Authors: Fahassa Chaymae , Abbou Ahmed , Zahraoui Yassine , Akherraz Mohamed
Published: June 2023

This research intends to establish a robust vector control (VC) of a 3-ϕ induction motor (IM). The classical 2-level inverter is displaced by a 5-level neutral-pointclamped (NPC) inverter. The 2-level inverter may only supply 8 voltage vectors, while the 5-level NPC inverter can furnish 125 voltage vectors. The objective is to bring about a command voltage vector that converges to the reference voltage vector as closely as possible; hence, guaranteeing a quick response on one hand and improving the dynamic performance on the other hand. A robust sliding mode controller (SMC) structure is used in all regulation loops. Satisfactory results are obtained for various speed zones. The quality and robustness of the global system are tested under resistive torque disturbance, reversal, high, and low-speed ranges in order to prove system stability. All the simulations have been performed under MATLAB/Simulink.
Optimization of fuzzy rules using neural network to control mobile robot in non-structured environment
Authors: A. AbuBaker Ayman , Yasin Ghadi Yazeed
Published: June 2023

It is still a challenge for all authors to control an autonomous mobile robot in an unstructured environment. The purpose of this paper is to propose a new control method for mobile robots in unstructured environments using neuro fuzzy technique. The proposed algorithm reduces the processing time of the fuzzy logic controller (FLC) inference engine. The neural network (NN) will therefore select the optimum rule(s) directly from the inference engine. This means that all of the rules of the inference engine do not need to be processed. As a result, the inference engine process speed will decrease, and the fuzzy logic response will increase. An actual mobile robot with three distance sensors and one virtual orientation angle is used to test the proposed algorithm. Based on the results, the mobile robot is capable of avoiding all obstacles and reaching the target point accurately.

Authors: Sallomi Adheed Hasan , Ahmed Ghusoon Abduljaleel
Published: June 2023

Employing electromagnetic waves in mobile communication networks has increased the level of human exposure to electromagnetic fields that may result in concerns about health hazards associated involves the soaking up of cellular phone electromagnetic energy. The human body is penetrated by the electromagnetic fields that emit from a cell phone. The specific absorption rate (SAR) that is generated in the human head and body layers usually expresses the thermal effect on human tissue. The main objective of this paper is to investigate the thermal effects of the electromagnetic field induced inside the human head and body through the construction of a simplified model for both. The RF-source and human body models are built by using the ANSYS high-frequency structural simulator (HFSS). A planar inverted-F antenna (PIFA) will use to assign SAR values to different body tissues for the fourth generation (4G) of mobile phone communication at an operational frequency of 2.6 GHz and power radiated of 125 mW. The model is simulated and analyzed to evaluate the SAR induced at different human tissues depending on the source-to-antenna distance and its generated values must not exceed the safe limits for harmful thermal effects.

Published: June 2023

The existence of machine learning has been exploited to solve difficulties in various fields, including the classification of leaf species in agriculture. Betel leaf is one of the plants that provide health advantages. The objective of using a machine learning approach is to classify the betel leaf species. This study involved several processes: image acquisition, region of interest (ROI) detection, pre-processing, feature extraction, and classification. The feature extraction used the combination features of color and texture. Furthermore, the classification applied four classifiers, including artificial neural network (ANN), K-nearest neighbors (KNN), Naive Bayes, and support vector machine (SVM). The evaluation in this study implemented cross-validation with a K-fold value of 5. The method performance produced the highest accuracy value of 100% using the color and texture features with the SVM classifier.

Authors: Bektaş Yasin , Karaca Hulusi , Taha Taha A. , Zaynal Hussein I.
Published: June 2023

This paper proposed a red deer algorithm (RDA)-based selective harmonic elimination (SHE) method for multilevel inverters (MLIs). To eliminate the desired harmonic orders, the optimum switching angles of the MLI have been calculated using the proposed RDA. The calculated switching angles have been applied to the 3-phase cascaded H-bridged 11-level inverter. In addition, the performance of the proposed RDA method was compared with the results of methods such as the Newton-Raphson (NR) method, LSHADE/EpSin technique (LSHADE), whale optimization algorithm (WOA), and particle swarm optimization (PSO) used for the SHE problem in the literature. The results obtained prove that the proposed RDA optimization solves the SHE problems more effectively than other methods. It has also been observed that RDA produces good solutions in different modulation indexes.

Published: June 2023

The pomising uses of near infrared (NIR) phosphor converted light emitting diodes (pc-LEDs), including non-destructive testing and biological implementations, are endless. It is still difficult to create wideband and NIR phosphors with sufficient heating steadiness for a variety of uses. The study herein introduces the phosphor Sr3Ga2Ge4O14:Cr3+, its creation procedure through expreiments as well as its influneces on LED devices. The Sr3Ga2Ge4O14:Cr3+ (SGGO:Cr3+) super-wideband NIR phosphor was effectively synthesized in this study with 431 nm stimulation, and a spectrum adjustment 750 nm-900 nm was made in a two-step superwideband radiation having its full width under half maximum (FWHM) changing among 257 and 336 nm. The inner quantum performance (IQP) for SGGO:0.15Cr3+ is 36.67%, and it has an FWHM of 257 nm. At 423 K, the emitting strength was still 76% of ambient temperature. The potential of SGGO:Cr3+ for various uses was eventually demonstrated by the employment of SGGO:0.03Cr3+ as well as SGGO:0.15Cr3+ samples accompanied by blue illumination chips under 430 nm for the task of creating NIR pc-LED gadgets then putting in nighttime sight, human palm puncture, flora lighting. It was shown that SGGO:Cr3+ has a wide range of use possibilities.

Authors: Rengarajan Guruprasath , Ramalingam Nagarajan , Suriyan Kannadhasan
Published: June 2023

Due to the dynamic topology and limited resources in mobile ad hoc networks (MANETs), multicast routing and quality of service (QoS) provisioning are difficult issues. This study introduces an agent-based QoS routing method that uses fuzzy logic to choose the best route while taking into account a variety of independent QoS indicators, including buffer occupancy rate, remaining mobile node battery capacity, and hop count. On the other hand, finding such pathways requires a lot of work in terms of efficiency and security. This study continues to test the security of weak models, and it has been shown that it may be challenging to accept various sorts of assaults. A distributed approach is given that may be used to determine the best resource distribution at each node. Additionally, the least energy-intensive directed acyclic network network flow is selected from a group using the embedded sleep scheduling algorithm. The process of choosing the flow and allocating the resources for each video frame is adjusted to the characteristics of the network connection channel. Results show that the suggested resource allocation and flow selection algorithms provide considerable performance benefits with minimal optimality gaps at a reasonable computational cost when applied to various network topologies.

Solutions of economic load dispatch problems for hybrid power plants using Dandelion optimizer
Authors: Nguyen Hung Duc , Pham Ly Huu
Published: June 2023

In this paper, an economic load dispatch problem (ELD) is solved for reaching optimal power output of hybrid systems in addition to cost minimization. The systems consider the forbidden working zones (FWZs), dynamic load demand, wind farms, and solar photovoltaic fields (SPs). The cost minimization solutions for the ELD problem are found by applying the Dandelion optimizer (DO), the salp swarm algorithm (SSA), and the particle swarm optimization (PSO). In the study case, the power system consists of six thermal power plants (TPs), two wind farms, and two SPs. In addition, the variation of load demand over 24 hours of one day is applied. DO and SSA can achieve the best cost of $15443.0753 for the first system, but PSO cannot. However, DO is the most stable method reaching the standard deviation of 0.0184 for fifty runs but that of SSA and PSO is about 1.0439 and 8.9664. For the second system, DO can reach smaller cost than PSO by $11.17, $137.74 and $323.09 for the best, mean and worst solutions among fifty found solutions. As a result, DO is strongly recommended for solving the ELD problem.

Authors: Bouali Hamid , Benhala Bachir , Guerbaoui Mohammed
Published: June 2023

This paper presents the application of two swarm intelligence techniques, multi-objective artificial bee colony (MOABC) and multi-objective particle swarm optimization (MOPSO), to the optimal design of a complementary metal oxide semiconductor (CMOS) low noise amplifier (LNA) cascode with inductive source degeneration. The aim is to achieve a balanced trade-off between voltage gain and noise figure. The optimized LNA circuit operates at 2.4 GHz with a 1.8 V power supply and is implemented in a 180 nm CMOS process. Both optimization algorithms were implemented in MATLAB and evaluated using the ZDT1, ZDT2, and ZDT3 test functions. The optimized designs were then simulated using the advance design system (ADS) simulator. The results showed that the MOABC and MOPSO techniques are practical and effective in optimizing LNA design, resulting in better performance than previously published works, with a gain of 21.2 dB and a noise figure of 0.848 dB.
An outline of solar photovoltaic systems impact on environment
Authors: Vunnam Sarayu , VanithaSri Muniyamuthu , Alla RamaKoteswaraRao
Published: June 2023

The damaging environmental repercussions of energy production are greatly reduced when renewable energy sources are used. Solar photovoltaic (PV) energy is reliable and secure, and it also includes benefits like no noise, no pollution, easy maintenance, and no environmental harm. Solar PV technology has emerged as the renewable energy source with the greatest rate of expansion worldwide since fossil fuels are soon running out and have a negative influence on the environment. PV modules reduce carbon dioxide emissions, preserving the environment and preventing global warming. The solar cell efficiency is one of the key elements in developing this PV technology. To increase solar cell efficiency for commercial use, the type of material used in production is essential. After serving its purpose, a PV module can be recycled, and environmentally appropriate disposal won't have much of an effect on the environment. In this article, the impact of solar PV systems and their most recent advancements for environmental preservation are discussed.

Published: June 2023

In recent years, there is growth in acceptance to consume fewer fossil fuels globally and the manufacturing of electric vehicles (EVs) has become more popular. However, the increase in the number of systems connected to the grid that contain EVs with a huge power capacity leads to unstable working in the power system. To assess the stability of the electric charging station several control approaches in AC part and DC parts during charging mode and discharging modes are tested. African vulture optimization algorithm (AVOA) has been utilized to tune the system controllers (proportional integral derivative (PID)/tilt integral derivative (TID) controllers). The superiority of AVOA is confirmed by comparing the performance with the genetic algorithm (GA). Two objective functions have been used i.e. integral time absolute error (ITAE) and integral square time error (ISTE). AVOA-tuned TID controllers using ISTE were found to be the best to contain the frequency deviations. The results have shown of the AC part and DC part is within an acceptable limit recommended by IEEE standard. Further, maximum peak overshoot, undershoot, and settle time obtained by AVOA-tuned PID and TID controllers are found the best. Finally, the improvement of the performance index obtained by AVOA over its counterpart GA is confirmed.

Discute o conceito de mediação como multifacetada, polissêmica e transitória ocorrendo no “saber correr atrás” (de benefícios) de atores na conexão entre domínios familiares de cuidado que se organizam por uma moral de relacionalidade cotidiana, do domínio de serviços de atendimento e gestão com uma moral de preservação do sistema de atendimento, e do domínio de pesquisadores com uma moral de conhecimento. Argumenta que a prática de mediação usa e preserva as redes no domínio do mediador, mostrando a sua conexão complementar a outro domínio através de ações especificas, expressando emoções em diferentes intensidades que contribuem à confiabilidade mutua e consecução de serviços. Exemplifica a atuação de quatro mediadoras dos serviços de atendimento e de gestão, duas de equipes de pesquisa, e duas de associações que representam as famílias. Termina realçando a importância do tempo emergencial na criação de mediação mais intensa enquanto a transitoriedade do evento da epidemia desfavorece continuidades.
‘No One Seems to Notice the Dress’: Three Benedictines at Large in Hastings, 1897
Authors: Anderson Roberta
Published: June 2023

In 1897, after several nasty bouts of bronchitis, the Abbess of St Mary’s, East Bergholt, Lady Gertrude Lescher, was recommended a change of air, and, since her last attack, her physician, Dr Carey, now insisted that it was imperative for her to convalesce in clearer air. Mother Prioress, Dame Margaret Mary Lescher, laid the matter before the Bishop, who at once agreed that the Doctor’s orders should be obeyed. Carey recommended that Hastings would be the most suitable place and plans were into place. This article is based on the diaries and letters of the Dames during their stay in Hastings which are preserved in the Haslemere Collection at Downside Abbey Library and Archive.
The Effects of Global Value Chain on Export Survival
Authors: Doan Ngoc Thang , Le Thanh Ha
Published: June 2023

This article uses panel data with 6,743 country-year observations to investigate the effects of participation in the global value chain (GVC) on export survival rate for the period 2005–2014. GVC participation is measured as the value addition embedded in exports, looking both backward and forward from a reference country. The empirical results show that both backward and forward linkages have positive effects on the chance of export survival; these effects are persistent and increasing over time, and they become more pronounced when taking the endogeneity issue into account. On the policy front, the preceding findings suggest that governments should implement policies to upgrade a country to GVC integration in order to enhance the sustainability of exports.

Effect of Taste-Induced Mood on ERP and Emotional Assessment of Images
Authors: Wada Erika , Ogawa Keiko
Published: June 2023

Tastes affect the body and our emotions. We used tasteless, sweet, and bitter stimuli to induce participants’ moods, and we examined the effect of mood on an emotional evaluation of pleasant, neutral, and unpleasant images using event-related potentials, N2, N400, and late positive potential (LPP), which reflect emotional evaluation in the brain. The results indicated that mood valence was most positive for sweetness and most negative for bitterness. Moreover, there was no significant mood effect on subjective valence ratings of emotional images. Furthermore, the N2 amplitude, which is related to the early semantic processing of preceding stimuli, was unaffected by the taste induced mood. In contrast, we found that the N400 amplitude, which is related to the mismatch of emotional valence between stimuli, increased significantly for unpleasant images when participants were in a positive rather than negative mood state. Also, the LPP amplitude, which is related to the emotional valence of images, showed only the main effect of the images’ emotional valence. The N2’s results suggest that the early semantic processing of taste stimuli might have had a negligible impact on emotional evaluation because taste stimuli minimize semantic processing that accompanies mood induction. In contrast, the N400 reflected the effects of the induced mood, and the LPP reflected the impact of the valence of emotional images. The use of taste stimuli to induce mood revealed different brain processing of taste-induced mood effects on emotional evaluation, including N2’s involvement in semantic processing, N400’s involvement in matching emotions between mood and stimuli, and LPP’s involvement in subjective evaluations of stimuli.

Authors: Li Xiaoyu , Yang Pengcheng
Published: June 2023

The new generation of employees has emerged as a major force in the labor market, and their employee experience has become a significant factor in transforming the employment relationship. The objective of this study is to see if perceived organizational support influences the employee experience of the new generation of employees. Also, considering that the underlying mechanisms between the two are unclear, this study explores the mediating role of proactive personality and the moderating role of emotional exhaustion. This study used the Perceived Organizational Support Scale, Employee Experience Scale, Proactive Personality Scale, and Emotional Exhaustion Scale to survey 550 new-generation employees in China. The results showed that: perceived organizational support facilitated the level of employee experience of new generation employees; proactive personality partially mediated the relationship between perceived organizational support and employee experience. In addition, emotional exhaustion moderated the relationship between perceived organizational support and proactive personality. This study reveals the mechanisms of organizational and individual factors on the employee experience of new generation employees, explores the growth path of employee experience of new generation employees, and provides insights into the management practice work of business leaders.
Warthin-like mucoepidermoid carcinoma of the parotid gland: Clinicopathological observation and literature review
Authors: Yan Limin , Xu Jinheng , Liu Liyun , Li Xin
Published: June 2023

Warthin tumor (WT)-like mucoepidermoid carcinoma resembles the histologic pattern of WT and pathologists unaware of this possibility may misdiagnose it as WT with squamous and mucous epithelium metaplasia or WT malignant transfer into mucoepidermoid carcinoma. The present study reported a case of a 41-year-old Chinese female with a solitary mass in the left parotid gland. In this case, microscopic observation revealed prominent lymph node stroma and multiple cystic structures similar to those seen in WT. However, it lacked the two layers of oncocytic epithelial tissue characteristic of WT. Furthermore, fluorescence in situ hybridization detected MAML2 rearrangement in the case. Considering the histological findings, this case was diagnosed as WT-like mucoepidermoid carcinoma. The present case report provides pathological and clinical features to differentiate it from WT malignant transition into mucoepidermoid carcinoma, WT with squamous and mucous epithelium metaplasia and non-sebaceous lymphadenoma-like mucoepidermoid carcinoma. In conclusion, WT-like mucoepidermoid carcinoma as a special subtype of mucoepidermoid carcinoma has special histological characteristics, which required further observations and more case reports to clearly define this variant.
School and residential segregation in the reproduction of urban segregation: A case study in Buenos Aires
Authors: Serrati Pablo Santiago
Published: June 2023

The link between residential and school segregation is widely recognised as a key to explaining urban inequalities. However, most studies have focused on countries of the Global North. This paper attempts to identify to what extent socio-economic residential segregation explains secondary school segregation in Buenos Aires (Argentina). Based on a linear programming method, the study proposes a hypothetical pupil allocation model that takes into account the capacity of schools and is used as an ideal typus to compare with the real socio-economic school composition. Using a ‘decompose method’ of segregation differences to analyse the differences in segregation indices and a local segregation analysis, this paper finds that in a residential context with low segregation but high social inequalities, school segregation is a social mechanism that allows maintaining spaces of differentiation and distancing between groups. In discussion with the idea of a ‘vicious circle of segregation’, this article argues for the potential of a multi-domain approach to segregation, to understand how different domains work in articulated and complex ways to reinforce urban segregation.
Do Good Citizens Look to the Future? The Link Between National Identification and Future Time Perspective and Their Role in Explaining Citizens’ Reactions to Conflicts Between Short-Term and Long-Term National Interests
Authors: Jamróz-Dolińska Katarzyna , Sekerdej Maciej , Rupar Mirjana , Kołeczek Maryna
Published: June 2023

When people consider what is good for their country, they might face a conflict between the country’s short-term and long-term interests. We suggest that resolving this conflict depends on people’s form of national identification and future time perspective. Across four studies ( N = 4,274), we showed that constructive patriotism, but not conventional patriotism or glorification, was positively associated with future time perspective. Moreover, we showed that this further translated into people’s responses to intertemporal conflicts. Specifically, constructive patriotism was indirectly linked to higher support for national policies with long-term advantages (despite short-term disadvantages) and lower support for national policies with long-term disadvantages (despite short-term advantages), and these links were mediated by future time perspective. Overall, our results demonstrate that distinct forms of national identification are differently linked to future time perspective. Likewise, this helps explain differences in how much people care about their country’s present and future.
Toward an Index of Adaptive Personality Regulation
Authors: Irwing Paul , Cook Clare , Hughes David J.
Published: June 2023

The idea that matching personality expression with situational demands is adaptive is implicit in many accounts of personality. Numerous constructs and measures have been posited to address this or similar phenomena. Few have proven adequate. In response, we proposed and tested a novel measurement approach (the APR index) assessing real-time behavior to rate participants’ success in matching personality expression with situational demands, which we denote adaptive personality regulation. An experimental study ( N = 88) and an observational study of comedians ( N = 203) provided tests of whether the APR index constituted a useful metric of adaptive personality regulation. In both studies, the APR index showed robust psychometric properties; was statistically unique from mean-level personality, self-monitoring, and the general factor of personality expression; and provided incremental concurrent prediction of task/job performance. The results suggest that the APR index provides a useful metric for studying the phenomenon of successfully matching personality expression to situational demands.
The Cultural Production of Everyday Ethics in Two University STEM Labs
Authors: Mickel Allison , Heidebrink-Bruno Adam , Hosseiny Marani Amin , Barone Isabel , Lee Olivia , Baumer Eric P.S.
Published: June 2023

How do ethics show up in the everyday behaviors and conversations of researchers in a scientific laboratory? How does the microcosmic culture of the laboratory shape researchers’ understandings of scientific ethics? We, an interdisciplinary team representing anthropology, computer science, and rhetorical studies, investigated these questions in two university STEM labs. Similar to previous work mapping out the epistemic cultures, we sought to understand the ethical cultures of these research groups. We observed their lab meetings for several months and conducted interviews with members of the research laboratories. Ultimately, we recognized two distinct ethical cultures within the two laboratories: one focused on the relationship between science and social justice, and the other focused on clean data and accuracy as an ethical issue. These two distinct ethical cultures were discernable through ethnography, close reading of laboratory members’ language, as well as broad-scale topic modeling. Our project complements previous studies of ethics in science that have focused on codes of ethics or student curricula as ways in which scientists develop an understanding of scientific ethics. Our project demonstrates that everyday interactions between the members of scientific research labs additionally shape, at a decidedly local level, how scientists understand and ultimately approach ethical decision-making in the scientific research process.
Effects of cortical distance on the Ebbinghaus and Delboeuf illusions
Authors: Urale Poutasi W. B. , Schwarzkopf Dietrich Samuel
Published: June 2023

The Ebbinghaus and Delboeuf illusions affect the perceived size of a target circle depending on the size and proximity of circular inducers or a ring. Converging evidence suggests that these illusions are driven by interactions between contours mediated by their cortical distance in primary visual cortex. We tested the effect of cortical distance on these illusions using two methods: First, we manipulated retinal distance between target and inducers in a two-interval forced choice design, finding that targets appeared larger with a closer surround. Next, we predicted that targets presented peripherally should appear larger due to cortical magnification. Hence, we tested the illusion strength when positioning the stimuli at various eccentricities, with results supporting this hypothesis. We calculated estimated cortical distances between illusion elements in each experiment and used these estimates to compare the relationship between cortical distance and illusion strength across our experiments. In a final experiment, we modified the Delboeuf illusion to test whether the influence of the inducers/annuli in this illusion is influenced by an inhibitory surround. We found evidence that an additional outer ring makes targets appear smaller compared to a single-ring condition, suggesting that near and distal contours have antagonistic effects on perceived target size.
One or many? The grammatical number of suffixed nouns as a text-critical problem
Authors: Krusche Marcel
Published: June 2023

One of the most frequent cases of textual variance in the Hebrew Bible concerns the grammatical number of nouns with suffixes (e.g. ידך‎ ‘your hand’ versus ידיך‎ ‘your hands’). First, this article demonstrates the significant textual instability of the letter yod in the plural or dual morphemes of suffixed nouns and traces some reasons for that. Then, it presents exemplary cases of this variance and discusses some interpretive conclusions drawn from conspicuous grammatical numbers in the research literature. For instance, a widespread theory that distinguishes two kinds of hand imposition rites according to the number of hands used by the performing subject proves to be problematic for text-critical and philological reasons. Finally, the article discusses the appropriate text-critical handling of the problem in general, suggests some guidelines, promotes awareness of ambiguity, and pleads for restraint in drawing far-reaching interpretive conclusions from a specific grammatical number of suffixed nouns.
Revisiting Sir Robert Bristow's ‘India’: A post-colonial analysis of Cochin Saga
Authors: Vinai Maya , Mithuna S. M.
Published: June 2023

Sir Robert Bristow, popularly called Bristow Sahib, is recognized as a path-breaker in the field of port construction in the historical consciousness and cultural imaginary of the people of Kerala, the southernmost state of India. His memoir, Cochin Saga, published in 1959, records both his professional experiences as a harbour engineer and his personal reminiscences as a British resident posted in Cochin. Maritime scholarship has paid scant attention to this literary document, which is a crucial record of how Bristow succeeded in winning hearts in an alien culture, overcoming hostile environmental situations. This article attempts to reconsider Bristow's memories as recorded in Cochin Saga from a post-colonial perspective, and tries to examine whether Bristow's accounts fall prey to employing universalizing tendencies and a hegemonic world view of India and its culture.

Books known only by title
Authors: Lied Liv Ingeborg , Kartzow Marianne Bjelland , Brownsmith Esther
Published: June 2023

This special issue of the Journal for the Study of the Pseudepigrapha aims to introduce the concept of “books known only by title” as a fruitful new focus of research in the larger field of first-millennium Jewish and Christian literatures. Books known only by title are named literary objects known only through the medium of other writings, surviving neither as extant documents nor as excerpts or quotations of any substantial length. Still, these books are far more than “lost,” “false,” or “forged”: they were vital components of the first millennium literary imagination. This introductory essay provides a conceptual and methodological framework for the study of this hitherto unexplored phenomenon and offers an initial overview of key functions of books known only by title in book lists and literary texts.
On a numerical methodology to assess the fatigue life of connecting rods
Authors: Xu Wentao , de Bretagne Olivier Le Roux , Grasso Marzio , Harrison Matthew F , Carless Owen , StLeger-Harris Chris
Published: June 2023

Although simulation-based fatigue analysis is a standard tool adopted in every sector including automotive industry, the design of engine components in automotive and motorsport applications mostly relies on simplified design approaches supported by time-consuming testing programs. This manuscript proposes a new methodology based on individual engine speed damage estimation and engine speed time history combined with Palmgren-Miner linear damage rule to predict the fatigue state of the connecting rod. The track data, engine multibody simulation (AVL ExciteTM) and engine combustion simulation (AVL BoostTM) are used to generate the initial variable trace that is processed to obtain the block programs. Stress amplitude estimated with finite element analysis (Abaqus) are used to estimate the damage from S-N curve and the cumulative damage is estimated with Palmgren-Miner cumulative damage model. The method proposed is demonstrated using a connecting rod case study and the duty cycle from the race on Sebring international raceway. This work shows the suitability of the approach and the benefit in terms of accuracy in the prediction of the fatigue life.
A novel experimental control method to suppress instability in a centrifugal compressor with two counter and co-rotating rotors
Authors: Abed Cheikh Brahim , Nguyen Van-Thang , Khelladi Sofiane , Deligant Michael , Danlos Amelie , Bakir Farid
Published: June 2023

The use of a counter-rotating rotor in turbomachines can be a solution to improve performances by allowing reduction in size and weight, especially compared to multistage configuration. The present study aims are to demonstrate another advantage of the counter-rotating rotors: their application to expand the operating range of centrifugal compressors toward extremely low flow rates based on an active control method. This method was performed on two different counter-rotating configurations. The principle of the active control method is to adjust independently the rotation speed of each rotor to push back the instability appearance. Experimental results show that reducing the rotation speed of the upstream-rotor while fixing the speed of the downstream rotor can push the instability phenomenon toward a lower mass flow rate while decreasing the pressure rise and efficiency. Co-rotating mode is applied to push further the stable region toward low mass flow rates allowing a significant extension of the operating range. The experimental results reveal that the map width is shifted by about 50% over the studied range toward a lower mass flow rate for both counter-rotating centrifugal compressors when using the control method. This can be achieved when the absolute value of the upstream-rotor speed is within the range of 48%–61% of the rotational speed of the downstream rotor.

Thickening the foundation slab and improving the subgrade soil using geo-techniques are effective measures for controlling unwanted vibrations at high-tech facilities. In this study, the vibration-reduction performance of 1-m-thick concrete slabs with natural and cement-improved subgrades was investigated based on in situ frequency sweep tests. One 1-m-thick concrete slab rested on 1-m-thick compacted sandy gravel backfill atop an undisturbed subgrade was constructed on the north side of the experimental site, and another identical concrete slab rested on 1-m-thick compacted sandy gravel backfill atop a cement-improved subgrade was constructed on the south side. The vibration-reduction effect was evaluated by comparing the free-field ground vibrations and surface vibrations of the two slabs at three pairs of evaluation locations. In terms of peak velocity, the 1-m-thick concrete slab with the natural subgrade exhibited a slight vibration amplification effect at low frequencies and a significant reduction effect at middle and high frequencies; the 1-m-thick concrete slab with the cement-improved subgrade exhibited a continuous vibration reduction action at all frequencies. In terms of RMS velocity, the vibration-reduction performance of the 1-m-thick concrete slab with the cement-improved subgrade was better than that with the natural subgrade. The results demonstrated that the vibration-reduction effect of the thick concrete slab was significant and could be increased by improving the subgrade using the cement grouting method.

Introduction

Medication reconciliation as part of a Comprehensive Geriatric Assessment by a specialist pharmacist is a process that has been shown to be beneficial in terms of medication adherence in patients taking oral anticancer medication and potentially cost-effective in cancer patients. Medication review guidelines in older adults with cancer suggest using polypharmacy (≥ 5 medications) as an indication for medication review in older adults with cancer.

Case report

We present a case where a medication review as part of a Comprehensive Geriatric Assessment in the absence of polypharmacy resulted in two pharmacist interventions when standard care resulted in no intervention. A 71-year-old male prescribed capecitabine for rectal cancer had a medication reconciliation done as standard care before starting an oral anticancer medication. He then proceeded to get a medication review as part of a Comprehensive Geriatric Assessment and was deemed to have a potentially excessive anticholinergic burden and underprescribed gastro protection. This case is interesting as it occurred in a patient who would not have met the current inclusion criteria for a medication review as part of a Comprehensive Geriatric Assessment.

Management and outcome

As a result of the Comprehensive Geriatric Assessment, a letter was written to the patient's general practitioner, recommending a change to anti-depressant therapy to optimise anticholinergic burden, as well as introducing a proton-pump inhibitor upon completion of the Capecitabine protocol concurrent with radiotherapy, to confer gastro-protection against the antidepressant medication, as per the START criteria. Upon discharge from medical oncology, neither of the changes had been adopted by the patient's general practitioner. This highlights one of the challenges facing clinical pharmacists in an outpatient setting, where evidence-based recommendations are not always implemented as care transitions from tertiary to primary care.

Conclusion

Comprehensive Geriatric Assessment is a process that identifies potential issues in older adults with cancer that aren’t identified with standard medication review. This is also evident for medication reviews as part of a Comprehensive Geriatric Assessment, and where resources allow, and recommendations are likely to be accepted, it should be offered to all older adults with cancer. Pharmacists are still faced with challenges in implementing recommendations from medication reviews, particularly in healthcare systems where pharmacist prescribing has yet to be introduced.
Correlations of Placental Histopathology, Neonatal Outcome, and Cardiotocogram Baseline Variability and Acceleration Patterns in the Growth Restricted Preterm Population
Authors: Dankó István , Kelemen Edit , Tankó András , Cserni Gábor
Published: June 2023

Objective:

To evaluate the possible connections of cardiotocography (CTG) signs with neonatal outcome and placental histopathology between growth restricted preterms.

Materials and Methods:

Placental slides, baseline variability, and acceleration patterns of cardiotocograms, and neonatal parameters were studied retrospectively. Placental histopathological changes were diagnosed according to the Amsterdam criteria; percentage of intact terminal villi and capillarization of villi were also studied. 50 cases were analyzed: 24 were early-onset fetal growth restriction (FGR), 26 were late-onset FGR.

Results:

Reduced baseline variability was related to poor neonatal outcome; lack of accelerations similarly had associations with poor outcomes. Maternal vascular malperfusion, avascular villi, VUE, and chorangiosis were more common in the background of reduced baseline variability and absence of accelerations. Lower percentage of intact terminal villi was significantly associated with lower umbilical artery pH, higher lactate levels, and reduced baseline variability on CTG; absence of accelerations was correlated with decreased capillarization of terminal villi.

Conclusions:

Baseline variability and absence of accelerations seem to be useful and reliable markers in predicting poor neonatal outcome. Maternal and fetal vascular malperfusion signs, decreased capillarization, and lower percentage of intact villi in placenta could contribute to pathologic CTG signs and poor prognosis.
Up in the air: Ritualized atmospheres and the global Black Lives Matter movement
Authors: Solomon Ty
Published: June 2023

How did the Black Lives Matter (BLM) movement of 2020 resonate at a global level? And how did the ritual practices of the movement spread internationally? International Relations (IR) has seen increasing interest in the role of rituals in global politics, and the wider literature on rituals often explores their stabilizing effects while noting how rituals function by working on the collective emotions of participants. Yet what particular kinds of emotional processes lend rituals their power? And how do these ritual emotions disrupt prevailing power structures? This article proposes that conceptualizing these experiences as ritualized atmospheres opens up at least two new avenues for research on rituals, emotions, and global social movements in IR. First, ritualized atmospheres are characterized by their viscerally felt yet also intangible and diffuse features. These tensions offer an affective account of rituals’ often-noted constitutive dual pull between the materialization of political communities while also constructing them as emotionally charged abstractions. Second, the tensions and ambiguities of ritualized atmospheres can generate new horizons for thoughts and actions. Ambient shifts in collective mood can change what may be thought, said, and practiced within ritual contexts, allowing for new discourses and new forms of political action. The article pursues the question of BLM’s global resonance by way of developing these conceptual and empirical arguments.
Tourism demand with subtle seasonality: Recognition and forecasting
Authors: Wang Haiyan , Hu Tao , Wu Huihui
Published: June 2023

Existing studies on tourism seasonality have been mainly identified at annual or monthly level and the seasonality in tourism demand forecasting has always been addressed by modeling season patterns. However, annual or monthly seasonality is coarse-grained and can’t capture the subtle changes emerging both in tourism theory and practice. This study recognizes tourism seasonality based on intra-day patterns and inter-day similarity and suggests a novel approach to addressing seasonality in tourism demand forecasting. The proposed three-step method contains tourism seasonality recognition, tourism seasonality matching, and tourism demand forecasting. The empirical findings, based on two attractions in China, demonstrate that the proposed method based on dynamic time warping and density-peak clustering can precisely capture tourism seasonality at the daily level. The method can also detect special tourism periods or subtle changes in seasonality, such as staggered peak travel phenomenon. Superior forecasting performance with seasonality matching is also revealed. This study sheds new light on tourism seasonality recognition and contributes to forecasting methodology.
Low and high outcome quality in co-created hospitality services: Two explanations for consumer satisfaction
Authors: Alarcón-López Rocío , López-López Inés , Ruiz-de-Maya Salvador
Published: June 2023

Nowadays, co-creation is a significant trend in the hospitality industry. Through two experiments, this paper investigates the effects of low and high outcome quality resulting from co-creation on consumer satisfaction. In particular, we examine engagement and emotions as the underlying mechanisms that mediate the relationship between outcome quality and satisfaction. Our findings build upon a service-dominant logic framework and indicate that outcome quality influences customer satisfaction, with emotions acting as a mediator for low-quality outcomes and engagement as a mediator for high-quality outcomes. Interestingly, engagement operates in low outcome quality settings and partly compensates for a suboptimal result, highlighting the key role co-creation can play in the event of a failed encounter. This article contributes to co-creation literature as well as to the ongoing methodological debate on emotion measurement. In addition, it offers managerial insightful directions for hospitality companies.
