9-CHLOROACRIDINE

C~3HsNC1, orthorhombic, P212~2 ~, a = 6.850 (3), b = 11.662 (5), c = 12.705 (5) A, O m = 1.40 (1), D c = 1.393 g cm -3 for Z = 4. 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

NUCLEIC-ACID BINDING DRUGS .2. PROFLAVINE FREE BASE

C13HIIN3.H20 , orthorhombic, Cmc21, a= 14.493 (8), b= 14.675 (8), c= 5.772 (5) A, Din= 1.29 (1), De= 1.298 g cm -3 for Z=4. Equi-inclination Weissenberg intensities, scanned with an automatic densitometer. The structure, solved by direct methods, was refined to R 0.0928 and Rw 0.0910 for 418 reflexions. The ring system is slightly non-planar, and the crystal structure is characterized by a lack of interplanar stacking

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 °

CRYSTAL AND MOLECULAR-STRUCTURE OF 2',3',5'-TRI-O-ACETYL-6-O-(MESITYLENESULPHONYL)GUANOSINE

The structure of a 6-O-mesitylenesulphonyl derivative of 2',3',5'-tri-O-acetylguanosine, C 24 H 29 N50 10 S, has been determined by X-ray diffraction. Crystals are monoclinic, a = 26.370 (4), b = 8.200 (2), c = 17.991 (3) A, fl = 132.77 (4) o. The solution of the structure in space group C2 was not straightforward and is described in detail. Refinement converged at R = 0.110 for 1102 observed reflections. The guanine base displays some deviations from its usual geometry due to the loss of C(6)-O(6) double-bond character. The ribose sugar is C(2')-endo puckered

The clam resources

Che estuaries and backwaters along the coasts of India have immense clam resources which have been traditionally exploited by the coastal people. The clams form the basis of subsistence for the fishermen during seasons when sea fishing is at a low ebb and clam fishing is a regular activity in many coastal regions of Maharashtra, Goa, Karnataka and Kerala on the west coast. Along the east coast, clam fishing is restricted to a few centres such as the Kakinada Bay although, here and there, they are collected for culinary purposes elsewhere. This is an activity where, besides men and women, children participate. Clam marketing is highly localised in centres of collection. Apart from introduction of improved clam-scooping devices, the fishing method of hand-picking has largely remained unchanged over the years

Some observations on light fishing off Thiruvananthapuram coast

The artisanal fisheries of the Thiruvananthapuram coast axe of considerable importance in the fisheries of Kerala State due to their significant contributions to the catch of resources like tunas, anchovies, ribbonfish, caranglds, perches and cephalopods

Review on cephalopod resources, biology and stock assessment in Indian seas

Cephalopods are fished from the seas around India from very early times and at present contribute one of the most important exploited marine fishery resources oj the country (between 4 and 5% of the all India production). The production, which remained at very low level up to the early seventies, has shown a remarkable increase crossing the 1,00,000 tonne mark in 1994. The taxonomy, biology and stock assessment of the various exploited species have been studied since the early seventies by the CMFRI. Studies indicate that uplo 1994 tlie exploitation has remained within rational limits in almost all maritime states. The recent rapid increase in production warrants close monitoring of this short-lived resource from the viewpoint of Judicious management

Maintenance Optimization in Process Plant Using Failure mode effect analysis

Experimental investigations are conducted to assess the influence of various equipment in terms of MTBF(Mean time between failures) and MTTR(Mean Time To Repair) in this study. Analysis of these data has helped to find out the critical components in coil and mill Plant at Anjar, Kutch, India. The goal of this work is to analyze the maintenance data and recommend optimized maintenance plan. The genetic algorithm is proposed as a heuristic search method for maintenance optimization in Plate and coil mill plant unit. Genetic algorithm searches for the best solution for the efficiency enhancement of the plant. This paper presents the influence of genetic algorithm in maintenance optimization in Plate and coil mill plant. Failure mode effect analysis is the used methodology in proposed work which is a fundamental piece of the specialized plan of support to enhance framework quality and hence lessens costs related with upkeep that is utilized as a part of a wide range industry
