Understanding consumers' ornamental plant preferences for disease-free and water conservation labels
… plants to address two key issues; plant disease and irrigation water use. A choice modeling survey was utilized to estimate consumers' willingness to pay a premium for six ornamental plants with disease-free and/or water conservation certification labels. The results of the mixed logit …

Fluid and structural modeling of the disease-free and atherosclerotic human carotid bifurcation
Cardiovascular disease is the leading cause of death in the United States. It claims more lives each year than the next 7 leading causes of death combined. Atherosclerosis is a major cause of cardiovascular disease and is an inflammatory process characterized by intimal thickening of arteries and …

Rapid multiplication of cassava (Manihot esculenta Crantz.) as a potential method to provide disease-free plant materials
When explants were cultured for 3 weeks in a double phase medium, with 0.05 $\mu$M gibberellic acid (GA$\sb3$) in LIMO and AMM solid phase, taller (3 cm), single shoots with $>$3.5 roots per explant were produced, while with APM and GA$\sb3$ cultures were shorter, multiple shoots but without roots. …

Control of anthracnose (caused by Colletotrichum gloeosporioides s.l.) on mango in Senegal by fungicides and biofungicides
… molybdate provided 63%, 67% and 76% control of disease severity, respectively, whereas thiophanate methyl and azoxystrobin provided 77% and 78% control, respectively. Disease severities of all treatments were significantly lower than that of the control. Thiophanate methyl and azoxystrobin …

Body mass index and response to neoadjuvant chemotherapy in Korean breast cancer
… factor receptor expression was analyzed. And disease-free survival and overall survival was investigated by recent medical record. According to the WHO classification of BMI, patients divided into four groups less than 18.5, underweight; 18.5 to 24.9, normal weight ; 25 to 29.9, overweight ; …

Mathematical models for Tuberculosis spread in humans
… the next generation method and conditions for disease elimination/persistence are determined. Numerical simulation results show that for the first model, R0 > 1; implying that the disease-free equilibrium is unstable. For the second model, however, R0 < 1; indicating that the disease-free …

Mathematical Modeling, Simulation, and Time Series Analysis of Seasonal Epidemics.
… formulated and analyzed. It is proved that the disease-free steady state of the non-seasonal model is locally asymptotically stable if <em><b>R</b><sub>v</sub></em> < 1, and disease invades if <em><b>R</b><sub>v</sub></em> > 1. For the seasonal SEIRS model, it is shown that the disease-free …

Mathematical epidemiological models with finite time extinction : the case of African swine fever virus in wildlife areas
In Mathematical Epidemiology disease free states are commonly represented as equilibria of dynamical systems which model the respective epidemiological processes. However, in cases when the equilibrium is zero and is related to extinction (of the population), due to the uniqueness property of a …

Treatment outcomes of young patients with invasive breast cancer treated radically at Groote Schuur Hospital from 2013-2017: A single centre study
… Patient characteristics, tumour characteristics, disease stage, treatment, and follow-up were recorded. Primary objectives included evaluating overall and disease free survival, and analysing recurrence patterns and clinicopathological features. Results: The five-year overall and disease free …
