Polymeric membranes for environmental remediation: A product space model perspective.

The development of polymeric membranes from polymers such as polystyrene (PS), polyvinylchloride (PVC), and their associated family has brought great momentum to the environmental remediation universe, mainly due to their surprisingly diverse and multi-purpose nature. Their usage has surged 20 times in the last half-century and is likely to double again in the coming 20 years. As a result, the polymeric materials economy and commercialization of research become increasingly important as a possible option for a country to boost prosperity while decreasing its reliance on limited raw resources and mitigating negative externalities. This transformation demands a systematic strategy, which involves progress beyond improving the existing models and building new avenues for collaboration. In this work, a sophisticated system, i.e., product space model (PSM), has been presented, explicitly appraising the opportunity space for United Kingdom, Italy, Poland, India, Canada, Indonesia, Brazil, Saudi Arabia, Russia and Colombia for their potential future industrialization and commercialization of polymeric membranes for environmental remediation. The results revealed that UK, Italy, Poland and India are at advantageous positions owing to their close proximity of (distance<2) and their placement in Parsimonious policy, which is the most desired quadrant of Policy Map of PSM, Canada and Indonesia have medium level opportunities, while Russia and Saudi Arabia have opportunities with more challenges to fully exploit the unexploited polymers products in terms of membranes for environmental remediation and prove favorable for export diversification, sustainable economic growth, and commercialization.

Depression In Myocardial Infarction Patients At Ayub Teaching Hospital Abbottabad.

BACKGROUND: There is a considerably high prevalence of depression in post myocardial infarction (MI) patients. This study was designed with an aim to detect depression in patients with acute MI admitted to the CCU at Ayub Teaching Hospital Abbottabad.. METHODS: This descriptive crosssectional study enrolled 246 male and female patients with acute MI. The patients were interviewed on the 3rd day of admission and their answers were marked according to the HADS-D scale. RESULTS: With a cut-off score of 11, the frequency of depression in study participants was 27.24% (n=67). No statistically significant association was found between the age and sex of patients and depression. CONCLUSIONS: Depression is fairly common following acute MI and the management plans should include a consultation with psychiatric for individualized management of depression in post myocardial infarction patients..

Two-port laparoscopic cholecystectomy--a new technique.

Laparoscopic cholecystectomy is now the procedure of choice in all the gall bladder diseases and there is increase in the skills of surgeons with newer equipment. Normally the laparoscopic cholecystectomy is performed by using four ports or three ports. Two ports laparoscopic cholecystectomy is rarely performed as it demands greater expertise and skills. Also this technique is less expensive and less scar formation than four port laparoscopic cholecystectomy. We present a case of a middle aged female who underwent successfully laparoscopic cholecystectomy by using only two ports.
