Present status of exploitation of fish and shellfish resources: Prawns
The Prawn fishery of the west coast of India is reviewed with particular reference to monsoon season and related
management problems based on observations at Cochin, Calicut, Mangalore and Bombay. With an estimated average
annual production of about 25,000 tonnes for the period 1984-88, the monsoon season contributes only 15% to the total
prawn landings of this coast. While shrimp trawling remains almost completely suspended in most of the centres during
this period, it is very active at Cochin and Sakthikulangara in Kerala Coast and moderately active in Bombay Coast
Ultrassonografia testicular em bovinos jovens da raça Nelore criados em sistema extensivo
Este estudo visou avaliar o padrão ultrassonográfico do parênquima testicular de touros jovens da raça Nelore, desde a fase peripuberal até a puberdade, estabelecer padrões fisiológicos e também verificar se existe diferença de ecogenicidade entre animais púberes e pré-púberes na mesma idade. Foram realizados exames ecográficos dos testículos de 19 bovinos aos 10, 12, 14, 16 e 18 meses de idade. O padrão ultrassonográfico do parênquima testicular mostrou-se homogêneo e com ecogenicidade moderada. A ecogenicidade testicular aumentou em proporção direta com a idade dos animais. Não houve diferença significativa entre a ecogenicidade testicular de animais púberes e pré-púberes na mesma idade
Baseline factors associated with early and late death in intracerebral haemorrhage survivors
Background and purpose:
The aim of this study was to determine whether early and late death are associated with different baseline factors in intracerebral haemorrhage (ICH) survivors.
Methods:
This was a secondary analysis of the multicentre prospective observational CROMIS‐2 ICH study. Death was defined as ‘early’ if occurring within 6 months of study entry and ‘late’ if occurring after this time point.
Results:
In our cohort (n = 1094), there were 306 deaths (per 100 patient‐years: absolute event rate, 11.7; 95% confidence intervals, 10.5–13.1); 156 were ‘early’ and 150 ‘late’. In multivariable analyses, early death was independently associated with age [per year increase; hazard ratio (HR), 1.05, P = 0.003], history of hypertension (HR, 1.89, P = 0.038), pre‐event modified Rankin scale score (per point increase; HR, 1.41, P < 0.0001), admission National Institutes of Health Stroke Scale score (per point increase; HR, 1.11, P < 0.0001) and haemorrhage volume >60 mL (HR, 4.08, P < 0.0001). Late death showed independent associations with age (per year increase; HR, 1.04, P = 0.003), pre‐event modified Rankin scale score (per point increase; HR, 1.42, P = 0.001), prior anticoagulant use (HR, 2.13, P = 0.028) and the presence of intraventricular extension (HR, 1.73, P = 0.033) in multivariable analyses. In further analyses where time was treated as continuous (rather than dichotomized), the HR of previous cerebral ischaemic events increased with time, whereas HRs for Glasgow Coma Scale score, National Institutes of Health Stroke Scale score and ICH volume decreased over time.
Conclusions:
We provide new evidence that not all baseline factors associated with early mortality after ICH are associated with mortality after 6 months and that the effects of baseline variables change over time. Our findings could help design better prognostic scores for later death after ICH

Concurrent white noise and acute hypobaric hypoxia: Effect on aviation cognitive performance
Introduction:
Optimal cognitive performance is the essence of effective execution of a flying mission. Effects of two commonly encountered aviation stressors, hypoxia and noise, on performance have been studied. However, studies on effects of concurrent dual effects of both these stressors on key cognitive parameters are sparse; hence, the objective was to examine these effects.
Material and Methods:
Cognitive performances were assessed among 30 healthy volunteers (28 males and 2 females) sequentially in four different conditions – baseline (without stressors), 85 dB(A) noise, 14,000 ft altitude, and concurrent exposure to 85 dB(A) noise at 14,000 ft altitude. White noise was simulated through software, altitude in the hypobaric chamber and cognitive performance was assessed with tests from Psychology Experiment Building Language (PEBL) test battery. Data were analyzed using descriptive statistics and repeated measures ANOVA.
Results:
The study revealed statistically significant direct detrimental effect of altitude and noise on implicit reaction time independently as well as concurrently. However, there was insignificant interaction effect between the dual stressors on implicit reaction time. There were no statistically significant effects of dual stressors on implicit correctness, visuospatial working memory, and selective attention. Although statistically not significant, noise enhanced the performance level in the form of increased Corsi block memory span and Corsi block total score.
Conclusion:
No significant effect of the dual stressors was observed on most of the cognitive parameters. However, implicit reaction time, a measure of pilot’s risk-taking behavior, was found to be significantly affected by the dual stressors. Further research with a larger sample of aircrew population who differ in age, experience, and other potentially influencing factors is recommended.
