Essential oils can have an impact on behavioural responses of cigarette beetle (Lasioderma serricorne). In this study, we provide evidence that some chemical compounds in essential oil of tobacco (Nicotiana tabacum) leaves, which were subjected to hydrodistillation and extracted with n-hexane, can strongly...

Medium and long term load forecasting is important for power system planning and construction. Affected by the New Economy normal and other relevant factors, various regions of China have entered a new period of economic development mode and industrial structure changing. Load structure and load growth...

Based on the response characteristics, reactive power sources are divided into fast sources and slow sources. According to the thought of reactive power source buses partition and load buses merging, this paper proposed a power network secondary partition method based on the response characteristics...

The use of electrical devices has been increased tremendously around the world. Portable nickel-cadmium (Ni-Cd) batteries have been used in electronic products for many decades and have resulted in the generation of huge amounts of waste batteries. The battery disposal in municipal solid waste has become...

A series of transition metal-doped MOF-5 materials (M-MOF-5, M=Cu, Co or Mn) have been prepared by hydrothermal methodology. The structures of M-MOF-5 were confirmed by powder X-ray diffraction (XRD) and Fourier transform infrared (FT-IR). The adsorptive performance of thiophenic compounds (T, BT and...

As the pillar industry of the national economy, electric power has important influence on promoting the development of national macroeconomic. Along with the issuance of "No.9 Document" in 2015, China's power industry reform has entered a critical period. Based on the prosperity indexes analysis and...

An exploratory study of combinations among environment behavior science, space syntax and interactive activities on campus is presented. To answer the reason why the public spaces on campus could not be used effectively as expected, the study focuses on the potential relationship between spatial configurations...

The water diversion-transportation-drainage-return had become the dominant regional hydrological processes in Qingtongxia irrigation area. For the reason of systematically mastering water cycle rules of Qingtongxia irrigation area, this study chose MIKE SHE distributed hydrological model with physical...

The position of the tap switch is the main measure to adjust voltage, unfortunately, most of the position of tap switch was unknown because there were no information of the position on distribution transformer. This paper proposed a novel method to detect the position of the tap switch, the voltage and...

To solve the problem of utilization of typical waste resources in Daqing, the rich corn stalk in Daqing and the Daqing oilfield waste sludge were respectively selected as major and auxiliary raw. The influence of sludge proportion, moisture content of mixed materials and molding pressure on quality characteristics...

The energy saving and emission reduction of public transportation enterprises is very important. What factors affect these jobs? Through investigating 7 cities of different scale and different places, we can know actual data. By comparing the data of different cities, we can analyze the influence of...

To examine the effects of nitrogen and reclaimed municipal wastewater(RMW) irrigation on fruit quality of greenhouse tomato and soil nitrogen utilization, field experiments were carried out. Root-layer mineral nitrogen, total nitrogen, tomato yield, nitrogen in fruit, partial factor productivity from...

Karst immersion-waterlogging disaster is the unique natural disasters in karst area. It has the characteristics of periodicity and sudden. Generally, it mainly distributed in peak cluster depression, peak forest valley and Butte plain area. The main Influence factors including Rainfall condition, Karst...

Partial nitrification (PN) treatments on waste-brine were carried out in this study. Stable PN performance was obtained during continuous operation for 752 days, with a maximum nitrogen loading rate (NLR) of 3 kg-N m-3 day-1 and ammonium conversion rate (ACR) of 1.4 kgNm-3day-1. The ratios of NO2--N/...
