1. Analysis of Al2O3-ZrO2 ceramic insert in turning process of Ti-6Al-4V alloy using grey Taguchi-based response surface methodology (GT-RSM)
Abstract The present investigation aimed at a sustainable green turning operation of Ti-6Al-4V alloy using multi-objective optimization of surface roughness, tool flank wear, material removal rate, and tool wear loss with cutting speed, feed rate, and depth of cut as input parameters. The experiments were performed on a CNC lathe machine using an alumina-zir

2. Laser cutting machine-induced maculopathy and spontaneous recovery
RESUMO Os efeitos térmicos das máquinas de corte a laser podem danificar a mácula. Poucos estudos na literatura tem descrito a lesão macular por queimadura a laser industrial. Neste estudo, objetivamos relatar os achados clínicos, visuais e de tomografia de coerência óptica em um trabalhador de refinaria de ouro com maculopatia induzida por laser. O t

3. Influence of shadowing in Sequoia sempervirens (D. Don) Endl. mini-stumps and mini-cuttings
ABSTRACT The aim of the work was to analyze the influence of variables such as shading, temperature and humidity in the production and rooting of mini-cuttings of Sequoia sempervirens (D. Dom) Endl. in a clonal mini-garden. The experiment was conducted at the Forest Nursery at the University of Santa Catarina State - CAV/UDESC, Lages - SC. The minicuttings w

4. Response of black mulberry onto white mulberry rootstock to stenting (cutting-grafting) techniques and IBA concentrations
Resumo A amoreira-preta (Morus nigra L.) é uma planta ornamental utilizado no paisagismo por ser uma planta que proporciona sombreamento, tolera a poluição do ar e o vento. A amoreira-branca (Morus alba L.) é adequada para várias condições de solo. Esta pesquisa foi conduzida para investigar os efeitos dos métodos de enxertia por garfagem e dos níve

5. Effects of cutting on vegetative development and biomass quality of perennial halophytes grown in saline aquaponics
RESUMO O cultivo de plantas vasculares na aquicultura está se tornando cada vez mais importante e a aquaponia salina tem centrado no cultivo de plantas com o ciclo de vida curto (i.e. plantas anuais). Entretanto, o cultivo de plantas perenes pode permitir a produção de biomassa durante todo o ano por cortes repetidos e rebrote. O presente estudo avaliou o

6. Adventitious rooting of cultivars and clonal selections of Prunus spp. rootstock under intermittent mist system
ABSTRACT To reduce peach tree losses due the Peach Tree Short Life (PTSL), the main research line in Brazil is to select tolerant rootstock and perpetuate it by cloning methods. The objective was to evaluate adventitious rooting capacity of softwood cuttings of three cultivars and several clonal rootstock selections of Prunus spp., under intermittent mist s

7. 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

8. Mini-cutting rooting and plantlet growth in Erythrina crista-galli L.
ABSTRACT In this study, we evaluated the adventitious rooting competence of mini-cuttings and plantlet growth of two clones of swamp cork (Erythrina crista-galli L.). Experiments were carried out in a factorial of two clones to study the need of application of indolebutyric acid (IBA), substrate composition for mini-cutting rooting and plantlet growth, and r

9. INSECTICIDAL AND FUNGICIDAL ACTIVITY OF A MAGNESIUM COMPOUND CONTAINING ISOVANILLIC ACID AGAINST LEAF-CUTTING ANT AND ITS SYMBIOTIC FUNGUS
Pesticides offer a simple, cost-effective solution to ensure food supplies for a growing world population. However, their environmental performance needs improvement if pesticides are to continue contributing importantly. This study explores the insecticidal potential of a magnesium (II) metal complex containing 1,10-phenanthroline and isovanillic acid (MgPh

10. Single-Layered Paper-Based Microfluidic Devices Made by Paint-Spraying Technique with Great Barrier Resistance for Colorimetric Assays
The single-layered paint-spraying paper based microfluidic devices (sp-μPADs) have been for the first time integrated with the colorimetric assay. The polymethyl methacrylate (PMMA) board was applied as the mask instead of the iron mask, reducing the power requirement of the cutting machine. The paint was sprayed into the paper, which blocked the pores of t

11. SUGARCANE BASE CUTTING QUALITY USING RECTANGULAR AND CIRCULAR BLADES
ABSTRACT Sugarcane mechanized harvesting can lead to serious risks to the longevity of plantations when improperly operated, and may cause damages and disturbances in the remaining ratoons in the field. In this sense, this study aimed to evaluate the damage and disturbance to the sugarcane ratoons by the base cutting quality of two-blade models through stati

12. Odontadenia lutea (Apocynaceae) LEAVES: PHYTOCHEMICAL STUDY AND INSECTICIDAL ACTIVITY AGAINST LEAF-CUTTING ANTS Atta sexdens rubropilosa Forel
The present work describes the chemical constituents of Odontadenia lutea (Vell.) Markgr. leaves and the toxicities of its extract and fractions against Atta sexdens rubropilosa Forel (Hymenoptera: Formicidae). Chromatographic procedures of the ethanolic extract resulted in the identification of the triterpene β-amyrin, the flavonoid rutin, two fatty acids
