Effect of Acorn Burying Depth on Germination, Seedling Emergence and Development of Quercus aliena var. acuteserrata

Acorns of Quercus aliena var. acuteserrata Maxim. are often predated by small mammals and birds in natural forests. These animals not only eat the acorns during the acorn ripening season, but also cache and hoard most of the remaining acorns on the forest floor in the soil for their future use. These buried acorns form the main seed resource for regeneration. Burying depth is potentially important for germination and for seedling development. The effects of burying depth on germination and seedling development in relation to acorn size were studied in an experiment, in which acorns were planted at 6 cm-, 12 cm- and 18 cm-depth. The experimental results showed that fewer acorns germinated as burying depth increased. From the deeply buried acorns fewer seedlings emerged at later time than from those acorns buried less deeply. They appeared to have more difficulties to emerge above-ground than die seedlings from shallowly buried acorns. The deeply buried acorns and their seedlings also appeared to be more susceptible to rot. Acorn size did not significantly affect germination and emergence of the seedlings. As early emerged seedlings had longer developmental periods in their first growing season, and therefore grew better than die late emerged seedlings, seedlings from die shallowly buried acorns took the advantage.

The Progress on Abnormal Development Mechanism

What summarized in this paper is the progress in recent years' in the causdive mechanism on study of developmental toxicants as chemical teratogenesis in three aspects.(1) It is about the phenomena and the possible reason of chemical teratogenesis in the preimplantation period. These research results are contrary to the past traditional concepts. (2) Due to using much more molecular biology methods, it can be observed more dead foetus phenomena before birth, which cannot be done previously and are of great value for reference. (3) When analyzing the genetic reason of chemical abnormal, a new research idea may be showed, i.e. the developmental abnormal due to chemical teratogenesis is induced with association of more relative genes and their expression abnormal. 13 references are involved in.

Research on Embryonic Development of Loach

[Objective] Aim to know the whole process of embryonic development of loach. [Method] DOM + LHRH-A2 was used to induce spawning of loach,then after fertilization,the embryos were cultured into freshwater water with temperature from 24 to 26 ℃ and pH from 7.0 to 7.5. The embryonic development of loach was observed and 27 concrete morphological characteristics and development time of loach from fertilized egg to newly hatched larval period were described in detail. [Result] The embryonic development of loach could be divided into cleavage stage,blastocyst stage,gastrula stage,neurula stage and organogenesis stage. The loach embryo from fertilized egg to out membrane period was 30 h 45 min in fresh water from 24 to 26 ℃ and pH from 7.0 to 7.5. [Conclusion] It provided important reference for studying artificial propagation and genetic breeding of loach.

Study on Seed Breeding of Thuia sutchuenensis

Objective] This research almed to study technical requirements by seed breeding of Thuia sutchuenensis so as to Iay a foundation for the saving and breeding of Thuia sutchuenensis. [Method] The seeds of Thuia sutchuenensis, coI-Iected from Xianyi Town, Chengkou County, Chongqing City, were used as material. The effects of temperature and matrix on germination rate and emergence rate of Thuia sutchuenensis were investigated. In addition, the controI effects of different-type and different-concentration pesticides on seedIing bIight of Thuia sutchuenensis were also studied. [Result] The suitabIe temperature for seed germination of Thuia sutchuenensis was 15-20 ℃, whiIe the optimum temperature was 20 ℃, under which the germination rate couId reach 95%. At temperature of 25 ℃, the seeds of Thuia sutchuenensis almost couId not germinate. The seeds of Thuia sutchuenensis germinated most if soaked in warm water of 40 ℃. After 24 h soaking, the germi-nated seeds were not increased significantIy. Among the matrixes for contalner seedIing, the 18th matrix, composed by sawdust （2/3） and forest topsoiI or general soiI （1/3）, was conducive to the seed germination in contalners. Among the pesti-cides, the controI effect of ferrous suIfate on diseases and pests in Thuia sutchue-nensis was best with cumuIative incidence of 15%, foI owed by those of fe-naminosuIf （17%）, Bordeaux mixture （21%）, KangkuIing （22%） and potassium per-manganate. [Conclusion] Sawdust had great effect on emergence rate of Thuia sutchuenensis in contalner seedIing, which might be reIated to good water retention and permeabiIity of sawdust. However, too much forest soiI was not conducive to the emergence rate of Thuia sutchuenensis in contalner seedIing. Ferrous suIfate had the best controI effect on diseases and pests in Thuia sutchuenensis.

Inflammatory bowel disease in pregnancy

Crohn's disease and ulcerative colitis affect women in their child-bearing years. Family planning has come to be a common discussion between the gastroenterologist and the inflammatory bowel disease (IBD) patient. Disease control prior to desired conception and throughout pregnancy is the most important thing to keep in mind when caring for the IBD patient. Continued medical management during pregnancy is crucial in optimizing outcomes. Studies indicate that quiescent disease prior to conception infer the best pregnancy outcomes, similar to those in the general population. Active disease prior to and during pregnancy, can lead to complications such as pre-term labor, low birth weight, and small for gestational age infants. Although there are no definitive long term effects of pregnancy on IBD, there are some limited studies that suggest that it may alter the disease course. Understanding the literature and its limitations is important in the modern era of IBD care. Educating the patient and taking a team approach with the obstetrician will help achieve successful outcomes for mother and baby.

Gastric angiodysplasia in a hereditary hemorrhagic telangiectasia type 2 patient

Hereditary hemorrhagic telangiectasia(HHT)is a rare autosomal-dominantly inherited disease that occurs in approximately one in 5000 to 8000 people.Clinical diagnosis of HHT is made when a person presents three of the following four criteria:family history,recurrent nosebleeds,mucocutaneous telangiectasis,and arteriovenous malformations(AVM)in the brain,lung,liver and gastrointestinal(GI)tract.Although epistaxis is themost common presenting symptom,AVMs affecting the lungs,brain and GI tract provoke a more serious outcome.Heterozygous mutations in endoglin,activin receptor-like kinase 1(ACVRL1;ALK1),and SMAD4,the genes involved in the transforming growth factor-βfamily signaling cascade,cause HHT.We report here the case of a 63 year-old male patient who presented melena and GI bleeding episodes,proven to be caused by bleeding from multiple gastric angiodysplasia.Esophagogastroduodenoscopy revealed multiple angiodysplasia throughout the stomach.Endoscopic argon plasma coagulation was performed to control bleeding from a gastric angiodysplasia.The patient has been admitted several times with episodes of hemoptysis and hematochezia.One year ago,the patient was hospitalized due to right-sided weakness,which was caused by left basal ganglia hemorrhage as the part of HHT presentation.In family history,the patient's mother and elder sister had died,due to intracranial hemorrhage,and his eldest son has been suffered from recurrent epistaxis for 20 years.A genetic study revealed a mutation in exon 3 of ALK1(c.199C>T;p.Arg67Trp)in the proband and his eldest son presenting epistaxis.

Analyzing the Relationships Between Factors Affecting Adolescents＇ Happiness in OECD Countries

The aim of this study is to investigate the causal relationships between key factors relating to education that affect the happiness of adolescents, and to put forward policy suggestions wherewith 20 OECD countries may raise their levels of adolescent happiness. The HBSC score of adolescents from 20 OECD countries was selected as an indicator for happiness, and a number of independent variables such as per capita GDP and per capita educational expenditure were included in the analysis. A structural equation model was employed for the analysis. The research results show that the variables that directly affected happiness were per capita educational expenditure, educational decentralization level, number of students per teacher, and others. Of these, per capita educational expenditure had the greatest influence. Of the paths to adolescent happiness, those that contained a significant indirect effect were ＂per capita GDP → per capita educational expenditure → happiness＂ and ＂educational decentralization → number of students per teacher → happiness＂, which were significant at the level ofp 〈 0.05. Compiling the paths toward adolescent happiness focusing on the significance of these direct and indirect effects shows that the ＂per capita GDP →per capita educational expenditure → happiness＂ path has the greatest effect.

Primary Educational Productivity ： A Study Based on Stochastic Frontier Educational Production Function Model

This paper builds a stochastic frontier educational production function model, estimating the primary educational productivity with annual data of 31 provinces from 2007 to 2011. The conclusions are as follows： （1） in educational production function, output elasticity of public educational expenditure exceeds private educational expenditure＇s. The degrees of contribution of public and private educational expenditure reflect that China should increase public educational expenditure. （2） regional educational technical efficiency is affected by both structure of educational expenditure and levels of regional economic growth. Primary educational technical efficiency of east, middle and west regions all tended to fall down during 2007 to 2011.

A Model to Analyze Small and Medium Enterprises＇ Training Needs Related to the Internationalization

Formal training can play a particularly important role in supporting the internationalization of small and medium enterprises （SMEs）. However, the demand for education services by the latter still appears limited. This is due to known structural and cultural limits that are found widely in this type of business and to the fact that the provision of training---especially that which is funded^oes not seem to address adequately SMEs＇ needs; in many cases, such training is not stimulating, because it is perceived as too general. In fact, SMEs do not constitute a single homogeneous group and therefore assistance needs vary among the different types of firms. So, especially in relation to internationalization, it is clear that there are important differences to consider due to the variety of approaches and ways of developing this process. In order to optimize the resources to invest in the promotion of training, there is a need to find a proper balance between providing ＂viable solutions for all businesses＂ and offering ＂targeted responses and tailored services＂. In such a context, the main objective of this paper is to identify and systematize the variables that most influence the SMEs＇ training needs related to internationalization by taking into account the differences among them. To this end, an empirical analysis was developed involving a significant number of Italian SMEs by using a combination of qualitative research methods. The results show the critical issues faced by the investigated firms during their internationalization process and highlight some important variables that affect their training needs： export involvement, characteristics of the product/market, characteristics of the company, exporting strategy, and human resources. Based on these variables, the writers identified clusters of firms characterized by similar needs and problems to be faced.

Hemobilia due to hepatic artery aneurysm as the presenting sign of fibro-muscular dysplasia

Fibro-muscular dysplasia(FMD)is a rare but well documented disease with multiple arterial aneurysms. The patients,usually women,present with various clinical manifestations according to the specific arteries that are affected.Typical findings are aneurysmatic dilatations of medium-sized arteries.The renal and the internal carotid arteries are most frequently affected, but other anatomical sites might be affected too.The typical angiographic picture is that of a"string of beads". Common histological features are additionally described. Here we present a case of a 47-year-old woman,who was hospitalized due to intractable abdominal pain.A routine work-up revealed a liver mass near the portal vein.Before a definite diagnosis was reached,the patient developed massive upper gastrointestinal bleeding.In order to control the hemorrhage,celiac angiography was performed revealing features of FMD in several arteries, including large aneurysms of the hepatic artery.Active bleeding from one of these aneurysms into the biliary tree indicated selective embolization of the hepatic artery.The immediate results were satisfactory,and the 5 years follow-up revealed absence of any clinical symptoms.

Analysis on Chinese Talent Loss Status from the Higher Education Perspective

In recent years, selection range of Chinese students for institutions of higher education is no longer limited to domestic range, with the rise of studying abroad, an increasing number of undergraduate and graduate students choose to go to the overseas for expansion of knowledge.This phenomenon has both advantages and disadvantages,on the one hand, it can promote the cultural exchange between countries,but on the other hand, the higher talent loss on China＇s economy caused great damage.For China＇s higher education workers and researchers, our research scope is not limited to the cultivation of the higher talents, and it also considers how to cultivate talent substantial contribution to economic civilization construction of the motherland without loss to foreign countries.This paper aims to analyze the current situation of higher talent loss in China from the perspective of higher education, and carries on the brief analysis on how to deal with this situation.

The Theory and Practice of Research-and-Discussion Teaching --Taking the Animation Teaching as an Example

Along with the support policy for the development of domestic animation by State Administration of Press, Publication, Radio, Film and Television of The People＇s Republic of China and local governments, the domestic animation industry has wide development prospects. According to statistics, there are more than 500 colleges and universities opening animation specialty and more than thousands of universities having related courses. But in recent years, there has been a contradictory phenomenon. On one hand, it is really hard for large numbers of graduates to find jobs related to animation. On the other hand, it is difficult for domestic animation enterprises to recruit outstanding animation talents. The main reason for this phenomenon is that the animation education in colleges and universities can not satisfy the demand from market and can not meet the requirements of the animation industry development in china.So we have the necessity to discuss the suitable education mode for animation development.

Globalization and Education for All： The Challenge of the Twenty-First Century

Recently more and more people talk about ＂globalization＂ with loads of semasiological variety： mainly economic but also cultural. Many perceive it as a significant progress, others as an undisputed threat. However, despite the euphoria that faces this phenomenon, globalization is an evolving process. The fact remains that this is a progressive development of economic, scientific, political, and cultural aspects of all peoples of planet Earth turning it into a big city with many differences, in particular in education and educational activities. This paper will try to illuminate fundamental issues as： （1} understanding the notion of globalization in relation to both pedagogical principles in the field： the integrity and completeness; （2） elements of globalization, as a necessary process and development factor; and （3） ＂education for all＂ challenges for the twenty-first century. The content of global education in the scientific publication is given analytical processing, linking globalization in education with the development of democracy and human rights, global ethics, the influence of European norms, standards and the global world, the impact of European and world norms and standards, as well as the penetration of global civic cultural elements.

A Case Study of China as an Exporter of Higher Education Using Push-Pull Theory

Developing countries establishing international branch campuses （IBCs） is an emerging trend, and currently compromises 17% percent of the market in terms of the number of IBCs. While researchers have applied different social science perspectives to analyze cross-border higher education and IBCs, they usually emphasize developed countries as exporters and developing countries as importers of higher education. The phenomenon of developing countries as exporters of higher education has seldom been looked at so far in the research. This paper first describes the current development of IBCs, then illustrates what social science perspectives have been used on this topic, followed by how push-pull theory relates to developing countries being exporters of IBCs. The paper aims to combine E.S. Lee＇s push-pull theory and Gu＇s push-pull framework to analyze the push and pull factors in their advertisement and marketing claims when higher education institutions （HEIs） from developing countries plan to establish branch campuses in foreign countries. Soochow University in Laos is used as a case study. Furthermore, intermediate barriers and solutions are also identified in this case study. However, this case study has its own uniqueness and only serves heuristic for future research.

Educating Children in the Family Created in the Second Marriage in Today＇s Lithuania

Since the end of the twenty-first century, relationships in the family have been rapidly changing in Lithuania. The changes correspond to changes in the birth-rate. The former model of birth-rate which was characterized by the prevalence of legitimate children, child-bearing at a younger age and which ensured a change of generations, it was replaced by a new model characterized by having illegitimate children, the postponement of child-bearing, and low birth-rate, which does not ensure a change of generations. Although love relationships, marriage, and children are still considered to be the recognized values, these changes have affected the conception of child＇s education in the family and the perception of child as a value. It is therefore relevant to evaluate future spouses＇ preparation for a modern marriage and to constantly improve it. Such preparation is usually understood as young people＇s readiness far their first marriage. Readiness for the second marriage and child＇s education in the second family are no less important though still insufficiently explored empirically and theoretically generalized. This paper explores attitudes to child＇s education in the second marriage. The research was conducted inquiring people who wanted to create a family or establish long-term relationships. They were members of the online dating site ＂Harmonious Couple＂.
