Methane Generation Using an Anaerobic Biodigester From Waste Leachate Water

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Leachate wastewater (LWW) is characterized by slow biodegradation and low biogas production due to resistant materials and limited biological activity. Therefore, applying pretreatments is essential to improving biodegradation potential, which consequently boosts energy recovery.

Linear-Gompertz Model-Based Regression of Photovoltaic Power Generation by Satellite Imagery-Based Solar Irradiance

open access: yesEnergies, 2020
A simple yet accurate photovoltaic (PV) performance curve as a function of satellite-based solar irradiation is necessary to develop a PV power forecasting model that can cover all of South Korea, where more than 35,000 PV power plants are currently in ...

A reaction-diffusion model for the growth of avascular tumor

open access: yes, 2001
A nutrient-limited model for avascular cancer growth including cell proliferation, motility and death is presented. The model qualitatively reproduces commonly observed morphologies for primary tumors, and the simulated patterns are characterized by its ...

On Bivariate Exponentiated Extended Weibull Family of Distributions [PDF]

open access: yes, 2015
In this paper, we introduce a new class of bivariate distributions called the bivariate exponentiated extended Weibull distributions. The model introduced here is of Marshall-Olkin type.

Polylimonene Improves the In Vivo Wound Healing Performance of Sodium Alginate‐Based Hydrogels

open access: yesJournal of Applied Polymer Science, EarlyView.
An oligomer derived from orange peel essential oil incorporated into an alginate hydrogel was shown to be biocompatible and to exhibit a high capacity for in vivo incisional wound healing, as confirmed by experimental assays and mathematical models fitted to the data describing wound area reduction as a function of the dressing‐tissue contact time ...

Evidence for the Gompertz Curve in the Income Distribution of Brazil 1978-2005

open access: yes, 2008
This work presents an empirical study of the evolution of the personal income distribution in Brazil. Yearly samples available from 1978 to 2005 were studied and evidence was found that the complementary cumulative distribution of personal income for 99%

Broadband modelling of short gamma-ray bursts with energy injection from magnetar spin-down and its implications for radio detectability [PDF]

open access: yes, 2015
The magnetar model has been proposed to explain the apparent energy injection in the X-ray light curves of short gamma-ray bursts (SGRBs), but its implications across the full broadband spectrum are not well explored.

Why we age

open access: yesBiological Reviews, EarlyView.
ABSTRACT Three categories of explanations exist for why we age: mechanistic theories, which omit reference to evolutionary forces; weakening force of selection theories, which posit that barriers exist that prevent evolutionary forces from optimising fitness in ageing; and optimisation theories, which posit that evolutionary forces actually select for ...

Longitudinal Tumor Size and Survival Modeling for Exposure–Response Analysis of Drugs with Frequent Dose Reductions: Dose Justification of Abemaciclib in Patients with Metastatic Breast Cancer

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Abemaciclib is an oral anticancer drug indicated for treatment of HR+ HER2‐ breast cancer. Dose modifications due to side effects are frequent, thus drug exposures change over time as a result of altering the dose or temporarily withholding abemaciclib treatment.

The Log-Expo Inverse Gompertz Distribution: properties and Estimations [PDF]

open access: yesMaǧallaẗ Al-Buḥūṯ Al-Mālīyyaẗ wa Al-Tiğāriyyaẗ
This paper introduces the Log-Expo Inverse Gompertz Distribution (LET-IG) three-parameter distribution and examines some of its mathematical properties. The study derives the density distribution, reliability function, and hazard rate function.
