    Science and Christianity: The Positive Attitude

    The Judeo-Christian Scriptures have been considered by literalists as true in every aspect, including references to the sciences. Scripture states that earth has four corners suggesting that the earth is flat. The sun rises in the morning suggesting that the sun goes around the earth, and earth with humankind is at the centre of the universe. The six days in the Genesis account along with the genealogical chronologies were used by Irish Bishop James Ussher (1581-1652) to calculate that the earth\u27s origin was in 4004 B.C. The Genesis account relates that the origin of humankind, and all the plants and animals, is by creation, a coming into existence out of nothing instantaneously

    Variable Factors in the Determination of Fat and Moisture in Cheddar Cheese

    The rapid growth of the dairy industry which began in the latter half of the nineteenth century necessitated the development of chemical tests for determining the composition of dairy products. Chemists devoted much study and labor in devising methods which would be both accurate and rapid. As a result of these researches a large number of tests were developed. Many of the methods possessed considerable merit and a few were so satisfactory that the rest did not come into general use. The basic principles of all the tests now in use were discovered between 1880 and 1890

    Crustal seismic velocity responds to a magmatic intrusion and seasonal loading in Iceland's Northern Volcanic Zone.

    Seismic noise interferometry is an exciting technique for studying volcanoes, providing a continuous measurement of seismic velocity changes (dv/v), which are sensitive to magmatic processes that affect the surrounding crust. However, understanding the exact mechanisms causing changes in dv/v is often difficult. We present dv/v measurements over 10 years in central Iceland, measured using single-station cross-component correlation functions from 51 instruments across a range of frequency bands. We observe a linear correlation between changes in dv/v and volumetric strain at stations in regions of both compression and dilatation associated with the 2014 Bárðarbunga-Holuhraun dike intrusion. Furthermore, a clear seasonal cycle in dv/v is modeled as resulting from elastic and poroelastic responses to changing snow thickness, atmospheric pressure, and groundwater level. This study comprehensively explains variations in dv/v arising from diverse crustal stresses and highlights the importance of deformation modeling when interpreting dv/v, with implications for volcano and environmental monitoring worldwide

    Variation in fatty acid content among benthic invertebrates in a seasonally driven system

    At temperate latitudes where seasonal changing environmental conditions strongly affect the magnitude, duration and species composition of pelagic primary production, macrobenthic organisms living below the photic zone rely on the sedimentation of organic matter as their primary energy source. The succession from nutritious spring blooms to summer cyanobacteria is assumed to reduce food quality for benthic primary consumers and their fatty acid (FA) profiles. In contrast, we find low seasonal variability in FA content of five benthic macroinvertebrates spanning two trophic levels in the Baltic Sea, a system with high seasonal variation in phytoplankton species composition. However, levels of the major FA groups vary greatly between benthic species. The results suggest that benthic macroinvertebrates have evolved FA metabolism adapted to degraded sedimenting material. Moreover, our study shows that species composition of benthic macrofauna rather than seasonal changing conditions affect availability of essential nutrients to higher trophic levels

    HPV infection, anal intra-epithelial neoplasia (AIN) and anal cancer: current issues.

    BACKGROUND: Human papillomavirus (HPV) is well known as the major etiological agent for ano-genital cancer. In contrast to cervical cancer, anal cancer is uncommon, but is increasing steadily in the community over the last few decades. However, it has undergone an exponential rise in the men who have sex with men (MSM) and HIV + groups. HIV + MSM in particular, have anal cancer incidences about three times that of the highest worldwide reported cervical cancer incidences. DISCUSSION: There has therefore traditionally been a lack of data from studies focused on heterosexual men and non-HIV + women. There is also less evidence reporting on the putative precursor lesion to anal cancer (AIN - anal intraepithelial neoplasia), when compared to cervical cancer and CIN (cervical intraepithelial neoplasia). This review summarises the available biological and epidemiological evidence for HPV in the anal site and the pathogenesis of AIN and anal cancer amongst traditionally non-high risk groups. SUMMARY: There is strong evidence to conclude that high-grade AIN is a precursor to anal cancer, and some data on the progression of AIN to invasive cancer.RIGHTS : This article is licensed under the BioMed Central licence at http://www.biomedcentral.com/about/license which is similar to the 'Creative Commons Attribution Licence'.
