Hence they have a direct effect on recreational activities like fishing‚ bait collection‚ diver collection etc. The present study has used secondary data from all ready conducted researches on the subject matter and has addressed a lot of questions like the effect of MPAs on recreational activities with focus on temperate waters‚ the advantages and disadvantages of these MPAs on recreational

Controversial Role of Marine Protected Areas in Fishers Management Introduction Marine protected areas(MPAs)‚ what Kelleher and Kenchington from IUCN mentioned in 1992 has become the most commonly used definition of MPAs‚ “Any area of inter-tidal or sub-tidal terrain‚ together with its overlying water and associated flora‚ fauna‚ historical‚ or cultural features‚ which has been reserved by law or other effective means to protect part or all of the enclosed environment.” (Kelleher and Kenchington

tensile strength steel series from TS780 MPa to 1 470 MPa with excellent formability and weldability which reduces weight and increases safety in collision when they are applied to the reinforcement parts around a cabin. Those ultra-high tensile strength steels are developed by applying JFE Steel’s own technology‚ continuous annealing line water-quenching facilities which greatly contribute to reduce alloy elements in the steel. Especially‚ the TS1180 MPa steel which is expected to expand in

In the U.S.‚ MPAs span a range of habitats including the open ocean‚ coastal areas‚ inter-tidal zones and estuaries; they also vary in purpose‚ management approaches‚ legal authorities‚ agencies‚ and limitation of human uses. The MPAs are set up for conserving the marine biodiversity and protecting‚ associated with reducing destruction‚ and the reduction in distribution

The Metabolic fate of ethyl O-[N-(p-carboxyphenyl)-carbamoyl] mycophenolate (CAM)‚ a new anticancer agent‚ in experimental animals. The pharmacokinetics of a new anti-tumor agent i.e. ethyl o- [N-(p- carboxy phenyl)- carbamoyl] Mycophenolate (CAM) was studied in mice by using 14 c-labeled CAM and also metabolic differences were studied in species like rats‚ mice‚ rabbits‚ guinea pigs & dogs.

The heating pressure of 30‚ 40‚ 50 MPa‚ heating time of 3‚ 4‚ 5 sec‚ upset pressure of 60‚ 70‚ 80 MPa‚ upset time of 2‚ 3‚ 4 sec were used to weld the joints. L9 orthogonal design concept was used. Results revealed that no intermetallic phases were formed. By increasing the heat input the tensile strength of the joint
