How Indonesia's monetary policy affects key variables

The objective of this paper is to examine the determination of interest rates, inflation and nominal exchange rates in Indonesia, and investigate the role of monetary policy in affecting these variables. In the short term, monetary policy can be used to protect domestic interest rates from the destabilizing influence of speculative capital flight. In the long run, monetary policy can help lower domestic nominal interest rates by maintaining low inflation and dampening expectation about depreciation. The potential for reducing interest rates through monetary expansion is limited. Domestic inflation is partly a monetary phenomenon but structural factors also affect it. The effects of international inflation are immediate and strong; the effects of wage pushes are smaller and less immediate. Inflation can be reduced to some extent by slowing the growth of money - which strengthens the secondary influence of a slower crawling exchange rate. A managed float is appropriate for maintaining a competitive exchange rate, given the gap between world and domestic inflation caused by structural and monetary factors. Real depreciation of the exchange rate will be necessary to compensate for unanticipated decline in oil income (from lower than expected oil prices).Economic Theory&Research,Economic Stabilization,Environmental Economics&Policies,Macroeconomic Management,Banks&Banking Reform

Novel duplex vapor-electrochemical method for silicon solar cells

Silicon obtained by the SiF4-Na reaction was analyzed by spark source mass spectrometry (SSMS). Silicon samples prepared from induction melted powder were evaluated for electrical properties using four point probe conductivity and thermoelectric methods. SiF4-Na reaction under P sub SiF4 greater than 1 atmosphere. The amount of silicon produced was increased from 25 g per batch (in the glass reactor) to greater than 70 g per batch in the stainless steel reactor. The study of the effects of reaction variables such as P sub SiF4 and maximum temperature attained on the particle size of silicon powder showed that the silicon particle size tends to grow larger with increasing pressure of the SiF4 gas in the reaction system

Novel duplex vapor-electrochemical method for silicon solar cells

Silicon was produced by alternate pulse feeding of the reactants SiF4 gas and liquid sodium. The average temperature in the reactor could be controlled, by regulating the amount of reactant in each pulse. Silicon tetrafluoride gas was analyzed by mass spectrometry to determine the nature and amount of contained volatile impurities which included silicon oxyfluorides, sulfur oxyfluorides, and sulfur dioxide. Sodium metal was analyzed by emission spectrography, and it was found to contain only calcium and copper as impurities

The Effect of Surface Sizing With Starch on Tensile & Tear

This survey of literature concerning surface sizing has been undertaken in an effort to compile in one paper the importance of surface sizing on strength properties, particularly tensile and tear. The use of starch in the modification of surface characteristics of a writing medium may actually be older than the art of paper manufacture itself. A considerable amount of literature on surface sizing showing the effect on surface improvements of the paper sheet is available, but very little work has been undertaken to study the effect of surface sizing on tensile and tear. Both their strength properties increased on surface sizing with low viscosity oxidized potato starch as compared to high viscosity starch, in which the latter case no significant effect was observed. High viscosity starch did not penetrate the sheet of paper, but rather stayed on the surface. This study showed that calendering after sizing operations should be reduced to a minimum to get improved tensile and tear. Otherwise, both these properties are appreciably reduced

Does clinical management improve outcomes following self-Harm? Results from the multicentre study of self-harm in England

Background Evidence to guide clinical management of self-harm is sparse, trials have recruited selected samples, and psychological treatments that are suggested in guidelines may not be available in routine practice. Aims To examine how the management that patients receive in hospital relates to subsequent outcome. Methods We identified episodes of self-harm presenting to three UK centres (Derby, Manchester, Oxford) over a 10 year period (2000 to 2009). We used established data collection systems to investigate the relationship between four aspects of management (psychosocial assessment, medical admission, psychiatric admission, referral for specialist mental health follow up) and repetition of self-harm within 12 months, adjusted for differences in baseline demographic and clinical characteristics. Results 35,938 individuals presented with self-harm during the study period. In two of the three centres, receiving a psychosocial assessment was associated with a 40% lower risk of repetition, Hazard Ratios (95% CIs): Centre A 0.99 (0.90–1.09); Centre B 0.59 (0.48–0.74); Centre C 0.59 (0.52–0.68). There was little indication that the apparent protective effects were mediated through referral and follow up arrangements. The association between psychosocial assessment and a reduced risk of repetition appeared to be least evident in those from the most deprived areas. Conclusion These findings add to the growing body of evidence that thorough assessment is central to the management of self-harm, but further work is needed to elucidate the possible mechanisms and explore the effects in different clinical subgroups

Clinical efficacy and safety of statins in managing cardiovascular risk

Since their introduction in the 1980s, 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) have emerged as the one of the best-selling medication classes to date, with numerous trials demonstrating powerful efficacy in preventing cardiovascular outcomes. As our understanding of low-density lipoprotein cholesterol (LDL-C) and atherosclerosis continues to grow, the concept of ‘lower is better’ has corresponded with a ‘more is better’ approach to statin-based therapy. This review provides a detailed understanding of the clinical efficacy and safety of statins with a particular emphasis on the third generation drug, rosuvastatin

Antibody localization in horse, rabbit, and goat antilymphocyte sera

The localization of antibodies was studied in rabbit, goat, and horse ALS raised by weekly immunization with canine or human spleen cells for 4 to 12 weeks. A combination of analytic techniques was used including column chromatography, electrophoresis, immunoelectrophoresis, determination of protein concentration, and measurement of antibody titers. In the rabbit and goat ALS, virtually all of the leukoagglutinins and lymphocytotoxins were in the easily separable IgG; accidentally induced thromboagglutinins were in the same location. In the rabbit hemagglutinins were found in both the IgG and IgM, whereas in the goat these were almost exclusively in the IgM. The antiwhite cell antibodies were most widely distributed in the horse. The cytotoxins were primarily in the IgG, but the leukoagglutinins were most heavily concentrated in the T-equine globulin which consists mostly of IgA. By differential ammonium sulfate precipitation of a horse antidoglymphocyte serum, fractions were prepared that were rich in IgG and IgA. Both were able to delay the rejection of canine renal homografts, the IgA-rich preparation to a somewhat greater degree. The findings in this study have been discussed in relation to the refining techniques that have been used for the production of globulin from heterologous ALS. © 1970
