Essential oils as antibacterial agents
An alarm increase in the rate of emerging of resistant bacteria have been causing a great public concern worldwide. This problem of increasing resistance has necessitated the search for safe and effective factors that may be used to treat persistent bacterial infections or modify the currently available antibiotics. An experimental approach, using agar diffusion method was used to estimate the antibacterial properties of 5 essential oils (cinnamon, clove, peppermint, rosemary and thyme) each one individually, in pure and commercial form, against 3 of the bacterial strains that cause common skin infections which are gram negative bacteria (Escherichia coli, Pseudomonas aeruginosa) and gram positive bacteria (Staphylococcus aureus), obtained from clinical sources. Only two of the commercial oils had an antibacterial effect on both gram negative bacteria (E. coli) and gram positive bacteria (S. aureus) and in lesser extent on gram negative bacteria (P. aeruginosa).synergy.

Essays on congruence theory in marketing : Special focus on digital products and webstores
Digital products are intangible goods, mainly presented visually and acoustically to consumers in the form of videos, images, texts, and music that can be bought, downloaded, or streamed via various web stores. Their consumption primarily fulfills hedonic needs. Before purchasing, a consumer's interaction with a digital product is always mediated by technology. Therefore, consumers cannot directly judge the quality through "touch and feel" experiences.
Essays in Constructive Mathematics
This book aims to promote constructive mathematics, not by defining it or formalizing it, but by practicing it, by basing all definitions and proofs on finite algorithms. The topics covered derive from classic works of nineteenth century mathematics---among them Galois' theory of algebraic equations, Gauss's theory of binary quadratic forms and Abel's theorem about integrals of rational differentials on algebraic curves. It is not surprising that the first two topics can be treated constructively---although the constructive treatments shed a surprising amount of light on them---but the last topic, involving integrals and differentials as it does, might seem to call for infinite processes. In this case too, however, finite algorithms suffice to define the genus of an algebraic curve, to prove that birationally equivalent curves have the same genus, and to prove the Riemann-Roch theorem. The main algorithm in this case is Newton's polygon, which is given a full treatment. Other topics covered include the fundamental theorem of algebra, the factorization of polynomials over an algebraic number field, and the spectral theorem for symmetric matrices.
Essays and Surveys in Global Optimization
Global optimization aims at solving the most general problems of deterministic mathematical programming: to find the global optimum of a nonlinear, nonconvex, multivariate function of continuous and/or integer variables subject to constraints which may be themselves nonlinear and nonconvex. In addition, once the solutions are found, proof of its optimality is also expected from this methodology. Therefore, with these difficulties in mind, global optimization is becoming an increasingly powerful and important methodology. Essays and Surveys in Global Optimization is the most recent examination of its mathematical capability, power, and wide ranging solutions to many fields in the applied sciences.
ESR Spectroscopy in Membrane Biophysics
Membrane proteins offer the greatest challenge in structural biology, and there is an urgent need to develop and apply new biophysical methodologies that are able to generate detailed structural information.

Esercizi di fisica : Meccanica e termodinamica = Physics exercises : Mechanics and thermodynamics
La risoluzione di esercizi rappresenta uno strumento indispensabile per raggiungere una comprensione sicura e approfondita dei concetti di Fisica appresi dai corsi e dai testi di teoria. Frutto di una lunga esperienza didattica dei due autori nell'insegnamento universitario della meccanica e della termodinamica, questa raccolta contiene 188 esercizi, di cui 91 completamente risolti ed accompagnati da un ampio corredo di figure. Il peimo capitolo presenta un'introduzione ai sistemi di unità di misura, al calcolo dimensionale, all'uso corretto delle cifre significative e degli arrotondamenti, ai grafici. Gli altri capitoli contengono gli esercizi, suddivisi per argomento e preceduti da una serie di paragrafi riassuntivi dei concetti fondamentali. Criterio ispiratore di questo lavoro è l'adozione di una metodologia per la soluzione degli esercizi basata sempre sull'analisi accurata dei dati a disposizione e sul riferimento ai principi e alle leggi della Fisica, mai alla sola intuizione.
