The extraordinary romance and thrilling adventure associated with the tale of wootz steel shows how Indian metallurgists were
the world leaders in antiquity in the manufacture of this legendary high-grade steel. In many ways this material was brought
to global attention by the writings of Cyril Stanley Smith. Modern metallurgy and materials science rest on the foundation
built by the study of this steel during the past three centuries. 相似文献

The level of seven acute phase proteins was estimated together with copper and zinc in two groups of 15 children each suffering
from hepatitis A (HAV) or Hepatitis B (HBV). The mean concentration of α-1 antitrypsin, α-2 macroglobulin, ceruloplasmin,
C3 and copper was increased uniformly in both the types of viral hepatitis. α-1 acid glycoprotein, haptoglobin and zinc levels
were decreased in both the infections. A significant decrease in albumin level was observed in HAV while the decrease was
not significant in HBV. All the paramenters were repeated after one month on the day of discharge following the disappearance
of clinical signs and symptoms wherein the haptoglobin level returned to normal in HAV. No change was observed in the level
of other acute phase proteins. The level of the trace elements returned to normal. The observed increase in the levels of
acute phase proteins at the onset does not seem to have any significant relation to the subsequent course of the disease.
However, the level of acute phase proteins and other biochemical parameters may indicate a delayed biochemical recovery phase
in conjunction with the underlying hepatic pathological changes in the course of viral hepatitis in spite of clinical recovery. 相似文献

Russell Hoban has compared himself as a writer to a shaman—willing to admit the unseen and making himself a medium for the
quality of the unseen in his novels. This article explores Hoban’s highly-regarded The Mouse and His Child (1967) with this comparison in mind. The writer interweaves Mircea Eliade’s study of shamanism with an examination of the experiences
of the protagonists of the novel—The Mouse and His Child. In so doing, she reveals many elements of shamanism in the text which, it is argued, reaches a conclusion which is consistent
with the central tenets of the Indian philosophical system of Advaita.

We report an exploratory talk based, whole class plenary intervention, in relation to students’ understanding of everyday measures and measurement, in a grade four classroom at a grade 4–6 school in Sweden. Extended, project related, teacher-researcher collaboration forms basis for such cultural historical activity theory or CHAT based efforts. As formative intervention, the conduct of the plenary is not pre-determined but embedded in ongoing curricular realities, with the agency of students and teacher promoted, pedagogical ideas reutilised and the role of researcher viewed as supporting design and growth of the intervention. Under Charlotta’s guidance as teacher, the plenary is opportunity for her students to examine improbable scenarios such as, Can Eva and Anton measure the length of Sweden on foot, Can Lars and Iris measure their age in decimeters. A zone of proximal development is created, in which students make the transition from spontaneous to scientific concepts and learn how various units of measurement are objects-that-can-be-used-for-certain-purposes. With opportunity for critical and reflective inquiry, in a plenary designed to lead development, Charlotta’s students look beyond the making of rote measurements and articulate a theory of measure in nascent terms. Such a landscape of teaching–learning is finally understood in terms of the nature of talk that was facilitated, the manner of pedagogy utilised, the style of teaching exercised and the kind of learning that was demanded of her students. 相似文献

Long association with a mathematics teacher at a Grade 4–6 school in Sweden, is basis for reporting a case of teacher–researcher collaboration. Three theoretical frameworks used to study its development over time are relational knowing, relational agency and cogenerative dialogue. While relational knowing uses narrative perspectives to explore the experiential and relational nature of collaboration; relational agency, draws on activity theory perspectives and identifies the change in the purpose of collaboration, from initially conducting classroom interventions to co-authoring research. Finally, cogenerative dialogue, deploys hermeneutic-phenomenological perspectives and investigates the dialogue that transpired between Lotta and the author, as they co-authored their research report. Such analysis sheds invaluable light on a case of expansive learning activity. 相似文献

Serum cardiac troponin T (cTnT) and CKMB (mass) were analysed in three groups of patients. The first group (n=32) were patients
with acute coronary syndromes including myocardial infarction. The second group (n=35)were patients with hypertension. The
third group (n=24) were patients who had succumbed to non cardiac diseases. In all 3 groups, cardiac troponin T was elevated
when compared with controls (p<0.001). However, CKMB elevation was not significant in all groups. CKMB levels correlated well
with troponin T levels only when CKMB was greater than 50 ng/ml (r=1.00). Small elevations of troponin T identifies minimal
cardiac necrosis and patients can benefit from early invasive therapy. 相似文献
