Abstract: Freight conveyances on signalized city street are perceived as path hindrances all through the span of conveyance. Traffic sticking related with metropolitan cargo conveyances has acquired expanding consideration as of late. As traffic architects and organizers are entrusted with discovering answers for achieve complete interest all the more economically with confined street limit. Despite the fact that trucks make up just a minor extent of vehicular traffic, however they gain a more prominent measure of the absolute expense of postponements. Developing discussion of arrangements to move conveyances to off hours are proposed to moderate the impacts of on traffic sticking. This paper audits on how the cargo conveyances effect on street limit and postpone time. This paper reviews various related research paper that how actually freight delivery effect on street capacity of road and also greater impact on travel time. Because if proper planning is not going to done it leads to traffic congestion problem. Keywords: Signalized City road, Cargo delivery, Capacity, Delay time

ABSTRACTThe Scottish Hydrometric Network consists of a number of river gauging stations which have been located at sites considered suitable to provide long term flow records. Economic recession has placed some stress on the gauging programme, and has given rise to extensive closures of gauging stations in England and, to a minor extent so far, in Scotland. The way in which the network became established provides a mixture of strengths and weaknesses which could have unpredictable consequences in an adverse economic climate. Changing technology provides some opportunity to reduce the cost of data acquisition and improve the deployment of manpower, while maintaining data standards. In these changing circumstances, particularly with extensive use of computer systems, it is important that standards are established for data returned to the Water Archive and that the network is not allowed to degenerate by default.

This paper extends Vickrey’s point-queue model to study ridesharing behavior during a morning commute with uncertain bottleneck location. Unlike other ridesharing cost analysis models, there are two congestion cases and four dynamic departure patterns in our model: pre-pickup congestion case and post-pickup congestion case; both early pattern, both late pattern, late for pickup but early for work pattern, and early for pickup but late for work pattern. Analytical results indicate that the dynamic property of the mixed commuters equilibrium varies with the endogenous penetration rates associated with ridesharing commutes, as well as the schedule difference between pickup and work. This work is expected to promote the development of ridesharing to mitigate the traffic congestion and motivate related research of schedule coordination for regulating the ridesharing travel behavior in terms of the morning commute problem.

Abstract At present, in the New World, C. arizonica and its varieties are of low economic importance, but they are sometimes cut for fenceposts, fuelwood and lumber, and recently they have become popular as Christmas trees. By contrast, the Arizona cypress (C. arizonica var. arizonica) and the smooth cypress (C. arizonica var. glabra) are widespread in Europe and are used for landscaping, erosion control, windbreaks, and to a minor extent for lumber.

The recovery in the OECD area gathered pace in the second quarter, when its total GDP probably increased by as much as 1 per cent. The rise was, however, heavily concentrated in North America and particularly the US. There may well have been a slight fall in Western Europe, where the level of industrial production hardly changed and increases in gross product in West Germany and, to a minor extent, in France were outweighed by falls in Italy and (according to the expenditure measure) the UK.

Policies that aim at bringing about a digital transformation (seek to) create the conditions for particular spatial development trajectories. Yet, the understandings, explicit and implicit, of space advanced by digital agendas have remained rather underexposed to date. This paper addresses this gap by developing a Foucauldian-inspired discourse-analytical framework and applies it to the programme of ‘Digital Hungary’. It is argued that policies of digitalisation in Hungary only to a minor extent consider the spatial dimension, and their impact potentially undermines the declared aims of spatial development at different scales.

In the article, the bryophytes of the upper reaches of the Western Bug River, which is physically and geographically located within Male Polissya, partly Roztochia, and to a minor extent in the Gologoro-Voronyatsky denudo-structural hills, have been studied. Based on our survey, a list of the bryophytes has been compiled for the first time. Ecological features, substrate preferences and life forms of the bryophytes have been analysed. According to the ecological features, subheliophytes (30.9%) and hemisciophytes (30.9%) predominate in the spectrum of heliomorphs; mesophytes (29.7%), hygromesophytes (21.2%) and xeromesophytes – in the spectrum of hydromorphs (19.4%); cold-tolerant species (59.4%) – in the spectrum of thermomorphs. Based on the analysis of the substrate preferences of the bryophytes, the following groups were identified: epigeans (116 species), epixils (56 species), epiphytes (46 species), epiliths (43 species), aquatic (22 species). The prevailing life forms are turf (30.3%), rough mat (18.2%), weft (15.2%), tuft (10.3%) and smooth mat (9.7%). 3 species that are officially recognised as rare and 16 species that are recognized as regionally rare have been found. In the group of bryophytes associated with wetland ecosystems, 2 officially rare and 6 regionally rare species were found in the study area. Given the large areas of drained land in Lviv Region, these species are of particular value, especially in the context of conservation of the biodiversity and protection of the valuable natural areas in accordance with the Development Strategy of Lviv Region by 2027.

This article analyses the emergence and development of the study of gender in modern Greek historiography in the broader sense, exploring works that incorporate, even to a minor extent, the gender factor. It shows that despite the manifold barriers that gender historians have faced, there has been a slow but steady process of diffusion of gender in modern Greek historiography in general. The article also shows that historical research on gender relations in Greece initially focused on the study of women, historicising, however, their relations with men. Thus, in line with what Kantsa and Papataxiarchis argue about the relevant scholarship at the international level, no linear transition from the study of women to the examination of gender relations occurred. What has transpired in the last two decades, however, is that the relevant historiography has gradually broadened to encompass a more systematic analysis of the (re)making of masculinities. It has also been enriched by the study of the intersection of gender and age as well as of transnational flows and their impact on gender, tendencies that have been slightly neglected in other reviews of the study of gender in Greek historiography.

The previous studies on asphalt mix and asphalt with waste engine oil addition indicate the possibility of using this type of waste material for the construction of road pavements. The research presented in this paper aimed at the preliminary assessment of possible waste engine oil (WEO) addition to the asphalts foamed with water-soaked zeolites. In this research, synthetic zeolite Na-P1 and natural clinoptilolite were used. In order to improve the foaming effect, the zeolites were soaked with water before dispensing to the asphalt, in the amount of 75% asphalt weight for Na-P1 and 25% for clinoptilolite. The tests were performed for one type of waste engine oil—5W40 and two type of binders: 20/30 and polymer modified 25/55-60. The asphalt parameters such as the dynamic viscosity, penetration and softening point were determined with the addition of WEO and zeolites in the concentration of 0%, 3%, 5%, 7% for both materials. It was found that the WEO addition lowers the viscosity and softening point of asphalt but increases penetration. The zeolite addition affected the change of these parameters to a minor extent or was statistically irrelevant. The chemical analysis of the asphalt samples with WEO addition performed with the X-ray Fluorescence method did not show a significant amount of heavy metals which would increase the probability of low-temperature cracking. The analysis of the results indicates the possibility of using zeolite-foamed asphalt technology with WEO addition.

Abstract Background Quantification of myocardial blood flow (MBF) with PET requires accurate attenuation correction, which is performed using a separate CT. Misalignment between PET and CT scans has been reported to be a common problem. The purpose of the present study was to assess the effect of PET CT misalignment on the quantitative accuracy of cardiac 15O-water PET. Methods Ten clinical patients referred for evaluation of ischemia and assessment of MBF with 15O-water were included in the study. Eleven different misalignments between PET and CT were induced in 6 different directions with 10 and 20 mm amplitudes: caudal (+Z), cranial (− Z), lateral (±X), anterior (+Y), and anterior combined with cranial (+ Y and − Z). Blood flow was quantified from rates of washout (MBF) and uptake (transmural MBF, MBFt) for the whole left ventricle and the three coronary territories. The results from all misalignments were compared to the original scan without misalignment. Results MBF was only minorly affected by misalignments, but larger effects were seen in MBFt. On the global level, average absolute deviation across all misalignments for MBF was 1.7% ± 1.4% and for MBFt 5.4% ± 3.2 Largest deviation for MBF was − 4.8% ± 5.8% (LCX, X + 20) and for MBFt − 19.3% ± 9.6% (LCX, X + 20). In general, larger effects were seen in LAD and LCX compared to in RCA. Conclusion The quantitative accuracy of MBF from 15O-water PET, based on the washout of the tracer, is only to a minor extent affected by misalignment between PET and CT.
