Finite element simulations and experimental verifications for forming limit curve determination of two-layer aluminum/brass sheets considering the incremental forming process

Field: Engineering (Physical Sciences)

In this paper, forming limit diagram (FLD) of aluminum/brass two-layer sheets through an incremental forming process (ISF) was studied numerically and experimentally. At first, the two-layer aluminum 1050/brass (65% copper) sheets were fabricated using the roll bonding process. Also, the finite element simulations of the incremental forming process with ABAQUS software were utilized to predict the FLD. For this purpose, the criterion of the second derivative of the equivalent plastic strain was used to predict fracture. Finally, the numerical simulation results were compared with the experimental results. For instance, comparing experimental and numerical FLD 0 values for the formed samples with forming angle 62.5-degree showed a 7% difference. However, the difference was negligible, and numerical simulation results could be used with an appropriate reliability coefficient. The effect of sheet arrangement towards tools was then investigated. It finds out from the experimental results that the formability of the Brass/Al (brass was up layer and aluminum was bottom layer) was more than the Al/Brass (aluminum is up layer and brass is bottom layer). In the following, the ISF parameters such as forming limit angle, step-down, and thickness distribution were investigated.
Measuring mechanical impedance in clayey gravelly soils

Field: Agricultural and Biological Sciences (Life Sciences)

Mechanical impedance of clayey and gravelly soils is often needed to interpret experimental results from tillage and other field experiments. Its measurement is difficult with manual and hydraulic penetrometers, which often bend or break in such soils. The purpose of this study was to evaluate the feasibility of a hand-operated "Stolf" impact penetrometer to measure mechanical impedance (soil resistance). The research was conducted in Raleigh, North Carolina, USA (35º 45'N, 78º 42'W, elevation 75 m). Corn was planted on April 19, 1991. Penetrometer measurements were taken on May 10, 1991, in 5 cm intervals to 60 cm at 33 locations on a transect perpendicular to the corn rows in each of four tillage treatments. The data permitted three-dimensional displays showing how mechanical impedance changed with depth and distance along the transect. The impact penetrometer proved to be a useful tool to collect quantitative mechanical impedance data on "hard" clayey and/or gravelly soils which previously were difficult to reliably quantify.
Hybrid Practices in Global Software Development: A Systematic Literature Review

Field: Computer Science (Physical Sciences)

Although agile methods in their purest way fit several companies, it has been a challenge to perform them in environments with distributed teams developing large software applications. Contractual items, for projects under development for external organizations, introduce additional complexities for pure agilebased approaches. The majority of global teams and companies use hybrid development practices that combine different development methods and frameworks. This research provides results from an empirical field study on how the hybrids practices are adopted in Global Software Development (GSD) projects. A systematic literature review was conducted to capture the status of combining agile with plan-driven in GSD projects. The results were limited to peer-reviewed conference papers or journal articles, published between 2001 and 2020. The present study selected 37 papers from five different bibliographic databases. In the end, 16 practices were summarized and described as hybrid by GSD projects. Based on the findings of this study, the authors can conclude that the contribution of this study is not only limited to identifying how hybrid development practices are applied in GSD but also allowing that practitioners can have a basis for adapting their development methods.
Experimental study on the simultaneous desulfurization and denitrification by duct injection.

Field: Environmental Science (Physical Sciences)

The highly active absorbent with oxidization based on fly ash, lime and additive was prepared. Experiments of simultaneous desulfurization and denitrification were carried out using fixture bed and duct injection. The influencial factors for the absorptive capacity of the absorbent were studied. The absorptive capacities of 120.7 mg for SO2 and 43.7 mg for NOx were achieved at a Ca/(S + N) molar ratio 1.2, respectively, corresponding removal efficiencies of 87% and 76%, while spent absorbent appeared in the form of dry powder. The optimal temperature and humidity of flue gas treated with this process were shown to be approximately 50 degrees C, and 5% respectively. The mechanism of removal for SO2 and NOx was investigated. In comparison with traditional dry FGD, this process appears to have lower cost, less complicated configuration and simpler disposal of used absorbent. The valuable references can be provided for industrial application by this process. The foreground of application will be vast in China and in the world.
The use of new‐media marketing in the green industry: Analysis of social media use and impact on sales

Field: Business, Management and Accounting (Social Sciences)

Abstract During the recession, the decline in home value and home ownership reduced the demand for ornamental plants, lawn and garden products, and related services, which resulted in significantly negative effect on the green industry revenues. Postrecession consolidation in the United States green industry has forced smaller firms to re‐evaluate their marketing strategies. New‐media marketing has gained attention as a relatively low‐cost and high‐exposure marketing strategy. This paper utilizes binary logit and interval censored regression to examine the use and the impact of social‐media marketing in the green industry. The analysis was based on primary data from a survey of US nurseries and garden centers. The findings reveal that the daily use of social‐media marketing is largely driven by the network effect and the managers’ attitudes. They also indicate that the small‐sized firms receive higher returns from social media use in terms of increased sales compared with larger firms.
Uncertainty quantification for high frequency waves

Field: Mathematics (Physical Sciences)

We consider high frequency waves satisfying the scalar wave equationwith highly oscillatory initial data. The speed of propagation of the mediumas well as the phase and amplitude of the initial data is assumed to beuncertain, described by a finite number of independent random variables withknown probability distributions. We introduce quantities of interest (QoIs)aslocal averages of the squared modulus of the wave solution, or itsderivatives.The regularity of these QoIs in terms of the input random parameters and thewavelength is important for uncertainty quantification methods based oninterpolation in the stochastic space. In particular, the size of thederivativesshould be bounded and independent of the wavelength. In the contributedpapers, we show that the QoIs indeed have this property, despite the highlyoscillatory character of the waves.
In Roofs, Walls and Towers

Field: Arts and Humanities (Social Sciences)

This article deals with prehistoric stone objects called ‘thunderstones,’ which in the Middle Ages through modern times wereoften placed at the border points of houses and farm buildings (e.g., roofs, chimneys, walls, thresholds), as well as in town walls and other defence walls. It should be assumed that they were used as a magical means to protect areas considered to be controlled by humans (orbis interior) from threats posed by the outside world (orbis exterior). The clearly marked repetition of the same types of places in which these prehistoric stone objects were deposited (in areas places inhabited and used by humans) in many European regions indicates that this was a chronologically and territorially widespread phenomenon.
Wideband noise cancelling balun LNA with feedback biasing

Field: Engineering (Physical Sciences)

In this paper we present a balun low noise amplifier (LNA) in which the noise figure (NF) and power consumption are reduced by using a feedback biasing structure. The circuit is based on a conventional wideband balun LNA with noise cancellation. We propose to replace the typical current source of the CG stage by a transistor that establishes a feedback loop in that stage. This adds a degree of freedom which can be used to vary the CG transistor's transconductance, making it different from the typical value of 20 mS. Thus. we can increase the ratio between the gm of the CG and CS stages, which reduces the LNA NF, area, and power consumption, when compared with conventional circuits. Simulation results, with 65 nm CMOS transistors at 1.2 V supply, show that the LNA bandwidth is 3.4 GHz, the voltage gain is 21.8 dB, and the NF is less than 2.5 dB, with IIP3 above -5 dBm. The power dissipation is 4.3 mW. Another design, concerning linearity, has 18.6 dB voltage gain, NF below 2.9 dB and IIP3 above +3 dBm, over a 5 GHz bandwidth, with power consumption of 8.5 mW.
A tire contact solution technique

Field: Engineering (Physical Sciences)

An efficient method for calculating the contact boundary and interfacial pressure distribution was developed. This solution technique utilizes the discrete Fourier transform to establish an influence coefficient matrix for the portion of the pressurized tire surface that may be in the contact region. This matrix is used in a linear algebra algorithm to determine the contact boundary and the array of forces within the boundary that are necessary to hold the tire in equilibrium against a specified contact surface. The algorithm also determines the normal and tangential displacements of those points on the tire surface that are included in the influence coefficient matrix. Displacements within and outside the contact region are calculated. The solution technique is implemented with a finite-element tire model that is based on orthotropic, nonlinear shell of revolution elements which can respond to nonaxisymmetric loads. A sample contact solution is presented.
Stoffaustausch‐Maschinen. Chancen für den Gerätebau und die stoffwandelnde Industrie

Field: Chemical Engineering (Physical Sciences)

Abstract Mass transfer machines – opportunities for equipment construction and material conversion industries . The material conversion industry has one of the highest energy turnovers of all branches of industry. Modern mass production was possible only by switching to a continuous mode of operation. The large mass flows require use of a very wide range of process engineering machinery. In the first stage of machine deployment, conveying machines were introduced, i.e. pumps and compressors. In the second stage, numerous kinds of material transforming machines made their entry in the production process (e.g. in mechanical and biological process engineering). Material transforming machines are meanwhile to be found even in the area of heat transfer (Ljungström regenerator) and chemical engineering (stirred and extruding reactors). However, in spite of these introductory successes, the extensive fields of heat and mass transfer and reaction engineering still have to be conquered by appropriate machines. The trend of developments is unequivocal: the future belongs to material transforming machines. Such machines permit economic manufacture of mass products in comparatively small plants. These machines will help us to halt the trend to large scale plant and to replace them by smaller‐volume plant. The fundamental properties of the machines are presented in detail and examined in the case of two examples.
EP238 Assessing the Learning Curve in Hip Arthroscopy: A Prospective Case Series Analysis of Operative Efficiency Over Time

Field: Medicine (Health Sciences)

Abstract Background Hip arthroscopy remains a technically demanding procedure with a substantial learning curve. Developing surgical proficiency through increased caseload is critical for optimizing efficiency and refining training programs. The purpose of this study was to evaluate a single surgeon’s initial learning curve of hip arthroscopy cases based on operative efficiency. Methods All hip arthroscopies performed by a single hip preservation fellowship-trained surgeon were included, beginning with the surgeon’s first case as an attending. Prospective data collection was performed including total operating time, traction time, time to perform femoroplasty, and time to perform capsular closure. A generalized linear model using gamma distribution was employed due to the non-normal distribution of data. Regression analysis was used to determine changes in procedural times per case, and p-values were calculated to assess statistical significance, with a threshold of p &lt; 0.05 indicating statistical significance. Results A total of 17 hip arthroscopy procedures were included, performed from October 2024 to April 2025. Mean operating time was 225 ± 85 minutes, mean traction time was 125 ± 68 minutes, mean femoroplasty time was 51 ± 23 minutes, and mean capsular closure time was 25 ± 17 minutes. Overall, there was a 3.2% (p = 0.061) decrease in total operating time, a 5.2% (p = 0.025) reduction in total traction time, a 0.36% (p = 0.88) reduction in femoroplasty time, and a 4.1% (p = 0.12) reduction in capsular closure time per case. Discussion During the initial hip arthroscopy learning curve, there is improved operative efficiency over time with regard to all aspects of the procedure with a statistically significant reduction in traction time. Although the small sample size of this study limits definitive conclusions, these early trends underscore the importance of experience in enhancing procedural efficiency and support the use of operative metrics in surgical training programs.
An Exploration of the Use of Functional Behavior Assessment and Noncontingent Reinforcement on Disruptive Behavior in Middle School General Education Classrooms

Field: Psychology (Social Sciences)

Teachers sometimes experience problems with disruptive behavior in their classrooms. These aberrant and socially mediated behaviors can be difficult for teachers to manage without the proper research-based skills and training. This project explored the effects of training general education classroom teachers to conduct a functional behavior assessment and deliver noncontingent reinforcement (NCR) for disruptive classroom behavior(s). Participants included four middle school general education teachers and four students who have been identified by each teacher as exhibiting disruptive behavior(s). Procedures included four hrs of teacher training on conducting functional behavior assessments and delivering NCR followed by a post-training questionnaire and rubric based role play to determine the readiness of the teacher to proceed with implementation. Pre-intervention data on the target students was collected by the researcher while the teacher conducted class as usual. Next, the intervention was initiated and data were 4 collected by the researcher and an independent observer trained by the researcher to determine the impact of the intervention on student behavior. The NCR intervention produced decreased disruptive behavior(s) for all student participants. The results obtained indicate training teachers to conduct functional behavior assessments and implement NCR interventions for reducing disruptive behavior(s) has potential to be a viable tool.

Pre‐implantation Pregnancy Disruption in Female Meadow Voles Microtus pennsylvanicus (Rodentia: Muridae): Male Competition or Female Mate Choice?

Field: Agricultural and Biological Sciences (Life Sciences)

Abstract I investigated alternative hypotheses concerning the functions of pre‐implantation male‐induced pregnancy disruption in meadow voles. Disruptions may be viewed as: 1. Postcopulatory male competition; 2. A mechanism for postcopulatory mate choice by females; and 3. A means of benefitting females by terminating investment in litters that may be harmed by new males. Female voles were paired with a second male 3 d after mating with their first mate. Behavioural interactions between the female and each male were compared for females that disrupted or retained the pregnancy sired by the first male. Whether they were the females' first or second mates, males siring litters showed similar high levels of approach and moderately high aggression, behaviour that differed from the females' other mates. Disrupted females huddled sooner with their second mates than females that retained their original pregnancies, and females tended to approach males that approached them. These results suggest that females influence whether a disruption occurs by the amount of contact they initiate with the second male, and thus pregnancy disruption may facilitate postcopulatory mate choice by females. This pre‐implantation disruption did not enhance female reproductive success: pup survival was the same whether or not a disruption occurred, and males living with pups they had sired (after a disruption) spent as much time with them as males with unrelated pups (females did not disrupt).
China-US Relations: The Past as Looking Glass

Field: Social Sciences (Social Sciences)

Since the founding of the People's Republic of China in 1949, interaction between China and the United States has assumed three different patterns, each carrying a distinct set of structural and interactive characteristics. During the period from 1949 to 1970, the basic feature of the Sino-US relationship was confrontation. In the following two decades, the two countries became strategic partners. Then the end of the Cold War and the reform-driven development of China gave rise to another round of major policy adjustments. The product was the emergence of still another kind of relationship, characterized by partial cooperation and partial friction. The primary objective of the paper is to analyze the major conditions that have shaped these patterns and their particular features in order to achieve a measure of understanding of the future development of US-China relations. Empirical evidence suggests that in the case of China and the United States, the following four major factors are relevant for explaining the past and present, namely the perceived interests of the two countries, the structure of their mutual dependence, the agency factor in power use, and their preconditions. Therefore, the analysis of the paper will focus on the impact of these four factors.

[On pre-requirements to the use of audio-visual techniques in deviant children. Thoughts from the psychoanalytical treatment of a thirteen months aged child (author's transl)].

Field: Psychology (Social Sciences)

This paper deals with the analytical cure of a child between 13 and 21 months and hospitalized since birth. In a first phase, one can see the start of a relationship, then the objectal relationship to primary objects: on the one hand the object food and on the other hand the therapist within the transfert. These two objects, impossible in the reality dimension from the start, are progressively characterized by "neantisation", which can reach symbolic tone. A scene in front of the picture of a child on knees of a nurse progressively introduces Nadia to the third register: the imagery one. Her behaviour is exemplary during the 17 scences on the mirror, during which she can progressively assume the image of her unified body under the view of the other, in demonstrating that she can only do it by symbolizing primary objects, in particular "to drink nothing". The symbolisation acquired at the oral level permits to verbalise on the same mode her relationship to the anal object, i.e. on the non destructive symbolic mode. This treatment raises the question of the use of audio-visual techniques for psychotic and autistic subjects, and recuses the pedagogic use of image for such subjects, taking into account the primary importance of symbolic function on imagery function demonstrated in this paper. This is a prerequisite for any research in the field of audiovisual techniques with psychotics.
Milk flow traits in Mediterranean Italian Buffaloes

Field: Veterinary (Health Sciences)

The aim of this study was to analyze the milk flow pattern in Italian Mediterranean Buffaloes in relation to parity and oxytocin administration. A total of 330 milk flow recorders were collected during morning and evening milkings by using an electronic milk flow meters (Lactocorder®). Milk flow curves were examined and subject were divided according milk flow pattern in: normal pattern, bimodal pattern and “double pattern”. Data were analysed by using ANOVA and Chi square test. Total milk yield per milking was significantly higher (P<0.01) in pluriparous and consistent with the average DIM of 205 days. No differences in milk yield and maximum milk flow were found between the oxytocin groups while both parameters were higher in bimodal and double pattern groups compared to normal milk flow pattern. Lag time was higher (P<0.01) in oxytocin treated group and in normal vs the other two pattern groups. Length of main milking phase was higher in pluriparous, oxytocin treated group (P<0.01) and in bimodal vs the normal one (P<0.05) while double pattern showed the highest value (P<0.01). Percentage of bimodal milk flow was 13.7% while a double flow pattern was 12.4%. A higher percentage of double pattern was found in oxytocin treated buffaloes vs normal and bimodal ones (18.1% vs 8.1% and 7.5% respectively; P< 0.05) and in pluriparous vs primiparous (74.4% vs 25.6%; P< 0.05).
