ABSTRACT
This study aimed to investigate anaerobic co-digestion of palm oil mill effluent (POME) with cassava peels (CP) and cabbage waste (CW) for biomethane production. The anaerobic digestion (AD) in 10L capacity bioreactors loaded separately with three different ratios (3L/ 520g, 3L/ 600g and 3L/ 680g) of POME/CP, POME/CW and POME only (control) was operated under ambient temperature (25 - 36?C) and pH range of 6.5 - 8.5 for 45 days. Standard methods were adopted in the characterization of the bioreactor feeds and microbiological study. The biomethane content of the biogas was determined using Gas Chromatography (GC). The results showed the presence of Escherichia coli, Staphylococcus, Pseudomonas sp, Bacillus sp Salmonella sp among others. Fungal isolates identified include Saccharomyces, Aspergillus, Rhizopus, Penicillum, and Geotrichum species. The mean cumulative biogas yield recorded in bioreactors charged with POME/ CP 520g, POME/ CP 600g, POME/ CP 680g and POME/CW 520g, POME/CW 600g, POME/CW 680g were 7.08, 5.18, 9.06, 9.13, 9.28 and 8.33 dm3, respectively, whereas POME alone (control) was 4.64 dm3. The best performance in biogas yield was exhibited by POME/CW 600g (9.28dm3), and the highest percentage biomethane content (68.80%). Analysis of variance (ANOVA) revealed a significant difference (P ? 0.05) in biogas yield in all the treatments compared to control (POME alone) except in POME/CP 3L: 520g and POME/CP 3L: 600g. The results have shown that biogas production and biomethane content could be efficiently improved via co-digestion process, depending on the substrates used as feedstock.
ABSTRACT
Background: A quality of life (QoL) assessment tool needs to be translated and validated in the language of the participants to whom it is administered. Therefore, the oral health impact profile-14 (OHIP-14) scale, developed originally in English, has been translated into different languages like Hindi, Gujrati, etc. The Marathi version of OHIP-14 will be useful to assess in regions where the Marathi language is prominently spoken. Thus, the present study was carried out to translate and validate the Marathi version of the OHIP-14 instrument to measure the oral health-related quality of life. Aims & Objectives: To translate and validate the English Version of the OHIP-14 instrument in the Marathi Language. Materials and Methods: This was a descriptive cross-sectional study in which 128 participants were selected through a convenient sampling method. The English version of the OHIP-14 was translated using the forward-backward translation technique, and participants were given English and the Marathi versions of the OHIP-14 questionnaire. The filled questionnaires were subjected to statistical analysis. Result: The difference in mean scores was not statistically significant(p=0.828). Pearson’s correlation coefficient test was 0.999, suggesting that the translated Marathi version is highly correlated with the original English version. Conclusion: The Marathi version of OHIP-14 is a valid, and reliable instrument for assessing QoL among the population who speak Marathi.
ABSTRACT
Background:Emergency medical service has been a well-know n subject of discussion in India where the population is vast and the health care system is inadequate. Essential drugs are a category of drugs that are needed during the golden hour of saving a patient’s life. It becomes necessary that time, when a simple drug can save the life of a patient, a competent health care provider, is needed to administer the drug to the patient. In such a situation, any health care provider in the vicinity of the person who needs medical assistance must get an alert so that the health care provider can reach the site of the emergency and provide assistance. EMS belt is a system in which with the help of a mobile application, any person in case of a medical emergency can get service from a nearby health care provider within a few minutes. The concept is to raise an alarm alerting the nearby health care practitioners about the person in need of medical assistance. This concept is promising with the advantage that it doesn’t need any special manufacturing of the device. Conducting trials on this concept shall yield good observations and produce hopes for a cost-effective EMS system in India.
