The aim of the study was to ascertain the role of ethanolic extract of Cynodon dactylon against hepatic complications in streptozotocin
(STZ) induced type 2 diabetic models. Effect of the pre identified most effective dose of 500 mg/kg body weight was studied
on hepatic injury caused by chemically induced diabetes by 55 mg/kg body weight i.p. injection of STZ in male Wistar rats.
The dose of 500mg/kg body weight given once daily for 14 days reduced the levels of serum glutamate oxaloacetate transaminase,
serum glutamate pyruvate transaminase, alkaline phosphatase, creatinine and urine sugar significantly (P<0.05) with increase
in total protein, haemoglobin and body weight was increased. High LD50 validates its high margin of safety. 相似文献

A large class of visual servo controllers relies on an a priori obtained reference image, captured at the desired position and orientation (i.e., pose) of a camera, to yield control signals to regulate the camera from its current pose to a desired pose. In many applications, accessibility and economics of the operation may prohibit acquisition of such a reference image. This paper introduces a new visual servo control paradigm that enables control of the camera in the absence of reference image using a set of terminal constraints. Specifically, the desired pose is encoded using the angle of obliquity of the optical axis with respect to the object plane and its direction of arrival at the plane. A constrained convex optimization problem is formulated over a conic section defined by the terminal constraints to yield an error system for the control problem. Subsequently, this work introduces continuous terminal sliding mode visual servo controllers to regulate the camera to the desired pose. Lyapunov-based stability analysis guarantees that the origin is a finite-time-stable equilibrium of the system. Numerical simulation results are provided to verify the performance of the proposed visual servo controller. 相似文献

This study focused on the relationships between host national (host interpersonal communication) and home national (ethnic interpersonal communication) involvements and preferences for conflict management styles in the context of a conflict with a member of the host culture. Two hypotheses that examined the relationships between these variables and the preferences for the integrating, the compromising, the avoiding, the obliging and the dominating styles were proposed. Survey data from two hundred and sixty-nine, international and exchange, students were analyzed. The results revealed that the level of host national involvement positively predicted the preferences for the integrating and the obliging styles, and the level of home national involvement positively predicted the preference for the avoiding style. These findings suggest the need to consider contextual influences in understanding the complexities that underlie intercultural communication and adaptation. 相似文献

This study analyzed coverage of the shootings of two journalists in Virginia in 2015. Coverage of journalism by journalists, or metajournalistic discourse, makes it possible to examine the way an interpretive community represents and reproduces professional norms. Working with the framework of Pierre Bourdieu's field theory, the analysis considers the way journalistic specialists maintain their identity, professional boundaries, and hierarchal relationships. This analysis focuses on how visual journalism, in particular, is presented to the news audience. Based on our findings, we argue that coverage of the Roanoke live-shot murders provides insight into the way journalism maintains its authority by highlighting affect and diminishing its constructed dimension. 相似文献

A dual S shaped micro strip antenna with a realistic feed is proposed for generation of tilted beam radiation pattern pertaining for beam steering applications. To achieve this, four feeding points are located at a distance of 5.6 mm from the antenna centre. These feeding points when excited one by one generate four tilted beams in four different space quadrants, thus yielding a beam steerable antenna. Importantly, since the proposed antenna is symmetrical in the structure, all the four tilted beams have the same radiation pattern characteristics. A further enhancement of the antenna bandwidth is also achieved using 100-μm capacitive coupling between the feed and the antenna strip. 相似文献

We explored teachers’ views and students’ experiences of going beyond the syllabus in Advanced (A) level Mathematics. Questionnaires were sent to teachers and students in a sample of 200 schools and colleges. Teachers were asked about the necessity, importance and benefits of additional teaching. Students were asked about the extra activities they undertook. Forty-seven teacher questionnaires and 299 student questionnaires were completed. Over half of the students claimed to undertake at least some extra activities. Although a few teachers thought teaching beyond the syllabus was unimportant and unnecessary, over 70% felt it should be undertaken if time allowed. Teaching efficacy was measured by comparing each teacher’s students’ Mathematics results with those students’ results in other A level subjects. Significantly more teachers with relatively high Mathematics results than with relatively low results believed teaching beyond the syllabus strengthens and expands students’ existing knowledge and adds interest to the course. 相似文献

It is now widely acknowledged that the Bush administration used faulty and false information to justify the 2003 war on Iraq, and that the mainstream media, by not adequately investigating the case for war, assisted with the project. In this paper, I outline the particular strategies employed by the media–military industrial complex to ensure a dominance of pro-war arguments in the public sphere. I conclude by arguing that the failure of the media in the US to meet the democratic needs of this society places enormous responsibility on intellectuals to produce scholarship critical of the new imperialism. 相似文献
