Fruiting Plant Number in Long-term Study of Population Dynamics of Clarkia xantiana ssp. xantiana at 35 Populations in the Kern River Valley, California, USA from 2006 to 2017
Datafile (Data File Name: “Datafile_Fruiting_Plant_Density.csv) describes the fruiting plant number in quadrats followed on permanent transects for long-term demographic study of Clarkia xantiana xantiana from 2006 to 2017.
At each site, in each year, fruiting plant number was counted in between 30 and 150 0.5 m2 quadrats distributed haphazardly throughout site. The number of quadrats depends on the areal extent of the population. For the 20 populations included in the detailed demography studies, data from 30 permanent plots are included.Documentation of data collected on fruiting plant number per 0.5m2 in long-term study of population dynamics of Clarkia xantiana ssp. xantiana at 35 populations in the Kern River Valley, California, USA from 2006 to 2017National Science Foundatio
Glaucoma Triple Procedure: A One-site vs. a Two-site Approach
The purpose of this study is to describe and evaluate the success rate of combined
glaucoma and small cataract surgery by means of a one-site versus two-site approach.
Fifty-eight eyes of fifty-five patients undergoing combined surgery were operated: thirtyone
eyes underwent two-site approach and twenty-seven eyes underwent one-site approach.
Short term and long term mean intraocular pressure (IOP) was similar in both
groups. There was no significant difference in postoperative inflammation and complication
rates between two groups. There is no significant difference in the postoperative
results in those two different approaches to perform combined operations of cataract
and glaucoma
Fruit Production Per Plant in Long-Term Study of Population Dynamics of Clarkia xantiana ssp. xantiana at 35 Populations in the Kern River Valley, California, USA from 2006 to 2017
The dataset (Data File Name: “Datafile_Fruit_Number_per_Plant.csv”) describes the fruit production per plant for up to 150 plants for each of the 35 populations followed in a long-term demographic study of Clarkia xantiana xantiana in Ker Co., CA.
At each site, in each year, the number of fruits per plant was recorded on up to 150 plants per population. From 2006-2012, fruit number per plant was scored as the sum of undamaged fruits plus the “undamaged fruit equivalents” of damaged fruit. For example, if a plant had 2 damaged fruits, where half of each fruit was missing, the number of undamaged fruit equivalents was scored as 1, and added to the number of undamaged fruits. From 2013-2017, undamaged and damaged fruits were scored separately.Documentation of data collected on fruit production per plant in long-term study of population dynamics of Clarkia xantiana ssp. xantiana at 35 populations in the Kern River Valley, California, USA from 2006 to 2017.National Science Foundatio

Survivorship and Fecundity Data Collected in Long-Term Study of Demography of Clarkia xantiana ssp. xantiana at 20 Populations in the Kern River Valley, California, USA from 2006 to 2017
The datafile (Data File Name: “Datafile_Survivorship_Fecundity.csv) contains data for long-tern study of the demography of Clarkia xantiana xantiana in Kern Co., CA for 20 populations from 2006 to 2017. The dataset includes data on survivorship and fecundity of plants in permanent plots that were followed from germination to fruiting.
At each site, 30 permanent plots of 0.5 m2 were established in 2006 along 4-6 transects. Each year, the number of seedlings in each permanent plot was recorded in February, the number of surviving fruiting plants and the average number of fruits per plant in each plot with fruiting plants were recorded in June.
In 2006, only a subset of permanent plots were monitored for seedling germination, and fruit number per fruiting plant was not recorded.
From 2006-2012, fruit number per plant was scored as the sum of undamaged fruits plus the “undamaged fruit equivalents” of damaged fruit. For example, if a plant had 2 damaged fruits, where half of each fruit was missing, the number of undamaged fruit equivalents was scored as 1, and added to the number of undamaged fruits. From 2013-2017, undamaged and damaged fruits were scored separately.Survivorship and fecundity data collected in long-term study of demography of Clarkia xantiana ssp. xantiana at 20 populations in the Kern River Valley, California, USA from 2006 to 2017.National Science Foundatio
Effect of Parathion-Methyl on Amazonian fish and freshwater invertebrates: a comparison of sensitivity with temperate data.
Parathion-methyl is an organophosphorous insecticide that is widely used in agricultural production sites in the Amazon. The use of this pesticide might pose a potential risk for the biodiversity and abundance of fish and invertebrate species inhabiting aquatic ecosystems adjacent to the agricultural fields. Due to a lack of toxicity data for Amazonian species, safe environmental concentrations used to predict the ecological risks of parathion-methyl in the Amazon are based on tests performed with temperate species, although it is unknown whether the sensitivity of temperate species is representative for those of Amazonian endemic species

Modelling of wall-bounded cavitating flow and spray mixing in multi-component environments using the PC-SAFT equation of state
This work introduces a numerical multiphase model for multi-component mixtures, utilizing tabulated data for physical and transport properties across a spectrum of conditions from near-vacuum pressures to supercritical states. The property data are derived using Perturbed Chain Statistical Associating Fluid Theory (PC-SAFT), vapor-liquid equilibrium (VLE) calculations, entropy scaling methodologies, and Group Contribution (GC) methods. These techniques accurately reflect the thermodynamic behaviors of real fluids, avoiding the empirical estimation of Equation of State (EoS) input parameters. Implemented in OpenFOAM, the fluid dynamics solver is designed to address the three-dimensional Navier-Stokes equations for multi-component mixtures. The methodology integrates operator splitting to manage hyperbolic and parabolic steps distinctively. Hyperbolic terms are solved using the HLLC (Harten-Lax-van Leer-Contact) solver with temporal integration performed via a third-order Strong-Stability-Preserving Runge–Kutta (SSP-RK3) method. Viscous stress tensor contributions in the momentum equation are handled through an implicit velocity correction equation, while parabolic terms in the energy equation are explicitly solved. The simulation efficiency is further enhanced by adaptive Local Time Stepping and the Immersed Boundary (IB) method, which addresses interactions between the fluid and solid boundaries. Turbulence is resolved using the Wall Adaptive Large Eddy (WALE) model. Applied to high-pressure diesel fuel spray injections into non-reacting (nitrogen) gas environments, the model has been validated against Engine Combustion Network (ECN) data for the Spray-C configuration, featuring a fully cavitating multi-hole orifice. Results demonstrate that the model achieves accurate predictions across a broad range of tested conditions without the need for tuning or calibration parameters
