FERTILIZER MAINTENANCE NITROGEN IN VEGETATIVE DEVELOPMENT AND PRODUCTION OF PEACH

O trabalho foi conduzido na area experimental pertencente a Embrapa Clima Temperado, Pelotas-RS, entre os anos de 2012 e 2014. Os tratamentos foram compostos por tres genotipos (‘BRS Kampai’, ‘BRS Rubimel’ e ‘Selecao Cascata 805’) e tres doses de adubacao nitrogenada de manutencao (0, 100 e 200Kg N ha -1 ), avaliados num delineamento experimental em parcelas subdivididas. Teve como objetivo avaliar o efeito da adubacao nitrogenada de manutencao sobre desenvolvimento vegetativo e produtivo de pessegueiros cultivados em alta densidade de plantio. Nas condicoes de avaliacao do experimento foi possivel concluir que as doses de nitrogenio testadas nao influenciam no numero de frutos por planta e nem na massa medio dos frutos. No entanto estas influenciam diretamente na massa de ramos retirados durante a poda verde.
Mechanical and viscoelastic properties of glass-forming polymers in the bulk and thin films : molecular dynamics study of model systems

En nous concentrant sur les valeurs du module de cisaillement l’equilibre Geq pour le modele bien connu des polymeres vitrifiables (echantillionne par le biais de la MD), nous avons adresse la question generale de en quoi les proprietees mechaniques des couches mince differes de la phase volumique. Il a ete demontre que dans les deux cas Geq de maniere non ambigus separe l’etat fluide (Geq = 0) de l’etat vitreux (Geq > 0). Nous avons aussi insiste sur le fait que Geq pour la couche mince depend de lepaisseur du film h mais aussi de de la pression tangentielle qui est un resultante de la procedure de preparation de la couche mince
Three-Generation Study of Male Rats Gestationally Exposed to High Butterfat and Bisphenol A: Impaired Spermatogenesis, Penetrance with Reduced Severity

Gestational high butterfat (HFB) and/or endocrine disruptor exposure was previously found to disrupt spermatogenesis in adulthood. This study addresses the data gap in our knowledge regarding transgenerational transmission of the disruptive interaction between a high-fat diet and endocrine disruptor bisphenol A (BPA). F0 generation Sprague-Dawley rats were fed diets containing butterfat (10 kcal%) and high in butterfat (39 kcal%, HFB) with or without BPA (25 µg/kg body weight/day) during mating and pregnancy. Gestationally exposed F1-generation offspring from different litters were mated to produce F2 offspring, and similarly, F2-generation animals produced F3-generation offspring. One group of F3 male offspring was administered either testosterone plus estradiol-17β (T + E2) or sham via capsule implants from postnatal days 70 to 210. Another group was naturally aged to 18 months. Combination diets of HFB + BPA in F0 dams, but not single exposure to either, disrupted spermatogenesis in F3-generation adult males in both the T + E2-implanted group and the naturally aged group. CYP19A1 localization to the acrosome and estrogen receptor beta (ERbeta) localization to the nucleus were associated with impaired spermatogenesis. Finally, expression of methyl-CpG-binding domain-3 (MBD3) was consistently decreased in the HFB and HFB + BPA exposed F1 and F3 testes, suggesting an epigenetic component to this inheritance. However, the severe atrophy within testes present in F1 males was absent in F3 males. In conclusion, the HFB + BPA group demonstrated transgenerational inheritance of the impaired spermatogenesis phenotype, but severity was reduced in the F3 generation.
Effect of rGO–Fe2O3 nanocomposites fabricated in different solvents on the thermal decomposition properties of ammonium perchlorate

rGO–Fe2O3 composites were prepared using different solvents (distilled water, ethanol, N-methylpyrrolidone, ethyl acetate, n-butyl alcohol and N,N-dimethylformamide) via a simple solvothermal method and characterized by SEM, TEM, XRD, FT-IR, Raman and XPS techniques. Then, the catalytic action of rGO–Fe2O3 composites (prepared in different solvents), GO, rGO and pristine Fe2O3 on the thermal decomposition of ammonium perchlorate (AP) were studied using a TG-DSC instrument. DSC results showed that GO, rGO, pristine Fe2O3 and rGO–Fe2O3 composites could effectively promote the thermal decomposition of AP. Additionally, rGO–Fe2O3 fabricated in N,N-dimethylformamide (DMF) solvent possesses the best catalytic performance among the investigated materials. This result can be attributed to the better dispersibility of Fe2O3 nanoparticles on graphene oxide prepared in DMF solvent, which was confirmed by SEM and TEM imaging. The high temperature decomposition exothermic peak (HTP) and the apparent activation energy of AP are reduced by 119.6 °C and 173.3 kJ mol−1, respectively, in the presence of Fe2O3–rGO (DMF) composite.
The Biometric Vox System for the ASVspoof 2021 Challenge

This paper describes the systems developed by Biometric Vox for the ASVspoof 2021 challenge Logical Access (LA) and Physical Access (PA) tracks. The Logical Access track aims at detecting the use of speech synthesis or voice conversion techniques. In the case of the Physical Access track, the task is the detection of replayed speech. We experiment with different input features and neural network architectures. In particular, we propose a lightweight Time Delay Neural Network architecture and the use of Focal Loss as a way to handle class imbalance and emphasize hard-to-classify samples. Additionally, we explore the use of neural networks as embedding ex-tractors and propose a one-class Gaussian classiﬁer on top of these embeddings. Our ﬁnal system for the PA track obtains min-tDCF= 0 . 6658 and EER= 24 . 44% on the progress set and min-tDCF= 0 . 7462 and EER= 29 . 00% on the evaluation set. On the LA track, our best system obtains min-tDCF= 0 . 2371 and EER= 4 . 54% on the progress set and min-tDCF= 0 . 2747 and EER= 5 . 58% on the evaluation set.
Organizational Politics and Organizational Citizenship Behavior: Interaction and Analysis

Perceptions of organizational politics are an essential aspect of organizational life for its members because they impact different practices, which eventually affect employee efficiency. This article is explored the relationship between Organizational Politics (OP) and Organizational Citizenship Behavior (organizational citizenship behavior for organization (OCB-O) and organizational citizenship behavior for individuals (OCB-I). Survey data is gathered from 200 employees work in Jordanian public sector. Partial least square (PLS-SEM) is employed to test the research hypotheses. Outcomes uncovered that OP has a negative relationship with OCB-O and OCB-I. Accordingly, the current study recommends that governments abolish or restrict OP activities in their organizations as much as possible. Besides, the findings show that OP activities harmed public-sector employee behavior. The study's limitations and recommendations for future studies are also considered.
Unifloral Autumn Heather Honey from Indigenous Greek Erica manipuliflora Salisb.: SPME/GC-MS Characterization of the Volatile Fraction and Optimization of the Isolation Parameters

For long heather honey has been a special variety due to its unique organoleptic characteristics. This study aimed to characterize and optimize the isolation of the dominant volatile fraction of Greek autumn heather honey using solid-phase microextraction (SPME) followed by gas chromatography-mass spectrometry (GC-MS). The described approach pointed out 13 main volatile components more closely related to honey botanical origin, in terms of occurrence and relative abundance. These volatiles include phenolic compounds and norisoprenoids, with benzaldehyde, safranal and p-anisaldehyde present in higher amounts, while ethyl 4-methoxybenzoate is reported for the first time in honey. Then, an experimental design was developed based on five numeric factors and one categorical factor and evaluated the optimum conditions (temperature: 60 °C, equilibration time: 30 min extraction time: 15 min magnetic stirrer velocity: 100 rpm sample volume: 6 mL water: honey ratio: 1:3 (v/w)). Additionally, a validation test set reinforces the above methodology investigation. Honey is very complex and variable with respect to its volatile components given the high diversity of the floral source. As a result, customizing the isolation parameters for each honey is a good approach for streamlining the isolation volatile compounds. This study could provide a good basis for future recognition of monofloral autumn heather honey.
Understanding Sustainability Reporting in Non-Governmental Organisations: A Systematic Review of Reporting Practices, Drivers, Barriers and Paths for Future Research

NGOs are expected by their social mission not only to assess but to report on sustainability issues in response to the growing public awareness of the sustainability agendas. Since NGOs are globally renowned as watchdogs for advancing socio-economic development and sustainable societies, research on their efforts in this regard will help develop recommendations on how they can be better positioned as the watchdog. The purpose of this article is to review and assess the understanding of sustainability (reporting) in NGO literature as well as the barriers and drivers. The study investigates various practices of sustainability and identifies the drivers and barriers in sustainability reporting (SR). The authors reviewed 61 articles published between 2010 and 2020 on sustainability and assessed the strengths and weaknesses in the understanding of sustainability in literature as well as the reporting phenomenon in NGOs. The misconceptions in the definition of SR tend to weaken its relevance and applicability, and the reporting process is often focused on demonstrating the legitimacy of NGOs rather than improving their performance. As such, it provides more evidence in support of the need for a more holistic and all-inclusive definition that will aid regulation and enforcement. We also found that, although it is often assumed all NGOs share similar objectives, it is not always the case as there are as diverse objectives as there are numbers of NGOs and their reporting pattern varies in accordance with this diversity. The review makes a case for a more comprehensive definition of SR suitable for NGOs using four elements as well as providing suggestions for where research in this area might focus to enhance the overall body of knowledge. The study contributes to theory and practice by introducing new elements guiding the definition of SR in NGOs which supports accountability and proper functioning of a circular economy and promotes sustainable development.
The Effect of Transformational Leadership on Decision-Making Participation: Moderating Roles of Cognitive Styles

This study aims to examine the effect of transformational leadership style on decision-making participation and assess the moderating role of analytical and intuitive cognitive styles. Positivistic research philosophy and quantitative methodology utilising self-report questionnaires was used in collecting data from 196 teachers of six selected educational organisations in Selangor, Malaysia. A descriptive survey design was selected, where information was collected through self-report questionnaires which were administered to the subjects by the researcher. Hierarchical regression was employed to measure the relationship between transformational leadership style and decision making participation, and subsequently evaluate the role of analytical and intuitive cognitive styles as moderators within this relationship. Findings from the study indicate that there was no significant relationship between transformational leadership style and decision making participation. Findings from the study indicate that analytical cognitive style moderates the relationship between transformational leadership style and decision making participation. Transformational leadership style with intuitive cognitive style also demonstrated a positive effect on decision-making participation, according to the value of the coefficient. Practically, this research is valuable to cognitive styles could influence their leadership role towards decision-making participation. Theoretically this study contributes to more understanding on decision-making participation abilities, by stressing the use of selected cognitive and leadership styles.
Interplay of Active Stress and Driven Flow in Self-Assembled, Tumbling Active Nematics

Lyotropic chromonic liquid crystals (LCLCs) are a special type of hierarchical material in which self-assembled molecular aggregates are responsible for the formation of liquid crystal phases. Thanks to its unusual material properties and bio compatibility, it has found wide applications including the formation of active nematic liquid crystals. Recent experiments have uncovered tumbling character of certain LCLCs. However, how tumbling behavior modifies structure and flow in driven and active nematics is poorly understood. Here, we rely on continuum simulation to study the interplay of extensile active stress and externally driven flow in a flow-tumbling nematic with a low twist modulus to mimic nematic LCLCs. We find that a spontaneous transverse flow can be developed in a flow-tumbling active nematic confined to a hybrid alignment cell when it is in log-rolling mode at sufficiently high activities. The orientation of the total spontaneous flow is tunable by tuning the active stress. We further show that activity can suppress pressure-driven flow of a flow-tumbling nematic in a planar-anchoring cell but can also promote a transition of the director field under a pressure gradient in a homeotropic-anchoring cell. Remarkably, we demonstrate that the frequency of unsteady director dynamics in a tumbling nematic under Couette flow is invariant against active stress when below a threshold activity but exhibits a discontinuous increase when above the threshold at which a complex, periodic spatiotemporal director pattern emerges. Taken together, our simulations reveal qualitative differences between flow-tumbling and flow-aligning active nematics and suggest potential applications of tumbling nematics in microfluidics.
Étude du phénomène de compression de spin dans un condensat de Bose-Einstein piégé sur microcircuit

Dans ce manuscrit, nous presentons une etude experimentale du phenomene de compression de spin dans un condensat de Bose-Einstein de $^{87}Rb$, resultant d'une interaction non-lineaire provenant de collisions entre les deux etats internes $|F=1, m_F=-1>$ et $|F=2, m_F=1>$ de l'etat fondamental $5^2S_{1/2}$. Les atomes sont refroidis dans un piege magneto-optique, puis pieges magnetiquement a l'aide de notre puce a atomes jouant le role de parois superieure pour notre enceinte a vide. La puce est aussi utilisee pour emettre le champ radiofrequence permettant le refroidissement evaporatif conduisant a la condensation de Bose-Einstein, ainsi que le champ micro-onde qui realise le transfert coherent des atomes d'un etat interne a un autre.L'ensemble atomique est decrit par le Hamiltonien "textit{one-axis-twisting}" qui contient un terme quadratique en la composante selon l'axe $z$ du vecteur de spin atomique $S_z$. L'amplitude de cette interaction non-lineaire, initialement tres faible, depend des longueurs de diffusion des etats internes consideres, et peut etre grandement augmentee en reduisant le recouvrement des fonctions d'onde. C'est pourquoi le systeme est place dans une configuration particuliere (grand nombre d'atomes et piege anisotrope de type "cigare") pour laquelle les deux etats vont alterner des phases de separation et recombinaison spatiale. L'impact de cette dynamique spatiale sur l'interaction de champ moyen et la coherence du systeme est analyse experimentalement a travers l'etude du contraste et de la frequence centrale d'un interferometre de Ramsey.Theoriquement, lorsque les deux etats sont separes, la distribution de spin se transforme d'une distribution circulaire regie par le bruit de projection quantique, en une ellipse dont le petit axe est inferieur a la limite quantique standard, sous l'effet de l'interaction en $S_z^2$. Ceci est verifie experimentalement en realisant la tomographie de l'etat atomique au moment ou les deux modes internes se recombinent. Un parametre de compression de spin $xi^2 = -1.3 pm 0.4$ dB est ainsi obtenu pour 5000 atomes et un contraste de 90%. L'etude des differentes sources d'instabilites a permis d'identifier les pertes atomiques comme limitation principale de la compression de spin et du contraste de l'interferometre.Ce travail s'inscrit dans le contexte de la metrologie quantique et represente un pas vers la production d'etats comprimes en spin permettant la realisation d'interferometres atomiques fonctionnant sous la limite quantique standard. La question de la coherence d'un condensat bimodal soumis a de nombreuses collisions elastiques et inelastiques est aussi adressee.
Evaluation of Electrospinning Process Parameters of Poly Lactic-Co-Glycolic Acid and Hydroxyapatite Nanocomposite Nanofibrous Scaffolds

Electrospinning recognized as a simple and inexpensive process for producing continuous polymeric nanofibers with diameters ranging from several micrometers down to tens of nanometers. In this study, an electrospun nanofibrous scaffolds based on lactic-co-glycolic acid (PLGA) and nanohydroxyapatite (nano-HA) was developed. The fiber morphology and mean fiber diameter of prepared nanofibers were investigated by scanning electron microscopy. FTIR analysis demonstrated that there were strong intramolecular interactions between the molecules of PLGA and nano-HA. A more systematic understanding of process parameters was obtained and a quantitative relationship between electrospinning parameters and average fiber diameter was established by using response surface methodology. A response surface function was empirically determined by central composite design using fiber diameter as an observed response and the electrospinning parameters such as concentration, distance, applied voltage, temperature and flow rate as variables. The regression coefficient of the model was found to be 0.938. The predicted fiber diameter was in good agreement with the experimental result. PLGA/nano-HA nanofibrous scaffolds could be good candidates for tissue engineering applications.
Consumers’ willingness to consume cassava leaves as a leafy vegetable in the Kumasi Metropolis, Ghana

This study employs the logit model to assess the determinants of consumers’ willingness to consume cassava leaves as a leafy vegetable in the Kumasi Metropolis of Ghana. A multistage sampling technique was used to select 180 respondents for the study. The study found that majority (76%) of the respondents had no knowledge of the nutritional value of cassava leaves, though they had consumed the product before. The empirical results showed that socioeconomic characteristics of respondents such as age, sex, household size and monthly income, as well as their perceptions on the attributes and use of cassava leaves as food have significant influence on willingness to consume cassava leaves as a leafy vegetable. There is the need to provide information on the nutritional benefits of cassava leaves to facilitate decision-making on its utilisation/consumption. Programmes aimed at promoting the consumption of cassava leaves should consider the significant variables that have influence on the consumption of the product.
Layered Na2Mn3O7 as a 3.1 V Insertion Material for Li-Ion Batteries

Exploring Mn-based battery insertion materials, layered Na2Mn3O7 was synthesized via single pot solid-state method. Rietveld analysis confirmed the formation of triclinic structured Na2Mn3O7 with P-1 symmetry. With no further optimization, the as-synthesized Na2Mn3O7 was found to be an efficient host for Li+ (de)intercalation. Na2Mn3O7 delivered a discharge capacity of ∼160 mA h g–1 by altering the redox couple Mn(IV)/Mn(III) with a nominal voltage of 3.12 V (vs Li/Li+). Interestingly, the first discharge of pristine Na2Mn3O7 led to the formation of LixNa2Mn3O7 (2 < x < 3) having completely different phase similar to the LiCoO2 structure. Lithiation triggered phase transformation from triclinic (P-1) to trigonal (R-3m) structure. This electrochemically reformed structure imparts stability to [Mn3O7]−2∞ building layers, preventing irreversible capacity loss. Underlying a single-phase (solid-solution) redox mechanism, Na2Mn3O7 acts as a robust cathode material for Li-ion batteries.
Charismatic Tour-Guiding: Scale Development and Validation

Charismatic leadership has been conceptualized as a signaling process whereby a leader influences followers to achieve effective management. Although there have been many studies on charismatic leadership, no scale exists to measure tour leaders’ charismatic guiding. Thus, the purpose of this study was to develop a valid and reliable charismatic-guiding scale for tour leaders, from the perspectives of both tour leaders and tour members. Through a rigorous development process, the study’s 20-item, 4-dimensional tour leaders’ charismatic-guiding scale was proven to be valid and reliable. The novel scale may function as a tool for tour leaders to measure their charismatic guiding as well as for travel agencies in their assignment of tour leaders. This study applied charismatic leadership theory to tourism, furthering knowledge of charismatic guiding in tour leaders and establishing a foundation for future theoretical development.
Effect of Crianza Positiva e-messaging program on adult–child language interactions

We assess the effects of the Crianza Positiva text and audio e-messaging program on caregiver–child language interaction patterns. The program is a six-month-long intervention for families with children aged 0–2 aimed at strengthening parental competences. Its design exploits behavioral tools such as reminders, suggestions of action, and messages of encouragement to reinforce and sustain positive parenting practices. Families in 24 early childhood centers in Uruguay that completed an eight-week workshop were randomized into receiving or not receiving mobile messages. After the program, we videotaped 10-minute sessions of free play between the caregiver and the child, and decoded language patterns using automated techniques. The intervention was successful at improving the quality of parental vocalizations, as measured by the parent's pitch range. We also found suggestive evidence of increases in the duration of adult vocalizations. The results are consistent with more frequent parental self-reported involvement in reading, telling stories, and describing things to the child. Regarding the child, we find a nonrobust decrease in the duration of vocalizations, which we attribute to a crowding-out effect by the caregiver in the context of a fixed 10-minute suggested activity and a more proactive parental role.
