Genetic Analysis of the P1 Region of Human Enterovirus 71 Strains and Expression of the 55 F StrainVP1 Protein

Enterovirus 71 （EV71） is a member of the Entero-virus genus of the Picomaviridae family and is the major cause of Hand, foot, and mouth disease （HFMD） in children. Different strains from Gansu were cloned and the P1 protein was sequenced and analysed. Results indicate that there are three kinds of EV71 infections prevalent in Gansu. The VP 1 protein from one of these strains, 55F, was expressed. The recombinant protein was expressed with high level and reacted specifically with the EV71 patient antibody, the recombinant protein was also applied to raise antiserum in rabbits and after the fourth injection a high titer of antiserum was detected by ELISA assay. These data are useful for further clarification of prevalent EV71 strains in the north of China at the molecular level and provide a basis for EV71 diagnosis.

Radon in Rented Accommodation and Variables Determining Its Level

Indoor radon levels were measured in 221 homes in rented accommodation. In addition, buildings were registered for a series of variables describing building characteristics and used materials. The mean year value of the indoor radon level was 30.7 （1~250） Bq/m3. The indoor radon level exceeded 100 Bq/m3 in 5.9% of the homes. Of the investigated variables, only homes in single-family terraced houses, were statistically significant. Approx： 75% of homes exceeding 100 Bq/m3 indoor radon level had levels between 100 and 200 Bq/m3 and 25% had indoor radon levels exceeding 200 Bq/m3. Significant differences in indoor radon levels were found in homes located in multi-occupant houses. Additionally, the risk of indoor radon levels exceeding 100 Bq/m3 in homes in multi-occupant houses was found to be very low, but the risk was the highest on the ground floor in a building constructed with slab on ground.

Application Research of the Integrative Mathematics Model in Household Consumption Behavior

In this paper, two hypotheses are integrated into an independent model to explain consumer behavior. The model is empirically tested using data from China Family Cost Survey of 2001. The results indicate that China household consumption behavior is commonly explained by two hypotheses as an independent model, reverse to previously treating them as commutative exclusive hypotheses.

Study on regulation of potassium loss and its balance characteristics from typical paddy soils in Dongting Lake area

Potassium loss due to runoff and leaching, crop uptake, and K-fertilizer input, irrigation and wet deposition was studied, subsequently potassium balance characteristics was analyzed using lysimeter modeled two typical paddy soils from double rice field in Dongting Lake area. K losses due to runoff and leaching in Alluvial Sandy Loamy Paddy Soil （ASL） with lower cation exchange content （CEC） and clayey granule content were increased significantly compared with those in Reddish Yellow Loamy Paddy Soil （RYL） with higher CEC and clayey granule content. Compared with RYL, lower economic and biological yield due to lower capacity of nutrient and water keeping in ASL resulted in lower K uptake. So potassium deficit in double rice field of RYL was more serious than that of ASL because main K proportion was accounted by crop uptake. Available K in soil of surface layer （0-15 cm） was decreased significantly due to long term nutrient management of K deficit in double rice field. The straw return paddy field was suggested as an effective way to increase soil K and balance K deficit in double rice field because large amount of potassium was enriched in rice straw at harvest.

The Research for Sustainble Poverty Reduction in Khmer Ethnic Community

The research for sustainable poverty reduction for Khmer ethnic people in Tra Vinh province was conducted by the use of statistic approach, the current situation of poor households of Khmer ethnic people in Tra Vinh province, the interview with 300 Khmer households living in seven districts and cities of Tra Vinh province. Research findings show that there are a number of factors affecting the income of Khmer households, including the career of householders, the level of education, the ratio of dependants, living experience of the householders, the land square area, people＇s participation in different festivals; the number of household members, the number of activities for income and the gender of the householders. Of all the factors, occupation, level of education, and the ratio of dependants are considered to have the biggest influence on the income of Khmer ethnic people in Tra Vinh province.

The Effect of Family Planning Methods on Food Security in Oyo State, Nigeria

This study affirms the effect of family planning on rural household food security. The major thrust of this research identified socio-economic characteristics of respondents, various family planning methods used, benefit of use and factors influencing household food security in the study area. The research was carried out in 4 Local Government areas （LGAs） of Oyo state, where five communities each were randomly selected from the LGAs. A total of 272 households were sampled from the 20 communities. Descriptive and multinomial logit regression were used to analyse data collected. Findings revealed that 64.4% of the respondents were female, mean age was 40 years; about 80% of them were married and most of them had formal education with average of 10years spent in school. Result further revealed that that most of the respondents adopt artificial method of family planning. Sex, marital status of respondent, number of children; primary occupation, traditional method, natural method and artificial method of family planning were the factors influencing household food security status. It was recommended that rural household should be enlightened on the advantages of the use of family planning to improve their household nutritional intake level as well as standard of living.

Singular Values and Real Fixed Points of One Parameter Family of Function zbz/（bz-1）

The purpose of this paper is to study the singular values and real fixed points of one parameter family of function,fλ（z）=λab2/b2-1,fλ（0）=λ/lnb for λ∈R／{0},z∈C and b〉 0 except b = 1. It is found that the function fλ（z） has infinitely many singular values for all b 〉 0 except b = 1. It is also shown that, for 0 〈 b 〈 1, all the critical values of fλ（z） lie in the left half plane while, for b 〉 1, lie in the right half plane. Further, it is seen that all these critical values are outside the open disk centered at origin and having radius ｜λ/lnb｜for all b 〉 0 except b = 1. Moreover, the real fixed points of fλ （z） and their nature are investigated.

Comparative Analysis of Household Consumption Pattern of Local and Imported Rice in Ekiti State, Nigeria

The paper examined the consumption pattern and attitude of households for local and imported rice in Ekiti State, Nigeria. The specific objectives of the paper are to： examine the household preference and consumption level of local and imported rice, examine price variation between local and imported rice and identify the major problems confronting marketers of local and imported rice. Data were collected from 100 randomly chosen households with the aid of structured questionnaire. Data collected were analyzed with the use of descriptive statistics such as frequency, percentages, chi-square, t-test and regression analysis. The paper revealed among others that majority of the respondents prefer to consume local rice to imported rice because of its more palatability, health benefits, readily availability and relatively cheap price. The average price per kilogramme of local rice is 200 Naira compared to that of imported rice which is 300 Naira. The difference in price is as a result of exchange rate and costs associated with smuggling of imported rice across the border of Nigeria from neighbouring countries. Nonetheless, the quality of local rice is still very low when compared to imported rice in terms of degree of impurities such as stone and shafts and the level of polishing.

Normal family and the sequence of omitted functions

Let {fn} be a sequence of meromorphic functions on a plane domain D, whose zeros and poles have multiplicity at least 3. Let {hn} be a sequence of meromorphic functions on D, whose poles are multiple, such that {hn} converges locally uniformly in the spherical metric to a function h which is meromorphic and zero-free on D.If fn≠hn, then {fn} is normal on D.

More than six hundred new families of Newtonian periodic planar collisionless three-body orbits

The famous three-body problem can be traced back to Isaac Newton in the 1680 s. In the 300 years since this "three-body problem"was first recognized, only three families of periodic solutions had been found, until 2013 when ˇSuvakov and Dmitraˇsinovi′c [Phys.Rev. Lett. 110, 114301(2013)] made a breakthrough to numerically find 13 new distinct periodic orbits, which belong to 11 new families of Newtonian planar three-body problem with equal mass and zero angular momentum. In this paper, we numerically obtain 695 families of Newtonian periodic planar collisionless orbits of three-body system with equal mass and zero angular momentum in case of initial conditions with isosceles collinear configuration, including the well-known figure-eight family found by Moore in 1993, the 11 families found by ˇSuvakov and Dmitraˇsinovi′c in 2013, and more than 600 new families that have never been reported, to the best of our knowledge. With the definition of the average period T = T=Lf, where Lf is the length of the so-called "free group element", these 695 families suggest that there should exist the quasi Kepler's third law T* ≈ 2:433 ± 0:075 for the considered case, where T*= T|E|^(3/2) is the scale-invariant average period and E is its total kinetic and potential energy,respectively. The movies of these 695 periodic orbits in the real space and the corresponding close curves on the "shape sphere"can be found via the website: http://numericaltank.sjtu.edu.cn/three-body/three-body.htm.

Section extension from hyperbolic geometry of punctured disk and holomorphic family of flat bundles

The construction of sections of bundles with prescribed jet values plays a fundamental role in problems of algebraic and complex geometry.When the jet values are prescribed on a positive dimensional subvariety,it is handled by theorems of Ohsawa-Takegoshi type which give extension of line bundle valued square-integrable top-degree holomorphic forms from the fiber at the origin of a family of complex manifolds over the open unit 1-disk when the curvature of the metric of line bundle is semipositive.We prove here an extension result when the curvature of the line bundle is only semipositive on each fiber with negativity on the total space assumed bounded from below and the connection of the metric locally bounded,if a square-integrable extension is known to be possible over a double point at the origin.It is a Hensel-lemma-type result analogous to Artin's application of the generalized implicit function theorem to the theory of obstruction in deformation theory.The motivation is the need in the abundance conjecture to construct pluricanonical sections from flatly twisted pluricanonical sections.We also give here a new approach to the original theorem of Ohsawa-Takegoshi by using the hyperbolic geometry of the punctured open unit 1-disk to reduce the original theorem of OhsawaTakegoshi to a simple application of the standard method of constructing holomorphic functions by solving the equation with cut-off functions and additional blowup weight functions.

Social class differences in parent educational expectations:The relationship between parents’social status and their expectations for children’s education

To achieve the overall goals and purposes of education is closely related to the living environments of students.Different family backgrounds will put children into a situation where they face unfair competition.According to a survey conducted in China’s Urumqi and Changchun about parents’awareness of educating their children,this paper will suggest that families with different backgrounds have different expectations for their children’s education.Moreover,it suggests that parents’social status is related to their children’s education expectations.Therefore,we can find that parents’social status influences their children’s education,and their positions in social class are related to education.
