A simulation of the instrument pointing system for the Astro-1 mission

NASA has recently completed a shuttle-borne stellar ultraviolet astronomy mission known as Astro-1. A three axis instrument pointing system (IPS) was employed to accurately point the science instruments. In order to analyze the pointing control system and verify pointing performance, a simulation of the IPS was developed using the multibody dynamics software TREETOPS. The TREETOPS IPS simulation is capable of accurately modeling the multibody IPS system undergoing large angle, nonlinear motion. The simulation is documented and example cases are presented demonstrating disturbance rejection, fine pointing operations, and multiple target pointing and slewing of the IPS

Comparative Studies of Canon Law

To sum up, it should be noted that comparative studies of canon law can be carried out in various directions, starting from families of laws and ending with the theory of philosophy and practice. Canon law practice itself recognizes the need for such studies although their purpose is different from that of typical comparative studies. Identification of canon law as a system of law is crucial to canon law practitioners. It should be achieved by searching for specific elements in secular legal systems. Comparative studies of canon law can be divided into external and internal studies. The first compare canon law either with secular legal orders or with other systems of confessional law. Internal comparative studies focus on internal comparative analyses of canon law. They can also be carried out with reference to the law of the Latin Church and the Eastern Churches and with reference to particular law and the internal law of institutes of consecrated life and societies of apostolic life

Regionalisation of tasks related to environmental protection

This paper aims to analyse the criteria regarding the distribution of tasks related to environmental protection oriented at regionalisation of such tasks. Further, it provides an assessment of regionalisation along with the postulates de lege ferenda (i.e. the law as it should stand). Regionalisation of tasks related to environmental protection is very significant from the point of view of performance of tasks related to environmental protection. Regionalisation of such tasks should take into account the following aspects – area of impact and area of protection, cost of protection manifested in ensuring funds to finance such protection, the requirement of specialist knowledge and, finally, familiarity with local conditions. As a matter of fact, regionalisation of such tasks should be a compilation of all those criteria in total. It is not easy to establish the applicability of such criteria and weigh the significance of each of them in a specific situation. It is difficult to expect such an effect from the lawmaker. However, it does not mean that it should not make conscious reference to such criteria and apply them to the optimum extent possible

Responding to Difference: Challenges for Contemporary Spiritual Directors

The global village of interdependence and diversity is evident every day. Whether it is the profound effects of the economic crisis, the increasingly multicultural and interreligious character of cities and neighborhoods, or the voices of racial and ethnic minorities in every aspect of life, we are all challenged to meet and embrace diversity. Spiritual directors are not exempt from these experiences since they accompany those diverse in culture, religion, gender, race and ethnic background, sexual identity, economic class, and age cohort

Państwowe Gospodarstwo Wodne Wody Polskie

On 20 July 2017 the Water Law Act was adopted[1]. This act introduced a number of innovative solutions that were completely new to the Polish legislative system. A complete novelty is, for instance, solutions regarding payment for water services or the implementation of certain solutions in the area of water protection and management. Other innovative solutions refer to the entity named Państwowe Gospodarstwo Wodne Wody Polskie (State Water Holding – Polish Waters). The legislator called it Wody Polskie (Polish Waters) for short.This article will present issues concerning that entity. It will cover the legal status of the entity, its tasks, powers and responsibilities, as well as structure.[1] Journal of Laws of 2017 item 1566, with further amendments

Act on the Protection of Animals Used for Scientific or Educational Purposes - legal regulation review

On 15 January 2015 the Act on the Protection of Animals Used for Scientific or Educational Purposes [1] was adopted in Poland. This act implements Directive 2010/63/EU of the European Parliament and the Council of 22 September 2010 on the protection of animals used for scientific purposes [2]. The Act on the Protection of Animals Used for Scientific or Educational Purposes is not the first legislative act governing the presumption of acceptability of using animals for scientific and educational purposes. The first legislative act in the system of Polish law regulating the above-mentioned issues was the Act of 21 January 2005 on Experiments on Animals [3]. However, it must be emphasized that the Act on the Protection of Animals Used for Scientific and Educational Purposes is not the only one legislative act regulating animal protection issues. Apart from the said Act there is the Act of 21 August 1997 on Animal Protection [4] and the Act of 11 March 2004 on the Protection of Animal Health and Control of Infectious Diseases of Animals [5]. Thus, in the Polish legal system animal protection is a very elaborate issue and is split concurrently between three underlying legislative acts. This article will, on one hand, attempt to evaluate the implementation of directive 2010/63/EU, and on the other, establish how the provisions of this act correspond to other legislative acts related to the protection of animals.

J-PET Framework: Software platform for PET tomography data reconstruction and analysis

J-PET Framework is an open-source software platform for data analysis, written in C++ and based on the ROOT package. It provides a common environment for implementation of reconstruction, calibration and filtering procedures, as well as for user-level analyses of Positron Emission Tomography data. The library contains a set of building blocks that can be combined by users with even little programming experience, into chains of processing tasks through a convenient, simple and well-documented API. The generic input-output interface allows processing the data from various sources: low-level data from the tomography acquisition system or from diagnostic setups such as digital oscilloscopes, as well as high-level tomography structures e.g. sinograms or a list of lines-of-response. Moreover, the environment can be interfaced with Monte Carlo simulation packages such as GEANT and GATE, which are commonly used in the medical scientific community.Comment: 14 pages, 5 figure
