This interpretation is an attempt at monitoring the presence of 'Others' in Zofia Nalkowska's autobiographical text as well as the ways in which that presence is featured within the perspective of the 'appropriate form', the key problem of all her fictions. 'Form is curiosity and hatred, and not a dress to be put on' - Nalkowska writes in one of her novels. Consequently, 'appropriate form' is more than a mere aesthetic category. An analysis of Nalkowska's relations with her mother, with men, and other women, reveals an ethical dimension of her aestheticism. Furthermore, this in-depth study of her presentation of 'Others' in the 'Diaries' leads to the identification of a number of paradoxes which seem to characterize any narcissistic story. The authoress of this article conduces with some surpise that egotism and narcissism do not necessarily go hand in hand; the latter is more closely connected to the paradoxes of private, intimate writing. This article is partly a polemical correction of one of her earlier studies (The stolen profile: Mother in Zofia Nalkowska's 'Diaries') published in Ruch Literacki (No 5, 2001).

The paper deals with the numerical treatment of the optimal control of drying of materials which may lead to cracks. The drying process is controlled by temperature, velocity and humidity of the surrounding air. The state equations dene the humidity and temperature distribution within a simpli ed wood specimen for given controls. The elasticity equation describes the internal stresses under humidity and temperature changes. To avoid cracks these internal stresses have to be limited. The related constraints are treated by smoothed exact barrier-penalty techniques. The objective functional of the optimal control problem is of tracking type. Further it contains a quadratic regularization by an energy term for the control variables (surrounding air) and barrier-penalty terms. The necessary optimality conditions of the auxiliary problem form a coupled system of nonlinear equations in appropriate function spaces. This optimality system is given by the state equations and the related adjoint equations, but also by an approximate projection onto the admissible set of controls by means of barrier-penalty terms. This system is discretized by nite elements and treated iteratively for given controls. The optimal control itself is performed by quasi-Newton techniques.
