Study on Chlorophyll a （Chl. a） distribution and bloom patterns is essential in the upwelling areas that constitute the main fishery grounds of Vietnam. Based on high resolution satellite imagery and monthly in-situ data in period from 2007 to 2008, the spatial and temporal variations ofChl, a in the upwelling region including algal blooms have been detected. Anomalies of higher Chl. a concentration and bloom patterns occurred at different periods, locations, and bloom shapes in coastal waters of Southern Center of Vietnam. The appearances of these bloom are related to four difference reasons, such as：（i） Their locations coincided to main center of upwelling phenomena that usually occur during southwest monsoon （SWM）; （ii） Effect of northeast monsoon （NEM） that brings and attaches the nutrient into the coast and created ＂floating＂ algae bloom patches in coastal zones; （iii） The algae blooms can be potentially associated with Harmful Algae Bloom （HAB） during the SWM or local eddies during NEM and （iv） Their appearances are also as a result of distinctive nutrient inflow fi＇om Mekong delta and pumping of nutrients by internal waves in coastal shallow waters.

This paper reports some results of geo-scientific evaluation of the petroleum systems in the northeastern area of the song Hong Basin offshore Vietnam. Geological-geophysical data, including regional studies, 2D and 3D seismic ＆ logging interpretation results as well as core/cutting samples analysis were integrated to reveals that the north-eastern area were controlled by pull apart activities along song Hong river fault system, rifting phase during Eocene-Oligocene and subsidence during Miocene-Quaternary. Inversion activities at the end of Oligocene and late Miocene also play very important roles. These activities convert Pre-tertiary carbonate basement rocks to be potential reservoirs. The main source rock, overlying and adjacent to basement highs, was deposited in the lacustrine environment during rifting phase of Eocene and Oligocene and is still at the depth of oil generation window. The mentioned source rock layer is also considered as a good top seal for the basement. Petroleum system has been proven by the drilling and testing results and the studied area become more attractive and have higher chance of success.

奥西里斯、伊西丝、小荷鲁斯、塞特等的家族神话叙事,最初是对自然界现象的伦理化阐释。随着诸神黄昏时代的来临,这一神话家族叙事演化为王位继承制度的革命,即从兄终弟及制转换为父死子继制。小荷鲁斯诛杀叔父塞特为父王报仇的母题所指,也从农业神话演变为王权继承制度的更替。伊西丝对支持儿子小荷鲁斯还是兄弟塞特的伦理两难选择,体现了法老时代前夕血缘伦理的历史性偏向。

Cyanobacterial blooms associated by their toxins have been increasing in frequency in fresh water bodies throughout the world. Among the cyanobacterial toxins, microcystins (MC) are the most common and cause severe adverse impacts on plants, aquatic organisms and human beings. In this study, the effects of MC (at the concentrations of 20 and 200 μg·L-1) from field water and crude extract of cyanobacterial scum (mainly Microcystis spp.) from the Dau Tieng Reservoir, Vietnam, on the seedlings of three plants, Brassica rapa-chinensis, B. narinosa and Nasturtium officinale, were investigated for over a period of 7 days. The results showed that MC reduced the fresh weight, root and shoot length of the exposed seedlings. In addition, abnormalities of leaf shape and color of B. rapa-chinensis under exposure to MC were observed. The results implied that MC were taken up and might be accumulated in the seedlings possessing potential risk to consumers as seedlings of these plants are a common food source for Vietnamese. To the best of our knowledge, this is the first report on the effects of MC on B. rapa-chinensis, B. narinosa and N. officinale.

某一地区的应力，或该地区现今的应力场，对斜井或水平井的最佳定位，以及认识油藏特征都是非常重要的。同时地层应力也有助于我们更好地认识地球动力学过程及其对盆地演化的影响。本文在勘探和开发井的基础上，利用很多第一手分析资料对越南海岸九龙盆地和南昆山盆地沉积层的地层应力、孔隙压力等进行了分析。九龙盆地最大水平应力在北部及中央高部位主要呈NNW—SSE及N—S向；南昆山盆地最大水平应力在北部主要呈NE—SW向，而在盆地中部呈N—S向。垂向应力在3500m深处的应力梯度值约为22．2MPa／km，正常压力地层中最小水平应力值约为垂向应力值的61％。孔隙压力变化对水平应力大小的影响，可用因流体生产而引起的枯竭层中的孔隙压力及裂缝测试数据来评价，研究中得到的平均孔隙压力-应力耦合率（△Sh/△Pp）值为0．66。南昆山盆地的最小水平应力值接近于超压区的垂向应力值，这一结果表明地层具有均质性或深部超压地层中可能呈走滑断层的应力状态。

Tin dioxide(SnO_(2))has been demonstrated as one of the promising electron transport layers for high-efficiency perovskite solar cells(PSCs).However,scalable fabrication of SnO_(2) films with uniform coverage,desirable thickness and a low defect density in perovskite solar mod-ules(PSMs)is still ***,we report preparation of high-quality large-area SnO_(2) films by chemical bath depo-sition(CBD)with the addition of KMnO_(4).The strong oxidiz-ing nature of KMnO_(4) promotes the conversion from Sn(II)to Sn(VI),leading to reduced trap defects and a higher carrier mobility of SnO_(2).In addition,K ions diffuse into the per-ovskite film resulting in larger grain sizes,passivated grain boundaries,and reduced hysteresis of ***,Mn ion doping improves both the crystallinity and the phase stability of the perovskite *** a multifunctional interface engineering strategy enabled us to achieve a power conversion efficiency(PCE)of 21.70% with less hysteresis for lab-scale *** this method,we also fabricated 5×5 and 10×10 cm^(2) PSMs,which showed PCEs of 15.62% and 11.80%(active area PCEs are 17.26%and 13.72%),*** the encapsulated 5×5 cm^(2) PSM,we obtained a T80 operation lifetime(the lifespan during which the solar module PCE drops to 80%of its initial value)exceeding 1000 h in ambient condition.
