Disparate data integration case for connected factories using timestamps
Get PDFManufacturing data integration of machine, process, and sensor data from the shop floor remains an important issue to achieve the anticipated business value of fully connected factories. Integrated manufacturing data has been a hallmark of Industry 4.0 initiatives, because integrated data precipitates better decision-making for cost, schedule, and system optimizations. In this paper, we extend work on optimizing manufacturing costs, describing an algorithm using timestamps to integrate previously unassociated quality and test information, enabling us to better identify and eliminate redundant tests. Results are provided and discussed, and we suggest the approach described may be valuable for some types of heterogeneous manufacturing data integration where timestamps and event chronologies are available

Chemoprophylaxis after oncological resections
Get PDFBackgroundNational societies recommend extended-duration VTE chemoprophylaxis for up to 4 weeks following major oncologic resections with the literature demonstrating an incidence of approximately 2% for symptomatic VTE. Despite this, patients are not routinely discharged on VTE chemoprophylaxis at our institution. MethodsA retrospective chart review was performed for major abdominal oncologic resections, including esophagectomy, at an academic community cancer center between 2016 and 2021. The primary outcome was the incidence of clinically evident VTE events (defined as lower extremity deep vein thrombosis (LE DVT) or pulmonary embolism (PE)) within 30 days of discharge and diagnosed on re-presentation. Exclusion criteria included in-hospital mortality, in-hospital VTE, or discharge on anti-coagulation. Comparisons were performed using Fisher’s Exact and Mann-Whitney test.ResultsAfter exclusion criteria were applied, 458 patients were identified. A total of 6 (1.3%) patients developed symptomatic VTEs, 5 (1.1%) PEs and 3 (0.7%) DVTs. No procedural interventions were required. On average, patients re-presented 14.3 (±8.4) days after discharge. There were no mortalities within 30 days of discharge. Intraoperatively, estimated blood loss in VTE group was decreased (150 vs 88 mL, p=0.01), while length of inpatient hospitalization (6.5 vs 10 days, p=0.05) was increased. Type of operation demonstrated an increased proportion of esophagectomy (9.6% vs 16.7%, p=0.57), palliative bypass (8.1% vs 33.3%, p=0.08) and small bowel resection (7.9% vs 33.3%, p=0.08) in the VTE group. Conclusion The percentage of symptomatic VTEs in our patients was not higher then reported averages despite no patient receiving chemoprophylaxis. Questions remain as to which subset of patients would benefit from chemoprophylaxis after major abdominal oncologic resection. Further investigation into long term effects of asymptomatic DVT should be undertaken.
Issues in resolution and build size scaling of additive manufacturing technologies
Get PDFIn this review, scaling issues in additive manufacturing (AM) processes are discussed based on multiple factors. Scaling issues arise mainly due to design and control of the AM system and also while attempting to achieve desired accuracy. Based on current AM systems available commercially, we identified scaling issues that can potentially challenge the build feasibility and accuracy while moving in geometrical and build resolution length scales. Inherent limitations of multiple AM processes are discussed based on these aspects and challenges while implementing these technologies in multiple length scales are identified through this work. Potential remedies for such scaling issues are also presented based on current progressing research in AM.
Modelling and outdoor performance characterization of monocrystalline and polycrystalline silicon photovoltaic modules
Get PDFThis paper presents the modeling and outdoor performance of monocrystalline silicon (m-Si) and polycrystalline silicon (p-Si) Photovoltaic (PV) modules. The I – V and P – V characteristics curves obtained by simulation and from outdoor experiments, were used to extract electrical parameters such as open-circuit voltage, short circuit current, maximum current, and maximum voltage. Parameters acquired were further used to compute the maximum power output, fill factor, and conversion efficiency of PV modules. The simulation results obtained were in agreement with the manufacturer’s datasheet value while experimental results showed a slight deviation from Standard Test Condition (STC) values. The effects of solar irradiance, module temperature, quality, and series resistance on the performance of PV modules were considered. It was observed that as solar irradiance increased the performance of PV modules improved, whereas the increase of other parameters such as module temperature, series resistance, and diode ideality factor declined the performance of PV modules.@font-face {font-family:"Cambria Math"; panose-1:2 4 5 3 5 4 6 3 2 4; mso-font-charset:0; mso-generic-font-family:roman; mso-font-pitch:variable; mso-font-signature:-536870145 1107305727 0 0 415 0;}@font-face {font-family:Calibri; panose-1:2 15 5 2 2 2 4 3 2 4; mso-font-charset:0; mso-generic-font-family:swiss; mso-font-pitch:variable; mso-font-signature:-536859905 -1073697537 9 0 511 0;}p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-unhide:no; mso-style-qformat:yes; mso-style-parent:""; margin:0cm; margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:12.0pt; font-family:"Calibri",sans-serif; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:Calibri; mso-fareast-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi; mso-ansi-language:EN-GB;}.MsoChpDefault {mso-style-type:export-only; mso-default-props:yes; font-family:"Calibri",sans-serif; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:Calibri; mso-fareast-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi; mso-ansi-language:EN-GB;}div.WordSection1 {page:WordSection1;

Influence of physical exercise practice against SARS-CoV-2 (COVID-19) infection: narrative review
Get PDFAs a protective measure against the Covid-19 virus, the world health organization strongly recommended social isolation. Because of a lower offer of physical exercise, there was an increase in the number of physical inactivity, poor diet, and psychological disorders. In this sense, this literature review aims to address how the practice of physical exercise is important to protect the metabolic and psychological health of the population. During forced isolation, it was possible to observe an increase in sedentary lifestyle and poor diet. As an outcome, possible damage to the population's mental health was also identified. In contrast, it was observed that individuals who practiced physical exercise, managed to mitigate both metabolic and psychological damage. Ahead, it was also possible to observe that this practice significantly contributed to the individuals' immune system, which can collaborate with the organism in the fight against possible contamination. Given this, the objective of this review was to identify possible implications of physical exercise on psychological and immunological aspects in coping with Covid-19. Important physiological effects of exercise were found, such as elevation of the brain-derived neurotrophic factor (BDNF), which has beneficial effects in controlling depression and cognitive performance; the control of obesity through specific training methodologies can collaborate to control pro-inflammatory cytokines and increase mitochondrial function and immune system. In addition, there are up to 205 symptoms after infection by SARS-CoV2 and physical exercise can be a great ally for recovery. Therefore, it is believed that regular exercise has positive effects before, over, and post-pandemic
Analysis of the metabolic and hormonal effects of Krav Maga physical training
Get PDFAbstract Aim: The aim of this study is to evaluate the metabolic aspects and cortisol during the practice of this modality.Methods A sample of 30 volunteers was distributed into a group of beginners who had never practiced the modality (GI; n = 15). The experimental group consisted of veteran Krav Maga practitioners (GV; n = 15). Both participated in training for a period of 16 weeks and samples were collected in week 1, 8 and 16 (S1, S8 and S16, respectively), always at the same time. Pre- and post-training glycemic behavior, fasting glucose, lipid profile (total cholesterol, HDL cholesterol, LDL, VLDL, triglycerides), basal lactate and cortisol were measured.Results: The variables total cholesterol, triglycerides, HDL, LDL and cortisol did not present significant differences with the training time and between GI and GV. On the other hand, fasting glucose, post-training glucose and VLDL showed a significant effect (p = 0.003; p < 0.001 and p < 0.001, respectively) related to training time, however, there was no difference between GI and GV Pre-training glucose increased with training time (p < 0.001) and was higher for GV.Conclusion: The practice of Krav Maga for 16 weeks promotes changes related to training time for fasting glucose and pre- and post-training glucose, along with VLD
Proximate composition, mineral content, cooking quality, and sensory properties of Kalinga mix and Moringa noodles
Get PDFThe main objective of this study is to develop an acceptable and nutrient-dense noodles from KALINGA mix and moringa. Materials for making the noodles such as KALINGA mix (rice, sesame seeds, mung bean), bread flour, and moringa powder were purchased at the local market of Los Baños, Laguna. Malnutrition in the Philippines remains to be a serious health problem, especially to low-income areas.Its challenges and enormity in the country require new research and innovations that are accessible and will make use of native resources to achieve better health and nutrition for the community. Hence an attempt to develop an acceptable and nutrient-dense noodles incorporating KALINGA mix and moringa.The noodles were prepared with different ratios of KALINGA mix (30g, 20g, 10g) and flour (70g, 80g, 90g, 100g). All samples were then added with 5g of moringa. The results of the study showed that all the cooking losses of the samples were below the technologically acceptable limit (≤8%). In the overall acceptability, the sample with 30g KALINGA has the highest mean score of 7.125 (like moderately).The proximate composition showed that the highest moisture content (7.64%), and crude protein (10.86%) were found in 10g KALINGA, whereas crude fat (15.57%), and ash (1.0%) were the highest in 30g KALINGA, crude fiber (0.73%) and NFE (69.77%) were highest in the control sample. For the mineral content, the control sample was highest in calcium (125 mg/100g), and iron (7.4mg/100g) while the 30g KALINGA had the lowest in both. Zinc is the same in all samples (1.2 mg/100g). In conclusion, the sample with 30g KALINGA was good in terms of its cooking quality, overall acceptability, and proximate composition. The control however was better in its calcium, and iron content
Comparison between laser-cutting or molded polyoxanone thread in facial lifting
Get PDFThere is no literature comparing the effectiveness of laser-cutting or molded barbed polydioxanone (PDO) threads when used in protocols for facial lifting. The objective of this study was to compare the efficiency of laser-cutting (n=10) or molded (n=15) threads in facial lifting procedures. Adverse events, quality of treatments, and self-perception facial improvement were investigated immediately and after 90 days of the clinical procedures. Data pointed that the most prevalent adverse events reported by the patients, for both threads, were pain and sensation of skin traction at the intervention sites (56%). According to the Numeric Visual Scale (NVS), the molded thread received score 10 in 42.8% of the patients. It was observed more reports of major (n=32) and noticeable (n=46) facial aesthetic improvement by patients who received laser-cutting threads. The results suggest that both, laser-cutting or molded threads, cause few adverse events, allow good acceptance by patients, and permit to treat successfully different facial areas.
