Rolling Bearings Fault Diagnosis under Variable Conditions Using RCMFE and Improved Support Vector Machine
Authors: Zhang Xin , Zhao Jian-min , Li Hai-ping , Yang Rui-feng , Teng Hong-zhi
Published: October 2020

As critical components, rolling bearings are widely used in a variety of rotating machinery. It is necessary to develop a suitable fault diagnosis method to prevent malfunctions and breakages of bearings during operation. However, the current methods for the fault diagnosis of rolling bearings are too cumbersome to be applied in practical engineering. In addition, the working condition of rolling bearings is generally tough, complex, and especially variable. These conditions cause fault diagnosis methods to be less effective. This paper aims to provide a simple and effective method for the fault diagnosis of rolling bearings under variable conditions. The main contribution of this paper is as follows: (1) The refined composite multiscale fuzzy entropy (RCMFE) is applied in bearing fault feature extraction because of its simplicity and high efficiency; (2) The improved support vector machine (ISVM), based on the whale optimization algorithm (WOA), is proposed to identify the fault pattern of rolling bearings. The ISVM is proposed in this paper to solve the problem that parameter setting affects the classification effect of SVM. In the ISVM, the WOA is employed to optimize both the regularization and kernel parameters of the SVM. Compared with the traditional optimization methods, the WOA has the advantages of high optimization speed and better optimization ability; (3) Combining the RCMFE and the ISVM to diagnose bearing fault under variable working conditions. The effectiveness of the RCMFE-ISVM has been validated via experimental vibration signal of bearings faults under variable working conditions.
Quality-Factor Enhancing Locations for Substrate Mounted Resonators
Authors: Anilkumar Allen , George Arun , Sharma N. Gireesh
Published: October 2020

An important but often overlooked factor that affects the performance of a meso/micro electro mechanical vibratory sensor is the structural interaction between the sensor's resonator and the substrate on which it is mounted. Situating resonators at node points eliminates this interaction and thereby helps to improve a resonator's quality-factor for a particular mode of vibration. This paper addresses the problem of locating a single degree of freedom spring-mass resonator on a generic cantilever substrate. The loci of natural frequencies obtained when the resonator's mounting location is varied are developed, and the nodal locations are identified. Thereafter a method to obtain these locations from the characteristic equation without solving the associated eigenvalue problem is described. Lookup tables detailing the nodal locations and the corresponding natural frequencies for various resonator parameters are presented. It is found that at these special nodal locations, the magnitude of the power transmitted through anchors is negligible, which ensures minimal structural interaction between the resonator and the substrate.
Tuned Gyro-Pendulum Stabilizer for Control of Vibrations in Structures
Authors: Unker Faruk
Published: October 2020

A special combined gyro-pendulum stabilizer (a gyroscope with coupling to a pendulum) mounted on a vibrating mass is considered for investigation of the vibration responses. This paper mainly focuses on the derivation of the frequency equations and on finding the required angular momentum for vibration control of the system. Besides, there is also an ANSYS simulation model of gyro-pendulum, which was built to verify the mathematical model. The dynamic responses of both that obtained from ANSYS simulation and that obtained from numerical solving of a Lagrangian mathematical model are analyzed comparatively. The angular momentum ($Omega I_p$), in relation to the natural frequency ($omega_n$) of the primary mass, shows that this vibration control device is more adaptable than other conventional ones by producing unidirectional thrust along the forcing excitation axis whilst the gyroscope is spinning.
Utilization Copula in Determination of Shallot Insurance Premium Based on Regional Harvest Results
Authors: Rusyda Hasna Afifah , Soleh Achmad Zabar , Noviyanti Lienda , Chadidjah Anna , Indrayatna Fajar
Published: October 2020

Abstract: Shallot is one of the highest-yielding horticultural crops in Indonesia and has the tendency to increase the profits of farmers in Indonesia. But until now in Indonesia there is no insurance for horticultural crops other than corn, whereas the shallot farmers face various sources of risk such as weather changes, pest attacks, or other technical factors that ultimately lead to uncertainty of agricultural yields (revenue risk). To overcome this loss, insurance companies can make products based on shallot yields and shallot market prices. Therefore it is essential to grasp the distribution of risk variables (shallot yields and shallot market prices) that interact simultaneously, not separate from one another. Omitting dependencies among risk variables can cause biased risk estimation. Copula can model the non-linear dependencies and can identify the structure of the dependencies between variables. The suitable copula for modeling yield and price risk of shallot is simulated to compute the premium. Result show that clayton copula is suitable for dependence modelling between risk variables.

Authors: Suryanto Edi , Erwanto Yuny , Astuti Sylvie
Published: October 2020

Contamination that decreased chicken meat quality could be prevented using natural preservatives. Bay leaves (Syzygium polyanthum) contain volatile fatty acids, tannin, and flavonoid that possess bacteriological and fungicidal activity as well as preventing bacterial spore growth. The purpose of this study was to determine the effect of fresh bay leaf infusion on microbiological, chemical, and physical qualities of chicken meat. This study used bay leaves, water, chicken meat, eight strain of bacteria, chemicals and materials for the analysis of chicken meat. The experiment consisted of two steps, the first was the antibacterial properties of bay leaves and the second was the application of bay leaf infusion for chicken meat. Eight bacteria was used for the bacterial inhibition of bay leaf at the concentration of 0, 5, 10, 15 and 20%. The experiment on antibacterial properties of bay leaf (Syzygium polyanthum) used one way randomized design with five concentration treatments, while the application of bay leaf infusions on chicken meat using factorial completely randomized design 2x5 (2 types of soaking and 5 observation time). At the second step, chicken meat was divided into 2 groups, the first group was soaked in water only and the second group was soaked in 15% bay leaf infusion. They were then stored for 0 (control), 2, 4, 6, and 8 hours at the room temperature. Each treatment was repeated four times. The microbiological, chemical, physical qualities of chicken meat were observed. The results showed that bay leaf infusion had the ability to inhibit the growth of bacteria (P<0.05). The highest growth inhibition was found on Leuconostoc mesenteroides, whereas the lowest growth inhibition was on Pseudomonas putida. Bay leaf infusion influenced the number of bacteria in chicken meat. The concentration of 15% bay leaf infusion could decrease bacterial number amounting to 1 log CFU/mL compared to control. The number of bacteria of chicken meat stored significantly increased during the storage (P<0.05). However, the number of bacteria of chicken meat soaked in bay leaf infusion was significantly lower than the control. Bay leaf infusion has no significant effect on the chemical quality of chicken meat but it did on the physical quality of chicken meat. The conclusion of the study was bay leaf infusion could inhibit the bacterial growth and reduced the amount of bacteria in chicken meat, whereas storage time influenced the microbiological and physical qualities of chicken meat.

The purpose of present study was to evaluate the performance of broilers fed the commercial diet partially substituted with leubim fish (Canthidermis maculata) waste meal (LFWM) treated by fermentation and without fermentation. As many as 100 broiler chicks, MB 202 strain, unsex, were reared up to 5 weeks in this study. The research was set up into randomized block design (RBD) consisting of 5 treatments and 4 blocks with 5 birds each. Blocks were as replicate based on the body weights of the birds at the beginning of feeding experimental diets. The experimental diets were commercial diets partially replaced with LFWM administered by either fermentation or not with the level of 6 and 12% each, 6.5% and 13% yellow corn, and 0.5% topmix. The data was analyzed using an Analysis of Variance (AOV) and continued by Duncan’s Multiple Range Test (DMRT) only if significant effects were detected among the treatments. The result of recent study indicated that the inclusion of feeds containing LFWM treated by either or not fermented combined with yellow corn and topmix as partially substitution of commercial diets significantly increased (P<0.05) FBW, BWG, feed intake, and protein intake compared to those fed full commercial diet. However, FCR and PER were not significantly affected. DMRT indicated there were no significant diferences in broiler performances fed the feeds containing LFWM treated by fermentation vs without fermentation.

Published: October 2020

This study was done to determine the effects of bale sizes of bio-ammoniated rice straw on its nutrient quality and in vitro digestibility. Rice straw were bio-ammoniated by adding 2 g urea and 1 g probiotic/kg DM. By following a completely randomized design, rice straw was baled in 3 different weights (15, 25, and 35 kg) with six replications for each treatment, and then stored for 3 weeks. In the end of the week 3, bales were opened, aired, and then sampled for proximate analysis (dry matter, organic matter, crude protein, and crude fiber) and digestibility by in vitro gas production method. Using analysis of variance method, the proximate data showed that greater the bales size (15, 25, and 35 kg) increased crude protein (7.59, 7.86, and 9.95%, respectively; P<0.05) and decreased crude fiber contents (24.1, 22.1, and 18.8%, respectively; P<0.05). By increasing the size of bales also increased a, b, and c fractions (-0.79, 0.26, and 0.82 mL/100 mg DM; 20.2, 18.2, and 17.6 mL/100 mg DM; 0.012, 0.014, and 0.019 mL/h, respectively; P<0.05) as well as gas production (11.4, 11.5, and 13.8 mL/100 mg DM, respectively; P<0.05). It can be concluded that packing bio-ammoniated rice straw in 35 kg bale is the most effective way in increasing nutrient quality and digestibility of rice straw.

The Pennsylvanian Composite Volcanism in the Bogda Mountains, NW China: Evidence for Postcollisional Rift Basins
Authors: Wang Jialin , Wu Chaodong , Li Zhuang , Zhou Tianqi , Zhou Yanxi , Feng Geng , Jiao Yue
Published: October 2020

In this paper, we present new petrological, zircon U–Pb–Hf isotopic, bulk-rock geochemical, and Sr–Nd isotopic data for the rocks from the Pennsylvanian Liushugou and Qijiagou Formations, Bogda Mountains (BMs), northwest China. The new data help in understanding the petrogenesis and geodynamic background of the two formations, further constraining the evolution of BMs during the Pennsylvanian. The eastern Liushugou Formation is composed mainly of bimodal volcanic rocks, while the western Liushugou Formation is dominated by pillow basalts with interstitial limestones, peperites, and pyroclastic rocks. The Qijiagou Formation consists principally of bioclastic limestones, peperites, and volcanic and volcaniclastic rocks with turbidites. Depositional environment analyses of the Liushugou and Qijiagou Formations reveal subaqueous volcanism and a progressively deepening shallow marine environment with times. Zircon LA-ICP-MS U–Pb dating of felsic volcanic rocks from the Liushugou Formation indicates that the subaqueous volcanism occurred at ca. 310–302 Ma, viz., the Pennsylvanian era. The basaltic rocks from the Liushugou and Qijiagou Formations are high-K calc-alkaline, enriched in light rare earth elements and large-ion lithophile elements, and depleted in high-field-strength elements (Nb, Ta, and Ti). The above characteristics, together with their depleted isotopic signature (εNdt=3.0-8.1, εHft=8.0-15.6, and ISr=0.703-0.707), suggest the derivation from a depleted mantle source metasomatized by slab-derived fluids and sediment-derived melts. Most felsic volcanic rocks of the high-K calc-alkaline to shoshonite series from the Liushugou and Qijiagou Formations show features of the A2-type granites and have similar trace and isotopic composition to the basaltic rocks, which were probably generated from the partial melting of juvenile continental crust. Combining the newly acquired data with the regional geology, we propose that the Pennsylvanian volcanic and sedimentary rocks in the BMs were formed in a series of postcollisional rift basins which were related to local strike-slip faulting. Moreover, the volcanic rocks in the east were derived from a relatively deeper mantle source (thick lithosphere) due to their smaller rifting.
Primary Healthcare Seeking Behaviour of Low-income, Uninsured Patients Across the Public and Private Health Sectors in South Africa
Authors: Govender Kerensa , Girdwood Sarah , Letswalo Daniel , Long Lawrence , Meyer-Rath G , Miot J
Published: October 2020

Background: The proposed National Health Insurance (NHI) system aims to re-engineer primary healthcare (PHC) in South Africa, envisioning both private sector providers and public sector clinics as independent contracting units to the NHI Fund. In 2017, 16% of the South African population had private medical insurance and predominately utilised private providers. However, it is estimated that up to 28% of the population access private PHC services, with a meaningful segment of the low-income, uninsured population paying for these services out-of-pocket. The study objective was to characterise the health seeking behaviour of low-income, uninsured patients accessing PHC services in both the public and private sectors, patient movement between sectors, and factors influencing their facility choice. Methods: We conducted once-off patient interviews on a random sample of 153 patients at 7 private PHC providers (primarily providing services to the low-income uninsured patient population) and their matched public PHC clinic (7 facilities). Results: The majority of participants were economically active (96/153, 63%), 139/153 (91%) did not have health insurance, and 104/153 (68%) earned up to $621/month. A multiple response question found affordability (67%) and convenience (60%) were ranked as the most important reasons for choosing to usually access care at public clinics (48%); whilst convenience (71%) and quality of care (59%) were key reasons for choosing the private sector (32%). There is movement between sectors: 23/76 (30%) of those interviewed at a private facility and 8/77 (10%) of those interviewed at a public facility indicated usually accessing PHC services at a mix of private and public facilities. Results indicate cycling between the private and public sectors with different factors influencing facility choice. Conclusions: It is imperative to understand the potential impact on where PHC services are accessed once affordability is mitigated through the NHI as this has implications on planning and contracting of services under the NHI.
Health System Costs of Rheumatic Heart Disease Care in South Africa
Authors: Hellebo Assegid G. , Zuhlke Liesl J. , Watkins David A. , Alaba Olufunke A.
Published: October 2020

BackgroundRheumatic Heart Disease (RHD) is a disease of poverty that is neglected in developing countries, including South Africa. Lack of adequate evidence regarding the cost of RHD care has hindered national and international actions to prevent RHD related deaths. The objective of this study was to estimate the cost of RHD-related health services in a tertiary hospital in the Western Cape, South Africa. MethodsThe primary data on service utilization were collected from a randomly selected sample of 100 patient medical records from the Global Rheumatic Heart Disease Registry (the REMEDY study), a registry of individuals living with RHD. Patient-level clinical data, including, prices and quantities of medications and laboratory tests, were collected from the main tertiary hospital providing RHD care. All annual costs from health system perspective were estimated in 2017 (base year) South African Rand (ZAR) using a combination of ingredients and step-down costing approaches and later converted to United States dollars (US$). Step-down costing was used to estimate provider time costs and all other facility costs such as overheads. 3% discount rate was also employed in order to allow depreciation and opportunity cost. We aggregated data to estimate the total annual costs and the average annual per-patient cost of RHD and conducted a one-way sensitivity analysis. ResultsThe estimated total cost of RHD care at the tertiary hospital was US$ 2 million (in 2017 US$) for the year 2017, with surgery costs accounting for 65%. Per-patient average annual costs were US$ 3900. For the subset of costs estimated using the ingredients approach, outpatient medications, and consumables related to cardiac catheterization and heart valve surgery were the main cost drivers. ConclusionsRHD-related healthcare consumes significant tertiary hospital resources in South Africa, with annual per-patient costs higher than many other non-communicable and infectious diseases. This analysis supports the scaling up of primary and secondary prevention programs at primary health centers in order to reduce future tertiary care costs. The study could also inform resource allocation efforts and provide cost estimates for future studies of intervention cost-effectiveness.

Background The ongoing COVID-19 pandemic and subsequent lockdown have adversely affected global health care services to varying extent. Emergency Services were also affected along with elective surgeries, which were deferred to accommodate the added burden of COVID 19 affected patients, on the healthcare systems. We aimed to assess the change in delivery of essential and emergency surgeries due to the pandemic.Methodology A research consortium led by WHO Collaboration Centre (WHOCC) for Research in Surgical Care Delivery in Low- and Middle-Income countries (LMIC), India, conducted this retrospective cross-sectional study with 12 recruited centers. All surgeries performed during the months of April 2020 were compared with those performed in April 2019. These surgeries were stratified into emergency and elective, and further categorized based on NHS surgery prioritization documents. Results A total of 4396 surgeries were performed at these centers in April 2019 and 1216 surgeries were performed in same month during 2020, yielding a fall of 72.3% (1216 /4396).We found a 54% reduction in emergency surgeries and a 91% reduction in the elective surgeries. Number of cesarean sections reduced by 29.7% and fracture surgeries declined by 85.3% Laparotomies and surgeries for local soft tissue infections with necrotic tissue reduced by 71.7% and 69.5% respectively.Conclusion Our study quantifies the effects of COVID 19 pandemic on surgical care delivery in India and documents that the overall surgical volume reduced by three fourths in the pandemic period. Emergency surgeries reduced to half when compared with pre-pandemic period. Cesarean section surgeries were affected the least by pandemic, whereas the fracture surgeries and laparotomies were affected the most.

Introduction Syria has suffered for nine years of war and there were huge demands for blood during and after the lockdown from Coronavirus disease of 2019 (COVID-19).Methods Online questionnaires were distributed to Social Media groups after two weeks of the 10-week full lockdown to determine blood donation patterns. They also included stress, anger, and COVID-19 distress questions.Results The study included 1423 participants, 899 (63.2%) of which were females. Around 48.5% have donated blood, of which 33.3% donated only once in their lifetime. Not having a good reason to donate blood was the main declared reason for not donating, and obtaining a document was the main reason for donating in (64.8%) of participants who had donated blood. Stress, anger, and being distressed to get infected did not have a crucial effect on blood donation, and its patterns. Losing someone close and being endangered from war were associated with more frequent blood donation in contrast to being distressed from war which was more associated with distress from getting infected.Conclusion Distress from COVID-19 was not the main reason for not donating blood. Spreading the culture of volunteer blood donating is crucial as COVID-19 exposure with blood donation can be avoided.

BackgroundA large number of preclinical studies have shown that local anesthetics have a direct inhibitory effect on biological activities, including cell survival, proliferation, migration, and invasion. There are few studies on the role of local anesthetics in cancer stem cells. This study aimed to determine the possible role of local anesthetics in glioblastoma stem cell (GSC) self-renewal and the underlying molecular mechanisms.MethodsThe effects of local anesthetics in GSCs were investigated through in vitro and in vivo assays (i.e., cell counting kit 8, spheroidal formation assay, double immunofluorescence, western blot, and xenograft model). The Acyl biotin exchange method (ABE) assay was identified proteins that are S-acylated by zinc finger Asp-His-His-Cys-type palmitoyltransferase 15 (ZDHHC15). Western blot, co-immunoprecipitation, and liquid chromatograph mass spectrometer-mass spectrometry assays were used to explore the mechanisms of ZDHHC15 in effects of local anesthetics in GSCs.ResultsIn this study, we identified a novel mechanism through which local anesthetics can damage the malignant phenotype of glioma. We found that local anesthetics prilocaine, lidocaine, procaine, and ropivacaine can impair the survival and self-renewal of GSCs, especially the classic glioblastoma subtype. These findings suggest that local anesthetics may weaken ZDHHC15 transcripts and decrease GP130 palmitoylation levels and membrane localization, thus inhibiting the activation of IL-6/STAT3 signaling. ConclusionsIn conclusion, our work emphasizes that ZDHHC15 is a candidate therapeutic target, and local anesthetics are potential therapeutic options for glioblastoma.

BackgroundApart from the most prominent symptoms in Autism spectrum disorder (ASD), namely deficits in social interaction and repetitive behavior, patients often show abnormal sensory reactivity to environmental stimuli. Especially potentially painful stimuli are reported to be experienced in a different way compared to healthy persons.MethodsIn our present study, we present an ASD patient carrying compound heterozygous mutations in the voltage-gated sodium channel (VGSC) Nav1.8, which is preferentially expressed in sensory neurons. We expressed both identified mutations, p.I1511M and p.R512X, in a heterologous expression system and investigated their biophysical properties using patch-clamp recordings. ResultsThe results of these experiments suggest that both mutations lead to different degrees of loss-of-function of Nav1.8. Behavioral experiments in a Nav1.8 loss-of-function mouse model additionally revealed Nav1.8 may play a role in autistic behavior. LimitationsOur study did not verified the functions of p.I1511M and p.R512X mutations in vivo. The mice with these mutations can be constructed to verify the mutation functions in the future investigations. In addition, since we have only found one ASD patient which may relate to SCN10A mutations, the role of Nav1.8 in ASD needs to be confirmed in more cases. Moreover, the cellular mechanism underlying the effect of Nav1.8 on ASD needed to be explored in future studies.ConclusionsOur results present Nav1.8 as a protein potentially involved in ASD pathophysiology and may therefore offer new insights to the genetic basis of this disease.

Objectives Head lice infection can lead to inferiority, depression, insomnia, and lack of education, loss of social status, secondary infections, hair removal, and allergies. Body lice can carry dangerous diseases such as typhus, trench fever, and recurrent fever. Studies on lice control due to pesticides, inappropriate drug use, pesticide risks, and pesticide resistance in the lice population are needed. The study of insect symbiotic microorganisms such as Wolbachia is a new approach to control the vector-borne disease. ResultsThe presence of this bacterium was investigated in head and body lice collected from the Iranian lice population. Genomic DNA was extracted from both lice specimens and PCR assay was performed to the detection of Wolbachia infection by using Wsp, coxA, and gatB primers. All PCR results were negative for Wolbachia in comparison with positive controls. Further studies should be performed using new molecular markers to determine the Wolbachia infection of lice.

Background: The purpose of this study is to find how trunk muscles mainly used in cardio-pulmonary resuscitation, including pectoralis major, rectus abdominis, and erector spinae, influence the result of 8-minute when the muscles have six-weeks plank exercise, and to analyze the duration time of exercise effect. Methods: Study subjects were 30 participants taking a relevant course for 24 months. After they had plank exercise for six weeks, they didn't have any exercises including plank exercise for six weeks. As such, the students participated in the 12-weeks program. For chest compression simulation, a practictical mannequin was used. Without any respiration, a single rescuer continued to perform only chest compression for 8 minutes. Results: Regarding their change in a muscle mass by plank exercise, there was a statistically significant difference in the change from 4th to 8th week after the program (p<.01). The muscle activity change had a statistically significant difference from 3rd to 10th week (p<.01). The chest compression depth had a statistically significant difference from 4th to 8th week (p<.01). The chest compression rate didn't had a statistically significant difference for 12 weeks. In addition, insufficient chest relaxation height after compression had a statistically significant difference from 4th to 10th week(p<.01). The chest compression maintenance time had a statistically significant difference from 2nd to 12th week (p<.01). Conclusion: If the study subjects have three sets of plank exercise program for five weeks, which consisted of one set of 10 times of 30-second motion and 20-second rest and does not have up to two weeks of detraining, the plank exercise is considered to be helpful for them in out of hospital cardiac arrest at the time when there is no use of mechanical chest compression device.Trial registration: The study was registered on 12/15/2015 in the Chungnam National University Hospital with number 2015-10-035-005.
