Extra note of music in anaesthesia

Role of music has been identified since ancient times for alleviating anxiety. Music has been known for its potential to produce a sense of wellbeing and peace. Anaesthesia and surgery are major stress factors for any person. Preoperative anxiety is a usual phenomenon in patients posted for various surgical interventions as well as those admitted to intensive care units (ICU). Literature shows ample evidence regarding neurohormonal disturbances related to stressful situations like preoperative, intraoperative and post-operative periods. Music has been shown to attenuate release of various biochemical molecules leading to relaxing and sedative effects on the brain. Not only patients under regional anaesthesia who are awake have a positive impact, even patients under general anaesthesia have also been shown to benefit from listening to music intraoperatively. Music is a hazard free intervention which can be added to various drug combinations used by anaesthesiologists

On the origin of X-shaped radio galaxies

After a brief, critical review of the leading explanations proposed for the small but important subset of radio galaxies showing an X-shaped morphology (XRGs) we propose a generalized model, based on the jet-shell interaction and spin-flip hypotheses. The most popular scenarios for this intriguing phenomenon invoke either hydrodynamical backflows and over-pressured cocoons or rapid jet reorientations, presumably from the spin-flips of central engines following the mergers of pairs of galaxies, each of which contains a supermassive black hole (SMBH). We confront these models with a number of key observations and thus argue that none of the models is capable of explaining the entire range of salient observational properties of XRGs, although some of the arguments raised in the literature against the spin-flip scenario are probably not tenable. We then propose here a new scenario which also involves galactic mergers but would allow the spin of the central engine to maintain its direction. Motivated by the detailed multi-band observations of the nearest radio galaxy, Centaurus A, this new model emphasizes the role of interactions between the jets and the shells of stars and gas that form and rotate around the merged galaxy and can cause temporary deflections of the jets, occasionally giving rise to an X-shaped radio structure. Although each of the models is likely to be relevant to a subset of XRGs, the bulk of the evidence indicates that most of them are best explained by the jet-shell interaction or spin-flip hypotheses.Comment: 19 pages, major revision including two Appendices and a Table, accepted in Research in Astronomy and Astrophysic

CGCG 292-057 - a radio galaxy with merger-modulated radio activity

We announce the discovery of a unique combination of features in a radio source identified with the merger galaxy CGCG 292-057. The radio galaxy both exhibits a highly complex, X-like structure and shows signs of recurrent activity in the form of double-double morphology. The outer lobes of CGCG 292-057 are characterized by low radio power, P_{1400MHz} \simeq 2 * 10^{24} W\Hz^{-1}, placing this source below the FRII/FRI luminosity threshold, and are highly polarized (almost 20 per cent at 1400 MHz) as is typical of X-shaped radio sources. The host is a LINER-type galaxy with a relatively low black hole mass and double-peaked narrow emission lines. These features make this galaxy a primary target for studies of merger-triggered radio activity.Comment: 7 pages, 5 figures, submitted to MNRA

Stability analysis of yield, yield attributes and essential oil content in fennel (Foeniculum vulgare Mill.) evaluated under a long-term organic production system

Eight varieties of fennel (Foeniculum vulgare Mill.) were evaluated under field trial for their stability of yield, yield attributes and essential oil content under the organic production system in six consecutive years from 2016 to 2021. Mean square due to environment + (variety × environment) was significant for all the traits studied indicating the existence of variety × environment interaction. Based on the mean performance, regression coefficient and deviation from regression values, it was found that stability of yield and yield components are imparted in the varieties, GF-12 and AF-1 across the years through the stable performance of characters and like numbers of primary and secondary branches, number of umbels and umbellate and seed yield. However, variety RF-101 for essential oil content can be considered as most suitable, stable and adopted to organic production system compared to other varieties. Correlation analysis revealed highly positive relationship in plant height, number of primary branches, number of umbels and umbellate per plant and seed yield. Based on the findings, fennel growers are apprised to select stable high-yielding fennel varieties for the organic production systems in semi-arid regions of India. Along with their use in hybridization programmes to converge the stability characteristics of seed yield for the development of a stable variety adapted to a wider range of environments under organic production systems

Black hole masses and starbursts in X-shaped radio sources

It has been suggested that the X-shaped morphology observed in some radio sources can reflect either a recent merger of two supermassive black holes (SMBHs) or the presence of a second active black hole in the galactic nucleus. These scenarios are tested by studying the relationship between the black hole mass, radio and optical luminosity, starburst history, and dynamic age of radio lobes in a sample of 29 X-shaped radio galaxies drawn from a list of 100 X-shaped radio source candidates identified from the FIRST survey. The same relationships are also studied in a control sample consisting of 36 radio-loud active nuclei with similar redshifts and optical and radio luminosities. The X-shaped objects are found to have statistically higher black hole masses and older starburst activity compared to the objects from the control sample. Implications of these findings are discussed for the black hole merger scenario and for the potential presence of active secondary black holes in post-merger galaxies.Comment: 11 pages, 8 figure
