Correlates of Pedestrian and Cyclist Falls in Snowy and Icy Conditions

Existing international studies consistently report increased numbers of pedestrian and cyclist falls in the winter months, particularly in icy/snowy conditions. Until now, reliable information on the factors contributing to these falls has been rare. This study investigates possible correlates of pedestrian and cyclist falls in icy/snowy conditions in Germany and takes into consideration factors such as behavior and surface conditions with the aim to develop recommendations for improving safety for vulnerable road users. As part of this study, 3,300 people in online surveys and 2,100 in field surveys were asked about their experiences and opinions in relation to icy/snowy conditions and winter maintenance. Of those surveyed, 1,100 pedestrians and 2,200 cyclists also reported details about their most recent fall within the last five years. Furthermore, the behavior of 7,000 pedestrians and 4,500 cyclists was observed with cameras in both snowy and other weather conditions. The presence of snow/ice itself was indicated as a reason for three quarters of pedestrian and two thirds of cyclist falls in snowy/icy conditions. For nearly all of the falls in snowy/icy conditions, surfaces were reported as poorly cleared or not cleared at all. Compared to other weather more pedestrians fell on sidewalks and less while crossing the street during snowy and icy conditions. Cyclists increased their speed on downhill sidewalks in dry conditions and reduced their speed in snowy conditions compared to flat or uphill sidewalks. Most cyclists chose to cycle on sidewalks instead of their own dedicated, but not maintained, facilities (even though they are obliged by law to cycle on the carriageway in such cases). In snowy/icy conditions, 5 % of pedestrians varied their pace or step sequence and 8 % of cyclists drove "wavy lines" or made obvious corrective steering movements, particularly on poorly maintained facilities (compared to very few of such observations in other weather conditions). Half of the respondents rated the winter maintenance at pedestrian facilities to be good and three quarters rated the maintenance at public transport stops as good. In contrast, only 12 % rated winter maintenance on cycling facilities as good. Reasons for not being satisfied included poor quality, delay and insufficient frequency of cleaning as well as the type of grit used. The lack of seamless reliably-cleaned cycle routes was listed as a major problem by most respondents. More than 50 % claimed that previously cleaned pedestrian or cyclist facilities were re-covered with snow from clearing the carriageway.

Novel treatments in epilepsy guided by genetic diagnosis

In recent years, precision medicine has emerged as a new paradigm for improved and more individualized patient care. Its key objective is to provide the right treatment, to the right patient at the right time, by basing medical decisions on individual characteristics, including specific genetic biomarkers. In order to realize this objective researchers and physicians must first identify the underlying genetic cause; over the last 10 years, advances in genetics have made this possible for several monogenic epilepsies. Through next generation techniques, a precise genetic aetiology is attainable in 30–50% of genetic epilepsies beginning in the paediatric age. While committed in such search for novel genes carrying disease‐causing variants, progress in the study of experimental models of epilepsy has also provided a better understanding of the mechanisms underlying the condition. Such advances are already being translated into improving care, management and treatment of some patients. Identification of a precise genetic aetiology can already direct physicians to prescribe treatments correcting specific metabolic defects, avoid antiseizure medicines that might aggravate functional consequences of the disease‐causing variant or select the drugs that counteract the underlying, genetically determined, functional disturbance. Personalized, tailored treatments should not just focus on how to stop seizures but possibly prevent their onset and cure the disorder, often consisting of seizures and its comorbidities including cognitive, motor and behaviour deficiencies. This review discusses the therapeutic implications following a specific genetic diagnosis and the correlation between genetic findings, pathophysiological mechanisms and tailored seizure treatment, emphasizing the impact on current clinical practice.

Effects of ozone pollution on phosphorus absorption and distribution in different varieties of wheat

With the aid of the Free-Air Ozone Concentration Enrichment(O3-FACE) system,effects of elevated atmospheric ozone on the biomass of five varieties of wheat(Tritcium aestivum L.) and phosphorus(P) uptake and distribution in wheat plant were investigated in Yangtze River delta.The results showed that the 50% increasing ozone concentration differently influenced the biomass of root and shoot of all wheat.Ozone elevation significantly decreased the yield of yangmai 16,yannong 19 and jiaxing 002 by 13.2%-35.7%,but had no significantly effect on yield of yangmai 15 and yangfumai 2.Elevated ozone decreased P content of root and shoot of all wheat,however no significant difference in the grain was found.Ozone elevation decreased P accumulation in the root and grain,and promoted P turnover from root to shoot,which increased the proportion of P in the grain to all biomass.Elevated ozone decreased partial productivity of phosphorus of yangmai 16,yannong 19 and jiaxing 002 by 9.0-23.8 kg/kg P2O5,and significantly decreased utilization efficiency of phosphorus of yangmai 16,yannong 19 and jiaxing 002 by 8.2%-20.2%;however,there was no significant effect on yangmai 15 and yangfumai 2.It is quite obvious that elevated ozone pollution has a potential risks to change the matter distribution of wheat and influence phosphorus turnover in soil-plant system.
Tourist purchases in a destination: what leads them to seek information from digital sources?

PurposeIn a context where retail stores are closing down and high streets are declining, the purpose of this paper is to analyse on-site shopping by tourists. This work identifies the drivers that lead tourists to use digital information sources at the beginning of the shopping process. Understanding these drivers can help destination managers and retailers encourage tourists to shop.Design/methodology/approachA personal survey was conducted in a Spanish city noted for its shopping facilities (Logroño), using a sample of 430 tourists with purchase intention. The survey was designed based on the extended unified theory of acceptance and use of technology (UTAUT2) model. A multivariate analysis, based on structural equation modelling, was carried out using partial least squares (PLS), based on variance.FindingsThe study’s finding is that performance expectancy, effort expectancy, social influence, facilitating conditions and habit influence intention to use digital sources of information to make purchases in a destination. Tourists prioritise utilitarian over hedonic motivations in the intention to use digital sources of information in tourist shopping.Originality/valueIt has been recognised that tourists are the perfect target to revitalise on-site shopping and, therefore, destinations must provide attractive shopping experiences from the outset. Prior to purchase, the search for available information is the first stage of the tourist shopping journey. Although many studies have analysed tourist shopping behaviour, none have focused, using the UTAUT2, on the digital information sources tourists consult pre-purchase. This research develops understanding of tourist shopping behaviour in this new technological context. This can help retailers/destinations provide better services and optimise the shopper's experience from the first stage of the process.

The Nexus of Sophisticated Digital Assets with Economic Policy Uncertainty: A Survey of Empirical Findings and an Empirical Investigation

This paper sets out to explore the nexus between economic policy uncertainty (EPU) and digital currencies. An integrated survey takes place based on eleven primary studies. Furthermore, an econometric analysis is conducted by the threshold ARCH, simple asymmetric ARCH and non-linear ARCH specifications covering the bull and the bear markets as well as the highly volatile period up to the present. Threshold ARCH is found to provide the best fit for estimations. Outcomes reveal that Bitcoin is strongly connected with EPU while Ethereum and Litecoin are not but are strongly linked with Bitcoin performance. Moreover, weak negative effects of the VIX on both cryptocurrencies are detected while oil exerts weak positive impacts on Ethereum. Overall, Ethereum and Litecoin could serve for diversifiers against Bitcoin or hedgers against traditional assets during highly stressed periods with the advantage of not being affected by economic policy uncertainty news.
The Urban and Peri-Urban Farms (UPFs) Relational Model: The Case of Greater Poland Voivodeship, Poland

Different studies demonstrate that urban and peri-urban agriculture (UPA) operate in so-called alternative food networks (AFNs). However, very little is known about UPA’s relational business models. Therefore, this paper investigates how the urban and peri-urban farms (UPFs) form business relationships in food networks. Their business and social relationships are much more comprehensive than traditional transactional relationships. Therefore, this study aims to delimitate the relational model of UPFs. The managers and owners of nine UPFs in Greater Poland Voivodeship, Poland, in 2019 and 2020 were investigated. To this end, we employed a triple triangulation approach—methodological, theoretical, and investigator. The study refers primarily to the theory of inter-organisational relations (IORs); the empirical analysis adopts a network approach and activities–resources–actors (ARA) model framework. The study identifies UPFs business relationships and the main features of their networks, which led to the development of a conceptual relational UPFs model. This shows the diversification of activities, the competitiveness of resources and formality of organisational structures as a basis of a farm business, the integration of activities, the sharing of resources, and the collaboration of actors as the basis of the relationship. Finally, this shows the joint nature of activities—locality of resources and mutual trust among actors—as the basis of UPFs networking.
Evaluating Nigeria’s residents perception and willingness to live in telecommunication mast locations

ABSTRACT Studies have shown that emitted electromagnetic field from telecommunication tower is possibly a threat to residents’ health within the mast location. However, Nigerian residents’ perception to live in mast location is yet to be researched in detail. This study examined the factors that influence residents’ perception and willingness to live in telecommunication mast locations and proffer possible solutions to mitigate residents’ concerns regarding likely health hazards. This was achieved consecutively. First, the developed questionnaire survey was conducted with 420 respondents, drawn from the six south-south states in Nigeria. This includes residents, academicians, environmentalists, government agencies, and medical experts. Second, results from the quantitative phase were further analyzed via face-to-face interviews in conjunction with observation in selected 40 mast stations across the research area. Factors that influence resident’s willingness to live near the telecommunication masts were identified and grouped into three (physical, health, and environmental factors). As part of the study’s implications, findings from this paper will enhance policymakers and other stakeholders in decision-making concerning resident’s perception to live in mast locations. The government should set up a regulatory agency for non-ionizing radiation protection with a mandate, among others were proffered to mitigate possible health threats and concerns of the residents.
Abraham model expressions for describing water-to-organic solvent and gas-to-organic solvent partition coefficients for solute transfer into anhydrous poly(ethylene glycol) dialkyl ether solvents at 298.15 K

ABSTRACT Henry’s law constants and infinite dilution activity coefficients were compiled from the published chemical and engineering literature for gaseous solutes and organic liquids in butyl diglyme, butyl triglyme and tetraglyme. The published literature values were converted into water-to-liquid and gas-to-liquid partition coefficients using standard thermodynamic relationships. The calculated partition coefficients were correlated mathematically with the Abraham solvation parameter model. The derived Abraham model correlations can be used to predict the partitioning behaviour of additional solutes into dry, anhydrous butyl diglyme, butyl triglyme and tetraglyme.
Thermal efficiency improvement of a solar desalination process by parabolic trough collector

Nexus water/energy security is one of the main global challenges for the future generation. Solar distillation (thermal process) represents a sustainable solution to water shortages and energy crisis in the world especially in the Middle East and North Africa region. The technique is based on a evaporation–condensation process via heat delivery through a cylindrical parabolic collector to a thermal energy storage, in the form of sand integrated into the solar still, to maximize water production efficiencies. It is a technically feasible and operational method. Results suggest that the additional solar collector flux has a direct impact on the increase in average sand and seawater temperature particularly over the period between 12 p.m. and 4 p.m. Seawater temperature increases by >26.6%. The energy stored quantity delivered for the distiller basin grows proportionality with the sand temperature, which is depending directly for the solar collector absorber temperature. The difference between the both temperatures defines a decreasing rate of −19%. The daily water production by the hybrid solar distiller is 6.5 l/day, it represents an increase of +91% compared to the traditional concrete solar still production (3.4 l/day), for the same geometry and meteorological conditions.
Seasonal abundance of Cotesia ruficrus (Hymenoptera: Braconidae) and its host tea looper, Hyposidra talaca (Lepidoptera: Geometridae) in tea ecosystem

Abstract Investigations were undertaken for a better understanding of seasonality, interaction with tea ecosystem, and parasitic impact of an endoparasitoid Cotesia ruficrus (Haliday) (Hymenoptera: Braconidae) on the destructive tea looper Hyposidra talaca (Walker) (Lepidoptera: Geometridae). The population abundance of C. ruficrus was noticed as high in the months of pre-winter and spring seasons which was coincided with the population increase of H. talaca. C. ruficrus found to foraging and collecting nectar from the flowers of Lantana camera L. , Moringa oleifera Lam. , and Clerodendron infortunatum L. associated with the tea ecosystem. The life table parameters including intrinsic rate of natural increase (rm ) and net reproductive rate (Ro) of C. ruficrus were 0.203 per day and 41.11 female offspring/female, respectively, with the gross reproductive rate (∑mx) 50.09 eggs/female. The parasitic impact of C. ruficrus has significantly affected the food consumption and development of H. talaca. Resultantly, a drastic reduction in body weight, changes in differential hemocyte count (DHC), and morphology of hemocytes were observed in parasitized host larvae. Toxic effect of quinalphos and thiamethoxam on C. ruficrus showed 100% mortality followed by bifenthrin > deltamethrin > emamectin benzoate > flubendiamide > fenpyroxymate after 72 h of the application.
A Novel Optimization Approach for Sub-Hourly Unit Commitment With Large Numbers of Units and Virtual Transactions

Unit Commitment (UC) is an important problem in power system operations. It is traditionally planned for 24 hours with one-hour time intervals. To accommodate the increasing net-load variability, sub-hourly UC has been suggested for improved system flexibility. Such a problem is larger and more complicated than hourly UC because of the increased number of periods and reduced unit ramping capabilities per period. The computational burden is further exacerbated for systems with large numbers of virtual transactions leading to dense transmission constraint matrices. Consequently, the state-of-the-art and practice method, branch-and-cut (B&C), suffers from poor performance. In this paper, our recent Surrogate Absolute-Value Lagrangian Relaxation (SAVLR) is enhanced by embedding ordinal-optimization concepts for a drastic reduction in subproblem solving time. Rather than formally solving subproblems by using B&C, subproblem solutions satisfying SAVLR's convergence condition are obtained by modifying solutions from previous iterations or solving crude subproblems. All virtual transactions are included in each subproblem to reduce major changes in solutions across iterations. A parallel version is also developed to further reduce the computation time. Testing on MISO's large cases demonstrates that our ordinal-optimization embedded approach obtains near-optimal solutions efficiently, is robust, and provides a new way of solving other MILP problems.
Overview of COVID-19 Disease: Virology, Epidemiology, Prevention Diagnosis, Treatment, and Vaccines

Coronaviruses belong to the “Coronaviridae family”, which causes various diseases, from the common cold to SARS and MERS. The coronavirus is naturally prevalent in mammals and birds. So far, six human-transmitted coronaviruses have been discovered. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first reported in December 2019 in Wuhan, China. Common symptoms include fever, dry cough, and fatigue, but in acute cases, the disease can lead to severe shortness of breath, hypoxia, and death. According to the World Health Organization (WHO), the three main transmission routes, such as droplet and contact routes, airborne transmission and fecal and oral for COVID-19, have been identified. So far, no definitive curative treatment has been discovered for COVID-19, and the available treatments are only to reduce the complications of the disease. According to the World Health Organization, preventive measures at the public health level such as quarantine of the infected person, identification and monitoring of contacts, disinfection of the environment, and personal protective equipment can significantly prevent the outbreak COVID-19. Currently, based on the urgent needs of the community to control this pandemic, the BNT162b2 (Pfizer), mRNA-1273 (Moderna), CoronaVac (Sinovac), Sputnik V (Gamaleya Research Institute, Acellena Contract Drug Research, and Development), BBIBP-CorV (Sinofarm), and AZD1222 (The University of Oxford; AstraZeneca) vaccines have received emergency vaccination licenses from health organizations in vaccine-producing countries.
