The main goal of this study is to evaluate the impact of restrictive measures introduced in connection with COVID-19 on consumption in renewable energy markets. The study will be based on the hypothesis that similar changes in human behavior can be expected in the future with the further spread of COVID-19 and/or the introduction of additional quarantine measures around the world. The analysis also yielded additional results. The strongest reductions in energy generation occurred in countries with a high percentage (more than 80%) of urban population (Brazil, USA, the United Kingdom and Germany). This study uses two models created with the Keras Long Short-Term Memory (Keras LSTM) Model, and 76 and 10 parameters are involved. This article suggests that various restrictive strategies reduced the sustainable demand for renewable energy and led to a drop in economic growth, slowing the growth of COVID-19 infections in 2020. It is unknown to what extent the observed slowdown in the spread from March 2020 to September 2020 due to the policy’s impact and not the interaction between the virus and the external environment. All renewable energy producers decreased the volume of renewable energy market supply in 2020 (except China).

Presently all world tendencies of energy are directed on the use and combining of renewable energy sources. Combining of a few renewable energy sources and not renewable results in partial energyindependence. In this work the laboratory setting was investigational on cooling and heating of water.During an experiment principles of Carnot were incorporated, hydrodynamics, recurrent-forward and dynamic compression of gases and many other. The association of a few renewable energy systems offered, here it is evidently rotined on charts, how many sources must be involved for work of the experimental setting. Statements were taken at the different experimental setting work terms for this purpose it was equipped plenty of sensors. Burn-time, pressure, temperature on the different areas of setting controlled remotedly, through mobile application.For theconstructions and estimation of testimonies mathematical model collection adequacy from sensors changes depending on the temperature indexes of external environment, that requires more detailed supervisions depending on time of year and desired temperature in an apartment, therefore and may need for this research more than year.The conducted experiments allowed to get the approximated information for the construction of pressure festering dependences charts from temperatures: exit from a compressor, from a capillary and, directly in a reservoir with a liquid, and similarly pressure from time of action. A research result was become by the built pressure dependences charts from temperatures on four basic areas of setting. For the estimation of testimonies mathematical model collection adequacy from sensors changes depending on the temperature indexes of external environment, that requires more detailed supervisions depending on time of year and desired temperature in an apartment, therefore and may need for this research more than year.Charts are similarly resulted showing, that with each necessary subsequent start, there are less time for achievement of maximal value of pressure in the system is need. Findings enable to build a mathematical model for the further improvement of setting.

Literature has indicated that factors such as--the external environment, cost saving mechanisms, user attitude and company size--may have an effect on the implementation of activity-based costing (ABC). Furthermore, literature has revealed that there is still lack of research on the effect of these factors on the implementation of ABC among small and medium sized enterprises (SMEs) in Malaysia. As such the aim of this research is to test the relationships of these factors on the implementation of ABC among SMEs in Malaysia with the aim of contributing to existing research on the ABC system in the area of management accounting. A total of 200 respondents participated in this research. The results of the study revealed that all four factors; the external environment, cost saving mechanisms, user attitude and company size have significant relationships with the implementation of ABC among SMEs in Malaysia.

Microprobe analysis of biological tissue is now in the end phase of transition from instrumental and technique development to applications pertinent to questions of physiological relevance. The promise,implicit in early investigative efforts, is being fulfilled to an extent much greater than many had predicted. It would thus seem appropriate to briefly report studies exemplifying this, ∿. In general, the distributions of ions in tissue in a preselected physiological state produced by variations in the external environment is of importance in elucidating the mechanisms of exchange and regulation of these ions.

Periplasm of bacteria is the space outside the permeability barrier of plasma membrane but enclosed by the cell wall. The contents of this special milieu exterior could be regulated by the plasma membrane from the internal, and by the cell wall from the external environment of the cell. Unlike the gram-negative organism, the presence of this space in gram-positive bacteria is still controversial because it cannot be clearly demonstrated. We have shown the importance of some periplasmic bodies in the secretion of penicillinase from Bacillus licheniformis.In negatively stained specimens prepared by a modified technique (Figs. 1 and 2), periplasmic space (PS) contained two kinds of structures: (i) fibrils (F, 100 Å) running perpendicular to the cell wall from the protoplast and (ii) an array of vesicles of various sizes (V), which seem to have evaginated from the protoplast.
