No full textMass Production Processes
No full textIt is always hard to set manufacturing systems to produce large quantities of standardized parts. Controlling these mass production lines needs deep knowledge, hard experience, and the required related tools as well. The use of modern methods and techniques to produce a large quantity of products within productive manufacturing processes provides improvements in manufacturing costs and product quality. In order to serve these purposes, this book aims to reflect on the advanced manufacturing systems of different alloys in production with related components and automation technologies. Additionally, it focuses on mass production processes designed according to Industry 4.0 considering different kinds of quality and improvement works in mass production systems for high productive and sustainable manufacturing. This book may be interesting to researchers, industrial employees, or any other partners who work for better quality manufacturing at any stage of the mass production processes
HIGH SCHOOL STUDENTS’ READINESS FOR DISTANCE LEARNING
No full textThe purpose of this study was to determine high school students for distance learning. Mainly due to the study a multidimensional instrument for high students’ readiness for distance learning (HRD) developed and validated. The study adopted qualitative research method based on quantitative data. The participants of the study comprised 191 high school students who were selected using randomly sampling model. The data were collected via readiness for distance learning scale (HRD) and analyzed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) to establish the construct validity of the HRD model. In addition, a series of one-way ANOVA were conducted to investigate the effect of demographic variables on readiness of distance learning. Through confirmatory factor analysis, HRD was validated in three dimensions: communication, access and motivation. In this study, high school students’ mean scores in three dimensions are all higher than the theoretical mean of 3, ranging from 3.60 to 4.37 on a 5-point scale as X̄= 40.64 (SS=8.80).This finding means that the current study’s sample of high school students has the highest readiness in the dimension of access X̄=16.98 (SS=4.64), followed by motivation X̄=12.86 (SS=4.66); communication X̄=10.79 (SS=2.45. The significant differences were observed that high school students are those who study at 9. grade had greater readiness than high school students are those who study at 11. grade in high schools whereas high school students are those who study at 11. grade in high schools had greater readiness than high school students are those who study at 10. and 12. grade in high schools according to means score of HDR. It was also found out that perception of students’ self-confidence while using computer caused significant statistical differences in three dimensions of HRD; the students who had higher level (very good, good) of self-confident while using computer exhibited significantly greater readiness than those who had lower level of self-confident while using confidence. Meanwhile, high school students are those who had study habit reached greater point from HDR scale than high school students who had not study habit (t (188) = 5.29, p = .00,d=.08)
Production and quality assessment of functional crackers based on fruit seed oils
No full textCrackers are popular bakery products known for their crunchy texture and long shelf life. Typically made from leavened or unleavened dough with wheat flour, oil, water, and additives, crackers have undergone recipe enhancements to improve sensory and nutritional profiles. While many studies explore cracker and biscuit formulations, fruit seed oils remain underexplored. Fruit seeds, often discarded as waste, are rich in essential fatty acids, amino acids, and micronutrients. Oils from seeds such as grape, pomegranate, rosehip, and apricot have gained attention for their health benefits, which presents an opportunity for innovation in bakery products. This study evaluated the potential of incorporating various fruit seed oils (pomegranate, apricot kernel, grape, fig, and rosehip) into cracker formulations. Crackers were assessed for physicochemical properties, antioxidant activity, mineral content, texture, and sensory attributes, with sunflower oil as the control. Results showed that the addition of fruit seed oils significantly influenced cracker properties. Crackers with apricot kernel oil had the highest ash content (2.29 ± 0.13%) and exhibited a more acidic character, as did those with grape seed oil. Moisture content decreased significantly when rosehip seed oil was used (P < 0.05). Grape seed oil yielded the highest water-holding capacity, while sunflower oil provided the highest oil-holding capacity. Crackers made with rosehip and apricot kernel oils demonstrated improved antioxidant properties. Using fruit seed oils not only enhances nutritional value (e.g. vitamins, minerals, antioxidants, and dietary fiber) but also reduces material waste, contributing to sustainability and better resource utilization. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024
The effectiveness of preemptive thoracic epidural analgesia in thoracic surgery
No full textakdogan, ali/0000-0001-7592-3844; Erturk, Engin/0000-0002-5864-1754Background. the aim of this study is to investigate the effectiveness of preemptive thoracic epidural analgesia (TEA) comparing conventional postoperative epidural analgesia on thoracotomy. Material and Methods. Forty-four patients were randomized in to two groups (preemptive: Group P, control: Group C). Epidural catheter was inserted in all patients preoperatively. in Group P, epidural analgesic solution was administered as a bolus before the surgical incision and was continued until the end of the surgery. Postoperative patient controlled epidural analgesia infusion pumps were prepared for all patients. Respiratory rates (RR) were recorded. Patient's analgesia was evaluated with visual analog scale at rest (VASr) and coughing (VASc). Number of patient's demands from the pump, pump's delivery, and additional analgesic requirement were also recorded. Results. RR in Group C was higher than in Group P at postoperative 1st and 2nd hours. Both VASr and VASc scores in Group P were lower than in Group C at postoperative 1st, 2nd, and 4th hours. Patient's demand and pump's delivery count for bolus dose in Group P were lower than in Group C in all measurement times. Total analgesic requirements on postoperative 1st and 24th hours in Group P were lower than in Group C. Conclusion. We consider that preemptive TEA may offer better analgesia after thoracotomy
Prediction of Response to Androgen Deprivation Therapy and Castration Resistance in Primary Metastatic Prostate Cancer
No full textPurpose: We tried to establish the predictive factors influencing the initial response, as well as its duration, and time to castration resistance (CR) for primary advanced prostate cancer (PC) with bone metastasis. Methods: We evaluated all patients initially receiving androgen deprivation therapy (ADT) for primary advanced PC with bone metastasis. A total of 982 patients with complete medical records available for analysis from 18 centers were included in this study. Age, initial PSA, Gleason score (GS) and extent of bone involvement (EBI) were recorded in a database. Results: Among all the patients, 896 (91.2%) responded to ADT initially. Pretreatment PSA and EBI were significant predictors in the multivariate model. Among the 659 patients who progressed into a CR state, the mean duration of response was 22.4 months. There was a significant correlation between the CR state and nadir PSA (nPSA) level and time to nPSA. Pretreatment PSA, EBI, GS, highest tumor volume in biopsy cores (%), number of positive biopsy cores, percent positive biopsy cores and time to nPSA were proven to be significant to predict a nPSA. Pretreatment PSA, GS and EBI were statistically significant predictors of PSA normalization in multivariate analysis. The limitation of the study depends on the retrospective design and a model was developed for low standardization as a result of using multicenter data. The patients enrolled in this study were from a relatively long period of time (1989-2008). Conclusions: The results of this study indicate that it is possible to predict the initial response to ADT by pretreatment PSA levels and EBI, while the duration of response can be reflected by a multitude of clinical factors including nPSA, TTnPSA, percent positive cores, biopsy GS and EBI.
