Effect of microalgae storage conditions on methane yields

Environmental Science and Pollution Research, 2018
During the last decade, a lot of research has been focused on identifying the methane yields achievable when using microalgae biomass (fresh and pretreated) as a substrate in anaerobic digestion. Encountered differences are frequently attributed to the different microalgae strains (cell walls and macromolecular profiles) or the different metabolic ...

Plastic spin and evolution of an anisotropic yield condition

International Journal of Mechanical Sciences, 2000
Abstract Isotropic and anisotropic hardening will be combined with plastic spin in order to describe the microstructural behaviour of a polycrystalline metal in terms of continuum mechanics. In the present paper emphasis is given to the experimental procedure, based on previous work by Boehler and Koss and applied in order to verify that approach ...

Aelotropic Yield Condition

1970
In current literature ad hoc semi-emperial laws are widely used for transition problems in applied Mathematics, Physics and Engineering Sciences. It is particularly true of elastic-plastic deformation for which a number of yield conditions have been employed [8].

Yield conditions for layered composites

International Journal of Solids and Structures, 1981
Abstract The continuum elasto-plastic theory of layered composites is presented. The composite consists of two elasto-ideal plastic constituents. The associated flow rule is assumed to be valid for both constituents. The starting point of the presented considerations is an elastic state described by structural relations, i.e.

Effect of Biochar on Maize Yield and Yield Components in Rainfed Conditions

SSRN Electronic Journal, 2018
To investigate the maize yield and nutrient concentration in its leaves as affected by biochar from different organic materials (wheat straw and sugarcane bagasse), a field experiment was conducted on maize crop during 2013 at koont research farm chakwal.

Conditions for High Yield in the Labeling of Hydrocarbons by Exchange

1965
This report presents the results of a series of experiments to study the exchange between D2O and D2 and some hydrocarbons. The purpose was to evaluate Co/Mo/S on Al2O3 as a catalyst for this exchange, and to determine optimum conditions for yield and minimum decomposition. It was also hoped that as a result of determining the deuterium distribution in

The effect of cultivars and weather conditions on yield and yield components of wheat

2021
Wheat is one of the most widespread cereals in the world and the second most dominant field crop in Croatia. The aim of this study was to determine the yield, yield components and some morphological properties of eight different cultivars of winter wheat. The research was conducted during the wheat vegetation 2018/2019 on the surfaces of the Faculty of

The Yield Condition of Crystalline Solids

1981
A brief account of some results pertaining to the yield are presented. Accordingly to thermostatics an equilibrium state is stable when the second variation of the energy is positive definite (δ 2 u> O) and unstable when it is indefinite (δ 2 u can take negative values for one or more variables). The onset of material instability occurs when the second

Morphology and Yield in Winter Wheat Grown in High Yielding Conditions

Crop Science, 1982
To reassess the relations of morphological characters and yield components in high yielding field conditions measurements were taken on a series of modern cultivars of winter wheat (Triticum aestivum L. em. Thell.) over 4 years. Morphological traits measured were leaf area, leaf dry weight, leaf area duration, specific weight of each of the three ...
