Abstract
Purpose The main purpose of this study is to highlight the involvement of the facial nerve as one of the presenting symptoms in patients suspected of coronavirus disease associated mucormycosis (CAM). Methods This is a retrospective observational study conducted at a tertiary care referral centre which included 300 patients with past history of being treated for coronavirus disease and who presented to our department with symptoms of invasive fungal sinusitis. All the patients were evaluated clinically and radiologically for presence of facial nerve palsy (FNP) in suspected cases of CAM. All the patients were managed with combined modality treatment with antifungal therapy and radical endoscopic debridement of the necrotic tissue and fungal debris. Results The data were analysed to assess the possible epidemiological factors linked to CAM. Diabetes mellitus was the most common associated factor identified for aggravating of CAM. FNP is also one of the common presentation seen among 53 patients with CAM. Conclusion FNP is an unusual but significant sign in presentation of mucormycosis. It could be easily misdiagnosed as cerebrovascular accident leading to delay in the treatment. During this era of Covid-19 pandemic where wearing of masks has become mandatory, there is a high probability of this finding to be missed. Thus, our study emphasises for thorough cranial nerve examination in all cases of CAM, for an early and an immediate intervention to prevent the spread of the disease and also to improve the overall general condition of the patient.

Abstract
The present study aims at analysis of spatial and temporal variability in agricultural land cover during 2005-6 and 2011-12 from an ongoing program of annual land use mapping using multidate Advanced Wide Field Sensor (AWiFS) data aboard Resourcesat-1 and 2. About 640-690 multi-temporal AWiFS quadrant data products per year (depending on cloud cover) were co-registered and radiometrically normalized to prepare state (administrative unit) mosaics. An 18-fold classification was adopted in this project. Rule-based techniques along with maximum-likelihood algorithm were employed to deriving land cover information as well as changes within agricultural land cover classes. The agricultural land cover classes include - kharif (June-October), rabi (November-April), zaid (April-June), area sown more than once, fallow lands and plantation crops. Mean kappa accuracy of these estimates varied from 0.87 to 0.96 for various classes. Standard error of estimate has been computed for each class annually and the area estimates were corrected using standard error of estimate. The corrected estimates range between 99 and 116 Mha for kharif and 77-91 Mha for rabi. The kharif, rabi and net sown area were aggregated at 10 km × 10 km grid on annual basis for entire India and CV was computed at each grid cell using temporal spatially-aggregated area as input. This spatial variability of agricultural land cover classes was analyzed across meteorological zones, irrigated command areas and administrative boundaries. The results indicate that out of various states/meteorological zones, Punjab was consistently cropped during kharif as well as rabi seasons. Out of all irrigated commands, Tawa irrigated command was consistently cropped during rabi season.

Abstract
We report our 10-year experience with penile injuries. We retrospectively reviewed the records of 156 cases of male external genitalia injuries between May 2002 and December 2012. Of these, only 26 patients presented without urethral injuries and were included in this study. Patients were divided into 4 groups: Group 1 (n = 12) with patients with penile fractures injuries; Group 2 (n = 5) with patients with penile amputation injuries; Group 3 (n = 2) with patients with penile penetrating injuries; and Group 4 (n = 7) with patients with penile soft tissue injuries. Grading of injury was done using the American Association for the Surgery of Trauma (AAST)-Organ injury scale of penile injury. Penile injuries without urethral injuries are urological emergencies which require immediate attention.

Abstract
Imposition of large amplitude oscillatory shear (LAOS) on crystallizing polymer melts results in lamellar orientation in the shear gradient direction, in contrast to the flow-orientation observed for steady shear. LAOS enhances the formation of plate-like nuclei and orients their normals in the gradient direction. An Arrhenius temperature dependence (with activation energy ≈ 226 kJ/mol) characterizes the relaxation of crystal orientation with annealing.

Abstract
ABSTRACTSmall signal dielectric response is reported for a variety of PZT thin film samples. Small and large signal responses, recorded simultaneously during the fatiguing of PZT thin films, are used to identify distinct fatigue mechanisms. Microcracking or electrode delamination less than 100 Å is sufficient to explain the high correlation between the dielectric permittivity and remanent polarization during fatigue.

Abstract
OBJECTIVES AND METHODS DRF 8417, a novel oxazolidinone, has been evaluated against Gram-positive and fastidious Gram-negative bacteria. In vitro activity of DRF 8417 was determined by broth microdilution method and in vivo efficacy studies were carried out in different murine systemic infection models. RESULTS DRF 8417 exhibited potent activity against Gram-positive pathogens with MIC(50) and MIC(90) values ranging from 0.06 to 1 mg/L. MICs against Haemophilus influenzae and Moraxella catarrhalis were one to two dilutions lower than those of linezolid. The in vivo efficacy, by oral route, in different susceptible and resistant Gram-positive systemic bacterial infection models ranged from 2.0 to 2.9 mg/kg. CONCLUSIONS These studies displayed the excellent in vitro and in vivo activity of DRF 8417 against Gram-positive pathogens and lower MICs when compared with linezolid against H. influenzae and M. catarrhalis.

Abstract
We report here the first observation of the low frequency Raman scattering from acoustic phonons in semiconducting zinc oxide (ZnO) nanoparticles without embedding in any solid matrix. ZnO nanoparticles (size 5-10 nm) with nearly spherical shape have been synthesized using a chemical route. A shift in the phonon peaks toward higher frequencies along with broadening was observed with a decrease in particle size. The size dependence of the acoustic phonons in ZnO nanoparticles is explained using Lamb's theory that predicts the vibrational frequencies of a homogeneous elastic body of spherical shape. Our results show that the observed low frequency Raman scattering originates from the spherical (l = 0) and quadrupolar vibrations (l = 2) of the spheroidal mode due to the confinement of acoustic vibrations in ZnO nanoparticles.

Abstract
The structural and dielectric properties of sol-gel derived barium-strontium-titanate (Ba(0.4)Sr(0.6)TiO(3 )) thin films have been investigated. The as-fired films are found to be amorphous, and films crystallize to a cubic phase after a post deposition annealing at 700 degrees C for one hour in air. The variation of dielectric constant with temperature and field was investigated as a function of film thickness. These films display a nonlinear dielectric response that can be described in terms of a power series expansion of the free energy in polarization as in Landau-Ginzburg-Devonshire approach. The measured room temperature dielectric constant (epsilon') of the film was about 320. The dielectric constant did not show any significant frequency dependence up to 100 kHz. The temperature dependence of dielectric constant exhibited a diffused ferroelectric to paraelectric phase transition at -60 degrees C. The room temperature dielectric constant and magnitude of the dielectric peak at the Curie point was dependent on the thickness of the film. The obtained dielectric data on sol-gel barium strontium titanate thin films on platinized substrates were analyzed in the light of a barrier layer model.

Abstract
We have characterized a DNA binding protein (DBNP-B) from the thermoacidophilic archaeon Sulfolobus acidocaldarius with respect to its interaction with single and double stranded DNA. The protein in solution exists predominantly as dimer as indicated by cross linking studies. Binding of DBNP-B to etheno DNA and poly (dA) resulted in fluorescence enhancement and hyperchromicity respectively. Ethidium bromide intercalated into DNA was completely displaced by DBNP-B. DNase I digestion of dsDNA was increased at subsaturating concentration of the protein and was inhibited at higher concentrations. These results and electron microscopy indicate that the protein forms different types of novel complexes with DNA at different protein to DNA ratios.

Abstract
A lectin specific for alpha-methyl-D-mannoside was purified from the membrane extract of Giardia lamblia by a combination of gel filtration chromatography on Sephadex G-75 and Superose 6-HR 10/30. The homogeneity of the lectin was established by sodium dodecyl sulfate polyacrylamide gel electrophoresis. The molecular mass of the native protein was 148 kDa. The lectin agglutinated rabbit erythrocytes in the presence of Ca2+ at 37 degrees C and pH 7.0. The maximum activity of the lectin was obtained after trypsin treatment. The inhibition study clearly suggests that the binding site of the lectin recognizes alpha-methyl-D-mannoside as the immunodominant sugar.

Abstract
A fractionation method involving precipitation of proteins with novobiocin has been developed to separate ribosomal proteins of the archaebacterium Sulfolobus acidocaldarius. Four groups of proteins were obtained corresponding to those precipitated with 0.2, 0.5 and 1.0 mg/ml novobiocin and the proteins soluble at 1.0 mg/ml novobiocin. The same procedure was also successful for the fractionation of ribosomal proteins from Escherichia coli. Two dimensional gel electrophoresis showed that proteins present in each group were distinct with only a minor contamination of proteins from other groups. Our results indicate that proteins with similar charge and molecular weight can be separated by this method. This procedure may have applications for the fractionation of other complex protein mixtures.
