Abate humanitário de crocodilianos.

Para a implantação da prática de abate humanitário para os jacarés foi desenvolvida pela Gil Equipamentos e a Embrapa Pantanal, a pistola ZILKA (Fig.1). A pistola foi desenvolvida para atender uma solicitação de pesquisa da Embrapa Pantanal a durante a execução do projeto de manejo experimental do jacaré-do-pantanal, Caiman crocodilus yacare, no Pantanal Sul. A pistola causa respostas de sensibilidade nos jacarés com um rápido estado de inconsciência e a incapacidade de respostas a estímulos externos. Essa etapa é fundamental para garantir o abate dentro dos princípios humanitários, uma vez que garantirá a inconsciência dos jacarés até a sangria. A pistola ZILKA também pode ser usada para abate de outros animais criados em cativeiro (ovinos e caprinos) ou animais oriundos de manejo na natureza.bitstream/item/37477/1/CT59.pd

Diversidade de Scarabaeoidea (Insecta: Coleoptera) coletados com armadilha de interceptação de voo no Distrito Federal.

Os representantes da superfamília Scarabaeoidea formam um grupo diverso de organismos que apresentam diferentes hábitos alimentares e comportamento. Esses insetos são normalmente coletados utilizando-se armadilhas de queda ou armadilha luminosa. Entretanto, o uso de armadilha de interceptação de voo pode revelar diferenças na diversidade em Scarabaeoidea, principalmente no Distrito Federal, onde o seu uso é pouco comum. O objetivo desse trabalho foi avaliar a diversidade (riqueza e abundância) de Scarabaeoidea coletados com armadilha de interceptação de voo no Distrito Federal. O estudo foi conduzido em uma área de Cerrado (cerradão) (Planaltina/DF) onde foi instalada uma armadilha de interceptação de voo, composta por uma tela de sombrite preto (1 x 2 m), esticada em posição perpendicular ao solo deixando-se um espaço de ≈10 cm em relação ao solo onde foram encaixadas cinco bandejas plásticas contendo água e detergente. Semanalmente, entre outubro/2013 e abril/2014, os Scarabaeoidea foram coletados e identificados em nível de gênero. Foram coletados 504 espécimes de Scarabaeoidea pertencentes a 3 famílias (Scarabaeidae, Melolonthidae e Geotrupidae) e 24 gêneros (Anomiopus, Anthicheira, Ataenius, Athyreus, Bolbapium, Canthidium, Canthon, Coprophanaeus, Deltochillum, Dendropaemon, Dichotomius, Eurysternus, Eutrichillum, Isonychus, Leucothyreus, Lobogeniates, Lyogenis, Neoathyreus, Ontherus, Oxysternon, Paranomala, Phyllophaga, Plectris e Trizogeniates). Coprophanaeus (n=85) e Oxysternon (n=80) foram os gêneros mais abundantes e juntamente com Deltochillum, Neoathyreus, Eurysternus, Eutrichillum e Dichotomius representaram 84,3% do total coletado. A família Scarabaeidae apresentou maior abundância (n=410) e riqueza (12 gêneros). A maior abundância de Scarabaeoidea foi observada entre novembro e dezembro/2013 (68,8% do total coletado). A armadilha de interceptação de voo se mostrou adequada para coleta de Scarabaeoidea revelando alta diversidade coletada

3-Aminopyrroles and their application in the synthesis ofpyrrolo[3,2-d]pyrimidine (9-deazapurine) derivatives

3-Aminopyrrole derivatives have been synthesized from 3-anilino-2-cyanoacrylonitrile using Thorpe-Ziegler cyclization. These substituted pyrroles are readily converted into 5H-pyrrolo[3,2- d]pyrimidine (9-deazapurines).FEDERFundação para a Ciência e Tecnologia (FCT

Heterocyclic synthesis with nitriles: synthesis of pyridazine and pyridopyridazine derivatives

The reaction of MND with aryldiazonium chlorides followed by cyclization afforded the pyridazinimine derivatives. Reaction of the latter with another mole of malononitrile produce only pyrido[3,2-c]pyridazine derivatives. Reaction of 4-aminopyridazinone-3- carboxylic acid esters with malononitrile gave only pyridazine-3-carboxylic acid.Fundação para a Ciência e a Tecnologia (FCT) - POCTI-SFA-3-686, SFRH/BPD/31490/2006Fundo Europeu de Desenvolvimento Regional (FEDER

Synthesis of some novel pyrazolo[3,4-d]pyrimidine derivatives

Reaction of ethyl imidates derived from N-aryl-5-amino-4-cyanopyrazoles with amines or arylhydrazines gave only 4-substituted pyrazolo[3,4-d]pyrimidines, resulting from cyclization followed by Dimroth rearrangement. From the reaction with arylhydrazines, a mixture of the hydrazines and their oxidized forms, the azo products, was obtained. This was proven by an independent synthesis starting from the corresponding 4-chloropyrazolo[3,4-d]pyrimidines as starting material. The structures of the compounds obtained were confirmed by mass spectrometry, 1H and 13C NMR.Fundação para a Ciência e Tecnologia (FCT) - POCTI-SFA-3-686, SFRH/BPD/31490/2006FEDE

THE IMPACT OF VOLUNTEERING AND THE ACQUISITION OF SKILLS THROUGH PRACTICE

This study intended to assess the impact of volunteering on society and understand how its practice allows the acquisition of skills. In addition, it would make the population aware of the value and importance of the different ways of volunteering. One of the central points of this investigation was to understand how institutions should recruit and attract volunteers and ultimately how to retain them, by understanding whether or not the volunteers’ initial motivations (i.e. which attract them) remain unchanged along time. This study was carried out within the scope of the ENtRANCE Erasmus+ project, by students of the Research Methods and Techniques course integrated in the Communication Sciences degree at Maia University Institute and had the collaboration of the Volunteer School, Pista Mágica by contacting its volunteers and clarifying relevant information. Several scientific articles were analysed, such as [1]; [2]; [3]; [4]; [5] which allowed a first approach to such topic but with no answers found.info:eu-repo/semantics/publishedVersio

Thermal analysis of a polymorphic azo dye derived from 2-amino-5-nitrothiazole

An azo dye, derived from 2-amino-5-nitrothiazole and a substituted N,N-dimethyl aniline, was studied by various techniques. Two sets of proton signals were obtained by NMR in CDCl3 solution, suggesting that two polymorphs coexist, however only one set of signals is observed in DMSO solution. Differential scanning calorimetry and thermogravimetric analysis were used to confirm the existence of two forms. The events registered during thermal treatment of a sample were assigned to a glass transition, recrystallization and fusion of crystalline compounds. Hot-stage microscopy was used to obtain images of the dye samples at various stages of the heating program and these observations support the interpretation of the calorimetric results.Fundação para a Ciência e a Tecnologia (FCT

Synthesis of 5H-pyrido[4,3-b]indole by a modification of Pomeranz-Fritsch isoquinoline synthesis.

5H-Pyrido[4,3-b]indole was obtained from 3-formylindole in 16% overall yield by Jackson and Shannon modification of the Pomeranz-Fristch isoquinoline synthesis. The final cyclisation occurred but the removal of the tosyl group and oxidation of the dihydrocompound was not efficient. Changes in the concentration of the acid catalyst gave 29% as the best yield for the last step. An NMR study of the cyclisation is described.Fundação para a Ciência e Tecnologia (FCT) and FEDE
