Determination of the strong vertices of doubly heavy baryons with pseudoscalar mesons in QCD

The strong coupling constant of doubly heavy baryons with light pseudoscalar mesons $\pi$ and $K$ are computed within the light cone sum rules. We take into account two-particle and three-particle distribution amplitudes of the said pseudoscalar mesons. We compare our result with the one existing in the literature

Verification and Validation of Semantic Annotations

In this paper, we propose a framework to perform verification and validation of semantically annotated data. The annotations, extracted from websites, are verified against the schema.org vocabulary and Domain Specifications to ensure the syntactic correctness and completeness of the annotations. The Domain Specifications allow checking the compliance of annotations against corresponding domain-specific constraints. The validation mechanism will detect errors and inconsistencies between the content of the analyzed schema.org annotations and the content of the web pages where the annotations were found.Comment: Accepted for the A.P.

Exponential Type Complex and non-Hermitian Potentials in PT-Symmetric Quantum Mechanics

Using the NU method [A.F.Nikiforov, V.B.Uvarov, Special Functions of Mathematical Physics, Birkhauser,Basel,1988], we investigated the real eigenvalues of the complex and/or $PT$- symmetric, non-Hermitian and the exponential type systems, such as Poschl-Teller and Morse potentials.Comment: 14 pages, Late

Polynomial Solution of Non-Central Potentials

We show that the exact energy eigenvalues and eigenfunctions of the Schrodinger equation for charged particles moving in certain class of non-central potentials can be easily calculated analytically in a simple and elegant manner by using Nikiforov and Uvarov (NU) method. We discuss the generalized Coulomb and harmonic oscillator systems. We study the Hartmann Coulomb and the ring-shaped and compound Coulomb plus Aharanov-Bohm potentials as special cases. The results are in exact agreement with other methods.Comment: 18 page

Efficacy of ivabradin to reduce heart rate prior to coronary CT angiography: Comparison with beta-blocker

PURPOSE: The objective of our study was to assess the effect of ivabra-dine on image quality of ECG-gated multidetector computed tomography (MDCT) coronary angiography. MATERIALS AND METHODS: Computed tomography coronary angiography (CTCA) was performed on two groups. In Group 1 (n=54), an intravenous beta-blocker was administered to patients with a heart rate >70 beats per minute (bpm) just before CTCA. In Group 2 (n=56), oral ivabradine 5 mg was administered twice a day for three days prior to CTCA examination to patients with a heart rate >70 bpm and contraindication to beta-blockers. Images acquired on two different MDCT scanners were scored in terms of image quality of the coronary artery segments using a 5-point grading scale (Grade 1, unreadable; Grade 5, excellent). RESULTS: The mean heart rates during CTCA were 64±6.7 bpm for Group 1 and 59±4.1 bpm for Group 2 (P < 0.05). Mean heart rate reduction was 9±5% and 14±8% for Groups 1 and 2, respectively (P < 0.001). A total of 880 segments were evaluated in 110 patients. When the best reconstruction interval was used, 89.8% and 95.5% of all the coronary segments showed acceptable image quality in Groups 1 and 2, respectively. Acceptable image quality of the middle right coronary artery was obtained in 78.3% of Group 1 and 92.4% of Group 2. These ratios for the other segments were 88.4% for Group 1 and 95.2% for Group 2. CONCLUSION: Reduction of heart rates with ivabradine premedication improves the image quality of CTCA. It should be considered as an alternative drug, particularly in patients with contraindications to beta-blockers. © Turkish Society of Radiology 2012

Tail biting in pigs: a multi-causal behavioural disorder

Grizenje repova poremećaj je ponašanja svinja, multikauzalne prirode, a smatra se da motivacija za grizenje proizlazi iz nemogućnosti izražavanja vrsti specifičnog ponašanja (rovanje ili žvakanje). Stoga, životinje preusmjeravaju svoje ponašanje na druge objekte koji su im na raspolaganju, kao što su primjerice uške ili repovi drugih životinja. Grizenje repova izrazito je raširena pojava u uzgoju svinja koja stvara velike ekonomske gubitke i utječe na dobrobit životinja. Ovaj poremećaj ponašanja svinja ima najmanje tri različita polazišta na osnovi kojih se dijeli na tri osnovna oblika. Prvi je oblik ‘dvofazno ili dvo-stupanjsko grizenje’, a kako mu i samo ime govori, sastoji se od dvije odvojene faze. U prvoj fazi svinja nježno drži rep druge u ustima bez da izazove bilo kakvo vidljivo oštećenje tkiva. Tada proces prelazi u drugu fazu, pri čemu ozljeda na repu i posljedično krvarenje privlači i druge životinje iz skupine te naglo dolazi da eskalacije poremećaja ponašanja. Drugi oblik naziva se ‘iznenadno-snažno grizenje’, i kod njega dolazi do naglog i snažnog napada jedne svinje na rep druge svinje. Kod ovog oblika poremećaja odmah dolazi do većih ozljeda, s mogućim djelomičnim ili potpunim gubitkom repa te se ovaj oblik grizenja vrlo često determinira kao kanibalizam. Treći se oblik ovog poremećaja u ponašanju naziva „opsesivno grizenje“. On podrazumijeva snažno i stalno grizenje repova od strane jedne ili nekoliko životinja u skupini. Životinje koje pokazuju ovaj oblik ponašanja stalno su u potrazi za žrtvom te iz tog razloga ovaj oblik grizenja rezultira vrlo brzo do većeg broja ozljeda. Kao mogući uzroci ovog poremećaja spominju se zdravstveno stanje, neodgovarajući uvjeti držanja i nedostatna, odnosno nepravilna hranidba, a kao ne manje važni čimbenici spominju se spol, stres, dosada i genetska predispozicija. Usporedba podataka iz različitih do sad provedenih istraživanja otežana je zbog neujednačene terminologije i različitih načina definiranja ovog poremećaja ponašanja. Ovaj pregledni rad predstavlja aktualni pregled literaturnih saznanja o grizenju repova u svinja, i razmatra različite čimbenike okoliša i uzgoja koji mogu utjecati na njegovo izražavanje i složenost.Tail biting is a multi-causal behavioural disorder in pigs. It is considered that the motivation behind it comes from the pig’s inability to express its species-specific behaviour, such as rooting or chewing. Therefore, animals redirect their behaviour onto other objects available to them, such as the ears or tails of other animals. Tail biting is a widespread phenomenon in breeding pigs, causing great economic losses and affecting the welfare of animals. This behavioural disorder has at least three different starting points, based on which it can be divided into three basic forms. The first is called ‘two-stage biting’, where in the first stage the pig gently holds the tail in the mouth and manipulates it without causing any visible tissue damage. This process proceeds to the second stage, where tail injury and consequent bleeding attracts other animals from the group, when the disorder suddenly escalates. The second form is called ‘sudden-strong biting’, and it is manifested as a sudden and strong attack of one pig against the tail of another. This form of the disorder results in immediate injuries, with possible partial or complete loss of the tail. This form of biting is often determined as cannibalism. The third form of this behavioural disorder is called ‘obsessive biting’. It implies strong and consistent biting of tails by one or several animals in the group. Animals that show this form of behaviour are constantly in search of a victim, and for this reason, this form of tail biting quickly results in a great number of injuries. Possible causes for the development of this disorder include a range of factors, such as health status, inadequate housing, boredom, gender, stress, genetics and insufficient or improper nutrition, as outlined in the literature. Comparison of data from different studies has been hampered by the lack of uniform terminology and the many different definitions of this disorder. This review presents the current findings on the tail-biting phenomena in pigs, and consider the various factors of the environment and husbandry that can affect its expression and complexity

Explaining the decline in coronary heart disease mortality in Turkey between 1995 and 2008.

BACKGROUND: Coronary heart disease (CHD) mortality rates have been decreasing in Turkey since the early 1990s. Our study aimed to determine how much of the CHD mortality decrease in Turkey between 1995 and 2008 could be attributed to temporal trends in major risk factors and how much to advances in medical and surgical treatments. METHODS: The validated IMPACT CHD mortality model was used to combine and analyse data on uptake and effectiveness of CHD treatments and risk factor trends in Turkey in adults aged 35-84 years between 1995 and 2008.Data sources were identified, searched and appraised on population, mortality and major CHD risk factors for adults those aged 35-84 years. Official statistics, electronic databases, national registers, surveys and published trials were screened from 1995 onwards. RESULTS: Between 1995 and 2008, coronary heart disease mortality rates in Turkey decreased by 34% in men and 28% in women 35 years and over. This resulted in 35,720 fewer deaths in 2008.Approximately 47% of this mortality decrease was attributed to treatments in individuals (including approximately 16% to secondary prevention, 3% angina treatments, 9% to heart failure treatments, 5% to initial treatments of acute myocardial infarction, and 5% to hypertension treatments) and approximately 42% was attributable to population risk factor reductions (notably blood pressure 29%; smoking 27%; and cholesterol 1%). Adverse trends were seen for obesity and diabetes (potentially increasing mortality by approximately 11% and 14% respectively). The model explained almost 90% of the mortality fall. CONCLUSION: Reduction in major cardiovascular risk factors explained approximately 42% and improvements in medical and surgical treatments explained some 47% of the CHD mortality fall. These findings emphasize the complimentary value of primary prevention and evidence-based medical treatments in controlling coronary heart disease
