1. Ecological restoration in pasture areas with direct seeding
Resumo O uso da muvuca de sementes em projetos de recuperação de áreas degradadas vem se destacando em algumas regiões do país devido sua eficácia, menor custo de operação e facilidade na implantação. Neste sentido, o presente estudo teve como objetivo avaliar o potencial da semeadura direta por meio do uso da muvuca de sementes na restauração ec

2. EFFECT OF THE DISTANCE BETWEEN THE CUTTING DISC AND FURROW OPENERS EMPLOYED IN ROW CROP PLANTING ON SOIL MOBILIZATION
ABSTRACT The objective of this study was to determine the effect of the longitudinal distance between a cutting disc and a fertilizer furrow opener on the operational performance of the furrow opener working at different forward speeds during soil mobilization. The soil in the experimental area was classified as Typic Hapludalf with a loam soil texture. The

3. Endoscopic stent in malignant colonic obstruction: the risk of tumor seeding
Resumo Introdução A oclusão intestinal aguda maligna é tradicionalmente considerada uma emergência cirúrgica. Com o desenvolvimento das técnicas endoscópicas surgiram os stents metálicos que asseguram a patência do cólon em doentes não candidatos a cirurgia e, mais recentemente, como uma medida temporária até ser possível realizar uma cirurgi

4. TRACTIVE DEMAND, SOIL MOBILIZATION PARAMETERS, AND CORN YIELD IN COMPACTED OXISOL
ABSTRACT Direct seeding systems are characterized by soil disturbance only occurring in the sowing line and the maintenance of the remaining area is achieved by covering with crop residues. Without total area soil mobilization as recommended by the no-tillage system, associated with the increase in the degree of soil compaction caused by the traffic of agric

5. Human dental pulp stem cell adhesion and detachment in polycaprolactone electrospun scaffolds under direct perfusion
Cell adhesion in three-dimensional scaffolds plays a key role in tissue development. However, stem cell behavior in electrospun scaffolds under perfusion is not fully understood. Thus, an investigation was made on the effect of flow rate and shear stress, adhesion time, and seeding density under direct perfusion in polycaprolactone electrospun scaffolds on h

6. Survival of Saplings in Recovery of Riparian Vegetation of Pandeiros River (MG)
ABSTRACT This study monitored the survival of saplings planted according to different recovery models in a riparian forest of the Pandeiros river (Januária, MG). The models consisted of planting the saplings in lines of 2 or 4 m with presence (T2S and T4S, respectively) or absence of direct seeding (T2 and T4, respectively). We planted 16,259 saplings of 17

7. Survival and growth of tree seedlings as a function of seed size in a gallery forest under restoration
ABSTRACT Seed size is commonly related to higher rates of emergence and survival, and biomass of seedlings when introduced by direct seeding. However, few studies have evaluated whether this relationship persists when species are reintroduced as seedlings or if this effect persists after seed reserves decline. This study evaluated the effect of seed size (ma

8. Avaliação do potencial de regeneração natural e o uso da semeadura direta e estaquia como técnicas de restauração / Assessing the potential of natural regeneration and the use of direct seeding and cutting and restoration techniques
A escolha e caracterização do ecossistema de referencia são fundamentais para orientar as ações de restauração. Além disso, novas técnicas devem ser testadas para aumentar a riqueza e o potencial da restauração ecológica, sendo duas delas a semeadura direta e a estaquia. A área de estudo corresponde a um trecho de pastagem e três fragmentos de

9. ATRIBUTOS DO SOLO E DESEMPENHO DA CULTURA DO MILHO SOB DIFERENTES ALTURAS DE MASSA DE FORRAGEM PÓSPASTEJO / SOIL ATTRIBUTES AND CORN DEVELOPMENT UNDER DIFFERENT HEIGHTS OF FORAGE POST-GRAZING
The Crop-Livestock System (ILP) refers to an association between two activities in the same area at different periods of the year, that involves annual crops and livestock. This study aimed to: (a) evaluate the dry matter yield and residual dry matter remaining of winter intercrop forage (oat, rye and vetch) under different heights of post-grazing residue, (

10. Performance of super hybrid rice cultivars grown under no-tillage and direct seeding
Good progress has been made in the super hybrid rice (Oryza sativa L.) breeding in China. However, rice yield not only depends on the genetic characteristics but also on the agronomic practices. No-tillage and direct seeding (NTDS) is a simplified cultivation technology that greatly simplifies both land preparation and crop establishment. Aiming to determine

11. Micro-sítio como filtro para o estabelecimento de regenerantes arbóreos em áreas restauradas / Microsites as filters for tree species establishment under restoration plantings
The characteristics of the natural regeneration of restoration plantings understory express the main indicators of success of ecological restoration projects, in which the absence of regeneration indicates a bottleneck for the perpetuation of forest communities inserted into highly fragmented landscapes. Nevertheless, adverse conditions of the micro-site of
