ARTGEO: ensino interdisciplinar

The ARTGEO Project aimed at integrating science, art, and technology, emphasizing geometric elements which must be explored within the teaching process. Geometry, present in the most primitive civilizations, assists man in settling relationships and organizing his space. It has been clearly identified in human constructions, consisting of an important instrument of knowledge and domain of nature. The art, in its turn, can mediate the elaboration of knowledge, whether it is scientific, technical, or philosophical. Science and art are products that express the imaginary representations from distinct cultures. The Brazilian Concretism, for its relations with the geometry, is the period in art history chosen as reference. Technology was represented by the computational environments, as a didactic support and an instrument for the accomplishment of practical activities. Microsoft Word is one of the basic softwares for this proposal because of its easy access in most public schools.

Arte reversa: aplicando a engenharia reversa na arte

This study aimed to examine the reverse engineering and respond to a concern about the possible application of this concept in art, breaking down barriers and breaking paradigms. Using 3D scanning, the art of computer aided design and manufacturing – CAD/CAM, machining by computer numerical control - CNC, engineering, and applying this methodology in the arts especially in sculpture, it is possible to dematerialize a artwork, virtualizes it in 3D programs, make speeches, and process a new work, a new art elsewhere. By the example of surgeries at a distance, the artist, or technical author could produce their works, and materialize them anywhere. In other words, do the reverse gear. It discusses the relationship between art and technology, the role of the author, the viewer, which can interfere with the interactivity that case by stating that art, exists only in the look and feel of the viewer.

Geoprocessamento aplicado na determinação das áreas de preservação permanente e áreas de conflito com cultivo agrícola no município de Lençóis Paulista/SP

The city of Lençóis Paulista has a great part of its agricultural land cultivated by sugar cane and reforestation of eucalyptus and pine trees. In the county there are industries that exploit energy extracted from energy cogeneration. The city of Lençóis Paulista, in recent years, has been demonstrating considerable levels of economic and social growth with the industries that are working with sugarcane and eucalyptus mainly responsible. However, the expansion of agricultural land in many cases does not take into consideration the permanent preservation areas that are protected by the law. The APP's are of fundamental importance in the management and conservation of the environment preserving the natural plants and wildlife, and also preventing erosion and the silting of drainage networks. This objective of this study was to diagnose land use, analyze if Permanent Preservation Areas are regulated to the Brazilian Forestry Code (1965) and also diagnose areas of conflict. In relation to the use and occupation of land, the research has shown how the land is divided (agricultural crops and urban zones), and highlighted areas of conflict with the Permanent Preservation Areas. All of the information is contained in maps using Geographic Information Systems. However, it has become clear that environmental laws are not respected as much in urban areas as they are in rural areas. The PPA's are virtually nonexistent, thus creating damage to the environment and local population.

Dormancy breaking of the fig tree with hydrogen cyanamide and garlic extrate

The supply of cold hours needed to the dormancy breaking of shoots is the limiting factor for the cultivation of temperate climate fruit trees in warmer regions. In subtropical conditions, it is necessary to use chemical products to promote uniform sprouting. This research aimed at evaluating the effect of garlic extract and hydrogen cyanamide in sprouting, growth, production and production cycle of the fig tree. The experiment was conducted during the production cycles of 2011/12 and 2012/13. We used plants from the cultivar Roxo de Valinhos. Production pruning was made in the months of July/2011 and July/2012, and the following treatments were applied immediately after it: 2% hydrogen cyanamide and garlic extract in 4%, 8% and 12% doses, and a control treatment. Split plots were used as the experimental design, with five repetitions in blocks; each plot consisted of five treatments with hydrogen cyanamide, garlic extract and control; the subplots consisted of two production cycles. The use of hydrogen cyanamide promoted an anticipation of sprouting and the use of hydrogen cyanamide and garlic extract promoted a concentration of the productive period, when compared to the control. The estimated garlic extract dose that promoted the highest production per plant was 3%.

Master Conservationist Presentations - 2003

We begin our Master Conservationist recognition in Production Agriculture with the Buskirk Family of Hemingford in the Panhandle. Will David and Toni Buskirk, Dean and Sonya Buskirk, Chad Buskirk, and Dustin and Shelly McConville, please come forward? They started with a half-section which has grown to 2,855 acres, as well as a tree-planting business. The family formed a partnership in 1995 and named it “Trees are Us” in 1998. They have used no-till farming on 1,000 acres of cropland since 1980 and planted over 165,000 trees. A low-pressure irrigation system saves about 400 acre inches of water every growing season. They built their own no-till tree planter for differing soil conditions and a machine to install biodegradable weed barriers. Their enthusiasm for trees is contagious as they visit with others and perform volunteer work in the area. Their unique tree planting equipment is made available nationwide, which results in the planting of more than 2 million trees in over 10 states annually. Congrats to the Buskirks.

Use of Confined Dogs for Reducing Deer Damage to Apple Orchards

We assessed the efficacy of free-ranging dogs, confined by buried fences and electronic collars, for reducing deer damage to apple trees in three commercial apple orchards in Oswego County, New York State. During 1995 and 1996, we monitored paired dog-protected and control plots in each orchard. Within dog-protected areas, the percentage of damaged buds was lower, and fruit yield was higher in both 1995 and 1996 than for control plots. Gross economic returns were higher from dog-protected than control plots in both 1995 (by 51%) and 1996 (by 184%). After two seasons of growth, trees planted in May 1995 had nearly three times the cross-sectional area, and were 60% taller if they were in dog-protected rather than control plots. Dogs provided increased economic returns for growers at much lower cost than conventional barrier fencing.

Tropical, de Anita Malfatti

A partir da análise de Tropical, tela pintada por Anita Malfatti em 1917, este artigo propõe que a artista procedia a uma mudança em sua linguagem pictórica, afastando-se das concepções de vanguarda que adotara até então para, aderindo ao clima de retorno à ordem internacional, aproximar-se das discussões sobre o nacionalismo na arte, presentes na cena paulistana. Assim, a imagem de mulher insegura que mudou sua perspectiva por causa da crítica de Monteiro Lobato adquire outra conotação. Os modernistas teriam preferido essa interpretação a efetuar uma análise da obra de Anita Malfatti, por meio da qual se poderia desvelar uma deserção do programa vanguardista feita de forma consciente pela artista

Los objetos de aprendizaje en la enseñanza del vocabulario específico del inglés para la Conservación y Restauración

[ES]En la docencia de inglés del Grado en Conservación y Restauración de la Universidad de La Laguna (España), se ha constatado la inexistencia de recursos didácticos comerciales adecuados para este ámbito concreto, en particular para el aprendizaje del léxico especializado. Ante esta situación, como suele suceder en el campo del inglés para fines específicos, se ha acometido la creación gradual de materiales propios, empleando tecnologías de la información y de la comunicación (TIC). La experiencia acumulada durante los tres primeros años de andadura de la titulación, en los que los materiales TIC sirvieron de apoyo a la docencia presencial de grupos muy heterogéneos, ha conducido al planteamiento de la presente investigación.

Application of FTIR microscopy to cultural heritage materials

Research in art conservation has been developed from the early 1950s, giving a significant contribution to the conservation-restoration of cultural heritage artefacts. In fact, only through a profound knowledge about the nature and conditions of constituent materials, suitable decisions on the conservation and restoration measures can thus be adopted and preservation practices enhanced. The study of ancient artworks is particularly challenging as they can be considered as heterogeneous and multilayered systems where numerous interactions between the different components as well as degradation and ageing phenomena take place. However, difficulties to physically separate the different layers due to their thickness (1-200 µm) can result in the inaccurate attribution of the identified compounds to a specific layer. Therefore, details can only be analysed when the sample preparation method leaves the layer structure intact, as for example the preparation of embedding cross sections in synthetic resins. Hence, spatially resolved analytical techniques are required not only to exactly characterize the nature of the compounds but also to obtain precise chemical and physical information about ongoing changes. This thesis focuses on the application of FTIR microspectroscopic techniques for cultural heritage materials. The first section is aimed at introducing the use of FTIR microscopy in conservation science with a particular attention to the sampling criteria and sample preparation methods. The second section is aimed at evaluating and validating the use of different FTIR microscopic analytical methods applied to the study of different art conservation issues which may be encountered dealing with cultural heritage artefacts: the characterisation of the artistic execution technique (chapter II-1), the studies on degradation phenomena (chapter II-2) and finally the evaluation of protective treatments (chapter II-3). The third and last section is divided into three chapters which underline recent developments in FTIR spectroscopy for the characterisation of paint cross sections and in particular thin organic layers: a newly developed preparation method with embedding systems in infrared transparent salts (chapter III-1), the new opportunities offered by macro-ATR imaging spectroscopy (chapter III-2) and the possibilities achieved with the different FTIR microspectroscopic techniques nowadays available (chapter III-3). In chapter II-1, FTIR microspectroscopy as molecular analysis, is presented in an integrated approach with other analytical techniques. The proposed sequence is optimized in function of the limited quantity of sample available and this methodology permits to identify the painting materials and characterise the adopted execution technique and state of conservation. Chapter II-2 describes the characterisation of the degradation products with FTIR microscopy since the investigation on the ageing processes encountered in old artefacts represents one of the most important issues in conservation research. Metal carboxylates resulting from the interaction between pigments and binding media are characterized using synthesised metal palmitates and their production is detected on copper-, zinc-, manganese- and lead- (associated with lead carbonate) based pigments dispersed either in oil or egg tempera. Moreover, significant effects seem to be obtained with iron and cobalt (acceleration of the triglycerides hydrolysis). For the first time on sienna and umber paints, manganese carboxylates are also observed. Finally in chapter II-3, FTIR microscopy is combined with further elemental analyses to characterise and estimate the performances and stability of newly developed treatments, which should better fit conservation-restoration problems. In the second part, in chapter III-1, an innovative embedding system in potassium bromide is reported focusing on the characterisation and localisation of organic substances in cross sections. Not only the identification but also the distribution of proteinaceous, lipidic or resinaceous materials, are evidenced directly on different paint cross sections, especially in thin layers of the order of 10 µm. Chapter III-2 describes the use of a conventional diamond ATR accessory coupled with a focal plane array to obtain chemical images of multi-layered paint cross sections. A rapid and simple identification of the different compounds is achieved without the use of any infrared microscope objectives. Finally, the latest FTIR techniques available are highlighted in chapter III-3 in a comparative study for the characterisation of paint cross sections. Results in terms of spatial resolution, data quality and chemical information obtained are presented and in particular, a new FTIR microscope equipped with a linear array detector, which permits reducing the spatial resolution limit to approximately 5 µm, provides very promising results and may represent a good alternative to either mapping or imaging systems.
