  The aim of the present study was to investigate the variation in soil mycobiota involved in the decomposition of Sesbania aculeata L. in soil. Decomposition of Sesbania aculeata (Dhaincha) was studied by nylon net bag technique under experimental conditions. The colonization pattern by soil inhabiting mycobiota was studied by standard methods. Among the three methods used for isolation and enumeration of fungi, dilution plate technique recorded the highest number of fungi followed by damp chamber and direct observation method. Nutrient availability and climatic conditions influenced occurrence and colonization pattern of mycobiota. Maximum fungal population was recorded in July (48.95±0.20x104 of fungi/g oven dry litter) and minimum in June (19.78±0.20x104 of fungi/g oven dry litter). The distribution of Deuteromycetous fungi was much more (74.47%) than Zygomycetes, Oomycetes and Ascomycetes. In the early stage of decomposition Mucor racemosus, Rhizopus stolonifer, Chaetomium globosum and Gliocladium roseum were found where as at the later stages of decomposition preponderance of Aspergillus candidus, Cladosporium cladosporioides, Curvularia lunata and Aspergillus luchuensis was recorded.

  The aim of the present study was to check the efficacy of carbendazim 50% WP, antagonists and botanicals against Fusarium oxysporum f. sp. psidii associated with rhizosphere soil of guava. Guava (Psidium guajava L.) the apple of tropics is one of the most important fruit in India. The fruit of guava is a good source of vitamin C and pectin. Guava wilt is a serious disease and it recognized as a main causal organism. Isolation and identification of pathogen (Fusarium oxysporum f. sp. psidii) was carried out in the Department of Plant Protection, Allahabad Agricultural institute Deemed University, Allahabad. The radial growth of Fusarium cxysporum f. sp. psidii was fully inhibited at high concentrations like 100, 1000 and 10,000 ppm of cardendazim 50% WP whereas antagonists like Trichoderma spp. Produced maximum inhibition zone (61.91%) followed by Aspergillus niger (61.12%). The radial growth of Fusarium cxysporum f. sp. psidii was also significantly less in neem leaf extract treatment followed by Lantana leaf extract. Management of guava wilt by chemical (systemic fungicide) can be spectacular but this is relatively short-term measure. Eco-friendly management practices, i.e., use of bio-control agents and botanicals was studied in vitro which gave better results and these practices can be economical, long lasting and free from residual side effects.

In this paper we use insights from Sraffa's classic, Production of Commodities by Means of Commodities, to argue that the classical notion of ‘centre of gravitation’ is not a sound concept. The market mechanics of labour allocation through price signals and quantity adjustments, given effectual demands, do not lead to a ‘centre of gravitation’. We work out all such possible market mechanisms, including the specific classical case, and show that the ‘centre of gravitation’ is a non-attractive point in all cases.

Aims

It has been proposed that the Chronic Kidney Disease Epidemiology Collaboration formula estimates glomerular filtration rate more accurately than the Modification of Diet in Renal Disease formula. With the very high incidence of diabetes and end-stage kidney disease in Indigenous Australians, accurate estimation of glomerular filtration rate is vital in early detection of kidney disease. We aimed to assess the performance of the Chronic Kidney Disease Epidemiology Collaboration, Modification of Diet in Renal Disease and Cockcroft-Gault formulas in Indigenous Australians with and without diabetes.

Methods

Indigenous Australians with (n = 224) or without (n = 340) Type 2 diabetes had a reference glomerular filtration rate measure using plasma disappearance of iohexol (measured glomerular filtration rate) over 4 h. Serum creatinine was measured by an enzymatic method. Performance was assessed by bias (measured glomerular filtration rate - estimated glomerular filtration rate) and accuracy (percentage of estimated glomerular filtration rate within 30% of measured glomerular filtration rate).

Results

The median measured glomerular filtration rate (interquartile range) in participants with or without diabetes was 97 (68-119) and 108 (90-122) ml min−1 1.73 m−2, respectively. The Chronic Kidney Disease Epidemiology Collaboration formula had smaller bias and greater accuracy than the Modification of Diet in Renal Disease and Cockcroft-Gault formulas overall, for participants both with and without diabetes. However, for estimated glomerular filtration rate > 90 ml min−1 1.73 m−2, the Chronic Kidney Disease Epidemiology Collaboration formula had greater bias in participants with diabetes, underestimating measured glomerular filtration rate by 7.4 vs. 1.0 ml min−1 1.73 m−2 in those without diabetes. The Chronic Kidney Disease Epidemiology Collaboration formula was less accurate across the whole range of estimated glomerular filtration rates in participants with vs. those without diabetes (87.1% vs. 93.3%).

Conclusions

The Chronic Kidney Disease Epidemiology Collaboration formula outperforms the Modification of Diet in Renal Disease and Cockcroft-Gault formulas overall in Indigenous Australians with and without diabetes. However, the Chronic Kidney Disease Epidemiology Collaboration formula has greater bias in people with diabetes compared with those without diabetes, especially in those with normal renal function.

  In present study effect of Mungbean yellow mosaic virus on the chlorophyll, total nitrogen, protein, total phosphorous and carbohydrate content in three varieties of mungbean plants HUM -2 (Malviya Jagriti), ML-192, Pusa Baisakhi were studied. Total chlorophyll, chlorophyll a, chlorophyll b content and carbohydrate content were lower in virus infected mungbean plant varieties. Total nitrogen, protein increased and total phosphorous content was found to be high in virus infected mungbean leaves. Estimation of chlorophyll in healthy and diseased leaves of mungbean plants at 15, 30, 45, 60 and 75 days were done and absorbance were recorded by spectrophotometer at 663 and 645 nm. Total nitrogen of leaves was measured by modified microkjekldahl method and total protein content was determined by multiplying the total nitrogen content with 6.25. Total phosphorous were estimated by digestion with Tri-acid mixture and reading was taken in spectrophotometer at 470 nm. Determination of carbohydrates were done by total water soluble sugars and starch content.
