urbano y una "nueva" estética arquitectónica, plasmada en el lenguaje formal del neoclasicismo. Estos aportes orientan y dan sustento teórico a otra visión de la historia, por lo tanto en el trabajo de tesis, aplicando las variables espaciales, patrón de asentamiento, uso y ocupación del suelo, forma de acumulación económica e identidad en el más amplio sentido del término, enriquecerán la investigación y facilitaran el entretejido de la red que permitirá, a través de la vivienda "leer" a los habitantes e interpretar el valor social de la casa. Por ello el proceso de investigación no es un simple proceso descriptivo sino es la suma de categorías analíticas que integradas permiten una visión significante de los hombres y mujeres que son objeto de nuestro interés.
