1. Guardiani della frontiera: l’intermediazione informale nel ghetto agricolo Sud Europeo
Abstract In agricultural Southern Europe, so-called ghettos are a consolidated phenomenon. In these spaces the most fragile migrants coming from the global South are employed as laborers. These spaces are often framed as the borders of Western modernity, where intermediators operate and reproduce what is defined as new slavery. In this work, drawing from a r

2. Interaction of Lead and Calcium with Biochar Produced from Cassava Waste: Perspectives for Agricultural and Environmental Application
Biochar from slow pyrolysis under controlled conditions is favorable in the transformation of waste into materials that serve as soil conditioners, and/or environmental remediation. Thus, this work aimed to produce and characterize biochar from cassava waste under different temperature conditions and evaluate interactions with Ca2+ and Pb2+ for agricultural

3. CONSTRUCTION AND TESTING OF GLUED LAMINATED TIMBER FRAMES FOR USE IN LAYING POULTRY HOUSES
ABSTRACT This study aimed to present a solution in glued laminated timber to replace frame structures built in reinforced concrete and metallic structure, which are common in agricultural buildings in western Paraná such as those destined to laying poultry house building by agricultural cooperatives. Structural behavior of frames build from Araucaria angust

4. O lazer como fator de permanência e reprodução social no meio rural: estudo do município de Saudade do Iguaçu, PR
Resumo: O lazer e as práticas de atividades recreativas no meio rural são consideradas ações secundárias, pois o rural é percebido como sinônimo de área de produção agropecuária. Nesse contexto, a falta de estruturas que propiciem o lazer e até mesmo a influência social, econômica, política e cultural, favorece um novo esvaziamento do rural. O

5. WIND EFFECTS ON FOUNDATIONS OF SILOS AND LIGHT STRUCTURES: SOLUTION BY USE OF STEEL PILES IN DIABASIC SOIL
ABSTRACT Wind solicitations generate horizontal, tensile, and compressive stresses on building foundations. In empty light structures, such as agricultural greenhouses and, in the specific case of silos and elevated structures such as metal water tanks, the consideration of these loads becomes important because the lack of the weight component due to the sto

6. Investigating the Effect of Delamination Size, Stacking Sequences and Boundary Conditions on The Vibration Properties of Carbon Fiber Reinforced Polymer Composite
Abstract Composite structures are extensively used in various fields ranging from, but not limited to marine, aerospace, automotive, agricultural and industrial equipment due to their unique and excellent properties like weight associated with density. On an increase in their applications, it also requires special attention to manufacture and process the com

7. Estudio teorico de las interacciones de dos modelos de ácidos húmicos con los cationes Al3+, Ca2+, Mg2+, Zn2+, K+ y NH4+ a un nivel de calculo DFT y un modelo de solvatación PCM
In this paper, two models of humic acids, the Temple-Northeastern-Birmingham (TNB) and Kolla models, were studied. Also, the complexation reaction of the structures formed by the interaction of the TNB and Kolla models with Al3+, Ca2+, Mg2+, Zn2+, K+ and NH4+ cations, common in agricultural soils, was studied. These calculations were made for the complexes,

8. SISTEMAS CARREADORES LIPÍDICOS NANOESTRUTURADOS PARA IVERMECTINA E METOPRENO VISANDO CONTROLE DE PARASITAS
The study of characteristics of nanoscale structures and applications now has great interest of researchers from different areas. In this regard, lipid carriers can improve the bioavailability of drugs and the reduction of possible toxicological effects. Thus, the development of nanostructured systems for the agricultural sector, aimed at combating parasites

9. Urease Inhibitors of Agricultural Interest Inspired by Structures of Plant Phenolic Aldehydes
The plant phenolic natural products (PNPs) protocatechuic aldehyde, syringaldehyde and vanillin were used as platforms for obtaining four urease inhibitors. Urea (urease substrate) or thiourea (urease inhibitor) core was added to the structure of newly synthesized compounds to provide inhibitors up to 230-fold more active than the PNPs they originated from.

10. Plant diversity in hedgerows amidst Atlantic Forest fragments
Hedgerows are linear structures found in agricultural landscapes that may facilitate dispersal of plants and animals and also serve as habitat. The aim of this study was to investigate the relationships among diversity and ecological traits of woody plants, hedgerow characteristics (size, age, and origin), and the structure of the surrounding Atlantic Forest

12. SE PLANTA E COLHE ALIMENTOS NESTE SERTÃO: resistência e permanência da autonomia camponesa e as estratégias do MPA (Movimento dos Pequenos Agricultores) nas contradições do projeto da soberania alimentar. / IF THIS PLANT FOOD AND REAP SERTÃO: resistance and persistence of peasant autonomy and strategies of the MPA (Movement of Small Farmers) contradictions in the design of food sovereignty.
This dissertation has the objective of analyze the production unit of the rural family, from the Small Agriculture Movement MPA. To reach this objective, a historic study of the MPA was carried out, its organization, specialization, its relation with the rural way. We focused our research in the territory of the High back-country of Sergipe, which configures
