El futuro morfológico en las lenguas iberorromances
Authors: Lara Bermejo Víctor 
Published: April 2020

AbstractThe future tense in the Ibero-Romance languages swings between temporal and modal readings. Despite the fact that all the varieties of the Iberian Peninsula possess various strategies that compete with the morphological future, there is no consensus on pinpointing which alternative refers to each of the possible readings. The only thing all authors agree on is the current decline of the morphological future tense with temporal value. In this article, current dialect data of the Romance languages of the Iberian Peninsula have been collected with the aim of analysing the contemporary and oral usage of this verbal tense in order to verify whether it still maintains its temporal or modal uses, or whether, as the latest research points out, it has become an evidentiality strategy.
Present/future tense variation in contemporary Italian
Authors: Hoff Mark 
Published: April 2020

AbstractAccording to normative descriptions of Italian future-framed adverbial clauses, the future tense is the only option (Quando verrai[F],ti presterò il libro‘When you come, I’ll lend you the book’). However, the present tense may also be used (Quando vieni[P],ti presto il libro). I demonstrate that choice and acceptance of the present in future-framed adverbials are conditioned by the speaker’s presumption of settledness; that is, in every future world compatible with the speaker’s beliefs the eventuality necessarily occurs. The data come from an online questionnaire consisting of a forced-choice and an acceptability judgment task completed by 429 native speakers of Italian, and were analyzed using mixed-effects regression. Results show that the present is chosen most and rated highest when the future eventuality is presumed settled ([+certain, +immediate, +temporally specific]). These findings demonstrate that speakers use the present to express confidence in the realization of future eventualities.

Published: April 2020

Abstract
The use of diesel engines in small passenger cars began to be common by vehicle manufacturers. The direct contact with humans with all the consecquencies is one of the important things to be considered in the vehicle design aspect of vibration. This research of the vibration propagation characteristics on passenger car structure has been done. Eventhough is not so many been done, especially on monocoque body structures types, in the world of the automotive industry, This research was conducted by tracking the measuring point which is considered to have a relatively large vibration response compared to other points on the body. Retrieval of vibration data in the form of RMS velocity amplitudes and of the frequency spectrum data at the measuring point. The RMS velocity amplitude data is obtained and then refered to the IRD Severity Chart vibration standard to determine the vibration severity level, as well as the transfer path analysis is performed to determine the vibration reduction that occurs in the vehicle structure. Spectrum analysis is also carried out to see what excitations that provide vibrational responses to the vehicle body structure. From the measurement and analysis results, the characteristics of vibration propagation on the monocoque body structure are determined, which the vibration response of the monocoque body structure as a whole can be concluded.

Abstract
Exposure to fine particulate matter (PM2.5) is a leading contributor to the disease burden in India, largely due to widespread household solid fuel use. The transition from solid to clean fuels in households has the potential to substantially improve public health. India has implemented large initiatives to promote clean fuel access, but how these initiatives will reduce PM2.5 exposure and the associated health benefits have not yet been established. We quantified the impacts of a transition of household energy from solid fuel use to liquefied petroleum gas (LPG) on public health in India from ambient and household PM2.5 exposure. We estimate that the transition to LPG would reduce ambient PM2.5 concentrations by 25%. Reduced exposure to total PM2.5 results in a 29% reduction in the loss of healthy life, preventing 348 000 (95% uncertainty interval, UI: 284 000–373 000) premature mortalities every year. Achieving these benefits requires a complete transition to LPG. If access to LPG is restricted to within 15 km of urban centres, then the health benefits of the clean fuel transition are reduced by 50%. If half of original solid fuel users continue to use solid fuels in addition to LPG, then the health benefits of the clean fuel transition are reduced by 75%. As the exposure–outcome associations are non–linear, it is critical for air pollution studies to consider the disease burden attributed to total PM2.5 exposure, and not only the portion attributed to either ambient or household PM2.5 exposure. Our work shows that a transition to clean household energy can substantially improve public health in India, however, these large public health benefits are dependent on the complete transition to clean fuels for all.
From individual to whole: the practical value of spatial phenomenon transparency in the building renewal
Authors: Xie Guangyi , Wang Minjuan 
Published: April 2020

Abstract
With the development of modern life and production mode, the functions and facilities become more diverse in the process of architectural renewal, which leads to the contradiction between the diversified realistic demands and the overall order of architecture. Furniture is the main factor that affects the function and also the important element of facilities.The contradictions of formal logic between multiple furniture and architectural order include the expression of individual comfort and uniqueness.As a means of organizing form and space, phenomenal transparency transcends the limitation of historical style in visual mechanism, and provides methodological enlightenment for the contradiction resolution of individual differences and overall order through multiple interpretations of the combination of image and background. This paper attempts to apply the phenomenon transparency to the architectural renewal, refining three characteristics that contain front view, figure-ground transposition, and level progression. This paper puts forward a design method to solve the contradiction between the diversity of forms and the integrity of buildings after the new furniture and facilities are put in and finally evaluates the effectiveness and applicability of the method with practical cases.

Study on the exploitation, utilization and cooperation of geothermal energy between Iceland and China
Authors: Zhang Huan , Meng Wei , Zhao Fang 
Published: April 2020

Abstract
Iceland has a long history of geothermal resource utilization and gains successful experiences in the exploitation and management of geothermal resources. Although China has abundant geothermal resources, the utilization rate is not high, and its management mechanism is not perfect yet. There is still much to improve. Through the comparison of geothermal resource utilization and management between Iceland and China, combining with the evolutionary game model of energy cooperation, this paper draws a conclusion: although both sides can gain corresponding benefits by strengthening energy cooperation, the urgency of cooperation between them is not very strong and the cooperation is in a still mode. With the increasing proportion of China’s clean energy usage and pressure on traditional energy security, as well as the promotion of China-Iceland free trade zone in bilateral economic and trade cooperation, their willingness for energy cooperation is very likely to be strengthened. Therefore, both sides should be forward-looking when formulating energy strategies, establish a geothermal enterprise alliance, share knowledge and information, actively deepen the co-development of unconventional geothermal energy.

Published: April 2020

Abstract
In this work, a study of orthophosphate detection technique in the aquatic system has been conducted. The detection technique used in this study was Diffusive Gradients in Thin Films (DGT) with Fe-Chitosan-Bentonite (Fe-CSBent) biocomposite as the binding agent. The phosphate species diffused through the polyacrylamide gel and then bound by Fe-CSBent as the binding agent on the binding layer. The adsorption of phosphate by Fe-CSBent is through electrostatic attraction, inner sphere complexation, and ion-exchanged. The synthesized Fe-CSBent biocomposite was characterized using Fourier Transform Infrared (FTIR), Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (EDS) and X-Ray Diffraction (XRD) analysis, and the synthesized diffusive gel and binding gel were characterized using FTIR analysis. In this experiment, we examined the DGT-Fe-CSBent capability in orthophosphate binding with parameters such as the deployment time, pH of the solution and the presence of co-existent anion i.e. sodium tripolyphosphate (STPP). The mass of bound orthophosphate can be calculated after eluted the binding gel with acid and then measured with the molybdenum blue method using UV-Vis spectrophotometry. Based on the experiment, DGT-Fe-CSBent bound the orthophosphates more efficiently in concentration of 2.2970 μg/mL with 90.208 % efficiency, compared to DGT-CSBent in concentration of 1.7333 μg/mL with 79.874 % efficiency. It was also known that the presence of STPP influenced the amount of orthophosphate concentration bound by Fe-CSBent in the binding gel. DGT-Fe-CSBent device that was made to be selective in predicting bioavailable phosphate, but the presence of other phosphate species such as sodium tripolyphosphate may be influenced orthophosphate bound by DGT.

Authors: Putrananda A T , Nurani D A , Krisnandi Y K 
Published: April 2020

Abstract
This study presents a partial oxidation of biomethane from anaerobic organic waste of cow dung (83.7 % of methane and 16.3 % of oxygen) to methanol using modified cobalt and iron metal oxide-hierarchical ZSM-5 catalysts. Hierarchical ZSM-5 was synthesized using double template methods with tetrapropylammonium hydroxide (TPAOH) and dimethyl diallyl ammonium chloride acrylamide copolymer (PDDAM) as the first and secondary templates, respectively. The as-synthesized ZSM-5 materials were characterized with Scanning Electron Microscopy-Energy Dispersive X-Ray Spectroscopy (SEM-EDS), Fourier Transform Infrared (FTIR), X-Ray Diffraction (XRD), and the results show the similarities of physicochemical properties with standard ZSM-5 materials. The hierarchical ZSM-5 was then modified with cobalt or iron oxides through impregnation with incipient wetness. The results of XPS analysis show that the impregnated cobalt and iron metal oxide are Co3O4 and Fe2O3, respectively. While the AAS analysis indicates that the metal content in Co3O4/ZSM-5 and Fe2O3/ZSM-5 are 2.1 % (Co) and 2.4 % (Fe), respectively. The partial oxidation of bio-methane to methanol was carried out in an atmospheric fixed batch reactor, c.a. 200 mL, with biomethane to N2 ratio of 0,2:2 (in bar). The results of application using biomethane show the hierarchical Fe2O3/ZSM-5 catalyst has higher methanol yield (17.61 %), compared to the yield by using hierarchical Co3O4/ZSM-5 (10.99 %). In addition, no side product is detected after reaction. Thus, it can be concluded that Fe2O3 is more active than Co3O4 as catalyst and biomethane can be utilized as source in this partial oxidation reaction.
