Trends and the Current Status of Living Donor Liver Transplant

The need for liver transplant and its timely nature are both equally vital for a patient with end stage liver disease. But the ever-growing need for liver transplant across the entire world threatens the two reasons that justify its very existence. The popularity of living donor liver transplant has met great enthusiasm amongst the transplant physicians and surgeons, as it is timely, and also yields superior survival benefit as compared to a deceased donor liver transplant. Living donor liver transplant has been constantly adapting to meet the needs of patients and the expanding wait list. The need for a living donor liver transplant is not the same amongst the various parts of the world, because the population and the disease burden is different. We looked at the trend of living donor liver transplant across the world and also the change in practices over time including a glimpse of what lies ahead for the next decades

A hydrogeochemical review of riverine mine tailings deposition at Freeport Indonesia

This study is carried out at PT Freeport Indonesia (PTFI), one of the world’s largest copper‐gold mines. Due to steep terrain, high intensity rainfall and seismic activity, and after exhaustive studies, years of planning and engagement with government and other stakeholders, a controlled river tailings management system has been adopted to transport the tailings as the only feasible system. The tailings are transported to an engineered deposition area in the lowlands and coastal zones called the Modified Deposition Area (ModADA). Understanding the long‐term geochemical stability of the deposited tailings is critical for tailings management. As such, the study aims to evaluate the performance of a geochemically managed discharge approach under tropical climatic conditions by studying the relationships between geomorphic setting, geochemical processes and fate of carbonate‐rich sulphidic mine tailings transported via the river. The result of this study indicates that the ore‐feed blending strategy applied by PTFI has achieved the objective of ensuring that there will be no or minimal acid generation resulted from tailings deposition in ModADA.\ua0\ua

Hydrogen Enriched Natural Gas as a Clean Motor Fuel (CONTINUATION OF 7863 ABANDONED)

A fuel mixture is disclosed. In a preferred embodiment, an alternative gaseous fuel for operating a combustion engine includes approximately 21 to 50% Hydrogen and the rest natural gas constituants such as combinations of Methane, Carbon Dioxide, Nitrogen, Ethane, Propane, Iso-Butane, N-Butane, Iso Pentane, N-Pentane, and Hexanes Plus. Current production engines without any substantial modifications can take this alternative fuel. This alternative fuel is lean burning and emits emissions that are below current legal standards

Hydrogen Enriched Natural Gas as a Motor Fuel with variable Air Fuel Ratio and Fuel Mixture Ratio Control (CIP OF 7863 ABANDONED)

A hydrogen and natural gas fuel mixture for internal combustion engines is provided for vehicle engines such as those used in standard production engines for automobiles, trains and lawn mowers. The gaseous fuel for operating a vehicle combustion engines includes approximately 21 to 50% Hydrogen and the rest natural gas constituents such as combinations of Methane, Carbon Dioxide, Nitrogen, Ethane, Propane, Iso-Butane, N-Butane, Iso Pentane, N-Pentane, and Hexanes Plus. A fuel mixture of approximately 28 to 36 percent Hydrogen and a air fuel equivalence ratio of approximately 0.625 is an extreme lean burn condition that yields hydrocarbon emission levels of less than approximately 104 ppm (0.84 hm/hp hr.). Current internal combustion engines that are in mass production can take this alternative fuel without any substantial modifications to their systems. This alternative fuel is lean burning and emits emissions that are below current legal standards. The novel fuel mixture can be use

The Impact of Spatial Heterogeneity in Land Use Practices and Aquifer Characteristics on Groundwater Conservation Policy Cost

Estimation of agricultural policy cost for a given level of groundwater conservation requires the establishment of an accurate baseline condition. This is especially critical when the benefits and cost of any conservation program are generally estimated relative to the status quo policy or baseline situation. An inaccurate baseline estimate will lead to poor estimates of potential water conservation savings and agricultural policy cost. Over a 60-year planning horizon per acre net present value is as much as 29.8% higher for a study area when aquifer characteristics are assumed to be homogenous and set to their average area value than when the heterogeneity in aquifer characteristics is explicitly modeled.Aquifer Modeling, Economics, Resource /Energy Economics and Policy,
