OPERA data and The Equivalence Postulate of Quantum Mechanics

An interpretation of the recent results reported by the OPERA collaboration is that neutrinos propagation in vacuum exceeds the speed of light. It has been further been suggested that this interpretation can be attributed to the variation of the particle speed arising from the Relativistic Quantum Hamilton Jacobi Equation. I show that this is in general not the case. I derive an expression for the quantum correction to the instantaneous relativistic velocity in the framework of the relativistic quantum Hamilton-Jacobi equation, which is derived from the equivalence postulate of quantum mechanics. While the quantum correction does indicate deviations from the classical energy--momentum relation, it does not necessarily lead to superluminal speeds. The quantum correction found herein has a non-trivial dependence on the energy and mass of the particle, as well as on distance travelled. I speculate on other possible observational consequences of the equivalence postulate approach.Comment: 8 pages. Standard LaTex. References adde

Ask, Advise, Assist and Follow: An Evidence Based Project to Address Unhealthy Alcohol Use in a Free Clinic Setting

Preventative care in free clinic settings aims to mitigate health risks for vulnerable populations. Heavy alcohol intake is a major threat to physical and mental health. Wellness care for free clinic patients must include regular screening for alcohol use in accordance with national guidelines. The purpose of this project was to implement and evaluate an evidence- based practice change to improve alcohol screening and intervention in a free clinic setting. The NIH/NIAAA screening, brief intervention, and referral for treatment (SBiRT) process was implemented. A convenience sample of de-identified patient charts was reviewed to assess alcohol screening before (n = 38 charts) and after (n = 30) a staff education intervention; data collected (n = 68) did not include demographic or patient identifiers to protect privacy. Comparison of HEDIS scores before and after intervention showed improved alcohol screening and intervention/referral for treatment rates

History of the 902nd Ordnance Heavy Automotive Maintenance Company, 1942, 1943, 1944, 1945

This is the story, the history, of a group of men; organized out of all walks of life; from the hills and the mountains; the valleys and the plains; from the farms and the cities; from the rich and the poor organized for war. This is a tale that lives deep in in the hearts of these men; their wives, their mothers, sisters and brothers; their children. Written out of toil and sweat; oils and grease; nuts and bolts -- engines, wheels and axles; the things that made modern war possible and hastened its end.https://digicom.bpl.lib.me.us/ww_reg_his/1001/thumbnail.jp

Costs and cost-effectiveness of alternative tuberculosis management strategies in South Africa - Implications for policy

Objective. To conduct an economic analysis of the Hlabisa community-based directly observed therapy management strategy for tuberculosis and to project costs of three alternative strategies. Setting. Hlabisa health district, KwaZulu-Natal, South Africa. Methods. An economic analysis comparing the current tuberculosis management strategy in Hlabisa with three alternative strategies (the Hlabisa strategy prior to 1991 based on hospitalisation, the national strategy and sanatorium care) in terms of costs to both health service and patient and of cost-effectiveness. Results. The current Hlabisa strategy was the most cost-effective (R3 799 per patient cured), compared with R98 307 for the strategy used prior to 1991, R9 940 for the national strategy, and R11 145 for sanatorium care, Between 71% and 88% of treatment costs lie with the health service, and hospitalisation (R119 per day) is the most expensive item. Prolonged hospitalisation is extremely expensive, but community care is cheaper (community clinic visit, R28; community health worker visit, R7). The total cost of supervising a patient in the community under the current Hlabisa strategy was R503, equivalent to 4.2 days in hospital, Drug costs (R157) are equivalent to just 1.3 days in hospital. Conclusion. Cost to both health service and patient can be substantially reduced by using community-based directly observed therapy for tuberculosis, a strategy that is cheap and cost-effective in Hlabisa, These findings have important national implications, supporting the goals of the new tuberculosis control programme.5 page(s
