Stereoselective Synthesis of the Antiprotozoal Lactone Passifloricin A and Seven Isomers Thereof
2004
The conjugated delta-lactone passifloricin A, a natural product with antiprotozoal activity, and seven isomers thereof have been synthesized in enantiopure form. It has been shown in this way that the proposed structure for the natural compound was erroneous. The correct structure is now evidenced. Key steps of the syntheses were asymmetric Brown-type aldehyde allylations and ring-closing metatheses.

On automatic algorithm configuration of vehicle routing problem solvers
2019
Many of the algorithms for solving vehicle routing problems expose parameters that strongly influence the quality of obtained solutions and the performance of the algorithm. Finding good values for these parameters is a tedious task that requires experimentation and experience. Therefore, methods that automate the process of algorithm configuration have received growing attention. In this paper, we present a comprehensive study to critically evaluate and compare the capabilities and suitability of seven state-of-the-art methods in configuring vehicle routing metaheuristics. The configuration target is the solution quality of eight metaheuristics solving two vehicle routing problem variants.…
A Dynamic Electrical Scheme for the optimal reconfiguration of PV modules under non-homogeneous solar irradiation
2012
This paper presents a strategy for the maximization of the output power of photovoltaic (PV) systems under non homogeneous solar irradiation by means of automatic reconfiguration of the PV arrays layout. The innovation of the proposed approach is the employment of a simple Dynamic Electrical Scheme (DES), allowing a large number of possible modules interconnection, to be installed between the PV generator and the inverter. The models of the PV generator and of the DES have been realized and simulated with Simulink (Dynamic System Simulation for MATLAB). The attained experimental results appear to be quite interesting in terms of the attainable benefit in power and thus energy terms. The lim…
Mobile Technology Adoption and the Effects of Cultural Factors
2019
Mobile technologies are an important part of human life in both the personal and professional realms. Many services (banking, news, health, education, etc.) that traditionally offered either face-to-face, telephone, or other conventional platforms and technologies are now establishing services on mobile platforms as well. Mobile gadgets are now also being used by company employees as sales automation tools. The importance of culture in technology adoption and usage has been well-established. The adoption of any technology includes a set of factors that determine if the technology is either accepted or rejected, and the individual strengths of these determining factors may vary greatly, depe…
Evidence of neonatal memory of odor configuration
2013
The perception of some mixtures of odorants engages configural abilities, i.e. the perception of these mixtures as single odor objects. For instance, data in human adults demonstrated that a mixture of two odorants (AB), one smelling like strawberry and the other like caramel, generates the configural perception of the odor of pineapple (Le Berre et al., 2008; Barkat et al., 2012). Configural processing may be adaptive also for young organisms, to which rapid extraction of chemical information from the maternal environment, highly complex, is a prerequisite to survival. Thus, results in newborn rabbits suggest the perception of a unique odor in the AB mixture (smelling like configural pinea…
SAP konfigurēšanas iespēju izmantošana uzņēmuma biznesa procesu atbalstam
2016
Jebkuras organizācijas darbība balstās uz vairāk vai mazāk strukturētiem procesiem, jo neviens nemēģina sasniegt iecerētos rezultātus, katru reizi izmantojot citus līdzekļus, bet gan izmanto jau pārbaudītas pieejas. Un ja organizācija nodarbojas ar biznesa procesu realizēšanu SAP sistēmā, tad katram biznesa procesam ir nepieciešama iestatījumu konfigurācija sistēmā. Darbā tiek aplūkota SAP sistēmas konfigurēšana, lai to pielāgotu organizācijas biznesa procesiem un no tās izejošas problēmas ar iespēju tos atrisināt.

Computation of the regime configuration of a meandering stream
2004
Regime channel formation is a delicate adaptation to the imposed environmental conditions compatible with flow and sediment transport mechanisms. The present paper concerns the computation of the regime configuration of a meandering stream. It is supposed that the channel develops until it reaches the state of “final thermodynamic equilibrium”, where the ratio of the kinetic energy of the flow to its cross-sectional potential energy is minimum. An optimization procedure that allows the analysis of the regime channel formation is presented and it is checked using a real case.
