Recently, IoT technology, low power networking technology for IoT, and geopositioning systems are very useful tools for future applications. One of the applications is the logistics system, especially for the point to point delivery. The current parcel delivery system is delivered through the logistics hub despite latent economic disadvantages in terms of delivery time and delivery distance. The major disadvantage of current hub and spoke delivery system is that individual parcels must go to the logistics hub first even if the origin and destination are nearby or within a distance that can be delivered through the hub. These sorts of delivery are inefficient and increase total expense of delivery in terms of delivery time and delivery costs. We designed a new delivery system of point to point delivery using IoT technology and end-to-end IoT platform based on ThingPlug and LoRa technology for fast delivery and less cost of delivery. We designed an IoT device that can be part of parcels or attached to parcels, which have various functionalities including the capability to understand current delivery routes with the use of geopositioning systems. In addition, we addressed the difficulties with issues such as linking IoT device into IoT platforms and designing IoT device functionalities. We also showed methods to improve the efficiency of IoT based parcel delivery systems. The proposed system may improve economics of parcel delivery system by reducing travel distance for delivery and dissipation of delivery time.

Objectives: The logistics hub construction has always been the short board of logistics network planning in China. In order to improve the decision-making efficiency of logistics enterprise’s hub selection and reduce its comprehensive operation cost, this paper establishes a cost difference model for hub-and-spoke(H-S) and point-to-point(P-P) networks considering the fixed cost of hubs, transportation and route costs based on the 0-1 integer nonlinear programming. The model aims at minimizing the cost difference between the two networks, and divides the fixed cost of the hubs into three situations: full lease, lease and self-built, and fully self-built. Finally, this paper takes tobacco transportation logistics as an example, and use particle swarm algorithm to solve the model by using tobacco transportation logistics data of a logistics enterprise in Jiangsu Province. The results show that: (i) in the case of complete leasing, the total cost of the H-S network decreases with the increase of the number of hubs, and the cost change has a point of intersection with the total cost of the P-P network;(ii) when the lease and self-build are mixed, the increase is first reduced and then increased, it is U-shaped and has a minimum value, and there are two intersections with the total cost of the P-P network;(iii) the situation of completely self-built and fully leased is just the opposite. This paper takes tobacco transportation logistics as a representative, and provides a reference for logistics companies to choose the appropriate regional logistics network structure and different pivot points.

AbstractIntroduction:The CeraFlexTM PDA occluder is a new flexible device with a unique delivery system that may be beneficial with regard to not changing the device position after releasing. We prospectively evaluate the efficacy of the device and also the device behaviour patterns during release.Methods:The study included 21 patients. Their median age was 1.2 years (from 6 months to 28 years) and weight was 9.6 kg (from 5.4 to 82 kg). All of the ducts were conical except one atypical ductus. Median ductal diameter at the pulmonary end was 3.8 mm (from 2.2 to 8.2 mm). The ductus was closed using an antegrade approach, but special attention was paid to the patterns of device behaviour during and just after releasing.Results:Three different modes of device behaviour were observed during and just after releasing: (1) Neither difficulty nor change of position in 13 patients (62%), (2) a little difficulty in releasing but no change of position in 6 (29%), and (3) change of the device position in 2 (9%). There was no residual shunt on the next day except in one patient, in whom late device embolisation occurred. The device was retrieved and another, bigger device implanted.Conclusion:The CeraFlexTM PDA occlude device seems to be safe and efficacious for patent ductus arteriosus closure. Its unique delivery system generally fixes the device in a stable position that does not change after release (91%). Minor difficulty in releasing is not uncommon; however, the major disadvantage is the need for larger sheaths for delivery.

This paper develops a new model, which allows for the co-existence of hub-and-spoke and point-to-point networks in the airline industry. Passengers are segmented between the non-stop and one-stop services. In the baseline model, the monopoly airline’s ability to segment the market and effectively set up the mixed network depends on the cost savings due to the through-hub service relative to exogenous quality difference between the one-stop and non-stop flights. Socially inefficient entry with the new non-stop service where an incumbent is operating the hub-and-spoke network is possible.

This paper evaluates the air travel tax in Europe and focuses on the tax levied in Germany. The current status quo and disputes of the air travel tax in Germany and in Europe are explored and recent decisions by the European Union Grand Court and the uropean Commission with regards to the tax are given. The paper contributes to the existing literature by analyzing the role the tax has on possible distortion of competition in Europe and argues that airlines with a point-to-point business model are placed at a competitive disadvantage with respect to their hub-and-spoke counterparts, when the tax is reasoned to encourage environmentally-balanced behavior in air travel.

A indústria de aviação civil brasileira passou por profundas mudanças, a partir dos anos de 1990, com liberalização dos mercados de transporte aéreo de passageiros, o que ocasionou importantes alterações no modelo de operação da malha aérea; sendo a mais evidente a substituição do sistema point-to-point pelas redes hub-and-spoke. A combinação do atual modelo de negócios das companhias com a configuração da infraestrutura aeroportuária e de tráfego aéreo tem se revelado altamente ineficiente. Com vistas nestes aspectos, o objetivo deste trabalho é fazer uma apreciação da concorrência no setor de aviação civil brasileiro, utilizando como unidade de análise as indústrias em rede na presença de instalações essenciais; aqui representado pelo acesso aos slots - horários de pouso e decolagem - dos aeroportos congestionados. A principal conclusão é que a distribuição de slots é de fundamental importância para estabelecer o nível de concorrência na indústria de transporte aéreo de passageiros.

The Ocular drug delivery system (ODDS) is the prominently challenging system faced by pharmaceutical researchers. Ophthalmic preparations are available in buffered, sterile and isotonic solutions. For the ocular delivery of drugs, various types of dosage forms are prepared and dispensed. As the drops are easier for the administration likewise more prescribed dosage form is the eye drop solution. For obtaining prolonged therapeutic effect ointment, suspensions and gelled systems are also used. The presence of various barriers as anatomical, physiological and physiochemical barriers makes difficulties in delivery of drugs in at the intended sites. Scientists invented alternate delivery routes to direct access at intended target sites. Second invention involves development of novel drug delivery systems providing better permeability, treatability and controlled release at target site. The liposomal delivery is beneficial because they have the ability of envelopment and both hydrophobic and hydrophilic drugs are suitable for delivery to both the anterior and posterior segment of the eye. Therefore, the uses of this alternative approach become quite a necessary. This formulation of novel devices will definitely help to the overcome ocular barriers and side effects with conventional topical drops. Current reviews on the conventional formulations of ocular delivery and their advancements followed by current nanotechnology based on the formulation developments. The recent incident with other ocular drug delivery planning consists of in situ gels, implants, contact lens and nano wafers are discussed. Drug delivery at ophthalmic route has been proven significant advancement for the future perspectives.

The article discusses a new approach to the organization of container trains based on the principles of passenger transport. The technology involves the movement of a container train on a schedule with the sale of cargo seats on the train. The train is formed at the departure station and follows the established route with stops at intermediate container terminals or stations, where the container is removed by appointment to this station and installed in the vacant place of the container by appointment to the next stations on the route. A model has been developed for forming the route of a container train with associated operations for loading and unloading containers, which allows you to find the optimal route according to the criterion of delivery time, provided that the train is loaded as much as possible on the entire route. The mathematical apparatus for constructing the model is graph theory. An algorithm for step-by-step planning of a complex of container trains on a given transport network and the established demand of regions in container transportation is proposed. The method is tested on the example of container delivery routes from China to Russia and Europe, while the considered network combines import and transit container flows with domestic and export flows formed in the Russian Federation. Given the demand matrix and the configuration of the transport network, the algorithm allowed us to create nine container trains running daily from the Eastern to Western borders of the Russian Federation, provided availability of maximum load of the container train on each section of the route. The implementation of the proposed technology will increase the competitiveness of railway container transport in both domestic and transit traffic, create conditions for containerization of additional cargo traffic by reducing delivery time and improving the quality of transport services.
