Abstract
Rosin‐modified polyesteramide resins are prepared covering a wide range of oil lengths by partial replacement of hydroxy ethyl fatty acid amides employed in resin formulations by rosin‐diethanolamine derivative without affecting the resin constants. This is followed by a study of the optimum amount of modifier which improve the resins performance and durability without affecting the other properties. Optimum modifier concentration and durability characteristics are then determined.

Abstract
Copper and nickel 1,8 binaphthalocyanines were prepared by the urea fusion method. The proposed structure of these compounds was confirmed via micro‐analytical, volumetric and spectrophotometry methods. The prepared binaphthalocyanines compounds showed excellent pigmentary properties on evaluating them according to specific international standard methods.

Cobalt, Nickel and Copper hexaazabiphthalocyanine were prepared by the reaction of pyridine 2,3‐dicarboxylic acid anhydride, pyromillitic acid dianhydride, with urea and metal…
Abstract
Cobalt, Nickel and Copper hexaazabiphthalocyanine were prepared by the reaction of pyridine 2,3‐dicarboxylic acid anhydride, pyromillitic acid dianhydride, with urea and metal salt in presence of ammonium molybdate catalyst. The reaction is carried out in an inert solvent [nitrobenzene]. The structure of the prepared compound was confirmed by microanalytical and pectrophotometric methods. Evaluation of the highly coloured products according to international standard methods showed their suitability as excellent pigments for coating applications.

Abstract
Rosin‐diethanolamin derivative is used partially or completely as the source of polyol for the formation of recently modified polyesteramid resins. Parameters affecting the reaction between abietic acid (the main constituent of rosin) and diethanolamine, in azeotropic solvent using Dean and Stark apparatus, are studied.

Abstract
Most of the “alkylolamides” are derived from ethanola‐mines and fatty acids like stearic, lauric, myristic and oleic. The general method of preparation of these compounds involves the use of low molecular weight aminohydroxy compounds and acylation of amino group with higher fatty acids. Amino group may be primary or secondary. Also, hydroxyl group may be more than one.

Abstract
Various rosin‐modified polyesteramide resins are formulated and evaluated for their insecticidal activity. Five kinds of pyrethroid and organophosphorus insecticides with trade names Neo‐Pynamin Forte, Gokilaht, Neo‐Pynamin, Sumithrin and Cyanox are studies. American Cockroaches (Periplaneta americana) are the target insect.

Abstract
Various polyesteramide resins are prepared in which a stoichiometric amount of hydroxy ethyl fatty acid amides (diol) are replaced by the bifunctional nicotinic acid and aisonicotinic acid derivatives of diethanolamine and triethanolamine without affecting the resin constants. The inclusion of nicotinyl and isonicotinyl residues would expect to prevent microbial growth and may also act as corrosion inhibitor.

Abstract
The asymptotic bias and variance of a general class of local polynomial estimators of M-regression functions are studied over the whole compact support of the multivariate covariate under a minimal assumption on the support. The support assumption ensures that the vicinity of the boundary of the support will be visited by the multivariate covariate. The results show that like in the univariate case, multivariate local polynomial estimators have good bias and variance properties near the boundary. For the local polynomial regression estimator, we establish its asymptotic normality near the boundary and the usual optimal uniform convergence rate over the whole support. For local polynomial quantile regression, we establish a uniform linearization result which allows us to obtain similar results to the local polynomial regression. We demonstrate both theoretically and numerically that with our uniform results, the common practice of trimming local polynomial regression or quantile estimators to avoid “the boundary effect” is not needed.

Abstract
Purpose
This chapter approaches the topic of teaching the Western scholarly tradition in non-Western countries like the United Arab Emirates (UAE) from three perspectives employing the following metaphors: as a Public Servant motivated by public service to the goals and aims of the country’s development articulated by UAE rulers and its citizens; as Cultural Diplomat, representing the Western tradition and its scholarly achievements while respecting other traditions; and as Intellectual Imperialist, aiming at a colonising incorporation of the UAE into the Western academic world.
Methodology/approach
The main methodology adopted is the Weberian ideal type, located within a comparative and historical context that produces the metaphors as analytically possible perspectives as a western expatriate faculty member. Additional critique is drawn from Bourdieu, Said, Freire, Giroux, Foucault, Goffman and cross-cultural organisation studies.
Findings
The findings consist of an analytic framework consisting of public servant, cultural diplomat and intellectual imperialist as a set of conceptions for analysing possible orientations of Western expatriate academics in developing countries.
Social implications
The implications are threefold: on a personal level, what experientially does each of the metaphors mean for one’s sense of identity, profession, values and relationships; on a pedagogical level, what principles and values distinguish the curriculum and teaching styles as well as orientation to Arab and Islamic scholarship; and politically, what is the potential impact and unintended consequences for the indigenous culture, sovereignty and societal survival of a country under the heavy influence of globalisation. The contention of this chapter is that one cannot avoid adopting one or more of these roles and may even perform in contradictory ways.
Originality/value
The originality is in establishing a new set of analytic categories drawing on post-colonial, diplomacy and critical studies.
