Effects of Visual Metaphors on Enhancing the Power of Advertisements
Authors: Birdsell Brian J. , Tatsuta Natsuko , Nakamura Hiroaki
Published: August 2022

Visual metaphors deliberately deviate from the literal representation of an object. The resulting incongruity has the potential to be more engaging and memorable for the viewer and thus are frequently used as a design feature in advertisements. Recently, researchers have begun to more thoroughly examine the advantages that visual metaphors play in advertisements and this study contributes to this growing body of research. Two experiments were conducted using sets of paired advertisements for the same product or social awareness campaign based on one of them being a visual metaphor and the other being a visual non-metaphor to explore if there was a visual- metaphor effect. In Experiment 1, participants rated these adverts based on three criteria, effectiveness, engagement, and a metaphorical framing effect along with an open-ended question. In Experiment 2, two additional variables were included, comprehensibility and creativity. Results support the view that visual metaphors tend to be more engaging and perceived to be more creative. However, this does not always result in them being viewed as more effective adverts.
Financial literacy and crime incidence

Published: August 2022

Financial literacy is a determinant of individual wealth accumulation and social well-being. In this study, we examine the relationship between financial literacy and crime incidence using financial literacy data and crime data in the U.S. from 2009 to 2018. We posit that citizens’ financial literacy is negatively associated with the crime rate because financially literate citizens are better at managing their wealth and improving their economic condition. They are less likely to have unfulfilled basic needs, and thus are less prone to crimes, especially crimes driven by economic need. We find that the financial literacy of citizens is negatively associated with crime rates. Furthermore, examining on a disaggregated basis, financial literacy is negatively associated with violent crimes and property crimes. Our findings reveal the necessity of mandating financial education programs in workplaces and highlighting the role of financial literacy in corporate governance. This study is the first to empirically address the criminological consequences of low financial literacy and underline the way to improve social security by increasing people’s financial condition

Published: August 2022

Lignocellulose is the most abundant natural biopolymer on earth and a
potential raw material for the production of fuels and chemicals.
However, only some organisms such as bacteria and fungi produce the
necessary enzymes to metabolize it. In this work we detected the
presence of extracellular cellulases in the genome of five species of
Scenedesmus. These microalgae grow in both, freshwater and
saltwater regions as well as in soils, displaying highly flexible
metabolic properties. The comparison of sequences of the different
cellulases with hydrolytic enzymes from other organisms by means of
multi-sequence alignments and phylogenetic trees showed that these
enzymes belong to the families of glycosyl hydrolases 1, 5, 9 and 10. In
addition, most of these presented a greater similarity of sequence with
enzymes from invertebrates, fungi, bacteria and other microalgae than
with cellulases from plants; and the 3D modeling data obtained showed
that both the main structures of the modeled proteins and the main amino
acid residues implicated in catalysis and substrate binding are well
conserved in Scenedesmus enzymes. We propose that these
cellulase-producing phototrophic microorganisms could act as catalysts
for the hydrolysis of cellulosic biomass fueled by sunlight.

Published: August 2022

Biomass-derived syngas is prone to leakage during transportation. To safely use biomass-derived syngas, we need to study the combustion characteristics of material syngas the purpose of this paper is: at T = 303 K, P = 0.1 MPa, under the condition of the spherical expansion flame method, calculate the laminar burning velocity, and used the Chemkin module of ANSYS to simulate four mechanisms (GRI-3.0?FFCM-1?Li-2015?SanDiego +NOx-2018) to compare, select more appropriate reaction mechanism through experimental data for related research. It was found that the chemical reaction mechanism of GRI-3.0 is more in line with the experimental results. It is found that the experimental results are in good agreement with the linear extrapolation method. When the H2 concentration in-creases from 22-42%, the peak laminar burning velocity moves in the direction of the lean fuel side. When the H2 concentration increases to 42%, the laminar burning velocity is the fastest, reaching 0.78 m/s. The effect of H2 on thermal diffusivity is high. When H2 concentration reaches 42%, its thermal diffusivity is much higher than other gas components. The adiabatic flame temperature of F1 (22% H2, 45% CO, 9.6% CH4, 23.4% CO2)-air mixtures is the highest, approaching 2196 K. The peak adiabatic flame temperature of F5 (42% H2, 25% CO, 9.6% CH4, 23.4% CO2)-air mixtures is 2082 K, which is comparatively low. Nonetheless, the H2 concentration in F5-air mixtures is higher than that in F1-air mixtures, indicating that H2 has less influence on adiabatic flame temperature than CO. The positive reactions to accelerate laminar burning velocity mainly include R99, R38, and R46. The R52 and R35 can inhibit laminar burning velocity. There are many factors affecting laminar burning velocity, among which high reactive free radicals are the main factors, and the competition between chain branching reaction and chain termination reaction for high reactive free radicals also affects laminar burning velocity. With the increase of concentration of H2, participate in the reaction of the molar mass fraction of highly reactive free radicals and the laminar burning velocity.

Published: August 2022

Mesencephalic astrocyte-derived neurotrophic factor (MANF) is an emerging regulator in metabolic control. Hypothalamic pro-opimelanocortin (POMC) neurons play critical roles in maintaning whole-body energy homeostasis. Whether MANF in POMC neurons is required for the proper regulation of energy balance remains unknown. Here, we showed that mice lacking MANF in POMC neurons were more prone to develop diet-induced obesity. In addition, the ablation of MANF induced endoplasmic reticulum (ER) stress and leptin resistance in the hypothalamus, reduced POMC expression and post-translational processing, and ultimately decreased sympathetic nerve activity and thermogenesis in brown adipose tissue (BAT). Conversely, MANF overexpression in hypothalamic POMC neurons attenuated ER stress, increased POMC expression and processing, and then stimulated sympathetic innervation and activity in BAT, resulting in increased BAT thermogenesis, thus protecting mice against dietary obesity. Overall, our findings provide evidence that MANF is required for POMC neurons to combat obesity.

Orta Çağ’da Selçuklular ve diğer Anadolu beylikleri arasında pek çok yönden mücadeleler yaşanmıştır. Bu mücadelelerin bir tarafını da entelektüel bilgiye sahip olmak oluşturmuştur. Bunun için Anadolu beyleri Dârü’s-sıhha, Dârü’ş-şifâ ve Mâristanlar inşâ etmişler ve bu binalarda çalışanlar için her türlü gereksinimi karşılamaya çalışmışlardır.

Özellikle Haçlı Devletleri kurulduktan sonra Doğu Akdeniz’den Anadolu’ya doğru kayan ticaret yolları bölgede çok sayıda kervansaray kurulmasına sebep olmuştur. Güvenli ticaret yollarının etrafında bulunan sağlık binaları birçok hekimin Ortadoğu’dan Anadolu’ya geçmesine vesile olurken burada sentezlenmiş olan Yunan-İran-Hint tıbbının İslâm dünyası içinde geliştirilmiş hali Anadolu’ya taşınmıştır.

Bu tıbbi bilgi hastalıkların tedavisinde öd ağacı, misk, kâfur, belsam ve helile gibi pek çok bitkinin kullanılmasını mümkün kılıyordu. Fakat bu bitkilerin hepsi Anadolu’da bulunamazdı. Sağlık binalarının yakınlarından geçen ve bilinen Dünya’nın her yerine ulaşan ticaret yolları vasıtasıyla bitkiler bu binalarda çalışan entelektüellere sağlanmaya başlandı.

Bitkilerden bazıları ipek yolu üzerinden temin edilirken bazıları ise Çin’in doğu kıyılarında bulunan ticaret limanlarından çıkıp Serendib’e bağlanıyor ve Baharat yolundaki bitkilerle birlikte kuzey-batı yolundan Anadolu’ya doğru getiriliyordu. Ayrıca Endülüs yolu da Orta Çağ’da bitki taşınan ticaret yollarından biri idi.

Authors: Prihatiningsih Nur , Adi Djatmiko Heru , Lestari Puji
Published: August 2022

Rhizoctonia solani and Xanthomonas oryzae pv. oryzae (Xoo) are important pathogens causing severe damage on rice. It makes severe damage and is required for the management of the disease. One of the management of the disease is the use of endophytic bacteria. The purpose of this study was to determine the compatibility of endophytic bacteria as consortium, to examine the potency of the endophytic bacteria consortium against R. solani and Xoo and to understand the mechanism of inhibition of endophytic bacteria consortium against R. solani and Xoo. Assessment on the compatibility between endophytic bacteria was performed in a petridish using streak method. The endophytic bacterial consortium antagonism test against rice pathogenic fungi and bacteria was carried out in a completely randomized design with 2 treatments and 15 replications. The variables observed were the compatibility of endophytic bacteria, the percentage of inhibition and the zone of inhibition. The mechanism of inhibition was observed from changes in the form of pathogenic fungi and bacteriostatic or bactericidal. The results showed that among 12 compatible endophytic bacteria as constituents of the consortium, five isolates of endophytic bacteria showed strong and very strong growth with the other isolates. These isolates from Petanahan Kebumen, Karangwangkal Purwokerto and Sumbang Banyumas. The consortium of endophytic bacteria was able to suppress the growth of R. solani by 57.14% with antibiosis mechanism causing swelling of the mycelium and formed a red pigment. The endophytic bacteria consortium inhibited the growth of Xoo by 15 mm with a bacteriostatic antibiosis mechanism. Consortium endophytic bacteria can be used as an alternative to control plant diseases which also has the opportunity to be formulated and applied to plants.

Published: August 2022

The Covid-19 pandemic has affected the global economy and environment. The main victims of the covid-19 outbreak are Micro Small and Medium Enterprises (MSMEs), especially in developing countries due to the limited use of digital technology. Digital marketing is a strategic step that can be done by MSMEs to market their products without having to violate health protocols. Research methods use qualitative methods with an analytical descriptive approach. Descriptive research by collecting data based on factors that support the object of research, while qualitative research deals with ideas, perceptions, opinions, beliefs of people to be researched and everything that cannot be measured by numbers. The results showed that the difference in marketing before the pandemic and during the pandemic lies in the use of the internet. Digital marketing has only been widely known by the public since the pandemic, but people's understanding of the use of digital marketing is still quite low and needs to be improved so that marketing is done more effectively and efficiently.
Ancaman Impor Sampah Ilegal Terhadap Keamanan Lingkungan di Indonesia, 2016-2019
Authors: Shafira Amanda Raissa , Wibawa Satriya , Aditiany Savitri
Published: August 2022

Penelitian ini bertujuan untuk mengetahui bagaimana peningkatan impor sampah ilegal dapat mengancam keamanan lingkungan di Indonesia. Indonesia merupakan salah satu negara yang mengimpor limbah sebagai bahan baku untuk industri dalam negeri. Namun, sejak tahun 2018, peningkatan impor yang drastis mengungkap bahwa telah terjadi banyak kasus impor sampah ilegal yang masuk bersamaan dengan impor bahan baku, terutama kertas dan plastik. Penelitian ini menggunakan metode kualitatif studi kasus dengan menghimpun data dari wawancara serta literatur berupa buku, artikel, dan jurnal yang relevan. Analisis penelitian ini menggunakan konsep keamanan lingkungan yang merupakan bagian dari konsep keamanan manusia. Berdasarkan hasil penelitian, peneliti menemukan bahwa impor sampah ilegal yang terjadi di Indonesia selama tahun 2016 hingga 2019 telah mengancam keamanan lingkungan akibat pencemaran yang ditimbulkannya terhadap ketiga aspek lingkungan, yaitu air, tanah, dan udara. Impor skrap plastik dan kertas dengan kontaminan yang sangat tinggi, telah menyebabkan penumpukkan sampah di dalam negeri yang kemudian tidak bisa diolah kembali. Seluruh pencemaran terhadap ketiga aspek tersebut membuat lingkungan di sekitar pabrik yang mengimpor sampah ilegal menjadi tidak layak bagi manusia. Namun titik terang mulai terlihat sejak tahun 2019, di mana pemerintah Indonesia mulai memfokuskan perhatiannya terhadap masalah masuknya sampah ilegal ke dalam negeri.

Os Grandes Projetos Urbanos são empreendimentos plurifuncionais que demandam um longo tempo para serem concluídos. São concebidos sob uma lógica global-local em que o território se ajusta aos preceitos do capital como condição para se adequarem aos novos padrões de modernização dos espaços. A governança desses Grandes Projetos Urbanos evidencia o protagonismo privado, ainda que o Estado seja fundamental como agente regulador eviabilizador do negócio. Sendo assim, neste artigo são analisadas as relações de governança a partir do levantamento dos atores envolvidos, considerando aspectos ideacionais e funcionais que foram realizados para a implantação do grande projeto urbano denominado Reserva do Paiva, localizado na Região Metropolitana do Recife, em Pernambuco, Brasil. Dentre os aspectos evidenciados na pesquisa têm-se a governança no empreendimento, a gestão corporativa estabelecida, os atores da governança do empreendimento e a segregação socioespacial considerando o discurso de exclusividade e de preservação ambiental o que pressupõe maior confiabilidade e atratividade para classes de alto poder aquisitivo.
Mollic soils situated in non-Chernozem regions in Slovakia
Authors: Kobza Jozef
Published: August 2022

This study is focused on an evaluation of some important soil properties as a result of the genesis of mollic soils which are located outside of the main Chernozem regions in Slovakia. Several soil profiles selected from the Soil Monitoring Network in Slovakia were evaluated and interpreted. Unified analytical procedures used in soil monitoring system have been applied. Following soil indicators: pH, humus content, and qualitative components as humic acids (HA) and fulvic acids (FA) as well as the fractional composition of HA, the content of labile carbon (CL), potentially mineralisable nitrogen (Npot) have been analysed. Based on obtained results in more details, it may be said that the dark-coloured soils in non-Chernozem regions opposite dark-coloured soils in Chernozem regions have a higher content of labile carbon and higher index of lability as well as higher CL: Npot ratio. This indicator seems to be more significant than the often used C/N ratio. In addition, the darkcoloured soils in non-Chernozem regions are characteristic with higher content of aliphatic carbon as well as lower content of carboxylic groups (-COOH) and lower value of the optical parameter (E1%
6). These indicators in more detail are of higher interpretation value for a better evaluation of dark-coloured soils in non-Chernozem regions compared with similar soils in Chernozem regions.
Exergo-Environmental Optimization of a Diesel Engine

Published: August 2022

Currently, more than half of the road transport fleet uses diesel engines, which are often identified as the primary source of air pollution. This parameter is enough to optimize engine performance and emissions. The engine optimization can be done using several methods, the most notably by modifying the engine structure, changing the type of fuel using additives and biofuels, or achieving the optimal operating range of the engine. Modifying the engine structure and addition of different kinds of materials to optimize fuel is not recommended either due to necessity of vast time input, financial resources, or extensive research. However, the third way to achieve optimal engine performance conditions can be the most accessible option. According to the results, the best operational load for diesel engine is approx. 94–95% of the full load from the multi-objective optimization point of view, indicating that the optimum load can be achieved before the full load condition. At this point, the operator can achieve the brake power of 198.45 kW and brake thermal efficiency of 40.7% in the presence of brake specific fuel consumption of 0.226 kg·kWh−1. At this condition, CO2 emission is 124.85 g·kWh−1, NOx emission 7.34 g·kWh−1, CO emission 0.6 g·kWh−1, unburnt hydrocarbon emission approx. 0.009 g·kWh−1, and soot formation approx. 0.006 g·kWh−1. This point is equal to the exergy efficiency of approx. 35% and the exergy destruction of approx. 45%. In terms of endpoint results, this condition achieved the impact indices of 7.96E-007 in terms of human health, 0.105 PDF·m2·yr. in terms of ecosystem quality, 0.24 kg CO2 eq. in terms of climate change, and 12.96 MJ in terms of resources.

Stability kernel in finite games with perturbed payoffs
Authors: Emelichev Vladimir , Nikulin Yury
Published: August 2022

The parametric concept of equilibrium in a finite cooperative game of several players in a normal form is introduced. This concept is defined by the partitioning of a set of players into coalitions. Two extreme cases of such partitioning correspond to Pareto optimal and Nash equilibrium outcomes, respectively. The game is characterized by its matrix, in which each element is a subject for independent perturbations., i.e. a set of perturbing matrices is formed by a set of additive matrices, with two arbitrary Hölder norms specified independently in the outcome and criterion spaces. We undertake post-optimal analysis for the so-called stability kernel. The analytical expression for supreme levels of such perturbations is found. Numerical examples illustrate some of the pertinent cases.
Set-valued minimax fractional programming problems under ρ-cone arcwise connectedness
Authors: Das Koushik
Published: August 2022

In this paper, we consider a set-valued minimax fractional programming problem (MFP), where the objective as well as constraint maps are set-valued. We introduce the notion of ρ-cone arcwise connectedness of set-valued maps as a generalization of cone arcwise connected set-valued maps. We establish the sufficient Karush-Kuhn-Tucker (KKT) conditions for the existence of minimizers of the problem (MFP) under ρ-cone arcwise connectedness assumption. Further, we study the Mond-Weir (MWD), Wolfe (WD), and mixed (MD) types of duality models and prove the corresponding weak, strong, and converse duality theorems between the primal (MFP) and the corresponding dual problems under ρ-cone arcwise connectedness assumption.
Social choice, stable outcomes and deliberative democracy
Authors: Nurmi Hannu
Published: August 2022

It has turned out that all voting rules fail on some intuitively plausible desiderata. This has led some political scientists to argue that the notion of the will of the people is profoundly ambiguous and the absence of voting equilibria a generic state of a airs. As a constructive remedy to this some authors have introduced the idea of deliberative democracy. This view of democracy has much to recommend itself, most importantly the emphasis on individuals in devising the decision alternatives. Some empirical evidence also suggests that the deliberative institutions provide an escape from some of the most notorious incompatibility results in social choice theory. We shall critically examine this suggestion. The view emerging from this examination is that social choice theory and deliberative democracy are complementary, not competing approaches to democratic decision making.
Uniqueness of the Riccati operator of the non-standard ARE of a third order dynamics with boundary control
Authors: Lasiecka Irena , Triggiani Roberto
Published: August 2022

The Moore-Gibson-Thompson [MGT] dynamics is considered. This third order in time evolution arises within the context of acoustic wave propagation with applications in high frequency ultrasound technology. The optimal boundary feedback control is constructed in order to have on-line regulation. The above requires wellposedness of the associated Algebraic Riccati Equation. The paper by Lasiecka and Triggiani (2022) recently contributed a comprehensive study of the Optimal Control Problem for the MGT-third order dynamics with boundary control, over an infinite time-horizon. A critical missing point in such a study is the issue of uniqueness (within a specific class) of the corresponding highly non-standard Algebraic Riccati Equation. The present note resolves this problem in the positive, thus completing the study of Lasiecka and Triggiani (2022) with the final goal of having on line feedback control, which is also optimal.
On the robustness of the topological derivative for Helmholtz problems and applications
Authors: Leugering Günter , Novotny Antonio André , Sokolowski Jan
Published: August 2022

We consider Helmholtz problems in two and three dimensions. The topological sensitivity of a given cost function J(u
∈) with respect to a small hole B
∈ around a given point x
0 ∈ B
∈ ⊂ Ω depends on various parameters, like the frequency k chosen or certain material parameters or even the shape parameters of the hole B
∈. These parameters are either deliberately chosen in a certain range, as, e.g., the frequencies, or are known only up to some bounds. The problem arises as to whether one can obtain a uniform design using the topological gradient. We show that for 2-d and 3-d Helmholtz problems such a robust design is achievable.
Similarity measures for Atanassov’s intuitionistic fuzzy sets: some dilemmas and challenges
Authors: Szmidt Eulalia , Kacprzyk Janusz , Bujnowski Paweł
Published: August 2022

We discuss some aspects of similarity measures in the context of Atanassov’s intuitionistic fuzzy sets (IFSs, for short). IFSs, proposed in 1983, are a relatively new tool for the modeling and simulation and, because of their construction, present us with new challenges as far the similarity measures are concerned. Specifically, we claim that the distances alone are not a proper measure of similarity for the IFSs. We stress the role of a lack of knowledge concerning elements (options, decisions, etc.) and point out the role of the opposing (complementing) elements. We also pay attention to the fact that it is not justified to talk about similarity when one has not enough knowledge about the compared objects/elements. Some novel measures of similarity are presented.
El bandolerismo en Colombia
Authors: Castillo Gómez Luis Carlos
Published: August 2022

El gran historiador inglés, Eric Hobsbawm, en su texto Rebeldes primitivos (1983, p. 264), califica la Violencia en Colombia como “la mayor movilización armada de campesinos (ya sea como guerrilleros, bandoleros o grupos de autodefensa) en la historia reciente del hemisferio occidental, con la posible excepción de determinados períodos de la Revolución mexicana”. A partir de esta consideración, usando la categoría de bandolero social y explotando cientos de documentos del Archivo Germán Guzmán, el libro analiza el bandolerismo en Colombia durante la llamada Violencia tardía, aquel triste periodo de la historia nacional comprendido entre los años 1958 (inicio del Frente Nacional) y 1965 (muerte del Siete Colores). Se analizan las características sociológicas más sobresalientes de este fenómeno, su ubicación y concentración en la geografía nacional, el carácter de las cuadrillas, la participación en ellas de la mujer bandolera, la vida cotidiana en estas estructuras armadas de hombres rudos, el desafío que significaron para el Estado colombiano y cómo cientos de bandoleros, que integraban más de 120 bandas, murieron en los enfrentamientos con el Ejército y la Policía y la tristeza de muchos campesinos por esas muertes. Lo anterior se ejemplifica con la reconstrucción de las trayectorias vitales de los tres principales bandidos liberales: Sangre Negra, Desquite y Chispas. El libro se pregunta por las causas sociales y las subjetividades que explicarían el proceso mediante el cual un número muy grande de campesinos fueron arrastrados, por la fuerza de las circunstancias, a empuñar las armas para defender sus vidas y cómo se convirtieron en asesinos desalmados y las continuidades y discontinuidades con el conflicto actual que padece Colombia.
Cerebrospinal fluid shunt for normal pressure hydrocephalus patient exacerbates cord symptoms due to spinal tumor
Authors: Kikuchi Jin , Uchikado Hisaaki , Hattori Gohsuke , Nagase Satoshi , Nakamura Yukihiko , Miyagi Tomoya , Okura Akira , Morioka Motohiro
Published: August 2022

Background:

Normal-pressure hydrocephalus (NPH) and spinal intradural extramedullary benign tumors rarely exist together. Here, a 72-year-old female who presented with NPH symptoms (i.e., gait disturbance and dementia) newly developed symptoms of spinal cord compression attributed to a previously undiagnosed schwannoma.

Case Description:

A 72-year-old female was diagnosed with NPH without disproportionately enlarged subarachnoid space hydrocephalus. The lumbar puncture revealed an elevated cerebrospinal fluid (CSF) protein level of 0.141 g/dl, but with normal pressure. The patient’s NPH symptoms improved after lumbar-peritoneal shunt placement. However, a year later, she subacutely developed a progressive Brown-Sequard syndrome. On the cervical magnetic resonance (MR), an intradural extramedullary lesion was found at the C5-C6 level which at surgery, proved to be a schwannoma. A review of this patient and three others with NPH and intradural extramedullary benign tumors revealed that 4.3 months following CSF shunting for NPH, they developed rapidly progressive cord deficits, attributed to their benign spinal tumors.

Conclusion:

Before the placement of shunts for NPH, patients should undergo holospinal MR imaging studies to rule out attendant spinal intradural extramedullary tumors.

Photoinduced Halogen-Atom Transfer (XAT) by N-heterocyclic carbene boryl radicals for C(sp3)−C(sp3) bond formation
Authors: Wan Ting , Capaldo Luca , Ravelli Davide , Vitullo Walter , de Zwart Felix , de Bruin Bas , Noel Timothy
Published: August 2022

In the realm of radical chemistry, halogen-atom transfer (XAT) is emerging as a powerful activation strategy in synthetic endeavors to engage otherwise recalcitrant organic halides. Although toxic tin radicals have been in the spotlight as halo-gen abstractors for decades, the era of photocatalysis has brought to light more sustainable options. Herein, we present a comprehensive study on the use of ligated boryl radicals to enable C(sp3)−C(sp3) bond forming reactions via XAT from alkyl halides. Two strategies have been developed using either direct light activation with near UV or photoredox conditions with visible light; both pivoting on N-heterocyclic carbene (NHC) boryl radicals. The present XAT strategy is very mild and accommodates a broad scope of alkyl halides, including medicinally-relevant compounds and biologically-active molecules. The key role of NHC boryl radicals in the operative reaction mechanism has been elucidated through a combination of ex-perimental, spectroscopic and computational studies.
Convenient Confinement: Interplay of Solution Conditions and Graphene Oxide Film Structure on Rare Earth Separations
Authors: Carr Amanda J. , Lee Seung Eun , Kumal Raju R. , Bu Wei , Uysal Ahmet
Published: August 2022

Graphene oxide (GO) membranes are excellent candidates for a range of applications, including rare earth separations and radionuclide decontamination. Membrane performance varies widely under different conditions, as water and ion interactions with the membrane are strongly affected by small system changes. Feed solution pH is one critical factor, as pH, GO surface functionality, and ion speciation are interconnected parameters that cannot be controlled individually. Understanding nanoscale water and ion behavior near interfacial GO is critical for groundbreaking membrane advances, including improved selectivity and permeability. We experimentally examine the impact of solution conditions on water and lanthanide interactions with self-assembled GO films and connect these results to GO membrane performance. The investigation of the confined films at the air-water interface with a combination of surface-specific spectroscopy and X-ray scattering techniques allows us to understand water and ion behaviors separately. Sum frequency generation spectroscopy reveals a dramatic change in interfacial water organization because of graphene oxide film deprotonation. Interfacial X-ray fluorescence measurements show a 17x increase in adsorbed lanthanide to the GO film from subphase pH 3 to pH 9. Liquid surface X-ray reflectivity data show an additional 2.7 e- per Å2 for GO films at pH 9 versus pH 3 as well. These data are connected to GO membrane performance, which show increased selectivity and decreased flux for membranes filtering pH 9 solutions. We posit insoluble lanthanide hydroxides form at higher pHs. Take together, these results highlight the importance of interfacial experiments on model GO systems.
Theoretical Study on the Mechanism of Hydrogen Evolution Reaction Catalyzed by Platinum Subnanoclusters

The smallest subnanocluster models of platinum colloid (Ptn) are supposed to diffuse in aqueous media in order to examine their behaviors when they are subjected to electrocatalytic hydrogen evolution reaction under the zero overpotential condition at pH 0. The DFT approach allows us to clarify the natures of individual proton transfer (PT) and electron transfer (ET) processes together with the importance of relying on concerted proton-electron transfer (CPET) pathways to promote the majority of H* adsorption processes by the Ptn subnanoclusters. Although the CPET processes are closely correlated with the Volmer steps (Pt + H+ + e− --> Pt-H*) described so far in electrochemistry, our study for the first time points out the essential capability of the Ptn clusters to promote the multiple PT steps without the need to transfer any electrons, revealing the fundamentally high basicity of the naked Ptn clusters (pKa = 27-28 for Pt4, Pt5, and Pt6). The discrete cluster models adopted herein avoid the structural constraints forced by the standard slab models and enable us to discuss the drastic alterations in the geometric and electronic structures of the intermediates given by the consecutive promotion of multiple CPET steps. The weakening in the Pt-H* bond strength with the increasing number of CPET steps is well rationalized by carefully examining the changes in the ν(Pt-H*) vibrational frequencies, the hydricity, and the H2 desorption energy. The behaviors are also correlated with the underpotential and overpotential deposited hydrogen atoms (HUPD and HOPD) discussed in the electrochemical studies for many years.

Breast cancer is among the most prevalent type of cancer among women. Mastectomy is a common surgical option for breast cancer, which usually leads to significant functional impairment. Fatigue, anxiety and depression are reported by mastectomy patients. This study aims to investigate the effect of a multimodal exercise program on improving functional impairment, fatigue, anxiety and depression after mastectomy. A 40-year-old female presented with abnormal tissue growth, pain and nipple discharge at the right breast. She was diagnosed with invasive ductal carcinoma stage I and undertook six weeks of neoadjuvant chemotherapy followed by modified radical mastectomy (MRM). Postoperatively, patient had a functional impairment, fatigue, anxiety and depression. An eight-week multimodal exercise program comprising ROM exercises, strength and endurance training, breathing exercises and functional activities was given. DASH for assessing upper extremity functions, BFI for assessing the impact of fatigue on daily activities and HADS for assessing anxiety and depression. An eight-week multimodal exercise program effectively improves functional impairment, fatigue, anxiety and depression in mastectomy patients with rheumatoid arthritis.

The efficacy of self-supervised learning techniques in a variety of application fields has helped them become more popular recently. In this work, we give 3D proxy tasks for five various self-supervised learning approaches using these principles. By enabling neural network feature learning from unlabelled 3D images, we hope to minimise the cost of expert annotation. The techniques include Relative 3D Patch Location, 3D Exemplar Networks, 3D Rotation Prediction, 3D Jigsaw Puzzles, and 3D Contrastive Predictive Coding. Our findings show that pretraining models using our 3D tasks generates more rich semantic representations and enables completing downstream tasks more accurately and quickly compared to training the models from scratch and pretraining them on 2D slices.
A Three-Dimensional Case System Model for Programming Course
Authors: Zhang Jinghua
Published: August 2022

This research aims to construct a case resource library for programming course, which can be used for either teachers’ teaching or students’ learning. The cases cannot be simply piled up but rather require a systematic planning. The solution to this is to design a case system model. The outcome-based education (OBE) concept is adopted to guide the research, and a three-dimensional case system model matching the course objectives is designed. Under the guidance of the model, the case resource library construction is more planned. Cases based on the model can provide all-round support for the cultivation of students’ ability by gradually promoting knowledge and technology, frequently exercising one’s abilities, as well as expanding diverse and innovative problems.
Airlines Cost Control in China: An Overlooked Perspective
Authors: Wang Huiyun
Published: August 2022

With the deepening of economic globalization, the business environment has seen profound changes. The cost of aviation fuel has grown to represent a significant portion of air transportation costs for “energy-dependent” airlines. The cost of aviation fuel makes up a sizeable amount of Chinese airlines’ cost structure and is increasingly limiting their profitability. The question of how to control the cost of aviation fuel from various perspectives has garnered widespread attention. This paper puts forward an overlooked perspective – the procurement strategy. Firstly, it describes the necessity of aviation fuel cost control, and then analyzes specific cases of aviation fuel procurement cost control. Finally, it proposes several effective suggestions from the perspective of aviation fuel procurement, aiming to improve the refined management of Chinese airlines’ aviation fuel procurement.

Partimos da história da capoeira na cidade de São Paulo e da tiririca, uma capoeira jogada ao som do samba, cultura tipicamente paulista, para entender o discurso identitário criado sobre a capoeira pelos capoeiristas baianos que aqui chegaram. Além disso, pretendemos averiguar de que modo é factível aplicar o conceito de circularidade cultural à capoeira de São Paulo das primeiras décadas do século XX e à tiririca, bem como às propostas da Regional e da Angola paulistanas. É nossa intenção também indagar se e de que forma a Roda de Capoeira da Praça da República contribui para a ressignificação daidentidade dos capoeiristas migrantes nordestinos, que, ao vir para a cidade de São Paulo, passariam a ser fortemente discriminados.
Por uma política da vadiação: a capoeira “fazendo” cidades em Fortaleza

A capoeira e as dinâmicas da vida urbana, historicamente, travam um íntimo diálogo, implicando mútua (in)formação a partir de experiências localizadas em espaços públicos citadinos como portos, mercados e largos. Escusado dizer que esse diálogo com as ruas permanece vivo na atualidade, sobretudo em territórios das cidades que são considerados “periféricos”, de “margem” ou “precários” (AGIER, 2015). Assim, o presente artigo objetiva refletir sobre a capoeira enquanto produção da margem, considerando-a como uma “situação-limite” (AGIER, 2015) que enseja precipitações políticas, ações produzidas por coletivos de sujeitos que interpelam as dimensões de “ordenamento” e de “prescrição” dos mundos urbanos planejados a partir e para as “centralidades” e seus sujeitos; que criticam a sustentação de usos, sentidos e relações considerados hegemônicos, dominantes ou legítimos. Para tanto, mobilizando pesquisas etnográficas, os bairros Serrinha e Gentilândia (Fortaleza, Ceará, Brasil) são tomados como espaços privilegiados de reflexão.

The threaded rod without water stop plate is used to replace the original water stop bolt. The threaded rod is composed of a full-length threaded rod, a tapered screw sleeve and a nut. With the help of the threaded rod, the water seepage path of the wall is changed, the water seepage line is extended, and the water pressure is reduced, so as to achieve the water stop effect. Its implementation not only reduces the processing difficulty, but also can adjust the bolt buckle spacing according to the thickness of the outer wall of the basement, effectively strengthen the formwork, and reduce the risk of formwork expansion and explosion; It can be manually removed to reduce on-site hot work. It is a better choice for the basement wall formwork system.
