Some Aspects of Duality in Mathematical Programming Problems
No full textThe work exhibited in this thesis is an endeavor to achieve various duality results for minimax
fractional programming and multiobjective programming problems. The proposed
work encapsulates these results which are weaved into six chapters. The present thesis is
assembled into chapters as described below:
Chapter 1 is introductory and consists of definitions, notations and prerequisites of
the present work. A brief account of the related work studied by various authors in the
field and a summary of the thesis are also presented.
Chapter 2 presents a parametric dual model for nondifferentiable minimax fractional
programming (NMFP) problems. Optimality conditions and duality relations are acquired
using (p, r)-ρ-(η, θ)-invex suppositions. Two types of second-order dual models are proposed
for NMFP problem and usual duality results are developed under second-order B-
(p, r)-invex functions.
In Chapter 3, we present a novel concept of higher-order B-(p, r)-invex functions.
we construct a higher-order dual for NMFP problem and achieve duality results under
higher-order B-(p, r)-invexity. A numerical example is solved for finding optimal solution
of NMFP problem.
In Chapter 4, we develop second-order duality results for nondifferentiable multiobjective
fractional variational problem under second-order (F, α, ρ, d)-pseudoconvexity suppositions.
An illustration showing the existence of second-order (F, α, ρ, d)-pseudoconvex
functions is provided. An example is obtained to validate the theoretical results of weak
duality.
Chapter 5 presents a new pair of higher-order symmetric dual for multiobjective
programming problems involving support functions over arbitrary cones. We construct an
example of a non trivial function that shows the existence of higher-order K-η-convex functions.
Various duality relations are explored under aforesaid assumptions. Some special
cases are also examined to show that this work extends known results of the literature.
In Chapter 6, we propose a mixed type higher-order symmetric dual model for multiobjective
programming problems. Weak, strong and converse duality theorems are established
under higher-order K-(F, α, ρ, d)-convexity assumptions
Honey bee PTEN--description, developmental knockdown, and tissue-specific expression of splice-variants correlated with alternative social phenotypes.
No full textPhosphatase and TENsin (PTEN) homolog is a negative regulator that takes part in IIS (insulin/insulin-like signaling) and Egfr (epidermal growth factor receptor) activation in Drosophila melanogaster. IIS and Egfr signaling events are also involved in the developmental process of queen and worker differentiation in honey bees (Apis mellifera). Here, we characterized the bee PTEN gene homologue for the first time and begin to explore its potential function during bee development and adult life.Honey bee PTEN is alternatively spliced, resulting in three splice variants. Next, we show that the expression of PTEN can be down-regulated by RNA interference (RNAi) in the larval stage, when female caste fate is determined. Relative to controls, we observed that RNAi efficacy is dependent on the amount of PTEN dsRNA that is delivered to larvae. For larvae fed queen or worker diets containing a high amount of PTEN dsRNA, PTEN knockdown was significant at a whole-body level but lethal. A lower dosage did not result in a significant gene down-regulation. Finally, we compared same-aged adult workers with different behavior: nursing vs. foraging. We show that between nurses and foragers, PTEN isoforms were differentially expressed within brain, ovary and fat body tissues. All isoforms were expressed at higher levels in the brain and ovaries of the foragers. In fat body, isoform B was expressed at higher level in the nurse bees.Our results suggest that PTEN plays a central role during growth and development in queen- and worker-destined honey bees. In adult workers, moreover, tissue-specific patterns of PTEN isoform expression are correlated with differences in complex division of labor between same-aged individuals. Therefore, we propose that knowledge on the roles of IIS and Egfr activity in developmental and behavioral control may increase through studies of how PTEN functions can impact bee social phenotypes
Effect of fiber surface treatment on mechanical properties of carbon fiber reinforced composites
No full textME, MEDIn this work, different surface treatments: viz. Acetone desizing, nitric acid treatment, silane treatment, nitric acid treatment followed by silane treatment are performed on carbon fibers.
The modified carbon fibers are embedded in epoxy matrix and high quality 2-ply laminated composites are manufactured using vacuum bagging method. The interlaminar shear strength,flexural strength and flexural modulus of composites are improved by treatments. The
chemical bonds formed between carbon fibers and epoxy matrix as a result of silanization gave better results as compared to the mechanical interlocking between carbon fibers and matrix induced by etching using nitric acid. A significant improvement in interlaminar shear
strength (11 MPa) and flexural strength (488 MPa) of composites is achieved by treating the fibers with nitric acid for 5 minutes followed by silane treatment using 3-Aminopropyltrimethoxy
silane. This is attributed to creation of active sites and hydroxyl (-OH) groups on
fiber surface by nitric acid treatment which improved bonding between silane and carbon fibers
Impact of Covid-19 on Mental Health
No full textA pandemic affects people and society and creates disruption, anxiety, tension, embarrassment, and xenophobia. Provincial lockdowns were necessary due to the SARS CoV2's rapid human-to-human transmission to stop the disease's further spread. However, it is undeniable that the restrictive restrictions have had an impact on people's social and emotional wellness in all circumstances. Children may experience stress, difficulty, social disengagement, and an unfavourable environment that may have short- or long-term effects on their mental health. Specialists, medical professionals, and paramedics working as a front-line force to combat the COVID-19 incident may be more susceptible to nurture psychological health indications. Knowing how the COVID-19 episode affected various populations' emotional health is almost as important as knowing its clinical highlights, transmission scenarios, and executives. Public awareness campaigns that concentrate on the maintenance of psychological wellbeing in the larger context are urgently needed
Preliminary results from the Call to Action program
No full textRetreat environments are shown to provide emotional support and the opportunity for previous cancer patients to engage with fellow cancer survivors, experience therapeutic aspects of connecting with nature, and remove feelings of isolation, which are often present when undergoing traditional cancer treatment (Barber, 2012). Knights Cabin Cancer retreats was created in 2014 to improve health behavior post cancer diagnosis (see Lesser et al., 2019 for more information about the program). Preliminary findings of Knights Cabin retreats, which are no-cost retreats for participants and their supporters, show an improvement in mental health related QOL, physical activity, self-esteem, and perceived stress at the 3 and 6 month mark post-retreat. Adherence and motivation are challenging in cancer survivors due to the long-term adverse effects of treatment on psychosocial and physiological health. Thus, the aim of this report was to assess the impact of a behavioral phone intervention after participants attended a Knights Cabin Cancer retreat on health related QOL and physical activity.This poster won an Associate Vice-President, Research, Engagement, and Graduate Studies award (2020).
