Money Supply Function for Bangladesh: An Empirical Analysis
No full textThe study had empirically tested the money supply function for Bangladesh using annual time series data. Authors observed that high-powered money played a very significant role in the money supply process of Bangladesh, particularly with respect to the narrow money supply M1, thus providing some support for the monetarist model. However, beyond the monetarist view, additional variables in the light of the Keynesian and structuralist analysis, such as bank rate, external resources, and financial liberalization need to be taken into account in understanding the money supply process of the country. Other aforesaid variables were also found to exert some influence on the broad money supply in Bangladesh. However, given the poor performance of the narrow money model and the existence of multicollinearity problem in both models, the estimated results, even for the broad money model, needed to be interpreted with caution.
Deletion of nine carboxy-terminal residues of the Rubisco small subunit decreases thermal stability but does not eliminate function
No full textAbstractA recent X-ray crystal structure of ribulose-1,5-bisphosphate carboxylase/oxygenase from the green alga Chlamydomonas reinhardtii lacks 13 carboxy-terminal residues of the small subunit. To determine the importance of this divergent region, a non-sense mutation was created that removes nine residues. This engineered gene was transformed into a Chlamydomonas strain that lacks the small-subunit gene family. The resulting holoenzyme has a normal CO2/O2 specificity but decreased carboxylation Vmax. Whereas wild-type enzyme retained most of its carboxylase activity after a 10-min incubation at 55°C, the mutant enzyme was inactivated. Thus, although disordered or divergent, the carboxy terminus is required for maximal activity and stability

No full textMacro Economy of a Least Developed Country: The Case of Bangladesh
No full textBangladesh is one of the least developed countries. The economy of Bangladesh suffers from both supply side and demand side problems. This study has been undertaken with a view to investigate macro economic conditions of the country over the two sub periods period a) Sub period-1: Macroeconomic policy under administrative control i.e. 1976-77 to 1989-90; b) Sub period-2: Macroeconomic policy under reform measures i.e. 1990-91 to 2004-05. The study doesn’t find full applicability of either Keynesian or Monetarist view of the macro model for this country. Authors’ suggested that the performance of the Bangladesh economy is a mixture of accomplishment and failure, not significantly different from that of the majority of poor less developed countries and thus a coordinated approach to fiscal, monetary and exchange rate and debt management policy is required to achieve the long-term goal and sustainable economic growth with inflation within control. The first section of the paper provides the background to the literature review. Section two outlines the objective and explains the research methodology applied by gathering quantitative data. Section three explains the analysis of the data and results and section four provides policy implications and finally concluding comments.
Non Photochemical Quenching mechanism in higher plants and in the unicellular alga Chlamydomonas reinhardtii
No full textLight is a necessary ecological factor for oxygenic photoautotrophic organisms. Plants and algae require light for life but it can sometimes become a limiting factor or even cause stress events. Among the different mechanisms evolved to cope with excessive light, the Non Photochemical Quenching (NPQ) seems to be the most efficient process in both plants and algae. The NPQ value can be attributed to three different components (qE, qT and qI). A central problem for eco – physiology is the quantification of the partitioning of the excitation energy into the different mechanisms.
To investigate the variability in the extent of the three components on external parameters, different experiment were performed. My research showed that utilizing inhibitors or mutants lines of Arabidopsis a variation in the components was inducted. The analysis of the fluorescence parameters were further developed and in this work a revised energy partition approach will be proposed.
Moreover, seen that it is very important avoid light stress situation this research proposed the NMR (Nuclear Magnetic Resonance) as a useful tool in the detection of stress situation in vegetal extracts.
In regard to Chamydomonas reinhardtii not so many information are collected on the NPQ. Interestingly, analyses of a suppressor of the npq4 mutation seemed to partly restore the wild-type
NPQ value. This suggests a role not only for protein LHCS3 , but also for LHCSR1
