Symptom variability and control in COPD: Advantages of dual bronchodilation therapy

2017

Abstract Background Chronic obstructive pulmonary disease (COPD) is a heterogeneous disorder characterized by usually progressive development of airflow obstruction that is not fully reversible. While most patients will experience symptoms throughout the day or in the morning upon awakening, many patients do not experience their symptoms as constant but report variability in symptoms during the course of the day or over time. Symptom variability adversely affects patients' health status and increases the risk of COPD exacerbations. Methods We examined data from the literature on symptom variability and control in patients with COPD, with focus on the use of inhaled bronchodilator therapy wi…

Food-grade argan oil supplementation in molasses enhances fermentative performance and antioxidant defenses of active dry wine yeast

2015

The tolerance of the yeast Saccharomyces cerevisiae to desiccation is important for the use of this microorganism in the wine industry, since active dry yeast (ADY) is routinely used as starter for must fermentations. Both biomass propagation and dehydration cause cellular oxidative stress, therefore negatively affecting yeast performance. Protective treatments against oxidative damage, such as natural antioxidants, may have important biotechnological implications. In this study we analysed the antioxidant capacity of pure chemical compounds (quercetin, ascorbic acid, caffeic acid, oleic acid, and glutathione) added to molasses during biomass propagation, and we determine several oxidative …

Thermodynamic properties of a liquid–vapor interface in a two-component system

2010

Abstract We report a complete set of thermodynamic properties of the interface layer between liquid and vapor two-component mixtures, using molecular dynamics. The mixtures consist of particles which have identical masses and diameters and interact with a long-range Lennard-Jones spline potential. The potential depths in dimensionless units for like interactions is 1 (for component 1) and 0.8 (for component 2). The surface excess entropy decreases when the temperature increases, so the surface has a negative excess heat capacity. This is a consequence of the fact that the surface tension decreases to zero at the critical point, proportional to ( T C , i − T ) 2 ν . The surface entropy decre…

Thermodynamic properties of N-octyl- and N-dodecylnicotinamide chlorides in water

1990

Densities, heat capacities and enthalpies of dilution at 25°C and osmotic coefficients at 37°C were measured for N-octyl- and N-dodecylnicotinamide chlorides in water over an extended concentration region. Partial molar volumes, heat capacities, relative enthalpies and nonideal free energies and entropies at 25°C were derived as a function of the surfactant concentration. For both surfactants, plots of volumes, enthalpies and free energies vs. concentration are regular whereas those of heat capacities and entropies present anomalies at about 0.8 and 0.1m for the octyl and dodecyl compounds, respectively. Changes in the slope of a plot of osmotic coefficients times molality vs. molality were…

Intellectual Capital and Company Value

2014

AbstractThe bulk of traditional corporate valuation methods reflect historical performance, while it is necessary to also take into consideration the value which is off-balance-sheet and possible growth. Large differences exist between company market and book value, and a part of this can be explained by intellectual capital. The aim of the study is to make an empirical investigation of the impact of intellectual capital on company value. Empirical results show that one can find mixed results regarding relationship between value added intellectual coefficient VAICTM and company value.

Intellectual Capital Report in the Healthcare Sector: An Analysis of a Case Study

2017

In the healthcare sector the growing interest in intellectual capital begins with the understanding that the ability to maintain and develop knowledge within it is one of a major reason for the success of the structure. Knowledge presents in health care organizations is a valuable asset, essential to ensure a good quality of services, which has been not only enhanced but also continuously developed. In this sense, analyzing the intellectual capital in healthcare means put at the centre of attention knowledge, the processes that make it possible. This exploratory study aims to investigate the importance of intellectual capital in the healthcare sector, thorough the examination and interpreta…

Assessing drought vulnerability and adaptation among farmers in Gadaref region, Eastern Sudan

2018

Agricultural productivity in rural areas is severely affected by climate variability, and this elevates the vulnerability of rural households to food insecurity. This study examines the socio-economic vulnerability of farmers who are susceptible to droughts in the five agricultural-based regions of Gadaref, Eastern Sudan. A survey was carried out in 500 households to collect data on socio-economic and livelihood indicators. The data analyzed from these indicators were used to generate the three components of drought vulnerability: exposure, sensitivity and adaptive capacity. The analysis revealed that the regions deemed to be most vulnerable to both drought and climate variability were also…

Assessment of vulnerability and adaptive capacity to coastal hazards in the Caribbean Region

2014

ABSTRACT Lam, N.S.N., Arenas, H., Brito, P.L., Liu, K.B., 2014. Assessment of vulnerability and adaptive capacity to coastal hazards in the Caribbean region. In: Green, A.N. and Cooper, J.A.G. (eds.), Proceedings 13th International Coastal Symposium (Durban, South Africa), Journal of Coastal Research, Special Issue No. 70, pp. 473–478, ISSN 0749-0208. It has been documented that given the same type of climate related hazard and degree of exposure, the vulnerability of a region to the hazard and its resultant damages could be very different, depending on a number of natural and socioeconomic factors. An understanding of the factors contributing to the vulnerability of a region requires a goo…

Follow‐up of patients subjected to direct and indirect pulp capping of young permanent teeth. A retrospective study

2021

Abstract Objective A retrospective study of the success rate of direct pulp capping (DPC) and indirect pulp capping (IPC) was carried out in children between 6–14 years‐old, considering separately primary caries or caries affecting teeth with molar incisor hypomineralization (MIH). Material and methods Data were collected in a dental public health service. Following the inclusion criteria, 232 treatments were analyzed. Success was defined by the presence of a functional tooth without clinical signs or symptoms of pulpal or periapical disease. The success rate was correlated to patient gender, the affected tooth and the indication of therapy using the chi‐squared and Fisher exact test. The s…
