I. Foehn winds of southern California.
An investigation of the hot, dry and dust laden winds occurring in the late fall and early winter in the Los Angeles Basin and attributed in the past to the influences of the desert regions to the north revealed that these currents were of a foehn nature. Their properties were found to be entirely due to dynamical heating produced in the descent from the high level areas in the interior to the lower Los Angeles Basin. Any dust associated with the phenomenon was found to be acquired from the Los Angeles area rather than transported from the desert. It was found that the frequency of occurrence of a mild type foehn of this nature during this season was sufficient to warrant its classification as a winter monsoon. This results from the topography of the Los Angeles region which allows an easy entrance to the air from the interior by virtue of the low level mountain passes north of the area. This monsoon provides the mild winter climate of southern California since temperatures associated with the foehn currents are far higher than those experienced when maritime air from the adjacent Pacific Ocean occupies the region.

II. Foehn wind cyclo-genesis.
Intense anticyclones frequently build up over the high level regions of the Great Basin and Columbia Plateau which lie between the Sierra Nevada and Cascade Mountains to the west and the Rocky Mountains to the east. The outflow from these anticyclones produce extensive foehns east of the Rockies in the comparatively low level areas of the middle west and the Canadian provinces of Alberta and Saskatchewan. Normally at this season of the year very cold polar continental air masses are present over this territory and with the occurrence of these foehns marked discontinuity surfaces arise between the warm foehn current, which is obliged to slide over a colder mass, and the Pc air to the east. Cyclones are easily produced from this phenomenon and take the form of unstable waves which propagate along the discontinuity surface between the two dissimilar masses. A continual series of such cyclones was found to occur as long as the Great Basin anticyclone is maintained with undiminished intensity.

III. Weather conditions associated with the Akron disaster.
This situation illustrates the speedy development and propagation of young disturbances in the eastern United States during the spring of the year under the influence of the conditionally unstable tropical maritime air masses which characterise the region. It also furnishes an excellent example of the superiority of air mass and frontal methods of weather prediction for aircraft operation over the older methods based upon pressure distribution.

IV. The Los Angeles storm of December 30, 1933 to January 1, 1934.
This discussion points out some of the fundamental interactions occurring between air masses of the North Pacific Ocean in connection with Pacific Coast storms and the value of topographic and aerological considerations in predicting them. Estimates of rainfall intensity and duration from analyses of this type may be made and would prove very valuable in the Los Angeles area in connection with flood control problems.

Estudo aberto prospectivo de 30 pacientes com onicomicose por Scytalidium spp. tratados com terbinafina oral, ciclopiroxolamina esmalte e onicoabrasão

Onicomicose é um termo geral usado para definir infecção fúngica da unha. Seus agentes podem ser dermatófitos, leveduras ou fungos filamentosos não dermatófitos - FFNDs. Estes são comumente encontrados na natureza como saprófitas do solo e de restos vegetais e patógenos de plantas e têm sido considerados fungos patógenos primários de lesões cutâneas. Não existe até o momento terapêutica padrão para o tratamento de onicomicoses por Scytalidium spp., sendo escassos os dados na literatura pesquisada. Este trabalho tem como objetivo avaliar e comparar a resposta terapêutica a três abordagens diferentes de tratamento combinado para onicomicose por Scytalidium spp., todos associados à onicoabrasão. Foram selecionados 30 pacientes com diagnóstico de onicomicose provocada por Scytalidium spp., divididos em três grupos de dez, recebendo cada um os seguintes tratamentos, além da onicoabrasão: Grupo I: Terbinafina oral e esmalte de ciclopiroxolamina 8%, duas vezes por semana por 12 meses; Grupos II e III: Esmalte de ciclopiroxolamina 8%, duas e 5 vezes por semana, respectivamente, por 12 meses. Os parâmetros de avaliação da eficácia foram clínico e micológico ao término do tratamento e seis meses após. Foram utilizados os critérios de cura total, cura parcial, falha terapêutica aos 12 meses e recidiva/reinfecção no acompanhamento de seis meses. Vinte e cinto pacientes completaram o estudo. Não houve diferença estatística entre os grupos nos diversos parâmetros utilizados para avaliação da resposta terapêutica. A avaliação do resultado terapêutico mostra que ao final de 12 meses de tratamento apenas um paciente preencheu os critérios para cura total, e que 32% dos pacientes de todos os grupos apresentaram cura parcial. Todos os pacientes que completaram o estudo obtiveram melhora clínica, que se manteve no período de acompanhamento. A presença dos fungos na lâmina ungueal foi constante, mesmo com a melhora clínica. Embora não se possa afirmar qual a melhor forma de intervenção entre as três terapêuticas propostas devido ao pequeno número de pacientes do estudo, deduz-se, deste trabalho, que não houve vantagem na administração de terapia sistêmica concomitante. É possível considerar que a terapia tópica exclusiva, seja duas ou cinco vezes por semana, possa constituir opção mais adequada para o tratamento da onicomicose por Scytalidium spp.

On the diel rhythm of motor activity in perch [Translation from: Informatsionnyi Byulleten Biologiya Vnutrennikh Vod No.30, 12-14, 1976]

The river perch (Perca fluviatilis L.) is most active in the daytime hours, and displays seasonal changes of diel rhythm with a break of the rhythm in spring and autumn. In the present work data were obtained on the motor activity of 3 perch measuring l8-20 cm, caught by net in the littoral of a reservoir and spawned under laboratory conditions. The degree of intensity of movement of perch was judged by special experiments. The results are summarised in this short paper.

Epidermis differentiation in Salmo irideus Gilb. development [Translation from: Archo ital.Anat.Embriol. 76, 19-30, 1971]

Recent histochemical and histophysiological research on the skin of fish has posed interesting problems both with regard to the presence of specialized types of cell and with regard to the function of this organ. The present paper intends to study the development and the functional differentiation of the trout's skin, both from the histomorphological and the histochemical point of view. The skin of Salmonids is devoid of specialized cells; the granular cells of Petromyzonti, the serous cells of Selacii and the clavate cells described in many other teleosts and it lacks keratin. As such it can be considered a good working model which can be used to show the eventual histomorphological and histochemical changes occurring both in the transformation from the endovular to the aqueous environment. Histomorphological observations were carried out demonstrate the great structural simplicity of the trout's skin at all stages. The article concludes that glycogen increases greatly when the epidermis thickens and therefore when it becomes necessary to guarantee resistance, amongst which is a support mechanism.

Comparative drift studies on streams in lower Austria (Flysch, gneiss and chalk formations) [Translation from: Schweizerische Zeitschrift fur Hydrobiologie 30 138-185, 1968.]

Seasonal changes and flooding have an extraordinarily great influence on the drift of organisms. The free water space plays the main part in the provision of food for some fish (Salmo trutta - trout): drift and content of the stomach are balanced here (Simuliidae): whereas others (Thymallus vulgaris) only selectively chose certain animals living at the bottom (molluscs). The total drift, drift of organisms and drift of organic material and minerals, plays a main role in the rate of production in streams. Besides the biology of the organisms living on the river bed, also the geological and hydrographical situation of the area plays a very important role for the composition of the drift. During the years 1964-1966 three streams in the characteristical geological formations flysch, gneiss and chalk of lower Austria were studied in regard to their drift. The Tulln (above St. Christopen), the Krems (above Senftenberg) and the Schwarza (above Hirschwang) seemed to be ideal for this comparative study because they are easy to reach. After summarising the hydrography and chemistry of examined rivers, the author examines the relationship between water level and total drift and the stratification of the total drift before analysing the drift of living organisms. Also considered are seasonal changes of drift of organisms and drift of exuviae.

Profile soundings in lakes of the younger morainal area of Sleswick-Holstein with a sediment-echo-sounder of 30 kHz [Translation from: Wass.Boden 26, 135-138, 1974]

To be able to carry out physical, chemical and biological investigations on a lake, one needs a thorough knowledge of the volume of water and the shape of the lake basin. Little is known about the about the morphology of the lakes in Schleswig-Holstein and its ecological consequences. For this research a 30 KHz echo sounder with sediment transceiver was used to carry out profile determinations (echo soundings). This apparatus continuously records on paper the different reflexions and absorptions of the sediment and water body in the corresponding depth. By this, acoustically noticeable layers and different densities in the sediment and 'scattering layers' in the water body due to physical, chemical and biological reasons (e.g. plans and single fish) are made visible. Result are summarised here regarding the echo soundings in Blunker See.

Femtosecond optical Kerr effect study of Ge(10)AS(40)S(30)Se(20) film

The results of the femtosecond optical heterodyne detection of optical Kerr effect at 805 nm with the 80 fs ultrafast pulses in amorphous Ge10As40S30Se20 film is reported in this paper. The film shows an optical non-linear response of: 200 fs under ultrafast 80 fs-pulse excitation and the values of real and imaginary parts of non-linear susceptibility chi((3)) were 9.0 X 10(-12) and -4.0 X 10(-12) esu, respectively. The large third-order non-linearity and ultrafast response are attributed to the ultrafast distortion of the electron orbits surrounding the average positions of the nucleus of Ge, As, S and Se atoms. This Ge10As40S30Se20 chalcogenide glass would be expected as a promising material for optical switching technique. (c) 2005 Elsevier Ltd. All rights reserved.

Devido às marmeladas, adeus carnaval. Um dia voltaremos: escolas de samba e cultura popular no Rio de Janeiro dos anos 30

Esta dissertação versa sobre o carnaval das escolas de samba, em seu período de formação, na década de 1930. Apresentando a Vizinha Faladeira procura-se identificar suas transgressões no contexto da institucionalização do chamado tradicional carnaval das escolas de samba da cidade. Busca-se compreender os motivos que levaram a Vizinha Faladeira a afastar-se das disputas carnavalescas e terminar suas atividades como escola de samba identificando assim as diversas tensões que circundavam o carnaval das escolas de samba. Verificando os desfiles da Vizinha Faladeira identificam-se formas estéticas diversas que revelam os diálogos tensionados entre os diversos grupos da sociedade e o desejo de fazer um carnaval cada vez mais popular. Este trabalho busca lançar um novo olhar sobre a festa carnavalesca entendendo a cultura popular como o local de disputas de significados simbólicos, rompendo-se com as visões folclóricas e antropológicas, privilegiando as disputas entre os grupos e as representações nas formas artísticas das escolas de samba
