Brake squeal analysis in time domain using ABAQUS - Finite element simulation of brake squeal for passenger cars

Field: Engineering (Physical Sciences)

One of the main quality concerns of car manufacturers is brake squeal. There are two CAE (Complex Aided Engineering) method for prediction of brake squeal, CEA (Complex Eigenvalue Analysis) and TDA (Transient Dynamic Analysis). However, CEA method is a quite usual tool to evaluate brake squeal propensity despite its intrinsic overestimation of any system instabilities. In contrast, TDA provides a reduced number of predicted instabilities, but it is too time consuming for complete FE models. The purpose of this thesis is the comparison of TDA with CEA to identify brake squeal frequencies. The finite element model of studied brake system consists of a brake disc, and pair of brake pads (friction material and backplate). Using the CEA method, brake squeal frequencies are identified by coalescence modes and calculation of Negative Damping Ratio (NDR) for various pressure and friction coefficient. As a comparison with CEA, TDA is performed by use of dynamic explicit solver to extract the variation of amplitude at a node on the brake disc friction surface over time. The frequency response function of a node on brake disc can be calculated by Discrete Fourier Transform (DFT), the frequencies correspond to the peaks of frequency response function can be considered as a representative of brake squeal frequency.
The comparison of TDA and CEA reveals that even though five modes are introduced by NDR criteria for brake squeal onset, merely two of them are detected by TDA. Taking account of CEA overestimation about unstable modes, it can be concluded that the frequency response derived from the transient response can be a reliable method to represent the system instability. In addition, regarding TDA results brake squeal might happen in an unstable mode even with low value of real part as well as NDR.

Maternal resolution of loss and abuse: Associations with adjustment to the transition to parenthood

Field: Psychology (Social Sciences)

Abstract This study examined relationships between mothers' resolution of past loss and abuse and their adjustment to the transition to parenthood. Three groups of mothers were compared: 1) those who were unresolved with respect to loss or abuse (Unresolved Loss/Abuse), 2) those who had experienced loss or abuse, but were considered resolved (Resolved Loss/Abuse), and 3) those who had not experienced loss or abuse (No Loss/Abuse). Mothers in the Resolved Loss/Abuse group reported more negative perceptions of the transition to parenthood than did mothers in the No Loss/Abuse group, which may reflect a greater awareness of negative emotions and a greater ability to communicate openly about them. Although mothers who have experienced loss or abuse and appear to have resolved these experiences may be at risk for distress during the transition to parenthood, they do not appear to be at risk for insensitive care giving. Unresolved loss, however, was associated with less sensitive care giving. The findings of this study highlight the importance of examining current state of mind regarding past experiences when investigating relationships between childhood loss and abuse and adjustment to subsequent life transitions. ©2004 Michigan Association for Infant Mental Health.
Surveillance of drug therapy

Field: Health Professions (Health Sciences)

Early last year the state of the art of adverse drug reaction reporting was assessed inThe Journal,1found severely wanting, and suggestions voiced for its improvement. In this issue, the two communications by Jick, Slone, and associates from the Lemuel Shattuck Hospital, Boston, report two of the early fruits of a carefully conceived in-hospital drug surveillance program. This is a study of considerable depth and sophistication. It employs full-time paramedical personnel and insists on putting into the computer complete data on all drugs received by patients, as well as much potentially meaningful clinical data, all of which seems adequately and carefully monitored and validated under close nursing and medical supervision. The profile data covers many significant features in each patient, including genetic markers, such as the ABO, MNSs, and other blood groups, when available. By this means, a data bank has resulted which is continually expanding and which
Use of Colony-Stimulating Factors in Patients With Systemic Lupus Erythematosus

Field: Medicine (Health Sciences)

Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease that commonly manifests as cutaneous rashes, renal disease, gastrointestinal dysfunction, and cytopenia. Hematological anomalies are frequently associated with drug-induced toxicity in SLE patients. Colony-stimulating factors have been used to treat drug-induced cytopenia in past case reports; however, evidence suggests that colony-stimulating factors can exacerbate autoimmune disorders, including SLE. This case report presents two patients with SLE exacerbations after colony-stimulating factor administration. The first case is a young male with SLE who developed pancytopenia with a white blood cell count (WBC) of 1 × 10 9 cells/L. The patient was administered filgrastim during his initial admission and presented to the hospital 2 days after discharge in cardiac arrest with a WBC of 66.7 × 10 9 cells/L. The second case is a 49-year-old female with SLE who was administered sargramostim in response to a WBC count of 9 × 10 9 cells/L. The patient experienced a drastic increase in WBC followed by a cardiac arrest. These cases highlight the need for more research regarding the safe use of colony-stimulating factors in SLE patients.

Understanding the experiences of virtual race participants through the lens of mindfulness theory

Field: Social Sciences (Social Sciences)

The development of digital technologies and innovations has contributed, in part, to the rise of virtual races. As a type of active leisure event, virtual races have the potential to overcome geographic constraints and attract more participants. To further our understanding of participants’ virtual race experiences, we adopted mindfulness theory to examine components that contributed to participants reporting a mindful experience or a mindless experience, respectively. Qualitative data were collected via photo-elicitation interviews with 20 informants who completed the 2020 Illinois Marathon Virtual Race in the United States. Findings showed that components that led to informants reporting a mindful experience included: 1) a self-created connection to place, 2) bounded creativity, and 3) an adaptive mindset, whilst components that led to informants reporting a mindless experience included 1) the absence of event formalities and 2) anchoring bias. Based on these findings, we developed a model of mindful/mindless virtual race experiences. Implications for active leisure event literature and mindfulness theory were discussed, along with practical recommendations for how event managers and participants can co-create a mindful virtual race experience.
Stiffness of an EVA glove: objective evaluation and testing procedures

Field: Engineering (Physical Sciences)

Hand fatigue is one of the major problems of astronauts during Extravehicular Activity (EVA), due to the stiffness of the space suit, in particular of the glove. In order to evaluate the stiffness of EVA gloves, different methods have been proposed in the past, mainly focused on the effects of wearing an EVA glove on hand performance when executing test protocols. In this paper, an objective method for the evaluation of the stiffness of EVA gloves is proposed, by means of a tendon-actuated finger probe. The finger probe is equipped with accelerometers, to measure the angles of its phalanges. These are actuated by applying different torques using the finger probe tendons. The EVA glove is tested in both pressurized and non pressurized conditions, thanks to a hypobaric glove box. An Orlan-DM EVA glove is tested and stiffness results are presented. This setup can be used for different kinds of gloves, not necessarily for EVA application, and allows direct, numerical measurement of their stiffness
Sensitive and specific identification by polymerase chain reaction ofEimeria tenellaandEimeria maxima, important protozoan pathogens in laboratory avian facilities

Field: Veterinary (Health Sciences)

Eimeria tenella and Eimeria maxima are important pathogens causing intracellular protozoa infections in laboratory avian animals and are known to affect experimental results obtained from contaminated animals. This study aimed to find a fast, sensitive, and efficient protocol for the molecular identification of E. tenella and E. maxima in experimental samples using chickens as laboratory avian animals. DNA was extracted from fecal samples collected from chickens and polymerase chain reaction (PCR) analysis was employed to detect E. tenella and E. maxima from the extracted DNA. The target nucleic acid fragments were specifically amplified by PCR. Feces secreting E. tenella and E. maxima were detected by a positive PCR reaction. In this study, we were able to successfully detect E. tenella and E. maxima using the molecular diagnostic method of PCR. As such, we recommended PCR for monitoring E. tenella and E. maxima in laboratory avian facilities.
The Aesthetic of Minahasa Traditional House

Field: Arts and Humanities (Social Sciences)

Traditional Minahasa houses are residential buildings created by the Minahasa tribes. The fact that the Traditional Minahasa House (RTM) is still used as typical idea of Minahasa people in making their living quarters proving that Minahasa people are proud of their tradition. The continued appreciation indicates there are resistance value in Minahasa Traditional House. This paper study the condition between Minahasa community with RTM through the study of RTM aesthetics. Aesthetics exists both in architecture and human being. Besides, according to Walker (2000) in his theory of 'desire', aesthetics is one of the fundamental elements of human beings that able to make changes by time passed. By using the architectural aesthetics approach of Ralf Weber (1995), it appears that RTM has aesthetic value resistance.

Preparation of Highly Stable and Electrochemically Active Three‐dimensional Interconnected Graphene Frameworks from Jute Sticks

Field: Materials Science (Physical Sciences)

Abstract Over the past few years, the environmentally friendly synthesis of nanomaterials, including graphene using green chemistry, has attracted tremendous attention due to its easy handling, low cost, and biocompatibility. Here we demonstrate a facile and efficient green synthesis route for producing highly stable and electrochemically active three‐dimensional interconnected graphene frameworks (3DIGF) from jute sticks. Initially, jute sticks derived three‐dimensional amorphous activated carbon nanosheets (3DAACNs) were prepared at low temperatures (i. e., 850 °C) in an inert environment. The resultant 3DAACNs were then heat treated at a high temperature (i. e., 2700 °C) under an inert environment, resulting in 3DIGF. The prepared carbonaceous materials were fully characterized, and various experimental techniques confirmed the preparation of 3DIGF. The prepared 3DIGF shows a highly stable nature in thermal and chemical environments and demonstrates a highly dynamic nature for the electrooxidation of sulfide. This study could be considered a vital contribution towards the economic and simple approach for preparing 3DIGF from biomass.
Measurement Invariance Widely Holds for the Yale-Brown Obsessive Compulsive Scale

Field: Psychology (Social Sciences)

The clinician-rated Yale-Brown Obsessive Compulsive Scale (Y-BOCS) is a widely used assessment tool for obsessive-compulsive disorder (OCD). However, the measurement invariance (MI) properties of the Y-BOCS, a prerequisite for group or time point comparisons in clinical research, have received little attention in previous studies. In this study, we aim to comprehensively investigate the factor structure and MI of the Y-BOCS severity rating and its symptom checklist, utilizing a large sample of OCD patients ( N = 1,066). Our analysis considers various MI covariates, including time (pre- and post-therapy), severity, comorbidity, previous treatments, and demographics. Overall, the majority of tests conducted on the Y-BOCS severity rating and its symptom checklist revealed no substantial issues with MI, reinforcing the validity of the Y-BOCS for comparative clinical research. Specifically, we discuss a three-factor model for the severity rating, contrasting with a two-factor model for obsessions and compulsions when excluding the resistance items. Notably, our findings underscore the advantages and validity of employing latent factors rather than sum scores to model OCD severity and symptoms.

Effect of trap clustering on Brownian particle trapping rate

Field: Physics and Astronomy (Physical Sciences)

Brownian particle survival is studied in the case where traps are gathered in clusters. If the number of traps n in a cluster is small, the trap clustering is only manifested at the final stage of the process. In the opposite limit, the clusters are perfectly absorbing and trapping proceeds considerably slower than that by noncorrelated traps from the very beginning. We treat the intermediate case, where n is neither small nor large, and present an approximate expression for the rate constant that connects the two limiting cases. The results are in agreement with computer simulations.

Nellix Endovascular aneurysm-sealing System: A single-center Experience and Review of Current Evidence

Field: Medicine (Health Sciences)

Aims: We report the 6-year results of our use of the Nellix® endovascular aneurysm sealing system. Materials & methods: This is a retrospective review of patients we treated from 2013 to 2019. The outcomes described include technical success rate, mortality, all procedure-related complications, reinterventions, open surgical conversion and secondary sac rupture. Results & conclusions: A total of 68 patients were treated. Mortality was 2.9%. Secondary interventions were carried out for distal embolization (3), stent occlusion (1), pseudoaneurysm (1) and endoleak (5). Open surgical conversion was required in 6.4% of cases. Medium- and long-term complications of EVAS occurred more frequently than expected. Because the durability of endovascular aneurysm sealing is questionable, strict postoperative surveillance of Nellix is crucial to identify features of failure.
Experimental investigation on Newtonian Behaviour and Viscosity of TiO2/PVE nanolubricants for application in Refrigeration System

Field: Chemical Engineering (Physical Sciences)

The flow characteristics are highly dependent to viscosity of the fluid. For nanolubricant with different concentration, viscosity change is one of important parameter to be measured to evaluate its functional ability as lubricant. This paper studies about the effect of TiO2 nanoparticle in poly vinyl ether (PVE) at different concentration and temperature. Nanolubricant with volume concentration between 0.01% to 0.1% prepared using two-step method and tested at 40 C, 60 C, and 80 C temperature by using digital rheometer. Beforehand, the colloidal suspension fluid was observed by visual and zeta potential measurement to ensure its stability. The fluid Newtonian behaviour was identified for shear rate up to 1000 rpm. The results shown that dynamic viscosity of 0.01% TiO2/PVE nanolubricant had decreased up to 11% for all measured temperature. For other samples, viscosity increment does not reach more than 1.5% compared to pure PVE oil. It also observed that viscosity increment by the increasing of volume concentration, but it decreases by the increment of temperature. The finding in this study confirms that viscosity of TiO2/PVE nanolubricant effected by both temperature and volume concentration to opposite behaviour.

Club’s visitors are offered group aerobic classes aimed at weight loss, training of the cardiovascular and respiratory systems. For a long time, group programs have been popular among clients of fitness clubs and fitness studios.
What can we learn from young adolescents’ perceptions about the teaching of reading?

Field: Social Sciences (Social Sciences)

Young adolescent students are at a critical time in their schooling. Once they embark into secondary schooling their prospects of achieving well across a range of curriculum subjects can often depend on their ability to critically analyse and understand a range of text types. This article focuses on 34 young adolescent students’ views about learning to read. By better understanding what works for these young adolescents, teachers and educators can further enhance effective learning environments for students’ reading development. The research study explored the views of 11 to 13 year old students who came from six schools. Overall, the school populations had a higher representation of students from diverse cultural backgrounds, than in the majority of New Zealand schools. Five of the schools were in low to mid socio-economic areas and one school was in a higher socio-economic area. The small group interviews with the students found that they appreciated teachers using explicit teaching strategies to guide their learning during reading. Many of the students valued learning to reading as they perceived it as an essential skill for their long-term well-being and career opportunities. It was apparent that these young adolescents valued learning to read in a safe and respectful learning environment. Irrespective of socio-economic or cultural backgrounds, the students viewed learning as a serious matter. Learning to effectively read and comprehend was viewed as a foundation to their success in the future.
