    In one of the domestic rooms attached to the North-West Church at Hippos (Sussita), at least three ceramic pithoi were found, all of them in secondary use, possibly for the processing (storing?) of lime. One of them bore an inscription in Greek, scratched into its surface, which turned out to be an acclamation for the circus faction of the Blues. This interesting addition to the corpus of the factions’ inscriptions from Syro-Palestine is also lending the dating to the original period of the pithos’ use, which cannot be later than the Islamic conquest of the region in ad 636/638

    Kyphoscoliosis — what can we do for respiration besides NIV?

    Kyphoscoliosis is a significant clinical problem with no precise guidelines for management, especially concerning respiratory pathology. No exhaustive systematic review has yet been performed. The aim was to conduct a systematic review of available data concerning the pathophysiology and treatment of kyphoscoliosis. An electronic systematic search compliant with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted. The Pubmed database was examined and the search was updated to November 10, 2016. In total, 188 articles were screened, and 52 full text articles were then assessed for eligibility. As 24 of them met exclusion criteria, only 28 articles were further analysed. These articles were published in 18 journals from 1959 to 2015, with 25 being original studies, and one randomised control trial. The total corpus included 18 prospective studies, 7 retrospective studies and 3 case reports. KS is a significant complex, multidisciplinary clinical problem. The heterogeneous nature of the majority of published studies prevents unequivocal conclusions being drawn. Despite a great progress in knowledge about the respiratory system functioning and pathology in KS, the treatment seems to be not yet quite yet satisfactory. Therefore, there is a strong need for large prospective studies and unified clinical guidelines in on the management of this group of patients

    Abrasive waterjet (AWJ) forces-indicator of cutting system malfunction

    Measurements enabling the online monitoring of the abrasive waterjet (AWJ) cutting process are still under development. This paper presents an experimental method which can be applicable for the evaluation of the AWJ cutting quality through the measurement of forces during the cutting process. The force measuring device developed and patented by our team has been used for measurement on several metal materials. The results show the dependence of the cutting to deformation force ratio on the relative traverse speed. Thus, the force data may help with a better understanding the interaction between the abrasive jet and the material, simultaneously impacting the improvement of both the theoretical and empirical models. The advanced models could substantially improve the selection of suitable parameters for AWJ cutting, milling or turning with the desired quality of product at the end of the process. Nevertheless, it is also presented that force measurements may detect some undesired effects, e.g., not fully penetrated material and/or some product distortions. In the case of a proper designing of the measuring device, the force measurement can be applied in the online monitoring of the cutting process and its continuous control.Web of Science147art. no. 168

    Experience Gained When Using the Yuneec E10T Thermal Camera in Environmental Research

    Thermal imaging is an important source of information for geographic information systems (GIS) in various aspects of environmental research. This work contains a variety of experiences related to the use of the Yuneec E10T thermal imaging camera with a 320 × 240 pixel matrix and 4.3 mm focal length dedicated to working with the Yuneec H520 UAV in obtaining data on the natural environment. Unfortunately, as a commercial product, the camera is available without radiometric characteristics. Using the heated bed of the Omni3d Factory 1.0 printer, radiometric calibration was performed in the range of 18–100 °C (high sensitivity range–high gain settings of the camera). The stability of the thermal camera operation was assessed using several sets of a large number of photos, acquired over three areas in the form of aerial blocks composed of parallel rows with a specific sidelap and longitudinal coverage. For these image sets, statistical parameters of thermal images such as the mean, minimum and maximum were calculated and then analyzed according to the order of registration. Analysis of photos taken every 10 m in vertical profiles up to 120 m above ground level (AGL) were also performed to show the changes in image temperature established within the reference surface. Using the established radiometric calibration, it was found that the camera maintains linearity between the observed temperature and the measured brightness temperature in the form of a digital number (DN). It was also found that the camera is sometimes unstable after being turned on, which indicates the necessity of adjusting the device’s operating conditions to external conditions for several minutes or taking photos over an area larger than the region of interest

    Remote Sensing Using Unmanned Aerial Vehicles for Tourist-Recreation Lake Evaluation and Development

    No full text
    This article concerns the use of remote sensing methods to assess the potential of tourism and recreation of lakes by using unmanned aerial vehicles as a tool that offers new measurement possibilities in such difficult areas to research as river and lake systems. For the purpose of the study, air surveys over three lakes used for tourism and recreation purposes were planned and carried out. These were the following lakes: Swarzędzkie, Wolsztyńskie and Zbąszyńskie located in western Poland. The photos were taken with a RGB and a multispectral cameras. On the basis of calculated orthophotomaps and digital surface models, anthropogenic and natural values were assessed. The examples of the research show the versatile possibilities of using drones dependent on the type sensor used. Remote sensing performed from the deck of an unmanned aircraft is widely used in the study of lakes and is an alternative to existing land and water research methods

    Attempt to Combine Physicochemical Data with Thermal Remote Sensing to Determine the Extent of Water Mixing between River and Lake

    The mixing of river and lake waters is important for the functioning of a reservoir, especially in the case of shallow polymictic reservoirs such as Lake Swarzędzkie. The extent of this mixing depends largely on the river flow rate. In lakes, which rivers with low flow values flow through, it should be expected that the flow currents only reach the narrow zone adjacent to the mouth of the river to the lake. The water of rivers generally has different chemical compositions and physicochemical parameters in relation to lake water. Therefore, to determine the range of the river in the lake and characterize the water mixing, measurements of temperature, electrolytic conductivity, and the concentrations of selected chemical elements were made in the estuary zone and at other points located on the lake and on the river near the tributary. In addition, the values and directions of horizontal currents were determined, and thermal photos were taken from a low-altitude ceiling

    Study of the possibility of using dynamic imagery (video) from a low level (BSP) for photogrammetric studies

    The use of unmanned aerial vehicles is becoming more and more popular for making high-altitude and orthophotomap models. In this process, series of images are taken at specific intervals, usually lasting several seconds. This article demonstrates the ability to make models and orthophotomaps from dynamic images – video recorded from UAV. The best mutual coverage of photographs was indicated (95–96%) and the photogrammetric process for joining images was presented, through the creation of a point cloud to obtain a digital terrain model and the orotfotomap. The data was processed in 150 different variants and the usefulness of this method was demonstrated. Problems and errors that may occur during the processing of recorded image data are also described
