Some observations on washout of brown trout (Salmo trutta L.) eggs in Teesdale streams

Brown trout (Salmo trutta) in Teesdale lay their eggs in the streambed gravels in the Autumn, here the eggs slowly develop to emerge as young fry in the Spring. Whilst the eggs are in the gravel they are vulnerable to displacement by high water velocities. Eggs removed in this way are not thought to remain viable since they are very susceptible to death through physical shock - especially in the earlier stages of development. Streams in Teesdale are known to be amongst the most flashy in England and thus are good sites in which to study egg washout. Three field sites were used for the study of egg washout in Teesdale - Great Eggleshope, Thorsgill and Carl becks. This report describes preliminary studies of a varied nature into this subject from which an attempt is made to assess the importance of egg washout to the survival of brown trout in Teesdale

Oyster Coverage: Chiastic News As a Reflection of Local Expertise and Economic Concerns

The media, it is argued, are agents of legitimation - for themselves as well as others. Issues and social actors become recognized as important when they appear within the limelight of the news, and reporters are relied upon to correctly choose among the myriads of issues and actors vying for their attention. What happens, though, when an economically important cultural icon becomes a health threat? This is the situation facing news organizations in Southern Louisiana where oysters are both loved and loathed as food. We study newspaper presentations of oysters in Southern Louisiana over a ten-year period to investigate the ways in which this issue was approached. In many of the instances when negative articles appeared, positive statements could be found in the same issue of the newspaper, creating what we refer to as chiastic -- defined as two parallel lines moving in opposite directions -- media presentations. The presence of this type of news reporting is discussed in terms of the economic and cultural importance of the oyster, the economics of newspapers, and the stance of news organizations as cultural authorities.Chiastic, Culture, Economics, News, Oyster

Tunneling calculations for GaAs-Al(x)Ga(1-x) as graded band-gap sawtooth superlattices

Quantum mechanical tunneling calculations for sawtooth (linearly graded band-gap) and step-barrier AlGaAs superlattices were performed by means of a transfer matrix method, within the effective mass approximation. The transmission coefficient and tunneling current versus applied voltage were computed for several representative structures. Particular consideration was given to effective mass variations. The tunneling properties of step and sawtooth superlattices show some qualitative similarities. Both structures exhibit resonant tunneling, however, because they deform differently under applied fields, the J-V curves differ

Testing positive for human papillomavirus in routine cervical screening: examination of psychosocial impact

Objective To examine the psychosocial impact of testing positive for high risk human papillomavirus (HPV) among women attending primary cervical screening.Design Cross sectional survey.Measures were taken at baseline and one week after the receipt of HPV and cytology screening results.Setting Well women's clinic in London, UK.Population or Sample Four hundred and twenty-eight women aged 20-64 years.Methods Postal questionnaire survey.Main outcome measures Psychosocial and psychosexual outcomes were anxiety, distress and feelings about current, past and future sexual relationships.Results Women with normal cytology who tested positive for HPV (HPVdivided by) were significantly more anxious and distressed than women who were negative (HPV-) using both a state anxiety measure [F(1,267)=29, P<0.0001] and a screening specific measure of psychological distress [F(1,267)=69, P<0.0001]. Women with an abnormal or unsatisfactory smear result, who tested HPV,. were significantly more distressed than HPV- women with the same smear result [F(1,267)=8.8, P=0.002], but there was no significant difference in state anxiety. Irrespective of cytology result, HPV women reported feeling significantly worse about their sexual relationships. Approximately one-third of women who tested positive reported feeling worse about past and future sexual relationships compared with less than 2% of HPV- women.Conclusion The findings suggest that testing positive for HPV may have an adverse psychosocial impact, with increased anxiety., distress and concern about sexual relationships. Psychosocial outcomes of HPV testing need further investigation and must be considered alongside clinical and economic decisions to include HPV testing in routine cervical screening
