Dissipation of pencycuron in rice plant     

Pal R  Chakrabarti K  Chakraborty A  Chowdhury A 《Journal of Zhejiang University. Science. B》2005,6(8):756-758

INTRODUCTION Pencycuron [1-(4-chlorobenzyl)-1-cyclopentyl- 3-phenylurea], a relatively new non-systemic protec-tive fungicide for controlling sheath blight (Rhizoc-tonia solani) of rice (Sylvanie and Cornis, 1989; Tomlin, 1997), is expected to be used widely in ag-ricultural production particularly in Asia. However, information on the dissipation pattern of pencycuron in rice plant is lacking. Little information on the en-vironmental fate of pencycuron has been published although there …  相似文献

A closer look at the Mulliken-Barker test     

Kaushik Basu  Suchandra Chakraborty  Chandan Saha 《Resonance》2013,18(9):845-848

Qualitative analysis of unknown organic compounds is an essential part of the core curriculum for BSc and MSc students in chemistry. The functional group detection is a significant component of qualitative analysis. The present work describes the reason for the failure of Mulliken-Barker test for nitro compounds having carboxylic acid functionality and suggests a possible remedy.  相似文献   

Study of oxidative stress in obsessive compulsive disorder in response to treatment with Fluoxetine     

Sutirtha Chakraborty  Anindya Dasgupta  Harendra Nath Das  Om Prakash Singh  Asok Kumar Mandal  Nikhiles Mandal 《Indian journal of clinical biochemistry : IJCB》2009,24(2):194-197

Oxidative stress has been found to play important role in several neuropsychiatric diseases including Obsessive Compulsive Disorder. A longitudinal case control study was conducted to evaluate the oxidative stress in 30 newly diagnosed obsessive compulsive disorder patients and same number of control patients. Serum thiobarbituric acid reacting substances, plasma ascorbate were assessed to evaluate oxidative stress and Yale Brown obsessive compulsive scale for disease severity before and after treatment with Fluoxetine at the average dosage of 40 mg/day. Improvement in Yale Brown obsessive compulsive scale score by about 43% after 12 weeks treatment was associated with significantly decreased thiobarbituric acid reacting substances and increased plasma ascorbate values (p < 0.05). The newly diagnosed obsessive compulsive disorder patients had higher serum thiobarbituric acid reacting substances as well as a lower plasma ascorbate levels than the control population. Thus, the present study suggested a significant role of oxidative stress in obsessive compulsive disorder and showed that a successful treatment with Fluoxetine not only improves the clinical scenario but also reduces the oxidative stress that may further improve the prognosis of the disease.  相似文献   

Promoting Integration of Multiple Texts: a Review of Instructional Approaches and Practices     

Sarit Barzilai  Asnat R. Zohar  Shiri Mor-Hagani 《Educational Psychology Review》2018,30(3):973-999

The ability to meaningfully and critically integrate multiple texts is vital for twenty-first-century literacy. The aim of this systematic literature review is to synthesize empirical studies in order to examine the current state of knowledge on how intertextual integration can be promoted in educational settings. We examined the disciplines in which integration instruction has been studied, the types of texts and tasks employed, the foci of integration instruction, the instructional practices used, integration measures, and instructional outcomes. The studies we found involved students from 5th grade to university, encompassed varied disciplines, and employed a wide range of task and text types. We identified a variety of instructional practices, such as collaborative discussions with multiple texts, explicit instruction of integration, modeling of integration, uses of graphic organizers, and summarization and annotation of single texts. Our review indicates that integration can be successfully taught, with medium to large effect sizes. Some research gaps include insufficient research with young students; inadequate consideration of new text types; limited attention to students’ understandings of the value of integration, integration criteria, and text structures; and lack of research regarding how to promote students’ motivation to engage in intertextual integration.  相似文献

Characteristics and Difficulties of Teachers Who Mentor Environmental Inquiry Projects   总被引：1，自引：0，他引：1  

Revital??TalEmail author  Sarit?Argaman 《Research in Science Education》2005,35(4):363-394

The paper describes characteristics and analyses difficulties of environmental sciences teachers in mentoring their students in an extended inquiry project, which is a mandatory requirement of the environmental sciences matriculation in Israel. The teachers participated in a professional development program that provided both content knowledge and support for conducting inquiry, and enabled the teachers to guide the students in the inquiry project. Teachers who had experience in inquiry identified more skills required for mentoring students' inquiry, and provided a non-directive guidance pattern, whereas inexperienced teachers acknowledged less skills, and tended to present a directive-authoritative approach. Insufficient content and pedagogical content knowledge affected the teachers who closely controlled their students' work.  相似文献   

The Curtin-Hammett principle     

Suchandra Chakraborty  Chandan Saha 《Resonance》2016,21(2):151-171

This article qualitatively discusses the Curtin-Hammett principle without mathematical treatment of the kinetic model. We show how the practical application of this principle can be extended to tautomers of several compounds and to explain the diazotization of aniline. The concept of ‘kinetic quenching’ is also discussed as a system where the Curtin-Hammett principle is inapplicable.  相似文献
