HENSTOCK INTEGRAL AND DINI-RIEMANN THEOREM
2009
In [5] an analogue of the classical Dini-Riemann theorem related to non-absolutely convergent series of real number is obtained for the Lebesgue improper integral. Here we are extending it to the case of the Henstock integral.
Consumer confidence: Causality links with subjective and objective information sources
2020
Abstract This study analyses the relationship of causality between consumer confidence and the economic information ecosystem from subjective (i.e., business sentiment) and objective sources (financial information from listed companies and the stock index). Our sample covers Spain from June 2011 to December 2018. Our results show that consumer confidence and economic information can exert a causality influence on each other. The results show Granger causality from IBEX35 and total assets in the financial sector and leverage of the companies in the energy sector to the consumer confidence index (CCI), in the first lag: from operating income in the telecommunications sector to the CCI in the …
Valor de los Ahorros en Impuestos por Deuda en Colombia: Un Estudio Empírico (Value of Debt Tax Shields in Colombia: An Empirical Study)
2011
The English version of this paper can be found at http://ssrn.com/abstract=1919305This paper estimates the value of tax savings, using the method of discounted cash flows for 23 major industrial firms in the Bolsa de Valores de Colombia (Colombian Stock Market) between 2001 and 2010, showing that this value represents on average between 5.74% and 56.73% out of total firm value depending on discount rate for tax savings. Using Data Panel regressions, it also finds that the average leverage of firms is low relative to other countries. Given this fact, we explored the behavior of the total value of the firm, VT and found no evidence that debt creates value.
Optimizing the Sampling Area across an Old-Growth Forest via UAV-Borne Laser Scanning, GNSS, and Radial Surveying
2022
Aboveground biomass, volume, and basal area are among the most important structural attributes in forestry. Direct measurements are cost-intensive and time-consuming, especially for old-growth forests exhibiting a complex structure over a rugged topography. We defined a methodology to optimize the plot size and the (total) sampling area, allowing for structural attributes with a tolerable error to be estimated. The plot size was assessed by analyzing the semivariogram of a CHM model derived via UAV laser scanning, while the sampling area was based on the calculation of the absolute relative error as a function of allometric relationships. The allometric relationships allowed the structural …
Clinical practice evaluation of opioids induced constipation management in cancer patients: The EIO-Praxis project
2019
Abstract Background In 2017, the ECO Foundation (Excellence and Quality in Oncology) completed the EIO-50 project to learn about the diagnostic and treatment criteria of opioid-induced constipation (OIC) in cancer patients. The EIO-Praxis project was designed as a continuation of EIO-50, to learn about the current clinical practice of oncology professionals for the management of patients with OIC (process, follow-up and results). Methods 77 health care professionals (HCP) from oncology units participated in the study. Each investigator collected information from 10 medical records of cancer patients who received OIC treatment, with a total of 770 records. In each center, 6 indicators of its…

Population structure in Atlantic cod in the eastern North Sea-Skagerrak-Kattegat: early life stage dispersal and adult migration.
2015
Background In marine fish species, where pelagic egg and larvae drift with ocean currents, population structure has been suggested to be maintained by larval retention due to hydrographic structuring and by homing of adult fish to natal areas. Whilst natal homing of adults has been demonstrated for anadromous and coral reef fishes, there are few documented examples of philopatric migration in temperate marine fish species. Results Here, we demonstrate temporally stable genetic differentiation among spawning populations of Atlantic cod (Gadus morhua L.), and present genetic and behavioural evidence for larval drift and philopatric migration in the eastern North Sea-Skagerrak-Kattegat area. W…
Economic performance of biogas plants using giant reed silage biomass feedstock
2015
Abstract With regard to energy crops for the production of raw materials to biomass for biogas plants, has developed a study to determine the optimal minimum size of a biogas plant powered by giant reed (Arundo donax L.) and utilizing livestock waste. In particular, all costs items relating to biomass supply, plant installation and transport costs were analyzed, by changing progressively two main variables: the electrical power capacity and the feedstock utilized (in the range from 100 to 999 kW) and the feedstock utilized, by substituting livestock waste with giant reed silage so as to determine the more economically advantageous option for the entrepreneur in proportion to power capacity …
Economic evaluation of biogas plant size utilizing giant reed
2015
Abstract Amongst energy crops for the production of biomass feedstock for biogas plants, giant reed (Arundo donax L) has been attracting attention in recent years in Italy. Undoubtedly, this is due to its potentially high yield in terms of biomass, low agronomic inputs, as well as for being eligible for European Union energy crop incentives. The aim of this study was to perform an analysis of plant costs considering three macro-categories (biomass, plant installation and transport). Also, we aimed to describe the economic performances of biogas plants, while progressively altering two key variables. Specifically, we considered electrical power capacity (in the 100–999 kW range) and several …
