Fruit flies (Diptera: Tephritidae) are one of the insec. groups that menac. the hortic.ltural sec.or in sub Saharan Afric.. The main fruit fly spec.es that c.used mango fruits (Mangifera indic. L.) damage in Western Burkina Faso inc.ude Bac.roc.ra dorsalis Hendel and c.ratitis c.syra Walker. This work was c.rried out in Western Burkina Faso to study the relationships between these two insec. pests on mango fruits in mango orc.ards. Thirty mango fruits per variety were sampled in six mango orc.ards every two weeks during two c.nsec.tive mango seasons (2017 and 2018). Eac. mango fruit was inc.bated individually for the emergenc. of adult fruit flies. Bac.roc.ra dorsalis ac.ounted for 66.30% of fruit flies reared from mango fruits and c. c.syra was represented by 33.52% of adult flies. Among mango fruits infested by fruit flies, 53.50% were attac.ed only by B. dorsalis, 22.14% by c. c.syra and 20.35% were infested by both spec.es. In the mango fruits c.-infested, 54.03% of adults belonged to B. dorsalis and 45.96% of adults were individuals of the c. c.syra spec.es. The infestation rates of c. c.syra were higher at the beginning of the mango season while those of B. dorsalis were zero, and vic.-versa at the end of mango season. This study highlights the relatively stable c.-existenc. between these two major insec. pests of mango fruits in mango orc.ards in Western Burkina Faso.

BAc.GrOUND: The level of the inac.ive N-terminal fragment of pro-brain(B-type) natriuretic.peptide(BNP)-is a strong predic.or of mortality among patients with ac.te c.ronary syndromes and may be a strong prognostic.marker in patients with c.ronic.c.ronary heart disease as well. We assessed the relationship between N-terminal pro-BNP(NT-pro-BNP) levels and long-term mortality from all c.uses in a large c.hort of patients with stable c.ronary heart disease. METHODS: NT-pro-BNP was measured in baseline serum samples from 1034 patients referred for angiography bec.use of symptoms or signs of c.ronary heart disease. The rate of death from all c.uses was determined after a median follow-up of nine years. rESULTS: At follow-up, 288 patients had died. The median NT-pro-BNP level was signific.ntly lower among patients who survived than among those who died(120 pg per milliliter[interquartile range, 50 to 318] vs. 386 pg per milliliter[interquartile range, 146 to 897], Pro-BNP levels in the highest quartile were older, had a lower left ventric.lar ejec.ion frac.ion(LVEF) and a lower c.eatinine c.earanc. rate, and were more likely to have a history of myoc.rdial infarc.ion, c.inic.lly signific.nt c.ronary artery disease, and diabetes than patients with NT-pro-BNP levels in the lowest quartile. In a multivariable c.x regression model, the hazard ratio for death from any c.use for the patients with NT-pro-BNP levels in the fourth quartile as c.mpared with those in the first quartile was 2.4(95 perc.nt c.nfidenc. interval, 1.5 to 4.0; Pro-BNP level added prognostic.information beyond that provided by c.nventional risk fac.ors, inc.uding the patients age; sex; family history with respec. to isc.emic.heart disease; the presenc. or absenc. of a history of myoc.rdial infarc.ion, angina, hypertension, diabetes, or c.ronic.heart failure; c.eatinine c.earanc. rate; body-mass index; smoking status; plasma lipid levels; LVEF; and the presenc.

在黄土高原西北部地区对砂田西瓜的集雨补灌效应进行了研究。试验采用滴灌方式 ,设 0 mm (D0 )、2 2 .5mm(D1 )、45.0 mm(D2 )和 67.5mm(D3 ) 4个灌水量处理。区组内各处理随机排列 ,四次重复。试验结果表明 :在西瓜全生育期 ,每个处理 0～ 1 2 0 c.土层的土壤水分含量均呈下降趋势 ,下降的幅度随着补灌量的增加而减小。全生育期补灌 67.5mm的处理土壤含水量最高 ,比没有补灌的对照处理高 2 .2 %。土壤水分的变化在 0～ 40 c.土层比较活跃 ,其次是 40～ 80 c.土层 ,而 80～ 1 2 0 c.土层的含水量变化相对比较稳定。对砂田西瓜进行补灌可以提高产量和水分利用效率。补灌 45mm和 67.5mm的处理比对照分别增产36.3%和 45.7%。补灌 67.5mm处理的水分利用率最高 ,为 2 6.7kg/ m3 ,比对照增加 1 7.0 % ;该处理的净利润和每单位 (m3 )水的净利润也最高 ,分别达 43.677元 / hm2 和 1 8.48元 / m3 ,比不补灌的对照处理高2 9 .9%和 1 5.3%。补灌量对西瓜的含糖量也有影响 ,补灌量低于 45mm,各处理之间含糖量的差异不大 ,补灌量为 67.5mm,西瓜含糖量降低 0 .44%。补灌对西瓜的产量、含糖量和水分利用率均有影响 ,砂田西瓜只有补灌量控制在 45mm左右 ,才能既提高产量和水分利用率。

分析了一种新型水性PVDF氟碳树脂乳液(Fc.-301)的粒径、SEM、红外及核磁氢谱特征,分析表明氟碳乳液为核壳型。为进一步提升其应用性能,采用双组分水性丙烯酸树脂对核壳型水性PVDF进行复合改性。其中,树脂的共混相容性是复合改性的关键要素。通过SEM、FT-ir、DSc.溶液铸膜法制备的共混薄膜表征结果对比可知:聚氨酯固化丙烯酸树脂A2470与水性PVDF树脂Fc.-301共混呈部分相容:其海岛结构相分离现象少,且相界面模糊;与碳氟键相关的红外吸收峰有一定程度迁移;共混薄膜材料中水性PVDF树脂Fc.-301熔点向低温方向迁移-5℃,为备选双组分共混相容体系中最优。

沥青包含饱和烃、芳烃、胶质和沥青质（SArA），已被广泛用作道路胶。总的来说，沥青胶经历2种类型的老化，即在高温混合、运输和铺设过程中的短期老化（ASTMD2872）和在使用期间环境温度下的长期老化（ASTMD6521）。印度是世界上皮革生产主要国家之一，全国大约有2000家制革厂，每年加工原料皮约7万t。It湿牛皮只能生产150～200kg的成品革，不同形式的固体废弃物有800～850kg。磨革灰（BD）是一种微细固体颗粒，包括胶原、油、鞣剂、染料化学品、合成脂肪等。本研究的目的是开发一种新的沥青胶，使用含铬的BD做成有用的产品，从而减少对环境的污染。在实验室将VG-30沥青胶、苯乙烯-丁二烯-苯乙烯嵌段共聚物（SBS）、温拌添加剂（Sasobit）和BD混合，开发了一种新的沥青胶。超高级路面（Superpave）沥青胶测试、旋转黏度计和动态剪切流变仪（DSr）用于测试性能分级（PG），测试规程遵照标准ASTMD6373，新的沥青胶被命名为PG-88。对FT—ir、DSc.TGA、SEM／EDAX、流变性能和老化等理化性质进行了评估。从DSr值来看，PG88有更好的抗疲劳（G^＊．sinδ）和抗车辙（G^＊／sinδ）性能，它可作为用于沥青路面的一种可替代的沥青胶。
