菊芋,又名洋姜(或洋芋头)。用地下茎繁殖,地下茎含丰富的淀粉和糖类。可以熟食,也可以作成菜。它的茎较高,花是黄色,很象菊花,秋季盛开,逗人喜爱。 向日葵用种子繁殖,春天播种,秋季收获。在学校或家里种一些向日葵,即可食用,又可美化环境。 在种菊芋和向日葵的过程中,我们发现它们的根、茎、叶、花形态相似,但它们之间又有很多区别。菊芋用地下茎繁殖,而向日葵靠种子来繁殖;它们的茎的粗细高矮都不同,菊芋的茎较细,茎高一般在一米左右,而向日葵 相似文献

通过设置3组实验组和3组对照组,研究污泥和尿素对小麦秸秆厌氧发酵的影响。以100g小麦秸秆为发酵原料,当3组实验组中接种河塘污泥分别为20g,30g,40g时,累积产气量分别为1429ml,2163ml,2544ml,平均日产气量分别为59.54ml,80.10ml,94.20ml。分别添加2.0g尿素后,累积产气量分别为3521ml,4322ml,5209ml;平均日产气量分别为140.84ml,166.20ml,192.90ml。结果表明,随着污泥接种量的增加,实验组和对照组小麦秸秆发酵累积产气量均显著增加。同时,3组实验组均在实验第一天没有产气,第27天产气结束。3组对照组均在第一天有产气,第25天产气结束。结果表明,添加尿素,对提高小麦秸秆发酵产气量,缩短秸秆发酵周期具有重要作用。 相似文献

The article investigates the migration of Palestinian Muslim women, citizens of Israel, to the Hebrew University in Jerusalem or to Jordanian universities for academic studies, and the influence of this migration on their norms, behavior and identity. Narrative interviews were conducted with Palestinian Muslim women graduates: eight from the Hebrew University, Jerusalem and eight from Jordanian universities. Findings revealed that the women’s migration from their home communities to academic campuses involves issues of affiliation and identity; studies in Jordan constitute temporary cyclic emigration between two safe spaces, while studies in Jerusalem often involve alienation and foreignness. In both cases, higher education is a powerful force shaking up women’s lives. Following graduation, Hebrew University graduates remain in Jerusalem’s environs and migration to Jerusalem may become permanent. Higher education enables these women to engage with and confront identity issues, empowering them to reconsider their value and belief systems and relations with others. 相似文献

Objectives: To explore the mechanism of development and aggressiveness in gastric carcinomas by investigating the expression and role of CD97 and its cellular ligand CD55 in gastric carcinomas. Methods: Tumor and corresponding normal mucosal tissue, collected from 39 gastric carcinoma patients, were examined by immunohistochemistry and RT-PCR for the expression of CD97 and CD55. Results: CD97stalk was strongly stained on scattered tumor cells or small tumor cell clusters at the invasion front of gastric carcinomas. The expression of CD97stalk was frequently observed in tumors of stage Ⅰ and T1 gastric carcinoma patients. The expression of CD97stalk between Stage Ⅰ and Stage Ⅱ, Ⅲ, Ⅳ specimens showed significant difference (P＜0.05), between T1 and T2, T3, T4 specimens also showed significant difference (P＜0.05). Specimens with tumor invasion depth limited in mucosa of T 1 specimens showed higher positive CD55 expression than specimens with the same tumor invasion depth in T2, T3, T4 specimens, the expression of CD55 between T1 and T2, T3, T4 specimens was significantly different (P＜0.05).There was strong correlation between the distribution patterns of CD97stalk and CD55 on tumor tissues (r=0.73, P＜0.05). Signet ring cell carcinomas frequently contained strong CD97stalk and CD55-staining. Conclusions: Our results suggest that CD97stalk is probably involved in the growth, invasion and aggressiveness of gastric carcinomas by binding its cellular ligand CD55. CD97stalk and CD55 could be useful as molecular markers for prognosis and therapy of gastric carcinoma patients. 相似文献

The article describes and evaluates an innovative experiment in education and training of social workers at an academic learning center, which was established by the Hebrew University's School of Social Work and Social Welfare in a neighborhood of Jerusalem. The project focused on strengthening the link between theory, research, and practice. Participants were exposed to advanced theories and macropractice seminars, and gained practical experience as well as tools and technologies for coping with the social problems faced by Jerusalem neighborhoods. In that process, they became aware of the difficulties involved in initiating programs and in establishing coalitions with neighborhood institutions, residents, and other constituencies. The article deals with the achievements of the learning center, as well as with the difficulties and dilemmas encountered in the effort to sustain collaboration between the university and the community. In addition, issues related to supervision of students specializing in community work and practice, and implications for social work education are presented and discussed. 相似文献

The study of traditional Jewish texts is perhaps the single most critical and engaging activity in Jewish education. Students spend the greater part of their classroom time delving into this source material, much of it ancient, some of it recent, in order to gain a better understanding of their heritage and how it relates to them in profound and in routine ways. Jewish educators are deeply aware of the importance of textual study in the curriculum, and it is their concern and their children's needs that were addressed by the 1987 Conference on Jewish Texts, sponsored by the Melton Center at the Hebrew University in Jerusalem. More than 20 educators and psychologists were invited to Jerusalem from widely scattered sites, mostly North American and Israeli, to attend a series of meetings where some presented and all discussed the papers that appear in the present volume. The statements range in substance from the philosophical to the pedagogical and from the original to the traditionally derivative interpretation of textual sources in educational contexts. All are intended to bring a fresh perspective on issues that are as old and vital as Jewish education per se. 相似文献

The Home Instruction Program for Preschool Youngsters (HIPPY) is a home-based program in which paraprofessionals from the community teach parents how to use structured educational materials to enrich the education of their four- and five-year-old children. HIPPY was developed in 1969 by Dr. Avima Lombard of the National Council of Jewish Women Research Institute at the Hebrew University of Jerusalem. It has since become a national program in Israel for disadvantaged families and their preschool children.Arlene Brett is Associate Professor in the School of Education, University of Miami, Coral Gables, FL 相似文献

It is Only in recent years that the systematic study of Jewish educational systems, particularly in a global context, has become a subject of serious concern. Since 1945 a succession of education conferences and surveys provides evidence of an awareness that the future of World Jewry—in Israel as well as the Diaspora—is inextricably linked with the future of its educational institutions. The World Conference on Jewish Education in Jerusalem in 1962 and the subsequent formation two years later of the World Council on Jewish Education are but two examples of this awareness. The establishment of a Center for Jewish Education in the Diaspora at the Hebrew University in Jerusalem marks a further practical step toward attaining some form of coordination on the part of world Jewry. 相似文献

This paper presents a Structured Integrative Model (SIM) of individual mental health consultation. SIM is based on the problem-solving approach to mental health consultation, while integrating principles from dynamic and cognitive therapies. The model evolves through four stages: Building the Contract, Searching for New Understanding, Applying the New Understanding to Intervention, and Evaluating the Results. The SIM places special emphasis on the different functions, responsibilities, and possible contributions of the consultee and the consultant, as two active and equal partners working towards a common goal.This paper was supported by a grant from the Sturman Center for Human Development, The Hebrew University of Jerusalem. 相似文献
