Muslim Entrepreneurs between India & the Gulf
In recent years the role of wealthy entrepreneurs in Muslim political, religious, and social life has been largely neglected. The authors reverse this trend by considering the practices and orientations of some Kerala Muslim businessmen, who unite the pursuit of particular business interests with efforts to produce a Muslim modernity
Adaptive mechanisms in dogs adopted from shelters: A behavioral assessment of the use of a synthetic analogue of the canine appeasing pheromone
Adaptation to a new socio-environment might represent a very hard step for sheltered dogs, because of a higher level of difficulty in coping with unfamiliar conditions. The adaptation process can be logically and scientifically related to the concept of stress and welfare, limiting the success rate of rehoming. A synthetic analogue of the Dog Appeasing Pheromone (Dog Appeasing Pheromone, DAP) is reported to have a reassuring effect in puppies and adult dogs in a wide variety of stressful situations. The aim of the current study was to investigate the effects of DAP (Adaptil® Ceva Vetem S.p.A.) in dogs re-homed from rescue shelters. The study was designed as a prospective open-label clinical trial. Significant decreases were observed in adult dogs for wandering in the house restlessly (p=0.022) and hiding fearfully in protected corners (p=0.033), whereas in puppies treatment with DAP significantly (p<0.05) improved the reaction towards unfamiliar dogs (p=0.048) and wandering in the house restlessly (p=0.022). In both adults and puppies a significant improvement in interaction with owners was observed. In particular, "looking continuously for the owners" and "following the owners everywhere like a shadow" were significantly improved (p=0.0012 and 0.0016 respectively) in adult dogs. Separation reactions revealed a significant decrease (p<0.05) and in puppies the tendency to vocalize in absence of the owner was also significantly reduced (p=0.0029). Both adults and puppies showed a decreased tendency to wake suddenly in the night (p=0.024 and p=0.026 respectively) and wander around the home (p=0.012 and p=0.026 respectively). In contrast, for house-training no significant difference was reported in adults, whereas for puppies there was a significant decrease (p<0.05) in the mean scores for urination and/or defecation wherever in the house and after coming home. Data regarding the overall assessment suggested a significant improvement in all the efficacy variables considered in the study. The analysis of owners' degree of satisfaction at the final visit showed that DAP treatment was considered successful by 84.4 % of owners. Results suggest that DAP might improve dogs' adaptability throughout the first weeks following adoption and can be considered a useful tool for reducing stress in re-homed dogs
Effect of Xylanase on the Technological Behaviour of Wheat Flours
The objective of this work is to investigate the effect of enzyme xylanase on the technological behaviour of wheat flours, particularly in alveograms and bread making, using two flour qualities and two bread making methods. The enzyme used was xylanase from Bacillus subtilis which is sold for mainly for baking applications. Breads were made applying both the French and the pan bread methods. Experts scored the external and internal characteristics of breads. Increase in enzyme concentration produced a decrease in maximum pressure (P) and tensile strength/extensibility (P/L) but deformation energy (W) remained almost constant in the alveogram. This means that the water released by the hydrolysis of insoluble pentosans has reduced the tenacity of the dough. The higher the enzyme concentration, the lower the dough consistency during kneading. Besides, the greatest improvement of quality was produced when xylanase was added to low quality flour and when the French type bread making method was applied.Fil: Osella, C..

Composition dependent electrochemical properties of earth-abundant ternary nitride anodes
Growing energy storage demands on lithium-ion batteries necessitate
exploration of new electrochemical materials as next-generation battery
electrode materials. In this work, we investigate the previously unexplored
electrochemical properties of earth-abundant and tunable Zn1-xSn1+xN2 (x = -0.4
to x = 0.4) thin films, which show high electrical conductivity and high
gravimetric capacity for Li insertion. Enhanced cycling performance is achieved
compared to previously published end-members Zn3N2 and Sn3N4, showing decreased
irreversible loss and increased total capacity and cycle stability. The average
reversible capacity observed is > 1050 mAh/g for all compositions and 1220
mAh/g for Zn-poor (x = 0.2) films. Extremely Zn-rich films (x = -0.4) show
improved adhesion; however, Zn-rich films undergo a phase transformation on the
first cycle. Zn-poor and stoichiometric films do not exhibit significant phase
transformations which often plague nitride materials and show no required
overpotential at the 0.5 V plateau. Cation composition x is explored as a
mechanism for tuning relevant mechanical and electrochemical properties, such
as capacity, overpotential, phase transformation, electrical conductivity, and
adhesion. The lithiation/delithiation experiments confirm the reversible
electrochemical reactions. Without any binding additives, the as-deposited
electrodes delaminate resulting in fast capacity degradation. We demonstrate
the mechanical nature of this degradation through decreased electrode thinning,
resulting in cells with improved cycling stability due to increased mechanical
stability. Combining composition and electrochemical analysis, this work
demonstrates for the first time composition dependent electrochemical
properties for the ternary Zn1-xSn1+xN2 and proposes earth-abundant ternary
nitride anodes for increased reversible capacity and cycling stability
