Authors: Bypour Maryam , Kioumarsi Benyamin , Kioumarsi Mahdi
Published: May 2019

In this paper, the behavior of steel plate shear wall (SPSW) in the reinforced concrete frame (RCF) has been studied numerically. Three different connections have been proposed to connect SPSW to RCF. In the first connection, fish plates, while in the second one, combination of fish plates and studs transfer forces between SPSW and RCF. In the third connection, there is no direct connection between the infill plate and RCF, and additional steel frame has been used for connecting of the infill plate. The results demonstrate that, load carrying capacity increases in all the specimens comparing the reference RCF. Investigating the formation sequence of plastic hinges in different specimens demonstrates that there is different sequence in the specimens with different connections.

Authors: Wang Wen Hao , Liu Xin Yu , Pan Lu
Published: May 2019

In the experiments of different process parameters (laser power, scanning speed and scanning distance),the low-time defects of forming part were studied by microscope,including air bubble, pore, micro-crack and macro-crack. The formation mechanism of bubble-defect was analyzed.Linear energy density (E=P/v) was introduced as synthetic parameter.According to analysis and test verification, the optimum technological parameters of 316L stainless steel were laser power 190-210KW, laser speed 800-1000mm/s and scanning interval 0.9-0.11mm,and the linear energy density was about 200J/m. There were no cracks, no bubbles, a small amount of porosity, and the product density reached 99.7%.
Impact Response of Reinforced Concrete Columns with Different Axial Load under Low-Velocity Impact Loading
Authors: Tantrapongsaton Warakorn , Hansapinyo Chayanon
Published: May 2019

Building collapses from the seismic pounding of two adjacent buildings have been found in many past earthquakes. For the two buildings with different story height, the pounding induces impact load and local stress at column mid-height where the provided column reinforcement is normally lesser than the column’s edge. This paper aims to investigate the impact responses of reinforced concrete columns with different axial load and shear capacity by using numerical simulation method. Sixteen reinforced concretes columns were subjected to an impact load created by dropping 300 kg hammer at the height of 1,200 mm above the mid-span of the column. Every specimen has an identical cross section of 220 mm by 220 mm, with 3,000 mm of clear span length. Both ends of the column were fully restrained. The magnitude of the axial load varies from 0% to 40% of the ultimate axial capacity of the concrete section. Shear reinforcement spacing varies from @200 mm to @60 mm. It is found that the axial loads have a great effect on the impact responses of the RC columns. The specimens with high axial load yield higher peak impact force value and less mid-span deflection. Shear cracks were observed on the specimens with low axial force, but the cracks were relatively decreased when increasing the axial load.
Influence of Sargassum crassifolium Extract on the Absorption of Magnetic Iron Oxide Nanoparticle via Green Synthesis Route
Authors: Budlayan Marco Laurence M. , Alguno Arnold C. , Capangpangan Rey Y.
Published: May 2019

This work reported the influence of seaweed (Sargassumcrassifolium) extract on the absorption of magnetic iron oxide nanoparticles (MIONPs) via green synthesis route. The seaweed extract acted as reducing and capping agent. Ultraviolet-visible (UV-Vis) spectra revealed the presence of sharp peaks at around 366 nm to 371 nm which corresponds to the absorption spectra of MIONPs. The absorption peaks corresponding to MIONPs was significantly affected by the varying amount of seaweed extract. On the other hand, Fourier Transform-Infrared (FTIR) spectra revealed the presence of the vibration mode around 532 cm-1 to 551 cm-1 which corresponds to Fe-O bands suggesting the successful formation of MIONPs. Thermogravimetric (TGA) spectra showed that the produced MIONPs stabilizes at 400 °C. The synthesized MIONPs are spherical in shape with an estimated average diameter of 20 nm as revealed by the Field Emission Scanning Electron Microscopy (FESEM). Finally, the produced MIONPs exhibit magnetic property via attraction with an external magnet. This straight forward green synthesis of MIONPs can be a good route for possible industrial and environmental application.

Published: May 2019

The corrosion behavior of galvanized steel in corrosive media of simulated concrete pore solution (SPS) with and without NaCl has been studied for applying it to porcelain insulator’s pins in high-voltage alternating current (HVAC) transmission line. It was found that zinc coating of galvanized steel was corroded increasingly for the first 3 days corrosion test in SPS mixed with NaCl solution. After that the passive layer was formed on the surface of galvanized coating and consequently, the corrosion rate was dramatically decreased nearly five times of initial corrosion rate after 21 days. In this experiment, the investigations have been performed by SEM, optical microscope and visual observation. The results show that this compact and well adherence passive layer can be effectively hindered the corrosion process.
A Study on the Prediction of Strength of Trimodal Composites
Authors: Suh Yeong Sung
Published: May 2019

Particle-reinforced trimodal composites, which typically consist of three constituent phases where at least one phase forms itself a composite with ceramic particles, feature a length-scale-dependent strengthening. Joshi and Ramesh [1] presented a secant Mori–Tanaka method to describe the strength of trimodal composites. They, however, seem to have used excessively high strength by mismatch in coefficients of thermal expansion between ultrafine-grained 5083 aluminum and B4C particles. Since the ultrafine-grained 5083 aluminum features high strength, an additional enhancement of strength by this kind of thermoelastic mismatch between matrix and particle may hardly occur. Using finite-element methods with strain-gradient plasticity, this problem is examined computationally and an enhanced procedure of strength prediction for trimodal composites is suggested.
Comparative Investigation into the Electromagnetic Wave Shielding Effectiveness of Different Type Carbon-Based Fabrics
Authors: Kim Hyun Ji , Kim Sung Hoon
Published: May 2019

Different type carbon-based fabrics, namely woven or nonwoven fabric, were employed to investigate the electromagnetic wave shielding effectiveness of the fabrics in the wide operating frequency range, namely 0.4GHz to 40GHz. The surface and cross sectional morphologies of the fabrics, their electrical conductivities, and their electromagnetic wave shielding effectiveness were investigated. In the case of woven fabric, the value of the electrical conductivity was much different according to the measuring direction in the woven fabric. For the nonwoven fabric, however, this value was independent on the measuring direction. The shielding effectiveness of the woven fabric was above 20dB in the range of 0.04GHz to 4GHz and then it decreased to below 20dB in the range of 4GHz to 40GHz. In contrast, the shielding effectiveness of nonwoven fabric was above 40dB in the whole operating frequency range in this work. Based on these results, the dependence of the shielding effectiveness of the woven or nonwoven fabrics according to the operating frequency and the optimal shielding effectiveness material in the wide operating frequency range was suggested and discussed.

Anterior mediastinal masses are relatively uncommon and include a wide variety of lesions. Lymphomas account for 25% of anterior mediastinal masses. Lymphomas and other haematological malignancies are associated with pericardial effusion. There are also cases where a cardiac tamponade occurred. The aim of the case reported herein is to discuss the surgical approach and particularly the mediastinal debulking as an adjunct to systematic treatment for haematological diseases presenting as an anterior mediastinal mass responsible for a cardiac tamponade.
Parabolic dynamics and anisotropic Banach spaces
Authors: Giulietti Paolo , Liverani Carlangelo
Published: May 2019

We investigate the relation between the distributions appearing in the study of ergodic averages of parabolic flows (e.g. in the work of Flaminio–Forni) and the ones appearing in the study of the statistical properties of hyperbolic dynamical systems (i.e. the eigendistributions of the transfer operator). In order to avoid, as much as possible, technical issues that would cloud the basic idea, we limit ourselves to a simple flow on the torus. Our main result is that, roughly, the growth of ergodic averages (and the characterization of coboundary regularity) of a parabolic flow is controlled by the eigenvalues of a suitable transfer operator associated to the renormalizing dynamics. The conceptual connection that we illustrate is expected to hold in considerable generality.
Neurocommunicative methodologies: attention and emotion of the audiovisual story in the classroom
Authors: Izquierdo Vanessa , Garrigues María Luisa
Published: May 2019

Audiovisual content as a learning tool has been incorporated extensively into lecture classes. Emotion-cognition is intrinsic to the functioning of the human brain, and therefore can explain the acquisition of knowledge and competencies in the educational field, and more specifically, the transformative impact on digital natives. Advances in the study of the brain have allowed for quantitative measurement of attentional (EDL) and emotional (EDR) terms. The objective of this article is to analyze and evaluate the correlation between attention and emotion during the viewing of two videos shown in a classroom in the academic space of a university. The method consisted of recording the electrodermal activity of various groups of Audiovisual Communication and Advertising and Public Relations students during the viewing of the two audiovisual stories. The main results and conclusions link characteristics of the audiovisual narrative and technical-expressive qualities and objectives of the videos with the levels of EDL and EDR recorded by the device and establish advanced lines of research in the field of neuroeducation and neurocommunication.

The application and effectiveness of coaching and gamification techniques and the innovative pedagogical strategies integrated in the so-called flipped classroom are analyzed. The results obtained with the application of these methodologies allow us to conclude that the analyzed pedagogical tools are ideal to increase the learning capacities and personal development of the students.
A new roughness length parameterization accounting for wind–wave (mis)alignment
Authors: Porchetta Sara , Temel Orkun , Muñoz-Esparza Domingo , Reuder Joachim , Monbaliu Jaak , van Beeck Jeroen , van Lipzig Nicole
Published: May 2019

Abstract. Two-way feedback occurs between offshore wind and waves.
However, the influence of the waves on the wind profile remains understudied,
in particular the momentum transfer between the sea surface and the
atmosphere. Previous studies showed that for swell waves it is possible to
have increasing wind speeds in case of aligned wind–wave directions. However,
the opposite is valid for opposed wind–wave directions, where a decrease in
wind velocity is observed. Up to now, this behavior has not been included in
most numerical models due to the lack of an appropriate parameterization of
the resulting effective roughness length. Using an extensive data set of
offshore measurements in the North Sea and the Atlantic Ocean, we show that
the wave roughness length affecting the wind is indeed dependent on the
alignment between the wind and wave directions. Moreover, we propose a new
roughness length parameterization, taking into account the dependence on
alignment, consisting of an enhanced roughness length for increasing
misalignment. Using this new roughness length parameterization in numerical
models might facilitate a better representation of offshore wind, which is
relevant to many applications including offshore wind energy and climate
modeling.
CAFE: a new, improved non-resonant laser-induced fluorescence
instrument for airborne in situ measurement of formaldehyde
Authors: St. Clair Jason M. , Swanson Andrew K. , Bailey Steven A. , Hanisco Thomas F.
Published: May 2019

Abstract. NASA Compact Airborne Formadehyde Experiment (CAFE) is a non-resonant laser-induced fluorescence instrument for airborne in situ measurement of formaldehyde (HCHO). The instrument is described here with highlighted improvements from the predecessor instrument, COmpact Formaldehyde FluorescencE Experiment (COFFEE). CAFE uses a 480 mW, 80 kHz laser at 355 nm to excite HCHO and detects the resulting fluorescence in the 420–480 nm range. The fluorescence is acquired at 5 ns resolution for 500 ns and the unique time profile of the HCHO fluorescence provides measurement selectivity. CAFE achieves a 1-sigma precision of 160 pptv (1 s) and 90 pptv (10 s) for [HCHO] = 0 pptv. CAFE has successfully flown on multiple aircraft platforms and is particularly well-suited to high altitude research aircraft or small air quality research aircraft where high sensitivity is required but operator interaction and instrument payload is limited.
Coupled calcium and inorganic carbon uptake suggested by magnesium and sulfur incorporation in foraminiferal calcite
Authors: van Dijk Inge , Barras Christine , de Nooijer Lennart Jan , Mouret Aurélia , Geerken Esmee , Oron Shai , Reichart Gert-Jan
Published: May 2019

Abstract. Shell chemistry of foraminiferal carbonate proves to be
useful in reconstructing past ocean conditions. A new addition to the proxy
toolbox is the ratio of sulfur (S) to calcium (Ca) in foraminiferal shells,
reflecting the ratio of SO42- to CO32- in seawater. When
comparing species, the amount of SO42- incorporated, and therefore
the S∕Ca of the shell, increases with increasing magnesium (Mg) content. The
uptake of SO42- in foraminiferal calcite is likely connected to
carbon uptake, while the incorporation of Mg is more likely related to Ca
uptake since this element substitutes for Ca in the crystal lattice. The
relation between S and Mg incorporation in foraminiferal calcite therefore
offers the opportunity to investigate the timing of processes involved in Ca
and carbon uptake. To understand how foraminiferal S∕Ca is related to Mg∕Ca,
we analyzed the concentration and within-shell distribution of S∕Ca of three
benthic species with different shell chemistry: Ammonia tepida, Bulimina marginata and Amphistegina lessonii. Furthermore, we
investigated the link between Mg∕Ca and S∕Ca across species and the
potential influence of temperature on foraminiferal S∕Ca. We observed that
S∕Ca is positively correlated with Mg∕Ca on a microscale within specimens, as
well as between and within species. In contrast, when shell Mg∕Ca increases
with temperature, foraminiferal S∕Ca values remain similar. We evaluate our
findings in the light of previously proposed biomineralization models and
abiological processes involved during calcite precipitation. Although all
kinds of processes, including crystal lattice distortion and element
speciation at the site of calcification, may contribute to changes in either
the amount of S or Mg that is ultimately incorporated in foraminiferal
calcite, these processes do not explain the covariation between Mg∕Ca and
S∕Ca values within specimens and between species. We observe that groups of
foraminifera with different calcification pathways, e.g., hyaline versus
porcelaneous species, show characteristic values for S∕Ca and Mg∕Ca, which
might be linked to a different calcium and carbon uptake mechanism in
porcelaneous and hyaline foraminifera. Whereas Mg incorporation might be
controlled by Ca dilution at the site of calcification due to Ca pumping, S
is linked to carbonate ion concentration via proton pumping. The fact that
we observe a covariation of S and Mg within specimens and between species
suggests that proton pumping and Ca pumping are intrinsically coupled across
multiple scales.

Published: May 2019

Abstract. Deciphering the dynamics of dissolved oxygen in the mid-depth ocean during the last deglaciation is essential to understand the influence of climate change on modern oxygen minimum zones (OMZs). Many paleo-proxy records from the Eastern Pacific Ocean indicate an extension of oxygen depleted conditions during the deglaciation but the degree of deoxygenation has not been quantified to date. The Peruvian OMZ, one of the largest OMZs in the world, is a key area to monitor such changes in near-bottom water oxygenation in relation to changing climatic conditions. Here, we analysed the potential to use the composition of foraminiferal assemblages from the Peruvian OMZ as a quantitative redox-proxy. A multiple regression analysis was applied to a joint dataset of living (rose Bengal stained, fossilizable calcareous species) benthic foraminiferal distributions from the Peruvian continental margin. Bottom-water oxygen concentrations ([O2]BW) during sampling were used as dependant variable. The correlation was significant (R2 = 0.82; p
Using Remote Sensing to Monitor the Spring Phenology of Acadia National Park across Elevational Gradients

Published: May 2019

Abstract. Greenup dates of the mountainous Acadia National Park, were monitored using remote sensing data (including Landsat 8 surface reflectances (at a 30 m spatial resolution) and VIIRS reflectances adjusted to a nadir view (gridded at a 500 m spatial resolution)) during the 2013–2016 growing seasons. Ground-level leaf-out monitoring in the areas alongside the north-south-oriented hiking trails on three of the park's tallest mountains (466 m, 418 m, and 380 m) was used to evaluate satellite derived greenup dates in this study. While the 30 m resolution would be expected to provide a better scale for phenology detection in this mountainous region than the 500 m resolution, the daily temporal resolution of the 500 m data would be expected to offer vastly superior monitoring of the rapid variations experienced during vegetation greenup along elevational gradients. Therefore, the greenup dates derived from the Landsat 8 Enhanced Vegetation Index (EVI) data, augmented with Spatial and Temporal Adaptive Reflectance Fusion Model (STARFM) simulated EVI values, does provide more spatial details than VIIRS data alone and agree well with field monitored leaf out dates. Satellite derived greenup dates from the 30 m of Acadia National Park vary among different elevational zones, although the date of greenup is not always the most advanced at the lowest elevation. This indicates that the spring phenology is not only determined by microclimates associated with different elevations in this mountainous area, but is also possibly affected by the species mixture, localized temperatures, and other factors in Acadia.
Global scale human pressure evolution imprints on sustainability of
river systems
Authors: Ceola Serena , Laio Francesco , Montanari Alberto
Published: May 2019

Abstract. Human pressures on river systems pose a major threat to the sustainable development of human societies in the twenty first century, with severe implications for anthropogenic activities and river ecosystems. Previous studies showed that a large part of the global population was exposed to relevant threats to water security already at the beginning of this century. A relevant question, which was never explored by the literature so far, is whether these threats are increasing in time, therefore representing a potential future challenge to the sustainability of river systems. This paper proposes a simple, objective and effective index we call Differential Human Pressure on Rivers (DHPR) to measure the annual evolution of human pressure on river systems. DHPR identifies a per year percentage increment (or decrement) of normalized human pressures (i.e., ratio of annual values to long term average). This index, based on annual nightlights and time invariant discharge data, is estimated for 2195 major river basins over a period of 22 years, from 1992 to 2013. The results show that normalized annual human pressure on river systems increased globally by a DHPR value equal on average to 1.9 % and that the greatest increase occurred within the northern tropical and equatorial areas. The evaluation of DHPR over this 22 year period allows the identification of hot spot areas, therefore offering guidance on where the development and implementation of mitigation strategies and plans are most needed (i.e., where human pressure is strongly increasing).
Implications of different nitrogen input sources for potential production and carbon flux estimates in the coastal Gulf of Mexico (GOM) and Korean coastal waters
Authors: Kim Jongsun , Chapman Piers , Rowe Gilbert , DiMarco Steven F.
Published: May 2019

Abstract. The coastal Gulf of Mexico (GOM) and Coastal Sea off Korea (CSK) both suffer from human-induced eutrophication. We used a N-mass balance model in two different regions with different nitrogen input sources to estimate organic carbon fluxes and predict future carbon fluxes under different model scenarios. The coastal GOM receives nitrogen predominantly from the Mississippi and Atchafalaya Rivers and atmospheric nitrogen deposition (AN-D) is only a minor component in this region. However, in the CSK, groundwater and atmospheric nitrogen deposition are more important controlling factors. Our model includes the fluxes of nitrogen to the ocean from the atmosphere, groundwater, and rivers, based on observational and literature data, and identifies three zones (brown, green and blue waters) in the coastal GOM and CSK with different productivity and carbon fluxes. Based on our model results, the potential primary production rate in the inner (brown water) zone are more than 2 (GOM) and 1.5 gC m−2 day−1 (CSK). In the middle (green water) zone, potential production is between 0.1 to 2 (GOM) and 0.3 to 1.5 gC m−2 day−1 (CSK). In the offshore (blue water) zone, productivity is less than 0.1 (GOM) and 0.3 (CSK) gC m−2 day−1. Through our model scenario results, overall oxygen demand in the GOM would increase approximately 21 % if we fail to reduce riverine N input, likely increasing considerably the area affected by hypoxia. Comparing the results from the U.S. with those from Korea shows the importance of considering both riverine and atmospheric inputs of nitrogen. This has direct implications for investigating how changes in energy technologies can lead to changes in the production of various atmospheric contaminants that affect air quality, climate and the health of local populations.
Predictability of Non-Phase-Locked Baroclinic Tides in the
Caribbean Sea
Authors: Zaron Edward D.
Published: May 2019

Abstract. The predictability of the sea surface height expression of baroclinic tides is examined with 96 hr forecasts produced by the AMSEAS operational forecast model during 2013–2014. The phase-locked tide, both barotropic and baroclinic, is identified by harmonic analysis of the 2 year record and found to agree well with observations from tide gauges and satellite altimetry within the Caribbean Sea. The non-phase-locked baroclinic tide, which is created by the time-variable mesoscale stratification and currents, may be identified from residual sea level anomaly (SLA) near the tidal frequencies. The predictability of the non-phase-locked tide is assessed by measuring the difference between a forecast – centered at T+36 hr, T+60 hr, or T+84 hr – and the model's later verifying analysis for the same time. Within the Caribbean Sea, where a baroclinic tidal sea level range of ±5 cm is typical, the forecast error for the non-phase-locked tidal SLA is correlated with the forecast error for the sub-tidal (mesoscale) SLA. Root-mean-square values of the former range from 0.5 cm to 2 cm, while the latter ranges from 1 cm to 6 cm, for a typical 84 hr forecast. The spatial and temporal variability of the forecast error is related to the dynamical origins of the non-phase-locked tide and is briefly surveyed within the model.
Brief communication: Full-field deformation measurement for uniaxial compression of sea ice using the digital image correlation method
Authors: Wang Anliang , Wei Zhijun , Chen Xiaodong , Ji Shunying , Liu Yu , Qing Longbang
Published: May 2019

Abstract. The study of the mechanical properties of sea ice benefits the
parameterization of sea-ice numerical models and the optimization of
engineering design. Deformation measurement of sea ice has been seen as the
essential foundation for the study of these properties. However, this
measurement has proved to be difficult due to the complex and nonhomogeneous
mechanical properties of sea ice. In this paper, we took advantage of DIC
(digital image correlation) to obtain the full-field displacement and strain
of sea-ice specimens in a uniaxial compression experiment. Full-field
deformations of sea ice under both vertical and horizontal loading were
measured. Different mechanical behaviors such as microcracks and failure
modes due to the anisotropic properties of sea ice were successfully
captured. The nonuniformity and local concentration of the strain field were
observed and analyzed. Additionally, we evaluated the displacement and strain
field of the specimens to verify the feasibility and accuracy of the method.
This successful application provides a convenient and powerful option for the
study of sea-ice mechanical properties including failure modes, nonlinear
behavior and crack propagation.

Abstract. Wake steering is a form of wind farm control in which turbines use
yaw offsets to affect wakes in order to yield an increase in total energy
production. In this first phase of a study of wake steering at a commercial
wind farm, two turbines implement a schedule of offsets. Results exploring
the observed performance of wake steering are presented and some
first lessons learned. For two closely spaced turbines, an approximate
14 % increase in energy was measured on the downstream turbine over a
10∘ sector, with a 4 % increase in energy production of the
combined upstream–downstream turbine pair. Finally, the influence of
atmospheric stability over the results is explored.

Published: May 2019

Trichomoniasis is a curable sexually transmitted infection (STI) that has been reported to be linked to exposure to human immunodeficiency virus (HIV), although few studies have described this association. The purpose of this study was to focus on the incidence of trichomoniasis in low-income women, its relation to HIV status, viral load levels and TCD4+ cell counts, among other risk factors, using an in vitro culture as a diagnostic test. A crosssectional study among 267 women (103 HIV-positive and 164 HIV-negative) was conducted in 2015. The overall prevalence of Trichomonas vaginalis (TV) infection was 6.4%. Among HIVpositive and HIV-negative women, the prevalence was 3.9% and 7.9%, respectively, yet these results were not statistically different (p=0.1878). The factors associated with TV infection were cigarette smoking (OR= 3.52), vaginal itching (OR=4.43) and bacterial vaginosis (BV) (OR= 5.29). HIV status, TCD4+ cell count and viral load were not associated with TV infection in this group. The prevalence rates found, lower than those observed in other studies, may be due to the fact that the women evaluated in the present study are part of a low-risk populationas well as the limited sample size of HIV positive women.

Authors: Wang Yanqun , Wang Boyuan , Xue Ze , Zhu Liyan
Published: May 2019

Impacts of different pH levels on different species of marine copepods, Calanoida copepod Schmackeria poplesia and Cyclopoida copepod Oithona similis were evaluated, and the alteration of key physiological processes of feeding and filtering were comparatively studies under controlled lab conditions. The optimal pH for O.similis and S.poplesia was 9.0 and 8.0 respectively, and they performed differently when exposed to different pH levels. For S. poplesia., the feeding and filtering rates increased steadily with the increment of pH at the range of 6.0~8.0, and reached the peak at pH 8.0. However, the rates decreased when pH was above 9.0. O.similis seemed more adaptive to the change of pH, and the increment was found in feeding and filtering rates at a range of 6.0~8.0. The maximus appeared at pH 9.0. compared to the other pH levels, the acidifying level of pH 6.0 presented the most obviously inhibition on feeding and filtering. Results in the present study would shed light on establishing the optimum culturing conditions for the cultivation of marine copepod.

When accounting for the granted funds, the researcher should go beyond the simple technical reporting, ensuring that the produced knowledge should be available to society in its most broad and disseminated way. This is only possible with the publication of the results of his/her work on a periodical of archival value, made available to the public in libraries or in the internet. Engenharia Térmica contributes to this effort by allowing for publication of scientific and technological work in the area of Thermal Sciences, which will find application in key areas to the world, such as Energy and Environment.Also, submission of work derived from the cooperation between university and industry, or originated directly from the industry’s own research and development department, is strongly encouraged.The present issue further contains expanded and revised papers that have originally been presented at ENCIT 2002 (9th Brazilian Congress of Thermal Engineering and Sciences). This has been a successful policy of Engenharia Térmica, which should be extended to other ABCM (Brazilian Society of Mechanical Sciences) national conferences, COBEM and CONEM,and to thematic events, such as, for example, Mercofrio and Conbrava, from Refrigeration.As in the past issues of Engenharia Térmica, two main sections classify the papers. Science contains papers related to the advancements of Thermodynamics, Fluid Mechanics and Heat and Mass Transfer, and to novel theories or advanced numerical and experimental methods. Technology is directed to technological contributions in Thermal Engineering, including the presentation of papers featuring technological innovations.

Public listed companies in Malaysia have been pressured tremendously to accept the engagement of Environment, Social and Governance (ESG), but the engagement is still low based on previous studies. ESG will enhance company financial performance, image as well as the ability to attract and retain the workplace which contributes to the market value in the economy. This shows that ESG engagement improve company brand image and reputation, increase customer loyalty and sales as well as productivity. Corporate governance is seen to be the key role to ensure that companies engage with ESG practices since it can enhance the value creation and improve financial performance. Even the present investors are bound to look for non-financial performance elements like corporate governance and environmental, social and governance (ESG) practices that the company engaged since it is an evidence of effective corporate governance. Based on today’s global and innovation-driven economy which also include social and environmental matters consisting of welfare distribution and growth, it is said that countries need to be more efficient in finding new ways to enhance the environmental policy promoting greater change and dynamics. Thus, they must find new ways to develop an innovation policy to emphasise the knowledge-driven economy on the capacity to adapt and adopt best practices, create, diffuse and transform innovation and knowledge. The absorptive capacity will recognise the ability of the individual and company in adopting the innovation which play an essential part in determining the characteristics of good corporate governance to ensure best ESG practices in the company. This paper examines the relationship between board capabilities and ESG practices through the mediating role of absorptive capacity. Board size, board diversity and board independent are the board capabilities that the paper investigates. Collection of information and data was from company's listed in FTSE4Good Bursa Malaysia from the year 2012 to 2016. The results from the regression analysis show that ESG practices have a significant relationship with board size, board diversity, board independence and absorptive capacity. On top of that, absorptive capacity is perceived to have influence on board diversity and board independence towards ESG practices. The results provide empirical evidence and guidance in identifying areas of problems in the current policy and amend it for a better policy in promoting sustainability.

Authors: Gonçalves Patrícia Graziela , Priori Angelo Aparecido
Published: May 2019

O artigo apresenta os resultados de uma pesquisa que objetivou analisar o pensamento jurídico acerca dos movimentos grevistas ocorridos no Brasil em meados do século XX, tendo como fonte artigos escritos por juristas e publicados na Revista Forense e na Revista dos Tribunais, entre os anos de 1953 e 1955. Para o desenvolvimento de nossas reflexões, partimos do pressuposto de que os acontecimentos sociais possuem reflexos importantes no âmbito jurídico, propiciando a interiorização de esquemas de percepção, apreciação e ação por parte dos diversos agentes jurídicos. Como resultado, identificamos os diferentes modos de percepção dos referidos movimentos sociais: as associações entre greve e guerra; as críticas ao seu sentido político; as suas desqualificações em termos legais; e também algumas defesas.

The purpose of the study was to investigate the knowledge, attitude and practices of female tertiary students at the University of Namibia regarding contraception. The objective of the study was to assess and describe the knowledge, attitudes and practices of University of Namibia Education students at Rundu campus, regarding contraception with a view to make recommendations based on the findings of the study. A quantitative, descriptive cross-sectional design was used and a total of 220 female tertiary students from Rundu Campus were selected using simple random sampling. Data was collected from participants by the use of a self-administered questionnaire. Findings from this study showed amongst other that majority (80%) 166 showed poor practices towards contraception. However, the study showed that (91%) 202 has positive attitude regarding contraceptives and that this greatly contributes to high rate of unintended pregnancies as well as Sexually Transmitted Infections among them. It is recommended that in order to prevent unintended pregnancies as well as high incidences of Sexually Transmitted Infections among tertiary students, the Ministry of Health and Social Services must introduce a regular reproductive health outreach programme on campus, or establish a clinic on campus. Neglecting youth’s contraceptive needs contributes to high rate of unintended pregnancies, Sexually Transmitted Infections, HIV/AIDS and, indirectly; maternal mortality.
