Proteases with caspase 3-like activity participate in cell death during stress-induced microspore embryogenesis of Brassica napus

embryogenesis is induced by high temperature stress treatment of freshly isolated microspores, achieving a high percentage of haploid embryos ( 1 , 6 ). However, one of the limiting factors of embryogenesis induction and early embryogenic development is the fact that after the stress treatment some microspores do not respond to the induction and die, reducing microspore embryogenesis efficiency ( 8 , 9 , 10 , 11 ). Cell viability is one of the determinant factors through stress response, and implies activation of various signal cascades to promote a switch towards

Peripheral vein detection using electrical impedance method

Abstract

The electrical impedance method of peripheral vein detection is a novel approach, which offers the advantages of not being expensive and the capability of minimizing and reducing the difficulty of achieving intravenous access in many patients, especially pediatric and obese patients. The electrical impedance method of peripheral vein detection is based on the measurement of electrical impedance using the 4-electrode technique by applying a known alternating current of frequency 100 kHz and constant amplitude to a set of current electrodes and measuring the resulting surface potential at two separate electrodes. This paper presents the results of investigations to estimate the efficiency of this method.

Photosynthetic light reactions in Oryza sativa L. under Cd stress: Influence of iron, calcium, and zinc supplements

Abstract

Some mineral nutrients may help to alleviate cadmium stress in plants. Therefore, influence of Fe, Ca, and Zn supplements on photosynthesis light reactions under Cd stress studied in two Indian rice cultivars namely, MO-16 and MTU-7029 respectively. Exogenous application of both Fe and Ca ions helped to uphold quantum efficiency and linear electron transport during Cd stress. Also, recovery of biomass noticed during Cd treatment with Fe and Ca supplements. It was found that accumulation of carotenoids as well as non photochemical quenching enhances with Fe, Ca, and Zn supplements. Chlorophyll a/b ratio increased with Cd accumulation as a strategy to increase light harvest. Lipid peroxidation level was ascertained the highest during Cd plus Zn treatments. Above results point that both Fe and Ca ions supplements help to alleviate Cd stress on photosynthesis light reactions of rice plants.

Renewables as important energy source for Moldova

influence on biomass productivity ( 4 ). Also the long-term potential for energy crops is influenced by land availability, including restrictions imposed by water and nature protection, population diet, the energy crops type (species) influencing on biomass yield etc. The Republic of Moldova, being 85% dependent on energy imports, from 2012 started to develop the appropriate legislative framework to stimulate the use of renewable energy sources. Several institutions, including the Energy Efficiency Agency and the Energy Efficiency Fund, have been created for this

Contributions of biotechnology to meeting future food and environmental security needs

can enhance at least four aspects of securing our food supply in a sustainable manner ( 1 , 13 ). The availability of food for global consumers can be improved by increasing the efficiency and effectiveness of our primary food production systems, reducing waste during food processing and trade actions, improving access to food supplies through better transport and marketing systems to drive down food costs, improving the buying power of consumers, particularly in developing countries. Food utilisation can also be enhanced, by improving the nutrient status of food

The pre-processing stage As shown in Fig.1 , the pre-processing stage contains: firstly, the selection of space dimensions, however, 2D space dimension is preferred to simplify the model in order to reduce the running time and increase the efficiency of the model. Secondly, the selection of physics, the electric current module is preferred to simulate the applied

These steps are referred as the water line, while the usual aerated activated sludge mechanism as secondary treatment results in sludge to be managed in the sludge line. WWTPs are focusing on the water line as that delivers clean water which is the main performance and legal indicator; improvement of the sludge line by means of energy and cost efficiency, as well as its environmental performance is

An efficient and automatic ECG arrhythmia diagnosis system using DWT and HOS features and entropy- based feature selection procedure

extensively applied time–frequency technique [ 8 , 9 , 10 , 11 ]. The wavelet transform gives a high resolution in the frequency and time domains. High dimensionality of the feature space makes an increase in computational time and a decrease in classifycation accuracy. To build robust learning models, a subset of the relevant features should be determined. The main objectives of feature selection are making a faster and more efficient learning procedure, ameliorating the efficiency of classification and making a better understanding of the underlying process that

Bio-economy in Greece: Current trends and the road ahead

. Countries have already developed Bio-economy strategies which, however, differ sometimes considerably in range and content focus. (Global Bio-economy summit 2018 ( 16 ). In the past two years, seven more countries adopted dedicated Bio-economy policy strategies, mostly in Europe. In many countries, sub-regional Bio-economy strategies and policies have been developed in order to exploit local advantages ( 17 ). Greece does not have a specific National strategy on the Bio-economy yet, although the Greek government assigns a high priority to resource efficiency as well
