The paper analyses technical equipment of the selected dairy farms. Data from questionnaires carried out in 96 farms in 2015 constituted a research material. Municipalities Lszewo-Borki in Mazowieckie Voivodeship were covered by the survey. A survey questionnaire, which consisted of two parts, was a research instrument. The first concerned general information on a farm and its owner, and the other consisted of eight questions on technical equipment used for breeding dairy cows. The research allowed to determine that farmers assessed the condition of their machinery park as average (50%) or good (40%). One out of ten farmers claimed that the used machinery park in a farm is in a bad condition. Majority of respondents have allotted from PLN 20 to 50 thousand for investments related to enhancement of a machinery park within the last 5 years. On the other hand, a considerable part of farms allotted up to PLN 20 thousand for development of a machinery park. The investigated group included also farms, which allotted more than PLN 500 thousand for development of a park.
The aim of the paper is to discuss the links between modern livestock production, including its techniques and concentration, with animal welfare requirements. Modern livestock production is related to modern facilities, precise livestock production, as well as intensive and high stocking density. At the same time, it requires providing the animals with minimal living conditions, i.e. the welfare set out in the relevant regulations. This in turn should guarantee a good quality of raw livestock materials and products.
The use and maintenance of technical systems throughout their lifecycle aims at achieving goals that allow for high values of productivity and availability characteristics of these systems. In the economic policy of each state or private organization or state institution, there is the right to determine the type of adequate maintenance system within the maintenance strategy adopted. Thus, the types of maintenance systems recognized in the technical domain are analyzed from the point of view of the two previously-mentioned features, productivity and availability, thus making the predictive maintenance system, derived from the preventively-planned one, advantageous for all organizations. It is obvious that the current trend is to spread this predictive maintenance system, according to which the interventions will be carried out before the malfunction occurs, depending on the periodically measured values of global pressure, flow, energy consumption, temperature, current, voltage, vibrations, etc.
"sound recording" can be
interpreted broadly, which means that under the term "sound recordings" need
not be understood only carriers of audio information that are directly reproduci-
ble by means of a technicalequipment intended for sound reproduction but even
such objects which are already technically outdated (e.g. musicboxes or auto-
matic musical instruments) or that are relatively new but specifi c or rare (e.g.
music roads). Th erefore in some case unclear or imprecise defi nition of "sound
recording" may lead to doubt whether a particular object ought to
Original experimental technical equipment for making samples in the form of permeable tubes of porous material, i.e. coiled wire. The article describes the construction of the equipment, the processes of forming and pressing the wire semi-product and methods of fixing the ends of the wire product.
The man-machine system consists of two subsystems fundamentally different, one representing the human factor and the other the technical equipment. The reliabilities of the two subsystems are treated with different methods, given their different nature. Consequently, linking them to use a single indicator of reliability is achieved with difficulty. This article introduces a new indicator of the system reliability indicating the overall reliability of the man-machine system and proposes a method for calculating this indicator.
The determination of how efficiently filtration systems used for the production of breathing air used in hyperbaric environments are operating is significant both from theoretical and practical points of view. The quality of breathing air and the breathing mixes based on air is crucial with regard to divers' safety. Paradoxically, a change in regulations regarding quality requirements for breathing mixes has imposed the necessity to verify both the technical equipment and laboratory procedures used in their production and verification. The following material, which is a continuation of previous publications, presents results of the conducted research along with the evaluation of effectiveness of the filtration systems used by the Polish Navy.
Nowadays, international and national events clearly point out the need for cooperation between different defense organizations in crisis and emergency situations (disaster events, migration issues, and other emergencies) for successful tasks. The fundamental basis of this cooperation is always the command and control activity supported by modern technical equipment that ensures the coordinated implementation of tasks. The key, human element of info-communication support is the preparation and training of the successful professionals. In this paper, the authors intend to present the importance of vocational training.
Each enterprise must worry about its technical equipment. There are many concepts and strategies to improve the management of the maintenance, e. g. TPM, RBI, LCC, CBM, RCM etc. However, the basis for each one of these systems should be the equipment categorization. The purpose of categorization is to classify equipments according to the type of risk associated with their main function. This allows to focus attention on the parameters and the criteria used to assign the degree of risk when the equipment fails and to determine the proper method of maintenance.
A basic requirement for a modern communications system is the protection of the communications services provided and of the information transmitted through them. This consists of a set of security measures and procedures organized in accordance with the legal provisions in force within each military structure, for the protection of the stored, processed and transmitted information through communications and informatics systems against threats and actions/inactions that may affect their confidentiality, integrity, availability and authenticity or may affect the operation of communications and informatics systems. In these circumstances, the development of communications equipment and the growing integration of the related technical equipment is accompanied by the emergence of numerous means and processes whereby unauthorized access to classified information may be achieved, both by direct interception of the traffic - especially the one transmitted by electromagnetic waves and the unintended (parasite) radiation of the communications and computing equipment. Therefore, a secure communications system within the modern battle space cannot be concieved without technical equipment needed to protect classified information, mainly based on automatic encryption and on appropriate organizational measures
