Sugarcane burning during harvest and non-harvest season emits various pollutants like volatile organic compounds (VOCs), alkanes, and PAHs (Polyaromatic hydrocarbons) in the surrounding environment. Among these pollutants, PAHs are of uttermost concern due to their high level of toxicity. Burning of sugarcane bagase in sugar mill results in the production of fly ash. Fly ash is produced as a result of sugarcane bagasse burning in sugar mills. In present study, fly ash that comes out from the sugar mill chimney was collected from Western Uttar Pradesh, India and used for further analysis. High temperature and incomplete combustion inside chimney lead to the formation of PAHs. Extraction of PAHs present in fly ash samples was done by ultrasonication method and was identified with GC-FID (gas chromatography-flame ionization detector). results exhibit the presence of eight PAHs in fly ash samples where the Benzo(a)pyrene and Naphthalene were found to be in high concentration. Furthermore, we have evaluated toxic effects of fly ash and Polyaromatic hydrocarbons (Standard of BaP & Nap) through different methods i.e. MTT, rOS and comet assay. Significant reduction (p reated with fly ash as compared to control. Fly ash samples were also found to induce significant oxidative stress in HeLa cells, which ultimately causes DNA damage. Therefore, it may be concluded that the fly ash samples are toxic to the environment due to the presence of PAHs. Hence, the present study plays an important role in determining the harmful effects of PAHs and their source of occurrence.

A field experiment was conducted at TamilNadu agricultural university, Coimbatore during rabi 2011 to study the effect of time transplanting on growth, yield attributes and resultant seed quality of davana. The experiment was laid out with five different dates of transplanting viz., October 15th, November 1st, November 15th, December 1st and December 15th with the spacing of 15 × 7.5 cm and 125:125:75 NPK kg/ha were adopted in a randomized block design with four replications. The results revealed that the seedlings transplanted at 15th November recorded the maximum number of branches/plant, seed yield/plant, seed yield/plot, resultant seed germination and vigour index.

引言儒艮（Dugongidae：Dugong dugon）如果尚未绝迹。其残留种群在一些濒临灭绝的区域有片断性分布。但是，1999年报道马来西亚半岛柔佛州（Johors）附近海域发现一批儒艮死亡的事件之后，儒艮被认为在马来西亚海域仍有存在。该事件使儒艮在马来西亚的生存现状受到关注。重新激起了相关学者对儒艮进行研究的兴趣。在马来西亚东部，儒艮以小片断种群分布于沙巴州的山打根（Sandakan District）、直落文莱（Tcluk Brunei）和古达（Kudat District）沿岸海草丛生的水域。

Objective:To investigate the antimalarial and larvicidal activities of seaweeds against Plasmodium falciparum strain andAnopheles stephensi mosquito larva. Methods: The three different seaweeds,Jania rubens,Turbinaria ornata (T. ornata) and Ulva fasciata were collected from Southeast India. The seaweeds were extracted using hexane and ethyl acetate solvents and evaluated for their mosquito-larvicidal and antiplasmodial property. The bioactive compounds of the seaweed extract were studied by Fourier transform infrared spectroscopy and gas chromatography-mass spectrometry. results:The hexane extract ofT. ornata (HTO) has shown significant inhibitory effects at the IC50 value 22.98 μg/mL, when compared to the positive control, chloroquine (12.32 μg/mL). The larvicidal activity of HTO on the fourth instar larvae of Anopheles stephensi was found to be effective with the LC50 and LC90 values (μg/mL) of 1.38 and 3.34. The Fourier transform infrared spectroscopy analysis ofHTO revealed the presence of alkenes, aromatics, amides and amines groups, whereas in gas chromatography-mass spectrometry, 11 different bioactive components were recorded. The bioactive component, hentriacontane in the HTO might be responsible for the recorded antiplasmodial and larvicidal activities. Conclusions:The finding of the present study reveals that the constituents of T. ornata have new sources of antimalarial and larvicidal agents in future.

利用广泛的发动机试验和运行循环仿真,确定了在非道路瞬态循环和特定用途中降低运行成本的潜力。采用1台6缸柴油机作为试验发动机,配装电装公司第4代G4S共轨喷油系统,能够达到300 MPa的喷射压力,并采用FEV公司的先进重型燃烧系统。基本型发动机在装备喷射压力达200 MPa左右的现代喷油系统时,在不带后处理装置的前提下可满足美国第4阶段中期排放标准。电装公司的G4S喷油系统除了能达到300 MPa的喷射压力外,还具有静态防漏喷油功能,因此对于给定的喷油量,可最大限度地减少建立压力所需的泵油能量。
