Issued as a Documentation Report on an Investigation of Field-Made Joints in Prestressed Reinforced Concrete Highway Girder Bridges, Project IHR-303, Phase 2

A prototype bridge girder was designed, built, and tested. The 250 ft long two-span girder was made of 3 precast segments about 88, 74, and 88 ft in length. The segments were supported on 3 final and 2 temporary supports. The joints were of cast-in-place concrete, as was the composite deck. After the site-cast concrete was cured, the structure was post-tensioned to establish continuity and the temporary supports were removed. The two longer segments were pretensioned to resist the girder and deck dead loads, while the shorter segment was reinforced with deformed bars for the same loads. The structure was subjected to a series of loadings, during which deflections, reactions, and concrete strains were measured. The loads approximated AASHTO HS-20 vehicles. The first 4 tests ,were to service loads, with total applied loads of 73.6 kips. The structure remained elastic and crack free during these tests. Two tests were to the design ultimate load, 198.7 kips. A load of 328.2 kips was applied in the final test without causing failure. The final loading was applied to produce maximum shear in one splice, and a shear failure, complicated by large flexural deformations, appeared to be developing when the test ended. The final test produced a maximum deflection of 10.8 in., and a residual of about 1.0 in. The joint details used in the prototype structure were adequate, and the presence of the, joint had no influence on the behavior of the structure until extremely large overloads were reached.State of Illinois Department of TransportationU.S. Department of Transportation.

Mental Health among People Living with HIV (PLWH) in Iran: A Policy Brief Teaser: The necessity of a Tool for Mental Health in PLWH in Iran

Depression and anxiety are the most common mental health disorders in people living with HIV (PLWH). Adherence to antiretroviral therapy (ART) is an important concern that could be significantly affected by psychological problems among PLWH. Therefore, the authors recommend using an anxiety and depression screening tool, among Iranian PLWH in HIV health care system and determine potential barriers to depression screening and effective care

A tailored mHealth intervention for improving treatment adherence for people living with HIV in Iran (HamRaah):Protocol for a feasibility study and randomised pilot trial with a nested realist evaluation

Introduction Middle East and North Africa (MENA) has a rising rate of new HIV infections and AIDS-related mortality. Consistent adherence to antiretroviral therapy (ART) leads to viral suppression, preventing HIV transmission and treatment failure. mHealth interventions can improve ART adherence by providing tailored support and directing patients to existing healthcare services. HamRaah (Persian for ‘together-in-path’) is the first mHealth-based intervention in a MENA country and is designed to improve adherence through two-way mobile messaging for people recently diagnosed with HIV in Tehran, Iran. The objectives of this pilot randomised controlled trial (RCT) are to examine the feasibility, acceptability and preliminary effectiveness of HamRaah, and to develop an explanatory theory for any observed effects through a nested realist evaluation.Methods A feasibility study and two-arm RCT of HamRaah, with an embedded realist evaluation will be conducted. Participants will be randomised 1:1 to HamRaah or routine care for a 6-month intervention. The initial effectiveness of HamRaah will be assessed through the primary outcome of self-reported ART adherence and several secondary outcomes: retention in care, CD4 count and viral suppression. A theory-driven realist evaluation framework will be used to develop an explanatory theory regarding what works, for whom, how and in what context.Ethics and dissemination The study received ethical clearance from Tehran University of Medical Sciences Ethics Committee and Oxford Tropical Research Ethics Committee People living with HIV in Tehran and key country stakeholders in HIV policy and programming have been involved in the development of HamRaah and this pilot trial. Participants will provide informed consent prior to study enrolment. The results will be disseminated to all stakeholders and presented in peer-reviewed journal publications and conferences.Trial registration number IRCT20100601004076N23; Pre-results

Frequency of HIV Infection among Sailors in South of Iran by Rapid HIV Test

Information on the prevalence and risk factors for HIV infection among sailors is scarce. The aim of this seroprevalence study was to evaluate the frequency of HIV infection among sailors in south of Iran using rapid HIV test. The study included 400 consecutive participants in Lengeh, Shahid Rajaie, and Shahid Bahonar ports in south of Iran in May 2010. We observed only one case (0.25%) of HIV infection in this sample of sailors. While prevalence appears low at present, we recommend periodic HIV serosurveillance with detailed behavioral measures for this population in the future

Advanced Colloids Experiment (Temperature Controlled) ACE-T5

The attached will be presented at the JSC Science Symposium as a preview of the ACE-T5 flight experiment. The Principal Investigator (PI) for this experiment is Professor Ali Mohraz at the University of California - Irvine.Bijels (bicontinuous interfacially jammed emulsion gels) were discovered in 2007 at the University of Edinburgh. These materials feature a tubular, bicontinuous arrangement of two fluid phases separated by a monolayer of jammed colloidal particles at the interface.Because of their unique morphological characteristics, bijels hold significant promise as next-generation materials for energy and biotechnology applications. But in order to fully realize their potential, their physics and mechanical properties must be better understood. The mechanical properties and stability of bijels is mediated by an interplay between interfacial forces that impart elasticity to the system, and external stresses. Unfortunately, the interfacial forces are inherently coupled with density differences and cannot be studied systematically in the presence of gravity

An Estimation of HIV/AIDS’s Cost in the Voluntary Counseling and Testing Center of Imam Khomeini Hospital in 2010-2011

Introduction: Undoubtedly, HIV/AIDS is one of the most important emerging infectious disease in the late twentieth century; and its control is possible only with proper and organized program. To attain this goal, one of the most serious issues is the budget planning and distribution. The present study calculated the total costs of AIDS in Voluntary Counseling and Testing center of Imam Khomeini Hospital in 2010-2011.Methods: The total cost of AIDS at this center was divided into four categories: health care, training and educating, research and services. All costs for 2010-2011 were extracted and classified based on documents and bills which were found in the center.Results: According to the calculations, the center had a total of 6,603,479,058 IRR in 2010-2011, of which 49.5% (3,271,089,796 IRR) was allocated for health care expenditure, 20.3% (1,335,186,000 IRR) for research, 12.6% (834,000,000 IRR) for training and 17.6% (1,163,203,262 IRR) for services. The average expense for each person living with HIV was 2276 US dollars. The cost of treatment by drugs for each person eligible for treatment was 782 US dollars.Conclusion: The percentage of budget distribution in the center is equal to the same percentage in low and middle income countries; although, more percentage is allocated for research than the mentioned countries. Also, the expenditure spent for treatment by drugs is more than the average of the same found in low and middle income countries. Overall, the budget distribution in this center is almost in accordance with the international standards
