Muon g-2 through a flavor structure on soft SUSY terms

In this work we analyze the possibility to explain the muon anomalous magnetic moment discrepancy within theory and experiment through lepton flavor violation processes. We propose a flavor extended MSSM by considering a hierarchical family structure for the trilinear scalar Soft-Supersymmetric terms of the Lagranagian, present at the SUSY breaking scale. We obtain analytical results for the rotation mass matrix, with the consequence of having non-universal slepton masses and the possibility of leptonic flavour mixing. The one-loop supersymmetric contributions to the leptonic flavour violating process $\tau \to \mu\gamma$ are calculated in the physical basis, with slepton flavour mixed states, instead of using the well known Mass Insertion Method. We present the regions in parameter space where the muon g-2 problem is either entirely solved or partially reduced through the contribution of these flavor violating processes.Comment: 21 pages, 7 figures. Changes on version 3: In order to obtain the complete result for muon g-2 in the limit of non-flavor violation we added the terms given in the appendix. We redid the graphics and numerical analysis including these changes. We also corrected some typos and changed the order of figure

Biohydrogen Production from Cellulose by Clostridium termitidis and Clostridium beijerinckii.

The purpose of this study was to determine Clostridium termitidis microbial kinetics on glucose, cellobiose, and cellulose, and to assess its co-culture with Clostridium beijerinckii for hydrogen production. Microbial kinetics parameters of the mesophilic, cellulolytic, and hydrogen producer C. termitidis were determined on glucose and cellobiose using MATLAB for modelling biomass growth and substrate consumption. Hydrogen yields on these substrates were 1.99 and 1.11 mol H2 mol-1 hexose equivalent, respectively. C. termitidis microbial kinetics in mono-culture and in co-culture with mesophilic hydrogen producer C. beijerinckii were also investigated under agitated and non-agitated conditions, with hydrogen yields of 1.46 and 2.11 mol H2 mol-1 hexose equivalentadded for agitated mono-culture and co-culture, respectively, as compared with 1.45 and 1.92 mol H2 mol-1 hexose equivalentadded in unagitated cultures. Soluble metabolites were also included in the mathematical model. Moreover, co-culturing of C. termitidis and C. beijerinckii on cellulose was proven to enhance hydrogen production directly from a complex substrate like cellulose under mesophilic conditions

Biobutanol production from cellulosic and sugar-based feedstock from the corn plant

In this thesis, biobutanol production by biological fermentation was investigated from the corn plant, integrating two approaches. The first one was to utilize corn cobs, a cellulosic-based material. The second, using a new sugar-based material, sugarcorn juice. Utilizing suitable Clostridia strains for each substrate, these approaches converged into a biorefinery concept to produce renewable biofuels in Ontario, Canada. The corn cob pretreatment was carried out by a dilute acid method resulting in temperature as the variable with most significant effect towards glucose liberation. The enzymatic hydrolysis was performed utilizing a very low concentration of an enzymatic stock solution with approximately 44% of hydrolysis conversion. Biobutanol fermentation was pursued utilizing a Clostridium beijerinckii strain and cellulosic biobutanol was produced in a concentration of 4.42 g L-1 at 48h with 97% of reducing sugars utilization. Different ABE fermentations by Clostridium saccharobutylicum ATTC BAA-117 using glucose, fructose, sucrose, and a mix of them, resulted in butanol production as high as 12-14 g L-1. For the first time, sugarcorn juices from Canadian corn hybrids, were characterized and proven as a suitable medium for biobutanol production. Variation in sugar composition of sugarcorn juices across different hybrids and growth seasons were observed during this study, from 102 g L-1 to 145 g L-1, with fructose, glucose and sucrose accounting for about 80%. Clostridium beijerinckii 6422 produced 8.49 g L-1 of butanol over 257h of fermentation utilizing sugarcorn juice as substrate. It had a biphasic fermentation where acids accumulation happened at the beginning of fermentation. Interestingly, at the end of the fermentation butyric acid was reactivated and the butanol production shifted towards butyric acid production. Clostridium saccharobutylicum produced 11.05 g L-1 of butanol over 227 h of fermentation utilizing sugarcorn juice as substrate. Both strains could utilize sucrose, fructose and glucose concomitantly. There is enough evidence to agree that Clostridium saccharobutylicum has a PTS-sucrose system which allows the cell to transport sucrose inside the cell. The proposed Canadian sugarcorn (CANSUG) biorefinery can commercially generate biofuels and biochemicals while limiting wastes, offer environmental benefits to the energy sector, and strengthen the Canadian bio-economy

Eternal Sunshine of the Solar Panel

The social dynamics of residential solar panel use within a theoretical population are studied using a compartmental model. In this study we consider three solar power options commonly available to consumers: the community block, leasing, and buying. In particular we are interested in studying how social influence affects the dynamics within these compartments. As a result of this research a threshold value is determined, beyond which solar panels persist in the population. In addition, as is standard in this type of study, we perform equilibrium analysis, as well as uncertainty and sensitivity analyses on the threshold value. We also perform uncertainty analysis on the population levels of each compartment. The analysis shows that social influence plays an important role in the adoption of residential solar panels
