Abstract:

Abstract. Base on previous studies showing that sugar palm fruit can be made as jam with the addition of Asian melastome fruit as a natural coloring. This sugar palm fruit jam product is packaged with jar and pouch packaging. shelf Life information for this product is unknown. The purpose of this study is to determine the rate of change in quality, critical parameters, and estimate the shelf life of sugar palm fruit jam with Arrhenius Model which is simulated at three storage temperature conditions (28⁰C, 38⁰C, and 48⁰C). Parameters observed during the storage process are water content, water activity (aw), pH, color (L), anthocyanin, and antioxidant activity (IC50). The results showed that the smallest activation energy value was used to determine product shelf life, it is color parameters (L) (first order reaction) with linear regression y = -4715.x + 9,787 on jar bottle packaging and y = -2021.x + 1,387 on packaging pouch. The age of storing sugar palm fruit jam with jar bottles is 93 days at 28⁰C and on the packaging pouch for 40 days at 28⁰C.

Abstract:

According to the characteristic of mixing and flocculation of water plant, the calculation formula of the simulation rotational speed of agitator was proposed for the coagulation-flocculation jar test of optimum dosage, which was based on the basic principle that the velocity gradient of production is equal to that of experiment. Obtained the calculation formula for related parameters about coagulation agitator through the determination of the actual production velocity gradient and combined with the coagulation jar test data in laboratory, such as the power consumption of the paddle boards; the proportional coefficient of coagulation agitator and the agitation speed etc. The result shows that the experiment simulation according with the effect of practical produce of water plant can provide the reliable optimum dosage of coagulant for the practical production. This research has a great signality to waste-water treatment, Results not only have great economic benefit, but also can achieve a certain ecological benefit, accorded with the demand of developing low carbon environmental protection.

Abstract:

In recent climatic events in Australia, the need for frequent jar testing to determine optimum coagulant and flocculant aid doses became apparent in order to determine optimum treatment efficiencies. The generally applied jar test procedure can be time consuming and this prompted investigations for capacity to test waters more rapidly, for a range of treatment conditions and raw water qualities. The aim of the study reported here was to develop a rapid procedure for determination of dissolved organic matter (DOM) removal, measured as dissolved organic carbon (DOC) and UV absorbance (254 nm/cm) for a range of treatment conditions (coagulant dose and pH). Using a previously established predictive model (mEnCo) for coagulant determination, several coagulant doses were then predicted for application in a modified jar test protocol. Best fitted and predicted data using the exponential decay function compared with data from a 6× jar test procedure were obtained using three doses, 0.5× EnCD, EnCD and a VHD (≥2× EnCD). It is proposed that this procedure may be used to more rapidly determine treatment efficiency based on the removal of organics compared with traditionally applied jar tests.

Abstract:

Abstract. Currently, the proper utilization of water treatment plants and optimizing their use is of particular importance. Coagulation and flocculation in water treatment are the common ways through which the use of coagulants leads to instability of particles and the formation of larger and heavier particles, resulting in improvement of sedimentation and filtration processes. Determination of the optimum dose of such a coagulant is of particular significance. A high dose, in addition to adding costs, can cause the sediment to remain in the filtrate, a dangerous condition according to the standards, while a sub-adequate dose of coagulants can result in the reducing the required quality and acceptable performance of the coagulation process. Although jar tests are used for testing coagulants, such experiments face many constraints with respect to evaluating the results produced by sudden changes in input water because of their significant costs, long time requirements, and complex relationships among the many factors (turbidity, temperature, pH, alkalinity, etc.) that can influence the efficiency of coagulant and test results. Modeling can be used to overcome these limitations; in this research study, an artificial neural network (ANN) multi-layer perceptron (MLP) with one hidden layer has been used for modeling the jar test to determine the dosage level of used coagulant in water treatment processes. The data contained in this research have been obtained from the drinking water treatment plant located in Ardabil province in Iran. To evaluate the performance of the model, the mean squared error (MSE) and correlation coefficient (R2) parameters have been used. The obtained values are within an acceptable range that demonstrates the high accuracy of the models with respect to the estimation of water-quality characteristics and the optimal dosages of coagulants; so using these models will allow operators to not only reduce costs and time taken to perform experimental jar tests but also to predict a proper dosage for coagulant amounts and to project the quality of the output water under real conditions.

Abstract:

An expert system has been developed to aid the operators of small water treatment plants. A tutorial component of the expert system explains the possible reasons for common problems by focusing on the jar test analysis for chemical dosage control. The tutor provides an operator with the opportunity to run the jar test, receive feedback on the parameters selected, visualize the results on the actual water treatment processes, and be tutored in the topics related to understanding the processes involved and additional supplemental areas such as concentrations and conversions. A background of Intelligent Tutoring Systems, along with a justification of the approach, is provided. The development of the jar test tutor including knowledge representation is described.

Abstract:

Objectives: To compare the performance of panoramic radiography (PAN) and cone beam CT (CBCT) in the detection of juxta-apical radiolucency (JAR), as well as to investigate, in CBCT images, if there are factors associated with the detection of JAR on PAN. Methods: Two oral radiologists assessed the presence of JAR in PAN and CBCT images of 175 individuals (308 mandibular third molars). The cortical plates involvement and the JAR size and location were assessed on CBCT to evaluate if these factors were related to JAR detection on PAN. McNemar’s test and multiple logistic regression were performed. Results: PAN and CBCT differed significantly in the detection of JAR (p = 0.001). On PAN, JAR was identified on 24% of the patients while on CBCT its detection increased to 32.6%. JAR was detected only on CBCT and only on PAN in 26 and 7 cases, respectively. Distal/mesial surfaces of dental roots were where JAR was mostly located (84.5%), cortical thinning was found in 59.2% of cases and the mean (SD) of JAR size was 5.03 (±1.8) mm. However, these factors were not associated with JAR detection on PAN (p > 0.05). On the other hand, the location of the cortical involvement (if buccal or lingual) was associated with JAR detection on PAN, which was more detectable when the thinning was on buccal cortical. Conclusions: Juxta-apical radiolucency is more often detected on CBCT than on PAN. JAR detection on PAN was improved when it was related to the buccal cortical plate of the mandible.

Abstract:

This study aimed to compare a variant of the check-all-that-apply (CATA) method, CATA with just-about-right (JAR) scales (CATA-JAR), with the CATA and rate-all-that-apply (RATA) methods for evaluating 12 Korean traditional rice wines (yakju). All consumers (n = 312) assessed each sample on a 9-point hedonic scale and were asked to fill out the CATA, RATA, or CATA-JAR questionnaire using a 5-point JAR scale. The frequency and percentage of terms with significant differences among CATA-JAR samples were significantly higher than those for the CATA method. The regression vector (RV) between the sample and term configurations of the three methods were all over 0.84, indicating that all methods were similar in terms of product and term usage. Regarding the stability of the sample configurations, CATA-JAR could derive a stable value with the lowest number of consumers (n = 25). For the CATA-JAR method, significant penalties for each attribute and product were successfully calculated using the t-test and bootstrapping technique, to identify any attribute detrimental to liking for each product. Overall, considering its better performance in discriminating products and stability, the CATA-JAR method may be used when comparing samples with subtle differences in attributes.

Abstract:

This paper examines the relationships between the turbidity removal efficiency (TRE), the surface overflow rate (SOR), and the detention time (Dt) in settling column and jar tests, as well as the performance of a conventional upflow settling tank modified with inclined plates in the upper zone. The experimental results showed that the SOR obtained from the flocculent settling column test can be increased by 30% and the corresponding Dt can be decreased by 75% with a variation in TRE of less than 7%. The TRE of flocculent settling in the jar test coincided with the performance of the modified upflow settling tank, while the results of the settling column test were slightly different. For plain settling, the SOR obtained from jar and settling column tests should be divided by 3 and 2, respectively, before possible use in the design of the modified upflow settling tank. Two empirical models with 1.0% error in the TRE predictions were developed to facilitate the design of the modified upflow settling tank.

Abstract:

Abstract The objective of this study was to determine the applicability of the laboratory flocculation test (Jar Test) for a solid contact clarifier. Cohesivity, a parameter characterizing the sludge blanket can be established by determining the Sludge Cohesion Coefficient (SCC) by conducting a Sludge Cohesion Test (SCT). A series of laboratory tests were performed using the Jar Test and SCT. Considering the large number of variable parameters involved with natural raw water, sludge samples were prepared using synthetic raw water with varying turbidity and coagulant dose combinations. A comparison was made between the optimum coagulant dose obtained using the two tests. Highest SCC observed at the optimum coagulant dose was within the range of 0.6–3.3 m/hr. Low SCC values indicate a light and fragile sludge blanket whereas high SCC values indicate a quick settling consistent blanket. With increasing raw water turbidity, the optimum coagulant dose given by SCT is lower than that of the Jar Test. Hence, at higher raw water turbidity occurrences, it may be possible to operate the upward flow solid contact clarifiers with lower coagulant dose. A significant quadratic relationship is observed between the optimum coagulation doses with R2 = 0.9 and α < 0.05.

Abstract:

Abstract This paper reports on the development of an automated method to perform sedimentation tests on a suspension, to study the settling and sedimentation behaviour of particle suspension. The standard method for measuring sedimentation rate is the jar test, but this is burdened with some errors: the possibility of misinterpretation of the interface or subjective readings by technicians. In order to overcome these problems, there are many different methods that exclude subjective mistakes. The proposed solution automatically detects the phase separation boundary and, by use of a moving camera, plots the real-time sedimentation curve. The good agreement of settling curves between the manual method, another CCD image processing method and the current technique demonstrates the reliability of the system. This system can be used for testing different types of suspensions. The article presents a comparison of the commonly used method of image analysis and the proposed solution with a tracking camera, based on the example of a coal suspension.

Abstract:

Background: The aim of this pilot study was to assess the safety and dosing of scolopendrid pharmacopuncture (SPP).Methods: A total of 40 healthy Sprague-Dawley rats (males and 20 females 20) were selected following a 7-day inspection and acclimation period. SPP was administered via intramuscular injection, over a 2-week period using 3 doses including a high-dose [0.84 mg of scolopendrid per kg of body weight (BW)], a meddose (0.42 mg/kg BW), and a low-dose (0.21 mg/kg BW). The control group was injected with sterile water into the muscles. Unusual changes caused by administration of the test substance were observed. Weight, feed intake, organ weight, and hematological examinations were compared among the groups. Using the SPSS statistical program, Levene’s test was performed to evaluate the homogeneity of variances, and a one-way ANOVA test was subsequently performed to assess the significance between each test group.Results: During the experiment no animals died. Weight change, food consumption, organ weight, hematological test, and blood biochemical tests showed no significant differences in the treatment groups compared to controls.<br>Conclusion: No toxicological changes related to the administration of test substances were observed. Therefore, the LD<sub>50</sub> (lethal-dose that kills 50%) of scolopendrid pharmacoupuncture in rats was greater than 0.84 mg/kg.

Abstract:

Background: Aconitum sinomontanum Nakai (ASN) has been reported to have analgesic effects. In this study an animal model of pharmacopuncture using ASN (100-500 mg/kg) was examined.Methods: Sprague-Dawley (SD) rats (<i>n</i> = 40) were randomly assigned to ASN-Low (1 mg/mL, 1.8 mL, ASN-L), ASN-Intermediate (5 mg/mL, 1.8 mL, ASN-M), ASN-High (10 mg/mL, 1.8 mL, ASN-H), negative control (0.2 mL normal saline), and positive control (0.2 mL 0.5% lidocaine) groups. All experiments were administered to the rats’ left hind leg. The analgesic response was assessed by monitoring the physical (hot plate, and von Frey test) and chemical (formalin) responses to pain.Results: All ASN pharmacopuncture groups demonstrated significant differences in pain response to the hot plate test, von Frey test, and formalin test, compared to the control group (<i>p</i> < 0.05). The response of the ASN-M group and ASN-H groups to the hot plate, the formalin, and the von Frey tests were significantly different, compared to the lidocaine group (<i>p</i> < 0.05).Conclusion: ASN pharmacopuncture had a significant analgesic effect on SD rats in response to physical and chemical models of pain.

Abstract:

Background: In this retrospective study, we aimed to determine which diagnostic tests were associated with an improvement in Bell’s palsy symptoms. Methods: There were 30 patients who visited Kyung Hee University Korean Medicine Hospital from April 1, 2017 to February 29, 2020, and who received East-West collaboration treatment for Bell’s palsy. The tests included electroneurography (ENoG), electromyography (EMG), hematology, and heart rate variability (HRV) results which were used to determine if any test correlated with improvement of Bell’s palsy symptoms. Results: The initial severity of symptoms did not correlate with the tests performed, with the exception of mean corpuscular hemoglobin concentration (p = 0.013). For both ENoG for oculi degeneration and mean EMG tests, the rate of nerve degeneration showed a significant negative correlation with the improvement of Bell’s palsy symptoms. Amongst the HRV test indicators, the square root of the mean of the sum of the squares of differences between the adjacent normal R-R wave interval, the standard deviation of intervals, total power, very low frequency, and high frequency of the wave was negatively correlated with improvement of Bell’s palsy symptoms. Similarly, glycosylated hemoglobin Type A1c (HbA1c) and erythrocyte sedimentation rate (ESR) showed a negative correlation with improvement of symptoms of Bell’s palsy. With the exception of HbA1c and ESR, the remaining hematology test results showed no significant difference when comparing before and after treatment. Conclusion: ENoG, EMG, HRV test, HbA1c, and ESR negatively correlated with improvements in Bell’s palsy symptoms and may determine the prognosis of Bell’s palsy.
