An operational approach to forecast the Earth’s radiation belts dynamics
Authors: Bernoux Guillerme , Brunet Antoine , Buchlin Éric , Janvier Miho , Sicard Angélica
Published: November 2021

The Ca index is a time-integrated geomagnetic index that correlates well with the dynamics of high-energy electron fluxes in the outer radiation belts. Therefore, Ca can be used as an indicator for the state of filling of the radiation belts for those electrons. Ca also has the advantage of being a ground-based measurement with extensive historical records. In this work, we propose a data-driven model to forecast Ca up to 24 h in advance from near-Earth solar wind parameters. Our model relies mainly on a recurrent neural network architecture called Long Short Term Memory that has shown good performances in forecasting other geomagnetic indices in previous papers. Most implementation choices in this study were arbitrated from the point of view of a space system operator, including the data selection and split, the definition of a binary classification threshold, and the evaluation methodology. We evaluate our model (against a linear baseline) using both classical and novel (in the space weather field) measures. In particular, we use the Temporal Distortion Mix (TDM) to assess the propensity of two time series to exhibit time lags. We also evaluate the ability of our model to detect storm onsets during quiet periods. It is shown that our model has high overall accuracy, with evaluation measures deteriorating in a smooth and slow trend over time. However, using the TDM and binary classification forecast evaluation metrics, we show that the forecasts lose some of their usefulness in an operational context even for time horizons shorter than 6 h. This behaviour was not observable when evaluating the model only with metrics such as the root-mean-square error or the Pearson linear correlation. Considering the physics of the problem, this result is not surprising and suggests that the use of more spatially remote data (such as solar imaging) could improve space weather forecasts.

Enhancement of hydrogen radical density in atmospheric pressure plasma jet by a burst of nanosecond pulses at 1 MHz
Authors: Huang Bangdou , Zhang Cheng , Sun Hao , Sorokin Dmitry A , Tarasenko Victor F , Shao Tao
Published: November 2021

The generation and enhancement of active species in non-thermal plasmas are always decisive issues with respect to their successful applications. In this work, an atmospheric pressure plasma jet (APPJ) is generated in Ar + 1% CH4 gas flow by a bipolar nanosecond high-voltage (HV) source with a maximum pulse repetition rate up to 1 MHz (i.e. minimum pulse interval ΔT = 1 μs) in burst mode. The absolute density of hydrogen atom at ground state is measured by the two-photon absorption laser-induced fluorescence method. It is observed that with ΔT = 1 μs, the H atom density keeps increasing during the first eight HV pulses and later on, the H atom density is maintained at a quasi-stable value while more HV pulses are applied. When decreasing ΔT from 10 to 1 μs, while keeping the total number of HV pulses the same (with similar coupled energy), the peak H atom density increases by a factor of more than four times, but the decay of H atom density after the pulse burst with ΔT = 1 μs is faster. Another effect of short ΔT is to extend the axial distribution of the H atom outside the APPJ’s nozzle, and the ΔT = 2 μs case has the highest averaged H atom density when taking its temporal evolution and axial distribution into consideration. In this work, we propose that the intensive nanosecond HV burst is an efficient approach to enhance the active species density in non-thermal plasmas when a rapid response is required.

Constraining modified gravity with quantum optomechanics
Authors: Qvarfort Sofia , Rätzel Dennis , Stopyra Stephen
Published: November 2021

We derive the best possible bounds that can be placed on Yukawa- and chameleon-like modifications to the Newtonian gravitational potential with a cavity optomechanical quantum sensor. By modelling the effects on an oscillating source-sphere on the optomechanical system from first-principles, we derive the fundamental sensitivity with which these modifications can be detected in the absence of environmental noise. In particular, we take into account the large size of the optomechanical probe compared with the range of the fifth forces that we wish to probe and quantify the resulting screening effect when both the source and probe are spherical. Our results show that optomechanical systems in high vacuum could, in principle, further constrain the parameters of chameleon-like modifications to Newtonian gravity.

Published: November 2021

Based on the data release of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope survey (LAMOST DR5) and the Gaia Early Data Release 3 (Gaia EDR3), we construct a sample containing 46,109 giant (log g ≤ 3.5 dex) stars with heliocentric distance d ≤ 4 kpc, and the sample is further divided into two groups of the inner (R
GC < 8.34 kpc) and outer region (R
GC > 8.34 kpc). The L
Z distributions of our program stars in the panels with different [Fe/H] and [α/Fe] suggest that the thick-disk consists of two distinct components with different chemical compositions and kinematic properties. For the inner region, the metal-weak thick disk (MWTD) significantly contributes when [α/Fe] > +0.2 dex and [Fe/H] < −0.8 dex, while the canonical thick-disk (TD) dominates when [Fe/H] > −0.8 dex. However, MWTD clearly appears only when [α/Fe] > +0.2 dex and [Fe/H] < −1.2 dex for the outer region, and its proportion is lower than that of the inner region within the same metallicity. Similar results can be obtained from the V

ϕ
distribution. The higher fraction of MWTD in the inner region than that in the outer region implies that MWTD may form in the inner disk, and is observational evidence about the inside-out disk formation scenario.

The potassium solubilizing biofertilizer based on selected potassium solubilizing bacteria (KSB) can facilitate availability of potassium in primary silicate minerals containing potassium to be absorbed by the plants. The key to successful application of biofertilizer in showing positive effects on inoculated plants is the selection of a carrier material that can guarantee viability of inoculants during shelf life before being applied in the field. The purpose of this study was to determine viability of three selected KSB isolates which were formulated in a mixture of K-feldspar (KF), rice straw compost (RSC), rice husk biochar (RHB), and Aleksandrov liquid medium (ALM) as a carrier material for 24 weeksof shelf life. The experiment used a completely randomized design with nine treatments of carrier material composition and three replications. The results showed formula of potassium solubilizingbiofertilizer with a composition of 1% mixed culture KSB + 15% KF + 30% RSC + 45% RHB+9% ALM was the best formula with high inoculant viability during 4 weeks of shelf life. It wasevidenced by the increase in respiration and total KSB population by 17.2% and 213.2%, respectively, compared to formula that produced the lowest respiration and total KSB population.

Authors: Siagian Novriadi Antonius , Wage Sutarman , Sawaluddin
Published: November 2021

The Naïve Bayes method is proven to have a high speed when applied to large datasets, but the Naïve Bayes method has weaknesses when selecting attributes because Naïve Bayes is a statistical classification method that is only based on the Bayes theorem so that it can only be used to predict the probability of the class membership of a class independently. Independent without being able to do the selection of attributes that have a high correlation and correlation between one attribute with other attributes so that it can affect the value of accuracy. Naïve Bayesian Weight has been able to provide better accuracy than conventional Naïve Bayesian. Where an increase in the highest accuracy value obtained from the Water Quality dataset is equal to 88.57% in the Weight Naïve Bayesian classification model, while the lowest accuracy value is obtained from the Haberman dataset which is 78.95% in the conventional Naïve Bayesian classification model. The increase in accuracy of the Weight Naïve Bayesian classification model in the Water Quality dataset is 2.9%. While the increase in accuracy value in the Haberman dataset is 1.8%. If done the average accuracy of each dataset using the Weight Naïve Bayesian classification model is 2.35%. Based on the testing that has been done on all test data, it can be said that the Weight Naïve Bayesian classification model can provide better accuracy values than those produced by the conventional Naïve Bayesian classification model.

Framing the transition towards sustainable agri-food supply chains
Authors: Tsoulfas G T , Mouzakitis Y
Published: November 2021

The connection of the agri-food sector with the agenda of sustainable development comes naturally, as the chain from production to processing, trading, distribution and consumption is directly connected with significant issues in environmental, economic, and social realms. Today’s challenge for businesses is not whether to embrace sustainability, but rather how to effectively establish sustainable supply chains. Therefore, a solid grasp of the move from “conventional” to “sustainable” supply chains is necessary. In this paper, we focus on the supply chain management of the agri-food sector, seeking to shed light on practices which may contribute to the transition of the sector towards sustainability. In this vein, we extend the conceptual framework which was proposed by Beske and Seuring (2014) so that it accommodates the contemporary particularities of agri-food supply chains.
Investigation of the envelope’s thermal transmittance influence on the energy efficiency of residential buildings under various Mediterranean region climates
Authors: Karanafti A C , Theodosiou T G
Published: November 2021

Improving the energy efficiency of residential buildings is of outmost importance for reducing their environmental footprint. Recent studies demonstrate that a highly insulated building envelope may burden the building’s performance during the cooling period, especially in regions with hot summers. In this study, the energy performance of a residential building in different Mediterranean regions (Jordan, Greece, Iraq, Egypt, Syria, Morocco, Cyprus, Saudi Arabia, Libya, and Spain) is investigated. Two thermal transmittance values are applied to the building shell, a scenario with a very low one and a scenario with a higher one, to examine under which conditions the cooling performance is improved. A dynamic insulation configuration is also implemented, and its operation is studied for the cooling period of each city. It is concluded that in Southern European and Northern African regions building envelopes with lower thermal resistances perform better, while in even Southern regions an increased thermal resistance may prevent the heat from entering the building more effectively. With the switching insulation system, a great reduction in the cooling demands was reported, which reached up to 50% in Spain, and it was shown that in the southern regions the configuration’s operation should be customized to the ambient conditions to optimize its performance.
Climate change and built environment - the role of urban greenery as a mitigation strategy in Greek urban areas
Authors: Apostolopoulou D , Tsoka S
Published: November 2021

Extreme thermal conditions and heat waves, as a result of global warming, have increased in recent years. Especially in the Mediterranean area, cities face higher temperatures during summer months which severely affect thermal comfort and citizens’ well-being. In this context, this study aims to evaluate the role of urban greenery as a mitigation strategy and focuses on its effect towards the improvement of the urban microclimate and thermal comfort under extreme summer conditions. To this aim, a typical square, located in Athens, Greece, has been chosen as a case study. The microclimatic conditions are evaluated for its present state and after an increase of 20% of soil surface and 30% of trees, while both current (i.e., 2020) and future summer climatic conditions (for the year 2060) are examined. It was also proposed that all the soil surfaces would be covered in grass. The potential air temperature, mean radiant temperature and surface temperature are analysed by simulation means, using the ENVI-met microclimate simulation tool. The results of this study showed that increasing the vegetation ratio inside the study area contributes to considerably lower surface temperatures, while a significant reduction on mean radiant and air temperature at the pedestrian level is also achieved, forming better microclimate conditions. Urban greenery is an important factor for healthy and resilient cities. Its presence can provide lower temperatures in the pedestrian level during summer months, reforming the microclimate. The outcomes of this study can be used by urban planners and stakeholders to improve environmentally urban areas, mitigate the results of climate change, and create resilient cities.

Published: November 2021

Field testing is often a very reliable way to determine the mechanical properties of soil materials and in some cases the most appropriate and unique way to obtain accurate measurements. Geotechnical engineers and engineering geologists perform geotechnical investigations to obtain information on the physical and mechanical properties of soil and rock underlying (and sometimes adjacent to) a site to design earthworks and foundations for proposed structures. The object of the present work is the recording of the geotechnical data of the center and districts of the city of Larissa, the knowledge of which is necessary for the construction and erection of construction works, as well as the characteristics and points that need special attention in each area. Finally important conclusions refer to the construction culture, that project authorities and contractors should draw on, accordingly.

Published: November 2021

This work describes the preparatory steps for the planning of a light pollution protected area in the form of an International Dark-Sky Park in Aenos National Park at the island of Kefalonia that refer to lighting and light pollution. In more detail, we identified and measured luminance, illuminance and spectrum of public lighting at the island of Kefalonia in areas that are adjacent to the National Park and may influence its operation as a Dark Sky Park. This procedure also includes identifying the luminaire types and light sources, judging their suitability, identifying malpractices and proposing changes. In general, many malpractices were identified both in old lighting installations as well as recent LED retrofits or new installations with more common ones being rich sources in blue light and use of non-cut off luminaires. Light pollution measurements were performed that prove that Aenos National Park has dark enough skies to meet requirements.

Published: November 2021

Smoking epidemics have increased the number of smokers around the globe. Moreover, the world urbanization steadily increases. As a result, environmental problems are exacerbated by the proliferation of combustible and electronic cigarettes and the cement invasion of permeable spaces. Therefore, sustainable construction/building materials that use recycled ingredients like cigarette filters are worth considering. This paper assesses and compares, for the first time in the literature, the chemical and mechanical properties of geopolymer concrete substituted by 0, 10, 15, and 20% by weight of cigarette filters. Results have shown that the higher the amount of cigarette filters, the lower the mechanical strength. However, the results also indicate that the geopolymerization reaction is still in progress as the compressive strength of all aged samples is still increasing.
Green and blue infrastructure as a tool to support decision-making in the spatial planning process. The case of Lake Trichonida, Greece
Authors: Tasopoulou A , Pozoukidou G
Published: November 2021

Green infrastructure (GI) has gained high interest over the last two decades, as a policy tool to promote sustainable development and enhance the resilience of both the urban and rural environments. GI has the potential to offer multiple benefits through the services and functions performed within ecosystems, and thus its implementation requires an integrated and balanced approach that emphasizes the multifunctional nature of a territory. Multifunctionality along with connectivity and networking appear to be core features accepted by all disciplines using the term. GI incorporates green spaces, or/and blue if aquatic ecosystems are concerned, and other physical features in terrestrial and marine areas. This paper presents the development and application of a methodology to facilitate spatial planning choices, incorporating a green and blue infrastructure (GBI) approach, in a Greek case, the wider area of Lake Trichonida in Western Greece. The conceptual basis of the proposed approach embeds both natural and man-made features that could function as green or blue infrastructure. The methodology and its application facilitated the identification of planning priorities and the pursue of planning objectives, thus supporting the decision-making in the spatial planning process.

Remediation of oil-drilling cuttings by ozonation in semibatch bubble column reactors
Authors: Christodoulis K F , Theodoropoulou M A , Tsakiroglou C D
Published: November 2021

The remediation of oil-drilling cuttings (ODC), containing a high percentage of total organic carbon (TOC), total petroleum hydrocarbons (TPH) and moisture, is a challenge. Ozonation is an advanced oxidation method able to destruct a broad variety of organic substances from water and soil. Oil-drilling cuttings are pre-treated inside a sonication bath with three solutions of artificial seawater containing 0.0, 0.2, and 0.5% w/w sodium dodecyl sulphate (SDS) which acts as surfactant and favours the solubilisation of hydrocarbons from the solid to the liquid phase. Afterwards, each pre-treated ODC is diluted at a ratio 1:5 with the corresponding type of seawater, and ozonation of the suspension occurs in a bubble column reactor made of poly methyl methacrylate (PMMA). The transient changes of the TOC content in ODC during the various stages of its treatment are measured with the Walkley-Black titration method. It seems that a percentage ~12-25% of TOC dissolves and is transferred from ODC to seawater, while the treatment of ODC suspended in seawater with ozone leads to the complete removal of the TOC after 2 hrs.

One of the breeding methods suitable for low N evaluation is the diallel method between inbred parents (homozygous lines) that are tolerant of low N stress. The aim of this study was to assess the genotype tolerance to low N with comparable yields. The research consisted of two stages. The first stage is the development of hybrid maize grains (F1) using the half diallel cross method. This activity was carried out in KP. Maros, Research Center for Cereal Crops. A half-diallel cross refers to the Griffing IV method, by involving 11 low N-tolerant genotypes (AVLN 100-1, AVLN 118-2, AVLN 122-2, AVLN 124-4, AVLN 32-3, AVLN 83-1, AVLN 83-4, AVLN 83-6, AVLN 86-2, MAL 04, and AVLN 124-9). The second stage was carried out in KP. Bajeng to evaluate 52 genotypes of hybrid maize from diallel crosses plus four hybrid varieties Advanta 777, Bisi 18, P 27 and JH 37 for control. The experiment was carried out under conditions of low N stress (100 kg N/ha) and normal N (200 kg N/ha). The experiment used a randomized block design with three replications. Hybrids that are tolerant (T) under conditions of low N stress was best indicated by AVLN 83-4/AVLN 124-4 genotype pair, with significant higher grain yield than Bisi-18 and JH 37 varieties. This hybrid produced average grain yield of 7.87 t/ha under both conditions. Inbred maize genotypes classified as medium tolerant (MT) were AVLN 83-4/AVLN 124-9, AVLN 124-4/AVLN 86-2, AVLN 122-2/AVLN 124-4, AVLN 83-1/AVLN 124-9, has similar yield potential as to the control varieties.

Root growth and development is one of the morphological characters which related to drought tolerant traits. This study aims to evaluate the root distribution pattern of 30 rice genotypes to support the breeding of drought tolerant varieties. The research was conducted in ICRR greenhouse in Sukamandi, Subang, Indonesia from October to December 2015. Thirty rice genotypes, consisting of cultivars, promising lines (prior to be released as new varieties), and check varieties, were arranged using randomized complete block design with three replications. Seed were planted in mini pots containing a mixture of sand and soil media with a concave sieve at the top. The filter is divided into three zones, namely upper (1), middle (2), and lower (3). The pot was placed in a plastic box filled with water to maintain the humidity. The results showed that Mekongga had the number of tillers, the number of fresh leaves, the number of roots in zone 1, and the total number of roots significantly higher than the best check variety, Salumpikit. In this study, it was found that the amount of metaxylem between genotypes was different. Salumpikit has the most metaxylem among other genotypes. Further research is expected to be carried out both in drought and optimum condition as a control to see the correlation between root architecture with drought tolerance in the field.

New rice varieties could be released by various plant breeding methods including mutation induction using gamma rays irradiation. Radiosensitivity and LD50 values (Lethal Dose, 50%) can be determined from the morphological response of plants to irradiation treatment in M1generation. The research aims to determine the value of LD50and the performance of rice mutant traits of Mira-1 and Bestari. The experiment was conducted using the Randomized Complete Block Design (RCBD) with two factors (rice varieties and gamma irradiation doses) and three replications. The plant traits observed were the percentage of germination, seedling height, and root length in the seedling phase. The results showed that LD50values in the Mira-1 and Bestari varieties differed in all observed characters. The optimum dose to induce rice mutation of the varieties under investigation is within the range of 521.40 – 663.68 Gy.

Development of tolerant variety can be conducted in the targeted area. It will increase efficiency in producing the acid-tolerant lines. However, the availability of diversity is key in selection. Multiple crosses or crosses between F1 hybrids can be one approach in creating high population diversity. Therefore, the development and selection of offspring of the selfing 1 generation from a cross of two hybrids can be a solution in producing tolerant lines. This study aimed to select multiple-cross maize lines in the generation S1 in an acidic environment. The research was carried out from August to November 2019 at the Maros Cereal Research Center, South Sulawesi. This study was designed with an Augmented Design as an experimental design and a randomized block design as an environmental design. The lines used consisted of 100 S1 lines from crosses of NK7328/HJ28 that did not repeat and six comparison varieties, namely NK7328, HJ28, Sukmaraga, Srikandi Kuning, Bima-9, and Piooner 36 repeated in each block. Based on the results of this study, the evaluation of maize S1 lines under acid soil showed a good variability, especially on generative traits. The ear weight is the best secondary character supported the Grain weight per Ear as the main character. The result of selection showed that 20 S1 lines recommended to selfing cross for continued on the next generation.

Assessment nutrient content of maize leaf is particularly important in achieving higher grain yield. Characterization of leaf chlorophyll involves routine Soil Plant Analyzer Development (SPAD) reading particularly at critical stage of growth development. The objective of the study was to assess the color spectrum of maize leaf in relation to the chlorophyll content by using Random-forest modeling. genotypes of corn plants based on the characters of the ear and kernel using a logistic regression model. The research was conducted at IP2TP Bajeng in 2021 by planting maize varieties at various fertilizer level. RGB data of maize leaf was recorded by using Hamamatsu sensor (Hamamatsu, Japan), and converted to HIS, HSV and LAB color spectrum. The results indicated that Random-forest model with 20-fold validation indicated the highest accuracy as compared to the other fold-range. Among the tested model, integration of Random-forest model to LAB (Light, red/green coordinate, and the yellow/blue coordinate) color spectrum provided the best model performances with RMSE (4.77), MSE (22.76), MAE (3.80) and R2 (0.853). This value indicates that the use of Hamamatsu color sensor and converted into LAB color spectrum provided the best SPAD (Soil Plant Analyzer Development) reading with high accuracy and consistency of results. Thus, digital based model can be integrated with manual selection for fast and precise nutrient monitoring.
