Abstract: We have measured parity violating asymmetries in elastic electron-proton and quasi-elastic electrondeuteron scattering at backward electron angle. These measurements have been done at two momentum transfers : Q2 = 0.22 and 0.63 (GeV/c)2 . Together with our previous forward angle measurement [1], we can extract strange quark contributions to the electromagnetic form factors of the nucleon, as well as nucleon axial form factor coming from the neutral weak interaction. The results indicate a strange quark magnetic contribution close to zero at these Q2 , and a possible non zero strange quark electric contribution for the high Q2 . The rst Q2 behavior measurement of the nucleon axial form factor in elastic electron scattering shows a good agreement with radiative corrections calculated at Q2 = 0 and with a dipole form using the axial mass determined in neutrino scattering.
Porosity and Lithology Prediction in Eve Field, Niger Delta Using Compaction Curves and Rock Physics Models  [PDF]

International Journal of Geosciences (IJG) , 2011, DOI: 10.4236/ijg.2011.23039
Abstract: The primary objective of this study is to investigate the porosity-depth trends of shales and sands and how they affect lithologies. Compaction curves from well logs of five wells were determined using interval transit time from sonic logs. The depth of investigation lies between 1087 m and 2500 m. Based on the shale and sand trend modeling, the study intends to determine the model to be used for lithology prediction at various depths given the interplay between shale and sand compaction. The improved understanding of the physical properties of shales and sands as a function of burial depth was demonstrated, in conjunction with a good understanding of how compaction affects lithology. The compaction curve for shale and sand lithologies varies with shale being parabolic in form, and sands with linear and exponential in nature. Plots of sonic porosity against depth show great dispersion in porosity values while plotting porosity values against depth for different lithologies produced well-defined porosity trends. This shows decrease in porosity with depth. The negative porosity trend is less marked in sandstones, and faster in shale which suggests that it is possible to make accurate porosity predictions using compaction trend. The porosity trend showed exponential relationship at small depth less than 2500m. The linear and exponential models are not dependable at large depth. The result shows that the compaction models applicable for sandstones do not necessary apply for shales.

Abstract: A redox active medicinal plant and L-leucine mixture (HLM) was investigated in subjects with established osteoarthritis of the knee in a multi-center, rando- m-ized, placebo-controlled, double-blind clinical trial. A total of 96 subjects with osteoarthritis were enrolled and randomized to either placebo (n = 38) or HLM treatment group (n = 38). The HLM group re- ceived a combination of Uncaria tomentosa (300 mg), Boswellia serrata (200 mg), Lepidium meyenii (1000 mg) and L-Leucine (700 mg) given as 3 capsules once a day. The placebo group received matching capsules with carboxymethylcellulose. The treatment period was 8 weeks, with assessments made at days 7, 14, 28 and 56. The primary outcome was reduction in total WOMAC score. VAS pain, tolerability, investigator assessments, use of rescue medication (acetominophen), and safety assessments of vital signs and laboratory assessments were included. Subject randomization was effective for age, gender and disease severity. In the placebo group 32/38 subjects completed the trial and for HLM 35/38. WOMAC scores (pain, stiffness, physical performance and total) steadily declined over the course of the 8 week study in both groups, but the magnitude was significantly greater for HLM (P < 0.05). Total WOMAC was reduced 46.5% for HLM and 25.4 % for placebo. VAS pain was reduced 21.8% in the placebo group (p < 0.002) but the changes were significantly greater (37.8% p < 0.03) with HLM treatment. Investigator’s global assessment rating of good-excellent was 24/35 (69%) for HLM and 14/32 (44%) for placebo (P = 0.05). Rescue medication consumption and tolerability were comparable for HLM and placebo. No safety issues were evident with either group. As expected a placebo effect was observed, nevertheless HLM was clearly more effective in relieving the symptoms of osteoarthritis. This HLM represents a safe and effective new approach to the management of osteoarthritis symptoms.
Simian virus 40, poliovirus vaccines, and human cancer: research progress versus media and public interests
Bulletin of the World Health Organization , 2000,
Abstract: from 1955 through early 1963, millions of people were inadvertently exposed to simian virus 40 (sv40) as a contaminant of poliovirus vaccines; the virus had been present in the monkey kidney cultures used to prepare the vaccines and had escaped detection. sv40 was discovered in 1960 and subsequently eliminated from poliovirus vaccines. this article reviews current knowledge about sv40 and considers public responses to reports in the media. sv40 is a potent tumour virus with broad tissue tropism that induces tumours in rodents and transforms cultured cells from many species. it is also an important laboratory model for basic studies of molecular processes in eukaryotic cells and mechanisms of neoplastic transformation. sv40 neutralizing antibodies have been detected in individuals not exposed to contaminated poliovirus vaccines. there have been many reports of detection of sv40 dna in human tumours, especially mesotheliomas, brain tumours and osteosarcomas; and dna sequence analyses have ruled out the possibility that the viral dna in tumours was due to laboratory contamination or that the virus had been misidentified. however, additional studies are necessary to prove that sv40 is the cause of certain human cancers. a recently published review article evaluated the status of the field and received much media attention. the public response emphasized that there is great interest in the possibility of health risks today from vaccinations received in the past.
La tuberculosis y sus epónimos: Charles Mantoux (1877-1947)
Revista Espa?ola de Sanidad Penitenciaria , 2009, DOI: 10.4321/S1575-06202009000100004
Abstract: in 1908, charles mantoux, a french doctor perfected a test for the diagnosis of tuberculosis contact (latent tuberculosis). this study reviews the history of this technique, which is closely linked to the symbolism and mythology of an illness that at one time was known as the white plague.
Paul and sophistic rhetoric: a perspective on his argumentation in the letter to the Galatians
J.S Vos
Acta Theologica , 2008,
Abstract: In this article Paul’s argumentation is analysed from the perspective of sophistic rhetoric. In the first section the question is discussed what it means to label Paul’s rhetoric in his Letter to the Galatians ‘sophistic.’ To that end, an attempt is made to reconstruct the view of a contemporary critical reader who did not share Paul’s presuppositions and who was well acquainted with the discussions in the philosophical and rhetorical schools about acceptable and non-acceptable rhetorical methods. This approach is compared with other approaches to analysing Paul’s argumentation. The second section investigates more closely what it means when ‘sophistic rhetoric’ is used as a key to analyse Paul’s theology. To that end, some models which start from a ‘Platonic’ view of rhetoric are compared with a model which combines a ‘(neo-) sophistic’ or constructionist view with a ‘rhetoric of power.’

Abstract: In his long address called “Why Lausanne?” Dr Billy Graham clearly stated the reason and purpose to have the International Congress on World Evangelization by saying that “we are met to pray, talk, plan and to advance the work of evangelism ,” and he adds: “This is a conference of evangelicals. The participants were asked to come because you are evangelical-concerned with evangelism and missions; and we here tonight stand firmly in the evangelical tradition of Biblical faith.” Here we can find two specific reasons for the congress: to discuss for furtherance of world evangelism and to bring evangelicals together for a united front of the world evangelization. For this purpose the invitations were sent to all over the world. According to statistics published officially by the congress six continents sent their representatives to the congress responding to the invitation though it was sent on individual basis: 458 from Africa, 729 from Asia, 1 115 from North and Central America, 777 from Europe, 180 from South America and 150 from Oceania. Literally it was a world-wide congress. There was never such a large gathering before on a single purpose.
