O Caso Ouro Fino Saúde Animal ilustra uma tomada de decisão, pelos executivos da empresa, sobre a entrada em um novo mercado, de vacinas para bovinos. Diante da necessidade de dar um passo maior em direção ao crescimento sustentável, a empresa não poderia deixar de entrar nesse segmento, que representava mais de metade do mercado brasileiro de produtos veterinários. No entanto, era um passo arriscado. A principal questão do caso é avaliar as alternativas de comprar vacinas de terceiros ou produzir internamente suas próprias vacinas. A empresa do caso é a Ouro Fino Saúde Animal, empresa brasileira de produtos veterinários, instalada no Estado de São Paulo, com faturamento de mais de R$ 100 milhões anuais. Os dois principais personagens deste caso são os diretores financeiro e industrial da empresa. A situação passa-se em 2005. Como instrumento de ensino, o caso foi concebido para o ensino de estratégia em cursos de pós-graduação em administração, levando os alunos a avaliar vantagens e desvantagens de cada uma das alternativas. Como objetivo secundário, o caso propicia alguns elementos para uma estimativa da viabilidade financeira da opção de implantar uma nova unidade produtiva e a possibilidade de refletir sobre uma decisão já tomada, de entrada no novo mercado. Por fim, o caso traz uma série de informações sobre o mercado brasileiro e sobre o mercado mundial de produtos veterinários. É possível, com base nestes dados, trabalhar questões ligadas à segmentação e posicionamento da empresa no setor, ficando a critério do professor este tipo de uso.

The petrographic study of rocks of Ouro Fino unit’s Nova Lima group, Greenstone Belt Rio das Velhas, on interior of Quadrilatero Ferrifero, cointains few affected samples by alterations processes. Many rocks have the primary features like lavas in pillow, tonsils and pox. The petrographic analysis classifies the rocks in tholeiitic basalt and magnesium tholeiite. Unidade Ouro Fino’s metabasalts are from ocean bottom ambiente shown by structures (pillow lava) and lithologic associations (banded iron formation and metachert). A few minerals was recognized in petrographic thin section allowing the description of its mineral paragenese and a needed classification.The geochemical characteristics consulted in the literature indicate that part of the metabasalts was formed by a mantle plume (P-MORB). These characteristics infer a submarine plateau ambient.

O café é a segunda bebida mais consumida no mundo e no Brasil, o País se destaca como sendo o maior produtor de café do mundo. Segundo a Confederação da Agricultura e Pecuária, o cacau é uma fruta nativa da Amazônia, sua amêndoa é utilizada para a produção do pó e da manteiga de cacau. Ambos cultivos possuem problemáticas semelhantes como escravidão contemporânea para colheita e produção dos frutos e exploração dos recursos naturais, no caso do café, uso intenso de agrotóxicos. A Rainforest Alliance é uma organização internacional que trabalha para combater o desmatamento, garantir os direitos dos trabalhadores, etc. Este estudo teve como objetivo quantificar a porcentagem de embalagens de cafés e chocolates em barra que expõe o selo Rainforest Alliance no comércio varejista alimentício nas cidades de Ouro Fino e Pouso Alegre, do Estado de Minas Gerais. A porcentagem de chocolates em barra com o selo de sustentabilidade ambiental foi superior aos dos tipos de café Torrado e moído e Solúvel, e o chocolate em barra tipo Meio Amargo apresentou 21% de produtos certificados.

In equatorial and tropical regions, supergene mineral deposits created during water/rock interactions are found. Simply put, these supergene deposits are formed through the accumulation of low solubility ions or through the preservation of primary minerals. The supergene manganese (Mn) deposits are examples of the economic importance associated with the chemical weathering processes. In Brazil, the Southern Brasilia Orogen (SBO) was generated during the collision between the Paranapanema Craton and the passive margin of the São Francisco Craton. In the southern Minas Gerais (MG), several supergene Mn occurrences are hosted in the SBO, which were originated during the chemical weathering of gondites belonging to the Amparo Complex. Here, we studied the supergene Mn occurrences in the southern MG, more specifically in the municipalities of Ouro Fino and Careaçu. The MnO contents ranged from 25.50 to 28.40 wt% at Ouro Fino and from 16.80 to 21.20 wt% at Careaçu. These supergene Mn deposits have a diverse mineral assemblage, being composed of spessartine, quartz, Mn-oxides, goethite and kaolinite. The various Mn minerals formed due to spessartine incongruent dissolution were hollandites, cryptomelanes, romanechites, pyrolusites and lithiophorites. Both study areas are relevant for the possible opening of mines for the commercialization of Mn.

This study aimed to explore changes in follicle diameter and blood flow of the dominant follicle (DF), in ovulation and embryo transfer rates, after inclusion of eCG in a protocol for timed embryo transfer. The effect presence or absence of a corpus luteum (CL) at the start of treatment was also included. Crossbred heifers (n = 116, Bos taurus × Bos indicus), with (n = 61) or without (n = 55) CL, were included in the same hormone protocol: Day 0 (D0), insertion of progesterone (P4) device (1.0 g, Sincrogest®, Ouro Fino, São Paulo, Brazil) and 2 mg of oestradiol benzoato (EB, Sincrodiol®, Ouro Fino); D8, removal of P4 device and injection of sodium Cloprostenol (0.250 mg mL–1, Sincrocio®, Ouro Fino). On D8, the animals with and without CL – at the beginning of the protocol – were equally divided into 2 groups (G): G1 – injection of 300 IU (2.0 mL) of eCG (n = 56; Synchro eCG®, Ouro Fino); G2 – 2.0 mL of saline (n = 60). The ovulations were synchronized with 1 mg of EB on D9. From D8 to D11, the diameter of the DF and blood flow in its wall were recorded daily (M5 ultrasound with colour Doppler technology, 7.5-MHz linear array, DPS medical equipment, São Paulo, Brazil). Approximately 100 frames in colour-flow mode, containing entire cross-sections of the DF, were recorded during each examination. The area of the follicular wall with coloured pixels was measured with ImageJ software (Image Processing and Analysis in Java) from the frame with the largest blood flow signal. Before embryo transfer, all heifers were evaluated, and those with good-quality CL received frozen/thawed embryos (ethylene glycol 1.5 mol). Follicle diameter and blood flow area were compared between groups with or without CL before timed embryo transfer protocol and between eCG treatments. The PROC GLM procedure of SAS (version 9.0) and the t-test were used to assess the differences between means. Pregnancy diagnosis was performed on D35. Embryo transfer (ET) rate of the recipients and pregnancy rate were compared between CL or eCG treatments by the chi-squared test. Ovarian status, before hormone protocol, did not change (P > 0.05) the follicular growth of the DF. However, ovulation rate (78.8 v. 65.4%, P < 0.05) and ET rate (78.7 v. 65.4%, P < 0.05) were higher in animals with CL on D0. From D8 to D10, the inclusion of eCG did not affect (P > 0.05) follicular growth and blood flow of the DF. The time effect (P < 0.0001) for follicular blood flow had shown an increase in area of blood flow 24 h after implant removal (7.7 ± 0.7,b 10.2 ± 0.7,a and 12.3 ± 1.0a mm2, for Days 8, 9, and 10, respectively). The eCG did not affect (P > 0.05) the ovulation rate (71.4 and 73.3%, respectively, eCG and no eCG), however, approached an increased (P < 0.06) ET rate (78.8 v. 66.7%). The overall pregnancy rate (51.2%, 43/84) was not affected (P > 0.05) by evaluated variables. In summary, the addition of 300 IU of eCG on D8 of the timed embryo transfer protocol did not change the development of DF but increased the ET rate of the recipients. Biotran, FAPEMIG (project number APQ-1454-12), and CnPQ are acknowledged.

Resumo: As discussões sobre "novas" ruralidades chamam a atenção para as outras funções, significados e atribuições do espaço rural, não mais visto apenas como local de produção agrícola, mas também como portador de tradições e, sobretudo, de uma natureza a ser conservada. Nesse sentido, a agricultura familiar é evocada como potencialmente mais diversificada, menos daninha ao equilíbrio natural e mais propensa à conservação de uma paisagem compatível com a imagem de mundo rural buscada pelos citadinos. No contexto brasileiro, acreditamos que essa discussão deva ser permeada pela análise de como processos diferenciados de distribuição fundiária e desenvolvimento econômico e o tipo de agricultura resultante geram ruralidades específicas com características como, no caso da agricultura familiar, a manutenção de práticas sociais e de trabalho marcadas pelas relações de parentesco e vizinhança presentes numa sociedade de interconhecimento. É nesse caminho que segue esse trabalho ao analisar a agricultura familiar do município de Ouro Fino - MG através do estudo de um de seus muitos bairros rurais usando como metodologia básica a análise de sistemas agrários. Saber quem são os agricultores familiares, que atividades exercem, que área ocupam, que projetos e esperanças guardam para o futuro e para os filhos pode ajudar a esclarecer que tipo de ruralidade aquela realidade específica gera e qual seu potencial para atrair outras categorias sociais e outras atividades econômicas distintas ou complementares à agricultura. Corroborando com os autores que defendem a existência de pontos de continuidade e ruptura entre a agricultura familiar e o campesinato a pesquisa aqui apresentada examina de que forma a herança camponesa persiste no contexto de uma agricultura familiar modernizada e totalmente integrada ao mercado de insumos e produtos. É essa continuidade com o passado camponês que permite a manutenção de uma paisagem diversificada e atraente e assegura a persistência de laços de solidariedade encontrados nas relações entre os habitantes do bairro e entre comunidades vizinhas tanto na realização do trabalho como por ocasião das festas em louvor ao santo padroeiro
Abstract: The debate about "new" ruralities calls attention to the other functions, meanings and destinations of rural spaces now seen not only as the place for agricultural production, but carrying traditions and a natural richness that must be preserved. In that sense family farming is evoked as potentially more diversified, less dangerous to the natural balance and more prone to keep a rural atmosphere compatible with the image of the countryside seeked by urban people. In the Brazilian context we believe that such debate must be permeated by the analyses of how differentiated processes of land distribution and economic development and the resulting kind of agriculture generate specific ruralities with characteristics such as, in the case of family farming, the maintenance of social and work practices marked by the relations among relatives and neighbours present in a interrelation society. This work follows that path, analyzing family agriculture in Ouro Fino - MG through the study of one of its many rural neighbourhoods and using the agrarian systems analyses as basic methodology. To know who the family farmers are, what are their activities, what area they occupy, what projects and hopes they keep for the future and for their children can help clarify the kind of rurality a specific reality creates and what potential it has to attract other economic activities distinct and complementary to agriculture. Corroborating with authors that defend the existence of points of continuity and rupture between family agriculture and peasantry the research here presented examines the way in which the peasant heritage persists in the context of a modern family agriculture totally integrated in the market economy. It is this continuity with the peasant heritage that allows the permanence and the preservation of a diversified and attractive environment and assures the persistence of solidarity bonds found in work and social relations among local inhabitants and neighbour communities

Na região a norte de Ouro Fino, extremo sudoeste do Estado de Minas Gerais, foi individualizada, ao longo de uma faixa de orientação aproximada EW e largura média de 6,5 km, uma seqüência meta-vulcano-sedimentar proterozóica. Litoestratigraficamente, caracteriza-se por um conjunto de 9 unidades que foram agrupadas, da base para o topo, em quatro seqüências principais: seqüência gnáissica inferior (unidade dos biotita gnaísses tonalíticos); seqüência xisto-quartzítica (unidades dos quartzitos placosos e biotita xistos quartzo-feldspáticos); seqüência gnáissica intermediária (unidade dos gnaisses bandados); e seqüência gnáissico-quartzítica (unidades dos biotita gnaisses quartzosos, hornblenda-biotita gnaisses ocelares, muscovita-quartzo-biotita xistos, muscovita quartzitos e anfibolitos com gnaisses cálcio-silicáticos). A equivalência e continuidade física dessa seqüência meta-vulcano-sedimentar com as unidades do Grupo Andrelândia (da região que lhe empresta o nome) puderam ser evidenciadas a partir da correlação do empilhamento litoestratigráfico e de levantamentos regionais de campo. Uma unidade ortognáissica pré-tectônica intrusiva no Grupo Andrelândia se apresenta como corpos tabulares concordantes e, em geral, de grande extensão lateral. Informalmente denominada de granito-gnaisses Taguar, essa unidade é constituída por ferrohastingsita-piroxênio granitos, biotita-ferrohastingsita granitos e granodioritos e ferrohastingsita-biotita granitos, todos gnáissicos e portadores de magnetita. As unidades do Grupo Andrelândia e os granito-gnaisses Taguar registram uma história deformacional com 5 fases superpostas de dobramentos. A primeira fase (D1) tem como registro principal uma foliação tectônica S1 preservada de modo reliquiar; dobras referentes a esta fase, não foram encontradas, e sua orientação e vergência tectônica são desconhecidas. A organização estrutural do Grupo Andrelândia está controlada por uma articulação de nappes de dobramento atribuíveis à segunda fase (D2), que tem seus elementos lineares orientados preferencialmente segundo N55E-S55W, indicando um sentido de transporte tectônico aproximado de N35W. Essas duas primeiras fases desenvolveram-se sob condições metamórficas da fácies anfibolito médio (primeira isógrada da sillimanita), sinformas e antiformas normais, abertas e apertadas, desenhadas pela foliação principal das unidades do Grupo Andrelândia e pelos seus contatos correspondem às fases de dobramentos tardios superpostos D3, D4 e D5, que são orientados, respectivamente, segundo NE/SW, WNW-ESSE e NNE-SSW. A fase D3 do Grupo Andrelândia corresponde à fase D1 dos meta-sedimentos da Formação Eleutério-Pouso Alegre e se desenvolveu sob condições da fácies xisto verde, Zonas lineares de cisalhamento tiveram um desenvolvimento penecontemporâneo a parte das fases de dobramento. A partir da análise litoestratigráfica regional do Grupo Andrelândia e correlatos são caracterizadas, na Faixa Alto Rio Grande, três zonas isópicas principais, alongadas segundo a direção média ENE e denominadas, das porções esternos para as internas da Faixa, de Grupo São João Del Rey, Grupo Andrelândia e Grupo Itapira. Em cada uma destas zonas são descritos diversos estágios evolutivos (de \"rift\" a plataforma e a vulcânico \"flysch\") parte admitindo referência paleogeográfica no paleocontinente \"São Francisco\", parte nas porções internas da Faixa. Ao lado das diferenças individuais entre seus estágios equivalentes, reconhece-se um diacronismo no estabelecimento e desenvolvimento das três zonas isópicas. Os dados geocronológicos disponíveis para as unidades do Grupo Andrelândia, seu embasamento e os granito-gnaisses Taguar permitem posicionar a Faixa Alto Rio Grande no Proterozóico Médio. Para o período de estabelecimento e desenvolvimento paleogeográfico reconhece-se como limites inferior e superior, respectivamente, os intervalos de 1.900 - 1.800 m.a. e 1.500 - 1.400 m.a.. O primeiro evento tectônico, responsável pelo desenvolvimento da foliação S1 e de prováveis inversões paleogeográficas, deve ter ocorrido em torno de 1.400 m.a.. Para o segundo evento tectônico, responsável pela organização estrutural principal da Faixa Alto Rio Grande e pelo \"underthrusting\" da mesma sob os terrenos da Nappe de Empurrão Socorro-Guaxupé, os dados existentes não são conclusivos, ora sugerindo idades entre 1.200 e 1.00 m.a., ora entre 850 e 800 m.a.. Como limite superior seguro para os eventos tardi-tectônicos é reconhecido o intervalo de 500-550 m.a.In the Ouro Fino region, southwestern Minas Gerais state, a Proterozoic metavolcanosedimentary sequence was individualized along a belt of approximately EW orientation and with average width of about 6.5 km, Lithostratigraphically it is characterized by 9 units which were grouped, from base to top, into four main sequences: lower gneissic sequence (tonalitic biotite gneisses unit); schist-quartzitic sequence (platy quartzites and quartzofeldspathic biotite schists unit); intermeadiate gneissic sequence (banded gneisses unit); and gneissic-quartzitic sequence (quartz-rich biotite gneisses, hornblende-biotite augen gneisses, muscovite-quartz-biotite schists; muscovite quartzites and amphibolites with calc-silicatic gneisses units). Based on the lithostratigraphic correlation and regional field work, the equivalence and physical continuity of this metavolcanosedimentary sequence with the Andrelândia Group (from the homonymous region) can be established. A pre-tectonic orthogneissic unit, intrusive into the Andrêlandia Group, occurs as tabular, concordant bodies and generally with large lateral extension. This unit, informally named as Taguar granite-gneisses, consists of ferrohastingsite-pyroxene granites, biotite-ferrohastingsite granite-granodiorites, and ferrohastingsite-biotite granites, all of them gneissic and magnetite-bearing. The Andrelândia Group sequences and the Taguar granite-gneisses were deformed by 5 superposed folding phases. The first phase (\'D IND.1\') has a reliquiar \'S IND.1\' tectonic foliation preserved, but folding related to this phase has not been found and its orientation and tectonic vergence are unknown. The structural organization of the Andrelândia Group is controlled by folding nappes attributed to the second phase (\'D IND. 2\'), with N55E-S55W oriented linear elements indicating a tectonic transport towards about N35W. These two phases were developed under middle-amphibolite facies conditions (first isograd of sillimanite). Normal synforms and antiforms, open to tight, showed by the main foliation of the Andrelândia Group units and by their contacts, correspond to the superposed late \'D IND. 3\', \'D IND. 4\' and \'D IND.5\' phases, which are oriented NE-SW, WNW-ESE and NNE-SSW, respectively. The \'D IND. 3\' phase of the Andrelândia Group corresponds to the \'D IND. 1\' phase of the Eleutério-Pouso Alegre Formation metasediments and was developed under greenschist facies condition. Linear shear zones had a coeval development to some of these folding phases. Three main isopic zones, elongated along an ENE direction, are characterized in the Alto Rio Grande Belt, based on the regional lithostratigraphic analyses of the Andrelândia Group and correlates. These zones are named, from the external to the internal portions of the belt, as São João del Rei, Andrelândia, and Itapira groups. Each of these zones have several evolutionary stages (from rifting to platformal sedimentation to flysch-volcanic stage), some of them with paleogeographic reference to the \"São Francisco\" paleocontinent while others to internal portions of the belt. Besides individual differences between equivalent stages, a diachronism in the establishment and development of the three isopic zones is recognized. The existing geochronological data for the Andrelândia Group units, their basement and the Taguar granite-gneisses suggest that the Alto Rio Grande Belt is of Middle-Proterozoic age. The lower and upper limits for the paleogeographic establishment and development, are considered the 1,900 - 1,800 Ma and 1,500 - 1,400 Ma intervals, respectively. The first tectonic event, responsible for the \'S IND. 1\' foliation and probable paleogeographic inversions, should have occurred at about 1,400 Ma ago. For the second tectonic event, responsible for the main structural organization of the Alto Rio Grande Belt and its underthrusting beneath the terrains of the Socorro-Guaxupé Thrust Nappe, the available data is inconclusive suggesting either 1,200 - 1,000 Ma or 850 - 800 Ma age intervals. The late-tectonic events have a well defined 550 - 500 Ma interval upper limit.

Os depósitos Cocal e Ouro Fino são constituídos por um sistema de veios de quartzo auríferos controlados estruturalmente, situados na lapa e capa, respectivamente da Falha do Rio Maranhão. Estão hospedados em sequencias sedimentares metamorfisadas dos grupos Paranoá e Serra da Mesa. São parte integrante de um importante orógeno acrescionário representado pela Província Tocantins – Faixa Brasília, construído de forma contínua, progressivamente, ao longo do final da Orogenia Brasiliana. As rochas identificadas nas áreas são representadas por xistos, filitos, quartzitos e calcários, as três primeiras hospedeiras do sistema mineralizado. Essas rochas foram metamorfisadas na fácies xisto verde, zonas da clorita e biotita. Os veios de quartzo auríferos foram objeto de explotação desde o século XVIII e alguns locais são minerados por garimpeiros até hoje. Empresas de mineração desenvolvem atualmente trabalhos de pesquisa nas áreas e reportam teores de até 45 g/t de ouro. Foram identificados três momentos principais de deformação nos depósitos estudados. O primeiro, um momento compressivo na direção EW desenvolvido em litosfera predominantemente dúctil, gerador da foliação S1, de caráter regional, pervasivo, com geração de venulações de quartzo-carbonato, mineralização aurífera em zona de cisalhamento de baixo ângulo, dobramentos isoclinais, achatamento e estiramento das estruturas em regimes coaxial a não coaxial. Um segundo momento de deformação em condições de litosfera rúptil – dúctil, com geração de fraturas extensionais onde ficaram alojados os veios de quartzo (±carbonato) auríferos, reativando também estruturas antigas. Um terceiro momento, marcado por deformação rúptil, que gerou fraturas e falhas, algumas profundas, preenchidas por diques básicos magnéticos. Foram identificadas três famílias principais de venulações e veios de quartzo (± carbonato). Uma sintectônica ao primeiro momento de deformação (S1), aqui denominada Veios Sintectônicos (VST), com mineralização aurífera associada localmente. Um sistema formado por duas famílias associadas à formação de fraturas extensionais no segundo momento de deformação, mineralizada a ouro, denominadas Veios Tarditectônicos VTT1 (Cocal) e VTT2 (Ouro Fino). No Depósito Cocal o ouro ocorre livre e/ou incluso em massas ou cristais subédricos de pirita com porcentagens de prata entre 4,87 e 17,69%. Alteração hidrotermal provocou enriquecimento nas rochas em Si (quartzo), Ca (carbonatos), K (micas), B (turmalinas), S (sulfetos), Fe (pirita, magnetita), ouro e prata. A geoquímica de isótopos de carbono, oxigênio e enxofre do Depósito Cocal parece excluir a possibilidade dos metais e fluidos mineralizantes serem originados da crosta inferior (ou manto) ou carbono orgânico em sedimentos e sugerem a sua derivação de fontes na crosta superior, especialmente de sedimentos químicos (calcários marinhos). A concentração regional de mineralizações auríferas no grupo Paranoá e Serra da Mesa, próximas ao traço da Falha do Rio Maranhão, permite traçar um Cinturão de Ouro Orogênico, pelo menos no setor setentrional da Faixa Brasília. Os depósitos Cocal e Ouro Fino apresentam controles litológicos e estruturais que permitem enquadra-los nos Depósitos de Ouro Orogênico descritos por Mitchell & Garson, (1981) e Groves et al. (1998).
The Cocal and Ouro Fino deposits are comprised of a system of structurally controlled gold bearing quartz veins situated in the footwall and hangingwall respectively of the Rio Maranhão Fault. These deposits are hosted by the metamorphosed sediments of the Paranoá e Serra da Mesa Groups. These Groups are an important part of the Brasília Belt colisional accretionary orogen of the Tocantins Province and formed progressively in the concluding stages of the Brasiliano Orogeny. Rock types identified within the area are schists, phyllites, quartzites and carbonates with the first three hosting the mineralised system. These rocks were metamorphosed to greenschist facies , chlorite and biotite zones. The gold bearing quartz veins have been worked since the 18th Century and some areas are still being worked by informal miners (‘Garimpeiros’). Several Mining Companies have conducted exploration work within the area and have reported grades of up to 45 grams/Tonne of gold. Three principal phases of deformation have been identified in the deposits studied. The first phase was a compressive event in an E-W direction developed in a principally ductile lithosphere and generating the S1 foliation with a regional and pervasive character and generating veinlets of quartz-carbonate, gold mineralisation in low angle shear zones, isoclinal folds, flattening and stretching in coaxial or non-coaxial regimes. A second phase of deformation under brittleductile lithosperic conditions generated extensional fractures which host veins of gold bearing quartz (±carbonate), and also reactivated older structures. A third phase of brittle deformation generated fractures and faults, some quite deep, and intruded by basic magnetic dykes. Three principal families of quartz (± carbonate) veins and veinlets have been identified. The first family is syn-tectonic with S1 deformation and is locally gold bearing and is designated as Syn-tectectonic Veining (VST). A system made up of two vein families with gold mineralisation is associated with the generation of extensional fractures during the second phase of deformation, and is denominated as Late Tectonic Veining VTT1 (Cocal) and VTT2 (Ouro Fino). In the Cocal Deposit gold occurs free and/or as inclusions in masses or within subhedral crystals of pyrite and with silver contents from 4.87 to 17.69%. Hydrothermal alteration has resulted in enrichment of the rocks in Si. (quartz), Ca. (carbonates), K. (micas), B. (tourmalines), S. (sulphides), Fe. (pyrite, magnetite), gold and silver. Preliminary isotope geochemistry of carbon, oxygen and sulphur from the Cocal Deposit seems to exclude the possibility that mineralising fluids originated in the lower crust (or mantle) or from organic carbon in sediments and suggest the fluids originated in the upper crust and especifially from chemical sediments (marine limestones). The regional concentration of gold mineralisation within the Paranoá and Serra da Mesa Groups along the trace of the Rio Maranhão Fault allows the definition of an Orogenic Gold Belt at least in the northern part of the Brasília Belt. The Cocal and Ouro Fino deposits show lithological and structural controls which allow them to be classed as Orogenic Gold Deposits as described by Mitchell & Garson (1981) and Groves et al. (1998).

Previous issue date: 2009-08-10This work aims to study the three landscapes in Arraial de Ouro Fino - which originated with the cycle of mining in Goiás, in the middle of the eighteenth century, and collapsed in the final half of the twentieth century - observing the Archaeological Landscape, linking it to how far we have the village: the urban landscape, and rescue the collective memory of people: the Landscape of Memory. These people had a closer and intimate relationship with the village, and kept in their unconscious vivid images of a past that continues to come to the surface and become a rich source of Cultural Heritage. This not only belongs to this group, but to all people, direct or indirectly, that are related to daily - the goiana society. We identified the strong and fixed elements that mark these landscapes and turn a local in a place, which show people the real feeling and topofilia. We also worked around the concepts of landscape, place, topofilia and memory in order to raise subsidies for a new approach on what constitutes the cultural heritage in Ouro Fino.
Esse estudo visa trabalhar as três paisagens existentes no Arraial de Ouro Fino − que se originou com o ciclo da mineração em Goiás, em meados do século XVIII, e ruiu no final da metade do século XX. Observando a Paisagem Arqueológica, relacionando-a com a Paisagem da Memória (a memória coletiva) para então resgatar a Paisagem Urbana (o que já foi do arraial). Trabalhar a memória coletiva das pessoas que mantiveram com o arraial um relacionamento mais estreito e íntimo, e guardaram em seus inconscientes imagens vívidas de um passado que persiste em vir à tona, sempre que evocado, e se transformar em fonte rica de Patrimônio Cultural. Este não pertence somente a este grupo, mas a todas as pessoas que, de forma direta ou indireta, relacionam-se cotidianamente a sociedade goiana. Foram identificados os elementos fixos e fortes que marcam essas paisagens e transformam um local em Lugar, que denotam às pessoas o verdadeiro sentimento e Topofilia. Trabalhou-se também em torno dos conceitos de Paisagem, Lugar, Topofilia e Memória, a fim de angariar subsídios para uma nova abordagem sobre o que se constitui o Patrimônio Cultural de Ouro Fino.

O método de decoração metálica com ouro, desenvolvido por Bassett, em 1958, é de muito interesse no estudo de cristais por microscopia eletrônica de transmissão. Desde aquela época, o método vem sendo aplicado ao estudo de vários fenômenos físicos relacionados à nucleação e epitaxia de filmes finos, bem como em estudos de crescimento e evaporação de cristais. Neste trabalho o método de réplica de decoração foi utilizado para investigar a microtopografia superficial de cristais inorgânicos, de interesse tecnológico e industrial. Nos vários experimentos de decoração, obtivemos adsorção bem localizada dos núcleos de ouro, ao longo de orientações definidas. Nos argilominerais caulinita e diquita, foram marcadas figuras poligonais que seguem os contemos pseudo-hexagonais da própria partícula cristalina. Nos cristais iônicos usados, brometo de potássio e cloreto de sódio, observaram-se degraus monoatômicos em formas variadas, inclusive em espirais originadas por discordâncias em parafuso. Outros sítios da superfície com diferentes energias de adsorção puderam ser identificados em todas as amostras estudadas, através desta metodologia. Nos cristais de calcita não logramos obter figuras de decoração bem definidas, mas sim áreas alternadas com ouro condensado e áreas de interdição, causadas provavelmente pela hidratação natural do mineral. Defeitos pontuais como vacâncias, ilhas ou depressões monoatômicas foram reconhecidos nas figuras de decoração, assim como degraus lineares causados por clivagem.The gold decoration method originally developed by Bassett in 1958, still is of great interest for unraveling microtopographic details of crystal surfaces in the transmission electron microscope. It is of interest also for studies relating to nucleation and epitaxial growth of thin films, as well as in the study of crystal growth and evaporation itself. The present study was intended to investigate the surface morphologies and defects of some selected inorganic crystals, having technological applications. Ali the different samples prepared by this replica method, presented a clear localization of the gold clusters, along very specific sites. The clay minerais kaolinite and dickite exhibited polygonal figures with a pseudo hexagonal arrangement, parallel to the crystal\'s edges. Growth steps having two different spacings were seen to interlace at 120°. Bromine and sodium halides have monoatomic steps aligned along linear or curved paths; these gold decorated steps could be followed for ample extents in the replicas; among them, other less usual patterns of gold decorated imperfections forming loops, waves and circles were located. The only exception was represented by calcite, in which the decoration was at random. Despite this, some images of deep steps caused by cleavage of the crystals could be clearly recognized. Control images obtained by scanning electron microscopy of cleaved crystals and direct transmission electron microscopy of clay mineral particles, were helpful in the interpretation of the results.

Previous issue date: 2013-06-27Neste trabalho um modelo analítico com base na teoria da elasticidade proposto para mensurar as tensões residuais em materiais ortotrópicosn foi descrito e aplicado para avaliar o coeficiente de Poisson em filmes finos de ouro. Os matérias metálicos geralmente possuem anisotropia e textura cristalográfica, o que gera problemas para se analisar as tensões via difração de raios X, uma vez que, as curvas de ε vs sen² Ψ tornam-se não lineares. Aplicando as simetrias referentes a ortotropia do material no tensor elasticidade, obtêve-se as relações tensão deformação para materiais ortotrópicos, as equações para as deformações foram encontradas em função do estado de tensões principais triaxial e biaxial para o caso onde as deformações são calculadas via XRD. Uma nova equação foi proposta para o coeficiente de Poisson fora do plano para o caso de filmes finos transversalmente isotrópicos. Um estudo de caso foi realizado aplicando-se as equações à dados experimentais obtidos na literatura para um filme fino de ouro com textura de fibra {111}, assim o valor do coeficiente de Poisson fora do plano pôde ser calculado de duas formas. A primeira foi realizada ajustando os dados experimentais pelo método dos mínimos quadrados. Na segunda o coeficiente de Poisson foi calculado como um valor médio de uma superfície que foi construida para o coeficiente de Poisson for a do plano como função de sen² Ψ e ε.

The present research had the objective of characterizing and analyzing the quality of rural environmental sanitation in the organic producing properties in the municipality of Ouro Fino, through a survey on environmental issues in the properties with emphasis on: water, soil, solid waste management and sanitation, in order to minimize the knowledge gap on rural environmental sanitation in areas of organic production. To collect data, a qualitative approach was used through semi-structured interviews with seven farmers, which made it possible to understand farmers' perceptions regarding various health, environmental and social aspects. The interviews were composed of thematic blocks: history of the property, profile of the owner, characteristics of the area surrounding the home, environmental sanitation, associativism and environmental perception. The data were analyzed and discussed in a descriptive way based on previous studies and quotations on the subject, as well as excerpts from the producers' statements. The data infer that the fact of being organic producers did not configure as a determinant aspect so that the conditions of the sanitation in their properties were presented ideal, unlike the environmental perceptions. Note the importance of the research that portrays the perception of individuals, whose results reproduce the real needs and desires of the population in question, in the search for more efficient and structured public policies in the rural area.
A presente pesquisa teve como objetivo central caracterizar e analisar a qualidade do saneamento ambiental rural nas propriedades produtoras de orgânicos no município de Ouro Fino, por meio de um levantamento sobre questões ambientais nas propriedades com ênfase em: água, solo, gestão de resíduos sólidos e esgotamento sanitário, com o intuito de minimizar a lacuna de conhecimento sobre o saneamento ambiental rural em áreas de produção de orgânicos. Para a coleta de dados utilizou-se de abordagem qualitativa através da realização de entrevistas semiestruturadas com sete agricultores, as quais possibilitaram compreender as percepções dos produtores em relação a vários aspectos sanitários, ambientais e sociais. As entrevistas foram compostas por blocos temáticos: história da propriedade, perfil do proprietário, características da área circundante ao domicílio, saneamento ambiental, associativismo e percepção ambiental. Os dados foram analisados e discutidos de maneira descritiva baseados em estudos anteriores e citações sobre o assunto, como também trechos das falas dos produtores. Os dados inferem que o fato de serem produtores orgânicos não configurou como aspecto determinante para que as condições do saneamento em suas propriedades se apresentassem ideais, diferentemente das percepções ambientais. Nota-se a importância da pesquisa que retrata a percepção dos indivíduos, cujos resultados reproduzem as verdadeiras necessidades e anseios da população em questão, na busca de políticas públicas mais eficientes e estruturadas na área rural.

AbstractVarious properties of the universe have been suggested as indicative of the work of ‘a designer’. I focus on two such properties: ‘fine-tuning’ and ‘the existence of orderly patterns of events which can be described by advanced mathematics’. While various forms of design inference have been suggested, for example, analogical, Bayesian, likelihoodist, and abductive, sceptics such as Roger Penrose objected that there could be alternative explanations which we still do not know of, while appealing to God can be used to solve any problem, so it is not helpful. This concern can be addressed by devising an original deductive argument which demonstrates that the following are the only possible categories of hypotheses—(i) Chance, (ii) Regularity, (iii) Combinations of Regularity and Chance, (iv) Uncaused, and (v) Design, and excluding all the alternative categories such that the conclusion of design follows logically (rather than being appealed to solve a problem). In response to the worry that previously unconsidered hypotheses could be lumped together in catch-all baskets, I show that there is an essential feature of each category (except design) which renders it unlikely as an explanation for the fine-tuning and order, beginning with (i)–(iii) and engaging with the multiverse hypothesis and Smolin’s evolutionary hypothesis.

Mineral deposits are found in almost every environment on Earth—from the ocean floor, to high mountains, deserts and jungles. What factors control the distribution of minerals across our planet, and why do we mine in environmentally sensitive areas? This chapter describes the unique processes—asteroids, anoxic ocean waters, volcanoes and salty seas—that have led to the accumulation of large metal deposits on Earth over millions or even billions of years. By understanding these processes, we can better appreciate why particular types of mineral deposits occur where they do, and how mineral exploration might change in the future.

The purpose of this study is to illustrate a method for obtaining the thermal performance and optimum dimensions of arrays consisting of rectangular longitudinal fins, cylindrical and elliptical cross-section spines. Since the majority of fin problems in an array have constant boundary temperatures, our endeavor is focused on the analysis and optimization of these types of fins. The temperature distribution, heat released to the environment, and the fins’ optimum dimensions in the array have been determined. Our analysis is based on a new set of dimensionless parameters, which are more suitable than those frequently used in fin analyses in the available literature. The effects of the boundary temperature ratio on the temperature variation in the fin have been examined and the results are shown graphically. Three salient results are derived regarding the thermal characteristics of these types of fins. They are: (1) the fin’s heat dissipation is expressed exactly with the same expression which describes the optimum heat dissipated by a fin with insulated tip, having half the fin’s dimensionless height. (2) The optimum fins’ dimensionless height and thickness are identical with those obtained for a fin with adiabatic tip of twice the dimensionless height (3) The optimum semi-axes ratio of elliptical-cross section spines is uniquely defined. In addition, it is shown that this approach can be successfully applied to solve problems in several practical applications, including pin fins having elliptic-cross sections. Two examples serve to illustrate the usefulness of our method.

Saturated pool boiling on vertically oriented, copper, wavy-fin surfaces in water at reduced pressures is investigated. A lamination of fine-filament, wire mesh is an effective surface enhancement for boiling since the surface can be configured to provide a very high density of potential bubble nucleation sites. Two surfaces are considered: a 0.75mm thick 4-layer laminate with approximately 4000 pores per cm2 and a 0.42mm thick 8-layer laminate with approximately 26,000 pores per cm2. The results show that the 8-layer laminate outperforms the 4-layer laminate. At reduced pressures a reduction in performance is seen for both surfaces. A semi-empirical boiling model is developed. The model predicts the boiling performance of our data within an error of 30%. The model shows that shorter fins improve boiling performance.

This paper investigates the relevance of business saving for private saving and investment around the world by constructing and exploiting a broad international, unbalanced panel of 64 countries over 1990-2012. The paper shows that businesses are the main contributors to private and national saving around the globe, contributing on average more than 50 percent of national saving. Using this unique dataset, evidence is found of partial piercing of the corporate veil: for the core estimation, it is found find that a $1 increase in business saving gives rise to a decrease of only $0. 28 in household saving. The non-neutrality of business saving is further confirmed by results showing that higher business saving is significantly associated with higher business investment. In conjuction with the empirical results, this paper sheds new light on the role of business saving in the economy by critically scrutinizing the existing macroeoconomic and corporate finance literatures.

In this project, we are determining the contribution of different types of variations, in gene function and in gene regulation, to altered shoot architecture first, and to field performance in the next stage. We are using tomato as a target, but also as a model for many other crops. Our focus is on two different components of yield associated traits - shoot architecture and organization of the inflorescence. Our focus was on two types of regulators; 1) genes involved in florigen - antiflogen balance and the way they impact the shoot, and 2) genes involved in inflorescence branching and it this way, the way they impact the number of flowers produced by the plant. For the first class, we described our thoughts on that matter in a joint review (Eshed and Lippman, 2019) where we argued that annualization of short-lived vine plants such as tomato and soybean was their major adaptation for intensive modern farming. This annualization was achieved by introduction of mutations in the anti florigen gene SELFPRUNING, mutations that were also used to domesticate/adapt cotton, roses, strawberries and more (Eshed and Lippman, 2019). Indeed, introduction of this mutation and additional one in another antifloraigen gene SP5G into a vine type tomatoes resulted in compact, early yielding plants suitable for urban agriculture (Kwon et al., 2020 - please note that Yossi Capua, a former graduate student from the Eshed group is a coauthor of this study). The other side of this project, customized generation of large branched inflorescences, relied on ongoing collaboration between the two labs on genes like S and genes of the SEP clade, J2 and EJ2. We first showed that highly branched j2 ej2 inflorescences can be quantitatively modified by introduction of either null or naturally weak alleles of the TM3/STM3 gene cluster (Alonge et al., 2020). We next showed that variation in inflorescence branching can be obtained by customized interreference in selected promoter motifs of S, a gene that is otherwise essential at the seed stage (Hendelamn et al., 2021). Overall, our joint project provided some prime examples for targeted use of genome editing for the formation of valuable alleles that can either improve modern crops or, significantly, open the door for rapid "domestication" of orphan crops

Our unequal global food system is unsustainable for people and planet. We urgently need to rethink how the world feeds its people. The food crisis we are facing is not new. Extreme inequality and poverty, rights abuses, conflict, climate change and inflation – exacerbated by the pandemic and the war in Ukraine – mean that hundreds of millions of people do not have enough to eat. While millions of people are struggling to find their next meal, the world’s main food traders have made record profits, adding billions to their collective wealth. This paper debunks 10 myths about our food system and provides an alternative framing that will lead to better outcomes for the long term. We must shift our current food system from an industrial, exploitative and extractive model to a local and sustainable one that contributes to climate resilience and realizes people’s right to food – one that reduces inequality and poverty.

Abstract. Tomato yellow leaf curl virus (TYLCV), a monopartitebegomovirus, is one of the most devastating viruses of cultivated tomatoes and poses increasing threat to tomato production worldwide. Because all accessions of the cultivated tomato are susceptible to these viruses, wild tomato species have become a valuable resource of resistance genes. QTL controlling resistance to TYLCV and other begomoviruses (Ty loci) were introgressed from several wild tomato species and mapped to the tomato genome. Additionally, a non-isogenic F₁diallel study demonstrated that several of these resistance sources may interact with each other, and in some cases generate hybrid plants displaying lower symptoms and higher fruit yield compared to their parental lines, while their respective resistance genes are not necessarily allelic. This suggests that pyramiding genes originating from different resistance sources can be effective in obtaining lines and cultivars which are highly resistant to begomoviruses. Molecular tools needed to test this hypothesis have been developed by our labs and can thus significantly improve our understanding of the mechanisms of begomovirus resistance and how to efficiently exploit them to develop wider and more durable resistance. Five non-allelic Ty loci with relatively major effects have been mapped to the tomato genome using molecular DNA markers, thereby establishing tools for efficient marker assisted selection, pyramiding of multiple genes, and map based gene cloning: Ty-1, Ty-2, Ty-3, Ty-4, and ty-5. This research focused on Ty-3 and Ty-4 due to their broad range of resistance to different begomoviruses, including ToMoV, and on ty-5 due to its exceptionally high level of resistance to TYLCV and other begomoviruses. Our aims were: (1) clone Ty-3, and fine map Ty-4 and Ty-5 genes, (2)introgress each gene into two backgroundsand develop semi isogenic lines harboring all possible combinations of the three genes while minimizing linkage-drag, (3) test the resulting lines, and F₁ hybrids made with them, for symptom severity and yield components, and (4) identify and functionally characterize candidate genes that map to chromosomal segments which harbor the resistance loci. During the course of this research we have: (1) found that the allelic Ty-1 and Ty-3 represent two alternative alleles of the gene coding DFDGD-RDRP; (2) found that ty-5is highly likely encoded by the messenger RNA surveillance factor PELOTA (validation is at progress with positive results); (3) continued the map-based cloning of Ty-4; (4) generated all possible gene combinations among Ty-1, Ty-3 and ty-5, including their F₁ counterparts, and tested them for TYLCV and ToMoV resistance; (5) found that the symptomless line TY172, carrying ty-5, also carries a novel allele of Ty-1 (termed Ty-1ⱽ). The main scientific and agricultural implications of this research are as follows: (1) We have developed recombination free DNA markers that will substantially facilitate the introgression of Ty-1, Ty-3 and ty-5 as well as their combinations; (2) We have identified the genes controlling TYLCV resistance at the Ty-1/Ty-3 and ty-5 loci, thus enabling an in-depth analyses of the mechanisms that facilitate begomovirus resistance; (3) Pyramiding of Ty resistance loci is highly effective in providing significantly higher TYLCV resistance.

Over the last two years, the Esade Center for Social Impact, which is part of Esade Business School in Spain, and its partner BBK, a banking foundation in Bilbao, have been at the center of a web of committed European foundation professionals sharing their thoughts, learnings, practices, frustrations, and eureka moments related to impact measurement and management (IMM). This paper is not a practical guide to Impact Measurement and Management (IMM) – we believe that there are other publications which may help with implementation. Rather, it recounts how foundations at different stages of development and with a range of profiles (corporate, family, operating, and grant-making) are going about IMM on a day-to-day basis and grappling with some of the challenges and philosophical issues arising. For the impact geeks, this will no doubt be interesting grist for the mill. For those not so deep into this space, it might provide an overview of where foundations are in Europe and how they are focusing their efforts on IMM. Our aim is that by synthesizing and sharing what we have heard in this safe space we can inform and inspire others.

Using unique firm-level data, we analyze the characteristics of services exporters in one of world's most important services traders: Spain. Our paper shows that only a small percentage of firms participate in services export; moreover, exports represent a small share of total turnover for traders. We also find that exporters have a premium over non-exporters in size, sales, labor productivity and differentiation level. These variables also play an important role in determining firms' participation in the export market and in firms' export intensity. Our results show that exporters where already more productive than other firms before starting to export. We do not find evidence that exporting increases firms' productivity.

Velocity field in the McMurdo shear zone from annual ground penetrating radar imaging and crevasse matching. Engineer Research and Development Center (U.S.), grudzień 2021. http://dx.doi.org/10.21079/11681/42623.
Pełny tekst źródłaStreszczenie:
The McMurdo shear zone (MSZ) is strip of heavily crevassed ice oriented in the south-north direction and moving northward. Previous airborne surveys revealed a chaotic crevasse structure superimposed on a set of expected crevasse orientations at 45 degrees to the south-north flow (due to shear stress mechanisms). The dynamics that produced this chaotic structure are poorly understood. Our purpose is to present our field methodology and provide field data that will enable validation of models of the MSZ evolution, and here, we present a method for deriving a local velocity field from ground penetrating radar (GPR) data towards that end. Maps of near-surface crevasses were derived from two annual GPR surveys of a 28 km² region of the MSZ using Eulerian sampling. Our robot-towed and GPS navigated GPR enabled a dense survey grid, with transects of the shear zone at 50 m spacing. Each survey comprised multiple crossings of long (> 1 km) crevasses that appear in echelon on the western and eastern boundaries of the shear zone, as well as two or more crossings of shorter crevasses in the more chaotic zone between the western and eastern boundaries. From these maps, we derived a local velocity field based on the year-to-year movement of the same crevasses. Our velocity field varies significantly from fields previously established using remote sensing and provides more detail than one concurrently derived from a 29-station GPS network. Rather than a simple velocity gradient expected for crevasses oriented approximately 45 degrees to flow direction, we find constant velocity contours oriented diagonally across the shear zone with a wavy fine structure. Although our survey is based on near-surface crevasses, similar crevassing found in marine ice at 160 m depth leads us to conclude that this surface velocity field may hold through the body of meteoric and marine ice. Our success with robot-towed GPR with GPS navigation suggests we may greatly increase our survey areas.

Pełny tekst źródłaStreszczenie:
This paper analyzes empirically the relationship between innovation and productivity in the Chilean services sector. Consistent with recent evidence on developed countries, we find that services firms are as innovative as firms in the manufacturing industry. In the basic model, we also find that both industries have similar determinants of the investment in innovation and the probability of introducing innovations (products or process), such as size and export status. In several extensions we find similar roles for technological and non-technological innovation in labor productivity and for determinants such as skill intensity and financial restrictions. In general, our evidence suggests that that innovation input and output is associated with improvements in productivity in both sectors. Since we do not find clear-cut differences, it might be the case that even larger efforts need to be done to have better measures of innovation and productivity in the services industries.

Pełny tekst źródłaStreszczenie:
This paper explores how stagnating real wages may have contributed to the slowdown of US productivity. Through shift-share analysis, we find that after a sharp change in distribution against wages, some historically high-productivity sectors (like manufacturing) switched towards slower productivity growth. This supports our hypothesis that the anemic growth of productivity may be partly due to the trend toward massive use of cheap labor. Our estimation of Sylos Labini’s productivity equation confirms the existence of two direct effects of wages, one acting through the incentive to mechanization and the other through the incentive to reorganize labor use. We also show that labor ‘weakness’ may exert a further negative effect on labor productivity. On the whole, we find that a persistent regime of low wages may determine very negative long-term consequences on the economy.
