Pub Date Free Form 1978/ Volume 30 Issue 3 Start Page 55 Other Pages 59 Notes Place of Publication ISSN/ISBN 0007-523X Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Since cannabis products are generally administered by smoking, it is of importance to get a better understanding of the effects of the smoking process on cannabinoids. Several investigators have studied the conversions of cannabinoids during smoking. However, the information available remains limited and even contradictory. Several reasons can be indicated for this discrepancy. The pyrolytic products of the cannabinoids are masked by the bulk of the substrate which is smoked. On the other hand, a relative change in the composition of the cannabinoids after smoking does not necessarily implicate a mutual conversion, which is however, a conclusion generally observed in literature. Moreover, the experimental techniques used by different research groups are very diverse: except for the material which is to be smoked and which is subject to large variations (marijuana, hashish, cannabis extracts mixed with tobacco, which is often pre-treated), the smoking-techniques also differ to a great extent (e.g., cigarette, pipe, water-pipe). The only common feature of these techniques is that cannabis is subjected to a thermal treatment. This situation calls for additional, more fundamental insight into the processes taking place during the smoking of cannabinoids. It was hoped that comparison of the products formed by smoking cannabidiol (I, CBD) through a water-pipe which is the general way of smoking by heavy cannabis users in the eastern countries, and the products formed by treatment of CBD under several pyrolytic conditions may contribute to reach this goal.

Economics of long-distance transmission, storage, and distribution of heat from nuclear plants with existing and newer techniques	1978	Margen, Peter H., AB Atomenergi, Studsvik, Fack 611 01 Nykoping	Read more...

Nucl Technol Pub Date Free Form 1978/04 Volume 38 Issue 2 Start Page 192 Other Pages 203 Notes Place of Publication ISSN/ISBN 0029-5450 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Conventional and newer types of hot-water pipes are applied to the bulk transport of reject heat from central nuclear power plants to the district heating network of cities or groups of cities. With conventional pipes, the transport of 300 to 2000 MW of heat over distances of 30 to 100 km can be justified, while with newer pipe types, even longer distances would often be economic. For medium-size district heating schemes, low-temperature heat transport from simple heat-only reactors suitable for closer location to cities is of interest. For daily storage of heat on district heating systems, steel heat accumulators are currently used in Sweden. The development of more advanced cheaper heat accumulators, such as lake storage schemes, could make even seasonal heat storage economic. Newer distribution technology extends the economic field of penetration of district heating even to suburban one-family house districts. With proper design and optimization, nuclear district heating can be competitive in a wide market and achieve very substantial fossil-fuel savings.

The sulphur:nitrogen ratio of conifer foliage in relation to atmospheric pollution with sulphur dioxide	1977	Dept. Forestry Natural Resources, Univ. Edinburgh	Read more...

Plant Soil Pub Date Free Form 1977/ Volume 47 Issue 1 Start Page 89 Other Pages 102 Notes Place of Publication ISSN/ISBN 0032-079X Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract The S:N ratio of the current foliage of two commonly planted conifers, Sitka spruce (Picea sitchensis (Bong.) Carr.) and Scots pine (Pinus sylvestris L.) was determined for areas known to have unpolluted atmospheres. The mean values of the ratio (0.034 and 0.028 respectively) were used to compare similar foliage from a) an industrialised area, and b) a series of transects radiating from a brickworks chimney. The established ratios were used to predict foliar S concentrations and the greater amounts found were ascribed to foliar absorption of atmospheric S. The 'excess' S was negatively related to distance from the supposed source, and also to needle weight which itself was positively related to distance. It is concluded that this measure derived from the S:N ratio is theoretically and practically a more sensitive indicator of the accumulation of S in conifer foliage exposed to atmospheric pollution than the analysis for elemental S or the SO4-ion alone.

The elaboration of bases of evaluation needed for the purifying of waste water in the fruit and vegetable processing industry	1977		Read more...

Fluessiges Obst Pub Date Free Form 1977/ Volume 44 Issue 4 Start Page 132 Other Pages 143 Notes Place of Publication ISSN/ISBN Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract The analysis of waste water which is made to elaborate the phases for an evaluation which will permit the processing of this water is more difficult to make in fruit and vegetable processing plants than in other industrial branches because the continuous change of the raw products which occurs during the year leads to extremely high fluctuations of the quantities and of the composition of the waste water. Because of this it becomes necessary to make analyses during several periods which must be distributed over the whole year, depending on the operating plan of the plant. The most important waste water analyzing operations are the measuring of the waste water quantities and the determination of the physical and chemical composition of this water. It is important that the quantity of the samples which are taken corresponds in proportion to the waste water quantity, this condition must be taken into account if significant results of analysis are to be obtained. It is necessary to make certain preparations in the factory before waste water analyses can be made; the mounting of a device to measure and take samples in the waste water pipe or channel is a part of these preparations. The mobile waste water measuring device used by the 'IWL' (Institute for the Prevention of Pollution of Water and Air) which is equipped with an echo sounding apparatus and which controls simultaneously the automatic sample collecting device has given good results when it was employed during practical operations. The different sorts of waste water resulting from the different productions are polluted to various degrees; sometimes these pollutions are composed partly of fruit and vegetable juices, of carbohydrates and of sugar solutions. The interpretation of the results of analyses of waste water produced by fruit and vegetable processing plants permits to determine certain proportional fluctuations of the waste water composition which are shown by diagram lines indicating the quantities and the degrees of pollution throughout the year. The bases of evaluation according to which the necessary waste water purifying operations are determined are elaborated on the base of the results of measurements and analyses which are obtained during all the analyzing periods; summaries of the daily waste water quantities and of the composition of the pollution as well as summaries of the nutritious matter contained in the waste water which are written in the form of a condensed report of examination are an important part of the mentioned bases of evaluation.

Anesthesiology Pub Date Free Form 1977/ Volume 46 Issue 4 Start Page 286 Other Pages 289 Notes Place of Publication ISSN/ISBN 0003-3022 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Medical gases and water were sampled and tested for purity prior to the opening of a 176 bed addition to a 450 bed general hospital. Contamination was found. In delivered oxygen, compressed air, and nitrous oxide, this consisted for a volatile hydrocarbon at an initial concentration of 10 parts per million and a dust of fine gray particulate matter. In water from new taps bacterial contamination with as many as 400,000 organisms per 100 ml was present. All these contaminants were considered potential hazards to patient safety. Studies were done to help delineate the nature and origin of these contaminants. Each contaminant was eventually largely eliminated by purging the respective pipeline systems with continuous flows. Planners, builders, and responsible medical personnel must be aware of the potential for such hazards in a new hospital building.

With recent increases in commercial, military, and sport diving to deeper depths, inner ear disturbances during these exposures have been noted more frequently. Studies of inner ear physiology and pathology during diving indicate that the causes and treatment of these problems differ depending upon the phase and type of diving. Humans exposed to simulated depths of up to 305 meters without barotrauma or decompression sickness develop transient, conductive hearing losses with no audiometric evidence of cochlear dysfunction. Transient vertigo and nystagmus during diving have been noted with caloric stimulation, resulting from the unequal entry of cold water into the external auditory canals, and with asymmetric middle ear pressure equilibration during ascent and descent (alternobaric vertigo). Equilibrium disturbances noted with nitrogen narcosis, oxygen toxicity, hypercarbia, or hypoxia appear primarily related to the effects of these conditions upon the central nervous system and not to specific vestibular end-organ dysfunction. Compression of humans in helium-oxygen at depths greater than 152.4 meters results in transient symptoms of tremor, dizziness, and nausea plus decrements in postural equilibrium and psychomotor performance, the high pressure nervous syndrome. Vestibular function studies during these conditions indicate that these problems are due to central dysfunction and not to vestibular end-organ dysfunction. Persistent inner ear injuries have been noted during several phases of diving: 1) Such injuries during compression (inner ear barotrauma) have been related to round window ruptures occurring with straining, or a Valsalva's maneuver during inadequate middle ear pressure equilibration. Divers who develop cochlear and/or vestibular symptoms during shallow diving in which decompression sickness is unlikely or during compression in deeper diving, should be placed on bed rest with head elevation and avoidance of maneuvers which result in increased cerebrospinal fluid and intralabyrinthine pressure. With no improvement in symptoms after 48 hours, exploratory tympanotomy and repair of a possible labyrinthine window fistula should be considered. Recompression therapy is contraindicated in these cases...

Pub Date Free Form 1976/10 Volume 5 Issue 4 Start Page 400 Other Pages 405 Notes Place of Publication ISSN/ISBN 0047-2425 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract A 0.09 ha field prototype of a simultaneous waste heat and waste water disposal system was constructed and instrumented. Data are reported for soil, pipe, soil surface, and air temperatures; heat loss (0.068-0.117 cal cm-2 min-1); and soil thermal conductivity (3.61-5.63 mcal [cm sec Â°C]-1). The data are used to evaluate the heat flow theory which is currently being used to predict the land area required for waste heat disposal with a buried hot water pipe network. Predicted heat loss was consistently lower than experimental heat losses. The results of the experiment indicate that substantial improvements need be made in the existing theory to account for the transient heat flow and heat storage.
