An Analysis of Critical Variables Affecting Working Capital in Infrastructure Projects
Authors: Kantianis D D , Liapis K J
Published: September 2023

The research aims at exploring the critical variables that affect public works contractors’ working capital in the delivery of infrastructure projects. Effective financial management has long been recognized as the ‘lifeblood’ of construction contractors, especially during economic periods of recession. The main reason for insolvency in the built environment is the lack of working capital to support contractors’ site operations. Therefore, it is vital to accurately predict the project working capital requirements at the pre-tender stage and closely monitor project cash-flow during the physical production process. The proposed methodology entails the development of a cash-flow/ working capital calculation process based on spreadsheet modelling and the Gantt chart for the derivation of project disbursements S-curves, revenue step function curves, and maximum/net cash-flow profiles. The model is implemented to a recently delivered typical infrastructure project – the construction of a new peripheral highway reinforced concrete bridge – and a sensitivity analysis is conducted to reach useful conclusions concerning the significance in infrastructure working capital of the following variables examined: the retention percentage, the ‘front-end rate loading’ by the contractor, and the premium advance incentive by the owner. The lowest maximum working capital requirement results from the provision of an advance mobilization payment by the owner to the contractor at project start-up and the selection of the latest start times site work execution program. The herein presented study is expected to assist both researchers and practitioners operating within the public construction sector in decision-making towards more effective financial management of infrastructure projects.

E-shopping Across EU – Why Some Individuals Refuse to Adopt It?
Authors: Božić L , Botrić V
Published: September 2023

Despite many advantages of e-commerce for both firms and buyers, it is still not equally adopted by customers in all European Union countries. According to Digital Scoreboard in countries such as United Kingdom and Denmark, nearly 90% of Internet users shop online. On the other hand, in Romania and Bulgaria, not even one-third of the Internet users buy goods and services online. Diffusion of e-shopping clearly has different pace across EU. In this article, we focus on individuals who refuse to purchase over Internet and aim to explore reasons for their behavior. To do so, we rely on Community Statistics on Information Society (CSIS) microdata for the year 2015. Individuals who report ordering and buying over the Internet more than one year ago and those who never engaged in online shopping were asked about reasons for not buying online. Potential reasons include lack of skills, privacy and security concerns, delivery concerns and problems, not having payment cards as well as habit, loyalty and preference of shopping in stores. The focus of this article is on comparison of reasons for not shopping online of individuals in EU countries that lead in adoption of e-shopping with laggard countries. We first analyze the prevalence of reasons for not buying online and compare countries in that respect. Among individuals who did not adopt e-shopping, there are those who have tried it at one point in time and did not continue to use it frequently and those who actually never engaged in buying over Internet. Both have certain reasons and constrains that prevent them from adopting this form of shopping. The analysis is followed by identification of reasons that significantly affect probability of trying online shopping, if not adopting it fully. It can be assumed that gaining true experience might contribute to increase in adoption of e-shopping among individuals. This is even more important for countries that still lag behind not just in buying online but in overall digital performance.

Authors: Sharma Ashwani Kumar , Sidhu Sukhdeep Singh , Jena Biswa Ranjan
Published: September 2023

Background- Evaluation of transtracheal wash (TTW) has been proved beneficial in the diagnosis and understanding the pathology of lower respiratory tract infection in species like equines and dogs. However, its diagnostic potential in buffaloes has not been explored much. This study elucidated the cytological and microbiological features of TTW in buffaloes. Methods- TTW was collected from 36 buffaloes (26 diseased and 10 healthy control) after adequately restraining and using baby feeding tube after giving a small stab incision at ventral neck region. After collection, TTW were subjected to cytological studies following staining with Leishman stain. TTW was also sent aseptically to laboratory for bacteriological culture. Results- The lower respiratory tract affections like aspiration pneumonia, suppurative pneumonia, fibrinopurulent pneumonia, chronic pneumonia and tuberculous pneumonia were diagnosed based on cytology of TTW in correlation with history and comprehensive clinical examination. The mean cell number (cells/HPF) in TTW of diseased buffaloes were significantly higher than control groups. In control groups, the predominant cells were alveolar macrophages followed by neutrophils, epithelial cells, lymphocytes and other cells which includes mast cells, fibroblasts and unidentified nucleated cells. Neutrophils were the predominant cells followed by macrophages in TTW of buffaloes diagnosed with suppurative, fibrinopurulent and aspiration pneumonia, whereas, alveolar macrophage were predominant in TTW of chronic pneumonia and tuberculous pneumonia affected animals. Four out of ten TTW samples from healthy animals were evidenced bacterial growth in which Staphylococcus spp. was the predominantly isolated bacteria. TTW samples from 20 out of 26 diseased buffaloes were found positive for bacterial culture from which a total of 30 bacterial isolates were obtained which include Staphylococcus aureus, Klebsiella pneumonia, Pasteurella multocida, Streptococcus spp., E. coli and Bacillus spp. Thus, TTW provides vital information about the ongoing pathogenesis in respiratory tract infection. It is suggested that, cytological and bacteriological culture of TTW samples should be carried out during the diagnosis and therapeutic intervention of respiratory tract infection in buffaloes.

Published: September 2023

Background: Pig farming is an important source of income and nutrition for rural farmers in Goa. Pig production is threatened by many infectious diseases. The present study reports a respiratory disease outbreak in a total of 200 pigs including adults and piglets with 40% mortality in a pig herd of Large white Yorkshire and crossbreds in South Goa during the winter period in January 2022. Method: The farm was visited and recorded clinical signs and post mortem findings and and samples were collected for bacterial isolation, PCR confirmation of bacterial and viral pathogens and histopathology. Result: The affected pigs showed high fever, reduced feed intake, staggering gate, huddling, difficulty in breathing, cough, and brown to greenish diarrhea followed by death within a span of 3 weeks. Major gross lesions were non-collapsed lungs with severe congestion and localized areas of consolidation, severe congestion of viscera, and enlargement, and presence of multifocal areas of necrosis in the liver. Histopathology of lungs focal or diffuse bronchointerstitial pneumonia and the lymphoid organs showed lymphoid depletion. Pasteruella multocida could be isolated from heart blood and tissues from 3 cases and PCR of the tissue DNA confirmed the presence of P. multocida and Porcine Circo Virus-2 (PCV-2) infection. The study confirms the presence of PCV-2 infection in pig herds in Goa for the first time. The acute mortality can be attributed to the co-infection of the herd with PCV-2 and P. multocida and sudden change in weather patterns with prevailing severe cold conditions during time of outbreak. Sequencing and Phylogenetic analysis of the PCV-2 ORF-2gene showed the PCV-2 virus from Goa is more related to isolates from southern Indian states.

Published: September 2023

Background: Tomato (Lycopersicon esculentum Mill) is a staple fruit vegetable, one of the most important vegetables worldwide. There is high demand for tomato planting materials (seeds) in Nigeria. Methods: Experiment was conducted at the Directorate of University Farms, Federal University of Agriculture, Abeokuta (FUNAAB), Nigeria (7°, 25'N, 3°25'E, 100 m above sea level) to examine growth, fruit characteristics as well as seed yield of tomato (Lycopersicon esculentum Mill), cultivar Roma vf in response to fertilizer treatments. Fertilizer types used were, NPK 15:15:15 (300 kg/ha), Poultry manure (10 t/ha), combination of N. P. K 15:15:15 (150 kg/ha) + Poultry manure (5 t/ha) and a control. Treatments were laid out in randomized complete block design with three replicates. Data were taken on number of leaves, plant height, leaf area, number of branches, number of flowers, number of fruits, fruit length, fruit width, fruit yield, unit fruit weight, number and weight of seeds per fruit. Fruit characteristics were correlated with seed yield to determine the relationship between them. Data were subjected to analysis of variance (ANOVA) and means were separated with least significant difference (LSD 0.05). Result: Tomato fruits from plots that received a combination of N. P. K 15:15:15 (150 kg/ha) and Poultry manure had higher fruit yield (5 t/ha) and by inference higher number of seeds, compared with the control. Correlation of fruit weight with number of seeds showed that the higher the fruit weight, the higher the number of seeds per fruit. Fruit length had positive correlation with plant height and fruit diameter. Number of leaves determines fruit weight which invariably determines number and weight of seeds. High number of leaves resulted in low seed weight

Published: September 2023

Background: Being a vital source of high-quality dietary protein, chickpea is an unavoidable legume. The present investigation was performed to study the applicability of the microsatellite markers linked with drought tolerance in Indian chickpea genotypes collected from different genetic background. Methods: In Rabi 2021-22, forty chickpea genotypes including national check for drought tolerance, elite cultivars, released varieties and advanced breeding lines were screened employing forty microsatellite markers linked with drought tolerance associated traits. Result: Among forty drought tolerance related microsatellite markers, twenty-six were found to be polymorphic and produced a total of 66 alleles, with a mean of 2.5 alleles per locus. Model-based population structure analysis clearly distinguished the drought tolerant genotypes including ICC4958, JG74, JAKI9218, JG16, JG6, JG14 and JG11. The principle coordinate analysis (PCoA) and analysis of molecular variance (AMOVA) further confirmed these results. Findings of the present investigation would have a greater potential for further utilization in breeding of drought specific chickpea cultivar(s).

Una lectura fenomenológico-hermenéutica de la interpretación. El caso del conocimiento de la historia
Authors: Gilardi Pilar
Published: September 2023

El artículo propone una lectura fenomenológico-hermenéutica del fenómeno interpretativo a partir del pensamiento de Martin Heidegger. En concreto, de aquel que va de las primeras lecciones (1920-1923), hasta Ser y tiempo (1927). Desde este horizonte de comprensión, la interpretación no debe entenderse como mero sinónimo de opinión subjetiva, sino como fenómeno ontológico y estructural.

Do «espanto» da terra ao conhecimento do Brasil
Authors: Marques Maria Alegria Fernandes
Published: September 2023

Partindo-se do conhecimento da experiência dos portugueses nos contactos com povos não europeus por ocasião da chegada a terras do Atlântico Sul, pretende-se analisar o espanto que a nova terra e os seus habitantes provocaram nos portugueses, bem assim a curiosidade que a maravilha da terra lhes causou e que os levou a adentrá-la e a conhe cê-la. Com a fixação dos portugueses, iniciou-se uma corrente de busca de Portugal, sobretudo o saber da sua universidade, originando uma plêiade de cientistas brasileiros, que deixaram obra notável em diversos ramos do saber, particularmente através das célebres viagens filosóficas do século XVIII. Donde, a existência de colecções literárias e científicas na Universidade de Coimbra.
Yvette Duval and the Late Antique North Africa

Published: September 2023

Yvette Duval’s publications offer diverse and contrasting aspects about the dynamism of late-antique North Africa. I have underlined the extent to which they were able to exert a considerable influence in recent historiography. The ideas defended in her various articles and books cannot leave anyone indifferent. Discussing them, drawing up a critical assessment, seeing them questioned, does not mean doing an iconoclast’s work. On the contrary, it is the best tribute that can be paid to a wo man who defended the idea of a multicolored Late Antiquity, far from the stereotypes resulting from the Aufklärung of crisis an decadence.
Autoria e responsabilidade jurídica na imprensa brasileira do século XIX
Authors: Godoi Rodrigo Camargo de
Published: September 2023

Partindo do conceito de “apropriação penal da autoria”, conforme descrito e analisado por Michel Foucault e Roger Chartier em seus estudos sobre a emergência da função autoral e do autor na Era Moderna, este artigo se debruça sobre o problema da autoria e da responsabilidade jurídica na imprensa brasileira do século XIX. Na medida em que o anonimato nos jornais era franqueado pelas leis de imprensa do Império, a responsabilidade jurídica de textos considerados injuriosos e sediciosos impunha-se como questão incontornável para juristas, jornalistas, redatores e impressores. Deste modo, com o objetivo de contribuir com a história jurídica da cultura impressa no Brasil, o artigo também investiga como a violência e as reformas no judiciário refletiram sobre as práticas da autoria na imprensa, com destaque para a atuação do “testa de ferro”. Ao ser contratado para assumir a responsabilidade legal de textos publicados em jornais e periódicos, esta personagem converteu-se em peça fundamental para o funcionamento da imprensa brasileira no oitocentos.
Machado de Assis
Authors: Azevedo Silvia Maria
Published: September 2023

Noção recorrente na crítica literária brasileira do Oitocentos, o estilo esteve associado à correção gramatical, à figura do autor, à ideia de ornamento, expressão do bem escrever e do bem falar, de forte presença no púlpito e na tribuna. Muito embora reivindicasse sua importância na obra de todo escritor e mesmo na ciência, Machado de Assis vai se opor às concepções de estilo em uso no seu tempo, conforme deixou registrado em “A nova geração”, “O velho Senado” e “Teoria do medalhão”. Tendo em vista o corpus selecionado da obra machadiana, o artigo tem como proposta a seguinte discussão: é na escrita machadiana, em se valendo tanto da retórica, em particular a écfrase, quanto da ironia e da paródia, que Machado de Assis não apenas põe em xeque uma noção tornada clichê, como constrói estilo próprio, sua identidade autoral, distanciada do patronímico.
Sexual Violence in the Islamic Law Perspective: Aceh Islamic Law and Local Wisdom Approach
Authors: Danial Danial , Yoesoef Yoesrizal M. , M Nur Sari Dewi.
Published: September 2023

The study aims to examine the integration of religious values, Aceh culture, and global issues, which form the Sexual Violence Crime Law (UU-TPKS). This article is a qualitative study with a descriptive approach where the primary data were obtained through interview and group discussion. The study used relevant sources from books, journals, and articles related to the chosen theme as the secondary data. This study shows that integration of religious values into the Sexual Violence Crime Law (UU-TPKS) is necessary because Indonesian law must be based on the Pancasila philosophy as a result of the translation into Islamic values. It further shows that religious, cultural, and global values embodied in that law are the values of tauhid, justice, freedom, kindness, cooperation, equality, and tolerance. The state must measurably implement all values and derive them into laws and regulations. The study also reveals that such an integration reflects the integration of religious principle and values and local wisdom described in various meanings and symbols.

Published: September 2023

The objective of this study is to assess the efficacy of a comprehensive strategy for developing the professional abilities of social educators. Additionally, it seeks to identify the problems encountered by high schools in this regard and examine the process of cultivating professional competencies. The research comprised a sample of 253 individuals from L. Gumilyov Eurasian National University, located in Astana, Kazakhsta. The study compares the diagnostic results on a quantitative and qualitative level. The assessment standards of Fisher and the descriptive statistics were acquired. The study's data was gathered by requesting questions from teachers and students, testing, interviews, and evaluations from experts who fit this profile. The findings indicated that future social educators will have problems with their lack of high-level professional competence.  Additionally, the majority of employers have requirements that are related to how well students develop their skills as well as their motivation to engage in extracurricular activities, work on themselves, and engage in future professional endeavors. The study revealed that employing an integrated strategy for the training of prospective social teachers yielded the most significant impact on the development of their professional abilities. The study's findings can be used to improve vocational training for social educators.

Decreasing the urban carbon footprint with woody biomass biochar in the united states of america
Authors: Franco Carlos Rodriguez , Page-Dumroese Deborah S.
Published: September 2023

Urban centers are places with a high human population concentration, and they can pose social, economic, and environmental challenges. These challenges are accentuated by the increased use of available open space for housing and industrial expansion, leading to elevated energy consumption, increased pollution, higher carbon emissions, and, consequently, adverse effects on human health. Many of these issues also contribute to the acceleration of climate change. There are several ways to decrease these problems through the expansion of greenspaces that conserve biodiversity, decrease air pollution, improve human well-being, and reduce human health risks, while also allowing people to enjoy the benefits of ecosystem services. This review is aimed at professionals who can manage urban landscapes - including adjacent forests, urban parks, tree beds, or home gardens that produce biomass that, together with other non-chemically treated wood waste, could be used to produce and use biochar. Biochar-amended soils provide the benefits of increased carbon sequestration, water retention, and soil productivity and can also decrease stormwater runoff. In addition, a small number of cities around the world have adopted biochar as a nature-based solution to decrease the impacts of climate change. We point out the opportunities and benefits of converting urban wood waste into biochar, how cities can improve their green environments, and, at the same time, produce energy from waste that would otherwise end in landfills with no use or value. Finally, based on previous assessments of wood waste in the United States of America, we estimate the biochar potential to sequester CO2.
Visiones de un futuro urbano posible: escenarios para la ciudad de las tres ecologías = Visions of a possible urban future: Scenarios for the city of the three ecologies
Authors: Verdaguer Viana-Cárdenas Carlos
Published: September 2023

ResumenEl objetivo principal de la presente tesis es aportar elementos para la consolidación de una nueva cultura del territorio y para una nueva teoría y una nueva práctica de la planificación urbana y territorial que, a partir de los conceptos que se articulan en torno al denominado paradigma ecológico, contribuya a complementar y reorientar el abanico de instrumentos desarrollados por la disciplina urbanística. Como marco de referencia se ha recurrido a la perspectiva epistemológica desarrollada por Félix Guattari en su obra Las tres ecologías (1989), a partir de las tres dimensiones ecológicas básicas: la ambiental, la social y la mental. Este armazón tridimensional ha permitido abordar de forma sistemática una realidad rizomática, en la que se pueden identificar muchas más dimensiones interconectadas.AbstractThe main objective of this thesis is to provide elements for the consolidation of a new culture of the territory and for a new theory practice of urban and territorial planning, based on the so-called paradigm ecological and the battery of concepts arisen around it, so contributing to complement and redirect the range of instruments developed by the urban discipline since its formation. The epistemological perspective developed by the philosopher and psychoanalyst Félix Guattari in his work The Three Ecologies (1989) has been used as a framework of reference, built around what he defines as the three basic ecological dimensions: environmental, social, and mental. This three-dimensional framework has allowed a systematic approach to a rhizomatic reality, in which many more interconnected dimensions can be identified.
Morphometric characteristics of the bovine bones from the excavations of the Bronze Age site of Gonur-depe
Authors: Sataev R.M. , Sataeva L.V.
Published: September 2023

Gonur-depe is a Bronze-Age archaeological site in Turkmenistan, the presumable center of Ancient Margi-ana (the Bactrian-Margiana archaeological complex), located in the South-Eastern Karakum. The proto-urban center was functioning from 2500 to 1500 BC. The basis of the economy of the ancient population was mixed farming, including irrigated agriculture and livestock. Cattle was used as the source of meat, milk, skins, as well as draft animals and in rituals. In terms of the number of bones from the excavations, cattle is inferior to small cattle. However, in terms of the meat production, the contributions of bovine cattle and small cattle to the diet of the inhabitants of Gonur-depe were commensurable. Bones of older individuals predominate amongst the animals slaughtered for meat. Bones of bovine cattle are found in all excavation trenches of the site in garbage layers and ritual structures. At the same time, information on the morphological features of the cattle has been extremely limited until recently. Therefore, this study was aimed at the analysis of the morphometric characteristics of the skeletal remains of cattle from the excavations of Gonur. These data give an idea of the size of the cattle bred by the ancient population. Complete skeletons are of particular interest for the morphological study. We have studied the skeletons from burial No. 3895 of Northern Gonur, tomb No. 12 of Gonur-21, and remains of a dismembered carcass from burial No. 3890. The first skeleton belongs to an adult bull, the second to a calf, and the dismem-bered carcass belongs to a young cow. The size of the bull, measured by the skeleton, is quite large. It reached a height of at least 136 cm. Comparison of the measurements of disparate cattle bones from Gonur and other sites of the Bronze Age shows that they are on average larger than those of cattle of the Late Bronze Age of Eastern Europe, close in size to the bones of cattle from the Trans-Urals, and slightly smaller than the Eneolithic cattle of Southern Turkmenistan. The sizes of the metapodia, talus bones and first phalanges were used to calculate the height at the withers by disparate bones. The average height at the withers of the cattle from Gonur, recon-structed on the basis of the measurements of the skeletons and scattered bones, was at least 120 cm for cows, at least 130 cm for bulls, and 132 cm or more for oxen. Therefore, the size of the cattle bred by the inhabitants of Gonur in arid conditions was not smaller, and in some cases even larger than that of cattle of some other cultures of the Late Bronze Age and differed insignificantly from the Eneolithic cattle of Southern Turkmenistan.
A Кipchak burial of the Menovnoe VII burial ground in the Upper Irtysh River Basin
Authors: Tkachev A.A. , Tkachev Al.Al.
Published: September 2023

In this paper, the materials of one of the burial mounds of the Early Kipchak cemetery of Menovnoe VII dated to the turn of the 1st–2nd mil. AD are introduced into the scientific discourse. It was the time of transition in the steppes of the Upper Irtysh River Basin of the hegemony from the Kimaks to Kipchaks; it is scantily addressed in the scientific literature, although, according to the written sources, it was specifically in the steppes of Eastern Kazakhstan where the Kipchaks started dominating; the vector of power changed, and the genesis of the Kipchak Khanate took place. There was the beginning of the Kipchak migration into the bordering regions of Kazakhstan, Central Asia, steppes of the Volga region, and Northern Circumpontic region, where they became known in his-tory as Polovtsy, according to the Russian chronicles, or Cumans in the Byzantine sources. Materials from the burial mounds of the Menovnoe VII cemetery are indicative of the earliest period of the emergence of the Kipchak traditions, which further developed already outside the region of their formation.
An adaptive power management tool for sizing a PV-battery-hydrogen off-grid electrical energy system
Authors: Pace Loris , Zouaghi Ayyoub , Beley Matthieu , Haddour Naoufel
Published: September 2023

Off-grid electrical energy systems based on renewable energy sources (RESs) have become increasingly popular for their ability to generate low-carbon electricity in remote areas without access to traditional power grids. These systems rely on the effective management of RESs and storage solutions. Designing and sizing these systems can be a complex task, requiring careful consideration of various parameters such as energy demand, solar irradiance, storage capacity of batteries and State of Charge, power management of fuel cells, and hydrogen production and storage. This study presents an adaptive power management tool that facilitates the sizing of energy equipment for standalone low-carbon microgrids. The proposed simulation tool, implemented in Matlab/Simulink, is based on mathematical models for each energy unit and incorporates a specific power management strategy to determine the optimal size of each component in the system. The effectiveness of the tool is illustrated through a case study involving a PV-battery-hydrogen energy system designed to supply electricity to a standalone district. Results show that the developed tool can be a valuable aid for system designers and planners for creating sustainable and reliable off-grid electrical energy systems, as well as for educational and learning activities.
Piston Error Measurement for Segmented Telescope Based on a Hybrid Artificial Neural Network
Authors: Yue Dan , Song Pengcheng , Wang Congshuai , Chuai Yahui
Published: September 2023

Aimed for the difficulty and complexity of detecting the piston error for segmented telescope, this paper proposed a new piston error measurement method based on a hybrid artificial neural net-work. Firstly, we use Resnet network to learn the mapping relationship between the focal plane degradation image and the signs of the piston error. Then, based on the established theoretical re-lationship between modulation transfer function and the piston error, BP neural network is used here to learn the mapping relationship between the MTF and the absolute value of the piston error. After the training of the hybrid network is completed, a wide-range and high-precision detection of the piston error of the sub-mirrors can be achieved using the combined output of the two net-works only a focal plane image of a point source with broadband illumination is used as input. The detection range can reach the whole coherent length of the input broadband light, and the detec-tion accuracy can reach 10nm. The method proposed in this paper has the advantages of high de-tection accuracy, wide detection range, low hardware cost, small network scale and low training difficult.

How people recognize linguistic and emotional prosody in different listening conditions is essential for understanding the complex interplay between social context, cognition, and communication. The perception of both lexical tones and emotional prosody depends on prosodic features including pitch, intensity, duration, and voice quality. However, it is unclear which aspect of prosody is perceptually more salient and resistant to noise. This study aimed to investigate the relative perceptual robustness of emotional prosody and lexical tone recognition in quiet and in the presence of multi-talker babble noise. Forty young adults with normal hearing listened to monosyllables either with or without background babble noise and completed two identification tasks, one for emotion recognition and the other for lexical tone recognition. Compared with emotional prosody, lexical tones were more perceptually salient in multi-talker babble noise. Native Mandarin Chinese participants identified lexical tones more accurately and quickly than vocal emotions at the same signal-to-noise ratio. Lexical tone perception is also more robust against babble speech noise degradation than emotional prosody perception for native Mandarin Chinese listeners. Acoustic and cognitive dissimilarities between linguistic prosody and emotional prosody may have led to the phenomenon, which calls for further explorations into the underlying psychobiological and neurophysiological mechanisms.
Advancements in Exploiting Sporosarcina Pasteurii as Sustainable Construction Material: A Review
Authors: Khoshtinat Shiva
Published: September 2023

With the development of bioinspired green solutions for sustainable construction over the past two decades, bio-cementation, which exploits the naturally occurring phenomenon of calcium carbonate precipitation in different environments, has drawn a lot of attention in both building construction and soil stabilization. Various types of microorganisms, along with specific enzymes derived from these microorganisms, have been utilized to harness the benefits of bio-cementation. Different application methods for incorporating this mechanism into the production process of the construction material, as well as a variety of experimental techniques for characterizing the outcomes of bio-cementation, have been developed and tested. Despite the success of bio-cementation as a sustainable method to construction has been demonstrated in a significant body of literature at the laboratory scale, the expansion of this strategy to construction sites and field application remains a pending subject. The issue may be attributed to two primary challenges. Firstly, the complexity of the bio-cementation phenomenon is influenced by a variety of factors. Secondly, the extensive body of literature examines various types of microorganisms under different conditions, leading to a wide range of outcomes. Hence, this study aims to examine the recent advancements in utilizing the most commonly employed microorganism, Sporosarcina Pasteurii, to emphasize the significance of influential factors identified in the literature, discuss the findings that have been brought to light, and outline future research directions toward scaling up the process.

Published: September 2023

This paper presents a comprehensive evaluation of metal foam employment within polymer electrolyte fuel cells (PEFCs) and compares it with conventional serpentine channels from both experiment viewpoints and computational fluid dynamics simulation. The experiments are designed to study the effects of material, area density, compression ratio, and final thickness of metal foam. Additionally, the influence of housing plate material and relative humidity (RH) is also tested for the first time. The results reveal that at RH=75-100%, the best distributor design is nickel foam with a compression ratio of 70%, a final thickness of 0.5mm, and SS-304 housing plate, which delivers 3110 mA cm-2 as limiting current density that is scarce in the literature. The PEFC with this foam distributor shows a 10% improvement in maximum power density and 45% in limiting current density compared to the serpentine channel case. While at RH=30%, the same foam flow field with a final thickness of 1mm is a superior option. The experiments also indicate that maximum power density increases by 23% as the compression ratio rises from 0 to 70%, while reducing final thickness from 1 to 0.5 mm causes a 19% enhancement in cell performance. Simulation results reveal that metal foam is more successful in evenly reactant distribution so that the average oxygen mass fraction at the cathode catalyst layer is increased by 38% in the metal foam case compared to the serpentine channel.

Authors: Rafi Shakil
Published: September 2023

It is well known that the size of initial loans approved by private lending agencies (banks, credit unions etc.) corresponds with the median income of the location of the individual, it also corresponds with gender. We wanted to show if it was the case with the PPP. We use standard machine learning techniques such as Lasso and found statistically significant association between gender of business owner and size of initial loan approvals for the State of Arkansas, and Least Squares Regression and Decision Tree regression to find a somewhat tenuous relationship between median income and initial loan approval amount and finally a strong association with the size of business. This has important applications for the equity of access to credit for marginalized peoples.

Authors: Liu Fengcun , Li Shumei
Published: September 2023

Transformative learning is an emerging and unique learning theory for adults. Foreign adult education scholars, represented by Mezirow, have produced significant research results in this field. However, research in this area in China is relatively lacking. This paper interprets the personal story of an English teacher through six stages and combines transformative learning theory to position the roles of adult learners in transformative learning. The author believes that adult learners today must take on six missions and play the roles of discerners, reflectors, communicators, integrators, aspirers, and resilient individuals in the transformative learning process.

Published: September 2023

In light of advancing technology, the conventional clock network architecture has become inadequate for addressing the intricacies inherent in modern System-on-Chip (SoC) designs. While clock mesh topology offers resilience against On-Chip Variation (OCV) fluctuations, it still necessitates manual intervention. Therefore, substantial scope exists for methodological enhancements and the refinement of rapid analytical techniques. This paper introduces a novel clock mesh synthesis approach, underpinned by dynamic programming algorithms, that guarantees latency constraints. Our experimental findings demonstrate that our algorithm achieves an additional 26.6% reduction in power consumption compared to the baseline methodology. Furthermore, it substantially reduces runtime by an average of 78.0% when contrasted with traditional simulation methods. These results highlight the potential of our methodology for enhancing the efficiency and power management of clock mesh.

Published: September 2023

The flow around thick airfoils at low Reynolds numbers and the possibility of using energy methods to control flowfield, increase lift and reduce drag are considered. For calculations, a series of propulsion airfoils is used, obtained by a combination of solving the inverse problem of aerodynamics and stochastic methods of global optimization. The calculations take into account the transition from the laminar flow regime to the turbulent one, which has a significant effect on the lift and airfoil drag. The applicability of various turbulence models for airfoil modelling at low Reynolds numbers is discussed. The results of numerical simulation make it possible to determine the dependence of the lift coefficient on the angle of attack and the optimal flow rate of air taken from the airfoil surface for each angle of attack. The results of numerical simulation are compared with the data of a physical experiment, and conclusions are drawn about the accuracy of various turbulence models.

Online and offline shopping trip have different impacts on various aspects of urban life, such as e-commerce, transportation systems, and sustainability. Therefore, it is important to evaluate the factors that influence their choices. We use a hybrid machine learning model that combines a gray wolf optimization algorithm and a deep convolutional neural network to estimate shopping trip based on a survey of 1,000 active e-commerce users who made successful orders in both online and offline services in the last 20 days of 2021 in areas 2 and 5 of Tehran. The gray wolf optimization algorithm performs feature selection and hyperparameter tuning for the deep convolutional neural network, which is a powerful deep learning model for image recognition and classification. The results show that our model achieves an accuracy of 97.81% with an MSE of 0.325 by selecting seven out of ten features. The most important features are delivery cost, delivery time, product price, car ownership. In addition, comparing the performance of the proposed method with other methods showed that the proposed algorithm with an accuracy of 97.81%, the accuracies of the single deep learning model, MLP neural network, decision tree, and KNN models were 95.63%, 90.0%, 86.49%, and 80.16%, respectively.
