Compostos bioativos e atividade antioxidante de frutos de genótipos de cajá-mangueira

Alguns frutos de plantas do gênero Spondias são apreciados pelos aspectos de sabor e aparência atrativos. Contudo, durante a maturação ocorrem mudanças acentuadas que modificam a qualidade, sobretudo nessas plantas que não são plenamente domesticadas. Por terem frutos ricos em compostos antioxidantes, a pesquisa com tais frutos tem focado em compreender as mudanças que estes apresentam na maturação. Este trabalho teve como objetivo avaliar as mudanças nos compostos bioativos e na atividade antioxidante ocorridas durante a maturação de frutos de genótipos de cajá-mangueira (Spondias cytherea Sonn.). Os frutos provenientes de cinco genótipos (P1, P2, P3, P4 P5) de ocorrência espontânea no estado da Paraíba foram colhidos nos seguintes estádios de maturação: totalmente verde (TV), início de pigmentação amarela (IP), amarelo esverdeado (AE) e predominantemente amarelo (PA). O experimento foi conduzido em delineamento inteiramente casualizado, em esquema fatorial 5 x 4, sendo cinco genótipos e quatro estádios de maturação, em seis repetições. A polpa dos frutos foi avaliada quanto ao conteúdo de ácido ascórbico, carotenoides totais, flavonoides amarelos, antocianinas, polifenóis extraíveis totais (PET) e atividade antioxidante total (AAT). Os frutos da cajá-mangueira apresentaram aumento no conteúdo de carotenoides e antocianinas da polpa, redução nos PET e flavonoides amarelos e aumento da AAT ao final da maturação. A atividade antioxidante do cajá-manga aumentou ao final da maturação. O genótipo P3 destacou-se entre os demais por apresentar maior conteúdo de carotenoides totais e flavonoides amarelos ao final da maturação (PA), enquanto os genótipos P1 e P5 por apresentarem maior capacidade antioxidante.
Familiar strangers – managing engagements in public-private partnerships in education

ABSTRACT Various forms of public-private collaborative organizations have been emerging in the education sector, a development that has made managing public-private partnerships an unavoidable imperative for school managers today. Addressing interactions between the partnership manager of and partners in a public-private innovation partnership, this article explores the attachments public and private actors establish in the framework of such partnerships. While formal structures often bind partnerships together, open innovation partnerships have a more fluid organization in which the participants have to establish the ground for their common work. Specifically, the article presents a study of a Danish partnership project aimed at developing a new secondary school. Drawing on the sociology of engagements, the article sketches out the differing forms of mutual engagements at stake between the actors involved and the challenges they face. As the partnership studied lacked formal agreements, the manager’s and partners’ locally performed acts of proximity became a means of binding the partnership together. In these acts, a mutual explorative engagement intertwined with a familiar engagement, thus creating a distinct attachment of familiar strangers between the public and private actors – an attachment through which ideas on education and common educational visions could traverse the public and private sectors.
Spatiotemporal Evolution of Microseismicity Seismic Source Properties at the Irpinia Near-Fault Observatory, Southern Italy

We estimate the source parameters of small-magnitude earthquakes that occurred during 2008–2020 in the Irpinia faults area (southern Italy). We apply a spectral decomposition approach to isolate the source contribution from propagation and site effects for ∼3000 earthquakes in the local magnitude range between ML 0 and 4.2. We develop our analyses in three steps. First, we fit the Brune (1970) model to the nonparametric source spectra to estimate corner frequency and seismic moment, and we map the spatial distribution of stress drop across the Irpinia area. We found stress drops in the range 0.4–8.1 MPa, with earthquakes deeper than 7 km characterized by higher average stress drop (i.e., 3.2 MPa). Second, assuming a simple stress-release model (Kanamori and Heaton, 2000), we derive fracture energy and critical slip-weakening distance. The spatial variability of stress drop and fracture energy allows us to image the present stress conditions of fault segments activated during the 23 November 1980 Ms 6.9 earthquake. The variability of the source parameters shows clear patterns of the fault mechanical properties, suggesting that the Irpinia fault system can be divided into three main sectors, with the northern and southern ones showing different properties from the central one. Our results agree with previous studies indicating the presence of fluids with different composition in the different sectors of the Irpinia fault system. In the third step, we compare the time evolution of source parameters with a time series of geodetic displacement recorded near the fault system. Temporal trends in the correlation between geodetic displacement and different source parameters indicate that the poroelastic deformation perturbation generated by the karst aquifer recharge is modulating not only the occurrence rate of microseismicity (D’Agostino et al., 2018) but may lead to rupture asperities with different sizes and characteristics.
Nanoporous Carbons: Porous Characterization and Electrical Performance in Electrochemical Double Layer Capacitors

Nanoporous carbons have become a material of interest in many applications such as electrochemical double layer capacitors (supercapacitors). Supercapacitors are being studied for their potential in storing electrical energy storage from intermittent sources and in use as power sources that can be charged rapidly. However, a lack of understanding of the charge storage mechanism within a supercapacitor makes it difficult to optimize them. Two components of this challenge are the difficulties in experimentally characterizing the sub-nanoporous structure of carbon electrode materials and the electrical performance of the supercapacitors. This work provides a means to accurately characterize the porous structure of sub-nanoporus carbon materials and identifies the current limitations in characterizing the electrical performance of a supercapacitor cell. Future work may focus on the relationship between the sub-nano porous structure of the carbon electrode and the capacitance of supercapacitors, and on the elucidation of charge storage mechanisms.
Social Distance of University Students towards Individuals with Special Needs

ABSTRACT People acquire professional knowledge and skills throughout university education during which their social relations network, orientation and social perceptions are also shaped. Due to the importance of university education period, the purpose of this study was to determine the social distance levels of the university students towards individuals with special needs. The study group consisted of a total of 1293 students continuing their university education in a province located in southeastern Turkey. The Bogardus Social Distance Scale was used as the data collection tool in this descriptive study. The results revealed that the participants indicated the greatest social distance towards individuals with intellectual disabilities and autism while the lowest distance was observed towards gifted individuals. It was found that most of the university students do not prefer to ‘get married’, ‘become a close kin member by marriage’ and ‘become a fellow employee (co-worker)’ with individuals with special needs. The results also revealed that students’ knowledge about special needs groups and their contact frequency with individuals with special needs are significant factors affecting their social distance. However, social distance does not differ with respect to gender of the participants.
Exploring the Citywide Human Mobility Patterns of Taxi Trips through a Topic-Modeling Analysis

Understanding human mobility patterns is of great importance for a wide range of applications from social networks to transportation planning. Toward this end, the spatial-temporal information of a large-scale dataset of taxi trips was collected via GPS, from March 10 to 23, 2014, in Beijing. The data contain trips generated by a great portion of taxi vehicles citywide. We revealed that the geographic displacement of those trips follows the power law distribution and the corresponding travel time follows a mixture of the exponential and power law distribution. To identify human mobility patterns, a topic model with the latent Dirichlet allocation (LDA) algorithm was proposed to infer the sixty-five key topics. By measuring the variation of trip displacement over time, we find that the travel distance in the morning rush hour is much shorter than that in the other time. As for daily patterns, it shows that taxi mobility presents weekly regularity both on weekdays and on weekends. Among different days in the same week, mobility patterns on Tuesday and Wednesday are quite similar. By quantifying the trip distance along time, we find that Topic 44 exhibits dominant patterns, which means distance less than 10 km is predominant no matter what time in a day. The findings could be references for travelers to arrange trips and policymakers to formulate sound traffic management policies.
Assessment of a Novel Surgical Technique for Acoustic Transmitter Insertion

This study compared three surgical techniques to implant acoustic transmitters in rainbow trout (Oncorhynchus mykiss): 1) acoustic transmitter insertion via a ventral incision closed with two sutures, 2) insertion via a ventral incision with no sutures, 3) insertion via a lateral incision with no sutures. A control group consisting of fish that were only anesthetized and handled was also included. Tag retention, wound healing, inflammation, growth, and survival were recorded over a 12-week period. Tag retention was significantly different among the treatments, at 100% in the unsutured ventral incision group, 89% in the lateral incision group, and 63% in the sutured ventral incision group. Surgical wounds in the unsutured treatment groups showed significantly less inflammation than the sutured treatment. Wound closure occurred significantly faster in the ventral incision groups compared to the lateral incision group. The results of this study show the utility of using unsutured surgical methods for implanting acoustic transmitters in rainbow trout.
Evaluating Carotid intima media thickness (CIMT) of patients with Non - Alcoholic fatty liver disease (NAFLD) as a risk factor for atherosclerosis and correlation with metabolic syndrome

This study aimed to evaluate the effect of NAFLD on CIMT as a risk factor for atherosclerosis. The incidence of non-alcoholic fatty liver disease (NAFLD) is escalating worldwide due to mount of obesity and diabetes mellitus (DM) prevalence. Non-invasive appraisal of carotid intima-media thickness (CIMT) by high-resolution carotid B-mode ultrasonography is broadly used for determining atherosclerosis. In this case-control setting, 151 subjects were categorized in three groups: group I counting 49 patients with NAFLD and DM; group II counting 50 non-diabetic NAFLD patients; and the control with 52 normal subjects as group III. The right and left CIMTs and its maximum reading (CIMT max) were deliberated by a skilled sonographist blind to the groups. The sonographic grading of the NAFLD was dogged in groups I and II. Median CIMT max was extensively higher in group I comparing with group II and control group (p<0.001). This disparity between group I and group II were not significant after adjusting for age and history of hypertension and hyperlipidemia (p=0.089). After scheming the confounders, there was a statistically significant between-group I and group II with the control group (p<0.05). There was no significant disparity in median maximal thickness of intima-media in the carotid of group I compare to group II in patients with and without prominent liver enzymes (in both groups, 0.6 mm, p= 0.402). Based on our findings, there is a significant relationship between the presence of NAFLD and atherosclerosis. This association was independent to the Diabetes mellitus presence. The grade of NAFLD and elevated liver function tests had no effect on the severity of atherosclerosis.
Knowledge management in the environment of cross-functional team coopetition: A systematic literature review

Knowledge is crucial, but a transient resource that decides over the success or failure of business operations. Consequently, companies aim for the most profitable method to achieve high gains and conservation of knowledge, while excluding rivals to maintain the position of economic advantage as long as possible. To maximize the efforts of knowledge generation, new concepts of organizational processes were established in recent years. To provide a conceptual foundation and identify promising niches for future studies in the important field of team coopetition, existing literature on the factors of cross-functional team coopetition was reviewed, concluding in a systematic review. For this purpose, leading peer-reviewed journals from 2010 to 2021 offered 25 articles that fall within its established search inclusion criteria. Adding to the change of stakeholder project management, the shift from traditional, cooperative-led organizational approaches towards coopetition between two or multiple rivals can lead to promising results. However, it was indicated that this concept often fails due to misleading coordination in a coopetitive tension. Current studies extracted their results from applied team management mostly on short-term organizational, financial, and technical benefits or drawbacks, excluding long-term innovation effects. Most studies were categorized into three outcomes contributing to knowledge management: performance, relationship, and innovation. As a result, it is pointed out that several factors derived from the literature significantly influence the outcomes.

A Severe Case of Spondylometaphyseal Dysplasia Algerian Type with Two Mutations in COL2A1

Abstract Spondylometaphyseal dysplasia Algerian type (MIM no.: 184253) is an uncommon autosomal dominant skeletal dysplasia caused by heterozygous mutations in the COL2A1 gene (MIM no.: 120140). In this case based review, we reported a 5-year-old boy with short stature, severe dorsolumbar scoliosis, lumbar hyperlordosis, short trunk, and severe genu valgum . Radiological examination showed platyspondyly, irregular metaphyseal radiolucencies intermingled with radiodensities, and corner fractures. The patient has a c.3275G > A; p.Gly1092Asp mutation in exon 47 of the COL2A1 gene and a variant of unknown significance in c.1366–13C > A in intron 21. This latter sequence variant could partially or completely disrupt the natural splice acceptor site of intron 21/exon 22 in the COL2A1 gene leading to a potential modification of the phenotypic severity.
Ultrafast Trap State-Mediated Electron Transfer for Quantum Dot Redox Sensing

Quantum dots (QDs) conjugated to electron acceptor ligands are useful as redox sensors in applications ranging from chemical detection to bioimaging. We aimed to improve effectiveness of these redox-sensing QD conjugates, which depends on the initial charge separation and on the competing mechanisms of recombination, including luminescence and electron transfer to the conjugated redox molecules. In this study, ultrafast laser measurements were used to study the excited state dynamics in CdTe/CdS core/shell QDs with quinone/quinol acceptor (Q2NS) ligands attached to the surface (up to 40 per QD). Detailed analysis, along with computational modeling of the system, showed multiple electron-transfer pathways and identified an ultrafast electron transfer from a surface electron trap state to the quinone ligands (2–8 ps). We propose that this leads to high, redox-dependent, quenching efficiencies (98.7% with an average of 10 quinone/quinols on the surface). As only low populations of redox ligands are required,.
The modulation of emotional awareness using non-invasive brain stimulation techniques: a literature review on TMS and tDCS

ABSTRACT Emotional awareness is defined as the conscious experience of emotions and plays an important role in realising the link between our feelings and what we think, do and say. In this literature review, we included studies examining those alterations in emotional awareness elicited by non-invasive brain stimulation techniques, specifically by the transcranial magnetic stimulation (TMS), and the transcranial direct current stimulation (tDCS). The anodal tDCS over the dorsolateral prefrontal cortex increases the ability to discriminate facial expressions; TMS over the dorsomedial prefrontal cortex significantly interferes with emotion recognition abilities. Similarly, the ventrolateral prefrontal cortex contributes to emotional recognition abilities. Stimulations by repetitive repetitive TMS over the right intraparietal sulcus, improve the identification of emotions. The anodal stimulation over the orbitofrontal cortex, over the posterior superior temporal sulcus and over the right temporo-parietal junction, contributes to enhance emotion recognition abilities. The findings obtained from this work suggest that the brain stimulation techniques over specific brain regions may facilitate the increase of emotional awareness contributing to improve the psychological well-being of individuals.
Statistical downscaling of daily precipitation over southeastern South America: Assessing the performance in extreme events

The performance of multiple empirical statistical downscaling (ESD) methods was assessed for simulating daily precipitation during 1979–2017 over southeastern South America (SESA), a region where extremes are remarkable. Meteorological stations were used as reference and three gridded precipitation products were included to account for observational uncertainty. The set of ESD models involved different configurations of the analogue method (ANs), deterministic and stochastic versions of neural networks (NNs) and generalized linear models (GLMs) and circulation‐conditioned GLMs (GLM_WTs). The years with the largest number of extreme events (wet years) were calibrated separately. The spatio‐temporal variability of extremes was assessed by analysing their intensity, spatial extent, frequency and interannual variability. An overall good performance of the ESD models was found for several aspects of daily precipitation. ESD performance dispersion was usually contained in the observational spread. No particular model configuration was found to perform best in all aspects, indicating the advantage of considering a multi‐model ensemble. The ANs tended to follow the stations, satisfactorily simulating daily precipitation and its extremes. The deterministic GLMs strongly underestimated precipitation estimates and were not able to represent extreme frequencies and intensities, but this was alleviated by employing a stochastic version of the method. Furthermore, the use of weather types to condition the GLMs (GLM_WTs) considerably improved model performance, particularly for the annual cycle and the spatial structure of extreme precipitation. The NNs adequately reproduced the spatial behaviour and intra‐annual variability of extreme precipitation, although they underestimated its intensity in their deterministic version. An analysis of the regional time series of extremes showed consistency among datasets and evidenced the influence of the ENSO teleconnection on the wet years, which were commonly well‐simulated by the statistical models. ESD models presented good skills in simulating a wetter climate over SESA, which is of particular importance in a climate change scenario.
CO-INTEGRATION AND ERROR CORRECTION MODELING OF AGRICULTURAL OUTPUT: THE CASE OF CASSAVA IN ONDO STATE, NIGERIA

Cassava is an important food crop in Nigeria providing households food security and income. Cassava production has received government and stakeholders’ intervention dating back to the 1970s. Nevertheless, increased and sustainable production of the crop is under threat by exogenous factors of climate change and variability. This study investigates this concern by assessing the effects of climate change on cassava output in Ondo state, Nigerian using Co-integration and Error-Correction Modelling (ECM). Time series (1971-2010) data were sourced from the Central Bank of Nigeria (CBN), National Bureau of Statistics (NBS) Abuja, Nigerian Meteorological Agency Oshodi, Lagos. The results of the Augmented Dickey-Fuller (ADF) test revealed that all variables (cassava yield and climate variables; rainfall, temperature, and relative humidity) all have unit root problems (non-stationary) but become stationary after the first difference 1(1). The results confirmed a long-run equilibrium relationship between all identified variables as the absolute values of the variables are greater than their critical values at a 5% level of significance for both trace statistics and maximal-eigen values. The ECM result shows that rainfall exerts a positive effect, while temperature and relative humidity exert negative effects on cassava production. This indicates the sensitivity of cassava to climate change in the study area. Thus, increased and sustained production of cassava for household’s food security income would be attainable by designing programmes and policies geared toward reducing the effect of climate change.
