Effective Treatments for Dry Eye Disease Presentation

«La metodología de investigación se comprende cabalmente en el proceso mismo del trabajo científico donde las consideraciones teóricas sobre el método se enfrentan a una situación concreta: la investigación científica en determinada área del conocimiento. De acuerdo con esto, puede decirse que ningún texto sobre metodología enseña a investigar, sino solamente puede indicar, en términos generales, el camino que hay que recorrer, y la forma de hacerlo, para tratar de obtener resultados fecundos para la ciencia. Sin duda, serán las características propias del objeto de estudio y el nivel de análisis que requiera alcanzarse, vinculado esto último con los objetivos de la investigación, los que modelarán la aplicación del método científico. De lo anterior se desprende que la metodología de investigación no es un conjunto de preceptos y procedimientos elaborados en forma definitiva susceptibles de aplicarse indistintamente a cualquier problema de investigación. El método científico se afina, se ajusta a los requerimientos concretos de la investigación y en su aplicación adecuada juega un papel de singular importancia la imaginación creativa, la cual ha sido un factor fundamental en el desarrollo del conocimiento y del mismo método científico».

The object of this study is to analyze 10 years of 11-S with four conflicts that remain open in the Middle East region. In methodological terms, the study of conflict scenarios allows us a cognitive map of the state of situation and its development during the period chosen, identifying ideas, dynamics, actors, interactions, and the effects on each of them and between them, despite the fact that its approach is performed separately. With the exception of the Arab-Israeli conflict, considered the mother of all battles, after 11-S We identified the emergence of another 3 in the turbulent Middle East region: the global struggle against international terrorism and interventions in Afghanistan and Iraq; the discovery of the nuclear development of Iran with the perception of regional and international threat and the Arab Awakening that from 2011 generated a process of alteration of the status quo with consequences difficult to measure.

There are many people who I would like to thank, but the word count doesn't leave enough margins for me to do so.

The essay examines the frequently expressed claim that the lied has unmediated access to the most interior regions of individual listeners; that claim functions ideologically to reinforce a belief in the viability of the free individual in bourgeois society. This ideology is explored through an examination of Schubert's "Alinde" (D. 904) and a brief consideration of the two songs published with it, "An die Laute" (D. 905) and "Zur guten Nacht" (D. 903), in the context of the values of the German-speaking educated classes that formed the lied's principal audience in the nineteenth century. By considering music both as an autonomous aesthetic object (as the ideology proposes) and as a marker of collective identity and self-definition, this approach reveals social implications of features of "Alinde" that have previously been considered only in a stylistic context. Among these are the barcarolle as a reference to idyllic peasant society (...

Identity is a post-colonial issue that cuts across most colonized territories as the citizens try to either mold themselves and their offsprings into the image of the colonials. Many at times it is the idea that the acceptable negro is a black man with white man’s mannerisms and characteristics that drive these colonized territories into conforming to the ways of the colonials by modeling themselves after the colonials. Chika Unigwe’s On black Sisters’ Street outlines some of the challenges of colonized countries such as Nigeria and Sudan where her major characters born. This paper re-examines the identity issue in text as a post-colonial effect. It takes to account the harsh realities faced by the women out of their home country into uncertainty and eventually death. The paper utilizes the post-colonial theory and Homi Bhabha’s Hybridity to account for the occurrences in the text which embodies post-colonial tendencies and experiences such as migration, identity, disillusionment and home and belonging. The paper concludes that there exists a perpetual longing for home, which is the common geographical connection of the women as Africans, regardless of the strange identities assumed by these women towards their voyage for survival.

Climbing-ripple cross-lamination is most commonly deposited by turbidity currents when suspended load fallout and bedload transport occur contemporaneously. The angle of ripple climb reflects the ratio of suspended load fallout and bedload sedimentation rates, allowing for the calculation of the flow properties and durations of turbidity currents. Three areas exhibiting thick (>50 m) sections of deep-water climbing-ripple cross-lamination deposits are the focus of this study: (i) the Miocene upper Mount Messenger Formation in the Taranaki Basin, New Zealand; (ii) the Permian Skoorsteenberg Formation in the Tanqua depocentre of the Karoo Basin, South Africa; and (iii) the lower Pleistocene Magnolia Field in the Titan Basin, Gulf of Mexico. Facies distributions and local contextual information indicate that climbing-ripple cross-lamination in each area was deposited in an ‘off-axis’ setting where flows were expanding due to loss of confinement or a decrease in slope gradient. The resultant reduction in flow thickness, Reynolds number, shear stress and capacity promoted suspension fallout and thus climbing-ripple cross-lamination formation. Climbing-ripple cross-lamination in the New Zealand study area was deposited both outside of and within channels at an inferred break in slope, where flows were decelerating and expanding. In the South Africa study area, climbing-ripple cross-lamination was deposited due to a loss of flow confinement. In the Magnolia study area, an abrupt decrease in gradient near a basin sill caused flow deceleration and climbing-ripple cross-lamination deposition in off-axis settings. Sedimentation rate and accumulation time were calculated for 44 climbing-ripple cross-lamination sedimentation units from the three areas using TDURE, a mathematical model developed by Baas et al. (2000). For Tc divisions and Tbc beds averaging 26 cm and 37 cm thick, respectively, average climbing-ripple cross-lamination and whole bed sedimentation rates were 0·15 mm sec−1 and 0·26 mm sec−1 and average accumulation times were 27 min and 35 min, respectively. In some instances, distinct stratigraphic trends of sedimentation rate give insight into the evolution of the depositional environment. Climbing-ripple cross-lamination in the three study areas is developed in very fine-grained to fine-grained sand, suggesting a grain size dependence on turbidite climbing-ripple cross-lamination formation. Indeed, the calculated sedimentation rates correlate well with the rate of sedimentation due to hindered settling of very fine-grained and fine-grained sand–water suspensions at concentrations of up to 20% and 2·5%, respectively. For coarser grains, hindered settling rates at all concentrations are much too high to form climbing-ripple cross-lamination, resulting in the formation of massive/structureless S3 or Ta divisions.
