Generation of 17-TW 23-fs pulses with a two-stage Ti : Sapphire amplifier at repetition rate 10 Hz

We have developed a two-stage Ti:sapphire amplifier system which can produce 17-TW/23-fs pulses at a repetition rate 10 MHz. A birefringent plate is used in the regenerative amplifier to alleviate gain narrowing, while an all-reflective cylindrical-mirror-based pulse stretcher and an acousto-optic programmable dispersive filter (AOPDF) are used to compensate for the higher order dispersion of the system.

Comparative investigations on the respiratory physiology of euryhaline gammarids with special reference to salinity adaptation. [Translation from: Helgolaender Wissenschaftliche Meeresuntersuchungen 23(4) 485-534, 1972.]

Members of the family Gammaridae are very closely interrelated. There arises the question as to how far they also differ amongst themselves through physiological characteristics. Comparative respiratory and physiological experiments were made on the five euryhaline species Gammarus locusta, G. oceanicus, G. salinus, G. zaddachi and G. duebeni. The respiratory measurements carried out within the framework of this experiment were occupied with the relationships between oxygen consumption and body size depending on salinity. They also had the object of determing the variations in metabolic intensity after an abrupt change in the salt content of the external medium, and to establish the period of time for the process of adaptation. As the experiments were carried out polarographically in a testing plant with continuous flow-through, and the method which was applied permitted continuous recording over prolonged intervals, there could also be carried out comparisons between metabolism at rest and under activity, and the alterations of oxygen consumption during the process of moulting could be measured.

Report of the PRA carried out at Obenge Beach, Kenya, June 23-26, 2000

This document contains the findings of the third Participatory Rural Appraisal (PRA) carried out on Obenge Beach in Kenya, from the 23rd to the 26th of June 2000, under the LVFRP. Its principal objectives were to develop base-line information on a Kenyan beach for the 3-beaches survey of the LVFRP.

Experimental culture of algal balls (Cladophora sauteri). Retention of original shape [Translation from: Bull.Jap.Soc.Phycol. Vol. 10, (1), p. 23-27, 1962]

It was on July 1960 when 10 algal balls were acquired for exhibition at Suma Aquarium, Kobe. Permission to remove the specimens from the Lake Akan Reserve was given by the National Nature Reserve Committee. Algal balls, as a rule, lose their natural beauty when they are kept in an ordinary tank for a certain length of time. In an effort to retain the natural beauty it was decided to exhibit them in culture. This paper summarises the findings of this experiments with Cladophora sauteri. The author concludes that serious consideration has to be given as to the intensity of light, the sunlight, the water temperature and the nutrition for algal balls in culture in order to retain the natural beauty and shape.

Some data on the content of organic carbon in rivers in the winter months. [Translation from: Gidrochim. Mat. 23, 36-38, 1955]

Observations are reported on the content of organic matter in the Moscow region in 1941. Some data is given on alkalinity, oxygen content and colourisation of the rivers.

Optical properties of the organic substances from aqueous humus surface waters. [Translation from: Gidrochim. Mat. 23, 31-35, 1955]

Dissolved organic matter, especially turf and peat, is repsonsible for the colouration of water. The reported study tried to determine the nature of the colouring agent or organic matter by the establishment of a relationship between the intensity of colouration and the total organic matter content. 44 waters from different sources were examined.

La reforma de las pensiones: Análisis económico de la Ley 23/2013

El siguiente Trabajo Fin de Grado analiza las particularidades de la “Ley 23/2013, de 23 de diciembre, reguladora del Factor de Sostenibilidad y del Índice de Revalorización del Sistema de Pensiones de la Seguridad Social”. El trabajo se centra principalmente en los dos componentes que constituyen la ley anteriormente citada, por un lado en el Factor de Sostenibilidad y por otro lado en el Índice de Revalorización de las Pensiones.

Erretiro pentsio kontributiboak 23/2013 legeak dakartzan aldaketen harira

Ezagun da pentsio sistema espainiarrak arazoak dituela. Arazo horiek, gainera, aspaldidanik datoz; badira 30 urte pentsioen jasangarritasunak kezka sortu zuela Estatu espainiarrean. Kezka horiek Gizarte Segurantzaren oreka ekonomikoan eta epe ertain eta luzera dituen prestazio-konpromezuak betetzeko gaitasunean – edo gaitasun ezean – oinarritu dira, batik bat. Alderdi ekonomikoan, sistema espainiarra moteldu dute krisi ekonomikoak eta lan merkatuaren egoerak. Alderdi demografikoan, sistema espainiarra ahuldu du biztanleria zahartzeak, jaiotza-tasa baxuak eta baby boom belaunaldia erretirora heltzeak. Azkenik, alderdi estrukturalean, banaketa sistemaren beraren izaerak tenkatu du korda.
