Development of a fiber optic compressor blade sensor

A complete working prototype of the fiber optic blade tip sensor was first tested in the laboratory, followed by a thorough evaluation at NASA W8 Single Compressor Stage Facility in Lewis Research Center. Subsequently, a complete system with three parallel channels was fabricated and delivered to Dr. Kurkov. The final system was tested in the Subsonic Wind Tunnel Facility, in parallel with The General Electric Company's light probe system. The results at all operating speeds were comparable. This report provides a brief description of the system and presents a summary of the experimental results

Quantitative Gene Action and Interrelationships of Protein Content With Some Metrical Traits of Oats

The objectives of this study were (a) to determine gene action, heritability and number of effective factors controlling protein content in oats, (b) to investigate the interrelationships of protein content with other agronomic characters, and (c) to evaluate the feasibility of utilizing A. sterilis germplasm in oat breeding projects. Four genetically distinct cultivars with protein content ranging from 15.7 to 26.6 percent were crossed in all possible combinations to make a complete set of diallel crosses. The data suggested additive gene action and partial dominance for protein content. Groat percentage and number of panicles showed overall partial dominance. Yield and days to heading indicated over-dominance, whereas height, plant weight and groat weight exhibited complete dominance. A. sterilis manifested dominance for early heading, low groat percentage and a large number of panicles. It exhibited recessiveness for yield, plant weight and groat weight. Narrow sense heritability for protein content varied from 41 to 83 percent while broad sense heritability ranged from 0 to 98 percent depending on genotype, environment and method used for computation. Genotype x environment interactions for protein content were significant. Frequency distribution for protein content in the F3 generation was reasonably symmetrical. Mean protein content was skewed toward the low protein content. F3 progeny from a cross involving two low protein parents had a lower average protein percentage than either parent. Some crosses had progeny with as high as 25 percent protein and yield above the mid-parent value were observed. Number of effective factors controlling protein content varied from 1 to 19, depending upon the method of determination and genetic diversity of the parents. Protein content exhibited negative correlations with yield, plant weight, height, number of spikelets, groat percentage, leaf length, leaf width and days to heading. A positive correlation of protein content was observed with awns, which is a A. sterilis characteristic. On the basis of standard partial regression coefficients, number of spikelets and yield were the most influential variables to predict protein content in the F1 and F3 generations, respectively. To predict yield, plant weight and number of spikelets were the best factors. There was a constancy of generation means for protein content in the F1, F2 and F3 generations. General combining ability, specific combining ability and reciprocal effects were significant in the F1 generation for protein content. Based upon this study, it can be concluded that the high protein content of A. sterilis can be combined with agronomic traits of A. sativa. This might be achieved by selecting from large populations of segregating material followed by backcrossing to A. sativa to recover better agronomic traits

Subterranean clover yield and nutrient content as influenced by soil molybdenum status

During the Spring of 1969, 47 surface soil samples (0 to 15 cm) as well as foliage samples of subterranean clover were collected from 32 selected western Oregon pastures, in an effort to determine their molybdenum status and to evaluate the use of anion exchange resin method as a means of assaying available molybdenum. The five most acid soils were limed to 80 percent base saturation. Greenhouse experiments were established during September, 1969, to evaluate the effect of molybdenum fertilization of subterranean clover yield and nutrient content. Highly significant yield and total nitrogen responses of subterranean clover were obtained following molybdenum fertilization. Greatest percent yield as well as percent total nitrogen responses to applied molybdate occurred at the lower soil anion exchangeable molybdenum concentrations. Statistically significant correlation coefficients were obtained between anion exchangeable soil molybdenum and percent yield response to applied molybdate in the greenhouse studies (r = -0. 743); anion exchangeable soil molybdenum and plant nitrogen concentrations in field subterranean clover samples (r = 0.875); anion exchangeable soil molybdenum and percent total nitrogen response to applied molybdate in the greenhouse studies (r = -0. 560); anion exchangeable soil molybdenum and plant molybdenum concentrations in field clover samples (r = 0.861); anion exchangeable soil molybdenum and soil pH (r = 0.861)

Assessment of Variations in Sphenoid Sinus Pneumatization in South Indian Population

Introduction Morphometric study of sphenoid sinus shows various degrees of pneumatization. Knowledge of such variability is extremely important to guide the surgeon in predicting what type of surgical approach will be safer for the pathologies involving skull base region. Considering recent advances in trans-nasal trans-sphenoidal endoscopic interventions and improved visualization, it has become imperative to become familiar with the anatomical variations which are likely to be encountered during surgical procedures.   Materials and Methods A retrospective study was conducted on the basis of CT scan records of 120 patients to evaluate variability in pneumatization of sphenoid bone and its extensions in South Indian population.   Results The study revealed the prevalence of conchal, pre-sellar, incomplete sellar and complete sellar types of sphenoid pneumatization in 02%, 08%, 28% and 62% cases respectively. Posterior or clival extension was the commonest type seen in 80% cases which included sub-dorsal (50%), dorsal(15%) and occipital(15%) types of clival variants. In lateral extensions, pterygoid sub-type was observed in 37% of patients whereas lesser wing, greater wing and full lateral sub-types were present in 20%, 14% and 09% cases respectively. Various combinations of lateral sub-types were seen in 15% of study population. Conclusion In our study higher percentage of pneumatization of sphenoid sinus and its extensions was observed when compared to Egyptian and Chinese populations. High prevalence in South Indian population also provides an additional armament in the hands of surgeon to reach the otherwise unreachable lesions involving middle and posterior cranial fossae through trans-sphenoidal approach

Human Mind’s Transformation is Crucial for Self Realization

The human mind is central to comprehend and manoeuvre the natural world. Though it is the crown expression of Nature in the mortal world, it is inherently inconsistent. It is often captivated by many animalistic habits. One of the animalistic habits of mind is its fickleness. Sikh theology emphasizes that one must learn how to control and transform one’s mind to come out of this condition. An individual can do so by diverting his/her mind from its feral inclinations and turning it to the mind’s innate longing for spiritual enlightenment. Sikh doctrines assert that the contemplation on God (imbibing love of God in one’s life) helps restrain the mind and attain self-realization and everlasting equipoise

DMPA provision in PSS clinics in Uttar Pradesh: Costs and prices

The injectable contraceptive DMPA was introduced in the private sector in India in 1993, contingent on completion of a post-marketing surveillance study of users. The commercial price of a dose of DMPA is about Rs. 150-180, exclusive of the fees of the medical provider. This price puts it beyond the reach of most Parivar Seva Sanstha (PSS) clients in need of safe and effective family planning (FP) services in Uttar Pradesh. Since April 1996, an experiment has been underway with three PSS clinics in Uttar Pradesh to study the effect of price on demand for DMPA. The study seeks to better understand the issues of service delivery, client profile and the price at which the service can be offered in a sustainable way. Since April 1996, PSS has charged clients selecting DMPA Rs. 50 in Agra, Rs. 100 in Lucknow, and the product is offered free in Varanasi. All other PSS clinics in India offer the product at Rs. 50. This cost analysis has two main objectives: to estimate the cost of providing DMPA services at three clinics in Uttar Pradesh and to analyze the price at which DMPA services can be sustainably offered given the cost structure at each clinic

Resistance gene cloning from a wild crop relative by sequence capture and association genetics

Disease resistance (R) genes from wild relatives could be used to engineer broad-spectrum resistance in domesticated crops. We combined association genetics with R gene enrichment sequencing (AgRenSeq) to exploit pan-genome variation in wild diploid wheat and rapidly clone four stem rust resistance genes. AgRenSeq enables R gene cloning in any crop that has a diverse germplasm panel
