Path Analysis for Maize (Zea mays) Silage Cerrado-Amazon Ecotone

— The management of nitrogen fertilization is of paramount importance for the increase of corn silage productivity, by directly participating in the processes of cell division and expansion.It is extremely important to identify the characteristics that are associated with the responsiveness of the use of nitrogen fertilization.Therefore, this study aims to identify the characteristics that most influence the total weight in maize silage production.Two trials were conducted, one with low nitrogen dosage (0 kg ha -1 of N in cover) and the other with a high dosage (120 kg ha -1 of N in cover), performed in the harvest 2017/18, in Sítio Vitória, in the municipalityof Santa Maria das Barreiras, State of Pará, located in the ecotone Cerrado-Amazon. The experimental design used was randomized blocks with eleven treatments and three replications.The treatments used were BRS 3046, M274, AG 8088, ANHEMBI, PR 27D28, P33-16, P32-11, P29-M12, P36-19, P40-8, and AG 1051. The base fertilization was performed in the groove manually supplying the needs of chemical and physical analysis. Whole plants of the useful plot were harvested and the characteristics were measured forplant height, insertion height of the first ear, culm diameter, the diameter of the ear, weight of the stem leaf, ear weight, and total plant weight. Track and variance analyses were performed through the Genes computer program. Variance analysis was performed for Low and High N, and track analyses for low N, high N, and average values conditions.
MDN: A Deep Maximization-Differentiation Network for Spatio-Temporal Depression Detection

Deep learning (DL) models have been successfully applied in video-based affective computing, allowing, for instance, to recognize emotions and mood, or to estimate the intensity of pain or stress of individuals based on their facial expressions. Despite the recent advances with state-of-the-art DL models for spatio-temporal recognition of facial expressions associated with depressive behaviour, some key challenges remain in the cost-effective application of 3D-CNNs: (1) 3D convolutions usually employ structures with fixed temporal depth that decreases the potential to extract discriminative representations due to the usually small difference of spatio-temporal variations along different depression levels; and (2) the computational complexity of these models with consequent susceptibility to overfitting. To address these challenges, we propose a novel DL architecture called the Maximization and Differentiation Network (MDN) in order to effectively represent facial expression variations that are relevant for depression assessment. The MDN, operating without 3D convolutions, explores multiscale temporal information using a maximization block that captures smooth facial variations and a difference block that encodes sudden facial variations. Extensive experiments using our proposed MDN with models with 100 and 152 layers result in improved performance while reducing the number of parameters by more than <inline-formula><tex-math notation="LaTeX">$3\times$</tex-math><alternatives><mml:math><mml:mrow><mml:mn>3</mml:mn><mml:mo>×</mml:mo></mml:mrow></mml:math><inline-graphic xlink:href="carneirodemelo-ieq1-3072579.gif"/></alternatives></inline-formula> when compared with 3D ResNet models. Our model also outperforms other 3D models and achieves state-of-the-art results for depression detection. Code available at: <uri>https://github.com/wheidima/MDN</uri>.
FORMULATION AND EVALUATION OF VALSARTAN FAST DISINTEGRATING TABLETS BY VACUUM DRYING TECHNIQUE

ABSTRACT Objective: The main objective present research work an attempt has been made to prepare fast dissolving tablets of Valsartan by using vacuum drying technique. Camphor, Urea and Menthol are used as a sublimating agent. Valsartan is an oral antihypertensive agent, with problems of variable bioavailability and bioequivalence related to its poor water solubility. Valsartan is an angiotensin II type 1 receptor antagonist indicated in the treatment of hypertension. Methods: The prepared tablets Valsartan fast dissolving tablets were evaluated for various parameters like weight variation, hardness, friability, disintegration time, drug content, water absorption ratio, wetting time, in- vitro drug release, FTIR, DSC studies and short term stability studies. The blend was examined for the pre-compressional and post-compressional parameter. Results and Discussions: The values of pre-compression parameters evaluated were within prescribed limits and indicated good free flowing property. All the post-compressional parameter are evaluated were prescribed limits and results were within IP acceptable limits. Based on the invitro disintegration time and dissolution studies formulations SC2 and SC3 were found to be promising and showed a disintegration time of 24 sec and 16 sec respectively. Formulation SC3 containing camphor showed highest drug release 99.4% within 10 min. IR spectral analysis and DSC study showed that there was no drug interaction with formulation additives of the tablet as there is no variation and shift in the position of characteristic absorption bands it can be justified there is no interaction between drug and polymer. Short term stability studies on the formulations indicated that there are no significant change in hardness, friability, drug content and in-vitro drug release (p<0.05). Conclusion: The results concluded that fast dissolving tablets of Valsartan showing enhanced dissolution may lead to improved bioavailability and effective therapy by using sublimation method. Keywords: Fast dissolving tablet, Valsartan, Crospovidone, Camphor, Urea, Disintegration time.
Majority Carrier Type Control of Cobalt Iron Sulfide (CoxFe1–xS2) Pyrite Nanocrystals

We report the colloidal synthesis, characterization, and electronic property control of compositionally varied CoxFe1–xS2 cubic pyrite nanocrystals (NCs) and thin films formed from solution. Using drop-cast NC thin films, we demonstrate the relationship between the material composition and the majority carrier type of the nanocrystalline thin films. Measurements of the majority carrier type as a function of NC composition indicate that CoxFe1–xS2 NC thin films change from p-type to n-type between x = 0.16 and x = 0.21. Additional characterization to confirm the crystallinity, composition, size, and shape was performed using powder X-ray diffraction, Raman spectroscopy, energy dispersive X-ray spectroscopy, and scanning electron microscopy. The observed n-type behavior which accompanies the substitution of Co for Fe in these cubic pyrite nanostructures agrees with previous reports of n-type behavior occurring at even very low concentration Co doping of iron pyrite. The ability to prepare n- or p-type pyrit.
Sequential Linking To Control Growth of a Surface Covalent Organic Framework

We report on formation of a new surface covalent organic framework (SCOF) based on a sequential polymerization in two stages. The bifunctional precursor used, p-bromo-benzene boronic acid (BBBA), was vapor deposited in ultra-high-vacuum conditions on a Au(111) surface. In a first step the boronic acid moieties reacted to form trimers linked by covalent boroxine rings. In a second step, an Ullmann coupling reaction was thermally activated to form C–C bonds between the trimers, leading to the final polymeric network. By this procedure the growth mechanism was optimized and the polymerization reaction yield could approach 100%. A well-extended network was obtained, differing from the ideal honeycomb-like network by a substantial number of nonhexagonal pores, which are intrinsic defects to the polymer structure. A comparison of the two competing reactions provides new insights into the complex mechanisms governing growth of two-dimensional covalent networks.
Entropy based Software Reliability Growth Modelling for Open Source Software Evolution

: During Open Source Software (OSS) development, users submit "new features (NFs)", "feature improvements (IMPs)" and bugs to fix. A proportion of these issues get fixed before the next software release. During the introduction of NFs and IMPs, the source code files change. A proportion of these source code changes may result in generation of bugs. We have developed calendar time and entropy-dependent mathematical models to represent the growth of OSS based on the rate at which NFs are added, IMPs are added, and bugs introduction rate.The empirical validation has been conducted on five products, namely "Avro, Pig, Hive, jUDDI and Whirr" of the Apache open source project. We compared the proposed models with eminent reliability growth models, Goel and Okumoto (1979) and Yamada et al. (1983) and found that the proposed models exhibit better goodness of fit.
Clinical value of oblique lateral lumbar interbody fusion combined with posterior navigation and long segment internal fixation in the treatment of degenerative scoliosis

Background ：To assess the short-term clinical outcomes of oblique lateral lumbar interbody fusion (OLIF) combined with multiple level fixation with the guidance of posterior "O" arm CT navigation for degenerative scoliosis. Methods ：A total of 15 patients (3 males and 12 females; average age: 62.2±5.3 years) with degenerative scoliosis were enrolled in our study. All patients were treated with OLIF combined with posterior "O" arm CT navigation and long segment (T 10 -L 5 ) internal fixation during Apr. 2016 and Dec. 2017. Collected perioperative data included surgery time, blood loss, excellent rate of intraoperative pedicle screw. Coronal Cobb angle, lumbar lordosis (LL), intervertebral space height, sagittal balance (SVA) were measured by plain radiograph. Accuracy of pedicle screw placement and intervertebral fusion was investigated with postoperative CT. Visual analogue scale (VAS) and Oswestry disability index (ODI) were used to evaluate the clinical efficacy of surgery. Results ： All patients were followed for 12-25 months (16.5±5.3 months). The OLIF operation time was (98.7±16.8) min, and the blood loss was (50.2±10.7) ml. The posterior "O" arm CT-navigated long segment internal fixation was (101.5 ± 23.4) min, and the blood loss was (63.1 ± 19.7) ml. The total operation time was (200.2±40.2) min, and the blood loss was (113.3±30.4) ml. Coronal Cobb angle, LL, intervertebral space height, SVA, VAS, ODI at the last follow-up were 5.5°± 3.1°, 39.3°± 9.1°, (10.9±1.2) mm, (25.1±10.9) mm, (1.3± 0.8)and(15.8±4.5)%, respectively, showing statistically significant differences ( P <0.05). The "O" arm CT navigation has 240 nails, and the excellent rate of three-dimensional scanning of the "O" arm during surgery is 96%. Lumbar CT showed lumbar fusion at the 6-month postoperative period. Conclusion ： The short-term clinical outcomes of oblique lateral lumbar interbody fusion combined with posterior "O" arm CT-navigated long segment internal fixation for degenerative scoliosis are satisfactory, with advantages like minimal invasiveness, accurate navigation, high bone fusion rate and few complications.

Comparison of percutaneous vertebroplasty with a side-hole push rod and conventional percutaneous vertebroplasty for the treatment of OVCFs

ObjectiveThe aim of this study was to compare the clinical efficacy of percutaneous vertebroplasty with a side-hole push rod (modified PVP) and conventional PVP in treating osteoporotic vertebral compression fractures (OVCFs). Materials and methodsThis study included 69 patients with 1-level OVCFs. Perioperative indicators, including the operative time, cement injection volume, cement leakage rate, and distribution of cement in the fractured area, were analysed. The visual analogue scale (VAS) and Oswestry disability index (ODI) were administered pre- and postoperatively.ResultsNo significant differences were observed in the operative time or cement injection volume between the two groups (p > 0.05). The total diffusion score of bone cement in the PVP group was significantly lower than that in the modified PVP group (p < 0.05). Compared with the conventional PVP group, the modified PVP group had a significantly lower VAS score at 3 days postoperatively (p < 0.05). There were no differences in the VAS or ODI scores between the two groups at the last follow-up (p > 0.05). Bone cement leakage was observed in 15 cases in the conventional PVP group (15/32) and in 9 cases in the modified PVP group (9/37). ConclusionThe modified version of PVP provides sufficient cement to fill the fractured area and is associated with a lower incidence of cement leakage and undesired postoperative results than is conventional PVP, indicating that modified PVP is a safe and effective new technique for the treatment of OVCFs.
WiDE: WiFi Distance Based Group Profiling Via Machine Learning

We develop WiDE, a WiFi-distance estimation based group profiling system using LightGBM. Given the uploaded WiFi information by users, WiDE can automatically learn powerful hidden features from the proposed features for between-user distance estimation, and infer group membership with the estimated distance. For each group, WiDE classifies the mobility level, and recognizes the group structure by applying the multi-dimensional scaling technique on the matrix of distance between pairwise users within the same group. We first validate the performance of between-user distance estimation via conducting extensive experiments in a three-floor campus building and a shopping center, and the results show that WiDE outperforms other machine learning based approaches for between-user distance estimation, with the average absolute error (AAE) of 0.69m and 1.14m for the campus building and shopping center, respectively, and the corridor identification accuracy for the campus building is over 99 percent. In addition, the experiments in the shopping center show that our approach can accurately detect groups, classify group mobility into fine-grained level and recognize the group structure.
On the compressible Navier-Stokes equations in the whole space: From non-isentropic flow to isentropic flow

The present work aims at the mathematical derivation of the equations for the isentropic flow from those for the non-isentropic flow for perfect gases in the whole space. Suppose that the following things hold for the entropy equation: (1). both conduction of heat and its generation by dissipation of mechanical energy are sufficiently weak(with the order of \begin{document}$ \varepsilon $\end{document} ); (2). initially the entropy \begin{document}$ S^{N}_ \varepsilon $\end{document} is around a constant \begin{document}$ c_S $\end{document} , that is, \begin{document}$ S^{N}_ \varepsilon |_{t = 0} = c_S+O( \varepsilon ) $\end{document} . Then the non-isentropic compressible Navier-Stokes equations admit a unique and global solution \begin{document}$ ( \rho^{N}_ \varepsilon , \, \boldsymbol{u}^{N}_ \varepsilon , \, S^{N}_ \varepsilon ) $\end{document} with the initial data \begin{document}$ ( \rho_0, \, \boldsymbol{u}_0, \, c_S+ \varepsilon S_0) $\end{document} , which is a perturbation of the equilibrium \begin{document}$ (1, \boldsymbol{0}, c_S) $\end{document} . Moreover, \begin{document}$ ( \rho^{N}_ \varepsilon , u^{N}_ \varepsilon ) $\end{document} can be approximated by \begin{document}$ ( \rho^{I}, \, u^{I}) $\end{document} , the solution to the associated isentropic compressible Navier-Stokes equations equipped with the initial data \begin{document}$ ( \rho_0, \, \boldsymbol{u}_0) $\end{document} , in the sense that \begin{document}$ \begin{eqnarray*} ( \rho^{N}_ \varepsilon (t), \, \boldsymbol{u}^{N}_ \varepsilon (t)) = ( \rho^{I}(t), \, \boldsymbol{u}^{I}(t))+O(\epsilon), \end{eqnarray*} $\end{document} which holds globally in the so-called critical Besov spaces for the compressible Navier-Stokes equations.
Improving the Use of Healthcare Resources in Canadian Hospitals: The Impact of a Reintegration Unit in Expanding Acute Care Capacity and Resource Use in Sunnybrook Health Sciences Centre

Background: Alternate level of care (ALC) patients are those who reside in acute hospital beds but can be managed in non-hospital settings. They contribute to high occupancy levels in Canadian hospitals. Between 2017-18, Ontario spent 1.1 billion dollars on hospitalized patients waiting for alternate level of care (ALC) beds. To improve value for care, Ontario Ministry of Health (MOHLTC) invested into reintegration units which are designed to transfer ALC patients out of hospital and transition them back into the community or long-term care (LTC). Given today’s healthcare budget pressures, it is unclear if reactivation units are feasible. In 2018, the MOHLTC funded a reintegration unit, Pine Villa with an operational partner, Sunnybrook Hospital and community service providers (SPRINT Senior Care, LOFT) in Toronto, Ontario. The objective was to determine averted costs for ALC-patients and impact on Sunnybrook patient flow-through if ALC-patient Pine Villa transfers occurred on the day of ALC readiness. Methods: Retrospective, observational analysis of Sunnybrook ALC-patients discharged to Pine Villa between January 9, 2018 to February 4, 2019. From the healthcare payer’s perspective (MOHTLC), cost analysis was modelled for ALC patients designated for 1) LTC and 2) home with supports. Avoided costs at time of ALC readiness were determined by case-costing. Averted hospital ALC days were established. Results: If ALC patients were transferred to Pine Villa at time of ALC readiness for LTC, the healthcare system could have averted 5.4 million dollars from Sunnybrook. If the patients were transferred for home, 2.3 million dollars could have been averted. Both models increased acute Sunnybrook Hospital capacity by 34 beds. Conclusion: There is a business case supporting reintegration units if ALC-patients are discharged from the hospital on the day of ALC-readiness.
A Dedicated English Portfolio for a Bilingual Primary School: A Project-in-Progress to Address the Transition Challenge and Augment the Agency of Learners at a Bilingual Primary School (and Other Primary Schools)

A bilingual primary school has initiated a project to address the “transition challenge” the children at the school, all of whom have bilingual classes from the start of Year One on, will face in the subject English when they go to secondary school. Working with researchers, a teacher from the school is developing a flexible, easily adaptable self-assessment portfolio that learners are able to present at secondary school so that their new English teachers can build on what the children have learnt and can do. This contribution relates some of the decisions and experiences this project-in-progress entailed in its first implementation with children in Years One and Two. For example, the project team observed informally that working with the portfolio and reflecting on their learning process and progress promotes the children’s agency and autonomy. While the portfolio is a practical instrument initiated at grassroots level, the data gathered are undoubtedly of interest to researchers and provide evidence of the benefits of starting English in Year One, and of an inclusive, across-the-board, immersive bilingual policy.
Happiness, Wellbeing, and Mental Health in Bhutanese Higher Education: Exploring Student and Staff Experiences and Perceptions within a Framework of Gross National Happiness

Bhutan is a country known for happiness. In the 1970s, the Fourth Druk Gyalpo [Dragon King] of Bhutan established the development philosophy of Gross National Happiness (GNH). However, using ‘happiness’ as a measurement of social and economic development does not mean that all Bhutanese are ‘happy’ themselves. Schools – including higher education – can be stressful places in Bhutan, and there is little support or resources for the mental health and wellbeing needs of students. In this article, we explore the experiences and perceptions of both students and staff across the Royal University of Bhutan in regard to wellbeing and mental health. In all, there were over 1,700 respondents to our survey. We explore the results of the survey through an Educational Values Evaluation and Design (EVED) framework to understand the complex factors that both enable and challenge GNH as a value in higher education. The results show that while many students view their happiness and wellbeing as positive overall, there are still a significant amount that experience depression, stress, social difficulties, and other forms of distress. In comparison to college staff perception of student’s mental health and wellbeing, the students are more positive about their own wellbeing than the staff.
Environmentally benign synthesis methods of zero valent iron nanoparticles

Zero-valent iron nanoparticles (nZVI) have already proven their efficacy in the reductive disposal of a wide array of environmental contaminants in numerous laboratory and field trials. However, their large-scale application in remediation applications is hindered by the high costs and the legislative issues associated with the conventional nZVI synthesis method that relies on NaBH4 as a reducing agent. The two common strategies to replace sodium borohydride are (i) totally “green” nZVI syntheses based on plant extracts, and (ii) “semigreen” nZVI synthesis based on less toxic and more cost-effective industrial chemical reducing agents. In this paper we present a comparative evaluation of green and semigreen synthesis methods. The former utilized coffee, green tea, and Virginia creeper (Parthenocissus tricuspidata) leave extracts, the latters were based on sodium dithionite and sodium borohydride. nZVI synthesis was done in untreated tap water at room temperature to reduce the environmental footprint of th.
THE INFLUENCE OF ENTREPRENEURIAL PASSION AND CREATIVITY ON ENTREPRENEURIAL INTENTIONS

ABSTRACT Purpose: This study aims to analyze the influence of entrepreneurial passion and creativity on entrepreneurial intent. It also examines the mediating role of entrepreneurial self-efficacy between the personal/cognitive variable and entrepreneurial intention. Originality/value: By stressing the importance of cognitive and emotional variables that may influence entrepreneurial intentions among university students (such as creativity and entrepreneurial passion), this study shows the important role that universities have in the development of entrepreneurial intent. According to the Social Cognitive Theory (SCT), the environment influences individual behavior and, therefore, universities should encourage an entrepreneurial environment, enabling the creation of new jobs and companies. Design/methodology/approach: Data were collected through a survey with business and technology students from a Brazilian university. In total, 338 valid responses were obtained, which were analyzed through structural equation modeling. The data were collected in a cross-sectional manner and by a stratified and non-probability sampling method. To address the research hypothesis and to attain the objectives of the study, all constructs were adapted from relevant literature in the field of entrepreneurship. The structural model was examined in relation to the model fit, which enabled the hypothesis to be tested. Findings: Results showed both a direct and indirect positive relationship between entrepreneurial passion on entrepreneurial intention. Regarding the creativity factor, results indicated only an indirect effect of creativity on entrepreneurial intention, this relationship being mediated through entrepreneurial self-efficacy. No significant differences were found in the model regarding age, gender, graduation program, entrepreneurial family background, role models or family income.
