The present work demonstrates the fabrication of novel thin film nanocomposite membranes incorporating surface functionalized Silicon nanoparticles (average size 15-20nm) for removal of water vapor from nitrogen gas. Silicon nanoparticles were synthesized using the inductively coupled plasma (ICP) technique. The nanoparticles were dispersed in deionized water to introduce hydroxyl functional groups on the surface. The surface functionalization was confirmed by infrared spectroscopy. The effect of nano-Si concentration on the water vapor permeation properties of the TFN membranes was investigated in detail. The hydroxyl functional groups resulted in significant improvement of surface hydrophilicity and roughness of the nanocomposite membranes which in turn enhanced the water solubilization. The small size of nanoparticles permitted extensive interaction between the nanoparticles and the thin film polyamide layer. Increase in the nano-Si concentration resulted in improvement of water vapor permeance and selectivity till 0.5w/w%, above which the selectivity decreased because of the interference in interfacial polymerization reaction due to the dilution of aqueous phase monomer and high loading of nanoparticles. Water vapor permeance in excess of 2200GPU with vapor/N<SUB>2</SUB> selectivity of 501 was obtained when the nano-Si loading was 0.5w/w%. The introduction of nano-Si in the polyamide membrane improved the stability of the nanocomposite membrane such that it slightly resisted the decrease in water vapor permeance with operating temperature.

Canopy architecture is one of the most critical components infl uencing photoassimilation, yield and quality of fruit crops; thus, it is logical to optimize suitable canopy form with high light interception effi ciency. In this study, the eff ectiveness of three forms of canopy architecture viz., open centre, Y trellis and espalier were assessed, under high density planting system of mango (833 plants ha − 1 ). Y trellis facilitated better availability of photosynthetic photon fl ux density (PPFD) in upper (793 μmol m − 2 s − 1 ) and lower canopy layers (487 μmol m − 2 s − 1 ) by exhibiting moderate interception of photosynthetic active radiation (PAR). Y-trellis also manifested relatively higher photosynthetic activity (6.07 μmol CO 2 m − 2 s − 1 and 5.24 μmol CO 2 m − 2 s − 1 ), stomatal conductance (0.194 μmol H 2 O m − 2 s − 1 and 0.172 μmol H 2 O m − 2 s − 1 ), carbohydrate and protein content in upper and lower canopy layers. On the other hand, espalier system demonstrated high rate of PAR interception and low photosynthetic activity. Mango canopy with Y-trellis and open centre forms provided better results in terms of fl owering intensity and fruit yield. Fruits from Y-trellis exhibited relatively better colour attributes, sucrose and β-carotene content. Alternatively, soluble solid contents, citric acid, carbohydrate and protein content were unaff ected with the training systems. It was evident from PCA biplots that Y-trellis had close proximity with light intensity, photosynthetic characteristics, fl owering intensity, yield, and fruit quality attributes. Moreover, path coeffi cient analysis indicated that PPFD, iPAR and photosynthetic rate ( Pn ) were the most important predictors for determining fl owering in mango. The fi ndings of the present study demonstrate that optimized canopy architecture is instrumental for eff ective utilization of radiation energy for higher fl owering intensity, yield and fruit quality in mango. Economic assessment of training system indicated that Y-trellis was more feasible system when cultivation was aimed to maximise the profi t with no restriction on investment. However under capital constraint situation open centre system was more profi table.

The objective of this work was to evaluate a thermotolerant yeast Issatchenkia orientalis DY252 as a microbial feed additive for ruminants. In the present study, the influence of volatile fatty acids (VFA) and temperature on oxygen uptake rate by I. orientalis DY 252 was investigated. It was evident that the oxygen uptake rate was decreased gradually as the VFA concentrations increased in a range of 30 to 120 mM. Although the oxygen uptake rate was not greatly affected by temperature in the range 37 to $43^{\circ}C$, a maximum value of $0.45mg\;O_2/g$ cell/ min was obtained at $39^{\circ}C$. With regard to the oxygen uptake rate by yeast, viability was found to be less important than the metabolic activity of yeast.

<P>Interactions between myoblasts and the surrounding microenvironment led us to explore the role of fibromodulin (FMOD), an extracellular matrix protein, in the maintenance of myoblast stemness and function. Microarray analysis of FMODkd myoblasts and in silico studies were used to identify the top most differentially expressed genes in FMODkd, and helped establish that FMOD-based regulations of integral membrane protein 2a and clusterin are essential components of the myogenic program. Studies in knockout, obese, and diabetic mouse models helped characterize the operation of a novel FMOD-based regulatory circuit that controls myoblast switching from a myogenic to a lipid accumulation fate. FMOD regulation of myoblasts is an essential part of the myogenic program, and it offers opportunities for the development of therapeutics for the treatment of different muscle diseases.</P>
