Environmental Performance of Alternative Green Polyol Synthesis Routes: A Proposal for Improvement

This study verified the environmental effectiveness of potentially less aggressive routes for the synthesis of poly(propylene/ethylene oxide) glycol (PPG). The analysis was developed in two stages. Firstly, the environmental performance of the conventional PPG processing route was compared to alternative variants—vegetal PPG and CO2-based PPG—applying the life cycle assessment technique to measure the primary energy demand, global warming potential, acidification, photochemical oxidation, and freshwater ecotoxicity impact categories. The synthesis of vegetable polyols from bio-based assets, such as vegetable oils, and the application of CO2 conversion routes as an alternative to technologies supported by petroleum and natural gas were studied. The use of CO2 recovered through carbon capture and usage practices resulted in environmental gains for PPG production. The processing routes within vegetal assets were not an environmentally attractive option as the performance was worse than the conventional arrangement by 144% for the global warming impact category, an increase related to the deforestation carried out to expand soybean cultivation in Brazil. Secondly, improvement scenarios to mitigate the environmental impacts of alternative routes were performed. The hypothesis of using cleaner inputs to obtain a more ecofriendly route was tested. The analysis concluded that the use of high-purity CO2 brings fewer benefits compared to other capturing sources that need a purification process before feeding the PPG synthesis.
SOIL-STRUCTURE INTERACTION EFFECT ON EARTHQUAKE VULNERABILITY ASSESSMENT OF MOMENT RESISTING FRAMES: THE ROLE OF THE STRUCTURE

This paper investigates the influence of soil-structure interaction (SSI) on the seismic fragility of moment resisting reinforced concrete (RC) frames. For this purpose, a set of typical RC moment resisting frames (MRF) is used as a benchmark, namely (i) a two-story, (ii) a four-story and (iii) a nine-story RC MRF, designed within the framework of the first Greek Seismic Code and modeled using fiber elements. The subsoil conditions are selected indicatively, matching typical soft clay soil conditions encountered in engineering practice. The soilfoundation-structure system is modeled using three different configurations for the foundation; (i) fixed-base, (ii) Beam-on-Nonlinear -Winkler-Foundation (BNWF) spring-type elements, and (iii) lumped individual elastic springs. The models are thereafter subjected to eleven ground motion records, derived from eleven independent seismic events, scaled in terms of the Incremental Dynamic Analyses (IDA) performed, leading to a total of 2640 individual analyses. The corresponding fragility curves are thereafter derived, estimated as a function of rock outcropping peak ground acceleration for four limit states. The differentiation between the derived fragility curves is subsequently discussed, highlighting the influence of SSI and nonlinear soil behavior on the earthquake vulnerability of RC MRF. The results are comparatively presented for the three MRF models examined, indicating how SSI affects each case. Pre-processing, post-processing and the numerical analyses are performed using open source tools, namely OpenSees and Python programing language scientific tools.
14 9 v 2 2 1 M ar 2 00 1 The metric and strong coupling limit of the M 5-brane G

We find the analogue of the Boillat metric of Born-Infeld theory for the M5-brane. We show that it provides the propagation cone of all 5-brane degrees. In an arbitrary background field, this cone never lies outside the Einstein cone. An energy momentum tensor for the three-form is defined and shown to satisfy the Dominant Energy Condition. The theory is shown to be well defined for all values of the magnetic field but there is a limiting electric field strength. We consider the strong coupling limit of the M5-brane and show that the corresponding theory is conformally invariant and admits infinitely many conservation laws. On reduction to the Born-Infeld case this agrees with the work of Bia lnicki-Birula.
Differentiation-induced Colocalization of the Kh-type Splicing Regulatory Protein with Ptb and the C-src Pre-mrna

We have examined the subcellular localization of the KH-type Splicing Regulatory Protein (KSRP). KSRP is a multidomain RNA-binding protein implicated in a variety of cellular processes including splicing in the nucleus and mRNA localization in the cytoplasm. We find that KSRP is primarily nuclear with a localization pattern that most closely resembles that of Polypyrimidine Tract Binding Protein (PTB). Colocalization experiments of KSRP with PTB in a mouse neuroblastoma cell line determined that both proteins are present in the perinucleolar compartment (PNC), as well as in other nuclear enrichments. In contrast, HeLa cells do not show prominent KSRP staining in the PNC, even though PTB labeling identified the PNC in these cells. Since both PTB and KSRP interact with the c-src transcript to affect N1 exon splicing, we examined the localization of the c-src pre-mRNA by fluorescence in situ hybridization (FISH). The src transcript is present in specific foci within the nucleus that are presumably sites of src transcription, but are not generally perinucleolar. In normally cultured neuroblastoma cells, these src RNA foci contain PTB, but little KSRP. However, upon induced neuronal differentiation of these cells, KSRP appears in the same foci with src RNA. PTB localization remains unaffected. This differentiation-induced localization of KSRP with src RNA correlates with an increase in src exon N1 inclusion. These results indicate that PTB and KSRP do indeed interact with the c-src transcript in vivo, and that these associations change with the differentiated state of the cell.
DAMPING CALCULATION FROM FREE- AND FORCED-VIBRATION FIELD EXPERIMENTS AT THE LARGE-SCALE STRUCTURE OF EUROPROTEAS

Analytical solutions for the evaluation of system damping are validated through freeand forced-vibration experiments performed in the large-scale prototype structure of EuroProteas located in the experimental facility of Euroseistest in Northern Greece. EuroProteas is a simple stiff model structure founded on soft soil and is especially designed to mobilize strong soil-structure interaction (SSI) effects. Its outer dimensions are 3x3x5m and its structural mass and stiffness are reconfigurable, allowing four different model configurations and covering a wide range of resonant frequencies. We describe analytical methods proposed in literature and guidelines for calculating system damping. We apply these methods to the experimental data obtained from a wide range of freeand forcedvibration tests in order to validate them and calculate the damping ratio of the system. The results indicate strong influences from both hysteresis in foundation-soil interaction and radiation damping. For large forces the presence of soil nonlinearities is identified.
Self-Beliefs of Success for College Calculus Students

Calculus is often viewed as one of the gateway courses for STEM majors. It is important for STEM educators to understand not only what demographic and prior academic factors contribute to the success of students taking this course, but also the students’ perception of their own academic capabilities. In this paper we will present findings from a survey of over 200 Calculus I students at a large research-intensive university. The survey included questions on academic self-efficacy, academic engagement, learning climate, class enjoyment, anxiety, and other emotional factors. In analyzing the survey results, significant differences were found among students enrolled in different colleges at the university. Specifically, students who studied at the College of Technology, the College of Natural Science and Math, College of Engineering, or other colleges demonstrated significantly different expectations on their success in Calculus. The survey results also indicated an interaction effect of students’ grade level of the association between the colleges they are in and their expectation of their final score in the course.
Identification of Informative Tweet during Disasters

- During the time of crisis, people often post countless instructive and informative tweets on various social media platforms such as Twitter. Recognizing informative tweets is a difficult errand during the fiasco from such a vast pool of tweets. These tweets can be textual as well as photographic in nature. As an answer to this issue of sorting out enlightening tweets, we present a way to perceive the distinguishing calamity related informative tweets from the Twitter streams utilizing the textual content and the images together. Our objective is to construct a model by combining Bi-directional Long Short-Term Memory (Bi-LSTM) and Convolutional Neural Network (CNN) to categorize the textual content for the tweets. The primarily image-based classification model will utilize the adjusted VGG-16 design to extricate the features from the picture and will classify the image accordingly. The output of the text-based model and the image-based model will be consolidated using the late fusion technique to predict the tweet label.

This paper proposes a high gain, and a new shape of an Ultra-wideband (UWB) Mercedes-Shaped printed monopole (MPM) antenna feds by a coplanar waveguide (CPW) designed to use for UWB applications. The Mercedes patch shaped consists of a circular ring embedded with threelegged leads to enhance the antenna bandwidth. The antenna has an electrical dimension of 1. 2λo× 1. 2λo× 0. 039λo at the centre operating frequency of 7.35 GHz. The MPM antenna provides a bandwidth of 10.5GHz covering the licensed UWB frequencies, starting from 2.1 GHz to12. 6 GHz. The MPM antenna exhibited a max gain of 6.88 dB at 8.6 GHz with a significant radiation efficiency of 97.4%. The coverage bandwidth of the proposed MPM antenna is wide enough to be used for UWB and radar applications. Streszczemnie.

A Web Guide to Perceptually Congruent Sonification

Sonification is an increasingly popular mechanism for data exploration, promoting the need for a greater understanding of human auditory perception and of how sonified information is designed, presented, and interpreted. In this paper, perceptual modelling is used to explore and demonstrate how perceptual phenomena are accounted for in sonification design. The framework, extracted from a larger body of work, links perceptual phenomena such as stream segregation to sonification mappings to provide a systematic approach to identifying and addressing perceptually-driven problems in applied sonification. A web guide functions to situate and guide designers through the complex theoretical constituents of auditory perception incorporated in the Perceptually Congruent Sonification (PerCS) framework. This web guide (hosted on sonification.ie) highlights and summarises the perceptual phenomena most relevant to sonification design and uses simple audio-visual interactions to demonstrate their effect. Preliminary qualitative feedback from a brief survey elucidates a small number of end-user concerns and comments.
Large Electronic Anisotropy and Enhanced Chemical Activity of Highly Rippled Phosphorene

We investigate the electronic structure and chemical activity of rippled phosphorene induced by large compressive strains via first-principles calculation. It is found that phosphorene is extraordinarily bendable, enabling the accommodation of ripples with large curvatures. Such highly rippled phosphorene shows a strong anisotropy in electronic properties. For ripples along the armchair direction, the band gap changes from 0.84 to 0.51 eV for the compressive strain up to −20% and further compression shows no significant effect; for ripples along the zigzag direction, semiconductor-to-metal transition occurs. Within the rippled phosphorene, the local electronic properties, such as the modulated band gap and the alignments of frontier orbitals, are found to be highly spatially dependent, which may be used for modulating the injection and confinement of carriers for optical and photovoltaic applications. The examination of the interaction of a physisorbed NO molecule with the rippled phosphorene under differ.
On the energy of quasiconformal mappings and pseudoholomorphic curves in complex projective spaces

We prove that the energy density of uniformly continuous, quasiconformal mappings, omitting two points in CP, is equal to zero. We also prove the sharpness of this result, constructing a family of uniformly continuous, quasiconformal mappings, whose areas grow asymptotically quadratically. Finally, we prove that the energy density of pseudoholomorphic Brody curves, omitting three “complex lines” in general position in CP, is equal to zero. According to the Picard Theorem, a holomorphic function f defined on the complex plane C is constant as soon as f(C) omits at least three values in CP1. This result has different generalizations in at least two directions. S.Rickman [11] proved that for every n ≥ 2 and for every K > 1, a nonconstant entire Kquasiregular mapping in Rn omits at most m = m(n,K) values. M.Green [6] proved that a holomorphic map from C to the complex projective space CPn, omitting (2n+ 1) hyperplanes in general position, is constant. An almost complex version of that result was proved by J.Duval [5] for entire pseudoholomorphic curves in the complement of five J-lines, in general position in CP2 endowed with an almost complex structure J tamed by the Fubini Study metric ωFS . Let f be a mapping defined on C with values in CPn, f ∈ W 1,2 loc (C). We recall that if D ⊂⊂ C, then Area(f(D)) := ∫ D f ωFS is the area of f(D), counted with multiplicity. Then, the energy density E(f) defined by E(f) = lim sup R→∞ 1 πR2 Area(f(DR)) = lim sup R→∞ 1 πR2 ∫
High Accuracy Gene Signature for Chemosensitivity Prediction in Breast Cancer

Neoadjuvant chemotherapy for breast cancer patients with large tumor size is a necessary treatment. After this treatment patients who achieve a pathologic Complete Response (pCR) usually have a favorable prognosis than those without. Therefore, pCR is now considered as the best prognosticator for patients with neoadjuvant chemotherapy. However, not all patients can benefit from this treatment. As a result, we need to find a way to predict what kind of patients can induce pCR. Various gene signatures of chemosensitivity in breast cancer have been identified, from which such predictors can be built. Nevertheless, many of them have their prediction accuracy around 80%. As such, identifying gene signatures that could be employed to build high accuracy predictors is a prerequisite for their clinical tests and applications. Furthermore, to elucidate the importance of each individual gene in a signature is another pressing need before such signature could be tested in clinical settings. In this study, Genetic Algorithm (GA) and Sparse Logistic Regression (SLR) along with t-test were employed to identify one signature. It had 28 probe sets selected by GA from the top 65 probe sets that were highly overexpressed between pCR and Residual Disease (RD) and was used to build an SLR predictor of pCR (SLR-28). This predictor tested on a training set (n = 81) and validation set (n = 52) had very precise predictions measured by accuracy, specificity, sensitivity, positive predictive value, and negative predictive value with their corresponding P value all zero. Furthermore, this predictor discovered 12 important genes in the 28 probe set signature. Our findings also demonstrated that the most discriminative genes measured by SLR as a group selected by GA were not necessarily those with the smallest P values by t-test as individual genes, highlighting the ability of GA to capture the interacting genes in pCR prediction as multivariate techniques. Our gene signature produced superior performance over a signature found in one previous study with prediction accuracy 92% vs 76%, demonstrating the potential of GA and SLR in identifying robust gene signatures in chemo response prediction in breast cancer.
Chemoselective Reduction of Halo-Nitro Aromatic Compounds by β-Cyclodextrin-Modified Transition Metal Catalysts in a Biphasic System

Transition metal complexes of a water-soluble b-cyclodextrin modified diphosphine can be used in the biphasic (H2O/organic) hydrogenation of halo-nitro aromatic compounds. The platinum complex is the most active and selective, resulting in the chemoselective formation of halo-aniline derivatives.
AMBIENT NOISE VIBRATIONS AS A TOOL FOR SEISMIC RESPONSE ASSESSMENT OF SELECTED MONUMENTAL STRUCTURES OF CRETE

The contribution of local site conditions to the observed unequal spatial damage distribution, particularly for historical and monumental structures has been revealed by destructive worldwide earthquakes as well as by recent advances in soil-structure interaction studies. The importance of strengthening resilience of cultural heritage against natural disasters has been articulated in the Sendai Framework, while the proactive disaster risk management has been annotated by the global agenda 2030. This study is particularly focused on important historical and monumental structures and religious cultural heritage masonry structures (such as minarets, church bell towers) in the cities of Chania, Rethymno and Heraklion of Crete. The Horizontal to Vertical Spectral ratio (HVSR) technique applied to ambient noise recordings is used to assess the frequencies of vibration of historical and monumental structures of Crete and to examine potential soil structure interaction phenomena. The geological setting of the studied historical and monumental structures is mainly characterized by Quaternary and Neogene deposits locally very loose deposits and by the presence of large scale fault zones. Considering the geotectonic setting, the surface geology and the numerous historical and monumental structures of Crete, the determination of prone resonating buildings and the development of integrated tools for situational awareness towards to a proactive earthquake risk management are important issues with the purpose to support civil protection preparation and local operational decision making authorities of Crete in terms of earthquake disaster.
Abiotic stresses induced physiological, biochemical, and molecular changes in Betula platyphylla: a review

Abiotic stress is one of the major factors in reducing plant growth, development, and yield production by interfering with various physiological, biochemical, and molecular functions. In particular, abiotic stress such as salt, low temperature, heat, drought, UV-radiation, elevated CO2, ozone, and heavy metals stress is the most frequent study in Betula platyphylla Sukaczev. Betula platyphylla is one of the most valuable tree species in East Asia facing abiotic stress during its life cycle. Using transgenic plants is a powerful tool to increase the B. platyphylla abiotic stress tolerance. Generally, abiotic stress reduces leaves water content, plant height, fresh and dry weight, and enhances shed leaves as well. In the physiological aspect, salt, heavy metal, and osmotic stress disturbs seed germination, stomatal conductance, chlorophyll content, and photosynthesis. In the biochemical aspect, salt, drought, cold, heat, osmotic, UV-B radiation, and heavy metal stress increases the ROS production of B. platyphylla cells, resulting in the enhancement of enzymatic antioxidant (SOD and POD) and non-enzymatic antioxidant (proline and AsA) to reduce the ROS accumulation. Meanwhile, B. platyphylla upregulates various genes, as well as proteins to participate in abiotic stress tolerance. Based on recent studies, several transcription factors contribute to increasing abiotic stress tolerance in B. platyphylla, including BplMYB46, BpMYB102, BpERF13, BpERF2, BpHOX2, BpHMG6, BpHSP9, BpUVR8, BpBZR1, BplERD15, and BpNACs. These transcription factors bind to different cis-acting elements to upregulate abiotic stress-related genes, resulting in the enhancement of salt, drought, cold, heat, osmotic, UV-B radiation, and heavy metal tolerance. These genes along with phytohormones mitigate the abiotic stress. This review also highlights the candidate genes from another Betulacea family member that might be contributing to increasing B. platyphylla abiotic stress tolerance.
Evaluation of total antioxidant and free radical scavenging activities of Callistemon citrinus (Curtis) Skeels extracts by biochemical and electron paramagnetic resonance analyses

Plants are known to contain a variety of compounds exhibiting antioxidant and free radical scavenging activities. The present study focuses on the preparation of crude extracts from Callistemon citrinus (CC) plant leaf using different solvents (such as ethanol, methanol and n-hexane), to assess their antioxidant and free radical scavenging ability. The extracts of ethanol (EE), methanol (ME) and n-hexane (HE) were used separately to measure their individual free radical quenching efficiency against 1,1-diphenyl-2-picrylhydrazyl (DPPH), ABTS˙+, superoxide (O2˙−), hydroxyl (HO˙), nitric oxide (NO˙) and hydrogen peroxide (H2O2). The reducing power as well as the phenolic and flavonoid contents of the extract was also assayed. Concentration and time dependent HO˙ radical scavenging potentials of these extracts were monitored by Electron Paramagnetic Resonance (EPR) spectroscopy. The results of all these studies suggested that the EE had highest free radical scavenging property followed by ME and HE. This activity increased with increase in extract concentration in situ. The observed potential antioxidant and free radical scavenging activities of the EE of CC leaves could be used for therapeutic purpose in the treatment of oxidative stress induced disorders.
GSMMC-2021 Project-Plant Hydraulics

Plant Hydraulics is an important part of understanding climate dynamics because it describes plants’ important key role as a link between the land and the atmosphere. In an Earth System Model (ESM), i.e., a model that is able to capture the complex dynamics of the Earth via the complex interactions between all its components (ocean, atmosphere, land and ice masses, etc), plants constitute what is referred to as the land biosphere. We seek to form a simple model that can be expanded upon and integrated into an ESM. This model looks at how plants, more specifically trees, absorb water through roots from the ground and use capillary effects to move water to their leaves where they can control water loss through controlling their stomata (tiny pores on leaves) aperture/closure mechanism. Transpiration is the loss of water from a plant in the form of water vapor. Water is absorbed by roots from the soil and transported as a liquid state to the leaves via the xylem, that is the plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant. In the leaves, small pores (stomata) allow water to escape as a vapor state, depending on the plant’s surrounding environment and available resources (stomatal openings try to maximize the difference between carbon gain and water loss penalty, depending on also the atmosphere radiation, temperature and humidity level). In actively growing plants, water continuously
