A Biosensor for Detection of DNA Sequences Based on a 50MHz QCM electronic oscillator circuit ArchiMer
Bustabad, E. A.; Garcia, G; Rodriguez-pardo, L.; Farina, J.; Perrot, H.; Gabrielli, C.; Bucur, B.; Lazerges, M.; Rose, D.; Compere, Chantal; Arnau, A..
This work deals with the development of a high sensibility DNA biosensor based on a 50MHz Quartz Crystal Microbalance (QCM) Oscillator Electronic Circuit. The designed QCM oscillator sensor is able to detect the presence of complementary DNAs in a solution that match the sequence on a given strand in function of the changes in the output frequency of the oscillator. The design is adapted so that the Barkhausen condition is satisfied even when the quartz is immerged in liquid media. Also a comparative study of the developed 50MHz biosensor in front of a QCM oscillator with smaller frequency is carried out, with object of checking if the sensibility of the oscillator increases, allowing to detect smaller concentrations of the complementary DNA.

A bioüzemanyagok használatával járó várható földhasználati változások Magyarországon AgEcon
Vida, Adrienn; Baksa, Adrienn.
Az egyre növekvő energiafelhasználás, világnépesség és éhezés olyan, több évtizede megoldatlan problémák, amelyeket a klímaváltozás és az ez által kialakult szélsőséges időjárási viszonyok tovább súlyosbítottak, a napjainkban tapasztalható gazdasági válság pedig még inkább megnehezítheti megoldásukat. A megújítható energiaforrások szerepének növelésében katalizátorszerepet betöltő Európai Unió már a 80-as évek elején megoldást keresett a túltermelés következtében felhalmozódott szántóföldi termékek felhasználására. Az idők során a támogatási rendszer is a non-food termelést helyezte egyre inkább előtérbe, majd a kialakított direktívák és piaci intézkedések előkészítették, és így biztosították az összefoglalóan biomasszának nevezett megújítható...

A Blueprint for Reform of the WTO Agreement on Agriculture AgEcon
Zahrnt, Valentin.
As the Doha negotiations are at a dead end, this paper takes a step back to address the future direction of WTO disciplines in agriculture. It puts members’ negotiating positions and the draft modalities with their ever growing list of exceptions aside to focus on three fundamental questions. First, which agricultural policy instruments should be permitted or prohibited by WTO disciplines so as to best account for the manifold effects of agriculture on societies’ welfare? Second, how should inefficient agricultural policies be treated as long as their removal is politically infeasible? And third, how can the WTO facilitate agricultural policy reform beyond establishing maximum thresholds for distorting policies? The paper argues for moving from the current...

A BOA convivência entre a agricultura e a fauna silvestre - programa 44. Infoteca-e
Há mais de 20 anos, a Embrapa Monitoramento por Satélite (Campinas/SP) desenvolve métodos para avaliação da biodiversidade em propriedades rurais, com ênfase na fauna selvagem. São estudos aplicados em diversos tipos de propriedades rurais e em vários ecossistemas, que identificaram centenas de espécies de vertebrados selvagens, de alguma forma, relacionados às áreas agrícolas. O pesquisador José Roberto Miranda explica que a busca pela conservação da biodiversidade animal (variedade de espécies) tem se concentrado mais em ações para preservação de ecossistemas naturais. "Pouca atenção se dá ao papel das áreas agrícolas e dos processos produtivos na manutenção da biodiversidade animal. A presença da fauna selvagem em áreas agrícolas é pouco estudada e...

A bortermelés struktúrájának változásai AgEcon
Brazsil, David.
A szőlő-bor vertikum termelési oldalán jelentős koncentrációs folyamatok kez¬dődtek. A koncentráció egyik motorja a befektetők, akik az 1980-as évektől jelentek meg nagy számban az ágazatban. Stratégiájukat alapvetően az alapanyaghoz való hozzáférés, a terjeszkedési lehetőség, a márkaépítés és a disztribúciós csatornákhoz való hozzáférés határozza meg. Magyarországon a koncentrációs folyamatokat a jogi-gazdasági környezet erősen befolyásolta. ------------------------------------- Significant concentration processes have begun in the production side of the grape and wine business. These are in part driven by the investors who appeared in large numbers in this field after the eighties. Their strategy is basically determined by their access to raw...

A bovine teat papilloma specimen harboring Deltapapillomavirus (BPV-1) and Xipapillomavirus (BPV-6) representatives BABT
Claus,Marlise Pompeo; Lunardi,Michele; Alfieri,Amauri Alcindo; Otonel,Rodrigo Alejandro Arellano; Ferracin,Lara Munique; Fungaro,Maria Helena Pelegrinelli; Alfieri,Alice Fernandes.
The common occurrence of multiple papillomavirus infections has been shown in several studies involving the human host. However, investigations with the aim of identifying mixed papillomavirus infections in cattle have been conducted only recently. In the current work we describe a co-infection with two different bovine papillomavirus (BPV) types that was identified in a bovine teat papilloma. The skin wart was obtained from a cow belonging to a Brazilian beef herd. A PCR assay was carried out with the FAP primer pair, which amplifies a partial segment of the L1 gene (approximately 478 bp), and the amplicon was submitted to direct sequencing. Because nucleotide sequences with satisfactory quality scores were not obtained, the amplicon was cloned and...

A broca do fruto do abacaxi Strymon megarus no Estado do Pará. Repositório Alice
NORONHA, A. C. da S.; SILVA, T. de A.; TAVARES, G. dos S.; KRAMER, V. R.; MATOS, A. P. de..
A broca-do-fruto Strymon megarus (Godart, 1824) (Lepidoptera, Lycaenidae) é considerada uma das principais pragas da abacaxicultura, podendo causar prejuízos de até 80% quando não controlada (SANCHES, 2005). Os sintomas do ataque da praga são evidentes com a exsudação de resina incolor e fluída nos frutos e eventualmente pode atacar as coroas dos frutos, gemas e mudas na base das inflorescências e raramente minando folhas de abacaxi (MATOS et al.,2007). No município de Floresta do Araguaia, no Sudeste Paraense, S. megarus se constitui em um dos principais problemas fitossanitários do abacaxizeiro Ananas comosus var.comosus L. Merril. juntamente com a podridão-do-olho Phytophthora nicotinae var.parasitica e a fusariose Fusarium subglutinans f. sp. ananas....

A bumblefoot outbreak and fatal septicemia in captive aquatic birds in Brazil Ciência Rural
Marques,Marcus Vinícius Romero; Resende,José Sérgio de; Donatti,Rogério Venâncio; Vilela,Daniel Ambrózio da Rocha; Ecco,Roselene; Martins,Nelson Rodrigo da Silva.
A bumblefoot outbreak with different prognosis according to host species was studied in captive aquatic avian species. Six wood ducks (Aix sponsa), three scarlet-ibis (Eudocimus ruber), two black-swans (Cygnus atratus), five white-faced ducks (Dendrocygna viduata) and two roseate spoonbills (Platalea ajaja) were kept in a common pen with abrasive pavement pond margin, predisposing to podal skin wear. Incoordination and mortality occurred in the two roseate spoonbils and one black swan. Coagulase-positive penicillin-resistant Staphylococcus aureus was isolated from the synovial fluid and from the liver. All birds sharing the pen presented active or cicatricial foot lesions, indicating a possible challenge to the environmental Staphylococci. However, except...

A calibrated agricultural water demand model for three regions in northern Baja California Agrociencia
Medellín-Azuara,Josué; Howitt,Richard E.; Waller-Barrera,Cynthia; Mendoza-Espinosa,Leopoldo G.; Lund,Jay R.; Taylor,Joseph E..
Irrigated agriculture is the largest water user in many regions, and agricultural water use efficiency and consumption has been studied by several authors. This paper provides a framework and application of economic valuation of water for agriculture in three regions in northern Baja California, Mexico, namely Guadalupe, Maneadero and Mexicali Valleys. Positive mathematical programming (PMP), a deductive valuation technique, was the framework used for this estimation using water delivery data reported by the National Water Commission in Mexicali, production costs and cultivated area, production factors use from the Agriculture Ministry (SAGARPA); and other data from previous studies. Analysis of the results shows that marginal economic water value in...

A Case of Unusual Anatomy: Maxillary Central Incisor with Two Root Canals International Journal of Morphology
Rodrigues,Evaldo Almeida; Silva,Sílvio José Albergaria da.
Success in root canal treatment is achieved after thorough cleaning and shaping followed by complete obturation of the canal system. Therefore, endodontic therapy requires specific and complete knowledge of the internal and external dental anatomy, and its variations in presentation. Such treatment may be performed in root canal systems that do not comply with the normal anatomical features described in standard textbooks. The internal anatomy of the maxillary central incisor is well known and usually presents one root canal system. This case report describes an endodontic retreatment of a maxillary central incisor with two canal systems.

A Century of Synthetic Fertilizer: 1909-2009 Organic Eprints
Paull, John.
This year marks a centenary of the synthetic fertilizer industry. German chemists, Fritz Haber and Carl Bosch, in 1909 demonstrated their industrial process for the manufacture of ammonia. The achievement won them accolades including Nobel Prizes. The output of their Haber-Bosch process can be used for either peace or war, agriculture or munitions, and the rapid adoption by Germany of this industrial process is credited with prolonging WW1. Most of the synthetic nitrogenous fertilizer of the past century, and right up to the present, has been manufactured using the Haber-Bosch process. The use of synthetic fertilizers has led to significant negative environmental outcomes. Rudolf Steiner was an early voice against chemical agriculture. Steiner's...

A choice experiment method to assess vegetables producers’ preferences for crop insurance AgEcon
Mercade, Lluc; Gil, Jose Maria; Kallas, Zein; Serra, Jordi.
Agricultural producers face many risks in their economic activity due to weather conditions, plant or animal diseases, price volatility, policy changes and so on. One of the management tools to deal with some of these risks is the crop insurance system. In Catalonia (North-East of Spain) farmers’ participation in crop insurance for vegetables is low. Only 5 percent of the vegetables area is insured, when in Spain, as a whole, this percentage is around 20 percent. Different reasons have been suggested to explain this low participation ratio such as low risk perception, risk diversification, insurance cost or crop damage assessment rules, among others. However, no systematic research has been undertaken to assess farmers’ preferences for crop insurance in...

A Choice Modelling Survey of Community Attitudes to Improvements in Environmental Quality in NSW Catchments AgEcon
Mazur, Kasia; Bennett, Jeffrey W..
The survey was designed to estimate environmental values suitable for integration into MOSAIC, a bio-economic model for catchment and farm level planning. Local residents, as well as distant rural and distant urban communities, were surveyed in three NSW catchments (Lachlan, Namoi and Hawkesbury-Nepean) using choice modelling (CM). The survey aimed to find out respondents’ attitudes about, and preferences for, potential natural resource management (NRM) improvements. In total, 3,997 responses were collected from seven different locations in NSW. Fourteen split samples were established to allow for testing of incentive compatibility in CM, the impact of respondent location on values held, and scale effects. This research report describes the development...
