Financial Sector Reforms and International Trade Competitiveness: A Case Study of Pakistan
This paper explores the relationship between financial development and international trade competitiveness in the case of Pakistan. An earlier study on this issue, Hanif and Jafri (2008), has some empirical limitations as it is based on Engle-Granger (1987) two steps procedure while dealing with multiple variables regressions. In this study we have used ARDL model by Pesaran, Shin and Smith (1999). We have also applied Johansen test for cointegration and checked the robustness of results established by the ARDL model. We have estimated the cointegration vector using Stock and Watson (1993) dynamic OLS method. We find a stable long run positive relationship between international trade competitiveness of Pakistan and its financial sector development. The estimated external finance elasticity of international trade competitiveness of textile sector in Pakistan is found to be 0.26 which is significantly higher than 0.17 estimated by Hanif and Jafri (2008).Financial Development, Competitiveness
Some biochemical constituents and the calorific values of different regions of the body musculature of pond murrel Channa punctatus Bloch
A study of the distribution of some chemical constituents in the musculature of Channa punctatus Bloch showed it to be fairly heterogeneous. The increase in the levels of protein, fat, ash, total carbohydrates, glycogen, RNA, DNA and cholesterol towards the posterior region of the fillet was the result of increase in the number of cells per unit weight of the sample and in the concentration of myocommata. The distribution of water in the musculature was inversely related to that of the fat. The concentration of protein appeared to be associated with the RNA level. The posterior region of the fillet exhibited more calorific value than the anterior region
AMCTD: Adaptive Mobility of Courier nodes in Threshold-optimized DBR Protocol for Underwater Wireless Sensor Networks
In dense underwater sensor networks (UWSN), the major confronts are high
error probability, incessant variation in topology of sensor nodes, and much
energy consumption for data transmission. However, there are some remarkable
applications of UWSN such as management of seabed and oil reservoirs,
exploration of deep sea situation and prevention of aqueous disasters. In order
to accomplish these applications, ignorance of the limitations of acoustic
communications such as high delay and low bandwidth is not feasible. In this
paper, we propose Adaptive mobility of Courier nodes in Threshold-optimized
Depth-based routing (AMCTD), exploring the proficient amendments in depth
threshold and implementing the optimal weight function to achieve longer
network lifetime. We segregate our scheme in 3 major phases of weight updating,
depth threshold variation and adaptive mobility of courier nodes. During data
forwarding, we provide the framework for alterations in threshold to cope with
the sparse condition of network. We ultimately perform detailed simulations to
scrutinize the performance of our proposed scheme and its comparison with other
two notable routing protocols in term of network lifetime and other essential
parameters. The simulations results verify that our scheme performs better than
the other techniques and near to optimal in the field of UWSN.Comment: 8th International Conference on Broadband and Wireless Computing,

Some changes in the physical qualities of muscle lipid of the freshwater murrel, Ophicephalus striatus (bloch.) during storage
The present communication reports the changes in the specific gravity, coefficient of viscosity, fluidity and surface tension of the muscle lipid of O. striatus, a common freshwater murrel, when stored at room temp (32 ± 2°C) The specific gravity of muscle lipid was found to rise from 0.894 to 0.912 during the first 25 days of storage but registered the highest (0.925) when stored for 50 days. Surface tension seemed to rise with the duration of storage. This was, presumably, due to an increase in the forces with which the molecules in the surface of the lipid tended to compress the molecules below to the smallest possible volume. During the period of storage marked changes seemed to occur in the direction of an increase in the value of the coefficient of viscosity and a reciprocal decline in the fluidity. Evidently, the observed increase in the viscosity seemed to be the result of increased internal friction between different molecular layers of the lipid, whereas a decline in the fluidity was perhaps the consequence of its inverse correlation with the coefficient of viscosity
Some physical properties of the muscle lipid of two freshwater teleosts, Ophicephalus striatus (Bloch.) and Clarias batrachus (Linn.)
Various physical properties (viscosity, fluidity, surface tension and specific gravity) have been determined for muscle lipids of Ophicephalus striatus and Clarias batrachus. Results are presented and the methods used in determination noted. The physical parameters studied are found to be species-specific
Effect of Listening to A Relaxing Water Sound for Fifteen Minutes On Traumatic Stress Subjects’ Immediate Stress Levels and Electroencephalograms
BACKGROUND: Music and calmness are noteworthy stimulators that significantly affect mental health. Listening to relaxing sounds activates the feeling of wellbeing. The present study aimed to analyze the effect of closed eyes brief exposure to a relaxing water sound on Electroencephalogram (EEG) in pre and post-test states. METHODOLOGY: A total of 20 traumatic stress subjects were included to participate in this study. The subjects were requested to be seated with eyes closed while the sound of water flowing was played for 15 min in between (before and after) the EEG recordings. A subsection of the Sadaf Stress Scale (SSS) i.e. traumatic stress scale was used to assess the traumatic stress and muse (SCR_014418) monitor headband was utilized for EEG evaluation i.e. Alpha waves, Beta waves, Theta waves & Delta waves. RESULTS: Significantly increased theta wave & alpha waves were found after the listening of relaxing water sound in the eyes-closed state. While no significant change was observed in beta & delta waves. Conclusion: The results of this study suggest that exposure to the sound of water flowing quietly significantly generates alteration in brain waves. Although, the applied stimulators were for a brief period changes in frequencies suggest if applied for a longer period it could generate a relaxation state
Thymosin alpha 1 in combination with interferon alpha and ribavirin in chronic hepatitis C patients who are non-responders or relapsers to interferon alpha plus ribavirin
Objective: Interferon alpha (IFN-alpha) with or without ribavirin is an approved therapy for patients with chronic hepatitis C. However, a sustained response is achieved in less than 40% of all treated cases. Retreatment of relapsers or non-responders usually fails. Thymosin alpha 1 (Ta-1) is a polypeptide with immunomodulatory properties that has been suggested to increase response rates in patients with chronic hepatitis C. The aim of present study was to evaluate the efficacy of a novel triple regimen which includes Ta-1 for relapsers and non-responders to the combination of TA-1 and ribavirin.Methods: In the present study, 11 patients who relapsed (n=5) or did not respond (n=6) to previous INF-alpha-based therapy were retreated with combination Ta-1, INF-alpha and ribavirin for 12 months, and followed up for a further six months.Results: Four out of five relapsers had a sustained response. One of the non-responders cleared the HCV RNA during the post-treatment follow-up. Minor adverse effects were observed during treatment with this combination therapy and no dose reduction or discontinuations were needed.CONCLUSION: This data suggests that thymosin alpha 1 may add to the efficacy of INF-alpha plus ribavirin in the retreatment of relapsers or non-responders to previous INF-alpha-based hepatitis C therapy
