1. Effect of titanium and nitrogen inoculation on the microstructure, mechanical properties and abrasive wear resistance of Hadfield Steels
Abstract The effect of titanium and nitrogen addition on Hadfield steels was investigated. In order to do this, two grades of steels were produced in terms of titanium and nitrogen addition. The final samples had their microstructure characterized and their mechanical properties were evaluated by uniaxial tensile and Charpy impact tests. Furthermore, the wea

2. Effects of Forming Processes on Microstructures and Mechanical Properties of A356 Aluminum Alloy Prepared by Self-inoculation Method
Semisolid slurry of A356 aluminum alloy was prepared by Self-Inoculation Method (SIM), and the microstructures and solidification behavior of rheo-forming process in different forming processes were researched. The results indicate that semisolid slurry of A356 aluminum alloy can be prepared by Self-Inoculation Method at 600ºC. Primary α-Al particles with

3. The effect of the austenite grain refinement on the tensile and impact properties of cast Hadfield steel
This paper studied the effect of the austenite grain refinement on the tensile and impact properties of a cast Hadfield steel (12 % Mn, 1.2 %C and 0.65 % Si). The austenite grain refinement was obtained by hafnium inoculation. Microstructural characterization showed that the Hf-refined cast Hadfield steel featured a grain size of 600 µm, while the non-refin

4. Crop losses in Brazilian cassava varieties induced by the Cassava common mosaic virus
ABSTRACT Despite the widespread distribution of the Cassava common mosaic virus (CsCMV) in Brazil, little is known about the losses it causes in yield. The effect of CsCMV on different varieties was evaluated by reference to several agronomic traits. Four field trials were established in 2012/2013 and 2013/2014 using six varieties of cassava. Following mecha

5. Mechanical and microstructural characterization of Nodular Cast Iron (NCI) with Niobium Additions
Nodular cast irons (NCIs) involve the inoculation and nodulization of 0.03 to 0.06wt% Magnesium, as well as the addition of Molybdenum, Chromium, Nickel, Copper and Vanadium, although the presence of Niobium is not common. The literature reports that Niobium leads to better mechanical properties of the NCIs, and recent results indicate that 0.5wt% Niobium in

6. The wild type of Momordica charantia is not infected by potyviruses that cause disease in papaya and cucurbit crops
In the present work, the susceptibility of wild and domesticated plants of Momordica charantia to viruses from the genus Potyvirus that cause diseases in papaya (Carica papaya) and cucurbit crops was evaluated. The plants were subjected to experimental and natural infection with Papaya ringspot virus types P and W (PRSV-P and PRSV-W) and Zucchini yellow mosa

7. Characterization of the dry bean polygalacturonase-inhibiting protein (PGIP) gene family during Sclerotinia sclerotiorum (Sclerotiniaceae) infection.
Polygalacturonase-inhibiting proteins are leucine-rich repeat proteins that inhibit fungal endopolygalacturonases. The interaction of polygalacturonase-inhibiting protein with endopolygalacturonases limits the destructive potential of endopolygalacturonases and may trigger plant defense responses induced by oligogalacturonides. We examined the expression of

8. Effect of inoculation on the grain macrostructure of Al-Si alloys obtained by unidirectional solidification. / Efeito da inoculação na macroestrutura de grãos de ligas AI-Si obtidas por solidificação unidirecional.
The development of various industrial sectors, such as the automotive and the aerospace industry, demand premium aluminum castings with strict control of mechanical properties. To fulfill these requirements, the control of solidification processes and the knowledge of relations between the processing variables and the casting properties are necessary. The me

9. Caracterização biológica e molecular do vírus da mancha clorótica de Clerodendrum ( Clerodendrum Chlorotic Spot Virus-CLCSV) / Biological and molecular characterization of Clerodendrum chlorotic spot virus
The botanical genus Clerodendrum belongs to the family Lamiaceae and includes several ornamental species, usually climbing, and heart-bloody (C. x speciosum Tiejism. &Binn.) and tear-in-Christ (C. thomsonae Balf. ) are among the most cultivated. Necrotic and chlorotic spots on leaves of heart-blood have been observed for the first time in a garden of Piracic

10. Influence of water regime in the infection of young citrus plants by Xylella fastidiosa / Influência do regime hídrico na infecção de plantas cítricas jovens por Xylella fastidiosa
In Brazil, about 38% of the citric trees of the São Paulo State are affected by the Citrus Variegated Chlorosis - CVC, causing annual losses of about 100 million dollars for the citrus industries. The causal agent of CVC is a gram-negative, fastidious bacterium inhabitant of the xylem vessels called Xylella fastidiosa. It is vectored by sharpshooter leafhop

11. Influência do número de nódulos de grafita nas propriedades mecânicas do ferro fundido nodular austemperado
In recente years, austempered ductile cast irons (ADI) has emerged as a major engineering material because of its excellent mechanical properties. These properties, as result of a microestructure containing spheroidal graphite and ausferrite, include high strength, ductility, toughness, good wear resistance and machinability. Through the years, the study of

12. Potato clones immune to PVY from crosses between cv. Chiquita and clones simplex for the Ry allele. / Clones de batata imunes ao PVY derivados da cv. Chiquita x clones simplex para o alelo Ry
Clonal families were obtained from biparental crosses between cv Chiquita and clones (named JUG) immune to PVX and PVY. Cultivar Chiquita presents high levels of resistance to early blight (Alternaria solani) and has good general combining ability for this trait. The objective was to generate clones with resistance to the fungus and the viruses diseases. All
