The Agathinai Components in Thirukkural
Based on the lives of the Sangam people, they created literature by distinguishing between love-genre literature and heroic-genre literature. The ambrosial Thirukkural, written by the world-famous Valluvar, is a universal holy verse and is a beacon to guide life and refresh literature that gives new meaning every time it is read. It is a book about life. Thirukkural is said to be suitable for all religions, all nations, and all times. In this book, Valluvar clearly explains the principles of the individual's life and how a mature man should be. Agam is a love feeling related to people's inner selves. Thinai is a discipline. So, love is an emotional discipline that can be called Agam. Kamathuppal (Love) is the third section of Thirukkural. This outlines the merits of the love-genre tradition. It has a literary flavour to it, and love reflects the lively character of chastity. It is Valluvar's 'Kamathuppal' that leads to the highest way of life, one-to-one. In this, the expression of love, commitment, and emotional values of the lovers are seen deliciously. Also, the characteristics, duties, and rights common to both sexes are explained. The agathinai components express love and pleasure. He has laid the foundation of love life in twenty-five chapters, divided into two parts: illicit courtship and chastity, which is the agam life. Ancient Tamils considered virtue as a way of life. If one lives a life of charity, one will get happiness. That pleasure is permanent. This article examines the agam components of domesticity as a virtue
Fisheries long term monitoring program : Preliminary Assessment of Juvenile Mangrove Jack around Weipa, May 2004
This report is a summary of the data collected in the Fisheries Long Term Monitoring Program freshwater fish surveys from 2000 to 2005.
Queenslandâs freshwater reaches contain a diverse array of freshwater fish fauna. Over 130 native species are recognised in north eastern Australia which is approximately half of the freshwater fish fauna of the Australian continent (Pusey et al. 2004).
The sustainability of freshwater fish is highly dependent on suitable riverine habitat as species diversity and populations are closely linked to habitat conditions. Exotic fish species including carp (Cyprinus carpio), tilapia (Tilapia, Oreochromis spp.) and mosquitofish (Gambusia spp.) may compete with, or prey on, the eggs and juveniles of native species.
The Department of Primary Industries and Fisheries (DPI&F) Long Term Monitoring Program (LTMP) has monitored the freshwater fish of 10 river systems in Queensland since 2000. The program uses electrofishing sampling techniques to collect annual information on populations of key recreational, commercial and exotic fish species. The program also collects ancillary information on water quality and habitat conditions that may help to correlate changes in fish community structure.
Species diversity in most rivers has remained fairly stable throughout the period of the study. Six exotic fish species have been encountered, with goldfish, European carp and tilapia being of major concern to state agencies.
The six years of sampling has been successful in obtaining a baseline dataset of the fish resources for the ten rivers monitored under the freshwater component of the LTMP
Memory, space and time: Researching children's lives
This article discusses the research approach in 'Pathways through Childhood', a small qualitative study drawing on memories of childhood. The research explores how wider social arrangements and social change influence children's everyday lives.The article discusses the way that the concepts of social memory, space and time have been drawn on to access and analyse children's experiences, arguing that attention to the temporal and spatial complexity of childhood reveals less visible yet formative influences and connections. Children's everyday engagements involve connections between past and present time, between children, families, communities and nations, and between different places. Children carve out space and time for themselves from these complex relations. © The Author(s) 2010
First evidence of industrial fly-ash in an Antarctic ice core
Spheroidal carbonaceous particles (SCPs) are a component of fly-ash, the particulate by-product of industrial high temperature combustion of fuel-oil and coal-series fuels. We provide the first evidence that these indelible markers of industrialisation have been deposited in Antarctic ice, thousands of kilometres from any potential source. The earliest observed particle was deposited in an ice layer from 1936 CE. While depositional fluxes are low, chemical analysis of individual SCPs indicates a coal combustion origin
The effect of feeding different sources and levels of selenium on growth performance and antioxidant status of broilers raised at two different temperatures
1.This study examined the effects of different dietary sources and levels of selenium (Se) on growth performance, hepatic and breast meat Se content, glutathione peroxidase (GSH-Px) activity and total antioxidant status (TAS) in blood, when fed to broilers from 14 to 35 d of age and reared at two different temperatures (20°C and 35 °C).
2. Five hundred and sixty male Ross 308 broilers were reared in a single floor pen and fed the same proprietary starter diet from 0 to 14 d age (229.9 g/kg CP and 12.67 MJ/kg ME, without Se supplementation).
3. The experiment started at 14 d age, and the birds randomly assigned to 112 raised-floor pens (0.36m2 area, 5 birds/pen). Each of the seven experimental diets were offered to birds in 16 pens within four rooms. Two rooms were at 20°C and two rooms were maintained at 35°C. The experimental diets were fed from 14 to 35 d age and contained 214.9 g/kg CP and 13.11 MJ/kg ME. The experimental diets were as follows; control diet containing background Se only (0.189 mg/kg; C); low level sodium selenite (0.376 mg/kg; LSS): high level sodium selenite (0.558 mg/kg; HSS); low level commercial B TraximŸ Se (0.244 mg/kg) (LBT); high level B TraximŸ Se (0.448 mg/kg; HBT); low level selenised yeast (0.290 mg/kg; LSY); high level selenised yeast (0.487 mg/kg; HSY).
4. Birds consumed more when raised at 20°C compared to birds reared at 35°C (Pâ€0.05). Birds fed lower Se level reared at 35°C had higher weight gain versus those fed higher Se level (P<0.05). Birds fed SY had the lowest feed intake, weight gain and FCE (P<0.05).
The greatest GSH-Px activity was observed in birds fed SS diets (P<0.001). There were interactions between diet x level for TAS, which were highest in birds fed LBT compared to birds fed HBT (P<0.05). Breast Se content was higher in birds fed HSY compared to LSY (P<0.001). The highest hepatic Se was seen in birds fed SY and lowest in C (P<0.001).
5. Birds fed BT diets showed similar levels of Se to those birds fed inorganic Se, and similar levels of GSH-Px to birds fed SY. Further comparative work with broilers fed BT and other Se supplemented diets may elucidate the findings from this report
Effect of feeding different sources of selenium on growth performance and antioxidant status of broilers
This study was conducted to determine the effect of different sources of selenium (Se) on breast and liver tissue deposition, apparent metabolisable energy (AME), growth performance and antioxidant status of broilers, measured as Se content in liver and breast tissues and glutathione peroxidase (GSH-Px) in blood, when used in 0â35 d broiler chicken diets.
2. A total of 200 male Ross 308 broilers were used in the feeding trial, which comprised two dietary phases, a starter from 0 to 21 d and finisher from 21 to 35 d of age. Four treatments with 10 replications each were used. A control diet (C) was formulated that was sufficient in protein and energy (230 and 215 g/kg of crude protein and 12.67 and 13.11 MJ/kg of metabolisable energy, respectively), for both phases, but contained background Se only from the feed ingredients. The first treatment diet (IS) was made from the C diet supplemented with 10.35 g/t inorganic source of elemental Se in both feed phases. The third treatment (SY) was the control diet supplemented with 136.36 g/t selenised yeast (Sacchromyces cerevisiae) in both feed phases. A fourth treatment (SS) was the C diet supplemented with 0.666 g/t sodium selenite an inorganic source of Se in both starter and finisher diets.
3. Birds fed the SY diet consumed less and weighed less than those fed IS or C (P < 0.05; 0â35 d of age), but there was no difference compared to birds fed SS diets. There were no differences in FCR or dietary AME between broilers fed different Se sources. All diets containing supplementary Se increased concentrations in the liver and breast muscle, and for GSH-Px levels in blood compared to birds fed the C diet (P < 0.001). Birds fed SY diets had greater Se levels in liver and breast tissues compared to birds fed any of the other diets (P < 0.001).
4. Diets supplemented with Se had variable effects on broiler growth performances and antioxidant status. Feeding Se from a yeast source has higher transfer into breast tissues. Feeding different sources and levels of Se to birds in a more challenging situation to induce oxidative stress may bring more conclusive results
Height and risk of death among men and women: aetiological implications of associations with cardiorespiratory disease and cancer mortality
OBJECTIVES: Height is inversely associated with cardiovascular disease mortality risk and has shown variable associations with cancer incidence and mortality. The interpretation of findings from previous studies has been constrained by data limitations. Associations between height and specific causes of death were investigated in a large general population cohort of men and women from the West of Scotland.
DESIGN: Prospective observational study.
SETTING: Renfrew and Paisley, in the West of Scotland.
SUBJECTS: 7052 men and 8354 women aged 45-64 were recruited into a study in Renfrew and Paisley, in the West of Scotland, between 1972 and 1976. Detailed assessments of cardiovascular disease risk factors, morbidity and socioeconomic circumstances were made at baseline.
MAIN OUTCOME MEASURES: Deaths during 20 years of follow up classified into specific causes.
RESULTS: Over the follow up period 3347 men and 2638 women died. Height is inversely associated with all cause, coronary heart disease, stroke, and respiratory disease mortality among men and women. Adjustment for socioeconomic position and cardiovascular risk factors had little influence on these associations. Height is strongly associated with forced expiratory volume in one second (FEV1) and adjustment for FEV1 considerably attenuated the association between height and cardiorespiratory mortality. Smoking related cancer mortality is not associated with height. The risk of deaths from cancer unrelated to smoking tended to increase with height, particularly for haematopoietic, colorectal and prostate cancers. Stomach cancer mortality was inversely associated with height. Adjustment for socioeconomic position had little influence on these associations.
CONCLUSION: Height serves partly as an indicator of socioeconomic circumstances and nutritional status in childhood and this may underlie the inverse associations between height and adulthood cardiorespiratory mortality. Much of the association between height and cardiorespiratory mortality was accounted for by lung function, which is also partly determined by exposures acting in childhood. The inverse association between height and stomach cancer mortality probably reflects Helicobacter pylori infection in childhood resulting inor being associated withshorter height. The positive associations between height and several cancers unrelated to smoking could reflect the influence of calorie intake during childhood on the risk of these cancers

This article was published in the International Journal of Social Research Methodology [© Taylor & Francis] and the definitive version is available at: http://dx.doi.org/10.1080/13645579.2012.649410This paper examines the use of visual methods during research encounters with children and young people when investigating their perspectives and feelings towards their home and school life. By revealing the advantages and constraints of three visual approaches, including Lego Duplo, rainbows and clouds and moodboards, the paper contributes to the range of techniques available when conducting research with children and young people. In conclusion, the paper highlights the depth of information which can be elicited from visual techniques as well as the oral data which can be obtained through the utilisation of visual methods
Feeding dihydroquercetin and vitamin E to broiler chickens reared at standard and high ambient temperatures
The use of natural antioxidants, in particular polyphenols such as dihydroquercetin (DHQ), in animal nutrition has recently increased in popularity. This may partly be due to the risk of increased incidences of heat stress associated with raising livestock in warmer ambient temperatures, facilitated by global warming, reducing antioxidant capacity. The current research demonstrates the effect of dietary DHQ, vitaminEand standard or high ambient temperatures on growth performance, energy and nutrient metabolism, gastrointestinal tract (GIT) development, jejunal villus morphometry and antioxidant status in broiler chickens. Each of the four experimental diets was fed to 16 pens of five birds, which were allocated to four rooms (four pens in each room). The temperature in two rooms was maintained at aconstant 35°C (high temperature; HT), and the temperature in the other two rooms was gradually reduced from 27°C at 7 dof age to 22°C at 20 dof age (standard temperature; ST). Rearing birds at HT reduced feed intake, weight gain, weight of small intestine, total GIT, liver, spleen, heart, villus height, villus surface area and lowered blood glutationperoxidase (GSH-Px). Dietary DHQ increased blood GSH-Px and total antioxidant status, increased heart weight and reduced caecal size. When fed separately, DHQ and vitamin E improved hepatic vitamin E concentration. Feeding vitamin Eincreased spleen and liver weights. When fed together, DHQ and vitamin Ereduced villus height, villus height to crypt depth ratio and villus surface area. Temperature and antioxidants did not affect energy and nutrient metabolism. There were no effects of dietary antioxidants on growth performance of broiler chickens and there were no mortalities. At present, it is unclear if feeding antioxidants (in particular DHQ) at different levels, using different dietary formulations, and rearing birds under arange of environmental conditions may be effective at enhancing production performance and bird health in hot ambient climates
The ANTARES Optical Beacon System
ANTARES is a neutrino telescope being deployed in the Mediterranean Sea. It
consists of a three dimensional array of photomultiplier tubes that can detect
the Cherenkov light induced by charged particles produced in the interactions
of neutrinos with the surrounding medium. High angular resolution can be
achieved, in particular when a muon is produced, provided that the Cherenkov
photons are detected with sufficient timing precision. Considerations of the
intrinsic time uncertainties stemming from the transit time spread in the
photomultiplier tubes and the mechanism of transmission of light in sea water
lead to the conclusion that a relative time accuracy of the order of 0.5 ns is
desirable. Accordingly, different time calibration systems have been developed
for the ANTARES telescope. In this article, a system based on Optical Beacons,
a set of external and well-controlled pulsed light sources located throughout
the detector, is described. This calibration system takes into account the
optical properties of sea water, which is used as the detection volume of the
ANTARES telescope. The design, tests, construction and first results of the two
types of beacons, LED and laser-based, are presented.Comment: 21 pages, 18 figures, submitted to Nucl. Instr. and Meth. Phys. Res.
