It is a phenomenon that an experience mechanical/ design engineer with years of experience in mechanical parts design, still must to improve the knowledge about process design. This phenomenon will be different with other fields but common in process design because design is continuous process. The automotive industry is expected to be one of the driving factors for economic growth in Indonesia in 2025. It is shown by research firm (Frost & Sullivan) that estimates this year's car sales in Indonesia will rise moderately by 6.5% from a year earlier to 948,500 units and the real car sales in Indonesia rose to 43% in April 2012. Development should be increased because the government provides to industrial facilities that conduct research, development and innovation. Therefore the design process until production is expected to be rapid and immediate product can be enjoyed by society. To speed up the production process, the design process should be faster, and account how the next process that is the production. This research useds the form of the usual features carried with three machining processes are widely used in the world of mechanical component industries. The processes are turning (around 24.9% of machining process), milling (around 20.2% of machining process) and drilling (around 28.2% of machining process). The overall mean of the three processes around 73.3% of the portion of the machining process (survey conducted by PERA).

In The Beginning

AbstractA presence of carbonyl compounds is very common in the food industry. The nature of such compounds is to be reactive and thus many products involve aldehydes/ketones in their synthetic routes. By contrast, the high reactivity of carbonyl compounds could also lead to formation of undesired compounds, such as genotoxic impurities. It can therefore be important to remove carbonyl compounds by implementing suitable removal techniques, with the aim of protecting final product quality. This work is focused on benzaldehyde as a model component, studying its removal from a water/ethanol mixture by applying different derivatization agents as the scavengers. Discovery chemistry is performed in the beginning as a screening procedure, followed by the process design of a small-scale continuous process for benzaldehyde removal with in-line real-time monitoring. Applications of tris(hydroxymethyl)aminomethane (TRIS) are found to provide above average removal of benzaldehyde.

Disinfection processes have often been characterized by the “CT” concept i.e., the product of disinfectant residual and contact time (perhaps as a function of pH, temperature, and other water quality variations) produces a given level of disinfection. The objective of this work was to develop and validate the use of reaction kinetic models for disinfection process design. Using bench scale (batch) kinetic information, and hydraulic characterization of pilot scale continuous disinfection processes, predictions of continuous process performance were made using a segregated flow model. These predictions were compared to independent experimental measurements of actual inactivation in pilot scale processes. Preammoniation, free residual chlorination, and ozonation were used on two waters from Portland, Oregon (US). Organisms used were Giardia muris, bacteriophage MS2, and Escherichia coli.

Telephone Service

Ethical dilemmas encountered by psychologists have previously been studied in surveys and as formal ethical complaints. No previous publications have been found in which data from an ethics counseling telephone service for psychologists has been analyzed. The present study examines ethical dilemmas, as presented by members of the Norwegian Psychological Association calling the Ethics Telephone Counseling Service (ETCS) from 2001 through 2003. Psychologists seek counseling for a range of ethical dilemmas. Ethical dilemmas concerning confidentiality are those most commonly presented. Dilemmas concerning integrity are also fairly common, whereas dilemmas concerning competence are rarely presented. The study shows virtually no difference in frequency and nature of consultation based on how long a psychologist has been licensed. This study also shows only minor gender differences in the use of the ETCS. Possible implications for ethics education as a continuous process are discussed.

The article describes experience of creating and implementing information-managing educational environment at university. The model of creating information-managing educational environment of university with elements of artificial intelligence and indicative management is described. This environment contributes to improve quality of training and management of educational processes and resources. The stages of creating and implementing information-managing educational environment are considered systemically, as continuous process focused on a consumer. The inhibitory and facilitating conditions for introduction of the model at university are described. To provide subject-oriented approach to the use of information resources of environment, recommended clusters of information subsystems for each category of users are described.Practically implemented scientific and methodological recommendations for subjects of educational process to overcome resistance to innovations introduced in educational organizations are proposed.Features of adaptation of the developed information-managing educational environment for schools are presented.

This article examines Nancy Huston's writing of female ageing in light of her intellectual and personal trajectory as a feminist thinker. It identifies women's ageing as an integrative and ubiquitous phenomenon in Huston's œuvre, tracing the presence of this thematic and theoretical concern to her very first published works, and outlining its development until her most recent works, before examining a key instance of her fictional treatment of female ageing in Lignes de faille. Drawing on a literary, philosophical and sociological theoretical framework, it argues that Huston furthers feminist approaches to female senescence by inscribing women's experiences of later life not in terms of existential crisis but rather as part of the continuous process of change and transformation inherent to subjective development. The analysis aims to address pressing questions surrounding the intersections of gender and age that are at the forefront of Huston criticism and feminist studies.

In recent years, chronic medical problems have become increasingly prevalent. Chronic ‎illnesses challenge the view of life as a regular and continuous process, a challenge that has ‎important psychological consequences. The long duration of people suffering from these ‎diseases, the long process of treatment and the fact that there is no proper and definitive ‎treatment for most of these diseases and their associated complications have made chronic ‎diseases a detrimental factor in public health. According to the World Health Organization ‎‎(2006), the prevalence of chronic and non-communicable diseases is increasing in all countries, ‎especially developing countries, so that the major challenge for the health system in the present ‎century, is not living people, but better adapted to chronic illnesses and maintaining their ‎mental and social health and well-being Ed's life-threatening chronic physical illness.‎ Chronic pain is a pain that lasts longer than usual, and according to the criteria of the ‎International Association of Pain, this time is defined as at least 3 months to 6 months. Chronic ‎pain is such that not only faced the sick person whit the pressure of the pain but also with many ‎other pressure that affect different parts of her life. Fibromyalgia is one of the most rheumatologic disorders and one of the most resistant chronic ‎pain syndromes. Fibromyalgia is one of the most common musculoskeletal disorders in adults ‎and chronic pain is one of the most common complaints in this group of patients.
