Bioclimatic characterization of outdoor and confined systems for pregnant sows

Pregnant sows confinement systems were created in order to maximize the productivity, however there are problems concerning the animal welfare. The aim of this research was to evaluate pregnant sows in outdoors and in confinement systems in relation to the thermal environment and physiological animal responses. The experiment was conducted in a commercial farm in Monte Mor city, Sao Paulo, Brazil. The physiological evaluation was performed by recording physiological variables, such as respiratory frequency and skin temperature. Furthermore, variables like dry bulb temperature, wet bulb temperature, and black globe temperature were also evaluated to characterize the ambient by means of enthalpy and black globe humidity index. In each treatment six animals were evaluated. The experimental design was completely randomized in a split-plot version whose averages were compared by the Tukey test. The findings of the experiment revealed higher values for all the bioclimatic variables in the confined treatment. Hence, the outdoor system provided better thermal conditioning for pigs, resulting in a lower heat stress.

An Extreme Case of Plant-Insect Codiversification: Figs and Fig-Pollinating Wasps

It is thought that speciation in phytophagous insects is often due to colonization of novel host plants, because radiations of plant and insect lineages are typically asynchronous. Recent phylogenetic comparisons have supported this model of diversification for both insect herbivores and specialized pollinators. An exceptional case where contemporaneous plant-insect diversification might be expected is the obligate mutualism between fig trees (Ficus species, Moraceae) and their pollinating wasps (Agaonidae, Hymenoptera). The ubiquity and ecological significance of this mutualism in tropical and subtropical ecosystems has long intrigued biologists, but the systematic challenge posed by >750 interacting species pairs has hindered progress toward understanding its evolutionary history. In particular, taxon sampling and analytical tools have been insufficient for large-scale cophylogenetic analyses. Here, we sampled nearly 200 interacting pairs of fig and wasp species from across the globe. Two supermatrices were assembled: on an average, wasps had sequences from 77% of 6 genes (5.6 kb), figs had sequences from 60% of 5 genes (5.5 kb), and overall 850 new DNA sequences were generated for this study. We also developed a new analytical tool, Jane 2, for event-based phylogenetic reconciliation analysis of very large data sets. Separate Bayesian phylogenetic analyses for figs and fig wasps under relaxed molecular clock assumptions indicate Cretaceous diversification of crown groups and contemporaneous divergence for nearly half of all fig and pollinator lineages. Event-based cophylogenetic analyses further support the codiversification hypothesis. Biogeographic analyses indicate that the present-day distribution of fig and pollinator lineages is consistent with a Eurasian origin and subsequent dispersal, rather than with Gondwanan vicariance. Overall, our findings indicate that the fig-pollinator mutualism represents an extreme case among plant-insect interactions of coordinated dispersal and long-term codiversification.

Impatto ambientale dei rifiuti e degli sprechi agroalimentari in Europa e in Italia

Nonostante il fatto che una gran parte del mondo viva ancora oggi a livelli di sussistenza, i dati in nostro possesso ci indicano che le attività umane stanno esaurendo le risorse ambientali del pianeta. La causa di questo eccessivo sfruttamento delle risorse è da ricercare nei pattern non sostenibili di produzione e consumo dei paesi sviluppati. La preoccupazione per le conseguenze sull'ambiente e la lotta al cambiamento climatico hanno posto le politiche ambientali al centro dell'attenzione internazionale. Il Protocollo di Kyoto e la Commissione Europea hanno stabilito degli obiettivi di riduzione delle emissioni di gas serra, rispettivamente del 12% entro il 2012 e del 20% entro il 2020. All'interno del Protocollo di Kyoto l'obiettivo per l'Italia è ridurre del 6,5% le emissioni di gas serra nazionali rispetto al 1990. Le politiche mirate alla riduzione delle emissioni di gas serra hanno in genere come obiettivo gli impianti energetici e i trasporti. Poca attenzione viene data alla filiera agroalimentare pur sapendo che l'agricoltura ha un forte impatto sull'ambiente e recenti studi stimano che circa il 50% del cibo prodotto viene perso o buttato via dalla produzione al consumo. Alla luce di questi dati, il mio lavoro di tesi ha avuto come obiettivo quello di quantificare i rifiuti e gli sprechi agroalimentari in Europa e in Italia e stimare l'impatto ambientale associato. I dati raccolti in questa tesi mettono in evidenza l'importanza di migliorare l'efficienza della filiera agroalimentare per ridurre l'impatto ambientale nazionale e rispettare gli accordi internazionali sulla lotta ai cambiamenti climatici.

"Per una mappatura della Russia contemporanea". Aleksej Ivanov, il geografo si è bevuto il globo. Proposta di traduzione editoriale.

The purpose of this work is to introduce to the Italian audience one of the best known works written by the Russian novelist Aleksej Ivanov. The title of the book we refer to is Geograf glubus propil, [The geography drank his globe away]. The novel features peculiarities and themes that can be interesting also for non-Russian readers, being also an example of how Russian contemporary literature has evolved through the years. Nevertheless, it has already been translated in French and Serbian. In last years, the author has become increasingly famous in Russia: he has won many prices and has published a large number of books, many of which were awarded with different literature prizes. Moreover, a film based on the plot of the novel analyzed has been released in 2013, carrying the same name of the book. The film received positive feedback from both cinema critics and mass audience. The following work has been divided into two parts: an introductory part where the author and his book are presented, together with the main character and his peculiarities. It is then explained the context in which the book was created, the purpose of the author and how the book was perceived by readers. In addition to that, I listed some of the problems I had to face while translating , and the solutions I found in order to solve them. The second part is fully dedicated to the translation itself.

Videogame localization. A case study: Final Fantasy XII

Globalization has influenced all economic sectors and the demand for translation services has increased like never before. The videogame industry has become a worldwide phenomenon worth billions. Many people around the globe, male and female, children and adults alike, choose this leisure activity and enjoy it like reading or watching a film. It is a global phenomenon capable of producing as much revenue and anticipation as the film industry. Most games are developed in Japanese or English and the new global market requires this product to be translated into many other languages. The scenario has brought about a new field of specialization in translation studies, commonly known as videogame localization. The emergence of this new field calls not only for a review of translation studies, but also a shift in the role that some translators and translated products are expected to play within a globalized world. The aim of this dissertation is to provide an overview of videogame localization and its challenges under the guidance of a professional translator such as Alexander O. Smith, who agreed to provide counsel through several Skype interviews. This provided a first-hand insight into how translation decisions are carried out by game translators. Alexander O. Smith was a former translator for Square Enix, one of the biggest Japanese videogame developer, publisher and distribution company in the market. He now works as an independent translator and in 2003 he founded the localization agency called Kajiya Productions with his friend and fellow translator Joseph Reeder. Together with Alexander O. Smith, the twelfth installment of the Final Fantasy series by Square Enix has been chosen as a very good example of the issues and challenges brought on by videogame localization. The game which revealed itself to be one of the most fun, challenging and rewarding professional experiences of Alexander O. Smith.

Estimation of the risks of thermal stress due to the microclimate for manual fruit and vegetable harvesters in central Italy

Agricultural workers are exposed to various risks, including chemical agents, noise, and many other factors. One of the most characteristic and least known risk factors is constituted by the microclimatic conditions in the different phases of work (in field, in greenhouse, etc). A typical condition is thermal stress due to high temperatures during harvesting operations in open fields or in greenhouses. In Italy, harvesting is carried out for many hours during the day, mainly in the summer, with temperatures often higher than 30 degrees C. According to ISO 7243, these conditions can be considered dangerous for workers' health. The aim of this study is to assess the risks of exposure to microclimatic conditions (heat) for fruit and vegetable harvesters in central Italy by applying methods established by international standards. In order to estimate the risk for workers, the air temperature, radiative temperature, and air speed were measured using instruments in conformity with ISO 7726. Thermodynamic parameters and two more subjective parameters, clothing and the metabolic heat production rate related to the worker's physical activity, were used to calculate the predicted heat strain (PHS) for the exposed workers in conformity with ISO 7933. Environmental and subjective parameters were also measured for greenhouse workers, according to ISO 7243, in order to calculate the wet-bulb globe temperature (WBGT). The results show a slight risk for workers during manual harvesting in the field. On the other hand, the data collected in the greenhouses show that the risk for workers must not be underestimated. The results of the study show that, for manual harvesting work in climates similar to central Italy, it is essential to provide plenty of drinking water and acclimatization for the workers in order to reduce health risks. Moreover, the study emphasizes that the possible health risks for greenhouse workers increase from the month of April through July.

Civic Discipline: Geography in America, 1860-1890

Civic Discipline argues that the story of the origins of American geography is a distinctly "New York story." Wealthy businessmen began America's first geographical society - the American Geographical Society - in 1851, inspired by what geographical knowledge of the globe could offer an expanding American commercial Empire at home and abroad. AGS meetings were spectacularly popular among the public and press. At them, geography was cast as a science in the service of the public and civic good. Meanwhile though, AGS men's spatial and financial "missions" became closely linked. They helped improve derelict spaces in New York City and weighed in on controversial scientific questions of the day in the Arctic, yet the geographical knowledge they advanced - such as in the American West and in Central Africa - also created enormous personal wealth. Civic Discipline shows that it was not just that historical events shaped geography, but rather, that geography shaped historical events.

INVESTIGATION OF INTRAOCULAR PRESSURE AS A PREDICTOR OF TRAUMATIC EYE INJURIES

Eye injuries are a large societal problem in both the military and civilian sectors. Eye injury rates are increasing in recent military conflicts, and there are over 1.9 million eye injuries in the United States civilian sector annually. In order to develop a better understanding of eye injury risk, several previous studies have developed eye injury criteria based on projectile characteristics. While these injury criteria have been used to estimate eye injury potential of impact scenarios, they require that the mass, size and velocity of the projectile are known. It is desirable to develop a method to assess the severity of an eye impact in environments where it would be difficult or impossible to determine these projectile characteristics. The current study presents a measurement technique for monitoring intraocular pressure of the eye under impactloading. Through experimental tests with a custom pressure chamber, a subminiature pressure transducer was validated to be thermally stable and suitable for testing in an impact environment.Once validated, the transducer was utilized intraocularly, inserted through the optic nerve, to measure the pressure of the eye during blunt-projectile impacts. A total of 150 impact tests were performed using projectiles ranging from 3.2 mm to 17.5 mm in diameter. Investigation of the relationship between projectile energy and intraocular pressure lead to the identification of at least two distinct trends. Intraocular pressure and normalized energy measurements indicated a different response for penetrating-type globe rupture injuries with smaller diameter (d < 1 cm)projectiles, and blunt-type globe rupture injuries with larger diameter (d > 1 cm) projectiles. Furthermore, regression analysis indicates that relationships exist between intraocular pressureand projectile energy that may allow quantification of eye injury risk based on pressure data, and also that intraocular pressure measurements of impact may lead to a better understanding of thetransition between penetrating and blunt globe rupture injury mechanisms.

An Analysis Of U.S.- Economic Policy Toward Chile During The Cold War

This examination of U.S. economic policy directed toward Chile centered on the political and economic changes that occurred within Chile between 1960 and 1988. During this time, U.S. economic policy directed toward Chile was crafted by members of the American government uneasy with Cold War concerns with the most important of which being the spread of Communism throughout the globe. By viewing U.S. policy toward Chile through this Cold War lens, this thesis explores the different ways in which economic policy was used to advance the political and economic goals within not only Chile, but also Latin America as a whole. The Cold Warriors that crafted and enacted these economic policies were motivated by a variety of factors, and influenced by events outside of their control. From President John F. Kennedy to Ronald Reagan, American policymakers utilized economic policy as a means to achieve regional goals. This project sheds light on an understudied section of U.S. foreign policy history by exploring the way that economic policy helped achieve Cold War objectives in the Southern Cone.

American Challenges

In the autumn of 2008, with the United States facing myriad problems both foreign and domestic and entering the final stage of a historic election, The Boston Globe asked Mosakowski Institute Director Jim Gomes to write a series of op-ed pieces about critical issues on the nation’s agenda. The result is the six columns collected here in American Challenges. “When I wrote these pieces,” said Gomes, “the country had entered a period of great uncertainty. So much of what had been taken as a given in the last half of the 20th century, from broadly shared prosperity to the health of our political system to America’s place of leadership in the world, was being called into question.” These columns appeared in the Globe between October 27 and December 1, 2008. Together, they touch upon many enduring questions about the public enterprise in America.

Restoration of forest wetlands: Case studies in Michigan and Finland

Forested wetlands throughout the world are valuable habitats; especially in relatively species-poor northern regions, they can be considered biological hotspots. Unfortunately, these areas have been degraded and destroyed. In recent years, however, the biological importance of wetlands has been increasingly recognized, resulting in the desire to restore disturbed habitats or create in place of destroyed ones. Restoration work is taking place across the globe in a diversity of wetland types, and research must be conducted to determine successful techniques. As a result, two studies of the effects of wetland restoration and creation were conducted in forested wetlands in northern Michigan and southern Finland. In North America, northern white-cedar wetlands have been declining in area, despite attempts to regenerate them. Improved methods for successfully establishing northern white-cedar are needed; as a result, the target of the first study was to determine if creating microtopography could be beneficial for white-cedar recruitment and growth. In northern Europe, spruce swamp forests have become a threatened ecosystem due to extensive drainage for forestry. As part of the restoration of these habitats, i.e. rewetting through ditch blocking, Sphagnum mosses are considered to be a critical element to re-establish, and an in-depth analysis of how Sphagnum is responding to restoration in spruce swamp forests has not been previously done. As a result, the aim of the second study was to investigate the ecophysiological functioning of Sphagnum and feather mosses across a gradient of pristine, drained, and restored boreal spruce swamp forests.

Application of ultra high performance concrete (UHPC) as a thin-bonded overlay for concrete bridge decks

As transportation infrastructure across the globe approaches the end of its service life, new innovative materials and applications are needed to sustainably repair and prevent damage to these structures. Bridge structures in the United States in particular are at risk as a large percentage will be reaching their design service lives in the coming decades. Superstructure deterioration occurs due to a variety of factors, but a major contributor comes in the form of deteriorating concrete bridge decks. Within a concrete bridge deck system, deterioration mechanisms can include spalling, delaminations, scaling from unsuitable material selection, freeze-thaw damage, and corrosion of reinforcing steel due to infiltration of chloride ions and moisture. This thesis presents findings pertaining to the feasibility of using UHPC as a thin-bonded overlay on concrete bridge decks, specifically in precast bridge deck applications where construction duration and traffic interruption can be minimized, as well as in cast-in-place field applications. UHPC has several properties that make it a desirable material for this application. These properties include post-cracking tensile capacity, high compressive strength, high resistance to environmental and chemical attack, negligible permeability, negligible dry shrinkage when thermally cured, and the ability to self consolidate. The compatibility of this bridge deck overlay system was determined to minimize overlay thickness and dead load without sacrificing bond integrity or lose of protective capabilities. A parametric analysis was conducted using a 3D finite element model of a simply supported bridge under HS-20 truck and overload. Experimental tests were conducted to determine the net effect of UHPC volume change due to restrained shrinkage and tensile creep relaxation. The combined effects from numerical models and test results were then considered in determining the optimum overlay thickness for cast-in-place and precast applications.

Quickbird satellite imagery for riparian management : characterizing riparian filter strips and detecting concentrated flow in an agricultural watershed

Riparian ecology plays an important part in the filtration of sediments from upland agricultural lands. The focus of this work makes use of multispectral high spatial resolution remote sensing imagery (Quickbird by Digital Globe) and geographic information systems (GIS) to characterize significant riparian attributes in the USDA’s experimental watershed, Goodwin Creek, located in northern Mississippi. Significant riparian filter characteristics include the width of the strip, vegetation properties, soil properties, topography, and upland land use practices. The land use and vegetation classes are extracted from the remotely sensed image with a supervised maximum likelihood classification algorithm. Accuracy assessments resulted in an acceptable overall accuracy of 84 percent. In addition to sensing riparian vegetation characteristics, this work addresses the issue of concentrated flow bypassing a riparian filter. Results indicate that Quickbird multispectral remote sensing and GIS data are capable of determining riparian impact on filtering sediment. Quickbird imagery is a practical solution for land managers to monitor the effectiveness of riparian filtration in an agricultural watershed.
