An instance of hermaphroditism in the Indian mackerel Rastrelliger canagurta 'Cuvier'

While instances of hermaphroditism are known to occur in the European mackerel (Scomber scombrus L. no such cases are on record fcr the Indinn mackerel, Rastrelliger canagurta. It is interesting to report, therefore, the occurrence of a single hermaphrodite specimen of R. canagurta in a sample taken from the fish market at Karwar and reported to have been caught at Majali, seven miles north of 'Karwar on 25th March 1958

Genetic diversity analysis of pearl millet (Pennisetum glauccum [L.] R. Br.) accessions using molecular markers

Random amplified polymorphic DNA (RAPD) analysis was applied to pearl millet genotypes in order to assess the degree of polymorphisms within and among genotypes and to investigate if this approachwas suitable for genetic studies of pearl millet. 20 genotypes were evaluated using 30 different 10-mer primers of arbitrary sequence. Most of the primers did not reveal any polymorphism; however 12primers revealed scorable polymorphism between genotypes of pearl millet and these can be further evaluated for use in genetic mapping. Pair-wise comparisons of unique and shared polymorphic amplification products were generated by Jaccard’s similarity co-efficient. These similarity co-efficientswere employed to construct a dendrogram showing phylogenetic relationships using unweighted paired group method with arithmetic averages (UPGMA). The UPGMA analysis indicated a higher similaritybetween genotype PT 2835/1 and PT 5552 and lowest similarity index was observed between PT 5554 and PT 2835/1. Analysis of RAPD data appears to be helpful in determining the genetic relationship among 20 pearl millet genotypes. The associations among the 20 genotypes were also examined with Principle components analysis (PCA) from Jaccard’s similarity co-efficient and it is more informative to analyze the extreme genotypes

Night sky at the Indian Astronomical Observatory during 2000-2008

We present an analysis of the optical night sky brightness and extinction coefficient measurements in UBVRI at the Indian Astronomical Observatory (IAO), Hanle, during the period 2003-2008. They are obtained from an analysis of CCD images acquired at the 2 m Himalayan Chandra Telescope at IAO. Night sky brightness was estimated using 210 HFOSC images obtained on 47 nights and covering the declining phase of solar activity cycle-23. The zenith corrected values of the moonless night sky brightness in mag/square arcsecs are 22.14(U), 22.42(B), 21.28(V), 20.54(R) and 18.86(I) band. This shows that IAO is a dark site for optical observations. No clear dependency of sky brightness with solar activity is found. Extinction values at IAO are derived from an analysis of 1325 images over 58 nights. They are found to be 0.36 in U-band, 0.21 in B-band, 0.12 in V-band, 0.09 in R-band and 0.05 in I-band. On average, extinction during the summer months is slightly larger than that during the winter months. No clear evidence for a correlation between extinction in all bands and the average night time wind speed is found. Also presented here is the low resolution moonless optical night sky spectrum for IAO covering the wavelength range 3000-9300 \AA. Hanle region thus has the required characteristics of a good astronomical site in terms of night sky brightness and extinction, and could be a natural candidate site for any future large aperture Indian optical-infrared telescope(s).Comment: 18 pages, 7 figures, uses basi.cls, accepted for publication in Bulletin of the Astronomical Society of Indi

Examining fast-food consumption behaviour of students in Manipal University, India

Eating out in India has evolved from an occasion-driven activity to an everyday activity and fast-food has become a significant symbol for the modern culture as it tends to satisfy customers in a relatively short time. The fast food industry in India has evolved with the changing lifestyles of the young Indian population. The sheer variety of gastronomic preferences across the regions, hereditary or acquired, has brought about different consumption patterns across the country. In this paper, efforts are taken to learn the fast food consumption behavior of students’ in Manipal University campus which has nearly 25,000 students from different parts of India and from across the world. It also has over one hundred fast food outlets with varied themes to tantalize the taste buds of its diverse clientele. Survey analysis shows that the majority of students prefer burgers, pizzas and rolls, while male students prefer fizzy drinks, fresh juice and milk shakes as beverages. Female students tend to prefer fresh juice, coffee and mock-tails, especially on weekends, while with their friends. It is important to note that both male and female have given similar priority for factors deemed to be important in directing them to a particular item, such as quality of the product, timeliness of service and a reasonable price, while some differences exist in aspects related to cleanliness and hygiene, and brand image as per the T-test for equality of means

Introducing criteria and indicators for monitoring and auditing forest management in the Brazilian Amazon.

O desenvolvimento de mecanismos de controle internos e externos das atividades das indústrias madeireiras contribuem essencialmente para a implementação efetiva de práticas de bom manejo. Sob o princípio de que a sustentabilidade é a chave mestre para um bom manejo florestal, os critérios e indicadores (C&I) constituem uma ferramenta ideal para avaliar a sustentabilidade através do desenvolvimento de sistemas simples e viáveis de monitoramento e auditoria. O desenvolvimento de C&I para uso em monitoramento e para auditoria foi um dos focos principais de uma pesquisa de um projeto demonstrativo na Amazônia Brasileira coordenado pela EMBRAPA Amazônia Oriental e pelo CIFOR. Quatro pontos foram reportados: (1) Definição de uma lista preliminar de C&I adaptados regionalmente em uma oficina internacional com peritos na área de manejo florestal; (2) Avaliação e refinamento desta lista por quatro grupos interdisciplinares (pesquisadores, agentes governamentais, grupo operacional e atores locais); (3) Desenvolvimento de protótipos de monitoramento e auditoria (incluindo recomendações de manejo) baseado na avaliação dos resultados, e (4) Validação dos instrumentos definidos através da aplicação supervisionada em diferentes empresas florestais e entidades de auditoria. Como parte deste processo, o teste de campo de um conjunto preliminar de C&I realizado pelos diferentes grupos de atores, confirmou a maior praticidade de C&I baseado no controle de atividades, assim como o potencial e a necessidade de métodos participativos no desenvolvimento do processo. Além disso, as análises confirmam que os trabalhos prático com sistemas de C&I terão que focalizar mais a níveis de verificadores. Os verificadores sociais e ecológicos precisam ser mais específicos e terão que ser desenvolvidos métodos mais práticos para sua avaliação. Para assegurar uma interpretação efetiva dos resultados do monitoramento e auditoria recomenda-se estrutura r os C&I em quatro categorias: existência e qualidade da documentação, implementação eficiente dos planos, impactos das atividades empresariais e condições externas para a sustentabilidade

Improved mechanical and microstructural performance of high-density polyethylene-chitosan-hydroxyapatite composites as potential bone implant materials

High-density polyethylene (HDPE)-chitosan-hydroxyapatite hybrid composite series with varying concentration of hydroxyapatite were prepared and compared with its corresponding HDPE-chitosan binary composite. The microstructural and mechanical characterizations of the prepared composites were studied. A 12% increase for the composite system with 8 wt% hydroxyapatite (HA4) has been noted when compared with its corresponding binary system and has been optimized for further applications. The structural characterization and miscibility of the components in the composite system were studied by using Fourier transform infrared spectroscopy and X-ray diffractometry. Positron annihilation lifetime spectroscopy studies showed that the free holes are formed in the range of similar to 115.8 angstrom(3). Contact angle studies and sorption studies were further correlated with the biocompatibility analysis to study cell adhesion and protein absorption on the surface of the composites. MC3T3 E1 cell lines showed good cell proliferation on the optimized systems. The presence of micropores along with chitosan and hydroxyapatite promoted cell growth in the prepared composites. The current research study presents the development of an improved hybrid biocomposite material that has potential in biomedical implants. (C) 2022 Elsevier Ltd. All rights reserved
