Malayali young men and their movie heroes

Here we bring together masculinities and popular culture to think about how they are configured within the arena of cinema, focusing in on Kerala's two major male movie stars and the relationship they have with their young male fans. In their relative lack of interest in female stars and turn towards male stars young men are playing out an approach towards gendering which does not take as its foundation hierarchic or compulsory heterosexuality. Young men's tentative (and illicit, difficult) relationships with young women lack the substance of their relationships with each other and with their male movie heroes. We consider cinema as a forum for collective fantasy which acts as a source of helpful orientations, stars being particular nodes within this arena, dense points of transfer of desire, belief, self-affirmation or transformation and so on. Film audiences receive or subvert cinematic messages and form relationships with stars - whether in fantasy or actually - and with each other, mediated through cinematic modes of being or styles of doing. Another effect of cinema-related activities is to provide adolescent and post-adolescent boys with a safe segregated social space in which they can socialise, share information, try out fledgling masculine identities and grapple with the demands of emerging sexualities. The star makes possible identifications with the self- (for Mohan Lal, one who is working class and in solidarity with the poor, in Mammootty's case a solidly bourgeoios self); transformations of the self - opportunities through fan association work to distribute largesse like a high-caste wealthy patron; and an extended sense of self - the possiblity that through the fan association one might participate in the star's power and reach. In Kerala, unlike other states, fandom is not a matter of rivalry, political partisanship or even life and death. While there is a 'hard-core' central group who remain partisan and always committed to 'their' star, in general young men frequently shift associations and change allegiances. Yet the two heroes seem to embody different styles of hero and to have different types of appeal to audiences; sociologically, their fan bases trace slightly different social groupings. Mammootty has an affinity with roles implying powerful and high-status men in control, strong in family drama; Mohan Lal is admired for his abilities in romance, song, dance and fighting. One might wish to be like Mammootty but often feels that one already is in some way like Mohan Lal. Despite considerable overlap and dispute, Mammootty and Mohan Lal embody and perform different styles of manliness, none of which one could dispense with in one's potential repertiore. Both Mammootty and Mohan Lal are necessary in a full fantasy life and a necessarily internally fragmented and shifting gendered identity. Cinema also relates to ethnicity. Mammotty allows young non-Muslim men to experience a fantasy relationship with a powerful mature Muslim man, a community coded 'other' in Kerala. A twist to this is that (similar to analyses of white anglo masculinities and work on the 'blackness' of Elvis) we find working class Hindu masculinity, while explicitly defined in opposition to the Muslim other, at another level actually relies upon an incorporation of aspects of masculinity especially associated in the cultural landscape with Muslimness. In a more mediated and disguised manner, Mohan Lal also plays with elements of fantasy identity culturally coded by young Hindus as 'Muslim'

Growth-rate-dependent dynamics of a bacterial genetic oscillator

Gene networks exhibiting oscillatory dynamics are widespread in biology. The minimal regulatory designs giving rise to oscillations have been implemented synthetically and studied by mathematical modeling. However, most of the available analyses generally neglect the coupling of regulatory circuits with the cellular "chassis" in which the circuits are embedded. For example, the intracellular macromolecular composition of fast-growing bacteria changes with growth rate. As a consequence, important parameters of gene expression, such as ribosome concentration or cell volume, are growth-rate dependent, ultimately coupling the dynamics of genetic circuits with cell physiology. This work addresses the effects of growth rate on the dynamics of a paradigmatic example of genetic oscillator, the repressilator. Making use of empirical growth-rate dependences of parameters in bacteria, we show that the repressilator dynamics can switch between oscillations and convergence to a fixed point depending on the cellular state of growth, and thus on the nutrients it is fed. The physical support of the circuit (type of plasmid or gene positions on the chromosome) also plays an important role in determining the oscillation stability and the growth-rate dependence of period and amplitude. This analysis has potential application in the field of synthetic biology, and suggests that the coupling between endogenous genetic oscillators and cell physiology can have substantial consequences for their functionality.Comment: 14 pages, 9 figures (revised version, accepted for publication

Effects of whey protein concentrate on shelf life of cookies using corn and sunflower oils

The objective of this work was to study the effect of whey protein concentrate (WPC) on shelf life of cookies using corn and sunflower oils as fat source. Wheat flour was partially replaced by WPC with levels of 5, 7.5, 10 and 15 %. A User Defined Design was used and the three following responses were measured: peroxide index (meqO2/kg), flavour (score from 1-10) and rancidity (detectable and non-detectable) at 0, 7, 14, 21 and 70 days of storage. Results show that during storage peroxide index (PI) increases in all cookies samples. However a significant decrease was found when corn oil was used instead of sunflower oil and when the level of WPC goes from 0% to 15%. Regarding sensory evaluation, all cookies were evaluated as acceptable (scored flavour ≥ 6) and no rancid flavour was perceived, except for two samples which were assigned with 5 and rancid flavour was considered as detectable; these samples correspond to cookies evaluated at day 70, elaborated with sunflower oil and the lowest dose of WPC. No significant differences were found in cookies flavour prepared with different oils. On the other hand and relative to the level of WPC replacement, differences were found by the panel at days 0 and 7, a reduction in assigned score when WPC dose was increased, however this difference was not significant in the subsequent assessment days. According to research results, an increase in stability was clearly obtained in cookies elaborated with corn oil and the highest concentration of WPC.Fil: Erben, Melina.

Fault-tolerant control under controller-driven sampling using virtual actuator strategy

We present a new output feedback fault tolerant control strategy for continuous-time linear systems. The strategy combines a digital nominal controller under controller-driven (varying) sampling with virtual-actuator (VA)-based controller reconfiguration to compensate for actuator faults. In the proposed scheme, the controller controls both the plant and the sampling period, and performs controller reconfiguration by engaging in the loop the VA adapted to the diagnosed fault. The VA also operates under controller-driven sampling. Two independent objectives are considered: (a) closed-loop stability with setpoint tracking and (b) controller reconfiguration under faults. Our main contribution is to extend an existing VA-based controller reconfiguration strategy to systems under controller-driven sampling in such a way that if objective (a) is possible under controller-driven sampling (without VA) and objective (b) is possible under uniform sampling (without controller-driven sampling), then closed-loop stability and setpoint tracking will be preserved under both healthy and faulty operation for all possible sampling rate evolutions that may be selected by the controller
