“…PTSs are rapid automated delivery systems that can efficiently transport drugs, medical and patient's reports, X-ray films, tissue samples and blood specimens to and from laboratories, pharmacies, nurse's stations, blood banks and the emergency department [1]. However, the transport of blood samples from the phlebotomy site to the core laboratory still remains the most common use of PTS.…”

Background: Pneumatic tube system (PTS) is a widely used method of transporting blood samples in hospitals. The aim of this study was to evaluate the effects of the PTS transport in certain routine laboratory parameters as it has been implicated with hemolysis. Methods: A systematic review and a meta-analysis were conducted. PubMed and Scopus databases were searched (up until November 2016) to identify prospective studies evaluating the impact of PTS transport in hematological, biochemical and coagulation measurements. The randomeffects model was used in the meta-analysis utilizing the mean difference (MD). Heterogeneity was quantitatively assessed using the Cohran's Q and the I 2 index. Subgroup analysis, meta-regression analysis, sensitivity analysis, cumulative meta-analysis and assessment of publication bias were performed for all outcomes. Results: From a total of 282 studies identified by the searching procedure, 24 were finally included in the metaanalysis. The meta-analysis yielded statistically significant results for potassium (K) [MD = 0.04 mmol/L; 95% confidence interval (CI) = 0.015-0.065; p = 0.002], lactate dehydrogenase (LDH) (MD = 10.343 U/L; 95% CI = 6.132-14.554; p < 10

“…Modern transportation ways (including automobile, train, airplane and ship) had changed this sector dramatically by minimizing the time taken and increasing the number people as well as animal and amount of goods to large extent and it is always going under improvement. Until today the main problem of these transportation ways is their dependence on non-renewable energy sources which are not environmentally friendly [36] [37]. Therefore, new technologies with excellent efficient and high speed accompanied with environmentally friendly manner must be developed.…”

The phenomenon of zero resistance below certain low temperature (critical temperature) leads to limitless current which implies that no dissipation in electrical energy for this occurrence. This property is immediately followed by expulsion of magnetic field from the interior of a material if this material is placed in external magnetic while it is below this low temperature. Materials that have these unique properties when they are below their critical temperature are superconductor materials which were discovered in 1911 by famous Dutch physicist H. K. Onnes. In addition to the above mentioned properties, superconductors have many exceptional positive properties and thus have excellent potentials for applications in every sector. The main problem of these materials is their low temperature which needs refrigerator for their applications elsewhere which is too costly compared to conventional conductors. Even though having room temperature superconductors is still a dream, if it is achieved we can extract energy from these materials with very low cost. In this review history of superconductors, their type and some of their applications have been considered.

“…Transportation of capsules through pipelines has been extensively used in various industries. These capsules are typically hollow containers filled with minerals [1], radioactive materials [2], waste [3,4], or other goods [5][6][7][8]. As air is readily available, pneumatic capsule pipelines (PCPs) has drawn substantial attention and have been successfully used in mineral industries, tunnel construction, waste disposal facility and hospitals [2][3][4][5][6][7][9][10][11][12][13][14][15][16][17].…”

Pneumatic conveying pipelines (PCPs) provide an effective manner for long-distance transport of capsules because of their advantages in high speed, superior safety, and full automation. For better development of PCPs, a system-level simulation tool is desired, but not yet available. In this work, a new 1D model describing systemic dynamics of airflow and capsule movement in PCPs is presented, and 3D simulation is proposed to obtain the characteristic coefficients in the 1D model. The complete model accounts for those phenomena that most profoundly affect the performance of PCPs, such as the 3D layout of the pipeline, the geometry of capsules, as well as the compressibility of air in a long pipeline. A finite volume method is also presented to numerically calculate the model equations, and thereby realize the successful system-level simulation of practical PCPs for the first time. Experimental data were used for validation. For a 550 m-long and small-diameter (27.86 mm) PCP, the errors of predicted conveying times were within 4.43%. For another 30 m-long and large-diameter (125.6 mm) PCP, the errors of predicted conveying time and maximum capsule velocity were within 1%. By enabling readily and accurate prediction of the conveying process, the method provides a feasible tool for the design and application of PCP systems.
