Equivalent mechanical models of sloshing fluid in arbitrary‐section aqueducts

This paper reports on a semi‐analytical/numerical method to model sloshing water in an arbitrarily shaped aqueduct. The water motion is assumed to be inviscid, compressible, and linear (small displacement). The transverse sloshing fluid in an aqueduct is equivalently simplified as a fixed rigid mass M0 and a mass–spring system (M1, K1). According to a rule that the actual fluid (computed with finite element model) and its equivalent mechanical model have the same first sloshing frequency and acting effects on the aqueduct, the analytical solutions of the fixed (impulsive) mass M0, sloshing (convective) massM1, spring stiffness K1, and their locations in the aqueduct body are acquired by the least squares (curve fitting) algorithm. Applying this equivalent principle, the equivalent mechanical models are respectively obtained for the sloshing water in rectangular, semicircular, U‐shaped, and trapezoid aqueducts. The equivalent principle and fluid models are validated through comparison investigations involving rectangular and U‐shaped aqueducts. The dynamic properties and seismic responses of the original and equivalent systems are simulated, compared, and discussed for a U‐shaped aqueduct bridge. The main purpose of this paper is to provide a simplified model of sloshing fluid for the seismic/wind‐resistant computation of the support structures of the aqueduct bridge.

Behavior of NBTI under AC dynamic circuit conditions

The NBTI mechanism was investigated for a 5 nm gate oxide technology under AC dynamic circuit conditions in the frequency range of 2 MHz to 20 MHz and device "ON" duty factor in the range of 30% to 70%. The increase in the magnitude of threshold voltage, and the decrease in device current under AC operation are generally lower than that of DC operation by 3/spl times/ or higher. The time power function dependency of the degradation at sufficient stress times is lower than that of DC operation. These results indicate that more emphasis needs to be placed on AC behavior of NBTI for scaled CMOS technologies.
A Literature Review of Net Profit Margin

Net profit margin is one indicator of the company's financial performance. Net profit margin on cruise industries, for example, exhibit consistently robust growth trends for the leading cruise players, over 2016–2019, contrary to most commercial shipping market segments that experienced abrupt and persistent revenue declines since the outbreak of 2008 global financial crisis, cruise shipping has seen a robust resistance and relatively rapid recovery. Spurred by the growing importance of institutional investors, capital markets in emerging economies experience rapid growth. Specifically, equities ownership in emerging capital markets have tripled since the early 1990s. Another factor attracting equities investment involves institutional investors who offer potential for increased monitoring in the invested firms. The objective of this research is to determine the factors associated with net profit margin. I presented a literature study using systematic literature review of relevant publications and as a result of this process, 18 articles are included and then examined the bibliographical references to check the validity of the inquiry and to avoid any potential omissions. I identify several variables that affect and affected by net profit margin.
Conceptual Metaphor in Kahitna’s Song Lyrics

Every song has lyrics and every lyric undeniably contains one or two messages or ideas that a songwriter wants to express. That being said, songwriters usually use conceptual metaphors to make their songs aesthetically audible and emotionally evoking to the heart of the listeners when they hear the song or when they understand of what was written in the lyrics. Unlike the previous research that merely focused on the types of conceptual metaphors but failed to analyze the image schemas of the metaphors, this research aims at finding and describing how conceptual metaphors as well as the image schemas of the metaphors are used in Kahitna’s song lyrics. The data were analysed on the basis of Conceptual Metaphor Theory from Lakoff and Johnson’s (1980) and Kovecses’s (2010) and also Saeed’s Image Schema (2016). The research shows that there are nine conceptual metaphors found in Kahitna’s song lyrics: “Passion of Love is Sea,” “Love Story is Journey,” “Difficulty in Relationship is Journey,” “Goal of the Lovers is Journey,” “Deepest Heart is Sea,” “Heart is Container,” “Love is Container,” “Love is Concrete Object,” and “Longing is Waves. ” In addition, Containment schema, Path Schema, and Force Schema are also found in this research.
Small Alcohols as Surfactants and Hydrate Promotors

Many methods to produce hydrate reservoirs have been proposed in the last three decades. Thermal stimulation and injection of thermodynamic hydrate inhibitors are just two examples of methods which have seen reduced attention due to their high cost. However, different methods for producing hydrates are not evaluated thermodynamically prior to planning expensive experiments or pilot tests. This can be due to lack of a thermodynamic toolbox for the purpose. Another challenge is the lack of focus on the limitations of the hydrate phase transition itself. The interface between hydrate and liquid water is a kinetic bottle neck. Reducing pressure does not address this problem. An injection of CO2 will lead to the formation of a new CO2 hydrate. This hydrate formation is an efficient heat source for dissociating hydrate since heating breaks the hydrogen bonds, directly addressing the problem of nano scale kinetic limitation. Adding limited amounts of N2 increases the permeability of the injection gas. The addition of surfactant increases gas/water interface dynamics and promotes heterogeneous hydrate formation. In this work we demonstrate a residual thermodynamic scheme that allows thermodynamic analysis of different routes for hydrate formation and dissociation. We demonstrate that 20 moles per N2 added to the CO2 is thermodynamically feasible for generating a new hydrate into the pores. When N2 is added, the available hydrate formation enthalpy is reduced as compared to pure CO2, but is still considered sufficient. Up to 3 mole percent ethanol in the free pore water is also thermodynamically feasible. The addition of alcohol will not greatly disturb the ability to form new hydrate from the injection gas. Homogeneous hydrate formation from dissolved CH4 and/or CO2 is limited in amount and not important. However, the hydrate stability limits related to concentration of hydrate former in surrounding water are important. Mineral surfaces can act as hydrate promotors through direct adsorption, or adsorption in water that is structured by mineral surface charges. These aspects will be quantified in a follow-up paper, along with kinetic modelling based on thermodynamic modelling in this work.
Parameters Influencing Citizens’ Levels of Satisfaction: Soft Indicators of ‘Good Governance’

Previous studies highlighted the importance of soft indicators (e.g., quantitative sociological survey) influencing citizen satisfaction towards municipal service quality. Citizen satisfaction assessments have raised concerns over numerous independent parameters such as gender, age, and education on satisfaction levels toward administrative performance. It is also crucial to underline that the application of sociological survey for improving service quality is not well understood by municipal officers or scholars. To obtain substantial combined multiple indicators of service quality, it seems rationale to reconnoitre numerous parameters of citizen satisfaction and quantitatively investigate impacts of independent variables (e.g., gender, age, education) on corresponding satisfaction levels by using some advanced statistical tools. In this sociological assessment, a targeted population was constructed of Bangkok Metropolitan administration (BMA) stakeholders (n = 38,500), which are as follows: - Bangkok residents in 50 districts under the governance of BMA - Board committee, executive directors and general staff of 27 BMA offices This multiple dimensional analysis sociological survey data indicates that gender, age, and education play some important roles in governing municipal citizen satisfaction levels. Overall, the knowledge of relationship between citizen satisfaction levels and independent parameters can enhance the service quality of municipal administration.
Multiple Case Study on Family Therapy for Middle School Bullying Victims in South Korea

Abstract This study examines three family therapy cases of adolescents bullying victims in South Korea. We explored factors related to the onset of bullying victimization, family factors, intervention, and therapy outcome. Findings are as follows. First, the onset-related factors included hygiene issues and hostile teachers. Second, family factors were prenatal stressors, lack of affection, communication patterns, parenting practices, and transference. Third, interventions included promoting insight and coaching communication styles. Fourth, families showed cognitive and behavioral changes. Fifth, adolescents better adjusted to school. Findings suggest therapists counseling bullying victims explore family factors and help initiate changes in communication and parenting.
Social Policy Without Growth: Moving Towards Sustainable Welfare States

Growth-dependent welfare states contribute to climate emergency. The ecological economics, degrowth, and sustainable welfare literatures demonstrate that to re-embed Western production and consumption patterns in environmental limits, an encompassing social-ecological transformation would need to be initiated very soon. This article focuses on the potential roles of the welfare state and social policy in this transformation, applying the concepts of ‘sustainable welfare’ and ‘safe-operating space’. Based on two Swedish studies, it also provides an empirical analysis of the popularity of selected eco-social policies designed to steer the economy and society towards this space: maximum and basic incomes, taxes on wealth and meat, as well as working time reductions. In analogy to the historical role of the state in reconstituting the welfare-work nexus in the post-WWII era and its present engagement in the context of the Covid-19 crisis, it is argued that a more interventionist state is required to grapple with climate emergency.
Optimizing and Diversifying the Electric Range of Plug-in Hybrid Electric Vehicles for U.S. Drivers

To provide useful information for automakers to design successful plug-in hybrid electric vehicle (PHEV) products and for energy and environmental analysts to understand the social impact of PHEVs, this paper addresses the question of how many of the U.S. consumers, if buying a PHEV, would prefer what electric ranges. The Market-oriented Optimal Range for PHEV (MOR-PHEV) model is developed to optimize the PHEV electric range for each of 36,664 sampled individuals representing U.S. new vehicle drivers. The optimization objective is the minimization of the sum of costs on battery, gasoline, electricity and refueling hassle. Assuming no battery subsidy, the empirical results suggest that: 1) the optimal PHEV electric range approximates two thirds of one s typical daily driving distance in the near term, defined as $450/kWh battery delivered price and $4/gallon gasoline price. 2) PHEVs are not ready to directly compete with HEVs at today s situation, defined by the $600/kWh battery delivered price and the $3-$4/gallon gasoline price, but can do so in the near term. 3) PHEV10s will be favored by the market over longer-range PHEVs in the near term, but longer-range PHEVs can dominate the PHEV market if gasoline prices reach as high as $5-$6 per gallonmore » and/or battery delivered prices reach as low as $150-$300/kWh. 4) PHEVs can become much more attractive against HEVs in the near term if the electric range can be extended by only 10% with multiple charges per day, possible with improved charging infrastructure or adapted charging behavior. 5) the impact of a $100/kWh decrease in battery delivered prices on the competiveness of PHEVs against HEVs can be offset by about $1.25/gallon decrease in gasoline prices, or about 7/kWh increase in electricity prices. This also means that the impact of a $1/gallon decrease in gasoline prices can be offset by about 5/kWh decrease in electricity prices. « less
An evaluation of the relationship between dental anxiety and oral health in children based on maternal dental anxiety

Aim: This study aimed to understand the causes of dental anxiety that prevent optimal treatment in pediatric dental clinics and to examine the relationship between the child's dental anxiety level and the dental anxiety level of his or her parents. It also aimed to understand how the oral health of children whose parents have dental anxiety is affected by their parents’ feelings. Methodology: This study was conducted by evaluating the answers given to the Children’s Fear Survey Schedule-Dental Subscale (CFSS-DS) questionnaire, which was applied to 248 children without mental or developmental retardation who consulted the Dicle University Faculty of Dentistry between January and October 2020. The Modified Dental Anxiety Scale (MDAS) questionnaire was applied to their parents. In addition, dmft+DMFT scores were determined by performing oral examinations on the children. Results: While a statistically significant relationship was found between the dental anxiety levels of the 248 children included in our study and the dental anxiety levels of their mothers, no significant relationship was found between the dental anxiety levels of their fathers and those of the children. Those children whose mothers had high dental anxiety scores had higher dmft+DMFT scores, compared to others involved in the survey. The dmft+DMFT scores of the children with high dental anxiety were found to be higher than those of other children. Conclusion: Parents, especially mothers, play an important role in the development of children’s dental anxiety. The fact that parents with dental anxiety often avoid taking their children to the dentist prevents necessary treatments from being performed on time and causes the children’s oral health to deteriorate over time. Informing parents about reducing dental anxiety and dentists’ efforts to teach coping strategies can be helpful for minimizing the impact of parents' dental concerns on their children. By increasing mothers’ awareness of oral and dental health, it can be ensured that both they and their children will benefit more from dentistry services. How to cite this article: Çelenk S, Kol Ş.

Motion‐Induced Interruptions as Ship Operability Criteria

An important goal of operability research is the development of quantitative seakeeping criteria to permit the effects of ship motions on operations to be assessed. This paper examines the problem of developing seakeeping criteria for deck operations. The lateral force estimator is generalized to permit frequency-domain computation of the incidence of personnel losing balance in the presence of non-zero vertical acceleration. The inadequacy of roll-angle based seakeeping criteria for deck operations is shown. Other possible criteria for deck operations are discussed, and it is concluded that a limit on the number of motion-induced interruptions during deck operations is most suitable, since it is platform-independent, and may now be computed in the frequency-domain.
Heterogenous Late Holocene Climate in the Eastern Mediterranean—The Kocain Cave Record From SW Turkey

Palaeoclimate variability must be constrained to predict the nature and impacts of future climate change in the Eastern Mediterranean. Here, we present a late Holocene high‐resolution multiproxy data set from Kocain Cave, the first of its kind from SW Turkey. Regional fluctuations in effective‐moisture are recorded by variations in magnesium, strontium, phosphorous and carbon isotopes, with oxygen isotopes reacting to changes in precipitation and effective‐moisture. The new record shows a double‐peak of arid conditions at 1150 and 800 BCE, a wet period 330–460 CE followed by a rapid shift to dry conditions 460–830 CE, and a dry/wet Medieval Climate Anomaly/Little Ice Age pattern. Large discrepancies exist between Turkish records and the Kocain record, which shares more similarities with other Eastern Mediterranean coastal records. Heterogeneity of regional climate and palaeoclimate proxy records are emphasized.

Nonlinear screening designs for defense testing: an overview and case study

Recent efforts to improve the statistical rigor of both developmental and operational testing include recommendations to consider second-order screening designs. In this paper, we provide a broad review of screening designs and second-order screening designs. We then consider a real-world wind tunnel experiment case study from the recent published literature and use subject matter expertise to consider the viability of second-order screening design, a recently developed design called the DSD+, to sufficiently screen important factors in complex, nonlinear systems of interest using just a single experimental design.
Generalized Theory of the Optimum Thrust Programming for the Level Flight of a Rocket-Powered Aircraft

Two theories are presented for the analysis of the opti m u m burning program for horizontal flight. The first theory is based on Green's theorem which leads to a s imple straightforward proof of the necessary and sufficient conditions for the existence of a m a x i m u m . A linear relat ionship between thrust and engine mass flow is assumed. Hibbs' results are generalized by lifting any restriction concerning the shape of the drag polar and by considering a finite m a x i m u m burning rate for the engine. Two regions of best range are detected, one subsonic-transonic, the other one supersonic. The influence of the boundary conditions on the o p t i m u m technique of flight is discussed. A simple similarity rule for stratospheric solutions is pointed out . The second theory, based on the variational method of Lagrange multipl iers, considers the general case of an arbitrary oneto-one correspondence between thrust and propellant mass flow. Particular a t tent ion is devoted to the case of a polygonal thrust characteristic. An example of application is worked out . The concept of index value presented in a previous note is here emphasized. Such an index value appears to be a very effective device in controll ing the composit ion of the o p t i m u m path for discont inuous Eulerian solutions.
How do audiences of televised English football construct difference based on race/ethnicity?

ABSTRACT Our study analyses media audiences of football within the English context. The research question can be formulated as follows: How do young people at a Northern-England university interpret and (re)construct discourses surrounding race/ethnicity in men’s televised football? Results from our focus groups with young football media audiences show how they take a relatively race-conscious perspective in comparison to most earlier studies. At the same time, football talk appears a complex space where racialized discourses are rejected as well as accepted and where meanings given to race and ethnicity intersect with other markers of difference such as culture and nationality.
Types and role of cytological molecular analysis in thyroid carcinomas

Estimates show that thyroid nodules are commonly reported among populations residing in iodine-sufficient countries, with estimated prevalence rates of 1%, and 4% of palpable nodules among men and women in these countries, respectively. Furthermore, early diagnosis can effectively direct clinicians to the right management modality, especially in cases with malignant lesions. In this literature review, we have discussed the types and roles of cytological molecular analysis in thyroid carcinomas. Our findings indicate the molecular analysis can significantly add to the diagnostic accuracy of cytological analysis and can greatly add to the efficacy of differentiating benign from malignant lesions. We have discussed the roles of different genetic mutations that were reported among the various studies in the literature, including BRAF, RAS, PAX8/PPARγ, and RET mutations. BRAF mutations are the most validated mutations among the current studies in the literature, which has been reported to greatly increase the positive predictive values in detecting thyroid carcinomas. Some genetic mutations can be used to diagnose difficult to differentiate malignancies by fine needle aspiration (FNA) analysis. For instance, RAS mutations were reported to accurately diagnose follicular variants of papillary thyroid carcinomas that are difficult to detect using routine FNA analysis.
