Transport Logistics

Road transport plays a significant role in the economic prosperity of each country. Every year the demand for transportation of goods increases, thus there is a need to improve the quality of transport logistics. The high rate of equipping logistics companies with cars, in recent years, is gaining a large turnover, if compared with other types of logistics in our country, thereby increasing the efficiency and quality of transport logistics, which becomes independent of other types of transport, becoming a universal, mobile transportation of goods. As a result, the need to expand roads and improve their quality increases. If you ignore the factors of improving roads, it will lead to an increase in traffic on the roads, as well as slow down the delivery time of the goods.

Abstract Background Urinary tract infection (UTI) is a common occurrence in females, during pregnancy, and in peri- and postmenopausal women. UTIs are associated with significant morbidity and mortality, and they affect the quality of life of the affected patients. Antibiotic therapy is an effective approach and reduces the duration of symptoms. Development of resistance, adverse effects of antibiotics, and other associated problems lead to establishing the research framework to find out the alternative approaches in controlling UTIs. Natural approaches have been extensively used for the management of various diseases to improve symptoms and also improve general health. Main body Different databases were employed to identify studies reporting on natural options including herbal medicines, vitamins, trace elementals, sugars, and probiotics without time limitations. Conclusion Herbal medicines can be effective at the first sign of the infection and also for short-term prophylaxis. Using vitamins, trace elementals, and/or sugars is an effective approach in preventing UTIs, and a combination of them with other antibacterial agents shows positive results. Probiotics have great potential for the threat of antibiotic over-usage and the prevalence of antibiotic-resistant microorganisms. This study may be of use in developing the efficient formulation of treatment of UTI.

The concept of transporting medical products by drone is gaining a lot of interest amongst the medical and logistics communities. Such innovation has generated several questions, a key one being the potential effects of flight on the stability of medical products. The aims of this study were to quantify the vibration present within drone flight, study its effect on the quality of the medical insulin through live flight trials, and compare the effects of vibration from drone flight with traditional road transport. Three trials took place in which insulin ampoules and mock blood stocks were transported to site and flown using industry standard packaging by a fixed-wing or a multi-copter drone. Triaxial vibration measurements were acquired, both in-flight and during road transit, from which overall levels and frequency spectra were derived. British Pharmacopeia quality tests were undertaken in which the UV spectra of the flown insulin samples were compared to controls of known turbidity. In-flight vibration levels in both the drone types exceeded road induced levels by up to a factor of three, and predominant vibration occurred at significantly higher frequencies. Flown samples gave clear insulin solutions that met the British Pharmacopoeia specification, and no aggregation of insulin was detected.

Consumer satisfaction with the services provided in a prosthetics and orthotics (P&O) facility has seldom been studied. The aim of this study was to analyze consumer satisfaction regarding the services provided by 15 P&O facilities in The Netherlands. Consumers ( n = 1,364) of these P&O facilities who were fitted with a prosthesis, orthopaedic shoes, an orthosis, or another device, were asked to rate the overall services provided and whether they were satisfied with the device provided and its delivery time. Additionally, they filled in a modified SERVQUAL questionnaire (see Appendix). Consumers gave the service provided by P&O facilities a mean overall rating of 8.1. The highest ratings were given by consumers fitted with a prosthesis (mean overall rating of services: 8.4). In total, 78% of the consumers were satisfied with the device provided and 93% with the delivery time. The results of our study showed that, on the SERVQUAL, 50% of the statements fulfilled the criteria for a satisfactory quality of the services. The overall consumer rating of the service provided by P&O facilities is high and depends on the device provided. The outcomes on the SERVQUAL were moderate. In future, it is important to study consumer satisfaction more extensively in order to improve the quality of P&O services in daily practice. Additionally, specific questionnaires need to be developed to measure all aspects of prosthetic and orthotic care, with the aim to improve the services.

Unsatisfactory quality of root canal treatment is one of the most important problems of modern dentistry. One of the reasons is the limited knowledge of dentists about the regional features of the endodontic teeth anatomy, which is becoming particularly relevant in the rise of migration activity of the Russian population. But compared to other countries, there are very few studies and publications in this field in Russia. Objective. Study the features of first molars' root canals' anatomy in patients from different regions of Russia. Materials and methods. 363 cone-beam computed tomography (CBCT) scans of the jaws of patients 26 to 64 years of age, living in Moscow and StPetersburg for at least four generations have been considered. The endodontic anatomy of 347 first molars of the upper and 611 lower jaws was studied. The number of roots and root canals, their structure and shape were determined. Results. Anatomical differences in the structure of the first molars' root canals were established in residents who resided in Moscow and StPetersburg for several generations. Variations in the number of roots and root canals were found in the upper jaw molars. As for the canal-root system of the lower molars, most often they were characterised by different variants of the cross-section and the number of canals in the distal root. Conclusions. The results of the study can be used in practical dentistry, as they allow the dentists of StPetersburg and Moscow to expand the current understanding of the root system structure and the frequency of possible variations in these regions.

<p>Bridges are composed by many structural members which interact with each other to resist against various load combinations. Considering damage repair of one of its structural members, the relationship between the recovery of the individual load-carrying capacity due to the repair of a single member and the improvement of the load-carrying capacity of the structural system is not clear. In the present study, a full-scale FE analysis has been conducted for a steel I-girder bridge system with corrosion damages which have been repaired. The analysis considered, the structural system behavior, varying the repaired areas and the type of patch members. From the analytical results, it was found that, compared to the method in which the damaged portion is completely repaired, the amount of repair can be reduced by taking into account the structural system behavior and partially repair both the damaged and the adjacent intact girders.</p>

Abstract The issue of quality is a very important aspect of the operation of transport companies. In relation to the area of their activity it primarily focuses on the quality of services provided, which can be verified e.g. on the basis of timeliness of deliveries or accepted complaints. This allows for examining the quality after providing the service in order to take future pro-quality actions. However, is it possible to affect the quality of services provided before their provision? The transport process itself is preceded with a range of actions taken within the framework of detailed planning and organization, which can significantly influence the quality of services. The decisions made at the management level are conditioned by many factors determining the course of future events, however, this is not always enough to make the process run uninterruptedly. Therefore, it is important to structure basic actions at the initial stage so as to allow the smooth conduct of the decision-making process for the specific task in order to subsequently focus on the detailed analysis of the actions planned. In the paper, the author attempts to characterize the fundamental factors affecting the decisions taken during the planning and organization of the transport process. The objective of the conducted research is to verify initial decisions and their significance for the improvement in the quality of transport services provided. There was conducted the algorithmization of actions and interpretation of their importance for the quality of decisions taken at the preparatory stage and during transport.

Difficult Part

In driving sustainable tourism, the concept of carrying capacity in tourism needs to be applied. This concept of carrying capacity gives a comprehensive emphasis in the development of tourism whether in physical, social or economic aspects. If this concept is applied, it is in determining the situation in a tourist destination whether it is still in a state that can be accepted by the stakeholders in tourism, namely tourists, locals and tour operators. In this paper, emphasis is given to social carrying capacity in tourism which is one of the parts in tourism carrying capacity. This social capacity is the most difficult part to examine because it involves unequal perceptions and views from various parties. It involves interactions between tourists and tourists that cover issues of congestion and the quality of their tourism and interactions between tourists and locals or hosts that involve issues of their quality of life. Due to that, this social capacity is quite difficult to implement in some tourist areas.
