Studies on the toxicity of Vacor (RH-787) on the reproductive biology of Rattus rattus rufescens

Vacor (RH-787), a relatively new rodenticide, was evaluated for the control of Rattus rattus rufescens. The symptoms of paralysis in hind limbs were observed after feeding it to rodents. The susceptibility to this rodenticide in Rattus rattus increased with the increase in its concentration. Experimental observations revealed that RH-787 bait with 0.0125% concentration affects the reproductive biology of the rats. Bait with 0.025% Vacor proved sublethal and within 5 days 70% mortality was observed, while 100% mortality was observed when rats were fed with 0.05% Vaco

Effect of paclobutrazol and benzyl adenine on oriental lily hybrids

Studies on the effect of growth regulators viz., Paclobutrazol and Benzyl Adenine (PBZ and BA, respectively) on Oriental Lily Hybrids, 'Star Gazer Pink' and 'Star Gazer White' in the second year were carried out at Department of Floriculture and Landscaping, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan (H.P). The effect of growth regulators applied in the first year, was studied on growth and flowering of Oriental lily hybrids in the second year. Plant height and number of leaves plant-1 were recorded maximum when PBZ 25 ppm was applied in the first year. Maximum plant height and number of leaves plant-1 were found in 'Star Gazer White' (84.46 cm; 35.04 cm). Bulbs of 'Star Gazer White' when dipped in PBZ 25 ppm for 12 h in the first year resulted in maximum plant height (102.50 cm) in the second year. Leaf area in the second year was recorded maximum in 'Star Gazer White' (34.40 cm2) when PBZ 50 ppm was applied as bulb dip in the first year. Flower buds were initiated earlier in 'Star Gazer White' (84.48 days) as compared to 'Star Gazer Pink' (85.90 days). Days to bud initiation were also recorded minimum (75.81 days) when PBZ 25 ppm was applied as pre-plant bulb dip. More number of flowers plant-1 was recorded in 'Star Gazer White' (5.42) which lasted longer on stems (16.77 days). Bulbs dipped in growth regulators in the first season produced maximum number of flowers plant-1 (5.72) and duration of flowering was also maximum (18.28 days)

Spectrophotometric Determination of Tantalum(V) with 5-Iodo-8-hydroxyquinoline-7-sulphonic Acid

Tantalum(V) reacts with 5-iodo-8-hydroxyquinoline-7-sulphonic acid to form a yellowish coloured complex having maximum absorbance at 405 nm in citric acid medium. The relatively slow reaction at room temperature is completed in 10 minutes at 40 °c. The colour is stable for at least 12 hr. Effects of heating temperature, time, pH, reagent concentration and other variables have been studied. The system confirms the Beer\u27s law over the concentration range investigated. The optimum condition range for measurement in 10 mm cell is 1-7.5 ~Lg of tantalum(V). The molar absorptivity is 5.753X104 mo1-1 dm2. The interference of foreign ions has been evaluated. The metal-ligand ratio of 1 : 2 was confirmed by the mole ratio method

Efficient Ultrasound Image Analysis Models with Sonographer Gaze Assisted Distillation.

Recent automated medical image analysis methods have attained state-of-the-art performance but have relied on memory and compute-intensive deep learning models. Reducing model size without significant loss in performance metrics is crucial for time and memory-efficient automated image-based decision-making. Traditional deep learning based image analysis only uses expert knowledge in the form of manual annotations. Recently, there has been interest in introducing other forms of expert knowledge into deep learning architecture design. This is the approach considered in the paper where we propose to combine ultrasound video with point-of-gaze tracked for expert sonographers as they scan to train memory-efficient ultrasound image analysis models. Specifically we develop teacher-student knowledge transfer models for the exemplar task of frame classification for the fetal abdomen, head, and femur. The best performing memory-efficient models attain performance within 5% of conventional models that are 1000× larger in size
