Today’s economic growth is not promising without air transport, up-to-date airports infrastructure, efficient and safe airline services and international air transport networks. According to wb [1], 40% of the world-wide tourists travel by air transport. The main aim of this study is to analyze the literatures of air transport and economic growth study. A systematic literature review (SLR) method was used in order to examine related articles from AbDC list journals which are ranked on A*, A or b, published in period 1992-2018. This study gives a summary of the trends and research themes which have been identified. Key scholars, as well as their approaches and locations and citations are also mapped. The findings of this study show that there is a growing interest in researching and publishing on Air transportation and economic growth. This study fills a deficiency in specialized literature concerning air transportation in developing countries and provides a foundation for future research in the field of air transportation.

Nanosecond pulse generation is demonstrated in a mode-locked erbium-doped fiber laser(EDFL) utilizing a samarium oxide(Sm2O3) film. The Sm2O3 film exhibits a modulation depth of 33%, which is suitable for modelocking operation. The passively pulsed EDFL operates stably at 1569.8 nm within a pumping power from 109 to 146 m w. The train of generated output pulses has a pulse width of 356 nm repeated at a fundamental frequency of 0.97 MHz. The average output power of 3.91 m w is obtained at a pump power of 146 m w, corresponding to 4.0 nJ pulse energy. The experimental result indicates that the proposed Sm2O3 saturable absorber is viable for the construction of a flexible and reliably stable mode-locked pulsed fiber laser operating in the 1.5 m region.

The Jiaguan Formation and the underlying Feitianshan Formation(Lower Cretaceous) in Sichuan Province yield multiple saurischian(theropod–sauropod) dominated ichnofaunas. To date, a moderate diversity of six theropod ichnogenera has been reported, but none of these have been identified at the ichnospecies level. Thus, many morphotypes have common "generic" labels such as Grallator, Eubrontes, cf. Eubrontes or even "EubrontesMegalosauripus" morphotype. These morphotypes are generally more typical of the Jurassic, whereas other more distinctive theropod tracks(Minisauripus and Velociraptorichnus) are restricted to the Cretaceous. The new ichnospecies Eubrontes nobitai ichnosp nov. is distinguished from Jurassic morphotypes based on a very wellpreserved trackway and represents the first-named Eubrontes ichnospecies from the Cretaceous of Asia.

The present study evaluated the in vitro activity and in vivo efficacy of diminazene combined with chloroquine as a potential drug against Leishmania donovani. Amphotericin b was used as a positive control drug. In vitro activity involved incubation of various drug concentrations with promastigotes or vero cells in culture before determination of parasite growth inhibition or cell death while in vivo evaluations involved infection of various mice groups with virulent L. donovani parasites and treatment with test drug compounds following disease establishment. weight changes in experimental mice were also evaluated before infection and throughout the experiment. The results indicated that the diminazene-chloroquine combination was at least nine times more efficacious than individual drugs in killing promastigotes in culture. The diminazene-chloroquine combination was safer （Ld50=0.03±0.04） than Amphotericin b （Ld50=0.02±0.01）. body weight in infected mice increased significantly （P=0.0007） from day 7 to day 37 following infection （P=0.026）. However, body weight remained comparable in all mice groups during treatment （P=0.16）. The diminazene-chloroquine combination significantly reduced splenic parasite numbers as compared to individual drug therapies （P=0.0001） although Amphotericin b was still more efficacious than any other treatment （P=0.0001）. Amongst the test compounds, the diminazene-chloroquine combination showed the lowest level of IgG antibody responses with results indicating significant negative correlation between antileishmanial antibody responses and protection against disease. These findings demonstrate the positive advantage and the potential use of a combined therapy of diminazene-chloroquine over the constituent drugs. Further evaluation is recommended to determine the most efficacious combination ratio of the two compounds.

Hypersingular integral equations are derived for the problem of determining the antiplane shear stress around periodic arrays of planar cracks in a periodically-layered anisotropic elastic space. The unknown functions are directly related to the jump in the displacements across opposite crack faces. Once the integral equations are solved, crack parameters of interest, such as the clack tip stress intensity factors, may be readily *** some specific examples of the problem, the integral equations are solved numerically by using a collocation technique, in order to compute the relevant stress intensity factors.

Acid soils(ASS) are widely distributed in Australia. This has only been recognized recentlywhen intensive research on ASS has been done in this country. This paper reviews aspects concerning a)the distribution and acid potential, b) controls on acidic status, and c) problems and management of ASSin Australia It is believed that the Australian experience may be useful for other countries where potentialproblems from ASS exist but insrfficient attention was paid to them.

Laboratory animals maintained on a reduced calorie but nutritionally adequate diet have extended life spans and lowered incidences of spontaneous and chemically induced cancers compared to ad libitum- fed counterparts. Many of the effects of dietary restriction on laboratory animals have been suggested to be related to a deceleration of the aging process. The inhibition of age-related changes in xenobiotic metabolizing enzyme activities by dietary restriction has previously been reported. Alterations of these enzyme activities may cause changes in metabolic activation of carcinogens and, therefore, carcinogen-DNA binding. DNA-repair capability has also been reported to be enhanced in diet-restricted rats. Using AFb1 as a model carcinogen, we have studied in vivo and in vitro hepatic AFb1 -DNA binding, demonstrating that dietary restriction (60% of ad libitum consumption) may decrease the metabolic activation of AFb1, and subsequently reduce AFb 1-DNA binding. Our preliminary results obtained from the AFb 1-DNA binding experiments in isolated hepatocytes suggest that the observed age-dependent reduction in AFb 1-DNA binding which may be attributed to a loss of metabolic activating capability was delayed in the diet-restricted rats.
