Diversity of true mangroves and their associates in the Kundapura region, Udupi district, Karnataka, Southwest coast of India

The present study documents the diversity of true mangroves and their associates, in four selected sites of Kundapura, Udupi district, Karnataka, Southwest coast of India, for a period of two years from April-2010 to March-2012. These places are far from one another and the mangrove species diversity varies from one place to another, due to factors such as climate, tidal factors and anthropogenic pressures. Nine true mangrove floral species belonging to six families and ten associated floral species belonging to nine families were identified along the inundated and the adjacent regions at the study sites.  This write up discusses the need of present study is to gain knowledge about the mangrove flora in order help conservation of mangrove ecosystem

Study of the Dielectric Behaviour of Cr-Doped Zinc Nano Ferrites Synthesized by Sol-Gel Method

Abstract The series of Cr-Zn nano ferrites having the general composition Cr x ZnFe 2−x O 4 (0 ≤ x ≤ 0.5) have been synthesized successfully in the nanocrystalline form using the sol-gel method. The samples were sintered at 900˚C for 3 hours. The effect of chromium substitution on dielectric properties of Zn-ferrites is reported in this paper. The analysis of XRD patterns revealed the formation of single phase cubic spinel structure for all the Cr-Zn ferrite samples. The FTIR spectra show two strong absorption bands in the range of 400 -600 cm −1 , which corroborate the spinel structure of the samples. The average grain size was found to be in the nanometer range and of the order of 43 -63 nm obtained using TEM images. The lattice parameter and crystallite size decrease with increase in Cr concentration (x). The investigation on dielectric constant (ε'), dissipation factor (D) and ac conductivity (σ ac ) was carried out at a fixed frequency 1 kHz and in the frequency range of 100 Hz to 1 MHz at room temperature using LCR meter. The plots of dielectric constant (ε') versus frequency show the normal dielectric behavior of spinel ferrites. The value of ac conductivity (σ ac ) increases with increase in frequency for all the compositions. The appearance of the peak for each composition in the dissipation factor versus frequency curve suggests the presence of relaxing dipoles in the Cr-Zn nano ferrite samples. It is also found that the shifting of the relaxation peak towards lower frequency side with an increase in chromium content (x) is due to the strengthening of dipole-dipole interactions. The composition and frequency dependence of the dielectric constant, dielectric loss and ac-conductivity are explained based on the Koop's two-layer model, Maxwell-Wagner polarization process, and Debye relaxation theory. * Corresponding author.

MHD Free Convective Flow Past a Hot Vertical Porous Plate

The influence of the magnetic field on the free convective flow of a viscous fluid past a hot vertical porous plate is analysed under the assumptions that the suction velocity which is normal to the porous wall is constant and the wall temperature is spanwise cosinusoidal. The solutions for the velocity, temperature, skin friction and rate of heat transfer have been obtained in dimensionless form by perturbation technique. The effects of different flow parameters appearing in the solutions have been studied on the above flow quantities

IS MULLIGAN'S SUSTAINED NATURAL APOPHYSEAL GLIDES (SNAGS) OR MUSCLE ENERGY TECHNIQUE IS EFFECTIVE IN THE NON-SURGICAL MANAGEMENT OF CERVICOGENIC HEADACHE? A TWO-GROUP PRETEST-POSTTEST RANDOMIZED CONTROLLED TRIAL

Objective: The purpose of this study is to compare the efficacy of Mulligan's Glides like sustained natural apophyseal glides and muscle energy technique (MET) in the management of individual with cervicogenic headache (ICH).Methods: A total of 30 ICH were recruited by the simple random sampling to participate in this two-group pretest-posttest, single-blinded randomized clinical study. Recruited ICH was randomly allocated into two groups, Group A and Group B. ICH in Group A was provided with Mulligan's SNAGs of 3 glides/session/day×5 days/week×4-week duration, while in Group B, ICH received MET for suboccipital muscles for 6 times/session/day×5 days/ week×4 weeks. Both the groups received the common intervention of stretching and strengthening for cervical muscles for 4 weeks. Pain scores (visual analog score [VAS]), disability (headache disability index [HD]), and cervical extension range of motion (ROM) were documented at baseline and 4th week after intervention and analyzed.Results: Group B demonstrated significance difference (p<0.05) in HDI, VAS, and cervical extension ROM when compared to Group A.Conclusion: 4 week MET has the sufficient potential to decrease neck pain, disability, and increase cervical mobility among ICH as a non-surgical management

Fatty acid composition of serum and tissue lipids in male Indian desert gerbils (Meriones hurrianae; Jerdon) and Wistar rats

Serum lipids and fatty acid composition of total lipids, phospholipids and cholesterol ester fractions of serum, liver, heart and testes of male Indian desert gerbils (Marianas hurrianae; Jerdon) were analysed and compared with Wistar rats.Triglycerides in serum and liver were similar in gerbils and rats, Significant differences in the distribution of polyunsaturated fatty acids in different lipid fractions were observed between gerbils and rats. Total lipids, phospholipids and cholesterol  ester fractions in rats contained higher levels of arachidonic acid than in gerbils

Volume Integral Theorem for Exotic Matter

We answer an important question in general relativity about the volume integral theorem for exotic matter by suggesting an exact integral quantifier for matter violating Averaged Null Energy Condition (ANEC). It is checked against some well known static, spherically symmetric traversable wormhole solutions of general relativity with a sign reversed kinetic term minimally coupled scalar field. The improved quantifier is consistent with the principle that traversable wormholes can be supported by arbitrarily small quantities of exotic matter.Comment: 7 page

SUPPLEMENTATION OF Α-LIPOIC ACID IN DIABETIC PERIPHERAL NEUROPATHY: A PROSPECTIVE OPEN LABEL RANDOMIZED CONTROLLED TRIAL

Abstract Objective: Diabetic peripheral neuropathy is the most common long term complications associated with reduced nerve conduction and blood flow. The present study was designed to investigate the effect of oral supplementation of α-lipoic acid (600 mg/day) on peripheral, sensory and motor nerve conduction and glycaemic control in type 2 diabetes mellitus with peripheral neuropathy. Methods: A total of 20 patients were enrolled in this study, then randomly allocated to two groups control (n=10) and intervention group (n=10). Patients in control group received only oral hypoglycaemic treatment and in intervention group received α-lipoic acid (600 mg/day) oral supplementation along with their oral hypoglycaemic treatment for a period of 3 months. Nerve conduction and glycaemic control were measured at the base line and at the end of 3 months by using specific methods. Results: In intervention group α-lipoic acid supplementation significantly improves 6 of 15 electrophysiological parameters of nerve conduction. Distal latency of peroneal (mean ± SD 5.13 ± 0.52 vs 4.92±0.55; p<0.02), median (mean ± SD 3.66 ± 0.76 vs 3.53±0.63; p<0.03) & ulnar motor nerves (mean ± SD 2.91 ± 0.32 vs 2.82±0.36; p<0.01), and Nerve Conduction Velocity of peroneal (mean ± SD 42.0 ± 3.07 vs 43.4±2.13; p<0.03), median (mean ± SD 51.4 ± 3.31 vs 52.2±3.59; p<0.01) & ulnar motor nerves (mean ± SD 51.0 ± 5.84 vs 52.1±5.46; p<0.03) shows significant improvement. Conclusion: Oral supplementation of α-lipoic acid was found to be effective in improving motor nerve conduction of upper and lower extremities in patients with diabetic peripheral neuropathy

Development of a high resolution land surface dataset for the South Asian monsoon region

In this study, we report the development of a high resolution land surface dataset for the South Asian monsoon region for studies on land surface processes, and land and atmosphere coupling. The high resolu- tion land data assimilation system was used to develop the land surface dataset utilizing TRMM rainfall and ECMWF atmospheric variables as forcing parameters. The dataset was developed at a spatial resolution of 0.5° and temporal resolution of 1 h and spans a period of 6 years, i.e. 1 January 2005 to 31 December 2010. The major highlights in the development of the present dataset are higher spatial and temporal resolution of land surface parameters, use of sub-daily forcing parameters including rainfall, use of MODIS land-use data in lieu of USGS land-use data and weekly varying vegetation fraction instead of monthly vegetation climatology. A comparison of soil moisture and soil temperature with limited surface observations of the IMD suggests reasonable reliability of the land surface data. The model sensible heat flux data are compared with in situ measurements at Ranchi and MEERA reanalysis data. The sensitivity analysis shows that the land surface data are sensitive to rainfall and green vegetation cover data used as the forcing parameters. The dataset has been used to discuss the variations of land surface processes associated with active and break spells and a severe heat wave observed in 2009. The present dataset will be useful for many applications, including initializing numerical models for weather prediction. This high resolution land surface dataset is available for research on request
