Over the past decade, the Malaysian government has put its effort into various programmes to promote solar energy in the country. As for now, Large Scale Solar (LSS) is the biggest programme conducted by Sustainable Energy Development Authority (SEDA) and permitted by Energy Commission (EC). As the large-scale solar does not have any proper guideline, especially in development approval consideration, Johor land administrators have put telecommunication tower development as a benchmark in approving large-scale solar developments that use the Special Permit method. However, the Special Permit fee appears unfitting for the development. Thus, this paper aims to determine the Special Permit rate for large-scale solar development which are profitable to the stakeholders. Its drawback is particularly related to solar radiance, which is the key criterion of site selection to develop the most profitablesite. Selected respondents have been interviewed and the findings have led to a direction to standardise a legal framework for large-scale solar, especially in Johor.

The Impact

Abstract Background The prices of energy resources are important determinants of sustainable energy development, yet associated with significant unknowns. The estimates of the impact of prices of energy products in the domestic market (for domestic consumers) are rare—hence the importance and novelty of this research. Therefore, the main goal of the paper is to assess the impact of domestic prices of gasoline, gas, coal, and solar energy on sustainable and secure energy future. Methods The research includes 14 countries (of which 7 are developed and 7 are developing countries) and a period of 5 years (2014–2018). The model also includes discrete variables: level of development (developing or developed), and the fact as to whether the country is an energy exporter or not. For the purposes of analysis, the following elements were used: Panel Data Analysis, Linear regression (with random and fixed effects), Durbin–Wu–Hausman test, and Honda test, with the use of R-studio software for statistical computing. Results The research showed that the biggest negative impact on energy sustainability was recorded by an increase in the price of coal and the smallest one by an increase in the price of solar energy. An increase in the price of gasoline has a positive impact, while an increase in the price of gas has no impact. The basic methodological result showed that the fixed effects linear model is more accurate than the random effect model. Conclusions The results of the paper, important as a sustainable energy policy recommendation, showed that the impact of changes in energy product prices is significantly greater in developing countries, but that the status of the country as an energy exporter has no significance. In addition, the paper points to the need to intensify the research on the assessment of the impact of energy product prices for domestic consumers on their ability to pay that price, because with a certain (so far undefined) increase in energy product prices, a certain group of domestic consumers moves into a category that is not in line with sustainable energy development and is extremely undesirable in every respect—energy poverty.

Abstract Planned efforts to probe the largest observable distance scales in future cosmological surveys are motivated by a desire to detect relic correlations left over from inflation, and the possibility of constraining novel gravitational phenomena beyond General Relativity (GR). On such large scales, the usual Newtonian approaches to modelling summary statistics like the power spectrum and bispectrum are insufficient, and we must consider a fully relativistic and gauge-independent treatment of observables such as galaxy number counts in order to avoid subtle biases, e.g. in the determination of the fNL parameter. In this work, we present an initial application of an analysis pipeline capable of accurately modelling and recovering relativistic spectra and correlation functions. As a proof of concept, we focus on the non-zero dipole of the redshift-space power spectrum that arises in the cross-correlation of different mass bins of dark matter halos, using strictly gauge-independent observable quantities evaluated on the past light cone of a fully relativistic N-body simulation in a redshift bin 1.7 ≤ z ≤ 2.9. We pay particular attention to the correct estimation of power spectrum multipoles, comparing different methods of accounting for complications such as the survey geometry (window function) and evolution/bias effects on the past light cone, and discuss how our results compare with previous attempts at extracting novel GR signatures from relativistic simulations.

The hydro-photovoltaic complementarity is an important operation mode to promote the grid-connected absorption, and one of the main directions of solar energy development and utilization in the future. The paper expounds the principle of hydro-photovoltaic complementarity and the influence of the installed ratio on economy, also summarizes and analyzes the research results of hydro-photovoltaic complementary system operation scheduling methods. In view of the uncertainty of hydro-photovoltaic complementary generation, the paper proposes several suggestions and expectations for the study of hydro-photovoltaic complementarity, to provide ideas for improve the economy and reliability of short-term and large-scale hydro-photovoltaic complementary operation.

Solar photovoltaic (PV) energy technology can play a key role in decreasing the amount of carbon emissions associated with electrical energy production, while also providing an economically justifiable alternative to fossil fuel production. Solar energy technology is also extremely flexible in terms of the size and siting of technological development. Large scale PV farms, however, require access to large tracts of land, which can create community-scale conflict over siting solar energy development projects. While previous scholarship offers frameworks for understanding the mechanisms at play in socio-technological system transitions, including the renewable energy transition, those frameworks fail to center community priorities, values, and concerns, and therefore often do not provide an effective means of addressing community conflict over solar siting. This paper provides a conceptual exploration of how a proposed framework can guide decision making for solar development across multiple scales and settings, while also illuminating the potential barriers and bottlenecks that may limit the potential of solar energy development to occur in scales and forms that receive community acceptance and at the pace necessary to address the greenhouse gas emissions currently contributing to the rapidly changing global climate.

MicroRNAs (miRs) are small single-stranded noncoding RNA that function in RNA silencing and post-transcriptional regulation of gene expression. An increasing number of studies have shown that miRs play an important role in tumorigenesis, and understanding the regulatory mechanism of miRs in this gene regulatory network will help elucidate the complex biological processes at play during malignancy. Despite advances, determination of miR–target interactions (MTIs) and identification of functional modules composed of miRs and their specific targets remain a challenge. A large amount of data generated by high-throughput methods from various sources are available to investigate MTIs. The development of data-driven tools to harness these multi-dimensional data has resulted in significant progress over the past decade. In parallel, large-scale cancer genomic projects are allowing new insights into the commonalities and disparities of miR–target regulation across cancers. In the first half of this review, we explore methods for identification of pairwise MTIs, and in the second half, we explore computational tools for discovery of miR-regulatory modules in a cancer-specific and pan-cancer context. We highlight strengths and limitations of each of these tools as a practical guide for the computational biologists.

Background: Progressive degradation of the environment due to the intervention of humans in the natural processes brought into light the need and the concept of sustainable development. The three pillars of sustainable development are Economic, Social, and Environmental. Sustainability has become one of the important tools to overcome the threats and is the dire need of the hour. This paper illustrates the detailed concept of Space-based solar power (SBSP) which defines the collection of solar energy in outer space and directing it towards the earth using electromagnetic waves. The edge of collecting solar power from space and not by the conventional methods include the strong collection rate and improved collection period. This is mainly because of the absence of the earth’s atmosphere that consists of a lot of external impurities and the decreased effects of reflection and absorption on solar energy on its way to earth. Objective: To put forward the importance of the use of space-based solar power system in India and to establish how space-based solar power is one of the answers of sustainable energy development for a better future for the country. Method: The study is based on secondary data. The findings indicate the need for sustainable energy development and the effective use of space-based solar power which would answer to the never-ending demands of human beings. Result: The article also delineates the opportunities of space-based solar power as well as the challenges that might be faced while building the system. Conclusion: The paper is a descriptive and conceptual study which illustrates SBSP as an innovative and important breakthrough in the field of science and one of the most important topics of discussion that needs to be addressed. The paper suggests the need for conducting more study on the topic and development of projects to measure its feasibility in the future, in terms of Indian context.

AbstractPrecise measurements of heliographic position of solar filaments were used for determination of the proper motion of solar filaments on the time-scale of days. The filaments have a tendency to make a shaking or waving of the external structure and to make a general movement of whole filament body, coinciding with the transport of the magnetic flux in the photosphere. The velocity scatter of individual measured points is about one order higher than the accuracy of measurements.
