Authors: Santos Carlos Alberto dos , Lima Francisco Cristiano Barbosa , Barbosa Geovani Ferreira , Silveira Fernando Lang da
Published: August 2019

Experimentos com materiais de baixo custo, inteiramente confeccionados por alunos do 3o. Ano do Ensino Médio de uma escola pública no Estado do Ceará, foram utilizados para abordar concepções alternativas sobre circuitos elétricos simples. Entrevistas clínicas realizadas com 13 alunos selecionados de acordo com o padrão de suas respostas no teste de múltipla-escolha elaborado para investigar concepções alternativas e de seus rendimentos escolares na disciplina antes do experimento, mostraram a recorrência de concepções alternativas, bem como a falta de consistência nas respostas escritas, em conformidade com relatos na literatura. As entrevistas clínicas, realizadas aproximadamente um mês após a manipulação dos experimentos, mostraram que a simples realização dos experimentos não é capaz de superar as concepções alternativas mais persistentes. Não obstante, acredita-se que o uso concomitante de experimentos e entrevistas clínicas, pode ser potencialmente útil para proporcionar mudanças conceituais. Na prática escolar, tal procedimento pode subsidiar o estabelecimento de estratégias didáticas para a superação das mais recorrentes concepções alternativas.

Published: August 2019

O smartphone é um dispositivo tecnológico capaz de realizar diferentes tarefas que vão desde a simples comunicação entre duas pessoas até a localização através do GPS, recursos biométricos de identificação de retina e digitais, registro de frequência cardíaca, dentre outros. O desenvolvimento e a constante evolução das tecnologias presentes nos smartphones proporcionaram o barateamento e a diminuição dos sensores nele presentes, permitindo assim, a popularização dessas ferramentas de medição. Esses sensores, com o auxílio de aplicativos adequados, podem ser utilizados para fins didáticos visto que, possibilitam a aquisição automática de dados de diferentes grandezas físicas. No presente trabalho apresentamos uma proposta de atividade experimental com materiais de baixo custo e uso cotidiano, como uma mola, uma régua e um smartphone, para o estudo de oscilações amortecidas em regime subcrítico. O objetivo é mostrar que apesar da simplicidade dos materiais é possível se obter resultados satisfatórios acerca de um experimento didático, mesmo na ausência de sofisticados equipamentos de laboratório. Com as medidas de aceleração em função do tempo nos três eixos espaciais obtidas pelo aplicativo Sensor Kinetics foi possível calcular os valores da constante de amortecimento e da constante elástica da mola, além da construção dos gráficos das assíntotas superiores e inferiores da posição, velocidade e aceleração que modelam o movimento oscilatório.

Published: August 2019

ABO blood grouping is an important antigenic blood typing tools in blood transfusion and organ transplants. Mismatching of blood during transfusion would lead to undesired transfusion reactions. Due to rare occurrence of rare blood group such as A2 subtype, regular blood grouping technique would have missed the identification of blood group. In this study, the identification of A2 subgroup using routine serological technique was validated via DNA sequencing technique. A total of 656 students participated in this study consist of Malay (87.0 %), Chinese (0.4 %), Indian (11.4 %) and others ethnic group (0.9%) respectively. Monoclonal antisera A, B, AB, D, A1 lectin and H lectin were used to identify the antigen on red blood cells. DNA sequence analysis was applied to examine single nucleotide polymorphisms (SNPs) at position 467 (substitution of C>T) and 1061 (deletion of C) on coding region of ABO gene. Our findings showed of 656 blood samples, 256 (39.0%) were blood group O, 190 (29.0%) were blood group B, 179 (27.3%) were blood group A and 31(4.7%) were blood group AB. The frequency of A1 subgroup is 177 (99.0%) and A2 subgroup is 2 (1.0%). From 179 A blood group, only 2 samples showed negative reaction towards anti-A1 lectin. DNA sequence analysis revealed the SNPs at nucleotide 1061 position in sample 2, however sample 1 did not have this mutation and the subgroup was not identified. DNA sequencing provides a precise and high accuracy in identification of A subgroups.

Recognition of health benefits associated with consumption of marine derived biomasses is one of the most promising developments in human nutrition and disease-prevention research. This endeavor for bioactives and functional ingredients discovery from marine sources is “experience driven,” as such the search for therapeutically useful synthetic drugs, and functional components is like “looking for a needle in a haystack,” thus a daunting task. Zoonotic infection, adulteration, global warming and religious belief can be the star-gate barrier: - For example, the outsourcing for Glycosaminoglycans (GAGs), a pharmacologically bioactive compound have emerged as novel biomarkers and molecular players both within tumor cells and their microenvironment, as they integrate signals from growth factors, chemokines, integrins, and cell-cell matrix adhesion. As such, worldwide initiatives in outsourcing from geochemical signatures marine biomasses are flourishing. Most of these scientific interests are related to marketable compounds optimised via biotechnology applications. Approximately 50% of the US FDA approved drugs during 1981–2002 consist of either marine metabolites or their synthetic analogs. These bioactive compounds acts as antioxidant, peptides, chitoligosaccharides derivatives, sulfated polysaccharides, phlorotannins and carotenoids. Highlights from works to harness and provide scientific support to folk medicine much claimed legacy, pertaining to geochemical signatures vouchered sea cucumbers, macroalgae and crown of thorns starfish will be extrapolated.

Published: August 2019

The predecessors of rice, combined with their characteristic agricultural machinery, restore soil fertility, increase the yield of rice, provide forage products and as a result determine the productivity of the entire rotation of the crop rotation. In the rice crop rotations of the Sarpinsky lowland, studies are conducted to study the yield of alfalfa of the 1st year of life in the rice crop rotation on the reserves of productive moisture remaining after rice at different seeding rates. The soil cover of rice cheques is represented by brown semi-desert medium-and heavy-loamy soils in combination with saline. In the first year of the life of alfalfa (Medicago sativa L.) two residues of above-ground mass were obtained on residual moisture reserves (250–320 mm) after rice. The maximum yield of hay for two mowing 2.86-3.62 t/ha was obtained in the version with a seeding rate of 9.0 million pieces /ha, which is 0.86-1.21 t/ha more than the control option (5.0 million pcs/ha). It has been developed a dynamic model based on the yield of hay from alfalfa seeding rate seed having parabolic form with a maximum on top with a seeding rate of 9.0 million pcs/ha.

The studies used the methods of the State Commission for varietal testing and statistical processing of the results according to the method of Dospekhov. Field germination in all varieties turned out to be higher when sown with 15 cm row spacing, and the safety of plants for harvesting when sowing with 30 cm row spacing. The vegetation period averaged 102-112 days. In all varieties, the ordinary method allowed to start cleaning 3-4 days earlier. In all varieties, the ordinary method allowed to start cleaning 3-4 days earlier. In the wet year of 2017, bean plants with all sowing methods were higher, but less productive beans were formed on the plants. Sowing methods have had an ambiguous impact on the elements of the crop structure. Thus, in the Ballada and Mistress’s dream varieties, the size of the seeds increases with wide-row sowing, and in the Chocoladnitsa and Mistress’s Dream varieties the number of beans per plant. In 2017, the mistress’s dream variety turned out to be the most productive, while the wide-row sowing reliably exceeded the average by 0.45 t / ha. In 2018, the sowing variant of the ordinary (15 cm) method proved more effective in all varieties. The maximum yield was recorded for the Variety Chocolate variety in 2018 when sowing with 15 cm row spacing - 6.87 t / ha. The results indicate that in the conditions of the Chuvash Republic beans are able to mature and form consistently high yields.

Published: August 2019

Destructive nature along with the associated higher cost of the traditional core method used for hot mix asphalt density measurement has convinced researchers switching to some non-destructive technique for this purpose which is cost efficient as well. Earlier, nuclear density gauges were introduced for this purpose which was non-destructive as well. Since such devices were associated with the use of gamma rays, therefore, leading to safety and health issues. Last decade observed a revolution in asphalt density measurement technique with the evolution of non-nuclear density gauges. This research work is carried out with the objective to determine the efficiency and accuracy of a newly developed non-nuclear density gauge i.e. PQI-380 for field conditions as it needs its thorough evaluation prior to future uses in many of the developing countries including Pakistan. Density data obtained using standard core method and non-nuclear density gauge for 195 location confirms the satisfactory performance of the instrument. Results obtained show that the coefficient of correlation is near to 0.9. which refers to a strong correlation between the density data. Moreover, performance criteria e.g. root mean square error and mean absolute error between the density data set is also very low confirming the good measuring abilities of the device. Instrument performed well for repeatability analysis giving maximum coefficient of variance less than 5 percent.

Published: August 2019

The assessment of the residual strength of post-heated concrete structural members in a professional way is a prime factor to take a decision about the restoration or destruction of fire-damaged structure. This Paper explores the numerical modelling of RC square columns damaged by exposure to heat at 5000C, unjacketed. Software ABAQUS was used for numerical modelling of fire damaged compression member i-e column. The main objective of this study is prediction of axial load and axial deformation of fire damaged concrete using finite element studies. Moreover, a parametric nonlinear finite element (FE) research is carried out to check the effect of viscosity parameters on numerical simulation of fire damaged concrete columns. For the said objectives, numerical simulation of existing experimental study of fire damaged RC columns is conducted with varied values of viscosity parameters. The numerical analysis (Finite Element Modeling) indicated that axial load capacity decreases and axial deformation increases after exposure to fire. The experimental and numerical studies are compared in terms of load displacement analysis. The use of optimum viscosity parameter and its definition to FEM improves significantly the performance of convergence and reduces analysis time of numerical simulations of RC square columns.  Moreover, a good agreement was found between the experimental and the finite model results.

Published: August 2019

Corrosion of steel in concrete elements is a major issue in concrete structures. In order to overcome this matter, Glass Fiber Reinforced Polymer (GFRP) reinforcement is being used in concrete members from almost 20 years ago. Although it has been used and developed in recent years, there are still some uncertainties for the application of FRP reinforcement, especially in concrete columns.  Most codes such as ACI, CSA, JSCE & etc. neglects the effect of these reinforcements or they do not permit them in compressive concrete elements. In this essay, it has been shown that these rebar can contribute significantly in compressive strength of concrete columns if the column confinement is provided sufficiently. In order to achieve the required confinement to reach a sharp contribution of GFRP longitudinal rebar in concrete columns, the spiral of FRP rebar with small pitches around longitudinal rebar is taken into account. This leads to higher strains of concrete which can result in a higher contribution of FRP longitudinal rebar. Foremost, equations related to the compressive strength of concrete columns considering the influence of spiral confinement will be carried out. Then, a parametric study will be performed, and the effects of pitch, concrete strength, column diameter, the quantity of longitudinal rebar and concrete cover will be investigated.
Modeling high-resolution down-hole pressure transducer to achieve semi-distributed measurement in oil an d gas production wells
Authors: Silva Leonardo BM , Santos Edval JP
Published: August 2019

A full 3D computer model is developed to evaluate the performance impact of intrinsic loss and various geometrical features in high-resolution pressure transducer. The intrinsic loss is modeled as viscosity factors, which allows for a more efficient computer model. In this paper, the developed model is applied to yield an insight in the evolution of high-resolution down-hole pressure transducer, from Hewlett-Packard\texttrademark\, to Quartzdyne\texttrademark. As the quality factor is related to the inverse of the resolution, the transducing element optimization process to achieve the highest quality factor possible is investigated, considering the impact of crystal quality and geometrical features, such as: thickness, diameter and convexity (plano-convex and bi-convex). Temperature-dependent elastic constants are used to improve the model accuracy in modeling temperature effects on the vibrating resonator-type transducer. Boundary load conditions are used to simulate hydrostatic pressure. The simulations to extract the frequency shift are carried out in the range of $14\,psi$ ($96.5\,kPa$) to $20000\,psi$ ($137.89\,MPa$) and $0\,^oC$ to $200\,^oC$ for pressure and temperature, respectively, as such ranges are typically found in oil and gas wells. A discrepancy in the published temperature dependence has been found. A miniaturization path to achieve semi-distributed measurement in oil and gas production wells is presented.

Published: August 2019

A flower-shape bio-inspired aperture-coupled antenna array for on-chip application, generated by Gielis formula, operating in industrial, scientific and medical (ISM) band at 60 GHz (57 GHZ to 64 GHz) is presented in this paper. The antenna proposed is composed of a transmission feed line followed by an aperture and patch element built in aluminum, with 2 micrometers of thickness, lying on two layers of silicon with 200 micrometers of thickness each. Dimensions of the antennas were calculated according to the effective wavelength for the resonance frequency at 60 GHz. Simulations were performed in the commercial software ANSYS® Electronics Desktop. The use of the bio-inspired flower-shape promotes more compact structures with greater perimeter, rearranging these shapes into an antenna array provided a gain and a bandwidth increase in the design, 3.11dBi and 2.86GHz, respectively, which resulted in a maximum gain of 8.82 dBi and a total bandwidth of 5.88 GHz.

Authors: Nunes Rafael Oliveira , De Orio Roberto Lacerda
Published: August 2019

A method to calculate the temperature distribution on the BEOL structure and its impact on the EM in a design environment has been developed and implemented. The study for a 45 nm technology indicated a large temperature variation from the local to the global interconnects, which should be considered for the EM induced resistance increase of the line, in contrast to the standard analysis through a fixed operation temperature throughout the BEOL. The results show that a significant additional temperature above 50°C exist on the layers M1 to M6 due the power dissipated from transistors. The temperature reduction on the local layer is evaluated increasing the number of vias and enlarging the interconnect lines, both with a direct influence on the BEOL thermal distribution. A reduction of 62.9°C is obtained for M1 layer, considering a fraction volume of 40% for lines and 6% for vias.
PWM output CMOS Stress Sensor based in PiezoFET current mirrors
Authors: Ramirez Bohorquez Jose Luis , Fruett Fabiano
Published: August 2019

This work shows the design and characterization of a stress sensor based on piezoFET current mirrors with a Pulse Width Modulated output, a compact device designed to be integrated in any CMOS process which is suitable to estimate the stress state over the silicon surface. The multi-terminal device integrates the piezo-MOSFETs with different alignments within current mirrors with the bias circuits to extract differential currents, which are related to the different stress components at the surface of the device. The analog current outputs are converter into single-bit digital signal using a Pulse Width modulator. In the absence of stress, the duty cycle of the output is 50%, but if stress is applied, the mismatches in the currents generate a shift in the duty cycle proportional to the stress. Since there are piezoFET aligned in different directions, it is possible to add the currents to isolate effect of the different stress components.  The piezoFET current mirrors and the PWM stress sensor were characterized using a four-point bending test; a controlled uniaxial stress in a range [5MPa, 70MPa] was applied aligned to the main crystallographic directions of the device surface, while both the currents at the piezoFET mirrors and the digital output are observed. The analog outputs show a linear behaviour with stress and fit the equations from the piezoresistive effect while the duty cycle of the digital output varies also linearly around the 50%.
