We present the first comprehensive investigation of the concentrations, fluxes and sources of aerosol trace elements over the Gulf of Aqaba. We found that the mean atmospheric concentrations of crustally derived elements such as Al, Fe and Mn (1081, 683, and 16.7 ng m¯³) are about 2–3 times higher than...
The body size (W) of animal species is one of the best predictors of
population density (D) when large assemblages are considered. It has been
shown that theoretically the D-W relationship can be the consequence of two
other distributions: the log-normal distribution of body sizes of the species and
of...
This dissertation used land rent theory and an economic model of land-use conversion to examine the main drivers of the deforestation occurred in Antioquia,Colombia, between 1980 and 2000. Land-cover information at a semi-fine scale (1:25,000)
obtained largely from aerial photography was employed to calculate deforestation. In addition, free international databases...
A casein agar diffusion method was developed to detect and quantify pertinent
levels of proteinases produced in raw milk supplies by heat resistant Bacillus
sporeformers. In order to optimize the required heat treatment conditions of raw milk
samples, trials that involved a combination of different temperatures and times were
evaluated....
Effects of stochastic variations of parameters in the planning
and design of a particleboard production system are studied. The
solution obtained from a linear deterministic optimization model is
compared against both the solution derived from the traditional
stochastic programming techniques and the distribution of optimal
objective function values obtained from...
The code is developed for the calculation of the magneto-crystalline anisotropy (MAE) in thin films using a classical Heisenberg hamiltonian with a correction developed by Van Vleck. A Metropolis style Monte Carlo algorithm was used with adequate corrections to accelerate the calculation. The MAE was calculated for the case of...
The biochemical and organoleptic changes that took place in
raw whole Pacific shrimp and in the cooked meat during eight days
of iced storage were investigated.
A steady increase of both microbial numbers on the raw shrimp
and pH in the raw shrimp and cooked meat was observed.
The levels...
Ever since composite laminate technology was introduced into the aerospace and automotive industry, there has been a need to fully understand the damage progression experienced by composite laminated plates in the presence of a notch. While numerous research studies have been conducted on this matter when subjected to in-plane loads,...
Two experiments were conducted each with 768 Deka lb XL Single Comb
White Leghorn (SCWL) laying pullets for nine and eight 28-day periods to evaluate
the feeding value of yellow pea (YP) (Pisum sativum L. var. Miranda) without and
with, respectively, either 1.5 or 5% meat and bone meal (MB)...
Mass transfer processes in food systems, such as solute infusion, are poorly understood because of their complex nature. Food systems contain porous matrices and a variety of continuous phases within cellular tissues. Mass transfer processes are generally not pure diffusion: often convection, binding and obstructing diffusion will occur. Monte Carlo...
The validation and potential use of mathematical models to estimate the
shelf-life of refrigerated food exposed to temperature abuse and basing such
estimations on microbial growth was analyzed. Combined heat transfer, microbial
growth models, and non-parametric statistical procedures formed a computer-based
predictive tool to assess shelf-life and estimate the accuracy...
During the last 10 years or so, enormous amounts of money
have been invested in Manzanillo for several new installations
and improvement of others. Some of the most important are the
building of the thermoelectric power plant, the development of
the interior port, construction of new highways, exploitation of
iron...
In this paper we consider the total space of the canonical bundle of P² and we use a proposal by Hosono, together with results of Seidel and Auroux–Katzarkov–Orlov, to deduce the physical mirror equivalence between D[superscript b][subscript P²] (K[subscript P²]) and the derived Fukaya category of its mirror which assigns...
The fossil species Arrhinolemur scalabrinii, which was described from late Miocene deposits of Entre Ríos, Argentina, is reevaluated. Whereas the species was originally placed in the Primates (Mammalia) and later made the unique member of the order Arrhinolemuroidea within the Mammalia, our analysis indicates that the specimen is rather a...
In October 2007 the NOAA ship Ronald H. Brown sailed southward within 300 km of the coast of Ecuador and Peru, sampling surface meteorology, air–sea turbulent and radiative fluxes, cloud properties, and upper-air soundings from the equator to 20°S. Two distinct water masses characterize the coastal region: cold-pool water below...
The EU framework for the collection and management of fisheries data (EU Reg. 1004/2017) requires estimates of four variables related to capital value and capital cost of fishing fleets, i.e. Consumption of fixed capital, Value of physical capital, Value of quota and other fishing rights, Investments in tangible assets. The...
Conjugated linoleic acid (CLA) has been recently studied for its health-promoting and disease-preventing properties. The objective of this study was to evaluate the effect of pressure (100-600 MPa), temperature (60-120˚C) and treatment time (0-14 min) on CLA content in milk and anhydrous milk fat (AMF) rich in CLA. In milk...
Cloud radars at X, Ka and W-bands have been used in the past for ocean studies of clouds, but the lack of suitable stabilization has limited their usefulness in obtaining accurate measurements of the velocity structure of cloud particles and the heights of cloud features. A 94 GHz (W-band) radar...
Previous studies have reported that the metastable vaterite phase of calcium carbonate can be stabilized in solution by acidic additives. Here we demonstrate that vaterite can also be stabilized directly at surfaces by engineered peptides. Our data show that the mineralisation occurs in a 'self-templating' process where calcium ions restructure...
