Opis:
The main purpose of this article is to demonstrate the possible continuity between early Palestinian cults reconstructed from anthropomorphic figurines and later beliefs. Figurines from the major archeological cultures including: Kebarian, Natufian or Yarmukian indicate a common ceremony of religious character, possibly connected with the cult of fertility. In this contexts particularly noteworthy is so-called „Ain Sakhiri Lovers” figurine which is unique and interpreted as showing a sexual intercourse. By presenting some of the types of early Palestinian anthropomorphic figurines, the author would like to discuss possible connections between earliest artifacts of probable religious meaning with documented religious systems.

Opis:
Great Mosque of Damascus was built between 705 and 715 by the Umayyad Caliph al-Walid I. However, the origins of this building dates to the distant past. At first it was a location of an ancient Aramaean temple dedicated to the god Hadad. With Hellenization the temple was dedicated to Zeus and in the first century BC the Romans transformation it into the Temple of Jupiter Damascenus. In 391 Emperor Theodosius converted the temple into Christian Cathedral of Saint John. Erection of the mosque by Caliph al-Walid I was under strong influence of earlier constructions. Meaning and consequences of such transitions, from the Roman temple (there is almost no data of the Aramaic building) through the Christian Cathedral to the Islamic mosque is an interesting process. Issue not only within the art and architecture, but what is more, in a religious aspect of the continuity of sacred space.

Opis:
The last few decades have been characterised by the rapid development of technology and various industries around the world, as well as increasing levels of urbanisation. The development of technology has resulted in the emergence of many inventions, vehicles and equipment. This has resulted in many unforeseen consequences generating threats to the environment in which humans’ function. One of these hazards is the noise emitted by vehicles. For this reason, environmental protection was created in response to threats to human existence (this work is to determine the level of noise resulting from traffic transportation in the city of Pila. In order to achieve the given objective in the city, sound values will be adopted and an acoustic map will be developed on their basis. A large amount of noise in the city of Pila is caused by road transportation, but from the results of the study it can be said that it is minimally exceeded only on two streets by less than five decibels and on three other streets where it is equal to the permissible noise value. The main places where the most noise is generated are two-lane roads and traffic lights and roundabouts. A lot of noise is generated when there are a large number of vehicles slowing down and starting in these places. A very big plus in the fight against noise in Pila is public transportation.

Opis:
In this paper, thermal oxidation resistance of silicide-coated niobium substrates was tested in a temperature range of 1300–1450°C using an HVOF burner. Pure niobium specimens were coated using the pack cementation CVD method. Three different silicide thickness coatings were deposited. Thermal oxidation resistance of the coated niobium substrates was tested in a temperature range of 1300–1450°C using an HVOF burner. All samples that passed the test showed their ability to stabilize the temperature over a time of 30 s during the thermal test. The rise time of substrate temperature takes about 10 s, following which it keeps constant values. In order to assess the quality of the Nb-Si coatings before and after the thermal test, light microscopy, scanning electron microscopy (SEM) along with chemical analysis (EDS), X-ray diffraction XRD and Vickers hardness test investigation were performed. Results confirmed the presence of substrate Nb compounds as well as Si addition. The oxygen compounds are a result of high temperature intense oxidizing environment that causes the generation of SiO phase in the form of quartz and cristobalite during thermal testing. Except for one specimen, all substrate surfaces pass the high temperature oxidation test with no damages.

Opis:
Steam discharge produces noise due to rapid expansion and a temperature drop of ejected steam. This is why steam silencers are used to change one-stage into multi-stage expansion, which reduces the intensity of pressure and temperature drop during this process and shifts emitted noise into higher frequencies, which are easier to dampen. This paper presents a flow-acoustic numerical model of a steam silencer. It is meant to help to obtain a precise analysis of phenomena occurring in steam silencers and improve the process of designing this type of device. The model described in this paper was based on the parameters of a real working unit manufactured in the Institute of Power Engineering – Thermal Technology Branch. Most of the steam silencers are designed based on construction guidelines that have not been changed for a long time. This restrained an increase in the acoustics efficiency of the steam silencers. An improvement of their flow and acoustic properties allows for the development of smaller, more efficient, and lighter construction. The current version of the model was used for the analysis of flow and acoustic changes which occur after modifying the lower region of a shell of the steam silencer. The proposed modification allowed for a 19% increase in mass flow rate through the silencer and noise reduction in the low-frequency range.
