AbstractThe PLAnetary Transits and Oscillations of stars (PLATO) mission is in its definition study phase in the context of ESA's Cosmic Vision 2015-2025 program. PLATO is applying for a launch in 2017/18. Its goal is to detect transiting exoplanets, including terrestrial planets in the habitable zone, and to determine their basic parameters with unprecedented accuracy. In combination with the detailed analysis of the stellar parameters by astroseismology and with ground-based follow-up observations, this will allow characterizing the main properties of exoplanetary systems to a level not achieved before.

AbstractPLATO (PLAnetary Transits and Oscilliations of stars) is a proposed mission of the European Space Agency's Science programme Cosmic Vision 2015–2025, currently under industrial study, and with a planned launch by the end of 2017. Its task is to better understand the properties of exoplanetary systems. As such it will detect and characterise exoplanets using their transit signature in front of a large sample of bright stars and simultaneously measuring the seismic oscillations of the parent star of these exoplanets. The mission will be orbiting the Sun-Earth L2 point, which provides a stable thermal environment and maximum uninterrupted observing efficiency. The payload consists of a number (> 28) of individual catadioptric telescopes, covering > 550 sq. degrees. Since the goal is to search for terrestrial exoplanets within the habitable zone of their host stars, and carry out asteroseismological observations of the host stars, very high photometric precision, high time resolution, and high duty-cycle visible photometry is required. Ground-based observations are needed to complement the observations made by PLATO to allow for further exoplanetary characterization. This paper consists of a summary of the preliminary results achieved by the ESA internal pre-assessment study.

Abstract Background Patients with cardiovascular diseases (CVD) are treated over a long period of time by physicians and therapists from various institutions collaborating within a multidisciplinary team. Usually, medical records detailing the diagnoses and treatment regimens are long and extensive. Brief overviews of relevant diagnostic and treatment data in the form of a patient passport are currently missing in routine care for patients with CVD. This study aimed to develop and evaluate a patient passport (the Kardio-Pass) based on the needs of patients who had undergone cardiac rehabilitation, and of healthcare professionals. Methods A mixed method design was adopted consisting of an explorative qualitative phase followed by a quantitative evaluation phase. Interviews with patients and experts were conducted to develop the Kardio-Pass. CVD rehabilitees (N = 150) were asked to evaluate the passport using a semi-standardized written questionnaire. Results Patients and experts who were interviewed in the qualitative study phase considered the following passport contents to be particularly important: documentation of findings and diagnoses, cardiac diagnostics and intervention, medication plan, risk factors for heart disease, signs of a heart attack and what to do in an emergency. During the evaluation phase, 93 rehabilitees (response rate: 62%) completed the questionnaire. The Kardio-Pass achieved high overall approval: All respondents considered the information contained in the passport to be trustworthy. The professionalism and the design of the passport were rated very highly by 93 and 92% of participants, respectively. Use of the Kardio-Pass prompted 53% of participants to regularly attend follow-up appointments. The most common reasons for non-use were a lack of support from the attending doctor, failure by the patient to make entries in the passport, and loss of the passport. Conclusions By documenting the course of cardiac diseases, the patient passport pools all medical data–from diagnosis to treatment and aftercare–in a concise manner. Rehabilitees who used the cardiac passport rated it as a helpful tool for documenting follow-up data. However, with regard to this explorative study there is a need for further research, particularly on whether the patient passport can improve heart patient care.

AbstractWe investigate the angular momentum distribution of known exoplanetary systems, as a function of the planetary mass, orbital semimajor axis and metallicity of the host star. We find exoplanets seems to be classified according to at least two ‘populations’, with respect to their angular momentum properties. This classification is independent on the composition of the planet and seems to be valid for both jovian and neptunian planets, and probably can be extrapolated to the terrestrial planets of the Solar System. We analyse these ‘populations’ considering the phenomenon of planetary migration.

Objective:<b> </b>To determine whether<b> </b>angiotensin converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARB) protect against lower respiratory tract infections complicating type 2 diabetes. <p>Research design and methods:<b> </b>Of 1,732 participants with diabetes recruited to the longitudinal observational Fremantle Diabetes Study Phase II (FDS2) between 2008 and 2011, 1,482 had confirmed type 2 diabetes (mean age of 65.8 years, 51.6% were males, median diabetes duration 9.0 years). All were followed for hospitalizations for/with, or deaths from, pneumonia/influenza ascertained from validated administrative data linkage from study entry to end-2016.

Allowing for the competing risk of death did not change this finding (subdistribution HR 0.67 (0.48, 0.95), <i>P</i>=0.024), and similar reductions were seen for ACEi, ARB alone, and ACEi/ARB combination therapy.

The organizational project management control has been the area of great interest from long time among the investigators who validated that there is a great necessity of control approaches in an organization to acquire their goals. In this paper, a detailed analysis describing the stages associated with control in project management process has been illustrated. In the first phase the proposed plans are outlined with a follow up on the deviation of the plans with causes. In the final phase a detailed solution analysis was carried on what the company did to fix the series of delays along with some suggestions stating proper ways of dealing the situations. This research gives a wide overview on the problems that 787 Dreamliner faced during its manufacturing and delivery process. The analysis was done on the control perspective. Innovative solutions was laid down which if applied during the service procedures could have avoided the problems related to delay of 787 Dreamliner’s delivery. The main intention of this research is that the solutions and strategies provided can be implemented successfully to the other organization for better planning and handling of entire process ultimately minimizing the downtime and increasing the productivity of the organization.
