Reproductive biology of three important small indigenous fish species mola (Amblypharyngodon mola), punti (Puntius sophore) and chela (Chela cachius) was studied for 12 months from January to December, 1999 in the Department of Fisheries Management, Bangladesh Agricultural University, Mymensingh. Gonadosomatic index (GSI) and ova diameter were analysed to determine their reproductive cycle. Thr...

The paper describes a new graphical model transformation language MOLA. The basic idea of MOLA is to merge traditional structured programming as a control structure with pattern-based transformation rules. The key language element is a graphical loop concept. The main goal of MOLA is to describe model transformations in a natural and easy readable way.

Efficiency of pattern matching for MOLA model transformation language is analyzed in the paper. A virtual machine and pattern matching procedure based on it is proposed, which takes into account the specific requirements for efficient pattern matching in MOLA. On the basis of a typical MDA example it is shown that the proposed solution is optimal and the conclusions are generalized to typical M...

Ocean sunfish, family Molidae, are enigmatic members of the epipelagic fauna of all tropical and temperate oceans. A study, begun in 1998, initially focused on the population genetics of Mola mola Linnaeus 1758 immediately indicated high levels of genetic divergence in the d-loop and cytochrome b mitochondrial genes. This preliminary effort was expanded to include Masturus lanceolatus Liénard 1...

Evidence is provided from stable isotope analysis that aggregations of small ocean sunfish Mola mola (total length <1 m) feed broadly within coastal food webs and their classification as obligate predators of gelatinous zooplankton requires revision.

Textual models in MDD typically are generated in their concrete syntax using a template based language. On the contrary, graphical models as a rule are generated in abstract syntax and then visualized, which is not very efficient for complicated languages. The paper discusses a case of template based generation of graphical models in a concrete syntax. We apply this approach to generation of pr...

Launched in 1996, Mars Global Surveyor (MGS) carries two types of mapping equipments: Mars Orbiter Laser Altimeter (MOLA) and Mar Orbiter Camera (MOC). MOLA collects accurate laser altimetry data over the Mars surface, while MOC acquires high resolution images. In the process of MOLA registration to MOC images, a certain systematic shift was reported in previous studies. This shift may possibly...
