This leatherbound volume lists books donated to the Harvard College Library by Jasper Mauduit, who served as an agent in London on behalf of the Province of the Massachusetts Bay. Entries are arranged alphabetically and by format; i.e. the first page lists all folios whose author, title, or keyword begin with "A," the next page lists all quartos beginning with "A," and the following page lists all "octavo &ca" volumes beginning with "A." The volume continues in a similar manner for each letter of the alphabet. Following a devastating fire in 1764 which destroyed most of the books in the Harvard College Library, Mauduit donated books, as well as money for the purchase of books, to the College. He also acted as an agent of the Society for Propagating the Gospel in New England and Parts Adjacent, using the £300 they donated for the rebuilding of the College library to select and purchase a large number of books. It is not known if the books listed in this catalog are those donated by Mauduit himself, or if they are the donations he purchased on behalf of the Society. The creator of this volume is unknown; although all entries are made in the same hand, the identity of the writer has not been determined. The label attached to the front cover, which refers to the Lime Street address of Mauduit's business in London, suggests that the list might have been prepared by Mauduit himself.

As the difficulties Gazprom has faced in recent years on the European market have multiplied1, so more and more symptoms have appeared which may suggest that the company’s dominant position is deteriorating. The decision made by the Russian government in June 2011 to double the tax Gazprom has to pay on the extraction of gas, which was later approved by parliament, was the first time in many years when the company’s fiscal privileges were withdrawn. The process of Gazprom’s assets being taken over by private companies and business partners from within Vladimir Putin’s closest circle is underway. More and more frequently attempts are being made to challenge the company’s monopoly in areas of key importance for the functioning of the entire gas sector, such as Gazprom’s exclusive right to dispose of the Russian gas transportation system and its exports monopoly. Competition from independent gas producers on the domestic market is growing, and Gazprom is gradually being pushed out of some of that market’s most profitable segments (industrial clients). The emerging tendencies in the Russian gas sector derive from a number of factors – from the situation on the European gas market, through difficulties hampering the development of the sector in Russia itself, to the private interests of the current ruling class and its business partners. The plans for a structural reform of the monopoly (including isolating gas transportation system from Gazprom), presented since 2000 by the Ministry for Economic Development and since 2003 by the Russian Association of Industrialists and Entrepreneurs (RSPP), suggest a direction for the changes necessary to stimulate the sector’s development and improve the efficiency of Gazprom itself. However, the monopolist’s current business model gives the government full control over this strategic enterprise, which is a core of Putin’s concept for developing Russia as a global energy power. Despite Putin’s recent statement that he “does not rule out privatising Gazprom in the future” (made at a meeting with political scientists in Moscow on 6 February this year), any structural reform of Gazprom (and consequently, a weakening of the state’s control over it) seems unlikely in the foreseeable future. Still, the developments on the domestic market – growing pressure from other gas companies (oil corporations and independent producers) and changes on the European market2 – may result in the weakening of Gazprom’s monopoly privileges and a gradual deterioration of its special status within Russia.

- Mobile telecommunications markets are an important part of the European Commission’s strategy for the completion of the European Union Digital Single. The use of mobile telecommunications – particularly mobile data access – is growing and becoming an increasingly important input for the economy. - The EU currently does not have a unified mobile telecommunications market. The EU compares favourably to the United States in terms of prices and connection speed, but lags behind in terms of coverage of high-speed 4G wireless connections. -Europe’s long-term goal should be to make data access easier by increasing highspeed wireless coverage while keeping prices down for users. An increase in cross-border competition could help to achieve that goal. - The Commission has two important levers to help stimulate cross-border supply:(a) ensuring competition in intra-country mobile markets in order to provide an incentive for operators to expand into other jurisdictions, and (b) reducing mobile operators’ costs of expansion into multiple EU countries. The further development of policies on international roaming and radio spectrum management will be central to this effort.

This paper describes the first 4-year period (2012–2015) of implementation of the Portuguese National Programme for the Promotion of Healthy Eating (PNPAS). PNPAS was approved in 2012 and emerged as a preventive programme for noncommunicable diseases, aiming to improve the nutritional status of the population; it represents the first national strategy in Portugal for the promotion of healthy eating. To accomplish its mission, and taking into account its overall principles, PNPAS has five main goals: (i) to increase knowledge about the food intake of the Portuguese population and about its determinants and consequences; (ii) to modify the availability of certain foods (high in sugar, salt and fat), in schools, workplaces and public spaces; (iii) to inform and empower the population for the purchase, preparation and storage of healthy food, especially the most vulnerable groups; (iv) to identify and promote crosssectoral actions that encourage the consumption of foods of good nutritional quality in an articulate and integrated way with other sectors, namely agriculture, sport, environment, education, social security and local authorities; and (v) to improve the qualifications and conduct of the different professionals who, owing to their roles, may influence nutritional knowledge, attitudes and behaviours. The design of PNPAS followed the latest strategic lines suggested by WHO and the European Commission, proposing a crosssectoral mix of interventions to ensure physical and economic access to healthy eating by creating healthy environments and empowering individuals and communities. Several actions were implemented at different levels during the first 4-year period of implementation of PNPAS; two were especially relevant. The first concerned the empowerment of citizens regarding healthy eating, where the most important aspect was introduction of a digital strategy through development of a website and a blog dedicated to healthy eating. The second concerned the development of documents for health care and other professionals, including several guidelines in new areas, such as anthropometric measures and intervention in preobesity. Process and output indicators were defined to monitor and evaluate the programme. Among those considered as output indicators were the evaluation of childhood obesity, salt consumption and intake of breakfast by school-aged children.

Se estudió la influencia de las variaciones estacionales del nivel de agua sobre la reproducción y el crecimiento de Potamorhina altamazonica en el río Ucayali durante los años 2008-2012. Se observó que, la reproducción es de carácter estacional, que, tiene sincronía con el periodo de creciente (enero-marzo) alcanzado el ápice en febrero. Se estimó que las hembras alcanzan la talla media de primera madurez a los 17,8 cm y los machos a los 18,4 cm (Lt), en ambos casos a la edad teórica de un año. La mayor proporción de hembras respecto a los machos se observó en el periodo de transición a creciente, y viceversa en la creciente; mientras que el análisis anual mostró dominancia de hembras en los años 2008 y 2012. El análisis de la estructura de tallas mostró que el stock explotado estuvo compuesto por peces cuyas tallas oscilaron de 12,0 a 31,0 cm Lt y no se observaron fuertes fluctuaciones de la talla media anual. La ecuación de crecimiento de von Bertalanffy definida por Lt = 33,55*(1-e(-0,65(t-0,26)) permite estimar que la especie es de rápido crecimiento y que podría vivir en teoría 3,5 años. Los peces mostraron mejor condición o robustez en los periodos de transición a creciente y creciente, dado a que en estos, se inundan vastas áreas de bosques de llanura convirtiéndose en hábitats óptimos que favorecen la reproducción en los peces adultos y el crecimiento en los reclutas.

Termites are the most important soil ecosystem engineers of semi-arid and arid habitats. They enhance decomposition processes as well as the subsequent mineralisation of nutrients by bacteria and fungi. Through their construction of galleries, nests and mounds, they promote soil turnover and influence the distribution of nutrients and also alter texture and hydrological properties of soils, thereby affecting the heterogeneity of their ecosystem. The main aim of the present thesis was to define the impact of termites on ecosys-tem functioning in a semi-arid ecosystem. In a baseline study, I assessed the diversity of termite taxa in relation to the amount of precipitation, the vegetation patterns and the land use systems at several sites in Namibia. Subsequently, I focussed on a species that is highly abundant in many African savannas, the fungus growing and mound building species Macro-termes michaelseni (Sjöstedt, 1914). I asked how this species influences the spatial hetero-geneity of soil and vegetation patterns. From repeated samplings at 13 sites in Namibia, I obtained 17 termite taxa of 15 genera. While the type of land use seems to have a minor effect on the termite fauna, the mean annual precipitation explained 96% and the Simpson index of vascular plant diversity 81% of the variation in taxa diversity. The number of termite taxa increased with both of these explanation variables. In contrast to former studies on Macrotermes mounds in several regions of Africa that I reviewed, soil analyses from M. michaelseni mounds in the central Namibian savanna revealed that they contain much higher nitrogen contents when compared to their parent material. Further analyses revealed that nitrate forms a major component of the nitrogen content in termite mounds. As nitrate solves easily in water, evaporation processes are most probably responsible for the transport of solved nitrates to the mound surface and their accumulation there. The analysed mounds in central Namibia contained higher sand propor-tions compared to the mounds of the former studies. Through the higher percentage of coarse and middle sized pores, water moves more easily in sandy soils compared to more clayey soils. In consequence, evaporation-driven nitrate accumulation can occur in the studied mounds at high rates. ff...

Gelatinisation of starch in mixtures of sugars. II. Application of differential scanning calorimetry
Resumo:
Differential scanning calorimetry was used to investigate the effect of mixtures of glucose and fructose, and five types of honeys on starch gelatinisation. At a 1:1 starch:water ratio, glucose generally increased the enthalpy (DeltaH(gel)) and temperatures (T-onset, T-peak and T-end) of gelatinisation more than fructose. Upon mixing, DeltaH(gel) of the low-temperature endotherm decreased in comparison to the sole sugars, but was fairly constant (7.7 +/- 0.33 J/g dry starch). DeltaH(gel) of the high-temperature endotherm increased with the fructose content. For both endotherms, the gelatinisation temperatures were unchanged (CV less than or equal to 3%) for the mixtures. With the honeys (moisture, 14.9-18.0%; fructose, 37.2-44.0%; glucose, 28.3-31.9%) added at 1.1-4.4 g per g dry starch, the enthalpy and temperatures of gelatinisation did not vary significantly (CV less than or equal to 6%). Typical thermograms are presented, and the results are interpreted in the light of the various proposed mechanisms for starch gelatinisation in sugar-water systems, total sugar content and possible sugar-sugar interactions. The thermograms were broader in the presence of the sugars and honeys, and a biphasic character was consistently exhibited. The application of an exponential equation to the gelatinisation temperatures of the starch-honey mixtures revealed an opposing influence of fructose and glucose during gelatinisation. The mechanism of starch gelatinisation may be better understood if techniques could be perfected to quantify breakage and formation of hydrogen bonds in the starch granules, and suggested techniques are discussed.

Half of the members of the nuclear receptors superfamily are so-called orphan receptors because the identity of their ligand, if any, is unknown. Because of their important biological roles, the study of orphan receptors has attracted much attention recently and has resulted in rapid advances that have helped in the discovery of novel signaling pathways. In this review we present the main features of orphan receptors, discuss the structure of their ligand-binding domains and their biological functions. The paradoxical existence of a pharmacology of orphan receptors, a rapidly growing and innovative field, is highlighted.
