SIGNIFICANCE OF USING UPAMANA PRAMANA IN AYURVEDA

Ayurveda, the ancient Medico Holistic Science, which is comprised of numerous fundamental concepts with basic doctrines. Ayurveda along with its concepts is eternal (Shaswata), and have their own identity which does not require other science to indulge in between. Such fundamental concepts are literally better understood, analyzed and merely utilized in clinical practice only with the proper utility of Pramanas. Pramanas in Ayurveda are means of true knowledge. Acharya Sushruta describe four Pramanas and among the four Pramanas i.e. Pratyaksha (Direct perception), Agama (Teaching of scriptures), Anumama (Inference), Upamana (Analogy). Upamana Pramana is used widely in Ayurvedic literatures. Upamana is having its own importance. Upamana or Aupamya give the knowledge or idea of an object by similar comparison. Acharya Charaka has not included Upamana Pramana under Pramanas but he described it under Vada Marga i.e. technical terms used in Sambasha by Vaidya-Samuha and ultimately helps in attaining valid knowledge, but more than being used in Sambasha, Upamana is having its clinical utility. Upamanas are the analogies or similes that bridge the known to the unknown and after the conceptual system of existing knowledge by modifying and strengthening its associations. Prime intention of such Upamana is incorporating open-ended, forced and visual similes to teach complex concepts and involving students in a creative dynamic though process to enhance understanding of such complex medical concepts. But we have to be very careful about its understanding such analogies, otherwise it may lead to wrong concepts. As said that “An Analogy is like a car, if you take it too far, it breaks downâ€. So here a sincere effort has been made to evaluate and analyze the Upamana Pramana in a simple way in three aspects i.e., physiological, diagnostic, philosophical aspects.

Effect of Packaging and Storage Temperature on Shelf-Life of Minimally Processed Onion (Allium cepa L.)

Minimally processed onion is a ready-to-use onion product offering the consumer a fully usable commodity, without much change to freshness of the produce. Effect of packaging and storage temperature on shelf-life in minimally processed onion was studied. Packaging and temperature play an important role in determining shelf-life in minimally processed onion. Onion pieces approx. 8-10mm thick were cut with a plain, sharp knife and subjected to dip-treatment with the firming agent, calcium lactate (2%), for 5 minutes. The samples were surface-dried and packaged in polypropylene bags of size 250 X 125mm, of variable thicknesses (25, 50 or 75μm) and stored at low temperatures and high RH:8±1°C and 83±2% RH; 10±1°C and 82±2% RH; and, 12±1°C and 80±2% RH. It was found that onion cv. Arka Sona sliced with a plain, sharp knife, pre-treated with 2% calcium lactate, surface-dried and packaged in polypropylene bags sized 250X125mm (50μm thick), and stored at 8+1°C and 83±2% RH retained freshness and nutritive value, were microbially safe and acceptable, with a shelf-life of 14 days at storage

Analysing the Art of Service Quality and Customer Satisfaction of Digital Banking Services: A SEM Approach

Given that India is among the countries with the fastest-growing digital banking service providers globally, the purpose of this research is to examine the relationship between service quality and customer satisfaction when using digital banking through the use of a structural equation model. An organised set of survey questions was created in order to gather information from respondents in India. The study employed a stratified sampling technique to choose possible participants. 232 completed and useable questionnaires were chosen from the distribution to be analysed using AMOS-structural equation modelling (SEM). The findings demonstrated that consumer satisfaction with digital banking is positively and significantly impacted by all of the components of service quality—tangibility, reliability, responsiveness, assurance, and empathy. Customer satisfaction is very strongly impacted by response. Additionally, it has been determined that tangibility has less of an impact on consumer satisfaction. The findings also indicate that digital banking service providers should focus on improving all facets of service quality, with a focus on timeliness and reliability, in order to boost consumer satisfaction.  When providing services to end users and clients of digital banking, researchers, banking authorities, legislators, and financial organisations will need to consider a number of conclusions from this study. Additionally, this implication aids banks in comprehending and creating policies and strategies to enhance India's digital banking services

Effect of Organic Cultivation of Capsicum annuum L. on Soil Microbial Properties under Open-Field and Shade-House Conditions

Two bell pepper (Capsicum annuum L.) varieties, viz., California Wonder and Gangavati Local, were raised under nine completely organic nutrient sources, along with recommended package of practices, and, under completely inorganic nutrient sources. Irrespective of the variety and growing environment, there was substantial increase in total bacterial count (22.97% and 24.98%), population of fungi (20.23% and 20.23%), actinomycetes (36.89% and 36.83%) and mycorrhiza (44.63% and 29.40%) in open-field and shade-house conditions, respectively, in all the nutrient combinations where organic sources were used, compared to the inorganic treatment. All organic nutrient sources used were found to be similar in their effect on soil microbes

Filled Ethylene-propylene Diene Terpolymer Elastomer as ThermalInsulator for Case-bonded Solid Rocket Motors

Ethylene-propylene diene terpolymer (EPDM)-based insulation system is being globallyused for case-bonded solid rocket motors. A study was undertaken using EPDM as base polymer,blended with hypalon and liquid EPDM and filled with fibrous and non-fibrous fillers. Theseformulations were evaluated as rocket motor insulation system. The basic objective of the studywas to develop an insulation system based on EPDM for case-bonded applications. A series ofrocket motor insulator compositions based on EPDM, filled with particulate and fibrous fillerslike precipitated silica, fumed silica, aramid, and carbon fibres have been studied for mechanical,rheological, thermal, and interface properties. Compositions based on particulate fillers wereoptimised for the filler content. Comparatively, fumed silica was found to be superior as fillerin terms of mechanical and interface properties. Addition of fibrous filler (5 parts) improved thepeel strength, and reduced the thermal conductivity and erosion rate. All the compositions wereevaluated for sulphur and peroxide curing. Superior mechanical properties were achieved forsulphur-cured products, whereas peroxide-cured products exhibited an excellent ageing resistance.Rocket motors were insulated with optimised composition and propellant cast, and the motorswere evaluated by conducting static test in end-burning mode.Defence Science Journal, 2008, 58(1), pp.94-102, DOI : http://dx.doi.org/10.14429/dsj.58.162

Effect of Organics and Inorganics on Yield Parameters in Bell Pepper under Open Condition

Investigations were carried out to study the effect of organics on yield and fruit quality parameters in bell pepper grown under open condition. Split plot design, with three replications, was adopted taking two bell pepper varieties, viz., California Wonder and Gangavati Local (as main-plot treatments) and nutrient source (as sub-plot treatments). Variety California Wonder performed better with respect to yield parameters compared to the Local variety. Application of 100% recommended dose of nitrogen (RDN) through a combination of 50% FYM and 50% poultry manure (O5) as basal dose recorded significantly higher fruit yield (16.33 t/ha) and yield components over other treatments. Among interactions, O5 (FYM (50%) + poultry manure (50%) recorded significantly higher fruit yield (18.47 t/ha), followed by 18.31 t/ha with organic application in O1 (FYM (50%) + Vermicompost (50%) in California Wonder variety

On the complete integrability of a nonlinear oscillator from group theoretical perspective

In this paper, we investigate the integrability aspects of a physically important nonlinear oscillator which lacks sufficient number of Lie point symmetries but can be integrated by quadrature. We explore the hidden symmetry, construct a second integral and derive the general solution of this oscillator by employing the recently introduced $\lambda$-symmetry approach and thereby establish the complete integrability of this nonlinear oscillator equation from a group theoretical perspective.Comment: 15 page

Molecular profiling of angiogenesis in hypericin mediated photodynamic therapy

<p>Abstract</p> <p>Background</p> <p>Photodynamic therapy (PDT) involves the administration of a tumor-localizing photosensitizing drug, which is activated by light of specific wavelength in the presence of molecular oxygen thus generating reactive oxygen species that is toxic to the tumor cells. PDT selectively destroys photosensitized tissue leading to various cellular and molecular responses. The present study was designed to examine the angiogenic responses at short (0.5 h) and long (6 h) drug light interval (DLI) hypericin-PDT (HY-PDT) treatment at 24 h and 30 days post treatment in a human bladder carcinoma xenograft model. As short DLI targets tumor vasculature and longer DLI induces greater cellular damage, we hypothesized a differential effect of these treatments on the expression of angiogenic factors.</p> <p>Results</p> <p>Immunohistochemistry (IHC) results showed minimal CD31 stained endothelium at 24 h post short DLI PDT indicating extensive vascular damage. Angiogenic proteins such as vascular endothelial growth factor (VEGF), tumor necrosis growth factor-α (TNF-α), interferon-α (IFN-α) and basic fibroblast growth factor (bFGF) were expressed to a greater extent in cellular targeting long DLI PDT compared to vascular mediated short DLI PDT. Gene expression profiling for angiogenesis pathway demonstrated downregulation of adhesion molecules – cadherin 5, collagen alpha 1 and 3 at 24 h post treatment. Hepatocyte growth factor (HGF) and Ephrin-A3 (EFNA3) were upregulated in all treatment groups suggesting a possible activation of c-Met and Ephrin-Eph signaling pathways.</p> <p>Conclusion</p> <p>In conclusion, long DLI HY-PDT induces upregulation of angiogenic proteins. Differential expression of genes involved in the angiogenesis pathway was observed in the various groups treated with HY-PDT.</p

Comparative effect of different sugars instigating non-enzymatic browning and Maillard reaction products in guava fruit leather

Browning is a major quality deterioration process affecting both visual colour and nutritional value of guava leather. The aim of the study was to determine the role of different sugars viz., sucrose, fructose, glucose and sorbitol in non-enzymatic browning and antioxidant activity of guava fruit leather. The total free amino acids, ascorbic acid and antioxidant activities were at significantly lower levels in glucose and fructose treated guava leather, while the sorbitol added samples had all of above parameters at the highest level; while a reverse trend was observed in browning index and non-enzymatic browning. Among the browning intermediate products, Hydroxymethylfurfural was present at higher concentration (12.80-32.32 ng/g) than furfural (0.29-0.95 ng/g) in guava leather samples. Among the treatments, hydroxymethylfurfural was found lowest in sorbitol (12.8 ng/g) and highest in fructose (32.3 ng/g). In brief, this paper describes a novel effort in bringing the in-vitro studies related to sugars and total free amino acids, influencing the biochemical and nutritional attributes which are responsible for browning in guava fruit leather
