Applied ecology - a new discipline to be developed to support aquaculture

Aquaculture or cultivation in water has become a common practice in almost all countries during recent times in the context of the limitations of harvest from the sea, or from freshwater bodies. Planned development by modern approaches in this sector will normally make it possible for organising aquaculture in the same way as agriculture and in many countries large scale cultivation of fish, edible oysters, mussels, Prawns, pearls, algae etc. are streamlined on industrial basis with proper management networks at production, marketing and at consumer levels

Equi-inclination Weissenberg intensities, scanned with an automatic densitometer. The structure, solved by direct methods, refined to R 0.0577 and R w 0.0649 for 1653 reflexions. The crystal structure is characterized by partial stacking of the chromophores, these are slightly non-planar

Role of reproductive bodies of algae as ultra microscopic food of larval and planktonic animals: a new finding in environmental science

Scientis ts believe that the bivalve larval reed on diatoms, detritus etc. When large scale spawning of these animals happens in the sea releasing million of larvae into the environment, no noticeable change is observed in the environment to show a boost of the feed material and it is also out of question that these millions of larvae are feeding on the dia toms of the sea which arc larger in size than the larval forms

Extra-curricular activities lead to healthy social skills among students in Malaysia

This paper discusses the benefit of extra-curricular activities in social skills among students in Malaysia. Student’s participation in extra- curricular activities can increase the social skills in terms of self-confidence, building relationship with the others, collaboration, etc. On the other hand, it can develop positive relationship outside the classroom environment and act as a catalyst for social skills. What's more, through additional curricular exercises, the creation of phenomenal human capital from the physical, passionate, otherworldly and scholarly perspective can be produced

A new and simple medium for phytoplankton culture

Results of the study using a simple medium with a higher concentration of phosphate, developed for isolating unicellular algae from Calicut region are presented in this paper. The new medium is found to be very simple for large scale culture of phytoplankton to develop larval feed in hatcheries. The medium is prepared by dissolving 350 mg of potassium di hydrogen phosphate and 900 mg of p'otassium nitrate in 125 ml di stilled water. One ml of this solution is added to a litre of boiled and filtered sea water. A stock solution of vitamin is made by dissolving 5 mg of B" and 95 mg of B, in 100 ml of distilled water and one ml of this solution is added to each litre of the nutrient mixed sea water. Chromulina sp. Pavlova sp. and Chlorella sp. are inoculated in 250 ml flasks containing the new medium and is simultaneously compared with another set of flasks containing Walne's medium under controlled conditions of light and at a temperature rangong from 28 to 30· C. After every twenty four hours, cell counts are made and it is observed that rapid multipli.:ation of cells occurs during the initial period itself and the exponential phase is continued from the sixth day upto 12th day with similar results in both the media. The results with dirt·erent concentrations of the nutrients in the new medium are also presented in the paper

System design for mussel culture

Mussel culture has been proved as one of the feasible progress for large-scale production of cheap protein food in many of the European countries having considerable potential for production to the tune of 600 tonnes/hectare as is reported from Spain

Multi crop farming system for farming marine animals for producing medicines

It is well known that all physicians who practised Ayurveda, Allopathy, Homoeopathy, Sidha, Unani, etc. were to depend on the phamlacopea systems of preparing medicinesfrom extracts of plants, minerals and elements in the crude forms as well as in the most sophisticated forms even from the pre-vedic periods dating back to 5000 to 7000 BC. Due to the recent advancements in the modern medicines, a new branch of science has been evolved for extraction of bio-active agents or substances from marine organisms and scientists developed many life saving medicine

CRYSTAL-STRUCTURE OF AN ORTHORHOMBIC FORM OF ADENOSINE-5'-MONOPHOSPHATE

Adenosine-Y-phosphate monohydrate was crystallized in the orthorhombic space group P212121, with a=22"997 (2), b=9.406 (1), c=6.599 (1)A,, Z=4. The structure was solved by direct methods and refined to a final Rw of 0.0639 for 1320 significant reflexions measured on an automatic diffractometer. The conformation of the molecule differs significantly from that previously reported for the monoclinic monohydrate [Kraut & Jensen, Acta Cryst. (1963), 16, 79-88]. The sugar conformation, for example, is here C(2)'-endo, and the glycosidic torsion angle has altered by almost 50 °

International trade policies and sustainability of nano-textiles

While a considerable part of developments in the field of industrial and technical textiles involves nanomaterials, there are increasing challenges faced across the world in their acceptability and sustainability. Their potential adverse impact has been documented in the scientific literature. European Commission and USEPA (United States Environmental Protection Agency) have already come up with regulations that govern these materials. In future, therefore, we can expect trade sanctions by these countries on exports of nano-textiles from countries like India. In this paper, we shall discuss the technical literature that points towards potential hazards of nano-textiles and the policy aspects currently in place. Further, we employ a widely used global economic (Computable General Equilibrium) model (GTAP – Global Trade Analysis Project) to evaluate the economic and business impact of such sanctions quantitatively, in a stochastic and comparative setting
