An optimised, multi-chamber, micro-perforated panel absorber (MC-MPPA) with adjoining panels is presented in this paper. MPPA a clean and efficient noise simple structure making it an increasingly popular choice over porous material-based solutions. For the basic configuration, bandwidth typically limited by perforation size frequency range backing cavity depth. In order to improve these parame...
Options for skin cancer treatment currently include surgery, radiotherapy, topical chemotherapy, cryosurgery, curettage, and electrodessication. Although effective, surgery is costly and unsuitable for certain patients. Radiotherapy can leave a poor cosmetic effect, and current chemotherapy is limited by low cure rates and extended treatment schedules. Here, we describe the preclinical activity...
Amidst continuing difficulties in justifying the expenditure on e-Government with financial and other returns, we examine whether the delivery of government services online facilitates the setting up of new businesses in a country. Using a panel assembled from three public sources of data, we examine whether delivering more and more government services online reduces the number of procedures th...
Due to the lack of consistent data, direct and robust comparisons of cross-country labour markets have been virtually impossible. This study uses a new panel data series that controls for inconsistencies, thus overcoming this problem. This study estimates gender wage differentials and gender discrimination in the German and United Kingdom labour markets. Panel estimates are used to identify gen...

The aim of this paper is to explore how interpersonal variation in risk preference affects human capital investment and wage growth. To date, there has been a distinct lack of empirical research in this area despite the fact that the risk preference of individuals plays a key role in the theory of human capital accumulation. We investigate the link between risk preference, human capital investm...
The advantages, disadvantages, and issues involved in the panel analysis of travel behavior are discussed. Increased statistical efficiency, possibility of improved prediction, and the ability to observe changes and examine behavioral dynamics, are among the advantages panel data offer. Their disadvantages, on the other hand, stem from the added biases and costs of panel survey, and increased c...
many mobile and off-grid devices include electronics and other electrical consumers like servo drives, which need a quite low supply power. since the price for photovoltaic modules drops continuously, photovoltaic power supply is interesting in more and more applications. in solar powered systems, a battery is needed to store energy for the night and cloudy periods. the power electronics of suc...
Abstract Background Findings from recent clinical outcome trials have raised concerns regarding potential off target adverse effects supplementation with n-3 polyunsaturated fatty acids (PUFA) on atrial fibrillation (AF) risk. Purpose We aimed to assess AF and “micro-AF” in elderly patients myocardial infarction (MI), randomized PUFA or placebo. Methods In the OMEMI trial, 70–82 years old a MI ...
