Historical Moment

Holography has been used as a way of artistic expression, but it has little presence in art events, neither in articles about holographic woks in specialized magazines are very common, although valuable creators have experienced it, since the catalán Salvador Dalí to the american Bruce Nauman.This text explorer the cause of this poor presence. It’s strange that something so attractive and visually rich (also simbolically) is not visible in our historical moment, characterized by the voracity of convert in artistic resource any possible element.After research about the development of holographyc on the field of art, I formed a hypothesis about the reasons of their limited presence: The lack of synergy between scientific institutions and those dedicated to art, the disinterest of the commissioners and the lack of information. It is not enough whit the objects that are produced by isolated artists in their studios, art is a system of relationships where the work is involved as an other element of a structure.

The late period of Ivan Franko's artistic work is characterized by the presence of a number of stories that contain a naturalistic reproduction of Jewish themes. In such stories as «Pure Race», «In the Prison Hospital», «In the Carpentry», «In the Forge (From My Memories)» there are memories of the author about different stages of his life, which clearly distinguishes the Jewish theme revealed by naturalistic means.The story «Pure Race» demonstrates the collision in the life of an old Jew who found himself in a compartment of a train with representatives of other nationalities. The description of events in the compartment is presented with elements of naturalism – the use of factualism and a detailed description of events, the objectivity of the image. The story «In the prison hospital» has the following naturalistic features: the story tells about the stay in the hospital of two or three seriously ill people with a detailed description of the circumstances of their lives with factual accuracy. The story «In the Carpentry» contains a fragment from the life of a Jew, written by the author from his youthful memories and under the influence of a certain historical moment. The story describes the terrible murder of calves by a Jewish boy, with the fixation of all the details that convey all the burden of what was seen in the soul of the hero. The story «In the Forge (From my memories)» contains the author's childhood memories from his stay in the father's forge with the recording of all the small moments of his impressions. In the memoirs there is a naturalistic description with a detailed account of events in life of Boryslav.In the above stories, with the help of naturalistic means, the problems of Jewish life in Galicia are reproduced. Among the naturalistic features of the depiction of Jewish figures there are: factography, detailed description with fixation of all the details as a consequence of scientific accuracy, plausibility, objectivity of reproduction and unity in the depiction of natural and social factors, which together makes the reader their witness.

AbstractThis paper examines the actions of one Salvadorean priest – Padre David Rodríguez – in one parish – Tecoluca – to underscore the importance of religious leadership in the rise of El Salvador's contentious political movement that began in the early 1970s, when the guerrilla organisations were only just beginning to develop. Catholic leaders became engaged in promoting contentious politics, however, only after the Church had experienced an ideological conversion, commonly referred to as liberation theology. A focus on one priest, in one parish, allows for generalisation, since scores of priests, nuns and lay workers in El Salvador followed the same injustice frame and tactics that generated extensive political mobilisation throughout the country. While structural conditions, collective action and resource mobilisation are undoubtedly necessary, the case of religious leaders in El Salvador suggests that ideas and leadership are of vital importance for the rise of contentious politics at a particular historical moment.

Spatial Frequencies

The problem of "understandinq" electron microscope imaqes becomes more acute as the resolution is improved. The naive interpretation of an imaqe as representinq the projection of an atom density becomes less and less appropriate. We are increasinqly forced to face the complexities of coherent imaqinq of what are essentially phase objects. Most electron microscopists are now aware that, for very thin weakly scatterinq objects such as thin unstained bioloqical specimens, hiqh resolution imaqes are best obtained near the optimum defocus, as prescribed by Scherzer, where the phase contrast imaqe qives a qood representation of the projected potential, apart from a lack of information on the lower spatial frequencies. But phase contrast imaqinq is never simple except in idealized limitinq cases.

Lack Of Information

An understanding of the specific interactions of actin with regulatory proteins has been limited by the lack of information about the structure of the actin filament. Molecular actin has been studied in actin-DNase I complexes by single crystal X-ray analysis, to a resolution of about 0.6nm, and in the electron microscope where two dimensional actin sheets have been reconstructed to a maximum resolution of 1.5nm. While these studies have shown something of the structure of individual actin molecules, essential information about the orientation of actin in the filament is still unavailable.The work of Egelman & DeRosier has, however, suggested a method which could be used to provide an initial quantitative estimate of the orientation of actin within the filament. This method involves the quantitative comparison of computed diffraction data from single actin filaments with diffraction data derived from synthetic filaments constructed using the molecular model of actin as a building block. Their preliminary work was conducted using a model consisting of two juxtaposed spheres of equal size.

Amphibians have paired muscular pump organs, called “lymph heart”, which rhythmically pump back the lymph from the large subcutaneous lymph sacs into the veins. The structure and ultrastructure of these organs is well known but to date there is a lack of information about the innervation of lymph hearts. Therefore has been carried out an ultrastructural study in order to study the distribution of the nerve fibers, and the morphology of the neuromuscular junctions in the lymph heart wall.

Abstract. Background: Early identification and appropriate referral services are priorities to prevent suicide. Aims: The aim of this study was to describe patterns of identification and referrals among three behavioral health centers and determine whether youth demographic factors and type of training received by providers were associated with identification and referral patterns. Method: The Early Identification Referral Forms were used to gather the data of interest among 820 youth aged 10–24 years who were screened for suicide risk (females = 53.8%). Descriptive statistics and binary logistic regressions were conducted to examine significant associations. Results: Significant associations between gender, race, and age and screening positive for suicide were found. Age and race were significantly associated with different patterns of referrals and/or services received by youths. For providers, being trained in Counseling on Access to Lethal Means was positively associated with number of referrals to inpatient services. Limitations: The correlational nature of the study and lack of information about suicide risk and comorbidity of psychiatric symptoms limit the implications of the findings. Conclusion: The results highlight the importance of considering demographic factors when identifying and referring youth at risk to ensure standard yet culturally appropriate procedures to prevent suicide.

Purpose. In this article, the authors propose useful operational indications to approach in the best possible way the issues concerning the design of a facility for manufacturing radiopharmaceuticals, with focus on organizational and safety aspects. Methods. Several documents produced by authoritative bodies, national and international scientific institutions and associations were examined and referenced, to the purpose of reviewing all available information in the field. Results. Indications are gathered for the design stage, including the organization of accesses and routes and characteristics and requirements of premises and systems. Conclusions. Main goal is to guide the reader in evaluating and choosing the most suitable features and equipment to limit the risks due to ionizing radiation and to prevent contamination of the workers and the environment.
