Comparative Studies on 'Nucellar', 'Sathgudi' and 'Local' Sweet Orange (Mosambi) (Citrus sinensis Osbeck.) under Marathwada Conditions

The present investigation was conducted during Ambia bahar season in the year 2011-12. The experiment was laid out in randomized block design with three treatments and seven replications. The variety 'Nucellar' recorded maximum average height of plant, spread of tree, stem girth, number of branches per tree, was early to mature, had highest yield, fruit size, number of segments per fruit, weight of fruit, peel weight, peel thickness of fruit, TSS, and pH, while, the variety 'Sathgudi' recorded maximum juice weight, with low peel-to-juice ratio. The taste of fruits of Local mosambi was sweeter, with less acidity than the other two varieties. Maximum number of seeds per fruit was recorded in Local mosambi. Highest average pH and ascorbic acid content in fruit juice was recorded in cv. Nucellar. Therefore, on the basis of results obtained in the present investigation, it is suggested that of the three varieties studied, 'Nucellar' is the best in yield and other parameters, with 'Sathgudi' being the second best

Precise identification of objects in a hyperspectral image by characterizing the distribution of pure signatures

Hyperspectral image (HSI) has been widely adopted in many real-world applications due to its potential to provide detailed information from spectral and spatial data in each pixel. However, precise classification of an object from HSI is challenging due to complex and highly correlated features that exhibit a nonlinear relationship between the acquired spectral unique to the HSI object. In literature, many research works have been conducted to address this problem. However, the problem of processing high-dimensional data and achieving the best resolution factor for any set of regions remains to be evolved with a suitable strategy. Therefore, the proposed study introduces simplified modeling of the hyperspectral image in which precise detection of regions is carried out based on the characterization of pure signatures based on the estimation of the maximum pixel mixing ratio. Moreover, the proposed system emphasizes the pixel unmixing problem, where input data is processed concerning wavelength computation, feature extraction, and hypercube construction. Further, a non-iterative matrix-based operation with a linear square method is performed to classify the region from the input hyperspectral image. The simulation outcome exhibits efficient and precise object classification is achieved by the proposed system in terms classified HSI object and processing time

Federation of Piling Specialists’ casing extraction review

During construction of rotary bored piles it is necessary to install a temporary casing to prevent the collapse of material into the open bore and provide edge protection. T he preferred method of removal for some contractors is by means of the handling crane. The Federation of Piling Specialists (2010) released guidance to predict the load developed in the removal of casings. This paper investigated whether the recommended constants applied to the overburden and clay terms were reasonable for various casing diameter s , embedment and depth of overburden. A series of five ce ntrifuge tests were conducted where loads were recorded as casings were extracted. Results showed that the FPS method over predicted the pull - out force and indicated that the adhesion factor, α , and angle of dilation between the casing and soil, tan δ , are not constant. This paper proposes a new method of predicting extraction forces which was found to predict forces to within ±10% of those measured in centrifuge tests

Influence of geometry on the bearing capacity of sheet piled foundations

Bored concrete piles are commonly used to support moderate loads from buildings in urban areas. At the end of their 25-30 year lifespan these structures are decommissioned but their foundations are left in place. These cannot be inspected hence the bearing capacity cannot be accurately verified. A hybrid foun- dation comprising sheet piles and a pilecap to mobilise shaft friction and end bearing was demonstrated to be a feasible and sustainable alternative to cast in-situ concrete piles. This research investigated the influence of sheet pile geometry on ultimate bearing capacity. A centrifuge test at 50 g was performed in over- consolidated clay where a square hybrid sheet pile group was ax ially loaded and vertical settlements recorded. Results indicated a square sheet pile group offers 70% greater capacity than a circular sheet pile group of similar surface area and 24% improved performance over the solid p ile loaded in the same test. Analysis of results suggested that the ultimate bearing capacity of the square sheet pile group compared with a solid pile of equivalent base area were within 0.2%, emphasising the importance of shape on capacity and the feasibility of the hybrid system as a viable foundation solution

Uncertainty Analysis of Hollow Airfoil Composite Structure by Using Finite Element Method

by using Monte Carlo method. A three dimensional static analysis of large displacement type has been carried out. Finite element analysis of NACA0012 airfoil composite structure has been carried out and uncertainty in Maximum Deflection is analyzed. Maximum Deflection was objective function. Chord length , beam length ,elastic modulus in XY,YZ,XZ and shear modulus of epoxy graphite in  XY,YZ,XZ, ply angle and ply thickness of airfoil section, force are varied within effective range and their effect on Maximum Deflection has been analyzed. In order to validate the results, one loop of simulation is benchmarked from results in literature. Ultimately, best set of probabilistic design variable is proposed to reduce Maximum Deflection under static loadin

Biodiesel from Thevetia peruviana seed oil with dimethyl carbonate using as an active catalyst potassium-methoxide

The transesterification of Thevetia peruviana seed oil with dimethyl carbonate (DMC) for preparing biodiesel has been studied using as an active catalyst potassium-methoxide (KOCH3). The effects of reaction conditions: Molar ratio of dimethyl carbonate to Thevetia peruviana seed oil, catalyst concentration, reaction time and agitation speed on dimethyl esters (DMC-Tp-BioDs) yield were investigated. The highest DMC-Tp-BioDs yield could reach 97.1% at refluxing temperature for 90 min with molar ratio of DMC-to-oil 5:1 and 2.0% w/w KOCH3 (based on oil weight). The fuel properties of the produced DMC-Tp-BioDs were compared with the ASTM D6751-02 biodiesel standard

A rare case of cerebellar toxicity after prolonged use of metronidazole: a case report

Metronidazole, a commonly used antiprotozoal and antibacterial medication is usually a safe and rarely reported to cause serious side effects. Major nervous side effects are peripheral ones, while central toxicity is rare. Following the discontinuation of the medication, clinical improvement is seen in the most cases. A 62 years old female patient was presented to hospital after experiencing the symptoms of an unsteady gait, difficulty in walking, impaired coordination of arms and legs, slurring of the speech, headache, tingling and numbness of both the feet and ascending limb weakness following intake of 400 mg metronidazole TDS daily for 2 months. The motor system examination revealed reduced muscle power, and DTR (Deep tendon reflex) was found to be 2+, except ankle reflex absent, while examination of sensory system showed, decrease pain and joint vibration sense up to the neck with absent planter reflex. The axial magnetic resonance imaging study of the brain showed bilateral symmetric hyperintensity involving both dentate nuclei in FLAIR image. The patient’s clinical conditions, on the other hand was deteriorated even after the discontinuation of the medication, hence injection methylprednisolone was given as an empirical therapy and was proved to be successful, and patient was recovered completely
