Complementary nature of surface and atmospheric parameters associated with Haiti earthquake of 12 January 2010

The present paper describes surface (surface air temperature) and atmospheric parameters (relative humidity, surface latent heat flux) over the epicenter (18°27´25´´ N 72°31´59´´ W) of Haiti earthquake of 12 January 2010. Our analysis shows pronounced changes in surface and atmospheric parameters few days prior to the main earthquake event. Changes in relative humidity are found from the surface up to an altitude of 500 hPa clearly show atmospheric perturbations associated with the earthquake event. The purpose of this paper is to show complementary nature of the changes observed in surface, atmospheric and meteorological parameters. The total ozone concentration is found to be lowest on the day of earthquake and afterwards found to be increased within a week of earthquake. The present results show existence of coupling between lithosphere-atmosphere associated with the deadly Haiti earthquake

Dynamical Characteristics of Atmospheric Aerosols over IG Region

The dynamical characteristics of atmospheric aerosols over the Indo-Gangetic (IG) region are primarily dependent on the geographical settings and meteorological conditions. Detailed analysis of multi satellite data and ground observations have been carried out over three different cities i.e. Kanpur, Greater Noida and Amritsar during 2010-2013. Level-3 Moderate Resolution Imaging Spectroradiometer (MODIS) terra daily global grid product with spatial resolution of 1° × 1° shows the mean AOD at 500 nm wavelength value of 0.73, 0.70 and 0.67 with the standard deviation of 0.43, 0.39 and 0.36 respectively over Amritsar, Greater Noida and Kanpur. Our detailed analysis shows characteristic behavior of aerosols from west to east in the IG region depending upon the proximity of desert regions of Arabia. We have observed large influx of dusts from the Thar desert and Arabia peninsula during pre-monsoon season (April–June), highly affecting Amritsar which is close to the desert region

Seasonal Variability of Atmospheric Aerosol Parameters over Greater Noida Using Ground Sunphotometer Observations

Atmospheric aerosols over northern India are subject of significant temporal and spatial variability and many studies have been carried out to investigate their physico-chemical and optical properties. The present work emphasizes on examining the aerosol optical properties and types over Greater Noida, Delhi region, using ground-based sun photometer data during the period 2010–2012. The analysis reveals a relatively high mean aerosol optical depth at 500 nm (AOD 500 = 0.82 ± 0.39), associated with a moderate Angstrom exponent α 440–870 of 0.95 ± 0.37. Both parameters, exhibit significant daily, monthly and seasonal variability with higher values of AOD 500 during post-monsoon (0.98 ± 0.50) and winter (0.87 ± 0.35) seasons associated with high α values (\u3e 1.1) suggesting significant urban and biomass-burning contribution. On monthly basis, the highest AOD is found during July and November and the lowest one in the transition months of March and September. The aero ol-type discrimination vi a the relationship AOD vs. α shows a clear dominance of urban/industrial and biomass-burning aerosols during post-monsoon and winter in fractions of 74.5% and 72%, respectively, while aerosols of desert-dust characteristics were most frequent in pre-monsoon (41.7%) and monsoon (21%) seasons. In general, the analysis shows a rather well-mixed aerosol type under very turbid atmosphere, which is associated with the long range transport of pollutants through the westerly winds from the Thar desert and biomass burning in the western parts of India

A CLINICAL EVALUATION OF ANTIMICROBIAL ACTIVITY OF GOMUTRA ARKA IN DUSTA VRANA

Vrana chikitsha is very significant in field of Shalya tantra. Healing of Vrana is depends on many factors. Among them growth of microorganism play essential role to slow the process of healing. In Dusta Vrana to improve the healthy granulation and to reduce the colony count of microorganism specific Krimghna dravya is required for that in Shasthi upkrama under Krimighna karma Gomutra Arka is advised. Which has additional property of Lekhana and Ropana. Gomutra Arka is given importance in many oral classical formulation of Ayurveda to treat the Krimi, which is not evaluated for local application on Dusta Vrana yet. Materials and Methods: A simple randomized controlled clinical study where 50 patients were equally divided as group A: Gomutra Arka (trial drug) and Group B: Povidone-iodine (standard drug) for 14 days. Observations and results: The study result revealed that Gomutra Arka proved to be better Antimicrobial agents than povidone-iodine with a highly significant p-value of 0.04 in comparison to 0.68. It was also established in the study that 10mlGomutra Arka proved to be more effective on different microorganisms that are Staphylococcus Aureus, Pseudomonas Aeruginosa, Shigella, Salmonella, E. Coli, and Candida Albicans. Conclusion: The Gomutra Arka acts as an antimicrobial agent due to its property like Katu tikta kashya rasa which are Krimighna in nature by this inhibition of microorganism could happen also due to the Ushna tikshna and Kshara guna gives unfavorable environment for bacterial growth. The presence of constituents like copper, aurum, urea, ammonia further helps in antimicrobial activity. Therefore, Gomutra Arka can be used in regular practice as its available at a low cost, affordable and the study proves its efficiency over the Povidone-iodine controlled group

Evaluation of clinical results and complications of internal fixation of intertrochanteric femur fracture with proximal femoral nail antirotation

Background: The purpose of the present study was to evaluate the theoretical advantages of the proximal femoral nail antirotation in cases of intertrochanteric fractures and also whether it actually alters the eventual functional outcome of the patient.Methods: The present study includes a total 30 patients with intertrochanteric femur fractures managed with proximal femoral nail antirotation between December 2014 to November 2016. In all patients similar standard physical rehabilitation therapy were followed. All complications including intra and postoperative were assessed and recorded. The patients were followed up for over 24 months. Functional outcome was assessed using the Harris hip score.Results: All of 30 cases of intertrochanteric fracture got united with good anatomical position and average time of fracture union was 14 weeks. Postoperative complications included 2 degree varus deformity (n=1, 3%), calcification at tip of greater trochanter (n=4, 13%), sensitivity over TFL (n=2, 7%), medial thigh pain (n=3, 10%). 10 patients developed femoral shortness (mean=0.22 cm, range from 0-1 cm). Average harris hip score at the end of study showed mean value of 87, ranged from 65 to 94 with almost 22 (73%) patients showing excellent or good outcome.Conclusions: Proximal femoral nail antirotation (PFNA) represents a significant treatment option in management of intertrochanteric fractures with low complication rate

Evaluation of Antioxidant Capacities and Total Polyphenols in Various Edible Parts of Capparis spinosa L. Collected from Trans-Himalayas

The phytochemical screening, antioxidant capacity, and total polyphenols in the methanolic extract of leaves, flower buds, roots and fruits of Capparis spinosa collected from trans-Himalayan region of Ladakh were assessed in an effort to corroborate its medicinal and culinary potential. Highest DPPH and ABTS radical scavenging activity were observed in the leaves and least in dried fruit samples, even FRAP assay also illustrated the same trend. IC50 values of DPPH assay was highly correlated with that of ABTS (R2=0.9084) and FRAP assay (R2=0.9771). However, IC50 value of ABTS was reasonably correlated with FRAP assay (R2=0.5838). The highest phenolic and flavonoid content was recorded in the leaf samples (24.78 and 5.69 mg GAE/g DW respectively), whereas it was lowest in the dried fruit samples (4.07 mg quercetin equivalent/g DW and nil, respectively). The total phenolic contents were highly correlated with IC50 value of ABTS (R2=0.9084), DPPH (R2=0.9388) and FRAP value (R2=0.9618). But, total flavonoid contents were highly correlated with ABTS (R2=0.7449), DPPH (R2=0.8791) and FRAP values (R2=0.9588). Thus, this study has validated the medicinal potential of all the edible parts of the C. spinosa

Estimation of NOx Emissions from Delhi Using Car MAX-DOAS Observations and Comparison with OMI Satellite Data

We present the first Multi-Axis-(MAX-) DOAS observations in India performed during April 2010 and January 2011 in Delhi and nearby regions. The MAX-DOAS instrument was mounted on a car roof, which allowed us to perform measurements along individual driving routes. From car MAX-DOAS observations along closed circles around Delhi, together with information on wind speed and direction, the NOx emissions from the greater Delhi area were determined: our estimate of 4.4 x 10(25) molecules s(-1) is found to be slightly lower than the corresponding emission estimates using the EDGAR emission inventory and substantially smaller compared to a recent study by Gurjar et al. (2004). We also determined NOx emissions from Delhi using OMI satellite observations on the same days. These emissions are slightly smaller than those from the car MAX-DOAS measurements. Finally the car MAX-DOAS observations were also used for the validation of simultaneous OMI satellite measurements of the tropospheric NO2 VCD and found a good agreement of the spatial patterns. Concerning the absolute values, OMI data are, on average, higher than the car MAX-DOAS observations close to strong emission sources, and vice versa over less polluted regions. Our results indicate that OMI NO2 VCDs are biased low over strongly polluted regions, probably caused by inadequate a-priori profiles used in the OMI satellite retrieval
