On Second-Order Duality in Nondifferentiable Continuous Programming  [PDF]
I. Husain, Santosh K. Shrivastav
American Journal of Operations Research (AJOR) , 2012, DOI: 10.4236/ajor.2012.23035
Abstract: A Mond-Weir type second-order dual continuous programming problem associated with a class of nondifferentiable continuous programming problems is formulated. Under second-order pseudo-invexity and second-order quasi-invexity various duality theorems are established for this pair of dual continuous programming problems. A pair of dual continuous programming problems with natural boundary values is constructed and the proofs of its various duality results are briefly outlined. Further, it is shown that our results can be regarded as dynamic generalizations of corresponding (static) second-order duality theorems for a class of nondifferentiable nonlinear programming problems already studied in the literature.

I. Husain, Vikas K. Jain
American Journal of Operations Research (AJOR) , 2012, DOI: 10.4236/ajor.2012.24063
Abstract: Fritz John and Karush-Kuhn-Tucker type optimality conditions for a nondifferentiable multiobjective variational problem are derived. As an application of Karush-Kuhn-Tucker type optimality conditions, Mond-weir type second-order nondifferentiable multiobjective dual variational problems is constructed. Various duality results for the pair of Mond-Weir type second-order dual variational problems are proved under second-order pseudoinvexity and second-order quasi-invexity. A pair of Mond-Weir type dual variational problems with natural boundary values is formulated to derive various duality results. Finally, it is pointed out that our results can be considered as dynamic generalizations of their static counterparts existing in the literature.

Abstract: in this work the present day mass functions (pdmf) of t-tauri stars (tts) which are in the pre-main sequence (pms) evolutionary phase of their evolution in the taurus-auriga molecular cloud complex have been calculated. for this purpose, by applying our modified stellar evolutionary code, stellar models in the mass range 0.1 - 2.5 are used to determine the mass and age mass of tts. the obtained mass function is compared with the mass function of miller & scalo (1979). the age found for tts is around 1 - 3 × 106 yr and the mass function is about 0.6440.348. from these results, we have calculated the stellar birthrate as about 1.3 × 10-7 yr -1 in this region.
The Behaviour of Superalloys in Marine Gas Turbine Engine Conditions  [PDF]
I. Gurrappa, A. K. Gogia, I. V. S. Yashwanth
Journal of Surface Engineered Materials and Advanced Technology (JSEMAT) , 2011, DOI: 10.4236/jsemat.2011.13022
Abstract: This paper presents hot corrosion results carried out systematically on the selected nickel based superalloys such as IN 738 LC, GTM-SU-718 and GTM-SU-263 for marine gas turbine engines both at high and low temperatures that represent type I and type II hot corrosion respectively. The results were compared with advanced superalloy under similar conditions in order to understand the characteristics of the selected superalloys. It is observed that the selected superalloys are relatively more resistant to type I and type II hot corrosion when compared to advanced superalloy. In fact, the advanced superalloy is extremely vulnerable to both types of hot corrosion. Subsequently, the relevant reaction mechanisms that are responsible for slow and faster degradation of various superalloys under varied hot corrosion conditions were discussed. Based on the results obtained with different techniques, a degradation mechanism for all the selected superalloys as well as advanced superalloy under both types of hot corrosion conditions was explained. Finally, the necessity as well as developmental efforts with regard to smart corrosion resistant coatings for their effective protection under high temperature conditions was stressed for their enhanced efficiency.
New Formula for Geometric Stiffness Matrix Calculation  [PDF]
I. Němec, M. Trcala, I. ?ev?ík, H. ?tekbauer
Journal of Applied Mathematics and Physics (JAMP) , 2016, DOI: 10.4236/jamp.2016.44084
Abstract: The standard formula for geometric stiffness matrix calculation, which is convenient for most engineering applications, is seen to be unsatisfactory for large strains because of poor accuracy, low convergence rate, and stability. For very large compressions, the tangent stiffness in the direction of the compression can even become negative, which can be regarded as physical nonsense. So in many cases rubber materials exposed to great compression cannot be analyzed, or the analysis could lead to very poor convergence. Problems with the standard geometric stiffness matrix can even occur with a small strain in the case of plastic yielding, which eventuates even greater practical problems. The authors demonstrate that amore precisional approach would not lead to such strange and theoretically unjustified results. An improved formula that would eliminate the disadvantages mentioned above and leads to higher convergence rate and more robust computations is suggested in this paper. The new formula can be derived from the principle of virtual work using a modified Green-Lagrange strain tensor, or from equilibrium conditions where in the choice of a specific strain measure is not needed for the geometric stiffness derivation (which can also be used for derivation of geometric stiffness of a rigid truss member). The new formula has been verified in practice with many calculations and implemented in the RFEM and SCIA Engineer programs. The advantages of the new formula in comparison with the standard formula are shown using several examples.

American Journal of Analytical Chemistry (AJAC) , 2012, DOI: 10.4236/ajac.2012.33037
Abstract: Two simple and sensitive spectrofluorimetric (method Ι) and spectrophotometric (method ΙΙ) methods have been developed for the determination of some chloride containing toothpastes and panthenol-containing cosmetic preparations respectively. Method Ι is based on quantitative fluorescence quenching of (terbium-salicylate-hexamine ternary complex) by fluoride which could be measured at λem/λex of 547 nm/322 nm. The ΔF-concentration plot was rectilinear over the concentration range of 0.5 - 20 μg/ml. Method ΙΙ depends reaction of panthenol with nitrobenzoxadiazole chloride (NBD-Cl) and measuring the absorbance of the resultant product at 480 nm. The absorbance-concentration plot was rectilinear over the concentration range of 2 - 20 μg/ml.
Ultrasound-Guided Peri-Lymphatic and Peri-Neural Corticosteroid Injection as an Adjuvant to Pain and Lymphedema Management in Terminal Cancer: Two Case Reports  [PDF]
Clark K. Choi, David I. Rosenblum
Open Journal of Anesthesiology (OJAnes) , 2012, DOI: 10.4236/ojanes.2012.25054
Abstract: We are reporting two patients presented with intractable cancer pain that was treated with a novel application of an ultrasound-guided peripheral nerve block using corticosteroid. This technique offered relief to both patients whom otherwise their cancer pain was difficult to manage. The first patient developed lymphedema to the right axilla from metastatic squamous cell carcinoma. After multiple injections were deposited around the brachial plexus, lymphedema on the right axilla decreased slightly in size; however, range of motion improved post-procedure prior to his discharge one week later. In the second patient with left inguinal lymphadenopathy from metastatic left ureteral transitional cell carcinoma, there was a dramatic reduction in lymphedema in the left groin and leg as well as a considerable decrease in pain score during a two week follow-up after the peri-neural and peri-lymphatic femoral block. A 75% improvement in patient satisfaction was reported in the office visit’s questionnaire form. Corticosteroids can be used as an adjuvant to peripheral nerve block to decrease the pain secondary to lymphedema caused by the inflammatory response from metastatic cancer. This application can provide an alternative way to manage severe cancer-related pain caused by lymphedema in both upper and lower limbs.
Sustainable Polymers Derived From Naturally Occurring Materials  [PDF]

Nearly 95% of monomers or chemical intermediates used today are based on fossilized carbon such as coal and petroleum. This has resulted in a high rate of depletion of fossilized reserves, continuous escalation in petroleum prices, environmental impact with the increase in emission of greenhouse gases, and accumulation of non-biodegradable waste on earth. Current global main challenges are moving towards green sources - need for vast new and sustainable material resources; supplement, reuse and replace petroleum based polymeric materials; biodegradability of materials to prevent build up of waste; toxicity associated with the preparation, usage and environmental safety. Recent investigations are therefore, focused on procuring materials from the plant resources, agricultural waste and their utility in synthesis of polymeric materials. Amongst the polymers derived from natural resources poly(lactic acid) is a leading candidate. Commercial quantities of natural oil-based polyols such as castor, soya bean oil have been available over the past several years and currently used for synthesis of  polyesters, polyurethanes etc, but today many other  natural materials are also being investigated. It should be possible to produce sustainable polymers commercially and economically.
