title: Dris norms for ‘Keitt’ mango in the Brazilian Semiarid Region:Diagnosis and validation

description: Abstract Nutritional standards based on long-term data improve the nutritional diagnosis of the crop, as they make norms more precise and establish more refined criteria. This study aimed to evaluate the nutritional status of the mango crop using the DRIS methodology to identify nutritional limitations and validate norms. A da-tabase of 202 commercial plots was used, whose leaves were collected in the floral induction period between 2011 and 2018 in the Brazilian semiarid region. The productivity of 'Keitt' mango under the Brazilian semiarid conditions was not related to NBI-DRIS. Nutrient concentration presents positive and significant relationship with the respective DRIS indices, enabling the determination of the balance point, establishing a nutritional standard and enabling the use of foliar diagnosis for the variety. The order of nutrients with the highest frequency of limitations due to lack, in decreasing order, was: Zn &gt; Al &gt; Na &gt; Cu &gt; S &gt; B &gt; Mn &gt; P = K &gt; Fe &gt; Ca &gt; N &gt; Mg, and limitation due to excess, in decreasing order was: Fe &gt; Na &gt; Mg &gt; Al &gt; Cu &gt; B = N &gt; S &gt; Ca &gt; P = K &gt; Zn &gt; Mn.

title: Addition of calcitic seaweed in the diet of sows positively affects the number of live-born piglets and milk parameters

description: ABSTRACT This study was conducted to assess the effects of maternal dietary calcitic seaweed (CSW) on performance and blood metabolites of sows, and on performance, blood metabolites, intestinal microbiota, and parameters of gastrointestinal tract and bone of litters. On d 21 (post-insemination), non-pregnant sows were removed from the trial, remaining 19 sows in control group (without CSW) and 16 sows receiving CSW. Then, a total of 35 sows were allocated in a randomized block design with two treatments: control diet with calcitic limestone plus dicalcium phosphate (CTL) or CTL plus 0.4% CSW. In gestation, sows were fed twice a day (07:00 and 15:00 h) to reach an intake of 2.5 kg animal−1 day−1 divided into two equal meals. On parturition day, sows were offered only 0.5 kg feed animal−1. Throughout lactation, sows were fed three times a day (≅7 kg animal−1 day−1). All diets were provided as mash. Results suggested that sows fed CTL had litters with lower body weight at birth compared with those fed CSW. Sows fed CSW had 14.28% more live-born piglets and lower stillborns. Piglets from sows fed CSW showed greater calcium concentration on d 14 after birth than those from sows fed CTL. Sows fed CSW showed better milk chemical composition and an increase of 27.16% in milk production compared with those fed CTL. Piglets from sows fed CSW had an increase in cecum content in the Enterobacteriaceae count. This study showed that adding 0.4% CSW in the diet of pregnant and lactating sows as an organic calcium source positively influences the number of live-born piglets and the percentage of stillborns. In addition, milk composition and production are also improved without affecting piglets’ biological response.

title: Leadership and Human Resources Management Practices: The mediating role of organizational virtues

description: Abstract Considering the unexplored relationship between leadership, organizational virtues, and human resource management practices, the purpose of this paper is to test a structural model of mediation between leadership and human resource management, being organizational virtues the mediating variable. We performed a survey with 673 employees in Brazil, resorting to Structural Equation Modeling to analyze the data. Findings show that organizational virtues mediate the relationship between leadership and HRM practices. We confirm the positive effect of leadership on organizational virtues, the influence of organizational virtues on HRM practices, and the impact of leadership on HRM practices. This paper contributes to the literature on human resource management and organizational behavior, particularly concerning investigations that deal with antecedents of HRM practices.

title: Phosphorus lability in a subtropical Acrisol under long-term integrated crop-livestock system: impacts of grazing management and cropping system

description: ABSTRACT Studies on lability of soil phosphorus (P) under integrated crop-livestock systems (ICLS) are still scarce, especially for deep soil layers (more than 0.20 m depth) and different managements in the crop and livestock phase. Distinct management in these phases may lead to a different distribution of soil P pools according to its lability (labile, moderately labile, less labile and residual) and, consequently, the P availability for plant nutrition. This study aimed to determine the soil P pools, by P fractionation and its distribution in lability classes. In a long-term ICLS experiment of grain and sheep production established in 2003, in Southern Brazil, we sampled in 2017 the 0.00-0.05, 0.05-0.10, 0.10-0.20, 0.20-0.26, 0.26-0.30 and 0.30-0.40 m layers of a Red Dystrophic Acrisol ( Argissolo Vermelho distrófico ) under two cropping systems in the summer (soybean/corn rotation and soybean/soybean succession), two grazing intensities (moderate and low) and two methods (continuous and rotational) in winter. Fractionation of P consisted of sequential extractions with anionic exchange resin, NaHCO 3 0.5 mol L -1 , NaOH 0.1 mol L -1 , HCl 1 mol L -1 , and NaOH 0.5 mol L -1 . The fractions were grouped in four different pools: labile, moderated labile, less labile and residual P. The soybean/soybean succession increased the labile pool of soil P in the 0.00-0.10 m layer compared to the soybean/corn rotation, regardless of the management of the livestock phase. Meanwhile, the management of the livestock phase also influenced soil P lability, regardless of the management of the crop phase. Low grazing intensity increased the levels of labile soil P in the 0.00-0.05 m layer, in comparison with the moderate grazing intensity and regardless of the grazing method. Grazing methods did not impact the soil P lability or content. The greater soil P availability in the soybean/soybean succession can be attributed to the higher quality (low carbon/nitrogen ratio) of the residue, while in the low grazing intensity to the higher forage dry matter production. Such management benefits nutrient cycling and consequently the P availability to the plants, being important to decrease production costs with the reduction and/or greater use efficiency of phosphate fertilizers.

title: A novel approach to Cestrum intermedium (mata-boi): anatomical and physical-chemical characterization, in vitro biological activities, and metabolites of a Brazilian native species

description: Abstract The Brazilian native species Cestrum intermedium, known as mata-boi, induces hepatotoxicity and death when ingested by cattle. While most studies on this species focus on toxicological features, our study is the first to describe the anatomy and in vitro biological activities of Cestrum intermedium. We investigated adult leaves and stems by histochemistry, described their anatomy, performed physical-chemical analysis, determined in vitro antioxidant and antimicrobial activities, and identified secondary metabolites. A few noteworthy anatomical features were the anomocytic stomata on the abaxial surface and the absence of trichomes, in addition to the circular shaped petiole with two projections on the adaxial surface. Histochemical analysis showed chemical markers such as alkaloids, usually reported as toxic, and terpenoids. Potassium nitrate (ATR-FTIR) and lupeol palmitate (NMR) were detected on the crude stem extract. Thermogravimetric and physical-chemical analysis provided fingerprint parameters for the species. Minimal Inhibitory Concentration (MIC) assay revealed that Staphylococcus aureus, Staphylococcus epidermidis, and Candida albicans were weakly inhibited by extract samples. Chloroform and ethyl acetate fractions presented high phenolic content, which resulted in in vitro antioxidant activity. These novel features expand the knowledge about this species, considering that previous studies mainly focused on its toxicity. Our study also provided characteristics that may help in avoiding misidentification between Cestrum members, especially when taxonomic keys cannot be employed, as in the absence of flowers and fruits.

title: Evaluation of antibacterial properties and shear bond strength of orthodontic composites containing silver nanoparticles, titanium dioxide nanoparticles and fluoride: An in vitro study

description: ABSTRACT Objective: The study aimed at determining the antibacterial properties of composites containing silver nanoparticles (Ag NPs) or titanium dioxide nanoparticles (TiO2 NPs), and a fluoride-releasing composite against Streptococcus mutans and Lactobacillus acidophilus, and to evaluate the effect on shear bond strength (SBS) of nanoparticles-modified composites. Materials and Methods: An orthodontic composite was modified by adding 1% w/w Ag NPs or 1% w/w TiO2 NPs. Composite discs were prepared to evaluate the antibacterial properties of these modified composites against Streptococcus mutans and Lactobacillus acidophilus, using three different antibacterial tests, namely: Disk agar diffusion test, Biofilm inhibition test and eluted component test. For evaluating the shear bond strength, 80 extracted premolars were collected and divided into four groups (n=20 each), which were bonded with stainless steel preadjusted Edgewise brackets, by using these modified composites. Their SBS was then compared with that of the control group, using a universal testing machine. Results: Composite discs containing nanoparticles and fluoride were capable of producing growth inhibition zones for all bacterial types. Results of the biofilm inhibition test showed that all the study groups inhibited the bacterial count, in comparison to the control group. A significant difference of SBS was observed between all groups. Conclusion: The antibacterial activity of orthodontic composites modified with Ag and TiO2 nanoparticles was significant, compared with conventional and fluoride-containing composites. The control group showed the highest SBS, followed by fluoride, titanium, and silver groups, with statistically significant difference in mean SBS values among all groups.
