A new RP-HPLC method for the determination of Tenofovir Disoproxil Fumarate in pure form and pharmaceutical formulation
The present study aimed to develop the new method for the estimation and validation of tenofovir in pure form and in pharmaceutical dosage form by RP-HPLC. The chromatogram of tenofovir was developed through column (Hyper ODS2 C18), UV detection at 260 nm at a flow rate of 1.2 ml/min with Methanol and Phosphate buffer (90:10) as mobile phase. The method was validated by various validation parameters such as accuracy, precision, linearity, specificity as per the ICH guidelines. A linearity range and retention time of Tenofovir were found to be 20-110 ┬╡g/ml and 2.1тАЙmin respectively. The % RSD of the Tenofovir was found to be 0.7. The % recovery was obtained as 99.7% for standard and 96.32% for tablets. This method was simple, accurate, precise and sensitive. Hence, the developed method was employed for the routine analysis of Tenofovir in the pharmaceutical dosage form

Cephalopod fishery off Thoothukudi coast, Tamil Nadu
In Thoothukudi district of Tamil Nadu, cephalopod resources are principally exploited by single day trawlers followed by hook and line. During 2012-18, nearly 54% of cephalopods landed were caught by mechanised trawl net; 32% by outboard crafts operating hook and line, 8% by gill net and rest by other gears. From 2012-18, the cephalopod landing showed a fluctuating trend and major cephalopod species landed by trawl net were Sepia pharaonis, S. prabahari, Sepioteuthis lessoniana, Uroteuthis (P) singhalensis and U. (P) duvaucelii. In hook and line, S. pharaonis was the dominant species followed by S. lessoniana and Octopus cyanea

Banana Fibre-Reinforcement of a Soil Stabilized with Sodium Silicate
Many unsuitable soils for construction purposes can be made suitable by using unconventional soil stabilizers. This study investigates the effects of banana fibre-reinforcement of a soil stabilized with sodium silicate on the geotechnical properties of the composite. It involved the application of 1% sodium silicate with varying proportion (0.1, 0.2,0.3, 0.4 and 0.5%) of banana fibre to a gravelly sand. Index properties, unconfined compression, direct shear, splittensile and California bearing ratio (CBR) tests were determined for the stabilized soil and the reinforced soil samples. The results show that the plasticity index, unconfined compressive strength (UCS), shear strength, splittensile
strength and CBR of the specimens stabilized with sodium silicate increased with increasing percentage of
banana fibre content. The application of 0.5% banana fibre strengthened the soil - the UCS increased by 445%,
shear strength by 80%, split tensile strength by 194% and the soaked CBR increased by 1083%. The banana fibrere inforcement of the sodium silicate stabilized sandy soils made the stabilized soil become suitable for road pavement application as sub-base material
Minimum Legal Size proposed for commercially exploited marine finfish and shellfish resources of Tamil Nadu
Marine fisheries in Tamil Nadu have undergone
tremendous change in terms of fishing pattern, fishing
method, extension of fishing grounds, composition
of fish catch and consequent increase in the total
fish catch in recent years. The recent demand from
industries involved in fish meal and fish oil encourages
targeted fishing for by-catch resulting in heavy landing
of low value by-catch in certain places along Tamil
Nadu coast. These by-catch are often dominated by
juveniles of many commercially important marine
finfishes and shell fishes. So it warrants some caution
and intervention. One of the methods to discourage
the indiscriminate exploitation of juveniles is to
impose a Minimum Legal Size (MLS) which is the size
at which a particular species can be legally retained
if caught. The advantage of a MLS is that it aids in
the control of two major problems in the fisheries
management, growth overfishing and recruitment
overfishing either by increasing the minimum size of
harvest or by increasing or maintaining the size of
the spawning stock. The most common method of
increasing the reproductive output through the use
of size limits is to set the minimum size at which the
females become sexually mature. As the individuals
of a species do not attain sexual maturity at the same
size, it can be a size at which higher proportions are
mature
