Among all the means of transportation, road has been described as the most important, probably because of its flexibility and its low cost in terms of construction, maintenance and usage. However, in Nigeria, road is considered to be the most dangerous means of transportation because of their bad nature such as sharp bends, narrow bridges, steep slopes and other related problems which are associated with the terrain where these roads are constructed. Road transportation therefore needs proper planning and development through the use of geo-information technologies that would ease accessibility reduces human energy and yet brings reliable and accurate information on the terrain. In this paper, Ilwis 3.5 was used to create Digital Elevation Modelling (DEM), Shadowing, 3-Dimentional View, Slope maps and river direction maps of Biu plateau to analyze the use of GIS on road planning and development on the plateau. It was revealed that the technique has great capabilities of terrain analysis as features which are deemed humanly impossible to assess are viewed as if one is at the scene which may enhance quick analysis on road transportation. It was therefore, recommended that all the stake holders in road transportation should employ the use of this geo-information techniques in terrain analysis to ease transport planning and development in the area.

Abstract Analysis of road traffic accidents revealed that most accidents are as a result of drivers’ errors. Over the years, active safety systems (ASS) were devised in vehicle to reduce the high level of road accidents, caused by human errors, leading to death and injuries. This study however evaluated the impacts of ASS inclusions into vehicles in Nigeria road transportation network. The objectives was to measure how ASS contributed to making driving safer and enhanced transport safety. Road accident data were collected, for a period of eleven years, from Lagos State Ministry of Economic Planning and Budget, Central Office of Statistics. Quantitative analysis of the retrospective accident was conducted by computing the proportion of yearly number of vehicles involved in road accident to the total number of vehicles for each year. Results of the analysis showed that the proportion of vehicles involved in road accidents decreased from 16 in 1996 to 0.89 in 2006, the injured persons reduced from 15.58 in 1998 to 0.3 in 2006 and the death rate diminished from 4.45 in 1998 to 0.1 in 2006. These represented 94.4 %, 95 % and 95 % improvement respectively on road traffic safety. It can therefore be concluded that the inclusions of ASS into design of modern vehicles had improved road safety in Nigeria automotive industry.

The rapid increase of low-cost consumer-grade to enterprise-level unmanned aerial systems (UASs) has resulted in the exponential use of these systems in many applications. Structure from motion with multiview stereo (SfM-MVS) photogrammetry is now the baseline for the development of orthoimages and 3D surfaces (e.g., digital elevation models). The horizontal and vertical positional accuracies (x, y and z) of these products in general, rely heavily on the use of ground control points (GCPs). However, for many applications, the use of GCPs is not possible. Here we tested 14 UASs to assess the positional and within-model accuracy of SfM-MVS reconstructions of low-relief landscapes without GCPs ranging from consumer to enterprise-grade vertical takeoff and landing (VTOL) platforms. We found that high positional accuracy is not necessarily related to the platform cost or grade, rather the most important aspect is the use of post-processing kinetic (PPK) or real-time kinetic (RTK) solutions for geotagging the photographs. SfM-MVS products generated from UAS with onboard geotagging, regardless of grade, results in greater positional accuracies and lower within-model errors. We conclude that where repeatability and adherence to a high level of accuracy are needed, only RTK and PPK systems should be used without GCPs.

Abstract. Depressions – inwardly draining regions of digital elevation models – present difficulties for terrain analysis and hydrological modeling. Analogous “depressions” also arise in image processing and morphological segmentation, where they may represent noise, features of interest, or both. Here we provide a new data structure – the depression hierarchy – that captures the full topologic and topographic complexity of depressions in a region. We treat depressions as networks in a way that is analogous to surface-water flow paths, in which individual sub-depressions merge together to form meta-depressions in a process that continues until they begin to drain externally. This hierarchy can be used to selectively fill or breach depressions or to accelerate dynamic models of hydrological flow. Complete, well-commented, open-source code and correctness tests are available on GitHub and Zenodo.

Air transport as an organized form of service provision, especially in passenger transport, can be important for increasing the number of foreign tourists. Globalization and the development of information technologies have contributed to the development of the business model of airlines, which has enabled a significant reduction in the cost of air travel and the accelerated development of this industry. Therefore, the emphasis is placed on the global trend of development of low-cost airlines, their way of doing business and the effects they have on the development of tourism. The increase in the number of low-budget airlines has multiple effects on the development of international tourism and passenger transport due to cheaper transport, which is made possible by improving the competitiveness of air transport after its deregulation. In addition, lower prices and a better logistical position can contribute to an increase in the number of foreign tourists and a higher income for this industry, as well as other related economic activities. The aim of this paper is to examine through theoretical and empirical insight whether there is an impact of low-cost airlines on the volume of air traffic and the intensity of passenger transport, with an emphasis on existing literature, as well as empirical confirmation on the example of Serbia. The conducted research has important implications, since in pandemic conditions, further development of low-budget airlines is expected to contribute to the recovery of air traffic and tourism.

Urinalysis simply means analysis of urine. It is an easily performed investigation that can detect a wide variety of abnormalities within a few minutes at low cost. Urinalysis is an investigation which all nurses should be competent to perform and is identified by the NMC (2007) as being an example of an essential skill nurse students should be competent to perform before entering their branch programme. Urinalysis may be performed in a wide variety of clinical settings. It should be performed on every patient entering the acute care setting. Additionally, the National Confidential Enquiry into Patient Outcome and Death (NCEPOD (2009), stresses the need for urinalysis to be performed on all emergency admissions to an acute hospital. It may also be performed in outpatient and general practice clinics, and community areas. To obtain the most accurate information from the test, students need to know how to obtain and assess a sample of urine and be aware of factors that may influence the reliability of the investigation. Urine may be tested in three different ways. ● Macroscopic urinalysis, ● Microscopic urinalysis, ● Chemical analysis. Macroscopic and chemical analysis are the investigations performed in the clinical setting which may be tested by OSCE. Microscopic investigation requires samples to be sent to a laboratory. Macroscopic analysis is the analysis of the urine by the naked eye. Chemical analysis may be performed by use of a plastic diagnostic reagent strip or ‘dipstick’ which contains small pads of chemicals which react to substances that may be found in urine. For purposes of testing urine at random, clients are asked to urinate into a clean but not sterile dry container with no precautions regarding contamination. In females in particular this may result in samples being contaminated by vaginal fluids, such as blood or mucus. Due to the risk of contamination a mid-stream specimen of urine may be required if an abnormality is found in a random sample. A mid-stream specimen requires cleaning of the external urethral meatus prior to urination, passing the first half of the bladder contents into the lavatory, and passing the second part of the urine flow into a sterile container.

Abstract. We present the developmental considerations, design, and deployment of an autonomous modular terrestrial rover for ice-sheet exploration that is inexpensive, easy to construct, and allows for instrumentation customization. Total construction cost for this rover is less than $3000, approximately one tenth the cost of existing platforms, and it can be built using facilities frequently available at academic institutions (machine shop, 3D printer, open-source hardware and software). Instrumentation deployed on this rover can be customized; the rover presented in this study was equipped with a dual-frequency GPS receiver and a digital SLR camera for constructing digital elevation models using structure-from motion (SfM) photogrammetry. We deployed this prototype rover on the Northeast Greenland Ice Stream to map local variations in snow accumulation and surface topography. The rover conducted four autonomous missions based out of the East Greenland Ice Core Project (EGRIP) camp during July 2017, measuring surface elevation transects across the hazardous ice-stream shear margins. During these missions, the rover proved capable of driving over 20 km on a single charge with a drawbar pull of 25°N, sufficient to tow commercial ground-penetrating radars. The rover also acquired photographs that were subsequently used to construct digital elevation models of a site monitored for spatiotemporal variability in snow accumulation, demonstrating adequate stability for high-resolution imaging applications. Due to its low cost, low-power requirements, and simple modular design, mass deployments of this rover design are practicable. Furthermore, operation of the rover in hazardous areas circumvents substantial expense and risk to personnel associated with conventional, crewed deployments. Thus, this rover is an investigatory platform that enables direct exploration of polar environments considered too hazardous for conventional field expeditions.
