Management Practices for Lentil as Relay Crop in the Rice Based Cropping System

The field experiment was conducted at Pulses Research Centre of Bangladesh Agricultural Institute （BARI）, Ishurdi, Pabna, Bangladesh during rabi season of 2009 to find out the suitable management package for better plant establishment and higher yield of lentil under relay cropping. The experiment was based on three genotypes--Rajbari local, X95S-167（4） and X95S-136; two types of rice straw height--I 0 cm and 30 cm, three seed rates （kg/ha）--e.g., 30, 50 and 60, and three levels of fertilizer--control, 30-60-20 kg/ha of N-P2Os-K20 and 30-60-30 kg/ha of N-P2Os-KzO. The experiment was laid out in a split-split-split-plot design with three replications. Genotype was placed in the main-plot, rice straw height was in the sub-plot, seed rate was in the sub-sub-plot and fertilizer level was in the sub-sub-sub-plot. From this study, it was observed that lentil genotype X95S-136X planted with a rice straw height under 30 cm, at a seed rate of 50 kg/ha, and with a fertilizer level at 30-60-30 kg/ha of N-P2Os-K20 produced the highest lentil seed yield of 2,070 kg/ha and the lowest seed yield （550 kg/ha ） was obtained from genotype Rajbari local, planted with a rice straw height under 10 cm, at a seed rate of 30 kg/ha and no fertilizer. Similar result regarding seed and straw yield was also found in the farmer＇s field. The accession X95S-136 along with improved production technologies produced the highest grain and straw yield, and net return but the lowest grain and straw yield as well as net return were obtained by Rajbari local in the demonstration field. It was also identified that, by the inclusion of lentil in the transplanted monsoon rice field, lands could be brought under lentil cultivation to enhance lentil production, provide human nutrition and also to ensure soil health improvement for sustainable production system.

The decision-making dimension of the systems approach to management

Theoretically, a system is anything that is made up of various parts. Theses parts are known as subsystems. At every point in time, these parts should work in harmony so that objectives could be achieved successfully. A system could be inanimate or animate item. Examples of inanimate systems include vehicles, households, computer and institution. Examples of animate systems are human being, animal and insect. Both inanimate and animate systems are made up of various subsystems. Such subsystems are required to co-operate, collaborate and work together so that set objectives could be achieved successfully. From practical managerial point of view, business organizations are equally systems that are made up of subsystems which may take the form of departments, sections and/or units. It is supposed to be collaborations among the managers and other members in these departments, sections and/or units so that organizational objectives could be achieved. All the managers in various departments, sections and/or units are required to work together as a team to make the system coherent and closely-knit to make disintegration impossible. Closely related to the systems approach to management is managerial decision-making. Decision-making is a very important function of every manager＇s job. The success and failure stories of many organizations are the result of the quality of decisions made. Many organizations have survived turbulent conditions. Others have also collapsed in spite of favourable conditions. These varying conditions are the result of the quality of decisions made by managers at positions of authority and responsibility. Therefore the systems approach to management enjoins top managers in particular to be very circumspect and cautious in certain decision-making activities. This is because, the quality of decision a manager makes can go a long way to determine the success or failure story of an organization as exemplified in the case study in this paper.

A two-tier location management mechanism for IMS

This paper proposed a two-tier location management mechanism （TTLM） by improving the current registration mechanism （CR） in IP Multimedia Subsystem （IMS）. The TTLM includes the visited network registration and the home network registration, in which the visited network registration is responsible for re-registration in IMS. When subscriber roams, the location information of home network will be updated by the visited network based on the change of user equipment （UE）＇ s IP address. Thereibre the TTLM can reduce the times of IMS registration signaling. Using the proposed analytical model, the performance of the CR and the proposed TTLM were investigated. After the performance analysis of CR and TTLM by using proposed analytical model, the cost of CR in IMS could significantly be reduced theoretically and also was proven by simulation experiments.

Modeling of Raw Materials Management on the Example of Textile Production Company

The aim of this paper is to propose a discussion about inventory control and to present a new method for testing the control process in terms of uncertainty. The subject matter is modelling for optimal control that ultimately provides the basic parameters for the level of safety stock and the cycle of deliveries. An optimisation criterion is a function minimising the total costs of storage and production coming to a halt because of depleted stock of inputs. Considering the results of the study, it is found that appropriate management process of textile companies requires determining raw materials stocks and its costs very precisely. The stream management process in the enterprise includes an element of fluctuations in demand. This is the source of ＂a conflict＂ that appears in two sub-systems： storage and production. At the same time, a systemic approach to the optimal coordination of supply/production calls for effective management of the whole system. Implementation of modem information technologies is one of the factors that support the effective control.

VSS BASED SESSION SETUP MECHANISM IN IMS

This paper proposes a novel session setup mechanism in IMS(IP Multimedia Subsystem) by introducing the functional entity termed VSS(Visitor Subscriber Server) which is used to provide registration and location management.The new mechanism aims at improving session setup procedure by a betterment of location management in IMS.Through the use of two-tier subscriber information database constituted by the HSS(Home Subscriber Server) and the VSS, the new mechanism seperates the registration procedure and location management from the S-CSCF(Serving-Call'Session Control Function), and makes them be handled by the VSS.At the same time, the new mechanism updates the signaling procedure of registration and session setup.With VSS based location management, the cost of registeration and session setup procedure as well as the delay of session setup procedure become lower.The cost and delay functions of the new session setup mechanism as well as the cost function of new registeration are deduced.Then, simulations and analysis verify that the performance of this new mechanism gets the benefit in cost and time.

Controllable Optical Solitons in Optical Fiber System with Distributed Coefficients

We present how to control the dynamics of optical solitons in optical fibers under nonlinearity and dispersion management, together with the fiber loss or gain. We obtain a family of exact solutions for the nonlinear Schrfidinger equation, which describes the propagation of optical pulses in optical fibers, and investigate the dynamical features of solitons by analyzing the exact analytical solutions in different physical situations. The results show that under the appropriate condition, not only the group velocity dispersion and the nonlinearity, but also the loss/gain can be used to manipulate the light pulse.

Information System for Administrative Services of Educational Process

The goal of this paper is to analyze and propose a reconstruction of functional possibilities and database requirements of a Web based Educational Information system. For the research the Information system of the Technology School ＂electronic Systems＂ （TUES） associated with the Technical University of Sofia is on focus. The modules for admission of students, specialty classification, and graduation of students, management of the student＇s work in computer classrooms and lecturers＇ data management have been analyzed, developed and implemented. The additionally developed modules concern mainly the management of educational process and do not affect the e-learning or the official part modules. That led to the idea that the functionality for managing educational process has to be organized in a separate module defined as module for administrative services of educational process. Such restructuring of the system will bring flexibility in further growth of the system--for example students＇ admission or selection for different purposes.

Intramedullary devices in the management of Judet III and IV paediatric radial neck fractures

Purpose： The aim of this study is to discuss the results of different intramedullary devices used in the management of paediatric radial neck fractures and to suggest methods to avoid the pitfalls of the technique. Methods： Thirty patients with isolated Judet III and IV fractures were included in this prospective study. Judet I and II fractures and radial neck fractures associated with other injuries were excluded. The final results were graded using the Metaizeau functional scoring system and Oxford Elbow Score. Results： The functional result was good to excellent in 24 of 30 cases （80%）. The mean Oxford Elbow Score was 44.32. The mean follow-up was 40.11 months. The complications seen were radiocapitellar joint penetration - 6 cases at mean 4.87 weeks, redisplacement - 6, radial epiphyseal sclerosis - 5, and heterotopic ossification 1 case. Conclusion： lntramedullary K wires may result in radiocapitellar joint penetration. Titanium Elastic Nail System should not be used as purely fixation devices as they may not prevent redisplacement. Regular follow-up until at least 6 weeks is essential. Patients who have a Judet IV fracture and need open reduction should be given a guarded prognosis. The paper highlights the pitfalls of the technique and makes recommendations regarding the type of implant, follow-up and patient counselling in Judet IV fractures.
