In traditional views, oilfield is abandoned after water flooding and chemical flooding. But the recovery is only 50%-60%, that is to say, more than 40% of the resource is still left underground. Therefore, how to utilize this part of resource economically and effectively is a key problem to be tackled. Based on the lab experiments and theoretical researches on viscosity-temperature relationship, displacement and relative permeability under high temperature, the mechanism of enhancing oil recovery through steam flooding in super-high water cut stage of water injection oilfield was analyzed. The experimental results showed that steam flooding in 200 C after polymer flooding could increase oil displacement efficiency by 14.5%. Water flooding and polymer flooding had been implemented in Sabei development area of Daqing Oilfield since it was brought into development in 1963. The recovery had reached above 70% and the water cut had exceeded 98%. There was no economic benefit to develop continually, the oilfield faced abandonment. Steam flooding test was carried out to enhance oil recovery on this basis. According to the geological characteristics and development status, special technical measures were taken based on the lab experiments and numerical simulation including high-pressure steam injection to improve heat utilization, forced fluid withdrawal to increase production rate, insulated tubing and nitrogen insulation to keep the bottom hole steam dry, and tracking analysis to adjust injection-production parameters duly. The ultimate recovery reached 81.6% which increased 10.7% on the original basis, the field test was successful technically. Steam flooding is characterized with quick effect, high production rate and high producing degree of residual oil. This successful technology provides a direction for secondary development after polymer flooding in water flooding oilfield.

Mango is a type of tropical fruit which popular among the consumers and have high commercial value. Moreover, this fruit also good for human health as contain lots of vitamins, mineral, and fiber. The largest production area of mangoes in Indonesia is East Java Province, followed by Central Java, West Java and West Nusa Tenggara. In West Nusa Tenggara Province, mangoes mostly cultivated in yards and in mixed gardens with conventional technological approaches. However, low quality of mangoes from West Nusa Tenggara Province was indicated due to lack of Good Agricultural Practices (GAP). The one being developed is Cultivar Gedong Gincu which is native to Indonesia and acceptable for both local and export purposes. This study aims to observe the effects of pruning and fertilizing on the production of mangoes as well as its post harvest quality. The experiment was conducted at farmer's farm in the village of Mumbulsari, Sub District of Kayangan, North Lombok, West Nusa Tenggara Province of Indonesia, from January 2010 until January 2011. It consisted of seven treatments. Each treatment was repeated five times;therefore the experiment was using 35 test trees. Test trees were mangoes cultivar Gedong Gincu, average 12 years old trees and have uniform appearances. The parameters observed were varied but more focus on total number of fruits, total production, and malformation. Mango production management through a combination of 500 gram ZA fertilizer/tree + 1500 gram of SP36/tree + 1000 gram of KCl/tree + 80 gram B/tree + pruning could increase total number of fruits by 240.60% and increase total production by 269.80% compared to control treatment. In addition, use of Boron could significantly reduce the fruit sitting (malformation) from 7.22% (control) to 3.12 %.

The first successful EPWS(Equitable Payment for Watershed Service) case is in Peru where there had finished whole three phases with excellent operation under the internal motive force between upstream community and downstream water supply company from 2009 to date. In China, the first EPWS programme in 2011 had followed the successful EPWS cases to find the adaptability of EPWS development in other watershed in Chian. Rapid hydrology appraisal for EPWS is most basis technology need. In this study, the sedimentation has been assessed and forecasted by GIS technology by using the measured sediment data. The average contribution of SS loads from Yuping Village and Ganzikou Village were about 67% of EPWS area. This rapid hydrology appraisal had paid a key role to cause the signature of MOU on June 1th 2012 between upstream communities and downstream hydropower station. The next phase of EPWS will be carried out the planned livelihood strategies within water and soil erosion protection by upstream communities, then produced watershed service (reduced sediments) will be monitored and assessed by downstream hydropower station or other organizations. © (2013) Trans Tech Publications, Switzerland.

This paper concerns the problem of standing tree volume measurement based on digital image processing. A computer and a camera were used in our work. Before the tree photo was taken, two red color marking labels were attached on the trunk. After the marking points and the tree trunk were extracted, the tree trunk edges were fitted with a high order curve. Then the volume of tree trunk of any height selected with a rectangle can be calculated. The experimental results show that the relative measurement error is low enough. So it is a viable method.

This paper presents the results of an experimental study on the compressive strength, splitting tensile strength and modulus of elasticity characteristics of high performance concrete. These tests were carried out to evaluate the mechanical properties of HPC for up to 7 and 28 days. Mixtures were prepared with water to binder ratio of 0.40. Two mixtures were containing fly ash at 25%, silica fume at 5% cement replacement, respectively. Another mixture was contains blast furnace slag and fly ash at 25%. Three standard 100 x 200 cylinder specimens were prepared. HPC showed improvement in the compressive strength and splitting tensile strength when ordinary Portland cement was replaced with silica fume. Compare with specimens FA25 and BS25FA25, specimen SF5 showed much more modulus of elasticity. It shows that the use of the blast furnace slag of 25% and fly ash of 25% cement replacement has caused a small increase in compressive strength and splitting tensile strength and modulus of elasticity compared to the only use of fly ash of 25% at 28days. The results indicated that the use of blast furnace slag or silica fume provided the good performance compare to fly ash when the mechanical properties of the high performance concretes were taken into account.

In order to fabricate a kind of amphiphilic hot-melt pressure sensitive adhesives (HMPSAs) suitable for transdermal drug delivery systems (TDDS) of natural medicines, SIS-based hot-melt pressure sensitive adhesives were modified by a melt-blending method, in which a kind of hydrophilic poly (ethyl acrylate-co-methyl methacrylate-co-trimethylammonioethyl methacrylate chloride) (RLPO) and polyethylene glycol 2000 (PEG2000) were utilized. Functional RLPO and its plasticizer PEG2000 worked as a hydrophilic skeleton of amphiphilic HMPSAs. SEM and FT-IR results indicated that RLPO and SIS were partially compatible with each other through n-pi complex between the n electrons of the carbonyl group of RLPO and the it electrons of the benzene rings of SIS and their compound had a good thermal stability. The phase microscope images showed that PEG could improve the compatibility between RLPO phase and SIS phase. As the ratio of SIS/RLPO/PEG equaled to 1/2/1.6, their compounds obtained bi-continuous structures. Geniposide (logP<0) and oleanic acid (logP=9.0) were chosen as representatives of hydrophilic drugs and lipophilic drugs, respectively. It was observed that both hydrophilic drugs and lipophilic drugs had a continuous release in the optimized amphiphilic HMPSAs. In addition, the release behavior of hydrophilic geniposide could be controlled by adjusting the ratio of RLPO to PEG.
