An initial survey of the diversity of early lignotuber development in Eucalyptus and an analytical study of the anatomy of young lignotubers and the seedling stem are presented. Studies of the early stages of the morphological development of the lignotuber in 13 species, representative of five taxonomic groups, resulted in the recognition of four modes of lignotuber initiation. The importance to lignotuber formation of the presence of a suite of accessory buds, adaxial to the axillary bud, is emphasized but lignotuber initiation is not in all cases associated with these buds. Lignotuber buds are derived by branching from existing buds, ultimately from the accessory buds of the node. Following its initiation, the possibilities of later morphological development of the lignotuber are discussed. Lignotuber growth may dominate over stem growth and the lignotubers at a node may then fuse laterally to encircle the stem. Stem growth, on the other hand, may dominate over lignotuber growth and the lignotuber then appears to regress. The consequences for the growth habit of the plant of these alternative pathways of development are outlined. The wood of young lignotubers (and that of the swollen hypocotyl) is shown to be different in composition and in the sizes of its elements from that of seedling stem wood; these differences owe their origin to differences in the nature and performance of the cambia of the lignotuber and stem. In lateral fusion of the lignotubers at a node, and their upward and downwards extension over the stem, e.g. over the hypocotyl, stem cambial initials are either progressively lost or, more likely, converted to lignotuber-type initials. The possibility of the reverse process occumng in stem dominance is discussed.

This paper presents the results of an analytical study of turbomachinery requirements and configurations for Brayton-cycle space-power systems. Basic turbomachinery requirements are defined and typical effects of such system design parameters as power, temperature, pressure and working fluid on turbomachinery geometry and performance are explored. Typical turbomachinery configurations are then presented for systems with power outputs of 10, 100 and 1000 kw.

Gyroscopic Effects

An analytical study of a vibrating bandsaw blade is presented. The blade is modeled as a plate translating over simply-supporting guides. Gyroscopic effects due to the blade’s axial motion as well as in-plane forces resulting from tensioning and the influence of the cutting force are included in the model. The latter is modeled as a nonconservative follower force on the cutting edge of the blade and shown to be destabilizing. A state-space model is developed which includes the effects of time-varying cutting forces and exogenous disturbances. Feedback control via a collocated force actuator/rate sensor is introduced and recent advances in robust control theory are used develop controllers which achieve robust stability and performance with respect to the time-varying model.

Performance and efficiency of co-operative banks are the key elements of a country’s financial system at primary level. The co-operative societies in India, in fact, are playing multifunctional role in both rural as well as urban areas. This paper explores the financial growth and performance of Kangra Central Co-operative bank in Himachal Pradesh, which is the largest co-operative banks in the state. The main objective of the study is to analyse the performance and present financial position of the Kangra Central Co-operative bank in Himachal Pradesh with regard to its branches, ATMs, customers etc, using secondary data. The study is set out to apply growth rate for evaluate performance of bank through different variables like share capital, shareholder funds, deposits, assets, outstanding advances, borrowing, profit and profitability and check the management efficiency of the bank through operating ratio. This analytical study of KCCB demonstrates that there are significant differences between different study time periods on the performance of the banks in terms of share capital, deposits, borrowing and profitability, market coverage, outstanding advances, profits, shareholder funds and management quality.

The effect of innovation on performance of Small and Medium Industries (SMIs) draws a great ofattention from researchers and practitioners to study further. Based on empirical findings, it is foundout that the correlation between innovation and performance is dependent on context, that is theinnovation does not affect the performance of a company or indicated negative implication betweeninnovation and performance. Meanwhile, other researches reported positive effects of innovation andperformance. The review of researches on the correlation between innovation and SMIs performanceshows contradictory results.The meta-analytical study is aimed at investigating further thecorrelation between innovation and performance on SMI based on researches published between 2004and 2013 in 5 continents (Australia, Asia, Europe, Africa and America). The independent variablewas innovation and the dependent variable was performance, while the moderators variable consistedof the year of the research and the location of survei. The result of the meta-analytical study on thecorrelation between innovation and performance indicated a positive correlation with mean 0.459and the standard deviation 0.168 on 95% confidence interval.

Background: Today, the use of dental radiography equipment in dental centers has increased due to its high application in the diagnosis of dental diseases. As a result, concerns are increasing regarding repeated exposure to this low dose level of radiation. Therefore, the knowledge and practice of dentists about radiation protection are essential for themselves and the patients. This study aimed to assess the knowledge and practice of dentists about radiation protection. Materials and Methods: This cross-sectional study was performed based on a questionnaire in several cities of Iran. The first part of the questionnaire included such information as gender, years of work experience, and participation in radiation protection workshops. The second, third, and fourth sections consisted of questions on radiobiology, radiation protection, and performance, respectively. Results: In this study, 94 dentists participated, and the mean scores of dentists (out of 5 points) for radiobiology knowledge, radiation protection knowledge, and performance were obtained at 2.66±1.1, 2.80±1.01, and 2.87±1.37, respectively. The results of Pearson analysis showed that general knowledge had a significant relationship with performance (P=0.014). There was also a significant relationship between the history of participation in radiation protection workshops and performance (P=0.01). Conclusion: It was found that more knowledge about the effects of ionizing radiation on the body and more awareness of the principles of radiation protection would help dentists to better observe the practical principles of radiation protection. Also, participating in radiation protection workshops could increase dentists' knowledge, and therefore, improve their performance.
