Abstract The present article investigates the visual elements of the illustrated youth quarterly L’Illustration Juive, which was published in Alexandria between 1929 and 1931 in French and Hebrew. The analysis sets out to expose the ideologies and worldviews informing the publication’s editorial board, as well as the conscious or unconscious message that the quarterly tried to communicate to its young readership. The article explores more than 300 photographs and reproductions that featured in twelve issues published over the journal’s three years of existence. Analysis of the visual elements in this article shows that the quarterly featured many photographs of holy sites in the Land of Israel, as well as reproductions of artworks that reflected the religious Jewish way of life in the diaspora and Israel, including the Jewish calendar and Jewish life cycle. These works hold the Old Testament as a key book for Judaism, as well as for Jewish nationalism. Clearly evident in the visual elements, as in the overall visual messages of the quarterly, is the harmony struck between Jewish nationality, Zionism, and a religious Jewish cultural—or diasporic—world. It was this harmonious view that editor Rabbi David Prato sought to convey, upholding as he did a religious nationalist Jewish future, which he defined in the newspaper as a double tendance.

INTRODUCTION: Schistosomiasis has been described as “one of the most devastating diseases of mankind, second only to malaria in its deleterious effects on the social and economic development of populations in many warm areas of the world.” The disease is worldwide and is probably spreading faster and becoming more intense than the overall research efforts designed to provide the basis for countering it. Moreover, there are indications that the development of water resources and the demands for increasing cultivation and food in developing countries may prevent adequate control of the disease and thus the number of infections are increasing.Our knowledge of the basic biology of the parasites causing the disease is far from adequate. Such knowledge is essential if we are to develop a rational approach to the effective control of human schistosomiasis. The miracidium is the first infective stage in the complex life cycle of schistosomes. The future of the entire life cycle depends on the capacity and ability of this organism to locate and enter a suitable snail host for further development, Little is known about the nervous system of the miracidium of Schistosoma mansoni and of other trematodes. Studies indicate that miracidia contain a well developed and complex nervous system that may aid the larvae in locating and entering a susceptible snail host (Wilson, 1970; Brooker, 1972; Chernin, 1974; Pan, 1980; Mehlhorn, 1988; and Jones, 1987-1988).

The plasma membrane of the Slime Mold, Physarum polycephalum, process unique morphological distinctions at different stages of the life cycle. Investigations of the plasma membrane of P. polycephalum, particularly, the arrangements of the intramembranous particles has provided useful information concerning possible changes occurring in higher organisms. In this report Freeze-fracture-etched techniques were used to investigate 3 hours post-fusion of the macroplasmodia stage of the P. polycephalum plasma membrane.Microplasmodia of Physarum polycephalum (M3C), axenically maintained, were collected in mid-expotential growth phase by centrifugation. Aliquots of microplasmodia were spread in 3 cm circles with a wide mouth pipette onto sterile filter paper which was supported on a wire screen contained in a petri dish. The cells were starved for 2 hrs at 24°C. After starvation, the cells were feed semidefined medium supplemented with hemin and incubated at 24°C. Three hours after incubation, samples were collected randomly from the petri plates, placed in plancettes and frozen with a propane-nitrogen jet freezer.
