The rhizome of Angelica sinensis (Oliv.) Diels (Umbelliferae) is known as "Danggui" in China, has been used widely in traditional Chinese medicine to treat irregular menstruation, anaemia, headache, hypertension, chronic asthma and rheumatism. From the ethyl acetate extract of its roots four phthalides have been isolated. Their structures were identified by MS and NMR spectroscopic methods to be (Z)-3-butylidenphthalide, senkyunolide H, senkyunolide I and dihydroxyligustilide.
The four articles which make up this volume were originally published in successive issues of the Monthly Book Review of the Manitoba Free Press and are herewith assembled in book form in response to what appears to be a somewhat general request that they be made available in a more permanent form.

We present four techniques for online handling of Out-of-Vocabulary words in Phrasebased Statistical Machine Translation. The techniques use spelling expansion, morphological expansion, dictionary term expansion and proper name transliteration to reuse or extend a phrase table. We compare the performance of these techniques and combine them. Our results show a consistent improvement over a state-of-the-art baseline in terms of BLEU and a manual error analysis.
There are fifteen questions in part A. Forty percent are simple sentences,
others are complex sentences. All the words and phrases in the four answers are
grammatically correct when considered independently. But just only one’s is correct
about meaning. You should spend time to find out what type of structure is need to
form complete sentence. Don’t waste time to find the error in the answers.

English article for your reference to improve English proficiency. One way you can achieve this is to read a lot and look up any words you come across that you do not know. Another is to study vocabulary with
the aid of a book, preferably one that provides many opportunities for you to actually practice using the words (like this one).
Hi everyone. Welcome to the point of view stories for "Assisted Living". I hope that you're in a great mood and that you're excited to get started. Today we’re going to hear the same story from the "Assisted Living" mini-story told in four different points of view. So we’ll hear four different versions of this story. Okay, here we go.
Jackie has her hands full. She works as a lawyer for twelve hours every day. She needs a vacation because she's really stressed out. Jackie’s cousin Mary lives in Thailand. She tells Jackie to visit her in Thailand....
A preliminary study was carried out in mid 1999 on the status and potential impact of the introduction
of exotic fish species in the Mekong Basin. Introductions have been made for four main purposes:
aquaculture, stocking into lakes and reservoirs, pest control (mosquito) and the aquarium fish trade.
Introductions of exotic species and movements of large quantities of fish for stocking are accompanied
by risks to the environment, the possibility of native fish species declining through competition, predation
or genetic interference, and the possible spread of disease....
Design patterns provide good solutions for problems occurred in the design stage. Using design patterns in the software development processes helps improve productivity and quality of software products. Pattern Oriented Analysis and Design Process has four steps related to patterns, namely the acquaintance with design patterns in the pattern library, the retrieval of the pattern candidate, the selection of suitable patterns and the application of selected patterns.

Part A of this report will include two sections, which understand who I as a
learner am; and implication for my future career choice.
Firstly, definitions of ‘learning’ will be mentioned through understanding of
learner. Besides, this going to find out on my own personal analyses about learning
styles through four psychological tests, which are VARK, the Myers Briggs Type
Indicators (MBTI), the Honey and Mumford Learning styles Questionnaire, and the

The switching regulator is increasing in popularity because it offers the advantages of higher power conversion efficiency and increased design flexibility (multiple output voltages of different polarities can be generated from a single input voltage). This paper will detail the operating principles of the four most commonly used switching converter types: Buck: used the reduce a DC voltage to a lower DC voltage. Boost: provides an output voltage that is higher than the input. Buck-Boost (invert): an output voltage is generated opposite in polarity to the input....
We describe a simple variant of the interpolated Markov model with non-emitting state transitions and prove that it is strictly more powerful than any Markov model. Empirical results demonstrate that the non-emitting model outperforms the interpolated model on the Brown corpus and on the Wall Street Journal under a wide range of experimental conditions. The nonemitting model is also much less prone to overtraining. The remainder of our article consists of four sections.
The water soluble crude polysaccharide obtained from cultured mycelia of Cordyceps militaris (CPM)
by hot water extraction followed by ethanol precipitation was fractionated by DEAE cellulose and
Sepharose CL-6B column chromatography. This fractionation process resulted in four polysaccharide
fractions that were termed CPMN Fr I, CPMN Fr II, CPMN Fr III, and CPMN Fr IV. Of these fractions,
CPMN Fr III was able to upregulate the functional events mediated by activated macrophages, such
as production of nitric oxide (NO) and expression of cytokines (IL-1b and TNF-a).
Digital Elevation Model (DEM) is an important component of GIS applications in many socio-economic areas. Especially, DEM has a very important role in monitoring and managing natural resources, preventing natural hazards, and supporting spatial decision making. Usually, DEM is built by interpolation from a limited set of sample points. Thus, the accuracy of the DEM is depended on the used interpolation method.
This study briefly summarizes the thunderstorm activities in Vietnam. To predict thunderstorms in the Noi Bai Airport region, the thunderstorm indices are calculated for 64 grid points nearby Noi Bai region from the predicted meteorological fields with RAMS (Regional Atmospheric Modeling System) model. The forecast procedure for thunderstorm is built for this region with four prediction factors, such as CAPEmax, Kimax, SI min, Vtmax in the forecast threshold of 0.6. As a result, the occurrence of thunderstorms reaches 80% for the duration of 36 hours.
This paper analyzes four important issues related to national renewable energy policies including strategies for energy development, policies on financial supports for renewable energy development, use of taxes and fees for energy management, policies on energy consumption.
