Background: Exposure to solar ultraviolet-B (UV-B) radiation is a major source of vitamin D3. Chemistry climate models project decreases in ground-level solar erythemal UV over the current century. It is unclear what impact this will have on vitamin D status at the population level. The purpose of this study was to measure the association between ground-level solar UV-B and serum concentrations of 25-hydroxyvitamin D (25(OH)D) using a secondary analysis of the 2007 to 2009 Canadian Health Measures Survey (CHMS). Methods: Blood samples collected from individuals aged 12 to 79 years sampled across Canada were analyzed for 25(OH)D (n=4,398). Solar UV-B irradiance was calculated for the 15 CHMS collection sites using the Tropospheric Ultraviolet and Visible Radiation Model. Multivariable linear regression was used to evaluate the association between 25(OH)D and solar UV-B adjusted for other predictors and to explore effect modification. Results: Cumulative solar UV-B irradiance averaged over 91 days (91-day UV-B) prior to blood draw correlated significantly with 25(OH)D. Independent of other predictors, a 1 kJ/m 2 increase in 91-day UV-B was associated with a significant 0.5 nmol/L (95% CI 0.3-0.8) increase in mean 25(OH)D (P =0.0001). The relationship was stronger among younger individuals and those spending more time outdoors. Based on current projections of decreases in ground-level solar UV-B, we predict less than a 1 nmol/L decrease in mean 25(OH)D for the population. Conclusions: In Canada, cumulative exposure to ambient solar UV-B has a small but significant association with 25(OH)D concentrations. Public health messages to improve vitamin D status should target safe sun exposure with sunscreen use, and also enhanced dietary and supplemental intake and maintenance of a healthy body weight.

In this paper I have attempted to explore "covenant" in faith and history, as it extends throughout the entire framework of the Bible and the entire history of the people who produced it. With such a monstrous topic, a comprehensive analysis of the material could take a lifetime to do it justice. Therefore, I have taken a very specific approach to the material in order to investigate the evolution of covenant from the Hebrew Bible (Old Testament) to the Christian Scriptures (New Testament). I have made every effort to approach this thesis as a text-based, non-doctrinal discussion. However, having my own religious convictions, it has, at times, been difficult to recognize and escape my biases. Nevertheless, I am confident that this final product is, for the most part, objective and free from dogmatism. Of course, I have brought my own perspective and understanding to the material, which may be different from the reader's, so there may be matters of interpretation on which we differ, but c 'est fa vie in the world of religious dialogue. The structure of this paper is symmetrical: Part I examines the traditions of the Torah and the Prophets; Part II, the Gospels and Paul's letters. I have balanced the Old Testament against the New Testament (the Torah against the Gospels; the Prophets against Paul) in order to give approximately equal weight to the two traditions, and establish a sense of parallelism in the structure of my overall work. A word should also be said about three matters of style. First, instead of the customary Christian designation of time as B.C. or A.D., I have opted to use the more modem B.C.E. (Before the Common Era) and C.E. (Common Era) notations. This more recent system is less traditional; however, more acceptable in academic and, certainly, more appropriate for a non-doctrinal discussion. Second, in the body of this paper I have chosen to highlight several texts using a variety of colors. This highlighting serves (1) to call the reader's attention to specific passages, and (2) to compare the language and imagery of similar texts. All highlighting has been added to the texts at my own discretion. Finally, the divine name, traditionally vocalized as "Yahweh," is a verbal form of the Hebrew "to be," and means, approximately, "I am who I am." This name was considered too holy to pronounce by the ancient Israelites, and, the word adonai ("My LORD") was used in its stead. In respect of this tradition, I have left the divine name in its original Hebrew form. Accordingly, should be read as "the LORD" throughout this paper. All Hebrew and Greek translations, where they occur, are my own. The Greek translations are based on the New Revised Standard Version (NRSV) of the Bible.

The DO experiment enjoyed a very successful data-collection run at the Fermilab Tevatron collider between 1992 and 1996. Since then, the detector has been upgraded to take advantage of improvements to the Tevatron and to enhance its physics capabilities. We describe the new elements of the detector, including the silicon microstrip tracker, central fiber tracker, solenoidal magnet, preshower detectors, forward muon detector, and forward proton detector. The uranium/liquid -argon calorimeters and central muon detector, remaining from Run 1, are discussed briefly. We also present the associated electronics, triggering, and data acquisition systems, along with the design and implementation of software specific to DO. (c) 2006 Elsevier B.V. All rights reserved.

We report observation of the electroweak production of single top quarks in pp collisions at s=1.96 TeV based on 2.3 fb(-1) of data collected by the D0 detector at the Fermilab Tevatron Collider. Using events containing an isolated electron or muon and missing transverse energy, together with jets originating from the fragmentation of b quarks, we measure a cross section of sigma(pp -> tb+X,tqb+X)=3.94 +/- 0.88 pb. The probability to measure a cross section at this value or higher in the absence of signal is 2.5x10(-7), corresponding to a 5.0 standard deviation significance for the observation.

Dr. Moloney kept a personal journal, with photographs, for much of his two years with the Atomic Bomb Casualty Commission in Japan. Along with other scientists, he studied the biological and medical effects of ionized radiation on the survivors of the Hiroshima and Nagasaki atomic bombings. In January of 1986, Dr. Moloney donated his journal, correspondence and diary pages to the Harris County Medical Archive, whose collections were later incorporated into the Texas Medical Center Library. Dr. Moloney's journal is in relatively good shape containing a mix of handwritten notes and comments, news-clippings, photos, and ephemera. The journal is an important record of personal impressions, thoughts and details of events during a pivotal time in Japan. This 192-pagee journal gives new insights into the work of the ABCC and into the people who participated in that work. The journal covers the period from April 1952 to February 1954. In these documents, Moloney records his struggles with understanding the Japanese culture, his frustration at not being allowed to treat the survivors he studied, and his concerns, fears, hopes and revelations as he dealt with the bombing survivors and their children. The original papers are open for research at the John P. McGovern Historical Collections and Research Center in the TMC Library in Houston.

Filón de Alejandría (30?a. C.-50? d. C.) es una figura clave para conocer la profunda relación entre Judaísmo y Helenismo en el siglo I d. C. Judío practicante, su profundo dominio de la lengua, la literatura y, de modo especial, la retórica griegas lo convierten en una personalidad extraordinaria de su tiempo, tanto por su exégesis de la Torá (o Pentateuco) como por sus escritos apologéticos, históricos y filosóficos. Su testimonio es de gran valor para todo estudioso de la Antigüedad clásica por los muchos datos que aporta acerca de la filosofía, el pensamiento, la educación y la tradición clásica en el momento histórico que le tocó vivir, precisamente en un centro cultural de excepcional importancia dentro del Imperio romano
