title: Volatile Metabolomics from Cashew Leaves: Assessment of Resistance Biomarkers Associated with Black Mold (Pilgeriella anacardii Arx & Müller)

description: Black mold, a disease caused by the fungus Pilgeriella anacardii Arx & Müller, affects cashews (Anacardium occidentale). Some cashew clones are more resistant to the pathogen; however, little is known about the chemical profile responsible for this trait. The investigation of volatile organic compounds (VOCs) from leaves of dwarf cashew clones resistant (BRS 226 and BRS 265) and susceptible (CCP 76 and BRS 189) to the pathogen was carried out. Leaves were collected during the months of disease incidence and decline (March to July 2019, Brazil), and VOCs were analyzed by gas chromatography-mass spectrometry (GC-MS) combined with chemometric tools. The GC-MS analysis tentatively identified 96 compounds. Partial least squares discriminant analysis (PLS-DA), orthogonal partial least squares discriminant analysis (OPLS DA), hierarchical cluster analysis (HCA), and ROC curves analysis were useful in dividing VOCs into distinct resistance and associated chemical susceptibility groups for different clones. The VOCs in the leaves of the resistant clones were identified as alcohols and aldehydes containing six carbons: (E)-hex-2-enal, hex-3-en-1-ol, (Z)-hex-2-en-1-ol, (E)-hex-2-en-1-ol, and hexan-1-ol. Moreover, α-pinene, pseudolimonene, α-phellandrene, β-myrcene, sylvestrene, β-cis-ocimene, methyl salicylate, myrtenol, α-copaene, γ-muurolene, germacrene D, valencene, and germacrene B were also detected in these samples and may be candidate chemical biomarkers for cashew resistance to P. anacardii.

title: Open access in the context of Information Science research

description: Abstract Open access is a scientific dissemination mechanism that aims to democratize access to scientific research results, removing barriers to access and permission to published content. Such barriers often marginalize authors, institutions, or countries with less financial resources. In this context, this work aims to understand the world scenario of open access research, in the field of Information Science, in the last six years (2015 to 2020) and to identify possible suggestions that can improve the future of research on this subject. Bibliometric analysis was used to achieve these objectives. We used Scopus database as a source of information, combined with the SciVal tool. As a result, 1139 documents were retrieved on the open access area, and from the analyses, it was possible to characterize the sample, identify the main contributors and verify the quality of research on the open access field. We were also able to identify the main actors in the international scope, the research areas most engaged with the open access and to propose, from the complementary literature, a proposal to promote open access research through international and national collaborations among other authors.

title: Morphological Studies on the Testis, Epididymis and Vas Deferens of Al-Ahsa Native Rooster

description: ABSTRACT This study was carried out to investigate the morphological and histological structures of the testis, epididymis and vas deferens of the Al-Ahsa native rooster (ANR). There were two types of ANR; the brown feather one with light yellow shank and the black feather one with grey or dark grey shank. Their body weight was 1840.88± 92.13 g and 1555.66± 82.83g, respectively. The morphology of the testes showed that the black rooster has larger testes than the brown rooster and there was asymmetry in size between the right and left testis in both. They were grey yellowish in color and oval-shaped, situated in the abdomen dorsal to the proventriculus, the liver and the gizzard, cranial to the lungs, caudal to the abdominal sac and ventral to the kidneys. The histology of the testes revealed the capsule, the different cells of the lining epithelium of the seminiferous tubules and the interstitial tissue. The morphology of the epididymis was revealed pseudostratified columnar epithelium, light brown in color with c to L-shaped, located cranial to the testis and extended caudally to continue with vas deferens. The latter has columnar epithelium, light grey in color, run caudally medial to the kidneys and opened in the cloaca.

title: DESIGN AND EXPERIMENT OF A CLAMP-HOLDING PRECISION MAIZE-SEED-METERING DEVICE

description: ABSTRACT To solve the current problems of poor seeding stability and complex maintenance of maize seed-metering devices, a clamp-holding precision maize-seed-metering device is designed. The structure and working principle of the seed-metering device are described, the optimum state of maize seed clamping is analyzed, and the range of each working area of the seed-metering device is determined. The profile and structural parameters of the limit guide plate are designed by analyzing the laws of motion of the seed-picking block. A mechanical model of maize seeds under the critical state in each working area of the seed-metering device is established. The influence of the seed-metering device's rotational speed and the clamping force of the seed-picking block on the seeding performance are analyzed. A physical prototype of the seed-metering device was made for bench tests and field verification tests. The qualified, multiple seeding, and missed seeding rates of the designed seed-metering device were 94.21%, 3.52%, and 2.27%, respectively, meeting the agronomic requirements of maize sowing. The study provides theoretical guidance for designing and optimizing precision maize-seed-metering devices.

title: Brazilian Bibliometrics: coword analysis

description: Abstract The analysis of 6,180 documents produced and published on Brazilian bibliometrics up to December 2018 were realized. To collect the documents, titles, keywords, and abstracts were searched using different languages and Boolean combinations of documents indexed in bibliographic databases. These documents used 6,307 distinct keywords, of which 4,215 were used only once and one-word (Scientific production) 1,054 times. The analysis of the keywords identified in the 6,180 documents was done using the MPA (Associated Words Method) package from R programming language. The co-word analysis as a technique allowed to identify the thematic concerns of Brazilian bibliometrics. A maturing field of study clearly linked to the field of information science, which has its center of analysis in indexing and documentary language. It also identified the central subject of management and accounting research with poor links to marketing and science & technology.

title: Interaction of Lead and Calcium with Biochar Produced from Cassava Waste: Perspectives for Agricultural and Environmental Application

description: 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 and environmental applications. To investigate the efficiency of the interaction of biochar with nutrients (Ca) and contaminants (Pb), the influence of pH and contact time were evaluated. There was an increase in pH, pHzpc (zero point charge), and condensed aromatic structures in BC, due to the increase in pyrolysis temperature. Also, biochar demonstrated a Pb2+ adsorbed amount of 2.03 to 2.37 mg g-1 and a Ca2+ release capacity of 0.655 to 0.765 mg g-1. In this way, biochar produced from residues of cassava waste can be a viable strategy to enhance agricultural production and reduce environmental contaminants.

title: Metabolomic and Histological Response of Passiflora cincinnata Infected with Cowpea aphid-borne mosaic virus (CABMV) Reveals Changes in Asymptomatic and Symptomatic Phases

description: Passion fruit woodiness disease, caused by the Cowpea aphid-borne mosaic virus (CABMV), is one of the leading phytosanitary challenges of passion fruit production. Passiflora cincinnata has been recognized for its potential in genetic improvement due to its highest resistance to CABMV and other phytopathogens. Metabolomic and histological alterations of P. cincinnata infected with CABMV were evaluated and searched for differential responses during the asymptomatic or symptomatic infection phases to correlate them with the mechanisms of metabolic defense. The metabolites of infected plants were analyzed by liquid chromatography-mass spectrometry. Based on the metabolomic profile, the times of infection were grouped into early or late infection phases. The metabolites related to CABMV infection were classified as alkaloids, saponins, phospholipids and acids. This study can assist agricultural institutions or farms in the early diagnosis and correct management of CABMV infection and contribute to the genetic improvement of the Passiflora genus against this disease.

title: High Doses of Phytase Alleviate the Negative Effects of Calcium and Phosphorus Imbalance on Growth Performance and Bone Mineralization in Broiler Chickens

description: ABSTRACT This study investigated the effect of calcium (Ca) and phytase interaction on growth performance and bone quality in 1-42-day-old broiler chickens. A total of 624 female one-day-old Ross 308 broilers were allotted to 13 treatments with four replicates and 12 birds per replicate. A 2 × 6 factorial experiment was designed to test the combinations of 0.50% and 1.00% Ca with 0, 500, 1,000, 2,500, 5,000, and 10,000 FTU/kg phytase in the basal diet (0.25% non-phytate phosphorus, NPP). The control diet contained adequate Ca and phosphorus (P). Dietary Ca, phytase, and their interaction affected growth performance and bone mineralization of broilers at 1-42 days of age (p&lt;0.05). The broilers fed with 1.00% Ca had lower body weight gain (BWG) and feed intake (FI) compared with the birds fed with 0.50% Ca (p&lt;0.05). The BWG, FI, leg bone weight, and ash weight of the broilers fed with 0.25% NPP were lower than those of birds fed with the control diet (p&lt;0.05). The addition of 500-10,000 FTU/kg phytase improved growth rate and leg bone quality, especially at 1.00% Ca (p&lt;0.05). No differences were observed in growth performance and bone quality of 42-day-old broilers fed with 1.00% Ca + 2,500-10,000 FTU/kg phytase and the control diet (p&gt;0.05). These data indicated that high doses of phytase (2,500-10,000 FTU/kg) alleviate the negative effects of Ca and P imbalance (Ca-to-NPP ratio = 4.0) on growth performance and bone mineralization of broiler chickens.

title: Assessment of cone beam computed tomography for determining position and prognosis of interradicular mini-implants

description: ABSTRACT Objective: To investigate the influence of dynamic visualization of cone beam computed tomography (CBCT) scans on orthodontist’s assessment of positioning status and prognosis of interradicular mini-implants (MI). Methods: Three MI positions were virtually simulated in thirty CBCT volumes: (1) MI 1 mm from the lamina dura (LD), (2) MI touching the LD and (3) MI overlapping the LD. Each position was exposed to orthodontists (n = 35) as panoramic reconstruction, sagittal reconstruction and a sequence of axial slices. Each orthodontist evaluated the MI position (relationship with the LD) and scored the prognosis using a four-point scale (the higher the score, the better the prognosis). Kappa, Friedman and Nemenyi statistics were used. Results: Statistically significant associations were detected between the prognosis scores and the type of image visualized (p&lt;0.05). The dynamic visualization of the CBCT volume (axial slices) was associated with higher scores for prognosis and more reliable evaluation of MI positioning. Inconsistent outcomes were more frequently associated with panoramic and sagittal reconstructions. Conclusion: The dynamic visualization of axial slices allowed orthodontists to perform better assessment of MI position and considerably affected prognosis judgment.
