Avaliação da eficiência de extração de compostos nitrogenados da polpa de anchoíta (Engraulis anchoita)

The objective of this work was to evaluate the efficiency of the nitrogen compounds extraction like soluble proteins (SP), total nitrogen (TN), non protein nitrogen (NPN), and nitrogen protein (NP) from the anchovy pulp (Engraulis anchoita), as well to investigate their proximal composition and freshness alteration based on the capture place. The anchovy pulp was submitted to nitrogen extraction treatment using NaHCO3 (0.1; 0.2; 0.3 and 0.5%), NaCl 0.3% as solutions and distilled water. The pulp washing cycles using 0.1% NaHCO3, two cycles of distilled water, and one of NaCl 0.3% demonstrated improved efficiency in the extraction of the nitrogenous compounds and sarcoplasmatic proteins. Concerning the determination of the proximal composition, the anchovy in natura showed moisture content 77.2%, protein 16.8%, lipids 3.4%, and ash 2.4% and the values for the anchovy pulp were moisture 78.1%, protein 17.5%, lipids 2.4% and ash 2%. The freshness evaluation was accomplished through pH, total volatile bases (N-BVT), and trimethylamine (N-TMA) and they were found 6.3; 11.5 mg.100 g-1 and 2.8 mg.100 g-1 for the anchovy in natura and 6.7; 20.2 mg.100 g-1; 3.1 mg.100 g-1 for the pulp, respectively.
Little evidence that lowering the pH of concrete supports greater biodiversity on tropical and temperate seawalls

Concrete is one of the most commonly used materials in the construction of coastal and marine infrastructure despite the well known environmental impacts which include a high carbon footprint and high alkalinity (~pH 13). There is an ongoing discussion regarding the potential positive effects of lowered concrete pH on benthic biodiversity, but this has not been investigated rigorously. Here, we designed a manipulative field experiment to test whether carbonated (lowered pH) concrete substrates support greater species richness and abundance, and/or alter community composition, in both temperate and tropical intertidal habitats. We constructed 192 experimental concrete tiles, half of which were carbonated to a lower surface pH of 7-8 (vs. control pH of >9), and affixed them to seawalls in the United Kingdom and Singapore. There were 2 sites per country, and 6 replicate tiles of each treatment were collected at 4 time points over a year. Overall, we found no significant effect of lowered pH on the abundance, richness, or community assemblage in both countries. Separate site- and month-specific generalised linear models (GLMs) showed only sporadic effects: i.e. lowered pH tiles had a small positive effect on early benthic colonisation in the tropics but this was later succeeded by similar species assemblages regardless of treatment. Thus, while it is worth considering the modification of concrete from an environmental/emissions standpoint, lowered pH may not be a suitable technique for enhancing biodiversity in the marine built environment.
Germination and seedling growth of prairie grass, tall fescue and Italian ryegrass at different temperatures

We measured the effects of temperature on the germination, emergence and growth during early tillering of Italian ryegrass (Lolium multiflorum), prairie grass (Bromus catharticus) and tall fescue (Festuca arundinacea). Radicle emergence (the percentage of seeds with emerged radicles) and 'field' emergence (the percentage of seeds with shoots > 1 cm long) were reduced at 35¦C (constant, all lines), or 30/25¦C (12/12 h, prairie grass and Tama Italian ryegrass only). All lines took longer to germinate at 15 and 10¦C (constant) than at higher temperatures, and final percentage germination of tall fescue lines was lower at 10¦C (constant) than at other temperatures. Italian ryegrass had the fastest shoot extension, and consequently the fastest 'field' emergence. Seed respiration rates were higher in fescue than in the other lines at 4 days from imbibition, and rates rose in all lines at 8 days. Over the first 20 days after sowing, growth rates were closely related (r = 0.87-0.99) to weights of seed and caryopses, when account was taken of perenniality (which was associated with relatively slow growth) and polyploidy (which was associated with growth faster than might be expected from seed size alone), and a multivariate relationship including temperature was developed (R2 = 0.88). Growth rates of shoots at 20 days after sowing were ranked Tama Italian ryegrass > prairie grass > Ucivex Italian ryegrass > tall fescue, and 24/19 > 21/16 > 18/13 > 30/25 > 15/10¦C. Growth during tillering, up to 42 days after emergence, was ranked Italian ryegrass > prairie > tall fescue and 21/16 = 18/13 > 24/19 = 15/1O¦C. Relative growth rates and relative rates of tillering were independent of temperature in Italian ryegrass, but were lower at 15/10 and 24/19 than at 21/16 and 18/13¦C in prairie grass and tall fescue. Prairie grass had higher yield per tiller but lower tiller numbers than Italian ryegrass; tall fescue had both lower yield per tiller and lower tiller number. Italian ryegrass was therefore the species best adapted to variations in environment and competition at sowing.
Growth histories of larval redfish (Sebastes spp.) on an offshore Atlantic fishing bank determined by otolith increment analysis

Larval redfish, Sebastes spp. , were collected for growth analysis on Flemish Cap, an offshore bank approximately 400–500 km east of insular Newfoundland, Canada. There is evidence that larval redfish form one sagittal growth increment daily, starting the day of extrusion from the mother. Length increases linearly with both age and sagittal radius. The mean daily growth rate was 0.16 mm/d in 1980 and 0.11 mm/d in 1981. Length at extrusion varied with date of extrusion in both years. Individual growth histories, inferred from measurements of sagittal radii, varied considerably with age and extrusion date. Larvae typically grew slowly for 10–15 d after extrusion and then rapidly for 60–70 d before slowing as they entered the pelagic juvenile stage.
Relative Survival Benefit by Hormonal Receptor Status of Adding Trastuzumab to Neoadjuvant Chemotherapy in Breast Cancer Patients

Purpose Neoadjuvant chemotherapy (NAC) involving trastuzumab markedly increases pathologic complete response (pCR) rates in patients with human epidermal growth factor receptor 2-positive (HER2+) breast cancer. Despite increasing pCR rates, long-term survival gains are controversial owing to distinctive biologic behavior mediated by the presence of hormonal receptors (HRs) that may interact with HER2 receptors. We, therefore, investigated the differences in relative survival gain provided by neoadjuvant trastuzumab-based chemotherapy on HR positive (HR+) status of patients. Methods We retrospectively analyzed women with stage II or III HER2+ breast cancer who underwent NAC followed by a breast cancer surgery between 2008 and 2013. The survival benefits of adding trastuzumab to NAC were analyzed by classifying patients into HR+ and HR negative (HR−) groups. Results Of 666 patients included in the study, 374 (52.1%) were HR+ and 319 (47.9%) were HR−. In the HR+ group, trastuzumab treatment led to higher pCR rates and significantly better breast cancer specific survival (BCSS) and overall survival (OS) than no trastuzumab treatment. However, among patients with HR− breast cancer, trastuzumab treatment showed no statistically significant difference between BCSS and OS following multivariate analysis. Conclusion We found that the addition of trastuzumab to NAC improved relative survival benefit in HER2+/HR+ patients than in HER2+/HR− patients, even though the pCR rate increases were lower. Although pCR has been regarded as a surrogate marker for estimating long-term survival benefits after NAC, it alone may not translate into real long-term oncologic outcomes in particular cancer subtypes after trastuzumab-based NAC. Further longer-term evaluation of the objective survival benefit after NAC driven by a dual HER2 block according to HR status is warranted.
Beak microstructure analysis as a tool to identify potential rearing stress for Octopus vulgaris paralarvae

Octopus vulgaris is a viable candidate for commercial aquaculture, but rearing procedures might stress individuals and result in diminished growth and survival. This study investigated the relationship between possible stress sources (tank transposition and syphoning) when rearing O. vulgaris paralarvae and the deposition pattern of growth increments in their beak microstructure. Light intensity at the facility was heterogeneous, and accounted for with an experimental design consisting of blocks without replicates. Growth and survival were estimated and possible effects of handling were tested for both parameters. Increments and stress marks were counted in 120 paralarval upper jaws (UJ), and the number of UJs with a mark on the day of stress application (day 8) was quantified. Differences in light intensity, diet quantity and total number of marks in the UJ were also compared between treatments. Growth and survival were statistically similar between treatments, although the control treatment showed a tendency for higher survival rates. Age at first increment deposition coincided with day 1 of experiment, and a 1 increment day 1 deposition rate was validated for the experiment duration. The number of stress marks was significantly different between the control and other treatments, indicating that handling might cause stress and that marks can be used as a biomarker for stress, although the occurrence of stress marks on day 8 was not significantly different. Light intensity and diet might have also been relevant stressors and confounded the results. The results herein presented are important for improving rearing conditions for O. vulgaris paralarvae.
Differential Fluorescent Chromosome Banding of Solanum nigrum L. and Solanum villosum L. from Bangladesh

Two species of the genus Solanum viz. S. nigrum and S. villosum found in Bangladesh were cytogenetically investigated to confirm their taxonomic status. S. nigrum and S. villosum were found to possess 2n=24 and 2n=48 chromosomes, respectively. The centromeric formula 22m+2sm was found in S. nigrum and 48m in S. villosum. No gradual decrease of chromosomal length was observed in both the species indicated their karyotypes as primitive type. The individual chromosomal length ranged from 1.66 to 2.34 μm in S. nigrum and 1.66 to 2.66 μm in S. villosum. The total chromatin length in S. villosum (97.8 μm) was almost double to that of S. nigrum (48.94 μm). The range of relative length of chromosomes was similar in these two species. Solanum nigrum and S. villosum possessed 18 and 17 CMA positive bands, respectively. Most of the CMA-bands were present at the terminal region in both the species. The percentage of CMA banded region in S. villosum (35.43) was almost double to that of S. nigrum (18.69). A pair of DAPI positive bands was found on both the end of all the chromosomes in these 2 species. Each band was 0.5 μm in length. The karyotype of S. nigrum studied here indicated that the specimen was not actually S. nigrum rather it has much simillarities with S. americanum. Solanum villosum showed regular bivalent formation at metaphase-I and segregation at anaphase-I. The overall karyotypic features suggested S. villosum as an ancient auto-tetraploid of S. americanum which in course of time has started regular meiosis.
Diversity and Volume Assessment of Tree Species in the Tropical Forest at Obanla, Akure, Nigeria

This study focused on the assessment of tree species diversity and abundance at The Federal University of Technology, Akure Tropical Forest Obanla. The research was carried out from May, 2019 to September, 2019. Complete enumeration sampling was adopted for the data collection and all trees with diameter at breast height (Dbh) above 0.1 m were identified and measured. Other tree growth variables, such as diameter at the base (db), diameter at the middle (dm), diameter at the top (dt) and the total height were all measured for volume estimation. Ricinodendron heudelotii Hd the highest number of stems (13), so it was the dominant tree species.The result shows that mean tree volume ranges from a minimum of 0.26 m 3 for Olalaceae family, to a maximum of 77.70 m 3 for Euphorbiaceae family. Ceiba pentandra of Malvaceae family had the highest mean volume (14.62 m) while the lowest was recorded for both Khaya senegalensis and Newbouldia laevis with a volume of 0.13 m 2 . The family of Euphorbiaceae was regarded as the dominant family in the natural forest with 26 tree species which is the highest in this study and with the highest volume (77.70 m 2 ). Shannon Wiener diversity index and species equitability index according to Pielou’s of 3.24 Original Research Article Olawoyin et al.; AJRAF, 5(4): 11-19, 2020; Article no.AJRAF. 56230 12 and 0.92 were respectively obtained for the study area. This study revealed the efficacy of an undisturbed natural forest in in situ conservation. Active regeneration can be carried out for proper stocking of the forest so has to make it a potential biodiversity hotspot.
Development and Characterization of Spaghetti with High Resistant Starch Content Supplemented with Banana Starch

Spaghetti developed by substituting semolina with 5, 10, 15, and 20% (w/w) banana starch were evaluated by specific physical and chemical parameters such as chemical composition, resistant starch (RS) content, diameter, bulk density, color, cooked weight, cooking loss, and firmness. They were also evaluated by their sensory attributes. In general, the addition of banana starch promoted a dilution effect on protein, lipid, and ash content, while moisture content was not affected. On the other hand, the content of RS significantly increased ( p50.05) with an increase of banana starch in the spaghetti. Spaghetti containing 5 and 10% of banana starch had similar diameter than the control spaghetti, but the diameter of spaghetti with 15 and 20% banana starch were significantly lower ( p50.05). The bulk density values of spaghetti with banana starch were all similar and not different from the control spaghetti. The values of ΔL* indicated that the color of spaghetti containing banana starch was darker than the control at all levels of substitution, while the values of ΔC* indicated that only spaghetti containing banana starch in the range of 10—20% was less saturated than the control. The evaluation of cooking quality demonstrated that the cooked weight of spaghetti containing banana starch was similar to the control, but their cooking loss was significantly higher and their firmness significantly lower ( p50.05) than the control. However, the values of cooking loss and firmness were in the acceptable range for good quality pasta. Sensory evaluation of the product showed that the addition of banana starch improved the acceptability of the spaghetti. The overall result of this study shows that spaghetti with up to 15% of banana starch addition could have great potential for commercial acceptability as a functional food with high levels of healthy RS.
Stereotypical behavioural cues — but not their order — influence credibility judgements

To what extent stereotypical deceptive behaviours such as gaze aversion and fidgeting actually influence people's credibility judgements remain largely unknown. In this study, we directly manipulated the presence/absence of such behaviours to investigate this. Participants were shown four truthful videos in which we manipulated the presence of stereotypical cues and asked them to judge how credible the person in each video is. Moreover, research consistently shows that decision making is influenced by various cognitive biases. One example is the primacy effect, which implies that people form an opinion early in the decision process. Information acquired early will have the largest influence on how subsequent information will be interpreted. To investigate a possible primacy effect, we also manipulated whether these cues were present towards the beginning or the end of the video (i.e. the timing of the manipulation). In line with our expectations, the presence of stereotypical cues significantly lowered the observed credibility, showing that the presence of these cues indeed influences credibility judgements. The timing of the cues had no effect.
Representing Measurement as a Thermodynamic Symmetry Breaking

Descriptions of measurement typically neglect the observations required to identify the apparatus employed to either prepare or register the final state of the “system of interest. ” Here, we employ category-theoretic methods, particularly the theory of classifiers, to characterize the full interaction between observer and world in terms of information and resource flows. Allocating a subset of the received bits to system identification imposes two separability constraints and hence breaks two symmetries: first, between observational outcomes held constant and those allowed to vary; and, second, between observational outcomes regarded as “informative” and those relegated to purely thermodynamic functions of free-energy acquisition and waste heat dissipation. We show that breaking these symmetries induces decoherence, contextuality, and measurement-associated disturbance of the system of interest.
Student autonomy of feedback format in higher education and perceived functional behaviours for academic development

In the current context of promoting active learning and raising student engagement within Higher Education, an increasing amount of research has looked at pedagogical-based design and factors that contribute to functional behaviours surrounding the interaction and use of academic assessment feedback. However, few studies have considered the perceived influence of student autonomy over feedback format and whether this promotes engagement and academic development. In this study, we recruited level 5 and 6 students (N=38 ) on an undergraduate Education Programme (that has consistently implemented student feedback choice) to participate in initial self-reporting and subsequent focus groups (‘soft triangulation’). The findings revealed three core themes: [1] Personalisation – (a) sense of autonomy/involvement, (b) engagement and (c) motivation, [2] Clarity – (d) depth and detail, and [3] Areas for development. Overall, these findings suggest that feedback type – and the inherent option to choose – has a functional impact on academic engagement and development. We discuss these findings in relation to a sense of being valued that was associated with autonomy of choice, a divergence in how and when students engage with feedback, as well as the requirement for academic clarity and provision of formats that support academic development.
Genotype by environment interaction for somatic cell score in Holstein cattle of southern Brazil via reaction norms

Objective The objective of this study was to evaluate the genetic behavior of a population of Holstein cattle in response to the variation of environmental temperature by analyzing the effects of genotype by environment interaction (GEI) through reaction norms for the somatic cell score (SCS). Methods Data was collected for 67,206 primiparous cows from the database of the Paraná Holstein Breeders Association in Brazil, with the aim of evaluating the temperature effect, considered as an environmental variable, distinguished under six gradients, with the variation range found being 17°C to 19.5°C, over the region. A reaction norm model was adopted utilizing the fourth order under the Legendre polynomials, using the mixed models of analysis by the restricted maximum likelihood method by the WOMBAT software. Additionally, the genetic behavior of the 15 most representative bulls was assessed, in response to the changes in the temperature gradient. Results A mean score of 2.66 and a heritability variation from 0.17 to 0.23 was found in the regional temperature increase. The correlation between the environmental gradients proved to be higher than 0.80. Distinctive genetic behaviors were observed according to the increase in regional temperature, with an observed increase of up to 0.258 in the breeding values of some animals, as well as a reduction in the breeding of up to 0.793, with occasional reclassifications being observed as the temperature increased. Conclusion Non-relevant GEI for SCS were observed in Holstein cattle herds of southern Brazil. Thus, the inclusion of the temperature effect in the model of genetic evaluation of SCS for the southern Brazilian Holstein breed is not required.
Privacy Management and Self-Disclosure on Social Network Sites: The Moderating Effects of Stress and Gender

A plethora of research has examined the effects of privacy concerns on individuals' self-disclosure on social network sites (SNSs). However, most studies are based on the rational choice paradigm, without taking into account the influence of individuals' emotional states. This study examines the roles of stress in influencing the relationship between privacy concerns and self-disclosure on SNSs, as well as gender differences in the effects of stress. Results from a survey of 556 university students in Hong Kong suggest that privacy concerns are negatively related to the amount, intimacy, and honesty of self-disclosure on SNSs. Yet a person's level of stress dampens the association between privacy concerns and disclosure amount and intimacy, suggesting that people may worry less about privacy when highly stressed. Moreover, the moderating effect of stress varies based on gender. This study provides insights into the emotional component of privacy management online.
How to train your neural ODE

Training neural ODEs on large datasets has not been tractable due to the necessity of allowing the adaptive numerical ODE solver to refine its step size to very small values. In practice this leads to dynamics equivalent to many hundreds or even thousands of layers. In this paper, we overcome this apparent difficulty by introducing a theoretically-grounded combination of both optimal transport and stability regularizations which encourage neural ODEs to prefer simpler dynamics out of all the dynamics that solve a problem well. Simpler dynamics lead to faster convergence and to fewer discretizations of the solver, considerably decreasing wall-clock time without loss in performance. Our approach allows us to train neural ODE based generative models to the same performance as the unregularized dynamics in just over a day on one GPU, whereas unregularized dynamics can take up to 4-6 days of training time on multiple GPUs. This brings neural ODEs significantly closer to practical relevance in large-scale applications.
Spectroscopic Measurements of Dissolved O3, H2O2 and OH Radicals in Double Cylindrical Dielectric Barrier Discharge Technology: Treatment of Methylene Blue Dye Simulated Wastewater

Advanced oxidation technologies (AOTs) focusing on nonthermal plasma induced by dielectric barrier discharge are adequate sources of diverse reactive oxygen species (ROS) beneficial for water and wastewater treatment. In this study, indigo, peroxytitanyl sulphate and terephthalic acid methods were used to approximate the concentrations of O3, H2O2 and OH produced in a double cylindrical dielectric barrier discharge (DCDBD) plasma configuration. The effect of pH and scavengers as well as the amount of chemical probes on the generation of oxidants was investigated. The efficiency of the DCDBD reactor was further evaluated using methylene blue (MB) as model pollutant. The results demonstrated that the formation of oxidants O3, H2O2 and OH in the DCDBD reactor was pH-dependent. Furthermore, the presence of scavengers such as phosphates, bicarbonates and carbonates in the solution diminished the amount of OH in the system and hence could impact upon the degree of detoxification of targeted pollutants during water and wastewater treatment. The MB simulated dye was totally decomposed into H2O, dissolved CO2 and simpler aqueous entities. Herein the DCDBD design is an adequate AOT that can be used worldwide for effective decontamination of water and wastewater.
