    Notes: The effects of quisqualic acid lesions of the nucleus basalis magnocellularis on short-term memory capacities of the rat have been investigated using the delayed matching and non-matching to position tasks. The lesions do not disrupt performance of either task by pretrained animals, but do disrupt the ability to acquire the non-matching contingency, and to reverse to the non-matching task when trained on the matching task. The unidirectional nature of the reversal deficit has been replicated. The generalized disruption of performance of either task by the muscarinic antagonist scopolamine was comparable in lesioned and control rats. The lesions were associated with extensive loss of acetylcholinesterase staining in the basal forebrain and in the neocortex, and 55% depletions of choline acetyltransferase activity in the neocortex but not in the hippocampus. These observations demonstrate that the cholinergic projection from nucleus basalis to the neocortex is not critical for normal short-term memory, but that lesions involving this system do disrupt specific types of conditional discrimination learning.

    DIVIDEND POLICY AND ITS RELATIONSHIP TO INVESTMENT AND FINANCING POLICIES: EMPIRICAL EVIDENCE (1985)

    Notes: In this paper it is argued that dividend policy is not determined as a residual, but rather that firms adopt independent dividend and investment policies. Empirical evidence, based on a questionnaire survey, supports this view. Independent dividend and investment policies are possible because debt finance is usually raised in sufficient quantities to accommodate the financial demands created by dividend and investment decisions.

    Analysis of Leishmania proteinases reveals developmental changes in species-specific forms and a common 68-kDa activity (1987)

    Notes: Abstract The proteinases of three species of Leishmania have been analysed by electrophoresis. Amastigotes of L. mexicana mexicana have several high-activity, low-Mr cysteine proteinases which are absent from log-phase promastigotes of L. m. mexicana and from all developmental stages of the other species analysed (L. donovani and L. major). Low-activity, low-Mr proteinases were present in populations of stationary-phase promastigotes of L. m. mexicana. All three species of Leishmania had higher Mr proteinases, a number of which showed developmental regulation, some of them being stage-specific. Significantly, at all stages of the life cycle in all three species a 68-kDa proteinase was apparent. In its size, sensitivity to inhibitors and ability to bind concanavalin A-agarose, this resembles the major surface protein thought to be present in all Leishmania species and which has recently been reported to possess proteinase activity in L. major promastigotes.

    Notes: Summary Sayur asin is a fermented mustard cabbage product of Indonesia. The cabbage is fermented naturally in the presence of brined water taken from boiled rice. Fermentation was characterized by a sequential growth of the lactic acid bacteria, Leuconostoc mesenteroides, Lactobacillus confusus, Lactobacillus curvatus, Pediococcus pentosaceus, and Lactobacillus plantarum. Starch degrading species of Bacillus, Staphylococcus and Corynebacterium exhibited limited growth during the first day of fermentation. The yeasts, Candida sake and Candida guilliermondii contributed to the fermentation. Lactic acid, acetic acid, succinic acid, ethanol and glycerol were products of fermentation. Glucose, generated by the degradation of rice starch and maltose, was metabolized by the species that grew.

    Assessment of gallbladder function using ceruletide in oral cholecystography (1985)

    Abdominal imaging 10 (1985), S. 97-105

    Notes: Abstract A dose of 0.3 μg/kg body weight of ceruletide was assessed for its effect on gallbladder contraction and bile duct delineation following oral cholecystography. Nausea, vomiting, and abdominal pain sometimes occurred after ceruletide. No relationship was found after ceruletide administration between the radiologic appearances of the biliary tract and reproduction of the patients' biliary-type symptoms. Ceruletide cholecystography is regarded as an inaccurate investigation of biliary tract function.

    Ultrasonic evaluation of solid-state welds (1988)

    Notes: Abstract Ultrasonic techniques for evaluating the quality of solid-state weld interfaces have been investigated over the past several years. Promising results have been obtained on a variety of solid-state welds by extracting features from the ultrasonic wave forms and applying pattern recognition algorithms to separate acceptable from unacceptable welds. The general conclusion is that the ultrasonic features most sensitive to interfacial bonding are those dependent on high frequencies. However, no single feature has been discovered that is adequate to yield separation of good vs. poor welds, since the microstructural response is also frequency dependent. Given the increase in sensitivity and resolution with high-frequency ultrasonic evaluation, selected specimens have been examined with acoustic microscopy. These specially prepared samples were inspected with focused transducers at frequencies in the 35–75 MHz range. The reflections observed indicated bond quality to vary in discrete regions with good and poor regions distributed across the diameter. Corresponding variations in the degree of bonding have been observed on the fracture surfaces of mechanically-tested specimens. The development of both low- and high-frequency acoustic microscopy has led to the possibility of sensing and imaging subtle changes in the reflection coefficient of the bond line. These acoustic images will improve our understanding of the mechanisms involved in evaluating solid-state bonds.
