Genetic response to index selection for the improvement of egg production efficiency in layer-type chickens

Recording individual feed consumption in layer-type chickens is costly. For this reason, feed record information in most commercial breeding programs is omitted. The present study focuses on the evaluation of feed records to improve egg production efficiency in two populations of Leghorns. From four generations of index selection based on body weight, egg mass and feed consumption information, sexual maturity was delayed, egg size and daily egg mass output increased and feed efficiency (egg mass/feed consumption) improved. On the other hand, selection on an index containing information only on body weight and egg mass, increased body weight, egg weight, daily egg mass and feed consumption, but it failed to improve feed efficiency. The preliminary results, therefore, indicate that feed record information aids in improving the efficiency of feed utilization;The selection responses obtained in two different populations of Leghorns were frequently inconsistent for several traits. This may have been due to an incorrect choice of the economic value constant for body weight in the selection indexes used in the two initial generations of selection. A contributing factor might have been a poor choice of parameter estimates taken from the literature which were needed to solve the index normal equations. It is concluded that to establish superiority of an index containing feed record information, additional generations of the selection experiment would be required. Data of the latest generations available might then be used to obtain better estimates of parameters needed to solve the index equations

Study on Genetic Variability, Heritability, Genetic Advance and Correlation among different characters in tomato (Solanum lycopersicum L.)

The present investigation entitled “Studies on genetic variability in tomato (Solanum lycopersicum L.)” was carried out at the UCOA, vegetable research farm, Guru Kashi University, Talwandi Sabo, Bathinda during rabi 2015-16 to evaluate tomato genotypes. The experiment was laid out in CRD with three replications. Total 20 genotypes including check cultivar were evaluated for horticultural Traits contributing yield and quality (suitable for processing) .There is a wide variability in different genotypes in tomato. Traits i.e. Number of primary branches per plant, Days to first fruit harvest, Plant height (cm),number of fruits per cluster, number fruits per plant, average fruit weight (gm), equatorial diameter of fruit (cm), polar diameter of fruit (cm), number of locules per fruit, pericarp thickness (mm), fruit pH, Fruit TSS (0brix), days to last fruit harvest and average yield per plant (kg) were studied during the investigation Analysis of variance showed significant differences among genotypes for all the characters under study during the investigation. High Phenotypic and Genotypic coefficient of variation were detected for characters like number of fruits per plant, number of locules per fruit, pericarp thickness and average yield per plant. High heritability coupled with genetic gain were recorded for number of fruits per plant, average fruit weight, number of locules per fruit and average yield per plant. Therefore these characters also show some scope for improvement through selection. A highly significant and positive phenotypic and genotypic correlation were found in number of fruits per cluster, plant height, number of fruits per plant and average fruit weight

Recent trends in operation modal analysis techniques and its application on a steel truss bridge

Aging of infrastructure causes many problems with great consequences, essentially economical. Operation modal analysis (OMA) is one of the most crucial techniques used for dynamic analysis of civil engineering structures (e.g. bridges, dams or tunnels). OMA uses various time and frequency domain methods to obtain the modal parameters. The analysis of OMA techniques can be used to detect, locate and quantify the damage in a structure. The major challenge for damage detection using OMA is the analysis of a large amount of noisy data collected from sensors. New signal processing techniques and artificial intelligence can play an important role in future research in the area. In this article, we present and discuss recent developments in OMA techniques and also give a concrete example on a steel truss bridge, where the most popular OMA techniques have been implemented and applied

A note on contributions concerning nonseparable spaces with respect to signal processing within Bayesian frameworks

In this paper, we discuss the study of some signal processing problems within Bayesian frameworks and semigroups theory, in the case where the Banach space under consideration may be nonseparable. For applications, the suggested approach may be of interest in situations where approximation in the norm of the space is not possible. We describe the idea for the case of the abstract Cauchy problem for the evolution equation and provide more detailed example of the diffusion equation with the initial data in the nonseparable Morrey space

In vitro evaluation of glass fiber post

Statement of problem: Techniques and recommendations for the restoration of endodontically treated teeth have changed from the use of custom cast metal post and core system to glass fiber-reinforced (GFRC) post and composite core system. Has this latest prefabricated glass fiber reinforced post and composite core system increased the fracture resistance of teeth and reduced the incidence of unrestorable root fractures. Purpose: The purpose of this study was to evaluate the incidence of root fracture and mode of failure of endodontically treated teeth restored with two different post and core systems. Material and methods: Forty maxillary central incisors were randomly divided into two groups. (n=20). All teeth received endodontic treatment. First group was restored with custom cast post and core system. Second group was restored with glass fiber post and composite core system. In Both the groups posts were cemented with adhesive resin cement. Compressive load was applied at an angle of 130 to the long axis of teeth at a cross head speed of 1 mm/min until fracture occurred. Data were analyzed with student 't' test P<.001. Results: The mean value for fracture resistance was (331.4025) N in Group -I Custom cast Ni-Cr post and core and (237.0625) N in Group -II Glass fiber reinforced post and composite core system. Students 't' test shows the significant difference in fracture resistance of two groups. Conclusion: This study showed that the incidence of root fracture was significantly higher in custom cast Ni-Cr post and core system than glass fiber post and composite core system. A more favourable mode of failure was observed in teeth restored with Group II glass fiber post system

東南アジアにおける感染症の予防と制御に対する効果的な公衆衛生学的対応のための新たな診断ツールの開発

Diagnostic capacities must be built and sustained in Southeast Asian countries to detect and to anticipate the emergence of infectious diseases. This will allow effective and timely public health action to be implemented for the prevention and control of infectious diseases. The objectives of this thesis were to develop newer diagnostics tools for the detection of infectious diseases which can be used to generate infectious disease information that will be crucial in the implementation of effective public health action for the prevention and control of infectious diseases in Southeast Asia. In order to achieve these objectives, investigations of the nature of infectious diseases in Southeast Asia were carried out. Specifically, a new method for the rapid and total characterization of viruses was developed. Serologic diagnostic test for an emerging virus affecting Southeast Asia was developed and used in a population survey in Southeast Asia. To support these investigations, new diagnostic tools were developed. These new tools with microstructures reduced the total time and volume of samples needed for the diagnosis of infectious diseases. In addition, a portable disease diagnostic system for rural and onsite testing was utilized to generate infectious disease information. The newly developed method for the characterization of virus was applied in the investigation of a new virus affecting Southeast Asia, namely Pteropine orthoreovirus (PRV). This new method reduced the total time and effort required to complete the investigation of PRV and showed crucial information on the existence of PRV in Southeast Asia. Although human infections with PRV are mild, the use of the newly developed serologic test showed that humans in Southeast Asia are at risk of infection with PRV. These experimental findings also showed the first evidence of human infection with PRV in Vietnam. The newer diagnostic tools developed were used in the detection of infectious diseases in Southeast Asia and showed an increased sensitivity with the potential to reduce time and volumes compared to the standard methods. These are crucial consideration for the uptake of diagnostic tools in resource-limited settings like Southeast Asia. This thesis is composed of five chapters. The introduction and main achievements of this study are summarized below. Chapter 1 introduces the background of infectious diseases in Southeast Asia and the current methods to detect them. The limitations in the present methods are mentioned and approaches in overcoming them are indicated. In the overall context of infectious disease detection in guiding public health action in Southeast Asia, the motivation and objectives of this study are stated. Chapter 2 investigates the nature of infectious diseases in Southeast Asia. A new method to characterize PRV was developed and used in investigating the nature of PRV infection. This method reduced the total time required to complete the investigation from at least 6 months to less than 1 week. Serologic methods were also developed that showed that human infections with PRV are more common than previously known. These assays showed evidence of human infections with PRV in Vietnam. These assays can be used to detect a change in nature of PRV from mild to potentially fatal cases and to investigate the geographic distribution of this new virus. Chapter 3 investigates the development of new tools for the diagnosis of infectious diseases in Southeast Asia. Tools with microstructures to increase the surface area and reduce the volume required were designed, developed and validated feasibly and rapidly. These tools showed a sensitivity of at least 4-fold higher than the standard method. These tools also showed a potential to reduce the time and volume up to 90% less than the standard method. Chapter 4 investigates the implementation of these methods in building sustainable public health actions in Southeast Asia for the prevention and control of infectious diseases. These tools were used in field studies and showed results equivalent to the standard methods with reduced time and volumes needed by at least 6.5-folds less. Also, public health education materials were developed in selected national languages for use during disease outbreaks. Chapter 5 summarizes the whole thesis. The contributions of this study in sustaining public health action are presented. Future works to build these detection capacities for infectious diseases in achieving national, regional and global public health security in Southeast Asia are recommended.首都大学東京, 2015-09-30, 博士（工学）首都大学東
