1. Can intramammary infections change immunoglobulins and acute phase proteins of colostrum and transition milk in dairy goats?
RESUMO O proteinograma do colostro/leite pode ser útil para diagnóstico precoce de infecções intramamárias, assim como para a avaliação da intensidade da resposta inflamatória. Este estudo teve como objetivo avaliar o perfil de proteínas, imunoglobulinas, lactoferrina e gamaglutamiltransferase no colostro de cabras leiteiras portadoras de infecçõe

2. Ferrimagnetic to paramagnetic transition and dielectric relaxation in Ni1-xZnxFe2O4 ferrites
Abstract The spinel ferrite system Ni1-xZnxFe2O4 (x=0-0.7, Δx=0.1) was prepared by wet chemical co-precipitation method using sulfates of respective metal ions. The electrical resistivity and dielectric properties of the prepared samples have been studied as a function of temperature, frequency, and Zn content (x). The DC resistivity (ϱ) was measured in th

3. Transition from open partial nephrectomy directly to robotic surgery: experience of a single surgeon to achieve “TRIFECTA”
ABSTRACT Introduction: Recent data suggest that robotic platform has become the most accessible minimal invasive surgery even for surgeons without previous training in laparoscopy. Laparoscopic partial nephrectomy (LPN) is a well-stablished procedure, however, with high level of complexity and long learning curve that limit its use. Objective: To describe

4. CELLULOSE NANOFIBERS FROM CASSAVA AGRO-INDUSTRIAL WASTE AS REINFORCEMENT IN PVA FILMS
Cellulose nanofibers (CNF) have been applied in composite systems due to the abundance of raw material, excellent mechanical and thermal properties. In this work, CNF was prepared from agroindustrial waste and used in specified amounts in polyvinyl alcohol (PVA) composites. The FTIR spectra of CNF, chemically purified cellulose (CPC) and Cassava Agro-industr

7. Clinical utility of the INECO Frontal Screening for detecting Mild Cognitive Impairment in Parkinson’s disease
RESUMO Os déficits cognitivos na doença de Parkinson geralmente afetam as funções executivas. Recentemente, o conceito de Comprometimento Cognitivo Leve (CCL) tem sido relacionado à DP (DP-CCL). O DP-CCL é considerado uma fase de transição para a doença de Parkinson. Portanto, é importante identificar o DP-CCL de maneira acurada. Objetivo: Avaliar

8. Study of Structural and Electric Properties of the PZT 52/48 Doped With Er+3
The scientific community has shown a growing interest in relating to the ferroelectric materials and it has made an effort to develop them. Among these several ferroelectric materials, we proposed to investigated Pb(ZrTi)O3 doped with distinct Er+3 concentrations. Our aim was to investigate how the erbium affects the PZT electrical properties. To determine t

9. Monochromatic double coloring effect on V2O5 thin films deposited by electron beam
ABSTRACT Electrochromic material is a thin film technology that has a close relationship with environmental sustainability since they can control the light and heat that enter and leave a building. Vanadium oxide films are electrochemically active for lithium and electron co-intercalation, presenting low optical variation in the low energy visible light, whi

10. Microstructure and Electrical Characterization of Thermoelectric Nanocrystalline Bi2 Te3 Synthesized by Mechanical Alloying
Nanocrystalline bismuth telluride, Bi2Te3 has been synthesized by mechanical alloying (MA) the powder mixture composed of Bi and Te in the inert gas atmosphere within a short duration of 15 min. Microstructure characterization of the prepared powder has been investigated adopting the Rietveld’s method using X-Ray diffraction (XRD) data and analyzing high-r

12. Methods and rates of poultry litter fertilization for corn silage in organic system
ABSTRACT. The creation of proper soil fertility is fundamental to the agroecological transition phase and guarantees the sustainability of organic agribusiness. In a randomized complete block design with a 3 x 2 factorial scheme with 1 additional treatment (control, without organic fertilizer), we tested three poultry litter rates (7, 14, and 21 Mg ha-1) at
