Abstract: As a pioneer plant in the gully slopes in the Soft Sandstone Area (SSA) for eco-economical consideration, ten years (1999-2008) planting of seabuckthorn has made 1642.83 km2, or 9.84%, of the total area of SSA change into seabuckthorn coverage. In SSA the landscape has been divided into 9 types, such as seabuckthorn, sand, water, settlement, bush, open vegetation, forest, grassland and unused land. Seabuckthorn type is separated from the bush type for estimating the role of seabuckthron planting. By means of the Markov model, the developing trends of every landscape types can be determined to support the seabuckthorn project which influences the landscape pattern deeply in SSA. The prediction shows that the optimism ratio of seabuckthorn in the future should be 10.21%, the open vegetation 32.25%, and the forest percentage under 10%, which is a very wise tactics to avoid the serious death of various vegetations in SSA to match the local arid eco-environment.

Abstract: Seabuckthorn is regarded as a main eco-economical tree species, and plays an increasing important role in eco-environmental construction in Northwest, Northeast and North China. Our study on artificial seabuckthorn forest in loess hilly region showed that the average rainfall interception rate of 7-10 ages seabuckthorn canopy was 8.5%, and the litter layer of 5-10 ages seabuckthorn forest could intercept 0.89 mm rainfall. Seabuckthorn forest could improve soil infiltration and anti-strike ability through improving soil physical and chemical properties, and the numbers of its hair roots and the depth of its litter layer were the main indices of soil anti-strike ability. The effects of seabuckthorn forest on soil and water conservation increased with its increasing age. In 2-3 ages stage, the effects were weak, and the runoff and sediment were mainly affected by the characters of rainfall. In 4-5 ages stage when the forest became maturing, the annual runoff depth and annual erosion modulus were 1.8-3.2 mm and 24.64 t x km(-2), respectively. In 6-12 ages stage when the forest matured, the runoff and sediment on seabuckthorn woodland changed slowly, the annual runoff depth and annual erosion modulus being 0.3 -3.4 mm and 0-6.75 t x km(-2), respectively, and the characters of rainfall had much less effect on them. In the stage from young (2-5 ages) to mature forest, the sediment charge in runoff changed sharply, ranged from 77. 31 kg x m(-3) to 9.12 kg x m(-3), but in 6-12 ages stage, the sediment content in runoff changed very slowly, and the range was 0-5.09 kg x m(-3).

Abstract: This empirical investigation tries to identify the causes and economic costs of pipeline production losses in the Nigerian oil industry from 1999 to 2008. It brings out the total product and value loss within the selected years. It also shows the frequency of occurrence in pipeline incidences as a result of fire outbreak, vandalization and rupture in various areas in Nigeria. Five null hypotheses were formulated to guide the study and time series data data was collected through archival sources and analysed using descriptive and inferential statistics. Data are presented in tables and graphs. Results show that vandalization has been increasing from 1999 to 2008 with its highest incidences at Port Harcourt pipelines. Production losses due to rupture were less frequent though physical product losses were highest between 1999 to 2006. Fire outbreaks were discovered to unfortunately be a yearly event with its highest evidences at Port Harcourt and Warri pipelines. This led to very high wastages and monetary losses over the years. Some of the recommendations are effective protection guideline policies for oil pipelines to avoid product losses through vandalisation and fire out break regular maintenance of oil pipelines to reduce incidences of rupture and increased participation or partnership with communities where pipelines are located for protection.

Abstract: the main objective of this study was to asses the temporal variation (1999 trough 2008) of air quality in rome, focusing on airborn concentration of selected pollutants (pm10 and pm2.5 mass concentration and particle number concentration, pnc, carbon monoxide, co, nitrogen oxides, no and no2) used for health effects assessment in epidemiological analyses. time series analysis using seasonal kendall test has been applied. a statistically significant decreasing trend was found for primary gaseous pollutants and total particle number concentrations. moreover a decreasing trend was assessed for pm10, pm2.5 and no2 measured at traffic oriented sites even if the estimated reduction was lower compared with no, co and pnc. the urban background pm10 and no2 concentrations seem to be practically unchanged since 1999 as no statistically significant trends were found. all the pollutants show higher slope of the estimated trend line at traffic oriented sites compared with those observed at the urban background. thus a reduction of the intra-city concentration variability throughout the years occurred.

Abstract: Objectives: The aim of the study was to investigate the trends in the incidence of occupational diseases in Lithuania during the period of 1999-2008. The analysis concerned both the individuals with diagnosed disease(s) and the number of diagnosed cases. Material and Methods: Incidence rates were calculated using data from the Republic of Lithuania National Register of Occupational Diseases and data on the employed population provided by the government Department of Statistics. The rates were age-standardized using the direct standardization method. The changes in the incidence rates throughout the study period were analyzed using segmented regression calculated with the JOINPOINT (v. 3.3.1) statistical software. We determined joinpoints in the dynamic lines of the incidence rates and calculated mean annual absolute change and mean annual relative (percentage) change for each period. Results and Conclusions: During the study period, the number of occupational diseases was, on average, 1.5 times as high as the number of individuals diagnosed with such diseases. Joinpoint positions in the dynamic lines of the incidence rates coincided for individuals with occupational diseases and for the cases of occupational diseases. The incidence was found to slightly increase during the period of 1999-2003, then to rise more rapidly during that of 2003-2006, and to decrease from 2006 to 2008.

Plant Pathology Journal , 2007,
Abstract: Seabuckthorn (Hippophae rhamnoides), a multipurpose shrub and native of higher Himalayas is also known as cold desert gold due to its high potential as a bio resource for wetland reclamation, soil erosion, food medicinal and cosmetic industries. Studies conducted on the microbial associates of this plant revealed the presence of 26 fungal species in its rhizosphere. Three fungal entophytes (i.e., Aspergillus niger, Mortierella minutissima and a sterile mycelium) and four species of VAM spores (i.e., Glomus albidum, Glomus fasciculatum, Glomus macrocarpum and Gigaspora margariata) has also been isolated from different plant parts (Root, stem, leaves and bark) and soil samples, respectively.

Abstract: Paediatric admission data on malaria and non-malaria diagnoses were assembled for the period 1999 to 2008 from in-patient registers at 17 district hospitals in Kenya and represented the diverse malaria ecology of the country. These data were then analysed using autoregressive moving average time series models with malaria and all-cause admissions as the main outcomes adjusted for rainfall, changes in service use and populations-at-risk within each hospital's catchment to establish whether there has been a statistically significant decline in paediatric malaria hospitalization during the observation period.Among the 17 hospital sites, adjusted paediatric malaria admissions had significantly declined at 10 hospitals over 10 years since 1999; had significantly increased at four hospitals, and remained unchanged in three hospitals. The overall estimated average reduction in malaria admission rates was 0.0063 cases per 1,000 children aged 0 to 14 years per month representing an average percentage reduction of 49% across the 10 hospitals registering a significant decline by the end of 2008. Paediatric admissions for all-causes had declined significantly with a reduction in admission rates of greater than 0.0050 cases per 1,000 children aged 0 to 14 years per month at 6 of 17 hospitals. Where malaria admissions had increased three of the four sites were located in Western Kenya close to Lake Victoria. Conversely there was an indication that areas with the largest declines in malaria admission rates were areas located along the Kenyan coast and some sites in the highlands of Kenya.A country-wide assessment of trends in malaria hospitalizations indicates that all is not equal, important variations exist in the temporal pattern of malaria admissions between sites and these differences require more detailed investigation to understand what is required to promote a clinical transition across Africa.In recent years several African countries have managed to rapidly scale up the d

Abstract: Ground snow observation data from 1999 to 2008 were used to analyze the temporal and spatial distribution of snow density in China. The monthly maximum density shifted from north to south during the period from October to the following January, and then moved back from south to north during the period from January to April. The maximum snow density occurred at the border between Hunan and Jiangxi provinces in January, where snow cover duration was short and varied remarkably. Snow density in Northeast China and the Xinjiang Uygur Autonomous Region were also high and showed less variation when the snow cover duration was long. Ground observation data from nine weather stations were selected to study changes of snow density in Northeast and Northwest China. A phase of stable snow density occurred from the middle ten days of November to the following February; non-stationary density phases were observed from October to the first ten days of November and from March to April. To further investigate the effects of climatic factors on snow density, correlations between snow density and precipitation, air temperature, snow depth and wind velocity for Northeast and Northwest China were analyzed. Correlation analysis showed that snow depth was the primary influence on snow density.

Abstract: Seabuckthorn is a shrub possible to be entirely capitalized because of the presence of biologically active principles in all plant organs. The seabuckthorn offshoots can be added as supplements in animal feed. For this reason, the study of chemical profile by quantification of total lipids, soluble proteins and assimilatory pigments is important. Our results established that the values of investigated biochemical parameters depend on phenophase when the biological material was harvested and also on analyzed cultivar. The biosyntheses are certainly more intensely in fruit maturation phenophase.
