n="justify"> The review outcome represents the optimum catalytic conditions for the production of hydrogen using hydrotalcite derived catalysts. It covers dry and steam reforming of methane, steam reforming of methanol and ethanol to hydrogen. The review also revealed the specific properties of hydrotalcite derived catalysts for the reactions. Among catalyst investigated, Ni & Fe promoted Al-Mg containing hydrotalcite catalyst perform best (99%) for dry reforming of methane at 250°C. For steam methane reforming, Ni containing ca-aluminates hydrotalcite catalyst act as the best (99%) at 550°C. Cu-supported Zn-Al-containing catalyst performs the best (99.98%) for steam reforming of methanol at 300°C whereas Cu impregnated Mg-Al containing hydrotalcite is the best (99%) for steam reforming of ethanol at 200°C - 600°C.

This paper describes the finite element (FE) analysis technique to predict fatigue life us.ng the narrow band frequency response approach. The life prediction results are useful for improving the component design methodology at the very early development stage. The approach is found to be suitable for a periodic loading but requires very large time records to accurately describe random loading processes. This paper is aimed at investigating the effects of surface treatments on the fatigue life of the free piston linear engine’s components. Finite element modelling and frequency response analysis were conducted us.ng computer aided design and finite element analysis commercial codes, respectively. In addition, the fatigue life prediction was carried out us.ng finite element based fatigue analysis commercial code. narrow band approach was specially applied to predict the fatigue life of the free piston linear engine cylinder block. significant variation was observed between the surface treatments and untreated cylinder block of free piston engine. The obtained results indicated that nitrided treatment yielded the longest life. This approach can determine premature products failure phenomena, and therefore can reduce time to market, improve product reliability and customer confidence.

The main objective of this investigation was to study the time effect during solid state bioconversion (ssB) on total phenolics content (TPC) and antioxidant activity (AoxA) of common beans to improve antihypertensive functionality. Cooked cotyledons of dehulled common beans were inoculated with a suspension of R. oligosporus.nRRL 2710 (1 × 106 spores/mL), and incubated at 35℃ for times of 24, 36, 48, 60, 72, 84, 96 and 108 h (after 108 h the cotyledons showed off odor). Flours from bioprocessed dehulled common bean from each incubation time were blended with their corresponding milled seed coats. The best time for producing bioprocessed common bean (added with seed coats) functional flour with the highest AoxA (ORAC value = 17,468 μmol Trolox equivalents (TE)/100 gsample, dw;ABTs value = 13,505 μmol TE/100 gsample, dw) was 108 h. The ssB process substantially increased TPC and total hydrophilic AoxA and antihypertensive potential of common beans in 2.24, 2.45 - 2.73 and 6769 times, respectively. Proteins hydrolyzates from unprocessed whole and bioprocessed (108 h) common beans had IC50 [concentration needed to inhibit 50% the activity of angiotens.n converting enzyme (ACE)] of 79.2 and 0.0117 μg/mL, respectively. The ssB is an efective strategy to improve the TPC of common beans for enhanced functionality with improved antioxidant activity and antihypertensive potential.

In this article, the analysis of Tsallis holographic dark energy(which turns into holographic dark energy for a particular choice of positive non-additivity parameter δ) in modified f(T, B) gravity with the validity of thermodynamics and energy conditions for a homogeneous and isotropic FLRW Universe has been studied. The enlightenment of the field equation towards f(T,B)=αT^m+βB^n, made possible by the fact that the model is purely accelerating,corresponds to q=-0.54(Mamon and Das 2017 Eur. Phys.J.C 77 49). The generalized second law of thermodynamics is valid not only for the same temperature inside the horizon, but also for the apparent horizon for a change in temperature. The ess.ntial inspiration driving this article is to exhibit the applicability that the holographic dark energy achieved from standard Tsallis holographic dark energy and the components acquired from f(T, B) gravity are identical for the specific bounty of constants. The analysis of energy conditions confirms that the weak energy condition and the null energy condition are fulfilled throughout the expansion, while violation of the strong energy condition validates the accelerated expansion of the *** the expansion, the model becomes a quintess.nce dominated model. The dominant energy condition is.not observed initially when the model is filled with genuine baryonic matter,whereas it appears when the model is in the quintess.nce dominated era.

To understand the wild Oryza genome effect on photos.nthesis and its relation to total dry matter accumulation in an elite rice variety, a set of 40 stable introgression lines(ILs) BC_3F_8 derived from a cross of Oryza sativa(KMR3) × Oryza rufipogon(WR120) were grown under well watered conditions. Leaf gas exchange measurements and leaf chlorophyll estimates were conducted at the flowering stage. The results revealed significant variations in net photos.nthetic rate(Pn), transpiration rate(E), transpiration efficiency(Pn/E) and carboxylation efficiency(Pn/C_i). Pn showed significant positive correlation with E, stomatal conductance(g_s), Pn/C_i and total canopy dry matter. specific leaf area and leaf thickness were not significantly correlated with Pn. Thirty-seven out of 40 ILs showed higher Pn than KMR3 [11.28 μmol/(m^2·s)], and 20 ILs showed higher Pn than WR120 [15.08 μmol/(m^2·s)]. The line IL194 showed the highest Pn [21.62 μmol/(m^2·s)] with increased total canopy dry matter followed by lines IL381, IL106, IL363-12, IL198, IL86-18 and IL50, which exhibited Pn above 18.0 μmol/(m^2·s). The ILs with enhanced Pn are a potential source for developing rice varieties and hybrids with higher biomass and yield.
