geospatial data [ 2 ]. The management and analysis of GIS data are traditionally done using Relational DataBase Management Systems (RDBMS) due to their strong data consistency, transactional support, and Atomicity, Consistency, Isolation, and Durability (ACID

Change is a constant truth in a modern society; an organization no longer faces environments as stable as they used to be. In the face of the stronger market competition, an organization should deliberately consider and make proper responses in the operation in order to cope with the changeable environment and sustain the organizational life. When facing the changes in markets, an organization not only needs to constantly consider the changes in external environments, but also has to face the boycott or resistance of internal members to the organizational change. The effects of Human Resource Management System on Organizational Commitment therefore become critical.We have taken the Hsinchu Science Park as the research sample, in which the employees and supervisors of manufacturers have been randomly sampled. A total of 600 copies of questionnaires were e-mailed and 276 valid copies were retrieved, with the retrieval rate of 46%. The research results conclude significant correlations between 1. Human Resource Management System and Organizational Commitment, 2. Organizational Commitment and Business Performance, and 3. Human Resource Management System and Business Performance.

Diverting household waste from landfill had become a must for EU member states. The mechanical and biological treatment of household wastes is one of the key method to reach this goal. The object of the mechanical handling is to separate the recyclable fraction and transform the non-recyclable part into Refuse Derived Fuel (RDF) for energetic use and produce fraction for biological treatment. Our challenge to identify the ideal technology for RDF production for the North-Balaton Regional Waste Management System, by studying the existing technologies, and emerging needs from the growing market especially for Cement Industry and pyrolitic technologies.

The Szentágothai János Research Center in Pécs brings computer based building physics simulations to reality closer than ever. This high class building ads ground to several medical research programs and lectures, but it also gives a rare opportunity to improve computer simulations with its’ Building Management System (BMS from now on). The system does not only allow the complex building services system to be remotely controlled from a single computer, but also gathers important data related to the buildings’ physical performance, for example: room temperatures; air flow rates; geothermal pipe performance; and energy consumption of heat pumps. By comparing the results of a zone based building physics simulation model of the building, enhancement of the precision of the simulations and optimization of the actual buildings energy consumption can be done, by trying out different maintenance strategies.The first step is to build the computer model to be as precise as possible. In the zone based physical model, energy flows between zones, but the zones themselves often lack precise physical attributes, like energy loss through heat bridges. In this paper we will show how 2D finite element heat transfer simulations improve, zone base whole building simulations.

The effect of free-range versus cage management system on corticosterone transfer into the eggs was studied in laying hens. Hungarian Yellow laying hens (age: 21 weeks, body weight: 2.0 ± 0.5 kg) were divided into two groups in the spring: Group I, free-range keeping (n = 15 layers, density: ≯ 0.5 bird/m2) in outdoor runs, with continuous access to a commercial layer feed; Group II, hens kept in battery cages (n = 17 layers, density: 2 birds/m2, natural light, continuous access to feed and water). Eggs were collected after a one-week adaptation period on days 2, 7 and 16. Corticosterone (CST) was extracted from homogenised egg samples using an ASE-200 Accelerated Solvent Extractor and then assayed by liquid chromatography linked with tandem mass spectrometry (LC-MS/MS) [Thermo Quest Surveyor high-performance liquid chromatography (HPLC) interfaced via Atmospheric Pressure Chemical Ionisation (APCI) ion source to Finnigan/Thermo Quest LCQ Deca MS/MS] using dexamethasone as internal standard with positive APCI ionisation. CST concentrations of whole eggs laid by free-range hens on days 2, 7 and 16 were 0.370 ± 0.218, 0.259 ± 0.066 and 0.915 ± 0.745 ng·g-1, respectively, while those of eggs laid by caged hens were 0.206 ± 0.157, 0.223 ± 0.165 and 0.184 ± 0.110 ng·g-1 at the above sampling times. It is concluded that in free-range laying hens the sharp changes of environmental weather conditions significantly increased the corticosterone content of eggs, while the environmentally controlled and closed battery cage management technology resulted in relatively uniform corticosterone concentrations in the whole eggs.

The retention of pendimethalin by humic acids (HAs) from different farm wastes and from soils in various management systems was studied at 20 and 40°C. The magnitude of pendimethalin retained varied from 19.50–71.00 and 20.50–80.00 μM g −1 at 20°C on HAs from farm wastes and soils, respectively, which decreased with a rise in temperature. Pendimethalin retention followed the order: Soil HAs > Farm waste HAs. The highly significant values of R 2 suggested the excellent fitness of the Freundlich (0.965**–0.996**) and Langmuir (0.943**–0.986**) isotherms for pendimethalin retention. The values of the ‘k’ and ‘n’ retention parameters of the Freundlich isotherm and the ‘K’ and ‘b’ parameters of the Langmuir equation confirmed the relatively higher capacity of soil HAs to retain pendimethalin.

Abstract  

Except the nuclear fuel reprocessing and nuclear materials safeguards, at present there are two areas of an increased responsibility of nuclear scientists for their results: radioecology and human medicaments. At both of them, quality and trustfulness of results is of great importance for their end-users and may have serious economical and legal consequences. The trends of implementation of good laboratory and manufacturing practices under umbrella of international quality management standards like ISO 17025:2005 and ISO 9001:2000 in radiochemical and radiopharmaceutical laboratories are discussed as expanding to “good scientific practice”. The case studies of the Comenius University laboratory LARCHA authorized for radiochemical analysis, and the company BIONT producing medical radionuclides and PET radiopharmaceuticals are used as the examples.

Changes in the chemical contents of the kernels of maize hybrids were analysed in three consecutive years (one dry, one arid and one wet) in samples originating from irrigation and fertilisation experiments. The results indicated that while irrigation and wet years had a protein-decreasing effect, the water supply did not influence the starch and oil contents. Under the influence of fertilization, the calcium and zinc contents of maize kernels decreased to varying degrees depending on the hybrid, while the sulphur contents changed parallel to the protein contents. Based on these data and on the use of more modern measuring equipment, tables giving recommendations for chemical contents should be revised.

The topic of this paper is to examine the production and power-plant utilization of biomass and waste-derived combustibles with the aim of recovering energy and heat. During biomass production the simultaneous composting of municipal solid waste and sewage sludge can provide the nutrient supply of the energy forests that are planted as biomass raw material. In the controlled decomposition process (fast composting) gas development and emission can be controlled, the amount of waste that is permanently deposited can be minimized and its harm to the environment can be reduced significantly.
