An astrometric and spectroscopic study of the δ\delta Scuti variable HD21190 and its wide companion CPD -83∘^{\circ} 64B

Although pulsations of $\delta$ Scuti type are not expected among Ap stars from a theoretical point of view, previous observations of the known $\delta$ Scuti star HD21190 indicated a spectral classification F2 III SrEuSi:, making it the most evolved Ap star known. Our atmospheric chemical analysis based on recent HARPS observations confirms the presence of chemical peculiarities in HD21190. This star is also the only target known to host a magnetic field along with its $\delta$ Scuti pulsation properties. Using an astrometric analysis, we show that HD21190 forms a physical binary system with the companion CPD -83$^{\circ}$ 64B. The presented astrometric and spectroscopic study of the binary components is important to understand the complex interplay between stellar pulsations, magnetic fields, and chemical composition.Comment: 16 pages, 9 figures, 4 table

Combined burden and functional impact tests for cancer driver discovery using DriverPower

The discovery of driver mutations is one of the key motivations for cancer genome sequencing. Here, as part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium, which aggregated whole genome sequencing data from 2658 cancers across 38 tumour types, we describe DriverPower, a software package that uses mutational burden and functional impact evidence to identify driver mutations in coding and non-coding sites within cancer whole genomes. Using a total of 1373 genomic features derived from public sources, DriverPower's background mutation model explains up to 93% of the regional variance in the mutation rate across multiple tumour types. By incorporating functional impact scores, we are able to further increase the accuracy of driver discovery. Testing across a collection of 2583 cancer genomes from the PCAWG project, DriverPower identifies 217 coding and 95 non-coding driver candidates. Comparing to six published methods used by the PCAWG Drivers and Functional Interpretation Working Group, DriverPower has the highest F1 score for both coding and non-coding driver discovery. This demonstrates that DriverPower is an effective framework for computational driver discovery

European overview of sustainable policies and approaches in COST C25 member countries

The implementation of the principles and methods towards a Sustainable Construction varies across different countries in Europe. In some countries, the sustainability of the construction sector has been effectively taken into consideration over the last years, while in other its implementation is at an initial stage. Many reasons may be pointed out for this situation. Different countries have different understandings of what is entailed in Sustainable Construction. Different cultural and educational backgrounds, along with different priorities in each country, are also contributing for the lack of a common European approach. General frameworks, aiming to cover every aspect of Sustainable Construction and to provide a consistent and integrated approach, such as Agenda 21 for Sustainable Construction, gave a major advance in the search for a common approach for the construction sector. However, general agreed methodologies and tools to make this common approach operational are still missing.European Science Foundation - COST Action C2

In-depth study of moderately young but extremely red, very dusty substellar companion HD206893B

Accepted for publication in Astronomy & Astrophysics. Reproduced with permission from Astronomy & Astrophysics. © 2018 ESO.The substellar companion HD206893b has recently been discovered by direct imaging of its disc-bearing host star with the SPHERE instrument. We investigate the atypical properties of the companion, which has the reddest near-infrared colours among all known substellar objects, either orbiting a star or isolated, and we provide a comprehensive characterisation of the host star-disc-companion system. We conducted a follow-up of the companion with adaptive optics imaging and spectro-imaging with SPHERE, and a multiinstrument follow-up of its host star. We obtain a R=30 spectrum from 0.95 to 1.64 micron of the companion and additional photometry at 2.11 and 2.25 micron. We carried out extensive atmosphere model fitting for the companions and the host star in order to derive their age, mass, and metallicity. We found no additional companion in the system in spite of exquisite observing conditions resulting in sensitivity to 6MJup (2MJup) at 0.5" for an age of 300 Myr (50 Myr). We detect orbital motion over more than one year and characterise the possible Keplerian orbits. We constrain the age of the system to a minimum of 50 Myr and a maximum of 700 Myr, and determine that the host-star metallicity is nearly solar. The comparison of the companion spectrum and photometry to model atmospheres indicates that the companion is an extremely dusty late L dwarf, with an intermediate gravity (log g 4.5-5.0) which is compatible with the independent age estimate of the system. Though our best fit corresponds to a brown dwarf of 15-30 MJup aged 100-300 Myr, our analysis is also compatible with a range of masses and ages going from a 50 Myr 12MJup planetary-mass object to a 50 MJup Hyades-age brown dwarf...Peer reviewedFinal Accepted Versio

Bycatch in 36 and 40 mm PA Turkish twin rigged beam trawl codends

The Turkish twin rigged beam trawl which has two identical nets rigged side by side on the same beam targets mainly the Parapenaeus longirostris, although some bycatch fish species have also become target species. Thus, landings of the shrimp beam trawling fleet also include some commercially valuable fishes. Our study focused on the bycatch commercial species which are caught by the beam trawl fishery with nominal mesh sizes 36 and 40 mm PA (diamond) codend in the Sea of Marmara (Turkey) and also on the minimum landing size (MLS) established for Merluccius merluccius, Merlangius merlangus euxinus, Mullus surmuletus, Trachurus trachurus and Pomatomus saltatrix. Since there was no MLS value for Spicara smaris, the length at first maturity (LFM) was used for this species. Experiments were carried out onboard the commercial beam trawler. In 20 hauls, the average codend catch weight was 63.12 kg for 36 mm PA and 66.51 kg for 40 mm PA. On the other hand, for 36 mm PA, 83.5% of M. merluccius, 74.3% of M. merlangus euxinus, 29.7% of T. trachurus, 10.8% of P. saltatrix and 8.6% of M. surmuletus were below the MLS. For 40 mm PA, 88.9% of M. merlangus euxinus, 87.7% of M. merluccius, 42.5% of T. trachurus, 7.2% of P. saltatrix and 6.7% of M. surmuletus were below MLS. In addition, 7.5% of S. smaris were below length at first maturity (LFM) for 36 PA codends.Key words: Beam trawl, rose shrimp, Parapenaeus longirostris, bycatch, discards, minimum landing size, Sea of Marmara, Turkey

Investigation of Serum allergen-specific IgE concentrations in feline asthma: a clinical experience

The aim of this study is to investigate allergen agents by allergen-specific serum IgE analysis in domestic cats diagnosed with feline asthma (FA). A total of 21 cats (16 FA and 5 control cats) were included in the study. Allergen-specific serum IgE levels were measured in cats diagnosed with feline asthma and in the control group. Allergen levels were classified as negative, weak, moderate and strong. The difference between the two groups was compared statistically. While the mean age of the cats in the FA group was 3.9kg ±2.4 years, the mean age of the cats in the control group was 3.4±2.2 years. The most common clinical manifestations in cats with FA were cough, sneezing, wheezing, and acute dyspnea, respectively. Allergen-specific IgE levels tested for 20 different allergens showed that 14 out of 16 cats developed a reaction to more than one allergen. The vast majority of cats with FA had a moderate or strong positive reaction to house dust mites. In conclusion, FA is an important and common chronic lower respiratory tract disease of feline patients and allergen-specific serum IgE levels can be easily used in clinical practice to guide the selection of allergens in the treatment of this disease and adjust for the quality of life and well-being of cats

Planetary bearing defect detection in a commercial helicopter main gearbox with vibration and acoustic emission

The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link.Helicopter gearboxes significantly differ from other transmission types and exhibit unique behaviors that reduce the effectiveness of traditional fault diagnostics methods. In addition, due to lack of redundancy, helicopter transmission failure can lead to catastrophic accidents. Bearing faults in helicopter gearboxes are difficult to discriminate due to the low signal to noise ratio (SNR) in the presence of gear vibration. In addition, the vibration response from the planet gear bearings must be transmitted via a time-varying path through the ring gear to externally mounted accelerometers, which cause yet further bearing vibration signal suppression. This research programme has resulted in the successful proof of concept of a broadband wireless transmission sensor that incorporates power scavenging whilst operating within a helicopter gearbox. In addition, this paper investigates the application of signal separation techniques in detection of bearing faults within the epicyclic module of a large helicopter (CS-29) main gearbox using vibration and Acoustic Emissions (AE). It compares their effectiveness for various operating conditions. Three signal processing techniques including an adaptive filter, spectral kurtosis and envelope analysis, were combined for this investigation. In addition, this research discusses the feasibility of using AE for helicopter gearbox monitoring

DIAGNOSIS OF PERSISTENT BVD IN ONE DAY OLD AND OLDER THAN 30 DAYS CALVES WITH RAPID KIT TESTS

Bovine Viral Diarrhoea (BVD) is an important disease of cattle which causes alimentary, respiratory and reproductive disorders and serious economic losses. Today, eradication of disease is compulsory for the increase of dairies and achieving more healthier herds. In cattle, if the calves are infected with BVD from the uterus in the first trimester of pregnancy, they are born persistent infected (PI) antigen(+). The PI calves are smaller or normal in apperance than normal calves. Persistent infected (PI) calves spread the virus throughout their lives and infect their surroundings. BVD causes early embrionic death, calves born with anomalies and immunosuppression in infected animals. In this study 200 calves between 1–30 days old from Burdur province are screened with BVD rapid test kit. In the screening, 13 calves (6.5%) are found BVDV ag(+). The gender of PI calves are found 4% female (8/200) and 2.5% male (5/200). In the 5% of PI calves (10/200), respiratory and alimentary problems were clinically seen. The antigen(+) animals are put out of the herd and vaccination protocols are recommended. In this study, diagnosing the disease can be made rapidly by both clinicians and farmers, also putting the virus spreading persistent calves out of herd without losing time and a successful struggle can be made against BVD, are shown
