AbstractAbstract
[en] To determine the relationship between cannabis abuse and its impact on the short-term outcome and severity of illness. ICD-10 criteria were used for diagnosis of schizophrenia. Severity and type of schizophrenic symptoms were assessed with the help of PANSS. Cases were identified as having problem with cannabis use with the help of section 12 of Schedule for Clinical Assessment in Neuropsychiatry (SCAN) W.H.O. 1994. Amount, duration and frequency of cannabis use was also noted. Patients with cannabis use were younger had shorter duration of illness and earlier age at onset of illness. They exhibited more positive symptoms. A total of 20% cases met ICD-10 criteria of harmful use of cannabinoid, 76% met ICD-10 criteria of cannabinoid dependence syndrome. Schizophrenic patients with comorbid cannabis abuse exhibited more positive symptoms and violent behavior, and may be more likely to lead to dependence in persons with schizophrenia. This has implication for service development to meet the perceived needs of this group. (author)

AbstractAbstract
[en] This report evaluates a simplified technique for estimating methanol emission rates in auto exhaust. The technique, referred to as the FID Bubbled Method or FBM, is based in principle on the fact that, while hydrocarbons are not readily absorbed in water, methanol is. Hence, by using a heated flame ionization detector to measure the organic mass in samples before and after bubbling them in water, the quantity of methanol originally present can be estimated by taking the difference between the measurements. Evaluation of the method was done by comparing methanol measurements using the FBM with measurements made using an established reference method. Results showed poor to fair agreement between the two methods. The FBM appeared better at estimating methanol emission rates from evaporative tests than from exhaust tests and also exhibited better accuracy for samples containing higher levels of methanol

AbstractAbstract
[en] Saururaceae (lizard's tail family) comprises three genera and four species (Saururus chinensis (Loureiro) Baillon. (SC), Gymnotheca chinensis Decne. (GC), Gymnotheca involucrata Pei. (GI) and Houttuynia cordata Thunberg. (HC)) in eastern Asia, and they extend from the most primitive to the most evolutionary levels. The purpose of this study is to examine whether and to what extent the diversity of volatiles can support the accepted evolutionary scheme in Saururaceae for the four species. Volatiles from fresh leaves and flowers of Saururaceae species from different regions were analyzed comparatively by gas chromatography-mass spectrometry (GC-MS). The samples studied showed differences in the volatile profiles of leaves and flowers among the species. In the leaves and flowers, concentrations of all monoterpenes and oxides, all alcohols, all acids and all esters were highest in SC, lowest in HC, and the concentrations of these components for GC and GI were between those of SC and HC. Concentrations of all sesquiterpenes and oxides, all straight chain aliphatic hydrocarbons, all branched aliphatic hydrocarbons, all aldehydes, and all ketones were lowest in SC, highest in HC and the concentrations of these components for GC and GI were between those of SC and HC. The results in this study could support the accepted taxonomical scheme of four species in Saururaceae. (author)

AbstractAbstract
[en] Based on the predictions of the frequencies and the forms of normal oscillations of the molecules of phenol and its derivatives (dioxibenzenes), the necessity is shown to transform the forced field of the above compounds in going from the model of free molecules (gas phase) to the condensed state that takes into account the onset of intermolecular interactions. A number of vibrational frequencies are estimated as characteristic ones, through which it is possible to make the spectral-structural analysis (including different conformations). (authors)

AbstractAbstract
[en] Ethanol synthesis by anoxic root segments from Port Orford cedar (Chamaecyparis lawsoniana (A. Murray bis) Parl.); yellow cedar (Chamaecyparis nootkatensis (D. Don) Spach); Atlantic white cedar (Chamaecyparis thyoides (L.) Britton, Sterns & Poggenb.); western red cedar (Thuja plicata Donn ex D. Don), and incense cedar (Calocedrus decurrens (Torr.) Florin ) was compared to determine whether the amounts that they produced during flooding could contribute the known greater vulnerability of Port Orford cedar to infection by Phytophthora lateralis Tucker & Milbrat. Roots were incubated in water at 5, 15, 25, and 35 °C for 14 days with periodic sampling. After 12 h of anoxic stress, Atlantic white cedar and yellow cedar roots produced equal quantities of ethanol that were about two times more than produced by the other three species, which did not differ from one another. The roots remained anoxic for 14 days, with ethanol concentrations increasing 6 to 11 times depending on the species. After 14 days, Atlantic white cedar remained the highest ethanol producer at two to three times more than the other species, whereas incense cedar yields were the lowest. Yellow cedar, western red cedar, and Port Orford cedar had intermediate levels of ethanol. The similarity in responses of Port Orford cedar to the other species is strong evidence that ethanol is not an important contributor to its known greater vulnerability to P. lateralis infection. In general, root incubation temperature affected ethanol synthesis similarly for all species. Increases in temperature from 5 to 15 °C or 15 to 25 °C doubled the ethanol yields at 12 h. Literature ratings of anaerobic tolerance for these cedars were compared with ratings based on their ethanol yields after 12 h or 14 days of anoxia. The latter rating appears to more closely correspond with the cedars associations to wet, mesic environments and their likelihood of experiencing anoxia via flooding. (author)

AbstractAbstract
[en] It has been demonstrated that flower-like microstructures can be fabricated on a Mg plate using a solution of propylphosphonic acid and HFTHTMS in ethanol. In the presence of propylphosphonic acid, the HFTHTMS is polymerized and then deposited on the surface of the Mg plates during the immersion period. Many flower-like structures were formed on the surface after at least 6 h of immersion, at which point the modified plate became superhydro-phobic. The nano-/micro scale flower-like structure is composed of fluorinated polysiloxane, which acts as a low-surface-energy material. SEM images reveal that the flower-like structure is composed of many thin flakes. It is confirmed that these structures on the surface contain air and result in an ideal structure for obtaining the superhydrophobic surface. This proposed coating method is simple and can be applied to a large sample to fabricate a superhydrophobic surface without expensive instruments. Superhydrophobicity of solid materials has attracted significant attention because it provides strong water repellency and self-cleaning properties. The chemical composition and nano-/microscale structures of the surface are key factors determining the surface properties. Recently, superhydro-phobic surfaces showing high water contact angles (CA) > 150 .deg. and low sliding angles (SA) < 10 .deg. have been the focus of much research because they have many applications in both academic fields and industrial processes

AbstractAbstract
[en] The relationships among varying bore fluid compositions containing ethanol/water were studied. The ethanol composition was varied in the ratio of 0%, 25%, 50%, 75% and 100%. The membrane dope solutions were prepared from 17.25 wt% polyethersulfone (PES), 0.75 wt% polyethylene glycol (PEG), 3 wt% silicon dioxide sol and 78.25 wt% of 1-methyl-2-pyrrolidone (NMP) via dry-jet spinning process. The membranes’ morphology as a result of varying ethanol ratio in the bore fluid composition was characterized and their effects on crude oil/water emulsion separation were evaluated. Results show that the membrane pore size and porosity decreased with increasing ethanol content in the bore fluid mixture, whereas the inner wall thickness of fibers increased. Furthermore, an increase in ethanol concentration also resulted in a slight increase in water contact angle. The use of 100/0 of ethanol/water resulted in UF membranes with the lowest performance. On the other hand, bore fluid mixture containing 25/75 ethanol/water produced membrane with the best performance for crude oil/water separation. Overall, the use of bore fluid mixture containing 25/75 ethanol/water mixture was found to be a powerful way to tune the morphological properties and performance of HF membrane.
