Authors: Yu Shan , Hou Qiang , Sun Jiayi
Published: March 2020

Climate change and greenhouse gas emission reduction have become common concerns. Carbon trading systems and low-carbon cost subsidies are important emission reduction measures. Impacts of a combination of the two policies on micro-supply chain emission-reduction technology investment have become a focal research area. This paper: (1) constructs an investment game model based on cost-sharing coordination under a cost subsidy between manufacturers and retailers; (2) examines the equilibrium strategy and optimal results according to the interests and game relationships of each stakeholder; and (3) explores the effectiveness of supply chain enterprise behavior based on cost-sharing coordination under the cost subsidy. This paper uses a numerical simulation method to compare the path evolution under different scenarios and to analyze the sensitivity of parameters, identifying the influence of various parameters on the general structure and pathways. The study finds that the cost subsidy policy has a regulatory effect on enterprise emission reduction investment and enterprise profit under a carbon trading system, and the difference caused by the regulation effect is enhanced over time. The study also shows that the dynamic path of each parameter strengthens over time.

Published: March 2020

Through an active administration approach, the Local Living Security Commission (LLSC) has provided relief to protect the poor strata and reinforce the distribution of entitlements. However, the absence of a system to monitor operational performance makes it difficult to manage it efficiently. The purpose of this study is to find ways to strengthen and efficiently operate the functions of the LLSC through priority analysis of its operation. To this end, the analytic hierarchy process (AHP) was conducted based on the results of the focus group interview to derive priorities for the operation of the LLSC. The variables used in the AHP analysis included regional conditions, operational performance, organizational method, and network. The result of the analysis revealed, first, that the performance of the committee has increased due to a joint evaluation or verification survey conducted at the end of each year, second, that the creation of a budget for the organization and the operation of an independent LLSC is necessary, and third, that operational performance is the most important, followed by organizational method, network, and regional conditions. Therefore, a system for monitoring performance should be established to improve the operation performance of the LLSC. Additionally, it is necessary to establish an independent LLSC and secure the budget for each city and county. It should be possible to provide feedback on operations through regular priority analysis.
Alternative Proposals to Measure Consumer Ethnocentric Behavior: A Narrative Literature Review
Authors: Jiménez-Guerrero José Felipe , Pérez-Mesa Juan Carlos , Galdeano-Gómez Emilio
Published: March 2020

CETSCALE (Consumer Ethnocentrism Tendencies Scale), the scale developed by Shimp and Sharma in 1987 to study consumer ethnocentric behavior, has received preferential use in the literature, with numerous replications carried out in countries on all continents. Although it was proposed as a 17-item scale along with a smaller version of only ten items, studies that use only a part of these have been become increasingly common. To some extent, this practice responds to the multidimensional behavior of CETSCALE, as can be widely confirmed. It is for this reason that a growing consensus is in favor of reviewing the scale as a tool to measure ethnocentrism, made evident by the appearance of new alternative scales. CEESCALE and CES are two of the most recent proposals, which were developed with a similar number of items but grouped into a number of clearly defined dimensions, providing more robust results.

Authors: Ju Chunhua , Gu Qiuyang , Fang Yi , Bao Fuguang
Published: March 2020

User influence has always been a major topic in the field of social networking. At present, most of the research focuses on three aspects: topological structure, social-behavioral dimension, and topic dimension and most of them ignore the difference between the audience. These models do not consider the impact of personality differences on user influences. To meet this need, this paper introduces the personality traits factor and proposes a user influence model which integrates personality traits (IPUIM) under a strong connection. The user influence measurement is constructed through the information dimension, structural dimension, and user behavioral dimension. The personality report of the user group is obtained by means of NEO-PI-R (The big five personality inventory, Chinese edition) and machine learning method, and it is integrated into the user influence model. The experiment proves that the model proposed in this paper has good accuracy and applicability in measuring user influence, and can effectively identify the key opinion leaders of different personality trait clusters.

Authors: Pei Yu-Long , He Yong-Ming , Ran Bin , Kang Jia , Song Yu-Ting
Published: March 2020

In China, the maximum design speed of highways is 120 km/h, which first appeared in the Highway Engineering Technical Standard (Trial) in 1951. However, vehicle performance, road design, and construction technology have been greatly improved over the past 68 years. To adapt to the development demands of highway design speeds above 120 km/h in the future, it is urgent to study superhighway alignment design theory. Therefore, the horizontal alignment security design theory of superhighways was developed in this paper. First, the definition, classification, and construction mode of a superhighway and suitable vehicles of different grades are presented. Then, the lengths of straight lines were limited to reduce driving fatigue. Next, the minimum radii of circular curves were calculated based on driver characteristics and stress analysis of operating vehicles. Finally, the minimum lengths of transition curves were calculated based on the centrifugal acceleration of the operating vehicles, the travel time, and the passenger visual characteristics. The calculation and analysis results show that the superhighway linear features conform to the vehicle operating characteristics, and can ensure the safety of driving.
Urban Resilience to Flooding: Triangulation of Methods for Hazard Identification in Urban Areas
Authors: Almeida Maria do Céu , Telhado Maria João , Morais Marco , Barreiro João , Lopes Ruth
Published: March 2020

The effects of climate dynamics on urban areas involve the aggravation of existing conditions and the potential for emergence of new hazards or risk factors. Floods are recognized as a leading source of consequences to society, including disruption of critical functions in urban areas, and to the environment. Consideration of the interplay between services providers ensuring urban functions is essential to deal with climate dynamics and associated risks. Assessment of resilience to multiple hazards requires integrated and multi-sectoral approaches embracing each strategic urban sector and interactions between them. A common limitation resides in the limited data and tools available for undertaking these complex assessments. The paper proposes a methodology to undertake the spatial characterization of the flood related hazards and exposure of both essential functions and services providers in urban areas, in the context of limitations in data and in ready-to-use tools. Results support the resilience assessment of these hazards, taking into account interdependencies and cascading effects. The approach is applied to Lisbon city as the study case. Results are promising in demonstrating the potential of combining data and knowledge from different sources with dual modelling approaches, allowing us to obtain trends on the magnitude of effects of climate scenarios and to assess potential benefits of adaptation strategies. Quantification of the effects is reached, but results need to be assessed together with the underlying levels of uncertainty. The methodology can facilitate dialogue among stakeholders and between different decision levels.
Crop Pollination in Small-Scale Agriculture in Tanzania: Household Dependence, Awareness and Conservation
Authors: Sawe Thomas , Nielsen Anders , Eldegard Katrine
Published: March 2020

Global economic value of agriculture production resulting from animal pollination services has been estimated to be $235–$577 billion. This estimate is based on quantification of crops that are available at the global markets, and mainly originates from countries with precise information about quantities of agriculture production, exports, and imports. In contrast, knowledge about the contribution of pollinators to household food and income in small-scale farming at local and regional scales is still lacking, especially for developing countries where the availability of agricultural statistics is limited. Although the global decline in pollinator diversity and abundance has received much attention, relatively little effort has been directed towards understanding the role of pollinators in small-scale farming systems, which feed a substantial part of the world’s population. Here, we have assessed how local farmers in northern Tanzania depend on insect-pollinated crops for household food and income, and to what extent farmers are aware of the importance of insect pollinators and how they can conserve them. Our results show that local farmers in northern Tanzania derived their food and income from a wide range of crop plants, and that 67% of these crops depend on animal pollination to a moderate to essential degree. We also found that watermelon—for which pollination by insects is essential for yield—on average contributed nearly 25% of household income, and that watermelons were grown by 63% of the farmers. Our findings indicate that local farmers can increase their yields from animal pollinated crops by adopting more pollinator-friendly farming practices. Yet, we found that local farmers’ awareness of pollinators, and the ecosystem service they provide, was extremely low, and intentional actions to conserve or manage them were generally lacking. We therefore urge agriculture authorities in Tanzania to act to ensure that local farmers become aware of insect pollinators and their important role in agriculture production.

Published: March 2020

The aim of this study was twofold: (1) to assess the performance accuracy of support vector machine (SVM) models with different kernels to predict rock brittleness and (2) compare the inputs’ importance in different SVM models. To this end, the authors developed eight SVM models with different kernel types, i.e., the radial basis function (RBF), the linear (LIN), the sigmoid (SIG), and the polynomial (POL). Four of these models were developed using only the SVM method, while the four other models were hybridized with a feature selection (FS) technique. The performance of each model was assessed using five performance indices and a simple ranking system. The results of this study show that the SVM models developed using the RBF kernel achieved the highest ranking values among single and hybrid models. Concerning the importance of variables for predicting the brittleness index (BI), the Schmidt hammer rebound number (Rn) was identified as the most important variable by the three single-based models, developed by POL, SIG, and LIN kernels. However, the single SVM model developed by RBF identified density as the most important input variable. Concerning the hybrid SVM models, three models that were developed using the RBF, POL, and SIG kernels identified the point load strength index as the most important input, while the model developed using the LIN identified the Rn as the most important input. All four single-based SVM models identified the p-wave velocity (Vp) as the least important input. Concerning the least important factors for predicting the BI of the rock in hybrid-based models, Vp was identified as the least important factor by FS-SVM-POL, FS-SVM-SIG, and FS-SVM-LIN, while the FS-SVM-RBF identified Rn as the least important input.
Common and Strain-Specific Post-Translational Modifications of the Potyvirus Plum pox virus Coat Protein in Different Hosts
Authors: Hervás Marta , Ciordia Sergio , Navajas Rosana , García Juan Antonio , Martínez-Turiño Sandra
Published: March 2020

Phosphorylation and O-GlcNAcylation are widespread post-translational modifications (PTMs), often sharing protein targets. Numerous studies have reported the phosphorylation of plant viral proteins. In plants, research on O-GlcNAcylation lags behind that of other eukaryotes, and information about O-GlcNAcylated plant viral proteins is extremely scarce. The potyvirus Plum pox virus (PPV) causes sharka disease in Prunus trees and also infects a wide range of experimental hosts. Capsid protein (CP) from virions of PPV-R isolate purified from herbaceous plants can be extensively modified by O-GlcNAcylation and phosphorylation. In this study, a combination of proteomics and biochemical approaches was employed to broaden knowledge of PPV CP PTMs. CP proved to be modified regardless of whether or not it was assembled into mature particles. PTMs of CP occurred in the natural host Prunus persica, similarly to what happens in herbaceous plants. Additionally, we observed that O-GlcNAcylation and phosphorylation were general features of different PPV strains, suggesting that these modifications contribute to general strategies deployed during plant-virus interactions. Interestingly, phosphorylation at a casein kinase II motif conserved among potyviral CPs exhibited strain specificity in PPV; however, it did not display the critical role attributed to the same modification in the CP of another potyvirus, Potato virus A.
Vortex Express Method for Parameter Determination Thermoelectric Materials
Authors: Ashcheulov A. A. , Lavrenjuk D. A. , Romanjuk I. S.
Published: March 2020

The method is based on the possibility of determining the heat loss of electric power during the flow of Foucault eddy currents in the volume of a thermoelectric sample, placing in the field of action of the ferrite core an inductor through which electric currents that are symmetrical and asymmetric in nature flow sequentially in time.
Mathematical expressions are obtained for the coefficients of electrical conductivity σ, thermal conductivity ϰ, thermo-emf α and thermoelectric figure of merit Z. Minimization of the error of the proposed method, carried out by computer simulation of the physical processes occurring in the sample using appropriate programs, showed that the operating frequency of the device measuring sensors should be located in the range of 36 ÷ 250 kHz, and the electric current flowing through it — taking into account the inequality  qф/П/ qф/ qϰ  >  10. The magnetic field induction ratio in terms of components is selected from the condition В0/В > 8.6, which corresponds to the conditions of minimal impact on the parameters of the sample by galvanic thermomagnetic phenomena.
The block diagram of a device for non-contact measurement of symmetric σс and asymmetric σа components of the electrical conductivity of thermoelectric materials consists of: 1 — SV switch block; 2 — electronic switch; 3 — auto generator; 4 — AC amplifier; 5 — synchronous detector; 6 — DC amplifier; 7 — pulse generator; 8 — signal processing unit; 9 — indicator device; 10 — DC indicator; 11 — correction unit; FR1, FR2.
Measurement of the parameters of the thermoelectric sample based on Bi-Te-Se-Sb crystals showed that the real error of the proposed method is 2  %. This indicates that the eddy current method can be successfully used to determine the main parameters of thermoelectric materials.
The use of this method allows solving the relevant problem of avtomazation of the process of monitoring and sorting out thermoelectric ingots, billets and parts.
Mathematical Models of Conservative Objects of Control

Published: March 2020

Trend analysis and record charts different technological parameter in the heat power, chemical and oil refining industry showed, that most of them are oscillatory in nature. In order to reduce the amplitude of the oscillations, filters are used, and for the actual value of the measured quantity — their average value. Research has found, that the oscillatory-pulse nature of trends and diagrams of measured values is observed in multi-parameter technological objects of control, which have valve valve strapping on both input and output material, heat or energy flows. It is shown that valve-type regulating organs, which are used in automatic control systems, together with the technological apparatus create partial objects, which work on a conservative type. This creates new dyna­mic objects with three or more private conservative systems, which together create a complex multi-para­meter technological control object with the oscillatory-pulse nature of the measured parameters. It was found that in many cases for such complex objects of control the average value of the measured parameter, defined with the trend, can differ significantly from its actual value. This leads to the appearance of significant measurement errors, and consequently, to an incorrect assessment of the quality of manufactured pro­ducts. The task is to study the causes of the appearance of such vibrational-pulse systems, their properties, devia­tions of average readings along the trend from the actual value of the measured parameter, and also develop methods for reducing measurement errors. The paper presents mathematical and physical models of such conservative control systems, obtained on the basis of the theory of rheological transformations, as well as the results of their research. It is shown that the vibrational-pulse trends of the measurement parameters are a set of angular frequencies of private objects, the sum of which creates an oscillatory-pulse form of the signals of the measuring parameters.

Authors: Khorlo N. F.
Published: March 2020

A comprehensive analysis of the concept “sector”, as one of the main components of the certification area of a specialist in non-destructive testing (NDT) in accordance with the requirements of the international standard EN ISO 9712, was carried out. Features and differences of the lists of sectors regulated by regulatory documents that establish the requirements for certification of NDT personnel are considered in the voluntary (DSTU EN ISO 9712) and legislatively regulated (NPAOP 0.00-1.63-13) areas of Ukraine. The features of the areas of accreditation of Personnel Certification Bodies (OSB) in the field of non-destructive testing of Ukraine and some countries of the European Union are considered. The analysis of sectors with which non-destructive testing personnel is certified was performed. Personnel certification bodies accredited by the National Accreditation Agency of Ukraine (NAAU) and national accreditation bodies of the Great Britain, Germany and Nordic countries in accor­dance with the requirements of the international standard EN ISO / IEC 17024. The differences in product and manufacturing sectors re­gulated by the standard EN ISO 9712 and established by the areas of accreditation of PCB in the field of non-destructive control of Ukraine and selected European countries. The basic principles are stated in accordance with which an additional (national) sector should be created. On the example of the analysis of differences in the production sectors “production” and “control before and during ope­ration, including production” according to EN ISO 9712, various aspects of non-destructive testing that affect the criteria for the formation of additional (national) production sectors were considered. The possibility and appropriateness of introducing national sectors into the certification procedures of Personnel Certification Bodies for non-destructive testing in Ukraine are considered.

Published: March 2020

Taking into account large number of questions coming from the metrological services of enterprises and organizations is considered the classification of measuring instruments to legally regu­lated measuring instruments, government regulation, which applied to them in order to assurance the uniformity of measurement and traceability, according to the Law of Ukraine «On met­rology and metrological activity», and requirements relating to conformity assessment, verification and calibration of measuring instruments.
Having analyzed the measurement requirements and measurement results established by the provisions of the law, it is proposed to divide measuring instruments used in the field of legal metrology into the groups.
For the above mentioned groups of measuring instruments, which are used in the field of legal metrology, a scheme has develo­ped, that illustrates the processes of government regulation, namely: government regulation of measuring instruments during placing on the market and putting into use and government regulation of measuring instruments during using. 
The scheme shows that the placing on the market and putting into use of legally regulated measuring instruments is possible if their conformity assessment is carried out.  During using legally regulated mea­suring instruments are subject to periodic and post-repair verification.
Calibration under the law is a voluntary procedure. However, measurement results cannot be applied in the field of legal metrology if errors of the measurement results or the uncertainty of the mea­surement results are unknown. Uncertainty of the measurement results is established only during the measuring instruments calibration.

The subject is the anti-corruption standards of legal regulation of "external" activities of public officials. Research methodology is shaped by both general scientific and special methods of scientific research. The basic is dialectical analysis, semantic, comparative-legal, logical-legal, modeling, forecasting are also used.

The following conclusion can be made. Anti-corruption standardization of legal regulation of "external" activities of public servants helps to systematize, unify the principles of such regulation, and increase the efficiency of enforcement. It is advisable: a) awareness of the importance of "external" activities of public servants for the latter (their personal growth, personal realization), and for the public service as a whole (including the formation and improvement of the quality of human resources), consolidation of official norms-definition of the "external activity of public servants" as any activity of the latter out of office regardless of place, time, form, payment; b) introduction of a "mixed" model of legal regulation of "external" activity of public servants, with a combination of prohibition (business in all manifestations) and restrictions (with clear definition of criteria); c) unification of the principles of regulation of "external" activity of public employees and their concentration in the "basic" anti-corruption legislative act, alignment with the provisions of the legislation on public service; d) harmonization of the provisions on "external" activities of public servants with the legislation on declaring the income received from any sources outside the place of public service; e) to introduce the notification of the direct supervisor at the place of public service about "external" activity; f) the introduction of relevant, unlawful acts committed in connection with violations of the law on "external" activity by public officials, sanctions (penal or personal property).
Self-Regulated Learning and Academic Procrastination as Predictors of Smartphone Addiction among Second Year-Middle School Learning Disabled Students
Authors: Ali Eissa Saad Mourad
Published: March 2020

This study aimed to investigate the combined effects of Self-Regulated Learning (SRL) and Academic Procrastination (AP) on Smartphone Addiction (SA). It also aimed at investigating the relative contribution of SRL and academic procrastination to SA among second year- middle school learning disabled students. Moreover, it sought to explore if there were correlations between and among SRL and AP on SA. Quantitative survey research was employed. 68 students from the four schools were selected. The results revealed that there were correlations between and among SRL, AP and SA. Both SRL and AP contributed to the prediction of SA. AP is a more potential predictor than SRL. The results raise our awareness of the negative impact of SA upon students as students who are supposed to be of no risk for SA could use high SRL strategies. Additionally, students who are used to using smartphone excessively are rarely able to attain high academic achievement, and may delay doing their assigned homework.

Backgrounds: Serum OC and ssCTX are correlated with BMD and have early changes under antiresorptive therapies. This study was aimed to find correlations between serum OC, sCTX and BMD changes in women over 45 and evaluated early changes of the two markers in postmenopausal osteoporotic women with Fosamax plus therapy.
Materials and Methods: Cross-sectional and prospective study. 142 women over 45 were tested for serum OC and sCTX and determined BMD at lumbar spine and femur neck. 37 postmenopausal osteoporotic women of the group were treated with Fosamax plus therapy.
Results: OC and sCTX showed negative correlation with BMD of lumbar spine and femur neck in all of women over 45. The correlation between sCTX and BMD of femur neck was not significant. The lowest values of OC and sCTX to predict bone loss in non-osteoporotic women were 14.46ng/ml (ss = 76.1%, sp = 40%) and 396.25pg/ml (ss = 66%, sp = 52%). The decreasing rates of serum OC and sCTX after 3 and 6 months with Fosamax plus therapy were 41.6%, 55% (p ˂ 0.0001) and 78.3%, 72% (p ˂ 0.0001), respectively. Slow increasing rates of BMD at two sites were 4.2% (p ˂ 0.001) and 3.6% (p ˃ 0.05), irrespectively.
Conclusions: OC and sCTX were inversely correlated to BMD of lumbar spine and femur neck in all of women over 45. The lowest values of OC and sCTX to predict bone loss in non-osteoporotic women were 14.46ng/ml and 396.25pg/ml. Serum OC và sCTX decreased early in comparision to BMD improvement in postmenopausal osteoporotic women with Fosamax plus therapy.

The paper considers the description of phenomena in the own outboard atmosphere of spacecraft observed in the space experiment on the creation of the solar eclipse during the joint Soyuz–Apollo mission. It is shown that the transfer of solar radiation via gas-dust environment of own outboard atmosphere detected by the luminosity emanating from the shadow region outboard of the Apollo spacecraft when creating an artificial solar eclipse is an experimental result that confirms the theoretical conclusions on the similar exposure to radiation of the spacecraft with the nuclear power unit placed in the shadow of the radiation safety unit.

La tendencia a la masificación de la cobertura de la educación superior en América Latina
Authors: Rama Claudio
Published: March 2020

El presente artículo analiza las causas del proceso de masificación de la educación superior en América Latina en el marco de la expansión educativa, de la democratización social y de las demandas de formación de los hogares. Detalla las tendencias generales del proceso y sugiere nuevas formas de clasificación de las diversas categorías del acceso. Examina tanto algunas de las particularidades de los nuevos tipos de estudiantes cuya inserción universitaria deriva de la expansión de la cobertura, como las implicancias del proceso de masificación sobre la construcción de nuevas formas de desigualdad educativas y la persistencia de las inequidades sociales.

Os dados obtidos revelam níveis muito significativos neste grupo de profissionais do ensino.
Thin-films microstructuration through photolithography

Published: March 2020

In recent years, micro and nanotechnology have undergone a rapid development due to their applications in different scientific areas such as metaphotonics, an emerging branch of optics that studies the interaction of light with micro and nanostructured metamaterials. Our particular interest is the development of integrated metaphotonic devices for lab-on-a-chip biosensing applications. A widely used technique for the manufacture of integrated optical devices is photolithography, which is based on the processing of UV-light-sensitive photoresists to create masks for the deposition of thin films and generate the desired devices. In this contribution, we present an experimental methodology for the patterning of plasmonic waveguides using a photolithography system for printing SU-8 photoresist masks on glass substrates. We show the necessary parameters to optimize the photoresist printing (beam waist, focal distance and fluence) under normal conditions and the characterization of the samples through atomic force microscopy. Due to the aspect ratio between the width of the waveguides and thickness of the photoresist, the obtained results approach us to the development of multilayered systems for new integrated metaphotonic devices.
Determinación de horarios de aberturas en una vivienda de construcción masiva
para su corrección térmica interior

Currently the choice of massive construction models is
the alternative with greater recurrence to acquire a house
in warm humid climate in Mexico, however, much of this
is not adapted to its climatic environment and causes
thermal discomfort in the user because of the internal
environment generated as response of the characteristics
of its architectural envelope. To correct in a short time
the effect of thermal discomfort, the user usually
employs mechanized climatizations solutions such as
fans or air conditioners. It was proposed the use of
schedule for opening hours in the architectural envelope
in a warm humid climate, mainly in windows, as a
strategy to correct the internal thermal environment,
considering its advantages as the immediate application
and easy implementation, in contrast to some
architectural or physical modification of the envelope.
Dry bulb temperature and relative humidity
measurements were made in a massive construction
model to determine its thermal performance in the hottest
month of the year. Subsequently, simulations were made
with EnergyPlus to determine suitable opening times to
correct the thermal environment by prolonging the hours
of interior comfort when compared with the original
interior thermal performance of the envelope.
Propuesta de materiales termoaislantes para desarrollo de casa-habitación adecuada a cambios climáticos con eficiencia energética

The condition of climate change is attributed directly or
indirectly to activities related to the human being, as a
more transcendental effect the increase of temperature is
highlighted. Such a condition is not taken into account in
the development of current constructions, so it is sought
to propose the use of thermal insulating materials that
will give a thermal comfort to the user and a reduction of
energy use, which in turn will be an environmental
advantage. There are various types of thermal insulating
materials, however, it is proposed to be sustainable, as it
is intended not to contribute to climate change and to
meet the appropriate specifications of the building
envelope, in order to ensure the users comfort of current
and future dwellings, different factors, such as
orientation, as well as specific parameters, will be taken
into account as part of the development of the
aforementioned ones. The construction development of
the current house-room does not take into account the
continuous thermal alterations that occur by the
continuous climate change, ignoring the basic needs of
the thermal comfort of the user; so sustainable materials
are recommended, which meet thermoinsulating
properties without causing an environmental impact.

Published: March 2020

Agriculture in Mexico is an economic activity that allows for the livelihood of the most vulnerable families. However, the economic development of producers is reduced by the energy costs generated at work. For this reason, a prototype of Pelton turbine specially designed to take advantage of the natural fall of water was developed; in this way, clean energy is used for the same agricultural activity. The prototype results in a low-cost solution to reduce energy costs for small Mexican agricultural producers. The prototype is designed for a non-industrial water affluent but natural fall, the prototype was field tested, measuring performance results and having a substantial contribution to possible energy saving.
