The Impact

Optimization of process conditions in oriented strand board (OSB) manufacturing is a very important issue for both reducing cost and improving the quality of panels. Taguchi experimental design technique was applied to determination and optimization of the most influential controlling parameters of OSB panels such as press condition (pressure-time-temperature) and the ratio of adhesive parameters on modulus of elasticity (MOE). The value of the MOE is one of the very important mechanical properties of OSB panels. For this purpose, several experiments were conducted according to Taguchi L27 orthogonal design. The signal-to-noise (S/N) and the analysis of variance (ANOVA) were used to find the optimum levels and to indicate the impact of the controlling parameters on MOE. A verification test was also performed to prove the effectiveness of Taguchi technique. Since the predicted and the measured values were very close to each other, it was concluded that the Taguchi method was very successful in the optimization of effective parameters in OSB’s manufacturing.

Taguchi Orthogonal Design

This paper investigates the application of a Taguchi method to reduce warpage problem dealing with process parameters during production of bonding sheets. For this purpose, analysis was carried out by utilizing a combination of process parameters based on a two-level L12 Taguchi orthogonal design. The signal-to-noise and the analysis of variance are used to find the optimum levels and to indicate the impact of the process parameters on warpage. The results show that the method can reduce warpage by about 94%, and a verification test is also conducted to prove its effectiveness after the optimum levels of process parameters are determined. It can thus be concluded that this Taguchi method is suitable to solve the quality problems that occur due to warpage.

The Impact

Oriented strand board (OSB) is a commonly used structural wood-based panel for walls and roof siding, but recently the industry has become interested in OSB as a substrate for indoor and outdoor furniture. Particleboard is mainly used in furniture productions and has become popular as a construction material due to its numerous usage possibilities and inexpensive cost. Moisture is one of the most important factors affecting wood-based panel performance and the post-treatment conditions affected their affinity to water. When OSB and particleboard are used as substrates for coatings, their surface characteristics play an important role in determining the quality of the final product. Furthermore, roughness can significantly affect the interfacial phenomena such as adsorption, wetting, and adhesion which may have an impact on the coating performance. In this research particleboard and OSB panels were sanded, re-pressed and IR heated and the influence of surface treatments on hardness, roughness, wetting, water, and water vapour absorption was studied. Results showed that sanding improved the wetting of particleboard and OSB with water. Moreover, studied surface treatments increased water absorption and water penetration depth of OSB panels, and re-pressing had a positive effect on reducing the water vapour absorption of particleboard and OSB panels.

The Impact

The objective of this study is to analyze the main parameter setting in injection moulding that influenced the processing of selected thermoplastics components. The test sample used for this project was a hinge made from Polypropylene (PP). This sample was being utilised to analyse the parameters affecting the quality of plastic products, which were warpage and shrinkage. Computer-Aided Engineering (CAE) was applied through CadMould 3D-F simulation software. The processing parameters such as filling time, melt temperature, wall temperature and cooling time were selected to determine the quality of the product. By adopting Taguchi Method, the orthogonal array, Signal-to-Noise (S/N) ratio and Analysis of Variance (ANOVA) were used to find the optimum levels as well as to indicate the impact of the process parameters on warpage and shrinkage. The verification test was also performed to prove the effectiveness of Taguchi technique after the optimum levels of process parameters. The ANOVA results show that cooling time and wall temperature are found to be the most significant factors for shrinkage and warpage, with the contribution of 66.96% and 56.82% respectively. The verification test with the optimal settings shows that warpage were improved by about 0.4% and shrinkage with 4.2% improvement. These findings are useful for production engineer to determine optimal parameter during performing injection moulding on hinges products.

Systematic Control

Proper and systematic control of the odorization process is a basic condition for ensuring public safety in the distribution and use of gaseous fuels and for the continuity of the process. Maintaining a constant level of gas odorization requires gas network operators to constantly monitor the odorizing process. The control is carried out, among others by measuring the concentration of odorant in the gas. This is an important and inseparable element of controlling the degree of odorization of gaseous fuels, aimed at controlling the operation of odorizing devices by verifying the dose of odorizing agent or controlling the composition of gaseous fuel at any point of the gas distribution network. The correctness of uninterrupted control of the degree of gas odorization depends on the availability and quality of measuring instruments. The only process chromatographic analyzer intended for continuous measurement of the odorant concentration in gaseous fuels used on a national scale is the ANAT-M analyzer. Since this device works under process conditions, not supervised by an analyst, it is extremely important to recognize the restrictions on the correctness of its indications resulting from the presence of certain compounds in the gas. The article presents the analysis of observations and results of analyzes regarding the impact of selected sulfur compounds and other components of high-methane natural gas on the response of the THT detector currently used in ANAT-M analyzers. The significance of this influence for the quality of obtained THT concentration measurement results was determined. Gases containing sulfur compounds that may be present in the network gas, such as hydrogen sulfide, methyl mercaptan, dimethyl sulfide, as well as network gas containing the addition of LNG and biogas gases were tested. The obtained test results were analyzed in terms of determining the magnitude of the impact of the tested parameters on the precision of measurements performed with the ANAT-M analyzer.

The Impact

As a kind of promising lightweight material, CFRP (Carbon Fiber Reinforcement Polymers) have been widely concerned in automobile industry in last decades. In the present work, series of experiments are conducted to investigate the impact of key process conditions, including the cutting edge geometry, curing process and cutting manner, on the CFRP cross-sections quality by cutting at resin infiltration during implementing the CFRP parts integrated manufacturing processes based on RFI process. For the typical cross-section defect such as the debunching of carbon fiber, chippings of carbon fiber and resin salivation, authors explain why that happens and propose the corresponding suppressing measures. Research results show that, under the existing experimental conditions, the optimal process scheme is to combine the large arc edge with curing before punch returns back and press cutting to obtain the desired CFRP cross-sections.

The Impact

Development of biotherapeutics require pharmacokinetic/pharmacodynamic (PK/PD) and immunogenicity assays that are frequently in a ligand-binding assay (LBA) format. Conjugated critical reagents for LBAs are generated conjugation of the biotherapeutic drug or anti-drug molecule with a label. Since conjugated critical reagent quality impacts LBA performance, control of the generation process is essential. Our perspective is that process development methodologies should be integrated into critical reagent production to understand the impact of conjugation reactions, purification techniques and formulation conditions on the quality of the reagent. In this article, case studies highlight our approach to developing process conditions for different molecular classes of critical reagents including antibodies and a peptide. This development approach can be applied to the generation of future conjugated critical reagents.

Purpose The purpose of this study was to identify levels of self-compassion in adults who do and do not stutter and to determine whether self-compassion predicts the impact of stuttering on quality of life in adults who stutter. Method Participants included 140 adults who do and do not stutter matched for age and gender. All participants completed the Self-Compassion Scale. Adults who stutter also completed the Overall Assessment of the Speaker's Experience of Stuttering. Data were analyzed for self-compassion differences between and within adults who do and do not stutter and to predict self-compassion on quality of life in adults who stutter. Results Adults who do and do not stutter exhibited no significant differences in total self-compassion, regardless of participant gender. A simple linear regression of the total self-compassion score and total Overall Assessment of the Speaker's Experience of Stuttering score showed a significant, negative linear relationship of self-compassion predicting the impact of stuttering on quality of life. Conclusions Data suggest that higher levels of self-kindness, mindfulness, and social connectedness (i.e., self-compassion) are related to reduced negative reactions to stuttering, an increased participation in daily communication situations, and an improved overall quality of life. Future research should replicate current findings and identify moderators of the self-compassion–quality of life relationship.

Swallow Function

Lung cancer is one of the most commonly diagnosed cancers across Northern America and Europe. Treatment options offered are dependent on the type of cancer, the location of the tumor, the staging, and the overall health of the person. When surgery for lung cancer is offered, difficulty swallowing is a potential complication that can have several influencing factors. Surgical interaction with the recurrent laryngeal nerve (RLN) can lead to unilateral vocal cord palsy, altering swallow function and safety. Understanding whether the RLN has been preserved, damaged, or sacrificed is integral to understanding the effect on the swallow and the subsequent treatment options available. There is also the risk of post-surgical reduction of physiological reserve, which can reduce the strength and function of the swallow in addition to any surgery specific complications. As lung cancer has a limited prognosis, the clinician must also factor in the palliative phase, as this can further increase the burden of an already compromised swallow. By understanding the surgery and the implications this may have for the swallow, there is the potential to reduce the impact of post-surgical complications and so improve quality of life (QOL) for people with lung cancer.
