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

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.

Common Defect

The article presents the results of an estimation of defectiveness level of sour-milk production (on an example kefir), developed on one of dairy factories of region. To assess the level of defect, statistical methods of control are used - a checklist for the registration of defective products, a control p-chart and Ishikava diagram. The initial data were obtained at the stage of quality control of finished product and entered in the developed form of the control sheet for product defects. The most common defect in the production is established - the leakage of the package, which can be assessed visually, and not with the help of measuring instruments. For evaluation and subsequent analysis of the reasons for the appearance of the established defect, a control p-chart was used on an alternative basis, which makes it possible to control the quality of manufactured products by the number of defective products. As a result of the analysis of the obtained data, it was established that the technological process, from the point of view of statistical forecasting, is acceptable, but this does not mean a high production stability and does not exclude the appearance of defective products. The analysis of the main reasons for the emergence of unsealed packaging products, among them the qualification of personnel, the quality of the used materials and the conditions for their storage, the production environment, compliance with production technology, and others. A subsequent study of the impact of each of these factors will prevent the appearance of defective products and ensure the production of consistently high quality products.

Predetermined Time

The measurement process is the most important part of the production process in the industrial world. Obtaining good measurement results can not be separated from using measuring instruments that are always maintained. Subsequence, the maintenance of calibration procedures must be carried out periodically based on a predetermined time limit. The calibration process is an activity to compare standard quantities between measuring instruments and testers that are in accordance with the measuring instrument and carried out periodically. The implementation of the calibration process often has generates an uneven value where this value is better known as the uncertainty value. This research objective is to determine the uncertainty value of the measuring instrument of a dial indicator using the JIS B 7503 Standard. The calibration can control the quality of the equipment used, and can show whether the tool is feasible or not to be used.

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.
