Water hyacinth (Eichhornia crassipes (Mart.) Solms) is a prolific free floating aquatic macrohpyte found in tropical and subtropical parts of the earth. The effects
of pollutants from textile wastewater on the anatomy of the plant were studied. Water hyacinth exhibits hydrophytic adaptations
which include reduced epidermis cells lacking cuticle in most cases, presence of large air spaces (7∼50 μm), reduced vascular
tissue and absorbing structures. Textile waste significantly affected the size of root cells. The presence of raphide crystals
was noted in parenchyma cells of various organs in treated plants.

Currently, all elite high jumpers use the Fosbury Flop technique with a curved approach. This suggests that the curved approach presents some clear advantage, although there is no general agreement upon the mechanism or the mechanics. This study aimed to determine the characteristics of the approach curve and to investigate how it contributes to the generation of somersault rotation. A simple theoretical model was used to demonstrate that a tightening approach curve would change the inward lean towards the centre of the curve into outwards lean. Three-dimensional video analysis was used to record the performances of two elite male high jumpers in competition. It was found that in each case the radius of the approach curve and the inward lean angle both decreased towards the end of the approach. The amount of outward lean angular velocity generated was shown to be a major proportion of the required somersault angular velocity for a jump. It was concluded that the main advantage of a curved approach was that it resulted in the generation of somersault velocity providing the curve tightened towards the end of the approach. 相似文献

Serum and urine samples from 513 patients clinically suspected of monoclonal gammopathies over a period of five years (1992–97)
were subjected to various immunological procedures viz, electrophoresis, immunoelectrophoresis and immunoglobulin estimations.
Laboratory investigations confirmed gammopathies in 10.33%. It was observed that overall age of incidence for monoclonal gammopathies
in both sexes was between 42–72 years with a male to female ratio of 1.4∶1. Predominant paraprotein detected was IgG type
(75.47%) followed by IgA (16.98%) and Bence Jones proteins (7.55%). Amongst positive patients, 64.16% were having kappa (k) type light chains and 35.84% lambda (δ) type light chains. 69.39% patients with serum M component (IgG and IgA) had Bence
Jones proteinuria. Densitometric scanning revealed that majority of IgG type paraprotein was found in the slow gamma globulin
region and majority of IgA type paraprotein was found equally distributed between beta and fast gamma globulin regions. Both
types had decreased albumin and alpha-2-globulin concentrations as compared to normal controls. Immunoglobulin levels in patients
with paraprotein had very high levels of serum IgG (6467.0 mg%) and IgA (2714.0 mg%) in respective types of monoclonal gammopathies;
the rest of immunoglobulin classes were either at normal or decreased levels. 相似文献

Pleural effusion is one of the commonest presentations of tuberculosis, the clinical manifestations being typically abrupt
resembling bacterial pneumonia. Since delayed hypersensitivity is the underlying immune response, bacterial load is very low.
Owing to these facts, tuberculous pleurisy as an extra-pulmonary disease poses a diagnostic dilemma. The conventional bacteriological
methods rarely detect Mycobacterium tuberculosis in pleural fluid and are of limited use in diagnosis of tuberculous pleurisy.
We evaluated the efficacy of polymerase chain reaction (PCR) in the diagnosis of tuberculous pleurisy by targeting the gene
segment coding for MPB64 protein specific forMycobacterium tuberculosis. Based on the clinical criteria, 82 patients with lymphocytic exudative pleural effusion were included in the study. Patients
were analyzed in two groups; one group consisting of 48 patients of tubercular pleural effusion confimed by various diagnostic
procedures and another group of 34 patients comprising of non-tubercular pleural effusion. There were no false positive results
by PCR and the specificity worked out to be 100%. Twenty two patients tested positive for Mantoux with a sensitivity of 45%.
ZN-staining for AFB was found in samples from 15 patients (20% sensitivity). ADA was positive for 28 patients with a sensitivity
of 53%. PCR was positive for 32/48 patients (67% sensitivity). Thus, PCR was found to be more sensitive than any other conventional
method in diagnosis of clinically suspected tubercular pleurisy. 相似文献

This paper aims to identify the gaps in management education highlighted by 3 primary stakeholders： students, faculty and alumni. The study tries to address the issue of relevance and compatibility of management education and investigates areas of improvement perceived by respondents. The paper assumes that business departments of universities have to bring changes in learning strategies to meet the requirements of stakeholders. This research takes UMT （University of Management and Technology） as a case study and presents gaps in management education. Data are collected from all the 3 stakeholders： students, faculty and alumni of MBA （Master in Business Administration） program offered at UMT. The survey is administered using an exclusively-designed research instrument and the data set of 211 students, 55 faculty members and 145 alumni is analysed using appropriate statistical techniques. The management of business schools should develop an integrated and well-coordinated mechanism to share common vision and strategies among stakeholders. A need to revise current MBA curriculum is identified, which emphasizes on the development of different types of skills among MBAs to make the program compatible with the existing corporate sector. The universities dealing in management education are recommended to redesign their curriculum in a more integrated and coordinated way in anticipation with aspiration of the existing corporate sector, which would then help reduce the identified gaps among stakeholders. The management of business schools should have a continuous assessment mechanism incorporating the feed back of all stakeholders, particularly students, faculty and alumni. The paper makes a fruitful contribution to the existing academic literature through an empirical investigation in Pakistani environment. A critical discussion is carried out, and gaps in management education are highlighted, which may motivate management institutions to revise their curriculums. 相似文献
