A New Class of Generalized Close-to-Starlike Functions Defined by the Srivastava-Attiya Operator

Acta Mathematica Sinica,English Series 2013年第5期29卷 833-840页

作者： H.M.SrIVASTAVA Dorina RADUCANU Grigore S.SLGEAN Department of Mathematics and Statistics University of Victoria Faculty of Mathematics and Computer Science Transilvania University of Brasov Faculty of Mathematics and Computer Science Babe s-Bolyai University

In this paper, we consider a new class CS＊s,b of generalized close-to-starlike functions, which is defined by means of the Srivastava-Attiya operator Js,b involving the Hurwitz-Lerch Zeta function φ（z, s, a）. Basic results such as inclusion relations, coefficient inequalities and other interesting properties of this class are investigated. relevant connections of some of the results presented here with those that were obtained in earlier investigations are pointed out briefly.

Analytic Functions related with the Hyperbola

引用

Chinese Annals of Mathematics,Series B 2013年第4期34卷 515-528页

作者： dorina r DUCANU Faculty of Mathematics and Computer Science Transilvania University of Brasov

The author considers a new class SHm λμ(α) of normalized analytic functions defined by a diferential operator. Several basic properties and characteristics of the functions belonging to the class SHm λμ(α) are investigated. These include integral representations, coefcient bounds, the Fekete-Szego¨ problem, class-preserving operators and T δ-neighborhoods.

Carob (Ceratonia siliqua L.) fruit pulp from 12 wild and 8 domesticated trees from 15 Moroccan localities were investigated for their polyphenols contents: total polyphenols content (53.22 - 118.04 mg and 57.46 - 183.31 mg), total flavonoids (1.41 - 4.83 mg and 1.62 - 7.46 mg) and condensed tannins (1.47 - 7.36 mg and 1.85 - 6.66 mg) in one carob fresh pulp for wild and domesticated trees, respectively. Fruit pulp from trees in the same region shows variable contents in polyphenols, flavonoids and condensed tannins.

Environmental Friendly Lightweight Material from Natural Fibers of Oil Palm Empty Fruit Bunch

引用

Journal of Materials Science and Chemical Engineering 2015年第7期3卷 190-195页

Indonesia is the most producer of crude palm oil (CPO) worldwide with production more that 25 million tons in 2013. Through increasing production of CPO the wastes generated are growing up as well. The empty fruit bunch of oil palm (EFB) is one of the solid waste (biomass) which is generated at the palm oil mill. Its amount is equivalent to the CPO production, but only about 50% of its weight are good fibers for further usage as industrial raw material. The EFB fiber consists an interesting honey comb/lightweight structure. By mixing the EFB natural fiber with bio binding agent based on potato the environmental friendly materials (biocomposites) can be produced which are 100% biodegadrable. The biocomposites with 2 mm thickness have strengthness about 7 GPa according to the 3 points bending test standard of DIN 53 457. After coating process the environmental friendly lightweight materials with density less than 0.4 g/cm3 will be ready to be implemented for different technical applications.
