Authors: Siregar Parpen
Published: May 2020

A research was conducted with aims (1) to identify adaptation mechanisms of new soybean genotypes  in utilizing limited P from acid mineral soil: through carbon translocation to root and through absorption of specific P, and (2) to describe the respond of soybean genotype to P fertilization. Treatments, including soybean genotypes (Slamet, 19BE, and 25EC) and P fertilization (0 and 400 mg P kg-1 in form of KH2PO4) were factorially arranged in a Completely Randomized Design with four replications. Soybean was planted in a green house using double pot system. The upper pot was filled with a mixture of sterile soil and volcano sand, and lower pot with non sterilized soil. The evaluation was performed at the end vegetative growth phase (R1). Evaluated variables were dry weight of shoot, root, and plant total, alkaline phosphatase activity, number of nodules, N and P absorption, quality specific P index. Data variation was analyzed by using F-test with degree of fredoom α = 5% and differences among treatments were separated by using Duncan Multiple Range Test (DMRT). The results showed that soybean genotype had different mechanism in using limited P from acid mineral soil. Old genotype (Slamet) had mechanism through increasing alkaline phosphatase and absorption of specific P (P-Al, P-Fe dan P occluded). Genotype 19BE had mechanism through translocation of carbon to root or decreasing of shoot-root ratio; specific P absortion (P-Al dan P-Fe) was limited. Genotype 25EC had only decreased shoot-root ratio and P-Fe absortion mechanism. Fertilization with high P (400 mg kg-1) increased biomass production, number of root nodules, absortion N and P nutrients; however it decreased absorption alkaline-phosphatase activity at soybean rhizosphere at 35 day after planting. Fertilizing high dosage P created biopriming by decreasing the qualtity specific P on soil under 19BE and 25EC genotypes.Keywords : adaptation mechanism, soybean genotypes, acid soil, P acquisition

Authors: Arshad Muhammad , Furqan Yaqub Pannu  , Bilal Ahmad  , Salman Khalid  , Ahmad Kamran  , Faryal Zafar
Published: May 2020

Background: Rheumatic heart disease has a strong association with mitral valve stenosis. Atrial fibrillation is one of the most common complications of this condition and is a poor prognostic factor. Early detection and prompt management of atrial fibrillation can help to improve the quality of life and increase the life expectancy of the patients. We carried out this study to investigate the significance of left atrial volumetric changes in mitral stenosis and its correlation with atrial fibrillation.
Methodology: We audited the data of 60 patients of rheumatic heart disease who had mitral valve stenosis. The patients were randomized into atrial fibrillation (Group A) and normal sinus rhythm (Group B). We conducted this cross-sectional analytical study at Cardiology Department, Mayo Hospital, Lahore, from 1st February 2017 to 31st January 2018. We only included those patients who consented to be a part of this study and fulfilled our predefined inclusion criteria. Left atrial volume was measured by prolate ellipse method and biplane methods on echocardiography. The Data was analyzed on SPSS v20.
Results: Sixty patients were included in the study. Among the subjects, thirty-six (60%) were males, and twenty-four (40%) were females. Atrial fibrillation was noted in 43.33% of the patients of mitral valve stenosis. There was a marked difference in the mean volume of the left atrium among the two groups. We observed that the mean area of the mitral valve for Group A patients was larger than that of patients in Group B. Our study showed an inverse correlation between left atrial volume and mitral valve area among Group A patients.
Conclusion: Patients of mitral stenosis are at an increased risk of developing atrial fibrillation if the left atrial volume is increasing. All patients with mitral stenosis should have routine echocardiography & measurement of left atrial volumes, so that proper treatment can be started if the left atrial volume is increasing, to prevent atrial fibrillation.
Does the EU's Drive for Private Enforcement of Competition Law Have a Coherent Purpose?
Authors: Stephan Andreas
Published: May 2020

The Competition Laws of the European Union (‘EU’) have been a major influence on countless jurisdictions around the world, but their strength as a public enforcement regime have always contrasted with a perceived absence of private enforcement. Private parties cannot bring an action for damages or injunctive relief before EU courts. They can only make a complaint to the European Commission or National Competition Authority, to investigate an infringement of competition law, on their behalf. Therefore, a party’s ability to recover damages falls on the national tort and civil liability rules of each Member State. Although most European legal systems can broadly be described as belonging to the civil law tradition, there are significant differences in procedure and legal culture when it comes to recovering damages. It is also important to remember that the EU has continued to grow in the last fifteen years, with the accession of ten new Member States in 2004, and a further three between 2007 and 2013. These include states that have made a rapid transition from centrally planned economies and Communist-era legal systems.

We construct a model of Hα emitters (HAEs) based on a semianalytic galaxy formation model, the New Numerical Galaxy Catalog (ν
2GC). In this paper, we report our estimate for the field variance of the HAE distribution. By calculating the Hα luminosity from the star formation rate of galaxies, our model well reproduces the observed Hα luminosity function (LF) at z = 0.4. The large volume of the ν
2GC makes it possible to examine the spatial distribution of HAEs over a region of (411.8 Mpc)3 in the comoving scale. The surface number density of z = 0.4 HAEs with

erg s−1 is 308.9 deg−2. We have confirmed that the HAE is a useful tracer for the large-scale structure of the universe because of their significant overdensity (>5σ) at clusters and the filamentary structures. The Hα LFs within a survey area of ∼2 deg2 (typical for previous observational studies) show a significant field variance up to ∼1 dex. Based on our model, one can estimate the variance on the Hα LFs within given survey areas.
A Spectroscopic Method Based on the Shapes of Nuclear Deexcitation γ-Ray Lines in Solar Flares
Authors: Chen Wei , Gan W. Q.
Published: May 2020

The deexcitation γ-ray lines in solar flares result from energetic ions (e.g., protons, α-particles) interacting with the ambient nuclei in the solar atmosphere. The centroid and width of lines contain a wealth of information on the directionality, composition, and spectra of energetic ions as well as properties of the interaction sites. New calculations for the deexcitation γ-ray line shape analysis were done to study the properties of these ions. We calculate the shapes of the most intense deexcitation γ-ray lines in the solar flares, including the 12C 4.439 MeV, 16O 6.129 MeV, 24Mg 1.369 MeV, and 28Si 1.779 MeV lines, and explore the profiles of these line shapes as a function of the accelerated ion’s energy spectra and composition, as well as the heliocentric angle of flare location. The merits of deexcitation γ-ray line shape analysis include (1) only a relatively small number of parameters being required in the fitting process and (2) the characteristics of accelerated ions with joint multi-line shape analysis being well constrained. We conclude that the measurement of the width and centroid of lines is an effective method for determining the properties of flare-accelerated ions.

Published: May 2020

A deep learning network, long short-term memory (LSTM), is used to predict whether an active region (AR) will produce a flare of class Γ in the next 24 hr. We consider Γ to be ≥M (strong flare), ≥C (medium flare), and ≥A (any flare) class. The essence of using LSTM, which is a recurrent neural network, is its ability to capture temporal information on the data samples. The input features are time sequences of 20 magnetic parameters from the space weather Helioseismic and Magnetic Imager AR patches. We analyze ARs from 2010 June to 2018 December and their associated flares identified in the Geostationary Operational Environmental Satellite X-ray flare catalogs. Our results produce skill scores consistent with recently published results using LSTMs and are better than the previous results using a single time input. The skill scores from the model show statistically significant variation when different years of data are chosen for training and testing. In particular, 2015–2018 have better true skill statistic and Heidke skill scores for predicting ≥C medium flares than 2011–2014, when the difference in flare occurrence rates is properly taken into account.

Trajectoires d’activité des immigrés : une approche sociohistorique, 1968-2008
Authors: Blavier Pierre , Perdoncin Anton
Published: May 2020

Les immigrés sont souvent considérés, dans le débat public, comme s’ils formaient un ensemble homogène et indifférencié. Cet article vise à contribuer, dans la lignée d’autres travaux historiques ou sociodémographiques, à une meilleure compréhension de la diversité de leurs trajectoires en France. Pour cela, il étudie les trajectoires d’activité d’individus arrivés en France après 1968, en s’appuyant sur l’enquête Trajectoires et origines (TeO) conduite par l’Ined et l’Insee en 2008, en particulier sur son calendrier rétrospectif. La méthode d’appariement optimal, couplée à une modélisation des probabilités de transition entre divers états des trajectoires d’activité, permet de construire et de qualifier sociologiquement des types de trajectoires, mais aussi d’expliquer les transitions les plus structurantes au sein de la population entre études et non-emploi, emploi et chômage, inactivité au foyer et salariat. Les trajectoires d’activité ainsi analysées sont déterminées par le sexe, les expériences professionnelles éventuelles avant la migration, ainsi que par le pays d’origine et l’âge à la migration. Sur le plan historique, les années 1970 reconfigurent les modalités d’entrée dans un monde du travail plus précaire, plus fréquemment marqué par des moments hors salariat.
Optimization of an improved aqueous method for the production of high quality white sesame oil and de-oiled meal
Authors: Lv M. , Wu W.
Published: May 2020

Research into the production of white sesame oil by aqueous extraction has been promoted because of concerns about the environment, health, and cost. The advanced aqueous method using a 1.95:10 liquid-to-raw material ratio, which was finally developed in this study, recovered 96.06% white sesame oil and produced de-oiled meal with high quality (3.98% residual oil content). The acid value and peroxide value of the oil produced were quite low at 0.19 mg KOH/kg and < 3.25 mmol/kg, respectively, which were better than the values required by the Chinese national standard for first class edible sesame oils and oils produced by hexane extraction. No wastewater was discharged during the extraction of white sesame oils by an aqueous salt solution. The protein rich de-oiled meal may be a good material for making protein isolate with high purity (e.g. > 90%). It can also be a nutritious ingredient or raw material for producing many food products.

A Novel Greedy Forwarding Mechanism Based on Density, Speed and Direction Parameters for Vanets
Authors: Bengag Amina , Bengag Asmae , Elboukhari Mohamed
Published: May 2020

In the recent years, the study and developments of networks that do not depend on any pre-existing infrastructure have been very popular. Vehicular Ad Hoc Networks (VANETs) belong to the class of these networks, in which each vehicle participates in routing by transmitting data for other nodes (vehicles). Due to the characteristics of VANET (e.g. high dynamic topology, different communication environment, frequently link breakage…), the routing process still one of the most challenging aspects. Hence, many routing protocols have been suggested to overcome these challenges. Moreover, routing protocols based on the position of vehicles are the most popular and preferred class, thanks to its many advantages like the less control overhead and the scalability. However, this class suffer from some problems such as frequent link breakages caused by the high-mobility of vehicles, which cause a low PDR and throughput. In this investigation, we introduce a novel greedy forwarding strategy used to create a new routing protocol based on the position of vehicles, to reduce the link breakages and get a stable route that improves the PDR and throughput. The proposed Density and Velocity (Speed, Direction) Aware Greedy Perimeter Stateless Routing protocol (DVA-GPSR) is based on the suggested greedy forwarding technique that utilizes the density, the speed and the direction for selecting the most convenient relaying node candidate. The results of simulation prove that DVA-GPSR protocol outperforms the classical GPSR in all studied metrics like PDR, throughput, and the ratio of routing overhead by changing the quantity of vehicles in urban and highway scenarios.
Gender Responsive Budgeting in India
Authors: Patel Vibhuti
Published: May 2020

The budget represents the financial plan and hence is the most significant policy instrument of the government for establishing macro-economic stability, fiscal efficiency, strategic priority, and more importantly, for ensuring the equitable distribution of national resources. Gender responsive participatory budgeting (GRPB) is a means of integrating a gender dimension into all steps of the budget process that includes participatory decision making and transparency in raising financial resources and their expenditure. It is about considering the different needs and priorities of both women, men, and sexual minorities without gender exclusivity. Gender responsive budgeting (GRB) ensures that budgets are gender-sensitive and not gender neutral, which means that they are geared towards establishing gender equality and are sensitive to intersectionality of gender with class, caste, race, religion, ethnicity, and geographical location. GRB consists of the use of tools to analyze the gender dimensions of budgets; adoption of procedures to ensure that the budget supports the achievement of gender equality; and implementation mechanisms for effective and efficient utilisation of allocated funds, functions, and functionaries.

Published: May 2020

The purpose of this research is to identify the factors influencing customers' satisfaction and revisit intentions for full-service restaurants in Jakarta. The recent economic crisis is known to have had a great impact on consumer behavior with regard to restaurants. Therefore, this study is primarily focused on exploring the effects on the traditional antecedents of satisfaction and revisit intentions as full-time restaurants attempt to come up with better marketing strategies. This study involved 150 respondents who recently visited a full-service restaurant within the period of one month prior to the data collection. A confirmatory factor analysis and a reliability analysis were used to test the reliability and validity of the measurements. The hypotheses testing was conducted using a simple and multiple linear regression analysis to test the suitability of the proposed model for measuring satisfaction and revisit intentions. The results of the study showed that atmosphere has a significant influence on customer satisfaction and revisit intention. Customer satisfaction was also found as one of the most significant factors impacting revisit intention in the full-service restaurant industry. Therefore, restaurant managers can use a combination of good price and exciting atmosphere to enhance satisfaction and revisit intention. This study provides insights on full-service restaurants in Indonesia which have not received much attention in both marketing and hospitality literature.
Model Predictive Controller Design of a Wavelength-Based Thermo-Electrical Model of a Photovoltaic (PV) Module for Optimal Output Power
Authors: Gbadega Peter Anuoluwapo , Saha Akshay Kumar
Published: May 2020

As it stands, in terms of environmental impact and efficiency, photovoltaic (PV) energy has appeared to be a potential renewable power source that notably contends with the traditional power generation schemes. More so, a noteworthy factor that contrariwise influences the PV module efficiency is the PV module temperature. Therefore, the more the PV module temperature increases, the lesser the PV module efficiency. More importantly, the impact of undesired spectrum wavelengths on the PV module temperature is further reduced by passive optical filters, nonetheless, active optical filters which is more superior to the passive type, based on the PV module temperature and output power during the day, dynamically change the cut-off wavelength. Consequently, the efficiency as well as the lifecycle is both enhanced by controlling the active optical filter so as to attain optimal output power. Therefore, in this paper, a wavelength-based thermo-electrical model of a PV module was designed and simulated, the essence of this model is mainly to predict the impact of each module wavelength on both the temperature and the output power of the PV module. In view of this, since the output power is affluence by the module temperature, it is expedient to design a controller that locates the optimal cut-off spectral wavelength to lessen the module temperature whereas getting the most out of the output power over a period of time. In this vein, we designed a Model Predictive Controller whose objective is to maximize the output power by simply controlling the input power through filtering the spectrum wavelength for a photovoltaic (PV) system. The design and simulation of the plant model as well as the MPC controller were carried-out on MATLAB/Simulink environment.
Synchronized Dynamics of Hyperchaotic Flows via an Improved Finite-Time Adaptive Controller Design
Authors: Umoh Edwin A. , Iloanusi Ogechukwu N.
Published: May 2020

We proposed a performance-improved finite-time adaptive synchronizing controllers and parameter update laws for coupling the dynamics of identical 4D hyperchaotic flows. The four-dimensional hyperchaotic flows consists of 12 terms and 11 system parameters and possessed very rich dynamics and larger parameter space. The performance of the proposed finite-time adaptive synchronizing controller was enhanced by the introduction of scalar quantities known as global controller strength coefficients and parameter update strength coefficients respectively, into the algebraically-derived control and parameter update structures, in order to constrained overshoots of the trajectories of the coupled systems and accelerate their rate of uniform convergence in finite time. Numerical simulation results obtained confirmed that the uniform asymptotic convergence rate of the coupling trajectories was faster, while the parameter update laws give a stable identification of the unknown system parameters in a global synchronizing time. A comparative analysis of the convergence time of the proposed adaptive controllers with recently published works indicated that the proposed controller has faster rates of uniform convergence of system trajectories.

Published: May 2020

This study presents the analysis of thin rectangular orthotropic plate, simply supported at all edges (SSSS) subjected to both in-plane compression and lateral loads. The total potential energy functional was used in the analysis. The general variation of the total potential energy functional was done and the governing equation was obtained. The solution of the direct integration of the governing equation gave the deflection of the plate as a product of the coefficient of deflection and an orthogonal polynomial shape function. The expression for the coefficient of deflection was obtained by the direct variation of the total potential energy functional. This was used to derive the equation for the Lateral load parameter of an orthotropic thin rectangular plate carrying both in-plane compression and lateral loads based on the maximum deflection condition and also based on the elastic stability (yield strength) condition. The peculiar deflection equation for the SSSS plate was obtained using the formulated polynomial shape function. Numerical examples were carried out to determine the lateral load parameters corresponding to various plate thickness and permissible deflection for orthotropic thin SSSS plate carrying both in-plane compression and lateral load. In the same way, the lateral load parameters using the elastic stability condition (yield strength) were obtained for yield strength of 275 MPa, 355 MPa and 410 MPa

Published: May 2020

In this work, fabrication and characterization of a nanostructured rare-earth-doped ZnMoO4 will be reported. Photoluminescence properties and quantum efficiency of the rare-earth-doped ZnMoO4 with different dopant concentrations have been investigated. These samples were synthesized by sol-gel method. Lattice structure of the fabricated samples was characterized by X-ray powder diffraction (XRD); absorption spectrum was performed on UV-2600 photo spectrometer; PL excitation and emission spectra were recorded by Fluorescence Spectrometers; quantum efficiency was measured by an integrating sphere photoluminescence (PL) system. The results showed that the optimized doping concentration of Eu3+ was around 10 mol% for the highest quantum efficiency at 616 nm emission peak and 465 nm excitation peak. The highest internal quantum efficiency was 91% at low power density excitation (around 50 μW/mm2). Introduction of Mn2+ to Eu3+-doped ZnMoO4 lead to reduced quantum efficiency and electronic lifetime, which can be attributed to defects inside the crystal lattice and energy transfer from Eu3+ to Mn2+ (more non-radiative transition occur).

Published: May 2020

Physically crosslinked superabsorbent hydrogels based on NaCMC, HPC, and NaAlg were developed to address the effects of water shortage to crop farming and to regulate fertilizer usage. An optimized synthesis was performed using ten different blends. The blend with a NaCMC/HPC/NaAlg ratio of 0.29/0.42/0.29 was found to exhibit the most favorable results, accommodating 1585% moisture and 8.38% fertilizer on a dry basis. Scanning electron microscope images of this blend manifested microporous structures, responsible for its superabsorbent properties. It was found out that applying the hydrogel at 5% loading to silt soil decreases fertilizer runoff by 28% and increases field capacity to 55%. Moreover, phytotoxicity studies showed that the optimum hydrogel blend exhibits no phytotoxic properties to pechay (Brassica rapa subsp. chinensis), lettuce eton (Lactuca sativa), and spinach (Spinacia oleracea), proving its applicability to agriculture.
Intracranial Pressure Waveform Morphology and Intracranial Adaptive Capacity
Authors: Fan Jun-Yu , Kirkness Catherine , Vicini Paolo , Burr Robert , Mitchell Pamela
Published: May 2020

Background Intracranial hypertension due to primary and secondary injuries is a prime concern when providing care to patients with severe traumatic brain injury. Increases in intracranial pressure vary depending on compensatory processes within the craniospinal space, also referred to as intracranial adaptive capacity. In patients with traumatic brain injury and decreased intracranial adaptive capacity, intracranial pressure increases disproportionately in response to a variety of stimuli. However, no well-validated measures are available in clinical practice to predict the development of such an increase.

Objectives To examine whether P2 elevation, quantified by determining the P2:P1 ratio (=0.8) of the intracranial pressure pulse waveform, is a unique predictor of disproportionate increases in intracranial pressure on a beat-by-beat basis in the 30 minutes preceding the elevation in patients with severe traumatic brain injury, within 48 hours after deployment of an intracranial pressure monitor.

Methods A total of 38 patients with severe traumatic brain injury were sampled from a randomized controlled trial of cerebral perfusion pressure management in patients with traumatic brain injury or subarachnoid hemorrhage.

Results The P2 elevation was not only present before the disproportionate increase in pressure, but also appeared in the comparison data set (within-subject without such a pressure increase).

Conclusions P2 elevation is not a reliable clinical indicator to predict an impending disproportionate increase in intracranial pressure.

Published: May 2020

Due to COVID-19 outbreak, to lighten the burden of acute and critical care hospitals, some respiratory rehabilitation departments have been used to host patients with COVID-19 in the post-acute phase. This new and unexpected situation required a change of roles and scheduling of the rehabilitation teams. In this manuscript we describe the unexpected and urgent organizational change of the Cardio-Pulmonary Rehabilitation (CPR) service during the COVID-19 emergency in a Northern Italian rehabilitation hospital, focusing on the Respiratory Physiotherapists’ (RPTs) role. A quick three-days complete reorganization of the entire hospital was needed. A COVID-19 care team including a multidisciplinary panel of physicians, nurses, and RPTs was quickly performed to manage 90 beds for post acute patients with COVID-19. Within the team, the RPTs changed their shifts, so as to be available 16h per day, 7 days out of 7. Remodelled tasks in charge of RPTs were: oxygen therapy daily monitoring, non invasive ventilation (NIV) and continuous positive airways pressure (CPAP) delivery, pronation and postural changes to improve oxygenation, reconditioning with leg/arm cranking and exercises, initial and final patients’ functional assessment by short-physical performance battery (SPPB) and 1-minute sit-to-stand test (1-STS) to evaluate motor conditions and exercise-induced oxygen desaturation. Three “what-to-do” algorithms were developed to guide: i) oxygen de-escalation by reducing inhaled fraction of oxygen (FiO2); ii) oxygenation improvement through the use of Venturi mask; iii) reconditioning and physical activity. One-hundred seventy patients were treated in one month. As main topics, RPTs have been involved in oxygen therapy management in almost a third of the admitted patients, reconditioning exercises in 60% of the cases, and initial and final functional motor capacity assessment in all patients. Details of activities performed by the RPT in one typical working day are also shown. Our reorganization has exploited the professional skills and clinical expertise of the RPTs. This re-organization can provide practical insights to other facilities that are facing this crisis, and may be a starting point for implementing post-COVID-19 rehabilitation. Future studies will have to improve and review this organization.

Published: May 2020

Background: Dexmedetomidine, an alpha-2 agonist, has been used for attenuation of hemodynamic response to laryngoscopy but not through the nebulized route. We evaluated the effects of preoperative dexmedetomidine nebulization on the hemodynamic response to laryngoscopy and intubation and examined the intraoperative anesthetic-analgesic requirements and recovery outcomes. Methods: Overall, 120 ASA I & II adult patients (of either gender) undergoing elective surgeries and requiring tracheal intubation, were randomized to receive nebulized dexmedetomidine (1 µg/kg in 3–4 ml of 0.9% saline) or 0.9% saline (3–4 ml), 30 min before anesthesia induction. Heart rate and non-invasive systolic blood pressure were monitored for 10 min following laryngoscopy. Results: After laryngoscopy, linear mixed effect modelling showed significantly lower trend of increase in heart rate in the dexmedetomidine group versus saline (P = 0.012); however, there was no difference in the systolic blood pressure changes between the two groups (P= 0.904). Induction dose of propofol (P < 0.001), intraoperative fentanyl consumption (P = 0.007), and isoflurane requirements (P = 0.013) were significantly lower in the dexmedetomidine group. There was no difference in the 2-h incidence of postoperative nausea and vomiting (PONV) (P = 0.612) or sore-throat (P = 0.741).Conclusions: Nebulized dexmedetomidine at 1 µg/kg attenuated the increase in heart rate but not systolic blood pressure following laryngoscopy and reduced the intraoperative anesthetic and analgesic consumption. There was no effect on early PONV, sore-throat, or increase in incidence of adverse effects. Nebulized dexmedetomidine may represent a favorable alternative to the intravenous route in short duration surgeries.
Anesthetic management of a parturient with Shone’s syndrome -a case report with review of literature-
Authors: Bhatia Kailash , Eccles Jennifer , Meessala Dinesh. K
Published: May 2020

Background: Shone’s syndrome is a rare complex congenital cardiac condition, characterized by a supra-valvular mitral ring, parachute deformity of the mitral valve, aortic stenosis, and coarctation of the aorta.Case: A 26-year-old parturient with partial Shone’s syndrome presented to our delivery unit in pulmonary edema. She underwent a scheduled cesarean section performed under a combined spinal-epidural anesthetic at 33 weeks. She had multidisciplinary input from the cardiac, obstetric, and anesthetic teams, which led to a good outcome. A review of the five published case reports of Shone’s syndrome in pregnancy is presented along with key findings.Conclusions: Our case report and the review highlight the successful use of combined spinal-epidural anesthetic and provides guidance to the multidisciplinary team on the varied presentation and the optimum management of women with Shone’s syndrome during the peripartum period.
On the viscous Burgers equation on metric graphs and fractals
Authors: Hinz Michael , Meinert Melissa
Published: May 2020

We study a formulation of Burgers equation on spaces carrying a local regular resistance form in the sense of Kigami. One possibility is to implement Burgers equation as a semilinear heat equation associated with the Laplacian for scalar functions, just as on the unit interval. Here we propose a second, different formulation which follows from the Cole–Hopf transform and is associated with the Laplacian for vector fields. On metric graphs the difference between these two equations can be understood in terms of different vertex conditions. For the second formulation we show existence and uniqueness of solutions and verify the continuous dependence on the initial condition. For resistance forms associated with regular harmonic structures on p.c.f. self-similar sets we also prove that solutions can be approximated in a weak sense by solutions to corresponding equations on approximating metric graphs. These results are part of a larger program discussing non-linear partial differential equations on fractal spaces.
Apontamentos sobre as frentes pioneiras na Zona da Mata Rondoniense (1970-2000)
Authors: Trubiliano Carlos Alexandre Barros
Published: May 2020

Desde o período imperial, existe uma preocupação, por parte do Estado nacional, com a defesa da fronteira oeste brasileira, especialmente após a guerra contra o Paraguai (1864-1870), momento em que se tornam públicas as fragilidades desse território. Diante das vulnerabilidades, já no período republicano, algumas ações – como a expansão de unidades militares, a construção das linhas telegráficas e das ferrovias Madeira-Mamoré e Noroeste do Brasil e, posteriormente, a construção da BR 364 – objetivavam a demarcação e efetiva integração dessa região ao território nacional. Um dos efeitos da construção dessas vias de comunicação, ao longodo século XX, foi o surgimento de redes de cidades, entre elas a rede urbana da Zona da Mata Rondoniense. Esse ensaio aponta alguns indicativos de desenvolvimento socioeconômico que ajudam a compreender as frentes pioneiras e o processo de formação urbana da rede de cidades da Zona da Mata Rondoniense entre os anos de 1970 a 2000.

Published: May 2020

El bajo rendimiento estudiantil en asignaturas que requieren habilidades matemáticas, lógicas y computacionales para la resolución de problemas, especialmente en asignaturas de computación, demanda cambios en su enseñanza. Una propuesta es la aplicación del Aprendizaje Basado en Problemas (ABP), el cual contribuye con el aprendizaje por descubrimiento y construcción. El objetivo es diseñar una estrategia de enseñanza para resolver problemas de origen computacional en la fase de Análisis Orientado a Objetos (AOO) usando ABP. El estudio  es de tipo proyecto, apoyada en un estudio de campo de descriptivo. La población de estudio estuvo conformada por 232 estudiantes y por 12 profesores de una universidad venezolana. Como resultado se diseña una Estrategia de Enseñanza de Computación en Ingeniería (ESENCI) que comprende las fases de planificación y ejecución, las cuales comprenden actividades que el profesor ejecuta para construir el problema y diseñar mejores condiciones para su resolución por parte del estudiante. ESENCI contempla el fortalecimiento de competencias instrumentales, interpersonales y sistémicas.

El siguiente artículo se genera a partir de una investigación  cuyo  propósito fue proponer una Valija Didáctica como recurso para el estudio geográfico y conservación de la Reserva de Fauna Silvestre “Esteros de Camaguán”. Dirigida a docentes del Área Ciencias Sociales  del Liceo “Germán Fleitas Beroes” ubicado en Camaguán, estado Guárico. Con esta propuesta se pretende dar respuesta a la falta de recursos didácticos, específicamente en el desarrollo de contenidos programáticos de Geografía de Venezuela. El trabajo se abordó como proyecto especial, con un estudio explicativo, apoyado en investigación documental y de campo. Se encontró ausencia de recursos didácticos durante el desarrollo de clases, entre ellos mapas, esferas, software, equipos GPS y otros. Se concluye que con la utilización de la Valija es posible orientar la enseñanza geográfica desde lo local y lo endógeno. Finalmente, se espera que ésta contribuya a propiciar un mejor conocimiento geográfico de los ecosistemas del lugar estudiado
