The usage of gold and the investment analysis based on gold rate in India

Gold is one of the main commodities where the customers invest their money comparatively with bank for better interest. In the Indian context people purchase gold for their children’s marriages for later period. The investment in gold is better suits for easy conversion into money with quickest possible time from the bank and gold merchants. The appreciation or depreciation of gold based on other investment options like fixed deposit, provident fund, international crude oil price, stock market, mutual fund etc. The comparative analysis of gold with other investment options give an edge to the customer to clearly understand the investment pattern for their hard-earned money expected to give good returns in the future

Exploitation of Acoustic signature of Low flying Aircraft using Acoustic Vector Sensor

Acoustics is emerging as a significant complementary modality to be explored and exploited in the development of Intelligence and surveillance systems that traditionally rely on technology rooted in electro-magnetic field phenomena. Acoustics is emerging as a significant complementary modality to be explored and exploited in the development of Intelligence and surveillance systems that traditionally rely on technology rooted in electro-magnetic field phenomena. An application of the current interest is the detection and localization of the sound sources on battlefield using Acoustic sensors in ground and on board unmanned aerial vehicle. In this work a nonlinear least-square cepstrum and auto correlation methods are made to estimate the motion parameters of a low flying aircraft whose narrowband acoustic energy emissions were received by a ground-based Acoustic vector sensor. The data obtained from the sensor were processed and analyzed using digital signal processing approach. This passive technique is applied to real acoustic sensor data under the condition that the vehicle flies at a constant velocity and the trajectory is a straight line. The performances of both methods are evaluated and compared using actual acoustic data.Defence Science Journal, 2014, 64(2), pp. 95-98. DOI: http://dx.doi.org/10.14429/dsj.64.3924

Biosorption of chromium by mangrove-derived Aplanochytrium sp.

The microbial dried biomass of Thraustochytrids is used as bioadsorbent for the removal of the chromium in aqueous solution. In this investigation, three species of Thraustochydrids namely Aplanochytrium sp., Thraustochytrium sp. and Schizochytrium sp. were tested for the efficiency of chromium accumulation by culturing in chromium-incorporated medium at 30°C for one week incubation. The biomass was harvested by filtration through Whatman no.1 filter paper. The level of metal accumulation in the biomass was determined by using an inductively coupled plasma system (ICP- Optical Emission Spectrophotometer; Optima 2100DV). Finally, among the three strains, Aplanochytrium spp. was selected for the adsorption kinetics and optimization using response surface methodology. Optimization of chromium removal by dried microbial biomass was analyzed with important factors of different pH, adsorbent dosage (Aplanochytrium dried biomass), temperature and processing time with 30 batch experimental plan derived from the centre composite design (CCD) of response surface methodology. Aplanochytrium sp. dried biomass removed chromium of 69.4% in aqueous solution. Therefore, Aplanochytrium sp. dried biomass is potent for the removal of chromium in waste water treatment.Key words: Mangroves, chromium removal, Aplanochytrium sp., biosorption, waste water treatment

Bio-ethanol production by marine yeasts isolated from coastal mangrove sediment

This study analyzed ethanol production by 10 marine strains of yeasts, isolated from mangrove sediments. Of the species tested, Pichia salcaria exhibited the maximum ethanol production of 12.3±3.1 g/l. This was further studied in the culture filtrate supplemented with different concentrations (0.01, 0.1, 1, 2 and 4% w/v) of sawdust as substrate that was pre-processed with phosphoric acid, and then incubated for different durations (24,48,72, 96 and 120 h). The ethanol production by P. salcaria was found maximum (26.2±8.9 g/l) in 72 hours of fermentation in the culture broth supplemented with 2% sawdust that was preprocessed with dilute phosphoric acid. This condition of fermentation was found coincided with high activity cell ase in the cul ure broth, which also revealed a single prominent protein band of 68 kDa molecular weight, similar to cellulase. The study proved the efficiency of marine P. salcaria in bioethanol production

A study on functional and radiological outcome of complex tibial plateau fractures by posteromedial plating

Background: In orthopaedic practice, three column concept and fixation for proximal tibia are becoming popular as it was proved that fixation of posterior column is a must for proper weight transmission and stability. This study demonstrates the use of the posteromedial surgical approach to the knee in treating patients with complex tibial plateau injuries with a posteromedial column fracture. The aim of the study was to study the functional and radiological outcome of complex tibial plateau fracture by posteromedial plating.Methods: This is a prospective study involving 20 patients with complex tibial condyle fractures with posterior column fractures. Preoperative computed tomography is taken with radiography for complete evaluation of fracture fragments even in the coronal plane. Fractures were classified as Schatzker type 4 or above with a posteromedial split depression. Plating is done with posteromedial locking compression for buttressing posteromedial fragment. The outcome of surgery was evaluated using the Oxford knee scoring system. Longest follow up of study is 2 years.Results: All fractures healed within 6 months without any secondary displacements or secondary osteoarthritis. Out of 20 patients 16 patients have the postoperative anatomic reduction (0 mm step off) 2 had an acceptable reduction of <2 mm step off. At 4-12 months median range of flexion 135*(125-145*). The mean Oxford knee score was 25-33.Conclusions: Fixation of posteromedial fragment in a complex tibial condyle fracture is a must as it involves posterior column. Using a locking compression plate provides perfect fracture fixation and thereby more stability to knee joint & better functional outcome

In vitro micropropagation of Musa sapientum L. (Cavendish Dwarf)

A complete protocol for micropropagation of Musa sapientum using shoot meristems was developed. Multiple shoots were induced in vitro from shoot meristems. Murashige and Skoog’s medium supplemented with BAP and NAA (3.0 + 0.2 mg/l, respectively) was found to be most suitablecombination. Further multiplication of shoots required habituation of cultures up to 3 passages of 21 days each on the same medium after establishment of culture and initiation of shoot buds. Thereafter 3-fold multiplication rate was achieved during every subculture. For rooting the shoots were excised and transferred to same medium. Rooted plantlets were then transferred to primary and secondary hardening and grown in the green house. These hardened plants have been successfully established insoil

Comparison of Clinical and Radiographic Success of Three Obturation Materials in Primary Teeth: A Randomized Controlled Clinical Trial

AIM : To evaluate and compare the clinical and radiographic success of zinc oxide eugenol, metapex and endoflas as obturating materials in pulpectomy of primary teeth at 3 and 6 months follow up. METHODOLOGY : A total of 60 carious primary molars with clinical signs and symptoms indicative of irreversible pulpitis were selected from 36 children, aged 4 to 9 years and free from any systemic disease who visited the outpatient ward of Department of Pedodontics, KSRIDSR, Tiruchengode between January 2015 till April, 2015. The teeth were selected on specific inclusion and exclusion criteria randomly divided into three groups A, B and C. The pulpectomy procedure was performed under rubber dam isolation after administration of local anaesthesia. The selected teeth were randomly obturated with zinc oxide eugenol in group A, metapex in group B and zinc oxide eugenol and endoflas as Group C. Post operative radiographs were taken immediately after obturation. All obturated teeth received an entrance restoration, followed by preformed stainless steel crown. The teeth were evaluated at 3 and 6 months respectively using clinical and radiographic criteria cited by Gupta and Das (2011). Clinical and radiographic success was scored by two well-trained pediatric dentists. Inter examiner reliability was correlated by using Cohen’s Kappa coefficient (k = 0.8). STATISTICS: Statistical analysis was done using SPSS version 17.0 (Chicago: SPSS Inc) with statistical significance set at p _ 0.05. Chi square test was employed for the statistical analysis. RESULTS AND CONCLUSION : Zinc oxide eugenol had 100 % overall success rate, followed by endoflas with 98.6% and metapex with 92.1%. Intergroup comparison of overall success was statistically significant (p = 0.0027). Both zinc oxide eugenol and endoflas showed 100% clinical success rate at 3 and 6 months interval. Metapex showed 100 % clinical success at the 3rd month, but it declined to 89.4 % in the 6th month follow up. Similary, inter group comparisons of clinical success between the three groups was highly statistically significant at the 6th month interval (p < 0.001). Intra group comparison of radiographic success was highly statistically significant for metapex (p < 0.001) and statistically significant for the endoflas (p = 0.045). Inter group comparison between the three groups was statistically significant at the 3rd and 6th month interval with p = 0.004 and p < 0.001 respectively

EXPLORING THE COMPETENCE OF PHYTOCHEMICAL COMPOUNDS TO COMBAT ANTHRACNOSE DISEASE OF CUCUMBER -AN IN SILICO APPROACH

Objective: Anthracnose is one of the diseases of cucumber caused by the fungus Colletotrichum lagenarium. The enzymes of fungal melanin biosynthesis pathway act as a potential target for the synthetic fungicides.
