Using the modified Hirsch model and the Sliver Test to forward calculate asphalt mixture complex modulus and backward calculate asphalt binder complex modulus
No full textProtecting our asphalt pavements structures from possible distresses such as pavement cracking and pavement rutting require good understanding of materials used to construct pavement structures. When conducting QA/QC or a forensic analysis to characterize asphalt materials that were used on existing roads and highways requires extensive number of cores to be taken per section. The coring process will initiate cracks in the coring location, which will propagate later on and may lead to the formation of alligator cracks and potholes. Many of the currently utilized test apparatus utilize a minimum of a 6-inches core to provide a sample large enough to test. Sample preparation after coring is limited further by lift thickness; to not test a composite material one must cut the field core sample to ensure only one pavement lift is being tested. If the pavement design specifies a lift that is less than the minimum size for current test apparatus, no testing can be completed on that sample. Incorporating recycled asphalt materials and shingles in mixture designs makes it even more challenging to characterize combined asphalt mixture properties. The combination of virgin and recycled asphalt requires the development and implementation of material testing methods that can test asphalt mixtures in the solid form. Labs that are interested in studying the impact of aging, time, and temperature on the commingling of RAP and/or shingle asphalt on the stiffness modulus of bituminous mixtures find it difficult to use current asphalt mixture performance tests. This is due to different reasons such as time-consuming performance testing process, samples size, and test/analysis complexity. In this research, a new methodology was developed to simplify and expedite forensic testing. The developed methodology addressed previously mentioned asphalt mixture performance testing issues. The developed methodology consists of two main tools. A new test procedure using the Sliver Test ASTM D7552. A forward and backward models based on the modified Hirsch model developed by, Christensen et al, currently being used in the pavement design guide. The developed methodology successfully analyzed asphalt mixture and asphalt binder response parameters from the sliver test output. Developed methodology successfully helped forward calculate asphalt mixture complex modulus and backward calculate asphalt binder complex modulus avoiding asphalt binder chemical extraction process. The methodology was developed using 700 data points then verified using a total 1050 data points. Statistical goodness of fit parameters and coefficient of variance was performed. Results showed promise and the methodology was able to forward calculate asphalt mixture (R^2>95.5%) and asphalt binder complex modulus (R^2>87%).Ph.D.Includes bibliographical referencesby Mohamed Monir Hagga

Management of inland open water fisheries resources of Bangladesh : Issues and options
Get PDFDespite the possession of a highly productive inland water area of about 45,000 km2, the continuing decrease in fish catch increasingly threatens the livelihoods of more than 12 million fishers in Bangladesh. The government's open access and leasing policies have been identified as the principal causes of catch decline. Conflicting demands on the inland aquatic area also accelerate drastically the destruction of aquatic resources. Barriers to the access of fishers in the management of inland fisheries resources and over-exploitation by the relatively wealthier non-fisher population are reducing the options for sustaining the livelihoods of fishery dependent communities. The government has pursued a range of initiatives to arrest this continued decline but none has appeared to be appropriate. In this study we investigated the present fisheries management crisis of Bangladesh and justified the opportunities for existing fisheries management to evolve towards community based fisheries management (CBFM) to support the sustainable use of fisheries resources in future
Bed utilization pattern of intensive care units affiliated to Ministry of Health: a national study in Egypt prior to the COVID-19 pandemic
Get PDFBACKGROUND: This study aims to calculate the following bed utilization of intensive care Units (ICU) at the national and regional levels. METHODS: A descriptive retrospective record-based study was done in all ICUs affiliated to Ministry of Health and Population (MOHP). RESULTS: ICU admission rate ranged from 0.09% to 0.41% with 0.19%. BOR ranged from 10% to 72% with 60%. The ALS (Days) ranged from 1.92 days to 5.41 days with 3.61 days. The average ABTI per year ranged from 1.42 days to 25.04 days with 2.46 days. The average ABTR ranged from 13.14 to 101.02 with 60.14. CONCLUSIONS: Utilization of ICUs affiliated to MOHP is not optimal at the national level and there is a room for improvement
