Despite these benefits, living roof coverage in China remains limited. To address the challenges in policy formulation, operational monitoring, and the absence of multi-scale retrofit strategies supported by robust assessment methods, this study develops a comprehensive evaluation framework. The framework integrates vector data, building age information, and point-of-interest(POI) data, and applies an optimized Prophet model to classify six major climate zones. This approach facilitates the selection of appropriate plant species and substrates while quantifying the potential for carbon sequestration and oxygen release. An assessment of 90 cities reveals approximately 1.3861 billion square meters of rooftop area suitable for green roof implementation, with an estimated annual carbon sequestration potential of 67.30 million tons and oxygen release of 30.36 million tons. Commercial buildings contribute significantly, comprising 65% of the total suitable area. Climate zones 2 and 3 exhibit the most favorable outcomes. The current study provides a reliable quantitative reference for evaluating the carbon sequestration and oxygen release capacities of green roofs and supports the formulation of effective retrofit policies.展开更多

Greene were sampled to measure the nutritional indices. The nutritional indices were also compared with common forage grass,and the development value of L. nodiflora as feed was analyzed. Compared with P. nodiflora,L. nodiflora had obvious fast-growing and high-yield abilities. The contents of crude fat,crude fiber,crude ash,lysine,vitamin C,Ca,and Fe in L. nodiflora were obviously higher than that in P. nodiflora,but the content of crude protein and total P in L. nodiflora were significantly lower than that in P. nodiflora. Compared with common forage feed ryegrass,alfalfa,millet straw and corn straw,L. nodiflora had higher contents of crude fat and crude ash and lower contents of crude fiber and crude protein. Therefore,L. nodiflora had higher development value as feed.展开更多

The Latin verse in 1579 by Anthony Munday follows acrostic English poems and may refer to his patron as ＂a lover of Pallas Athena＂ （the Spear-shaker of Greek mythology）. The Latin verse in Robert Greene＇s 1584 book may contain a Latin acrostic and appears to identify Cupid, the ＂winged Love,＂ as a companion of the same patron as Munday＇s from five years earlier. That Cupid trope appears similar to ＂the little love god＂ allusions to Cupid in several of Shakespeare＇s sonnets （e.g., #s 153 and 154）. More than these discussions, this article explores difficulties of translating from Latin into English, or vice versa, and the pitfalls which can occur.展开更多

When the vehicle is moving slower or faster than this ideal operating point the engine’s combustion cycle fails to properly burn the air/fuel mixture leading to considerably compromised engine performance and wastes fuel. Variable Valve Timing (VVT) is a solution developed to overcome this engine deficiency, dynamically altering the valve's opening and closing for optimal performance at any speed. The intension in this work is to contribute towards pursuing the development of variable valve timing (VVT) for improving the engine performance. This investigation covers the effect of exhaust valve opening (EVO), and closing (EVC) angle on engine performance and emissions. The aim is to optimize engine power and brake specific fuel consumption (BSFC) where the effect of engine speed has also been considered. Power, BMEP, BSFC, NO, and CO were calculated and presented to show the effect of varying valve timing on them for all the valve timing cases. The calculations of engine performance were carried out using the simulation and analysis engineering software: LOTUS”, and engine emissions were calculated using “ZINOX” program. Sensitivity analysis shows that the reduction of 10% of (EVO) angle gave a reduction of around 2.5% in power and volumetric efficiency, also a slight increase in nitrogen oxide (NO) and carbon monoxide (CO), while a 10% decrease in (EVC) causes around 1% improvement in Power. The effects of different (VVT) from the simulations are analyzed and compared with those in the reviewed literature.展开更多

Some countries have developed green building certification systems. Compared to other developed areas, Taiwan lags behind in green building construction and in response created its own certification for sub-tropical countries called Ecology, Energy Saving, Waste Reduction, and Health (EEWH). But what economic factors truly drive green building construction and quality? Our study sample analyzes 1355 Taiwan green building cases from 2000 to June 2018 to determine the influence of various economic, structural, and policy factors. Results suggest that while public ownership led to more green building certifications, private ownership led to a higher environment rating. Proper incentives are needed to further increase the ratings of public buildings and to expand the construction of highly rated private buildings, especially for small and medium sized buildings.展开更多
