The aim of this work is to analyze the chemical and physical properties of balsamic vinegar, in order to improve the chemical information about this product, useful for its authentication and quality evaluation. Using three balsamic vinegars purchased in local markets as samples, this study investigated the labeling and the physicochemical properties of commercial concentrated balsamic vinegar in order to understand their production method and quality. Two of the samples were balsamic vinegars from Modena (BVM) and the third was a balsamic vinegar from Kalamata (BVK). According to the labels, all the balsamic vinegars samples were made of grape must and had an acidity of 6%. The appearance of the samples of vinegar differed significantly, but the acidity from the label was the same for all. Since people are paying much more attention to health, the number of concentrated vinegar products is expected to increase in the future. Thus, appropriate rules and physicochemical properties are required to regulate vinegar production and quality.

The article discusses the future of mobility in the light of energy resources. Fossil fuel will not be available for a long time - not to mention its growing environmental and political conflicts. In analysing the potential of biofuel it is argued that the high demands of modern mobility can hardly be fulfilled in the future. Furthermore, the change into using biofuel will probably lead to increasing conflicts between the fuel market and the food market, as well as to conflicts with regional agricultural networks in the third world. Petrol imperialism might be replaced by bio imperialism. Therefore, mobility on a solar base pursues a double strategy of raising efficiency on the one hand and strongly reducing mobility itself on the other.

En este artículo examinaremos algunas de las principales estrategias discursivas empleadas en dos artículos publicados por U. Eco en L’Espresso, una revista semanal muy conocida en Italia de carácter político, social, cultural y económico, en el marco de una página personal titulada “La Bustina di Minerva”, es decir, “El Sobrecito de Minerva”. El título es una referencia a la comunicación breve, a las observaciones de cualquier tipo, pero igualmente, de forma simultánea. Los sobrecitos reflexionan sobre el mundo contemporáneo, la sociedad italiana, los medios de comunicación de masas; tratan de la actualidad y la relacionan con la historia y la filosofía, con Internet y el futuro del Tercer Milenio, y nos proponen los pensamientos de U. Eco con más viveza que una conferencia o un tratado.La ironía, la sátira y la parodia son las bases argumentativas de muchos “Sobrecitos”. Generalmente, el humor transmite dos sentidos a la vez. Detrás de una serie de textos tan variados temáticamente aparece a menudo una misma estructura binaria, un cuerpo dual. Con frecuencia, un mismo artículo obedece a una doble orientación tematica, ya que suelen mezclar dos motivos que pertenecen a áreas diferentes, alternando simultáneamente dos sujetos. A esta doble orientación temática del “Sobrecito” corresponde la doble orientación semántica de la palabra irónica que, junto con la parodia es un discurso dialógico o bi-direccional en el que se mezclan dos voces.In this article some of the main discursive strategies used in two articles published by U. Eco are examined. These articles have been published in L'Espresso, a weekly review very widespread in Italy, of political, social, cultural and economic character, within the framework of a column titled “La Bustina di Minerva”, that is to say, “The little bag/envelope of Minerva”. This title refers to a brief communication, to observations of any type, but also, immediate. The “bustine” reflects on the contemporary world, the Italian society, the mass media; they deal with present time and relate it to history and philosophy, Internet and the future of the Third Millennium, and they propose us Eco’s thoughts with more vividness than a conference or an essay.Irony, satire and parody are the argumentative bases of many “bustine”. Generally, humour transmits two senses simultaneously. Behind a series of texts so thematically varied there is often a same binary structure, a dual body. Frequently, a same article obeys to a double thematic direction, since usually they mix two arguments that belong to different areas, alternating two subjects simultaneously. To this double thematic direction of the “bustina” corresponds the double semantic direction of the ironic word that, along with parody, is a dialogic or bidirectional speech in which two voices are mixed.

Background: Solubility and dissolution profile are the major factors which directly affect the biological activity of a drug and these factors are governed by the physicochemical properties of the drug. Crystal engineering is a newer and promising approach to improve physicochemical characteristics of a drug without any change in its pharmacological action through a selection of a wide range of easily available crystal formers. Objective: The goal of this review is to summarize the importance of crystal engineering in improving the physicochemical properties of a drug, methods of design, development, and applications of cocrystals along with future trends in research of pharmaceutical co-crystals. Co-crystallization can also be carried out for the molecules which lack ionizable functional groups, unlike salts which require ionizable groups. Conclusion: Co-crystals is an interesting and promising research area amongst pharmaceutical scientists to fine-tune the physicochemical properties of drug materials. Co-crystallization can be a tool to increase the lifecycle of an older drug molecule. Crystal engineering carries the potential of being an advantageous technique than any other approach used in the pharmaceutical industry. Crystal engineering offers a plethora of biopharmaceutical and physicochemical enhancements to a drug molecule without the need of any pharmacological change in the drug.

AbstractCOVID-19 is the third spread of animal coronavirus over the past two decades, resulting in a major epidemic in humans after SARS and MERS. COVID-19 is responsible of the biggest biological earthquake in the world. In the global fight against COVID-19 some serious mistakes have been done like, the countries’ misguided attempts to protect their economies, lack of international co-operation. These mistakes that the people had done in previous deadly outbreaks. The result has been a greater economic devastation and the collapse of national and international trust for all. In this constantly changing environment, if we have a better understanding of the host-virus interactions than we can be more prepared to the future deadly outbreaks. When encountered with a disease which the causative is unknown, the reaction time and the precautions that should be taken matters a great deal. In this review we aimed to reveal the molecular footprints of COVID-19 scientifically and to get an understanding of the pandemia. This review might be a highlight to the possible outbreaks.

This essay is a comment on the research program launched by Frank Adloff and Sighard Neckel. My comment is specifically focused on their research agenda as outlined in their trend-setting article, ‘Futures of sustainability as modernization, transformation, and control: A conceptual framework’. The comment is also addressed more generally to the research program of the Humanities Centre for Advanced Studies ‘Futures of Sustainability’. I raise three issues: the first relates to the very idea of the future; the second concerns the notion of social imaginaries and the third question is focused on the idea of social transformation.

Early in 1963 much of the land occupied by the Roman building at Fishbourne was purchased by Mr. I. D. Margary, M.A., F.S.A., and was given to the Sussex Archaeological Trust. The Fishbourne Committee of the trust was set up to administer the future of the site. The third season's excavation, carried out at the desire of this committee, was again organized by the Chichester Civic Society.1 About fifty volunteers a day were employed from 24th July to 3rd September. Excavation concentrated upon three main areas; the orchard south of the east wing excavated in 1962, the west end of the north wing, and the west wing. In addition, trial trenches were dug at the north-east and north-west extremities of the building and in the area to the north of the north wing. The work of supervision was carried out by Miss F. Pierce, M.A., Mr. B. Morley, Mr. A. B. Norton, B.A., and Mr. J. P. Wild, B.A. Photography was organized by Mr. D. B. Baker and Mrs. F. A. Cunliffe took charge of the pottery and finds.
