    Description: The widespread use of microalgae in various fields of human activity including fishery generated a need of highly productive technologies of industrial production of microalgae biomass. In present paper, extreme productivity values of microalgae culturing system were assessed around neighborhoods of the Isfahan City in theory. It will amount to 37.90 g of dry weight (g. d. w.) per 1 m^2 of the illuminated reactor surface under condition that efficiency factor of photobiosynthesis equals to 5%. When photobiosynthetic efficiency is 15%, maximum values of productivity will be 113.71 g. d. w. per 1 m^2. Productivity of microalgae culturing system for its various orientations relative to the Sun at different photobiosynthetic efficiency was calculated on basis of simple model understandings regarding average caloric content of 1 g.d.w. of microalgae and the daily distribution of solar radiation which arrives at the surface of the Earth. If it is drown a curve of the third order (spline) through the points corresponding to days of the vernal (21 March) and autumnal (21 September) equinoxes and a summer solstice (22 June), the extreme (ideal) value of the yield will be 18.5 kg of dry biomass per square meter of illuminated surface (at photobiosynthetic efficiency of 0.15).

    Description: Using SWOT analysis with traditional matrix and quantitative matrix methods, the strategies to benefit from strengths and opportunities to vanishing weaknesses and decrease of threats for strategic management of aquaculture in Iranian Northern provinces was surveyed. Utilizing researches held in fisheries research centers and existence of aquaculture experts in vicinity, activation of veterinary organization in production and post production, and entering new brood stocks with desirable growth are the main strategies for developing rainbow trout and Chinese carps culture in Iranian Northern provinces. In sturgeon fishes culture, independence of farms from fingerlings produced by governmental complex and diversification the cultured fishes using new species and hybrids can develop this part of aquaculture. Avoiding illegal fishing in sea and rivers, preserving the population of Caspian Sea fishes, entering new fish species which their resources are decreased extremely to breeding and fingerling production cycle, and using pike perch and bream while they migrate to Anzali Lagoon from Caspian Sea, instead of freshwater brood stocks will cause the output of sea enhancement and sea ranching activities to increase, and fisheries return coefficient of these fishes will rise. Using quantitative matrix and scoring method, it was defined that aquaculture in Iranian Northern provinces are extremely approved and acceptable and the score of strengths is more than weaknesses and opportunities more than threats. By using strategic management, these activities can be more developed.

    Description: Bycatch from trawlers forms a signifi cant quantity of the total marine fi sh landings along the northwest coast of India, particularly in the state of Gujarat, which contributes about 23 percent of the total marine fi sh landings in the country. This paper discusses the composition of this bycatch, its signifi cance in terms of nutritional value, its present utilization pattern and the scope for improvement.

    Notes: Das in seiner Struktur als 11-Hydroxy-1.2-methylendioxy-aporphin (16) aufgeklärte2) Alkaloid Pukatein wurde synthetisiert. Aus dem Amin 9 und 2-Nitro-3-benzyloxy-phenyl-essigsäure (8) (Weg A) bzw. 2-Nitro-3-benzyloxy-ω-diazo-acetophenon (7) (Weg B) wurde das Amid 10 hergestellt. Isochinolinringschluß nach Bischler-Napieralski und Pschorr-Ringschluß führten zum (±)-11-Benzyloxy-1.2-methylendioxy-aporphin (15), dessen Hydrogenolyse 16 ergab.

    Description: Measurements of the altitude, latitude, angle, and energy distributions of 5-80-MeV neutrons at 29 deg S geomagnetic latitude and 8.5-GV cutoff, obtained with the University of California neutron double-scatter telescope on a flight from Alice Springs, Australia, on November 10, 1981, are reported. The data are presented in extensive tables and graphs and characterized in detail. The altitude distribution of upward-moving and downward moving neutrons is found to peak at 100 g/sq cm (as reported for 41 deg N geomagnetic latitude by Preszler et al., 1974), while the angular distributions exhibit dips at 60 and 130 deg and the energy distribution has a flat region at about 20 MeV. The escape current of 0.059 + or - 0.008 neutrons/sq cm sec is consistent with theoretical models for the injection of energetic protons into the earth radiation belt (Merker, 1972 and 1975).

    Description: Theoretical calculations are presented that explain the balloon observations by O'Neill et al. (1987) of a strong north-south anisotropy of atmospheric gamma rays over the Southern Hemisphere, and to predict the north-south ratios. It is shown that the gamma rays that originate at the longest distances from the telescopes give the largest north-south ratios. Comparisons are made of the experimental north-south ratios measured on balloons launched from Alice Springs, Australia, and from Palestine, Texas, U.S., and predictions are made for ratios at other geomagnetic latitudes and longitudes. It is pointed out that observers who measure backgrounds for celestial sources may be misled unless they correct for the north-south effect.
