Abstract

The study was carried out at farmers fields to quantify nutrient harvest through biomass of pruned material of 2, 3, 4, 5 and 6 year old plantations and whole tree of Populus deltoides Bartr. (Poplar). The pruned biomass was 327.4, 426.96, 986.27, 1,234.91 and 1,558.59 kg ha^-1 at 2, 3, 4, 5 and 6 year old plantations respectively. The total biomass of branches, main stem and ischolar_main of poplar at exploitable age was 48,96, 89,144, 94,040 and 12,280 kg/ha, respectively. Nutrient concentration was increased from basal segment to terminal segment of pruned braches and decreased with size of the branches. The nutrient harvest through pruned biomass was 46.32 kg ha^-1 N, 6.92 kg ha^-1 P and 19.93 kg ha^-1 K whereas nutrient loss through whole tree was 652.8 kg ha^-1, 75.84 kg ha^-1 P and 719.84 kg ha^-1 K. As the nutrient is exceeded than annual return, additional doses of fertilizers may be required to maintain soil fertility and productivity of the system.

Abstract

This paper investigates the conversion of a rational polynomial in triangular Bernstein-Bézier form to polynomial in triangular Bernstein-Bézier form. We explore this problem from the point of view of CAD and numerical analysis. We investigate the following problem: Given a rational function (or curve) in triangular Bernstein-Bézier form, approximate it with a polynomial function (or curve) in triangular Bernstein-Bézier form such that the approximation error is minimized via Linear Programming Method (LPM). We also compare the developed method with other approaches.

Abstract

Field experiments on Happy seeder were conducted during 2009-10 and 2010-11 in farmer participatory research mode at different locations in the district Fatehgarh Sahib. The field experiments were conducted on 9 different locations to evaluate the operational performance of Happy seeder machine in context of heavy soils of district Fatehgarh Sahib, the effect of Happy seeder on wheat yield in heavy soils and to work out the economics of Happy Seeder as compared to farmer's practice. The study reveled that, the average reduction in weed count in happy seeder plots was 28% compared to conventional sown wheat. Wheat yield during these two years in 9 experiments was varied from 35.0 - 56.25 q/ha and 31.75 - 50.75 q/ha for Happy seeder and conventional seed drill plots, respectively with an average increase in yield of 8.84 % in Happy seeder plots.

Abstract

Two patients of snakebite with neurotoxic symptoms were evaluated for understanding the neurophysiological manifestations of snake venom by electrophysiological testing. The testing revealed evidence of neuromuscular junction dysfunction in both cases with decremental response. This response was more evident on higher stimulation rates indicating a post-synaptic defect distinctive from myasthenia gravis. EMG study in the first case provided a distinction between myokymia and fasciculations. Snake envenomation can often present as a myasthenic syndrome with ambiguous history and in such cases electrophysiology can give a clue to the diagnosis.

Abstract

Reported here is a case of 32 year old unmarried female presenting with altered sensorium and recurrent hypoglycaemia after a suspected high dose of insulin glargine with suicidal intent. Management of the patient in an intensive care setting with intravenous dextrose, subcutaneous glucagon injections and oral glucose rich diet produced effective results. The measurement of insulin and c-peptide levels helped confirm the diagnosis of insulin overdose.

Abstract

This study aims to present the management of a rare case of a separated endodontic instrument in the periradicular area. The broken instrument had penetrated within and along the mandibular canal from the periapical zone of mandibular second molar after endodontic treatment, leading to acute neurological symptoms. These subsided completely following surgical removal of the separated instrument. Because of the close anatomic relation between the second molars and the inferior alveolar nerve, careful clinical and radiographic examinations should always be performed before endodontic treatment of these teeth, so as to prevent iatrogenic injuries of the type described here. Dentists should also be aware of the anatomic characteristics of the mandibular canal (i.e., cribriform rather than solid), as well as the consequences of overinstrumentation.

Abstract

Objectives: In this paper, we apply the concept of pure fractions to create a mathematical model for the control of Thalassemia disease. Methods: The theory of pure fractions has generated various properties that make it suitable for formalizing the uncertain information upon which medical diagnosis and treatment is usually based. In this study we use pure fraction to generate a mathematical model for Thalassemia disease diagnosis. Findings: Thalassemia disease is one of the medical problems which could be controlled by premarital screening. This disease has major sign and symptoms in the first year of life. The objective of the work is to diagnose Thalassemia using pure fractions. The proposed model would help the health center to automate Thalassemia risk in future generation and to improve the medical care. Application: The proposed method is apply to various other genetic diseases such as G6PD deficiency etc.

Abstract

In this paper, we have provided one of the solutions for achieving ultra-low power goals. The technique used is Subthreshold region operation. This technique is useful in the applications where speed is of the secondary importance, and the low power requirement is of the prime concern. We have designed an ultra-low power sub-threshold circuits in which the voltage scaling is done below the threshold voltages. The reduction in energy consumption comes at the cost of the circuit performance. We analyzed the CMOS circuits in normal as well as sub-threshold regions and the results prove that there are orders of magnitude reduction in the power consumption.

Keywords

CMOS, Subthreshold Region, Ultra Low Power VLSI.

Abstract

In this paper we report that isoamyl alcohol and aniline are good inhibitor for SO₂ oxidation in pH range 4.02-5.25 in the presence of Ag(I). Based on the observed results following rate law given and a free radical mechanism has been proposed. d[S(lV)]/dt = (k₁+k₂[Ag(I)]) [S(lV)]/1 + B [Organics] Experiments were carried out at 30≤T°C≤40, 4.02≤pH≤5.25, 1×10⁻³ mol/cm³≤[S(lV)≤10×10⁻³ mol/cm³, 5×10⁻⁶ mol/cm³≤[Ag(I)]≤2.5×10⁻⁵ mol/cm³, 5×10⁻⁷ mol/cm³≤[Isoamyl alcohol]≤8×10^-3 mol/cm³,5×10⁻⁷ mol/cm³≤[Aniline]≤3×10^-4 mol/cm³. Rate constants and order of reaction were calculated and found pseudo- first order in all cases. The effect of pH and temperature were also discussed. The value of apparent energy were found as 45.16 kJ mol^-1 and 26.43 kJ mol^-1 in the presence of isoamyl alcohol and aniline respectively.
