Regionalne strategie innowacji jako czynnik aktywizacji polskiej przestrzeni przemysłowej
Authors: Wieloński Andrzej , Szmigiel Katarzyna
Published: March 2021

The main goal of the article is to present the regional innovation strategies in the context of the industrial changes in Poland. The analysis has three parts. The first part introduces the general aims of RIS and their history in Europe, the second concerns the RIS in Poland and one of the Polish RIS in particular – RIS Silesia, and the third part describes the effects of Regional Innovations Strategies.RIS are the instruments of regional governments to build the regional innovation systems. A regional innovation system is the environment improving the entrepreneurship and innovation. RIS have been known in Europe since the 1980s but in Poland they are a new instrument implemented by the relatively new structures of regional government.The process of creation and implementation of these documents should be observed by the academics from the beginning, as it may turn out to be one of the most important instruments of the economic policy of the Polish regions. This is because of the financial capacity of the Polish regions and their willingness to follow the West European regions’ example.
Entanglement-assisted quantum codes achieving the quantum singleton bound but violating the quantum hamming bound
Authors: Li Ruihu , Guo Luobin , Xu Zongben
Published: March 2021

We give an infinite family of degenerate entanglement-assisted quantum error-correcting codes (EAQECCs) which violate the EA-quantum Hamming bound for non-degenerate EAQECCs and achieve the EA-quantum Singleton bound, thereby proving that the EA-quantum Hamming bound does not asymptotically hold for degenerate EAQECCs. Unlike the previously known quantum error-correcting codes that violate the quantum Hamming bound by exploiting maximally entangled pairs of qubits, our codes do not require local unitary operations on the entangled auxiliary qubits during encoding. The degenerate EAQECCs we present are constructed from classical error-correcting codes with poor minimum distances, which implies that, unlike the majority of known EAQECCs with large minimum distances, our EAQECCs take more advantage of degeneracy and rely less on the error correction capabilities of classical codes.
Performance and error analysis of Knill's postselection scheme in a two-dimensional architecture
Authors: Lai Ching-Yi , Paz Gerardo , Suchara Martin , Brun Todd A.
Published: March 2021

Knill demonstrated a fault-tolerant quantum computation scheme based on concatenated error-detecting codes and postselection with a simulated error threshold of $3\%$ over the depolarizing channel. We show how to use Knill's postselection scheme in a practical two-dimensional quantum architecture that we designed with the goal to optimize the error correction properties, while satisfying important architectural constraints. In our 2D architecture, one logical qubit is embedded in a tile consisting of $5\times 5$ physical qubits. The movement of these qubits is modeled as noisy SWAP gates and the only physical operations that are allowed are local one- and two-qubit gates. We evaluate the practical properties of our design, such as its error threshold, and compare it to the concatenated Bacon-Shor code and the concatenated Steane code. Assuming that all gates have the same error rates, we obtain a threshold of $3.06\times 10^{-4}$ in a local adversarial stochastic noise model, which is the highest known error threshold for concatenated codes in 2D. We also present a Monte Carlo simulation of the 2D architecture with depolarizing noise and we calculate a pseudo-threshold of about $0.1\%$. With memory error rates one-tenth of the worst gate error rates, the threshold for the adversarial noise model, and the pseudo-threshold over depolarizing noise, are $4.06\times 10^{-4}$ and $0.2\%$, respectively. In a hypothetical technology where memory error rates are negligible, these thresholds can be further increased by shrinking the tiles into a $4\times 4$ layout.

Authors: Barkova N. Yu.
Published: March 2021

The article considers ways to use the technology of radio frequency identification of data in retail companies. The author studies the traditional directions of using RFID technology, such as identification of data on the goods carried out at its acceptance, tracking the movement of goods along the supply chain, accounting of commodity units when loading into the vehicle and when picking the order, inventory of the goods. The paper also considers promising, but at the moment little common areas of application of technology in retail: personal digital assistants for managing the placement of goods on the shelves of the store, “smart fitting,” systems for automatic payment of goods and some others. Today, RFID technology can also be used for marketing research, to prevent theft in stores, to organize an improved customer service, to create inventory management systems. The author highlights the advantages received by retailers when applying RFID technology, and the barriers that prevent its active implementation.

Understanding Conformational Entropy in Small Molecules
Authors: Chan Lucian , Morris Garrett , Hutchison Geoffrey
Published: March 2021

The calculation of the entropy of flexible molecules can be challenging, since the number of possible conformers grows exponentially with molecule size and many low-energy conformers may be thermally accessible. Different methods have been proposed to approximate the contribution of conformational entropy to the molecular standard entropy, including performing thermochemistry calculations with all possible stable conformations, and developing empirical corrections from experimental data. We have performed conformer sampling on over 120,000 small molecules generating some 12 million conformers, to develop models to predict conformational entropy across a wide range of molecules. Using insight into the nature of conformational disorder, our cross-validated physically-motivated statistical model can outperform common machine learning and deep learning methods, with a mean absolute error ≈4.8 J/mol•K, or under 0.4 kcal/mol at 300 K. Beyond predicting molecular entropies and free energies, the model implies a high degree of correlation between torsions in most molecules, often as- sumed to be independent. While individual dihedral rotations may have low energetic barriers, the shape and chemical functionality of most molecules necessarily correlate their torsional degrees of freedom, and hence restrict the number of low-energy conformations immensely. Our simple models capture these correlations, and advance our understanding of small molecule conformational entropy.
Elongation of Triplet Lifetime Caused by Intramolecular Energy Hopping in Diphenylanthracene Dyads Oriented to Undergo Efficient Triplet–Triplet Annihilation Upconversion
Authors: Kanoh Masaya , Matsui Yasunori , Honda KIyomasa , Kokita Yuto , Ogaki Takuya , Ohta Eisuke , Ikeda Hiroshi
Published: March 2021

Triplet–triplet annihilation (TTA)-assisted photon upconversion (TTA-UC) in three dyads (DPA–Cn–DPA), comprised of two diphenylanthracene (DPA) moieties connected by nonconjugated C1, C2, and C3 linkages (Cn), has been investigated. The performance of these dyads as energy acceptors in the presence of the energy donor platinum octaethylporphyrin are characterized by longer triplet lifetimes (τT) and different TTA rate constants than those of the parent DPA. The larger tT of the linked systems, caused by “Intramolecular Energy Hopping” in the triplet dyad 3DPA*–Cn–DPA, results in a low threshold intensity, a key characteristic of efficient TTA-UC.
Exploring Chemical Reaction Space With Reaction Difference Fingerprints and Parametric t-SNE
Authors: Andronov Mikhail , Fedorov Maxim , Sosnin Sergey
Published: March 2021

Humans prefer visual representations for the analysis of large databases. In this work, we suggest a method for the visualization of the chemical reaction space. Our technique uses the t-SNE approach that is parameterized by a deep neural network (parametric t-SNE). We demonstrated that the parametric t-SNE combined with reaction difference fingerprints could provide a tool for the projection of chemical reactions onto a low-dimensional manifold for easy exploration of reaction space. We showed that the global reaction landscape, been projected onto a 2D plane, corresponds well with already known reaction types. The application of a pretrained parametric t-SNE model to new reactions allows chemists to study these reactions in a global reaction space. We validated the feasibility of this approach for two marketed drugs: darunavir and oseltamivir. We believe that our method can help to explore reaction space and will inspire chemists to find new reactions and synthetic ways.
Etching and Polymerization Reactions of Alkoxythiophenes in HKUST-1: Choosing Between Filled and Core-Shell MOF/Polymer Composite Structures
Authors: James William , Sullivan Colette M. , Marshall Nicholas
Published: March 2021

In an earlier report, we found that neat 3,4-ethylenedioxythiophene (EDOT) directly reacts with HKUST-1 to form a core-shell composite in which the HKUST-1 surface is coated with conjugated polymer, while unsubstituted thiophenes formed a filled composite where polythiophene is contained in the MOF's pores. In this work, we found that EDOT and 3-methoxythiophene (3MOT), which react in the neat form to form core-shell composites, can be loaded into HKUST-1 pores without reaction when dissolved in hexanes. To a lesser extent, 3-hexyloxythiophene (3HOT) can be loaded in the same way. These hexane-loaded composites can then be heated, resulting in the formation of a 'filled' composite. This finding allows us to choose to prepare either a core-shell or a filled composite by selecting reaction conditions. The process of heating with alkoxythiophenes results in a morphology change in the HKUST-1 material. Composites were characterized by nitrogen sorption measurements, powder X-ray diffraction, and vibrational spectroscopy.
HDX-MS Combining Molecular Dynamics Simulation Reveals Structural Basis of Transcriptional Coactivator PC4 Binding to a Platinum Crosslinked Double-Stranded DNA

Published: March 2021

Human nuclear protein positive cofactor PC4 is a DNA-binding protein, and plays an important role in the early response to DNA damage by recognizing single-stranded oligodeoxynucleotide domain and facilitating the subsequent steps of DNA repair. Our group previously discovered that PC4 selectively binds to a double-stranded oligodeoxynucleotide (dsODN) damaged by a trans-platinum anticancer complex, trans-[PtCl2(NH3)(thiazole)] (trans-PtTz). However, the molecular basis of this unique recognition and interaction remained unclear. In this work, amide hydrogen/deuterium exchange mass spectrometry (HDX-MS) was applied to dissect the interaction interface between PC4 and a 15-mer double-stranded oligodeoxynucleotide crosslinked by trans-PtTz (trans-PtTz-dsODN). Global deuterium uptake suggested a 1:1 binding stoichiometry of PC4 to trans-PtTz-dsODN. Local deuterium uptake revealed that the flexible N-terminal loop and the β3 – β5-sheet played key roles in the recognition and interaction between PC4 and trans-PtTz-dsODN. In order to locate the key amino acid residues, molecular dynamics simulation was employed, demonstrating that PC4 binds to the trans-PtTz-dsODN at the minor groove via strong H-bonds with the nucleobases of the complementary strand. The minor groove width was broadened to adapt for the binding of PC4. Arg86 residue in PC4 was shown to dominate the recognition and interaction, which was verified by electrophoretic mobility shift assays. This work profiles the detailed interaction mechanism of PC4 with trans-PtTz damaged dsODN, and the combination use of HDX-MS and molecular dynamics simulation provides a new paradigm for the future research of the cellular response to the platinum induced DNA damage.
Operando Monitoring the Insulator-Metal Transition of LiCoO2
Authors: Flores Eibar , Mozhzhukhina Nataliia , Aschauer Ulrich , Berg Erik
Published: March 2021

LiCoO2 (LCO) is one of the most-widely used cathode active materials for Li-ion batteries. Even though the material undergoes an electronic two-phase transition upon Li-ion cell charging, LCO exhibits competitive performance in terms of rate capability. Herein the insulator-metal transition of LCO is investigated by operando Raman spectroscopy complemented with DFT calculations and a newly-developed sampling volume model. We confirm the presence of a Mott insulator α-phase at dilute Li-vacancy concentrations (x > 0.87) that transforms into a metallic β-phase at x < 0.75. In addition, we find that the charge-discharge intensity trends of LCO Raman-active bands exhibit a characteristic hysteresis, which, unexpectedly, narrows at higher cycling rates. When comparing these trends to a newly-developed numerical model of laser penetration into a spatially-heterogeneous particle we provide compelling evidence that the insulator-metal transition of LCO follows a two-phase route at very low cycling rates, which is suppressed in favor of a solid-solution route at rates above 10 mA/gLCO (~C/10). The observations explain why LCO exhibits competitive rate capabilities despite being observed to undergo an intuitively slow two-phase transition route: a kinetically faster solid-solution transition route becomes available when the active material is cycled at rates >C/10. Operando Raman spectroscopy combined with sample volume modelling and DFT calculations is shown to provide unique insights into fundamental processes governing the performance of state-of-the-art cathode materials for Li-ion batteries.

Balancing Self-Healing and Shape Stability in Dynamic Covalent Photoresins for Stereolithography 3D Printing
Authors: Durand-Silva Alejandra , Cortés-Guzmán Karen , Johnson Rebecca , Perera Sachini , Smaldone Ron
Published: March 2021

Dynamic covalent bonds impart new properties to 3D printable materials that help to establish 3D printing as an accessible and efficient manufacturing technique. Here, we studied the effect of a thermally reversible Diels-Alder crosslinker on the shape stability of photoprintable resins and their self-healing properties. Resins containing different concentrations of dynamic covalent crosslinks in a polyacrylate network showed that the content of dynamic crosslinks plays a key role in balancing shape stability with self-healing ability. The shape stability of the printed objects was evaluated by measuring the dimensional changes after thermal treatment. The self-healing efficiency of the 3D printed resins was characterized with a scratch test and tensile testing. A dynamic covalent crosslink concentration of 1.8 mol % was enough to provide 99% self-healing efficiency without disrupting the shape stability of the printed objects. Our work shows the potential of dynamic covalent bonds in broadening the availability of 3D printable materials that are compatible with vat photopolymerization.

Published: March 2021

We present the covalent coating of chemically exfoliated molybdenum disulfide (MoS2) based on the polymerization of functional acryl molecules. The method relies on the efficient diazonium anchoring reaction to provoke the in situ radical polymerization and covalent adhesion of functional coatings. In particular, we successfully implement hydrophobicity on the exfoliated MoS2 in a direct, fast, and quantitative synthetic approach. This approach represents a simple and general protocol to reach dense and homogeneous functional coatings on 2D materials.
Surface Electronic State Mediates Proton Transfer at Metal Nanoscale Interface for Catalytic Hydride Reduction of −NO2 to −NH2
Authors: Shan Bingqian , Zhou Jiafeng , Ding Meng , Hu Xiao-Dan , Zhang Kun
Published: March 2021

Concerted electron and proton transfer is a key step for the reversible conversion of molecular hydrogen in both heterogeneous nanocatalysis and metalloenzyme catalysis. (Gabor A. Somorjai, et al. PNAS, 2016, 113, 5159–5166) However, the activation mechanism involving electron and proton transfer dynamic remains elusive. (Starla D. Glover and Leif Hammarström et al., J. Am. Chem. Soc. 2021, 143, 560−576.) With the most widely used catalytic hydride reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) as a model reaction, we evaluate the catalytic activity of noble metal NPs trapped in porous silica in aqueous NaBH4 solution. By virtue of a novel combination of catalyst design, reaction kinetics, isotope labeling, and multiple spectroscopic techniques, we counter-intuitively demonstrates that, the hydrogen resource of the final product of 4-AP by hydride reduction is not originated from the NaBH4 reduced, and that metal NPs (Ag/Pt/Pd) is not a real catalytic active site for surface electron mediation. (Avelino Corma etal., Angew. Chem. Int. Ed. 2007, 46, 7266 –7269; ACS Catal. 2015, 5, 7114−7121.). A completely new ‘Surface Electronic State Mediated Proton Transfer’ mechanism was proposed to understand the catalytic hydride reduction of −NO2 to −NH2 at metal nanoscale interface. The similar concerted electron and proton transfer dynamic was only recently observed in the [FeFe]-hydrogenases for reversible proton reduction. (Gregory A. Voth et al., J. Phys. Chem. B 2013, 117, 4062−4071; J. Chem. Phys. 2014, 141, 22D527; Juan C. Fontecilla-Camps et al., Chem. Rev. 2007, 107, 4273-4303.) We believed that current research provide a completely new insights into the working mechanism of nanocatalysis and metalloenzyme catalysis involved by electron and proton transfer.
Peripheral Decoration of Multi-Resonance Molecules as a Versatile Approach for Simultaneous Long-Wavelength and Narrowband Emission
Authors: Qi Yanyu , Ning Weimin , Zou Yang , Cao Xiaosong , Gong Shaolong , Yang Chuluo
Published: March 2021

High device efficiency and color-purity are the two essentials for high-quality organic light emitting diodes (OLEDs). Multi-resonance (MR) molecules show great potentials for high color-purity OLEDs due to their sharp emission bands. However, most MR molecules exhibit emission limited from deep-blue to green spectral region. Herein, through peripherally decorating MR emitter with electron donors, we demonstrated a new approach enabling the emission spectra of MR emitters red-shift while retaining narrowband emission. By manipulating the numbers and electron-donating abilities of the peripheries, the first narrowband yellow emitter with emission maxima of 562 nm and a full-width at half-maximum (FWHM) of 30 nm is realized. Highly efficient OLEDs with external quantum efficiency of over 24% and excellent color purity are fabricated by employing these newly developed MR molecules as emitters.
Determination of Lithium in Human Serum by Isotope Dilution Atomic Absorption Spectrometry

Published: March 2021

The therapeutic dose of lithium (Li) compounds, which are widely used for the treatment of psychiatric and hematologic disorders, is close to its toxic level; therefore, drug monitoring protocols are mandatory. Herein, we propose a fast, simple, and low-cost analytical procedure for the traceable determination of Li concentration in human serum, based on the monitoring of the Li isotope dilution through the partially resolved isotope shift in its electronic transition around 670.80 nm using a commercially available high-resolution continuum source graphite furnace atomic absorption spectrometer. With this technique, serum samples only require acidic digestion before analysis. The procedure requires three measurements—an enriched 6Li spike, a mixture of a certified standard solution and spike, and a mixture of the sample and spike with a nominal 7Li/6Li ratio of 0.82. Lanthanum has been used as an internal spectral standard for wavelength correction. The spectra are described as the linear superposition of the contributions of the respective isotopes, each consisting of a spin-orbit doublet, which can be expressed as Gaussian components with constant spectral position and width and different relative intensity, reflecting the isotope ratio in the sample. Both, the spectral constants and the correlation between isotope ratio and relative band intensity have been experimentally obtained using commercially available materials enriched with Li isotopes. The procedure has been validated using five human serum certified reference materials. The results are metrologically comparable and compatible to the certified values. The measurement uncertainties are comparable to those obtained by the more complex and expensive technique, isotope dilution mass spectrometry.
Structure, Dynamics, and Ligand Recognition of Human-Specific CHRFAM7A (Dupα7) Nicotinic Receptor Linked to Neuropsychiatric Disorders
Authors: Liu Danlin , de Souza Cunha Joao Victor , Ahmed Ayaz , Bronowska Agnieszka K.
Published: March 2021

Cholinergic α7 nicotinic receptors encoded by the CHRNA7 gene are ligand-gated ion channels directly related to memory and immunomodulation. Exons 5-7 in CHRNA7 can be duplicated and fused to exons A-E of FAR7a, resulting in a hybrid gene known as CHRFAM7A, unique to humans. Its product, denoted herein as Dupα7, is a truncated subunit where the N-terminal 146 residues of the ligand binding domain of the α7 receptor have been replaced by 27 residues from FAM7. Dupα7 has a negative effect on the functioning of α7 receptors associated with neurological disorders, including Alzheimer's diseases and schizophrenia. However, the stoichiometry for the α7 nicotinic receptor containing dupα7 monomers remains unknown. In this work, we developed computational models of all possible combinations of wild-type α7 and dupα7 pentamers and evaluated their stability via atomistic molecular dynamics and coarse-grain simulations. We assessed the effect of dupα7 subunits on the Ca2+ conductance using free energy calculations. We showed that receptors comprising of four or more dupα7 subunits are not stable enough to constitute a functional ion channel. We also showed that models with dupα7/ α7 interfaces are more stable and are less detrimental for the ion conductance in comparison to dupα7/ dupα7 interfaces. Based on these models, we used protein-protein docking to evaluate how such interfaces would interact with an antagonist, α-bungarotoxin, and amyloid Aβ42. Our findings show that the optimal stoichiometry of dupα7/ α7 functional pentamers should be no more than three dupα7 monomers, in favour of a dupα7/α7 interface in comparison to a homodimer dupα7/dupα7 interface. We also showed that receptors bearing dupα7 subunits are less sensitive to Aβ42 effects, which may shed light on the translational gap reported for strategies focused on nicotinic receptors in Alzheimer's Disease research.
Transitioning Service Design within Government: An exploration of how the role of Service Design within Central Government agencies might benefit from Transition Design as a key artbiter of social change
Authors:   , Westwater Logan
Published: March 2021

This research considers how Transition Design, an emergent design provocation, could be used to grow the role of Service Design within New Zealand Central Government. Leading this investigation is the assertion that currently within Central Government agencies a re-evaluation and re- scoping of the contributions that Service Design can make towards the resolution, mitigation or navigation of the complex social, cultural, political and economic issues these agencies now face is required. This study also asserts that Service Design could play a more impactful role within Central Government as an arbiter of change. To achieve this, the role of Service Design needs to be redefined and service designers’ skills recalibrated. This research considers how Transition Design could be used to achieve this aim.

Transition Design, as a provocation not a manifesto, challenges the existing paradigms which characterise Service Design and illuminates radical pathways for societal transitions to more sustainable futures. This study identifies opportunities within New Zealand Central Government structures, systems and processes to use Transition Design as a model to challenge existing modes and having done so, enable more radical social and environmental change.

A critical component of this research is a series of interviews conducted with Service Design practitioners currently working within or alongside New Zealand Central Government. These interviews were analysed and used to help define areas or stages of Service Design that Transition Design interventions could be tested against. Importantly, these interviews also served to develop new models that illustrated areas in which Transition Design methods or ideologies could be applied within the Central Government context. A second round of interviews critiqued the practical application of Transition Design within current and towards future Service Design practice. Having identified many of the key barriers currently limiting the effectiveness of Service Design and service designers working within Central Government, this research posits that the provocations exhibited within Transition Design will go a long way to enabling the expansion of both Service Design’s role and service designer’s capacities, capabilities in the resolution, mitigation and navigation of the complex social, cultural, political and economic issues that need to be addressed by New Zealand Central Government.

Published: March 2021

One way to find out the quality of exam questions is by looking at the rules for writing exam questions made based on the subject or discussion contained in the learning plan document. Therefore, the exam questions that are arranged must be adjusted to the main material in each subject learning achievement. This study discusses the implementation of the concept in information retrieval systems using the Vector Space Model method. The Vector Space Model method has an advantage in query matching because it is able to match only part of the query with existing documents. In addition, the Vector Space Model method is also easy to adapt by adjusting parameters, including weighting parameters. The weighting calculation for each term that appears in the document uses TF-IDF. The purpose of this study is to design an information retrieval system to find the suitability of the exam question query with the subject contained in the learning plan document. The suitability is sorted based on the similarity value of the calculation results, from the largest value to the smallest value in the form of a percentage.

Tuberculosis is a contagious infectious disease caused by Mycobacterium tuberculosis. The risk level of transmission of pulmonary tuberculosis with positive smear of acid-resistant bacteria (BTA). BTA is greater hight risk than pulmonary tuberculosis with negative smear. This study aims to predict areas of the number of new BTA positive tuberculosis cases in Aceh Besar district spatially using the kriging method. The data used are secondary data coordinate the point of the number of new cases of positive smear tuberculosis in each puskesmas in the province of Aceh in 2015-2017. The experimental semivariogram calculation is the first step in estimating using ordinary kriging, which is a reference for getting the parameters to be used in theoretical semivariogram calculations. In this case, the semivariogram suitable for new cases of smear positive tuberculosis is the one of the Spherical model. The sill value used is 126.530, the nugget=62, while the range used is based on the distance of each class = 0.158. The results of the analysis showed that the regions with the lowest positive BTA Tuberculosis prediction cases were around Pulo Aceh Sub-District, Montasik Sub-District, and Indrapuri Sub-District, with less than 15 cases. Whereas the region with the most positive predictions of new cases of BTA Tuberculosis was around Baitussalam Sub-District and Jantho City, with more than 30 cases.

Penelitian ini menguji pengaruh International Financial Reporting Standards (IFRS) Terhadap Kualitas Informasi Akuntansi dan Kualitas Laba  yang diukur dengan relevansi informasi. Sampel dalam penelitian ini adalah perusahaan manufaktur yang terdaftar di BEI dengan tahun pengamatan selama delapan tahun yaitu empat tahun sebelum (2008-2011) dan empat tahun sesudah (2013-2014) dan diperoleh sampel sebanyak 31 sampel perusahaan. Hasil penelitian menunjukan bahwa penerapan IFRS mampu meningkatkan kualitas laba yang diukur dengan relevansi informasi akuntansi. Hasil ini juga menunjukkan bahwa terjadi peningkatkan relevansi nilai Book Value. Pada dimensi laba bersih perlembar saham (EPS), meskipun nilai  coefficient  EPS mengalami penurunan setelah penerapan IFRS, tetapi nilai EPS masih tetap memiliki arah yang positif terhadap harga saham. Dengan demikian, nilai relevansi BV lebih tinggi dibandingkan nilai relevansi EPS setelah penerapan IFRS. Kata Kunci : IFRS, Relevansi Informasi Akuntansi, Informasi Akuntansi
MATERNIDADE POLÍTICA: TRAJETÓRIAS DE VIDA, EDUCAÇÃO E LUTAS POR DIREITOS

O presente artigo trata da trajetória de quatro mulheres e mães que têm filhos com paralisia cerebral, salvo uma, que ela própria tem PC[1]. Suas vidas, valores, aprendizagens e experiências mudaram significativamente quando os filhos nasceram. Enfrentando grandes desafios diários e valorizando todas as conquistas, elas tiveram que lutar para garantir direitos, respeito e oportunidades. O desejo de acessar a escola as levou ao encontro de ideias, estratégias de resistência, experiências comuns e a descoberta de força. A Educação foi, inicialmente, o fator agregador e impulsionador que as motivou. A inexistência ou insuficiência da atuação do poder público, a ignorância, os preconceitos, a violência e os estigmas, constituíram-se as principais barreiras presentes nas vidas dessas mulheres e de suas filhas e filhos. A pesquisa, aqui apresentada, tem o objetivo de trazer narrativas que revelam sentimentos, resistência, interesses e desejos. As quatro mulheres e mães participantes da pesquisa, foram entrevistadas no período da pandemia de 2020, de maneira remota e através de videochamada. Para embasar as discussões e articulações teóricas, foram utilizados dentre outros, os/as autores/as: Guacira Louro (2019) refletindo sobre o corpo e identidade; David Le Breton (2013) para pensar o corpo sob uma perspectiva antropológica; Andrew Solomon (2013) com a percepção da relação pais, filhos e a identidade; Elisabeth Badinter (1985) e a reflexão sobre maternidade e amor materno; Maria Tereza Mantoan (2003) e a educação inclusiva; Naomi Wolf (2020) trazendo as construções históricas sobre beleza.
Studying of Plasma- Polymerized Pyrrole at Variable Gas Flow Rates Via Plasma Jet
Authors: Kadhem Saba Jawad
Published: March 2021

In this manuscript has investigated the synthesis of plasma-polymerized pyrrole (C4H5N) nano-particles prepared by the proposed atmospheric pressure nonequilibrium plasma jet through the parametric studies, particularly gas flow rate (0.5, 1 and 1.5 L/min). The plasma jet which used operates with alternating voltage 7.5kv and frequency 28kHz. The plasma-flow characteristics were investigated based on optical emission spectroscopy (OES). UV-Vis spectroscopy was used to characterize the  oxidization  state for polypyrrole. The major absorption appears around 464.1, 449.7 and 435.3  nm at the three flow rate of argon gas. The chemical composition and structural properties of the contained samples which synthesized at 0.5 L/min as a argon flow rate were analyzed by scanning electron microscopy (SEM), Fourier transformation infrared spectroscopy (FTIR), Raman spectroscopy and X-ray diﬀraction (XRD). SEM point to a uniform distribution of polypyrrole (PPY) nanoparticles matrix. XRD technique showed a semicrystalline pattern for PPY)thin film. It is expected, that the high-quality plasma polymer grown by atmospheric pressure plasma jet method contributes to serving as conducting materials.
Effect of Web Stiffeners on The Flexural Behavior of Composite GFRP- Concrete ‎Beam Under Impact Load
Authors: Ali Safaa Ibraheem , Allawi Abbas A.
Published: March 2021

In this paper, numerical and experimental studies on the elastic behavior of glass fiber reinforced ‎polymer (GFRP) with stiffeners in the GFRP section's web (to prevent local buckling) are presented. ‎The GFRP profiles‎ were connected to the concrete deck slab by shear connectors. Two full-scale simply supported ‎composite beams (with and without stiffeners) were tested under impact load (three-point load) to ‎assess its structural response. The results ‎proved that the maximum impact force, maximum ‎deflection, damping time, and ‎damping ratio of the composite beam were affected by the GFRP ‎stiffeners‎. The experimental results indicated that the damping ratio and deflection were diminished compared to hybrid beam without stiffeners by ‎‎16% and 22%, respectively, and increasing damping time‏ by 26%. Finite element models were used to study pre-failure behavior. ‎ The numerical modeling results showed good agreement with experimental data in terms of loading path and ‎final load. The damping ratio and midspan deflection values were greater than the experimental ‎values by 6% and 12%, respectively.

Dalam kebudayaan ada hal yang tidak asing lagi bagi kita semua. Banyak sekali perbedaan yang menonjol diri masyarakat. Perbedaan ini seperti kebiasaan dari erilaku, dan cara hidup yang dimiliki seseorang yang disebut budaya. Kebudayaan itu sifatnya lebih menuntut seseorang diluar kemauan, tapi ketika juga harus tau kalau itu adalah budaya, maka yang melakukannya. Banyak dari orang memahami bahwa budaya itu lahir dari suatu kelompok yang disepakati banyak orang. Tanpa kita sadari, bahwa kebiasaan yang kita lakukan itu lah budaya dalam diri kita. namun dalam diri kita ada budaya yang buruk, dan budaya yang baik. Walaupun budaya itu sendiri seolah seperti memaksa kehendak seseorang, tapi kebudayaan itu sendiri juga jangan sampai menghilangkan jati diri seseorang. Walaupun jaman teknologi sudah berkembang, seharusnya budaya tidak dihilangkan. Justru sebaliknya budaya harus tetap diperkenalkan kepada generasi muda, agar kebudayaan yang dimiliki sekelompok masyarakat tidak luntur. Justru teknologi harus digunakan memperkembangkan kebudayaan yang ada.

Ferdinando Galiani’s Newtonian Social Mathematics
Authors: Patalano Rosario
Published: March 2021

The evolution of Ferdinando Galiani’s thought toward social mathematic has been neglected by scholars, and his attempt to establish political arguments on the analytical basis remains unexplored. The non-systematic nature of Galiani’s intuitions, due to his laziness, largely justifies this underestimation of his scientific program. This paper intends to show that the mature abbé Galiani follows an intellectual itinerary autonomous and parallel to that followed by Marquis de Condorcet in the same years. The anti-Physiocratique querelle represents Galiani’s methodological maturation. In contrast with Physiocratic economic doctrine, based on the primacy of deductive methodology, Galiani claims for economic science the realism of circumstance against aprioristic axiomatic hypotheses and rationalist generalizations. Galiani’s project, substantially similar to Marquis de Condorcet’s approach to social science, can be defined as Newtonian social mathematics opposed to Physiocratic Cartesian social mathematics.
