Special Issue on Fatigue, Performance, and Damage Assessments of Concrete

Field: Engineering (Physical Sciences)

This Special Issue covers the latest research on fatigue, performance, and damage assessments of concrete. Concrete fatigue is known as a phenomenon characterized by the repetition of loads. The fatigue-based performance of concrete may be affected by a combination of diverse loads, mechanical strength properties, and environmental changes. These factors eventually lead to poor concrete performance. In this Special Issue, nine papers were accepted, divided into three subgroups: two papers on fatigue, two papers on performance, and five papers on damage assessment. Unlike articles published in past Special Issues, our Special Issue contains papers that address concrete performance in concrete pavement applications. In particular, six of the articles contained in this issue concentrate on pavement performance and damage assessments, especially in terms of the Pavement Condition Index. Together with a brief introduction, the keywords, research significance and potential impacts of each article are summarized in this Editorial.
Effect of the Reversed L-Shaped Osteotomy on the Round Sign: Not All Hallux Valgus Deformities May Need Proximal Derotation to Correct the Radiographic Appearance of Metatarsal Pronation

Field: Medicine (Health Sciences)

Background Metatarsal pronation has been claimed to be a risk factor for hallux valgus recurrence. A rounded shape of the lateral aspect of the first metatarsal head has been identified as a sign of persistent metatarsal pronation after hallux valgus correction. This study investigated the derotational effect of a reversed L-shaped (ReveL) osteotomy combined with a lateral release to correct metatarsal pronation. The primary hypothesis was that most cases showing a positive round sign are corrected by rebalancing the metatarsal-sesamoid complex. We further assumed that the inability to correct the round sign might be a risk factor for hallux valgus recurrence. Methods We retrospectively evaluated 266 cases treated with a ReveL osteotomy for hallux valgus deformity. The radiologic measurements were performed on weightbearing foot radiographs preoperatively, at an early follow-up (median, 6.2 weeks), and the most recent follow-up (median, 13 months). Univariate and multivariate logistic regression analyses identified risk factors for hallux valgus recurrence (hallux valgus angle [HVA] ≥ 20 degrees). Results A preoperative positive radiographic round sign was present in 40.2% of the cases, of which 58.9% turned negative after the ReveL osteotomy (P < .001). Hallux valgus recurred in 8.6%. Risk factors for recurrence were a preoperative HVA >30 degrees (odds ratio [OR] = 5.3, P < .001), metatarsus adductus (OR = 4.0, P = .004), preoperative positive round sign (OR = 3.3, P = .02), postoperative HVA >15 degrees (OR = 74.9; P < .001), and postoperative positive round sign (OR = 5.3, P = .008). Cases with a positive round sign at the most recent follow-up had a significantly higher recurrence rate than those with a negative round sign (22.7% vs 5.9%, P < .001). Conclusion The ReveL osteotomy corrected a positive round sign in 58.9%, suggesting that not all hallux valgus deformities may need proximal derotation to negate the radiographic appearance of the round sign. A positive round sign was found to be an independent risk factor for hallux valgus recurrence. Further 3-dimensional analyses are necessary to better understand the effects and limitations of distal translational osteotomies to correct metatarsal pronation.

Performance Evaluation and Comparison of Two Cascaded Configurations of PV Generators-Five Levels Inverter for a Stand-Alone Application in South Algeria

Field: Energy (Physical Sciences)

In this paper two configurations of solar photovoltaic energy conversion using the NPC five levels inverter for stand-alone application in south Algeria are proposed and their performances compared. The first cascade uses four separate PV sources and the second configuration use only one PV generator. In these two cases and without DC/DC converter introduced between PV source and inverter and to get a stable AC voltage, authors in propose a proportional regulator of inverter modulation index. The SVPWM technique is used in order to get the best voltage waveform. For the second configuration proposed, we introduce in the control loops another algorithm which uses the redundant vectors of space vector diagram of inverter to stabilise the DC bus voltages. A real data of temperature and solar irradiation obtained by radiometric station in Ghardaïa city in south Algeria are used to test the performance of proposed controls. The simulation results show that the inverter output voltage is stable for the two configurations proposed despite the variation of solar irradiation, temperature and load. Also, the THD obtained is in the limits of international standards. Then, the PV cascade with separate PV sources is the best solution, seeing that we do not need to use another algorithm in the control loops.
Field Washing Efficiency in Removal of Macroinvertebrates from Aquatic Vegetation Mats

Field: Environmental Science (Physical Sciences)

ABSTRACT A new field washing technique for removal of invertebrates from aquatic vegetation was investigated. This technique, which involved field washing samples in alchohol (ETOH), was developed and tested with aquatic vegetation samples from two undisturbed lotic systems in Southern Nevada. Results indicated that approximately 60% of the animals were removed from watercress and algal mat samples by vigorous water washing in a bucket. Field washing of algal and watercress samples using ETOH removed an additional 20–40% of the total macroinvertebrates, with ETOH wash efficiency being higher in the watercress samples. Generally, tightly clinging organisms such as hydroptilid caddisfly pupae or case building midges were the only invertebrates not effectively removed from aquatic vegetation samples by a cambination of alchohol and water-washing in the field.

Making History, Creating Gender: Some Methodological and Interpretive Questions in the Writing of Oyo Oral Traditions

Field: Arts and Humanities (Social Sciences)

Of all the things that were produced in Africa during the colonial period—cash crops, states, and tribes, to name a few—history and tradition are the least acknowledged as products of the colonial situation. This does not mean that Africans did not have history before the white man came. Rather, I am making distinctions among the following: firstly, history as lived experience; secondly, history as a record of lived experience which is coded in the oral traditions; and finally, the recently constituted written history. This last category is very much tied up with European engagements with Africa and the introduction of “history writing” as a discipline and as profession. But even then, it is important to acknowledge the fact that African history, including oral traditions, were recorded as a result of the European assault. This underscores the fact that ideological interests were at work in the making of African history, as is true of all history. As such, tradition is constantly being reinvented to reflect these interests. A. I. Asiwaju, for example, in a paper examining the political motivations and manipulations of oral tradition in the constitution of Obaship in different parts of Yorubaland during the colonial period writes: “in the era of European rule, particularly British rule, when government often based most of its decisions over local claims upon the evidence of traditional history, a good proportion of the data tended to be manipulated deliberately.” This process of manipulation produced examples of what he wittily refers to as “ nouveaux rois of Yorubaland.”

Cyanobacteria: Model Microorganisms and Beyond

Field: Immunology and Microbiology (Life Sciences)

In this review, the general background is provided on cyanobacteria, including morphology, cell membrane structure, and their photosynthesis pathway. The presence of cyanobacteria in nature, and their industrial applications are discussed, and their production of secondary metabolites are explained. Biofilm formation, as a common feature of microorganisms, is detailed and the role of cell diffusion in bacterial colonization is described. Then, the discussion is narrowed down to cyanobacterium Synechocystis, as a lab model microorganism. In this relation, the morphology of Synechocystis is discussed and its different elements are detailed. Type IV pili, the complex multi-protein apparatus for motility and cell-cell adhesion in Synechocystis is described and the underlying function of its different elements is detailed. The phototaxis behavior of the cells, in response to homogenous or directional illumination, is reported and its relation to the run and tumble statistics of the cells is emphasized. In Synechocystis suspensions, there may exist a reciprocal interaction between the cell and the carrying fluid. The effects of shear flow on the growth, doubling per day, biomass production, pigments, and lipid production of Synechocystis are reported. Reciprocally, the effects of Synechocystis presence and its motility on the rheological properties of cell suspensions are addressed. This review only takes up the general grounds of cyanobacteria and does not get into the detailed biological aspects per se. Thus, it is substantially more comprehensive in that sense than other reviews that have been published in the last two decades. It is also written not only for the researchers in the field, but for those in physics and engineering, who may find it interesting, useful, and related to their own research.
Perceived Hearing Status and Attitudes Toward Noise in Young Adults

Field: Health Professions (Health Sciences)

Purpose To estimate the prevalence of perceived hearing loss, tinnitus, and temporary threshold shift (TTS) in community college students and to see whether those students' attitudes toward noise affected their perception of their own possible hearing loss, tinnitus, and TTS. Method Young adults ( N = 245; age 18–27) completed 3 questionnaires: the Hearing Symptom Description, Youth Attitude to Noise Scale, and Adolescents' Habits and Hearing Protection Use. Results Perceived TTS and pain associated with loud noise were the most common hearing related factors, followed by perceived tinnitus and hearing loss. The students' attitudes toward noise in their daily environment showed the most negative response, whereas attitudes toward noise and concentration indicated a more positive, or less harmful, response. Chi-square analysis indicated a significant correlation between perceived hearing loss and respondents' overall attitudes toward noise exposure. Hearing protection use was limited for all participants, with the majority reporting never having used hearing protection. Conclusion Approximately 6% of respondents reported perceived hearing loss, and 13.5% reported prolonged tinnitus. In general, participants had neutral attitudes toward noise. Over 20% of participants reported ear pain, tinnitus, and/or TTS after noise exposure at least sometimes. Coincidentally, few participants reported consistent use of hearing protection.
Non‐parametric Productivity Analysis with Undesirable Outputs: An Application to the Canadian Pulp and Paper Industry

Field: Decision Sciences (Social Sciences)

Abstract This article extends the Chavas‐Cox approach to non‐parametric analysis by incorporating undesirable outputs to provide a more complete representation of the production technology. Inner and outer non‐parametric technology bounds are constructed. The methods are illustrated with application to time series data for the Canadian pulp and paper industry. Conventional measures that ignore changes in pollutant outputs underestimate true productivity growth. Further, there is a large gap between estimates generated with reference to inner and outer bounds to the technology, suggesting that researchers need to be aware of the limitations of results derived from analyses relying only on DEA methods.
The role and function of PPARγ in bladder cancer

Field: Medicine (Health Sciences)

Peroxisome proliferator-activated receptor gamma (PPARγ), a member of the nuclear receptor superfamily, participates in multiple physiological and pathological processes. Extensive studies have revealed the relationship between PPARγ and various tumors. However, the expression and function of PPARγ in bladder cancer seem to be controversial. It has been demonstrated that PPARγ affects the occurrence and progression of bladder cancer by regulating proliferation, apoptosis, metastasis, and reactive oxygen species (ROS) and lipid metabolism, probably through PPARγ-SIRT1 feedback loops, the PI3K-Akt signaling pathway, and the WNT/β-catenin signaling pathway. Considering the frequent relapses after chemotherapy, some researchers have focused on the relationship between PPARγ and chemotherapy sensitivity in bladder cancer. Moreover, the feasibility of PPARγ ligands as potential therapeutic targets for bladder cancer has been uncovered. Taken together, this review summarizes the relevant literature and our findings to explore the complicated role and function of PPARγ in bladder cancer.

Biological Characteristics for Assessing Low Phosphorus Intake in Finishing Swine

Field: Agricultural and Biological Sciences (Life Sciences)

Three replicates of a randomized complete-block design in a 3 x 3 factorial arrangement of treatments involving 141 pigs were conducted to evaluate the effect of low P intake on various response criteria in swine from 65 to 95 kg body weight. Total dietary P levels of .09, .21 and .31% were each fed in a Ca:P ratio of 1.1, 1.5:1 or 2:1 for a 35-d experimental period. The basal diet was formulated using corn starch, dextrin and a soy protein concentrate with monosodium phosphate and limestone supplying desired treatment levels of Ca and P. Blood and bones were collected for mineral analysis. Gain and feed performance responses were not affected by Ca:P ration or dietary P level for the 35-d period. Serum inorganic P concentrations declined as Ca:P ratio increased, but increased as dietary P increased. Serum alkaline phosphatase activity increased with higher Ca:P ratios, and decreased as dietary P level increased. Percent bone ash was not influenced by Ca:P ratio, but increased as dietary P level increased. Bone-bending moment was influenced by Ca:P ratio, and increased linearly as dietary P increased. Dietary P level resulted in a linear increase in total bone and its ash component weight, and in the accretion of the ash and organic matrix component. These data suggest that between 65 to 95 kg body weight, percent bone ash was affected by dietary P level, while bone-bending moment, bone component weights, their accretion, both dietary p level and Ca:P ratio.
Circuit quantization in Hamiltonian framework: a constraint analysis approach

Field: Physics and Astronomy (Physical Sciences)

In this work, we use Dirac’s constraint analysis (DCA) to solve superconducting quantum circuits (SQCs). The Lagrangian of an SQC reveals the constraints that are classified in a Hamiltonian framework, such that redundant variables can be removed to isolate the canonical degrees of freedom for subsequent quantization of the Dirac brackets. We demonstrate the robustness of DCA unlike certain other set of ideas like null vector and loop charge which are each applicable only to specific types of quantum circuits.

Mathematical and deep learning modelling of the blackberries and raspberries drying kinetics

Field: Engineering (Physical Sciences)

Raspberries and Blackberries are among the most important viticultural products in Serbia. Most of them are marketed in a frozen state. Depending on the further use, to preserve nutrients as well as possible, other conservation techniques can be successfully used. Convective drying, as widely accepted method for fruit preservation is good alternative to preserve quality of these berries, primarily, and secondarily as being less demanding in terms of energy consumption. Hence, this study aims to model the drying kinetics of the selected berries using the usual semi-empirical formulas based on time-moisture ratio dependence, and with deep learning models which can include multiple parameters. Experimental part of the study was carried out in a convective dryer at different temperatures (50°C, 60°C and 70°C) and different air velocities (2 and 2.5 m/s). The effects of the operational parameters were evaluated with several quality criteria: shrinkage, color change and shape. Mathematical modelling of the drying kinetics was based on adjusting experimental data using 12 known semi-empirical models and one proposed. Besides, the experimental results were modeled with supervised deep learning techniques, a machine learning approach. The Static ANN model, RNN, and CatBoost model were selected for machine learning modelling. Optimization of the selected deep learning models was based on hyperparameter tuning. The accuracy of the evaluated and deep learning models was assessed using three metrics: coefficient of determination (R2), Mean Squared Error (MSE), and Mean Absolute Error (MAE).
Construction of strongly regular graphs having an automorphism group of composite order

Field: Mathematics (Physical Sciences)

In this paper we outline a method for constructing strongly regular graphs from orbit matrices admitting an automorphism group of composite order. In 2011, C. Lam and M. Behbahani introduced the concept of orbit matrices of strongly regular graphs and developed an algorithm for the construction of orbit matrices of strongly regular graphs with a presumed automorphism group of prime order, and construction of corresponding strongly regular graphs. The method of constructing strongly regular graphs developed and employed in this paper is a generalization of that developed by C. Lam and M. Behbahani. Using this method we classify SRGs with parameters (49,18,7,6) having an automorphism group of order six. Eleven of the SRGs with parameters (49,18,7,6) constructed in that way are new. We obtain an additional 385 new SRGs(49,18,7,6) by switching. Comparing the constructed graphs with previously known SRGs with these parameters, we conclude that up to isomorphism there are at least 727 SRGs with parameters (49,18,7,6). Further, we show that there are no SRGs with parameters (99,14,1,2) having an automorphism group of order six or nine, i.e. we rule out automorphism groups isomorphic to $Z_6$, $S_3$, $Z_9$, or $E_9$.
