Heterogeneous Photocatalysis for Selective Formation of High-Value-Added Molecules: Some Chemical and Engineering Aspects
2018
This review deals with the parameters that influence heterogeneous photocatalysis (PC) for selective synthesis of high-value chemicals by itself or in combination with other technologies. In particular, the parameters related to the photocatalysts, such as crystallinity degree, type of polymorph, surface acid-base properties, exposure of particular crystalline facets, coupling of different semiconductors, position of the valence and conduction band edge, addition of doping agents, and those related to the reaction system, such as setup configuration and reactor geometry, type of solvent, type and amount of photocatalyst, affecting the selectivity toward specific products are described and d…
Human Resources – A Value Driven Perspective
2019
The information age has changed many of the “classical” business activities by altering the core values and management principles. Human resources management has also changed and has adapted to the new challenges of the 21st -century information age. The hunt for knowledge and for the determined business value is driven by more complex and far-reaching human resources activities. Companies must change their “classic” view on human resources to prevail and to be successful in the new complex and speed century. Human resources have changed its old working principles to fit the requirements of constant data, information, and knowledge “hunting” and morphed to a proactive and dynamic business v…
The dynamics of Italian competitive positioning in the Mediterranean Bluefin tuna industry
2020
The bluefin tuna or Thunnus thynnus is one of the widely recognised fish species since ancient times. Italy is the most important players in the international arena, however, the introduction of a system of total allowable catches and other measures established by the International Commission for the Conservation of Atlantic Tunas, has deeply changed the competitive positioning of Italy. The aim of this study is to perform an analysis of the comparative advantage of Italy by using the relative trade advantage index. Findings reveal that Italy has gained a competitive advantage in the Maltese market and has suffered a loss of the historical competitive advantage in the Japanese one. Results …
Rompé tus barreras: Un análisis sobre el uso del coaching ontológico en la plataforma de entrenamiento de Nike en Buenos Aires
2020
In recent times, coaching has become relevant in heterogeneous discourses and practices in the economic, political and cultural fields of contemporary societies. Based on our ethnographic analysis of different training sessions on the Nike+ Run Club platform in Buenos Aires, in this article we study how ontological coaching operates in the field of sport and races. Then, we ask about how people who attend this platform appropriate coaching techniques to manage emotions, moods, and body effects according to the business entrepreneurship logic. Through this work, the ethnographic results are articulated with a reflection about the theory, practice, and values of the ontological coaching, wher…
Optimality of Increasing Stability for an Inverse Boundary Value Problem
2021
In this work we study the optimality of increasing stability of the inverse boundary value problem (IBVP) for the Schrödinger equation. The rigorous justification of increasing stability for the IBVP for the Schrödinger equation were established by Isakov [Discrete Contin. Dyn. Syst. Ser. S, 4 (2011), pp. 631--640] and by Isakov et al. [Inverse Problems and Applications, Contemp. Math. 615, American Math Society, Providence, RI, 2014, pp. 131--141]. In [Discrete Contin. Dyn. Syst. Ser. S, 4 (2011), pp. 631--640] and [Inverse Problems and Applications, Contemp. Math. 615, American Math Society, Providence, RI, 2014, pp. 131--141], the authors showed that the stability of this IBVP increases …
Investigating the Impact of Organizational Culture on Information Security Policy Compliance : The Case of Ethiopia
2021
Information security is one of the organizations' top agendas worldwide. Similarly, there is a growing trend in the kinds and rate of security breaches. Information security experts and scholars concentrate on outsiders' threats; conversely, insiders are responsible for most of the security breaches in organizations. Further, the majority of information security research findings are limited to solutions that are technically focused. However, it is now recognized that the technological approach alone does not carry the security level needed. So this led researchers to embark on socio-technical approaches. Thus, this study explores organizational culture's effect on employees' intention to c…
Dangerous relationships : biases in freshwater bioassessment based on observed to expected ratios
2018
Copyright by the Ecological Society of America The ecological assessment of freshwaters is currently primarily based on biological communities and the reference condition approach (RCA). In the RCA, the communities in streams and lakes disturbed by humans are compared with communities in reference conditions with no or minimal anthropogenic influence. The currently favored rationale is using selected community metrics for which the expected values (E) for each site are typically estimated from environmental variables using a predictive model based on the reference data. The proportional differences between the observed values (O) and E are then derived, and the decision rules for status ass…
Myocardial Glutathione Alterations in Acute Coronary Occlusion in the Dog
1987
Glutathione (GSH) decreases in dog mycocardium upon acute coronary occlusion when compared with sham-operated dogs. Total glutathione content (GSHeq = GSH + ZGSSG) remains unchanged throughout the experiment (6 h after surgery) in both sham- and acute coronary occlusion-operated dogs. GSSG and GSH/GSSG ratio increases and decreases respectively in all animals but tends to reach the normal value after 6 h in sham-operated dogs. Both parameters (GSSG and GSH/GSSG ratio) remain altered in acute coronary occlusion-operated ones. This alteration of glutathione status in ischemic myocardium is discussed.
Current transformers effects on the measurement of harmonic active power in LV and MV networks
2011
The harmonic active power is used to determine the location of polluting loads, the direction of harmonic power flow and to estimate how consequential a certain current harmonic source is. The highest uncertainties, when measuring harmonic active power, are introduced by the current and voltage transducers. This paper presents experimental results which show the impact of current transformers (CTs) on the accuracy of the harmonic power measurements. An expression for the evaluation of the power error in distorted conditions was developed which can be easily utilized in the case of linear current transducers. It is shown how CTs cannot be considered linear transducers and how the higher the …
Boundary value problem with integral condition for a Blasius type equation
2016
The steady motion in the boundary layer along a thin flat plate, which is immersed at zero incidence in a uniform stream with constant velocity, can be described in terms of the solution of the differential equation x'''= -xx'', which satisfies the boundary conditions x(0) = x'(0) = 0, x'(∞) = 1. The author investigates the generalized boundary value problem consisting of the nonlinear third-order differential equation x''' = -trx|x|q-1x'' subject to the integral boundary conditions x(0) = x'(0) = 0, x'(∞) = λ∫0ξx(s) ds, where 0 0 is a parameter. Results on the existence and uniqueness of solutions to boundary value problem are established. An illustrative example is provided.
