In recent years, it has been recognized that the seismic wave equation solved with a finite-difference method in time causes a predictable and removable error through the use of so-called time-dispersion transforms. These transforms were thought not to apply to visco-elastic media. However, in this paper we demonstrate that the time-dispersion transforms remain applicable when the visco-elastic wa

The Sikhs have perhaps taken the concept of a sacred scripture much further than any other religious community by treating the Guru Granth Sahib as a living guru. This essay analyzes various religious beliefs and practices by which contemporary Sikhs construct and maintain conceptions of their scripture as a guru with spiritual authority. A distinction is made between religious practices that serv

Do entrepreneurs benefit post their entrepreneurial careers on re-entry into paid employment? An answer to this question provides a career value of engaging in an entrepreneurial career. Results have so far been inconclusive suggesting that we still do not know whether entrepreneurship pays or not. Using job matching as the main theoretical foundation, this study investigates how the returns from

Background: As tumors maintain an inflammatory microenvironment, anti-inflammatory medication can be useful in cancer therapy. We have previously shown an association with improved survival in melanoma for use of the H1-antihistamines desloratadine and loratadine, and here we examine use of H1-antihistamines and breast cancer mortality.Material and methods: We investigated use of the six major H1-

Background Oat bran specifically increases colon butyrate concentrations and could therefore affect the progress of the disease in patients with ulcerative colitis (UC). Methods Patients with UC in remission were enrolled in a controlled multicenter study and randomized to eat oat bran or low-fiber wheat products. Results Ninety-four of the enrolled patients (n = 47 for both groups) completed the

OBJECTIVE: The aim of this exploratory randomised controlled trial (RCT) was to evaluate three different occupation-focused interventions for well older people by estimating effect sizes for leisure engagement and ability in activities of daily living (ADL) and thereby identifying the most effective interventions.METHODS: One hundred and seventy seven persons, 77-82 years old, living alone and wit

The transitions to a low carbon and sustainable society are urgent, but at the current level and pace of action there is a significant risk we will escalate and exceed the goals of the Paris Climate Agreement and fail to achieve the Sustainable Development Goals. By engaging cities, we can build momentum around bottom-up interconnected actions and accelerate societal and technological transitions.

Aircraft maintenance and repair organizations (MROs) have to be competitive and attractive for both existing and new customers. The aircraft ground time at MROs should be as short as possible and cost effective without reducing the quality of the work. Process optimization in MROs requires the continuous improvement of processes and the elimination of non-value-added activities during maintenance

The topic of this paper is the application of abrasive flow machining (AFM) to gear tool inserts polishing. Polished surface on plastic gear teeth improves surface geometry stability, and it increases the lifespan, which was proved on the gear testing rig. Experiments have shown that it is an efficient alternative to the hand polishing procedure. Besides significant cost and processing time saving

BACKGROUND/AIMS: Difficulties with bathing are frequent among older people and are associated with an increasing need for societal support. As loss of independence has a negative impact on health and wellbeing, it is important to study interventions that can provide the required support for people to be able to remain independent. Occupational therapy interventions can improve clients' abilities e
