Age determination on monazite from Forefinger Point granulites, East Antarctica (Table 2.6-1)

Electron microprobe (EMP) dating on monazite in granulite- facies rocks from Forefinger Point, East Antarctica, yielded dominant ages of 500 Ma on matrix monazites.They are associated with secondary cordierite, biotite and sapphirine, formed during nearly isothermal decompression after the high P-T assemblages involving garnet, orthopyroxene and sillimanite. Older ages around 750-1000 Ma are detected in monazite cores and in monazite inclusions in garnet porphyroblast. Combining the available age data and the reaction textures, it becomes evident that the Forefinger Point granulites have been overprinted by a granulite-facies decompressional event of Pan-African age. Moreover, EMP monazite dating imply that the Forefinger Point granulites have experienced at least two stages of metamorphic evolution.

Obtenção de álcool alílico (PROP-2-EN-1-OL) a partir da glicerina derivada do biodiesel de óleo de mamona

In this work, biodiesel was produced from castor oil that was a byproduct glycerin. The molar ratio between oil and alcohol, as well as the use of (KOH) catalyst to provide the chemical reaction is based on literature. The best results were obtained using 1 mol of castor oil (260g) to 3 moles of methyl alcohol (138g), using 1.0% KOH as catalyst at a temperature of 260 ° C and shaken at 120 rpm. The oil used was commercially available, the process involves the reaction of transesterification of a vegetable oil with methyl alcohol. The product of this reaction is an ester, biodiesel being the main product and the glycerin by-product which has undergone treatment for use as raw material for the production of allyl alcohol. The great advantage of the use of glycerin to obtain allyl alcohol is that its use eliminates the large amount of waste of the biodiesel and various forms of insult to the environment. The reactions for the formation of allyl alcohol was conducted from formic acid and glycerin in a ratio 1/1, at a temperature of 260oC in a heater blanket, being sprayed by a spiral condenser for a period of 2 hours and the product obtained contains mostly the allylic alcohol .. The monitoring of reactions was performed by UV-Visible Spectrophotometer: FTIR Fourier transform, the analysis showed that these changes occur spectrometer indicating the formation of the product allylic alcohol (prop-2-en-1-ol) in the presence of water, This alcohol was appointed Alcohol GL. The absorption bands confirms that the reaction was observed in (υ C = C) 1470 -1600 cm -1 and (υ CO), 3610-3670 attributed to C = C groups and OH respectively. The thermal analysis was carried out in a thermogravimetric analyzer SDT Q600, where the mass and temperature are displayed against time, that allows checking the approximate rate of heating. The innovative methodology developed in the laboratory (LABTAM, UFRN), was able to treat the glycerine produced by transesterification of castor oil and used as raw material for production of allyl alcohol, with a yield of 80%, of alcohol, the same is of great importance in the manufacture of polymers, pharmaceuticals, organic compounds, herbicides, pesticides and other chemicals

八角科植物系统学研究 — 比较木材解剖学及花被片表皮比较形态学

本文回顾了八角科（Illiciaceae）的分类历史，对其现状进行了介绍，并提出了存在的一些问题，针对这些问题，我们对八角科及其近缘类群 [五味子科（Schisandraceae）和木兰科（Magnoliaceae）] 的木材解剖特征，以及对组成八角目(Illiciales)的八角科和五味子科的花被片表皮形态进行了研究，进一步确定了八角科在离生心皮类中的原始地位，且为其属的次级划分提供了更多的性状支持，更详尽地阐述了它与近缘类群间的系统学关系，确定了八角目的独立地位。 １　比较木材解剖学 在光学显微镜和扫描电子显微镜下，对八角科八角属（Illicium）2组19种1亚种43个材料、五味子科2属4种7个材料和木兰科1属3种4个材料的木材解剖结构进行了比较研究。 因八角科导管单独、多角形、密集、细长且具螺纹加厚，穿孔板梯状且细密，射线异形等特征，本文支持建立单属的八角科。在八角属内，由于八角组（Sect. Illicium）的导管分子密度较高和直径较窄，易损度为0.090，射线较高，而八角茴香组（Sect. Cymbostemon）的导管分子密度较低和直径较宽，易损度为0.194，射线较矮，因而本文支持将八角属分为八角组和八角茴香组，且八角组比八角茴香组原始。根据欧式距离，八角科与五味子科之间的相似性（d=4.690）比八角科与木兰科（d=4.899）之间的相似性大，本文支持建立八角目（Illiciales）。 2　花被片表皮比较形态学 在光学显微镜和扫描电子显微镜下，观察了八角科八角属2组11种20个样品、五味子科南五味子属（Kadsura）2亚属2组8种15个样品和五味子属（Schisandra）2亚属4组6种17个样品的花被片表皮形态特征。 首次报道了八角目2个科（八角科和五味子科）3个属（八角属、南五味子属和五味子属）植物花被片表皮细胞的形状、分泌细胞的形状及分布、气孔器的形状及分布、花被片表面的纹饰，在五味子科中发现2个新的性状（气孔对和环列型气孔）。 通过与八角目2个科3个属植物的叶表皮形态比较，发现花被片表皮气孔器外拱盖均为单层，与叶表皮气孔器外拱盖层数（常绿种类为双层和落叶种类为单层）之间没有相关性。通过对两性花、雌花和雄花花被片表皮观察，发现花被片表皮形态与花的性别之间没有相关性。通过对八角属、南五味子属和五味子属花被片表皮比较，发现五味子属花被片表皮形态比南五味子属花被片表皮形态表现出更多的衍生性状，南五味子属花被片表皮形态比八角属花被片表皮形态表现出更多的衍生性状;南五味子属花被片表皮形态与五味子属花被片表皮形态之间的相似性程度较大，与八角属花被片表皮形态之间的相似性程度较小，支持建立含南五味子属和五味子属的五味子科，支持建立只含八角属的八角科。

不同氮肥管理措施对草坪生长和无机氮淋洗的影响

本研究采用室外盆栽试验，模拟运动场坪床结构，研究不同氮肥种类、不同施氮频率、施氮和降雨时间间隔对草地早熟禾草坪质量、草坪生长和无机氮淋洗的影响，并探讨在北京地区气候条件下，草坪在不同氮肥管理措施下的氮素去向及环境风险。主要结论如下： 1. 氮肥种类对草坪质量和草坪生长有显著影响。试验前期（春季），草坪颜色和密度质量、草坪草生长速度和草屑全氮含量的排序为尿素 > CU3M（自研包膜尿素）> IBDU（进口缓释肥），而试验后期（秋季）则为CU3M = IBDU > 尿素。草坪合格颜色质量持续时间和成坪速度的排序为尿素 > CU3M > IBDU。在新建草坪选择缓释肥进行早春施肥时，应混施一定比例的速效肥。 2. 施氮频率对草坪外观质量评分、草坪生长速度、草屑总生物量、草屑全氮含量和根系分布状况有显著影响。U6处理的草坪合格颜色质量持续时间最长，增加施氮频率没有降低新建草坪生长速度和草屑全氮含量的波动幅度。 3. 夏季（6~8月）渗漏液体积占全年的比例最高，为75.0%~82.4%。新建草坪初期的淋洗风险较大，渗漏液硝态氮浓度在第1次超过10 mg N•L-1，尿素分6次施用可降低这次的渗漏液硝态氮浓度。在合理施氮量内，草坪成熟后的无机氮淋洗量很小，且草坪对雨水中的无机氮有吸收和过滤作用。 4. 春季施用氮肥的吸收利用率为48.0%~72.6%，草屑吸收量最高，占38.5%~48.7%，地上部吸收量占19.6%~22.1%，根系吸收量在7.3%以下。施肥处理的无机氮淋洗损失量仅为0.23~0.42 g N•m-2，与CK无显著差异，草地早熟禾12 g N•m-2的年施氮量对环境的风险很小。 5. 初秋施氮5 g N•m-2，可以保持草地早熟禾秋季的良好颜色和密度质量，草坪草氮素吸收利用率高达87.4%~99.7%，其中草屑带走量占24.3%~34.2%，地上部吸收量占43.3%~59.6%，根系吸收量占14.2%~19.1%。 6. 施氮和模拟降雨的时间间隔对渗漏液硝态氮浓度有显著影响，间隔6 d和9 d模拟降雨后的渗漏液硝态氮浓度最高，显著高于间隔3 d和12 d模拟降雨的结果。初秋合理施氮的渗漏液硝态氮浓度在1.0 mg N•L-1 以下，环境风险较小。

Effect Of Temperature On The Respiration Rate Of Meiofauna

The effect of temperature on respiration rate has been established, using Cartesian divers, for the meiofaunal sabellid polychaeteManayunkia aestuarina, the free-living nematodeSphaerolaimus hirsutus and the harpacticoid copepodTachidius discipes from a mudflat in the Lynher estuary, Cornwall, U.K. Over the temperature range normally experienced in the field, i.e. 5–20° C the size-compensated respiration rate (R c) was related to the temperature (T) in °C by the equation Log10 R c=-0.635+0.0339T forManayunkia, Log10 R c=0.180+0.0069T forSphaerolaimus and Log10 R c=-0.428+0.0337T forTachidius, being equivalent toQ 10 values of 2.19, 1.17 and 2.17 respectively. In order to derive the temperature response forManayunkia a relationship was first established between respiration rate and body size: Log10 R=0.05+0.75 Log10 V whereR=respiration in nl·O2·ind-1·h-1 andV=body volume in nl. TheQ 10 values are compared with values for other species derived from the literature. From these limited data a dichotomy emerges: species with aQ 10≏2 which apparently feed on diatoms and bacteria, the abundance of which are subject to large short term variability, and species withQ 10≏1 apparently dependent on more stable food sources.
