Publication Metadata only Effectiveness of respiratory resistance training device on respiratory muscles strength and endurance(2013) Sasipa Buranapuntalug; Wattana Jalayondeja; Rungchai Chaunchaiyakul; Mahidol University. Faculty of Physical TherapyRespiratory muscle strength and endurance play critical roles, like a pump, to continuously ventilate air in and out from the lungs. This makes the body possible to prolong physical activity. Respiratory muscle training is, therefore, necessary... to overcome the above limitations, on strength and endurance. Twenty female volunteers (average age = 22.50 ± 2.64) were randomly divided into control (n = 10, no training) and experimental (n = 10, training) groups. The latter group was continuously trainedItem Metadata only Effects of muscle strength between single set and multiple sets on strength training(Mahidol University. Mahidol University Library and Knowledge Center, 2008) Patthanee Settheethanyahan; Sirirat HirunratItem Metadata only Influences of Compressive Strength and Casting Position on Flexural Strength of Polypropylene Fiber-Reinforced Self-Compacting Mortar(2023-07-01) Daungwilailuk T.; Kittikornjarus B.; Kitchanurak S.; Innchou T.; Attachaiyawuth A.; Daungwilailuk T.; Mahidol UniversityThis article presents the results on the effects of compressive strength, amount of polypropylene fiber and casting position on the flexural strength of polypropylene fiber-reinforced self-compacting mortar in order to identify suitable factors... for using such a construction material. The results revealed that the compressive strength slightly improved (around 4%) when the fiber content was 1%. However, compressive strength decreased by 19% when the fiber content increased to 2%.

Department of Advanced General DentistryPURPOSE: To investigate the microtensile bond strength between two all-ceramic systems; lithium disilicate glass ceramic and zirconia core ceramics bonded with their corresponding glass veneers. MATERIALS AND METHODS: Blocks of core ceramics (IPS... microscope (SEM) to identify the mode of failure. One-way ANOVA and the Dunnett's T3 test were performed to determine significant differences of the mean microtensile bond strength at a significance level of 0.05. RESULTS: The mean microtensile bondItem Metadata only Development Mobile App on Android System "Muscle Strength Test"ภวดล รักทวี; มหาวิทยาลัยมหิดล. วิทยาลัยวิทยาศาสตร์และเทคโนโลยีการกีฬาPublication Open Access Effect of HTPB-TAC primer on the bond strength of a resin cement to zirconia.(2558-08) Somchai Urapepon; สมชาย อุรพีพล; Choltacha Harnirattisai; ชลธชา ห้านิรัติศัย; Thanit Soonpan; Mahidol University.

Department of Operative Dentistry and EndodonticsObjective: The purpose of this study was to evaluate the effect of Hydroxyl-terminated polybutadiene grafting with Trimellitic anhydride chloride (HTPB-TAC) primer on microtensile bond strength of a resin cement to zirconia ceramics. Materials... block was cut into 8 microbars (1x1mm). Pool of 48 microbars for each condition was prepared. Half of microbars in each condition were investigated with a microtensile bond strength test. The others were subjected to thermocycling for 10,000 cycles (5Item Metadata only A Study on Self-tapping Design of Cortical Screw for Orthopaedic Application by Using Finite Element Analysis on Pull-out Strength and Bending Strength(2022-11-10) Thongnual P.; Khantachawana A.; Tawonsawatruk T.; Mahidol UniversityOne of the key parameters that determine the performance of the orthopaedic screw is the primary stability such as pull-out strength. The self-tapping flute designs have been adapted to the cortical screw to decrease insertion torque and increase... pull-out strength, but the fluted tip resulted in decreasing of the screw strength. Therefore, this research was to study the different designs of the self-tapping screw. This study will use finite element analysis to determine the most appropriatePublication Metadata only Effect of thermocycling on shear bond strength of the three no-mixed bonding adhesives(2014-01-01) Surachai Dechkunakorn; Niwat Anuwongnukroh; Jirawat Arunakol; Peerapong Tua-Ngam; Mahidol University© (2014) Trans Tech Publications, Switzerland. To investigate the effect of thermocycling on the shear bond strength of the three nomixed bonding adhesive. One hundred and twenty human premolar teeth attached with metal bracket were used... strength and another at 24 hours after thermocycling following the procedure of adhesive. The three-point bending test was performed to test the shear bond strength of each condition. Descriptive analysis was used to calculate the shear bond strengthPublication Metadata only Effect of post-curing temperature and mechanical surface treatment on shear-bond strength of asbestos-free brake pad(2017-01-01) Danuwat Pupan; Chakrit Suvanjumrat; Watcharapong Chookaew; Mahidol University© 2017 Trans Tech Publications, Switzerland. Brake pad is the combination of lining and metallic components, e.g. steel backing plate (disc brake) and aluminum brake shoe (drum brake). Shear bond strength plays a major role to provide the safety... and/or drive performances. This work aimed to study the processing factors affected the bonding strength. The molding temperature couple with post-curing temperature was simultaneously analyzed in order to optimize the processing temperature.
