摘要： In this paper, some distinctive features of the vertical profile of precipitable liquid water content (LWC) with considerable respect to rain rates (R) and radar reflectivity (Z) obtained in a tropical location are presented. Assessment of LWC allows applications in the specific area of flight icing severity, aviation safety as well as signals traversing through the atmosphere. The parameters were typically measured using vertically-pointing Micro Rain Radar (MRR) over a period of 2 years (2011-2012) at Akure, a tropical location of Nigeria. The radar scanned at every 10 seconds and integrated over one minute samples to reduce event logging error associated with the instrument. The vertical profile of the LWC typically reveals a prominent seasonal variation. However, majority of the LWC profiles has low LWC, less than 0.1 gm?3 while the maximum observed LWC is about 3.18 gm?3. A strong like hood relation was observed between the melting layer height and the LWC, with the LWC reaches peak at the considerable height of about 4160 m which coincides precisely with the freezing height level (rain height of ~4520 m) of the study location. Good correlation was also observed between the LWC and R in most of the heights considered. The results obtained will assist system engineers to assess the level of absorption, reflection and attenuation of electromagnetic signals as a result of precipitable LWC along the transmitting paths. The novelty of the present work is in the area of linking LWC and Z as against usual relation between Z and R.

摘要： Acid rain (AR) has been reported to induce stress in plants affecting its productivity, growth, flowering and physiology. The molecular changes induced in plants due to the effect of acid rain or acid induced orientation or chloroplast streaming remains largely unknown. Therefore, in the current study we report for the first time the static and permanent changes in the cell of the medicinal plant Bacopa monnieri L. due to sulphur-simulated acid rain (S-SiAR). AR induced effects witnessed by the reduction of the size of starch granules and chloroplast, amount of the granules per unit area, dissolving cell walls, breaking the normal fiber, salt-induced strain in the various components of the cell. Effect of starch granule and chloroplast due to S-SiAR was analyzed using light, confocal and scanning electron microscopic techniques. The elements viz. potassium and magnesium present in the chloroplasts reveal acidic pH due to effect of S-SiAR observed by the ionization of Mg and K (to Mg2+ and K+), in which K+ induced by the effects of S-SiAR revealed a net negative Nernst potential of about -87.55 mV. Calcium is mainly present on the cell walls and responsible for binding of starch granules become ionized to Ca2+ on interacting with AR indicated by the altered Nernst potential of +137.04 mV. A net potential difference may cause the above streaming of chloroplast towards the large starch granules. From this study, we report AR-induced physiological changes in medicinal plant Bacopa monnieri L. for the first time.

摘要： In this article, we consider, based on the super-diamagnetic model, the new problems of Saturn’s rings discovered by Cassini, such as: 1) anomalous purity of water ice;2) Saturn’s magnetic field alignment with the planet’s rotation axis;3) “ring rain” of the submicron particles;4) the deviation in the qualitative composition of the “rain” from the composition of the rings;5) “dirt” concentrated in the ring gaps;6) “plateaus” in Saturn’s C ring;7) age of the rings;8) roll-off in the spectrum of Saturn’s rings, and 9) “propellers” in Saturn’s A ring. Interpretation of Cassini’s observations of spectral roll-off in Saturn’s rings in the wavelength range from 100 micrometers to 0.5 mm is given. It was concluded that the substance of the rings could be in the superconducting state. An explanation of the Cassini spectral data is given using the hypothesis of the existence of a superconducting energy gap in the substance of rings.

摘要： Icing of wires is a product of rain, fog, and freezing rain, and is a common meteorological disaster in winter in Guizhou Province of China. It is extremely harmful to facilities such as power transmission and communication lines, and has caused huge economic loss up to 48.9566 billion dollars a year. Based on the meteorological records of Guizhou from 1967, we analyze the meteorological characteristics during the icing of wires, and obtain the temperature, wind speed and direction conditions of the ice accident. The icing of wires is carried out by supercooling raindrops, freezing of the clouds, freezing and spreading on the wires. Different types of supercooled raindrops and cloud freezing and freezing processes will form different types of ice accretion;wind direction and wind speed will affect the growth of ice accretion by changing the speed of sub-cooling raindrops and cloud falling. The weight of rain-type ice accretion is between 24 and 152 g, and the weight of smog-type ice is between 40 - 76 g. The average ice density of these two places can be calculated to be 0.2 - 0.5 g/cm3. The longer the icing of wires, the higher the ice disaster rate.

摘要： The overall design and system functions of the meteorological service integrated service system of the Yangtze River Basin are introduced. The system is based on CIMISS (National Integrated Meteorological Information Sharing Platform) for expansion and construction, integrating key correction forecasts, weather model comparisons, flood predictions, etc. The forecasting technology, starting from the flood control and drought relief of the service basin and the comprehensive dispatch of the reservoir, has realized the monitoring of water and rain conditions, the production of key business products, the production and distribution of integrated service products, and the quality tracking assessment. The application shows that the system can make the forecaster effectively grasp the service focus, improve the timeliness and pertinence of the service, and have a good promotion and application prospect in the basin meteorological service.

摘要： Tropical medicinal plant spices have remained underutilized in commercial food processing because of the inadequate chemical characterization of their terpene compositions. The activity of medicinal plants used in flavoring is due to their terpene contents. Terpene contents of Aframomum danielli seeds, Xylopia aethiopica fruits, Syzygium aromaticum leaves, Piper guineense seeds, and Monodora myristica seeds were determined using headspace solid-phase microextraction combined with gas chromatography-mass spectrometry. P. guineense is rich in terpinene and terpinolene (2.5 g per 100 g), S. aromaticum has caryophyllene (0.68 g per 100 g);A. danielli is rich in ocimene (1.65 g per 100 g);X. aethiopica is rich in ocimene (2.94 g per 100 g);M. mystristica is rich in delta carene (0.49 g per 100 g). Combinations of the five medicinal plant spices are being applied as flavorings in packaged tropical food.

摘要： Air pollution is one of the serious problems facing the world. This is mainly due to production and consumption of fossil fuels. Sulphur dioxide (SO2) and oxides of nitrogen (NOx) emissions could affect human health and destroy vegetation through acid deposition and cause transboundary air pollution. Currently, there are no regional ambient SO2 and NOx regulations and control measures of many developing countries including GCC countries. This paper reviewed the experiences of the past acid rain pollution problems in United States, Canada, Europe, Japan and China. In addition, the plausible control measures through application of air pollution abatement technologies, market based regulations were discussed. The study recommended that suitable and locally based measures could be adopted by GCC states to prevent future occurrence of acid rain within the region and beyond.
