The torsion beam type of rear suspension has been adopted by most manufactures of small to medium front wheel drive passenger cars. Previous studies analyzed only the load characteristics of CTBA(the coupled torsion beam axle)'s components. This paper analyzed the results of measurement after measuring loads and displacements, angles when a car equipped with the coupled torsion beam axle is driving in various roads. The most important durability factors for CTBA part are the force and direction of rear CTBA trailing arm. If there are design changes, it was difficult to make a sensor and install each time for measuring the trailing arm forces. After analyzing the loading histories between body and chassis, we developed the transformation matrix that can be converted to mutual force. This paper also deals with the analysis of the force behavior through the analysis of the influence and correlation between the body and chassis parts of cars.

Studies were made to remove the toxic phytohormone, 2,4-D, in suspension cultures of Panax vietnamensis. Cells grown in normal MS medium with 2,4-D were inoculated and grown in the MS medium without hormone. Not a big difference was observed in growth characteristics between media with and without 2,4-D. The 2,4-D in the culture, however, was completely removed. During the culture, the residual 2,4-D was consumed rapidly at the early growth stage. The intra-cellular 2,4-D was consumed first and the 2,4-D in the medium was used afterward.

Recently, the Internet Corporation for Assigned Names and Numbers (ICANN) announced the expansion of the number of generic top-level domains (gTLDs) beyond the current 22 gTLDs, and the gTLD Applicant Guidebook for ICANN's new gTLD program is now under consideration for approval. ICANN also introduces a "Trademark Clearinghouse" and the "Uniform Rapid Suspension (URS)" procedure to protect trademarks and expedite dispute resolution and save costs. The Trademark Clearinghouse is a central repository for information to be authenticated, stored and disseminated, pertaining to the rights of the trademark holders. Trademark holders would voluntarily provide data of their trademarks from all over the world, and it would assist a trademark watch service provided by the new gTLD registry for trademark holders and potential domain name registrants. The URS is a part of the new gTLD dispute resolution mechanisms created by ICANN to resolve cybersquatting disputes. A complainant in a URS proceeding must establish three elements that are very similar to the existing UDRP to succeed, but supposedly more expedited and cost efficient. Since the URS provides that it only protects court validated and registered trademarks, it is not clear whether unregistered marks used in commerce are protected under the URS. The URS escalates the complainant's burden of proof from a preponderance of evidence standard under the UDRP to a clear and convincing evidence standard. The notices to a respondent shall be sufficient if the URS Provider sends the notice of Complaint to the addresses listed in the Whois contact information. As registrants who wish to conceal their true identity often subscribe to the privacy/proxy service and the complainant's high rate of success in the UDRP proceeding is relevant to the respondents' default rate, the URS's simple notice requirement would deprive respondents of a fair opportunity to assert their rights over the disputed domain names.

This study was conducted to examine the resources that influence the choice of drop-out students' reentry to school. A total of five years of panel analysis of 2,553 drop-out teenagers from 2013 to 2017 were utilized. In order to verify the resources that affect the choice of school reentry of teenagers with experiences of suspension of studies to formal middle and high school after July 2012, this study analyzed drop-out teenagers' family resources as well as their psychological, mental, and social-relationship resources. A crossover analysis, t-test, and hierarchical logistic regression analysis were conducted. The major outcomes of this study are as follows: First, the socio-demographic variables among the resources that affected the choice of reentry for school of teenager children were the type of family and number of moves to a new house. Second, the psychological and sentimental variable that affected the choice of school reentry was a decreasing level of positive recognition of the situation of suspension of studies combined with depression, impulsiveness, and perceiving society as one that discriminates based on the level of education. Third, significant family resource variables were the type of family form and parents providing economic support, which is a subfactor of parental attachment. Fourth, the presence of a mentor as a helpful social-relationship resource had a significant effect on relational resources. This study is significant in the sense that the positive family resources that affect the choice of school reentry of drop-out teenage students were determined, and the positive directivity of supportive family resources is presented for parents with teenage children experiencing a suspension of studies.

The presence of traffic on a slender long-span bridge deck will modify the cross-section profile of the bridge, which may influence the flutter derivatives and in turn, the critical flutter wind velocity of the bridge. Studies on the influence of vehicles on the flutter derivatives and the critical flutter wind velocity of bridges are rather rare as compared to the investigations on the coupled buffeting vibration of the wind-vehicle-bridge system. A typical streamlined cross-section for long-span bridges is adopted for both experimental and analytical studies. The scaled bridge section model with vehicle models distributed on the bridge deck considering different traffic flow scenarios has been tested in the wind tunnel. The flutter derivatives of the modified bridge cross section have been identified using forced vibration method and the results suggest that the influence of vehicles on the flutter derivatives of the typical streamlined cross-section cannot be ignored. Based on the identified flutter derivatives, the influence of vehicles on the flutter stability of the bridge is investigated. The results show that the effect of vehicles on the flutter wind velocity is obvious.

Objectives: This study was performed to examine the antigenic potential of pure melittin (Sweet Bee Venom - SBV) extracted from the bee venom by utilizing protein isolation method of gel filtration. Methods: All experiments were conducted at Biotoxtech (Chungwon, Korea), authorized a non-clinical studies institution, under the regulations of Good Laboratory Practice (GLP). Antigenic potential of SBV was examined by active systemic anaphylaxis (ASA) and passive cutaneous anaphylaxis (PCA) in guinea pigs. SBV was subcutaneously administered at 0.07 and 0.28mg/kg and also as a suspension with adjuvant (Freund's complete adjuvant: FCA). Ovalbumin (OVA) as a suspension with adjuvant was used to induce positive control response ($5mg/m{\ell}$-FCA). Results: 1. In the ASA test, experimental groups showed some symptoms of anaphylaxis like piloerection, hyperpnea and staggering gait. 2. In the PCA test, low dosage group did not show any antibody responses, whereas high dosage group showed positive responses. 3. In the weight measurement and clinical observation, experimental groups didn't show any significant changes compared with control group. 4. In the autopsy of body, the abnormalities of lung were detected in the corpse. This means that the cause of death may induced anaphylactic shock. Conclusions: Above findings suggested that SBV had antigenic potential in guinea pig. Further studies on the subject should be conducted to yield more concrete evidences.

The non-linear behaviour of electrorheological (ER) and magnetorheological (MR) dampers makes it difficult to design effective control strategies, and as a consequence a wide range of control systems have been proposed in the literature. These previous studies have not always compared the performance to equivalent passive systems, alternative control designs, or idealised active systems. As a result it is often impossible to compare the performance of different smart damper control strategies. This article provides some insight into the relative performance of two MR damper control strategies: on/off control and feedback linearisation. The performance of both strategies is benchmarked against ideal passive, semi-active and fully active damping. The study relies upon a previously developed model of an MR damper, which in this work is validated experimentally under closed-loop conditions with a broadband mechanical excitation. Two vibration isolation case studies are investigated: a single-degree-of-freedom mass-isolator, and a two-degree-of-freedom system that represents a vehicle suspension system. In both cases, a variety of broadband mechanical excitations are used and the results analysed in the frequency domain. It is shown that although on/off control is more straightforward to implement, its performance is worse than the feedback linearisation strategy, and can be extremely sensitive to the excitation conditions.

In this study, we examined the characteristics of alkali gelatinization of corn starch. Here, the degree of corn starch gelatinization increased exponentially with the NaOH concentration of the starch slurry. The alkali gelatinization initiation point (AGIP) was obtained from the intersection point of gelatinization slope line, which resulted from the regression of the logarithmic degree of gelatinization, and was markedly changed. The effects of temperature and corn starch concentration on alkali gelatinization were studied with a 10%(w/w) corn starch suspension. We found that this corn starch suspension gelatinized in 24.1 meq/g starch of NaOH at $40^{\circ}C$, and in 9.8 meq NaOH/g starch at $60^{\circ}C$. Moreover, a 40%(w/w) corn starch suspension gelatinized with 9.5 meq NaOH/g starch, even at $40^{\circ}C$. These results indicate that the amount of alkali added for the gelatinization of corn starch has an inverse relationship with the temperature and concentration of corn starch.

During normal operating conditions, a motor vehicle is constantly subjected to a variety of forces, which can adversely affect its straight-ahead motion performance. These forces can originate both from external sources such as wind and road and from on-board sources such as tires, suspension, and chassis configuration. One of the effects of these disturbances is the phenomenon of vehicle lateral-drift during straight-ahead motion. This paper examines the effects of road crown, tires, and suspension on vehicle straight-ahead motion. The results of experimental studies into the effects of these on-board and external disturbances are extremely sensitive to small changes in test conditions and are therefore difficult to guarantee repeatability. This study was therefore conducted by means of computer simulation using a full vehicle model. The purpose of this paper is to gain further understanding of the straight-ahead maneuver from simulation results, some aspects of which may not be obtainable from experimental study. This paper also aims to clarify some of the disputable arguments on the theories of vehicle straight-ahead motion found in the literature. Tire residual aligning torque, road crown angle, scrub radius and caster angle in suspension geometry, were selected as the study variables. The effects of these variables on straight-ahead motion were evaluated from the straight-ahead motion simulation results during a 100m run in free control mode. Examination of vehicle behavior during straight-ahead motion under a fixed control mode was also carried out in order to evaluate the validity of several disputable arguments on vehicle pull theory, found in the literature. Finally, qualitative comparisons between the simulation results and the test results were made to support the validity of the simulation results.

Anchors and saddles are used to have sufficient geometrical rigidity and make target configuration of main cable of suspension bridge. Neglecting the sliding effect at saddles, points at them have been idealized as fixed nodes in lots of former studies. In general, sliding effects are reported to show significant structural behaviors of main cable and cause to the different responses of bridges. During early erection steps of the suspension bridge, especially, the sliding effect occurs easily because there is large difference of cable tension between main and side span in removing set-back ropes or not applying set-back. This study presents the finite element analysis considering to cable sliding effect and shows the comparison of differences between sliding and non-sliding at election sequence. The analysis of sliding between main cables and saddles needs to obtain more realistic responses because the analysis result can represent unfavorably different responses of bridges. Moreover, the sliding analysis method and results in this study can be used to basic criteria in engineering design and construction steps.
