Assessing carrying capacity of regional water resources in karst areas, southwest China: a case studySpringer Science and Business Media LLC - Tập 25 - Trang 15139-15162 - 2022
Tao Peng, Zhiyuan Jin, Lujun Xiao
Water resource is an important and irreplaceable resource for human society.
With the increasing shortage of water resources, the study of water resources
carrying capacity (WRCC) has become a key and hot issue in the field of water
resources science. In this study, a typical karst area (Guiyang) is selected as
the research object. And two concepts of WRCC are proposed to assess scales of

Impact of government intervention to maize efficiency at farmer’s level across time: a robust evidence in Northern VietnamSpringer Science and Business Media LLC - Tập 23 - Trang 2038-2061 - 2020
Nguyen To-The, Tuan Nguyen-Anh
The Vietnamese government has already legislated many agricultural policies to
improve farmers’ performance. In particular, the extension programme aims to
enhance technical efficiencies of targeted farmers. Besides, negative
environmental effects of chemical pesticides and climate change on agricultural
production efficiency have been proved in many recent studies. Therefore, the
northern mountai... hiện toàn bộ
Environment-friendly recycled asphalt pavement design for road maintenance applicationsSpringer Science and Business Media LLC - Tập 24 - Trang 14210-14234 - 2022
Sharaf AlKheder
Potholes are one of the most common road distresses in Kuwait especially after
winter season in 2018. Pavement deterioration rate significantly increases as
the pavement exposes to moisture. Paving road requires using high-quality
materials. This paper aims to investigate the feasibility of using recycled
asphalt pavement in hot mix asphalt (HMA) design. Questionnaires and a series of
laboratory t... hiện toàn bộ
Effects of the energy transition on China’s economic sustainabilitySpringer Science and Business Media LLC - - Trang 1-25 - 2023
Wei Wei, Zanxin Wang
Optimizing energy transition policies while considering economic sustainability
has been a crucial research topic. However, it is difficult to build a
quantitative model to identify the relationship between energy transition and
the regime-switching process from an “unsustainable regime” to a “sustainable
regime.” Here, we construct a dynamic stochastic general equilibrium model
embedded in econom... hiện toàn bộ
Implementation of self-regulating controller for integrating DFIG-based grid system with load interruptionSpringer Science and Business Media LLC - - 2021
A. Santhi Mary Antony, D. Godwin Immanuel
Nowadays, wind energy is a booming renewable energy source due to its
characteristics like zero emission, clean and easy availability. The rotor and
grid side converter in WECS is articulated by a DC link component. The capacitor
plays the role of DC link component. The DC link in WECS is replaced by a
Reboost converter. The Reboost converter is a unidirectional DC-DC converter
performing boosting... hiện toàn bộ
Greenbelt conservation as a component of ecosystem, ecological benefits and management services: evidence from Peshawar City, PakistanSpringer Science and Business Media LLC - Tập 24 - Trang 11424-11448 - 2021
Abdul Basit, Noor Ul Amin, Syed Tanveer Shah, Imran Ahmad
Conservation of greenbelts is the most enduringly successful and popular basic
need for today to protect green land, preserve ecological landscape and open
green spaces or gardens in urban fringes. Developing countries like Pakistan
need to generate a wide range of strategic policies for the limitation of urban
sprawl and construction of green structures to achieve sustainable green
development. T... hiện toàn bộ
Modeling of gasification process of Indian coal in perspective of underground coal gasification (UCG)Springer Science and Business Media LLC - Tập 22 - Trang 6171-6186 - 2019
Ramesh Naidu Mandapati, Praveen Ghodke
In the present study, the steam gasification of Indian coal and its
demineralized coal were investigated in a specially designed fixed-bed reactor,
to determine the intrinsic kinetics parameters with optimum operating
temperature and partial pressures of steam in the perspective of underground
coal gasification (UCG). The gasification reactivity of a chosen coal was higher
compared to the deminera... hiện toàn bộ
