    Abstract The historical 1 September 1803 Garhwal–Kumaon Himalaya earthquake (Mw 8.1) was a solitary Himalayan earthquake reported felt widely in the Indo-Gangetic Plain with severe shaking observed from Punjab to Bengal. There was no common consensus among 9 different researchers on the source location and size of the Pre-instrumented 1 September 1803 earthquake. In this study, we attempted to resolve the issues based on source, path, and site characterization by estimating peak ground accelerations (PGAs) and correlation between estimated and reported intensities based on the concept of strong motion seismology. In order to arrive at a plausible epicenter location of the pre-instrumented 1803 earthquake, we conducted a detailed postmortem, for the first time of its all of 9-different source locations propounded by different researchers and examined those locations based on the nature and extent of damage pattern; extent of earthquake shaking; intensity at source rock; source characterization; path characterization; and estimates of peak ground acceleration (PGA) at different earthquake hypocenters. In order to achieve a better correlation, the hypocentre is considered at 11 locations at MHT from Higher Himalaya to Sub Himalaya. The surface PGA and MMI are estimated at all locations where the intensity was reported for the 1803 earthquake by considering about 100 scenario earthquakes. Out of nine locations proposed by previous researchers, the five locations fall in the highest and one in the higher seismic attenuation zone that negates the nature and extent of earthquake shaking up to the distance of more than 1200 km at Kolkata then Calcutta where the intensity was reported to be IV. The other locations propsed in least atteuation zone were of less magnitude. We, therefore infer that the 1803 earthquake occurred at the depth of 20 km located in the least seismic attenuation zone in the NW Himalaya with a location of 31.2ᵒN, 78.7°E (130 km north of the HFT, 50 km north of the 1991 Uttarkashi earthquake) with a rupture dimension of 190 × 81 Sq. km with a slip of 3.0 m that corresponds to a magnitude of Mw 8.1. We also inferred that the mainshock rupture was directed toward the south along the Main Himalayan Thrust and the rupture found stopped at 50 km north of the HFT below the Ton Thrust in the Lesser Himalaya. This study also confirms that the rupture of the 1803 Garhwal–Kumaon earthquake has not reached up to the HFT. The 1991 Uttarkashi and 1999 Chamoli earthquakes are inferred to be located at the southern end of the 1803 Garhwal Kumaon earthquake rupture area. A slip deficiency of 1.3 m has been computed with reference to the source zones of the 1803 Garhwal–Kumaon, 1991 Uttarkashi, and 1999 Chamoli earthquakes, suggesting a maximum magnitude potential of Mw 7.2 The Tehri Dam is located approximately 20 km south of the 1991 Uttarkashi earthquake source zone and is believed to lie outside the rupture zone of the 1803 Garhwal–Kumaon earthquake.

    Abstract Knowledge is one of the most vital inputs for development because everything we do depends upon knowledge. Keeping the importance in assessing knowledge of clietele in the field of Extension Education, an attempt has been made to build up a knowledge test for measuring knowledge level of maize growers about improved maize production technology in Saharsa district of Bihar state. Maize (Zeamays) is one of the most important cereal crops in the world grown over in area of 132 m.ha. with a production of 570 mt. It is the crop with the highest per day productivity. In India, maize is next in important crop after rice and has acreage around 6 m.ha with a production of 10.5m.t. Maize is the third most important cereal crop of the country after rice and wheat. Maize is a non-tiller plant. It is valued as food, feed, fodder and industrial raw material. In view of maize being produced under very diverse ecology in our country, development of high yielding hybrids with in-built resistance and tolerance to diseases, pests and various climatic stresses; and development and fine-tuning of production ecology are our top priorities. During last 10 years, more than 120 hybrids have been developed and released in addition to development of various production technologies. Classification of maize on the basis of endosperm characteristics. It is classified in to seven groups. They are Dent corn, Flint corn, Sweet corn, Flour corn, Popcorn, Waxy corn, and Pod corn. The developed knowledge test was administered to the selected 220 respondents selected for the study. With the using of this test it was found that majority of the respondents had medium level of knowledge (52.27%) followed by low (28.18%) and high (19.55%) about improved maize production Technology.

    Abstract Idiopathic nephrotic syndrome is one of the most common chronic renal disorders in children. Associated bilateral pleural effusion is common due to the transudative process as a result of hypoalbuminemia. However, unilateral pleural effusion is a rare phenomenon and at times, unresponsive even when the patients are in remission. Here, we report two cases of frequent relapse nephrotic syndrome presented as persistent unilateral pleural effusion responsive to chemical pleurodesis, which was done with bleomycin along with normal saline.

    Abstract Our detailed 3-D seismic tomographic assimilation using high-quality phase arrival time data recorded by the local seismographic network demonstrated that heterogeneities in the crustal faults have contributed significantly to the pop-up tectonics beneath the Shillong Plateau, characterized by high-V and low-σ. The major seismogenic faults, namely, the north-dipping Dapsi thrust in association with Dauki fault in the south and south dipping Brahmaputra fault in the north, located either side of the Shillong Plateau that acted as the causative factors for the pop-up, which attributed to the lithostatic (high-V, low-σ) and sedimentary (low-V, high-σ) load, respectively. Seismicity is found confined to a depth ≤ 60 km. Uneven distribution of structural heterogeneities in the upper crust is responsible for earthquake genesis of varying strengths. It is intriguing to note that high-velocity anomalies and low-ϭ in the uppermost crust, interpreted as the Shillong Plateau that acted as a geometric asperity and the juxtaposition of high-V and low-V became the source zone of the 1897 Shillong earthquake (M

    Abstract This research aimed to investigate the efficiency of crude xylanase-pectinase in pulping of sugarcane bagasse. Optimum biopulping was obtained, using xylanase-pectinase dose 200-60 IU/g, bagasse/liquid ratio 1:10 and 1.0% Tween 80 concentration at 55 °C temperature, pH 8.5 and period of treatment 180 min. Treatment of sugarcane bagasse samples with these enzymes generated pulp with lower rejections (58.76%), total solids (12.64%), kappa number (47.77%), higher screened pulp yield (10.66%), along with enhanced optical and physical properties, in comparison with a chemical pulp. Bagasse biopulping resulted in a 13% decrease in alkali dose to obtain the optical and physical properties similar to those achieved under the 100% alkali dose. The breaking length, burst factor, tear index, double fold, gurley porosity and viscosity were improved by 15.19, 37.64, 2.47, 37.77, 35 and 23.17%, respectively, after bleaching treatment of biopulped samples. Thus, enzymatic pulping is an eco-friendly environmentally sustainable approach, since it reduces the use of pulping chemicals and simultaneously improves the paper quality. This is the first report, showing pulping of sugarcane bagasse, with crude xylanase-pectinase, produced by an isolate.

    Abstract Diabetes mellitus is a complex chronic condition that results in hyperglycemic environment affecting the metabolism of proteins and lipids, promotes inflammation and delays wound healing. A total of n=30 Wistar rats of either sex were divided into five groups with 6 animals in each. Diabetes mellitus was induced using streptozotocin @ 35 mg/kg body weight and excision wound model was developed in all the animals. Group I and Group II were considered as healthy and diabetic control group respectively. The wounds of Group III, IV and V were treated with topical application of Carica papaya synthesized silver nanoparticles @ 62.5 |jg/ml, Carica papaya leafextract @ 31.25 mg/ml and 10% povidone iodine respectively. Present study concluded that the characteristics of silver nanaoparticles synthesized form C. papaya leaf extract make them suitable for the treatment of wound healing in diabetic subjects.

    Abstract The emergence and spread of antimicrobial resistance have become a major global public health concern. A component of this problem is the spread of antibiotic‐resistant bacteria. Flies move freely between habitats of food‐producing animals and human beings and thus have great potential for dissemination of antimicrobial‐resistant bacteria from a contaminated environment to milk and meat markets, posing potential hazards for consumers. During the present study, a total of 150 houseflies were captured from milk and meat shops located in Durg and Raipur city of Chhattisgarh, India. The Escherichia coli were isolated from houseflies and characterized on the basis of cultural and molecular tests. Further, the isolates were subjected to antimicrobial susceptibility testing against frequently used antibiotics using the disk diffusion method. The antibiotic resistance genes and int1 gene were detected using polymerase chain reaction (PCR). A total of 45 E. coli isolates were obtained from the fly samples with an overall prevalence rate of 30·0%. Antibiogram results confirmed that E. coli isolates were resistant to multiple antibiotics. Out of the (45) isolates of E. coli, 17 (37·8%) isolates were extended‐spectrum beta‐lactamase (ESBL) producer and multi‐drug‐resistant (MDR). Out of the ESBL and MDR E. coli isolates, blaCTX‐M (24·4%), blaTEM (11·1%), tetA (28·8%), tetB (26·7%), gyrA (26·7%), parC (31. 1%) and int1 genes (15·5%) were detected but none of the isolates were found positive for blaSHV gene. Findings of the present study confirm that MDR E. coli are widely distributed in houseflies and play an important role in the transmission of antibiotic‐resistant bacteria from contaminated environments to milk and meat shop environment.

    Abstract A magnetotelluric (MT) geophysical survey for the first time has been conducted for the geoelectric characterization of the junction of the contact zone of NNE-SSW striking Delhi Hardwar Ridge (DHR) and NW-SE trending Delhi Sargodha Ridge (DSR) in the Rohtak area, Haryana which has experienced 15 earthquakes of M2.0-M4.4 from April to August 2020. A total of 08 MT sites are acquired along a NW-SE profile of length 50 km. From the 2D MT data inversion, the DHR and DSR are for the first time characterized by equal values of moderate resistivity of 100 Ohm m at two depths. The resistivity variation for DHR corresponds to 100 Ohm m from the surface to the depth of 20 km, whilst DSR is found associated with the same value of resistivity extending in the NW direction. The DHR has been found striking NE-SW with a very shallow central axis (less than 400 m) having a width of 12-15 km forming half grabens on both limbs supported by shallow faults. The DSR has been found bifurcated from DHR at a depth of 12-13 km and extended in the NW direction. The DSR has been generated due to flexure bulging caused by collision and anticlockwise rotation of the Indian plate in the Eocene period. A NE striking steep dipping reverse fault (F1) has also been identified about 15 km west of the DHR. It is inferred that the DSR got upthrusted along this fault and became shallower in the NW region. The seismicity in the Rohtak and surroundings is located at the bifurcation points of DHR and DSR and the contact zone of DSR and reverse fault F1. The reverse fault F1 is also active and has generated microseismicity in the past.
