Ash control methods to limit biomass inorganic content and its effect on fast pyrolysis bio-oil stability

This research investigates specific ash control methods to limit inorganic content within biomass prior to fast pyrolysis and effect of specific ash components on fast pyrolysis processing, mass balance yields and bio-oil quality and stability. Inorganic content in miscanthus was naturally reduced over the winter period from June (7.36 wt. %) to February (2.80 wt. %) due to a combination of senescence and natural leaching from rain water. September harvest produced similar mass balance yields, bio-oil quality and stability compared to February harvest (conventional harvest), but nitrogen content in above ground crop was to high (208 kg ha.-1) to maintain sustainable crop production. Deionised water, 1.00% HCl and 0.10% Triton X-100 washes were used to reduce inorganic content of miscanthus. Miscanthus washed with 0.10% Triton X-100 resulted in the highest total liquid yield (76.21 wt. %) and lowest char and reaction water yields (9.77 wt. % and 8.25 wt. % respectively). Concentrations of Triton X-100 were varied to study further effects on mass balance yields and bio-oil stability. All concentrations of Triton X-100 increased total liquid yield and decreased char and reaction water yields compared to untreated miscanthus. In terms of bio-oil stability 1.00% Triton X-100 produced the most stable bio-oil with lowest viscosity index (2.43) and lowest water content index (1.01). Beech wood was impregnated with potassium and phosphorus resulting in lower liquid yields and increased char and gas yields due to their catalytic effect on fast pyrolysis product distribution. Increased potassium and phosphorus concentrations produced less stable bio-oils with viscosity and water content indexes increasing. Fast pyrolysis processing of phosphorus impregnated beech wood was problematic as the reactor bed material agglomerated into large clumps due to char formation within the reactor, affecting fluidisation and heat transfer.

Towards convection-resolving, global atmospheric simulations with the Model for Prediction Across Scales (MPAS) v3.1: an extreme scaling experiment, links to sourcecode of model and grides

The Model for Prediction Across Scales (MPAS) is a novel set of Earth system simulation components and consists of an atmospheric model, an ocean model and a land-ice model. Its distinct features are the use of unstructured Voronoi meshes and C-grid discretisation to address shortcomings of global models on regular grids and the use of limited area models nested in a forcing data set, with respect to parallel scalability, numerical accuracy and physical consistency. This concept allows one to include the feedback of regional land use information on weather and climate at local and global scales in a consistent way, which is impossible to achieve with traditional limited area modelling approaches. Here, we present an in-depth evaluation of MPAS with regards to technical aspects of performing model runs and scalability for three medium-size meshes on four different high-performance computing (HPC) sites with different architectures and compilers. We uncover model limitations and identify new aspects for the model optimisation that are introduced by the use of unstructured Voronoi meshes. We further demonstrate the model performance of MPAS in terms of its capability to reproduce the dynamics of the West African monsoon (WAM) and its associated precipitation in a pilot study. Constrained by available computational resources, we compare 11-month runs for two meshes with observations and a reference simulation from the Weather Research and Forecasting (WRF) model. We show that MPAS can reproduce the atmospheric dynamics on global and local scales in this experiment, but identify a precipitation excess for the West African region. Finally, we conduct extreme scaling tests on a global 3?km mesh with more than 65 million horizontal grid cells on up to half a million cores. We discuss necessary modifications of the model code to improve its parallel performance in general and specific to the HPC environment. We confirm good scaling (70?% parallel efficiency or better) of the MPAS model and provide numbers on the computational requirements for experiments with the 3?km mesh. In doing so, we show that global, convection-resolving atmospheric simulations with MPAS are within reach of current and next generations of high-end computing facilities.

Pelagic phosphorus accumulation in the Pacific Ocean

As a limiting nutrient to marine life, phosphorus (P) is an effective tracer of today's marine productivity. The distribution of P in marine sediments likewise tracks the history of marine productivity because of its relative insolubility in seawater. CaCO3, biogenic opal, terrigenous sediment, and total P have been measured in cores from nine Pacific sites (Deep Sea Drilling Project (DSDP) 65, 66, 310, 77, 62, 572, 463, 586, and GPC-3) and one subantarctic (DSDP 266) site. These sites were specifically chosen to provide information on biota burial flux changes with time for sedimentary sinks that represent key oceanographic variables, i.e., rate of upwelling, water depth, and carbonate dissolution gradient. The accumulation rates of these components for the last 10 Ma were then calculated from determined core age versus depth plots, core bulk density, and porosity data. The accumulation of P weakly correlates with that of CaCO3, moderately with that of total sediment, and very strongly with carbonate-free accumulation. Two prominent peaks for all components occur at 2-3 Ma and 5-6 Ma, and record the chemical loading of dissolved CaCO3, SiO2, and P from glacially emergent continental shelves. These results indicate that continental shelf phosphorites form during interglacially high sea levels and correspond to low deep-sea P accumulation rates, whereas glacially lowered sea levels allow for shelf bypassing and greater deep-sea P accumulation rates.

Validación de curvas antropométricas de crecimiento intrauterino: Hospital Vicente Corral, Cuenca, Ecuador, 2013

Se realizó un estudio transversal en el Hospital Vicente Corral de Cuenca (Ecuador) en febrero-agosto de 2013, para la valoración de las curvas intrauterino del Centro Latinoamericano de Atención Perinatal (CLAP), Olsen, Alarcón-Pittaluga, Lubchenco-Bataglia y Babson-Benda con el objetivo de identificar el patrón antropométrico de crecimiento fetal más adecuado para la clasificación de los recién nacidos hasta que el Ecuador cuente con patrones propios. La muestra se conformó con neonatos, cuyas madres eran menores de 21 años. Se incluyó a niños nacidos vivos, con edad gestacional entre 22 y 42 semanas cumplidas y que contaron con todas las medidas antropométricas. Se excluyó a niños con malformaciones congénitas mayores. Se valoraron la sensibilidad, especificidad e índice kappa de Cohen de las curvas antropométricas estudiadas según las variables peso, talla, perímetro cefálico y sexo del recién nacido. Las curvas del CLAP (36.6-43.5%) y de Olsen (37.0-40.9%) identificaron porcentajes similares de PEG15. Las curvas de Babson-Benda detectaron muy pocos PEG (1.3-2.8%). Para la variable peso: las curvas de Olsen presentaron alta sensibilidad (81.8-97.6%), muy altas especificidad (91.8-97.5%) e índice kappa (0.807-0.873). Las curvas de Alarcón-Pittaluga tuvieron muy buena sensibilidad (98.2-99.5%); buena especificidad (74.9-77.9%) e índice kappa (0.707-0.717). Las curvas de Lubchenco-Bataglia presentaron baja sensibilidad (40.0-42.8%), muy buena especificidad (99.3-100.0%) y moderado índice kappa (0.449-458). Las curvas de Babson-Benda presentaron muy baja sensibilidad (3.5-6.4%), muy buena especificidad (100.0%) y pobre índice kappa (0.044-0.072). Se concluye que se deben utilizar las curvas antropométricas de Olsen hasta que el Ecuador cuente con curvas propias. No se recomienda utilizar las curvas de Babson-Benda ni de Lubchenco-Bataglia.

Function Analysis of Milk Yield on Small Holder Dairy Cattle in Sumbang Banyumas Region

A survey on smallholder dairy cow had conducted in Banyumas region from November 8th 1999 up to February 8th 2000. Forty six respondents were involved in this study (as samples). Cobb - Douglas analysis was applied in this survey. From the study can be concluded that a small holder owned 3.02 heads of dairy cow (2.2  ST), 1.44 heads of lactating cow with 9.77 L/day milk production on average. The benefit of the backyard farming was RP.70.603,225 per month on average. Feeding was the biggest influence on benefit because feed cost was 65.81 percent from the production cost. The milk production function , by the equation: Y = 0,8958 X1⁰·⁰³³² X2 0.049 X30.168 X40.608 The four variables can explain 92.4 percent (R²=0,924)on the milk  production variation .It can be suggested that to improve milk production on dairy cows can be done by intensifying labour, and improving the forage feeding.
