A catalogue of the type specimens of the family Buprestidae (Insecta: Coleóptera) housed at the "Museo of La Plata", Argentina Rev. Soc. Entomol. Argent.
LANTERI,Analía A; HERNÁNDEZ,Emilia P.
We provide information on the type specimens of Neotropical species of Buprestidae (Coleoptera: Buprestoidea) deposited at the Museo de La Plata (MLP). Among them, there are syntypes of 45 species of J. Obenberger, and syntypes, holotypes or paratypes of species described by C. Berg, A. Cobos and Ch. Kerremans, plus lectotypes and paralectotypes designated based on syntypes of Obenberger' species. Besides, we compiled a list of 37 species which specimens are labeled as types (metatypes or homotypes), but in fact these specimens were compared with the types by the authors of the species (e.g. C. Burmeister, J. Obenberger, Ch. Kerremans). Moreover, we provide information on missing types (formerly at the MLP but not in the collection at present) and...

A CFD approach to assess the effects of different opening combinations in poultry houses AGRIAMBI
Saraz,Jairo A. O.; Rocha,Keller S. O.; Damasceno,Flavio A.; Tinoco,Ilda F. F.; Osorio,Robinson; Tobón,Julio C. A..
ABSTRACT The aim of this study was to use computational fluids dynamics (CFD) to evaluate hygiene and comfort conditions in function of temperature level and ammonia (NH3) concentration during the night in commercial poultry houses used in Brazil and countries with tropical and subtropical climates. Four models with different curtain heights and different air inlet and outlet positions were used, adopting the open building typology without thermal insulation. The validated CFD model did not present statistical differences from the experimental data, making it possible to use this model to predict the behavior in the four proposed cases. This model can be used to improve the internal conditions of the poultry facilities during the night and could be an...

Abstract Background Envenomation caused by multiple stings from Africanized honeybees Apis mellifera constitutes a public health problem in the Americas. In 2015, the Brazilian Ministry of Health reported 13,597 accidents (incidence of seven cases per 100,000 inhabitants) with 39 deaths (lethality of 0.25%). The toxins present in the venom, which include melittin and phospholipase A2, cause lesions in diverse organs and systems that may be fatal. As there has been no specific treatment to date, management has been symptomatic and supportive only. Methods In order to evaluate the safety and neutralizing capacity of a new apilic antivenom, as well as to confirm its lowest effective dose, a clinical protocol was developed to be applied in a multicenter,...

A Comparative Analysis of Organic and Conventional Farming Profitability Organic Eprints
Brozova, Ivana.
The objective of this article is to determine the economic performance of organic farms compared with conventional farms. The analysis included a set of farms the concentration of which is in natural and climatic conditions typical for this type of farming high. The outputs may be therefore considered representative and generalised. In order to determine the performance of these farms, their production basis was first assessed by using the indicators of available assets and assets coverage resources. Consequently, their efficiency was assessed based on the profit. For the purposes of comparison, the profit was (in various forms) converted to a hectare of agricultural land. The economic results were also compared with the average level achieved in the EU....

A Comparative Study of Fixatives for Axolotl Blastema Tissue International Journal of Morphology
Keskin,Ilknur; Yildirim,Berna; Kolbasi,Bircan; Öztürk,Gürkan; Demircan,Turan.
Regeneration is defined as tissue renewal and functional restoration process of the damaged parts of the body after an injury. Ambystoma mexicanum, commonly named the Axolotl, is one of the unique vertebrates, which has a remarkable ability to regenerate their extremities following the amputation. Although the process of regeneration includes several periods, it can be divided into two main phases; blastema formation and dedifferentiation. In the couple of hours following the amputation, wound closure occurs by migration of epithelial cells around the amputation site followed by macrophage infiltration and dedifferentiation of cells to turn into stem cells. Accumulated stem cells form a very authentic tissue type called blastema, which is crucial for...

A comparative study of two separate analytical techniques for the simultaneous determination of diclofenac sodium and diacerein from combined dosage form BJPS
Mallick,Sanhita Basu; Chattopadhyay,Helen; De,Amit Kumar; Datta,Sriparna.
ABSTRACT Diclofenac sodium (DS) and diacerein (DC) have emerged as a potential combination therapy for the treatment of knee osteoarthritis. Therefore a validated analytical method is essential for the simultaneous estimation of both from combined dosage form. A ratio derivative spectrophotometric and a chromatographic technique have been developed for the simultaneous determination of DS and DC. The quantification was done at 263.00 nm for DC and 304.50 nm for DS in the first method, whereas 257 nm for DC and at 274 nm for DS for LC-DAD analysis in chromatographic method using acetate buffer and methanol as the mobile phase at a flow-rate 0.50 mL/min. Both of these methods are found to be linear in the concentration range under study with r2 value 0.999...

YANG,Dongmei; ZHANG,Qian; REN,Guoping; YING,Tiejin.
Abstract In this study, the antioxidant activities of different parts of lotus (Nelumbo nuficera Gaertn) rhizome were compared. The total phenolic content of lotus rhizome was determined, and Ferric reducing antioxidant power (FRAP) assay, 1,1-diphenyl-2-picrylhydrazyl hydrate (DPPH) radical-scavenging assay and β-carotene-linoleic acid assay were performed to assess the antioxidant activity of lotus rhizome. Results showed that there was a significant difference in total phenolic content and antioxidant activity between any two of four parts of lotus rhizome. The order of total phenolic content and antioxidant activity in different parts of lotus rhizome was as follows: peel of old lotus rhizome > peel of young lotus rhizome > flesh of old lotus...

A comparative study on drying of basil leaves CIGR Journal
Parmar, Mansukhlal Ramjibhai; Kumpavat, Mahendrasinh T.; Doshi, Jayesh Sevantilal; Kapdi, Shyamsundar S..
Basil is a popular aromatic and annual herb growing in many regions of the world.  Immediately after its harvesting, the highly perishable raw material, i.e. leaves, have to be preserved against deterioration and spoilage.  More often, during peak period, most of the crop is lost/wasted due to lack of proper post-harvest processing techniques.  Drying is by far the most widely used treatment, which needs to be performed very carefully and preciously so as to preserve the aroma and color of the leaves.  Various drying treatments and experimental methods viz., solar drying, tray drying, vacuum drying and fluidized bed drying were carried out at the temperatures of45°C,55°Cand65°Cto find and suggest the optimum drying condition for acquiring quality dried...

A comparison of tissue preparation methods for protein extraction of cocoa ( Theobroma cacao L.) pod Acta Agron. (Palmira)
Martínez-Márquez,Ascensión; Morante-Carriel,Jaime Alfredo; Bru-Martínez,Roque.
Abstract: Cocoa, Theobroma cacao L. is one of the main tropical industrial crops. Cocoa has a very high level of interfering substances, such as polysaccharides and phenolic compounds that could prevent the isolation of suitable protein. Efficient methods of protein extraction are a priority to successfully apply proteomic analyses. We compared and evaluated two methods (A and B) of tissue preparation for total protein extract by phenol/SDS extraction protocol. The difference in the application of the two methods was that extensively washed dry powder of pod tissue were made in Method A, whereas that crude extract were prepared Method B. Extracted proteins were examined using one-dimensional electrophoresis (1-D). Results show that each extraction method...

A comparison of two global datasets of extreme sea levels and resulting flood exposure ArchiMer
Muis, Sanne; Verlaan, Martin; Nicholls, Robert J.; Brown, Sally; Hinkel, Jochen; Lincke, Daniel; Vafeidis, Athanasios T.; Scussolini, Paolo; Winsemius, Hessel C.; Ward, Philip J..
Estimating the current risk of coastal flooding requires adequate information on extreme sea levels. For over a decade, the only global data available was the DINAS-COAST Extreme Sea Levels (DCESL) dataset, which applies a static approximation to estimate extreme sea levels. Recently, a dynamically derived dataset was developed: the Global Tide and Surge Reanalysis (GTSR) dataset. Here, we compare the two datasets. The differences between DCESL and GTSR are generally larger than the confidence intervals of GTSR. Compared to observed extremes, DCESL generally overestimates extremes with a mean bias of 0.6m. With a mean bias of -0.2m GTSR generally underestimates extremes, particularly in the tropics. The Dynamic Interactive Vulnerability Assessment model is...

A confiabilidade do PRODES: estimativa da acurácia do mapeamento do desmatamento no estado Mato Grosso. Repositório Alice
ADAMI, M.; GOMES, A. R.; BELUZZO, A.; COELHO, A. dos S.; VALERIANO, D. de M.; RAMOS, F. de S.; NARVAES, I. da S.; BROWN, I. F.; OLIVEIRA, I. D. de; SANTOS, L. B.; MAURANO, L. E. P.; WATRIN, O. dos S.; GRAÇA, P. M. L. de A..
PRODES is completing almost thirty years of uninterrupted monitoring of clear-cut deforestation over the Brazilian Amazon. Until now, no estimate of its mapping accuracy has been made. In this sense, this article brings a first approximation of mapping accuracy estimation of PRODES deforested areas, taking as example the state of Mato Grosso for the year 2014. For this, a random sampling panel was constructed, stratified with two strata, the deforestation of 2014 and the remaining forest. The sample size was calculated using the binomial function. In addition, a web platform was built to evaluate the points drawn by three independent evaluators. The global accuracy of the mapping of deforestation for the state of Mato Grosso, for the year 2014 was 94.5%,...

A contribuição dos agricultores familiares da região sul da Amazônia brasileira à crise ecológica global. Repositório Alice
ABREU, L. S. de; SANTOS, A. da S. dos; WATANABE, M. A..
Poucos estudos têm analisado o papel da população amazônica para a conservação ecológica da biodiversidade e para a redução dos efeitos da crise ecológica global. Esse estudo aborda experiências com Sistemas Agroflorestais (SAFs) desenvolvidas pela Associação de Agricultores Alternativos (APA), em Ouro Preto do Oeste - RO. O objetivo foi o de verificar se é possível conciliar a conservação ambiental com o desenvolvimento da agricultura familiar no sul da Amazônia. A hipótese é que a agrobiodiversidade associada aos Sistemas Agroflorestais contribui para a minimização da crise ambiental global. Essa afirmação se contrapõe ao velho diagnóstico de culpar os agricultores menos favorecidos economicamente pela destruição de florestas. O estudo documentou...

A cost-effectiveness analysis of alternative survey methods used for the monitoring of marine recreational fishing in France ArchiMer
Bellanger, Manuel; Levrel, Harold.
The growth of marine recreational activities raises the issues of the current lack of knowledge on these activities and the information required to assess their potential impacts. Indeed, the monitoring of unrecorded activities is a great challenge, especially when basic information, such as the size of the population practicing the different activities, is unknown. In this paper, the experience of the monitoring of marine recreational fishing was used to carry out a diagnosis study to assess the cost-effectiveness of survey methods used in France between 2004 and 2012. Costs of alternative surveys were balanced with data quality, and particular attention was paid to potential biases. Results showed that the involvement of citizens through diary surveys...

A coupled biophysical model for the distribution of the great scallop Pecten maximus in the English Channel ArchiMer
Le Goff, Clement; Lavaud, Romain; Cugier, Philippe; Jean, Fred; Flye-sainte-marie, Jonathan; Foucher, Eric; Desroy, Nicolas; Fifas, Spyros; Foveau, Aurelie.
In this paper we used a modelling approach integrating both physical and biological constraints to understand the biogeographical distribution of the great scallop Pecten maximus in the English Channel during its whole life cycle. A 3D bio-hydrodynamical model (ECO-MARS3D) providing environmental conditions was coupled to (i) a population dynamics model and (ii) an individual ecophysiological model (Dynamic Energy Budget model). We performed the coupling sequentially, which underlined the respective role of biological and physical factors in defining P. maximus distribution in the English Channel. Results show that larval dispersion by hydrodynamics explains most of the scallop distribution and enlighten the main known hotspots for the population,...
