| 1 | MULTIPLIERS AND TENSOR PRODUCTS OF WEIGHTED L^p-SPACES显示文摘Let G be a locally compact unimodular group with Haar measure rmdx and ω be the Beurling’s weight function on G (Reiter, [10]). In this paper the authors define a space Aωp,q (G) and prove that Aωp,q (G) is a translation invariant Banach space. Fur- thermore the authors discuss inclusion properties and show that if G is a locally compact abelian group then Aωp,q (G) admits an approximate identity bounded in Lω1 (G). It is also proved that the space Lωp (G) Lω1 Lωq (G) is isometrically isomorphic to the space Aωp,q (G) and the space of multipliers from Lωp (G) to Lq-1, (G) is isometrically isomorphic to the dual of the space Aωp,q (G) iff G satisfies a property Ppq. At the end of this work it is showed that if G is a locally compact abelian group then the space of all multipliers from Lω1 (G) to Aωp,q (G) is the space Aωp,q (G). | S.

| 2 | EXPERIMENTAL STUDY ON BED SHEAR STRESS AND SEDIMENT TRANSPORT IN A MEANDERING LABORATORY CHANNEL显示文摘An experimental study was carried out to investigate bed shear stress of a flow boundary layer with meandering features and sediment transport in a meandering channel. By measuring the shear stress distribution with hot-film sensors, the stability of the fluid-bed interface and the characteristics of the bed features were investigated experimentally in a laboratory model for free-surface flow over an erodible bed. The experimental results are presented in two parts. First, experimental observations of meander evolution due to inhomogeneous distribution of boundary layer meander features are qualitatively described in terms of the shear stress distribution. Second, an empirical relation is proposed for the shear stress distribution measured with WTG-50 hotfilmanemometer at the wavy iron bed. The sediment transport rate measured in the meandering channel in a laboratory flume was used to evaluate and compare the sediment transport formulae of Shield (1936), Meyer-Peter and Mller (1948), Einstein (1950), and Bagnold (1966). The sedimentation rates computed using these formulae were found to be generally higher than those observed in the laboratory. However, the Einstein formula yields these rates closest to the measured ones but with an over-prediction of 64.5% in general. Using the experimental observations, empirical formulae were also developed for predicting the sediment transport rate and the meander planforms for a specific condition. | L. YILMAZ1, Vijay P.

| 5 | Thermodynamics of Stability Constant of Binary Complex of Nicotinamide with Mn^(++)显示文摘The stability constants of the binary complexes of Mn2+ with nicotinamide (NA) were determined from potentiometric pH titrations data at 15.0 , 25.0 and 35.0oC and I = 0.1,0.2,0.4 mol L-1 (NaClO4). The formation of binary 1:1 , 1:2 NA-Mn complexes at three different temperatures and the influence of three different ionic strength on their stability were reported. The thermodynamic parameters (DGof, DSof, DHof) for the complex formation reaction were estimated from stability constant at different temperatures. | Tuba SISMANOGLU* Istanbul University , Engineering Faculty Department of Chemistry , 34850, Avcilar-Istanbul, Turkey | 2003 | Chinese Chemical Letters2003，14，11： | 1 |
| 6 | Effect of growth hormone,hyperbaric oxygen and combined therapy on the gastric serosa显示文摘AIM:To investigate the role of growth hormone(GH),hyperbaric oxygen therapy(HBOT) and combined therapy on the intestinal neomucosa formation of the gastric serosa.METHODS:Forty-eight male Wistar-albino rats,weighing 250-280 g,were used in this study.The rats were divided into four groups(n = 12):Group 1,control,gastric serosal patch;Group 2,gastric serosal patch + GH;Group 3,gastric serosal patch + HBOT;and Group 4,gastric serosal patch + GH + HBOT.Abdominal access was achieved through a midline incision,and after the 1-cm-long defect was created in the jejunum,a 1 cm × 1 cm patch of the gastric corpus was anastomosed to the jejunal defect.Venous blood samples were taken to determine the insulin-like growth factor 1(IGF-1) and insulin-like growth factor binding protein 3(IGFBP-3) basal levels.HBOT was performed in Groups 3 and 4.In Groups 2 and 4,human GH was given subcutaneously at a dose of 2 mg per kg/d for 28 d,beginning on the operation day.All animals were sacrificed 60 d after surgery.The jejunal segment and the gastric anastomotic area were excised for histological examination.The inflammatory process,granulation,collagen deposition and fibroblast activity at the neomucosa formation were studied and scored.Additionally,the villus density,villus height,and crypt depth were counted and recorded.The measurements of villus height and crypt depth were calculated with an ocular micrometer.New vessel growth was determined by calculatingeach new vessel in a 1 mm 2 area.RESULTS:In the histological comparison of groups,no significant differences were observed between the control group and Groups 2 and 3 with respect to epithelialization,granulation,fibroblastic activity and the inflammatory process,but significant differences were present between the control group and all others groups(Groups 2-4) with respect to angiogenesis(P < 0.01) and collagen deposition(P < 0.05,P < 0.01).Significant differences between the control group and Group 4 were also observed with respect to epithelialization and fibroblastic activity(P < 0.01 and P < 0.05,respectively).There were significant differences in villus density in all of groups compared with the control group(P < 0.05).Crypt depth was significantly greater in Group 4 than in the control group(P < 0.05),but no other groups had deeper crypts.However,villus height was significantly longer in Groups 2 and 4 than in the control group(P < 0.05).The comparison of groups revealed,significant difference between control group and Groups 2 and 4) with respect to the levels of IGF-1 and IGFBP-3(P < 0.01) 3 wk after the operation.CONCLUSION:HBOT or GH and combined therapy augmented on neomucosal formation.The use of combined therapy produced a synergistic effect on the histological,morphological and functional parameters. | Gokhan Adas Mine Adas Soykan Arikan Ahu Kemik Sarvan Akin Savas TokluDepartment of Underwater and Hyperbaric Medicine Istanbul Faculty of Medicine 34091 Istanbul Turkey Selva Mert Gul Barut Sedat Kamali Bora Koc Firat Tutal | 2013 | World Journal of Gastroenterology2013，19，19： | 1 |
| 7 | Predictive Modeling and Expectable Loss Analysis for Borrower Defaults of Mortgage Loans显示文摘Home mortgage loan lending firms are exposed to many business risks.This paper focuses on the mortgage loan borrower risks and proposes a prospective loss analysis approach in regard to loan repayment defaults of borrowers.For this purpose,a predictive modeling is presented in three stages.In the first stage,occurrence of borrower defaults in a mortgage loans portfolio is modeled through the generalized linear models(GLMs)type regressions for which we specify a logistic distribution for default events.The second stage of modeling develops a survival analysis in order to estimate survival probability and hazard rate functions for individual loans.Ultimately,an expectable loss amount model is presented in the third stage as a function of conditional survival probabilities and corresponding hazard rates at loan levels.Throughout all modeling stages,a large and real data set is used as an empirical analysis case by which detailed interpretations and practical implications of the obtained results are stated. | Omer L.Gebizlioglu A.Belma Ozturkkal Kadir Has University Istanbul Turkey | 2018 | Journal of Modern Accounting and Auditing2018，14，5： | 0 |
