    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.

    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 / Table of Contents: Absolute Configuration of I+)- and {-)-2-Amino-tetralin and of the four Isomeric 2-Amino-tetralols- ( I )Maintaining its configuration, L-(+)-aspartic acid is converted to (-)-(2S)-2-amino-tetralin, and its absolute configuration thus determined. The hydrogenolysis of three of the four isomeric 2-amino-tetralols-(1) 7a, 7b, and 7c with Pd led to the optically pure (+)- and (-)-2-amino-tetralins (6a and 6b), which allows one to make a definite statement regarding the steric structure of the levo- and dextrorotatory cis- and trans-2-amino-tetralols-(1). It could be shown that, contrary to previous assumptions, based on CD-spectra, (+)-(1S, 2R)-2-amino-tetralol-(1) (7c) does not have the same absolute configuration as L-(-)-ephedrine, with the absolute configuration (1R, 2S). Therefore for arylaminoethanols, it is not possible to correlate the open-chained and cyclic compounds to one another by means of the CD-spectraalone.
    Notes: 1.-(+)-Asparaginsäure wird unter Erhaltung ihrer Konfiguration in (-)-(2S)-2-Amino-tetralin umgewandelt und damit dessen absolute Konfiguration festgelegt. Durch Hydrogenolyse von drei der vier isomeren 2-Amino-tetralole-(1) 7a, 7b, 7c mit Palladium werden (+)- und (-)-2-Amino-tetralin (6a und 6b) optisch rein erhalten, was Rückschlüsse auf die räumliche Struktur der links- und rechtsdrehenden cis- und trans-2-Amino-tetralole-(1) zuläßt. Es zeigt sich, daß entgegen früheren Annahmen, denen circulardichroitische Messungen zu Grunde lagen, (+)-(1S, 2R)-2-Amino-tetralol-(1) (7c) nicht dieselbe absolute Konfiguration besitzt wie L-(-)-Ephedrin mit der absoluten Konfiguration (1R, 2S). Es ist daher bei Arylaminoäthanolen nicht möglich, ohne weiteres durch CD-Spektren offenkettige und cyclische Verbindungen einander zuzuordnen.

    Notes: Investigations on the Thermal Decomposition of n-Dodecylcyclopentane in the Gas PhaseIn the thermal decomposition of n-dodecylcyclopentane at 670 and 750°C in a laboratory tubular reactor mixtures of hydrogen and 57 and 113 hydrocarbons respectively are formed. The mixtures have been analyzed and identified by capillary gas chromatography and by mass spectrometry. The distribution of the reaction products is used for mechanistic discussions.

    Notes: Thermal Reaction of Mono-n-alkyl-benzenesThe pyrolysis of ethyl-(1), n-propyl-(2), n-hexyl-(3) and n-octylbenzene (4) has been studied under conditions of steam cracking (600 to 800°C) in a laboratory scale tubular reactor. The overall activation energies determined for (1) to (4) were found to be nearly identical (221 to 227 kJ · mol-1) obviously caused by similar initial steps. The main liquid product observed was styren accompanied by ω-phenyl-1-alkenes and α-olefins. Benzene is an important side product of 1. It might be formed mainly by a hydrogen assisted dealkylation via a cyclohexadienyl type radical as reactive intermediate.
