The ability of Climacodon septentrionalis to immobilize and kill a mycophagous nematode (Aphelenchoides sp.) in vitro is described for the first time. Two isolates produced droplets (20–45 μm in diameter) that formed at the apices of tall, stalked, and branching secretory cells (700–

,500 μm tall). On 2% modified malt extract agar, nematodes became enveloped in the droplets, which restricted their ability to move and resulted in complete immobilization and death within several hours of contact. The rate of decomposition of the nematodes varied considerably, with most individuals persisting for weeks whereas others were degraded within several days and appeared to be colonized by dense hyphal growth. This study provides the first documentation of a non-agaricoid fungus producing secretory cells that are able to immobilize nematodes.

Two new partially saturated tricyclic ring systems, , a, , 8, , 10, 10a, 11-octahydro-11-oxodibenz [, ] oxepins (3a and 3), and -thiepins (4a and 4) were synthesized. Compounds 4a and 4 were desulfurized to give a pair of isomeric 2-methylbenzoylcyclohexanes (10a and 10). Deuterated 4a and 4 (11a and 11) were prepared starting from butadiene- (12). The stereochemical features of 3a (trans), 3 (cis), 4a (trans) and 4 (cis) are compared with those of 10a, 10, 11a and 11 on the basis of proton nuclear magnetic resonance data.

The possibility of attenuation of microseismic waves due to the presence of an upward folding of the ocean bottom into the liquid is discussed in this paper. The upward folding of the ocean bottom has been idealized by means of an irregularity in the form of a rectangle intruding into the liquid and the evaluation of the displacement component at any point of the solid medium has been carried out in two stages. First, the change in the incident mode of the surface wave due to the presence of the rectangular irregularity has been determined, and second, the subsequent change of the resulting displacement components due to the termination of the liquid layer and the step change in elevation of the solid medium at the continental margin has been discovered. Finally, numerical calculation has been made to determine the attenuation of the microseismic waves of different periods due to the presence of the rectangular irregularity at the ocean bottom.

Nine isoquinoline alkaloids belonging to the protoberberine, proaporphine and bisbenzyl-isoquinoline series were isolated from Caryomene olivascens (Menispermaceae). Four compounds are new : (-)-2-norlimacine (4), (-)-caryolivine (), (+)-, 2-dehydro-2-norlimacusine () and N-formylstepharine (3). The last one is the first N-formyl derivative to be reported in the proaporphine group. Its biogenetic origin is discussed. Structures were established on the basis of 360 MHz (FT) nuclear magnetic resonance measurements and also by chemical correlation in the case of 3.

One method currently being considered for the disposal of high level radio-active waste is burial in the seabed. When a hot object is buried in soil, the temperature of the soil adjacent to the object is raised and there is transient heat flow away from the object. The rise in the temperature of the soil causes excess pore pressures to be generated and transient pore water diffusion also takes place. A finite element formulation of the coupled heat flow and consolidation problem is presented. The computer implementation of this formulation is found to compare favourably with analytical solutions based on the same physical principles.

As a fundamental study on dibenzothiepins, reaction of 11-phenyl-, 11-dihydrodibenzo [, ] thiepin-11-ol (10) or 11-chloro-11-phenyl-, 11-dihydrodibenzo [, ] thiepin (14) with triphenylmethyl cation or was examined under various conditions. 11-Phenyl-, 11-dihydrodibenzo [, ] thiepin-11-ylium salt (8) was isolated as a black powder (perchlorate) and a green powder (hexachloroantimonate), but BF₄ salt was obtained only as a solution. Treatment of the hexachloroantimonate with excess of was found to result in a novel dehydrocyclization reaction to give selectively , 13-dihydrofluoreno [, a, -, d] [2]-benzothiepin-13-ylium hexachloroantimonate (19). Some discussions were made on the mechanism of the formation of 19.

We observed transients during the isotopic analysis of carbon dioxide, which could not be attributed to mixing processes because of their asymmetry, and to explain these we were led to consider the effects of diffusion on gas flow in the sample line. In particular, we investigated the propagation by diffusion of a concentration anomaly against a steady gas flow. If fractionation of isotopic(or chemical)species at the leak is to cause a change with time of the composition of the gas in the sample reservoir, then the effects of the fractionation must diffuse backwards as far as the gas reservoir.Using a one-dimensional Green's function, we obtained explicit analytical functions for the steady state concentration variation along a connecting tube between the leak and the reservoir, and for the composition variations with time at the leak. It is shown that the isotopic composition in the sample reservoir need not vary with time, even with a fractionating leak, provided that bulk gas velocity in the connecting tube is large enough. It is also shown that the diffusion process in combination with a fractionating leak can lead to the type of transients we observed.

Since 135 years .H.Will Hamburg is one of the leading manufacturers of converting machinery for the paper industry.The company has gained worldwide acknowledgement when introducing cut size sheeters for copy paper. These machines are used worldwide by all well-known paper makers and also in the meantime by smaller paper converting companies.
With regard to folio size sheeter .H.Will was and is reknown for special solutions instead. Based on and with the knowhow of hundreds of cut size sheeters and some hundred folio size sheeters having been delivered, the concept of the Will “global folio size sheeter” type GFS has been developed.
The great technical experience in cutting and transporting paper as well as introducing innovative ideas, new materials and, last but not least, the influence of various customers' requests, which are known to .H.Will from numerous special projects, were the base for development of the GFS folio sheeter.

The phase diagrams of the Ni-Mo- and Ni-W- ternary systems in the region of less than 50mol% were constructed by thermodynamic calculation, based on the data obtained by thermodynamic measurement of the related materials. We found three ternary eutectic points and three or two ternary peritecto-eutectic points as follows:
:L (1365K, 71.mol%Ni-.0mol%Mo-.mol%)=(Ni)++
:L (1355K, 62.mol%Ni-2.mol%Mo-30.mol%)=++
:L (1445K, 42.0mol%Ni-30.mol%Mo-10.3mol%)=(Ni)+NiMo+
:L (1812K, 34.mol%Ni-42.3mol%Mo-.8mol%)+MoB=+
P₂:L (1633K, 42.3mol%Ni-40.4mol%Mo-17.3mol%)+Mo=+
P₃:L (1812K, 53.mol%Ni-33.mol%Mo-12.8mol%)+Mo=NiMo+
:L (1622K, 51.0mol%Ni-31.mol%W-17.4mol%)=(Ni)+W+
:L (1260K, 71.0mol%Ni-.0mol%W-.0mol%)=(Ni)++
:L (1291K, 65.4mol%Ni-4.8mol%W-29.8mol%)=++
:L (2115K, 23.8mol%Ni-43.mol%W-33.mol%)+WB=+
P₂:L (1657K, 48.mol%Ni-33.mol%W-18.0mol%)+=W+
The calculated phase diagrams are expected to be useful for the development of new Ni-based heat-, corrosion- or wear-resistance alloys.

The effect of composition and controlled thermomechanical process parameters on the mechanical properties of HSLA steels is modelled using the Widrow-Hoff's concept of training a neural net with feed-forward topology by applying Rumelhart's back propagation type algorithm for supervised learning, using a Petri like net structure. The data used are from laboratory experiments as well as from the published literature. The results from the neural network are found to be consistent and in good agreement with the experimented results.
