Red Study Greenway Route Selection at County Scale: A Case Study of Ji’an County, Jiangxi Province, China

Using multi-source data like remote sensing images,resource point coordinates,road networks and land type,a suitability assessment system for red study greenway route selection is constructed with red study resource layer,traffic condition layer,ecological condition layer,and service radius layer as the selection elements.Analytic Hierarchy Process(AHP)and Delphi method aree used to determine the selection factors and weight allocation of each element,and the single factor evaluation and multi factor overlaying analysis are used to accurately identify suitable selection corridors.The potential position is determined based on the lowest cost path.Finally,the final red study greenway is obtained through manual optimization based on the current situation of the road network.The analysis results show that the areas with the highest suitability were those with the richest distribution of first,second,and third level red study resources.An effective connection of red resource points and various elements helps to enhance the competitiveness of red study tours in Ji’an County,providing a realistic path for selecting study greenways for cities rich in red resources.

Study Finds More Reasons to Drink Red Wine

我是一个滴酒不沾的深圳人。读了此文,特地去买了一瓶红葡萄酒,日呷三口。 早有耳闻:现在流行喝红葡萄酒。红葡萄酒对健康有益。当我在MondayAugust 3 1998的“网”上读到此文时,如获至宝。今将此文加注,通过Email发给贵刊主编,望能借《科技英语学习》一隅,发表此文。让更多的读者能享用此信息。 红葡萄酒之“功”在于: red wine(红葡萄酒). as opposed to other forms of alcohol, can protect againstheart disease. 英国研究人员的工作真可谓认真过细！他们把试验的关键的成分(polyphenols,多酚)分为三种形式,其试验结果是。 Levels of the polyphenols were elevated by 38 percent wlth red wine, 28 percentwith capsules and 27 percent when the red wine polyphenols were dissolved in whitewine. 细心的读者肯定不会放过本文的另外两句有参考价值的话; 1. Several studies have shown that a moderate intake of any alcohol, not just redwine. can help protect against heart disease and perhaps cancer. 2. Green tea is also known to contain polyphenols, as does black tea.

Synthesis of malachite@clay nanocomposite for rapid scavenging of cationic and anionic dyes from synthetic wastewater

Synthesis of malachite@clay nanocomposite was successfully carried out for the removal of cationic（Methylene Blue,MB） and anionic dyes（Congo Red,CR） from synthetic wastewater.Nanocomposite was characterized by TEM,SEM,FT-IR,EDS analysis and zeta potential.TEM analysis indicated that the particle diameter of nanocomposite was in the range of 14 to23 nm.Various important parameters viz.contact time,concentration of dyes,nanocomposite dosage,temperature and solution pH were optimized to achieve maximum adsorption capacity.In the case of MB,removal decreased from 99.82%to 93.67%while for CR,removal decreased from 88.55%to 75.69%on increasing dye concentration from 100 to 450 mg/L.pH study confirmed the higher removal of CR in acidic range while MB removal was higher in alkaline range.Kinetic study revealed the applicability of pseudo-second-order model for the adsorption of both dyes.Negative values of AG0 for both systems suggested the feasibility of dye removal and support for spontaneous adsorption of CR and MB on nanocomposite.Nanocomposite showed 277.77 and 238.09 mg/g Langmuir adsorption capacity for MB and CR respectively.Desorption of dyes from the dye loaded nanocomposite was easily carried out with acetone.The results indicate that the prepared malachite@clay nanocomposite is an efficient adsorbent with high adsorption capacity for the aforementioned dyes.
