The Relevance of Perception in Landscape Framework
The relationship with bicycle infrastructure is lacking in current empirical research on user perceptions, which, on the contrary, studies emphasize aesthetic quality or visual surveys.  As the cycling infrastructure is a key area for commuting, shopping, entertainment, and recreation in urban communities, a thorough understanding of users’ perceptions of the environment is needed. Landscape and bicycle infrastructure cause a different perception as psychological factors interact based on the function of use. Bicycle spaces are small, enclosed, and lack contact with nature because they are often designed with inappropriate criteria. The bicycle infrastructure is seen in full harmony and potential with the landscape if there is contact with nature. These physical elements affect the sorts of landscape- or user-oriented policies and procedures that attempt to increase user satisfaction levels for the former and landscape promotion for the latter, in addition to cultural and psychological considerations.

Carbon Dioxide Separation Technologies
Carbon dioxide (CO2) emissions from burning fossil fuels play a crucial role in global warming/climate change. The effective removal of CO2 from the point sources or atmosphere (CO2 capture), its conversion to value-added products (CO2 utilization), and long-term geological storage, or CO2 sequestration, has captured the attention of several researchers and policymakers.

Recent Trends in Foliar Nanofertilizers
It is estimated that 40 to 70 per cent, 80 to 90 per cent and 50 to 90 per cent of the conventional macronutrients N, P and K applied to soil are lost, respectively, resulting in considerable resource losses. Compared with traditional fertilizers, nano fertilizers have small volume (1-100 nm) and high specific surface area, and have the advantages of controlled release, high nutrient utilization, low cost and relatively small environmental pollution. The application of nanofertilizers is an emerging area of agricultural research and is an attractive and economical alternative to traditional fertilizers that could sustainably increase global food productivity. Foliar fertilization is a popular method to meet the needs of higher plants. Due to the small amount of leaf application, nutrient absorption is faster than the soil, and environmental pollution is relatively small, so it is more popular in plants. It can be seen that nano-fertilizer and foliar fertilization are the focus of attention at present, and the study on the foliar application of nano-fertilizer is not as extensive as that of soil application.

Carbon Sequestration in Soil
The agroforestry systems with a high potential for carbon (C) sequestration are those degraded by poor management strategies. Studies on changes in soil C status in these ecosystems mostly take into account labile C pools. Labile and stable soil organic matter (SOM) fractions are affected by soil management and land-use changes. Stable C pools are essential to understanding effects of land-use on soil C storage in the long term.

Meteorological Conditions on Riverbed Dust Aerosol in Taiwan
Extremely high concentrations of dust particles are occasionally generated from the riverbeds of Taiwan, affecting the visibility and traffic safety of the local and nearby areas. The condition is most severe during the winter monsoon when surface wind is strong.

ROS and Antioxidants in Halophytes
Reactive oxygen species (ROS) are excited or partially reduced forms of atmospheric oxygen, which are continuously produced during aerobic metabolism like many physiochemical processes operating throughout seed life. Previously, it was believed that ROS are merely cytotoxic molecules, however, now it has been established that they perform numerous beneficial functions in plants including many critical roles in seed physiology. ROS facilitate seed germination via cell wall loosening, endosperm weakening, signaling, and decreasing abscisic acid (ABA) levels. Most of the existing knowledge about ROS homeostasis and functions is based on the seeds of common plants or model ones.

Anaerobic Co-Digestion
The anaerobic mono-digestion treatment of organic waste can be challenging due to nutrient imbalances and a lack of microbial diversity. However, anaerobic co-digestion has been shown to effectively address both challenges without the need for additives.

Agricultural Eco-Efficiency：Challenges and Progress
The research on agricultural eco-efficiency has become an important point to deeply understand the interaction between ecological and environmental conditions and socio-economic factors as well as realize the coordinated development of agricultural economic development and environmental protection. (1) Background: This paper attempts to provide scientific support for the healthy and stable development of the agricultural economy and the sustainable development of ecological agriculture. (2) Methods: From a comprehensive perspective, this paper systematically analyze the overall situation, development trend, key fields, and hot fields of agricultural eco-efficiency in the past two decades. It consists of two complementary parts, including systematic quantitative literature review (based on CiteSpace) and traditional literature review. (3) Results: Agricultural eco-efficiency has evolved significantly with the popularization of agricultural machinery and the wide application of science and technology in the field of agricultural ecology. Its future development relies on the advances in our knowledge on theories and hypothesis, evaluation methods, impact on “socio-economic ecological” system, and drivers and regulation of agricultural eco-efficiency. For each of these fields, we find that challenges still exist. At present, the quantitative methods and index selection are not unified. We should deeply analyze the internal and external driving force of the development and change of ecological efficiency by constructing a complete theoretical framework for the research of agricultural ecological efficiency. At the same time, new technologies and methods are needed to evaluate agricultural eco-efficiency, and a balanced consensus between the improvement of agricultural eco-efficiency and the improvement of the ecological environment should be formed through empirical research.

Methodological Improvement in SF6 of Malaysia's National Inventory
Sulfur hexafluoride (SF6) gas is one of the high global warming potential (GWP) gases regulated under the Kyoto Protocol. In Malaysia’s Biennial Update Report 3, the Revised 1996 Intergovernmental Panel on Climate Change Guidelines were followed to estimate the SF6 emissions in the country, including the time series from 1990 to 2016. The majority of SF6 emissions originate from the use of this gas in electrical equipment, where it is predominantly used in transmission switch gears, which have increased rapidly because of increasing electricity demand. SF6 gas plays a significant role in greenhouse gas emissions in Malaysia because this gas has a higher GWP than carbon dioxide.
