Abstract

With a view to utilisation of enormous minespoil dumps from increasing opencast mining, for vegetational establishments, characterisation of these materials have been undertaken with special reference to nutrients and heavy metals. Pb, Mn, Fe, Cu, Co, Ni, Cr, B and Cd in the soil and also in the grains of 13 different crops in different seasons have been determined before and after cropping using an Atomic Absorption Spectrophotometer. Addition of ameliorating material, i.e., lime sludge from pulp and papermills have shown interesting results in the stabilisation of overburden material for cropping.

Keywords

Abstract

Electrophoretic mobilities of aqueous dispersions of pure graphite flakes, pure calcite mineral and pure quartz mineral were determined at a given ionic strength and at different pH's, in the absence and presence of additives. The calculated zeta potentials for the different systems were plotted against pH to understand the conditions of flotability/wettability.

Abstract

Last lecture delivery in a day is very challenging in all education systems. Lecture management involves lecture planning, learning objectives, teaching methods and classroom engagement. Lecture management is two_way communications between teacher and students. This paper deals by making a last lecture in a day energetic, "an experience in engineering institute. This paper shares an experience, to make the classroom teaching active and collaborative learning. The paper focused on outcome based education system for lecture management through students' involvement by active and collaborative learning methods.

Abstract

Dried arecanut are dehusked at farmer's house or at small scale processing units by manual labour using country kitchen tool having a wooden plank and curved MS blade. Traditional dehusking method is time consuming, highly labour intensive, uneconomical and above all very unsafe for fingers and palms. The developed pedal operated arecanut dehusker was evaluated with nine female workers to check the suitability of the machine for women workers. Average age, weight and stature of the subjects were 26.1(± 8.5) years, 46.7(± 9.6) kg and 158(± 6) cm, respectively. While average HR max and VO₂ max were 193.9 (±8.5) bpm and 1.47(± 0.3)l/min, respectively. The mean heart rate, oxygen consumption rate and energy expenditure rate for nine subjects were 136.6 bpm, 0.8 l/min and 16.56 kJ/min, respectively. The work is under 'Very heavy' category (Sen, 1969).

Abstract

The field experiment was conducted at agronomy field DBSKKV, Dapoli, on the traditional method of paddy transplanting and manual paddy transplanter. Eight male and seven female workers were participated in this activity. The mean working heart rate (WHR) during traditional method of paddy transplanting for male and female subject were 105.9 (±4.01) and 106.97 (±3.39) bpm, respectively, While mean WHR for male workers with manual paddy transplanter was 128.44 (±12.38) bpm. The field capacity for traditional method of paddy transplanting for male and female workers were 0.0040 ha/h (40 m²/h) and 0.0038 ha/h (38 m²/h), respectively. The workloads for male and female workers was "Moderately heavy" for traditional method of paddy transplanting. The field capacity and field efficiency with manual paddy transplanter were 0.020 ha/h and 47.75 per cent, respectively, with 21(DAS) nursery. The workload was "heavy" for manual paddy transplanter. Hence, the field capacity with manual paddy transplanter was 5 times more as compared to traditional method of transplanting. The working heart rate (WHR) with manual paddy transplanter for male workers was 0.82 more as compared to traditional paddy transplanting.

Abstract

This field experiment was conducted at Agronomy field, DBSKKV, Dapoli. Three different ages of nursery as 21, 28 and 35 DAS were taken for study. Plant and field parameters were measured during operation with manual paddy transplanter (hand cranked). The 21 (DAS) nursery required less time (25 min) for upischolar_maining and preparing ischolar_main washed seedlings from area of 1 m² as compared to that of for 28 (DAS) (35 min) and 35 (DAS) (42 min) nursery. Missing of hills were also less in 21 (DAS) nursery. The field capacity with existing manual paddy transplanter (hand cranking) was 0.020 ha/h for 21 (DAS) nursery, whereas, for 28 and 35(DAS) nursery it was found 0.018 ha/h and 0.019 ha/h, respectively. Hence, 21 (DAS) nursery was found suitable for manual paddy transplanter (hand cranking).
