Semplice come i francobolli (Italian Edition)

Migliavacca explained that many of the early traveler's guides published in Italy between the s and s were almost invariably written by authors who had close ties with the postal service. The first postal guide Le poste necessarie a' corrieri was published in Venice and saw three editions between and in conjunction with the Catholic Church Council of Trento Tridentine Council.

The well-known postal historian went on to say that during the late s, throughout the s, and beyond, the word "post" did not have the same meaning we give to it nowadays.

A post was a place at some junction, in town or in the countryside, where it was possible to hire or change a horse, and in most cases get a meal and some rest. This measurement was important because it affected the cost and fees for hiring horses, postilions and coaches. It must be noted that the posts, or postal inns, also handled mail. The earliest surviving edition is that published by Ioanne Battista Bozola and printed in Brescia in by Damiano Turlino. The city also drew huge numbers of businessmen, tourists, and other visitors. It is no surprise that a second and a third edition were published in a rather short time.

A lucrative industry of postal guides was born from this little acorn. In due course these booklets librettos helped the traveler plan his journey and see which posts were on his route. That the book in its second edition was already targeting travelers and businessmen becomes apparent from the subtitle - "And Also with the Addition of the names of all the Fairs held all over the world".

In fact, of the edition there does not seem to have survived a single copy, while of the edition only the Marciana Library in Venice and the Ambrosiana Library in Milan are privileged to have a copy. The many editions of the postal guides suggest that these publications were readily available at retail outlets that have not yet been identified but must have included booksellers, inns, and postal stations.

Migliavacca is not new to publishing reprints of important books. In fact, in he published the reprint of another famous postal guide written in the early s by the Deputy Postmaster General of Milan, Ottavio Codogno. Migliavacca and copies of it can now be found in some of the most important libraries worldwide. It is also a highly desirable collectible for bibliophiles and specialists.

Biotechnology experiments are especially sensitive to biologically active species, such as endotoxins, RNase and DNase, transition metals and dissolved organic compounds. Trace high-performance liquid chromatography HPLC requires ultra-pure water, with very low organic contamination, principally as an eluent component. Naturally, trace analytical work requires water that is free from the components to be measured but also from any potential interferants. Purified water used in laboratories is usually produced in-situ from local potable water which has been produced by the treatment of natural water sources.

For potable water, the overall requirement is to produce drinking water that conforms to regulations and has acceptable clarity, taste and odor. Natural water is taken from upland sources, such as reservoirs, from rivers or from underground aquifers and potable water is produced by a series of steps which vary with the water source, local and national regulations and the choice of technologies. One approach is outlined here. After passing through a series of screens to remove debris, the water is mixed with ozone in contact tanks, to oxidise pesticides and herbicides and kill bacteria and algae.

Excess ozone is destroyed. Water is then clarified to remove suspended solids, which are collected as a sludge cake. A flocculent such as poly-aluminium chloride may be added to help this process. This traps the solids and organic matter. Finally chlorine is added to kill remaining bacteria. A small residual of chlorine is left to maintain low bacterial levels. An extra ultrafiltration stage is increasingly being used to remove cryptosporidium.

Impurities in potable water The unique ability of water to dissolve, to some extent, virtually every chemical compound and support practically every form of life means that potable water supplies contain many substances in solution or suspension. Unlike other raw materials, potable water varies significantly in purity both from one geographical region to another and from season to season. Water derived from an upland surface source, for instance, usually has a low content of dissolved salts and is relatively soft, but has a high concentration of organic contamination, much of it colloidal.

By contrast, water from an underground source generally has a high level of salts and hardness but a low organic content. River sources are intermediate in quality but also often contain products from industrial, agricultural and domestic activities. Seasonal variations in water quality are most apparent in surface waters. During the autumn and winter months, dead leaves and decaying plants release large quantities of organic matter into streams, lakes and reservoirs.

As a result, organic contamination in surface waters reaches a peak in winter, and falls to a minimum in summer. Ground waters are much less affected by the seasons. The quality and characteristics of the potable water supply have an important bearing on the purification regime required to produce purified water. Gli esperimenti di biotecnologia sono particolarmente sensibili alle specie biologicamente attive, come le endotossine, la RNnasi e la DNnasi, i metalli di transizione ed i composti organici disciolti. La cromatografia liquida ad alto rendimento HPLC richiede acqua ultrapura, con contaminazione organica bassissima, principalmente come componente di un eluente.

Naturalmente, il lavoro analitico di traccia richiede acqua esente dai componenti da misurare ma anche da eventuali interferenti potenziali. In questa sede, si descrive a grandi linee un approccio. Tale operazione intrappola i solidi e la materia organica. Infine, si aggiunge del cloro per uccidere i batteri restanti. Di contro, l'acqua proveniente da una sorgente sotterranea in genere presenta un alto livello di sali e durezza ma un basso contenuto organico.

Di conseguenza, la contaminazione organica nelle acque superficiali raggiunge un picco in inverno e scende al livello minimo in estate. Le acque di pozzo sono molto meno influenzate dalle stagioni.

Crude oil and natural gas are naturally occurring hydrocarbons found in many areas of the world in varying quantities and compositions. In refineries, they are transformed into different products as: In order to manufacture these products, these raw materials are processed in a number of different refining facilities.

The combination of these processing units to convert crude oil and natural gas into products, including its supporting units and facilities, is called a refinery. The market demand for the type of products, the available crude quality and certain requirements set by authorities influence the size, configuration and complexity of a refinery. As these factors vary from location to location no two refineries are identical. Refineries discharge waste water which originates from: These waters have been in contact with the process fluids, and apart from oil, will also have taken up hydrogen sulphide H2S , ammonia NH3 and phenols.

The more severe the conversion processes, the more H2S and NH3 are taken up by the process water. The process water is treated in several, well-known steps before discharge to the environment. General overview of the refinery processes Crude oil and natural gas are mixtures of many different hydrocarbons and small amounts of impurities. The composition of those raw materials can vary significantly depending on its source.

Petroleum refineries are complex plants, where the combination and sequence of processes is usually very specific to the characteristics of the raw materials crude oil and the products to be produced. In a refinery, portions of the outputs from some processes are fed back into the same process, fed to new processes, fed back to a previous process or blended with other outputs to form finished products. One example of that can be seen in Figure 2. The production of a large number of fuels is by far the most important function of refineries and will generally determine the overall configuration and operation.

Nevertheless some refineries can produce valuable non-fuel products such as feedstocks for the chemical and petrochemical industries. Nelle raffinerie, essi sono trasformati in diversi prodotti, quali: Ai fini della fabbricazione di tali prodotti, queste materie prime sono lavorate in un determinato numero di varie strutture di raffinazione. Le raffinerie scaricano acqua reflue derivanti da: Tali tipi di acqua sono state a contatto con liquidi di lavorazione e, a parte il petrolio, hanno anche assorbito solfuro di idrogeno H2S , ammoniaca NH3 e fenoli.

In una raffineria, parti delle produzioni provenienti da alcuni processi sono alimentate nuovamente nello stesso processo, alimentate su nuovi processi, alimentate nuovamente a un processo precedente o miscelate con altre produzioni per formare prodotti finiti. Ciononostante, alcune raffinerie possono produrre prodotti non combustibili preziosi, come i feedstock per le industrie chimiche e petrolchimiche.
