In Skellig, Kit’s Wilderness, and Clay, David Almond employs various types of intertextuality to enrich his narratives. Through the use of allusion, adaptation,
collage, and mise-en-abyme, he encourages his adolescent readers to seek out precursor texts and to consider the interrelationships between these texts
and his own. By so doing, he demonstrates the respect he has for his readers and empowers them to become active makers of
meaning.

《我的马克思主义观》是李大钊成为马克思主义者的标志,是五四新文化运动的重要转折点,也是马克思主义在中国开始广泛传播的重要标志。有关论著对它的研究和提及很多,《李大钊全集》的编注者对其注解也较多。进一步研究起来,该文中需要探究的问题仍有不少。总起来看,李大钊的《我的马克思主义观》以日本社会主义学者河上肇的《马克思的社会主义理论体系》为重要蓝本,其关于马克思主义三个组成部分与一条“金线”的核心论断也出于河上肇此文;写作和定稿时间,应为1919年7月底到8月上旬,而不可能在1919年5月之前。 相似文献

This article argues that Philip Pullman’s His Dark Materials may be read as a series which attempts to assault the Christian doctrine of God. We believe that this demonstrably accords with Pullman’s personal views, and that, through his story, he seeks to foster such views in his readership. However, the accuracy of his attack falls short of its intended mark when it is examined alongside classical Christian theology. The Authority which Pullman’s narrative destroys is actually more akin to the Christian view of the devil than he is the divine, and the victories of Will and Lyra—as a new Adam and Eve—have strong resemblances to the victories which Christianity claims for Christ and Mary. Pullman’s narrative, therefore, becomes an inversion of his deicidal intention rather than an inverting and revolutionary destruction of theology.

AtCRE1 is known to be a cytokinin receptor inArabidopsis. TheAtCRE1 protein contains CHASE domain at the N-terminal part, followed by a transmitter (histidine kinase) domain and two receiver
domains. The N-terminal CHASE domain ofAtCRE1 contains putative recognition sites for cytokinin. Five CHASE domains containing proteins were found in rice,osCRL1a,OsCRL1b,OsCRL2,OsCRL3, andOsCRL4.OsCRL1a,OsCRL1b,OsCRL2 andOsCRL3 contain the four domains existing inCRE1, whereasOsCRL4 only contains the CHASE domain and a putative Ser/Thr protein kinase domain. The authors cloned the encoding geneOsCRL4 and found that it represents a new member of the cytokinin receptor protein in rice.

Peter Hollindale first developed critical interests in children's literature during postgraduate teacher training at the University of Bristol,
where he was taught by Margaret Meek. After teaching for several years in secondary schools he was appointed to the University
of York, where he is senior lecturer in English and educational studies. He now teaches an undergraduate special paper on
children's literature in the Department of English there. His bookChoosing Books for Children, a guide for parents, was published in 1974, and he has since written extensively on children's literature in academic and
professional journals. His article “Ideology and the Children's Book,” which appeared inSignal 55, received the Children's Literature Association Prize for the best essay in the field of children's literature published
in 1988. In recent years he has worked closely on J. M. Barrie. His edition of the “Peter Pan” prose texts was published by
Oxford University Press in 1991, andPeter Pan and Other Plays appears from the same publisher in 1995. He is interested in reworkings and adaptations of classic children's texts for film
and television, and his study of Steven Spielberg'sHook was published inSignal 72 in 1993. For Thimble Press he is currently completingSigns of Childness: A Short Philosophy of Children's Literature. He has contributed a number of articles toCLE, the most recent being “Westall's Kingdom” in the 1994 Autumn issue. 相似文献

One of the goals of genetics is to understand genes in as much detail as possible. For instance, with respect to a given gene,
one would like to know its chromosomal location, its physical and genetic size, its neighbours, the number of mutations/alleles
defining the gene, the order of mutations, the genetic/physical distance between them, etc. Thus, rather than focusing on
the whole genome, one focuses on the finer details of a given genetic segment. The exercise of probing such details is called
‘fine structure genetic analysis’. There are several pioneers who have contributed enormously to this area in many bacterial
and phage systems. Two stalwarts, Seymour Benzer and Charles Yanofsky, stand preeminent among them. In the following pages
I present briefly Benzer’s outstanding work on the fine structure of the rII region of bacteriopage T4. These path-breaking studies contributed significantly to our understanding of the structure,
organization and function of genes.

Cells and cell-free solutions of the culture filtrate of the bacterial symbiont, Xenorhabdus nematophila taken from the entomopathogenic nematode Steinernema carpocapsae in aqueous broth suspensions were lethal to larvae of the diamondback moth Plutella xylostella. Their application on leaves of Chinese cabbage indicated that the cells can penetrate into the insects in the absence of
the nematode vector. Cell-free solutions containing metabolites were also proved as effective as bacterial cells suspension.
The application of aqueous suspensions of cells of X. nematophila or solutions containing its toxic metabolites to the leaves represents a possible new strategy for controlling insect pests
on foliage. 相似文献

Objective: to explore a new serological method for detectingHelicobacter pylori (H. pylori) infection. Methods: Serum soluble antigen ofH. pylori was detected by using avidin-biotin ELISA technique to evaluate the status ofH. pylori infection and for comparison with rapid urease test (RUT), histologic examination and serology. Results: The sensitivity,
specificity, positive predictive value and negative predictive value were 77.46%, 91.07%, 91.67% and 76.12%, respectively.
The prevalence rate of serumH. pylori soluble antigen in 138 patients undergoing endoscopy was similar to the rate obtained by14C-UBT methods (P>0.05). Conclusions: The detection of serumH. pylori soluble antigen(HpSAg) could be used as a new serological method which is accurate, and convenient, not affected by the memorizing
reaction of serum antibody; is more sensitive, more specific and suitable for clinical diagnosis, and evaluation of eradication
and for follow-up ofH. pylori as well as for detection in children and pregnant women.

This two-part article considers certain fundamental symmetries of nature, namely the discrete symmetries of parity (P), charge conjugation (C) and time reversal (T), and their possible violation. Recent experimental results are discussed in some depth. In this second part, we discussCP andT violation and arrive at a synthesis. 相似文献

This paper proposes a new approach for multi-objective robust control. The approach extends the standard generalizedl
2 (Gl
2) and generalizedH
2 (GH
2) conditions to a set of new linear matrix inequality (LMI) constraints based on a new stability condition. A technique for
variable parameterization is introduced to the multi-objective control problem to preserve the linearity of the synthesis
variables. Consequently, the multi-channel multi-objective mixed Gl
2/GH
2 control problem can be solved less conservatively using computationally tractable algorithms developed in the paper.

Studies were conducted under pot conditions to determine the comparative efficacy of carbofuran at 1 mg a.i./kg soil, bavistin
at 1 mg a.i./kg soil, neem (Azadirachta indica) seed powder at 50 mg/kg soil, green mould (Trichoderma harzianum) at 50.0 ml/kg soil, rhizobacteria (Pseudomonas fluorescens) at 50.0 ml/kg soil against root-knot nematode,Meloidogyne incognita-wilt fungus,Fusarium oxysporum disease complex on green gram,Vigna radiata cv ML-1108. All the treatments significantly improved the growth of the plants as compared to untreated inoculated plants.
Analysis of data showed that carbofuran andA. indica seed powder increased plant growth and yield significantly more in comparison to bavistin andP. fluorescens. Carbofuran was highly effective against nematode, bavistin against fungus,A. indica seed powder against both the pathogens and both the bioagents were moderately effective against both the pathogens. 相似文献

AbstractAmong the most neglected of Albert Camus’ literary works is his play The misunderstanding. Composed while Camus was in exile in occupied France, and first performed on stage in 1944, The misunderstanding depicts the events that unfold when a man returns, without declaring his identity, to a home he left 20 years ago. Unrecognized, he is killed by his mother and sister for financial gain. This article draws on ideas from Emmanuel Levinas in identifying and discussing some of the key ethical and educational themes in the text. It is argued that the forms of misunderstanding evident in Camus’ play mirror those exhibited in pedagogical institutions such as schools. The misunderstanding demonstrates that what is often missing in our communicative relations is careful attention to the Other. Camus does not offer us any easy way out when confronting the impossibility of fully knowing ourselves and others; instead, he shows that we must acknowledge the suffering this brings and take responsibility for it. 相似文献

Insertion mutagenesis has become one of the most popular methods for gene functions analysis. Here we report a two-elementAc/Ds transposon system containing enhancer trap and gene trap for gene tagging in rice. The excision ofDs element was examined by PCR amplification. The excision frequency ofDs element varied from 0% to 40% among 20 F2 populations derived from 11 differentDs parents. Southern blot analysis revealed that more than 70% of excisedDs elements reinserted into rice genome and above 70% of the reinsertedDs elements were located at different positions of the chromosome in rice. The result of histochemical GUS analysis indicated
that 28% of enhancer trap and 22% of gene trap tagging plants displayed GUS activity in leaves, roots, flowers or seeds. The
GUS positive lines will be useful for identifying gene function in rice.

Three genes encoding for fungal cell wall degrading enzymes (CWDEs),ech42, nag70 andglu78 from the biocontrol fungusTrichoderma atroviride were inserted into the binary vector pCAMBIA1305.2 singly and in all possible combinations and transformed to rice plants.
More than 1800 independently regenerated plantlets in seven different populations (for each of the three genes and each of
the four gene combinations) were obtained. Theech42 gene encoding for an endochitinase increased resistance to sheath blight caused byRhizoctonia solani, while the exochitinase-encoding gene,nag70, had lesser effect. The expression level of endochitinase but exochitinase was correlated with disease resistance. Nevertheless,
exochitinase enhanced the effect of endochitinase on disease resistance when the two genes co-expressed in transgenics. Resistance
toMagnaporthe grisea was found in all kinds of regenerated plants including that with singlegluc78. A few lines expressing eitherech42 ornag70 gene were immune to the disease. Transgenic plants are being tested to further evaluate disease resistance at field level.
This is the first report of multiple of expression of genes encoding CWDEs fromTrichoderma atroviride that result in resistance to blast and sheath blight in rice.

Insecticidal effects of different doses of the dust and methanol extracts of Garcinia kolae on Collosobruchus maculatus and Sitophilus zeamais were tested. The dust had no significant effect on the two insects; none of them died even at 3 d after treatment. The methanol
extracts, however, had rapid lethal effects on both C. maculatus and S. zeamais. The mortality of C. maculatus by the lowest concentration of methanol extracts ranged from 95%∼100% whereas in S. zeamais, the mortality ranged from 87.5%∼100% and 70%∼100% in concentrations of 1 g extract+3 ml methanol and 1 g extract+5 ml methanol,
respectively, from 24 to 48 h. The least concentration of 1 g extract+15 ml methanol had no significant lethal effect on Sitophilus zeamais.

Fasciclin family proteins have been identified as cell adhesion molecules in various organisms. In this study, a novel Magnaporthe oryzae fasciclin-like protein encoding gene, named MoFLP1, was isolated from a subtractive suppressive cDNA library and functionally analyzed. Sequence analysis showed that the MoFLP1 gene contains an open reading frame (ORF) of 1050 nucleotides encoding 349 amino acids with a calculated molecular weight
of 35.85 kDa and a pI of 7.76. The deduced MoFLP1 protein contains a 17-amino acid secretion signal sequence and an 18-amino
acid sequence with the characteristics of a glycosylphosphotidylinositol (GPI) anchor additional signal at its N- and C-terminuses,
respectively. Potential N-glycosylation sites and domains involving cell adhesion were also identified in MoFLP1. Sequence analysis and subcellular
localization by the expression of MoFLP1-GFP fusion construct in M. oryzae indicated that the MoFLP1 protein is probably localized on the vacuole membrane. Two MoFLP1 null mutants generated by targeted gene disruption exhibited marked reduction of conidiation, conidial adhesion, appressorium
turgor, and pathogenicity. Our results indicate that fasciclin proteins play important roles in fungal development and pathogenicity
in M. oryzae.

In the biosphere we find cellulose and hemicellulose as the major polysaccharides. On acid or enzymatic hydrolysis,D-glucose is produced from cellulose andD-xylose is produced from xylans as the major sugar in the hydrolysate. Initially it was believed that yeasts do not fermentD-xylose to ethanol although many are capable of producing xylitol. Twenty years ago, a few yeasts that could convertD-xylose to ethanol were found. Ethanol is viewed as a potential fuel that is available from biomass and hence new methods
to generate ethanol from hitherto inaccessible sources are gaining importance. Biotechnology for efficient utilization of
lignocellulose wastes as fuels relies on the utilization of both the cellulosic as well as hemicellulosic portions of the
biomass. In this article, conversion of xylose into ethanol is discussed. 相似文献
